Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a transmission component limiting structure and an air conditioner. Background Art

[0002] The air outlet of the cabinet air conditioner is generally provided with a sliding door. When the air conditioner is working, the air outlet is opened by moving the sliding door. When the air conditioner stops working, the air outlet is closed by moving the sliding door, thereby shielding the air outlet.

[0003] The sliding door generally achieves relative movement with the air conditioner body through a transmission assembly. However, due to the presence of virtual positions and gaps in the transmission assembly, misalignment or steps often occur when the sliding door moves to the closed position. In addition, the transmission assembly is generally a plastic part. When the transmission assembly supports the movement of the sliding door for a long time, it is prone to wear, which can also cause the transmission assembly to loosen, resulting in misalignment or steps. Summary of the invention

[0004] The problem solved by the invention is that there is a misalignment or step phenomenon when the sliding door is closed.

[0005] In order to solve at least one aspect of the above problems, the present invention first provides a transmission component limiting structure, including an active member and a driven member driven by the driven member, the active member is installed on the air conditioner body, and the driven member is for installing the sliding door; the driven member is provided with a first limiting portion, and the air conditioner body is provided with a second limiting portion cooperating with the first limiting portion, and when the first limiting portion and the second limiting portion cooperate with each other and stop moving, the sliding door is limited in the inner and outer directions.

[0006] Compared with the prior art, the transmission assembly limiting structure described in the present invention sets a limiting structure between the driven part of the transmission assembly and the air conditioner body, and realizes the limitation of the sliding door in the inner and outer directions through the mutual cooperation of the first limiting part and the second limiting part, thereby ensuring that the relative position between the sliding door and the air conditioner body or the relative position between the two sliding doors is fixed, improving stability, and preventing misalignment or steps at the connection between the sliding door and the air conditioner body or the connection between the two sliding doors, thereby ensuring the overall aesthetics of the air conditioner.

[0007] Furthermore, the active member is a gear, and the driven member includes a rack meshing with the gear.

[0008] Compared with the prior art, the transmission assembly limiting structure of the present invention utilizes the meshing of the gear and the rack to realize the rotation of the sliding door, has a simple structure, is easy to process, and has high stability during the movement of the sliding door.

[0009] Further, the first limiting portion includes two stoppers spaced apart in the inner and outer directions, a groove is formed between the two stoppers, and the second limiting portion includes a protrusion matched with the groove.

[0010] Compared with the prior art, the transmission assembly limiting structure described in the present invention utilizes the groove and the protrusion to cooperate to achieve the limitation of the sliding door in the inner and outer directions. The cooperation structure is simple, easy to cooperate, and has high reliability, thereby ensuring that the sliding door will not be misplaced or shaken.

[0011] Further, the first limiting portion includes a circular hole, and the second limiting portion includes a cylinder matched with the circular hole. When the first limiting portion and the second limiting portion cooperate with each other, the outer wall of the cylinder abuts against the inner wall of the circular hole.

[0012] Compared with the prior art, the transmission assembly limiting structure described in the present invention utilizes the mutual cooperation between the cylinder and the circular hole to not only achieve the limiting of the sliding door in the inner and outer directions, but also achieves the limiting of the sliding door in the upper and lower directions, thereby preventing the sliding door from being misplaced in the inner and outer directions and the upper and lower directions.

[0013] Further, the first limiting portion is provided with a first guiding surface, and / or the second limiting portion is provided with a second guiding surface.

[0014] Compared with the prior art, the transmission assembly limiting structure described in the present invention provides guide surfaces on the first limiting portion and the second limiting portion, which can greatly improve the coordination efficiency between the first limiting portion and the second limiting portion, making the limiting of the sliding door more reliable and effective.

[0015] Furthermore, the follower is provided with a first limit portion at both ends in the moving direction of the sliding door, and the air conditioner body is provided with a second limit portion at both ends in the moving direction of the sliding door.

[0016] Compared with the prior art, the transmission assembly limiting structure described in the present invention has a first limiting portion at both ends of the driven member, which can ensure that the sliding door can be limited in the inward and outward directions when the sliding door is in the open state and the closed state, thereby maintaining the overall appearance of the air conditioner in various states.

