Technical Field
[0001] This invention relates to the field of air conditioning technology, and more specifically, to a sliding door assembly and an air conditioner. Background Technology
[0002] Currently, many air conditioner indoor units are equipped with a sliding door assembly at the air outlet. The sliding door assembly includes a sliding door and a drive mechanism that drives the sliding door to rotate around the circumference of the air conditioner indoor unit. When the air conditioner is idle, the drive mechanism can drive the sliding door to slide to the air outlet to block the air outlet; after the air conditioner is turned on, the drive mechanism can drive the sliding door to slide back in the opposite direction to expose the air outlet.
[0003] However, in existing air conditioner indoor units, the positioning and installation of sliding doors are all on the moving parts of the drive mechanism, which causes the entire weight of the sliding door to be borne by the moving parts. The moving parts are subjected to excessive force during movement, which can easily lead to unstable movement of the sliding door.
[0004] In summary, overcoming the aforementioned defects of the sliding door assembly in existing air conditioning indoor units is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0009] In the sliding door assembly provided by this invention, the weight of the sliding door can be directly applied to the drive box through the load-bearing body, and then transferred to the air outlet frame or other support structure by the drive box. At the same time, the moving parts connected to the sliding door are also supported by the sliding door, and the weight of the moving parts can be transferred to the air outlet frame through the sliding door and the drive box. Meanwhile, other components of the drive mechanism are directly supported by the drive box. In this way, the positions where the moving parts of the drive mechanism cooperate with other components do not need to bear the weight of the moving parts and the sliding door, but only need to bear the transmission force, which reduces the force borne by the moving parts. As a result, the moving parts of the drive mechanism can operate more stably, and the sliding door driven by the moving parts can slide more stably.

[0015] The beneficial effect is that the clearance opening will not affect the meshing of the gear and rack, which facilitates the stable transmission of power between the gear and rack, thereby ensuring the stable sliding of the sliding door.
[0016] Preferably, as one possible implementation, the sidewalls of the recess are arranged in a closed annular structure.
[0017] The beneficial effect is that it makes it easier to ensure the strength of the rack, and thus ensures the overall strength of the rack and the sliding door, reduces the probability of deformation, and extends the service life.
[0018] Preferably, as one possible implementation, the connecting portion has a first side plate and a second side plate that are angled together and connected to each other, the side of the first side plate facing away from the second side plate is connected to the toothed portion, and the second side plate is disposed opposite to the toothed portion.
[0019] The beneficial effect is that it can improve the structural strength of the connection, and thus improve the structural strength of the rack.
[0020] Preferably, as one possible implementation, the first side plate and the second side plate are transitioned by a rounded corner, and / or the clearance opening intersects with the apex corner of the connecting portion.
[0021] The beneficial effect is that it can alleviate the stress concentration problem at the junction of the first and second side plates, reduce the probability of fracture at the junction of the first and second side plates of the connection, and improve the structural stability of the rack.

The first straight side is close to the tooth, the second straight side is away from the tooth, and the two curved sides are arranged opposite to each other. The two ends of each curved side are respectively connected to the first straight side and the second straight side, and the two curved sides intersect with the apex corner of the connecting part.
[0023] The beneficial effect is that the portion of the clearance opening located on the second side plate can avoid the connection structure between the load-bearing body and the sliding door; in addition, the clearance opening is set in this way to improve the structural strength and facilitate the improvement of injection molding flow, thereby obtaining higher structural strength.
[0024] Preferably, as one possible implementation, the load-bearing body is a bearing, and the bearing is in rolling contact with the drive box.
[0025] The beneficial effect is that, while avoiding the load-bearing parts, the structural shape of the clearance opening is simplified as much as possible, reducing the difficulty of processing.
[0026] The present invention also provides an air conditioner, which includes an air outlet frame and the aforementioned sliding door assembly, wherein the drive box is mounted on the air outlet frame.
