Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, for example, to an air duct docking assembly and an air conditioner. Background Art

[0002] With the advancement of technology, air conditioner master units have gradually become part of people's lives. These units consist of a master unit and a slave unit, and the slave unit can enter and exit the master unit's cabin, allowing it to be independently moved to any location in the room.

[0003] Related art discloses a dual-unit air conditioner, where the sub-unit is equipped with an air outlet and the main unit has an air guide hood inside its cabin. After the sub-unit enters the cabin, when the air ducts of the sub-unit and the main unit need to be connected, the user needs to manually assemble the docking structure of the air guide hood and the air outlet.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The operation of manually assembling the docking structure is relatively complicated, resulting in low docking efficiency.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiments of the present disclosure provide an air duct docking assembly and an air conditioner, which solve the problem of low efficiency of manual docking of air guide covers.

[0009] In some embodiments, the air duct docking assembly includes:

[0010] An air guide cover, the first end of which is retractable and provided with a docking inlet, and the second end of which is provided with a docking outlet;

[0011] A filter structure is provided at the docking inlet and connected thereto;

[0012] The telescopic structure has a fixed end connected to the air guide cover and a telescopic end connected to the filter structure; and when the telescopic structure is extended or retracted, the first end of the air guide cover is driven to extend or retract synchronously to facilitate docking with external equipment.

[0013] In some embodiments, the air conditioner includes the air duct docking assembly.

[0014] The air duct docking assembly and air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0015] When an external device, such as an air conditioner sub-unit, requires air guidance, the telescopic structure extends the first end of the air guide hood, allowing the docking inlet to mate with the external device. Air from the external device then enters the air guide hood through the docking inlet and is directed out through the docking outlet. When the external device no longer requires air guidance, the telescopic structure retracts the first end of the air guide hood, disengaging the docking inlet from the external device. This allows for quick and efficient docking by simply controlling the telescopic structure's extension and retraction, eliminating the need for complex manual docking and installation procedures, significantly improving docking efficiency.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0046] Combine Figure 1-4As shown, the first embodiment of the present application provides an air duct docking assembly, comprising an air scoop 100, a filter structure 130, and a telescopic structure. The first end of the air scoop 100 is telescopic and has a docking inlet 101, while the second end of the air scoop 100 has a docking outlet 102. The filter structure 130 is disposed at and connected to the docking inlet 101. The fixed end of the telescopic structure is connected to the air scoop 100, while the telescopic end of the telescopic structure is connected to the filter structure 130. Furthermore, when the telescopic structure is extended or retracted, the first end of the air scoop 100 is synchronously extended or retracted to facilitate docking with external equipment.

[0047] In this embodiment, when the telescopic end of the telescopic structure extends or retracts, the telescopic end drives the filter structure 130 to move, and the filter structure 130 drives the first end of the air guide cover 100 to extend or retract synchronously. In the case where the external device needs to guide air, the telescopic structure is used to drive the first end of the air guide cover 100 to extend, so that the docking inlet 101 is connected to the external device. At this time, the air of the external device enters the air guide cover 100 through the docking inlet 101 and is guided out by the docking outlet 102. In the case where the external device does not need to guide air, the telescopic structure is used to drive the first end of the air guide cover 100 to retract, so that the docking inlet 101 is separated from the external device. In this way, quick and effective docking can be achieved by simply controlling the telescopic state of the telescopic structure, without the need for complicated manual docking and installation operations, which effectively improves the docking efficiency.

[0048] Alternatively, as Figure 1 As shown, the first end of the air scoop 100 is configured as a pleated skirt 110 , and when the pleated skirt 110 is stretched, the air scoop 100 extends, and when the pleated skirt 110 is compressed, the air scoop 100 retracts.

[0049] In this embodiment, the pleated skirt 110 is made of a resilient material, such as rubber or plastic. This material can withstand frequent expansion and contraction without damage, thereby improving the durability of the air scoop 100. Thus, the pleated skirt 110 allows the air scoop 100 to achieve a wide expansion and contraction range within a relatively small space, thereby saving space.

