Description

Technical Field

[0001] This utility model belongs to the field of automobile A-pillars, specifically, this utility model relates to an automobile A-pillar structure. Background Technology

[0002] As automotive safety crash test requirements become increasingly stringent, the standards for the A-pillar structure of the vehicle frame are also rising. Firstly, the A-pillar must provide sufficient strength to prevent deformation of the passenger compartment. Secondly, the A-pillar must minimize its impact on the driver's visibility. Thirdly, the A-pillar must provide installation space for wiring harnesses, interior trim panels, sunroof drain pipes, curtain airbags, and other assembly components. Current automotive A-pillars typically consist of an outer side panel, a reinforcing A-pillar plate, and an inner reinforcing A-pillar plate. To meet crash strength requirements, the A-pillar cross-sectional area is often designed to be very large, which can obstruct the driver's view.

[0003] To address the aforementioned issues, patent document publication number 217048785U discloses a lower A-pillar for automobiles, an A-pillar for automobiles, and an automobile. The lower A-pillar includes an inner lower A-pillar panel, an outer lower A-pillar panel, a first hinge reinforcement plate, and a second hinge reinforcement plate. The main deformation area of ​​the outer lower A-pillar panel and the inner lower A-pillar panel is located between the first and second hinge reinforcement plates. The lower A-pillar also includes a first support member and a second support member, which are disposed on the main deformation area of ​​the outer lower A-pillar panel, but this does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a car A-pillar structure is provided that is conducive to improving the structural strength of the car A-pillar, meeting the collision strength requirements, improving the compactness of the car A-pillar structure, and reducing the impact on the driver's vision.

To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0021] Figure 1 This is a schematic diagram of the structure of the A-pillar of a car in an embodiment of this utility model; Figure 2 This is a cross-sectional view of the car A-pillar structure in the front view direction in an embodiment of this utility model; Figure 3 This is a cross-sectional view of the A-pillar structure of a car in an embodiment of this utility model.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, the A-pillar structure of the automobile provided by this utility model includes an outer side panel 10 and an inner A-pillar panel 20 connected to the outer side panel 10. A reinforcing component 30 is provided between the outer side panel 10 and the inner A-pillar panel 20. The reinforcing component 30 can improve the structural strength and load-bearing capacity of the automobile A-pillar structure, enabling the automobile A-pillar to meet the collision strength requirements. It is also beneficial to improve the compactness of the automobile A-pillar structure, reduce the cross-sectional area of ​​the automobile A-pillar structure, and reduce the impact on the driver's vision. Therefore, the automobile A-pillar structure provided by this utility model has the characteristics of high structural strength and high load-bearing capacity, meets the collision strength requirements, improves structural compactness, reduces the cross-sectional area of ​​the automobile A-pillar structure, and reduces the impact on the driver's vision.

[0023] A pre-set cavity 40 is formed between the outer side panel 10 and the inner A-pillar panel 20. The reinforcing component 30 is located in the pre-set cavity 40. At the same time, the pre-set cavity 40 can also provide installation space for assembly components such as wiring harnesses, interior panels, sunroof drain pipes, and air curtains, which helps to improve the compactness of the structure.

[0024] The reinforcement component 30 includes an A-pillar reinforcement plate 31, which is connected to the outer side panel 10 and the inner A-pillar panel 20. The A-pillar reinforcement plate 31 is located in a preset cavity 40. The A-pillar reinforcement plate 31 can effectively disperse collision energy and reduce the degree of deformation of the A-pillar of the car, thereby protecting the safety of passengers inside the car. In a frontal collision, the reinforcement plate can transfer the collision force to other parts of the car body, preventing the A-pillar of the car from directly bearing excessive impact force and breaking or severely deforming.

[0025] The reinforcing component 30 also includes a conformal reinforcing tube 32, which is connected to the A-pillar reinforcing plate 31 and located within a pre-set cavity 40. The conformal reinforcing tube 32 and the A-pillar reinforcing plate 31 are connected by arc welding. The conformal reinforcing tube 32 bends to follow the shape of the A-pillar reinforcing plate 31, better adapting to the A-pillar reinforcing plate 31 and the structure of the car's A-pillar. One end of the conformal reinforcing tube 32 is located at the connection between the car's A-pillar and the front end of the car body, and the other end of the conformal reinforcing tube 32 is located at the connection between the car's A-pillar and the car's B-pillar.

[0026] The conformal reinforcing tube 32 extends through the upper and lower inflection points or overlapping points of the A-pillar, ensuring the strength of these points and enhancing the A-pillar's resistance to collisions and rollovers. This ensures the integrity of the passenger compartment and improves the vehicle's safety level. Simultaneously, under the same collision performance requirements, it allows for a reduction in the cross-sectional design of the A-pillar, thereby minimizing its impact on the driver's visibility. Improved visibility enhances driving safety.

[0027] The conformal reinforcing tube 32 can also be used as a sunroof drain pipe, eliminating the rubber drain pipe that is usually installed on the inner panel 20 of the A-pillar on ordinary models. This reduces the total number of components on the inner panel 20 of the A-pillar, which helps to further reduce the cross-sectional area of ​​the A-pillar structure and reduce the impact on the driver's vision.

[0028] The conformal reinforcing tube 32 is made of seamless steel pipe with a material grade greater than 45 steel. The diameter of the conformal reinforcing tube 32 is greater than or equal to 25mm, and the wall thickness is greater than or equal to 1.8mm. This is beneficial to improving the structural strength and load-bearing capacity of the car A-pillar structure, enabling the car A-pillar to meet the collision strength requirements.

[0029] The role and effect of the embodiments

[0030] The A-pillar structure provided by this utility model includes an outer side panel 10 and an inner A-pillar panel 20 connected to the outer side panel 10. A reinforcing component 30 is provided between the outer side panel 10 and the inner A-pillar panel 20. The reinforcing component 30 can improve the structural strength and load-bearing capacity of the A-pillar structure, enabling the A-pillar to meet the collision strength requirements. It is also beneficial to improve the compactness of the A-pillar structure, reduce the cross-sectional area of ​​the A-pillar structure, and reduce the impact on the driver's vision. Therefore, the A-pillar structure provided by this utility model has the characteristics of high structural strength and high load-bearing capacity, meets the collision strength requirements, improves structural compactness, reduces the cross-sectional area of ​​the A-pillar structure, and reduces the impact on the driver's vision.
