[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0035] The following is for reference. Figures 1 to 9 This describes the gimbal rotation structure according to an embodiment of the present utility model.
[0036] According to an embodiment of the present utility model, the gimbal rotation structure includes a rotating shell 100 and a connecting arm 200. The connecting arm 200 is disposed at one end of the rotating shell 100 and is rotatably connected to the rotating shell 100.
[0037] The surfaces of the rotating shell 100 and the connecting arm 200 that abut each other are provided with a plurality of matching rotating protrusions 110, and a rotating groove 120 is formed between adjacent rotating protrusions 110. When the rotating protrusions 110 of the connecting arm 200 and the rotating grooves 120 of the rotating shell 100 are interlocked, the rotation of the connecting arm 200 relative to the rotating shell 100 is restricted. When the connecting arm 200 rotates relative to the rotating shell 100, one rotating protrusion 110 rotates from one rotating groove 120 to the next rotating groove 120.
[0038] For example Figure 1 , Figure 5 and Figure 8As shown, the gimbal rotation structure includes a rotating shell 100 and a connecting arm 200. The connecting arm 200 is disposed on the top of the rotating shell 100 and rotatably connected to it. Multiple matching rotating protrusions 110 are evenly distributed around the rotation center on the contact surfaces of the rotating shell 100 and the connecting arm 200, and rotating grooves 120 are formed between adjacent rotating protrusions 110. The rotating protrusions 110 and rotating grooves 120 of the connecting arm 200 and the rotating shell 100 are interlocked. The rotating protrusions 110 on the connecting arm 200 are inserted into the rotating grooves 120 on the rotating shell 100, and the rotating protrusions 110 on the rotating shell 100 are inserted into the rotating grooves 120 on the connecting arm 200, thereby restricting the connecting arm 200 from rotating freely relative to the rotating shell 100. The rotating protrusion 110 will slide from one rotating groove 120 into the next rotating groove 120 only when an external force is applied to rotate the connecting arm 200. Without the application of an external force, the position between the connecting arm 200 and the rotating shell 100 remains stable.
[0039] By replacing traditional rolling bearings with mechanical limiting structures, the number of parts is reduced and the assembly process is simplified; the embedded relationship between the rotating protrusion 110 and the rotating groove 120 can achieve precise positioning, avoid the ambiguity of rotation in traditional structures, and improve the user's operating experience.
[0040] In some specific embodiments of this utility model, the rotating protrusion 110 and the rotating groove 120 are V-shaped and compatible.
[0041] This embodiment further defines the shapes of the rotating protrusion 110 and the rotating groove 120 as a matching V-shape. The two inclined surfaces of the V-shaped structure form a wedge fit. When the connecting arm 200 is rotated under force, the rotating protrusion 110 slides along the inclined surface of the rotating groove 120 and automatically engages with the next groove after it is in place.
[0042] The V-shaped structure provides a clear mechanical stop, resulting in higher positioning accuracy. The crisp "click" feedback confirms that the rotation is in place, making it suitable for scenarios requiring precise angle control, such as the turning of a live streaming camera.
[0043] In some other specific embodiments of this utility model, the rotating protrusion 110 and the rotating groove 120 are in the shape of matching arcs.
[0044] In this embodiment, the shapes of the rotating protrusion 110 and the rotating groove 120 are further defined as matching arc shapes. The contact surface of the arc-shaped structure is a smooth curved surface, and the protrusion can smoothly transition along the curved surface of the groove when the connecting arm 200 rotates, reducing frictional resistance.
[0045] The curved design reduces mechanical wear during rotation and extends the life of the structure; the rotation is smoother and more suitable for scenarios that require frequent angle adjustments, such as dynamic shooting and focusing.
[0046] In some specific embodiments of this utility model, the top of the rotating shell 100 is provided with a rotating shaft 130 protruding outward, and the bottom of the connecting arm 200 is provided with a first receiving groove 210. The rotating shaft 130 is inserted into the first receiving groove 210, forming a structure in which the connecting arm 200 and the rotating shell 100 are rotatably connected.
