Technical Field
[0001] This utility model relates to the technical field of motorcycle tail box lock structure, specifically a motorcycle tail box lock structure. Background Technology
[0002] A motorcycle tailgate lock is a safety device installed on the storage box at the rear of a motorcycle. It is primarily used to secure and protect items inside the box. Its core structure includes a lock body, lock cylinder, key, and fixing device, and its opening and closing are controlled mechanically or electronically. The core components of the tailgate lock consist of a lock cylinder shell, a lock chip, a spring, and a lock cylinder pin. The lock cylinder works by utilizing the interaction between the pin and the lock chip; rotating the lock cylinder opens and closes the lock. When the pin and lock chip are fully engaged, the lock is closed; when they are disengaged, the lock is open. The precision of the lock cylinder design and the choice of materials have a significant impact on the security and durability of the trunk lock. The lock body, the outer shell of the trunk lock, consists of the lock body shell, bolt, and bolt. The lock operates by extending and retracting the bolt to open and close the lock; when the bolt extends, the lock is closed; when the bolt retracts, the lock is open. The design and materials of the lock body significantly affect the trunk lock's anti-theft performance and lifespan. The lock connection part is the connecting device between the lock cylinder and the lock body, consisting of connecting screws and connecting pins. The principle of the lock connection part is to use connecting screws and connecting pins to tightly fix the lock cylinder and lock body together, ensuring the normal use and security of the lock. The existing motorcycle tail box lock mechanism requires separate installation on the lock body, typically using a hinged installation. This hinged installation involves inserting a pin into the hinge seat, and a separate latching spring is required outside the pin for latching. A separate torsion spring structure is installed on its surface to generate torsional pressure on the lock mechanism for latching and resetting. However, the installation of the torsion spring is inconvenient, and the elasticity of the torsion spring structure is easily reduced with repeated use. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a motorcycle tail box lock structure to solve the problem of inconvenient hinged installation of the lock plate mechanism and the problem of inconvenient installation of the torsion spring and easy reduction of its reset elasticity.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle tail box lock structure, comprising a motorcycle tail box lock body, a motorcycle tail box lock opening at the outer end of the motorcycle tail box lock body, a hinge support seat on the upper surface of the outer end of the motorcycle tail box lock body, a hinge positioning groove on one side of the hinge support seat, a hinge support shaft body on the inner surface of the hinge positioning groove, a locking plate mechanism fixedly connected to the outer surface of the middle end of the hinge support shaft body, a lock groove on the upper surface of the locking plate mechanism, a support protrusion fixedly connected to the outer surface of the hinge support seat, an arched spring plate fixedly connected to the outer end of the support protrusion, positioning paddles fixedly connected to both sides of the hinge support shaft body, the outer end of the arched spring plate pressing against the outer surface of the positioning paddle, and a sliding positioning support block on the inner surface of the hinge support seat, the sliding positioning support block supporting the outer surface of the hinge support shaft body.
[0005] Preferably, the surface of the hinge support is provided with a convex groove, and a sliding positioning support block and a spring are slidably connected in the convex groove.
[0006] Preferably, the inner end of the sliding positioning support block is provided with a circular notch, which is supported on the outer surface of the hinged support shaft body, and the outer end surface of the sliding positioning support block is provided with a rounded corner.
[0007] Preferably, the arched spring sheet is made of stainless steel elastic sheet material.
[0008] Preferably, the upper and lower end surfaces of the hinge support shaft body are supported on the inner surface of the hinge positioning groove of the hinge support seat.
[0009] Preferably, the inner end of the positioning paddle is attached to the outer surface of the hinged support.
[0010] Preferably, the outer surface of the motorcycle tail box lock body is provided with mounting holes, which are distributed on the left and right sides of the motorcycle tail box lock body.
