[0019] The electric bicycle 1 is a bicycle that can travel on a riding surface 100 by electric power. In the first embodiment, the electric bicycle 1 is an electrically assisted bicycle in which a motor 141 assists the pedaling force (pedaling force) of the user.

[0020] The electric bicycle 1 according to the first embodiment includes a bicycle body 10 (vehicle body). A handlebar 22 and a saddle 17 are attached to the bicycle body 10.

[0021] The electric bicycle 1 includes wheels 16 and a bicycle body 10 supported by the wheels 16, and is equipped with a display device 3. The display device 3 includes direction indicator lights 4 and riding mode indicator lights 5.

[0022] (2) Composition Next, the configurations of the electric bicycle 1 and the drive unit 14 according to the first embodiment will be described with reference to the drawings.

[0023] The electric bicycle 1 according to the first embodiment is configured to be capable of traveling in a plurality of travel modes. The electric bicycle 1 includes a frame 11, a battery unit 13, and a drive unit 14. The electric bicycle 1 also includes a cover 15, a plurality of wheels 16 (two wheels, a front wheel 161 and a rear wheel 162, in the illustrated example), a saddle 17, a pair of crank arms 18 (one in the illustrated example), and a pair of pedals 19 (one in the illustrated example). The electric bicycle 1 also includes a front fork 21, a handlebar 22, a power transmission body 23, a front basket 24, a front fender 25, a rear fender 26, an operating device 27, and a rear carrier 29. In the first embodiment, the frame 11, the drive unit 14, the cover 15, the front basket 24, the handlebar 22, and the saddle 17 form a bicycle main body 10.

[0024] (2.1) Frame The frame 11 is a framework to which the multiple wheels 16, the front fork 21, the handlebars 22, the saddle 17, the battery unit 13, and the drive unit 14 are attached. The material of the frame 11 is, for example, an aluminum alloy containing aluminum as a main component. However, the material of the frame 11 is not limited to an aluminum alloy, and may be, for example, iron, chrome molybdenum steel, high tensile steel, titanium, or magnesium. Furthermore, the material of the frame 11 is not limited to a metal, and may be, for example, carbon, wood, bamboo, or fiber reinforced synthetic resin (e.g., CFRP; Carbon Fiber Reinforced Plastics).

[0025] The frame 11 of the first embodiment includes a head tube 111, a down tube 112, a seat tube 113, a pair of seat stays 114 (one in the illustrated example), and a pair of chain stays 115 (one in the illustrated example). In other words, the bicycle body 10 includes a frame 11 having a plurality of pipes. The frame 11 also includes a bracket 116. In this disclosure, a "pipe" refers to a long, thin, hollow member. The cross-sectional shape of the pipe in this disclosure may be, for example, a circle (including a perfect circle, an oval, and an ellipse), a rectangle (including a square), a hexagon, or an octagon.

[0026] (2.1.1) Head tube The head tube 111 is a pipe that supports the front fork 21. The central axis of the head tube 111 is inclined with respect to the riding surface 100 so that it approaches the rear as it approaches the upper direction. The steering column 213 passes through the head tube 111 so that the central axis of the head tube 111 and the central axis of the steering column 213 are aligned. This allows the head tube 111 to rotatably support the steering column 213. In the first embodiment, the rotation axis of the steering column 213 is the same as the central axis of the head tube 111.

[0027] (2.1.2) Downtube The down tube 112 is a pipe that connects the head tube 111 and the seat tube 113. The front end of the down tube 112 in the longitudinal direction is connected to the head tube 111. The rear end of the down tube 112 in the longitudinal direction is connected to a bracket 116. In the first embodiment, the longitudinal direction of the down tube 112 is inclined with respect to the riding surface 100 so as to extend downward in the rearward direction.

[0028] (2.1.3) Seat tube The seat tube 113 is a pipe that holds the saddle 17. The lower end of the seat tube 113 in the longitudinal direction is connected to a bracket 116. The saddle 17 is movably attached to the upper end of the seat tube 113 in the longitudinal direction. The central axis of the seat tube 113 is inclined with respect to the riding surface 100 so as to move rearward as it moves upward from the lower end. The rear end of the down tube 112 in the longitudinal direction is connected to the lower end of the seat tube 113 via the bracket 116. In the first embodiment, the battery unit 13 is removably attached to the seat tube 113.

