[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

[0024] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] like Figures 1 to 3 As shown, the existing motor housing includes a motor housing 10, an electric control housing 20 and an electric control cover plate 30, wherein the motor housing 10 further includes a motor rear end cover 11 and a flange surface 12, and the integration is relatively low. The water path from the motor controller to the motor is connected by a water nozzle 40+water pipe 50+water nozzle 40. The water nozzle 40, the clamp 60 and the water pipe 50 have many types of parts, which are complicated to manufacture and have high costs. At the same time, the upper suspension 5 of the existing motor is located on the rear end cover 11 of the motor, and the dynamic stiffness of the upper suspension 5 is relatively low. The rear end cover 11 of the motor is separated from the electric control housing 20, so that the upper suspension 5 cannot be increased with reinforcement ribs, and the dynamic stiffness is not easy to improve. The motor housing of the utility model has a high integration, reduces the configuration of parts, reduces costs, and at the same time greatly improves the dynamic stiffness of the upper suspension. The embodiments of the utility model are explained in detail below.

[0026] Embodiment 1

[0027] A motor housing described in the utility model includes a first housing 1 and a second housing 2, wherein the first housing 1 and the second housing 2 are connected to form a housing cavity (not shown), wherein the housing cavity accommodates a motor 100 and a motor controller 200, wherein the first housing 1 is provided with a cooling channel 4, wherein the first housing 1 is connected to an oil cooler 3, wherein the cooling channel 4 passes through the motor controller 200 and is connected to a water path (not shown) in the oil cooler 3.

[0028] The outer side wall of the first shell 1 is provided with a suspension structure, and a reinforcement structure is provided between the suspension structure and the outer side wall of the first shell 1. The suspension structure includes an upper suspension 5, and the reinforcement structure includes a plurality of reinforcement ribs 6, and the reinforcement structure greatly improves the dynamic rigidity of the suspension structure. A cover plate 8 is provided on the first shell 1, and the second shell 2 is a flange shell, and the second shell 2 and the suspension structure are arranged on opposite sides of the first shell 1.

[0029] The cooling channel 4 includes a first cooling channel 41 and a second cooling channel 42. The first cooling channel 41 passes through the motor controller 200, and the second cooling channel 42 connects the first cooling channel 41 and the water path in the oil cooler 3. The first cooling channel 41 includes a water inlet 411, and the water inlet is connected to the water inlet pipe 71. The second cooling channel 42 is arranged on the side of the first shell 1, and the second cooling channel 42 includes a connecting channel 421 and a long channel 422. The connecting channel 421 is L-shaped, and the connecting channel 421 connects the first cooling channel 41 and the long channel 422. The long channel 422 extends from top to bottom, and the long channel 422 is connected to the water path in the oil cooler 3. The water path in the oil cooler 3 includes a water outlet (not shown), and the water outlet is connected to the water outlet pipe 72. The cooling water enters the first cooling channel 41 from the water inlet pipe 71 to cool the motor controller, and then enters the water path in the oil cooler 3 through the connecting channel 421 and the long channel 422 to cool and dissipate the heat of the motor. Finally, the cooling water flows out from the water outlet pipe 72, thereby realizing an integrated water path design, which can reduce multiple water path parts, including faucets, faucet bolts, clamps and water pipes.

[0030] The first housing 1 includes an upper housing 101 and a lower housing 102 which are integrally formed. The motor controller 200 is arranged in the accommodating cavity corresponding to the upper housing 101, and the motor 100 is arranged in the accommodating cavity corresponding to the lower housing 102. The lower housing 102 integrates part of the original motor housing and the rear end cover of the motor. The lower housing 102 is detachably fixedly connected to the second housing 2, and the motor 100 is arranged in the accommodating cavity corresponding to the second housing 2. In this embodiment, the lower housing 102 is connected to the second housing 2 by bolts, and the lower housing 102 is provided with motor structures such as a mechanical pump and a motor stator.

[0031] The first shell 1 of the utility model integrates the motor controller shell and part of the motor shell and the suspension structure, so that the first shell 1 can be injection molded at one time, the integration of the motor shell is improved, and the dynamic stiffness of the suspension structure is improved. At the same time, a cooling channel 4 is provided on the first shell 1, and the cooling channel 4 passes through the motor controller and is connected to the water path in the oil cooler 3. The cooling water flows into the water path in the oil cooler 3 through the cooling channel 4 and performs heat exchange with the oil path in the oil cooler 3.
