Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to fig. 1. The dimensions of the components in the drawings do not necessarily faithfully represent actual dimensions of the components, dimensional ratios of the components, and the like.
In the following description, the front, rear, left, and right directions refer to the front, rear, left, and right directions as viewed from a driver seated on the seat 24 of the electric assist bicycle while holding the handlebar 23.
First, an electric assist bicycle in which a bicycle lock system according to an embodiment of the present invention is mounted will be described.
< integral Structure of electric assist bicycle >
As shown in fig. 1, the electric assist bicycle 1 has pedals 33, 34 and an electric motor 60. The electric assist bicycle 1 is driven by a driving torque obtained by adding up a pedal torque generated when the driver steps on the pedals 33 and 34 and a motor torque output from the electric motor 60. The motor torque of the electric motor 60 becomes an assist torque for assisting the stepping operation of the pedals 33 and 34 by the driver.
The electric assist bicycle 1 has a body frame 11 extending in the front-rear direction. The electric assist bicycle 1 includes a front wheel 21, a rear wheel 22, a handlebar 23, a seat 24, and a power unit 40.
The vehicle body frame 11 includes a head pipe 12, a lower frame 13, a seat frame 14, a pair of lower forks (chain stay)16, and a pair of upper forks (seat stay) 17. The head pipe 12 is disposed at the front portion of the electric assist bicycle 1. The head pipe 12 is connected to a front portion of a lower frame 13 extending rearward. The seat frame 14 is connected to the rear portion of the lower frame 13. The seat frame 14 extends obliquely rearward and upward from a rear end portion of the lower frame 13.
The handle stem 25 is rotatably inserted into the head pipe 12. A handle 23 is fixed to an upper end of the handle stem 25. A front fork 26 is fixed to a lower end portion of the handle stem 25. The front wheel 21 is rotatably supported by an axle 27 at a lower end portion of the front fork 26. A front wheel speed sensor 37 for detecting a vehicle speed from the rotation of the front wheel 21 is provided at a lower end portion of the front fork 26.
A seat tube 28 is inserted into the inside of the cylindrical seat frame 14. A seat 24 is provided at an upper end portion of the seat tube 28.
The pair of bottom forks 16 are provided so as to sandwich the rear wheel 22 from the left and right. A pair of lower forks 16 extend from the rear portion of the lower frame 13 toward the center of rotation of the rear wheel 22. A pair of upper forks 17 extends from an upper portion of the seat frame 14 toward the center of rotation of the rear wheel 22. The rear wheel 22 is rotatably supported at the rear end portions of the lower fork 16 and the upper fork 17.
A battery 35 for supplying electric power to the electric motor 60 of the power unit 40 is disposed behind the seat frame 14. The battery 35 includes a chargeable/dischargeable secondary battery and a battery control unit, not shown. The battery control unit controls charging and discharging of the secondary battery, and monitors an output current, a remaining capacity, and the like.
The power unit 40 is assembled and unitized by a crankshaft 41, a crank output shaft (not shown), a drive sprocket 42, a pedal torque detection portion 57, a crank rotation detection portion 58, an electric motor 60, and an auxiliary sprocket 44 in a unit case 50. The power unit 40 is coupled to the vehicle body frame 11 by bolts.
The crank shaft 41 is rotatably provided below the seat frame 14. The crank shaft 41 is supported by the unit case 50 so as to penetrate in the left-right direction. Crank arms 31 and 32 are attached to both ends of the crank shaft 41. Pedals 33 and 34 are rotatably attached to the front ends of the crank arms 31 and 32. The pedal torque detection portion 57 detects pedal torque input to the crankshaft 41 by the driver via the pedals 33, 34. The crank rotation detecting unit 58 detects the rotation of the crankshaft 41 when the driver rotates the pedals 33 and 34. The crank output shaft (not shown) is formed in a cylindrical shape coaxial with the crank shaft 41, and is connected to the crank shaft 41 via a one-way clutch (not shown).
The drive sprocket 42 is attached to the right end of a crank output shaft (not shown). The drive sprocket 42 rotates together with the crank shaft 41. The driven sprocket 45 is disposed coaxially with the rear wheel shaft 29 of the rear wheel 22. The driven sprocket 45 is coupled to the rear wheel 22 via a one-way clutch not shown.
An endless chain 46 is stretched over the drive sprocket 42 and the driven sprocket 45. Thus, when the driver steps on the pedals 33, 34, the drive sprocket 42 rotates. The rotation of the drive sprocket 42 is transmitted to the driven sprocket 45 via the chain 46, and the rear wheel 22 is driven.
