The at least two housings include a first housing 101 and a second housing 121. A first sealing portion 103 is provided at the end of the first direction D1 of the first housing 101. The first sealing portion 103 extends along the second direction D2. The first direction D1 is perpendicular to the second direction D2. The second housing 121 and the first housing 101 are opposite and connected in the second direction D2. A second sealing portion 123 is provided at the end of the first direction D1 of the second housing 121. The second sealing portion 123 extends along the second direction D2. The second sealing portion 123 and the first sealing portion 103 are located at the ends of the second housing 121 and the first housing 101 close to each other. That is, the second sealing portion 123 is located at the end of the second housing 121 close to the first housing 101 in the second direction D2. The first sealing portion 103 is located at the end of the first housing 101 close to the second housing 121 in the second direction D2. The cover 151 is connected to the same side of the first housing 101 and the second housing 121 in the first direction D1. The cover 151 includes a third sealing portion 152. Among them, the first sealing portion 103 and the second sealing portion 123 include a groove 104 or a protrusion 152d. The third sealing portion 152 includes a protrusion 152d or a groove 104. That is, if the first sealing portion 103 and the second sealing portion 123 include a groove 104, the third sealing portion 152 includes a protrusion 152d; if the first sealing portion 103 and the second sealing portion 123 include a protrusion 152d, the third sealing portion 152 includes a groove 104. The protrusion 152d is adapted to be inserted into the groove 104. The first sealing member 161 is connected between the first sealing portion 103 and the third sealing portion 152 and between the second sealing portion 123 and the third sealing portion 152. That is, the first seal 161 is located between the aforementioned groove 104 and the protrusion 152d. The first seal 161 may include a first seal layer 161a and a second seal layer 161b. The first seal layer 161a and the second seal layer 161b are respectively arranged on opposite sides of the protrusion 152d along the third direction D3. The third direction D3 is perpendicular to the first direction D1 and the second direction D2. That is, the first seal layer 161a is located in the gap between the one side surface of the protrusion 152d and the one side groove wall of the groove 104 in the third direction D3. Correspondingly, the second seal layer 161b is located in the gap between the other side surface of the protrusion 152d and the other side groove wall of the groove 104 in the third direction D3. The third direction D3 is perpendicular to the first direction D1 and the second direction D2. Among them, the first housing 101 is the housing of the first motor 100. The second housing 121 is the housing of the second motor 120. The cover 151 is at least a part of the housing of the motor controller 150.

[0095] According to the motor assembly of the embodiment of the utility model, at the connection between the first housing 101, the second housing 121 and the cover 151, the first sealing member 161 is arranged between the first sealing portion 103 of the first housing 101 and the third sealing portion 152 of the cover 151, and between the second sealing portion 123 of the second housing 121 and the third sealing portion 152 of the cover 151. Specifically, the first sealing layer 161a and the second sealing layer 161b of the first sealing member 161 are respectively arranged on opposite sides of the protrusion 152d along the third direction D3, thereby increasing the sealing area at the connection between the first housing 101 and the second housing 121 and the cover 151, thereby helping to improve the sealing performance between the first housing 101 and the second housing 121 and the cover 151. Therefore, when the embodiments of the utility model are applied to the connection between the motor controller and the adjacent first housing 101 and second housing 121, it can solve the problem of "unreliable sealing because the connection between the electric control housing and the housing 101 and the connection between the adjacent housings 101 are not sealed at the same time".

[0096] The motor assembly of the present utility model will be further described below by taking the embodiment of the assembly connection of the first housing 101, the second housing 121 and the cover 151 as an example. In the following embodiment, the structure of the first housing 101 is the same as the structure of the second housing 121. In addition, the first sealing portion 103 and the second sealing portion 123 include or are configured as a groove 104, and the third sealing portion 152 includes or is configured as a protrusion 152d.

[0097] For example, the first sealing member 161 may be a sealant. During the production process, a liquid or semi-liquid sealant is applied to the groove 104, and when the protrusion is inserted into the groove 104, the sealant flows and is distributed between the groove wall of the groove 104 and the surface of the protrusion opposite to the third direction D3, and finally, the sealant solidifies and maintains the corresponding shape.

[0098] Optionally, the first sealing member 161 may be made of a sealing material with good fluidity such as 988 molding glue.

