[0031] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0032] Reference will be made below to Figures 1-4 describe the chassis 100 according to an embodiment of the present utility model. The chassis 100 can be applied to a vehicle 1000.

[0033] Combined with Figures 1-4 As shown, the chassis 100 according to the present utility model mainly includes: longitudinal beams 10, a fuel tank assembly, and a crossbeam 30.

[0034] Among them, the longitudinal beams 10 are arranged to extend in the front-rear direction and there are two of them. The two longitudinal beams 10 are arranged at intervals in the left-right direction and are respectively the first longitudinal beam 11 and the second longitudinal beam 12. The fuel tank assembly is arranged between the two longitudinal beams 10 and is adjacent to the first longitudinal beam 11. The fuel tank assembly is connected to the first longitudinal beam 11. The crossbeam 30 is arranged to extend in the left-right direction and is respectively connected to the two longitudinal beams 10. The crossbeam 30 is located above the fuel tank assembly and corresponds to the rear end of the fuel tank assembly.

[0035] Specifically, the two longitudinal beams 10 are defined as the first longitudinal beam 11 and the second longitudinal beam 12 respectively. Both the first longitudinal beam 11 and the second longitudinal beam 12 are arranged to extend in the front-rear direction, and the first longitudinal beam 11 and the second longitudinal beam 12 are arranged at intervals in the left-right direction. A crossbeam 30 can be arranged between the first longitudinal beam 11 and the second longitudinal beam 12. The two ends of the crossbeam 30 are respectively connected to the first longitudinal beam 11 and the second longitudinal beam 12. In this way, the basic framework of the chassis 100 can be formed to provide support for other components of the vehicle 1000.

[0036] It should be noted that both the first longitudinal beam 11 and the second longitudinal beam 12 are arranged to extend in the front-rear direction. The chassis 100 is provided with a plurality of crossbeams connected between the first longitudinal beam 11 and the second longitudinal beam 12. The plurality of crossbeams are arranged at intervals in the front-rear direction, so as to further improve the structural reliability of the chassis 100.

[0037] Among them, the fuel tank assembly is arranged between two longitudinal beams 10 and adjacent to the first longitudinal beam 11. The fuel tank assembly is connected to the first longitudinal beam 11. The cross beam 30 of the present application is located above the fuel tank assembly and corresponds to the rear end of the fuel tank assembly. In some embodiments, a plurality of cross beams are named in sequence in the front-to-back direction, and the cross beam 30 of the present application is the seventh cross beam. Further, the cross beam 30 of the present application can be set as a circular tube steel beam structure. The cross beam 30 is arranged on the front side of the shock absorber bracket 13, so as to increase the stiffness at the rear suspension position and improve the overall torsional stiffness of the chassis 100.

[0038] Further, at least one of a fuel tank isolation valve bracket 31, a charger bracket 32, a carbon canister bracket 33, and a wire harness bracket 34 is arranged on the cross beam 30. The fuel tank isolation valve bracket 31 is suitable for installing a fuel tank isolation valve 200, the charger bracket 32 is suitable for installing a charger 300, the carbon canister bracket 33 is suitable for installing a carbon canister 400, and the wire harness bracket 34 is suitable for installing a wire harness 500 on the chassis 100.

[0039] Specifically, considering that the cross beam 30 of the present application is located at the rear side of the cab, there are not only a variety of wire harnesses 500 in this part, but also components such as a fuel tank isolation valve 200, a charger 300, and a carbon canister 400 need to be assembled.

[0040] By arranging at least one of a fuel tank isolation valve bracket 31, a charger bracket 32, a carbon canister bracket 33, and a wire harness bracket 34 on the cross beam 30, the fuel tank isolation valve bracket 31 can be used to install the fuel tank isolation valve 200, the charger bracket 32 can be used to install the charger 300, the carbon canister bracket 33 can be used to install the carbon canister 400, and the wire harness bracket 34 can be used to install the wire harness 500 on the chassis 100. That is, the cross beam 30 of the present application can be selectively integrated with a variety of brackets, which can provide assembly functions for a variety of components and meet the layout requirements of more than 1000 components of the vehicle.

[0041] Moreover, in a specific embodiment of the present utility model, by arranging a fuel tank isolation valve bracket 31, a charger bracket 32, a carbon canister bracket 33, and a wire harness bracket 34 on the cross beam 30, and by making the fuel tank isolation valve bracket 31, the charger bracket 32, the carbon canister bracket 33, and the wire harness bracket 34 be arranged at intervals from each other, the layout of components such as the wire harness 500, the fuel tank isolation valve 200, the charger 300, and the carbon canister 400 can be made more uniform and reasonable, avoiding interference between a variety of wire harnesses 500, the fuel tank isolation valve 200, the charger 300, the carbon canister 400 and other components, and ensuring the normal operation of the vehicle 1000.

