Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile parts, especially relates to a super thin special-shaped aluminium alloy extrusion section for automobile. BACKGROUND
[0002] In the field of automobile manufacturing, the aluminium alloy extrusion section for automobile as a key component, its performance is closely related to the safety performance and overall quality of the automobile. This type of section is mainly used for connecting the automobile anti-collision beam and the frame, and bears the responsibility of buffering and dispersing impact force when the automobile collides, which is an important defense line to protect the life safety of the driver and passenger.
[0003] At present, the existing aluminium alloy extrusion section for automobile has a relatively simple structure, and is mostly provided with a common integral metal frame and is fixed between the automobile anti-collision beam and the frame by a simple connecting mode, and mainly relies on the rigidity of the overall frame to resist the impact force.
[0004] However, the existing aluminium alloy extrusion section for automobile has the following limitations in actual use:
[0005] Firstly, the existing structure lacks effective multistage buffering design, and when the automobile anti-collision beam is subjected to impact force, the impact force cannot be buffered for multiple times in sequence, the buffering effect of the impact force is poor, and the safety of the driver cannot be fully guaranteed. Secondly, the existing section structure is not reasonable in deformation design, and reasonable positions and directions are not provided for deformation, and when the impact force is faced, the overall structure is easily damaged due to unreasonable deformation, and even the impact force cannot be effectively buffered. In addition, the existing structure is of an integral design, and when damaged, the overall structure needs to be replaced, and the use cost is high.
[0006] Therefore, it is very necessary to invent a super thin special-shaped aluminium alloy extrusion section for automobile. CONTENT OF THE UTILITY MODEL
[0007] The utility model aims at providing a super thin special-shaped aluminium alloy extrusion section for automobile, which solves the problems mentioned in the background.
[0008] To solve the above technical problems, the utility model is realized by the following technical scheme:
[0009] The utility model is a super thin special-shaped aluminium alloy extrusion section for automobile, which comprises a first assembly frame, a second assembly frame, a first mounting plate and a second mounting plate, one end of the first assembly frame is integrally formed with the second mounting plate, a second mounting plate is integrally formed with the second mounting plate, and the second mounting plate is fixed on the automobile anti-collision beam through bolts; the end of the first assembly frame away from the second mounting plate is fixed with the second assembly frame through bolts, and the other end of the second assembly frame is integrally formed with the first mounting plate, and the first mounting plate is fixed on the automobile frame through bolts.
[0010] Furthermore, the first assembly frame includes a corrugated pipe, a third mounting plate, and a positioning tube. One end of the corrugated pipe is integrally formed with a second mounting plate, and the other end of the corrugated pipe is integrally formed with a third mounting plate. The third mounting plate is fixed to the second assembly frame by bolts. The side of the third mounting plate away from the corrugated pipe is integrally formed with a positioning tube, which is slidably disposed inside the second assembly frame. This arrangement can provide initial buffering of the impact force received by the vehicle anti-collision beam.
[0011] Furthermore, the corrugation curvature of the corrugated pipe near the second mounting plate is greater than that far from the second mounting plate. This arrangement can prevent the deformation of the corrugated pipe from affecting the second assembly frame when the impact force is small.
[0012] Furthermore, the second assembly frame includes an inner tube, reinforcing ribs, an outer tube, and a fourth mounting plate. The fourth mounting plate is integrally formed at one end of the inner tube, and the fourth mounting plate is fixed to the first assembly frame by bolts. Several reinforcing ribs are integrally formed uniformly on the outer side of the inner tube, and the other ends of the reinforcing ribs are fixed to the inner wall of the outer tube. The first mounting plate is integrally formed at the end of the outer tube away from the fourth mounting plate. This arrangement can provide a second and third buffer against the impact force suffered by the car anti-collision beam.
[0013] Furthermore, the second assembly frame also includes through holes, which are evenly distributed on the inner and outer tubes. This arrangement allows the through holes to provide deformation positions for deformation.
[0014] Furthermore, the first assembly frame and the second mounting plate are made of extruded aluminum alloy material; the second assembly frame and the first mounting plate are made of extruded aluminum alloy material.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The design of the first assembly frame of this utility model ensures that when the car anti-collision beam is subjected to impact force, the corrugated pipe will deform first, thereby providing initial buffering of the impact force. Since the corrugation curvature of the corrugated pipe near the second mounting plate is greater than that away from the second mounting plate, when the impact force is small, the corrugated pipe near the second mounting plate deforms first, avoiding the deformation of the corrugated pipe directly affecting the second assembly frame when the impact force is small. Moreover, when the impact force on the car anti-collision beam is small, if the first assembly frame can completely buffer the impact force, only the first assembly frame needs to be replaced in the future.
