Description

BICYCLE BEING CONNECTABLE TO ONE ANOTHER WITH BRAKE MODULATOR}

The present invention relates to a bicycle configured to detach two or more single-seat bicycles, wherein a plurality of bicycles are connected in a row to be used as a multi-seat bicycle or a bicycle configured to be used as a conventional single-seat bicycle. In a multi-seat bicycle, the present invention relates to an interconnectable bicycle having a brake modulator that causes all bicycles to be braked at one time according to the operation of the head occupant.

The bicycle is axially supported by the front fork end extending downward of the handle, while the handle is axially rotatably supported by the head tube of the frame with the saddle and pedals and is integrally formed with the rear fork end. The rear wheel is a shaft-supported structure, which is a means of riding that is driven by the occupant's power.

Most bicycles based on the above-described configuration are made in a single-seater format, but some multi-seater bicycles that can be carried by two or more people are also known.

7 is a view showing a typical configuration of a multi-seat bicycle proposed in the prior art, the frame (2) is formed long so that several people can ride, the front fork (4) is formed in front of the head tube (6) The front wheel 8 is axially supported while being supported horizontally so that the rear wheel 10 can be rotated. A rear fork 10 is formed at the rear, and the rear wheel 12 is axially supported.

Two or more saddles 14 are attached to the frame 2 to allow two or more passengers to ride at the same time, and the sprockets 18 and the pedals 20 are also provided on the lower chain stay 16 of the frame 2 by the number of occupants. It is arranged to be able to push bicycle together.

On the other hand, the handle 2 is also arranged in the frame 2 as many as the number of occupants, but only the front handle 22 can be actively steered and the rear handle 22 is provided in a structure without a steering function.

As another type of multi-seat bicycle, as shown in FIG. 8, the interconnectable bicycle having a configuration that can be converted to a multi-seat bicycle by connecting the single-seat bicycle back and forth is also disclosed in Korean Patent Laid-Open Publication No. 1999-0033140.

This type of bicycle has a front fork (4), a head tube (6), a rear fork (10), a top tube (24), a seat tube (26), and a down tube (28) arranged on the frame (2). At least it's like a normal single-seater bike.

However, when converting to a multi-seater bicycle by connecting the front and rear, separate the front wheels (8) from the front fork (4) of the rear side bicycle, and then support the rear wheels 12 together with the rear fork (10) of the leading bicycle. By doing so, it can be converted into a state in which two vehicles are connected by a bell. In the same way, when two bicycles are connected to the rear bicycle in a row, two or more can be connected in a row.

In addition, PCT Patent Publication No. WO 2002/26554 shows a configuration that can be converted to a two-seater bicycle by connecting a frame equipped only with rear wheels to the rear of a single-seater bicycle, and PCT Patent Publication No. WO 2006/080855 has two units. A bicycle that can be converted to a multi-seater bike by connecting a single-seater bike vertically or horizontally with an attachment is disclosed.

The interconnectable bicycle of the above-described configuration exhibits the following problems when used as a multi-seater bicycle.

As shown in FIG. 8, the single-seat bicycle is supported by the front fork 4, which is axially supported by the head tube 6, which is fixed to the front of the frame 2 at an angle to the front of the frame 2. have.

The front fork inclined as described above causes the front wheel to be inclined with respect to the ground during steering, thereby allowing the occupant to operate the steering wheel lightly and stably running.

However, when changing the direction of a multi-seater bicycle, only the leading bicycle can steer without difficulty and the rear bicycle has a severely opposite direction of steering as the front fork is connected to the rear wheel of the leading bicycle. The problem of tilting and falling occurs.

In other words, in a multi-seater bicycle with several cars in a row, the front fork of the rear bicycle always follows the front rear wheel, but when steering, the frame is reversed from the steering direction due to the change of direction of the rear fork that is inclined to the ground. It is pushed in the direction and can not travel.

Another problem is that when cycling on a multi-seater bicycle with several cars in series, the braking operation is only at the intention of the first occupant to be safe and comfortable. Anyone can operate the brakes arbitrarily, and the brake action will be inaccurate, and even if only the front passenger controls the brake by setting the rules, it is impossible to mechanically operate the brakes of the entire bicycle with the force of one person. Therefore, the safety of the driving can not be guaranteed.

