DETAILED DESCRIPTION

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5 As shown, a motor fixing device installed on a drone frame includes: a motor body 13, a protective mechanism, and a shaft extension mechanism. An outer frame 9 is provided at the middle of the outer side of the motor body 13, a bottom shaft opening 2 is provided at the middle of the bottom end of the outer frame 9, and a screw shaft 8 is provided at the bottom end of the bottom shaft opening 2.

[0026] The protective mechanism is used to protect the outer casing of the motor body 13;

[0027] The shaft-increasing mechanism is used to increase the diameter of the pivot portion of the motor body 13.

[0028] For the remaining components, when installing the motor body 13, first snap the C-shaped plate 12 onto the outer corner of the motor body, then symmetrically place the L-shaped plate 11 inside the inner frame 1, insert the T-shaped plate 10, and use the magnetic attraction of the T-shaped plate 10 to attract the motor body 13, thus completing the fixing of the protective mechanism. The outer frame 9 supports the overall structure. When installing the shaft extension mechanism, connect the screw shaft 8 to the outer rotating bushing 3 via threads, rotate the outer rotating bushing 3 to adjust the position of the outer expansion shaft 7, and insert the insertion shaft 6 into the insertion hole 4 of the outer expansion shaft 7, so that the rectangular plane of the inner block 5 matches the rectangular opening at the bottom of the outer expansion shaft 7 to prevent the insertion shaft 6 from rotating. At this time, the diameter of the outer expansion shaft 7 is larger than the diameter of the pivot part of the motor body 13. When installed on the drone frame, the increased shaft diameter makes the connection more stable and reduces shaking. The multi-layered structure of the protective mechanism buffers external impacts and protects the outer shell of the motor body 13.

[0029] like Figures 1-5 As shown, a motor fixing device installed on a drone frame includes a protective mechanism comprising a T-shaped plate 10, an L-shaped clamping plate 11, a C-shaped plate 12, and an inner frame 1. C-shaped plates 12 are positioned at the four corners of the inner side of the outer frame 9. L-shaped clamping plates 11 are clamped to the inner side of the C-shaped plates 12. The inner frame 1 is positioned at the middle of the outer side of the L-shaped clamping plates 11. The L-shaped clamping plates 11 are symmetrically placed inside the inner frame 1. A T-shaped plate 10 is inserted into the middle of the symmetrically placed L-shaped clamping plate 11 structure.

[0030] The axis increasing mechanism comprises an outer rotating sleeve 3, an outer expanding shaft 7, a plug hole 4, a plug shaft 6, and an inner embedded block 5, the bottom end of the screw shaft 8 is provided with the outer rotating sleeve 3, the bottom end of the outer rotating sleeve 3 is provided with the outer expanding shaft 7, the middle of the bottom end of the outer expanding shaft 7 is provided with the plug hole 4, the inner side of the plug hole 4 is provided with the plug shaft 6, the bottom end of the plug shaft 6 is provided with the inner embedded block 5, the two sides of the inner embedded block 5 are rectangular planes, and the bottom opening of the outer expanding shaft 7 is a rectangular opening.

[0031] The rest, when the motor fixing device is installed on the unmanned aerial vehicle frame, the C-shaped plate 12, the L-shaped clamping plate 11 and the T-shaped plate 10 of the protection mechanism cooperate to fix the motor body 13, and the magnetic attraction piece of the T-shaped plate 10 ensures the stability of the motor body 13. The outer frame 9 cooperates with the inner frame 1, and the width formed after the C-shaped plate 12 is clamped is adapted to the distance between the two, thereby enhancing the protection capability. In the axis increasing mechanism, the outer rotating sleeve 3 is connected with the screw shaft 8 through threads, and rotating the outer rotating sleeve 3 makes the outer expanding shaft 7 reach the specified position. The plug shaft 6 is inserted into the plug hole 4, and the inner embedded block 5 fixes the plug shaft 6,

[0032] In addition, the outer expanding shaft 7 is connected more closely with the frame because the diameter is greater than the motor pivot part, and in the process of use, if an external object hits, the protection mechanism can buffer the impact and protect the motor body 13; the axis increasing mechanism ensures the stability of the shaft connection, makes the power transmission efficient, and meets the operation requirements of the unmanned aerial vehicle.

[0033] Working principle: when the motor fixing device installed on the unmanned aerial vehicle frame is used, first, when the motor body 13 is installed, the outer frame 9 serves as a basic support structure. In the protection mechanism, the C-shaped plate 12 is clamped on the outside corner of the motor body, the L-shaped clamping plate 11 cooperates with the C-shaped plate 12, the symmetrically placed L-shaped clamping plates 11 are fixed by the T-shaped plate 10, the magnetic attraction piece of the T-shaped plate 10 attracts the motor body 13, and the fixing effect is strengthened;

[0034] The inner frame 1 cooperates with the inner side of the outer frame 9 at a distance adapted to the width formed after the C-shaped plate 12 is clamped, thereby constructing a multi-layer protection system. When the axis increasing mechanism operates, the screw shaft 8 is connected with the outer rotating sleeve 3 through threads, and rotating the outer rotating sleeve 3 can drive the outer expanding shaft 7 to adjust the position. The diameter of the outer expanding shaft 7 is greater than that of the pivot part of the motor body 13, thereby providing a larger connection contact area. The plug shaft 6 is inserted into the plug hole 4 of the outer expanding shaft 7, the two sides of the inner embedded block 5 are rectangular planes, and the bottom rectangular opening of the outer expanding shaft 7 cooperates with the rectangular opening, thereby limiting the rotation of the plug shaft 6 and ensuring the stability of the power transmission. By rotating the outer rotating sleeve 3, the axis increasing mechanism can be stably connected as a whole, thereby meeting the installation requirements of the motor shaft diameter of the unmanned aerial vehicle frame, which is the working principle of the motor fixing device installed on the unmanned aerial vehicle frame.

[0035] The embodiments of the present application are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the present application and its practical application, and to thereby enable others skilled in the art to best utilize the present application with various modifications as are suited to the particular use contemplated.
