The connection portion 10 and the connection portion 11 are connectors that can electrically connect the plurality of vehicles 1, and in the case of the present embodiment, are connectors that can mechanically connect the plurality of vehicles 1. The connection portion 10 is disposed on the front side of the vehicle 1, and the connection portion 11 is disposed on the rear side of the vehicle 1. The connection portion 10 and the connection portion 11 are configured to be capable of being mutually inserted and removed, thereby mechanically and electrically connecting the plurality of vehicles 1 to each other.
Fig. 4A is a perspective view of the connection portion 10, and fig. 4B is a perspective view of the connection portion 11. In the present embodiment, the connection portion 10 is formed in a convex shape, and the connection portion 11 is formed in a concave shape, so that the connection portion 10 is inserted into the connection portion 11, but the opposite configuration may be adopted. The connection portion 10 has electrical connection terminals (electrodes) T1 to T3 at its tip end portion. The terminals T1 and T2 are terminals for power supply. The power supply method of the present embodiment is a method of supplying a dc voltage to the terminal T1 and the terminal T2, the terminal T1 being a positive electrode, and the terminal T2 being a negative electrode (ground). The terminal T3 is a terminal for a communication line. Communication between the vehicle 1 and a system (vehicle management device 204) described later, and communication between the vehicles 1 can be performed via the terminal T3.
The connection portion 10 has a groove 10a formed from the front end portion thereof toward the rear. A lock key 13a of a lock unit 13 described later is disposed in the groove 10a so as to be movable. An opening (recess) 11a for receiving the connection portion 10 is formed at an end of the connection portion 11, and an engagement wall 11b is provided on a rear side of the opening 11a, and the engagement wall 11b is inserted into the groove 10a and engaged with the lock unit 13.
The connection portion 10 is further provided with a display portion 12 that displays individual information for specifying the vehicle 1. The display unit 12 is formed by a stamp or a sticker on the surface of the member, and displays a code indicating individual information.
Fig. 5A to 5D are explanatory views of connection, locking, and unlocking of the connection portion 10 and the connection portion 11, and are plan views of the connection portion 10 and the connection portion 11. The connection 11 is illustrated as a cross-sectional view. In the drawing, the terminal T3 of the connection portion 10 is located at a position overlapping with the terminal T1, and therefore illustration thereof is omitted. The connection portion 11 has a back wall 11d formed on the back side of the opening 11a, and electrical connection terminals (electrodes) T11 and T12 corresponding to the terminals T1 and T2 are arranged therein. An electrical connection terminal (electrode) T13 corresponding to the terminal T3 is also provided on the back wall 11D, but the illustration thereof is omitted in fig. 5A to 5D.
As shown in fig. 5A, the main body 13b of the lock unit 13 is disposed inside the connecting portion 10, and the lock key 13a protrudes from the main body in a direction crossing the groove 10a. The lock unit 13 of the present embodiment is a solenoid-type actuator, and the main body 13b includes a return spring that biases the lock key 13a to the lock position shown in fig. 5A, and an electromagnetic solenoid (neither of which is shown) that pulls the lock key 13a into the main body 13b. An inclined surface is formed on the open end side of the groove 10a of the lock key 13 a.
In connection between the connection portion 10 and the connection portion 11, the connection is performed by pressing the connection portion 10 toward the connection portion 11 (or pressing the connection portion 11 toward the connection portion 10). Fig. 5B shows a state in which the connecting portion 10 is pressed into the connecting portion 11. When the connection portion 10 is inserted into the opening 11a of the connection portion 11, the engagement wall 11b enters the groove 10a. By bringing the tip of the engagement wall 11b into contact with the inclined surface of the lock key 13a, a force is generated in the direction of the main body 13b in the lock key 13a as indicated by an arrow, and the lock key 13a is pushed into the main body 13b against the urging force of the return spring.
