Description
TECHNICAL FIELD
[0001] The utility model relates to laser radar technical field especially relates to a laser radar lens automatic wiper. BACKGROUND
[0002] In the process of using laser radar, it needs to scan through the lens. In the field, it needs to keep the cleanliness of the lens surface to ensure the accuracy of the radar when scanning. At present, the lens cleaning of laser radar generally uses exposed wiper to clean. But due to the harsh environment in the field, the wiper is very easy to be damaged. When the wiper is damaged and there are water drops on the lens surface, the radar scanning will be greatly affected. Therefore, a new wiper which is not easy to be damaged needs to be designed to clean the lens. SUMMARY
[0003] The utility model provides a laser radar lens automatic wiper which has simple structure and long service life.
[0004] The utility model employs the technical scheme, a laser radar lens automatic wiper is arranged in the inside of the upper cover of laser radar, the laser radar lens automatic wiper includes wiper, wiper motor, synchronous belt and wiper movement double track, the wiper is slidably connected on the wiper movement double track and is fixedly connected with the synchronous belt, the driven shaft is arranged on the wiper movement double track, the driven wheel is arranged on the driven shaft, the driving wheel is arranged on the output shaft of wiper motor, and the synchronous belt is matched between the driving wheel and the driven wheel.
[0005] The above scheme can be seen, by setting the wiper in the inside of the upper cover of laser radar, the structure of the wiper is avoided to be influenced by the harsh environment in the field, the service life of the wiper is guaranteed, and the lens is automatically cleaned by the driving of the wiper motor, the cleaning efficiency is improved, and the accuracy of radar scanning is guaranteed; And its simple structure, stable and reliable structure.
[0006] The wiper is used to clean the lens located below the inside of the upper cover, and a drainage groove is arranged on the periphery of the lens. As can be seen, through the setting of the drainage groove, the water scraped by the wiper can be drained in time, so that the water scraped in the process of moving back and forth is not brought back to the lens to cause invalid operation of the wiper.
[0007] A limit sensor is arranged on one side of the wiper motor, and the limit sensor and the wiper motor are electrically connected with the control panel in the laser radar. As can be seen, through the setting of the limit sensor, the moving position of the wiper can be sensed to prevent the wiper from colliding with the laser radar. BRIEF DESCRIPTION OF DRAWINGS

[0012] As shown in Figs. 1-4 A laser radar lens automatic wiper is arranged inside an upper cover 2 of a laser radar 1, and comprises a wiper 3, a wiper motor 4, a synchronous belt 5, and a wiper moving double track 6. The wiper 3 is slidingly fitted on the wiper moving double track 6 and fixedly connected with the synchronous belt 5. A driven shaft 7 is arranged on the wiper moving double track 6, and a driven wheel 8 is arranged on the driven shaft 7. A driving wheel 9 is arranged on an output shaft of the wiper motor 4, and the synchronous belt 5 is fitted between the driving wheel 9 and the driven wheel 8. The wiper 3 cleans a lens 10 located below the inside of the upper cover 2, and a drainage groove 11 is arranged on the periphery of the lens 10.
[0013] A limit sensor 12 is arranged on one side of the wiper motor 4, and the limit sensor 12 and the wiper motor 4 are electrically connected with a control board in the laser radar 1.
[0014] Finally, it needs to be emphasized that the above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