[0029] (2.1.4) Chainstay The pair of chain stays 115 are pipes that support a shaft 1623 of the rear wheel 162. A front end of the chain stay 115 in the longitudinal direction is connected to the bracket 116. A rear end of the chain stay 115 in the longitudinal direction is connected to a rear end of the seat stay 114. The pair of chain stays 115 are separated in the left-right direction, and the rear wheel 162 is rotatably attached to the rear end of the pair of chain stays 115 via a shaft 1623 that passes through a hub 1621. The rotation axis of the rear wheel 162 is approximately parallel to the running surface 100 and is the same as the central axis of the shaft 1623 that supports the rear wheel 162.

[0030] (2.1.5) Seat stays The pair of seat stays 114 are pipes that connect the pair of chain stays 115 and the seat tube 113. In the first embodiment, the rear ends of the seat stays 114 in the longitudinal direction are connected to the rear ends of the chain stays 115 in the longitudinal direction. The front ends of the seat stays 114 in the longitudinal direction are connected to the seat tube 113.

[0031] (2.1.6) Brackets The bracket 116 is a portion to which the drive unit 14 is attached. The longitudinal rear end of the down tube 112, the longitudinal lower end of the seat tube 113, and the longitudinal front end of the chain stay 115 are connected to the bracket 116. As a result, the longitudinal rear end of the down tube 112, the longitudinal lower end of the seat tube 113, and the longitudinal front end of the chain stay 115 are fixed to one another.

[0032] (2.2) Battery unit The battery unit 13 includes a battery 131 and a battery control unit (not shown).

[0033] The battery 131 supplies power to the drive unit 14. More specifically, the battery 131 supplies power to a motor 141 of the drive unit 14. The battery 131 also supplies power to the motor 141, as well as to, for example, the operating device 27, the headlight 6, and the taillight 7. The battery 131 is removably attached to the seat tube 113.

[0034] Each time the electric bicycle 1 is used, the battery control unit obtains the amount of power (battery power consumption) consumed by the battery 131 when the electric bicycle 1 is traveling (when in use). The battery control unit also manages the remaining charge of the battery 131. More specifically, the battery control unit obtains the difference between the remaining battery charge before use and the battery power consumption as the new remaining battery charge.

[0035] The remaining battery capacity is corrected taking into consideration the deterioration of the battery 131. The deterioration of the battery 131 can be obtained from a charge / discharge history indicating the charging / discharging of the battery 131. The charge / discharge history is stored together with the ID (Identification) of the battery 131.

[0036] (2.3) Drive unit The drive unit 14 includes a motor 141, a transmission mechanism 142, a crankshaft (rotating shaft) 143, and a case 144. The drive unit 14 is a device capable of outputting a driving auxiliary output. In the first embodiment, the drive unit 14 adds the driving auxiliary output to a pedaling force, which is a human-powered driving force, and transmits the added output to the rear wheel 162 via the power transmission body 23.

[0037] The motor 141 is configured to provide rotational power to the wheel 16 of the electric bicycle 1. The motor 141 constitutes a drive source that drives the wheel 16. The motor 141 is provided near the crankshaft 143 of the electric bicycle 1, is driven by electric power from the battery 131, and transmits power to the crankshaft 143.

[0038] The transmission mechanism 142 is composed of, for example, a plurality of gears, and functions as a reducer that reduces the speed of the driving force from the motor 141. The transmission mechanism 142 is connected to a crankshaft 143, and transmits the driving force from the motor 141 to the crankshaft 143 after reducing the speed.

[0039] A pair of crank arms 18 (see FIG. 2) are attached to the crankshaft 143 of the drive unit 14. The longitudinal direction of each crank arm 18 is a direction that intersects (is perpendicular to) the rotation axis of the crankshaft 143. The pair of crank arms 18 are aligned in a straight line when viewed in the direction of the rotation axis of the crankshaft 143.

[0040] The case 144 is formed into a box shape by, for example, die-cast aluminum. The motor 141, the transmission mechanism 142, the crankshaft 143, etc. are housed inside the case 144. That is, the case 144 houses the transmission mechanism 142.

