Description

Self-driven self-generating electric vehicle chassis

Technical Field

Relates to an electric vehicle chassis device, in particular to an electric vehicle running chassis which is capable of generating power by itself, charging by itself and completing power supply of ultra-long endurance mileage, and belongs to the technical field of new energy electric vehicle manufacturing.

Background

The endurance mileage (new car) of various electric vehicles is about within 400 kilometers at present, the endurance mileage is gradually reduced along with the increase of the age of the electric vehicle, the aging of a storage battery and the reduction of outdoor temperature in winter, electric energy supplement is completely needed to be carried out by using a charging pile every day, and two modes of stopping the electric vehicle to carry out slow charging (9 hours) and fast charging (1 hour) are adopted. But the quick charging can cause certain harm to the storage battery of the electric vehicle. In addition, charging requires a high amount of electricity (generally, 40 degrees of electricity charging requires about 40 yuan of electricity at home, 80 yuan of electricity charging at a public charging post, and 200 km can be driven, and if the capacity of the storage battery is larger, more electricity is required for charging). With the increasing application quantity of the electric vehicles and the limitation of the quantity and popularization of the charging piles (for example, when the electric vehicles need to be charged when running on non-highways, remote mountainous areas, deserts, grasslands, small cities, counties and villages, the phenomenon that the charging piles are difficult to search and wait for charging in line inevitably occurs.)

In summary, the self-driven self-generating electric vehicle chassis can completely solve the technical problems.

Disclosure of Invention

In order to finish the running of the electric vehicle with ultra-long endurance mileage; the electric energy is supplemented without stopping the vehicle during running; the chassis of the invention adopts 10 or 12 generators (the number of the generators is set according to the power of the motor), and the structure for charging two groups of storage batteries (namely, the A storage battery pack and the B storage battery pack) is switched at any time according to the electricity storage information prompt of an instrument system.

Before the electric vehicle needs to run, the group A storage battery or the group B storage battery is controlled by a selector switch, any one storage battery pack supplies power to the driving motor, so that the electric vehicle is driven to run, at the moment, one group (for example, the group B storage battery pack) which displays relatively high stored electric quantity supplies power to the driving motor, and the other group (the group A storage battery pack) which stores relatively low stored electric quantity charges the driving motor through 10 or 12 generators. If the electric vehicle runs for a period of time, the meter system displays that the charged A storage battery pack is fully charged, namely, the meter system is switched to drive the electric vehicle to run by the just-fully-charged A storage battery pack through the switch, and simultaneously, the other B storage battery pack is switched to be charged by the 10 or 12 generators. When the instrument system displays that the B storage battery pack is fully charged, the B storage battery pack is switched to supply power to the driving motor to drive the driving motor to run, and the generator charges the other A storage battery pack. The reciprocating operation is carried out in this way, and the ultra-long endurance and self-charging technology of the electric vehicle is achieved.

In addition, the invention also has a power plug port for charging the charging pile, and can also carry out conventional charging when parking.

Technical problem to be solved

The technical problems to be solved by the invention are as follows: the first is the problem of short endurance mileage of the electric vehicle caused by the prior art; secondly, the problem that the electric vehicle needs to stop to charge in the prior art is solved; thirdly, when the electric vehicle runs on a non-expressway, a remote mountain area, a desert, a grassland, a small city, a county city and a country, the electric vehicle needs to be charged and is difficult to search for a charging pile and queue for charging; fourth, the charging time is long (about 1 hour for fast charging and about 9 hours for slow charging).

The technical scheme is as follows:

the technical scheme is understood with reference to the description of the attached drawings in the specification!

In the technical chassis, two groups of storage batteries (an A storage battery pack 36 and a B storage battery pack 37) are connected with a driving motor through an inverter lead to drive a rear driving axle and a driving wheel to finish running and a front driving axle to finish steering; the double-drive axle generates electricity and the drive shaft drives the generator to generate electricity. Namely: according to the requirement of the required driving force of the electric vehicle, the rear driving axle drives the driving wheel of the electric vehicle to drive the electric vehicle to run and drive the generator to generate electricity to charge the storage battery pack of the electric vehicle. Since the electric energy of the electric vehicle driving motor is supplied through the inverter by the a battery pack 36 or the B battery pack 37 (in the prior art, the electric power is supplied to the motor by one battery pack), the technology adopts the technology that the a or B battery packs can be switched at any time and supply power to the driving motor respectively. This is one of the technologies for achieving ultra-long endurance.