[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0040] See Figures 1-3 This embodiment provides a sliding door assembly, which includes a drive box 100, a sliding door 200 and a drive mechanism. The drive mechanism is installed in the drive box 100, and the moving parts of the drive mechanism are connected to the sliding door 200 in a transmission manner. A load-bearing body 300 is installed on the sliding door 200, and the bottom of the load-bearing body 300 is in contact with the drive box 100.
[0041] In the sliding door assembly provided in this embodiment, the weight of the sliding door 200 can be directly applied to the drive box 100 through the load-bearing body 300, and then transferred to the air outlet frame or other support structure by the drive box 100. At the same time, the moving parts connected to the sliding door 200 are also supported by the sliding door 200. The weight of the moving parts can be transferred to the air outlet frame through the sliding door 200 and the drive box 100, while other components of the drive mechanism are directly supported by the drive box 100. In this way, the position where the moving parts of the drive mechanism cooperate with other components does not need to bear the weight of the moving parts and the sliding door 200, but only needs to bear the transmission force, which reduces the force borne by the moving parts. As a result, the moving parts of the drive mechanism can operate more stably, and the sliding door 200 driven by the moving parts can slide more stably.
[0042] In the specific structure of the aforementioned drive mechanism, a rotary power source, a gear, and a rack 400 can be provided. The rotary power source is installed on the drive box 100, and the output end of the rotary power source is connected to the gear transmission. In this way, the weight of the rotary power source and the gear can be directly applied to the drive box 100. The gear meshes with the rack 400, and the rack 400 is fixedly connected to the sliding door 200. When the rotary power source drives the gear to rotate, the rack 400 can move along its arc, thereby driving the sliding door 200 to slide synchronously with it. That is, the rack 400 is the moving part of the drive mechanism, and the weight of the rack 400 is applied to the sliding door 200. At the meshing position of the rack 400 and the gear, the rack 400 does not need to bear the weight of the rack 400 and the sliding door 200, but only needs to bear the transmission force, which reduces the force borne by the rack 400. Thus, the operational stability of the rack 400 can be improved, thereby improving the sliding stability of the sliding door 200.
[0043] Specifically, see Figure 2 An offset opening 410 is provided on the rack 400 so that the load-bearing body 300 is placed within the offset opening 410. The offset opening 410 makes way for the load-bearing body 300, allowing the load-bearing body 300 to contact the drive box 100 within the area where the rack 400 is located. This shortens the distance between the center of gravity of the load-bearing body 300 and the center of gravity of the rack 400, as well as the distance between the center of gravity of the load-bearing body 300 and the sliding door 200, thereby improving the operational stability of the rack 400 and the sliding stability of the sliding door 200.
[0044] Specifically, see Figure 3 The aforementioned rack 400 includes a toothed portion 420 and a connecting portion 430. The toothed portion 420 meshes with a gear, and the connecting portion 430 is connected to the sliding door 200. An offset opening 410 is provided on the connecting portion 430. Thus, the presence of the offset opening 410 will not affect the meshing of the gear and the rack 400, which facilitates the stable transmission of power between the gear and the rack 400, thereby ensuring the stable sliding of the sliding door 200.
[0045] Preferably, the sidewalls of the recess 410 can form a closed ring structure, which helps to ensure the strength of the rack 400, and thus ensures the overall strength of the rack 400 and the sliding door 200, reduces the probability of deformation, and extends the service life.
[0046] Specifically, the connecting portion 430 has a first side plate 431 and a second side plate 432 that are angled together and connected. The side of the first side plate 431 that is away from the second side plate 432 is connected to the tooth portion 420, and the second side plate 432 is arranged opposite to the tooth portion 420. By setting the connecting portion 430 to this angular structure, the structural strength of the connecting portion 430 can be improved, thereby improving the structural strength of the rack 400.
[0047] Preferably, the first side plate 431 and the second side plate 432 are connected by a rounded corner. This can alleviate the stress concentration problem at the junction of the first side plate 431 and the second side plate 432, reduce the probability of breakage at the junction of the first side plate 431 and the second side plate 432 of the connecting part 430, and improve the structural stability of the rack 400.
