Detailed Implementation

[0033] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0034] As shown in Figure 1, the motor air guide assembly of this embodiment includes an air guide frame 1, a mounting base 2, and a motor 3.

[0035] The air guide frame 1 is provided with a receiving cavity 11. For example, as shown in Figure 1, the material of the air guide frame 1 can be plastic, etc. The air guide frame 1 can be integrally injection molded and can extend along the left and right directions. The receiving cavity 11 can be a groove-shaped structure integrally formed on the air guide frame 1, and the receiving cavity 11 can be located on the left side of the air guide frame 1.

[0036] The mounting base 2 is detachably mounted on the air guide frame 1 and arranged opposite to the receiving cavity 11. For example, as shown in Figure 1, the mounting base 2 can be made of plastic or the like. The mounting base 2 can be integrally injection molded. The mounting base 2 can be mounted on the rear side of the air guide frame 1 by means of screw fixing, snap-fit, etc. In the front-back direction, the receiving cavity 11 can be located in front of the mounting base 2. The mounting base 2 can block the rear side of the receiving cavity 11.

[0037] The motor 3 is detachably mounted on the mounting base 2, with at least a portion of the motor 3 embedded within the receiving cavity 11. For example, as shown in Figure 1, the motor 3 can be a stepper motor 3. The motor 3 can be fixed to the front side of the mounting base 2 by means of screws, snap-fit, etc., and the entire motor 3 can be inserted into the receiving cavity 11, thereby facilitating the installation and fixing of the motor 3, achieving a proper fit between the air guide frame 1 and the motor 3, and also providing protection for the motor 3.

[0038] In the motor air guide assembly of this disclosure, the air guide frame 1 and the mounting base 2 are separately arranged, which facilitates the processing of the film on the mounting base 2 and improves the convenience of installation and disassembly.

[0039] In some embodiments, the mounting base 2 is disposed on the inner side of the air guide frame 1 facing the base, and the motor 3 is disposed on the outer side of the mounting base 2. It should be noted that, in actual assembly, the air guide frame 1 can be mounted on the front side of the base, wherein the base can be positioned facing the wall, and the air outlet can be located on the front side of the air guide frame 1. The inner side of the air guide frame 1 is the side of the air guide frame 1 facing the base, which is also the rear side of the air guide frame 1 in Figures 1 and 2, and the outer side of the air guide frame 1 is the side of the air guide frame 1 facing the outer panel or air outlet, which is also the front side of the air guide frame 1 in Figures 1 and 2.

[0040] This allows the receiving cavity 11 of the air guide frame 1 to protrude forward, thus enabling the installation of the motor 3 to make full use of the ample space on the front side of the air guide frame 1, achieving an optimized design for space utilization.

[0041] In some embodiments, the air guide frame 1 is connected to the mounting base 2 by a first fastener. One of the air guide frame 1 and the mounting base 2 is provided with a plurality of first columns 12 connected to the first fastener, and the other is provided with a plurality of first holes 21 through which the first fastener passes.

[0042] For example, as shown in Figure 1, the first column 12 can be integrally formed on the air guide frame 1. The first column 12 can be cylindrical, and the interior of the first column 12 can be provided with threaded holes. As shown in Figures 3 and 4, the first hole 21 can be a circular hole, and the first hole 21 can penetrate the mounting base 2 along the thickness direction of the mounting base 2.

[0043] The first fastener can be a screw or the like. During assembly, the first fastener can be passed through the first hole 21 and threaded onto the first column 12, thereby ensuring the structural stability of the connection between the air guide frame 1 and the mounting base 2.

[0044] In some embodiments, the first column 12 is disposed on the air guide frame 1, and the mounting base 2 is provided with a plurality of protrusions 22. The protrusions 22 protrude toward the inner side of the mounting base 2 and form a groove on the outer side of the mounting base 2 away from the base. The first column 12 is inserted into the groove and fitted therein. The first hole 21 is disposed on the bottom wall of the groove.

[0045] For example, as shown in Figure 2, there can be two first pillars 12. Both first pillars 12 can be integrally formed on the air guide frame 1 by injection molding, and both first pillars 12 can be located on the rear side of the air guide frame 1.

[0046] As shown in Figures 3 and 4, the mounting base 2 may be provided with two bosses 22. Both bosses 22 can be integrally formed on the mounting base 2 by injection molding. The bosses 22 can be arched. Each boss 22 can protrude to the rear side of the mounting base 2 and can be restricted to the front side of the mounting base 2. Each boss 22 may be provided with a first hole 21.

[0047] During assembly, the two first pillars 12 on the air guide frame 1 can be inserted into the grooves of the two bosses 22 one by one, thereby enhancing the limiting constraint effect between the air guide frame 1 and the mounting base 2. Secondly, the bosses 22 can also enhance the structural strength of the mounting base 2.

[0048] In some embodiments, the mounting base 2 includes a first plate portion 23 and a second plate portion 24 that are staggered in the inward and outward directions, and both the first plate portion 23 and the second plate portion 24 are provided with bosses 22.

[0049] For example, as shown in Figure 3, both the first plate portion 23 and the second plate portion 24 can be flat, wherein the dimensions of the first plate portion 23 are larger than those of the second plate portion 24. A boss 22 can be integrally formed on both the first plate portion 23 and the second plate portion 24.

[0050] The mounting base 2 can be positioned in the inward or outward direction, or in the front-back direction, and the first plate portion 23 can be located in front of the second plate portion 24. During assembly, the first plate portion 23 can be arranged opposite to the rear opening of the receiving cavity 11, and the second plate portion 24 can overlap the periphery of the opening of the receiving cavity 11, thereby enhancing the limiting and restraining effect of the mounting base 2 and the air guide frame 1.

