Detailed Implementation
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.
[0026] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.
[0027] Please see Figure 1This application provides an air outlet device 200 for discharging air. This specification does not limit the specific type of the air outlet device 200; for example, the air outlet device 200 can be a household appliance such as an air conditioner, heater, or fan.
[0028] The air outlet device 200 may include an air outlet body 201 and an opening / closing mechanism 100. The air outlet body 201 has an air outlet 2012, and the opening / closing mechanism 100 is disposed within the air outlet body 201. The air outlet body 201 may be an air conditioner body, a heater body, a fan body, etc., and may also contain structures such as a fan, a cooling mechanism, and a control mechanism, wherein the air outlet side of the fan is connected to the air outlet 2012. This specification does not limit the specific shape of the air outlet 2012; for example, the air outlet 2012 may be an annular air outlet, a rectangular air outlet, or other irregularly shaped air outlets. The opening / closing mechanism 100 is disposed within the air outlet body 201 and has a movable hinge 12. When the air outlet device 200 is not discharging air, the hinge 12 can move to the air outlet 2012 to close the air outlet 2012; when the air outlet device 200 is discharging air, the hinge 12 can move to connect the air outlet 2012 with the outside, thereby facilitating the discharging of air from the air outlet device 200.
[0029] Please also refer to Figure 2 and Figure 3 In this embodiment, the opening and closing mechanism 100 may include an opening and closing unit 10, a guide rail 30, and a drive assembly 50. At least two sets of opening and closing units 10 are provided, arranged circumferentially along the guide rail 30. Each opening and closing unit 10 may include a hinge 12, a first support 14, and a second support 16. The first support 14 and the second support 16 are connected to the hinge 12 and spaced apart circumferentially along the guide rail, that is, spaced apart along the arrangement direction of adjacent hinges 12. The guide rail 30 is provided with a track 32 for defining the movement direction of the hinge 12, and the first support 14 and the second support 16 are slidably connected to the track 32. The drive assembly 50 is connected to the first support member 14 and the second support member 16. The drive assembly 50 drives the first support member 14 to move the hinge 12, causing the hinge 12 to switch between a first position and a second position. The drive assembly 50 drives the second support member 16 to move in a direction perpendicular to the plane of the guide rail 30, causing the hinge 12 to flip, so that the two ends of the hinge 12 are in an inclined state. The guide rail 30 has a preset center A, and the first position corresponding to each hinge 12 is located between its second position and the preset center A. Each hinge 12 can switch from the second position to the first position. When the drive assembly 50 drives the hinge 12 to flip so that when the hinge 12 is in the first position, at least part of the structure of two adjacent hinges 12 overlaps each other.
[0030] When the opening and closing mechanism 100 is in use, with the hinge 12 in the second position, at least two hinges 12 are arranged sequentially around the outer periphery of the preset center A, at which point at least two hinges 12 close the air outlet 2012. When the air outlet device 200 needs to discharge air, the drive component 50 drives at least two hinges 12 to move synchronously along the track 32, moving from their respective second positions to their respective first positions. At this time, the hinges 12 no longer close the air outlet 2012, and the air outlet 2012 is connected to the outside, allowing the air outlet device 200 to discharge air through the air outlet 2012. When each hinge 12 is in its corresponding first position, at least a portion of the structure of two adjacent hinges 12 overlaps each other to avoid interference when the hinges 12 make way for the air outlet. The opening and closing mechanism 100 provided in this application synchronously controls the translation and rotation of the hinges 12 through a drive component 50, resulting in a simple structure and low manufacturing cost.
[0031] When applied to the air outlet device 200, the guide rail 30 is provided with multiple tracks 32, such as at least two tracks 32. These at least two tracks 32 are corresponding one-to-one with multiple opening and closing units 10. At least two opening and closing flaps 12, driven by the drive assembly 50, can move synchronously along their corresponding tracks 32 to switch between their respective first and second positions. The aforementioned first position is understood to mean that the opening and closing flap 12 does not obstruct the air outlet 2012 (e.g., ...). Figure 1 As shown in the figure, the air outlet 2012 is connected to the outside. The second position mentioned above is understood as the position where the hinge 12 is located at the air outlet 2012 and closes the air outlet 2012.
