Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to a feedback type seat cushion lock. Background Art

[0002] Electric vehicles and motorcycles are common modes of transportation in our daily lives, particularly in southeastern my country. To facilitate the placement of items, the center of the vehicle body beneath the seat of an electric vehicle or motorcycle is recessed to create a storage space. The seat serves as a cover for this storage space. To prevent theft, a seat lock is required between the seat and the vehicle body.

[0003] A seat lock typically consists of a locking mechanism and an unlocking device that works in conjunction with it. The locking mechanism includes a mounting frame, a hook pivotally connected to the mounting frame, a locking hook that works in conjunction with the hook to lock or unlock the seat lock tongue, and a tension spring connected to the hook and the locking hook. Existing seat locks lack a status indicator, making it impossible to tell the driver whether the seat lock is locked or unlocked, reducing their anti-theft performance. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a feedback seat cushion lock with a status prompt function, which is convenient for the driver to use and can lock the seat cushion in time to improve safety.

[0005] In view of the above problems, the following technical solutions are provided: a feedback type seat cushion lock, comprising a locking mechanism, a shell and a shell cover matched with the shell cover, the locking mechanism comprising a mounting frame, a pull hook pivotally connected to the mounting frame, a lock hook that cooperates with the pull hook to lock or unlock the seat cushion lock tongue, and a tension spring connected to the pull hook and the lock hook, the shell is mounted on the mounting frame, a lock mouth is provided on the lock hook, a locking portion is protruding from the end of the lock hook relative to the lock mouth, a locking groove matched with the locking portion is provided on the pull hook, and a guide mouth is provided on the pull hook above the locking groove; it also includes a sensing device and an unlocking device, and the shell is installed inside. A accommodating groove is provided, and the sensing device includes a circuit board located in the accommodating groove and a micro switch electrically connected to the circuit board. The switch head of the micro switch protrudes from the shell and is located on the stroke in the unlocking swing direction of the lock hook. The lock hook is provided with an abutment block for abutting the micro switch after unlocking. The unlocking device includes a driving motor located in the accommodating groove and electrically connected to the circuit board, a transmission component that transmits and cooperates with the driving motor, and a push plate that transmits and cooperates with the transmission component. A sliding groove that cooperates with the push plate is provided on the side of the shell facing the mounting frame. The lock hook controls the transmission component through the driving motor to drive the push plate to push the pull hook to achieve unlocking.

[0006] In the above structure, when the seat lock is unlocked by a key or a control button, the driving motor controls the push plate to move toward the outer end of the slide slot through the transmission assembly, and the push plate pushes the pull hook to swing relative to the pivot point of the mounting frame, and then drives the lock hook to work in conjunction through the tension spring, so that the locking part disengages from the locking slot, thereby unlocking the seat lock. After unlocking, the abutment block on the lock hook presses against the micro switch, and the driving motor controls the push plate to reset through the transmission assembly. When the push plate is reset, the pull hook is reset at the same time; when the seat lock is not locked after the set time, the buzzer on the electric vehicle or motorcycle sounds, which serves as a warning to the driver, thereby improving the safety and anti-theft function of the utility model and making it convenient for the driver to use. When the seat lock is closed, the locking tongue at the bottom of the seat is engaged with the locking notch of the lock hook. When the locking tongue on the seat is pressed down, the lock hook is driven to reset and swing, the abutment block is disengaged from the micro switch, and the locking portion is guided into the locking groove through the guide opening. The locking groove on the pull hook then limits the lock hook, thus locking the seat lock. The provision of the sliding groove can improve the stability of the push plate during displacement, thereby improving the reliability of the utility model.
