[0002] The use of air conditioners (air conditioners) has become more and more popular with the improvement of living standards, and consumers have higher and higher requirements for the appearance and functions of air conditioners. The existing air guide mechanism of the air conditioner is usually limited by the shafts at both ends, and then the driving motor drives the air guide plate to rotate through the crank, or the motor shaft is directly driven. Due to the clearance between the air guide plate and the driving parts, there is a virtual position of movement; at the same time, the existing air guide plate is supported by the rotating shafts at both ends, and there must be a certain gap in the middle limit method due to the assembly and movement of parts, and the smaller the gap is designed, the more unfavorable it is for production. Therefore, the theoretical gap will be appropriately enlarged due to the actual production limitations, resulting in the defects of the air guide plate moving left and right and shaking, affecting the quality of the air conditioner.

[0003] As attached Figure 3 The figure shows the motor-driven air deflector motion mechanism. The air deflector is usually provided with a rotating shaft at one end and a flat hole that matches the motor shaft at the other end. At the same time, a rotating hole or a sleeve that matches the shaft is provided at one end of the support panel or the air outlet frame. The drive motor is pre-installed on the air outlet frame at the other end, and then the air deflector is assembled into the drive motor shaft by deformation and extrusion, so as to realize the direct drive motor to rotate the air deflector. However, this air deflector motion mechanism has poor self-locking force and large left and right movement, which can easily cause the air deflector to shake under high wind speed.

It should be understood that the numbers used in this way can be interchanged under appropriate circumstances to facilitate the embodiments of the present invention described herein.

[0024] Embodiment 1, an anti-movement air guide plate.

[0025] As attached Figure 1 and attached Figure 2 As shown, an anti-movement air guide plate of the present embodiment includes an air guide plate 1, a sleeve side drive box 6a, an elastic component, a sleeve 2, a drive box cover 7 and a drive device, the sleeve 2 and the sleeve side drive box 6a are integrally formed, the air guide plate 1 includes a first rotating shaft 11 and a second rotating shaft 12, the first rotating shaft 11 passes through the sleeve side drive box 6a and is connected to the drive box cover 7 through the elastic component, the elastic component is arranged in the sleeve 2, the sleeve side drive box 6a and the drive box cover 7 are fixedly connected, and the second rotating shaft 12 is connected to the drive device.

[0026] The shaft sleeve 2 and the shaft sleeve side drive box 6a are integrally formed, which can reduce the number of parts and improve production efficiency; the air guide plate 1 is connected to the air outlet panel of the air conditioner through a first rotating shaft 11 located on the left and a second rotating shaft 12 located on the right, respectively, to realize the rotation of the air guide plate 1.

[0027] In this embodiment, the elastic component includes a spring 5 and a top plate 3, one end face of the spring 5 is connected to the drive box cover 7, the other end face of the spring 5 is connected to one end face of the top plate 3, and the other end face of the top plate 3 is connected to the air guide plate 1; the spring 5 is in a compressed state, and the compression degree of the spring 5 is adjustable; the top plate 3 is a rubber part.

[0028] The elastic component can be any component that can provide elastic force. In this embodiment, the spring 5 is used to provide elastic force, and the top plate 3 is used as an auxiliary connecting device for explanation. The wire diameter of the spring 5 can be adjusted according to different requirements to generate different preload forces.

[0029] The top plate 3 is specifically a T-shaped structure, with the end with a smaller cross-sectional area inserted into the spring 5, and the end face of the end with a larger cross-sectional area connected to the first rotating shaft 11 of the air guide plate 1; the top plate 3 is selected to have a rubber structure, and the damping generated by the rubber and the injection molded parts can be used to further weaken the shaking of the air guide plate 1; because the spring 5 is always in a compressed state, it always provides a rightward pressing force, pushing the top plate 3 to always push the air guide plate 1 to the right, thereby ensuring that the right side of the air guide plate 1 is always tightly matched with the corresponding groove of the driving gear 4, eliminating the assembly virtual position.

[0030] In this embodiment, the driving device includes a driving gear 4 and a driving side driving box 6b, and the second rotating shaft 12 of the air guide plate 1 passes through the driving side driving box 6b to connect to the driving gear 4; the second rotating shaft 12 is a swing arm structure, and two circular protrusions 121 are provided on the second rotating shaft 12; the circular protrusion 121 is used to connect the air guide plate 1 and the driving gear 4, and the circular protrusion 121 is specifically a frustum structure, and the cross-sectional area of ​​the circular protrusion 121 on the side connected to the air guide plate 1 is larger than the cross-sectional area of ​​the circular protrusion 121 on the side connected to the driving gear 4.

[0031] The second rotating shaft 12 of the air guide plate 1 cooperates with the driving gear 4 to realize a swing arm, which can provide a large self-locking force, thereby preventing the shaking problem caused by the air outlet acting on the air guide plate 1. The second rotating shaft 12 of the air guide plate 1 adopts a circular protrusion 121 of a truncated cone structure to cooperate with the corresponding groove of the driving gear 4. Under the push of the left top plate 3, it always fits the gear, eliminating the virtual position between the air guide plate 1 and the gear, optimizing the shaking, and eliminating the left and right movement. The circular protrusion 121 of the truncated cone structure can be better inserted into the corresponding groove of the gear.

[0032] The specific implementation process of this embodiment: in the anti-movement air guide plate 1 of this embodiment, the first rotating shaft 11 on the left side of the air guide plate 1 passes through the sleeve side drive box 6a and is assembled in the inner hole of the sleeve 2, and the second rotating shaft 12 on the right side of the air guide plate 1 passes through the drive side drive box 6b and is assembled in the corresponding groove of the drive gear 4; the sleeve 2 and the drive box cover 7 are integrally formed, and the drive gear 4 is assembled in the corresponding groove of the drive side drive box 6b through the shaft hole; wherein the first rotating shaft 11 on the left side of the air guide plate 1 can rotate freely in the sleeve 2; the two frustum protrusions of the second rotating shaft 12 on the right side of the air guide plate 1 are inserted into the corresponding groove of the drive gear 4, and there is no relative movement between the two, ensuring their synchronous movement to eliminate the motion virtual position; the spring 5 is installed in the sleeve 2 on the drive box cover 7, and the top plate 3 is inserted into the corresponding circle of the spring 5 in the sleeve 2 from the side, allowing the top plate 3 to rotate along the inner circle of the sleeve 2 and slide left and right. After being assembled in place, the spring 5 is always in a compressed state, thereby always providing a rightward pressing force, pushing the top plate 3 to always push the air guide plate 1 to the right, thereby ensuring that the right side cone and flat position of the air guide plate 1 are always tightly matched with the corresponding groove of the driving gear 4, eliminating the assembly virtual position; at the same time, under the squeezing action of the top plate 3, the air guide plate 1 cannot move left and right in a natural state or in a wind-blown state, thereby eliminating the defects of left and right movement and shaking of the air guide plate 1.

[0033] The air conditioner adopting the anti-movement air guide plate 1 of this embodiment eliminates the defect of the air guide plate 1 moving left and right. The air guide plate 1 rotating shaft and the driving part truncated cone are matched to achieve automatic adjustment to ensure the matching clearance of the rotating shaft, thereby optimizing or even eliminating the shaking defect and the left and right movement defect of the air guide plate 1, and improving the stability and reliability of the air guide mechanism. In addition, the automatic adjustment of the matching clearance between the air guide plate 1 and the driving part can allow the part production size fluctuation to a greater extent, facilitate long-term stable batch production, improve the product qualification rate, and thus reduce production costs.
