Abstract
Description
Technical Field
[0001] This utility model relates to the field of seat belt lock technology, specifically to a mounting structure for an automotive seat belt lock mounting plate. Background Technology
[0002] The seatbelt latch mounting plate is a key structural component connecting the seatbelt latch to the vehicle body. It is typically made of high-strength steel or alloy, possessing excellent impact and deformation resistance to ensure stable support of the seatbelt latch in emergencies. The mounting plate is precisely designed with specific holes for a secure fit against the vehicle frame, making installation simple and robust. Its surface is treated with rust prevention to resist harsh environments and extend its service life.
[0003] Utility model patent CN206654026U discloses a rigid car seat buckle assembly, comprising two symmetrically arranged seat buckle units. Each seat buckle unit includes a seat buckle, a buckle mounting plate, a buckle connecting plate, a return torsion spring, and an "L"-shaped seat belt mounting bracket. When the backrest flips forward around the seat axis, it presses down on the seat buckle. The seat buckle and buckle mounting plate rotate together around the first hinge point, compressing the return torsion spring. When the backrest is flipped forward to its final position, the first limiting protrusion contacts the third limiting protrusion. When the backrest flips backward around the seat axis, the seat buckle and buckle mounting plate automatically return to their original position under the restoring force of the return torsion spring. When the backrest returns to its initial position, the first limiting protrusion contacts the second limiting protrusion. The seat buckle and buckle connecting plate are connected by a buckle mounting plate made of rigid material, fixing the position of the seat buckle and not affecting the normal flipping of the seat. Two seat buckles can be installed simultaneously.
[0004] However, common car seat belt latches are installed in the corner of the car seat, and the latch mounting plate is usually located inside the seat cover. The latch has a limited lifespan due to constant plugging and unplugging. Replacing the latch requires removing the seat cover, making the replacement difficult. Therefore, a new car seat belt latch mounting plate installation structure is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a convenient and quick replacement structure for car seat belt lock mounting plates, solving the problem that existing car seat belt locks require the removal of the seat cover during replacement, making lock replacement difficult.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An automotive seatbelt lock mounting plate mounting structure includes a lock and a connecting plate disposed at the bottom of the lock. The automotive seatbelt lock mounting plate mounting structure also includes an extension plate fixedly installed at the bottom of the connecting plate, three replacement holes formed on one side of the connecting plate, and a connecting assembly for connecting the lock and the connecting plate.
[0008] The connecting assembly includes a replacement screw and a countersunk hole. The bottom of the latch has a connecting groove, and the connecting plate is slidably installed inside the connecting groove. The replacement screw passes through the replacement hole and is threadedly connected to the threaded hole on the latch. A countersunk hole is provided on one side of the latch, and the head of the replacement screw is located inside the countersunk hole.
[0009] Furthermore, the top of the lock is provided with a insertion slot, and a locking structure is provided inside the insertion slot.
[0010] Furthermore, a connection sensor is fixedly installed at the bottom of the insertion slot, and a wire is fixedly installed on one side of the lock.
[0011] Furthermore, a signal plug is fixedly installed at one end of the wire, and the wire is electrically connected to the connection sensor.
[0012] Furthermore, a rotating plate is fixedly installed at the bottom of the extension plate, and a rotating hole is provided on one side of the rotating plate.
[0013] Furthermore, a mounting plate is rotatably mounted on one side of the rotating plate, and three mounting holes are provided on one side of the mounting plate.
[0014] Furthermore, a rotating shaft is provided on one side of the mounting plate, and the rotating plate is rotatably mounted on the surface of the rotating shaft.
[0015] Furthermore, the rotating shaft is adapted to the rotating hole, and a mounting screw is provided on one side of the mounting plate, the mounting screw being adapted to the three mounting holes.
[0016] Compared with the prior art, this utility model provides a mounting structure for an automotive seatbelt lock mounting plate, which has the following advantages:
[0017] This automotive seatbelt lock mounting plate structure features a connecting groove at the bottom of the lock. The lock is simply fitted onto the top of the connecting plate through this groove, and a replacement screw is passed through the replacement hole on the connecting plate and threaded into the lock's threaded hole to install it onto the connecting plate. When the lock needs replacement, simply loosen the replacement screw to remove the damaged lock from the connecting plate, replace it with a new lock, and then tighten the replacement screw. This solves the problem of existing automotive seatbelt lock replacement technologies requiring the removal of the seat cover, which made replacement difficult. Attached Figure Description
