Description

Technical Field

[0001] The present invention relates to the field of vehicle body modification, and in particular to a vehicle modification method and a vehicle. Background Art

[0002] The body of a traditional pickup truck is usually divided into two parts: a cockpit and a cargo box. The cockpit is used to carry passengers, and the cargo box is used to load cargo. The two are separate and connected through the frame and suspension to realize the assembly of the entire vehicle. The cockpit does not directly bear the force transmitted from the suspension, so the body of this pickup truck is called a non-load-bearing body.

[0003] The frame of this non-load-bearing body is independent, and the body relies on the independent frame for support. All derivative models based on this type of body are also derived by separately changing the body and frame. However, the independent frame causes disadvantages such as increased vehicle weight, non-compact structural layout, high chassis rigidity, and insufficient driving and handling comfort. Summary of the invention

[0004] An object of the first aspect of the present invention is to provide a method for modifying a vehicle so that the vehicle has both driving comfort and cargo carrying capacity.

[0005] A further object of the first aspect of the present invention is to provide a vehicle modification method that reduces vehicle deadweight and has a compact structural layout.

[0006] The second aspect of the present invention aims to provide a vehicle having both driving comfort and cargo carrying capacity.

[0007] According to the first aspect above, the present invention provides a method for modifying a vehicle, comprising:

[0008] Modify the rear part of the original car body;

[0009] Connecting a longitudinal beam extension beam to an end of the original longitudinal beam of the original vehicle body close to the rear of the vehicle;

[0010] Connecting a support beam to the longitudinal beam extension beam;

[0011] Wherein, the longitudinal beam extension beam is connected to the support beam to form a part of the cargo box of the vehicle.

[0012] Optionally, the modification of the rear part of the original vehicle body includes:

[0013] The original longitudinal beam and the parts welded to the side wall of the original longitudinal beam are cut.

[0014] Optionally, cutting the parts welded to the side wall of the original longitudinal beam includes:

[0015] Cutting of process supports and exhaust system hooks.

[0016] Optionally, connecting a longitudinal beam extension beam to an end of the original longitudinal beam of the original vehicle body close to the rear of the vehicle comprises:

[0017] The longitudinal beam extension beam is overlapped with the original longitudinal beam.

[0018] Optionally, the support beam comprises:

[0019] column beams, supporting cross beams, upper supporting longitudinal beams, middle supporting longitudinal beams and lower supporting longitudinal beams;

[0020] The upright beam is arranged along the vertical direction of the vehicle, the supporting cross beam is arranged along the transverse direction of the vehicle, and the upper supporting longitudinal beam, the middle supporting longitudinal beam and the lower supporting longitudinal beam are all arranged along the longitudinal direction of the vehicle.

[0021] Optionally, the wall thickness of the longitudinal beam extension beam is greater than a first preset value.

[0022] Optionally, the length of the overlapping area between the longitudinal beam extension beam and the original longitudinal beam is greater than a second preset value.

[0023] Optionally, the overlapping area between the longitudinal beam extension beam and the original longitudinal beam is welded by a preset type of welding process combination.

[0024] Optionally, after the supporting beam is connected to the longitudinal beam extension beam, the method further comprises:

[0025] The cargo box outer panel is welded or assembled on the frame formed by connecting the original vehicle body, the longitudinal beam extension beam and the support beam.

[0026] According to the above second aspect, the present invention also provides a vehicle, which is modified by adopting the above modification method for a vehicle.

[0027] The modification method for a vehicle provided by the present invention comprises modifying the rear part of the original vehicle body, connecting a longitudinal beam extension beam to one end of the original longitudinal beam of the original vehicle body close to the rear part, and connecting a support beam to the longitudinal beam extension beam. The modification of the rear part of the original vehicle body is to provide a basis for the modification of the vehicle body. After the modification of the original vehicle body meets the basis for the modification of the vehicle body, the longitudinal beam extension beam is connected to the original longitudinal beam, and then the support beam is connected to the longitudinal beam extension beam. After the longitudinal beam extension beam and the support beam are connected, a part of the cargo box of the vehicle is formed. After the vehicle is modified by the above modification method, the front part of the original vehicle body does not change, and the cargo space at the rear part is increased, so that the vehicle has both the passenger comfort of the front part of the original vehicle body and the load-bearing capacity of the rear part of the modified vehicle body.

