[0001] This disclosure relates generally to bicycle components other than the rear derailleur and drive unit, a contactless charging system including the bicycle components, and a contactless charging method for charging the bicycle components. [Previous Technology]

[0003] In recent years, some bicycles have been equipped with electric bicycle components or devices to make it easier for riders to operate the bicycle. Examples of such electric bicycle components include suspension, drivetrain (e.g., derailleur, internal gear hub, etc.), and seatpost. These electric bicycle components use power from an internal power source, such as one or more batteries. The power source of the bicycle component needs to be replaced or periodically charged. In cases where the power source of the bicycle component requires periodic charging, the battery is either plugged into a remote charger or removed from the bicycle component and placed on a remote charger.

It will be apparent to those skilled in the art of bicycles from this disclosure that the description of the following embodiments is provided for illustration only and is not intended to limit the invention as defined by the appended claims and their equivalents.

[0081] Referring first to FIG. 1, a first bicycle B1 is shown, equipped with a contactless charging system 10 according to an illustrated embodiment. Bicycle B1 is shown as a road bicycle. However, the contactless charging system 10 can be applied to any other type of bicycle, such as mountain bikes, cross-country bikes, gravel bikes, city bikes, freight bikes, and recumbent bikes. For example, a second bicycle B2 is shown as an electric-assisted bicycle equipped with the contactless charging system 10. Basically, for both the first bicycle B1 and the second bicycle B2, the contactless charging system 10 includes a bicycle assembly BC and a contactless charging device CD. For simplicity, common components or parts of the first bicycle B1 and the second bicycle B2 will be given the same element reference numerals.

[0082] In the contactless charging system 10, a bicycle assembly BC is provided, excluding the rear derailleur and drive unit. In the illustrated embodiment, the bicycle assembly BC is at least one of the following: operating device 12 or 12', adjustable seatpost 14, adjustable suspension 16, adjustable front derailleur 18, light 20, and object retainer 21. The operating device 12 or 12', adjustable seatpost 14, adjustable suspension 16, adjustable front derailleur 18, light 20, and object retainer 21 may be provided to the first bicycle B1 and the second bicycle B2. Therefore, the term "bicycle assembly BC" as used herein generally refers to all bicycle assemblies of the first bicycle B1 and the second bicycle B2 that are part of the contactless charging system 10, including but not limited to the operating device 12, operating device 12', adjustable seatpost 14, adjustable suspension 16, adjustable front derailleur 18, light 20, and object retainer 21. Components or parts of the first bicycle B1 and the second bicycle B2 that are part of the contactless charging system 10 will not be referred to as "bicycle assembly BC".

[0083] The contactless charging device CD can be mounted on a bicycle or is a mobile device carried by the user. For example, as shown in FIG1, the contactless charging device CD includes an external contactless charging device 22 that can be carried by a user (e.g., a rider) and at least one of the battery units 24 installed in each of the first bicycle B1 and the second bicycle B2. Therefore, the term "contactless charging device CD" as used herein refers to all contactless charging devices, including but not limited to the external contactless charging device 22 and battery unit 24 shown in FIG1.

[0084] As shown in Figure 1, the first bicycle B1 includes a frame F supported by a rear wheel RW and a front wheel FW. A front suspension fork FF is pivotally coupled to the frame F at its upper end and rotatably supports the front wheel FW at its lower end. The bicycle B1 also includes a handlebar H, which is mounted to the upper end of the front fork FF for steering the front wheel FW. The rear wheel RW is rotatably mounted to the rear end of the frame F. The seatpost SP is conventionally mounted to the seatpost of the frame F and supports the bicycle seat or saddle S in any suitable manner.

[0085] Conversely, as shown in Figure 2, the second bicycle B2 includes a frame VB supported by a rear wheel RW and a front wheel FW. The frame VB essentially includes a front frame FB and a rear frame RB (swing arm). The frame VB also provides handlebars H. Here, an adjustable suspension 16 is pivotally coupled to the front frame FB at its upper end and rotatably supports the front wheel FW at its lower end. The rear frame RB is pivotally mounted to the rear section of the front frame FB, allowing the rear frame RB to pivot relative to the front frame FB. The rear wheel RW is mounted to the rear end of the rear frame RB. A rear shock absorber RS ​​is operably disposed between the front frame FB and the rear frame RB. The rear shock absorber RS ​​is provided between the front frame FB and the rear frame RB to control the movement of the rear frame RB relative to the front frame FB. That is, the rear shock absorber RS ​​absorbs vibrations transmitted from the rear wheel RW.

[0086] Here, the second bicycle B2 includes an adjustable seatpost 14, which is conventionally mounted to the seat tube of the front frame FB and supports the bicycle seat or saddle S in any suitable manner. Furthermore, here, an adjustable suspension 16 is pivotally mounted to the head tube of the front frame FB. The handlebars H are mounted on the upper end of the adjustable suspension 16. The adjustable suspension 16 absorbs shocks transmitted from the front wheel FW. The adjustable suspension 16 is an electrically adjustable suspension. For example, the stiffness and / or travel length of the adjustable suspension 16 can be adjusted. Although the rear shock absorber RS ​​is not shown as an electrically adjustable suspension, it will be apparent from this disclosure that the rear shock absorber RS ​​may be an adjustable suspension equipped as one of the bicycle components BC of the contactless charging system 10.

[0087] Each of the first bicycle B1 and the second bicycle B2 also includes a drivetrain DT. Here, for example, the drivetrain DT is a chain-driven type, which includes a crank C, at least one front sprocket FS, a plurality of rear sprockets CS, and a chain CN. In the case of the first bicycle B1, the drivetrain DT has a plurality of front sprockets FS. Furthermore, in the case of the first bicycle B1, an adjustable front derailleur 18 is provided on the frame F. The adjustable front derailleur 18 is constructed to the chain CN between the front sprockets FS to respond to an automatic shift signal from the bicycle computer or a shift signal input by the user from the operating device 12 or 12'. Each of the first bicycle B1 and the second bicycle B2 also includes a rear derailleur 26 (i.e., bicycle assembly), which is configured to switch the chain CN between the rear sprockets CS in response to an automatic shift signal from the bicycle speedometer, or a user-input shift signal from the operating device 12 or 12' in the case of the first bicycle B1, or a user-input shift signal from the operating device SL in the case of the second bicycle B2. The crank C includes a crankshaft CA1 and a pair of crank arms CA2. The crankshaft CA1 is rotatably supported to the front frame FB via an electric assist unit E. The crank arms CA2 are provided at opposite ends of the crankshaft CA1. The pedals PD are rotatably coupled to the distal end of each crank arm CA2. Although the drivetrain DT is shown as a chain-driven type drivetrain, the drivetrain DT can be selected from any type of drivetrain and can be belt-driven or shaft-driven.

