Problems solved by technology

[0002] With the improvement of people's awareness of environmental protection, electric vehicles using lithium batteries have begun to enter thousands of households. Due to the limitations of lithium battery technology and performance, there are still two main problems in electric vehicles: First, the cruising range of lithium batteries is limited. , Correspondingly, the charging time of lithium batteries is long, and it is impossible to achieve fast charging like refueling, and the number of suitable charging piles is limited, resulting in troublesome charging. The above technical problems limit the popularization of electric vehicles
[0003] However, the existing range extenders have the following technical defects: On the one hand, due to the large size of the battery on the electric vehicle, the battery is usually installed in the trunk of the car body and the front cabin, which will cause tension in the installation space in these areas
On the other hand, the range extender also needs to be equipped with a small engine, which leads to more crowded installation space
In the prior art, people usually connect the engine and the generator coaxially in series to simplify the structural design and layout, but this will increase the axial size of the entire range extender, which in turn causes inconvenience and difficulty in installing the range extender on the car

Embodiment 1

[0059] Embodiment 1: as figure 1 As shown, an assembled generator, which is suitable for the range extender of electric vehicles, specifically includes a motor housing 1, a rotor shaft 2 arranged in the motor housing, a junction box 7 for connecting input and output cables, a control 15, the rotor 4 and the stator winding 3 are sequentially arranged in the motor housing in the axial direction of the rotor shaft. They are sequentially arranged in series in the axial direction, so as to facilitate the user's assembly. The transfer box facilitates the electrical connection between the stator winding and the charger or other electrical equipment.

[0060] As those skilled in the art should know, the two ends of the rotor can form an end surface magnetic field, and the magnetic force lines output from one end and return to the other end. Therefore, when the rotor shaft is driven by the output shaft of the engine to rotate, and then drives the rotor to rotate, the rotor rotates re...

Embodiment 2

[0076] Embodiment 2: a kind of range extender, such as Figure 4 , Figure 5 As shown, it includes an engine 10 with an outer casing 101 and an output shaft 102, and a double-stator generator as described in Embodiment 1. The rotor shaft of the generator is connected to the output shaft of the engine, and the connection end of the motor casing is connected to the casing of the engine. body connected. Specifically, the assembly of the range extender includes the following steps:

[0077] a. Install the stator windings into the first housing and the second housing respectively, the stator windings are lower than the openings of the first housing and the second housing, so that at the openings of the first housing and the second housing Form a concave semi-installation cavity;

[0078] b. Connect the rotor shaft with the output shaft of the engine, and fix the connecting end of the first casing on the outer casing of the engine, and at this time, the rotor shaft passes through...

Embodiment 3

[0092] Embodiment 3: a kind of range extender, such as Figure 10 As shown, it includes an engine with an outer casing and an output shaft, and a dual-rotor generator as described in Embodiment 1. The output shaft of the engine is connected to the rotor shaft of the generator, and one end of the motor casing of the generator is connected to the outer casing of the engine. connect. When the engine is running, the output shaft can drive the rotor shaft to rotate, and then realize the power generation of the assembled generator, and the electricity generated by the assembled generator can charge the battery of the electric vehicle, so as to satisfy the driving of the electric vehicle. Specifically, the assembly of the range extender system includes the following steps:

[0093] a. Install the first mounting bracket with magnetic steel on the front side of the rotor shaft, and let the front end of the rotor shaft pass through the center hole of the first housing. At this time, th...
