Implementation

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is used to help understand the present invention, it does not constitute a limitation of the present invention.

[0021] The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms and should not be construed as limited to the embodiments set forth herein.

[0022] According to a specific embodiment of the present disclosure, an electric-controlled smart lock is provided. Figures 1 to 9 One specific implementation method is shown.

[0023] See also Figures 1 to 9 As shown, the electric-controlled smart lock includes a shell 1 and a lock control plate 2 arranged in the shell 1, and is characterized in that the electric-controlled smart lock includes a driver 3, a gear assembly, a pusher 5 and a locking member 6; the driver 3 is electrically connected to the lock control plate 2, and the drive shaft of the driver 3 is driven; the locking member 6 is arranged above the pusher 5; the locking member 6 has a lock groove 61 for matching with the lock buckle 7; the lock buckle 7 is U-shaped, including an open end and a solid end relative to the open end, and the open end is away from the locking member 6, so that the solid end of the lock buckle 7 can be inserted into the lock groove 61.

[0024] The pushing member 5 is rotatably connected to the shell 1 through a positioning shaft. The pushing member 5 includes a push rod 51 for pushing the locking member 6 and a limiting rod 53 arranged below the push rod 51. The limiting rod 53 is spaced apart from the push rod 51, and there is an angle between the two. A first torsion spring 81 is provided on the positioning shaft, and an extended section of the first torsion spring 81 presses against the upper end surface of the push rod 51.

[0025] The gear assembly includes a second driven wheel 46, on which a C-shaped cam guide platform 120 adapted to the limiting rod 53 is provided. The cam guide platform 120 is coaxially arranged with the second driven wheel 46, and an unclosed area of ​​the cam guide platform 120 is formed as a locking groove.

[0026] The electric-controlled smart lock has a locked state and an unlocked state; in the locked state, the limit rod 53 is pressed against the cam guide platform 120 to rotate, the push rod 51 moves downward, the locking piece 6 flips downward and locks the lock buckle 7; in the unlocked state, the limit rod 53 is set in the locking groove, the push rod 51 moves upward, the locking piece 6 flips upward and releases the lock buckle 7.

[0027] Through the above technical solution, the release and locking of the lock 7 by the locking member 6 can be achieved by controlling the motion state of the driver 3. Because the locking member 6 has an inclined angle relative to the lock 7 when the locking member 6 turns over, the lock groove 61 thereof can play a certain locking role on the lock 7 based on the physical structure of the locking member 6. At the same time, based on the torque generated by the first torsion spring 81, the pusher 5 can be continuously and effectively abutted against the locking member 6, thereby ensuring the stability and reliability of the locking effect of the lock 7. When the driver 3 rotates in the opposite direction, the first torsion spring 81 can be reset, and the pressure on the locking member 6 can be indirectly released by the pusher 5, thereby helping the locking member 6 to reset, so that the lock groove 61 is parallel to the lock 7, so that the lock 7 can move horizontally in the lock groove 61, and then complete the unlocking action. The electric control intelligent lock has a simple structure and reliable power transmission, so that the entire unlocking and locking process can be carried out stably, and the reliability of the lock 6 and the lock 7 when they cooperate is effectively guaranteed. The electric-controlled intelligent lock has a compact structure, small size, easy use and assembly, good safety and stability, and low manufacturing cost. It is suitable for use as a door lock for safes, storage boxes, and lockers.

[0028] It should be noted that the role of the gear assembly is to play a role in power transmission, so as to transmit the power output by the driver 3 to the first torsion spring 81, thereby driving the pusher 5 to flip. Furthermore, the power mechanism can also play a role in deceleration and torque increase, thereby slowing down the rotation speed of the first torsion spring 81, so that the pusher 5 can smoothly push the locking member 6 and reduce rigid impact.

[0029] In an embodiment provided by the present disclosure, an L-shaped escape hole is provided at the end of the push rod 51; the end of one end of the locking member 6 is formed into a shape that matches the escape hole, so that the end of the lock member 6 can fit in the escape hole. This design can increase the contact area between the push member 5 and the locking member 6, and better transmit power through the concave-convex matching relationship between the two, and can prevent slipping.

