Further, described conducting slip ring inside and horizontal bearing component internal all are provided with accurate steel ball.

Further, described conducting slip ring is installed in the Kong Weili of horizontal bearing assembly.

Further again, the soft metal steel is being twined in described lead outside.

Further again, described vertical rotation structure comprises vertical limiting tooth, vertical strap wheel and takes turns positive 90 in vertical strap and spend, the lonely degree that negative 30 degree places are provided with.Described limiting tooth is installed on the described radian.

Further, described vertical rotation structure comprises stretching pulley.

Further, described vertical rotation structure comprises the Z-axis bearing assembly.

Further again, vertical connection lead is equipped with in described Z-axis bearing assembly inside, connects vertical pcb board and movement.

Video camera of the present utility model is owing to adopted conducting slip ring that whole video camera rotated freely in 360 ° of scopes.Simultaneously also reduce noise, reached quiet preferably effect.Owing to adopted the setting of stretching pulley, can make video camera start and stop stably in the middle of operation, thereby further reduce noise, reach quiet preferably effect.

Embodiment

The video camera of this embodiment as shown in Figure 1, mainly comprises core shell 7, single-arm shift bracket 1, fuselage cover 5, PCB mainboard 21, electric machine support 2, base 22, vertical pcb board 4, movement 15 and rotational structure.Wherein rotational structure comprises and horizontally rotates structure and vertical rotation structure.Single-arm shift bracket 1 and electric machine support 2 are used for firm vertical stepper motor 18.

Horizontally rotating that mechanism is connected with vertical rotation mechanism is to come connection PCB mainboard 21 and vertical pcb board 4 by conducting slip ring, realizes horizontally rotating the driven rotary of mechanism and vertical rotation mechanism.There is single-chip microcomputer to handle and horizontally rotate in the PCB mainboard 21 and drives the processing section, and in the vertical pcb board 4 the vertical drive processing section is arranged, the movement vision signal is connected with vertical pcb board 4 simultaneously, vertical pcb board 4 passes to vision signal and vertical control signal in the PCB mainboard 21, the operation that comes the processing controls complete machine by single-chip microcomputer in the PCB mainboard 21.

Horizontally rotate structure, as shown in Figure 2, comprise horizontal stepper motor 8, horizontally rotate belt 9, horizontal belt wheel 11, horizontally rotate support 12, core rack 14, horizontal bearing assembly 10 and conducting slip ring 13.Horizontal stepper motor 8 links to each other by horizontally rotating belt 9 and horizontal belt wheel 11, movement 15 fitting machine core supports 14 inside, and core rack 14 is used for balance movement 15.Wherein, the level of twining metallic steel connects lead, horizontal bearing assembly 10 and conducting slip ring 13 and forms and be connected conducting device.The accurate steel ball slip of conducting slip ring 13 inner employings reaches 360 degree full rotations, and its inside is put into the level of twining the soft alloy steel again and connected lead, and such order is for the steel ball wearing and tearing in the central level connection of operation lead can not be rotated; And conducting slip ring 13 is mounted in the inside, position, hole of bearing assembly 10, and bearing assembly 10 inside also are to adopt steel ball to make, and bearing assembly 10 plays the steadily effect of whole video camera simultaneously, and whole video camera can be offset.

This connection conducting device is used for connecting movement 15 and PCB mainboard 21.Wherein, horizontal stepper motor 8 drives the rotation of horizontal belt wheel 11, and horizontal belt wheel 11 drives and horizontally rotates belt 9 rotations.
