Description

Technical Field

[0001] The utility model belongs to the field of unmanned aerial vehicle gimbals, and more specifically, particularly relates to a dual-axis steering gear gimbal. Background Art

[0002] UAV gimbal refers to the support equipment used by UAVs to install and fix mission loads such as cameras. The camera is controlled to rotate in space through a dual-axis servo so that the UAV can carry the camera for high-altitude remote shooting from multiple angles. At present, the UAV gimbal only uses a servo in conjunction with a multi-angle adjustable support frame to complete the camera's shooting action. When the UAV falls back to the ground, the UAV will generate a large vibration when it touches the ground. The traditional UAV gimbal is usually a rigid fixed connection structure at the bottom of the UAV. The gimbal itself does not have a buffering and shock-absorbing mechanism. The vibration of the UAV touching the ground will be directly transmitted to the internal reduction gear of the servo and the precision optical devices inside the UAV camera equipment through the support frame, causing vibration damage to the camera equipment and the servo, reducing the service life of the camera and the servo gimbal. In addition, cameras of different sizes will use mounting frames of different structural sizes and be assembled with fixing screws. It can be seen that the traditional UAV gimbal cannot effectively adapt to the installation of cameras of different sizes, and the fixing screw installation method is complicated to operate, and the screw parts are easy to lose after disassembly.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1-Figure 6 As shown, the utility model provides a dual-axis servo gimbal, including a guide support rod 3; the top end of the guide support rod 3 is welded to the lower side of the fixing frame 1; it also includes an X-axis rotating servo 4, a rubber sleeve 6, an unmanned aerial vehicle motion camera 8, a clamping plate 9, a gimbal bracket 10, a knob 11, a baffle plate 14, a spring 15, a transmission rod 16, an active bevel gear 19 and a rotating shaft 20; the upper side of the baffle plate 14 is welded to the lower side of the guide column 13; the bottom end of the spring 15 is welded to the upper side of the baffle plate 14, and the top of the spring 15 is welded to the shock absorber frame 2; the X-axis rotating servo 4 is connected to the left side of the gimbal bracket 10 through a bolt; the upper side of the gimbal bracket 10 is provided with a through hole, and the fixing column 18 is rotatably connected to the through hole of the gimbal bracket 10; the transmission rod 16 is fixedly connected to the Y-axis rotating On the servo output shaft of the rotating servo 5; the Y-axis rotating servo 5 is connected to the right side of the pan-tilt bracket 10 by bolts; the rotating shaft 20 is fixedly connected to the servo output shaft of the X-axis rotating servo 4 by a key, and the rotating shaft 20 is welded to the flip support plate 7; the active bevel gear 19 is welded to the outer side of the transmission rod 16, and the active bevel gear 19 is meshed with the driven bevel gear 17; the driven bevel gear 17 is welded to the bottom end of the fixed column 18; the top of the fixed column 18 is welded to the lower side of the shock-absorbing frame 2; the top of the guide column 13 is welded to the lower side of the fixed frame 1; the knob 11 is welded to the left end of the threaded rod 12; the threaded rod 12 is meshed with the clamping plate 9 by threads; a through hole is provided in the center of the upper side of the shock-absorbing frame 2, and the rubber sleeve 6 is bonded in the through hole of the shock-absorbing frame 2.

[0022] When the utility model is installing the drone camera, first place the drone motion camera 8 between the clamping plates 9, and then manually twist the knob 11, the knob 11 drives the threaded rod 12 to rotate in the small through hole of the convex plate of the flip support plate 7, because the positive thread end and the reverse thread end of the outer side of the threaded rod 12 are respectively meshed with each other at the threaded through holes of the two groups of clamping plates 9, the threaded rod 12 can drive the two groups of clamping plates 9 to move synchronously to the left and right, until the rubber gaskets of the two groups of clamping plates 9 are respectively tightly fitted on the left and right sides of the drone motion camera 8, so that the two groups of clamping plates 9 can fix and clamp the drone motion camera 8. When the drone motion camera 8 is turned to shoot, the servo output shaft of the Y-axis rotating servo 5 drives the transmission rod 16 to rotate, and the transmission rod 16 drives the active bevel gear 19 welded on the outer side to rotate. Since the driven bevel gear 17 is meshed with the active bevel gear 19, the active bevel gear 1 9 rotates around the longitudinal center axis of the driven bevel gear 17, so that the pan / tilt bracket 10 drives the UAV motion camera 8 clamped by the clamping plate 9 to perform a 360-degree rotation movement around the vertical Y axis for shooting, and the steering gear output shaft of the X-axis rotating steering gear 4 drives the rotating shaft 20 to rotate, so that the rotating shaft 20 drives the welded flip support plate 7 to rotate, and at this time, the UAV motion camera 8 clamped by the meshing structure of the clamping plate 9 and the threaded rod 12 on the flip support plate 7 performs a flip movement around the X axis, completing the XY dual-axis steering shooting of the UAV motion camera 8. When the UAV touches the bottom and lands, the guide column 13 welded at the bottom end of the fixing frame 1 will vibrate vertically with the UAV, and the elastic stretching characteristics of the spring 15 and the rough surface of the rubber sleeve 6 form a friction damping effect on the outer side of the guide column 13, slowing down the vertical vibration transmission between the guide column 13 and the shock absorbing frame 2, and preventing the internal optical components and steering gear parts of the UAV motion camera 8 from being damaged by vibration.

