[0028] Example 1

[0029] The first embodiment of the present application provides a motor housing, such as Figures 1 to 5 As shown, the motor housing includes:

[0030] The intermediate housing 100 has a suspension structure 200 integrally formed on its outer side, and the intermediate housing 100 is provided with a first stiffening structure 300 at the suspension structure 200;

[0031] An end cover 400 is provided at one end of the intermediate housing 100. A bearing chamber 500 is provided inside the end cover 400. The bearing chamber 500 is provided with a first notch 410 and a second notch 420 communicating with the interior thereof for allowing cooling oil to enter and exit the bearing chamber 500. The end cover 400 is also provided with a second stiffening structure 600 to increase the structural strength of the end cover 400.

[0032] The electric control bracket 700 is detachably connected to the intermediate housing 100 , and the electric control bracket 700 is used to connect to the motor controller.

[0033] like Figure 1 As shown, in this embodiment, the motor housing is used as an external component of the motor, which is mainly used to arrange components such as the stator, rotor, and rotor bearings so that the motor can play its role. The motor can be a drive motor or a generator, which is not limited here. The intermediate housing 100 can be set as a thin-walled hollow structure, and the end cover 400 can be in the form of a thin sheet, and the end cover 400 can be set at one end of the intermediate housing 100. The intermediate housing 100 and the end cover 400 can be cast as one piece, and they can both be made of aluminum alloy. The end cover 400 can be used as the front end cover 400 of the motor housing, and at the other end of the intermediate housing 100, the rear end cover 400 can also be detachably connected.

[0034] Of course, in some embodiments, both the front and rear end covers 400 may be detachably connected to the intermediate shell 100; or the rear end cover 400 may be integrally provided with the intermediate shell 100, while the front end cover 400 may be detachably connected to the intermediate shell 100.

[0035] like Figure 1 As shown, a suspension structure 200 can be provided on the outside of the intermediate housing 100. The suspension structure 200 can be used to install and secure the motor housing, for example, connecting the motor housing to the vehicle chassis. The suspension structure 200 can be located in the middle of the intermediate housing 100 and can be integrally injection molded with the intermediate housing 100 to ensure its structural strength. The intermediate housing 100 is also provided with a first stiffening structure 300 at the suspension structure 200. The first stiffening mechanism is used to further enhance the structural strength of the intermediate housing 100 at the suspension structure 200.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, a bearing chamber 500 is further provided on the inner side of the end cap 400. The bearing chamber 500 is used to accommodate the rotor bearings, which can be mounted on the ends of the rotor to ensure smooth rotor rotation. A first notch 410 and a second notch 420 are also provided on the inner side of the end cap 400 on the sidewall of the bearing chamber 500. The first notch 410 and the second notch 420 are spaced apart along the circumference of the bearing chamber 500 and both communicate with the interior of the bearing chamber 500. The first notch 410 and the second notch 420 allow cooling oil to enter and exit the bearing chamber 500, cooling and lubricating the rotor bearings and thereby improving the cooling and lubrication efficiency of the motor housing as a whole. The first notch 410 can serve as the cooling oil inlet, while the second notch 420 can serve as the cooling oil outlet. When the motor housing is installed and secured, the first notch 410 can be located at the top of the bearing chamber 500, while the second notch 420 can be located near the bottom of the bearing chamber 500 to facilitate cooling access. A second stiffening structure 600 is further provided on the end cover 400 , and the second stiffening structure 600 is used to improve the structural strength of the end cover 400 .

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the motor housing also includes an electric control bracket 700. The electric control bracket 700 is used to connect to the motor controller, specifically, it can be connected to the controller housing of the motor controller to provide support for the motor controller during installation and fixation, thereby improving the structural stability of the motor controller. The electric control bracket 700 can be located near one end of the intermediate housing 100. It has an elongated structure, with at least one end protruding from the intermediate housing 100 and extending outward from the intermediate housing 100 to facilitate supporting the motor controller. The electric control bracket 700 can be an independent, split structure that can be cast separately and detachably connected to the intermediate housing 100.

