[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] like Figures 1 to 8 As shown, this embodiment provides a gimbal camera device applicable to fields such as cameras and camcorders. In some embodiments, the gimbal camera device includes a lens barrel 1, a drive component 2, a lens 3, a rotating component 6, a fixing component 4, and a flexible component 5. The drive component 2 is fixed inside the lens barrel 1; the lens 3 is located inside the lens barrel 1, with one end of the lens 3 fixedly connected to the output end of the drive component 2 and the other end rotatably connected to the lens barrel 1; the drive component 2 is used to drive the lens 3 to rotate around its axis; the drive component 2 and the lens 3 are connected by the fixing component 4, and a limiting part 14 is provided on the inner wall of the end of the lens barrel 1 rotatably connected to the lens 3, with the end face of the rotating component 6 abutting against the limiting part 14; the flexible component 5 is disposed inside the lens barrel 1, between the lens barrel 1 and the fixing component 4. Specifically, the flexible component 5 is made of silicone or rubber, and the lens 3 is rotatably connected to the lens barrel 1 via the drive component 2. The drive component 2 can be a motor, with its output end connected to the lens 3, and the motor speed can be controlled by controlling the current of the motor. In other embodiments, the flexible component 5 can also be made of plastic, but is not limited thereto.

[0033] The driving component 2 allows the lens 3 to rotate around its axis within the lens barrel 1. The driving component 2 is fixed inside the lens barrel 1. One end of the lens 3 is fixedly connected to the driving component 2, and the other end is rotatably connected to the lens barrel 1, ensuring that the lens 3 can rotate normally without eccentricity. The driving component 2 and the lens barrel 1 are connected by a fixing component 4, allowing the lens 3 to be positioned inside the lens barrel 1 and rotate around its axis. A flexible component 5 is located between the lens barrel 1 and the fixing component 4, preventing excessive constraint on the driving component 2 when fixed to the lens barrel 1. This makes the rotation of the driving component 2 more stable, thus making the rotation of the lens 3 more stable. This ensures that the lens 3 does not become eccentric during rotation and that there is no internal stress on the lens 3, thereby ensuring image quality. Furthermore, the connection structure between the lens 3 and the lens barrel 1 is simple and easy to operate.

[0034] like Figure 3 , Figure 5 and Figure 6 As shown, to allow the lens 3 to rotate more smoothly within the lens barrel 1, the gimbal camera device also includes a rotating component 6. A limiting part 14 is provided on the inner wall of the end of the lens barrel 1 that is rotatably connected to the lens 3, and the end face of the rotating component 6 abuts against the limiting part 14. Specifically, the rotating component 6 is a bearing; one end face of the bearing abuts against the limiting part 14, and the other side is fixed to the lens barrel 1 with adhesive. The rotating component 6 reduces friction between the lens 3 and the lens barrel 1, protecting both and extending their service life. After wear occurs due to rotation, only the rotating component 6 needs to be replaced (i.e., the rotating component 6 and the inner wall of the lens barrel 1 are detachably connected), without needing to replace the lens 3 or the lens barrel 1, thus saving costs. The inner ring of the rotating component 6 mates with the lens 3, and the outer ring of the rotating component 6 connects to the inner wall of the lens barrel 1.

[0035] In this application, the rotating component 6 not only supports the lens 3 but also ensures the coaxiality of the lens 3 and the lens barrel 1, preventing eccentricity between the lens 3 and the lens barrel 1 during both stationary and rotating processes, thus improving the rotational accuracy of the lens 3. Furthermore, the use of the rotating component 6 in this application, which supports the lens 3 while ensuring coaxiality between the lens 3 and the lens barrel 1, eliminates the need for an L-shaped adapter, resulting in a simple component structure and convenient processing and assembly. "Improved rotational accuracy" refers to the significant increase in the coincidence between the actual rotation axis and the ideal optical axis when lens 3 rotates around its own optical axis. Radial runout and axial slippage are suppressed, and there is no eccentricity deviation in both stationary and rotating conditions. Rotational accuracy includes radial rotational accuracy (i.e., the deviation of any point on the outer ring of lens 3 from the standard circular trajectory is minimal during one rotation of lens 3 (no wobbling, no radial eccentricity)) and axial rotational accuracy (i.e., lens 3 does not slip back and forth along the optical axis during rotation, and there is no axial displacement deviation).

