[0002] As an important household appliance for regulating indoor temperature and comfort, the design of the air outlet structure of an air conditioner directly affects the user's air delivery experience, the overall aesthetics of the unit, and its safety.

In addition, the overall appearance of the vent structure is messy and not simple, and the grille and air guide blades of the vent structure have poor coordination and low air control efficiency.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] In related technologies, the structure and air control method of the air conditioner vent cause cold air to blow directly on the user, resulting in poor user comfort. In addition, the overall appearance of the vent structure is messy and not simple, and the fit between the vent grille and the air guide blades is low, resulting in low air control efficiency.

[0028] To solve the above technical problems, refer to Figures 1 to 4 This application provides a wind control panel assembly, including a wind control panel frame 100, a grille strip 200, a first sweeping blade, and a second sweeping blade.

[0029] The air control panel frame 100 has an air inlet side 110 and an air outlet side 120; There are at least two grille bars 200, each located on the front side of the air outlet side 120; the grille bars 200 extend along a first direction, and the grille bars 200 are spaced apart along a second direction; the first direction and the second direction intersect. The first and second sweeping blades are both rotatably mounted within the air control panel frame 100; the second sweeping blade extends along the first direction, and the first sweeping blade extends along the second direction; along the front-rear direction, both the first and second sweeping blades are located on the rear side of the grille bar 200.

[0030] The front-to-back direction is parallel to the direction from the air inlet side 110 to the air outlet side 120. The grille strip 200 on the front side of the air outlet side 120 of the air control panel frame 100 serves as the outermost physical barrier, preventing fingers, large particles, or foreign objects from directly contacting the high-speed moving first and second sweeping blades inside. This prevents the first and second sweeping blades from potentially pinching the user or being easily damaged by external forces during their movement.

[0031] Three-dimensional air control is achieved by controlling the airflow in the left and right directions using one of the first and second sweeping blades and controlling the airflow in the up and down directions using the other. By placing both the first and second sweeping blades behind the grille bar 200, both the first and second sweeping blades are hidden behind the grille bar 200, achieving three-dimensional concealed air control.

[0032] Moreover, the airflow is divided when it passes through the first and second sweeping blades, as well as when it passes through the grille bar 200. This airflow control method can prevent the airflow from blowing directly on the user, prevent the user from feeling uncomfortable, and achieve a windless feeling.

[0033] The grille strip 200 can be designed to be relatively regular and neat, providing a unified and minimalist visual appearance. Hiding the first and second sweeping blades behind the grille strip 200 makes the air control panel frame 100 look cleaner, preventing the movement of the internal first and second sweeping blades from disrupting the overall static aesthetic. The grille strip 200 is located on the front side of the air outlet side 120, that is, on the outermost side of the air control panel frame 100, providing general directional guidance.

[0034] The airflow entering the air control panel frame 100 from the air inlet side 110 is often turbulent. After the initial cutting and three-dimensional guidance by the internal first and second sweeping blades, the airflow becomes smoother and reduces turbulence as it passes through the external grille strip 200.

[0035] The first and second sweeping blades are located within the air control panel frame 100 and behind the grille bar 200. The airflow entering from the air inlet side 110 will first pass through the first and second sweeping blades to change direction, and then be accelerated or rectified by the nozzle effect of the grille bar 200, which helps the wind to blow further and more gently.

[0036] When high-speed airflow flows directly over the moving first and second sweeping blades, it may generate wind-cutting noise. With the obstruction and buffering of the outer grille strip 200, the mechanical movement noise and airflow cutting noise inside the air control panel frame 100 can be reduced to a certain extent, making it sound quieter.

[0037] The first sweeping blade extends along the second direction, and the second sweeping blade extends along the first direction. The first and second directions intersect, meaning they can form an angle, so that when the airflow passes through this mesh, it is decomposed into components of different directions, allowing the air blown out from the grille bar 200 to blow into all corners of the room, namely the upper left, lower left, upper right, and lower right corners, forming a three-dimensional wind.

[0038] The first and second sweeping blades, extending in different directions, divide the air outlet side 120° into many small rectangular channels. This helps to break up the rough airflow, making the airflow softer and more delicate, and avoiding direct airflow that could cause discomfort to the human body.

