Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example to a drive mechanism for an air guide vane and an air conditioner. Background Technology

[0002] An air deflector is a component used to guide airflow from the air outlet of an air conditioner's indoor unit. Currently, to avoid interference between the air deflector and the unit casing during rotation, the air deflector drive mechanism generally adopts a push-out type. This means the air deflector drive mechanism has a pushing component that pushes the air deflector away from the air outlet, thus preventing interference and allowing the air deflector to rotate at a large angle. Furthermore, when the air deflector retracts, it achieves a complete seal of the air outlet, improving the aesthetics of the air conditioner's indoor unit.

[0003] In existing air guide plate drive mechanisms, a first pushing component and a second pushing component are provided, such that the first pushing component is hinged to the rotation center of the air guide plate, and a first driving device drives the first pushing component to complete the extension and retraction movement of the air guide plate; and the second pushing component is hinged to the non-rotation center of the air guide plate, such that when the first pushing component and the second pushing component move relative to each other, the relative positional relationship between the rotation center and the non-rotation center of the air guide plate changes, causing the air guide plate to rotate and completing the sweeping operation.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The existing drive mechanism for extending and rotating the air guide plate is complex, and the uniformity of the air guide plate during rotation is poor, which affects the stability of the air guide plate's movement. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a driving mechanism for an air guide plate. By setting electromagnetic components, the first rotating shaft of the crank smoothly enters the first lower arc section after sliding along the first upper arc section, thereby improving the uniformity of the rotational angular velocity during the rotation of the air guide plate and thus improving the stability of the air guide plate rotation process.

[0008] In some embodiments, the driving mechanism of the air guide plate includes: a crank, including a first rotating shaft; an active connecting rod, one end of which is rotatably connected to the air guide plate, the active connecting rod being provided with a curved groove for sliding the first rotating shaft, so that the active connecting rod moves under the drive of the crank, the curved groove including a first curved segment, the first curved segment including a first upper arc segment and a first lower arc segment that are bent and connected; a driven connecting rod, one end of which is rotatably connected to the air guide plate, the driven connecting rod moving under the drive of the active connecting rod, the active connecting rod and the driven connecting rod driving the air guide plate to extend and close the air outlet of the indoor unit of the air conditioner; and an electromagnetic element, wherein the active connecting rod is provided with an attraction element that can be attracted by the electromagnetic element, the electromagnetic element being used to attract the attraction element in an energized state, so that the first rotating shaft slides along the first lower arc segment of the curved groove.

[0009] Optionally, the curved groove further includes a second curved segment, which is symmetrically arranged with respect to the first curved segment, wherein the first curved segment and the second curved segment are connected.

[0010] Optionally, the curved groove is butterfly-shaped.

[0011] Optionally, the drive mechanism further includes: a track plate with a herringbone track, the herringbone track including a straight section and an upper branch section and a lower branch section branching from the straight section, wherein the electromagnetic element is disposed at the intersection of the upper branch section and the lower branch section.

[0012] Optionally, the track slab includes a first plate surface on which the herringbone track is provided, and a second plate surface opposite to the first plate surface, wherein the electromagnetic element is disposed on the first plate surface; or, the electromagnetic element is disposed on the second plate surface; or, the electromagnetic element is embedded in the track slab.

[0013] Optionally, the electromagnetic element includes an electromagnet.

[0014] Optionally, the active linkage includes a first limiting slider that slides along the herringbone track of the track plate, wherein the attraction element is part or all of the first limiting slider.

[0015] Optionally, the first limiting slider includes an iron sliding core, which is the attraction element.

[0016] Optionally, the track plate is further provided with a linear track, the driving link is provided with a second limiting slider that slides along the linear track, and the driven link is provided with a third limiting slider that slides along the linear track.

[0017] In some embodiments, the air conditioner includes a drive mechanism for the air guide vane as described above.

[0018] The drive mechanism for the air guide vane and the air conditioner provided in the disclosed embodiments can achieve the following technical effects:

[0019] The driving mechanism provided in this embodiment includes an electromagnetic element, and the active connecting rod is equipped with an attraction element that can be attracted by the electromagnetic element. When the electromagnetic element is energized, the electromagnetic element attracts the attraction element, overcoming the downward tendency of the active connecting rod under gravity, and pulling the active connecting rod to generate an upward tendency. This allows the crank to smoothly slide through the bend and connect to the first lower arc segment after sliding along the first upper arc segment of the first curve segment, thus improving the uniformity of the rotational angular velocity during the extension of the air guide plate, and further improving the stability of the air guide plate during rotation.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0050] This disclosure provides an air conditioner.

