[0002] The shooting gimbal is a supporting device used to install and fix shooting units such as mobile phones, cameras or camcorders. It can drive the shooting unit to rotate in one or more directions such as plane rotation, pitch and roll in space, making it convenient for users to shoot. The rotation of the shooting gimbal mainly depends on the internal motor. The shooting gimbal is generally mounted on a movable device, such as a drone, unmanned vehicle and other robots, and is widely used in navigation, path planning, target tracking and shooting functions.

[0003] At present, there needs to be a more secure fixing method between the shooting gimbal and the housing, which is generally fixed by bolts. The gimbal motor includes a rotor and a stator. The existing gimbal motor and the housing are usually fixed by bolting the housing and the inner ring of the rotor or the inner ring of the housing and the stator together. Usually, the bolts are removed from the outer surface of the housing, and the bolts are passed through the bolt holes of the housing and locked into the motor housing of the gimbal motor.

[0005] 2) When removing parts from the exterior surface, it is necessary to avoid the position of the bolt removal trajectory, so the specific structure of the casing must be adaptively adjusted, which affects the appearance of the shooting gimbal. Utility Model Content

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2As shown, this embodiment provides a shooting gimbal, including a stator assembly, a rotor body 200, a rotor housing 300 and a bolt 100; the stator assembly includes a first motor and a stator housing 400 fixedly connected to the first motor; the rotor body 200 is fixedly connected to the output end of the first motor, the first motor is used to drive the rotor body 200 to rotate around the first axis 202, and the rotor body 200 is penetrated by a plurality of rotor through holes 201; the rotor housing 300 includes a housing body plate 310, and the housing body plate 310 has The exterior surface and the working surface are opposite to each other, and the working surface is provided with a main body plate blind hole 311, and the number of the main body plate blind holes 311 and the rotor through holes 201 are the same. The stator housing 400 is penetrated by a screwdriver through hole 401, and each screwdriver through hole 401 can be connected with the corresponding main body plate blind hole 311 through a rotor through hole 201; the number of bolts 100 and the main body plate blind holes 311 is the same, and each bolt 100 passes through a screwdriver through hole 401 and a rotor through hole 201 in sequence, and is screwed to a main body plate blind hole 311.

[0029] The shooting gimbal can be connected to the corresponding main body plate blind hole 311 through a rotor through hole 201 by means of the screwdriver through hole 401, so that each bolt 100 passes through a rotor through hole 201 and is screwed to a main body plate blind hole 311, thereby realizing a stable connection between the rotor body 200 and the casing main body plate 310. The setting of the screwdriver through hole 401 realizes the avoidance of the disassembly and assembly trajectory of the bolt 100, and the design of the main body plate blind hole 311 being set on the working surface makes it possible to achieve a locked connection between the rotor body 200 and the rotor casing 300 without disassembling the components on the appearance surface, thereby optimizing the specific structure of the shooting gimbal, reducing the risk of rust damage of the bolt 100, and avoiding the situation where the screw rod of the bolt 100 extends into the stator casing 400. At the same time, it also improves the aesthetics of the shooting gimbal, which helps to achieve an integrated design of the appearance.

[0030] Specifically, the number of the bit through holes 401 and the blind holes 311 of the main body plate are the same and correspond one to one.

[0031] When assembling the bolt 100, the rotor body 200 needs to be rotated to the state where the rotor through hole 201 and the screwdriver through hole 401 are facing each other, and then the housing main body plate 310 is correspondingly buckled on the rotor body 200 to achieve the state where the screwdriver through hole 401, the rotor through hole 201 and the main body plate blind hole 311 are connected in sequence, and then the bolt 100 is screwed in along the above path. When removing the bolt 100, the rotor body 200 needs to be rotated to the state where the rotor through hole 201 and the screwdriver through hole 401 are facing each other, and then the bolt 100 is loosened and removed from the screwdriver through hole 401, and finally the rotor housing 300 is removed.

[0032] In this embodiment, the rotor housing includes a motor base 330, and the appearance surface is fixedly connected to the motor base 330 through a connecting plate 320; a second motor 500 is also fixedly connected to the motor base 330, and the output end of the second motor 500 is connected to a shooting unit 600, and the second motor 500 is used to drive the shooting unit 600 to rotate around the second axis 501, and the shooting unit 600 is arranged at the intersection of the first axis 202 and the second axis 501; the output end of the second motor 500 passes through the motor base 330.

