Description

A BICYCLE MOUNTED WITH ANTITHEFT DEVICE}

The present invention relates to a bicycle equipped with an anti-theft device, and more particularly, to a bicycle equipped with an anti-theft device that automatically detects a theft situation and sounds an alarm, activates an additional lock device, To a bicycle equipped with the apparatus.

There are a growing number of users who use bicycles as an environmentally friendly means of transportation.

In recent years, bicycles have also been used frequently in high-priced bicycles that are light in weight and have excellent performance, and bicycle theft is frequently occurring.

Bicycle users may ride bicycles and keep their bicycles on the road to go to places such as restaurants, convenience stores, or toilets.

In this case, the user was not expected to take a long time, and the bicycle was often stolen because he did not lock the bicycle firmly.

Also, there are many situations in which a parked bicycle is stolen, even if it is not the case as described above, and it is very difficult to find a bicycle that has been stolen unless the bike is stolen.

Generally, locks are used to keep the bicycle from being stolen when the bicycle is stored. Typical locks are a bicycle frame, a wheel, or a structure such as a pillar of a bicycle, a bicycle frame, a wire lock, And fixing it.

However, even if the bicycle is locked by such a wire-type locking device, the thief is easily cut off by using a professional cutting tool and theft can not be avoided.

Therefore, there is a need for an active method to break the will of theft from the thief in the field more effectively.

4 (a) and 4 (b) are partial perspective views showing an operation example of the second lock unit of the anti-theft device according to the present invention.

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

1, the anti-theft device T according to the present invention is installed in a seat stay 920 in which a rear wheel shaft 910 of a bicycle 1000 is rotatably connected.

The seat stay 920 is branched on both sides of the rear wheel 930 and the anti-theft device T is installed on the seat stay 920.

Specifically, as shown in FIGS. 2 and 3, the anti-theft device T includes a case 100 fixed to the seat stay 920, a first locking unit 100 installed outside the case 100, A tilt sensor 300 installed in the case 100, an alarm unit 400 for emitting an alarm sound, and an alarm unit 400 receiving signals from the tilt sensor 300 to control the operation of the alarm unit 400 And a control unit 500.

The case 100 is divided on both sides and a groove 110 corresponding to the outer surface of the seat stay 920 is formed on the opposite inner side surface. It is preferable that they are mutually fixed.

In addition, it is preferable that various sensors, a Bluetooth module 700 and a control unit 500, which will be described later, are installed only in the case 100 around the groove 110, thereby preventing power supply and data connection lines from being complicated.

The first locking unit 200 is installed on one side of the case 100 across the rear wheel 930 and is easily wound and fixed on the rear wheel 930.

The first locking unit 200 is constituted by a multi-pipe locking device and is easily folded and stored.

Of course, although the first locking unit 200 may be made of a wire type, it is difficult to keep the first locking unit 200 when it is not locked.

The tilt sensor 300 may include a gyro sensor and an acceleration sensor.

The angular velocity is sensed by the gyro sensor, and an acceleration sensor detects vibration or the like due to a blow of a cutting tool or the like, or can detect whether the bicycle is moving.

If the angular velocity or acceleration sensed by the tilt sensor 300 exceeds a predetermined value, the alarm unit 400 may operate to generate an alarm sound.

The alarm sound may be a simple sound having no meaning or a pre-recorded sound for notifying a warning message.

In order to enable such an operation, a control unit 500 is mounted in the case 100.

That is, when the physical quantity such as the angular velocity or the acceleration sensed by the tilt sensor 300 is transmitted to the controller 500 as a signal, the controller 500 compares the set value with the sensed value, .

Meanwhile, a second lock unit 600 may be installed in the case 100.

The second lock unit 600 functions as an auxiliary lock unit for the first lock unit 200 and is configured to be operated when the first lock unit 200 is broken or when theft is detected.

Specifically, the second lock unit 600 includes a driving unit 610 including a motor and a ratchet unit 620 rotated by the driving unit 610, so that the controller 500 controls the first When the lock unit 200 is damaged or a signal for detecting theft from the tilt sensor 300 is received, the control unit 500 transmits a signal to the driving unit 610 to operate the driving unit 610, (620) is rotated in a direction across the spokes (940) to prevent rotation of the rear wheels (930).

It is preferable that the driving unit 610 and the latch unit 620 are decelerated through the worm and worm gear so that the latch unit 620 is not restored to its original position by simply restoring the latch unit 620. [

In order to detect breakage of the first lock unit 200, the first lock unit 200 is made of a conductive material. When the first lock unit 200 is locked, Can be configured to be blocked.

Alternatively, a separate power connection line (not shown) may be built in the first lock unit 200 to allow the control unit 500 to transmit a signal to the alert unit 400 or a smart phone have.

Meanwhile, the case 100 may be provided with a proximity sensor 750.

The proximity sensor 750 is for detecting a human body and may be connected to the controller 500 to transmit a control signal to the alarm unit 400 or the second lock unit 600 or a Bluetooth module 700 described later.

Specifically, it is preferable that the proximity sensor 750 recognizes an object within a predetermined angle and distance, and is directed toward an upper portion slightly deviated from the bicycle.

This is to prevent the bike itself from being detected by the proximity sensor 750 and to sense the surroundings while the thief is stopped around the bicycle for a while.

For example, when the human body is continuously sensed for a predetermined period of time such as 10 seconds by the proximity sensor 750, a signal is transmitted to the alarm unit 400 by the control unit 500 to generate an alarm sound to warn the thief, As shown in Fig.

Furthermore, it is preferable that a medium-range communication module such as the Bluetooth module 700 is installed in the case 100 so that communication can be performed in a range of 10 m to 50 m.

The Bluetooth module 700 is connected to the controller 500 and detects whether the tilt sensor 300 and the proximity sensor 750 or the first locking unit 200 are disconnected from the Bluetooth module 700 To a portable terminal such as a smart phone (P).

For example, when the human body is continuously sensed by the proximity sensor 750 for a predetermined time, an alarm sound is generated by the alarm unit 400 but no signal is transmitted to the smartphone P, Or if theft is detected by breakage of the first lock unit 200 or the like, a signal is transmitted to the smartphone P so that quick countermeasures can be made.

That is, a situation in which theft is likely to occur and a situation in which actual theft occurs are separated and corresponded, thereby enabling more effective coping.

Of course, the smartphone P may be equipped with an application for receiving the current status of the bicycle.

Generally, since the bicycle is not always used, it is troublesome to replace the battery when the battery is powered, and it is difficult to predict when the battery will be discharged.

Therefore, it is preferable that the power generator 800 is installed in the case 100 so that a separate battery is omitted.

According to the present invention, the power generation apparatus 800 includes a power generation module 810 fixed to the inside of the case 100 and a power generation module 810 connected to the power generation module 810 in a freely rotatable manner, And a power generation wheel 820 protruding from the rear wheel 930 and contacting the rear wheel 930.

The power generation module 810 may include a rechargeable battery.