The electric motor 60 is disposed in the unit case 50 and behind the crank shaft 41. An auxiliary sprocket 44 is provided on an output shaft of the electric motor 60. Electric power is supplied from the battery 35 to the electric motor 60. When electric power is supplied to the electric motor 60, the electric motor 60 rotates. The rotation of the electric motor 60 is transmitted to the chain 46 via the auxiliary sprocket 44. Thus, when electric power is supplied to the electric motor 60, motor torque is generated in the electric motor 60. The motor torque is transmitted to the rear wheel 22 via the chain 46.
Handle portions 63 are provided at the left and right end portions of the handlebar 23. The handle portion 63 extends in a substantially front-rear direction. The driver can hold these handle portions 63.
A brake lever 65 is provided near the handle portion 63. When the driver operates the right brake lever 65 with the right hand, a braking force is applied to the front wheel 21. When the driver operates the left brake lever 65 with the left hand, a braking force is applied to the rear wheel 22.
In the electric assist bicycle 1, the control device 100 controls the electric motor 60 to apply a motor torque to the rear wheel 22.
Fig. 2 is a block diagram showing the functions of the electric assist bicycle 1. As shown in fig. 2, the control device 100 includes a pedal torque calculation unit 101, a motor control unit 95, a motor drive unit 105, a transmission stage estimation unit 97, and a memory 98.
< Transmission route of Power >
Next, the power transmission path will be described.
When the driver steps on the pedals 33 and 34 to rotate the crankshaft 41, the rotation of the crankshaft 41 is transmitted to the chain 46 via the one-way clutch 55. The one-way clutch 55 transmits only the forward rotation of the crankshaft 41 to the chain 46, and the reverse rotation of the crankshaft 41 is not transmitted to the chain 46.
The rotation of the chain 46 is transmitted to the driven sprocket 45 on the rear wheel 22 side. The rotation of the driven sprocket 45 is transmitted to the rear wheel 22 via the speed change mechanism 91 and the one-way clutch 92.
The transmission mechanism 91 is a mechanism capable of changing a shift stage in accordance with a shift operation device 93 operated by a driver. The one-way clutch 92 transmits the rotation of the driven sprocket 45 to the rear wheel 22 only when the rotational speed of the driven sprocket 45 is faster than the rotational speed of the rear wheel 22. When the rotational speed of the driven sprocket 45 is slower than the rotational speed of the rear wheel 22, the one-way clutch 92 does not transmit the rotation of the driven sprocket 45 to the rear wheel 22.
The rotation of the electric motor 60 is transmitted to the one-way clutch 85 via the speed reducer 82. The one-way clutch 85 transmits only the rotation of the speed reducer 82 in the direction of forward rotation of the chain 46 to the chain 46, and does not transmit the rotation of the speed reducer 82 in the direction of reverse rotation of the chain 46 to the chain 46.
Thus, in the electric assist bicycle 1 according to the present embodiment, the pedal torque input to the crank shaft 41 and the motor torque of the electric motor 60 are combined by the chain 46.
< Path of Signal >
Next, the path of the signal will be described.
When the driver rotates the crank shaft 41, a pedal torque detection portion 57 provided in the vehicle generates a signal corresponding to the pedal torque input to the crank shaft 41. The pedal torque detection unit 57 inputs the signal to the pedal torque calculation unit 101.
The pedal torque calculation unit 101 converts the signal from the pedal torque detection unit 57 into pedal torques applied to the pedals 33 and 34 by the driver. The pedal torque calculation unit 101 inputs the value of the pedal torque to the motor control unit 95.
The crank rotation detecting unit 58 is a sensor that detects the phase of the crankshaft 41. The crank rotation detecting portion 58 generates a signal corresponding to the phase of the crankshaft 41. The crank rotation detecting unit 58 inputs the signal to the motor control unit 95.
The front wheel speed sensor 37 transmits a signal of the rotation speed of the front wheel 21 to the gear shift stage estimating section 97. The gear stage estimation unit 97 estimates a gear stage from the rotation speed of the front wheel 21, and transmits the information to the motor control unit 95.
The electric motor 60 is provided with a motor rotation sensor 99. The motor rotation sensor 99 detects the rotation speed of the motor 60 and transmits the rotation speed to the gear shift stage estimating unit 97 and the motor driving unit 105.
The motor control unit 95 calculates a command value for giving an appropriate assist force by a control method described later, and transmits the command value to the motor drive unit 105.
The motor drive unit 105 supplies electric power corresponding to the command value from the battery 35 to the electric motor 60 based on the command value from the motor control unit 95. Thereby, the electric motor 60 supplied with electric power is driven to generate a predetermined motor torque.
