Description

Shaft arm rotating connection driving device

Technical Field

The utility model belongs to the technical field of holder equipment, and particularly relates to a driving device for rotary connection of a shaft arm.

Background

At present, the handheld cloud platform of diaxon is prepared and is favored by the user, and its leading cause includes that the handheld cloud platform volume of relative triaxial is less, and the person of facilitating the use carries. The conventional common accommodating volume reducing means of the three-axis tripod head comprises the steps of reducing the volume of the tripod head by lightening and thinning a motor; or the rotor end of the pitching shaft motor is arranged in the clamping part to reduce the thickness of the motor, so that the volume of the tripod head after being accommodated is reduced; however, the structure that adopts frivolous motor structure, motor to install in the inside of clamping part can't directly be used in the diaxon cloud platform, and current diaxon cloud platform only has a vertical linking arm, if adopt above-mentioned structure, then the whole focus of cloud platform will incline to the direction of linking arm, leads to cloud platform motor load too big, and long-time use can lead to the cloud platform motor to overheat, brings irreversible damage for the motor. In addition, the existing two-axis cradle head has some disadvantages in the using process, and firstly, in the aspect of the storage of the cradle head, no product or technology which meets the storage requirements of a user exists; secondly, in the application aspect of wide-angle shooting equipment, the existing holder motor can enter a shooting range to influence the shooting effect; thirdly, in the aspect of the gravity center of the two-axis tripod head, the existing tripod head needs to make the cross rolling motor or the clamping part thick to meet the balance of the tripod head, and the method can increase the storage volume of the tripod head and is against the original intention of a user for adopting the two-axis tripod head; fourthly, in the aspect of adjusting the pitching direction of the two-axis tripod head, a course axis motor and a roll axis motor are mostly adopted by the two-axis tripod head, so that the pitching direction cannot be adjusted; fifthly, in the aspect of the clamping part of the holder, the existing clamp is wide, and the occupied space is large during storage.

Therefore, the two-shaft tripod head with the bulletin number of 'CN 113137554A', wherein the connecting arm and the rotor end of the first motor can rotate relatively to drive the tripod head to switch between the storage state and the use state; the clamping part comprises a first clamping jaw and a second clamping jaw, and when the holder is in a storage state, the clamping part faces the handheld part; when the holder is in a use state, the clamping part is positioned above the first motor, and the connecting arm inclines towards the axis extension line of the first motor, so that the clamping part is positioned on the axis extension line of the first motor. The two-shaft tripod head disclosed by the utility model can meet the condition that the gravity center of the two-shaft tripod head is always balanced, and the rotating mechanism is additionally arranged between the first motor and the connecting arm to meet the requirement of accommodating the two-shaft tripod head, so that the length of the two-shaft tripod head is only the length of a handheld part of the tripod head after the two-shaft tripod head is accommodated, and meanwhile, the problem of shielding of the motor when the two-shaft tripod head is shot by using a wide-angle lens can be solved.

For the two-shaft tripod head, although a second motor which is light and thin or part of components of the second motor are arranged in the two-shaft tripod head inside the clamping part, the inclined connecting arm is adopted, so that the gravity center of the two-shaft tripod head can be always balanced; by adopting the structure of the utility model, the contained holder is only provided with the handheld part; adopt simple rotating-structure, realized the regulation of diaxon cloud platform in the pitch direction, but it still has following comparatively obvious defect in the use: although the above-mentioned device adopts the linking arm of slope, can satisfy diaxon cloud platform focus balance all the time, but do not possess the height of slope to the linking arm and carry out sliding adjustment, thereby make the linking arm utilize upwards lifting of arm to adjust its height, can make staff's arm appear shake and horizontal hunting like this, and then can lead to the picture quality that the cloud platform was shot relatively poor, it is only that the pivot of solitary utilization motor carries out drive pivoted mode comparatively simple that above-mentioned linking arm drive is connected in the rotation simultaneously, and can produce great shake and unstable problem when adjusting the rotation to the linking arm at the shooting in-process, and this kind of linking arm can make the overall stability of cloud platform reduce with the mode of the rotation connection drive of motor, thereby can't realize high-quality shooting.
