The air is mixed, so that the air blown out is softer.

The structure of the drive mechanism will be described in detail below.

Please refer to FIG. 4 , FIG. 5 and FIG. 6 , the driving mechanism includes a base 20 and a movable plate 20d , and the movable plate 20d is installed on the base 20 so as to be slidable up and down. The number of movable plates 20d may be one or two. The base 20 may be a whole (the base 20 may extend in the length direction of the panel 10b, or the size may be substantially the same as that of the movable panel 20d), or the base 20 may include two separate parts. In this way, the installation relationship between the movable plate 20d and the base 20 can be that one movable plate 20d is installed on an integral base 20 (for the case that the base 20 extends along the length direction of the panel 10b, the movable plate 20d can be installed in the middle of the base 20 ) For the case that the size of the base 20 is roughly the same as that of the movable plate 20d, the base 20 can be installed in the middle position of the panel 10b or the frame 10a); At the end, two movable panels 20d are arranged at intervals in the length direction of the panel 10b.

In the following content, the two movable plates 20d are mainly installed at both ends of the base 20 in the longitudinal direction as an example for introduction.

7, 8, 9 and 10, the movable plate 20d is provided with a guide rail 20f, the guide rail 20f is detachably fixed on the movable plate 20d, and one end of the guide rail 20f is connected to the movable plate 20d is inserted or buckled, and the other end is fixed on the movable plate 20d by screws (so it is convenient for the installation and removal of the guide rail 20f). The base 20 is provided with a guide chute 224 ( FIG. 9 and FIG. 10 ), and the guide rail 20f is adapted to the guide chute 224 , so that the movable plate 20d is relative to the base 20 through the cooperation of the guide rail 20f and the guide chute 224 Swipe up and down. It should be noted that, in the indoor unit of the air conditioner, no drive source may be provided in the drive mechanism, that is, the user may manually operate the windshield assembly 30 to move up and down. A drive source may also be provided in the drive mechanism, and by controlling the drive source, the windshield assembly 30 can be automatically raised and lowered.

Please continue to refer to FIG. 6 and FIG. 7 , the basic structure of the base 20 is as follows: it includes a base 20a and two side wings 20b, the two side wings 20b are respectively arranged at two ends of the base 20a, and the base 20a has a base 20a extending from one end to the other end. The first side 201 and the two side wings 20b protrude from the first side 201 (the base 20a and the side wings 20b may be integrally formed or connected by connecting pieces), so that in the indoor unit of the air conditioner, the entire base 20 may be approximately an inverted U-shaped structure.

Due to the limited space between the panel 10b and the face frame 10a in the air conditioner indoor unit, both the windshield assembly 30 and the base 20a have a certain thickness. Between the face frames 10a, at the beginning of the design, a large gap needs to be reserved between the face plate 10b and the face frame 10a, which will affect the overall shape of the air conditioner indoor unit (the overall air conditioner indoor unit appears thick). In addition, the width of the air outlet 101 is generally about 15 cm, so the width of the wind shield assembly 30 is generally designed according to the width of the air outlet 101, and its width is not much different from that of the air outlet 101, and the width of the entire panel 10b is relatively large, so even if the shield is blocked The wind assembly 30 and the base 20 are stacked. When the wind shield assembly 30 is accommodated inside the panel 10b, the large space left before the panel 10b and the frame 10a is not used, which also leads to a waste of space.

Therefore, after the base 20 is set to an inverted U-shaped structure, the windshield assembly 30 can be set at the middle gap of the inverted U-shaped structure, thereby greatly improving the space utilization rate between the panel 10b and the face frame 10a.

