[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, the automobile rear pillar reinforcement comprises: a reinforcement mechanism 1, the reinforcement mechanism 1 comprises a reinforcement shell 11, a rear pillar body 12 is arranged at the bottom of the reinforcement shell 11, the bottom of the reinforcement shell 11 is docked at the outside of the rear pillar body 12, a plurality of buffer grooves 13 are provided at the top of the rear pillar body 12, a reinforcing rib 14 is arranged inside the rear pillar body 12, mounting grooves 15 are provided on both sides of the reinforcement shell 11, the rear pillar body 12 is fixedly connected with the reinforcing rib 14, the opposite sides of the two spring pieces are fixedly connected with the two sides of the inner wall of the mounting groove 15 respectively, and two buffer spring pieces 16 are arranged in the two mounting grooves 15. A reinforcement pad 17 is arranged between 16, and a plurality of positioning columns 18 are arranged on the top side of the inner wall of the reinforcement shell 11. The opposite sides of the two spring pieces are respectively fixedly connected to the two sides of the reinforcement pad 17, and the top of the positioning column 18 is fixedly connected to the top side of the inner wall of the reinforcement shell 11. Buffer springs 19 are arranged on the outside of the plurality of positioning columns 18, and movable blocks 110 are arranged on the bottom of the plurality of buffer springs 19. The bottom end of the positioning column 18 passes through the inner circle of the buffer spring 19 and is fixedly connected to the top of the movable block 110. One end of the buffer spring 19 is fixedly connected to the top side of the inner wall of the reinforcement shell 11, and the outside of the movable block 110 is clamped with the inner wall of the buffer groove 13. Fixing mechanisms 2 are arranged at both ends of the reinforcement shell 11.
[0023] In this embodiment, the reinforcing shell 11 can wrap and protect the rear pillar body 12. When the rear pillar body 12 is subjected to pressure from top to bottom, the pressure will be evenly dispersed outside the reinforcing shell 11, and then the reinforcing plate will press the positioning column 18 and the movable block 110 under pressure, so that the movable block 110 will be recessed into the buffer groove 13. At the same time, the end of the buffer spring 19 close to the movable block 110 will be squeezed and contacted with the top of the rear pillar body 12 due to the recess of the movable block 110, and then the buffer spring 19 will shrink and deform when squeezed. 9 can effectively disperse the external impact force and effectively reduce the risk of damage to the rear pillar body 12. When the impact force comes from both sides of the rear pillar body 12, the impact force will contact the side of the reinforcement shell 11, and then the impact force is converted into pressure to squeeze the buffer spring sheet 16 close to the outside of the reinforcement shell 11. When the squeezing degree of the buffer spring sheet 16 reaches the limit, the remaining pressure will be transmitted to the buffer spring sheet 16 away from the outside of the reinforcement shell 11 through the reinforcement pad 17. Therefore, the two buffer spring sheets 16 can achieve the effect of multiple pressure dispersion, reducing the risk of damage to the rear pillar body 12 caused by the impact force.
[0024] like Figure 1-Figure 4 As shown, the fixing mechanism 2 includes a fixing member 21, positioning grooves 22 are formed on both sides of the two ends of the reinforcement shell 11, and fixing grooves 23 are formed on both sides of the two ends of the rear column body 12. The fixing member 21 passes through the positioning groove 22 and is threadedly connected to the inner wall of the fixing groove 23.
[0025] In this embodiment, in order to ensure the connection state between the reinforcement shell 11 and the rear pillar body 12, the fixing piece 21 can be threadedly fixed through the positioning groove 22 opened on the reinforcement shell 11 and the fixing groove 23 opened on the outer side of the rear pillar body 12, thereby ensuring that the connection between the two is more stable and reliable, and at the same time, the time and cost of disassembly and installation during maintenance can be reduced.
[0026] The utility model provides a rear pillar reinforcement for an automobile, and the specific working principle is as follows:
[0027] When the rear pillar body 12 is subjected to pressure from top to bottom, this pressure will be evenly dispersed on the outside of the reinforcement shell 11. When the reinforcement plate is pressed downward, the movable block 110 will be recessed into the buffer groove 13. At the same time, the end of the buffer spring 19 close to the movable block 110 will be squeezed and contacted with the top of the rear pillar body 12 due to the depression of the movable block 110. This squeeze contact will cause the buffer spring 19 to shrink and deform, thereby playing a buffering role. When the impact force comes from both sides of the rear pillar body 12, this impact force will contact the side of the reinforcement shell 11. This contact will convert the impact force into pressure and squeeze the buffer spring piece 16 close to the outside of the reinforcement shell 11. When the squeezing degree of the buffer spring piece 16 reaches the limit, the remaining pressure will be transmitted to the buffer spring piece 16 away from the outside of the reinforcement shell 11 through the reinforcement pad 17. Therefore, through these two buffer spring pieces 16, the pressure can be effectively dispersed to achieve a multiple buffering effect. The fixing piece 21 passes through the positioning groove 22 and is threadedly fixed to the inner wall of the fixing groove 23, thereby ensuring that the connection between the reinforcement shell 11 and the rear column body 12 is more stable and reliable.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