[0050] Alternatively, as Figure 2 As shown, the filter structure 130 covers the docking inlet 101, and the telescopic end of the telescopic structure is connected to the center of the filter structure 130. This helps to evenly distribute the force generated by the telescopic structure to the filter structure 130, preventing the filter structure 130 from deforming during the telescopic process, thereby ensuring the stability of the filter structure 130.

[0051] Alternatively, as Figure 3 As shown, a mounting plate 131 is provided at the center of the filter structure 130 , and the telescopic end of the telescopic structure is connected to the mounting plate 131 .

[0052] In this embodiment, the center of the filter structure 130 is provided with a mounting plate 131. The mounting plate 131 is constructed as a circular plate, and the mounting plate 131 is connected to the edge by a grid around the perimeter. In this way, the mounting plate 131 provides a mounting space for the telescopic end and helps reduce stress concentration.

[0053] Alternatively, as Figure 3 As shown, the telescopic structure includes an electric push rod 200, which includes a push rod seat 210 and a telescopic rod 220, and the telescopic rod 220 is telescopically arranged in the push rod seat 210; wherein, the push rod seat 210 is connected to the air guide cover 100 as a fixed end, and the telescopic rod 220 is connected to the filter structure 130 as a telescopic end; or, the telescopic rod 220 is connected to the air guide cover 100 as a fixed end, and the push rod seat 210 is connected to the filter structure 130 as a telescopic end.

[0054] In this embodiment, due to the use of an electric push rod 200, the telescopic adjustment process can be achieved through simple electronic control. Here, the telescopic end refers to the end that can move relative to the fixed end. Depending on the installation method of the push rod base 210 and the telescopic rod 220, either end can serve as the fixed end, and the other end can serve as the telescopic end. For example, the end of the telescopic rod 220 is connected to the second end of the air scoop 100, and the push rod base 210 is connected to the filter structure 130. In this case, when the telescopic rod 220 is extended or retracted, since the end of the telescopic rod 220 is fixed, the filter structure 130 can only be driven by the push rod base 210.

[0055] Alternatively, as Figure 4 As shown, a turnover plate 120 is provided at the docking outlet 102, and one side of the turnover plate 120 is hinged to the docking outlet 102 to cover or avoid the docking outlet 102 by turnover. In this way, the air circulation of the docking outlet 102 can be controlled by the turnover plate 120.

[0056] Optionally, the docking outlet 102 is arranged upward; wherein, the flip plate 120 can be opened by the wind pressure in the wind guide cover 100 to avoid the docking outlet 102; or, the flip plate 120 automatically flips under the action of its own weight to cover the docking outlet 102.

[0057] In this embodiment, because the flip plate 120 has its own gravity, when the wind pressure within the air scoop 100 is less than the gravity, the flip plate 120 automatically flips downward, thereby covering the docking outlet 102 and blocking air outflow. When the wind pressure within the air scoop 100 is greater than the gravity, the flip plate 120 flips upward, thereby avoiding the docking outlet 102 and allowing air to flow out.

[0058] An embodiment of the present disclosure further provides an air conditioner, comprising the air duct docking assembly described in any of the above embodiments.

[0059] Alternatively, as Figure 5 As shown, the air conditioner consists of a main unit 500 and a sub-unit 510, wherein the main unit 500 is provided with a cabin 501; and the air duct docking assembly is arranged in the cabin 501, and its docking outlet 102 is connected to the air duct of the main unit 500; the sub-unit 510 is arranged in the cabin 501, and the sub-unit 510 is provided with an air outlet 511; and the extension direction of the air guide cover 100 is toward the air outlet 511, so that the docking inlet 101 is connected to the air outlet 511.

