DETAILED DESCRIPTION

[0039] The present application provides a security unmanned patrol vehicle, the structure and function of which are realized through the cooperation of multiple components. The specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings. Figure 1 The overall structure of the security unmanned patrol vehicle of the present application is shown in the figure, Figure 2 The overall structure of the security unmanned patrol vehicle of the present application is shown in the figure, Figure 3 The overall structure of the bearing table and related components of the present application is shown in the figure, which includes vehicle body frame 1, telescopic drive device 2, bearing table 3, first transmission mechanism, second transmission mechanism, detection mechanism, and sensing mechanism, etc.

[0040] The vehicle body frame 1 is the basic structure of the entire patrol vehicle, the top of which is provided with an openable and closable roof mechanism, and the bottom of which is provided with a drive module. The openable and closable roof mechanism and the drive module are usually prior art, and the drive module realizes the moving function of the entire vehicle. The telescopic drive device 2 is arranged inside the vehicle body frame 1, and the output end thereof is connected with the bearing table 3. The telescopic drive device 2 includes an electric push rod and a guide rod. The electric push rod is fixed inside the vehicle body frame 1, and the guide rod is fixedly connected with the bearing table 3 through bolts, so as to ensure the stability of the bearing table 3 during the telescopic process. The bearing table 3 is provided with a sliding rail for mounting the first transmission mechanism and the second transmission mechanism.

[0041] The first transmission mechanism includes a first threaded rod 4 and a first drive motor 5. The two ends of the first threaded rod 4 are fixed on the bearing table 3 through bearing seats. The first drive motor 5 is specifically a stepping motor, and the output shaft thereof is connected with one end of the first threaded rod 4 through a shaft coupling.

[0042] The second transmission mechanism includes a second threaded rod 6 and a second drive motor 7. The two ends of the second threaded rod 6 are fixed on the bearing table 3 through bearing seats. The second drive motor 7 is specifically a servo motor, and the output shaft thereof is connected with one end of the second threaded rod 6 through a shaft coupling.

[0043] The detection mechanism includes multiple sliding plates 8, which are slidably connected to the support platform 3. The sliding plates 8 are internally threaded with internal threads that match the first threaded rod 4, allowing the sliding plates 8 to move axially when the first threaded rod 4 rotates. A lifting bracket 9 is fixed to the sliding plates 8. A rotating outer frame 10 is located at the top of the lifting bracket 9. A rotating inner frame 11 is rotatably installed inside the rotating outer frame 10. One end of the rotating inner frame 11 extends out of the rotating outer frame 10 and is connected to a ring gear 12. A spiral track 13 is provided on the surface of the rotating inner frame 11, which cooperates with the adjustment mechanism.

[0044] The sensing mechanism includes a mobile base 15, which is slidably connected to the support platform 3. Internally, the mobile base 15 is provided with internal threads that match the second threaded rod 6, enabling the mobile base 15 to move axially as the second threaded rod 6 rotates. A telescopic rod 16, specifically an electric push rod, is mounted on the top of the mobile base 15. A laser distance measuring device 17 is mounted on its output end. The laser distance measuring device 17 is bolted to the top of the telescopic rod 16.

[0045] The adjustment mechanism includes multiple adjustment rods 18, which slide within transverse slots 19 on the rotating outer frame 10. A driver block 20 is fixed to the bottom of the adjustment rods 18 and engages with the spiral track 13. When the rotating inner frame 11 rotates, the driver block 20 moves along the spiral track 13, thereby driving the adjustment rods 18 to slide left and right along the transverse slots 19. A support arm 21 is fixed to the surface of the adjustment rod 18 and connected to the camera device 14 via a connecting rod.

[0046] A guide groove is provided on the lifting bracket 9 , and a guide plate is fixed to the outside of the rotating outer frame 10 . The guide plate is embedded in the guide groove, so that the rotating outer frame 10 can rotate along the guide groove.

[0047] The system also includes a linkage mechanism, located on one side of one of the lifting brackets 9 and secured to the lifting bracket 9 via a mounting bracket 23. Mounted on the mounting bracket 23 is a dual-axis driver 24, comprising two output shafts. One of the output shafts is connected to a first transmission shaft 25, the end of which, remote from the dual-axis driver 24, is connected to a first gear 251. The other output shaft is connected to a second transmission shaft 26, which is provided with a transmission sleeve 27, one end of which is connected to a second gear 28. A limiting rod is provided on the transmission sleeve 27 for limiting the position of the second gear 28. The end of the second transmission shaft 26, remote from the dual-axis driver 24, extends into the interior of the transmission sleeve 27, and the second transmission shaft 26 and transmission sleeve 27 are both rotationally and slidingly connected. The first gear 251 and the second gear 28 respectively mesh with the two ring gears 12, thereby achieving synchronous drive of the two detection mechanisms.

[0048] A positioning hole is provided on the surface of the lifting bracket 9, and a positioning screw 29 is provided on one side of the lifting bracket 9. One end of the positioning screw 29 is provided with an anti-slip groove, and the other end of the positioning screw 29 is provided with a knob. The positioning screw 29 is connected to the positioning hole by a thread.