11 and 12, the base 20 further includes a motor box 20c mounted on the side wings 20b. The motor box 20c is detachably fixed to the side wings 20b, so that the installation and removal of the motor box 20c is convenient. The motor box 20c itself is formed with a concave portion 222 for accommodating the stepping motor 220a, a groove 211 for accommodating the concave portion 222 is formed on the side wing 20b, an insertion hole 214 is provided on the side wing 20b, and one end of the motor box 20c is provided with a lug 225a, the other end of the motor box 20c is fixed on the side wing 20b through a connecting piece. As shown in FIGS. 11 and 12 , the other end of the motor box 20c is provided with a screw hole 225b and a positioning hole 225c. For the positioning post 216, when the motor box 20c is installed on the side wing 20b, first insert the lug 225a into the insertion hole 214, and then place the recessed portion 222 into the groove 211 step by step, and then fit the positioning hole 225c and the positioning post 216 into place. After mating and plugging, finally insert the screw into the screw hole 225b and screw it into the screw column 215, so as to realize the installation of the motor box 20c. After the motor box 20c is installed on the side wing 20b, on the one hand, both ends of the motor box 20c are fixed.

7, 11 and 12, a stepping motor 220a and a first gear 221a are installed in the motor box 20c. The stepping motor 220a is fixed in the recess 222 of the motor box 20c by screws, and the first gear 221a is Mounted on the motor shaft of the stepping motor 220a. The motor box 20c is provided with a first wiring slot 223, the lugs 225a and the insertion hole 214 of the motor box 20c are located in the extending direction of the first wiring slot 223, and the slot of the first wiring slot 223 is provided with a first wiring slot. In the line clip 226, the wire 20g connected to the stepper motor 220a is inserted into the first wire slot 223, and under the limiting action of the first wire clip 226, the wire 20g is not easy to come out of the first wire slot 223.

Usually, a display module is set on the panel 10b, for example, parameters such as target temperature, air conditioner operating mode, humidity, etc. are displayed; and the positions of the display module and the driving mechanism are both inside the panel 10b, please refer to FIG. 13, in order to improve the air conditioner For the assembly efficiency of the indoor unit, the display module (the display module is not installed in the figure) can be integrated on the base 20, and the wire 20g connecting the stepping motor 220a can be connected to the display module, and then connected to the electric control box through the display module. The side wings 20b have a certain distance from the display module. Please continue to refer to FIG. 11 and FIG. 12. In order to prevent the wires 20g connecting the stepper motors 220a from being exposed from the first wiring slot 223, in one embodiment, the base 20a is provided with There is a second wiring slot 202, the second wiring slot 202 extends from the side 20b toward the display box, and the wire 20g passes through the first wiring slot 223 and then enters the second wiring slot 202, and then penetrates into the display box. Since the first wiring slot 223 extends in the up-down direction, and the second wiring slot 202 extends in the left-right direction, if the wire 20g is drawn out from the first wiring slot 223 and directly enters the second wiring slot 202, the Influenced by the second wiring slot 202, the wire 20g will be offset in the direction of the second wiring slot 202 in the first wiring slot 223. After a long time, the wire 20g may come out of the first wiring slot 223. Furthermore, the wire 20g may be pulled out from the second wire routing slot 202 . In view of this, in one embodiment, the base 20 a is provided with a wire hole 203 , and the wire hole 203 is located between the first wire groove 223 and the second wire groove 202 . In this way, the wire passage hole 203 is relatively close to the first wire routing slot 223 , which can reduce the deflection force of the wire 20g detaching from the first wire routing slot 223 . Further, since there is also a certain distance between the wire hole 203 and the first wire groove 223, if the distance is too long, the wire 20g will appear redundant here, and the redundant wire 20g will pass through the wire hole 203 and the second wire. The wire ducts 202 fall downward, and may eventually fall to the notch of the inverted U-shaped base 20, thereby interfering with the up and down sliding of the windshield assembly 30, and even causing a safety accident; on the other hand, the wire 20g It may also fall from below the panel 10b to the air outlet 101, thereby seriously affecting the user experience. In order to avoid this situation, in another embodiment, a pressure plate 204 is further provided on the base 20a, and the pressure plate 204 is located between the wire hole 203 and the second wire groove 202. The lower end is connected to the base 20a and extends upward. The arrangement of the crimping plate 204 can, on the one hand, crimp the wire 20g on the base 20a, and on the other hand, can also play a bearing role on the wire 20g, so that even if the wire 20g is slightly redundant, it will not fall into the gap of the base 20 place.

