Description

Technical Field

[0001] The invention relates to the technical field of frame energy absorption and buffering, in particular to a high-strength energy absorption frame. Background Art

[0002] The frame is a frame structure that spans the front and rear axles of the car, commonly known as the beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels through the suspension device, the front axle, and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, so that each assembly maintains a relatively correct position, and withstands various loads inside and outside the car.

[0003] The structural form of the frame should first meet the requirements of the overall layout of the vehicle. During the complex driving process of the vehicle, there should be no interference between the assemblies and components fixed on the frame. When the vehicle is driving on a rough road, the frame may produce torsional deformation and bending deformation in the longitudinal plane under the action of load; when one wheel encounters an obstacle, the entire frame may be twisted into a diamond shape. These deformations will change the relative positions of the components installed on the frame, thereby affecting their normal operation. Therefore, the frame should also have sufficient strength and appropriate rigidity. In order to improve the lightweight level of the entire vehicle, the frame mass is required to be as small as possible. In addition, the frame should be arranged closer to the ground to lower the center of gravity of the vehicle, which is conducive to improving the driving stability of the vehicle. This is especially important for buses and cars.

[0004] Most of the components and assemblies of a car are fixed by the frame, such as the engine, transmission system, suspension, steering system, cab, cargo box and related operating mechanisms. The frame supports and connects the various components of the car and bears various loads from inside and outside the car.

[0005] High-strength boron steel is four times harder than ordinary steel, and its strength, toughness and wear resistance are also better than ordinary steel. Early tanks, armored vehicles and submarines all used it, until lighter and stronger materials appeared, so boron steel was transferred to civilian use. Now it is widely used in machine tool cutters and mining machine drills. When used in the chassis and body of automobiles, it can improve the rigidity and hardness of the frame and reduce the casualties of passengers in the car caused by deformation in car accidents.

[0006] In the prior art, publication number "CN103465965B" discloses a high-strength and lightweight vehicle frame, wherein the vehicle frame body is an integrated frame structure, which includes a box structure, a cockpit located in front of the box structure, and a diagonal structure at the rear of the box structure. The box structure includes an upper rectangular frame and a lower rectangular frame, which are composed of a plurality of vertical rods and a plurality of diagonal rods, and the cockpit is provided with an arc-shaped cockpit bottom cabin. The invention has the characteristics of high strength and low weight, and has strong impact resistance.

[0007] However, the existing technology still has major deficiencies, such as:

[0008] In the above-mentioned device and the prior art, the lightweight frame is often used in the field of small car manufacturing such as solar cars and electric cars. When a small car is in use, it is easy for novices to operate due to its small size. However, when the lightweight frame of the small car encounters a vehicle collision, the lightweight frame cannot absorb the energy suffered by the front end of the cockpit and collapse, resulting in the cockpit of the small car being directly impacted, thereby affecting the protective effect of the cockpit of the small car.

[0046] The front frame anti-collision energy absorption buffer unit also includes an anti-collision part, which includes a front anti-collision arm 5, which is installed at one end of the front energy absorption frame 3. The surface of the front anti-collision arm 5 is provided with a front buffer rib groove 51, and the front buffer rib grooves 51 are vertically arranged in a plurality of groups.

[0047] In this embodiment, the front anti-collision arm 5 will disperse and release the impact it receives through multiple groups of front buffer rib grooves 51. Part of the impact force will be consumed under the slow release of the front buffer rib grooves 51, and part of the impact force will enter the front energy absorption box 71 area under the guidance of the front anti-collision arm 5.

[0049] The frame energy absorption and anti-collapse unit includes an anti-collapse part one, which includes an anti-collapse front long arm 32. A buffer cavity 31 is provided on the surface of the front section of the energy absorption frame 3. The anti-collapse front long arms 32 are arranged in three groups at intervals.

[0054] In the present embodiment, after the rear section energy absorbing frame 1 partially exceeds the bearing upper limit of the material, the rear section energy absorbing frame 1 region will produce energy absorption collapse, and the rear bottom cover 13 installed at the bottom of the rear section energy absorbing frame 1 can first reduce the partial collapse of the rear section energy absorbing frame 1, and at the same time, three groups of buffer rear arms 12 are installed at intervals in adjacent energy absorbing cavities 11, and the three groups of buffer rear arms 12 can gradually reduce the energy absorption collapse problem of the rear section energy absorbing frame 1, ensuring the material integrity of the buffer rear arms 12.

[0055] Embodiment 2:

[0056] Based on the first embodiment, in this embodiment, it is considered that if the central support frame 2 area absorbs energy and collapses severely after being impacted, the rear passenger compartment above the central support frame 2 cannot be opened normally. Therefore, in this embodiment, a central frame lateral impact multi-end buffer unit is provided to reduce the impact on the central support frame 2.

[0057] The multi-end buffer unit for lateral impact of the middle frame is arranged in the internal area of ​​the middle supporting frame 2. It is used to deal with the lateral impact of the middle supporting frame 2 area by dispersing the lateral impact of the middle supporting frame 2 into multiple end areas to achieve the purpose of buffering and energy absorption in the middle supporting frame 2 area.

