DETAILED DESCRIPTION

[0039] The following is combined with Figure 1 —7 provides further details of this application.

[0040] The embodiment of the present application discloses a car seat adjustment mechanism.

[0041] Example 1:

[0042] Reference Figure 1 and Figure 2A car seat adjustment mechanism includes a slide rail fixed in the car, with a slide seat 1 slidably connected to the slide rail. The slide seat 1 is a rectangular plate that slides in a direction close to the steering wheel. A first drive assembly for driving the slide seat 1 to slide is fixed to the bottom of the slide seat 1. A rotating disk 3 for mounting the car seat is rotatably connected to the slide seat 1. The rotating disk 3 is in the shape of a disk, and a second drive assembly for driving the rotating disk 3 is fixed to the slide seat 1. The first drive assembly can be used to adjust the distance of the car seat from the steering wheel, and the second drive assembly can be used to control the rotation of the car seat. Therefore, by rotating the car seat when the user gets on and off the car, the user can get on and off the car more conveniently. A limit support ring 2 is fixed on the sliding seat 1, and the limit support ring 2 is coaxially arranged with the rotating disk 3. A support ring groove 8 is provided at the bottom of the rotating disk 3 for plugging with the limit support ring 2. By plugging and matching the support ring groove 8 with the limit support ring 2, not only can the position of the rotating disk 3 be limited, the shaking of the rotating disk 3 can be reduced, and the stability of the rotating disk 3 can be improved, but the rotating disk 3 can also be supported, thereby ensuring the strength of the support between the sliding seat 1 and the rotation and improving the stability of the adjustment mechanism.

[0043] The slide rail is composed of two sliding guide rails 6. The sliding guide rails 6 are provided with a sliding cavity 7 along the sliding direction of the sliding seat 1. The sliding cavity 7 is a rectangular cavity. The bottom of the sliding seat 1 is bolted with a sliding guide plate 5 that slides with the two sliding guide rails 6. The sliding guide plate 5 is inserted into the sliding cavity 7 and slides in the sliding cavity 7. A limiting flange 13 is integrally formed at the opening of the sliding cavity 7. The limiting flange 13 has an L-shaped cross-section and is fixed along the sliding direction of the sliding seat 1. The limiting flange 13 and the inner wall of the sliding guide rail 6 form a limiting groove 12. A limiting guide plate 14 is integrally formed at the end of the sliding guide plate 5 away from the sliding seat 1. The limiting guide plate 14 is S-shaped and plugs into the limiting groove 12. The sidewalls of the limiting guide plate 14 abut against the sidewalls of the limiting groove 12, thereby limiting the sliding guide plate 5 and reducing the shaking of the limiting guide plate 14, thereby improving the stability of the sliding seat 1. In addition, the combination of the limiting guide plate 14 and the limiting flange 13 can reduce the occurrence of the sliding guide plate 5 detaching from the sliding guide rail 6, thereby improving the stability of the sliding seat 1.

[0044] The first drive assembly includes a first drive member 15 fixed to the bottom of the sliding seat 1. The first drive member 15 is a dual-axis motor with a first drive shaft 16 installed within it. The first drive shaft 16 extends through both ends of the first drive member 15. Drive wheels 18 are fixed to both ends of the first drive shaft 16. The drive wheels 18 abut the bottom of the sliding cavity 7, thereby driving the sliding seat 1 to move. The sliding guide 5 is bolted to a limit plate 4. A fixed plate 17 is fixed between the two limit plates 4. The first drive member 15 is bolted to the fixed plate 17, thereby locking the first drive member 15. The limit plate 4 is provided with a limit hole 19 that engages with the first drive shaft 16 through which it can be inserted and pulled. The limit hole 19 can restrain the first drive shaft 16, improving the stability of the first drive shaft 16.

[0045] The second drive assembly includes a second drive gear 11 rotatably connected to the sliding seat 1. A positioning shaft is provided at the bottom of the rotating disk 3, and a second driven gear 9 is fixed to the positioning shaft and meshes with the second drive gear 11. A second drive member 10, which is a reduction motor, is bolted to the bottom of the sliding seat 1 and is used to drive the second drive gear 11. Attaching both the first and second drive members 15 and 10 to the base of the sliding seat 1 allows for more efficient use of the space within the adjustment mechanism, making it more suitable for use in vehicles with lower heights and enhancing ease of use.

[0046] The implementation principle of Example 1 is: when getting on the car, the second driving member 10 drives the car seat to rotate toward the side close to the car door, so that the seat can face the user. When the user sits on the car seat, the first driving member 15 drives the car seat to reset, thereby completing the user's getting on the car. Using such a design, users can get on and off the car more conveniently, and can sit on the car seat more comfortably, thereby improving the user's riding experience.

[0047] Example 2:

[0048] Reference Figure 5 and Figure 6A car seat adjustment mechanism differs from Example 1 in that a second drive assembly includes a limit slot 21 extending through the sliding seat 1. The limit slot 21 extends longitudinally along the sliding direction of the sliding seat 1. A driving wheel 24 is rotatably connected to the rotating disk 3, driving the rotation by a drive gear. A drive rack 22 meshing with the drive gear is integrally formed on the side of the limit slot 21 away from the rotation direction of the car seat. A limit wheel 23 is rotatably connected to the bottom of the rotating disk 3. The limit rotation is slidably connected within the limit slot 21. Under the action of the drive gear and drive rack 22, the limit shaft is constantly in contact with the side of the limit slot 21 closest to the rotation of the car seat, reducing contact between the limit wheel 23 and the drive rack 22. When the limiting wheel 23 is slidably connected to the limiting groove 21, it is used to limit the movement of the rotating disk 3. The driving gear cooperates with the driving rack 22, so that the rotating disk 3 can slide along the length of the limiting groove 21. The sliding seat 1 also has a limiting groove 28, which is connected to the limiting groove 21. The limiting wheel 23 slidably cooperates with the limiting groove 28. When the driving wheel 24 rotates to one side of the limiting groove 21, the movement of the driving wheel 24 is restricted. At this time, the rotating disk 3 is driven to rotate, causing the limiting wheel 23 to rotate into the limiting groove 28, thereby rotating the rotating disk 3. A third driving member 25 for driving the driving wheel 24 to rotate is fixed to the bottom of the rotating disk 3. The third driving member 25 is a reduction motor.

[0049] Two supporting sliders 20 are fixed to the bottom of the rotating disk 3. The two supporting sliders 20 are symmetrically arranged along the sliding direction of the rotating disk 3. Two supporting chutes 26 and supporting arc grooves 27 are provided on the sliding seat 1. The supporting chutes 26 and supporting arc grooves 27 are connected and provided, and the supporting sliders 20 abut against the bottom of the supporting chutes 26 or supporting arc grooves 27. The supporting chutes 26 are provided along the sliding direction of the rotating disk 3, and the supporting arc grooves 27 are provided along the rotation direction of the rotating disk 3, thereby achieving the function of supporting the rotating disk 3 and improving the stability of the rotating disk 3. The depth of the supporting chutes 26 gradually decreases as it approaches the steering wheel. Figure 7 A sliding inclined surface 29 is provided at the bottom of the supporting slider 20 and abuts against the supporting arc groove 27.

[0050] The implementation principle of Example 2 is: when the user gets on or off the car, the seat is moved away from the steering wheel and the car seat is driven down at the same time, so that the user can have a better riding experience. In addition, this application adopts a third driving member 25 to realize the sliding and rotation of the rotating disk 3, reduce the use of the driving structure, reduce the production cost of the adjustment mechanism, and improve the convenience of using the adjustment mechanism.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
