[0025] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Note that the present invention is not limited to this embodiment. Furthermore, when there are multiple embodiments, the present invention also includes an embodiment configured by combining the respective embodiments. For example, in this embodiment, the human-powered vehicle 100 is described as a bicycle, but it can also be used for vehicles driven by other power sources.

[0026] (Embodiment 1) The human-powered vehicle 100 in which the brake system 1 of this embodiment is used is, for example, a bicycle. The human-powered vehicle 100 is not limited to a bicycle. The human-powered vehicle 100 includes an electric bicycle or other two-wheeled electric vehicles. The human-powered vehicle 100 includes vehicles that do not require a license to drive on public roads. The human-powered vehicle 100 does not include vehicles that have an internal combustion engine.

[0027] As shown in FIG. 1, the human-powered vehicle 100 includes a handlebar 10, a frame 16, a battery 18, wheels W, and a drive train DT. The wheels W include a front wheel (front wheel WF) and a rear wheel (rear wheel WR). The front wheel WF includes a hub assembly HAF. The rear wheel WR includes a hub assembly HAR. A disc brake rotor RT is provided on each of the hub assembly HAF of the front wheel WF and the hub assembly HAR of the rear wheel WR. In this embodiment, the terms "front", "rear", "left", "right", "upper", and "lower", as well as terms synonymous therewith, refer to the "front", "rear", "left", "right", "upper", and "lower" as viewed from a state in which a user is sitting on a saddle S facing the handlebar 10.

[0028] The drive train DT includes a crank assembly FCW, a front sprocket FS, a rear sprocket RS, and a chain CN. The crank assembly FCW includes a pair of crank arms FCA and a pair of pedals PD. The pair of pedals PD are rotatably attached to the respective ends of the pair of crank arms FCA.

[0029] The front sprocket FS is provided to the crank assembly FCW. The rear sprocket RS is provided to the hub assembly HAR of the rear wheel WR. The chain CN is wound around the front sprocket FS and the rear sprocket RS. A driving force applied to the pedals PD by a rider of the human-powered vehicle 100 is transmitted to the rear wheel WR via the front sprocket FS, the chain CN, and the rear sprocket RS.

[0030] The human-powered vehicle 100 further includes an electric driving assist device 20. The electric driving assist device 20 operates to assist the propulsive force of the human-powered vehicle 100. The electric driving assist device 20 operates, for example, in response to a driving force applied to the pedals PD. The electric driving assist device 20 includes an electric motor 22. The electric driving assist device 20 is driven by electric power supplied from a battery 18 mounted on the human-powered vehicle 100. In this embodiment, the battery 18 is provided on the outer surface of the frame 16. The battery 18 supplies electric power to a control device 110, an operation device 2, and a brake device 3, which will be described later. It is to be noted that the electric driving assist device 20 may be omitted from the human-powered vehicle 100.

[0031] 2, the brake system 1 includes an operating device 2 and a brake device 3. The operating device 2 is configured to operate a component (the brake device 3 in this embodiment) in the human-powered vehicle 100. The operating device 2 includes an operating section 32, a transmission mechanism 34, and a power generation section 36. Note that the component operated by the operating device 2 is not limited to the brake device 3. The operating device 2 can operate any component, such as the electric driving assist device 20, a gear shifting device, an adjustable seat post, a suspension, a cycle computer, or other devices mounted on the human-powered vehicle 100.

[0032] As shown in FIG. 3, the operating unit 32 is a brake lever for operating the braking device 3. The operating device 2 further includes a base 28 on which the operating unit 32 and the power generation unit 36 ​​are provided. The base 28 is attached to the handlebar 10 by a clamp 12. The operating unit 32 is connected to the base 28 via the shaft 14. The operating unit 32 is provided so as to be able to swing around the shaft 14 as a central axis. Note that the operating unit 32 is not limited to a brake lever as long as it operates the braking device 3. For example, the operating unit 32 may be a switch device or the like.

[0033] The operating unit 32 is configured to be displaceable from a standby position P1 to an operating position P2, and further includes a biasing member 46 that biases the operating unit 32 toward the standby position P1. The operating position P2 is closer to the handlebar 10 than the standby position P1. When the user grips the handlebar 10 and holds the operating unit 32, the operating unit 32 is displaced from the standby position P1 to the operating position P2. When the user releases the operating unit 32, the biasing force of the biasing member 46 causes the operating unit 32 to return from the operating position P2 to the standby position P1. The biasing member 46 is a coil spring, a leaf spring, or the like.

