Description

Technical Field

[0001] This utility model pertains to gimbal equipment, specifically relating to a multi-functional gimbal system that facilitates counterweight adjustment. Background Technology

[0002] A gimbal system is a support platform with rotation and pitch functions, widely used in security monitoring, drone aerial photography, industrial inspection, video shooting and other fields. Its core function is to achieve two-dimensional angle adjustment of the equipment through motor drive, thereby providing stable and flexible attitude control for the installed cameras, sensors or other loads.

[0003] In previous gimbal products, the load-bearing components of the yaw and pitch axes generally lacked a reasonable counterweight adjustment structure, leading to uneven load on the motor and accelerated bearing wear during rotation under load. Furthermore, some traditional gimbal systems employ integrated welding or injection molding solutions for their mechanical structures, which, while convenient for production, present significant limitations in terms of maintenance, replacement, and load adaptability. Therefore, to address the shortcomings of existing technologies, a multi-functional gimbal system with easily adjustable counterweights has been developed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-functional gimbal system that facilitates counterweight adjustment.

[0005] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted:

[0006] A multi-functional gimbal system with easy counterweight adjustment includes a base with a yaw motor mounted in the middle; a rotating platform positioned above and connected to the yaw motor; an adjustable bracket movably mounted on the rotating platform; and a pitch drive mechanism mounted on the top of the adjustable bracket.

[0007] Furthermore, the pitch drive mechanism includes a pitch drive motor; a rotating shaft; and a mounting base. The mounting base has a mounting port, one end of which is connected to the pitch drive motor for transmission, and the other end is connected to one end of the rotating shaft. The other end of the rotating shaft is mounted on a bearing housing.

[0008] Furthermore, the adjustable bracket includes two support frames, which are parallel and spaced apart, and are adjustablely mounted on the rotating platform.

[0009] Furthermore, the support frame includes a base; and a straight section, one end of which is bent and connected to the base, and the other end is connected to at least one overlapping section, which is adjustablely and slidably mounted on the rotating platform.

[0010] Furthermore, the present invention provides a multi-functional gimbal system for easy counterweight adjustment, which also includes a tensioning component. A groove is provided on the rotating platform for each overlapping section, the overlapping section overlaps the top of the groove, and the tensioning component passes through the overlapping section and is loosely connected to the groove.

[0011] Furthermore, the tightening component includes a capped screw and a nut, the nut being placed at the bottom of the slide groove, and the screw passing through an overlapping section, the slide groove, and the nut; wherein, when the screw is tightened, the overlapping section is fixedly connected to the rotating platform; when the screw is loosened, the overlapping section can move along the slide groove.

[0012] Furthermore, the present invention provides a multi-functional gimbal system that facilitates counterweight adjustment, which also includes a gimbal bearing and a limiting component. The limiting component is suspended and installed on the base, the gimbal bearing is embedded in the limiting component, and the rotating platform is connected to the gimbal bearing.

[0013] Furthermore, the limiting member includes a second connector, a first limiting ring, and a second limiting ring. The second limiting ring and the first limiting ring are arranged in parallel with a gap between them. The first limiting ring and the second limiting ring are installed on the rotating platform through multiple second connectors.

[0014] Furthermore, the second connecting member includes a support rod and a support, the top surface of which is provided with a platform, and the support rod is connected to the support.

[0015] Furthermore, the rotating platform includes a top support plate, a bottom plate, and third connecting members. The bottom plate has a shaft hole, and the top support plate is used to support and install the adjustable bracket. The top support plate is placed on top of the gimbal bearing, and the bottom plate is placed at the bottom of the gimbal bearing. The top support plate and the bottom plate are connected by multiple third connecting members.

[0016] The advancements of this invention compared to the prior art are as follows:

[0017] This invention provides a stable platform via a base plate, achieves horizontal rotation using a rotating platform, and incorporates an adjustable frame with a pitch drive mechanism. This allows the pitch drive motor of the pitch drive mechanism to adjust the pitch direction, forming a gimbal system with two degrees of freedom. It is suitable for scenarios requiring attitude control, such as intelligent monitoring, UAV gimbals, and target tracking applications. During use, the control system sends angle control signals to the yaw motor and pitch drive motor respectively, enabling precise angle adjustment of the rotating platform and mounting base.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0031] Example 1:

[0032] like Figures 1 to 9 As shown, this embodiment presents a multi-functional gimbal system with easy counterweight adjustment, including a base 1, a rotating platform 11, an adjustable bracket, and a pitch drive mechanism. A yaw motor 16 is installed in the middle of the base 1; the rotating platform 11 is positioned above the yaw motor 16 and is connected to the yaw motor 16 via a transmission; the adjustable bracket is movably and adjustablely mounted on the rotating platform 11; and the pitch drive mechanism is mounted on the top of the adjustable bracket.

