Including a spring 130, but the locker 120 has a locking groove 121 is formed on one side of the outer periphery, the inside of the main housing 100 is lowered when the locker 120 is drawn out to the locking groove 121. A locking block 150 that is inserted to fix the position of the locker 120, and a release module 160 that lifts the locking block 150 so that the locker 120 can be retracted are installed and configured.

The main housing 100 is coupled to the frame of the bicycle and has a hollow interior to accommodate the main board 170, the rechargeable battery 180, the release module 160, etc. to be described below, and serves to provide an installation space for them. do.

The rear side of the main housing 100 may be formed by a separate rear cover 101 . In this case, after the rear cover 101 is firmly fixed to the frame of the bicycle, the main housing 100 is the rear cover 101 . It can be joined to the front.

An antenna for short-distance wireless communication such as RF or NFC may be built in the front of the main housing 100 to recognize a user's card, a charging means, such as a smartphone, and transmit a charging request to an external management server and receive a control signal In order to do this, an antenna for Wi-Fi or LTE communication may be built-in. Alternatively, a QR code may be attached to the front of the main housing 100 so that an app for payment can be executed when photographed with a smartphone.

The locking housing 110 extends below the main housing 100 . In this case, the locking housing 110 may be integrally configured with the main housing 100 , and the rear cover 101 may also be formed in a form that can seal both the main housing 100 and the locking housing 110 . .

The locking housing 110 accommodates the locker 120 and the return spring 130 and serves to guide the lock lever 140 , and for this purpose, is formed to extend downward of the main housing 100 . When the locker 120 is drawn out and the opening is closed, the locker 120 penetrates the inside of the wheel of the bicycle to block the spokes of the bicycle wheel to prevent the wheel from rotating, so the locking housing 110 accommodates a part of the wheel of the bicycle. provided in the form of

The locker 120 is accommodated in a slidable form inside the locking housing 110 and slid in a circular motion, and a return spring 130 that pulls the locker 120 in the direction of retracting the locker 120 to the inside of the locking housing 110. this is installed That is, when the locker 120 is withdrawn from the first end forming the opening of the locking housing 110 , the return spring 130 is inside the second end, which is the other end forming the opening of the locking housing 110 . It is installed to continuously pull the rocker 120 in the direction of the second end.

An arc-shaped lever hole 111 is formed through the front portion of the locking housing 110 in the same shape as the sliding path of the locker 120 . A portion of the lock lever 140 protrudes toward the front of the locking housing 110 through the lever hole 111 .

The locker 120 closes the opening of the locking housing 110 during withdrawal so that the wheel of the bicycle is completely accommodated between the opening of the locking housing 110 and the locker 120, so that the flesh of the bicycle is in contact and the wheel is no longer rotated serves to prevent it from happening. To this end, the locker 120 is formed in an arc shape and is slidably accommodated in the locking housing 110, is completely accommodated in the locking housing 110 when drawn in, and can close the opening of the locking housing 110 when withdrawing. is configured to

The other end of the locker 120 is coupled to the return spring 130 and is drawn into the locking housing 110 by the return spring 130 , and the lock lever 140 is coupled to one side so that the user can use the lock lever 140 . ) and slide the locker 120 to allow the locker 120 to be withdrawn to the outside of the locking housing 110 .

A locking groove 121 is formed in one side of the outer periphery of the locker 120 . The locking groove 121 serves to maintain the locking state without the locker 120 being retracted when the locking spring pulls the rocker 120 in the retracting direction after the rocker 120 is withdrawn. For this purpose, the locking groove ( The locking block 150 is inserted in 121).

The locking block 150 descends when the locker 120 is withdrawn and is inserted into the locking groove 121 of the locker 120 so that the locker 120 can maintain the locked state, and for this purpose, the block body ( 151), a locking rod 152 extending downward of the block body 151 and formed in a shape that can be inserted into the locking groove 121, and a release plate 153 extending to the side of the locking block 150. is composed by

The block body 151 serves as a center from which each component of the locking block 150 extends, and is installed so as to be lifted up and down inside the main housing 100 . At this time, the vertical direction means that the direction in which the locking housing 110 extends from the main housing 100 is the downward direction and the opposite is the upward direction, and the downward direction is oblique due to the nature of being coupled to the seat stay frame of the bicycle. , In describing the vertical direction of the present invention, this does not mean a vertical direction.

