All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0025] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0027] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0028] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0029] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0031] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0032] Hereinafter, with reference to the accompanying drawings, a face mask assembly 10 according to a first aspect of the present invention will be described.

[0033] Reference Figure 1 and Figure 2 The mask assembly 10 includes a panel 1 and a decorative cover 2. The panel 1 has a functional area 11, and one side of the panel 1 in the thickness direction F3 is the outer side. The decorative cover 2 is located on the outer side of the panel 1 and can slide relative to the panel 1 between a first position P1 and a second position P2. When the decorative cover 2 is in one of the first position P1 and the second position P2, it covers the functional area 11, and when it is in the other position, it avoids the functional area 11 so that the functional area 11 is exposed.

[0034] The mask assembly 10 can be installed on relevant equipment to expose or cover a specific area to achieve a specific function. The functional area 11 is an area on the panel 1 with a specific function, such as a voice area, an operation area, or a placement area. The movement of the decorative cover 2 can control its exposure or obstruction.

[0035] For example, the face shield assembly 10 can be disposed on the portable display device 1000, and the functional area 11 can be an operation area, a speaker area 11a, a remote control placement area 11b, etc. The decorative cover 2 can expose or cover the functional area 11 by sliding relative to the panel 1 between a first position P1 and a second position P2. For example, when the decorative cover 2 is in the first position P1, it covers the functional area 11, which can provide a certain degree of protection for the functional area 11 of the panel 1, preventing damage from external factors such as dust, moisture, and collisions. For example, during the transportation of the portable display device 1000, it can reduce the accidental touching or bumping of the functional area 11 during transportation, protecting the components of the functional area 11 from damage. When the decorative cover 2 is in the second position P2, it avoids the functional area 11 so that the functional area 11 can be exposed to perform its function, or facilitates the operation and removal of the device with the functional area 11, etc. Alternatively, the decorative cover 2 can cover the functional area 11 when it is in the second position P2, and avoid the functional area 11 when it is in the first position P1 so that the functional area 11 is exposed.

[0036] Since the decorative cover 2 is located on the outside of the panel 1 and can flexibly switch between covering and revealing the functional area 11 of the panel 1 through sliding movement, the structure is relatively compact and does not occupy too much space inside the panel 1. At the same time, the translational movement method reduces interference between moving parts compared to setting a rotation or flipping structure. When switching the state of covering and revealing the functional area 11, the translational movement method does not require a lot of space, improving space utilization and making the entire mask assembly 10 easy to use and portable.

[0037] Reference Figure 3 and Figure 4 The mask assembly 10 also includes a driver 3 and a sliding stabilization auxiliary mechanism 4. The driver 3 includes an elastic element 31, which is disposed between the decorative cover 2 and the panel 1, and the elastic element 31 provides a unidirectional elastic driving force to the decorative cover 2 to move from a first position P1 to a second position P2. The sliding stabilization auxiliary mechanism 4 is disposed between the decorative cover 2 and the panel 1, and includes a buffering mechanism 41 for buffering the decorative cover 2 to stabilize the sliding speed of the decorative cover 2 and / or a guiding mechanism 42 for guiding the decorative cover 2 to stabilize the sliding trajectory of the decorative cover 2, so as to stabilize the sliding of the decorative cover 2 relative to the panel 1.

[0038] The elastic element 31 provides a unidirectional elastic driving force for the decorative cover 2 to move from the first position P1 to the second position P2. This unidirectional elastic driving force means that the direction of the driving force generated by the elastic element 31 is fixed; that is, the direction of the driving force of the elastic element 31 is the direction in which the decorative cover 2 moves from the first position P1 to the second position P2. The elastic driving force will not undergo a sudden change in sliding speed due to a change in direction, thereby improving the sliding stability of the decorative cover 2. The structural form of the elastic element 31 is not limited. For example, the elastic element 31 can be a spring (coil spring, torsion spring, etc.), a coil spring 311, elastic rubber, etc.

