Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation.

[0026] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.

[0027] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, an embodiment of the present application provides a motor housing, including a body 1, a suspension portion 10 is provided on one side of the body 1, and the suspension portion 10 is provided with a plurality of suspension bosses 11 spaced apart from each other. The motor housing also includes a first reinforcing rib 12 and a second reinforcing rib 13, the first reinforcing rib 12 at least partially extends along a plane perpendicular to the length direction of the suspension boss 11, and the first reinforcing rib 12 connects the plurality of suspension bosses 11. The second reinforcing rib 13 is connected between at least two adjacent suspension bosses 11, and the second reinforcing rib 13 is cross-arranged with the first reinforcing rib 12.

[0029] The motor housing provided in the embodiment of the present application is applied to the motor, and the motor is installed in the vehicle. The suspension part 10 is located at one side of the body 1, and the suspension part 10 is the part where the motor is connected to the whole vehicle.

[0030] The suspension boss 11 is substantially cylindrical in shape, and is provided with a threaded hole extending along its length direction. The motor is mounted on the suspension portion 10 by inserting a threaded fastener such as a bolt into the threaded hole.

[0031] like Figure 1 As shown, one end of the suspension boss 11 is connected to the upper surface of the suspension part 10, and the central axes of the plurality of suspension bosses 11 are parallel to each other. By arranging a plurality of suspension bosses 11 at intervals, the connection strength and connection uniformity between the motor and the suspension part 10 are improved, and the motor is prevented from falling off from the motor housing.

[0032] The first reinforcing rib 12 is in the shape of a sheet or a plate, and is connected to the outer side wall of each suspension boss 11, thereby connecting the plurality of suspension bosses 11 together and improving the overall strength of the plurality of suspension bosses 11. The first reinforcing rib 12 at least partially extends along a plane perpendicular to the length direction of the suspension boss 11, such as Figure 1 As shown, the first reinforcing rib 12 is in the shape of a flat plate and is parallel to the upper surface of the suspension portion 10 . The first reinforcing rib 12 is arranged transversely to connect the various suspension bosses 11 into one.

[0033] The number of the second reinforcing ribs 13 is one or more. The second reinforcing ribs 13 are sheet-shaped or plate-shaped and have an angle with the first reinforcing ribs 12 . For example, the second reinforcing ribs 13 are perpendicular to the first reinforcing ribs 12 and are longitudinally arranged on the upper surface of the suspension portion 10 .

[0034] By providing the cross-distributed first reinforcing ribs 12 and the second reinforcing ribs 13 , a reinforcing effect is achieved in both the length direction and the radial direction of the suspension boss 11 , which helps to improve the rigidity and mode of the motor housing.

[0035] In the prior art, the bottom of the suspension boss 11 is usually connected to the shell, and the suspension bosses 11 are connected to each other through vertical reinforcing ribs to strengthen the suspension structure. Since the diameter of the suspension boss 11 and the thickness of the reinforcing rib are different, there is a cross-sectional change in the part where the suspension boss 11 is connected to the vertical reinforcing rib, which will cause stress concentration and reduce the fatigue safety factor, which is not conducive to improving the overall structural strength and is detrimental to the mode and stiffness of the motor shell.

[0036] The motor housing provided in the embodiment of the present application utilizes a first reinforcing rib 12 to connect multiple suspension bosses 11 together. The size of the connection between the first reinforcing rib 12 and the suspension boss 11 is uniform and there is no cross-sectional change, thereby improving the overall strength and fatigue safety factor of the suspension boss 11.

[0037] The motor housing provided in the embodiment of the present application is capable of connecting the multiple suspension bosses 11 into one by providing a first reinforcing rib 12 extending along a plane perpendicular to the length direction of the suspension boss 11, and the first reinforcing rib 12 connects multiple suspension bosses 11, so that the cross-sectional size of the connection between the suspension boss 11 and the first reinforcing rib 12 is uniform without obvious mutation, thereby improving the overall strength and fatigue safety factor; by providing a second reinforcing rib 13 connected between at least two adjacent suspension bosses 11, the connection strength between the multiple suspension bosses 11 is further improved, the deformation of the suspension boss 11 is reduced, and it helps to improve the mode and stiffness of the motor housing.

[0038] In a specific embodiment, there are a plurality of first reinforcing ribs 12 , and the plurality of first reinforcing ribs 12 are spaced apart and distributed along the length direction of the suspension boss 11 .

[0039] For example, Figure 1 As shown, there are three first reinforcing ribs 12 , which are arranged at intervals along the length direction of the suspension boss 11 , and each first reinforcing rib 12 is connected to the outer side walls of the plurality of suspension bosses 11 .

[0040] Optionally, a plurality of first reinforcing ribs 12 are evenly spaced and distributed along the length direction of the suspension boss 11 to improve the strength uniformity of the suspension boss 11 .

[0041] In this embodiment, a plurality of first reinforcing ribs 12 are provided to improve the connection strength of the plurality of suspension bosses 11 in the length direction, thereby preventing the suspension bosses 11 from shaking.

[0042] In a specific embodiment, there are multiple second reinforcing ribs 13 , and each suspension boss 11 is connected to at least one second reinforcing rib 13 .

