Description

Technical Field

[0001] This invention relates to the field of air conditioners, and more specifically, to a connection structure and an air conditioner. Background Technology

[0002] In traditional wall-mounted air conditioners, the air deflector is usually driven at the front of the air outlet to adjust the air delivery angle. Existing air conditioners usually adopt a double air deflector structure, which can better meet the requirements of cooling, where cold air blows upward and falls naturally, and the cold air does not blow on people, and heating, where warm air blows downward and falls quickly.

[0003] However, during the up-and-down sweeping process, the airflow organization changes at different positions due to the influence of the blowing air, resulting in uneven force on the air guide plate, causing it to vibrate and generate noise. In severe cases, the air guide plate may resonate with the shell or even detach, affecting its reliability. Summary of the Invention

[0004] The main objective of this invention is to provide a connection structure and an air conditioner to solve the problem of structural instability of the air guide plate in the prior art when guiding air.

The connecting structure also includes a drive motor, the output shaft of the drive motor is connected to the first connecting part, and the connecting rod is connected to the second connecting part.

[0011] Furthermore, a first connecting hole is provided on the first connecting part, and a second connecting hole is provided on the second connecting part. The extension direction of the first connecting hole and the extension direction of the second connecting hole both coincide with the rotation direction of the air guide plate. The output shaft of the drive motor is inserted into the first connecting hole, and a mounting shaft is provided on the connecting rod. The mounting shaft is inserted into the second connecting hole.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] See Figures 1 to 7The connection structure of this embodiment includes: an air guide plate 1, rotatably connected to the housing 10 of the air conditioner; and a connection assembly 2, which includes a connecting rod 22, one end of which is connected to the air guide plate 1, and the other end of which is provided with a connecting component 23. The connecting component 23 is rotatably connected to the connecting rod 22, and the connecting component 23 has a damping part 21. When the air guide plate 1 stops rotating, the damping part 21 abuts against the housing 10 to limit the position of the air guide plate 1. With the above arrangement, when the air guide plate 1 is working, in order to prevent the air guide plate from being subjected to large impact wind forces, the damping part 21 plays a buffering role, preventing the air guide plate from shaking or falling off due to the wind. At the same time, due to the effect of the damping part 21, the torque on the air guide plate 1 is reduced, thereby making the air guide plate 1 run more smoothly and solving the problem of structural instability of the air guide plate in the prior art when guiding air.

[0028] In the connection structure of this embodiment, see Figures 1 to 5 There are multiple damping parts 21, which are arranged around the rotation axis of the connecting member 23. In this way, the air guide plate 1 can be damped by the damping effect of the damping parts 21 when it is at different rotation angles.

[0029] See Figures 1 to 5 In the connection structure of this embodiment, the connection structure also includes a rack portion 3, which is disposed on the housing 10. The rack portion 3 is provided with a plurality of toothed grooves 31 for the damping portion 21 to be inserted into, and the sidewalls of the toothed grooves 31 are used to abut against the damping portion 21.

[0030] In some embodiments, the connecting member 23 is a gear, and the damping part 21 is a tooth on the gear, thus making the connecting member 23 easier to obtain. Correspondingly, a rack that meshes with the gear is provided on the housing 10. The meshing of the gear and the rack produces a damping effect.

[0031] In the connection structure of this embodiment, see Figure 3 The connecting component 2 includes: a fixing component 24, which is connected to the air guide plate 1; a connecting shaft 25, which is connected to the fixing component 24; the connecting shaft 25 passes through the connecting rod 22; the connecting component 23 is rotatably connected to the connecting shaft 25; and the connecting component 23 is located on the side of the connecting rod 22 away from the fixing component 24.

[0032] In some embodiments, the connecting component 23 is rotatably connected to the connecting rod 22 via the connecting shaft 25, and the connecting shaft 25 is connected to the air guide plate 1 via the fixing component 24, thereby increasing the strength of the structure.

[0033] In some embodiments, a guide rail is provided on the housing 10, the extension trajectory of the guide rail is an arc-shaped structure, the inner wall of the guide rail is used to abut against the damping part 21, the connecting part 23 is movably connected to the guide rail, and the connecting part 23 is movably provided along the extension direction of the guide rail.

[0034] See Figure 6 , Figure 7 In the connection structure of this embodiment, a first connecting part 11 is provided at one end of the air guide plate 1, and a second connecting part 12 is provided at the other end of the air guide plate 1. Both the first connecting part 11 and the second connecting part 12 are located on the rotation axis of the air guide plate 1. The connection structure also includes a drive motor 4, the output shaft of which is connected to the first connecting part 11, and the connecting rod 22 is connected to the second connecting part 12. With the above arrangement, the drive motor 4 is respectively located on opposite sides of the air guide plate 1, so that the two sides of the air guide plate 1 are subjected to force, thereby making the air guide plate 1 more stable during operation.

[0035] See Figure 6 In the connection structure of this embodiment, the first connecting part 11 is provided with a first connecting hole 111, and the second connecting part 12 is provided with a second connecting hole 121. The extension direction of the first connecting hole 111 and the extension direction of the second connecting hole 121 are both coincident with the rotation direction of the air guide plate 1. The output shaft of the drive motor 4 is inserted into the first connecting hole 111, and the connecting rod 22 is provided with a mounting shaft 26, which is inserted into the second connecting hole 121.

