[0026] Embodiment

[0027] This embodiment mainly elaborates on the title of the portable UAV landing platform, as follows:

[0028] Referring to the attached Figures 1 - 4 , a special electric wheel for a stacker includes a wheel frame 10 and a plastic outer wheel body 20 sleeved on the side wall of the wheel frame 10. A circumferential notch 100 is provided on the side wall of the wheel frame 10, and a convex part 201 matching the shape of the notch 100 is provided in the middle of the outer wheel body 20. The convex part 201 is attached to the wall surface of the notch 100. In this solution, a notch 100 is provided in the middle of the wheel frame 10 to place the plastic outer wheel body 20 in the notch 100 for axial limitation of the outer wheel body 20 so that it will not fall off axially during use, improving its stability.

[0029] As Figures 2 - 4 shown, the wheel frame 10 includes a detachable left wheel frame 101 and a right wheel frame 102. After the left wheel frame 101 and the right wheel frame 102 are installed, a circumferential notch 100 is formed at the side wall. In this solution, by providing two wheel frames 10, the installation difficulty of the outer wheel body 20 is greatly reduced, and the outer wheel body 20 can be manufactured separately and then installed.

[0030] As Figures 3 - 4 shown, both the left wheel frame 101 and the right wheel frame 102 include outer rings 1011, 1021, support platforms 1012, 1022 and inner rings 1013, 1023. The support platforms 1012, 1022 include several and are located between the outer rings 1011, 1021 and the inner rings 1013, 1023 to connect the outer rings 1011, 1021 and the inner rings 1013, 1023. Among them, the outer rings 1011, 1021 are used to install the outer wheel body 20, the support platforms 1012, 1022 are responsible for support, and the inner rings 1013, 1023 are used to install the wheel axle 30.

[0031] As shown Figure 2 in the figure, mounting holes are provided on the inner rings 1013 and 1023 of the left wheel carrier 101 and the right wheel carrier 102 and are locked by fasteners. During use, the left and right wheel carriers 102 are inserted into the holes in the middle of the outer wheel body 20 to clamp and then the two wheel carriers 10 are locked by fasteners. The fasteners can be screws.

[0032] As shown Figures 3 - 4 in the figure, mounting shaft holes are provided in the middle of the inner rings 1013 and 1023, and bearings 103 for mounting the wheel shaft 30 are arranged in the mounting shaft holes of the two inner rings 1013 and 1023. The two bearings 103 have the same size. When installing the wheel shaft 30, insert it so that it has an interference fit with the bearing 103.

[0033] As shown Figure 4 in the figure, the side walls of the left wheel carrier 101 and the right wheel carrier 102 have left and right symmetrical left and right curved surfaces, and the left and right curved surfaces are used for axially limiting the outer wheel body 20. The two curved surfaces are used to abut against the inner side wall of the outer wheel body 20 for limiting.

[0034] As shown Figure 4 in the figure, the cross section of the notch 100 is an isosceles trapezoid or a V shape. In the case of an isosceles trapezoid, the middle part has an interference fit with the outer wheel body 20, while in the case of a V shape, the outer wheel body 20 needs to be clamped by the curved surfaces on both sides. When necessary, an adhesive layer can be added at the notch 100 to fix the outer wheel body 20.

[0035] As shown Figure 4 in the figure, annular limiting platforms 104 extending radially outward are provided at the left end of the left wheel carrier 101 and the right end of the right wheel carrier 10. The annular limiting platforms 104 are abutted against the end wall surface of the outer wheel body 20. The abutment of the limiting platform 104 against the end wall surface of the outer wheel body 20 further increases the strength of the limit. The outer diameter of the limiting platform 104 is smaller than the outer diameter of the outer wheel body 20.

[0036] Preferably, the support platforms 1012 and 1022 on the left wheel carrier 101 and the support platforms 1012 and 1022 on the right wheel carrier 102 are arranged in a staggered manner and there is an overlapping part for each adjacent projection in the axial projection of each support platform 1012 and 1022. In this way, in the circumferential direction, the support platforms 1012 and 1022 form a gapless support, which is beneficial to improving the load-bearing capacity.

[0037] Preferably, the wheel carrier 10 is a metal frame and the outer wheel body 20 is a plastic wheel body. The plastic wheel body is generally a polyurethane wheel body.

[0038] The above has introduced in detail the title of a special electric wheel for a stacker provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