[0060] In this embodiment, the air duct docking assembly is used to dock and connect the air duct and the air outlet 511 of the main machine 500. After the sub-machine 510 moves into the cabin 501, if there is a need for air guide, the air guide cover 100 is extended toward the air outlet 511 through the telescopic structure, and then the docking inlet 101 is connected to the air outlet 511. At this time, the air generated by the sub-machine 510 flows into the air duct of the main machine 500 from the air outlet 511, the docking inlet 101, and the docking outlet 102 in sequence. When the sub-machine 510 is ready to leave the cabin 501, the air guide cover 100 is retracted through the telescopic structure, so that the sub-machine 510 and the docking inlet 101 are separated, so that the sub-machine 510 can be moved out easily.

[0061] Alternatively, as Figure 4 As shown, a docking groove 512 is provided on the periphery of the air outlet 511 , and the docking groove 512 corresponds to the side wall of the docking inlet 101 ; when the air guide cover 100 is extended to the docking position, the side wall of the docking inlet 101 is inserted into the docking groove 512 .

[0062] In this embodiment, the plug-in design of the docking inlet 101 and the docking groove 512 effectively reduces the risk of air leakage and improves the sealing performance of the air duct docking assembly. In addition, it helps to make the air guide cover 100 more stable in the extended state and less likely to shake or shift.

[0063] Combine Figure 6-9 As shown, the second embodiment of the present application provides an air duct docking assembly, including an air guide cover 100 and a flexible channel 300. Figure 2 As shown, the first end of the air guide cover 100 is provided with a docking inlet 101, and the second end thereof is provided with a docking outlet 102; the channel outlet 302 of the flexible channel 300 is connected to the docking inlet 101, and its channel inlet 301 is used for docking external equipment; wherein, the first side of the channel outlet 302 is hinged to the docking inlet 101, and the second side thereof is fixedly connected to the docking inlet 101; and, the second side of the channel inlet 301 corresponds to the second side of the channel outlet 302, and the second side of the channel inlet 301 can rotate around the first side of the channel outlet 302 to drive the flexible channel 300 to extend and retract.

[0064] In this embodiment, the flexible channel 300 serves as an extension of the air guide cover 100 and can be retracted and extended by rotating. When the external device needs to guide air, the second side of the channel inlet 301 is rotated around the first side of the channel outlet 302 to extend the flexible channel 300, thereby making the channel inlet 301 connect with the external device. At this time, the air of the external device enters the air guide cover 100 through the channel inlet 301, the channel outlet 302, and the docking inlet 101 in sequence, and is guided out by the docking outlet 102. When the external device does not need to guide air, the second side of the channel inlet 301 is rotated around the first side of the channel outlet 302 to retract the flexible channel 300, thereby making the docking inlet 101 disengaged from the external device. In this way, it is only necessary to adjust the rotation state of the flexible channel 300 to achieve quick and effective docking, without the need for complex manual docking and installation operations, thereby effectively improving the docking efficiency.

[0065] Optionally, a filter structure 130 is provided at the channel inlet 301; Figure 7 As shown, the first side of the channel inlet 301 , the first side of the channel outlet 302 , and the first side of the filter structure 130 correspond to and overlap as one, and the second side of the channel inlet 301 is connected to the first side of the channel outlet 302 through the filter structure 130 .

[0066] In this embodiment, the first side of the channel inlet 301, the first side of the channel outlet 302, and the first side of the filter structure 130 are integrally formed, and the second side of the channel inlet 301 is connected to the first side of the channel outlet 302 via the filter structure 130. When the first side of the channel outlet 302 rotates, the second side of the channel inlet 301 is driven to rotate synchronously via the filter structure 130, and the rotation and extension form a fan shape.

[0067] Optionally, the first side of the channel outlet 302 is hinged to the docking inlet 101 via a rotating shaft 310, and a touch panel 320 is provided on the rotating shaft 310, such as Figure 7 As shown, the touch panel 320 is moved by an external force F to drive the rotating shaft 310 to rotate in a first direction. At this time, the rotating shaft 310 drives the second side of the channel inlet 301 to rotate through the filter structure 130 to extend the flexible channel 300.

