Friction control mechanism for portable bicycle electric kit using wire {FRICTION CONTROL DEVICE FOR PORTABLE BICYCLE ELECTRIC KIT USING WIRE}

The present invention relates to a friction control mechanism for a portable bicycle transmission kit using a wire. More specifically, it is possible to provide a friction control mechanism for a portable bicycle transmission kit using a wire capable of simple and efficient friction control.

In general, a bicycle is a means of transportation that moves by rotating the wheels using human power and is widely used for transportation, exercise, and leisure purposes. In particular, recently, as bicycle activation policies have been promoted nationally as part of a policy to reduce carbon emissions, the main cause of air pollution, the amount of bicycle use is increasing.

These bicycles are driven using the user's pedaling power, so there is no great difficulty in short distances or on flat ground, but when riding long distances or uphill roads, strong physical strength and large leg strength are required, causing great fatigue to the user. And, depending on the user, this may be a factor in avoiding bicycle use.

To solve these shortcomings, electric bicycles have recently been developed that make riding easier by adding the driving force of the drive motor to the user's leg effort. In other words, the electric bicycle allows the user to operate the drive motor as needed so that the bicycle can be driven with little or no force from the user.

However, since electric bicycles are more expensive than general manual bicycles, purchasing an electric bicycle places a great burden on the user from an economic perspective, and if a user who owns an existing manual bicycle wants to use an electric bicycle, he or she must purchase an additional electric bicycle. Because you have to do it, you may feel a greater burden from an economic perspective.

Specifically, the bicycle electric power kit in Patent No. 10-1127513 includes a drive motor that generates driving force and a drive roller rotated by the drive motor, and is attached to a manual bicycle so that the drive roller contacts the rear tire of the manual bicycle. It is disclosed that when the drive motor is rotated by being installed, the rear tire is rotated by the drive roller to enable driving by the drive motor. This is achieved by installing a bicycle electric kit on a conventional manual bicycle without modifying the manual bicycle. It has the advantage of being able to convert a manual bicycle into an electric bicycle.

However, in the electric bicycle kit according to the prior art, the contact between the drive motor and the tire of the bicycle continues, and even if the user wants to use the bicycle manually, the contact force between the drive motor and the tire is maintained, causing resistance to pedaling, and the electric bicycle There was a problem with the kit being worn or damaged.

The friction control mechanism 100 for a portable bicycle electric kit using a wire according to an embodiment of the present invention is installed on the frame 105 of the bicycle, and the user adjusts the control lever 132 to which the wire 131 is connected. The contact friction force between the friction control mechanism 100 and the bicycle wheel 101 can be controlled.

More specifically, the friction control mechanism 100 for a portable bicycle electric kit using a wire according to an embodiment of the present invention includes an electric kit 110, a fixed and rotating part 120, and a contact force control part 130. .

The electric kit 110 transmits driving force to the bicycle wheel 101 through the motor wheel 111 in contact with the bicycle wheel 101, or generates friction between the motor wheel 111 and the bicycle wheel 101. can be controlled.

The fixed and rotating part 120 allows the electric kit 110 to be fixed and rotated to the frame 105 of the bicycle. More specifically, the fixed and rotating part 120 includes a frame fixing part 121 and an extension part ( 122) and a rotating portion 123.

At this time, the frame fixing part 121 is fixed to the frame 105 of the bicycle, the extension part 122 extends toward the bicycle wheel 101, and the rotating part 123 is the extension part ( It is formed at the end of 123 so that the electric kit 110 can be fixed and rotated.

Additionally, the electric kit 110 may be configured to include a body portion 112 and a rotational coupling portion 113.

More specifically, the body portion 112 is fixed to the motor wheel 111, and the rotational coupling portion 113 extends from the electric kit body portion 112 and is coupled to the rotating portion 123 to connect the wire. The rotational coupling portion 113 is rotated from the rotational portion 123 by the tensile force applied to (131).

The contact force control unit 130 controls the rotation angle of the electric kit 110 rotating on the fixed rotating part 120, and adjusts the contact force of the motor wheel 111 in contact with the bicycle wheel 101. do.

More specifically, the contact force control unit 130 may be configured to include a wire 131 connected to the electric kit 110 and an adjustment lever 132 for tensioning the wire 131.

That is, when the user adjusts the control lever 132 to which the wire 131 is connected, the wire 131 is tensioned and the contact force of the motor wheel 111 in contact with the bicycle wheel 101 can be adjusted step by step. You can. 2 and 3, the more the user pulls the wire 131, the greater the contact force of the motor wheel 111 in contact with the bicycle wheel 101, and the more the user relaxes the wire 131, the greater the bicycle wheel 101. The contact force of the motor wheel 111 in contact with decreases. In addition, according to another embodiment of the present invention, the more the user pulls the wire 131, the smaller the contact force of the motor wheel 111 in contact with the bicycle wheel 101, and the more the user relaxes the wire 131, the bicycle wheel ( It may be configured to increase the contact force of the motor wheel 111 in contact with 101).

For example, if the user adjusts the control lever 132 to loosen the wire 131 as much as possible as shown in FIG. 2, the motor wheel 111 does not contact the bicycle wheel 101. In this state, there is no friction between the motor wheel 111 and the bicycle wheel 101, so power is not transmitted, and there is no resistance applied to the bicycle wheel 101 by the motor wheel 111.

Additionally, the user may adjust the control lever 132 to tension the wire 131 as shown in FIG. 3 so that the motor wheel 111 is in weak contact with the bicycle wheel 101. This state prevents the bicycle wheel 101 from being worn by unnecessarily strong contact with the motor wheel 111 when the bicycle is on a flat surface, and also reduces the contact force between the motor wheel 111 and the bicycle wheel 101. By keeping low, sufficient driving force can be delivered.

Additionally, the user may adjust the control lever 132 to tension the wire 131 as shown in FIG. 4 so that the motor wheel 111 is in strong contact with the bicycle wheel 101. In this state, when the bicycle climbs an incline, the contact force between the motor wheel 111 and the bicycle wheel 101 is maintained high, allowing higher driving force to be transmitted.

As such, according to the present invention, the user can step-by-step adjust the contact force of the motor wheel in contact with the bicycle wheel through the control lever to provide optimal driving force and contact force depending on the presence or strength of necessary driving force.

Therefore, according to the present invention, it is possible to improve the complex and inefficient friction control device of the bicycle electric power kit of the prior art and provide a friction control mechanism for a portable bicycle electric power kit capable of simpler and more efficient friction control.

More specifically, according to the present invention, the problem of resistance to pedaling is solved by maintaining the contact force between the bicycle wheel and the motor wheel in situations where the assistance of the electric kit is unnecessary or the electric kit does not operate, and there is no need for an electric kit that is not driven. It can prevent wear or damage from contact with the wheel.

In the detailed description of the present invention as described above, specific embodiments have been described. However, various modifications are possible without departing from the scope of the present invention.
