Description

Technical Field

[0001] This utility model relates to the field of range-extended electric vehicle power system technology, and in particular to an integrated range extender assembly and a range-extended electric vehicle. Background Technology

[0002] Range-extended electric vehicles are hybrid vehicles that fall between pure electric vehicles and traditional gasoline vehicles. They use an electric motor as the main drive source, with the engine acting as a range extender and not directly driving the wheels. When the battery is fully charged, the car is driven by pure electric power. When the battery is low, the range extender is activated to generate electricity and extend the battery's driving range.

[0003] The range extender assembly, as the power generation mechanism of a range-extended electric vehicle, is responsible for replenishing the power battery and mainly consists of a generator, engine, and controller. In existing technologies, range extender assemblies are arranged in two ways: centralized and separate. In the traditional centralized arrangement, the generator and drive motor use an independent hybrid box, which is then axially connected to the engine via a spline. This occupies a large amount of space in the vehicle's Y-axis, making it unfavorable for overall vehicle layout. In the separate arrangement, the engine and generator form the range extender, which is separate from the drive motor and arranged front-to-rear in the vehicle layout. A certain clearance must be maintained between the range extender and the drive motor, occupying a large amount of space in the vehicle's X-axis. Furthermore, the separate arrangement of the range extender assembly requires two sets of mounting brackets to support the range extender, increasing costs. Utility Model Content

[0004] This utility model provides an integrated range extender assembly and a range-extended electric vehicle to solve the technical problem that the existing range extender assembly layout occupies a large space and is not conducive to the overall vehicle layout.

[0005] The integrated range extender assembly and range-extended electric vehicle provided by this utility model include an engine, a generator, a generator controller, a distributed motor, and a distributed motor controller. The engine, the generator, and the generator controller are arranged sequentially along the Y direction and integrated into a range extender power generation module. The distributed motor and the distributed motor controller are arranged with the range extender power generation module along the X direction and integrated into the integrated range extender assembly. Wherein, the X direction is the front-to-back direction of the vehicle, and the Y direction is the left-to-right direction of the vehicle.

[0006] In one embodiment of this utility model, the distributed motor and the distributed motor controller are arranged and integrated along the Z direction, and then integrated with the range extender power generation module along the X direction, wherein the Z direction is the vertical direction of the vehicle.

[0007] In one embodiment of the present invention, a mounting mechanism is further included, which is used to mount the integrated range extender assembly in the engine compartment of the vehicle.

[0008] In one embodiment of the present invention, the suspension mechanism includes a first upper suspension, a second upper suspension, a first lower suspension, and a second lower suspension.

[0014] This utility model also provides a range-extended electric vehicle, including the integrated range extender assembly described in any of the above claims; and, The vehicle body, on which the integrated range extender assembly is mounted.

[0015] The beneficial effects of this utility model are as follows: The integrated range extender assembly and range-extended electric vehicle proposed in this utility model integrate the engine, generator, and generator controller along the Y-axis, and then integrate them with the distributed motor and distributed motor controller along the X-axis.

This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] The specific structure of the integrated range extender assembly in this utility model is described in conjunction with [reference needed]. Figures 1 to 3 The integrated range extender assembly includes an engine 1, a generator 2, a generator controller 3, a distributed motor 5, and a distributed motor controller 6. The engine 1, the generator 2, and the generator controller 3 are arranged sequentially along the Y direction and integrated into a range extender power generation module 4. The distributed motor 5 and the distributed motor controller 6 are arranged with the range extender power generation module 4 along the X direction and integrated into the integrated range extender assembly. Herein, the X direction is the front-to-back direction of the vehicle, and the Y direction is the left-to-right direction of the vehicle.

[0023] Among them, engine 1, generator 2, generator controller 3, distributed motor 5 and distributed motor controller 6 are specific components that constitute the range extender assembly. They are all existing components, so their specific structure and function will not be described in detail here.

