Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart lock technology, and in particular to an actuator for a smart lock. Background Technology
[0002] In the field of smart locks, the actuator is the core component that enables locking and unlocking functions. Its working principle typically involves receiving control signals to drive a pin into a hole in the rotating base to lock, or pulling the pin out of the hole to unlock.
[0003] Currently, the actuators of common smart locks on the market mainly consist of a housing and its internal drive components. To ensure the stable operation of the drive components within the housing, existing technologies generally use fasteners, such as bolts, to fix the drive components inside the housing. However, this fixing method has obvious drawbacks: on the one hand, during the assembly process, manual operation is required to tighten the bolts of each actuator component one by one, which is cumbersome and consumes a lot of time and labor costs. Utility Model Content
[0004] The purpose of this utility model is to provide an actuator for an intelligent lock, addressing the shortcomings and deficiencies of existing technologies.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] The present invention discloses an actuator for an intelligent lock, comprising an outer shell and an actuator power assembly fixed inside the outer shell; the outer shell consists of a bottom shell and a cover plate detachably connected to the bottom shell; the actuator power assembly includes a sliding plate, a pin slidably connected to the bottom shell, and a push-pull module for pushing the sliding plate to reciprocate; an annular groove is provided around the outer circular wall of the pin; a U-shaped retaining plate is provided on the sliding plate that engages with the annular groove; a limiting strip is provided on the sliding plate that protrudes upward; a support plate is provided on the bottom surface of the cover plate; the upper and lower surfaces of the sliding plate are respectively attached to the bottom end of the support plate and the inner bottom wall of the bottom shell; the two side surfaces of the limiting strip are respectively attached to the side surface of the bottom shell and the side surface of the support plate.
[0007] Furthermore, a push plate is fixed on the sliding plate; the push-pull module consists of a spring, a motor, and a disc; the motor is clamped between the bottom housing and the cover plate; the arc surface of the disc abuts against the surface of the push plate; the eccentric position of the disc is fixed on the output end of the motor; the two ends of the spring are respectively connected to the inner sidewalls of the sliding plate and the bottom housing.
[0008] Furthermore, reinforcing ribs are provided between the side surface of the push plate and the upper surface of the sliding plate.
[0009] Furthermore, a spring positioning sleeve is fixed on the push plate; one end of the spring is inserted into the spring positioning sleeve; the other end of the spring is pressed against the inner side wall of the bottom shell.
[0010] Furthermore, the front surface of the bottom housing is open; a front baffle is provided on the front surface of the cover plate; slots for sliding connection with the front baffle are provided on both the left and right sides of the bottom housing; the two sides of the front baffle are respectively inserted into the slots on both sides; a connecting sleeve is provided on the cover plate; a threaded hole is provided on the bottom housing; a bolt is threaded onto the threaded hole after passing through the connecting sleeve; a guide ring matching the pin is provided on the inner surface of the front baffle; the pin is inserted into the guide ring.
[0011] With the above structure, the beneficial effects of this utility model are as follows: Although the bottom surface and side surface of the support plate are in contact with the top and side surfaces of the sliding plate, the sliding plate is not pressed tightly onto the bottom shell. Therefore, the sliding plate can slide on the bottom shell. The support plate, the side surface of the bottom shell, and the inner bottom wall of the bottom shell form a guiding structure for the sliding plate. Combined with the U-shaped clamping plate being inserted into the annular groove, the sliding plate forms a structure on the bottom shell that can only slide horizontally. The sliding plate and the pin are connected by a snap-fit method, which is convenient for assembly. When the push-pull module is activated, the sliding plate can slide, and the pin can reciprocate. In this structure, the connection between the sliding plate and the pin and the connection between the sliding plate and the bottom shell do not require additional bolts for fixing, which is convenient for assembly and has high assembly efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings.
[0024] like Figures 1 to 5 As shown, the actuator of the intelligent lock according to this utility model includes an outer shell and an actuator power assembly fixed inside the outer shell. The outer shell consists of a bottom shell 4 and a cover plate 1 detachably connected to the bottom shell 4. The actuator power assembly includes a sliding plate 2, a pin 6 slidably connected to the bottom shell 4, and a push-pull module for pushing the sliding plate 2 to reciprocate. An annular groove 601 is provided around the outer circular wall of the pin 6. A U-shaped locking plate 201 is provided on the sliding plate 2, which is inserted into the annular groove 601. An upwardly protruding limiting strip 202 is provided on the sliding plate 2. A support plate 102 is provided on the bottom surface of the cover plate 1. The upper and lower surfaces of the sliding plate 2 are respectively attached to the bottom end of the support plate 102 and the inner bottom wall of the bottom shell 4. The two side surfaces of the limiting strip 202 are respectively attached to the side surface of the bottom shell 4 and the side surface of the support plate 102.
