[Embodiment 1]
FIG. 1 is a diagram showing a schematic configuration of an electronic bicycle lock 1 according to this embodiment. FIG. 2 is a cross-sectional view taken along line II-II of FIG.

As shown in FIGS. 1 and 2, the electronic bicycle lock 1 includes a housing 2, a bolt 3, a motor 4, a circuit board 5, a control device 6, a battery 7, a blocking mechanism 9, A power transmission mechanism 10 , a support member 11 ( FIG. 2 ), a spring 12 ( FIG. 2 ), and a battery case 13 are provided. The power transmission mechanism 10 includes a worm gear 8 and gears 15 . The power transmission mechanism 10 transmits the torque of the motor 4 to the bolt 3 .

Housing 2 includes an upper housing 21 and a lower housing 22 . Upper housing 21 accommodates motor 4 , circuit board 5 , control device 6 , battery 7 , worm gear 8 , shutoff mechanism 9 , battery case 13 , and gear 15 . The bolt 3 is housed in the upper housing 21 and the lower housing 22 . A control device 6 and an antenna (not shown) for receiving radio waves from a remote controller (not shown) are provided on the circuit board 5 .

The latch 3 is used to limit the rotation of the bicycle wheel. Specifically, the latch 3 is utilized to limit the rotation of the spokes of the wheel. The bolt 3 has a shape in which a part of the ring is notched. A tooth groove 31 is formed in the bolt 3 . The tooth groove 31 is provided on the outer peripheral side of the bolt 3 . The latch 3 further has a knob 32 for manual operation.

A battery 7 supplies power to the motor 4, the control device 6 and the antenna. The battery 7 is housed in a battery case 13 .

The motor 4 includes a shaft 41 that is an output shaft. Shaft 41 is rotatable in the direction of arrow P1.

Worm gear 8 includes a worm 81 and a worm wheel 82 . The worm 81 is also called a screw gear. The worm wheel 82 is also called a helical gear, a helical gear, or a helical gear.

A worm 81 is attached to the shaft 41 . Specifically, the worm 81 is attached to the tip of the shaft 41 . More specifically, the worm 81 has a through hole in the direction of the rotation axis, and the shaft 41 is inserted into the through hole. That is, the worm 81 is rotatable in the direction of arrow P1 shown in FIG.

The worm 81 and the worm wheel 82 are in mesh. The worm wheel 82 is rotatable about the shaft 18 shown in FIG. 2 in the direction of arrow P2 shown in FIG. The lead angle of the tooth space of the worm 81 is set small. Therefore, it becomes difficult to transmit the rotation from the worm wheel 82 to the worm 81 side. That is, the worm 81 cannot be rotated from the worm wheel 82 side. Such a mechanism is called self-locking.

The gear 15 and the tooth groove 31 of the bolt 3 are in mesh. The bar 3 is rotatable in the directions of arrows P3 and P4 shown in FIG.

The gear 15 is fitted in the worm wheel 82 (see FIG. 2). The rotation axis of the gear 15 and the rotation axis of the worm wheel 82 are the same. For example, the gear 15 has predetermined unevenness (not shown) on the surface facing the worm wheel 82 . The worm wheel 82 also has predetermined unevenness (not shown) on the surface facing the gear 15 . The gear 15 is fitted to the worm wheel 82 due to the unevenness of the gear 15 and the unevenness of the worm wheel 82 .

The gear 15 is formed with an opening 15a. The gear 15 rotates around the center of the opening 15a. The rotation axis of gear 15 is parallel to the Y-axis. Gear 15 is typically a spur gear.

The blocking mechanism 9 is a mechanism for blocking the transmission path for transmitting the rotational force of the motor 4 to the bolt 3 . Specifically, the blocking mechanism 9 includes a link mechanism 92 and a key cylinder 93 . A mechanical key is inserted into the key cylinder 93 . The key cylinder 93 is, for example, a pin tumbler lock. The key cylinder 93 has an outer cylinder 931 and an inner cylinder 932 . The inner cylinder 932 is rotatable with respect to the position-fixed outer cylinder 931 by operation using a mechanical key. For convenience of explanation, the keyhole is not shown in FIG. 2 and FIG. 4 which will be described later.

The link mechanism 92 includes multiple links (nodes) 921 , 922 , 923 , multiple joints 925 , 926 (see FIG. 2 ), and a shaft 924 . Links 921, 922, and 923 are rod-shaped parts. Each joint 925, 926 is a joint for rotation.

