The reduction unit 1140 reduces the rotational speed generated by the driving motor 1130 and is supported by the reduction unit accommodating unit 1113 and is supported by the reduction gear bracket 1500.

The reduction unit 1140 is coupled to the driving motor 1130 and is coupled to the first reduction member 1143 and the first reduction member 1143 to transmit the rotational force to the motion conversion unit 1150. 1145).

The first deceleration member 1143 may include a first drive gear 1143b driven in engagement with a motor gear (not shown) coupled to the rotation shaft of the drive motor 1130. A first shaft 1143a rotatably supporting the first driving gear 1143b and a first shaft 1143a are coupled to the first reduction gear 1145 while rotating together with the first driving gear 1143b. The physics includes a first driven gear 1145b. Here, the first shaft 1143a is rotatably coupled to the reducer bracket 1500.

The second deceleration member 1145 includes a second drive gear 1145b that rotates in engagement with the first driven gear 1145b, and a second shaft 1145a rotatably supporting the second drive gear 1145b. It is desirable to. It is preferable that the second shaft 1145a is rotatably coupled to the reducer bracket 1500.

The motion converting unit 1150 is coupled to the converting part accommodating part 1114 and converts the rotational motion transmitted from the reduction unit 1140 into a linear motion to enter and exit the main body housing 1110 and combine with the bracket 1500 to open the door ( 10) to move between the open position (see Fig. 10a) and the locking position (see Figs. 5a, 5b, 5c, 10b) in which the door 10 is locked. In this process, the motion conversion unit 1150 also maintains the key position where the main body housing 1110 can be firmly coupled to the bracket 1500, and the door key 1700 described later is provided on the key holder 1300. Movement between a locking position (see FIG. 7B) that is coupled to maintain a supported state without separation and a separation position (see FIG. 7A) where the door key 1700 can be separated from the key rest 1300. Energy may be transmitted to the key post 1300 side.

As shown in FIGS. 3 and 9, the motion conversion unit 1150 linearly moves the rotational force of the conversion bar 1151 and the conversion bar 1151 that are coupled to the same axis as the second axis 1145a and rotate. A conversion guide spring 1153 coupled to the outer circumferential side of the conversion bar 1151 to a fixed pitch and fixedly coupled to the conversion slide 1155 and the conversion guide spring 1153 in the 'X' axis direction. It is preferable to have a conversion slide 1155 which slides between an open position and a locked position along the conversion portion accommodating portion 1114 formed in the longitudinal direction.

The motion conversion unit 1150 further includes a cradle conversion member 1157 which is coupled to one side of the conversion slide 1155 to convert the linear motion of the conversion slide 1155 into a rotational motion.

The conversion bar 1151 has a conversion bar shaft hole 1151a provided in a shape corresponding to an end portion of the second shaft 1145a, which is a fastening means including an interference fit so as to rotate in engagement with the end of the second shaft 1145a; A conversion bar pin 1151b that protrudes on the outer circumference side and rotates along the helical pitch of the conversion guide spring 1153 coupled to the outer circumference side is provided.

With this structure, when the second shaft 1145a rotates, the conversion bar 1151 rotates, and when the conversion bar pin 1151b protruding on the outer circumferential side according to the rotation of the conversion bar 1151 rotates on the second axis 1145a. The conversion bar 1151 which is firmly coupled is only rotated, and the conversion bar 1151 is rotated along the pitch of the conversion guide spring 1153 fixedly coupled to the inside of the conversion slide 1155, and thus the conversion slide 1155 is converted. Sliding guided by the molten part 1114 allows the conversion slide 1155 to linearly move in the 'X' axis direction.

The conversion guide spring 1153 is coupled to the outer circumferential side of the conversion bar 1151 in a state in which the conversion guide spring 1153 is firmly fixed so as not to rotate inside the conversion slide 1155, and is wound in a coil shape having a constant pitch so that the conversion bar pin 1151b is provided between the constant pitches. Can be located.

The conversion slide 1155 includes a structure in which the upper side is opened in an elongated hexahedral shape, for example, moving along the 'X' axis in the conversion part accommodating part 1114. The conversion slide 1155 has a spring-shaped opening / closing which can detect an open position and a lock position at a position corresponding to a hollow main body slide body 1155a and an open / close switch connecting portion 1183 of the main body PCB 1180. Clamp springs formed in the up-and-down direction such that the position springs 1155c, the opening / closing spring holes 1155b to which the opening / closing position springs 1155c are coupled, and the clamp spring fixing member 1178a, which is a plate shape of the clamp return springs 1178, are coupled to each other. It is preferable to include a coupling slot 1155f and a slide rack 1155e provided in a rack shape on the side surface and engaged with the cradle conversion pinion 1157b of the cradle conversion member 1157.

The cradle conversion member 1157 is rotatably coupled with the slide rack 1155e protruding from the cradle conversion shaft 1157c coupled to the main body housing 1110 and the outer circumferential side extending from the cradle conversion shaft 1157c. (1155e) a cradle conversion pinion (1157b) that can convert the linear motion to a rotational movement, and a cradle cam leg hole provided in a polygonal shape on the same 'Z' direction axis of rotation (1157c) on the upper side ( 1157a) is preferred.

By the structure of the motion conversion unit 1150 as shown in FIG. 9 to be described later, one operation and the door key 1700 is locked and opened in the storage box 20 by one drive motor 1130. Has the advantage of simultaneously performing two operations, one operation that can be separated and seized on the key holder 1300.

