Description

Technical Field

[0001] This invention relates to the field of electric drive structure technology, and in particular to a modular electric drive control and auxiliary system, assembly system and automobile. Background Technology

[0002] With the development of new energy electric vehicles, related electric drive technologies have also improved rapidly, and the application of electric drives is becoming increasingly common across different vehicle models and with varying installation boundaries. While the performance parameters of the electric motors and reduction mechanisms in electric drive systems are generally consistent across different vehicle models, the different installation boundaries, such as chassis and body structures, result in a wide variety of system layouts within the electric drive assembly. This includes various configurations of the input and output shafts in the electric drive assembly, such as horizontal and vertical arrangements.

[0003] In relevant technical solutions, such as Figure 1 As shown, the drive motor is located in front of the half-shaft. In the electric drive assembly, the input and output shafts are arranged horizontally. In the control and auxiliary system, the motor controller and other devices are respectively located on both sides of the drive motor; as shown... Figure 2 As shown, the drive motor is located behind the half-shaft. In the electric drive assembly, the input and output shafts are arranged vertically. Similarly, the motor controller and other devices in the control and auxiliary system are also located on both sides of the drive motor. The relevant devices in the control and auxiliary system require continuous adjustment based on different vehicle models and different installation boundaries. The overall control and auxiliary system has poor versatility, resulting in excessive development resource requirements and a long development cycle. Summary of the Invention

[0004] This invention provides a modular electric drive control and auxiliary system to solve the technical problem that the control and auxiliary system has poor versatility and cannot adapt to different vehicle models and different installation boundaries, resulting in excessive development resource requirements and excessively long development cycles.

[0005] This invention provides a modular electric drive control and auxiliary system, which includes a motor controller system and an auxiliary system. The motor controller system has a motor controller housing, in which a motor controller is installed. The auxiliary system has an auxiliary system housing, in which a filter system, an oil pump system, and a first radiator are installed. The motor controller system and the auxiliary system are adjacent to each other.

[0006] Furthermore, the motor controller system and the auxiliary system share the same housing.

[0007] Furthermore, the filtration system, the oil pump system, and the first radiator are arranged sequentially and adjacent to each other within the auxiliary system housing.

[0008] Furthermore, heat dissipation fins are provided between the motor controller system and the auxiliary system.

[0010] Furthermore, the oil pump system also has an oil chamber, and the controller cooling water pipe is adjacent to the oil chamber.

[0011] Furthermore, the motor controller system also includes a second radiator, which is connected to the controller's cooling water pipe to assist the controller's cooling water pipe in dissipating heat.

[0012] This invention provides a modular electric drive assembly system, which includes the aforementioned control and auxiliary system; an electric drive body including a drive motor and a reduction mechanism; wherein the control and auxiliary system and the electric drive body are connected via cooling oil pipes and high and low voltage wiring harnesses.

The motor controller system and the auxiliary system are adjacent to each other. This application recognizes that while the electric drive unit in an electric drive assembly can adapt to different vehicle models and their varying installation requirements, the control and auxiliary systems cannot. Therefore, the relevant components in the control and auxiliary systems require continuous structural adjustments to accommodate the electric drive unit. Based on this, this application structurally separates the control and auxiliary systems from the electric drive unit in the electric drive assembly, dividing the control and auxiliary systems into a motor controller system and an auxiliary system.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0027] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. The term "connection," unless otherwise specified, includes both direct and indirect connections.

[0028] In specific embodiments, the modular electric drive control and assistance system is applicable to the electric drive assembly of any type of vehicle. For example, the control and assistance system is applicable to the electric drive assembly of a pure electric vehicle; for example, the control and assistance system is applicable to the electric drive assembly of a range-extended electric vehicle. For ease of explanation, the following description uses the application of the control and assistance system to the electric drive assembly of a pure electric vehicle as an example to illustrate the structure of the control and assistance system.

[0029] In some embodiments, such as Figure 3 As shown, the control and auxiliary system 100 includes a motor controller system 110 and an auxiliary system 120. The motor controller system 110 has a motor controller housing 111, and a motor controller 112 is installed inside the motor controller housing 111.

