Combined with the adjustment mechanism and motor, it achieves multi-angle adjustment, ensuring comprehensive and accurate 3D visual panoramic monitoring of the vehicle's surrounding environment.

Description

Technical Field

[0001] This application belongs to the field of vehicle engineering technology, specifically a monocular 3D visual panoramic monitoring device adapted for installation on multiple vehicle models. Background Technology

[0002] A monocular 3D panoramic camera is a device that uses a single camera to capture two-dimensional images of the environment around a vehicle. Combined with computer vision algorithms (such as distortion correction, feature extraction, stereo matching, and depth estimation), it constructs a 360-degree three-dimensional panoramic environment model of the vehicle's surroundings. This allows for real-time perception of information such as the distance, orientation, and size of surrounding obstacles. It eliminates the need for multiple cameras; a single lens working with algorithms can achieve panoramic 3D monitoring. Forklifts and other industrial vehicles are typically equipped with monocular 3D panoramic cameras because forklifts operating in confined spaces like warehouses and workshops need to monitor the real-time positions of pedestrians, goods, and other equipment to avoid collisions. Monocular 3D panoramic cameras meet these basic three-dimensional environmental monitoring needs and are suitable for cost-sensitive industrial applications, especially for small and medium-sized forklifts or in relatively simple working environments.

[0003] The installation of existing monocular 3D panoramic cameras on industrial vehicles such as forklifts mostly relies on direct fixing with customized brackets and bolts. Due to the lack of a unified standard for the body structure of industrial vehicles such as forklifts, there are significant differences in aspects such as the cab top outline, guardrail layout, and space around the fork carriage. Therefore, it is usually necessary to design special brackets for different vehicle models, which results in poor versatility. In addition, the installation process requires on-site measurement, positioning and drilling of the vehicle body, and then fixing with multiple bolts. The whole operation is not only cumbersome, but also very time-consuming and labor-intensive. To address this, we provide a monocular 3D panoramic monitoring device that is compatible with installation on multiple vehicle models. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] refer to Figures 1-5As shown, a monocular 3D visual panoramic monitoring device adaptable to multiple vehicle models includes a bracket 1. Multiple heat dissipation grooves 16 are formed on the outer surface of the bracket 1. A mounting base 2 is provided on the front side of the bracket 1. A monocular 3D camera 3 is hinged inside the mounting base 2. A rotating shaft 9 is rotatably connected to the front side of the bracket 1. The front end of the rotating shaft 9 is fixed to the rear side of the mounting base 2. A limiting plate 10 is fixedly installed at the rear end of the rotating shaft 9. An external gear ring 11 is fixedly installed on the outer surface of the limiting plate 10. A second motor 12 is fixedly installed on the inner wall of the bracket 1. A pinion 13 is fixedly installed at the drive end, and the pinion 13 meshes with the outer gear ring 11. The heat dissipation groove 16 can effectively increase the heat dissipation area of ​​the bracket 1, accelerate the dissipation of internal heat, and avoid the performance of electronic components due to high temperature. The pinion 13 is driven to rotate by the motor 2 12, which drives the outer gear ring 11, the limit plate 10, and the rotating shaft 9 to rotate. This enables the horizontal rotation adjustment of the mounting base 2 and the monocular 3D camera 3, flexibly adjusts the monitoring angle, adapts to the field of view requirements of different working scenarios, and improves the comprehensiveness of monitoring.

[0023] refer to Figures 1-5 As shown, the outer surface of the mounting base 2 is provided with an adjustment mechanism 4 connected to the monocular 3D camera 3. The adjustment mechanism 4 includes a mounting groove 401, a protective housing 402, a rotating shaft 403, a first gear 404, a first motor 405, and a second gear 406. The mounting groove 401 is opened on the side of the mounting base 2. The protective housing 402 is fixedly installed inside the mounting groove 401. The rotating shaft 403 is fixedly installed on the outer surface of the monocular 3D camera 3. The end of the rotating shaft 403 away from the monocular 3D camera 3 extends into the interior of the protective housing 402. The first gear 404 is fixedly installed at the end of the rotating shaft 403 extending into the interior of the protective housing 402. The first motor 405 is fixedly installed on the inner wall of the protective housing 402. The drive end of the first motor 405 is fixedly installed with a gear 406. Gear 2 406 meshes with gear 1 404. The protective housing 402 protects internal components such as gear 1 404 and gear 2 406 from dust and debris, preventing them from affecting transmission accuracy. The motor 1 405 drives gear 2 406 to rotate, which in turn drives gear 1 404 and shaft 403 to rotate. This allows for vertical angle adjustment of the monocular 3D camera 3, which, in conjunction with horizontal rotation adjustment, enables the camera to flexibly cover monitoring areas at different heights and orientations, further improving the flexibility and accuracy of monitoring. The 3D camera and motor mentioned above are existing devices; this application only uses them without modifying their structure, and therefore will not elaborate further.

