The front lock assembly with the structure is internally surrounded by the front cover body 300 and the first casing 220 to form a columnar accommodating space, the electric clutch mechanism 500 and the plurality of dry batteries are circumferentially arranged in the accommodating space at intervals around the shaft sleeve part 210, the electric clutch mechanism 500 and the dry batteries are all arranged in an extending manner along the length direction of the accommodating space, the first clutch part 510 extends out of the end part of the dry batteries to be combined with or separated from the connecting rod 400, the inner space of the front lock assembly is fully utilized through ingenious space layout and structural design, and the electric unlocking mechanism and the dry batteries are concentrated in the front lock assembly on the premise of not increasing the original shape and size, and the using hand feeling of a user is prevented from being influenced; compared with the traditional front lock assembly with an integrated shell part, the soft package battery is not convenient to detach and replace, and the soft package battery is usually fixed in a circuit in a soldering tin mode, so that the soft package battery is difficult to replace.
It can be appreciated that when the electric clutch mechanism 500 receives an instruction to drive the first clutch member 510 to be combined with the connecting rod 400, the front handle sleeve 200 rotates relative to the fixing seat 100 by using the shaft sleeve portion 210 to drive the connecting rod 400, so that the connecting rod 400 drives the latch bolt assembly to unlock, and the front lock assembly can be normally rotated to open and close the lock while the plurality of dry batteries are arranged in the front lock assembly, and the dry batteries are convenient to install and replace. In addition, because the dry battery and the electric clutch mechanism 500 are arranged in the front lock assembly, the problem that the electric wire between the storage battery and the electric clutch mechanism 500 is difficult to connect and install due to the fact that the storage battery is arranged in the rear ball lock body is solved, the problem that the electric wire is twisted when the front lock assembly or the rear lock assembly is rotated is solved, and the electric conduction stability is ensured.
Referring to fig. 2,3 and 5, in some embodiments of the present invention, a battery compartment 700 is installed in the accommodating space, four battery channels 710 for accommodating dry batteries and an installation position for accommodating the electric clutch mechanism 500 are circumferentially arranged around the axial direction of the shaft sleeve portion 210, the first clutch member 510 is a latch member which is parallel to the axial direction of the shaft sleeve portion 210 and reciprocally moves and faces the installation position, one end of the connecting rod 400 extending into the first casing 220 is provided with a combining member 410, the combining member 410 is provided with a plug hole 411 matched with the latch member, when the electric clutch mechanism 500 drives the latch member to extend, the latch member can enter the plug hole 411 to unlock, and when the latch member retracts, the latch member leaves the plug hole 411 to lock. It will be appreciated that each of the dry batteries is disposed through the corresponding battery channel 710 to ensure that the position of the dry battery is stable, thereby ensuring that the electric clutch mechanism 500 can be stably powered. The overall length dimension range of the electric clutch mechanism 500 located on the installation position and the length dimension range of the dry battery have a large number of overlapping parts, that is, the electric clutch mechanism 500 only has the bolt member extending out of the end of the dry battery, so that the length dimension of the front lock assembly is not increased, the use feeling of a user is maintained to a certain extent, and good holding feeling is maintained.
Referring to fig. 2 to 4, in some embodiments of the present invention, the electric clutch mechanism 500 includes a motor 520 fixed at an installation position, a latch member is provided with a limit slot 511 extending parallel to the shaft sleeve portion 210, an output shaft of the motor 520 movably passes through the limit slot 511, a spring member 530 disposed in the limit slot 511 is disposed on an output shaft of the motor 520 in a penetrating manner, two ends of the spring member 530 respectively abut against inner walls of two opposite sides of the limit slot 511 in a length direction, a transmission pin 521 disposed between two adjacent turns of the spring member 530 is disposed on an output shaft of the motor 520, and the latch member is driven to move toward the plug hole 411 in a telescopic manner by the spring member 530 when the motor 520 rotates positively and negatively. Specifically, when the motor 520 drives the driving pin 521 to rotate, the spring member 530 moves axially along the output shaft of the motor 520, the number of turns of the spring coil located on one side of the driving pin 521 increases, and the latch member moves in a direction in which the number of turns of the spring coil increases, thereby realizing the movement of inserting the latch member into the insertion hole 411 or retracting from the insertion hole 411. It will be readily appreciated that the motion mechanism formed by the output shaft of the motor 520, the drive pin 521 and the spring member 530 corresponds to a lead screw nut mechanism, and that the drive pin 521 is always located between two of the turns of the spring member 530 during rotation of the output shaft of the motor 520.