[0068] In this embodiment, the touch panel 320 serves as a rotation handle for the rotating shaft 310. When an external force is applied to the touch panel 320, the rotating shaft 310 is driven to rotate. Furthermore, when the rotating shaft 310 rotates in a first direction, the rotating shaft 310 drives the second side of the channel inlet 301 to rotate through the filter structure 130, thereby extending the flexible channel 300.

[0069] Optionally, a torsion spring is further provided on the rotating shaft 310, and after the external force acting on the touch panel 320 disappears, the torsion spring can drive the rotating shaft 310 to rotate in a second direction to retract the flexible channel 300; wherein the second direction is opposite to the first direction.

[0070] In this embodiment, when the flexible channel 300 is in the fully retracted position, the torsion spring remains in its initial, unloaded state. When an external force acts on the touch panel 320, causing the rotating shaft 310 to rotate in a first direction, the torsion spring enters a stored energy state. When the external force disappears, the stored elastic force in the torsion spring is released, driving the rotating shaft 310 to rotate in a second direction. At this point, the rotating shaft 310, through the filter structure 130, drives the second side of the channel inlet 301 to rotate, causing the flexible channel 300 to retract.

[0071] Alternatively, as Figure 7 As shown, when the air duct docking assembly is placed vertically, the height of the first side of the channel outlet 302 is lower than the height of the second side of the channel outlet 302; and, when the second side of the channel inlet 301 is rotated to the docking position, it is the same height as the first side of the channel outlet 302.

[0072] In this embodiment, since the first side of the channel outlet 302 coincides with the first side of the channel inlet 301, in the docking position, both sides of the channel inlet 301 can be considered to be at the same height. This allows the channel inlet 301 to be relatively flush, eliminating the need for additional adjustment or calibration, and facilitating docking with external equipment.

[0073] Alternatively, as Figure 8 As shown, a turnover plate 120 is provided at the docking outlet 102, and one side of the turnover plate 120 is hinged to the docking outlet 102 to cover or avoid the docking outlet 102 by turnover. In this way, the air circulation of the docking outlet 102 can be controlled by the turnover plate 120.

[0074] An embodiment of the present disclosure further provides an air conditioner, comprising the air duct docking assembly described in any of the above embodiments.

[0075] Optionally, the air conditioner is composed of a mother unit 500 and a sub-unit 510, wherein the mother unit 500 is provided with a cabin 501; and the air duct docking assembly is arranged in the cabin 501, and its docking outlet 102 is connected to the air duct of the mother unit 500; the sub-unit 510 is arranged in the cabin 501, and the sub-unit 510 is provided with an air outlet 511; and the telescopic direction of the flexible channel 300 is toward the air outlet 511, so that the channel inlet 301 is connected to the air outlet 511.

[0076] In this embodiment, if Figure 5As shown, the air duct docking assembly is used to dock the air duct and air outlet 511 of the main machine 500. When the sub-machine 510 moves into the cabin 501, if there is a need for air guide, the flexible channel 300 is extended, and then the channel inlet 301 is connected to the air outlet 511. Preferably, as Figure 8 As shown, the touch panel 320 is located on the moving track of the slave 510. Figure 9 As shown, after the slave unit 510 is moved into position, it pushes against the touch plate 320 to rotate the shaft 310, thereby extending the flexible channel 300 and completing the docking. At this point, air generated by the slave unit 510 flows sequentially through the air outlet 511, the channel inlet 301, the channel outlet 302, the docking inlet 101, and the docking outlet 102 into the air duct of the base unit 500. When the slave unit 510 leaves the cabin 501, it disengages from the touch plate 320, and the flexible channel 300 retracts under the action of the torsion spring. At this point, the slave unit 510 and the channel inlet 301 are separated, facilitating its removal.

[0077] Optionally, a docking groove 512 is provided on the periphery of the air outlet 511 , and the docking groove 512 corresponds to the side wall of the channel inlet 301 ; when the air guide cover 100 is extended to the docking position, the side wall of the channel inlet 301 is inserted into the docking groove 512 .