The locking rod 152 extends downward from the block body 151 and is formed in a shape that can be inserted into the locking groove 121 . At this time, the block body 151 and the locking rod 152 are in a state to continuously slide downward by gravity. do. However, the user holds the lock lever 140 and slides the locker 120 so that the locker 120 is withdrawn into the opening of the locking housing 110 and the locking groove 121 is located at the lower portion of the locking rod 152, The locking rod 152 is inserted into the locking groove 121, and when the user releases the lock lever 140 in this state, the locker 120 is moved back into the locking housing 110 by the locking rod 152. It becomes impossible to enter. This completes the locking operation by preventing the wheels of the bicycle from rotating.

However, when the user requests approval for use of the bicycle using a payment method, the locker 120 must be retracted to the inside of the locking housing 110 to return the bicycle to a state in which it can be used. To this end, a release module 160 is provided and a release plate 153 for transmitting the operation of the release module 160 to the block body 151 is provided.

The release plate 153 serves to transmit the operation of the release module 160 to the block body 151 so that the block body 151 and the locking rod 152 can be raised, and for this, the block body 151 It extends laterally from the block body 151 .

The lower surface of the release plate 153 is in contact with the eccentric protrusion 163 of the release module 160 when the release module 160 is driven, and when the release module 160 is further driven, it is pushed upward by the eccentric protrusion 163 . It is configured so that the block body 151 and the locking rod 152 can slide upward.

Through this, when the locking rod 152 is separated from the locking groove 121 , the locker 120 is drawn into the locking housing 110 by the return spring 130 .

On the other hand, the locking block 150 further includes a switch action rod 154 extending parallel to the release plate 153 from the block body 151, and a lock check switch 173 to be described later by the switch action rod 154 . ) and the release confirmation switch 172 are pressurized.

The release module 160 serves to release the locking of the locker 120 by raising the locking block 150 , and is installed inside the main housing 100 for this purpose. The release module 160 is configured to include a release motor 161 and a release cam 162 in which an eccentric projection 163 protrudes parallel to the rotation shaft while being coupled to the rotation shaft of the release motor 161 to rotate.

The release motor 161 serves to rotate the release cam 162 by coupling the release cam 162 to its rotation shaft. The release motor 161 is electrically connected to the main board 170 and the amount of rotation is adjusted by the control of the main board 170 , rotated at 180 degree intervals and protruded from the release cam 162 during the first 180 degree rotation. The protrusion 163 is positioned at the upper side, and the eccentric protrusion 163 is positioned at the lower side when it is rotated 180 degrees again or rotated 180 degrees in the reverse direction.

The release cam 162 is coupled to the rotation shaft of the release motor 161, and an eccentric projection 163 on one surface is spaced apart from the rotation shaft and protrudes parallel to the rotation shaft. Accordingly, as the release cam 162 rotates, the eccentric protrusion 163 moves from the bottom to the top and from the top to the bottom. In this process, when the eccentric protrusion 163 moves upward, it contacts the lower surface of the release plate 153 of the locking block 150 to raise the release plate 153, and the locking rod 152 rises to raise the locker 120 ) is unlocked.

However, after the locking block 150 is raised and the locker 120 is retracted into the locking housing 110, the user moves the lock lever 140 at any time to withdraw the locker 120 and the locking operation can be performed. Therefore, the release cam 162 must rotate to move the eccentric projection 163 downward again immediately after the upward movement of the eccentric projection 163 .

A release confirmation switch 172 is provided to determine the rotation timing of the release cam 162 , that is, the rotation timing of the release motor 161 . The release confirmation switch 172 is provided above the switch operation rod 154 of the locking block 150 , and is configured to operate by pressing when the locking block 150 is raised by the release module 160 . The release confirmation switch 172 is operated when pressed by the switch operation rod 154 and transmits operation information to the main board 170, and the main board 170 uses this to confirm that the lock of the locker 120 is released. Recognize and rotate the release motor 161 180 degrees after a set time.