[0039] The sliding stabilization auxiliary mechanism 4 includes at least one of a buffer mechanism 41 for cushioning the decorative cover 2 to stabilize its sliding speed and a guide mechanism 42 for guiding the decorative cover 2 to stabilize its sliding trajectory. This ensures stable sliding of the decorative cover 2 relative to the panel 1, meaning that the sliding speed and / or sliding trajectory of the decorative cover 2 are basically stable during its sliding process. When the sliding trajectory is stable, the decorative cover 2 is less prone to wobbling, deviation, or jamming during sliding. When the sliding speed is stable, the sliding speed of the decorative cover 2 is relatively stable, and the speed is less prone to fluctuation, reducing the risk of sliding deceleration or excessive speed. For example, the guide mechanism 42 can be a guide rail, guide groove, or other guiding mechanism. The buffer mechanism 41 can be an inertial buffer mechanism such as a sprocket chain, gear rack, or connecting rod.

[0040] In the above technical solution, by setting the driver 3 and the sliding stabilizing auxiliary mechanism 4, the decorative cover 2 can obtain driving force. The user does not need to apply additional force, and the decorative cover 2 can automatically complete the translational movement from the first position P1 to the second position P2, making the operation easy and effortless. The driver 3 provides unidirectional driving force, so that the driving force will not undergo sudden changes due to reversal during the movement, thereby making the decorative cover 2 easy to move at a stable speed. The sliding stabilizing auxiliary mechanism 4 is used to make the decorative cover 2 slide stably relative to the panel 1, making the movement of the decorative cover 2 more stable and gentle.

[0041] In some related technologies, decorative covers achieve bidirectional reciprocating sliding manually using a two-way elastic bar. Specifically, when the decorative cover slides back and forth relative to the main structure in a specific area, one end of the elastic bar is set on the decorative cover, and the other end is set on the main structure. Manually dragging the decorative cover causes the elastic bar to deform under pressure, generating elastic force. After the decorative cover slides a certain distance, the elastic force of the elastic bar changes direction, driving the decorative cover to continue sliding. However, when the elastic force of the elastic bar changes direction and provides driving force to the decorative cover, it can cause the decorative cover to slide too fast momentarily, making it prone to impact and damage after it reaches its destination. This application, by setting a driver 3 and a sliding stabilizing auxiliary mechanism 4, enables the decorative cover 2 to move stably, thus solving the aforementioned technical problems.

[0042] Reference Figure 1 and Figure 2 In some embodiments, the panel 1 is vertically arranged, the functional area 11 is located at the lower part of the panel 1, the decorative cover 2 slides relative to the panel 1 in the vertical direction, the decorative cover 2 moves downward to the first position P1 to cover the functional area 11, and the elastic member 31 provides the decorative cover 2 with a unidirectional elastic driving force for moving upward from bottom to top.

[0043] In the above technical solution, panel 1 is vertically positioned, and decorative cover 2 moves downward to a first position P1 to cover functional area 11. When functional area 11 needs to be used, decorative cover 2 moves upward to a second position P2 to avoid functional area 11, thereby exposing functional area 11 to achieve its function. Elastic member 31 provides a unidirectional elastic driving force to decorative cover 2 from bottom to top, so that decorative cover 2 can automatically move upward when functional area 11 needs to be exposed. The user does not need to manually overcome the gravity of decorative cover 2, making operation simple and effortless. Of course, it is not limited to this; functional area 11 can also be located on the upper part of panel 1.

[0044] Reference Figure 1 and Figure 2 In some embodiments, the functional area 11 includes at least one of a speaker area 11a and a remote control placement area 11b.

[0045] In the above technical solution, when the decorative cover 2 blocks the functional area 11 at the first position P1, it can protect the speaker and the remote control in the remote control placement area 11b, prevent dust and debris from entering the speaker area 11a and affecting the sound quality, reduce the possibility of the remote control being bumped, scratched or lost, and make the appearance of the panel 1 cleaner; when the decorative cover 2 avoids the functional area 11 at the second position P2, the speaker area 11a and the remote control placement area 11b can be exposed, so that the sound emitted by the speaker will not be blocked by the decorative cover 2, and it is convenient to take out the remote control.

[0046] Reference Figure 5 In some embodiments, the elastic element 31 is a coil spring 311, and the driver 3 includes a coil spring seat 32 disposed on the panel 1. The coil spring 311 is wound around the coil spring seat 32, and one end of the coil spring 311 extends out of the coil spring seat 32 and is connected to the decorative cover 2. Both the coil spring seat 32 and the coil spring 311 are covered by the decorative cover 2.