[0024] refer to Figures 1-5As shown, a connecting seat 5 is fixedly installed on the rear side of the bracket 1 by bolts. A sealing gasket 15 is provided on the side of the connecting seat 5 near the bracket 1. The sealing gasket 15 is located between the bracket 1 and the connecting seat 5. The sealing gasket 15 can enhance the sealing between the bracket 1 and the connecting seat 5, prevent moisture, dust and other substances from entering the device, protect the internal components, and at the same time, it can also alleviate the impact of vibration on the connection part to a certain extent, and improve the stability and service life of the device.

[0025] refer to Figures 1-5 As shown, a U-shaped bracket 6 is provided on the rear side of the connecting seat 5. Two mounting holes 14 are provided on the inner side wall of the U-shaped bracket 6. A positioning hole 7 corresponding to the U-shaped bracket 6 is provided on the rear side of the connecting seat 5. One end of the U-shaped bracket 6 is inserted into the interior of the positioning hole 7. A fixing mechanism 8 connected to the U-shaped bracket 6 is provided inside the connecting seat 5. By cooperating with the mounting holes 14, it is easy for personnel to fix the U-shaped bracket 6 to the body of different vehicle models with bolts, which is compatible with a variety of vehicle models. By cooperating with the positioning hole 7 and the U-shaped bracket 6, the connecting seat 5 and the U-shaped bracket 6 can be quickly positioned, which facilitates subsequent fixing and improves installation efficiency.

[0026] refer to Figures 1-5 As shown, the fixing mechanism 8 includes a horizontal plate 801, a plug rod 802, a connecting plate 803, a spring 804, and a limiting groove 805. Two horizontal plates 801 are fixedly installed inside the connecting seat 5, and a plug rod 802 is movably inserted through one side of each of the two horizontal plates 801. The end of the plug rod 802 away from the connecting plate 803 has an arc-shaped transition surface. The connecting plate 803 is fixedly installed at one end of the plug rod 802. The end of the connecting plate 803 away from the plug rod 802 extends to the outside of the connecting seat 5. A spring 804 is fixedly installed on the side of the connecting plate 803 away from the plug rod 802. A limiting groove 805 corresponding to the plug rod 802 is opened on one side of the U-shaped bracket 6. The plug rod 802 is positioned away from the connecting plate 803. One end of plate 803 is inserted into the inside of limiting groove 805; horizontal plate 801 provides stable support and guidance for insertion rod 802, ensuring smooth movement of insertion rod 802; through the arc-shaped transition surface of insertion rod 802, friction is reduced when U-shaped bracket 6 is inserted into positioning hole 7, making it easier for U-shaped bracket 6 to push insertion rod 802 to move. When U-shaped bracket 6 is in place, spring 804 pushes connecting plate 803 and insertion rod 802 to reset, so that insertion rod 802 is inserted into limiting groove 805, achieving quick locking and convenient installation. When disassembly is required, simply press connecting plate 803 to drive insertion rod 802 out of limiting groove 805. The operation is simple and greatly improves the efficiency of installation and disassembly.

[0027] The implementation principle of the monocular 3D visual panoramic monitoring device embodiment adapted to multiple vehicle models in this application is as follows: First, the user fixes the U-shaped bracket 6 to a suitable position on an industrial vehicle such as a forklift using bolts through the mounting holes 14 on its inner side wall. This completes the initial basic installation. When the user needs to install the main body of the device, the user first aligns the positioning hole 7 on the rear side of the connecting seat 5 with one end of the U-shaped bracket 6 and inserts it. During the insertion process, the U-shaped bracket 6 presses the arc transition surface of the insertion rod 802, causing the insertion rod 802 to drive the connecting plate 803 to move and compress the spring 804. When the U-shaped bracket 6 is fully inserted into the positioning hole 7, the spring 804 returns to its original position, pushing the insertion rod 802 into the limiting groove 805 of the U-shaped bracket 6, thereby achieving rapid fixation between the main body of the device and the U-shaped bracket 6.

[0028] During the operation of the monocular 3D camera, the vertical angle of the monocular 3D camera 3 can be adjusted through the adjustment mechanism 4. Specifically, motor 1 405 drives gear 2 406 to rotate, which in turn drives gear 1 404 and rotating shaft 403 to rotate, thereby adjusting the monitoring angle of the monocular 3D camera 3 in the vertical direction. At the same time, motor 2 12 drives pinion 13 to rotate, which in turn drives outer gear ring 11, limiting plate 10 and rotating shaft 9 to rotate, realizing the horizontal rotation of mounting base 2 and monocular 3D camera 3. This allows for flexible adjustment of the camera's monitoring field of view, ensuring comprehensive and accurate 3D visual panoramic monitoring of the vehicle's surrounding environment. When it is necessary to disassemble or maintain the device, simply press the connecting plate 803 to disengage the insertion rod 802 from the limiting groove 805, and the main body of the device can be removed from the U-shaped bracket 6. The operation is convenient and efficient.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
