[0005] In the process of driving the motor to drive the guide vane to rotate, the rotation speed of the guide vane may be fast or slow, which affects the user's sensory experience. SUMMARY

[0006] To have a basic understanding of some aspects of the disclosed embodiments, a brief overview is given below. The summary is not an overall description of the application, nor is it intended to determine key / important elements or delineate the scope of these embodiments, but as a prelude to the detailed description below.

[0007] The movement mechanism for driving the guide vane to extend and rotate provided by the embodiments of the present disclosure can drive the guide vane to extend and rotate at a uniform speed by setting the outer convex bifurcated track, so as to improve the user's experience.

[0008] In some embodiments, the movement mechanism for driving the air deflector to extend and rotate includes a first connecting rod, a second connecting rod, and a track plate. One end of the first connecting rod is rotatably connected to the air deflector, and the first connecting rod includes a first limiting portion. One end of the second connecting rod is rotatably connected to the air deflector, and the second connecting rod includes a second limiting portion. The track plate is fixedly arranged on the air conditioner, and includes a first track and a second track. The first limiting portion is slidably arranged in the first track and the second track, and the second limiting portion is slidably arranged in the second track. The track plate is used to define the movement trajectory of the first connecting rod and the second connecting rod. The first track includes a bifurcated track in the shape of a person's hair. Each track of the bifurcated track is in the shape of an outward convex arc, so that the first connecting rod cooperates with the second connecting rod under the driving of an external force to drive the air deflector to extend out of the air conditioner and then rotate at a uniform speed.

[0009] Optionally, the bifurcated track includes a first branch track and a second branch track. The first branch track extends in one direction. The second branch track intersects the first branch track and extends in another direction. The radius of each of the first branch track and the second branch track is greater than or equal to 10° and less than or equal to 25°.

[0010] Optionally, the included angle between the tangent lines of the first branch track and the second branch track at the intersection point is greater than or equal to 50° and less than or equal to 80°.

[0011] Optionally, the first track further includes a first straight track. The first straight track is arranged at the upper part of the bifurcated track and communicates with the first branch track and the second branch track. The first straight track and the second track are both arranged in the direction in which the air deflector extends. The first connecting rod moves along the first straight track, and the second connecting rod moves along the second track, thereby synchronously driving the air deflector to first extend to a first preset position and then rotate at a uniform speed.

[0012] Optionally, the first straight track includes a straight segment and a transition segment. The transition segment is arranged at the communication position of the straight segment and the first branch track and the second branch track. The transition segment is used to avoid the air deflector from suddenly accelerating at the first preset position.

[0013] Optionally, the movement mechanism further includes a driving element. The driving element includes a first transmission shaft arranged at the free end of the driving element. The first connecting rod is provided with a through slot, and the first transmission shaft is slidably arranged in the through slot to provide a driving force for the movement of the first connecting rod.

[0014] Optionally, the driving element also includes a second transmission shaft, which is arranged between the rotating axis of the driving element and the first transmission shaft. The first connecting rod is also provided with a limiting groove. The second transmission shaft is slidably arranged in the limiting groove to make the first connecting rod move in a reverse direction, and then cooperate with the second connecting rod to drive the air guide plate to rotate at a uniform speed.

[0015] Optionally, the limiting groove is arranged at the lower side of the through groove and is communicated with the through groove.

[0016] The first track includes a first straight track, a first branch track and a second branch track that are interconnected. The first straight track includes a straight section and a transition section. The transition section is arranged at the connection between the straight section and the first branch track and the second branch track; the two ends of the inner edge of the limiting groove and the connection with the through groove are respectively provided with a first limiting section and a second limiting section. The first limiting section and the second limiting section are arc-shaped, so that the first connecting rod can slide smoothly from the end of the straight section into the starting end of the first branch track or the second branch track, so as to avoid the first connecting rod hitting the track plate and causing the air guide plate to jam.

[0017] In some embodiments, the air conditioner includes the above-mentioned motion mechanism for driving the air guide plate to extend and rotate.