As described above, the inventors of the present invention have a problem in which the head tube and the top tube, which form the frame of the bicycle, are arranged to rotate relative to each other, and the clutch means is interposed between both tubes. When used as a single-seater bicycle, there has been separately proposed an interconnectable bicycle that is configured to be integrally fixed between the two tubes by a clutch state, and to be unclutched when using a multi-seater bicycle.

It is therefore an object of the present invention to provide an interconnectable bicycle having a brake modulator configured to allow only the front passenger to operate the brakes of all the bicycles at one stroke when connecting several cars in a row and driving together. have.

The above object is an interconnectable bicycle which can be converted into a multi-seat bicycle by connecting the front fork of another single-seater bicycle to the rear wheel of a conventional single-seater bicycle, and coping with a change in the position of the brake lever provided on the ordinary bicycle. A brake modulator having a rotary encoder for outputting a pulse signal, a front bicycle connecting cable having a plug connected to the front bicycle, and a socket to which a plug extending from the rear bicycle is connected, between the rotary encoder and the brake modulator. An encoder cable for wired connection, a spool disposed inside the brake modulator to wind or unwind a branch line connected to a normal brake, a ratchet gear concentrically arranged on the spool, and a ratchet gear that is always fitted to the ratchet gear. Ratchet fingers with, ratchet fingers To the brake modulator consisting of a solenoid which causes the motor to deviate from the ratchet gear with its own force, a motor geared through the reduction gear to drive the spool, and a control board that generates a signal and recognizes a state to drive the solenoid and the motor. Can be implemented.

The brake modulator has a control plate therein, and the control panel includes a cable connection recognition unit for recognizing whether the plug is connected to the socket of the brake modulator of the front bicycle and whether the plug of the rear bicycle is connected to the socket. A power supply determination circuit configured to receive the output of the cable connection recognition unit and determine whether to supply power to each part, a volume recognition circuit converting and outputting a pulse signal output from the rotary encoder into a phase signal, and the solenoid; A pulse width modulation signal for generating a motor driving signal by combining a clock generation circuit and a frequency determination circuit for generating a signal waveform required for the operation of the motor, and a stepped waveform output from the frequency determination circuit and a phase signal output from the volume recognition circuit. The output circuit and the output of the volume recognition circuit A signal unit having a signal duration discrimination circuit that recognizes whether a change occurs within a predetermined time period, and recovers the signal from the front bicycle and receives the output of the signal duration discrimination circuit to control the output signal to the solenoid and the motor. An input / output control circuit which outputs a signal to the rear bicycle and outputs a motor driving signal and a solenoid driving signal at a time difference, and a solenoid driving circuit which independently drives the solenoid and the motor as output signals of the input / output control circuit, respectively, and a motor driving circuit It may be implemented in a configuration including a furnace.

In addition, the cable connection recognition unit includes a plug connection recognition circuit for recognizing the connection connection between the plug and the front bicycle socket, a socket connection recognition circuit for recognizing the connection connection between the socket and the rear bicycle plug.

The output signals from these plug connection recognition circuits and socket connection recognition circuits represent one of the front bicycle / rear bike / seat bicycle connected to the rear, and the rear bicycle and the floc connection when the output signal is only a signal of the flock connection recognition circuit. When the signal of both the recognition circuit and the socket connection recognition circuit is the bicycle connected in the middle, and when the signal of the socket connection recognition circuit is only the lead bicycle, the bicycle is connected back and forth when there is no signal output in both the plug connection recognition circuit and the socket connection recognition circuit. Not a single-seater bike.

The brake module of the first bicycle, in which the rear bicycle's plug is connected and the signal is output only from the socket connection recognition circuit, is supplied to the signal unit, the input / output control circuit, the solenoid drive circuit, and the motor drive circuit by the power supply judgment circuit. do.

In the signal unit, a frequency determining circuit that receives an output waveform of a clock generation circuit generating a waveform of a predetermined frequency outputs a signal of a predetermined frequency for driving the solenoid to the solenoid driving signal generating circuit while driving the motor. And outputting a stepped waveform, and the volume recognition circuit receiving the output of the rotary encoder recognizes whether the input signal is in the increase direction or the decrease direction, and outputs a signal in which the phase is determined to output a stepped waveform and phase in the pulse width modulation signal generation circuit. The signal duration discrimination circuit recognizes whether the output from the rotary encoder causes a change within a predetermined time and outputs the solenoid driving signal when a change occurs. Starts with a parallax faster than the motor drive signal And it outputs a control signal to cause.