[0039] In interior design, horizontal lines can visually widen the space. Air conditioners are typically mounted on the upper part of the wall, and the grille 200 extends along the first direction, which can be a straight line. This grille 200 makes the air control panel frame 100 look longer and more elegant, echoing the horizontal lines of the wall and ceiling, and appearing more stable.

[0040] The prevailing airflow direction within the air control panel frame 100 is typically forward. The straight grille bars 200 offer minimal obstruction to the airflow. Compared to wavy or complex geometric shapes, the straight grille bars 200 are the shortest, resulting in minimal friction loss, maximizing airflow volume, and extending the air delivery distance.

[0041] When the grid strip 200 is produced using an injection mold, the grid strip 200 extends in a straight line along the first direction, making demolding easy and less prone to deformation. This ensures high yield and dimensional accuracy during mass production, thereby reducing costs.

[0042] At least two grille strips 200 are arranged at intervals along the second direction. The spacing between two adjacent grille strips 200 can be constant, ensuring that the opening area at all positions above and below the air outlet is consistent, resulting in uniform airflow and reduced wind noise. The arrangement of at least two grille strips 200 at intervals along the second direction ensures that the air velocity and air volume of the entire air outlet remain consistent.

[0043] When the wind control panel frame 100 is a long strip structure, at least two grille strips 200 are equivalent to adding multiple reinforcing ribs to the frame, thereby improving the mechanical strength of the wind control panel frame 100.

[0044] Because the grille bars 200 are arranged in an arc along the second direction, the arc-shaped spacing makes the middle grille bars 200 far from the internal components, while the upper and lower grille bars 200 are close to the internal components. This inconsistency in distance will cause air leakage. When the air guide plate wants to push the air downward, because the upper and lower ends of the panel are close to the air guide plate, the airflow will escape from the upper and lower directions first and cannot be accurately guided.

[0045] The external multiple grille strips 200 of this application are arranged in a straight line at intervals along the second direction, parallel to the internal first and second sweeping blades, and have the same spacing as the first and second sweeping blades, resulting in more precise and efficient control of the airflow direction. The multiple grille strips 200 arranged at intervals along the second direction ensure that the airflow experiences consistent obstruction and rectification effects in the middle and both ends when passing through the grille strips 200.

[0046] The grille strips 200 extend in a straight line along the first direction and are spaced apart along the second direction, so that the first sweeping blade or the second sweeping blade can completely cover the air outlet between each two adjacent grille strips 200, which has a better dustproof effect and is more aesthetically pleasing.

[0047] The first and second swept blades extend along the second and first directions, respectively, meaning they can extend in a straight line. When the first and second swept blades are placed side by side, they can uniformly change the direction of the airflow, maintaining laminar flow and reducing turbulence.

[0048] The air entering the air control panel frame 100 from the air inlet side 110 flows parallel forward. The straight-extending first and second sweeping blades cut the airflow regularly. The airflow speed is consistent as it flows over the surface, preventing the formation of eddies, thereby reducing noise and increasing the blowing distance. The straight-extending first and second sweeping blades also prevent the first and second sweeping blades from breaking or becoming out of sync with each other after long-term use.

[0049] Optionally, such as Figure 1 and Figure 2 As shown, the first direction is the left-right direction, and the second direction is the up-down direction; the first sweeping blade is the left-right sweeping blade 400, and the second sweeping blade is the up-down sweeping blade 300. Along the direction from the air inlet side 110 to the air outlet side 120, the left-right sweeping blade 400, the up-down sweeping blade 300, and the grille strip 200 are arranged in sequence.

[0050] The innermost layer of the air control panel frame 100 consists of left and right sweeping blades 400, the middle position of the air control panel frame 100 is provided with upper and lower sweeping blades 300, and the outermost layer is fixed with a grille strip 200.

[0051] When the airflow is first redirected by the left and right sweeping blades 400 inside the air control panel frame 100, for example, blown to the left or right, the airflow will rush towards the up and down sweeping blades 300 with a lateral velocity component. The lateral airflow can slide laterally along the surface of the up and down sweeping blades 300 extending in the left and right directions, while being guided in the up and down direction by the up and down sweeping blades 300, so that the airflow can pass smoothly, reducing additional collision resistance, reducing wind resistance and wind noise, reducing air volume loss, and increasing the blowing distance.