[0041] (2.4) Cover The cover 15 is a wiring cover for covering the wiring group. The wiring group includes a power line connected to the battery 131, and a power line and a signal line connected to the operating device 27.

[0042] The cover 15 is made of a synthetic resin such as ABS (Acrylonitrile Butadiene Styrene) resin and has a flat box shape with one side open.

[0043] (2.5) Wheels The multiple wheels 16 are members that support the frame 11 above the riding surface 100. The electric bicycle 1 according to the first embodiment has a front wheel 161 and a rear wheel 162 as the multiple wheels 16. The front wheel 161 has a hub 1611 at its center. The rear wheel 162 has a hub 1621 at its center.

[0044] The front wheel 161 is the front wheel of the two wheels 16 arranged in the front-rear direction. In the first embodiment, the front wheel 161 is supported by the leg 211 so as to be rotatable about an axis along the left-right direction. In the first embodiment, the front wheel 161 is a wheel that does not receive power transmitted from the motor 141.

[0045] A front fender 25 that is curved along the circumferential direction of the front wheel 161 is provided above the front wheel 161. The front fender 25 functions as a mudguard that prevents water splashes or mud, etc., splashed up by the front wheel 161 from being splashed toward the user while the electric bicycle 1 is traveling.

[0046] The rear wheel 162 is the rear wheel of the two wheels 16 aligned in the front-rear direction. In the first embodiment, the rear wheel 162 is supported by a pair of chain stays 115 so as to be rotatable about an axis along the left-right direction.

[0047] The rear wheel 162 further has a rear sprocket 1622 that is concentric with the hub 1621 and is attached integrally to the hub 1621. The rear sprocket 1622 is connected to a drive sprocket (not shown) that is connected to the crankshaft 143 (see FIG. 2) of the drive unit 14 via the power transmission body 23. In this way, the power output from the drive unit 14 is transmitted to the rear wheel 162.

[0048] A rear fender 26 that is curved along the circumferential direction of the rear wheel 162 is provided above the rear wheel 162. The rear fender 26 functions as a mudguard that prevents water splashes or mud, etc., splashed up by the rear wheel 162 from being splashed toward the user while the electric bicycle 1 is traveling.

[0049] In addition, a locking device such as a circle lock is attached to the rear wheel 162. The locking device can be in any one of a locked state, an unlocked state, and an unlockable state. The locked state is a state in which the rotation of the rear wheel 162 is restricted to prohibit the electric bicycle 1 from traveling. The unlocked state is a state in which the rotation of the rear wheel 162 is not restricted to permit the electric bicycle 1 to travel. The unlockable state is a state in which the rotation of the rear wheel 162 is restricted to prohibit the electric bicycle 1 from traveling, but the state can be switched from the locked state to the unlocked state when an operation is received from the operating device 27. That is, in the locked state, the locking device cannot be switched to the unlocked state even if the user operates the operating device 27, but in the unlockable state, the locking device can be switched to the unlocked state when the user operates the operating device 27. In the first embodiment, when the electric bicycle 1 is not in use, the locking device is in the locked state as a rule.

[0050] (2.6) Saddle The saddle 17 has a seat pillar 171 and a portion 172 where the rider sits. The seat pillar 171 passes through the seat tube 113 along the central axis of the seat tube 113. The seat pillar 171 protrudes downward from the portion 172 where the rider sits in the saddle 17. In the first embodiment, the seat pillar 171 is inclined with respect to the riding surface 100 so as to move forward as it goes downward. The seat pillar 171 is attached to the seat tube 113 so as to be movable along the central axis of the seat tube 113.

[0051] (2.7) Pedals The pedal 19 is attached to an end 181 of each crank arm 18 in the longitudinal direction, the end opposite to the crank shaft (rotation shaft) 143. The pedal 19 is attached rotatably to the crank arm 18. The rotation shaft of the pedal 19 is approximately parallel to the rotation shaft of the crank shaft 143.

[0052] (2.8) Front fork The front fork 21 supports the front wheel 161. The front fork 21 includes a pair of legs 211, a crown 212, and a steering column 213. The crown 212 connects the upper ends of the pair of legs 211. The steering column 213 protrudes from the crown 212. The front wheel 161 is rotatably attached to the pair of legs 211 via a shaft that passes through a hub 1611. The rotation axis of the front wheel 161 is parallel to the running surface 100. The protruding direction (longitudinal direction) of the steering column 213 extends from the crown 212 so as to go rearward as it goes upward, and is inclined with respect to the running surface 100.

