In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention, rather than to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0032] First, see Figure 1 The embodiment of the present application provides a modular assembly of a motor and a controller, which includes a motor assembly, a controller 1, and an end cover assembly 2. The controller 1 is arranged at one end of the motor assembly in its own axial direction, the controller 1 is electrically connected to the motor assembly, the end cover assembly 2 is axially arranged between the motor assembly and the controller 1, one side of the end cover assembly 2 is connected to the motor assembly, and the other side of the end cover assembly 2 is connected to the controller 1, and the controller 1 is located in the orthographic projection of the end cover assembly 2 in the axial direction.

[0033] In some embodiments, one side of the end cover assembly 2 is connected to the motor assembly, and the other side of the end cover assembly 2 is connected to the controller 1. The connection can be optionally detachable. The detachable connection can be detachably connected by fastening with fasteners such as bolts, or can be detachably connected by partially extending one into the other for snap-fitting.

[0034] In some embodiments, the controller 1 is disposed at one end of the motor assembly in its own axial direction, and can be optionally disposed at the non-output end of the motor assembly. Such a configuration can maximally avoid interference between the controller 1 and the output end of the motor assembly during use, thereby affecting the normal operation of the modular assembly of the motor and the controller. Of course, in other embodiments, the controller 1 can also be disposed at one end of the motor assembly in its own axial direction, and can be optionally disposed at the output end of the motor assembly, so as to avoid interference between the controller 1 and the output end of the motor assembly during use.

[0035] An embodiment of the present application provides a modular assembly of a motor and a controller and a vehicle, wherein the modular assembly of the motor and the controller includes a motor assembly, a controller 1 and an end cover assembly 2. The controller 1 is arranged at one end of the motor assembly in its own axial direction, which reduces the radial size of the modular assembly of the motor and the controller in the motor assembly. In addition, the end cover assembly 2 is axially placed between the motor assembly and the controller 1 and is connected to the motor assembly on one side and to the controller 1 on the other side. The end cover assembly 2 serves as both the end cover of the controller 1 and the rear end cover of the motor assembly, thereby realizing the sharing of the housing, which not only reduces the overall size of the modular assembly of the motor and the controller, but also reduces the cost. In addition, the controller 1 is located within the orthographic projection of the end cover assembly 2 in the axial direction, and the spatial arrangement is reasonable, so that the axial size of the modular assembly of the motor and the controller increases less, thereby making the modular assembly of the motor and the controller occupy less space and have a higher degree of integration.

[0036] It should be noted that the modular assembly of the motor and controller provided in the embodiment of the present application can be applied not only in the field of new energy vehicles, but also in other technical fields. In other words, as long as it is necessary to drive the device to move, the modular assembly of the motor and controller provided in the embodiment of the present application can be used.

[0037] In some embodiments, the controller 1 includes a shell 11 and electronic components 12 . The shell 11 has a first accommodating cavity 111 . The electronic components 12 are disposed in the first accommodating cavity 111 and are electrically connected to the motor assembly. The shell 11 is connected to the end cover assembly 2 .

[0038] The shell 11 and the end cap assembly 2 are matched in size, and such a setting facilitates the connection of the shell 11 and the end cap assembly 2. The electronic component 12 is arranged in the first accommodating cavity 111. It can be understood that the electronic component 12 is arranged in the first accommodating cavity 111 and is directly connected to the shell 11 so that it is fixed in the first accommodating cavity 111. The connection can be selected as a detachable connection, for example, it can be detachably connected by fastening with fasteners such as bolts, or it can be detachably connected by partially extending one into the other for snap-fitting. Of course, the electronic component 12 can also be fixed in the first accommodating cavity 111 by the shell 11 and the end cap assembly 2.

[0039] The shell 11 is connected to the end cover assembly 2, which can be optionally detachably connected. The detachable connection can be detachably connected by fastening with fasteners such as bolts, or by partially extending one into the other for snap-fitting.

[0040] In some embodiments, a first connecting hole may be provided on the shell 11, and a second connecting hole may be provided on the end cover assembly 2. The shell 11 is connected to the end cover assembly 2 by fasteners passing through the first connecting hole and the second connecting hole. Such a setting can facilitate the connection between the shell 11 and the end cover assembly 2, and at the same time, it is also convenient for the inspection, maintenance and replacement of electronic components.

[0041] A modular assembly of a motor and a controller provided in an embodiment of the present application, by providing a first accommodating cavity 111 on a shell 11, and disposing an electronic component 12 in the first accommodating cavity 111, can not only achieve the installation and fixation of the electronic component 12, but also prevent dust from falling on the electronic component 12, thereby increasing the service life of the electronic component 12.

The modular assembly of the motor and controller provided in one embodiment of the present application arranges the capacitor component 121 and the water cooling component 122 side by side between the housing 11 body and the circuit board component 123, and the spatial arrangement is reasonable, so that the axial dimension of the modular assembly of the motor and controller increases less, thereby making the modular assembly of the motor and controller occupy less space and have a higher degree of integration.

The low-voltage terminal 1231 is electrically connected to the vehicle controller. This arrangement reduces the use of internal wiring harnesses and connectors of the controller 1, and further reduces the modular assembly cost of the motor and the controller.

[0045] In some embodiments, the circuit board assembly 123 further includes a heat dissipation module 1232 to further improve the heat dissipation effect of the modular assembly of the motor and the controller.

[0046] See also Figure 1 The housing 11 may optionally adopt an integral casting structure to further increase the stability and heat dissipation safety of the modular assembly of the motor and controller.

[0047] In some embodiments, see Figure 2 and Figure 3 The water channel 112 includes a water inlet 1121, a water outlet 1122 and a water channel cavity 1123. The water inlet 1121, the water outlet 1122 and the water channel cavity 1123 are all connected, and the water inlet 1121 and the water outlet 1122 are both arranged axially toward the motor assembly.

[0048] A modular assembly of a motor and a controller provided in an embodiment of the present application avoids the modular assembly of the motor and the controller from occupying external space as a whole by arranging the water inlet 1121 and the water outlet 1122 axially toward the motor assembly, thereby further making the modular assembly of the motor and the controller occupy less space and more integrated.