[0028] Furthermore, the modified vehicle has the carrying capacity of the pickup truck in the prior art, but compared with the pickup truck in the prior art, the independent frame of the pickup truck is cancelled, and the cargo box and the front body are connected by the original longitudinal beam and the longitudinal beam extension beam, which reduces the vehicle's own weight and makes the vehicle's structural layout compact.

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] Figure 1 FIG1 is a flowchart of a vehicle modification method according to an embodiment of the present invention. As shown in FIG1 , the present invention provides a vehicle modification method, which generally includes:

[0040] S10: modifying the rear part of the original vehicle body 10;

[0041] S20: Connecting a longitudinal beam extension beam 20 to an end of the original longitudinal beam 11 of the original vehicle body 10 close to the rear end of the vehicle body;

[0042] S30 : Connecting the support beam 30 to the longitudinal beam extension beam 20 .

[0043] The longitudinal beam extension beam 20 is connected to the support beam 30 to form a part of the vehicle cargo box. The original vehicle body 10 can be a passenger car, SUV, MPV or other passenger vehicle body, and the performance of the front part of the modified vehicle body is similar to that of the front part of the original vehicle body 10.

[0044] The modification method for a vehicle provided in this embodiment includes modifying the rear part of the original vehicle body 10, connecting a longitudinal beam extension beam 20 to the end of the original longitudinal beam 11 of the original vehicle body 10 near the rear of the vehicle, and connecting a support beam 30 to the longitudinal beam extension beam 20. The modification of the rear part of the original vehicle body 10 is to provide a basis for the modification of the vehicle body. After the original vehicle body 10 meets the requirements for the modification of the vehicle body after modification, the longitudinal beam extension beam 20 is connected to the original longitudinal beam 11, and then the support beam 30 is connected to the longitudinal beam extension beam 20. The longitudinal beam extension beam 20 and the support beam 30 are connected to form a part of the cargo box of the vehicle. After the vehicle is modified by the above modification method, the front part of the original vehicle body 10 is not changed, and the cargo space at the rear part is increased, so that the vehicle has both the passenger comfort, controllability and quality of the front part of the original vehicle body 10, and the load-bearing capacity of the rear part of the modified vehicle body.

[0045] Furthermore, under the premise of ensuring the pickup truck's cargo carrying capacity, the modification method makes only minor changes or minor optimizations to the original chassis structure of the vehicle body 10, so that the modified vehicle can still inherit the genes of a passenger vehicle. The modified vehicle has the carrying capacity of a pickup truck in the prior art, but compared with the pickup truck in the prior art, the independent frame of the pickup truck is cancelled, and the cargo box and the front vehicle body are connected through the original longitudinal beam 11 and the longitudinal beam extension beam 20, which reduces the vehicle's own weight and makes the vehicle's structural layout compact.

[0046] Furthermore, by modifying the original vehicle body 10, that is, the existing vehicle body to form a new vehicle body, a large amount of investment in research and development and mold development is reduced compared with the method of directly developing a vehicle with both passenger and load-bearing capacity.

[0047] The length of the longitudinal beam extension beam 20 can be selected according to actual needs, and the present invention does not limit it.

[0048] Figure 2 It is a schematic diagram of cutting the original vehicle body in a method for modifying a vehicle according to an embodiment of the present invention. Figure 3 1 is a schematic diagram of modifying the original longitudinal beam according to a method for modifying a vehicle according to an embodiment of the present invention. In a preferred embodiment, modifying the rear part of the original vehicle body 10 includes:

[0049] The original longitudinal beam 11 and the parts of the side wall welded to the original longitudinal beam 11 are cut.

[0050] like Figure 2 As shown, in a specific embodiment, cutting the parts welded to the side wall of the original longitudinal beam 11 includes:

[0051] The process support 12 and the exhaust system hook 13 are cut.

[0052] like Figure 3 As shown, reference numeral 14 indicates the cutting position of the original longitudinal beam 11. Before cutting the original longitudinal beam 11, the rear panel of the original vehicle body 10 needs to be cut, and the cutting position is aligned with the two side surfaces of the original longitudinal beam 11.

[0053] Those skilled in the art should know that the cutting of the original vehicle body 10 includes all parts that affect the connection between the original longitudinal beam 11 and the longitudinal beam extension beam 20 , and is not limited to the cutting of the process bracket 12 and the exhaust system hook 13 .

[0054] Figure 4 is a front view of a rebuilt vehicle used in a vehicle rebuilding method according to an embodiment of the present invention. Figure 5 FIG. 1 is a perspective view of a vehicle modified according to a method for modifying a vehicle according to an embodiment of the present invention. Figure 4 As shown, you can also participate Figure 5 , connecting the longitudinal beam extension beam 20 to the end of the original beam close to the rear of the vehicle includes:

[0055] The longitudinal beam extension beam 20 is overlapped with the original longitudinal beam 11.