As shown in FIG. 2 , the link 921 and the link 922 are connected by a joint 925 . More specifically, the end of the link 921 on the side of the link 922 and the lower end of the link 922 are connected by a joint 925 . Link 922 and link 923 are connected by joint 926 . Specifically, one end of the link 922 side of the two ends of the link 923 and the upper end of the link 922 are connected by a joint 925 .

Link 922 is fixed to another member by shaft 924 . In this example, the shaft 924 is provided at the central portion of the link 922 in the extending direction.

Of the two ends of the link 921 , the end 921 a opposite to the link 922 is inserted into the opening 15 a of the gear 15 . In this example, the link 921 has a cylindrical shape except for the link 922 side. Gear 15 is supported by link 921 and rotates around link 921 . Of the two ends of the link 923 , the end 923 a opposite to the link 922 is connected to the bottom surface of the inner cylinder 932 of the key cylinder 93 by a joint 927 .

Support member 11 supports one end of spring 12 . The other end of the spring 12 abuts the end face of the worm wheel 82 . The spring 12 urges the worm wheel 82 in the direction of the gear 15 (direction of arrow P21, negative direction of the Y-axis). Thereby, the worm wheel 82 and the gear 15 are fitted. A rotating shaft 18 passes through the center of the spring 12 . Note that the spring 12 may bias the worm wheel 82 via another member.

The position of each link 921-923 of the link mechanism 92 in FIG. 2 is the default position. Specifically, the positions of the links 921 to 923 in FIG. 2 are the positions when the locking and unlocking operations of the latch 3 are performed using a remote controller (not shown).

Next, the locking and unlocking operations of the latch 3 using the remote controller will be described.

The motor 4 is driven based on commands from the control device 6 . The motor 4 is rotatable in forward and reverse directions. The "forward rotation direction" is the clockwise direction when the motor 4 is viewed from the shaft 41 side in the positive direction of the X axis. The "reverse direction" is the counterclockwise direction when the motor 4 is viewed from the shaft 41 side in the positive direction of the X axis.

The remote controller transmits an unlocking signal instructing unlocking or a locking signal instructing locking to the electronic bicycle lock 1 based on a user's operation. Bluetooth (registered trademark) is typically used for communication between the remote controller and the electronic bicycle lock 1 . An example of a remote controller is a smart phone.

Specifically, the control device 6 receives the unlocking signal and the locking signal via the antenna. When the control device 6 receives the lock signal, it rotates the motor 4 in the normal direction. In this case, the worm 81 attached to the shaft 41 rotates in the same direction as the forward rotation direction. When the worm 81 rotates in that direction, the worm wheel 82 rotates counterclockwise in the state shown in FIG. As a result, the gear 15 engaged with the worm wheel 82 also rotates counterclockwise in the state shown in FIG. As a result, the latch 3 rotates clockwise (in the direction of arrow P3) in the state shown in FIG. As a result, the latch 3 moves from the unlocked position to the locked position.

On the other hand, when the control device 6 receives the unlocking signal, it rotates the motor 4 in the reverse direction. In this case, the worm 81 attached to the shaft 41 rotates in the same direction as the reverse direction. When the worm 81 rotates in that direction, the worm wheel 82 rotates clockwise in the state shown in FIG. As a result, the gear 15 engaged with the worm wheel 82 also rotates clockwise in the state shown in FIG. As a result, the bolt 3 rotates counterclockwise (in the direction of arrow P4) in the state shown in FIG. As a result, the latch 3 moves from the locked position to the unlocked position.

Next, manual unlocking and locking operations will be described with reference to FIGS. 3 and 4. FIG. Such manual operation is performed when unlocking and locking cannot be performed due to the battery 7 running out, the control device 6 malfunctioning, the motor 4 malfunctioning, or the like. Manual operation is also performed when the remote controller runs out of battery or malfunctions. Manual operation is operation using a mechanical key. The mechanical key is used as an emergency key in this example.

FIG. 3 is a diagram for explaining manual operation using the mechanical key 100. FIG. 4 is a sectional view taken along line IV-IV in FIG. 3. FIG.

As shown in FIG. 3, the user inserts the mechanical key 100 into the inner cylinder 932 of the key cylinder 93 . When the user rotates the mechanical key 100 clockwise (in the direction of arrow P31) as seen from the user, the inner cylinder 932 rotates in the same direction as the mechanical key 100 (in the direction of arrow P41), as shown in FIG. Rotate.

