[0002] The car door is a very important part of a car, and its safety performance is crucial. Existing car doors have metal anti-collision beams installed in their internal cavities. When a side collision occurs, the anti-collision beams can resist the impact of the side collision and reduce injury to the occupants. However, because the anti-collision beams in the current technology will break after being impacted, and the anti-collision beams cannot buffer the impact force, their safety protection capability is insufficient. Utility Model Content

[0003] In view of this, this application provides a built-in buffer frame for automobile doors to solve the technical problem that the anti-collision beams in the prior art break after being impacted, and the anti-collision crossbeams cannot buffer the impact force, thus resulting in insufficient safety protection capabilities.

[0016] A first compression spring is connected between the buffer cylinder and the sliding plate;

[0017] A connecting rod, which connects the sliding plate and the buffer plate.

[0018] Furthermore, a cover plate is installed on the buffer cylinder, which restricts the sliding plate inside the buffer cylinder.

[0019] Furthermore, the second buffer component includes:

[0020] Guide member, the guide member being mounted on the reinforcing plate;

[0021] A pair of elastic sliding members are symmetrically mounted on the guide member, and the pair of elastic sliding members slide in cooperation with the guide member;

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0043] refer to Figures 1 to 6 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a built-in buffer frame for an automobile door, including: a back plate 1, a plurality of first buffer components 8, a plurality of second buffer components 9, a buffer plate 3, and a buffer pad 7. A plurality of ear plates 2 are integrally connected to the upper and lower sides of the back plate 1, and the ear plates 2 can be installed in the hollow inner cavity of the door; a plurality of first buffer components 8 are spaced apart and installed on the back plate 1; a plurality of second buffer components 9 are spaced apart and installed on the back plate 1; the buffer plate 3 is connected to the plurality of first buffer components 8 and the plurality of second buffer components 9; and the buffer pad 7 is installed on the buffer plate 3.

[0044] Preferably, in order to enhance the overall buffering capacity, the built-in buffer frame for the car door also includes several pairs of buffer elastic plates 4. Each pair of buffer elastic plates 4 is symmetrically connected between the back plate 1 and the buffer plate 3. The number of buffer elastic plates 4 can be set according to the length of the back plate 1 and the buffer plate 3.

[0045] Specifically, such as Figure 4 As shown, the buffer elastic plate 4 includes a first mounting part 41, an arc-shaped elastic part 42, and a second mounting part 43 connected in sequence. The first mounting part 41 is mounted on the back plate 1, and the second mounting part 43 is mounted on the buffer plate 3.

[0046] Preferably, in order to enhance the impact resistance of the back plate 1, the built-in buffer frame for the car door also includes a reinforcing plate 5. The reinforcing plate 5 is installed on the back plate 1 and is connected to the back plate 1 by bolts 12. After the bolts 12 pass through the reinforcing plate 5, they are locked by nuts 6 to ensure a secure connection between the reinforcing plate 5 and the back plate 1. The left ends of several first buffer components 8 and several second buffer components 9 are installed on the reinforcing plate 5, and the right ends of several first buffer components 8 and several second buffer components 9 are connected to the buffer plate 3.

[0047] Preferably, in order to save installation space, the back plate 1 is provided with a groove 11 for accommodating the head of the bolt 12.

[0048] like Figure 5As shown, the first buffer assembly 8 includes: a buffer cylinder 81, a sliding plate 83, a first compression spring 84, and a connecting rod 85. The buffer cylinder 81 is fixed on the reinforcing plate 5; the sliding plate 83 is slidably connected to the buffer cylinder 81; the first compression spring 84 is connected between the buffer cylinder 81 and the sliding plate 83; and the connecting rod 85 is connected between the sliding plate 83 and the buffer plate 3.

[0049] Preferably, two grooves 811 are formed opposite to each other on the inner wall of the buffer cylinder 81, and the two ends of the sliding plate 83 slide in cooperation with the two grooves 811 so that the connecting rod 85 moves smoothly.

[0050] In this embodiment of the application, a cover plate 82 is installed on the buffer cylinder 81. The cover plate 82 restricts the sliding plate 83 inside the buffer cylinder 81, which can solve the problem of inconvenient installation of the sliding plate 83 and restrict the sliding plate 83.

[0051] When the buffer plate 3 is impacted, the buffer plate 3 will squeeze the connecting rod 85. The connecting rod 85 will then drive the sliding plate 83 to move to the left along a pair of sliding grooves 811, thereby squeezing the first compression spring 84. Thus, the first compression spring 84 will produce an elastic buffering effect.

[0052] like Figure 6 As shown, the second buffer assembly 9 includes: a guide member, a pair of elastic sliding members, and a trapezoidal plate 92. The guide member is installed on the reinforcing plate 5 and is spaced apart from the buffer cylinder 81. The pair of elastic sliding members are symmetrically installed on the guide member and are in sliding engagement with the guide member. The trapezoidal plate 92 is connected to the buffer plate 3 by a protruding rod 91 and is in sliding engagement with both the trapezoidal plate 92 and the pair of elastic sliding members.

[0053] In this embodiment, the elastic sliding member includes: a trapezoidal block 96, a spring seat 97, and a second compression spring 95. A trapezoidal plate 92 is slidably connected between a pair of trapezoidal blocks 96. By moving the trapezoidal plate 92 horizontally, the pair of trapezoidal blocks 96 can be driven to move relative to each other in the vertical direction. The spring seat 97 is installed in the through hole 961 of the corresponding trapezoidal block 96, and the spring seat 97 is slidably sleeved on the guide member. The second compression spring 95 is connected between the spring seat 97 and the guide member.

[0054] In this embodiment, the guide includes a pair of mounting plates 93 and a slide rod 94. The pair of mounting plates 93 are spaced apart on the reinforcing plate 5, and the slide rod 94 is vertically connected between the pair of mounting plates 93.

[0055] In this embodiment, a pair of spring seats 97 and a pair of second compression springs 95 are both sleeved on the slide rod 94, and the second compression springs 95 are connected between the corresponding spring seats 97 and the corresponding mounting plates 93.

[0056] When the buffer plate 3 is impacted, the buffer plate 3 will squeeze the trapezoidal plate 92 through the protrusion 91, so the trapezoidal plate 92 moves to the left, causing a pair of trapezoidal blocks 96 to move away from each other. Then the corresponding spring seat 97 moves to the mounting plate 93 on the corresponding side, so the second compression spring 95 is squeezed, and the second compression spring 95 produces an elastic buffering effect.

[0057] Working principle: This application is installed inside the hatch. When a car is involved in a side collision, the hatch is subjected to squeezing impact. The impact force is transmitted to the inside of the hatch, first squeezing the buffer pad 7, causing it to deform. As the impact continues to be transmitted into the hatch, the buffer pad 7 drives the buffer plate 3 to move to the left. The leftward movement of the buffer plate 3 squeezes several buffer elastic plates 4, several first buffer components 8, and several second buffer components 9. Thus, the several buffer elastic plates 4, several first buffer components 8, and several second buffer components 9 generate elasticity to resist the impact. Since a reinforcing plate 5 is set between the several buffer elastic plates 4, several first buffer components 8, and several second buffer components 9 and the back plate 1, the reinforcing plate 5 can resist the impact, thereby reducing the deformation of the back plate 1. Since the back plate 1 is close to the occupants of the vehicle, it can reduce the injury to the occupants of the vehicle in a side collision and improve the safety protection effect.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
