Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to a driving mechanism for an air guide plate of an air conditioner and an air conditioner. Background Art

[0002] Currently, the air deflector in an air conditioner's indoor unit is typically connected to a push-out mechanism. This mechanism pushes the deflector's center of rotation outward to prevent interference with the air conditioner panel during rotation, thereby enabling the deflector to rotate at a wide angle. When air is needed, the push-out mechanism pushes the deflector outward, and the deflector's rotation mechanism drives the deflector to rotate, allowing it to deliver air upward or downward.

The ejection structure is movably mounted on the base and has a retracted position and an extended position. The air deflector is rotatably mounted on the end of the ejection structure. The first drive unit is mounted on the ejection structure to drive the air deflector in rotation. A predetermined distance exists between the axis of the air deflector and the first drive unit, and the first drive unit drives the air deflector in rotation via a transmission mechanism.

[0049] 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.

[0050] An embodiment of the present disclosure provides an air conditioner.

[0051] The air conditioner is a large-guide-plate air conditioner. When the air guide plate 50 of the air conditioner is in the closed state, the air outlet can be completely closed, and there is no gap between the air guide plate 50 and the air outlet. In addition, during the air supply process of the air conditioner, the air guide plate 50 is first extended from the air conditioner and then rotated to guide the air. In this way, the air guide plate 50 is far away from the air outlet, and the wind resistance of the air flow blown out of the air conditioner is small, which can reduce the noise generated at the air guide plate 50 during the air supply process. At the same time, compared with the air guide plate 50 rotating at the air outlet to supply air, the air guide plate 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. Optionally, the air conditioner provided in the embodiment of the present disclosure can also be a cabinet unit or a duct unit.

[0052] In some embodiments, the air conditioner includes a driving mechanism for extending and rotating the air guide plate.

[0053] Optionally, a drive mechanism is provided on each side of the air deflector 50, and the drive mechanisms on both sides simultaneously drive the air deflector 50 to move. The drive mechanism described below can first extend the air deflector 50 out of the air outlet to a first preset position, and then drive the air deflector 50 to rotate at a constant speed. The structure and movement of the drive mechanism are described in detail below.

[0054] The embodiment of the present disclosure also provides a driving mechanism for driving the air guide plate 50 to extend and rotate, such as Figures 1 to 14 shown.

[0055] The driving mechanism for the air deflector 50 provided in the embodiment of the present disclosure includes a crank 10, an active connecting rod 20, and a passive connecting rod 30. The crank 10 is provided with a first rotating shaft 11. One end of the active connecting rod 20 is rotatably connected to the air deflector 50. The active connecting rod 20 is provided with a sliding groove for sliding the first rotating shaft 11, so that the active connecting rod 20 moves under the drive of the crank 10. One end of the passive connecting rod 30 is rotatably connected to the air deflector 50, and the passive connecting rod 30 moves under the drive of the active connecting rod 20. The active connecting rod 20 and the passive connecting rod 30 drive the air deflector 50 to extend and close the air outlet of the air conditioner indoor unit.

[0056] The drive mechanism provided in the disclosed embodiment includes a crank 10, an active connecting rod 20, and a passive connecting rod 30. The crank 10 can be rotated by a stepper motor. The first rotation axis 11 of the crank 10 slides along the guide groove of the active connecting rod 20, thereby driving the active connecting rod 20, which in turn drives the passive connecting rod 30. The drive mechanism provided in the disclosed embodiment can simultaneously drive the air deflector 50 to extend and rotate, simplifying the structure of the air deflector 50 drive mechanism.

[0057] Optionally, the chute is curved.

[0058] Figure 5 A linear slide 27 is shown. The first rotating shaft 11 of the crank rotates along its rotation center 12 to generate a circular motion trajectory. When the first rotating shaft 11 performs circular motion and slides in the linear slide 27, it generates a driving force on the active connecting rod 20. However, under the action of this driving force, the extension speed of the air guide plate 50 driven by the active connecting rod 20 and the driven connecting rod 30 is as follows: Figure 12 As shown. Figure 12 It can be seen that under the driving force generated by the movement of the first rotating shaft 11 of the crank along the linear slide groove 27, the speed at which the active connecting rod 20 and the driven connecting rod 30 drive the air guide plate 50 to extend gradually changes, and the uniformity is poor, which in turn affects the stability of the extension of the air guide plate 50.