As a result, the joint 927 moves by the rotation of the inner cylinder 932 with the center of the bottom surface of the inner cylinder 932 as the center of rotation. Specifically, the joint 927 moves in the negative direction of the Z-axis and in the negative direction of the Y-axis.

The movement of the joint 927 causes the link 923 to move at least in the negative direction of the Y axis. As a result, link 922 connected to link 923 rotates about axis 924 in the direction of arrow P43. As a result, the link 921 connected to the link 922 moves in the positive direction of the Y axis within the opening 15a of the gear 15 .

Due to the movement of the link 921, the end 921a of the link 921 moves the worm wheel 82 in the positive direction of the Y axis (direction of arrow P45) as shown in FIG. . As the worm wheel 82 moves in the positive direction of the Y axis, the worm wheel 82 moves away from the gear 15 . As a result, the engagement between the gear 15 and the worm wheel 82 is released.

As described above, the power transmission mechanism 10 for transmitting the torque of the motor 4 to the bolt 3 cuts off the transmission path of the torque. As a result, the user can freely operate the knob 32 of the latch 3 regardless of the above-described self-locking by the worm gear 8 consisting of the worm 81 and the worm wheel 82 .

For example, when the user operates the knob 32 in the direction of arrow P32 in the state of FIG. 3, the latch 3 also moves in the direction of arrow P32. Thereby, the position of the bolt 3 can be moved from the locked position to the unlocked position. Further, by operating the knob 32 in the direction opposite to the arrow P32 at the unlocked position, the position of the latch 3 can be moved from the unlocked position to the locked position.

(Brief Summary)
(1) As described above, the electronic bicycle lock 1 includes the bolts 3 that limit the rotation of the spokes of the wheel, and the bolts 3 that rotate in the forward direction to move the bolts 3 to the locked position and rotate in the reverse direction. a motor 4 that moves the bolt 3 to the unlocked position by moving the bolt 3, a power transmission mechanism 10 that transmits the rotational force of the motor 4 to the bolt 3, and a control device that controls the rotation of the motor 4 based on a command received from the outside. 6. The electronic bicycle lock 1 receives an operation using at least the mechanical key 100 when control by the control device 6 is not performed, thereby interrupting the transmission path of the rotational force by the power transmission mechanism 10 .

According to such a configuration, locking and unlocking can be performed by remote controller operation and manual operation using the mechanical key 100, respectively. In particular, if the battery 7 runs out, the controller 6 malfunctions, the motor 4 malfunctions, the batteries in the remote controller run out, or the remote controller malfunctions, and unlocking and locking become impossible, manual unlocking and locking are possible. It is possible to do

(2) Motor 4 includes shaft 41 . The power transmission mechanism 10 includes a worm 81 attached to the shaft 41 , a worm wheel 82 that meshes with the worm 81 , and a gear 15 that fits into the worm wheel 82 and has the same rotational axis as the worm wheel 82 . The bolt 3 is formed with a tooth groove 31 that meshes with the gear 15. - 特許庁

According to such a configuration, even if the power transmission mechanism 10 has a self-locking mechanism with the worm 81 and the worm wheel 82, locking and unlocking can be performed manually.

(3) The electronic bicycle lock 1 further includes a blocking mechanism 9 that blocks the transmission path based on the operation of rotating the mechanical key 100 . According to such a configuration, the user can cut off the transmission path by the power transmission mechanism 10 by rotating the mechanical key 100 .

(4) Based on the operation of rotating the mechanical key 100 , the blocking mechanism 9 moves the worm wheel 82 away from the gear 15 . With such a configuration, the engagement between the worm wheel 82 and the gear 15 can be released.

(5) The blocking mechanism 9 has an outer cylinder 931 and an inner cylinder 932, and the mechanical key 100 allows the inner cylinder 932 to move in a first direction with respect to the outer cylinder 931 and in a second direction opposite to the first direction. The key cylinder 93 rotatable in two directions and the inner cylinder 932 rotate in the first direction, thereby separating the worm wheel 82 from the gear 15 and rotating the inner cylinder 932 in the second direction. Thus, a link mechanism 92 for fitting the worm wheel 82 to the gear 15 is included.

According to such a configuration, the user can cut off the transmission path by the power transmission mechanism 10 by rotating the mechanical key 100 in the first direction, and further rotate the mechanical key 100 in the second direction. Thus, the transmission path by the power transmission mechanism 10 can be constructed (the interrupted state is eliminated).