As a preferred embodiment of the present invention, the coupling member 410 is located at the connection portion between the boss 210 and the first casing 220, so as to avoid occupying more space in the length direction of the front handle sleeve 200, the limiting groove 511 and the motor 520 are both located within the length range of the battery compartment 700, a portion of the latch member extends out of the end surface of the battery compartment 700 and is matched with the coupling member 410, and a portion of the latch member extending out of the end surface of the battery compartment 700 is located at the outer peripheral position of the coupling member 410, so that the occupied space in the length direction of the front handle sleeve 200 is not further increased, and most of the space in the length direction of the front handle sleeve 200 is reserved for the battery compartment 700, which is beneficial to making the structure in the length direction of the front lock ball more compact.
Referring to fig. 2 to 5, in some embodiments of the present invention, in order to enrich the unlocking mode to avoid the problem that the electric clutch mechanism 500 fails and cannot be unlocked, a mechanical lock cylinder 800 is installed in the middle of the battery compartment 700, in order to fully utilize the space of the battery compartment 700 for reasonable use, four battery channels 710 and the electric clutch mechanism 500 are arranged around the mechanical lock cylinder 800, a key hole of the mechanical lock cylinder 800 is exposed at one end of the battery compartment 700 near the front cover 300, a side pushing part 512 opposite to an output end of the mechanical lock cylinder 800 is provided at a side of the latch member, and the output end of the mechanical lock cylinder 800 can extend out of the other end of the battery compartment 700 to push the side pushing part 512 to move so that the latch member is inserted into the insertion hole 411. It can be understood that when the front cover 300 moves relative to the front handle sleeve 200 to open the opening of the first accommodating cavity 221, the keyhole of the mechanical lock cylinder 800 is exposed, a user can insert a key into the keyhole and rotate the mechanical lock cylinder 800, the output end of the mechanical lock cylinder 800 can extend toward the direction of the combining member 410 to push the side pushing portion 512 to move, thereby driving the latch member to insert into the inserting hole 411, and then the front lock assembly can drive the connecting rod 400 to rotate together to unlock when rotating.
Referring to fig. 3 and 5, in some embodiments of the present invention, the mounting position includes a long bottom plate 720 formed on the battery compartment 700 and two arc clamping plates 730 formed on opposite sides of the long bottom plate 720, a mounting groove for preventing the motor 520 from rotating relative to the battery compartment 700 is defined between the long bottom plate 720 and the two arc clamping plates 730, the latch member has a sliding block portion slidably disposed in the mounting groove, the limiting groove 511 is formed in the sliding block portion, and the long bottom plate 720 is provided with a relief hole 721 for the side pushing portion 512 to extend toward the mechanical lock cylinder 800. Specifically, the battery compartment 700 directly forms the battery channel 710, the long-strip bottom plate 720 and the arc-shaped clamping plate 730 in an integral injection molding mode, and the extending directions of the battery channel 710, the long-strip bottom plate 720 and the arc-shaped clamping plate 730 are consistent, so that the injection mold is simple in structure and low in cost, and is also beneficial to the production and manufacture of the battery compartment 700. The installation groove defined by the long bottom plate 720 and the two arc clamping plates 730 forms the installation position, and the installation groove is used for accommodating the motor 520 and for allowing the sliding block part to slide reciprocally so as to combine or separate the latch member and the combining member 410, thereby achieving the effect of one object for two purposes.
Referring to fig. 2 and 3, in some embodiments of the present invention, a first power receiving plate 610 is disposed at one end of the battery compartment 700 near the fixing base 100 and is abutted against one end of the dry battery, the other end of the dry battery extends out of the battery compartment 700 to enter the front cover 300, a second power receiving plate 620 is disposed in the front cover 300 and is abutted against one end of the dry battery far from the fixing base 100, and the first power receiving plate 610 and the second power receiving plate 620 are respectively contacted with the positive electrode and the negative electrode of the dry battery, so that connection between a plurality of dry batteries can be also achieved. It will be appreciated that the majority of the dry battery along its length is located within the battery compartment 700 and the minority of the dry battery along its length is located within the front cover 300, making full use of the receiving space and avoiding unnecessarily increasing the length dimension of the front lock assembly.

It can be understood that when the dry battery needs to be replaced, since a part of the dry battery extends into the front cover 300, the direct drive shaft 321 collides with the dry battery when rotating relative to the shaft hole 741, the opening of the first cavity 221 cannot be completely opened, and the second power receiving plate 620 rubs against the positive electrode or the negative electrode of the dry battery. When the front lock assembly with the structure is adopted, the rotating shaft portion 321 can move along the shaft hole portion 741 away from the battery compartment 700 to a certain gap between the front cover body 300 and the end portion of the dry battery, at this time, the front cover body 300 is rotated again to completely open the opening of the first accommodating cavity 221, and on the premise that the length size of the front lock assembly is matched with the length size of the dry battery, the convenient replacement of the dry battery can be realized.