[0033] It should be noted that the pitch drive mechanism and yaw motor 16 of this invention are both electrically connected to the control system of the gimbal system. The control system can send control signal commands to the pitch drive mechanism and yaw motor 16.

[0034] The pitch drive mechanism can adjust the pitch direction of the equipment mounted on it by looking down or looking up.

[0035] The yaw motor 16 features high speed, low noise, low power consumption, and high reliability, enabling high-precision control.

[0036] A structure for mounting the base to an application device is provided, with the addition of a first connector 2. The base 1 can be mounted to the application device via multiple first connectors 2. The number of first connectors that can be installed can be 2, 3, 4, 5, or 6, etc.

[0037] like Figure 9As shown, one structure of the first connector 2 includes a support base 21, a first nut 22 and a first screw 23. One end of the first screw 23 is installed on the support base 21 and the other end is connected to the nut 22.

[0038] When the base 1 is installed on the application device, the support base 21 is fixedly installed on the application device, and the first screw 23 passes through the base 1 and is threadedly connected to the first nut 22. When the first nut 22 is tightened, the base 1 is fixedly installed on the support base 21. When the first nut 22 is unscrewed, that is, the first nut is separated from the first screw, the base 1 can be separated from the first screw.

[0039] Understandably, the base 1 has a through hole for the first screw to pass through.

[0040] In some alternative embodiments, one structure of the pitch drive mechanism is provided. The pitch drive mechanism includes a pitch drive motor 9, a rotating shaft 7, and a mounting base 8. The mounting base 8 has a mounting port 81, one end of which is connected to the pitch drive motor 9 for transmission, and the other end is connected to one end of the rotating shaft 7, the other end of which is mounted on a bearing housing 6.

[0041] During installation, the pitch drive motor 9 is mounted on one side of the top of the adjustable bracket, while the bearing housing 6 is mounted on the other side of the top of the adjustable bracket.

[0042] One structure of the bearing housing 6 can be a flange-type bearing housing.

[0043] Mounting base 8 can rotate relative to bearing housing 6 via rotating shaft 7. When pitch drive motor 9 drives mounting base 8 to swing, mounting base 8 can swing under the action of rotating shaft 7. Mounting base can swing up and down, thus achieving overhead and under-view effects.

[0044] In some alternative embodiments, a structure for the adjustable support is provided. The adjustable support includes two support frames 5, which are parallel and spaced apart, and are adjustablely mounted on the rotating platform 11.

[0045] The support frame 5 is adjustable, meaning the distance between the two support frames on the rotating platform can be adjusted as needed.

[0046] To further stabilize the pitch drive motor 9 of the pitch drive mechanism, a mounting base 10 is added. The mounting base 10 further secures the pitch drive motor 9, which is mounted on the support frame 5. One end of the mounting base 10 is fitted with the pitch drive motor 9 of the pitch drive mechanism, and the other end is mounted on the support frame 5. The pitch drive motor 9 is further secured to the support frame 5 by the mounting base 10.

[0047] like Figure 7As shown, the base 10 is provided with multiple support legs 102, which are used for fixed connection with the support frame 5. In order to facilitate the support and installation of the pitch drive motor 9, the base 10 is provided with a slot 101. The slot 101 facilitates the installation and fixation of the pitch drive motor 9 on the base 10.

[0048] In some alternative embodiments, one structure of the support frame is provided. The support frame 5 includes a base 51 and a straight section 52. One end of the straight section 52 is bent and connected to the base 51, and the other end is connected to at least one overlapping section 54, which is adjustablely slidably mounted on the rotating platform 11.

[0049] like Figure 1 , 2 As shown, there are two support frames 5 installed. Therefore, the base of one support frame is used for the bearing seat 6, and the base of the other support frame is used to support and install the pitch drive motor 9.

