These designs consist of multiple modules, including a compressor module, a heat exchanger module, an internal fan module, and a return air box module. These modules are stacked to create a complete airflow system. Furthermore, depending on how the modules are stacked, different airflow configurations, such as top and bottom airflow, can be achieved. This allows for flexible and convenient installation of the air conditioner's indoor unit.

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] Please refer to Figures 1 to 13The present invention provides a locking device for connecting two adjacent modules 1 of an air-conditioning unit, each module 1 having a mounting shell 100, and the locking device comprising: a first locking component 11, the first locking component 11 being used to be set on the mounting shell 100 of one module 1, the first locking component 11 having a locking protrusion 110; a second locking component 21, the second locking component 21 being used to be set on the mounting shell 100 of the other module 1, the second locking component 21 having a locking groove 210, and the locking groove 210 cooperates with the locking protrusion 110; wherein the position of the first locking component 11 and / or the second locking component 21 is adjustable, so that by adjusting the position of the first locking component 11 and / or the second locking component 21, the locking device has a locking position in which the locking groove 210 and the locking protrusion 110 are engaged with each other and a release position in which the locking groove 210 is separated from the locking protrusion 110. Through the above-mentioned arrangement, the movement of the first locking part 11 and / or the second locking part 21 makes it easy to disassemble and assemble the two modules 1, and the mutual cooperation between the locking protrusion of the first locking part and the locking groove of the second locking part can improve the connection stability between the two modules.

[0043] In one embodiment of the present application, the first locking member 11 moves toward the second locking member 21 so that the locking protrusion is located in the locking groove of the second locking member 21 .

[0044] In order to improve the smoothness of locking between the first locking part and the second locking part, the locking protrusion 110 has a curved side wall surface 1101, and the second locking part 21 includes a locking rod 211, which is curved to form a locking groove 210. The position of the locking rod 211 is adjustable so that the locking groove 210 and the curved side wall surface 1101 of the locking protrusion 110 can be limitedly matched by adjusting the position of the locking rod 211, so that the second locking part 21 is in a locked position.

[0045] Specifically, the locking protrusion 110 has multiple curved side wall surfaces 1101, and the second locking component 21 includes multiple locking rods 211. The multiple locking rods 211 and the multiple curved side wall surfaces 1101 are arranged in a one-to-one correspondence. In this way, the stability of the connection between the first locking component and the second locking component can be further improved, thereby further improving the stability of the connection between the two modules 1.

[0046] In another embodiment of the present application, the second locking member 21 is movably provided. To achieve the movement of the second locking member 21, the second locking member 21 includes: a connecting shaft 22 for mounting on the mounting housing 100; a locking rod 211 having a slide groove 2110; the connecting shaft 22 passing through the slide groove 2110; and the slide groove 2110 extending along a predetermined trajectory, so that the locking rod 211 moves along the predetermined trajectory, causing the locking groove of the second locking member 21 to move to a locked position engaging with the locking protrusion or a released position separating from the locking protrusion. The predetermined trajectory is the extension direction of the locking rod 211.

[0047] Specifically, the second locking component 21 includes: a first elastic component 23, the first elastic component 23 is arranged in the slide groove 2110, one end of the first elastic component 23 is connected to the inner wall of the slide groove 2110, and the other end of the first elastic component 23 is connected to the connecting shaft 22. In this way, when the second locking component 21 moves to the locking position, the first elastic component 23 is compressed. When the second locking component 21 needs to move to the release position, the elastic force of the first elastic component 23 causes the first elastic component 23 to be released, thereby allowing the second locking component 21 to return to the release position.

[0048] Specifically, the first elastic member 23 is a first spring; the locking rod 211 is movably arranged relative to the connecting shaft 22 along the extension direction of the sliding groove 2110, and the locking rod 211 rotates around the axial direction of the connecting shaft 22.

[0049] In order to adjust the position of the second locking component 21, the locking device of the present application also includes: a transmission component 30, at least part of the transmission component 30 is movably arranged on the first locking component 11, and at least part of the transmission component 30 is connected to the second locking component 21 to drive the second locking component 21 to move through the movement of the transmission component 30.

