DETAILED DESCRIPTION

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] Unless otherwise specified, directional words such as "upper, lower, left, right" are defined according to the directions indicated in the corresponding drawings, while "inner" and "outer" refer to the inner and outer contours of the corresponding components themselves. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another, and do not have order and importance.

[0029] like Figures 1 to 3 As shown, the present disclosure exemplarily provides a vehicle chassis, which is particularly suitable for new energy heavy-duty trucks equipped with a large number of electrical appliances. Specifically, the vehicle chassis includes a main longitudinal beam 4, a first frame 1, a second frame 2 and a third frame 3. Among them, the main longitudinal beam 4 includes two arranged at intervals along the vehicle width direction. That is, the chassis provided by the present disclosure directly utilizes part of the main longitudinal beam 4 of the vehicle to bear torque and longitudinal loads. The main longitudinal beam 4 extends along the front and rear direction of the vehicle length, and the two main longitudinal beams 4 are arranged at intervals in the left and right directions of the vehicle width. The first frame 1 is arranged on the top of the main longitudinal beam 4, specifically, it spans across the two main longitudinal beams 4, and is used to install a high-voltage distribution box and an all-in-one controller. The all-in-one controller here can be selected according to actual needs, for example, a three-in-one or a four-in-one or other types of controllers.

[0030] The second frame 2 is used to install the air compressor, and is arranged between the two main longitudinal beams 4 and connected to the main longitudinal beams 4 respectively; the third frame 3 is used to install the steering pump and the air conditioning pump, and is arranged between the two main longitudinal beams 4 and connected to the main longitudinal beams 4 respectively. Among them: the second frame 2 and the third frame 3 are arranged at intervals in the vehicle length direction, and the second frame 2 and the third frame 3 are both located at the bottom of the first frame 1. The mounting frame structure can be installed on the frame under the cab. Figure 2As shown, a U-shaped or R-shaped frame structure for installing electrical appliances is formed. This frame structure can simultaneously utilize the main longitudinal beam 4 of the vehicle and the cross beam inside the frame structure to bear the longitudinal load. In more detail, the first frame 1, the second frame 2 and the third frame 3 are all installed on the main longitudinal beam 4. Since the main longitudinal beam 4 itself has a high structural strength, it is beneficial to transmit and disperse the torque and longitudinal load from the first frame 1, the second frame 2 and the third frame 3. At the same time, the first frame 1, the second frame 2 and the third frame 3 are transversely arranged on the two main longitudinal beams 4, which is equivalent to arranging multiple cross beams on the two main longitudinal beams 4, which has the effect of strengthening the strength of the frame structure. That is, this criss-crossing beam structure is more conducive to bearing torque and load.

[0031] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the vehicle chassis provided by the present disclosure forms a U-shaped or R-shaped frame structure for installing electrical appliances by using the first frame body 1 set on the top of the main longitudinal beam 4 and the second frame body 2 and the third frame body 3 set between the two main longitudinal beams 4. This frame structure can simultaneously use the main longitudinal beams 4 of the vehicle and the crossbeams inside the frame structure to bear torque and longitudinal loads, avoiding deformation of the frame structure during driving, which is conducive to ensuring driving safety. In addition, the frame structure allows the electrical appliances to be arranged between the two main longitudinal beams, thereby making full use of the space between the two main longitudinal beams 4, which is conducive to further optimizing the spatial layout of the entire vehicle.

A plurality of first mounting holes 111 are arranged at intervals along the extension direction of the first longitudinal beam 11, and can be connected to the high-strength main longitudinal beam 4 through a screw member, and have the function of left and right installation limit, ensuring the installation strength of the electrical appliance during rapid acceleration or rapid deceleration, and more installation holes can disperse stress concentration, reduce the situation of abnormal sound and looseness, and ensure that the structural frame has higher installation stability and installation strength.

[0033] The first mounting frame 101 can be constructed as a cubic frame, including multiple vertical beams 13 and multiple second longitudinal beams 14, wherein two vertical beams 13 are arranged at intervals along the vehicle length direction on each first longitudinal beam 11, the two vertical beams 13 on the same side are connected by the second longitudinal beam 14, and the two second longitudinal beams 14 on both sides are connected by the installation cross beam 15, and two installation cross beams 15 are arranged at intervals along the vehicle length direction. This cubic frame can provide a relatively sufficient installation space for the high-voltage distribution box, and can also provide good torsion resistance and load.

That is, the second mounting frame 102 is formed as a rectangular frame, which also has the function of providing good torsion resistance and load. In addition, the first frame body 1 composed of the first mounting frame 102 and the second mounting frame 102 is a truss structure as a whole, which can provide good torsion resistance and load on the one hand, and is conducive to the layout of the line on the other hand, so as to meet the compact design.

The first vertical plate 22 is connected to the main longitudinal beam 4 to transmit the torque to the main longitudinal beam 4. And the first vertical plate 22 fits the inner wall surface of the main longitudinal beam 4 to increase the contact area, thereby increasing the reliability of the connection between the two. Optionally, a through hole 212 is provided on the first transverse plate 21 and / or the first vertical plate 22.

The first reinforcing plate 23 may be integrally formed on the first vertical plate 22 by welding or the like to further improve the structural strength, and the triangular reinforcing structure can also provide better support than other shapes.

[0037] like Figure 3 As shown, in some embodiments, similar to the second frame 2, the third frame 3 may include a second transverse plate 31 extending in the vehicle width direction and a second vertical plate 32 arranged at both ends of the second transverse plate 31, the second transverse plate 31 is provided with a plurality of fourth mounting holes 311 for mounting a steering pump and a fifth mounting hole 312 for mounting an air conditioning pump along the extension direction, and the second vertical plate 32 is suitable for fitting the inner wall surface of the main longitudinal beam 4 and is provided with a sixth mounting hole 321 for cooperating with the main longitudinal beam 4 to mount the third frame 3 on the main longitudinal beam 4.

Specifically, the second transverse plate 31 may be configured as a strip and is shown in the figure as having two second transverse plates 31 arranged at intervals to improve the mounting strength. The second vertical plate 32 is connected to the main longitudinal beam 4 to transmit the torque to the main longitudinal beam 4. Furthermore, the second vertical plate 32 is fitted with the inner wall surface of the main longitudinal beam 4 to increase the contact area, thereby increasing the reliability of the connection between the two.
