[0026] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration". Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] The present application provides a motor structure, as shown in the drawings, which comprises a motor 100, a flexible waterproof cover 200 and a sponge cover 300, the front end of the motor 100 is provided with a motor shaft 110, the flexible waterproof cover 200 covers the front end of the motor 100 and the motor shaft 110 passes through the flexible waterproof cover 200, the sponge cover 300 covers the rear end of the motor 100, and part of the sponge cover 300 covers the outside of the flexible waterproof cover 200. Figures 1 to 6 The present application provides a motor structure, as shown in the drawings, which comprises a motor 100, a flexible waterproof cover 200 and a sponge cover 300, the front end of the motor 100 is provided with a motor shaft 110, the flexible waterproof cover 200 covers the front end of the motor 100 and the motor shaft 110 passes through the flexible waterproof cover 200, the sponge cover 300 covers the rear end of the motor 100, and part of the sponge cover 300 covers the outside of the flexible waterproof cover 200.

[0028] Specifically, the flexible waterproof cover 200 covers the front end surface 101 of the motor 100 and part of the side surface 102 of the motor 100, the sponge cover 300 covers the rear end surface 103 of the motor 100 and another part of the side surface 102 of the motor 100, and the sponge cover 300 partially covers the outside of the flexible waterproof cover 200; the flexible waterproof cover 200 is provided with a through hole 205 through which the motor shaft 110 passes, and the side surface 102 of the motor shaft 110 is attached to the hole wall surface of the through hole 205 (i.e., the side surface 102 of the motor shaft 110 is tightly attached to the hole wall surface of the through hole 205), so as to ensure the sealing property.

[0029] The motor structure provided by the embodiments of the present application can effectively ensure the sealing property of the motor 100, avoid the erosion of the motor 100 by condensed water, realize the waterproof and moisture-proof protection of the motor 100, and further prevent the internal corrosion failure of the motor 100 in some severe working conditions (such as the seaside or high-temperature and high-humidity environment) for long-term use.

[0030] It can be understood that, since the flexible waterproof cover 200 and the sponge cover 300 directly cover the surface of the motor 100, the protection of the motor 100 can be realized in the smallest space, so that the volume of the entire motor structure is small, and the space occupation is small, and thus the motor structure can be applied to more air conditioner models, and the applicability is better.

[0031] Optionally, the inner surface of the flexible waterproof cover 200 is provided with an adhesive, and the inner surface of the sponge cover 300 is also provided with an adhesive, so as to better paste and seal.

[0032] In some embodiments of the present application, as shown in Figure 2 and Figure 4 , one end of the flexible waterproof cover 200 close to the sponge cover 300 is provided with an opening 201, and the edge of the opening 201 is provided with a notch 202; as shown in Figure 1 and Figure 5 , the edge of the sponge cover 300 is provided with a shielding part 301, and the shielding part 301 covers the notch 202. It can be understood that, since the motor 100 has a certain height, by arranging the notch 202 on the edge of the opening 201 of the flexible waterproof cover 200, the notch 202 can release the deformation amount of the flexible waterproof cover 200, reduce the resistance when the motor 100 and the flexible waterproof cover 200 are assembled, and thus facilitate the assembly of the motor 100 and the flexible waterproof cover 200.

[0033] Optionally, the width of the gap 202 gradually increases in the direction from the flexible waterproof cover 200 to the sponge cover 300, thereby further facilitating the assembly of the motor 100 and the flexible waterproof cover 200. For example, the gap 202 can be in a trapezoidal structure, and correspondingly, the shielding portion 301 of the sponge cover 300 is also in a trapezoidal structure, and the trapezoidal shielding portion 301 completely covers the trapezoidal gap 202.

