Description

Technical Field

[0001] The present invention relates to the field of unmanned vehicle-mounted camera, and more particularly to a vehicle-mounted camera device with self-adjusting effect based on unmanned driving. Background Art

[0002] The on-board camera is the core sensing device in the ADAS system and the field of automobile autonomous driving. It mainly realizes the image information collection function through lenses and image sensors, can achieve all-round visual perception, and make up for the defects of radar in object recognition. It can realize traffic light recognition and traffic sign recognition. Compared with lidar, the camera lens has low cost and high algorithm and technology maturity, so it has a higher object recognition rate, which makes the on-board camera of great significance to driverless cars.

[0003] When the existing vehicle-mounted camera equipment for driverless cars is in use, in order to ensure the cleanliness of the camera lens shooting picture, a cleaning sponge is usually used to wipe or a cleaning agent is sprayed on the surface of the camera lens to clean the surface of the vehicle camera equipment. However, when the driverless car is driving, it is usually encountered that paper or film is pressed and blocked on the camera surface, or cardboard is maliciously glued to the surface of the camera to block it. This makes it impossible for the camera to effectively obtain image information during the driving of the driverless car, and further makes the driverless car obtain incomplete road condition information during driving, affecting driving safety.

[0004] To this end, we propose a vehicle camera device with self-adjusting effect based on unmanned driving to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a vehicle camera equipment with self-adjusting effect based on unmanned driving. The airflow can be discharged through the air outlet pipe during the driving of the unmanned vehicle, and the obstructions covering the camera surface due to the pressure difference can be blown away. For obstructions that are maliciously glued and blocked, the insulating oil on the surface of the blocking net can be diffused to the bonding point between the obstruction and the surface of the camera housing by using warm liquid droplets, and the bonding effect can be weakened by using the insulating oil. Then, under the impact of subsequent airflow, the obstructions in the glued state can also be detached, thereby ensuring the cleaning of obstructions on the camera surface during the driving of the unmanned vehicle and ensuring the effectiveness of the camera information acquisition screen.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) The present invention is equipped with an air outlet duct, a baffle and a boost nozzle. After the airflow is pressurized by the boost nozzle, the airflow is accelerated to pass through the baffle and then blow toward the front of the camera housing. With the help of the impact of the airflow, the obstruction covering the surface of the camera housing can be blown away, and the camera component will not be obstructed, so that the camera component can smoothly take pictures, provide image information for the unmanned vehicle, and then judge the road conditions of the vehicle.

[0024] (2) The present invention is equipped with a rubber ball, an outer cover, a ventilating pipe, a ball bag and an air guide pipe. After the air outlet pipe is blocked by a glued obstruction, the internal pressure of the air outlet pipe continues to increase, thereby squeezing the rubber ball, causing the ball bag to fall into the air outlet pipe through the outlet, and after being punctured by the sharp corners of the surface of the blocking net, the insulating oil inside is exposed and spilled on the surface of the blocking net. Through the diffusion of water vapor, the droplets containing the insulating oil diffuse to the bonding surface, and the glue is dissolved by the insulating oil, thereby weakening the bonding effect. Afterwards, under the action of the impact airflow, the obstruction is smoothly separated from the surface of the camera housing, so that the surface of the camera housing can smoothly obtain road condition information again.

[0025] (3) The present invention is equipped with an air guide tube and a heating layer. The water-soluble film is made of a water-soluble polymer material that dissolves rapidly in water. Its water solubility is related to its thickness and temperature. The heat layer can make the droplets entering the air outlet pipe have high temperature, which accelerates the dissolution of the water-soluble film and reduces the blockage of the baffle by the water-soluble film.

[0026] (4) The present invention is equipped with an insect repellent box, a control valve and Xiong Angbao. When the driverless car is driving and starting, the control valve is kept closed. When the driverless car is in a braking or closed state, the control valve is opened, so that the volatile smell of the mothballs can enter the air outlet duct along the hose, thereby forming an insect repellent treatment on the surface of the camera housing, preventing mosquitoes from approaching the surface of the camera to block the camera, thereby ensuring the clarity of the camera shooting picture.