[0059] The chute provided in the disclosed embodiment is a curved chute, allowing the first rotating shaft 11 of the crank to move along the curved chute. This improves the uniformity of the linear driving force generated by the movement of the first rotating shaft 11, allowing the active connecting rod 20 and the driven connecting rod 30 to extend the air deflector 50 at a relatively uniform speed, thereby improving the stability of the air deflector 50 during its extension. It is understood that the drive mechanism provided in the disclosed embodiment can simultaneously extend and rotate the air deflector 50. The "rotation" process herein is accompanied by the extension of the air deflector 50, that is, the rotation herein can be understood as "rotation while extending." The curved chute provided in the disclosed embodiment improves the uniformity of the extension speed of the air deflector 50. The "extension speed" herein includes the extension speed of the air deflector 50 during linear extension as well as the extension speed of the air deflector 50 during rotation. The curved chute provided in the disclosed embodiment improves the uniformity of the "extension speed" of the air deflector 50 throughout its entire motion, thereby improving the stability of the air deflector 50 throughout its entire motion. Optionally, the direction of the driving force generated by the first rotating shaft of the crank is the same as the direction in which the air deflector extends linearly. Similarly, the first rotating shaft of the crank is reversed to drive the air deflector to retract to the air outlet.

[0060] Optionally, a "curved chute" may be understood as a chute having a partially or entirely curved shape. A curve may be understood as a line with an arc, such as a regular circular arc, an elliptical arc, or other irregularly curved lines.

[0061] Alternatively, the curved chute may be an elliptical chute. For example, it may be formed by connecting two semi-elliptical shapes. Optionally, the arc lengths of the two semi-elliptical shapes are unequal. This further improves the uniformity of the propulsion force generated by the first rotating shaft 11 and enhances the stability of the air deflector 50 during its extension.

[0062] Optionally, the curved chute includes a first curved segment, which includes a first upper curved segment 21 and a first lower curved segment 22. The first lower curved segment 22 is connected to the first upper curved segment 21 in a curved manner, and is disposed below a corresponding position of the first upper curved segment 21.

[0063] like Figure 3 As shown, the first curved segment is composed of a first upper arc segment 21 and a first lower arc segment 22 that are connected to each other. Optionally, the bending directions of the first upper arc segment 21 and the first lower arc segment 22 are opposite to each other, further improving the uniformity of the extension speed of the air guide plate 50. Figure 3 As shown, the first upper arc segment bends downward, and the first lower arc segment bends upward.

[0064] Optionally, the arc length of the first upper arc segment 21 is greater than the arc length of the first lower arc segment 22 .

[0065] The two arc segments are of unequal length, and the arc length of the first upper arc segment 21 is greater than the arc length of the first lower arc segment 22. When the first rotating shaft 11 of the crank moves along the first upper arc segment 21, the active connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to extend linearly. Simultaneously, the first rotating shaft 11 continues to move along the first upper arc segment 21, and the active connecting rod 20 and the driven connecting rod 30 can drive the air deflector 50 to rotate. When the first rotating shaft 11 of the crank moves to the first lower arc segment 22, the active connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to continue rotating until the air deflector 50 opens to the set angle or the maximum angle.

[0066] Optionally, the first upper arc segment 21 is semi-elliptical, and the first lower arc segment 22 is semi-elliptical.

[0067] The first upper arc segment 21 and the first lower arc segment 22 are both semi-elliptical, and the arc length of the first upper arc segment 21 is greater than the arc length of the first lower arc segment 22. Figure 3As shown. This further improves the uniformity of the linear thrust generated by the first rotating shaft 11 and enhances the stability of the air deflector 50 during its extension. Optionally, the first upper arc segment 21 includes a first endpoint connected to the second upper arc segment 23 and a second endpoint connected to the first lower arc segment 22. The linear distance between the first and second endpoints of the first upper arc segment 21 is equal to the radius of the circle formed by the rotation of the first rotating shaft 11 of the crank. This allows the first rotating shaft 11 to smoothly move through the first upper arc segment 21 to the first lower arc segment 22.

[0068] Optionally, the curved chute further includes a second curved segment symmetrical to the first curved segment, the second curved segment including a second upper curved segment 23 and a second lower curved segment 24. The second lower curved segment 24 is bent and connected to the second upper curved segment 23, and is disposed below a corresponding position of the second upper curved segment 23. The first upper curved segment 21 is connected to the second upper curved segment 23.