[0053] (2.9) Handle The handlebars 22 are attached to the upper end of the steering column 213 and fixed to the front fork 21. The handlebars 22 have a main bar 220 extending in the left-right direction, and grips 221 are formed on both ends of the main bar 220. In addition, brake levers 223 are provided on both ends of the main bar 220.

[0054] The steering column 213 passes through the head tube 111 of the frame 11 and is rotatably attached to the frame 11. The rotation axis of the steering column 213 is approximately parallel to the longitudinal direction of the steering column 213. Therefore, the handlebars 22 can rotate the front wheel 161 about an axis along the longitudinal direction of the steering column 213.

[0055] A front basket 24 for accommodating the user's belongings is attached above the connection between the handlebars 22 and the steering column 213. The front basket 24 is positioned above the front wheels 161 with a gap therebetween.

[0056] In addition, an operating device 27 is attached to the handle 22. The operating device 27 is attached near the center of the main body bar 220 via an attachment member 271 (see FIG. 3B) made of a band.

[0057] (2.10) Power transmission body The power transmission body 23 transmits the power output from the drive unit 14 to at least one of the multiple wheels 16. In the first embodiment, the power transmission body 23 is a chain that is stretched between a drive sprocket (not shown) connected to the crankshaft 143 of the drive unit 14 and a rear sprocket 1622 of the rear wheel 162 so as to be capable of transmitting power. However, in the present disclosure, the power transmission body 23 may be, for example, a belt, a shaft, a wire, or a gear.

[0058] (2.11) Operating device The operating device 27 is attached to the handle 22 of the electric bicycle 1. The operating device 27 has a power switch that is pressed by the user. The operating device 27 also has a switch that accepts an input to change the degree to which the motor 141 assists the user's pedaling force (pedaling power), and a display that displays parameters such as the remaining charge of the battery 131.

[0059] (2.12)Display device The display device 3 includes a vehicle body attachment portion 32, a turn signal light 4, a riding mode indicator light 5, and a case 30. The case 30 houses the turn signal light 4 and the riding mode indicator light 5. The display device 3 is attached to the vehicle body (bicycle main body 10) via the vehicle body attachment portion 32.

[0060] The case 30 (display device 3, body mounting portion 32) is attached to a portion of the body other than the handlebars 22. Here, the bicycle main body 10 (body) includes the front basket 24, the rear carrier 29 located above the rear wheel 162, the front fender 25, the rear fender 26, etc.

[0061] (2.13) Turn signal light The turn signal lights 4 constitute so-called turn indicators that indicate whether the electric bicycle 1 is turning right or left, and include a left turn signal light 4 that indicates a left turn, and a right turn signal light 4 that indicates a right turn. The left turn signal light 4 is located on the left side of the bicycle body 10 (body), and the right turn signal light 4 is located on the right side of the bicycle body 10 (body).

[0062] The direction indicator light 4 has a light-emitting unit such as a light bulb or an LED (Light Emitting Diode). The direction indicator light 4 has a reflector, but may not have a reflector. The light emitted from the light-emitting unit of the direction indicator light 4 is emitted to a predetermined range including the front from a predetermined opening window formed in the case 30. The light emitted from the direction indicator light 4 is an orange flashing light.

[0063] When the electric bicycle 1 turns left, the light emitted from the left turn signal light 4 flashes, and no light is emitted from the right turn signal light 4. When the electric bicycle 1 turns right, the light emitted from the right turn signal light 4 flashes, and no light is emitted from the left turn signal light 4.

[0064] (2.14) Driving mode indicator light The riding mode indicator light 5 indicates that the electric bicycle 1 (self-propelled vehicle) is riding in a specific riding mode so that people around can easily identify it. In recent years, specific small motorized bicycles (hereinafter, "specific small vehicles") have been riding on public roads. Specified small vehicles have two riding modes: a roadway riding mode (maximum speed 20km / h) that allows riding on roads, and a sidewalk riding mode (maximum speed 6km / h) that allows riding on sidewalks.

