[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

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

[0036] Combine the following Figure 1-Figure 8 The invention describes a connection structure for an air guide plate of an air conditioner provided in an embodiment of the invention.

[0037] like Figure 1 As shown, an embodiment of the utility model provides a connection structure for an air guide plate of an air conditioner, which is used to connect the air guide plate 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 guide plate 100, and the connection structure includes a pin shaft body 1, elastic fixing teeth 2 and claws 3.

[0038] The pin body 1 is the core component of the connection structure, and the pin body 1 carries the main function of connecting the air guide plate 100 and the air duct 200. The outer periphery of one end of the pin body 1 is provided with elastic fixing teeth 2 for matching with the tooth grooves 101 on the air guide plate 100. The elastic fixing teeth 2 are designed to be elastic, which means that they can adapt to a certain degree of deformation to better match the tooth grooves 101 while providing a certain tightening force. The elastic fixing teeth 2 are selectively fixed to one of the tooth grooves 101 to ensure circumferential fixation; the elastic fixing teeth 2 ensure the stability and reliability of the connection.

[0039] The other end of the pin body 1 is provided with a claw 3, which is fixedly connected to the air duct 200. This arrangement allows the connection structure to be firmly installed on the air duct 200, providing a stable support point for the air guide plate 100. The specific form of the claw 3 may include but is not limited to a hook, a buckle, etc., to ensure close fit with the air duct 200 and quick installation.

[0040] The connection structure for the air-conditioning air deflector provided by the present utility model can adjust the angle of the air deflector 100 by rotating the pin shaft body 1. The elastic fixing teeth 2 will engage with different tooth grooves 101 while the pin shaft body 1 itself remains stationary, enabling multi-angle air outlet of the air deflector 100. Moreover, the air deflector 100 can accurately adjust the angle manually. The connection structure centralizes key structures and can be called a universal accessory, saving the mold space of the air deflector 100 and the air duct 200.

[0041] In a feasible embodiment of the present utility model, two elastic fixing teeth 2 are arranged on the outer periphery of the pin shaft body 1, 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 connection structure.

[0042] More specifically, the symmetrically arranged elastic fixing teeth 2 achieve balance in mechanics, reducing the deflection or stress concentration phenomena that may occur due to asymmetric design. This helps to extend the service life of the connection structure and reduce the risk of wear or damage caused by long-term use. The two elastic fixing teeth 2 cooperate with the tooth grooves 101 on the air deflector 100 simultaneously, providing stronger fastening force. This dual-locking mechanism ensures that the air deflector 100 will not loosen or fall off easily 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 their directions 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 installation difficulty and complexity and improves the installation efficiency.

[0043] As Figure 2 shown, the diameter of the pin shaft body 1 is set to D, where 5mm < D < 12mm. Moreover, the pin shaft body 1 can be set as a hollow shaft.

[0044] As Figure 3 shown, in a feasible embodiment of the present utility model, the tooth thickness of the elastic fixing teeth 2 is h, where 2mm < h < 8mm. This design range is considered 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 usually be provided because it can increase the contact area with the tooth grooves 101, thereby enhancing the frictional force and anti-slip ability of the connection. However, too thick teeth may also cause installation difficulties or unnecessary material waste. Appropriate tooth thickness helps to ensure that the elastic fixing teeth 2 maintain their shape and performance during long-term use, resisting fatigue and wear. Elastic fixing teeth 2 that are too thin or too thick may both lead to a decline in durability. In addition, the selection of tooth thickness also needs to consider the compatibility with the tooth grooves 101. Different sizes and shapes of tooth grooves may require teeth of different thicknesses to ensure the best fitting effect.

[0045] As Figure 4As shown, in a feasible embodiment of the present utility model, the tooth height of the elastic fixing tooth 2 is t, where 0.4 mm < t < 1.5 mm. This design range is based on the consideration of multiple key factors, including the connection strength, the flexibility of the elastic fixing tooth 2, and the compatibility of the mating components. The increase in the tooth height t generally means an increase in the contact area with the tooth groove 101, which helps to enhance the connection strength and stability. However, an excessively high tooth height may increase the manufacturing difficulty and cost, and may affect the installation convenience. Within the given range, a lower tooth height (close to 0.4 mm but greater) may make the elastic fixing tooth 2 have better flexibility and be able to more easily adapt to the 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. Different depths and shapes of the tooth groove 101 may require teeth of different heights to ensure the best fitting effect. The change in the tooth height also affects the stress distribution in the connection structure. An appropriate tooth height helps to optimize the stress distribution, reduce the stress concentration phenomenon, and thus improve the durability and reliability of the connection.

