Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a driving mechanism and an air conditioner having the same. Background Art

[0002] At present, a movable door panel component is generally installed at the air outlet of the indoor unit of the air conditioner to block or avoid the air outlet of the air conditioner so as to close or open the indoor unit of the air conditioner, and the driving mode of the panel door component is realized by relying on a motor and a gear rack mechanism, that is, the motor drives the gear structure to rotate to drive the rack mechanism to move, and the rack mechanism is connected to the door panel component to drive the door panel component to move. In order to improve the movement stability of the rack mechanism, a roller assembly and a guide sleeve are usually arranged on the rack mechanism. The roller assembly is mainly used to reduce the sliding resistance of the rack mechanism, and the guide sleeve is used to guide the movement direction of the rack mechanism during the movement of the rack mechanism.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

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

[0040] like Figures 1 to 11 As shown, the driving mechanism is arranged on the air conditioner body 1, and the driving mechanism includes: an installation shell 10, which has an installation cavity 11 and an opening 12 connected to the installation cavity 11; a sliding assembly 20, which is slidably arranged in the installation cavity 11, and the sliding assembly 20 includes a sliding structure 21 and a guide structure arranged on the sliding structure 21, at least a part of the sliding structure 21 extends out of the installation cavity 11 through the opening 12 and is connected to the door panel component 101 of the air conditioner body 1 to drive the door panel component 101 to move; a sliding groove arranged opposite to the guide structure is provided on the cavity wall of the installation cavity 11, and the sliding groove is arranged along the sliding assembly 20 extends in the sliding direction, and at least part of the guide structure is located in the slide groove, so as to guide the sliding direction of the sliding component 20 through the limit stop between the guide structure and the slide groove; wherein, the guide structure is at least two and includes 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, and along the height direction of the sliding component 20, 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.

[0041] Applying the technical solution of this embodiment, the driving mechanism is arranged on the air conditioner body 1 and includes a mounting shell 10 and a sliding assembly 20. The mounting shell 10 has a mounting cavity 11 and an opening 12 connected to the mounting cavity 11. The sliding assembly 20 is slidably arranged in the mounting cavity 11. At least a portion of the sliding structure 21 of the sliding assembly 20 extends out of the mounting cavity 11 through the opening 12 and is connected to the door panel component 101 of the air conditioner body 1 to drive the door panel component 101 to move. A sliding groove arranged opposite to the guide structure is provided on the cavity wall of the mounting cavity 11. The sliding groove extends along the sliding direction of the sliding assembly 20. At least a portion of the guide structure is located in the sliding groove to guide the sliding direction of the sliding assembly through a limit stop between the guide structure and the sliding groove. There are at least two guide structures including 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 in the slide slot and the length H2 of the second guide structure 23 in the slide slot satisfy: H2≥2H1. In this way, while guiding the movement direction of the sliding structure 21 through the limit stop between the guide structure and the slide slot to improve its movement stability, the second guide structure 23 is located below the sliding structure 21 to bear the force exerted by the door panel component 101 on the sliding structure 21. Its longer design ensures that it has a larger matching area with the slide slot, so as to enhance its guiding effect on the sliding structure 21 and preliminarily reduce the degree of posture deviation of the sliding structure 21. At the same time, through the cooperation between the first guide structure 22 and the second guide structure 23, a lever structure is approximately formed on the upper and lower sides of the sliding structure 21, that is, during the posture deviation of the sliding structure 21, the first guide structure 22 and the second guide structure 23 need to be offset accordingly, and the end offset distance of the second guide structure 23 with a longer length is larger. The numerical limit between the length H2 and the length H1 ensures that the second guide structure 23 can be quickly enough to stably limit the stop between the slide grooves to further reduce the posture deviation of the sliding structure 21, thereby avoiding structural interference, motion jitter, abnormal noise and other problems caused by the posture deviation of the sliding structure 21, thereby solving the problem of poor driving stability of the driving mechanism used to drive the door panel components to move in the prior art, thereby improving the user experience.

[0042] In this embodiment, the first guide structure 22 and the second guide structure 23 are arranged relative to each other in the height direction of the sliding assembly 20. Accordingly, the slide groove (first slide groove 13) arranged relative to the first guide structure 22 and the slide groove (second slide groove 14) arranged relative to the second guide structure 23 are arranged relative to each other, and the first slide groove 13 is located above the second slide 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, accordingly, the depth of the second slide groove 14 needs to be greater than twice the depth of the first slide groove 13.

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

[0045] Specifically, there is a certain friction force between the guide structure and the groove wall of the slide groove, and the friction force can provide rolling resistance during the sliding process of the sliding structure 21, thereby further improving the movement stability of the sliding structure 21.

