Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a connecting rod driving assembly and an air conditioner. Background Art

[0002] Air conditioners, also known as air conditioners, are widely used to manually adjust the temperature, humidity, and flow rate of ambient air. Related art air conditioners include an air guide door and a connecting rod drive assembly for driving the air guide door. The connecting rod drive assembly drives the air guide door, allowing the air guide door to adjust the direction of airflow.

[0003] However, the connecting rod drive assembly provided by the related art occupies a large installation space, is difficult to meet the requirements of miniaturized design, and has a poor user experience. Summary of the Invention

[0004] The problem solved by the present invention is to reduce the installation space occupied by the connecting rod drive assembly, which is beneficial to the miniaturized design of the air conditioner and improves the user experience.

[0005] To solve the above problems, the present invention provides a connecting rod drive assembly for an air conditioner. The air conditioner has an installation space for installing the connecting rod drive assembly. The connecting rod drive assembly includes:

[0006] a first connecting rod, the first connecting rod being movably disposed in the installation space and capable of being transmission-connected to the air guide door driving mechanism of the air conditioner, the first connecting rod having a bent portion;

[0007] The second connecting rod, one end of the second connecting rod is rotatably connected to the first connecting rod, and the other end of the second connecting rod can be connected to the air guide door of the air conditioner; the first connecting rod and the second connecting rod can extend or retract into the installation space to drive the air guide door to move, and when the first connecting rod and the second connecting rod are retracted into the installation space, the two are folded and distributed.

[0008] Since the first connecting rod has a bending portion, and when the first connecting rod and the second connecting rod are retracted into the installation space, the two are distributed in a folded shape, so the installation space occupied by the first connecting rod and the second connecting rod is reduced, that is, the installation space occupied by the connecting rod drive assembly is reduced, which is conducive to miniaturized design and improves user experience.

[0009] In an optional embodiment, the first connecting rod includes a first rod and a second rod, the first rod is used to be transmission-connected to the air guide door drive mechanism, and the first rod and the second rod are connected at an angle to form a bending portion, and the end of the second rod away from the first rod is rotationally connected to one end of the second connecting rod.

[0010] By rotatably connecting the end of the second rod away from the first rod to one end of the second connecting rod, the space occupied by the first connecting rod and the second connecting rod can be effectively reduced when the first connecting rod and the second connecting rod are retracted into the installation space, which is conducive to miniaturized design and improves user experience.

[0011] In an optional embodiment, the included angle between the first rod and the second rod is 55°-65°.

[0012] Such an arrangement can reduce the installation space occupied by the first connecting rod and the second connecting rod while ensuring that the first connecting rod and the second connecting rod can smoothly extend or retract into the installation space, thereby reliably driving the air guide door to move.

[0013] In an alternative embodiment, the length of the first rod is greater than the length of the second rod.

[0014] Such an arrangement can reduce the installation space occupied by the first and second connecting rods while ensuring that the first connecting rod can smoothly extend or retract into the installation space and reliably drive the second connecting rod to extend or retract into the installation space, thereby reliably driving the air guide door to move.

[0015] In an optional embodiment, the connecting rod drive assembly includes a drive box, which can be set in the installation space, and the first connecting rod and the second connecting rod can be movably set in the drive box and can be extended or retracted relative to the drive box.

[0016] By providing the drive box, the drive box is utilized to protect the first connecting rod and the second connecting rod, reducing interference such as collision between the two, thereby ensuring the reliability of the movement of the first connecting rod and the second connecting rod.

[0017] In an optional embodiment, the connecting rod driving assembly further includes a guide member, which is disposed in the driving box and can contact the second connecting rod to guide the movement of the second connecting rod.

[0018] By guiding the movement of the second connecting rod through the guide member, the second connecting rod can be reliably extended or retracted into the installation space, thereby reliably driving the air guide door to move.