[0017] 2. The second assembly frame of this utility model can buffer the impact force on the car anti-collision beam when the first assembly frame cannot completely buffer the impact force. The inner tube will buffer the impact force a second time, and the reinforcing rib and outer tube can further buffer the impact force a third time, thereby ensuring the safety of the driver. In addition, the through holes evenly distributed on the inner tube and outer tube can provide a position for the deformation of the inner tube and outer tube, making the deformation more reasonable.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] Please see Figs. 1-4 As shown, this utility model is an ultra-thin irregular-shaped aluminum alloy extruded profile for automobiles, including a first assembly frame 1, a second assembly frame 2, a first mounting plate 3, and a second mounting plate 4. One end of the first assembly frame 1 is integrally formed with the second mounting plate 4, and an automobile anti-collision beam is fixed to the second mounting plate 4 by bolts. The end of the first assembly frame 1 away from the second mounting plate 4 is fixed to the second assembly frame 2 by bolts, and the other end of the second assembly frame 2 is integrally formed with the first mounting plate 3, which is fixed to the automobile frame by bolts.
[0028] Specifically, the first assembly frame 1 includes a corrugated pipe 11, a third mounting plate 12, and a positioning tube 13. One end of the corrugated pipe 11 is integrally formed with a second mounting plate 4, and the other end of the corrugated pipe 11 is integrally formed with a third mounting plate 12. The third mounting plate 12 is fixed to the second assembly frame 2 by bolts. The side of the third mounting plate 12 away from the corrugated pipe 11 is integrally formed with a positioning tube 13. The positioning tube 13 is slidably disposed inside the second assembly frame 2. When the car anti-collision beam is subjected to an impact force, the corrugated pipe 11 will deform first, thereby buffering the impact force suffered by the car anti-collision beam. The positioning tube 13 can improve the connection between the first assembly frame 1 and the second assembly frame 2.
[0029] Specifically, the corrugation curvature of the corrugated pipe 11 near the second mounting plate 4 is greater than that of the corrugated pipe far from the second mounting plate 4. During use, when the car anti-collision beam is subjected to an impact force, the part near the second mounting plate 4 will deform first, and then the corrugated pipe 11 far from the second mounting plate 4 will deform accordingly with the impact force. This setting can prevent the deformation of the corrugated pipe 11 from affecting the second assembly frame 2 when the impact force is small.
[0030] Specifically, the second assembly frame 2 includes an inner tube 21, reinforcing ribs 22, an outer tube 23, and a fourth mounting plate 25. The fourth mounting plate 25 is integrally formed at one end of the inner tube 21, and the fourth mounting plate 25 is fixed to the first assembly frame 1 by bolts. Several reinforcing ribs 22 are integrally formed uniformly on the outer side of the inner tube 21, and the other end of each reinforcing rib 22 is fixed to the inner wall of the outer tube 23. The first mounting plate 3 is integrally formed at the end of the outer tube 23 away from the fourth mounting plate 25. In use, when the first assembly frame 1 is subjected to excessive impact force due to the car anti-collision beam, the impact force will act on the inner tube 21, thereby causing the inner tube 21 to deform accordingly, thus providing a second buffer against the impact force. The reinforcing ribs 22 and the outer tube 23 can limit the deformation of the inner tube 21. When the deformation of the inner tube 21 is large, the reinforcing ribs 22 and the outer tube 23 can deform accordingly, thus providing a third buffer against the impact force.
[0031] Specifically, the second assembly frame 2 also includes through holes 24, which are evenly distributed on the inner tube 21 and the outer tube 23. With this arrangement, when the inner tube 21 and the outer tube 23 are deformed, the through holes 24 can provide a deformation position for the deformation.
[0032] Specifically, the first assembly frame 1 and the second mounting plate 4 are made of extruded aluminum alloy material; the second assembly frame 2 and the first mounting plate 3 are made of extruded aluminum alloy material.
[0033] Please see Figs. 1-4 As shown, this utility model is an ultra-thin irregular-shaped aluminum alloy extruded profile for automobiles. Its working principle is as follows: When in use, the profile can be fixed to the car frame by the cooperation of bolts and the first mounting plate 3, and the car anti-collision frame can be fixed to the profile by the cooperation of bolts and the second mounting plate 4. When the car anti-collision frame is subjected to impact force, the first mounting frame 1 can initially buffer the impact force, and then the second mounting frame 2 can buffer the remaining impact force.
