DETAILED DESCRIPTION

[0027] The following will refer to the accompanying drawings and preferred embodiments to illustrate the implementation of the technical solution of the utility model. Those skilled in the art can easily understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the utility model. It should be understood that the preferred embodiments are only for illustrating the utility model, not for limiting the scope of protection of the utility model.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0029] This embodiment proposes a rear seat backrest lock bracket structure, such as Figure 1 and Figure 2 As shown, it includes a box-shaped member 1, and the box-shaped member 1 is formed by partially bending a sheet member, that is, each box-shaped member 1 is formed by one sheet member, and there is no need to weld and combine multiple sheet members, and there is no need to introduce additional sheet members, which improves the fault tolerance and achieves lightweight.

[0030] The box-shaped component 1 includes a top surface 11, a first side surface 12, a second side surface 14 and a third side surface 13. The first side surface 12, the second side surface 14 and the third side surface 13 are all bent downward relative to the top surface 11, and the two sides of the second side surface 14 are respectively welded to the first side surface 12 and the third side surface 13, so that when the box-shaped component 1 is installed on the installation plane of the external mechanism, a cavity structure can be formed between it and the external mechanism, thereby improving the overall rigidity.

[0031] In this embodiment, first flanges 121 are provided on both sides of the first side surface 12, and the second side surface 14 and the third side surface 13 are respectively located on both sides of the first side surface 12, and are connected to the second side surface 14 and the third side surface 13 through the first flanges 121. The two first flanges 121 are respectively welded to the inner sides of the second side surface 14 and the third side surface 13, so that the box-shaped member 1 is a self-welding member to form a box member.

[0032] In this embodiment, the second side surface 14 is provided with a second flange 141 extending outward, and the top surface 11 is provided with a third flange 111 extending outward. The second flange 141 and the third flange 111 are parallel to the bottom surface of the box-like member 1, and the second flange 141 and the third flange 111 are arranged continuously. In this embodiment, on the bottom surface of the box-like member 1, the second flange 141 and the third flange 111 are arranged circumferentially along the bottom surface of the box-like member 1, and there is no gap between the second flange 141 and the third flange 111, which is in a continuous state. When the bottom of the box-like member 1 is connected to the mounting surface of the external component, the second flange 141 and the third flange 111 are both connected to the mounting surface of the external component, thereby improving the mounting strength.

[0033] The third side surface 13 in this embodiment is provided with a fourth flange 131 extending outward, and the fourth flange 131 is parallel to the bottom surface of the box-shaped member 1. In this embodiment, the fourth flange 131, the second flange 141 and the third flange 111 are all arranged circumferentially along the bottom surface of the box-shaped member 1, and all three are parallel to the bottom surface. The box-shaped member 1 is welded to the mounting surface of the external mechanism through the second flange 141, the third flange 111, the fourth flange 131 and the fifth flange 122, and the fifth flange 122 is arranged at the bottom of the first side surface 12.

[0034] The top surface 11 in this embodiment has a weight-reducing hole 113 and a harness installation hole 112 , and the first side surface 12 is also provided with a harness installation hole 123 , so that one part can be used to install multiple harnesses.

[0035] In this embodiment, the box-shaped part 1 has a larger stamping depth than the integrally formed box part, which will cause problems of difficulty in forming and defects in forming during manufacturing. At the same time, higher grade materials must be used for stamping to alleviate the problem of difficulty in forming, which will result in higher costs. This embodiment achieves the function of a box part in the form of self-welding, forms the first flange 121 by stamping, and spot welds the first flange 121 with its own second side 14 and third side 13 to achieve the purpose of forming a whole. Self-welding parts greatly reduce the difficulty of stamping and can use lower grade materials to achieve the purpose of cost reduction, making the parts more economical.

[0037] The rear seat backrest lock bracket structure includes a top surface 11, which is provided with two grooves. The two straight parts of the lock 2 are respectively embedded in the two grooves. The width of the groove is slightly larger than the diameter of the straight part. The lock 2 is fixedly connected to the box-shaped member 1 by welding the straight part and the groove, which fits the installation of the lock and provides pre-positioning, making the positioning of the lock 2 faster. At the same time, the gap formed by the groove and the lock 2 provides space for carbon dioxide shielded welding, making the welding more complete and the weld more reliable. At the same time, the weld can also be flush with the top surface 11, making the parts more beautiful and having the advantage of firm welding.
