DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4A data acquisition device for automatic driving comprises a support plate 1, a bottom plate 3 mounted above the support plate 1, a support seat 4 mounted on the bottom plate 3, a camera 10 mounted above the support seat 4 and a plurality of mounting blocks 2 mounted on the bottom surface of the support plate 1, one end of the camera 10 away from the support seat 4 is fixedly connected to a support block 12, the other side of the support block 12 is connected to a rotating mechanism, the other end of the rotating mechanism is connected to an arc plate 5, a side of the arc plate 5 close to the camera 10 is fixedly connected to a wiping pad 11, the inner side of the wiping pad 11 matches and abuts against the outer wall of the camera 10, a side of the bottom plate 3 away from the support plate 1 is fixedly connected to a water tank 6, the inner wall of the water tank 6 is connected to a water outlet mechanism, the output end of the water outlet mechanism passes through the water tank 6 and is connected to a transition component, the other end of the transition component is connected to an end of the arc plate 5 away from the rotating component.

[0023] The structure of the automatic driving data acquisition device in the utility model is similar to that of the existing automatic driving data acquisition device, such as a data acquisition device for visual image processing for automatic driving disclosed in the patent with publication number CN215706037U. Figures 1 to 4 As shown, when the autonomous driving vehicle is traveling on a road in rainy weather, the autonomous driving data acquisition device of the utility model can start the rotating mechanism through the internal controller of the autonomous driving vehicle or the external remote controller. After the rotating mechanism is started, the output end will drive the arc plate 5 and the wiping pad 11 to rotate on the outer wall of the camera 10. As the wiping pad 11 rotates, the rain adhering to the surface of the camera 10 can be scraped off, thereby preventing the rain from affecting the shooting picture of the autonomous driving vehicle.

[0024] If the autonomous driving vehicle is driving in non-rainy weather and there is a lot of dust in the air, it will also affect the normal shooting of the camera 10. At this time, the rotating mechanism and the water outlet mechanism inside the water tank 6 can be opened through the internal controller of the vehicle or the external remote controller. The water outlet mechanism can transport the cleaning liquid inside the water tank 6 to the curved plate 5, and then the surface of the camera 10 can be wetted. Then, driven by the rotating mechanism, the dust adhering to the surface of the camera 10 can be wiped off again by the wiping pad 11.

[0025] Special mention should be made here:

[0026] 1. The vehicle internal controller or external remote controller is a very mature technology at present, so it will not be described in detail.

[0027] 2. Current autonomous driving vehicles usually require a driver to sit in the driver's seat, ready to take over vehicle control when necessary; in addition, even if there is no personnel directly monitoring in the vehicle, many autonomous driving systems are equipped with remote monitoring functions, which can transmit vehicle status and driving data to the operation center in real time, and the remote operator monitors and intervenes to deal with abnormal situations when necessary. Therefore, when the monitor finds that the picture taken by the camera 10 is affected, the controller can be used to turn on the rotating mechanism and the water outlet mechanism; of course, a sensor or monitor with a detection function can also be directly installed on the camera 10, and the sensor or monitor can monitor the camera 10, without specific limitation.

[0028] Please refer to Figure 2 The water outlet mechanism includes a water pump 15 and a water outlet pipe 7. The outer wall of the water pump 15 is fixedly connected to the bottom surface of the inner wall of the water tank 6. The output end of the water pump 15 is fixedly connected to one end of the water outlet pipe 7. The other end of the water outlet pipe 7 passes through the water tank 6 and is connected to the transition component.

[0029] More specifically, when the surface of the camera 10 needs to be moistened, it is only necessary to turn on the switch of the water pump 15 through the controller. After the water pump 15 is started, the input end will draw water from the inside of the water tank 6 and discharge it from the outlet pipe 7 to the transition component, and then it can enter the interior of the arc plate 5 from the transition component.