[0018] The motion mechanism and air conditioner for driving the air deflector to extend and rotate provided in the embodiments of the present disclosure can achieve the following technical effects:

[0019] The motion mechanism provided by the disclosed embodiment includes a first connecting rod, a second connecting rod, and a track plate. The track plate is provided with a first track and a second track, wherein the first track includes a bifurcated track. The first limiting portion of the first connecting rod mates with both the first track and the second track, and the second limiting portion of the second connecting rod mates with the second track. Thus, the track plate can define the motion trajectories of the first and second connecting rods, so that the first connecting rod can drive the air deflector to rotate after extending from the air conditioner under the action of an external force. Furthermore, each track of the bifurcated track is arc-shaped and convex. In the disclosed embodiment, convex means that the center of each arc-shaped track of the bifurcated track is located inside the bifurcated track. Thus, the first limiting portion of the first connecting rod moves within the bifurcated track and cooperates with the second connecting rod to enable the air deflector to rotate at a constant speed after extending from the air conditioner, thereby preventing the air deflector from rapidly rotating upward or downward to open after extending from the air conditioner. This improves the accuracy of the motion mechanism in controlling the motion trajectory of the air deflector, thereby enhancing the user experience.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] The embodiment of the present disclosure provides an air conditioner, such as Figure 1 shown.

[0049] The air conditioner is a large guide plate type air conditioner. When the air conditioner guide vane 50 is in a closed state, the air outlet can be completely closed, and there is no gap between the guide vane 50 and the air outlet. Moreover, during the air supply process, the guide vane 50 first extends out of the air conditioner and then rotates to guide the air. In this way, the guide vane 50 is far away from the air outlet, and the air flow resistance of the air blown out of the air conditioner is small, which can reduce the noise generated at the guide vane 50 during the air supply process. At the same time, compared with the guide vane 50 rotating at the air outlet to supply air, the guide vane 50 rotating outside the air outlet can supply air at a larger angle and a larger range, thereby improving the cooling or heating effect of the air conditioner. Alternatively, the air conditioner provided by the embodiment of the present disclosure can also be a cabinet type air conditioner or a duct type air conditioner.

[0050] In some embodiments, the air conditioner comprises the above-mentioned movement mechanism for driving the guide vane 50 to extend and rotate.

[0051] Alternatively, the movement mechanism is arranged on both sides of the guide vane 50, and the movement mechanisms on both sides simultaneously drive the guide vane 50 to move. The following movement mechanism can drive the guide vane 50 to first extend out of the air outlet to a first preset position, and then drive the guide vane 50 to rotate at a constant speed. The structure and movement process of the movement mechanism are described in detail below.

[0052] The embodiment of the present disclosure also provides a movement mechanism for driving the guide vane 50 to extend and rotate, as shown in Figures 2 to 16

[0053] In some embodiments, the movement mechanism for driving the guide vane 50 to extend and rotate comprises a first connecting rod 20, a second connecting rod 30, and a track plate 40. One end of the first connecting rod 20 is rotationally connected with the guide vane 50, and the first connecting rod 20 comprises a first limiting portion. One end of the second connecting rod 30 is rotationally connected with the guide vane 50, and the second connecting rod 30 comprises a second limiting portion. The track plate 40 is fixedly arranged in the air conditioner, and the track plate 40 comprises a first track and a second track. The first limiting portion is slidingly arranged in the first track and the second track, and the second limiting portion is slidingly arranged in the second track. The track plate 40 is used to limit the movement trajectory of the first connecting rod 20 and the second connecting rod 30. The first track comprises a bifurcated track in the shape of a person's head. Each track of the bifurcated track is in the shape of an outward convex arc, so that the first connecting rod 20 cooperates with the second connecting rod 30 under the drive of an external force to drive the guide vane 50 to extend out of the air conditioner and then rotate at a constant speed.