[0023] In the embodiment of the present disclosure, there are two groups of splints 9, which are symmetrically distributed on the left and right. Each group of splints 9 is provided with threaded through holes and through holes that pass through the left and right sides. The threaded rod 12 is connected to the threaded through holes of the splint 9 through the threaded engagement of the outer side surface. The rotating shaft 20 is inserted into the through holes of the splint 9. The threaded rod 12 can drive the splint 9 to translate left and right. Rubber gaskets are bonded to the splints 9. The drone motion camera 8 is placed between the two groups of splints 9. The rubber gaskets of the splints 9 are attached to the left and right sides of the drone motion camera 8. The rubber gaskets of the splints 9 increase the friction coefficient of the contact surface between the splints 9 and the drone motion camera 8, thereby improving the clamping stability of the splints 9 on the drone motion camera 8 and preventing the drone motion camera 8 from slipping from between the splints 9 during high-altitude flight.

[0024] In the disclosed embodiment, a forward threaded end and a reverse threaded end are provided on the outer side of the threaded rod 12. The forward threaded end of the threaded rod 12 is meshed and connected in the threaded through hole of the left clamping plate 9, and the reverse threaded end of the threaded rod 12 is meshed and connected in the threaded through hole of the right clamping plate 9. The threaded rod 12 drives the two groups of clamping plates 9 to move in opposite directions along the rotating shaft 20, thereby completing the clamping and releasing work of the two groups of clamping plates 9 on the drone sports camera 8. The installation operation is simple and quick.

[0025] In the disclosed embodiment, the rubber sleeve 6 is a cylindrical structure that penetrates from top to bottom, the guide column 13 is inserted into the inner side of the rubber sleeve 6 cylindrical structure, and the inner side surface of the rubber sleeve 6 cylindrical structure is attached to the outer side surface of the guide column 13. The rubber sleeve 6 increases the contact friction between the rubber sleeve 6 and the guide column 13 through the rough surface of the rubber material. The friction damping effect formed between the rubber sleeve 6 and the guide column 13 enables the rubber sleeve 6 to cooperate with the spring 15 to complete the shock absorption work between the fixed frame 1 and the shock absorbing frame 2.

[0026] In the disclosed embodiment, there are two groups of flip support plates 7. The lower side of each group of flip support plates 7 has a convex plate, and a small through-hole structure is provided on the convex plate that runs through the left and right sides. The end of the threaded rod 12 has a non-threaded surface that is rotatably connected to the small through-hole of the convex plate of the flip support plate 7. A through hole is provided on each group of flip support plates 7, and the rotating shaft 20 is welded and connected to the threaded through-hole of the flip support plate 7, so that the flip support plate 7 carries the threaded rod 12 to engage the connected clamping plate 9 and rotates around the rotating shaft 20.

[0027] In the disclosed embodiment, two groups of ear plates are symmetrically provided on the left side and the right side near the top, and each group of ear plates is provided with a through hole structure that passes through from top to bottom. The guide support rod 3 is inserted into the through hole of the shock absorber frame 2, so that the guide support rod 3 constitutes a steering limit for the shock absorber frame 2 to prevent the active bevel gear 19 from driving the driven bevel gear 17 welded to the bottom end of the fixed column 18 to rotate, causing the shock absorber frame 2 to rotate slightly, thereby ensuring the steering accuracy and stability of the drone motion camera 8.

[0028] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The X-axis rotary servo 4, Y-axis rotary servo 5, and drone sports camera 8 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0029] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