[0051] This air conditioner is a large guide plate type. When the air guide plate 50 is closed, it can completely seal the air outlet, and there is no gap between the air guide plate 50 and the air outlet. Furthermore, during airflow, the air guide plate 50 extends out of the air conditioner before rotating to guide the air. This distance between the air guide plate 50 and the air outlet reduces air resistance, thus minimizing noise generated at the air guide plate 50 during airflow. Simultaneously, compared to rotating the air guide plate 50 at the air outlet, rotating it outside the air outlet allows for a wider angle and greater range of airflow, improving the cooling or heating effect of the air conditioner. Optionally, the air conditioner provided in this embodiment can also be a cabinet unit or a ducted unit, etc.

[0052] In some embodiments, the air conditioner includes a drive mechanism for extending and rotating the air deflector.

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

[0054] This disclosure also provides a drive mechanism for extending and rotating the air guide plate 50, such as... Figures 1 to 14 As shown.

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

[0056] The driving mechanism provided in this embodiment includes a crank 10, a driving connecting rod 20, and a driven connecting rod 30. The crank 10 can rotate under the drive of a stepper motor. The first rotating shaft 11 of the crank 10 slides along the groove of the driving connecting rod 20, thereby driving the driving connecting rod 20 to move. The driving connecting rod 20 then drives the driven connecting rod 30 to move. The driving mechanism provided in this embodiment can simultaneously drive the air guide plate 50 to extend and rotate, simplifying the structure of the air guide plate 50 driving mechanism.

[0057] Optionally, the groove is curved.

[0058] Figure 5A linear slide groove 27 is shown. The first rotating shaft 11 of the crank rotates along its rotation center 12, producing a circular motion trajectory. When the first rotating shaft 11, making circular motion, slides within the linear slide groove 27, it generates a pushing force on the driving connecting rod 20. However, under the action of this pushing force, the extension speed of the guide vane 50 driven by the driving connecting rod 20 and the driven connecting rod 30 is as follows... Figure 12 As shown. From Figure 12 As can be seen, 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 extend the air guide plate 50 gradually changes, resulting in poor uniformity and thus affecting the stability of the air guide plate 50 extension.

[0059] The slide groove provided in this embodiment is a curved slide groove, which allows the first rotating shaft 11 of the crank to move along the curved slide groove. This improves the uniformity of the linear thrust generated by the movement of the first rotating shaft 11, allowing the active connecting rod 20 and the driven connecting rod 30 to drive the guide plate 50 to extend at a relatively uniform speed, thus improving the stability of the guide plate 50 during its extension process. It is understood that the drive mechanism provided in this embodiment can simultaneously drive the guide plate 50 to extend and rotate. During this "rotation," the guide plate 50 is still extended; that is, the rotation here can be understood as "extending and rotating simultaneously." The curved slide groove provided in this embodiment improves the uniformity of the extension speed of the guide plate 50. Here, "extension speed" includes the extension speed when the guide plate 50 extends in a straight line, as well as the extension speed during rotation. The curved slide groove provided in this embodiment improves the uniformity of the "extension speed" throughout the entire movement of the guide plate 50, thereby improving the stability of the entire movement process of the guide plate 50. Optionally, the direction of the thrust generated by the first rotating shaft of the crank is the same as the direction when the air guide plate extends in a straight line. Similarly, reversing the first rotating shaft of the crank can cause the air guide plate to retract to the air outlet.

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

[0061] Optionally, the curved chute can be an elliptical chute. For example, it can be a chute formed by connecting two semi-ellipses. Optionally, the arc lengths of the two semi-ellipses are not equal. This further improves the uniformity of the driving force generated by the first rotating shaft 11 and enhances the stability of the air guide plate 50 during its extension process.

[0062] Optionally, the curved groove includes a first curved segment, which includes a first upper arc segment 21 and a first lower arc segment 22. The first lower arc segment 22 is bent and connected to the first upper arc segment 21, and the first lower arc segment 22 is located at the lower part of the corresponding position of the first upper arc segment 21.

[0063] like Figure 3 As shown, the first curved segment is composed of an interconnected upper arc segment 21 and a lower arc segment 22. Optionally, the bending directions of the first upper arc segment 21 and the first lower arc segment 22 are opposite, further improving the uniformity of the extension speed of the air guide plate 50. Figure 3 As shown, the first upper arc segment bends downwards, and the first lower arc segment bends upwards.

