Embodiment 1

[0059] Such as Figure 1 to Figure 8 As shown, the present invention discloses a car seat slide rail mechanism, including a lower slide rail 1, an upper slide rail 2, a locking and unlocking assembly and an operating assembly. The operation component controls the car seat slide rail mechanism to enter the locked state or the unlocked state through the locking and unlocking component, and the lower rail 1 and the upper rail 2 cannot slide relative to each other in the locked state. Can slide relatively in the unlocked state;

[0060] The side of the down rail 1 is provided with a plurality of locking grooves 1a arranged at intervals along the extending direction of the down rail 1, and the locking grooves 1a are notches with openings facing downward; for example: figure 1 In the shown embodiment, the locking groove 1a is arranged on the left side of the sliding rail 1, but the present invention does not rule out that the locking groove 1a is arranged on the right side of the s...

Embodiment approach

[0074] The top surface of the lock claw 4 is provided with a guide slot 4a and a limit claw 4-3; the lock claw bracket 5 is also provided with a guide pin 5-1 and a limit member 5-2;

[0075] The guide pin 5-1 is inserted into the guide slot 4a, so that: when the lock claw 4 rotates downward or upward around the lower edge 5a1 of the lock claw bracket support hole 5a, the lock claw 4 Rotate along the guide pin 5-1;

[0076] The limiting claw 4-3 extends into the limiting hole 5-2a of the limiting member 5-2, so that: when the car seat slide rail mechanism is in the unlocked state, the limiting member 5 -2 restricting the downward movement of the limiting claw 4-3, limiting the locking claw 4 to stop rotating downward around the lower edge 5a1 of the supporting hole 5a of the locking claw bracket;

[0077] When the car seat slide rail mechanism is in the locked state, the control handle lower part 3-2 of the control handle 3 abuts against the inner side wall of the top surface...

Embodiment 3

[0080] On the basis of the above-mentioned embodiment two, the present embodiment three also adopts the following preferred implementation modes:

[0081] The connection mode between the back-moving spring 6 and the locking claw 4 and the locking claw bracket 5 is as follows:

[0082] The return spring 6 is a torsion spring composed of a first hook 6-1, a straight section 6-2, a curved section 6-3 and a second hook 6-4;

[0083] The top surface of described locking pawl 4 is also provided with back-moving spring installation groove 4b; Described locking pawl support 5 is also provided with hook 5-3 and back-moving spring supporting part 5-4;

[0084] The first hook 6-1 is hooked to the hook 5-3, the straight section 6-2 is supported on the return spring supporting member 5-4, and the second hook 6-4 snapped into the return spring installation groove 4b.

[0085] Therefore, the present invention can make the structure of the locking and unlocking assembly more compact, and on...

Abstract

The invention discloses an automobile seat slide rail mechanism. A locking and unlocking assembly is formed by adopting a control handle, a locking claw, a locking claw support and a reset spring, andunder the control of an operation assembly, the switching of the mechanism between a locking state and an unlocking state can be realized; and as locking claw supporting bosses of the locking claw maintain to support on the lower edges of locking claw support supporting holes during the switching between the locking and unlocking states, the locking claw can rotate along the lower edges of the locking claw support supporting holes, so that the unlocking and locking motion of the locking and unlocking assembly can be more flexible, the active force applied by the operation assembly can be smaller, and therefore, the mechanism has advantages of being flexible in locking and unlocking and small in required active force; and the friction and impact force between the locking claw and a lower slide rail and an upper slide rail are relatively small, so that the problems of abnormal noise of automobile seat slide rail mechanisms generated by mutual friction and collision during locking and unlocking can be solved, and therefore, the mechanism is small in friction and collision strength during locking and unlocking and has no abnormal noise.

Description

technical field [0001] The invention relates to an automobile seat slide rail mechanism, which belongs to the technical field of automobile seats. Background technique [0002] The slide rail mechanism is an essential and important part of most car seats. It provides the possibility for the front and rear adjustment of the car seat, and can effectively improve the distribution and utilization of the front and rear space in the car. [0003] Most of the slide rails currently on the market have a single structure and are not very innovative, which limits the possibility of different manufacturers producing slide rails. [0004] Most manual slide rail mechanisms may produce abnormal noise due to the mutual friction and collision between slide rail components when adjusting the slide rail. On the one hand, it will cause wear of the slide rail components and reduce the service life of the slide rail. It brings bad sensory experience to customers, reduces customers' expectations ...