Referring to fig. 1 to 3, in some embodiments of the present invention, the first casing 220 includes a cylindrical sleeve 222 and a first circular arc sleeve 223 formed at one end of the cylindrical sleeve 222, the boss 210 is formed at the other end of the cylindrical sleeve 222, the radial dimension of the first circular arc sleeve 223 is larger than that of the cylindrical sleeve 222, the front cover 300 includes a second circular arc sleeve 310 capable of being spliced with the first circular arc sleeve 223 to form a spherical surface, the outer circumferential wall of the battery compartment 700 abuts against the inner circumferential wall of the cylindrical sleeve 222, the end surface of the battery compartment 700 adjacent to the front cover 300 is provided with a first end plate 740 protruding radially outwards, the shaft hole 741 is formed at the outer circumferential edge of the first end plate 740, the second circular arc sleeve 310 is provided with a second end plate 320 towards the opening edge of the first circular arc sleeve 223, the shaft 321 is formed at the outer circumferential edge of the second end plate 320, a second accommodating cavity is defined between the second end plate 320 and the second circular arc sleeve 310, the second connecting plate 620 is located within the second accommodating cavity, and the second end plate 320 is provided with a through hole 322 for passing the dry battery to abut against the second connecting plate 620. It will be appreciated that the first and second circular sleeves 223, 310 are spliced to form a spherical surface, and the feel of the user holding the front lock assembly is substantially identical to that of a conventional front ball lock, which is advantageous for maintaining a good feel. Since the dry battery is cylindrical, an annular inner space is further provided between the battery compartment 700 and the whole body formed by the first and second circular arc sleeves 223 and 310, and the annular inner space can just accommodate the first and second end plates 740 and 320, the rotating shaft 321 and the shaft hole 741, thereby perfectly utilizing the inner space of the front lock assembly. In addition, the through holes 322 of the second power receiving plate 620 also have a supporting effect on the dry cell, helping to align the second power receiving plate 620.
Referring to fig. 1 and 2, in this embodiment, a fingerprint recognition module connected to the electric clutch mechanism 500 is further disposed in the second cavity, and an input end of the fingerprint recognition module is exposed at a front end surface of the second circular arc sleeve 310, so as to facilitate a user to input fingerprint information.
Referring to fig. 2 and 4, in some embodiments of the present invention, a through hole portion is formed through the connecting rod 400 along the length direction thereof, a shift lever 420 capable of rotating relative to the through hole portion is formed through the through hole portion, one end of the shift lever 420 extends out of the connecting rod 400 and extends to the rear ball lock body, the other end of the shift lever 420 is provided with a shift block 430 extending into the first casing 220, at least two contact switches 611 are circumferentially distributed on the first power receiving plate 610 around the rod of the connecting rod 400, the electric clutch mechanism 500 has an operation mode corresponding to the contact switches 611 one by one, the contact switches 611 and the electric clutch mechanism 500 are connected with the control module, and the shift block 430 rotates along with the shift lever 420 to trigger one of the contact switches 611 so as to switch the electric clutch mechanism 500 to a certain operation mode. One end of the shift lever 420 extending to the rear ball lock body is provided with a knob member, and when the knob member is grasped by a user to rotate, the shift block 430 is driven to trigger one of the contact switches 611, so that the shift lever is switched to a working mode corresponding to the contact switch 611. The specific working mode is set according to actual needs, for example, when a user in a room wants to avoid the disturbance of other people except for a designated crowd, at the moment, the other people except for the designated crowd cannot start the electric clutch mechanism 500 even if common identity verification information is input, but the electric clutch mechanism 500 can be started to unlock after the identity verification information of the designated crowd is input, for example, when a single user or a plurality of users enter the room to perform related privacy behaviors, in order to obtain a use function with higher privacy degree, the rotatable shifting block 430 triggers the other contact switch 611, at the moment, the electric clutch mechanism 500 fails, and a person outside the room can only unlock the mechanical lock cylinder 800 by using a key, thereby not only playing a better privacy protection effect, but also retaining the unlocking function and guaranteeing the safety.
The invention also discloses an electric ball lock, which comprises the front lock component of any technical scheme. The electric ball lock fully utilizes the inner space of the front lock assembly through ingenious space layout and structural design, realizes that the electric unlocking mechanism and the dry battery are concentrated in the front lock assembly, and the original shape and the size of the front lock assembly are not changed to avoid influencing the use hand feeling of a user, and the replacement of the dry battery is very convenient, thereby solving the problem that the service life of the electric ball lock is influenced due to the short service life of the traditional soft package battery.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