[0032] The opening and closing mechanism 100 provided in this application synchronously drives at least two opening and closing flaps 12 to move along the corresponding tracks 32, so as to achieve simultaneous opening and closing and reduce the phenomenon of action delay or displacement deviation of the opening and closing flaps 12; the air outlet 2012 opens and closes continuously, improving the user experience and reducing the possibility of problems such as vortex noise caused by discontinuous airflow channels.
[0033] The hinges 12 can move and flip synchronously under the drive of the drive component 50, so that multiple hinges 12 can overlap each other when in the first position to avoid interference. In this embodiment, the first position corresponding to each hinge 12 is located between its second position and the preset center A. The hinge 12 moves from the second position to the first position by retracting inward from the air outlet 2012 to expose the air outlet 2012. In other embodiments, the second position corresponding to each hinge 12 may be located between its first position and the preset center A, and the first position is located on the outer ring. That is, multiple hinges 12 move from the second position to the first position by moving outward from the air outlet 2012 to expose the air outlet 2012.
[0034] In this application, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0035] In some embodiments, the number of opening and closing units 10 is provided in at least three sets. When each opening and closing flap 12 is in its corresponding second position, at least three opening and closing flaps 12 are arranged around the outer periphery of a preset center A, and sequentially connected end-to-end to form a ring-shaped closed structure. The surfaces of the at least three opening and closing flaps 12 on the same side are flush. The center of the aforementioned ring-shaped closed structure is collinear with the preset center A. In the second position, at least three opening and closing flaps 12 form a ring-shaped closed structure, which can effectively seal the air outlet 2012 (e.g., ...). Figure 1 As shown, this prevents foreign objects from entering the air outlet body 201 through the air outlet 2012 when the air outlet device 200 is not in use. When the above-mentioned ring-shaped closed structure is formed, the flush side of the hinge 12 can be used as the side surface of the hinge 12 facing the outside, so as to improve the flatness and aesthetics of the appearance of the air outlet device 200 when the air outlet 2012 is closed.
[0036] When at least three hinges 12 are in the second position, the resulting annular closed structure must be able to cover the air outlet 2012. This specification does not limit the specific shape of the hinges 12; they can be rectangular blades, curved blades, or fan-shaped blades. As an example, the air outlet 2012 is an annular air outlet, and the hinges 12 are curved blades, each hinge 12 being a part of an arc. When the hinges 12 are in the corresponding second position, all the hinges 12 are joined together to form a complete annular shape, thus seamlessly covering the annular air outlet 2012. As another example, the air outlet 2012 is a square annular air outlet, and the hinges 12 are trapezoidal or parallelogram-shaped blades. When the hinges 12 are in the corresponding second position, all the hinges 12 are joined together to form a complete square annular shape.
[0037] In this embodiment, the air outlet 2012 is a circular air outlet, and the hinge 12 is roughly in the shape of an arc blade. There are at least three hinges 12; this specification does not limit the specific number of hinges 12, for example, the number of hinges 12 can be three, four, five, six, etc. In this embodiment, the number of opening and closing units 10 is set to four, so the number of hinges 12 is four. When each hinge 12 is in its corresponding second position, the four hinges 12 are arranged around the periphery of the preset center A, and sequentially connected end-to-end to form a closed annular structure. When the four hinges 12 are in their corresponding first positions, at least part of the structure of two adjacent hinges 12 overlaps each other, achieving synchronous switching of the hinges 12 positions while avoiding interference between them.
