Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a latch structure of a moving plate and an air conditioner. Background Art

[0002] Indoor air conditioners are commonly equipped with left-right and top-down air guides to meet user needs for adjustable airflow direction. To achieve these functions, upper and lower air guides and left and right air guides are typically installed inside the air conditioner. These guides are secured with a specific latch to ensure radial rotation. This design allows users to freely adjust the airflow direction, thereby improving user comfort.

[0003] However, in practice, air deflectors are typically designed to be long and narrow, with 3-5 mounting holes evenly spaced throughout. In large-scale production environments, the limitations of plastic processing techniques make it difficult to maintain perfect coaxiality between adjacent mounting holes. This misalignment can cause unnecessary friction between the air deflector and the latches when moving, resulting in an unpleasant "clicking" sound that affects the user experience.

[0004] To address this issue, manufacturers typically add high-viscosity damping oil between the moving parts of the air deflector. This approach can alleviate the friction caused by insufficient coaxiality, thereby reducing noise. However, this solution also has significant drawbacks: on the one hand, the use of high-viscosity damping oil increases product cost; on the other hand, the damping oil will gradually lose or evaporate over time, causing the original problem to recur.

[0024] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In the embodiment of the present utility model, Figure 3-Figure 5 As shown, the structure of the latch 1 of the moving board 5 includes: a latch body 2, the latch body 2 having at least two side surfaces 3, the two side surfaces 3 are set at an angle, and the connection between the two is configured as an angular portion 4 for contacting the inner hole.

[0026] Specifically, in the prior art, Figure 1 、 Figure 2 As shown, the cross-section of the pin 1 is circular, and it is in full contact with the inner wall of the hole. An eccentric setting, on the one hand, produces unusual noise due to friction, and on the other hand, it is difficult to quickly install the pin 1. Specifically, the contact area between the cylindrical pin 1 and the hole wall becomes uneven, resulting in increased local contact pressure and thus increased friction. In an eccentric setting, the friction between the cylindrical pin 1 and the hole wall is unevenly distributed, resulting in increased local wear.

[0027] In an embodiment of the present utility model, at least two side surfaces 3 are provided at the latch body 2, and the two side surfaces 3 are arranged adjacent to each other, and the connection between them can be constructed into an angular portion 4, so that the angular portion 4 protrudes from the entire latch body 2, and only the angular portion 4 is in contact with the inner hole of the moving plate 5, while the side surface 3 is not in contact, thereby reducing the overall contact area between the latch body 2 and the inner hole, reducing friction, and avoiding abnormal noise. Of course, the angular portion 4 can also make the load more evenly distributed at the contact point, reduce local stress concentration, and improve the stability and reliability of the structure; and improve the overall running smoothness by reducing vibration and noise during movement. In addition, it can also adapt to different working conditions, including eccentric settings, inner holes of different materials, etc., and has high versatility and adaptability. As Figure 5 As shown, in this embodiment, six side surfaces 3 are provided, so that the cross-sectional area of ​​the latch body 2 is a regular hexagon.

[0028] This embodiment reduces the friction between the latch body 2 and the inner hole by reducing the contact area between the two, thereby improving the convenience of installation and alignment, enhancing stability and durability, and being adaptable to various working conditions.

[0029] In one embodiment, if Figure 3As shown, the latch body 2 has an axial direction, and the corner portion 4 extends along the axial direction of the latch body 2. Specifically, because the latch body 2 is inserted axially into the inner hole, the corner portion 4 in this embodiment also extends along the axial direction of the latch body 2, further reducing the contact area between the latch body 2 and the inner hole, thereby reducing friction during movement and preventing abnormal noise.

[0030] In one embodiment, if Figure 3 As shown, the side surface 3 smoothly transitions into the corner portion 4, reducing stress concentration points. When the latch body 2 is subjected to stress, the stress is more evenly distributed across the entire latch 1, preventing fatigue damage or fracture caused by localized excessive stress. This improves the overall strength and durability of the latch body 2, extending its service life. Furthermore, the smooth surface reduces friction and facilitates guidance during installation of the latch body 2. Furthermore, the corner portion 4 is chamfered, significantly reducing stress concentration, reducing friction and wear, improving installation and alignment convenience, and enhancing stability and durability.

[0031] In one embodiment, if Figure 3 、 Figure 4 The latch body 2 shown has a first end, which is provided with an end cap 6 that protrudes outside the inner hole. Specifically, to prevent the latch body 2 from dislodging from the inner hole, this embodiment secures an end cap 6 to the first end of the latch body 2. The diameter of the end cap 6 is larger than the diameter of the through hole, thereby blocking the end cap 6 from entering the through hole. This also facilitates quick identification of whether the latch body 2 is properly installed based on the installation position of the end cap 6.

[0032] In one embodiment, if Figure 3 As shown, the latch body 2 has a second end, which is disposed opposite the first end and is provided with a tensioning channel 8. This tensioning channel 8 ensures a tight connection between the latch body 2 and the inner hole after installation, reducing looseness and vibration and improving connection reliability. Preferably, the second end of the latch body 2 is provided with at least two tensioning arms 7, spaced apart to form the tensioning channel 8 therebetween.

[0033] The included angle between the two side surfaces 3 is defined as α, and α satisfies 0°<α<180°.

[0034] This embodiment also provides an air conditioner, including a moving plate 5 (in this embodiment, the moving plate 5 is an air guide plate) and the above-mentioned latch 1 structure. The specific structure of the latch 1 structure refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
