DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Example 1, refer to the attached Figure 1-13 , an air-conditioning outlet assembly, comprising:

[0029] Housing 10;

[0030] The first blade assembly 20 is disposed in the housing 10 and includes a rotatable first active blade 21, a plurality of first driven blades 22 and a first connecting rod 23. The first active blade 21 drives the first driven blades 22 to rotate synchronously through the first connecting rod 23;

[0031] The second blade assembly 30 is disposed in the housing 10 and includes a rotatable second active blade 31, a plurality of second driven blades 32 and a second connecting rod 33. The second active blade 31 drives each second driven blade 32 to rotate synchronously through the second connecting rod 33. The first blade assembly 20 and the second blade assembly 30 are arranged in parallel along the length direction thereof;

[0032] The transmission mechanism is arranged outside the housing 10, and includes a rotating member 40, a first transmission assembly 50 and a second transmission assembly 60; the rotating member 40 is arranged at a middle position between the first blade assembly 20 and the second blade assembly 30, and a closed path track path 41 is arranged on the rotating member 40; the first transmission assembly 50 includes a first crank 51, the first crank 51 includes a first linkage portion 511 and a first shaft portion 512, the first linkage portion 511 is arranged to be able to move along the track path 41, and the first shaft portion 512 is arranged to be able to connect to the shaft of the first active blade 21; the second transmission assembly 60 includes a second crank 61, the second crank 61 includes a second linkage portion 611 and a second shaft portion 612, the second linkage portion 611 is arranged to be able to move along the track path 41, and the second shaft portion 612 is arranged to be able to connect to the shaft of the second active blade 31; in this embodiment, the track path 41 is a track groove, and the first linkage portion 511 and the second linkage portion 611 are both sliding columns that extend into the track groove and can cooperate with the track groove;

[0033] The trajectory path 41 includes at least 4 node positions 411 that can make the active blades at the extreme wind outlet angle. Any two adjacent node positions 411 can form a node angle with the center of the rotating member 40 as the intersection point, and the angles of the node angles are the same; when the first linkage part 511 and the second linkage part 611 respectively run to a node position 411 in the trajectory path 41, the first linkage part 511 and the second linkage part 611 can form a fixed angle with the center of the rotating member 40 as the intersection point, and the angle value of the fixed angle is an integer multiple of the angle value of the node angle;

[0034] The driving motor 70 is configured to drive the rotating member 40 to rotate, and the rotation of the rotating member 40 can drive the first active blade 21 and the second active blade 31 to rotate through the first crank 51 and the second crank 61 respectively. The angle change of the first active blade 21 and the second active blade 31 is determined by the shape of the trajectory path 41.

[0035] The air outlet assembly of the air conditioner in this embodiment can drive two sets of blade assemblies to achieve a preset air outlet direction through only a single driving mechanism, which can save the cost of a driving mechanism, and the overall components are few, the structure is compact, and the cost is low. In addition, according to the change of the trajectory path 41, the air outlet angles or modes of the air conditioner outlet assembly can be switched.

[0036] A specific implementation method, such as Figure 6-13 As shown, the left side is the first blade assembly 20, and the right side is the second blade assembly 30. The number of node positions 411 of the trajectory path 41 is 4, and the angle of each node angle is 90°. Each node position 411 corresponds to an extreme wind outlet angle. The extreme wind outlet angles corresponding to the four node positions 411 are right, left, left, and right, respectively. The first linkage part 511 and the second linkage part 611 form a fixed angle of 90° (i.e., a node position difference) with the center of the rotating part 40 as the intersection point. When the rotating part 40 rotates counterclockwise, the wind outlet angle or mode of the air-conditioning outlet assembly can reach the preset concentrated wind outlet, left wind outlet, dispersed wind outlet, and right wind outlet. The wind direction of the two sets of blade assemblies and the change of the wind outlet angle of the air-conditioning outlet assembly are shown in the following table:

[0037] In another specific implementation, the number of node positions 411 of the trajectory path 41 is 5, and the angle of each node is 72°. Each node position 411 corresponds to an extreme wind outlet angle, and the extreme wind outlet angles corresponding to the 5 node positions 411 are right, left, left, right, left or left, right, right, left, right, respectively. The first linkage part 511 and the second linkage part 611 form a fixed angle of 144° (i.e., the difference between the two node positions) with the center of the rotating member 40 as the intersection point. When the rotating member 40 rotates counterclockwise, the wind outlet angle or mode of the air-conditioning outlet assembly can reach the preset concentrated wind outlet, left wind outlet, dispersed wind outlet and right wind outlet. The changes in the wind outlet angles of the two sets of blade assemblies and the air-conditioning outlet assembly are shown in the following table:

[0038] It can be seen that in the air-conditioning air outlet assembly of the aforementioned embodiment, when the position of the rotating member 40 is reciprocated between P1 and P2, the air-conditioning air outlet assembly can realize a sweeping wind mode of concentrated air outlet → middle air outlet → dispersed air outlet → middle air outlet → concentrated air outlet; when the position of the rotating member 40 is reciprocated between P3 and P4, the air-conditioning air outlet assembly can realize a left-right sweeping wind mode of left air outlet → middle air outlet → right air outlet → middle air outlet → left air outlet.

[0039] Example 2, refer to the attached Fig.14 The main structure of the air outlet assembly of the air conditioner in this embodiment is the same as that of the embodiment 1, and the main difference lies in the position of the rotating member 40 and the structure of the first transmission assembly 50. Specifically:

[0040] The rotating member 40 is arranged at a non-middle position between the first blade assembly 20 and the second blade assembly 30; the first transmission assembly 50 includes a first active crank 52, a first driven crank 54 and a crank connecting rod 53, which are connected to form a parallelogram double crank mechanism, the first active crank 52 has a first linkage portion 511, the first driven crank 54 has a first rotating shaft portion 512, and the first rotating shaft portion 512 is connected to the rotating shaft of the first active blade 21; the crank connecting rod 53 can keep the first active crank 52 and the first driven crank 54 at the same rotation angle.

[0041] Compared with Example 1, although the cost of a crank member and a connecting rod member is increased, the drive motor 70 and the rotating member 40 in Example 1 can only be arranged in the middle position between the first blade assembly 20 and the second blade assembly 30, while the installation position of the drive motor 70 and the rotating member 40 in this embodiment is more flexible and more suitable for vehicles with limited installation space in the vehicle.

[0042] Although the present invention has been described with reference to preferred embodiments, it should be understood by those skilled in the art that it is not limited to the description of the above embodiments and that various changes in form and details may be made within the scope of the claims.
