Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle camera technology, and in particular to a cleaning device, camera system, and vehicle. Background Technology
[0002] Vehicles are typically equipped with camera systems. These cameras monitor the vehicle's external environment, displaying the footage on a screen inside the vehicle. However, since cameras are located in the external environment, conductive or obstructing media inevitably accumulate on the lens surface. Conductive media include fog or water droplets; obstructing media include impurities. This can cause distortion in the monitored images. If these media are not removed in a timely manner, it can also lead to vehicle safety issues.
[0003] In existing camera systems, when image distortion is detected on the display screen, it indicates the presence of a medium on the lens surface. A fan is used to blow away the medium from the lens surface. However, there is a lag in the removal of the medium. If the medium is not removed in time, it will affect the light transmission of the lens. Utility Model Content

To achieve the above objective, the technical solution of this utility model is as follows:
[0005] A cleaning device is applied to a light-transmitting part, the light-transmitting part including a light-transmitting surface and a light-transmitting body, the light-transmitting surface being disposed on the end face of the light-transmitting body, and the cleaning device including an air guide part, a first conductive part, and a second conductive part;
[0006] The air guide is disposed on the radially outer side of the light-transmitting body, forming an air duct between the air guide and the light-transmitting body. One end of the second conductive part is connected to the air guide, and the other end of the second conductive part extends to the radially outer side of the light-transmitting surface and is movably attached to the light-transmitting surface. The first conductive part is disposed on the light-transmitting surface, and a gap exists between the first conductive part and the second conductive part on the light-transmitting surface.
[0007] When a conductive medium is present in the gap, the first conductive part and the second conductive part are connected to form a first circuit, and the air duct delivers airflow to the light-transmitting surface.
[0008] Specifically, it also includes a controller and a blower, the controller being electrically connected to the blower, the blower being connected to the air guide, and the controller being communicatively connected to the first circuit.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0030] Example 1
[0031] This embodiment provides a cleaning device for removing conductive and / or obstructing media from the light-transmitting part 1. Specifically, the light-transmitting part 1 can be the lens of a camera, which can be installed on a vehicle to monitor the vehicle's external environment. Since the camera is installed in the external environment, fog, water droplets, or impurities on the camera lens need to be removed promptly to ensure the camera's normal operation. By installing a cleaning device on the camera, conductive and / or obstructing media on the camera lens can be removed, as detailed below.
[0032] like Figures 1-3 As shown, the cleaning device includes an air guide 2, a first conductive part 3, and a second conductive part 4. The air guide 2 is disposed on the radial outer side of the light-transmitting body 12, and an air duct 21 is formed between the air guide 2 and the light-transmitting body 12. One end of the second conductive part 4 is connected to the air guide 2, and the other end of the second conductive part 4 extends to the radial outer side of the light-transmitting surface 11 and is movably attached to the light-transmitting surface 11. The first conductive part 3 is disposed on the light-transmitting surface 11, and there is a gap between the first conductive part 3 and the second conductive part 4 on the light-transmitting surface 11. When a conductive medium is present in the gap, the first conductive part 3 and the second conductive part 4 are electrically connected to form a first circuit, and the air duct 21 delivers airflow to the light-transmitting surface 11.
[0033] The cleaning device also includes a controller and a blower 5. The controller and the blower 5 are electrically connected to form a second circuit. The blower 5 is connected to the air guide 2 to enable the blower 5 to deliver air to the air duct 21. The controller is communicatively connected to the first circuit. When the first circuit is connected, the controller controls the blower 5 to start for a preset time, or when there is a conductive medium and / or a light-blocking medium on the light-transmitting surface 11, the controller controls the blower 5 to start.
[0034] The blowing device 5 is connected to the side wall of the air guide 2. After the airflow enters the air duct 21, it circulates along the circumference of the air duct 21, which can effectively and evenly dissipate the airflow. The airflow pushes open the second conductive part 4. After the second conductive part 4 is deformed, the airflow is led out along the circumference of the air duct 21 and blows on the light-transmitting surface 11, which can quickly and evenly remove the fog or water droplets from the light-transmitting surface 11.
[0035] The cleaning device can be used in two ways. One is passive activation. When there is a conductive medium on the light-transmitting surface 11, the second conductive part 4 and the first conductive part 3 are electrically connected to form a first circuit. The controller obtains a circuit connection signal from the first circuit and activates the blower 5 through the second circuit according to the circuit connection signal, thereby blowing air into the air duct 21. The blower 5 is in a delayed working state. Whenever the blower 5 is activated, it will turn off after a default preset working time. This means that the duration of continuous air blowing by the blower 5 is sufficient to remove the conductive medium on the light-transmitting surface 11. The other is active activation. When there is a conductive medium and / or a light-blocking medium on the light-transmitting surface 11, the second conductive part 4 and the first conductive part 3 have not yet formed an effective electrical connection. However, at this time, it can be confirmed through the image information of the camera that there is a conductive medium and / or a light-blocking medium on the light-transmitting surface 11. The controller can independently control the blower 5 to start so that the blower 5 can blow air into the air duct 21 in a timely manner.
