[0037] A front axle 8 is provided at the front end of the vehicle frame 1, and a rear axle 9 is provided at the rear end of the vehicle frame 1. The front axle 8 and the rear axle 9 are collectively referred to as vehicle axles (also referred to as axles). The front axle 8 and the rear axle 9 are connected to the vehicle frame 1 through a suspension. Both ends of the front axle 8 and the rear axle 9 are used to mount wheels. The front half-axle is connected between the front axle 8 and the front wheels, and the rear half-axle is connected between the rear axle 9 and the rear wheels. Both the front axle 8 and the rear axle 9 can be used as drive axles to drive the vehicle to move.

[0038] The all-terrain vehicle in this embodiment is a hybrid vehicle, that is, it is driven by both an electric motor and an engine. It has the advantages of good engine power, fast response and long working time, as well as the advantages of no pollution and low noise of the power motor 2, achieving the best match between the engine 3 and the power motor 2.

[0039] In this embodiment, the front axle 8 is driven by the power motor 2, and the rear axle 9 is driven by the engine 3. The power motor 2 is arranged on the lower main beam frame 01 and is located in front of the seat cushion, that is, the power motor 2 is located on the side adjacent to the front axle 8, and the engine 3 is arranged on the lower main beam frame 102 and is located below the seat cushion, that is, the engine 3 is located between the rear axle 9 and the power motor 2.

[0040] According to the all-terrain vehicle of the embodiment of the present invention, the driving power motor 2 is placed in front and in front of the seat, and the engine 3 is arranged in the middle of the frame 1 and below the seat. The design is reasonable, and the overall weight distribution of the frame 1 is even, thereby improving the stability of the all-terrain vehicle.

[0041] In some embodiments, the connecting beam includes a first rear connecting beam 106 and a second rear connecting beam 105 located behind the engine 3, the upper end of the first rear connecting beam 106 is connected to the upper main beam frame 101, the lower end of the first rear connecting beam 106 is connected to the lower main beam frame 102, the upper end of the second rear connecting beam 105 is connected to the upper main beam frame 101, the lower end of the second rear connecting beam 105 is connected to the lower main beam frame 102, and the rear axle 9 is located between the first rear connecting beam 106 and the second rear connecting beam 105.

[0042] A support beam 107 is provided between the first rear connecting beam 106 and the second rear connecting beam 105. One end of the support beam 107 is connected to the second rear connecting beam 105, and the other end of the support beam 107 is connected to the first rear connecting beam 106. The support beam 107 is a horizontally arranged crossbeam. The support beam 107 is located above the rear axle 9. The all-terrain vehicle also includes a power battery 4, which is used to supply power to the power motor 2 to drive the front axle 8 to rotate. The power battery 4 is arranged on the support beam 107. It should be noted that there are two first rear connecting beams 106 and two second rear connecting beams 105, which are arranged at intervals along the width direction of the all-terrain vehicle.

[0043] A reinforcement 112 is provided between the upper main beam frame 101 and the first rear connecting beam 106. Specifically, there is an angle between the upper main beam frame 101 and the first rear connecting beam 106. One end of the reinforcement 112 is connected to the upper main beam frame 101, and the other end of the reinforcement 112 is connected to the first rear connecting beam 106. In this manner, the upper main beam frame 101, the first rear connecting beam 106 and the reinforcement 112 form a triangular structure, which can further enhance the overall strength of the frame 1.

[0044] The upper main beam frame 101 includes a first longitudinal beam 1011 and a second longitudinal beam 1012 extending longitudinally of the all-terrain vehicle. The all-terrain vehicle also includes a controller 5, which is used to control the various components of the all-terrain vehicle to operate in a coordinated manner. The controller 5 is arranged between the first longitudinal beam 1011 and the second longitudinal beam 1012.

[0045] In some embodiments, the power motor 2 is located in front of the engine 3 and behind the front axle 8. The all-terrain vehicle also includes a gearbox 6 located between the power motor 2 and the front axle 8. The input end of the gearbox 6 is connected to the power motor 2, and the output end of the gearbox 6 is connected to the front axle 8. The gearbox 6 is used to change the speed and torque of the power motor 2. It can fix or change the transmission ratio of the output shaft and the input shaft in gears to adapt to frequently changing driving conditions.

[0046] In some embodiments, the housing of the power motor 2 is fixedly connected to the housing of the gearbox 6, and the housing of the gearbox 6 is fixedly connected to the housing of the front axle 8. In this way, the power motor 2, the gearbox 6 and the front axle 8 are integrated, which can save space and reduce assembly difficulty.

