Description:FIELD OF THE INVENTION
[0001] The present disclosure is generally related to a saddle-type vehicle in which a battery and an electric motor are compactly and efficiently mounted on the vehicle frame, hence avoiding a vehicle’s bottom part from hitting or striking the ground while riding the saddle type vehicle.
BACKGROUND OF THE INVENTION
[0002] There are many numbers of electric vehicles present in the market that mount a battery and an electric motor on a frame of the vehicle. Some patent discloses a saddle-type electric vehicle in which the electric motor is disposed below a main frame of a vehicle body. Further, the vehicle body is supported by the main frame, and a battery as a heavy object is disposed below the electric motor.
[0003] Another patent discloses the saddle-type electric vehicles that include a drive motor unit fixedly supported under a main frame extending rearward from a head pipe and a drive battery disposed under the drive motor unit. The drive motor unit has a motor body mounted in its front portion and a transmission (driven element) extending toward the rear of the motor body. The rear end of the transmission is located immediately in front of a pivot of a swing arm.
[0004] Conventionally, there exist various saddle type vehicles that equipped with an electric motor with respect to a pivot axis of a swing arm and a motor axis located between a battery compartment and the pivot axis of the swing arm. But these vehicles are not used at least two mounting elements [at least six LH (left-hand) points and at least two RH (right-hand) points] for mounting the electric motor below the swing arm.
[0005] For example, US20150269520A1 discloses a saddle-type electric vehicle is provided with a drive battery and an effectively placed motor unit. The drive battery is mounted directly under a main frame section of a vehicle frame, and the motor unit is fixedly supported to the vehicle frame. The motor unit includes a motor body disposed below a pivot connection of a swing arm, and at least a part of the motor body is disposed rearwardly of the pivot connection.
[0006] But the above-disclosed patent has some disadvantages. The above saddle-type electric vehicle discloses a drive battery and a motor unit. The motor unit includes a motor body that is disposed below a pivot connection of a swing arm. But the above patent doesn’t disclose the at least two mounting elements for effectively mounting the electric motor for securing a larger space to accommodate a larger battery.
[0007] In order to overcome the aforementioned drawbacks, there is a need to provide a saddle type vehicle that is an enhancement to the conventional vehicle. This invention is capable of mounting the electric motor with respect to the pivot axis of the swing arm so that a rear wheel weight and an electric motor weight are balanced in a seesaw manner. This arrangement increases the stability and durability of the electric motor placed below a pivot connection of the swing arm.

[0009] Another object of the present invention is to provide a saddle type vehicle equipped with an electric motor below a pivot connection of a swing arm.
[0010] Another object of the present invention is to provide a saddle type vehicle that helps in balancing a rear wheel weight and an electric motor weight in a seesaw manner by mounting the electric motor with respect to a pivot axis of the swing arm.
[0011] Another object of the present invention is to provide a saddle type vehicle that is capable of ensuring a large battery storage space by placing the electric motor in a right place.
[0012] Another object of the present invention is to provide a saddle type vehicle that is easy to design, and cost-effective.