[0019] In an alternative embodiment, the drive box includes an opening, and the first connecting rod and the second connecting rod can be extended from the opening or retracted relative to the drive box; and the guide member is disposed adjacent to the opening.

[0020] The guide member is arranged at a position adjacent to the opening of the drive box, so that the guide member can be used to guide the second connecting rod to extend from the opening or retract into the drive box more stably, thereby driving the air guide door to move more stably.

[0021] The present invention also provides an air conditioner, comprising:

[0022] The connecting rod drive assembly of any of the preceding embodiments;

[0023] The housing has an installation space, and the connecting rod drive assembly is arranged in the installation space;

[0024] An air guide door, the air guide door is movably arranged on the shell;

[0025] An air guide door driving mechanism, the air guide door driving mechanism is arranged on the housing;

[0026] Among them, the air guide door driving mechanism is connected to the first connecting rod of the connecting rod driving assembly, and the second connecting rod of the connecting rod driving assembly is connected to the air guide door. The air guide door driving mechanism can drive the first connecting rod and the second connecting rod to extend or retract the installation space to drive the air guide door to move.

[0027] Since the first connecting rod of the connecting rod drive assembly has a bending portion, and the first connecting rod and the second connecting rod are distributed in a folded shape when they are retracted into the installation space, the installation space occupied by the first connecting rod and the second connecting rod is reduced, that is, the installation space occupied by the connecting rod drive assembly is reduced, which is conducive to the miniaturization design of the air conditioner and improves the user experience.

[0028] In an optional embodiment, the shell includes a middle frame and an end cover, the end cover is arranged on the middle frame, and an installation space is formed between the end cover and the middle frame.

[0029] By arranging the connecting rod drive assembly in the installation space formed between the middle frame and the end cover, the first connecting rod and the second connecting rod can be arranged between the middle frame and the end cover, improving the problem that the two are prone to interfere with other components of the air conditioner, thereby ensuring that the first connecting rod and the second connecting rod can move smoothly and reliably drive the air guide door to move.

[0030] In an optional embodiment, the air guide door driving mechanism is arranged on a side of the middle frame facing away from the installation space.

[0031] By arranging the air guide door drive mechanism on the side of the middle frame away from the installation space, the number of components assembled in the installation space can be reduced, thereby reducing the installation space, which is conducive to the miniaturization design of the air conditioner and improves the user experience.

DETAILED DESCRIPTION

[0040] Air conditioners are widely used to regulate ambient air temperature, humidity, and other factors. Related art air conditioners include an air guide door and a connecting rod drive assembly for actuating the door. The connecting rod drive assembly actuates the door, allowing the door to adjust the direction of airflow. However, the connecting rod drive assembly used in related art takes up a significant amount of installation space, making it difficult to meet the requirements of miniaturized air conditioner designs and resulting in a poor user experience.

[0041] The connecting rod drive assembly provided by the present invention occupies a small installation space, is conducive to the miniaturization design of the air conditioner, and improves the user experience.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] The air conditioner 010 (such as Figure 1 As shown) can be used to adjust the temperature and humidity of the ambient air, etc.

[0044] The air conditioner 010 includes an indoor air conditioner, such as a wall-mounted indoor air conditioner or a floor-mounted indoor air conditioner. Optionally, the air conditioner 010 also includes an outdoor air conditioner used in conjunction with the indoor air conditioner. The indoor air conditioner will be described in detail below.

[0045] The air conditioner 010 includes a shell 100, an air guide door 110, an air guide door driving mechanism, a heat exchanger (not shown in the figure) and a fan (not shown in the figure). The shell 100 is provided with an air outlet 111. The heat exchanger, the fan and the air guide door driving mechanism are all arranged in the shell 100. The air guide door 110 is pivotally connected to the shell 100, and the air guide door driving mechanism is coordinated with the air guide door 110 for driving the air guide door 110 to move relative to the shell 100 to close or open the air outlet 111.

