The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.

[0035] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0037] The embodiment of the present application provides a protective cover 1, a motor assembly structure 7 and an air conditioner 8 to solve the problem that the existing motor 71 is difficult to install into the protective cover 1. The following will be described with reference to the accompanying drawings.

[0038] See also Figure 1 This embodiment provides a protective cover 1, which is used to be mounted on the motor 71 to enhance the waterproof ability of the motor 71. The other end of the motor 71 shell is fixedly connected to a fixing part 711 for installing the motor 71 on other equipment, and the output shaft 712 of the motor 71 passes through the other end of the motor 71 shell.

[0039] The protective cover 1 includes a first cover body 2 and a second cover body 3. The first cover body 2 is provided with a first receiving groove 21 into which one end of the power supply motor 71 extends. The second cover body 3 is provided with a second receiving groove 31 into which the other end of the power supply motor 71 extends. The second cover body 3 is also provided with a telescopic structure 36 for facilitating deformation of the second cover body 3.

[0040] See also Figure 1 and Figure 3 By providing the first cover 2 to protect one end of the motor 71 and providing the second cover 3 to protect the other end of the motor 71, the waterproof ability of the motor 71 is improved; by providing the telescopic structure 36 on the second cover 3, when the motor 71 is installed in the second accommodating groove 31, the opening and volume of the second accommodating groove 31 can be expanded by the telescopic structure 36, which is conducive to installing the motor 71 in the second accommodating groove 31 and solving the problem that the motor 71 is difficult to install in the protective cover 1.

[0041] See also Figure 1 and Figure 3The walls of the first accommodating groove 21 are shaped according to the shape of the motor 71 housing, so that when the motor 71 is accommodated in the first accommodating groove 21, the walls of the first accommodating groove 21 are tightly fitted against the motor 71 housing. The walls of the second accommodating groove 31 are shaped according to the shape of the motor 71 housing, so that when the motor 71 is accommodated in the second accommodating groove 31, the walls of the second accommodating groove 31 are tightly fitted against the motor 71 housing. In addition, the walls of the second accommodating groove 31 are provided with an interlocking groove 35 into which one end of the first sleeve 2 extends. By inserting one end of the first sleeve 2 into the interlocking groove 35, the first accommodating groove 21 and the second accommodating groove 31 can be combined to form an internal cavity for accommodating the motor 71.

[0042] See also Figure 1 and Figure 4 In order to facilitate the connection of the motor 71 with external equipment, the bottom of the second accommodating groove 31 is provided with a first avoidance hole 32 for the output shaft 712 of the power supply motor 71 to extend out of the second accommodating groove 31 and a second avoidance hole 33 for the fixing member 711 of the power supply motor 71 to extend out of the second accommodating groove 31. The second sleeve 3 is provided with a wiring hole 34, which passes through the second sleeve 3 and is connected to the second accommodating groove 31.

[0043] See also Figure 1 and Figure 4 The telescopic structure 36 is an expansion joint 361 formed on the side wall of the second housing 3. The expansion joint 361 extends through one end of the second housing 3 and communicates with the second accommodating groove 31. Furthermore, both the first housing 2 and the second housing 3 are made of elastic material, enabling the expansion joint 361 to expand the second housing 3, thereby temporarily increasing the opening and volume of the second accommodating groove 31 and facilitating installation of the motor 71 therein. Furthermore, the expansion joint 361 communicates with the wiring hole 34, allowing the wires of the motor 71 to be inserted into the wiring hole 34 through the expansion joint 361, facilitating the routing of the wires of the motor 71.

[0044] See also Figure 1 and Figure 4 A sealing rib 22 is integrally formed on the first housing 2 and is located on one side of the first housing 2 where the first accommodating groove 21 is formed. When the motor 71 is assembled into the protective sleeve 1, the sealing rib 22 extends into the second accommodating groove 31. One side of the sealing rib 22 abuts the housing of the motor 71, and the other side abuts the wall of the second accommodating groove 31 where the expansion gap 361 is formed. The expansion gap 361 faces the sealing rib 22. The provision of the sealing rib 22 not only strengthens the connection between the protective sleeve 1 and the housing of the motor 71, but also blocks the location of the expansion gap 361 on the second housing 3, thereby enhancing the protective capability of the protective sleeve 1.

