Description

Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning (HVAC) equipment technology, and more particularly to a panel structure and HVAC equipment. Background Technology

[0002] In building HVAC systems, ceiling-mounted air outlets are widely used for indoor air conditioning. Traditional ceiling-mounted air outlets typically employ fixed grilles or louvers to guide airflow. A panel structure is usually installed at the outlet to prevent dust accumulation; however, existing panel structures suffer from issues such as incomplete sealing and unsightly appearance. Utility Model Content

[0003] This application provides a panel structure and HVAC equipment to solve the problems of poor sealing and unsightly appearance of the panel structure at the air outlet of existing HVAC equipment.

[0004] In a first aspect, this application provides a panel structure, including: an air outlet housing, the air outlet housing being provided with an air outlet, and the air outlet housing being able to be embedded in a ceiling;

[0005] A panel, which is movably disposed on the air outlet housing to close or open the air outlet;

[0006] When the panel is in the first state, the panel closes the air outlet, and the panel is flush with the air outlet housing; when the panel is in the second state, the panel opens the air outlet, and the panel is spaced apart from the air outlet housing.

[0007] By adopting the above technical solution, the panel structure achieves a tight connection between the panel and the housing. The panel structure includes an air outlet housing and a panel. The air outlet housing is embedded in the ceiling and has an air outlet. The panel is movably installed in the air outlet housing to close or open the air outlet.

[0008] In the specific implementation process, when the panel is in the first state (closed position), it completely closes the air outlet and remains flush with the air outlet housing, and its outer surface forms a uniform decorative surface with the air outlet housing; when the panel is in the second state (open position), the panel and the air outlet housing are spaced apart to form a ventilation channel.

[0009] It is understandable that, compared with the sliding or rotating panel solutions in the prior art, the panel structure of this application embodiment, through a movable connection, ensures both a tight fit between the panel and the shell when closed and a good ventilation effect when open, effectively solving the sealing and aesthetic problems of traditional structures.

[0010] In some embodiments of this application, the panel and the air outlet housing are configured such that, during the movement of the panel relative to the air outlet housing, the panel and the air outlet housing are arranged parallel to each other.

[0011] By ensuring that the panel remains parallel to the air outlet housing during opening and closing, smooth and reliable displacement control is achieved.

[0012] In some embodiments of this application, the panel structure includes a driving component, which includes a first link and a second link, wherein the first link and the second link are arranged parallel to each other and have the same length;

[0013] The first end of the first connecting rod is rotatably connected to the air outlet housing, and the second end of the first connecting rod is rotatably connected to the panel; the first end of the second connecting rod is rotatably connected to the air outlet housing, and the second end of the second connecting rod is rotatably connected to the panel.

[0014] The parallelogram drive mechanism, consisting of a first and second link of equal length, ensures that the panel remains parallel to the air outlet housing during movement. Geometric constraints maintain the accuracy of the motion trajectory, thereby improving the stability and reliability of the panel's opening and closing.

[0015] In some embodiments of this application, the driving component includes at least one limiting member;

[0016] The first end of the limiting member is rotatably connected to the first connecting rod, and the second end of the limiting member is rotatably connected to the second connecting rod; the extension direction of the limiting member is parallel to the line connecting the first end of the first connecting rod and the first end of the second connecting rod.

[0017] The parallel connection design of the limiting component creates a stable geometric constraint system, ensuring that the first and second links always move synchronously. The parallelogram mechanism formed by the limiting component, the first link, and the second link maintains the parallel movement trajectory of the panel, preventing deviation or jamming during movement.

[0018] In some embodiments of this application, the limiting member includes a first connecting portion and a second connecting portion;

[0019] The first connecting part is rotatably connected to the second end of the first connecting rod, and the second connecting part is rotatably connected to the second end of the second connecting rod.

[0020] The first and second connecting parts of the limiting member are rotatably connected to the first and second links respectively, thus constructing a rigid motion constraint frame to ensure that the first and second links always maintain synchronous parallel motion.

[0021] In some embodiments of this application, a first extension rod is provided at the second end of the first connecting rod, and the first extension rod passes through the first connecting rod;

[0022] The first extension rod is connected to the panel via the first connecting part;

[0023] The second end of the second connecting rod is provided with a second extension rod, which passes through the second connecting rod;

[0024] The second extension rod is connected to the panel via the second connecting part.