[0088] The front sprocket FS is provided on the crank C to rotate integrally with the crankshaft CA1. The rear sprocket CS is provided on the hub of the rear wheel RW. The chain CN runs around the front sprocket FS and the rear sprocket CS. The rider applies human driving force to the pedal PD, and the driving force is transmitted to the rear wheel RW through the front sprocket FS, the chain CN and the rear sprocket CS.

[0089] Referring now to FIG. 3, the contactless charging system 10 will now be discussed in more detail. As described above, basically, in each of the first bicycle B1 and the second bicycle B2, the contactless charging system 10 includes at least one bicycle assembly BC (e.g., at least one operating device 12, 12', adjustable seatpost 14, adjustable suspension 16, adjustable front derailleur 18, light 20, and object retainer 21) excluding the rear derailleur and drive unit, and at least one contactless charging device CD (e.g., at least one of external contactless charging device 22 and battery unit 24). Here, each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) includes the basic architecture schematically shown in the block diagram of FIG. 3. Derailleur 18, light 20, and object retainer 21.

[0090] Specifically, each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) includes an electrical component 30, a rechargeable power source 32, and a contactless charging section 34. According to the bicycle assembly BC, the electrical component 30 may be an electric actuator, an electric motor, an electric switch, an electronic controller, a light-emitting element, or any other component that uses electricity. The rechargeable power source 32 is electrically connected to the electrical component 30. Thus, the rechargeable power source 32 is configured to supply power to the electrical component 30. As the electrical component 30 operates, the power of the rechargeable power source 32 is consumed. Therefore, the rechargeable power source 32 needs to be charged during the period when the electrical component 30 is operating. Therefore, the contactless charging section 34 is electrically connected to the rechargeable power source 32, so that the rechargeable power source 32 receives power from the contactless charging section 34.

[0091] Here, each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) also includes a wireless communicator 36, which is configured to communicate with the contactless charging device CD (22, 24). Therefore, each bicycle assembly BC uses the wireless communicator 36 to wirelessly communicate with the contactless charging device CD (22, 24). The wireless communicator 36 of each bicycle assembly BC is also configured to wirelessly communicate with other sensors and / or other components in the bicycle assembly BC. For example, each of the wireless communicators 36 is configured to wirelessly communicate with a forward speed sensor SS. The forward speed sensor SS is mounted on the adjustable suspension 16. The forward speed sensor SS is configured to detect a magnet M mounted on the spokes of the front wheel FW. In this way, the wireless communicator 36 can receive signals indicating the bicycle's riding status. As will be apparent from this disclosure, the wireless communicator 36 can receive other signals indicating the bicycle's riding status from other types of sensors or components. In addition, depending on the bicycle component BC, the wireless communicator 36 can receive control signals and / or other data to assist in the operation of the bicycle component BC.

[0092] Wireless communicator 36 is a hardware device capable of wirelessly transmitting communication signals. As used herein, the term "wireless communicator" includes receiver, transmitter, transceiver, transmitter-receiver, and contemplates any single or combined device or combination of devices capable of transmitting and / or receiving wireless communication signals. The wireless communication signal can be a radio frequency (RF) signal, an ultra-wideband communication signal, ANT+ communication, or Bluetooth communication, or any other type of signal suitable for short-range wireless communication as understood in the field of bicycles. Here, wireless communicator 36 can be a unidirectional or bidirectional wireless communicator, depending on the charging protocol. Preferably, wireless communicator 36 is a bidirectional wireless communicator because it is preferable to exchange information, such as connection, charging, and discharging status, between wireless communicator 36 and contactless charging devices CD (22, 24).

[0093] Furthermore, in the illustrated embodiment, each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) also includes a controller 38. The term "controller" as used herein refers to hardware that executes software programs and excludes human intervention. The controller 38 is preferably an electronic controller that includes a central processing unit (CPU) or a microprocessor unit (MPU). Preferably, the controller 38 includes one or more processors and one or more storage devices. The storage device stores the programs used by the controller 38. The storage device is any computer storage device or any computer-readable medium, with the sole exception of transient propagation signals. For example, the storage device can be non-volatile memory and volatile memory, and may include ROM (read-only memory) devices, RAM (random access memory) devices, hard disks, flash drives, etc.

[0094] In FIG. 3, the contactless charging section 34, the wireless communicator 36, and the controller 38 form a power receiver 40, which is configured to receive power from the contactless charging device CD (22, 24). The contactless charging section 34, the wireless communicator 36, and the controller 38 are shown as separate elements in FIG. 3. However, those skilled in the art of bicycles will recognize from this disclosure that one or more of the contactless charging section 34, the wireless communicator 36, and the controller 38 can be integrated together to perform the activities or functions described herein. For example, in the illustrated embodiment, the wireless communicator 36 and the controller 38 are provided on a common circuit board containing any number of integrated circuits or circuits for performing the activities described herein. Furthermore, although the controller 38 is shown as a single unit located on the circuit board of the power receiver 40, the bicycle components BC (12, 12', 14, 16, 18, 20, 21, 26) are not limited to this architecture. Instead, the controller 38 can be a plurality of controllers provided in different locations.

[0095] As explained later, the controller 38 is also configured to limit the operation of the electrical components 30 when it is determined that the parameters of the charging power supply 32 are outside the allowable range. The controller 38 is also configured to maintain the operation of the electrical components 30 when it is determined that the parameters of the charging power supply 32 are within the allowable range.

[0096] The contactless charging section 34 is configured to wirelessly receive external power and supply it to the charging power source 32. The contactless charging section 34 includes at least a contactless charging coil 34a. This contactless charging coil 34a may include near-field communication (NFC) for use in situations where the contactless charging device CD (e.g., an external contactless charging device 22) can be placed within a few centimeters (approximately 4 cm or less) of the contactless charging coil 34a of a bicycle assembly BC. For example, a rider can use the external contactless charging device 22 to charge and communicate with one of the operating devices 12 or 12' by holding the external contactless charging device 22 close to the operating device 12 or 12'. As used herein, the term "NFC" refers to short-range wireless communication using frequencies in the 13.56 MHz band via electromagnetic induction. Furthermore, contactless charging transmits power via electromagnetic induction using frequencies in the band between approximately 100 kHz and 200 kHz.

[0097] On the other hand, the at least non-contact charging coil 34a can be configured to use magnetic resonance, such that the non-contact charging device CD (22, 24) can be one meter or two meters away from the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). When the non-contact charging coil 34a receives power through magnetic resonance, the wireless communicator 36 is used to communicate information to and from the non-contact charging device CD (22, 24).

[0098] In the illustrated embodiment, each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) further includes an AC-DC converter 42 disposed between the contactless charging section 34 and the charging power supply 32. The AC-DC converter 42 converts the AC power output from the contactless charging section 34 into DC power received by the charging power supply 32. Thus, the DC power output by the AC-DC converter 42 can be used to charge the charging power supply 32.

