Description

Container truck reversing video assistance system

technical field

The invention belongs to the field of rear-view video auxiliary technology for container trucks when they are reversing.

Background technique

A long container truck is divided into a tractor and a trailer. When it needs to load and unload the cargo berth to reverse, the tractor and the trailer often cannot form a straight line. In severe cases, the tractor and the trailer form a 90-degree angle. The tractor and the trailer are not arranged in a straight line. When reversing, you can't see anything behind and on both sides of the trailer when you look at the rearview mirror in the cab, which brings great danger to the driver's safe driving. In this case, the driver usually hires a navigator (co-pilot) to guide him, but this not only increases the transportation cost, but also a container truck with a length of more than 20 meters and a height of more than 4 meters is like a tall and big The navigator can't take into account all aspects in front of this behemoth. Therefore container truck is easy to take place accident that shouldn't happen when reversing. On the other hand, although the bottom of some trailers is equipped with a reversing camera, because the camera is installed at the bottom of the trailer, the images it takes can only reflect the situation on one side of the trailer, and cannot see information from other directions, let alone include The relative positional relationship between the vehicle, especially the two rear sides and the surrounding obstacles, has a greatly discounted indication reference value. These situations under the prior art are the main reasons that the container truck has an accident because of reversing.

How to let the driver of the container truck also can see the relative position relationship between the back of the container and the rear two sides and the obstacle in the cab, so as to provide more information for the reversing berth of the container truck, which is the starting point of the present invention .

Contents of the invention

In order to enable the driver of the container truck to see more clearly the relative positional relationship between the back of the container truck and the rear sides and the obstacles in the driver's cab when reversing the berth or loading and unloading goods, the present invention has taken the following technical measures: The container truck reversing video auxiliary system is installed at the back. The container truck reversing video auxiliary system mainly includes: balloons, cameras, compressors, solenoid valves, gas tanks, etc. The balloon is connected to one end of the rubber hose, the rubber hose is wound on the reel, and the other end of the rubber hose is connected to the air passage of the rotating shaft. The rotating shaft and the reel are driven by the motor to rotate and retract the rubber hose and balloon. The motor is connected to the controller in the cab, and the joint is installed On the rotating shaft, there is an air passage between the rotating shaft and the joint, the joint is connected to the compressor and the solenoid valve, and the compressor and the solenoid valve are connected to the gas tank, which stores gas lighter than air, as shown in Figure 1; the camera is installed On the balloon and connect to the monitor in the cab.

The benefit of doing like this is: the balloon can be retracted by the driver by controlling the motor, the compressor and the electromagnetic valve. The camera is installed on the balloon. Since the gas contained in the gas tank is lighter than air, when the solenoid valve is opened to inflate the balloon and the reel is driven by the motor to release the balloon, the balloon will rise together with the camera. When the balloon rises to a certain height, the camera on the balloon can condescendingly shoot the situation behind the container truck and behind the sides, so that the driver of the container truck can view the rear of the trailer and the sides of the trailer from an unprecedented height and angle of view in the cab Behind, including everything about the trailer itself. The driver of the container truck can obtain more and wider information when reversing, which greatly improves the safety of the container truck when reversing; when the driver finishes reversing, he can also control the compressor to pump the gas in the balloon back into the gas tank for preparation Next time it will be reused, and at the same time, the motor will be controlled to drive the reel to rotate, and the rubber hose and balloon will be retracted into the storage box to complete the task; help, which is another benefit of the invention.

detailed description

In order to enable the driver of the container truck to see more clearly the relative positional relationship between the rear of the container truck, the two rear sides and the obstacles in the driver's cab when loading and unloading cargo at the reversing berth, the present invention adopts the method of installing the container truck at the back of the trailer. The technical measure of the car reversing video assistance system. The container truck reversing video auxiliary system is mainly composed of balloons, cameras, compressors, solenoid valves, and gas tanks. One end of the rubber hose is connected to the balloon, and the rubber hose is wound on the spool. The other end of the rubber hose is connected to the air passage of the rotating shaft, and the rotating shaft and the coil are driven by a motor to rotate and retract the rubber hose and the balloon. The motor is connected to the controller in the cab, and the driver can control the rotation of the motor through the controller to realize the retraction and release of the balloon; the joint is installed on the rotating shaft, and there is an air passage in the rotating shaft to communicate with the joint. This structure can make the rotating shaft and the wire reel It can also inflate and discharge gas to the balloon when rotating. The compressor and the solenoid valve are connected by a live connection, and the compressor and the solenoid valve are connected to the gas tank, which stores gas lighter than air. The purpose of this structure is to realize the recycling of gas, as shown in Figure 1; the camera is installed in On the balloon and connected to the monitor in the cab, the driver can see the images captured by the camera on the monitor in the cab.

In order to solve the technical problem that the balloon can be filled and released with gas even when the reel and the rotating shaft are rotating, the present invention adopts the method of processing an air channel on one end of the rotating shaft and the joint, and the joint is installed on the rotating shaft to keep the air channel unblocked. Then, through the method of connecting with the compressor and the electromagnetic valve, it is realized that the balloon can also be filled and discharged with gas when the wire disc and the rotating shaft are rotating, as shown in Figure 3.

Working process of the present invention: when the driver wants to reverse the berth to load and unload goods, the driver can control the solenoid valve 3 to open in the cab, and the gas in the gas tank 1 is inflated to the ball 10 through the pipeline, the solenoid valve 3 and the union 4. The balloon 10 begins to expand, and then the driver starts the motor through the controller to drive the wire reel 6 to rotate and release the balloon 10 . Since the gas put into the balloon 10 is lighter than air, the balloon starts to rise at this moment. When the balloon rises to a certain height, the camera starts to work, as shown in Figure 2. The driver turns on the monitor in the cab. You can see that the camera on the balloon is condescending to shoot the specific situation between the back of the container truck and the two rear sides and the obstacles, so that the driver of the container truck can view the rear of the trailer and the rear two sides from an unprecedented height and angle of view in the cab. any obstacles on the side. The driver of the container truck can obtain more and wider range of information when reversing, providing an objective basis for choosing the appropriate operation, and greatly improving the safety of reversing; when the driver completes reversing, he can control the compressor to turn the balloon inside The gas pump is returned in the gas tank, and the motor-driven reel is controlled to rotate and the balloon is recovered in the storage box 9 to complete the task.