[0049] The control module 30 is located on one side of the support platform 3 and is electrically connected to the telescopic drive device 2, the first drive motor 5, the second drive motor 7, the camera 14, the laser rangefinder 17, and the dual-axis driver 24 via wires. The control module 30 includes a main control chip, a power management unit, and a communication module. The main control chip is connected to each drive unit and actuator via signal lines to coordinate the operation of these components. The power management unit is a lithium battery pack, which is connected to each power-consuming component via wires. The communication module is connected to a remote monitoring center via a wireless network for real-time data transmission.

[0050] In practice, the unmanned patrol vehicle's workflow is as follows: First, the drive module activates, driving the vehicle frame 1 to move to the target area. Upon reaching the designated location, the retractable roof mechanism opens, and the telescopic drive mechanism 2 activates, raising the support platform 3 to the predetermined height. Subsequently, the first and second drive motors 5 and 7 are activated, rotating the first and second threaded rods 4 and 6, respectively, thereby causing the sliding plate 8 and mobile base 15 to move axially along their respective threaded rods. The movement of the sliding plate 8 adjusts the position of the lifting bracket 9 and the rotating outer frame 10. The rotating inner frame 11 within the rotating outer frame 10 achieves angular adjustment through the interaction of the spiral track 13 and the adjustment mechanism, ultimately aligning the camera 14 with the target area. The movement of the mobile base 15 adjusts the position of the telescopic rod 16 and the laser rangefinder 17, which measures the target distance and transmits the data to the control module 30. Upon activation, the dual-axis drive 24 synchronously drives the two ring gears 12 via the first gear 251 and the second gear 28, thereby achieving coordinated angular adjustment of the two detection mechanisms. The control module 30 generates control instructions based on the received data and uploads the data to the remote monitoring center through the communication module to complete multi-target tracking and rapid response tasks.

[0051] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principles of the present invention are supplemented below in combination with specific application scenarios.

[0052] In the actual operation process of the security unmanned patrol vehicle, first of all, the driving module drives the vehicle body frame 1 to move to the target area as a whole. After reaching the specified position, the vehicle top opening and closing mechanism can be opened, and then the control module 30 sends out instructions to start the telescopic driving device 2 to push the carrying table 3 to rise to a predetermined height in the vertical direction. In this process, the electric push rod, as the core component of the telescopic driving device 2, has its output end connected with the carrying table 3 through bolts, ensuring the stable rising of the carrying table 3.

[0053] Subsequently, the first driving motor 5 starts to rotate the first threaded rod 4. The first threaded rod 4 is fixed on the carrying table 3 through a bearing seat, and the sliding plate 8 is internally provided with an inner thread matched with the first threaded rod 4, so that the sliding plate 8 can move axially under the rotating action of the first threaded rod 4. The movement of the sliding plate 8 drives the lifting bracket 9 to adjust the position, and the rotating outer frame 10 at the top of the lifting bracket 9 is displaced accordingly. The rotating inner frame 11 rotatingly arranged inside the rotating outer frame 10 is meshed with the first gear 251 of the linkage mechanism through the gear ring 12, and when the linkage mechanism is started, the first gear 251 drives the gear ring 12 to rotate, thereby driving the rotating inner frame 11 to change the angle. The spiral track 13 on the surface of the rotating inner frame 11 is used in cooperation with the adjusting mechanism, and the driving block 20 at the bottom of the adjusting rod 18 is embedded in the spiral track 13. With the rotation of the rotating inner frame 11, the driving block 20 moves along the spiral track 13, thereby driving the adjusting rod 18 to slide up and down along the transverse sliding groove 19. The adjusting rod 18 finally adjusts the angle of the camera device 14 through the support arm 21 and the connecting rod, so that it can quickly align the target area.

[0054] At the same time, the second driving motor 7 starts to rotate the second threaded rod 6. The moving base 15 on the second threaded rod 6 moves axially through threaded transmission, and the telescopic rod 16 installed at the top of the moving base 15 adjusts the position accordingly. The telescopic rod 16 is an electric push rod, and its output end is installed with a laser ranging device 17 for measuring the target distance and transmitting data to the control module 30. The data of the laser ranging device 17 provides accurate target distance information for the control module 30, thereby generating corresponding control instructions.

[0055] In the angle linkage adjustment process of the detection mechanism, the linkage mechanism plays a key role. The double-shaft driver 24 is connected with the first gear 251 and the second gear 28 through the first transmission shaft 25 and the second transmission shaft 26 respectively, and the first gear 251 and the second gear 28 are meshed with the two gear rings 12 respectively. When the double-shaft driver 24 is started, the first gear 251 and the second gear 28 synchronously drive the two gear rings 12 to rotate, thereby realizing the angle linkage adjustment of the two detection mechanisms. This design avoids the problem of low shooting angle adjustment efficiency caused by independent motor driving in the prior art, and improves the multi-target tracking capability.

[0056] In actual operation, the control module 30 coordinates the operation of the entire system by electrically connecting the various drive units and actuators. The main control chip generates control instructions based on received data and uploads this data to a remote monitoring center via the communication module, enabling multi-target tracking and rapid response. The power management unit, a lithium battery pack, is connected to the various power-consuming components via wires to ensure stable power supply to the system.

[0057] In summary, the present invention solves the problems of insufficient perception flexibility, lack of linkage control mechanism and poor structural compactness in the prior art by optimizing structural design and functional integration, while improving multi-target tracking capability and rapid response capability.
