The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for the sake of brevity.

1 to 7, a bicycle locking apparatus 100 according to an embodiment of the present invention includes a position changing unit 1, a driving unit 2, a locking unit 3, a restoring unit 4, An alarm unit 5, a sensing unit 21, a control unit 6, and a battery unit 8.

The position changing section 1 rotates the driving section 2 and includes a mounting section 11 and a position changing unit 12. [

The mounting portion 11 is for fixing the position changing unit 12 to the bicycle frame 203 and uses a known "U" type bracket whose one end is detachable from the position changing unit 12, The position conversion unit 12 is connected or disconnected. The mounting portion 11 is disengaged from the position changing unit 12 and the mounting portion 11 in a state where the bicycle frame 203 is disposed between the position changing unit 12 and the mounting portion 11, The position changing unit 12 can be firmly fixed to the bicycle frame 203. [0050]

Here, the mounting portion 11 may be a bracket and a hexagonal wrench bolt which are openly used.

The position conversion unit 12 rotates the drive unit 2 and includes a plurality of gears (not shown) rotated by an electric motor (not shown) and an electric motor, And a keyhole 122 in which a lock key is inserted into the outer surface is formed.

At this time, the position conversion unit 12 is fixed to the bicycle frame 203 by the mounting portion 11, and the rotation axis 121 of the position conversion unit 12 is disposed in parallel with the rotation axis 121 of the bicycle wheel 201 . A detailed description thereof will be described later.

The technique for fixing and releasing the bracket with the lock key described above and the electric motor and the gear using the well-known technique are not described in detail.

The drive unit 2 includes a plurality of gears (not shown) that are rotated by an electric motor (not shown) and an electric motor, and a drive shaft 22 connected to the gears Protrudes outward but protrudes in a direction perpendicular to the rotation axis 121 of the position conversion unit 12 and is connected to the rotation axis 121 of the position conversion unit 12 to be constrained.

Accordingly, when the position conversion unit 12 is operated, the entire driving unit 2 is rotated in any one of forward, backward, upward, and downward directions. When the driving unit 2 is operated, the driving shaft 22 is moved leftward or rightward Rotate.

Here, the known techniques are used for the electric motor and the gear, and a detailed description thereof will be omitted.

The lock portion 3 is inserted between the spokes 202 of the bicycle 200 and is formed in a substantially round or stick shape with one end connected to the drive shaft 22 and the pin 32, So that the inclined surface 31 is formed.

At this time, the lock portion 3 is substantially perpendicular to the drive shaft 22, and when the drive shaft 22 rotates, the lock portion 3 rotates together. Thus, when the driving shaft 22 rotates in the direction of the bicycle spindle 202, the other end of the locking portion 3 is inserted between the bicycle spokes 202 as the locking portion 3 rotates. Thus, the bicycle 200 can be prevented from being stolen by restricting the bicycle wheel 201 by hooking the bicycle spokes 202 to the locking portion 3. [

Here, the lock portion 3 can rotate within the set angle range from the drive shaft 22. That is, when the lock portion 3 is inserted between the bicycle spokes 202, the other end of the lock portion 3 can be brought into close contact with any one of the bicycle spokes 202. At this time, The inclined surface 31 of the lock portion 3 is inserted between the spokes 202 such that the inclined surface 31 slides on the spokes 202. [ Therefore, it is possible to prevent interference between the lock portion 3 and the bicycle spokes 202, thereby preventing the bicycle spokes 202 from being damaged. Even if the lock portion 3 is in close contact with the bicycle spokes 202, 202 of the bicycle sprockets 202. In this way,

The gears described above may be formed of a worm (not shown) and a worm gear (not shown) to prevent the drive unit 2 and the lock unit 3 from forcibly rotating.

The restoring portion 4 restores the locking portion 3, and a return spring, leaf spring, permanent magnet, rubber, or the like is used. In the present invention, two return springs are used. At this time, the two return springs are fitted to the pins 32 and installed.

Accordingly, the lock portion 3 can be positioned at the center within the set angle range at normal times, and is restored to the center once the binding force is removed after being rotated in either direction.

More specifically, when the lock portion 3 is caught by the bicycle spokes 202, the lock portion 3 rotates to either side of the bicycle spokes 202 to enter between the bicycle spokes 202, The locking portion 3 is restored to its original position by the restoring portion 4 when the locking portion 3 is released from the bicycle spokes 202. [

Therefore, the lock portion 3 is always disposed at the center within the set angle range by the restoring portion 4, so that the lock portion 3 can be rotated either side with respect to the center. This can minimize the interference between the lock portion 3 and the bicycle spokes 202 by means of which the lock portion 3 can be inserted either side of the bicycle spokes 202, Can be prevented.

In particular, the lock portion 3 can easily enter the bicycle spokes 202 without changing the position of the lock portion 3. [ In this case, the position conversion unit 1 may be omitted and the driving unit 2 may be directly fixed to the bicycle frame 203. [

[

Accordingly, when the bicycle 200 is held in the locked state, the bicycle 200 is lifted or the locking portion 3 is forcibly rotated or the bicycle 200 is detached from the bicycle 200, And outputting an alarm sound to the outside, thereby preventing a theft accident.

Here, the alarm unit 5 uses a well-known technique, and a detailed description thereof will be omitted.

The sensing portion 21 is built in the driving portion 2 to prevent the locking portion 3 from rotating and catching on the bicycle spokes 202. [

The driving unit 2 receives the information detected by the sensing unit 21 and drives the driving unit 2 so that the driving unit 2 rotates the locking unit 3. [ The locking portion 3 may be reversed to return to its original position.

Thus, it is possible to prevent the bicycle spokes 202 from being damaged or the driver 2 from being overloaded.

The control unit 6 controls the position conversion unit 1 and the driving unit 2 or further controls the alarm unit 5 to control the position conversion unit 1, the driving unit 2, or the bicycle 200 It is installed in one part. Thus, the control section 6 controls the position changing section 1 to prevent the drive section 2 from rotating excessively and to prevent the lock section 3 from rotating excessively by controlling the drive section 2 . Further, by controlling the alarm unit 5, the output time of the alarm sound can be adjusted.

Here, the control unit 6 may receive the information sensed by the sensing unit 21 and change the position of the locking unit 3.

For example, when the lock portion 3 is caught by the bicycle spokes 202 and is no longer movable, the control portion 6 receives information from the sensing portion 21, determines the received information, and operates the driving portion 2 Thereby moving the lock portion 3 in place.

When the locking part 3 moves to the home position, the control part 6 operates the position changing part 1 to rotate the driving part 2 by a set angle to change the position of the locking part 3. [ Thus, by changing the position of the lock portion 3, it is possible to prevent the lock portion 3 from being caught by the bicycle spokes 202 when the lock portion 3 rotates.

Here, the present invention may further include a battery unit 8.
