The outer ring of a bearing is fixed in the rotating hole, and the rotating shaft protrusion is inserted into the inner ring of the bearing, thereby realizing the rotating connection between the adapter bracket and the shooting device.
[0005] During the implementation of the embodiments of this application, the inventors discovered that, using the above-described method, the shooting device is prone to move relative to the adapter bracket in the axial direction of the bearing, affecting the shooting quality. Utility Model Content
[0006] The main technical problem solved by the embodiments of this application is to provide a gimbal and a drone that can limit the movement of the shooting device relative to the adapter bracket along a first direction.
[0007] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a gimbal, including an adapter bracket, a shooting device, a bearing, and fasteners. The adapter bracket includes a fixed arm and a first connecting arm, one end of which is connected to the first connecting arm. The shooting device is provided with a receiving groove and a rotating hole, the rotating hole communicating with the receiving groove. The outer ring of the bearing is fixed to the rotating hole.

[0009] In some embodiments, the imaging device has a limiting groove on the surface facing the mounting member, and the mounting member has a limiting protrusion, the limiting protrusion being at least partially received in the limiting groove.
[0010] In some embodiments, the gimbal includes a screw connector, the mounting member has a through hole, the screw connector passes through the through hole, and the screw connector is screwed to the connecting body.
[0011] In some embodiments, the fastener includes a threaded portion and an abutment portion, the abutment portion being connected to one end of the threaded portion, the threaded portion passing through an inner ring and being threaded and fixed to the mounting member, and the abutment portion abutting against one end of the inner ring away from the mounting member.
[0012] In some embodiments, the abutment portion is provided with at least two clearance notches, which are spaced apart along the circumferential direction of the abutment portion, and the clearance notches are configured to engage with a locking tool.
[0013] In some embodiments, in the first direction, the size of the abutment portion is smaller than the size of the mounting member.
[0014] In some embodiments, the outer ring of the bearing is bonded and fixed to the imaging device.
[0015] In some embodiments, the adapter bracket includes a second connecting arm, which is connected to the end of the fixed arm away from the first connecting arm. The shooting device is rotatably connected to the end of the second connecting arm away from the fixed arm, and the shooting device is located between the first connecting arm and the second connecting arm.
[0016] To solve the above-mentioned technical problems, another technical solution adopted in this application embodiment is: to provide a drone, including a drone body and the above-mentioned gimbal, with a fixed arm fixed to the drone body.
[0017] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, the outer ring is fixed to the rotating hole, and a fastener is set, which abuts against one end of the inner ring and the first connecting arm abuts against the other end of the inner ring, thereby restricting the movement of the shooting device relative to the adapter bracket in the first direction, which helps to reduce the shaking of the shooting device and thus improve the shooting quality of the shooting device.

[0023] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0024] Please see Figure 1 and Figure 2 The gimbal 100 includes an adapter bracket 1, a shooting device 2, a bearing 3, and a fastener 4. The bearing 3 is disposed on the shooting device 2. The fastener 4 passes through the inner ring 31 of the bearing 3 and is screwed onto the adapter bracket 1 so that the shooting device 2 can rotate relative to the adapter bracket 1 around the axis of the bearing 3. The adapter bracket 1 is used to fix to the drone body 200, thereby realizing the connection between the shooting device 2 and the drone body 200.
[0025] For the adapter bracket 1 mentioned above, please refer to... Figure 2 and Figure 3 The adapter bracket 1 includes a fixed arm 11 and a first connecting arm 12. One end of the fixed arm 11 is connected to one end of the first connecting arm 12. The fastener 4 passes through the inner ring 31 of the bearing 3 and is screwed to the end of the first connecting arm 12 away from the fixed arm 11. The fixed arm 11 is used to fix the UAV body 200.
[0026] For the aforementioned shooting device 2, please refer to... Figure 2 and Figure 3 The shooting device 2 is provided with a receiving groove 21 and a rotating hole 22. The receiving groove 21 is used to accommodate the lens module (not shown) and control circuit module (not shown) of the shooting device 2. The rotating hole 22 is connected to the receiving groove 21. The outer ring 32 of the bearing 3 is disposed in the rotating hole 22 and is fixed to the inner wall of the rotating hole 22. The fastener 4 passes through the inner ring 31 of the bearing 3 and is screwed to the first connecting arm 12 along the first direction X. The fastener 4 abuts against one end of the inner ring 31, and the first connecting arm 12 abuts against the other end of the inner ring 31, thereby restricting the movement of the shooting device 2 relative to the first connecting arm 12 along the first direction X, wherein the first direction X is parallel to the axis of the bearing 3. In this embodiment, the outer ring 32 is fixed to the rotating hole 22. By setting the fastener 4, the fastener 4 abuts against one end of the inner ring 31, and the first connecting arm 12 abuts against the other end of the inner ring 31, thereby restricting the movement of the shooting device 2 relative to the adapter bracket 1 in the first direction X, which helps to reduce the shaking of the shooting device 2 and thus improve the shooting quality of the shooting device 2.