< first embodiment >
Fig. 3 is a block diagram of a bicycle lock system 200 in accordance with a first embodiment of the present invention. As shown in fig. 3, the bicycle lock system 200 includes: a portable radio wave transmitting device 210 capable of transmitting a radio wave, and a loop lock 220.
The ring lock 220 is a device mounted on the electric assist bicycle 1. The ring lock 220 can lock the rear wheel 22. The loop lock 220 includes a receiving unit 221, a control unit 222, a lock unit 223, and a response unit 224. The lock portion 223 is a portion capable of locking the rear wheel 22.
The lock portion 223 includes a latch movable between the spokes of the rear wheel 22 and an electric actuator such as a motor for moving the latch. The latch is made to interfere with the spokes so that the rear wheel 22 cannot rotate, whereby the lock portion 223 locks the rear wheel 22. The response unit 224 is composed of a lamp and a buzzer. In the present embodiment, the response unit 224 can emit light and sound.
The receiver 221 is configured to be able to always receive radio waves. The receiving unit 221 can receive the radio wave even when the electric assist bicycle 1 is not in a state in which the assist torque can be applied. That is, the receiving unit 221 can receive the radio wave even when the user does not turn ON (ON) the power assist function. The receiving unit 221 of the present embodiment is supplied with electric power from the battery 35 mounted on the electric assist bicycle 1. In addition, when the bicycle lock system 200 is mounted on a bicycle without an electric assist function, the bicycle lock system 200 may be configured to include a battery.
The control unit 222 can transmit an unlocking operation signal to the lock unit 223. When the lock 223 receives an unlocking action signal, the actuator acts to move the latch from a position between the spokes to a position where it does not interfere with the spokes. The locking operation may be performed electrically or manually by a user operating a key.
The control unit 222 can transmit a response operation signal to the response unit 224. When the response unit 224 receives the response operation signal, the response unit 224 causes the lamp to emit light, and further, the buzzer sounds. In the following description, the case where the response unit 224 emits light and generates sound is referred to as operating the response unit 224.
Fig. 4 is a schematic view of a radio wave transmitting device 210 used in the bicycle lock system 200 according to the first embodiment of the present invention. As shown in fig. 3 and 4, the radio wave transmitting device 210 of the present embodiment includes a response operation unit 211 and an unlock operation unit 212. When the response operation unit 211 is operated, the radio wave transmitting device 210 transmits a response radio wave. When the unlocking operation unit 212 is operated, the radio wave transmitting device 210 transmits an unlocking radio wave. The unlocking radio wave and the response radio wave contain unique identification information in each bicycle lock system 200. The loop lock 220 is configured to be unlocked only by an unlocking radio wave including specific identification information, and is configured not to operate the response unit 224. The response radio wave is a radio wave including a signal for operating the control unit 222 with respect to the response unit 224. The unlocking radio wave is a radio wave including a signal for causing the control unit 222 to unlock the lock section 223.
As shown in fig. 4, the radio wave transmitting device 210 of the present embodiment includes a response operation unit 211 and an unlock operation unit 212. In the illustrated example, the button constituting the unlocking operation portion 212 is larger than the button constituting the response operation portion 211. Thus, even when the user operates the radio wave transmitting device 210 in the dark, the unlocking operation portion 212 and the response operation portion 211 can be operated without being mistaken. Thus, the response operation portion 211 and the unlock operation portion 212 are preferably configured to: at least one of the shape, size, color, unevenness, and the like is different.
Fig. 5 shows a flowchart executed by the control unit 222 of the bicycle lock system 200 according to the present embodiment. The control unit 222 periodically repeats the processing shown in fig. 5. As shown in fig. 5, first, the control unit 222 determines whether the receiving unit 221 has received any one of the unlocking radio wave and the response radio wave (step S01). If no electric wave is received (no in step S01), the control section 222 ends the process.
When it is determined that any one of the radio waves is received by the receiving unit 221 (yes in step S01), the control unit 222 determines whether or not the received radio wave is a response radio wave (step S02).
If the received radio wave is a response radio wave (yes in step S02), the control unit 222 transmits a response operation signal to the response unit 224 to operate the response unit 224 (step S03), and the process ends.
If the received radio wave is not a response radio wave but an unlocking radio wave (no in step S02), control unit 222 transmits an unlocking operation signal to lock portion 223 to unlock lock portion 223 (step S04), and the process ends.