The input / output control circuit controls the solenoid driving circuit and the motor driving circuit by receiving the output of the pulse width modulation signal generating circuit and the output of the solenoid driving signal generating circuit, but the output of the signal sustain determination circuit is applied, that is, the input / output When the output of the rotary encoder is changed by the brake lever operation in the control circuit and the motor drive signal having the duty ratio by the solenoid drive signal and the pulse width modulation signal is output, the solenoid is controlled to be driven before the motor. The output of the pulse width modulation signal generating circuit and the output of the solenoid driving signal generating circuit is transmitted to the rear bicycle.

In addition, when a state in which no change is maintained for a certain time during the brake operation, the input / output control circuit is controlled to block the solenoid drive signal and the motor drive signal by a signal that the signal sustain determination circuit recognizes and outputs the same. .

Accordingly, when the brake operation by the brake modulator according to the present invention is maintained without change for a predetermined time, the ratchet finger is engaged with the ratchet gear so that the current braking force can be maintained without power consumption, thereby minimizing the consumption of limited battery. Can be.

In addition, if the solenoid drive signal is output first with a shorter time difference than the motor drive signal in the input / output control circuit, the ratchet finger is always peeled off at the time when the motor starts to be driven, thereby ensuring a comfortable operation.

The solenoid and the motor driving signal output from the front bicycle and input to the input / output control circuit of the rear bicycle can brake control the entire bicycle connected to the rear at the same time when the signal displacement or attenuation is compensated while passing through the input / output control circuit. .

In the case of the rear bicycle, the power supply determination circuit in the control board cuts the power to the signal unit and supplies power only to the input / output control circuit, the motor driving circuit and the solenoid driving circuit.

In this way, the bicycles in the rear sequence are all controlled by signals output from the leading bicycle so that the brake operation according to the operation performed by the driver of the leading bicycle is simultaneously displayed on all the bicycles.

Interconnectable bicycles equipped with the brake modulator of the present invention, between the front and rear brake modulator of the wired connection when using as a multi-seat bicycle, the brake operation signal of the front passenger can be transmitted and applied to synchronize the brakes of all the bicycles In this case, the brake force acts as the power of the motor built into the brake modulator, so that the operation of the head occupant becomes light, and the driving safety of the entire bicycle is guaranteed even when used as a multi-seater bicycle, so that the user can travel without difficulty.

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

The bicycle according to the present invention has the configuration as shown in FIG.

That is, the front fork 4 supported by the head tube 6 axially supports the front wheel 8 at the front of the frame 2, and the rear fork 10 extends at the rear to support the rear wheel 12. On the other hand, the saddle 14, the handle 22, the brake lever 220, and the sprocket 18 and the pedal 20 are disposed on the frame 2, the typical single-seater bicycle, respectively Including a configuration in which a plurality of lines are connected in a row, but the front fork 4 of the rear bicycle is aligned with the rear fork 10 of the front bicycle so that the rear wheel 12 (the front wheel in the case of the rear bicycle) is jointly supported. In addition, the frame 2 is divided into a top tube 24 and a floating tube 60 so as to be relatively rotatable, and between the two tubes 24 and 60, the clutch means 30 and this clutch means ( 30) and a synchronizer 32 disposed between the front fork 4, in the case of a single-seater bicycle When the synchronizer 32 is released by the position movement of the clutch means 30 and both the tubes 24 and 60 are integrally connected, the position of the clutch means 30 is also changed by the movement of the clutch means 30. At the same time as the synchronizer 32 is connected, the two tubes 24 and 60 are configured to be converted into a relatively rotatable state.

In the bicycle having such a configuration, the brake modulator 72 of the present invention is mounted at a position which does not cause relatively interference with an external object such as, for example, the upper portion of the rear fork 10 or the lower side of the saddle 14.

More specifically, as illustrated in FIG. 2, the brake modulator 72 is a device for interlocking the V brake 120 provided in a conventional single-seater bicycle.

The brake modulator 72 is provided with a socket 722, and a plug fitted into the encoder cable 224 leading to the brake lever 22 and the socket 722 of the brake modulator 72 provided on the front bicycle. A connecting cable 720 with 724 is extended.

