Description

Auxiliary power unit for roller skates {POWER ASSISTANCE DEVICE FOR ROLLER SKATE}

The present invention relates to an auxiliary power device for roller skates, and more particularly, to generate electric energy from the rotational force of the wheel, and to store it in a rechargeable battery so that it can be used as an auxiliary power required for the rotation of the roller when necessary, roller skating The present invention relates to an auxiliary power unit for roller skates that can facilitate user convenience.

In recent years, roller skating has been enjoyed by many people as leisure sports. Unlike ice skating, it can be used on general land, and the place of use is usually on a flat terrain. In the case of roller skating, the user advances by reacting with the user's foot against the ground.

However, such roller skates require a lot of power when climbing a ramp or the like. That is, since roller rollers are coupled to each other in a straight line in a straight line, the roller skate receives a force to descend backward, that is, backward by gravity. Therefore, the uphill inclination requires a greater force for the foot, so that the user is easily tired and feels a lot of fatigue, and rather has a problem that results in halving the exercise effect.

In particular, this problem is more likely to occur when using a general road or a long distance roller skating, which is not a suitable place for roller skating.

Accordingly, the present invention has been made in order to improve the above problems, the object of the present invention is to provide a roller skate in the roller skating on the slope, such as to reduce the user's physical consumption, to provide a light roller to enjoy a light exercise.

The object of the present invention is a main frame is fixed to the bottom of the wear portion, in the construction of the roller skates provided with a plurality of rollers on the main frame, the coil 13 at the periphery of the at least one rotation shaft 12 of the roller Winding is generated by a plurality of power generating rollers 10 for generating electric energy by the rotation of the roller, the rechargeable battery is fixed to the upper surface of the frame to charge the electric energy generated by the power generating means, the electric energy supplied from the rechargeable battery, It can be achieved by a drive motor for rotating the drive roller provided at the rear end of the main frame, and the auxiliary power device of the roller skate consisting of a remote switch means for selectively turning on / off the electric energy supplied to the drive motor.

The power of the drive motor is driven by a drive gear connected to the motor shaft, an idle gear rotatably supported by the auxiliary frame extending from the main frame and engaged with the drive gear, and fixed to the drive roller shaft and engaged with the idle gear. Is transmitted through the driven gear.

The remote switching means opens and closes the line between the rechargeable battery and the driving motor according to a remote controller operated by a user and a signal from the remote controller.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 shows the configuration of a preferred embodiment of a roller skate according to the invention.

According to the present invention, the wearing part 1 is fixed to the upper part of the mainframe 14. In the main frame 14, a plurality of power generating rollers 10 and driving rollers 40 are arranged in a row rotatably by shafts 12 and 42, respectively. The power generation roller 10 has a coil 13 wound around the at least one rotation shaft 12 of the roller to generate electrical energy by the rotation of the roller. Configurations related to such power generation are well known configurations, and detailed descriptions thereof will be omitted.

And, the upper side of the main frame 14, the rechargeable battery 20 for charging the electric energy produced by the power generation roller 10 is fixed.

In the rear of the main frame 14 is installed a drive motor 30 is operated by the electric energy supplied from the rechargeable battery (20). The drive motor 30 is fixed to the auxiliary frame 16 extending to the rear of the main frame 14. The drive motor 30 rotates the drive roller 40 which is rotatably fixed to the last end of the main frame 14.

3 shows a connection relationship between the drive motor 30 and the drive roller 40. That is, the driving motor 30 is engaged with the driving gear 34 fixed to the motor shaft 32 and rotatably supported by the idle shaft 50 supported by the auxiliary frame 16. An idle gear 52 is provided. The driving roller shaft 42 is provided with a driven gear 44 engaged with the idle gear 52. Therefore, the rotational force of the drive motor 30 is configured to transmit the deceleration.

On the other hand, the present invention includes a remote switching means 60 for selectively turning on / off the electrical energy supplied to the drive motor (30). 4 is a block diagram schematically showing the operating state of the present invention. The remote switching means 60 is opened and closed by the user and the remote controller 62 to operate as needed, and the line between the rechargeable battery 20 and the drive motor 30 in accordance with the operation signal of the remote controller 62. It consists of a relay 64.

In the present invention having such a configuration, when the user wears the roller skates and the foot is tired, the power generation roller 10 and the driving roller 40 rotate together and move forward. At this time, electricity is generated by the rotation of the power generating roller 10 and stored in the rechargeable battery 20. Meanwhile, the idle gear 52 and the drive gear 34 rotate according to the rotation of the drive roller 40, but at this time, the idle gear 52 and the drive gear 34 achieve idle rotation.

Subsequently, when the user turns on the remote controller 62, the electricity of the rechargeable battery 20 is supplied to the drive motor 34 to rotate the drive motor 30, and this operation is performed by turning the idle gear 52 and the driven gear 44. It is transmitted to the drive roller 40 through. Therefore, the rotational force of the drive motor 30 is added to the force supported by the user foot to reduce the burden on the user. Therefore, the user can selectively operate the remote controller to more easily enjoy roller skating in a state of long-term exercise on an uphill or flat land.

As such, the present invention is not limited to the above-described embodiments, and should be construed to include a range that can be implemented through necessary additions, combinations, changes, and the like within the scope of not changing the gist of the present invention.

That is, the position of the rechargeable battery 20 is not limited to the upper position of the main frame, and can secure a space on the side of the wearing part, but it can be expected that only the electrical connection is different.

In addition, the drive motor and the drive roller can be expected to be compactly integrated by not passing through the idle gear.

That is, Fig. 5 shows another embodiment of the configuration of the drive roller. According to this, the drive motor 70 receives electricity from the rechargeable battery 20 is directly fixed to the frame 14, the motor shaft 72 is fixed to the frame 14, the bearing ( 78) The supported motor housing 74 is configured to rotate. In addition, a drive roller 76 is provided on the outer circumference of the motor housing 74 of the drive motor 70. This drive roller 76 is preferably made of a urethane material excellent in friction and durability. In addition, it is preferable that the width of the driving roller 76 is also wider than that of the power generating roller. To this end, it is required to widen the rear of the frame 14. In this embodiment of the present invention by providing the drive roller 76 directly to the motor housing 74 of the drive motor 70, while simplifying the structure, the present invention can achieve the object as well as reduce the driving force loss. You can expect the effect.

In the roller skate according to the present invention described above, the electric energy generated by the rotational force of the roller is charged to the rechargeable battery, and if necessary, it is supplied to the driving motor to add the rotational force to the roller, thereby reducing the force worn by the user relatively. In particular, by reducing the force pushed backwards on an uphill road, the guidance force can be used to move forward, thereby reducing the user's physical consumption and further providing a comfortable exercise condition.