[0025] By inserting extension rods through the first and second links, the extension adjustment of the panel connection point is realized, enabling the panel to obtain a larger stroke and a more flexible installation position. The matching design of the extension rod and the connection part ensures the reliability of power transmission.

[0026] In some embodiments of this application, at least a portion of the first connecting portion is attached to the panel; at least a portion of the second connecting portion is attached to the panel.

[0027] The direct bonding design between the first and second connecting parts and the panel establishes a stable force transmission interface, ensuring that the driving force is evenly distributed to the entire panel, enhancing the connection rigidity, suppressing vibration and offset during movement, and providing a positioning reference for the panel.

[0028] In some embodiments of this application, the drive assembly further includes a drive member disposed on the air outlet housing;

[0029] The output end of the drive component is fixedly connected to the first connecting rod, and the drive component can drive the first connecting rod to rotate relative to the air outlet housing.

[0030] By rigidly connecting the output end of the drive component to the first link, precise power transmission is ensured, and the rotation of the first link drives the entire parallel four-bar linkage to move.

[0031] In some embodiments of this application, the driving member is provided with a rotating rod, which is rotatably connected to the second end of the second connecting rod.

[0032] By setting a rotating rod on the drive component and connecting it to the second link, an auxiliary motion constraint system is constructed, providing a stable rotational fulcrum for the second link. The rotational connection between the rotating rod and the second link ensures the synchronization and coordination of the movements of the first and second links, improving the stability of the panel translation.

[0033] Secondly, this application provides a heating, ventilation, and air conditioning (HVAC) device, including a panel structure as described in any of the first aspects. Attached Figure Description

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] In the field of building HVAC, ceiling-mounted air vents are widely used in indoor air conditioning systems. Traditional air vents mostly use fixed grilles or louver structures, which can achieve basic air supply functions, but cannot completely seal the air vents when the equipment is stopped, leading to dust accumulation and energy loss.

[0047] In existing technologies, sliding panel structures are often used at the air outlet, with the opening and closing of the air outlet controlled by the horizontal movement of the panel structure, or rotating panel structures are used, with the opening and closing of the air outlet achieved by the flipping movement of the panel structure. However, these solutions still have significant shortcomings: sliding panel structures are difficult to ensure to be completely flush with the shell when closed, which can easily create gaps; while rotating panel structures protrude from the ceiling plane when open, which affects aesthetics and takes up space.

[0048] Therefore, there is an urgent need for a panel structure solution that can be tightly closed and aesthetically pleasing.

[0049] To address the technical problem of incomplete panel closure and aesthetic impact in existing technologies, this application provides a panel structure that enables parallel movement and precise positioning of the panel. The panel structure includes an air outlet housing and a panel. The air outlet housing is embedded in the ceiling and has an air outlet. The panel is movably mounted on the air outlet housing to close or open the air outlet.

[0050] In the specific implementation process, when the panel is in the first state (closed position), it completely closes the air outlet and remains flush with the air outlet housing, and its outer surface forms a uniform decorative surface with the air outlet housing; when the panel is in the second state (open position), the panel and the air outlet housing are spaced apart to form a ventilation channel.

[0051] It is understandable that, compared with the sliding or rotating panel solutions in the prior art, the panel structure of this application embodiment, through a movable connection, ensures both a tight fit between the panel and the shell when closed and a good ventilation effect when open, effectively solving the sealing and aesthetic problems of traditional structures.

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0059] See Figures 1 to 6 This application provides a panel 200 structure, wherein the panel 200 structure may include an air outlet housing 100 and a panel 200.

[0060] The air outlet housing 100 can serve as a basic support component for the structure of the panel 200, and can be embedded in the ceiling to construct an airflow channel and provide an installation platform for the panel 200.

[0061] The air outlet housing 100 may be provided with an air outlet 110, which can form the main channel for airflow. The air outlet 110 can be designed with a regular geometric shape or an irregular shape according to actual ventilation requirements, and its edge can be provided with a guide structure to optimize the airflow direction. The arrangement of the air outlet 110 includes, but is not limited to, central placement, offset arrangement, or multi-hole array, to adapt to different airflow organization requirements.

