[0099] In some embodiments of the present application, as shown in Figure 3 the power assembly comprises a second connecting piece 8, the second connecting piece 8 connects one end of the second shell 2 and the first shell 1 in the cavity 100, and the orthographic projection of the second connecting piece 8 in the projection plane partially overlaps the orthographic projection of the second wiring portion 72 in the projection plane. The projection plane is a plane perpendicular to the first direction.

[0100] It can be understood that the second connecting piece 8 connects one end of the second shell 2 and the first shell 1, which is beneficial to the assembly of the first shell 1 and the second shell 2. The orthographic projection of the second connecting piece 8 in the projection plane partially overlaps the orthographic projection of the second wiring portion 72 in the projection plane, which is beneficial to improving the compactness of the power assembly of the present application and reducing the volume of the power assembly of the present application.

[0101] In the embodiments of the present application, the other end of the first shell 1 can have a flange structure, and the second connecting piece 8 can pass through the flange structure of the other end of the first shell 1 from the cavity 100 to form a connection with the second shell 2, so as to realize the connection of one end of the first shell 1 and the second shell 2.

[0105] In some embodiments of the present application, as shown in Figure 3 in the first direction, the second wiring portion 72 is farther away from the opening of the second sub-cavity 202 than the first wiring portion 71.

[0106] It can be understood that, since the normal projection of the second connecting member 8 in the projection plane is partially overlapped with the normal projection of the second wiring portion 72 in the projection plane, and the second connecting member 8 is generally connected with the second shell 2 inside the second shell 2, the second wiring portion 72 extending into the second sub-cavity 202 is likely to cause interference with the lapping of the second connecting member 8 and the second shell 2, and therefore, the second wiring portion 72 is arranged to be farther away from the opening of the second sub-cavity 202 than the first wiring portion 71, which is beneficial to the stable connection of the second connecting member 8 and the second shell 2.

[0107] In some embodiments of the present application, as shown in Figure 3 the distance D2 between the second wiring portion 72 and the opening of the second sub-cavity 202 facing the first shell 1 in the first direction is at least 40 mm.

[0108] It can be understood that, the distance between the communication cavity 203 and the opening of the second sub-cavity 202 facing the first shell 1 is at least 40 mm, which is beneficial to the stable connection of the second connecting member 8 and the second shell 2.

[0109] In embodiments of the present application, the distance D2 between the communication cavity 203 and the opening of the second sub-cavity 202 facing the first shell 1 can be 40 mm, 45 mm, 50 mm or 60 mm, or other values.

[0110] In embodiments of the present application, the thickness of the second sub-cavity 202 is at least 15 mm, and the second connecting member 8 extends into the second shell 2 from the cavity 100 and forms a lapping with the second shell 2, and the length required for forming a stable lapping is 25 mm, and therefore, the distance between the communication cavity 203 and the opening of the second sub-cavity 202 facing the first shell 1 is at least 40 mm.

[0111] Optionally, the converging portion 73 can be connected with the second shell 2 through a third connecting member 11, so that the converging portion 73 forms a sealing surface with the second shell 2, and seals the end of the communication cavity 203 close to the first sub-cavity 201. The length required for the lapping of the second connecting member 8 and the second shell 2 is affected by the wall thickness of the second sub-cavity 202, the length of the second connecting member 8 extending into the second shell 2, and the width of the third connecting member 11, and the above three size parameters are comprehensively considered, and therefore, the length required for the lapping of the second connecting member 8 and the second shell 2 is at least 25 mm.

[0112] In some embodiments of the present application, as shown in Figure 1 the width D1 of the cavity 100 in the first direction is in the range of 70 to 110 mm.

[0113] It can be understood that the above value range is beneficial to the assembling tool to operate the first connecting piece 5 to connect the first shell 1 and the engine 3, and is also beneficial to the power assembly of the application to have a smaller size and to reduce the occupation of the vehicle body space.

[0114] In the embodiment of the application, the distance D1 of the cavity 100 from the engine 3 to the second shell 2 can be 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, or 110mm, or other values in the range of 70mm to 110mm.

[0115] The second aspect of the application provides an automobile comprising the power assembly of the above embodiment.

[0116] It can be understood that, due to the power assembly of the above embodiment, the automobile of the application has the same technical effects as the above embodiment, which will not be described here.

[0117] In some embodiments of the application, as shown in Figure 1 The automobile further comprises a longitudinal beam 9 and a suspension assembly 10, both of which are located on the side of the second shell 2 opposite the first shell 1, and the suspension assembly 10 connects the second shell 2 and the longitudinal beam 9.

[0118] It can be understood that the longitudinal beam 9 can bear the pressure from the power assembly. The suspension assembly 10 can buffer the vibration from the motor 4 and the engine 3. By connecting the second shell 2 and the longitudinal beam 9 through the suspension assembly 10, the vibration transmitted from the motor 4 and the engine 3 to the longitudinal beam 9 is reduced.

[0119] In the application, the terms "first" and "second" are used for descriptive purposes only and cannot be construed as indicating or implying relative importance. The term "a plurality of" refers to two or more, unless otherwise explicitly limited.

[0120] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. The application is intended to cover any variations, uses, or adaptations of the application following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice in the art to which the application pertains. The specification and examples are to be regarded as illustrative only.

[0121] It should be understood that the application is not limited to the precise construction and method described above and illustrated in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the application is limited only by the claims that follow.