[0038] To improve the flatness of the hinge 12 in the second position, forming a ring-shaped closed structure, in this embodiment, the first support member 14 includes a rotation axis, and the hinge 12 can be flipped about this rotation axis. The hinge 12 may include a stacked portion 121 and a clearance portion 123 connected to each other, bounded by the rotation axis. When each hinge 12 is in the corresponding second position, the stacked portion 121 and the clearance portion 123 are arranged sequentially along the circumference of a predetermined center A. In the first position, the stacked portion 121 is stacked with the clearance portion 123 of the adjacent hinge 12, and the stacked portion 121 is located on the side of the clearance portion 123 where the first support member 14 is located.
[0039] The overlapping portion 121 and the clearance portion 123 are smoothly connected along the extension arc of the hinge 12. In the second position, along the circumference around the predetermined center A, the side of the overlapping portion 121 of one hinge 12 that faces away from the clearance portion 123 of that hinge 12 is in contact with the clearance portion 123 of the adjacent hinge 12. As an example, if the four hinges 12 respectively include a first hinge, a second hinge, a third hinge, and a fourth hinge, in the second position, the first hinge, the second hinge, the third hinge, and the fourth hinge are connected end to end. Among them, the overlapping portion 121 of the first hinge is in contact with the clearance portion 123 of the fourth hinge, and the clearance portion 123 of the first hinge is in contact with the overlapping portion 121 of the second hinge. In the first position, the overlapping portion 121 of the first hinge is placed below the clearance portion 123 of the fourth hinge, and the clearance portion 123 of the first hinge is placed above the overlapping portion 121 of the second hinge. The four hinges 12 switch from their corresponding second positions to the first positions, and the four hinges 12 fold towards the preset center A, overlapping each other to expose the air outlet 2012.
[0040] The second support member 16 is connected to the stacked portion 121 and slidably connected to the track 32. The first support member 14 is connected to the junction of the clearance portion 123 and the stacked portion 121 and slidably connected to the track 32. The first support member 14 and the second support member 16 together drive the entire hinge 12 to move along the track 32.
[0041] In this embodiment, the guide rail 30 is connected to the first support 14 and the second support 16, and is used to restrict the movement direction of the hinge 12 to achieve switching between the first position and the second position. This specification does not limit the specific structural shape of the guide rail 30; the shape of the guide rail 30 can be set according to the structure of the air outlet body 201 of the air outlet device 200. As an example, the air outlet body 201 has an annular air outlet 2012, and the guide rail 30 can be set in the shape of a circular plate, positioned at the center of the annular air outlet 2012, thereby facilitating the hinge 12 to block or expose the air outlet 2012. In this embodiment, the guide rail 30 is in the shape of a circular plate, and the center of the guide rail 30 is collinear with a preset center A.
[0042] Track 32 is provided on guide rail 30. Track 32 may include a first linear guide rail 321 and a second linear guide rail 323. The first linear guide rail 321 extends in a direction from a second position to a first position, and the second linear guide rail 323 extends in the same direction. The second linear guide rail 323 is parallel to the first linear guide rail 321 and is spaced apart from the first linear guide rail 321 in a direction perpendicular to the extension of the guide rail. A first support member 14 is slidably inserted through the first linear guide rail 321, and a second support member 16 is slidably inserted through the second linear guide rail 323. In the direction from the second position to the first position, the length of the first linear guide rail 321 in that direction is greater than or equal to the width of the hinge 12 in that direction.
[0043] The guide rail 30 has at least three tracks 32, each corresponding to one of the at least three opening / closing units 10. As an example, the number of opening / closing units 10 is four, and the number of tracks 32 is also four. Four first linear guide rails 321 extend from their respective second positions to their first positions along the opening / closing flaps 12. The first linear guide rails 321 penetrate the guide rail 30 along its thickness direction. Within one track 32, a second linear guide rail 323 is parallel to and spaced apart from the first linear guide rail 321. In this example, there are four opening / closing flaps 12, and the central angle of each flap 12 is approximately 90°. The positions of the first linear guide rails 321 and the second linear guide rails 323 are determined based on the positions of the first support members 14 and 16 on the flaps 12.