Thereafter, when the user moves the lock lever 140 to perform a lock operation, the locking block 150 descends and the locking rod 152 is inserted into the locking groove 121 , and the switch operation rod 154 also descends. will do A lock check switch 173 is provided so that the bicycle can be returned by detecting that the locking operation has been performed. The lock check switch 173 is operated when the pressure by the switch operation rod 154 is released, and the main board 170 uses this to recognize that the locker 120 is locked and confirms that the bicycle has been returned to the management server. send. At this time, the operation by releasing the pressure by the switch operation rod 154 does not limit the operation by flowing current when the pressure is released, but the pressure by the switch operation rod 154 is released while the current flows. As a concept that also includes detecting a case in which the flow of current is cut off, it is preferable to interpret it as a concept that the main board 170 is configured to detect that the pressure of the switch operation rod 154 is released.

The main board 170 serves to control the rotation amount of the release motor 161 so that the release cam 162 can raise or lower the locking block 150, and for this purpose, the interior of the main housing 100 It is installed in and is connected to the rechargeable battery 180 to receive power. In addition, a charging module 171 for charging the rechargeable battery 180 may be mounted on the main board 170 .

The main board 170 rotates the release motor 161 when it is determined that the management server approves the use of the bicycle so that the eccentric protrusion 163 of the release cam 162 raises the locking block 150, and this This unlocks the bike and makes the bike ready for use.

After that, when the user moves the lock lever 140 to return the bicycle to withdraw the locker 120 and the locking block 150 is inserted into the locking groove 121 of the locker 120, the lock check switch 173 It detects the operation of the bicycle and transmits that the bicycle has been returned to the management server.

To this end, a first communication module for communicating with a remote management server and a second communication module for communicating with a user's payment means are mounted on the main board 170 . The first communication module is a communication module connectable to a commercial communication line such as Wi-Fi or LTE, and the second communication module is a communication module for recognizing a user's card or smart phone such as RF or NFC.

The user brings the card or smart phone close to the upper surface of the main housing 100 so that the second communication module can recognize the payment method. Alternatively, by photographing the QR code attached to the main housing 100 using a smartphone, the payment app is executed.

When payment is made, the use approval information of the bicycle is transmitted from the management server to the main board 170 , and the main board 170 rotates the release motor 161 of the release module 160 to raise the locking block 150 . so that the locker 120 is retracted to the inside of the locking housing 110 .

After using the bicycle, the user moves the lock lever 140 to withdraw the locker 120 to the outside of the locking housing 110, and when the withdrawal of the locker 120 is completed, the locking block 150 moves the locking groove ( 121) is inserted and descends, and through the lock check switch 173, the main board 170 recognizes that the lock is completely made and transmits it to the management server.

However, since the return of the bicycle is performed only by the user moving the lock lever 140 , some users may not return the bicycle and use it for their own sake. Accordingly, there is a need for a means for preventing the case of using the bicycle without approval.

The present invention is provided with a theft detection module to solve this problem. The theft detection module is installed in the main housing 100 , the locking housing 110 , or the main board 170 . The theft detection module may be composed of a GPS sensor, an acceleration sensor, a three-axis sensor, a geomagnetic sensor, etc., and the main board 170 is configured such that the measured value of the theft detection module is greater than or equal to the set value or the measured value is continuously detected for more than a set time. In this case, it is determined that the bicycle is being used without approval. For example, when the GPS coordinates are moved more than a set distance, when the measured value of the acceleration sensor is measured more than a set value, or when more than a set number of times is detected within a set time, this corresponds to this. In other words, when the bicycle is completely mounted at the rental or return location, there is no movement of the GPS, and the measured value of the acceleration sensor is also detected as vibration only when someone simply touches it or when a large vehicle moves, so theft is not done. This is because the number of measurements is small or the measurement value is small in the state.

As a result of determining the measured value transmitted from the theft detection module in the main board 170, if it is determined that the state is stolen, first, the psychological will of the actor must be reduced or the movement of the bicycle must be physically restricted.

First, in the present invention, a speaker is installed in the main housing 100 . The main board 170 transmits a theft warning voice to the speaker when it is determined that the bicycle is in a stolen state. In the theft warning voice, a voice instructing to bring the bicycle to the return position or move the lock lever 140 to the locked position is transmitted. By expressing these voices through a speaker at a high decibel level several times, it draws the attention of those around them, and accordingly psychologically shrinks the actors, causing them to return or throw away the bicycle and run away. Then, when it is determined that the bicycle is in a stolen state, the main board 170 transmits it to the management server, and allows the management server to transmit the stolen state information to an administrator or a law enforcement agency.

