Generally, there are three pillars on the car body, from front to back, they are the front pillar (A-pillar), the middle pillar (B-pillar) and the rear pillar (C-pillar). For cars, the pillars not only play a supporting role, but also act as door frames.
[0003] The existing A-pillar stamping parts have a single anti-collision structure. When encountering a large impact force, the A-pillar stamping parts may bend, affecting safety.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0026] like Figures 1 to 4As shown, the A-pillar stamping part of the automobile body includes a main body 1 with a buffer mechanism 2 arranged inside, a main body forearm 11 is arranged above the main body 1, and the front end of the main body forearm 11 is wavy, a main body tail 12 is arranged at the rear of the main body 1, and the upper part of the main body tail 12 is connected to the side in a seven-shaped shape, the main body tail 12 is rectangular, and the main body tail 12 and the main body forearm 11 are integrally cast; in this arrangement, the wavy design of the main body forearm 11 enables better production of the A-pillar, and the seven-shaped design of the main body tail 12 makes the main body 1 stable, and can unload most of the collision force from the top and the side.
[0027] The buffer mechanism 2 includes five buffer iron plates 21, which are installed in the interlayer of the main body 1, and a gap is left between the fourth buffer iron plate 21 and the fifth buffer iron plate 21 located on the outside of the main body 1; in this setting, the design of the next layer of the four layers above the buffer iron plate 21 can disperse the collision force.
[0028] A cylinder 22 is provided inside the main body 1 , and the cylinder 22 is installed in the above-mentioned gap; in this configuration, most of the force applied to the cylinder 22 acts on the cylinder 22 .
[0029] A plurality of groups of reinforcing ribs 3 are provided inside the main body 1; in this arrangement, the reinforcing ribs 3 strengthen the overall structure of the A-pillar.
[0030] The main body 1 is provided with two groups of positioning holes 4. In this arrangement, the positioning holes 4 make the A-pillar connection more convenient.
[0031] like Figures 1 to 4 As shown, there are three locating holes 4. The three locating holes 4 are in the form of an equilateral triangle. In this configuration, the locating holes 4 are in the form of an equilateral triangle, which makes the A-pillar connection stable.
[0032] like Figures 1 to 4 As shown, further, the buffer iron plate 21 is arched, and the buffer iron plate 21 is installed in layers inside the main body 1. In this arrangement, the multi-layer design of the buffer iron plate 21 can unload the force layer by layer, so that the A-pillar is least damaged.
[0033] like Figures 1 to 4 As shown, further, the number of the positioning holes 4 is two, and the positioning holes 4 are distributed on the left and right sides of the main body 1 and penetrate one side of the main body 1. In this configuration, the two positioning holes 4 provide stability to the front and rear of the A-pillar.
[0034] like Figures 1 to 4 As shown, further, the number of reinforcing ribs 3 at the front end of the main body 1 is three, and the first two reinforcing ribs 3 are cross-mounted, and the number of reinforcing ribs 3 at the rear end of the main body 1 is four, and the reinforcing ribs 3 are arranged in parallel on the main body 1. In this configuration, the reinforcing ribs 3 strengthen the hardness of the A-pillar.
[0035] like Figures 1 to 4 As shown, further, each layer of the buffer iron plate 21 has a gap with the previous layer of buffer iron plate 21, and the gap between the fourth layer of buffer iron plate 21 and the fifth layer of buffer iron plate 21 is larger than the gaps between other buffer iron plates 21. In this setting, the gap setting of the buffer iron plate 21 makes it difficult for the iron plate to break.
[0036] The implementation principle of the automobile body A-pillar stamping part of this embodiment is as follows: when the automobile A-pillar collides, the force of the front collision first passes through the A-pillar main body front arm 11. The wavy design of the main body front arm 11 makes the A-pillar not easy to bend, and then passes through the surface of the main body 1 to the first layer of buffer iron plate 21, and then passes from the first layer of buffer iron plate 21 to the second layer of buffer iron plate 21, and then passes through the third layer of buffer iron plate 21 to the fourth layer of buffer iron plate 21 and then acts on the cylinder 22. At this time, the cylinder 22 buffers a large part of the force and finally passes through the last layer of buffer iron plate 21 to reach the bottom of the A-pillar main body 1, unloading most of the force. The seven-shaped design of the main body tail 21 makes the A-pillar integrated, the reinforcing rib 3 strengthens the hardness of the A-pillar, ensures the integrity of the A-pillar, and improves safety. The positioning hole 4 makes the A-pillar connection more convenient and the positioning hole 4 is an equilateral triangle, so that the left and right connection of the A-pillar is stable.
