Folding Electric Kick Board {Folding Electric Kick Board}

The present invention relates to a foldable electric kickboard, and more particularly, to a foldable electric keyboard that provides convenience in operation by a simple folding structure and at the same time minimizes the volume when folded and stored to provide convenience such as transport or storage. it's about

An electric kickboard or a similar type of electric driving device is in the spotlight as a simple means of transportation or a means of leisure. These electric kickboards are equipped with a rechargeable battery, so they can be charged and used.

They also use public transport. There are various types of electric kickboards, and there is a type consisting of a footrest and a handle extending at a right angle and similar to the footrest. These handles are equipped with a control switch and have more stability than those without a handle.

However, an electric quick board with a handle is more bulky than one without. Therefore, it is inconvenient to ride a bus or subway with an electric kickboard. The kickboard has a folding kickboard with a handle that can be folded as shown in Korean Utility Model Registration Application No. 20-2000-0029093.

The folding kickboard of the Republic of Korea Utility Model Registration Application No. 20-2000-0029093 is provided with front and rear wheels, and the rotating shaft and the support shaft are integrally folded with respect to the scaffolding. and a plate body erected orthogonally to one side end of the horizontal plate, two locking grooves of the same size are formed at regular intervals, while a right side plate in which a rotation shaft hole is formed at the lower end of the horizontal plate; , This is a plate body erected on one side end of the horizontal plate to face the same shape as the right side plate, and two seating holes corresponding to the locking holes are formed, while an arc-shaped guide hole for connecting the seating holes is provided. a folding guide formed as a left side plate formed with a rotation shaft hole corresponding to the rotation shaft hole; a supporter having one end fixed to the support shaft, the other end being sandwiched between the side plates and axially installed by a rotating shaft, each of which has folding pinholes formed in the middle portions of both side plates; and a locking hole of the right side plate, a folding pin hole of the supporter, and a seating hole of the left side plate, while being installed, a coil spring is located on the outer surface thereof, and one end of the folding pin handle is located on the left side plate A folding device for a kickboard is provided, which is fixed and includes a folding pin that is formed while the other end has a diameter smaller than that of the locking groove.

In addition, the foldable kickboard disclosed in Korean Patent Application No. 10-2011-0113432 includes a handle support frame provided to be rotatable left and right to adjust the direction of a steering wheel installed at the lower end using a steering handle provided at the upper end; a footrest provided at the rear of the handle support frame so as to be horizontal with the ground, the fixed frame is extended at the front end and the rolling wheel is installed at the rear end; and a first folding frame having one end rotatably connected to the fixed frame and the other end rotatably connected to the handle support frame.

As described above, although a folding kickboard has been proposed in the prior art, in most cases, it is necessary to use a hand when folding or unfolding it, or the folding structure is too cumbersome. In recent years, aesthetic factors have also become a very important factor in determining the purchase intention of a product. Also, simply folding the handle is not preferred because there is a limit to reducing the volume of the kickboard.

And in the case of an electric kickboard, the driving part is installed on the rear wheel, and the driving part is installed on one handle, that is, the ignition key for turning the driving motor on/off, the accelerator for adjusting the speed, and the adjusting part for controlling the brake operation, etc. are installed on one handle, and the adjustment part It has a structure that can transmit a signal by connecting the and the driver with a cable.

As such, when the cable is present, there is a limitation in reducing the volume of disassembling and folding the kickboard, and there is a problem in that there are many restrictions in reassembly.

Republic of Korea Utility Model Registration Application No. 20-2000-0029093 and See Korean Patent Application No. 10-2011-0113432.

In response to the above problems, the present invention aims to provide a foldable electric kickboard that enables both the handle and the footboard to be folded or unfolded in a folding operation to minimize the volume of the electric kickboard, thereby promoting convenience of portability and storage. There is this.

Another object of the present invention is to eliminate the cable that transmits the signal of the adjustment unit to the driving unit, so that the folding operation of the handle and the footrest can be performed quickly, and the appearance of the kickboard is made simpler and more beautiful, and the factor of occurrence of a safety accident is reduced. It is to provide a folding electric kickboard that can be removed from the source.

In order to achieve the above object, the present invention provides a footrest for a passenger to ride with his/her feet on it, a steering shaft coupled to the front end of the footrest portion, a handle provided on the upper end of the steering shaft so that the passenger can drive; In the electric kickboard comprising: a driving unit installed on the footboard to transmit rotational force to a driving wheel; and an adjustment unit installed on a handle to control the driving unit, wherein the footrest unit includes a front plate on which the front wheels are installed, and a back plate on which the driving wheels are installed; Formed as an intermediate plate interposed between the and the rear plate, and before and after the intermediate plate, movable plates projecting and protruding into the middle plate are respectively formed, and each movable plate has a coupling portion inserted and coupled to the coupling groove of the front plate and the back plate. It is constructed by forming an elastic coupling protrusion in each coupling part, and a coupling hole is formed in each of the front plate and the back plate to which the elastic coupling protrusion is elastically coupled, and a fixed shaft to which the steering shaft is inserted and fixed on the upper surface of the front plate is provided. It is formed, and the steering shaft and the handle are characterized in that the diameter is sequentially formed and configured to vary in length while protruding and retracting.

The present invention forms a dovetail-shaped defect groove and a protrusion on the sliding surfaces of the handle, the steering shaft, and each footrest, respectively, and forms a conductor surface that transmits an electric signal on the contact surface of the protrusion and the groove to transmit the signal of the adjustment unit to the driving unit. It is characterized by being configured to be able to.

The present invention as described above has the effect of maximizing the convenience of portability and storage by minimizing the volume by folding or unfolding all of the handle, the steering shaft, and the footrest in a folding operation.

In addition, by excluding the cable that transmits the signal from the control unit to the driving unit, the folding operation of the handle and footrest can be made quickly, the exterior of the kickboard is made simpler and more beautiful, and the cable, the cause of safety accidents, can be completely removed. it has an effect.