For the second wiring slot 202, its main function is to accommodate and hide the wires 20g. In one embodiment, in order to facilitate the installation of the wires 20g in the second wiring slot 202, the notch of the second wiring slot 202 faces the panel 10b, and a second line card 205 is disposed at the slot of the second wiring slot 202. The second wiring slot 202 has two side walls extending in the left-right direction, the second line card 205 is connected to one side wall, and the other side wall is provided with an escape notch 206 corresponding to the second line card 205 . During wiring, the second line card 205 is bypassed by avoiding the notch 206 , so that it is convenient for both wiring and removing the wire 20g from the second wiring groove 202 .

Among the two lateral wings 20b of the base 20, the notch of the first wire routing groove 223 on one of the lateral wings 20b is facing the other lateral wing 20b, so that it is convenient to hide the wires 20g, whether the user is from the front side or the back side When the base 20 was observed, the lead wire 20g was not seen.

In addition, the motor box 20c is slidably matched with the guide rail 20f. The motor box 20c is provided with the above-mentioned guide slot 224. The opening direction of the guide slot 224 is opposite to the opening direction of the first wire slot 223. The chute 224 is laterally open (in the indoor unit of the air conditioner, the opening of the guide chute 224 is left or right), so the guide chute 224 has a limiting effect on the guide rail 20f and can limit the guide rail 20f Displacement occurs forward or backward. Since both the guide rail 20f and the guide slot 224 extend in the up-down direction, after the guide rail 20f is matched with the guide slot 224, the guide rail 20f is in the guide slot 224. Swipe up and down only.

Please continue to refer to FIG. 7 to FIG. 10 , the guide rail 20f is provided with a rack, which meshes with the first gear 221a. When the stepping motor 220a is working, the first gear 221a can drive the guide rail 20f to move up and down . Please also refer to FIG. 18 , the guide rail 20f includes a rack plate 241 and a track plate 242 , a gap is formed between the rack plate 241 and the track plate 242 , and the rack plate 241 is provided with teeth that engage with the first gear 221 a The rail plate 242 is inserted into the guide chute 224. In order to make the sliding cooperation resistance between the guide rail 20f and the guide chute 224 smaller, the rail plate 242 is provided with a plurality of first columnar bodies 243. One side wall of the body 243 protrudes from one side of the track plate 242 , and the other side wall protrudes from the other side of the track plate 242 . In this way, when the track plate 242 is inserted into the guide chute 224 , the first columnar body 243 The side wall of the guide rail 20f is in contact with the inner wall of the guide chute 224, so that the frictional force is smaller, and the sliding of the guide rail 20f and the guide chute 224 is smoother.

The up and down movement of the movable plate 20d can be realized by one guide rail 20f matched with one guide groove 224 , or two guide rails 20f matched with two guide grooves 224 . Considering that the panel 10b of the wall-mounted air conditioner indoor unit extends in the left-right direction, in order to make the windshield assembly 30 slide more smoothly, guide rails 20f are provided on both movable panels 20d, and guide rails 20f are provided on both side wings 20b The guide chute 224 is a preferred embodiment. In addition, the two side wings 20b are also provided with sliding drive assemblies.

Please refer to FIGS. 6 , 14 and 15 , in order to make the windshield assembly 30 slide more smoothly, in a preferred embodiment, a deflection rectifying guide rail 20e is provided on the base 20 , and a deflection rectifying guide rail 20e is provided on the movable plate 20d to slide properly. The matching guide groove 251a. There may be one or two guiding guide rails 20e. The main function of the deviation-correcting guide rail 20e is to improve the sliding stability of the single movable plate 20d. The deviation-correcting guide rail 20e extends in the up-down direction, and the deviation-correcting guide rail 20e and the guide slide rail 20f are arranged at intervals. For the embodiment in which only one deviation-correcting guide rail 20e is installed on the base 20, the installation positions of the deviation-correcting guide rail 20e can be various. It is the deflection guide rail 20e located between the two guide rails 20f. For the implementation of installing two deviation-correcting guide rails 20e on the base 20, there are also various ways of installing the deviation-correcting guide rails 20e. For example, the two deviation-correcting guide rails 20e are both located between the two guiding slide rails 20f, or the deviation-correcting guide rails 20e and the guide rails 20f can be installed. The slide rails 20f are alternately arranged, and two guide slide rails 20f may also be located between the two deviation correction guide rails 20e.

