[0002] At present, a corresponding shielding door panel is usually provided at the air outlet of the indoor unit of the air conditioner. The shielding door panel can automatically move under the drive of the driving mechanism inside the air conditioner to shield and close the air outlet, or avoid and open the air outlet.

[0003] In the prior art, the driving form of the driving mechanism usually relies on a servo motor and a simple transmission component that cooperates with it to achieve the corresponding driving action.

[0004] However, due to the accumulation of processing errors of various components and the accumulation of deformation during the long-term operation of the air conditioner, the fit between the transmission parts in the transmission assembly will no longer be tight and gaps will appear. At this time, the servo motor drives the shielding door panel to move through the transmission assembly, and the shielding door panel will inevitably vibrate and shake. Some shielding door panels with complex structures (such as those equipped with corresponding structures inside the air conditioner to prevent the shielding door panel from deformation) will also collide with the internal parts of the air conditioner, making noise and affecting the user experience.

[0038] In order to solve the problem of poor movement stability of a shielding door panel of an indoor unit of an air conditioner in the prior art, the present application provides a driving mechanism and an air conditioner having the same.

[0039] like Figures 1 to 9 As shown, at least part of the driving mechanism is arranged in the housing 1 of the air conditioner, and the driving mechanism is connected to the door panel 2 of the air conditioner for driving the door panel 2 to move. The driving mechanism includes: a mounting structure 10; a driving structure 20, which is arranged on the mounting structure 10; a transmission assembly 30, which is arranged on the mounting structure 10 and includes a gear member 31 and a movably arranged driving member 32, the driving member 32 has a rack portion 321 arranged along a preset direction, the rack portion 321 meshes with the gear member 31, the driving member 32 is arranged on the door panel 2, and the driving structure 20 is connected to the gear member 31 for driving the driving member 32 to drive the door panel 2 to move through the meshing cooperation between the gear member 31 and the driving member 32 during the process of driving the gear member 31 to rotate; a pushing member, which is used to apply a pushing force to the driving member 32 toward the gear member 31.

[0040] The technical solution of this embodiment is applied, at least part of the driving mechanism is arranged in the housing 1 of the air conditioner, the driving mechanism is connected to the door panel 2 of the air conditioner for driving the door panel 2 to move, the driving structure 20 of the driving mechanism is arranged on the mounting structure 10, the transmission assembly 30 is arranged on the mounting structure 10 and includes a gear member 31 and a movably arranged driving member 32, the driving member 32 has a rack portion 321 arranged along a preset direction, the rack portion 321 is meshed with the gear member 31, the driving member 32 is arranged on the door panel 2, the driving structure 20 is connected to the gear member 31 for driving the driving member 32 to drive the door panel 2 to move through the meshing cooperation between the gear member 31 and the driving member 32 during the process of driving the gear member 31 to rotate; the pushing member is used to apply a pushing force to the driving member 32 toward the gear member 31. In this way, during the process of the driving structure 20 driving the gear part 31 to rotate so as to drive the driving part 32 to drive the door panel 2 to move through the meshing cooperation between the gear part 31 and the driving part 32, the pushing part can continuously apply a pushing force to the driving part 32 toward the gear part 31 to eliminate the virtual gap between the rack part 321 and the gear part 31, ensuring that the two can be tightly meshed, thereby avoiding the door panel 2 from shaking or vibrating during movement due to the virtual gap between the two, thereby solving the problem of poor movement stability of the shielding door panel of the air conditioner indoor unit in the prior art, reducing the probability of noise generation, and improving the user experience.

[0041] In this embodiment, the preset direction (i.e., the arrangement direction of the rack portion 321) is actually determined according to the movement direction of the door panel 2, that is, the preset direction is parallel to the movement direction of the door panel 2. Specifically, the driving mechanism in this embodiment is actually applied to a cylindrical vertical air conditioner, so the preset direction is an arc-shaped trajectory.

