[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0034] As mentioned in the background section, a range extender generally refers to an electric vehicle component that can provide additional electrical energy, thereby increasing the driving range of an electric vehicle. It is usually understood as a combination of an engine and a generator. Existing cooling oil pumps can cool the generator rotor and are usually installed on the generator block, but they have the problems of cumbersome installation process and are not conducive to the compact design of the range extender.
[0035] Please refer to Figure 1 The integrated end cap 100, range extender, and vehicle provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.
[0036] In a first aspect, an embodiment of the present invention provides an integrated end cap 100, which is applied to a range extender. The integrated end cap 100 includes an end cap body 110 and a cooling oil passage 120.
[0037] The end cap body 110 has a cooling oil pump mounting chamber 111 and an oil cooler mounting interface 112, and a cooling oil passage 120 is formed between the cooling oil pump mounting chamber 111 and the oil cooler mounting interface 112.
[0038] During assembly, the integrated end cap 100 can be used to install the cooling oil pump through the cooling oil pump mounting chamber 111 and the oil cooler through the oil cooler mounting interface 112. The oil is transported by the cooling oil passage 120, which facilitates the installation of the cooling oil pump, simplifies the installation process, and is conducive to the compact modification of the range extender.
[0039] It is worth noting that, for the sake of compactness and weight reduction, range extenders usually integrate the engine block and generator block into a single integrated block. To facilitate the installation of the generator assembly, the end of the integrated block closest to the generator assembly is left open. The integrated end cap 100 is connected to the open end of the integrated block, and together with the integrated block, they achieve sealed protection for the internal engine and generator assemblies.
[0040] In this embodiment, the cooling oil pump mounting chamber 111 is located at the center of the integrated end cover 100, and the oil cooler mounting interface 112 is located at the bottom of the integrated end cover 100 on the side away from the cylinder block, thereby fixing the positions of the installed cooling oil pump and oil cooler. Of course, in other embodiments of this utility model, provided that the cooling effect is satisfied, the cooling oil pump mounting chamber 111 and the oil cooler mounting interface 112 can also be set in other positions, and the specific setting positions of the two are not limited.
[0041] Please refer to Figure 1 To facilitate the connection and fixing of the controller, a controller support platform 113 is formed on the side of the end cap body 110 away from the cylinder body. Furthermore, at least three controller mounting interfaces 114 are formed on the controller support platform 113, and the at least three controller mounting interfaces 114 are arranged in an enclosing manner along the controller support platform 113.
[0042] In this embodiment, the controller control platform is in the form of a ring plane and is used to contact the end face of the controller. The number of controller mounting interfaces 114 is more than ten, and the more than ten controller mounting interfaces 114 are arranged relatively evenly around the controller support platform 113.
[0043] In this embodiment, the cross-section of the controller mounting interface 114 is circular. In other embodiments of this utility model, the controller mounting interface 114 can also be triangular, rectangular, fan-shaped, elliptical, or other shapes. There is no limitation on its specific cross-sectional shape.
[0044] It should be noted that the enclosure setting specifically means that the connection formed by all the controller mounting interfaces 114 along the arrangement direction is a closed shape.
[0045] Please refer to Figure 1 To avoid interference between the controller installation and other oil passages or components, the controller support platform 113 can be made to protrude from the cooling oil passage 120, the cooling oil pump installation chamber 111, and the oil cooler installation interface 112.
[0046] This can be understood as the distance between the plane of the controller support platform 113 and the cylinder end face being greater than the distance between the cooling oil passage 120 and the cylinder end face, the distance between the cooling oil pump mounting chamber 111 and the cylinder end face, and the distance between the oil cooler mounting interface 112 and the cylinder end face.
[0047] It is worth noting that the cooling oil pump mounting chamber 111 is located on the inner side of the annular ring of the controller support platform 113, and the oil cooler mounting interface 112 is located on the outer side of the annular ring of the controller support platform 113.
[0048] Furthermore, since the oil cooler is used to cool the oil, and the oil cooler itself needs to use cooling water to achieve the purpose of cooling the oil, it is necessary to set up a corresponding water channel to supply water to the oil cooler.
[0049] The integrated end cap 100 also includes an oil cooler cooling water channel 130. In order to improve the efficiency of cooling water supply, the oil cooler cooling water channel 130 can be arranged adjacent to the oil cooler mounting interface 112 so that cooling water can flow into the oil cooler quickly to cool the oil.
