[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] Combination Figures 1 to 9 As shown, the embodiment of the present disclosure provides a door assembly, including: a frame 100, which is provided with an opening 110, and the frame 100 includes a first side 121 and a second side 122 extending vertically; a first door panel 210, which is rotatably arranged on the first side 121; a second door panel 220, which is rotatably arranged on the second side 122; a first telescopic mechanism 310, which is fixedly arranged on the inner side of the frame 100 and is rotatably connected to the first door panel 210, and when the first telescopic mechanism 310 is extended toward the outer side of the frame 100, , which can drive the first door panel 210 to rotate around the first side edge 121 to avoid the opening 110; the second telescopic mechanism 320 is fixedly arranged on the inner side of the frame 100 and is rotatably connected to the second door panel 220. When the second telescopic mechanism 320 is facing the outer side of the frame 100, it can drive the second door panel 220 to rotate around the first side end to avoid the opening 110; wherein, when the first telescopic mechanism 310 and the second telescopic mechanism 320 are both in the retracted state, the first door panel 210 and the second door panel 220 are docked and block the opening 110.

[0045] Optionally, the door assembly can be applied to an indoor unit of an air conditioner, wherein the indoor unit of the air conditioner includes a main housing 10, the interior of the main housing 10 defines a sub-accommodating cavity 101, and the main housing 10 includes a front panel 102. The frame 100 is formed on the front panel 102, that is, the front panel 102 can be the frame 100, so that the opening 110 is arranged corresponding to the sub-accommodating cavity 101, the inner side of the frame 100 faces the sub-accommodating cavity 101, and when the first door panel 210 and the second door panel 220 avoid the opening 110, the sub-accommodating cavity 101 is connected to the space outside the main housing 10.

[0046] Optionally, the first door panel 210 is rotatably arranged on the left side of the frame 100, and the second door panel 220 is rotatably arranged on the right side of the frame 100, and the first door panel 210 is controlled to be rotated open or closed by the first telescopic mechanism 310, and the second door panel 220 is controlled to be rotated open or closed by the second telescopic mechanism 320. Wherein, when the first telescopic mechanism 310 and the second telescopic mechanism 320 are both in the retracted state, the first door panel 210 and the second door panel 220 are docked and can block the opening 110, thereby closing the opening 110 to maintain the integrity and aesthetics of the appearance of the main body shell. By providing the shielding member for closing the opening 110 with the first door panel 210 and the second door panel 220 that can be opened or closed respectively, the space occupied by the first door panel 210 and the second door panel 220 when avoiding and opening the opening 110 can be reduced.

[0047] Optionally, the first telescopic mechanism 310 and the second telescopic mechanism 320 are linear telescopic mechanisms, and are both disposed on the inner side of the frame 100. In order to reduce the occupation of the sub-accommodating cavity 101 by the first telescopic mechanism 310 and the second telescopic mechanism 320, the first telescopic mechanism 310 and the second telescopic mechanism 320 extend along the depth direction of the main housing 10 (i.e., the direction from the front panel 102 to the back panel of the main housing 10). When the first telescopic mechanism 310 extends in a straight line toward the outside of the frame 100, it pushes the first door panel 210 to move. Since the first door panel 210 is rotatably connected to the first side edge 121 of the frame 100, the first door panel 210 can be rotated around the first side edge 121 to switch to a state toward the avoidance opening 110; similarly, when the second telescopic mechanism 320 extends in a straight line toward the outside of the frame 100, it pushes the second door panel 220 to move. Since the second door panel 220 is rotatably connected to the second side edge 122 of the frame 100, the second door panel 220 can be rotated around the second side edge 122 to switch to a state toward the avoidance opening 110, thereby enabling the opening 110 to be opened. At the same time, since the first telescopic mechanism 310 and the second telescopic mechanism 320 are linear telescopic mechanisms, the first door panel 210 can be rotated at most to a direction parallel to the extension of the first telescopic mechanism 310, that is, toward the front of the outside of the frame 100. Similarly, the second door panel 220 can be rotated at most to a direction parallel to the extension of the second telescopic mechanism 320, that is, toward the front of the outside of the frame 100. This can avoid occupying the space on the left and right sides of the air-conditioning indoor unit.

[0048] Optionally, in order to fully open the opening 110, the first telescopic mechanism 310 is arranged close to the first side 121, and the second telescopic mechanism 320 is arranged close to the second side 122, so as to avoid blocking the inner space of the frame 100 corresponding to the opening 110. When the door assembly is arranged in the indoor unit of the air conditioner, the space of the sub-accommodating cavity 101 can be avoided from being occupied.

[0049] As an implementation method that occupies the smallest space, the extension direction of the first telescopic mechanism 310 is perpendicular to the first door panel 210 , and the extension direction of the second telescopic mechanism 320 is also perpendicular to the second door panel 220 .

