[0001] The utility model relates to the technical field of air conditioners, in particular to an anti-twist structure for a driving mechanism and an air conditioner. Background Art

[0002] The air conditioner in the related technology usually includes an air guide plate, a driving mechanism, and a mounting base for installing the driving mechanism. The driving mechanism drives the air guide plate to rotate through an output shaft. However, due to the unreasonable structural design of the existing mounting base, the driving mechanism is always prone to twisting due to shaking, resulting in the output shaft and the air guide plate not rotating concentrically, and then colliding with the middle frame and other structures of the air conditioner, thereby generating noise.

[0003] The existing mounting base and the middle frame are usually fixed by screw columns. When the driving mechanism shakes, it is easy to affect the tightening effect of the threaded cooperation between the screw column and the threaded hole. After the driving mechanism has been running for a long time, the mounting base is prone to insufficient torsional force, resulting in unstable operation of the driving mechanism.

After the positioning column is inserted into the positioning hole, the first limiting member and the second limiting member cooperate with each other to limit the circumferential torsion of the mounting seat.

[0010] Further, the first limiting member includes a groove portion, and the second limiting portion includes a protruding portion, the groove portion is extended along the axial direction of the positioning hole, the protruding portion is formed on the outer peripheral surface of the positioning column, and after the positioning column is inserted into the positioning hole, the protruding portion is located in the groove portion.

[0011] Furthermore, a central angle of an arc formed by the groove portion along the circumference of the positioning hole is ≥180°.

[0012] Furthermore, the groove portion includes a first guide surface and two second guide surfaces, the first guide surface is arranged between the two second guide surfaces and intersects with the two second guide surfaces, and the protrusion is adapted to the shape of the groove portion.

[0013] Furthermore, an included angle between the first guide surface and the two second guide surfaces is an obtuse angle.

[0014] Furthermore, the first limiting member further includes an anti-retreat portion, and the anti-retreat portion is arranged beside the positioning hole and opposite to the groove portion.

[0015] Furthermore, two anti-twist components are provided, and the two anti-twist components are respectively located on two axially opposite sides of the output shaft of the driving mechanism.

Two anti-twist components are provided, and two of the second limit members in the two anti-twist components are respectively provided on the first side plate and the second side plate.

[0017] The second purpose of the utility model is to provide an air conditioner, the vibration of the driving mechanism of which is suppressed during operation, so that the air conditioner runs smoothly and reduces noise.

[0018] The second purpose of the utility model is achieved by the following technical solution:

[0019] An air conditioner comprises a driving mechanism and a middle frame, wherein the driving mechanism is mounted and fixed to the middle frame via the anti-twist structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0030] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] like Figure 1-Figure 5 As shown, the utility model discloses an anti-twist structure for a driving mechanism, which is used to fix the driving mechanism 104 on the middle frame 1000 of the air conditioner. The middle frame 1000 is provided with an installation space 100. The driving mechanism 104 has an output shaft 2. The anti-twist structure specifically includes a mounting seat 1 and an anti-twist assembly 10. The mounting seat 1 is used to install the driving mechanism 104. The anti-twist assembly 10 includes a first limit member and a second limit member. The first limit member is arranged on the mounting seat 1, and the second limit member is arranged on the middle frame 1000. After the driving mechanism 104 is installed on the mounting seat 1, they are installed together in the installation space 100. After the installation is completed, the first limit member and the second limit member cooperate with each other to limit the circumferential torsion of the mounting seat 1.

[0034] Generally speaking, in an air conditioner, the driving mechanism 104 is used to drive the air guide plate assembly to rotate to open or close the air outlet. During this process, if no anti-twisting structure is provided, the mounting base 1 and the middle frame 1000 are usually fixed by means of screw columns. When the driving mechanism 104 shakes, it is easy to affect the tightening effect of the threaded cooperation between the screw column and the threaded hole. After the driving mechanism 104 has been running for a long time, the mounting base 1 is prone to loosening of the screw column and the threaded hole due to insufficient torsional force, thereby causing the driving mechanism 104 to run unsteadily, thereby causing the air guide plate assembly to fail to open or close the air outlet, affecting use.

[0035] like Figure 5 As shown, on the basis of the above structure, on the one hand, when installing and fixing the mounting seat 1, when the output shaft 2 of the driving mechanism 104 is connected to the air guide plate assembly, the first stopper and the second stopper cooperate with each other, so that the mounting seat 1 and the middle frame 1000 are guided and positioned in the circumferential installation, thereby improving the assembly efficiency. On the other hand, after the installation is completed, when the driving mechanism 104 generates vibration during operation, since the first stopper and the second stopper are limited in the circumferential direction of the mounting seat 1, that is, when the mounting seat 1 has a circumferential rotation tendency along its mounting hole, the first stopper and the second stopper have rotation interference, which can timely prevent the mounting seat 1 from rotating in the circumferential direction, ensure the stable operation of the driving mechanism 104, and reduce the jitter noise.