That is, the first movement to the first operation of the opening and locking of the door 10 and the door key 1700 are separated and caught on the key holder 1300 at one power generated and transmitted from the driving motor 1130. Two movements to the second operation can be made at the same time. Therefore, in the prior art, a power source including a total of two motors, one for each of the first motion and the second motion, is required, which consumes a lot of power, is complicated in structure, complicated by electrical circuits, and has a large number of parts. In the present invention, problems and disadvantages, such as manufacturing and the like, are not easy and there is a high possibility of failure.

Here, the process of transmitting power from the driving motor 1130 to the conversion slide 1155 according to an embodiment of the present invention is as follows.

First, when power is applied from the main body PCB 1180 to the motor power supply spring 1133 of the drive motor 1130, and the drive motor 1130 is rotated, the rotational force of the drive motor 1130 is not shown. The rotational force is transmitted to the conversion bar 1151 through the gear 1143b-the first driven gear 1145b-the second driving gear 1145b-the second shaft 1145a. When the conversion bar 1151 rotates, the conversion bar pin 1151b rotates, and the conversion bar pin 1151b pushes the conversion guide spring 1153 fixedly coupled to the conversion slide 1155 at a constant pitch. The conversion slide 1155 accommodated in the conversion part accommodating part 1144 of the main body housing 1110 by the force pushing the conversion guide spring 1153 is slid along the 'X' axis direction to slide the main body housing 1110. It moves between the open position and the lock position while entering and exiting the through hole 1116. The detection information indicating that the opening position and the locking position has been reached is coupled to the opening / closing spring hole 1155b of the conversion slide 1155 to protrude into the main body PCB 1180 to be in contact with the opening / closing switch connecting portion 1183 to open and close the spring. By 1155c.

The opening / closing position spring 1155c has an elastic force and an electrically good conductivity. A diameter (see 'd spring-upper' of FIG. 12 (c)) of the opening / closing position spring 1155c, which is a part in contact with the opening / closing switch connecting portion 1183 of the opening / closing position spring 1155c, is illustrated in FIG. 12 (c). As described above, the width of the PCB slot 1186b of the opening / closing switch connecting portion 1183 is smaller than the width of the slot 186b of FIG. 12C. However, the width (see 'Wcontack' in Fig. 12 (c)) of the portion of the PCB slot neck 1186b of the opening / closing switch connecting portion 1183 to reach the opening position and the locking position is the opening / closing position spring 1155c. 1155c) (see 'd spring-upper' in Fig. 12 (c)).

On the other hand, in the main body PCB 1180, four plating regions including gold plating are formed at four edges of the open / close switch connecting portion 1183 contacting the open / close position spring 1155c (Fig. 12 (c)). See 'coat1-1' 'coat1-2' 'coat2-1' and 'coat2-2').

That is, even if the conversion slide 1155 is slightly shaken while the opening / closing position spring 1155c moves along the opening / closing switch connecting portion 1183 formed long in the 'X' axis direction, the width of the opening / closing switch connecting portion 1183 is opened and closed. Since the diameter of the spring 1155c is greater than that of the body PCB 1180, the signal cannot be transmitted.

However, in the open position, even though the conversion slide 1155 is slightly shaken, two electrically connected plating regions of the two open / close switch connecting portions 1183 in the open position due to the deformation of the open / close position spring 1155c having elastic force. (See 'coat2-1' and 'coat2-2' in FIG. 12 (c)) can be contacted to signal that the conversion slide 1155 has reached the open position to the main body PCB 1180. In response to the signal, the main body PCB 1180 may stop the operation of the driving motor 1130 and control the display unit 1383 of the cradle PCB 1380 to display the OPEN.

On the other hand, two plating regions (see 'coat1-1' and 'coat1-2' in Fig. 12 (c)) which are the same in the locked position and are not electrically connected at this time can be contacted by the opening / closing position spring 1155c. It is possible to signal to the main body PCB 1180 that the conversion slide 1155 has reached the locked position. In response to the signal, the main body PCB 1180 may stop the operation of the driving motor 1130 and control the display to display “CLOSE” on the display unit 1383 of the cradle PCB 1380.

That is, the pair of plating regions (for example, 'coat1-1 and coat1-2' pair or 'coat2-1 and coat2-2' pair) positioned on the left and right sides of the opening / closing position spring 1155c must be in contact with each other to open the position. And the locking position may be detected by the opening and closing position spring 1155c.

In addition, the opening / closing position spring 1155c has a structure in which the outer diameter becomes larger and larger toward the upper side (see the enlarged view of FIG. 12 and section d-d). That is, the outer diameter of the upper side is 'd spring-upper', and the portion that is coupled to the conversion slide 1155 and the lower outer diameter of the center portion to approximately the center portion is 'd spring-lower', and gradually goes from the lower outer diameter to the upper outer diameter. The spring coil outer diameter becomes larger.

This structure is deformed to be slightly inclined by the force in the direction in which the opening and closing position spring 1155c is located in the PCB slot neck (1186b) moving the conversion slide 1155 as shown in section dd ('section d-d of FIG. 12) The area of the contact coil of the wound coil of the open / closed position spring (1155c) is coated ('coat1-) when the angle' k 'between the vertical axis' k1' and 'k0' is tilted about 'k2'. 1 'and' coat1-2 'can be effectively contacted at the locked position and' coat2-1 'and' coat2-2 'are simultaneously contacted at the open position), so that the electrical connection can be made easier. Can be.

