Description

Technical Field

[0001] This utility model relates to the field of automotive seat adjustment technology, specifically to a gap-eliminating device for an electric slide rail system for automotive seats. Background Technology

[0002] Car seats are not only an important part of a vehicle, but to improve driving and riding comfort, their position needs to be adjusted. The adjustment mechanism typically includes an upper sliding rail assembly and a lower sliding rail assembly. Because the upper and lower sliding rail assemblies must ensure smooth sliding, they cannot be perfectly matched, and they are prone to deformation after a period of use, resulting in gaps. This can cause abnormal noises or uneven sliding during adjustment, affecting the comfort of the vehicle.

[0003] Common gap-eliminating structures typically require two types: one to eliminate vertical gaps and the other to eliminate horizontal gaps. These structures are complex to set up and take up a lot of space. Utility Model Content

[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes a gap elimination device for an electric sliding rail system for automobile seats. It has a simple structure and can simultaneously eliminate gaps in the Z and Y directions.

[0005] To achieve the above objectives, this utility model provides a gap-eliminating device for an electric sliding rail system for automobile seats, including a pair of gap-eliminating components disposed on the bottom side of the upper rail body. Each gap-eliminating component includes a pair of gap-eliminating wheels and a rotating bracket. A pair of mounting lugs are vertically disposed on the bottom side of the upper rail body. The middle part of the rotating bracket is rotatably connected to the mounting lugs via a bracket shaft. The gap-eliminating wheels are mounted on both sides of one end of the rotating bracket via a rotating shaft. A rubber pad is disposed on the top of the other end of the rotating bracket. The rubber pad is used to abut against the upper rail body, and the bottom of the gap-eliminating wheels is suspended. The upper rail body is provided with clearance through holes corresponding to the two gap-eliminating wheels. The top of the gap-eliminating wheels is located outside the clearance through holes, and the outer sides of the two gap-eliminating wheels are provided with chamfers, which abut against the two sides of the lower rail groove.

[0006] In the above scheme: a pair of anti-detachment baffles extending into the groove are provided on both sides of the lower rail to prevent the gap-reducing wheel from sliding out of the groove of the lower rail.

[0007] In the above scheme: the anti-detachment guard extends obliquely upward into the groove and then bends horizontally to the upper part of the middle of the gap-eliminating wheel. The chamfer of the gap-eliminating wheel abuts against the inclined part of the anti-detachment guard. Extending to the middle of the gap-eliminating wheel can further ensure that the gap-eliminating wheel slides out of the groove of the lower rail.

[0008] In the above scheme: the gap-eliminating wheel of each group of gap-eliminating components is set near the end of the upper rail body.

[0009] In the above scheme: the rotating bracket is provided with a positioning groove for installing the rubber pad, which can pre-position the installation position of the rubber pad, improve the installation efficiency, and at the same time avoid affecting the adjustment effect of the support due to being too far forward or too far back.

[0010] In the above scheme: the rotating bracket is groove-shaped, and the diameter of the rotating bracket is the same as the width of the rubber pad. The groove-shaped rotating bracket serves as a positioning groove, eliminating the need for additional grooving. The structure is simple, and the two side walls of the groove can be used as mounting lugs for the gap-eliminating wheel shaft for installation.

[0011] In the above solution: the rubber pad has bolt holes and is fixed to the rotating bracket by bolts. Installation is stable and convenient.

[0012] In the above scheme: the bolt hole is a countersunk hole, so the bolt can be completely submerged in the countersunk hole, avoiding the bolt from colliding with the rubber pad, thereby avoiding the adjustment effect of the rubber pad.

[0013] In summary, the beneficial effects of this utility model are as follows: the rotating bracket can form a lever structure, with rubber pads and gap-eliminating wheels at both ends. The rubber pads are used to abut against the bottom side of the upper rail body. When the gap-eliminating wheel abuts against the top of the lower rail, it can be elastically adjusted to eliminate the vertical gap. The chamfer on the gap-eliminating wheel abuts against the groove of the lower rail. The inclined part of the chamfer can adjust the gap-eliminating wheel to be in the center position to eliminate the horizontal gap. Only one gap-eliminating component is needed to eliminate gaps in two directions. The design is ingenious, stable and reliable. Attached Figure Description

[0018] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0019] like Figures 1-4As shown, a gap-eliminating device for an electric sliding rail system for an automotive seat includes a pair of gap-eliminating components disposed on the bottom side of an upper rail body 6. Each gap-eliminating component includes a rotating bracket 1, rubber pads 2 disposed at the front and rear ends of the rotating bracket 1, and a pair of gap-eliminating wheels. A pair of mounting lugs are vertically disposed on the bottom side of the upper rail body 6, and the middle part of the rotating bracket 1 is rotatably connected to the mounting lugs 8 via left and right extending bracket shafts. The gap-eliminating wheels 3 are mounted on both sides of the rotating bracket 1 via rotating shafts, the rubber pads 2 are used to abut against the upper rail body 6, and the bottom of the gap-eliminating wheels 3 is suspended. The top of the gap-eliminating wheels 3 is located above the rotating bracket 1, and the bottom of the gap-eliminating wheels 3 is located below the rotating bracket 1. The upper rail body 6 is provided with clearance holes 7 corresponding to the two gap-eliminating wheels 3, and the top of the gap-eliminating wheels 3 is located outside the clearance holes 7.

[0020] A pair of anti-slip edges 9 extending into the slot are provided on both sides of the lower rail 5 to prevent the gap-reducing wheel 3 from sliding out of the slot of the lower rail 5. The anti-slip edges 9 extend obliquely upwards into the slot and then bend horizontally to the upper part of the middle of the gap-reducing wheel 3, blocking part of the space above the gap-reducing wheel 3, further ensuring that the gap-reducing wheel 3 can slide out of the slot of the lower rail 5. Furthermore, the outer sides of the two gap-reducing wheels 3 are provided with chamfers 10, which abut against the inclined parts of the anti-slip edges 9. The pair of anti-slip edges 9 are symmetrically arranged to ensure that the gap-reducing wheel 3 is centered, making the upper slide rail assembly 1 more stable when moving back and forth.

[0021] The gap-eliminating wheel 3 of each set of gap-eliminating components is set at the end of the upper rail body 6. Rolling wheels are set at both ends of the upper rail body 101. The rolling wheels and gap-eliminating wheels 3 enable the system to roll and move in the lower rail 5, which can effectively absorb installation errors. At the same time, the running resistance fluctuation of the upper rail body 101 is also very small, and the system operates smoothly with low noise.

[0022] To improve installation efficiency, the rotating bracket 1 is provided with a positioning groove for installing the rubber pad 2, which can pre-position the installation position of the rubber pad 2 and avoid affecting the adjustment effect due to being too far forward or too far back. In this embodiment, the rotating bracket 1 is groove-shaped, and the diameter of the rotating bracket 1 is the same as the width of the rubber pad 2. By using the groove-shaped rotating bracket 1 as a positioning groove, there is no need to open a separate groove, the structure is simple, and the side walls of the groove can be directly used as mounting lugs for the shaft of the gap-eliminating wheel 3 for installation.

[0023] The rubber pad 2 has bolt holes, which are then fixed to the rotating bracket 1 by bolts. Installation is stable and convenient. The bolt holes are countersunk, allowing the bolts to be fully inserted, preventing them from contacting the rubber pad 2 and thus ensuring its adjustment function.
