Description

Technical Field

[0001] The utility model relates to the technical field of automobile anti-collision, in particular to an alloy profile anti-collision energy absorption structure. Background Technique

[0002] In the design and development of automobiles, crashworthiness design has always been a key point in automobile design, which is directly related to the life safety of passengers in a collision accident. The anti-collision beam at the front end of the automobile is the main energy absorption component. When a collision occurs, the energy absorption capacity of the anti-collision beam structure largely determines the crashworthiness of the automobile. The anti-collision beam structure generally consists of a main beam made of alloy profile, an energy absorption box, and a mounting plate connecting the automobile. Both the main beam and the energy absorption box can effectively absorb the collision energy during a low-speed collision of the vehicle, and minimize the damage to the longitudinal beam of the vehicle body caused by the impact force as much as possible.

[0003] In the existing alloy profile anti-collision energy absorption structure, when connecting the energy absorption box and the profile main beam, welding is usually used, and there is no additional protection measure around. Compared with the main body parts of the main beam and the energy absorption box, the fixation at the welding joint of the two is relatively weak. Without any protection, it is more likely to be damaged during a collision, resulting in the entire anti-collision energy absorption structure being unable to continue to be used. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an alloy profile anti-collision energy absorption structure to solve the technical problem that there is no auxiliary protection measure at the welding part of the energy absorption box and the main beam of the existing alloy profile anti-collision energy absorption structure, which is not conducive to improving the overall safety of the anti-collision energy absorption structure.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an alloy profile anti-collision energy absorption structure, including a profile main body, a welding seat and an energy absorption box. A welding protection mechanism is arranged at the connection part of the profile main body and the energy absorption box. The welding protection mechanism includes a U-shaped plate, a protection plate and a connecting plate. A wedge-shaped groove is opened on the U-shaped plate. A wedge-shaped block is arranged on one side inside the protection plate. A clamping block is arranged on the side wall of the protection plate. A through groove is opened on the protection plate.

[0006] By adopting the above technical scheme, the setting of the welding protection mechanism provides additional protection for the welding part through the structural design of the U-shaped plate, the protection plate and the connecting plate, and enhances the impact resistance of the connection part between the energy absorption box and the welding seat.

[0007] Further, two groups of the U-shaped plates and the protection plates are provided. Each group of the U-shaped plates and the protection plates has two, and the two U-shaped plates and the protection plates are symmetrically arranged.

[0008] By adopting the above technical solution and setting up two sets of U-shaped plates and protective plates, the connection parts between the energy absorption boxes and the welding seats on both sides are effectively protected, and the symmetrical design also provides structural balance.

[0009] Furthermore, there are two wedge blocks, which are symmetrically arranged, and the wedge blocks are engaged and slidably moved with the wedge grooves.

[0010] By adopting the above technical solution, the symmetrical arrangement of the wedge blocks can assist in better fixing the upper and lower sides of the protective plate to the U-shaped plate, thereby ensuring the stability of the protective plate fixed to the U-shaped plate.

[0011] Furthermore, the exterior of the energy absorption box is a large hexagonal structure, the interior of the energy absorption box is a small hexagonal structure, and the inner and outer hexagonal structures of the energy absorption box are connected via a support plate.

[0012] By adopting the above technical solution, the large hexagonal external structure and small hexagonal internal structure design of the energy absorbing box increase the strength and stability of the material. At the same time, the connection of the support plate enables the energy absorbing box to absorb and disperse energy more effectively when it is subjected to impact.

[0013] Furthermore, the through groove is a half hexagonal structure, and the through groove is connected to the space where the wedge block and the clamping block are located.

[0014] By adopting the above technical solution, the half hexagonal structure design of the through groove cooperates with the through groove on another protective plate in the same group to form a complete hexagonal structure, thereby completely wrapping the starting end of the energy absorption box close to the welding position.

[0015] Furthermore, a mounting seat is provided on one side of the energy absorption box, and threaded holes are provided on the mounting seat and the connecting plate.