[0099] Optionally, the first sealing member 161 may be a sealing structure made of a metal-clad gasket or other preformed materials.

[0100] See also Fig.12For example, the first sealing portion 103 may include a bottom surface 103a, a first groove side surface 103b, and a second groove side surface 103c. The first groove side surface 103b and the second groove side surface 103c are arranged oppositely along the third direction D3. The bottom surface 103a is connected to the first groove side surface 103b and the second groove side surface 103c to enclose the groove 104. The protrusion 152d may include a top surface 152a, a first protrusion side surface 152b, and a second protrusion side surface 152c. The first protrusion side surface 152b and the second protrusion side surface 152c are arranged oppositely along the third direction D3. The top surface 152a is connected to the first protrusion side surface 152b and the second protrusion side surface 152c to form the protrusion 152d. In the state where the protrusion 152d is inserted into the groove 104, the first sealing layer 161a of the first sealing member 161 is arranged between the first groove side surface 103b and the first protrusion side surface 152b. The second sealing layer 161b of the first sealing member 161 is disposed between the second groove side 103c and the second protrusion side 152c. Thus, the first sealing layer 161a and the second sealing layer 161b of the first sealing member 161 form a seal between the protrusion 152d and the groove 104, thereby reliably improving the sealing performance.

[0101] Optionally, the first groove side surface 103b and the second groove side surface 103c may each substantially extend along the first direction D1. In the example where the first groove side surface 103b and the second groove side surface 103c are each plane, the first groove side surface 103b and the second groove side surface 103c may each be parallel to or nearly parallel to the first direction D1, and the first groove side surface 103b and the second groove side surface 103c may each be perpendicular to or nearly perpendicular to the third direction D3. Taking the bottom surface 103a as a plane as an example, the bottom surface 103a may be perpendicular to or nearly perpendicular to the first direction D1.

[0102] Optionally, the first convex side surface 152b and the second convex side surface 152c may each substantially extend along the first direction D1. In the example where the first convex side surface 152b and the second convex side surface 152c are each plane, the first convex side surface 152b and the second convex side surface 152c may each be parallel to or nearly parallel to the first direction D1, and the first convex side surface 152b and the second convex side surface 152c may each be perpendicular to or nearly perpendicular to the third direction D3. Taking the top surface 152a as a plane as an example, the top surface 152a may be perpendicular to or nearly perpendicular to the first direction D1.

[0103] Optionally, any one of the bottom surface 103a, the first groove side 103b, the second groove side 103c, the top surface 152a, the first convex side 152b and the second convex side 152c can be a plane, a curved surface, a special-shaped surface and any combination thereof, other forms of surfaces, etc.

[0104] In this embodiment, the connection between the bottom surface 103a and the first groove side surface 103b and the connection between the bottom surface 103a and the second groove side surface 103c can adopt a smooth transition structure such as chamfering or rounding. It can be understood that the connection between the bottom surface 103a and the first groove side surface 103b and the connection between the bottom surface 103a and the second groove side surface 103c can also be a right angle, acute angle, obtuse angle or other angle structure.

[0105] In this embodiment, the connection between the top surface 152a and the first convex side surface 152b and the connection between the top surface 152a and the second convex side surface 152c can adopt a smooth transition structure such as chamfering or rounding. It can be understood that the connection between the top surface 152a and the first convex side surface 152b and the connection between the top surface 152a and the second convex side surface 152c can also be a right angle, acute angle, obtuse angle or other angle structure.

[0106] See also Fig.12 In addition, the first sealing member 161 may further include a third sealing layer 161c. The third sealing layer 161c is disposed between the bottom surface 103a and the top surface 152a. This can further increase the contact area between the first sealing member 161 and the first sealing portion 103 and the third sealing portion 152, thereby further improving the sealing performance.

[0107] Optionally, when a sealing structure different from the first sealing member 161 is used between the first mounting surface 105 of the first housing 101 and the second mounting surface 153 of the cover 151 to achieve sealing, the third sealing layer 161c can be replaced by the other sealing structure. Similarly, the sealing structure and the connection structure between the second housing 121 and the cover 151 can be implemented with reference to the sealing structure and the connection structure between the first housing 101 and the cover 151.

[0108] Furthermore, the first sealing layer 161a, the third sealing layer 161c and the second sealing layer 161b are connected in sequence, which can improve the continuity of the first sealing member 161 between the first sealing portion 103 and the third sealing portion 152, thereby further improving the sealing effect.