[0062] The panel 200 is movably mounted on the air outlet housing 100 and can be used as a control component for the airflow channel to adjust the ventilation status and maintain the integrity of the decoration.

[0063] The movable configuration of panel 200 allows it to switch between open and closed states. Specific implementations of this movable connection include, but are not limited to, parallel movement, rotational motion, or a combination of these. In the parallel movement implementation, panel 200 can maintain its relative position to the air outlet housing 100 via guide rails or linkage mechanisms; in the rotational motion implementation, panel 200 can rotate around a fixed axis to achieve the opening and closing function.

[0064] The edge of the panel 200 may be provided with a sealing element, which can form a tight fit with the air outlet housing 100 in the closed state, effectively preventing airflow leakage and dust intrusion.

[0065] When the panel 200 is in the first state (i.e., the closed position), the panel 200 completely covers the air outlet 110 area, sealing the air outlet 110 and blocking the airflow path, which can prevent dust accumulation when not in operation. At this time, the panel 200 can be flush with the air outlet housing 100, so that the outer surface of the panel 200 and the outer contour of the air outlet housing 100 are coplanar.

[0066] When the panel 200 is in the second state (i.e., the open position), the panel 200 can open the air outlet 110. The panel 200 and the air outlet housing 100 can be spaced apart. The space formed between the panel 200 and the air outlet housing 100 can form a channel for airflow, while avoiding structural interference with the ceiling.

[0067] Through the coordinated design of the air outlet housing 100 and the panel 200, the opening and closing states of the air outlet 110 can be controlled and integrated with the ceiling decoration surface. The embedded installation of the air outlet housing 100 ensures structural stability and guides the movement of the panel 200, allowing it to remain flush with the housing when closed, forming a seamless decorative surface. The two working states of the panel 200 can achieve a seal to prevent dust accumulation when closed, and form an airflow channel when open, ensuring ventilation efficiency. In this way, the functional requirements of the equipment are met while maintaining the overall aesthetics of the ceiling decoration.

[0068] As a specific embodiment of this application, such as Figure 5 and Figure 6 As shown, the panel 200 and the air outlet housing 100 in this embodiment can be configured such that the panel 200 can be arranged parallel to the air outlet housing 100 during the movement of the panel 200 relative to the air outlet housing 100.

[0069] The specific manifestation of this parallel relative setting can be as follows: no matter where the panel 200 is in the movement trajectory, its plane normal direction is always parallel to the reference plane of the air outlet housing 100, and the distance between the edge of the panel 200 and the corresponding contour of the air outlet housing 100 remains uniform.

[0070] When the panel 200 moves, the panel 200 remains parallel to the air outlet housing 100, which ensures that the panel 200 maintains a stable spatial posture during the displacement process, avoids deflection or tilting, and thus ensures that the panel 200 fits and seals with the housing when closed.

[0071] As a specific embodiment of this application, the panel 200 structure may include a drive component 300. The drive component 300 can be used to control the movement of the control panel 200, undertaking the functions of power transmission and motion guidance. The drive component 300 can convert the input of the drive source into the parallel movement of the panel 200, realizing smooth control of the opening and closing process of the air outlet 110.

[0072] like Figure 3 and Figure 4 As shown, the drive assembly 300 may include a first link 310 and a second link 320, which can be arranged in parallel and have the same length. The parallel and equal-length configuration of the first link 310 and the second link 320 can form a parallelogram linkage mechanism, which can constrain the movement trajectory of the panel 200, avoid posture deviations during movement, and ensure that it maintains a parallel relationship with the air outlet housing 100 during displacement. The equal length of the first link 310 and the second link 320 can ensure the balance of power transmission, and the parallel arrangement can eliminate torque imbalance during movement.

[0073] The first end of the first connecting rod 310 can be rotatably connected to the air outlet housing 100, and the second end of the first connecting rod 310 can be rotatably connected to the panel 200. The first end of the second connecting rod 320 can be rotatably connected to the air outlet housing 100, and the second end of the second connecting rod 320 can be rotatably connected to the panel 200.