[0046] It should be noted that when the air guide door driving mechanism drives the air guide door 110 to open the air outlet 111, the air heated by the heat exchanger can be blown out of the air outlet 111 by the fan. When the air guide door driving mechanism drives the air guide door 110 to move to different positions, the air outlet direction of the air outlet 111 can be adjusted to meet different needs. When the air guide door driving mechanism drives the air guide door 110 to close the air outlet 111, the air guide door 110 can be used to block the air outlet 111, thereby reducing the entry of dust and the like into the interior of the air conditioner 010.

[0047] Please combine Figure 1 、 Figure 2 and Figure 3 The shell 100 includes a middle frame 120 and a base (not shown in the figure). The base is arranged on the middle frame 120. The heat exchanger and the fan are both arranged on the base. The middle frame 120 is provided with an air outlet 111, and the air guide door 110 is pivotally connected to the middle frame 120. The air guide door driving mechanism is arranged on the middle frame 120.

[0048] Please continue to refer to Figure 1 and Figure 3 The air conditioner 010 of this embodiment further includes a connecting rod driving assembly 200, and the air guide door driving mechanism is connected to the air guide door 110 through the connecting rod driving assembly 200. In this way, the air guide door driving mechanism can use the connecting rod driving assembly 200 to drive the air guide door 110 to move.

[0049] Furthermore, the housing 100 has an installation space 140 , and the connecting rod driving assembly 200 is disposed in the installation space 140 .

[0050] Furthermore, the shell 100 also includes an end cover 130, which is arranged on the middle frame 120. An installation space 140 is formed between the end cover 130 and the middle frame 120. The connecting rod drive assembly 200 is arranged in the installation space 140 between the end cover 130 and the middle frame 120. This can improve the problem of mutual interference between the connecting rod drive assembly 200 and other components of the air conditioner 010, and ensure that the connecting rod drive assembly 200 can reliably drive the air guide door 110 to move.

[0051] It should be noted that other components of the air conditioner 010 may refer to the heat exchanger and fan installed on the base, or may refer to wires, refrigerant pipes, air ducts and other pipelines connected to the heat exchanger or fan and other components, and are not specifically limited here.

[0052] In this embodiment, the air guide door driving mechanism is arranged on the side of the middle frame 120 away from the installation space 140; in this way, the components assembled in the installation space 140 can be reduced, thereby reducing the installation space 140, which is conducive to the miniaturization design of the air conditioner 010 and improving the user experience.

[0053] Of course, in other embodiments, the air guide door driving mechanism may be disposed in the installation space 140 .

[0054] It should be noted that the air guide door driving mechanism can be selected as needed. The air guide door driving mechanism of this embodiment includes a motor 150, which is arranged on the side of the middle frame 120 away from the installation space 140, and the output shaft of the motor 150 can extend into the installation space 140 and be connected to the connecting rod driving assembly 200 for transmission, so that when the output shaft of the motor 150 rotates, the connecting rod driving assembly 200 is driven to drive the air guide door 110 to move relative to the shell 100.

[0055] Of course, in other embodiments, the air guide door driving mechanism further includes a gear drivingly connected to the output shaft of the motor 150 , and the gear can be drivingly connected to the connecting rod driving assembly 200 , which is not specifically limited here.

[0056] Please refer to Figure 1 、 Figure 3 and Figure 4 The connecting rod drive assembly 200 of this embodiment includes a first connecting rod 210 and a second connecting rod 220. The first connecting rod 210 is movably arranged in the installation space 140 and is transmission-connected to the air guide door driving mechanism, that is, the first connecting rod 210 is transmission-connected to the output shaft of the motor 150; the first connecting rod 210 has a bending portion 213; one end of the second connecting rod 220 is rotationally connected to the first connecting rod 210, and the other end of the second connecting rod 220 is connected to the air guide door 110; the first connecting rod 210 and the second connecting rod 220 can extend or retract into the installation space 140 to drive the air guide door 110 to move, and when the first connecting rod 210 and the second connecting rod 220 are retracted into the installation space 140, the two are folded and distributed.

