Abstract

A vehicle rear-view side camera is attached to a vehicle cab frame via a linear guide rail (2). The camera is driven by a piston rod (4) of a pneumatic cylinder (1). A linear guide rail (2) is positioned in such a way that in its maximum extension, the camera (6) is outside the vehicle body (5), while in its retracted position, the camera (6) is completely concealed inside the vehicle body (5). A distance sensor (3) is installed at the front section of the vehicle's side camera (6) cover, and the sensor is connected to the vehicle's side camera (6) position control system. The camera (6) position control system includes a power supply (9) and a PLC (10). This PLC (10) is connected via a communication module (11) with the distance sensor (3) and the solenoid valve (12) controlling the operation of the pneumatic cylinder (1).

Description

Vehicle rear-view side camera
The subject of the invention is a rear-view side camera for a vehicle, such as an HGV. The vehicle rear-view side camera replaces the traditional, commonly used side rear-view mirrors. The image captured by the camera is displayed on a tablet shaped screen placed inside the vehicle.
The side cameras currently used in HGVs, like traditional side rear- view mirrors, are attached to the side surfaces of the driver’s cab body and are at risk of damage when driving or manoeuvring the vehicle, especially in areas where space is limited or in narrow passages. The risk of the camera colliding with an obstacle is greater than the collision risk of a conventional side rear-view mirror. While focusing on the reflection in the mirror, the driver can simultaneously assess the position of the mirror relative to the obstacle. When using a camera, the driver of the vehicie does not observe the camera itself, but the image from the camera on the screen.
There are known solutions aimed at protecting the side rear-view mirror against a collision with an obstacle that involve changing the position of the mirror in relation to the surface of the cab body on which it is mounted. Today, most side rear-view mirrors can be folded down, if necessary, so that the mirror surface plane is adjacent to the plane of the cab body. The folding feature of the mirror also means that the mirror folds up during an impact, which can minimize the damage.
US patent US10220787B2 discloses a mirror whose cover is connected to the mounting arm by means of articulated links, first and second links, which jointly rotate relative to the mounting arm and the mirror cover. An actuator is installed at the end of the first link which rotates the first link to move the mirror head between a retracted position and an extended position.
There is known a solution described in the Chinese patent CN106515585A where the mirror is fitted with sensors.
The patent description of the Chinese utility model CN212373260U discloses a retractable rear-view mirror for automobiles whose body is attached to the end of a connecting rod, the other end of which is connected to a vertical rotating rod built into the interior of the vehicle door, in a channel leading to a compartment shaped to accommodate the mirror body, intended for holding a mirror in it. The rotating rod enables rotation of the connecting rod together with the body of the rear-view mirror mounted on it and which results in hiding the mirror in the compartment inside the vehicle door.
From the Korean patent description KR20140124573A a vehicle side mirror is known, installed on the front edge of the window section of the front door of the vehicle in such a way that it is completely hidden in the interior of the vehicle body. The retractable side mirror body is placed on a movable platform that can be extended from inside the door frame to outside the vehicle. The mobile platform is driven by a motor installed inside the door or door frame of the vehicle via a gear transmission.
The aim of the invention is to develop a vehicle side camera, especially a HGV, which retracts inside the vehicle body when an obstacle is detected that may damage the camera.
The vehicle rear-view side camera is attached to the outer surface of the front plate of the linear guide rail, which is fixed to the vehicle cab frame, and the inner surface of the front plate of the linear guide rail is integrated with the piston rod of the pneumatic cylinder, where the linear guide rail is so positioned that in the maximum extension position, the camera is located outside the vehicle body, and the front plate of the linear guide rail is located in the opening in the vehicle body and it is flush with the outer surface of the vehicle body, while in the retracted position, the camera is completely hidden inside the vehicle body. A distance sensor is installed at the outer edge of the front section of the vehicle's side camera cover, and the sensor is electrically connected to the vehicle’s side camera position control system. The vehicle’s side camera position control system includes a power supply and a PLC. This PLC is connected via a communication module with the distance sensor and the solenoid valve controlling the operation of the pneumatic cylinder. Preferably, the distance sensor is a laser sensor.
Preferably, the communication module complies with the l/O-Link standard.
The subject of the invention is explained in more detail on the basis of the embodiments shown in the figures, where Fig. 1 shows the camera in its initial position, Fig. 2 shows the top view of the camera in the retracted position, Fig. 3 shows the camera in the retracted position, Fig. 4 shows the top view of the retracted camera, and Fig. 5 shows a block diagram of the camera position control system.
The vehicle rear-view side camera 6 is attached to the outer surface of the front plate 7 of the linear guide rail 2, and the linear guide rail 2 is attached to the vehicle cab frame, and the inner surface of the front plate 7 of the linear guide rail 2 is integrated with the piston rod 4 of the pneumatic cylinder 1. The linear guide rail 2 is positioned in such a way that in its maximum extension, the camera 6 is outside the vehicle body 5, and the front plate 7 of the linear guide rail 2 is located in the opening 8 in the vehicle body 5 and it is flush with the outer surface of the vehicle body 5, while in its retracted position, the camera 6 is completely concealed inside the vehicle body 5. A distance sensor 3 is installed at the outer edge of the front section of the vehicle’s side camera 6 cover, and the sensor is electrically connected to the vehicle's side camera 6 position control system. The vehicle’s side camera 6 position control system includes a power supply 9 and a Mitsubishi PLC 10, and the PLC 10 is connected to the laser distance sensor 3 via an l/O-Link compliant communication module 11 and a solenoid valve 12 controlling the operation of the pneumatic cylinder 1.
When an obstacle is detected, the distance sensor 3 sends an electrical signal to the PLC 10 via the l/O-Link communication module 11. The PLC 10 sends an electrical signal to the solenoid valve 12, which activates the retraction motion of the pneumatic cylinder 1 piston rod 4, and thus the motion of the camera 6 to the retracted position.
