Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] In related technologies, to improve the rigidity of the camera module in a gimbal camera, a two-end support structure is typically used, with one end fixed by a motor and the other end mounted on a bracket via a support bearing. However, due to the accumulation of manufacturing tolerances and assembly errors in various components, the rotation axis of the camera module can easily become misaligned with the mounting hole of the support bearing. After forced assembly, the bearing will be subjected to radial stress, generating excessive and uneven rotational damping, which seriously affects the gimbal's stabilization performance and control accuracy.

[0022] To resolve the aforementioned technical issues, please refer to the following: Figure 1 and Figure 2 In a first aspect, embodiments of this application provide a support structure 10 applied to a gimbal camera 1000, the gimbal camera 1000 including a camera assembly 200, the camera assembly 200 being equipped with a support bearing 201.

[0023] In some embodiments, the support structure 10 includes a bracket 11, a connector 12, and an adhesive layer 13. The bracket 11 has a mounting hole 111. The connector 12 is connected to the support bearing 201, and the connector 12 is partially received within the mounting hole 111 of the bracket 11. A predetermined gap 14 is formed between the outer peripheral surface of the connector 12 and the inner wall of the mounting hole 111 of the bracket 11. The adhesive layer 13 fills the predetermined gap 14 and is connected to the bracket 11 and the connector 12 respectively, so as to fix the connector 12 to the bracket 11.

[0024] The principle of the support structure 10 in this embodiment is as follows: The gimbal camera 1000 includes a camera assembly 200 with a support bearing 201 and a support structure 10. The support structure 10 includes a bracket 11 and a connector 12, wherein the bracket 11 has a mounting hole 111. The connector 12 is connected to the support bearing 201 of the camera assembly 200. During assembly, a portion of the connector 12 is inserted into and housed inside the mounting hole 111 of the bracket 11. The outer peripheral surface of the connector 12 is not in close contact with the inner wall of the mounting hole 111 of the bracket 11, but forms a preset gap 14. The connector 12 is firmly fixed to the bracket 11 by an adhesive layer 13 that fills the preset gap 14 and is simultaneously connected to the surfaces of the bracket 11 and the connector 12, thereby completing the assembly of the entire support structure 10.

[0025] Understandably, this embodiment of the application solves the coaxiality deviation problem caused by the accumulation of manufacturing tolerances and assembly errors of the components by setting a preset gap 14 between the connector 12 and the bracket 11 and using adhesive fixation. The setting of the preset gap 14 allows the camera assembly 200 to float freely in the radial direction before final fixation, thereby naturally finding its balanced position coaxial with the drive motor 30 without being subjected to the forced stress of the bracket 11. After the adhesive layer 13 is cured, the camera assembly 200 is locked in this stress-free state, effectively avoiding the radial force applied to the support bearing 201 due to forced alignment in traditional rigid connections. This significantly reduces the rotational damping of the gimbal 100, ensures the smoothness and linearity of the rotation process, improves the accuracy and reliability of the stabilization control, and also relaxes the requirements for the processing accuracy of the components, reducing production costs and scrap rate.

[0026] For example, the adhesive layer 13 is formed by curing glue. Specifically, adhesive is injected or dispensed into the predetermined gap 14, and the adhesive layer 13 is formed after curing. The glue can be a light-curing glue or an acrylic glue, etc.

[0027] Please see together Figures 2 to 4In some embodiments, the connector 12 includes a bearing mounting portion 121 and a bracket mounting portion 122 disposed at both ends. The bearing mounting portion 121 is used to engage with the inner ring of the support bearing 201. The bracket mounting portion 122 is received in the mounting hole 111. A preset gap 14 is formed between the outer peripheral surface of the bracket mounting portion 122 and the inner wall of the mounting hole 111 of the bracket 11.

[0028] Understandably, the connector 12 includes a bearing mounting portion 121 and a bracket mounting portion 122 located at both ends. The bearing mounting portion 121 is used for a precise fit with the inner ring of the support bearing 201 on the camera assembly 200 to provide stable support. The bracket mounting portion 122 is the part that is received within the mounting hole 111 of the bracket 11 during assembly, and a pre-defined gap 14 is formed between its outer peripheral surface and the inner wall of the mounting hole 111. The pre-defined gap 14 is used to accommodate the cured adhesive layer 13. More easily understood, the bearing mounting portion 121 ensures a stable and reliable connection with the support bearing 201, ensuring the effective transmission of the support function. The bracket mounting portion 122, through a clearance fit and adhesion with the bracket 11, achieves flexible absorption of assembly errors and stress-free fixation.