[0044] This specification does not limit the specific positions of the first support member 14 and the second support member 16 relative to the hinge 12. For example, the first support member 14 can be connected to the middle, end, or other positions of the hinge 12, and the second support member 16 can also be connected to the middle, end, or other positions of the hinge 12. In this embodiment, the first support member 14 is connected at the connection between the clearance portion 123 and the stacked portion 121, and is approximately located in the middle of the side of the hinge 12 near the preset center A. The second support member 16 can be connected to the end of the side of the hinge 12 near the preset center A. The guide rail 30 is circular and corresponds to the position of the first support member 14. The extension direction of the first linear guide rails 321 is approximately the same as the radial direction of the guide rail 30. All four first linear guide rails 321 extend approximately along the radial direction of the guide rail 30, and the included angle between two adjacent first linear guide rails 321 is approximately 90°. The first support member 14 is located in the middle of the hinge 12, which improves the stability of the hinge 12 driven by the drive assembly 50.
[0045] The drive assembly 50 is connected to the first support member 14 and the second support member 16, and is used to drive the hinge 12 to move along the track 32. In this embodiment, the drive assembly 50 may include a rotary drive member 52 and a transmission disk 54. The transmission disk 54 is driveably connected to the rotary drive member 52 and is stacked on one side of the guide rail member 30. The rotation axis of the transmission disk 54 coincides with the preset center A. The transmission disk 54 has at least three drive guide rail groups 541, and the at least three drive guide rail groups 541 are correspondingly arranged with at least three tracks 32 and at least three opening and closing units 10. The first support member 14 and the second support member 16 are both connected to the corresponding drive guide rail groups 541. The rotary drive member 52 is used to drive the transmission disk 54 to rotate relative to the guide rail member 30 so as to drive the first support member 14 and the second support member 16 to move along the track 32 through the drive guide rail groups 541.
[0046] The rotary drive 52 drives the transmission disk 54 to rotate relative to the guide rail 30. When the transmission disk 54 rotates, it drives the guide rail assembly 541 to rotate as well, thereby driving the first support 14 and the second support 16 to move along the track 32, realizing the switching of the hinge 12 between the first position and the second position.
[0047] Please also refer to Figure 3 and Figure 4The transmission disk 54 can be disposed on the side of the guide rail 30 near the hinge 12, or on the side of the guide rail 30 away from the hinge 12. In this embodiment, the transmission disk 54 is disposed between the hinge 12 and the guide rail 30. The transmission disk 54 is disc-shaped and coaxial with the guide rail 30, and the outer diameter of the transmission disk 54 can be the same as that of the guide rail 30. This specification does not limit the specific structure of the rotary drive component 52. For example, the rotary drive component 52 may include a rotary motor, a rotary cylinder, or other drive sources. The rotary drive component 52 may also include a gear transmission structure, a worm gear transmission structure, a rack and pinion transmission structure, etc. In this embodiment, the rotary drive component 52 may include a motor, a gear set (not shown in the figure), and a drive shaft 521. The drive shaft 521 passes through the guide rail 30 and is fixedly connected to the transmission disk 54. The motor and the gear set can be disposed on the side of the guide rail 30 away from the transmission disk 54, and the motor is connected to the drive shaft 521 through the gear set.
[0048] In this embodiment, the drive guide rail assembly 541 consists of multiple guide rail slots formed in the transmission disk 54. The drive guide rail assembly 541 may include a first transmission guide rail 5412 and a second transmission guide rail 5414. The projections of the first transmission guide rail 5412 and the first linear guide rail 321 along the direction of rotation axis at least partially overlap, and the projections of the second transmission guide rail 5414 and the second linear guide rail 323 along the direction of rotation axis at least partially overlap. The first transmission guide rail 5412 and the second transmission guide rail 5414 are spaced apart, with the first transmission guide rail 5412 communicating with the first linear guide rail 321 and the second transmission guide rail 5414 communicating with the second linear guide rail 323. A first support member 14 passes through the first transmission guide rail 5412 and the first linear guide rail 321, and a second support member 16 passes through the second transmission guide rail 5414 and the second linear guide rail 323. The rotational motion of the transmission disc 54 is converted into the linear movement of the first support member 14 through the cooperation of the first transmission guide rail 5412 and the first support member 14, and into the linear movement of the second support member 16 through the cooperation of the second transmission guide rail 5414 and the second support member 16.