Due to this structure, even if the movement of the conversion slide 1155 and the like is slightly vibrated and shakes while the conversion slide 1155 moves the locking position and the open position, the conversion slide 1155 is stably connected to the main body PCB 1180. Operational status can be detected, allowing the detected information to be delivered reliably and effectively.

The bracket detecting unit 1160 detects whether the door 10 is located at the locked position. The bracket detecting unit 1160 protrudes from the lock body 1100 to determine whether it is in contact with the sensing arm catching jaw 1541 of the sensing arm receiving unit 1540 formed in the bracket 1500 and serves as a reference for the rotational movement. A sensing arm 1163 including an arm hinge 1163a, a sensing support member 1161 supported by the bracket sensing unit 1115 of the lock body 1100, and one side of the sensing spring of the sensing support member 1161. A sensing spring 1165 is elastically accommodated in the receiving groove 1161a to elastically pressurize the sensing arm 1163.

The sensing spring 1165 has a conductivity and is wound in a coil shape and is extended from one side of the sensing spring body 1165a accommodated in the sensing spring receiving groove 1161a and the sensing spring body 1165a to the sensing arm 1163. When coupled to provide the elastic force of the sensing spring body 1165a while on the other hand is in contact with the contact member receiving portion 1184a of the body PCB (1180) and in contact with the body PCB (1180) (in this case of the sensing spring 1165) The elastic force presses the sensing arm 1163, see FIG. 11B. The sensing arm 1163 is not in contact with the bracket 1500 (in this case, the elastic force of the sensing spring 1165 causes the sensing arm 1163 to bracket. It is in a state in which it is in a state in which it is unable to overcome the pressing force by contacting the 1500. Refer to Fig. 11A) When it is determined that the locking position of the door 10 has not been reached, the sensing arm 1163 is moved to the bracket ( In contact with 1500 to lock the door 10. Sensing spring on-off contact member 1165b capable of providing information that has been reached, and sensing conductive member receiving portion 1184b of main body PCB 1180 having a bent shape extending from the other side of sensing spring body 1165a. It is preferable to have a sensing spring conduction member 1165c which is excellent in electrical connection and is firmly supported with elastic force.

The structure in which the sensing spring conduction member 1165c is coupled to the sensing conduction member accommodating part 1184b of the main body PCB 1180 is the same as the structure in which the above-described motor spring conduction member 1133b is coupled to the driving motor connection 1118. Therefore, detailed description is omitted.

The operation of the bracket detecting unit 1160 having such a configuration will be described in detail with reference to FIGS. 11A and 11B.

First, FIG. 11B illustrates a state in which the sensing spring 1165 is elastically pressurized to the sensing arm 1163 while the door 10 is open, and rotation is made around the sensing arm hinge 1163a according to the elastic pressing force. In this case, the sensing spring on-off contact member 1165b of the sensing spring 1165 contacts the plating area of the contact member accommodating portion 1184a so that the sensing arm 1163 is attached to the main body PCB 1180 by the bracket 1500. ), The main body PCB 1180 may determine that the door 10 is not in the locked position.

Next, when the user closes the door 10, the sensing arm 1163 is accommodated in the sensing arm accommodating part 1540 of the bracket 1500 such that a contact force, which is a force that contacts the sensing arm catching jaw 1541, is detected by the sensing spring 1165. ) Overcomes the elastic force that elastically presses the sensing arm 1163 and rotates the sensing arm 1163 about the sensing arm hinge 1163a. Accordingly, the sensing spring on-off contact member 1165b of the sensing spring 1165 does not come into contact with the plating area of the contact member accommodating portion 1184a as the sensing arm 1163 rotates, thereby detecting the sensing spring 1165b on the main body PCB 1180. The main body PCB 1180 may determine that the arm 1163 is located in the bracket 1500 so that the door 10 is in the locked position.

By the structure of the bracket detecting unit 1160, it is possible to check, determine, and control whether the door 10 is in the locked position.

As shown in FIGS. 3, 5C, 10A, and 10B, the door clamp 1170 is bent upward at one end of the clamp body 1171 and the clamp body 1171 of the rectangular plate shape, and the bracket ( The clamp catching portion 1171 caught by the clamp catching member 1520 of the 1500 and the other end of the clamp main body 1171 are bent upward, and are caught by the clamp catching jaw 1120a of the main body cover 1120 and clamp return spring ( The clamp skirt 1177 in contact with the clamp spring elastic member 1178b to which the elastic pressing force of 1178 is provided, and the clamp catch portion 1173 and the clamp skirt 1177 of the clamp body 1171 are not other than the bent region. A clamp hinge 1175 is formed in the middle region of the side and protrudes to the outer circumferential side and rotatably supported by the hinge accommodation portion 1155d of the conversion slide 1155.

The clamp return spring 1178 is coupled to the clamp spring coupling slot 1155f of the conversion slide 1155 so that the clamp catch portion 1173 does not catch the clamp catch portion 1173 of the bracket 1500. It is possible to provide an elastic force to the clamp skirt (1177) of the conversion bar 1151 in the center to stably receive and support.

