Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 is a kind of schematic diagram of the stable head of self-propelled virtual reality camera shooting, and wherein VR cameras 1 can be multiple
The combining form of camera can also be monomer VR cameras, can also install common camera, and video camera.If allow system
Performance is more preferable, is installing general camera and during video camera, it is necessary to a switching support, and adjusts switching support as far as possible,
The center of gravity of camera or video camera is set to fall in the center of head assembly 2, to reduce the control moment needed for motor.
Connected between head assembly 2 and control cabinet 4 by pole 3, pole 3 be it is hollow, for cable wire 206 and system control
Cable processed passes through.Wherein the length of pole 3 can arbitrarily determine according to the height requirement of shooting.
Fig. 2 and Fig. 3 is head assembly structure chart, and the head assembly 2 can be used alone, can also be with other filming apparatus
It is used in combination, is easily fixed on other filming apparatus, be controlled by screw 207, see Fig. 4.The top of head assembly 2
Camera mounting disc 201 be arranged on the rotor 2021 of course motor 202, stud 2011 above is used to install various cameras,
Including VR cameras 1.And the deflection of camera can be adjusted by course motor 202.Due to there is no any company on rotor 2021
Wire is connect, therefore can arbitrarily be rotated.Camera attitude detecting sensor may be mounted at the bottom of motor installing hole 2031, also may be used
With between camera mounting disc 201 and rotor 2021.
Motor cabinet 203, cross axle 204, head seat 205 are combined together, and can be swung to any direction, be passed through three bar steels
Rope 206 coordination control, can compensate because in the walking process of chassis 5 because road injustice caused by VR cameras 1 swing influence.
The stator 2022 of course motor 202 is arranged in the motor installing hole 2031 of the ring flange of motor cabinet 203.Motor cabinet
203 top cable wire hole 2032 is countersunk, and the plush copper 2061 of three cable wires 206 is embedded in the top cable wire hole of motor cabinet 203
Fixed in 2032, and the swaying direction and amplitude of controlled motor seat 203.
The uniform 3 bottoms cable wire hole 2052 around it of head seat 205, bottom cable wire hole 2052 is through hole, can make steel
Rope 206 can pass through pole 3 to reach control cabinet 4.
Fig. 5 is control cabinet schematic diagram, and the pole pedestal 401 on control cabinet 4 is used to install pole 3, and centre has perforate to lead to
Cross cable wire 206 and various cable conductors etc..Antenna 403 is arranged on control cabinet 4, can receive Bluetooth of mobile phone signal, WIFI letters
Number or other wireless controllers signal, for remotely to stablizing the straighforward operation of head and chassis.
Three motors 407 are arranged on electric machine support 405, and positioned at the underface of pole pedestal 401.Motor
407 output shaft is connected with rocker arm assembly 408.The end of cable wire 206 passed through from pole 3 is fixed on rocker arm assembly 408
And be tensioned, the rotational angle can of control motor 407 controls head group by rocker arm assembly 408 with running wire 206
The angles and positions of part 2.
Battery 404 is installed inside control cabinet 4, electric energy can be provided for whole system, see Fig. 7.The posture inspection of system
Survey, head motor 407 is controlled, and chassis movable motor 504 is controlled and completed by control panel 406.Control panel 406 is also logical
The signal and host computer for crossing reception antenna 403 are communicated.
Control cabinet 4 is arranged on chassis 5 by damper wire 503, sees Fig. 6.Wherein damper wire 503 needs to install
4 or multiple.The damping Impact direction of damper wire 503 is anisotropic, therefore the installation of damper wire 503 needs
Orthogonal direction is wanted, 90 ° of installations of mutual deviation, ensures that damping effect all directions are identical, sees Fig. 9.Subtracting for other forms can also be installed
Shake device or using the vehicle chassis with damping, make damping effect more preferable.The main function of damper is to reduce height
Influence of the frequency vibration to photographic equipment, low-frequency vibration are compensated by head.
Fig. 9 is the schematic diagram of chassis 5, and wherein chassis 5 includes sole 501, Mecanum wheel 502, damper wire 503,
Movable motor 504.Control is coordinated to four movable motors 504 using control panel 406, drives Mecanum wheel 502, then by right
The different rotating speeds of four Mecanum wheels 502 and the control turned to, chassis 5 can be made to advance, retreat, left and right translates, random angle
Spend the operation such as direction translation, pivot stud.So that a kind of stable head of self-propelled virtual reality camera shooting is than narrow
In space can any direction move freely, coordinate pushing away, drawing, shaking, moving etc. needed for shooting to shoot skill and technique so that shooting effect is more
It is good.
Figure 11 and Figure 12 is the schematic diagram of rocker arm assembly 408, including Rocker arm 4 081, fixed screw 4083, stretcher 4088, lock
Tight screw rod 40810, locking nut 4087.Wherein there are axis hole 4082, stretcher hole 4084, the axle of motor 407 on Rocker arm 4 081
Insertion axis hole 4082 is simultaneously fixed by fixed screw 4083.By controlling motor 407 to rotate, Rocker arm 4 081 is further controlled
Swing, so as to control the rotation of head assembly 2 by cable wire 206.Three cooperations of motor 407, can control head
Component 2 is swung to any direction, so as to compensate because of vibration of the walking mechanism in uneven ground running therefore.
There are a cable wire hole 4085 and screwed hole 4089 on stretcher 4088, screw rod 4086 is arranged in stretcher hole 4084
And the height of Rocker arm 4 081 can be stretched out by rotating adjusting screw rod 4086.
There is a locking hole 40811 on tie down screw 40810, when tie down screw 40810 is threaded into hole 4089, make cable wire
Hole 4085 and locking hole 40811 are alignd, and cable wire 206 is sequentially inserted into cable wire hole 4085 and locking hole 40811, then locking screw again
The other end of bar 40810 is tightened by locking nut 4087, and such can of locking hole 40811 pins cable wire 206, then rotates
Stretcher 4088 is tensioned cable wire 206.Righting head assembly 2 first is needed during tensioning, then coordinates to be tensioned three cable wires again
206。
In addition cable wire can be screwed using other structures form come fixing tightwire 206, such as two intermediate plates
206, then it is tensioned by adjusting the rotation cable wire 206 of Rocker arm 4 081 of motor 407.
Figure 13 is position sensor assembly schematic diagram, is first fixed on position sensor assembly 409 by support 4097
On electric machine support 405, then by cable wire 206 through the cable wire hole 4092 on chuck 4091, when cable wire 206 is in rocker arm assembly 408
It is fixed and is tensioned and then chuck 4091 is connected with sliding bar 4095 using screw a4094, so works as motor
407 rotation Rocker arm 4s 081 drive sliding bar 4095 to move identical distance when cable wire 206 is moved up and down, therefore sense
The can of device 4096 measures the distance of the movement of cable wire 206, so as to calculate the angle of the swing of head assembly 2.
Code-disc, rotary transformer, swept resistance, magnetic coder etc. can also be utilized to be arranged on the rotating shaft of motor 407
On, by detecting the angle of the rotation of motor 407, recycle the length computation of Rocker arm 4 081 to go out the distance of the movement of cable wire 206,
So as to calculate the angle of the swing of head assembly 2.
Figure 14 is this project medium cloud platform stability contorting schematic diagram, using the control of three cable wires 206, can to work as pole
3 keep VR cameras 1 to keep perpendicular attitude constant when tilting, and VR cameras 1 is kept stable all the time in motion process, improve and clap
Take the photograph quality.