[0030] Specifically, this application recognizes that different vehicle models and different installation boundaries place completely different structural requirements on the electric drive assembly system 10. The control and auxiliary system 100 needs to be designed according to the specific installation positions of relevant components in the control and auxiliary system 100 based on the different vehicle models and different installation boundaries. This application divides the control and auxiliary system 100 into two parts: a motor controller system 110 and an auxiliary system 120. The motor controller system 110 actively controls the drive motor to work according to the set direction, speed, angle, and response time. The auxiliary system 120 filters and cools the lubricating oil in the electric drive body 200, and also assists in lubricating the components within the electric drive body 200. By making the motor controller system 110 an independent module and the auxiliary system 120 an independent module, the two modules are integrated together and rationally arranged, making them a unified control and auxiliary system module. The motor controller system 110 includes a motor controller housing 111, which forms a cavity for housing and mounting motor controller 112 and related components. The specific structure and dimensions of the motor controller housing 111 are not limited; for example, it can be a cubic structure, or, depending on the shape of a vehicle chassis, it can be an irregular structure. To ensure heat dissipation of the entire motor controller system 110, the motor controller housing 111 can be a closed structure, or it can be a structure with through holes or openings. The motor controller system 110 may also include a controller cooling water pipe 113 for cooling the motor controller 112; details are described below.

[0031] The control and auxiliary system 100 includes an auxiliary system 120, which has an auxiliary system housing 121. A filter system 122, an oil pump system 123, and a first radiator 124 are installed inside the auxiliary system housing 121. The motor controller system 110 is adjacent to the auxiliary system 120.

[0032] Specifically, the auxiliary system 120 is treated as an independent module. The auxiliary system 120 includes an auxiliary system housing 121, which forms a cavity to house components such as the filter system 122, oil pump system 123, and first radiator 124. The specific structure and dimensions of the auxiliary system housing 121 are not limited; for example, it can be a cubic structure. Alternatively, depending on the shape of the chassis, it can be an irregular structure. The auxiliary system housing 121 can be a closed structure, or it can be configured with through holes or openings. The arrangement order and relative position of the filter system 122, oil pump system 123, and first radiator 124 within the auxiliary system housing 121 are not limited and can be determined according to actual conditions. For example, the filter system 122, oil pump system 123, and first radiator 124 can be arranged adjacently; for example, the filter system 122, oil pump system 123, and first radiator 124 can be arranged alternately; for example, the filter system 122, oil pump system 123, and first radiator 124 can be arranged alternately. To minimize space, the motor controller system 110 is adjacent to the auxiliary system 120, integrating the two modules into a single control and auxiliary system module, thereby improving the adaptability of the control and auxiliary system 100 and meeting the installation requirements of different vehicle models.

[0033] The present invention provides a modular electric drive control and auxiliary system, which includes a motor controller system and an auxiliary system. The motor controller system has a motor controller housing, and a motor controller is installed inside the motor controller housing. The auxiliary system has an auxiliary system housing, and a filter system, an oil pump system and a first radiator are installed inside the auxiliary system housing. The motor controller system and the auxiliary system are adjacent to each other. This application recognizes that while the electric drive unit in an electric drive assembly can adapt to different vehicle models and their varying installation requirements, the control and auxiliary systems cannot. Therefore, the relevant components in the control and auxiliary systems require continuous structural adjustments to accommodate the electric drive unit. Based on this, this application structurally separates the control and auxiliary systems from the electric drive unit in the electric drive assembly, dividing the control and auxiliary systems into a motor controller system and an auxiliary system. This allows for modular integration of the relevant components, making the motor controller system a module and the auxiliary system a module. The motor controller system and the auxiliary system are connected to form a unified control and auxiliary system module. After the electric drive unit is installed in any structural form, the control and auxiliary system is installed as a unified module on the vehicle, resulting in more flexible placement, increased adaptability of the control and auxiliary systems to electric drive units with different installation structures, improved versatility of the entire control and auxiliary system, and reduced development time and costs for structural adjustments.

[0034] In some embodiments, such as Figure 3 As shown, the motor controller system 110 and the auxiliary system 120 share the same housing. Specifically, to save space, the motor controller 112, the first radiator 124, the oil pump system 123, and the filter system 122, and other related components are placed together as much as possible, so the motor controller system 110 and the auxiliary system 120 share the same housing. It should be noted that sharing the same housing here includes various situations, which will be described in detail through embodiments. For example, the control and auxiliary system 100 has only one housing, which can be called the motor controller housing 111 or the auxiliary system housing 121, and the motor controller system 110 and the auxiliary system 120 share this housing; for example, the control and auxiliary system 100 has two housings, the motor controller housing 111 only surrounds and accommodates the motor controller 112, and the auxiliary system housing 121 surrounds and accommodates the motor controller housing 111 and the filter system 122, the oil pump system 123, and the first radiator 124, and other related components; for example, as Figure 3 As shown, the control and auxiliary system 100 has two housings. The auxiliary system housing 121 only surrounds and accommodates the filter system 122, the oil pump system 123 and the first radiator 124 and other related components. The motor controller housing 111 surrounds and accommodates the auxiliary system housing 121 and the motor controller 112.

