[0028] It should be noted that the following detailed description is exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. Furthermore, it should be understood that the use of the term "including", as well as other like terms, has the same meaning.

[0029] Embodiment 1

[0030] The embodiment proposes a side-tilting seat frame structure 2, which is installed at the bottom of a seat assembly 1 (as shown in Figure 1 , Figure 2 The seat frame structure 2 includes a mounting frame 21, a support assembly, and a driving mechanism 24 (as shown in Figure 3 , Figure 4 , Figure 5 .

[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, both ends of the mounting frame 21 are provided with guide shafts 211, wherein the guide shaft 211 at the first end is rotationally connected with the rotating bracket 22, the guide bracket 23 is provided with a guide slot 231, and the guide shaft 211 at the second end of the mounting frame 21 is inserted into the guide slot 231; the driving mechanism 24 is installed 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 slot 231, so as to make the seat assembly 1 laterally tilt.

[0032] The core feature of the seat frame structure 2 is the "side-tilting" design, that is, through the action of the driving mechanism 24, the guide shaft 211 at the second end of the mounting frame 21 rotates around the guide shaft 211 at the first end, so that the whole seat tilts laterally. Specifically, the mounting frame 21 is provided with guide shafts 211 at both ends, and is connected with 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 side wings of the seat are lowered to be consistent with the height of the seating surface, thereby facilitating the passengers to get on and off the vehicle. The whole operation process realizes the side-tilting function of the seat through precise mechanical design, and improves the application effect of the automobile seat in high-sitting-position vehicles.

[0033] As shown in Figure 6 The mounting frame 21 includes two cross beams 212 and two longitudinal beams 214, the cross beams 212 are perpendicular to the direction of vehicle travel, the longitudinal beams 214 are parallel to the direction of vehicle travel, 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, which 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, with stronger support and durability. The guide shaft 211 is arranged at both ends of the longitudinal beam 214, so that the entire seat frame can maintain balance when tilted, avoiding instability factors when tilted. In addition, the rectangular frame can further reduce the weight of the structure by reasonable design of size and material, so that the seat frame can maintain appropriate light weight while ensuring strength.

[0035] The rotating bracket 22 and the guide bracket 23 are 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, avoiding unnecessary deviation or unstable mechanical response during the tilting of the seat.

[0036] As shown in Figure 7 The guide bracket 23 includes a bracket body 233, the bottom surface of the bracket body 233 is a T-shaped structure, and the two ends of the bracket body 233 are provided with mounting seats having vertical plates, and the guide slot 231 is arranged on the vertical plate. The T-shaped bottom surface increases the stability of the bracket, so that it can withstand a larger force without deforming during tilting. The guide slot 231 on the vertical plate provides a clear movement track for the guide shaft 211 of the mounting frame 21, ensuring that the frame always moves along the correct path during tilting.

[0037] The guide slot 231 is an arc-shaped slot, and the center of the arc-shaped slot coincides with the axis of the first end guide shaft 211 of the mounting frame 21. The arc-shaped design of the guide slot 231 is to make the guide shaft 211 of the mounting frame 21 slide along a smooth and continuous track during movement. By coinciding the center of the arc-shaped slot 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 tilting. This design helps to avoid deviation of the seat movement and ensures the accuracy of the tilting angle each time.

[0038] As shown in Figure 8 The drive mechanism 24 includes a worm gear motor assembly 241 and a worm 242, the bracket body 233 is provided with a support seat 232, the motor of the worm gear motor assembly 241 is rotatably installed on the support seat 232, the worm 242 is inserted into the worm gear motor assembly 241 and meshes with the worm of the worm gear motor assembly 241, and one end of the worm 242 is hinged with the mounting frame 21.

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

[0040] The inside of the longitudinal beam 214 of the mounting frame 21 is provided with a fixed plate 213, and one end of the worm 242 is provided with an ear plate. The ear plate and the fixed plate 213 are connected by a pin shaft, which reduces the deviation caused by the loose connection between the fixed plate 213 and the ear plate, and ensures the smoothness and stability of the movement during the reclining of the seat.

[0041] Embodiment 2

[0042] The embodiment provides an adjusting method of the reclining seat framework structure 2.

[0043] Under the driving of the worm gear motor assembly 241, the motor rotates relative to the support seat 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 incline downward.

[0045] The method realizes the efficient and stable reclining process of the seat through the precise cooperation of the worm gear motor assembly 241 and the worm 242. Compared with the traditional mechanical seat adjusting mode, the adjusting method can greatly improve the convenience and accuracy of seat adjustment, and improve the use experience of the occupant.

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

[0047] Embodiment 3

[0048] The embodiment provides a vehicle comprising the reclining seat framework structure 2 as described in embodiment 1.

[0049] By integrating the seat framework structure 2 into the vehicle, the convenience of the occupant getting on and off the vehicle of the high sitting position vehicle can be effectively improved. The design meets the requirements of modern automobiles for comfort, safety and operation convenience, and enhances the overall sense of technology and modernity of the vehicle.

[0050] In the implementation process, the seat electric adjustment system suitable for the design requirements of different vehicle models can be selected, and intelligent adjustment is carried out in combination with the vehicle-mounted control system, so that the seat can automatically adjust the inclination angle according to the actual needs.

[0051] The above describes the specific embodiments of the application in combination with the drawings, but is not a limitation on the protection scope of the application. It should be understood by those skilled in the art that various modifications or changes made by those skilled in the art on the basis of the technical solutions of the application without creative labor are still within the protection scope of the application.