The clamp return spring 1178 is formed in a rectangular plate shape and penetrates through the center of the clamp spring fixing member 1178a and the clamp spring fixing member 1178a, both ends of which are coupled to the clamp spring coupling slot 1155f. Clamp spring through hole (1178c) that can be supported, and is bent extending from the clamp spring fixing member (1178a) to press the clamp skirt (1177) to clamp the clamp skirt (1177) clamping member (1520) of the bracket (1500) It is preferable to have a clamping spring elastic member 1178b elastically pressurized to an unclamped position not to be caught).

On the other hand, the force applied to the clamp return spring (1178) and the clamp engaging portion (1173) is arranged in the left and right direction, not the 'X' axis direction of the vertical direction in the gravity direction, so that the gravity of the clamp engaging portion (1173) itself, etc. Since there is no need to consider, it is possible to maintain the key position (see 'CLAMPING' in Fig. 10b) with very little force.

10A and 10B, a position where the conversion slide 1155 is difficult to be separated from the bracket 1500 and a release position where the conversion slide 1155 is easily separated from the bracket 1500 are described with reference to FIGS. 10A and 10B. The process of working between 'UNCLAMPING') is as follows.

That is, the above-described locking position and the open position mean a position in which the door is opened and closed with respect to the storage box, and the lock position corresponds to whether the door is separated in the plate direction in relation to the storage box in the closed position of the door. That is, the key position is to have the effect of preventing the separation or breakage of the door from the storage box by inserting the tool in the gap between the bracket and the lock body. Further, in this position, the plate surface of the clamp body 1171 and the clamping member 1520 and the jaw slide through hole 1116 come into contact with each other to grasp the cover 1300 and apply an external force to open the door 10. The plates are in contact with each other to maintain the lock position without moving outward.

First, the state of FIG. 10A shows a state in which the door 10 is opened because the conversion slide 1155 does not approach the bracket 1500. In this case, the elastic pressing force of the clamp return spring (1178) acts on the rear side of the clamp catching portion (1173) of the door clamp (1170) to act as the clamp catching portion (1173) toward the center of the clamp hinge (1175). The clamp skirt 1177 on the opposite side of the clamp catching part 1171 and the clamp hinge 1175 is lowered like a seesaw, and the clamp skirt 1177 when the slide receiving part 1530 of the bracket 1500 is moved in and out. ) Is not caught by the clamping member 1520.

Then, when the conversion slide 1155 moves forward and comes to the locked position as shown in FIG. 10B, the clamp catching portion 1173 contacts the clamp catching jaw 1120a of the main body cover 1120 and the force applied to the positive slide is positive. When acting in the 'X' axis direction, the contact force of the clamp catching jaw 1120a overcomes the elastic pressing force of the clamp return spring 1178 acting on the clamp engaging part 1173 in the negative 'X' axis direction. The clamp catching part 1171 is rotated clockwise about the hinge 1175. By the seesaw action according to the clockwise rotation, the clamp skirt 1177 located on the left side of the clamp hinge 1175 is raised clockwise. By this action, even if an inappropriate external force (force force acting between the bracket 1500 and the lock body 1100) acts in the 'X' axial direction, the door clamp 1170 attached to the main body of the door 10 is applied. Improper opening / closing of the door 10 because the clamp skirt 1177 is caught by the clamping jaw 1120a of the bracket 1500 (for example, the door 10 is forcibly locked). ) To secure the locked state of the door 10 from the act of cutting the contents of the inside of the storage box 20), thereby improving the safety of opening and closing the door 10.

Then, when the conversion slide 1155 moves from the locked position to the open position, the pressing force generated by the clamp skirt 1177 in contact with the clamp catching jaw 1120a becomes less and less, and the elastic force of the clamp return spring 1178 is clamped. The clamp catching portion 1173 does not catch the clamp catching jaw 1120a without shifting the slide while the clamp catching portion 1173 is moved downward to move to the open position by acting on the upper side by acting on the act 1177. Move with 1155.

Another embodiment of the process of moving between this lock position and the unlock position is shown in FIGS. 13A and 13B. The other part is almost the same as the above-described example, except that the clamp return magnet 2178 and the clamping position elastic member 2179 are provided instead of the clamp return spring.

With this structure, as shown in FIG. 13A, the clamp returning magnet 2178 is pulling the clamp main body 1171 downward when the clamp main body 1171 of the door clamp 1170 is in the unlocking position. On the other hand, the clamping position elastic member (2179) is not in contact with the clamp skirt (1177) is opened without being elastically deformed (the open length at this time see 'L1' in Fig. 13A).

When the next conversion slide 2155 is moved, the clamp skirt 1177 is pressed against the clamping position elastic member 2179 to pressurize the clamping position elastic member 2179 to elastic deformation (see 'L2' in FIG. 13B), and such elastic deformation force. As a result, the door clamp 1170 moves the clamping portion 1173 in the negative Z-axis direction as in the seesaw action with respect to the clamp hinge 1175. Then, the clamp catching part (1173) is caught by the clamp catching member (1520) can maintain the locked state even if an external force is applied.

In this case, the magnetic material of the door clamp 1170 or the clamp body 1171 may include a steel plate on which magnetic force may be generated by a magnet. In addition, the clamp return magnet 1178 may be, for example, one or two magnets having a diameter of 3 mm and a length of 3 mm. By such a structure, it is possible to operate more efficiently and stably between the lock position and the lock release position due to the weight of the door clamp 1170 in the upside down or lying down state.