[0056] By overlapping and connecting the longitudinal beam extension beam 20 and the original longitudinal beam 11, the strength of the connection area between the two can be increased, thereby improving the overall strength of the cargo box.

[0057] Figure 6 FIG. 1 is a schematic structural diagram of a vehicle body modification method according to another embodiment of the present invention. Figure 6 As shown, you can also participate Figure 4 or Figure 5 , the support beam 30 comprises:

[0058] The column beam 33, the support cross beam 35, the upper support longitudinal beam 34, the middle support longitudinal beam 32 and the lower support longitudinal beam 31, wherein the column beam 33 is arranged along the vertical direction of the vehicle, the support cross beam 35 is arranged along the transverse direction of the vehicle, and the upper support longitudinal beam 34, the middle support longitudinal beam 32 and the lower support longitudinal beam 31 are all arranged along the longitudinal direction of the vehicle. In this way, the support beam 30 composed of the column beam 33 and multiple transverse and longitudinal beams can ensure the stability of the structure and improve the strength of the cargo box.

[0059] In a preferred embodiment, the wall thickness of the longitudinal beam extension beam 20 is greater than a first preset value. The first preset value is, for example, any value in the range of 5-20 mm. Those skilled in the art should know that the thicker the wall thickness of the longitudinal beam extension beam 20 is, the greater its strength will be, but at the same time, the weight will also increase accordingly, and the first preset value can be selected after testing to meet the strength requirements without increasing the weight of the vehicle too much.

[0060] In a more preferred embodiment, the length of the overlapped area between the longitudinal beam extension beam 20 and the original longitudinal beam 11 is greater than the second preset value. The second preset value is, for example, 2-20 cm. Those skilled in the art should know that the longer the overlapped area is, the greater the overlapped strength between the original longitudinal beam 11 and the longitudinal beam extension beam 20 is, but the weight will also increase. The second preset value can be selected after testing to meet the strength requirements without increasing the weight of the vehicle too much.

[0061] In a further embodiment, the cross-sectional shape of the longitudinal beam extension beam 20 is the same as the cross-sectional shape of the original longitudinal beam 11, and the longitudinal beam extension beam 20 can be set outside the original longitudinal beam 11, or can be passed through the inside of the original longitudinal beam 11. It is required that the distance between the longitudinal beam extension beam 20 and the original longitudinal beam 11 in the overlapped area after the longitudinal beam extension beam 20 is overlapped is less than a third preset value, so as to further increase the connection strength between the longitudinal beam extension beam 20 and the original longitudinal beam 11.

[0062] In a specific embodiment, the cross-sectional shapes of the longitudinal beam extension beam 20 and the original longitudinal beam 11 are closed shapes (eg, rectangular or a deformation of a rectangle).

[0063] In a further embodiment, the overlapped area of ​​the longitudinal beam extension beam 20 and the original longitudinal beam 11 is welded by a combination of preset welding processes, such as seam welding and plug welding, which can increase the welding strength.

[0064] Figure 7 FIG. 1 is a schematic structural diagram of a method for modifying a vehicle according to another embodiment of the present invention for modifying an original vehicle body 10. Figure 7 As shown, after the supporting beam 30 is connected to the longitudinal beam extension beam 20, the following steps are also included:

[0065] The cargo box outer panel 40 is welded or assembled on the frame formed by connecting the original vehicle body 10, the longitudinal beam extension beam 20 and the support beam 30. After welding and assembling the cargo box outer panel 40, a complete cargo box is formed.

[0066] In particular, the present invention further provides a vehicle, which is remanufactured by adopting the remanufacture method provided by any one of the above embodiments, and the vehicle generally comprises an original longitudinal beam 11, a longitudinal beam extension beam 20 and a support beam 30. The original longitudinal beam 11 is arranged along the longitudinal direction of the vehicle. The longitudinal beam extension beam 20 is arranged along the longitudinal direction of the vehicle, and the longitudinal beam extension beam 20 is connected to one end of the original longitudinal beam 11 close to the rear of the vehicle. The support beam 30 is connected to the longitudinal beam extension beam 20. The longitudinal beam extension beam 20 and the support beam 30 are connected to form a part of the cargo box of the vehicle. The vehicle has both driving comfort and cargo carrying capacity.