[0024] In the vehicle coordinate system, the X-axis refers to the longitudinal direction of the vehicle (front-to-back direction), and the positive direction of the X-axis points to the front of the vehicle, which is the direction of the vehicle's movement; the Y-axis refers to the lateral direction of the vehicle (left-to-right direction), and the positive direction of the Y-axis points to the left side of the vehicle (the driver's left-hand side); the Z-axis refers to the vertical direction of the vehicle (up-down direction), and the positive direction of the Z-axis points to the roof of the vehicle. Figure 1 and Figure 3 In the diagram, the arrow marked with X points in the positive X direction (towards the front of the car), while the arrow marked with Y points in the Y direction (towards the left side of the car).

[0025] In practical implementation, the integrated range extender assembly in this solution integrates the engine 1, generator 2, and generator controller 3 in the Y-axis, and then integrates them with the distributed motor 5 and distributed motor controller 6 in the X-axis. This layout makes the overall structure more compact and makes full use of the space in the vehicle's engine compartment during assembly. Compared to traditional centralized range extender assemblies, it occupies less space in the Y-axis, which is more conducive to vehicle layout. Compared to split-type range extender assemblies, it occupies less space in the X-axis, which is more conducive to vehicle layout. At the same time, the integrated range extender assembly in this solution is a single unit, eliminating the need for multiple mounting brackets for support, effectively reducing costs.

[0026] In some embodiments, the distributed motor 5 and the distributed motor controller 6 are arranged and integrated along the Z-axis, and then integrated with the range extender generator module 4 along the X-axis, where the Z-axis is the vertical direction of the vehicle. For example, Figure 2 As shown, the distributed motor 5 and the distributed motor controller 6 are integrated in the vertical direction, which can further make the integrated range extender assembly structure more compact.

[0027] In some embodiments, a mounting mechanism is also included for mounting the integrated range extender assembly in the engine compartment of the vehicle. For example, Figure 1 As shown, in this solution, the integrated range extender is a whole unit, requiring only one suspension mechanism for fixation, which reduces space occupation and overall cost.

[0028] In some embodiments, the suspension mechanism includes a first upper suspension 7, a second upper suspension 8, a first lower suspension 9, and a second lower suspension 10, which are arranged around the integrated range extender assembly for securing the integrated range extender assembly within the vehicle's engine compartment. For example, Figure 1 As shown, the integrated range extender assembly is fixed in the engine compartment of the car by the first upper mount 7, the second upper mount 8, the first lower mount 9, and the second lower mount 10 around the integrated range extender assembly, which can securely install the integrated range extender assembly.

[0029] In some embodiments, the first upper mount 7 and the second upper mount 8 are disposed on the upper part of the integrated range extender assembly, and the first lower mount 9 and the second lower mount 10 are disposed on the lower part of the integrated range extender assembly. For example, Figure 1 As shown, this arrangement allows the integrated range extender assembly to be more stably fixed in the vehicle's engine compartment.

[0030] The first upper mount and the first lower mount are disposed on one side of the integrated range extender assembly, and the second upper mount and the second lower mount are disposed on the other side of the integrated range extender assembly. For example, Figure 1 As shown, this arrangement allows the integrated range extender assembly to be evenly distributed across the mounting points within the vehicle's engine compartment.

[0031] In some embodiments, the first upper mount 7 and the second upper mount 8 are fixed to the longitudinal beam of the vehicle, and the first lower mount 9 and the second lower mount 10 are fixed to the subframe of the vehicle. Specifically, this allows the integrated range extender assembly to be securely fixed inside the engine compartment of the vehicle.

[0032] In some embodiments, the range extender generator module 4 integrates the distributed motor 5 and the distributed motor controller 6 via bolt connections. For example, Figures 1 to 3 As shown, threaded connections are inexpensive and easy to assemble, and also ensure a secure connection between the distributed motor 5 and the distributed motor controller 6.

[0033] In some embodiments, the engine 1, the generator 2, and the generator controller 3 are integrated by bolt connection. Specifically, threaded connection is inexpensive and easy to assemble, and also ensures a secure connection between the engine 1, generator 2, and generator controller 3.

[0034] In some embodiments, the present solution also provides a range-extended electric vehicle, including the integrated range extender assembly described in any of the preceding claims; and a vehicle body having an engine compartment, wherein the integrated range extender assembly is mounted in the engine compartment.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