[0036] like Figure 2As shown, specifically, a positioning hole 13 is provided on the mounting base 1, and a positioning column 14 is provided on the middle frame 1000. In this embodiment, a first limiting member is provided on the peripheral side of the positioning hole 13, and a second limiting member is provided on the positioning column 14. After the positioning column 14 is inserted into the positioning hole 13, the first limiting member and the second limiting member cooperate with each other to limit the mounting base 1 from rotating along the circumference of its positioning hole 13.

[0037] On the basis of the above structure, when the positioning hole 13 on the mounting base 1 is plugged into the positioning column 14 on the middle frame 1000, the first limiting member and the second limiting member can be guided to cooperate with each other, and after the positioning hole 13 and the positioning column 14 are plugged into place, the first limiting member and the second limiting member can be ensured to be installed in place, thereby effectively preventing the mounting base 1 from being twisted circumferentially along the positioning hole 13 after being installed in the middle frame 1000.

[0038] This embodiment guides and ensures that the first limit member and the second limit member are installed smoothly and in place by plugging the positioning hole 13 and the positioning column 14. Of course, in other embodiments, the positioning column 14 can also be set on the mounting seat 1, and the positioning hole 13 can be correspondingly set on the middle frame 1000, or other structures with guiding positioning such as a snap-on structure can also achieve the same effect.

[0039] like Figure 2 , Figure 3 and Figure 5 As shown, further, the first limiting member includes a groove portion 11, and the second limiting member includes a protruding portion 12. The groove portion 11 is extended along the axial direction of the positioning hole 13, and the protruding portion 12 is formed on the outer peripheral surface of the positioning column 14. After the positioning hole 13 on the mounting seat 1 and the positioning column 14 on the middle frame 1000 are plugged in, the protruding portion 12 is located in the groove portion 11.

[0040] It can be understood that the protrusion 12 is located behind the groove portion 11. If the mounting seat 1 is to be prevented from circumferential rotation, the protrusion 12 and the groove portion 11 must be able to interfere with each other in rotation, that is, the protrusion 12 and the groove portion 11 are respectively formed by at least two adjacent surfaces connected at an angle, that is, a snap-fit ​​surface is formed, so that rotation interference can occur during rotation, thereby limiting the circumferential rotation of the mounting seat 1.

[0041] Furthermore, in order to make the cooperation between the protrusion 12 and the groove 11 more stable, as shown in FIG. Figure 5As shown, the central angle of the arc formed by the groove portion 11 in the circumferential direction of the positioning hole 13 is ≥180°. If the central angle of the arc formed by the groove portion 11 and the circumferential direction of the positioning hole 13 is less than 180°, since the protrusion 12 and the groove portion 11 are both arranged around the circumference, it is obvious that the mutual cooperation between the groove portion 11 and the protrusion 12 is not stable enough. The larger the central angle of the arc formed by the groove portion 11 and the circumferential direction of the positioning hole 13, that is, by increasing the area of ​​the region where the groove portion 11 covers the protrusion 12 to increase the contact area where rotational interference occurs, the torsional force of the mounting seat 1 can be increased, making it more effective to limit the torsion of the mounting seat 1.

[0042] like Figure 5 As shown, specifically, the groove portion 11 of this embodiment includes a first guide surface 111 and two second guide surfaces 112. The first guide surface 111 is arranged between the two second guide surfaces 112 and intersects with the two second guide surfaces 112. At this time, the shape of the protrusion 12 is adapted to the shape formed by the first guide surface 111 and the two second guide surfaces 112.

[0043] On the basis of the above structure, when the mounting base 1 is installed in the mounting space 100, the positioning hole 13 is plugged into the positioning column 14. At the same time, under the guidance of the first guide surface 111 and the second guide surface 112 in the groove portion 11 on the outer peripheral surface of the positioning hole 13, the groove portion 11 smoothly abuts against the protrusion 12 arranged on the outer peripheral surface of the positioning column 14, and under the radial restriction of the positioning column 14 and the positioning hole 13, the groove portion 11 can be prevented from being separated from the protrusion 12, further ensuring that when the driving mechanism 104 shakes, the groove portion 11 on the mounting base 1 can rotate and interfere with the protrusion 12 on the middle frame 1000, thereby preventing the mounting base 1 from circumferential torsion.

[0044] More specifically, the angle between the first guide surface 111 and the two second guide surfaces 112 is an obtuse angle, which is compared to the acute angle or right angle between the first guide surface 111 and the two second guide surfaces 112. On the one hand, when the groove portion 11 and the protrusion 12 have rotational interference, the first guide surface 111 and the second guide surface 112 with an obtuse angle are not easy to deform, which can ensure the structural strength of the groove portion 11 and the protrusion 12 to a certain extent. On the other hand, when the positioning hole 13 and the positioning column 14 are plugged, the groove portion 11 can be prevented from being stuck by the angle between the first guide surface 111 and the second guide surface 112, which can improve the assembly efficiency of the mounting seat 1 to a certain extent.

