Detailed description of the invention
Below in conjunction with accompanying drawing illustrated in greater detail embodiments of the present invention, embodiments of the invention are to explain explanation further to the present invention, but not limit protection scope of the present invention.
Embodiment one
Refer to shown in Fig. 1 and Fig. 2, electrodynamic balance car of the present invention comprise wheel 1, the housing 2 be covered on wheel, lay respectively at wheel 1 both sides two stretchers 3, be installed on power supply 4 in housing and control system.
Please again shown in composition graphs 3 and Fig. 4, described wheel 1 comprises wheel rim 11, electric machine assembly and two connecting elements 12.Certainly, two connecting elements 12 also can not as the parts of wheel, only can regard the Connection Element of stretcher 3 and wheel as, in the present embodiment, are still considered as wheel and comprise connecting element and describe.Described electric machine assembly comprises stator 13, is arranged at the rotor 14 of stator 13 periphery, two bearings 15, two attaching parts 16.Stator 13 comprises inner ring body 131 and is arranged at the winding body 132 of inner ring body 131 periphery.Inner ring body 131 surrounds a cavity 130.Winding body 132 is in order to coil around the home.The width of inner ring body 131 on stator shaft orientation of stator 13 is greater than the width of winding body 132 on stator shaft orientation, so the middle part of inner ring body 131 arranges outside winding body 132, the both ends of inner ring body 131 can also be nested with bearing 15.The axis of described stator 13 that is the axis of wheel 1, the axis of wheel 1 refers to the direction vertical with wheel rolling direction, and in other words, imaginary wheel 1 rotates around an axle, and the bearing of trend of this axle is exactly axially.Described winding body 132 is positioned at the middle part of inner ring body 131, and the inner ring 151 of two bearings 15 is placed on the two ends of inner ring body 131 respectively and for closely cooperating, namely the inner ring 151 of bearing 15 fixes with inner ring body 131.Rotor 14 comprises steel ring 141 and is arranged at the some magnet 142 inside steel ring.The steel ring 141 of rotor 14 can be one-body molded with wheel rim 11, also can shaping respectively after be fixed together, can also using wheel rim 11 directly as rotor steel ring 14, namely the inner side of wheel rim 11 posts some described magnet 142.In the present embodiment, described wheel rim 11 is provided with two can the wheel rim of mounting tyre, and namely the wheel of present embodiment is two rim wheels.
Described every a connection piece 16 is provided with can engaging body 161 close-fitting with the outer ring 152 of bearing 15, and the outer ring 152 that this engaging body 161 is fastened in corresponding bearing 15 can be rotated together with outer ring 152, and namely outer ring 152 is fixedly connected with engaging body 161.The outer rim of attaching parts 161 is provided with the through hole 162 that some appearance screws or the fastener such as bolt or stud pass through, and attaching parts 161 is fixedly connected with wheel rim 11 or rotor 14 by fastener.Attaching parts 16 is annular, and described cavity 130 runs through two attaching partss 16 respectively to both sides.
Each connecting element 12 described comprises annular main body 121, pedal connector 122 and fixed body 123.Main body 121 is provided with the through hole 120 that some appearance screws or the fastener such as bolt or stud pass through, and connecting element 12 is fixedly connected by the inner ring body 131 of fastener and stator.Pedal connector 122, fixed body 123 can be one-body molded with main body 121, also can shaping respectively after link together.Pedal connector 122 is positioned at the bottom of wheel in order to installation foot pedal 3.Fixed body 123 is positioned at the top of wheel in order to be fixedly connected with housing 2.Because the diameter of the main body 121 of connecting element is suitable with the diameter of stator inner ring body 131, described cavity 130 can run through fixed body 12 completely, certainly, the diameter of main body 121 also can be slightly less than the diameter of inner ring body 131, namely main body 121 blocks the outer peripheral portion of cavity 130, and cavity 130 centre portion runs through fixed body 12.So at least wheel 1 is run through at the middle part of cavity 130, naturally run through electric machine assembly.What is called runs through in the part that refers to and run through does not have structure member, so can reduce the weight of wheel, increases the portability of car body.
Shown in Fig. 1 and Fig. 2, described housing 2 is provided with the supporter 21 be positioned at above wheel, and this supporter 21 is extended with the hold-down arm 22 be fixedly connected with the fixed body 123 of two connecting elements 12 respectively downwards.Housing 2 is fixedly connected on wheel 1 by hold-down arm 22.The top of supporter 21 is provided with receiving space 20, and the circuit card, electronic component etc. of power supply 4 and control system are installed in this receiving space 20.Housing 2 is provided with the cylindrical body 23 protruded in described cavity 130, so housing 2 is run through at the middle part of cavity 130, namely the middle part of electrodynamic balance car wheel of the present invention does not have structure member, there is no the parts such as axletree of the prior art, be conducive to the weight reducing wheel, increase the portability of car body.
Housing 2 can also be provided with handrail 5, and in the present embodiment, handrail 5 is set to one and is installed on expansion link on housing 2, when riding, can move suitable length to, during collection, can be contracted to most short status.
Embodiment two
Refer to shown in Fig. 5, which show the second embodiment of electrodynamic balance car of the present invention.Be with the first embodiment difference, the wheel rim 11 of wheel 1 is single rim wheel.
Certainly, the above is the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
