[0037] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0039] In order to solve the problem of poor driving stability of the driving mechanism for driving the door plate component to move in the prior art, the present application provides a driving mechanism and an air conditioner having the same.

[0040] As shown in Figures 1 to 11 The driving mechanism is arranged on the air conditioner body 1, and the driving mechanism comprises: a mounting shell 10 having a mounting cavity 11 and an opening 12 communicating with the mounting cavity 11; a sliding assembly 20 slidably arranged in the mounting cavity 11, the sliding assembly 20 comprising a sliding structure 21 and a guide structure arranged on the sliding structure 21, at least part of the sliding structure 21 extending out of the mounting cavity 11 through the opening 12 and being connected with a door plate component 101 of the air conditioner body 1 to drive the door plate component 101 to move; the cavity wall of the mounting cavity 11 has a sliding groove arranged opposite to the guide structure, the sliding groove extending along the sliding direction of the sliding assembly 20, and at least part of the guide structure being located in the sliding groove to guide the sliding direction of the sliding assembly 20 through the limiting stop between the guide structure and the sliding groove; wherein the guide structure is at least two and comprises a first guide structure 22 and a second guide structure 23, the first guide structure 22 being located above the sliding structure 21, and the second guide structure 23 being located below the sliding structure 21, the length H1 of the first guide structure 22 located in the sliding groove and the length H2 of the second guide structure 23 located in the sliding groove satisfying: H2≥2H1 along the height direction of the sliding assembly 20.

[0041] According to the technical scheme, the driving mechanism is arranged on the air conditioner main body 1 and comprises a mounting shell 10 and a sliding assembly 20. The mounting shell 10 has a mounting cavity 11 and an opening 12 communicating with the mounting cavity 11. The sliding assembly 20 is slidably arranged in the mounting cavity 11. At least part of a sliding structure 21 of the sliding assembly 20 extends out of the mounting cavity 11 through the opening 12 and is connected with a door plate component 101 of the air conditioner main body 1 to drive the door plate component 101 to move. The cavity wall of the mounting cavity 11 is provided with a sliding groove opposite to the guide structure and extending along the sliding direction of the sliding assembly 20. At least part of the guide structure is located in the sliding groove to guide the sliding direction of the sliding assembly through the limiting stop between the guide structure and the sliding groove. The guide structure is at least two and comprises a first guide structure 22 and a second guide structure 23. The first guide structure 22 is located above the sliding structure 21, and the second guide structure 23 is located below the sliding structure 21 along the height direction of the sliding assembly 20. The length H1 of the first guide structure 22 located in the sliding groove and the length H2 of the second guide structure 23 located in the sliding groove satisfy H2≥2H1. In this way, the movement direction of the sliding structure 21 is guided through the limiting stop between the guide structure and the sliding groove to improve the movement stability. At the same time, the second guide structure 23 is used as the guide structure below the sliding structure 21 to bear the force applied by the door plate component 101 on the sliding structure 21. The longer length ensures that the second guide structure 23 has a larger matching area with the sliding groove to improve the guiding effect on the sliding structure 21 and preliminarily reduce the attitude deflection of the sliding structure 21. At the same time, the first guide structure 22 and the second guide structure 23 form a lever structure on the upper and lower sides of the sliding structure 21. In the attitude deflection process of the sliding structure 21, the first guide structure 22 and the second guide structure 23 need to be offset correspondingly. The end of the second guide structure 23 with a longer length has a larger offset distance. The numerical limitation between the length H2 and the length H1 ensures that the second guide structure 23 can be stably limited and stopped between the sliding groove to further reduce the attitude deflection of the sliding structure 21, thereby avoiding the problems of structure interference, movement jitter and abnormal sound caused by the attitude deflection of the sliding structure 21, and improving the user experience.

[0042] In the embodiment, the first guide structure 22 and the second guide structure 23 are arranged opposite to each other along the height direction of the sliding assembly 20. Correspondingly, the sliding groove opposite to the first guide structure 22 (the first sliding groove 13) and the sliding groove opposite to the second guide structure 23 (the second sliding groove 14) are arranged opposite to each other, and the first sliding groove 13 is located above the second sliding groove 14.

[0043] Specifically, since the length H1 of the first guide structure 22 in the slide groove and the length H2 of the second guide structure 23 in the slide groove satisfy H2≥2H1, the depth of the second slide groove 14 is greater than twice the depth of the first slide groove 13.

[0044] In the embodiment, the depth of the first slide groove 13 is 9.4mm, and the depth of the second slide groove 14 is 20.3mm.

[0045] Specifically, the guide structure and the groove wall of the slide groove have a certain friction force, which can provide rolling resistance during the sliding of the sliding structure 21, further improving the motion stability of the sliding structure 21.