[0042] In this embodiment, the driving structure 20 is a servo motor.

[0043] In this embodiment, the gear member 31 and the rack portion 321 are interference-fitted to ensure a sufficiently high meshing tightness between the two.

[0044] In this embodiment, the push member is an elastic structure 40, and the elastic structure 40 abuts against at least part of the driving member 32, so as to apply a push force to the driving member 32 toward the gear member 31 through the elastic force generated when the elastic structure 40 is elastically deformed. In this way, the above arrangement makes the structure of the push member simpler and easier to process and realize; on the other hand, when the elastic structure 40 abuts against the driving member 32 to apply the elastic force to the driving member 32, it will also generate friction resistance between the driving member 32, and the resistance will have a blocking effect on the driving structure 20, so as to further improve the movement stability of the driving member 32 (i.e., the door panel 2).

[0045] Optionally, the driving member 32 further has a first matching portion 322, and the mounting structure 10 has: a first mounting portion 11, which is used to mount the driving structure 20; and a second mounting portion 12, which is located on the side of the driving structure 20 close to the gear member 31. Among them, one of the first mounting portion 11 and the first matching portion 322 is a first protrusion, and the other of the first mounting portion 11 and the first matching portion 322 is a first recess, the first protrusion extends into the first recess and slides along the extension direction of the first recess, and the first recess extends along a preset direction. In this way, the above arrangement not only allows the driving member 32 to be slidably mounted on the mounting structure 10 through the sliding fit between the second mounting portion 12 and the first matching portion 322, but also makes the structures of the second mounting portion 12 and the first matching portion 322 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0046] like Figure 3 As shown, the first matching portion 322 is a first recess, the second mounting portion 12 is a first protrusion, the elastic structure 40 is located at the end side of the second mounting portion 12, and at least part of the elastic structure 40 extends into the first matching portion 322 to form a deformation section, and the deformation section is elastically deformed by the abutment between its outer peripheral surface and the inner wall of the first matching portion 322. Among them, the deformation section has a first deformation portion 41 and a second deformation portion 42, and the first deformation portion 41 is arranged close to the gear member 31 relative to the second deformation portion 42. When the elastic deformation amount of the first deformation portion 41 is greater than the elastic deformation amount of the second deformation portion 42, the elastic structure 40 applies a thrust force to the driving member 32 to move toward the gear member 31. In this way, the first matching portion 322 can also play a fixing role on the elastic structure 40 to ensure that its inner wall can stably abut against the elastic structure 40 and promote its elastic deformation. At the same time, the above-mentioned arrangement of the first deformation part 41 and the second deformation part 42 not only ensures that the elastic structure 40 can apply a thrust force to the driving member 32 toward the gear member 31, but also enables the driving member 32 to have a certain amount of activity in the radial direction of the gear member 31, thereby enabling the driving member 32 to adapt to the actual movement process of the door panel 2, thereby further improving the movement stability of the door panel 2.

[0047] Specifically, the movement trajectory of the door panel 2 cannot be a completely perfect curve, and it is inevitable that it will move along the radial direction of the gear part 31 during the actual movement process. The above-mentioned setting of the elastic structure 40 can adapt to the above-mentioned movement process, avoid the interference between the door panel 2 and other structures, and thus ensure that the door panel 2 can move stably.

[0048] In this embodiment, the elastic structure 40 is actually a cylindrical rubber member.

