DRAWINGS IN DETAIL

[0034] FIGS. 1A and 1B are side and top views of the preferred embodiment of the invention wherein the assist system is secured to the vehicle via a towing slide mount.

[0035] Referring to FIG. 1A, vehicle 10A has a slide mount 14A secured thereto. Platform 11A is secured into slide mount and presents a foundation for the mounting of motor/generator 12A. Electrical energy from motor/generator 12A is fed through electrical cable 15A which is connected to receptacle 16A of the electric vehicle 10A.

[0036] Receptacle 16A is the traditional connector used to recharge the rechargeable battery (not shown) within vehicle 10A. Unlike the illustration, in the preferred embodiment, receptacle 16A is positioned at the rear of vehicle 10A permitting easier connection with electrical cable 15A.

[0037] Activation and deactivation of motor/generator 12A is preferably done via radio transmitter 17A which is illustrated exterior to vehicle 10A, but, in the ideal embodiment, the operator of vehicle 10A activates from within vehicle 10A, to activate motor/generator 12A when the operator deems that the rechargeable battery needs to be boosted.

[0038] Alternatively, sensor 17B monitors the charge within the rechargeable battery and activates/deactivates motor/generator 12A when needed.

[0039] The embodiment, with the electrical connection within vehicle 10A, is illustrated in FIG. 1B. Again, platform 11B is secured to vehicle 106 on which is mounted motor/generator 12A. In this embodiment, electrical cable 15B is passed into trunk 17 to connect with receptacle 16B. Receptacle 16B is optionally created during manufacture of the electric vehicle 10B or is installed as an after-market item.

[0040] The embodiment of FIG. 1B provides more protection for the connection between electrical cable 15B and receptacle 16B.

[0041] Mounting, and dismounting the assist apparatus to the vehicle is ideally done as a two-step process. In mounting, first the platform is secured to the vehicle and then the motor/generator is secured to the platform. Dismounting is done in the reverse. This two-step process is easier due the component's weight.

[0042] FIG. 2 is side view in which the assist system is being towed as a trailer.

[0043] In this embodiment of the invention, vehicle 20 is equipped with a tow bracket 25 which is secured to trailer 24. Motor/generator 23 is carried by trailer 24. Power from the motor/generator 23 is communicated to vehicle 20 and its electrical receptacle 21 via electrical cable 22.

[0044] FIG. 3 illustrates the internal combustion engine of the present invention.

[0045] In the preferred embodiment, motor 30 is a typical internal combustion engine with its exhaust being muffled for noise concerns. Drive shaft 31 from motor 30 drives generator 32 and the electricity therefrom is communicated to the vehicle (not shown) via electrical cable 37.

[0046] Motor 30 is powered by hydrocarbon s such as gasoline and diesel in liquid form. Canister 35 is used to contain hydrocarbons in the gaseous state such as propane and natural gas. Canister 35 is securable to inlet 38 as indicated by arrows 36.

[0047] FIG. 4 illustrates the preferred embodiment of the U-shaped secondary bumper protection of the assist system in which the secondary bumper contacts the bumper on the vehicle.

[0048] Bumper 40 is generally U shaped with end of the legs 42 proximate to the vehicle's bumper 43. In this embodiment, legs 42 do not contact bumper 43 except during impact. In other embodiments, legs 42 are held firmly against bumper 43.

[0049] FIGS. 5A and 5B illustrate two embodiments which are meant to reduce damage due to impact of the secondary bumper.

[0050] Referring to FIG. 5A, a top view and side view of the preferred bumper used to protect the motor/generator, leg 51A (only one shown in this illustration) are hollow and contain a spring 52 which extends from leg 51A so that on impact with the bumper, leg 51A is forced (arrow 54A) toward the electric vehicle's bumper 50A, allowing spring 52 to absorb the impacts force to minimize damage to bumper protecting the motor generator.

[0051] In FIG. 5B, a collapsible canister 53A is secured to leg 51A. When the leg 51A and canister 53A, are pressed against the vehicle's bumper 50B, collapsible canister “crumbles” 53B as shown by arrow 54B. This crumbling absorbs the impact force to minimize damage.

[0052] FIG. 6 illustrates an embodiment of the invention in which the charging engine is mounted on the roof of the vehicle.

[0053] In this embodiment, platform and charging engine 61 are mounted on the roof of vehicle 60. Power from charging engine 61 is communicated to the battery (not shown) within the vehicle 60 via electrical cable 62.

[0054] It is clear that the present invention provides for an improvement for electric vehicles in order to make these vehicles more acceptable to the general public.
