[0002] In-wheel motors, also known as wheel-mounted motors, integrate power, transmission, and braking systems within the wheel hub, thus eliminating traditional automotive transmission components such as gearboxes, drive shafts, and differentials. They are a crucial technology in the electric vehicle field. In-wheel motors consist of a motor housing.

[0003] Patent document (CN108494145B) discloses a hub motor housing, including a housing body with a receiving cavity at one end and a through-hole in the bottom wall of the receiving cavity. In the above embodiment, annular heat sinks are provided on the outer side wall of the housing body to reduce the overall temperature of the hub motor. It should also be noted that, in addition to the passive heat dissipation implemented by heat sinks, existing technologies may also employ active heat dissipation methods, such as liquid cooling. In such cases, achieving a pre-fixed connection between the liquid cooling pipe and the housing body, along with a compact spatial arrangement, is one of the technical problems that those skilled in the art need to solve.

[0004] In addition, if the hub motor housing has multiple holes arranged in a ring array after stamping, the current practice is to deburr each hole one by one. However, in mass production, the deburring efficiency of the above method is low, and there is room for further improvement.

[0005] Therefore, there is a need for a motor housing that facilitates the connection between the liquid cooling pipe and the housing body, as well as a processing device for the motor housing that improves the deburring efficiency of the annular array holes. Summary of the Invention

[0023] Schematic motor housing, for reference Figures 1 to 2According to any preferred embodiment of the present invention, a motor housing includes a housing body 10, one end of which has a receiving cavity 101. The bottom wall of the receiving cavity 101 has a through first circular hole 1011, a second circular hole 1012, and a central hole 1013. The first circular hole 1011 and the second circular hole 1012 are arranged in a circular array and are arranged alternately. The distance between the central axis of the first circular hole 1011 and the second circular hole 1012 and the central axis of the central hole 1013 is equal. The bottom wall of the receiving cavity 101 also has a spiral groove 1014, which is located outside the first circular hole 1011 and the second circular hole 1012.

[0024] It should be noted that by providing the first circular hole 1011, conditions are provided for the connection between the motor housing and external components, and the hole of the first circular hole 1011 extends a predetermined distance in the direction towards the accommodating cavity 101; by providing the second circular hole 1012, conditions are provided for the accommodating cavity 101 to communicate with the outside and dissipate heat; by providing the central hole 1013, conditions are provided for the external rod to pass through the motor housing; by providing the spiral groove 1014, conditions are provided for the installation of the external spiral cooling pipe. Specifically, the external spiral cooling pipe can be placed in the spiral groove 1014, so that the cooling pipe is initially engaged with the spiral. The groove 1014 facilitates welding of the cooling pipe to the outer casing 10 by welders. Furthermore, by removing a portion of the space in the outer casing 10 to accommodate the cooling pipe, the cooling pipe occupies less space within the accommodating cavity 101. Compared to existing technologies, this design facilitates connection between the liquid cooling pipe and the outer casing 10, contributing to a more compact structure. In use, refrigerant can flow on the cooling pipe to provide active heat dissipation for the motor casing. It should also be noted that the outer casing 10 is integrally formed by stamping. Additionally, the ends of the first circular hole 1011 and the second circular hole 1012 need to be deburred.

[0025] A schematic diagram of a motor housing processing device, used for deburring the first circular hole 1011 and the second circular hole 1012 in the aforementioned motor housing, for reference. Figures 3 to 9 A processing apparatus for an electric motor housing according to any preferred embodiment of the present invention includes a base 20, a clamping assembly 30, and a deburring module 40.

[0026] Specifically, such as Figure 3As shown, the clamping assembly 30 includes a clamping base 301 and a three-jaw chuck 302. The clamping base 301 is fixedly connected to the machine base 20, and the three-jaw chuck 302 is disposed on the clamping base 301. Additionally, the deburring module 40 is flexibly mounted on the machine base 20 and positioned above the three-jaw chuck 302. Figures 4 to 7 As shown, the deburring module 40 includes a guide seat 401, a lifting member 402, multiple first sliding seats 403, a rotary drive device 404, and a reset elastic ring 405. The guide seat 401 is slidably mounted on the machine base 20, and the lifting member 402 is slidably mounted on the guide seat 401. The guide seat 401 has multiple first sliding grooves 4011 in the radial direction, and a first sliding seat 403 is slidably mounted in each first sliding groove 4011. A rotary drive device 403 is rotatably mounted on the first sliding seat 403. An output shaft 4031 is provided, and a deburring cone is fixedly installed at one end of the output shaft 4031 away from the guide seat 401. The rotary drive device 404 is fixedly installed on the guide seat 401. The rotating shaft of the rotary drive device 404 is poweredly connected to each of the output shafts 4031. When the lifting member 402 moves up and down, each of the output shafts 4031 slides inward or outward along the radial direction of the guide seat 401. The reset elastic ring 405 is sleeved on each of the first sliding seats 403.