On the other hand, as mentioned in FIG. 12 and in the middle, the means electrically connected to the main body PCB 1180 to receive power or transmit a signal from the main body PCB 1180 is excellent in conductivity, elastic and deformed state Motor power supply spring 1133, drive motor connecting portion 1182, sensing spring 1165 and contact member accommodating portion 1184a and sensing energizing member accommodating portion 1184b made of a material that can be stably maintained, opening / closing position spring ( 1155c and the on / off switch connection unit 1183 may be more stably and effectively connected. A plating area (coat, coat1-1, etc.) may be appropriately provided around the accommodating or connecting

parts

1181, 1182, 1183, 1184, and 1185, which may be formed through the main body PCB 1180 and electrically connected thereto. Increased wear resistance against wear due to electrical connection and contact with the springs. Here, reference numeral '1181' is an area in which the power source of the battery accommodated in the battery accommodating part 1111 and the main body PCB 1180 can be electrically connected.

In other words, according to the present invention, the electrical wire and / or the sensor and / or the printed circuit board (PCB) are connected to each other by means of a connector and / or a soldering device. Like this connector and / or soldering structure, power and / or signal can be transmitted / received by using coil or spring-shaped material which has excellent conductivity and elasticity, thus preventing work environment degradation and contamination due to soldering, etc. Problems such as a complicated circuit structure due to the like can be solved.

The key holder 1300 may be coupled through the lock body 1100 and the door 10 coupled to the inside of the door 10 to mount the door key 1700. In addition, the key holder 1300 determines whether the door key 1700 is mounted to the door key arm 1311 and determines whether the ID of the door key 1700 matches the ID of the door 10. Information and move the door key 1700 between a locking position (see FIG. 7B) that is not detachable from the door key arm 1311 and a removable position (see FIG. 7A). As described above, the operation of the separation position and the locking position proceeds simultaneously with the operation of the lock position and the open position by the operation of the driving motor 1130, which is the one rotational force described above.

The key holder 1300 is coupled to the lock body 1100, penetrates the door 10, protrudes from a through-hole (not shown) of the door 10, and is bent to extend between the plate keys of the door 10. 1700 is provided with a door key arm 1311 to form a space for mounting, the mounting body 1310 open to the outside in the 'Z' axis direction to support the accommodated components, and the open mounting body It includes a cradle cover 1320 for opening and closing the 1310.

The key holder 1300 is a door key locking unit 1330, a holder cam 1340, a door key ground spring 1350, a connector pin 1360, an inner fixing part 1370, a holder PCB 1380, It is preferable to have a cradle fixing member 1390.

The material of the parts constituting the key holder 1300 is except for parts requiring electrical connection (door key ground spring, connector pins, holder PCB, etc.) and parts requiring rigid coupling (steel holder fixing members, etc.). It is preferable that it consists of synthetic resin.

As shown in FIG. 6A, fastening means (not shown) such as ribs and bolts protruding from the cradle cover 1320 are supported or penetrated to the cradle main body 1310 so as to couple and fix the cradle cover 1320. The holder cover fastening hole 1310a which may be, the door key locking hinge hinge 1312 which protrudes from the surroundings so as to be a support point of operation during the seesaw operation of the door key locking portion 1330 which will be described later, and the main body PCB 1180. And / or a plurality of connector pin holes 1313 formed therethrough so that the connector pins 1360, which may be electrically connected to the door key 1700, are coupled to each other, and the locking means including bolts and the lock body 1100 and the key holder. The fastening member hole 1314 to which the holder fixing member 1390 to which the 1300 can be coupled is coupled, and the ground spring protrusion 1352, which is a protruding portion of the door key ground spring 1350, may protrude outward. Ground spring hole 131 formed through the door key arm 1311 side 5) and the door key catching hole 1316 formed through the door key arm arm 1311 side to allow the hook hook 1332 to enter and exit the door key 1700, and the holder cam 1340 are coupled to each other. It is preferable that the holder cam hole 1317 that can rotate.

The cradle cover 1320 opens and closes the open area of the cradle main body 1310 and is exposed to the outermost side in the 'Z' axis direction to form a part of the exterior together with the cradle main body 1310.

A cap hole 1321 is formed in the cradle cover 1320 on the same axis as the cradle cam 1340, and a cap 1323 is detachably coupled to the cap hole 1321.

Cap 1323 is provided with a plurality of leg-shaped cap hook portion 1325 that is detachably fixed to the cap hole 1321, the cap 1323 is provided with a transparent material is a cradle PCB (through the cap 1323) The display 1383 of 1380 can be seen. Since the cap 1323 is coupled to the cap hole 1321 on the same axis as the cradle cam 1340, when the cap 1323 is removed, the cap 1323 may be manually operated to lock or open the door 10.

For example, assume that the door 10 is not opened because the driving motor 1130 does not operate even when the door key 1700 is mounted on the door key arm 1311 while the door 10 is locked. In this case, according to the present invention, the user removes the cap 1323 from the cap hole 1321 and then shows a jig (see 'JIG' in FIG. 7C) including a screwdriver, a hexagon wrench, and the like shown in FIG. 7C. As shown in FIG. 7C, the cap hole 1321 and the cradle inner fixing part 1370 penetrate through the cam manual operation hole 1344 of the cradle cam 1340 on the same axis (see 'Z1' in FIG. 7C). ), Through the cradle PCB 1380, the door key locking portion 1330 in order to be coupled to the cam manual operation hole 1344. When the jig is rotated, the rotational force is transmitted to the cradle cam 1340-door key catching part 1330 upward (negative 'Z' axis direction), and the door key catching part 1330 is caught at the separated position. Moving to the lower side (positive 'Z' axis direction) of the cradle cam 1340-the cradle conversion member 1157-the conversion slide 1155, the rotational force is transmitted to the conversion slide 1155 in the locked position The door clamp 1170 is also moved to the unlocked position at the same time as the door 10 is moved to the open position so that the door 10 can be opened.