[0049] like Figure 3As shown, along the direction from the open end of the first matching portion 322 to the bottom wall of the first matching portion 322, the first matching portion 322 includes a first sub-recess 3221 and a second sub-recess 3222 that are interconnected, the first sub-recess 3221 has an open end, the second mounting portion 12 extends into the second sub-recess 3222, and the elastic structure 40 extends into the first sub-recess 3221. In the radial direction of the gear member 31, the width of the first sub-recess 3221 is smaller than the width of the second sub-recess 3222, so as to form a step surface 3223 on the inner wall of the first matching portion 322, and the step surface 3223 is used for limiting and stopping with the elastic structure 40. In this way, the second mounting portion 12 can actually guide the movement direction of the driving member 32 during the movement of the driving member 32. The above-mentioned arrangement ensures that there is a sufficiently large matching area between the second mounting portion 12 and the first matching portion 322 to ensure that it has a sufficiently high guiding reliability, while avoiding the elastic structure 40 from extending into the first matching portion 322 too large, thereby ensuring that the blocking effect of the elastic structure 40 (the friction resistance between the elastic structure 40 and the first matching portion 322) is relatively appropriate, so as to avoid the contact area between it and the first matching portion 322 being too large, resulting in excessive blocking effect, thereby affecting the movement stability of the driving member 32 (door panel 2).

[0050] In this embodiment, the first matching portion 322 is actually a strip-shaped recess extending along a preset direction.

[0051] In this embodiment, the outer circumferential surface of the cylindrical elastic structure 40 is interference-fitted with the inner wall of the first sub-recess 3221 to ensure that the elastic structure 40 can generate sufficient friction resistance (blocking effect) while fixing the elastic structure 40.

[0052] Optionally, the interference between the elastic structure 40 and an inner side wall of the first sub-recess 3221 is in a range of 0.3 mm to 0.5 mm.

[0053] like Figure 3 As shown, along the radial direction of the gear member 31, the width W1 of the second sub-recess 3222 is greater than the width W2 of the first matching portion 322, so that a movement gap 13 is formed between the second mounting portion 12 and the inner wall of the second sub-recess 3222 along the radial direction of the gear member 31. In the process of elastic deformation of the elastic structure 40, the driving member 32 moves toward or away from the gear member 31 through the movement gap 13. In this way, the setting of the movement gap 13 can ensure that the driving member 32 can be displaced in the radial direction of the gear member 31, that is, to avoid interference between the second mounting portion 12 and the second sub-recess 3222 to affect the follow-up movement of the driving member 32, and further improve the movement stability of the door panel 2.

[0054] like Figure 3 and Figure 7As shown, the second mounting portion 12 includes: a plate-shaped body 121; a contact protrusion 122, which is arranged on the end surface of the plate-shaped body 121 extending into the first matching portion 322, and the contact protrusion 122 is used to contact the bottom wall of the first matching portion 322. In this way, the arrangement of the contact protrusion 122 can effectively reduce the contact area between the second mounting portion 12 and the bottom wall of the first matching portion 322, so as to avoid excessive friction between the two and affect the movement process of the driving member 32, and further improve the movement stability of the door panel 2.

[0055] In this embodiment, the plate-shaped body 121 is an arc-shaped plate to match the motion trajectory of the driving member 32 .

[0056] In this embodiment, there are two plate-like bodies 121, which are arranged at intervals along a preset direction, and the elastic structure 40 is located between the two plate-like bodies 121. There are also two contact protrusions 122, which are arranged at intervals on the upper surface of the plate-like body 121. In this way, the plate-like body 121, the contact protrusion 122 and the elastic structure 40, which are mainly in contact with the driving member 32, adopt the above arrangement method, so that the overall structure is symmetrical to each other, so that the force generated at each contact position is more uniform, which helps to further improve the movement stability of the door panel 2.

[0057] It should be noted that the number of the plate-like body 121 and the contact protrusions 122 is not limited thereto, and can be adjusted according to working conditions and usage requirements.

[0058] In this embodiment, a mounting protrusion 17 is further provided between the two plate-like bodies 121 , and a through hole is provided on the cylindrical elastic structure 40 , and the elastic structure 40 is sleeved on the mounting protrusion 17 through the through hole.