[0069] Similarly, the arc length of the second upper arc segment 23 is greater than the arc length of the second lower arc segment 24 .

[0070] The two arc segments are of unequal length, and the arc length of the second upper arc segment 23 is greater than the arc length of the second lower arc segment 24. When the first rotating shaft 11 of the crank moves along the second upper arc segment 23, the active connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to extend linearly. Simultaneously, the first rotating shaft 11 continues to move along the second upper arc segment 23, and the active connecting rod 20 and the driven connecting rod 30 can drive the air deflector 50 to rotate. When the first rotating shaft 11 of the crank moves to the second lower arc segment 24, the active connecting rod 20 and the driven connecting rod 30 drive the air deflector 50 to continue rotating until the air deflector 50 opens to the set angle or the maximum angle.

[0071] Optionally, the second upper arc segment 23 is semi-elliptical, and the second lower arc segment 24 is semi-elliptical.

[0072] The second upper arc segment 23 and the second lower arc segment 24 are both semi-elliptical, and the arc length of the second upper arc segment 23 is greater than the arc length of the second lower arc segment 24. Figure 3 As shown. This further improves the uniformity of the linear thrust generated by the first rotating shaft 11 and enhances the stability of the air deflector 50 during its extension. Optionally, the second upper arc segment 23 includes a third endpoint connected to the first upper arc segment 21 and a fourth endpoint connected to the second lower arc segment 24. The linear distance between the third and fourth endpoints of the second upper arc segment 23 is equal to the radius of the circle formed by the rotation of the first rotating shaft 11 of the crank. This allows the first rotating shaft 11 to smoothly move through the second upper arc segment 23 to the second lower arc segment 24.

[0073] Optionally, the arc length and radian of the first upper arc segment 21 are equal to those of the second upper arc segment 23, and the arc length and radian of the first lower arc segment 22 are equal to those of the second lower arc segment 24. The curved chute includes a first curved segment and a second curved segment that are symmetrically arranged and interconnected, and can also be called a hyperbolic chute. When the first rotating shaft 11 of the crank slides along the first upper arc segment 21 and the first lower arc segment 22 of the first curved segment, the air guide plate 50 opens upward; when the motor reverses and the first rotating shaft 11 of the crank slides along the second upper arc segment 23 and the second lower arc segment 24 of the second curved segment, the air guide plate 50 opens downward. Optionally, the curved chute is butterfly-wing shaped, such as Figure 3 shown.

[0074] The first rotation axis 11 of the crank is along Figure 3 When the butterfly-shaped chute shown in FIG. 1 slides, the active link 20 and the driven link 30 drive the air guide plate 50 to move at an extension speed as shown in FIG. Figure 13 As shown. Figure 13 As can be seen from the figure, the extension speed of the air deflector 50 is relatively uniform throughout the entire movement process. Compared with the linear slide 27, the butterfly-wing slide provided by the embodiment of the present disclosure greatly improves the uniformity of the extension speed of the air deflector 50 throughout the entire movement process, thereby improving the stability of the air deflector 50 during the extension process.

[0075] Optionally, the shape of the chute is obtained by fitting a motion trajectory of the first rotating shaft 11 on the active connecting rod 20 during the extension and rotation of the air guide plate 50 .

[0076] like Figure 5 As shown, when the shape of the chute is limited to a linear shape, the propulsion force generated by the first rotating shaft 11 of the crank sliding in the linear chute 27 pushes the air deflector 50 to extend at a relatively uniform speed throughout the entire movement process, affecting the stability of the air deflector 50 during the movement process. In the disclosed embodiment, the shape of the chute is obtained by fitting the motion trajectory of the first rotating shaft 11 of the crank on the active connecting rod 20 during the extension and rotation of the air deflector 50. This makes the shape of the chute and its location on the active connecting rod 20 more consistent with the requirements for uniform speed, extension distance, rotation angle, etc. during the extension and rotation of the air deflector 50, thereby improving the stability and controllability of the air deflector 50 during the entire movement process.

