A kind of balance car car bar and balance car
Technical field
The present invention relates to balance car control field, in particular, relate to a kind of balance car car bar and balance car.
Background technology
Electrodynamic balance car, is again body-sensing car, thinking car, and its operation principles is mainly built upon one and is referred to as " the most steady
In ultimate principle calmly ", utilize gyroscope and the acceleration transducer of vehicle body, detect the change of vehicle body attitude, utilize
Servo-control system, accurately drives motor to be adjusted correspondingly, to keep the balance of system.
Existing electrodynamic balance car typically has two kinds, and one is to have an action bars on car body, and user stands in electronic
On the foot platform of balance car operating action bars, thus advance, retreat and stop, such control is also referred to as " manual ".
Another kind is that car body is made up of two parts, realizes mutually rotating by rotating mechanism, thus realize between left half and right half
" foot control ".
The balance car car pole length of existing band car bar is changeless, and the people of the most specific height can obtain preferably
Driving experience, but for superelevation crowd, or the ultralow crowd such as child cannot be suitable for.
Summary of the invention
The technical problem to be solved be to provide a kind of crowd being applicable to different height balance car car bar and
Balance car.
It is an object of the invention to be achieved through the following technical solutions:

Balance car wheel fixing mechanism and the balance car of the embodiment of the present invention are described below with reference to Fig. 1 to Figure 12.
The balance car car bar of present embodiment includes the sleeve pipe 91 that the car body with balance car is connected, with sleeve pipe 91 nested arrangements
Expansion link 92;Described sleeve pipe 91 is provided with the elastic component 93 for banding expansion link 92 at opening part;Described expansion link 92 with
The end that sleeve pipe 91 coordinates is provided with the pressed component 94 compressing elastic component 93.Loop bar top is provided with handle 99.
Optionally, described elastic component 93 includes and the socket part 931 of expansion link 92 socket, is connected with socket part 931
Threaded portion 932;Described threaded portion 932 sidewall is provided with breach 934, and the aperture of described threaded portion 932 opening part is less than the mouth of root
Footpath, described socket part 931 and junction, threaded portion 932 are formed with the anchor ring 933 propping up sleeve pipe 91 end face;Described pressed component 94
For setting the hollow circular-tube that female and described threaded portion 932 coordinates, described expansion link 92 is through elastic component 93 and pressure
Tight component 94 is embedded in sleeve pipe 91.
Optionally, described socket part 931 inwall is provided with the first rib 95 of projection;Described sleeve pipe 91 outer wall has been provided with first
The first groove 96 that rib 95 coordinates;Described first groove forms the second rib 97 at the inwall of sleeve pipe 91;Described expansion link 92
Outer wall is provided with the second groove 98 coordinated with the second rib 97.
Present embodiment is also disclosed a kind of wheel securing structure, and this wheel securing structure includes including hollow body 10;Hollow
Spring 20 it is provided with in body 10;Movable axis 30 it is arranged with in spring 20;Movable axis 30 one end is flexibly connected with wheel shaft 50, the other end
Prop up spring 20;Described wheel shaft 50 can sheathed entrance hollow body 10 inside.
Optionally, the opening part of hollow body 10 is arranged with cap sleeve 40;The aperture of described cap sleeve 40 is less than the hollow mouth of pipe
Internal diameter;One end that described spring 20 closes on wheel shaft 50 is pushed against the inward flange of cap sleeve 40 opening.Cap sleeve 40 is threadedly secured to
Hollow body 10 opening part.With portable propelling axle 30, the dismounting of spring 20, and can be coordinated with movable axis 30 by cap sleeve 40
Form the location structure of spring 20.
Cap sleeve 40 inside top surface and bottom surface are plane 70;Accordingly, movable axis 30 upper and lower surface is also plane
70, form, with cap sleeve 40 inside top surface and bottom surface, the position limiting structure that restraint axle 30 rotates.Utilize the internal diameter of cap sleeve 40
Movable axis 30 is carried out spacing by shape, prevents rotating shaft 32 from rotating, and so need not arrange position limiting structure in hollow body 10 again, reduce
Manufacturing cost.
The length of described wheel shaft 50 is more than the bore of described cap sleeve 40.The when that so rotating shaft 32 being vertical with cap sleeve 40, i.e.
The stress utilizing spring 20 wheel 60 folds when is stuck in cap sleeve 40 opening part, it is achieved be automatically positioned.
Described movable axis 30 is provided with groove 31 with the fixing one end of wheel shaft 50;It is provided with rotating shaft between 31 liang of inwalls of described groove
32;Accordingly, described wheel shaft 50 embeds in groove 31;Described wheel shaft 50 is provided with the through hole of sheathed rotating shaft 32;When wheel shaft 50 rotates
To time parallel with movable axis 30, it is internal that rotating shaft 32 can be embedded into hollow body 10 together with movable axis 30;When rotating shaft 32 turn to
When movable axis 30 is vertical, rotating shaft 32 is pushed against cap sleeve 40 opening part.
Wheel shaft 50 includes the fixed part 51 coordinated with described groove 31, the pedestal 52 being connected with fixed part 51;Described activity
The axle 30 end face in groove 31 one end is inner concave arc surface 34;Described pedestal 52 is provided with and inner concave arc surface 34 with fixed part 51 junction
Adaptive outer convex globoidal 53.Cambered surface is conducive to reducing friction during rotating axle 50.
One end that described movable axis 30 is relative with wheel shaft 50 connects disk 33;The external diameter of described disk 33 and hollow body
The internal diameter of 10 is consistent.So after the sheathed spring of movable axis 30 20, spring 20 tail end just can prop up disk 33, returning by spring 20
Elastic force drags movable axis 30 toward hollow body 10 internal motion.
Optionally, the present invention the most not necessarily wants cap sleeve 40, is directly internally formed spring 20 and activity at hollow body 10
The location structure of axle 30 is also feasible.So parts are less, more compact structure some.Specifically, hollow body 10 is internal
Use non-circular structure, ellipse, rectangle etc. can be used, it is of course also possible to be set to plane at internal end face and bottom surface
70;Accordingly, movable axis 30 upper and lower surface is also plane 70, is formed with hollow body 10 inside top surface and bottom surface
The position limiting structure that restraint axle 30 rotates;Then the opening part at hollow body 10 arranges the edge of indent, is used for positioning bullet
Spring 20.Now, the length of wheel shaft 50 is more than the internal diameter of described hollow body 10.The structures such as movable axis 30, wheel shaft 50 are referred to
Previously mentioned, do not repeat them here.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