[0043] The second reinforcing ribs 13 can be used not only to connect adjacent suspension bosses 11, but also to connect other structures on the motor housing, such as the outer wall of the bearing hole, the oil channel, etc., which is beneficial to improving the overall strength of the motor housing.

[0044] Each suspension boss 11 may be connected to one or more second reinforcing ribs 13 to enhance the stability of the suspension boss 11 on the motor housing and improve the structural strength of the region where the suspension portion 10 is located.

[0045] In a further embodiment, at least one first reinforcing rib 12 is located on a side of the suspension boss 11 facing away from the suspension portion 10 .

[0046] like Figure 1 As shown, the side of the suspension boss 11 close to the top is the side away from the suspension portion 10 , and at least one reinforcing rib is located on the side of the suspension boss 11 close to the top.

[0047] The suspension boss 11 is usually subjected to the greatest stress and deformation at the top. By arranging at least one first reinforcing rib 12 on the side of the suspension boss 11 away from the suspension portion 10, the deformation of the top of the suspension boss 11 can be reduced, the stress on the top of the suspension boss 11 can be dispersed, and the fatigue safety factor of the motor housing can be improved.

[0048] In a further embodiment, a side surface of one of the first reinforcing ribs 12 facing away from the suspension boss 11 is flush with a side surface of the suspension boss 11 facing away from the suspension portion 10 .

[0049] like Figure 1 As shown, the upper surface of the first reinforcing rib 12 located at the uppermost part of the suspension boss 11 is flush with the upper surface of the suspension boss 11 .

[0050] The motor housing further comprises a suspension bracket, which is mounted on an end of the suspension boss 11 away from the suspension portion 10 .

[0051] In this embodiment, by setting the side surface of the first reinforcing rib 12 away from the suspension boss 11 to be flush with the side surface of the suspension boss 11 away from the suspension portion 10, the step difference between the first reinforcing rib 12 and the upper surface of the suspension boss 11 is eliminated, thereby facilitating the installation of the suspension bracket.

[0052] In a further embodiment, each first reinforcing rib 12 is provided with a through hole, and the edge of each through hole is connected to at least two second reinforcing ribs 13 , so that at least two second reinforcing ribs 13 surround and form a first cavity 14 .

[0053] Specifically, each first reinforcing rib 12 is provided with one or more through holes, which penetrate the first reinforcing rib 12 along the thickness direction of the first reinforcing rib 12. In the orthographic projection of the motor housing along the length direction of the suspension boss 11, the contour lines of the through holes of multiple first reinforcing ribs 12 overlap.

[0054] The edge of each through hole is connected to at least two second reinforcing ribs 13, and the at least two second reinforcing ribs 13 can be arranged in parallel or intersecting. The space enclosed by the at least two second reinforcing ribs 13 constitutes a first cavity 14. The first cavity 14 has an opening at least at the top of the suspension boss 11, which facilitates the second reinforcing ribs 13 to be demolded upward along the length direction of the suspension boss 11 after manufacturing.

[0055] In a specific embodiment, the first reinforcing ribs 12 and the second reinforcing ribs 13 are arranged to form a second cavity 15 , and the second cavity 15 has an opening on a side facing away from the body 1 .

[0056] In this embodiment, the first reinforcing rib 12 and the second reinforcing rib 13 are cross-arranged to form at least two second cavities 15. The second cavity 15 has an opening on the side away from the main body 1, which facilitates the first reinforcing rib 12 to be demolded from one side of the main body 1 after manufacturing, so that the depth of the gear side cavity at the bottom of the motor housing can be controlled, which helps to improve the mode and stiffness of the motor housing.

[0057] Among them, Figure 1 and Figure 3 As shown, in the case where there are multiple first reinforcing ribs 12 and multiple second reinforcing ribs 13, the first reinforcing ribs 12 and the second reinforcing ribs 13 form a grid frame structure, which effectively improves the connection strength between the multiple suspension bosses 11 and the rigidity of the motor housing.

[0058] In one embodiment, a plurality of suspension bosses 11 are staggered and distributed on the suspension portion 10 .

[0059] Figure 2 is a top view of the motor housing, such as Figure 2 As shown, the plurality of suspension bosses 11 are not arranged along a straight line on the suspension portion 10, but are staggered, which can expand the span between the plurality of suspension bosses 11, improve the stress condition on the suspension portion 10, and prevent stress concentration. Optionally, the plurality of suspension bosses 11 can be distributed on the suspension portion 10 in a matrix, annular, array, etc.

[0060] An embodiment of the present application also provides a motor, comprising the motor housing provided by any of the above embodiments.

[0061] The motor provided in the embodiment of the present application is capable of connecting the multiple suspension bosses 11 into one by arranging a first reinforcing rib 12 extending along a plane perpendicular to the length direction of the suspension boss 11, and the first reinforcing rib 12 connects multiple suspension bosses 11, so that the cross-sectional size of the connection between the suspension boss 11 and the first reinforcing rib 12 is uniform without obvious mutation, thereby improving the overall strength and fatigue safety factor; by arranging a second reinforcing rib 13 connected between at least two adjacent suspension bosses 11, the connection strength between the multiple suspension bosses 11 is further improved, the deformation of the suspension boss 11 is reduced, and it helps to improve the mode and stiffness of the motor housing.

[0062] An embodiment of the present application also provides a vehicle, comprising the motor provided in the above embodiment.

[0063] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