[0033] The design of setting the shooting unit 600 at the intersection of the first axis 202 and the second axis 501 limits the layout position of the shooting unit 600, ensuring that the driving action of the first motor and the second motor 500 can only drive the shooting unit 600 to rotate, and cannot cause the position of the shooting unit 600 to shift, thereby improving the shooting effect of the shooting unit 600, enhancing the user experience, and increasing the market competitiveness of the shooting gimbal. At the same time, the design of the output end of the second motor 500 passing through the motor seat 330 realizes the optimized layout of the second motor 500 on the motor seat 330, plays the purpose of limiting the output end of the second motor 500, reduces the risk of the second motor 500 accidentally detaching from the motor seat 330, and reduces the space occupied by the shooting gimbal.

[0034] Exemplarily, the length direction of the connecting plate 320 is perpendicular to the housing main plate 310, one end of the connecting plate 320 is fixedly connected to the housing main plate 310, and the other end is fixedly connected to the motor seat 330. The above design limits the specific structure of the connecting plate 320, simplifies the structure of the connecting plate 320, reduces the production cost of the rotor housing 300, and reduces the space occupied by the shooting gimbal.

[0035] In this embodiment, the screw rod of the bolt 100 passes through the rotor through hole 201 and the main body plate blind hole 311, and the rotor body 200 is sandwiched between the screw head of the bolt 100 and the housing main body plate 310. The design of clamping the rotor body 200 by the screw head of the bolt 100 and the housing main body plate 310 allows the bolt 100 to press the rotor body 200 and lock it to the housing main body plate 310, effectively avoiding the situation where the rotor body 200 is offset. The above design improves the connection stability between the rotor body 200 and the housing main body plate 310, ensuring the long-term stable operation of the shooting gimbal.

[0036] Exemplarily, three rotor through holes 201 are provided, and the three rotor through holes 201 are evenly distributed circumferentially around the axis of the rotor body 200. The circumferentially evenly distributed position limitation realizes the layout of the screw connection position of the bolt 100, ensures the connection stability between the rotor body 200 and the housing body plate 310, reduces the risk of the housing body plate 310 being separated from the rotor body 200 due to accident, ensures the working stability of the shooting gimbal, and ensures the smooth shooting of the shooting unit 600.

[0037] In this embodiment, the depth direction of the blind hole 311 of the main plate is parallel to the first axis 202. The above design simplifies the specific structure of the shooting gimbal and reduces the difficulty of disassembling and assembling the bolt 100. The above definition also helps to improve the stress condition of the bolt 100 and reduce the risk of the bolt 100 being loosened due to accident.

[0038] Exemplarily, the stator housing 400 encloses a motor slot and a rotor slot, the main body of the first motor is arranged in the motor slot, the rotor body 200 is arranged in the rotor slot, the screwdriver through hole 401 connects the motor slot and the rotor slot, and the output end portion of the first motor extends into the rotor slot.

[0039] The structural layout of the motor slot and the rotor slot defines the installation positions of the first motor and the rotor body 200, and also defines the layout position of the bit through hole 401. The above definition optimizes the specific structure of the stator assembly, plans the alignment method of the bit through hole 401 and the rotor through hole 201, and ensures that the bit through hole 401 and the rotor through hole 201 can be smoothly connected, thereby reducing the difficulty of disassembly and assembly of the bolt 100, reducing the production cost of the stator housing 400, and reducing the space occupied by the shooting gimbal.

[0040] In this embodiment, the length direction of the screwdriver through hole 401, the length direction of the rotor through hole 201 and the length direction of the main plate blind hole 311 are all the same. The above design reduces the difficulty of processing the screwdriver through hole 401, the rotor through hole 201 and the main plate blind hole 311, reduces the production cost of the shooting gimbal, thereby further reducing the difficulty of disassembling and assembling the bolt 100 and improving the efficiency of disassembling and assembling.

[0041] Exemplarily, the axis of the output end of the first motor coincides with the axis of the rotor body 200. The above definition realizes the coaxial rotation of the output end of the first motor and the rotor body 200, ensures the smooth rotation of the rotor body 200, prolongs the service life of the rotor body 200, and further reduces the space occupied by the shooting gimbal.

[0042] In this embodiment, the first axis 202 is perpendicular to the second axis 501. The above definition reduces the difficulty of rotating the shooting unit 600, simplifies the method of adjusting the angle of the shooting unit 600, optimizes the specific structure of the shooting gimbal, and helps to improve the user experience.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
