Description

Technical Field

[0002] Production safety is a crucial aspect of mine management, as safe operations directly determine the economic benefits of mining enterprises. Mine safety encompasses a wide range of issues, including safety management in high-risk areas such as working faces and tunnels, as well as safety management of transportation routes such as mountain roads and slopes. Currently, many mining areas experience problems such as potholes and loose roadbeds due to repeated driving by heavy vehicles and the effects of rain and snow. The ride for driverless mining trucks (hereinafter referred to as driverless mining trucks) is extremely bumpy, which places higher demands on the real-time perception and management of road conditions on driverless heavy-duty transportation routes in mining areas. Failure to address this issue can jeopardize the safe operation of driverless mining trucks.

[0003] Environmental perception technology is one of the key technologies in unmanned driving technology in open-pit mines. For the current mature intelligent perception solutions, it is necessary to use multiple sensors such as radar, cameras, and video cameras to achieve accurate, real-time, comprehensive and reliable perception of unmanned mining trucks and the environment.

[0004] Currently, most cameras on unmanned mining trucks are installed using rigid connections. Due to the unique and complex environment of open-pit mines, the roads are very bumpy and the on-site environment is quite harsh. Unmanned mining trucks experience significant vibrations during operation. Working in such an environment for extended periods can negatively impact the imaging quality and lifespan of the cameras. Furthermore, the rigid connection method for cameras also presents the problem of inconvenient angle adjustment on-site. Utility Model Content

[0026] The following will be combined with the appendix Figures 1 to 6 The present invention will be further described below.

[0027] Firstly, such as Figures 1 to 5 As shown, this utility model provides a camera mounting device for an unmanned mining truck, including a base plate 1, a rotating bracket 2, a camera mounting bracket 3, a first shock absorber 4, and a second shock absorber 5. The base plate 1 is used for fixed connection to the body of the unmanned mining truck. The rotating bracket 2 is disposed above the base plate 1 and rotatably connected to the base plate 1. A first limiting member 21 is provided between the base plate 1 and the rotating bracket 2 to lock their relative positions. The camera mounting bracket 3 is rotatably connected to the rotating bracket 2 and is used to mount the camera. A second limiting member 31 is provided between the rotating bracket 2 and the camera mounting bracket 3 to lock their relative positions. The first shock absorber 4 is disposed between the base plate 1 and the rotating bracket 2. The second shock absorber 5 is disposed between the rotating bracket 2 and the camera mounting bracket 3.

[0028] This invention achieves flexible angle adjustment and multiple shock absorption by setting a rotatable connection between the rotating bracket 2 and the base plate 1 and a first shock absorber 4, and a rotatable connection between the camera mounting bracket 3 and the rotating bracket 2 and a second shock absorber 5. This effectively reduces the vibration transmitted to the camera when the mining truck travels on bumpy roads, significantly improves the stability and clarity of image acquisition, and extends the service life of the camera. The structure also enables rapid adjustment and locking of the spatial angle of the camera mounting bracket 3 through the first limiting member 21 and the second limiting member 31, solving the problem of inconvenient adjustment in existing rigid connection methods.

[0029] In some implementations, such as Figure 1 As shown, the rotating bracket 2 and the base plate 1 are horizontally rotatably connected. The first shock absorber 4 includes a horizontal silicone pad, which is disposed between the base plate 1 and the rotating bracket 2.

[0030] This invention features a horizontally rotatable connection between the rotating bracket 2 and the base plate 1, allowing the camera to be flexibly adjusted at multiple angles in the horizontal direction. By incorporating a horizontal silicone pad as the first shock absorber 4, it effectively absorbs and disperses vibrations and impacts from the vehicle body while enabling horizontal rotational adjustment, significantly reducing image jitter caused by frequent turning and bumps of the mining truck. The horizontal silicone pad not only provides cushioning and shock absorption but also offers damping during rotation, enhancing the stability of the adjustment.