[0016] By adopting the above technical solution, the design of the mounting seat and the threaded holes thereon provides a fast and reliable fixing method, so that the entire anti-collision energy absorption structure can be stably installed on the car body.

[0017] Furthermore, a reinforcing plate is arranged inside the profile body, and a plurality of the reinforcing plates are arranged, and the plurality of the reinforcing plates are evenly distributed, and a single reinforcing plate is cross-distributed.

[0018] By adopting the above technical solution, the provision of reinforcing plates, especially multiple uniformly distributed reinforcing plates, significantly improves the structural strength and rigidity of the profile body, which helps to better protect the profile body when the vehicle is hit.

[0019] Furthermore, a first rubber pad is provided on the inner side of the U-shaped plate, the first rubber pad is adapted to the U-shaped plate, and the first rubber pad is fixedly connected to the U-shaped plate.

[0020] By adopting the above technical solution, the setting of the first rubber pad, by virtue of its good elasticity, provides buffering for the connection between the U-shaped plate, the profile body and the top of the welding seat, reducing the damage to the welding part caused by direct impact.

[0021] Furthermore, a second rubber pad is arranged on one side of the clamping block. The second rubber pad is of a rectangular structure and is fixedly connected to the clamping block.

[0022] By adopting the above technical solution, the rectangular structure design of the second rubber pad provides additional protection and buffering between the clamping block and the side wall of the welding seat, reducing the direct impact of the impact force on the side wall of the welding seat.

[0023] Furthermore, a third rubber pad is arranged at the through groove. The third rubber pad is of a semi-hexagonal structure and is adapted to the outer wall of the energy absorption box.

[0024] By adopting the above technical solution, the setting of the third rubber pad, combined with the design of the through groove, forms a complete protection system, further improving the impact resistance of the welding part and ensuring the safety of the entire anti-collision energy absorption structure.

[0025] In summary, the present utility model mainly has the following beneficial effects:

[0026] 1. After the energy absorption box and the welding seat are welded, by setting the U-shaped plate, the protection plate and the through groove, the through grooves of the U-shaped plate and the protection plate are used to completely wrap the vicinity of the welding seat and the starting end of the energy absorption box, so as to completely wrap the welding part. The clamping blocks are abutted against both sides of the welding seat. When the entire anti-collision energy absorption structure of the alloy profile is impacted, the welding protection mechanism can be used to assist in absorbing part of the oscillation, avoiding the direct impact of the external impact on the welding part, thereby improving the overall safety of the anti-collision energy absorption structure to a certain extent.

[0027] 2. By setting the first rubber pad, the second rubber pad and the third rubber pad, the first rubber pad, the second rubber pad and the third rubber pad made of rubber have good elasticity and can well absorb and disperse the impact force. When the vehicle is impacted externally, each rubber pad can assist the anti-collision energy absorption structure and the welding protection mechanism in absorbing part of the oscillation, reducing the impact of the oscillation on the protected part, thereby further improving the safety.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0034] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0035] Embodiment 1:

[0036] An anti-collision energy absorption structure for alloy profiles, as Figures 1 - 4 shown, includes a profile main body 1, a welding seat 2 and an energy absorption box 3. A welding protection mechanism 6 is provided at the connection part of the profile main body 1 and the energy absorption box 3. The welding protection mechanism 6 includes a U-shaped plate 601, a protection plate 604 and a connecting plate 610. A wedge-shaped groove 602 is opened on the U-shaped plate 601. A wedge-shaped block 605 is provided on one side inside the protection plate 604. A clamping block 606 is provided on the side wall of the protection plate 604. A through groove 607 is opened on the protection plate 604. The setting of the welding protection mechanism 6, through the structural design of the U-shaped plate 601, the protection plate 604 and the connecting plate 610, provides additional protection for the welding part and enhances the impact resistance of the connection part between the energy absorption box 3 and the welding seat 2. The combined use of the wedge-shaped groove 602 and the wedge-shaped block 605 provides an adjustable fixing method, ensuring that the entire welding protection mechanism 6 can be installed after welding is completed, and at the same time can also ensure that the protection plate 604 is more stably fixed on the U-shaped plate 601, improving the stability of the overall structure.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4There are two groups of U-shaped plates 601 and protective plates 604, and each group of U-shaped plates 601 and protective plates 604 is provided with two. The two U-shaped plates 601 and protective plates 604 are symmetrically arranged. The arrangement of the two groups of U-shaped plates 601 and protective plates 604 ensures that the parts where the energy absorption box 3 on both sides is connected to the welding seat 2 are effectively protected. The symmetrical design also provides structural balance. Each group of two symmetrical U-shaped plates 601 and protective plates 604 can provide protection on both sides of the welding part, ensuring comprehensive protection of the welding part.

