[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-5 The utility model provides a high-strength bracket installed on the backrest of the rear seat of an automobile, including a main board body 1, a process hole 2 is penetrated in the middle position of the main board body 1, a rivet nut 3 is penetrated on the main board body 1 and on the front and rear ends of the left side of the process hole 2, a limiting groove 4 is opened at the front and rear ends of the left side of the main board body 1, a narrowing groove 5 is provided on the right side of the main board body 1, a curved surface 6 is provided on the right side of the upper surface of the main board body 1, a slot 7 is provided between the right side of the main board body 1 and the curved surface 6, a reinforcing surface 8 is provided at the lower end of the curved surface 6 and on the right side of the main board body 1, a reinforcing rib 9 is provided on the upper surface of the main board body 1 at a position corresponding to the slot 7, and a bending surface 10 is provided at the lower end of the reinforcing surface 8.
[0017] When in use, a process hole 2 is opened on the main board body 1, which reduces the weight of the overall structure and improves the structural stress. The rivet nut 3 is fixed to the corresponding position on the main board body 1 through the riveting process, and a limiting groove 4 is set on the left side of the main board body 1. The main board body 1 is positioned on the backrest frame through the limiting groove 4. The overall bracket structure is set to the corresponding position of the backrest frame by passing the rivet nut 3 through the bolt, and a narrowing groove 5 is set on the right side of the main board body 1. While reducing the weight of the overall structure, the width of the reinforcement profile 8 is reduced to reduce the reinforcement profile 8 and other Structural interference, a curved surface 6 is set on the right side of the main board body 1, so that a slot 7 is formed between the right side of the main board body 1 and the curved surface 6, the slot 7 can be connected with other components, and the reinforcing surface 8 is connected to the main board body 1, and a bending surface 10 is set at the lower end of the reinforcing surface 8, so that the lower end of the reinforcing surface 8 forms an arc structure, so that the reinforcing surface 8 and the bending surface 10 can be spliced and connected with other components, and a reinforcing rib 9 is set on the right side of the main board body 1, while enhancing the strength of the main board body 1 itself, the connection strength between the curved surface 6 and the main board body 1 is enhanced.
[0018] There are two rivet nuts 3, and the front and rear ends of the two rivet nuts 3 are respectively close to the main board body 1 at the same distance. The distance between the front end rivet nut 3 and the left side of the main board body 1 is greater than the distance between the rear end rivet nut 3 and the left side of the main board body 1. By using two non-corresponding rivet nuts 3, the main board body 1 can be fixed to the backrest frame by two screws, and the displacement meter can be prevented from loosening.
[0019] The width of the main board body 1 is narrowed at the position of the card slot 7, and the width of the reinforced profile 8 is consistent with the width of the card slot 7. The main board body 1 is narrowed at the position of the card slot 7 to reduce interference with other components.
[0020] The plane where the bending profile 10 is located is parallel to the plane where the main board body 1 is located. By arranging the bending profile 10 in parallel with the main board body 1, the flatness of the overall structure is ensured.
[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