[0046] Specifically, the slide groove depth and the guide structure length are determined by the inclined downward force applied by the door panel component 101 on the sliding structure 21, thereby ensuring that the cooperation between the second guide structure 23 and the first guide structure 22 can produce a high enough anti-posture deflection effect.

[0047] In the embodiment, the motion trajectory of the sliding assembly 20 is in the shape of an arc, so as to match the motion direction of the door panel component 101 (the structure of the air conditioner main body 1).

[0048] In the embodiment, the sliding structure 21 is in an arc shape, so as to match the arc-shaped motion trajectory thereof.

[0049] It should be noted that the motion trajectory of the sliding assembly 20 can be adjusted according to actual processing needs and the structure of the air conditioner main body 1.

[0050] As shown in Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 11 , the sliding assembly 20 further comprises a roller structure, which is arranged on the sliding structure 21, the outer periphery of the roller structure abuts against the cavity wall of the mounting cavity 11 and / or the groove bottom of the slide groove, and the roller structure rolls during the sliding of the sliding assembly 20. In this way, the arrangement of the roller structure can reduce the friction force between the sliding structure 21 and the cavity wall of the mounting cavity 11 during the sliding, so as to improve the smoothness of the motion thereof.

[0051] As shown in Figure 3As shown, the sliding groove opposite to the second guide structure 23 is a second sliding groove 14, the sliding structure 21 is provided with a connecting arm 211 below it, the roller structure is multiple and includes a second roller structure 25, and the second roller structure 25 is rotatably arranged on the connecting arm 211. Among them, the second roller structure 25 is located in the second sliding groove 14, and the outer circumferential surface of the second roller structure 25 abuts against the groove bottom of the second sliding groove 14. In this way, the second roller structure 25 (with the lowest height) located in the second sliding groove 14 can fully bear and reduce the friction between the second guide structure 23 and the groove bottom, so as to avoid the problem that the movement of the sliding structure 21 is stuck due to excessive friction between the second guide structure 23 and the groove bottom, and further improve the sliding stability of the sliding structure 21.

[0052] Specifically, the groove bottom of the second sliding groove 14 is actually the main force bearing surface during the movement of the sliding structure 21, that is, the gravity of the sliding structure 21 and the force applied by the door plate component 101 on the sliding structure 21 are mainly applied to the groove bottom of the second sliding groove 14. By arranging the second roller structure 25 located in the second sliding groove 14 and abutting against the groove bottom of the second sliding groove 14, the above gravity and force can be better borne and reduced, so as to improve the sliding stability of the sliding structure 21 while avoiding excessive friction between the second guide structure 23 and the groove bottom of the second sliding groove 14.

[0053] In this embodiment, the end surface of the second guide structure 23 away from the sliding structure 21 is a matching surface, and the groove bottom of the sliding groove opposite to the second guide structure 23 and the matching surface are in interference fit. In this way, the second guide structure 23 has a certain interference fit after initial assembly, so as to improve the overall installation stability of the sliding assembly 20.

[0054] In this embodiment, the matching surface of the second guide structure 23 protrudes into the second sliding groove 14 and is in interference fit with the groove bottom of the second sliding groove 14. In this way, the above arrangement can reduce the subsequent deformation amount of the second guide structure 23, so that the second guide structure 23 can also play a supporting and limiting function, so as to avoid the second roller structure 25 being hard pressed and unable to rotate, thereby avoiding the jamming phenomenon of the second roller structure 25, and further improving the sliding stability of the sliding structure 21.

[0055] Specifically, through the mutual cooperation between the second guide structure 23 and the second roller structure 25, the second roller structure 25 can be ensured to rotate smoothly while avoiding excessive friction between the second guide structure 23 and the groove bottom of the second sliding groove 14, and further improving the sliding stability of the sliding structure 21.

[0056] In this embodiment, the interference fit between the end face of the second guide structure 23 away from the sliding structure 21 and the bottom of the second groove 14 is 0.2 mm.

[0057] like Figure 3 As shown, the multiple roller structures also include a first roller structure 24. The sliding structure 21 is provided with a mounting hole 212, which is located on the side of the guide structure away from the opening 12. The first roller structure 24 is rotatably disposed in the mounting hole 212. At least a portion of the first roller structure 24 is located outside the mounting hole 212 to contact the cavity wall of the mounting cavity 11. In this way, while reducing the sliding friction of the sliding structure 21, the first roller structure 24 and the second roller structure 25 also form a lever-like structure in the height direction of the sliding assembly 20 (the connecting arm 211 for mounting the second roller structure 25 forms a lever arm). That is, if the door panel component 101 causes the sliding structure 21 to tilt in posture, the second roller structure 25 and the first roller structure 24 will respectively undergo corresponding offset movements. Under the action of the connecting arm 211, the offset of the second roller structure 25 is greater, and it can more quickly and reliably stop with the bottom of the second slide groove 14 to further reduce the degree of tilt of the sliding structure 21.