[0065] As a safety feature for this purpose, vehicles (specific small vehicles) are required to be equipped with a maximum speed indicator light (driving identification light or driving mode indicator light, hereafter referred to as driving mode indicator light) that informs those around them of the mode in which the vehicle is currently driving.

[0066] The driving mode indicator light 5 has a light-emitting unit such as a light bulb or an LED (Light Emitting Diode). The driving mode indicator light 5 has a reflector, but may not have a reflector. The light emitted from the light-emitting unit of the driving mode indicator light 5 is emitted to a predetermined range including the front from a predetermined opening window formed in the case 30. The light emitted from the driving mode indicator light 5 is green light.

[0067] The left driving mode indicator light 5 and the right driving mode indicator light 5 are lit when indicating the "roadway driving mode" and flash when indicating the "sidewalk driving mode".

[0068] In the first embodiment, the opening window through which the light emitted from the direction indicator lamp 4 exits and the opening window through which the light emitted from the driving mode indicator lamp 5 exits are the same.

[0069] When the electric bicycle 1 turns left, the light emitted from the left turn signal light 4 flashes, and at this time, no light is emitted from the left driving mode indicator light 5, and only the right driving mode indicator light 5 is emitted.

[0070] In addition, when the electric bicycle 1 turns right, the light emitted from the right turn signal light 4 flashes, and at this time, no light is emitted from the right driving mode indicator light 5, and only the left driving mode indicator light 5 is emitted.

[0071] (2.15) Case In the first embodiment, the case 30 includes a front case 301 and a rear case 302. The front case 301 houses a front direction indicator light 41 constituting the direction indicator light 4, and a front driving mode indicator light 51 constituting the driving mode indicator light 5. The rear case 302 houses a rear direction indicator light 42 constituting the direction indicator light 4, and a rear driving mode indicator light 52 constituting the driving mode indicator light 5. In this way, since the display device 3 includes the front case 301 and the rear case 302 as the case 30, it becomes easier to arrange the front display device 3 and the rear display device 3 in appropriate positions.

[0072] Furthermore, in the first embodiment, the case 30 includes a left case 30 and a right case 30. The left case 30 houses the left direction indicator light 4 that constitutes the direction indicator light 4, and the left driving mode indicator light 5 that constitutes the driving mode indicator light 5. The right case 30 houses the right direction indicator light 4 that constitutes the direction indicator light 4, and the right driving mode indicator light 5 that constitutes the driving mode indicator light 5. In this way, by the display device 3 having the left case 30 and the right case 30 as the cases 30, it becomes easier to arrange the left display device 3 and the right display device 3 in appropriate positions, respectively.

[0073] (2.16) Summary of the first embodiment The vehicle body attachment portion 32 (display device 3) is attached to a portion of the vehicle body other than the handlebars 22. This prevents the light from the display device 3 from being blocked by the hands or arms gripping the grips 221 of the handlebars 22.

[0074] 3A, in the first embodiment, the rear case 302 (rear display device 3) is located between the left and right grips 221. This prevents the light from the display device 3 from being blocked by the hand or arm gripping the grip 221.

[0075] 1 and 3A, in the first embodiment, the headlights 6 and taillights 7 are located between the left case 30 and the right case 30. This prevents the headlights 6 and taillights 7 from emitting light from the same position as the display device 3, making it easy to distinguish between the light emitted from the headlights 6 or taillights 7 and the light emitted from the display device 3.

[0076] In the first embodiment, as shown in Fig. 1, the front case 301 is located between the front wheel 161 and the front basket 24. The front case 301 is attached to the bicycle main body 10 (body) via a body attachment part 32. The body attachment part 32 is a bracket 321 attached to the body (specifically, the front basket 24). Since only the headlight 6 is normally located between the front wheel 161 and the front basket 24, by arranging the front case 301 (display device 3) between the front wheel 161 and the front basket 24, it does not interfere with the arrangement of components other than the headlight 6.

[0077] In the first embodiment, as shown in Fig. 3A, the rear case 302 is attached to the bicycle main body 10 (body) via a mounting bar 8 serving as the body mounting portion 32. The rear case 302 is attached to the mounting bar 8. The mounting bar 8 is attached to the rear carrier 29 (body). That is, the rear case 302 is attached to the rear carrier 29 via the mounting bar 8.

