Description

Technical Field

[0001] This utility model relates to the field of automotive parts installation technology, and in particular to an installation structure for the upper plate of the energy-absorbing box of the rear crossbeam of an automobile. Background Technology

[0002] The design of an energy-absorbing box typically includes components such as an upper plate, a lower plate, and a sealing plate. The upper plate of the energy-absorbing box in the rear crossbeam of a car is an important part of the car bumper system. Its main function is to absorb and disperse the impact force in the event of a collision, thereby protecting the vehicle body structure and the safety of passengers. The upper and lower plates of the energy-absorbing box are fitted and fixed together.

[0003] The existing automotive rear crossbeam energy-absorbing box upper plate lacks a limiting structure on its side during actual installation, which can easily lead to misalignment during installation and affect the normal use of the energy-absorbing box. In addition, the upper plate lacks a buffer structure at the end, which can easily cause damage during installation. This paper proposes an installation structure for the automotive rear crossbeam energy-absorbing box upper plate to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in the existing technology, this utility model proposes an installation structure for the upper plate of the energy-absorbing box of a car rear crossbeam. This structure solves the technical problems in the background technology where the upper plate of the energy-absorbing box of the car rear crossbeam lacks a limiting structure on its side during actual installation, which can easily lead to misalignment during installation and affect the normal use of the energy-absorbing box. In addition, the upper plate lacks a buffer structure at its end, which can easily cause damage during installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy-absorbing box upper plate mounting structure for a car rear crossbeam includes an energy-absorbing box upper plate. The lower front end of the energy-absorbing box upper plate has two first grooves. The two first grooves are respectively located near the side walls of the vertical sections on both sides of the energy-absorbing box upper plate. Each of the two first grooves is provided with a buffer mechanism. The buffer mechanism is provided with a U-shaped buffer pad. The U-shaped buffer pad is fitted onto the lower front end of the energy-absorbing box upper plate. Each of the opposite side walls of the vertical sections on both sides of the energy-absorbing box upper plate is provided with an interlocking tongue. Each of the opposite side walls of the two interlocking tongues is provided with a limiting mechanism.

[0007] Preferably, the buffer mechanism includes a buffer airbag fixedly connected to the top surface of the first groove and two first springs. The buffer airbag is located between the two first springs. The lower ends of the buffer airbag and the two first springs are fixedly connected to the same connecting block. The lower end of the connecting block is fixedly connected to the inner wall of the horizontal section of the U-shaped buffer pad.

[0008] Preferably, the interlocking tongue and the upper plate of the energy-absorbing box are integrally cast, and the connecting block and the U-shaped buffer pad are integrally formed.

[0009] Preferably, both the connecting block and the U-shaped buffer pad are polyurethane rubber products.

[0010] Preferably, the limiting mechanism includes two second grooves respectively disposed on the opposite sidewalls of two interlocking tongue pieces, two second springs fixedly connected to the inner walls of each of the second grooves, and the same arc-shaped pressure plate fixedly connected to the end of the two second springs on the same side away from the inner wall of the second groove. The upper and lower ends of the arc-shaped pressure plate are provided with limiting protrusions, and the top and bottom surfaces of the second grooves away from the second springs are provided with limiting slots. The two limiting protrusions are respectively movably inserted into the two limiting slots.

[0011] Preferably, the limiting protrusion and the arc-shaped pressure plate are integrally formed, and both the limiting protrusion and the arc-shaped pressure plate are corrosion-resistant alloy products.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By aligning the upper plate and lower plate of the energy-absorbing box and adjusting them to the appropriate position, the fitting tongue of the upper plate of the energy-absorbing box is aligned with the fitting groove of the lower plate and inserted. This causes several arc-shaped pressure plates to compress the second spring in the second groove under the limiting action of the limiting protrusion and the limiting slot. This effectively limits the upper plate and lower plate of the energy-absorbing box and makes the fitting tongue and fitting groove fit more tightly, preventing misalignment and ensuring the normal use of the energy-absorbing box.

