Specifically, the contour of the outer surface of the first protrusion is substantially identical to the contour of the inner surface of the first limiting hole, so that the outer surface of the first protrusion is substantially attached to the inner surface of the first limiting hole, and the first limiting hole is in surface contact with the first limiting portion 1632. In this embodiment, the first protrusion may be a cylinder, and the first position-limiting hole is sleeved on the cylinder, so that the first position-limiting hole and the cylinder form a surface contact.

Specifically, the fifth mounting portion 1637 is further provided with a fifth mounting hole 1639, and the fifth mounting hole 1639 is used for connecting parts of the all-terrain vehicle 100, so that the fifth mounting hole 1639 and the third limiting portion 1638 fix the parts of the all-terrain vehicle 100 at the same time, and the mounting stability of the all-terrain vehicle 100 is further improved. In this embodiment, the fifth mounting hole 1639 may also be used to connect the fifth mounting hole 1639 and the frame 11, that is, the fifth mounting hole 1639 may be used as a mounting hole for a component of the all-terrain vehicle 100 and a connection hole for connecting the frame 11, so as to achieve integration of multiple mounting points.

In the present embodiment, the electrical component 18 is provided with a sixth mounting hole 181 and a second stopper hole 182. The sixth mounting hole 181 and the fifth mounting hole 1639 may be connected by bolts, welding, or the like, thereby connecting the electrical component 18 and the third mounting bracket 163. Specifically, the second limiting hole 182 is sleeved on the third limiting portion 1638, that is, the second limiting hole 182 is sleeved on the second protrusion, so that the second limiting hole 182 and the third limiting portion 1638 are fixed, and the third limiting portion 1638 fixes and limits the electrical component 18. Specifically, the second protrusion may be a hemisphere, the cross section of the second limiting hole 182 is substantially circular, and the diameter of the cross section of the second limiting hole 182 is substantially the same as the diameter of the second protrusion, so that the second limiting hole 182 and the second protrusion form a line contact, and the second protrusion and the second limiting hole 182 are more stably sleeved. In this embodiment, the second protrusion may have other shapes, and it is only necessary that the second protrusion and the second stopper hole 182 form a line contact.

It is understood that the third position-limiting portion 1638 may also be a second protrusion, the second protrusion includes at least a third plane, the component of the atv 100 includes at least an edge, and the third plane of the second protrusion abuts against the edge of the component of the atv 100, so that the component of the atv 100 and the third position-limiting portion 1638 form a line contact, thereby facilitating the position limitation of the component of the atv 100 by the second position-limiting portion 1635. Specifically, the edge of the component of the all-terrain vehicle 100 may be one edge of the component of the all-terrain vehicle 100, the joint between the third plane and the fifth mounting portion 1637 is the first abutting position, and the edge of the component of the all-terrain vehicle 100 abuts against the first abutting position, so that the edge of the component of the all-terrain vehicle 100 abuts against the third plane of the second bump, and the edge of the component of the all-terrain vehicle 100 forms a line contact with the third limiting portion 1638.

As shown in fig. 15 and 16, mount assembly 16 further includes, as one implementation, a sixth mount 169. Sixth mounting bracket 169 is disposed at least partially on frame 11 and drive assembly 26 is disposed at least partially on frame 11 via sixth mounting bracket 169.

The rear axle bracket 1691 is provided with a second coupling hole 1691a, and the power supply bracket 1692 is provided with a third coupling hole 1692 a. The second coupling hole 1691a is coupled to the first coupling hole 1143, and the third coupling hole 1692a is coupled to the first coupling hole 1143, thereby stably coupling the rear axle bracket 1691 and the fourth support 114 and stably coupling the power supply bracket 1692 and the fourth support 114. The positions of first connecting hole 1143, second connecting hole 1691a and third connecting hole 1692a are basically consistent, namely, the circle center of first connecting hole 1143, the circle center of second connecting hole 1691a and the circle center of third connecting hole 1692a are basically located on the same straight line, so that first connecting hole 1143, second connecting hole 1691 and third connecting hole 1692a can be fixed through the same connecting piece, that is, the mounting point of rear axle support 1691 and the mounting point of power support 1692 are integrated together, thereby improving the assembly performance of all-terrain vehicle 100, reducing the number of parts of all-terrain vehicle 100 and further realizing the light weight of all-terrain vehicle 100. In the present embodiment, the first coupling hole 1143, the second coupling hole 1691a, and the third coupling hole 1692a may be fixed by the same bolt. The first connecting hole 1143, the second connecting hole 1691a and the third connecting hole 1692a are fixed as follows: the bolts pass through the third connecting hole 1692a, the first connecting hole 1143, and the second connecting hole 1691a in sequence and are fixed by nuts, thereby realizing stable connection of the fourth support 114, the rear axle support 1691, and the power supply support 1692.

It can be understood that the bolts may also be fixed by nuts after passing through the second connecting holes 1691a, the first connecting holes 1143, and the third connecting holes 1692a in sequence, thereby achieving stable connection of the fourth supporting column 114, the rear axle bracket 1691, and the power supply bracket 1692.
