Description

A MONO TUBE VEHICLE

TECHNICAL FIELD

[0001] The present subject matter described herein generally relates to a saddle type wheeled vehicle, and particularly but not exclusively relates to a mono tube backbone frame structure of a saddle type wheeled vehicle.

BACKGROUND

[0002] Typically, a mono-tube type frame assembly of a two-wheeler, for example, a moped, includes a tubular single down portion with a lower cradle frame often referred to as a backbone frame structure. Particularly, the mono-tube type frame assembly includes a head portion, a main portion, a down portion, and a rear portion. The main portion extends rearwardly downward from the head portion. The down portion extends rearward, along a longitudinal axis of the vehicle, from a rear portion of the main portion. The rear portion extends inclinedly rearward from the down portion towards rear of the vehicle.

[0003] Moreover, in such mono-tube two-wheeled vehicle, a step-through space is provided. The step-though space provided may be used for carrying loads or for the rider to rest feet. Generally, a front wheel and a rear wheel are mounted to the frame structure of the vehicle. The front wheel is rotatably connected to the frame structure through one or more front suspension(s) and a rear wheel is connected to the frame structure through one or more rear suspension(s). Generally, such vehicles are provided with an internal combustion engine functionally connected to the rear wheel, which provides the forward motion to the vehicle. Typically, plurality of panels are mounted to the frame structure of the vehicle that cover various vehicle components. The vehicle components include electrical and electronic components including an electric starter system. Also, some of the vehicles have an anti-lock braking system, a synchronous braking system, or a vehicle control unit. The electrical and electronic components are powered by an on-board auxiliary power source.

[0004] Such mono-tube vehicles are usually low-powered two-wheelers which are often high-economy type vehicles, usually having engine displacement not more than 50 cc (3.1 cu in) or motor rating not more than 1.5 kilowatts (2.04 PS; 2.01 bhp). Such vehicles, usually does not require clutching or gear shifting after the drive system is engaged and usually weigh less when compared with two wheelers having dual-tube type frame assembly. Such vehicles are designed keeping in mind the convenience and requirements of a working class and women, while keeping the technology as economical as possible.

DETAILED DESCRIPTION

[00015] Generally, the two-wheeled vehicles with internal combustion engines provide desired torque and power, depending on demand from user. Moreover, such vehicles with step-through type frame structure are widely popular for their compact layout and load carrying space. Generally, gasoline is used as fuel in such vehicles. However, such vehicles are known for emissions due to the combustion process taking place in the internal combustion (IC) engine.

[00016] However, with time, vehicles are provided with an electrical motor that is capable of operating in conjunction with the IC engine. Such electric motor provided is used to provide initial moment to the vehicle, which otherwise have higher fuel consumption and result in higher emission due to reasons like cold start. Thus, the electric motor is used in reducing emissions and improving the economy of the vehicle to some extent. Nevertheless, such vehicles still result in emissions and also require space on the vehicle for accommodating the large sized internal combustion engine. Especially, such a problem is more prominent in compact vehicles such as mono-tube vehicles, having naked appearance.

[00017] With the advent of technology, these vehicles are employed with only the electric motor that is capable of providing sufficient torque at wide range of speeds. Also, such vehicles are more economical, dependable, and require low maintenance. In such vehicles, the electric motor is driven by auxiliary power source, for example a battery. The range (distance) the vehicle can run depends on the capacity of battery being used. A large capacity battery is usually desired, as it is capable of improving the range of the vehicle.

[00018] Conventionally, in order to accommodate the large capacity battery, the vehicle layout is modified whereby the compact layout and the utility space are compromised. For example, some vehicles are provided with batteries below the seat that are inclinedly disposed and such batteries are accessible only in an open condition of the seat assembly. Such modified layout becomes cumbersome for the user to access the batteries for replacement or servicing.

[00019] Moreover, the batteries disposed below the seat are generally away from the longitudinal center of the vehicle because of which the weight distribution is uneven and is biased onto the rear wheel, which is not desired.

[00020] In some other implementations, the batteries are disposed at the step-though space itself eating away the step-through space, compromising on the utility space and adversely affecting the load carrying function of the vehicle.

[00021] Furthermore, some known arts disclose about mono-tube vehicles including the batteries disposed on the swing arm of the vehicle, which requires the swing arm to be larger size when compared with usually implemented size of the swing arm. Such large size swing arm is required in order to support the rear wheel, the batteries, and the electric motor. This in turn increases the overall weight and size of the vehicle. Also, such vehicles offer poor riding dynamics. For example, in certain vehicles, the wheel base is increased for accommodating the batteries on the swing arm, which affects the turning radius and also the maneuverability of the vehicle.