[0050] In some alternative embodiments, an adjustable mounting structure for the support frame and the rotating platform is provided, with the addition of a tensioning element. A groove 111 is provided on the rotating platform 11 for each overlapping segment 54, the overlapping segment 54 overlaps the top of the groove 111, and the tensioning element passes through the groove 111 and is loosely connected to the overlapping segment 54.

[0051] In some alternative embodiments, one structure for the tensioner is provided. For example... Figure 2 As shown, the tightening component includes a capped screw 53 and a nut 55. The nut 55 is placed at the bottom of the slide groove 111. The screw 53 passes through an overlapping section 54 and is connected to the slide groove 111 and the nut 55. When the screw 53 is tightened, the overlapping section 54 is fixedly connected to the rotating platform 11. When the screw 53 is loosened, the overlapping section 54 can move along the slide groove 111.

[0052] In some optional embodiments, to ensure smooth rotation of the rotating platform, a gimbal bearing 13 and a limiting member are added. The limiting member is suspended from the base 1, the gimbal bearing 13 is embedded in the limiting member, and the rotating platform 11 is connected to the gimbal bearing 13.

[0053] The limiting component supports the installation of the gimbal bearing, which in turn supports the smooth rotation of the rotating platform. As a supporting structure, the limiting component not only raises the rotating platform above the top surface of the base 1, but also shares the vertical load of the rotating platform, thereby reducing the vertical load applied to the yaw motor and providing protection for the yaw motor during startup.

[0054] It should be noted that the gimbal bearing can be a rolling bearing structure. A bearing typically consists of an inner ring and an outer ring. The rotating platform overlaps with the inner ring. The rotating platform can rotate smoothly under the support of the inner ring.

[0055] In some optional embodiments, one structure of the limiting member is provided. The limiting member includes a second connecting member 3, a first limiting ring 4, and a second limiting ring 15. The second limiting ring 15 and the first limiting ring 4 are arranged in parallel with a gap between them. The first limiting ring 4 and the second limiting ring 15 are mounted on the rotating platform 11 by multiple second connecting members 3.

[0056] like Figure 1 , 4 As shown, the second limiting ring 15 and the first limiting ring 4 can be structured as planar rings. Multiple through holes are provided on the ring for the second connector to pass through.

[0057] This embodiment further provides a structure for the second connector. For example... Figure 8 As shown, the second connecting member 3 includes a support rod 31 and a support 32. The bottom of the support 32 is fixedly installed on the base 1, and the top surface is provided with a platform 321. The second limiting ring 15 and the first limiting ring 4 are arranged in parallel at intervals. The support rod 31 extends through the through holes on the second limiting ring 15 and the first limiting ring 4 and is inserted into the support 32.

[0058] One structure of the support rod 31 can be a capped screw.

[0059] One connection structure for the support rod 31 is that the support rod 31 is threadedly connected to the second limiting ring 15, the first limiting ring 4, and the support 32. Another structure for the support rod 31 is that the support rod 31 is threadedly connected to the second limiting ring 15 and the first limiting ring 4, and the support rod is inserted into the support 32, with a tight fit between the support rod and the support. Both structures allow for detachable connections between the support rod and the second limiting ring 15, the first limiting ring 4, and the support 32.

[0060] Understandably, the support 32 can be vertically installed on the base 1. Under the action of the support, the first limiting ring is higher than the top surface of the base, creating a height difference between the first limiting ring and the top surface of the base. This raises the height of the gimbal bearing.

[0061] like Figure 1 , 4 As shown, the first limiting ring 4 is attached to the bearing platform 321 on the top of the support 32.

[0062] The second limiting ring 15 and the first limiting ring 4 are sleeved parallel to each other on the gimbal bearing. To prevent axial movement of the gimbal bearing, limiting blocks 14 are added. Multiple limiting blocks 14 are circumferentially distributed along the top edge of the inner circle of the first limiting ring 4. Multiple limiting blocks 14 are circumferentially distributed along the bottom edge of the inner circle of the second limiting ring 15. The multiple limiting blocks 14 on the first limiting ring 4 and the second limiting ring 15 together restrict and support the gimbal bearing. The multiple limiting blocks can provide radial limiting support for the gimbal bearing. When the gimbal bearing receives a radial force, the multiple limiting blocks 14 on the first limiting ring 4 and the second limiting ring 15 provide radial support and limit the gimbal bearing, preventing axial movement of the gimbal bearing 13 due to external forces, and ensuring that the gimbal bearing remains at the horizontal rotation center.