[0029] Please refer to the following: Figures 2 to 5 In some embodiments, the bracket mounting portion 122 is provided with an outer flange 1221 in the circumferential direction. The outer flange 1221 is disposed opposite to the end face of the mounting hole 111. The adhesive layer 13 is respectively connected to the inner wall of the mounting hole 111, the circumferential surface of the bracket mounting portion 122 and the outer flange 1221.

[0030] Understandably, an outwardly protruding flange 1221 is provided circumferentially on the bracket mounting portion 122 of the connector 12. When the connector 12 is installed into the bracket 11, the end face of the flange 1221 is positioned opposite to the end face of the mounting hole 111 of the bracket 11. In this way, the adhesive layer 13 used for fixing not only fills the radial gap between the outer peripheral surface of the connector 12 and the inner wall of the mounting hole 111, but also partially bonds the flange 1221 to increase the adhesive contact area. The adhesive layer 13 is supported by the flange 1221, thereby improving the stability of the adhesive bond.

[0031] For example, the adhesive layer 13 may also be partially located below the end face of the mounting hole 111, forming an L-shaped adhesive interface, thereby greatly enhancing the strength of the connection and its resistance to shear and torsion. This structure makes the fixation more reliable, ensuring that the camera assembly 200 maintains a stable support state during long-term use, especially when subjected to vibration or impact loads, effectively improving durability and structural reliability.

[0032] Please refer to the following: Figure 3 and Figure 5In some embodiments, the outer peripheral surface of the outer flange 1221 includes interconnected arc segments 12211 and non-arc segments 12212. The bracket 11 is provided with a recess 112 that connects to the mounting hole 111. The recess 112 accommodates the outer flange 1221, and the inner wall of the recess 112 is adapted to the outer peripheral surface of the outer flange 1221.

[0033] Understandably, the outer peripheral surface of the outer flange 1221 of the connector 12 includes an arc segment 12211 and a non-arc segment 12212. Correspondingly, a recess 112 communicating with the mounting hole 111 is formed on the bracket 11. The inner wall shape of the recess 112 is adapted to the non-circular outer peripheral surface of the outer flange 1221 to accommodate the outer flange 1221 during assembly. In this embodiment, the non-circular contour fit between the outer flange 1221 and the recess 112 achieves circumferential positioning of the connector 12. On the one hand, it can play a role in preventing assembly errors; on the other hand, it can effectively prevent the connector 12 from rotating unexpectedly after the adhesive is injected but before curing is complete, or when subjected to torsional loads during subsequent use, thus ensuring the reliability of the assembly process and the performance consistency of the final product.

[0034] Please refer to the following: Figure 3 and Figure 5 In some embodiments, the bracket mounting portion 122 is provided with a positioning protrusion 1222, which extends radially outward from the circumferential surface of the bracket mounting portion 122. The bracket 11 is provided with a positioning through groove 113 that communicates with the mounting hole 111. The positioning through groove 113 accommodates the positioning protrusion 1222 and restricts the rotation of the connector 12.

[0035] Understandably, in this embodiment of the application, a radially outwardly extending positioning protrusion 1222 is provided on the circumferential surface of the bracket mounting portion 122 of the connector 12. Correspondingly, a positioning through groove 113 communicating with the mounting hole 111 is formed on the bracket 11. The size and position of the positioning through groove 113 match the size and position of the positioning protrusion 1222, and it is used to accommodate the positioning protrusion 1222 during assembly. Correspondingly, a positioning through groove 113 communicating with the mounting hole 111 is formed on the bracket 11. The size and position of the positioning through groove 113 match the size and position of the positioning protrusion 1222, and it is used to accommodate the positioning protrusion 1222 during assembly.

[0036] In this embodiment, the positioning protrusion 1222 cooperates with the positioning through groove 113 to achieve circumferential positioning of the connector 12, ensuring that the connector 12 is prevented from rotating during assembly and bonding curing.

[0037] Please review Figure 1 and Figure 2In some embodiments, the mounting hole 111 is provided with an outwardly extending notch 1111, the wall of the notch 1111 is an outwardly open slope, and the adhesive layer 13 is partially received in the notch 1111 and connected to the wall of the notch 1111.