[0043] Embodiment 1:

[0044] See also Figure 1-Figure 5 and Figure 7-10 A vehicle camera device with self-adjusting effect based on unmanned driving includes a camera housing 1 and an air outlet duct 4. A panel 20 is installed on the front of the camera housing 1. The air outlet duct 4 is installed inside the panel 20. A camera assembly 3 is installed inside the camera housing 1. A photosensitive ring 17 is sleeved on the surface of the camera assembly 3, and the photosensitive ring 17 is located on the inner side of the air outlet duct 4.

[0045] A baffle 8 is installed inside the air outlet pipe 4, and the surface of the baffle 8 is provided with a sharp corner, a hemispherical outer cover 7 is installed on the back of the baffle 8, and a vent pipe 9 is evenly installed on the surface of the outer cover 7, a rubber ball 10 is embedded and installed inside the baffle 8, and the rubber ball 10 is located in front of the outer cover 7, a booster nozzle 6 is installed on the inner wall of the air outlet pipe 4, and the booster nozzle 6 is located behind the outer cover 7, the inside of the rubber ball 10 is filled with a ball bag 11, and the ball bag 11 is made of a water-soluble film, and insulating oil is stored inside the ball bag 11, and an outlet 12 is provided on the surface of the rubber ball 10, and the outlet 12 is located between the outer cover 7 and the baffle 8;

[0046] An air inlet pipe 5 is installed through the top of the camera housing 1, and the tail end of the air inlet pipe 5 is sealed and connected to each group of air outlet pipes 4 through multiple groups of hoses. A breathable membrane 18 and a one-way valve 19 are installed inside the ventilation pipe 9, and the breathable membrane 18 is located on the side of the one-way valve 19 close to the outer cover 7.

[0047] Specifically, the vehicle camera device is installed on an unmanned vehicle. When the vehicle is driving, a pressure difference is formed between the vehicle in motion and the air, thereby generating an airflow. The airflow passes through the air inlet pipe 5 and is then transported to the air outlet pipe 4 with a check valve installed therein through a hose. After being pressurized by the booster nozzle 6, the airflow is accelerated through the baffle 8 and then blows toward the front of the camera housing 1. With the help of the impact of the airflow, the obstruction covering the surface of the camera housing 1 can be blown away, thereby not obstructing the camera assembly 3, so that the camera assembly 3 can smoothly perform camera work, provide image information for the unmanned vehicle, and then judge the road conditions of the vehicle.

[0048] When the obstruction on the surface of the camera housing 1 is a glued cardboard or plastic film, it is difficult for the airflow impulse through the air outlet on the surface of the air outlet pipe 4 to blow away the glued object. At this time, the port of the air outlet pipe 4 is blocked, so that the airflow that originally passed in one direction is forced to return, and then enters the interior of the outer cover 7 in one direction through the ventilation pipe 9. As the car continues to drive and the airflow is continuously transported, the pressure inside the air outlet pipe 4 continues to increase, and then the rubber ball 10 is squeezed, so that the ball bags 11 inside the rubber ball 10 fall into the air outlet pipe 4 through the outlet 12 one by one under the squeezing effect. Under the action of the airflow, the ball bags 11 hit the surface of the blocking net 8, and after being pierced by the sharp corners of the surface of the blocking net 8, the insulating oil inside is exposed and sprinkled on the surface of the blocking net 8;

[0049] At the same time, due to the blocking of the adhesive, the light intensity data detected by the light-sensitive ring 17 is in a continuous blocking state, and cooperates with the camera to judge the environment on the surface of the camera housing 1, and judge that the camera housing 1 is in a poor light condition or there is a blocking object, and then the electromagnetic valve is started through the central processor;

[0050] After the solenoid valve is started, the air duct 13 transports the heated atomized water vapor to the inside of the air inlet pipe 5, and then transports it to the air outlet pipe 4 through the hose. The insulating oil on the surface of the baffle 8 is transferred to the surface of the obstruction by the diffusion of water vapor, and the droplets containing the insulating oil are diffused to the bonding surface under the diffusion of water vapor. The glue is dissolved by the insulating oil, thereby weakening the bonding effect. After that, the obstruction is smoothly separated from the surface of the camera housing 1 under the action of the impact airflow, so that the surface of the camera housing 1 can smoothly obtain the road condition information again.

