Detailed Implementation

[0075] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0076] Currently, projection screen systems can be added to cars to enhance the entertainment and functional experience for passengers. Typically, the screen assembly is retractable and mounted on the vehicle's roof, unfolding when in use and retracting when not in use to minimize obstruction. Generally, the screen assembly moves along the trim panel to unfold or retract. Currently, the trim panel is a fixed, non-closable design. This design not only occupies a significant amount of interior space but also has obvious drawbacks; even when the projection screen is not in use, the trim panel cannot be closed, directly affecting the overall aesthetics of the car's interior.

[0077] For this purpose, please refer to Figures 1 to 4 This application provides a trim structure 100, which is applied to a curtain device (not shown) in a vehicle (not shown). Figure 1This is a schematic diagram from one perspective of the decorative panel structure 100 in a retracted state according to one embodiment of this application. Figure 2 for Figure 1 The diagram shows the decorative panel structure 100 from another perspective. Figure 3 for Figure 1 The diagram shown is a schematic representation of the decorative panel structure 100 in its unfolded state from one perspective. Figure 4 for Figure 3 The diagram shows the trim structure 100 from another perspective. The trim structure 100 is located on the inside of the vehicle to provide support. Here, "inside" and "outside" refer to the vehicle itself; the interior space of the vehicle is the inside of the vehicle, and the exterior space of the vehicle is the outside of the vehicle.

[0078] To better illustrate the specific structure of the trim panel structure 100, the structure of the screen device is briefly described here. The vehicle includes a roof panel (not shown), side panels (not shown), and the screen device of this application. The side panels are positioned opposite each other on both sides of the roof panel. The screen device includes a screen structure (not shown) and two trim panel structures 100 of this application. The screen structure is disposed on the inner wall of the roof panel, and the two trim panel structures 100 are positioned opposite each other on the side panels. The screen structure is connected to the trim panel structures 100 and can move along the trim panel structures 100 to achieve the extension and retraction of the screen structure. The screen structure is a projection screen. When the user needs to use the screen structure, they can control the screen structure to extend along the trim panel structures 100 to unfold the screen structure, allowing projection operations to be performed on the screen structure to meet corresponding entertainment needs.

[0079] When the curtain structure is not in use, it can be controlled to move along the trim panel structure 100 to achieve its storage, thereby reducing the space occupied by the curtain structure and increasing the interior space of the vehicle. This also prevents the curtain structure from obstructing the interior space when not in use, improving space utilization. Furthermore, the curtain structure can be stored using a retractable method or a roll-up method; this application does not limit the method. It should be noted that the focus of this application is on the trim panel structure 100; the structure of the curtain structure, its extension and storage principles, and other structures of the curtain device are not the focus of this application and will not be discussed further below.

[0080] Furthermore, the trim panel structure 100 of this application can be unfolded or retracted. When the trim panel structure 100 is unfolded, it extends relative to the vehicle side panel. At this time, the curtain structure can move along the trim panel structure 100 to switch the curtain structure from a retracted state to an unfolded state, and vice versa. After the curtain structure is retracted, the trim panel structure 100 can be retracted relative to the vehicle side panel to reduce the space occupied by the trim panel structure 100 inside the vehicle and improve space utilization. At the same time, it can also ensure the appearance performance of the support component 120 and avoid interference with adjacent support components 120, ensuring the stability of the unfolding and retraction of the trim panel structure 100. The specific structure of the trim panel structure 100 in some embodiments is described below.

[0081] See Figures 1 to 5 In one embodiment, the decorative panel structure 100 includes a fixing portion 110, at least two support components 120, and a transmission component 150. At least two support components 120 are rotatably connected at one end to the fixing portion 110. One support component 120 can move into or out of an adjacent support component 120, allowing at least two support components 120 to be extended or retracted. Each support component 120 includes two support plates 121, which are arranged opposite to each other along a first direction and are connected along the first direction. The transmission component 150 is connected to at least two support components 120 respectively and can drive at least two support components 120 to rotate around the fixing portion 110. Figure 5 for Figure 3 The diagram shows the decorative panel structure 100 after being cut open.