[0045] Furthermore, the first position-limiting member of the present embodiment further includes an anti-retraction portion 131, which is disposed beside the positioning hole 13 and opposite to the groove portion 11. Figure 4 and Figure 5As shown, when the driving mechanism 104 vibrates, in the radial direction of the positioning column 14, when one end of the positioning column 14 used to be inserted into the positioning hole 13 is separated from the positioning hole 13, the positioning column 14 is no longer subject to the radial restriction of the positioning hole 13. Therefore, based on this structure, the circumferential surface of the positioning column 14 is also provided with an anti-retreat portion 131 which is enclosed by the groove portion 11. When the driving mechanism 104 moves axially, the circumferential surface of the positioning column 14 can abut against the anti-retreat portion 131 or the groove portion 11, thereby limiting the axial movement of the mounting seat 1 along the output shaft 2 of the driving mechanism 104.

[0046] It should be noted that the anti-retreat portion 131 of the present embodiment can be set to match the circumferential shape of the positioning column 14 on the side facing the positioning column 14, so as to better fit the circumferential surface of the positioning column 14 to prevent the positioning column 14 from moving in the axial direction of the output shaft 2 of the driving mechanism 104. Of course, in other embodiments, the anti-retreat portion 131 can also be set to a structure in which an arc surface and a bevel are connected, as long as it can limit the axial movement of the mounting seat 1 along the output shaft 2 of the driving mechanism 104 together with the groove portion 11.

[0047] like Figure 2 and Figure 3 As shown, further, in this embodiment, two anti-twist assemblies 10 are provided, and the two anti-twist assemblies 10 are respectively located on two opposite sides of the output shaft 2 of the driving mechanism 104 in the axial direction. In this way, since the opposite sides of the output shaft 2 can provide a relatively far installation spacing and can balance the force balance of the mounting seat 1, when the driving mechanism 104 shakes, the axial torsion of the mounting seat 1 is restricted to a larger extent in the circumferential direction, thereby further improving the operation stability of the driving mechanism 104.

[0048] like Figure 1-Figure 4 As shown, further, the installation space 100 includes a bottom plate 101, a first side plate 103 and a second side plate 102, and the bottom plate 101, the first side plate 103 and the second side plate 102 intersect and enclose each other to form the installation space 100. Two anti-twist assemblies 10 are provided, and the two second limit members in the two anti-twist assemblies 10 are respectively provided on the first side plate 103 and the second side plate 102. In this embodiment, the output shaft 2 of the driving mechanism 106 is connected to the air guide plate assembly toward and through the second side plate 102.

[0049] Specific as Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the top surface and the side surface of the mounting seat 1 are respectively provided with positioning holes 13, and correspondingly, the positioning column 14 of the first side plate 103 extends perpendicularly to the direction of the first side plate 103, and the positioning column 14 provided on the second side plate 102 is connected to the second side plate 102 through a connecting portion, the connecting portion is perpendicular to the direction of the second side plate 102, and the end of the connecting portion is perpendicularly connected to the positioning column of the second side plate 102, so that the positioning column of the second side plate 102 extends perpendicularly to the direction of the first side plate 103. Then, the two first limiting members can be respectively provided on the sides of the two positioning holes 13, and the two second limiting members can be respectively provided on the circumference of the two positioning columns 14. Of course, in other embodiments, the two positioning columns 14 can also be respectively provided on the bottom plate 101 and the first side plate 103, or on the bottom plate 101 and the second side plate 103, as long as the first limiting member can cooperate with the second limiting member when the mounting seat 1 is installed on the middle frame 1000, and limit the axial torsion of the mounting seat 1.

[0050] In this embodiment, a first limit member is arranged on different inner walls in the installation space 100, so that when the driving mechanism 104 shakes, the two second limit members on the top surface and the side surface of the mounting seat 1 rotate to interfere with the two first limit members on the two inner walls, thereby enhancing the torsional force of the mounting seat 1 and effectively preventing the mounting seat 1 from circumferential rotation.

[0051] The present application also provides an air conditioner, including a driving mechanism 104 and a middle frame 1000, wherein the driving mechanism 104 is installed and fixed to the middle frame 1000 through the above-mentioned anti-twist structure.

[0052] It can be understood that if the driving mechanism includes a gear mechanism, the mounting seat 1 can be a gear box or the like for mounting and protecting the gear mechanism.

[0053] By using the anti-twisting structure to install and fix the driving mechanism that drives the air guide plate assembly to rotate, not only the installation efficiency of the driving mechanism is improved, but also the vibration generated during the operation of the air conditioner can be suppressed, ensuring that the air conditioner runs quietly and smoothly.

[0054] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features.

[0055] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also considered to be within the protection scope of the utility model.