The following contents mainly describe the installation of the deviation-correcting guide rail 20e.

Considering that when the windshield group is connected to the movable panel 20d, it is mainly connected to the inner side of the movable panel 20d (near the middle notch position of the inverted U-shaped base 20), so the inner side of the movable panel 20d needs to bear the gravity of the windshield assembly 30, while the movable panel 20d needs to bear the gravity of the windshield assembly 30. The outer side has a tendency to incline to the inner side.

The windshield assembly 30 itself extends along the length direction of the panel 10b (the windshield assembly 30 is used to block the air outlet 101, and the air outlet 101 extends in the left-right direction), and the windshield assembly 30 is relatively long (0.6m to 1m). left and right), there is a certain tolerance in the installation of such a length of the windshield assembly 30 on the movable plate 20d, and the base 20 and the movable plate 20d are plastic parts, so when the movable plate 20d moves in the up and down direction, once the two parts of the windshield assembly 30 If the end strokes are inconsistent (one end is high and one end is low), the movable plate 20d will be stuck, and the wind shield assembly 30 will not be able to move up and down.

On the one hand, the setting of the guide rail 20e provides more tracks for the movement of the windshield assembly 30, so that the movement of the windshield assembly 30 is more stable. When moving, the guide rail 20f and the deflection guide rail 20e are mutually restrained, so that the left and right swing of the movable plate 20d can be reduced, thereby reducing the problem of inconsistent strokes at both ends when the windshield assembly 30 moves up and down.

(sliding up and down along the side plate 212), the movable plate 20d is provided with a guide groove 251a, and the guide groove 251a is slidably matched with the deviation correction ribs 232a. In the guide rail 20f, the deflection correcting rib 232a is located on the side of the deflection correcting chute 231a facing away from the guide rail 20f of the side wing 20b. In this way, in the front-rear direction, the guide grooves 251a can hold and limit the deflection correcting ribs 232a.

In addition, in order to facilitate the disassembly and assembly of the deviation-correcting chute 231a, the deviation-correcting chute 231a may be fixed to the side wing 20b in a detachable manner. In one embodiment, the side plate 212 is provided with a fixing hole 212a, and the inner groove wall of the deviation correction chute 231a is provided with a clamping table 236 corresponding to the position of the fixing hole 212a. In this way, after the clamping table 236 is inserted into the fixing hole 212a during the installation of the deviation-correcting guide rail 20e, the deviation-correcting chute 231a can be firmly fixed on the side plate 212 (in the up-down direction, the deviation-correcting chute 231a and the side plate 212 can remain relatively fixed relative to each other ). In order to make the installation of the guide rail 20e more stable, the side wing 20b is provided with a first fixing groove 212b (located at the lower end of the side plate 20b, in the shape of a notch) located on the inner side of the side plate 212. One side is provided with a first buckling platform 234 for buckling the side plate 212, and the other side is provided with a second buckling platform 235 matched with the first fixing groove 212b. In this way, the first buckle platform 234 can buckle one side of the side plate 212, so as to keep one side wall of the deviation correction chute 231a relatively fixed to the side plate 212, and the second buckle platform 235 can fasten the other side wall of the deviation correction chute 231a. Fixed on the side plate 212 . Further, please continue to refer to FIG. 14 , the first side 201 of the base 20 a is provided with a stopper 213 , a second fixing slot 213 a is formed between the stopper 213 and the side plate 212 , and the deviation correction chute 231a is inserted into the The second fixing groove 213a. In order to facilitate the assembly of the deviation-correcting guide rail 20e, the clamping table 236 and the second locking table 235 are disposed at one end of the deviation-correcting chute 231a away from the base 20a.