However, there may be cases where the actor continues to use the bicycle without regard to this. In this case, the auto braking unit 200 is provided to limit the physical movement of the bicycle.

The auto braking unit 200 is operated under the control of the main board 170 , and when it is determined that the bicycle is in a stolen state, the main board 170 operates the auto braking unit 200 to forcibly stop the bicycle.

The auto braking unit 200 for this purpose is installed on the brake wire 201 of the bicycle and includes a brake reel 210 on which the brake wire 201 is fixedly wound one or more times, and a brake operation actuator 221 , and one end It is configured to include a brake operation module 220 including a brake operation wire 222 wound on the brake reel 210 and the other end is coupled to the brake operation actuator 221 .

Accordingly, when a stop control signal is received from the main board 170, the brake operation actuator 221 is operated and the brake operation wire 222 is pulled, and the brake operation wire 222 is pulled while the brake reel 210 rotates. do. At this time, since the brake wire 201 of the bicycle is fixedly wound around the brake reel 210 , the brake wire 201 of the bicycle is eventually pulled to operate the brake of the bicycle. If the user directly operates the brake, the brake wire 201 is pulled as much as the user holds the brake lever, the brake reel 210 rotates as much as the brake wire 201 is pulled, and the brake reel 210 rotates. Since the brake wire 201 after the brake reel 210 is pulled only by the required amount, there is no problem at all for the user to manually operate the brake. In addition, when the brake reel 210 is rotated when the user manually operates the brake, the brake operation wire 222 is in a relaxed direction, so this also does not cause any problem in manually operating the brake by the user.

On the other hand, even if the bicycle is stopped because the brake of the bicycle is forcibly operated by the driving of the brake operation module 220 , since the capacity of the battery is limited to operate the brake actuator 221 indefinitely, when the battery is discharged, the brake operation actuator (221) returns to the initial position, and there may be a problem in which the brake is released.

Accordingly, the reel disk 230 and the parking module 240 are provided to minimize battery consumption and to maintain the forced operation of the brake even when the battery is discharged.

The reel disk 230 is formed in a disk shape and is fixed to the other end of the brake reel 210 to rotate together with the brake reel 210 . In addition, the parking module 240 makes contact with the outer periphery of the reel disk 230 after the operation of the brake actuator 221 is completed and suppresses rotation of the reel disk 230 so that the brake of the bicycle maintains an operating state.

Looking at the configuration of the reel disk 230 and the parking module 240 in more detail, the reel disk 230 has a plurality of parking grooves 231 indented along its circumference. The parking grooves 231 are formed at equal intervals, and must have a shape into which the parking rod 243 of the parking module 240, which will be described below, can be inserted.

The parking module 240 includes a parking motor 241, a plate-shaped parking plate 242 coupled to the rotation shaft of the parking motor 241 and rotated by the rotation of the parking motor 241, and the parking plate 242. It is configured to include a parking rod 243 vertically coupled to one end. In this parking module 240, when the parking motor 241 rotates in the first direction, the parking plate 242 presses the parking rod 243 toward the reel disk 230, and the parking rod 243 rotates the reel disk. It is seated in the parking groove 231 of the 230 . Then, the reel disk 230 is prevented from rotating, and accordingly, the rotation of the brake reel 210 is suppressed, so that the brake of the bicycle can be maintained in an operating state.

Thereafter, when the stolen bicycle is retrieved, or the bicycle is determined to be stolen by the user's mistake and the brake is forcibly operated, the management server is requested to release the brake operation, and the management server forcibly applies the brake. When a command to release the operation is received, the main board 170 rotates the parking motor 241 in a second direction opposite to the first direction so that the parking rod 243 can be separated from the parking groove 231 . . Then, the reel disk 230 is in a rotatable state, and accordingly, the brake reel 210 is also rotatable, so that the forced operation of the bicycle brake is released.

