The board body 100 may be further provided with a cover for attaching and detaching the control device 200 and a plurality of watertight connection terminals or ports (not shown). For example, the control device 200 may include a central controller 220 that controls the operation of the driving motor 180 or the light 130 in response to an input signal from the sensor unit 210.

As shown in FIG. 3A, the control device 200 includes a sensor unit 210 connected to the central controller 220 through the input/output processing unit 230. The input/output processing unit 230 may be a circuit device that converts an analog signal into a digital signal, and conversely, may serve to output a control signal and an operating power of the central controller 220 toward the sensor unit 210.

The sensor unit 210 may include a tilt sensor electrically connected to the control device 200 so as to measure the reference tilt in the longitudinal direction and the reference tilt in the width direction of the board body 100 shown in FIG. 1 or 2.

The installation position of the sensor unit 210 may be located in the folding unit 120 or may be a sensor installation space provided in the board body 100 connected to the folding unit 120.

The tilt sensor of the sensor unit 210 basically inputs the tilt of the board body 100 to the central controller 220 of the control device 200 to perform the following smart functions.

That is, the central controller 220 of the control device 200 receives the longitudinal tilt angle measurement value of the board body 100 from the tilt sensor of the sensor unit 210 and guides the cruise function to the user.

An external user interface device connected to the central controller 220 as one of a speaker, a display panel, and a touch panel for function guidance may be further installed on the electric kickboard 10 (not shown). That is, user manipulation and function expression related to the electronic control operation described in this embodiment, including the cruise function, may be performed through the user interface device.

For example, the user operates the user interface device to execute a preset cruise program in the memory 240, and the central controller 210 of the control device 200 guides the cruise function to the user, according to the user's speed setting operation The cruise range speed value is set.

The central controller 220 of the control device 200 is proportional to the measured inclination angle through the driving motor driving unit 208 connected to the central controller 220 to correspond to the cruise range speed value set according to the guide. Electronic so that the output amount of the driving motor 180 can be adjusted or the braking amount of the brake 170 is adjusted through the brake driving unit 207 connected to the central controller 220 to maintain the speed in the inclined section during driving. It is constructed in a circuit.

For example, as illustrated in FIG. 5, the output amount of the driving motor 180 in a horizontal plane or a non-inclined section is 1000 rpm in consideration of a load, a user's expected weight, and a design weight of the electric kickboard 10. In this case, the output amount of the driving motor 180 may be 1800 rpm in proportion to the inclination angle measurement value at a relatively high inclination angle R3, and the driving motor 180 may be changed according to changes in the inclination angles R2 and R1. Output can be controlled proportionally to 1600rpm and 1400rpm respectively.

In addition, the sensor unit 210 is further configured to further include an illuminance sensor.

Accordingly, the central controller 220 is a dimming driving unit connected to the central controller 220, so as to adjust the ambient brightness in response to the brightness detection value around the movement path during the night movement received from the illuminance sensor of the sensor unit 210 Also plays a role of controlling the brightness of the light 130 to be brighter by a preset value when the ambient brightness is dark through 203 and darkening the brightness of the light 130 by a preset value when the ambient brightness is bright. can do. Here, the preset value for the light 130 may be an information value that is set through the experiment at the time of manufacture of the control device 200 of the present embodiment for dimming control and is recorded and managed in the memory 240 in advance.

In addition, the sensor unit 210 is connected to the user interface device for on-off operation, or further includes a switch installed on the steering unit 110 independently,

That is, the central controller 220 is configured to control the laser irradiator 140 through the beam driver 204 connected to the central controller 220 in response to the on/off signal of the switch of the sensor unit 210. . As a result, in the laser irradiator 140, the laser light of the mesh pattern or the mesh structure pattern may be irradiated toward the ground relatively far than the irradiation distance of the illumination light of the light 130.

FIG. 4 is a right side view for explaining a method of using a laser irradiator of the electric kickboard shown in FIG. 2.