[0034] The power generation unit 36 ​​includes a piezoelectric element 62. The operation device 2 further includes a transmission mechanism 34 that applies pressure to the piezoelectric element 62 in response to an input to the operation unit 32. The piezoelectric element 62 is attached inside a housing 64 fixed to the base 28. The transmission mechanism 34 is connected to the operation unit 32 and extends inside the housing 64. A pressing surface 34a of the transmission mechanism 34 is disposed between the handlebar 10 and the piezoelectric element 62. The transmission mechanism 34 is a link. The transmission mechanism 34 may also be a link mechanism in which a plurality of links are combined.

[0035] When the operating unit 32 is displaced from the standby position P1 to the operating position P2, the transmission mechanism 34 is displaced in a direction away from the handlebar 10. As a result, the pressing surface 34a of the transmission mechanism 34 comes into contact with the piezoelectric element 62, and the transmission mechanism 34 applies pressure to the piezoelectric element 62. In this manner, the operating unit 32 is provided so as to be displaceable, and the transmission mechanism 34 is configured to apply pressure to the piezoelectric element 62 in response to the displacement of the operating unit 32. As a result, the piezoelectric element 62 generates a voltage in response to the applied pressure.

[0036] Thus, the operating device 2 is a device for operating the brake device 3 of the human-powered vehicle 100, and includes an operating unit 32 that is operated by the user, and a power generation unit 36 ​​that converts input to the operating unit 32 into electricity.

[0037] The configuration of the transmission mechanism 34 is not limited to that shown in FIG. 3. The transmission mechanism 34 may be a link mechanism. In this case, the transmission mechanism 34 may be displaced in a direction approaching the handlebar 10 when the operation unit 32 is displaced from the standby position P1 to the operation position P2. The mounting position of the piezoelectric element 62 can also be changed appropriately in accordance with the transmission mechanism 34. The piezoelectric element 62 may be disposed between the pressing surface 34a of the transmission mechanism 34 and the handlebar 10. Also, the transmission mechanism 34 may be omitted in the operation device 2. In this case, in the operation device 2, for example, the operation unit 32 is fixedly provided to the base 28, and the piezoelectric element 62 is provided in the operation unit 32 or between the operation unit 32 and the base 28.

[0038] As shown in Fig. 2, the operation device 2 further includes a power storage unit 38 that stores power from the power generation unit 36. The power storage unit 38 is a rechargeable battery (secondary battery). The power storage unit 38 is a lithium ion battery, but any type of battery may be used as long as it is a rechargeable battery. The power stored in the power storage unit 38 can be used to drive the brake device 3, the sensor 40, the wireless communication unit 42, and the control device 110. In addition, the power of the power generation unit 36 ​​may be used as a power source for driving a user interface (UI).

[0039] The operating device 2 further includes a sensor 40 configured to detect the amount of displacement of the operating unit 32. The sensor 40 is driven by power from the power generation unit 36. The sensor 40 is configured to detect the amount of displacement of the operating unit 32 based on the amount of power generated by the power generation unit 36. The sensor 40 is a voltage sensor or a current sensor. Note that the sensor 40 is not limited to being supplied with power from the power generation unit 36, and may be driven by power from the power storage unit 38. The sensor 40 may also be an angle sensor or angular acceleration sensor that detects the swing angle of the operating unit 32 around the shaft 14 as the central axis, or a displacement sensor that detects the amount of displacement of the operating unit 32.

[0040] The operation device 2 further includes a wireless communication unit 42 driven by power from the power generation unit 36. The wireless communication unit 42 can wirelessly transmit various information to the control device 110. The various information includes information on the amount of displacement of the operation unit 32 detected by the sensor 40, information on the power generated by the power generation unit 36, and information on the power stored in the power storage unit 38. The control device 110 controls the operation of the operation device 2 and the brake device 3. The control device 110 includes, for example, a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and a flash memory. Note that the operation device 2 may not include the wireless communication unit 42 and may include a wired communication unit capable of transmitting various information by wire. The control device 110 may be provided as an operation unit in one of the operation device 2 and the component to be operated (the brake device 3 in this embodiment).