The plug 724 of the connecting cable 720 is inserted into the socket 722 of the brake modulator 72 provided in the front bicycle when used as a multi-seater bicycle to form an electric signal transmission path between the front and rear bicycle.

As the brake modulator 72 and the V brake 120 are connected by a branch line 122 divided into Y-shapes and are connected in duplicate with the normal brake wire 124, the V brake 120 is a brake modulator 72. Or in conjunction with the brake wire 124. In this case, the branch line 122 should be made of a very flexible wire so that it does not act as an interfering load when being pulled by the brake modulator 72 or pulled by the brake wire 124.

3 depicts a rotary encoder 222 embedded in the brake lever 220.

The rotary encoder 222 outputs a pulse signal in which two variable contacts vary in time with respect to a common fixed contact according to the operation of the brake lever 220, so that the volume of the signal unit 77 embedded in the controller board 74 is increased. A device for inputting to the recognition circuit 774.

Although the above-described configuration indicates that the brake type is V brake 120 in the bicycle of the present invention, the present invention is not limited to this and can be applied to other types of brakes, for example, U brakes or drum brakes without greatly changing the structure. .

In the case of using the bicycle of the present invention by interconnecting a multi-seat bicycle, as shown in FIG. 4, the plug 724 of the rear bicycle is connected to the socket 722 provided in the brake modulator 72 of the front bicycle. All brake modulators 72 are wired to operate simultaneously.

Inside the brake modulator 72, as shown in FIG. 5, circuit elements such as the battery 73, the control board 74, the motor 86, the solenoid 88, and the motor 86 are provided. Relating to the output gear 860 and the reduction gear 862 and the ratchet gear 864, the spool 866, and the solenoid 88 arranged concentrically to the reduction gear 862, the ratchet gear 864 is included. Mechanical elements, such as ratchet fingers 880, are disposed.

In addition, the internal circuit configuration of the control board 74 is a power supply unit 75, a plug connection recognition circuit 762 and a socket connection recognition consisting of a rectifying circuit 750 and a power supply determination circuit 752 as shown in FIG. A cable connection recognition unit 76 composed of a circuit 764, a clock generation circuit 770 and a frequency determination circuit 772, a volume recognition circuit 774, a pulse width modulation signal generation circuit 776, a signal duration determination circuit ( 778, a signal unit 77 composed of solenoid drive signal generation circuits 780, an input / output control circuit 80, a motor drive circuit 82, and a solenoid drive circuit 84.

The spool 866 is rotated by the motor 86 while winding one side of the branch line 122, or through the process of releasing the branch line 122 by the elastic restoring force applied by the spring of the existing brake conventional V brake It is arranged to operate 120.

In addition, the ratchet finger 880 is installed at a position that can be always fitted to the ratchet gear 864 by its own weight, usually restrained so that the spool 866 can not be rotated, if interlocked with the magnetic force of the solenoid 88 The ratchet gear 864 is released to act to release the spool 866.

As such, when the spool 866 is restrained by the ratchet finger 880, the branch line 122 cannot be released from the spool 866 even when the power supply to the motor 86 is interrupted. You can make it. In other words, if there is no change in the operation of the brake lever 220 for a predetermined time, the output from the rotary encoder 222 does not change. Accordingly, the signal continuity discriminating circuit 778 does not recognize the change and generates a “low” signal. When outputting, the input / output control circuit 80 cuts off the outputs of the motor driving circuit 82 and the solenoid driving circuit 84, and as a result, even if the motor 86 and the solenoid 88 become inoperative, the ratchet gear As the 864 is engaged with the ratchet finger 880, the brake state remains.

This structure is to stop the power supply to the motor 86 and the solenoid 88 if the brake lever 220 is maintained for more than a certain time without any change in the position while driving to help minimize the limited battery consumption.

In the control panel 74, the power supply unit 75 includes a rectifier circuit 750 and a power supply determination circuit 752. The battery 73 used here may be a general primary battery. Rechargeable secondary batteries may also be used by the rectifier circuit 750.

In addition, the rectifier circuit 750 may also be used to charge the rechargeable battery 73 with a current obtained through the solar cell 732 or the bicycle generator 734 from the outside.

The power supply unit 75 is connected to directly supply power to the cable connection recognition unit 76, the signal unit 77, the input / output control circuit 80, the motor driving circuit 82 and the solenoid driving circuit 84.