[0017] Furthermore, the air conditioner body is provided with a T-shaped slot arranged along the moving direction of the sliding door, and the follower is slidably connected to the T-shaped slot.

[0018] Compared with the prior art, the transmission assembly limiting structure described in the present invention sets a T-slot on the air conditioner body, so that the movement of the driven member relative to the active member is more stable, and the position of the driven member in the inward and outward directions is limited during the sliding process of the driven member.

[0019] Furthermore, the outer wall of the follower is also connected to a baffle matched with the outer wall of the T-slot, and the cross section of the surface where the T-slot contacts the baffle or the outer wall of the follower is a wavy line in a direction perpendicular to the up and down direction.

[0020] Compared with the prior art, the transmission assembly limiting structure described in the present invention designs the T-slot and the baffle to be in line contact with each other, which effectively reduces the contact area between the follower and the air conditioner body during the sliding process, thereby greatly reducing the operating resistance and also making the assembly between the T-slot and the follower have a larger assembly tolerance rate.

[0021] Next, an air conditioner is provided, comprising an air conditioner body, a sliding door, and a plurality of transmission assembly limiting structures as described above for connecting the air conditioner body and the sliding door.

[0022] Furthermore, the sliding door includes a first sliding door and a second sliding door, and the transmission assembly limiting structure is respectively arranged at upper and lower ends of the first sliding door and the second sliding door.

[0023] Compared with the prior art, the air conditioner described in the present invention and the above-mentioned transmission component limiting structure have the same advantages over the prior art, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] 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.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "rear", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In this article, the X direction represents the moving direction of the sliding door, the positive X direction represents the direction of closing or opening the sliding door, the negative X direction represents the direction of opening or closing the sliding door, the positive Y direction represents the inner side of the sliding door, the negative Y direction represents the outer side of the sliding door, and the inner side of the sliding door is closer to the internal components of the air conditioner. The positive Z direction represents the upper side, that is, toward the top of the air conditioner, and the negative Z direction represents the lower side.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0042] Generally, cabinet air conditioners with sliding doors close and open the air outlet by moving the sliding doors, wherein the movement of the sliding doors is achieved by the transmission of the transmission assembly. However, since there are virtual positions and gaps in the transmission assembly, when the sliding door moves to the position to close the air outlet, the sliding door may move slightly inward or outward. Especially for cabinet air conditioners with double sliding doors, when the air outlet is closed, if one of the sliding doors moves inward and the other moves outward, there will be an obvious misalignment between the two sliding doors, creating a step, which seriously affects the overall appearance of the air conditioner.

[0043] Therefore, the present invention provides a transmission component limiting structure, combined with Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it includes an active member 1 and a driven member 2 driven by the active member 1, the active member 1 is installed on the air conditioner body 3, and the sliding door is hung on the driven member 2; the driven member 2 is provided with a first limiting portion 21, and the air conditioner body 3 is provided with a second limiting portion 31 cooperating with the first limiting portion 21, and when the first limiting portion 21 and the second limiting portion 31 cooperate with each other and stop moving, the sliding door is limited in the inner and outer directions.

[0044] Among them, the active part 1 is connected to the motor, and the motor provides driving force to drive the active part 1 to operate. The operation of the active part 1 drives the operation of the driven part 2. The positions of the driven part 2 and the sliding door are fixed to each other. When the driven part 2 is driven by the active part 1 and moves along the moving direction of the sliding door, the sliding door will also move synchronously with the driven part 2.

[0045] When the follower 2 stops running relative to the active member 1, due to the virtual position between the active member 1 and the follower 2, the follower 2 will shift in the inner and outer directions, thereby driving the sliding door to shift in the inner and outer directions. When the virtual position is large, the displacement distance of the sliding door inward or outward will also be large, which may cause the edge of the sliding door to be misaligned with other adjacent components, forming a step. Since the sliding door is an appearance part, in order not to affect the overall appearance of the sliding door, the transmission component limiting structure is arranged on the inner side of the sliding door, which has the effect of hiding the limiting structure. Specifically, a first limiting portion 21 is arranged at one end of the follower 2 in the moving direction of the sliding door. When the first limiting portion 21 cooperates with the second limiting portion 31 on the air conditioner body 3, the projections of the first limiting portion 21 and the second limiting portion 31 in the inner and outer directions both fall completely into the sliding door, thereby playing the role of hiding the transmission component limiting structure and ensuring the overall aesthetics of the air conditioner.

