[0028] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Example 1

[0030] This embodiment provides a tiltable seat frame structure 2 for installation at the bottom of the seat assembly 1 (eg Figure 1 , Figure 2 As shown), the seat frame structure 2 includes a mounting frame 21, a support assembly and a drive mechanism 24 (as shown Figure 3 , Figure 4 , Figure 5 shown).

[0031] The seat assembly 1 is mounted on the mounting frame 21; the support assembly includes a rotating bracket 22 and a guide bracket 23, and guide shafts 211 are provided at both ends of the mounting frame 21, wherein the guide shaft 211 at the first end is rotatably connected to the rotating bracket 22, and a guide groove 231 is provided on the guide bracket 23, and the guide shaft 211 at the second end of the mounting frame 21 is inserted into the guide groove 231; the driving mechanism 24 is mounted on the guide bracket 23 to drive the mounting frame 21, so that the guide shaft 211 at the second end of the mounting frame 21 moves around the guide shaft 211 at the first end and in the guide groove 231, so that the seat assembly 1 is tilted laterally.

[0032] The core feature of the seat frame structure 2 is the "tiltable" design, that is, through the action of the driving mechanism 24, the second end guide shaft 211 of the mounting frame 21 rotates around the first end guide shaft 211, so that the seat as a whole produces a lateral tilt effect. Specifically, guide shafts 211 are respectively provided at both ends of the mounting frame 21, and are connected to the rotating bracket 22 and the guide bracket 23. The cooperation of the rotating bracket 22 and the guide bracket 23 enables the seat frame to tilt in a specific direction, so that the seat side wings are lowered and consistent with the height of the seating surface, thereby facilitating passengers to get on and off the vehicle. The entire operation process realizes the tilt function of the seat through precise mechanical design, which improves the application effect of the car seat in high-sitting vehicle models.

[0033] like Figure 6 As shown, the mounting frame 21 includes two cross beams 212 and two longitudinal beams 214 , wherein the cross beams 212 are perpendicular to the direction of travel of the vehicle, and the longitudinal beams 214 are parallel to the direction of travel of the vehicle, and the cross beams 212 and the longitudinal beams 214 are connected end to end to form a rectangular frame structure, and the guide shafts 211 are arranged at both ends of the longitudinal beams 214 .

[0034] The design of the mounting frame 21 is based on a rectangular frame structure, and is composed of two cross beams 212 and two longitudinal beams 214. The design of the rectangular frame makes the mounting frame 21 more stable when installing the seat, and has strong support and durability. The guide shaft 211 is set at both ends of the longitudinal beam 214, so that the entire seat frame can maintain balance when tilting, avoiding unstable factors when tilting. In addition, the rectangular frame can further reduce the weight of the structure by reasonably designing the size and material, so that the seat frame can maintain appropriate lightness while ensuring strength.

[0035] The rotating bracket 22 and the guide bracket 23 are both fixedly installed on the car, and the rotating bracket 22 and the guide bracket 23 are arranged left and right perpendicular to the forward direction of the car. The rotating bracket 22 is located on the inner side away from the car door, and the guide bracket 23 is located on the outer side close to the car door. The rotating bracket 22 and the guide bracket 23 not only support the movement of the seat frame 232, but also play a guiding role. The fixed installation of the rotating bracket 22 and the guide bracket 23 ensures the stability of the support assembly and avoids unnecessary offset or unstable mechanical response during the seat tilting process.

[0036] like Figure 7 As shown, the guide bracket 23 includes a bracket body 233, the bottom surface of the bracket body 233 is a T-shaped structure, and mounting seats are arranged at both ends of the bracket body 233, and the mounting seats have vertical plates, and the guide grooves 231 are arranged on the vertical plates. The T-shaped bottom surface increases the stability of the bracket, so that it can withstand greater forces without deformation during the tilting process. The guide grooves 231 on the vertical plates provide a clear motion track for the guide shaft 211 of the mounting frame 21, ensuring that the frame always moves along the correct path during the tilting process.

[0037] The guide groove 231 is an arc groove, and the center of the arc groove coincides with the axis of the guide shaft 211 at the first end of the mounting frame 21. The arc design of the guide groove 231 is to enable the guide shaft 211 of the mounting frame 21 to slide along a smooth and continuous track during movement. By aligning the center of the arc groove with the axis of the first end guide shaft 211, it is ensured that the seat frame always maintains a stable angle and movement path during the tilting process. This design helps to avoid the deviation of the seat movement and ensure the accuracy of each tilting angle.

[0038] like Figure 8 As shown, the driving mechanism 24 includes a worm gear motor assembly 241 and a worm 242. A support seat 232 is provided on the frame body 233. The motor of the worm gear motor assembly 241 is rotatably mounted on the support seat 232. The worm 242 is inserted into the worm gear motor assembly 241 and meshes with the worm wheel of the worm gear motor assembly 241. One end of the worm 242 is hinged to the mounting frame 21.

[0039] The worm gear motor assembly 241 drives the movement of the worm 242 by rotating, and the worm 242 is hinged with the mounting frame 21 to realize the tilting of the seat. The cooperation between the worm gear motor assembly 241 and the worm 242 ensures the high efficiency and stability of the driving process. The meshing of the worm 242 and the worm wheel provides a large torque and has high durability. By reasonably designing the installation position of the support seat 232, the entire drive mechanism 24 can provide accurate and lasting power output during the tilting process of the seat.

[0040] A fixing plate 213 is installed on the inner side of the longitudinal beam 214 of the mounting frame 21, and one end of the worm 242 has an ear plate. The ear plate and the fixing plate 213 are rotatably connected by a pin shaft, thereby reducing the deviation caused by the loose connection between the fixing plate 213 and the ear plate, and ensuring smooth and stable movement during the seat tilting process.

[0041] Example 2

[0042] This embodiment provides a method for adjusting the tiltable seat frame structure 2, comprising:

[0043] Driven by the worm gear motor assembly 241, the motor rotates relative to the support base 232, and the outer end of the worm 242 swings downward;

[0044] Under the action of the worm 242 , the second end guide shaft 211 of the mounting frame 21 slides downward around the first end guide shaft 211 and along the guide groove 231 , thereby driving the outer side of the seat assembly 1 to tilt downward.

[0045] The method makes the seat tilting process more efficient and stable through the precise matching of the worm gear motor assembly 241 and the worm 242. Compared with the traditional mechanical seat adjustment method, the adjustment method of the present invention can greatly improve the convenience and accuracy of seat adjustment and enhance the user experience of the passengers.

[0046] In a specific implementation, the tilt angle of the seat can be controlled by adjusting the rotation speed of the worm motor and the gear ratio of the worm 242, and the shape and size of the guide groove 231 can be optimized according to the requirements of different vehicle models to achieve the best tilt effect.

[0047] Example 3

[0048] This embodiment provides a vehicle, including the tiltable seat frame structure 2 as described in Embodiment 1.

[0049] By integrating the seat frame structure 2 into the vehicle, it is possible to effectively improve the convenience of passengers getting on and off the vehicle in high-sitting vehicles. This design meets modern automobile requirements for comfort, safety and ease of operation, and enhances the overall sense of technology and modernity of the vehicle.

[0050] During the implementation process, the appropriate electric seat adjustment system can be selected according to the design requirements of different models, and intelligent adjustment can be performed in combination with the vehicle control system, so that the seat can automatically adjust the tilt angle according to actual needs.

[0051] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
