DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0027] One embodiment of the present invention of a light electric moped [100] as shown in Figure 1 is comprised of a space frame monocoque chassis [1] constructed out of formed sheet metal and held in position through any of the preferred metal joining process to make it light weight , the said monocoque chassis [1] accommodates front fork assembly [2], front wheel assembly [3], headlight assembly[8], front storage compartment [17] at the front section, a seat [10], electric powertrain [12] at the middle section, a rear wheel assembly[13], wheel integrated gearbox [16], and saree guard assembly[18] at the rear section.
[0028] The space frame monocoque chassis [1] as illustrated in Figure 2 houses two helmets [36], a removable battery [9] and a fixed battery [33], the electronic control boxes [32] [34] [35], tail light assembly [35] and electric powertrain assembly [12]. The combination of fixed battery [33] & removable battery [9] work in tandem to supply power to the control boxes [32] [34] [36], electric powertrain [12], headlight assembly [8] and acts a burglarproofing for the electric moped [100] when one of the batteries is removed. The removable battery [9] is held at such inclined position (angle) within the chassis [100] to enable easy removal of the said battery [9].
[0029] The headlight assembly [8] is held in position between fork assembly [2] and chassis [1] pivot mount as illustrated in the present embodiment. The front wheel assembly [3], the front mud guard assembly [19] are connected to headlight assembly [8] through the front fork assembly [2] and pivoted in position through chassis [1] pivot mount. The Rear wheel assembly [13] , the saree guard [18] and the mudguard [19] are mounted to the rear end of the electric powertrain [12] at one end and shock absorber [16] at the other end, the said shock absorber [16] is connected to the rear end of the space frame monocoque chassis [1]. Similarly, the stand assembly [42] is mounted to the bottom section of the chassis [1].
[0030] The said chassis [1] constructions as shown in Figure 3 enables it to achieve protection of critical functional components against mechanical damage, Ingress and theft.
[0031] The Figure 4 illustrates an embodiment of wheel integrated gearbox [13] connected to the rear end of the electric powertrain [12] at one end and to the side arm [26] at the other end. The said gearbox [13] integrated to the wheel receives the mechanical power from the electric powertrain [12] and transmits the same to the wheel.
[0032] The side arm [26], stand assembly [42] and foot rest [23] is connected to the chassis [1] as illustrated in the Figure 5.
[0033] The Figure 6 illustrates two possible helmet [36] storage location inside the light electric moped [100].
[0034] In another embodiment as illustrated in Figure 7 the fork plate [2a] is interlocked between the Head light [8a] and the handle bar [8b] by following an assembly sequence to ensure burglarproofing of the headlight assembly [8].
[0035] The vehicle control architecture as illustrated in Figure 8 comprising of control boards such as Head Unit Control Board [8d], CAN GPA board 2 [34a], Motor control unit [12a], vehicle control unit [32a] & CAN GPA board 1 [35a] are connected in any preferred network topology like distributed network to minimize the number of wire harness and ensure secured communication between the control boards. The batteries [9] and [33] forms the part of said network topology and supplies the required power to all the control boards. In such cases where in either one of the batteries [9], [33] is removed or disconnected, the vehicle control unit [32a] triggers a communication signal to deactivate all the control boards in the said electric moped [100] to ensure burglar proofing.