[0041] The operating device 2 further includes a notification unit 44 that notifies the user of various information. The notification unit 44 is a speaker that generates warning sounds, a vibration generator that generates vibrations, and a display device that displays various information. The display device displays information such as the amount of stored power in the power storage unit 38 and the amount of power generated by the power generation unit 36. Based on information from the wireless communication unit 42, when the amount of stored power decreases or when an abnormality occurs in the operation of the power generation unit 36, the control device 110 notifies the user of various information through the notification unit 44.

[0042] The power generation unit 36 ​​also functions as the notification unit 44. The piezoelectric element 62 is driven to vibrate by power from at least one of the power storage unit 38, the battery 18, and a power supply device (not shown). This enables the power generation unit 36 ​​to notify the user of various information.

[0043] The power storage unit 38, the sensor 40, the wireless communication unit 42, the notification unit 44, and the urging member 46 are provided in the base unit 28 or the operation unit 32 shown in Fig. 3. The operation device 2 may be configured without one or more of the power storage unit 38, the sensor 40, the wireless communication unit 42, the notification unit 44, and the urging member 46.

[0044] As shown in FIG. 2, the control device 110 supplies a drive signal to the brake device 3 based on information on the displacement amount of the operation unit 32 to operate the brake device 3. In this embodiment, the brake device 3 is a disc brake caliper. The brake device 3 has a brake pad 56 and an electric drive unit 58 driven by electricity. As shown in FIG. 1, the brake device 3 is provided so as to correspond to the disc brake rotor RT of the front wheel WF and the disc brake rotor RT of the rear wheel WR, respectively. That is, two brake devices 3 are provided in the human-powered vehicle 100. Correspondingly, two operation devices 2 are provided on the left and right sides of the handlebar 10. Note that only the operation device 2 on the right side is shown in FIG. 1. The brake system 1 of this embodiment is configured to operate one brake device 3 by one operation device 2. Note that the control device 110 may be shared by two operation devices 2 and two brake devices 3. Note that the brake system 1 may be configured to operate two brake devices 3 by one operation device 2.

[0045] The brake device 3 is partially provided on the periphery of a disc brake rotor RT, which is a rotating body. The brake device 3 has two brake pads 56 arranged to face each other with the disc brake rotor RT in between.

[0046] The electric drive unit 58 is supplied with power from the power storage unit 38 or the power generation unit 36. The electric drive unit 58 is supplied with power from the power storage unit 38 during normal operation, and is supplied with power from at least one of the power generation unit 36 ​​and the battery 18 when the amount of stored power in the power storage unit 38 decreases. The electric drive unit 58 is an actuator having a screw, a cam, or the like, and is configured to move at least one of the two brake pads 56. The electric drive unit 58 presses the brake pad 56 against the disc brake rotor RT by electric power. The wheel W is braked by friction generated between the brake pad 56 and the disc brake rotor RT. The electric drive unit 58 may also have a hydraulic device including a cylinder and a piston. In this case, the electric drive unit 58 can operate the piston by electric power and move the brake pad 56 by hydraulic pressure in the cylinder.

[0047] The brake device 3 is not limited to a disc brake caliper, but may be a rim brake in which a brake shoe contacts the rim of the wheel W, or a drum brake in which a brake shoe contacts a drum provided on a hub, etc.

[0048] (Embodiment 2) 4 shows a portion of the operating device 2A where the power generation unit 36A and the transmission mechanism 34A are connected. Note that the same components as those in the above-described embodiment are given the same reference numerals and the description thereof will be omitted.

[0049] As shown in Fig. 4, the operating device 2A further includes a transmission mechanism 34A configured to transmit the displacement of the operating unit 32 (see Fig. 3) to the power generation unit 36A. The transmission mechanism 34A has a pulley 72 connected to the power generation unit 36A, and a connection member 74 that connects the operating unit 32 and the pulley 72 so as to rotate the pulley 72 in response to the displacement of the operating unit 32. The connection member 74 is a string-like (linear) member such as a wire, and is wound around a groove provided on the outer periphery of the pulley 72. The connection member 74 is connected to the pulley 72 with an offset relative to the central axis of the pulley 72 so as to rotate the pulley 72 in response to the displacement of the operating unit 32 from the standby position P1 to the operating position P2.

