[0048] like Figure 1-4As shown, this embodiment provides an installation and positioning structure for an integrated motor. The installation and positioning structure includes a motor housing 1, a reducer housing 2, and an adapter cover 3. The adapter cover 3 is disposed between the motor housing 1 and the reducer housing 2 for assembly with the motor housing 1 and the reducer housing 2. Further, the motor housing 1 has a first opening 11, one side of the adapter cover 3 covers the first opening 11, and a first positioning structure is provided between one side of the adapter cover 3 and the motor housing 1. After positioning by the first positioning structure, the adapter cover 3 is installed to the motor housing 1 by bolts or other means. The reducer housing 2 has a second opening 21, the other side of the adapter cover 3 covers the second opening 21, and a second positioning structure is provided between the other side of the adapter cover 3 and the reducer housing 2. After positioning by the second positioning structure, the adapter cover 3 is installed to the reducer housing 2 by bolts or other means.

[0049] Thus, the installation and positioning structure provided in this embodiment connects the motor housing 1 and the reducer housing 2 by setting an adapter cover 3. A first positioning structure and a second positioning structure are respectively set on both sides of the adapter cover 3. When installing the adapter cover 3 and the motor housing 1, the first positioning structure is used for positioning and reconnection. When installing the reducer housing 2 and the adapter cover 3, the second positioning structure is used for positioning and reconnection. This makes the installation convenient and quick, improving installation efficiency. Moreover, after installation, it can ensure the coaxiality and parallelism accuracy requirements between the rotor 141, stator 142, and reduction gear, thereby ensuring the reliable operation of the motor.

[0050] Preferably, the first positioning structure of this embodiment includes a first positioning protrusion 31 disposed on one side of the adapter cover 3 and a first positioning groove 12 disposed on the motor housing 1. When installing the adapter cover 3 and the motor housing 1, the first positioning protrusion 31 is inserted into the first positioning groove 12 to position the adapter cover 3 and the motor housing 1, and then they are connected by bolts. The second positioning structure of this embodiment includes a plurality of second positioning pins 32 disposed on the other side of the adapter cover 3 and a plurality of second positioning holes 22 disposed on the reducer housing 2. When installing the reducer housing 2 and the adapter cover 3, the second positioning pins 32 are inserted into the second positioning holes 22 to position the reducer housing 2 and the adapter cover 3, and then they are connected by bolts.

[0051] Of course, in other embodiments, the first positioning structure may also include a plurality of first positioning pins disposed on one side of the adapter cover 3 and a plurality of first positioning holes disposed on the motor housing 1; while the second positioning structure may also include a second positioning protrusion disposed on the other side of the adapter cover 3 and a second positioning groove disposed on the reducer housing 2.

[0052] like Figure 5-11As shown, this embodiment also provides an integrated motor, which is installed using the mounting and positioning structure described above.

[0053] The motor housing 1 houses a rotor 141. The output end of the rotor 141's main shaft 1411 passes through a bearing 1412 on the adapter cover 3 into the reducer housing 2. The reducer housing 2 also houses a gear set 23 and an output shaft 24. The output end of the rotor 141's main shaft 1411 is connected to the input end of the gear set 23, and the output end of the gear set 23 is connected to the inner end of the output shaft 24. The outer end of the output shaft 24 extends out of the reducer housing 2 and can be connected to an external tool via a key to transmit power. A sealing gasket 33 is also provided between the adapter cover 3 and the reducer housing 2 to ensure the oil seal within the reducer housing 2.

[0054] The main shaft 1411 is also connected to blades 1415, which are shown only in the figure. The specific shape and structure can be set as needed. During assembly, the rotor 141 and blades 1415 can be pre-connected to the adapter cover 3. Specifically, the output end of the main shaft 1411 is provided with a first-stage input gear 1413 in the gear set 23. One side of the first-stage input gear 1413 is limited by the bearing 1412 on the adapter cover 3, and the other side is locked by the locking member 1414. The locking member 1414 is preferably a concave-convex locking nut, such as a hard lock nut, so that the main shaft 1411 can be reliably locked and fixed regardless of whether it rotates forward or backward, which is suitable for motor forward and reverse rotation scenarios.