Further, please refer to FIG. 15 , in order to facilitate the installation and removal of the deviation correction chute 231a, the above-mentioned clamping table 236 is arranged in a triangular shape. That is, when the upper port of the deviation-correcting chute 231a is aligned with the lower end of the side plate 212, the deviation-correcting chute 231a is pushed upward, and the first buckle platform 234 is buckled with one side of the side plate 212. When the lower end of the cam is abutted, continue to push the correction chute 231a upwards and forcefully. At this time, since the clamping table 236 is arranged in a triangular shape, one side of the clamping table 236 is an inclined plane. Under the guiding action of the inclined plane, the clamping table 236 gradually passes over the side plate. 212, and under the abutting action of the clamping table 236 and the side plate 212, the side plate 212 and/or the deviation correction guide rail 20e are deformed until the clamping table 236 is snapped into the fixing hole 212a, the side plate 212 and/or the deviation correction guide rail 20e. 20e recovers the deformation, so that the groove bottom of the deflection correcting chute 231a can be firmly attached to the side plate 212 . To sum up, the deviation correction chute 231a is fixed in four ways (the upper end of the deviation correction chute 231a is inserted into the second fixing slot 213a, the first buckle platform 234 is buckled with the side plate 212, the second buckle platform 235 is connected with the first fixing slot 212b is buckled, and the clamping table 236 is snapped into the fixing hole 212a) to firmly fix the deviation-correcting guide rail 20e on the side plate 212.

Please continue to refer to FIG. 14 and FIG. 15 , the rectifying rib 232a is roughly flush with one side of the rectifying chute 231a, and the rectifying rib 232a is snapped into the guide groove 251a, in order to reduce the friction between the rectifying rib 232a and the inner wall of the guide groove 251a A plurality of second columnar bodies 233 are arranged on the deviation-correcting rib 232a, that is, the guide groove 251a has two opposite side walls, and at least two arc-surface protrusions 233a ( The cambered protrusions 233a are the sidewalls of the second cylindrical body 233 ), and the cambered protrusions 233a located on both sides of the deflection rectifying guide rail 20e abut against the two sidewalls of the guide groove 251a respectively.

The structures of the two rectifying guide rails 20e may be the same or different. In another embodiment, please refer to FIG. 16 and FIG. 17 , the deviation-correcting guide rail 20e includes a deviation-correcting chute 231b, the movable plate 20d is provided with a guide portion 251b, and the guide portion is provided on the inner side of the side wings 20b (approximately located in the same direction as the base). At the junction of 20a, the base 20a and the side wings 20b may not have an obvious junction line, and the two may be integrally formed or of course assembled).

Referring to FIG. 17 , in order to further reduce the frictional resistance between the deviation correction chute 231b and the guide portion 251b, the deviation correction guide rail 20e further includes a deviation correction convex rib 232b disposed on the inner wall of the deviation correction chute 231b, and the deviation correction convex rib 232b abuts against the guide portion 251b The deflection-correcting protruding rib 231b extends in the up-down direction, the contact area between it and the guide portion 251b is small, and the sliding is smoother.

Since the deviation-correcting guide rail 20e needs to ensure the sliding track of the movable plate 20d, the material of the deviation-correcting guide rail 20e can be set to a rigid material, such as stainless steel, aluminum alloy, etc.; The deviation-correcting guide rail 20e slides more smoothly, and the material of the deviation-correcting guide rail 20e can be made of self-lubricating wear-resistant material.

When the wind shielding assembly 30 is a swirl module, the wind blades 301 provided in the wind shielding assembly 30 can be rotated by means of active driving. In one embodiment, one of the movable plates 20d is further provided with a fan blade 301 driving assembly, and the fan blade 301 driving assembly is connected to the fan blade 301 for driving the fan blade 301 to rotate. The driving assembly of the fan blade 301 includes a driving motor 220b and a second gear 221b, and the second gear 221b is drivingly connected with the fan blade 301 .

Please refer to Fig. 11, Fig. 12 and Fig. 18, the movable plate 20d moves up and down, the drive assembly of the fan blade 301 moves together with the movable plate 20d, and the motor wire 20g connected to the driving motor 220b also moves together, so the motor wire 20g requires a certain length of redundancy. The base 20 is provided with a wire slot 227 for wiring the motor wire 20g. The motor wire 20g passes through the wire inlet 228 of the wire slot 227 and penetrates into the wire slot 227, and then connects to the display box. The upper and lower directions are roughly at a 90° angle, so after the redundant motor wire 20g is drawn out from the wire inlet 228, it is easy to bend at a large angle during the movement process. If this is the case for a long time, the motor wire 20g is easily fatigued and damaged. . One affects the operation of the windshield assembly 30 , the other reduces the service life of the indoor unit of the air conditioner, and the other is likely to cause safety accidents.