[0038] Understandably, an outwardly extending notch 1111 is formed on the wall of the mounting hole 111, and the wall surface of the notch 1111 is set as an outwardly open slope. When the adhesive is filled, the adhesive will flow into and fill this notch 1111, and after curing, a mechanical locking structure that fits into the wall surface of the notch 1111 is formed inside the notch 1111.

[0039] To be more easily understood, the notch 1111 not only increases the bonding area, but the wedge-shaped or inverted structure formed by the cured adhesive within the notch 1111 provides a mechanical interlocking effect between the connector 12 and the bracket 11, improving the connection's resistance to pull-out and torsion. This makes the bonding fixation no longer solely dependent on the material's adhesion force, but rather adds a physical locking mechanism, thereby significantly improving the reliability and strength of the entire connection.

[0040] In some embodiments, there are two notches 1111, which are arranged opposite to each other and have opposite orientations. Each notch 1111 partially houses a corresponding adhesive layer 13.

[0041] Understandably, the two notches 1111 are arranged opposite each other on the mounting hole 111, and their outwardly opening bevels face opposite directions. During assembly, each notch 1111 is filled with adhesive to form its own mechanical locking structure. This embodiment employs a layout of two oppositely oriented notches 1111, so that the mechanical locking forces formed after curing create a pair of opposite-direction, torque-balanced locking actions in the circumferential direction. The symmetrical arrangement of the two notches 1111 in this embodiment helps to evenly distribute stress, avoiding stress concentration and unbalanced torque that might be caused by a single notch 1111, further enhancing the stability and balance of the overall structure.

[0042] In other embodiments, the outer peripheral surface of the bracket mounting portion 122 is a circular surface, and there are multiple adhesive layers 13, which are spaced apart around the center of the outer peripheral surface of the bracket mounting portion 122.

[0043] Understandably, the outer peripheral surface of the bracket mounting portion 122 of the connector 12 is a circular surface, and the adhesive layer 13 used for fixing does not continuously fill the entire annular gap, but exists in the form of multiple independent adhesive points. The independent adhesive layers 13 or adhesive points are arranged around the center of the outer peripheral surface of the bracket mounting portion 122 in a spaced-apart manner. The use of multiple spaced adhesive layers 13 in this embodiment can effectively reduce the amount of adhesive or glue used while ensuring sufficient fixing strength, thereby reducing costs and potentially shortening curing time.

[0044] Please refer to the following: Figure 1 , Figure 4 and Figure 6 In a second aspect, embodiments of this application provide a gimbal camera 1000, including a gimbal 100 and a camera assembly 200. The gimbal 100 includes an arm 20, a drive motor 30, and a support structure 10 as described in the above embodiments. The drive motor 30 is mounted on the arm 20, the support structure 10 is connected to the arm 20, and a connector 12 is spaced apart from the drive motor 30. The camera assembly 200 is connected to both the drive motor 30 and the connector 12, and is located between the drive motor 30 and the connector 12. The drive motor 30 is used to drive the camera assembly 200 to rotate relative to the arm 20.

[0045] Understandably, the gimbal camera 1000 includes a gimbal 100 and a camera assembly 200. The gimbal 100 includes an arm 20, a drive motor 30 mounted on the arm 20, and a support structure 10 connected to the arm 20, wherein the connector 12 of the support structure 10 is spaced apart from the drive motor 30. The camera assembly 200 is mounted between the drive motor 30 and the connector 12, with one end connected to the drive motor 30 and the other end connected to the connector 12. During operation, the drive motor 30 drives the camera assembly 200 to rotate relative to the arm 20. This embodiment applies the aforementioned support structure 10 to the gimbal camera 1000, solving problems such as bearing stress, increased rotational damping, and nonlinearity caused by accumulated assembly errors in the prior art gimbal camera 1000. The gimbal camera 1000 has the advantages of smoother rotation, better stabilization effect, and more precise control. At the same time, by relaxing the requirements for the precision of parts, the manufacturing cost of the entire product was reduced and the production yield was improved, ultimately resulting in a market competitive advantage that is both high-performing and economically efficient.

[0046] In some embodiments, the drive motor 30 includes a stator base 31, a stator assembly 32, and a rotor assembly 33, which are connected in a mating manner. The arm 20 is an L-shaped plastic component, the stator base 31 is an aluminum alloy structural component, the stator base 31 is embedded in the arm 20, and the stator assembly 32 is connected to the stator base 31 and mounted on the arm 20 via the stator base 31. The camera assembly 200 has a rotor mounting groove 202, and the rotor assembly 33 is partially housed within the rotor mounting groove 202. The rotor assembly 33 includes a rotor cover located at the outermost periphery, which is connected in a mating manner with the rotor mounting groove 202 and is bonded and fixed to the inner wall of the rotor mounting groove 202 with adhesive.

