For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] With the development of new energy technology, new energy vehicles are being used more and more widely. The frame of a new energy vehicle generally includes a front section component and a rear section component, wherein the front section component includes two front beams 210 and the rear section component includes two rear beams.

[0037] However, in the related art, the distances between the two front beams and the two rear beams are consistent, and the distance between the rear beams needs to be set larger due to factors such as the wheelbase, so the distance between the front beams is also set larger. In addition, since the side walls of the front beams are also used to install other automobile components such as the steering structure, and the steering structure and other automobile components are located near the center line of the frame, the position of the front beam is not convenient for installing other automobile components such as the steering structure.

[0038] Based on the above considerations, in order to solve the problems in the related art, a frame and a vehicle are proposed.

[0039] Please refer to Figures 1 to 5 As shown, Figure 1 is a structural schematic diagram of a frame provided in an embodiment of the present application, Figure 2 This application Figure 1 The enlarged schematic diagram of the N position in the figure.

[0043] The number of the front beams 210 may be more than two, and may be two.

[0044] The number of rear beams may be more than two, and may be optionally two.

[0045] In the vehicle frame provided in the embodiment of the present application, since other automobile components such as the steering structure are generally located near the center line of the frame, and other automobile components such as the steering structure are installed on the side wall of the front beam 210, by setting the minimum vertical distance M1 between adjacent front beams 210 to be smaller than the minimum vertical distance M2 between adjacent rear beams 110, the front section assembly 200 is set close to the center line of the frame, and the position of the front section assembly 200 can be adjusted to a position that is more in line with the installation position of other automobile components such as the steering structure, thereby facilitating the installation of other automobile components such as the steering structure, and there is no need to adjust the spacing between the rear beams 110.