[0047] In the above technical solution, the coil spring 311 can provide a relatively continuous and uniform elastic force during the movement of the decorative cover 2. Compared with some other types of elastic elements 31 (such as spring bars), there will be no sudden change in force, which makes the movement of the decorative cover 2 more stable when sliding up and down, reduces the possibility of excessive speed due to unstable elastic force, and improves the stability of the translational movement of the decorative cover 2.

[0048] In addition, the coil spring 311 has a compact overall structure and does not take up too much space, which is conducive to adapting to various shapes and structures of panels 1 and decorative covers 2. In the process of providing elastic force, the coil spring 311 is not prone to jamming due to its own structural problems or friction with other parts, and the coil spring 311 is not easy to wear, which improves the movement reliability of the decorative cover 2.

[0049] In the above technical solution, both the coil spring seat 32 and the coil spring 311 are covered by the decorative cover 2. That is, from the outside, the coil spring 311 and its mounting structure will not be exposed on the panel 1, making the overall appearance of the panel 1 neater.

[0050] Reference Figure 4 In some embodiments, the two ends of the decorative cover 2 in the translational direction of the decorative cover 2 are respectively the first end 21 and the second end 22, and the direction from the first end 21 to the second end 22 is the direction from the first position P1 to the second position P2, combined with Figure 5 When the decorative cover 2 is in the first position P1, the coil spring seat 32 is opposite to the second end 22, and the two ends are engaged. Figure 6 When the decorative cover 2 is in the second position P2, the coil spring seat 32 is opposite to the first end 21, and the end of the coil spring 311 extending out of the coil spring seat 32 is connected to the first end 21.

[0051] In the above technical solution, one end of the coil spring 311 extending out of the coil spring seat 32 is connected to the first end 21, thereby enabling the decorative cover 2 to have a large movement distance in the translational direction, so as to realize the function of the decorative cover 2 to switch the state of the functional area 11 to cover and reveal.

[0052] In the above technical solution, when the decorative cover 2 is in the first position P1, the coil spring seat 32 is opposite to the second end 22. When the decorative cover 2 is in the second position P2, the coil spring seat 32 is opposite to the first end 21. This makes it easy for the decorative cover 2 to cover the coil spring seat 32 and the coil spring 311. Whether the decorative cover 2 is in the first position P1 or the second position P2, or during the movement, the coil spring seat 32 and the coil spring 311 are covered by the decorative cover 2, so that the coil spring 311 and its mounting structure will not be exposed. Moreover, the movement distance of the decorative cover 2 is relatively large, which can cover and expose a larger area, so that a larger area can be used as the functional area 11, making the setting of the functional area 11 more flexible.

[0053] Reference Figure 8 In some embodiments, the decorative cover 2 includes a support frame 23 disposed on the side of the decorative cover 2 facing the panel 1, combined with Figure 5 The end of the coil spring 311 extending out of the coil spring seat 32 is formed into a hook shape, which flips from the edge of the support frame 23 to the side of the support frame 23 opposite to the panel 1 and hooks with the support frame 23.

[0054] In the above technical solution, the hook end of the coil spring 311 directly hooks with the support frame 23, eliminating the need for additional connecting parts (such as bolts or clips), thus reducing the number of parts. Furthermore, the direct hook-on of the hook end to the support frame 23 simplifies assembly; the connection is completed simply by wrapping the hook end of the coil spring 311 around the edge of the support frame 23, requiring no additional tools and facilitating production assembly. Of course, this application is not limited to this; for example, the end of the coil spring 311 extending from the coil spring seat 32 can also be connected to the decorative cover 2 through methods such as bonding, threaded connection, snap-fit, or snap-fit ​​connection, which will not be elaborated here.

[0055] Reference Figure 5 and Figure 6 In some embodiments, the driver 3 includes a plurality of elastic elements 31 arranged in parallel. The translation direction of the decorative cover 2 is the width direction of the decorative cover 2. The plurality of elastic elements 31 are symmetrically distributed on both sides of the center line L of the decorative cover 2. The center line L is a straight line located at the center position in the length direction of the decorative cover 2 and extending along the width direction of the decorative cover 2. The parallel arrangement of the plurality of elastic elements 31 does not mean that they are simply arranged side by side, but rather that the plurality of elastic elements 3 occupy similar spatial positions and are interconnected and synchronized in terms of force, jointly undertaking the task of providing driving force, thereby improving the driving capability and functional stability of the elastic elements 3.