[0046] The air conditioner body 3 has a front panel, which is located above the air outlet, wherein the second limiter 31 can be set at the two side edges of the front panel, and the first limiter 21 of the follower 2 moves along the sliding door moving direction to the two side edges of the front panel until the first limiter 21 and the second limiter 31 are matched with each other and stop moving. Figure 8 As shown, the follower 2 is provided with a first limit block 23, and the air conditioner body 3 is provided with a second limit block 33. When the first limit portion 21 and the second limit portion 31 are matched with each other, the first limit block 23 also abuts against the second limit block 33 to realize the position of the sliding door in the moving direction of the sliding door.

[0047] In this embodiment, a limiting structure is provided between the driven member 2 of the transmission assembly and the air conditioner body 3. Through the cooperation of the first limiting portion 21 and the second limiting portion 31, the sliding door is limited in the inward and outward directions, thereby ensuring that the relative position between the sliding door and the air conditioner body 3 or the relative position between the two sliding doors is fixed, thereby improving stability and preventing misalignment or steps at the connection between the sliding door and the air conditioner body 3 or the connection between the two sliding doors, thereby ensuring the overall aesthetics of the air conditioner.

[0048] Preferably, combined Figure 5 and Fig.12 As shown, the active member 1 is a gear, and the driven member 2 includes a rack meshing with the gear.

[0049] Among them, the shape of the rack is consistent with the cross-section of the sliding door in the vertical direction, that is, when the cross-section of the sliding door in the vertical direction is straight, the rack is a straight rack, and when the cross-section of the sliding door in the vertical direction is arc-shaped, the rack is an arc-shaped rack.

[0050] The sliding door of the present embodiment is an arc-shaped sliding door, which can rotate around the air conditioner body 3 at a certain angle, but the rotation radius of the sliding door is generally large. When the sliding door needs to make a circular motion at a certain angle, the meshing of the gear and the arc-shaped rack is selected to easily realize the control of the output torque of the motor, so that the rotation of the sliding door can be realized with a smaller output torque, thereby reducing the performance requirements for the motor and reducing costs.

[0051] The rack has a certain width in the up and down directions, so when the rack is meshed with the gear, the contact area is large, making the operation of the sliding door more stable.

[0052] In this embodiment, the rotation of the sliding door is achieved by meshing the gear and the rack, which has a simple structure, is easy to process, and has high stability during the movement of the sliding door.

[0053] In some embodiments, in combination Figure 2 , Figure 5 , Figure 6 As shown, the first limiting portion 21 includes a groove 211, the second limiting portion 31 includes a protrusion 311 that cooperates with the groove 211, the first limiting portion 21 includes two blocks 212 spaced apart in the inner and outer directions, the groove 211 is formed between the two blocks 212, and when the first limiting portion 21 and the second limiting portion 31 cooperate with each other, the protrusion 311 is located between the two blocks 212.

[0054] Among them, the block 212 has a certain length in the up and down direction, so that the length of the groove 211 in the up and down direction is also longer, and the length of the protrusion 311 in the up and down direction shall not be less than the length of the groove 211 in the up and down direction, so that the groove 211 can be fully matched with the protrusion 311, ensuring the effectiveness of the cooperation between the protrusion 311 and the groove 211, thereby ensuring the accuracy of the sliding door position; the block 212 has a certain thickness in the inner and outer directions to ensure the anti-deformation strength of the block 212.

[0055] The stopper 212 is formed by extending the end of the follower 2 along the moving direction of the sliding door. The two stoppers 212 are parallel to each other in the inner and outer directions, and the protrusion 311 is perpendicular to the horizontal direction. When the protrusion 311 cooperates with the groove 211, it can directly limit the position of the follower 2; the inner and outer surfaces of the protrusion 311 are respectively in contact with the stopper 212, so that the mutual restriction position between the follower 2 and the air conditioner body 3 is more precise.