As shown in fig. 5C, when the front end portion of the connection portion 10 reaches the back wall 11d of the connection portion 11, the mechanical connection between the connection portion 10 and the connection portion 11 is completed, and in addition, the terminals T1 to T3 are brought into contact with the corresponding terminals T11 to T13, so that the electrical connection between the connection portion 10 and the connection portion 11 is completed. Further, a spring for biasing one terminal toward the other terminal may be provided in at least one group of the terminals T1 to T3 and the corresponding terminals T11 to T13 to stabilize the contact state.
The engagement wall 11b is formed with an engagement portion 11c into and from which the lock key 13a can be moved. In the present embodiment, the engaging portion 11c is a hole penetrating the engaging wall 11b in the thickness direction. In the stage of fig. 5C, the lock key 13a is located at a position facing the engagement portion 11C, and the lock key 13a is returned to the lock position as indicated by an arrow by the urging force of the return spring of the lock unit 13. The lock key 13a enters the engagement portion 11c, and the connection between the connection portion 10 and the connection portion 11 is locked, so that the connection portion 10 cannot be detached from the connection portion 11. The connection state between the plurality of vehicles 1 can be maintained more reliably. In addition, unlocking is required when the vehicle 1 is taken out, and theft and the like can be suppressed.
When the lock by the lock unit 13 is released, the electromagnetic solenoid of the main body 13b is driven, and the lock key 13a is pulled into the main body 13b. Fig. 5D shows the release mode. The locking key 13a is moved in the arrow direction by the actuation of the electromagnetic solenoid of the main body 13b, and is pulled into the main body 13b, thereby being disengaged from the engagement portion 11c of the engagement wall 11 b. This enables the connection portion 10 to be separated from the connection portion 11.
In the present embodiment, the lock key 13a is biased to the lock position by the return spring, and the lock key 13a is pulled to the release position by the driving of the electromagnetic solenoid. That is, the lock key 13a may be biased to the release position by a return spring, and the lock key 13a may be moved to the lock position by driving the electromagnetic solenoid. The locking means 13 may be a mechanism other than an electromagnetic solenoid type mechanism, for example, a mechanism in which a motor that performs both locking and unlocking is used as a driving source.
Next, the configuration of the electrical system such as the control unit 7 will be described with reference to fig. 6. Fig. 6 is a block diagram of the circuit of the vehicle 1. The control unit 7 includes a processing unit 70, a storage unit 71 such as RAM and ROM, an interface unit 72 (I/F unit) 72 for relaying transmission and reception of signals between the external device and the processing unit 70, a charging circuit 73 for charging the battery 8, and a driving circuit 74 for driving the motor 61 and the lock unit 13. The processing unit 70 is a processor typified by a CPU, and executes a program stored in the storage unit 71 to control the motor 61 and the lock unit 13. The power required for driving the motor 61 and the lock unit 13 is supplied from the battery 8.
The control unit 7 is connected to a sensor 14 and a communication circuit 15. The sensor 14 includes, for example, a sensor that detects a pedal force of a user and a sensor that detects a vehicle speed of the vehicle 1, and can control driving (assist amount) of the motor 61 based on a detection result of the sensor 14. The communication circuit 15 is a circuit capable of performing short-range wireless communication with a portable terminal 220 such as a smart phone. The user can give an instruction to release the lock unit 13 from the mobile terminal 220. Further, communication can be performed via an external server or the like.
The terminals T1 to T3 of the connection portion 10 and the terminals T11 to T13 of the corresponding connection portion 11 are electrically connected to each other through the wires W1 to W3 inside the vehicle 1. The wiring W1 functions as a power supply line, the wiring W2 functions as a ground line, and the wiring W3 functions as a communication line. The wiring W1 and the wiring W2 can be used for external power supply for charging the battery 8 via the charging circuit 73. The wiring W3 is used for communication between the vehicle 1 and a system (vehicle management device 204) described later, or communication between the vehicles 1, for example, via the I/F unit 72.
(charging System)
Next, an example of a connection method between the vehicles 1 will be described with reference to fig. 3 and 7. Fig. 7 is a diagram showing an example of a charging system 200 using the vehicle 1.