[0082] The fixing part 110 is a component for fixing the trim panel structure 100. The fixing part 110 is fixedly installed on the side panel of the vehicle. Of course, in other embodiments, the fixing part 110 can also be installed on the roof panel. At least two support components 120 are components for supporting the curtain structure. At least two support components 120 are rotatably mounted on the fixing part 110, and thus can be hidden in the side panel of the vehicle by rotating relative to the fixing part 110. Exemplarily, the fixing part 110 is a fixing shaft. Of course, in other embodiments, the fixing part 110 can also be a shaft or pin-like component with a bracket. Specifically, the top ends of at least two support components 120 are rotatably connected to the fixing part 110.

[0083] In this embodiment, at least two support components 120 include a first support component 130 and a second support component 140. That is, the trim panel structure 100 includes two support components 120. Of course, in other embodiments, at least two support components 120 may also include a third support component or even a fourth support component, that is, the trim panel structure 100 may also include three, four or even other numbers of support components 120. One support component 120 is located in an adjacent support component 120, and at least two support components 120 can move relative to each other. One support component 120 can rotate about the fixing part 110 relative to the adjacent support component 120, and the adjacent support component 120 can rotate about the fixing part 110 relative to one of the support components 120.

[0084] When at least two support components 120 rotate and unfold around the fixing part 110, one of the support components 120 can gradually move out of the adjacent support component 120. At this time, at least two support components 120 are unfolded, increasing the area and space occupied by the decorative panel structure 100. When at least two support components 120 rotate and retract, one of the support components 120 can gradually move into the adjacent support component 120. At this time, at least two support components 120 are retracted, reducing the area and space occupied by the decorative panel structure 100.

[0085] In this way, at least two support components 120 can be moved out or into adjacent support components 120 in sequence, so that at least two support components 120 can be unfolded or retracted in sequence, thereby meeting the unfolding or retraction requirements of the decorative panel structure 100. Furthermore, the curtain structure is slidably connected to one of the support components 120. After at least two support components 120 are unfolded, the curtain structure can slide along the corresponding support component 120, so that the curtain structure can extend or retract relative to the corresponding support component 120. And after the curtain structure is retracted, at least two support components 120 can be retracted.

[0086] The transmission component 150 is the part that transmits motion to the decorative panel structure 100, and is connected to at least two support components 120. When the transmission component 150 moves, it can drive at least two support components 120 to rotate around the fixed part 110, thereby controlling the unfolding or retraction of the at least two support components 120. Furthermore, the curtain device also includes a drive structure, which is the power source for the unfolding and retraction of the decorative panel structure 100. The transmission component 150 can be connected to the drive structure of the curtain device. The drive structure can drive the transmission component 150 to move the at least two support components 120. Optionally, the drive structure can be a combination of a handle or a drive motor and gears, etc., to achieve manual or automatic control of the transmission component 150. Of course, the drive structure can also be other structural forms capable of driving the transmission component 150, which will not be elaborated upon in this application. It should be noted that the structure and motion principle of the transmission component 150 are not the focus of this application; the current transmission component 150 can be used to drive the at least two support components 120, and will not be elaborated upon in this application.

[0087] It should be noted that the structure and movement principle of two support components 120 are substantially the same as those of three or other numbers of support components 120. This application only uses at least two support components 120, including the first support component 130 and the second support component 140, as an example for illustration. Other numbers of support components 120 will not be described in detail. Furthermore, the first support component 130 and the second support component 140 have both identical and different structures. When describing the structure of the first support component 130 and the second support component 140 later, the identical parts will be described using the support component 120, and the different parts will be described using the first support component 130 and the second support component 140.