[0049] The rotary drive 52 is used to drive the transmission disk 54 to rotate relative to the guide rail 30 so that the first transmission guide rail 5412 drives the first support 14 to move within the first linear guide rail 321, and the second transmission guide rail 5414 drives the second support 16 to move within the second linear guide rail 323.
[0050] The drive rail assembly 541 can drive the transmission disk 54 to rotate around its own axis. When the transmission disk 54 rotates, the first transmission rail 5412 guides the first support member 14 to move along the first linear guide rail 321, and the second transmission rail 5414 guides the second support member 16 to move along the second linear guide rail 323, thereby realizing the switching of the hinge 12 between the first position and the second position. In order to ensure that the first support member 14 and the second support member 16 can move stably within the corresponding first linear guide rail 321 and second linear guide rail 323, the shape and size of the first transmission rail 5412 and the second transmission rail 5414 are designed to match the first linear guide rail 321 and the second linear guide rail 323.
[0051] Specifically, the first transmission guide rail 5412 and the second transmission guide rail 5414 are formed by a single arc segment to form an arc-shaped guide rail, and the bending direction of the first transmission guide rail 5412 and the second transmission guide rail 5414 is in the same direction in the circumferential direction of the transmission disk 54, so as to ensure that the direction of pushing the first support member 14 and the second support member 16 is consistent.
[0052] The extension directions of the first transmission guide rail 5412 and the second transmission guide rail 5414 are determined according to the switching path of the hinge 12 between the first position and the second position, to ensure that the hinge 12 can smoothly and accurately switch from the first position to the second position, or from the second position to the first position. In this embodiment, the first transmission guide rail 5412 extends according to a first curve, with the two ends of the first curve corresponding to the first position and the second position, respectively. The second transmission guide rail 5414 extends according to a second curve, with the two ends of the second curve corresponding to the first position and the second position, respectively. The concave sides of the first curve and the second curve are oriented in the same direction in the circumferential direction of the transmission disk 54. The first curve can be understood as the inner or outer line of the outline of the first transmission guide rail 5412, and the second curve can be understood as the inner or outer line of the outline of the second transmission guide rail 5414. Figure 4 As shown, the concave sides of both the first and second curves face counterclockwise from the transmission disc 54. Because the hinge 12 is an arc-shaped blade, and the positions of the first support 14 and the second support 16 are different, the curvature of the first and second curves is also different.
[0053] The first transmission guide rail 5412 has a first inner end 5411 and a first outer end 5413, and the first linear guide rail 321 has a second inner end 3212 and a second outer end 3214. The second inner end 3212 is located in a first position, and the second outer end 3214 is located in a second position. The first inner end 5411 and the second inner end 3212 are located on the same circumference of the rotation axis, and the first outer end 5413 and the second outer end 3214 are located on the same circumference of the rotation axis. When the hinge 12 is in the first position, the first inner end 5411 overlaps with the second inner end 3212; when the hinge 12 is in the second position, the first outer end 5413 overlaps with the second outer end 3214. The second transmission guide rail 5414 has a third inner end 5415 and a third outer end 5416, and the second linear guide rail 323 has a fourth inner end 3231 and a fourth outer end 3233. The fourth inner end 3231 is located in the first position, and the fourth outer end 3233 is located in the second position. The third inner end 5415 and the fourth inner end 3231 are located on the same circumference of the rotation axis, and the third outer end 5416 and the fourth outer end 3233 are located on the same circumference of the rotation axis. When the hinge 12 is in the first position, the third inner end 5415 overlaps with the fourth inner end 3231; when the hinge 12 is in the second position, the third outer end 5416 overlaps with the fourth outer end 3233.
