[0017] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0018] Example 1

[0019] See also Figure 1-3 The present embodiment provides a camera gimbal structure for visual inspection in a high-precision requirement scenario, including a mounting plate 100, a connecting arm 120 is rotatably provided at the bottom of the mounting plate 100, a clamping arm 140 is rotatably provided at one end of the connecting arm 120, a detection mechanism 160 for visual inspection is rotatably provided on the clamping arm 140, the detection mechanism 160 includes a shell 210 rotatably provided on the clamping arm 140, a mounting cavity 220 is provided on the front end of the shell 210, a camera 230 is detachably provided inside the mounting cavity 220, a transparent protective cover 240 for protecting the camera 230 is provided outside the mounting cavity 220, and a cleaning mechanism 170 for cleaning the transparent protective cover 240 is also provided on the top of the clamping arm 140.

[0020] When the present embodiment is in use, the dust on the transparent protective cover 240 can be cleaned by driving the detection mechanism 160 to rotate and cooperate with the cleaning mechanism 170. The operation is simple and does not require manual regular cleaning. The transparent protective cover 240 is fixed in front of the camera, so that the camera has good protection measures.

[0021] In this embodiment, a first motor 110 for driving the connecting arm 120 to rotate is fixedly provided at the bottom of the mounting plate 100, a second motor 130 for driving the clamping arm 140 to rotate is fixedly provided on the connecting arm 120, and a third motor 150 for driving the detection mechanism 160 to rotate is fixedly provided on both sides of the clamping arm 140.

[0022] Through the above structure, when the angle of the camera needs to be adjusted, a larger angle can be adjusted compared to the prior art.

[0023] In this embodiment, the cleaning mechanism 170 includes a support arm 310 fixed on the top of the clamping arm 140, and a plurality of mounting grooves 320 are provided at the bottom of the support arm 310. Sliding columns are slidably provided inside the mounting grooves 320. A scraper 340 for cleaning the transparent protective cover 240 is fixed between the bottoms of the plurality of sliding columns, and a spring 330 for pressing the scraper 340 is fixed between the sliding column and the mounting groove 320.

[0024] Through the above structure, when the transparent protective cover 240 needs to be cleaned, the detection mechanism 160 rotates the cleaning mechanism 170 to clean the transparent protective cover 240, and the scraper 340 is pressed by multiple springs 330 to improve the cleaning effect of the transparent protective cover 240.

[0025] In this embodiment, arc strips 250 are fixedly provided on both sides of the housing 210, and a groove 260 is formed between the arc strip 250 and the outer wall of the housing 210, and inclined surfaces 270 are provided at both ends of the arc strip 250;

[0026] The two ends of the scraper 340 are in contact with the tops of the arc strips 250 on both sides respectively;

[0027] The grooves 260 are located at two sides of the installation cavity 220 , and the length of the grooves 260 is the same as the length of the long side of the installation cavity 220 .

[0028] Through the above structure, when the scraper 340 is not cleaning the transparent protective cover 240, the arc strip 250 pushes the scraper 340 upwards. At this time, when the angle of the camera 230 on the detection mechanism 160 is adjusted, the scraper 340 is separated from the outer wall of the detection mechanism 160. At this time, the spring 330 is compressed. When the transparent protective cover 240 needs to be cleaned, when the detection mechanism 160 rotates along the clamping arm 140 to the inside of the groove 260, the spring 330 releases the pressure to make the scraper 340 fit with the transparent protective cover 240. This can reduce the friction between the scraper 340 and the detection mechanism 160 when the scraper 340 is not cleaned, thereby increasing the service life of the scraper 340 and improving the cleanliness of the scraper 340, thereby improving the cleaning effect of the transparent protective cover 240.

[0029] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0030] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
