[0001] This utility model belongs to the field of motor sound insulation technology. Specifically, this utility model relates to a novel motor insulation structure. Background Technology

[0002] In recent years, my country's new energy electric vehicle industry has developed rapidly, and the comfort of new energy electric vehicles has become a goal pursued by the automotive industry. The vibration and... Noise can affect the comfort of a car, but the motors in existing electric vehicles are noisy, so a motor enclosure structure is needed to reduce the noise.

[0003] Chinese Patent (Publication No.: 110774989A) discloses a motor enclosure structure integrating sound absorption and impact protection. It includes a first substrate and a second substrate. Several protrusions are evenly distributed on one side of both substrates, forming a semi-cavity. Several through holes are formed on the bottom surface of the semi-cavity on the first substrate. The protrusions of the second substrate are fixed to the corresponding protrusions on the first substrate, thus forming several cavity structures composed of two semi-cavities between the two substrates. These cavity structures and their corresponding through holes form Helmholtz resonant cavities. However, the motor using this integrated sound absorption and impact protection structure still exhibits significant noise. Utility Model Content

[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0015] like Figure 1 , Figure 2 , Figure 5 ,and Figure 6 As shown, a novel motor enclosure structure includes a motor 1, on which a motor enclosure mechanism is provided. The motor enclosure mechanism encloses the motor, tightly covering the motor 1, forming a relatively enclosed space, which creates conditions for blocking and absorbing noise from the motor 1.

[0016] like Figure 1As shown, the motor enclosure mechanism includes an upper motor enclosure 2 and a lower motor enclosure 3, which enclose the motor 1. The upper and lower motor enclosures cooperate with each other to tightly enclose the motor 1. The upper and lower motor enclosures form the inner and outer layers, respectively. The outer layer of the upper and lower motor enclosures is fabricated using a molded, flat-lay method, while the inner layer is foamed based on the flat-lay outer layer. The foaming boundary of the inner layer is determined by the solid portion of the outer shell after molding. The foaming thickness of the inner layer is adjusted according to the enveloping shape of the motor 1 assembly.

[0017] like Figure 3 As shown, the newly manufactured motor casing 2 requires an outer layer along... Figure 3 The four corners of the square planes A, B, C, D, and E are cut but not completely separated. The cut parts are glued together with Velcro. They are then used after cutting.

[0018] like Figure 4 The newly manufactured motor casing shown has 3 edges. Figure 4 Cut at points F, I, J, and K, but not completely. Secure the cut sections with Velcro. Use after cutting.

[0019] The motor housing 2 includes a ninth connecting shell 201. A first connecting shell 202, a second connecting shell 203, a third connecting shell 204, and a fourth connecting shell 205 are connected to the four sides of the ninth connecting shell 201. The first connecting shell 202 is directly connected to the upper housing of the motor 1. It serves as a key component, covering the upper part of the motor 1 and preventing noise from the upper side of the motor 1 from propagating outwards. The first connecting shell 202, the second connecting shell 203, the third connecting shell 204, and the fourth connecting shell 205 are connected to the ninth connecting shell 201, tightly fitting the sides of the motor 1 to reduce noise transmission from the sides.

[0020] like Figure 2 As shown, the lower housing 3 of the motor includes a tenth connecting housing 301. A fifth connecting housing 302, a sixth connecting housing 303, a seventh connecting housing 304, and an eighth connecting housing 305 are respectively connected to the four sides of the tenth connecting housing 301. The tenth connecting housing 301 is connected to the lower housing of the motor 1, covering the lower part of the motor 1, and is an important component for blocking noise transmission from the lower side of the motor 1. The fifth connecting housing 302, the sixth connecting housing 303, the seventh connecting housing 304, and the eighth connecting housing 305 are respectively connected to the four sides of the motor 1, tightly fitting the sides of the motor 1 to reduce noise transmission from the sides.

[0021] The first connecting shell 202 has a first groove 206 that mates with the motor 1. The first groove 206 has a circular structure and a square structure, which can better adapt to the shape of the motor 1 and enhance the tightness of the connection. The second connecting shell 203 has a second through hole 207 that mates with the motor 1, which can better adapt to the shape of the motor 1 and enhance the tightness of the connection. The third connecting shell 204 has a third through hole 208 that mates with the oil inlet pipe of the motor 1. The third through hole 208 allows the oil inlet pipe to connect to the motor 1, which can better adapt to the shape of the motor 1 and enhance the tightness of the connection. The fourth connecting shell 205 has a fourth through hole 209 that matches the motor 1. The fourth through hole 209 can better adapt to the shape of the motor 1 and enhance the tightness of the connection.

[0022] The first connecting shell 202 is connected to the second connecting shell 203 and the fourth connecting shell 205 via Velcro 4, and the third connecting shell 204 is also connected to the second connecting shell 203 and the fourth connecting shell 205 via Velcro 4. Velcro 4 allows for quick and convenient connection and disassembly. When installing the motor 1 enclosure mechanism, the first connecting shell 202 can be quickly combined with the second connecting shell 203, the third connecting shell 204, and the fourth connecting shell 205 to form a complete enclosure structure; when maintenance, repair, or replacement of parts is required for the motor 1, the first connecting shell 202 can be easily separated from the second connecting shell 203, the third connecting shell 204, and the fourth connecting shell 205.

[0023] The tenth connecting shell 301 has a second groove 306 that mates with the motor 1. The fifth connecting shell 302 has a fifth through hole 307 that mates with the motor 1. The seventh connecting shell 304 has a threaded hole 308, which is connected to the motor 1 by bolts. The fifth through hole 307 and the second groove 306 can better fit the shape of the motor 1, enhancing the tightness of the connection. The threaded hole 308 improves the convenience and stability during installation. The fifth connecting shell 302 is connected to the sixth connecting shell 303 and the eighth connecting shell 305 by Velcro 4, and the seventh connecting shell 304 is also connected to the sixth connecting shell 303 and the eighth connecting shell 305 by Velcro 4. When installing the motor 1 covering mechanism, the Velcro 4 can quickly combine the fifth connecting shell 302 with the sixth connecting shell 303, the seventh connecting shell 304, and the eighth connecting shell 305 to form a complete covering structure; when maintenance, repair, or replacement of parts is required for the motor 1, the fifth connecting shell 302 can be easily separated from the sixth connecting shell 303, the seventh connecting shell 304, and the eighth connecting shell 305.

[0024] Both the upper motor housing 2 and the lower motor housing 3 are made of one-piece EVA. The one-piece EVA construction of the upper motor housing 2 improves overall sealing and further enhances noise reduction.