[0046] In a feasible embodiment of the present utility model, the claws 3 are arranged in pairs to achieve the connection with the pin shaft body 1 and the clamping and fixing of the air duct 200. And the elastic deformation directions of the two claws 3 are 180 degrees.

[0047] As Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, each claw 3 includes a deformable arm 31 and a claw body 32. The deformable arm 31 is connected to the pin shaft body 1. The claw 3 is allowed to deform when receiving an external force, so as to adapt to different installation conditions or adjust its position to better cooperate with the air duct 200 or other components. In order to realize the function of the deformable arm 31, it is necessary to select materials with certain elasticity and toughness, such as stainless steel, spring steel or some polymer materials. These materials can deform when receiving an external force and return to the original shape after the external force disappears.

[0048] The claw body 32 is arranged at one end of the deformable arm 31 facing 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 the air duct 200 and generates a clamping effect. It usually has a specific shape and size to closely cooperate 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 torques during the working process; at the same time, its surface may need to be specially treated (such as coated with anti-slip materials) to increase the friction force with the air duct 200, so as to ensure the stability and reliability of the connection.

[0049] In a feasible embodiment of the present utility model, the length of the deformable arm 31 is a, where 2 mm < a < 8 mm. The length of the deformable arm 31 directly affects its deformation ability. A longer arm (close to 8 mm but not exceeding) generally has better flexibility and deformation range, and can more easily adapt to minor deviations during the installation process or the complex shape of the air duct 200. However, an overly long arm may reduce the overall rigidity and stability. The length a also determines the space required by the claw 3 during the installation process. In compact or space-constrained application scenarios, shorter arms (close to 2 mm but greater) may be more suitable as they occupy less space. The length of the deformable arm 31 also affects the stress distribution in the connection structure. An appropriate length helps optimize the stress distribution, reduce stress concentration, and thus improve the durability and reliability of the connection. The selection of the length a also affects the manufacturing cost. Shorter deformable arms 31 may be easier to manufacture and have lower costs, but overly short arms may not meet all functional requirements.

[0050] In a feasible embodiment of the present utility model, the thickness of the deformable arm 31 is c, where 0.8 mm < c < 2.5 mm. A thicker deformable arm (close to 2.5 mm but not exceeding) generally has higher structural strength, can withstand greater forces and torques, and reduce deformation or damage caused by external forces. However, overly thick arms may increase the overall weight and cost, and may affect their deformation ability. The thickness c also directly affects the flexibility and deformation ability of the deformable arm. Thinner arms (close to 0.8 mm but greater) are generally more likely to deform, and can better adapt to minor deviations during the installation process or the complex shape of the air duct 200. However, overly thin arms may reduce their fatigue resistance and durability.

[0051] As Figure 7 shown, in a feasible embodiment of the present utility model, it further includes positioning rib pins 4, which are arranged on the pin shaft body 1 and located on both sides of the claw 3. The positioning rib pins 4 are adapted to the air duct 200 to limit the circumferential rotation of the air duct 200. Generally speaking, the depth of the positioning rib pins 4 is e, and e is greater than 1 mm. The positioning rib pins 4 are adapted to the corresponding structures (such as holes, grooves, etc.) on the air duct 200, and limit the circumferential rotation of the air duct through physical contact. This limitation is crucial for preventing the air duct from accidentally rotating due to external forces during operation, ensuring the stable operation of the system. Although the main function of the positioning rib pins 4 is to limit circumferential rotation, they may also provide axial support to a certain extent, helping to maintain the correct distance and positional relationship between the air duct and the pin shaft body.

[0052] The connection structure for the air-conditioning air deflector provided in the first aspect of the present utility model concentrates the structure that requires multi-directional mold ejection of the mold on the pin shaft body 1 of the connection structure, facilitating the mold opening of the air deflector 100 and the air duct 200. Moreover, when the manual air deflector 100 changes direction, it has a clear sense of gear.

[0053] The second aspect of the utility model is to provide an air-conditioning air guide plate assembly, including an air guide plate 100, an air duct 200 and a connection structure for an air-conditioning air guide plate as described above, one end of which is connected to the air guide plate 100 and the other end of which is connected to the air duct 200.

[0054] A third aspect of the present invention provides an air conditioner, comprising a connection structure for an air guide plate of an air conditioner as described in any one of the above items, or an air guide plate assembly of an air conditioner as described above.

[0055] The air conditioner provided by the utility model has the various advantages as described above because it includes the connection structure for the air guide plate of the air conditioner as described above.