[0088] Each support assembly 120 includes two support plates 121, which are arranged opposite to each other along a first direction of the support assembly 120. To better illustrate the structure of the support assembly 120, the terms "first direction," "second direction," and "third direction" are introduced here, such as... Figures 1 to 4 As shown, the thickness direction of the support component 120 is denoted as the first direction, the height direction and extension direction of the support component 120 are denoted as the second direction, and the width direction of the support component 120 is denoted as the third direction. Each direction of the support component 120 is defined by... Figures 1 to 4 Based on the first, second, and third directions shown, they will not be elaborated upon further.

[0089] Two support plates 121 are arranged opposite each other along a first direction and connected to each other to improve the stability of the connection between the two support plates 121 along the first direction and prevent the two support plates 121 from opening outward along the first direction, thus preventing the two support plates 121 from separating. In this way, the appearance of the support assembly 120 can be guaranteed, and at the same time, the support assembly 120 can be guaranteed to provide stable support to adjacent support assemblies 120, avoiding interference between adjacent support assemblies 120, and improving the stability and reliability of the unfolding and retraction of the decorative panel structure 100.

[0090] The trim panel structure 100 of the above embodiment expands or retracts at least two support components 120 by rotating them around the fixing part 110. When expanded, the curtain structure can extend to meet specific needs; when retracted, it reduces the space occupied by the trim panel structure 100 inside the vehicle, improving interior space utilization without affecting the overall aesthetics. Simultaneously, the two support plates 121 in each support component 120 are arranged opposite to and connected along a first direction. This ensures that the distance between the two support plates 121 along the first direction is approximately equal, preventing them from expanding outwards, maintaining the appearance of the support component 120, avoiding interference with adjacent support components 120, and ensuring the stability of the trim panel structure 100 during expansion and retraction.

[0091] See Figure 7 and Figure 8 In one embodiment, each support assembly 120 further includes a connecting member 123, which is disposed on the inner wall of one end of the two support plates 121 away from the fixing part 110, so as to connect the two support plates 121 away from the fixing part 110. Figure 8 for Figure 7 The diagram shows a partial enlarged view of the first support assembly 130 at point A. The connecting component 123 is a component that enables a stable connection between the two support plates 121 in the same support assembly 120. It is understood that after the two support plates 121 abut against each other at the ends away from the fixing part 110, there may be a certain gap between the two support plates 121, which may affect the stability of the support assembly 120 structure.

[0092] Therefore, this application designates connecting components 123 on the inner bottom walls of the two support plates 121, and arranges them opposite to the fixing part 110 along the second direction. After the two support plates 121 are arranged opposite each other, they are connected and fixed into a whole by the connecting components 123 at the bottom, so that the distance between the two support plates 121 along the first direction is approximately equal. This improves the stability of the connection between the two support plates 121 along the first direction, preventing the two support plates 121 from opening outward along the first direction and thus preventing the two support plates 121 from separating. This ensures the aesthetic appearance of the support assembly 120, while also ensuring the stable support of the support assembly 120 for adjacent support assemblies 120, avoiding interference between adjacent support assemblies 120, and improving the stability and reliability of the unfolding and retraction of the decorative panel structure 100.

[0093] See Figure 7 and Figure 8 In one embodiment, the connecting component 123 includes a first fastener 1231 and a second fastener 1232. The first fastener 1231 and the second fastener 1232 are respectively disposed on two support plates 121 and are arranged opposite to each other. The first fastener 1231 and the second fastener 1232 are snapped together along a first direction. The first fastener 1231 is disposed on the inner bottom wall of one of the support plates 121, and the second fastener 1232 is disposed on the inner bottom wall of the other support plate 121. The first fastener 1231 and the second fastener 1232 are arranged opposite to each other. When the two support plates 121 are assembled along the first direction, the first fastener 1231 and the second fastener 1232 are snapped together along the first direction to achieve reliable fixation of the two support plates 121, so that the ends of the two support plates 121 away from the fixing part 110 abut against each other, thereby further improving the structural stability of the support assembly 120.

