In combination with Fig. 1, Fig. 3 and Fig. 4, slip gear 300 includes central axis 210, and central axis 210 is arranged in first
Idler wheel 310.Supporting mechanism 400 includes vehicle frame 410 and tension assembly 420, and vehicle frame 410 is set up on central axis 210, vehicle frame 410
One end connect with foot pedal 500, the other end is connect with tension assembly 420, and tension assembly 420 can strut first support arm 340
With second support arm 350, lead to slip gear 300 and wheel to prevent first support arm 340 and second support arm 350 from collapsing
100 are detached from.
Specifically, tension assembly 420 includes support rod 421, the first auxiliary wheel 423 and the second auxiliary wheel 425, support rod
421 connect with vehicle frame 410, and the first auxiliary wheel 423 and the second auxiliary wheel 425 are respectively arranged on the both ends of support rod 421, and first is auxiliary
Wheel 423 is helped to abut with first support arm 340, the second auxiliary wheel 425 is abutted with second support arm 350.
Observation visual angle is shown with Fig. 2, it is assumed that the axle center of the first idler wheel 310 is point O, and the axle center of the first auxiliary wheel 423 exists
Orthographic projection in first support arm 340 is point A, and the axle center of the second idler wheel 320 is point B, first straight line 302 and second straight line 304 it
Between angle be a.Gravity caused by the load born on supporting mechanism 400 is G, and the first auxiliary wheel 423 is to first support arm 340
The pressure of application is F1, and the second auxiliary wheel 425 is F2, F1=F2 to the pressure that second support arm 350 applies.With slip gear
For stress object, by stress analysis it is found that F1=G/2sina.
With the second idler wheel 320 for stress object, B point is supported the thrust F3 of mechanism 400, the pressure F4 of wheel 100, with
And the thrust F5 of first support arm 340.Three power stress balances, to simplify the calculation, if the diameter of the second idler wheel 320 is equal to the first rolling
The diameter of wheel 310, then, and F5=F3*cota.
And for first support arm 340, according to equalising torque it is found that OA*F1=OB*F3, therefore, F3=F1* (OA/
OB).So OA is bigger, F3 is bigger, that is, it is better to reinforce effect closer to B point by point A.
With the first idler wheel 310 for stress object, the pressure F6 for the first support arm 340 that O point is subject to, the second support arm being subject to
350 pressure is the resultant force F8=2F6*cosa of the generation of F7, F6=F7, two power.And F6=F5, it is therefore, finally obtained
It as a result is F8=G* (OA/OB) * (cota)2.When a=45 °, OA=0.5OB, F8=1.5G, it can be seen that in supporting mechanism
The pressure generated under the action of 400 will be significantly greater than the pressure for loading when supporting mechanism 400 is omitted and generating to wheel 100, from
And can increase the frictional force between the first idler wheel 310 and inner surface 110, it is beaten on inner surface 110 to prevent there is the first idler wheel 310
Sliding situation.By above-mentioned analysis it is found that point A is closer to point B, reinforcing effect is better.
Fig. 1, Fig. 3 and Fig. 4 are please referred to, in the present embodiment, supporting mechanism 400 can drive foot pedal 500 along vertical side
To relative to the movement of slip gear 300, vertical direction mentioned here includes the case where being approximately perpendicular to horizontal plane.
Specifically, sliding slot 412 is offered on vehicle frame 410, sliding slot 412 extends along the vertical direction, and central axis 210 is arranged in cunning
Slot 412.When by way of bumpy sections, central axis 210 can be moved along sliding slot 412.And this movement belongs to moment movement, it can't
It causes first support arm 340 and second support arm 350 to collapse, and slip gear 300 and wheel 100 is caused to be detached from.
In order to limit the moving distance of foot pedal 500 radially in wheel 100, the electrodynamic balance vehicle 10 of present embodiment is also
Provided with elastic mechanism (not shown), one end of elastic mechanism is connect with supporting mechanism 400, and the other end and the first idler wheel 310 connect
It connects, elastic mechanism is tension spring, it, which can make supporting mechanism 400 always, has the trend close towards the first idler wheel 310.Work as support
Mechanism 400 along wheel 100 radially away from the first idler wheel 310 when, elastic mechanism can quickly retract supporting mechanism 400, maximum limit
The time isolated with first support arm 340 of the first auxiliary wheel of shortening 423 of degree and the second auxiliary wheel 425 divide with second support arm 350
From time.In addition, elastic mechanism can also make electrodynamic balance vehicle 10 have damping effect, improve in bumpy sections operation
Comfort level.
It is of course also possible to use adjusting the axle center of the first auxiliary wheel 423 and the distance between the axle center of the second auxiliary wheel 425
Mode, to avoid the first auxiliary wheel 423 from separating with first support arm 340 and the second auxiliary wheel 425 divides with second support arm 350
From so that slip gear 300 and wheel 100 be prevented to be detached from.
Specifically, as shown in Fig. 1, Fig. 4 and Fig. 5, support rod 421 includes first connecting portion 4212, elastic component 4214 and the
Two interconnecting pieces 4216, one end of first connecting portion 4212 and the first auxiliary wheel 423 are rotatablely connected, first connecting portion 4212 it is another
End is flexibly connected with one end of second connecting portion 4216, and the other end of second connecting portion 4216 and the rotation of the second auxiliary wheel 425 connect
It connects, one end of elastic component 4214 is connect with first connecting portion 4212, and the other end is connect with second connecting portion 4216.
When supporting mechanism 400 is moved up relative to slip gear 300, it is auxiliary that elastic component 4214 will flick first
Help wheel 423 and second auxiliary wheel 425, with increase between the axle center of the first auxiliary wheel 423 and the axle center of the second auxiliary wheel 425 away from
From, during ensure that supporting mechanism 400 moves up, the first auxiliary wheel 423 is abutted with first support arm 340 always, and second
Auxiliary wheel 425 is abutted with second support arm 350 always.When supporting mechanism 400 declines relative to slip gear 300, first
