Abstract

An electric vehicle system (EVDPU system) with a detachable power supply has at least two vehicles, one of which is an electric vehicle with a detachable power supply (battery), and normally at least one of the vehicles has an antenna system that can be easily retracted from the tram/trolley power supply network, which supplies driving power to all vehicles via at least one antenna connector and an inter-vehicle power transfer system (unless the electric vehicle is towed using organic/non-electric fuel vehicles). Electric vehicles have all the necessary equipment to introduce dc/ac and recharge/discharge including inverters/converters, regenerators, electronic controllers and signalling devices, such electrical devices including speed/brake control, energy regeneration/storage devices, automatic gear shifting and disconnecting/connecting devices. The energy regeneration/storage device includes a detachable solar panel.

Description

Electric vehicles with detachable power supply units

technical field

The present invention relates to an EVDPU, namely an electric vehicle with a detachable power supply unit.

Background technique

Electric vehicles run either on batteries or on electric power obtained from wires, and their disadvantages are either short travel distances or inflexible travel routes. The present invention attempts to overcome the above-mentioned disadvantages.

Contents of the invention

The invention provides two vehicles or a series of vehicles, at least one of which is an electric vehicle. Both ends of each vehicle are equipped with a towing link frame, which can be removed, folded or retracted. The first vehicle is a tram/trolleybus with one end of the vehicle, such as the rear, having a socket system so that when the relevant part of the other vehicle is connected, power and traffic signals, driving signals and operating signals can be transmitted through wires to another vehicle.

Apart from the fact that the first vehicle was used as a non-electric vehicle, the performance of the two vehicles is the same, the only difference is that when used as a tram, the one that provides electricity has metal wheels. All necessary electric drive components and power supply components are available, including, inter alia, drive motor speed controllers, power regeneration, braking devices (such as regenerators), emergency brakes, automatic switches, system shifting devices, converters/inverters; AC/DC converters, removable antenna systems, electronic traffic signal transmitters, transmission and reception/control units, cooling fans for batteries and drive components, and gear drives. Each has a removable battery at one end (except for trams or vehicles that don't use electric fuel), and has solar panels on the roof.

The invention also includes an electric vehicle having an external removable battery mounted on removable metal/rubber wheels (as the case may be) and a dipole antenna mounted on similar wheels , the wheels have a conductive direction device, at least one wheel can be used as a discharge electrode to replace the antenna (when the situation requires). There are also rail guides, which prevent the vehicle from leaving the track when the vehicle is used on the tramway. There are accessory connectors/components including insulators, capacitors, recorders, electrode indicators/transducers, compression springs/suspensions for the wheels, and antenna height controls. Comes with attached catch/release and safety gear, plus charging unit and air conditioner. (Unique touches include having a roof-mounted battery with accessory brackets, along with power connections and gearshift).

Description of drawings

The present invention is described in detail according to accompanying drawing 1 now. Figure 1 is a perspective view of the side view of the EVDPU system, which uses a double-decker tram as a vehicle to provide electricity. According to the accompanying drawing, the EVDPU system is composed of the electric van truck 01 at the back and the tram 05 at the front. The electric vehicle 01 has an electronic controller and a signal receiving system, a detachable battery 02 and a detachable antenna system 03; the tram 05 has an electronic controller and a signal receiving system (including an automatic drive/operation signal transmitter), a towed Metal connection frames, power transmission devices, signal pipes/wires (not all of the above items are shown in Figure 1). The towable metal link bracket can be split in half so that each part can be retracted and folded into an upright position to lock to the vehicle body. The two parts are joined at the connection point by using the screw cap assembly. The power and signal tubes/wires are also split in half and connected by a socket system with screw cap couplings. (Auxiliary parts, including steering gear, will not be repeated here), (also roof solar panel 07 and battery.)

BEST MODE FOR CARRYING OUT THE INVENTION

The vehicle/tramcar 05 that provides electric power is connected to the vehicle 01 behind with a towed metal connection frame 04 . Using the antenna 03* of the tram, the power passes through the wires above to drive the drive system of the electric motor of the tram 05. The electric power is transmitted to the vehicle 01 through the built-in distributor of the electric car 05 for power transmission and storage battery charging. Through the electronic controller and signal device, the driving signal/operation signal is transmitted from the trolley 05 to the vehicle 01, so that the basic driving activities are automatically controlled by the front trolley 05, and an alarm signal is sent to the driver of the van truck when necessary. At the replacement point, the truck 01 is removed from the tram 05 and continues to move forward with additional power obtained by the power of the battery and the replacement of the battery. The removable storage battery has two metal arms 06 (the role is to act as the negative pole and the positive pole), which are installed at one end of the vehicle 01 (here, the back of the vehicle) **.

To remove battery 02, unscrew the support screws around the battery and loosen the other screws/locks at the same time, allowing the battery to be replaced. The screw has a disc/wheel at the protruding end with a small hole in it to allow the rod to be inserted. The metal arm 06 of the truck 01 has reversed socket/receiving holes for wires to pass through. In addition, there is an automatic locking device, and the body has corresponding screw holes for mounting battery reinforcement screws.

Note: *If the tram 05 is replaced by a trolleybus, then the antenna 03 of the tram is replaced with a double antenna system (referring to the 03' antenna in Figure 1).

** If the battery is not installed at the end of the car, it can also be installed on both sides of the chassis (solar panels can be removed and replaced by ordinary metal covers).

Note—1. There is an operation mode in which the electric van 01 is towed by a vehicle that does not use electric fuel. The regenerator of the vehicle 01 is switched by a signal to generate power for the battery 02 (and the battery 02').

2. The storage battery 02' is a supplementary rechargeable/non-rechargeable storage battery with a detachable device connected to the switching device to supply driving power.

3. There are buffer facilities between the front and rear cars, and there are buffers/regulators under the battery, but they are not specially marked.

4. If solar panels are used on trams, trolleybuses or buses with non-electric fuels (such as organic fuels), there are batteries for storing energy and a guide switch for direct transmission of power to another vehicle.