[0077] Optionally, the shape of the slide is obtained by fitting the motion trajectory of the first rotating shaft on the active connecting rod 20 during the extension and rotation of the air guide plate 50, including: controlling the air guide plate 50 to extend and rotate at a uniform speed, and the motion trajectory formed by the first rotating shaft 11 on the active connecting rod 20 is the shape of the slide.

[0078] On the basis of defining the uniform extension and rotation of the air deflector 50, the motion trajectory formed by the first rotation axis on the active connecting rod 20 is used as the shape of the chute, further improving the accuracy of the definition of the chute shape, thereby improving the uniformity and stability of the air deflector 50 throughout the entire movement process. It should be understood that the "uniform rotation" here refers to the uniformity of the speed of linear extension included in the extension and rotation.

[0079] Optionally, the air guide plate 50 is controlled to extend and rotate at a uniform speed, and the motion trajectory formed by the first rotating shaft 11 on the active connecting rod 20 is the shape of a slide groove, including: controlling the air guide plate 50 to extend at a uniform speed and open upward at a uniform speed, and the motion trajectory formed by the first rotating shaft 11 on the active connecting rod 20 is a part of the shape of the slide groove; controlling the air guide plate 50 to extend at a uniform speed and open downward at a uniform speed, and the motion trajectory formed by the first rotating shaft 1 on the active connecting rod 20 is another part of the shape of the slide groove.

[0080] When the air deflector 50 is controlled to extend and open upward at a uniform speed, the motion trajectory of the first rotating shaft 11 on the active connecting rod 20 forms a portion of the chute shape. When the motor is controlled to reverse, the air deflector 50 is controlled to extend and open downward at a uniform speed, the motion trajectory of the first rotating shaft on the active connecting rod 20 forms another portion of the chute shape. The chute shape provided by the disclosed embodiment improves the uniformity and stability of the entire motion process of the air deflector 50 during both upward and downward opening.

[0081] Optionally, the shape of the chute obtained by fitting is a butterfly wing shape, such as Figure 3 As shown, after the first rotating shaft 11 of the crank slides in the butterfly-wing type slot, the extension speed of the air guide plate 50 during the entire movement process is as follows: Figure 13 It can be seen that the shape of the chute obtained by fitting provided by the embodiment of the present disclosure greatly improves the uniformity and stability of the air guide plate 50 during its movement.

[0082] Optionally, the active connecting rod 20 is provided with a curved chute for sliding the first rotating shaft 11 of the crank. The curved chute includes a first upper arc segment and a first lower arc segment that are connected by a bend. The air deflector 50 movement mechanism also includes an electromagnetic element. The active connecting rod 20 is provided with an attraction element that can be attracted by the electromagnetic element. The electromagnetic element is configured to attract the attraction element when energized, causing the first rotating shaft to slide along the lower arc segment of the curved chute.

[0083] In the initial state, the first rotation axis 11 of the crank is located at the first end point of the upper arc segment. Figure 1As shown. The first rotating shaft 11 of the crank slides along the upper arc segment, driving the air deflector 50 to extend linearly to the first preset position, and then continues to drive the air deflector 50 to rotate. When the first rotating shaft 11 rotates to the connection point between the upper and lower arc segments, the active connecting rod 20 tends to sink due to the gravity of the active connecting rod 20. At this time, the first rotating shaft 11 tends to continue to slide preferentially along the upper arc segment, rather than sliding along the lower arc segment as set. This affects the uniformity and stability of the air deflector 50's rotation process, and may even cause the air deflector 50 to freeze during rotation, affecting its normal movement. In the driving mechanism provided by the embodiment of the present disclosure, an electromagnetic element 44 is provided. When the first rotating shaft 11 of the crank slides to the connection point of the first upper arc segment and the first lower arc segment, the electromagnetic element 44 is controlled to be energized to attract the attraction element provided on the active connecting rod 20. The attraction of the electromagnetic element 44 overcomes the sinking tendency of the active connecting rod 20 under the action of gravity, so that the entire active connecting rod 20 has an upward tendency, thereby causing the first rotating shaft 11 of the crank to continue to slide along the set lower arc segment. The rotational angular velocity obtained during the movement of the air guide plate 50 in the driving mechanism provided by the embodiment of the present disclosure with the electromagnetic element 44 is as follows: Figure 14 It can be seen that in the driving mechanism provided by the embodiment of the present disclosure, the provision of electromagnetic elements improves the uniformity of the rotational angular velocity formed during the rotation of the air guide plate 50, thereby improving the motion stability of the air guide plate 50.

