[0035] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0036] The following refers to Figures 1 - 6 Describe the chassis according to the embodiment of the first aspect of the present utility model.

[0037] As Figures 1 - 3 shown, the chassis 100 according to the embodiment of the first aspect of the present utility model includes: a battery pack 10, a brake medium pipe 20, a fuel pipe 30 and an air spring air pipe 40.

[0038] Specifically, the brake medium pipe 20 includes a first pipe portion 21, the fuel pipe 30 includes a second pipe portion 31, and the air spring air pipe 40 includes a third pipe portion 41. The first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 all extend along the front-rear direction of the vehicle, and the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are all located between the front and rear end faces of the battery pack 10. The first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are arranged on the same side of the battery pack 10 in the left-right direction of the vehicle and are connected by an integrated part 50.

[0039] That is to say, the first pipe portion 21 is the pipe of the brake medium pipe 20 between the front and rear end faces of the battery pack 10, the second pipe portion 31 is the pipe of the fuel pipe 30 between the front and rear end faces of the battery pack 10, and the third pipe portion 41 is the pipe of the air spring air pipe 40 between the front and rear end faces of the battery pack 10.

[0040] Among them, the fuel pipe 30 is connected between the fuel tank and the engine. The fuel can be fuel oil, natural gas, or other combustion media that can be used for the engine. The brake medium pipe 20 is connected between the brake control unit 60 and the wheel brake device. The brake medium can be oil for transmitting brake pressure, or the brake medium can also be gas for transmitting brake pressure. The air spring air pipe 40 is connected between the air spring air pump 70 and the air spring actuating unit.

[0041] It can be understood that by arranging the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 on the same side of the battery pack 10 in the left-right direction and connecting the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 through the integrated part 50, the distribution of the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 can be made more concentrated. Compared with the case where the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are arranged on both sides of the battery pack 10, the space occupied by the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 in the left-right direction of the vehicle can be reduced, thereby improving the space utilization rate on the chassis 100 and enabling more space on the chassis 100 for arranging the battery pack 10. It should be noted that the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 can be between the upper and lower end faces of the battery pack 10 in the up-down direction, or the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 can also extend beyond the upper and lower end faces of the battery pack 10 in the up-down direction.

[0042] At the same time, after the integrated part 50 connects the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41, the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 can be connected to the chassis 100 together. In this way, the use of connecting parts such as pipe clamps in the assembly process can be reduced, thereby further improving the space utilization rate on the chassis 100, and the assembly process can be simplified and the production cost can be reduced.

[0043] The chassis 100 according to the first aspect embodiment of the present utility model connects the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 through the integrated part 50. On the one hand, the space utilization rate on the chassis 100 can be improved, thereby increasing the layout space of the battery pack 10. On the other hand, the assembly process can be simplified and the assembly difficulty can be reduced.

[0044] In some embodiments of the present utility model, as Figures 4 - 6 shown, at least two of the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are stacked in the up-down direction. That is to say, two of the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are stacked in the up-down direction, or it can also be that the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are all stacked in the up-down direction. Thus, the space occupied by the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 in the up-down direction can be reduced, thereby further improving the space utilization rate on the chassis 100.

[0045] Among them, for those skilled in the art, it can be understood that there are two brake medium pipes 20, two fuel pipes 30, and two air spring air pipes 40, that is, the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are all two. In this way, as Figures 4 - 6 shown, when arranging the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41, the six pipelines can be divided into two layers in the up-down direction, with three pipelines in each layer, or the six pipelines can be divided into three layers in the up-down direction, with two pipelines in each layer, or the six pipelines can be stacked in the up-down direction. The above is only for illustrative purposes, and the pipeline distribution can be adjusted according to the design requirements in actual arrangement.

[0046] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, the chassis 100 further includes: a brake control unit 60. One end of the brake medium pipe 20 is connected to the brake control unit 60, and the first pipe portion 21 and the brake control unit 60 are arranged on the same side of the battery pack 10. Thus, the length of the brake medium pipe 20 can be reduced. During the production process, the production cost and production difficulty can be reduced, and during the product design process, the product design difficulty can be reduced. Among them, one end of the brake medium pipe 20 is connected to the brake control unit 60, and the other end of the brake medium pipe 20 is connected to the wheel brake device.

[0047] In some embodiments of the present utility model, as Figure 2 and Figure 3As shown, the chassis 100 further includes: a brake control unit 60. One end of the brake medium pipe 20 is connected to the brake control unit 60. The first pipe portion 21 and the brake control unit 60 are respectively disposed on the left and right sides of the battery pack 10. Among them, one end of the brake medium pipe 20 is connected to the brake control unit 60, and the other end of the brake medium pipe 20 is connected to the wheel brake device. During the product design process, the relative positions of the first pipe portion 21 and the brake control unit 60 can be adjusted according to the layout space requirements, so as to meet more product design needs.