[0057] Since the first connecting rod 210 has a bending portion 213, and when the first connecting rod 210 and the second connecting rod 220 are retracted into the installation space 140, the two are distributed in a folded shape, so the installation space 140 occupied by the first connecting rod 210 and the second connecting rod 220 is reduced, that is, the installation space 140 occupied by the connecting rod drive assembly 200 is reduced, which is conducive to the miniaturized design of the air conditioner 010 and improves the user experience.

[0058] It should be noted that an installation space 140 is formed between the end cover 130 and the middle frame 120, and the first connecting rod 210 and the second connecting rod 220 of the connecting rod drive assembly 200 are movably arranged in the installation space 140, so that the first connecting rod 210 and the second connecting rod 220 can be arranged between the middle frame 120 and the end cover 130, thereby improving the problem that the two are prone to interfere with each other with other components of the air conditioner 010, thereby ensuring that the first connecting rod 210 and the second connecting rod 220 can move smoothly and reliably drive the air guide door 110 to move.

[0059] Please continue to refer to Figure 1 and Figure 4 In this embodiment, the first connecting rod 210 includes a first rod 211 and a second rod 212. The first rod 211 is in transmission connection with the air guide door drive mechanism, specifically, the first rod 211 is in transmission connection with the output shaft of the motor 150. The first rod 211 and the second rod 212 are connected at an angle to form a bend 213. The end of the second rod 212, away from the first rod 211, is rotatably connected to one end of the second connecting rod 220. When the output shaft of the motor 150 drives the first rod 211 to rotate, the first rod 211 drives the second rod 212 to rotate synchronously. The second rod 212 then drives the second connecting rod 220 to move, allowing the second rod 212 and the second connecting rod 220 to extend or retract into the installation space 140, thereby driving the air guide door 110 to move.

[0060] By rotatably connecting the end of the second rod 212 away from the first rod 211 to one end of the second connecting rod 220, the space occupied by the first connecting rod 210 and the second connecting rod 220 can be effectively reduced when both are retracted into the installation space 140, which is conducive to miniaturization design and improves user experience.

[0061] It should be noted that when the first link 210 and the second link 220 are retracted into the installation space 140, the second link 220 is opposite to the first rod 211 and is spaced apart, and the second link 220 and the second rod 212 are distributed at an angle, so that the first link 210 and the second link 220 are distributed in a folded shape, which can reduce the volume of the first link 210 and the second link 220 when they are retracted into the installation space 140, thereby making the installation space 140 form a miniaturized and compact design.

[0062] It should also be noted that one end of the first rod 211 away from the second rod 212 is in driving connection with the output shaft of the motor 150 , so as to further reduce the space occupied by the first rod 211 and further ensure a compact structural design.

[0063] Please refer to Figure 5The angle α between the first rod 211 and the second rod 212 can be selected as needed. For example, the angle α between the first rod 211 and the second rod 212 can be 55°-65°. In this way, while reducing the space occupied by the first connecting rod 210 and the second connecting rod 220 when they are retracted into the installation space 140, it can also ensure that the first connecting rod 210 and the second connecting rod 220 can smoothly drive the air guide door 110 to move.

[0064] In a preferred embodiment, the angle α between the first rod 211 and the second rod 212 is 60°; in this way, while ensuring that the space occupied by the first connecting rod 210 and the second connecting rod 220 when retracted into the installation space 140 is reduced, it can also ensure that the first connecting rod 210 and the second connecting rod 220 can stably and reliably extend or retract into the installation space 140, thereby smoothly driving the air guide door 110 to move.

[0065] Of course, in other embodiments, the angle α between the first rod 211 and the second rod 212 may also be 50°, 55°, 67°, etc., which is not specifically limited here.