As shown in fig. 3, in the folded state of the vehicle 1, the front frame 30 and the intermediate frame 32 are formed in a mountain-folded state about the shaft member 33, and the pedal 4, the pedal arm 4a, and the arm 38b are in a posture of standing up in the substantially D3 direction. The front frame 30 and the head pipe 2 are formed in a valley-folded state centering on the shaft member 30 b. The slide member 31a slides toward the upper end of the head pipe 2, and the sub-frame 31 and the front frame 30 are formed in a valley-folded state centering on the shaft member 31 c. The seat frame 34 is rotated about the shaft member 35a and the shaft member 36a with respect to the sub-frame 35 and the sub-frame 36, and the seat tube 34a is set in a posture of being raised in the substantially D3 direction.
The connection portion 10 and the connection portion 11 are disposed at portions exposed to the outside in the folded state, and are disposed at the same height H1 from the ground surface of the vehicle 1 (the contact surfaces of the front wheels FW and the rear wheels RW with the ground in the present embodiment) in the folded state. That is, in the folded state of the vehicle 1, the connection portion 10 of one vehicle 1 and the connection portion 11 of the other vehicle 1 are exposed so as to be connectable to each other, and the connection heights are the same, so that easy connection work is realized.
In the present embodiment, the connection portion 10 and the connection portion 11 are disposed at a portion that is exposed to the outside in the unfolded state, but one or both of the connection portion 10 and the connection portion 11 may be disposed at a portion that is not exposed to the outside in the unfolded state and exposed to the outside in the folded state.
The connecting portion 10 and the connecting portion 11 are connected to each other in the direction D1, and the connecting portion 10 of the other vehicle 1 is mechanically connected to the connecting portion 11 of the one vehicle 1, whereby the plurality of vehicles 1 can be connected in a row in the direction D1 as shown in fig. 7. By setting the insertion/extraction direction to the D1 direction, the traveling direction of the vehicle 1 is the same as the insertion/extraction direction, and the connection work between the connection portion 10 and the connection portion 11 can be easily performed while pushing the vehicle 1. Since the vehicle 1 is a three-wheeled bicycle having one front wheel FW and two rear wheels RW, the vehicle has high free-standing stability, and the entire train is stably free-standing. In addition, as shown in fig. 3, in the folded state, the vehicle 1 is in a posture in which the front wheels FW are located between the two rear wheels RW, and the length thereof in the D1 direction becomes short. In the same manner as in the vehicle train shown in fig. 7, since the following vehicle 1 is aligned between the two rear wheels RW of the vehicle 1 whose front wheels FW are located on the front side thereof, the vehicle train can be formed shorter.
As shown in fig. 7, when a plurality of vehicles 1 are mechanically connected in a row, the plurality of vehicles 1 are also electrically connected. The charging system 200 has an external power supply 201. In the illustrated example, the external power supply 201 has a form of a charging port provided upright on the ground. The external power supply 201 has a connection portion 202. The connection portion 202 has the same structure as the connection portion 11 of the vehicle 1, and includes electric connection terminals (electrodes) T21 to T23 corresponding to the terminals T11 to T13 and engagement walls corresponding to the engagement walls 11 b. As shown in fig. 3, the connection portion 202 is located at the same height H1 as the connection portion 10 and the connection portion 11 of the vehicle 1 in the folded state.
The terminals T21 and T22 of the connection unit 202 are connected to a dc power supply circuit 203 that receives power supply from the electric power system, and can supply dc power to the vehicle 1. As shown in fig. 7, the connection portion 10 of the vehicle 1 located at the forefront in the train of the vehicle 1 as seen from the external power supply 201 is mechanically and electrically connected to the connection portion 202 of the external power supply 201, whereby all the following vehicles 1 are also electrically connected in parallel to the external power supply 201. Thus, each of the batteries 8 of the plurality of vehicles 1 can be charged simultaneously by one external power supply 201. Thus, more charging of the battery 8 of the vehicle 1 can be performed in less space.