[0047] For example Figure 3 , Figure 6 and Figure 7 As shown, a rotating shaft 130 protrudes outward from the top of the rotating shell 100, and a coaxial first receiving groove 210 is formed at the bottom of the connecting arm 200. The first receiving groove 210 is fitted onto the rotating shaft 130 to form a rotating pair. This structure enables the coaxial rotation of the connecting arm 200 and the rotating shell 100 through shaft-hole mating.
[0048] The shaft-hole mating structure is simple and compact, requiring no additional fasteners and reducing assembly complexity; the coaxial design ensures smooth rotation and avoids radial wobble.
[0049] In some specific embodiments of this utility model, the rotating shaft 130 is hollow inside and a second receiving groove 131 is provided. A limiting post 211 is provided in the first receiving groove 210. The limiting post 211 is inserted into the second receiving groove 131 so that the connecting arm 200 is rotatably connected to the rotating shell 100.
[0050] For example Figure 3 , Figure 6 and Figure 7 As shown, the rotating shaft 130 has a hollow interior forming a second receiving groove 131. The first receiving groove 210 of the connecting arm 200 has a limiting post 211 coaxial with the rotating shaft 130 at its center. The second receiving groove 131 is sleeved on the limiting post 211. The cooperation between the limiting post 211 and the second receiving groove 131 restricts the axial displacement of the connecting arm 200 while allowing it to rotate around the shaft.
[0051] The nested structure achieves the dual functions of axial limiting and circumferential rotation, avoiding the cumbersome assembly of traditional multi-part combinations; the coaxial design of the limiting post 211 and the rotating shaft 130 ensures rotational accuracy.
[0052] In some specific embodiments of this utility model, the rotating protrusion 110 and / or the rotating groove 120 on the rotating shell 100 are arranged around the rotating shaft 130; the rotating protrusion 110 and / or the rotating groove 120 on the connecting arm 200 are arranged around the first receiving groove 210.
[0053] For example Figure 5 and Figure 8As shown, the rotating protrusion 110 and rotating groove 120 on the rotating shell 100 are arranged around the rotating shaft 130, and the rotating protrusion 110 and rotating groove 120 on the connecting arm 200 are arranged around the first receiving groove 210. They cooperate with each other to enable the rotating shell 100 to rotate relative to the connecting arm 200.
[0054] In some specific embodiments of this utility model, a spring 212 is also provided in the second receiving groove 131. A limiting plate 213 is provided at the bottom of the limiting post 211. The spring 212 is compressed and sleeved on the limiting post 211, with one end abutting against the limiting plate 213 and the other end abutting against the top wall of the rotating shaft 130. The spring 212 is used to drive the rotating shell 100 to press the connecting arm 200.
[0055] For example Figure 3 and Figure 7 As shown, a spring 212 is installed in the second receiving groove 131, and a limiting plate 213 is provided at the bottom of the limiting post 211. The spring 212 is compressed and sleeved on the limiting post 211, with one end abutting against the limiting plate 213 and the other end abutting against the top wall of the rotating shaft 130. When the connecting arm 200 rotates, the spring 212 is further compressed or released, providing a rebound force.
[0056] When the connecting arm 200 rotates relative to the rotating shell 100, after the rotating protrusion 110 passes the highest point of the rotating groove 120, it is pressed by the rebound force provided by the spring 212 towards the lowest point of the rotating groove 120, automatically completing the locking in place, and pressing the rotating shell 100 onto the connecting arm 200, making the connection between the rotating shell 100 and the connecting arm 200 more stable.
[0057] In some specific embodiments of this utility model, the connecting arm 200 is provided with a connecting portion 230 for connecting the clamping portion 220.
[0058] For example Figure 1 , Figure 2 and Figure 3 As shown, the connecting arm 200 is provided with a connecting part 230 for connecting the clamping part 220. The connecting part 230 can be connected to the clamping part so that the clamping part 220 can clamp other shooting equipment.
[0059] For example Figure 1 As shown, the connecting arm 200 is provided with a clamping part 220 for fixing external devices such as mobile phones and cameras. The clamping part 220 can take the form of a flexible clamping arm, a threaded interface, etc., to adapt to devices of different sizes.
