And the pin 202 being slidably matched therewith, the connecting rod 61 have a press section 612, during the state of emergency, make the operating handle 6
Swing backward, so that the press section 612 presses the button on the sentinel plant 5.
Summary, the operation principle of the anti-turning-up devices 100 of balance car of the present invention is described in detail below, it is as follows：
With reference to shown in Fig. 3 and Fig. 6, when the balance car 200 is in normal operating condition, the undercarriage 1 is to pack up shape
State, now, the electric pushrod 40 is contraction state, and the opening 351 of the buckling piece 35 is downward and the opening 351 is buckled in institute
State on pivot pin 33, the electromagnet 39 be that normal open is electric and the magnetic attraction of the electromagnet 39 described in locking piece 34；Magnetic force is big
In the elastic force of second elastic component 38, make the locking piece 34 close to the buckling piece 35, and cause the locking piece
Engaging tooth 341 on 34 engages with the cooperating teeth 353 on the buckling piece 35；At this moment, first elastic component 37 is in relaxation shape
State, second elastic component 38 is in impaction state, and the swing component 2 has swung certain angle, and the 3rd elastic component 4 is in
Tension；In addition, the operating handle 6 makes the press section 612 leave the sentinel plant 5 away from the sentinel plant 5
Button；In the above-described state, the rotating shaft 31 is in the lock state, it is impossible to is rotated.
With reference to shown in Fig. 7 and Fig. 8, when the dead battery of balance car 200 or in case of emergency need to use is risen and fallen
During frame 1, the button or the operation operating handle 6 of the sentinel plant 5 can be manually pressed by, make the operating handle 6 to
After swing, and then the press section 612 is pressed the button；At this moment, the sentinel plant 5 is i.e. disconnected to the electromagnet 39
Electricity, the magnetic field of the electromagnet 39 disappear, and under the elastic force effect of second elastic component 38, the locking piece 34, which rotates, makes institute
State engaging tooth 341 and depart from the cooperating teeth 353, now, the buckling piece 35 is discharged, and unlocks the rotating shaft 31, in institute
Under the resilient force for stating the 3rd elastic component 4, the rotating shaft 31 is rotated, and the rotating shaft 31 is commonly used described in drive by the fixation
Pivot pin 33 rotates and under the resilient force power of first elastic component 37, and the buckling piece 35 rotates again, so as to
The pivot pin 33 is set slowly to depart from the opening 351；At the same time, the swing component 2 follows the rotating shaft 31 and swung, and makes institute
Undercarriage 1 is stated to fall.In addition, the electric pushrod 40 starts when the rotating shaft 31 unlocks, the electric pushrod 40 stretches
End is slowly stretched out, and promotes the cursor 36 to rotate, and the cursor 36 drives the opening 351 of the buckling piece 35 close
The pivot pin 33, until the opening 351 fastens with the pivot pin 33 again, at this moment, the press section 612 of the operating handle 6
The button is left again, the electromagnet 39 is powered, and the electromagnet 39 produces locking piece 34 described in magnetic attraction, and then makes
The engaging tooth 341 is engaged with cooperating teeth 353 again, and now, the buckling piece 35 is fixed, and locks the rotating shaft 31, described
When rotating shaft 31 is in locking, the undercarriage 1 is in the state for falling and fixing, to ensure the security used.It is above-mentioned due to
The whereabouts of the undercarriage 1 is flashy after the rotating shaft 31 unlocks, and the action of the electric pushrod 40 is slowly to carry out
, therefore, the undercarriage 1 can first be unlocked and deployed, and be then fixed on again by being locked under the pushing tow of electric pushrod 40
Deployed condition.
With reference to shown in Fig. 9 and Figure 10, when needing to pack up the undercarriage 1, it is only necessary to start the electric pushrod 40, make
The telescopic end of the electric pushrod 40 shrinks, and the electric pushrod 40 drives the cursor 36 to rotate down, the cursor
36 drive the buckling piece 35 and locking piece 34, because the opening 351 of the buckling piece 35 fastens the pivot pin 33, therefore, institute
Stating buckling piece 35 drives the pivot pin 33 to be rotated around the rotating shaft 31, and by the fixed arm 32, the rotating shaft 31 rotates, institute
State rotating shaft 31 and drive the swing component 2, the swing component 2 is swung to original angle again, pass through the company of the undercarriage 1
Moving part 12, the support arm 11 drive the safety wheel 13 to be swung up, and the undercarriage 1 is packed up completely, the balance car is prevented
Turning-up devices 100 turn again to normal operating condition.
Compared with prior art, because the present invention in the forward and backward side of balance car 200 by setting the undercarriage 1, and
The undercarriage 1 is connected with the rotating shaft locking mechanism 3 by swing component 2, therefore, by controlling the rotating shaft locking mechanism
The power on/off of 3 electromagnet 39, you can realize the unblock and locking to the rotating shaft 31；It is described when the rotating shaft 31 unlocks
Under drive of the swing component 2 by the 3rd elastic component 4, the undercarriage 1 is fallen, balance car 200 is kept balance；Further through institute
The flexible of electric pushrod 40 is stated, the rotating shaft 31 can be made to lock automatically, and the undercarriage 1 is packed up；Whole device is only
The power on/off of control electromagnet 39 is needed, it is easy to use, when the electricity of the battery of balance car 200 exhausts, the electromagnet
39 can automatically power off, and undercarriage 1 is fallen automatically, and the safety of balance car 200 has been effectively ensured, and prevent from overturning.
The above disclosed right model for being only the preferred embodiments of the present invention, the present invention can not being limited with this certainly
Enclose, therefore the equivalent variations made according to scope of the present invention patent, still fall within the scope that the present invention is covered.
