[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0020] Example:

[0021] The specific implementation process of the utility model: the vehicle seat slide rail locking mechanism, such as Figure 1-Figure 4 As shown, it includes a cover shell 1, a trigger plate 7, a pressure plate 4, a rivet 2, a rivet pin 3, a telescopic spring 11 and a limit block 5; the telescopic spring 11 is fixedly arranged in the cover shell 1, the cover shell 1 is slidably connected to the pressure plate 4, the rivet pin 3 and the rivet 2, the pressure plate 4 is fixedly connected to the telescopic spring 11, the rivet pin 3 is fixedly connected to the pressure plate 4 and the trigger plate 7, and the limit block 5 is fixedly connected to the cover shell 1.

[0022] When the upper and lower slide rails are to be unlocked, the operator pulls up the unlocking handle, the unlocking handle will press the unlocking bracket downward, the unlocking bracket will abut against the top surface of the trigger plate 7, the unlocking bracket will press the trigger plate 7 downward, the trigger plate 7 will move downward with the rivet pin 3 and the pressure plate 4, the pressure plate 4 will compress the telescopic spring 11, the downward movement of the trigger plate 7 will release the lock on the upper and lower slide rails, the upper slide rail can slide on the lower slide rail, and then the operator releases the unlocking handle, the unlocking bracket returns to its original position, the telescopic spring 11 will push the pressure plate 4 upward, the pressure plate 4 will move upward with the rivet pin 3 and the trigger plate 7, the trigger plate 7 will The upper slide rail and the lower slide rail are locked again; through holes 9 are provided on both sides of the top of the cover shell 1, and the rivet 2 is slidably connected to the through holes 9. When installing the automobile seat slide rail locking mechanism of the utility model, the rivet 2 is first passed through the through hole 9 and the upper slide rail, and then the rivet 2 is riveted and fixed on the upper slide rail. A limiting groove 13 is provided on the pressure plate 4, and the limiting block 5 can prevent the pressure plate 4 from moving upward away from the cover shell 1. The limiting groove 13 corresponds to the position of the limiting block 5. The height of the top surface of the rivet pin 3 is lower than the height of the top surface of the pressure plate 4, so that the upper slide rail part directly above the rivet pin 3 does not need to open a large hole to avoid it, thereby improving the strength of the upper slide rail.

[0023] like Figure 2 and Figure 4 As shown, a groove 10 is provided on the pressure plate 4 , a boss 12 is fixedly provided in the cover shell 1 , the groove 10 is matched with the boss 12 , the top end of the telescopic spring 11 is fixed in the groove 10 , and the bottom end is provided outside the boss 12 .

[0024] The groove 10 and the boss 12 can respectively limit the upper and lower ends of the telescopic spring 11 to limit the left and right shaking of the telescopic spring 11. The boss 12 can also limit the pressing plate 4 when the pressing plate 4 moves downward.

[0025] like Figure 1 and Figure 2 As shown, a guide rod 8 is fixedly provided at the bottom end of the cover shell 1, and the trigger plate 7 is slidably connected to the guide rod 8.

[0026] The guide rod 8 can guide the catch plate 7 when the catch plate 7 moves up and down.

[0027] like Figure 1 and Figure 2 As shown, there are two guide rods 8 , and the two guide rods 8 are symmetrically arranged along the center line of the housing 1 .

[0028] The two guide rods 8 can limit the two ends of the catch plate 7 to prevent the catch plate 7 from rotating when it moves up and down.

[0029] like Figure 1 and Figure 3 As shown, a protrusion 6 is fixedly provided on the side wall of the housing 1 .

[0030] There are two protrusions 6, which are respectively arranged on two opposite side walls of the cover shell 1. When the unlocking bracket abuts against the top surface of the detent plate 7, the two opposite inner sides of the unlocking bracket will abut against the two protrusions 6 respectively. The two protrusions 6 can prevent the unlocking bracket from tilting and can also form a limit for the unlocking bracket.

[0031] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion shall fall within the protection scope of the present invention.