[0034] Optionally, as shown in FIG. 2, the edge of the opening 201 of the flexible waterproof cover 200 is provided with a sawtooth structure 203. By providing the sawtooth structure 203 at the edge of the opening 201 of the flexible waterproof cover 200, the sawtooth structure 203 can be used to release the deformation amount of the flexible waterproof cover 200, thereby ensuring that the flexible waterproof cover 200 can well fit the surface of the stepper motor 100 under a certain deformation amount. Figure 4

[0035] In some embodiments of the present application, the flexible waterproof cover 200 is a transparent waterproof cover. That is, the flexible waterproof cover 200 is in a transparent structure, thereby facilitating the user to visually observe the joint gap between the front end face 101 of the motor 100 and the side face 102 of the motor 100.

[0036] Optionally, the flexible waterproof cover 200 can be a blistering piece made of PET (polyethylene terephthalate) material and has a certain deformation amount, so as to cover the front end of the motor 100. Of course, in other embodiments, the flexible waterproof cover 200 can also be made of other materials, which is not limited in the present application.

[0037] Optionally, the thickness of the flexible waterproof cover 200 is 0.3mm-0.6mm. By setting the thickness of the flexible waterproof cover 200 to be 0.3mm-0.6mm, the flexible waterproof cover 200 has a good deformation amount, thereby ensuring the smooth assembly of the motor 100, and at the same time, the installation space of the entire motor structure can be saved. For example, the thickness of the flexible waterproof cover 200 can be 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm or a range between any two of the above values.

[0038] In some embodiments of the present application, the motor 100 is provided with a mounting ear 120, and the mounting ear 120 is used to mount the motor 100 to an external structure (for example, the shell of an air conditioner); the flexible waterproof cover 200 is provided with a mounting hole 204, the mounting ear 120 is arranged in the mounting hole 204, and the side surface of the mounting ear 120 is attached to the hole wall surface of the mounting hole 204.

[0039] ​Optionally, the number of mounting ears 120 can be one or more, the number of mounting holes 204 is the same as the number of mounting ears 120, and the mounting ears 120 correspond one-to-one to the mounting holes 204. For example, as shown in Figure 3 and Figure 4 , the number of mounting ears 120 and the number of mounting holes 204 are both two, the two mounting ears 120 are symmetrically arranged, the two mounting holes 204 are symmetrically arranged, and the two mounting ears 120 are correspondingly arranged in the two mounting holes 204.

[0040] Optionally, as shown in Figure 2 , the height of the motor 100 is H, the height of the flexible waterproof cover 200 is H1, and 0.5H≤H1≤0.9H. In this way, the flexible waterproof cover 200 can ensure a certain protection area for the motor 100, and will not affect the assembly of the sponge cover 300.

[0041] In some embodiments of the present application, as shown in Figure 5 , the sponge cover 300 includes a main body 310 and a retaining edge 320 arranged around the edge of the main body 310, and the retaining edge 320 partially covers the outside of the flexible waterproof cover 200; the main body 310 is provided with a circle of dashed lines 302 along the circumferential direction of the main body 310, and the retaining edge 320 is provided with at least one solid line 303. By arranging a circle of dashed lines 302 on the main body 310, the side edge of the sponge cover 300 can be prevented from being raised after covering the motor 100; by arranging at least one solid line 303 on the retaining edge 320, the sponge cover 300 can be ensured to have no excessive redundancy after covering the motor 100. Specifically, the shielding part 301 is arranged on the edge of the retaining edge 320.

[0042] Optionally, the sponge cover 300 is of an integral structure, that is, the main body 310 and the retaining edge 320 are integrally formed.

[0043] Optionally, as shown in Figure 2 and Figure 5 , the height of the retaining edge 320 is H2, and H2≥7mm. By setting the height H2 of the retaining edge 320 of the sponge cover 300 to be greater than or equal to 7mm, the retaining edge 320 of the sponge cover 300 can be ensured to be firmly attached to the motor 100.

[0044] Optionally, as shown in Figure 6 , the length X of the retaining edge 320 covering the flexible waterproof cover 200 is X≥4mm. By setting the length X of the retaining edge 320 covering the flexible waterproof cover 200 to be greater than or equal to 4mm, the sponge cover 300 can effectively cover the motor 100, thereby improving the sealing performance of the motor 100.
