Abstract
Description
Technical Field
[0001] The utility model relates to a motor lock with a compact structure. Background Art
[0002] Motor locks, also known as spiritual locks, are locks that use motors to achieve automatic locking and unlocking functions. Although motor locks are a universal lock, the requirements for motor locks in different regions are obviously different. Take Europe as an example. Many European buildings have unique styles, and the spaces such as doors and windows are relatively compact, so the reserved space for installing motor locks is limited. Motor locks with smaller structures can better adapt to these spaces. For example, they can be installed on narrow door frames or small window sashes of some old buildings without taking up too much space, ensuring the overall coordination and beauty of the building's appearance. At the same time, in some small European mechanical equipment, power tools or electronic products, the internal space layout is very compact. When motor locks are needed to provide locking functions, small-structure motor locks are easier to integrate into these devices without affecting the overall structure of the equipment and the layout of other functional modules. Due to the compact structure and small size of the European version of the motor lock, the overall structural stability is insufficient, and the structural design is unreasonable, making it difficult to meet the size requirements. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a compact motor lock with a simple structure and a reasonable layout, which ensures stable operation of the structure while effectively reducing the volume and having a good use effect.
[0004] To achieve the above-mentioned purpose, the utility model provides a motor lock with a compact structure, comprising a base and a cover plate, the base and the cover plate are combined to form a lock body, a lock tongue, a driving motor and a lock core are arranged in the base, the lock tongue is slidably matched with the base, a matching seat is connected to the lock tongue, the matching seat is slidably arranged in the base, a driving member for driving the lock tongue to retract and retract is arranged on the lock core, the driving motor and the driving member are connected by a gear set, the gear set comprises meshing double-layer gears and a transmission gear, the first axial gear in the double-layer gear is connected to the driving motor, the second axial gear of the double-layer gear is meshed with the transmission gear, the transmission gear is connected to the driving member, a matching gap is formed between the first axial gear in the double-layer gear and the driving gear, the matching seat is arranged corresponding to the matching gap position, and the matching gap height is greater than the matching seat thickness setting.
[0005] The beneficial effect of such a setting is that the clearance formed by the matching gap avoids mutual interference between the lock tongue and the gear transmission system during the forward and backward sliding process. The matching seat can move smoothly in this specially reserved matching gap, which greatly improves the smoothness of the lock tongue movement. In traditional motor locks, the interference between the lock tongue and the transmission component may cause operation jamming, and this design effectively solves this problem. In terms of functional stability, this design provides a stable environment for the extension and retraction of the lock tongue. When the drive motor drives the drive member to work through the gear set, the lock tongue can accurately move forward and backward according to the predetermined trajectory to achieve reliable unlocking and locking functions. Due to the reduction of interference, the probability of mechanical wear and failure is reduced, thereby extending the service life of the motor lock. From the perspective of overall performance improvement, the clearance makes the operation of the motor lock more efficient. The lock tongue can respond quickly to the drive signal and slide quickly forward and backward, which improves the speed of unlocking and locking. Moreover, this design makes the structure of the motor lock more compact, saves internal space, and is conducive to the installation and use of the motor lock in various scenarios with limited space, further improving the applicability and competitiveness of the product.
[0006] As a further configuration of the utility model, a guide frame is provided on the cover plate at a position corresponding to the matching seat, a guide groove and a guide block are provided between the guide frame and the matching seat, and the guide block is slidably matched with the guide groove.
[0007] The beneficial effect of such a setting is that the sliding cooperation between the guide block and the guide groove provides precise guidance for the movement of the matching seat. When the lock tongue slides back and forth under the action of the drive motor and other components, the matching seat can move smoothly along the predetermined track of the guide groove, avoiding the deviation caused by lateral force or other factors. This precise guidance greatly reduces the jamming phenomenon during the sliding process of the lock tongue, making the extension and retraction action of the lock tongue smoother. At the same time, the stable sliding can also reduce the wear between components, extend the service life of the motor lock, and ensure the long-term and reliable operation of the motor lock.
[0008] As a further configuration of the utility model, a support plate is further extended from the driving member toward the matching seat, and the support plate is arranged below the matching seat.
