DETAILED DESCRIPTION

[0043] In order to enable people in this technical field to better understand the solution of this application, the technical solution in the embodiment of this application will be clearly and completely described below in combination with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all of the embodiments.

[0044] Example 1

[0045] like Figure 1 、 2 As shown, this embodiment discloses a net post structure, which includes: a base 200, a pipe column 100, a walking mechanism, and a controller. A first camera 210 and a second camera 310 are provided on the base 200, and the first camera 210 and the second camera 310 are used to capture external environment information. The pipe column 100 is fixedly provided on the base 200 and is used to fix the net line 800. The walking mechanism is provided at the bottom of the base 200 and is used to move the entire net post structure. The controller is provided on the base 200 or the pipe column 100 (not shown in the figure), and is electrically connected to the first camera 210, the second camera 310, and the walking mechanism, respectively, and is used to control the movement of the walking mechanism according to the image information captured by the first camera 210 and the second camera 310.

[0046] During use, two net post structures are typically used in conjunction with each other, placed at predetermined locations on either side of the court. Signs can be posted at these locations, and the net cables 800 at either end of the net are secured to the tubular posts 100 of the two net post structures. During a match, if one of the net post structures deviates from its predetermined position due to being pulled or otherwise, the first and second cameras 210 and 310 capture images of the deviated position and upload them to a controller. After a series of processing, including image recognition, the controller controls the movement of the travel mechanism to return the entire net post structure to its predetermined position. This entire process requires no manual operation, improving work efficiency.

[0047] In a specific implementation, the second camera 310 can be used to capture an image of the positional information between the net post structure and a predetermined position on the court. For example, if the net post structure is pulled forward relative to the predetermined position due to external force, the second camera 310 captures the corresponding image, and the controller controls the movement of the running mechanism based on the image data, causing the net post structure to move backward. The first camera 210 can be used to capture an image of the positional information between the net post and another net post. For example, if the net post structure is deflected due to external force, the first camera 210 captures an angle between the net post and another net post. In this case, the controller controls the movement of the running mechanism based on the image information, causing the net post structure to move and return to its original position.

[0048] It should be noted that controller technology that uses image recognition to control the movement of the walking mechanism to move the device to a predetermined position is currently mature, as disclosed in patents such as CN201110053080.3 and CN201611201238.6. It also has real-world applications, such as in automated guided vehicles (AGVs). Therefore, this embodiment does not elaborate on the controller's control logic, software, etc., as they are not the core of the invention. The following details the hardware components of the post structure.

[0049] like Figure 3 、 4 As shown, the walking mechanism includes a front wheel mechanism 700 and a rear wheel mechanism 600; the front wheel mechanism 700 and the rear wheel mechanism 600 have the same structure, both including: a bridge 603, two drive motors 602, two rollers 601 and a steering drive assembly.

[0050] The bridge 603 is fixedly mounted on the bottom of the base 200, and has a mounting cavity for mounting a drive motor 602 at each end. The two drive motors 602 are respectively mounted in the mounting cavities at both ends of the bridge 603 via pins, so that the two drive motors 602 can swing with the pins as fulcrums. In addition, the two drive motors 602 are electrically connected to the controller, and their operation is controlled by the controller. The two rollers 601 are respectively mounted on the rotating shafts of the two drive motors 602 and driven to rotate by the drive motors 602. When the drive motor drives the rollers 601 to rotate, the entire net post structure can be moved. The steering drive assembly is connected to the two drive motors 602 and is used to drive the two drive motors 602 to swing to achieve steering. At the same time, the steering drive assembly is also electrically connected to the controller, and its operation is controlled by the controller.

[0051] The steering drive assembly includes a connecting rod 604 and a driver. The connecting rod 604 is hingedly connected to the two drive motors 602 at both ends; that is, each drive motor 602 is provided with a mounting block, and the ends of the connecting rod 604 are respectively mounted to the mounting blocks of the two drive motors 602 via pins, so that the ends of the side rod 604 are respectively hingedly connected to the two drive motors 602. Furthermore, the driver is connected to the connecting rod 604 and is used to drive the connecting rod 604 to swing. When the connecting rod 604 swings, it drives the two drive motors 602 to swing, thereby achieving steering. Similarly, the driver is also electrically connected to the controller, and its operation is controlled by the controller.

[0052] As an optional implementation of this embodiment, the driving component is an electric telescopic rod. When the electric telescopic rod is controlled to extend or retract, the electric telescopic rod can push the connecting rod 604 to swing, and then push the two driving motors 602 to swing, thereby achieving steering.

[0053] As another optional implementation of this embodiment, the driving element is a steering motor 607, which is connected to the connecting rod 604 via a gear and rack meshing mechanism. Specifically, a gear is mounted on the rotating shaft of the steering motor 607, and a rack is provided on the connecting rod 604. The gear and rack mesh together. When the steering motor 607 drives the gear in forward and reverse rotation, the gear drives the connecting rod 604 to swing, thereby driving the two drive motors 602 to swing, achieving steering.