[0066] The lengths of the first rod 211 and the second rod 212 can be selected as needed. Figure 4 In this embodiment, the length of the first rod 211 is greater than the length of the second rod 212, so that when the motor 150 drives the first rod 211 to rotate, the second rod 212 can be driven to rotate synchronously more effortlessly and smoothly, thereby reducing the installation space 140 occupied by the first connecting rod 210 and the second connecting rod 220 while ensuring that the first connecting rod 210 can smoothly extend or retract into the installation space 140, and reliably drive the second connecting rod 220 to extend or retract into the installation space 140, thereby reliably driving the air guide door 110 to move.

[0067] Furthermore, in this embodiment, the first connecting rod 210 is configured so that when the second connecting rod 220 is fully extended out of the installation space 140, the first rod 211 is located in the installation space 140; in this way, it is convenient to ensure the structural stability of the connecting rod drive assembly 200, and thus it is beneficial to use the connecting rod drive assembly 200 to reliably drive the air guide door 110 to move.

[0068] Of course, in other embodiments, the length of the first rod 211 may also be equal to or less than the length of the second rod 212 , which is not specifically limited here.

[0069] The shape of the second connecting rod 220 can be selected as needed. The second connecting rod 220 of this embodiment is an arc-shaped rod. When the motor 150 drives the first connecting rod 210 to rotate, the arc-shaped second connecting rod 220 can be smoothly extended or retracted into the installation space 140 under the drive of the first connecting rod 210, thereby reliably driving the air guide door 110 to move.

[0070] Of course, in other embodiments, the second connecting rod 220 may also be a linear rod, which is not specifically limited here.

[0071] Please refer to Figure 4 、 Figure 5 and Figure 6 The connecting rod driving assembly 200 of this embodiment further includes a driving box 230, which is disposed in the installation space 140. The first connecting rod 210 and the second connecting rod 220 are both movably disposed in the driving box 230 and can extend or retract relative to the driving box 230. The driving box 230 is provided to protect the first connecting rod 210 and the second connecting rod 220, thereby reducing interference such as collisions between the first connecting rod 210 and the second connecting rod 220, thereby ensuring the reliability of the movement of the first connecting rod 210 and the second connecting rod 220. Moreover, the driving box 230 allows the connecting rod driving assembly 200 to be assembled in the installation space 140 by first assembling the first connecting rod 210 and the second connecting rod 220 in the driving box 230, and then the entire assembly can be modularly assembled in the installation space 140, making assembly easy.

[0072] For further information, please refer to Figure 6 The driving box 230 includes an opening 231, and the first connecting rod 210 and the second connecting rod 220 can extend from or retract into the driving box 230 through the opening 231. When the first connecting rod 210 and the second connecting rod 220 extend from the opening 231 to the driving box 230, they can extend out of the installation space 140. When the first connecting rod 210 and the second connecting rod 220 retract into the driving box 230, they can retract into the installation space 140.

[0073] The shape of the drive box 230 can be selected as needed, please refer to Figure 4 In this embodiment, the interior of the drive box 230 has a guide surface 232, and the guide surface 232 is a circular arc concave surface. The guide surface 232 can contact the second rod 212 to guide the rotation of the first connecting rod 210; specifically, when the motor 150 drives the first connecting rod 210 to rotate, the second rod 212 can slide on the surface of the guide surface 232, so that the first connecting rod 210 can rotate stably, thereby stably driving the second connecting rod 220 to move, and stably driving the air guide door 110 to move.

[0074] In order to make the first rod 211 and the second rod 212 rotate more smoothly, the connection between the first rod 211 and the second rod 212 can be set to a rounded corner; in this way, when the first connecting rod 210 rotates, the connection between the first rod 211 and the second rod 212 can also contact the guide surface 232, that is, the connection between the first rod 211 and the second rod 212 can also slide on the guide surface 232, thereby ensuring that the first connecting rod 210 rotates stably.

[0075] It should be understood that in other embodiments, the guide surface 232 may also contact the second connecting rod 220 or the first rod 211 , which is not specifically limited herein.