[0047] Thirdly, embodiments of this application provide a drone, including a fuselage and a gimbal camera 1000, with the gimbal camera 1000 mounted on the fuselage.

[0048] Please refer to the following: Figure 1 , Figure 6 and Figure 7 In a fourth aspect, embodiments of this application provide an assembly method for a gimbal camera 1000, the method comprising: S71. Provides a robotic arm 20, a drive motor 30, and a camera assembly 200, and pre-assembles the robotic arm 20, the drive motor 30, and the camera assembly 200, wherein the drive motor 30 is mounted on the robotic arm 20, and the camera assembly 200 is connected to the drive motor 30. S72. Provide a connector 12 to connect the connector 12 to the support bearing 201 of the camera assembly 200; S73. Provide a bracket 11, connect the bracket 11 to the arm 20 and the connector 12 respectively, and make the mounting hole 111 of the bracket 11 and the outer peripheral surface of the connector 12 form a preset gap 14. S74. Inject adhesive into the preset gap 14, and after curing, bond and fix the connector 12 and bracket 11.

[0049] In this step, adhesive can also be applied to the preset gap 14 and then cured to bond and fix the connector 12 and bracket 11.

[0050] In some embodiments, the mounting hole 111 has an outwardly extending notch 1111, the wall of the notch 1111 is an outwardly opening slope, the number of notches 1111 is two, the two notches 1111 are arranged opposite to each other, and the orientations of the two notches 1111 are opposite to each other. Step S74 includes: S741. Inject adhesive into notch 1111 and, after curing, bond and fix the connector 12 and bracket 11.

[0051] In this step, avoid letting the adhesive overflow onto the outer end face of the mounting hole when injecting the adhesive.

[0052] It is understood that the embodiments of this application adopt a layout of two opposite and oppositely oriented notches 1111, so that the mechanical locking force formed after curing forms a pair of locking actions with opposite directions and balanced torque in the circumferential direction.

[0053] In other embodiments, step S74 includes: S742. Inject adhesive at intervals along the extension path of the preset gap.

[0054] The preset gap can be set as an annular gap.

[0055] Understandably, the adhesive layer 13 formed by the cured adhesive does not continuously fill the entire annular gap, but exists in the form of multiple independent adhesive points. In this embodiment, the adhesive is injected at intervals along the extension path of a preset gap, which can effectively reduce the amount of adhesive or glue used while ensuring sufficient fixing strength, thereby reducing costs and potentially shortening the curing time.

[0056] In other embodiments, the connector 12 can be aligned with the bracket 11 first, and then connected together with the camera assembly 200 and the arm 20. Finally, adhesive or glue is injected into the preset gap 14 to cure and form the adhesive layer 13.

[0057] Understandably, the assembly method of the gimbal camera 1000 is as follows: First, the arm 20, drive motor 30, and camera assembly 200 are provided and pre-assembled, that is, the drive motor 30 is mounted on the arm 20, and one end of the camera assembly 200 is connected to the drive motor 30. Next, a connector 12 is provided and connected to the support bearing 201 at the other end of the camera assembly 200. Then, a bracket 11 is provided and connected to the arm 20, with its mounting hole 111 fitting over the connector 12, ensuring that a preset gap 14 is formed between the inner wall of the mounting hole 111 of the bracket 11 and the outer peripheral surface of the connector 12. Finally, adhesive is injected into the preset gap 14, and after the adhesive cures, the connector 12 and the bracket 11 are firmly bonded and fixed together.

[0058] To be more easily understood, this embodiment incorporates error compensation into the assembly process through a positioning-then-fixing assembly flow. Before injecting the adhesive, the entire camera assembly 200 can float freely at the end of the support structure 10, thereby naturally eliminating internal stress caused by tolerance accumulation. The final bonding step maintains the stress-free state of the support bearing 201 of the camera assembly 200, allowing the camera assembly 200 to be normally driven by the drive motor 30. The camera gimbal 100 assembly method of this embodiment is simple to operate, highly controllable, and can ensure low rotational damping and high coaxiality of the product from a process perspective, greatly improving assembly efficiency and product consistency and yield.
