DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: a six-wheel frame structure of a gimbal based on a gravity pendulum, comprising a driving bracket 12, and a supporting frame 1 is installed on both sides of the driving bracket 12. The driving bracket 12 comprises a left bracket and a right bracket, and a cross connecting frame 11 is fixedly sleeved on both the left bracket and the right bracket, and ear holes are opened on both sides of the cross connecting frame 11. The top of the supporting frame 1 is symmetrically fixedly installed with an insertion rod 20, which is inserted into the corresponding ear hole and fixedly matched with the ear hole, so as to facilitate the assembly of the overall frame.

[0024] The top of the driving bracket 12 is rotatably mounted with the pan-tilt frame 8. A rotating rod 19 is horizontally fixedly mounted between the tops of the left bracket and the right bracket, and the rotating rod 19 is rotatably mounted with the bottom of the pan-tilt frame 8. A gravity pendulum 15 is fixedly mounted at the bottom of the pan-tilt frame 8. The pan-tilt frame 8 includes a pan-tilt plate, and two symmetrically arranged swing blocks 16 are fixedly mounted at the bottom of the pan-tilt plate. The rotating rod 19 passes through the two swing blocks 16 and is rotatably mounted with the two swing blocks 16. A second connecting frame 17 is fixedly mounted between the two swing blocks 16, and the second connecting frame 17 is fixedly mounted with the gravity pendulum 15.

[0025] The bottom of the support frame 1 is symmetrically mounted with a driven wheel 2. The bottom of the support frame 1 is slidably mounted with a connecting seat 4 arranged symmetrically on the left and right, and the connecting seat 4 includes a fixed seat, and a vertically arranged first connecting shaft is fixedly mounted on the top of the fixed seat, and the first connecting shaft is slidably mounted on the bottom of the support frame 1. The first connecting shaft is in a rectangular parallelepiped shape to prevent the first connecting shaft from rotating.

[0026] The bottom of the support frame 1 is fixedly sleeved with a second stop block, and a first spring 3 is fixedly installed between the second stop block and the fixed seat of the connecting seat 4. The first spring 3 is sleeved on the bottom of the support frame 1. The bottom of the connecting seat 4 is rotatably installed with a roller frame 18, and the roller frame 18 is rotatably installed with the driven wheel 2. By installing the first spring 3, the driven wheel 2 is buffered and the vibration of the support frame 1 is reduced.

[0027] Two fixing blocks 21 are installed at the bottom of the driving bracket 12, and the two fixing blocks 21 are respectively installed by sliding cooperation with the bottom of the left bracket and the right bracket of the driving bracket 12 through the second connecting shaft. The bottom of the left bracket and the right bracket of the driving bracket 12 are respectively fixedly sleeved with a first stop block, and a second spring 22 is fixedly installed between the first stop block and the fixing block 21. By installing the second spring 22, a buffering effect is played on the fixing block 21, thereby reducing the vibration of the driving bracket 12.

[0028] The fixed block 21 is in an inverted "U" shape, and a driving wheel 13 is rotatably mounted in the fixed block 21. A driving motor 14 is fixedly mounted on one side of the fixed block 21, and the driving motor 14 is fixedly mounted with the driving shaft of the driving wheel 13, providing the power for the whole device to move.

[0029] A buffer assembly is installed between the pan-tilt frame 8 and the supporting frame 1. The buffer assembly includes two fixed-length push rods 7 and two damping push rods 10. A first hinge block 6 is symmetrically slidably installed on the top of the supporting frame 1, and second hinge blocks 9 are symmetrically fixedly installed on the front and rear sides of the bottom of the pan-tilt plate of the pan-tilt frame 8. One end of the two fixed-length push rods 7 is respectively hinged to the first hinge block 6 corresponding to the front side of the pan-tilt plate, and the other end of the two fixed-length push rods 7 is respectively hinged to the second hinge block 9 corresponding to the rear side of the pan-tilt plate. One end of the two damping push rods 10 is respectively hinged to the first hinge block 6 corresponding to the rear side of the pan-tilt plate, and the other end of the two damping push rods 10 is respectively hinged to the second hinge block 9 corresponding to the rear side of the pan-tilt plate.

[0030] When the slope changes, the gravity pendulum 15 drives the pan-tilt frame 8 to remain horizontal due to the action of gravity via the second connecting frame 17, and maintains the stability of the pan-tilt frame 8 through the combined movement of the T-shaped slide rail 5, the damping push rod 10 and the fixed-length push rod 7.

[0031] A T-shaped slide rail 5 is symmetrically fixedly installed on the top of the support frame 1, and the T-shaped slide rail 5 is slidably mounted with the corresponding first hinge block 6. The T-shaped slide rail 5 has the function of limiting and guiding the first hinge block 6.

[0032] The working principle of the six-wheel frame structure of the gimbal based on the gravity pendulum provided by the utility model is as follows:

[0033] During mobile shooting, the driving motor 14 is started, and the driving motor 14 drives the driving wheel 13 to rotate, so that the driving wheel 13 drives the entire device to move.

[0034] When the slope changes, the vehicle body tilts along with the slope, and the gravity pendulum 15 swings due to the action of gravity, that is, the gravity pendulum 15 is always perpendicular to the horizontal ground and vertically downward, so that the gravity pendulum 15 drives the pan-tilt frame 8 to remain horizontal, and maintains the stability of the pan-tilt frame 8 through the combined movement of the T-shaped slide rail 5, the damping push rod 10, and the fixed-length push rod 7.

[0035] When the terrain slope changes continuously, the gravity pendulum 15 will oscillate repeatedly, thus affecting the stability of the gimbal frame 8. At this time, by fixing the front T-shaped slide rail 5 connected to the fixed-length push rod 7, the rear T-shaped slide rail 5 connected to the damping push rod 10 can perform contour movement. When the terrain slope changes continuously, the damping effect of the damping push rod 10 can buffer the oscillation of the gravity pendulum 15 to ensure the stability of the gravity gimbal frame 8.

[0036] At the same time, when the driven wheel 2 and the driving wheel 13 pass through the terrain with continuously changing slope, the driven wheel 2 and the driving wheel 13 will buffer the driven wheel 2 and the driving wheel 13 through the cooperation of the provided connecting seat 4 and the first spring 3, and the fixing block 21 and the second spring 22, thereby improving the shock absorbing performance of the driven wheel 2 and the driving wheel 13 and making the pan-tilt stand 8 more stable.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