[0014] 2. By connecting the upper plate and lower plate of the energy-absorbing box, the car bracket comes into contact with the U-shaped buffer pad, and the U-shaped buffer pad, together with the connecting block, compresses the buffer airbag and the first spring in the first groove, effectively providing buffer protection for the end of the upper plate of the energy-absorbing box and preventing damage during installation.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A mounting structure for an energy-absorbing box upper plate of a car rear crossbeam includes an energy-absorbing box upper plate 1. Two first grooves 2 are provided at the lower front end of the energy-absorbing box upper plate 1. The two first grooves 2 are respectively located near the vertical sidewalls on both sides of the energy-absorbing box upper plate 1. A buffer mechanism is provided in each of the two first grooves 2, and a U-shaped buffer pad 3 is provided on the buffer mechanism. The U-shaped buffer pad 3 is fitted onto the lower front end of the energy-absorbing box upper plate 1. The buffer mechanism includes a buffer airbag 5 fixedly connected to the top surface of the first groove 2 and two first springs 6. The buffer airbag 5 is located between the two first springs 6, and the lower ends of the buffer airbag 5 and the two first springs 6 are fixedly connected to the same... A connecting block 7 is fixedly connected at its lower end to the inner wall of the horizontal section of the U-shaped buffer pad 3. The fitting tongue 4 is integrally cast with the upper plate 1 of the energy-absorbing box. After the upper plate 1 of the energy-absorbing box is aligned with the lower plate of the energy-absorbing box (not shown in the figure), the car bracket and the U-shaped buffer pad 3 come into contact. The U-shaped buffer pad 3, in conjunction with the connecting block 7, compresses the buffer airbag 5 and the two first springs 6 in the first groove 2, effectively providing buffer protection for the end of the upper plate 1 of the energy-absorbing box and preventing damage during installation. The connecting block 7 and the U-shaped buffer pad 3 are integrally formed. Both the connecting block 7 and the U-shaped buffer pad 3 are polyurethane rubber products.

[0024] On the opposite sidewalls of the vertical sections on both sides of the energy-absorbing box upper plate 1, there are interlocking tongues 4. Each interlocking tongue 4 has a limiting mechanism on its opposite sidewall. The limiting mechanism includes two second grooves 8 respectively located on the opposite sidewalls of the two interlocking tongues 4. Two second springs 9 are fixedly connected to the inner walls of each of the second grooves 8. On the same side, the ends of the two second springs 9 furthest from the inner wall of the second groove 8 are fixedly connected to the same arc-shaped pressure plate 10. Limiting protrusions 11 are provided at both the top and bottom of the arc-shaped pressure plate 10. Limiting slots 12 are provided on the top and bottom surfaces of the second grooves 8 furthest from the second springs 9. The two limiting protrusions 11 are movably inserted into the two limiting slots 12, thus connecting the energy-absorbing box upper plate 1 with... After the lower plate of the energy-absorbing box (not shown in the figure) is aligned and adjusted to a suitable position, the fitting tongue 4 of the upper plate 1 of the energy-absorbing box is aligned with the fitting groove of the lower plate of the energy-absorbing box (not shown in the figure) and inserted. After the several arc-shaped pressure plates 10 are pressed against the inner wall of the fitting groove, the second spring 9 in the second groove 8 is compressed under the limiting action of the limiting protrusion 11 and the limiting slot 12. This effectively limits the upper plate 1 and the lower plate of the energy-absorbing box (not shown in the figure), thereby making the fitting tongue 4 fit more tightly with the fitting groove, preventing misalignment, and ensuring the normal use of the energy-absorbing box. The limiting protrusion 11 and the arc-shaped pressure plate 10 are integrally formed and are both corrosion-resistant alloy products.

[0025] In use, the upper plate 1 of the energy-absorbing box and the lower plate of the energy-absorbing box (not shown in the figure) are aligned and adjusted to a suitable position. Then, the fitting tongue 4 of the upper plate 1 is aligned with the fitting groove of the lower plate of the energy-absorbing box (not shown in the figure) and inserted. After the several arc-shaped pressure plates 10 are pressed against the inner wall of the fitting groove, the second spring 9 in the second groove 8 is compressed under the limiting action of the limiting protrusion 11 and the limiting slot 12. This effectively limits the upper plate 1 and the lower plate of the energy-absorbing box (not shown in the figure), so that the fitting tongue 4 and the fitting groove are more tightly connected, preventing misalignment and ensuring the normal use of the energy-absorbing box. After aligning the upper plate 1 and the lower plate of the energy-absorbing box (not shown in the figure), the car bracket and the U-shaped buffer pad 3 come into contact. The U-shaped buffer pad 3, together with the connecting block 7, compresses the buffer airbag 5 and the two first springs 6 in the first groove 2, effectively providing buffer protection for the end of the upper plate 1 of the energy-absorbing box and preventing damage during installation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