Since two groups of storage batteries respectively supply electric energy to the driving motor, an independent technology for supplementing the electric energy to the storage batteries is needed (in the prior art, the electric vehicle is charged through a charging pile when the electric vehicle stops, the electric vehicle is fully charged in about 1 hour in a quick charging mode and is fully charged in about 9 hours in a slow charging mode, and if the electric vehicle runs on a non-expressway, a remote mountain area, a desert, a grassland, a small city, a county or a country, the phenomena that the charging pile is difficult to search and the electric vehicle is difficult to queue for charging inevitably occur). Therefore, the technology adopts the technology of automatically charging the storage battery pack of the vehicle in the driving process: that is, the internal diameters of the front drive axle and the rear drive axle of the vehicle are increased, the stator magnet and the winding coil are fixedly arranged in the internal diameters to form a stator, and the rotor magnet and the winding coil are fixedly arranged on the first drive shaft 6, the second drive shaft 9, the third drive shaft 14 and the fourth drive shaft 17 to form a rotor. And 6 or 8 generators are additionally arranged on two sides of the driving shaft generator. Thus, the running of the electric vehicle causes 10 or 12 vehicle-mounted generators to charge the storage battery pack during running, namely: a first driving shaft generator 19, a second driving shaft generator 23, a third driving shaft generator 25, a fourth driving shaft generator 28 (because the four generator driving shafts are rotors and the driving shell is a stator, the electric vehicle can generate electricity as long as running) and drives the first generator 20, the second generator 21, the third generator 22, the fourth generator 24, the fifth generator 26, the sixth generator 27, the seventh generator 29, the eighth generator 30, etc. to generate electricity, wherein the third driving shaft 14 and the fourth driving shaft 17 of the electric vehicle are respectively connected and driven by a third driving shaft generator belt pulley and a triangle belt 13, a fourth driving shaft generator belt pulley and a triangle belt 16 and a first generator 20, a second generator 21, a third generator 22 and a fourth generator 24 double-groove A-shaped belt pulley which are transversely fixed on the front driving axle shell, 2 or 4 generators are used for generating electricity. The first driving shaft 6 and the second driving shaft 9 of the electric vehicle are respectively connected and driven by a first driving shaft generator belt pulley and a triangle belt 5, a second driving shaft generator belt pulley and a triangle belt 8 and a fifth generator 26, a sixth generator 27, a seventh generator 29 and an eighth generator 30 which are transversely fixed on a rear driving axle shell, so that 4 generators generate electricity), and 10 or 12 generators are used for respectively charging two storage battery packs.

Meanwhile, a first driving shaft 6, a second driving shaft 9, a third driving shaft 14 and a fourth driving shaft 17 of the electric vehicle are utilized to drive a first electric vehicle wheel 7, a second electric vehicle wheel 10, a third electric vehicle wheel 15 and a fourth electric vehicle wheel 18 to rotate so as to drive the electric vehicle to run.

In this way, the present technology charges and supplies power to the a battery pack 36 and the B battery pack 37 and the inverter 1 in series or in parallel by 10 or 12 generators, such as the first drive shaft generator 19, the second drive shaft generator 23, the third drive shaft generator 25, the fourth drive shaft generator 28, the first generator 20, the second generator 21, the third generator 22, the fourth generator 24, the fifth generator 26, the sixth generator 27, the seventh generator 29, and the eighth generator 30. This process is called self-generating self-charging process!

In addition, the invention also has a plug-in port for charging the charging pile, and can be used for charging the A storage battery pack 36 and the B storage battery pack 37 normally when the vehicle is parked.

Has the advantages that:

compared with the prior art, the technology can completely solve the problems that: the endurance mileage is gradually reduced along with the increase of the age of the vehicle, the aging of the storage battery and the reduction of the outdoor temperature in winter. The problem that the electric vehicle needs to use the charging pile every day completely to supplement electric energy can be solved, and two modes of stopping the vehicle to charge slowly and charging quickly are adopted. But also solves the problem that the quick charging can cause certain harm to the battery of the electric vehicle. The problem of high electricity charge for charging is solved. The problem of along with the application quantity of electric motor car increase gradually and fill the quantity of electric pile and when popularized limitation, it is difficult and the phenomenon of waiting in line to charge to look for the electric pile of filling is still solved.
