Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frames, in particular to a multi-link vehicle frame for supporting a comfortable passenger version pickup truck. Background Art

[0002] With the development of society, the application of vehicle frames is becoming more and more extensive. A vehicle frame is a framework structure straddling the front and rear axles of an automobile, commonly known as the main beam. It is the base of the automobile, generally composed of two longitudinal beams and several cross beams, and is supported on the wheels via suspension devices, the front axle, and the rear axle. The vehicle frame must have sufficient strength and stiffness to withstand the load of the automobile and the impact transmitted from the wheels. The function of the vehicle frame is to support and connect the various assemblies of the automobile, keep the various assemblies in the correct relative positions, and bear various loads inside and outside the automobile;

[0003] The existing Chinese patent document CN201521107293.X discloses an extended pickup truck frame structure. A first cross beam, a second cross beam, a third cross beam, a fourth cross beam, a fifth cross beam, a sixth cross beam, and a seventh cross beam are provided between two longitudinal beams. A fuel tank bracket is arranged on the longitudinal beam between the fifth cross beam and the sixth cross beam. An outer longitudinal beam reinforcing plate is connected to the outer side of the longitudinal beam between the corresponding positions of the fourth cross beam and the fuel tank bracket; an inner rear longitudinal beam reinforcing plate is covered and connected to the inner side of the longitudinal beam between the corresponding positions of the fourth cross beam and the fuel tank bracket, and the width of the inner rear longitudinal beam reinforcing plate is uniform. In the extended pickup truck frame structure of the utility model, a whole outer longitudinal beam reinforcing plate and an inner longitudinal beam reinforcing plate are added to the longitudinal beam between the fourth cross beam and the sixth cross beam. The outer longitudinal beam reinforcing plate has the characteristics of being close to the fourth cross beam and the sixth cross beam on both sides. In addition to the position characteristics, the inner longitudinal beam reinforcing plate also has the characteristic of equal width, changing the previous characteristic of being spliced and connected by multiple reinforcing plates with different shapes.

[0004] However, there are certain defects in the use of the above patent. During the frontal collision of a general whole vehicle, the energy absorption capacity of the front and rear bumpers is very limited and cannot achieve the effect of absorbing more energy;

[0005] Therefore, a multi-link vehicle frame for supporting a comfortable passenger version pickup truck is proposed here to solve the above problems. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a multi-link vehicle frame for supporting a comfortable passenger version pickup truck.

Specific embodiments

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features to form new embodiments.

[0025] The following further describes the present utility model with reference to the accompanying drawings.

[0026] As Figures 1 to 6 shown, a multi-link frame for a comfortable passenger version pickup truck includes longitudinal beams 3 and cross beams. The cross beams include a front cross beam 5 and a rear cross beam 4. There are two longitudinal beams 3, which are arranged in parallel. The front cross beam 5 and the rear cross beam 4 are respectively fixed to the front and rear ends of the longitudinal beams 3. Energy absorption devices 2 are respectively arranged on the outer sides of the front cross beam 5 and the rear cross beam 4. The energy absorption device 2 includes an energy absorption beam, an energy absorption block 23 and a connecting block 21. The energy absorption beam includes a front energy absorption beam 1 and a rear energy absorption beam 13;

[0027] One end of the connecting block 21 is fixed to the outer side wall of the cross beam. A cavity 24 is arranged inside the energy absorption block 23. A slider 22 is arranged inside the cavity 24. A plurality of springs 25 are arranged between the right side of the slider 22 and the cavity 24. The left side of the slider 22 is fixedly connected to the connecting block 21. The right side of the energy absorption block 23 is fixedly connected to the inner side wall of the energy absorption beam.

[0028] A limiting device is arranged on the inner side wall of the rear energy absorption beam 13. The limiting device includes a limiting rod 11 and a limiting beam 10;

[0029] The limiting beam 10 is fixed between the longitudinal beams 3. One end of the limiting rod 11 is fixed on the inner side wall of the rear energy-absorbing beam 13, and the other end penetrates through the rear cross beam 4 and extends to the right side of the limiting beam 10. The limiting beam 10 is provided with a limiting hole 101, and a limiting block 102 is arranged on the limiting hole 101. A convex block 12 is arranged at the end of the limiting rod 11. The diameter of the convex block 12 is the same as that of the limiting hole 101, but the aperture on the limiting block 102 is slightly smaller than that of the convex block 12. The limiting block 102 is made of high-strength rubber. When impacted, the convex block 12 can be stuck into the inside of the limiting block 102 and restricted by the limiting block 102, so as to prevent the spring 25 from releasing energy.

[0030] A guard plate 9 is further arranged at the lower end of the longitudinal beam 3. The guard plate 9 is fixed at the lower end of the longitudinal beam 3. One end of the guard plate 9 is fixed at the lower end of the front cross beam 5 through a connecting steel pipe 91, and the other end is fixed at the lower end of the middle cross beam 8. The guard plate 9 can prevent the vehicle from hitting stones during driving, protect internal components such as pipelines from being damaged, and improve the protection ability of the device.

[0031] A support beam 7 and a middle cross beam 8 are further arranged between the longitudinal beams 3. The support beam 7 and the middle cross beam 8 are fixedly welded to the longitudinal beams 3. The support beam 7 and the middle cross beam 8 increase the strength between the longitudinal beams 3 and improve the impact resistance of the vehicle frame.

[0032] A transmission mounting beam 6 is further arranged between the longitudinal beams 3. The transmission mounting beam 6 is fixed at a position between the longitudinal beams 3 close to the front cross beam 5. The transmission mounting beam 6 can place the transmission and improve the load-bearing capacity of the vehicle frame.

[0033] The working principle of the present utility model is as follows: When a collision occurs, the energy-absorbing beam receives an impact and transmits the impact force to the energy-absorbing device 2. The energy-absorbing block 23 on the energy-absorbing device 2 moves inward, and the spring 25 inside the energy-absorbing block 23 absorbs a part of the impact force to buffer the impact on the front and rear ends of the vehicle frame.

[0034] Furthermore, the space at the rear of the vehicle frame of the pickup truck is large and there are few components. To prevent secondary injuries caused by the release of energy after the spring 25 inside the energy-absorbing device 2 absorbs energy, a limiting device is also provided at the rear of the vehicle frame. The limiting rod 11 on the limiting device moves inward together with the rear energy-absorbing beam 13. Then, the convex block 12 at the end of the limiting rod 11 passes through the limiting hole 101 and is stuck into the limiting beam 10. The limiting block 102 on the limiting hole 101 is made of rubber and can hold the convex block 12 to limit it, thereby preventing the spring 25 from releasing energy.

[0035] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present utility model fall within the protection scope required by the present utility model.
