Description

Intelligent trolley system with its own folding bridge to cross the pit

technical field

The invention belongs to automation equipment, and relates to an intelligent trolley system with its own folding bridge to automatically pass through a pit, which is used in the field of home entertainment.

Background technique

In the car running game, there is one type of passing through obstacles; the ability to pass through obstacles is an important performance of the car. Among them, there is a depression in the driveway, which is a pit, which is the most basic obstacle. In a car body, it is necessary to have a strong ability to pass through pits. To this end, the present invention proposes an intelligent trolley system with its own folding bridge to automatically pass through the pit.

SUMMARY OF THE INVENTION

The invented intelligent trolley system with its own folding bridge is composed of a car body 1, a turning bridge motor 2, a turning bridge bracket 3, a folding bridge 4 and a locking hook 5; The bridge motor 2 is fixed on the front end of the vehicle body 1, and drives the turning bridge bracket 3 to rotate; the turning bridge bracket 3 is used for one end of the folding bridge 4; There is a torsion spring, which makes the folding bridge 4 open into a plane as a bridge deck; the lock hook 5 is a curved hook, one end is fixed, and the other end is a hook. When the angle is reached, the lock hook will be opened; the potential energy stored by the torsion spring of the folding bridge is released, and the folding bridge is elastically unfolded.

Based on the aforementioned intelligent trolley system with its own folding bridge, it also includes a depression sensor 6 and a flap state sensor 7 . The depression sensor is installed at the front of the vehicle body 1 to detect whether the ground is flat; the flap state sensor 7 is installed under the folding bridge 4 to detect the state of the folding bridge 4 .

The control module 8 is installed inside the vehicle body 1 to directly control the running state of the vehicle body 1, and can also be used to receive the detection signals of the depression sensor 6 and the flap state sensor 7 to judge the ground conditions and the state of the folding bridge 4, and to judge the state according to the judgment. respond accordingly.

The folding bridge 4 has two states, one is the folded and retracted state, and the other is the state of opening and laying down as a bridge deck; in the folded and retracted state, the folding bridge 4 is folded, one end is fixed on the flip bridge bracket 3, and the other end is folded. The lock hook 5 is hooked and cannot be opened: when the folding bridge 4 needs to be opened, the motor 2 of the flip bridge is controlled to rotate, and the flip bridge bracket 3 is rotated, so that the folding bridge 4 has a certain rotation, and the lock hook 5 is unhooked, then the folding The bridge 4 is opened and straightened into a plane, as the bridge deck, which is the straightened bridge deck state.

The operating principle of the intelligent trolley system with its own folding bridge to automatically pass through the pit is: during the operation of the system, the sag sensor 6 continues to detect, when the vehicle body 1 runs before the sag, the sag sensor 6 detects the ground sag, and the control module 7 accepts it. When the signal controls the car body 1 to stop, then drive the axle flip motor to slowly lift the folding axle up to about 60 degrees. At this time, the hook lock 5 is opened, the potential energy stored by the torsion spring of the folding bridge 4 is released, and the folding bridge 4 is elastically unfolded. When the folding bridge 4 is fully unfolded and flattens the depression as a bridge, the flap state sensor 7 transmits a detection signal to the control module 7 to inform the control module 7 that the folding bridge 4 is fully unfolded. At this time, the depression sensor 6 transmits a detection signal that the ground is flat to the control module 7, and the control module 7 continues to drive the vehicle body 1 to run forward through the paved bridge deck.

Detailed ways

Specific implementation one

This embodiment is described with reference to FIG. 1 . In this embodiment, the operating principle of the invented intelligent trolley system with its own folding bridge to automatically pass through the pit is: after the system is turned on, the vehicle body 1 runs forward. During the operation of the system, the depression sensor 6 continuously detects whether the ground is flat. When the vehicle body 1 runs to the depression, the depression sensor 6 will detect the depression on the ground, and the control module 7 receives the signal to control the vehicle body 1 to stop, and then drives the flip motor. Raise the folding bridge slowly until about 60 degrees. At this time, the hook lock 5 is opened, the potential energy stored by the torsion spring of the folding bridge 4 is released, and the folding bridge 4 is elastically unfolded. When the folding bridge 4 is fully unfolded and flattens the depression as a bridge, the flap state sensor 7 transmits a detection signal to the control module 7 to inform the control module 7 that the folding bridge 4 is fully unfolded. At this time, the depression sensor 6 transmits a detection signal that the ground is flat to the control module 7, and the control module 7 continues to drive the vehicle body 1 to run forward through the paved bridge deck.