The cable connection recognition unit 76 includes a plug connection recognition circuit 762 that recognizes that the plug 724 is connected to the socket 722 of the front bicycle, and the plug 724 of the rear bicycle is connected to the socket 722 by the connection. And a socket connection recognition circuit 764 for recognizing that the signal is outputted, and the signals outputted from them represent the current use mode of the bicycle.

That is, when the plug 724 is inserted into the socket 722 of the front bicycle, the plug connection recognition circuit 762 outputs a “high” signal, and when the plug 724 of the rear bicycle is inserted into the socket 722, the socket is connected. The recognition circuit 764 outputs a high signal.

Accordingly, when either of the plug connection recognition circuit 762 and the socket connection recognition circuit 764 outputs a “high” signal, it means that the current state is used as a multi-seater bicycle, and conversely, both connection recognition circuits 762 ( 764) Outputting a “low” signal means that it is being used as a single-seater bike.

In the case of using a multi-seat bicycle, if the output signal "high" is output only from the socket connection recognition circuit 764, the state of the leading bike is output. If the output signal "high" only from the plug connection recognition circuit 762, the rear bicycle is The status, and both connection recognition circuits 762 and 764, output a “high” signal, indicating a state of being used as a bicycle in the middle turn.

In the case of a single-seat bicycle in which both of the connection recognition circuits 762 and 764 of the cable connection recognition unit 76 output a “low” signal, the power supply determination circuit 752 of the power supply unit 75 provides a cable. Power is supplied only to the connection recognizing unit 76 and power to other parts is cut off.

In the case of the first bicycle in which the "high" signal is output only in the socket connection recognition circuit 764, the signal supply unit 77, the input / output control circuit 80, the motor driving circuit 82 by the power supply determination circuit 752. ), Power is supplied to the solenoid driving circuit 84.

In addition, in the case of the rear bicycle or the bicycle of the intermediate order in which the "high" signal is output from the plug connection recognition circuit 762, the power supply to the signal unit 77 is cut off by the power supply determination circuit 752 and the motor is stopped. The driving signal required for the 86 and the solenoid 88 is in an inoperative state.

Due to the control of the cable connection recognition unit 76, the motors 86 and the solenoids 88 of all the bicycles except the leading bicycle are operated only in dependence on the driving signal transmitted from the front bicycle, and thus the leading bicycle driver. This results in all brakes on the bike running at the same time.

By the above configuration, when the bicycle of the present invention is used as a single-seat bicycle, power is not supplied to the motor 86 and the solenoid 88 of the brake modulator 72, but there is no choice but to use an existing mechanical brake. When used as a bicycle, the brakes of all the bicycles are operated at the same time by the electric signal generated by the driver of the leading bicycle.

By controlling the power supply of each unit through the power supply determination circuit 752, it is also possible to minimize the battery consumption of limited capacity.

In addition, in the case of the first bicycle, as the power is supplied to the signal unit 77, the clock generation circuit 770 generates and outputs a waveform of a predetermined frequency and inputs the frequency determination circuit 772 to the frequency determining circuit ( The waveform 772 divides the waveform input from the clock generation circuit 770 into a waveform of a constant frequency for driving the solenoid 88, outputs the waveform to the solenoid driving signal generation circuit 780, and generates a stepped waveform of a constant frequency. The pulse width modulated signal generator 776 outputs the pulse width modulated signal.

When the driver of the first bicycle operates the brake lever 220, the rotary encoder 222 outputs a pulse waveform that is changed by the position movement by the manipulation to the volume recognition circuit 774 through two output stages.

The volume recognition circuit 774 recognizes the parallax of the pulse signal input from the rotary encoder 222 to determine whether the rotation direction of the rotary encoder 222 is an up / down direction, converts it into a corresponding phase signal, and the pulse width. The modulated signal generating circuit 776 and the signal sustain discriminating circuit 778 are outputted to the modulated signal generating circuit 776.

The signal continuity determining circuit 778 determines whether the output of the rotary encoder 222, that is, whether or not the output of the pulse waveform due to the operation of the brake lever 220, and changes the "high" signal when a change occurs, If not present, the signal “low” is output to the input / output control circuit 80.