[0046] Specifically, the depth of the slide groove and the length of the guide structure 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 sufficiently high anti-posture deflection effect.

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

[0048] In this embodiment, the sliding structure 21 is an arc-shaped structure to match its arc-shaped motion trajectory.

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

[0050] like Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig.11 As shown, the sliding assembly 20 further includes a roller structure, which is arranged on the sliding structure 21, and the outer peripheral surface of the roller structure abuts against the cavity wall of the installation cavity 11 and / or the groove bottom of the slide groove, and the roller structure rolls during the sliding process of the sliding assembly 20. In this way, the arrangement of the roller structure can reduce the friction between the sliding structure 21 and the cavity wall of the installation cavity 11 during the sliding process, so as to improve its movement smoothness.

[0051] like Figure 3As shown, the slide groove arranged opposite to the second guide structure 23 is the second slide groove 14, the sliding structure 21 is provided with a connecting arm 211 located below it, and 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 slide groove 14, and the outer peripheral surface of the second roller structure 25 abuts against the groove bottom of the second slide groove 14. In this way, the second roller structure 25 (with the lowest height) located in the second slide groove 14 can fully bear and reduce the force applied to the sliding structure 21 and the door panel component 101 on the sliding structure 21, so as to avoid excessive friction between the second guide structure 23 and the groove bottom of the slide groove, which may cause the sliding structure 21 to get stuck during the movement process, and further improve the sliding stability of the sliding structure 21.

[0052] Specifically, the bottom of the second slide groove 14 is actually the main force-bearing surface during the movement of the sliding structure 21, that is, the self-gravity of the sliding structure 21 and the force applied by the door panel component 101 to the sliding structure 21 are mainly applied to the bottom of the second slide groove 14. By providing a second roller structure 25 located in the second slide groove 14 and abutting against the bottom of the second slide groove 14, the above-mentioned gravity and force can be better borne and friction 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 bottom of the second slide groove 14.

[0053] In this embodiment, the end surface of the second guide structure 23 away from the sliding structure 21 is a mating surface, and there is an interference fit between the groove bottom and the mating surface of the slide groove arranged opposite to the second guide structure 23. In this way, the second guide structure 23 has a certain amount of interference fit after the initial assembly is completed, thereby improving the overall installation stability of the sliding assembly 20.

[0054] In this embodiment, the mating surface of the second guide structure 23 extends into the second slide groove 14 and is interference-fitted with the groove bottom of the second slide groove 14. In this way, the above arrangement can reduce the subsequent deformation of the second guide structure 23, so that the second guide structure 23 can also play the supporting and limiting functions, so as to avoid the second roller structure 25 being rigidly squeezed and unable to rotate, thereby avoiding the second roller structure 25 from being stuck, 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, it is possible to avoid excessive friction between the second guide structure 23 and the bottom of the second slide groove 14 while ensuring that the second roller structure 25 can rotate smoothly, further improving the sliding stability of the sliding structure 21.

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

[0057] like Figure 3 As shown, the plurality of roller structures further include a first roller structure 24. A mounting hole 212 is provided on the sliding structure 21. The mounting hole 212 is located on a 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 the first roller structure 24 reduces the sliding friction of the sliding structure 21, it actually forms a "lever"-like structure with the second roller structure 25 in the height direction of the sliding assembly 20 (the connecting arm 211 for installing the second roller structure 25 forms a lever arm). That is, if the door panel component 101 drives the sliding structure 21 to deviate 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 generate a reliable limit stop with the bottom of the second slide groove 14, so as to further reduce the degree of posture deviation of the sliding structure 21.

[0058] In this embodiment, there are two second roller structures 25, and the two second roller structures 25 are arranged on the sliding structure 21 at intervals along the sliding trajectory (arc trajectory) of the sliding structure 21. There are three first roller structures 24, and the three first roller structures 24 are also arranged on the sliding structure 21 at intervals along the sliding trajectory (arc trajectory) of the sliding structure 21. 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 gravity of the sliding structure 21 and the force applied by the door panel component 101 to the sliding structure 21 (including the gravity and locking force load of the door panel component 101), and the three first roller structures 24 are auxiliary rollers, which mainly cooperate with the second roller structures 25 to prevent the occurrence of posture deviation when the posture of the sliding structure 21 is about to deviate (that is, share the tilting force when the sliding structure 21 is deviated).

[0060] like Fig.11As shown, the roller structure includes a rotating shaft 26 and a roller 27 sleeved on the rotating shaft 26. A strip guide protrusion 28 is arranged on the outer peripheral surface of the roller 27. The strip guide protrusion 28 includes a first sub-strip segment 281 and a second sub-strip segment 282 connected to each other. The first sub-strip segment 281 and the second sub-strip segment 282 are arranged at an angle. In this way, the arrangement of the strip guide protrusion 28 can reduce the contact area between the roller 27 and the abutting surface, which can not only reduce its rolling resistance, but also reduce its rolling noise and improve its wear resistance. The arrangement of the first sub-strip segment 281 and the second sub-strip segment 282 makes the strip guide protrusion 28 form an arrow-shaped structure to further reduce the rolling resistance of the roller 27.

