Problems solved by technology
[0004] In the prior art, the solution of the fixed connection between the unlocking handle and the unlocking lever has the following problems: first, when the unlocking handle is assembled, it needs to be connected with the unlocking levers of the sliding rails on both sides through rivets, the assembly process is complicated, the number of parts is large, and the unlocking The connection between the handle and the unlocking lever is arranged on the outside of the slide rail for riveting assembly; second, the unlocking handle and the unlocking lever are rigidly fixed, and the manufacturing error of the unlocking handle will be completely transferred to the unlocking lever, because the opening size of the unlocking handle is large , that is, the distance between the two slide rails is relatively large, so the upper and lower errors at the two ends of the unlocking handle are relatively large. The problem of unlocking the unlocking lever in advance; third, because the unlocking mechanism is arranged in the inner slide rail cavity, and the space in the inner slide rail cavity is limited, the movement space of the unlocking lever is limited, so the unlocking empty stroke is relatively small, combined with the error of the unlocking handle Cumulatively, the risk of premature unlocking of one side slide rail is more likely to occur

Embodiment Construction
[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Words such as "first" and "second" mentioned in this article are only for the convenience of describing two or more structures or components with the same or similar structure and / or function, and do not represent any order and / or importance. some special limit.
[0031] Herein, the direction of the unlocking lever 1 close to the middle of the inner slide rail 01 is the inner end, and the side of the unlocking lever 1 close to the end of the inner slide rail 01 is the outer end. One end of the connecting portion 21 inserted into the inner sliding rail 01 is the inner end, and the end connected with the handle portion 22 is the outer end.
[0032] Please refer to Figure 1-Figure 5 , figure 1 It is a structural s...

The invention discloses an unlocking mechanism of a seat slide rail. The unlocking mechanism comprises an unlocking rod (1) and an unlocking handle (2), the unlocking rod (1) is of a U-shaped structure and is arranged in an inner slide rail (01), the inner end of the unlocking rod (1) is positioned above a locking mechanism (03), the middle part of the unlocking rod (1) is hinged to the inner slide rail (01), the unlocking rod (1) can rotate around a hinged part, the unlocking mechanism further comprises an elastic component (3), and a limiting piece (A) is arranged at the outer end of the unlocking rod (1). The connecting part (21) of the unlocking handle (2) is inserted between the unlocking rod (1) and the limiting piece (A), and the elastic part is clamped in the middle of the bottom wall of the connecting part (21) and provides upward acting force, so that a gap is formed between the inner end of the connecting part (21) and the bottom wall of the unlocking rod (1). The unlocking handle (2) can rotate around the limiting piece (A) and tightly presses the elastic component (3) until the connecting part (21) abuts against the unlocking rod (1) and rotates synchronously. The invention provides a seat slide rail. The process can be simplified, and the risk of unlocking in advance is avoided.
Description
technical field [0001] The invention relates to the technical field of vehicle seats, in particular to an unlocking mechanism of a seat slide rail and the seat slide rail. Background technique [0002] The seat slide rail is a device that connects the seat pan and the car floor to realize the front and rear adjustment of the seat, so that passengers can adjust the seat to the most comfortable position according to their needs. [0003] In the prior art, in an unlocking mechanism of a seat slide rail, the unlocking lever and the unlocking handle are connected together by rivets. When the unlocking handle is lifted up, the unlocking handle drives the unlocking lever to rotate around the center of rotation, and the other end drives down to lock mechanism to realize the unlocking of the inner and outer slide rails in the seat slide rail. [0004] In the prior art, the solution of the fixed connection between the unlocking handle and the unlocking lever has the following problem...
