[0007] Furthermore, the sound-absorbing sleeve comprises a sound-absorbing layer and a mounting frame, the mounting frame is slidably connected to the mounting block, and the sound-absorbing layer is fixed on the outside of the mounting frame.

[0008] Furthermore, a telescopic groove is provided on the mounting block, a U-shaped positioning frame is slidably arranged in the telescopic groove, and a telescopic spring is fixedly arranged, the telescopic spring is fixedly connected to the positioning frame, and the positioning frame is slidably connected to the mounting frame.

[0009] Furthermore, the number of the positioning frames and the number of the telescopic springs are both two, and the two positioning frames are respectively arranged at both side ends of the mounting block.

[0010] Furthermore, a pressure plate is fixedly arranged on the positioning frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model adopts a silencer sleeve and a mounting block to silence the upper slide rail when it collides with the lower slide rail, thereby avoiding the generation of abnormal noise, improving the experience of people riding in the car, and solving the problem that the upper slide rail and the lower slide rail may collide and produce abnormal noise when the car is on a relatively bad road section;

[0013] 2. The utility model adopts a telescopic spring, a positioning frame and a pressing plate to facilitate the positioning of the silencer sleeve on the mounting block. BRIEF DESCRIPTION OF THE DRAWINGS

[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: a car seat slide rail with abnormal sound elimination function, such as Figure 1-Figure 3 As shown, it includes an upper slide rail 1, a lower slide rail 2 and a retaining frame 5; a steel ball 6 is fixedly set on the retaining frame, the upper slide rail 1 and the lower slide rail 2 are both slidably connected to the retaining frame 5, and both abut against the steel ball 6, a mounting block 3 is fixedly set on the upper slide rail 1, a silencer sleeve is set on the mounting block 3, and the silencer sleeve is set on the inner side of the lower slide rail 2.

[0022] When the car bumps, the lower slide rail 2 is fixed on the car body, the upper slide rail 1 will move up and down, the bottom end of the upper slide rail 1 is close to the top end of the lower slide rail 2, the silencer sleeve will move upward with the bottom end of the upper slide rail 1 and collide with the top end of the lower slide rail 2, which can prevent the generation of abnormal noise.

[0023] like Figure 4 As shown, the sound-absorbing sleeve includes a sound-absorbing layer 4 and a mounting frame 7 , the mounting frame 7 is slidably connected to the mounting block 3 , and the sound-absorbing layer 4 is fixed on the outside of the mounting frame 7 .

[0024] The material of the sound-absorbing layer 4 can be plastic material, so as to prevent the sound-absorbing sleeve from colliding with the top of the lower sliding rail 2 and making abnormal noise.

[0025] like Figure 4 As shown, a telescopic groove 8 is provided on the mounting block 3, a U-shaped positioning frame 9 is slidably arranged in the telescopic groove 8, and a telescopic spring 10 is fixedly arranged, the telescopic spring 10 is fixedly connected to the positioning frame 9, and the positioning frame 9 is slidably connected to the mounting frame 7.

[0026] A positioning hole is provided on the mounting frame 7, and the upper end of the positioning frame 9 is slidably connected to the positioning hole. When the silencer sleeve is to be installed, the lower end of the positioning frame 9 is first pressed into the telescopic groove 8, and the upper end of the positioning frame 9 will enter the telescopic groove 8 together with the lower end of the positioning frame 9. The positioning frame 9 will compress the telescopic spring 10, and then the mounting frame 7 is inserted into the mounting block 3, so that the positioning hole is aligned with the upper end of the positioning frame 9, and then the squeezing of the lower end of the positioning frame 9 is released, and the telescopic spring 10 will push the upper and lower ends of the positioning frame 9 out of the telescopic groove 8 together, and the upper end of the positioning frame 9 will extend into the positioning hole to form the positioning of the mounting frame 7.

[0027] like Figure 4 As shown, the number of the positioning frames 9 and the number of the telescopic springs 10 are both two, and the two positioning frames 9 are respectively arranged at the two side ends of the mounting block 3 .

[0028] The two positioning frames 9 can position the two side ends of the installation frame 7 to improve the stability of the relative position between the installation frame 7 and the installation block 3.

[0029] like Figure 4 As shown, a pressing plate 11 is fixedly arranged on the positioning frame 9 .

[0030] The pressing plate 11 can facilitate personnel to press the lower end of the positioning frame 9 .

[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.