[0030] In one embodiment provided by the present disclosure, the limiting rod 53 has an angle with respect to the push rod 51, and the angle between the two is 110° to 130°. In this way, the rotation amplitude of the push rod 51 and the limiting rod 53 can be controlled within a certain range, thereby reducing the waiting time for unlocking and locking.

[0031] In an embodiment provided by the present disclosure, the thickness of the cam guide platform 120 is arranged on the second driven wheel 46 in a gradual structure of first thickening and then thinning along its circumferential direction, and the cam guide platform 120 is symmetrically arranged relative to the second driven wheel 46. Such a design is beneficial for the cam guide platform 120 to push the limit rod 53 to move smoothly, thereby reducing vibration.

[0032] See also Figures 1 to 9 As shown, the pusher 5 also includes a pressure rod 52, which is arranged between the push rod 51 and the limit rod 53. The electric-controlled intelligent lock also includes a second micro switch 112 and a third micro switch 113 which are electrically connected to the lock control plate 2. The second micro switch 112 and the pressure rod 52 are arranged relative to each other and connected to the housing 1. When the push rod 51 moves to the upper limit position, the pressure rod 52 abuts against the reed of the second micro switch 112; the third micro switch 113 and the limit rod 53 are arranged relative to each other and connected to the positioning frame 91. When the limit rod 53 moves to the lower limit position, the limit rod 53 abuts against the reed of the third micro switch 113. In this way, the lock control plate 2 controls the driver 3 to perform corresponding actions according to the information transmitted by the second micro switch 112 and the third micro switch 113.

[0033] In an embodiment provided in the present disclosure, a limiting hole 101 is provided on the shell 1, and a pressing surface adapted to the upper end of the limiting hole 101 is provided on the outer periphery of the locking member 6. Such a design can limit the moving range of the locking member 6 to prevent it from excessive movement and affecting its performance; part of the structure of the push rod 51 extends into the limiting hole 101, and the bottom surface of the push rod 51 is formed as an inclined surface. Such a design can also activate a certain limiting effect on the moving range of the push rod 51, avoiding the inclined surface setting based on the inclined surface. When the push member 5 rotates to the effective flipping limit position, the inclined surface can fit the inner wall surface of the limiting hole 101, thereby ensuring the reliability of the limiting effect.

[0034] In one embodiment provided by the present disclosure, the locking member 6 is connected to the housing 1 through a mounting bracket; the electric-controlled smart lock includes a second torsion spring 82, which is fixedly connected to the locking member 6, and the extension section of the second torsion spring 82 is pressed against the mounting bracket. This design can slow down the turning speed of the locking member 6 when it is pushed by the pushing member 5, and at the same time, based on the restoring force of the second torsion spring 82, it is also helpful to help it reset. As a result, the locking member 6 can maintain good movement sensitivity and response accuracy under the elastic force of the second torsion spring 82, whether in the unlocked state or the locked state, to avoid invalid unlocking or invalid locking of the electric-controlled smart lock.

[0035] In an embodiment provided in the present disclosure, the locking member 6 is rotatably connected to the mounting frame via a mounting shaft, and a pressure plate is provided on the mounting shaft; the electrically controlled smart lock also includes a first micro switch 111 electrically connected to the lock control plate 2, the first micro switch 111 is connected to the mounting frame, and the spring plate of the first micro switch 111 faces the pressure plate, so that the movement state of the locking member 6 can be accurately obtained by the touch pressure of the locking member 6.

[0036] In a preferred embodiment provided by the present disclosure, a first micro switch 111 , a second micro switch 112 and a third micro switch 113 are provided at the same time.

[0037] 1. In the cabinet door locked state, the first micro switch 111 and the third micro switch 113 are not pressed, and the second micro switch 112 is pressed; 2. When the cabinet door begins to open, the first micro switch 111 and the second micro switch 112 are not pressed, and the third micro switch 113 is pressed; 3. When the cabinet door is open, the first micro switch 111 is pressed, and the third micro switch 113 is not pressed; 4. When the cabinet door is fully opened and unlocked, the first micro switch 111 and the second micro switch 112 are pressed, and the third micro switch 113 is not pressed; 5. During the locking process, the first micro switch 111 and the second micro switch 112 are not pressed.