Fig. 6 is a diagram showing a relationship between the distance between the receiving unit 221 and the radio wave transmitting device 210 of the electric assist bicycle 1 and the reception intensity of the radio wave in the receiving unit 221. In the present embodiment, the output intensity of the unlocking radio wave is smaller than the output intensity of the response radio wave. The radio wave transmitting device 210 outputs the unlock radio wave at a lower intensity than the response radio wave. When the radio wave is separated from a position close to the transmission source, the reception intensity sharply decreases, and gradually decreases as the distance increases. The radio wave attenuates roughly in proportion to the square of the distance. On the other hand, the receiving unit 221 can detect only radio waves having a certain intensity or more. That is, the receiving unit 221 has a detection limit, which is the minimum intensity that can be detected.
Therefore, as shown in fig. 6, even at a point distant from the radio wave transmitting device 210 by the distance RA, the receiving unit 221 can detect a response radio wave having a large output intensity. On the other hand, the receiver 221 cannot detect an unlock radio wave with a small output intensity at a point distant from the radio wave transmitting device 210 by the distance RA. That is, the distance at which the receiver 221 can detect the unlocking radio wave becomes the distance RB shorter than the distance RA. In fig. 6, the distance RA represents the distance between the radio wave transmitting device 210 and the receiving unit 221 at which the reception intensity of the response radio wave becomes the detection limit. The distance RB indicates the distance between the radio wave transmitting device 210 and the receiving unit 221 at which the reception intensity of the unlocking radio wave becomes the detection limit. The distance 0 to RB [ m ] is a distance that enables unlocking, and the distance 0 to RA [ m ] is a distance that enables the response unit 224 to operate.
Thus, in the bicycle lock system 200 according to the present embodiment, the radio wave transmitting device 210 outputs the unlocking radio wave at a lower intensity than the response radio wave. Therefore, even when the user erroneously operates the lock release operation portion 212 at a position distant from the electric assist bicycle 1, the lock release radio wave is not detected by the receiving portion 221, and the lock release portion 223 is not unlocked by the control portion 222. On the other hand, the response unit 224 is a unit that the user wants to operate when he or she does not know the exact position of the electric assist bicycle 1. Since the response radio wave is output at a greater intensity than the unlock radio wave, the user can confirm the position of the electric assist bicycle 1 from a distance, and the user's convenience is ensured.
Therefore, even when a malicious third person approaches the electric assist bicycle 1 of the user, the lock can be unlocked only when the user approaches the electric assist bicycle 1 of the user, and thus the protection performance is improved.
Preferably, the radio wave transmitting device 210 outputs the unlock radio wave at such an intensity that the reception intensity of the unlock radio wave transmitted at a point closer than 5m from the electric assist bicycle 1 becomes equal to or higher than the detection limit of the receiving unit 221, and outputs the response radio wave at such an intensity that the reception intensity of the response radio wave transmitted at a point 30m away from the electric assist bicycle 1 becomes equal to or higher than the detection limit of the receiving unit 221. That is, it is preferable that the distance RA be 30m or more and the distance RB be 5m or less.
More preferably, the radio wave transmitting device 210 outputs the unlocking radio wave at such an intensity that the reception intensity of the unlocking radio wave transmitted at a point closer than 3m from the electric assist bicycle 1 becomes equal to or higher than the detection limit of the receiving unit 221. Preferably, the radio wave transmitting device 210 outputs the response radio wave at such an intensity that the reception intensity of the response radio wave transmitted from the electric assist bicycle 1 at a location 20m away becomes equal to or higher than the detection limit of the receiving unit 221. That is, it is more preferable that the distance RA be 20m or more and the distance RB be 3m or less.
More preferably, the radio wave transmitting device 210 outputs the unlocking radio wave at such an intensity that the reception intensity of the unlocking radio wave transmitted at a point closer than 1m from the electric assist bicycle 1 becomes equal to or higher than the detection limit of the receiving unit 221. Preferably, the radio wave transmitting device 210 outputs the response radio wave at such an intensity that the reception intensity of the response radio wave transmitted from the electrically assisted bicycle 1 at a location 10m away becomes equal to or higher than the detection limit of the receiving unit 221. That is, it is more preferable that the distance RA be 10m or more and the distance RB be 1m or less.

As shown in fig. 7, a bicycle lock system 300 according to a second embodiment of the present invention includes a radio wave transmitting device 310 having a single remote control operation unit 311. As shown in fig. 8, the radio wave transmitting device 310 includes an operation determination unit 312. The remote operation unit 311 is configured to be operable by one push (first operation) and two pushes (second operation). When pressed, the remote operation unit 311 outputs an operation signal to the operation determination unit 312.
