[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 , the utility model provides an embodiment: a seat frame, comprising: a U-shaped tube 1 for driving backrest, a headrest rod bracket 2 is provided on one side of the U-shaped tube 1 for driving backrest, an inner side panel 3 of the driving seat frame is provided on one side of the headrest rod bracket 2, and two inner side panels 3 of the driving seat frame are provided, the U-shaped tube 1 for driving backrest, the headrest rod bracket 2 and the inner side panel 3 of the driving seat frame are connected by a skeleton edge rod, an anti-submarine tube 4 is provided between the two inner side panels 3 of the driving seat frame, the headrest rod bracket 2 includes a bracket plate body 5, side support plates 7 are bent on both sides of the bracket plate body 5, an upper bending plate 6 is bent at the top of the bracket plate body 5, and a lower support plate 9 is bent at the bottom end of the bracket plate body 5, reinforcing ribs 8 are provided at the front ends of the bracket plate body 5 and the side support plate 7, and several reinforcing ribs 8 are provided, and a side line reinforcement seat 10 is provided at the connection between the bracket plate body 5 and the lower support plate 9, and two side line reinforcement seats 10 are provided.

[0022] Since side support plates 7 are bent on both sides of the bracket plate body 5, they provide support for the headrest and both sides of the back of the person, thereby improving the overall gathering effect and the overall wrapping performance. The person is less likely to be displaced by inertia, thereby improving safety and stability. The reinforcing ribs 8 are used to increase the hardness of the bracket plate body 5 and the side support plates 7, making them less likely to be damaged by force. The edge reinforcement seat 10 strengthens the connection between the bracket plate body 5 and the lower support plate 9, thereby improving safety.

[0023] See also Figure 2 、 3A second through hole 12 is provided on the surface of the bracket plate body 5 near the top end, and a first through hole 11 is provided on the surface of the bracket plate body 5 near the bottom end. A hole reinforcement seat 13 is protruded between the periphery of the first through hole 11 and the second through hole 12 and the bracket plate body 5, which has a reinforcement effect on the first through hole 11 and the second through hole 12, making it less likely for the edges to crack and be damaged, thereby improving safety and protection.

[0024] See also Figure 1 、 4 The inner side panel 3 of the driver's seat frame includes a side mounting plate 14 and an end connecting plate 15. A connecting hole 16 is provided on one end surface of the end connecting plate 15, and a pipe hole 17 is provided on one end surface of the side mounting plate 14, and the anti-submarine tube 4 is inserted into the pipe hole 17. A buckle 18 is provided on the surface near the center of the side mounting plate 14. The anti-submarine tube 4 is U-shaped, with high ends and low middle. The two ends of the anti-submarine tube 4 are respectively inserted into the pipe holes 17 of the two inner side panels 3 of the driver's seat frame, which has an anti-falling effect. Since the anti-submarine tube 4 is U-shaped, with high ends and low middle, it has a limiting effect on the legs of the personnel. When the vehicle suddenly brakes or collides, it prevents the occupant's hips and legs from sliding forward, thereby reducing the damage to the occupant caused by the collision and improving safety.

[0025] See also Figure 1 The U-shaped tube 1 of the driver's seat back includes a tube body 19, and flattening grooves 20 are provided on both side surfaces of the center of the tube body 19. The flattening grooves 20 facilitate the insertion of the external headrest column, which is not easy to protrude outward. This is the existing technology.

[0026] Working principle: When in use, since both sides of the bracket plate body 5 are bent with side support plates 7, they support the headrest and both sides of the back of the person, improve the overall folding effect, improve the overall wrapping performance, and the person is not easy to cause position deviation due to inertia, thereby improving safety and stability. In addition, the top end of the bracket plate body 5 is bent with an upper bending plate 6, and the bottom end of the bracket plate body 5 is bent with a lower support plate 9, which strengthens the upper and lower ends. The hardness of the bracket plate body 5 and the side support plates 7 is improved by relying on the reinforcing ribs 8, and it is not easy to be damaged by force. The bracket plate body 5 and the lower support plate 9 are reinforced by the side reinforcement seat 10. The connection of the support plate 9 has a reinforcing effect and improves safety. The two ends of the anti-submarine tube 4 are respectively inserted into the tube holes 17 of the two inner side panels 3 of the driver's seat frame to prevent falling. Since the anti-submarine tube 4 is U-shaped, with high ends and low middle, it has a limiting effect on the legs of the person. When the vehicle suddenly brakes or collides, it prevents the occupant's buttocks and legs from sliding forward, thereby reducing the damage to the occupant caused by the collision and improving safety. The U-shaped tube 1 of the driver's backrest, the headrest rod bracket 2 and the inner side panel 3 of the driver's seat frame are connected by a skeleton edge rod, which is an existing seat skeleton connection technology.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