However, when the rotation suppression of the reel disk 230 is configured using only the parking motor 241 , the parking motor 241 rotates in the first direction, but the parking rod 243 is seated in the parking groove 231 . When the operation of the parking motor 241 is stopped when the operation of the parking motor 241 is stopped, the parking rod 243 cannot suppress the rotation of the reel disk 230 . In this case, the brake operation actuator 221 recognizes that the parking is completed and stops driving, and the reel disk 230 and the brake reel 210 are rotated to release the forced braking of the bicycle.

In addition, even when the parking motor 241 is rotated in the second direction to separate the parking rod 243 from the parking groove 231, the parking plate 242 is rotated due to vibration or impact during use of the bicycle and the parking rod ( 243 may be inserted into the parking groove 231 of the reel disk 230 . In this case, if the user is operating the bicycle at high speed, there is a risk of leading to a serious accident.

In order to solve this problem, continuously driving the parking motor 241 in the first direction during the forced braking operation and continuously driving the parking motor 241 in the second direction when the forced braking is released also causes the battery to be discharged. will result in

Therefore, even if the driving power is removed after driving the parking motor 241 for a set time, the parking rod 243 is continuously pressed in the first direction during the forced braking operation, and when the forced braking is released, the parking rod 243 is removed. Structural means shall be taken to prevent movement in one direction.

In order to solve this problem, the present invention is formed through the parking plate 242 at the other end opposite to the parking rod 243 based on the point coupled to the rotation shaft of the parking motor 241 , the rotation shaft of the parking motor 241 . A status maintenance hole 244 formed in an arc concave toward 242) is configured to include a holding spring 246 that pulls in the direction of the other end.

To this end, the parking plate 242 extends in the other end direction with respect to the rotation axis of the parking motor 241 and has a form in which it is expanded. At the other end side of the parking plate 242 , a status maintenance hole 244 is formed in an arc shape concave toward the rotation axis of the parking motor 241 . That is, it has a long hole shape, the middle of which is curved in the direction of the parking motor 241 , and the status quo rod 245 is slidably provided inside the hole.

At this time, the parking plate 242 is preferably configured as a pair of parallel, through which the parking rod 243 can be firmly fixed to the parking plate 242, the status quo rod 245 is also more stable The state of being inserted into the status quo hole 244 may be maintained. In addition, it is preferable that separation prevention holes having a diameter larger than the width of the status maintenance hole 244 are coupled to both ends of the status maintenance rod 245 to prevent the status maintenance rod 245 from being separated to the outside of the parking plate 242 . do.

Looking at the state of use of these configurations, as shown in FIG. 6B , when the parking motor 241 rotates in the first direction, the parking rod 243 descends and the status quo hole 244 rises. At this time, assuming that the lower end of the current maintaining hole 244 is the first end and the upper end of the current maintaining hole 244 is the second end, the current maintaining rod 245 is pulled by the current maintaining spring 246 to the first of the current maintaining hole 244 . sliding towards the end. And since the parking plate 242 is continuously pressed in the first direction by the current maintenance spring 246 even when the operation of the parking motor 241 stops thereafter, when the driving of the parking motor 241 is completed, the parking rod ( Even if 243) is not seated in the parking groove 231 of the reel disk 230, even if the reel disk 230 rotates a little in the brake release direction, the parking rod 243 is immediately inserted into the parking groove 231 and the brake The forced operation state is maintained.

When the parking motor 241 rotates in the second direction, the parking rod 243 rises and the status quo hole 244 descends. At this time, the status maintenance rod 245 is pulled by the status maintenance spring 246 to slide toward the second end of the status maintenance hole 244 . Then, even when the operation of the parking motor 241 is stopped, the parking plate 242 is continuously pressed in the second direction by the current maintenance spring 246 as shown in FIG. It is possible to prevent the parking rod 243 from being inserted into the parking groove 231 .

In the present invention having the above configuration, when the locker 120 is withdrawn, the locking block 150 is naturally seated in the locking groove 121 to perform a locking operation, and the release module 160 causes the locking block 150 to There is an effect that the release operation is carried out by a simple operation of raising it.

In addition, the present invention has the effect that it is possible to easily perform billing with a smartphone or the like and request unlocking of the bicycle.

In addition, the present invention has the effect of guiding the detection of theft and forcibly stopping the operation of the bicycle.