[0099] In the illustrated embodiment, each bicycle component BC (12, 12', 14, 16, 18, 20, 21, 26) also includes a sensor 44 configured to detect information related to the state of the charging power supply 32. The sensor 44 is configured to communicate with the controller 38 of the power receiver 40. The sensor 44 may be configured to communicate with the controller 38 of the power receiver 40 via wired or wireless communication. By using the sensor 44, the charging of the charging power supply 32 can be improved based on the state of the charging power supply 32.

[0100] Here, sensor 44 includes a temperature sensor 44A configured to detect the temperature of charging power supply 32. The temperature of charging power supply 32 can be used to determine the electrical load on charging power supply 32 and the state of charging power supply 32. Temperature sensor 44A is configured to communicate with controller 38 of power receiver 40. Temperature sensor 44A can be configured to communicate with controller 38 of power receiver 40 via wired or wireless communication. By detecting the temperature of charging power supply 32 using temperature sensor 44A, the electrical load of charging power supply 32 can be determined.

[0101] In the illustrated embodiment, sensor 44 includes voltage sensor 44B, which is configured to detect at least one of the voltage of the charging power supply 32 and the voltage supplied to the charging power supply 32. Voltage sensor 44B is configured to communicate with controller 38 of power receiver 40. Voltage sensor 44B may be configured to communicate with controller 38 of power receiver 40 via wired or wireless communication. Thus, controller 38 can monitor the charging of charging power supply 32. Controller 38 is also configured to monitor at least one of the voltage of charging power supply 32 and the voltage of electrical components after a predetermined period has elapsed since the start of charging. Furthermore, controller 38 is configured to regulate at least one of the voltage supplied to charging power supply 32 and the voltage supplied to electrical components 30.

[0102] The contactless charging devices CD (22, 24) will now be discussed in more detail. Each contactless charging device CD (22, 24) includes a power source 48. The power source 48 can be any type of device that can transmit power to the charging power source 32 of the bicycle components BC (12, 12', 14, 16, 18, 20, 21, 26). For example, the power source 48 may include one or more hydrogen fuel cells, disposable batteries, rechargeable batteries, capacitors, and generators. In the illustrated embodiment, the battery cell 24 (CD) has one or more rechargeable batteries.

[0103] Each contactless charging device CD (22, 24) includes a contactless charging section 50 configured to wirelessly transmit power to the bicycle assembly BC. The contactless charging section 50 includes at least a contactless charging coil 50a. In the case of an external contactless charging device 22, at least the contactless charging coil 50a may include near field communication (NFC) so that a user can place the external contactless charging device 22 within the contactless charging coil 34a of the bicycle assembly BC, which is a few centimeters (about 4 cm or less). In the case of the battery unit 24, at least the contactless charging coil 50a is configured to use magnetic resonance capable of transmitting power over one or two meters. Thus, the charging power source 32 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) can be wirelessly charged on the first bicycle B1 or the second bicycle B2 while the first bicycle B1 or the second bicycle B2 is in motion. Preferably, the contactless charging coil 50a of the external contactless charging device 22 is also configured to use a magnetic resonance capable of transmitting power over one or two meters. Preferably, the contactless charging coil 50a of the contactless charging device CD (22, 24) is configured such that the wirelessly transmitted power can be directed to the contactless charging portion 34 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26).

[0104] In the illustrated embodiment, each contactless charging device CD (22, 24) further includes a wireless communicator 52 for wirelessly communicating with the wireless communicator 36 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). The wireless communicator 52 is a hardware device capable of wirelessly transmitting communication signals to the wireless communicator 36 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). The wireless communication signal can be a radio frequency (RF) signal, an ultra-wideband (UWB) signal, an ANT+ communication signal, or a Bluetooth communication signal, or any other type of signal understood in the bicycle industry suitable for short-range wireless communication. Here, the wireless communicator 52 can be a unidirectional or bidirectional wireless communicator, depending on the charging protocol used with the wireless communicator 36. Preferably, the wireless communicator 52 is a bidirectional wireless communicator because it is preferable to exchange information, such as connection, charging, and discharging status, between the wireless communicator 36 and the wireless communicator 52.

[0105] Furthermore, in the illustrated embodiment, each contactless charging device CD (22, 24) also includes a controller 54. The controller 54 is preferably an electronic controller including a central processing unit (CPU) or a microprocessor unit (MPU). Preferably, the controller 54 includes one or more processors and one or more storage devices. The storage device stores the program used by the controller 54. The storage device can be any computer storage device or any computer-readable medium, with the only exception being transient propagation signals. For example, the storage device can be non-volatile memory and volatile memory, and may include ROM (read-only memory) devices, RAM (random access memory) devices, hard disks, flash drives, etc.

[0106] In the illustrated embodiment, the contactless charging component 50, the wireless communicator 52, and the controller 54 form a power transmitter 60 configured to transmit power to the power receiver 40 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). The contactless charging component 50, the wireless communicator 52, and the controller 54 are shown as separate elements in FIG3. However, those skilled in the art of bicycles will recognize from this disclosure that one or more of the contactless charging component 50, the wireless communicator 52, and the controller 54 can be integrated together to perform the activities or functions described herein. For example, in the illustrated embodiment, the contactless charging component 50, the wireless communicator 52, and the controller 54 are provided on a common circuit board containing any number of integrated circuits or circuits for performing the activities described herein.

[0107] Referring now to Figures 1, 3, and 5, the operating devices 12 and 12' of the first bicycle B1 will be discussed in more detail. Operating devices 12 and 12' are electrical devices for controlling one or more other bicycle components BC (18, 20, 26). For example, operating device 12 may be configured to wirelessly control the light 20 and the rear derailleur 26, while operating device 12 may be configured to wirelessly control the adjustable front derailleur 18 and the light 20. Of course, it will be apparent from this disclosure that the bicycle components controlled by operating devices 12 and 12' are not limited to this particular architecture. Furthermore, operating devices 12 and 12' are also conventionally used as braking control devices.

[0108] Here, the operating device 12 is mounted on the right side of the handlebar H, while the operating device 12' is mounted on the left side of the handlebar H. The operating device 12 is a mirror image of the operating device 12'. Therefore, unless otherwise stated, the following description of the operating device 12 applies to the operating device 12'.

[0109] The operating device 12 mainly includes a base member 62 and an operating lever 64. The operating lever 64 is movably coupled to the base member 62. In this embodiment, the operating lever 64 is pivotally coupled to the base member 62 about a pivot axis P1 to perform braking operations. The operating device 12 also includes a handlebar mounting clamp 66. The base member 62 is conventionally mounted to the handlebar H by means of the handlebar mounting clamp 66. Here, the base member 62 provides a first spatial region SA1, in which the charging power supply 32, the power receiver 40, the AC-DC converter 42, and the sensor 44 are located. However, one or more of the charging power supply 32, the power receiver 40, the AC-DC converter 42, and the sensor 44 may be located in other regions of the spatial region of the operating device 12. For example, the pommel portion of the base member 62 may include a second spatial region SA2 for receiving one or more of the charging power supply 32, the power receiver 40, the AC-DC converter 42, and the sensor 44. In addition, the lever 64 may include a third spatial region SA3 and / or a fourth spatial region SA4 for receiving one or more of the charging power supply 32, the power receiver 40, the AC-DC converter 42, and the sensor 44.