Referring to FIG. 4, the laser beam L of the mesh pattern or the mesh structure pattern in the laser irradiator 140 during night movement of the electric kickboard 10 may be irradiated about 20 m ahead, and the shape of the front road may be foreign matter or When the protrusion M is convex, or is recessed, the irradiated laser light is bent in an embossed or engraved shape, so that a user or driver can realize safe driving while recognizing the state of the road ahead.

FIG. 5 is a right side view for explaining the kick-and-go function of the electric kickboard shown in FIG. 2.

Referring to Figures 3a and 5, the sensor unit 210, after the electric kickboard 10 is stopped on the ramp, the user performs a kick and go (kick and go) function to start toward the inclined direction, the sensor unit ( 210) may further include an acceleration sensor or a gyro sensor interlocking with the tilt sensor. In addition, the sensor unit 210 may further include a conventional speed sensor for measuring the speed of the electric kickboard (10). In addition, the control device 200 is connected to the central controller 220, may further include a hall sensor and a power management unit 209 for measuring the amount of power of the battery 190. The power management unit 209 is configured electronically to perform a charging function, a discharge alarm function, and a power sharing function. The power management unit 209 may be provided with a charging port 202 to be electrically connected to an external DC charger (not shown) or a connection terminal of a connection frame to be described below.

The central controller 220 checks an operating state or an inclined posture signal of the electric kickboard 10 according to the kick through the tilt sensor and the acceleration sensor or the gyro sensor of the sensor unit 210. Thereafter, the central controller 220 may add or subtract a preset kick range speed value in response to the inclined posture signal. Here, the preset kick range speed value may be recorded in the memory 240. In addition, the central controller 220 may control the driving motor driving unit 208 and the brake driving unit 207 such that the electric kickboard 10 moves at a speed corresponding to the addition or subtraction.

As a result, when kicking when the electric kickboard 10 is started by the user according to safety regulations, the inclination sensor of the sensor unit 210 is used to recognize the uphill or downhill road for each inclination angle R1, R2, R3. , Since it can start at an added or subtracted speed from a preset kick range speed value, by implementing a smooth drive when the user climbs a stop at a road or a ramp having an inclination angle (R1, R2, R3), an easy and smart start There is an advantage that can be performed.

Referring to FIG. 2 or 3A, the control device 200 checks the operating state values of the charge amount of the battery 190 detached from the board body 100, the sensor unit 210, and other components requiring self-diagnosis. The device diagnosis unit 260 may be further included to transmit to the application 21 of the user's smartphone 20 through the short-range communication unit 250.

In addition, the short-range communication unit 250 receives a passage guide beacon signal from a plurality of beacon tags 30 previously installed on a road or a riding path for driving of the electric kickboard 10, and the application 21 of the smartphone 20 ).

Here, the application 21 of the smartphone 20 can be connected by pairing with the short-range communication unit 250 of the electric kickboard 10, and the loss prevention function of the electric kickboard 10 itself, the electric kickboard 10 It can be programmed to perform fault diagnostics, kickboard riders (eg, users) route management and sharing functions.

For example, the anti-lost function is when the Bluetooth module pre-installed on the smartphone 20 and the short-range communication unit 250 of the electric kickboard 10 are farther than a predetermined distance to the application 21, that is, the Bluetooth module and the short-range communication unit. When a value outside the preset distance range is detected centering on the driver based on the measured value of the signal strength measured between the transmission and receiving signals falling below (250), it may mean a function in which an alarm is generated or guided in the application 21.

The application 21 of the smartphone 20 may register identifiers of other users (eg, riding meeting members) riding with the user, respectively. At this time, the beacon tags 30 for location guidance are installed at predetermined locations along the movement path, and smoothly perform relatively high-power communication with the short-range communication unit 250 of the electric kickboard 10. In conjunction with this, the short-range communication unit 250, the application 21 of the smart phone 20 and the Bluetooth module serve to lower the power consumption of the smart phone 20 through mutual low-power communication.

