It may be arranged at a site and exposed to the outside in a folded state.

The connecting portion 10 and the connecting portion 11 are inserted and pulled out in the D1 direction. By mechanically connecting the connecting portion 10 of another vehicle 1 to the connecting portion 11 of one vehicle 1, the D1 direction as shown in FIG. A plurality of vehicles 1 can be connected to each other in a row. Since the insertion/removal direction is the D1 direction, the traveling direction of the vehicle 1 is the same as the insertion/removal direction, and the connection work between the connecting portions 10 and 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, it has high self-supporting stability, and the vehicle train as a whole stably stands on its own. Further, as shown in FIG. 3, in the folded state, the vehicle 1 assumes a posture in which the front wheels FW are positioned between the two rear wheels RW, and the length in the D1 direction is shortened. Similarly, in the vehicle row shown in FIG. 7, the vehicle row can be made shorter because the front wheels FW of the following vehicle 1 are positioned between the two rear wheels RW of the vehicle 1 on the front side.

When a plurality of vehicles 1 are mechanically connected in a row as shown in FIG. 7, the plurality of vehicles 1 are also electrically connected. Charging system 200 has an external power source 201 . In the illustrated example, the external power supply 201 has the form of a charging port erected on the ground.

As shown in FIG. 7, the connecting portion 10 of the leading car 1 in the train of cars 1 as viewed from the external power source 201 is mechanically and electrically connected to the connecting portion 202 of the external power source 201. All subsequent vehicles 1 are also electrically connected in parallel with the external power supply 201 . Thereby, each battery 8 of a plurality of vehicles 1 can be charged simultaneously by one external power source 201 . Therefore, more batteries 8 of vehicles 1 can be charged in a smaller space.

(Example of rental system)
A terminal T23 in the connecting portion 202 is connected to the vehicle management device 204, and the vehicle management device 204 on the system side and the control unit 7 of each vehicle 1 can communicate with each other. Vehicle management device 204 is a computer that manages vehicle 1 connected to external power supply 201 . Vehicle management device 204 is arranged at each base of charging system 200 (in other words, base of rental service), and information on each base is managed by a host server. FIG. 8 is a block diagram of an information management system.

Each vehicle management device 204 is communicably connected to a management server 210 via a communication network 211 such as the Internet. The management server 210 has a database 210a in which information on users who wish to rent the vehicle 1 and information on the vehicle 1 are stored. The user can access the management server 210 from his/her mobile terminal 220 via the communication network 211 to perform pre-registration for vehicle rental, application for actually renting the vehicle 1, and the like.

Next, processing of the vehicle management device 204 and the like will be described. First, an example of recognizing a train of vehicles in the vehicle management device 204 will be described. A user who returns the rented vehicle 1 connects the vehicle to be returned to the end of the external power supply 201 or a 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 its own individual information in response to the response request signal. If there is no vehicle 1 electrically connected to the external power supply 201, no response signal is returned to the response request signal.

When the vehicle 1 (leading vehicle) is connected to the external power supply 201, the control unit 7 of the leading vehicle receives the response request signal. In response to the response request signal, the control unit 7 of the leading vehicle transmits individual information of the leading vehicle from terminals T3 and T13. The vehicle management device 204 recognizes that the vehicle 1 is connected to the external power source 201 from the received individual information, and updates the vehicle management information with the vehicle receiving the individual information as the leading vehicle. Vehicle management information is information accumulated in the storage unit 71 . Further, the vehicle management device 204 notifies the management server 210 that the lead vehicle for which the individual information has been received is returned, and the management server 210 updates the database 210a with the usage information of the vehicle 1 . The control unit 7 of the leading car can start charging the battery 8 by means of the charging circuit 73 .

Note that these processes can be easily performed by installing a dedicated application provided by the rental service provider on the mobile terminal 220 in advance.

The management server 210 transmits the rental permission key of the vehicle to be rented back to the mobile terminal 220 . The rental permission key is an unlock key for unlocking the lock unit 13 . The user transmits the received release key and the individual information of the vehicle to be rented from the mobile terminal 220 to the control unit 7 . The control unit 7 recognizes that it is selected by the received individual information, and collates whether or not the rental permission key stored in the storage unit 71 matches the received rental permission key. If they match, the individual information of the rental target vehicle and a separation permission request are transmitted to the vehicle management device 204 in order to permit the rental of the rental target vehicle.

The vehicle management device 204 notifies the control unit 7 of the rental vehicle of unlock permission when the vehicle to be rented is not connected to the following vehicle (when the vehicle to be rented is the last vehicle). If the battery 8 is being charged, the control unit 7 of the vehicle to be rented stops charging and unlocks the lock unit 13 . This enables the user to use the rental vehicle. Also, by releasing the lock after stopping charging, electrical safety can be improved. The vehicle management device 204 notifies the management server 210 that the vehicle to be rented has been rented to the user, and the management server 210 updates the database 210 a with the usage information of the vehicle 1 .

When a following vehicle is connected to the rental target vehicle, the vehicle management device 204 notifies the control unit 7 of the following vehicle of an unlock command. The control unit 7 of the following vehicle unlocks the lock unit 13 to separate the following vehicle from the rental vehicle.