[0058] In this embodiment, there are two second roller structures 25, which are spaced apart on the sliding structure 21 along the sliding trajectory (arc-shaped trajectory). There are three first roller structures 24, which are also spaced apart on the sliding structure 21 along the sliding trajectory (arc-shaped trajectory). The three first roller structures 24 are located on the side of the two second roller structures 25 away from the opening 12.

[0059] Specifically, the two second roller structures 25 are load-bearing rollers, which are mainly used to bear the weight of the sliding structure 21 and the force exerted on the sliding structure 21 by the door panel component 101 (including the weight of the door panel component 101 and the locking force load), while the three first roller structures 24 are auxiliary rollers, which are mainly used to cooperate with the second roller structures 25 to prevent the occurrence of attitude deviation when the attitude of the sliding structure 21 is about to deviate (i.e., to share the tilting force when the attitude of the sliding structure 21 deviates).

[0060] like Figure 11As shown, the roller structure comprises a rotating shaft 26 and a roller 27 sleeved on the rotating shaft 26, and a strip-shaped guide protrusion 28 is arranged on the outer circumferential surface of the roller 27. The strip-shaped guide protrusion 28 comprises a first sub-strip-shaped segment 281 and a second sub-strip-shaped segment 282 connected with each other, and the first sub-strip-shaped segment 281 and the second sub-strip-shaped segment 282 are arranged at an included angle. In this way, the arrangement of the strip-shaped guide protrusion 28 can reduce the contact area between the roller 27 and the abutting surface, thereby reducing the rolling resistance and the rolling noise and improving the wear resistance.

[0061] In the embodiment, the first sub-strip-shaped segment 281 and the second sub-strip-shaped segment 282 are symmetrically arranged about the center of the roller 27.

[0062] In the embodiment, the strip-shaped guide protrusion 28 is provided in a plurality of forms, and the plurality of strip-shaped guide protrusions 28 are arranged at intervals along the circumference of the roller 27.

[0063] Optionally, the interval between the two adjacent strip-shaped guide protrusions 28 is 0.2mm-0.5mm.

[0064] In the embodiment, the interval between the two adjacent strip-shaped guide protrusions 28 is 0.4mm.

[0065] Optionally, the height of the strip-shaped guide protrusion 28 is 0.2mm-0.5mm.

[0066] In the embodiment, the height of the strip-shaped guide protrusion 28 is 0.2mm.

[0067] As shown in Figure 2 , Figure 7 and Figure 8 , the sliding structure 21 is provided with a mounting protrusion 213, and a guide structure is sleeved on the mounting protrusion 213, and the outer circumferential surface of the guide structure is used for limiting and stopping between the groove wall of the sliding groove. At least part of the guide structure is made of elastic material. In this way, the guide structure made of elastic material can adaptively elastically deform during the movement of the sliding structure 21, so as to improve the movement stability of the sliding structure 21. At the same time, the friction between the sliding structure 21 and the sliding groove wall can also adaptively change with the elastic deformation, so as to provide adaptive damping (rolling resistance), further improving the movement stability of the sliding structure 21.

[0068] In the embodiment, the guide structure is a rubber piece.

[0069] In the embodiment, the first guide structure 22 is a cylindrical structure, which is sleeved on the corresponding mounting protrusion 213.

[0070] In the embodiment, the second guide structure 23 is a cap-shaped structure with one end blocked, which is sleeved on the corresponding mounting protrusion 213, and the blocked end is used to abut against the groove bottom of the second sliding groove 14.

[0071] Optionally, in the two groove walls of the sliding groove, the guide structure is in contact with the groove wall close to the opening 12, and a gap is formed between the guide structure and the groove wall away from the opening 12, and the gap is 0.2mm-0.5mm. In this way, the above-mentioned arrangement not only helps to further reduce the attitude deflection of the sliding structure 21, but also reduces the movement noise (no contact at the gap, smaller contact area).

[0072] In the embodiment, the gap between the guide structure and the groove wall away from the opening 12 is 0.3mm.

[0073] As shown in Figures 2 to 6 , the driving mechanism further comprises a driving assembly 30, which is arranged in the mounting cavity 11. The driving assembly 30 comprises a driving member and a gear and rack mechanism. The driving member is drivingly connected with the sliding structure 21 through the gear and rack mechanism, so as to drive the sliding structure 21 to slide. In this way, the above-mentioned arrangement realizes the automatic sliding action of the sliding structure 21 through the cooperation between the driving member and the gear and rack mechanism, and realizes the automatic driving function of the driving mechanism.

