[0014] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example
[0015] As shown in Figure 1- Figure 4As shown, a reinforced and anti-deformation automotive A-pillar assembly structure includes an outer panel 1, a reinforcing structure 2 fixedly welded to the inner side of the outer panel 1, and a connecting base 3 fixedly welded to the bottom end of both the outer panel 1 and the reinforcing structure 2. The reinforcing structure 2 includes a first reinforcing support plate 21 and a second reinforcing support plate 22. The surfaces of the first reinforcing support plate 21 and the second reinforcing support plate 22 are provided with fixing slots 23. A first reinforcing plate 24, a second reinforcing plate 26, and a third reinforcing plate 28 are movably inserted into the inner side of the fixing slots 23. A fixing groove 210 is provided at one end of each of the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28.
[0016] The working principle of the above technical solution is as follows: During use, the outer plate 1, reinforcing structure 2, and connecting base 3 effectively disperse the force of external impacts, thus protecting the entire structure and preventing deformation damage. The overall structure is simple and easy to operate. The first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 are inserted into the inner side of the fixing slot 23 in sequence. Welding is then performed when the first reinforcing plate 24 is inserted into the fixing slot 23. Welding is then performed between the first reinforcing support plate 21, the second reinforcing support plate 22, the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 in sequence. Finally, the first reinforcing support plate 21 and the second reinforcing support plate 22 are welded to the outer plate 1, and the ends of the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 are welded and fixed to the outer plate 1.
[0017] In another embodiment, such as Figure 4 As shown, the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 are welded and fixed to the second reinforcing support plate 22 and the fixing slot 23. This facilitates the improvement of the connection strength and stability between the components, enabling the entire assembly to be used stably.
[0018] In another embodiment, such as Figure 4 As shown, a number of first reinforcing support blocks 25 are welded at equal intervals on the surface of the first reinforcing plate 24, a number of second reinforcing support blocks 27 are welded at equal intervals on the surface of the second reinforcing plate 26, and a number of third reinforcing support blocks 29 are welded at equal intervals on the surface of the third reinforcing plate 28.
[0019] The first reinforcing support block 25, the second reinforcing support block 27 and the third reinforcing support block 29 can strengthen the strength of the first reinforcing plate 24, the second reinforcing plate 26 and the third reinforcing plate 28, improve the overall stability and make them easy to use.
[0020] In another embodiment, such as Figure 4 As shown, the outer ends of the first reinforcing support plate 21 and the second reinforcing support plate 22 are in contact with the inner side of the fixing groove 210.
[0021] This allows for a thorough connection between the fixed groove 210 and the first reinforcing support plate 21 and the second reinforcing support plate 22.
[0022] In another embodiment, such as Figure 3 As shown, the connecting base 3 includes a connecting base plate 31, and the top of the connecting base plate 31 is symmetrically provided with a first limiting support block 32 and a second limiting support block 33.
[0023] The bottom plate 31, the first limiting support block 32 and the second limiting support block 33 are easy to connect and weld with the bottom of the outer plate 1 and the reinforcing structure 2, thereby strengthening the connection and making the whole stable for use.
[0024] In another embodiment, such as Figure 3 As shown, the inner side of the first limiting support block 32 and the inner side of the second limiting support block 33 are respectively in contact with the outer side of the bottom surface of the second reinforcing support plate 22 and the first reinforcing support plate 21.
[0025] This allows the first reinforcing support plate 21 and the second reinforcing support plate 22 to be inserted into the inner side of the second limiting support block 33 and the first limiting support block 32, and then welded and fixed, thus achieving a stable connection and making it convenient to use.
[0026] The working principle of this utility model is as follows: During use, firstly, the first reinforcing support plate 21 and the second reinforcing support plate 22 are inserted into the inner sides of the second limiting support block 33 and the first limiting support block 32, and then welded and fixed. Next, the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 are sequentially inserted into the inner side of the fixing slot 23. Welding is performed when the first reinforcing plate 24 is inserted into the fixing slot 23. Welding is then performed sequentially between the first reinforcing support plate 21, the second reinforcing support plate 22, the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28. Finally, the first reinforcing support plate 21 and the second reinforcing support plate 22 are welded to the outer plate 1. Simultaneously, the ends of the first reinforcing plate 24, the second reinforcing plate 26, and the third reinforcing plate 28 are welded and fixed to the outer plate 1. Finally, the connecting base plate 31 and the outer plate 1 are connected. The components are welded together to secure them, and the assembly is completed. When the assembly is in use, it can effectively disperse the impact force when subjected to external impact, effectively protecting the assembly and preventing deformation that could render it unusable. The overall structure is simple and the operation is convenient and quick.
[0027] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