[0109] See also Figures 2 to 5 , Figure 8 , Fig. 9 as well as Fig.12For example, the first housing 101 may include a first mounting surface 105 and a first group of partial bosses 106. The first mounting surface 105 here may be a portion of an end surface of the first housing 101 along the first direction D1, and in particular refers to the edge of the end surface. The first mounting surface 105 here may be a circle of surfaces arranged continuously. The partial bosses 106 protrude from the first mounting surface 105 along the second direction D2. The first group of partial bosses 106 may include two partial bosses 106 arranged at intervals in the third direction D3. A groove 104 is formed between the two partial bosses 106. The first sealing portion 103 is configured as the groove 104. The surfaces of the two partial bosses 106 facing each other can be understood as the first groove side 103b and the second groove side 103c mentioned above. The part of the first mounting surface 105 located between the two partial bosses 106 can be understood as the bottom surface 103a mentioned above.

[0110] Accordingly, the cover body 151 may include a second mounting surface 153 and a first group of partial grooves 154. The second mounting surface 153 is directly or indirectly connected to the first mounting surface 105. The partial groove 154 is recessed relative to the second mounting surface 153 along the second direction D2. The first group of partial grooves 154 may include two partial grooves 154 spaced apart in the third direction D3. A protrusion 152d is formed between the two partial grooves 154.

[0111] By such arrangement, the first seal 161 only needs to be arranged within the range where the local boss 106 and the local groove 154 are connected, which is beneficial to improving the sealing of the connection between the adjacent first housing 101 and the cover 151, saving material cost and processing cost, and also helping to simplify the structure. Moreover, it is also beneficial to facilitate the positioning of the housing and the housing 101 through the cooperation of the local boss 106 and the local groove 154. Furthermore, before the first seal 161 is solidified at the connection between the groove 104 and the protrusion, the cooperation between the local groove 154 and the local boss 106 can also limit the range of the first seal 161 flowing in the second direction D2 and the third direction D3, so that it is more beneficial for the first seal 161 to be fully and evenly distributed at the connection between the groove 104 and the protrusion, which is beneficial to saving the amount of glue applied to the first seal 161 and ensuring the neatness of the connection between the groove 104 and the protrusion.

[0112] Optionally, the first housing 101 may include at least two groups of local bosses 106. The at least two groups of local bosses 106 may include a first group of local bosses 106 and a second group of local bosses 106. The first group of local bosses 106 and the second group of local bosses 106 are arranged at intervals in the third direction D3. For example, the first group of local bosses 106 and the second group of local bosses 106 are respectively located at both ends of the third direction D3 of the first housing 101. The cover 151 may include at least two groups of local grooves 154. The at least two groups of local grooves 154 may include a first group of local grooves 154 and a second group of local grooves 154. The first group of local grooves 154 and the second group of local grooves 154 are arranged at intervals in the third direction D3. The first group of local grooves 154 and the second group of local grooves 154 are each arranged corresponding to the first group of local bosses 106 and the second group of local bosses 106. For example, the first group of local grooves 154 and the second group of local grooves 154 are each located at both ends of the third direction D3 of the cover 151.

[0113] Here, by setting at least two groups of local bosses 106 at both ends of the third direction D3 of the housing 101 and correspondingly setting at least two groups of local grooves 154 on the cover body 151 to cooperate therewith, a more comprehensive seal can be achieved between the first housing 101 and the cover body 151, thereby ensuring the reliability of the seal.

[0114] See also Figures 1 to 5 , Figure 7 as well as Figure 8 For example, the first housing 101 and the second housing 121 may each include a connecting ear 107 protruding along the third direction D3. The connecting ear 107 may include a first connecting hole 107a extending along the second direction D2. The first connecting hole 107a is used to pass a fastening assembly. The connecting ear 107 located in the first housing 101 and the connecting ear 107 located in the second housing 121 are arranged relatively in the second direction D2. The connecting ear 107 located in the first housing 101 and the connecting ear 107 located in the second housing 121 are suitable for connecting a fastening assembly to fasten the first housing 101 to the second housing 121. Optionally, the fastening assembly may include parts such as bolts and nuts.

