The range extender system mainly includes an engine and a matching generator. The engine drives the generator to rotate, and the electricity generated can not only charge the battery, but also be directly output to the drive motor to participate in the drive. The range is greatly increased, and the pure electric vehicle is freed from the dependence on charging piles.

[0039] As mentioned in the background technology: With the current fossil energy crisis and the constraints of national environmental protection regulations, the automotive field is gradually developing rapidly in the direction of new energy, but pure electric vehicles are limited by the low energy density of batteries, and their range has always been "criticized". At the same time, the number of charging piles, grid load, etc. also limit the rapid development of pure electric vehicles. In this scenario, the automotive range extender system came into being. The range extender system mainly includes an engine and a matching generator. The engine drives the generator to rotate. The electricity generated can not only charge the battery, but also be directly output to the drive motor to participate in the drive. The range is greatly increased, and the pure electric vehicle is free from the dependence on charging piles.

One end of the three-phase wire is connected to the lead wire through the outlet, and the other end extends to the outside of the junction box and is connected to a controller.

[0041] Since the position of the outlet is fixed, the direction of the three-phase line is fixed after being installed on the outlet, so that the junction box can only be applied to a certain type of vehicle and cannot be applied to other types of vehicles.

[0042] In order to solve the technical problems raised above, the present application provides a range-extended generator and a vehicle, wherein the range-extended generator is provided with a housing, a stator, a rotor, a junction box, a terminal and a lead wire, the stator is fixedly installed in the housing, the rotor is rotatably installed in the housing, the rotor is configured to be connected to an external power part so that the rotor rotates relative to the stator and generates electricity under the action of an electromagnetic force, the junction box is installed on the housing, and the junction box is connected to the interior of the housing, the terminal is installed in the junction box, one end of the lead wire is connected to the stator, and the other end is connected to the terminal; The box has an opening on the side facing away from the shell, and the junction box has a box cover at the opening, which is detachably connected to the junction box.

When installing the range-extended generator on vehicles of different models, the installation direction of the box cover is adjusted according to the layout space of the vehicle; when the layout space at the rear end of the vehicle is limited, the box cover is connected to the junction box in the first installation position, and the wire outlet is facing the front end of the shell, and the range-extended generator will not be unable to be installed due to the limited layout space at the rear end of the vehicle; when the layout space at the front end of the vehicle is limited, the box cover is connected to the junction box in the second installation position, and the wire outlet is facing the rear end of the shell, and the range-extended generator will not be unable to be installed due to the limited layout space at the front end of the vehicle; thereby, the range-extended generator in the present application can be suitable for vehicles of different models.

[0043] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Among them, the rotor of the range-extended generator is used to be connected to the power parts of the vehicle. The rotor is installed in the shell. The front end of the shell refers to the end of the shell facing the power parts; the rear end of the shell refers to the end of the shell away from the power parts.

[0045] refer to Figure 1 and Figure 3 The embodiment of the present application discloses a range-extended generator, including a housing 100 , a stator 200 , a rotor 300 , a terminal box 400 , a terminal post 500 and a lead wire 600 .

[0046] The stator 200 is fixedly installed in the housing 100, the rotor 300 is rotatably installed in the housing 100, the terminal box 400 is installed on the housing 100, and the terminal box 400 is connected to the interior of the housing 100, the terminal post 500 is installed in the terminal box 400, one end of the lead wire 600 is connected to the stator 200, and the other end is connected to the terminal post 500.

[0047] The junction box 400 has an opening on one side facing away from the shell 100, and the junction box 400 has a box cover 700 at the opening. The box cover 700 is detachably connected to the junction box 400, and one side of the box cover 700 has a wire outlet 710, which is configured to connect a three-phase line, and the three-phase line is used to connect to the terminal 500.

[0048] The box cover 700 has two installation positions on the junction box 400. In the first installation position, the wire outlet 710 faces one side of the housing 100; in the second installation position, the wire outlet 710 faces the other side opposite to the housing 100.

[0049] Exemplarily, the stator 200 and the rotor 300 are coaxially installed in the housing 100, and the stator 200 is used to be connected to the power parts of the vehicle. The stator 200 rotates relative to the rotor 300 to generate electricity under the action of electromagnetics. The electric energy on the stator 200 is transmitted to the terminal 500 through the lead-out line 600. The three-phase line is used to transmit the electric energy on the terminal 500 to the controller, thereby realizing the power generation of the extended-range generator.

[0050] Exemplarily, the terminal 500 can be installed in the middle position of the junction box 400, or can be installed in a position close to one side of the junction box 400. Then the distance between the box cover 700 and the terminal 500 is different in the first installation position and the second installation position. Therefore, in the first installation position, the first three-phase line is selected to be connected to the terminal 500; in the second installation position, the second three-phase line is selected to be connected to the terminal 500.

[0051] Exemplarily, the junction box 400 and the box cover 700 may be snap-connected.

[0052] Exemplarily, when the box cover 700 is in the first installation position, the box cover 700 can be rotated 180 degrees around its center line to be in the second installation position.

[0053] Exemplarily, when the box cover 700 is in the first installation position, the wire outlet 710 faces the front end of the housing 100 , and when the box cover 700 is in the second installation position, the wire outlet 710 faces the rear end of the housing 100 .

[0054] By adopting the above technical solution, when the range-extended generator is installed on vehicles of different models, the installation direction of the box cover 700 is adjusted according to the layout space of the vehicle; when the layout space at the rear end of the vehicle is limited, the box cover 700 is connected to the junction box 400 in the first installation position, and the outlet port 710 is facing the front end of the shell 100, and the range-extended generator will not be unable to be installed due to the limited layout space at the rear end of the vehicle; when the layout space at the front end of the vehicle is limited, the box cover 700 is connected to the junction box 400 in the second installation position, and the outlet port 710 is facing the rear end of the shell 100, and the range-extended generator will not be unable to be installed due to the limited layout space at the front end of the vehicle; thereby, the range-extended generator in the present application can be suitable for vehicles of different models.

