Description
Technical Field
[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a gimbal rotation shaft and motor structure. Background Technology
[0002] A gimbal is a support device for mounting and fixing mobile phones, cameras, and camcorders. There are two types: fixed gimbals and motorized gimbals.
[0003] In related technologies, electric gimbals are typically three-axis gimbals. The gimbal rotation axis of a three-axis gimbal usually includes a rotor body and a gimbal frame. The gimbal frame typically has positioning posts, and the rotor body and gimbal frame are usually assembled and positioned using these positioning posts. The gimbal frame is usually injection molded, while the positioning posts typically have a diameter of only 1mm-1.2mm. During assembly, due to their small size and low strength, the positioning posts are difficult to position and align, and are easily damaged, resulting in low assembly efficiency.

[0036] Reference Figure 1 and Figure 2 As shown, this embodiment provides a gimbal rotation shaft, which includes a rotor body and a gimbal frame 200.
[0037] Specifically, the rotor body includes a rotor shaft and a mounting base 100 connected to the rotor shaft; the gimbal frame 200 includes a base 210 and a gimbal arm 220 mounted on the base 210. One of the mounting base 100 and the base 210 is provided with a limiting block 211, and the other with a limiting channel 110. The limiting block 211 passes through the limiting channel 110, and a gap is formed between the limiting block 211 and the limiting channel 110. One of the mounting base 100 and the base 210 is provided with a positioning post 212, and the other with a positioning channel 120. The positioning post 212 passes through the positioning channel 120, and the positioning post 212 is in contact with the inner wall of the positioning channel 120.
[0038] In this embodiment, when assembling the gimbal rotation shaft, the limiting block 211 is first inserted into the limiting channel 110, as a gap exists between the limiting block 211 and the limiting channel 110. Then, the rotor body or the gimbal frame 200 is shaken to allow the positioning post 212 to pass through the positioning channel 120, effectively preventing damage to the positioning post 212 and achieving the positioning assembly of the rotor body and the gimbal frame 200. This method of first using the limiting block 211 for coarse positioning and then using the positioning post 212 for fine positioning reduces adjustments during assembly and significantly improves assembly efficiency. Furthermore, because the positioning post 212 fits snugly against the inner wall of the positioning channel 120, the assembly accuracy of the rotor body and the gimbal frame 200 is effectively guaranteed.
[0039] For example, the mounting base 100 can be made of metal.
[0040] For example, the base 210 can be manufactured by injection molding. The base 210 and the gimbal arm 220 can be an integral structure, that is, the gimbal frame 200 can be manufactured by injection molding in one step.
[0041] For example, multiple limit blocks 211 are spaced around the rotor shaft, and multiple limit channels 110 are provided and are set one-to-one with the limit blocks 211. By using the limit blocks 211 for coarse positioning, the positioning post 212 and the positioning channel 120 can be restricted to a smaller relative position adjustment range, which can further improve assembly efficiency and more effectively prevent damage to the positioning post 212.
[0042] For example, the limiting blocks 211 are provided at intervals of 2 to 8, such as 3, 4 or 5, around the rotor shaft.
[0043] For example, multiple positioning posts 212 are spaced around the rotor shaft, and multiple positioning channels 120 are provided and are arranged one-to-one with the positioning posts 212, so as to disperse the force on the positioning posts 212 and more effectively prevent damage to the positioning posts 212.
[0044] For example, the positioning pins 212 are spaced 2 to 8, such as 3, 4 or 5, around the rotor shaft.
[0045] In one feasible implementation, such as Figure 2 As shown, the cross-sectional outer contour area of the limiting block 211 is greater than or equal to the cross-sectional outer contour area of the positioning post 212. In this embodiment, the limiting block 211 has a larger size, that is, the structural strength of the limiting block 211 is high, which effectively prevents the limiting block 211 from being damaged during the adjustment process of the positioning post 212 for precise positioning; and the positioning post 212 has a smaller size, which has higher injection molding precision, effectively ensuring the assembly precision of the rotor body and the gimbal frame 200.
[0046] For example, the diameter of the positioning post 212 is 1mm-1.2mm, such as 1.1mm or 1.15mm.
[0047] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the limiting block 211 and the positioning post 212 are both disposed on the base 210; the limiting channel 110 and the positioning channel 120 are both disposed on the mounting base 100, facilitating the molding and manufacturing of the mounting base 100 and the base 210. In this embodiment, on the side of the mounting base 100 opposite to the base 210, the positions of the limiting block 211 and the positioning post 212 can be observed simultaneously through the limiting channel 110 and the positioning channel 120, which facilitates the positioning and assembly of the rotor body and the gimbal frame 200.
[0048] In one feasible implementation, the limiting block 211 and the positioning post 212 are both provided on the mounting base 100; the limiting channel 110 and the positioning channel 120 are both provided on the base 210, which facilitates the molding and manufacturing of the mounting base 100 and the base 210.
[0049] In one feasible implementation, the limiting block 211 and the positioning channel 120 are both disposed on the mounting base 100; the limiting channel 110 and the positioning post 212 are both disposed on the base 210. In this embodiment, the position of the positioning post 212 can be observed through the positioning channel 120 on the side of the mounting base 100 away from the base 210, which facilitates the positioning post 212 to pass through the positioning channel 120.