[0027] In some embodiments, the outer ring 32 of the bearing 3 is bonded and fixed to the inner wall of the rotating hole 22. Bonding is used to fix the outer ring 32 to the inner wall of the rotating hole 22, which is simple and convenient.
[0028] In some embodiments, the first connecting arm 12 includes a connecting body 121 and a mounting member 122. One end of the connecting body 121 is connected to one end of the fixing arm 11. The other end of the connecting body 121 is provided with a mounting groove 1211. The mounting member 122 is disposed in the mounting groove 1211. The fastener 4 passes through the inner ring 31 from the receiving groove 21, and the portion of the fastener 4 protruding from the inner ring 31 is screwed and fixed to the mounting member 122. In the first direction X, the mounting member 122 abuts against the end of the inner ring 31 that is away from the receiving groove 21. It is worth noting that since the fastener 4 needs to be screwed to the mounting part 122, if the thickness of the mounting part 122 (i.e., the size of the mounting part 122 in the first direction X) is too small, the screwing length between the fastener 4 and the mounting part 122 will be too small, which will lead to an unstable connection between the fastener 4 and the mounting part 122, making it difficult for the fastener 4 to restrict the movement of the shooting device 2 along the first direction X. Therefore, it is necessary to ensure that the mounting part 122 has sufficient thickness. In this case, if the mounting part 122 is placed in the receiving groove, and the fastener 4 passes through the inner ring 31 from the mounting groove 1211 of the connecting body 121 and is screwed to the mounting part 122 in the receiving groove, it is easy for the mounting part 122 to occupy too much space in the receiving groove 21, affecting the distribution of the internal components of the shooting device 2 (such as the lens module and the control circuit module). In this embodiment, by setting an mounting groove 1211 in the connecting body 121, setting the mounting component 122 in the mounting groove 1211, and screwing the fastener 4 through the inner ring 31 from the receiving groove 21 to the mounting component 122, it is beneficial to reduce the space occupied by other components (other components refer to components other than the shooting device 2, such as the fastener 4, the mounting component 122, etc.) in the receiving groove 21, and facilitate the distribution and assembly of components such as the lens module and control circuit module of the shooting device 2 in the receiving groove 21.
[0029] In some embodiments, please refer to Figure 2 and Figure 3 The fastener 4 includes a screwed part 41 and an abutment part 42. One end of the abutment part 42 is connected to one end of the screwed part 41. The screwed part 41 passes through the inner ring 31 of the bearing 3 and is screwed onto the mounting member 122. The abutment part 42 abuts against the end of the inner ring 31 that is away from the mounting member 122, thereby restricting the movement of the shooting device 2 along the first direction X.
[0030] In some embodiments, in the first direction X, the size of the abutment portion 42 is smaller than the size of the mounting member 122, which helps to reduce the space occupied by the abutment portion 42 in the receiving groove 21, thereby facilitating the distribution of components such as the lens module and control circuit module of the shooting device 2 in the receiving groove 21.
[0031] In some embodiments, the size of the abutment portion 42 in the first direction X is 1mm to 2mm.
[0032] In some embodiments, the thickness of the mounting member 122 in the first direction X is 3mm to 8mm.
[0033] In some embodiments, please refer to Figure 2 and Figure 3 The mounting part 122 is provided with a first screw hole 1222, which penetrates the mounting part 122 along the first direction X. The end of the screw connection part 41 away from the abutment part 42 is provided with an external thread 411. The screw connection part 41 is screwed into the first screw hole 1222 through the external thread 411, thereby realizing the screw connection and fixation between the fastener 4 and the mounting part 122.
[0034] In some embodiments, please refer to Figure 2 and Figure 3 A limiting groove 23 is provided on the surface of the imaging device 2 facing the mounting member 122. Viewed along the first direction X, the limiting groove 23 is C-shaped and surrounds the periphery of the rotating hole 22. A limiting protrusion 1221 is provided at one end of the mounting member 122 facing the imaging device 2. The limiting protrusion 1221 is at least partially received in the limiting groove 23, thereby limiting the range of rotation angle of the imaging device 2 relative to the adapter bracket 1.
