DETAILED DESCRIPTION

[0026] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Embodiment 1: like Figure 1 As shown, a three-dimensional centralized integrated mechanical auxiliary shooting gimbal is used as the main body of the present invention. The upper part is hinged with the surrounding bracket part 2, the lower part is movably connected with the groove wheel mechanism 4, and the bottom end is mortise and tenoned with the counterweight plate 5. The surrounding bracket part 2 is hinged with the shooting equipment clamping device 1.

[0029] The shooting equipment clamping device 1, as a special device for fixing the shooting equipment, cooperates with the surrounding bracket part 2 to accurately adjust and determine the required shooting points and shooting angles to meet the multi-degree-of-freedom and multi-directional shooting needs. The spoke-wheel rotating platform 3, as the support platform of the photographed object and the main body of the device, is provided with multiple interfaces to completely connect the various parts in series, and can realize the rotation of the object around the central axis of the wheel turntable 3-3. The surrounding bracket part 2 is tightly combined with the spoke-wheel rotating platform 3 to form an integrated surround design, which is not only easy to carry and operate, but also does not require cumbersome adjustments before shooting. As a classic intermittent mechanical transmission structure, the groove wheel mechanism 4 can realize the precise stop of the wheel turntable 3-3 by 30° every time it rotates 360° under the drive of the operating joystick 3-8. The corresponding interface of the counterweight plate 5 can be flexibly mortised between any two legs of the gimbal main frame 3-1. The position of the counterweight plate 5 can be adjusted according to the balance state of the device. By placing a heavy object in the central position of the counterweight plate 5, the torque generated when clamping the shooting equipment can be effectively balanced to ensure the stability and reliability of the shooting process.

[0030] Further, such as Figure 2 As shown, the spoke-wheel rotating platform 3 includes a pan-tilt main frame 3-1, an inter-axial connecting rod 3-2, and a wheel-type turntable 3-3. Two connecting ears 3-1-1 are symmetrically arranged on the top of the pan-tilt main frame 3-1, and the wheel-type turntable 3-3 is movably connected to the center. The inter-axial connecting rod 3-2 is mortised at the bottom, and four supporting columns are evenly distributed around. A large and a small through hole are respectively provided on the inter-axial connecting rod 3-2, and the center line of the two through holes is perpendicular to the center line of the through holes on the two connecting ears 3-1-1. The spoke-wheel rotating platform 3 is hinged to the surrounding bracket part 2 through the connecting ear 3-1-1, and is movably connected to the groove wheel mechanism 4 through the inter-axial connecting rod 3-2. This design can achieve the effect of 360° free rotation of the wheel turntable around its own rotating axis. The pan-tilt main frame 3-1 not only reserves multiple interfaces to enable the various parts to be fully connected in series, but also arranges the interface positions in a regular manner, which can effectively avoid motion interference during operation.

[0031] Further, such as Figure 4 As shown, the grooved wheel mechanism 4 includes a grooved wheel 4-1, a driving wheel shaft shoulder 4-2, a driving wheel shaft 4-3, and a driving wheel 4-4 operating rocker 4-5. The upper end of the driving wheel shaft 4-3 passes through a small hole on one side of the inter-axial connecting rod 3-2, and is mortised with the driving wheel shaft shoulder 4-2 by setting a center hole at the upper end to fix the position of the rotating shaft, and is mortised with the driving wheel 4-4 by setting two holes at the lower end to achieve the effect of common rotation. The driving wheel 4-4 is mortised with the operating rocker 4-5 by setting a center hole at its lower end, and remains coaxial with the driving wheel shaft 4-3 and the driving wheel shaft shoulder 4-2 to ensure the stability and accuracy of the transmission.

[0032] Furthermore, the driving wheel 4-4 is provided with a cylindrical pin 4-4-1 and a semicircular locking arc 4-4-2, the groove wheel 4-1 is located between the driving wheel shaft 4-3 and the driving wheel 4-4, and its central hole is tightly connected with the tail of the rotating shaft of the wheel-type turntable 3-3 to rotate together, and the wheel circumference is evenly distributed with the same number of guide grooves 4-1-1 and concave arc surfaces 4-1-2, and the cylindrical pin 4-4-1 and the semicircular locking arc 4-4-2 on the driving wheel 4-4 respectively coordinate with the guide groove 4-1-1 and concave arc surface 4-1-2 on the groove wheel 4-1. By operating the operating rocker 3-8 located below the groove wheel mechanism, the wheel-type turntable 3-3 can be driven to rotate around its central axis at a predetermined angle, and a precise stop is achieved after each 30° rotation.

[0033] Further, such as Figure 3 As shown, the surrounding bracket part 2 includes a guide rail connecting block 2-1, an arc guide rail 2-2, a straight guide rail 2-3, a bent rod 2-4, and a straight guide rail slider 2-6. The two guide rail connecting blocks 2-1 are respectively hinged to the outer sides of the two connecting ears 3-1-1, and are connected to the two ends of the arc guide rail 2-2 by arranging square bosses on the surface. The center of the arc guide rail 2-2 is located on the central symmetry plane of the straight guide rail 2-3, and is movably connected to the front through-notch of the straight guide rail 2-3 through a movable pair. Groove structures are symmetrically provided on both sides of the straight guide rail 2-3. The groove structure is movably connected to the lower part of the straight guide rail slider 2-6 located above it through a movable pair. The circular notch above the straight guide rail slider 2-6 is movably connected to the cylindrical boss below the upper bent rod 2-4 through a rotating pair. The front end of the bent rod 2-4 is hinged to the shooting equipment clamping device 1. The combination of the multi-slider and the rotating pair provides a high degree of freedom of movement, and through manual operation, full point coverage within the hemispherical surface centered on the object being photographed above the turntable is achieved.

[0034] Further, such as Figure 5 As shown, the photographing equipment clamping device 1 comprises a static clamping arm 1-1, a clamping device rear cover 1-2, and a dynamic clamping arm 1-4. The clamping device rear cover 1-2 and the dynamic clamping arm 1-4 are provided with a pair of cylindrical bosses, and two tension springs are provided between the two pairs of cylindrical bosses to achieve elastic connection. The back of the clamping device rear cover 1-2 is hinged to the bent rod 2-4, and the front is mortise-jointed to the static clamping arm 1-1. This device can ensure stability during holding and is compatible with a variety of photographing equipment.

[0035] Furthermore, the counterweight plate 5 can be tightly connected to the bottom ends of any two support columns below the main frame 3-1 of the gimbal by setting two symmetrical interfaces. The position of the gimbal can be adjusted according to its balance state, and heavy objects can be placed on it to prevent the gimbal from tipping over due to a large torque caused by clamping too heavy equipment.

[0036] Furthermore, at the hinged connection between the camera clamping device 1 and the surrounding bracket part 2 and at the hinged connection between the spoke wheel type rotating platform 3 and the surrounding bracket part 2, the bolt tail ends are respectively screwed with manually operable locking nuts I1-3 and locking nuts II2-9, and the two have the same axial direction. The camera clamping device and the arc guide rail 2-2 can be adjusted and locked by operating the two locking nuts.

[0037] Furthermore, the front end face of the straight guide rail 2-3, the right end face of the straight guide rail slider 2-6 and the right side of the circular notch above them are all provided with through holes, in which set screws I2-8, II2-5 and III2-7 are respectively screwed, wherein the axial directions of set screws II2-5 and III2-7 are the same, and the axial directions of set screws I2-8 and II2-5 are perpendicular. By operating the three set screws, the overall state of the surrounding bracket part 2 can be adjusted and locked.