[0050] Specifically, the transmission assembly 30 includes: a transmission rod 31, which is movably arranged on the first locking part 11; a telescopic structure 32, which is located between the first locking part 11 and the second locking part 21. When the second locking part 21 is in a released position, part of the telescopic structure 32 abuts against the end of the second locking part 21 away from the transmission rod 31; at least part of the telescopic structure 32 is telescopically arranged so that when the transmission rod 31 passes through the locking protrusion 110 of the first locking part 11 and abuts against the telescopic structure 32, the telescopic structure 32 retracts so that the telescopic structure 32 is pressed against the inner wall of the locking groove 210 to drive the second locking part 21 to move.

[0051] During the specific implementation of the transmission assembly 30 of the present application, when the second locking part 21 is in the released position, the transmission rod 31 is separated from the telescopic structure 32, and part of the telescopic structure 32 abuts against the end of the second locking part 21 away from the transmission rod 31. When the transmission rod 31 moves toward the telescopic structure 32 until the transmission rod 31 contacts the telescopic structure 32, the telescopic structure 32 has a tendency to move toward the direction close to the second locking part 21 through the transmission rod 31. At this time, the telescopic structure 32 is pressed on the inner wall of the locking groove 210, and the telescopic structure 32 is pressed on the end of the second locking part 21 close to the transmission rod 31, so that the end of the second locking part 21 close to the transmission rod 31 and the locking groove are limitedly matched with the locking protrusion.

[0052] Specifically, the telescopic structure 32 includes a first telescopic plate 321 and a second telescopic plate 322, the first telescopic plate 321 being slidably connected to the first telescopic plate 321. The second telescopic plate 322 has an abutting slope 3220 on the end away from the first telescopic plate 321. When the second locking member 21 is in the released position, the abutting slope 3220 abuts against the end of the second locking member 21 away from the transmission rod 31. The provision of the abutting slope 3220 provides a force component along the direction of the first and second telescopic plates 321 and 322, thereby enabling the second telescopic plate 322 to move along the direction of the first and second telescopic plates 321 and 322 when the transmission rod presses against the second telescopic plate 322.

[0053] Specifically, a preset angle is formed between the contact inclined surface 3220 and the horizontal plane; the horizontal plane is the plane where the first telescopic plate 321 is located.

[0054] In an embodiment of the present application, the second locking component 21 includes two locking rods 211, both locking rods 211 have locking grooves 210, and curved side walls 1101 are provided on both sides of the locking protrusion 110.

The two second telescopic plates 322 are arranged in a one-to-one correspondence with the two locking rods 211; the telescopic structure 32 also includes a second elastic member 323, which is arranged between the two second telescopic plates 322, so that when the two second telescopic plates 322 approach each other, the two second telescopic plates 322 compress the two ends of the second elastic member 323. By providing two locking rods 211 and two curved side wall surfaces 1101, the connection stability between the first locking component 11 and the second locking component 21 can be further improved, and by providing two second telescopic plates 322, the movement of the two locking rods 211 can be controlled at the same time. Through the second elastic member 323, when the two locking rods 211 need to move from the locking position to the release position, the two second telescopic plates 322 can be reset at the same time.

[0055] Specifically, the second elastic member 323 is a second spring; the locking protrusion 110 has a communication channel 111 for the transmission assembly 30 to pass through, and at least a portion of the transmission assembly 30 passes through the communication channel 111.

[0056] In order to realize automatic control of the movement of the second locking component 21 , the locking device further comprises: a driving component, which is mounted on the mounting housing 100 of the module 1 and is drivingly connected to the transmission rod 31 to drive the transmission rod 31 to move.

Through the above-mentioned setting, the locking device can be divided into a first locking component 10 and a second locking component 20. The first locking component 10 includes a first locking shell 12 and a first locking part 11. The second locking component 20 includes a second locking shell 24, a second locking part 21, a connecting shaft 22 and a first elastic part 23. In this way, the locking device is divided into two modules to realize the modular setting of the locking device. Through the protection of the first locking shell and the second locking shell, the internal locking protrusion and locking groove can be prevented from being affected by the external environment.

[0059] Specifically, the first locking housing 12 has two installation walls spaced apart along its thickness direction. There are two locking protrusions 110 , which are respectively disposed on the two installation walls. The communication channel 111 is located between the two locking protrusions 110 .
