Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle doors, in particular to a high-strength heavy vehicle door accessory. Background Art

[0002] The vehicle door provides a passage for the driver and passengers to enter and exit the vehicle, isolates the vehicle from interference, and protects the occupants in the event of a side impact. Its anti-collision performance is particularly important because the buffer distance is very short when the vehicle collides from the side, so it is easy to injure the people inside the vehicle. Existing vehicle doors are composed of a door body and door inner panel interior trims. Therefore, the structural strength and protective performance of the door and door inner panel trims play a vital role in the side collision of the vehicle. Utility Model Content

The door inner panel has high structural strength and good protective performance, and can effectively protect the driver and passengers in a side collision.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: a high-strength heavy-duty automobile door accessory, comprising a door inner panel, wherein two buffer boxes arranged horizontally are symmetrically arranged in the middle position of the front end surface of the door inner panel, the two buffer boxes are arranged at intervals up and down, and guide slide grooves are horizontally opened on the inner walls on both sides of the buffer box, a buffer block is arranged inside the buffer box, and guide sliding blocks matching the guide slide grooves are arranged on both sides of the buffer block, and a plurality of first buffer components are evenly arranged at intervals along the length direction of the front end surface of the buffer block, and the free end of the first buffer component is in conflict with the front end surface inside the buffer box, and a plurality of second buffer components are evenly arranged between the rear end surface of the buffer block and the rear end surface inside the buffer box, and the buffering direction of the second buffer component is the same as that of the first buffer component.

[0005] Furthermore, the buffer box includes a front box body and a rear cover arranged on the rear end surface of the front box body.

[0006] Further, the first buffer assembly includes a buffer cylinder, a buffer rod, a pressure block, and a first buffer spring, wherein the buffer cylinder is arranged on the front end surface of the buffer block, one end of the buffer rod contacts the front end surface inside the buffer box, and the other end extends into the buffer cylinder, the pressure block is arranged on the buffer rod inside the buffer cylinder, and the first buffer spring is arranged inside the buffer cylinder and contacts the pressure block.

[0007] Furthermore, a front end surface of the buffer block is provided with a receiving groove matching the buffer tube.

[0008] Furthermore, the second buffer assembly includes a first connecting block, a second connecting block, and a second buffer spring. The first connecting block is arranged on the rear end surface of the buffer block, and the second connecting block is arranged on the front end surface of the rear cover. The first connecting block and the second connecting block are on the same central axis, and both ends of the second buffer spring are respectively mounted on the first connecting block and the second connecting block.

[0009] Furthermore, a plurality of cross-arranged reinforcing ribs are provided on the door inner panel.

[0010] Furthermore, guide rails are arranged at intervals at the bottom end inside the buffer box, and the bottom end of the buffer block is slidably connected to the guide rails.

[0011] The beneficial effects of the utility model are:

[0012] The utility model cooperates with the buffer box, the guide slide groove, the guide slider, the buffer block, the first buffer component and the second buffer component in setting. After the vehicle door is deformed by impact, the impact force is first transmitted to the front end surface of the buffer box. The front end surface of the buffer box first resists the impact and deforms to release the impact force. As the front end surface of the buffer box collapses backward, the impact force is transmitted to the first buffer component to further relieve the impact force. The impact force is then transmitted to the buffer block. The buffer block moves backward along the guide slide groove through the guide slider and squeezes the second buffer component to relieve the impact force again. Finally, the impact force is transmitted to the inner panel of the door. The utility model can relieve the external impact force multiple times. The mutual cooperation effectively improves the protective performance of the inner panel of the door and the door, and effectively protects the driver and passengers in side collisions.

After the front end surface of the buffer box 2 resists and relieves the impact force, when the compression deformation occurs, the buffer box 2 squeezes the first buffer component to reduce the impact force again. A plurality of second buffer components are evenly arranged between the rear end surface of the buffer block 4 and the rear end surface inside the buffer box 2. The buffering direction of the second buffer component is the same as that of the first buffer component. After the first buffer component relieves the external impact force, the impact force is transmitted to the buffer block 4, driving the buffer block 4 and the guide slider 301 to move horizontally backward along the guide slide groove 3, squeezing the second buffer component, releasing the external impact force again, and finally transmitting it to the door inner panel 1.