(example of rental System)
The terminal T23 of the connection unit 202 is connected to the vehicle management device 204, and the system-side vehicle management device 204 can communicate with the control unit 7 of each vehicle 1. The vehicle management device 204 is a computer that manages the vehicle 1 connected to the external power supply 201. Vehicle management device 204 is disposed at each site (in other words, a site of a rental service) of charging system 200, and information of each site is managed by a higher-level server. Fig. 8 is a block diagram of an information management system.
Each vehicle management device 204 is connected to the management server 210 via a communication network 211 such as the internet so as to be communicable. The management server 210 has a database 210a storing information of users who wish to rent the vehicle 1 and information of the vehicle 1. The user can access the management server 210 from the own mobile terminal 220 via the communication network 211, and perform a registration in advance for vehicle rental, an application in the case of actually renting the vehicle 1, and the like.
Next, a process of the vehicle management device 204 and the like will be described. First, an example of identification of a train of vehicles in the vehicle management device 204 will be described. The user returning the rented vehicle 1 connects the returning vehicle to the external power supply 201 or the end of the train of vehicles connected to the external power supply 201. The vehicle management device 204 periodically transmits a response request signal from the terminal T23, for example. The control unit 7 of each vehicle 1 electrically connected to the external power supply 201 returns a response signal including individual information of itself to the response request signal. In the case where none of the vehicles 1 electrically connected to the external power supply 201 exists, a response signal to the response request signal is not returned.
If the vehicle 1 (the preceding vehicle) is connected to the external power supply 201, the control unit 7 of the preceding vehicle receives the response request signal. Then, the control unit 7 of the front vehicle transmits individual information of the front vehicle from the terminals T3, T13 for responding to the request signal. The vehicle management device 204 recognizes that the vehicle 1 is connected to the external power supply 201 based on the received individual information, and updates the vehicle management information with the vehicle having received the individual information as the head-end vehicle. The vehicle management information is information stored in the storage portion 71. The vehicle management device 204 notifies the management server 210 that the head-end vehicle having received the individual information is returned, and the management server 210 updates the database 210a with respect to the usage information of the vehicle 1. The control unit 7 of the front vehicle can start charging of the battery 8 by the charging circuit 73.
When the preceding vehicle connects to the second vehicle 1 (the following vehicle), the control unit 7 of the following vehicle receives a response request signal from the vehicle management device 204, and transmits individual information of the following vehicle from the terminals T3 and T13 for the response request signal. The vehicle management device 204 recognizes that the following vehicle 1 is connected to the preceding vehicle 1 based on the received individual information, and manages the vehicle as the second vehicle of the train. The vehicle management device 204 notifies the management server 210 that the following vehicle having received the individual information is returned, and the management server 210 updates the database 210a with respect to the usage information of the vehicle 1. The control unit 7 of the following vehicle can start charging of the battery 8 by the charging circuit 73. In the following, by performing the same process every time a following vehicle is connected, the connection order of each vehicle 1 of the vehicle train can be managed.
The processing unit 70 of the control unit 7 may start charging the battery 8 by the charging circuit 73 on condition that the locking unit 13 is locked to the external power supply 201 or the other vehicle 1. With the locking, the vehicle 1 can be prevented from being disconnected from the external power supply 201 or other vehicles 1 and the charging can be stopped, and the battery 8 can be charged more reliably. Whether or not the lock is locked may be determined based on a detection result of a sensor that detects an operation state of the lock unit 13, for example. Alternatively, in the configuration in which the lock unit 13 is brought into the locked state by the driving of the actuator, the processing unit 70 may start charging by assuming that the lock is established when a control command to bring the lock unit 13 into the locked state is output.
Next, an example of processing by the vehicle management device 204 in a case where the vehicle 1 is separated from the train connected to the external power supply 201 (a case where the vehicle 1 is leased) will be described.
The user selects a vehicle 1 (rental vehicle) to be used from among the vehicle trains connected to the external power supply 201, and inputs the individual information displayed on the display unit 12 thereof to the own portable terminal 220. The input can be made by, for example, manual input or scanning of a code (image reading). The user accesses the management server 210 through the portable terminal 220 and transmits a rental request together with the individual information of the rental target vehicle. Further, the above-described process can be easily performed by installing a dedicated application provided by the provider of the rental service in the portable terminal 220 in advance.