[0052] The upper and lower sweeping blades 300 can be positioned close to the grille strip 200 to ensure that the airflow flows vertically and is blown out at the last moment before leaving the air control panel frame 100. This prevents the airflow from deviating from its original vertical direction due to diffusion or collision with the frame wall when flowing through the air control panel frame 100.

[0053] The left and right sweeping blades 400 can achieve a wide airflow diffusion range. Before the airflow reaches the upper and lower sweeping blades 300, the left and right sweeping blades 400 rotate to agitate the airflow, which can cause the airflow to deflect inside the air duct. This deflection is amplified after being accelerated by the outer upper and lower sweeping blades 300, so that it can cover a wider room area after being blown out of the air control panel frame 100.

[0054] Optionally, such as Figure 1 and Figure 3 As shown, the horizontally positioned upper and lower sweeping blades 300 are flush with the corresponding grille bars 200.

[0055] The upper and lower sweeping blades 300 are flush with the grille strip 200 to prevent the high-speed airflow from rushing towards the grille strip 200 and hitting its edge or windward side when the upper and lower sweeping blades 300 are slightly higher or lower than the grille strip 200, thereby preventing increased wind resistance and significant wind noise.

[0056] Specifically, when the airflow encounters the horizontally extending upper and lower sweeping blades 300 within the air control panel frame 100, the upper and lower sweeping blades 300 split the airflow in two: one part flows above the upper and lower sweeping blades 300, and the other part flows below. Because the front end of the upper and lower sweeping blades 300 is in close contact with the grille bar 200, the airflow after being split by the upper and lower sweeping blades 300 can be guided precisely to the gaps above and below the grille bar 200. This allows the airflow to be accurately distributed to the air outlets in the upper and lower gaps, preventing the airflow from directly impacting the back of the grille bar 200. This allows the airflow to smoothly bypass the grille bar 200 and flow out, maintaining a laminar flow state, reducing wind resistance, minimizing airflow loss, and increasing the air delivery distance.

[0057] The grille strip 200 is flush with the horizontally positioned upper and lower sweeping blades 300, which prevents the upper and lower sweeping blades 300 from stopping in the gap between adjacent grille strips 200, and prevents at least part of the gap between two adjacent grille strips 200 from being blocked, thereby preventing a significant reduction in air volume and a significant increase in wind noise.

[0058] The flush upper and lower sweeping blades 300 and the corresponding grille strips 200 ensure that the gaps between any two adjacent grille strips 200 are unobstructed, with no object blocking the airflow through the gaps. This ensures that the effective air outlet cross-sectional area of ​​the air control panel frame 100 reaches its maximum in the horizontal air supply mode, thereby obtaining the maximum air volume.

[0059] When the upper and lower sweeping blades 300 are flush with the grille strips 200, the upper and lower sweeping blades 300 will be blocked by the corresponding grille strips 200 when viewed from the front.

[0060] This reduces visual clutter, making the air vent side 120 look like a simple grille instead of a jumble of parts, giving the air control panel assembly a cleaner and more upscale appearance.

[0061] The flush alignment of the upper and lower sweeping blades 300 with the grille strips 200 allows the upper and lower sweeping blades 300 and the grille strips 200 to jointly form a longer guide surface in the front-to-back direction, that is, from the air inlet side 110 to the air outlet side 120. The extended guide surface enhances the Coanda effect, allowing the airflow to flow more stably in the predetermined direction, thereby throwing the cold air higher and farther, avoiding direct blowing on people, and making the hot air lower and more compact.

[0062] Optionally, such as Figure 3 and Figure 4 As shown, the lower front surface of the horizontally positioned upper and lower sweeping blades 300 is tilted upwards. This prevents the airflow from being blown out in a concentrated jet form, causing discomfort to the user, when it flows between the lower surfaces of two adjacent upper and lower sweeping blades 300. The upward tilt of the lower front surface of the upper and lower sweeping blades, specifically the side of the upper and lower sweeping blades 300 closest to the grille bar 200, means that as the airflow leaves the upper and lower sweeping blades 300, the cross-sectional area of ​​the flow channel gradually increases. This means the airflow passes through an expanded channel, slightly reducing its velocity and weakening its constrictive nature. This allows the airflow to disperse, reducing the pressure sensation on the skin and providing a gentler breeze for the user.

