Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle door reinforcement plates, in particular to a vehicle rear door hinge reinforcement plate. Background Art

[0002] The function of the automobile rear door hinge reinforcement plate is to be welded inside the automobile rear door for assembling the rear door hinge, that is, the rear door hinge is connected to this component for load bearing.

[0003] At present, in order to improve the overall strength of the reinforcement plate, designers are committed to achieving this goal through sophisticated structural design. For example, the Chinese utility model patent document with announcement number CN215552482U records a design of a car rear door hinge reinforcement plate. Although the design includes multiple components such as a single fixed frame, four curved plates, two vertical plates, two horizontal plates and a single ring, it still has certain shortcomings in practical applications. Specifically, the four curved plates in the design are distributed at the four corners of the rectangular fixed frame. Although this layout enhances the stability of the structure to a certain extent, the connection between the curved plate and the fixed frame and the vertical plate is prone to cause stress concentration. Stress concentration is a problem that needs to be avoided in structural design because it affects the stability and durability of the reinforcement plate, and may cause structural damage and performance degradation in long-term use. In addition, the layout between the various structural components in the design is relatively scattered, and an effective whole is not formed. This decentralized design may not be effective enough in resisting external forces and cannot better disperse and reduce stress concentration.

[0004] Therefore, it is very necessary to invent a kind of reinforcement plate that is used for the hinge of automobile rear door. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a hinge reinforcement plate for a rear door of an automobile, comprising a reinforcing rib plate, a sealing plate, a pull rod and a back plate, wherein sealing plates are fixedly installed on both sides of the reinforcing rib plate, a pull rod is fixedly installed between the two sealing plates, and a back plate is fixedly installed outside the sealing plate;

[0006] The reinforcing rib plate includes a reinforcing frame, an inner diameter support body, a fixed seat, an inner ring support body and a support frame. Sealing plates are fixedly installed on both sides of the reinforcing frame, the inner diameter support body is fixedly installed inside the reinforcing frame, and fixed seats are installed at three points inside the inner diameter support body. The inner ring support body is fixedly installed on the three fixed seats, and the support frame is fixedly installed inside the inner ring support body.

[0007] Preferably, the reinforcement frame is a rectangular body, and the inner diameter support body fixedly installed inside the reinforcement frame is an elliptical structure, and the inner diameter support body is made of high-strength spring steel.

[0008] Preferably, the inner ring support body is a triangular structure, and the triangle of the inner ring support body is fixedly installed inside the inner diameter support body through the fixing seat.

[0009] Preferably, the support frame is an "X"-shaped structure, and the four end faces of the support frame are flush with the inner wall of the inner ring support body. The gap between the inner ring support body and the support frame allows the pull rod to pass through. The four pull rods are distributed at four points around the support frame, and the two ends of the pull rod are respectively fixedly connected to the sealing plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The rectangular design of the reinforcing frame of the utility model and the elliptical inner diameter support body installed inside make the overall structure extremely strong and stable.

[0019] As attached Figure 1 To Attachment Figure 3 As shown:

[0020] The utility model provides a reinforcement plate for a rear door hinge of an automobile, comprising a reinforcement rib plate 1, a sealing plate 2, a pull rod 3 and a back plate 4, wherein the sealing plates 2 are fixedly installed on both sides of the reinforcement rib plate 1, the pull rod 3 is fixedly installed between the two sealing plates 2, and the back plate 4 is fixedly installed outside the sealing plate 2. At this time, the design makes the entire reinforcement plate structure stable and can effectively disperse and withstand the stress from the rear door hinge of the automobile.

[0021] The reinforcing rib plate 1 includes a reinforcing frame 11, an inner diameter support body 12, a fixing seat 13, an inner ring support body 14 and a supporting frame 15. The sealing plates 2 are fixedly installed on both sides of the reinforcing frame 11, the inner diameter support body 12 is fixedly installed inside the reinforcing frame 11, and the fixing seats 13 are installed at three points inside the inner diameter support body 12. The inner ring support bodies 14 are fixedly installed on the three fixing seats 13, and the supporting frame 15 is fixedly installed on the inner side of the inner ring support body 14.

[0022] Embodiment 1:

[0023] Specifically, the reinforcement frame 11 is a rectangular body, and the inner diameter support body 12 fixedly installed on the inner side of the reinforcement frame 11 is an elliptical structure. The inner diameter support body 12 is made of high-strength spring steel. This design enables the inner diameter support body 12 to have both sufficient strength and certain elasticity, and can better adapt to and disperse stress.

[0024] Specifically, the triangle of the inner ring support body 14 is fixedly installed inside the inner diameter support body 12 through the fixing seat 13. The fixing seat 13 is an arc-shaped structure. The arc surface of the fixing seat 13 matches the inner diameter of the inner diameter support body 12, which can ensure that the fixing seat 13 is stably installed inside the inner diameter support body 12. The inner ring support body 14 is a triangular structure, which makes the inner ring support body 12 have excellent stability.

[0025] Specifically, the support frame 15 is an "X"-shaped structure, and the four end faces of the support frame 15 are flush with the inner wall of the inner ring support body 14. This design not only ensures the stability of the support frame 15, but also allows the tie rod 3 to easily pass through the gap between the inner ring support body 14 and the support frame 15. Four tie rods 3 are distributed around the support frame 15 at four points, and the two ends of the tie rod 3 are fixedly connected to the sealing plate 2 respectively, so that the tie rod 3 can effectively connect the two sealing plates 2 and enhance the stability of the entire reinforcement plate.

[0026] Embodiment 2:

[0027] First, the hinge of the rear door of the car will be subjected to various forces during the opening and closing process, which may cause the hinge to loosen, deform or even break. In order to enhance the strength and stability of the hinge, this reinforcement plate is designed and installed. The reinforcement frame 11 is the basic structure of the entire reinforcement rib plate 1 and provides basic support. The inner diameter support body 12 is installed inside the reinforcement frame 11. Since it is made of high-strength spring steel, it can not only withstand large stress, but also undergo a certain elastic deformation when subjected to external force, thereby effectively absorbing and dispersing stress. The inner ring support body 14 inside the inner diameter support body 12 has a triangular structure that makes it have good stability and can effectively support and strengthen the inner diameter support body 12. The arc structure of the fixing seat 13 matches the inner diameter of the inner diameter support body 12, ensuring that the inner ring support body 14 can be stably installed in an appropriate position. The support frame 15 is an "X"-shaped structure and is installed on the inner side of the inner ring support body 14. This design not only increases the stability of the structure, but also allows the pull rod 3 to easily pass through the gap between the inner ring support body 14 and the support frame 15. The two ends of the pull rod 3 are respectively fixedly connected to the two sealing plates 2 to form a stable structural frame, thereby enhancing the overall stability of the entire reinforcement plate. When the rear door of the car is opened and closed, the force on the hinge will be transmitted to the reinforcement plate. The reinforcement plate can effectively disperse and absorb these forces through the internal reinforcement rib plate 1 structure, especially the synergistic effect of the inner diameter support body 12, the inner ring support body 14 and the support frame 15, to prevent the hinge from being damaged by excessive stress. At the same time, the presence of the sealing plate 2 and the back plate 4 further enhances the rigidity and stability of the reinforcement plate, enabling it to better withstand the force from the hinge.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