[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 lengths of the two arc segments are not equal, and the arc length of the first upper arc segment 21 is greater than that 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 driving connecting rod 20 and the driven connecting rod 30 drive the air guide plate 50 to extend linearly. At the same time, the first rotating shaft 11 continues to move along the first upper arc segment 21, and the driving connecting rod 20 and the driven connecting rod 30 can drive the air guide plate 50 to rotate. When the first rotating shaft 11 of the crank moves to the first lower arc segment 22, the driving connecting rod 20 and the driven connecting rod 30 drive the air guide plate 50 to continue rotating until the air guide plate 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] Both the first upper arc segment 21 and the first lower arc segment 22 are 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, as shown below. 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 guide vane 50 during its extension process. Optionally, the first upper arc segment 21 includes a first end point connected to the second upper arc segment 23 and a second end point connected to the first lower arc segment 22. The linear distance between the first end point and the second end point 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 from the first upper arc segment 21 to the first lower arc segment 22.

[0068] Optionally, the curved groove further includes a second curved segment symmetrical to the first curved segment. The second curved segment includes a second upper arc segment 23 and a second lower arc segment 24. The second lower arc segment 24 is bent and connected to the second upper arc segment 23, and is located below the corresponding position of the second upper arc segment 23. The first upper arc segment 21 is connected to the second upper arc 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 lengths of the two arc segments are not equal, and the arc length of the second upper arc segment 23 is greater than that 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 driving connecting rod 20 and the driven connecting rod 30 drive the air guide plate 50 to extend linearly. At the same time, the first rotating shaft 11 continues to move along the second upper arc segment 23, and the driving connecting rod 20 and the driven connecting rod 30 can drive the air guide plate 50 to rotate. When the first rotating shaft 11 of the crank moves to the second lower arc segment 24, the driving connecting rod 20 and the driven connecting rod 30 drive the air guide plate 50 to continue to rotate until the air guide plate 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] Both the second upper arc segment 23 and the second lower arc segment 24 are 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, such as... 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 guide vane 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 from the second upper arc segment 23 to the second lower arc segment 24.

[0073] Optionally, the arc length and radii of the first upper arc segment 21 and the second upper arc segment 23 are equal, and the arc length and radii of the first lower arc segment 22 and the second lower arc segment 24 are equal. The curved slide includes a first curved segment and a second curved segment that are symmetrically arranged and interconnected, and can also be called a hyperbolic slide. 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 slide is butterfly-shaped, such as... Figure 3As shown.

[0074] The first rotating shaft 11 of the crank is along as follows Figure 3 When the butterfly-shaped slide groove shown slides, the extension speed of the guide vane 50 driven by the active link 20 and the driven link 30 during the movement is as follows: Figure 13 As shown. From Figure 13 As can be seen, the extension speed of the air guide plate 50 is relatively uniform throughout its entire movement. Compared to the straight groove 27, the butterfly-shaped groove provided in this embodiment greatly improves the uniformity of the extension speed of the air guide plate 50 throughout its entire movement, thereby improving the stability of the air guide plate 50 during its extension process.

[0075] Optionally, the shape of the chute is obtained by fitting the 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 slide is restricted to a straight line, the uniformity of the extension speed of the guide plate 50 during the entire movement process caused by the pushing force obtained by the first rotating shaft 11 of the crank sliding in the straight slide 27 is poor, which affects the stability of the movement process of the guide plate 50. In this embodiment, the shape of the slide 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 guide plate 50. This makes the shape of the slide and its setting position on the active connecting rod 20 more in line with the requirements for uniform speed, extension distance, rotation angle, etc. during the extension and rotation of the guide plate 50, thereby improving the stability and controllability of the entire movement process of the guide plate 50.

[0077] Optionally, the shape of the chute 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 chute.

[0078] Based on the constraint that the guide vane 50 extends and rotates at a constant speed, the motion trajectory formed by the first rotating shaft on the active connecting rod 20 is used as the shape of the groove, which further improves the precision of the shape constraint of the groove, thereby improving the uniformity and stability of the guide vane 50 throughout the entire motion process. It can be understood that "uniform rotation" here refers to the uniformity of the linear extension speed included in the extension and rotation process.

[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 the chute. This includes: controlling the air guide plate 50 to extend 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 part of the shape of the chute; and controlling the air guide plate 50 to extend and open downward at a uniform speed, and the motion trajectory formed by the first rotating shaft 11 on the active connecting rod 20 is another part of the shape of the chute.

