Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, specifically to a moving door mechanism and an air conditioner. Background Technology

[0002] Air conditioner door mechanisms commonly employ rack and pinion transmission as the core method for opening and closing the door. This includes a motor-driven gear, a rack connected to the door, and auxiliary guide components. Over long-term use, this method suffers from a relatively complex structure and high requirements for meshing precision and assembly tolerances, leading to increased costs and inconvenient maintenance. Furthermore, during operation, wear, dust accumulation, or thermal deformation can cause jamming or even seizure, resulting in insufficient reliability. Additionally, the significant frictional resistance generated by the meshing of the gears can easily cause vibration and noise. Moreover, this transmission method relies on lubrication; in the environment of significant temperature and humidity fluctuations inside the air conditioner, the lubricant's performance easily deteriorates, further exacerbating wear and the risk of jamming. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a moving door mechanism and an air conditioner to solve the technical problem that the door is prone to jamming or getting stuck in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The sports gate mechanism includes:

[0006] Air guide frame;

[0007] The door body is provided with a rotating shaft, which is configured to be driven by a motor to rotate the door body relative to the air guide frame, so as to make the door body open or closed.

[0008] The support assembly includes a first support structure and a second support structure, which are arranged sequentially from the inside to the outside and are located between the air guide frame and the door body to jointly support the door body and can move synchronously with the door body.

[0009] Furthermore, the door body is provided with a bracket, and the bracket has a fixing opening for fixing the first support structure and / or the second support structure.

[0010] Furthermore, the bracket has a recessed portion that bends toward the door body, and two fixing posts are provided on two opposite inner sides of the recessed portion, forming the fixing opening between the two fixing posts.

[0011] Furthermore, the bracket is provided with several notches for connecting the fixing port, and each notch is provided with a spring clip, which has a rebound force when squeezed by the first support structure or the second support structure.

[0012] Furthermore, the air guide frame is provided with a first motion track and a second motion track. Both the first motion track and the second motion track extend along the rotation direction of the door body and correspond one-to-one with the first support structure and the second support structure, so as to guide them to follow the movement of the door body.

[0013] Furthermore, the first support structure and the first motion track are respectively a gear and a tooth groove, the gear being rotatably mounted on the door body and meshing with the tooth groove.

[0014] Furthermore, both the first support structure and the second support structure are rollers, and both the first motion track and the second motion track are grooves, with the rollers rotating and fitting into the grooves.

[0015] Furthermore, the air guide frame is provided with a through hole to accommodate the rotating shaft.

[0016] Furthermore, both the rotating shaft and the support assembly are configured as two sets, located on the upper and lower end faces of the door body, respectively.

[0017] An air conditioner, including the aforementioned moving door mechanism.

[0018] Compared to existing technologies, this invention offers the following advantages: By directly driving the rotating shaft with a motor to rotate the door, replacing the original gear and rack drive method, it not only reduces the requirements for parts machining accuracy and assembly tolerances, making installation, debugging, and subsequent maintenance simpler, but also eliminates the risk of jamming caused by long-term meshing wear, dust accumulation, or heat deformation of the gear and rack. Furthermore, by utilizing the rotating shaft drive method in conjunction with the support components, the support components can jointly bear the door's load and move synchronously with it, forming a stable and balanced support system. This helps the door maintain its preset movement trajectory, improving the smoothness and consistency of door movement, making the door quieter and smoother during opening and closing, and preventing jamming. Simultaneously, it eliminates the need for lubricants to ensure transmission performance, has strong environmental adaptability, and a longer service life. Attached Figure Description

[0036] The present invention will be further described in detail below through specific embodiments:

[0037] In embodiments of the present invention, such as Figures 1-6 As shown, the moving door mechanism includes: an air guide frame 1, a door body 2, and a support assembly; the door body 2 is provided with a rotating shaft 201, which is configured to be driven by a motor to rotate the door body 2 relative to the air guide frame 1, so that the door body 2 is in an open or closed state; the support assembly includes a first support structure 3 and a second support structure 4, which are arranged sequentially from the inside to the outside and are located between the air guide frame 1 and the door body 2 to jointly support the door body 2 and can move synchronously with the door body 2.