[0084] Optionally, the driving mechanism provided by the embodiment of the present disclosure further includes a track plate 40. The track plate 40 is provided with a herringbone track, which includes a straight section and an upper branch section 41 and a lower branch section 42 separated from the straight section, wherein the electromagnetic element is provided at the intersection of the upper branch section 41 and the lower branch section 42, as shown in FIG. Figure 8 shown.

[0085] like Figure 4As shown, the active connecting rod 20 is provided with a first limiting slider 25 that moves along the herringbone track. When the first limit slider 25 of the active connecting rod 20 slides along the straight section of the herringbone track, the air guide plate 50 extends out in a straight line driven by the active connecting rod 20 and the driven connecting rod 30. When the first limit slider 25 slides along the lower branch section 42 of the herringbone track, the first rotating shaft 11 of the crank slides along the first upper arc section 21. When the first rotating shaft 11 of the crank slides to the connection point of the first upper arc section 21 and the first lower arc section 22, the control electromagnetic element 44 is energized, so that the first rotating shaft 11 continues to slide along the first lower arc section 22, and the air guide plate 50 opens upward; when the first limit slider 25 slides along the upper branch section 41 of the herringbone track, the first rotating shaft 11 of the crank slides along the second upper arc section 23. When the first rotating shaft 11 of the crank slides to the connection point of the second upper arc section 23 and the second lower arc section 24, the control electromagnetic element is energized, so that the first rotating shaft 11 continues to slide along the second lower arc section 24, and the air guide plate 50 opens downward.

[0086] like Figure 8 As shown, in the driving mechanism provided by the embodiment of the present disclosure, the electromagnetic element 44 is arranged at the intersection of the upper branch section 41 and the lower branch section 42 of the herringbone track. It can not only attract the active connecting rod 20 sliding along the first upper arc section 21, so that the first rotating shaft 11 of the crank continues to slide along the first lower arc section 22, thereby improving the uniformity of the rotational angular velocity when the air guide plate 50 opens upward, but also attract the active connecting rod 20 sliding along the second upper arc section 23, so that the first rotating shaft 11 of the crank continues to slide along the second lower arc section 24, thereby improving the uniformity of the rotational angular velocity when the air guide plate 50 opens downward.

[0087] Optionally, the track plate includes a first plate surface provided with a herringbone track and a second plate surface opposite to the first plate surface, wherein the electromagnetic element is provided on the first plate surface, or the electromagnetic element is provided on the second plate surface, or the electromagnetic element is embedded in the track plate.

[0088] Alternatively, the electromagnetic element 44 can be located on the same first plate surface as the herringbone track. This helps enhance the electromagnetic element 44's attraction to the attraction element. Alternatively, the electromagnetic element 44 can be located on the second plate surface. This way, the electromagnetic element 44 avoids the movement of the active connecting rod 20, facilitating the sliding of the active connecting rod 20 along the herringbone track on the track plate 40. Alternatively, the electromagnetic element 44 can be embedded within the track plate 40.

[0089] Optionally, the electromagnetic element 44 includes an electromagnet. The first limit slider 25 includes an iron sliding core, which is an attraction element.

[0090] When energized, the electromagnet attracts the iron sliding core in the first limit slider 25 , causing the first limit slider 25 of the active connecting rod 20 to slide along the upper branch section 41 of the herringbone track, thereby opening the air guide plate 50 downward.

[0091] Optionally, the first limiting slider 25 further includes a sliding sleeve sleeved on the outside of the iron sliding core. The setting of the sliding sleeve is conducive to the first limiting slider 25 sliding smoothly along the herringbone track.

[0092] The track plate 40 is provided with a herringbone track, which includes a straight section and an upper branch section 41 and a lower branch section 42 branching from the straight section. The active connecting rod 20 is provided with a first limiting slider 25 that slides along the herringbone track. The first limiting slider 25 slides along the upper branch section 41 to open the air deflector 50 downward; the first limiting slider 25 slides along the lower branch section 42 to open the air deflector 50 upward.