[0056] In the above technical solution, multiple elastic elements 31 are symmetrically distributed on both sides of the center line L of the decorative cover 2. When the decorative cover 2 slides along its width, each elastic element 31 can share the force, making the force on the decorative cover 2 more uniform along its length. Compared with a single elastic element 31, this reduces problems such as tilting, jamming, or uneven movement of the decorative cover 2, ensuring that the decorative cover 2 can slide smoothly along its width, thus improving the reliability and stability of the mask assembly 10.

[0057] Reference Figure 5 and Figure 6 In some embodiments, the sliding stabilization auxiliary mechanism 4 includes a buffer mechanism 41, which includes at least one of a gear and rack mechanism 41a, a roller screw mechanism, and a worm gear mechanism. Thus, the buffer mechanism 41 improves the stability of the sliding speed, smooths speed fluctuations, and reduces the impact of excessively fast sliding of the decorative cover 2, which could damage the sliding structure or cause jamming, resulting in a smoother and gentler sliding of the decorative cover 2. Furthermore, the buffer mechanism 41 is robust, durable, and wear-resistant, which can extend the service life of the sliding stabilization auxiliary mechanism 4.

[0058] Reference Figure 5 and Figure 6In some embodiments, the buffer mechanism 41 is a gear and rack mechanism 41a and includes a gear 411 and a rack 412. The rack 412 is located on the side of the decorative cover 2 facing the panel 1 and extends along the translational direction of the decorative cover 2. The gear 411 is located on the panel 1 and meshes with the rack 412.

[0059] In the above technical solution, the buffer mechanism 41 includes a gear 411 and a rack 412. The meshing transmission of the gear 411 and the rack 412 has high precision and stability, thereby reducing the shaking, swaying and jamming of the decorative cover 2 during translation, making the movement of the decorative cover 2 smoother and more stable. The rack 412 is located on the side of the decorative cover 2 facing the panel 1, so that the decorative cover 2 covers the rack 412, making the rack 412 not exposed, improving the appearance of the decorative cover 2, and the decorative cover 2 provides protection for the rack 412, making the rack 412 less prone to dust accumulation and jamming.

[0060] In the above technical solution, the buffer mechanism 41 includes a gear 411 and a rack 412. The buffering force can be adjusted by adjusting the meshing tightness and changing the rotational resistance at the shaft of the gear 411. The buffering force adjustment can be selected according to different usage scenarios and needs, improving the matching between the resistance of the buffer mechanism 41 and the driving force of the driver 3, and increasing the adaptability of the mask assembly 10 to different working conditions.

[0061] Reference Figure 5 and Figure 6 In some embodiments, there are two rack and pinion mechanisms 41a arranged in parallel. The translation direction of the decorative cover 2 is the width direction of the decorative cover 2. The two rack and pinion mechanisms 41a are symmetrically distributed on both sides of the center line L of the decorative cover 2. The center line L is a straight line located at the center position in the length direction of the decorative cover 2 and extending along the width direction of the decorative cover 2.

[0062] For example, refer to Figure 5 and Figure 6 The gear and rack mechanism 41a consists of two parallel racks, with two racks 412 and two gears 411. The two racks 412 are arranged in parallel, and the two gears 411 are located between the two racks 412 or on opposite sides of the racks 412. This creates a clamping fit along the length of the decorative cover 2, resulting in a tighter connection between the decorative cover 2 and the panel 1, reducing the likelihood of detachment or falling off, minimizing wobbling of the decorative cover 2 along its length, and improving the reliability of the mask assembly 10's movement.

[0063] In the above technical solution, the two gear and rack mechanisms 41a are symmetrically distributed on both sides of the center line L of the decorative cover 2, which makes the force on the decorative cover 2 more uniform in the length direction. This reduces problems such as tilting, jamming or unsmooth movement of the decorative cover 2 caused by asynchronous movement at both ends of the length direction due to excessive length. It ensures that the decorative cover 2 can slide smoothly along the width direction of the decorative cover 2, and improves the reliability and stability of the mask assembly 10.

[0064] Reference Figure 5 and Figure 6 In some embodiments, there are two elastic elements 31, which are spaced apart along the length of the decorative cover 2 and symmetrically distributed on both sides of the center line L of the decorative cover 2, and two gear rack mechanisms 41a are located between the two elastic elements 31 along the length of the decorative cover 2.