[0035] In some embodiments, such as Figure 3 As shown, the filtration system 122, oil pump system 123, and first radiator 124 are arranged sequentially and adjacently within the auxiliary system housing 121. Specifically, considering the flow path of the lubricating oil while saving space as much as possible, the lubricating oil flows out from the oil inlet 230 of the electric drive body 200. First, the lubricating oil enters the filtration system 122 through the oil inlet 125. After passing through the filtration system 122, the lubricating oil is filtered to remove metallic impurities, improving the cleanliness of the lubricating oil and preventing it from flowing back into the cavity of the electric drive body 200, which could cause wear on gears and other components. The filtration system 122 may include various filtration devices or structures. For example, the filtration system 122 may include a filter element for filtration; or it may include a magnet to attract metallic impurities. After being filtered by the filtration system 122, the lubricating oil flows into the oil pump system 123. The oil pump system 123 includes an oil pump to provide power for the flow of the lubricating oil. To facilitate cooling of the lubricating oil, the oil pump system 123 may also include an oil chamber for cooling. The lubricating oil then flows into the first radiator 124 for cooling, and finally flows out through the oil outlet 126 of the first radiator 124, returning the lubricating oil to the electric drive body 200 to cool and lubricate the components inside the electric drive body 200. Based on the lubricating oil flow path, the filter system 122, the oil pump system 123, and the first radiator 124 are arranged sequentially and adjacent to each other in the auxiliary system housing 121.

[0036] In some embodiments, such as Figure 3As shown, a heat dissipation fin 130 is provided between the motor controller system 110 and the auxiliary system 120. Specifically, considering that the motor controller system 110 and the auxiliary system 120 are integrated into a large module, the motor controller 112 in the motor controller system 110 is prone to heat generation, and the auxiliary system 120 also needs to exchange heat with the lubricating oil, which can easily lead to high temperatures in the control and auxiliary systems 100. To facilitate heat dissipation, a heat dissipation fin 130 can be provided between the motor controller system 110 and the auxiliary system 120. The heat dissipation fin 130 is used for auxiliary heat dissipation. The specific structural dimensions of the heat dissipation fin 130 can be determined according to actual needs. For example, the heat dissipation fin 130 can be rectangular. 130 is located between the motor controller 112 and the filter system 122. The heat dissipation fin 130 separates the two heat-generating components of the motor controller 112 and the filter system 122 to prevent heat radiation and allow the high temperature between the motor controller 112 and the filter system 122 to dissipate quickly. For example, the heat dissipation fin 130 is designed to be curved so that it wraps around the motor controller 112 to assist in the heat dissipation of the motor controller 112. For example, the motor controller housing 111 is made of metal, and the heat dissipation fin 130 can be connected to the motor controller housing 111, so that the heat dissipation is achieved by using the motor controller housing 111 and the heat dissipation fin 130.

[0037] In some embodiments, such as Figure 3 As shown, the motor controller system 110 also includes a controller cooling water pipe 113, which is used to cool the motor controller 112. Specifically, in order to accelerate the heat dissipation of the control and auxiliary system 100, the motor controller system 110 also includes a controller cooling water pipe 113. The configuration of the controller cooling water pipe 113 is not limited. For example, the controller cooling water pipe 113 can pass through the inside of the motor controller 112 to cool the motor controller 112, with cooling water entering from the inlet 115 and hot water for heat exchange exiting from the outlet 116; for example, the controller cooling water pipe 113 can wrap around the outside of the motor controller 112 to cool the motor controller 112; for example, the controller cooling water pipe 113 can both pass through the inside of the motor controller 112 and wrap around the outside of the motor controller 112 to cool the motor controller 112. The path of the controller cooling water pipe 113 is not limited. For example, the controller cooling water pipe 113 can be set in a serpentine shape; for example, the controller cooling water pipe 113 can be set in a U-shape. For example, the controller cooling water pipe 113 can be a single channel, or the controller cooling water pipe 113 can be divided into multiple branches through the main channel for cooling.

[0038] In some embodiments, the oil pump system 123 further includes an oil chamber, and the controller cooling water pipe 113 is adjacent to the oil chamber. The controller cooling water pipe 113 can exchange heat with the lubricating oil in the oil chamber, thereby assisting in cooling the lubricating oil.

