Description

Technical Field

[0001] This invention specifically relates to an impact-resistant aluminum profile for automobile chassis. Background Technology

[0002] The application of aluminum profiles in automobile manufacturing is mainly concentrated in two aspects: body and chassis. Compared with traditional steel, aluminum profiles are lighter and have higher strength and rigidity, which can be used to strengthen the body structure and improve overall safety and torsional rigidity.

[0003] Existing aluminum profiles used in automobile chassis have relatively simple structures. When the car is moving, protrusions on the ground will directly contact the aluminum profiles of the chassis, causing significant impact damage. This makes it difficult to absorb the impact force and cannot effectively buffer instantaneous impacts, resulting in low safety and poor impact resistance. Therefore, we propose an impact-resistant aluminum profile for automobile chassis. Summary of the Invention

[0004] The purpose of this invention is to provide an impact-resistant aluminum profile for automobile chassis, so as to solve the problems mentioned in the background art, such as inconvenience in dissipating force and poor impact buffering effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an impact-resistant aluminum profile for automobile chassis, comprising:

[0006] A supporting aluminum profile is installed inside the vehicle body, and the lower end of the supporting aluminum profile has an arc-shaped surface that absorbs impact.

[0007] The first connecting block is slidably disposed on the supporting aluminum profile, and one end of the first connecting block is connected to the second connecting block, which is detachably connected to the vehicle body.

[0008] The first connecting block has an elastic component on its inner side that cushions the impact when the supporting aluminum profile is subjected to an impact.

[0009] Preferably, the supporting aluminum profile has an integrally formed flange, and the inner sidewall of the first connecting block has a sliding groove that matches the flange, and the sliding groove is stepped.

[0010] Preferably, the inner side of the supporting aluminum profile is provided with a reinforcing rib plate, and the cross-section of the reinforcing rib plate is "V" shaped.

[0011] Preferably, a reinforcing strip is fixed to the inner side of the reinforcing rib plate, and the outermost diameter of the reinforcing strip corresponds to the arc-shaped surface.

[0012] Preferably, the elastic component includes a transverse elastic element and a longitudinal elastic element, the longitudinal elastic element being fixed at both ends of the transverse elastic element and fixed to the first connecting block.

[0013] Preferably, one end of the first connecting block is provided with a second connecting part that cooperates with the vehicle body, and the other end of the first connecting block is fixed with a first connecting part that cooperates with the second connecting block.

[0014] Preferably, the second connecting block has the same shape as the first connecting block, and the second connecting block and the first connecting block are fixed together by bolts.

[0015] Preferably, the middle part of the supporting aluminum profile is lower than the height of both ends, and the upper surfaces of both ends of the supporting aluminum profile are flush.

[0016] Preferably, multiple elastic components are evenly distributed along one short side of the first connecting block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By incorporating supporting aluminum profiles, curved surfaces, a first connecting block, a second connecting block, and elastic components, this device prevents damage to the chassis from significant impacts from ground protrusions when the vehicle is moving. It can absorb and cushion impacts, improving the device's impact resistance. The device is easy to install, and the supporting aluminum profiles, first connecting blocks, or second connecting blocks can be replaced or maintained individually later. Furthermore, the inner side of the supporting aluminum profiles has reinforcing ribs to enhance the overall strength and impact resistance of the device. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 This invention provides a technical solution: an impact-resistant aluminum profile for automobile chassis, comprising:

[0029] Support aluminum profile 2 is installed inside the body body 1. The lower end of the support aluminum profile 2 has an arc-shaped surface 22 to absorb impact, so as to avoid the ground protrusions from causing large impact damage to the support aluminum profile 2.

[0030] The first connecting block 3 is slidably mounted on the supporting aluminum profile 2, and one end of the first connecting block 3 is connected to the second connecting block 4. The second connecting block 4 is detachably connected to the body body 1, which facilitates separate disassembly and maintenance in the future.

[0031] The first connecting block 3 has an elastic component 5 on its inner side that buffers the aluminum profile 2 when it is impacted, which facilitates better buffering of the impact and reduces damage from large impacts in an instant.

[0032] Preferably, the supporting aluminum profile 2 has an integrally formed flange 21, and the inner side wall of the first connecting block 3 has a groove 32 that matches the flange 21. The groove 32 is stepped, which makes it easier to reduce the large compression damage to the elastic component 5 through the stepped shape. At the same time, the groove 32 also makes it easier to install the supporting aluminum profile 2.

[0033] Preferably, a reinforcing rib plate 23 is provided on the inner side of the supporting aluminum profile 2. The reinforcing rib plate 23 has a "V" shaped cross section, which facilitates better strength. The "V" shaped design is also convenient to cooperate with the supporting aluminum profile 2 to form multiple spaces with triangular cross sections, thereby improving the stability of the support.

[0034] Preferably, a reinforcing strip 24 is fixed to the inner side of the reinforcing rib plate 23, and the outermost diameter of the reinforcing strip 24 corresponds to the arc-shaped surface 22, which facilitates better impact resistance.

[0035] Preferably, the elastic component 5 includes a transverse elastic element 51 and a longitudinal elastic element 52. The longitudinal elastic element 52 is fixed at both ends of the transverse elastic element 51 and is fixed to the first connecting block 3, which facilitates better buffering of impacts in different directions.

[0036] Preferably, one end of the first connecting block 3 is provided with a second connecting part 33 that cooperates with the vehicle body 1, and the other end of the first connecting block 3 is fixed with a first connecting part 31 that cooperates with the second connecting block 4, so as to facilitate installation and fixation.

[0037] Preferably, the second connecting block 4 has the same shape as the first connecting block 3, and the second connecting block 4 and the first connecting block 3 are fixed together by bolts.

[0038] Preferably, the middle part of the supporting aluminum profile 2 is lower than the height of both ends, and the upper surfaces of both ends of the supporting aluminum profile 2 are flush, which facilitates increasing the upper accommodating space of the supporting aluminum profile 2.

[0039] Preferably, multiple elastic components 5 are evenly distributed along one short side of the first connecting block 3, which facilitates better dispersion of impact force when subjected to impact.

[0040] The working principle and usage process of this invention are as follows: In use, the first connecting block 3 and the second connecting block 4 are slidably engaged with the supporting aluminum profile 2, and then placed inside the vehicle body 1 to fix the first connecting block 3, the second connecting block 4, and the vehicle body 1. When the vehicle body 1 moves, when the supporting aluminum profile 2 is impacted by a ground protrusion, part of the impact force can be dissipated through the arc surface 22. At the same time, the transverse elastic element 51 and the longitudinal elastic element 52 undergo elastic deformation, further buffering the impact force. The slide groove 32 is stepped to prevent the supporting aluminum profile 2 from being driven by the flange 2 under impact. When moving upwards, the transverse elastic element 51 and the longitudinal elastic element 52 are subjected to large compression deformation damage. The inner side of the supporting aluminum profile 2 has a reinforcing rib plate 23. The "V"-shaped reinforcing rib plate 23 combined with the supporting aluminum profile 2 forms multiple triangular spaces on the inner side of the supporting aluminum profile 2. Through the stability of the triangle, the impact resistance of the supporting aluminum profile 2 is improved. Furthermore, the inner side of the reinforcing rib plate 23 is fixed with a reinforcing strip 24, which facilitates further strengthening of the device's robustness. In the event of damage caused by a particularly large impact, the supporting aluminum profile 2, the first connecting block 3, and the second connecting block 4 can be replaced individually, making maintenance convenient.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