[0038] It is understood that by integrally forming the relatively compact suspension structure 200 with the intermediate housing 100 and providing a first stiffening structure 300 on the suspension structure 200, the intermediate housing 100 can have a relatively high structural strength at the suspension structure 200. Furthermore, by separating the relatively wide and slender electric control bracket 700 from the intermediate housing 100 and providing a detachable connection, stress concentration on the electric control bracket 700 can be avoided, which could lead to insufficient structural strength at the electric control bracket 700. Therefore, the present application can ensure the overall structural strength of the intermediate housing 100. Furthermore, by providing a first notch 410 and a second notch 420 in the bearing chamber 500 of the end cover 400, the present application can ensure cooling and lubrication of the bearing chamber 500. Furthermore, by providing a second stiffening structure 600 on the end cover 400, the structural strength of the end cover 400 can be ensured. Based on the foregoing, the present application can comprehensively improve the problems of poor cooling and lubrication of the motor housing, as well as insufficient structural strength.

[0039] Specifically, the suspension structure 200 includes several screw-connector mounting columns 210, and the first stiffening structure 300 includes a first rib 310 and a second rib 320. The first rib 310 connects at least two screw-connector mounting columns 210, and the second rib 320 is arranged to intersect with the first rib 310.

[0040] like Figure 1 and Figure 3 As shown, in this embodiment, the suspension structure 200 can be configured as screw-type mounting posts 210 integrally cast with the intermediate housing 100. A plurality of screw-type mounting posts 210 can be provided; this embodiment uses three as an example, and the three screw-type mounting posts 210 can be distributed in a triangular pattern. Of course, in some embodiments, the screw-type mounting posts 210 can be provided in other numbers or distributed in other ways. The screw-type mounting posts 210 can be used to install and secure screws, and are provided with corresponding threaded holes; these screws can then be used to secure the intermediate housing 100.

[0041] The first stiffening structure 300 is used to enhance the structural strength of the intermediate housing 100 at locations corresponding to the three screw-mounting posts 210. It can be configured as a rib-like structure and include a first rib 310 and a second rib 320. The first rib 310 can be arranged parallel to the axis of the screw-mounting posts 210 and connect at least two of the screw-mounting posts 210. In this embodiment, a first rib 310 is provided between any two of the three screw-mounting posts 210. Of course, in some embodiments, the first rib 310 can simultaneously connect three or four screw-mounting posts 210 located on the same straight line, and the number of such connections is not specifically limited herein. The second rib 320 is arranged to intersect the first rib 310. In this embodiment, the second rib 320 can be arranged perpendicular to the axis of the screw-mounting posts 210, in which case the second rib 320 also remains perpendicular to the first rib 310. In some embodiments, the number of second ribs 320 may be multiple, and the arrangement angles of the multiple second ribs 320 relative to the first rib 310 may be different.

[0042] It can be understood that this embodiment, by setting the suspension structure 200 as a number of screw-connector mounting columns 210 and setting the first stiffening structure 300 as a first stiffening plate 310 and a second stiffening plate 320, not only facilitates the integral preparation and molding of the suspension structure 200 and the first stiffening structure 300 with the intermediate shell 100, but also ensures that the prepared first stiffening structure 300 can stably and effectively improve the structural strength of the intermediate shell 100 at the suspension structure 200.

[0043] More specifically, a plurality of first ribs 310 are provided between two screw-connector mounting posts 210 .

[0044] like Figure 3 As shown, in this embodiment, for example, the number of first ribs 310 between two screw-connector mounting posts 210 can be set as a plurality. For example, in this embodiment, there are two first ribs 310 between two screw-connector mounting posts 210. In this case, the two first ribs 310 can be set in parallel and can be respectively set on the inner and outer sides when the three screw-connector mounting posts 210 are distributed in a triangle. It should be noted that in this embodiment, two first ribs 310 can be set between some two screw-connector mounting posts 210, and there can be only one rib between two screw-connector mounting posts 210. Of course, in some embodiments, the number of first ribs 310 between two screw-connector mounting posts 210 can also be other numbers, such as three, four, etc.

[0045] It is understandable that in this embodiment, the number of first ribs 310 between the two screw mounting columns 210 can be set to be several, so that the effect of the first stiffening structure 300 in enhancing the structural strength of the suspension structure 200 can be reasonably set according to actual needs.

[0046] Specifically, the second stiffening structure 600 includes an annular rib 610 and radial ribs 620 . The radial ribs 620 are arranged along the radial direction of the annular rib 610 , and are arranged at intervals along the circumferential direction of the annular rib 610 .