If there is no manual operation as in the present invention, it can be seen that it is very inconvenient because the door 10 may be damaged or the configuration of the door lock device 100 may be forcibly broken or damaged.

Of course, during such manual operation, the display unit 1383 may be controlled by the main body PCB 1180 such that an alarm sounds unconditionally and at the same time a warning light blinks.

The door key catching portion 1330 may be provided in one side of the main body (not shown) having a somewhat bent shape, and protrude outward to protrude outward to allow the door key catching hole 1316 to enter and exit the door key 1700. The hook hook 1332 is engaged with the hook hook groove 1790 and the engagement is released, and the upper cam member 1343 is provided on the other side of the main body and the height ('Z' axis direction) is changed while the holder cam 1340 is rotated. And a hook contact 1331 provided so that the hook hook 1332 can enter and exit the door key catching hole 1316, and the hook hook 1332 has a height change according to the rotation of the cradle cam 1340. It is preferable to include a locking hinge 1333 coupled to the door key locking hinge shaft 1312 to be a support point of the seesaw movement in the course of the seesaw movement to enter and exit 1316.

In addition, the door key catching portion 1330 has a latching hinge 1333 and a cam contacting portion 1331 facing the locking hook 1332, the latching hinge 1333, and the cam contacting portion 1331 in the 'Z' axis direction. Door key locking part 1330 is coupled to the main body between the door key locking part 1330 so that the locking hook 1332 of the door key locking part 1330 does not protrude from the plate surface of the door key clutch arm 1311. It is preferable to further include a locking return spring (1334) for elastically pressing the 1330.

Referring to FIGS. 7A and 9, the force and distance acting to lock and separate the door key 1700 by the key holder 1300 by the configuration of the door key locking unit 1330 will be described below.

First, the cam contact portion 1331 lifts the cam contact portion 1331 in the negative 'Z' axis direction, which is contacted with the cam contact portion 1331 of the door key locking portion 1330 and acts as the height of the mount cam 1340 increases. (See 'Fcam' in Fig. 9) is the force pressing in the positive 'Z' axis direction from the locking hook 1332 to the right around the locking hinge axis 1333, which is the support point of the seesaw motion (Fig. 9 Act as a 'Fhook' to keep the door key 1700 in the locked position.

The action of this lifting force 'Fcam' and the pressing force 'Fhook' is the central axis of the force acting from the center axis of the hinge axis 1333 (see 'Z0' in FIG. 7A). Z1 ',' Z2 ', and' Z3 '), and distance (see' L1 ',' L2 ',' L3 'in FIG. 7A). In other words, it is advantageous to make 'L3' shorter than the distance 'L2', so that 'L3' is shorter than 'L2' if possible in the range where deformation can be made.

In this process, the force of the catching return spring 1334, which is a force opposite to the force for lifting the cam contact portion 1331 in the negative 'Z' axis direction (see 'Fcam' in FIG. 9) ('Fspring in FIG. 9). ') Acts on the door key locking portion 1330 to offset the lifting force (Fcam).

Thus, in order to offset the lifting force 'Fcam' as described above while maintaining the return elastic force of the catching return spring 1334 in the present invention, the catch return spring 1334 is separated from the center axis of the catching shaft 1333. By minimizing the distance (refer to 'L1' in FIG. 7A), the door key 1700 can be stably held at the locked position while using less force.

That is, by such a structure, the locking position and the separation position of the door key locking portion 1330 can be operated with very little force, thereby making the structure simple and convenient to use.

The cradle cam 1340 is coupled to the cradle cam hole 1317 of the key holder 1300 in the 'Z' axis direction and is coupled to the cradle converting member 1157 to the lower side (positive 'Z' axis direction) to rotate the upper side. (The negative 'Z' axis direction) is engaged with the door key locking portion 1330 to rotate.

The cradle cam 1340 is a rod-shaped cam main body 1321 having a 'Z' axis direction in a longitudinal direction, and a cradle cam leg hole 1157a of the cradle converting member 1157 is engaged with the cradle to rotate and engage. An upper cam member 1343 having a cam leg 1342 having a shape corresponding to the shape of the cam leg hole 1157 a and a contact surface inclined with respect to the Z 'axis direction so that the height of the engaged portion changes as it rotates upward. And, a cam catching jaw 1345 rotatably supported by the cradle cam hole 1317 of the cradle main body 1310 and a jig including a driver capable of manual operation to rotate. It is preferable to have a cam manual operation hole 1344 penetrated by a predetermined depth along the center axis (see 'Z7' in FIGS. 7A and 7B), for example, in a hexagonal cross section or the like.

The operation of the door key catching unit 1330 and the cradle cam 1340 will be described in detail with reference to FIGS. 7A and 7B.