[0038] See also Figure 4 There are two wedge blocks 605, and the two wedge blocks 605 are symmetrically arranged. The wedge blocks 605 are engaged and slidable with the wedge grooves 602. The symmetrical arrangement of the wedge blocks 605 can assist the upper and lower sides of the protective plate 604 to be better fixed to the U-shaped plate 601, ensuring the stability of the protective plate 604 fixed on the U-shaped plate 601. The engagement and sliding arrangement of the wedge blocks 605 and the wedge grooves 602 makes the installation of the protective plate 604 and the U-shaped plate 601 relatively simple and quick, and the connection is firm. By later using the connecting plate 610 to fix the two protective plates 604 in the same group, the two U-shaped plates 601 in the same group are indirectly fixed.

[0039] See also Figure 2 The outside of the energy absorbing box 3 is a large hexagonal structure, and the inside of the energy absorbing box 3 is a small hexagonal structure. The inner and outer hexagonal structures of the energy absorbing box 3 are connected by a support plate. The large hexagonal outer structure and the small hexagonal inner structure design of the energy absorbing box 3 increase the strength and stability of the material. At the same time, the connection of the support plate enables the energy absorbing box 3 to absorb and disperse energy more effectively when it is subjected to impact. The design of the inner and outer hexagonal structures also helps to improve the deformation resistance of the energy absorbing box 3, and maintain the integrity of the structure even under high-intensity impact.

The half-hexagonal structure design of the through slot 607 cooperates with the through slot 607 on another protective plate 604 in the same group to form a complete hexagonal structure, thereby completely wrapping the starting end of the energy absorption box 3 near the welding position, and is connected with the space where the wedge block 605 and the card block 606 are located, providing an effective way to utilize space, so that the protective plate 604 can more tightly wrap the welding seat 2 near the welding position and the starting end of the energy absorption box 3 at the same time.

A single reinforcing plate 5 is cross-distributed. The arrangement of the reinforcing plates 5, especially the multiple evenly distributed reinforcing plates, significantly improves the structural strength and rigidity of the profile body 1, which helps to better protect the profile body 1 when the vehicle is hit. The cross-distribution design of the reinforcing plates 5 further enhances the stability inside the profile body 1, so that the entire anti-collision energy absorption structure can more effectively disperse and absorb energy when subjected to impact.

The arrangement of the first rubber pad 603, using its good elasticity, provides a buffer for the connection between the U-shaped plate 601 and the profile body 1 and the top of the welding seat 2, reducing the damage to the welding part caused by direct impact. The fixed connection between the first rubber pad 603 and the U-shaped plate 601 ensures that when the vehicle is hit, the first rubber pad 603 can play an effective role, thereby helping to improve the safety of the anti-collision energy absorption structure.

The rectangular structure design of the second rubber pad 608 provides additional protection and buffering between the block 606 and the side wall of the welding seat 2, reducing the direct impact of the impact force on the side wall of the welding seat 2. The fixed connection between the second rubber pad 608 and the block 606 ensures that the second rubber pad 608 will not deviate when the vehicle is hit, so that it can stably play a role in buffering vibration.