[0055] The motor housing 1 also houses a stator 142, and a baffle ring 1421 is installed on the end of the stator 142 facing the adapter cover 3. The baffle ring 1421 and the stator 142 can be pre-fixed to the motor housing 1 by bolts passing through them. The blades 1415 on the main shaft 1411 are disposed between the adapter cover 3 and the baffle ring 1421. When the main shaft 1411 rotates, the blades 1415 also rotate, thus forming an air-cooled motor.

[0056] like Figure 11-15 As shown, the integrated motor in this embodiment also includes a controller 131. Specifically, the motor housing 1 includes an upper chamber 13 and a lower chamber 14 arranged vertically. The stator 142 and rotor 141, and other main motor components, are disposed in the lower chamber 14, while the controller 131 is disposed in the upper chamber 13. This arrangement structure is more reasonable and compact, reducing the front-to-back axial length of the motor, making it smaller in size, and facilitating the installation and transportation of the motor.

[0057] In this embodiment, the motor housing 1 also has a mounting port 16. The first opening 11 and the mounting port 16 are staggered front to back and top to bottom, that is, the first opening 11 is located on the lower front side, while the mounting port 16 is located on the upper rear side, which facilitates structural layout, processing and installation. The controller 131 is inserted into the mounting port 16 for installation. A limiting rib is provided in the upper cavity 13 to limit the vertical and horizontal position of the controller 131. A limiting part 136 is also provided in the upper cavity 13 to limit the front end of the controller 131. The integrated motor in this embodiment also includes a rear cover 4. The rear cover 4 is provided with a pressing plate 41 that can press the rear end of the controller 131. When the rear cover 4 is connected and installed in the motor housing 1, it can press and fix the controller 131 in the upper cavity 13.

[0058] Specifically, such as Figure 13-15 As shown, the controller 131 includes a housing 1311 and a circuit board 1312 and its components. The housing 1311 has mounting edges 1313 on its left and right sides, and mounting holes 1314 are provided on the mounting edges 1313. The traditional installation method is to use these mounting holes 1314 with screws for installation. Furthermore, a left limiting rib 132 and a right limiting rib 133 are provided in the upper chamber 13 to limit the left and right positions of the outer shell 1311 of the controller 131. An upper limiting rib 134 is provided in the upper chamber 13 to limit the upper surface of the mounting edge 1313. A lower limiting rib 135 is provided in the upper chamber 13 to limit the bottom of the outer shell 1311 of the controller 131. A limiting rib or limiting surface or other limiting part 136 is provided on the front side of the upper chamber 13 to limit the front side of the outer shell 1311 of the controller 131. The rear cover 4 can be bolted to the motor housing 1. After connection, a certain clamping force is applied to the rear side of the outer shell 1311 of the controller 131 by the clamping plate 41.

[0059] Traditional controller mounting structures use screws to secure the controller 131 in conjunction with the mounting holes 1314 on the mounting edge 1313, requiring a certain amount of space for screwing. However, the mounting structure of this embodiment allows the controller 131 to be installed in various scenarios without considering whether there is sufficient space for screwing, and also makes installation and disassembly more convenient. Furthermore, this embodiment only limits the housing 1311 of the controller 131, without affecting the normal operation of its internal components.

[0060] In this embodiment, the motor housing 1 and rear cover 4 are preferably made of plastic to improve pressure resistance. They can also be manufactured using molds, increasing production efficiency and reducing costs. The adapter cover 3 and reducer housing 2 are made of metal to improve strength and ensure that the reducer housing 2 and adapter cover 3 press tightly against the sealing gasket 33, guaranteeing the sealing of the oil inside the reducer housing 2.

