Description

Technical Field

[0001] This utility model relates to the field of seat lock technology, specifically to an electric seat lock. Background Technology

[0002] Electric vehicles and motorcycles are common modes of transportation in our daily lives, especially prevalent in southeastern my country. To facilitate the placement of items, the middle section of the vehicle body under the seat of an electric vehicle or motorcycle is recessed to form a storage space, with the seat serving as the cover. To prevent theft of items from this storage space, a seat lock is required between the seat and the vehicle body.

[0003] Seat locks typically include a locking mechanism and an unlocking device that works in conjunction with it. The locking mechanism includes a mounting bracket, a hook pivotally connected to the mounting bracket, a locking hook that works in conjunction with the hook to lock or unlock the seat latch, and two tension springs connected to the hook and the locking hook. Existing seat locks lack a status indicator function, thus failing to indicate to the driver whether the seat lock is locked or unlocked, reducing its anti-theft performance. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an electric seat lock that can accurately indicate the opening and closing status of the seat and has high anti-theft performance.

[0005] To address the above problems, the following technical solution is provided: an electric seat lock, including a locking mechanism and an unlocking device that works in conjunction with it. The locking mechanism includes a mounting bracket, a hook pivotally connected to the mounting bracket, 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. It also includes a sensing device. A housing is mounted on the mounting bracket, and a cover is provided at one end of the housing opposite to the mounting bracket. A receiving groove for installing the unlocking device is provided inside the housing, and a mounting groove is provided on the housing above the receiving groove. The sensing device includes a circuit board located inside the housing, a power cord electrically connected to the circuit board, a push switch installed in the mounting groove and electrically connected to the power cord, and a spring corresponding to the push switch. The swing of the locking hook controls the spring to abut or separate from the push switch, thereby transmitting the opening and closing state of the seat lock.

[0006] In the above structure, the power cord is connected to the main unit of the electric vehicle or motorcycle. The seat lock is unlocked through the unlocking device. During unlocking, the end of the lock hook connected to the pull hook with the tension spring swings towards each other. After the lock hook swings, it separates from the spring, and the spring releases the switch head of the push switch, realizing signal transmission. The screen of the electric vehicle or motorcycle displays an icon indicating that the seat lock is unlocked, reminding the user that the seat lock is in the unlocked state. When the user closes the seat, the locking tongue at the bottom of the seat engages with the lock hook. The end of the lock hook connected to the pull hook with the tension spring swings in opposite directions, and the pull hook limits the lock hook. The unlocking device resets and limits the pull hook. The lock hook swings, pressing against the spring, and the spring presses against the switch head of the push switch, realizing signal transmission. The icon indicating that the seat lock is unlocked displayed on the screen of the electric vehicle or motorcycle goes out, informing the user that the seat lock is locked. By setting up a sensing device, it is easy for the user to know, thereby improving the anti-theft performance of this utility model and improving the convenience and comfort of the user. The inclusion groove facilitates the installation of the unlocking device, thereby simplifying the assembly of this invention. The mounting groove also facilitates the installation of the push-button switch, further enhancing the ease of assembly.

[0007] The present invention is further configured such that one end of the spring is fixed to the push switch, and the other end extends out of the housing to correspond to the push head of the push switch.

[0008] The above structure facilitates the pressing of the switch by the spring, thereby improving the reliability of this invention.

[0009] The present invention is further configured such that the housing and the locking mechanism are disposed on the same side.

[0010] By adopting the above structure, the overall size of this utility model can be reduced, thereby facilitating its installation.

[0011] The present invention is further configured such that a sealing groove is provided on the open end face of the housing, and a sealing strip corresponding to the sealing groove is provided on the housing cover.

[0012] In the above structure, the cover and the shell are sealed together by ultrasonic waves. The sealing performance between the cover and the shell is improved by the cooperation of the sealing strip of the cover and the sealing groove of the shell.

[0013] The present invention is further configured such that a wire-holding groove communicating with the mounting groove is provided on the groove wall of the receiving groove, and a wire-passing hole for the power cord to pass through is provided on one side of the housing.

[0014] In the above structure, the installation of the power cord is facilitated by the wire slot and the wire through hole, and the stability of the power cord is improved, thus enhancing the reliability of this utility model.

[0015] The present invention is further provided that a limiting block adapted to the mounting groove is protruding from one side of the shell cover.

[0016] In the above structure, the push switch can be limited by setting a limit block, thereby improving the tightness of the push switch in the mounting groove and thus improving the stability of the push switch.

[0017] The present invention is further provided that the hook has a protruding hanging block, and the hanging block has a hanging groove.

[0018] In the above structure, the hanging block facilitates the installation of the seat lock's pull cord onto the hanging slot, thereby improving the reliability of this utility model.

[0019] The present invention is further configured such that a snap-fit ​​block is provided on the outside of the hanging block on the mounting bracket, and a snap-fit ​​groove is provided on the snap-fit ​​block.

[0020] In the above structure, the snap-fit ​​block facilitates the connection of the pull rope to the snap-fit ​​groove, thereby improving the stability of the pull rope and enhancing the reliability of this invention.

[0021] The present invention is further configured such that the housing has an injection port corresponding to the mounting groove on the side facing the mounting bracket.

[0022] In the above structure, by opening the glue injection port, the sealing performance of the mounting groove can be improved, thereby improving the reliability of this utility model. Attached Figure Description
