Description

The present invention relates generally to charger units. More particularly, but not exclusively, the present invention relates to charger units for vehicles.

Generally, in electric vehicles, one or more batteries are used as a power source to power the traction motor and thereby drive the vehicle. During vehicle towing, the battery discharges and needs to be replaced or recharged. Replacing the battery is not a preferred option for the vehicle user due to the heavy weight of the battery. Therefore, to make it easier for the customer, manufacturers are offering batteries of the rechargeable type so that the vehicle user can easily recharge the battery whenever needed. can be done. To charge the battery, a power supply is required from a charging station or domestic power supply. A charger unit is required to connect the battery and power supply and allow charge to be transferred from the charging station/mains supply to the battery. Charger units are mainly of two types: off-board chargers and on-board chargers. Off-board chargers are required to be carried by the user and require storage space within the vehicle. Off-board chargers are generally large in size and not convenient to carry. Therefore, on-board chargers are preferred.

However, in a compact layout, especially in a two-wheeled vehicle, packaging the charger unit and mounting it in a convenient location is a challenge. Especially in electric and hybrid vehicles, additional electrical parts are involved, thus making packaging of the vehicle even more difficult. In step-through electric vehicles, style panels cover all vehicle components, thereby further limiting the available space for packaging.

The size of the charger unit is proportional to the battery size, i.e. the larger the capacity of the vehicle, the larger the battery required, which in turn requires the larger charger unit, thereby increasing space and assembly time requirements. has further complicated the packaging challenge.

Generally, in a two-wheeled electric vehicle, the battery is placed in the rear area of the vehicle and the charging unit is placed in either the front, middle and rear areas of the vehicle. In scenarios where the charger unit is placed at the front of the vehicle, the long cable length connecting the battery and charger unit causes some power loss, also called wiring harness loss. In other cases, where the charger unit is placed in a central area of the vehicle, it is difficult to access and service the charger unit. Utility space is compromised in the case where the charger unit is arranged in the rear area of the vehicle.

In addition, the appearance of the vehicle is also an important factor for customers considering the purchase of a vehicle. Therefore, there is a need for efficient compact packaging of vehicles without compromising the appearance of the vehicle.

Therefore, what is needed is an improved layout and configuration of a charger unit in a compact vehicle that overcomes all the above problems and others of the known art. It satisfies the requirements related to the stability of the charger, the minimum connection length between the charger and the battery, and the accessibility of the charging slot by the user, and can be assembled within the existing layout of the two-wheeled motor vehicle, assembled and There is a need for improved location and mounting arrangements for charger units with minimizing the time for maintenance work.

To accomplish one or more of the above-stated and other related objectives, the present invention provides a charger powered by a battery as a power source and located in a safe and secure location to provide optimum performance. A vehicle having a unit is provided. Also, the mounting location and mounting configuration of the charger unit facilitates easy accessibility, fewer parts assembly, and serviceability. The charger unit provided in the present invention is constructed with fewer parts, which increases durability, provides efficient cooling of the charger unit, and results in a lighter weight.

SUMMARY OF THE INVENTION The present invention provides a two-wheeled vehicle including a frame and a charger unit. The frame includes a front portion and a rear portion. A charger is disposed in the rear portion of the frame. The charger unit is located in an area in which a first imaginary line extending downward and forward in the longitudinal direction of the vehicle from the bottom surface of the charger unit is located forward of the front axle point of the front wheel when viewed from the side of the vehicle. , is placed in a tilted position so that it intersects a second imaginary line passing through the steering axis. The charger unit is oriented in a tilted position when viewed from the side view of the vehicle to ensure that the utility space in the utility box and the clearance of the rear wheels are not compromised to interfere with the functioning of the two-wheeled vehicle. If the charger is placed in a horizontal orientation consistent with the longitudinal direction of the vehicle, the charger unit will occupy some of the utility space of the storage box, reducing or compromising the size of the utility box. If the charger is placed in a vertical orientation perpendicular to the longitudinal direction of the vehicle, the charger unit will interfere with the available clearance for the rear wheels, which is undesirable. Therefore, by configuring the charger unit in an inclined position between the horizontal and vertical planes, the packaging and mounting of the charger unit can be done in a compact space and with a compact layout of the parts in that area. and without compromising the arrangement.