[0061] In this embodiment, air inlets 137 are provided on the front side of the upper chamber 13, such as directly in front and on the left and right sides. The housings of the air inlets 137 on the left and right sides are arc-shaped, so that they can be closer to the components on the controller 131 and can dissipate heat better and faster. The air inlet 137 at the front can be, but is not limited to, a brim-type or a concealed window type, which can play a certain role in dust prevention. The rear side of the upper chamber 13 is connected to the rear side of the lower chamber 14, and gas can flow from the rear side of the upper chamber 13 to the rear side of the lower chamber 14. Gaps for gas flow are also provided between the stator 142 and the motor housing 1, and between the rotor 141 and the stator 142. An air outlet 15 is provided on the front outer wall of the lower chamber 14; an air outlet 15 is also provided on the adapter cover 3, covering the first opening 11 and located outside the reducer housing 2. This air outlet 15 is preferably a concealed window type structure.

[0062] When the integrated motor requires heat dissipation during operation, the blades 1415 rotate with the main shaft 1411. External cold air enters from the front and left and right air inlets 137 of the upper chamber 13 of the motor housing 1, first passing through the controller 131 to cool it; then flowing from the rear of the upper chamber 13 to the rear of the lower chamber 14, and then forward to the baffle ring 1421. The baffle ring 1421 blocks the airflow at the outer periphery, causing the airflow to flow towards the center through the blades 1415. The blades 1415 are preferably a combination of axial and centrifugal blades, allowing part of the airflow to flow from the front air outlet 15 to the outside of the reducer housing 2 to dissipate heat from the reducer housing 2, while the other part of the airflow flows out from the air outlet 15 on the front outer wall of the lower chamber 14 of the motor housing 1. This forms an airflow channel, and because the airflow flows to the controller 131, the motor body, and the reducer, it can effectively dissipate heat from each component, improving the overall heat dissipation effect.

[0063] In this embodiment, the rear end of the main shaft 1411 is also provided with a bent blocking member 1416, forming a labyrinth structure to prevent dust and other impurities from entering the rear end of the main shaft 1411 and affecting its rotation. Similarly, in this embodiment, a pressure ring 42 is provided on the rear cover 4. The pressure ring 42 is pressed against the motor housing 1 at the rear end of the main shaft 1411 by an O-ring 43, which can prevent dust and impurities from affecting the rotation of the main shaft 1411 from the rear end.

[0064] Furthermore, the reducer housing 2 and the motor housing 1 are also connected together by a connecting base plate 6; the reducer housing 2 is also connected to a connecting flange 5, and the user can choose to install the integrated motor on the target device through the connecting base plate 6 or the connecting flange 5 as needed.

[0065] In this embodiment of the integrated motor, during assembly, the rotor 141 is connected to the adapter cover 3, and the main shaft 1411 of the rotor 141 passes through the bearing 1412 on the adapter cover 3. Then, a first-stage input gear 1413 is assembled at the front end of the main shaft 1411, and the locking piece 1414 is screwed on to form an assembly. The stator 142 and the wind baffle ring 1421 are fixed to the lower chamber 14 of the motor housing 1, forming an assembly. Then, these two assemblies are connected, that is, positioned by the first positioning structure, and one side of the adapter cover 3 is connected to the motor housing 1, so that the rotor 141 extends into the stator 142. Then, the controller 131 is installed into the upper chamber 13, the leads are configured, and the rear cover 4 is closed for fixation. Next, the reducer housing 2 with other gears, including the gear set 23, is installed on the other side of the adapter cover 3, and positioned by the second positioning structure during installation. Finally, the connecting flange 5 and the connecting base plate 6 are connected.

[0066] As can be seen from the above, the installation positioning structure and integrated motor provided in this embodiment are easy and quick to install, have high installation accuracy, and are stable after installation. The motor structure is compact, has a reasonable layout, and is small and simple.

[0067] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