[0036] In the connection structure of this embodiment, there are multiple connecting components 2, which are arranged at intervals along a direction parallel to the rotation axis of the air guide plate 1; and / or, the air guide plate 1 includes an air guide plate body 13 and a connecting plate body 14, the connecting plate body 14 is arranged around the air guide plate body 13, the connecting plate body 14 protrudes from the surface of the air guide plate body 13, and the connecting components 2 are connected to both the air guide plate body 13 and the connecting plate body 14.

[0037] In some embodiments, there are multiple connecting components 2, which are arranged at intervals along a direction parallel to the rotation axis of the air guide plate 1, thereby enhancing the auxiliary effect of the connecting structure.

[0038] In some embodiments, the air guide plate 1 includes an air guide plate body 13 and a connecting plate body 14. The connecting plate body 14 is disposed around the air guide plate body 13 and protrudes from the surface of the air guide plate body 13. The connecting assembly 2 is connected to both the air guide plate body 13 and the connecting plate body 14. This improves the strength of the connection structure.

[0039] The air conditioner of this embodiment includes the connection structure described above. The housing 10 of the air conditioner is provided with a blocking part, which is used to abut against the damping part 21.

[0040] In the air conditioner of this embodiment, the housing 10 of the air conditioner has an air guide cavity for accommodating the air guide plate 1. The air guide plate 1 is rotatably disposed in the air guide cavity. The housing 10 is provided with a first limiting member 6 and a second limiting member 7. The first limiting member 6 and the second limiting member 7 are disposed at intervals. The first limiting member 6 and the second limiting member 7 are used to abut against the connecting component 2 to limit the position of the connecting component 2.

[0041] The air conditioner with a connecting structure in this embodiment consists of components such as fan blades, housing 10, connecting parts 23, air guide plate 1, and connecting rod 22. The air guide plate 1 is located below the air conditioner housing 10 and rotates towards the air duct. Because the air guide plate 1 experiences different wind forces at different positions, it rotates under the drive of the drive motor 4. During up-and-down sweeping and stationary operation, the air guide plate 1 experiences uneven forces due to changes in factors such as airflow stimulation, wind field, and gravitational force within the air conditioner, leading to vibration and noise issues. After long-term operation, the drive motor 4 needs to constantly overcome wind resistance. Since there is no other supporting force during operation, the play in the drive motor 4 increases, causing changes in the operating angle and severely reducing the comfort of the air conditioner. In severe cases, the air guide plate 1, rotating in the middle of the air duct, may vibrate violently due to the stimulation of the airflow from above and below. The air guide plate 1 may slap against the upper edge of the air outlet of the housing 10, potentially causing it to detach and affecting the reliability of its operation. Compared to ordinary air guide plates, the air guide plate 1 in this embodiment has an auxiliary connecting component 2 added to the side without the drive motor 4. The connecting component 2 serves as a limit and support; that is, the single drive motor 4 on the right side drives the air guide plate 1 to move up and down and to sweep the airflow. The connecting rod 22 drives the connecting component 23 to run along the track of the rack portion 3 of the housing 10, while simultaneously cooperating with the first limiting component 6 and the second limiting component 7 to limit movement and prevent vibration and other abnormalities. The connecting rod 22, the air guide plate 1, the housing 10, and the connecting component 23 together constitute the connecting assembly 2. The air guide plate 1 runs in the air duct under the drive of the right-side drive motor 4, and the left-side rotating shaft runs synchronously and at the same angle (rotating coaxially with the right-side drive motor 4). The left-side rotating shaft and the connecting rod 22 are an integral structure. The connecting rod 22 drives the connecting component 23 to mesh within the track of the rack part 3 of the housing 10. At the same time, the connecting rod 22 and the fixing block of the air guide plate 1 cooperate to limit and support the air guide plate 1. The tooth width, tooth height, tooth thickness, and module of the track of the connecting component 23 and the rack part 3 of the housing 10 must be consistent to ensure the reliability of meshing. Under the premise of meeting the actual use requirements, the tooth height should be as small as possible and the number of teeth should be as small as possible to reduce meshing resistance and improve running smoothness. The connecting rod 22 and the connecting shaft 25 cooperate with a 0.05mm gap on each side. A gear meshing structure is added to one or both sides of the air guide plate 1 that is not driven by the drive motor 4. This provides a buffering effect to prevent the air guide plate 1 from being subjected to large impact wind forces during operation, thus preventing it from shaking or falling off due to wind. At the same time, the air guide plate 1 runs smoothly under the action of the gear meshing structure, and the torque on the shaft of the air guide plate 1 driven motor 4 is smaller, extending the service life of both the air guide plate 1 and the drive motor 4.

[0042] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0043] The connection structure of the present invention includes: an air guide plate 1, rotatably connected to the housing 10 of the air conditioner; and a connection assembly 2, which includes a connecting rod 22, one end of which is connected to the air guide plate 1, and the other end of which is provided with a connecting component 23. The connecting component 23 is rotatably connected to the connecting rod 22, and the connecting component 23 has a damping part 21. When the air guide plate 1 stops rotating, the damping part 21 abuts against the housing 10 to limit the position of the air guide plate 1. With the above arrangement, when the air guide plate 1 is working, in order to prevent the air guide plate from being subjected to large impact wind forces, the damping part 21 plays a buffering role, preventing the air guide plate from shaking or falling off due to the wind. At the same time, due to the effect of the damping part 21, the torque on the air guide plate 1 is reduced, thereby making the air guide plate 1 run more smoothly and solving the problem of structural instability of the air guide plate in the prior art when guiding air.