In addition, the closer the distance between the wire slot 227 and the drive motor 220b is, the easier the motor wire 20g between them is to bend at a large angle. Therefore, the wire slot 227 and the drive motor 220b should be aligned in the length direction of the panel 10b. The interval is maintained, and the longer the interval, the less likely the motor wire 20g is to be bent at a large angle.

In one embodiment, please refer to FIG. 19 to FIG. 21 , in order to prevent the redundant motor wire 20g from being bent at a large angle, the wire inlet 228 of the wire passage slot 227 is provided with a first guide portion 229 . The portion 229 can extend obliquely upward from the wire inlet 228, or can extend obliquely downward from the wire inlet 228. The above-mentioned sloping extension can be inclined along a straight line or inclined along an arc. If the first guide portion 229 extends obliquely downward from the wire inlet 228, when the movable plate 20d moves downward, the first guide portion 229 has a certain bearing capacity for the motor wire 20g, and can also lower the motor wire 20g is the bending angle at the end of the first guide portion 229. If the first guide portion 229 extends upward from the wire inlet 228 slantingly, then when the movable plate 20d moves upward, under the action of the first guide portion 229, the motor wire 20g is drawn out from the wire inlet 228 and received Under the guidance of the first guide portion 229 and the action of the self-gravity of the motor wire 20g, the motor wire 20g will not be bent too much.

If there is only one first guide portion 229 above, a preferred arrangement is to extend the first guide portion 229 obliquely downward from the wire inlet 228 .

Considering that the guiding effect of a single first guiding part 229 is not as good as that of two first guiding parts 229, in one embodiment, two first guiding parts 229 are provided at the wire inlet 228, One of the first guide portions 229 is bent downward from the wire inlet 228 , and the other first guide portion 229 is bent upward from the wire inlet 228 . In this way, whether the movable plate 20d moves upward or downward, the first guide portion 229 can guide the redundant motor, thereby preventing the motor wire 20g from being bent too large.

In addition, the length s1 of the first guide portion 229 extending downward from the wire inlet 228 is defined, and the length of the first guiding portion 229 extending upward from the wire inlet 228 is defined as s2, and s1 is preferably greater than s2. This is because the motor wire 20g will be subjected to its own action when moving, and when the motor wire 20g contacts the end of the first guide portion 229 extending downward, it is more likely to bend at a large angle. The length of 229 itself is lengthened, and the tangent of the end of the first guide portion 229 may coincide (or substantially coincide) with the extending direction of the motor wire 20g, so that the wire 20g extends more smoothly after passing through the first guide portion 229 .

In another preferred embodiment, in order to make the guiding effect of the two first guiding parts 229 better, a gap is formed between the two first guiding parts 229 . The direction is flared. On the one hand, the two first guide portions 229 are arranged in an arc shape, and the gap between the two is arranged in a flared manner, so that the angle between the tangent lines of the two first guide portions 229 will also follow the distance away from the wire inlet 228 . The direction is getting bigger and bigger, which can also reduce the large-angle bending of the motor wire 20g.

The large-angle bending of the motor wire 20g depends not only on the position of the wire inlet 228, but also on the wire outlet angle of the driving motor 220b itself. In one embodiment, the movable plate 20d is provided with a second guide portion 261, the second guide portion 261 is located at the periphery of the driving motor 220b, and the second guide portion 261 faces the side where the wire slot 227 is located and downwards It extends obliquely, or the second guide portion 261 faces the side where the wire-passing groove 227 is located and extends obliquely upward.

Of course, similar to the case of the first guide portion 229 , it is preferable to provide two second guide portions 261 . That is, the movable plate 20d is provided with two second guide parts 261, the two second guide parts 261 are spaced apart, one of the second guide parts 261 is bent downward, and the other second guide part 261 is upward. bending. The bending effect of the second guide part 261 can refer to the first guide part 229 .