First, FIG. 7A illustrates a state where the door 10 is closed because the conversion slide 1155 is in a locked position, and the height at which the holder cam 1340 and the door key catching portion 1330 are engaged is as shown in FIG. 7A. It is marked with 'H1'. In this case, the door key 1700 can be detached without the door key catching portion 1330 protruding from the plate surface of the door key arm 1311 by the force of the catching return spring 1334. In the closed state, the user may detach and hold the door key 1700 and store it in a wrist or cuff.

Next, when the user mounts the door key 1700 on the door key arm 1311 and detects it, the driving motor 1130 rotates and the cradle cam 1340 rotates so that the upper cam member 1343 inclined surface and the door of the upper side. The cam contact portion 1331 of the key catching portion 1330, in which the cam contact portion also meshes with the inclined surface of the upper cam member, changes the height difference according to the rotation of the upper cam member (difference between 'H1' and 'H2' in FIG. 7A). It is preferable to have an inclined shape in order to increase the meshing height) to 'H2' which is raised in the negative 'Z' axis direction as shown in FIG. 7B. Due to the height difference (H2-H1, the rise of the height) by the seesaw operation of the door key locking portion 1330 made around the locking axis (1333) is a locking hook 1332 is a locking hook of the door key 1700 Protruding from the plate surface of the door key arm 1311 so as to descend to the receiving groove 1790 side can be engaged to hold the door key 1700 in the locking position. In such a state that the door key 1700 is caught and the user cannot remove the door key 1700, the user can open the door 10 to take out clothes or put clothes inside the storage box 20. .

That is, this operation process can be seen that the drive motor 1130 is a driving force as shown in Figure 9 as described above.

Thus, in the prior art, two kinds of first power source including a motor for moving the open position and the locking position of the door 10 and a second power source including a motor for moving the locking position and the separation position of the door key 1700. A power source was needed.

On the other hand, according to the present invention, it can be seen that the opening position and the locking position movement of the door 10 and the locking position and the separation position movement of the door 10 are made by one power source as described above.

Therefore, according to the present invention, the power source including the driving motor 1130 is one, and the power consumption is reduced, and due to the reduction of related components, circuit configuration, sensor sensing structure, etc. , Efficiency, safety, etc. can be improved.

And a sensing arm receiving portion 1540 having a sensing arm catching jaw 1541 in contact with each other.

The door key 1700 is a means that a user can carry and open and close the door 10. The door key 1700 is coupled to a key body 1710 and one side of the key body 1710 to store an object including clothes. The key ID member 1770 having ID information for the storage box 20 to the door 10 is coupled to the other side of the key body 1710 to mount the door key 1700 on the door key support arm 1311. In this case, the door key grounding spring 1350 and the ground member 1750 which can be grounded, and a key having a hook hook groove 1790 which is engaged with the key body 1710 to form an appearance and the hook hook 1332 is engaged. It is preferable to have a cover 1730.

In this structure, when the user mounts the door key 1700 on the key holder 1300, it is determined whether the door key 1700 matches the ID of the door 10 through the door key ground spring 1350. ) Can be understood from the door key ground spring 1350 that is electrically connected to the door. Similarly, information about whether the door key 1700 is mounted on the key holder 1300 may be grasped from the door key ground spring 1350 electrically connected to the ground member 1750.

Here, reference numeral 1184, which has not been described, includes a contact portion connecting portion 1184a and a sensing conductive member connecting portion 1184b as the bracket detecting portion connecting portion.

Looking at the operation of the door lock device 100 according to the present invention having such a configuration in detail as follows.

First, when power is supplied from the outside or the power is supplied from the built-in battery, the main body PCB 1180 and the cradle PCB 1380 prepare for operation.

When a user enters a bath using a multi-use facility, the user receives the door key 1700 from the administrator and mounts the door key 1700 on the corresponding key holder 1300.

In this case, the door 10 may be in the open position, and the door 10 may be in the locked position.

In the open position, since the bracket detecting unit 1160 is in the open position, the user does not separately open the door 10 in the main body PCB 1180, and the user opens the door 10 to open an object including clothes. In the storage box 20, the door 10 is closed, and the bracket detecting unit 1160 waits for information indicating that the door 10 is located in the locked position. In this case, the user may mount the door key 1700 on the key holder 1300 to check whether the ID information of the door 10 matches with the main body PCB 1180.

However, when the user first uses the door 10 in the locked position, the conversion slide 1155 is in the locked position, the opening / closing position spring 1155c is also in the locked position, and the clamp locking portion 1173 is In the clamped position, the door key catching portion 1330 is in a detached position, and the bracket sensing portion 1160 is also located in the locked position, or preferably in a state of sensing such a position.

When the user first mounts the door key 1700 on the key holder 1300, the main body PCB 1180 detects this and determines that the user wants to open the door 10. FIG.

Accordingly, the information communicated by communicating the information of the mounted door key 1700 through the door key ground spring 1350 electrically connected to the key ID member 1770 and the ground member 1750 of the door key 1700. Is transmitted to the cradle PCB 1380 and / or the main body PCB 1180. The main body PCB 1180 determines whether the door key 1700 matches the door lock device 100 based on the transmitted information.

If the result of the determination is inconsistent, a blinking or alarm sound is issued or the display or information indicating that the display unit 1383 does not match is provided to the user.

As a result of the determination, when the information of the door key 1700 and the door lock device 100 match, the main body PCB 1180 supplies power to the driving motor 1130 to control the driving motor 1130 to rotate.