[0093] The track plate 40 is provided with a track capable of limiting the movement of the active link 20 and the driven link 30. The track includes a herringbone track that limits the movement of the active link 20, such as Figure 8 As shown. The herringbone track includes a straight section extending along the direction in which the air deflector 50 extends, as well as an upper branch section 41 and a lower branch section 42. Driven by the rotating shaft 11 of the crank 10, when the first limiting slider 25 of the active connecting rod 20 slides along the straight section, the air deflector 50 extends to a first preset position. When the first limiting slider 25 slides along the upper branch section 41, the air deflector 50 extends and rotates at the first preset position, causing the air deflector 50 to open downward. When the first limiting slider 25 slides along the lower branch section 42, the air deflector 50 extends and rotates at the first preset position, causing the air deflector 50 to open upward.

[0094] Optionally, the track plate 40 further includes a linear track 43 provided at the lower portion of the herringbone track. The active link 20 further includes a second limiting slider 26 sliding along the linear track 43. The first limiting slider 25 and the second limiting slider 26 together limit the movement of the active link 20.

[0095] Optionally, the driven connecting rod 30 is provided with a through slot passing through the driven connecting rod 30 , and the second limiting slider 26 of the active connecting rod 20 can pass through the through slot and slide along the linear track 43 of the track plate 40 .

[0096] Optionally, the driven connecting rod 30 is provided with a third limiting sliding block sliding along the linear track 43 .

[0097] The number of the third limit sliders can be multiple, and the multiple third limit sliders are not on the same straight line. For example, if there are 3 third limit sliders, Figure 7As shown, the track plate 40 includes a third limiting slider 1'31, a third limiting slider 2'32, and a third limiting slider 3'33. Correspondingly, the track plate 40 is provided with three linear tracks extending along the direction in which the air deflector 50 extends. The three third limiting sliders slide along the three linear tracks on the track plate 40, respectively. This can more stably limit the linear motion of the driven connecting rod 30. Optionally, the three third limiting sliders are arranged in a triangular shape. This improves the track plate 40's ability to limit the motion trajectory of the driven connecting rod 30.

[0098] The driving mechanism for the air deflector 50 provided in the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

[0099] The initial state of the driving mechanism when the air guide plate 50 is in the closed state is as follows: Figure 1 As shown. When the crank 10 is Figure 1 When the initial position shown rotates in the first direction or the second direction, the first rotating shaft 11 slides in the sliding groove of the active connecting rod 20 to drive the active connecting rod 20 and the driven connecting rod 30 to move. Specifically, the active connecting rod 20 moves linearly along the straight section of the herringbone track on the track plate, and the driven connecting rod 30 moves linearly along the linear track on the track plate, thereby driving the air deflector 50 to move linearly 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 limit slider 25 of the active connecting rod 20 moves to the end of the straight section. In the disclosed embodiment, the first direction is clockwise, and the second direction is counterclockwise.

[0100] When the crank 10 rotates in the first direction and the air guide plate 50 reaches the first preset position, the second rotation axis 26 of the crank 10 moves to the first limit point A. Figure 6 As shown, due to the contact force between the second rotating shaft 26 and the first limit point A, the first limit slider 25 of the active link 20 provides the driving force to select the track, so that the first limit slider 25 of the active link 20 enters the lower branch section 42 from the straight section of the herringbone track, and the second limit slider 26 of the active link 20 passes through the through slot of the driven link 30 and continues to move within the linear track 43, causing the active link 20 to change direction. At the same time, the driven link 30 continues to move linearly along the linear track 43. In this way, the wind deflector 50 is opened upward under the joint drive of the active link 20 and the driven link 30, as shown in FIG. Figure 10 shown.

[0101] When the crank 10 rotates in the second direction, when the air guide plate 50 reaches the first preset position, the second rotation axis 13 of the crank 10 moves to the second limit point B, as shown in FIG. Figure 6As shown, due to the contact force between the second rotating shaft 13 and the second limiting point B, the first limiting slider 25 of the active link 20 provides the driving force to select the track, so that the first limiting slider 25 of the active link 20 enters the upper branch section 41 from the straight section of the herringbone track, and the second limiting slider 26 of the active link 20 passes through the through slot of the driven link 30 and continues to move within the linear track 43, causing the active link 20 to change direction. At the same time, the driven link 30 continues to move linearly along the linear track 43. In this way, the wind deflector 50 is opened downward under the joint drive of the active link 20 and the driven link 30, as shown in FIG. Figure 11 shown.