[0054] ​The movement mechanism provided by the embodiments of the present disclosure comprises a first connecting rod 20, a second connecting rod 30 and a track plate 40, the track plate 40 is provided with a first track and a second track, the first track comprises a bifurcated track, the first limiting part of the first connecting rod 20 is matched with the first track and the second track at the same time, and the second limiting part of the second connecting rod 30 is matched with the second track. In this way, the movement trajectory of the first connecting rod 20 and the second connecting rod 30 can be limited by the track plate 40, so that the first connecting rod 20 can drive the air deflector 50 to rotate out of the air conditioner under the driving of external force. Meanwhile, each track of the bifurcated track is arc-shaped and outward convex, and in the embodiments of the present disclosure, the outward convexity means that the center of the circle where each arc-shaped track of the bifurcated track is located is located on the inner side of the bifurcated track. In this way, the first limiting part of the first connecting rod 20 moves in the bifurcated track, so that the air deflector 50 can rotate at a constant speed after extending out of the air conditioner, avoiding the situation that the air deflector 50 quickly rotates upward or downward after extending out of the air conditioner, improving the precision of the movement mechanism in controlling the movement trajectory of the air deflector 50, and further improving the user experience.

[0055] The structure of the track plate 40 in the embodiments of the present disclosure is shown in FIG. 1, which comprises a bifurcated track. Figure 3 The bifurcated track is in the shape of a herringbone, and each track of the bifurcated track is outward convex arc-shaped, that is, the center of the circle where each bifurcated track is located is located on the inner side of the bifurcated track. Figure 3 The inner side is the lower side of the herringbone bifurcated track.

[0056] The embodiments of the present disclosure also provide another structure of the track plate 40, as shown in FIG. 2. Figure 4 The bending directions of the bifurcated tracks of the herringbone in the two track plates 40 are different. Figure 4 As shown in FIG. 3, each track of the herringbone bifurcated track is also arc-shaped, but each track is inward concave arc-shaped, that is, the center of the circle where each bifurcated track is located is located on the outer side of the bifurcated track. Figure 4 The outer side is the upper side of the herringbone bifurcated track, which is different from Figure 3

[0057] The movement trajectories of the air deflector 50 driven by the bifurcated tracks in the two track plates 40 are different, and the bifurcated track in the herringbone shape can affect the rotating speed of the air deflector 50 after extending out of the air conditioner. Figure 3 The bifurcated track in the track plate 40 shown in FIG. 1 is outward convex, so that the air deflector 50 can rotate at a constant speed after extending out of the air conditioner. Figure 4 The bifurcated track in the track plate 40 shown in FIG. 3 is inward concave, so that the rotating speed of the air deflector 50 after extending out of the air conditioner will become faster and faster, and the air deflector 50 will quickly open upward or downward, directly affecting the sensory experience of the user.

[0058] ​In order to more intuitively reflect the rotating speed of the deflector 50 after the deflector 50 is extended out of the air conditioner, the present embodiment provides a rotating speed comparison diagram of the deflector 50 driven to rotate by the two kinds of track plates 40 Figure 6 . The rotating speed of the deflector 50 can be understood as an angular velocity of rotation.

[0059] As shown in Figure 6 , the solid line in the figure is the change trend of the rotating speed of the deflector 50 with time when the track plate 40 shown in Figure 3 is adopted. In the time period of 0-2 seconds, the rotating speed of the deflector 50 is 0, which indicates that the deflector 50 does not rotate during the extension process; in the time period of 2-4 seconds, the rotating speed of the deflector 50 begins to gradually increase, which indicates that the deflector 50 begins to rotate after being extended out of the air conditioner; in the time period of 4-10 seconds, the rotating speed of the deflector 50 remains unchanged, which indicates that the deflector 50 can basically maintain a uniform speed during the rotation process.