[0038] Specifically, in this embodiment of the invention, the door body 2 is rotatably connected to the air guide frame 1, allowing the door body 2 to rotate relative to the air guide frame 1 to form an open or closed state. To eliminate the traditional gear and rack transmission method, this embodiment provides a rotating shaft 201 at the door body 2. This rotating shaft 201 is rotatably mounted on the air guide frame 1 and directly driven by a motor. This simplifies assembly, reduces the machining precision and assembly tolerance of parts, and eliminates the risk of jamming caused by long-term meshing wear, dust accumulation, or heat deformation of the gear and rack. It also avoids friction and impact generated during tooth meshing, making the door body 2 quieter and smoother during opening and closing.

[0039] In this embodiment of the invention, in order to avoid the problem of shaking and abnormal noise caused by the weight of the door 2, a first support structure 3 and a second support structure 4 are provided between the air guide frame 1 and the door 2. The first support structure 3 and the second support structure 4 are independently provided and can move together with the door 2 to jointly support the door 2.

[0040] Thus, the first support structure 3, as the support point closest to the rotating shaft 201, can bear the torsional force transmitted by the motor torque, ensuring that the start and stop response of the door body 2 rotation is rapid and without delay. It provides primary radial and axial support and limit, preventing the door body 2 from swaying significantly at its base. Of course, the first support structure 3 can also share most of the bending moment generated by the weight of the door body 2 itself or external wind pressure, so that the rotating shaft 201 mainly bears pure torque, reducing the burden on the rotating shaft 201 and the motor bearings, and improving the durability of the mechanism.

[0041] Similarly, the second support structure 4, acting as an outer support point, bears the downward force generated by the weight of the far end of the door body 2 away from the rotation axis 201, and can resist the overturning moment that may be brought by the airflow during operation, effectively preventing the door body 2 from deforming or jamming due to gravity or uneven force. In other words, the second support structure 4 provides a stable support for the far end of the door body 2, and works together with the first support structure 3 to ensure the accuracy and stability of the movement trajectory of the door body 2 throughout the opening and closing process, avoiding shaking or drifting at the end, and preventing the door body 2 from jamming or getting stuck.

[0042] Furthermore, when the first support structure 3 and the second support structure 4 cooperate with the rotating shaft 201, a synergistic effect of drive and support is achieved. Specifically, the rotating shaft 201 provides the rotational torque, ensuring a simple and reliable structure; while the support components serve as load-bearing and guiding elements, capable of withstanding static and dynamic loads such as gravity and wind pressure, and guiding the movement trajectory of the door 2. Failure of any one component will not affect the use of the remaining components. Moreover, the rotating shaft 201 forms the first fulcrum, and the first support structure 3 and the second support structure 4 respectively form the second and third fulcrums, expanding outwards to provide more stable support and prevent the door 2 from jamming during movement. Of course, because the rotating shaft 201 and the support components are independently configured, the load-bearing surface and the drive surface of this mechanism are separated, making the normal pressure and force direction between the load-bearing surfaces more controllable. The frictional resistance is far less than the high-pressure contact and relative sliding between the gear and rack meshing surfaces, thus ensuring quieter operation, lower energy consumption, and slower wear of the door 2. During assembly, the rotating shaft 201 can be fixed first, and the rotating shaft 201 can be used as the driving center. Then, the height and gap of the two support structures can be adjusted to reduce their cumulative tolerance.

[0043] In this embodiment, the door body 2 is rotated by directly driving the rotating shaft 201 with a motor, replacing the original gear and rack drive. This simplifies the structure and avoids the door body 2 from jamming or getting stuck due to wear of the gear and rack. At the same time, the door body 2 is supported by the first support structure 3 and the second support structure 4 to share the weight of the door body 2. This weight can be applied to the air guide frame 1 to prevent the door body 2 from shaking and thus enable the door body 2 to open and close smoothly.

[0044] like Figures 4-7 As shown, in one embodiment, the door body 2 is provided with a bracket 5, the bracket 5 having a fixing opening 501 for fixing the first support structure 3 and / or the second support structure 4. Specifically, in order to install the first support structure 3 and the second support structure 4 to the door body 2, this embodiment provides a corresponding number of brackets 5 on the door body 2, and the fixing opening 501 formed by the bracket 5 can be used to fix the corresponding support structure.

[0045] Preferably, such as Figure 7 , Figure 8 As shown, in one embodiment, the bracket 5 has a recessed portion 502 that bends toward the door body 2. Two fixing posts are provided on two opposite inner sides of the recessed portion 502, and the fixing posts form the fixing opening 501. Specifically, in order to facilitate the assembly of the support structure into the fixing opening 501, in this embodiment, the bracket 5 has a recessed portion 502 that bends toward the door body 2, and two fixing posts are fixed on its inner side. The fixing opening 501 is formed between the two fixing posts, so that the support structure can be embedded into the fixing opening 501 and axially positioned by the fixing posts.