[0076] It should be noted that the second rod 212 is adapted to the guide surface 232 of the drive box 230; for details, please refer to Figure 1 The second rod 212 is an arc-shaped rod. When the first connecting rod 210 and the second connecting rod 220 are retracted into the driving box 230, the extension direction of the second rod 212 is consistent with the extension direction of the guide surface 232, so that the second rod 212 fits with the guide surface 232, which is beneficial to reducing the volume of the driving box 230, and then beneficial to the volume of the installation space 140, which is beneficial to miniaturization design.

[0077] When the first connecting rod 210 and the second connecting rod 220 are both retracted into the driving box 230, the second rod 212 is spaced apart from the guide surface 232. In this way, when the motor 150 drives the first connecting rod 210 to rotate in the direction of extending the driving box 230, the friction resistance encountered by the first connecting rod 210 when it starts to rotate can be reduced, thereby ensuring that the first connecting rod 210 can be smoothly rotated to extend the driving box 230.

[0078] In other embodiments, the second rod 212 may also be in surface contact with the guide surface 232 , which is not specifically limited herein.

[0079] The shape of the driving box 230 can be adapted to the shape of the first connecting rod 210 , so that the first connecting rod 210 and the second connecting rod 220 can be retracted into the driving box 230 at the same time, and the miniaturization design of the driving box 230 can be ensured.

[0080] For further information, please refer to Figure 1 and Figure 4 The drive box 230 further includes a first mating surface 233 and a second mating surface 234. One end of the guide surface 232 is adjacent to the opening 231 of the drive box 230, and the other end of the guide surface 232 is connected to the first mating surface 233. A tangent line at the connection between the guide surface 232 and the first mating surface 233 is angled with the first mating surface 233. An end of the first mating surface 233 away from the guide surface 232 is connected to an end of the second mating surface 234 at an angle, and the other end of the second mating surface 234 is adjacent to the opening 231 of the drive box 230. When the first connecting rod 210 and the second connecting rod 220 are both retracted into the drive box 230, the first rod 211 is opposite to the first mating surface 233. When the first connecting rod 210 and the second connecting rod 220 are both extended from the drive box 230, the first rod 211 is opposite to the second mating surface 234. In this way, the volume of the drive box 230 can be minimized, thereby reducing the volume of the installation space 140 occupied by the connecting rod drive assembly 200, which is conducive to miniaturization.

[0081] It should be noted that when the first connecting rod 210 and the second connecting rod 220 are both retracted into the drive box 230, the first rod 211 is opposite to the first mating surface 233, which may mean that the first rod 211 and the first mating surface 233 are spaced apart or in surface contact, and this is not specifically limited here. When the first connecting rod 210 and the second connecting rod 220 are both extended from the drive box 230, the first rod 211 is opposite to the second mating surface 234, which may mean that the first rod 211 and the second mating surface 234 are spaced apart or in surface contact, and this is not specifically limited here.

[0082] It should also be noted that the included angle between the first mating surface 233 and the second mating surface 234 can be selected as needed, for example, 120°, 135°, etc., and is not specifically limited here. The included angle between the tangent line at the junction of the guide surface 232 and the first mating surface 233 and the first mating surface 233 can be 50°, 60°, etc., and is not specifically limited here.

[0083] In order to further ensure the compact structure of the driving box 230, the length of the opening 231 can be reduced as much as possible when the first connecting rod 210 and the second connecting rod 220 can extend from or retract into the driving box 230. For example, the length L of the opening 231 (e.g. Figure 6 As shown in the figure, the driving box 230 is controlled at about 25 mm, and the area occupied by the driving box 230 is about 3782 square millimeters, so as to fully make the structure of the driving box 230 compact.