After the rotational force is transmitted to the first reduction member 1143-the second reduction member 1145-the conversion bar 1151 by the rotation of the driving motor 1130, the rotational movement is converted into the linear movement with the conversion guide spring 1153. The conversion slide 1155 is moved by the bar pin 1151b and moves toward the slide through hole 1116 through the slide receiving portion 1530 in the positive 'X' axis direction.

At the time when the movement is completed, the opening / closing position spring 1155c is in contact with both plating regions (see 'coat2-1' and 'coat2-2' in Fig. 12 (c)) in the open position of the PCB slot neck 1186b. Notify that you have reached. The main body PCB 1180 that recognizes that the opening / closing position spring 1155c reaches the open position controls to stop the operation of the driving motor 1130.

In this movement process, if a little moving from the locked position to the open position, the clamp catching portion (1173) is separated from the clamp catching member (1520) and the elastic force of the clamp return spring (1178) acts so that the clamp skirt (1177) conversion slide (1155) In the process of descending and moving to the center side of the) is not caught by the clamping member 1520.

On the other hand, as shown in Figure 9 at the same time by the linear movement of the slide slide 1155, the holder conversion member 1157 is rotated by the operation of the holder conversion pinion (1157b) engaged with the slide rack (1155e). . According to the rotational movement of the cradle conversion member 1157, the cradle cam 1340 engaged with the cradle conversion member 1157 is rotated, and the cam cam 1313 having a cam shape inclined to the cradle cam 1340 is also rotated, and the top cam is rotated. A height difference (see 'H1' and 'H2' in FIG. 7B) occurs due to the characteristics of the inclined cam member as the member 1343 rotates, and the cam contact portion 1331 of the door key catching portion 1330 engaged with the member 1343 is engaged. Will rise.

As the cam contact portion 1331 of the door key catching portion 1330 rises, the engaging hook 1332 on the opposite side, which performs the seesaw movement with respect to the latching shaft 1333, is lowered. Due to this lowering, the locking hook 1332 protrudes from the plate surface of the door key arm 1311, and the door key 1700 held between the plate surface of the door key arm 1311 and the plate surface of the door 10 is locked. Engaged in the hook receiving groove 1790, the door key 1700 may maintain a locking position that is not separated from the key holder 1300.

Thus, the user can open the door 10 to put the article containing the clothes inside the storage box 20 and the door key 1700 can be separated from the key holder 1300 to the key holder 1300 without having to carry it separately. It can be mounted in a locked position that can not be.

Accordingly, when the user opens the door 10, the sensing spring 1165 of the bracket detecting unit 1160 is separated from the braking detecting arm catching jaw 1541 and contacts the contact member accommodating portion 1184a, thereby contacting the main body PCB 1180. The door 10 may provide open information.

When the door 10 is opened, the user can store the water in the storage box 20 and when the door 10 is closed after all the items are put in, the sensing arm 1163 of the bracket detecting unit 1160 detects the bracket 1500. The sensing spring on-off contact member 1165b coupled to the sensing arm 1163 is received by the arm receiving unit 1540 and is in contact with the sensing arm locking jaw 1541 to the contact member receiving unit 1184a. The door 10 is in a locked position, thereby transmitting to the main body PCB 1180.

When these two pieces of information (in this case, the sensing arm 1163 is in the locked position and the door key 1700 is in the locked position) are input and the main body PCB 1180 grasps, the main body PCB 1180 is in the opposite direction as described above. Rotating the drive motor 1130 to move the conversion slide 1155 from the open position to the locked position to move the door key locking portion 1330 from the locked position to the separated position. As a result of the movement, when the opening / closing position spring 1155c reaches the locking position of the main body PCB 1180, the rotation of the driving motor 1130 is stopped and the display unit 1383 displays the locking state. Can be controlled from Thus, the user may move the door key 1700 in combination with the wrist, ankle, etc. by separating the door key 1700 at the separation position from the key holder 1300.

Of course, in this process, the display unit 1383 may control the main body PCB 1180 to display a state in which each operation process or operation is completed so that the user may know through the transparent cap 1323 to the outside.

And, if necessary, for example, when the user's door key 1700 is different from the information of the door 10 to the information of the door lock device 100, when manually operating the cradle cam 1340, the lock When the detection arm 1163 is in the open position without the door key 1700 in the key holder 1300 at the position, when the remaining battery capacity is 10% or less, the display unit of the holder PCB 1380 in the main body PCB 1180 ( 1383) can sound alarms and alarms at the same time.

On the other hand, the present invention has been described a case in which the door key 1700 is in the form of a band to hang or carry the user's wrist or ankle. However, if necessary, the door lock device 100 according to the present invention may be replaced with a key holder 1300 without an input such as a number key attached to a general home door without the door key 1700.

In addition, there may be a case in which a door key (not shown) having a shape of being inserted and rotated is used.

In this case, unlike the embodiment described above, the cap 1323 may be manually operated without a portion for mounting the door key 1700, and the electrical connection may be processed in the same manner as the above-described embodiment.

Accordingly, according to the present invention, while the door is locked and opened using one drive motor, a door key including a band-shaped key can also be locked and released to the door lock device, thereby using two drive motors. It is possible to provide a door lock device capable of simultaneously operating.

In addition, it is possible to provide a door lock device that can effectively maintain the locking position or the lock position using a small force.

While various embodiments of the present invention have been illustrated and described herein, it will be apparent to those skilled in the art that the present invention may be modified without departing from the spirit or spirit of the invention. It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