[0061] In the present embodiment, the first sub-strip segment 281 and the second sub-strip segment 282 are symmetrically arranged with respect to the center plane of the roller 27 .

[0062] In this embodiment, there are a plurality of strip-shaped guide protrusions 28 , and the plurality of strip-shaped guide protrusions 28 are arranged at intervals along the circumference of the roller 27 .

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

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

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

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

[0067] like Figure 2 , Figure 7 and Figure 8 As shown, a mounting protrusion 213 is provided on the sliding structure 21, and the guide structure is sleeved on the mounting protrusion 213. The outer peripheral surface of the guide structure is used to limit the stop between the groove wall of the slide groove. Among them, at least part of the guide structure is made of elastic material. In this way, the guide structure made of elastic material can adaptively undergo elastic deformation in the process of following the movement of the sliding structure 21 to improve the movement stability of the sliding structure 21. At the same time, the friction between the sliding structure 21 and the groove wall of the slide groove can also adapt to the change with the elastic deformation to provide adaptive damping (rolling resistance), further improving the movement stability of the sliding structure 21.

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

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

[0070] In this 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 bottom of the second slide groove 14 .

[0071] Optionally, in the two groove walls of the slide groove, the guide structure contacts the groove wall arranged near the opening 12, and has a clearance fit with the groove wall arranged far from the opening 12, and the clearance fit amount is 0.2mm-0.5mm. In this way, the above arrangement not only helps to further reduce the posture deflection degree of the sliding structure 21, but also can reduce its movement noise (no contact at the clearance fit, and the contact area is smaller).

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

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

[0074] like Figures 2 to 6 As shown, at least part of the rack structure 31 of the gear rack mechanism is made of a flexible material, and the mounting housing 10 includes a housing body 15 and at least two enclosure structures 16, and the housing body 15 has an installation cavity 11 and an opening 12. At least two enclosure structures 16 are arranged in the installation cavity 11 and are located on the side of the sliding assembly 20 away from the opening 12. At least two enclosure structures 16 are arranged opposite to each other and form a strip-shaped accommodation space 17 around the cavity wall of the installation cavity 11. Among them, the rack structure 31 can be movably arranged in the strip-shaped accommodation space 17, and each enclosure structure 16 is arranged parallel to the sliding track of the sliding assembly 20. The enclosure structure 16 guides the movement direction of the rack structure 31 by limiting the stop with the rack structure 31. In this way, the flexible rack structure 31 in this embodiment will maintain its own shape and guide its movement direction through the limit stop between the enclosure structure 16 and it during its movement. Compared with the traditional rigid rack, the setting of the flexible rack can minimize the rigid collision between the rack structure 31 and other structures, which not only helps to improve the movement stability of the rack structure 31, but also can reduce the processing accuracy requirements and movement noise of the rack structure 31.

[0075] Optionally, the rack structure 31 has a width of less than 10 mm, a thickness of less than 15 mm, and a length of more than 80 mm, so as to reduce the difficulty of the rack structure 31 undergoing flexible deformation and ensure that the rack structure 31 can undergo flexible deformation in a timely and stable manner.

[0076] In this embodiment, the shell body 15 includes a lower shell 151 and a cover body 152 covered on the lower shell 151. The installation cavity 11 is formed between the lower shell 151 and the cover body 152. The enclosure structure 16 can be set on the lower shell 151 or on the cover body 152.

[0077] Specifically, since the motion trajectory of the rack structure 31 is actually an arc trajectory, if the rack structure 31 is rigid, it is very easy to produce a rigid collision and scratch with the enclosure structure 16 with a large noise due to its own processing accuracy, which not only affects the user experience, but also causes the rack structure 31 to be easily worn. If the rack structure 31 is set to be flexible, it can spontaneously deform flexibly through the limit stop between it and the enclosure structure 16 during the movement, so that the overall movement process of the rack structure 31 is smoother, the movement amount is smaller, and it is no longer limited by the influence of processing accuracy.

