Abstract

The intelligent vehicle system includes: the turnover bridge type automobile body comprises an automobile body (1), a turnover bridge motor (2), a turnover bridge support (3), a folding bridge (4), a lock hook (5), a sunken sensor (6), a turnover state sensor (7) and a control module (8), wherein the working principle is as follows: firstly, when the vehicle body (1) walks to the edge of the recess, the recess sensor (6) senses the recess and sends the condition to the control module (8), and then the control module (8) drives the turnover bridge motor (2) to enable the turnover plate to slowly rise. When the flap is lifted by about 60 degrees, the latch hook (5) is opened to elastically unfold the folding bridge (4). After these processes are completed, the dent sensor (6) detects that the ground is flat, and the vehicle body (1) will continue to advance.

Description

Intelligent trolley system with folding bridge passing pit

Technical Field

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

Background

In the running games of vehicles, one type is to break through obstacles; the ability to pass obstacles is an important performance of the vehicle. Among them, a depression, i.e., a pit, in a lane is one of the most basic obstacles. In a vehicle body, it is necessary to have a strong ability to pass through a pit. Therefore, the invention provides an intelligent trolley system with a folding bridge and capable of automatically passing through a pit.

Disclosure of Invention

The invention discloses an intelligent trolley system with a folding bridge, which consists of a trolley body 1, a turning bridge motor 2, a turning bridge support 3, the folding bridge 4 and a lock hook 5, wherein wheels and a driving device are arranged below the trolley body 1 and can walk; the potential energy stored by the torsion spring of the folding bridge is released, and the folding bridge is elastically unfolded.

Based on the intelligent trolley system with the folding bridge, the intelligent trolley system further comprises a depression sensor 6 and a turning plate state sensor 7. The depression sensor is arranged at the head position of the vehicle body 1 and used for detecting whether the ground is flat or not; the flap state sensor 7 is arranged below the folding bridge 4 and is used for detecting the state condition of the folding bridge 4.

The control module 8 is installed inside the vehicle body 1, directly controls the running state of the vehicle body 1, and can also be used for receiving detection signals of the depression sensor 6 and the flap state sensor 7 to judge the ground condition and the state of the folding bridge 4 and make corresponding response according to the judged conditions.

The folding bridge 4 has two states, one is a folding state and the other is a state of being unfolded and laid down as a bridge deck, when the folding state is folded, the folding bridge 4 is folded, one end of the folding bridge is fixed on the turning bridge support 3, the other end of the folding bridge is hooked by the lock hook 5 and can not be unfolded, when the folding bridge 4 needs to be unfolded, the turning bridge motor 2 is controlled to rotate, the turning bridge support 3 is rotated, the folding bridge 4 rotates to a certain degree, the lock hook 5 is unhooked, and the folding bridge 4 is unfolded and straightened into a plane as the bridge deck, which is a state of straightening the bridge deck.

The operation principle of the intelligent trolley system with the folding bridge and capable of automatically passing through the pit is as follows: the depression sensor 6 continuously detects during the operation of the system, when the vehicle body 1 moves to the front of the depression, the depression sensor 6 detects the depression of the ground, the control module 7 receives a signal to control the vehicle body 1 to stop, and then the bridge-overturning motor is driven to slowly lift the folding bridge to about 60 degrees. At this point the latch 5 is opened and 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 lays the depression flat as a bridge, the flap state sensor 7 transmits a detection signal to the control module 7, informing the control module 7 that the folding bridge 4 is fully unfolded. The dent sensor 6 now sends a detection signal that the ground is flat to the control module 7, and the control module 7 continues to drive the car body 1 forward through the paved deck.

Detailed Description

Detailed description of the invention

The embodiment is described with reference to fig. 1, and the operation principle of the intelligent trolley system with the folding bridge and capable of automatically passing through the pit in the embodiment is as follows: after the system is turned on, the vehicle body 1 is moved forward. The recess sensor 6 continuously detects whether the ground is flat or not in the system operation process, when the vehicle body 1 runs to a recess, the recess sensor 6 detects that the ground is recessed, the control module 7 receives a signal to control the vehicle body 1 to stop, and then the bridge turnover motor is driven to enable the folding bridge to be slowly lifted to about 60 degrees. At this point the latch 5 is opened and 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 lays the depression flat as a bridge, the flap state sensor 7 transmits a detection signal to the control module 7, informing the control module 7 that the folding bridge 4 is fully unfolded. The dent sensor 6 now sends a detection signal that the ground is flat to the control module 7, and the control module 7 continues to drive the car body 1 forward through the paved deck.