[0074] The first link 310 and the second link 320 adopt the same connection method, forming a revolute joint at both ends of the first link 310 and the second link 320, respectively. The revolute connection of the first link 310 and the second link 320 can form a fixed fulcrum, and the position of this connection point can determine the movement trajectory and displacement range of the panel 200. In specific implementations, a pin connection, ball joint, or bearing connection can be used to ensure flexible rotation and no backlash. The revolute connection between the first link 310, the second link 320, and the panel 200 forms the motion output end, and its connection strength can affect the reliability of power transmission.

[0075] By setting up the first link 310 and the second link 320, it can be ensured that the panel 200 always maintains the predetermined parallel posture during the movement. The load on individual connection points is reduced by the symmetrical force distribution, making the opening and closing action of the panel 200 more stable and smooth.

[0076] As a specific embodiment of this application, the drive component 300 may include at least one limiting member 330. The limiting member 330 may be used to control the range of motion of the control panel 200 and to ensure that the panel 200 is parallel to the air outlet housing 100 when it moves.

[0077] The limiting member 330 can be positioned and connected in various ways within the drive assembly 300. For example, the limiting member 330 can be laterally connected between the first link 310 and the second link 320 to form a stable triangular support structure; or it can be longitudinally positioned between the first link 310, the second link 320, and the panel 200 or the air outlet housing 100 as a mechanical stop to terminate the stroke.

[0078] The specific form of the limiting member 330 includes, but is not limited to, a rigid connecting rod, an adjustable stop block, or an elastic buffer device, etc., and its mounting node can be set at the middle or end position of the first link 310 and the second link 320. The connection between the limiting member 330 and the first link 310 and the second link 320 can be a revolute joint to maintain the freedom of movement of the mechanism.

[0079] For example, the first end of the limiting member 330 can be rotatably connected to the first link 310, and the second end of the limiting member 330 can be rotatably connected to the second link 320. The limiting member 330, together with the first link 310 and the second link 320, constitutes a parallel linkage mechanism. The two ends of the limiting member 330 form rotational connection points with the first link 310 and the second link 320, respectively, and together with the fixed fulcrum of the first link 310 and the second link 320 on the air outlet housing 100, they determine the four vertices of the parallelogram.

[0080] The extension direction of the limiting member 330 can be parallel to the line connecting the first end of the first link 310 and the first end of the second link 320. The parallel relationship between the extension direction of the limiting member 330 and the line connecting the two fixed support points on the housing can ensure that the entire mechanism maintains strict geometric constraints during movement.

[0081] The drive assembly 300 may include multiple limiting members 330. These limiting members 330, by adding constraint points, enable control of the movement trajectory of the panel 200. The multiple limiting members 330 can be arranged in parallel to form a multiple parallelogram mechanism, or at an angle to construct spatial constraints. Each limiting member 330 maintains a rotational connection with its corresponding link, collectively forming a composite rigid frame system that enhances constraints within the plane of motion and provides stability control perpendicular to the direction of motion.

[0082] For example, the drive assembly 300 may include a first limiting member 330a and a second limiting member 330b. The first limiting member 330a and the second limiting member 330b may be respectively disposed on both sides of the second link 320 of the first link 310 to form a spatially symmetrical constraint structure.

[0083] The first connecting portion 331 of the first limiting member 330a can be rotatably connected to the left side of the first connecting rod 310, the second connecting portion 332 of the first limiting member 330a can be rotatably connected to the left side of the second connecting rod 320, the first connecting portion 331 of the second limiting member 330b can be rotatably connected to the right side of the first connecting rod 310, and the second connecting portion 332 of the second limiting member 330b can be rotatably connected to the right side of the second connecting rod 320. The first limiting members 330a and the second limiting members 330b on both sides cooperate with each other during movement.

[0084] A first mounting opening can be formed between the first limiting member 330a and the panel 200, and a second mounting opening can be formed between the second limiting member 330b and the panel 200.

[0085] The wiring 400 of the HVAC equipment can be located between the first limiting member 330a and the second limiting member 330. The first end of the wiring can be located outside the first mounting port, and the second end of the wiring can be located inside the second mounting port.

[0086] As a specific embodiment of this application, the limiting member 330 may include a first connecting portion 331 and a second connecting portion 332. The first connecting portion 331 may be rotatably connected to the second end of the first connecting rod 310, and the second connecting portion 332 may be rotatably connected to the second end of the second connecting rod 320.