[0115] See also Figure 2 , Figures 4 to 8 , Fig.10 as well as Fig.11For example, at least one of the first housing 101 and the second housing 121 may include an insertion portion 108. The insertion portion 108 may include a first hole portion 108a and a second hole portion 108b. The first hole portion 108a extends along the second direction D2. The second hole portion 108b is located at an end of the housing 101 away from the first sealing portion 103 in the first direction D1. The second hole portion 108b extends along the first direction D1. The second hole portion 108b is connected to the first hole portion 108a. At least the other of the first housing 101 and the second housing 121 may include a connecting boss 111. The connecting boss 111 is plugged into the first hole portion 108a. The motor assembly may include a fastener 172. The fastener 172 is fastened to the first housing 101 and the second housing 121 at the second hole portion 108b. Here, by cooperating between the insertion portion 108 and the connecting boss 111 and fastening the connecting boss 111 and the housing 101 with the fastener 172 , the fastening connection structure of the two housings 101 can be increased, thereby improving the stability of the connection structure of the two housings 101 .

[0116] Optionally, the first housing 101 and the second housing 121 are each provided with an inserting portion 108 and a connecting boss 111 .

[0117] Continue reading Figure 2 , Figures 4 to 8 , Fig.10 as well as Fig.11For example, the first housing 101 and the second housing 121 each have an axial end face 102 facing each other in the second direction D2. The connecting boss 111 protrudes from the axial end face 102. The connecting boss 111 includes a plug hole 111a that is arranged through the first direction D1. The hole wall of the plug hole 111a in the second direction D2 away from the axial end face 102 is formed with a first guide surface 111b. The distance between the first guide surface 111b and the axial end face 102 in the second direction D2 increases in the first direction D1 away from the first sealing portion 103. The motor assembly may include a connector 171. The connector 171 is adapted to be inserted in the plug hole 111a. The connector 171 includes a second guide surface 171a adapted to be attached to the first guide surface 111b. The fastener 172 is fastened to the housing where the connector 171 and the insertion portion 108 are located. The housing where the insertion portion 108 is located here is the first housing 101 or the second housing 121. In the process of the fastener 172 fastening the plug connector 171 to the housing where the insertion portion 108 is located, due to the cooperation of the first guide surface 111b and the second guide surface 171a, a force will be applied to the housing where the connecting boss 111 is located in the second direction D2 to approach the housing where the insertion portion 108 is located, and this force will increase step by step as the insertion depth of the plug connector 171 in the plug hole 111a increases. In this process, due to the cooperation of the first guide surface 111b and the second guide surface 171a, the housing where the insertion portion 108 is located will also be subjected to a force transmitted through the fastener 172 to approach the housing where the connecting boss 111 is located, and this force will increase step by step as the insertion depth of the plug connector 171 in the plug hole 111a increases. After the connector 171 is fastened to the housing where the insertion portion 108 is located, the connection between the first housing 101 and the second housing 121 will be more stable. And because the force in the second direction D2 is always maintained between the first guide surface 111b and the second guide surface 171a, the axial end surface 102 of the first housing 101 and the axial end surface 102 of the second housing 121 always maintain a pre-tightening force close to each other, which is conducive to ensuring the stability of the seal between the axial end surface 102 of the first housing 101 and the axial end surface 102 of the second housing 121.

[0118] See also Figure 2 , Figure 5 , Figure 6 ,as well as Fig.10 Optionally, the first guide surface 111b is inclined to the third direction D3. The second guide surface 171a is inclined to the third direction D3. And the inclination direction of the second guide surface 171a is the same as the inclination direction of the first guide surface 111b. That is, the first guide surface 111b and the second guide surface 171a are both inclined surfaces inclined to the third direction D3. Compared with curved surfaces or other special-shaped surfaces, inclined surfaces are easier to manufacture, which helps to reduce the complexity of the structure and the difficulty of processing.

[0119] See also Figure 2 , Figure 7 , Figure 8 , Fig.10 as well as Fig.11 For example, the first housing 101 may include a first positioning portion 101b. The first positioning portion 101b is correspondingly arranged on the side of the plug hole 111a in any direction perpendicular to the first direction D1. The connector 171 may include a second positioning portion 171c. The second positioning portion 171c is located on the side of the connector 171 in any direction perpendicular to the first direction D1. One of the first positioning portion 101b and the second positioning portion 171c is configured as a positioning groove. The other of the first positioning portion 101b and the second positioning portion 171c is configured as a positioning boss. The positioning boss is inserted into the positioning groove to prevent the connector 171 from moving perpendicular to the first direction D1. The cooperation of the positioning boss and the positioning groove provides a fool-proof design. For those skilled in the art, the purpose and function of the fool-proof design are clear and will not be repeated here.