[0094] In this embodiment, the first fastener 1231 is a hook, and the second fastener 1232 has a slot. After the two support plates 121 abut against each other, the hook and the slot engage along the first direction, so that the hook is engaged in the slot. In this way, the slot can fix and limit the hook, thereby achieving reliable fixation of the two support plates 121. Of course, in other embodiments, the second fastener 1232 may have a engaging protrusion, or the first fastener 1231 may have a slot and the second fastener 1232 may be a hook, or both the first fastener 1231 and the second fastener 1232 may be hooks.

[0095] See Figure 7 and Figure 13In one embodiment, there are multiple connecting members 123, which are spaced apart along a third direction of the support plate 121. By connecting the two support plates 121 along a third direction with multiple connecting members 123, the ends of the two support plates 121 away from the fixing part 110 abut against each other, thereby further improving the structural stability of the support assembly 120.

[0096] See Figures 1 to 7 In one embodiment, the support plate 121 includes a support body 1201 and a cover plate body 1202. One end of the support body 1201 is rotatably connected to the fixing part 110, and the other end of the support body 1201 is connected to the cover plate body 1202. The end of the cover plate body 1202 away from the support body 1201 can abut against the edge of the cover plate body 1202 of the opposite support plate 121. The support body 1201 is a side plate of the support plate 121, and the cover plate body 1202 is a bottom plate of the support body 1201. The support body 1201 extends along a second direction and has a certain thickness along a first direction. One end of the support body 1201 is rotatably connected to the fixing part 110, and the other end of the support body 1201 is connected to the cover plate body 1202. The cover plate body 1202 extends along the first direction and has a certain thickness along the second direction.

[0097] When the two support plates 121 are connected, the end of the cover plate body 1202 away from the support body 1201 abuts against the end of the opposite cover plate body 1202. In this way, the two support bodies 1201 can form a closed structure at the bottom through the two cover plates 1202, ensuring the aesthetic appearance of the support assembly 120 and improving the user experience. Simultaneously, the two cover plates 1202 can support the two support bodies 1201, ensuring a relatively fixed distance between them. Furthermore, the transmission assembly 150 can be connected to the support body 1201 to drive its movement. In this embodiment, the transmission assembly 150 connects to both support bodies 1201. Of course, in other embodiments, the transmission assembly 150 may connect to only one support body 1201.

[0098] See Figure 7 and Figure 8 In one embodiment, connecting components 123 are respectively disposed on the cover plate bodies 1202 of the support plates 121 opposite each other along the first direction. That is, the first fastener 1231 is disposed on the inner wall of one of the cover plate bodies 1202, and the second fastener 1232 is disposed on the inner wall of the other cover plate body 1202. When the two support plates 121 are assembled along the first direction, the first fastener 1231 and the second fastener 1232 are engaged and connected along the first direction to fix the two cover plate bodies 1202 together, so as to achieve end abutment of the two cover plate bodies 1202 and improve the structural stability of the support assembly 120.

[0099] See Figure 7 and Figure 8 In one embodiment, the cover plate body 1202 is arc-shaped. This gives the side of the support assembly 120 a generally U-shaped profile. The arc-shaped cover plate body 1202 increases the smoothness of the bottom of the support plate 121, minimizing the sharp edges of the bottom of the support assembly 120 and improving its appearance. It also prevents interference with other components. In other embodiments, the cover plate body 1202 may be flat and arranged in an inclined or horizontal position.

[0100] See Figures 1 to 7 In one embodiment, the cover plate body 1202 and the support body 1201 are an integral structure. This reduces the number of parts, simplifies the assembly process, and ensures the structural strength of the connection between the cover plate body 1202 and the support body 1201, preventing breakage at the connection.