[0087] The rotational connection between the first connecting part 331 and the second end of the first connecting rod 310 forms a first kinematic pair, and the rotational connection between the second connecting part 332 and the second end of the second connecting rod 320 forms a second kinematic pair. The cooperative work of the first connecting part 331 and the second connecting part 332 can ensure the synchronous movement of the limiting member 330 with the first connecting rod 310 and the second connecting rod 320. Specific implementations of the connecting parts include, but are not limited to, connecting lugs with shaft holes, ball joint connectors, or universal joint structures, etc., and their rotation axes can be set to be parallel or intersecting as needed.

[0088] As a specific embodiment of this application, the second end of the first connecting rod 310 may be provided with a first extension rod 311, which may pass through the first connecting rod 310. The first extension rod 311 may be connected to the panel 200 through the first connecting part 331.

[0089] The first extension rod 311 can serve as a transmission component between the first connecting rod 310 and the panel 200, undertaking the functions of connection conversion and force transmission. The first end of the first extension rod 311 can pass through the interior of the first connecting rod 310 to form a relatively sliding fit. The second end of the first extension rod 311 can be connected to the panel 200 through the first connecting part 331, making the first extension rod 311 a structure connecting the first connecting rod 310 and the panel 200, directly transmitting the movement and driving force of the first connecting rod 310 to the panel 200.

[0090] For example, the first end of the first extension rod 311 can be rigidly fixedly connected to the second end of the first connecting rod 310, and the second end of the first extension rod 311 can be rotatably connected to the first connecting part 331; or, the first end of the first extension rod 311 can be rigidly rotatably connected to the second end of the first connecting rod 310, and the second end of the first extension rod 311 can be rotatably connected to the first connecting part 331. In this case, the parallelism of the panel 200 can be maintained by the parallel constraint of the first connecting part 331 and the second connecting part 332 in the limiting member 330.

[0091] The second end of the second link 320 may be provided with a second extension rod 321, which may pass through the second link 320. The second extension rod 321 may be connected to the panel 200 through the second connecting part 332.

[0092] The second extension rod 321 can serve as a transmission component between the second connecting rod 320 and the panel 200, undertaking the functions of connection conversion and force transmission. The first end of the second extension rod 321 can pass through the interior of the second connecting rod 320 to form a relatively sliding fit. The second end of the second extension rod 321 can be connected to the panel 200 through the second connecting part 332, making the second extension rod 321 a structure connecting the second connecting rod 320 and the panel 200, directly transmitting the movement and driving force of the second connecting rod 320 to the panel 200.

[0093] For example, the first end of the second extension rod 321 can be rigidly fixedly connected to the second end of the second connecting rod 320, and the second end of the second extension rod 321 can be rotatably connected to the second connecting part 332; or, the first end of the second extension rod 321 can be rigidly rotatably connected to the second end of the second connecting rod 320, and the second end of the second extension rod 321 can be rotatably connected to the second connecting part 332. In this case, the parallelism of the panel 200 can be maintained by the parallel constraint of the first connecting part 331 and the second connecting part 332 in the limiting member 330.

[0094] As a specific embodiment of this application, at least a portion of the first connecting portion 331 can be attached to the panel 200; at least a portion of the second connecting portion 332 can be attached to the panel 200.

[0095] The first connecting part 331 and the second connecting part 332 can form a direct mechanical coupling between the limiting member 330 and the panel 200, and transmit the moving force of the first link 310 and the second link 320 to the panel 200, ensuring that the driving force is evenly distributed and reducing vibration and deviation during the movement.

[0096] The design of the contact areas between the first connecting portion 331, the second connecting portion 332, and the panel 200 can have various implementations. For example, the contact surfaces can be designed as planar contacts to improve load-bearing capacity, or they can be curved contacts to accommodate the specific movement trajectory of the panel 200. The area and shape of the contact portions can be adjusted according to load requirements, including but not limited to partial boss contact, continuous edge contact, or distributed multi-point contact.

[0097] As a specific embodiment of this application, the drive component 300 may include a drive element 340, which may be disposed on the air outlet housing 100. The drive element 340 may serve as a power source for the movement of the panel 200, and its placement on the air outlet housing 100 may optimize the power transmission path and simplify the overall system architecture.