[0030] Please refer to Figure 3 The transition component includes a support pipe 8 and a water inlet pipe 16. The bottom surface of the outer wall of the support pipe 8 is fixedly connected to the side of the support seat 4 away from the bottom plate 3. The other end of the support pipe 8 is fixedly connected to the outer wall of the camera 10 away from the support block 12. One end of the water inlet pipe 16 is fixedly connected to the outer wall of the lower end of the support pipe 8. The other end of the water inlet pipe 16 is fixedly connected to the end of the water outlet pipe 7 away from the water pump 15. The water outlet pipe 7, the water inlet pipe 16 and the support pipe 8 are internally connected. The end of the support pipe 8 close to the camera 10 is connected to the end of the arc plate 5 away from the rotating component.

[0031] More specifically, after the water pump 15 is started, the cleaning liquid inside the water tank 6 is transported to the support pipe 8 through the water outlet pipe 7 and the water inlet pipe 16 , and finally enters the curved plate 5 through the support pipe 8 .

[0032] Please refer to Figure 3 The outer wall of one end of the support tube 8 close to the camera 10 is rotatably connected with a connecting tube 9, a plurality of water outlets 801 are penetrated at the connection between the support tube 8 and the connecting tube 9, a connecting port 901 is formed on the inner wall of the connecting tube 9, a water storage cavity 501 is formed on the inner wall of the arc plate 5, and a plurality of wetting holes 502 are penetrated on one side of the arc plate 5 close to the wiping pad 11, and the water outlet 801, the connecting port 901, the water storage cavity 501 and the plurality of wetting holes 502 are connected.

[0033] More specifically, by providing a connecting tube 9, and providing a water outlet 801, a connecting port 901, a water storage chamber 501 and a plurality of wetting holes 502, the cleaning liquid entering the support tube 8 can be evenly transported to the wiping pad 11, so that the surface of the camera 10 can be more conveniently wetted and wiped.

[0034] Please refer to Figure 1 The inner walls of the plurality of wetting holes 502 are each provided with a one-way valve.

[0035] More specifically, by providing a one-way valve, it is possible to prevent sewage on the camera 10 from flowing into the arc plate 5, and even causing clogging of the wetting hole 502. It should be particularly noted here that the one-way valve here can be a valve, which is not specifically limited.

[0036] Please refer to Figure 4 A motor cavity 1201 is opened on a side of the support block 12 away from the camera 10 , and one end of the rotating mechanism is located in the motor cavity 1201 .

[0037] More specifically, by providing the motor cavity 1201, the rotating mechanism can be housed, the component can reduce the external space occupied by the rotating mechanism, and is relatively more beautiful.

[0038] Please refer to Figure 1-Figure 4 The rotating mechanism includes a cleaning motor 13 and a connecting block 14. The outer wall of the cleaning motor 13 is fixedly connected to the inner wall of the motor cavity 1201. The output shaft of the cleaning motor 13 passes through the connecting block 14 and is fixedly connected to the inner wall of the connecting block 14. The outer wall of the connecting block 14 is fixedly connected to the end of the arc plate 5 away from the water tank 6.

[0039] More specifically, when it is necessary to control the arc plate 5 and the wiping pad 11 to clean and wipe the surface of the camera 10, it is only necessary to turn on the cleaning motor 13 through the controller to drive the arc plate 5 and the wiping pad 11 to rotate through the output shaft, and then the obstructions on the surface of the camera 10 can be wiped off during the rotation.

[0040] Special mention should be made here:

[0041] 1. The cleaning motor 13 can be set as a forward and reverse motor, or a normal 360° rotating motor, without specific limitation.

[0042] 2. The cleaning motor 13 can be set to a rotation angle, for example, it stops after each rotation. If repeated cleaning is required, the cleaning motor 13 can be repeatedly operated. In this way, when the cleaning motor 13 stops, the arc plate 5 and the wiping pad 11 can be located behind the camera 10, thereby avoiding blocking the image of the camera 10.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
