Detailed Description
A locking mechanism for a vehicle seat lock according to the present invention will be described in detail with reference to fig. 1 to 4. The following specific embodiments are one of the technical solutions of the present invention, namely, the priority solution, and are not limiting to the embodiments of the present invention. All obvious changes or modifications which come within the spirit of the invention are desired to be protected.
Example 1
The utility model provides a car seat lock locking mechanism, includes bottom plate 9, lockpin 10 that have the fore shaft and is used for carrying out spacing locking and two sets of dogs and cardboard that release the locking to lockpin 10, in first gear locking position, install the first dog 1 on first pivot A and install the first cardboard 2 intermeshing on second pivot B, the first dog engaging portion 1-2 of first dog 1 with the first cardboard first gear engaging portion of first cardboard 2 is the circular arc design, makes two engaging portions closely laminating. Because of the presence of the first dog engaging portion 1-2 of the first dog 1, and the torque applied to the first dog 1 by the first dog torsion spring 1-1, the two engaging portions are more difficult to disengage, and the first card 2 cannot rotate clockwise, thereby effectively blocking the lock pin 10 from being disengaged upward. In the first gear locking position, the second locking claw 4 arranged on the second rotating shaft C is meshed with the second clamping plate 3 arranged on the second rotating shaft B, and the two meshing parts are of circular arc design, so that the two meshing parts are tightly attached. Due to the presence of the second claw engagement portion 4-2 of the second claw 4, together with the torque applied to the second claw 4 by the second claw torsion spring 4-1, the two engagement portions are more difficult to disengage, and the second card 3 cannot rotate counterclockwise, thereby effectively blocking the lock pin 10 from being pressed downward. In the first-gear locking position, the outward opening pull rod drives the first locking claw 1 to rotate clockwise against the force value of the first locking claw torsion spring 1-1, so that the first locking claw meshing part 1-2 of the first locking claw 1 is separated from the first clamping plate first-gear meshing part 2-2 of the first clamping plate 2, the locking of the first clamping plate 2 is released, meanwhile, due to the existence of a linkage structure, the first locking claw 1 rotates and drives the second locking claw 4 to rotate through the lower linkage pin 1-4, and the second locking claw torsion spring 4-1 rotates anticlockwise against the force value of the second locking claw torsion spring 4-1, so that the second locking claw meshing part 4-2 of the second locking claw 4 is separated from the second clamping plate first-gear meshing part 3-2 of the second clamping plate 3, and the locking of the second clamping plate 3 is released. When the first clamping plate 2 and the second clamping plate 3 are unlocked, the lock pin 10 pushes the first clamping plate 2 and the second clamping plate 3 to move downwards continuously, the first clamping plate 2 stops moving after being limited by the contact bottom plate 9, the second clamping plate 3 stops moving after being limited by the contact bottom plate 9, and the lock pin 10 stops moving. After the first clamping plate 2 stops moving, the first locking claw 1 returns under the action of the first locking claw torsion spring 1-1, the first locking claw meshing part 1-2 is meshed with the first clamping plate second gear meshing part 2-3 of the first clamping plate 2, the first clamping plate 2 is completely fixed, and the locking pin 10 is completely limited from falling off in the upward direction by the first clamping plate 2. After the second clamping plate 3 stops moving, the second locking claw 4 returns under the action of the second locking claw torsion spring 4-1, the second locking claw meshing part 4-2 is meshed with the second clamping plate second gear meshing part 3-3 of the second clamping plate 3, the second clamping plate 3 is completely fixed, and the second clamping plate 3 completely limits the locking pin 10 to be pressed in downwards.