[0059] like Figure 3 , Figure 4 and Figure 7The mounting structure 10 comprises: a mounting base 14 having a first mounting portion 11; a cover member 15, which is covered on the mounting base 14, and at least part of the driving member 32 is located between the mounting base 14 and the cover member 15, so as to form a mounting cavity 16 for accommodating the driving structure 20 and the gear member 31 around the mounting base 14, the cover member 15 and the driving member 32; wherein, the second mounting portion 12 is arranged on the mounting base 14 and / or the cover member 15, when one of the mounting base 14 and the cover member 15 is provided with the second mounting portion 12, the driving member 32 also has a second matching portion 323, and the other of the mounting base 14 and the cover member 15 has a third matching portion 151, one of the second matching portion 323 and the third matching portion 151 is a second protrusion, and the other of the second matching portion 323 and the third matching portion 151 is a second recess, the second protrusion extends into the second recess and can slide along the extension direction of the second recess, and the second recess extends along a preset direction. Thus, the above arrangement, on the one hand, makes the mounting structure 10 a split design as a whole, so that the staff can disassemble and assemble the driving structure 20 and the transmission assembly 30, and then inspect and replace the two; on the other hand, the mounting structure 10 and the driving member 32 can protect the driving structure 20 and the gear member 31 located in the mounting cavity 16. At the same time, the above arrangement also makes the number of second mounting parts 12 more flexible and diverse.

[0060] In this embodiment, the second mounting portion 12 is arranged on the mounting base 14, the driving member 32 also has a second matching portion 323, the other of the mounting base 14 and the cover member 15 has a third matching portion 151, one of the second matching portion 323 and the third matching portion 151 is a second protrusion, the other of the second matching portion 323 and the third matching portion 151 is a second recess, the second protrusion extends into the second recess and can slide along the extension direction of the second recess, and the second recess extends along a preset direction. In this way, since the structures of the second mounting portion 12 and the first matching portion 322 and the elastic structure 40 matched therewith are relatively complex and the processing difficulty is relatively high, this embodiment only adopts the above-mentioned special design on the mounting base 14 (i.e., one side of the driving member 32), and the other side adopts a simple recess / protrusion matching method to reduce the overall processing difficulty and processing cost of the driving mechanism.

[0061] In this embodiment, the second matching portion 323 is a second recess, and the third matching portion 151 is a second protrusion.

[0062] In other embodiments not shown in the drawings, the second matching portion 323 is a second protrusion, and the third matching portion 151 is a second recess.

[0063] In other embodiments not shown in the drawings, the second mounting portion 12 and the elastic structure 40 may also be disposed on the cover member 15 .

[0064] In other embodiments not shown in the drawings, when both the mounting base 14 and the cover member 15 are provided with the second mounting portion 12, there are at least two first matching portions 322, there are at least two elastic structures 40, at least one first matching portion 322 is provided corresponding to the second mounting portion 12 provided on the mounting base 14, at least another first matching portion 322 is provided corresponding to the second mounting portion 12 provided on the cover member 15, and at least two elastic structures 40 are provided one-to-one with at least two second mounting portions 12. In this way, the above arrangement adopts the guiding design of the second mounting portion 12, the first matching portion 322 and the elastic structure 40 on both sides of the driving member 32 to further improve the movement stability of the driving member 32 (door panel 2).

[0065] like Figure 8 As shown, the driving member 32 includes: a plate-like structure 324, a first matching portion 322 and a second matching portion 323 are respectively located on two opposite sides of the plate-like structure 324, and a rack portion 321 is arranged on the plate surface of the plate-like structure 324 facing the gear member 31. In this way, the above arrangement makes the structure of the driving member 32 simpler, so as to reduce the processing difficulty and processing cost of the driving member 32.

[0066] Specifically, the rack portion 321 is formed by machining a plurality of tooth-shaped grooves on the plate surface of the plate-like structure 324 , thereby realizing an integrated design of the driving member 32 , thereby improving the overall structural strength of the driving member 32 and extending its service life.