[0036] In this embodiment, there is a gap between the first conductive part 3 and the second conductive part 4 on the light-transmitting surface 11. When there is a conductive medium in the gap, the first conductive part 3 and the second conductive part 4 are connected to form a first circuit. The air duct 21 delivers airflow to the light-transmitting surface 11. The air duct 21 can deliver air to the light-transmitting surface 11 in a timely manner and remove the conductive medium from the light-transmitting surface 11, ensuring the light transmission performance of the light-transmitting part 1. The camera can transmit normal images, improving the driving safety of the vehicle.
[0037] In one embodiment, the second conductive part 4 is concentrically disposed with the first conductive part 3, and the second conductive part 4 is disposed radially outside the first conductive part 3.
[0038] The air guide 2 is arranged around the outer periphery of the light-transmitting part 1. The second conductive part 4 has a roughly annular structure, and the corresponding first conductive part 3 has a roughly annular structure. When the mist or water droplets are unevenly distributed on the light-transmitting surface 11, a large electrical conduction area can be formed between the second conductive part 4 and the first conductive part 3. The second conductive part 4 and the first conductive part 3 are more likely to form an effective first circuit, further improving the reliability of the cleaning device.
[0039] The second conductive part 4 and the first conductive part 3 are arranged concentrically. The distance between the second conductive part 4 and the first conductive part 3 is the radial difference between the inner circumference of the second conductive part 4 and the outer circumference of the first conductive part 3. The radial difference is set within a reasonable range so that electrical connection can be made when there is fog or water droplets between the second conductive part 4 and the first conductive part 3; and avoids the radial difference being too large, which would affect the electrical connection between the second conductive part 4 and the first conductive part 3.
[0040] The first conductive part 3 can be a metal ring. The first conductive part 3 and the light-transmitting surface 11 can be fixed by adhesive bonding, which can effectively and quickly fix the first conductive part 3 without affecting its conductivity.
[0041] In one embodiment, the air duct 21 is provided with an air outlet near the second conductive part 4, and the light-transmitting surface 11 protrudes axially from the air outlet.
[0042] When the light-transmitting surface 11 does not require the removal of conductive medium and / or light-shielding medium, the second conductive part 4 can effectively block the air duct 21, playing a certain role in dust prevention. The light-transmitting surface 11 is axially protruding from the air outlet, so that the second conductive part 4 is in close contact with the light-transmitting surface 11, further improving the sealing performance of the second conductive part 4 and effectively preventing dust or rainwater from entering the air duct 21.
[0043] In one embodiment, the second conductive part 4 is made of a flexible conductive material. A first end 42 is provided on the outer periphery of the second conductive part 4, and a second end 43 is provided on the inner periphery of the second conductive part 4. The first end 42 is connected to the air guide part 2, and the second end 43 is attached to the light-transmitting surface 11. The thickness of the first end 42 is greater than the thickness of the second end 43.
[0044] The second conductive part 4 can be a conductive adhesive strip. When the second conductive part 4 is in contact with the light-transmitting surface 11, the second conductive part 4 and the light-transmitting surface 11 are in a sealed state. The second conductive part 4 is deformed by the airflow. The thickness of the first end 42 is greater than the thickness of the second end 43. The second end 43 is more easily pushed open by the airflow, thereby achieving the separation of the second conductive part 4 from the light-transmitting surface 11. The second conductive part 4 can still guide the airflow to sweep on the light-transmitting surface 11.
[0045] In one embodiment, the cleaning device further includes a housing 6, which is connected to the light-transmitting body 12, and the air guide 2 and the air blowing device 5 are both mounted on the housing 6.
[0046] The first conductive part 3 is connected to a first wire 31, which passes through the light-transmitting part 1. The second conductive part 4 is connected to a second wire 41. Both the first wire 31 and the second wire 41 are connected to an external power source to form a first circuit.
[0047] The first wire 31 can pass through the light-transmitting part 1 and then be led out from the housing 6, so as to avoid the first wire 31 blocking the light-transmitting surface 11. The second wire 41 can pass along the outer wall of the air guide part 2, pass through the air blowing device 5 and then be led out from the housing 6, so as to make the wiring trajectory of the first wire 31 and the second wire 41 more reasonable and avoid them being fully exposed on the cleaning device, which would affect the appearance.
