Description

Technical Field

[0001] This utility model relates to the field of unmanned driving equipment technology in mining, specifically to a mine-use suspended unmanned multi-sensor device and a mining vehicle. Background Technology

[0002] With the continuous development of automation and intelligence in mining, unmanned mining trucks have become key equipment for improving the safety and efficiency of mining operations. In the specific scenario of mining areas, the autonomous driving system of mining trucks relies heavily on multiple sensors to accurately perceive and model complex working conditions in order to achieve reliable path planning and obstacle avoidance. These sensors typically need to be securely integrated into specific locations on the exterior of the vehicle, and the reliability, accuracy, and stability of their installation directly determine the quality of data acquisition for the entire perception system, thus affecting the overall performance of the unmanned driving system.

[0003] However, common installation solutions are mostly temporary fixations for single sensors or specific vehicle models, lacking modular and standardized integrated design. This results in cumbersome equipment installation, disassembly, and subsequent maintenance processes, making it difficult to meet the actual needs of rapid adaptation to different vehicle models and flexible equipment deployment. Furthermore, the harsh working environment of mine roads, with their bumpy and vibrating surfaces, poses a severe test to the durability and measurement accuracy of precision sensors. Existing installation structures often lack systematic vibration reduction design, failing to effectively isolate impacts and vibrations from the vehicle body. This can easily lead to misalignment of internal optical components or damage to electronic components, not only shortening equipment lifespan but also creating safety hazards such as data distortion and even system failure.

[0004] Therefore, there is an urgent need for a mine-use suspended unmanned multi-sensor device and a mining vehicle to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Firstly, see reference Figures 1-6This application provides an embodiment of a mine-use suspended unmanned multi-sensor device. The device includes an installation fixture 1, a front cover plate 2, a rear cover plate 3, a radar mechanism, and a shock-absorbing mechanism. The installation fixture 1 includes a base 11, an inclined mounting seat 12, and a welding seat 13. The base 11 and the inclined mounting seat 12 are fixedly connected, and the welding seat 13 is fixed to the inclined mounting seat 12. The welding seat 13 is used to fixably connect to the welding position of the mine vehicle. The installation fixture 1 has openings on both sides along the horizontal direction. The front cover plate 2 and the rear cover plate 3 are respectively fixed to the openings on both sides of the installation fixture 1 along the horizontal direction, forming a cavity with the installation fixture 1. The radar mechanism is fixed to the base 11, and the radar is located within the cavity. The shock-absorbing mechanism is located within the cavity, between the radar mechanism and the mounting base 11.

[0030] The mining suspended unmanned multi-sensor device provided in this application embodiment, by designing the mounting fixture 1 as a modular structure including a base 11, an inclined mounting seat 12, and a welding seat 13, can be stably installed at a specific position on the mining car body, and also simplifies the installation and maintenance process. The mounting fixture 1, together with the front and rear cover plates 3, forms a sealed accommodating cavity, providing effective protection for the internal radar mechanism. In addition, by setting a shock-absorbing mechanism between the radar mechanism and the mounting base 11, the adverse effects of the severe vibration and impact generated by the mining car driving under complex road conditions on the precision radar equipment can be significantly reduced, ensuring the stability and accuracy of the sensor installation position, improving the stability and reliability of data acquisition, and thus effectively guaranteeing the long-term stable operation of the mining unmanned driving system under harsh working conditions.

[0031] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting fixture 1 further includes a partition 4, which divides the accommodating cavity into a first mounting cavity and a second mounting cavity along the height direction. The radar mechanism includes a first radar 5 and a second radar 6. The first radar 5 is fixed to the partition 4 and is located in the first mounting cavity. The second radar 6 is fixed to the base 11 and is located in the second mounting cavity.

[0032] By adding a partition 4 to divide the accommodating cavity into an independent first mounting cavity and a second mounting cavity in the height direction, a layered layout of the first radar 5 and the second radar 6 in the vertical space is achieved. This not only optimizes the space utilization inside the tooling and allows multiple radar sensors to be integrated in a compact and orderly manner, but more importantly, it effectively avoids mutual interference between the scanning areas of different radars, ensuring the independence and accuracy of the detection data of each radar. In addition, the layered installation method also provides convenience for the individual debugging, maintenance or replacement of each radar, improving the maintainability of the system, thereby achieving a comprehensive improvement in the performance and reliability of the sensing system within a limited space.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the shock absorption mechanism includes a first shock absorption component 7, which includes a radar mounting base and a first shock absorber 73. The radar mounting base includes a radar mounting plate 71 and a shock absorber mounting plate 72, which are fixedly connected. The radar mounting base composed of the radar mounting plate 71 and the shock absorber mounting plate 72 has an L-shaped cross-section. The first radar 5 is fixed to the radar mounting plate 71, and the first shock absorber 73 is fixed to the bottom of the shock absorber mounting plate 72. The other end of the first shock absorber 73 is fixedly connected to the partition plate 4.

