Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Fig. 1 shows an embodiment of the air deflection assembly of the present invention, which includes an air outlet frame 10, an air deflection plate 20 and a driving assembly 30, as shown in fig. 2 and 3. An air outlet 11 is formed in the air outlet frame 10, and the air deflector 20 is movably installed at the air outlet 11. The driving assembly 30 is installed on the air-out frame 10 and is in driving connection with the air deflector 20. The driving assembly 30 includes a motor 31, a step gear 32, a first rack 33 and a second rack 34, the step gear 32 is mounted on an output shaft of the motor 31, the step gear 32 includes a first driving gear 321 and a second driving gear 322 which are stacked, the first rack 33 is hinged to a first position of the air deflector 20 and is in driving connection with the first driving gear 321, and the second rack 34 is hinged to a second position of the air deflector 20 and is in driving connection with the second driving gear 322. The second position of the air deflector 20 is spaced apart from the first position of the air deflector 20, and the linear velocity obtained at the second position of the air deflector 20 is not equal to the linear velocity obtained at the first position of the air deflector 20.
By applying the technical scheme of the invention, when the air deflector assembly runs, the motor 31 drives the step gear 32 to rotate, the first driving gear 321 drives the first position of the air deflector 20 to extend through the first rack 33, and the second driving gear 322 drives the second position of the air deflector 20 to extend through the second rack 34. Because the linear velocity obtained by the second position of the air deflector 20 is not equal to the linear velocity obtained by the first position of the air deflector 20, the second position of the air deflector 20 is inclined relative to the first position of the air deflector 20, so that the air deflector 20 can be inclined relatively to realize air guiding in the process of extending from the air outlet 11.
Therefore, in the technical scheme of the invention, the problem of condensation of the air deflector 20 can be effectively solved through the extension structural design of the air deflector 20; meanwhile, the single motor 31 can control the air deflector 20 to extend and guide air, and the cost and the noise generated during the operation of the motor are reduced.
As shown in fig. 4 and 5, in the technical solution of the present embodiment, the first position of the air deflector 20 is close to the inner side of the outlet 11 relative to the air-out frame 10, and the second position of the air deflector 20 is close to the outer side of the outlet 11 relative to the air-out frame 10, so that the air can be discharged towards the outer side of the air-out frame 10.
Correspondingly, in the technical solution of this embodiment, the linear velocity obtained at the second position of the air deflector 20 is greater than the linear velocity obtained at the first position of the air deflector 20. As shown in fig. 2 and 6, in the present embodiment, the driving assembly 30 further includes a stepped speed-changing gear 35, the stepped speed-changing gear 35 includes a small pitch circle gear 351 and a large pitch circle gear 352 which are stacked, the small pitch circle gear 351 is connected to the second rack 34, and the large pitch circle gear 352 is connected to the second driving gear 322. When the wind deflector is used, the second driving gear 322 drives the large pitch circle gear 352 to rotate, and the small pitch circle gear 351 improves the rotating speed output, so that the linear velocity obtained at the second position of the wind deflector 20 is greater than the linear velocity obtained at the first position of the wind deflector 20, and the wind deflector 20 obliquely extends out.
As another alternative, the linear velocity obtained at the second position of the air deflector 20 may be greater than the linear velocity obtained at the first position of the air deflector 20 by a speed change gear set installed between the second drive gear 322 and the second rack 34. The actual speed regulating parameters of the speed changing gear set can be correspondingly adjusted according to actual use requirements.
As shown in fig. 2 and 4, in the present embodiment, the second rack 34 is an arc-shaped rack. The second rack 34 of the arc-shaped rack is more suitable for the structure requirement that the air deflector 20 extends obliquely, so that the air deflector 20 extends obliquely more naturally. As a further alternative, a straight articulated pivotable toothed rack can also be used.
More preferably, as shown in fig. 2, the driving assembly 30 further includes a rack movement guide 36, and the rack movement guide 36 is installed in the air-out frame 10 and is engaged with the first rack 33 and the second rack 34. The rack movement guide part 36 is installed at a position connected to the first and second racks 33 and 34, and the moving direction of the first and second racks 33 and 34 may be restricted by the rack movement guide part 36, so that the first and second racks 33 and 34 move more smoothly.
As shown in fig. 7, in the present embodiment, a first guide groove 331 that is engaged with the rack movement guide member 36 is formed in the first rack 33, and a second guide groove 341 that is engaged with the rack movement guide member 36 is formed in the second rack 34. Through the above-mentioned guide groove structure, the rack movement guide member 36 can be effectively matched with the first rack 33 and the second rack 34, and the movement stability of the first rack 33 and the second rack 34 can be improved. The optional first and second guide grooves 331 and 341 are raised guide grooves.
