DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle locking device, and more particularly, to a bicycle locking device that can be opened and closed remotely.

[0002]

2. Description of the Related Art As is well known, bicycle locking devices include a device in which a key is inserted into a mechanical lock provided on a vehicle body side to slide an iron core, and a device which is engaged with both ends of a chain or a wire. There are locks provided with a lock body, and a rotary ring engraved with the number is rotated to match a preset number to unlock.

[0003] In either system, a rod-like body or a chain is passed between spokes of the wheel to suppress the rotation of the wheel.

[0004]

However, in the above-mentioned conventional device, the lock cannot be unlocked unless the key is inserted into the lock or the number is not matched, so that the locking and unlocking is troublesome, and the bicycle can easily be started. There is a problem that you can not.

Therefore, it is conceivable to apply a wireless remote control key already provided for an automobile.
Smooth operation cannot be expected due to the structure of the bicycle. Because, in general, locks for bicycles have a structure that prevents the rotation of the wheel by inserting a rod-like thing between the spokes of the wheel, so the rod-like thing needs to be inserted at the position where the spokes escaped is there. This escape can be easily obtained by rocking the bicycle back and forth when locking artificially, but if you try to do this remotely, the rod-shaped object and the spoke may hit from the front, and locking may occur .

For this reason, there is a problem in practicality, for example, it is necessary to visually check whether or not the lock has been performed. Also, when the rod hits the spoke front, excessive force acts on both,
It may cause a failure of the lock mechanism and the vehicle body.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a bicycle lock device capable of reliably performing remote control of a lock. Another object of the present invention is to provide an inexpensive bicycle lock device capable of reliably performing remote control of a lock.

SUMMARY OF THE INVENTION The present invention is a bicycle locking device, and is configured as follows to solve the above-mentioned technical problem.

That is, the first invention comprises a lock 3 to be attached to the bicycle body 2 and a transmitter 4 separate from the lock 3, and the lock 3 locks the rotation of the wheels. Arm 5, which is movably provided for this purpose, an actuator 6 that drives the lock arm 5, and a decoder 7 that decodes an operation mode transmitted from the transmitter 4 and drives the actuator 6. An acute angle portion 50 was formed at the tip of the lock arm 5, and the entire lock portion 3 was supported by an elastic mechanism 51.

The acute angle portion 50 is formed by connecting the tip of the lock arm 5 to
It can be formed in a spear shape of a degree. Note that the acute angle portion 50 may have any shape as long as it has a tapered surface that acts so that the lock arm 5 escapes in a direction perpendicular to the spoke when it comes into contact with the spoke. Further, as the elastic mechanism 51, a mechanism in which the lock portion 3 is attached to the bicycle main body 2 via a coil spring, rubber, or the like can be exemplified.

With this configuration, the lock 3 can be opened and closed by operating the transmitter 4. Also, at this time, since the tip of the lock arm 5 is the acute angle portion 50, even when the lock arm 5 comes into contact with the spoke of the wheel, it can escape (move) in any direction. In addition, since the entire lock portion 3 is supported by the elastic mechanism 51, there is more room for escape, and locking by remote control can be performed more reliably.

Further, as a second invention, this device is an electronic control unit 1 for controlling at least one of driving and braking.
Can be attached to the bicycle 2 provided with Specifically, a drive system such as a gear change and a brake braking are electronically performed. For example, a gear is automatically shifted according to a traveling load, and a lock is not performed even when a sudden braking operation is performed. It has a special anti-lock brake function.

The main components are an information processing section 8 mainly composed of a microprocessor, sensors for transmitting various sensing signals to the information processing section 8, and a transmission and the like based on the control contents determined by the information processing section 8. A power control unit for driving is provided. Then, the ROM (READ ONLY MEM)
(ORY) or the like, so that the calculation is performed based on the calculation procedure.

[0014] In addition to these functions, a safety system for detecting approach of an automobile or the like may be provided. A lock 3 to be attached to the bicycle main body 2 as described above, and a transmitter 4 separate from the lock 3 are provided.

The lock portion 3 includes a lock arm 5 movably provided for locking the rotation of the wheel 4, an actuator 6 for driving the lock arm 5, and the transmitter 4.
And a decoder 7 for decoding the operation mode transmitted from the controller 7 and driving the actuator 6. The function of the decoder 7 is included in the operation calculation procedure of the information processing unit 8 provided in the electronic control unit 1. It is.

The lock arm 5 is engaged with a spoke of the wheel 4 like a general lock, and is constituted by an actuator 6 constructed by combining a motor and a speed reducer.
And gears and the like.

The decoder 7 has a function of distinguishing between a closed key code and an open key code transmitted from the transmitter 4.
The code generation in the transmitter 4 can be exemplified by a method of combining a plurality of frequencies in a matrix (DTMF), a method of modulating a pulse on a time axis (PTM), and a method of coding and modulating a pulse (PCM). The decoder 7 performs decoding in accordance with the modulation method on the transmission side, and is composed of a reception circuit including high-frequency amplification, detection, frequency conversion, demodulation, and a frequency filter, and the electronic control unit 1 having a decoding operation procedure. I have.

Here, assuming that the transmitter 4 transmits a closed key code, the information processing unit 8 identifies whether the transmitted signal is a closed key code or an open key code, and closes the actuator 6. Operate in lock direction. As a result, the lock arm 5 projects between the spokes to lock the wheel.

As described above, decoding is substantially processed in parallel with other jobs in the information processing section 8, so that information processing dedicated to the lock device is not required. Therefore, a wireless bicycle lock device can be provided at very low cost only by adding a small number of receiving circuits.

The operation of the above configuration will be described with reference to FIGS. First, when a signal from the transmitter is received in step S101, it is determined in step S102 whether the code is a signal for opening or closing the lock. In the case of a lock closing signal, the process proceeds to step S103, the actuator 6 operates, the lock arm 5 moves forward, and the wheels are locked in step S104. On the other hand, when it is determined in step S102 that the code is an open lock signal, the actuator 6 operates to retreat the lock arm 5 in step S105, and the wheel lock is released in step S107.

The lock arm 5 can escape.

In addition to this, the entire lock portion 3 is connected to the elastic mechanism 51.
, The lock arm 5 can have more room for escape, and locking by remote control can be performed more reliably.

As described above, since the opening and closing of the locked state of the bicycle can be remotely controlled by the operation of the transmitter 4, the lock can be released even when the user approaches the bicycle, and the user can start immediately.

Further, since the user does not need to directly operate the mechanical components of the lock mechanism, the safety can be improved without injuries such as pinching of fingers. Note that decoding is substantially processed in parallel with other jobs in the information processing unit 8, so that information processing dedicated to the lock device becomes unnecessary. This has the advantage that a wireless bicycle lock device can be provided only by adding an inexpensive receiving circuit.

[0037]

According to the present invention, since the opening and closing of the locked state of the bicycle can be remotely controlled wirelessly, the operability of the lock can be greatly improved. Also, even if the lock arm comes into contact with the spoke of the wheel during locking,
Since the tip of the lock arm has an acute angle, the lock arm can escape in either direction, and locking can be performed reliably.

In addition, since the entire lock portion is supported by the elastic mechanism, the lock arm can have more room for escape, and locking by remote control can be performed more reliably.