The management server 210 immediately transmits the rental license key of the rental object vehicle to the portable terminal 220. The rental license key is an unlocking key for unlocking the lock unit 13. The user transmits the received release key and the individual information of the rental object vehicle from the portable terminal 220 to the control unit 7 of the rental object vehicle. The control unit 7 recognizes that itself is selected based on the received individual information, and checks whether the rental license key stored in the storage portion 71 coincides with the received rental license key. In the case of agreement, the rental of the rental object vehicle should be permitted, and the individual information of the rental object vehicle and the separation permit request should be transmitted to the vehicle management device 204.
When a following vehicle is not connected to the rental vehicle (when the rental vehicle is the last vehicle), the vehicle management device 204 notifies the control unit 7 of the rental vehicle of the lock release permission. If the battery 8 is being charged, the control unit 7 of the rental-target vehicle releases the lock of the lock unit 13, while stopping the charging. Thus, the user can use the rental object vehicle. In addition, by releasing the lock after stopping the charging, the electric safety can be improved. The vehicle management device 204 notifies the management server 210 that the rental-target vehicle has been rented by the user, and the management server 210 updates the database 210a with respect to the usage information of the vehicle 1.
In the case where a following vehicle is connected to the rental object vehicle, the vehicle management device 204 notifies the control unit 7 of the following vehicle of the lock release instruction. The control unit 7 of the following vehicle releases the lock of the locking unit 13, thereby separating the following vehicle from the rental object vehicle. Next, the vehicle management device 204 notifies the control unit 7 of the rental target vehicle of the lock release permission. If the battery 8 is being charged, the control unit 7 of the rental-target vehicle releases the lock of the lock unit 13, while stopping the charging. Thus, the user can use the rental object vehicle. In addition, by releasing the lock after stopping the charging, the electric safety can be improved. In addition, in a case where a following vehicle is connected to the rental vehicle, the user performs a job of connecting the following vehicle to the preceding vehicle to which the rental vehicle was connected or to the external power supply 201. The vehicle management device 204 recognizes that the rental target vehicle is released, and the following vehicle is connected to the preceding vehicle or the external power supply 201, based on the response of the control unit 7 of the following vehicle to the response request, and updates the vehicle management information. In addition, the vehicle management device 204 notifies the management server 210 that the rental target vehicle has been rented by the user, and the management server 210 updates the database 210a with respect to the usage information of the vehicle 1.
Further, information of the connection order of the respective vehicles 1 of the vehicle train among the vehicle management information held by the vehicle management device 204 may be stored/updated in the storage portion 71 of the control unit 7 of the respective vehicles 1 forming the vehicle train by communication, and shared among the vehicles 1. By sharing the information of the connection order, the control unit 7 of the rental object vehicle can determine the following vehicle connected to itself. Accordingly, in the case where the rental license key is received from the portable terminal 220 of the rental target vehicle user, the control unit 7 does not need to transmit the separation license request to the vehicle management apparatus 204.
For example, if a following vehicle is not connected to the rental-target vehicle, if the battery 8 is being charged, the control unit 7 of the rental-target vehicle releases the lock of the lock unit 13 while stopping the charging. Thus, the user can use the rental object vehicle.
In addition, in a case where a following vehicle is connected to the rental-target vehicle, the control unit 7 of the rental-target vehicle notifies the control unit 7 of the following vehicle of the lock release instruction. The control unit 7 of the following vehicle releases the lock of the locking unit 13, thereby separating the following vehicle from the rental object vehicle. Next, if the battery 8 is being charged, the control unit 7 of the rental-target vehicle releases the lock of the lock unit 13 on the basis of stopping the charging. Thus, the user can use the rental object vehicle.
< second embodiment >
In the first embodiment, an example of the vehicle 1 as a tricycle is described, but in the present embodiment, an example of a two-wheeled electric power assisted bicycle is described.