[0035] In some embodiments, please refer to Figure 2 and Figure 3 The end of the connecting body 121 facing the shooting device 2 is provided with a relief groove 1213. The relief groove 1213 is connected to the mounting groove 1211. The relief groove 1213 is used to avoid the fastener 4 and the limiting protrusion 1221, so that the fastener 4 can pass through the relief groove 1213 and be screwed into the mounting part 122 in the mounting groove 1211, and the limiting protrusion 1221 can pass through the relief groove 1213 and be inserted into the limiting groove 23.
[0036] In some embodiments, the gimbal 100 further includes a screw connector 5, and the mounting member 122 is provided with a through hole 1223. The through hole 1223 passes through the mounting member 122 along the first direction X. After the screw connector 5 passes through the through hole 1223, it is screwed to the connecting body 121, thereby fixing the mounting member 122 and the connecting body 121.
[0037] Furthermore, the connecting body 121 is also provided with a second screw hole 1212, which is located at the bottom of the mounting groove 1211. The screw connector 5 passes through the through hole 1223 and is screwed into the second screw hole 1212, thereby achieving the fixation between the mounting component 122 and the connecting body 121.
[0038] In some embodiments, please refer to Figure 2and Figure 3 The mounting component 122 has multiple screw connectors 5, and the mounting member 122 has multiple through holes 1223 spaced apart from each other. The bottom of the mounting groove 1211 has multiple second screw holes 1212. A screw connector 5 passes through a through hole 1223 and is screwed into a second screw hole 1212. By providing multiple screw connectors 5, the stability of the fixation between the mounting member 122 and the connecting body 121 is improved.
[0039] In some embodiments, please refer to Figure 2 and Figure 3 The abutment portion 42 is provided with at least two clearance notches 421, which are spaced apart along the circumferential direction of the abutment portion 42. The clearance notches 421 are configured to allow the fastening tool to be inserted and engaged, so as to facilitate the use of the fastening tool to lock the fastener 4 to the mounting part 122.
[0040] In some embodiments, please refer to Figure 2 and Figure 3 The adapter bracket 1 also includes a second connecting arm 13. One end of the second connecting arm 13 is connected to the end of the fixed arm 11 away from the first connecting arm 12. The shooting device 2 is connected to the end of the second connecting arm 13 away from the fixed arm 11, and the shooting device 2 can rotate relative to the second connecting arm 13. In this embodiment, by setting the second connecting arm 13, the shooting device 2 is rotatably connected to the second connecting arm 13, which helps to improve the stability of the connection between the adapter bracket 1 and the shooting device 2 and reduces the risk of the shooting device 2 detaching from the adapter bracket 1.
[0041] In some embodiments, the first connecting arm 12 is substantially perpendicular to the fixed arm 11, and the second connecting arm 13 is substantially perpendicular to the fixed arm 11, so that the first connecting arm 12, the fixed arm 11 and the second connecting arm 13 substantially form a "U" shape, and the shooting device 2 is located between the first connecting arm 12 and the second connecting arm 13, thereby facilitating the shooting device 2 to be rotatably connected to the first connecting arm 12 and the second connecting arm 13 respectively.
[0042] In some embodiments, the second connecting arm 13 is provided with a motor slot 131, which is used to accommodate a motor (not shown). The output shaft of the motor is used to connect to the shooting device 2 so that the motor can drive the shooting device 2 to rotate.
[0043] In this embodiment, the outer ring 32 is fixed to the rotating hole 22. By setting a fastener 4, the fastener 4 abuts against one end of the inner ring 31 and the first connecting arm 12 abuts against the other end of the inner ring 31, thereby restricting the movement of the shooting device 2 relative to the adapter bracket 1 in the first direction X, which helps to reduce the shaking of the shooting device 2 and thus improve the shooting quality of the shooting device 2.
[0044] This application also provides 1000 embodiments of unmanned aerial vehicles (UAVs), please refer to [link / reference]. Figure 4 The drone 1000 includes the drone body 200 and the gimbal 100 mentioned above. The fixed arm 11 of the gimbal 100 is fixed to the drone body 200 so that the drone body 200 can carry the gimbal 100 for aerial operations. For the specific structure and function of the gimbal 100, please refer to the above embodiments, which will not be repeated here.
