Hereinafter, a folding and unfolding process of the electric car 1 having the seat angle correcting device constructed as described above will be described with reference to the drawings.

In order to fold the electric car 1, as shown in FIG. 6, the backrest 520 of the seat part 500 is first folded, and at this time, it can be folded manually or automatically.

When the folding switch 432 is selected as the folding mode, the folding process is started. The detection sensor installed on the seat 510 detects whether a passenger or an object is present on the seat 510, The installed tilt sensor senses the tilt of the electric car 1 placed on the road surface. The sensor 600 senses the sensed signal and the tilt value sensed by the tilt sensor is transmitted to the controller 600. The controller 600 determines whether the occupant is seated or not, It is determined whether or not it is in a state suitable for the folding process.

At this time, if the detection sensor senses an object placed on the seat 510 or the seat 510 sitting on the seat 510, or if the tilt value sensed by the tilt sensor is greater than or equal to the reference value, the controller 600 can not perform the smooth folding process.

Conversely, in order to unfold the electric car 1, if the folding switch 432 is first selected as the unfolding mode, the unfolding process is started and the lock of the latch from the folded electric car is released.

The tilt sensor installed on the seat 510 senses the tilt of the electric car 1 placed on the road surface and the tilt value sensed by the tilt sensor is transmitted to the controller 600. Based on this, It is judged whether or not the slope of the electric motor is suitable for unfolding process.

At this time, if the slope value detected by the tilt sensor is equal to or greater than the reference value, the smooth unfolding process can not be performed, so that the controller 600 sounds an alarm sound and stops the unfolding process.

On the other hand, if the slope value detected by the tilt sensor is less than the reference value, the controller 600 continues the folding process of the next step.

Next, the controller 600 operates the braking actuator 231 to brak the front wheel 210 to fix the front wheel so that the front wheel is not moved and steered, and the angle correction actuator (not shown) of the seat angle correcting device 700 7 is operated to move the seat portion 500 upward through the control rod 720. When the driving means 330 is operated to move the rear wheel 310 backward, do.

After the backrest 520 is opened, the occupant sits on the seat 510 and grips the handle 420 to release the braking actuator 231 from the acceleration lever and the hand The brake can be operated to move to the desired position.

10, when the occupant climbs uphill on the electric car 1, as shown in FIG. 12A, the seat angle correcting device 700 of the electric car 1, The tilt sensor installed on the controller 500 senses the tilt of the electric motor 1 and transmits a sensing signal to the controller 600. When the received tilt value is within the reference value range, The control unit 710 is operated to move the control rod 720 upward to control the seat 510 in a horizontal state so that the occupant ascends the ascending path to the electric car 1 and enters the flat surface, When the received tilt value is out of the reference value range, the angle correcting actuator 710 is operated to move the control rod 720 downward, and the sheet 510 returns to the original state.

On the other hand, as shown in FIG. 12B, when the passenger descends down the electric car 1, a tilt sensor installed on the seat portion 500 senses the inclination of the electric car 1 and outputs a detection signal to the controller 600 The controller 600 operates the angle correction actuator 710 in accordance with the received tilt value to move the control rod 720 downward to control the seat 510 to be in a horizontal state, The controller 600 moves the control rod 720 to the upper side by operating the angle correction actuator 710 when the tilt value received from the tilt sensor is out of the reference value range by moving down the downward road, 510 return to the original state.

As described above, since the vertical angle of the seat 510 on which the passenger sits is automatically adjusted in accordance with the inclination of the electric car 1 in the electric car 1, the passenger can maintain the correct horizontal posture even on the ascending or descending road, You can move comfortably.

At this time, the controller 600 determines whether the inclination value detected by the inclination sensor is within the reference value range. If the inclination value is within the reference value range, the controller 600 determines that the inclination value is an uphill or downhill road, The occupant can maintain the horizontal posture by operating the angle correction actuator 710. If the inclination value is out of the reference value range, the seat angle is not corrected by judging to be flat.

In addition, by setting the angle correction actuator 710 of the seat angle correcting apparatus 700 to be operated only when the slope value of the uphill or downhill within the reference value range is maintained over the reference time, the component durability of the electric car is increased, Frequent posture control is prevented, so that the occupant can ride in a comfortable and stable posture.

For example, when there is a small groove with a tuck or a depression, the tilted inclination is immediately canceled. Thus, if the seat angle correcting apparatus 700 is operated until such a time, the occupant becomes uneasy.

As a result, the electric car 1 having the seat angle correcting device according to the present invention can be folded and stored in a compact, compact size, can be moved, moved and moved, can be moved using an obstacle area such as a staircase and public transportation, Since the folding and unfolding automatically folds and unfolds quickly and conveniently, and the vertical angle of the seat in which the occupant sits in the electric car is automatically adjusted according to the inclination of the electric car, the passenger can maintain the correct horizontal posture even on an uphill or downhill road. It is safe and comfortable to move.
