Description

Technical Field

[0001] The utility model relates to the technical field of water cooling of motor casings, in particular to a water-cooled motor casing. Background Art

[0002] In current water-cooled axial flux motors, the core is locked to the motor housing via locking bolts. The motor housing is shaped like an I-shaped column, with the core mounted on one side and a water channel on the other. Above the channel, a water channel cover is friction-welded to the motor housing. The motor housing water channel has an intestinal-shaped, rotating structure, so the motor housing bearing seat is isolated from the outer structure, with no connection. This results in poor motor housing stiffness, which in turn worsens the housing assembly modal characteristics and ultimately causes NVH issues in the assembly. Utility Model Content

[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Reference Figure 1 As shown, it is a structural diagram of the motor housing 100 in the prior art. The motor housing 100 has a housing bearing seat 200 inside, and a water channel 300 is provided between the housing bearing seat 200 and the outer side of the motor housing 100. The water channel 300 is an intestinal-shaped rotating structure. When the water channel 300 is closed by a cover plate, the housing bearing seat 200 and the outer side of the motor housing 100 are two isolated structures. There is no direct connection between the two, which has a greater impact on the overall modal of the motor housing 100 and is prone to cause assembly NVH problems.

[0029] In order to solve the problems in the prior art, Figure 2 As shown, the present invention provides a water-cooled motor housing, comprising a housing body 10, a bearing seat 20 and a first reinforcement member 30, wherein:

[0030] The housing body 10 has a receiving cavity 11 . An opening 12 is formed on a surface of the housing body 10 . The bearing seat 20 and the first reinforcement member 30 are both disposed in the receiving cavity 11 through the opening 12 .

[0031] The first reinforcement 30 includes multiple first reinforcements 30, which are arranged at intervals in the accommodating cavity 11. One end of each first reinforcement 30 is connected to the outer peripheral surface of the bearing seat 20, and the other end of the first reinforcement 30 is connected to the inner wall surface of the accommodating cavity 11, thereby utilizing the first reinforcement 30 to establish a connection relationship between the bearing seat 20 and the shell body 10, thereby improving the overall rigidity of the water-cooled motor shell.

[0032] In order to further improve the rigidity of the water-cooled motor housing, in the embodiment provided in the present application, a plurality of second reinforcement members 40 are further provided in the accommodating cavity 11, and at least one second reinforcement member 40 is provided between each adjacent two first reinforcement members 30. The two ends of the second reinforcement member 40 are respectively connected to the two adjacent first reinforcement members 30, so that a connection relationship is established between the two adjacent first reinforcement members 30, which is conducive to further improving the rigidity of the water-cooled motor housing.

[0033] When multiple second reinforcements 40 are provided between adjacent first reinforcements 30, both ends of at least one of the second reinforcements 40 are connected to two adjacent first reinforcements 30, and the remaining second reinforcements 40 can connect the shell body 10 to the first reinforcement 30, thereby further strengthening the rigidity of the water-cooled motor shell.

[0034] In a feasible embodiment, the first reinforcement member 30 is a first reinforcing rib extending from the bottom wall of the accommodating cavity 11 toward the opening 12. The first reinforcing rib extends to be flush with the opening 12, that is, the height of the first reinforcing rib is the same as the depth of the accommodating cavity 11. When the accommodating cavity 11 is closed by a welding cover plate, one end of the first reinforcing rib at the opening 12 can be abutted against the cover plate, thereby strengthening the connection between the bearing seat 20 and the shell body 10.

[0035] Furthermore, the second reinforcement member 40 is a second reinforcement rib, which extends from the bottom wall of the accommodating cavity 11 toward the opening 12. In order to ensure a good connection between the bearing seat 20 and the shell body 10, it is convenient to set a cooling water channel 50 in the shell body 10. The height of the second reinforcement rib in the accommodating cavity 11 should be less than the height of the first reinforcement rib in the accommodating cavity 11. Preferably, the height of the second reinforcement rib in the accommodating cavity 11 is half of the height of the first reinforcement rib in the accommodating cavity 11. On the one hand, it is convenient for the cooling water channel 50 to perform normal cooling work, and on the other hand, it can save costs.

[0036] In the embodiment provided in the present application, based on the premise that the first reinforcement 30 and the second reinforcement 40 are set in the accommodating cavity 11, the cooling water channel 50 is set by using the first reinforcement 30 and the second reinforcement 40. Figure 2 As shown, the cooling water channel 50 includes a water inlet 51, a water outlet 52, and a circulation channel (not shown). The water inlet 51 and the water outlet 52 are both disposed within the accommodating cavity 11. One end of the circulation channel communicates with the water inlet 51, and the other end of the circulation channel communicates with the water outlet 52. When the motor needs to be cooled, the coolant enters the circulation channel through the water inlet 51, absorbs heat, and is then discharged through the water outlet 52, thereby achieving cooling.

[0037] In a feasible embodiment, a flow interval 53 is formed between adjacent first reinforcement members 30, and the water inlet 51 and the water outlet 52 are respectively located in different flow intervals 53. The water inlet 51 and the water outlet 52 are respectively located in at least two adjacent flow intervals 53, so that a cooling water channel 50 can be formed, thereby realizing the cooling function of the cooling water channel 50.

[0038] Since the height of the first reinforcement 30 is the same as the depth of the accommodating cavity 11, in order to allow the coolant in the cooling water channel 50 to flow smoothly, a flow hole 31 is provided on each first reinforcement 30. The plurality of flow holes 31 constitute a flow channel, and the coolant flows in the flow channel to achieve cooling. Figure 1 As shown, the water inlet 51 and the water outlet 52 are respectively arranged in two adjacent flow intervals 53. The first reinforcement 30 between the water inlet 51 and the water outlet 52 is not provided with a flow hole 31, so that the coolant can only flow in one direction in the flow channel. That is, after the coolant enters the flow channel from the water inlet 51, it can only flow along the Figure 2 The water flows in a clockwise direction as shown and reaches the water outlet 52 .

[0039] To further improve cooling uniformity, the circulation channel should have a curved, serpentine structure. This allows the coolant to reach more areas as it flows through the channel, thereby providing better cooling for the motor housing. Therefore, the circulation holes 31 on two adjacent first reinforcement members 30 are at least partially offset to form a curved, circumferential circulation channel. During cooling, the coolant can reach both the inside and outside of the water-cooled motor housing, thereby absorbing more heat from the water-cooled motor housing.

[0040] Since a second reinforcement member 40 is provided between two adjacent first reinforcement members 30, in order to ensure that a circulation channel with a curved and rotating structure can be formed, two adjacent circulation holes 31 should be located on opposite sides of a second reinforcement member 40. Figure 2 As shown, the first reinforcement 30 is arranged along the radial direction of the accommodating cavity 11, and the two ends of the second reinforcement 40 connect the two adjacent first reinforcements 30. When the coolant flows, it needs to flow into the corresponding flow interval 53 from a flow hole 31 on one side of the second reinforcement 40. After passing the second reinforcement 40, it flows into the next flow interval 53 from the flow hole 31 on the other side of the second reinforcement 40, forming a flow path similar to an "S" shape, which has a curved and rotating structural feature, thereby forming a flow channel with a curved and rotating structure.

[0041] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
