[0029] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement.

[0031] In the process of detecting or locating targets through small radars, as well as setting up electronic fences, it is necessary to adjust the direction of the radar. In existing technologies, the radar is often installed on a multi-axis mount for detection. For portable radar systems, it is often installed on a gimbal system.

[0032] The pan-tilt is a very important part of the radar system. During use, the radar needs to be installed on the pan-tilt and the direction of the radar is controlled by the rotation of the pan-tilt. However, the existing pan-tilt often has a high center of gravity. After the radar is installed, the center of gravity will be further increased, which will cause it to shake or tip over easily when placed in a special environment, causing safety problems in use. In summary, in the prior art, the stability of the radar pan-tilt is poor.

[0033] See also Figure 1The utility model provides a pan-tilt structure 100, comprising a mounting platform 1, a rotating platform 2 and a first driving device 3; the rotating platform 2 is rotatably mounted to the upper end surface of the mounting platform 1 around an axis extending vertically, and the rotating platform 2 is used to install a radar; the fixed end of the first driving device 3 is mounted to the lower end surface of the mounting platform 1, and the driving end of the first driving device 3 is drivingly connected to the rotating platform 2 to drive the rotating platform 2 to rotate.

[0034] In the pan-tilt structure 100 provided by the utility model, the rotating platform 2 and the first driving device 3 are respectively arranged on the upper and lower sides of the mounting platform 1, so that the center of gravity of the entire pan-tilt structure 100 is biased downward, avoiding that the rotating platform 2 and the first driving device 3 are both on the upper end surface of the mounting platform 1, causing the center of gravity of the pan-tilt structure 100 to be on the upper side of the mounting platform 1, avoiding that the center of gravity is completely on the upper end of the mounting platform 1 after the radar is installed, preventing the mounting platform 1 from tipping over when it is placed, ensuring the safety of the radar, and facilitating the use of the pan-tilt structure.

[0035] Furthermore, the pan-tilt structure 100 further includes a mounting bracket 4, which is mounted on the rotating platform 2 by rotating around a horizontal axis, and a mounting portion is formed on the mounting bracket 4, and the mounting portion is used to mount the radar. In this embodiment, the mounting bracket 4 that rotates around a horizontal direction is provided on the rotating platform 2, so that the radar can also adjust the pitch angle after being installed on the rotating platform, which is convenient for adjusting the direction of the radar and facilitating the use of the pan-tilt structure.

[0036] It should be noted that there are many ways to rotatably mount the mounting bracket 4 on the rotating platform 2, such as the matching of the shaft hole, so that the mounting bracket 4 is rotatably mounted on the rotating platform 2, and no specific limitation is made here.

[0037] In addition, the mounting portion has multiple implementations, such as bolting the radar by means of bolting holes and bolts.

[0038] Specifically, in this embodiment, a card slot is formed on the mounting bracket 4, and the mounting portion includes the card slot. The radar is connected via the card slot, which is convenient for installation and disassembly, and is convenient for the rapid disassembly and use of the pan-tilt structure.

[0040] Furthermore, a receiving cavity is formed on the rotating platform 2, and the second driving device 5 is installed in the receiving cavity, so as to protect the second driving device.

[0041] It should be noted that the second driving device has multiple implementation modes. In this embodiment, the second driving device 5 includes a stepping motor, and the output shaft of the stepping motor drives the mounting bracket 4 to rotate.

In this embodiment, the chip holder 6 is provided to facilitate mounting the control chip, so as to facilitate controlling the operation of the first driving device, or controlling a radar on the pan-tilt structure 100.

Specifically, the first driving device 3 includes a driving motor, so as to control the rotation of the rotating platform, and has a simple structure without the need to set other motion steering structures.

[0044] Furthermore, the mounting platform 1 is provided with a through hole; the output shaft of the driving motor is passed through the through hole and is driven and connected to the rotating platform 2.
