[0002] A reduction motor is a mechanical transmission device that converts the output of a high-speed, low-torque motor into a low-speed, high-torque motor, so that the original high-speed, low-torque motor output is converted into a low-speed, high-torque output. This can meet some occasions that require high torque and low speed, and at the same time, it can also reduce the output speed, reduce friction loss, vibration and noise in mechanical equipment, and increase the service life of the motor.

[0003] For a micro reduction motor, it generally includes a mounting sleeve, a driving motor, a reducer and a fixed end cover. A mounting opening is formed at one end of the mounting sleeve. The driving motor and the reducer are sequentially inserted into the mounting sleeve through the mounting opening. The fixed end cover is fixed at the mounting opening by screws so that the fixed end cover abuts the reducer to fix the driving motor and the reducer in the mounting sleeve.

[0040] Among them, the outer mounting sleeve 100 is formed with a mounting channel 101, which is respectively adapted to the drive motor 200 and the reduction device 300, and the two ends of the mounting sleeve 100 are respectively formed with a wire hole 102 and an mounting entrance 103, which are respectively connected to the two ends of the mounting channel 101, the wire hole 102 is used to pass the power line and the signal line, and the installation entrance 103 is the entrance for installing the drive motor 200 and the reduction device 300.

[0041] The driving motor 200 is sleeved in one end of the installation channel 101, that is, the driving motor 200 is located in one end of the installation channel 101 and is sleeved with the installation sleeve 100. The reduction device 300 is sleeved in the other end of the installation channel 101, that is, the acceleration mechanism is located in the other end of the installation channel 101 and is sleeved with the installation sleeve 100. The reduction device 300 is transmission-connected with the driving motor 200, so that the driving motor 200 drives the reduction device 300. The fixed end cover 400 covers the installation entrance 103 and is clamped with the installation sleeve 100. The fixed end cover 400 also abuts against one end of the reduction device 300 adjacent to the installation entrance 103, so as to integrate the driving motor 200 and the reduction device 300 in the installation sleeve 100, thereby improving the integration of the reduction motor 10.

[0042] In this embodiment, when installing the reduction motor 10, first, the driving motor 200 is installed into one end of the installation channel 101 through the installation entrance 103, and then the reduction device 300 is installed into the other end of the installation sleeve 100 through the installation entrance 103, and the reduction device 300 is connected to the driving motor 200 by transmission, and finally the fixed end cover 400 is clamped at the installation entrance 103 so that the fixed end cover 400 covers the installation entrance 103.

[0043] In the reduction motor 10 of the utility model, the driving motor 200 and the reduction device 300 are both sleeved in the installation channel 101, and the fixed end cover 400 abuts against one end of the reduction device 300 adjacent to the installation entrance 103, so that the fixed end cover 400 limits the reduction device 300 and the driving motor 200 in the installation channel 101, that is, the driving motor 200 and the reduction device 300 are both integrated in the installation sleeve 100, which improves the integration of the reduction motor 10 and the convenience of moving the reduction motor 10. Since the fixed end cover 400 covers the installation entrance 103 and is clamped with the installation sleeve 100, the fixed end cover 400 can be installed at the installation entrance 103 without the aid of auxiliary tools, which improves the assembly convenience and efficiency of the reduction motor 10.

[0044] In some preferred embodiments, a card interface 104 is provided at one end of the installation sleeve 100 adjacent to the installation inlet 103, and the fixed end cover 400 includes a cover member 410 and a card buckle 420. The cover member 410 covers the installation inlet 103, and the cover member 410 also abuts against one end of the speed reducer 300 adjacent to the installation inlet 103. One end of the card buckle 420 is fixedly connected to the cover member 410, and the other end of the card buckle 420 is carded into the card interface 104. In this embodiment, during the connection between the fixed end cover 400 and the installation sleeve 100, the card buckle 420 is deformed by the abutment of the installation sleeve 100. When the card buckle 420 is aligned with the card interface 104, the card buckle 420 is elastically reset and carded into the card interface 104, so as to realize the card connection between the fixed end cover 400 and the installation sleeve 100.

[0045] In some preferred embodiments, there are multiple card interfaces 104, which are arranged around and spaced apart along the circumference of the mounting sleeve 100. There are multiple buckles 420, which are correspondingly connected to the multiple card interfaces 104 one by one, thereby improving the firmness of the connection and further improving the structural stability of the reduction motor 10.

[0046] In some preferred embodiments, the installation sleeve 100 is formed with a guide bevel 105 at the installation entrance 103, and a guide bevel 421 is formed at one end of the buckle 420. The guide bevel 421 is slidably connected with the guide bevel 105 when the fixed end cover 400 is installed, making the buckle 420 easier to deform, reducing the difficulty of deformation of the buckle 420, and thereby improving the smoothness and efficiency of the snap connection.