(6) The electronic bicycle lock 1 further includes a spring 12 that biases the worm wheel 82 toward the gear 15 . With such a configuration, the worm wheel 82 and the gear 15 can be brought into a fitted state.

(Modification)
(1) In the above description, by releasing the engagement between the worm wheel 82 and the gear 15, the transmission path of the rotational force of the motor 4 by the power transmission mechanism 10 to the bolt 3 is cut off. However, it is not limited to this.

The blocking mechanism 9 may be configured to disengage the latch 3 and the gear 15 by moving the worm wheel 82 and the gear 15 . That is, the blocking mechanism 9 may be configured such that the worm wheel 82 and the gear 15 are moved in the positive direction of the Y-axis by operating the mechanical key 100, and as a result, the gear 15 and the bolt 3 are disengaged. .

(2) The electronic bicycle lock 1 is configured such that the motor 4 rotates in the forward direction to move the latch 3 to the unlocked position, and rotates in the reverse direction to move the latch 3 to the locked position. may be configured.

(3) In the electronic bicycle lock 1 described above, the configuration in which the latch 3 has the tooth grooves 31 has been described as an example. In other words, the configuration in which the bolt 3 directly meshes with the gear 15 has been described as an example. However, it is not limited to this.

The bolt 3 does not necessarily have to have the tooth spaces 31 . That is, the bolt 3 may not have the tooth grooves 31 formed therein. Alternatively, the bolt 3 may be connected to another gear component (not shown), and the gear component may mesh with the gear 15 .

In the case of such a configuration, as the gear 15 rotates, the bolt 3 rotates together with the gear component. With such a configuration, the same effect as that of the electronic bicycle lock 1 described above can be obtained.

[Embodiment 2]
In Embodiment 1, the configuration in which the transmission path of the torque of the motor 4 by the power transmission mechanism 10 can be cut off by rotating the mechanical key 100 has been described as an example. In the present embodiment, a configuration will be described in which the cover is opened with the mechanical key 100 and then the transmission path of the torque of the motor 4 through the power transmission mechanism 10 is cut off directly by hand without using the mechanical key 100 .

FIG. 5 is a diagram showing a schematic configuration of an electronic bicycle lock 1A according to this embodiment. 6 is a cross-sectional view taken along line XI-XI in FIG. 5. FIG.

As shown in FIGS. 5 and 6, the electronic bicycle lock 1A includes a housing 2, a bolt 3, a motor 4, a circuit board 5, a control device 6, a battery 7, a blocking mechanism 109, It includes a power transmission mechanism 10, an openable cover 150, a lock receiving portion 171, an antenna (not shown), a support member 11 (FIG. 6), and a spring 12 (FIG. 6).

Thus, the electronic bicycle lock 1A differs from the electronic bicycle lock 1 of Embodiment 1, which has the blocking mechanism 9, in that the blocking mechanism 109 is provided. Further, the electronic bicycle lock 1A is different from the electronic bicycle lock 1 of Embodiment 1, which does not have the opening/closing cover 150 and the lock receiving portion 171, in that it is provided.

The blocking mechanism 109 is housed in the upper housing 21 . Although the details will be described later, the blocking mechanism 109 is a mechanism for blocking the transmission path for transmitting the rotational force of the motor 4 to the bolt 3, like the blocking mechanism 9 of the first embodiment. Specifically, the blocking mechanism 109 includes a link mechanism 92A, a spring 94 (FIG. 6), and a support member 95 (FIG. 6).

As shown in FIG. 6, the link mechanism 92A includes links 921 and 922, a joint 925, and a shaft 924. As shown in FIG. Thus, the link mechanism 92A differs from the link mechanism 92 of the first embodiment in that it does not include the link 923 and the joint 926. As shown in FIG. The link mechanism 92A further includes an operation portion 929. As shown in FIG. The operation section 929 is connected to the link 922 . The operating portion 929 extends from the link 922 in the negative direction of the X axis.

The openable cover 150 is provided on the upper housing 21 . Although the details will be described later, the openable cover 150 is a cover that can be unlocked and locked with the mechanical key 100 . The openable cover 150 includes a body portion 151 , a pin 152 , a key cylinder 153 and a lock plate 154 . The body portion 151 is a plate-like member. The body portion 151 is typically made of the same material as the upper housing 21 . The body portion 151 is typically made of resin.

A mechanical key 100 is inserted into the key cylinder 153 . Key cylinder 153 is, for example, a pin tumbler lock. The key cylinder 153 has an outer cylinder 1531 and an inner cylinder 1532 . The outer cylinder 1531 is fixed to the body portion 151 . The inner cylinder 1532 is rotatable with respect to the position-fixed outer cylinder 1531 by operating the mechanical key 100 .