For example, when the operation determination unit 312 determines that a signal is input from the remote control unit 311 once (only the signal is input and the input is lost) within a certain time period from the operation of the remote control unit 311, it determines that the remote control unit is pressed once. The operation determination unit 312 determines that the remote operation unit is pressed twice when a signal is input twice from the remote operation unit 311 within a certain time period after the remote operation unit 311 is operated (the signal is input, the input is lost, and the signal is input again).
As shown in fig. 8, in the bicycle lock system 300 of the present embodiment, the radio wave transmitting device 310 includes a remote control operation unit 311 and an operation determination unit 312. As described above, the operation determination unit 312 determines whether the remote operation unit 311 is pressed once or twice. If operation determination unit 312 determines that remote control unit 311 is pressed once, radio wave transmitting device 310 outputs an unlocking radio wave. If operation determination unit 312 determines that remote control unit 311 is pressed twice, radio wave transmitting device 310 outputs a response radio wave.
In the present embodiment, the radio wave transmitting device 310 may output the unlock radio wave at a lower intensity than the response radio wave. Therefore, as in the first embodiment described above, the user convenience can be ensured and the protection performance can be improved. Further, according to the present embodiment, the user can select whether to operate the response unit 224 or to unlock the lock simply by operating the single remote operation unit 311 with different operations, thereby further improving convenience.
In addition, in the present embodiment, one pressing and two pressing are cited as the first operation and the second operation, but the present invention is not limited to this. One press may be set as the second operation and two presses may be set as the first operation. The two-time pressing may be a plurality of times of pressing more than two times. Alternatively, the remote control operation unit 311 may be operated by half-pressing or full-pressing (full stroke), and different radio waves may be output according to the respective operations. Alternatively, the remote control operation unit 311 may be operated by a long press and a short press, and different radio waves may be output according to the respective operations.
In the present embodiment, an example in which the operation determination unit 312 electrically determines the first operation and the second operation of the remote operation unit 311 has been described, but the present invention is not limited to this. For example, the remote control operation unit 311 may be configured to be tiltable in the right and left directions. In this case, the configuration may be: when the remote control unit 311 is tilted to the right, the remote control unit 311 is brought into conduction with the right contact to transmit an unlocking radio wave, and when the remote control unit 311 is tilted to the left, the remote control unit is brought into conduction with the left contact to transmit a response radio wave. Thus, the first operation and the second operation can be mechanically performed, and the unlocking radio wave and the response radio wave can be mechanically distinguished from each other to transmit the signal.
In the present embodiment, the radio wave transmitting apparatus 310 has been described as including the single remote control unit 311, but the present invention is not limited to this example. The radio wave transmitting device 310 may include a remote control unit 311 capable of outputting other radio waves, a remote control unit 311 in which a physical key appears during operation, and the like, in addition to the remote control unit 311 that outputs a response radio wave or an unlock radio wave when operated.
< third embodiment >
In the first and second embodiments described above, the radio wave transmitters 210 and 310 have been described as examples of transmitting two types of radio waves, i.e., the unlock radio wave and the response radio wave, but the present invention is not limited to this example. The third embodiment of the present invention includes a single remote control unit 311, as in the second embodiment shown in fig. 7. In the present embodiment, the configuration is such that: when the remote control operation unit 311 is operated, the radio wave transmitting device 310 transmits a single type of radio wave. The radio wave transmitting device 310 of the present embodiment does not transmit two types of radio waves, i.e., the unlock radio wave and the response radio wave, as in the first and second embodiments described above.
Fig. 9 is a flowchart of a bicycle lock system 300 in accordance with a third embodiment of the present invention. As shown in fig. 9, the control unit 222 first determines whether the reception unit 221 has received the radio wave transmitted from the radio wave transmission device 310 (step S11). If it is determined that the reception unit 221 has not received the radio wave (no in step S11), the control unit 222 ends the process.
If it is determined that the reception unit 221 has received the radio wave (step S11: yes), the control unit 222 determines whether or not the intensity of the received radio wave is equal to or higher than a predetermined value (step S12). When the intensity of the radio wave is equal to or higher than the predetermined value (yes in step S12), controller 222 transmits an unlocking operation signal to lock portion 223 to unlock lock portion 223 (step S13). The predetermined value here is an intensity greater than the detection limit of the receiving unit 221.
When the intensity of the radio wave is smaller than the predetermined value (NO in step S12), the control unit 222 transmits a response operation signal to the response unit 224 to operate the response unit 224 (step S14).