[0036] The mechanism by which the rotating component 6 prevents the lens 3 and lens barrel 1 from becoming misaligned during both stationary and rotating processes is as follows: Axial limiting constraint: A limiting part is provided on the inner wall of the lens barrel 1, and the end face of the rotating part 6 abuts against the limiting part 14 to limit the lens 3 and the rotating part 6 to move back and forth along the optical axis, thereby eliminating the rotational offset caused by the axial clearance. Radial centering load: The rotating part 6 is a bearing structure, with the inner ring fitting the lens 3 and the outer ring fitting the lens barrel 1, providing uniform ring support. The weight of the lens 3 and the rotational load are evenly distributed by the rotating part 6, ensuring that the lens 3 and the lens barrel 1 are coaxial. Stability under both static and dynamic operating conditions (static state and dynamic rotation): In the static state, the rotating part 6 and the limiting part 14 provide dual positioning for the lens barrel 3, and the lens 3 will not tilt or become eccentric due to its own weight; in the dynamic rotation, the rolling friction of the rotating part 6 replaces the hard friction, the rotation is smooth, and there will be no axial drift due to gaps or force offset.

[0037] In summary, the limiting part 14 abuts against the end face of the rotating part 6, only axially limiting the rotating part 6 to prevent it from moving along the axis of the lens 3 towards the drive part 2, thus stabilizing the distance between the front support points. The limiting part 14 does not restrict the radial movement space of the outer ring of the rotating part 6, and can cooperate with the rear flexible part 5 to absorb the accumulated tolerance of the assembly and release the internal stress of the assembly. At the same time, the axial load of the lens 3 is transmitted to the limiting part 14 through the rotating part 6 and is borne by the lens barrel 3, avoiding the axial force from acting directly on the output shaft of the drive part 2 and causing the shaft to be deformed under pressure. This ensures the stability of the front and rear double support points of the lens 3, further avoids the rotational eccentricity of the lens 3, ensures the smooth rotation of the lens 3 around the axis, and improves the imaging stability.

[0038] In summary, this application adds a rotating component 6 sleeved on the end of the lens 3 furthest from the driving component 2, and sets a flexible component 5 between the driving component 2 and the fixed component 4. The front end of the lens 3 can adapt to the machining error of the parts and the positional offset caused by the assembly of the flexible component 5 at the rear end with the help of the rotating component 6. The front and rear cooperation of the rotating component 6 and the flexible component 5 can absorb the accumulated assembly stress of the entire assembly chain, so as to avoid the over-constraint problem caused by the multi-point rigid constraint of the lens barrel 1, the driving component 2, and the lens 3. The rear end of the lens 3 is fixed by the driving component 2 and the front end is supported by the rotating component 6 to form a double fulcrum support, which can share the weight of the heavy lens 3 and avoid the load being concentrated on the output shaft of the driving component 2. The rotating component 6 converts the sliding friction between the lens 3 and the lens barrel 1 into rolling friction, reducing the rotational resistance of the lens 3. With the buffering effect of the rear flexible component 5, the front rotating component 6 can slightly adapt to the assembly tolerance, release the accumulated stress of the assembly chain, further prevent the lens 3 from rotating eccentrically, ensure the lens 3 rotates smoothly around the axis, effectively improve the stability of the gimbal's Roll axis operation and the imaging effect, and only the rotating component needs to be replaced when wear occurs in the later stage, resulting in lower maintenance costs.

[0039] Specifically, this application uses a flexible member 5 located between the fixed member 4 and the lens barrel 1 to assemble and fix the drive member 2 and the lens barrel 1. The clamping force generated by the locking of the fixed member 4 is absorbed and buffered by the elastic deformation of the flexible member 5, which can offset the residual stress caused by the part processing error and the assembly locking, and avoid the over-constraint problem caused by the lens barrel 1, drive member 2, lens 3, rotating member 6 and assembly error. One end of the lens 3 is fixedly connected to the output end of the drive member 2, and the other end rotates and cooperates with the lens barrel 1 to form a double-support structure. Under the drive of the drive member 2, the lens can rotate smoothly along its own axis, effectively preventing the heavy-load lens 3 from rotating eccentrically, eliminating the internal assembly stress of the lens 3, and absorbing the clamping force generated by the locking of the fixed member (4), ensuring the smooth rotation of the lens 3 and the stability accuracy with the gimbal Roll axis, and optimizing the imaging quality.

