Description

ELECTRONIC EQUIPMENT CHARGING DEVICE FOR A TWO-WHEELED

VEHICLE

FIELD OF INVENTION

[0001] The present subject matter relates generally to an electronic equipment charging device (EECD) for a saddle type vehicle and more particularly to an installation mechanism of such a device on a body panel of said two-wheeled vehicle.

BACKGROUND OF INVENTION

[0002] Generally, a battery assembly plays a very critical role for the functioning of a vehicle. The battery assembly supplies the required electrical energy to the vehicle for its operation. The vehicle requires an electric supply from the battery for various operations such as providing electrical power to the starter system, display on instrument cluster and powering the light and the sounds system. Moreover, in an electric vehicle the whole power supply for the vehicle operation is done through the battery operation. Thus, battery for a vehicle forms one of the most important elements and many a times the rider may be stranded due to fault in the battery, or an accident can take place if the warning systems working on the electric supply of the battery stops working.

[0003] In addition to it, the vehicle is provided with electronic equipment charging device (EECD) which is connected to the battery. The EECD is provided to help the rider to charge a device by connecting it to the EECD while he/she is riding. Hence, the EECD is provided for the riderDs convenience to make the ride better and smoother. Thus, the EECD should also be provided in such a manner which causes least discomfort to the rider and is easily accommodated in the vehicle as well. However, it is the mounting and location of the EECD that plays an important part. The EECD comprises of various wiring, switches and circuits, hence needs to be placed in a safe and stable location such that it does not gets entangled or breaks down. In furtherance to it, it should be placed in an ideal location which is easily accessible by the rider. However, in a known state of art that is not the case, as the EECD is placed and mounted in locations where the number of failure modes and probability of breakdown increases. Moreover, it is not easy for the rider to easily access it, be it in a riding state or idle state.

[0004] Thus the present system provides stable and easily accessible mounting location for the EECD. In addition to it, the present subject matter provides a simple and secure mounting for the EECD which is tamper proof & does not create a hindrance for the vehicle or any other part mounted on it.

DETAILED DESCRIPTION [00013] Typically, a two-wheeled vehicle comprises of a frame assembly extending rearwardly from a head tube. The frame assembly acts as a skeleton and a structural member for the vehicle that supports the vehicle loads. A front wheel is connected to a front portion of the frame assembly through one or more front suspension(s). The frame assembly extends towards a rear portion of the vehicle. A rear wheel is connected to a frame assembly through one or more rear suspension(s). The frame assembly comprises of an engine assembly coupled to it. The engine assembly is functionally connected to the rear wheel, which provides forward motion to the vehicle. A muffler assembly is provided at a lateral side of the vehicle mounted to the frame assembly or the vehicle through a mounting bracket. Typically, plurality of panels is mounted to the frame assembly of the vehicle that covers various vehicle parts mounted thereon.

[00014] Moreover, when it comes to the electrical supply requirement of a vehicle, a battery is added to fulfill it. The battery caters to the need of various electrical operations such as providing electrical power to the starter system, display on instrument cluster and powering the light and the sounds system, and in an electric vehicle the whole power supply for the vehicle operation is done through the battery operation. In addition to it, an EECD is added to the vehicle to fulfill the changing needs of the rider. The EECD is provided to establish a secure electrical supply for charging a device connected to it. The EECD derives its power from the battery and helps in charging of the device connected to it.

[00015] In one of the known arts the EECD is placed in an instrument cluster or the vehicle headlamp housing. However, the instrument cluster or the vehicle headlamp housing is mounted on the vehicular front and accommodates speedometer which receives electronic signal inputs from various parts of the vehicle. This makes the speedometer area clumsy. Further, the speedometer is installed in a portion of headlamp housing. During normal course of usage of the vehicle, when the headlamp is in D OND state, a large amount of heat is generated which may damage the electronic equipment charging device and render it unusable. Hence, installation of an electronic equipment charging device in the region surrounding the headlamp housing becomes difficult owing to clustered signal cables in that region and generation of a large amount of heat. In addition to it, when the EECD is provided at such a location, it becomes hard for the rider to access it, since it is placed at a substantial distance from the rider. Hence, it is desired to locate and install the electronic equipment charging device to a location where installation is easier and the charging device can be installed without fouling with other parts or components of the vehicle.

[00016] Hence, it is an objective of the present subject matter to provide a stable and safe mounting for the EECD, such that neither does it interferes with any other part, nor is there any possibility of damage to it or any other part as such. In addition to it, the EECD is disposed at such a location which is comfortable and easy for the rider to access.

[00017] In an embodiment in accordance with the present subject matter, a two- wheeled vehicle is employed with a frame assembly which functions as a skeleton for the whole vehicle. All the systems and assemblies for the vehicle such as handlebar assembly, headlamp unit, front fork, engine assembly etc. are mounted over the frame assembly. The frame assembly comprises of at least one head tube disposed at a front portion of the vehicle. Furthermore, the frame assembly comprises of a front sub frame assembly connected to the head tube and extending in a rearward direction. In addition to it, a rear sub frame is provided connected to the rear end of the front sub frame assembly and extending in a rearward direction along the vehicle length.

[00018] In an embodiment, a storage unit is mounted on the frame assembly in a front portion of the vehicle. In furtherance to it, the storage unit is covered by a cover storage unit. The vehicle is also provided with a battery to meet its electrical supply needs. Moreover, the vehicle comprises of an electronic equipment charging device (EECD) which the rider can use to connect his/her electronic device and charge it. The EECD is also connected to the battery and derives its electric power from it.

[00019] In an embodiment, the EECD is located on the cover storage unit of the vehicle. As per an embodiment of the present subject matter, an EECD aperture is provided on the surface of the cover storage unit near the rider end, wherein the EECD is inserted through it. According to an aspect of the present subject matter, the EECD aperture is provide in a close proximity to the rider for an easy access of the EECD. A plurality of mounting arrangements is provided on the inner surface of the cover fuel tank through which the EECD is mounted on it. According to an aspect of the present subject matter, the protruding portion of the EECD is in the same line as that of the outer surface of the cover storage unit. Thus, the EECD is in the same line as that of outer surface of the cover storage unit and nothing protrudes out. The EECD body is disposed below the cover storage unit and thus is hidden. In another embodiment, the power train for the vehicle can be an electric motor or a hybrid one. Also, a storage unit may be disposed in front of the rider which may be used for fuel storage like gasoline, LPG, fuel cell, battery, utility items etc.

[00020] Thus, the present subject matter provides a safe and secure mounting for the EECD such that the possibility of damage and interference with other parts is reduced. In addition to it, an ample amount of space is provided for the EECD, and the EECD is located at such a place which is easily accessible by the rider.