[0031] In some implementations, such as Figure 3 As shown, the base plate 1 has several evenly distributed fixing holes, and the rotating bracket 2 has several horizontal annular holes 22 that correspond to the fixing holes. The first limiting member 21 includes multiple connecting bolts and nuts. Each connecting bolt passes through the fixing holes on the base plate 1 and the horizontal annular holes 22 on the rotating bracket 2 in sequence, and is locked by the nut, thereby fixing the relative position between the base plate 1 and the rotating bracket 2. Each horizontal annular hole 22 is an arc-shaped elongated hole, allowing the rotating bracket 2 to rotate a certain angle in the horizontal plane around the vertical axis where the center of the horizontal annular hole 22 is located, and multi-angle position adjustment and tightening can be achieved by the bolts in different positions in the horizontal annular holes 22. This connection method has a simple and reliable structure and has high vibration resistance and anti-loosening ability. In this embodiment, there are four fixing holes and four horizontal annular holes 22.

[0032] This invention utilizes an adjustment structure that combines evenly distributed circumferential fixing holes with horizontal annular holes 22, along with bolts and nuts as the first limiting components 21. This enables rapid, multi-angle adjustment and reliable locking of the rotating bracket 2 in the horizontal plane, improving the convenience of adjusting the camera's horizontal orientation. This structure effectively resists continuous vibrations during mining operations, prevents camera position shift, ensures the stability of the image acquisition direction, and features strong overall rigidity and durability, making it suitable for long-term use under harsh working conditions.

[0033] In some implementations, such as Figure 1 As shown, the camera mounting bracket 3 and the rotating bracket 2 are vertically rotatably connected. The second shock absorber 5 includes at least one vertical silicone pad, which is disposed between the rotating bracket 2 and the camera mounting bracket 3. In this embodiment, the camera mounting bracket 3 and the rotating bracket 2 are vertically rotatably connected by a second limiting member 31. The vertical silicone pad and the horizontal silicone pad are positioned at different angles. The horizontal silicone pad is horizontally positioned and can buffer and dampen vertical vibrations, while the vertical silicone pad is vertically positioned and can buffer and dampen horizontal vibrations. By setting the vertical and horizontal silicone pads, multi-angle shock absorption can be achieved, further enhancing the shock absorption effect of the mounting device, ensuring image acquisition quality, and extending the life of the camera.

[0034] In some implementations, such as Figure 1 As shown, the rotating bracket 2 has a U-shaped structure, the camera fixing bracket 3 is set in the U-shaped groove of the U-shaped structure, and the second shock absorber 5 includes two vertical silicone pads set between the two sides of the camera fixing bracket 3 and the inner walls of the two side plates of the U-shaped structure.

[0035] This invention achieves stable and symmetrical support and enclosure of the camera mounting bracket 3 by setting the rotating bracket 2 into a U-shaped structure and accommodating the camera mounting bracket 3 within the U-shaped groove, while placing vertical silicone pads between the side walls and the mounting bracket. This dual-sided shock absorption layout effectively balances and absorbs impact and torsional loads from different directions, suppressing high-frequency shaking and lateral displacement of the camera under complex working conditions.

[0036] In some implementations, such as Figure 1As shown in the figure, both two side plates of the U-shaped structure are provided with a rotating shaft screw hole and a vertical annular hole 23, the rotating shaft screw hole is located at the center of the vertical annular hole 23, and the vertical annular hole 23 is an arc-shaped elongated hole. A rotating shaft screw 311 is provided at the rotating shaft screw hole, the rotating shaft screw 311 passes through the rotating bracket 2 and the vertical silicone pad and then is connected to the camera fixing bracket 3. A positioning screw 312 is provided at the vertical annular hole 23, the positioning screw 312 passes through the rotating bracket 2 and the vertical silicone pad and then is connected to the camera fixing bracket 3. After loosening the rotating shaft screw 311 and removing the positioning screw 312, the camera fixing bracket 3 can realize vertically rotatable connection with the rotating bracket 2 with the rotating shaft screw 311 as the rotating shaft. The camera fixing bracket 3 is also provided with a rotating shaft screw hole and a plurality of positioning screw holes, the plurality of positioning screw holes are evenly arranged at positions corresponding to the vertical annular hole 23, as Figure 2 shown in this embodiment, there are 5 positioning screw holes, and 3 positioning screws 312 are provided, and the specification of the positioning screw 312 is smaller than that of the rotating shaft screw 311.