[0050] In this embodiment, the oil cooler cooling water channel 130 is inclined and located on one side of the oil cooler mounting interface 112; of course, in other embodiments of this utility model, the oil cooler cooling water channel 130 can also be arranged in a horizontal or vertical direction, and there is no limitation on the specific setting orientation and arrangement position of the device.
[0051] Please refer to Figure 1 In order to monitor the temperature of the rotor in the range extender in real time, a temperature sensor mounting interface 115 can be formed on the end cover body 110, and the cooling oil pump mounting chamber 111 is close to the temperature sensor mounting interface 115 relative to the oil cooler mounting interface 112.
[0052] In this embodiment, there is one temperature sensor mounting interface 115. Of course, in other embodiments of this utility model, in order to improve the accuracy of temperature detection, the number of temperature sensor mounting interfaces 115 can be two, three, five, etc., so as to facilitate the installation of temperature sensors in different positions and thus realize comprehensive monitoring of rotor temperature.
[0053] It is worth noting that the temperature sensor mounting interface 115 is located on the inner side of the annular ring of the controller support platform 113.
[0054] Please refer to Figure 1 In order to facilitate the connection of the three-phase terminals and the DC bus plug, a three-phase terminal mounting interface 116 can be formed on the end cover body 110, and a DC bus plug interface 117 can be formed on the end cover body 110.
[0055] Meanwhile, in order to maximize space utilization and reduce the possibility of interference between different components and tangling of different wire harnesses, the three-phase terminal mounting interface 116 and the DC bus plug interface 117 can be located on both sides of the cooling oil pump mounting chamber 111.
[0056] Furthermore, the three-phase terminal mounting interface 116 and the DC bus plug interface 117 can be set higher than the oil cooler mounting interface 112, and the DC bus plug interface 117 and the temperature sensor mounting interface 115 are located on the same side of the cooling oil pump mounting chamber 111.
[0057] It is worth noting that the three-phase terminal mounting interface 116 and the DC bus plug interface 117 are both located on the inner side of the annular ring of the controller support platform 113.
[0058] Secondly, embodiments of this utility model also provide a range extender for use in automobiles. The range extender includes an integrated end cap 100, an integrated cylinder block, an engine assembly, a generator assembly, and an oil pan. The oil pan is connected to the lower side of the integrated cylinder block. The integrated cylinder block has an integrally formed engine chamber and a generator chamber for mounting the engine assembly and generator assembly, respectively. One end of the integrated cylinder block near the generator chamber is open. The end cap body 110 is connected to the open end of the integrated cylinder block and cooperates with the integrated cylinder block to shield and protect the engine assembly and generator assembly within the integrated cylinder block. This makes the overall range extender lighter and more compact, which is beneficial for improving the vehicle's range. The range extender includes the integrated end cap 100, which possesses all the functions of the integrated end cap 100.
[0059] Thirdly, embodiments of this utility model also provide an automobile, including a range extender, a power battery system, a power drive system, a vehicle control system, and a vehicle body. Each system and the range extender are installed in different locations on the vehicle body and work together to achieve the driving force for the vehicle body. Specifically, this automobile can be a sedan, SUV, van, truck, or bus; the specific type of automobile is not limited. This automobile includes a range extender and possesses all the functions of a range extender.
[0060] In summary, the integrated end cap, range extender, and automobile provided by the embodiments of this utility model have at least the following advantages:
[0061] (1) The integrated end cap 100 can install the cooling oil pump through the cooling oil pump installation chamber 111 and the oil cooler through the oil cooler installation interface 112. The oil is transmitted by the cooling oil passage 120, which facilitates the installation of the cooling oil pump, simplifies the installation process, and is conducive to the compact modification of the range extender.
[0062] (2) The integrated end cap 100 can form a controller support platform 113 on the side away from the cylinder block, and the controller can be installed and fixed by forming at least three controller mounting interfaces 114 on the controller support platform 113; and the controller support platform 113 protrudes from the cooling oil passage 120, the cooling oil pump mounting chamber 111 and the oil cooler mounting interface 112, thereby avoiding interference between the installation of the controller and other oil passages or components.
[0063] (3) The integrated end cap 100 is provided with an oil cooler cooling water channel 130 at the adjacent position of the oil cooler installation interface 112, so that the path of the oil cooler cooling water channel 130 is not too long, so that the cooling water can flow into the oil cooler quickly, thereby ensuring the supply efficiency of cooling water and ensuring the cooling effect of the oil cooler on the oil.
[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