[0050] The power generating unit 36A is a dynamo having a rotor 66 and a stator 68. The rotor 66 is connected to a pulley 72 via a shaft 70 and rotates together with the pulley 72. The rotor 66 has a magnet. The stator 68 has a cage-shaped (cylindrical) yoke 68a and a coil 68b provided at one end thereof. In this embodiment, the rotor 66 is disposed inside the stator 68. However, without being limited thereto, the power generating unit 36A may be configured such that the rotor 66 is formed in a cylindrical shape and rotates outside the stator 68. Note that the operating device 2A may have a speed-up mechanism between the pulley 72 and the rotor 66 that speeds up the rotation of the pulley 72 and transmits it to the power generating unit 36A. In this way, when the power generating unit 36A is a dynamo, the power generating unit 36A functions as the notification unit 44 by driving the power generating unit 36 ​​as an electric motor. By displacing or vibrating the operation unit 32 due to the rotation of the rotor 66 of the power generation unit 36A, various information can be notified to the user.

[0051] (Embodiment 3) As shown in FIG. 5, in an operating device 2B of the third embodiment, a power generation unit 36A is provided so as to overlap with the shaft 14 of the base .

[0052] As shown in FIG. 6, the transmission mechanism 34B has a first gear 76 and a second gear 78. The first gear 76 is connected to the shaft 14, and the oscillation of the operating unit 32 is transmitted to the first gear 76. This allows the first gear 76 to rotate around the shaft 14 as a central axis. The teeth of the first gear 76 mesh with the teeth of the second gear 78. The second gear 78 is connected to the rotor 66 of the power generation unit 36A via the shaft 70. In this way, the transmission mechanism 34B has a plurality of gears (the first gear 76 and the second gear 78) provided between the operating unit 32 and the power generation unit 36 ​​so as to transmit the displacement of the operating unit 32 to the power generation unit 36.

[0053] The number of teeth of the first gear 76 is greater than the number of teeth of the second gear 78. Therefore, the rotation speed of the second gear 78 is greater than the rotation speed of the first gear 76. In this manner, the multiple gears are configured to accelerate the displacement of the operation unit 32 and transmit it to the power generation unit 36A.

[0054] The transmission mechanism 34B also has a one-way structure 80 configured to transmit only the displacement of the operating unit 32 in a predetermined direction to the power generation unit 36A via a plurality of gears (first gear 76 and second gear 78). The one-way structure 80 is provided between the shaft 14 and the first gear 76. The one-way structure 80 is a clutch (one-way clutch) that transmits only the rotation of the shaft 14 in one direction to the first gear 76. The one-way structure 80 is configured to transmit the rotation of the shaft 14 to the power generation unit 36A when the operating unit 32 is displaced from the standby position P1 to the operating position P2. On the other hand, the one-way structure 80 is configured not to transmit the rotation of the shaft 14 to the power generation unit 36A when the operating unit 32 is displaced from the operating position P2 to the standby position P1.

[0055] (Embodiment 4) Fig. 7 shows a cross-sectional view of a transmission mechanism 34C of an operating device 2C, with the power generation unit 36 ​​indicated by a two-dot chain line. As shown in Fig. 7, in the operating device 2C of this embodiment, the transmission mechanism 34C has a piston 84 that is connected to the operating unit 32 and moves in response to the displacement of the operating unit 32, a cylinder 82 that houses the piston 84, and a drive unit 86 that drives the power generation unit 36A by fluid pressure generated in response to the movement of the piston 84.

[0056] The piston 84 is connected to the operating unit 32 via the rod 84a. When the operating unit 32 is displaced from the standby position P1 to the operating position P2, a force is applied to the piston 84 from the rod 84a. This causes the piston 84 to slide in the axial direction of the cylinder 82. The piston 84 slides so that the volume of the cylinder chamber 82a of the cylinder 82 becomes smaller. The cylinder chamber 82a is filled with hydraulic fluid 88. The movement of the piston 84 changes the hydraulic pressure of the hydraulic fluid 88.

[0057] One end of a pipe 82b is connected to an end of the cylinder 82. The inside of the pipe 82b is fluidly connected to the cylinder chamber 82a. A reservoir tank (not shown) capable of storing hydraulic fluid 88 is connected to the cylinder 82. In the pipe 82b, hydraulic fluid 88 flows due to a change in hydraulic pressure of the hydraulic fluid 88 generated in the cylinder 82, generating fluid pressure.

[0058] The drive unit 86 is provided in the tube 82b and is rotatable around a shaft 86a. The drive unit 86 is coupled to the rotor 66 (see FIG. 6) of the power generation unit 36A via the shaft 86a. The drive unit 86 is, for example, an impeller, and is rotated by the fluid pressure of the working fluid 88 passing through the tube 82b. This drives the rotor 66 of the power generation unit 36A.
