[0015] In some embodiments, a connecting plate is provided at the first end of the guide rail, and the connecting plate is detachably connected to the guide rail groove at the insertion port of the guide rail groove.

[0016] In this embodiment, a connecting plate is provided on the guide rail, which is detachably connected to the guide rail groove at the insertion point. This effectively secures the battery compartment to the end frame, improving vehicle safety. Simultaneously, it facilitates external operation and disassembly of the battery compartment, enhancing the performance of battery pack replacement and maintenance.

[0017] In some embodiments, the end frame includes a front frame and a rear frame. The battery compartment is connected to both the front and rear frames via guide structures, enabling the battery compartment to be quickly installed or removed relative to the vehicle in a second direction.

[0018] In some embodiments, a motor mounting bracket is also provided on the frame longitudinal beam. By providing the motor mounting bracket, the drive motor can be mounted on the frame longitudinal beam and supported by the frame longitudinal beam, further improving the compactness of the chassis and reducing the number of parts.

[0039] In existing vehicles, the battery compartment is located at the bottom. Research has found that existing vehicles have a complete chassis structure, including crossbeams, frame longitudinal beams, and floor. Installing the battery compartment onto the chassis results in numerous parts, a complex structure, increased weight, and difficulties in replacement and maintenance. Furthermore, the assembly gap between the battery compartment and the vehicle chassis affects space utilization, thus impacting the total battery capacity of the vehicle.

[0040] To address the aforementioned technical problems, this application proposes a vehicle chassis structure. Figure 1 This is a schematic diagram of the chassis 100 structure of a vehicle provided in some embodiments of this application.

[0041] like Figure 1As shown, the vehicle chassis 100 includes an end frame 10 and a battery compartment 20, wherein the end frame 10 is used to mount the suspension; and the battery compartment 20 is used to house the battery. The end frame 10 and the battery compartment 20 are connected at their ends in a first direction X via a guide structure 200, where the first direction X is the vehicle's travel direction. The guide structure 200 is configured to allow the battery compartment 20 to be mounted or detached relative to the end frame 10 along a second direction Y, where the second direction Y is perpendicular to the first direction X.

[0042] In some embodiments, a suspension, also known as a ride height, is an assembly of mechanisms connecting the wheels to the vehicle body, typically including springs, shock absorbers, control arms, and other accessories. The vehicle body is supported on the wheels by the suspension, which controls wheel movement to enable the vehicle to travel smoothly.

[0043] In some embodiments, the end frame 10 is used to mount vehicle components such as suspension and drive motor. For a four-wheeled vehicle, the end frame 10 may include a front frame 30 and a rear frame 40, the front frame 30 being used to mount two front wheels and their suspension, and the rear frame 40 being used to mount two rear wheels and their suspension.

[0044] In some embodiments, the battery compartment 20 is used to house the battery and power the vehicle. In some embodiments, the end of the battery compartment 20 in the first direction X can be a second crossbeam 21, such as... Figure 1 As shown in the image.

[0045] In some embodiments, the guide structure 200 typically includes two relatively movable components, such as a movable component and a fixed component, which cooperate to allow the movable component to move relative to the fixed component in a predetermined direction. The movement can include moving, rolling, sliding, rotating, etc. In the embodiments of this application, the movable component is mounted on the battery compartment 20 and moves with the battery compartment 20, while the fixed component is mounted on the end frame 10.

[0046] In some embodiments, the first direction X is the vehicle's direction of travel, including forward and backward directions.

[0047] In some embodiments, the second direction Y is perpendicular to the first direction X, and the second direction Y can be the lateral direction of the vehicle.

[0048] In the above embodiments, by connecting the battery compartment 20 to the end frame 10 via the guide structure 200, the battery compartment 20 can be installed or removed relative to the end frame 10 along the second direction Y, improving the maintainability and replaceability of the battery compartment 20. Furthermore, the direct connection between the battery compartment 20 and the end frame 10 eliminates the need for crossbeams and longitudinal beams in the original chassis cab area, significantly reducing the number of vehicle parts, improving chassis space utilization, and allowing the battery compartment 20 to carry more batteries, further enhancing the vehicle's range.

A set of suspension components is mounted on each longitudinal beam 11 and shock absorber tower 12. Directly mounting the suspension components on the longitudinal beams 11 and shock absorber towers 12 eliminates the need for a subframe and other suspension mounting structures, significantly reducing the number of parts in the end frame 10 and increasing its integration. The two longitudinal beams 11 are mounted on both sides of a first crossbeam 14, together forming the end frame 10, making its structure compact and reducing the number of parts.

[0054] In some embodiments, the end of the battery compartment 20 in the first direction X is provided with a second crossbeam 21, and the guide structure 200 is disposed between the first crossbeam 14 and the second crossbeam 21.

In this embodiment, the guide structure 200 consists of a guide rail 140 and a guide rail groove 210, respectively disposed on the first crossbeam 14 and the second crossbeam 21, facilitating quick assembly and disassembly of the battery compartment 20 and the end frame 10.

[0057] In some embodiments, a motor mounting bracket 13 is also provided on the frame longitudinal beam 11. By providing the motor mounting bracket 13, the drive motor can be mounted on the frame longitudinal beam 11 and supported by the frame longitudinal beam 11, further improving the compactness of the chassis 100 and reducing the number of parts.

[0058] like Figure 2 In the embodiment shown, the fixed component of the guide structure 200 is a guide rail 140, which is formed by the first crossbeam 14, or the guide rail 140 is an independent component mounted on the first crossbeam 14. The corresponding movable component is a guide rail groove 210, which can be disposed on the second crossbeam 21, or integrally formed by the second crossbeam 21.

[0059] In other embodiments, the fixing component of the guide structure 200 can be a guide rail groove 210, which is disposed on the first crossbeam 14 or integrally formed with the first crossbeam 14. The corresponding movable component is a guide rail 140, which can be disposed on the second crossbeam 21 or integrally formed with the second crossbeam 21.

[0060] Figure 3This is a schematic diagram of the structure of a guide rail 140 of a vehicle chassis 100 provided in some embodiments of this application.

The width of the first connecting portion 1403 in the third direction Z is smaller than the width of the main body portion 1401 in the third direction Z. The third direction Z is perpendicular to the first direction X and the second direction Y. The first connecting portion 1403 is connected to the end frame 10, and the main body portion 1401 is located on the side of the first connecting portion 1403 away from the end frame 10. The main body portion 1401 and the first connecting portion 1403 can be integrally formed, or manufactured separately and then connected together. In the second direction Y, the guide rail 140 includes an insertion end for cooperating with a movable part of the guide structure 200, and a tail end opposite to the insertion end. In some embodiments, at the tail end of the guide rail 140, a connecting plate 1402 extending along the first direction X is provided on the side of the main body 1401 away from the connecting portion. The connecting plate 1402 is used to detachably connect with the movable component, thereby realizing the detachable connection between the guide rail 140 and the guide rail groove 210.