[0040] Please see Figure 6 and Figure 9 In some embodiments, the fixing member 4 includes a stop portion 42 and a connecting rod 43 connected to the stop portion 42. The flexible member 5 is sleeved on the connecting rod (43) and is limited and clamped between the stop portion 42 and the connecting portion 12. The end of the connecting rod 43 away from the stop portion 42 is detachably connected to the driving member 2 to fix the lens barrel 1 and the driving member 2. Thus, by designing the fixing member 4 to include a stop portion 42 and a connecting rod 43, this application can not only achieve bidirectional limiting of the flexible member 5 in the axial and radial directions to prevent the flexible member 5 from easily shifting, deviating, or falling off, and ensure that the flexible member 5 is subjected to uniform force and has a continuous and stable buffering effect; it can also achieve a fixed connection between the lens barrel 1 and the driving member 2.

[0041] In some embodiments, the connecting part 12 is provided with a through hole 121, the driving member 2 is provided with a first connecting hole 21, and the connecting rod 43 passes through the flexible member 5 and the through hole 121 in sequence, and is threadedly connected to the first connecting hole 21. The fixing member 4 of this application is connected to the lens barrel 1 and the driving member 2 through a shaft hole, which can reduce the difficulty of installing and disassembling the fixing member 4 to the lens barrel 1 and the driving member 2.

[0042] In some embodiments, the connecting rod 43 includes a first connecting portion 431 and a second connecting portion 432. The two ends of the first connecting portion 431 are respectively connected to a stop portion 42 and the second connecting portion 432. The radial dimension of the stop portion 42 is larger than the radial dimension of the first connecting portion 431, and the radial dimension of the first connecting portion 431 is larger than the radial dimension of the second connecting portion 432. The flexible member 5 is sleeved on the first connecting portion 431, and the first connecting portion 431 is at least partially received within the through hole 121. The second connecting portion 432 is threadedly connected to the first connecting hole 21. That is, the first connecting portion 431 is a smooth rod section without threads, while the second connecting portion 432 has threads.

[0043] In the above technical solution, the fixing member 4 adopts a three-stage stepped structure consisting of a stop part 42, a first connecting part 431, and a second connecting part 432, forming a differentiated three-section variable diameter structure with the outer diameter of the stop part 42 > the outer diameter of the first connecting part 431 > the outer diameter of the second connecting part 432; the flexible member 5 is sleeved on the middle first connecting part 431 and is limited and clamped between the stop part 42 and the connecting part 12. The axial and radial bidirectional limiting of the flexible member 5 is achieved by relying on the size difference of the three steps, so as to prevent the flexible member 5 from easily moving, deviating and falling off, and ensuring that the flexible member 5 is subjected to uniform force and the buffering effect is continuous and stable. During locking assembly, the connecting part 12 is fitted onto the first connecting part 431, and the second connecting part 432 is threadedly locked to the driving component 2. The tightening force is transmitted along the connecting rod 43 to the stop part 42 and squeezes the intermediate flexible component 5. The elastic deformation of the flexible component 5 absorbs the locking pressure and the accumulated tolerances of the parts processing and assembly. The first connecting part 431, which is housed in the through hole 121, and the inner wall of the through hole 121 have a reserved assembly gap, so that the driving component 2 can achieve a small radial adaptive displacement after assembly. This eliminates the risk of over-constraint caused by lens barrel 1, driving component 2, lens 3, rotating component 6, and assembly errors from the installation end. The three-section fixing component 4, together with the flexible component 5 and the rotating component 6, enables the gimbal camera equipment to release the residual internal stress of the whole assembly in a coordinated manner, preventing the heavy-duty lens 3 from rotating eccentrically due to the assembly stress, ensuring the smooth operation of the driving component 2 and the Roll axis rotation accuracy of the lens 3, and effectively optimizing the gimbal imaging stability.

[0044] In addition, there is a stepped surface between the first connecting part 431 and the second connecting part 432. When installing the fastener 4, the stepped surface can be used for limiting, so that the installation depth of the fastener 4 in each fastener 2 is consistent, avoiding excessive installation error and simplifying the installation operation.

[0045] In some embodiments, there is an assembly gap between the first connecting portion 431 and the through hole 121, so that the first connecting portion 431 can adaptively float radially within the through hole 121. This reduces assembly difficulty.