[0055] In some embodiments, the terminal post 500 is located in the middle of the junction box 400 so that the distance from the outlet 710 to the terminal post 500 is consistent when the box cover 700 is in the first installation position and the second installation position.

[0056] By adopting the above technical solution, the junction box 400 is installed above the shell 100, and the terminal 500 is installed in the middle of the junction box 400. When the box cover 700 is installed on the junction box 400 in the first installation position, the length of the wire outlet 710 from the terminal 500 is H. When the box cover 700 is installed on the junction box 400 in the second installation position, the length of the wire outlet 710 from the terminal 500 is also H, so that one type of three-phase line can pass through the wire outlet 710 to connect to the terminal 500.

[0057] In some embodiments, the box cover 700 has a plurality of connectors, and the box cover 700 is connected to the junction box 400 through the connectors.

[0058] Exemplarily, the connecting parts are bolts, and the box cover 700 has multiple bolt holes around it for the bolts to pass through, and the multiple bolt holes are symmetrically arranged with the center of the box cover 700. The junction box 400 has multiple mounting holes that match the bolt holes. After the box cover 700 is rotated 180 degrees about its center line, the bolt holes that follow the rotation can still match the mounting holes.

[0059] By adopting the above technical solution and providing the connecting piece, the box cover 700 can be easily installed and removed, thereby facilitating the adjustment of the installation direction of the box cover 700 according to different vehicle models.

[0060] In some embodiments, the range-extended generator further includes a front cover plate 800 , which is used to cover the front opening of the housing 100 .

[0061] Exemplarily, the front opening of the housing 100 is used for the stator 200 and the rotor 300 to pass through, so that the user can install the stator 200 and the rotor 300 into the housing 100 .

[0062] By adopting the above technical solution and providing the front cover plate 800 , the front opening of the housing 100 can be closed.

[0063] In some embodiments, the front cover plate 800 has a fixing piece, and the front cover plate 800 is connected to the housing 100 via the fixing piece.

[0064] Exemplarily, the fixing member is a bolt, and the housing 100 has a plurality of bolt holes, and the bolts pass through the front cover plate 800 and are threadedly connected to the bolt holes.

[0065] By adopting the above technical solution and providing fixing parts, it is convenient to install and remove the front cover plate 800 from the housing 100, thereby facilitating the subsequent maintenance of the components in the housing 100.

[0066] In some embodiments, the lead wire 600 is connected to the stator 200 at the front side.

[0067] By adopting the above technical solution, after the front cover 800 is connected to the shell 100, a channel is provided between the front cover 800, the shell 100 and the junction box 400, and the lead wire 600 can pass through the channel, so that the lead wire 600 can transmit the electric energy on the stator 200 to the terminal 500, and there is no need to separately design a channel on the rear side of the shell 100 for the lead wire 600 to pass through, thereby minimizing the length of the shell 100 in the front-to-back direction, thereby realizing the lightweight development of the extended-range generator.

[0068] In some embodiments, the stator 200 and the rotor 300 are located at the rear side of the housing 100 .

[0069] By adopting the above technical solution, the lead wire 600 passes through the channel between the front cover plate 800, the shell 100 and the junction box 400. However, since the electric energy on the lead wire 600 is high voltage electricity, it is necessary to make the channel have sufficient creepage distance. Therefore, the stator 200 and the rotor 300 can be moved to the rear side inside the shell 100, so that the width of the channel is larger, ensuring that there is sufficient creepage distance in the channel and ensuring the safety of high voltage electricity.

[0070] In some embodiments, the range-extended generator further includes a connecting shaft 900 , which is rotatably mounted in the housing 100 , and the connecting shaft 900 is used to connect to the rotor 300 .

[0071] Exemplarily, the rotor 300 has a shaft hole, and the connecting shaft 900 is inserted into the shaft hole with interference fit.

[0072] By adopting the above technical solution and providing the connecting shaft 900 , it is convenient to install the rotor 300 in the housing 100 .

[0073] In some embodiments, the range-extended generator further includes a bearing 910 , which is installed in the housing 100 , and the connecting shaft 900 is rotatably connected to the housing 100 via the bearing 910 .

[0074] Exemplarily, the bearing 910 has a mounting hole, and the connecting shaft 900 is inserted into the mounting hole with interference fit.

[0075] By adopting the above technical solution and providing the bearing 910 , the friction resistance of the housing 100 during rotation is reduced.

[0076] An embodiment of the present application also discloses a vehicle, comprising a vehicle body and any one of the range-extended generators of the above embodiments, wherein the range-extended generator is mounted on the vehicle body.

[0077] Among them, the structure and principle of the extended-range generator have been clearly explained in the above embodiments and will not be elaborated here one by one.

[0078] By adopting the above technical solution, when the range-extended generator is installed on vehicles of different models, the installation direction of the box cover 700 is adjusted according to the layout space of the vehicle; when the layout space at the rear end of the vehicle is limited, the box cover 700 is connected to the junction box 400 in the first installation position, and the outlet port 710 is facing the front end of the shell 100, and the range-extended generator will not be unable to be installed due to the limited layout space at the rear end of the vehicle; when the layout space at the front end of the vehicle is limited, the box cover 700 is connected to the junction box 400 in the second installation position, and the outlet port 710 is facing the rear end of the shell 100, and the range-extended generator will not be unable to be installed due to the limited layout space at the front end of the vehicle; thereby, the range-extended generator in the present application can be suitable for vehicles of different models.
