Detailed Description

As shown in figures 1-4, referring to figures 1 and 2, the energy-saving and environment-friendly electric vehicle comprises

An internal combustion engine 100 for burning fossil fuels;

a generator 200 having an input shaft fixed to an output shaft of the internal combustion engine 100;

a battery 300 connected to an output terminal of the generator 200;

a motor 400 connected to an output terminal of the battery 300;

a foot board 700 disposed on the lower side of the cabin;

a controller 600 for connecting the generator 200 and the battery 300 together with an input terminal of the motor 400 when the internal combustion engine is operated and an opening/closing angle of the foot pedal 700 exceeds a first preset threshold.

The invention is different from the prior art that only the battery 300 supplies power to the motor 400, but when the opening and closing angle of the pedal plate 700 exceeds a first preset threshold value, the generator 200 and the battery 300 are used together for driving the motor 400 to rotate, so that greater power can be provided for a vehicle in a short time, and the vehicle can pass or pass through high-difficulty terrain.

Compared with a fuel vehicle, the invention can realize the power of the large-displacement internal combustion engine by using the internal combustion engine with smaller displacement, thereby realizing the functions of energy conservation and environmental protection. Compared with a pure electric vehicle, the invention can use the internal combustion engine 100 to drive the generator 200 to charge the battery, and has better endurance mileage and replenishment speed. Compared with an electric hybrid vehicle, the hybrid vehicle has the advantages that the internal combustion engine 100 is not directly connected with the wheels through the gearbox, so that the cost of the gearbox is saved, and the manufacturing cost of the whole vehicle is lower.

Wherein the first preset threshold may be 60% or 70% or 80% or 90% of the full stroke of the foot pedal 700.

An output shaft of the internal combustion engine 100 is connected with an input shaft of a generator 200, an output end of the generator 200 is connected with an input end of the battery 300 through a conducting wire, an output end of the battery 300 is connected with an input end of the motor 400, and an output shaft of the motor 400 is in transmission connection with the axle 500. Wherein, the output shaft of the motor 400 can be coaxially fixed with the axle 500, and the axle 500 is fixed with the wheel, so as to realize the transmission and conversion of the energy.

and an axle 500 for outputting the second mechanical energy.

Preferably, when the charge of the battery 300 is lower than a second preset threshold, the controller 600 controls the internal combustion engine 100 to start and drive the generator 200 to generate electricity.

The present invention determines that the internal combustion engine 100 drives the generator 200 to generate power by the second threshold value, so that the battery 300 supplies power to the motor 400 only by its own power amount in a state where the power amount is high, and does not supply power to the motor 400 by the generator 200, thereby achieving lower emissions and less fuel consumption.

The second predetermined threshold may be 30%, 40%, 50% or 60% of the charge of the battery 300.

Preferably, referring to fig. 2 and 3, the internal combustion engine 100, the generator 200, the battery 300, the motor 400, and the controller 600 are all connected to a vehicle frame 800, the axle 500 is mounted on the vehicle frame 800 through a bearing, the vehicle frame 800 is fixed to one end of a first link 801, the other end of the first link 801 is mounted with a pedal 700 through a bearing, the controller 600 includes a horn block 601, a first swing link 602, a second link 603, an arc-shaped rod 604, a first switch 605, a second switch 606, a first permanent magnet 607, a second permanent magnet 608, a first shaft 609, a third link 610, and a processor 611, the pedal 700 is coaxially fixed with the horn block 601, an outer arc-shaped surface of the horn block 601 is overlapped with one end of the first swing link 602, the other end of the first swing link 602 is fixed to a first shaft 609, the first shaft 609 is mounted on the second link 603 through a bearing, the second link 603 is fixed to the first link 801, the first shaft 609 is fixed to the middle of the arc rod 604, one end of the arc rod 604 can be in contact with the first switch 605, the other end of the arc rod 604 can be in contact with the second switch 606, the first switch 605 and the second switch 606 are both fixed to the third connecting rod 610, the third connecting rod 610 is fixed to the first connecting rod 801, a first permanent magnet 607 is fixed to one side of the arc rod 604 close to the second switch 606, a second permanent magnet 608 is fixed to a position of the third connecting rod 610 close to the second switch 606, the first switch 605 and the second switch 606 are both connected to a processor 611, and the processor 611 is fixed to the frame 800;

when the arc-shaped rod 604 is not in contact with the first switch 605 and the second switch 606, the processor 611 determines that the generator 200 is not connected with the motor 400, and the output end of the battery 300 is connected with the motor 400;

The controller 600 in the above manner of the present invention replaces the conventional method of detecting the state of the foot pedal 700 only by a single chip microcomputer, and instead, a more mechanized and reliable structural controller 600 is used to control the connection among the internal combustion engine 100, the motor 400 and the battery 300, which has a more direct and faster signal response than directly determining the formation of the foot pedal 700 by an on-board processor, so as to make a faster response speed by the same processor. In addition, the phenomenon that no signal corresponds to the processor due to dead halt when the processor runs signal processing is avoided.

Wherein, in order to make the pedal 700 have a larger stroke interval, it is avoided that the pedal cannot be pressed after the arc rod 604 contacts the second switch 606; the curved rod 604 may be made of a flexible material, and the curved rod 604 may be made of: rubber, plastics, iron, silica gel, titanium and titanium alloy materials of glasses legs. It is worth mentioning that the curved rod 604 may be thin-sheet-like or thread-like in order to provide a certain flexibility.

The first switch 605 and the second switch 606 may be contact switches or push switches, and when they are contacted with the arc rod 604, they output contact signals to the processor 611, so that the processor 611 can sense that they are contacted.

The third link 610 may be a bent rod, so that the buttons of the first switch 605 and the second switch 606 face the arc-shaped rod 604, and the third link 610, the first link 801 and the second link 603 may be structures in a cabin of an automobile, which may be a wall surface of the cabin or a separate rod body, and are described as rods only for the sake of clarity of functions, and any structure using a wall surface should also fall into the present invention.

Wherein, wheels are provided on both sides of the axle 500.