[0101] See Figures 1 to 7 In one embodiment, at least two support components 120 include at least a first support component 130 and a second support component 140. One end of both the first support component 130 and the second support component 140 is rotatably connected to the fixing part 110. The first support component 130 has a first space 131, and the second support component 140 can move into or out of the first space 131. The first support component 130 is hollow, and its internal cavity is the first space 131. When the first support component 130 and the second support component 140 rotate and unfold around the fixing part 110, the second support component 140 can gradually move out of the first space 131 of the first support component 130. At this time, the first support component 130 and the second support component 140 unfold, and the area and space occupied by the decorative panel structure 100 increase. When the first support component 130 and the second support component 140 rotate and retract, the second support component 140 can gradually move into the first space 131 of the first support component 130. At this time, the first support component 130 and the second support component 140 retract, reducing the area and space occupied by the decorative panel structure 100.

[0102] See Figure 6 , Figure 7 , Figure 9 and Figure 10 In one embodiment, the first support assembly 130 includes a support member 133, and the support plate 121 in the first support assembly 130 is a first support plate 132. The two first support plates 132 are arranged opposite each other along a first direction, and the support member 133 is disposed in the middle region of the two first support plates 132 along the first direction to connect the two first support plates 132. Figure 9 for Figure 3Perspective view of the first support component 130 and the second support component 140 in the decorative panel structure 100 shown. Figure 10 for Figure 9 The first support component 130 shown is a cross-sectional view along the BB direction.

[0103] The support plate 121 in the first support assembly 130 is designated as the first support plate 132. Two first support plates 132 are arranged opposite each other along a first direction. A support member 133 is a component that supports and connects the two first support plates 132. The support member 133 is actually connected to the support body 1201 of the first support plate 132; that is, the support member 133 is located on the inner sidewall of the first support plate 132, not on its inner bottom wall. With the support member 133 positioned on the inner sidewall of the two first support plates 132, it can support and connect the two first support plates 132 along the first direction. In this way, the support member 133 can keep the distance between the two first support plates 132 approximately constant, preventing them from getting too close to each other and rubbing against the second support assembly 140, and also preventing them from moving too far apart, which could affect the structural strength of the first support assembly 130, while reducing the space occupied and ensuring the structural stability of the first support assembly 130.

[0104] Furthermore, the support member 133 is located on the side of the first support plate 132 away from the second support assembly 140, that is, the support member 133 is located on the side of the first support plate 132 away from the second support assembly 140 when entering and exiting the first space 131. After the support member 133 is located on the side of the first support plate 132 away from the second support assembly 140, there is a preset distance between the support member 133 and the second support assembly 140 to prevent interference between the support member 133 and the second support assembly 140 when the first support assembly 130 and the second support assembly 140 are retracted.

[0105] See Figure 6 , Figure 7 , Figure 9 and Figure 10In one embodiment, the support component 133 includes a connector 1331 and a mating component 1332. The connector 1331 and the mating component 1332 extend along a first direction and are disposed opposite to each other on two first support plates 132. The connector 1331 and the mating component 1332 are mated together to support and connect the two first support plates 132. The connector 1331 is disposed on the inner sidewall of one of the first support plates 132, and the mating component 1332 is disposed on the inner sidewall of the other first support plate 132. The connector 1331 and the mating component 1332 are disposed opposite to each other along the first direction. When the two first support plates 132 are assembled along the first direction, the connector 1331 and the mating component 1332 are mated together to achieve the supporting connection of the two first support plates 132, thereby ensuring the stability of the structure of the first support assembly 130.

[0106] See Figure 6 , Figure 7 , Figure 9 and Figure 10 In the first embodiment of this application, the connector 1331 is a first snap-fit ​​member, and the mating member 1332 is a second snap-fit ​​member. After the two first support plates 132 are arranged opposite each other, the first snap-fit ​​member and the second snap-fit ​​member snap-fit ​​together to achieve the supporting connection of the two first support plates 132, thereby ensuring the stability of the structure of the first support assembly 130. In this embodiment, the first snap-fit ​​member is a hook, and the second snap-fit ​​member is provided with a slot. After the two first support plates 132 are arranged opposite each other, the hook is engaged in the slot. In this way, the slot can fix and limit the hook to support and limit the two first support plates 132. Of course, the second snap-fit ​​member may also be provided with a snap-fit ​​protrusion, or the first snap-fit ​​member may be provided with a slot, the second snap-fit ​​member may be provided with a hook, or both the first and second snap-fit ​​members may be hooks, and the two hooks may be engaged together to achieve the supporting and limiting of the two first support plates 132.