In an embodiment of the invention, the rear portion of the frame includes a left rear frame and a right rear frame, and the charger unit is disposed between the left rear frame and the right rear frame. In another embodiment of the invention, the battery charger unit is disposed between the pair of rear shock absorbers below the seat assembly. The battery charger unit is laterally offset from the center of the two-wheeled vehicle.

Another embodiment of the present invention is to provide a charging input port on the rear side of a charger unit located in the rear portion of the vehicle so that it can be accessed for charging. To ensure accessibility of the charging input port, an opening is provided in the rear portion of the vehicle's rear panel positioned below the rear seat handles and above the rear tail lamp assembly of the two-wheeled vehicle. This mounting configuration of the charger unit eliminates unwanted bending of the charger input port cable, thus facilitating direct connection between the charging input port and the charging gun/charging point. This reduces wear and tear from use on the cables and input ports, increasing their lifespan.

According to another embodiment of the invention, mounting the charger unit is accomplished using a minimal number of parts. The charger unit is mounted by a single mounting portion at the front portion of the rear crossbridge and multiple mounting portions are provided within the rear portion of the rear crossbridge member, the rear crossbridge being the left rear portion of the two wheel vehicle. It is placed between the frame member and the right rear frame member. This mounting configuration allows efficient mounting of the charger unit on the vehicle, whereby the mounting scheme uses a minimal number of mounting means. If the charger unit is placed in a horizontal orientation rather than an oblique orientation, four or more mounting means are required to secure the charger unit in place. The mounting scheme and layout according to this configuration therefore reduces the number of mounting means required to support the charger unit.

Another embodiment of the present invention is to provide a fan for forced cooling of the charger unit mounted on the upper portion of the rear fender. The axis of the cooling fan is normal to the bottom surface of the charger unit. The above arrangement directs fresh air inside the charger unit for cooling. The charger unit is provided with a plurality of cutouts near the cooling fan so that hot air can escape from the charger unit to keep the charger unit cool. However, in alternate embodiments, the fan may be mounted anywhere else within the rear portion of the two-wheeled vehicle to allow air to reach and exit the charger unit for cooling purposes. can also

According to another embodiment of the present subject matter, the fan is placed in an inclined position with the charger unit such that the hot air exiting the charger unit spreads into the available open space around the charger unit. .

According to another embodiment of the invention, multiple cooling fins are provided on the charger. The cooling fins are arranged together to form a trapezoidal shape in side view so that the charger unit fits inside the casing. The cooling fins thus arranged provide sufficient cooling for the charger with improved packaging within the charger unit.

According to another embodiment of the invention, the charger unit input extension includes a first protruding lug surface and a second protruding lug surface. The casing includes a plurality of cutouts for airflow to ensure cooling of the charger placed inside the casing. A plurality of cutouts built into the casing also act as an arrestor to limit rotation of the charger unit.

According to another embodiment of the invention, the first slot of the casing includes first and second casing faces that are perpendicular to each other. The first casing surface abuts the first projecting lug surface and the second casing surface abuts the second projecting lug surface of the charger input extension to constrain the freedom of the charger unit. This ensures that the charger unit does not move inside the casing, thus restraining its movement.

According to another embodiment of the invention, a charger unit having a casing includes an upper portion and a lower portion attached to each other. The lower portion has a bottom surface and a plurality of side surfaces extending upwardly from the bottom surface of the casing. The lower part opens from one side of the casing. The upper portion slopes upwardly from the front of the lower portion toward the rear of the casing to create a space inside the casing to accommodate the charger. The casing includes a plurality of cutouts provided on the upper portion and the lower portion. These cutouts made in the casing reduce the weight of the casing, thus resulting in a lighter charger unit.

According to another embodiment of the invention, the first slot for the input extension and the second slot for the output extension are provided at the junction of the bottom surface and the side surfaces of the casing.

According to another embodiment of the invention, the casing is provided with attachment points on the upper portion of the obliquely arranged upper portion, the two-point attachment extending upwardly from the surface of the lower portion. Disposed on the rear end of the lower portion.

According to another embodiment of the invention, the charger unit comprises front mounting means provided on the front portion of the rear cross-bridge member at one end and on the distal end of the rear cross-bridge member. and a plurality of second attachment means provided.
