Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a lightweight A-pillar reinforcement for automobiles. Background Technology

[0002] A-pillar reinforcement components are reinforcing parts located inside or outside the A-pillar (the pillars connecting the roof and the front compartment on both sides of the windshield) of a vehicle. They are mainly used to improve the structural strength, impact resistance, and connection reliability of the A-pillar.

[0003] In the existing technology, automotive A-pillar reinforcement components have complex internal structures, which increases weight and leads to increased fuel consumption, offsetting the safety gains. At the same time, during A-pillar maintenance, cutting and re-welding may cause stress concentration, resulting in strength reduction. Therefore, in order to reduce the weight of the reinforcement component and avoid strength reduction during maintenance, a lightweight automotive A-pillar reinforcement component is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight automotive A-pillar reinforcement component to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A lightweight automotive A-pillar reinforcement includes an outer steel body, a main reinforcement assembly installed inside the outer steel body, an energy-absorbing component installed inside the main reinforcement assembly, and sound-absorbing cotton installed on the side of the outer steel body away from the surface of the main reinforcement assembly. The outer steel body includes a mounting fastener and a flow-guiding insert, the mounting fastener being located on the surface of the outer steel body and the flow-guiding insert being located on the inner wall of the outer steel body. The main reinforcement assembly includes a reinforcement member and a mounting member, the reinforcement member being located inside the outer steel body and the mounting member being located inside the reinforcement member.

[0007] A further improvement of this utility model's technical solution lies in the following: the mounting fastener includes a single-sided shell, which is located on the side away from the sound insulation cotton. A reamed bolt is fixedly installed on the surface of the single-sided shell, and the end of the reamed bolt penetrates the inner wall of the single-sided shell and slides against the inner wall of the single-sided shell. An angle steel bolt is fixedly installed on the surface of the single-sided shell. The mounting fastener allows the single-sided shell and the three-sided shell to be combined with each other. Compared with the welding method, this method of fixing with reamed bolts and angle steel bolts is detachable and avoids cutting the A-pillar during maintenance, which would cause stress concentration in the A-pillar.

[0008] A further improvement of this utility model is that the flow guide embedding includes a three-dimensional housing, the inner wall of which is fixed to the outer surface of the sound insulation cotton, a flow guide groove is formed on the surface of the three-dimensional housing, an embedding sleeve is fixedly installed on the inner wall of the three-dimensional housing, the surface of the three-dimensional housing contacts the end of the reamed hole bolt, and the surface of the three-dimensional housing contacts the surface of the angle steel bolt. The flow guide groove provided by the flow guide embedding can reduce wind noise and wind resistance, while the embedding sleeve can cooperate with the mounting block to achieve the effect of relieving part of the external pressure.

[0009] A further improvement of this utility model is that the reinforcing member includes a reinforcing core plate, which is fixedly installed on the inner wall of the outer steel body. Several reinforcing blocks are fixedly installed on the surface of the reinforcing core plate, and reinforcing ribs are fixedly installed on the surface of the reinforcing core plate. The two ends of the reinforcing ribs are fixed to the surface of the reinforcing blocks. The reinforcing member can make the internal structure of the car A-pillar more stable, reduce the deformation caused by the collision, and protect the safety of the front compartment.

[0010] A further improvement of this utility model is that the mounting component includes a mounting block, which is fixedly installed inside the reinforcing rib and fixed to the surface of the reinforcing core plate. The surface of the reinforcing rib is provided with a mounting groove, and the inner wall of the mounting groove is adapted to the surface of the embedded sleeve. Through the mutual cooperation between the mounting component and the embedded sleeve, the effect of relieving part of the external pressure can be achieved.

[0011] A further improvement of this utility model is that the energy-absorbing component includes a central column, which is fixedly installed on the inner wall of the reinforcing core plate. Several energy-absorbing blocks are provided on the surface of the reinforcing core plate, and steel bars are fixedly installed on the inner wall of the central column. The energy-absorbing component is used to offset local shock waves, ensuring that the front compartment survival space does not deform. At the same time, the low density of the energy-absorbing component material can reduce the overall weight of the A-pillar, thereby reducing the weight of the entire vehicle body and achieving the effect of reducing fuel consumption.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a lightweight A-pillar reinforcement for automobiles. By installing fasteners and guide inserts, the entire structure can be fixedly connected together, avoiding the stress concentration and strength reduction that may occur when cutting and re-welding during maintenance after welding, thus reducing the overall safety protection effect of the A-pillar. At the same time, the guide groove can reduce wind noise and wind resistance for automobiles.

[0014] 2. This utility model provides a lightweight A-pillar reinforcement for automobiles. Through the cooperation of the reinforcement and sound insulation cotton, the overall rigidity and hardness requirements of the A-pillar can be guaranteed, avoiding local deformation caused by impact. At the same time, it can also reduce the noise of rainwater dripping on the A-pillar from entering the car interior, providing overall interior comfort.