[0051] In some embodiments, one of the air guide frame 1 and the mounting base 2 is provided with a buckle 26, and the other is provided with a slot 13, wherein the buckle 26 is engaged in the slot 13.

[0052] For example, as shown in Figure 4, the buckle 26 can be integrally formed on the mounting base 2, specifically located at the outer peripheral edge of the first plate portion 23. As shown in Figure 2, the slot 13 can be provided on the air guide frame 1, and the slot 13 can be located within the receiving cavity 11.

[0053] During assembly, the mounting base 2 and the air guide frame 1 can be pre-positioned and pre-fixed by the snap-fit ​​of the buckle 26 and the slot 13. Then, the air guide frame 1 and the mounting base 2 can be connected and fixed by the first fastener, which can improve the assembly efficiency and enhance the structural stability of the assembly of the air guide frame 1 and the mounting base 2.

[0054] In some embodiments, the motor 3 is connected to the mounting base 2 via a second fastener. The mounting base 2 is provided with a plurality of second pillars 25 connected to the second fastener on the outside of the receiving cavity 11. The motor 3 is provided with a plurality of second holes through which the second fastener passes.

[0055] For example, as shown in Figure 4, the second column 25 can be integrally formed on the front side of the mounting base 2. There can be two second columns 25, and each second column 25 can have a threaded hole. The outer periphery of the motor 3 can be provided with ear plates, and there can be two ear plates, each ear plate can have a second hole.

[0056] The second fastener can also be a screw, etc. During assembly, the second fastener can be passed through the second hole and threaded with the second column 25, thereby ensuring the structural stability of the assembly of the motor 3 and the mounting base 2.

[0057] In some embodiments, the outer periphery of the second column 25 is provided with a plurality of positioning ribs 251, the plurality of positioning ribs 251 protruding from the end of the second column 25 facing the receiving cavity 11, the plurality of positioning ribs 251 are arranged at intervals along the circumference of the second column 25, the motor 3 is provided with an ear plate, the ear plate is fitted within the space enclosed by the plurality of positioning ribs 251 to realize the assembly and positioning of the motor 3 and the mounting base 2, and a second hole is provided in the ear plate.

[0058] For example, as shown in Figure 4, each second column 25 may have three positioning ribs 251 on its outer periphery. The positioning ribs 251 may extend along the axial direction of the second column 25, and multiple positioning ribs 251 may be arranged at equal intervals along the circumference of the second column 25. Each positioning rib 251 may protrude from the free end of the second column 25, which is the end of the second column 25 that faces the motor 3. Thus, the three positioning ribs 251 may form a groove-shaped space at the free end of the second column 25.

[0059] During assembly, the ear plate on the outer periphery of the motor 3 can be first embedded in the groove-shaped space enclosed by the positioning rib 251, thereby achieving pre-positioning of the motor 3 during installation. Then, the electrode can be connected and fixed to the mounting base 2 with the help of the second fastener, thereby improving the overall assembly efficiency.

[0060] In some embodiments, the mounting base 2 is provided with a through hole 27 for the drive shaft 31 of the motor 3 to pass through the mounting base 2. For example, as shown in Figures 4 and 5, the through hole 27 can be an irregular hole structure, and the drive shaft 31 of the motor 3 installed in the receiving cavity 11 can extend from the through hole 27 to the rear side of the mounting base 2, thereby facilitating the connection and assembly of the motor 3 with the subsequent transmission shaft 4.

[0061] In some embodiments, as shown in Figures 5 to 7, the motor air guide assembly includes a drive shaft 4, the extension direction of the drive shaft 4 being perpendicular to the extension direction of the drive shaft 31, one end of the drive shaft 4 being rotatably connected to the drive shaft 31, and the other end of the drive shaft 4 being rotatably connected to the connecting rod 5 that drives the sweeping plate 6 to swing.

[0062] As shown in Figures 4 and 6, the mounting base 2 is provided with a limiting shaft 28, which is located inside the through hole 27. For example, the mounting base 2 may be integrally formed with an extension that can extend into the through hole 27, and the limiting shaft 28 may be integrally formed on the extension.

[0063] The limiting shaft 28 is coaxially arranged with the drive shaft 31. The transmission shaft 4 has a slot 41 on the side opposite to the drive shaft 31, and the limiting shaft 28 is rotatably assembled into the slot 41. For example, the transmission shaft 4 can be located between the limiting shaft 28 and the drive shaft 31, where the drive shaft 31 can be located in front of the transmission shaft 4, the limiting shaft 28 can be located in front of the transmission shaft 4, the slot 41 can be a circular groove and can be located in front of the transmission shaft 4, and the limiting shaft 28 can be a round shaft and can be directly inserted into the slot 41.

[0064] In use, the drive shaft 31 of the motor 3 can drive the transmission shaft 4 to swing. At this time, since the limit shaft 28 is connected to the transmission shaft 4 through the slot 41, the transmission shaft 4 can be avoided from being suspended, thus ensuring the stability of the transmission of the transmission shaft 4. This is conducive to driving each sweeping plate 6 into position through the connecting rod 5.

[0065] In some embodiments, the mounting base 2 is provided with a wire-holding groove 29, which is located at the circumferential edge of the mounting base 2 and is used to hold the wire. For example, as shown in FIG4, the wire-holding groove 29 can be provided in the first plate portion 23, and the circumferential edge of the first plate portion 23 can be provided with a slot. Two protrusions can be provided at the opening of the slot, and the two protrusions are arranged opposite to each other, making the wire-holding groove 29 a constricted structure. In use, the wires of the motor 3, etc., can be snapped into the wire-holding groove 29, thereby facilitating the limiting and fixing of the wires, etc.