[0060] As shown in Figure 6 , the dashed line in the figure is the change trend of the rotating speed of the deflector 50 with time when the track plate 40 shown in Figure 4 is adopted. In the time period of 0-2 seconds, the rotating speed of the deflector 50 is 0, which indicates that the deflector 50 does not rotate during the extension process; in the time period of 2-4 seconds, the rotating speed of the deflector 50 begins to gradually increase, which indicates that the deflector 50 begins to rotate after being extended out of the air conditioner; in the time period of 4-10 seconds, the rotating speed of the deflector 50 gradually increases, which indicates that the speed of the deflector 50 during the rotation process is getting faster and faster.

[0061] By comparing the simulation experimental data of the two kinds of track plates 40 shown in Figure 6 , it can be seen from the rotating speed curve of the deflector 50 in the time period of 4-10 seconds that the track plate 40 provided by the present embodiment and having the bifurcated track with the outward convex shape can cooperate with other components of the movement mechanism to drive the deflector 50 to rotate at a uniform speed after the deflector 50 is extended out of the air conditioner, thereby avoiding the phenomenon that the deflector 50 rotates faster and faster during the rotation process and improving the sensory experience of the user.

[0062] Optionally, the bifurcated track includes a first branch track 42 and a second branch track 43, the first branch track 42 extends in one direction; the second branch track 43 intersects the first branch track 42 and extends in another direction; wherein the radii of the first branch track 42 and the second branch track 43 are both greater than or equal to 10° and less than or equal to 25°.

[0063] The V-shaped bifurcated track includes two intersecting branch tracks, namely the first branch track 42 and the second branch track 43. The two branch tracks extend in different directions like the left and right strokes of the Chinese character "人" (human). The first branch track 42 and the second branch track 43 both have a certain curvature and are convex outward. The curvature of the first branch track 42 and the second branch track 43 is greater than or equal to 10° and less than or equal to 25°. In this way, the air deflector 50 can rotate uniformly to the maximum opening angle after extending out of the air conditioner.

[0064] Optionally, the second track is arranged in a straight line along the direction in which the air deflector 50 extends and is located below the bifurcated track. The second limiting part is slidably arranged in the second track, and the first limiting part is slidably arranged in the first track and the second track. The first track and the second track jointly define the movement trajectory of the first connecting rod 20, and the second track can also define the movement trajectory of the second connecting rod 30.

[0065] Optionally, the second track includes three straight tracks, and the three straight tracks are arranged on the lower side of the bifurcated track. In this way, the linear motion of the second connecting rod 30 can be more stably defined.

[0066] Optionally, the included angle between the tangents of the first branch track 42 and the second branch track 43 at the intersection point is greater than or equal to 50° and less than or equal to 80°.

[0067] As Figure 5 shown, Figure 5 is a schematic diagram of the bifurcated track. The first branch track 42 and the second branch track 43 have an intersection point O. The tangent of the first branch track 42 at point O is OM, and the tangent of the second branch track 43 at point O is ON. The angular range of the included angle between the tangent OM and the tangent ON is: 50° ≤ α ≤ 80°. The included angle between the tangent OM of the first branch track 42 at point O and the tangent ON of the second branch track 43 at point O affects the rotation speed of the air deflector 50 rotating uniformly after extending out of the air conditioner. When the angle of the included angle α is too large, the rotation speed of the air deflector 50 rotating uniformly is too large, resulting in the air deflector 50 opening upward or downward too fast. When the included angle α is too small, there is not enough arrangement space for the three straight tracks of the second track. When the angle of the included angle α is within the above range, the air deflector 50 has a suitable rotation speed for uniform rotation, making the speed of the air deflector 50 opening upward or downward more reasonable.

[0068] Optionally, the first track further comprises a first straight track 41 arranged at the upper portion of the bifurcated track and communicating with the first branch track 42 and the second branch track 43, the first straight track 41 and the second track are arranged along the direction in which the deflector 50 extends; wherein the first connecting rod 20 moves along the first straight track 41, the second connecting rod 30 moves along the second track, thereby synchronously driving the deflector 50 to first extend to the first preset position, and then rotate at a constant speed.