[0110] As described above, electrical components 30 are included in each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). In the case of operating device 12, electrical components 30 include electrical switches configured to output electrical signals to operate external devices. More specifically, in the case of operating device 12, bicycle assembly BC also includes an operating member 68 configured to activate electrical switch 68a. Furthermore, operating device 12 also includes an operating member 70 configured to activate electrical switch 70a. Operating member 70 may provide a fifth spatial region SA5 for receiving one or more of the charging power supply 32, power receiver 40, AC / DC converter 42, and sensor 44. Therefore, in the case of operating device 12, electrical components 30 of operating device 12 include electrical switches 68a and 70a. Charging power supply 32 is electrically connected to electrical switches 68a and 70a to supply power to electrical switches 68a and 70a.

[0111] Here, one of the electrical switches 68a and 70a outputs an upshift signal to the rear derailleur 26, while the other outputs a downshift signal to the rear derailleur 26. The upshift and downshift signals are wirelessly communicated from the wireless communicator 36 of the power receiver 40 (see Figure 3) to the wireless communicator 36 of the rear derailleur 26. Preferably, the wireless communicator 36 of the power receiver 40 of the operating device 12 (see Figure 3) is a two-way wireless communicator capable of both sending and receiving signals.

[0112] Operating members 68 and 70 are movably mounted to operating lever 64, while electrical switches 68a and 70a are fixed to operating lever 64. Therefore, pivoting movement of operating member 68 relative to operating lever 64 causes operating member 68 to activate (depress) electrical switch 68a to operate the external device. Similarly, pivoting movement of operating member 70 relative to operating lever 64 causes operating member 70 to activate (depress) electrical switch 70a to operate the external device. In the illustrated embodiment, the external device corresponds to rear derailleur 26, which operates in response to activation of electrical switches 68a and 70a.

[0113] Here, the operating device 12 also includes an electrical switch 72 and an electrical switch 74 provided on the base member 62. Although the electrical switch 72 is shown as integrated with the operating device 12, the electrical switch 72 is not limited to the illustrated embodiment. The electrical switch 72 may be detached from the operating device 12, for example, mounted on the handlebar H. Here, the user can press the electrical switch 72 and / or the electrical switch 74 to output electrical signals to operate external devices, such as the light 20 and / or some other electronic control components of the first bicycle B1. The electrical components 30 of the operating device 12 include the electrical switches 72 and 74. If the controller 38 of the operating device 12 determines that the parameters (e.g., temperature) of the charging power supply 32 of the operating device 12 are outside the allowable range, the controller 38 of the operating device 12 may then restrict the operating function of one or more of the electrical switches 68a, 70a, 72, and 74 (electrical components 30), such that only certain switches are operable and / or certain functions of these switches are suspended.

[0114] In the case of an operating device 12' having the same physical structure as the operating device 12, electrical switches 68a and 70a are used to control the adjustable front derailleur 18 (BC). In other words, in the case of the operating device 12', one of the electrical switches 68a and 70a outputs an upshift signal to the adjustable front derailleur 18, while the other of the electrical switches 68a and 70a outputs a downshift signal to the adjustable front derailleur 18. The upshift and downshift signals are wirelessly communicated from the wireless communicator 36 of the power receiver 40 (see FIG. 3) to the wireless communicator 36 of the adjustable front derailleur 18. Preferably, the wireless communicator 36 of the power receiver 40 of the operating device 12 (see FIG. 2) is a two-way wireless communicator capable of both transmitting and receiving signals.

[0115] Referring now to Figures 1, 3, and 5, the adjustable seat post 14 of the second bicycle B2 will be discussed in more detail. Here, the adjustable seat post 14 is a height-adjustable seat post. The adjustable seat post 14 essentially includes a first (inner or upper) tubular member 80, a second (outer or lower) tubular member 82, and a seat mount 82. The first tubular member 80 and the second tubular member 82 are telescopically configured to move between a retracted position and an extended position. The adjustable seat post 14 also includes an electric drive mechanism 84 provided on the seat mount 82 and operatively connected between the first tubular member 80 and the second tubular member 82 to adjust the relative position between the first tubular member 80 and the second tubular member 82. The specific configuration of the electric drive mechanism 84 can be any drive mechanism that can be used to telescopically move the first tubular member 80 relative to the second tubular member 82.

[0116] Here, in the adjustable seat post 14, the electrical component 30 is an electric motor or an electric actuator 84a of the electric drive mechanism 84. Furthermore, in the adjustable seat post 14, the power receiver 40 and the AC / DC converter 42 are housed by the electric drive mechanism 84. The adjustable seat post 14 also includes a battery unit 86 containing a charging power supply 32. Here, the battery unit 86 is detachably mounted to the housing of the electric drive mechanism 84. If the controller 38 of the adjustable seat post 14 determines that the parameters (e.g., temperature) of the charging power supply 32 of the adjustable seat post 14 are outside the allowable range, the controller 38 of the adjustable seat post 14 can restrict the operation of the electric motor or actuator 84a (electrical component 30) of the electric drive mechanism 84, so that the adjustable seat post 14 can only be lowered or set to a predetermined position.

[0117] Referring now to Figures 1, 3, and 6, the adjustable suspension 16 of the second bicycle B2 will be discussed in more detail. The adjustable suspension 16 is a front suspension fork, which basically includes a pair of first (inner or upper) tubular members 90, a pair of second (outer or lower) tubular members 92, a crown 94, and a steering tube 96. The first tubular members 90 and the second tubular members 92 are telescopically configured to absorb shocks in a conventional manner. The first tubular members 90 and the second tubular members 92 are used for conventional air shocks with hydraulic damping mechanisms. Here, the upper ends of the first tubular members 90 are connected together by the crown 94. The upper ends of the second tubular members 92 are connected together by a bracket 98. The steering tube 96 is fixed to the crown 94 so that the adjustable suspension 16 can be pivoted relative to the frame F by the handlebars H.

[0118] The adjustable suspension 16 also includes an electrically adjustable mechanism 100 provided to one of the first tubular members 90 to adjust or change the stiffness / flexibility and / or travel length of the adjustable suspension 16. Here, in the adjustable suspension 16, the electrical component 30 is an electric motor or electric actuator 100a of the electrically adjustable mechanism 100. Furthermore, in the adjustable suspension 16, a power receiver 40 and an AC / DC converter 42 are housed by the electrically adjustable mechanism 100. The adjustable suspension 16 also includes a battery unit 102 containing a charging power supply 32. Here, the battery unit 102 is detachably mounted to the housing of the electrically adjustable mechanism 100. If the controller 38 of the adjustable suspension 16 determines that the parameters (e.g., temperature) of the charging power supply 32 of the adjustable suspension 16 are outside the allowable range, the controller 38 of the adjustable suspension 16 may limit the operation function of the electric motor or actuator 100a (electrical component 30) of the electric adjustment mechanism 100, so that the adjustable suspension 16 can only change one function (rigidity / flexibility or travel length).