[0107] In the second embodiment of this application, the connector 1331 is a first insertion member, and the mating member 1332 is a second insertion member. One of the first and second insertion members is a post, and the other is a slot, with an interference fit between the post and the slot. After the two first support plates 132 are arranged opposite each other, the post is interference-fitted into the slot, and the post and slot are fixed and limited through the interference fit, thereby achieving the support and limitation of the two first support plates 132. Of course, in other embodiments, the connector 1331 and the mating member 1332 can also be other structural forms capable of achieving the inner wall support connection of the two first support plates 132.

[0108] See Figure 6In one embodiment, the first support assembly 130 includes a plurality of support members 133, which are disposed along a second direction on two first support plates 132 and have a predetermined distance from the second support assembly 140. This allows the plurality of support members 133 to provide support at various points along the second direction, ensuring that the distance between the two first support plates 132 remains substantially constant, thereby improving the stability of the first support assembly 130 structure. Furthermore, the predetermined distance between the plurality of support members 133 and the second support assembly 140 prevents interference between the support members 133 and the second support assembly 140 when they are retracted.

[0109] See Figures 1 to 6 , Figure 9 In one embodiment, the second support assembly 140 includes a guide rail 141, and the support plate 121 in the second support assembly 140 is a second support plate 142. The two second support plates 142 are disposed opposite to each other on both sides of the guide rail 141 along a first direction. One end of the guide rail 141 is rotatably mounted to the fixing part 110. The guide rail 141 is used for moving the curtain structure of the curtain device. The support plate 121 in the second support assembly 140 is referred to as the second support plate 142, and the two second support plates 142 are disposed opposite to each other along the first direction.

[0110] The guide rail 141 extends generally along the extension direction of the second support plate 142, that is, the guide rail 141 extends along the second direction. The guide rail 141 serves as the track for the movement of the curtain structure. The top of the second support plate 142 is rotatably connected to the fixing part 110. The two second support plates 142 are arranged opposite each other in the second direction and are located opposite each other on the outer side of the guide rail 141. The second support plate 142 is connected to the guide rail 141, and the transmission assembly 150 is also connected to the guide rail 141. The transmission assembly 150 can drive the guide rail 141 to move, and in turn, the guide rail 141 can drive the second support plate 142 to rotate around the fixing part 110, so that the second support assembly 140 moves into or out of the first space 131.

[0111] In the initial state, the second support plate 142 and the guide rail 141 are located in the first space 131, so that the first support plate 132 and the second support plate 142 are in a retracted state, thereby reducing the space occupied by the first support assembly 130 and the second support assembly 140 inside the vehicle and improving space utilization. During deployment, the transmission assembly 150 drives the first support plate 132 and the guide rail 141 to move, and the guide rail 141 drives the second support plate 142 to move relative to the first support plate 132, causing the guide rail 141 to move the second support plate 142 out of the first space 131, thus unfolding the first support assembly 130 and the second support assembly 140. During retraction, the first support plate 132 and the second support plate 142 can rotate around the fixing part 110, causing the guide rail 141 to move the second support plate 142 into the first space 131, thus retracting the first support assembly 130 and the second support assembly 140.