[0063] Furthermore, when the lower surface of the front end of the upper and lower sweeping blades 300 is tilted upward, the airflow flowing over the lower surface will try to deflect upward along this slope. This upward deflected airflow will converge and mix with the still air outside behind the grille strip 200, so that the user feels a disordered but gentle breeze, rather than a direct wind.

[0064] Even though the 300° sweeping blades are horizontal overall, this local upward tilt angle actually gives the lower airflow a small upward velocity component. This causes the cool air blowing towards the human body to blow slightly upward, with a parabolic airflow trajectory, which is conducive to the natural sinking of the cool air and enhances the gentle, non-direct blowing comfort.

[0065] Optionally, such as Figure 3 and Figure 4 As shown, the front ends of two adjacent upper and lower sweeping blades 300 in a horizontal state gradually become thinner and move away from each other along the direction from the air inlet side 110 to the air outlet side 120.

[0066] The tips of two adjacent sweeping blades gradually thin out. Specifically, the lower surface of the tip of one of the two adjacent sweeping blades tilts upward, while the upper surface of the tip of the lower sweeping blade 300 tilts downward, creating a funnel-shaped air outlet channel between the two adjacent upper and lower sweeping blades 300. This further enhances the gentle airflow effect.

[0067] Because the two vertical sweeping blades 300 are tilted to the upper and lower sides respectively, the airflow can be symmetrically diffused in both directions, ensuring that the wind is evenly spread in the vertical direction. This makes the airflow more uniform, so that users feel the same wind whether they are at a high or low position, and also prevents dead zones in the airflow.

[0068] This also prevents low-frequency noise from being generated when airflow rushes directly into a large room from a narrow duct.

[0069] By allowing the airflow to transition more smoothly and the sound wave energy to be released gently, the noise of the airflow can be significantly reduced while maintaining a large air volume, making the air conditioner sound quieter.

[0070] Optionally, such as Figure 4 As shown, the distal surface of the grid strip 200 is curved. According to the Coanda effect, high-speed airflow tends to flow along curved surfaces. When airflow rushes out from the gap between two adjacent grid strips 200, if the surface of the grid strip 200 is a flat right angle, the airflow will be ejected straight out, with a limited diffusion angle.

[0071] The outermost surface of the grille bar 200 in this application is arc-shaped. When the airflow leaves the gap, it will deflect and spread along this arc-shaped surface to the upper and lower sides, further expanding the air outlet channel and further improving the softness and uniformity of the airflow, so that the airflow can cover a wider vertical area.

[0072] The curved surface allows airflow to slide smoothly off the grille bar 200. This smooth sliding process greatly reduces the friction and impact between the airflow and the surface of the grille bar 200, making the exhaust sound more muffled and quiet, and reducing sharp noise.

[0073] The curved surface of the grille strip 200 has no sharp corners, so users will not cut their hands when wiping or accidentally touching the grille strip 200, making it safer.

[0074] The 200mm grille bar has a high surface tension due to its curved shape, making it difficult for condensation droplets to adhere. They are more likely to slide off or be carried away by the wind and evaporate, preventing water dripping and mold growth at the air outlet.

[0075] Optionally, such as Figure 3 As shown, the first sweeping blade has multiple through holes 410 arranged in an array.

[0076] In this way, each through-hole 410 can become an independent micro-air duct. When a large airflow rushes towards the left and right sweeping blades 400, it is forced to pass through these densely packed small through-holes 410. The originally whole airflow is cut into multiple micro-airflows by the array of through-holes 410.

[0077] The more through holes 410 there are, and the smaller the diameter of the through holes 410, the more parts can be cut, which reduces the impact of the wind, makes the blown air softer, and reduces the noise generated by the blowing.

[0078] Furthermore, when the left and right sweeping blades 400 oscillate, the airflow can directly pass through the through-hole 410, greatly reducing the air resistance when the left and right sweeping blades 400 oscillate. This makes the sweeping motion smoother and more fluid, extending the lifespan of the left and right sweeping blades 400.

[0079] Optionally, such as Figure 1 and Figure 2 As shown, there are at least two upper and lower sweeping blades 300, and each upper and lower sweeping blade 300 is arranged at intervals in the vertical direction. The air control panel assembly also includes a first drive structure 500 and an upper and lower sweeping link 600. The upper and lower sweeping link 600 is connected to at least two upper and lower sweeping blades 300, and the first drive structure 500 is drivenly connected to one of the at least two upper and lower sweeping blades 300.

