[Technical field to which the invention belongs]

 The present invention relates to a drive control apparatus for a kickboard with a motor, and particularly when exercising using a kickboard, performs a timely start and stop of a motor by a rotation speed difference generated from a tire and simultaneously protects a circuit. Belongs to technology.

[0002]

[Prior art]

 In a conventional kick board having a known structure, as shown in FIG. 1, a power switch and a speed control device C are provided between a motor A and a battery B, and a brake device D provided additionally is used. The brakes are applied to the tires in a timely manner. The power of the motor A is used for driving or stopping the kick board.

[0003]

[Problems to be solved by the invention]

 However, the kick board having the known structure as described above has the following disadvantages. First, when the power switch and the speed control device are activated, the motor is ready to move with the power supply at any time, and the magnitude of the input current is changed by the modulation of the power switch and the speed control device, and Since the rotation speed of the motor is controlled, even when the kick board is temporarily stopped or moving slowly, the electric power is consumed at any time. Also, when the kick board is stationary and it is about to exercise, it usually requires a large amount of force, and the user takes the required maximum current value of the motor with the power switch and the speed control device. Therefore, it can be said that when the motor is started, the electric power is greatly consumed and it is uneconomical. Also, as described above, when the power switch and the speed control device are on, that is, the motor is receiving electricity, and the user should inadvertently operate the power switch and the speed control device. If touched, there is a risk that the kickboard will suddenly start. Further, when the user attempts to decelerate by controlling the power of the motor using the brake device, since the motor is still receiving electricity, the speed of the deceleration is very slow. In other words, the distance to stop after braking is naturally longer. Further, the motor is ready to exercise by receiving electricity at any time when the power switch and the speed control device are on, so that the user cannot manually move the kick board, and Not suitable for use for exercise. SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned drawbacks, and to provide a kickboard powered drive control device that can be easily started and operated, prevents power consumption, and is safe. Things.

[Means for Solving the Problems]

 The invention according to claim 1 comprises at least a relay, a starting and protection circuit, a protection circuit corresponding to a voltage that is too low, a power switch and a speed control circuit, and a brake unit in a powered kickboard including a battery and a motor. In the drive control device, one end of the relay is connected to a battery, and when the power switch and the speed control circuit are activated, the relay is in a circuit state, and the user first presses the kick board manually to move the tire. As a result, the motor rotates, the coil and the armature inside the motor are activated, and an opposite potential is generated in the motor. When a certain speed is reached, the opposite potential generates a weak current. The start and protection circuit is activated to allow the relay to pass and the current of the battery to rotate the motor through the relay. At the same time, the user controls the acceleration and deceleration of the kick board by controlling the magnitude of the current input to the motor by the power switch and the speed control circuit or the brake unit, respectively, and the running speed of the kick board is controlled. When the speed drops below a certain speed, the voltage output from the battery to the motor is greatly reduced.At this time, when the protection circuit corresponding to the voltage that is too low falls below the set voltage value, the relay is opened. When the user stops the kick board by selecting a brake unit as required, or restarts the kick board, the motor stops when no current is passed. In this case, the kick board is pushed again by human power to move the tires, and the motor is similarly rotated to reach a certain speed.該継 collector becomes a closed circuit state Ri, current of the battery is allowed to drive the motor through 該継 collector, a drive control device for a powered scooter to feature that advancing the scooter. According to a second aspect of the present invention, an overvoltage protection circuit is provided between the relay of the drive control device and the motor. The drive control device for a powered kick board according to claim 1, wherein the circuit is in an open circuit state to ensure safety of the motor and the drive control device. According to a third aspect of the present invention, a separate charger is provided for the battery to perform charging. A current protector is further provided between the charger and the battery, and the charger charges the battery. Claim 1 characterized in that when both currents exceed a certain value, the overvoltage protection tree automatically shuts out the circuit to ensure the safety of the drive control device and the motor. Or a drive control device for a powered kick board according to 2. Therefore, the operation of the invention according to claims 1 to 3 is based on the premise that a drive control device including at least a relay, a starting and protection circuit, a protection circuit for a voltage that is too low, a power switch and a speed control circuit, and a brake unit; It is composed of a battery and a motor, but one end of the relay is connected to the battery, and when the power switch and the speed control circuit are activated, the relay is put into a circuit state. By moving the tire, the motor is rotated, and the coil and the armature inside the motor are activated to generate an electric potential in the opposite direction to the motor. Then, when a certain speed is reached, the potential in the opposite direction emits a weak current to activate the start-up and protection circuit, the relay passes, and the current of the battery rotates the motor through the relay. At the same time, the user controls the magnitude of the current input to the motor with the power switch and the speed control circuit or the brake unit, respectively, thereby controlling the acceleration and deceleration of the kick board, thereby reducing the running speed of the kick board. When the speed drops below a certain speed, the battery greatly reduces the voltage output to the motor. At this time, if the protection circuit corresponding to the voltage that is too low takes the value of the set voltage, the relay enters an open circuit state, and the motor stops, that is, no current flows. Further, at this time, when the user wants to stop the kick board by selecting the brake unit as necessary, or to restart the kick board, the kick board is manually pushed again to move the tires, and the motor is similarly rotated. By reaching a certain speed, the relays pass through and the current of the battery drives the motor through the relays to advance the kickboard.