[0009] The beneficial effect of this arrangement is that the support plate extending from the driving member toward the mating seat improves the position stability of the mating seat and effectively ensures smooth sliding. The support plate is arranged below the mating seat to form a support platform. During the sliding movement of the lock tongue back and forth, the mating seat will be subject to certain vibrations and external forces. The support plate can effectively bear these forces to prevent the mating seat from shaking, offsetting, etc., and ensure that it is always in the correct position. This avoids the jamming and stuck phenomenon caused by the unstable position of the mating seat, and allows the sliding of the lock tongue to be smoother. Moreover, the stable mating seat can also ensure the stable operation of the entire transmission system, further improving the reliability and efficiency of the unlocking and locking functions of the motor lock.
[0010] As a further configuration of the utility model, a wiring port is provided on the side wall of the base, a circuit board is provided on the base, the circuit board includes a longitudinal portion and a transverse portion connected to each other, the longitudinal portion and the transverse portion are connected and combined into an L shape, the transverse portion is arranged close to the wiring port, and the longitudinal portion is arranged between the drive motor and the side wall of the base.
[0011] The beneficial effect of this arrangement is that the side wall of the base is provided with a wiring port, and the circuit board is composed of a longitudinal part and a transverse part connected in an L shape. The transverse part is arranged close to the wiring port. This design makes wiring work extremely convenient, and the staff can easily connect the external line to the circuit board, which improves the efficiency of installation and maintenance. The longitudinal part is arranged between the drive motor and the side wall of the base, making full use of the space inside the motor lock that is originally easy to be wasted, and avoiding unreasonable occupation of space. This layout arranges the various components tightly and orderly, making the entire motor lock structure more compact, not only reducing the product volume, but also enhancing the overall stability and reliability.
[0012] As a further configuration of the utility model, the upper and lower end surfaces of the driving member are respectively provided with guide grooves, and the base and the cover plate are provided with guide blocks at positions corresponding to the guide grooves, and the guide blocks are slidably matched with the guide grooves.
[0013] The beneficial effect of such a setting is that the guide grooves on the upper and lower end surfaces of the driver slide in cooperation with the guide blocks correspondingly arranged on the base and the cover plate, which plays a key role in ensuring the stability of the guide block sliding. When the drive motor drives the driver to work through the gear set, the guide block slides in the guide groove, providing precise guidance for the movement of the driver. This matching method can effectively limit the movement trajectory of the driver, so that it can only move smoothly along the direction of the guide groove, avoiding the driver from shaking, deflecting and other unstable situations during the movement. Stable sliding can also reduce the collision and friction between the driver and other components, reduce wear, and extend the service life of the components, thereby ensuring the overall stable operation and reliable performance of the motor lock.

The base 1 is provided with a lock tongue 6, a driving motor 4 and a lock core. The lock tongue 6 is slidably matched with the base 1, and a matching seat 61 is connected to the lock tongue 6. The matching seat 61 is slidably set in the base 1. A driving member 3 for driving the lock tongue 6 to retract is provided on the lock core. The driving motor 4 and the driving member 3 are connected by a gear set. The gear set includes a meshing double-layer gear 41 and a transmission gear 42. The first axial gear in the double-layer gear 41 is connected to the driving motor 4, and the second axial gear of the double-layer gear 41 is meshed with the transmission gear 42. The transmission gear 42 is connected to the driving member 3. A matching gap is formed between the first axial gear in the double-layer gear 41 and the driving gear. The matching seat 61 is arranged corresponding to the matching gap position, and the matching gap height is greater than the thickness of the matching seat 61. The beneficial effect of such a setting is that the clearance formed by the matching gap avoids mutual interference between the lock tongue 6 and the gear transmission system during the forward and backward sliding process. The matching seat 61 can move smoothly in this specially reserved matching gap, which greatly improves the smoothness of the movement of the lock tongue 6. In traditional motor locks, the interference between the lock tongue 6 and the transmission components may cause operation jams, and this design effectively solves this problem. In terms of functional stability, this design provides a stable environment for the extension and contraction of the lock tongue 6. When the drive motor 4 drives the drive member 3 to work through the gear set, the lock tongue 6 can accurately move forward and backward according to the predetermined trajectory to achieve reliable unlocking and locking functions. Due to the reduction of interference, the probability of mechanical wear and failure is reduced, thereby extending the service life of the motor lock. From the perspective of overall performance improvement, the clearance makes the operation of the motor lock more efficient. The lock tongue 6 can respond quickly to the drive signal, slide quickly forward and backward, and improve the speed of unlocking and locking. Moreover, this design makes the structure of the motor lock more compact, saves internal space, and is conducive to the installation and use of the motor lock in various scenarios with limited space, further improving the applicability and competitiveness of the product.