[0050] Optionally, the first telescopic mechanism 310 can be tilted from top to bottom and rotatably connected to the lower half of the first door panel 210; or, the first telescopic mechanism 310 can be tilted from bottom to top and rotatably connected to the upper half of the first door panel 210. Optionally, the first telescopic mechanism 310 can be tilted from top to bottom and rotatably connected to the lower half of the first door panel 210; or, the first telescopic mechanism 310 can be tilted from bottom to top and rotatably connected to the upper half of the first door panel 210. Wherein, when the first door panel 210 and the second door panel 220 are placed vertically, the midline extending along the horizontal plane is used as the dividing line, the upper half is located above the midline, and the lower half is located below the midline.

[0051] The door body assembly provided by the embodiment of the present disclosure can drive the rotation of the first door panel and the second door panel respectively through the first telescopic mechanism and the second telescopic mechanism arranged on the frame, so as to realize the opening or closing of the opening; when the first telescopic mechanism and the second telescopic mechanism are both in the contracted state, the first door panel and the second door panel are docked and can cover the opening to close the opening; by controlling the first telescopic mechanism to switch to the extended state, the first door panel can be driven to rotate around the first side edge and avoid opening the opening; by controlling the second telescopic mechanism to switch to the extended state, the second door panel can be driven to rotate around the second side edge and avoid opening the opening. In this way, the door body assembly can reduce the occupation of the external space when the first door panel and the second door panel are opened by being set as the structure of the first door panel and the second door panel; on the other hand, since the first door panel and the second door panel can be rotated to the direction parallel to the extension of the first telescopic mechanism and the second telescopic mechanism, the space on the left and right sides can be avoided, which is beneficial to the floor area.

[0052] Optionally, the door body assembly also includes a first hinge assembly 410 and a second hinge assembly 420; the first hinge assembly 410 includes a first rotating shaft 411, a first hinge 412 and a second hinge 413, wherein the first hinge 412 is fixedly arranged on the first door panel 210 and is sleeved on the first rotating shaft 411, and the second hinge 413 is correspondingly arranged on the first side panel and is sleeved on the first rotating shaft 411; the second hinge assembly 420 includes a second rotating shaft 421, a third hinge 422 and a fourth hinge 423, wherein the third hinge 422 is fixedly arranged on the second door panel 220 and is sleeved on the second rotating shaft 421, and the fourth hinge 423 is correspondingly arranged on the second side 122 and is sleeved on the second rotating shaft 421.

[0053] The first door panel 210 is rotatably connected to the frame 100 by the first hinge assembly 410, and the second door panel 220 is rotatably connected to the frame 100 by the second hinge assembly 420. The structure is relatively simple and easy to maintain, and is convenient for disassembly, cleaning and replacement. At the same time, the first hinge assembly 410 and the second hinge assembly 420 have high flexibility when rotating, which facilitates the rotation of the first door panel 210 and the second door panel 220 relative to the frame 100.

[0054] Optionally, a plurality of groups of first hinge assemblies 410 are arranged at intervals along the vertical direction of the first door panel 210 to improve the stability of the connection between the first door panel 210 and the first side edge 121 , thereby ensuring the overall rotation flexibility of the first door panel 210 .

[0055] The first hinge assembly 410 includes a first rotating shaft 411, a first hinge 412 and a second hinge 413; the first hinge 412 is fixedly disposed on the first door panel 210 and sleeved on the first rotating shaft 411, thereby realizing the installation and fixation of the first rotating shaft 411, and the second hinge 413 is correspondingly disposed on the first side edge 121 and sleeved on the first rotating shaft 411. When the first telescopic mechanism 310 is extended, the first door panel 210 is pushed to form a movement toward the outside of the frame 100 (the external environment of the host housing 10), so that the first door panel 210 drives the first rotating shaft 411 to rotate relative to the second hinge 413.

[0056] Optionally, a plurality of groups of second hinge assemblies 420 are arranged at intervals along the vertical direction of the second door panel 220 to improve the stability of the connection between the second door panel 220 and the second side edge 122 , thereby ensuring the overall rotation flexibility of the second door panel 220 .

[0057] The first hinge assembly 410 includes a second rotating shaft 421, a third hinge 422 and a fourth hinge 423; the third hinge 422 is fixedly disposed on the second door panel 220 and sleeved on the second rotating shaft 421, thereby realizing the installation and fixation of the second rotating shaft 421, and the fourth hinge 423 is correspondingly disposed on the second side and sleeved on the second rotating shaft 421. When the second telescopic assembly is extended, the second door panel 220 is pushed to move toward the outside of the frame 100 (the external environment of the host housing 10), so that the second door panel 220 drives the second rotating shaft 421 to rotate relative to the fourth hinge 423.