[0120] Optionally, the first positioning portion 101 b is a positioning groove, and the second positioning portion 171 c is a positioning boss. The positioning bosses are located on two opposite sides of the connector 171 in the third direction D3.

[0121] Further optionally, the plug-in component 171 may be a wedge-shaped block. The plug-in component 171 is provided with a second connection hole 171b for the fastener 172 to pass through. On the housing provided with the insertion portion 108, a third connection hole 101c extending along the first direction D1 is provided at a position of the housing corresponding to the second hole portion 108b. The fastener 172 passes through the second connection hole 171b of the plug-in component 171 and is fastened to the third connection hole 101c.

[0122] like Figure 6 and Figure 8 As shown, optionally, the fastener 172 is a bolt. The second connection hole 171b is a smooth hole. The third connection hole 101c is a threaded hole. By converting the axial tightening force of the bolt into a thrust along the second direction D2, the envelope size of the combination of the first housing 101 and the second housing 121 in the second direction D2 is effectively reduced.

[0123] Optionally, the size of the first sealing portion 103 along the second direction D2 is smaller than or equal to the size of the first housing 101 along the second direction D2. The size of the second sealing portion 123 along the second direction D2 is smaller than or equal to the size of the second housing 121 along the second direction D2. Accordingly, the size of the third sealing portion 152 along the second direction D2 is smaller than or equal to the size of the cover 151 along the second direction D2.

[0124] See also Figure 2 , Figure 5 as well as Figure 6 For example, the first housing 101 and the second housing 121 each have an axial end face 102 facing each other in the second direction D2. The motor assembly may further include a second seal 162. The second seal 162 is sealingly connected between the axial end face 102 of the first housing 101 and the axial end face 102 of the second housing 121. By providing the second seal 162, the sealing performance between the axial end face 102 of the first housing 101 and the axial end face 102 of the second housing 121 can be improved.

[0125] Optionally, the second seal 162 may be an integrally formed sealing soft rubber pad, sealing gasket, metal-clad liner or other sealing structure made of preformed materials, or a seal formed by applying a colloid sealing material with good fluidity and curing it.

In a plane perpendicular to the first direction D1, the rib 155 is located outside the housing 101. In a plane perpendicular to the third direction D3, the orthographic projection of the rib 155 is located at least partially overlapped with the orthographic projection of the first housing 101. By providing the rib 155, it is also possible to facilitate the positioning of the relative position of the cover 151 and the first housing 101 and the relative position of the cover 151 and the second housing 121 during the assembly process. Moreover, the rib 155 can also block the connection portion of the cover 151 and the first housing 101 and the connection portion of the cover 151 and the second housing 121 to a certain extent.

[0127] In the example in the figure, a first receiving portion 101a is formed at the end of the first housing 101 close to the second housing 121 in the second direction D2. A second receiving portion 121a is formed at the end of the second housing 121 close to the first housing 101 in the second direction D2. Here, the first receiving portion 101a and the second receiving portion 121a are virtual bodies. The first receiving portion 101a and the second receiving portion 121a are connected to each other, so that a receiving groove 131 is formed at the connection between the first housing 101 and the second housing 121. The receiving groove 131 is at least suitable for accommodating electrical components or devices such as capacitors.

[0128] Compared with the related art, in addition to the sealing structure between the axial end face 102 of the first housing 101 and the axial end face 102 of the second housing 121, between the first housing 101 and the cover 151, and between the second housing 121 and the cover 151, the embodiment of the utility model also effectively increases the sealing area of ​​the intersection of the first housing 101, the second housing 121 and the cover 151 through the cooperation of the first sealing part 103 and the second sealing part 123 with the third sealing part 152 at the intersection of the first housing 101, the second housing 121 and the cover 151, thereby enhancing the sealing performance of the intersection of the first housing 101, the second housing 121 and the cover 151. Therefore, the embodiment of the utility model can solve the problem of "unreliable sealing due to the fact that the connection between the electric control housing and the housing 101 and the connection between the adjacent housings 101 are not sealed at the same time".