The pulse width modulation signal generation circuit 776 controls input / output of a pulse width modulation signal having a duty ratio by a combination of a stepped waveform input from the frequency determining circuit 772 and a phase signal input from the volume recognition circuit 774. Output to circuit 80.

Also, the solenoid drive signal generation circuit 780 outputs the solenoid drive signal based on the signal input from the frequency determination circuit 772 to the input / output control circuit 80.

The input / output control circuit 80 is controlled by the output signal of the signal sustain determination circuit 778 and outputs the output signals of the pulse width modulation signal generation circuit 776 and the solenoid drive signal generation circuit 780 to the motor driving circuit 82, respectively. And to the solenoid driving circuit 84.

Here, the motor driving circuit 82 controls the driving of the motor 86 by the duty ratio of the pulse width modulation signal, thereby minimizing the power consumption required for driving the motor 86.

The solenoid 88 is turned on and off by the output signal through the solenoid driving circuit 84.

Referring to the control process of the input / output control circuit 80 by the signal sustain determination circuit 778 in more detail, if the brake lever 220 is maintained at a certain position for a predetermined time, the output of the signal sustain determination circuit 778 is A low signal causes the input / output control circuit 80 to block the output signal so that the motor 86 and the solenoid 88 are not operated, and the brake lever 220 is adjusted to adjust the signal duration discrimination circuit 778. When the output of the signal becomes a “high” signal, the input / output control circuit 80 applies the output signal to both driving circuits 82 and 84 to operate the motor 86 and the solenoid 88.

In this way, when the brake lever 220 is left unmanaged for a predetermined time, the ratchet finger 880 is engaged with the ratchet gear 864, thereby maintaining the braking force without consuming power, thereby limiting The battery consumption can be minimized, and when the brake lever 220 is operated, the ratchet gear 864 is released from the ratchet finger 880 prior to the motor 86 to brake operation by rotating the spool 866. You lose.

At this time, when the signal output of the input / output control circuit 80 is set so that the output signal of the solenoid driving circuit 84 is output faster with an extremely short parallax than the output signal of the motor driving circuit 82, the ratchet finger 880 is always present. After releasing the ratchet gear 864, the operation of the motor 86 is started, and the brake operation is performed without mechanical force.

The interconnectable bicycle according to the present invention is a multi-seat bicycle when used as a multi-seater bicycle, and the bicycle after the first order receives a signal output from the front bicycle through the socket 722 and the plug 724 to receive the motor 86 and the solenoid 88. Since the output signal of the input / output control circuit 80 of the front bicycle is input to the input / output control circuit 80 of the rear bicycle in the signal transmission process, the input signal may be attenuated or deformed.

This problem can be solved by adding a compensation circuit to the input / output control circuit 80 to recover the attenuated or modified waveforms.

The compensating circuit is a signal that uniformly compensates for the front side rotation output signal input to the input / output control circuit 80 of the rear bicycle to the motor driving circuit 82 and the solenoid driving circuit 84 so that the brakes of all the bicycles are constant. Let it work

In addition, when the brake lever 220 returns to the home position, the "high" signal output of the signal continuity determining circuit 778 is maintained for a predetermined time from that moment, and then the "low" signal is output. Accordingly, the release state of the ratchet gear 864 is maintained for a predetermined time by the output signal of the solenoid driving circuit 84 through the input / output control circuit 78, and in the process, the branch line at the spool 866 with the spring force of the existing brake. The 122 is released and the brake is returned to its original state, and then the output to the solenoid driving circuit 791 is cut off.

When the brake modulator according to the present invention is used as a multi-seat bicycle, the brake can be operated while repeating the above-described operations. In this case, the brake operation outputs the signal of the rotary encoder 222 only from the first bicycle. The output signal of the input / output control circuit 80 of the front bicycle, which is applied to the input / output control circuit 80, but is applied to the input / output control circuit 80 of the front bicycle via the plug 724 inserted into the socket 722 of the front bicycle. The motor drive circuit 82 and the solenoid drive circuit 84 are controlled by the same and at the same time, the process of outputting through the socket 722 and the plug 724 of the rear bicycle again and again is repeated. Signals are transmitted in turn to the tail.

As a result, the entire multi-seater bicycle is braked at the same signal level, and the brakes of all bicycles are operated at the same time according to the operation of the rider of the leading bicycle, thus ensuring safe driving even when connecting multiple vehicles. do.