In addition, since the motor wire 20g is usually welded with the motor interface, if the motor wire 20g is connected to the motor interface by pulling force, the solder joints at the interface will be loosened, and the drive motor 220b will be in poor contact. In severe cases, the motor wire will be directly caused 20g is disengaged from the motor. In view of this, in an embodiment, a wire winding portion 262 is disposed between the two second guide portions 261 , and the wire winding portion 262 is spaced apart from the two second guide portions 261 . After the winding portion 262 is provided, the motor wire 20g can be laid on the winding portion 262. Even if a pulling force is applied, the motor wire 20g can disperse most of the pulling force to the winding portion 262, thereby avoiding the connection between the motor wire 20g and the motor interface. Solder joints are loose.

There are various ways to route the motor wire 20g between the two second guide portions 261. For example, the gap between the wire winding portion 262 and a second guide portion 261 close to the driving motor 220b is defined as gap 1, and the winding portion 262 is defined as gap 1. The gap between the wire portion 262 and the other second guide portion 261 is defined as the gap 2. After the motor wire 20g is drawn out from the driving motor 220b, it first passes through the gap 1, then passes through the gap 2, and is then guided by the two first guides. The gap between the lead portions 229 enters the wire inlet 228 . It is also possible that after the motor wire 20g is drawn out from the motor, it first passes through the second gap, then passes through the first gap, and then enters the wire inlet 228 through the gap between the two first guiding parts 229 . That is, the motor wire 20g connected to the driving motor 220b is wound around the outer circumference of the winding portion 262 and enters the wire slot 227 through the gap between the two first guide portions 229 . For this way of winding one round, if the motor wire 20g suddenly receives a large pulling force when the movable plate 20d moves up and down, the pulling force can almost be transferred to the winding portion 262 in an instant. Therefore, the winding portion The 262 setting provides excellent protection for the motor wire 20g connection.

For the embodiment without the wire winding portion 262 , the wire winding method can also be such that after the motor wire 20g is drawn out from the motor, it surrounds the outer circumference of the driving motor 220b and passes through the gap between the two second guide portions 261 . , and the gap between the two first guide portions 229 enters the wire slot 227 . That is, the outer wall of the driving motor 220b replaces the function of the above-mentioned winding portion 262. When the motor wire 20g is subjected to a sudden pulling force, the pulling force can be instantaneously caused by the friction force generated between the driving motor 220b and the motor wire 20g. to offset, so as to protect the connection of the motor wire 20g.

The movable plate 20d has two extreme positions that move to the uppermost and the lowermost position, the travel between the two extreme positions is the maximum travel of the movable plate 20d, and the redundant motor wire 20g between the wire inlet 228 and the winding portion 262 The length must always be greater than the straight-line distance between the wire inlet 228 and the wire winding portion 262 , otherwise the motor wire 20g will be severely pulled during the movement of the movable plate 20d up and down. In addition, the redundant motor wire 20g between the wire inlet 228 and the winding part 262 should not be too long, because the excessively long motor wire 20g will be twisted and knotted between the wire inlet 228 and the winding part 262, so it is easy to Premature fatigue damage to the motor wire 20g. Therefore, the best way is that the length of the motor wire 20g from the wire inlet 228 to the winding part 262 is slightly larger than the straight line distance between the wire inlet 228 and the winding part 262, for example, the wire inlet 228 to the winding part The linear distance between the parts 262 is L1, the length of the motor wire 20g between the wire inlet 228 and the winding part 262 is L2, 1.1×L1≤L2≤1.3×L2. Of course, since the movable plate 20d has two extreme positions, upper and lower, in order to satisfy both the upper and lower extreme positions of the movable plate 20d, the length of the motor wire 20g between the wire inlet 228 and the winding portion 262 is just slightly larger than The straight line distance between the wire inlet 228 and the winding portion 262, in this embodiment, the wire inlet 228 can be set in the middle of the maximum stroke of the movable plate 20d, that is, the wire inlet 228 is in the maximum stroke of the movable plate 20d. Roughly centered above.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the description and drawings of the present invention, or directly/indirectly applied to other All relevant technical fields are included in the scope of patent protection of the present invention.