[0027] It should be noted that the output shaft 4031 corresponds one-to-one with the first circular hole 1011 or the second circular hole 1012. Before processing, the outer casing 10 is clamped by the three-jaw chuck 302. It should be pointed out that the distance from the central axis of the three-jaw chuck 302 to each output shaft 4031 is equal. Subsequently, the operator can adjust the vertical position of the lifting member 402 according to the distance from the central axis of the first circular hole 1011 or the second circular hole 1012 to the central axis of the central hole 1013, so that each output shaft 4031 is in the height direction. For the corresponding first circular hole 1011 or second circular hole 1012, the output shaft 4031 is then rotated circumferentially and the guide seat 401 is moved downward. Then each of the deburring cones simultaneously deburrs each of the first circular hole 1011 or second circular hole 1012. Compared with the prior art, which requires deburring each of the first circular hole 1011 or second circular hole 1012 one by one, it has the advantages of being suitable for deburring multi-hole scenarios, improving the deburring efficiency of annular array holes, and being suitable for deburring processing of annular array holes with different spacing. Furthermore, in this application, if the three-jaw chuck 302 is fixed to the clamping seat 301 without circumferential rotation or translation, after machining the first circular hole 1011, the three-jaw chuck 302 can be released, and the circumferential position of the housing body 10 can be adjusted so that the second circular hole 1012 is directly opposite the output shaft 4031. If the three-jaw chuck 302 is provided on the clamping seat 301 without translation but with circumferential rotation, the three-jaw chuck 302 can be rotated after machining the first circular hole 1011. In the embodiment where the three-jaw chuck 302 is circumferentially rotatable, the processing equipment for the motor housing also includes a rotation limiting component for selectively restricting the circumferential rotation of the three-jaw chuck 302, such as a stop bolt threaded onto the clamping seat 301. When the stop bolt abuts against the three-jaw chuck 302, the circumferential rotation of the three-jaw chuck 302 is restricted.

[0028] It should also be emphasized that the core of the processing equipment for the motor housing is that, while taking into account the synchronous sliding of multiple output shafts 4031 in the radial direction, only one rotary drive device 404 is used to drive each output shaft 4031 to output.

[0029] Specifically, to further enable the rotary drive device 404 to drive each of the output shafts 4031 to perform an action, such as... Figure 7As shown, the deburring module 40 also includes multiple intermediate shafts 406 and a transmission belt 407. The rotary drive device 404 is located inside the output shaft 4031. A drive shaft 4041 is fixedly connected to the rotating shaft of the rotary drive device 404. The drive shaft 4041 is poweredly connected to each of the output shafts 4031 through the transmission belt 407. An intermediate shaft 406 is rotatably and movably mounted between the drive shaft 4041 and each of the output shafts 4031.

[0030] It should be noted that the inner side of the transmission belt 407 is in close contact with the intermediate shaft 406, the output shaft 4031 and the drive shaft 4041. When the drive shaft 4041 rotates circumferentially, the intermediate shaft 406 and the output shaft 4031 also rotate circumferentially. It should also be noted that when the lifting member 402 moves up and down, each output shaft 4031 slides inward or outward along the radial direction of the guide seat 401, and each intermediate shaft 406 moves away from or near the transmission belt 407 wound between the drive shaft 4041 and the output shaft 4031. When the intermediate shaft 406 moves away from the transmission belt 407 wound between the drive shaft 4041 and the output shaft 4031, it tightens the slack in the transmission belt 407 caused by the output shaft 4031 moving closer to the drive shaft 4041. Similarly, when the intermediate shaft 406 moves closer to the transmission belt 407 wound between the drive shaft 4041 and the output shaft 4031, the slack in the transmission belt 407 released by the intermediate shaft 406 is tightened again by the output shaft 4031. It should be noted that the linkage between the intermediate shaft 406 and the output shaft 4031 is the core of the processing equipment for the motor housing.