[0078] In this embodiment, the plug-in design of the channel inlet 301 and the docking groove 512 effectively reduces the risk of air leakage and improves the sealing performance of the air duct docking assembly. It also helps to make the flexible channel 300 more stable in the extended state and less likely to shake or deflect due to external factors.

[0079] Combine Figure 10-14 As shown, the third embodiment of the present application provides a chassis assembly, including a chassis body 400, a lifting structure, and a drive structure. The chassis body 400 includes a liftable load plate 401; the lifting structure is disposed below the load plate 401 and includes a rotating member 410 and a lifting member 420; the lifting member 420 is connected to the rotating member 410 to rotate synchronously therewith, and the load plate 401 is located on the rotation trajectory of the lifting member 420; the lifting member 420 has a lifting position, which corresponds to the lifting member 420 contacting the load plate 401 to raise the load plate 401; and the drive structure is used to drive the rotating member 410 to rotate.

[0080] In this embodiment, the support plate 401 is used to place external equipment. When the drive structure drives the rotating member 410 to rotate, the rotating member 410 drives the lifting member 420 to rotate. When the lifting member 420 rotates to the lifting position, the lifting member 420 contacts the support plate 401 upward, thereby raising the support plate 401 and the external equipment. For example, the external equipment is an air conditioner sub-unit 510, and above the sub-unit 510 is an air scoop. The support plate can automatically raise the sub-unit 510, thereby facilitating the subsequent docking of the sub-unit 510 with the air scoop.

[0081] Alternatively, as Figure 11 As shown, the chassis body 400 further includes a bottom plate 402 , which is disposed below the bearing plate 401 , and an upper surface of the bottom plate 402 is used for mounting a lifting structure and / or a driving structure.

[0082] In this embodiment, the upper surface of the base plate 402 is provided with a mounting slot, and the supporting plate 401 covers the notch of the mounting slot. The lifting structure and / or the driving structure are both disposed within the mounting slot. This makes the entire chassis assembly more compact and reduces space usage.

[0083] Optionally, the rotating member 410 includes a rotating rod, which is horizontally mounted on the base plate 402, and one or more lifting members 420 are fixed on the rotating rod; and in the case of multiple lifting members 420, the projections of all lifting members 420 along the axial direction of the rotating rod coincide.

[0084] In this embodiment, the rotation of the rotating rod drives the lifting members 420 to rotate synchronously. The upper surface of the base plate 402 is provided with two opposing support arms, with the ends of the rotating rod horizontally mounted on each of the two support arms. Furthermore, when multiple lifting members 420 are evenly arranged, since the projections of all lifting members 420 along the axial direction of the rotating rod overlap, all lifting members 420 will be in the same position after synchronous rotation. This allows all lifting members 420 to rotate simultaneously to the lifting position, which helps to more evenly distribute the force on the load-bearing plate 401 and thus improves the stability of the chassis assembly.

[0085] Optionally, the driving structure includes a connecting plate 440 and an electric push rod 200. Figure 12 As shown, the first end of the connecting plate 440 is fixedly connected to the rotating rod; the electric push rod 200 includes a push rod seat 210 and a telescopic rod 220, and the telescopic rod 220 is telescopically arranged in the push rod seat 210; wherein, the push rod seat 210 is fixed on the base plate 402, the telescopic rod 220 is connected to the second end of the connecting plate 440, and when the telescopic rod 220 is extended or retracted, it pushes the connecting plate 440 to move, and then the connecting plate 440 drives the rotating rod to rotate.

[0086] In this embodiment, the electric push rod 200 moves the connecting plate 440 by extending and retracting the telescopic rod 220, which in turn drives the rotating rod to rotate, thereby achieving the lifting and lowering control of the support plate 401. Preferably, the connecting plate 440 is located in the middle of the rotating rod, and the telescopic rod 220 extends and retracts perpendicular to the axial direction of the rotating rod. In this way, the extension and retraction force of the electric push rod 200 acting on the rotating rod can make the rotating rod more stable during rotation, reducing shaking or deviation caused by uneven force.