[0069] In the embodiments of the present disclosure, the first preset position is a position at which the deflector 50 is translated to extend out of the air conditioner and is about to start rotating, as shown in Figure 14 At this time, the deflector 50 has a certain distance from the air outlet, and the deflector 50 can be opened upward or downward at the first preset position. In the embodiments of the present disclosure, the rotating position of the deflector 50 is not limited to the first preset position, and the first preset position is the initial position of the deflector 50 rotating, and the rotation of the deflector 50 can be understood as extending and rotating at the same time.

[0070] Optionally, the first limiting portion comprises at least two sliding columns. Optionally, the two sliding columns are respectively slidingly arranged in the first track and the second track.

[0071] As shown in Figure 9 The first limiting portion comprises a first sliding column 25 and a second sliding column 26, the first sliding column 25 is arranged at the top end of the first connecting rod 20, and the second sliding column 26 is arranged at the middle portion of the first connecting rod 20. The first sliding column 25 is slidingly arranged in the first track, and the second sliding column 26 is slidingly arranged in one of the straight tracks of the second track. When the first sliding column 25 moves from the first straight track 41 to the first branch track 42 or the second branch track 43, the second connecting rod 30 always moves linearly along the second track, the first connecting rod 20 will produce relative motion with the second connecting rod 30, the first connecting rod 20 changes the direction of motion, and then cooperates with the second connecting rod 30 to drive the deflector 50 to rotate at a constant speed.

[0072] Optionally, the second limiting portion comprises at least three sliding columns, and the sliding columns are slidingly arranged in the second track.

[0073] As shown in Figure 10 The second limiting portion of the second connecting rod 30 comprises a third sliding column 31, a fourth sliding column 32 and a fifth sliding column 33, and the three sliding columns are arranged in a triangular shape. In this way, the limiting effect of the track plate 40 on the movement track of the second connecting rod 30 is improved.

[0074] Optionally, the second track comprises a second straight track 44, a third straight track 45 and a fourth straight track 46, and the second connecting rod 30 moves linearly along the three straight tracks during the extension and rotation of the deflector 50. The third sliding column 31 moves in the second straight track 44, the fourth sliding column 32 moves in the third straight track 45, and the fifth sliding column 33 moves in the fourth straight track 46.

[0075] Optionally, the second straight track 44, the third straight track 45 and the fourth straight track 46 are track grooves penetrating the track plate 40. In this way, the second sliding column 26 and the three sliding columns of the second limiting part can stably slide in the track grooves, improving the stability of the connecting rod moving in the track.

[0076] Optionally, the first straight track 41 comprises a straight section and a transition section, and the transition section is arranged at the communication between the straight section and the first branch track 42 and the second branch track 43, and is used to avoid the sudden acceleration of the deflector 50 at the first preset position.

[0077] As shown in FIG. 1, Figure 3 the first straight track 41 comprises a straight section and a transition section which are in communication with each other, and the transition section is in communication with the first branch track 42 and the second branch track 43, Figure 3 the straight section and the transition section are schematically shown by dashed lines, the upper part of the first straight track 41 is the straight section, and the part surrounded by the dashed lines in the lower part of the first straight track 41 is the transition section.

[0078] If the first straight track 41 does not have the transition section, the rotation speed of the deflector 50 will suddenly increase at the first preset position. In order to intuitively reflect the influence of the transition section on the rotation speed of the deflector 50, the present embodiment provides a comparison diagram of the rotation speed of the deflector 50 in the case where the first straight track 41 has the transition section and in the case where the first straight track 41 does not have the transition section.

[0079] As shown in FIG. 2, Figure 7 the solid line in the figure is the change trend of the rotation speed of the deflector 50 with time in the case where the first straight track 41 has the transition section. In the first 2 seconds, the rotation speed of the deflector 50 is 0, indicating that the deflector 50 does not rotate during the extension; in the 2-4 seconds, the rotation speed of the deflector 50 begins to gradually increase, indicating that the deflector 50 begins to gradually rotate after being extended out of the air conditioner; in the 4-10 seconds, the rotation speed of the deflector 50 remains unchanged, indicating that the deflector 50 can maintain a uniform speed during the rotation.