[0080] The vertical sweeping linkage 600 can extend in the vertical direction. The first drive structure 500 may include a drive motor capable of driving one of at least two vertical sweeping blades 300 to rotate, thereby driving the remaining vertical sweeping blades 300 to rotate simultaneously via the vertical sweeping linkage 600. When the air outlet is closed, i.e., when the gap between two adjacent grille bars 200 is covered to prevent dust, the vertical sweeping linkage 600 ensures that all vertical sweeping blades 300 are pressed together simultaneously, resulting in better sealing and preventing dust from entering.

[0081] A single drive motor is sufficient to rotate all the upper and lower sweeping blades 300° synchronously. In mass production of control panel components, the cost savings from reducing the number of motors are substantial, including material costs, installation costs, and PCB board area, while also saving installation space.

[0082] Furthermore, the program only needs to send commands to this one drive motor, and all the upper and lower sweeping blades 300 will rotate synchronously. This eliminates the need for complex code to coordinate multiple drive motors, avoiding potential logical conflicts that might arise from controlling multiple drive motors.

[0083] Optionally, there are at least two left and right sweeping blades 400, and each left and right sweeping blade 400 is arranged at intervals along the left and right direction. The air control panel assembly also includes a second drive structure and a left and right sweeping linkage 700, the left and right sweeping linkage 700 being connected to at least two left and right sweeping blades 400, and the second drive structure being drivenly connected to one of the at least two left and right sweeping blades 400.

[0084] The left and right sweeping linkages 700 can extend in the left and right direction. The second drive structure may include a motor capable of driving at least one of the two left and right sweeping blades 400 to rotate, thereby driving the remaining left and right sweeping blades 400 to rotate simultaneously via the left and right sweeping linkages 700.

[0085] In this way, only one motor is needed to make all the left and right sweeping blades 400 rotate synchronously, saving costs and installation space. Furthermore, the program only needs to send commands to this one motor, and all the left and right sweeping blades 400 will rotate synchronously. There is no need for complex code to coordinate the operation of multiple motors, avoiding potential logical conflicts that may occur with multi-motor control.

[0086] Optionally, the upper and lower sweeping linkage 600 is engaged with the portions of at least two upper and lower sweeping blades 300 near the air inlet side 110. When the width direction of the left and right sweeping blades 400 is parallel to the front and rear direction, the left and right sweeping blades 400 are flush with the corresponding upper and lower sweeping linkage 600.

[0087] The upper and lower air sweeping linkage 600 is engaged with the upper and lower air sweeping blades 300 on the side near the air inlet side 110, so that the upper and lower air sweeping linkage 600 is located deep in the air control panel frame 100.

[0088] Regardless of whether the upper and lower sweeping blades 300 are running, they can block at least part of the upper and lower sweeping linkage 600, making the blocked part invisible to the user.

[0089] When the air control panel assembly is closed, the upper and lower sweeping blades 300 need to flip to tightly close the gap between them and the adjacent grille strips 200. The upper and lower sweeping linkage 600 is engaged with the rear side of the upper and lower sweeping blades 300, which prevents the upper and lower sweeping linkage 600 from hitting the outer grille strips 200 when closed, thereby preventing the upper and lower sweeping blades 300 from not closing tightly.

[0090] By aligning the left and right sweeping blades 400 and the upper and lower sweeping linkages 600, the upper and lower sweeping linkages 600 can cover the left and right sweeping blades 400, hiding the left and right sweeping blades 400 inside the air control panel frame 100, reducing the clutter of components and improving the simplicity of the air control panel assembly.

[0091] Optionally, the horizontally positioned vertical sweeping blades 300 are flush with the corresponding horizontal sweeping links 700. The horizontal sweeping links 700 are engaged with the portions of at least two horizontal sweeping blades 400 near the air inlet side 110.

[0092] The left and right air sweeping linkage 700 is engaged with the left and right air sweeping blades 400 on the side near the air inlet side 110, so that the left and right air sweeping linkage 700 is located deeper in the air control panel frame 100.

[0093] Regardless of whether the left and right sweeping blades 400 are running, the left and right sweeping blades 400 can block at least part of the left and right sweeping linkages 700, and the blocked part can be not seen by the user.

