DETAILED DESCRIPTION

[0021] Existing air conditioners use movable panels and panel drive mechanisms to realize the opening and closing movement of the panel, thereby opening or closing the corresponding window (such as the air outlet). However, the transmission process of the existing panel drive mechanism has the problem of insufficient stability. In order to improve the problem of insufficient stability of the panel drive mechanism in the prior art, the embodiment of the present application provides a panel drive mechanism and an air conditioner including the panel drive mechanism. The specific embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of the cooperation between the panel driving mechanism 100 and the panel 200 in one embodiment of the present application;

[0023] Figure 2 This is a schematic diagram of the interior of the driving box of the panel driving mechanism 100 in one embodiment of the present application. Figure 1 and Figure 2 The panel driving mechanism 100 provided in the embodiment of the present application includes a driving assembly, a driving box, and a rack 150 partially located in the driving box. The rack 150 can move along its own length direction under the drive of the driving assembly. The driving box has an opening, one end of the rack 150 is located in the driving box, and the other end extends from the opening to the outside of the driving box and is connected to the panel 200. When the driving assembly drives the rack 150 to move, the panel 200 can move under the drive of the rack 150. Figure 2As shown, the panel driving mechanism 100 can be arranged on the inner side of the panel 200. Since the rack 150 is inclined, the movement mode of the panel 200 can be a translational movement as a whole along with the inclination of the rack 150, or it can be a movement up and down as a whole and flip to a certain degree. For example, when the rack 150 is pushed upward obliquely, the panel 200 moves upward as a whole and flips outward at a certain angle.

[0024] like Figure 2 As shown, the drive assembly includes a drive member 130 and a gear 140. The gear 140 is located in the drive box and meshes with the rack 150. Optionally, the drive member 130 is fixedly connected to the outside of the drive box, and the drive shaft of the drive member 130 penetrates the drive box and is connected to the gear 140. The drive member 130 is fixed to the outside of the box body 110, which can effectively reduce the size of the drive box, and the drive member 130 can be repaired without opening the drive box, which also facilitates the maintenance of the drive member 130. The rack 150 is driven by the drive member 130 and the gear 140, and such a driving and transmission mode is stable and reliable. In an optional embodiment, the drive member 130 is a stepping motor, which can make the opening and closing of the panel 200 more stable and reliable. In other optional embodiments of the present application, the drive member 130 can also be arranged inside the drive box.

[0025] In this embodiment, the drive box includes a box body 110 and a box cover 120, and the box body 110 and the box cover 120 are detachably connected by a buckle structure. By detachably connecting the box body 110 and the box cover 120 by the buckle, it is convenient to inspect and maintain the rack 150 in the drive box and related components of the drive assembly. The buckle structure is stable and convenient, which is conducive to the efficient loading and unloading of the box cover 120. Of course, in other embodiments of the present application, fasteners such as bolts can also be used to achieve the detachable connection between the box cover 120 and the box body 110.

[0026] Specifically in this embodiment, the buckle structure includes a spring sheet 122 disposed on the box cover 120 and a boss 115 disposed on the box body 110, and a matching hole matched with the boss 115 is disposed on the spring sheet 122. When the boss 115 is embedded in the matching hole, the assembly of the box cover 120 is completed. Applying an external force to deform the spring sheet 122 can release the matching between the matching hole and the boss 115. Such a buckle structure can realize the loading and unloading of the box cover 120 quickly and stably. One or more buckle structures can be arranged between the box body 110 and the box cover 120. Between the box cover 120 and the box body 110, one side can be hinged and the other side can be buckle structured, or multiple buckle structures can be arranged at intervals at the matching position of the box cover 120 and the box body 110.

[0027] Figure 3 This is a schematic diagram of the interior of the drive box after the rack 150 is removed in one embodiment of the present application; Figure 4This is a schematic diagram of the structure of the rack 150 in one embodiment of the present application. Figure 3 and Figure 4 , in order to make the rack 150 more stable when it moves relative to the drive box. In the embodiment of the present application, a first slider 152 is provided on the rack 150, a first slide 113 cooperating with the first slider 152 is provided on the drive box, a second slider 114 is provided on the drive box, and a second slide 154 cooperating with the second slider 114 is provided on the rack 150. The extension direction of the first slide 113 and the second slide 154 is consistent with the length direction of the rack 150. Such a slide-slider matching structure allows the rack 150 to be limited to move in its length direction, so its movement direction is fixed. The two sets of slide strokes overlap each other to ensure that the rack 150 is always guided during the movement, and there are two sliders at the end of the stroke as end limits to prevent the rack 150 from sliding out of the drive box during the movement.