[0065] In the above technical solution, there are two elastic elements 31 symmetrically distributed on both sides of the center line L of the decorative cover 2, which can make the force on the decorative cover 2 more uniform during translation. Compared with single-sided drive, dual-sided drive can reduce the skewing or jamming of the decorative cover 2 caused by uneven force.

[0066] In the above technical solution, the two gear and rack mechanisms 41a are located between the two elastic members 31 along the length of the decorative cover 2, which allows the gear and rack mechanisms 41a to better control the movement of the decorative cover 2. During the movement of the decorative cover 2, the driving force provided by the elastic members 31 on both sides causes the decorative cover 2 to move, while the gear and rack mechanism 41a in the middle can provide inertial buffering, making the movement speed of the decorative cover 2 more uniform and reducing the occurrence of overspeeding caused by excessive driving force.

[0067] For example, the rack and pinion mechanism 41a is located between the two elastic elements 31, and there are two rack and pinion mechanisms 41a arranged at intervals along the transverse direction F1. Thus, the two rack and pinion mechanisms 41a and the two elastic elements 31 form a matching mechanism of driving force and resistance. The rack and pinion mechanism 41a better balances the forces acting on the elastic elements 31 on both sides. Specifically, it can prevent instability in the movement of the decorative cover 2 caused by differences in the performance of the elastic elements 31 on both sides or uneven force distribution. For example, if the unidirectional driving forces provided by the two elastic elements 31 differ in magnitude, the buffering force of the rack and pinion mechanism 41a on the corresponding side can be adjusted to balance this difference, thereby reducing the skewing or jamming of the decorative cover 2 caused by uneven force distribution.

[0068] Reference Figure 7 and Figure 8In some embodiments, the translation direction of the decorative cover 2 is longitudinal (F2), and the direction perpendicular to longitudinal (F2) within the motion sweeping plane S1 of the decorative cover 2 is transverse (F1). The sliding stabilization auxiliary mechanism 4 includes a guide mechanism 42. The decorative cover 2 and the panel 1 cooperate through the guide mechanism 42 to guide the decorative cover 2 to translate relative to the panel 1 along longitudinal (F2) and to prevent the decorative cover 2 from moving relative to the panel 1 along transverse (F1) and perpendicular to the motion sweeping plane S1. The motion sweeping plane S1 of the decorative cover 2 refers to the plane swept by a certain edge (e.g., the lower edge) of the decorative cover 2. For example, the motion sweeping plane S1 can also be understood as a plane perpendicular to the inward and outward directions of the panel 1.

[0069] In the above technical solution, the decorative cover 2 and the panel 1 cooperate through the guide mechanism 42, so that the guide mechanism 42 provides stable support and guidance for the sliding of the decorative cover 2, reducing the possibility of movement deviation due to external factors (such as vibration and collision). The guide mechanism 42 hinders the movement of the decorative cover 2 relative to the panel 1 in the direction of the horizontal F1 and the vertical motion sweeping plane S1, thereby limiting the degree of freedom of the decorative cover 2, making it less likely for the decorative cover 2 to wobble in other directions when it translates along the longitudinal F2, thus improving the stability of the decorative cover 2 when it translates along the longitudinal F2.

[0070] In the embodiments of this application, the type of guide mechanism 42 is not limited. For example, the guide mechanism 42 can be a guide rail slider type guide mechanism, a guide column guide sleeve type guide mechanism, etc.

[0071] For example, refer to Figure 7 , Figure 8 and Figure 9 In some embodiments, the guide mechanism 42 includes a first guide mechanism 421, which includes a sliding block 4211 and a first slide rail 4212. The two sides of the panel 1 on the horizontal direction F1 respectively form the first slide rail 4212. The first slide rail 4212 extends along the longitudinal direction F2. The decorative cover 2 is provided with a first block 4211 at both ends on the horizontal direction F1. The first block 4211 extends from the corresponding side edge of the panel 1 to the inside of the thickness direction F3 of the panel 1 and cooperates with the first slide rail 4212 on the corresponding side.