[0098] The output end of the drive component 340 can be fixedly connected to the first link 310, and the drive component 340 can drive the first link 310 to rotate relative to the air outlet housing 100. The fixed connection between the output end of the drive component 340 and the first link 310 ensures that the output torque of the drive component 340 can be converted into the rotational motion of the first link 310, thereby controlling the opening and closing state of the control panel 200.

[0099] The driving component 340 applies a driving force to the first link 310 to drive the panel 200. The output of the driving component 340 can be synchronously transmitted to the entire structure of the panel 200, improving energy utilization efficiency. When the driving component 340 acts on the first link 310, the rotational torque it generates can be transmitted through the first link 310 to the first extension rod 311 and the limiting component 330, thereby driving the panel 200 to move as a whole. During this process, the second link 320 can automatically follow the movement of the first link 310 through the geometric constraint relationship of the limiting component 330, forming a coordinated double-link motion mode. In this way, the motion characteristics of the parallelogram linkage mechanism can be utilized to achieve synchronous operation of the entire mechanism through the configuration of the first link 310, the second link 320, and the limiting component 330.

[0100] As a specific embodiment of this application, the driving member 340 of this embodiment may be provided with a rotating rod 341, and the rotating rod 341 may be rotatably connected to the second end of the second connecting rod 320.

[0101] The rotating rod 341 can serve as an auxiliary component of the drive system, transmitting the output motion of the drive member 340 to the second link 320. By fixing the rotating rod 341 to the drive member 340, the movement of the second link 320 can be guided, ensuring the synchronization and stability of the movements of the first link 310 and the second link 320.

[0102] When the output end of the drive unit 340 drives the first link 310 to rotate, the first link 310 transmits motion to the second link 320 through the constraint relationship of the limiting member 330. At this time, the rotating rod 341 fixed to the housing of the drive unit 340 can provide a definite rotation center for the second link 320, so that the motion trajectory of the second link 320 follows the geometric constraints of the parallelogram linkage mechanism. This fulcrum setting method and the synergistic effect of the limiting member 330 together ensure the parallel movement characteristics of the panel 200. The rotational connection point between the rotating rod 341 and the second link 320 can use a spherical bearing or a self-aligning hinge to compensate for the small displacement caused by installation deviation.

[0103] In summary, the overall movement process of panel 200 structure is as follows:

[0104] When the drive unit 340 is activated, its output end directly drives the first connecting rod 310 to rotate around a fixed fulcrum on the air outlet housing 100. This rotational motion is transmitted to the first connecting part 331 through the first extension rod 311, thereby pushing the panel 200 to begin displacement. At the same time, the rotating rod 341 fixed to the housing of the drive unit 340 provides a stable rotational reference for the second connecting rod 320, so that the second connecting rod 320 moves synchronously under the drive of the first connecting rod 310 through the limiting member 330. The movement of the second connecting rod 320 is then transmitted to the second connecting part 332 through the second extension rod 321, working together with the first connecting part 331 to control the movement trajectory of the control panel 200.

[0105] Throughout the movement, the limiting member 330, by connecting the first connecting part 331 and the second connecting part 332, forcibly maintains the parallel relationship between the two, ensuring that the panel 200 always maintains a parallel posture with the air outlet housing 100.

[0106] When the panel 200 transitions from a closed state to an open state, all components work in concert: the rotational motion output by the drive unit 340 is converted into the initial displacement of the panel 200 through the first connecting rod 310; the limiting member 330 drives the second connecting rod 320 to respond synchronously; and the rotating rod 341 ensures that the movement trajectory of the second connecting rod 320 is accurate. Finally, under the combined action of the first connecting part 331 and the second connecting part 332, the panel 200 moves smoothly outward, forming a uniform ventilation gap.

[0107] Regarding the movement trajectory of panel 200, the parallelogram linkage mechanism first drives panel 200 to move horizontally, and then, through a preset movement path, causes panel 200 to continue moving outward while descending moderately. This movement method of first moving horizontally and then descending ensures that the air outlet 110 has sufficient opening area to guarantee ventilation efficiency; on the other hand, by controlling the descent height, it avoids structural interference that may occur between panel 200 and the edge of the ceiling when it is open.
