[0014] Figure 9 Shows a charging inlet assembly according to an embodiment of the present subject matter. Detailed Description

[0015] An electric vehicle is provided with a power source such as a battery to supply power to a prime mover such as an electric motor to run the vehicle. The battery in an electric vehicle requires a charging system for charging purposes, and the charging system can be an on-vehicle charging system or an off-vehicle charging system. When the battery discharges after consumption and needs to be recharged, an on-vehicle charging system or an off-vehicle charging system can be used. The battery can be charged at a charging station or at home with a power source. However, most charging stations have problems associated with slow charging processes, non-standardized charging inlets, the size and weight of the charging inlets, and customizing charging inlets for specific models of electric vehicles.

[0016] In addition, compared to three-wheeled or four-wheeled vehicles, two-wheeled vehicles are more compact in size, and it means that more than two riders face the challenge of removing and reinstalling the battery required for charging. Therefore, this requires an on-vehicle charging system that can be accommodated inside the body of a two-wheeled vehicle together with the battery.

[0017] The on-vehicle charging system in a two-wheeled vehicle requires a charging port to charge the on-vehicle battery. The on-vehicle charging system can use alternating current or direct current, or a combination of both alternating current and direct current. The charging inlet provided in the vehicle to facilitate the battery charging process is also referred to as a charging inlet. A charging gun is engaged with the charging inlet to initiate the charging process. To protect the charging inlet from any environmental factors such as dust or water, it is necessary to cover the charging inlet. It is also important that the charging inlet should be protected against any unauthorized access to eliminate the possibility of damaging the charging inlet.

[0018] In three-wheeled or four-wheeled vehicles that accommodate three or more commuters, state-of-the-art technology provides a hinged or rubber cover that closes the charging inlet, as well as a separate body panel that is rotatably mounted therewith to cover the charging inlet. However, in the case of two-wheeled vehicles, the charging inlet only has a snap-on plastic cover, which is prone to opening and damage during unauthorized access or over time with use.

[0019] Furthermore, during the process of plugging and unplugging the charging inlet, the charging inlet remains exposed to dust and water, so it is necessary to provide a prevention mechanism that can prevent dust and water from entering even during the charging process. Additionally, at the same time, the prevention mechanism should be repairable because frequent charging processes involve plugging and unplugging processes, which ultimately lead to wear and tear of the devices used as the prevention mechanism. Therefore, an improved solution is needed to overcome all of the above problems and other problems of the prior art.

[0020] The present subject matter provides a charging inlet assembly in a two-wheeled vehicle to solve the above problems. The charging inlet assembly according to the present invention is capable of receiving a power source connector leading to an external power source such as a power station. The charging inlet assembly includes one or more structural members that are removably mounted on each other such that if one of the structural members is damaged, the charging inlet does not need to be removed from the vehicle, and the damaged structural member can be removed and replaced with a new part.

[0021] Furthermore, another embodiment of the present subject matter provides a charging inlet assembly having a closable cover member that is rotatably mounted on one of the structural members by a spring-loaded hinge. The closable cover member is locked by a mechanical lock or an electronic lock.

[0022] Another embodiment of the present subject matter provides one or more structural members that are removably arranged in a layered manner. The structural members are an upper member and a lower member, wherein the upper member is provided with a pair of protrusions for locking with the rear inlet panel of the vehicle.

[0023] Yet another embodiment of the present subject matter provides an ingress prevention device that is accommodated between the upper member and the lower member to prevent water from invading the charging inlet assembly. The ingress prevention device is accommodated in a groove formed peripherally on the lower surface of the upper member.

[0024] Another embodiment of the present subject matter provides a cover member that is rotatably mounted on the upper member by a hinge, and the cover member can be locked by a mechanical or electronic device. The cover member is locked by a mechanical latch. The locking device for the cover member can be manually operated with a physical key or electronically operated by an electronic key such as a key fob.

[0025] Another embodiment of the present subject matter provides a switch unit disposed on an upper region of a charging inlet assembly. The switch unit continuously senses an open or closed state of a lid member. When the lid member is in a closed state, the switch unit gives an indication to a driver by using an indicator light of an LED lamp or an audio indication such as a buzzer.