[0046] like Figure 2 Figure 4 , Figure 6 and Figure 7 As shown, in order to facilitate the connection and fixation of the lens barrel 1 and the drive member 2 by the fixing member 4, the lens barrel 1 includes a lens barrel body 11 and a connecting part 12. The connecting part 12 is disposed on the inner wall of the lens barrel body 11 and extends to the inner side of the lens barrel body 11. The connecting part 12 is used to connect the fixing member 4.

[0047] Specifically, the fixing member 4 includes a first bolt 41, the connecting part 12 is provided with a through hole 121, the driving member 2 is provided with a first connecting hole 21, the flexible member 5 is a flexible washer, the first bolt 41 passes through the flexible washer and the through hole 121 in sequence and is placed in the first connecting hole 21, and is threadedly connected to the first connecting hole 21.

[0048] Furthermore, to make the connection between the lens barrel 1 and the driving component 2 more stable, a plurality of fixing members 4, flexible members 5, and connecting parts 12 are provided. The plurality of connecting parts 12 are evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, and the plurality of fixing members 4, flexible members 5, and connecting parts 12 are respectively arranged in a one-to-one correspondence. Specifically, in this embodiment, there are 5 fixing members 4, flexible members 5, and connecting parts 12, and the 5 connecting parts 12 are evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, and the 5 fixing members 4, 5 flexible members 5, and 5 connecting parts 12 are respectively arranged in a one-to-one correspondence. In other embodiments, the number of fixing members 4, flexible members 5, and connecting parts 12 may be 2, 3, 4, or 6, but this is not a limitation.

[0049] Correspondingly, there are multiple first connecting holes 21, each corresponding one-to-one with a fixing member 4. These multiple first connecting holes 21 are evenly distributed around the circumference of the drive member 2, with consistent spacing between them and the center of the drive member 2. Through simultaneous locking and installation with multiple sets of three-section fixing members 4 and flexible members 5, the locking pressure is evenly distributed along the circumference of the drive member 2, preventing unilateral deformation caused by single-point locking. The evenly distributed circumferential assembly structure, combined with independently set flexible members 5, can evenly absorb assembly errors and locking stress from various directions, further suppressing the skewness of the drive member 2. This, in conjunction with the rotating member 6 at the front end, eliminates over-constraint in the overall assembly. Simultaneously, the uniform force ensures the coaxiality of the drive member 2 and the lens 3, reducing the risk of lens 3 rotational eccentricity and improving the rotational stability of the Roll axis and imaging stability.

[0050] like Figure 2 and Figure 7 As shown, to make the connection between the lens barrel 1 and the drive component 2 more stable, one of the inner walls of the lens barrel 1 and the other of the side of the drive component 2 are provided with a protrusion 13 and a groove 22, respectively, with the protrusion 13 abutting against the inner wall of the groove 22. In this embodiment, the inner wall of the lens barrel 1 is provided with a protrusion 13, and the side of the drive component 2 is provided with a groove 22, with the protrusion 13 abutting against the inner wall of the groove 22. Specifically, to further make the connection between the drive component 2 and the lens barrel 1 more stable during operation, so that the drive component 2 does not jump when the internal shaft of the drive component 2 rotates, there are two protrusions 13 in the circumferential direction of the lens barrel 1, and correspondingly, there are two grooves 22 on the side of the drive component 2, with the two protrusions 13 and the two grooves 22 corresponding to each other. In other embodiments, there may be 3, 4, or 5 protrusions 13 and grooves 22 in the circumferential direction of the lens barrel 1, but this is not a limitation. In another embodiment, the inner wall of the lens barrel 1 may be provided with a groove, and the side of the drive member 2 may be provided with a protrusion. The protrusion abuts against the inner wall of the groove. The number of protrusions and grooves may be 1, 2, 3, 4 or 5, but is not limited thereto.

[0051] like Figure 4 , Figure 5 and Figure 7 As shown, to facilitate the connection between the drive component 2 and the lens 3, the drive component 2 is provided with a second connecting hole 23. The gimbal camera device also includes a connector 8. The lens 3 is provided with a lens connecting hole 31. The connector 8 passes through the second connecting hole 23 and the lens connecting hole 31 in sequence, threading the lens 3 to the drive component 2. Specifically, the connector 8 is a second bolt. The drive component 2 includes a fixed part and a rotating part, which are rotatably connected. To allow the lens 3 to rotate smoothly, the rotating part of the drive component 2 is connected to the lens 3.
