[0002] As one of the mainstream power components, electric motors are widely used in industry. With the development of current control technology and battery technology, electric motors are also widely used in automobile power systems as power components.

[0003] Existing automotive motor housings have limited functionality during use, relying solely on aluminum casings and heat dissipation fins for motor protection and cooling. However, when the motor is subjected to external impacts, the force acts directly on the motor housing, making it more susceptible to deformation and damage to internal components, resulting in low protective performance. Therefore, there is an urgent need for an automotive motor housing to address these issues. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3As shown, an automotive motor housing in this embodiment includes a housing body 1. Multiple sets of damping rods 4 are arranged in a circumferential array on the outer wall of the housing body 1. The damping rods 4 have built-in damping springs 9. A protective plate 3 is fixed on the movable part of the damping rods 4, which can effectively protect the motor housing and the components inside the motor. Heat dissipation fins 5 are also distributed in a circumferential array on the outer wall of the housing body 1, which can dissipate the heat generated during the operation of the motor and achieve heat dissipation inside the motor housing. A magnetic shielding layer 8 is provided on the inner wall of the housing body 1, which can prevent the components inside the motor from being interfered with by external magnetic fields and ensure the normal operation of the motor.

[0024] like Figures 1-3 In this embodiment, the fixed part of the damping rod 4 is fixedly connected to the outer shell body 1, the damping spring 9 is fixed between the movable part and the fixed part of the damping rod 4, and the protective plate 3 is welded to the outer wall of the damping rod 4. The protective plate 3 has an arc-shaped structure. During use, when the motor is subjected to external impact force, the damping rod 4, the damping spring 9 and the protective plate 3 can absorb and buffer the impact force together, thereby effectively protecting the motor shell and the parts inside the motor. At the same time, the initial position of the protective plate 3 is flush with the edge of the mounting flange 6 to ensure the specifications of the motor shell, making it easy to install and fix the motor, effectively improving the protective performance and use effect of the motor shell.

[0025] like Figures 1-3 In this embodiment, heat dissipation fins 5 are formed on the outer shell body 1. An end cap 2 is installed on one end of the outer shell body 1 by screws. A mounting flange 6 is fixed on the end of the outer shell body 1 away from the end cap 2. Mounting holes 7 are provided at the four corners of the mounting flange 6. The inner wall of the outer shell body 1 has a magnetic shielding layer 8, which is a ring structure. The initial position of the protective plate 3 is flush with the edge of the mounting flange 6. The components inside the motor are installed inside the outer shell body 1, and the assembled motor is fixed through the mounting holes 7 on the mounting flange 6. During use, the heat dissipation fins 5 can conduct heat generated during the operation of the motor, thereby dissipating heat inside the motor shell. The magnetic shielding layer 8 can prevent the components inside the motor from being interfered with by external magnetic fields, ensuring the normal operation of the motor.

[0026] The specific implementation process of this embodiment is as follows: The components inside the motor are installed inside the outer casing 1, and then the assembled motor is fixed through the mounting holes 7 on the mounting flange 6. During use, the heat dissipation fins 5 can conduct heat generated during the operation of the motor, thereby dissipating heat inside the motor casing. The magnetic shielding layer 8 can prevent the components inside the motor from being interfered with by the external magnetic field, ensuring the normal operation of the motor. When the motor is subjected to external impact force, the damping rod 4, the damping spring 9 and the protective plate 3 can absorb and buffer the impact force, thereby effectively protecting the motor casing and the components inside the motor, preventing the impact force from directly acting on the motor casing and causing serious damage to the motor. It has high protective performance and good use effect.