[0051] In addition, the water-soluble film is made of a water-soluble polymer material that dissolves rapidly in water. Its water solubility is related to its thickness and temperature. The higher the temperature, the shorter the dissolution time. Therefore, in order to reduce the blockage of the baffle net 8 by the water-soluble film after the ball bag 11 is punctured, the droplets entering the air outlet pipe 4 need to be heated.

[0052] See also Fig.11 The camera component 3 includes a camera, an image signal processor, a serializer, a deserializer, a camera data receiver, a central processing unit and a firmware memory. The output end of the camera is electrically connected to the image signal processor, the output end of the image signal processor is electrically connected to the firmware memory and the serializer, the output end of the serializer is electrically connected to the deserializer, the output end of the deserializer is electrically connected to the camera data receiver, and the output end of the camera data receiver is electrically connected to the central processing unit.

[0053] Specifically, the camera is a depth camera that can obtain depth and color information of the environment. When the surface of the camera housing 1 is covered with box-type or shell-type obstructions, the camera can promptly shoot and transmit data to the central processor. When it is determined that there are box-type or shell-type obstructions on the surface of the camera housing 1, a signal can be sent to the solenoid valve to start the air duct 13.

[0054] See also Figure 6 An air duct 13 is installed through the surface of the air inlet pipe 5, a solenoid valve is installed on the surface of the air duct 13, and the solenoid valve is electrically connected to the central processing unit, an atomizing nozzle 16 is installed inside the end port of the air duct 13 close to the air inlet pipe 5, a temperature insulation layer 14 and a heating layer 15 are installed inside the air duct 13, and the heating layer 15 is located on the inner side of the temperature insulation layer 14, and the heating layer 15 is electrically connected to the central processing unit.

[0055] Specifically, the tail end of the air guide pipe 13 is externally connected to a micro water pump on the driverless car, and the input end of the micro water pump is connected to the water tank on the car through a pipeline. Therefore, after the solenoid valve on the surface of the air guide pipe 13 is started, water can be transported to the inside of the air inlet pipe 5, and the water flow is processed into small droplets under the action of the atomizing nozzle 16, thereby increasing the contact area with the insulating oil on the surface of the baffle 8 when passing through the baffle 8 later;

[0056] By heating the water inside the air guide tube 13 through the heating layer 15, the droplets entering the air outlet pipe 4 are heated, which can accelerate the water solubility of the broken ball bag 11 after contact with the droplets, avoid clogging of the baffle 8, and ensure stable output of airflow.

[0057] See also Figure 1 The panel 20 is made of a light absorbing plate, and a light source lamp bead is embedded and installed on the back of the light sensitive ring 17, and the light source lamp bead is electrically connected to the light sensitive ring 17.

[0058] Specifically, the light-absorbing plate can absorb the external reflections during the driving of the driverless car, thereby ensuring the clarity of the camera's shooting images;

[0059] In addition, the light-sensitive ring 17 can detect the light intensity in the environment where the camera is located, and then start the light source lamp beads to perform fill light processing when the light intensity is insufficient, thereby ensuring the clarity of the camera shooting picture.

[0060] See also Figure 1 The bottom of the camera housing 1 is connected to a mounting base 2 via a damping shaft rod, and a vacuum suction cup is installed at the bottom of the mounting base 2.

[0061] Specifically, the mounting base 2 is adsorbed and mounted on the surface of the driverless car by a vacuum suction cup, and the angle between the camera housing 1 and the mounting base 2 is adjusted by a damping shaft rod to facilitate obtaining a better shooting angle.

[0062] See also Figure 1 An insect repellent box body is provided on the top wall of the air inlet pipe 5, a control valve is installed through the inner wall of the insect repellent box body, a sachet is hung on the top wall of the insect repellent box body, camphor balls are placed inside the sachet, a through pipe is provided on the surface of the air inlet pipe 5, and an interception net 21 is installed inside the through pipe.

[0063] Specifically, the interception net 21 can prevent external foreign objects from entering the interior of the air inlet pipe 5, and the control valve is kept closed during the start-up of the driverless car. When the driverless car is in a braking or closed state, the control valve is opened, so that the volatile smell of the mothballs can enter the air outlet pipe 4 along the hose, thereby forming an insect repellent treatment on the surface of the camera housing 1, preventing mosquitoes from approaching the surface of the camera and shielding it, thereby ensuring the clarity of the camera shooting picture.

[0064] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