[0119] Referring now to Figures 1, 3, and 7, the lamp 20 provided to each of the first bicycle B1 and the second bicycle B2 will be discussed in more detail. The lamp 20 basically includes a lamp housing 104 and an electrical unit 106. The lamp housing 104 has a mounting clamp 104a, and the electrical unit 106 is electrically connected to a light-emitting element 104b. Here, in the lamp 20, the electrical component 30 is the light-emitting element 104b disposed in the lamp housing 104. Furthermore, in the lamp 20, a power receiver 40 and an AC / DC converter 42 are housed by the electrical unit 106. The lamp 20 also includes a battery unit 108 containing a charging power supply 32. Here, the battery unit 102 is detachably mounted to the housing of the electrical unit 106. If the controller 38 of the lamp 20 determines that the parameters (e.g., temperature) of the charging power supply 32 exceed the allowable range, the controller 38 of the lamp 20 can restrict the operating function of the light-emitting element 104b (electrical component 30), causing the lamp 20 to turn off or dim the output of the light-emitting element.

[0120] Referring now to Figures 1, 3, and 8, the adjustable front derailleur 18 of the first bicycle B1 will be discussed in more detail. The adjustable front derailleur 18 basically includes a base member 110, a chain guide 112, and a link 114. The base member 110 includes a frame mount 110a for mounting the adjustable front derailleur 18 to the frame F. The adjustable front derailleur 18 also includes an electric motor unit 116 provided on the base member 110, which is operatively coupled to the link 114 to move the chain guide 112 between at least two sprocket positions.

[0121] Here, in the front derailleur 18, the electrical component 30 is an electric motor or an electric actuator 116b of the electric motor unit 116. Furthermore, in the adjustable front derailleur 18, a power receiver 40 and an AC / DC converter 42 are housed by the electric motor unit 116. The adjustable front derailleur 18 further includes a battery unit 118 containing a charging power supply 32. Here, the battery unit 118 is detachably mounted to the housing of the electric motor unit 116. If the controller 38 of the adjustable front derailleur 18 determines that the parameters (e.g., temperature) of the charging power supply 32 of the adjustable front derailleur 18 are outside the allowable range, the controller 38 of the adjustable front derailleur 18 can restrict the operating function of the electric motor or actuator 116b (electrical component 30) of the electric motor unit 116, so that the adjustable front derailleur 18 can only downshift, only upshift, or move to a predetermined gear setting.

[0122] Referring now to Figures 1, 3, and 9, the rear derailleur 26 provided in each of the first bicycle B1 and the second bicycle B2 will be discussed in more detail. The rear derailleur 26 basically includes a base member 120, a chain guide 122, and a link 124. The base member 120 includes a frame mount 120a for mounting the rear derailleur 26 to the frame F. The rear derailleur 26 also includes an electric motor unit 126 provided on the base member 120, which is operatively coupled to the link 124 for moving the chain guide 122 between at least a plurality of sprocket positions.

[0123] Here, in the rear derailleur 26, the electrical component 30 is an electric motor or an electric actuator 126a of the electric motor unit 126. Furthermore, in the rear derailleur 26, the power receiver 40 and the AC / DC converter 42 are housed by the electric motor unit 116. The rear derailleur 26 also includes a battery unit 128 containing a charging power supply 32. Here, the battery unit 128 is detachably mounted to the housing of the electric motor unit 126. If the controller 38 of the rear derailleur 26 determines that the parameters (e.g., temperature) of the charging power supply 32 of the rear derailleur 26 are outside the allowable range, the controller 38 of the rear derailleur 26 can restrict the operation of the electric motor or actuator 126a (electrical component 30) of the electric motor unit 126 (electrical component 30), so that the rear derailleur 26 can only downshift, only upshift, or move to a predetermined gear setting.

[0124] Referring now to Figures 1 to 3 and Figure 10, the object retainer 21 provided to each of the first bicycle B1 and the second bicycle B2 will be discussed in more detail. Here, the object retainer 21 is constructed to hold a bicycle water bottle WB. However, the object retainer 21 is not limited to a bicycle water bottle. Instead, the object retainer 21 can be other types of retainers, such as a pump retainer. The bicycle assembly BC (e.g., the object retainer 21) basically includes a base member 130 and a power receiver 131. The power receiver 131 has the same construction as the power receiver 40 seen in Figure 3, except that the power receiver 131 has been adapted to be part of the object retainer 21.

[0125] The base member 130 is configured to be mounted to a bicycle (e.g., a first bicycle B1 or a second bicycle B2). Specifically, the base member 130 includes at least one mounting portion 132 that is mounted to a braze-on mount of the first bicycle B1 or the second bicycle B2 using at least one fastener. Here, the base member 130 includes a pair of mounting portions 132 that are mounted to a pair of braze-on mounts of the first bicycle B1 or the second bicycle B2 using a pair of fasteners. The base member 130 includes a retaining portion 134 configured to removably retain at least one object. Here, the retaining portion 134 is configured to retain a water bottle WB, such as a reusable or disposable water bottle. Depending on the configuration of the retaining portion 134, it may also be referred to as a retaining portion, a cage, a container, or a clip. Thus, in the illustrated embodiment, the object holder 21 includes a water bottle cage.

[0126] As shown in FIG. 10, the power receiver 131 is mounted on the base member 132. Specifically, the base member 132 includes a support portion 136 configured to support the power receiver 131. Basically, as shown in FIG. 3, the power receiver 141 includes a contactless charging portion 141a configured to wirelessly receive external power and provide external power to at least one of the charging power supply and electrical components. In addition, the power receiver 141 includes a wireless communicator 142 and a controller 144, similar to the other bicycle components BC discussed above. The power receiver 141 has a circuit board PCB on which the wireless communicator 142 and the controller 144 are provided. In this embodiment, the object holder 21 includes electrical components 146 and a charging power supply 148. Preferably, the circuit board PCB is provided with an AC-DC converter, such as the AC-DC converter 42 shown in FIG. 3 and discussed above. Preferably, the circuit board PCB is provided with a sensor, such as the sensor converter 44 shown in FIG. 3 and discussed above. Therefore, the circuitry of the circuit board PCB used to control the electrical component 146 (electrical component 30) and the charging power supply 148 is the same as the circuitry of Figure 3 discussed above regarding the other bicycle component BC. Here, in the object retainer 21, the electrical component 146 can be, for example, an indicator light, a decorative light, a water bottle heating element, etc. As shown in Figure 10, the electrical component 146 is a light-emitting element used to indicate the function of the object retainer 21, such as the charging level. The charging power supply 148 can be electrically connected to the other bicycle component BC via the wire EC1. In this way, external power can be supplied to the other bicycle component BC through the charging power supply 148.

