AI Technical Summary
The existing car seat height adjustment mechanism will cause jittering and abnormal noise when bumping the road, and there will be abnormal noise when driving and lifting, mainly due to the gap between the fan-shaped tooth plate and the height adjustment device.
Add secondary teeth to the sector tooth plate and connect it to the sector tooth plate through rivets. The rubber spring supports the secondary teeth so that its tooth shape and the height adjuster are always close to each other, eliminating the gap between the teeth meshing.
By eliminating the tooth meshing gap, it effectively eliminates the abnormal noise when the seat is raised, improving the user experience.

Technical Field
[0001] The utility model relates to the technical field of automobile seats, in particular to a fan-shaped tooth plate mechanism for adjusting the height of an automobile seat. Background Art
[0002] Currently, the common way to achieve up and down height adjustment of seats on the market is: the four-bar linkage on the seat is connected to the fan-shaped toothed plate, and the height adjuster drives the fan-shaped toothed plate to adjust the four-bar linkage up and down to achieve up and down height adjustment of the seat.
[0003] However, the fan-shaped gear plate and the height adjuster are transmitted through the meshing of teeth. There is a certain gap between the teeth, combined with the manufacturing accuracy and easy assembly. This leads to the following problems in actual use: 1. There is shaking and abnormal noise on bumpy roads; 2. There is abnormal noise when driving and lifting (due to the reverse force of the reset torsion spring).
[0004] Therefore, in order to solve the above problems, a fan-shaped gear plate mechanism for adjusting the height of a car seat is proposed. Utility Model Content

[0006] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:
[0007] A fan-shaped tooth plate mechanism for adjusting the height of a car seat comprises a fan-shaped tooth plate assembly, wherein the fan-shaped tooth plate assembly is meshedly connected with a height adjuster, the fan-shaped tooth plate assembly comprises a fan-shaped tooth plate, auxiliary teeth, a rubber spring and a rivet, one end of the rubber spring abuts against the rivet, and the other end of the rubber spring abuts against the auxiliary teeth, so as to push the auxiliary teeth to always be in close contact with the height adjuster.
[0008] Furthermore, the tooth shape of the auxiliary teeth is consistent with the tooth shape of the sector-shaped tooth plate.
[0009] Furthermore, oblong holes are provided at both ends of the auxiliary teeth.
[0010] Furthermore, two of the rubber springs and two of the rivets are provided.
[0011] Furthermore, the sector-shaped tooth plate and the auxiliary tooth are connected by two rivets.
[0012] Furthermore, the two rubber springs are respectively located in the two oblong holes.
[0013] The beneficial effects of the utility model are as follows:
[0014] The utility model adds auxiliary teeth to the sector-shaped tooth plate, the auxiliary teeth are connected to the sector-shaped tooth plate through rivets, a rubber spring is placed between two oblong holes of the auxiliary teeth, one end of the rubber spring is supported by the rivet, and the other end pushes the tooth shape of the auxiliary teeth to always be in close contact with the height adjuster, thereby eliminating the gap in tooth meshing and achieving the effect of eliminating abnormal noise.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0021] In the description of the present invention, it should be understood that the terms up, down, front, back, left, right, top, bottom, inside, outside, etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0022] The examples are as follows:
[0023] See also Figure 1-4A fan-shaped tooth plate mechanism for adjusting the height of a car seat comprises a fan-shaped tooth plate assembly 1, which is meshed and connected with a height adjuster 2. The fan-shaped tooth plate assembly 1 comprises a fan-shaped tooth plate 11, auxiliary teeth 12, a rubber spring 13 and a rivet 14. The tooth shape of the auxiliary teeth 12 is consistent with the tooth shape of the fan-shaped tooth plate 11. Long circular holes are provided at both ends of the auxiliary teeth 12. Two rubber springs 13 and two rivets 14 are provided. The fan-shaped tooth plate 11 and the auxiliary teeth 12 are connected by two rivets 14. The two rubber springs 13 are respectively located in the two long circular holes. One end of the rubber spring 13 abuts against the rivet 14, and the other end of the rubber spring 13 abuts against the auxiliary teeth 12, so that the tooth shape of the auxiliary teeth 12 is always in close contact with the height adjuster 2, eliminating the gap in tooth meshing and achieving the effect of eliminating abnormal noise.
[0024] In summary: the utility model adds auxiliary teeth 12 to the sector tooth plate 11, the auxiliary teeth 12 are connected to the sector tooth plate 11 through rivets 14, and a rubber spring 13 is placed between the two oblong holes of the auxiliary teeth 12. One end of the rubber spring 13 is supported by the rivet 14, and the other end pushes the tooth shape of the auxiliary teeth 12 to always be in close contact with the height adjuster 2, thereby eliminating the gap in tooth meshing and achieving the effect of eliminating abnormal noise.