Fig. 10 is a diagram showing a relationship between a radio wave emitted from the radio wave transmitting device 310 of the present embodiment and a distance. In the present embodiment, the distance between the radio wave transmission device 310 and the reception unit 221 when the reception unit 221 receives the radio wave transmitted from the radio wave transmission device 310 at the intensity of the detection limit is set to the maximum distance RC at which the response unit 224 can operate. The arbitrary intensity above the detection limit is set to the predetermined value determined in step S12. The distance at this time is set as the unlocking limit distance RD. That is, in fig. 10, the distance 0 to RD [ m ] is a distance at which the lock can be unlocked, and the distances RD to RC are distances at which the response unit 224 can operate.
In the present embodiment, when the user approaches the electric assist bicycle 1 of the user, the remote control operation unit 311 is operated, and when the radio wave is output, any one of unlocking and operating the response unit 224 is performed according to the distance between the radio wave transmitting device 310 and the receiving unit 221.
The intensity of the electric wave attenuates as the distance increases. Therefore, the lock is unlocked when the reception intensity of the radio wave is equal to or greater than the predetermined value, that is, when the radio wave transmitting device 310 is within the predetermined distance from the user's electric assist bicycle 1, and the response unit 224 is operated when the radio wave transmitting device 310 is away from the user's electric assist bicycle 1 by the predetermined distance. Therefore, even when a malicious third person is located near the electric assist bicycle 1 of the user or when the remote operation unit 311 is operated from a position away from the user, if the user is further away than the predetermined distance, only the response unit 224 operates and the lock is not unlocked, so that the safety is improved.
< fourth embodiment >
Fig. 11 is a flowchart of a bicycle lock system according to a fourth embodiment of the present invention. The present embodiment includes a single remote control unit 311 as in the third embodiment. In the present embodiment, the configuration is such that: when the remote control operation unit 311 is operated, the radio wave transmitting device 310 transmits a single type of radio wave for a fixed time.
As shown in fig. 11, steps S21 to S24 of the present embodiment are the same as steps S11 to S14 of the third embodiment. In the present embodiment, after the response unit 224 is operated, the control unit 222 determines whether or not the reception unit 221 continues to receive the radio wave (step S25). If the reception of the radio wave is not continued (no in step S25), control unit 222 ends the process.
If the reception of the radio wave is continued (step S25: YES), the control section 222 judges whether or not the reception intensity is equal to or higher than a predetermined value (step S26). If the reception intensity is equal to or higher than the predetermined value (yes in step S26), control unit 222 transmits an unlocking operation signal to lock 223 to unlock lock 223 (step S23). If the reception intensity is not greater than the predetermined value (no in step S26), control unit 222 returns to the process of determining whether or not to continue the radio wave (step S25).
In step S26, if the user moves the response unit 224 sufficiently close to the electric assist bicycle 1, the user can unlock the lock without any special operation, which improves convenience.
< fifth embodiment >
In the third embodiment, the radio wave transmitting apparatus 310 is described as an example in which the radio wave is transmitted when the remote control operation unit 311 is operated, but the present invention is not limited to this example.
The fifth embodiment differs from the third embodiment only in that the remote control operation unit 311 is configured to always transmit radio waves. With such a configuration, the response unit 224 automatically operates when the user approaches the electric assist bicycle 1 at a distance where the reception intensity of the radio wave at the receiver 221 is equal to or higher than the detection limit of the receiver 221 and lower than a predetermined value. When the user approaches the electric assist bicycle 1 until the reception intensity reaches a distance equal to or greater than a predetermined value, the lock 223 is automatically unlocked. The user only needs to carry the radio wave transmitting device 310 without any operation, and convenience is further improved.
< sixth embodiment >
Next, a bicycle lock system 400 according to a sixth embodiment of the present invention will be described with reference to fig. 12 and 13. Fig. 12 is a block diagram of a bicycle lock system 400 in accordance with a sixth embodiment of the present invention. Fig. 13 is a flowchart of a bicycle lock system 400 in accordance with a sixth embodiment of the present invention.
As shown in fig. 12, in the present embodiment, the radio wave transmitting device 410 includes a remote control operation unit 411 and a ranging radio wave transmitting unit 412. The remote control operation unit 411 transmits a control radio wave when operated. The ranging radio wave transmitting unit 412 always transmits a ranging radio wave. The control unit 222 can calculate the distance between the receiving unit 221 and the radio wave transmitting device 410 from the reception intensity of the ranging radio wave received by the receiving unit 221. The control radio wave is a radio wave including the following signals: the signal is used to operate the controller 222 with respect to the response unit 224 or the lock unit 223. The control radio wave is transmitted when the remote control operation unit 411 is operated. The ranging radio wave is a radio wave including the following signals: this signal is used to detect the separation distance between the radio wave transmitting device 410 and the receiving unit 221.