[0127] If the controller 144 of the object holder 21 determines that the parameters (e.g., temperature) of the charging power supply 148 are outside the allowable range, the controller 148 of the object holder 21 may restrict the operating function of the electrical component 146. For example, if the electrical component 30 of the object holder 21 is a light-emitting element, the controller 144 may turn off or dim the output of the light-emitting element. Furthermore, for example, if the electrical component 146 of the object holder 21 is a water bottle heating element, the controller 144 may turn off or reduce the output of the water bottle heating element.

[0128] The power receiver 141 has a housing 150 that houses the contactless charging portion 131a and a circuit board PCB, the circuit board PCB including a wireless communicator 142, a controller 144, an AC-DC converter, and a sensor. Here, a charging power supply 148 is also disposed within the housing 150 of the power receiver 141. In this embodiment, the charging power supply 148 is disposed within the power receiver 141. However, the charging power supply 148 may be positioned away from the power receiver 141 as needed and / or desired. The housing 150 is preferably a waterproof structure. Therefore, the power receiver 141 includes a waterproof structure for housing the contactless charging portion. Here, the housing 150 is a two-piece structure, wherein the two parts are screwed together with a rubber seal disposed between the two parts. Thus, the housing 150 can be opened and closed to replace the charging power supply 148 or to repair components of the power receiver 141. Optionally, the housing 150 can be a one-piece component or two parts permanently coupled together.

[0129] Referring now to FIG. 11, when the first bicycle B1 or the second bicycle B2 is in motion, the charging power supply 32 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) is automatically charged by one of the contactless charging devices CD (22, 24). Therefore, according to the present disclosure, a contactless charging method for charging the charging power supply of the bicycle assembly is provided. Specifically, an exemplary contactless charging method or process for charging the charging power supply 32 of each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) is now described with reference to FIG. 11. The exemplary contactless charging method or process of FIG. 11 is executed by a controller 38 at predetermined time intervals and / or each time the electrical component 30 is operated. Once the predetermined time interval has elapsed and / or each time the electrical component 30 is operated, the controller 38 initiates the contactless charging process by communicating with the bicycle assembly BC and the contactless charging device CD. Therefore, the contactless charging method includes initiating wireless communication between the bicycle component BC and the contactless charging device CD. This wireless communication is in the form of voice indicating any information about the bicycle component BC, such as indicating the need for automatic charging of the bicycle component BC, or placing the bicycle component BC near the contactless charging device CD when the user decides to charge it. Once wireless communication exists between the bicycle component BC and the contactless charging device CD, the contactless charging method proceeds to step S1 in the flowchart of Figure 11.

[0130] In step S1, the controller 38 detects the state of the charging power supply 32. In other words, the contactless charging method includes detecting the state of the charging power supply 32. The state of the charging power supply 32 can be detected in a variety of ways. In any case, the detected state of the charging power supply 32 indicates the state of the charging power supply 32, which is related to at least one of the following: charging state, charging current, internal resistance, temperature, voltage, years of power supply use, electrical load, and any other parameter related to charging capability. In the illustrated embodiment, the temperature of the charging power supply 32 is used as the state of the charging power supply 32 being detected. Therefore, the contactless charging method also includes detecting the temperature of the charging power supply 32 as a state. After detecting the state of the charging power supply 32 (e.g., temperature and / or voltage), the controller 38 proceeds to step S2.

[0131] In step S2, the controller 38 confirms the parameters (e.g., temperature and / or voltage) of the charging power supply 32 based on the results of the detected state. In other words, the contactless charging method includes confirming the parameters of the charging power supply 32 based on the results of the detected state. Specifically, the controller 38 determines whether the detected state or parameters of the charging power supply 32 are within the allowable range. For example, the controller 38 may pre-store a charging table and / or charging map in memory, which controls charging based on one or more of a plurality of parameters such as charging state, charging current, internal resistance, temperature, voltage, years of power supply use, electrical load, and any other parameters related to charging capability.

[0132] Preferably, the parameter is an electrical load or electrical state, such as the remaining power of the charging power supply 32, or the temperature / heat of the charging power supply 32 or electrical device 30. The parameter (electrical load or electrical state) is detected using one or more sensors, and the information detected by the sensors is processed by the controller 38 to check whether the (electrical load or electrical state) is below or above an allowable range. For example, the electrical load of the charging power supply 32 can be determined based on the temperature detected by the temperature sensor 44A, and the electrical state (remaining power) of the charging power supply 32 can be determined based on the voltage detected by the voltage sensor 44B. If the temperature and / or remaining power is below an allowable range, the controller 38 will control the contactless charging section 34 to maintain the current charging level and / or phase. If the temperature and / or remaining power is above an allowable range, the controller 38 will control the contactless charging section 34 to adjust the charging level, such as by reducing the voltage and / or extending the charging time.

[0133] When the controller 38 determines that the charging state of the parameter indicating the charging power supply 32 is suitable for operating the bicycle component BC without any restrictions (i.e., allowing normal operation of the bicycle component BC), the controller proceeds to step S3.

[0134] In step S3, the controller 38 allows control of the bicycle component BC, enabling the bicycle component BC to operate without any restrictions (i.e., allowing normal operation of the bicycle component BC). In other words, the contactless charging method also includes maintaining the operation of the bicycle component BC when it is determined that the parameters of the charging power supply 32 are within the allowable range. Then, the controller 38 proceeds to step S4.

[0135] In step S4, the controller 38 starts or maintains a predetermined charging mode suitable for the detection state of the charging power supply 32. In other words, the contactless charging method includes charging the charging power supply 32 of the bicycle assembly BC. Here, the predetermined charging mode may be a preferred charging mode, such as a constant current charging mode. A preferred charging mode is used because the detection state of the charging power supply 32 indicates that the bicycle assembly BC can operate without restriction and the charging power supply 32 can be optimally charged. Furthermore, in the illustrated embodiment, as described above, the contactless charging section 34 output is provided. Therefore, in the illustrated embodiment, an AC-DC converter 42 is provided between the contactless charging section 34 and the charging power supply 32 to convert the AC power output by the contactless charging section 34 into DC power received by the charging power supply 32. Therefore, in the illustrated embodiment, the contactless charging method also includes converting the AC power from the contactless charging section 34 into DC power supplied to the charging power supply 32. Then, the controller 38 proceeds to step S5.

[0136] In step S5, the controller 38 uses a voltage sensor 44B to monitor the voltage of the charging power supply 32. The voltage sensor 44B directly detects the voltage of the charging power supply 32 or indirectly detects the voltage of the charging power supply 32 by detecting the voltage of the electrical component 30. Therefore, the contactless charging method also includes monitoring the voltage of the charging power supply 32 after a predetermined period of time has elapsed since the start of charging. Then, the controller 38 proceeds to step S6.