[0037] The utility model realizes accurate and flexible adjustment and firm locking of the pitching angle of the camera fixing bracket 3 through the arrangement of the adjusting structure in which the rotating shaft screw hole cooperates with the vertical annular hole 23. The rotating shaft screw 311 serves as the rotation center, which ensures centering during the rotation process, and the vertical annular hole 23 provides a reliable path and limit for angle adjustment. The structure allows operators to quickly loosen screws for angle adjustment, and easily lock and fix the same, which improves the convenience of adjusting the pitching angle of the camera. The arrangement of the vertical silicone pad not only effectively isolates vibration transmission, but also enhances the damping and adjustment stability of the connecting part.

[0038] In some embodiments, as Figure 1 and Figure 4 shown, the camera fixing bracket 3 is of an "n"-shaped structure, made of stainless steel, and its top is provided with a plurality of camera mounting holes 32. The hole spacing between two adjacent camera mounting holes 32 is 25 mm, which is the standard hole spacing for industrial cameras, and can adapt to the installation of cameras of different specifications.

[0039] In some embodiments, as Figure 1 shown, the bottom plate 1 is of an "Ω"-shaped structure, made of carbon steel, and its surface is subjected to spray plastic treatment to achieve anticorrosion protection. The "Ω"-shaped structure of the bottom plate 1 consists of an upper mounting part and connecting parts connected to the lower parts of the left and right sides of the mounting part, and the width of the connecting parts is greater than the width of the mounting part, as Figure 4 shown, the structure of the bottom plate 1 is H-shaped in a top view, and by arranging connecting parts with a width much larger than that of the mounting part, the mounting stability of the bottom plate 1 can be further enhanced. The rotating bracket 2 is made of stainless steel and has a thickness of 6 mm.

[0040] In some embodiments, as Figure 5As shown, a shock-absorbing pad 6 is installed between the base plate 1 and the vehicle body for overall vibration damping. The camera mounting device for the unmanned mining truck is installed at the front of the vehicle body. This silicone pad is a thickened silicone pad, and its shape can be set according to actual needs. It can be rectangular or triangular pyramidal. When the camera mounting device for the unmanned mining truck needs to be set at a certain angle, a triangular pyramidal silicone pad can be used for installation adjustment. The base plate 1 is connected to the unmanned mining truck body by eight screws.

[0041] The screws and bolts in this embodiment are equipped with spring washers and flat washers, which are more conducive to ensuring the tightness of the connection, preventing loosening, and adapting to the bumpy working environment of unmanned mining trucks in the mine.

[0042] Secondly, such as Figure 6 As shown, this utility model provides an unmanned mining truck, including the aforementioned camera mounting device for unmanned mining trucks.

[0043] The unmanned mining truck provided by this utility model significantly improves the reliability and stability of the vehicle's environmental perception system by integrating the aforementioned camera mounting device. The mounting device's multiple shock absorption and multi-angle adjustment functions ensure that the onboard camera can continuously acquire clear and stable image information even under harsh working conditions of bumpy and vibrating mining trucks, providing high-quality and highly available visual data input for the unmanned driving control system. This not only enhances the accuracy of the mining truck's perception on complex paths, effectively improving operational safety and efficiency, but also, thanks to its excellent vibration resistance and durability, reduces the frequency of system downtime and maintenance costs caused by camera failure, providing an important guarantee for the long-term stable operation of the unmanned mining truck.

[0044] In summary, this invention, through the rotatable connection between the rotating bracket 2 and the base plate 1 and the first shock absorber 4, and the rotatable connection between the camera mounting bracket 3 and the rotating bracket 2 and the second shock absorber 5, achieves flexible angle adjustment and multiple shock absorption buffers for the camera. This effectively reduces the vibration transmitted to the camera when the mining truck travels on bumpy roads, significantly improves the stability and clarity of image acquisition, and extends the camera's service life. Furthermore, the structure, through the first limiting member 21 and the second limiting member 31, enables rapid adjustment and locking of the spatial angle of the camera mounting bracket 3, solving the problem of inconvenient adjustment in existing rigid connection methods.
