Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioners, and in particular to an air guide crank mounting structure and an air conditioner. Background Technology
[0002] In order to achieve better airflow and to improve the aesthetics of air conditioners, more and more air conditioners are equipped with large air deflectors.
[0003] Unlike regular small air deflectors, large air deflectors generally require a longer crank to allow for a larger range of rotation and thus better airflow. However, improper connection between the crank and the air deflector can cause vibration, leading to abnormal noises during air conditioner operation and affecting user experience. Overly complex connection structures also increase costs. Furthermore, since users can directly see the crank when the air conditioner is turned on, an overly complex connection structure can negatively impact the air conditioner's aesthetics.

Therefore, they should not be construed as limitations on this utility model.
[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.
[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0039] For ease of description, in this utility model, the direction in which the pin is inserted into the air guide and crank is considered the front, and the opposite direction is considered the rear.
[0040] like Figures 1 to 8 As shown, this utility model discloses a wind deflector crank mounting structure, comprising:
[0041] The air conditioner body 1 has an air outlet 11 at the bottom;
[0042] The air guide 2 has two mounting platforms 21 protruding on the side near the air outlet 11, and the mounting platforms 21 have a first mounting hole 22.
[0043] Two cranks 3 are used to connect the air conditioner body 1 and the air guide 2. They have a first end 31 and a second end 32. The first end 31 is rotatably connected to the air outlet 11 of the air conditioner body 1. The second end 32 has a downward-facing groove 321. The rear side wall of the groove 321 has a second mounting hole 322. The front side wall of the groove 321 has a third mounting hole 323. The two cranks 3 are respectively fitted onto the two mounting platforms 21 of the air guide 2 through the groove 321. The first mounting hole 22, the second mounting hole 322 and the third mounting hole 323 are aligned.
[0044] The pin 4 has a mushroom head 41 protruding from its front and a limiting part 42 at its rear. The pin 4 is limited and passes through the first mounting hole 22, the second mounting hole 322 and the third mounting hole 323 to fix the crank 3 and the air guide 2.
[0045] In this way, the crank 3 is respectively fitted onto the two mounting platforms 21 of the air guide 2 through the groove 321, and the crank 3 and the air guide 2 are fixed by the pin 4, forming a limiting assembly relationship with the mounting platforms 21 of the crank 3 and the air guide 2, so that the crank 3 is tightly assembled with the mounting platform 21, and the crank 3 is firmly installed and not easy to loosen.
[0046] like Figure 6 As shown, several limiting ribs 324 protrude towards each other on the rear and front sidewalls of the groove 321. The limiting ribs 324 cooperate with the mounting platform 21 to form a limiting relationship, preventing the mounting platform 21 from shaking within the groove 321. To make the mounting platform 21 and the limiting ribs 324 fit more tightly, multiple limiting ribs 324 are symmetrically arranged on the rear and front sidewalls of the groove 321.
[0047] like Figure 8 As shown, the gap between the limiting rib 324 and the mounting platform 21 is 0.1mm to 0.3mm, which further prevents the crank 3 from moving back and forth.
[0048] like Figure 6 As shown, the first mounting hole 22 on the mounting platform 21 includes, from back to front, a first hole segment 221, a second hole segment 222, and a third hole segment 223, with the diameters of the first hole segment 221, the second hole segment 222, and the third hole segment 223 decreasing sequentially. The inner wall of the first hole segment 221 is a first guide surface 224, and the second hole segment 222 and the third hole segment 223 are connected by a second guide surface 225. The first guide surface 224 and the second guide surface 225 improve the smoothness of the installation of the pin 4 and increase assembly efficiency.
[0049] like Figure 8As shown, the diameter D2 of the third hole 223 is greater than the diameter D1 of the rear end of the mushroom head 41, and the diameter D1 of the rear end of the mushroom head 41 is greater than the diameter of the third mounting hole 323. In this way, after the pin 4 is assembled with the crank 3 and the mounting platform 21, the axial movement of the pin 4 can be limited, which can prevent the pin 4 from coming out backward and prevent the pin 4 from moving forward.
[0050] like Figure 6 and Figure 7 As shown, a first stop surface 3221 is provided on the side of the second mounting hole 322 near the mounting platform 21, and a third guide surface 3222 is provided on the side of the second mounting hole 322 away from the mounting platform 21. The front end of the upper limit portion 42 of the pin 4 is provided with a second stop surface 421 that mates with the first stop surface 3221. In this way, after the pin 4 is assembled with the crank 3 and the mounting platform 21, the pin 4 is stopped when inserted.
[0051] When the latch 4 is positioned within the first mounting hole 22, the second mounting hole 322, and the third mounting hole 323, the rear part of the latch 4 is located within the second mounting hole 322, and the front part of the latch 4 is located within the third mounting hole 323. In this way, both the front and rear parts of the latch 4 are hidden inside the crank 3. When using the air conditioner, there are no exposed assembly structures when viewed from the front, which does not affect the overall appearance of the air conditioner and provides a good user experience.
[0052] like Figure 8 As shown, in this utility model, the diameter D3 of the second hole section 222 is not less than the diameter D1 of the rear end of the mushroom head 41 on the pin 4, thereby reducing the resistance during the insertion of the pin 4 and improving the smoothness of assembly; the diameter D2 of the third hole section 223 is greater than the shaft diameter D4 of the pin 4 and the difference between D2 and D4 is 0.1mm to 0.5mm, thereby ensuring that the radial direction of the pin 4 is reliably limited.
[0053] like Figure 3 , Figure 7 and Figure 8 As shown, the front of the pin 4 has an axially arranged elastic groove 43, which makes the mushroom head 41 elastic, allowing it to undergo a certain elastic deformation during insertion, facilitating installation. To prevent the bottom of the elastic groove 43 from deforming or breaking due to stress concentration when the mushroom head 41 undergoes elastic deformation, the bottom of the elastic groove 43 is arc-shaped. To prevent damage to the pin 4 and to allow the mushroom head 41 to pass smoothly through the third hole section 223 of the mounting platform 21 through elastic deformation, the width a of the elastic groove 43 is not less than the difference between the diameter D1 of the rear end of the mushroom head 41 and the diameter D2 of the third hole section 223.
[0054] This utility model also discloses an air conditioner, including a guide valve crank mounting structure as described above.
[0055] All features described in the specification, appended claims and drawings, whether individually or in any combination thereof, are essential features of this utility model.
