First, the combined electric motors 20 and 20 'of the 2009 patent application No. 035298 issued by the applicant of the present invention, the rotary plate 110 and the magnet body attached to the magnet body 111, 111' radially Coil bodies 121 and 121 'corresponding to (111) and 111' are formed of fixed plates 120 and 120 'formed by radially horizontal winding. The fixing plates 120 and 120' It is formed spaced apart from both sides of the rotating plate 110, the rotating shaft 21 in the center of the rotating plate 110 is coupled by a bearing from the fixing plate 120, 120 'is to be free to rotate.

Accordingly, when the rotating plate 110 rotates from the external power, the sign of the electric charge is applied to the coil bodies 121 and 121 'by the magnet bodies 111 and 111', and is applied as described above. Through the sign of the charge, the power generated from the coil bodies 121 and 121 ′ can be used as a generator capable of charging the battery through the transformer transformer and the rectifying element.

In addition, when an external power source is applied to the coil bodies 121 and 121 ', the sign of the electric charge generated from the coil bodies 121 and 121' is applied to the magnet bodies 111 and 111 'of the rotating plate 110. Since the attraction and repulsive force are generated by interference with the polarity, it is possible to use the electric motor to continuously rotate the rotating plate 110 through the alternate switching supply of the external power.

The combined power generation motors 20 and 20 'are fixed to both sides of the board body 10 in the form of a flat plate, and the rotary shaft is located at the center of the combined power generation motors 20 and 20'. Separate driving wheels 22 and 22 'are coupled to the 21, and the driving wheels 22 and 22' may be directly connected and fixed to the rotating shaft 21, and appropriate power and In order to obtain the rotation ratio, the small gear coupled to the rotating shaft 21 and the coupling gear between the air gear coupled to the driving wheels 22 and 22 'may be connected to each other.

In addition, as shown in the lower side of the board body 10, the auxiliary wheels 11 and 11 'are respectively coupled to the front and rear sides, so that the board body 10 is operated by receiving power. It has a four-sided support structure by the auxiliary wheels (11) (11 ') for providing a balance of the driving wheels 22, 22' and the board body (10).

In particular, the combined power generation motor 20, 20 'as described above is electrically connected to the battery 40 and the control box 50 mounted on a separate waist belt 30 made to be worn on the user's waist. Is made, the control box 50 is to be connected to a separate controller 60 made to be operated by the user directly holding the hand.

Accordingly, the user puts one foot on the board body 10 in a state where each of them is separately produced, and then operates the controller 60 to generate power through the control box 50 from the battery 40 in the charged state. As power is supplied to the combined electric motors 20 and 20 ', the driving wheels 22 and 22' which receive the rotational force while operating the combined electric motors 20 and 20 'are rotated while the electric motor of the present invention is rotated. It will provide electric propulsion to the skateboard.

In addition, when the electric skateboard is going downhill or the driving force generated by the attraction force is to operate the controller 60 to supply the power of the battery 40 to the combined electric motor 20, 20 '. By the charging of the battery 40 due to the sign of the charge obtained from the non-generation combined electric motors 20 and 20 ', the user is in the electric skateboard of the present invention in various environments, such as downhill or flat or uphill It can be driven automatically or charged on its own, enabling continuous and long-range use.

The control box 50 and the controller 60 as described above are described in detail by Patent Registration No. 0928433 registered by the applicant of the present invention, which will be outlined as shown in FIG.

That is, in the state where the battery 40 is sufficiently charged, the changeover switch 61 mounted on the controller 60 is operated so that the power of the battery 40 is supplied to the coil body 121 of the fixing plates 120, 120 ′. When applied to (121 '), the rotating plate 110 by the attraction force and repulsive force acting in the polarity between the sign of the charge acting on the coil body 121, 121' and the magnet body 111 (111 '). ) Is forcibly rotated.

At this time, the power of the battery 40 is repeatedly provided by switching the polarity by the polarity switching unit 53, the rotating plate 110 has a continuous rotational force. In addition, the polarity switching unit 53 is a phase sensor 54 for detecting the phase of the magnet body 111 (111 ') and the phase sending unit 55 for transmitting the detection signal of the phase sensor 54 and As it is connected, as the magnet bodies 111 and 111 'of the rotating plate 110 begin to rotate, the polarity of the power source provided from the battery 40 in accordance with the phases of the magnet bodies 111 and 111' is continuously applied. Since the rotating plate 110 is supplied to the unit 121 and 121 ′, the rotating plate 110 performs a continuous rotation by the attraction force and the repulsive force acting on the magnet bodies 111 and 111 ′.

Particularly, the coil bodies 121 and 121 'disposed radially on the fixed plates 120 and 120' are selectively supplied with power by a separate unit speed variable 56, and thus unit speed The rotational speed and rotation with respect to the rotating plate 110 by supplying a form of power applied to the coil bodies 121 and 121 'through the variable part 56, that is, supplying individual or group (group) forms. The torque can be adjusted.

The unit speed variable part 56 may be made through a shift switch (not shown in the drawing) mounted on the controller 60, and each coil body 121 and 121 may be operated each time the shift switch is operated as described above. By changing the supply form of the power applied to ') is to increase or decrease the rotational speed and rotational force of the rotating plate 110.

Therefore, as the rotary plate 110 is rotated by using the battery 40 as described above, the driving wheels 22 and 22 'rotate together with the battery 40, so in the case of the uphill or flat, the combined electric motor 20 ( 20 ') actuated to serve as an electric motor would enable the use of convenient electric skateboards.

On the other hand, when driving downhill or flat driving, the user may be able to charge the battery 40 as needed. In the case of downhill driving, the weight of the user and the own weight of the electric skateboard may be driven. In this case, by operating the switch 61 mounted on the controller 60, the combined electric motors 20 and 20 'may serve as a generator.

That is, the magnet body 111 (111 ') of the rotating plate 10 is converted to a function as a generator as described above, when the rotational force of the driving wheels 22, 22' is transmitted to the forced rotational force of the rotating plate 110 It will affect the coil bodies 121 and 121 'of the fixed plates 120 and 120' and cause the sign of charge to be generated, and the charge generated from the coil bodies 121 and 121 'as described above will be transformed transformer 51 It will be purified through), and reaches the rectifier element 52 serves to convert the AC power source to DC power source to automatically charge the battery 40.

In particular, the combined electric motor 20, 20 ′ as described above is provided between the magnet body 111, 111 ′ of the rotating plate 110 and the coil bodies 121, 121 ′ of the fixed plate 120, 120 ′. Since it rotates in a free-running manner that does not occur at all in the interference resistance, the driving force of the electric skateboard does not interfere with the above-described power generation.

As described above, the electric skateboard of the present invention enables selective operation of an electric motor or a generator in a terrain such as an uphill or downhill, and enables long-term and long-distance use through convenient charging as well as continuous use.

In addition, the board body 10 as described above is composed of two divided objects to each have the same configuration, each one of the board body 10 to put one foot of the user, respectively, to have more freedom for both feet Configured to be used in one state, or as shown in Figure 7 consists of a board body 10 as a single rectangular object to put both feet of the user on the board body 10 at the same time as a conventional skateboard It may be possible.

In particular, in some cases, the auxiliary wheels 11, 11 'and the driving wheels 22, 22' may have a straight arrangement, such as in-line skates, and may be used. (11) (11 ') can also manufacture and produce electric skateboards of more diverse structures by adopting only one or not applying them so that they can be used centering only on the driving wheels 22 and 22'. .