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, the second stiffening structure 600 is used to improve the structural strength of the end cover 400. It can be set as a convex rib-shaped structure and include annular ribs 610 and radial ribs 620. The annular ribs 610 and radial ribs 620 can be integrally formed with the end plate. The annular ribs 610 can be set in a circular ring shape and can be coaxially arranged with the bearing chamber 500. The number of annular ribs 610 can be reasonably set according to actual needs, such as one, two or three. The radial ribs 620 intersect with the annular ribs 610 and can be arranged along the radial direction of the annular ribs 610. The radial ribs 620 can be set in a number, and the plurality of radial ribs 620 can be arranged at equal intervals along the circumference of the annular ribs 610.

[0048] It can be understood that, in this embodiment, by configuring the second stiffening structure 600 as the annular ribs 610 and the radial ribs 620 , the annular scattering structure formed can stably and effectively improve the structural strength of the end cover 400 .

[0049] More specifically, the second reinforcing structure 600 is disposed on both the inner and outer sides of the end cover 400 .

[0050] like Figure 1 and Figure 4 As shown, in this embodiment, for example, two groups of second stiffening structures 600 may be provided, and are respectively provided on the inner side and the outer side of the end cap 400. The two groups of second stiffening structures 600 provided on the inner side and the outer side of the end cap 400 may not be completely identical. For example, the second stiffening structure 600 provided on the outer side of the end cap 400 may include only one annular rib 610, while the second stiffening structure 600 provided on the inner side of the end cap 400 may include two annular ribs 610. Of course, in some embodiments, the two groups of second stiffening structures 600 provided on both the inner and outer sides of the end cap 400 may also be identical.

[0051] It can be understood that, in this embodiment, by arranging the second stiffening structure 600 on both the inner side and the outer side of the end cover 400 , the structural strength of the end cover 400 can be further improved.

[0052] More specifically, the first notch 410 and the second notch 420 are staggered along the circumference of the annular rib 610 and along the plurality of radial ribs 620 of the second stiffening structure 600 disposed on the inner side of the end cover 400 .

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, for example, in the second stiffening structure 600 arranged on the inner side of the end cover 400, the number of radial ribs 620 can be set to twelve. Of course, in some embodiments, the number of radial ribs 620 can also be other numbers, such as five, six, seven, etc. When the radial rib 620 is arranged, its end close to the axis of the end cover 400 extends to the outside of the bearing chamber 500. The first notch 410 and the second notch 420 provided on the side wall of the bearing chamber 500 are staggered with the radial rib 620 to avoid interference. At the same time, in this embodiment, an annular rib 610 located on the inner side can also be disconnected at the arc position corresponding to the first notch 410 and the second notch 420 to facilitate the flow of cooling oil on the end cover 400 and then in and out of the bearing chamber 500.

[0054] It can be understood that this embodiment can reduce the impact of the first notch 410 and the second notch 420 for improving the cooling and lubrication effects on the second stiffening structure 600 by staggering the first notch 410 and the second notch 420 along the circumferential direction with the radial rib 620, thereby ensuring the structural strength of the end cover 400 while allowing the cooling oil to freely flow in and out of the bearing chamber 500.

[0055] Specifically, a mounting platform 110 is provided on the outer side of the intermediate housing 100 , and one end of the electric control bracket 700 abuts against the mounting platform 110 and is locked and fixed by connecting bolts.

[0056] like Figure 1 and Figure 5 As shown, in this embodiment, for example, the outer side of the intermediate housing 100 can also be provided with a mounting base 110 for mounting and fixing the electric control bracket 700. The mounting base 110 can be integrally cast with the intermediate housing 100, and the top of the mounting base 110 can be set as a flat mounting surface, which can be prepared by machining. The electric control bracket 700 and the intermediate housing 100 can be detachably connected by connecting bolts, in which case one end of the electric control bracket 700 abuts against the mounting base 110. Correspondingly, the abutting surface of the electric control bracket 700 can also be prepared as a plane by machining to form an effective contact with the mounting base 110. The rod of the connecting bolt can then pass through the electric control bracket 700 and be screwed into the mounting base 110 to lock and fix the electric control bracket 700.

[0057] It can be understood that this embodiment provides a mounting base 110 on the intermediate shell 100, and locks and fixes one end of the electric control bracket 700 on the mounting base 110 through connecting bolts, so that the electric control bracket 700 and the intermediate shell 100 are firmly connected, and at the same time, the convenience of disassembly and assembly of the electric control bracket 700 and the intermediate shell 100 can be ensured.