[0084] The structure of the drive box 230 can be selected as needed, please refer to Figure 5 The drive box 230 of this embodiment includes a first box body 250 and a second box body 260 that are buckled and connected to each other, and the first box body 250 and the second box body 260 are buckled to form an opening 231; the first connecting rod 210 and the second connecting rod 220 can be movably arranged between the first box body 250 and the second box body 260; this facilitates the assembly of the connecting rod drive assembly 200.

[0085] Furthermore, the output shaft of the motor 150 extends between the first housing 250 and the second housing 260 and is tightly plugged into the first rod 211, so that the motor 150 can reliably drive the first connecting rod 210 to rotate. It should be understood that in other embodiments, the output shaft of the motor 150 can also be fixedly connected to the first rod 211 by fasteners, including but not limited to screws or bolts, which are not specifically limited here.

[0086] Please note that, please refer to Figure 5The first box body 250 and the second box body 260 are arranged roughly in mirror symmetry. The first box body 250 has a first guide surface 251, and the second box body 260 has a second guide surface (not shown in the figure). When the first box body 250 and the second box body 260 are buckled and connected, the first guide surface 251 and the second guide surface are spliced ​​to form a guide surface 232.

[0087] Furthermore, the first box body 250 also includes a first surface 252 and a second surface 253, and the second box body 260 also has a third surface and a fourth surface (not shown in the figure). When the first box body 250 and the second box body 260 are buckled and connected, the first surface 252 and the third surface are spliced ​​to form a first mating surface 233, and the second surface 253 and the fourth surface are spliced ​​to form a second mating surface 234.

[0088] Please refer to Figure 4 The connecting rod drive assembly 200 of this embodiment also includes a guide member 240, which is arranged in the drive box 230. The guide member 240 can contact the second connecting rod 220 to guide the movement of the second connecting rod 220; specifically, when the motor 150 drives the first connecting rod 210 to rotate, the first connecting rod 210 drives the second connecting rod 220 to move, and the second connecting rod 220 slides on the surface of the guide member 240, so that the second connecting rod 220 can stably and smoothly extend or retract into the drive box 230, thereby stably and smoothly driving the air guide door 110 to move.

[0089] Furthermore, the guide member 240 is disposed adjacent to the opening 231. Disposing the guide member 240 adjacent to the opening 231 of the drive box 230 allows the second connecting rod 220 to be more stably extended from or retracted into the drive box 230, thereby more stably driving the air guide door 110 to move.

[0090] It should be noted that the guide member 240 can be selected as needed. The guide member 240 of this embodiment is a guide column arranged in the drive box 230, and the central axis of the guide column is parallel to the rotation axis of the air guide door 110; when the motor 150 drives the first connecting rod 210 to rotate, the first connecting rod 210 drives the second connecting rod 220 to move, and the second connecting rod 220 can slide on the outer wall of the guide column so that the second connecting rod 220 can stably extend or retract the drive box 230.

[0091] Of course, in other embodiments, the guide member 240 may be a roller disposed in the drive box 230 , which is not specifically limited here.

[0092] In some embodiments, the guide member 240 can also contact the first connecting rod 210, specifically, the guide member 240 can contact the second rod 212; in this way, when the motor 150 drives the first connecting rod 210 to rotate, the first connecting rod 210 can rotate until the second rod 212 contacts the guide member 240, and the second rod 212 can slide on the surface of the guide member 240 so that the second rod 212 can stably extend or retract the drive box 230.

[0093] When in use, the air conditioner 010 of this embodiment can utilize the motor 150 to drive the first connecting rod 210 to rotate, so as to utilize the first connecting rod 210 to drive the second connecting rod 220 to move, thereby controlling the movement of the air guide door 110, thereby opening or closing the air outlet 111 of the air conditioner 010, or adjusting the air outlet direction of the air outlet 111.

[0094] In summary, the connecting rod drive assembly 200 of the present invention can be used in the air conditioner 010, and the connecting rod drive assembly 200 occupies a small installation space 140, which is conducive to the miniaturization design of the air conditioner 010 and improves the user experience.

[0095] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