[0058] The middle frame lateral impact multi-end buffer unit includes a reinforcement part, which includes a reinforcement frame 21. The reinforcement frame 21 is arranged in a plurality of groups at intervals. The reinforcement frame 21 is sleeved on the surface of the middle support frame 2. A reinforcement frame 22 is installed on one side of the reinforcement frame 21, and the reinforcement frame 22 is arranged in a U shape.

[0059] The mid-frame lateral impact multi-end buffer unit also includes a buffer portion, which includes a lateral support arm 4, which is arranged in an arc shape, and adjacent lateral support arms 4 are fixed by lateral support blocks 41, and the lateral support blocks 41 are arranged in a plurality of groups at intervals. An outer covering bin 42 is sleeved and installed on the outer surface of the lateral support arm 4, and rectangular grooves 43 are evenly arranged on the outer surface of the outer covering bin 42.

[0060] In this embodiment, multiple groups of reinforcement frames 21 can ensure the multi-point distribution of the lateral support arms 4. Adjacent lateral support arms 4 are fixed by lateral support blocks 41. The multi-point distributed lateral support arms 4 can support and buffer the inner side of the central support frame 2, thereby reducing the energy absorption and collapse problem caused by the impact on the central support frame 2 area, and ensuring the energy absorption and buffering effect of the central support frame 2.

[0061] Working principle: When the device is in use, the front energy-absorbing frame 3 is located in the front end area of ​​the vehicle body. The front anti-collision arm 5 on the outside of the front energy-absorbing frame 3 can ensure that when the front end of the vehicle body encounters an impact, the front anti-collision arm 5 will disperse and release the impact through multiple groups of front buffer rib grooves 51. Part of the impact force will be consumed under the slow release of the front buffer rib grooves 51, and part of the impact force will enter the front energy-absorbing net box 71 area under the guidance of the front anti-collision arm 5. The three-layer energy-absorbing cotton block layer 72 inside the front energy-absorbing net box 71 can further release and absorb the impact force, thereby ensuring the energy absorption and buffering effect of the front energy-absorbing frame 3.

[0062] When the front end of the front energy-absorbing frame 3 is impacted, the impact force will be dispersed in the front energy-absorbing net box 71 and the front anti-collision arm 5 area, and the impact force through the front energy-absorbing net box 71 and the front anti-collision arm 5 will enter the front energy-absorbing frame 3 area. When the impact force exceeds the material bearing limit of the front energy-absorbing frame 3, the front energy-absorbing frame 3 will collapse. In order to reduce the deformation of the cockpit area caused by the collapse of the front energy-absorbing frame 3, the buffer cavity 31 area on the front energy-absorbing frame 3 is provided with an anti-collapse front long arm 32 and an anti-collapse front short arm 33. The two groups of anti-collapse front short arms 33 are compositely installed on the inner sides of the three groups of anti-collapse front long arms 32. At the same time, the two groups of anti-collapse front short arms 33 and the three groups of anti-collapse front long arms 32 are directly transversely reinforced with transverse rods 34, which can effectively deal with the collapse problem of the front energy-absorbing frame 3 in different directions, thereby ensuring the integrity of the cockpit above the front energy-absorbing frame 3 and further improving the energy absorption and anti-collapse effect of the front energy-absorbing frame 3.

[0063] When the middle support frame 2 is impacted from the side, the surfaces of the two groups of middle support frames 2 are installed with reinforcement frames 21, and the reinforcement frames 22 inside the reinforcement frames 21 can be installed on the lateral support arms 4. At the same time, multiple groups of reinforcement frames 21 can ensure the multi-point distribution of the lateral support arms 4, and the adjacent lateral support arms 4 are fixed by lateral support blocks 41. The multi-point distributed lateral support arms 4 can support and buffer the inner side of the middle support frame 2, thereby reducing the energy absorption and collapse problem caused by the impact on the middle support frame 2 area, and ensuring the energy absorption and buffering effect of the middle support frame 2;

[0064] When the rear section energy absorbing frame 1 is hit by a rear-end collision, the energy absorbing cavity 11 of the rear section energy absorbing frame 1 will absorb energy first. After the energy absorbing cavity 11 absorbs energy, when the rear section energy absorbing frame 1 exceeds the upper limit of the material, the rear section energy absorbing frame 1 will produce energy absorption collapse. The rear bottom cover 13 installed at the bottom of the rear section energy absorbing frame 1 can first reduce the partial collapse of the rear section energy absorbing frame 1. At the same time, three groups of buffer rear arms (12) are installed in adjacent energy absorbing cavities 11 at intervals. The three groups of buffer rear arms (12) are all arranged in an arc shape. The three groups of buffer rear arms (12) can gradually reduce the energy absorption collapse problem of the rear section energy absorbing frame 1, and ensure the integrity of the material of the buffer rear arms (12).

[0065] 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.