[0018] As a further configuration of the present embodiment, a guide frame 21 is provided on the cover plate 2 at a position corresponding to the matching seat 61, and a guide groove and a guide block 62 are provided between the guide frame 21 and the matching seat 61, and the guide block 62 is slidably matched with the guide groove. The beneficial effect of such a configuration is that the sliding match between the guide block 62 and the guide groove provides precise guidance for the movement of the matching seat 61. When the lock tongue 6 slides back and forth under the action of the drive motor 4 and other components, the matching seat 61 can move smoothly along the predetermined trajectory of the guide groove, avoiding deviation caused by lateral force or other factors. This precise guidance greatly reduces the jamming phenomenon during the sliding process of the lock tongue 6, making the telescopic action of the lock tongue 6 smoother. At the same time, the stable sliding can also reduce the wear between components, extend the service life of the motor lock, and ensure the long-term and reliable operation of the motor lock.
[0019] As a further configuration of this embodiment, a support plate 31 is also extended from the driving member 3 toward the matching seat 61, and the support plate 31 is arranged below the matching seat 61. The beneficial effect of such configuration is that the support plate 31 extending from the driving member 3 toward the matching seat 61 improves the position stability of the matching seat 61 and effectively ensures smooth sliding. The support plate 31 is arranged below the matching seat 61 to form a supporting platform. During the sliding movement of the lock tongue 6 back and forth, the matching seat 61 will be subjected to certain vibrations and external forces. The support plate 31 can effectively bear these forces to prevent the matching seat 61 from shaking, deflecting, etc., and ensure that it is always in the correct position. This avoids the jamming and stuck phenomenon caused by the unstable position of the matching seat 61, and makes the sliding of the lock tongue 6 smoother. Moreover, the stable matching seat 61 can also ensure the stable operation of the entire transmission system, further improving the reliability and efficiency of the unlocking and locking functions of the motor lock.
[0020] As a further configuration of this embodiment, a wiring port 11 is provided on the side wall of the base 1, and a circuit board 5 is provided on the base 1. The circuit board 5 includes a longitudinal portion 51 and a transverse portion 52 connected to each other, and the longitudinal portion 51 and the transverse portion 52 are connected and combined into an L shape, and the transverse portion 52 is arranged near the wiring port 11, and the longitudinal portion 51 is arranged between the drive motor 4 and the side wall of the base 1. The beneficial effect of this configuration is that the wiring port 11 is provided on the side wall of the base 1, and the circuit board 5 is composed of the longitudinal portion 51 and the transverse portion 52 connected into an L shape. The transverse portion 52 is arranged near the wiring port 11, and this design makes the wiring work extremely convenient, and the staff can easily connect the external circuit to the circuit board 5, thereby improving the installation and maintenance efficiency. The longitudinal portion 51 is arranged between the drive motor 4 and the side wall of the base 1, making full use of the space inside the motor lock that is originally easy to be wasted, and avoiding unreasonable occupation of space. This layout allows the various components to be arranged closely and orderly, making the entire motor lock structure more compact, not only reducing the product volume, but also enhancing the overall stability and reliability.

The beneficial effect of such configuration is that the guide grooves 32 on the upper and lower end surfaces of the driving member 3 slide and cooperate with the guide blocks 22 correspondingly provided on the base 1 and the cover plate 2, which plays a key role in ensuring the stability of the sliding of the guide blocks 22. When the driving motor 4 drives the driving member 3 to work through the gear set, the guide block 22 slides in the guide groove 32, providing precise guidance for the movement of the driving member 3. This matching mode can effectively limit the movement trajectory of the driving member 3, so that it can only move smoothly along the direction of the guide groove 32, avoiding the unstable conditions such as shaking and offset of the driving member 3 during the movement. Stable sliding can also reduce the collision and friction between the driving member 3 and other components, reduce wear, and extend the service life of the components, thereby ensuring the overall stable operation and reliable performance of the motor lock.
