[0002] The hood is an important part of the front face of the car. Its main function is to protect the car engine and increase the aesthetics of the vehicle. The existing hood is usually hinged on the outside of the car. The hood is supported by an electric hydraulic rod or a support frame. The bottom of the hood is usually provided with multiple shock-absorbing rubber pads to prevent the hood from having excessive impact with the vehicle when it is closed.

[0003] The existing shock-absorbing rubber pad is usually set at the bottom of the hood by threaded connection. When the hood is closed, the shock-absorbing rubber pad is usually set at different heights, which makes it difficult for the hood and the car to be tightly closed, which reduces the overall aesthetics of the vehicle and affects the protection of the vehicle by the hood.

[0004] In the prior art, the hood and the vehicle are usually closed by repeatedly adjusting the heights of multiple sealing pads. However, due to the threaded connection, it is impossible to accurately adjust the heights of all the sealing pads to be uniform, which makes it difficult to close the hood and the vehicle, thereby reducing the protection effect of the hood on the vehicle.

[0033] The top of the cover body 1 is equipped with an air duct opening 11, and the bottom of the air duct opening 11 is embedded with a filter plate 13. The air duct opening 11 can collect the airflow generated when the vehicle is running, and the engine is cooled down by filtering through the filter plate 13. Both ends of the bottom of the cover body 1 are embedded with assembly plates 12, and the bottom of the assembly plate 12 is evenly distributed with assembly holes. The assembly plate 12 facilitates the assembly connection between the cover body 1 and the hydraulic rod.

[0034] See also Figure 3 and Figure 4 The assembly mechanism 3 includes a hollow sleeve 31, and the hollow sleeve 31 can assemble the shock-absorbing pad 41. Both ends of the hollow sleeve 31 are provided with card grooves 32, and the card grooves 32 can accommodate the limit blocks 47. Both ends of the hollow sleeve 31 are evenly provided with C-shaped grooves 33, and the C-shaped grooves 33 can be clamped to the limit blocks 47.

[0035] Blocks 34 are inserted at both ends of the hollow sleeve 31, and a first spring 35 is connected between the block 34 and the hollow sleeve 31. The block 34 can be inserted into the limit block 47 to connect the assembly mechanism 3 and the shock absorbing mechanism 4. The first spring 35 can drive the block 34 to move. There are four groups of slots 32.

[0036] There are two groups of blocks 34, which are assembled inside two groups of the slots 32. Then, the limit block 47 can be clamped by the shock-absorbing pad 41 after rotating 90°. The block 34 is trapezoidal in shape. When it is clamped into the limit block 47, the shock-absorbing pad 41 can be prevented from returning to its original position, thereby limiting the rotation of the shock-absorbing pad 41.

[0037] See also Figure 5The shock absorbing mechanism 4 includes a shock absorbing pad 41, both ends of which are connected to a limiting block 47, which can be inserted into the interior of the card slot 32 to fix the shock absorbing pad 41, and both ends of the interior of the shock absorbing pad 41 are provided with an I-shaped groove 42, which is slidably connected to the pressure plate 45 and the cross block 43.

[0038] The inside of the I-shaped groove 42 is connected to a short shaft through a seat bearing, and the outside of the short shaft is connected to a telescopic rod 44.

[0039] A measuring plate 48 is embedded in the front of the shock-absorbing pad 41, and a scale line is arranged on the outside of the measuring plate 48. The measuring plate 48 can facilitate the staff to observe the length of the shock-absorbing mechanism 4 entering the assembly mechanism 3, and then accurately adjust the height of all the shock-absorbing mechanisms 4 to be unified. The measuring plate 48 is made of acrylic material, and numbers are arranged on the outside of the scale line. The numbers improve the viewing precision. The air duct opening 11 is an arc-shaped design, and the filter plate 13 is slidably arranged at the bottom of the cover body 1. The arc shape improves the air intake effect, and the sliding arrangement facilitates the removal of the filter plate 13. The bottom of the cover body 1 is equipped with rubber foam, and the top of the cover body 1 is provided with an aluminum foil plate. The top of the shock-absorbing pad 41 is a hard polyvinyl chloride plastic block, and the bottom of the shock-absorbing pad 41 is a polyvinyl chloride block.

The second clamping is completed. When the shock-absorbing mechanism 4 needs to be disassembled, the horizontal block 43 is pressed toward the inside of the shock-absorbing pad 41, and then the telescopic rod 44 is driven to rotate, driving the pressing plate 45 to move, and the block 34 inserted into the limit block 47 is pressed out, and then the restriction of the block 34 on the shock-absorbing pad 41 is released. At this time, the shock-absorbing pad 41 can be rotated again to adjust the height or disassemble and maintain;

[0041] When the cover body 1 is assembled and used, the assembly mechanism 3 and the shock-absorbing mechanism 4 can be quickly connected through the added assembly mechanism 3 and the shock-absorbing mechanism 4 through a double clamping method, and the height of the shock-absorbing mechanism 4 can be quickly adjusted to make the height of the shock-absorbing mechanism 4 at the bottom of the cover body 1 uniform, thereby avoiding the inability to unify the height of the shock-absorbing mechanism 4 caused by the traditional threaded connection to fix the shock-absorbing mechanism 4, which causes the cover body 1 to be unable to be completely closed with the vehicle, thereby reducing the protection performance of the cover body 1, and at the same time increasing the stability of the connection between the assembly mechanism 3 and the shock-absorbing mechanism 4, thereby avoiding the shock-absorbing mechanism 4 from falling off from the inside of the cover body 1 through the traditional threaded connection when the vehicle is bumpy. At the same time, the cover body 1 is made of rubber foam and aluminum foil materials to increase the overall strength performance.