[0063] In some optional embodiments, the rotating platform 11 includes a top support plate 112, a bottom plate 113, and third connecting members 12. The bottom plate 113 has a shaft hole, and the top support plate 112 is used to support the installation of an adjustable bracket. The top support plate 112 is placed on top of the gimbal bearing 13, and the bottom plate 113 is placed at the bottom of the gimbal bearing 13. The top support plate 112 and the bottom plate 113 are connected by multiple third connecting members 12.

[0064] One possible structure for the third connector 12 is a bolt.

[0065] like Figure 1 , 4 As shown in Figure 6, the top of the top support plate 112 has at least one groove 111. Each groove corresponds to an overlap section 54 on the adjustable bracket.

[0066] During installation, the top bearing plate 112 and the base plate 113 are clamped and fixed to the inner ring of the gimbal bearing 13 by multiple third connectors. The yaw axis of the yaw motor 16 passes through the shaft hole in the base plate and is connected to the base plate 113 for transmission. The yaw motor 16 drives the output shaft to rotate, which in turn drives the base plate 113 to rotate. The base plate 113 drives the top bearing plate 112 for transmission through multiple third connectors 12. Under the action of the inner ring of the gimbal bearing 13, the output shaft can drive the top bearing plate 112 and the base plate to rotate smoothly. Thus, the rotating platform 11 rotates with the yaw axis of the yaw motor 16, so that the rotating platform can be used to adjust the horizontal direction of the gimbal.

[0067] Understandably, the top bearing plate 112 and the bottom plate are provided with corresponding through holes for the third connector to pass through. The third connector can connect and fix the top bearing plate 112 and the bottom plate 113 through the through holes.

[0068] To facilitate the quick positioning and installation of the top and bottom bearing plates onto the inner ring of the gimbal bearing 13, such as... Figure 6As shown, multiple positioning blocks 114 are circumferentially spaced and installed on both the top bearing plate 112 and the bottom plate 113. During installation, the multiple positioning blocks 114 on the top bearing plate 112 and the bottom plate 113 are attached to the inner wall of the inner ring of the gimbal bearing 13. Through the positioning action of the multiple positioning blocks, the top bearing plate 112 and the bottom plate 113 can be quickly positioned and installed on the inner ring of the gimbal bearing 13.

[0069] The rotating platform is the core component of yaw angle control. Its structure consists of two layers, with a high-precision gimbal bearing sandwiched in between. The gimbal bearing provides low-friction, high-stability rotational support, ensuring smooth horizontal rotation of the gimbal. Even during high-speed rotation of the platform, the gimbal bearing maintains extremely low vibration. Secondly, bearing positioning blocks are installed on the rotating platform to ensure that the gimbal bearing does not deviate from the center of rotation. The rotating platform also features a slide for mounting the vertical support. This slide allows for forward and backward adjustment of the two adjustable supports, enabling the position of the adjustable supports to be adjusted according to actual application requirements. This optimizes the center of gravity distribution, thereby optimizing the overall weight distribution of the gimbal, minimizing the motor load, and improving control accuracy.

[0070] The adjustable bracket is the load-bearing structure for pitch angle motion, used to fix the pitch drive motor and provide vertical rotation axis support. The bottom of the adjustable bracket is connected to the rotating platform and its position can be adjusted within a groove to adapt to different load requirements. The design of the adjustable bracket fully considers counterweight optimization, ensuring that the pan-tilt head maintains good balance under different equipment installation conditions. The adjustable bracket can be adjusted within a certain range within the groove on the rotating platform, making the center of gravity of the overall structure connected to the adjustable bracket more central, reducing rotational inertia, and improving control accuracy.

[0071] Understandably, the pitch drive motor is mounted on the rotating platform via an adjustable bracket. A mounting base and the pitch drive motor are installed between the two adjustable brackets. The distances between the mounting base and the two adjustable brackets are unequal; the side of the mounting base where the pitch drive motor is mounted has a larger gap from the adjustable bracket. This allows the pitch drive motor to be closer to the center of the rotating platform, reducing inertial impact during horizontal movement.

[0072] Both the pitch drive motor and the yaw motor utilize MR-3515 brushless servo motors, characterized by high torque, low noise, and high precision. The pitch motor is fixed to a vertical support, enabling pitch angle adjustment. The yaw motor is mounted below the rotating platform, driving the platform to rotate horizontally.

[0073] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