[0094] By aligning the upper and lower sweeping blades 300 and the left and right sweeping linkages 700, the left and right sweeping blades 400 can cover the left and right sweeping linkages 700, hiding the left and right sweeping linkages 700 within the air control panel frame 100, further reducing the clutter of components and enhancing the simplicity of the air control panel assembly.

[0095] Optionally, such as Figure 1 As shown, the air control panel assembly also includes a decorative frame 130, with at least two grille strips 200 disposed on the decorative frame 130. The decorative frame 130 is disposed on the front side of the air outlet side 120 and is snapped into the air control panel frame 100.

[0096] By installing each grille strip 200 on the decorative frame 130, multiple grille strips 200 can be installed simultaneously on the front side of the air control panel frame 100. When multiple grille strips 200 need to be removed for maintenance, only the decorative frame 130 needs to be removed, which is convenient and quick.

[0097] Optionally, such as Figure 1 As shown, the first direction is the up-down direction, and the second direction is the left-right direction; the first sweeping blade is the up-down sweeping blade 300, and the second sweeping blade is the left-right sweeping blade 400. Along the direction from the air inlet side 110 to the air outlet side 120, the up-down sweeping blade 300, the left-right sweeping blade 400, and the grille strip 200 are arranged in sequence.

[0098] In this way, the airflow will first pass through the upper and lower sweeping blades 300, and under the rotation of the upper and lower sweeping blades 300, it will flow towards the left and right sweeping blades 400 and have a component of flow in the upper and lower direction. Then it will flow to the left and right sweeping blades 400. Under the rotation of the left and right sweeping blades 400, the airflow will be dispersed into multiple streams. Finally, the airflow will be further divided by the cutting of the grid strips 200, which will improve the flexibility of the airflow.

[0099] Based on the same inventive concept, referring to Figure 1This application also provides a ducted air conditioner, which includes all the advantages of the above-mentioned air control panel assembly, and will not be described in detail here.

[0100] Optionally, such as Figure 1 As shown, the air control panel assembly also includes a mounting frame 140, and the duct unit also includes a body, with the mounting frame 140 fitted around the body.

[0101] The beneficial technical effects of the technical solutions provided in this application include: The first and second sweeping blades control airflow in the left-right and up-down directions respectively, and are concealed behind the grille strip 200, achieving three-dimensional concealed airflow control. By positioning both the first and second sweeping blades behind the grille strip 200, the airflow is segmented upon passing through them, preventing cold air from blowing directly on the user and causing discomfort, thus achieving a windless feel. Multiple grille strips 200 located on the air outlet side 120 are arranged in a straight line along the second direction, maintaining parallelism with the first sweeping blades inside the airflow control frame. Each grille strip 200 has the same spacing as the second sweeping blade, resulting in more precise and efficient airflow control.

[0102] The airflow can slide laterally along the surface of the vertically sweeping blades 300 extending in the left and right directions, and at the same time be guided in the vertical direction by the vertically sweeping blades 300, so that the airflow can pass smoothly, reduce additional collision resistance, reduce wind resistance and wind noise, reduce air volume loss, and increase the blowing distance.

[0103] The upper and lower sweeping blades 300 are flush with the grille strip 200 to prevent the high-speed airflow from rushing towards the grille strip 200 and hitting its edge or windward side when the upper and lower sweeping blades 300 are slightly higher or lower than the grille strip 200, thereby preventing increased wind resistance and significant wind noise.

[0104] The flush upper and lower sweeping blades 300 and the corresponding grille strips 200 ensure that the gaps between any two adjacent grille strips 200 are unobstructed, with no object blocking the airflow through the gaps. This ensures that the effective air outlet cross-sectional area of ​​the air control panel frame 100 reaches its maximum in the horizontal air supply mode, thereby obtaining the maximum air volume.

[0105] By aligning the left and right sweeping blades 400 and the upper and lower sweeping linkages 600, the upper and lower sweeping linkages 600 can cover the left and right sweeping blades 400, hiding the left and right sweeping blades 400 inside the air control panel frame 100, reducing the clutter of components and improving the simplicity of the air control panel assembly.

[0108] The above description is only a partial implementation of this application. It should be noted that for those skilled in the art, other similar implementation methods based on the technical concept of this application, without departing from the technical concept of this application, also fall within the protection scope of the embodiments of this application.