[0054] The two ends of the first transmission guide rail 5412 correspond to the two ends of the first linear guide rail 321, and the two ends of the second transmission guide rail 5414 correspond to the two ends of the second linear guide rail 323, so that the first transmission guide rail 5412 can drive the first support member 14 to move from one end of the first linear guide rail 321 to the other end, and the second transmission guide rail 5414 can drive the second support member 16 to move from one end of the second linear guide rail 323 to the other end.
[0055] Please also refer to Figure 4 and Figure 5 Multiple first linear guides 321 are located on the same reference plane B. Second linear guides 323 are provided with limiting inner grooves 3232. The limiting inner groove 3232 has a first end 3201 located at a second position and a second end 3203 located at the first position. The reference plane B passes through the second end 3203. The first end 3201 is located on the side of the reference plane B away from the hinge 12 and is spaced apart from the reference plane B. One end of the second support member 16 is embedded in the limiting inner groove 3232. In this embodiment, the reference plane B can be understood as the surface of the guide rail member 30 away from the transmission disk 54. Multiple first linear guides 321 can be opened from the surface of the guide rail member 30 away from the transmission disk 54. The reference plane B passes through the second end 3203, and the first end 3201 is spaced apart from the reference plane B, such as... Figure 5As shown, the limiting inner groove 3232 is formed on the inner side wall of the second linear guide 323, and the limiting inner groove 3232 gradually tilts downward in the direction from the first end 3201 to the second end 3203.
[0056] The different distances of the first end 3201 and the second end 3203 relative to the reference plane B cause the limiting inner groove 3232 to tilt relative to the reference plane B. When the second support member 16 moves along the second linear guide rail 323 under the drive of the second transmission guide rail 5414, the second support member 16 simultaneously slides within the limiting inner groove 3232. Guided by the tilt of the limiting inner groove 3232, the height of the second support member 16 changes, thereby causing the end of the hinge 12's stacked portion 121 away from the avoidance portion 123 to lift or press down. The second support member 16 is located at the end of the hinge 12, increasing the range of the hinge 12's flipping angle.
[0057] As an example, when the hinge 12 switches from the second position to the first position, the second support member 16 moves from the first end 3201 to the second end 3203, causing one end of the hinge 12 to gradually press down. Simultaneously, the hinges 12 of multiple opening and closing units 10 undergo a slight flipping motion under the influence of their corresponding second support members 16, with the ends of adjacent hinges 12 staggered. This allows the multiple hinges 12 to be stacked on top of each other in the first position, making storage easier. When the hinge 12 switches from the first position to the second position, the second support member 16 moves from the second end 3203 to the first end 3201, causing one end of the hinge 12 to gradually rise. Simultaneously, the hinges 12 of multiple opening and closing units 10 undergo a slight flipping motion under the influence of their corresponding second support members 16, with the ends of adjacent hinges 12 approaching each other. This allows the multiple hinges 12 to form a flush, annular closed structure in the second position, resulting in a flat and aesthetically pleasing appearance.
[0058] To further improve the smoothness of the annular closed structure formed by the multiple hinges 12 in the second position, in this embodiment, the stacked portion 121 is provided with an overlap groove 1212, and the avoidance portion 123 is provided with an overlap portion 1232. In the second position, the overlap portion 1232 of one avoidance portion 123 overlaps with the overlap groove 1212 on the stacked portion 121 of the adjacent hinge, so that the avoidance portion 123 and the other parts of the stacked portion 121 of the adjacent hinge are smoothly connected. As an example, if the four hinges 12 respectively include a first hinge, a second hinge, a third hinge, and a fourth hinge, in the second position, the first hinge, the second hinge, the third hinge, and the fourth hinge are connected end to end. The overlapping portion 121 of the first hinge is located below the clearance portion 123 of the fourth hinge. The overlapping portion 1232 of the clearance portion 123 of the fourth hinge overlaps with the overlapping groove 1212 on the overlapping portion 121 of the first hinge. The overlapping portion 1232 of the clearance portion 123 of the first hinge overlaps with the overlapping groove 1212 on the overlapping portion 121 of the second hinge. The surfaces of the first hinge, the second hinge, the third hinge, and the fourth hinge that form a ring-shaped closed structure are flush.
