If there is an obstacle in front, after the vehicle body is hit by the front force, the force will be converted into horizontal and vertical components, reducing the impact in the horizontal direction, avoiding abnormal noise and looseness, and improving the service life; at the same time, the rotational connection between the upper rocker arm 301 and the frame is more stable.
[0045] In the above embodiment of the present application, the second angle may include 0°-6°.
[0046] In the above embodiment of the present application, the second angle may be 10°.

The third line L3 and the fourth line L4 form a fourth angle, and the fourth angle is within a range of 30°-90°. In other words, the fourth angle is greater than or equal to 30° and less than or equal to 90°. This makes the structure of the all-terrain vehicle more stable, ensures that the all-terrain vehicle can withstand greater external loads, and improves the stability of the all-terrain vehicle under various driving conditions.
[0053] In the above embodiment of the present application, the fourth angle may be 60°.