[0078] like Figure 4 and Figure 6 As shown, the gear structure 32 of the rack and pinion mechanism is rotatably arranged on a side of the rack structure 31 away from the sliding assembly 20, and a first strip-shaped avoidance opening 161 is arranged on the enclosure structure 16 arranged close to the sliding assembly 20 relative to the gear structure 32, and at least part of the connecting member 29 for connecting the rack structure 31 and the sliding structure 21 is located in the first strip-shaped avoidance opening 161. A second strip-shaped avoidance opening 162 is arranged on the enclosure structure 16 arranged away from the sliding assembly 20 relative to the gear structure 32, and the gear structure 32 is meshed with the rack structure 31 through the second strip-shaped avoidance opening 162. In this way, the setting of the first strip-shaped avoidance opening 161 can avoid the connecting member 29 to ensure that the rack structure 31 can drive the connecting member 29 to move, so as to drive the sliding structure 21 to move, and the setting of the second strip-shaped avoidance opening 162 realizes the meshing between the gear structure 32 and the rack structure 31.

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

[0080] like Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, a first limiting protrusion 311 is provided on the side of the rack structure 31 away from the gear structure 32, and the first limiting protrusion 311 is used to limit and stop with the enclosure structure 16. A second limiting protrusion 171 is provided on the bottom wall of the strip-shaped accommodation space 17, and the second limiting protrusion 171 is used to limit and stop with the lower surface of the rack structure 31; and / or, a third limiting protrusion 172 is provided on the top wall of the strip-shaped accommodation space 17, and the third limiting protrusion 172 is used to limit and stop with the upper surface of the rack structure 31. In this way, the provision 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 enclosure structure 16 and the cavity wall of the installation cavity 11, so as to further reduce the noise generated by the rack structure 31 during the movement and improve the user experience.

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

[0082] Optionally, there is a clearance fit between the enclosure structure 16 close to the opening 12 and the first limiting protrusion 311, and the clearance fit amount is 0.2 mm to 0.5 mm.

[0083] In this embodiment, the clearance between the enclosure structure 16 close to the opening 12 and the first limiting protrusion 311 is 0.2 mm.

[0084] In this embodiment, there is a clearance fit between the enclosure structure 16 away from the opening 12 and the tooth top surface of the rack structure 31 , and the clearance fit amount is 0.5 mm.

[0085] In this 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 trajectory of the sliding structure 21 .

[0087] In this embodiment, there is a clearance fit between the upper surface of the rack structure 31 and the third limiting protrusion 172 , and the clearance fit amount is 0.3 mm.

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

[0089] like Fig.12As shown, this embodiment also provides an air conditioner, which includes an air conditioner body 1 and a driving mechanism, wherein the driving mechanism is arranged on the air conditioner body 1 and is drivingly connected to a door panel component 101 of the air conditioner body 1, the housing of the air conditioner body 1 has an air outlet, and the driving mechanism is used to drive the door panel component 101 to move so that the door panel component 101 blocks or avoids the air outlet. The driving mechanism is the above-mentioned driving mechanism.

[0090] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0091] The driving mechanism is arranged on the air conditioner body and includes a mounting shell and a sliding assembly. The mounting shell has a mounting cavity and an opening connected to the mounting cavity. The sliding assembly can be slidably arranged in the mounting cavity. At least part of the sliding structure of the sliding assembly extends out of the mounting cavity through the opening and is connected to the door panel component of the air conditioner body to drive the door panel component to move. The cavity wall of the mounting cavity has a slide groove arranged opposite to the guide structure. The slide groove extends along the sliding direction of the sliding assembly. At least part of the guide structure is located in the slide groove to guide the sliding direction of the sliding assembly through the limit stop between the guide structure and the slide groove. Among them, there are at least two guide structures and include a first guide structure and a second guide structure. The first guide structure is located above the sliding structure, and the second guide structure is located below the sliding structure. Along the height direction of the sliding assembly, the length H1 of the first guide structure in the slide groove and the length H2 of the second guide structure in the slide groove satisfy: H2≥2H1. In this way, while guiding the movement direction of the sliding structure through the limit stop between the guide structure and the slide slot to improve its movement stability, the second guide structure is located below the sliding structure to carry the force exerted by the door panel component on the sliding structure. Its longer design ensures that it has a larger matching area with the slide slot, so as to enhance its guiding effect on the sliding structure and preliminarily reduce the degree of posture deflection of the sliding structure. At the same time, through the mutual cooperation of the first guide structure and the second guide structure, a lever structure is approximately formed on the upper and lower sides of the sliding structure, that is, in the process of posture deflection of the sliding structure, the first guide structure and the second guide structure need to be offset accordingly, and the end offset distance of the second guide structure with a longer length is larger. The numerical limit between the length H2 and the length H1 ensures that the second guide structure can be stably limited and stopped between the slide slot quickly enough to further reduce the degree of posture deflection of the sliding structure, thereby avoiding structural interference, movement jitter, abnormal noise and other problems caused by the posture deflection of the sliding structure, thereby solving the problem of poor driving stability of the driving mechanism used to drive the door panel component to move in the prior art and improving the user experience.
