[0023] The specific implementation methods of the present utility model will be further explained in detail below by describing the optimal embodiments with reference to the accompanying drawings.

[0024] An A-pillar reinforcement assembly includes a reinforcement assembly 1, wherein the reinforcement assembly 1 includes an A-pillar reinforcement plate 2 and a side panel front connecting plate 3; the A-pillar reinforcement plate 2 and the side panel front connecting plate 3 are designed to be integrated; the utility model integrates the A-pillar reinforcement plate 2 and the side panel front connecting plate 3 into one body, and forms them in one step through a high-pressure die-casting process, and does not require further welding or other connections, so the production process is greatly simplified, and the material used is aluminum alloy, which can reduce the weight by 25%-35%; such a design can meet the requirements of lightweighting the automobile body, shortening the manufacturing process, reducing the number of parts, improving the assembly accuracy, and improving the integration of the entire vehicle.

[0025] Specifically, the A-pillar reinforcement assembly disclosed in the utility model is essentially an integration of the traditional A-pillar reinforcement plate assembly + the side panel front connecting plate assembly structure; the welding process during the assembly of the traditional A-pillar reinforcement plate assembly + the side panel front connecting plate assembly structure is simplified.

[0026] In the present invention, the A-pillar reinforcement assembly mainly includes a reinforcement assembly 1, which is the main structure of the A-pillar reinforcement assembly. In the present invention, the reinforcement assembly 1 includes an A-pillar reinforcement plate 2 and a side panel front connecting plate 3. The A-pillar reinforcement plate 2 and the side panel front connecting plate 3 are designed in an integrated manner, so that the A-pillar reinforcement plate 2 and the side panel front connecting plate 3 form an integral structure, thereby ensuring the integrity of the A-pillar reinforcement assembly.

[0027] Furthermore, the reinforcement assembly 1 described in the utility model is made of alloy aluminum material; the alloy elements in the reinforcement assembly 1 in the utility model can be one or a combination of magnesium, copper, silicon, and manganese, and the alloy content can be between 3% and 15%. If multiple elements are alloyed, the total content generally does not exceed 15%; the specific selection can be based on needs.

[0028] Furthermore, in the present invention, the reinforcement assembly 1 is formed by a die-casting process; in the present invention, such a production method is adopted, which not only facilitates the production of the reinforcement assembly 1, but also greatly ensures the manufacturing efficiency and progress of the reinforcement assembly 1.

[0029] Furthermore, in the present invention, the reinforcement assembly 1 includes a base plate 4, and a reinforcement side edge 5 is provided at the edge of the base plate 4; the base plate 4 is the main structure of the reinforcement assembly 1, and the provision of the reinforcement side edge 5 can well ensure the overall structural strength of the reinforcement assembly 1.

[0030] Furthermore, in the utility model, a weakening and reducing hole 6 is provided at one end of the side enclosure front connecting plate 3 close to the A-pillar reinforcement plate 2; the setting of the weakening and reducing hole 6 can reduce the excessive displacement of the A-pillar body caused by the collision force, which affects the opening and closing of the vehicle door; because the A-pillar reinforcement assembly 1 serves as a force transmission member for frontal collision, and it is also necessary to prevent the collision from affecting the opening and closing of the vehicle door, so by designing the weakening and reducing hole 6, it is equivalent to appropriately weakening the structure at the front of the A-pillar reinforcement assembly, thereby achieving the above-mentioned technical effect.

[0031] Furthermore, in the present invention, the reinforced side edge 5 at the connection between the side panel front connecting plate 3 and the A-pillar reinforcement plate 2 adopts an arc-shaped design; such a setting ensures the smoothness of the transition at the connection between the side panel front connecting plate 3 and the A-pillar reinforcement plate 2.

[0032] A vehicle body frame assembly comprises an A-pillar inner panel assembly, a front windshield lower crossbeam assembly, a side panel outer panel and the A-pillar reinforcement assembly; the A-pillar reinforcement assembly is respectively connected to the A-pillar inner panel assembly, the front windshield lower crossbeam assembly and the side panel outer panel by welding.

[0033] specific:

[0034] The utility model discloses an A-pillar reinforcement assembly and a vehicle body frame assembly having the A-pillar reinforcement assembly; the utility model provides a new material, process and structure applied to the A-pillar reinforcement assembly structure of an automobile, aiming to meet the requirements of the automobile body in terms of lightweight, shortening the manufacturing process, reducing the number of parts, improving assembly accuracy, and improving integration.

[0035] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: integrating the traditional A-pillar reinforcement plate 2 assembly and the side panel front connecting plate 3 assembly structure into one body through a die-casting process.

[0036] The material used in manufacturing the A-pillar reinforcement assembly disclosed in the utility model is an alloy aluminum, and the alloy element can be one or a combination of several of magnesium, copper, silicon, and manganese. The alloy content can be between 3% and 15%. If multiple elements are alloyed, the total content generally does not exceed 15%.

[0037] According to the structural form of the A-pillar reinforcement assembly, a high-pressure casting process is adopted to realize it. The technical characteristics of high-pressure casting are that it can form relatively complex structures and thin-walled structures, and the minimum thickness can reach 1mm to 1.5mm. The integrated structure of the A-pillar reinforcement assembly of the utility model integrates the plate structure and the beam structure. The beam structure needs to be criss-crossed and the plate structure needs to be relatively thin. Therefore, it is very suitable to be realized by the high-pressure casting process method.

[0038] The A-pillar reinforcement assembly of the utility model is an integral part, covering all the functions of this area of ​​the traditional sheet metal structure. The A-pillar reinforcement assembly serves as a force transmission part for frontal collision, and at the same time, it is also necessary to prevent the collision from affecting the opening and closing of the vehicle door. The structure can be appropriately weakened at the front of the A-pillar reinforcement assembly to reduce the excessive displacement of the main body of the A-pillar reinforcement assembly caused by the collision force, which affects the opening and closing of the vehicle door.

[0039] The A-pillar reinforcement assembly can be connected to the side panel upper beam reinforcement plate, the A-pillar inner panel assembly, the front windshield lower cross beam assembly, the side panel outer panel, etc. through SPR, laser welding, etc., and can be connected to the door sill beam reinforcement plate through SPR, FDS, laser welding, MIG welding or bolts to finally form a complete body frame structure.

[0040] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