[0047] In some embodiments, the all-terrain vehicle further includes a drive shaft 7, which is disposed along the length of the vehicle frame 1. The input end of the drive shaft 7 is connected to the engine 3, and the output end of the drive shaft 7 is connected to the rear axle 9.

[0048] The first rear connecting beam 106 is located in front of the second rear connecting beam 105, and the projections of the first rear connecting beam 106 and the drive shaft 7 on the longitudinal center symmetry plane of the all-terrain vehicle partially overlap. In other words, the projections of the first rear connecting beam 106 and the drive shaft 7 in the longitudinal direction of the all-terrain vehicle intersect. Therefore, the first rear connecting beam 106 can provide good protection for the drive shaft 7.

[0049] In some embodiments, the frame 1 also includes a second upper front connecting beam 103, a first upper front connecting beam 104 and a first connecting seat 110 located on the front side of the engine 3, the upper ends of the second upper front connecting beam 103 and the first upper front connecting beam 104 are both connected to the upper main beam frame 101, the lower end of the second upper front connecting beam 103 is connected to the first end of the first connecting seat 110, and the lower end of the first upper front connecting beam 104 is connected to the second end of the first connecting seat 110, and the power motor 2 is arranged below the first connecting seat 110.

[0050] The connection relationship between the second upper front connecting beam 103 , the first upper front connecting beam 104 and the first connecting seat 110 can be a detachable connection or a non-detachable connection.

[0052] In some embodiments, the vehicle frame 1 further includes a first connecting rod 108 and a second connecting rod 109. The upper end of the first connecting rod 108 is detachably connected to the first connecting seat 110, and the lower end of the first connecting rod 108 is detachably connected to the lower main beam frame 102. The upper end of the second connecting rod 109 is detachably connected to the first connecting seat 110, and the lower end of the second connecting rod 109 is detachably connected to the lower main beam frame 102. When the first connecting rod 108 and the second connecting rod 109 are all detached from the first connecting seat 110 and the lower main beam frame 102, an open area is formed between the first connecting seat 110 and the lower main beam frame 102, and the power motor 2 can enter the vehicle frame 1 through this open area, thereby reducing the difficulty of assembling the power motor 2 and reducing the assembly time.

[0053] With such an arrangement, after the power motor 2 is installed into the vehicle frame 1 through the open area between the first connecting seat 110 and the lower main beam frame 102, the open area is closed using the first connecting rod 108 and the second connecting rod 109, so that the vehicle frame 1 forms a complete frame structure without affecting the structural strength of the vehicle frame 1.

[0054] It should be noted that the number of connecting rods can be selected according to actual conditions and does not need to correspond one-to-one with the connecting beams, that is, there can be one or more connecting beams connected to the first connecting seat 110, and there can be one or more connecting rods connected to the connecting seat.

[0055] The vehicle frame 1 further includes a second connecting seat 111, which is disposed on the lower main beam frame 102. The lower end of the first connecting rod 108 is detachably connected to the second connecting seat 111, and the lower end of the second connecting rod 109 is detachably connected to the second connecting seat 111. With this arrangement, the second connecting seat 111 can be directly welded to the lower main beam frame 102, and a through hole or other structure can be provided in the second connecting seat 111 to achieve a detachable connection with the connecting rod, without affecting the structural strength of the lower main beam frame 102.

[0056] The projections of the first connecting rod 108 and the second connecting rod 109 on the longitudinal center symmetry plane of the all-terrain vehicle at least partially overlap with the projections of the power motor 2 on the longitudinal center symmetry plane of the all-terrain vehicle. In other words, the first connecting rod 108 and the second connecting rod 109 are located on the outside of the power motor 2, and the connection position of the first connecting rod 108 and the second connecting rod 109 with the first connecting seat 110 is not lower than the highest point of the power motor 2. Therefore, the first connecting rod 108 and the second connecting rod 109 can protect the power motor 2 and also facilitate the disassembly and assembly of the power motor 2.

[0057] The frame 1 further includes a connector 10. The first and second connector seats 110, 111 are each provided with a threaded hole. Both ends of the connecting rod are provided with a through hole. The connector 10 extends through the through hole and fits within the threaded hole to detachably connect the first and second connecting rods 109 to the first and second connector seats 110, 111, respectively. The connector 10 is preferably a screw. The threaded connection is simple and reliable, and is easy to assemble and disassemble, further reducing the difficulty of assembly.

[0058] Furthermore, a mounting plate 11 is provided on the first connecting rod 108 and the second connecting rod 109. The mounting plate 11 is located on the side of the connecting rod adjacent to the inner side of the frame 1, and a mounting hole is provided on the mounting plate 11. The mounting plate 11 is used to connect with the components in the frame 1 to fix the components and prevent them from moving.