[0074] As shown in Figures 2 to 6 , at least part of the rack structure 31 of the gear and rack mechanism is made of flexible material. The mounting shell 10 comprises a shell body 15 and at least two surrounding plate structures 16. The shell body 15 has a mounting cavity 11 and an opening 12. The at least two surrounding plate structures 16 are arranged in the mounting cavity 11 and located away from the opening 12 of the sliding assembly 20. The at least two surrounding plate structures 16 are oppositely arranged and surround the rack structure 31 to form a strip-shaped accommodating space 17. The rack structure 31 is movably arranged in the strip-shaped accommodating space 17. Each surrounding plate structure 16 is arranged in parallel with the sliding track of the sliding assembly 20. The surrounding plate structure 16 is limited and stopped by the rack structure 31, so as to guide the movement direction of the rack structure 31. In this way, the flexible rack structure 31 in the embodiment can maintain its own shape and guide its movement direction through the limiting and stopping between the surrounding plate structure 16 and the rack structure 31 during the movement process. Compared with the traditional rigid rack, the flexible rack can reduce the rigid collision between the rack structure 31 and other structures to the greatest extent, which not only helps to improve the movement stability of the rack structure 31, but also reduces the processing precision requirement and movement noise of the rack structure 31.

[0075] Optionally, the width of the rack structure 31 is less than or equal to 10 mm, the thickness is less than or equal to 15 mm, and the length is greater than or equal to 80 mm, so as to reduce the difficulty of flexible deformation of the rack structure 31 and ensure that the rack structure 31 can timely and stably deform flexibly.

[0076] In the embodiment, the shell body 15 includes a lower shell 151 and a cover body 152 arranged on the lower shell 151, and an installation cavity 11 is formed around the lower shell 151 and the cover body 152. The surrounding plate structure 16 can be arranged on the lower shell 151 or the cover body 152.

[0077] Specifically, since the movement track of the rack structure 31 is actually an arc track, if the rack structure 31 is rigid, it is easy to cause a rigid collision or scratch with the surrounding plate structure 16 due to the machining precision of the rack structure 31, which not only affects the user experience, but also causes the rack structure 31 to be easily worn. By setting the rack structure 31 to be flexible, the rack structure 31 can spontaneously deform flexibly through the limiting and stopping between the rack structure 31 and the surrounding plate structure 16 during movement, so that the overall movement of the rack structure 31 is more stable and the amount of movement is smaller, and is no longer affected by the machining precision.

[0078] As shown in Figure 4 and Figure 6 , the gear structure 32 of the gear and rack mechanism is rotatably arranged on the side of the rack structure 31 away from the sliding assembly 20.

In this way, the first strip-shaped avoiding opening 161 can avoid the connecting piece 29, so as to ensure that the rack structure 31 can drive the connecting piece 29 to move and drive the sliding structure 21 to move, and the second strip-shaped avoiding opening 162 realizes the engagement between the gear structure 32 and the rack structure 31.

[0079] In the embodiment, the side of the rack structure 31 away from the gear structure 32 is provided with a connecting structure located in the first strip-shaped avoiding opening 161, the connecting structure is provided with a through hole, and the connecting piece 29 includes two pins and a connecting plate. One pin is inserted into the through hole of the connecting structure and the connecting plate, and the other pin is inserted into the connecting plate and the sliding structure 21, so as to realize the connection between the rack structure 31 and the sliding structure 21.

In this way, the arrangement of the first limiting protrusion 311, the second limiting protrusion 171 and the third limiting protrusion 172 can reduce the contact area between the rack structure 31 and the coaming structure 16 and the cavity wall of the mounting cavity 11, so as to further reduce the noise generated by the rack structure 31 during movement, and improve the user experience.

[0081] In the embodiment, the first limiting protrusion 311 is a strip-shaped protruding rib arranged on the non-tooth-shaped side of the rack structure 31.

[0082] Optionally, the coaming structure 16 near the opening 12 is gap-fitted with the first limiting protrusion 311, and the gap-fitting amount is 0.2mm-0.5mm.

[0083] In the embodiment, the gap-fitting amount between the coaming structure 16 near the opening 12 and the first limiting protrusion 311 is 0.2mm.

[0084] In the embodiment, the coaming structure 16 away from the opening 12 is gap-fitted with the tooth top surface of the rack structure 31, and the gap-fitting amount is 0.5mm.

[0085] In the embodiment, the lower surface of the rack structure 31 is in contact with the second limiting protrusion 171.

[0086] Optionally, the second limiting protrusion 171 is a strip-shaped protrusion parallel to the movement track of the sliding structure 21.

[0087] In the embodiment, the upper surface of the rack structure 31 is gap-fitted with the third limiting protrusion 172, and the gap-fitting amount is 0.3mm.

[0088] Optionally, the third limiting protrusion 172 is a strip-shaped protrusion parallel to the movement track of the sliding structure 21.
