Detailed Description
The present invention will be further described with reference to the drawings and examples.
As shown in fig. 1 and 2, a dome camera transmission device, the dome camera comprises an upper cover 15 and a transmission device 14 which are arranged on a wall-mounted bracket 16; the transmission device 14 comprises a base 1, and a conical fluted disc 13 is arranged on the lower surface of the base 1; the base 1 is connected with a main support through a bearing, a first rotary support 6 and a second rotary support 7 are respectively arranged on two sides of the main support, U-shaped baffles are arranged on the edges of the two rotary supports, and the openings of the U-shaped baffles are upward; a sphere rear shell 9 is arranged between the two rotary brackets, and the sphere rear shell 9 is connected with the two rotary brackets through a bearing; the left and right sides of the inner wall of the sphere rear shell 9 are respectively provided with a horizontal rotation driving motor 4 and a pitching rotation driving motor 8, a rotor of the horizontal rotation driving motor 4 is fixed with a first synchronous belt pulley 5, and a rotor of the pitching rotation driving motor 8 is fixed with a second synchronous belt pulley 10; the first synchronous belt wheel 5 is connected with the bevel gear belt wheel assembly 2 through the first synchronous belt 3, and a bevel gear meshed with the bevel gear disk 13 and a fourth synchronous belt wheel are attached to the bevel gear belt wheel assembly 2; the second synchronous pulley 10 is connected with a third synchronous pulley 12 through a second synchronous belt 11, and the third synchronous pulley 12 is connected with the sphere rear shell 9 through a connecting rod in a static manner; a round hole for the connecting rod to pass through and an arc hole 17 for the rotor of the pitching rotation driving motor 8 to pass through are formed on the second rotation bracket 7; the circle center of the circle where the arc-shaped hole 17 is located coincides with the circle center of the circle where the third synchronous pulley 12 is located.
The first synchronous belt 3 is connected with a first synchronous pulley 5 and a fourth synchronous pulley.
The first synchronous belt 3 and the second synchronous belt 11 are rubber belts with teeth formed on the inner sides.
The base 1, the first rotary support 6 and the second rotary support 7 are all made of plastic materials, and the rear spherical shell 9 is made of aluminum alloy materials or plastic materials.
The gear ratio of the second synchronous pulley 10 to the third synchronous pulley 12 is 1:4; the gear ratio of the first synchronous pulley 5 and the fourth synchronous pulley is 1:1.2.
The horizontal rotation driving motor 4 and the pitching rotation driving motor 8 are stepping motors.
The application method of the invention comprises the following steps:
the whole spherical camera transmission device 14 is fixed with the upper cover 15 through the base 1, meanwhile, the upper cover 15 is fixed on a wall-mounted bracket 16 or a hoisting bracket, and finally, the wall-mounted bracket 16 or the hoisting bracket is fixed on a wall; the movement (imaging mechanism) of the spherical camera is mounted in the sphere rear case 9.
When the pitching rotation driving motor 8 is operated, since the second timing belt 11 is driven, when the timing pulley 10 is self-driven, the effect of the final driving motion is that the second timing pulley 10 revolves around the third timing pulley 12. I.e. the pitching rotation driving motor 8 makes a circular movement with a maximum amplitude of 1/4 around the centre of the third synchronous pulley 12 in the direction of the arc-shaped hole 17. And then the whole sphere rear shell 9 rotates to realize pitching rotation movement of the sphere relative to the rotary support. In the process from the minimum pitch angle rotation to the maximum pitch angle rotation, the rotor of the pitch rotation driving motor 8 moves in the arc-shaped hole 17 and moves from one end to the other end of the arc-shaped hole 17.
When the horizontal rotary motor 4 works, the horizontal rotary motion of the sphere and the rotary support relative to the base 1 is realized through the transmission of the first synchronous belt 3 and the reversing of the meshing of the bevel gears. Because the base is fixed relative to the wall, the horizontal rotation of the sphere is finally realized.
When the motions are combined, the shooting scene of the camera movement can be changed in a three-dimensional space, so that the basic function of the spherical camera is realized.