[0056] In addition, a protrusion may be provided on the first limiting portion 21 , and the second limiting portion 31 is provided with a groove matching with the protrusion.

[0057] In this embodiment, the groove 211 cooperates with the protrusion 311 to limit the sliding door in the inward and outward directions. The cooperation structure is simple, easy to cooperate, and has high reliability, thereby ensuring that the sliding door will not be misplaced or shaken.

[0058] In other embodiments, the first limiting portion 21 includes a circular hole, and the second limiting portion 31 includes a cylinder that cooperates with the circular hole. When the first limiting portion 21 and the second limiting portion 31 cooperate with each other, the outer wall of the cylinder abuts against the inner wall of the circular hole.

[0059] Among them, the circular hole is arranged at the end of the first limiting portion 21, the hole depth direction of the circular hole is consistent with the moving direction of the sliding door, and the cylinder is formed by extending the end of the second limiting portion 31 toward the moving direction of the sliding door; the number of circular holes can be multiple, and the number of cylinders is consistent with the number of circular holes. If there are multiple circular holes, it is preferred to arrange the circular holes at intervals in the up and down directions, so as to ensure the limitation of the position of the sliding door and make full use of the length of the follower 2 in the up and down directions.

[0060] In addition, a cylinder may be disposed on the first limiting portion 21 , and the second limiting portion 31 is provided with a round hole matching the cylinder.

[0061] In this embodiment, the cooperation between the cylinder and the circular hole not only achieves the limitation of the sliding door in the inner and outer directions, but also achieves the limitation of the sliding door in the upper and lower directions, thereby preventing the sliding door from being misplaced in the inner and outer directions and the upper and lower directions.

[0062] Preferably, combined Fig. 9 and Fig.10 As shown, the first limiting portion 21 is provided with a first guide surface 213, which is arranged at the ends of the inner and outer inner walls of the groove 211 or at the ends of the inner wall of the circular hole to facilitate the smooth insertion of the protrusion 311 or the cylinder into the groove 211 or the circular hole.

[0063] Alternatively, a second guide surface 312 is provided in the second limiting portion 31, and the second guide surface 312 is arranged on the ends of the inner and outer side walls of the protrusion 311 or on the ends of the outer wall of the cylinder to facilitate the groove 211 or the circular hole to be smoothly inserted outside the protrusion 311 or the cylinder.

[0064] In addition, when the first limiting portion 21 is provided with the first guide surface 213 and the second limiting portion 31 is also provided with the second guide surface 312, the mutual installation of the protrusion 311 and the groove 211 or the mutual installation of the cylinder and the circular hole is smoother and the installation reliability is higher.

[0065] In this embodiment, guiding surfaces are provided on the first limiting portion 21 and the second limiting portion 31, which can greatly improve the matching efficiency between the first limiting portion 21 and the second limiting portion 31, making the limiting of the sliding door more reliable and effective.

[0066] Preferably, combined Figures 9 to 11 As shown, both ends of the follower 2 in the moving direction of the sliding door are provided with a first limiting portion 21, and both ends of the air conditioner body 3 in the moving direction of the sliding door are provided with a second limiting portion 31.

[0067] Among them, the two first limiting portions 21 extend from the head and tail ends of the follower 2 respectively along two opposite directions of the moving direction of the sliding door. Correspondingly, a second limiting portion 31 is provided at the position corresponding to the two first limiting portions 21 on the air conditioner body 3 to ensure that the sliding door can be limited in the inward and outward directions when in the open position and the closed position.

[0068] In this embodiment, a first limiting portion 21 is provided at both ends of the follower 2, which can ensure that the sliding door can be limited in the inward and outward directions when the sliding door is in the open state and the closed state, thereby maintaining the overall appearance of the air conditioner in various states.

[0069] Preferably, the driven member 2 is detachably connected to the active member 1 .

[0070] Among them, the opening angles of the sliding doors of different air conditioners may be different, and the opening angle of the sliding door is determined by the length of movement of the driven member 2 relative to the active member 1; Figure 3 As shown, the length of the follower 2 in the moving direction of the sliding door is longer, so the sliding door can be opened at a larger angle; Figure 8 As shown, the shorter the length of the follower 2 in the moving direction of the sliding door is, the smaller the angle at which the sliding door can be opened is.