One end is connected to the battery 1. When the power switch and the speed control circuit 24 are activated, the relay 21 is in an open circuit state, and the user manually moves the tire 41 of the kick board 4 to move the motor 3 To rotate. The coil and the armature inside the motor 3 are driven, and the electric potential in the opposite direction acts on the motor 3. When the motor 3 reaches a certain speed, the electric potential in the opposite direction and its weak current activate the start-up and protection circuit 22. Then, the electric current of the battery 1 passes directly through the relay 21 and the motor 3 is directly rotated by the relay 21, and at the same time, the user uses the power switch and the speed control circuit 24 and the brake unit 25, respectively. The magnitude of the current is input to the motor 3 to accelerate or decelerate the kick board 4.

When the speed of the kick board 4 is lower than a certain speed, the voltage output from the battery 1 to the motor 3 is significantly reduced. At this time, after the protection circuit 23 of the voltage which is too low takes the numerical value, the relay 21 is in an open circuit state, the motor 3 runs out of current and stops, and the user selects the brake unit 25 and If it is desired to stop or restart the board 4, the motor 3 is moved by manually moving the tires 41 of the kick board 4 again, and when the speed reaches a certain speed as described above, the board 4 is restarted. The relay 21 communicates, and the electric current of the battery 1 moves the motor 3 through the relay 21 to move the kick board 4 forward.

By inputting the voltage and the voltage to the voltage input terminal, Q1 is passed and the relay 21 is passed, and the current of the battery 1 drives the motor 3 directly through the relay 21. At the same time, the user operates the power switch. And the speed control circuit 24 and the brake unit 25 are selected to accelerate and decelerate the speed. When the speed is lower than a certain speed, the voltage at which the battery 1 outputs to the motor 3 is greatly reduced, and the voltage of the voltage is reduced by using the protection circuit 23 of too low a voltage constituted by Q1 and Q2. After that, the relay 21 is in an open circuit state, is stopped because no current is flowing, and the kick board 4 is stopped by the user selecting the brake unit 25 as necessary. Alternatively, in the case of restarting, the tire 41 of the kick board 4 is pushed and moved by human power as described above, and the motor 3 is driven until reaching a certain speed to communicate with the relay 21.

An overvoltage protection circuit 26 composed of C4 and R9 is provided between the relay 21 and the motor 3 to determine whether the motor 3 has exceeded a certain load and to determine whether the motor 3 has exceeded a certain load. 21 is opened to protect the motor 3 and the drive control device 2.