[0058] More specifically, the connection bolts are arranged at intervals of at least two.

[0059] like Figure 1 and Figure 5 As shown, in this embodiment, for example, at least two connecting bolts can be provided for tightening and securing the mounting base 110, depending on actual needs. This embodiment uses two connecting bolts as an example. These two connecting bolts can be spaced apart in a direction away from the intermediate housing 100 along the electronic control bracket 700. When tightened, these two connecting bolts prevent the electronic control bracket 700 from shaking or deflecting.

[0060] Of course, in some embodiments, only one connecting bolt may be provided; and the electric control bracket 700 may be limited by other means, for example, a slot is provided on the mounting platform 110, and one end of the electric control bracket 700 is arranged in the slot when it abuts against the mounting platform 110.

[0061] Specifically, an oil collecting tank 120 and an oil cooler mounting structure 800 are further provided on the intermediate housing 100 . The oil cooler mounting structure 800 includes an oil cooling inlet 810 , and the oil collecting tank 120 is in communication with the oil cooling inlet 810 .

[0062] like Figure 1As shown, in this embodiment, the oil collection tank 120 can be formed by a recess in the sidewall of the intermediate housing 100, away from its axis. When the motor is installed, the oil collection tank 120 is located at the bottom of the intermediate housing 100, thereby facilitating oil collection. The oil cooler mounting structure 800 can be arranged outside the intermediate housing 100, serving as a location for mounting and securing the oil cooler. The oil cooler mounting structure 800 can specifically include four locations: an oil cooling inlet 810, an oil cooling outlet 820, a water cooling inlet 830, and a water cooling outlet 840. These four locations can be arranged in a rectangular array. The oil cooling inlet 810 can be connected to the oil collection tank 120 via an oil channel or other structure. The oil collected in the oil collection tank 120 can be pumped into the oil cooler through the oil cooling inlet 810. Furthermore, the oil cooling inlet 810 is connected to the oil cooling outlet 820 through the oil cooler, allowing the cooling oil entering the oil cooler to be discharged through the oil cooling outlet 820. The water cooling inlet 830 and the water cooling outlet 840 are used for cooling water to enter and exit the oil cooler respectively. When the cooling water and the cooling oil circulate in the oil cooler at the same time, heat exchange can be performed between the two to cool the cooling oil by the cooling water.

[0063] It is understandable that, in this embodiment, by providing the oil collecting tank 120 and the oil cooler mounting structure 800 on the intermediate housing 100 , the cooling effect of the entire motor housing can be further improved.

[0064] The implementation principle of a motor housing provided in the first embodiment of the present application is as follows:

[0065] During preparation, the end cover 400 is integrally cast with the intermediate housing 100. During the casting process, the suspension structure 200, the first stiffening structure 300, the mounting platform 110, and the oil collecting tank 120 are all integrally cast with the intermediate housing 100, and the second stiffening structure 600 and the bearing chamber 500 are all integrally cast with the end cover 400. Subsequently, a first notch 410 and a second notch 420 are machined into the side wall of the bearing chamber 500, and the top of the mounting platform 110 is machined into a mounting plane, and the oil cooler mounting structure 800 is prepared. Then, one end of the separately prepared electric control bracket 700 is abutted against the mounting platform 110, and the connecting bolts are passed through the electric control bracket 700 and screwed into the mounting platform 110 to lock and secure the electric control bracket 700.

[0066] The present application integrates the relatively compact suspension structure 200 with the intermediate housing 100 and provides a first stiffening structure 300 at the suspension structure 200, thereby ensuring that the intermediate housing 100 has a relatively high structural strength at the suspension structure 200. Furthermore, the relatively wide and slender electric control bracket 700 is separated from the intermediate housing 100 and detachably connected, thereby avoiding stress concentration at the electric control bracket 700 and the resulting insufficient structural strength of the electric control bracket 700. Therefore, the present application ensures the overall structural strength of the intermediate housing 100. Furthermore, the present application provides a first notch 410 and a second notch 420 at the bearing chamber 500 of the end cover 400, thereby ensuring the cooling and lubrication effects at the bearing chamber 500. Furthermore, the provision of a second stiffening structure 600 on the end cover 400 ensures the structural strength of the end cover 400. Based on the foregoing, the present application can comprehensively improve the problems of poor cooling and lubrication effects and insufficient structural strength of the motor housing.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
