Abstract
The present invention relates to a kind of two-degree-of-freedom cradle head, comprise support and the motor and speed reducer structure that is installed on the support, its special character is that this The Cloud Terrace is provided with two tilting mechanisms, and each tilting mechanism is realized swinging back and forth in the plane, and two swings can independently separately realize.Tilting mechanism mainly is made up of a wobble gear, a transition gear, a partial gear and a sector gear.This The Cloud Terrace can be realized the oscillating motion of The Cloud Terrace when the drive motor single direction rotates, and accurate positioning, and the oscillating motion scope of The Cloud Terrace can recently be adjusted by the transmission that changes tilting mechanism; The speed of The Cloud Terrace swing can be realized by the speed of regulating drive motor as requested.And this The Cloud Terrace processing is simple, and cost is low, also can apply to the occasion that other need be swung, and has use value widely.
Description
Technical field
The present invention relates to a kind of two-degree-of-freedom cradle head, belong to controlled payload platform, it can drive it and load in two orthogonal planes and to rotate, this rotation can be independent also can be simultaneously.
Background technology
Along with the continuous progress of society, the range of application of frequency image monitoring system is more and more wideer, is widely used in occasions such as bank, traffic, market, intelligent residential district.For the multi-angle that realizes Long-distance Control is taken, video capture devices such as common video camera are installed on the two-degree-of-freedom cradle head, what existing two-degree-of-freedom cradle head adopted mostly is by controlling the positive and negative swing that transfers the realization video camera of motor, this class The Cloud Terrace requires than higher control section, and the swing speed that is difficult to the realization video camera is usually stablized constant, therefore, adopt simple mechanism and control circuit to realize that the constant speed swing of video camera is a problem anxious to be solved at present.
Summary of the invention
For solving problems of the prior art, the invention provides a kind of two-degree-of-freedom cradle head that video capture devices such as video camera are installed, this The Cloud Terrace can make the swing of video camera constant speed, realize the multi-angle shooting of Long-distance Control, to be used for tracking, shooting, acoustic image, monitoring, robot computer video, teleconference etc., also can apply to the occasion that other need make hunting of load.
Technical scheme provided by the invention is: a kind of two-degree-of-freedom cradle head, mainly comprise support and the motor and speed reducer structure that is installed on the support, it is characterized in that: the motor via reducer structure drives tilting mechanism, tilting mechanism comprises a wobble gear, a transition gear, a partial gear and a sector gear, wobble gear and transition gear engagement, partial gear and sector gear are coaxial, motor drives partial gear and sector gear rotation through reducing gear, and wobble gear is driven by sector gear and transition gear in turn; And in two orthogonal planes, be respectively equipped with tilting mechanism, drive by independent motor and speed reducer structure respectively; And when partial gear and wobble gear stop engagement, sector gear and transition gear engagement, and partial gear and wobble gear be when meshing, sector gear is in transition gear and separates shape.
Wherein said reducing gear is a worm-and-wheel gear.
By technique scheme as can be known this The Cloud Terrace be to utilize gear drive to realize the oscillating motion of The Cloud Terrace, so its accurate positioning, the oscillating motion scope of The Cloud Terrace can recently be adjusted by the transmission that changes tilting mechanism; The speed of The Cloud Terrace swing can be realized by the speed of regulating drive motor as requested, and this The Cloud Terrace can be realized the oscillating motion of The Cloud Terrace by adopting transition gear when the drive motor single direction rotates.In addition, this The Cloud Terrace processing is simple, and cost is low, also can apply to the occasion that other need be swung, and has use value widely.

Embodiment
The present invention relates to a kind of The Cloud Terrace of two-freedom.With reference to Fig. 1, Fig. 2, this The Cloud Terrace mainly comprise support 1, back up pad 2. worm screw 3. worm gear 4, axle I5, axle II6, end cap 7, swinging mounting 8, axle III9, wobble gear 11, transition gear 12, partial gear 13, sector gear 14 and as the motor of power source.Camera 10 is driven by wobble gear 11.. worm screw 3 and worm gear 4 constitute reducing gear, tilting mechanism mainly is made up of wobble gear 11, transition gear 12, partial gear 13 and sector gear 14, wobble gear 11 and transition gear 12 engagements, partial gear 13 and sector gear 14 are coaxial, motor drives partial gear 13 and sector gear 14 rotations through worm and gear, wobble gear 11 is driven by sector gear 14 and partial gear 13 in turn, to realize that camera 10 swings up and down.When wobble gear 11 was driven by partial gear 13, wobble gear 11 drove upwards swing of camera 10; When sector gear 14 meshed with transition gear 12, wobble gear 11 was driven by transition gear 12, and wobble gear 11 drives cameras 10 to lower swing.In order to keep the continuity of wobble gear 11 swings, must be when partial gear 13 and wobble gear 11 stop engagement, sector gear 14 and transition gear 12 engagements, and partial gear 13 is during with wobble gear 11 engagements, sector gear 14 is in released state with 12 of transition gears.
Present embodiment is respectively equipped with tilting mechanism in two orthogonal planes, driven by independent motor and speed reducer structure respectively.The action principle of two parts is identical, the motor of other direction by behind the worm and gear speed-reduction apparatus with same reciprocally swinging principle, swinging mounting 8 is swung, and then drives camera 10 and swing.
Claims (2)
1. the The Cloud Terrace of a two-freedom, mainly comprise support and the motor and speed reducer structure that is installed on the support, it is characterized in that: the motor via reducer structure drives tilting mechanism, tilting mechanism comprises a wobble gear, a transition gear, a partial gear and a sector gear, wobble gear and transition gear engagement, partial gear and sector gear are coaxial, motor drives partial gear and sector gear rotation through reducing gear, and wobble gear is driven by sector gear and partial gear in turn; And in two orthogonal planes, be respectively equipped with tilting mechanism, drive by independent motor and speed reducer structure respectively; And when partial gear and wobble gear stop engagement, sector gear and transition gear engagement, and partial gear and wobble gear be when meshing, sector gear is in transition gear and separates shape.