[0078] The rear case 302 is attached to the lower side of the rear carrier 29 , and the upper surface of the rear case 302 is covered by the rear carrier 29 .

[0079] In this manner, by attaching the cases 30 to the mounting bar 8, the left case 30 and the right case 30 can be attached together by the mounting bar 8.

[0080] In addition, because the upper surface of the rear case 302 is covered by the rear carrier 29, the rear case 302 is less likely to be damaged even if the electric bicycle 1 falls over, etc.

[0081] (3) Overview Second embodiment An overview of the electric bicycle 1 and display device 3 according to the second embodiment will be described with reference to Figures 4 to 6B. Note that since the electric bicycle 1 and display device 3 according to the second embodiment are largely the same as the electric bicycle 1 and display device 3 according to the first embodiment, a description of the common parts will be omitted and differences will be mainly described.

[0082] Compared with the display device 3 according to the first embodiment, the display device 3 does not include the vehicle body attachment portion 32, but instead includes an inter-grip attachment portion 31.

[0083] The inter-grip attachment portion 31 is attached to a portion 222 between the grips 221 at both ends of a main body bar 220 of the handlebar 22 of the vehicle body. The inter-grip attachment portion 31 is made of a band (see FIG. 6B).

[0084] Furthermore, compared to the display device 3 according to the first embodiment, the electric bicycle 1 (self-propelled vehicle) does not have a front basket 24, but instead has a front carrier 28 located above the front wheel 161. A front case 301 is attached to the front carrier 28. To explain further, the front case 301 is attached to the lower side of the front carrier 28, and the upper surface of the front case 301 is covered by the front carrier 28.

[0085] By attaching the inter-grip mounting portion 31 to the portion 222 between the grips 221, even when the display device 3 is attached to the handle 22, the light from the display device 3 is prevented from being blocked by the hand or arm gripping the grip 221 of the handle 22.

[0086] In addition, since the upper surface of the front case 301 is covered by the front carrier 28, the front case 301 is less likely to be damaged even if the electric bicycle 1 falls over, etc.

[0087] (4) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. Below, modified examples of the above-described embodiment are listed. The modified examples described below can be applied in appropriate combination.

[0088] (4.1) Variation 1 In the first and second embodiments, the autonomous vehicle is an electric bicycle 1, but in Modification 1, as shown in Fig. 7, the autonomous vehicle is an electric kickboard 1A. The electric kickboard 1A includes wheels 16 (front wheel 161 and rear wheel 162), a board body 10A, and a drive unit (not shown) similar to that of the electric bicycle 1, and a display device 3 is attached to a portion 222 between grips 221 at both ends of a main body bar 220 of a handlebar 22 of the electric kickboard 1A. In the electric kickboard 1A, the drive unit drives (including adjusting the driving force) and stops the wheels 16 by rotating the grip 221.

[0089] As a result, even when the display device 3 is attached to the handle 22 of the electric kickboard 1A, the light from the display device 3 is prevented from being blocked by the hands or arms gripping the grips 221 of the handle 22.

[0090] (4.2) Variation 2 As shown in Fig. 8, the electric bicycle 1 according to the second modification is the electric bicycle 1 according to the first embodiment without the crank arm 18 and the pedal 19. In the electric bicycle 1 according to the second modification, similar to the electric kickboard 1A according to the first modification, the drive unit 14 drives and stops the wheel 16 (including adjusting the driving force) by rotating the grip 221.

[0091] This prevents the light from the display device 3 from being blocked by the hands or arms gripping the grips 221 of the handle 22.

[0092] (4.3) Variation 3 9, the electric bicycle 1 according to the third modification is the electric bicycle 1 according to the second embodiment without the crank arm 18 and the pedals 19. In the electric bicycle 1 according to the third modification, similar to the electric kickboard 1A according to the first modification, the drive unit 14 drives and stops the wheel 16 (including adjusting the driving force) by rotating the grip 221.

[0093] As a result, even when the display device 3 is attached to the handlebars 22 of the electric bicycle 1, the light from the display device 3 is prevented from being blocked by the hands or arms gripping the grips 221 of the handlebars 22.