[0080] As shown in FIG. 3, Figure 7As shown in the figure, the dotted line shows the change in the rotational speed of the air deflector 50 over time when the first linear track 41 is not provided with a transition section. During the time period of 0-3.5 seconds, the rotational speed of the air deflector 50 is 0, indicating that the air deflector 50 does not rotate during the extension process. At 3.5 seconds, the rotational speed of the air deflector 50 suddenly increases, indicating that the air deflector 50 suddenly accelerates after being extended from the air conditioner. During the time period of 3.5-10 seconds, the rotational speed of the air deflector 50 remains essentially unchanged, indicating that the air deflector 50 maintains a constant speed after the sudden acceleration.

[0081] Through the above Figure 7 The comparison of simulation test data with and without a transition section on the first linear track 41 shown in the figure shows that from the rotation speed of the air guide plate 50 in the time period of 2-4 seconds, it can be seen that after the transition section is set on the first linear track 41, the air guide plate 50 can gradually start to rotate from the translationally extended state without sudden acceleration, thereby improving the user's sensory experience and improving the degree of precise control over the movement process of the air guide plate 50.

[0082] Optionally, the time ratio of the first sliding column 25 of the first connecting rod 20 moving in the straight section, the transition section and the first branch track 42 or the second branch track 43 is (1-2): (2-4): (5-7). In this way, the air guide plate 50 can be extended to a suitable distance before rotating, so as to prevent the air guide plate 50 from hitting the housing of the air conditioner. In addition, by limiting the time ratio of the first sliding column 25 in the three sections of the first track, the rotation speed of the air guide plate 50 can also be made moderate. For example, the time ratio of the first sliding column 25 moving in the straight section, the transition section and the first branch track 42 or the second branch track 43 can be 1.6:2.4:6, or 1.3:2.5:6.5, etc.

[0083] Optionally, the second connecting rod 30 is further provided with a through slide 35 that penetrates the plate surface of the second connecting rod 30. The provision of the through slide 35 on the second connecting rod 30 enables the second sliding post 26 of the first connecting rod 20 to pass through the through slide 35 and move along the second track.

[0084] Optionally, the first connecting rod 20 and the second connecting rod 30 are both rotatably connected to the wind deflector 50.

[0091] In the motion process of the air deflector 50, when the first sliding column 25 of the first connecting rod 20 moves to the transition section, the transition section has no track constraint force on the first sliding column 25. In this way, the first connecting rod 20 may not move along the first branch track 42 or the second branch track 43 due to gravity. In this way, the limiting slot 23 can be arranged on the first connecting rod 20, and the abutting force generated between the second transmission shaft 122 and the limiting slot 23 provides the driving force for the first sliding column 25 of the first connecting rod 20 to select the first branch track 42 or the second branch track 43.

In this way, during the movement of the first transmission shaft 121 driving the first connecting rod 20, the second transmission shaft 122 can slide from the limiting groove 23 to the upper side of the through groove 21 through the through groove 21, without interfering with the movement of the first connecting rod 20.

[0093] Optionally, the two ends of the inner edge of the limiting groove 23 are respectively provided with a first limiting section and a second limiting section at the communication positions with the through groove 21, and the first limiting section and the second limiting section are arc-shaped, so that the first connecting rod 20 smoothly slides from the end of the straight section to the starting end of the first branch track 42 or the second branch track 43, avoiding the impact of the first connecting rod 20 on the track plate 40 causing the jamming of the movement of the air deflector 50.

Optionally, the first limiting section AC and the second limiting section BD are arc-shaped sections, so that the first sliding column 25 of the first connecting rod 20 can smoothly slide from the straight section of the first straight track 41 to the first branch track 42 or the second branch track 43, without impacting the track between the E and F points of the track plate 40 shown in Figure 3 , avoiding the impact on the track plate 40 to cause the jamming of the movement of the air deflector 50, and improving the smoothness of the movement of the air deflector 50.