The lock plate 154 is fixed to the end surface (bottom surface) of the inner cylinder 932 . The lock receiving portion 171 is installed on the upper housing 21 . The lock receiving portion 171 is installed on the inner wall surface (typically, the ceiling surface) of the upper housing 21 . The lock receiving portion 171 is installed at a position corresponding to the lock plate 154 . The lock receiving portion 171 is a member that locks the lock plate 154 .

FIG. 7 is a diagram for explaining the lock receiving portion 171 and the lock plate 154. FIG.
As shown in FIG. 7, the lock plate 154 has a body portion 154a and a convex portion 154b. In this example, the body portion 154a is attached to the inner cylinder 932 . As a result, the lock plate 154 rotates in the same direction as the inner cylinder 1532 (direction of arrow P71) as the inner cylinder 1532 of the key cylinder 153 rotates.

The lock receiving portion 171 engages the convex portion 154b of the lock plate 154 . The lock receiving portion 171 has wall surfaces 171a and 171b parallel to the YZ plane. The wall surface 171a is closer to the body portion 151 (positive direction of the X axis) than the wall surface 171b. The wall surface 171a prevents the lock plate 154 from moving in the negative direction of the X axis. The wall surface 171b prevents the lock plate 154 from moving in the positive direction of the X axis.

8 is a cross-sectional view taken along line XIII-XIII of FIG. 7. FIG.
As shown in FIG. 8, lock plate 154 moves in the direction of arrow P81 and the direction of arrow P82 as inner cylinder 1532 is rotated by operation of mechanical key 100. As shown in FIG.

The lock receiving portion 171 further has a wall surface 171c parallel to the XZ plane. The projection 154b of the lock plate 154 is locked by the wall surface 171c. Specifically, the rotation of the lock plate 154 in the direction of the arrow P82 is stopped by the wall surface 171c.

Next, manual unlocking and locking operations will be described with reference to FIGS. 9 to 11. FIG. Such manual operation is performed when there is a problem, such as when the battery 7 runs out, as described in the first embodiment. Since the operation of the remote controller is the same as that of the electronic bicycle lock 1 of Embodiment 1, repeated description will be omitted.

FIG. 9 is a diagram for explaining an unlocking operation using the mechanical key 100. FIG.
As shown in FIG. 9, when the user rotates the mechanical key 100 in the counterclockwise direction (the direction of the arrow P91), the inner cylinder 932 and the lock plate 154 rotate in the same direction as the mechanical key 100. Rotate. As a result, the lock on the lock plate 154 by the lock receiving portion 171 is released.

Thereafter, the user moves (rotates) the openable cover 150 in the direction of the arrow P92 with the pin 151 as the rotation axis. This operation opens the openable cover 150 . The operation may be an operation by the user to move the mechanical key 100 in the direction of the arrow P92, or an operation by the user to move the mechanical key 100 in the direction of the arrow P92 while holding a grip portion (not shown).

FIG. 10 is a diagram showing a state after the openable cover 150 has been moved in the direction of arrow P92. 11 is a cross-sectional view taken along line XI-XI of FIG. 10. FIG.

As shown in FIGS. 10 and 11, the blocking mechanism 109 is exposed by opening the openable cover 150 with the mechanical key 100. As shown in FIG. When the user holds the operation unit 929 and applies a force in the positive direction of the Y axis (the direction of the arrow Q), the link 922 rotates around the axis 924 in the direction of the arrow P113. As a result, the link 921 connected to the link 922 moves in the positive direction of the Y axis within the opening 15a of the gear 15 .

Due to the movement of the link 921, the end 921a of the link 921 moves the worm wheel 82 in the positive direction of the Y axis (direction of arrow P115) as shown in FIG. 11 against the bias of the spring 94. . As the worm wheel 82 moves in the positive direction of the Y axis, the worm wheel 82 moves away from the gear 15 . As a result, the engagement between the gear 15 and the worm wheel 82 is released.

As described above, the power transmission mechanism 10 for transmitting the torque of the motor 4 to the bolt 3 cuts off the transmission path of the torque. As a result, the knob 32 of the latch 3 can be freely operated regardless of the above-described self-locking by the worm gear 8 consisting of the worm 81 and the worm wheel 82 .

