Electric mobile body

The present invention relates to an electric movable body using a motor as a driving source. In addition, among the "electric mobile bodies" described herein, of course, electric vehicles such as electric bicycles, motorcycles, motor tricycles, and motor vehicles are included.

Conventionally, a moving body called a motor vehicle and/or a motorcycle has generally used an engine that uses gasoline (gasoline) or diesel as a fuel to obtain a driving force as a driving source. However, the development of electric movable bodies and electric vehicles that use a motor that uses electric power as a driving force as a driving source has been attracting attention as a countermeasure against environmental protection.

The electric vehicle is provided with a battery belonging to a secondary battery in the same manner as a personal computer or the like, and electric power is supplied from the battery to the motor drive unit, the motor, the control unit, and the like. A relatively thick power supply line as a power supply path for supplying electric power for driving the motor is connected between the battery and the motor drive unit and between the motor drive unit and the motor. In the power supply line, generally, an electric wire such as a wire harness and/or a cable harness is used.

In Patent Document 1, an example of an electric vehicle using a wire harness from a power supply path for supplying electric power for driving a motor to a motor drive unit and/or a motor as described above can be seen. The wire harness of the electric motorcycle according to Patent Document 1 has a structure in which a motor drive device provided directly under the driver's seat inputs electric power from a battery provided near the front wheel to output a drive to a motor provided in the vicinity of the rear wheel axle. In electric two-wheeled vehicles, the battery and the motor drive unit and the motor drive unit and the motor are respectively connected by a high voltage harness.

Patent Document 1: Japanese Laid-Open Patent Publication No. 2006-182315.

However, since a so-called electric wire such as a wire harness is used, there is a concern that the number of components is increased. Further, since it is necessary to apply relatively large electric power in order to drive the motor, it is necessary to use a wire bundle having a relatively large wire diameter. Therefore, when the harness structure of the electric two-wheeled vehicle described in Patent Document 1 is connected between the battery and the motor driving device and between the motor driving device and the motor by a high voltage harness, respectively, the electric wire bundle itself becomes heavy and the electric vehicle is made. The weight of the increase is doubtful.

In addition, wire bundles with a relatively large wire diameter may also be difficult to handle in a vehicle. Therefore, it is highly probable that the manufacturing time of the electric vehicle is time-consuming, or the wiring man-hour is increased, resulting in a decrease in manufacturing efficiency.

Furthermore, the wiring harness has a problem that power loss occurs as the wiring distance becomes longer. Therefore, since the driving efficiency of the motor is lowered, in order to improve the driving efficiency, it is preferable to design the distance between the motor driving portion and the motor to be as small as possible.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a power supply path that can suppress power transmission and reception between a motor, a battery, and a motor drive unit, and can reduce the number of components and components.

According to this configuration, since the power terminals are electrically connected to each other between at least two of the motor, the battery, and the motor driving portion by direct mounting or bus bars, there is no need for the direct mounting portion or the bus bar connecting portion of the power terminals. Use a wire harness. Therefore, power loss in the power supply path is suppressed, and the number of components and the weight of the member are reduced.

In addition, the "direct mounting" of the electric power supply path described herein means that the electric power supply path between the motor, the battery, and the motor drive unit does not use a so-called electric wire such as a wire harness, but is directly electrically charged. Connector. Specifically, for example, the direct connection of the power supply path can be realized by directly connecting the terminal to the terminal or by connecting the terminals to each other using a joint, but it is also possible to use other connection methods without using the electric wire.

Further, the electric movable body having the above configuration includes a control unit for controlling the motor drive unit, and the motor drive unit and the control unit are integrally formed.

According to this configuration, since the motor drive unit and the control unit are integrally formed, it is not necessary to use the electric wire bundle between the motor drive unit and the control unit. Therefore, the power loss in the power supply path is further suppressed, and the number of components and the weight of the member are reduced.

Further, in the electric movable body having the above configuration, the motor and the motor drive unit are integrally formed.

According to this configuration, since the motor and the motor drive unit are integrally formed, it is not necessary to use, for example, a terminal or a bus bar for direct mounting between the motor and the motor drive unit. Then, by directly mounting or electrically connecting the motor and the electric power supply path between the motor drive unit and the battery, it is not necessary to use the electric wire bundle for all the electric power supply paths between the motor, the battery, and the motor drive unit.

Further, the electric movable body having the above configuration includes a signal terminal provided in each of the motor, the battery, and the motor drive unit for transmitting and receiving a control signal, and the signal terminals are directly mounted or connected to each other. The bus bar is electrically connected between at least two of the motor, the battery, and the motor drive unit.

According to this configuration, since the signal path is directly mounted or electrically connected between the motor, the battery, and the motor drive unit, the transmission loss of the control signal is suppressed in the signal path in addition to the advantages of the power supply path. And reduce the number of components and the weight of the components.

Further, the electric movable body having the above configuration includes a frame for supporting each of the motor, the battery, and the motor driving unit, and a motor for accommodating the frame, the battery, and the motor drive. The accommodating department of each department.

According to this configuration, since the electric movable body includes the accommodating portion for accommodating each of the motor, the battery, and the motor drive unit, the components can be disposed in a space-efficient manner. Therefore, it is easy to directly mount or electrically connect the power supply paths of the constituent elements by bus.

Further, in the electric movable body having the above configuration, the frame is formed in a tubular shape, and each of the accommodating portions for accommodating each of the motor, the battery, and the motor driving portion is formed inside the frame.

According to this configuration, each of the motor, the battery, and the motor drive unit is housed inside the frame. Therefore, it is easy to form a protection to prevent the motor, the battery, and the motor drive unit from being adversely affected by water, dust, or the like.
