Description

Technical Field

[0001] This utility model relates to the field of gimbal rotation mechanism technology, specifically a compact gimbal rotation mechanism. Background Technology

[0002] Professional gimbals designed for high-end video conferencing applications need to achieve multi-directional stable shooting and portable design, the core of which lies in innovative coaxial steering structure and compact drive layout.

[0003] Most existing gimbals use traditional gearbox motors to drive the central gear to rotate, thereby driving the overall movement of the gimbal.

[0004] However, traditional horizontal rotation mechanisms require dual drive motors, resulting in slight aesthetic defects, specifically a thicker base and larger overall size, making them inconvenient to carry and place. Therefore, we propose a compact gimbal rotation mechanism to address the aforementioned issues. Utility Model Content

[0005] The purpose of this utility model is to provide a compact gimbal rotation mechanism to solve the problem that the existing horizontal rotation mechanism mentioned in the background art has slight defects in appearance due to the need for dual drive motors, specifically manifested in the thicker base, larger overall size, and inconvenience in carrying and placing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compact gimbal rotation mechanism, comprising a horizontal fixing member, with motors installed on both sides of the lower end of the horizontal fixing member. The output end of one motor extends through and to the upper end of the horizontal fixing member and is equipped with a horizontal adjusting helical gear. The output end of the other motor extends through and to the upper end of the horizontal fixing member and is equipped with a vertical adjusting helical gear. A horizontal center tooth is provided on one side of the horizontal adjusting helical gear. A bearing seat is provided below the horizontal center tooth. A spring washer and a second bearing are sequentially installed inside the bearing seat and connected to the horizontal fixing member by screws. A base is installed at the lower end of the bearing seat. A vertical support arm is installed at the rear end of the horizontal fixing member. A first bearing is installed inside both ends of the vertical support arm. A coaxial tooth is installed inside the lower first bearing. A face tooth is installed at the front end of the coaxial tooth. A lens is provided at the front end of the upper first bearing. A pulley is provided at the rear end of the upper first bearing. The lens is connected to the pulley by screws. The pulley is connected to the coaxial tooth drive by a synchronous belt.

[0007] Preferably, the line connecting the centers of the motors on both sides passes through the center of the central hole of the horizontal fixing member.

[0008] Preferably, the first bearing is connected to the vertical support arm via a bearing clamp.

[0009] Preferably, the horizontal adjusting helical gear is meshed with the horizontal center gear for transmission.

[0010] Preferably, the vertical adjusting helical gear is connected to the face gear meshing transmission.

[0011] Preferably, a spacer ring is provided on the inner side of the bearing housing.

[0012] Preferably, the horizontal adjusting helical gear and the vertical adjusting helical gear have the same specifications.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The gear used for motor transmission in this utility model is helical, which increases the gear meshing overlap and improves the stability of the gimbal.

[0015] (2) The two rotating shafts of the vertical and horizontal transmission structure of this utility model are equipped with two bearings in the same axis, which eliminates some bearing clearance and ensures that the gimbal operates more smoothly in the horizontal and vertical coaxial directions.

[0016] (3) In the gimbal rotation structure of this utility model, both motors are placed horizontally with the output shaft facing upward. This motor layout improves space utilization.

[0017] (4) The gimbal rotation structure of this utility model uses the same specification for the two motor helical teeth, which reduces the types of parts, makes processing and assembly simpler, and thus reduces costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-3 This utility model provides an embodiment of a compact gimbal rotation mechanism, including a horizontal fixing member 1. Motors 3 are installed on both sides of the lower end of the horizontal fixing member 1. The output end of one motor 3 extends through and to the upper end of the horizontal fixing member 1, and is equipped with a horizontal adjusting helical gear 2. The output end of the other motor 3 extends through and to the upper end of the horizontal fixing member 1, and is equipped with a vertical adjusting helical gear 15. A horizontal center tooth 16 is provided on one side of the horizontal adjusting helical gear 2. A bearing seat 4 is provided below the horizontal center tooth 16. A spring washer 14 and a second bearing 18 are sequentially installed inside the bearing seat 4 and connected to the horizontal fixing member 1 by screws. A base 5 is installed at the lower end of the bearing seat 4, and a vertical adjustment helical gear 15 is installed at the rear end of the horizontal fixing member 1. The straight support arm 12 and the vertical support arm 12 are both equipped with first bearings 8. The lower first bearing 8 is equipped with a coaxial gear 7. The front end of the coaxial gear 7 is equipped with a face gear 6. The front end of the upper first bearing 8 is equipped with a lens 13. The rear end of the upper first bearing 8 is equipped with a pulley 11. The lens 13 is connected to the pulley 11 by screws. The pulley 11 is connected to the coaxial gear 7 by a synchronous belt 10. The center line of the two motors 3 passes through the center hole of the horizontal fixing part 1. The first bearing 8 is connected to the vertical support arm 12 by a bearing pressure block 9. The horizontal adjusting helical gear 2 is meshed with the horizontal center gear 16 for transmission. The vertical adjusting helical gear 15 is meshed with the face gear 6 for transmission. The inner side of the bearing seat 4 is equipped with a spacer 17.

[0024] During assembly, first, place the spring pad 14 and the second bearing 18 sequentially inside the bearing seat 4 to form assembly a. Then, install the horizontal adjusting helical gear 2 and the vertical adjusting helical gear 15 on the two motors 3 respectively and tighten them with screws. Place the two motors 3 parallel so that the center line connecting the two motors 3 passes through the center hole of the horizontal fixing part 1 to form assembly b. Combine assembly a with the horizontal fixing part 1 and tighten it with screws. Combine assembly b with the horizontal fixing part 1 and tighten it with screws to form assembly c. Place the first bearing 8 inside the bearing pressure block 9 to form assembly d. Fasten assembly d onto the vertical support arm 12 and tighten it with screws. A total of three assemblies d are required, two of which are locked opposite each other on the vertical support arm 12. Finally, install the face tooth 6 and the coaxial tooth 7 opposite each other and tighten them with screws to form the assembly. Assembly e is vertically fastened to the horizontal fixing part 1 of assembly c and locked with screws to form assembly f. The horizontal center tooth 16 is passed through the bearing seat 4 of assembly f, and the spacer 17 is placed in the bearing seat 4 of assembly f. Finally, the base 5 is installed below the bearing seat 4 and locked with the horizontal center tooth 16 by screws to form assembly g. The pulley 11 is placed in the reserved hole on assembly g, and the pulley 11 and the coaxial tooth 7 on assembly g are connected by the synchronous belt 10. Finally, the lens 13 is connected to the pulley 11 by screws to complete the assembly. In this gimbal rotation structure, the horizontal direction is achieved by the engagement of the helical gear and the horizontal center tooth 16, and the vertical direction is achieved by the engagement of the helical gear and the face tooth 6, so as to realize the horizontal and vertical rotation of the gimbal mechanism. The use of helical gears has a higher overlap ratio than straight gears, resulting in smoother transmission and lower noise.

[0025] Furthermore, the horizontal adjusting helical gear 2 and the vertical adjusting helical gear 15 have the same specifications, reducing the number of parts and simplifying processing and assembly, thereby reducing costs.
