Description

Technical Field

[0001] The utility model relates to a range-extending generator, belonging to the field of generators. Background Art

[0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. Electric vehicles are vehicles that use onboard power as power, use motors to drive wheels, and comply with various requirements of road traffic and safety regulations. As their impact on the environment is relatively small compared to traditional vehicles, their prospects are widely optimistic.

[0003] Since pure electric vehicles do not emit any pollutants when driving, but the current power storage technology cannot guarantee sufficient power reserves for the vehicle itself, the short cruising range is a fatal weakness. In order to make up for this weakness and provide electric vehicles with a more continuous power supply, it is usually practiced to install a range-extending generator in the electric vehicle. However, the temperature of the range-extending generator in the existing technology is too high, causing the power of the motor to not meet the actual power requirements of the vehicle. In addition, the high temperature of the motor may demagnetize the permanent magnet of the rotor, causing the motor to malfunction and the vehicle to be unable to drive normally.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: an extended-range generator, comprising a circular generator shell 1, a stator is arranged in the generator shell 1, a rotor 2 is also arranged on the generator shell 1, a front cover 3 is installed at the front end of the generator shell 1, a tail cover is installed at the rear end of the generator shell 1, a circulation pipe 4 is arranged inside the generator shell 1, a water inlet pipe 5 and a water outlet pipe 6 that penetrate the generator shell 1 are arranged on the circulation pipe 4, a junction box 7 is arranged on the generator shell 1, the circulation pipe 4 includes a plurality of annular pipes 8, and the annular pipes 8 are connected by a plurality of connecting pipes 9, the generator shell 1 includes an inner shell 14 and an outer shell 15, an inner wall of the inner shell 14 is provided with an inlay groove 10, the annular pipe 8 is inlaid in the inlay groove 10, an inner wall of the inner shell 14 is also provided with a secondary inlay groove 11, and the connecting pipe 9 is inlaid in the secondary inlay groove 11.

[0025] See also Figure 1 The stator includes a stator core and a stator winding. A full-wave rectifier is integrated in the generator housing 1. The full-wave rectifier is a six-phase full-wave rectifier. The full-wave rectifier processes the high-frequency and medium-frequency electricity output by the stator of the generator and converts it into constant-voltage direct current to output to the battery pack of the electric vehicle.

[0026] See also Figure 3-4The inner side of the annular tube 8 is fixedly provided with an annular heat exchange plate 12, and the heat exchange plate 12 is a copper heat absorbing plate. The outer surface of the connecting tube 9 is fixedly provided with an arc-shaped auxiliary heat exchange plate 13, and the auxiliary heat exchange plate 13 is a copper heat absorbing plate. The heat exchange plate 12 and the auxiliary heat exchange plate 13 themselves have a good heat absorption effect, and cooperate with the coolant to exchange heat, thereby achieving a cooling effect.

[0027] See also Figure 5-6 A soundproof space is formed between the inner shell 14 and the outer shell 15, four fixing plates 16 are fixedly arranged between the inner shell 14 and the outer shell 15, and the soundproof space is divided into a plurality of auxiliary soundproof spaces 17 by the fixing plates 16. Sound holes 18 are evenly arranged on the inner wall of the inner shell 14, two elastic sheets 19 are fixedly arranged between adjacent fixing plates 16, and auxiliary sound holes are evenly opened on the elastic sheets 19. A soundproof cotton layer 20 is pasted on the inner wall of the outer shell 15, and auxiliary soundproof cotton layers 21 are pasted on the inner sides of the elastic sheets 19. An auxiliary elastic sheet 22 in an eight-shaped shape is also fixed on the inner side of the elastic sheet 19.

[0028] The generator shell 1 is divided into an inner shell 14 and an outer shell 15, and a soundproof space is formed between the inner shell 14 and the outer shell 15. When the motor is working, the noise generated enters the soundproof space through the sound-permeable holes 18 on the inner wall of the inner shell 14, and then is layered by the auxiliary soundproof cotton layer 21 on the double elastic sheet 19. The design of the elastic sheet 19 can rebound the sound, and the auxiliary elastic sheet 22 designed is used to enhance the buffering and rebound of the sound, so that the sound can be dissipated multiple times, and finally the sound insulation cotton layer 20 and the auxiliary sound insulation cotton layer 21 are used for the final silencing to ensure a good sound reduction effect.

[0029] During specific operation, the water inlet pipe 5 and the water outlet pipe 6 are used to supply and discharge the liquid, and the coolant is discharged into the circulation pipe 4, that is, into the annular pipe 8. Since the annular pipes 8 are connected by the connecting pipe 9, the circulating coolant is distributed inside the annular pipe 8 and the connecting pipe 9. When the rotating parts inside the generator shell 1 are in use, there is a certain amount of heat inside the shell, and the heat contacts the annular pipe 8 and the connecting pipe 9, thereby achieving a cooling and heat exchange effect, making the internal temperature of the motor too high, ensuring that the power of the motor meets the actual power demand of the vehicle.

[0030] Rotor 2 is a multi-pole rotor with a permanent magnet structure. If the motor temperature is too high, the rotor permanent magnet may be demagnetized, the motor may fail, and the vehicle may not be able to drive normally. Therefore, heat exchange and cooling are designed to ensure that the internal temperature of the motor is not too high.

[0031] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
