[0002] The cameras in unmanned mining trucks play a vital role in the vehicle's autonomous navigation and safe operation. The cameras capture images of the vehicle's surroundings, including road conditions, obstacles, other vehicles, pedestrians, etc., providing visual input for the unmanned driving system. Through image processing and computer vision technology, the cameras identify static and dynamic obstacles on the road and distinguish between different object types (such as vehicles, pedestrians, animals, etc.), ensuring the safe operation of the vehicle in complex environments, thereby achieving efficient and safe autonomous operation.

[0003] In existing technologies, unmanned mining trucks often face the problem of dust in the mine blocking the camera during driving. Dust will adhere to the camera lens, which may cause blurred images and affect the accuracy of image processing algorithms. Limited field of view and degraded image quality will increase the risk of system misjudgment, which may cause the vehicle to make incorrect driving decisions. This problem is likely to have a serious impact on the vehicle's autonomous navigation and safe operation. Utility Model Content

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example

[0030] Reference Figures 1-6 , is an embodiment of the present utility model, which provides a dust removal mechanism for an unmanned mining truck camera, including an imaging component 100, a driving component 200 and a cleaning component 300, which can drive a scraper 306 to perform intermittent reciprocating motion to achieve the effect of intermittent cleaning of the surface of the transparent glass 104.

[0031] The imaging assembly 100 includes a camera housing 102 fixedly mounted on the top of the unmanned mining truck T, a transparent glass 104 fixedly mounted on the inner surface of the camera housing 102, and a lens 105 fixedly arranged on the inner side of the camera housing 102;

[0032] It should be noted that the unmanned mining truck T uses a variety of sensors such as cameras, lidar, radar, ultrasonic sensors, inertial measurement units, and high-precision positioning systems to perceive the surrounding environment and build an environmental model. It then makes decisions and plans through technologies such as environmental modeling, path planning, and behavioral decision-making. It then uses execution control systems such as the electronic control unit (ECU), wire-controlled steering, and wire-controlled braking to achieve precise control of the vehicle. It also communicates with the remote monitoring system through V2X communication technology to ensure real-time data transmission and remote control. Finally, the safety and reliability of the system are guaranteed through redundant systems, fault diagnosis and self-repair mechanisms, and emergency stop mechanisms. The integrated application of this series of technologies enables unmanned mining trucks to achieve autonomous navigation, precise operation, and efficient transportation in complex mining environments, thereby improving the efficiency and safety of mine operations.

[0033] A dust cleaning assembly 300 is provided on the outside of the camera housing 102 and corresponds to the transparent glass 104. The dust cleaning assembly 300 is used to remove dust from the surface of the transparent glass 104. The dust cleaning assembly 300 includes a scraper 306.

[0034] The driving assembly 200 is disposed on the inner side of the camera housing 102 and assembled with the scraper 306 . The driving assembly 200 is used to drive the scraper 306 to perform reciprocating motion on the surface of the transparent glass 104 .

[0035] The camera bracket 101 is used to provide a solid fixing point for the camera housing 102, so that the camera is firmly mounted in a suitable position in the vehicle to ensure that the camera will not become loose or fall off due to vibration or bumps during driving. The camera bracket 101 also allows the angle of the camera housing 102 to be adjusted to ensure that the camera can cover the required field of view, whether it is the road conditions ahead, the side environment or the rear situation, and can be adjusted as needed;

[0036] Among them, the battery 103 is used to provide power to the motor 201. The battery 103 adopts a 12V 100Ah lead-acid gel battery that can provide long-term power supply for the drive component 200. The transparent glass 104 prevents dust, water droplets and other pollutants from directly contacting the lens 105, ensuring that the lens 105 can work normally under harsh conditions such as complex environments such as mines. The lens 105 is used to focus the light entering the camera onto the image sensor to form a clear image. By adjusting the focal length, the image is ensured to be clear and sharp, and the field of view is changed by adjusting the focal length. The imaging component 100 is a prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0037] Specifically, the driving assembly 200 includes a motor 201 adapted to be installed in the camera housing 102, a connecting plate 203 fixed to the output end of the motor 201, a driving block 204 fixedly connected to the end of the connecting plate 203, a bar-shaped hinge block 205 hinged to the outer surface of the driving block 204, a rack 206 fixedly connected to the outer surface of the bar-shaped hinge block 205, a fixing block 207 fixed to the inner side of the camera housing 102 and sleeved on the outer surface of the rack 206, a gear 208 meshing with the outer surface of the rack 206, and a connecting shaft 209 rotatably connected to the inner side of the camera housing 102 for assembling the gear 208.

[0038] The outer surface of the rack 206 is in sliding contact with the inner wall of the fixing block 207 , and the outer surface of the fixing block 207 is fixed at the connection with the camera housing 102 .

[0039] It should be noted that turning on the motor 201 can drive the coupling 202 to rotate, so that the coupling 202 drives the connecting plate 203 to rotate synchronously, and the connecting plate 203 drives the driving block 204 to perform circular motion. The fixed block 207 limits the rack 206, so that the rack 206 limits the bar-shaped hinge block 205, so that the driving block 204 drives the bar-shaped hinge block 205 and the rack 206 to perform reciprocating linear motion, and then the rack 206 drives the gear 208 and the connecting shaft 209 to rotate back and forth;

[0040] Through the cooperation of the driving component 200 and the cleaning component 300, the surface of the transparent glass 104 can be intermittently cleaned, ensuring that the image captured by the camera is clearer and reducing image blur or distortion caused by impurities such as dust.