[0137] In step S6, the controller 38 determines whether the charging power supply 32 is fully charged (i.e., charged to a predetermined level to stop charging). As used herein, the term "fully charged" does not require charging the charging power supply 32 to its maximum capacity. Rather, the term "fully charged" may include a charging capacity less than the maximum capacity. If the controller 38 determines that the charging power supply 32 has reached the desired fully charged capacity, the contactless charging method ends until the next time interval or the bicycle component BC is operated. On the other hand, if the controller 38 determines that the charging power supply 32 has not yet reached the required fully charged capacity, the contactless charging method returns to step S1 to detect the state of the charging power supply 32 and proceeds to step S2.

[0138] In step S2, if the controller 38 determines that the parameter is outside the allowable range based on the detection state of the charging power supply 32, the controller 38 proceeds to step S7.

[0139] In step S7, the controller 38 restricts the control of the bicycle component BC, so that the bicycle component BC cannot be operated, or can only be operated with certain functions or reduced performance. In other words, the contactless charging method also includes restricting the operational functions of the bicycle component BC when it is determined that the parameters of the charging power supply 32 are outside the allowable range. Then, the controller 38 proceeds to step S8.

[0140] In step S8, the controller 38 is configured to implement measures to reduce the temperature of the charging power supply 32. In other words, the contactless charging method also includes applying thermal management to reduce the temperature of the charging power supply 32. For example, the charging power supply 32 can be cooled using heat pipes, fans, etc. Of course, it will be apparent from this disclosure that step S8 can be omitted or skipped as needed and / or desired. Then, the controller 38 proceeds to step S9.

[0141] In step S9, the controller 38 adjusts the voltage of the charging power supply 32 to change the charging mode from a preferred charging mode (e.g., constant current mode) to a charging mode more suitable for the detection state of the charging power supply 32 (e.g., low voltage mode). When charging the charging power supply 32 using the low voltage mode, the voltage supplied to the charging power supply 32 is reduced relative to the voltage supplied to the charging power supply 32 when it is determined that the parameters of the charging power supply 32 are outside the allowable range. In other words, the contactless charging method also includes adjusting the voltage of the charging power supply 32 when it is determined that the parameters of the charging power supply 32 are outside the allowable range. Then, the controller 38 proceeds to step S6, where the controller 38 determines whether the charging power supply 32 is fully charged, as described below.

[0142] Referring now to FIG12, when the controller 38 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26) determines that the first bicycle B1 or the second bicycle B2 is stopped, or when the bicycle assembly BC is not installed on the bicycle B, it is not necessary to restrict the operation function of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26). Therefore, when the first bicycle B1 and the second bicycle B2 are stopped, or when the bicycle assembly BC is not installed on the first bicycle B1 and the second bicycle B2, the contactless charging method of FIG12 is executed to charge the charging power supply 32 of each bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26).

[0143] Basically, the contactless charging method of FIG12 is the same as that of FIG11, except that steps S7 and S3 of the contactless charging method of FIG11 have been omitted from the contactless charging method of FIG12. Therefore, steps S1, S2 and S4 to S9 of the contactless charging method of FIG12 are the same as steps S1, S2 and S4 to S9 of the contactless charging method of FIG11. For the sake of brevity, the description of steps S1, S2 and S4 to S9 will not be repeated for the contactless charging method of FIG12.

[0144] Referring now to Figure 13, optionally, the controller 38 of each or some bicycle components BC (12, 12', 14, 16, 18, 20, 21, 26) can be configured to execute a process to begin charging the charging power supply 32 when it is determined that the charging power supply 32 has dropped below a predetermined charging level. The process of Figure 13 is executed by the controller 38 at predetermined time intervals and / or each time the electrical component 30 is operated.

[0145] Here, in step S10, the controller 38 uses a voltage sensor 44B to detect the voltage of the charging power supply 32. The voltage sensor 44B can detect the voltage of the charging power supply 32 directly or indirectly by detecting the voltage of the electrical component 30. Then, the controller 38 proceeds to step S11.

[0146] In step S11, the controller 38 determines whether the charging level of the charging power supply has fallen below a threshold. The threshold may be the same for each or some bicycle components BC (12, 12', 14, 16, 18, 20, 21, 26). Alternatively, the threshold may be different for each or some bicycle components BC (12, 12', 14, 16, 18, 20, 21, 26). If the controller 38 determines that the charging level of the charging power supply has fallen below the threshold, the controller 38 proceeds to step S12. On the other hand, if the controller 38 determines that the charging level of the charging power supply has fallen above the threshold, the process ends until the next time interval or when a bicycle component BC is operated.

[0147] In step S12, the controller 38 instructs the wireless communicator 36 to transmit information relating to the state of the charging power supply 32. This information relating to the state of the charging power supply 32 is received by the wireless communicator 52 of one or both of the contactless charging devices CD (22, 24). Thus, the controller 54 of the power transmitter 60 can control the wireless transmission of power from the power source 48 via the contactless charging coil 50a to the contactless charging coil 34a of the power receiver 40 of the bicycle assembly BC (12, 12', 14, 16, 18, 20, 21, 26).

[0148] Referring now to Figures 14 and 15, a contactless charging system 210 is shown. The contactless charging system 210 basically includes a bicycle assembly BC and a contactless charging device CD. In this embodiment, the wireless communicator has been omitted from the contactless charging system 210. However, if needed and / or desired, the wireless communicator of the contactless charging system 10 may be included in the contactless charging system 210.

[0149] The bicycle assembly BC (e.g., object retainer 212) essentially includes a base member 214 and a power receiver 216. The power receiver 216 is configured to receive power from a contactless charging device CD. Here, the power receiver 216 includes a wire EC1 configured to supply external power to at least one of the charging power source and electrical components. Thus, the power receiver 216 can charge at least one charging power source or supply power to at least one electrical component, such as one of the bicycle assemblies (12, 12', 14, 16, 18, 20, 26). The charging power source can be provided to the power receiver 216 or to one of the bicycle assemblies BC (12, 12', 14, 16, 18, 20, 26) of the first bicycle B1 or the second bicycle B2.

[0150] Basically, the contactless charging device CD can be electrically connected to a power source, such as a home or building's power grid, via a wire EC2. External power received from the home or building's power grid can then be wirelessly transmitted from the contactless charging device CD to the object holder 212. The contactless charging device CD is configured to be supported by the object holder 212 to supply external power to the power receiver 216 of the object holder 212. In this way, the contactless charging device CD is supported by the object holder 212 during power transmission.

[0151] In an embodiment, an object retainer 212 may be provided on each of the first bicycle B1 (see FIG. 1) and the second bicycle B2 (see FIG. 1). Here, the object retainer 212 is configured to hold a bicycle water bottle. However, the object retainer 212 is not limited to a bicycle water bottle. Instead, the object retainer 212 can be other types of retainers, such as a pump retainer.

