Thus, the motor assembly 40 can be controlled by the flexible circuit board 60, so that the pan/tilt/zoom camera structure 100 has three rotational degrees of freedom that can be rotated by the motor.

In the present embodiment, the pan/tilt head camera structure 100 further includes a guide 13, one end of the guide 13 is fixedly connected to the bracket 10, and the other end of the guide 13 is located on the side of the first motor 41 away from the bracket 10, that is, the other end of the guide 13 is suspended at the end of the first motor 41 away from the rotating shaft. The guiding member 13 may be a sheet metal member, one end of the guiding member 13 is fixed in the accommodating space 11 and passes through the through slot 12, and the other end of the guiding member 13 is suspended at one end of the first motor 41 far away from the rotating shaft.

Fig. 5 is a schematic structural view of the shaft support 34 according to the present invention.

In this embodiment, the supporting frame 30 includes a rotating base 33, a first supporting arm 31 and a second supporting arm 32, and the first supporting arm 31 and the second supporting arm 32 are respectively located at two sides of the rotating base 33 and are fixedly connected to the rotating base 33. The supporting frame 30 may be U-shaped, the rotating base 33 may be regarded as the bottom of the U-shape, and the first supporting arm 31 and the second supporting arm 32 may be regarded as two arms of the U-shape. The first support arm 31 and the second support arm 32 are used to support the terminal mount 50. The support bracket 30 further includes a shaft support 34, the shaft support 34 being mounted to the second support arm 32. The shaft support 34 corresponds to an extension of the second support arm 32, and the shaft support 34 is used to support one end of the terminal mount 50. The provision of the shaft support 34 may facilitate the installation of the terminal mounting member 50. The terminal mounting member 50 has one end to which the third motor 43 is mounted and the other end provided with a shaft portion 511, and the shaft portion 511 is coaxial with the rotation shaft of the third motor 43. The shaft portion 511 is rotatably coupled to the shaft support 34, and a bearing for supporting the shaft portion 511 may be provided on the shaft support 34. Thereby, the terminal attachment 50 can be rotated by the driving of the third motor 43, supported by the first support arm 31 and the shaft support 34. The second supporting arm 32 is provided with a wiring surface 321 parallel to the axis of the shaft portion 511, and the first branch 61 is sequentially attached to the periphery of the rotating base 33 and the wiring surface 321 and wound at least one turn around the shaft portion 511. Preferably, the first branch 61 is wound two turns around the shaft portion 511. Thus, during the rotation of the terminal installation member 50 driven by the third motor 43, the first branch 61 can reduce or increase the number of winding turns, thereby avoiding the disturbance of the rotation of the terminal installation member 50 due to disorder. As shown in fig. 5, preferably, the side of the shaft support 34 near the shaft portion 511 is provided with an annular groove 341 for receiving the first branch 61, and the outer side wall of the annular groove 341 is provided with a notch 342 for passing the first branch 61.

In the present embodiment, the pan-tilt camera structure 100 further includes a circuit board 70. The circuit board 70 is electrically connected to the third motor 43, the first branch circuit 61, and the camera 90, respectively. That is, the first branch circuit 61 is finally connected to the circuit board 70, and controls the third motor 43 and the camera 90, respectively, through the circuit board 70. It is to be understood that if the terminal fitting member 50 is not mounted with an electronic product, the product where the camera 90 is located does not need to be electrically connected to the circuit board 70.

In this embodiment, the terminal mounting member 50 may include an upper case 51 and a lower case 52, the upper case 51 and the lower case 52 are locked to form a receiving space 53, and a shaft portion 511 is provided at one end of the upper case 51. The camera 90, the third motor 43 and the circuit board 70 are all mounted in the housing space 53. The third motor 43 and the shaft portion 511 are respectively located at both ends of the terminal mounting member 50, and the shaft portion 511 is coaxial with the rotation shaft of the third motor 43. The shaft portion 511 is rotatably coupled to the shaft support 34, and a bearing for supporting the shaft portion 511 may be provided on the shaft support 34. Thereby, the terminal attachment 50 can be rotated by the driving of the third motor 43, supported by the first support arm 31 and the shaft support 34.

In some cases, a coaxial cable may also be used to connect the control circuit 91 to the motor assembly 40. Compared with a flexible circuit board, the coaxial cable has a smaller cross-sectional size, so that the design requirement of the structural member is simpler, but the cost of the coaxial cable is more expensive than that of the flexible circuit board. The flexible circuit board is more suitable for mass production. In this embodiment, the pan/tilt/zoom camera structure 100 employs the flexible circuit board 60, which can reduce the product cost and improve the mass-producibility of the product.