[0015] 3. This utility model provides a lightweight A-pillar reinforcement for automobiles. Through the cooperation of the energy-absorbing component and the reinforcement component, the overall rigidity of the A-pillar can be guaranteed during an impact, while the local shock wave can be offset to ensure that the front compartment survival space does not deform. At the same time, the low density of the energy-absorbing component material can reduce the overall weight of the A-pillar, thereby reducing the weight of the entire vehicle body and achieving the effect of reducing fuel consumption.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1, such as Figures 1 to 7 As shown, this utility model provides a lightweight design for a car A-pillar reinforcement, including an outer steel body 1, a main reinforcement component 2 installed inside the outer steel body 1, an energy-absorbing component 3 installed inside the main reinforcement component 2, and sound insulation cotton 4 installed on the side of the outer steel body 1 away from the surface of the main reinforcement component 2. The outer steel body 1 includes a mounting fastener and a flow guide insert. The mounting fastener is located on the surface of the outer steel body 1, and the flow guide insert is located on the inner wall of the outer steel body 1. The main reinforcement component 2 includes a reinforcement component and a mounting component. The reinforcement component is located inside the outer steel body 1, and the mounting component is located inside the reinforcement component. Through the cooperation of the main reinforcement component 2 and the energy-absorbing component 3, the overall rigidity of the car A-pillar can be maintained during an impact, while offsetting local shock waves to ensure that the front compartment survival space does not deform. At the same time, the low density of the energy-absorbing component material can reduce the overall weight of the A-pillar, thereby reducing the weight of the entire car body and achieving the effect of reducing fuel consumption.

[0027] Example 2, as Figures 1 to 7As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the mounting fastener includes a single-sided housing 14, located on the side away from the sound insulation cotton 4. A reamer bolt 15 is fixedly mounted on the surface of the single-sided housing 14, the end of which penetrates the inner wall of the single-sided housing 14 and slides against the inner wall of the single-sided housing 14. An angle steel bolt 16 is fixedly mounted on the surface of the single-sided housing 14. The flow guide embedding component includes a three-sided housing 11, the inner wall of which is fixed to the outer surface of the sound insulation cotton 4. A flow guide groove 12 is opened on the surface of the body 11, and an embedded sleeve 13 is fixedly installed on the inner wall of the three-dimensional shell 11. The surface of the three-dimensional shell 11 is in contact with the end of the reamed hole bolt 15 and the surface of the three-dimensional shell 11 is in contact with the surface of the angle steel bolt 16. By installing the fastener and the flow guide embedded part, the whole can be fixedly connected together, avoiding the stress concentration that may be caused by cutting and re-welding during maintenance after welding, which would lead to strength reduction and reduce the overall safety protection effect of the A-pillar. At the same time, the flow guide groove 12 can reduce wind noise and wind resistance of the car.

[0028] Example 3, as Figures 1 to 7 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, the reinforcing member includes a reinforcing core plate 21, which is fixedly installed on the inner wall of the outer steel body 1. Several reinforcing blocks 22 are fixedly installed on the surface of the reinforcing core plate 21, and reinforcing ribs 25 are fixedly installed on the surface of the reinforcing core plate 21. The two ends of the reinforcing ribs 25 are fixed to the surface of the reinforcing blocks 22. The mounting member includes a mounting block 23, which is fixedly installed inside the reinforcing ribs 25 and fixed to the surface of the reinforcing core plate 21. The surface of the reinforcing ribs 25 is provided with a mounting groove 24, and the inner wall of the mounting groove 24 is adapted to the surface of the embedded sleeve 13. By the cooperation of the reinforcing member and the mounting member, the effect of relieving part of the external pressure can be achieved.

[0029] Example 4, as Figures 1 to 7 As shown, based on embodiments 1-3, this utility model provides a technical solution: Preferably, the energy-absorbing component 3 includes a central column 31, which is fixedly installed on the inner wall of the reinforcing core plate 21. The surface of the reinforcing core plate 21 is provided with a plurality of energy-absorbing blocks 33. The inner wall of the central column 31 is fixedly installed with reinforcing bars 32. The side of the outer steel body 1 away from the surface of the main reinforcing component 2 is equipped with sound insulation cotton 4. Through the cooperation of the energy-absorbing component 3 and the sound insulation cotton 4, local shock waves can be offset to ensure that the front compartment survival space does not deform. At the same time, the low density of the energy-absorbing component material can reduce the overall weight of the A-pillar, thereby reducing the weight of the entire vehicle body and achieving the effect of reducing fuel consumption. It can also reduce the noise of rainwater dripping on the A-pillar from entering the car interior, providing overall interior comfort.

[0030] The following is a detailed description of the working principle of this lightweight automotive A-pillar reinforcement component.

[0031] During installation, the three-dimensional shell 11 and the single-sided shell 14 of the outer steel body 1 will be fitted together to achieve an overall fixed connection. The reamed bolts 15 and angle iron bolts 16 inside the single-sided shell 14 play a leading role in the overall fixation. After the outer steel body 1 is installed, the guide channel 12 inside the outer steel body 1 reduces wind resistance and wind noise. The embedded sleeve 13 inside the outer steel body 1 will cooperate with the mounting groove 24 and mounting block 23 inside the main body reinforcing component 2 to achieve a force-dissipating effect during impact. Several reinforcing blocks 22 set on the main body reinforcing component 2 can improve the overall hardness, while the reinforcing ribs 25 will ensure the hardness requirements between adjacent reinforcing core plates 21. The energy-absorbing component 3 installed inside the main reinforcement component 2 can offset local shock waves and ensure that the front compartment survival space does not deform. The steel bar 32 installed on the central pillar 31 is the last layer of safety protection for the entire A-pillar of the car, which plays a crucial role in protecting the safety of the front compartment. The energy-absorbing block 33 is composed of the main board 331, the rubber support column 332 and the base plate 333. When the main board 331 is pressed down, the rubber support column 332 will be pressed down in the cavity of the main board 331 and the base plate 333, thus achieving the energy absorption function. Finally, sound insulation cotton 4 is installed between the external steel body 1 and the energy-absorbing component 3 to reduce the noise transmitted from the outside. The overall installation is completed.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