[0152] The base member 214 is configured to be mounted to a bicycle (e.g., a first bicycle B1 or a second bicycle B2). Specifically, the base member 214 includes at least one mounting portion 218 that is mounted to a braze-on mount of the first bicycle B1 or the second bicycle B2 using at least one fastener. Here, the base member 214 includes a pair of mounting portions 218 that are mounted to a pair of braze-on mounts of the first bicycle B1 or the second bicycle B2 using a pair of fasteners. The base member 214 includes a retaining portion 220. The retaining portion 220 is configured to removably retain at least one object. Here, the retaining portion 220 is configured to retain a water bottle, such as a reusable or disposable water bottle. Specifically, the retaining portion 220 supports the side of the object or water bottle. Depending on the configuration of the retaining portion 220, it may also be referred to as a retaining portion, a cage, a container, or a clip. Therefore, in the illustrated embodiment, the object holder 212 includes a water bottle holder. Furthermore, the retaining portion 220 is configured to support the contactless charging device CD. In this way, the contactless charging device CD is supported by the object holder 212 during power transmission.

[0153] The power receiver 216 is mounted to the base member 214. Specifically, the base member 132 includes a support portion 222 configured to support the power receiver 216. Here, the support portion 222 is located at the bottom of the holding portion 220, allowing the bottom of the water bottle to rest on the support portion 222. When the contactless charging device CD is disposed in the holding portion 220, the support portion 222 also supports the contactless charging device CD. Alternatively, the support portion 222 may be integrated into the power receiver 216, allowing the contactless charging device CD to rest directly on the power receiver 216.

[0154] However, the location of the power receiver 216 is not limited to the support portion 222. Instead, for example, the power receiver 216' may be located on the side of the retaining portion 220, as shown by the dashed line in FIG14. Furthermore, for example, the power receiver 216" may be integrated into the mounting portion 218, as shown by the dashed line in FIG14.

[0155] Basically, as seen in FIG16, the power receiver 216 includes a contactless charging section 224 configured to wirelessly receive external power and supply external power to at least one of the charging power source and electrical components. The contactless charging section 224 includes at least a contactless charging coil 224a. At least the contactless charging coil 224a may include near field communication (NFC). Furthermore, as shown in FIG16, the power receiver 216 includes a controller 226. The controller 226 is also configured to control the charging process. The controller 226 is preferably an electronic controller including a central processing unit (CPU) or a microprocessor unit (MPU). Preferably, the controller 226 includes one or more processors and one or more storage devices. The storage devices store the programs used by the controller 226. The storage devices are any computer storage devices or any computer-readable media, with the only exception being transient propagation signals. For example, storage devices can be non-volatile memory and volatile memory, and may include ROM (read-only memory) devices, RAM (random access memory) devices, hard disks, flash drives, etc.

[0156] In this embodiment, the object retainer 212 is electrically connected to at least one other bicycle assembly BC (e.g., bicycle assemblies 12, 12', 14, 16, 18, 20, 26) via wire EC1. Here, a charging power supply 228, separate from the object retainer 212 and the bicycle assembly BC, is provided. The charging power supply 228 is configured to receive power from the contactless charging portion 224 of the object retainer 212.

[0157] In this embodiment, the object holder 212 further includes an AC-DC converter 232. The AC-DC converter 232 converts the AC power output from the contactless charging section 224 into DC power received by the charging power supply 228. Thus, the DC power output by the AC-DC converter 232 can be used to charge the charging power supply 228.

[0158] The bicycle assembly BC that receives power from the charging power source 228 preferably has a controller, electrical components, and sensors electrically connected to the charging power source 228. The sensors are configured to detect information related to the state of the charging power source 228. The sensors are configured to communicate with the controller 230 of the power receiver 216. Sensor 234 may be configured to communicate with the controller of the bicycle assembly BC, which in turn communicates with the controller 226 of the power receiver 216. By using the sensors, the charging of the charging power source 228 can be improved based on the state of the charging power source 228.

[0159] The bicycle assembly BC that receives power from the charging power source 228 also includes electrical components that receive power from the charging power source 228. Depending on the bicycle assembly BC, the electrical components can be various electrical components, such as an electric motor, an electrical switch, a light-emitting diode, or an electric actuator. For example, if the bicycle assembly BC is a derailleur, the electrical component can be an electric motor. If the bicycle assembly BC is an operating device, the electrical component can be an electrical switch. Preferably, the sensors of the bicycle assembly BC that receive power from the charging power source 228 include a temperature sensor and a voltage sensor, the temperature sensor being configured to detect the temperature of the charging power source 228, and the voltage sensor being configured to detect at least one of the voltage of the charging power source 228 and the voltage supplied to the charging power source 228. The temperature sensor 234A and the voltage sensor 234B operate in the same manner as the temperature sensor 44A and the voltage sensor 44B discussed above.

[0160] As shown in Figures 14 and 15, the power receiver 216 has a housing 236 coupled to the base member 214. As shown in Figure 16, the housing 236 is configured to house the contactless charging section 224, the controller 226, and the AC / DC converter 232. The housing 236 is preferably a waterproof structure. Therefore, the power receiver 216 includes a waterproof structure for housing the contactless charging section 224.

[0161] Alternatively, as shown by a dash-dot dash, the AC-DC converter 232 may be provided on the bicycle assembly BC', rather than subsequently in the housing 236 of the power receiver 216. Thus, the power receiver 216 has a housing 236' (shown by a dash-dot dash) that houses the contactless charging section 224 and the controller 226. Alternatively, as shown by a two-dot dash, the power receiver 216 has a housing 236'”, which is configured to house the contactless charging section 224, the controller 226, the charging power supply 228, and the AC-DC converter 232.

[0162] Here, as shown in Figures 14 and 16, the contactless charging device CD includes a housing 240 and a transmitter 242. The housing 240 is configured to be supported by a base member 214. The transmitter 242 is configured to wirelessly transmit power to the contactless charging portion 224. The transmitter 242 is a power transmitter including the contactless charging portion 244, which is configured to wirelessly transmit power to the contactless charging portion 224 of the power receiver 216. The contactless charging portion 244 includes a contactless charging coil 244a. The contactless charging coil 244a can use near field communication (NFC) to transmit power to the contactless charging portion 224 of the power receiver 216. Alternatively, the contactless charging coil 244a can use magnetic resonance to transmit power to the contactless charging portion 224 of the power receiver 216.

[0163] The transmitter 242 includes a controller 246 to control the power receiver 216 to transmit power from the contactless charging coil 244a. The controller 246 is preferably an electronic controller including a central processing unit (CPU) or a microprocessor unit (MPU). Preferably, the controller 246 includes one or more processors and one or more storage devices. The storage device stores the program used by the controller 246. The storage device can be any computer storage device or any computer-readable medium, with the only exception being transient propagation signals. For example, the storage device can be non-volatile memory and volatile memory, and may include ROM (read-only memory) devices, RAM (random access memory) devices, hard disks, flash drives, etc.
