Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further:
See Fig. 1 ~ 4, the holder for aerial photographing that the utility model provides, comprises housing 1, phase unit 2, rotary drive mechanism 3 and rotary positioning mechanism.Wherein, its inside of housing 1 is provided with installs chamber 103, and rotary drive mechanism 3 is located in this installation chamber 103.Housing 1 specifically can be assembled by upper shell 101 and lower house 102, forms described installation chamber 103 between upper and lower casing.Phase unit 2 is located at below housing 1, phase unit 2 specifically comprises camera mounting shell 201 and is fixedly installed in the camera 202 in camera mounting shell 201 inner chamber, what camera 202 preferably tilted is fixedly installed in camera mounting shell 201 inner chamber, and its boresight direction and vertical direction are an angle.Rotary drive mechanism 3 is connected with phase unit 2 and drives camera group 2 rotates in horizontal surface relative to housing 1.Concrete, this rotary drive mechanism 3 comprises all to be located at housing and to install driving gear 302 that the steering wheel 301 in chamber 103 is fixedly connected with steering wheel and and the driven gear 303 of driving gear engagement.And S. A. 4 is also provided with at camera mounting shell 201 top, this S. A. 4 is fixedly connected with driven gear 303, thus, when steering wheel 301 works, by the effect of driving gear 302 and driven gear 303, and finally drive camera mounting shell 201 to rotate in horizontal surface.More specifically, a through hole passed for S. A. 4 can be provided with bottom housing 1, specifically can offer this through hole on the lower house 102 of housing.S. A. 4 is fixedly connected with driven gear 303 through after this through hole again.
Make camera 202 be located shooting in order to the phase unit 2 rotated can be paused, this holder for aerial photographing is also provided with rotary positioning mechanism.Specifically, be also provided with a gland 6 in the installation chamber 103 of housing 1, this gland 6 is specifically positioned at above driven gear 303, and it may be used for installing driven gear 303 and driving gear 302.Rotary positioning mechanism specifically comprises some detents 3031 and some location hoodle 602, and wherein detent 3031 is located at driven gear 303 upper surface, and is concaved with some hoodle mounting holes 601 at gland 6 lower surface.Location hoodle 602 activity be located in hoodle mounting hole 601, location hoodle 602 can slide in hoodle mounting hole 601.Detent 3031 rotates with driven gear 303 and can turn to the position corresponding with hoodle mounting hole 601, is built in location hoodle 602 in gland 6 then for blocking the detent 3031 corresponding with hoodle mounting hole 601 position.Namely, when detent 3031 rotate to and hoodle mounting hole 601 position to correspondence time the location hoodle 602 be installed in hoodle mounting hole 601 slides into bottom mounting hole, location hoodle 602 a part of sphere from bottom hoodle mounting hole 601 to exposing outside, and be just in time stuck in detent 3031, thus the camera mounting shell 201 rotated is paused, 202, camera can locate shooting.Detent 3031 quantity of driven gear 303 upper surface can be one or more.Comparatively preferred, multiple detents 3031 that driven gear upper surface is provided with all are positioned at concentric circumferentially same with driven gear 303 center shaft; More preferred, these detents 3031 are evenly distributed in concentric circumferentially same of this and driven gear 303 center shaft, further, the quantity of detent 3031 is preferably 4, thus makes camera 202 often can carry out one-time positioning shooting by half-twist.
Further, the S. A. 4 of camera mounting shell 201 offers the axial pass-through holes 401 of passing for wire, wire is connected with camera 202 top or top via this axial pass-through holes 401, thus wire can not be tied a knot because camera rotates or be made wire degree of tightness differ because camera rotates to different angles, causes the problem of bad contact.In this axial pass-through holes, waterproof joint can be installed further.Further, camera mounting shell 201 can be assembled by upper casing 2011 and lower casing 2012.
Further, controller 7 can be provided with in the installation chamber 103 of housing 1, concrete as pcb board, this pcb board 7 and the electric connection such as steering wheel, camera.Housing 1 also can offer the telltale hole 5 for passing for the signal wire (SW) of connection control device and aircraft, this telltale hole 5 is provided with waterproof joint.
Holder for aerial photographing of the present utility model, the quantity of its phase unit 2 can have more than 1 cover or two covers.
Adopt many camera lenses holder for aerial photographing of the present utility model, its phase unit is rotatable, and can locate, and makes camera in it can flexible shooting angle, can locate shooting simultaneously, use very flexible.
The technical solution of the utility model carries out improving and obtaining on the basis of existing technology, does not carry out special version part and is the obtainable common practise of those skilled in the art or prior art, no longer repeat in the text one by one this in literary composition.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, therefore all contents not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
