However, the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosed content of the present utility model more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as "fixedly provided on" another element, it can be directly on the other element or there can be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0030] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0031] For the embodiment, please refer to the attached Figure 1-8 , an automobile seat mounting frame, comprising an automobile seat cushion frame 10, a sliding frame 20 is connected to the bottom end of the automobile seat cushion frame 10, and a backrest frame 30 is connected to one side of the automobile seat cushion frame 10;

[0032] The sliding frame 20 includes sliding seats 21 connected to both sides of the bottom of the automobile seat cushion frame 10, a sliding track 22 slidably connected to the sliding seats 21, and a support frame 23 connected to the lower surface of the sliding track 22.

[0033] Specifically, please refer emphatically to the attached Figure 1 and 2 , the longitudinal section of the first frame body 231 is L-shaped, and the cross section of the second frame body 232 is L-shaped;

[0034] Anti-detachment ear plates 22 are connected to both sides of the sliding seat 21. The anti-detachment ear plates 22 are located inside the anti-detachment groove plates 23, and the anti-detachment groove plates 23 are connected to both sides of the sliding track 22;

[0035] Ball bearing frames 228 are connected to the mutually remote sides of two adjacent anti-detachment ear plates 22, and a plurality of ball bearings 229 are embedded on the frames of the ball bearing frames 228;

[0036] It should be noted that in this embodiment, since the longitudinal section of the first frame body 231 is L-shaped, in this way, in cooperation with the vehicle frame, the cross-section of the second frame body 232 is L-shaped, thereby increasing the contact area between the second frame body 232 and the support frame 23, and further providing strong support;

[0037] Furthermore, the anti-separation ear plate 22 is inserted into the anti-separation groove plate 23, thereby preventing the sliding seat 21 from separating from the sliding track 22, so as to limit the stable sliding of the sliding seat 21 in the sliding track 22 and improve the stability of the vehicle seat cushion frame 10 when sliding;

[0038] Furthermore, the ball bearing frame 228 provides support for the balls 229. Through the cooperation of the ball bearing frame 228 and the balls 229, the friction caused by the relative sliding between the sliding seat 21 and the sliding track 22 is reduced, and the sliding stability of the sliding seat 21 is improved. Since the sliding seat 21 provides support for the vehicle seat cushion frame 10, the stability of the vehicle seat cushion frame 10 when sliding is improved.

[0039] Specifically, please refer to the attached Figure 3 and 4 , the longitudinal section of the sliding seat 21 is n-shaped;

[0040] A motor 31 is connected inside the frame body of the backrest frame 30. The output end of the motor 31 is connected to a speed reducer 32. The output end of the speed reducer 32 is connected to a rotating long shaft 33. The backrest frame 30 and the vehicle seat cushion frame 10 are connected through the rotating long shaft 33;

[0041] It should be noted that in this embodiment, since the sliding seat 21 is n-shaped, the anti-separation ear plates 22 on both sides of the sliding seat 21 can be inserted into the anti-separation groove plate 23;

[0042] Furthermore, the motor 31 drives the speed reducer 32 to work, and the speed reducer 32 drives the backrest frame 30 connected thereto, so that relative rotation occurs between the backrest frame 30 and the vehicle seat cushion frame 10.

[0043] Embodiment 2. Specifically, please refer to the attached Figure 1-8 , a vehicle seat skeleton structure, including a vehicle seat cushion frame 10, and a sliding frame 20 is connected to the bottom end of the vehicle seat cushion frame 10;

[0044] The sliding frame 20 includes sliding seats 21 connected to both sides of the bottom of the vehicle seat cushion frame 10, a sliding track 22 slidably connected to the sliding seats 21, and a support frame 23 connected to the lower surface of the sliding track 22;

[0045] The sliding track 22 and the sliding seat 21 are connected through a guiding mechanism 24.

[0046] Specifically, please refer to the appendix Figure 1 and 2 , the guiding mechanism 24 includes support seats 221 connected to both ends inside the rail body of the sliding rail 22. The two support seats 221 are connected by a guiding rod 222. A slider 223 is slidably connected to the outer surface of the rod body of the guiding rod 222, and the slider 223 is connected to the lower surface of the car seat frame 10;

[0047] Threads are provided at both ends of the guiding rod 222, and both ends of the guiding rod 222 are connected to the support seats 221 by threads;

[0048] Nuts 224 are threadedly engaged at both ends of the guiding rod 222, and one side of the nut 224 abuts against the support seat 221;

[0049] It should be noted that in this embodiment, the support seat 221 provides support for the guiding rod 222, and the guiding rod 222 provides guidance for the sliding of the slider 223, so that the car seat frame 10 slides stably in a straight line, improving the stability when the seat moves;

[0050] Furthermore, the guiding rod 222 is connected to the support seat 221 through the threads at both ends thereof. Through the setting of the support seat 221, the sliding distance of the slider 223 sliding on the guiding rod 222 is limited, preventing the sliding seat 21 from detaching from the sliding rail 22;

[0051] Furthermore, through the setting of the nut 224, the guiding rod 222 is locked on the support seat 221.

[0052] Specifically, please refer to the appendix Figure 5 and 6 , a sliding hole 2231 is provided on the block body of the slider 223, and the sliding hole 2231 is used for the guiding rod 222 to pass through;

[0053] Lubricating oil is filled between the hole body of the sliding hole 2231 and the outer surface of the rod body of the guiding rod 222;

[0054] The bottom end of the slider 223 is connected to a U-shaped sliding frame 225. Rolling beads 226 are embedded at the bottom end of the U-shaped sliding frame 225, and through holes 227 for the guiding rod 222 to pass through are provided on both sides of the U-shaped sliding frame 225;

[0055] It should be noted that in this embodiment, through the setting of the sliding hole 2231, the slider 223 can slide on the guiding rod 222;

[0056] Furthermore, through the setting of the lubricating oil, the friction when the slider 223 slides on the rod body of the guiding rod 222 is reduced;

[0057] Furthermore, the U-shaped carriage 225 provides support for the slider 223. By providing the rolling beads 226 at the bottom end of the U-shaped carriage 225, the friction during the sliding of the U-shaped carriage 225 and the sliding track 22 is increased.

[0058] The above provides an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made using the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