[0048] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the chassis 100 further includes: an air spring air pump 70. One end of the air spring air pipe 40 is connected to the air spring air pump 70. The third pipe portion 41 and the air spring air pump 70 are disposed on the same side of the battery pack 10. Thereby, the length of the air spring air pipe 40 can be reduced. During the production process, the production cost and production difficulty can be reduced. During the product design process, the product design difficulty can be reduced. Among them, the air spring air pipe 40 is connected between the air spring air pump 70 and the air spring actuator unit. The chassis 100 further includes a brake control unit 60. The brake control unit 60 can be on the same side of the battery pack 10 as the first pipe portion 21 and the third pipe portion 41, or the brake control unit 60 can be on different sides of the battery pack 10 from the first pipe portion 21 and the third pipe portion 41. During the product design process, the relative positions of the air spring air pump 70, the brake control unit 60, and the first pipe portion 21 and the third pipe portion 41 can be adjusted according to the layout space requirements, so as to meet more product design needs.

[0049] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the chassis 100 further includes: an air spring air pump 70. One end of the air spring air pipe 40 is connected to the air spring air pump 70. The third pipe portion 41 and the air spring air pump 70 are respectively disposed on the left and right sides of the battery pack 10. Among them, the air spring air pipe 40 is connected between the air spring air pump 70 and the air spring actuator unit. The chassis 100 further includes a brake control unit 60. The brake control unit 60 can be on the same side of the battery pack 10 as the first pipe portion 21 and the third pipe portion 41, or the brake control unit 60 can be on different sides of the battery pack 10 from the first pipe portion 21 and the third pipe portion 41. During the product design process, the relative positions of the air spring air pump 70, the brake control unit 60, and the first pipe portion 21 and the third pipe portion 41 can be adjusted according to the layout space requirements, so as to meet more product design needs.

[0050] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, there are multiple integrated parts 50. For example, the number of integrated parts 50 can be two, three, four, five, or ten. The multiple integrated parts 50 are arranged at intervals in the front-rear direction of the vehicle. Thus, after the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are connected, they can be more stable. And compared with using one integrated part 50 that penetrates the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41, the use of materials can be reduced, and the production cost can be further reduced.

[0051] In some embodiments of the present utility model, as Figures 1 - 3 shown, the chassis 100 further includes: an exhaust pipe 80. The exhaust pipe 80 includes a fourth pipe portion 81 extending in the front-rear direction of the vehicle. The fourth pipe portion 81 is provided on one side of the battery pack 10 in the left-right direction, and the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are provided on the other side of the battery pack 10 in the left-right direction.

[0052] Thus, the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 can be spaced apart from the battery pack 10. During the operation of the vehicle, the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 will not be damaged by the heat of the exhaust pipe 80, thereby improving the reliability during the operation of the vehicle.

[0053] At the same time, compared with the situation where part or all of the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 and the fourth pipe portion 81 of the exhaust pipe 80 are on the same side of the battery pack 10, during the production and product design processes, the heat insulation materials wrapped outside the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 to reduce the heat damage of the exhaust pipe 80 can be omitted, thereby further reducing the production cost and the difficulty of product design.

[0054] Preferably, as Figure 2 and Figure 3 shown, the first pipe portion 21 and the brake control unit 60 are provided on the same side of the battery pack 10 in the left-right direction, and the brake control unit 60 is located on the front side of the battery pack 10. The steering wheel of the vehicle and the brake control unit 60 are provided on different sides of the vehicle in the left-right direction. That is, when the steering wheel of the vehicle is provided on the left side of the vehicle, the brake control unit 60 and the first pipe portion 21 are provided on the right side of the battery pack 10; when the steering wheel of the vehicle is provided on the right side of the vehicle, the brake control unit 60 and the first pipe portion 21 are provided on the left side of the battery pack 10.

[0055] It can be understood that the connection between the steering wheel of the vehicle and the adjustment wheel through the steering gear needs to occupy a part of the layout space. At the same time, the connection between the brake control unit 60 and each wheel through the brake-related components also needs to occupy a part of the layout space. The steering wheel of the vehicle and the brake control unit 60 are provided on different sides of the vehicle in the left-right direction, which can reduce the interference between the connecting components, thereby reducing the difficulty of product design and production.

[0056] In some embodiments of the present utility model, as Figure 1 shown, the chassis 100 further includes a heat insulation plate 82, the heat insulation plate 82 covers the exhaust pipe 80, and the heat insulation plate 82 is disposed between the exhaust pipe 80 and the battery pack 10. By providing the heat insulation plate 82, the heat insulation plate 82 can block between the exhaust pipe 80 and the battery pack 10, reducing the heat conducted from the exhaust pipe 80 to the battery pack 10, thereby further improving the reliability during the operation of the battery pack 10. Among them, the chassis 100 further includes a body sill beam 90, the body sill beam 90 is disposed on the left and right sides of the battery pack 10, the first pipe portion 21, the second pipe portion 31, and the third pipe portion 41 are disposed between the body sill beam 90 and the battery pack 10, and the heat insulation plate 82 is disposed between the body sill beam 90 and the battery pack 10.
