Compared with the existing pan-tilt support arm (the support arm of which mostly adopts a structure assembled by disassembled inner side plates, outer side plates, and end side plates), the first base 10, the support arm 20, and the second base 30 of the pan-tilt support arm disclosed in the embodiment are integrally formed. Moreover, the integrally formed support arm 20 is designed to be enclosed by an inner side plate 21, an outer side plate 22, and two end side plates 23. Therefore, the overall bending and torsion resistance of the support arm can be enhanced. The single-arm structure can also support a camera module with a large load. In addition, the first base 10, the support arm 20, and the second base 30 communicate with each other internally, which is conducive to the routing of signal lines. The antenna can also be arranged in the first base 10, the support arm 20, or the second base 30, thereby ensuring a good working environment for the antenna.

[0022] In some preferred embodiments, the first base 10, the support arm 20 and the second base 30 are integrally formed by using a polyamide fiber mixed with fiberglass material, a PC mixed with ABS material or a PVC material.

[0023] The pan-tilt support arm can be used to construct a two-axis pan-tilt, that is, the pan-tilt is provided with a yaw axis motor and a pitch axis motor. In some embodiments, the yaw axis motor can be disposed below the first base 10, and its rotor is connected to the first base 10, and the yaw control of the camera module is realized by driving the rotation of the first base 10; the pitch axis motor is installed in the second base 30, and its rotor is connected to the camera module, and the pitch control of the camera module is realized by driving the rotation of the camera module. It should be noted that the pan-tilt support arm can also be used to construct a three-axis pan-tilt, that is, the pan-tilt is further provided with a roll axis motor (Roll axis motor). In some embodiments, the roll axis motor can be installed in the mounting base of the camera module, and the roll control of the camera module is realized by driving the lens module of the camera module.

[0024] As shown in the attached drawings, in some preferred embodiments, the first connection transition part 25 between the inner side plate 21 and the top plate 11 and the second connection transition part 26 between the end side plate 23 and the top plate 11 are both designed as concave arc-shaped structures. In this way, the connection firmness between the support arm 20 and the first base 10 can be increased, and the bending and torsion resistance strengths of the overall support arm can be further enhanced.

[0025] Refer to Figure 1 , in this embodiment, a motor mounting plate 32 is formed in the middle of the motor mounting seat 31, which can be used for the installation and fixation of the pitch axis motor, thereby improving the convenience of motor installation.

[0026] Refer to Figure 2 , preferably, a first reinforcing rib part 40 is formed on the inner side surface of the first connection transition part 25.

The antenna is disposed in the pan-tilt support arm (it can be disposed at least at one of the first base 10, the support arm 20, and the second base 30), and the signal line passes through the accommodating cavity 24 of the support arm 20. For a pan-tilt camera using a two-axis pan-tilt, the signal line is led out from the imaging module, passes through the pitch-axis motor, then enters the first base 10 via the accommodating cavity 24, then passes through the yaw-axis motor, and finally is connected to the control board of the pan-tilt camera; for a pan-tilt camera using a three-axis pan-tilt, the signal line also passes through the roll-axis motor before being connected to the pitch-axis motor. Regarding the connection of the signal line to each functional component of the pan-tilt camera, it can be carried out using the prior art and will not be elaborated herein.

[0030] The pan-tilt camera can be provided with a plurality of antennas. At least one of the antennas is disposed at one side wall of the accommodating cavity 24, and the signal line is attached to the other side wall of the accommodating cavity 24.