[0050] In one feasible implementation, both the limiting block 211 and the positioning channel 120 are disposed on the base 210; both the limiting channel 110 and the positioning post 212 are disposed on the mounting base 100. In this embodiment, the position of the limiting block 211 can be observed through the limiting channel 110 on the side of the mounting base 100 opposite to the base 210, facilitating the insertion of the limiting block 211 through the limiting channel 110. Of course, the limiting block 211 and the positioning post 212 can also both be disposed on the mounting base 100; and both the limiting channel 110 and the positioning channel 120 can be disposed on the base 210.
[0051] In one feasible implementation, such as Figure 2 As shown, the base 210 is provided with a groove 2101, and the limiting block 211 and the positioning post 212 are both provided in the groove 2101 to protect the limiting block 211 and the positioning post 212 and effectively prevent the limiting block 211 and the positioning post 212 from being damaged due to collision with other components.
[0052] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the periphery of the limiting block 211 fits against the side wall of the groove 2101, and the limiting channel 110 is set as an open groove to facilitate the limiting block 211 passing through the limiting channel 110, and to facilitate the forming of the mounting base 100 and the base 210.
[0053] For example, the limiting block 211 includes an arc-shaped sidewall 2111, and the limiting channel 110 is configured as an arc-shaped opening groove. The arc-shaped sidewall 2111 is located in the arc-shaped opening groove. The limiting block 211 moves more flexibly relative to the limiting channel 110, and ensures that the position adjustment of the limiting block 211 relative to the limiting channel 110 is within a small range, effectively reducing the adjustment during the assembly process.
[0054] For example, the limiting block 211 is provided with a limiting groove 2112. During the injection molding process of the base 210, the plastic material can flow and fill evenly, reducing defects caused by air trapping, improving the cooling process of the base 210, improving the quality and efficiency of injection molding, and effectively preventing the base 210 from cracking. The limiting block 211 can also effectively prevent the base 210 from deforming during injection molding, ensuring the molding accuracy of the base 210. Optionally, the limiting groove 2112 can extend to the side wall of the groove 2101. Optionally, the limiting block 211 can be U-shaped, with the ends of the two arms of the U-shaped limiting block 211 fitting against the side wall of the groove 2101.
[0055] Of course, the shape of the limiting block 211 can also be an elliptical ring or a circular ring, and the corresponding shape of the limiting channel 110 can be a waist-shaped hole, an elliptical hole or a circular hole.
[0056] In one feasible implementation, such as Figure 2 As shown, multiple reinforcing ribs 213 can be spaced apart circumferentially around the rotor shaft within the groove 2101, and positioning posts 212 are provided on at least some of the reinforcing ribs 213. It is understood that the reinforcing ribs 213 are connected to the sidewalls and bottom of the groove 2101. In this embodiment, the design of the reinforcing ribs 213 effectively prevents deformation of the base 210 during injection molding, ensuring the molding accuracy of the base 210. Furthermore, by setting the reinforcing ribs 213, the axial length of the positioning posts 212 can be reduced, thereby increasing the structural strength of the positioning posts 212 and further preventing damage to the positioning posts 212 during the positioning and assembly process of the rotor body and the gimbal frame 200.
[0057] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the mounting base 100 and the base 210 can be connected by bolts.
[0058] For example, the mounting base 100 is provided with a plurality of mounting holes 130 spaced around the rotor shaft in the circumferential direction, and the base 210 is provided with connecting posts 214 corresponding to the mounting holes 130 one by one. Nuts (not shown) can be pre-embedded in the connecting posts 214, and bolts (not shown) are threaded through the mounting holes 130 one by one and threadedly connected to the nuts, so as to facilitate the assembly between the mounting base 100 and the base 210.
[0059] For example, the mounting holes 130 are provided with 3 to 8 holes spaced around the rotor shaft, such as 4, 5 or 6.
[0060] For example, the connecting column 214 may intersect with the reinforcing rib 213, and the positioning column 212 may be located at the intersection of the connecting column 214 and the reinforcing rib 213, effectively ensuring the structural strength and forming accuracy of the positioning column 212. It is understood that a portion of the axial projection of the connecting column 214 is located on the reinforcing rib 213, and another portion is located on the connecting column 214.
[0061] For example, an arc-shaped plate 215 is provided within the groove 2101. The arc-shaped plate 215 may intersect with at least a portion of the reinforcing ribs 213 on the side away from the sidewall of the groove 2101, or with at least a portion of the connecting posts 214, or with both the side of at least a portion of the reinforcing ribs 213 on the side away from the sidewall of the groove 2101 and at least a portion of the connecting posts 214, to ensure the forming quality of the base 210. Multiple arc-shaped plates 215 may be provided at circumferential intervals around the rotor shaft, for example, two to three.
[0062] This embodiment also provides a motor structure, which includes a motor housing, a stator, and the aforementioned gimbal rotation shaft. Specifically, the stator is disposed inside the motor housing, the rotor shaft of the rotor body of the gimbal rotation shaft is rotatably disposed inside the motor housing, and the mounting base 100 of the rotor body is located outside the motor housing. In this embodiment, the motor structure, through the arrangement of the gimbal rotation shaft, facilitates assembly and achieves high assembly efficiency.
[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