[0096] Specifically, when the second transmission shaft 122 moves along the first limiting section AC, the first limiting column smoothly slides from the end of the straight section of the first straight track 41 to the E point along the circular arc R1, and then enters the first branch track 42. When the second transmission shaft 122 moves along the second limiting section BD, the first limiting column smoothly slides from the end of the straight section to the F point along the circular arc R2, and then enters the second branch track 43.

[0097] Optionally, the first flared section 231 has a first limiting point A, and the second flared section 232 has a second limiting point B. The drive force for the movement of the first connecting rod 20 is provided by the abutting force between the second transmission shaft 122 and the first limiting point A and the second limiting point B. The abutting force between the second transmission shaft 122 and the first limiting point A or the second limiting point B provides the drive force for the first sliding column 25 of the first connecting rod 20 to select the first branch track 42 or the second branch track 43 for movement.

[0098] In the embodiments of the present disclosure, the shape of the first track of the herringbone shape on the track plate 40 is changed, and the shapes of the first branch track 42 and the second branch track 43 are the outward convex shapes as shown in the figure, rather than the inward concave shapes as shown in the figure.

Thus, the positions of the first limiting point and the second limiting point on the limiting groove 23 are changed.

The first end of the rotating rod 12 is fixedly connected to the notch 111, and the second end of the rotating rod 12 is a free end.

[0101] Optionally, the crank is drivingly connected with a motor. The driving shaft of the motor is arranged at the rotation center of the crank.

[0103] ​​​​​Optionally, the crank also includes a second transmission shaft 122, which is used to drive the first connecting rod 20 to change direction. The second transmission shaft 122 is disposed on the rotating surface of the rotating rod 12 and is located between the first end of the rotating rod 12 and the first transmission shaft 121. The second transmission shaft 122 can provide the driving force for the first connecting rod 20 to select the track.

[0104] The motion mechanism for driving the air deflector 50 to extend and rotate provided in the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

[0105] The initial state of the motion mechanism of the air guide plate 50 in the closed state is as follows: Figure 2 As shown. When the driving element 10 is Figure 2 When the initial position shown rotates in the first direction or the second direction, the first transmission shaft 121 slides in the through slot 21 of the first connecting rod 20 to drive the first connecting rod 20 and the second connecting rod 30 to move. The first connecting rod 20 moves linearly along the straight section of the first linear track 41, and the second connecting rod 30 moves linearly along the second track, thereby driving the air deflector 50 to move linearly and extend to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to when the first sliding column 25 of the first connecting rod 20 moves to the end of the straight section. In the embodiment of the present disclosure, the first direction is based on Figure 2 The first direction is clockwise and the second direction is counterclockwise.

[0106] When the driving element 10 rotates in the first direction and the air guide plate 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 moves to the first limit point A. Since there is a contact force between the second transmission shaft 122 and the first limit point A, the first sliding column 25 of the first connecting rod 20 is provided with a driving force to select the first branch track 42. When the second transmission shaft 122 continues to move to point C, the first sliding column 25 slides smoothly along the arc R1 to point E. After that, the driving element 10 continues to rotate, the first sliding column 25 enters the first branch track 42, the first connecting rod 20 and the second connecting rod 30 generate relative movement, and then jointly drive the air guide plate 50 to open upward, as shown in FIG. Figure 15 shown.

[0107] When the driving element 10 rotates in the second direction and the air guide plate 50 reaches the first preset position, the second transmission shaft 122 of the driving element 10 moves to the second limit point B. Due to the abutment force between the second transmission shaft 122 and the second limit point B, the first sliding column 25 of the first connecting rod 20 is provided with a driving force to select the second branch track 43. When the second transmission shaft 122 continues to move to point D, the first sliding column 25 slides smoothly along the arc R2 to point F. After that, the driving element 10 continues to rotate, the first sliding column 25 enters the second branch track 43, the first connecting rod 20 and the second connecting rod 30 generate relative movement, and then jointly drive the air guide plate 50 to open downward, as shown in FIG.Figure 16 are shown.
