Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile manufacturing, and in particular to an aluminum alloy A-pillar structure with high strength and waterproof function. Background Art
[0002] Publication number CN213676905U discloses a hybrid material hydrogen-energy automobile A-pillar structure, comprising a side panel outer panel, a side panel inner panel, a first aluminum alloy profile, and a second aluminum alloy profile. The side panel outer panel and the side panel inner panel are buckled together to form a cavity. The first aluminum alloy profile is provided with a plurality of reinforcing ribs inside, and the second aluminum alloy profile is provided with a cross-shaped reinforcing rib inside. The upper side edge of the second aluminum alloy profile abuts against the first aluminum alloy profile, and the lower side edge of the second aluminum alloy profile is bonded to the inner side of the side panel outer panel by an adhesive. The right side edge of the second aluminum alloy profile is bonded to the inner side of the side panel inner panel by an adhesive. Beneficial effects of the utility model: The utility model utilizes the high designability of carbon fiber composite materials and the process characteristics of aluminum alloy material molding to effectively reduce the investment in processing molds and tooling; and while ensuring the safety of the vehicle body, by adopting a combination of carbon fiber composite materials and aluminum alloy materials, the weight of the automobile A-pillar is effectively reduced, thereby achieving the purpose of lightweighting. Aluminum alloy vehicle body structures have attracted widespread attention due to their advantages such as lightweight, environmental friendliness, and recyclability. While aluminum alloy extruded profiles offer a wide range of cross-sectional designs due to their molding process, traditional hollow sections create a connection between the interior and exterior of the vehicle after installation. If the waterproof clips fail, rainwater can flow into the cab through the holes in the A-pillar. The aforementioned patent lacks a waterproofing feature and cannot address the issue of rainwater leakage. Therefore, a high-strength and waterproof aluminum alloy A-pillar structure is proposed.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, more specifically, a high-strength and waterproof aluminum alloy A-pillar structure includes an aluminum profile, and the aluminum profile has profile reinforcement ribs integrally formed inside. Under the separation of the profile reinforcement ribs, the interior of the aluminum profile is set as a first cavity and a second cavity from left to right in sequence, thereby achieving mutual sealing and isolation of the two cavities.
[0005] Furthermore, the aluminum profile is adhered to a front windshield above the first cavity, and an A-pillar interior panel is clipped to the lower surface of the aluminum profile below the first cavity through a buckle;
[0006] The outer surface of the aluminum profile is located above the upper portion and is provided with a front door upper stop. Rivets are provided on the outer surface of the aluminum profile and the inside of the front door upper stop. The aluminum profile and the front door upper stop are riveted together by the rivets. The left A-pillar outer guard body is clamped to the inner side of the front door upper stop by a buckle.
[0007] Furthermore, the bottom end of the aluminum profile is welded to the outer upper plate of the left front side panel of the external vehicle, and a plurality of drainage holes are provided on the outer surface of the outer upper plate of the left front side panel.
[0008] Furthermore, the aluminum profile is rolled into a required curvature according to the different exterior shapes of the vehicle body to adapt to different vehicles.

[0010] The technical solution adopted by this utility model is a high-strength and waterproof A-pillar profile section; it is an aluminum alloy one-piece molded structure, and the profile is divided into two left and right hollow cavities. The first cavity includes an interior mounting surface and a glass adhesive surface, and the second cavity includes a sheet metal riveting surface, etc. The above two cavities are separated by a reinforcing rib in the middle, so that the left and right cavities are not connected. Rainwater leaking from the outer rivet holes and positioning holes in the second cavity can be discharged along the second cavity of the A-pillar. While increasing the cross-sectional strength, it achieves a waterproof function, improves production efficiency, reduces production costs, is simple to assemble, and has a beautiful appearance.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
[0016] like Figure 1-2As shown, according to one aspect of the present invention, a high-strength and waterproof aluminum alloy A-pillar structure is provided, including an aluminum profile 9, and a profile reinforcement rib 3 is integrally formed inside the aluminum profile 9. The interior of the aluminum profile 9 is divided by the profile reinforcement rib 3 and is sequentially provided with a first cavity 1 and a second cavity 2 from left to right, thereby achieving mutual sealing and isolation of the two cavities.
[0017] In this embodiment, the aluminum profile 9 is located above the first cavity 1 and is adhered to the front windshield 4. The outer surface of the aluminum profile 9 is located below the first cavity 1 and is fastened to the A-pillar interior panel 5 through a buckle.
[0018] The outer surface of the aluminum profile 9 is located above 2 and is provided with a front door upper stop 7. The outer surface of the aluminum profile 9 and the inside of the front door upper stop 7 are both provided with rivets 8. The aluminum profile 9 and the front door upper stop 7 are riveted together by rivets 8. The inner side of the front door upper stop 7 is clipped with the left A-pillar outer protective surface body 6 by a buckle.
[0019] In this embodiment, the bottom end of the aluminum profile 9 is welded to the outer upper plate of the left front side panel of the external vehicle, and a plurality of drainage holes are provided on the outer surface of the left front side panel; rainwater leaking from the rivet holes and positioning holes on the outside of the vehicle can flow along the second cavity of the A-pillar to the outer upper plate of the left front side panel, and then flow out from the reserved drainage holes, thereby realizing the drainage function.
[0020] In this embodiment, the aluminum profile 9 is rolled into a required curvature according to different vehicle body exterior shapes to adapt to different vehicles.
[0021] The working principle of this utility model is as follows: the interior of the aluminum profile 9 is divided into two hollow cavities, the first cavity 1, which includes the interior trim mounting surface and the glass adhesive surface, and the second cavity 2, which includes the sheet metal riveting surface. These two cavities are separated by a central reinforcing rib, ensuring that the left and right cavities are not connected. Rainwater leaking from the outer rivet holes and positioning holes in the second cavity 2 can be drained through the A-pillar second cavity 2. This increases the cross-sectional strength while achieving waterproofing.
[0022] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the scope of protection of the present invention.
