Description
Technical field
The present invention relates to a kind of balance car, more particularly to a kind of anti-turning-up devices of balance car.
Background technology
Automatic balance car be a kind of driven by power, have homeostasis function new personal auxiliary maneuvering device, its work
As mode " dynamic stability " principle is based primarily upon, i.e., the posture shape residing for vehicle body is judged with built-in accurate solid-state gyroscope
State, after calculating appropriate instruction through accurate and high speed central microprocessor, motor accomplishes the effect of balance.Reason
By upper, correctly turn on the power as long as automatic balance car has and the electric power of enough runnings can be kept, the driver on car does not just have to load
The heart has the possibility toppled over and fallen.
But any electronic equipment, mechanical device and battery can all run into various problems in actual use, when automatic flat
Weigh built-in gyroscope or the processor damage of car, either its mechanical structure is destroyed or during dead battery capability, automatic flat
Weighing apparatus car will lose homeostatic function, if now automatic balance car is in a faster speed, overturning just occurs
Danger, the personal safety to driver cause damage；In addition, can also there are technical requirements to driver, for handicapped or behaviour
Make for not yet done user, existing balance car is inconvenient for use and has certain danger.
The content of the invention

The swing backward of hand 6, 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 are in impaction state, and the swing component 2 has swung certain angle, and the return unit 4 is in tension
State；In addition, the operating handle 6 away from the sentinel plant 5, make the press section 612 leave the sentinel plant 5 by
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 return unit 4, the rotating shaft 31 rotates, and the rotating shaft 31 drives the pivot pin by the fixed arm 32
33 rotate and under the resilient force power of first elastic component 37, and the buckling piece 35 rotates again, so that institute
State pivot pin 33 and slowly depart from the opening 351；At the same time, the swing component 2 follows the rotating shaft 31 and swung, and makes described rise
Fall frame 1 to fall.In addition, the electric pushrod 40 starts when the rotating shaft 31 unlocks, the telescopic end of the electric pushrod 40 is slow
It is slow to stretch out, and promote the cursor 36 to rotate, the cursor 36 drives the opening 351 of the buckling piece 35 close to described
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 again from
The button is driven, the electromagnet 39 is powered, the electromagnet 39 produces locking piece 34 described in magnetic attraction, and then makes described
Engaging tooth 341 is engaged with cooperating teeth 353 again, and now, the buckling piece 35 is fixed, and locks the rotating shaft 31, the rotating shaft
31 in when locking, and the undercarriage 1 is in the state for falling and fixing, to ensure the security used.It is above-mentioned to work as the pendulum
The divergent ends of moving part 2 and the moving part 12 in line when, at this moment the undercarriage 1 falls completely, moving part 12 at this moment
A stable state is formed with swing component 2 and support arm 11, ensures the safety of driving.It is described after the above-mentioned unblock due to the rotating shaft 31
The whereabouts of undercarriage 1 is flashy, and the action of the electric pushrod 40 is slowly carried out, therefore, the meeting of undercarriage 1
First unlock and deploy, be then fixed on deployed condition by being locked under the pushing tow of electric pushrod 40 again.
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 return unit 4, the undercarriage 1 is fallen, balance car 200 is kept balance；Further through the electricity
Stretching for dynamic push rod 40, can be such that the rotating shaft 31 locks automatically, and the undercarriage 1 is packed up；Whole device only needs
The power on/off of electromagnet 39 is controlled, it is easy to use, when the electricity of the battery of balance car 200 exhausts, the meeting of electromagnet 39
Automatically power off, undercarriage 1 is fallen automatically, the safety of balance car 200 has been effectively ensured, 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.