In order to facilitate the installation of the hinge coupling structure of the present invention, as shown in fig. 7 and 8, a first end of the first rack 33 is provided with a first hinge catch 332, and a first position of the air deflector 20 is provided with a first hinge groove 21 coupled to the first hinge catch 332. The first end of the second rack 34 is provided with a second hinge latch 342, and the second position of the air deflector 20 is provided with a second hinge slot 22 matched with the second hinge latch 342. When the air deflector is installed and used, the first hinge latch 332 and the second hinge latch 342 are respectively latched into the first hinge slot 21 and the second hinge slot 22, so that the air deflector 20 can be quickly installed.
More preferably, the second hinge slot 22 is a sliding slot structure, and the sliding slot structure is matched with the second hinge buckle 342, so that the radius of the second rack 34 is larger, the angle with the panel is smaller, the length and height of the second rack 34 are further effectively reduced, and the size of the whole mechanism is remarkably reduced to match the space of the panel.
As shown in fig. 5 and 7, in the technical solution of the present embodiment, a limiting hook 333 is disposed at the second end of the first rack 33, and the limiting hook 333 is matched with the air-out frame 10 to prevent the first rack 33 from being separated. It should be further noted that, with the above structure, the first rack 33 can bear the weight of the air deflector 20 with the aid of the air outlet frame 10, so that the gravity moment of the air deflector 20 acting on the shaft of the motor 31 can be effectively reduced, and the smaller wind sweeping motor 31 is used, so that the cost is reduced, and the noise is further reduced.
As a more preferable embodiment, as shown in fig. 4 and 6, the first driving gear 321 is formed with a gear section and a smooth section, the gear section is in driving connection with the first rack 33, and the first position of the driving wind deflector 20 extends or retracts from the wind outlet 11. The smooth section abuts against the first rack 33, and the first position of the air deflector 20 is kept still. When the air deflector assembly works, firstly, the gear section on the first driving gear 321 drives the first rack 33 to move, and the air deflector 20 is driven to extend out; when the air deflector 20 extends to the proper position, the smooth section of the first driving gear 321 abuts against the first rack 33, and at this time, the motor 31 continues to drive the step gear 32 to rotate, so that the second rack 34 outputs torque to drive the second position of the air deflector 20 to move relative to the first position of the air deflector 20 through the torque output by the second driving gear 322, thereby realizing the swinging air sweeping of the air deflector 20. Then, when the air deflector 20 needs to be retracted, the motor 31 drives the step gear 32 to rotate reversely until the gear section of the first driving gear 321 is meshed with the first rack 33, so as to drive the first rack 33 to move reversely, and then the motor is matched with the second rack 34 to retract the air deflector 20.
In the technical solution of the present embodiment, the ratio of the gear segment on the first driving gear 321 is smaller than the ratio of the smooth segment on the first driving gear 321. In this way, the air guide plate 20 can be guided with a larger swing width. Optionally, the ratio of the gear segment on the first driving gear 321 is 10% to 40%, and the ratio of the smooth segment on the first driving gear 321 is 60% to 90%. Preferably, the ratio of the gear segment on the first driving gear 321 is 1/3, and the ratio of the smooth segment on the first driving gear 321 is 2/3.
The technical scheme of the invention adopts multi-gear transmission, the gear transmission ratio is adjustable, the gravity moment of the air deflector 20 transmitted to the shaft of the motor 31 can be effectively reduced, the number of teeth of the small-pitch circular gear 351 and the large-pitch circular gear 352 in the stepped speed change gear 35 is 16. The number of teeth of the gear section on the first driving gear 321 is 48, and the gravity moment of the air deflector 20 finally transmitted to the shaft of the motor 31 is: 4.51 x 10^ (-3) G. By adopting the gear structure of the invention, the vibration and the noise of the motor 31 which are transmitted to the air deflector 20 can be reduced, and the noise problem of the wind sweeping motor 31 is further solved.
The invention also provides an air conditioning unit, which comprises an air conditioning body and the air deflector assembly, wherein the air conditioning body is provided with an air outlet 11, the air deflector assembly is arranged on the air outlet 11, and the air deflector assembly is the air deflector assembly. The air conditioning unit adopting the air guide plate assembly can effectively solve the condensation problem of the air guide plate 20, can realize that the single motor 31 controls the extension and air guide of the air guide plate 20, and reduces the cost and the noise generated during the operation of the motor.