[0045] See also Figure 1 and Figure 3The protective sleeve 1 also includes a fixing ring 4, a first connecting belt 5 and a second connecting belt 6. One end of the first connecting belt 5 is fixedly connected to the first sleeve 2, and the other end is fixedly connected to the second sleeve 3. One end of the second connecting belt 6 is fixedly connected to the second sleeve 3, and the other end is fixedly connected to the fixing ring 4. In this embodiment, the fixing ring 4, the first connecting belt 5 and the second connecting belt 6 are all made of elastic material. When the protective sleeve 1 is sleeved on the motor 71, the sealing rib 22 extends into the second accommodating groove 31, the first sleeve 2 extends into the interlocking groove 35, the fixing ring 4 is sleeved on the outer surface of the second sleeve 3, the fixing ring 4 tightens the second sleeve 3 to the first sleeve 2, and the second sleeve 3 tightens the first sleeve 2 to the motor 71 housing, which is beneficial to improving the protective ability of the protective sleeve 1. In addition, a fixing groove 37 for accommodating and limiting the fixing ring 4 is opened on the side wall of the second sleeve 3. The fixing groove 37 is an annular groove connected from end to end. When the fixing ring 4 is sleeved on the second sleeve 3, the fixing ring 4 is placed in the fixing groove 37.

[0046] In some embodiments of the present application, the retaining ring 4 can be used to limit the opening of the expansion joint 361. When the protective cover 1 is fitted over the motor 71, the retaining ring 4 is fitted over the outer surface of the second cover 3 to close the expansion joint 361. This allows the second cover 3 to be closely attached to the motor 71 housing after the motor 71 is assembled into the second cover 3, thereby enhancing the protective capability of the protective cover 1. When the expansion joint 361 is provided at the connection area between the second cover 3 and the first cover 2, the retaining ring 4, on the one hand, tightens the second cover 3 to the first cover 2, and on the other hand, closes the expansion joint 361, allowing the second cover 3 to be closely attached to the motor 71 housing. Through these two effects, the protective cover 1 is tightly and reliably fitted over the motor 71, providing good structural protection and a waterproof seal.

[0047] See also Figure 2 and Figure 3 This embodiment also provides a motor assembly structure 7, which includes the protective sleeve 1 and the motor 71 as described above. The first sleeve 2 is sleeved on one end of the motor 71, and the second sleeve 3 is sleeved on the other end of the motor 71. The output shaft 712 of the motor 71 extends from the first avoidance hole 32, the fixing piece 711 of the motor 71 extends from the second avoidance hole 33, and the fixing ring 4 is sleeved on the second sleeve 3.

[0048] It should be noted that, since the motor assembly structure 7 has the protective cover 1 in the above embodiment, it has at least some or all of the beneficial effects of the above embodiment of the protective cover 1, which will not be described in detail here.

[0049] See also Figure 5 and Figure 6 This embodiment further provides an air conditioner 8 , comprising the motor assembly structure 7 as described above, wherein the motor assembly structure 7 is arranged on a structural component of the air conditioner 8 .

[0050] The air conditioner 8 includes a support plate 81, a drive link 82, and multiple air guide assemblies. The air guide assemblies include blades 83 and rotating links 84. The blades 83 are rotatably connected to the support plate 81. The rotating links 84 are connected to the blades 83 and the drive link 82. The motor 71 is fixedly connected to the support plate 81 by bolts, and the output shaft 712 of the motor 71 is connected to any one of the blades 83. When the output shaft 712 of the motor 71 rotates, it can drive one of the blades 83 to rotate. The rotation of one blade 83 can drive the drive link 82 to move via the rotating link 84, thereby driving the other blades 83 to rotate synchronously, thereby adjusting the air direction of the air conditioner 8.

[0051] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0052] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