[0042] Optionally, the fuel tank isolation valve bracket 31, the charger bracket 32, the carbon canister bracket 33, and the wire harness bracket 34 can all be made of sheet metal bending parts. In this way, while ensuring the structural strength of each bracket, the addition of stamping die parts can be avoided, and the development cost can be reduced.

[0043] Thus, by providing at least one of the fuel tank isolation valve bracket 200, the charger bracket 32, the carbon canister bracket 33, and the wire harness bracket 34 on the cross beam 30, relevant components can be installed on the cross beam 30 through the corresponding brackets. In this way, not only can the corresponding components make full use of the available space on the cross beam 30, improving the space utilization rate of the chassis 100, realizing the integration of components on the cross beam 30, making the relevant components more compact, but also by adjusting the positions of the corresponding brackets on the cross beam 30, the layout of the corresponding components on the chassis 100 can be adjusted, making the layout of components on the chassis 100 more reasonable.

[0044] Combined with Figures 1-4 As shown, both the fuel tank isolation valve bracket 31 and the charger bracket 32 are provided on the front side of the cross beam 30, and the fuel tank isolation valve bracket 31 and the charger bracket 32 are spaced apart in the left-right direction.

[0045] Specifically, the fuel tank assembly is provided on the front side of the cross beam 30. The fuel tank assembly needs to be configured with a corresponding fuel tank isolation valve 200. To facilitate the connection between the fuel tank assembly and the fuel tank isolation valve 200, the fuel tank isolation valve 200 also needs to be provided on the front side of the cross beam 30. Moreover, during actual assembly, the charger 300 also needs to be provided on the front side of the cross beam 30.

[0046] By providing both the fuel tank isolation valve bracket 31 and the charger bracket 32 on the front side of the cross beam 30 and spacing them apart in the left-right direction, the distribution of the fuel tank isolation valve bracket 31 and the charger bracket 32 on the cross beam 30 can be made more reasonable, and they can respectively adapt to the corresponding assembly positions of the fuel tank isolation valve 200 and the charger 300, ensuring the normal operation of the fuel tank isolation valve 200 and the charger 300.

[0047] Combined with Figures 1-4 As shown, the chassis 100 may further include: a connecting half beam 40. The fuel tank isolation valve bracket 31 is disposed adjacent to the first longitudinal beam 11, the charger bracket 32 is disposed adjacent to the second longitudinal beam 12. The connecting half beam 40 extends in the left-right direction and its first end 41 is connected to the first longitudinal beam 11. The connecting half beam 40 is spaced apart from the front side of the cross beam 30. The fuel tank isolation valve bracket 31 is fixedly connected to the connecting half beam 40, and the second end 42 of the connecting half beam 40 is spaced apart from the charger bracket 32.

[0048] Specifically, both the fuel tank isolation valve bracket 31 and the fuel tank assembly are disposed adjacent to the first longitudinal beam 11, and the charger bracket 32 is disposed adjacent to the second longitudinal beam 12. By providing the connecting half beam 40, the connecting half beam 40 is disposed on the front side of the cross beam 30 and spaced apart from the cross beam 30, and the connecting half beam 40 is extended in the left-right direction and the first end 41 is connected to the first longitudinal beam 11. A fuel tank assembly bracket 44 can be provided on the connecting half beam 40, and the fuel tank assembly bracket 44 can be used for the assembly of the fuel tank assembly on the chassis 100.

[0049] It can be understood that the second end 42 of the connecting half beam 40 is spaced apart from the charger bracket 32. The second end 42 of the connecting half beam 40 is a free end, and the connecting half beam 40 is a cantilever beam with poor structural strength and stiffness. By fixedly connecting the fuel tank isolation valve bracket 31 to the connecting half beam 40, the cantilever length of the connecting half beam 40 can be shortened, the structural strength and stiffness of the connecting half beam 40 can be improved, thereby improving the installation stability of the fuel tank assembly on the chassis 100 and improving the reliability of the vehicle 1000.

[0050] Combined with Figures 1-4 As shown, a first heat dissipation pipeline bracket 43 is provided at the second end 42 of the connecting half beam 40. The first heat dissipation pipeline bracket 43 is spaced apart from the charger bracket 32, and the first heat dissipation pipeline bracket 43 is suitable for installing the heat dissipation pipeline 600.

