Demonstrate,prove the safety that balance car 200 is driven a vehicle.The balance car 200 is equipped with the locating part 201, the surface of the locating part 201
With bolster, the locating part 201 is located at the top of the moving part, and when the undercarriage 1 falls, the swing component 2 is swung
Certain angle, the locating part 201 limits the swing component 2 and excessively swings, and prevents from touching with the swing component 2 by bolster
It hits.The sentinel plant 5 is installed on balance car 200, and the sentinel plant 5 is electrically connected with the electromagnet 39 and controls institute
The power on/off of electromagnet 39 is stated, the energized state of the electromagnet 39 is normal open electricity.It is described by the way that the sentinel plant 5 is arranged
Sentinel plant 5, which can be set, to be driven near envoy, is conveniently driven envoy and is operated in time, guarantee when driving encounters emergency episode can and
When react.The lower end of the operating handle 6 is articulated in the front end of the balance car 200, has on the operating handle 6 and connects
Extension bar 61, the connecting rod 61 are equipped with elongated hole 611, and the front end of the balance car 200, which is equipped with, is plugged in the elongated hole 611
And the pin 202 being slidably matched therewith, the connecting rod 61 have press section 612, when the state of emergency, make the operating handle 6
It swings backward, so that the press section 612 presses the button on the sentinel plant 5.
In summary, the working principle of the anti-turning-up devices 100 of balance car of the invention is described in detail below, as follows:
In conjunction with 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, at this point, the electric pushrod 40 is contraction state, the opening 351 of the fastener 35 is downward and the opening 351 is buckled in institute
It states on pivot pin 33, the electromagnet 39 is locking piece 34 described in normal open electricity and the magnetic attraction of the electromagnet 39；Magnetic force is big
In the elastic force of second elastic component 38, make the locking piece 34 close to the fastener 35, and makes the locking piece
Engaging tooth 341 on 34 is engaged with the cooperating teeth 353 on the fastener 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 third elastic component 4 is in
Tension；In addition, the operating handle 6 makes the press section 612 leave the sentinel plant 5 far from the sentinel plant 5
Button；In the above-described state, the shaft 31 is in the lock state, and is not able to rotate.
In conjunction with shown in Fig. 7 and Fig. 8, when 200 dead battery of balance car or in case of emergency need using rising and falling
When 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 made to press the button；At this moment, the sentinel plant 5 is i.e. disconnected to the electromagnet 39
The magnetic field of electricity, the electromagnet 39 disappears, and under the elastic force effect of second elastic component 38, the rotation of locking piece 34 makes institute
It states engaging tooth 341 and is detached from the cooperating teeth 353, at this point, the fastener 35 is discharged, unlock the shaft 31, in institute
Under the resilient force for stating third elastic component 4, the shaft 31 is rotated, and the 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 fastener 35 rotates again, thus
The pivot pin 33 is set slowly to be detached from the opening 351；At the same time, the swing component 2 follows the shaft 31 and swings, and makes institute
State the whereabouts of undercarriage 1.In addition, the electric pushrod 40 starts when the shaft 31 unlock, the electric pushrod 40 stretches
End is slowly stretched out, and the cursor 36 is pushed to rotate, and the cursor 36 drives the opening 351 of the fastener 35 close
The pivot pin 33, until it is described opening 351 again with the pivot pin 33 fasten, at this moment, the press section 612 of the operating handle 6
The button is left again, the electromagnet 39 is made to be powered, and the electromagnet 39 generates locking piece 34 described in magnetic attraction, and then makes
The engaging tooth 341 is engaged with cooperating teeth 353 again, at this point, the fastener 35 is fixed, locks the shaft 31, described
When shaft 31 is in locking, the undercarriage 1 is in the state for falling and fixing, to guarantee the safety used.It is above-mentioned due to
The whereabouts of the undercarriage 1 is flashy after the shaft 31 unlocks, and the movement of the electric pushrod 40 is slowly to carry out
, therefore, the undercarriage 1 can be unlocked first and is unfolded, and be then fixed on again by being locked under the pushing tow of electric pushrod 40
Unfolded state.
In conjunction with 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 is shunk, and the electric pushrod 40 drives the cursor 36 to rotate down, the cursor
36 drive the fastener 35 and locking piece 34, since the opening 351 of the fastener 35 fastens the pivot pin 33, institute
Stating fastener 35 drives the pivot pin 33 to rotate around the shaft 31, and by the fixed arm 32, the shaft 31 is rotated, institute
It states shaft 31 and drives the swing component 2, the swing component 2 is made to swing 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 pack up the undercarriage 1 completely, and the balance car is anti-
Turning-up devices 100 turn again to normal operating condition.
Compared with prior art, the undercarriage 1 is arranged by the forward and backward side in balance car 200 due to the present invention, and
The undercarriage 1 is connect with the rotating shaft locking mechanism 3 by swing component 2, therefore, by controlling the rotating shaft locking mechanism
Unlock and locking to the shaft 31 can be realized in the power on/off of 3 electromagnet 39；It is described when the shaft 31 unlock
Under the drive that swing component 2 passes through third elastic component 4, the undercarriage 1 is made to fall, balance car 200 is made to keep balance；Further through institute
The flexible of electric pushrod 40 is stated, the locking automatically of shaft 31 can be made, and the undercarriage 1 is packed up；Whole device is only
Need to control the power on/off of electromagnet 39, it is easy to use, when the electricity of 200 battery of balance car exhausts, the electromagnet
39 can automatically power off, and so that undercarriage 1 is fallen automatically, the safety of balance car 200 has been effectively ensured, has prevented from overturning.
The above disclosure is only a preferred example of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, still falls within the range that the present invention is covered.
