Abstract
Description
Technical Field
[0001] The utility model relates to an armrest box bracket. Background Art
[0002] The armrest box bracket is installed on the inner side of the car door, ensuring a more stable and aesthetic fit between the inner door panel and the armrest of the door trim. The existing armrest box bracket has square holes opened on the plate body, and then the rivet nut is passed through the square hole and riveted to the product by a riveting gun and a special tooling for positioning. Since the thickness of the plate body is relatively thin and prone to deformation, the process of riveting with the nut is difficult to ensure the perpendicularity and firmness between the nut and the product, and the thread is prone to deformation during the riveting process, resulting in quality problems such as poor assembly with the product. Summary of the Invention
[0003] The purpose of the utility model is to provide an armrest box bracket, which has better perpendicularity of the nut, no deformation of thin materials, etc., and greatly improves the product quality and production efficiency.
[0004] [[ID=1ó]]The technical solution provided by the utility model is: an armrest box bracket, including a bracket body, the bracket body is a steel plate body structure, and the middle part of the bracket body is connected into an L-shaped structure by a horizontal plate and a vertical plate; the lower end of the vertical plate has a lower folding plate bent towards the outer plate surface of the vertical plate; the end of the horizontal plate has an upper folding plate bent towards the outer plate surface of the horizontal plate; a round hole is opened on the horizontal plate, and a projection welding nut is welded at the round hole.
[0005] A circular installation through hole is provided on the upper folding plate, and an oval installation through hole is provided on the lower folding plate.
[0006] The bending angle between the lower folding plate and the vertical plate is 135 degrees; the bending angle between the upper folding plate and the horizontal plate is 135 degrees.
[0007] The structure of the utility model is simple and easy to process. The product and the nut are positioned by a positioning pin, and the nut is projection welded by a projection welding tooling. During the production process, the quality is stable, the perpendicularity is better, the thread is not deformed, the strength is better, and the control and inspection are easier; and it meets the product quality and assembly requirements. It can achieve high-quality, high-efficiency and low-cost output of the product. Brief Description of the Drawings
[0008] Figure 1 It is a structural schematic diagram of the utility model;
[0009] Figure 2 It is a three-dimensional schematic diagram of the utility model. Detailed Description of the Preferred Embodiment
[0010] See Figure 1 and Figure 2, the present utility model provides, including a support body 1, the support body 1 is a steel plate structure, the middle part of the support body 1 is connected into an L-shaped structure by a transverse plate 2 and a vertical plate 4; the lower end of the vertical plate 4 has a lower folding plate 5 bent towards the outer plate surface direction of the vertical plate 4; the right end of the transverse plate 2 has an upper folding plate 3 bent towards the outer plate surface direction of the transverse plate 2; a round hole 6 is provided on the transverse plate 2, and a projection welding nut 7 is welded at the round hole 6 for connecting with the door protection plate handle.
[0011] A circular mounting through-hole 8 is provided on the upper folding plate 3 for mounting and connecting with the inner door panel; an oval mounting through-hole 9 is provided on the lower folding plate 5 for mounting and connecting with the inner door panel.
[0012] The bending angle between the lower folding plate 5 and the vertical plate 4 is 135 degrees; the bending angle between the upper folding plate 3 and the transverse plate 2 is 135 degrees.
[0013] The structure of the present utility model is simple and easy to process. The product and the nut are positioned by a positioning pin, and the nut is projection welded by a conventional general projection welding tooling. The projection welding tooling has strong versatility and low cost; it can cooperate with an automatic nut conveyor to realize automatic projection welding and conveying. The welding process is stable and the welding strength is more guaranteed; moreover, during the welding process, the nut (thread) is not easily deformed and has better perpendicularity, greatly reducing the risk of insecure connection between the nut and the product and unsmooth assembly, and having higher production efficiency.
