Description
Technical Field
[0001] The utility model relates to the technical field of shared equipment, in particular to a direct-pull motor lock. Background Art
[0002] There are two main types of anti-theft locks for shared power banks: electromagnetic locks and transmission anti-theft locks.
[0003] Transmission anti-theft locks utilize a worm drive and motor control to achieve anti-theft functionality. These locks typically include a carrier plate, a lock box, a cavity, and a current detection circuit. The motor unlocks the lock shaft, while the current detection circuit ensures that the lock is unlocked only when the power bank is properly returned, enhancing security.
[0004] However, the lock rod and lock tongue in the existing shared power bank anti-theft lock are an integrated structure. When the lock rod is inserted into the gap of the power bank placement cavity of the charging cabinet to press the lock tongue, the lock tongue and the lock rod will be pushed. As a result, when encountering a large external force, the shared power bank is likely to slide out of the placement cavity, losing the locking function, which is not conducive to anti-theft and cannot ensure that the power bank cannot be easily taken out without authorization. Utility Model Content
[0005] The utility model provides a direct-pull motor lock, which solves the technical problems of unreasonable anti-theft lock structure and poor anti-theft effect of existing shared power banks.
[0006] In order to solve the above technical problems, the utility model provides a direct-pull motor lock, comprising an upper cover, a lower cover, and a motor toggle assembly, a lock arm, a lock tongue, and a spring kit installed in the lower cover; the lock tongue is installed in a transverse sliding manner in the lower cover, and its middle portion is locked and nested with the lock arm; the motor toggle assembly is installed in the middle portion of the lower cover, and is provided with a movable end extending outward; the middle portion of the lock arm is rotatably installed with the lower cover, one end extends forward to face the motor toggle assembly, the other end extends backward to nest on the lock tongue, and the inner side of the other end is also fixedly connected to the spring kit;
[0007] The movable end rotates clockwise / counterclockwise under power, pushing one end of the locking arm to deflect, while the other end of the locking arm deflects and drives the lock tongue to extend or retract, thereby locking or unlocking.
[0008] This basic solution is based on the current anti-theft needs of power banks. It specifically sets up a combined lock arm and lock tongue. The lock tongue is installed horizontally and slidably in the lower cover so that it is in a spatial vertical relationship with the side wall of the charging compartment. External force cannot be applied to the lock tongue to make it move left or right, so that the power bank can always be locked without authorization. It has good anti-theft effect, simple structure, very convenient access, and is safe and reliable.
[0009] In a further embodiment, the lock tongue is a cylindrical structure with a downwardly recessed slot in the middle.

The connection between the curved structure and the outer side wall of the lock tongue is a smooth arc structure; the distance between the midpoints of the side walls on both sides of the slot is smaller than the distance between the edges of the side walls on both sides.
[0010] This solution sets a cylindrical structure as a lock tongue, which can ensure the locking security with the power bank on the one hand, facilitate the sliding operation of locking and unlocking on the other hand, and also remove external force interference to ensure the safety of equipment and property.
[0011] In a further embodiment, a sliding groove extending transversely therethrough is provided on the rear side of the lower cover, and symmetrical first placement grooves are provided downwardly on both side walls of the sliding groove; the sliding groove is a smooth curved groove; the width of the first placement groove is greater than the width of the locking slot, and the width of the first placement groove is less than the length of the locking tongue;
[0012] The locking tongue is placed in the sliding groove, the locking arm is embedded in the first placement groove and is arranged above the sliding groove, and the locking groove is nested with the locking arm facing upward.
[0013] This solution provides a smooth curved groove for the lock tongue to move, and sets a first placement groove to match the radially installed lock arm. Through the continuous action of the motor-lock arm-lock tongue, flexible control of unlocking and locking is achieved. The structure is simple and the device has high sensitivity.
[0014] In a further embodiment, a first rotating shaft is provided in the middle of the locking arm, and the upper and lower ends of the first rotating shaft respectively pass through the upper cover and the lower cover, and the locking arm rotates and swings with the first rotating shaft as the center point; one end of the locking arm is bent forward and extended to form a horizontal swing piece facing the motor toggle assembly, and the other end extends backward to form a limit buckle nested with the lock tongue; the limit buckle is a radially placed strip swing piece; a raised spring mounting position is also provided on the inner side of the other end of the locking arm, and the spring mounting position is provided with the spring kit.

[0016] A second rotating shaft is provided in the middle of the linkage paddle, and the upper and lower ends of the second rotating shaft pass through the upper cover and the lower cover respectively; the two sides of the second rotating shaft form a first toggle block corresponding to the locking arm, and the middle part of the rear end protrudes backward to form a second toggle block corresponding to the motor paddle cover.
[0017] This solution sets a linkage paddle as a power transfer structure for the motor and the lock arm. The motor drives the motor paddle sleeve to push the linkage paddle, and the linkage paddle further drives the lock arm to rotate, so as to push out or bring back the lock tongue to achieve locking and unlocking of the power bank. The product is simple and the device is highly integrated.
[0018] In a further embodiment, the motor paddle sleeve is a cylindrical structure, the inner cavity of its bottom plate is provided with a fixed groove which is sleeved with the motor shaft, and the outer wall is provided with a third toggle block protruding outward, and the third toggle block is the movable end of the motor toggle assembly extended outward; when the motor is started, it drives the motor paddle sleeve to rotate so that the third toggle block is connected to the second toggle block, and the third toggle block drives the linkage paddle to rotate as a whole under the push of the third toggle block.
[0019] In a further embodiment, both ends of the upper cover are provided with vertical downward-pointing clips, and the outer side walls at both ends of the lower cover are provided with mounting buckles that engage with the clips.