[0028] By respectively providing a slide groove and a slider on the rack 150 and the drive box, the rack 150 can be effectively guided when the drive assembly drives the rack 150 to move, and the rack 150 can drive the panel 200 to open and close when it slides along its length. The first slider 152 is provided on the rack 150, and the first slide groove 113 cooperating therewith is provided on the drive box; the second slider 114 is provided on the drive box, and the second slide groove 154 cooperating therewith is provided on the rack 150. Compared with providing all the sliders on one of the rack 150 or the drive box, and providing all the slide grooves on the other, the structure provided in the embodiment of the present application helps to improve the stability of the cooperation between the drive box and the rack 150. Moreover, in the sliding direction, the slide groove has a longer size, while the slider has a relatively smaller size. The first slide groove 113 and the second slide groove 154 are respectively arranged on the drive box and the rack 150, which is also conducive to realizing the matching structure of the double slide grooves, so that the two slide grooves are not distributed on the drive box or the rack 150 and are not too crowded.

[0029] Specifically, in this embodiment, the rack 150 is slidably matched with the box body 110, that is, the first slide 113 and the second slider 114 are arranged on the inner side of the box body 110. The first slide 113 and the second slider 114 are arranged on the inner side of the box body 110, and the box cover 120 does not need to be provided with a matching structure with the rack 150, so that the loading and unloading of the box cover 120 is easier. When the box cover 120 is removed, the sliding matching relationship between the rack 150 and the drive box will not be released, and the rack 150 and the drive assembly can be observed and repaired conveniently. In this embodiment, the first slide 113 and the second slider 114 are arranged at the bottom of the box body 110, and the two are arranged at intervals on the sliding path of the rack 150, and the first slider 152 and the second slide 154 are arranged at intervals in the length direction of the rack 150. The first slider 152 and the second slider 114 are both cylindrical, and in other embodiments, T-shaped or dovetail-shaped sliders can also be used to make it difficult for the slider to escape from the slide. It should be understood that in other embodiments of the present application, the rack 150 may also cooperate with the box cover 120 in the form of a slide groove and a slider.

[0030] Specifically in this embodiment, the drive box has a gear chamber 111 and a rack chamber 112 that are interconnected, the gear 140 is accommodated in the gear chamber 111, the rack 150 is accommodated in the rack chamber 112, and the gear 140 and the rack 150 are meshed at the connection point between the gear chamber 111 and the rack chamber 112. The inner side wall of the gear chamber 111 can be a major arc or a minor arc, and the radius of curvature is slightly larger than the radius of the gear 140, which can better protect the gear 140 without affecting the rotation of the gear 140. The rack chamber 112 is in a bar shape as a whole, and an opening is provided at one end for the rack 150 to extend out. The gear chamber 111 and the rack chamber 112 are separately provided, which can better protect the gear 140 and the rack 150, and the gear chamber 111 and the rack chamber 112 can be set according to the respective sizes of the gear 140 and the rack 150, which is conducive to improving the utilization rate of the drive box space and reducing redundant space. Of course, in other embodiments of the present application, the overall shape of the drive box may be changed, and the gear cavity 111 and the rack cavity 112 may not be separately provided, but a large cavity may be used to accommodate the gear 140 and the rack 150.

[0031] In this embodiment, a bayonet 156 is provided at one end of the rack 150 extending out of the drive box, and the rack 150 can be rotatably connected to the panel 200 through the bayonet 156. In this embodiment, the panel 200 has a connecting portion 210, which protrudes from the inner surface of the panel 200, and the connecting portion 210 has an outer arc surface. The inner side of the bayonet 156 has an inner arc surface that cooperates with the connecting portion 210, so that the two can be relatively rotated. The rack 150 is rotatably connected to the panel 200 through the bayonet 156, so that when the panel 200 is pushed to move, the panel 200 can also be allowed to rotate to a certain extent, which can meet some situations where the panel 200 needs to be flipped.

[0032] The air conditioner (not shown) provided in the embodiment of the present application comprises a panel 200 and the panel driving mechanism 100 provided in the above embodiment of the present application, and one end of the rack 150 extending out of the driving box is rotatably connected to the panel 200. Figure 1 In the embodiment shown, the panel 200 can be connected to the connection base 300 through a slide bar (not shown in the figure), so that the panel 200 can slide up and down relative to the connection base 300, and can also rotate to a certain extent relative to the connection base 300. The connection base 300 and the drive box remain relatively fixed. In this way, the movement mode of the panel 200 can be up and down movement and can be turned to a certain extent.

[0033] In summary, the panel driving mechanism provided in the embodiment of the present application includes a driving box, a group moving component and a rack connected to the driving component in a transmission manner. One end of the rack is located in the driving box and slidably cooperates with the driving box, and the other end protrudes out of the driving box and is connected to the panel. A first slider is provided on the rack, and the driving box is provided with a first slide groove that cooperates with the first slider. A second slider is also provided on the driving box, and a second slide groove that cooperates with the second slider is provided on the rack. Therefore, the two slide grooves are respectively located on the driving box and the rack, and the two sliders are also respectively located on the driving box and the rack. Such a structure is conducive to the stability of the rack when it moves, and thus also improves the stability of the panel opening and closing movement. Since the air conditioner adopts the above-mentioned panel driving mechanism, the opening and closing movement of its panel has better stability.

[0034] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the protection scope of the present application shall be subject to the scope defined by the claims.