[0046] Preferably, such as Figure 7 , Figure 8 As shown, the bracket 5 is provided with several notches 503 for communicating with the fixing port 501. Each notch 503 has a spring clip 504, which has a rebound force due to compression from the first support structure 3 or the second support structure 4. Specifically, to facilitate faster installation of the support structure into the fixing port 501 and to prevent the support structure from detaching from the fixing port 501, this embodiment provides notches 503 on the surface of the bracket 5, which communicate with the fixing port 501, and provides spring clips 504 at these notches. Thus, when the support structure is inserted into the fixing port 501 from bottom to top, the compression of the spring clip 504 by the support structure deforms it. This deformation gives the spring clip 504 a restoring rebound force, which acts on the support structure within the fixing port 501, thus firmly fixing the support structure within the fixing port 501. Of course, as... Figure 8 As shown, this embodiment is provided with four spring clips 504, which are arranged in pairs to clamp the opposite end faces of the support structure.

[0047] like Figures 4-6 As shown, in one embodiment, the air guide frame 1 is provided with a first motion track 6 and a second motion track 7. Both the first motion track 6 and the second motion track 7 extend along the rotation direction of the door body 2 and correspond one-to-one with the first support structure 3 and the second support structure 4, guiding them to follow the movement of the door body 2. Specifically, the tracks can bear the weight and wind pressure of the door body 2, and also guide the corresponding support structures. That is, the tracks extend along the rotation direction of the door body 2, providing path constraints for the first support structure 3 and the second support structure 4, ensuring that the movement trajectory of the door body 2 is fixed and repeatable regardless of its load state, eliminating the risk of trajectory drift or jamming caused by force deformation or assembly gaps. Of course, the dual tracks provide two constrained guide points for the door body 2, forming a stable motion system together with the rotation axis 201, suppressing the swaying or vibration of the door body 2 during movement, and achieving smooth opening and closing. Furthermore, since the track structure is formed at the air guide frame 1, it can provide a larger contact area and a more favorable force direction to withstand the pressure transmitted from the support structures. During assembly, simply place the support structure into the corresponding track. Adjusting the smoothness of the door body 2 rotation also only requires fine-tuning the gap between the track or support structure, simplifying the assembly process.

[0048] like Figure 6 and Figure 9As shown in Figure a, in one embodiment, the first support structure 3 and the first motion track 6 are a gear and a toothed groove, respectively. The gear is rotatably mounted on the door body 2 and meshes with the toothed groove. Specifically, the meshing of the gear and the toothed groove ensures that when the door body 2 rotates under the drive of the rotating shaft 201, the inner gear and the toothed groove on the air guide frame 1 move synchronously according to the tooth pitch. This avoids the asynchronous movement of the inner and outer support points that may be caused by uneven resistance or slight slippage, which could lead to slight twisting and deformation of the door body 2. Of course, the main drive in this mechanism is still the rotating shaft 201, and the motor does not need to bear the high starting torque to overcome the initial resistance of gear meshing, nor does it need to use a complex gearbox with a high reduction ratio. As a follower component of the door body 2, it can still be driven by the rotating shaft 201 to make the door body 2 operate with low noise.

[0049] Of course, in another embodiment, in order to reduce friction between the gear and the tooth groove, such as Figure 9 As shown in Figure b, both the first support structure 3 and the second support structure 4 are rollers, and both the first motion track 6 and the second motion track 7 are grooves. The rollers rotate and fit into the grooves. This results in rolling friction between the rollers and the grooves, with a friction coefficient lower than that of gear and rack meshing friction. This significantly reduces the driving torque required for the door body 2 to move, resulting in a smaller motor load and smoother operation.

[0050] like Figure 4 As shown, in one embodiment, the air guide frame 1 is provided with a through hole 101 to accommodate the rotating shaft 201. Figures 3-6 As shown, both the rotating shaft 201 and the support assembly are configured in two sets, located on the upper and lower end faces of the door body 2, respectively. The symmetrical arrangement of the rotating shaft 201 and support assembly on both the upper and lower end faces of the door body 2 increases support for the door body 2, ensuring smooth movement, more uniform closure, and smaller gaps.

[0051] This embodiment also provides an air conditioner, including the aforementioned moving door mechanism. The specific structure of the moving door mechanism is as described in the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
