[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0022] Reference Figure 1-3 A car tailgate reinforcement structure includes a main structure plate 1, a connecting plate 2 is installed on the front side of the main structure plate 1, a honeycomb frame 5 is provided on the upper side of the connecting plate 2, a movable plate 3 is installed on the front side of the connecting plate 2, and an arc-shaped external connecting plate 9 is provided on the rear side surface of the connecting plate 2.
[0023] Connectors 6 are fixedly installed on both side surfaces of the main structure plate 1. A plurality of mounting holes 7 are opened on the surface of the connecting member 6. Fixing bolts 8 are passed through the plurality of mounting holes 7. The fixing bolts 8 are threadedly connected to the mounting holes 7. The main structure plate 1 is fixedly connected to the main structure of the automobile tailgate through the fixing bolts 8.
[0024] The main structure plate 1 is stably connected to the main structure of the automobile tailgate by fixing bolts 8, and the reinforcement structure is installed outside the automobile tailgate. If the reinforcement structure is damaged, only the reinforcement structure needs to be replaced, thereby reducing the cost of automobile maintenance.
[0025] A plurality of connecting adhesive strips 12 are adhered to the front surface of the main structure panel 1 , and the other side of the connecting adhesive strips 12 is adhered to the rear surface of the connecting panel 2 , so as to stably connect the main structure panel 1 and the connecting panel 2 .
[0026] A reserved groove 4 is provided on the front surface of the connecting plate 2, and a plurality of shock absorbers 11 are fixedly installed on the inner surface of the reserved groove 4. The rear surface of the movable plate 3 is fixedly connected to the ends of the shock absorbers 11, and the front surface of the movable plate 3 fits the main structure of the car tailgate.
[0027] When the car is hit, the movable plate 3 moves synchronously with the shock absorber 11 to buffer the external impact, thereby reducing the impact on the tailgate and the main body of the car.
[0028] The bottom of the honeycomb frame 5 is fixedly connected to the upper surface of the connecting plate 2, and a rubber pad is fixedly installed on the front surface of the honeycomb frame 5. The honeycomb frame 5 disperses the external impact force on the reinforced structure and reduces the impact of strong impact on the car body.
[0029] The external connecting plate 9 is fixedly installed on the rear lower surface of the main structure plate 1, and a buffer pad 10 is fixedly installed inside the external connecting plate 9. The buffer pad 10 has a plurality of through holes formed inside to enhance the overall buffering and protection effects.
[0030] Working principle: When in use, the main structure plate 1 is stably connected to the main structure of the automobile tailgate by fixing bolts 8. The reinforcement structure is installed outside the automobile tailgate. If the reinforcement structure is damaged, only the reinforcement structure needs to be replaced, thereby reducing the cost of automobile maintenance. When the automobile is hit, the movable plate 3 moves synchronously with the shock absorber 11 to buffer the external impact. The honeycomb frame 5 disperses the external impact force on the reinforcement structure, thereby reducing the impact of strong impact on the automobile body. If the reinforcement structure is damaged, only the reinforcement structure needs to be replaced, thereby reducing the probability of replacing the automobile tailgate and reducing the cost of overall automobile maintenance.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