[0060] The integrated clamping unit 220 eliminates the need for additional accessories and simplifies the equipment installation process; the clamping structure is linked with the connecting arm 200 to ensure that the shooting equipment rotates synchronously with the gimbal, resulting in greater stability.
[0061] In some specific embodiments of this utility model, a camera 600 is provided on the rotating shell 100. The camera 600 is rotatably connected to the rotating shell 100 and performs pitching motion along the axial direction of the rotating shell 100.
[0062] For example Figure 1 , Figure 2 and Figure 3 As shown, a camera 600 is mounted on the rotating housing 100. The camera 600 is rotatably connected to the rotating housing 100 and can tilt along the axis of the rotating housing 100 to adjust the shooting angle. The camera 600 can have a built-in image processing module to support real-time image transmission.
[0063] The integrated camera 600 design allows the gimbal to function as both a support and a shooting device, reducing equipment stacking; the tilt adjustment function covers a wider shooting range to meet the shooting needs of various scenarios.
[0064] In some specific embodiments of this utility model, a rotating groove 140 is provided on the rotating shell 100, and a rotating rod 610 is provided protruding from the side of the camera 600. The rotating rod 610 is disposed in the rotating groove 140 so that the camera 600 is rotatably connected to the rotating shell 100.
[0065] For example Figure 9 As shown, a fixing member is provided on the rotating shell 100, and a rotating groove 140 is provided on both sides of the fixing member. A rotating rod 610 is provided on both sides of the camera 600. The rotating rod 610 is rotatably disposed in the rotating groove 140, so that the camera 600 can be rotatably connected to the rotating shell 100, so that the camera 600 can make pitch movement along the axis of the rotating shell 100 to realize the shooting angle adjustment.
[0066] In some specific embodiments of this utility model, a support base 300 and a drive motor 400 are also included. A rotating part 310 is provided on the support base 300 and is connected to the rotating shell 100. The drive motor 400 is disposed inside the rotating shell 100 and is connected to the rotating part 310, and is used to drive the rotating part 310 to rotate relative to the support base 300.
[0067] For example Figure 2 , Figure 3 and Figure 4 As shown, the gimbal includes a support base 300 and a drive motor 400. The support base 300 is provided with a rotating part 310, which is connected to the rotating shell 100. The drive motor 400 is placed inside the rotating shell 100 and is connected to the rotating part 310 for transmission, and can drive the rotating part 310 to rotate relative to the support base 300.
[0068] The support base 300 is equipped with multiple retractable and expandable supports to support the entire gimbal.
[0069] The drive motor 400 enables automated control of the gimbal's horizontal rotation, suitable for scenarios such as live streaming and panoramic shooting, reducing the intensity of manual operation; the bracket base 300 provides stable support and improves the overall structural reliability.
[0070] The configuration of the drive motor 400 and the rotating part 310 allows the gimbal to have both manual and electric rotation modes. In the case of manual rotation, the connecting arm 200 and the rotating shell 100 can be rotated manually, at which time the shell and the support base 300 are relatively stationary. In the case of electric rotation, the drive motor 400 can drive the rotating part 310 to rotate, so that the rotating shell 100 rotates relative to the support base 300. At this time, the connecting arm 200 and the rotating shell 100 rotate synchronously, thus realizing the electric rotation of the connecting arm 200 relative to the support base 300.
[0071] Furthermore, it also includes a handle 500, which is rotatably connected to the rotating face shell 100 and can make pitching motion along the axial direction of the rotating face shell 100. A detachable remote control 510 is provided on the handle 500.
[0072] For example Figure 1 As shown, the handle 500 is rotatably connected to the rotating face shell 100 and can tilt along the axis of the rotating face shell 100; a detachable remote control 510 is provided on the handle 500, which is connected to an external device via Bluetooth to control shooting parameters such as focal length and shutter speed.
[0073] The tilt adjustment function of the handle 500 expands the operational dimensions of the gimbal and adapts to different shooting angles; the detachable remote control 510 enables long-distance control and improves user convenience.