[0041] Specifically, the driving assembly 200 includes a motor 201 adapted to be installed in the camera housing 102, a connecting plate 203 fixed to the output end of the motor 201, a driving block 204 fixedly connected to the end of the connecting plate 203, a bar-shaped hinge block 205 hinged to the outer surface of the driving block 204, a rack 206 fixedly connected to the outer surface of the bar-shaped hinge block 205, a fixing block 207 fixed to the inner side of the camera housing 102 and sleeved on the outer surface of the rack 206, a gear 208 meshing with the outer surface of the rack 206, and a connecting shaft 209 rotatably connected to the inner side of the camera housing 102 for assembling the gear 208.

[0042] Furthermore, the cleaning assembly 300 includes a boss 301 fixedly mounted on the outer surface of the connecting shaft 209, a driving column 302 fixedly connected to one side of the boss 301, a brake wheel 303 fixedly installed on the outer surface of the connecting shaft 209, and a transmission shaft 304 rotatably connected to the inner side of the camera housing 102.

[0043] It should be further explained that the connecting shaft 209 drives the cam 301 to rotate synchronously, so that the cam 301 drives the driving column 302 and the brake wheel 303 to rotate back and forth. After the driving column 302 is rotated into the U-shaped groove of the driven wheel 305, it will drive the driven wheel 305 to rotate, so that the driven wheel 305 drives the transmission shaft 304 and the scraper 306 to rotate synchronously. After the driving column 302 rotates to a position where it is out of contact with the driven wheel 305, the brake wheel 303 limits the driven wheel 305 to prevent the driven wheel 305 from continuing to rotate due to inertia, thereby driving the scraper 306 to swing intermittently through the continuous reciprocating rotation of the driving column 302.

[0044] Furthermore, the dust cleaning assembly 300 further includes a driven wheel 305 fixedly sleeved on the outer surface of the transmission shaft 304 ; and a scraper 306 fixedly connected to the outer end surface of the transmission shaft 304 .

[0045] The transmission shaft 304 is rotatably connected to the inner surface of the camera housing 102 , and the motor 201 is fixedly installed in the inner cavity of the camera housing 102 .

[0046] Furthermore, the fixing block 207 is fixedly connected to the inner wall of the camera housing 102 , and the outer end surface of the connecting shaft 209 is fixedly mounted on the inner wall of the camera housing 102 via a bearing.

[0047] It needs to be explained that when the connecting shaft 209 rotates back and forth, it can drive the cam 301 to rotate synchronously, so that the cam 301 drives the driving column 302 and the brake wheel 303 to rotate back and forth. After the driving column 302 is rotated into the U-shaped groove of the driven wheel 305, it can drive the driven wheel 305 to rotate, so that the driven wheel 305 drives the transmission shaft 304 and the scraper 306 to rotate synchronously. After the driving column 302 rotates to a position where it is out of contact with the driven wheel 305, the brake wheel 303 limits the driven wheel 305 to prevent the driven wheel 305 from continuing to rotate due to inertia, thereby driving the scraper 306 to swing intermittently through the continuous reciprocating rotation of the driving column 302.

[0048] Specifically, a rubber strip is fixedly connected to the upper end of the scraper 306 , and the rubber strip is in contact with the outer surface of the transparent glass 104 .

[0049] Furthermore, a notch is formed on the surface of the driven wheel 305 for use with the driving column 302 , and arc grooves are formed on both sides of the notch for use with the brake wheel 303 .

[0050] Preferably, the outer surface of the rack 206 is in sliding contact with the inner wall of the fixing block 207 , and the outer surface of the fixing block 207 is fixed at the connection with the camera housing 102 .

[0051] When in use, the motor 201 is turned on to drive the coupling 202 to rotate, so that the coupling 202 drives the connecting plate 203 to rotate synchronously, and the connecting plate 203 drives the driving block 204 to perform circular motion. The fixed block 207 limits the rack 206, so that the rack 206 limits the bar-shaped hinge block 205, so that the driving block 204 drives the bar-shaped hinge block 205 and the rack 206 to perform reciprocating linear motion, and then the rack 206 drives the gear 208 and the connecting shaft 209 to rotate back and forth;

[0052] The connecting shaft 209 drives the cam 301 to rotate synchronously, so that the cam 301 drives the driving column 302 and the brake wheel 303 to rotate back and forth. After the driving column 302 is rotated into the U-shaped groove of the driven wheel 305, it drives the driven wheel 305 to rotate, so that the driven wheel 305 drives the transmission shaft 304 and the scraper 306 to rotate synchronously. After the driving column 302 rotates to a position where it is out of contact with the driven wheel 305, the brake wheel 303 limits the driven wheel 305 to prevent the driven wheel 305 from continuing to rotate due to inertia. The scraper 306 is driven to swing intermittently through the continuous reciprocating rotation of the driving column 302, and the surface of the transparent glass 104 is intermittently cleaned, ensuring that the image captured by the camera is clearer.

[0053] In summary, through the cooperation between the driving component 200 and the various components in the cleaning component 300, intermittent cleaning of the surface of the transparent glass 104 can be achieved. This method can not only ensure that the image captured by the camera is clearer and reduce image blur or distortion caused by impurities such as dust, but also significantly improve the accuracy of environmental perception of unmanned mining trucks. By adopting the intermittent cleaning method, when continuous monitoring is required, the scraper 306 can greatly reduce the time of blocking the camera's field of view, thereby ensuring that the continuous operation of the camera is not affected.