[0087] Alternatively, as Figure 12 As shown, the second end of the connecting plate 440 is provided with a snap-on notch 441, and the telescopic rod 220 is provided with a snap ring 442, which snaps into the snap-on notch 441. Thus, the snap-on connection between the snap ring 442 and the snap-on notch 441 ensures a secure connection between the telescopic rod 220 and the connecting plate 440. Furthermore, the installation and removal of the telescopic rod 220 and the connecting plate 440 is relatively simple and quick.

[0088] Alternatively, as Figure 13 As shown, the lifting member 420 has a relief position, which corresponds to the lifting member 420 being out of contact with the supporting plate 401, allowing the supporting plate 401 to descend. When the lifting member 420 is in the relief position, the supporting plate 401 loses its upward contact force, and the supporting plate 401 descends to its initial position.

[0089] Optionally, a limiting member 430 is provided on the lower surface of the supporting plate 401 , and the limiting member 430 corresponds to the lifting member 420 and is used to limit the lifting member 420 in the lifting position.

[0090] In this embodiment, the limiting member 430 includes a limiting plate, which is formed by extending downward from the lower plate surface of the supporting plate 401. Figure 14 As shown, the driving structure drives the lifting member 420 to rotate forward to the lifting position. At this time, the limit plate prevents the lifting member 420 from continuing to rotate forward, thereby ensuring the stability of the lifting member 420 in the lifting position.

[0091] Alternatively, as Figure 11 As shown, the upper surface of the base plate 402 is provided with a guide column 450, which extends along the lifting direction of the supporting plate 401; the lower surface of the supporting plate 401 is provided with a guide cylinder 451, which corresponds to the guide column 450 and is inserted into the guide column 450 to guide the lifting and lowering of the supporting plate 401.

[0092] In this embodiment, through the cooperation of the guide post 450 and the guide cylinder 451, the supporting plate 401 can maintain a stable trajectory and posture during the lifting process, reducing the risk of deviation or tilt. In addition, the contact area between the guide post 450 and the guide cylinder 451 is large, providing stable support, making the lifting process smoother. Preferably, a guide post 450 is respectively provided at the four corners of the mounting groove of the base plate 402, and four corresponding guide cylinders 451 are provided on the lower plate surface of the supporting plate 401, which is conducive to further improving stability. Here, the guide post 450 can also be provided on the lower plate surface of the supporting plate 401, and the guide cylinder 451 is correspondingly provided on the upper plate surface of the base plate 402.

[0093] An embodiment of the present disclosure further provides an air conditioner, comprising the chassis assembly described in any of the above embodiments.

[0094] Optionally, the air conditioner is composed of a mother unit 500 and a sub-unit 510, wherein the mother unit 500 is provided with a cabin 501; and the bottom of the cabin 501 is provided with the chassis assembly, and the top of the cabin 501 is provided with an air duct docking assembly; the sub-unit 510 is arranged in the cabin 501 and is located on the supporting plate 401, and an air outlet 511 is provided on the top; and when the lifting member 420 is rotated to the lifting position, the supporting plate 401 drives the sub-unit 510 to rise, so that the air outlet 511 of the sub-unit 510 is connected to the air duct docking assembly.

[0095] In this embodiment, the air duct docking assembly is used to dock the air duct and the air outlet 511 that are connected to the main machine 500. When the sub-machine 510 is moved into the cabin 501 and is located on the supporting plate 401, if there is a need for air guide, the lifting member 420 is rotated to the lifting position. At this time, the supporting plate 401 rises, thereby driving the sub-machine 510 to rise, so that the air outlet 511 is docked with the air duct docking assembly. When the sub-machine 510 is ready to leave the cabin 501, the lifting member 420 is rotated to the avoidance position. At this time, the supporting plate 401 descends, thereby driving the sub-machine 510 to descend, so that the air outlet 511 is disengaged from the air duct docking assembly, so that the sub-machine 510 can be moved out. The air duct docking assembly can be the structure described in the first embodiment or the second embodiment, or it can be other structures, which are not specifically limited here.