[00022] Moreover, some known arts disclose about vehicles accommodating the batteries at the step-through portion of the mono-tube frame of the vehicle; however, such vehicles have a complex frame layout or complex mounting schemes that affect the compact layout of the vehicle. For example, the frame itself is used for storing batteries on the vehicle. However, this affects the structural integrity of the frame, which is the structural member of the vehicle. Moreover, conventionally multiple railings/tubes are used to accommodate and mount the batteries. This requires multiple welding on the frame to connect the multiple railings. This also necessitates additional welding procedure, and also results in distortions in the frame. In addition, these frames, even though they offer step- through space for loads, are poor by serviceability design since the batteries can be accessed only from the top portion thereby requiring the loads to be removed. This contingency is cumbersome as the user has to remove the loads to access the batteries. Therefore, ease of access becomes a major challenge in such layouts.

[00023] Some known arts disclose about vehicles accommodating motor and battery below the main frame and above the foot rest assembly. In such designs the foot rest assembly is required to be unfolded and disassembled completely in order to access the motor and the battery, making the whole process a lot more cumbersome.

[00024] Further, the amount of load that can be disposed at the step-though space may also be limited due to presence of batteries thereat. Also, because of such placement of the batteries, adequate placement of other necessary electronic components, such as an on board charger and controller becomes a difficult task. Because of inadequate placement of such electronic components, such electronic components are subjected to heating due to poor ventilation thereby requiring forced cooling like use of electric fans that consumes battery power and requires more accommodating space. [00025] Hence, there is a need to create an improved compact layout design of a two wheeled mono tube vehicle with utility space for configuring easy accessibility of electronic components.

[00026] The present subject matter has been devised in view of the above circumstances as well as solving other problems of the known art.

The second bracket 195b includes arresting means, for example a first arresting means 415a and a second arresting means 415b. The first and second arresting means 415a and 415b aid in arresting the position of the third power source 205c, which is supported by the second bracket 195b. The first and second arresting means 415a and 415b together restrict the movement of the third power source 205 c both in lateral and horizontal direction, thereby ensuring that the third power source 205c remains stationary, secured and stable in place even when the vehicle 100 is in motion. The second bracket 195b also includes one or more attachment provision 410. The attachment provision 410 aids in detachable attachment of the second bracket 195b.

[00055] Fig. 7b illustrates a perspective view of one or more first bracket 195a along with the footrest assembly 180 of an exemplary two- wheeled mono-tube vehicle 100, in accordance with an embodiment of present subject matter. The one or more first bracket 195a includes one or more attachment provision, for example 420 and 415c. The one or more first bracket 195a further includes one or more arresting means, for example a third arresting means 425. The third arresting means 425 aids in restricting the movement of the motor 300 both in lateral and horizontal direction, thereby ensuring that the motor 300 remains stationary and in place even when the vehicle 100 is in motion. The one or more attachment provisions 420, 415c aids in detachable attachment of the first bracket 195a from the second bracket 195b, to ensure easy accessibility of the motor 300. The first bracket 195a is attached on one rear end to the foot rest assembly 180. Therefore, the foot rest assembly 180 remains swingably intact with the first bracket 195a when the first bracket 195a is detached from the frame assembly and the second bracket 195b, by means of accessing the attachment provisions 420 and 415c, making the whole serviceability process of the motor easy.

[00056] Fig 8 illustrates a partially exploded side perspective view of an exemplary two- wheeled mono-tube vehicle 100, in accordance with an embodiment of present subject matter. Fig. 8 illustrates the auxiliary storage compartment 205, disposed below the rider seat 160A (shown in Fig. 1), which is supported by the seat mounting bracket 175. The rider seat 160A is present hingedly above the auxiliary storage compartment 205. This enables ease of access to the one or more electronic component, for example a controller 500, for maintenance. The rider seat 160A is secured above the auxiliary storage compartment 185 by a lock assembly (not shown). The auxiliary storage compartment 205 is disposed onto the rear portion 105D and substantially above the down portion 105C. The auxiliary storage compartment 205 includes a first part 500a and a second part 500b. A controller 500 is placed inside the auxiliary storage compartment 205 when both the first part 500a and the second part 500b are sandwiched together by fastening means.

[00057] The controller 500 is used to run the motor 300 as per the road and load demands of the vehicle 100 and also aids in recharging the battery at the regeneration stage. Therefore, the placement of the controller 500 in the present embodiment, is such that the controller 300 is intermediate between the power source(s) (205a, 205b, 205c) and the motor 300. Such layout configuration also aids in avoiding the over and under flow of the current or voltage to the motor 300, therefore ensuring safety of the motor 300.
