Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Describing, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on this reality
By the embodiment in novel, art technology those of ordinary skill is in the every other reality not paying creative work and obtain
Execute mode, broadly fall into the scope of this utility model protection.
As in Figure 2-4, it is shown that the steering wheel of embodiment one of the present utility model.Fig. 2 be the steering wheel of embodiment one just
View, Fig. 3 is the left view of the steering wheel of embodiment one, Fig. 4 a and steering wheel the facing when rotation status that Fig. 4 b is embodiment one
Figure.
As in Figure 2-4, the steering wheel of embodiment one, described steering wheel includes:
Shell, described shell includes drive end bearing bracket 501, main body 1 and rear end cap 502, drive end bearing bracket 501, main body 1 and rear end cap
502 link together, and connected mode is it may be that as in figure 2 it is shown, connect by screw 8 and on drive end bearing bracket 501 and rear end cap 502
Screw hole be counterbore so that screw terminal does not protrude from the surface of forward and backward end cap, it is of course also possible to select be connected together, bonding
It is attached Deng conventional alternative；
Wherein, drive end bearing bracket 501 is provided with the output shaft hole passed for steering wheel output shaft 7.
Wherein, main body 1 includes that top 2, described top 2 include a planar portions 201 and two curved portions 202, two arcs
Shape portion 202 links together with left part 601 and right part 602 respectively.
As Figure 2-3, the outline of the cross section at the top of the top of described drive end bearing bracket 501 and described rear end cap 502
Shape all outer contour shapes with the cross section at the top 2 of described main body 1 are identical, it is preferable that drive end bearing bracket 501 and rear end cap

From less than the axis of steering wheel output shaft 7 and the beeline being connected between flat board 301, it is at or about at this point it is possible to obtain
The rotational angle of ± 90 °.If needing acquisition to exceed the ± rotational angle of 90 °, the then axis of steering wheel output shaft 7 and main body 1
The distance of left part 601, the axis of steering wheel output shaft 7 and the distance of the right part 602 of main body 1 and the axle of steering wheel output shaft 7
Longest distance between line and top 2, all should be less than the axis of steering wheel output shaft 7 and the short distance being connected between flat board 301
From.Additionally, in order to obtain bigger rotational angle, it is also possible to suitably reduce the size connecting flat board 301, such as, reduce along hanging down
Straight size on steering wheel output shaft 7 direction, so that the side connecting flat board 301 will not stop steering wheel itself.
As shown in Figure 5, it is shown that a kind of steering wheel of this utility model embodiment two, the shape of two curved portions 202 and arc
Degree can be different, and two curved portions 202 can not be symmetrically arranged.When actual condition has only to rotate to a direction
Time, can be with only one of which curved portions 202, remaining non-detailed portion is identical with embodiment one.
As shown in Figure 6, it is shown that a kind of steering wheel of this utility model embodiment three, wherein, top 2 is arc, and remaining is not
Detailed portion is identical with embodiment one.
A kind of steering wheel provided this utility model above is described in detail, used herein be specifically isolated right
Principle of the present utility model and embodiment are set forth, and the description of above example is only intended to help and understands this utility model
Inventive concept；For persons skilled in the art, according to design of the present utility model, at detailed description of the invention and application model
Place and all will change.In sum, this specification content should not be construed as restriction of the present utility model.
