Abstract

The utility model discloses a panhead video camera structure, which comprises an underplate, a motor and a main board, wherein the underplate adopts a closed housing; the motor is positioned outside the underplate; a motor shaft penetrates through the underplate and is connected to the main board; a center hole corresponding to the motor shaft is formed on the underplate; and a wire of the main board penetrates through the center hole. In order to facilitate rotation of the motor, a bearing is installed in the center hole of the underplate to increase the contact between the underplate and a rotating column body and the rotation performance thereof, and the bearing is connected with a cylindrical fixing part. The patent adopts the scheme that the motor is away from the working space on the main board, thereby reducing the height of the underplate and improving the overall rotary stability of the machine; and due to great amount of heat generated due to the rotation of the motor, the operating temperature in the underplate can be greatly reduced after the motor is placed outside the underplate, the working stability of the main board is effectively guaranteed, the service life of the main board is prolonged, and the contact between the underplate and the rotating column body and the rotation performance thereof are guaranteed.

Description

A kind of pan-tilt structure

Technical field

The utility model relates to a kind of motor, mainboard and base arrangement of monopod video camera.

Background technology

Monopod video camera is a kind of of rig camera.Because of it carries two micromotors, can realize up and down and left-right rotation by computer Control Software or IE control Long-distance Control video camera self, replaced the way of traditional external The Cloud Terrace.So called after monopod video camera.

Shown in Fig. 1-2, monopod video camera is made of mainboard, CMOS/CCD plate and drive motor, and mainboard and CMOS/CCD plate all are surface-mounted integrated circuits.Machine construction in the past is placed on motor on the mainboard, is positioned at the center.Allow the electric wire that connects mainboard and CMOS/CCD plate in wire casing, pass through by around motor, excavating wire casing.Motor is placed on the mainboard, and its shortcoming is that motor position and mainboard position are too approaching, all can generate heat in the motor and the mainboard course of work, easily causes the local space temperature too high, reduces mainboard stability in use and serviceable life.Simultaneously, motor is positioned at the mainboard top and can causes the machine bottom too high, the stability when influencing the right rotation of machine integral left.And in this position, motor is difficult to fixing.By the wire casing wiring, its shortcoming is machine in the left rotation and right rotation process around motor, and electric wire can rotate thereupon.In wire casing, electric wire can arbitrarily move, and very easily causes electric wire to twine and makes the machine left rotation and right rotation not smooth.Because the winding of electric wire can cause the electric wire available range to shorten, when being rotated up and down, the machine head breaks down because of electric wire is too short.Electric wire can be pulled apart when serious, cause machine to paralyse comprehensively.

The utility model content

The purpose of this utility model provides a kind of monopod video camera structure, and the wire laying mode that solves monopod video camera commonly used is easy to generate the problem of being twined by electric wire, and the problem of heat radiation.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of pan-tilt structure comprises chassis, motor and mainboard, and the chassis is the housing of a sealing, described motor is positioned at the outside on chassis, motor shaft passes the chassis and is connected on the mainboard, and corresponding described motor shaft is provided with a center pit on the chassis, and the lead of mainboard passes from center pit; For the ease of heat radiation, around the chassis, be provided with several louvres simultaneously.

Described motor is installed in the rotating cylinder, is provided with cylindrical fixture in the bottom of rotating cylinder and the junction on chassis, and described cylindrical fixture is connected with the center pit on chassis.For the ease of the rotation of motor, in the center pit on the chassis bearing is installed, to increase the contact and the rotatory of chassis and rotating cylinder, described bearing is connected with cylindrical fixture.

The utility model has been done change with the position of motor.Originally motor is positioned at chassis and the shared work space of mainboard.Make up a rotating cylinder now, motor is placed on an independent working environment.The benefit of doing like this is:

Motor is broken away from the mainboard work space, reduced the height (being reduced to 2.8cm) on chassis, the rotational stabilization of machine integral body is improved from original 3.5cm;

Because motor rotation can produce a large amount of heat, like this with the outside of motor as for the chassis, just can greatly reduce the working temperature in the chassis, the mission life (surface-mounted integrated circuit is very poor to the tolerance of high temperature) that has effectively guaranteed the job stability of mainboard and prolonged mainboard;

Motor is in independently working environment, transmission shaft enters the chassis from top to bottom, so fixing two parts in rotating cylinder and chassis, and installed bearing between rotating cylinder and the chassis additional, guaranteed contact and rotatory between rotating cylinder and the chassis.

Under the prerequisite of moving on the motor, this patent has been cancelled original wire casing, allows the connecting line between mainboard and the CMOS/CCD plate directly pass through interstitial hole.The benefit of doing like this is: the distribution of electric wire is more simple, effectively.Stopped electric wire owing to rotating the winding that causes even pulling apart.And, in rotating cylinder, there is more space to store unnecessary electric wire, when making the head at CMOS/CCD plate place rotate up and down enough electric wire supplies are arranged, avoided the bad or electric wire of the rotation that causes because of electric wire is too short to be torn.