In addition, when a user or a member rides on their own electric kickboard 10, the passing guidance beacon signal (including an identifier) and its reception time (for example, the corresponding beacon tag passing time) are transmitted by the electric kickboard 10 every predetermined period. ), the short-range communication units 250 may be mutually transmitted.

As a result, the location and time information of the electric kickboard 10 passed to each smartphone 20 is collected and shared, so that when the drivers (users) registered to ride together pass, the application 21 transmits the information. Passing guidance Based on the beacon signal, it guides who passed when and when, identifies people who have not yet passed, and then guides other users to enable smooth riding.

The control device 200 uses a large-capacity battery 190 of the electric kickboard 10 for the operation of the short-range communication unit 250, and low power consumption is possible for short-range communication with the smartphone 20. Therefore, the short-range communication unit 250 uses the battery 190 of the electric kickboard 10 with relatively little power usage for communication with the external beacon tag 30, and uses a smartphone through relatively low power consumption. By communicating with (20), there is an advantage that can minimize the power consumption of the smartphone 20 according to the riding of the electric kickboard (10).

FIG. 6 is a rear view of the electric kickboard for explaining the side wheel shown in FIG. 1.

Referring to FIG. 6, when the board body 100 is viewed based on its front or rear direction, a pair of electric side wheels 300 respectively installed on both bottom surfaces or bottom surfaces of the outermost borders of the board body 100 are shown. It may further include. Here, the driving direction of the side wheel 300 may be perpendicular to the driving direction of the rear wheel 160.

That is, each side wheel 300 may be controlled to be rotated by the side wheel motor 310 to drive or rotate in the width direction of the board body 100.

The side wheel motor 310 may be a wheel-integrated device in which the motor rotation axis is matched to the rotation axis of the side wheel 300.

The side wheel motor 310 may be connected to the central controller 220 of the control device 200 through the electric wire, the side wheel motor driving unit 201, and the input/output processing unit 230.

3A and 6, the side wheel motor driving unit 201 of the control device 200 side-sides to the side wheel motor 310 in correspondence with the reference width inclination detected by the tilt sensor of the sensor unit 210. It is responsible for the forward or reverse rotation of 300.

Therefore, when the electric kickboard 10 tries to fall in the lateral direction or the width direction, the tilt sensor or the gyro sensor of the sensor unit 210 detects such a fall. In this case, the central controller 220 calculates a control value sufficient to properly hold the posture according to the falling, and operates the side wheel motor 310 in the opposite direction to the falling direction in response to the calculation result, As a result, while the side wheel 300 is in contact with the ground, the direction of the frictional force according to the rotation of the wheel acts as a balance restoration direction of the electric kickboard 10. As a result, the electric kickboard 10 may be able to recover the balance according to the rotation of the side wheel 300.

In addition, each side wheel 300 is supported to be rotated by the wheel bracket 320. At this time, the wheel bracket 320 is connected to the damper 330 installed inside the bottom surface of the board body 100. Therefore, the side wheel 300 is installed on the basis of the bottom surface of the board body 100 and can be supported by a damper 330 absorbing shock, absorbing shock in the falling situation of the electric kickboard 10 There is an advantage that can increase the durability of the electric kickboard 10 and the side wheel 300.

Referring to FIG. 1, the board body 100 may further include protectors 340 respectively installed on the bottom surface of the board body based on the front position of the side wheel 300. The lower protruding height of the protector 340 has a relatively low wedge shape or triangular block shape than the lower protruding height of the side wheel 300, and may be formed of a durable engineering plastic material or an elastic material. That is, since the protector 340 is a victim installed at the front position of the side wheel 300, the side wheel 300 is safely protected from contact with a road-preventing chin, etc., which is pre-installed on the ground during the progress of the electric kickboard 10.