[0071] In this embodiment, the driven member 2 and the active member 1 are designed to be detachably connected to facilitate replacement of the driven member 2 of different length specifications, so that the air conditioner body 3 can be installed with sliding doors with different opening angles, thereby improving versatility.

[0072] Preferably, combined Figure 6 and Figure 8 As shown, the air conditioner body 3 is provided with a T-shaped slot 32 arranged along the moving direction of the sliding door, and the follower 2 is slidably connected to the T-shaped slot 32.

[0073] Among them, the T-slot 32 is closer to the outside than the active part 1, and the part of the driven part 2 that cooperates with the active part 1 (such as the rack) is located in the T-slot 32, which can limit the position of the driven part 2 in the inward and outward directions; a connecting block is protruded from the middle position of the outer wall of the driven part 2, which is connected to the sliding door through the connecting block, and the connecting block cooperates with the middle opening of the T-slot 32, which can limit the position of the driven part 2 in the up and down directions.

[0074] The two ends of the T-slot 32 in the moving direction of the sliding door are open, so that the driven member 2 can slide out of the T-slot, thereby realizing a detachable connection between the driven member 2 and the driving member 1 .

[0075] In this embodiment, a T-slot 32 is provided on the air conditioner body 3, so that the movement of the driven member 2 relative to the driving member 1 is more stable, and the position of the driven member 2 in the inner and outer directions is limited during the sliding process of the driven member 2.

[0076] Preferably, combined Figure 6 and Fig.12 As shown, the outer wall of the follower 2 is also connected to a baffle 22 that matches the outer wall of the T-slot 32, and the cross section of the surface where the T-slot 32 and the baffle 22 or the follower 2 contact each other is a wavy line in a perpendicular direction to the up and down direction.

[0077] The follower 2 has two baffles 22 with upper and lower openings respectively. Both ends of the baffles 22 in the moving direction of the sliding door are designed to be open, so that the distance between the follower 2 and the active member 1 moving relative to each other is long enough, thereby ensuring that the sliding door is opened at a certain angle.

[0078] A baffle plate 22 is provided on the follower 2 so that the baffle plate 22 cooperates with the T-slot 32 to achieve double limitation on the position of the follower 2 in the inner and outer directions, further ensuring that the sliding door will not shake inwards and outwards during movement.

[0079] In this embodiment, the T-slot 32 and the baffle 22 or the follower 2 are designed to be in line contact with each other, which effectively reduces the contact area between the follower 2 and the air conditioner body 3 during the sliding process, thereby greatly reducing the operating resistance and also making the assembly between the T-slot 32 and the follower 2 have a larger assembly tolerance rate.

[0080] The present invention also provides an air conditioner, such as Figure 1 As shown, it includes an air conditioner body 3, a sliding door, and a plurality of transmission assembly limiting structures as described above for connecting the air conditioner body 3 and the sliding door.

[0081] Preferably, the sliding door comprises a first sliding door and a second sliding door, and a transmission assembly limiting structure is respectively provided at the upper and lower ends of the first sliding door and the second sliding door. The two transmission assembly limiting structures at the upper end are symmetrically arranged, and the two transmission assembly limiting structures at the lower end are also symmetrically arranged; since the sliding door is relatively long in the up-down direction, the transmission assembly limiting structures are respectively arranged at the upper and lower ends, so that the movement of the sliding door can be ensured to be more stable, and when the sliding door moves into position, the position of the sliding door in the inner and outer directions can be limited at the upper and lower ends of the sliding door.

[0082] In this embodiment, a limiting structure is provided between the driven member 2 of the transmission assembly and the air conditioner body 3. Through the cooperation of the first limiting portion 21 and the second limiting portion 31, the sliding door is limited in the inward and outward directions, thereby ensuring that the relative position between the sliding door and the air conditioner body 3 or the relative position between the two sliding doors is fixed, thereby improving stability and preventing misalignment or steps at the connection between the sliding door and the air conditioner body 3 or the connection between the two sliding doors, thereby ensuring the overall aesthetics of the air conditioner.

[0083] 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 protection scope of the present invention shall be subject to the scope defined by the claims.
