Description

Technical Field

[0001] The utility model relates to the field of automotive engineering, in particular to a main - secondary integrated structure frame with impact resistance. Background Technique

[0002] The frame is generally composed of longitudinal beams and cross - beams. Its forms mainly include side - beam type and center - beam type. The side - beam type frame is composed of two longitudinal beams on both sides and several cross - beams, and the longitudinal beams and cross - beams are connected into a rigid framework by riveting or welding.

[0003] Most of the existing frames simply rely on the connection between cross - beams and longitudinal beams to resist impact force, resulting in poor impact resistance of the frame. At the same time, most of the existing cross - beams and vertical beams of the frame are fixed in length and cannot be adjusted according to the actual situation, which will cause waste of time and resources. Therefore, those skilled in the art provide a main - secondary integrated structure frame with impact resistance to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a main - secondary integrated structure frame with impact resistance, which improves the overall impact resistance of the frame by setting buffer devices on both sides of the frame bumper. It has high safety and is easy to operate.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A main - secondary integrated structure frame with impact resistance, including two first bumpers. On both sides of the opposite inner surfaces of the two first bumpers, two rubber buffers are fixedly arranged. On the opposite inner surfaces of the two rubber buffers, a second bumper is fixedly arranged. On both sides of the opposite inner surfaces of the two second bumpers, two storage boxes are fixedly arranged. Rubber plugs are snap - fitted on the rear ends of the four storage boxes. On the opposite inner surfaces of the two second bumpers, two vertical beams are fixedly arranged. At the front and rear ends of the inner sides of the two vertical beams, a plurality of first cross - beams are fixedly arranged. In the middle of the inner sides of the two vertical beams, a second cross - beam is fixedly arranged.

[0006] Further, a first sliding rod is slidably arranged on the inner wall of the rubber buffer. A baffle is fixedly arranged on the rear end surface of the first sliding rod. A second sliding rod is fixedly arranged on the rear end surface of the baffle.

[0007] Further, a buffer liquid is movably arranged between the baffle and the storage box.

[0008] Further, two filter meshes are fixedly arranged between the plurality of first cross - beams and the second bumper.

[0009] Further, the first cross - beam includes a first inner beam, and first outer beams are slidably arranged on both sides of the first inner beam.

[0010] Furthermore, a plurality of screw holes are equidistantly formed on the surface of the first inner beam, and bolts are threadedly sleeved on the inner walls of the plurality of screw holes, and nuts are threadedly sleeved on the lower ends of the plurality of bolts.

[0011] Furthermore, the second cross beam includes a second inner beam, and second outer beams are slidably arranged on both sides of the second inner beam.

[0012] The utility model has the following beneficial effects:

[0013] 1. For a shock-resistant main and auxiliary integrated structure vehicle frame proposed by the utility model, by installing a rubber buffer and a storage box at the vehicle frame bumper, when the bumper is impacted, part of the impact force will be consumed by the rubber buffer, and the remaining impact force will push the baffle through the first sliding rod to squeeze the buffer liquid in the storage box, converting it into the kinetic energy of the buffer liquid. The buffer liquid is discharged through the notch at the rear end of the storage box to release the kinetic energy, thereby improving the shock resistance of the vehicle frame.

[0014] 2. For a shock-resistant main and auxiliary integrated structure vehicle frame proposed by the utility model, by dividing the cross beam and the vertical beam into two parts, namely the outer beam and the inner beam, the inner beam and the outer beam can slide and are connected by bolts and nuts. In this way, the lengths of the cross beam and the vertical beam can be adjusted, and further the length and width of the vehicle frame can be adjusted, so as to adapt to more vehicle models. At the same time, filters are added at the front and rear sections of the vehicle frame respectively, which can effectively prevent foreign objects from entering the vehicle body during the driving of the vehicle, thereby increasing the service life of the vehicle.

Detailed implementation

[0024] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figure 1 , Figure 2 , Figure 7 , an embodiment provided by the present invention: a shock-resistant main and auxiliary integrated structure vehicle frame, including two first bumpers 1. On both sides of the inner opposite surfaces of the two first bumpers 1, two rubber buffers 2 are fixedly arranged. On the inner opposite surfaces of the two rubber buffers 2, a second bumper 3 is fixedly arranged. On both sides of the inner opposite surfaces of the two second bumpers 3, two storage boxes 4 are fixedly arranged. Rubber plugs 16 are clamped on the rear ends of the four storage boxes 4. On the inner opposite surfaces of the two second bumpers 3, two vertical beams 7 are fixedly arranged. At the front and rear ends of the inner sides of the two vertical beams 7, a plurality of first cross beams 6 are fixedly arranged. In the middle of the inner sides of the two vertical beams 7, a second cross beam 8 is fixedly arranged;

[0026] Specifically, when the vehicle frame is impacted, the first bumper 1 will squeeze the rubber buffer 2 inward, converting part of the impact force into the elastic potential energy of the rubber, thereby initially offsetting the impact force.