The control unit 222 repeatedly executes the processing shown in fig. 13 at predetermined time intervals. As shown in fig. 13, first, the control unit 222 determines whether or not the control radio wave is received by the reception unit 221 (step S31). If it is determined that the control electric wave has not been received (no in step S31), control unit 222 ends the process.
When it is determined that the control radio wave is received (yes in step S31), the control unit 222 determines whether or not the reception intensity of the ranging radio wave is equal to or higher than a predetermined value (step S32).
If the reception intensity of the ranging radio wave is equal to or higher than the predetermined value (yes in step S32), control unit 222 transmits an unlocking operation signal to lock portion 223 to unlock lock portion 223 (step S33). When the reception intensity of the ranging radio wave is equal to or greater than the predetermined value, the radio wave transmitting device 410 is located within a predetermined distance from the receiving unit 221. Therefore, if the reception intensity of the ranging radio wave is equal to or greater than the predetermined value, the lock section 223 is unlocked.
If the reception intensity of the ranging radio wave is less than the predetermined value (NO in step S32), the control unit 222 transmits a response operation signal to the response unit 224 to operate the response unit 224 (step S34). When the reception intensity of the ranging radio wave is smaller than the predetermined value, the radio wave transmitting device 410 is located farther than the predetermined distance from the receiving unit 221. Therefore, if the reception intensity of the ranging radio wave is less than the predetermined value, the lock 223 is not unlocked, and the response unit 224 is operated to notify the user of the position of the electric assist bicycle 1.
Thus, in the bicycle lock system 400 according to the present embodiment, the control unit 222 operates the response unit 224 when the control radio wave is received and the distance measurement radio wave is received by the reception unit 221 with a reception intensity smaller than the predetermined value. When the control radio wave is received, the control unit 222 unlocks the lock unit 223 when the reception unit 221 receives the ranging radio wave with a reception intensity equal to or higher than a predetermined value.
In the bicycle lock system 400 according to the present embodiment, as in the above-described embodiments, the response unit 224 is operated when the user is located at a position away from the electric assist bicycle 1, and the user can unlock the bicycle when the user comes to an approaching position, which is highly convenient and highly preventive.
In the bicycle lock system 400 according to the present embodiment, the radio wave transmitting device 410 always transmits the ranging radio wave. Therefore, the reception unit 221 can receive the ranging radio wave before receiving the control radio wave. Therefore, when the receiving unit 221 receives the control radio wave, the distance to the radio wave transmitting device 410 can be immediately calculated, and it is possible to quickly determine whether to unlock the lock 223 or to operate the response unit 224. Further, since the ranging radio wave is always transmitted, the accuracy of the separation distance can be improved by calculating the separation distance from the average value of the reception intensity.
< seventh embodiment >
Next, a bicycle lock system 500 according to a seventh embodiment of the present invention will be described with reference to fig. 14 and 15. Fig. 14 is a block diagram of a bicycle lock system 500 according to a seventh embodiment of the present invention. Fig. 15 is a flowchart of a bicycle lock system 500 according to a seventh embodiment of the present invention.
As shown in fig. 14, in the bicycle lock system 500 according to the present embodiment, the radio wave transmitting device 510 includes a remote control operation unit 511, and the remote control operation unit 511 transmits a radio wave for a predetermined time period when operated. The radio wave transmitting device 510 is configured to: when the remote control operation unit 511 is operated, the radio wave is transmitted for about 1 to 30 seconds.
The control unit 222 repeatedly executes the processing shown in fig. 15 all the time. As shown in fig. 15, first, the control unit 222 determines whether or not the radio wave is received by the reception unit 221 (step S41). When the control unit 222 determines that the radio wave has not been received by the reception unit 221 (no in step S41), it ends the process.
If it is determined that the radio wave is received by the receiver 221 (step S41: YES), the controller 222 transmits a response operation signal to the response unit 224 to operate the response unit 224 (step S42).
Further, the control unit 222 determines whether or not the reception intensity of the radio wave in the reception unit 221 is equal to or higher than a predetermined value (step S43). When the reception intensity of the radio wave is equal to or higher than the predetermined value (yes in step S43), control unit 222 transmits an unlocking operation signal to lock portion 223 to unlock lock portion 223 (step S45).
When the reception intensity of the radio wave is not greater than the predetermined value (no in step S43), the control unit 222 determines whether or not the radio wave is received (step S44). If the electric wave is not received (no in step S44), control unit 222 ends the process. If the radio wave is received (step S44: YES), the control section 222 determines again whether or not the reception intensity of the radio wave is equal to or greater than a predetermined value (step S43).