[0059] Please also refer to Figure 3 , Figure 4 and Figure 6 In this embodiment, the first support member 14 is connected between the guide rail member 30 and the transmission disk 54, and is used to drive the hinge 12 to move along the track 32 under the drive of the transmission disk 54. In this embodiment, the first support member 14 may include a sliding part 141 and a connecting shaft 143 connected to each other. The sliding part 141 is slidably embedded in the first linear guide rail 321, and the connecting shaft 143 is rotatably connected to the hinge 12. The sliding part 141 passes through the first transmission guide rail 5412 and the first linear guide rail 321, and the sliding part 141 may be a sliding rod. In order to prevent the sliding part 141 from disengaging from the first linear guide rail 321 and the first transmission guide rail 5412, in this embodiment, the first support member 14 may further include a limiting part 145. The limiting part 145 is connected to one end of the sliding part 141 away from the connecting shaft 143. The limiting part 145 is located on the side of the guide rail member 30 away from the transmission disk 54, and the dimension of the limiting part 145 in the width direction of the first linear guide rail 321 is greater than the width of the first linear guide rail 321.
[0060] The axial direction of the connecting shaft 143 is approximately perpendicular to the extending direction of the sliding part 141, and the connecting shaft 143 is rotatably connected to the hinge 12. For example, a bearing seat may be provided on the hinge 12, and the connecting shaft 143 is rotatably inserted into the bearing seat, thereby achieving a rotatable connection with the hinge 12. In this embodiment, the axial direction of the connecting shaft 143 is approximately parallel to the direction from the second position of the hinge 12 to the first position. When the hinge 12 switches between the first and second positions, the second support member 16 causes one end of the hinge 12 to be lifted or pressed down, causing the hinge 12 to rotate around the connecting shaft 143.
[0061] Please refer to it again. Figure 4 and Figure 5 In this embodiment, the second support member 16 has an embedded end 161 and a rotating end 163, located at opposite ends of the second support member 16. The embedded end 161 is embedded within the limiting inner groove 3232, and the rotating end 163 is rotatably connected to the hinge 12. The rotating end 163 includes any one of the following structures: a ball joint or a universal joint. To improve the stability of the fit between the embedded end 161 and the limiting inner groove 3232, the outer wall of the embedded end 161 is provided with an arc surface that conforms to the shape of the inner wall of the limiting inner groove 3232. The rotating end 163 is rotatably connected to the hinge 12 to prevent the second support member 16 from getting stuck when moving under the restriction of the limiting inner groove 3232. In this embodiment, the rotating end 163 is a ball joint structure.

When the air outlet device 200 needs to discharge air, the drive component 50 drives the at least three opening and closing flaps 12 to move synchronously along the corresponding track 32, and the at least three opening and closing flaps 12 move from their respective second positions to their respective first positions. At this time, the opening and closing flaps 12 no longer close the air outlet 2012, the air outlet 2012 is connected to the outside, and the air outlet device 200 can discharge air through the air outlet 2012. When each opening and closing flap 12 is in the corresponding first position, at least part of the structure of two adjacent opening and closing flaps 12 overlaps each other to avoid interference when the opening and closing flaps 12 make way for the air outlet 2012.
[0063] The opening and closing mechanism 100 provided in this application synchronously drives at least three opening and closing flaps 12 to move along the corresponding tracks 32, so as to achieve simultaneous opening and closing and reduce the phenomenon of action delay or displacement deviation of the opening and closing flaps 12; the air outlet 2012 opens and closes continuously, improving the user experience and reducing the possibility of problems such as vortex noise caused by discontinuous airflow channels.