[0027] A first sliding rod 12 is slidably arranged on the inner wall of the rubber buffer 2. A baffle 13 is fixedly arranged on the rear end surface of the first sliding rod 12. A second sliding rod 14 is fixedly arranged on the rear end surface of the baffle 13. A buffer liquid 15 is movably arranged between the baffle 13 and the storage box 4;

[0028] Specifically, when the first bumper 1 squeezes inward, it will drive the first sliding rod 12 to squeeze the baffle 13, causing the baffle 13 to slide inward. At the same time, the baffle 13 drives the second sliding rod 14 to slide inward. When the second sliding rod 14 slides inward to a certain distance, it will push out the rubber plug 16, thereby opening the gap at the back of the storage box 4. By the inward sliding of the baffle 13, the buffer liquid 15 is pushed out through the gap at the back of the storage box 4, converting the impact force into the kinetic energy of the buffer liquid 15 and releasing it, further offsetting the impact force.

[0029] There are two filters 5 fixedly arranged between multiple first crossbeams 6 and the second bumper 3;

[0030] Specifically, by adding filters 5 between the second bumper 3 at the front end of the vehicle frame and the first crossbeams 6 and between the three first crossbeams 6 at the rear end of the vehicle frame respectively, foreign objects driven by the front and rear wheels during vehicle movement can be blocked during vehicle driving, preventing foreign objects from entering the vehicle and improving the service life of the vehicle. The filter 5 and each part are fixed by bolts 9 and nuts 10, so that the fixation is firm and the filter 5 can be replaced by disassembling the bolts 9 and nuts 10.

[0031] Refer to Figure 3 、 Figure 4 : The first crossbeam 6 includes a first inner beam 602, and first outer beams 601 are slidably arranged on both sides of the first inner beam 602. A plurality of screw holes 11 are equidistantly arranged on the surface of the first inner beam 602. Bolts 9 are threadedly sleeved on the inner walls of the plurality of screw holes 11, and nuts 10 are threadedly sleeved at the lower ends of the plurality of bolts 9;

[0032] Specifically, by dividing the first crossbeam 6 into two parts, namely the first inner beam 602 and the first outer beam 601, and the two parts are slidably connected, the overall length of the first crossbeam 6 can be adjusted by sliding the position of the first outer beam 601, achieving the purpose of adjustable length of the first crossbeam 6. The first inner beam 602 and the first outer beam 601 are fixed by bolts 9 and nuts 10, improving the stability of the first crossbeam 6 and also facilitating the disassembly and adjustment of the length of the first crossbeam 6.

[0033] Refer to Figure 5 、 Figure 6 : The second crossbeam 8 includes a second inner beam 802, and second outer beams 801 are slidably arranged on both sides of the second inner beam 802;

[0034] Specifically, by dividing the second crossbeam 8 into two parts, namely the second inner beam 802 and the second outer beam 801, and the two parts are slidably connected, the overall length of the second crossbeam 8 can be adjusted by sliding the position of the second outer beam 801, achieving the purpose of adjustable length of the second crossbeam 8.

[0035] Working principle: When the vehicle frame is impacted, it will squeeze the rubber buffer 2 inward. By squeezing the rubber buffer 2, part of the impact force will be released. While the first bumper 1 is squeezing inward, it will drive the first sliding rod 12 to move inward. The first sliding rod 12 will drive the baffle 13 to move inward. The baffle 13 will drive the second sliding rod 14 to squeeze inward. When the second sliding rod 14 squeezes out the rubber plug 16, the baffle 13 will squeeze out the buffer liquid 15 through the notch at the rear end of the storage tank 4, converting the remaining impact force into the kinetic energy of the buffer liquid 15 and releasing it, thereby improving the impact resistance of the vehicle frame;

[0036] Secondly, by dividing the first crossbeam 6 into two parts, namely the first outer beam 601 and the first inner beam 602, the position of the first outer beam 601 can be adjusted slidably. After adjusting the first outer beam 601 to a suitable position, it is fixed with bolts 9 and nuts 10, so as to achieve the purpose of adjusting the first crossbeam 6 and further achieve the purpose of adjusting the overall size of the vehicle frame. Then, filter screens 5 are respectively arranged at the front and rear ends of the vehicle frame, which can block foreign objects driven by the vehicle movement during the vehicle running, prevent foreign objects from entering the vehicle, and improve the service life of the vehicle.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
