Since the driving wheels 2 protrude from the supporting plane, in a state of turning the upper surface of the dump truck downward, the driving wheels 2 on both sides can contact the ground and provide the required speed for rolling and straightening again under the action of the driving wheels 2. Under the action of the rolling support part, when the forward inertia of the dump truck is large, the dump truck does not need to be driven, and can roll along the front surface, the driving wheel 2, the rolling support part and the rear surface in sequence; when the forward inertia of the dump truck is small, the dump truck can be clamped between the front surface and the rolling support part, the dump truck can contact the ground due to the protrusion of the driving wheel 2, the dump truck is driven to move by controlling the rotation of the driving wheel 2, and the required initial speed is provided for the swing of the dump truck.

In other embodiments, it is understood that the position of the two side driving wheels 2 contacting the ground when rolling may be a supporting plane formed by the driving wheels 2 protruding between the rolling supporting part and the rear surface of the vehicle housing 1. It will be understood that the specific shape of the roll support may be various, such as a boss structure provided on the vehicle housing, or a protruding rod structure, or a protruding plate structure, as long as it is protruded from the two driving wheels 2, but the protruded height is within a set range, which allows the two driving wheels 2 to protrude from the contact plane of the front surface of the vehicle housing and the roll support when touching the ground, or the contact plane of the rear surface of the vehicle housing and the roll support when touching the ground.

As shown in fig. 1 and fig. 2, for the embodiment of the roll support, the roll support includes at least two wing plates 6, one end of each of the wing plates 6 is connected to the upper surface of the car housing 1, and the other end of each of the wing plates 6 extends to the driving wheel 2 on both sides. The top end of the wing plate 6 is provided with a support rod 7, and the support rod 7 is arc-shaped and is positioned above the driving wheel 2. Because the wing plates 6 extend towards the two driving wheels 2, the tip lorry cannot be clamped between the driving wheel 2 on one side and the lorry shell 1 when the tip lorry is laterally inclined, and the problem of lateral overturning is avoided. The supporting rod 7 is positioned above the driving wheel 2, so that the dump truck is prevented from running in a turning posture, and in the embodiment, the wing plates 6 on two sides are connected into a whole and are fixedly installed on the upper surface to form a U-shaped branched structure. It will be appreciated that the number of wings 6 may be more than three, for example four wings 6 arranged on both sides.

The rolling buffer part 8 is cylindrical, and promotes rolling of the dump truck during traveling. It is understood that the tumbling damper 8 may also be a polygonal prism or a spherical structure, which may serve as a fulcrum for initiating tumbling and facilitate the tumbling action, i.e., function as the tumbling damper 8. The tumbling cushion part 8 is made of an elastic material, and the tumbling cushion part 8 made of plastic or rubber such as elasticity further increases the tumbling effect and reduces the shock of the collision.

As shown in fig. 2, in order to further enhance the rolling motion of the dump truck, the truck case 1 of the present embodiment is specifically provided with a spherical boss 10 on the front surface of the truck case 1. The vehicle housing 1 is further provided with a driven wheel 9, which driven wheel 9 is located at the rear side of the vehicle housing 1. The driven wheel 9 and the driving wheels 2 on two sides form a three-point stable supporting structure, so that the vehicle can keep stable in a constant speed and static state. The spherical bosses 10 enable the dump truck to overturn from more directions when rolling, and the playing pleasure of the dump truck is increased.

The mounting axes of the two motors 3 and the axis of the transmission shaft 13 are parallel to each other and have a set distance, so that the battery compartment 5 and the driving circuit are mounted between the vehicle case 1 and the motors 3. The front surface is arc-shaped connected with the upper surface, and the rear surface is arc-shaped connected with the upper surface. Under the condition of high speed, the arc connection can directly promote the dump truck to overturn and straighten, and under the condition of low speed, the dump truck can also overturn and straighten quickly under the action of the driving wheels 2. Because the utility model discloses a drive wheel 2 is great, and car casing 1 is less, and motor 3 is skew the axletree setting of drive wheel 2 can provide battery compartment 5 and control circuit 4's installation.

As shown in fig. 4, the arrow indicates the direction of movement of the dump truck, and the working principle of the present invention is as follows: and in a static and uniform state, the driving wheels 2 at the two sides and the driven wheels 9 at the rear support the dump truck to keep static. In the deceleration state after the movement, the dump truck leans forward, the rolling buffer part 8 firstly contacts the ground, and the two driving wheels 2 are driven to leave the ground as a pivot under the cylindrical structure, and the dump truck enters the overturning state. Under the condition of large deceleration, the dump truck completely rolls from the front surface of the truck shell 1 through the two wing plates 6 and the rear surface and returns to the final state of the dump truck; under the condition of smaller deceleration, after the dump truck rolls from the front surface to the two wing plates 6, kinetic energy is not enough to continuously roll to the dump truck to be aligned, at the moment, the dump truck is clamped between the front surface and the wing plates 6 or the wing plates 6 are arranged between the rear surface, and the driving wheel 2 protrudes out of the tangent planes of the front surface and the wing plates 6 and protrudes out of the tangent planes of the rear surface and the ejection structure, so that the driving wheel 2 can contact the ground, the motion of the dump truck is continuously controlled through remote control, power is provided for the dump truck, the dump truck is enabled to continuously roll until the dump truck is aligned, and a player does not need to manually align the dump truck in the process. Under the action of the spherical boss 10, or the driving wheel 2 on one side of the dump truck collides with an obstacle, the dump truck rolls along an unconventional rolling plane and inclines to the left side or the right side, the supporting plate on one side after rolling is in contact with the ground in preference to the driving wheel 2, the dump truck topples to the other side after collision and runs to a turning state with the upper surface facing downwards, and the driving wheel 2 is continuously controlled to rotate at the moment, so that the dump truck can be righted.