[0054] As another optional implementation of this embodiment, Figure 4As shown, the drive component includes a connector 605, a steering motor 607, and a rocker arm 608. The connector 605 is mounted on the connecting rod 604 and has a waist-shaped connector hole 606 perpendicular to the connecting rod 604. One end of the rocker arm 608 is connected to the rotating shaft of the steering motor 607, and the other end is inserted into the waist-shaped connector hole 606. The steering motor 607 is electrically connected to the controller. With this structure, when the steering motor 607 drives the rocker arm 608 back and forth, the rocker arm 608 drives the connecting rod 604 to swing, thereby driving the two drive motors 602 to swing, achieving steering.

[0055] In a specific implementation, the base 200 can support a rod 300, and the second camera 310 is mounted on the rod 300. The rod 300 faces the other net post structure. This arrangement provides better support for the net post structure and prevents it from toppling. Furthermore, reinforcing ribs 500 are provided between the tubular column 100 and the base 200 to increase the strength of the net post structure.

[0056] Example 2

[0057] The net post structure of this embodiment is based on the embodiment 1, and it also includes a self-tightening mechanism 400. Specifically, the self-tightening mechanism 400 includes a wire take-up assembly provided on the base 200 and a tension detection assembly 460 provided on the pipe column 100. The wire take-up assembly and the tension detection assembly 460 are both electrically connected to the controller, such as Figure 3 shown.

[0058] Among them, Figure 3 As shown, the wire take-up assembly includes a tensioning motor 410 mounted on the base 200 and a wire take-up wheel 450 mounted on the rotating shaft of the tensioning motor 410 .

[0059] The tension detection assembly 460 can be installed on the outer wall or inside of the pipe string 100. In this embodiment, the tension detection assembly 460 is installed inside the pipe string 100. Figure 5As shown, the tension detection assembly 460 includes: a mounting frame 461, a mounting shaft 466, an extrusion block 462, a third wire pulley 463, a fifth wire pulley 464, and a spring 469. The mounting frame 461 is fixedly mounted inside the pipe column 100. The mounting shaft 466 is fixedly mounted on the mounting frame 461, and a rotatable fourth wire pulley 465 is mounted thereon. The extrusion block 462 is provided with a waist-shaped mounting hole 467, through which the extrusion block 462 is movably mounted on the mounting shaft 466; that is, the mounting shaft 466 passes through the waist-shaped mounting hole 467, thereby allowing the extrusion block 462 to be movably mounted on the mounting shaft 466. The third wire pulley 463 and the fifth wire pulley 464 are both mounted on the extrusion block 462 and are located on either side of the fourth wire pulley 465. Tension detectors 470 are fixed to both ends of the spring 469. One end of the spring 469 is connected to the wall of the waist-shaped mounting hole 467, and the other end is connected to the mounting shaft 466. In order to facilitate the fixing of the spring 469, as shown in FIG. Figure 6 、 7 As shown, the walls of the mounting shaft 466 and the waist-shaped mounting hole 467 each have a socket 468 formed therein, into which the ends of a spring 469 are inserted, respectively. Two tension detectors 470 are conventional tension sensors, both connected to a controller. Their detection signals are transmitted to the controller, which in turn controls the tensioning motor 410 to retract and extend the net string.

[0060] In addition, the tension detection assembly 460 further includes a first wire wheel 430 and a second wire wheel 440; the first wire wheel 430 is disposed at the lower end opening of the pipe string 100, and the second wire wheel 440 is disposed at the upper end opening of the pipe string 100. Figure 3 shown.

[0061] In a specific configuration, the tension detection assembly 460 is vertically distributed in the pipe string 100 , that is, the third wire pulley 463 , the fourth wire pulley 465 and the fifth wire pulley 464 of the tension detection assembly 460 are sequentially distributed from top to bottom.

[0062] like Figure 8As shown, during use, the end of the net cable 800 is sequentially wound around the second wire pulley 440, the third wire pulley 463, the fourth wire pulley 465, the fifth wire pulley 464, and the first wire pulley 430 before being reeled onto the take-up reel 450. Under normal conditions, the third and fifth wire pulleys 463, 464 exert pressure on the squeeze block 462, and the tension detected by the tension detector 470 is the same as the tension preset in the controller. When the net becomes slack during use, the tension detected by the tension detector 470 changes. The controller then controls the tensioning motor 410 to reel the net cable 800. When the tension detected by the tension detector 470 returns to the set value, the tensioning motor 410 stops. This automatically tensions the net, eliminating the need for manual operation and improving work efficiency. The controller in this embodiment can be used in conjunction with the controller in Example 1, or a separate controller can be used. Controllers that control motor operation based on detected tension values ​​are currently mature technologies, and will not be described in detail here.

[0063] As a preferred implementation of this embodiment, a wire guide tube 420 is provided at the bottom of the base 200. The network cable 800 passes through the wire guide tube 420 and is then reeled onto the reel 450. The wire guide tube 420 can prevent the network cable 800 from being accidentally entangled on the walking mechanism.

[0064] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0065] In addition, the above-mentioned specific embodiments are merely illustrative. Those skilled in the art may devise various solutions based on the disclosure of this utility model, and such solutions fall within the scope of disclosure and the scope of protection of this utility model.