[0034] By designing the radar mounting base with an L-shaped cross-section, the radar mounting plate 71 for mounting the first radar 5 and the damping mounting plate 72 for connecting the first damping component 73 are integrated into a rigid structure, making the overall installation of the first radar 5 more stable and compact. Furthermore, by placing the first damping component 73 at the bottom of the damping mounting plate 72, vibrations and impacts from the base 11 can be effectively buffered and absorbed by the first damping component 73 before being transmitted to the first radar 5. In addition, the L-shaped layout allows for optimized configuration of the first damping component 73 and the first radar 5 within a limited space, significantly reducing the adverse effects of vibration on the measurement accuracy of the first radar 5 under complex operating conditions, improving the reliability of the sensing system, and greatly extending the service life of the first radar 5.

[0035] like Figure 1 and Figure 5 As shown, in some embodiments, the damping mechanism includes a second damping component 8, which includes a first support column 81, a second support column 82, and a second damping element 83. The first support column 81 and the second support column 82 are both fixed to the bottom of the second radar 6. The bottom of the first support column 81 and the bottom of the second support column 82 are both provided with the second damping element 83, and the other end of the second damping element 83 is fixed to the base 11.

[0036] By configuring an independent second shock-absorbing component 8 for the second radar 6, using a first support column 81 and a second support column 82 fixed to the bottom of the radar, and setting a second shock-absorbing component 83 connected to the base 11 at the bottom of each support column, a stable and adjustable support effect is constructed for the second radar 6. This effectively isolates and attenuates the vibration of the second radar 6 itself during operation as well as the impact from the mine car, significantly reducing the interference of vibration on the precision optical components inside the second radar 6, ensuring the stability and measurement accuracy of the data acquisition of the second radar 6, and extending the service life of the second radar 6 under harsh working conditions.

[0037] In this embodiment, the first support column 81 and the second support column 82 have different lengths. The operator can use the first support column 81 or the second support column 82 according to different situations. Of course, in other embodiments, the first support column 81 and the second support column 82 can also adopt a telescopic structure, which can greatly save costs and enable precise adjustment of the height of the second radar 6.

[0038] like Figure 1 As shown, in some embodiments, the front cover plate 2 is provided with a first acquisition port 21 and a second acquisition port 22. The first acquisition port 21 is corresponding to the first radar 5, and the second acquisition port 22 is corresponding to the second radar 6.

[0039] By opening a first acquisition port 21 and a second acquisition port 22 on the front cover plate 2, which are precisely corresponding to the first radar 5 and the second radar 6 respectively, it is possible to ensure unobstructed penetration of the detection beams of the first radar 5 and the second radar 6 and achieve accurate scanning of the external environment. At the same time, the front cover plate 2 itself provides effective physical protection for the sensors of the first radar 5 and the second radar 6, avoiding direct damage caused by rain, dust and accidental collisions. It takes into account both the functionality of the radar detection and sensing system and the protection of the first radar 5 and the second radar 6, so that the first radar 5 and the second radar 6 can still perform at their best under the state of full protection, significantly improving the adaptability and reliability of the equipment in the harsh mining environment.

[0040] like Figure 1 and Figure 6 As shown, in some embodiments, the rear cover plate 3 has a first wire passage 31 and the partition plate 4 has a second wire passage 41. Both the first wire passage 31 and the second wire passage 41 are provided with sealing bushings.

[0041] By opening corresponding cable passages on the partition plate 4 and the rear cover plate 3 and installing sealing bushings, a neat and safe centralized wiring path is provided for cables connecting different installation cavities, effectively avoiding messy tangling of cables inside the enclosure. Furthermore, by installing sealing bushings at the first cable passage 31 and the second cable passage 41, the sealing performance at the cable passages is ensured, effectively preventing external rainwater, dust, and other contaminants from entering the accommodating cavity through cable gaps. This ensures neat wiring and ease of maintenance while significantly improving the overall protective effect and long-term operational reliability of the sensing equipment installation fixture 1 in harsh mining environments.