[0039] In some embodiments, such as Figure 4 As shown, the motor controller system 110 also includes a second radiator 114, which is connected to the controller cooling water pipe 113 to assist in heat dissipation from the controller cooling water pipe 113. Specifically, considering that integrating the motor controller system 110 and the auxiliary system 120 into a large module will generate high heat, a second radiator 114 can be added to the motor controller system 110 to assist in heat dissipation. The coolant in the controller cooling water pipe 113 flows into the second radiator 114 after passing through the motor controller 112, and the second radiator 114 assists in heat dissipation, reducing the temperature of the coolant so that heat exchange can be better achieved when the coolant is recirculated.

[0040] In some embodiments, this application also provides a modular electric drive assembly system 10, which includes a control and auxiliary system 100 and an electric drive body 200. The electric drive body 200 includes a drive motor and a reduction mechanism. The control and auxiliary system 100 and the electric drive body 200 are connected by a cooling oil pipe 140 and high and low voltage wiring harnesses. Specifically, different vehicle models and different installation requirements dictate different requirements for the electric drive unit 200. In some models, the input shaft 210 and output shaft 220 within the electric drive unit 200 are arranged horizontally; in others, they are arranged vertically. To accommodate the needs of different vehicle models and different installation requirements, the control and auxiliary system 100 and the electric drive unit 200 are modularized. This results in the electric drive assembly system 10 including both a modular control and auxiliary system 100 and a modular electric drive unit 200. After the electric drive unit 200 adapts to different installation requirements, the modular control and auxiliary system 100 can be directly installed on the vehicle, increasing the variety of placement options. For example, ... Figure 5 As shown, the input shaft 210 and output shaft 220 within the electric drive body 200 are arranged horizontally. The control and auxiliary system 100 is connected to the electric drive body 200 via a cooling oil pipe 140 and high and low voltage wiring harnesses. For example, as Figure 6As shown, the input shaft 210 and output shaft 220 within the electric drive body 200 are arranged vertically. The control and auxiliary system 100 is connected to the electric drive body 200 via a cooling oil pipe 140 and high and low voltage wiring harnesses. Thus, the motor controller system 110 controls the drive motor and reducer within the electric drive body 200, and the auxiliary system 120 cools the lubricating oil within the electric drive body 200.

[0041] In some embodiments, such as Figure 5 and Figure 6 As shown, when the vehicle is stationary, at least one oil suction port 230 is located at the bottom of the housing of the electric drive body 200. The filtration system 122 is connected to the oil suction port 230 via the cooling oil pipe 140. Specifically, to ensure that the oil pump system 123 in the auxiliary system 120 can draw oil from the electric drive body 200 and to avoid cavitation, at least one oil suction port 230 is located at the bottom of the housing of the electric drive body 200 when the vehicle is stationary. Lubricating oil flows out from the bottom oil suction port 230 and enters the filtration system 122. Considering that the vehicle may tilt during uphill and downhill driving, and the electric drive assembly system 10 will also tilt accordingly, the oil suction port 230, which is originally located at the bottom of the housing of the electric drive body 200, may not be in the correct position when tilted. At the lowest position in the direction of gravity, other oil suction ports 230 can also be set. The specific positions of other oil suction ports 230 can be determined according to the actual situation. For example, at the maximum tilt angle, find the lowest position of the housing of the electric drive body 200 so that the lubricating oil flows out from the other oil suction ports 230 and enters the filter system 122. At the same time, avoid the phenomenon of suction cavitation. Multiple oil suction ports 230 can be closed as needed. For example, if the sensor determines that the oil suction port 230 is below the surface of the lubricating oil, it will be opened to suck oil; otherwise, it will be closed, thereby avoiding the phenomenon of suction cavitation in the oil pump.

[0042] In some embodiments, this application also provides an automobile, which includes an electric drive assembly system 10, a chassis, and wheels. The chassis has a receiving cavity for accommodating and supporting the electric drive assembly system 10. Multiple wheels are located on both sides of the chassis and connected to the electric drive assembly system 10. Specifically, the electric drive assembly system 10 is mounted on the chassis, and wheels are mounted on both sides of the chassis. The shaft of the drive motor is connected to the main shaft of the reducer, transmitting power to the reducer main shaft. The power is then transferred to the intermediate shaft gear via the main shaft gear on the reducer main shaft. Subsequently, the intermediate shaft gear engages with the differential half-shaft gear, driving the differential half-shaft gear to rotate. Finally, the power is transmitted to the left and right wheels via the left and right half-shafts, thereby realizing power transmission.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