[0047] In some preferred embodiments, the cover 410 includes an end cover body 411 and a bearing installation sleeve 412. The end cover body 411 covers the installation inlet 103 to seal the installation inlet 103. The bearing installation sleeve 412 is located in the installation channel 101 and is fixedly connected to the end cover body 411. The bearing installation sleeve 412 also abuts against one end of the reduction gear 300 adjacent to the installation inlet 103, so that the reduction gear 300 and the drive motor 200 are both fixed in the installation channel 101. One end of the buckle 420 is connected to the outer side of the bearing installation sleeve 412. In this embodiment, the bearing installation sleeve 412 is used to install the bearing of the reduction gear 300, so that the bearing installation sleeve 412 supports the output shaft of the reduction gear 300.

[0048] In some preferred embodiments, the card interface 104 is provided on the side of the installation sleeve 100 , which improves the processing convenience of the card interface 104 . Furthermore, the card interface 104 penetrates the side wall of the installation sleeve 100 .

[0049] Embodiment 2:

[0050] Based on the above embodiment, the structure of the reduction motor 10 is further optimized in this embodiment. Figures 2 to 5 .

[0051] The reduction motor 10 of this embodiment further includes an elastic structure 500, which is located in the installation channel 101. One end of the installation sleeve 100, the drive motor 200, the reduction device 300 and the fixed end cover 400 are abutted in sequence, so that the drive motor 200 and the reduction device 300 are both installed in the installation channel 101. In this embodiment, since the elastic structure 500 is elastic, it is ensured that one end of the installation sleeve 100, the drive motor 200, the reduction device 300 and the fixed end cover 400 can abut in sequence, which improves the tightness of the fixed end cover 400 and the installation sleeve 100, and at the same time improves the positional stability of the drive motor 200 and the reduction device 300, and suppresses the problem of the drive motor 200 and the reduction device 300 shaking in the installation channel 101.

[0052] In some preferred embodiments, the installation sleeve 100 includes a sleeve body 110 and a limiting portion 120, the installation channel 101, the wire hole 102 and the installation entrance 103 are all formed in the sleeve body 110, the limiting portion 120 is located in one end of the installation channel 101 adjacent to the wire hole 102, and the limiting portion 120 is also fixedly connected to the sleeve body 110, and the limiting portion 120, the elastic structure 500, the drive motor 200, the speed reduction device 300 and the fixed end cover 400 are abutted in sequence. In this embodiment, the elastic structure 500 is limited by the limiting portion 120, which avoids the problem of the elastic structure 500 being offset, and ensures that the elastic structure 500 can abut against the drive motor 200.

[0053] In some preferred embodiments, the elastic structure 500 includes a plurality of elastic blocks 510, which are all located at one end of the installation channel 101, and the plurality of elastic blocks 510 surround and are spaced along the circumference of the installation channel 101, and one end of the installation sleeve 100, each elastic block 510, the drive motor 200, the speed reducer 300 and the fixed end cover 400 are abutted in sequence. In this embodiment, the plurality of elastic blocks 510 surround and are spaced along the circumference of the installation channel 101, and each elastic block 510 abuts against the drive motor 200, which not only improves the force uniformity of the drive motor 200, but also reduces the material used in the elastic structure 500, which is conducive to reducing the cost of the elastic structure 500.

[0054] Furthermore, the limiting portion 120 includes a plurality of limiting ribs 121, which surround and are spaced along the circumference of the installation channel 101, and a space for the power line to pass through is formed between two adjacent limiting ribs 121, thereby preventing the limiting portion 120 from blocking one end of the installation channel 101 and reducing the material used for the limiting portion 120. Furthermore, the sleeve body 110 and the limiting portion 120 are connected together by integral molding, that is, the installation sleeve 100 is an integrally molded structure.

[0055] In some preferred embodiments, each elastic block 510 is also embedded in one end of the driving motor 200. When installing the elastic structure 500, each elastic block 510 is embedded in the driving motor 200. When the driving motor 200 is installed into the installation channel 101, the driving motor 200 drives the elastic structure 500 so that the elastic structure 500 is installed into the installation channel 101, thereby improving the convenience and efficiency of installing the elastic structure 500.

[0058] A sweeping robot comprises a reduction motor 10 and a sweeping mechanism, wherein the sweeping mechanism is connected to the output shaft of the reduction motor 10, and the sweeping mechanism is driven to rotate by the reduction motor 10, so that the sweeping mechanism can realize the sweeping function.

[0059] In the sweeping robot of the present utility model, the driving motor 200 and the reduction device 300 are both sleeved in the installation channel 101, and the fixed end cover 400 abuts against one end of the reduction device 300 adjacent to the installation entrance 103, so that the fixed end cover 400 limits the reduction device 300 and the driving motor 200 in the installation channel 101, that is, the driving motor 200 and the reduction device 300 are both integrated in the installation sleeve 100, which improves the integration of the reduction motor 10 and the convenience of moving the reduction motor 10. Since the fixed end cover 400 covers the installation entrance 103 and is clamped with the installation sleeve 100, the fixed end cover 400 can be installed at the installation entrance 103 without the aid of auxiliary tools, which improves the assembly convenience and efficiency of the reduction motor 10.