[0042] like Figure 1 and Figure 2As shown, in some embodiments, the mounting fixture 1 has a first slot and a second slot respectively provided at the openings on both sides along the horizontal direction. The front cover plate 2 has a first snap-fit ​​member on the side near the mounting fixture 1, which snaps into the first slot. The rear cover plate 3 has a second snap-fit ​​member on the side near the mounting fixture 1, which snaps into the second slot.

[0043] By setting a first and a second locking groove at the openings on both sides of the mounting fixture 1, and by setting corresponding first and second locking components on the front cover plate 2 and rear cover plate 3, rapid positioning and locking fixation between the cover plate and the main fixture are achieved. The locking structure greatly simplifies the installation and disassembly process, allowing for pre-fixing or disassembly of the cover plate without tools. This significantly facilitates daily inspection, maintenance, and cleaning of internal components by staff. Simultaneously, the locking mechanism ensures the tightness and accuracy of the connection between the cover plate and the main fixture, guaranteeing the integrity of the protective shell and effectively preventing protective failure due to loose connections under vibration conditions.

[0044] In addition, in this embodiment of the application, in order to ensure the stable fixation between the front cover plate 2 and the rear cover plate 3 and the mounting fixture 1, after the first snap-fit ​​and the second snap-fit ​​are snapped and fixed with the first snap-fit ​​groove and the second snap-fit ​​groove, they are further fixed by bolts, thereby further improving the fixing effect between the front cover plate 2 and the rear cover plate 3 and the mounting fixture 1.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, a damping mechanism is also included, which is disposed between the welding seat 13 and the inclined mounting seat 12.

[0046] By adding a damping mechanism between the welding seat 13 and the inclined mounting seat 12, a three-level vibration reduction barrier is constructed from the vehicle body to the first radar 5 and the second radar 6. On the one hand, it can effectively filter and buffer the most severe low-frequency large-amplitude impacts from the mine car at the source of vibration transmission, significantly reducing the vibration energy transmitted to the entire mounting fixture 1 and its internal first radar 5 and second radar 6. The damping mechanism works synergistically with the vibration reduction measures of the dedicated first damping component 7 and second damping component 8 of the internal first radar 5 and second radar 6 to construct a multi-level, systematic vibration reduction protection system, thereby more comprehensively ensuring the measurement accuracy, working stability and service life of the sensing equipment under extremely harsh road conditions.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, a temperature control system is also included, which includes a fan and a temperature sensor disposed in the accommodating cavity. The temperature sensor is used to monitor the temperature inside the accommodating cavity and control the fan to turn on or off according to the temperature inside the accommodating cavity.

[0048] By setting up a temperature control system consisting of a temperature sensor and a fan, the internal temperature of the accommodating cavity can be monitored in real time and the fan can be automatically started and stopped. This enables intelligent adjustment of the internal temperature of the accommodating cavity, effectively solving the problem of internal temperature accumulation caused by sunlight exposure or the heat generated by the equipment itself when the sealed tooling is working outdoors for a long time. Through forced air circulation and heat dissipation, the cavity temperature is maintained within the suitable operating temperature range of the first radar 5 and the second radar 6, preventing the performance degradation, data drift or premature aging of the first radar 5 and the second radar 6 caused by high temperature. This significantly improves the environmental adaptability and long-term operational reliability of the first radar 5 and the second radar 6 under high temperature conditions.

[0049] Secondly, an embodiment of this application provides a mining vehicle, including the mining suspended unmanned multi-sensor device as described above, and also includes an inclined ladder, with a welding base 13 fixedly connected to the inclined ladder.

[0050] The mining truck provided in this application embodiment fully utilizes the open field of vision of the area by installing and fixing the mine-mounted unmanned multi-sensor device as a whole on the inclined ladder of the mining truck. This provides an unobstructed optimal detection environment for the first radar 5 and the second radar 6. At the same time, this suspended installation method firmly connects the sensing device to the vehicle body, ensuring the installation rigidity and positional stability of the device during vehicle operation. This enables the mining truck to obtain surrounding environmental information in real time and accurately in complex mining environments, thereby significantly improving the environmental perception capability, operational safety, and operational reliability of the unmanned mining truck.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
