Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a reinforcement structure for automotive front door hinges. Background Technology

[0002] With the advancement of technology and the rapid development of the automotive industry, vehicles have become a common means of transportation for families. The rigidity and strength of vehicle components, as important characteristics of vehicle quality, are related to both the safety performance of the vehicle and the reliability of the installation of automotive parts. The front door of a car connects the door to the car body frame through hinges and is an important installation point for the front door. It must meet both the strength requirements for door installation and the fatigue durability requirements of the front door. Therefore, the design of the front door hinge installation point of the car body is particularly important.

[0003] The front door hinge reinforcement structure is designed to improve the strength of the front door hinge mounting points and prevent the door from being unable to open or close. The hinge is fixed to the inner door panel and the hinge reinforcement structure with bolts, which improves the door's sag resistance and reduces residual deformation to some extent. Traditional hinge reinforcement structures typically design the upper and lower hinge reinforcement plates as a single piece, which results in low material utilization and is not conducive to vehicle weight reduction and lightweighting requirements.

[0009] Preferably, the right side of the second reinforcing plate extends rearward to form a zigzag welded edge that fits against the upper and lower sides of the inner door panel.

[0010] Preferably, the left and right sides of the hinge reinforcing plate extend outward to form a reinforcing member with an overall Z-shaped structure, and the reinforcing plate body and the second reinforcing plate are located at the top of the reinforcing member.

[0011] Preferably, the left end of the reinforcing member extends forward to form a lower welding edge, a middle welding edge, and an upper welding edge that are integrally W-shaped and fit against the top of the inner panel of the door.

[0012] Preferably, the notch formed between the middle welding edge and the upper welding edge is arc-shaped.

[0013] Preferably, the lower welding edge and the middle welding edge are welded to the inner panel of the car door, and the upper welding edge is welded to the outer waistline reinforcing plate and the inner panel of the car door.

[0014] Preferably, the hinge nut plate and the reinforcing plate body are welded along the bottom edge of the hinge nut plate.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 A car front door hinge reinforcement structure includes an inner door panel 1, a hinge reinforcement plate 2, a hinge nut plate 3, and an outer waistline reinforcement plate 4. The hinge reinforcement plate 2 is welded to the front side of the inner door panel 1, the hinge nut plate 3 is welded to the hinge reinforcement plate 2, and the outer waistline reinforcement plate 4 is welded to both the hinge reinforcement plate 2 and the inner door panel 1. The outer waistline reinforcement plate 4 absorbs some of the sagging stress of the door and further enhances the strength of the hinge mounting point. A hinge mounting hole is provided in the middle of the hinge reinforcement plate 1.

[0025] like Figure 2 As shown, the hinge reinforcement plate 2 includes a reinforcement plate body 21. The right side of the reinforcement plate body 21 has a 7-shaped plate structure. The corner of the 7-shaped structure provides a certain reinforcement to the hinge reinforcement plate 21. The right end of the reinforcement plate body 21 extends towards the side close to the inner door panel 1 to form a second reinforcement plate 22. The second reinforcement plate 22 is also provided with a process through hole 24. The right side of the second reinforcement plate 22 extends backward to form a zig-shaped welding edge 23 that fits vertically with the inner door panel 1. This zig-shaped structure facilitates the outflow of electrophoretic liquid and at the same time provides local reinforcement to the hinge reinforcement plate 2.

[0026] like Figure 2 As shown, the left and right sides of the hinge reinforcement plate 2 extend outward to form an integral Z-shaped reinforcement member. The reinforcement plate body 21 and the second reinforcement plate 22 are located at the top of the reinforcement member. This Z-shaped structure provides an overall reinforcement effect for the hinge reinforcement plate 2, which can effectively reduce residual deformation.

[0027] like Figure 2 As shown, the left end of the reinforcing member extends forward to form a W-shaped lower welding edge 201, a middle welding edge 202, and an upper welding edge 203 that fit together with the top of the inner door panel 1. The lower welding edge 201 and the middle welding edge 202 are welded to the inner door panel 1, and the upper welding edge 203 is welded to the outer waistline reinforcing plate 4 and the inner door panel 1, respectively. The gap formed between the middle welding edge 202 and the upper welding edge 203 is arc-shaped. This structure can better disperse the stress on the inner door panel of the hinge reinforcing plate.

[0028] like Figure 1-5 As shown, the hinge nut plate 3 and the reinforcing plate body 21 are welded along the bottom edge of the hinge nut plate 3, which can better resist the deformation at the door hinge mounting point.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