[0051] Specifically, the second end 42 of the connecting half beam 40 is located at the middle position in the left-right direction of the chassis 100. The heat dissipation pipeline 600 of the chassis 100 will pass through this position during layout. By providing the first heat dissipation pipeline bracket 43 at the second end 42 of the connecting half beam 40, and the first heat dissipation pipeline bracket 43 is spaced apart from the charger bracket 32, the first heat dissipation pipeline bracket 43 can be used to install the heat dissipation pipeline 600, so that the heat dissipation pipeline 600 is fixed when passing through the second end 42, making the heat dissipation pipeline 600 more orderly on the chassis 100, and avoiding interference between the heat dissipation pipeline 600 and other components, thereby ensuring the orderly layout of the heat dissipation pipeline 600, ensuring the structural integrity of the heat dissipation pipeline 600, and further ensuring that the heat dissipation pipeline 600 can work properly.

[0052] Furthermore, combined with Figures 1-4 As shown, a second heat dissipation pipeline bracket 35 is provided at the portion of the cross beam 30 corresponding to the part between the fuel tank isolation valve bracket 31 and the charger bracket 32. The second heat dissipation pipeline bracket 35 is spaced apart from the fuel tank isolation valve bracket 31 and the charger bracket 32 respectively, and the second heat dissipation bracket is suitable for installing the heat dissipation pipeline 600.

[0053] Specifically, when arranging the heat dissipation pipeline 600, it is necessary to cross the crossbeam 30 in the front-rear direction. By arranging a second heat dissipation pipeline bracket 35 at the part of the crossbeam 30 corresponding to the fuel tank isolation valve bracket 31 and the charger bracket 32, the second heat dissipation pipeline bracket 35 is arranged at intervals from the fuel tank isolation valve bracket 31 and the charger bracket 32 respectively. In this way, the second heat dissipation pipeline bracket 35 can be used to install the heat dissipation pipeline 600, so that the heat dissipation pipeline 600 is fixed when crossing the crossbeam 30, making the heat dissipation pipeline 600 more orderly on the chassis 100, and avoiding interference between the heat dissipation pipeline 600 and other components. Thus, the orderly arrangement of the heat dissipation pipeline 600 can be ensured, the structural integrity of the heat dissipation pipeline 600 can be guaranteed, and further the normal operation of the heat dissipation pipeline 600 can be ensured.

[0054] Combined with Figures 1-4 As shown, there are multiple wire harness brackets 34. The multiple wire harness brackets 34 are arranged at intervals in the left-right direction. Some of the multiple wire harness brackets 34 are arranged on the front side of the crossbeam 30, and some of the multiple wire harness brackets 34 are arranged on the upper side of the crossbeam 30.

[0055] Specifically, there are multiple wire harnesses 500 passing through the chassis 100, and the running directions of the multiple wire harnesses 500 are also inconsistent. By arranging the multiple wire harness brackets 34 at intervals in the left-right direction, and arranging some of the multiple wire harness brackets 34 on the front side of the crossbeam 30 and some of the multiple wire harness brackets 34 on the upper side of the crossbeam 30, the distribution positions of the multiple wire harness brackets 34 on the crossbeam 30 can be optimized, so that the multiple wire harness brackets 34 can adapt to the running directions of different wire harnesses 500. On the premise of ensuring the fixation and guidance of the wire harness 500, the multiple wire harnesses 500 are made more orderly on the chassis 100, avoiding the multiple wire harnesses 500 from being redundant and disorderly, and avoiding interference between the wire harness 500 and other components. Thus, the orderly arrangement of the wire harness 500 can be ensured, the structural integrity of the wire harness 500 can be guaranteed, and further the normal operation of the wire harness 500 can be ensured.

[0056] It should be noted that the wire harness bracket 34 can be arranged not only on the crossbeam 30, but also on components such as the charger bracket 32, so as to make full use of the space and ensure the orderly arrangement of the wire harness 500.

[0057] Furthermore, in addition to arranging multiple wire harness brackets 34 on the crossbeam 30, snap installation holes can also be directly opened on the crossbeam 30. Only need to set the snap in the snap installation hole, and then make the snap clamp and fix the wire harness 500. Thus, on the premise of realizing the fixation and guidance of the wire harness 500, the structure of the crossbeam 30 can be made simpler and lighter.

[0058] Combined with Figure 1 and Figure 4As shown, the canister bracket 33 is disposed on the upper side of the cross beam 30 and adjacent to the first longitudinal beam 11. A canister auxiliary bracket 111 is provided on the first longitudinal beam 11. The canister auxiliary bracket 111 is located at the rear side of the cross beam 30 and is spaced from the cross beam 30. The canister bracket 33 and the canister auxiliary bracket 111 are jointly adapted to mount the canister 400.