[0031] Furthermore, to specifically achieve the linkage movement between the intermediate shaft 406 and the output shaft 4031, such as... Figure 7 As shown, the lifting member 402 has a conical surface at one end near the output shaft 4031. Each of the first sliding seats 403 extends upward from the end opposite to the output shaft 4031 to form a first extension post 4032. The first extension post 4032 abuts against the conical surface, and the reset elastic ring 405 is sleeved on the first extension post 4032. Figure 8 and Figure 9 As shown, the deburring module 40 further includes a second extension post 4021, a connecting rod 4022, and an intermediate seat 4023, as... Figure 6As shown, the guide seat 401 also has a plurality of second slide grooves 4012, and an intermediate seat 4023 is slidably disposed in each second slide groove 4012. An intermediate shaft 406 is rotatably mounted on each intermediate seat 4023. One end of the second extension column 4021 is fixedly connected to the lifting member 402. The two ends of the connecting rod 4022 are rotatably connected to the second extension column 4021 and the intermediate seat 4023 respectively. The connecting rod 4022 is arranged at an inclination, and the height dimension of the end of the connecting rod 4022 near the second extension column 4021 is lower than the height dimension of the other end of the connecting rod 4022.

[0032] It should be noted that when the lifting member 402 moves downward: the first extension column 4032 is subjected to a horizontal force, and the downward movement of the lifting member 402 pushes each of the first extension columns 4032 to overcome the elastic force of the reset elastic ring 405 and slide radially away from the central axis of the drive shaft 4041; at the same time, the second extension column 4021 follows the lifting member 402 to move downward, and causes one end of the connecting rod 4022 and the intermediate seat 4023 to rotate at a predetermined angle toward the second extension column 4021. The lifting member 402 moves upward, pulling the intermediate seat 4023 along the second slide groove 4012 and closer to the transmission belt 407 located between the drive shaft 4041 and the output shaft 4031. When the lifting member 402 moves upward, the first extension column 4032 is reset by the elastic force of the reset elastic ring 405. At the same time, the upward movement of the lifting member 402 causes the connecting rod 4022 to flip in the opposite direction, and causes the intermediate shaft 406 to move away from the transmission belt 407 wound between the drive shaft 4041 and the output shaft 4031. It can be seen that in this application, one of the functions of the lifting member 402 is to make the output shaft 4031 slide radially, and the other function of the lifting member 402 is to make the intermediate shaft 406 slide accordingly and maintain the tension of the transmission belt 407. It should also be noted that, through the constraints of the first slide groove 4011 and the second slide groove 4012, both the first sliding seat 403 and the intermediate seat 4023 slide along the corresponding slide groove direction only.

[0033] Furthermore, to specifically achieve the vertical movement of the lifting component 402, such as... Figure 7 As shown, the deburring module 40 further includes a rotating component 408 and a guide rod 409. The rotating component 408 is rotatably mounted on the guide seat 401 and is threadedly connected to the lifting component 402. The guide rod 409 is fixedly connected to the guide seat 401 and passes through the lifting component 402.

[0034] Additionally, in this application, such as Figure 7 As shown, each of the intermediate shafts 406 is located on the same side of the line connecting the corresponding output shaft 4031 and the drive shaft 4041.

[0035] In addition, such as Figure 7 As shown, multiple transmission belts 407 are arranged at intervals in the axial direction of the drive shaft 4041.

[0036] Additionally, to facilitate the rotation of the rotating component 408, such as Figure 7 As shown, the rotating member 408 has a rotating handle 4081 at one end opposite to the output shaft 4031.

[0037] In addition, to achieve the vertical movement of the guide seat 401, such as Figure 3 As shown, the processing equipment for the motor housing also includes a lifting drive device 50, which is fixedly installed on the machine base 20 and is fixedly connected to the guide seat 401.

[0038] In summary, the motor housing and its processing equipment described in the embodiments of this application are explained, which provide the motor housing with the advantage of facilitating the connection between the liquid cooling pipe and the housing body, and provide the motor housing processing equipment with advantages such as improving the deburring efficiency of the annular array holes.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from these principles.