For example, when the user operates the knob 32 in the direction of arrow P101 in the state of FIG. 10, the latch 3 also moves in the direction of arrow P101. Thereby, the position of the bolt 3 can be moved from the locked position to the unlocked position. Further, by operating the knob 32 in the direction opposite to the arrow P101 at the unlocked position, the position of the latch 3 can be moved from the unlocked position to the locked position.

It should be noted that when the user releases the operation unit 929, the force of the spring 94 returns to the state shown in FIG. Thereby, the gear 15 and the worm wheel 82 are fitted.

(Brief Summary)
(1) As described above, the electronic bicycle lock 1A includes the bolts 3 that restrict the rotation of the spokes of the wheel, and the bolts 3 that rotate in the forward direction to move the bolts 3 to the locking position and rotate in the reverse direction. a motor 4 that moves the bolt 3 to the unlocked position by moving the bolt 3, a power transmission mechanism 10 that transmits the rotational force of the motor 4 to the bolt 3, and a control device that controls the rotation of the motor 4 based on a command received from the outside. 6. When the control device 6 is not performing control, the electronic bicycle lock 1</b>A accepts an operation using at least the mechanical key 100 , thereby blocking the transmission path of the rotational force through the power transmission mechanism 10 .

According to such a configuration, locking and unlocking can be performed by remote controller operation and manual operation using the mechanical key 100, respectively. In particular, if the battery 7 runs out, the controller 6 malfunctions, the motor 4 malfunctions, the batteries in the remote controller run out, or the remote controller malfunctions, and unlocking and locking become impossible, manual unlocking and locking are possible. It is possible to do

(2) Motor 4 includes shaft 41 . The power transmission mechanism 10 includes a worm 81 attached to the shaft 41 , a worm wheel 82 that meshes with the worm 81 , and a gear 15 that fits into the worm wheel 82 and has the same rotational axis as the worm wheel 82 . The bolt 3 is formed with a tooth groove 31 that meshes with the gear 15. - 特許庁

According to such a configuration, even if the power transmission mechanism 10 has a self-locking mechanism with the worm 81 and the worm wheel 82, locking and unlocking can be performed manually.

(3) The electronic bicycle lock 1A includes a housing 2 (specifically, an upper housing 21) containing a blocking mechanism 109 for blocking the transmission path, a housing 2 (more specifically, an upper housing 21) containing at least the motor 4 and the blocking mechanism 109; An opening/closing cover 150 provided and capable of being locked and unlocked by the mechanical key 100 is further provided. By opening the openable cover 150 with the mechanical key 100, the blocking mechanism 109 is exposed. With such a configuration, it is possible to operate the blocking mechanism 109 by using the mechanical key 100 .

(4) The blocking mechanism 109 has an operation portion 929 . When the operating portion 929 moves in a predetermined direction, the worm wheel 82 separates from the gear 15 . According to such a configuration, the engagement between the worm wheel 82 and the gear 15 can be released simply by moving the operating portion 929 .

(Modification)
(1) In the above description, the configuration in which the opening/closing type cover 150 is opened by the mechanical key 100 has been described as an example, but the configuration is not limited to this. For example, the following configuration may be used.

An openable cover 150 is configured to be openable and closable without a mechanical key 100. - 特許庁Instead, the blocking mechanism 109 is configured so that it cannot be operated without the mechanical key 100 . That is, the mechanical key 100 is configured so that the blocking mechanism 109 can be operated (specifically, the link mechanism 92A shown in FIG. 11 can be operated). Such a configuration also provides the same effects as the electronic bicycle lock 1A described above.

(2) The motor 4 rotates in the forward direction to move the bolt 3 to the unlocked position, and rotates in the reverse direction to move the bolt 3 to the locked position. may be configured.

(3) In the electronic bicycle lock 1A described above, similar to the electronic bicycle lock 1 of the first embodiment, the configuration in which the bolt 3 has the tooth grooves 31 has been described as an example. In other words, the configuration in which the bolt 3 directly meshes with the gear 15 has been described as an example. However, it is not limited to this.

The bolt 3 does not necessarily have to have the tooth spaces 31 . That is, the bolt 3 may not have the tooth grooves 31 formed therein. Alternatively, the bolt 3 may be connected to another gear component (not shown), and the gear component may mesh with the gear 15 .

In the case of such a configuration, as the gear 15 rotates, the bolt 3 rotates together with the gear component. Such a configuration also provides the same effects as the electronic bicycle lock 1A described above.

It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the meaning and range of equivalents of the scope of the claims.