[0059] Specifically, the canister 400 is disposed at the rear side of the cross beam 30 and adjacent to the first longitudinal beam 11. By disposing the canister bracket 33 on the upper side of the cross beam 30 and adjacent to the first longitudinal beam 11, and making the canister auxiliary bracket 111 located at the rear side of the cross beam 30 with the canister auxiliary bracket 111 spaced from the cross beam 30, only by connecting the canister 400 to the canister bracket 33 and the canister auxiliary bracket 111 simultaneously, the canister 400 can be mounted in the rear space of the cross beam 30. The canister bracket 33 and the canister auxiliary bracket 111 can respectively provide connection forces for the canister 400, enabling the canister 400 to receive connection forces in the front-rear direction and the left-right direction, thereby realizing the mounting of the canister 400 on the chassis 100 and improving the stability and reliability of the canister 400 on the chassis 100.

[0060] Combined Figure 1 、 Figure 3 and Figure 4 As shown, the charger bracket 32 can mainly include a bracket base 321 and a bracket body 322. The bracket base 321 is connected to the cross beam 30. The bracket body 322 is connected to the bracket base 321 and extends forward. The bracket body 322 is strip-shaped and there are two of them. The two bracket bodies 322 are spaced in the left-right direction.

[0061] Specifically, the charger bracket 32 can be made to include the bracket base 321 and the bracket body 322. During production and manufacturing, the bracket base 321 can be first connected to the cross beam 30. For example, the bracket base 321 is semi-wrapped and welded to the cross beam 30. Then, the two strip-shaped bracket bodies 322 are respectively connected to the front side of the bracket base 321, and the two bracket bodies 322 are spaced in the left-right direction, thus completing the installation of the charger bracket 32 on the cross beam 30. The two bracket bodies 322 can be connected to the charger 300 to realize the assembly function of the chassis 100 for the charger 300.

[0062] Furthermore, considering the relatively large volume of the charger 300 and the need to consider disassembling the charger 300 from the lower part of the chassis 100, the bracket body 322 and the bracket base 321 can be detachably connected. In this way, by disassembling the bracket body 322, the charger 300 connected to it can be disassembled from the lower part of the chassis 100, thereby avoiding separating the chassis 100 and the vehicle body during maintenance and improving the maintenance convenience.

[0063] Optionally, at least one first perforation may be formed on each bracket body 322, and at least one second perforation may be correspondingly provided on the bracket base 321. The first fastener 323 is passed through the first perforation and the second perforation simultaneously and fastened to achieve a detachable connection between the bracket body 322 and the bracket base 321. Among them, the first fastener 323 may be a bolt.

[0064] Combined with Figure 3 and Figure 4 As shown, a connecting plate 324 is also connected between the two bracket bodies 322. The connecting plate 324 extends in the left - right direction. A reinforcing plate 36 is also provided on the front side of the cross beam 30. The reinforcing plate 36 extends in the left - right direction. The reinforcing plate 36 is located between the two bracket bodies 322 and is connected to the connecting plate 324.

[0065] Specifically, by connecting the connecting plate 324 between the two bracket bodies 322, the connecting plate 324 is made to extend in the left - right direction. For example, the two ends of the connecting plate 324 in the left - right direction are welded to the two bracket bodies 322, which can improve the structural strength of the two bracket bodies 322 and improve the overall structural stability of the charger bracket 32.

[0066] Furthermore, the bracket base 321 is connected to the cross beam 30, and the two bracket bodies 322 are connected to the bracket base 321, that is, the two bracket bodies 322 are not directly connected to the cross beam 30, which may result in relatively low overall setting stability and durability.

[0067] By further providing a reinforcing plate 36 on the front side of the cross beam 30, making the reinforcing plate 36 extend in the left - right direction, and making the reinforcing plate 36 located between the two bracket bodies 322 and connected to the connecting plate 324, the overall structural strength and durability of the charger bracket 32 can be further improved, and the off - road performance of the charger bracket 32 as a whole can be improved.

[0068] Optionally, at least two third perforations spaced in the left - right direction may be provided on the reinforcing plate 36. The second fastener 38 is passed through the third perforations and fastened to the bracket base 321. This can increase the strength and dynamic stiffness of the charger bracket 32, improve the durable and reliable performance of the vehicle 1000 under complex working conditions, and improve the off - road performance of the vehicle 1000. Among them, the second fastener 38 may be a bolt.

[0069] Furthermore, in some embodiments of the present utility model, considering that an exhaust system is also provided below the charger 300, an exhaust pipe hook 37 may also be integrally designed on the charger bracket 32. The exhaust pipe hook 37 can be used to fix and limit the exhaust pipe of the exhaust system.

[0070] Combined with Figure 3As shown, transition plates 20 can be designed on the inner and outer sides where the cross beam 30 and the longitudinal beam 10 overlap. Specifically, the cross beam 30 and the transition plate 20 are welded, and then the transition plate 20 and the longitudinal beam 10 are welded, which can further improve the connection strength and reliability between the cross beam 30 and the longitudinal beam 10.

[0071] The vehicle 1000 according to the present utility model may mainly include: the above-mentioned chassis 100.
