[0035] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described below in conjunction with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments.

In addition, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0037] The connecting structure for an air conditioner air deflector provided by the embodiments of the present application will be described below in conjunction with FIGS. 1-8.

[0038] As shown in FIG. 1, the present application provides a connecting structure for an air conditioner air deflector, which is used to connect the air deflector 100 and the air duct 200. A plurality of tooth grooves 101 are arranged on the inner periphery of the shaft hole at one end of the air deflector 100. The connecting structure includes a pin shaft body 1, elastic fixing teeth 2 and a pawl 3.

[0039] The pin shaft body 1 is the core component of the connecting structure, and the pin shaft body 1 bears the main function of connecting the air deflector 100 and the air duct 200. The outer periphery of one end of the pin shaft body 1 is provided with elastic fixing teeth 2, which are used to cooperate with the tooth grooves 101 on the air deflector 100. The elastic fixing teeth 2 are designed to be elastic, meaning that they can adapt to a certain degree of deformation to better match the tooth grooves 101, while providing a certain fastening force. The elastic fixing teeth 2 are selectively fixed with one of the tooth grooves 101 to ensure circumferential fixation; the elastic fixing teeth 2 ensure the stability and reliability of the connection.

[0040] The other end of the pin shaft body 1 is provided with a pawl 3, which is fixedly connected with the air duct 200. This arrangement allows the connecting structure to be firmly mounted on the air duct 200, providing a stable support point for the air deflector 100. Specifically, the pawl 3 can include but is not limited to a hook, a buckle, etc., to ensure close cooperation and quick installation with the air duct 200.

[0041] The connecting structure for the air deflector provided by the present application can adjust the angle of the air deflector 100 by rotating the pin shaft body 1, which is fixed in place, and engaging the elastic fixing teeth 2 with different tooth grooves 101. This can achieve multi-angle air outlet of the air deflector 100, and the air deflector 100 can manually and accurately adjust the angle of air outlet. The connecting structure concentrates the key structures, which can be called a universal accessory, saving the mold space of the air deflector 100 and the air duct 200.

[0042] In one possible embodiment of the present application, the pin shaft body 1 is provided with two elastic fixing teeth 2, and the two elastic fixing teeth 2 are symmetrically arranged with respect to the axis of the pin shaft body 1. This design further enhances the stability and reliability of the connecting structure.

[0043] More specifically, the symmetrically arranged elastic fixing teeth 2 achieve mechanical balance, reducing the deflection or stress concentration phenomenon that may occur due to asymmetric design. This helps to prolong the service life of the connecting structure and reduce the risk of wear and tear or damage due to long-term use. The two elastic fixing teeth 2 simultaneously cooperate with the tooth grooves 101 on the air deflector 100, providing stronger fastening force. This double locking mechanism ensures that the air deflector 100 will not easily loosen or fall off when subjected to wind force, vibration or other external forces. Due to the symmetric arrangement of the elastic fixing teeth 2, users do not need to pay special attention to the direction during installation, and only need to simply insert the pin shaft body 1 into the shaft hole of the air deflector. This greatly reduces the difficulty and complexity of installation, improving installation efficiency.

[0044] As shown in FIG. 2, the diameter of the pin shaft body 1 is set as D, and 5mm < D < 12mm. Moreover, the pin shaft body 1 can be a hollow shaft.

[0045] As shown in FIG. 3, in one possible embodiment of the present application, the tooth thickness of the elastic fixing teeth 2 is h, and 2mm < h < 8mm. This design range is based on multiple factors, including the stability of the connection, the durability of the elastic fixing teeth, and the compatibility with other components. By setting the above size range, better stability can generally be provided, as it can increase the contact area with the tooth grooves 101, thereby enhancing the friction and anti-slip ability of the connection. However, excessively thick teeth can also cause installation difficulties or unnecessary material waste. Proper tooth thickness helps to ensure that the elastic fixing teeth 2 maintain their shape and performance during long-term use, resisting fatigue and wear. Both too thin or too thick elastic fixing teeth 2 can lead to reduced durability. In addition, the selection of tooth thickness also needs to consider the compatibility with the tooth grooves 101, as different sizes and shapes of tooth grooves may require different thickness of teeth to ensure the best fitting effect.

[0046] As shown in FIG. 4, in one possible embodiment of the present application, the elastic fixing tooth 2 has a tooth height t, 0.4mm < t < 1.5mm. This design range is based on the consideration of multiple key factors, including the strength of the connection, the flexibility of the elastic fixing tooth 2, and the compatibility with the mating components. An increase in the tooth height t generally means an increase in the contact area with the tooth groove 101, which helps to enhance the strength and stability of the connection. However, too high a tooth height can increase the difficulty and cost of manufacturing, and may affect the convenience of installation. Within the given range, a lower tooth height (close to 0.4mm but greater than) can make the elastic fixing tooth 2 have better flexibility, which can more easily adapt to minor changes or deviations of the tooth groove 101. The selection of the tooth height also needs to consider the compatibility with the tooth groove 101. Tooth grooves 101 of different depths and shapes may require teeth of different heights to ensure optimal mating results. Changes in tooth height will also affect the distribution of stress in the connection structure. A proper tooth height helps to optimize the stress distribution, reduce stress concentration, and thus improve the durability and reliability of the connection.