[0072] In the above technical solution, the first slide rail 4212 is directly formed by the two side edges of the horizontal F1 of the panel 1, thereby eliminating the need for additional design and manufacturing of independent slide rail components, reducing the number of parts, simplifying the overall structure, facilitating assembly, improving production efficiency, and reducing production costs.

[0073] In the above technical solution, the first slider 4211 extends from the corresponding side edge of the panel 1 to the inner side of the panel 1 and cooperates with the first slide rail 4212 on the corresponding side, making the movable connection between the two sides of the horizontal F1 of the panel 1 and the decorative cover 2 more secure, which can reduce the situation where the decorative cover 2 detaches or falls off from the two sides of the horizontal F1 of the panel 1; the first slide rail 4212 is provided on both sides of the horizontal F1 of the panel 1, and the two ends of the decorative cover 2 cooperate with the first slide rail 4212 on both sides through the first slider 4211, forming a double-sided guide cooperation structure. The double-sided guide can better balance the force on the decorative cover 2 during the movement, reduce the problems of tilting and shaking of the decorative cover 2 caused by uneven force, and improve the stability and smoothness of the translation of the decorative cover 2 along the longitudinal F2.

[0074] Reference Figure 7 and Figure 8 In some embodiments, the guide mechanism 42 includes a second guide mechanism 422, which includes a second slider 4221 and a second slide rail 4222 that slide in a sliding engagement. The decorative cover 2 includes a support frame 23 disposed on the side of the decorative cover 2 facing the panel 1. The support frame 23 is provided with second slide rails 4222 at both ends along the transverse F1. The second slide rails 4222 extend along the longitudinal F2. The second slider 4221 is disposed on the panel 1. The second sliders 4221 are respectively disposed on both sides of the transverse F1 of the support frame 23. The second sliders 4221 on both sides cooperate with the second slide rails 4222 on the corresponding sides.

[0075] For example, such as Figure 7 and Figure 8 As shown, the decorative cover 2 has two support frames 23 on the side facing the panel 1. The two support frames 23 are spaced apart along the horizontal direction F1. The two sides of the horizontal direction F1 of the two support frames 23 form four second slide rails 4222. The panel 1 is provided with four second sliders 4221. The four second sliders 4221 cooperate with the second slide rails 4222 on the corresponding side.

[0076] In the above technical solution, a support frame 23 is provided on the side of the decorative cover 2 facing the panel 1, which makes the overall structure of the decorative cover 2 more stable. The support frame 23 can distribute the weight of the decorative cover 2 itself and the force generated during the movement, reducing the possibility of deformation or damage to the structure of the decorative cover 2. The support frame 23 is provided with second slide rails 4222 at both ends along the transverse F1. The second sliders 4221 on both sides cooperate with the second slide rails 4222 on the corresponding sides, which enhances the stability of the guide structure, reduces the shaking and displacement of the decorative cover 2, and improves the stability and smoothness of the translation of the decorative cover 2 along the longitudinal F2.

[0077] Reference Figure 7 , Figure 8 and Figure 9In some embodiments, the guide mechanism 42 includes a first guide mechanism 421 and a second guide mechanism 422. The first guide mechanism 421 includes a first slider 4211 and a first slide rail 4212 that slide in a sliding engagement. The two side edges of the panel 1 in the transverse direction F1 respectively form the first slide rail 4212. The first slide rail 4212 extends along the longitudinal direction F2. The decorative cover 2 is provided with first sliders 4211 at both ends in the transverse direction F1. The first sliders 4211 extend from the corresponding side edge of the panel 1 to the inner side of the panel 1 in the thickness direction F3 and are engaged with the first slide rail 4212 on the corresponding side. The slide rail 4212 is engaged; the second guide mechanism 422 includes a sliding second slider 4221 and a second slide rail 4222, the decorative cover 2 includes a support frame 23 on the side of the decorative cover 2 facing the panel 1, the support frame 23 is provided with second slide rails 4222 at both ends along the transverse F1, the second slide rails 4222 extend along the longitudinal F2, the second slider 4221 is provided on the panel 1, the second sliders 4221 are provided on both sides of the transverse F1 of the support frame 23, and the second sliders 4221 on both sides are engaged with the second slide rails 4222 on the corresponding sides.