[0038] In the present disclosure, the locking member 6 is U-shaped, wherein the middle groove is configured as a locking groove 61, and one end of the locking member 6 is provided with a gap-filling structure matching the pushing member 5 so that the two can fit better, thereby ensuring the reliability of movement.

[0039] In an embodiment provided by the present disclosure, the gear assembly includes a worm 41, a worm wheel 42, a first driving wheel 43, a first driven wheel 44, a second driving wheel 45 and a second driven wheel 46; the worm wheel 42 is coaxially connected to the output shaft of the driver 3; the worm wheel 42 and the first driving wheel 43 are coaxially arranged on the first transmission shaft 47; the first driven wheel 44 and the second driving wheel 45 are coaxially arranged on the second transmission shaft 48, and the second driven wheel 46 is coaxially arranged on the third transmission shaft 49.

[0040] The first transmission shaft 47, the second transmission shaft 48 and the third transmission shaft 49 are connected to the housing 1 in parallel and at intervals in sequence; wherein the worm 41 is meshed with the worm wheel 42, the first driving wheel 43 is meshed with the first driven wheel 44; the second driving wheel 45 is meshed with the second driven wheel 46, and the guide boss 120 on the second driven wheel 46 is arranged opposite to the limit rod 53.

[0041] In this way, when the driver 3 rotates, the worm 41 coaxially fixedly connected thereto can rotate accordingly, and the power is transmitted to the first driving wheel 43 through the cooperation of the worm 41 and the worm wheel 42. Thereafter, the power can be transmitted to the second driving wheel 45 through the cooperation of the first driving wheel 43 and the first driven wheel 44. In this case, the second driven wheel 46 meshing with the second driving wheel 45 can rotate slowly and uniformly, thereby causing the guide boss 120 to rotate and periodically press the limit rod, and the push rod can move upward or downward, thereby adjusting the position of the locking member 6, and releasing and locking the lock catch.

[0042] The cooperation between the worm 41 and the worm wheel 42 is beneficial to improving the effectiveness of power transmission and reducing kinetic energy loss, thereby smoothly transmitting the power output by the driver 3 to the worm wheel 42, thereby driving other gears to rotate.

[0043] It should be noted that the transmission ratio of the first driven wheel 44 to the first driving wheel 43 is greater than 1, and the transmission ratio of the second driven wheel 46 to the second driving wheel 45 is greater than 2. This arrangement can play a role in reducing speed and increasing torque, thereby allowing other gears to rotate smoothly and at a uniform speed under the action of the transmission force.

This design can not only increase the fulcrum points and improve the stability of the positioning effect of the driver 3; the output end of the driver 3 is vertically arranged, so that the power can be effectively transmitted according to the preset trajectory and reduce losses; the lock control plate 2 and the driver 3 are arranged relative to each other, which can optimize the circuit and enable the controller to quickly respond to the instructions issued by the lock control plate 2.

[0045] It should be noted that in the present disclosure, the driver 3 is configured as a motor; the lock control board 2 is a prior art, and those skilled in the art can configure it as a control circuit board in the prior art according to the technical concept of the present disclosure. In this regard, those skilled in the art can flexibly configure it according to the applicable objects, application scenarios and specifications of the electric control smart lock, and the present disclosure does not limit this.

[0046] Specifically, the electric control smart lock includes a positioning frame 91, which is fixedly connected to the housing 1, and the positioning shaft is rotatably connected to the positioning frame 91. The positioning frame 91 is U-shaped, and the positioning frame 91 is covered on the outer periphery of the locking member 6. Both ends of the locking member 6 are rotatably connected to the positioning frame 91 through the shaft, and the second torsion spring 82 is arranged on the shaft of the locking member 6. Therefore, when the second torsion spring 82 is subjected to torsion, it can drive the locking member 6 to rotate.

[0047] It should be noted that the present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention.