[0047] In one possible embodiment of the present application, the claws 3 are arranged in pairs to achieve the connection with the pin shaft body 1 and the clamping fixation of the air duct 200. The elastic deformation directions of the two claws 3 are 180 degrees.

[0048] As shown in FIGS. 5, 6, 7 and 8, each claw 3 includes a deformable arm 31 and a claw body 32. The deformable arm 31 is connected with the pin shaft body 1, and the claw 3 allows deformation when receiving external force, thereby adapting to different installation conditions or adjusting its position to better mate with the air duct 200 or other components. In order to achieve the function of the deformable arm 31, a material with certain elasticity and toughness needs to be selected, such as stainless steel, spring steel or certain polymer materials. These materials can deform when subjected to external force and return to their original shape after the external force disappears.

[0049] The claw body 32 is arranged at the end of the deformable arm 31 away from the pin shaft body 1, and the claw body 32 is clamped and fixed with the air duct 200. The claw body 32 is the part of the claw 3 that directly contacts and produces a clamping effect with the air duct 200. It usually has a specific shape and size in order to tightly mate with the corresponding structure on the air duct 200. The design of the claw body 32 needs to fully consider the structural characteristics and usage requirements of the air duct 200. For example, it may need to have sufficient rigidity and strength to withstand various forces and moments during operation; at the same time, its surface may need to be specially treated (such as coated with anti-slip material) to increase the friction between it and the air duct 200, thereby ensuring the stability and reliability of the connection.

[0050] In one feasible embodiment of the present application, the length of the deformable arm 31 is a, 2mm < a < 8mm. The length of the deformable arm 31 directly affects its deformation ability. Longer arms (close to 8mm but not exceeding) generally have better flexibility and deformation range, and can more easily adapt to minor deviations in the installation process or the complex shape of the air duct 200. However, too long an arm can reduce the overall rigidity and stability. The length a also determines the space required for the clamping jaw 3 during installation. In compact or space-limited application scenarios, shorter arms (close to 2mm but greater than) can be more suitable as they occupy less space. The length of the deformable arm 31 also affects the distribution of stress in the connecting structure. An appropriate length helps to optimize stress distribution, reduce stress concentration, and thus improve the durability and reliability of the connection. The choice of length a also affects the manufacturing cost, and shorter deformable arms 31 can be easier to manufacture and less expensive, but too short an arm can not meet all functional requirements.

[0051] In one feasible embodiment of the present application, the thickness of the deformable arm 31 is c, 0.8mm < c < 2.5mm. Thicker deformable arms (close to 2.5mm but not exceeding) generally have higher structural strength, can withstand greater forces and moments, and reduce deformation or damage caused by external forces. However, too thick an arm can increase the overall weight and cost, and can affect its deformation ability. The thickness c also directly affects the flexibility and deformation ability of the deformable arm. Thinner arms (close to 0.8mm but greater than) are generally more prone to deformation and can better adapt to minor deviations in the installation process or the complex shape of the air duct 200. However, too thin an arm can reduce its fatigue resistance and durability.

[0052] As shown in FIG. 7, in one feasible embodiment of the present application, the positioning rib pin 4 is provided on the pin shaft body 1 and located on both sides of the clamping jaw 3. The positioning rib pin 4 is adapted to the air duct 200 to limit the circumferential rotation of the air duct 200. Generally, the depth of the positioning rib pin 4 is e, e is greater than 1mm. The positioning rib pin 4 is adapted to the corresponding structure (such as a hole, a slot, etc.) on the air duct 200, and limits the circumferential rotation of the air duct through physical contact. This limitation is crucial to prevent the air duct from accidentally rotating due to external forces during operation, ensuring stable operation of the system. Although the main function of the positioning rib pin 4 is to limit the circumferential rotation, they can also provide some axial support to help maintain the correct distance and positional relationship between the air duct and the pin shaft body.

[0053] The connecting structure for the air deflector provided in the first aspect of the present application concentrates the structure that needs to be multi-directionally ejected from the mold on the connecting structure pin shaft body 1, facilitating the mold opening of the air deflector 100 and the air duct 200. Moreover, the manual air deflector 100 has a clear gear feel when changing direction.

[0054] The second aspect of the present application is to provide an air conditioner air deflector assembly, comprising an air deflector 100, an air duct 200, and the connecting structure for the air deflector of the air conditioner as described in any one of the above.

[0055] The third aspect of the present application is to provide an air conditioner, comprising the connecting structure for the air deflector of the air conditioner as described in any one of the above, or the air conditioner air deflector assembly as described in the above.

[0056] The air conditioner provided by the present application has various advantages as described above due to comprising the connecting structure for the air deflector of the air conditioner as described in the above.