[0080] When the air guide plate 50 extends and opens upwards at a uniform speed, the motion trajectory formed by the first rotating shaft 11 on the active connecting rod 20 is part of the shape of the chute; when the motor is reversed, and the air guide plate 50 extends and opens downwards at a uniform speed, the motion trajectory formed by the first rotating shaft on the active connecting rod 20 is another part of the shape of the chute. The shape of the chute provided in this embodiment improves both the uniformity and stability of the entire motion process when the air guide plate 50 opens upwards and downwards.

[0081] Optionally, the fitted groove can be butterfly-shaped, such as... Figure 3 As shown, after the first rotating shaft 11 of the crank slides in the butterfly-shaped groove, the extension speed of the guide vane 50 during the entire movement process is as follows: Figure 13 As shown, the shape of the groove obtained by fitting, as provided in this embodiment, 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 groove for sliding the first rotating shaft 11 of the crank. The curved groove includes a first upper arc segment and a first lower arc segment that are bent and connected. The air guide plate 50 motion 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 used to attract the attraction element when energized, so that the first rotating shaft slides along the lower arc segment of the curved groove.

[0083] In the initial state, the first rotation axis 11 of the crank is located at the first end of the upper arc segment, as shown below. Figure 1As shown, the first rotating shaft 11 of the crank slides along the upper arc segment, causing the air guide plate 50 to extend linearly to the first preset position, and then continues to drive the air guide plate 50 to rotate. When the first rotating shaft 11 rotates to the connection between the upper and lower arc segments, due to the gravity of the active connecting rod 20, the active connecting rod 20 tends to sink. At this time, the first rotating shaft 11 tends to continue to slide preferentially along the upper arc segment instead of sliding along the lower arc segment as set. This affects the uniformity and stability of the rotation process of the air guide plate 50, and may even cause the air guide plate 50 to jam during rotation, affecting the normal movement of the air guide plate 50. In the drive mechanism provided in this embodiment, an electromagnetic element 44 is provided. When the first rotating shaft 11 of the crank slides to the connection between the first upper arc segment and the first lower arc segment, the electromagnetic element 44 is energized to attract the attraction element provided on the active connecting rod 20. The attraction effect of the electromagnetic element 44 overcomes the downward tendency of the active connecting rod 20 under the action of gravity, causing the entire active connecting rod 20 to have an upward tendency, thereby causing the first rotating shaft 11 of the crank to continue sliding along the set lower arc segment. The rotational angular velocity obtained by the air guide plate 50 during the movement of the drive mechanism provided in this embodiment is as follows: Figure 14 As shown, the drive mechanism provided in this embodiment improves the uniformity of the rotational angular velocity generated during the rotation of the air guide plate 50 by setting electromagnetic components, thereby improving the motion stability of the air guide plate 50.

[0084] Optionally, the driving mechanism provided in this embodiment further includes a track plate 40. The track plate 40 is provided with a herringbone track, which includes a straight segment and an upper branch segment 41 and a lower branch segment 42 branching off from the straight segment. An electromagnetic element is disposed at the intersection of the upper branch segment 41 and the lower branch segment 42, such as... Figure 8 As shown.

[0085] like Figure 4As shown, the active linkage 20 is equipped with a first limiting slider 25 that moves along a herringbone track. When the first limiting slider 25 of the active connecting rod 20 slides along the straight section of the herringbone track, the air guide plate 50 extends linearly under the drive of the active connecting rod 20 and the driven connecting rod 30. When the first limiting 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 limiting 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 in this embodiment, the electromagnetic element 44 is disposed at the intersection of the upper branch segment 41 and the lower branch segment 42 of the herringbone track. It can attract the active connecting rod 20 that slides along the first upper arc segment 21, so that the first rotating shaft 11 of the crank continues to slide along the first lower arc segment 22, thereby improving the uniformity of the rotational angular velocity of the air guide plate 50 when it opens upward. It can also attract the active connecting rod 20 that slides along the second upper arc segment 23, so that the first rotating shaft 11 of the crank continues to slide along the second lower arc segment 24, thereby improving the uniformity of the rotational angular velocity of the air guide plate 50 when it opens downward.

[0087] Optionally, the track slab includes a first surface with a herringbone track and a second surface opposite to the first surface. The electromagnetic element is disposed on the first surface, or on the second surface, or embedded within the track slab.

[0088] Optionally, the electromagnetic element 44 can be disposed on the first plate surface, which is the same as the plate surface where the herringbone track is located. This is beneficial to improving the attraction effect of the electromagnetic element 44 on the attraction element. Optionally, the electromagnetic element 44 can be disposed on the second plate surface. This allows the electromagnetic element 44 to avoid the movement of the active connecting rod 20, which is beneficial to the sliding of the active connecting rod 20 along the herringbone track on the track plate 40. Optionally, the electromagnetic element 44 can also be embedded inside the track plate 40.