[0058] Optionally, the door body assembly also includes a first drive motor 510 and a second drive motor 520; the first drive motor 510 is a linear motor, fixedly connected to the frame 100, and the first drive motor 510 is used to drive the first telescopic mechanism 310 to contract or extend along a straight line; the second drive motor 520 is a linear motor, fixedly connected to the frame 100, and the second drive motor 520 is used to drive the second telescopic mechanism 320 to contract or extend along a straight line.

[0059] Optionally, the first drive motor 510 is preferably a linear motor, and the extension direction of the output shaft of the linear motor is set horizontally. In this way, the extension or contraction of the first telescopic mechanism 310 can be driven by the extension and contraction of the output shaft of the first drive motor 510, simplifying the motion trajectory control of the first telescopic mechanism 310.

[0060] Optionally, the second drive motor 520 is preferably a linear motor, and the extension direction of the output shaft of the linear motor is set horizontally. In this way, the extension or contraction of the second telescopic mechanism 320 can be driven by the extension and contraction of the output shaft of the second drive motor 520, simplifying the motion trajectory control of the first telescopic mechanism 310.

[0061] Optionally, the first telescopic mechanism 310 includes at least: a first telescopic rod 311, a first end of the first telescopic rod 311 is rotatably connected to the first door panel 210, and a second end of the first telescopic rod 311 is drivingly connected to the output shaft of the first drive motor 510; a second telescopic rod 312, which is slidably mounted on the first telescopic rod 311 and fixedly connected to the first drive motor 510.

[0062] By making the second end of the first telescopic rod 311 drive-connected with the output shaft of the first drive motor 510, the first telescopic rod 311 can be extended or retracted relative to the second telescopic rod 312 when the output shaft of the first drive motor 510 is extended or retracted, thereby realizing the extension or contraction of the first telescopic mechanism 310; at the same time, by making the first end of the first telescopic rod 311 rotationally connected with the first door panel 210, when the first telescopic mechanism 310 is extended or contracted to drive the first door panel 210 to rotate, the first door panel 210 can be rotated relative to the first telescopic mechanism 310, thereby realizing the rotation of the first door panel 210 and ensuring the flexibility of the rotation of the first door panel 210. By the sleeve connection between the second telescopic rod 312 and the first telescopic rod 311, the stability of the first telescopic mechanism 310 along the straight line motion can be improved to a certain extent.

[0063] Optionally, a first limiting ring 211 is provided on the inner side of the first door panel 210, a first through hole 313 is opened at the first moving end of the first telescopic rod 311, and the first through hole 313 and the first limiting ring 211 are nested and connected with each other to realize the rotational connection between the first door panel 210 and the first telescopic mechanism 310.

[0064] The circumference of the first through hole 313 extends vertically. In this way, the first limit ring 211 can be rotated along the radial direction of the first through hole 313, thereby realizing the rotation of the first door panel 210 relative to the flow field of the first telescopic mechanism 310. The structure is simple, stable and has a low failure rate.

[0065] Optionally, the first through hole 313 is a circular hole, and the outer peripheral surface of the first through hole 313 close to the first limiting ring 211 is constructed as an arc, and the first limiting ring 211 is a circular ring, which is beneficial to reduce the friction between the two, help improve the flexibility of rotation, and extend the service life.

[0066] Optionally, the first telescopic mechanism 310 may also be a gear transmission mechanism, including a first gear, a first rack and a first rotary motor. The first rotary motor drives the first gear to rotate, and the first gear drives the first rack to move out of or into the inner side of the frame 100 (i.e., the sub-accommodating cavity 101), thereby driving the rotation of the first door panel 210. Among them, a first through hole 313 is provided at one end of the first rack, and the first through hole 313 and the first limiting ring 211 are nested and connected with each other to achieve a rotation connection with the first door panel 210.

[0067] Optionally, the second telescopic mechanism 320 includes at least: a third telescopic rod 321, a first end of the third telescopic rod 321 is rotatably connected to the second door panel 220, and a second end of the third telescopic rod 321 is drivingly connected to the output shaft of the second drive motor 520; a fourth telescopic rod 322, which is slidably mounted on the third telescopic rod 321 and fixedly connected to the second drive motor 520.

[0068] By making the second end of the third telescopic rod 321 drive-connected with the output shaft of the second drive motor 520, the third telescopic rod 321 can be extended or retracted relative to the fourth telescopic rod 322 when the output shaft of the second drive motor 520 is extended or retracted, thereby realizing the extension or contraction of the second telescopic mechanism 320; at the same time, by making the first end of the third telescopic rod 321 rotationally connected with the second door panel 220, when the second telescopic mechanism 320 is extended or contracted to drive the second door panel 220 to rotate, the second door panel 220 can be rotated relative to the second telescopic mechanism 320, thereby realizing the rotation of the second door panel 220 and ensuring the flexibility of the rotation of the second door panel 220. By the sleeve connection between the fourth telescopic rod 322 and the third telescopic rod 321, the stability of the second telescopic mechanism 320 along the straight line motion can be improved to a certain extent.
