Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, specifically to an ultra-small motor housing. Background Technology

[0002] In the field of motor manufacturing, the motor housing, as a key mechanical structural component, directly affects the motor's operational stability, heat dissipation efficiency, and assembly compactness through its dimensional accuracy and adaptability. With the increasing demand for miniaturization and lightweight motors from industries such as new energy vehicles and industrial automation equipment, the design and manufacturing of motor housings face even greater technical challenges.

[0003] Currently, some motors suffer from excessively large housing dimensions in practical applications. This not only increases the overall weight and space occupied by the motor, reducing its adaptability for installation in limited spaces, but also raises production costs due to increased material usage. Furthermore, an oversized housing hinders heat dissipation and heat conduction, easily leading to excessively high temperatures during motor operation, affecting performance and lifespan, and restricting the application of motors in high-precision, compact equipment. Therefore, there is an urgent need to improve and optimize existing motor housing design and manufacturing technologies. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: an ultra-small motor housing, wherein a linear motor module 6 and a rotary motor module 7 are disposed in the housing 1, the linear motor module 6 is used to drive the rotary motor module 7 to move up and down, and the linear motor module 6 and the rotary motor module 7 are connected by a connecting wire 5, including:

[0028] The cable tray cavity 8 is located on the side of the housing 1 near the rotary motor module 7, specifically above the housing 1 in the direction of the rotary motor module 7. The cable tray cavity 8 is used to accommodate the connecting wire 5, ensuring that the connecting wire 5 can be installed smoothly even when the housing 1 is reduced in size, thereby adapting to the size of the housing 1 and completing the layout of the ultra-small motor housing.

[0029] The slide rail mounting plate 9 is located on the side of the housing 1 near the linear motor module 6. The slide rail mounting plate 9 is used to support the linear motor module 6 and to connect the linear motor module 6. The slide rail mounting plate 9 is provided with a slot for engaging the slide rail in the slide rail mounting plate 9. When the linear motor module 6 drives the rotary motor module 7 to move up and down, the slide rail required for the up and down movement is set on the slide rail mounting plate 9, reducing the gap in the installation position and ensuring that the reduction of the housing 1 will not hinder the normal operation of the motor.

[0030] The housing 1 is also provided with mounting holes 11, which are used to accommodate pin headers. Pin headers are used to bridge circuits that are blocked or isolated, and are responsible for transmitting current or signals. There are also output holes 12 for displacing the rotary motor module 7. Output holes 12 allow the linear motor module 6 to drive the rotary motor module 7 to move up and down. Output holes 12 ensure that the output end of the rotary motor module 7 can move up and down freely. Therefore, the diameter of the output hole 12 matches the diameter of the motor rotor of the rotary motor module 7. There is also a mounting slot 13 for mounting the linear motor module 6. The mounting slot 13 is used to accommodate the linear motor module 6 and also meets the heat dissipation requirements of the mounting slot 13. It also makes subsequent maintenance and repair work more convenient. The housing 1 is also provided with a sealing plate 2, which is used to protect the linear motor module 6 and the rotary motor module 7.

[0031] A pipe is connected to the rotary motor module 7, and the other end of the pipe is connected to the ventilation structure 4 opened in the housing. This ensures that the rotary motor module 7 can exhaust air through the ventilation structure 4 after it is drawn in by the motor head. The ventilation structure 4 includes a first exhaust hole 41, which is opened on the side of the housing 1 and can be used as an option for exhaust. The specific exhaust during motor use needs to be determined according to the site conditions. A connecting pipe 42 and a second exhaust hole 44 are opened on the top of the housing 1. The second exhaust hole 44, like the first exhaust hole 41, can be used for exhaust. The second exhaust hole 44 and the connecting pipe 42 form a T-shaped pipe. The connecting pipe 42 can connect the first exhaust hole 41, the second exhaust hole 44 and the connecting hole 43 to ensure smooth exhaust. One end of the connecting pipe 42 is the connecting hole 43 and the other end is the first exhaust hole 41. The connecting hole 43 is connected to the pipe. Connectors 3 can be set on both the first exhaust hole 41 and the second exhaust hole 44. The connectors 3 are used to connect the remaining structures.

[0032] When used in a miniature motor housing, the linear motor module 6 and the rotary motor module 7 are installed in the housing 1. The linear motor module 6 is connected to the rotary motor module 7 via a connecting cable 5, which is housed in a cable tray cavity 8 located above the rotary motor module 7 within the housing 1, adapting to the dimensions of the housing 1. The linear motor module 6 is installed in the mounting slot 13 and supported by a slide rail mounting plate 9. A slot on the slide rail mounting plate 9 engages with the slide rail required for the linear motor module 6 to move up and down, thereby reducing the installation gap. The linear motor module 6 drives the rotary motor module 7 to move up and down through the output hole 12, the diameter of which matches the diameter of the motor rotor of the rotary motor module 7. Pins in the mounting hole 11 are used to transmit current or signals between blocked or isolated circuits. When the rotary motor module 7 is running, the motor head draws in air. The gas enters the connecting pipe 42 through the connecting hole 43 via the connected pipe and can be discharged through the first exhaust hole 41 or the second exhaust hole 44. The first exhaust hole 41 is located on the side of the housing 1, and the second exhaust hole 44 is located on the top of the housing 1. Both are connected to the connecting pipe 42 and together form the ventilation structure 4 to ensure smooth exhaust.