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

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

[0091] Optionally, the first limiting slider 25 may also include a sliding sleeve fitted over the outside of the iron sliding core. The sliding sleeve facilitates the smooth sliding of the first limiting slider 25 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 off from the straight section. The active linkage 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, causing the air guide plate 50 to open downward; the first limiting slider 25 slides along the lower branch section 42, causing the air guide plate 50 to open upward.

[0093] The track plate 40 is provided with a track capable of limiting the movement of the driving link 20 and the driven link 30. The track includes a herringbone track that limits the movement of the driving link 20, such as... Figure 8 As shown. The herringbone track includes a straight section extending along the extension direction of the air guide plate 50, as well as an upper branch section 41 and a lower branch section 42. Driven by the rotation 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 guide plate 50 extends to a first preset position. When the first limiting slider 25 slides along the upper branch section 41, the air guide plate 50 extends and rotates at the first preset position, causing the air guide plate 50 to open downwards. When the first limiting slider 25 slides along the lower branch section 42, the air guide plate 50 extends and rotates at the first preset position, causing the air guide plate 50 to open upwards.

[0094] Optionally, the track plate 40 also includes a straight track 43 disposed below the herringbone track. The drive link 20 also includes a second limiting slider 26 that slides along the straight track 43. The first limiting slider 25 and the second limiting slider 26 together limit the movement of the drive link 20.

[0095] Optionally, the driven link 30 is provided with a through groove, through which the second limiting slider 26 of the driving link 20 can pass through the through groove and slide along the linear track 43 of the track plate 40.

[0096] Optionally, the driven link 30 is provided with a third limiting slider that slides along the linear track 43.

[0097] There can be multiple third limit sliders, and these multiple third limit sliders are not on the same straight line. For example, there can be 3 third limit sliders, such as... Figure 7As shown, it includes third limiting sliders 1'31, 2'32, and 3'33. Correspondingly, the track plate 40 is provided with three straight tracks extending along the extension direction of the guide plate 50. The three third limiting sliders slide along the three straight tracks on the track plate 40, thus more stably limiting the linear motion of the driven link 30. Optionally, the three third limiting sliders are arranged in a triangle. This improves the limiting effect of the track plate 40 on the motion trajectory of the driven link 30.

[0098] The driving mechanism for the air guide plate 50 provided in this embodiment drives the air guide plate 50 to move in the following way:

[0099] The initial state of the drive mechanism when the air guide plate 50 is closed is as follows: Figure 1 As shown. When crank 10 from Figure 1 When the initial position shown is rotated along the first or second direction, the first rotating shaft 11 slides within the 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 segment of the herringbone track on the track plate, and the driven connecting rod 30 moves linearly along the straight track on the track plate, thereby driving the air guide plate 50 to move linearly to the first preset position. The first preset position can be understood as the position of the air guide plate 50 corresponding to the end of the straight segment when the first limiting slider 25 of the active connecting rod 20 moves. In this 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 shaft 26 of the crank 10 moves to the first limit point A, as shown. Figure 6 As shown, due to the contact force between the second rotating shaft 26 and the first limiting point A, the first limiting slider 25 of the active connecting rod 20 is provided with the driving force to select the track, causing the first limiting slider 25 of the active connecting rod 20 to enter the lower branch section 42 from the straight section of the herringbone track. The second limiting slider 26 of the active connecting rod 20 passes through the through slot of the driven connecting rod 30 and continues to move in the straight track 43, causing the active connecting rod 20 to change direction. At the same time, the driven connecting rod 30 continues to move linearly along the straight track 43. Thus, the air guide plate 50 opens upward under the combined drive of the active connecting rod 20 and the driven connecting rod 30. Figure 10 As shown.

[0101] When crank 10 rotates in the second direction, and the air guide plate 50 reaches the first preset position, the second rotation shaft 13 of crank 10 moves to the second limit point B, as shown. 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 is provided with the driving force to select the track, causing the first limiting slider 25 of the active link 20 to enter the upper branch section 41 from the straight section of the herringbone track. The second limiting slider 26 of the active link 20 passes through the through slot of the driven link 30 and continues to move in the straight track 43, causing the active link 20 to change direction. At the same time, the driven link 30 continues to move linearly along the straight track 43. Thus, the guide vane 50 opens downward under the combined action of the active link 20 and the driven link 30. Figure 11 As shown.