[0048] Specifically, the clearance opening 410 intersects with the apex of the connecting part 430, that is, part of the clearance opening 410 is located on the first side plate 431 and part is located on the second side plate 432. The part of the clearance opening 410 located on the second side plate 432 can avoid the connection structure (such as the connecting shaft) between the load-bearing body 300 and the sliding door 200. In addition, the clearance opening 410 is set in this way to improve the structural strength and facilitate the improvement of injection molding flow, thereby obtaining higher structural strength.
[0049] The aforementioned clearance opening 410 has four sides, which are defined as a first straight side 411, a second straight side 412, and two curved sides 413. The first straight side 411 is close to the toothed part 420, the second straight side 412 is away from the toothed part 420, and the two curved sides 413 are arranged opposite to each other. The two ends of each curved side 413 are connected to the first straight side 411 and the second straight side 412 respectively. Both curved sides 413 intersect with the apex corner of the connecting part 430. By setting the clearance opening 410 in this shape, the structural shape of the clearance opening 410 can be simplified as much as possible while avoiding the load-bearing part 300, thus reducing the processing difficulty.
[0050] Preferably, the two ends of the first straight edge 411 are connected to the two curved edges 413 by rounded corners. This can alleviate the stress concentration problem at the junction of the first straight edge 411 and the two curved edges 413, reduce the probability of breakage at the junction of the first straight edge 411 and the two curved edges 413 of the relief opening 410, and improve the structural stability of the rack 400.
[0051] Correspondingly, the two ends of the second straight edge 412 are connected to the two curved edges 413 by rounded corners. This can alleviate the stress concentration problem at the junction of the second straight edge 412 and the two curved edges 413, reduce the probability of breakage at the junction of the second straight edge 412 and the two curved edges 413 of the relief opening 410, and further improve the structural stability of the rack 400.
[0052] Specifically, the load-bearing body 300 on the sliding door 200 can be configured as a rolling element. In this way, when the sliding door 200 slides, the rolling element can roll along the drive box 100. This reduces the friction between the load-bearing body 300 and the drive box 100, which not only reduces energy consumption and improves the smoothness of the sliding door 200's movement, but also reduces wear between the load-bearing body 300 and the drive box 100, extending the service life of both the load-bearing body 300 and the drive box 100.
[0053] Preferably, see Figure 2 Bearings can be used as the load-bearing body 300. This can further reduce the friction between the load-bearing body 300 and the drive box 100, and reduce the resistance that the drive box 100 bears when sliding.
[0054] Specifically, the surface of the drive box 100 that mates with the bearing is a horizontal surface, and the rotation center of the bearing is set horizontally.
[0055] An electric motor can be used as the aforementioned rotational power source. By connecting the motor shaft and the gear coaxially, the rotational power can be transmitted between the motor and the gear.
[0056] The overall shape of the aforementioned rack 400 can be set to be arc-shaped, thus adapting to most air conditioner indoor units with arc-shaped front panels.
[0057] This embodiment also provides an air conditioner, which includes an air outlet frame and the aforementioned sliding door assembly, with the drive box mounted on the air outlet frame.
[0058] The air conditioner provided in this embodiment includes the above-mentioned sliding door assembly, and therefore has all the advantages of the above-mentioned sliding door assembly. The position of the moving part of the drive mechanism in conjunction with other components does not need to bear the weight of the moving part and the sliding door 200, but only needs to bear the transmission force, which reduces the force borne by the moving part. As a result, the moving part of the drive mechanism can operate more stably, and the sliding door driven by the moving part can slide more stably.
[0059] In summary, the embodiments of the present invention disclose a sliding door assembly and an air conditioner, which overcomes many technical defects of traditional sliding door assemblies in air conditioner indoor units. The sliding door assembly and air conditioner provided by the embodiments of the present invention allow the moving parts of the drive mechanism to operate more stably, thus enabling the sliding door 200 driven by the moving parts to slide more stably.