[0078] In the above technical solution, a first guide mechanism 421 and a second guide mechanism 422 are simultaneously provided. The first guide mechanism 421 uses the two side edges of the panel 1 as the first slide rail 4212, which cooperates with the first sliders 4211 at both ends of the decorative cover 2. The second guide mechanism 422 uses the second slide rails 4222 at both ends of the support frame 23 to cooperate with the second sliders 4221 on the panel 1. The two sets of sliders and slide rails slide and cooperate respectively to realize the interlock between the panel 1 and the decorative cover 2, which enhances the connection strength between the panel 1 and the decorative cover 2, prevents the decorative cover 2 from separating from the panel 1 during movement, reduces the possibility of shaking, offset and jamming, and improves the stability and reliability of the entire movable connection structure.

[0079] Reference Figure 8 In some embodiments, the longitudinal direction F2 is the width direction of the decorative cover 2. The decorative cover 2 includes a support frame 23 disposed on the side of the decorative cover 2 facing the panel 1. There are two support frames 23 and they are spaced apart along the length direction of the decorative cover 2. The buffer mechanism 41 is located between the two support frames 23.

[0080] In the above technical solution, the arrangement of two support frames 23 spaced apart along the length of the decorative cover 2 enhances the structural strength of the decorative cover 2 in the length direction, enabling it to better maintain its shape and stability during movement and reducing deformation or damage to the decorative cover 2 due to excessive local stress. In the above technical solution, the buffer mechanism 41 is located between the two support frames 23, facilitating its centralized installation.

[0081] Reference Figure 8 and Figure 9In some embodiments, the mask assembly 10 further includes a locking mechanism 5, which is disposed between the decorative cover 2 and the panel 1 and can be switched between a locked state and an unlocked state. When the decorative cover 2 moves to the first position P1, the locking mechanism 5 can switch to the locked state to prevent the movement of the decorative cover 2.

[0082] In the embodiments of this application, the locking mechanism 5 is not limited in form, and can be a mechanical latch locking mechanism, an electromagnetic locking mechanism, a hydraulic or pneumatic locking mechanism, etc. For example, the decorative cover 2 has an upper end and a lower end in the translational direction, the elastic element 31 is a coil spring 311, and the locking mechanism 5 includes a latch 51 and a latch 52. The latch 51 is located at the upper end of the decorative cover 2, and the latch 52 includes a spring and a hook and is located in the middle of the panel 1. When the decorative cover 2 moves to the first position P1, the coil spring 311 is in its longest stretched state. Pressing the latch 51 inserts it into the latch 52 and it is hooked by the hook to present a locked state, preventing the decorative cover 2 from being driven upward by the driving force of the coil spring 311. Pressing the latch 51 again unlocks the latch 51 and releases the decorative cover 2. The decorative cover 2 is driven upward by the driving force of the coil spring 311 to the second position P2. Alternatively, the locking mechanism 5 can be a locking mechanism (i.e., the cooperation between the lock hole and the sliding pin) to switch between the locked and unlocked states.

[0083] In the above technical solution, the locking mechanism 5 switches to the locking state when the decorative cover 2 moves to the first position P1, which can prevent the movement of the decorative cover 2, so that the decorative cover 2 is stably in the first position P1, so as to stably block the functional area 11 for a long time, providing a certain protection for the functional area 11 of the panel 1 and preventing damage from external factors such as dust, moisture, and collision.

[0084] For example, the translation direction of the decorative cover 2 is vertical, and the elastic element 31 is a coil spring 311, which provides the decorative cover 2 with an upward driving force to overcome its own weight. Therefore, the design of the coil spring 311 should meet the following requirements: the calculated support weight of the coil spring should be greater than the structural safety calculated weight of the decorative cover 2, and the stress of the coil spring should not exceed the upper limit of stress corresponding to the design usage number. For example, the calculation results can be obtained by inputting variable parameters through existing calculation formulas. For example, inputting the structural weight of the decorative cover 2 can calculate the structural safety calculated weight of the decorative cover 2, and inputting the inner diameter, thickness, and width of the coil spring can calculate the calculated support weight of the spring, the spring stress, and other parameters, ensuring that the calculated support weight of the coil spring is greater than the structural safety calculated weight of the decorative cover 2 to meet the requirements. In addition, based on the required sliding stroke of the decorative cover 2, the minimum number of coils, the optimal number of coils, the maximum outer diameter, and other parameters of the coil spring can be calculated to meet the length requirements of the coil spring.