The seat post 134a is supported by the seat tube 134 so as to be movable in the axial direction thereof, and a user can adjust the height of a saddle 134b supported by the upper end portion of the seat post 134a to fix the seat post 134a to the seat tube 134. A handle 134c that can be gripped by a user is fixed to the rear portion of saddle 134 b. The main frame 133 integrally includes the connection portion 111.
The main frame 133 is swingably coupled to a rear frame 138 via a shaft member 133 b. The rear frame 138 supports the drive transmission mechanism 105, the electric unit 106, and the rear wheel RW. The rear frame 138 includes two arms 138b extending rearward. The two arms 138b rotatably support the rear wheel RW.
The vehicle 101 of the present embodiment is a crank-type bicycle, one end of a left and right crank 104a is connected to a rotation shaft 151 of a drive transmission mechanism 105, and a pedal 104 is connected to the other end of each crank 104 a. The user rotates the rotation shaft 150 by alternately pressing the left and right pedals 104.
A rotating body (e.g., a pulley or sprocket) 152 is mounted on the rotating shaft 150. The rotation of the rotating body 152 is transmitted to a rotating body (e.g., a pulley or sprocket) 54 provided on a drive shaft of the rear wheel RW via a one-way clutch via an endless member (e.g., a belt or chain) V3.
The electric unit 106 includes a motor 106a and a transmission mechanism (e.g., belt transmission mechanism, gear device) not shown that transmits a driving force of the motor 106a to the rotation shaft 150. The motor 106a is driven by supplying electric power from the battery 108 to the motor 106a, so that the motor 106a exerts propulsion of the vehicle 101. The motor 106a of the present embodiment functions as a booster motor that assists the user's manpower during the running of the vehicle 101.
A side bracket 139 is provided on the left arm 13 b. A roller 139a that contacts the ground is rotatably attached to the front end of the side bracket 139.
The connection portions 110 and 111 have the same structure as the connection portions 10 and 11 in the first embodiment. The control unit 107 is also the same structure as the control unit 7 in the first embodiment.
As shown in fig. 11, in the folded state of the vehicle 101, the main frame 130 and the rear frame 138 are formed in a mountain-folded state centering on the shaft member 133 b. The front upper frame 131 and the upper tube 130a, and the front lower frame 132 and the lower tube 130b are formed in a mountain-folded state. In the vehicle 101, the front wheels FW and the rear wheels RW are arranged offset in the D2 direction, and in their folded state, the front wheels FW and the rear wheels RW of the vehicle 101 partially overlap in the D2 direction, and the length thereof in the D1 direction becomes short. In the folded state, the side stand 139 is in contact with the ground, and in the folded state, the vehicle 101 is stably free-standing.
The connection portion 110 and the connection portion 111 are disposed at portions exposed to the outside in the folded state, and are disposed at positions at the same height H2 from the ground surface of the vehicle 101 (the contact surfaces between the front wheels FW and the rear wheels RW and the rollers 139a of the side brackets 139 and the ground surface in the present embodiment) in the folded state. That is, in the folded state of the vehicles 101, the connection portion 110 of one vehicle 101 and the connection portion 111 of the other vehicle 101 are exposed so as to be capable of being connected to each other.
The roller 139a at the end of the side bracket 139 may be configured to be rotatable only when the side bracket 139 is lifted upward as in the traveling state. That is, in the folded state of the vehicle 101, the roller 139a is rotatably provided, and movement of the vehicle 101 in the folded state can be facilitated. On the other hand, when parking the vehicle 101 with the side stand 139 lowered in the extended state, the roller 139a does not rotate, and thus the stability during parking can be improved.
The connecting portion 110 and the connecting portion 111 are connected to each other in the direction D1, and the connecting portion 110 of one vehicle 101 is mechanically connected to the connecting portion 111 of the other vehicle 101, whereby a vehicle train similar to the vehicle train of the vehicle 1 according to the first embodiment shown in fig. 7 can be formed.