[0025] Although the bottom surface and side surface of the support plate 102 are in contact with the top and side surfaces of the sliding plate 2, the sliding plate 2 is not pressed tightly against the bottom housing 4. Therefore, the sliding plate 2 can slide on the bottom housing 4. The support plate 102, the side surface of the bottom housing 4, and the inner bottom wall of the bottom housing 4 form a guiding structure for the sliding plate 2. Combined with the U-shaped clamping plate 201 being inserted into the annular groove 601, the sliding plate 2 forms a structure on the bottom housing 4 that can only slide horizontally. The sliding plate 2 and the pin 6 are connected by a snap-fit method, which is convenient for assembly. When the push-pull module is activated, the sliding plate 2 can slide, which can realize the reciprocating motion of the pin 6.
[0026] In this structure, the connection between the sliding plate 2 and the pin 6, and the connection between the sliding plate 2 and the bottom housing 4, do not require additional bolts for fixing, making assembly convenient and efficient.
[0027] In a preferred embodiment of this utility model, a push plate 203 is fixed on the sliding plate 2; the push-pull module consists of a spring 3, a motor 5, and a disc 7; the motor 5 is clamped between the bottom housing 4 and the cover plate 1; the arc surface of the disc 7 abuts against the surface of the push plate 203; the eccentric position of the disc 7 is fixed on the output end of the motor 5; the two ends of the spring 3 are respectively connected to the inner sidewalls of the sliding plate 2 and the bottom housing 4.
[0028] A motor bracket 402 structure is fixed in the inner cavity of the bottom housing 4. The motor bracket 402 is not fundamentally different from the prior art, so it will not be described in detail. The bottom of the motor 5 matches the motor bracket 402. After the motor 5 is installed in the motor bracket 402, the motor 5 cannot move forward, backward or left or right, but can only be pulled out upward. Then the motor pressing block 103 presses the motor 5 down, so that the motor 5 cannot be pulled out upward, thereby fixing the motor 5 between the cover plate 1 and the bottom housing 4. The motor pressing block 103 is provided on the cover plate 1. During assembly, the motor 5 is first placed into the inner cavity of the motor bracket 402 and positioned. After the bottom housing 4 and the cover plate 1 are combined, the motor 5 and the disc 7 can be fixed between the bottom housing 4 and the cover plate 1. The force of the spring 3 keeps the surface of the push plate 203 pressed against the arc surface of the disc 7. The motor 5 drives the disc 7 to make an eccentric movement. When the rotation center of the push plate 203 and the disc 7 reaches its maximum value, the sliding plate 2 pulls the pin 6 into the bottom housing 4 to its maximum length. In this state, the pin 6 is pulled out from the rotating seat of the lock body and can be unlocked. Conversely, the motor 5 drives the disc 7 to reset, and the spring 3 pushes the pin 6 to reset through the sliding plate 2 and inserts it into the rotating seat to lock. Both sides of the outer circular wall of the disc 7 are provided with chamfered planes 701. In both states where the pin 6 is pulled into the bottom housing 4 to its maximum depth or when the pin 6 is extended to the bottom housing 4 to its maximum depth, the chamfered planes 701 are in contact with the surface of the push plate 203, so that the motor 5 does not need to be loaded in these two states.
[0029] As a preferred embodiment of the present invention, a reinforcing rib 20301 is provided between the side surface of the push plate 203 and the upper surface of the sliding plate 2.
[0030] In a preferred embodiment of this utility model, a spring positioning sleeve 204 is fixed on the push plate 203; one end of the spring 3 is inserted into the spring positioning sleeve 204; the other end of the spring 3 is pressed against the inner side wall of the bottom housing 4. The assembly of the spring 3 is carried out by inserting one end into the spring positioning sleeve 204, which improves the assembly efficiency.
[0031] In a preferred embodiment of this utility model, the front surface of the bottom housing 4 is open; a front baffle 104 is provided on the front surface of the cover plate 1; slots 403 that are slidably connected to the front baffle 104 are provided on both the left and right sides of the bottom housing 4; the two sides of the front baffle 104 are respectively inserted into the slots 403 on both sides; a connecting sleeve 101 is provided on the cover plate 1; a threaded hole 401 is provided on the bottom housing 4; a bolt passes through the connecting sleeve 101 and is threadedly connected to the threaded hole 401; a guide ring 10401 matching the pin 6 is provided on the inner surface of the front baffle 104; the pin 6 is inserted into the guide ring 10401; the pin 6 is slidably connected to the cover plate 1 through the guide ring 10401;
[0032] After the power assembly is placed into the bottom housing 4, and the bottom housing 4 and the cover plate 1 are pre-assembled into an independent actuator component by bolts, it is convenient to pre-install the entire actuator into the lock. When assembling the lock panel and the bottom plate, the bottom housing 4 and the cover plate 1 are further pressed together to prevent the bottom housing 4 and the cover plate 1 from loosening.
[0033] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