Thus, in the present embodiment, the radio wave transmitting device 510 is configured to transmit the radio wave for a predetermined time after the remote control operation unit 511 is operated, and the control unit 222 operates the response unit 224 regardless of the reception intensity after the reception unit 221 receives the radio wave, and unlocks the lock unit 223 when the reception intensity reaches a predetermined value or more before the predetermined time elapses.
For example, assume that the predetermined value in step S43 is set to the reception intensity when a radio wave emitted from a position spaced apart by a distance of 3m is received. The radio wave transmitting device 510 is configured to transmit radio waves within 30 seconds. At this time, when the user holds the radio wave transmitting device 510 and operates the remote control operation unit 511 at a position 5m away from the electric assist bicycle 1, the radio wave is emitted within 30 seconds. The control unit 222 first detects the radio wave and operates the response unit 224. While the user operates the remote control operation unit 511 to transmit the radio wave, the control unit 222 unlocks the lock portion 223 when the user reaches a position 3m away from the electric assist bicycle 1. On the other hand, when the user does not find his or her electric assist bicycle 1 and does not approach the electric assist bicycle 1 within 3m even after 30 seconds, the control unit 222 does not unlock the lock portion 223.
The predetermined value in step S44 is preferably set to the reception intensity when receiving radio waves emitted from positions spaced at distances of 1-5 m. The predetermined value in step S44 is more preferably set to the reception intensity when the radio wave emitted from a position spaced 2 to 4m apart is received. The predetermined value in step S44 is preferably set to a reception intensity when receiving radio waves emitted from positions spaced at a distance of 1 to 5 m.
The time for which the radio wave transmitting device 510 continues to transmit the radio wave is preferably set within a range of 3 to 60 seconds. The time for which the radio wave transmitting device 510 continues to transmit the radio wave is more preferably set to 5 to 30 seconds.
In the bicycle lock system 500 according to the present embodiment, as in the above-described embodiments, when the user is located at a position away from the electric assist bicycle 1, the response unit 224 is operated, and when the user comes to an approaching position, the lock can be unlocked, which is highly convenient and highly preventive.
Further, according to the bicycle lock system 500 of the present embodiment, the user can automatically unlock the lock portion 223 only by approaching the electric assist bicycle 1 after operating the response portion 224 of the electric assist bicycle 1 of the user by operating the remote control operation portion 511, and thus the convenience is further improved.
< modification example >
Next, a modified example of the present invention will be described. In this modification, the radio wave transmitting apparatus includes a remote control operation unit that emits radio waves when operated, as in the first embodiment described above. The loop lock includes a receiving unit, a control unit, a lock unit, and a response unit, which are similar to those of the above-described embodiments.
When the control unit determines that the reception unit has received the radio wave, it transmits a response operation signal to the response unit to operate the response unit. Further, the control unit starts counting t upon receiving the radio wave. The control unit is configured to: when it is determined that the same radio wave is received again before the count t reaches a predetermined time t0, an unlocking operation signal is transmitted to the lock portion to unlock the lock portion.
With this configuration, the user can operate the response unit by operating the remote operation unit once at a position away from the electric assist bicycle, and can unlock the electric assist bicycle by operating the remote operation unit again when the remote operation unit approaches the electric assist bicycle. If the same electric wave is not received even if the count t exceeds the predetermined time t0, the user may leave his or her electric assist bicycle or may simply want to confirm the position of his or her electric assist bicycle. In this case, the lock portion continues to be locked without being unlocked.
< various modifications >
In the above description, the bicycle lock system has been described as being mounted on an electric assist bicycle, but may be mounted on a bicycle that does not have an electric assist function.
In the above description, the bicycle lock system is described by taking as an example the case where the bicycle lock system is configured by a ring lock for locking the rear wheel, but the bicycle lock system may be configured by a lock for locking the front wheel, a Wire lock (Wire lock), or the like.
In the above description, the configuration in which the response unit can emit light and sound has been described, but the present invention is not limited to this. The response unit may be configured to emit one of light and sound. In addition, a headlight or a tail light mounted on the electric assist bicycle may function as a response unit. Alternatively, when the electric assist bicycle includes an assist operation unit, the display unit of the assist operation unit may function as a response unit, and the assist operation unit may include: a switch for starting an assist system for applying assist torque to a wheel or changing an assist mode; and a display unit for displaying the auxiliary mode being executed.
In each of the above embodiments, the control unit may be configured to transmit the response operation signal to the response unit at the same time when the lock unit transmits the unlocking operation signal to the lock unit, and to operate the response unit even when the lock unit is unlocked, so that the lock unit can be unlocked by eye or ear confirmation.