[0112] See Figure 11 and Figure 12 In one embodiment, the guide rail 141 has a second space 143 and a slide groove 1411. The second space 143 and the slide groove 1411 are respectively disposed on both sides of the guide rail 141 along a third direction. The transmission component 150 is at least partially located in the second space 143. The second space 143 is connected to the first space 131. The slide groove 1411 is used for the curtain structure to slide. Figure 11 for Figure 3 A perspective view of the second support component 140 in the decorative panel structure 100 shown. Figure 12 for Figure 11 The second support assembly 140 shown is a cross-sectional view along the CC direction. Figure 12 In this configuration, the second space 143 and the slide rail 1411 are located on opposite sides of the guide rail 141, and the second space 143 and the slide rail 1411 are not connected. This allows the curtain structure to unfold or retract along the slide rail 1411, and the transmission component 150 is housed within the second space 143, preventing interference between the curtain structure and the transmission component 150. Furthermore, by housing at least a portion of the transmission component 150 within the second space 143, the space occupied by the transmission component 150 on the outside of the decorative panel structure 100 is reduced, minimizing interference between the transmission component 150 and external components.

[0113] See Figures 11 to 13 In one embodiment, the second support assembly 140 further includes an elastic clip 144. The surface of the guide rail 141 facing the second support plate 142 is provided with a mounting hole 1412. The surface of the second support plate 142 facing the guide rail 141 is provided with a mounting member 1421. The mounting member 1421 is installed in the mounting hole 1412. The elastic clip 144 engages with the mounting member 1421 and is secured in the mounting hole 1412. Figure 13 for Figure 12A schematic diagram showing the engagement of the elastic clip 144 and the second support plate 142 in the second support assembly 140.

[0114] The guide rail 141 and the second support plate 142 are connected by an elastic clip 144. On one hand, the elastic clip 144 can absorb assembly errors between the guide rail 141 and the second support plate 142, facilitating their assembly. On the other hand, the elastic clip 144 can limit the movement of the second support plate 142, preventing it from moving away from the guide rail 141 and improving the reliability of the connection between them. It should be noted that the connection methods between the two second support plates 142 and the guide rail 141 are essentially the same; this description only uses the connection of one second support plate 142 to the guide rail 141 as an example.

[0115] The inner surface of the second support plate 142 is provided with a protruding mounting member 1421. The guide rail 141 is provided with a mounting hole 1412 communicating with the second space 143. The elastic clip 144 can be clipped onto the outer wall of the guide rail 141 and extends into the second space 143 through the mounting hole 1412. Furthermore, the elastic clip 144 can also clip onto the mounting member 1421. In this way, after the elastic clip 144 clips onto the mounting member 1421, a fixed connection between the elastic clip 144 and the second support plate 142 can be achieved. When the elastic clip 144 is clipped into the mounting hole 1412 of the guide rail 141, a fixed connection between the elastic clip 144 and the guide rail 141 can also be achieved, so as to reliably fix the second support plate 142 to the guide rail 141. Meanwhile, after the elastic clip 144 fixes the second support plate 142 and the guide rail 141, it can also fix the distance between the second support plate 142 and the guide rail 141, which is convenient for fixing the decorative part 145 (mentioned later) and avoids the expansion of the decorative part.

[0116] See Figures 11 to 13 In one embodiment, the elastic clip 144 includes a mounting body 1441 and a limiting body 1442 and an abutting body 1443 disposed on the mounting body 1441. The mounting body 1441 protrudes from the outer wall of the limiting body 1442 and abuts against the surface of the guide rail 141 facing the second support plate 142. The limiting body 1442 extends into the inner side of the second support plate 142 through a mounting hole 1412 and at least partially abuts against the inner wall of the guide rail 141. The limiting body 1442 can cover the mounting member 1421. The abutting body 1443 is located in the limiting body 1442 and abuts against the mounting member 1421.

[0117] The limiting body 1442 is disposed on one surface of the mounting body 1441 and protrudes toward the second space 143. The abutting body 1443 is disposed on one surface of the mounting body 1441 and extends toward the interior of the limiting body 1442. When the elastic clip 144 is connected to the second support plate 142, the mounting body 1441 can abut against the inner surface of the second support plate 142. At the same time, the limiting body 1442 can be sleeved on the outer side of the protruding mounting member 1421, and the abutting body 1443 can abut against the mounting member 1421 in the limiting body 1442, thereby realizing the installation and fixation of the elastic clip 144 and the second support plate 142.

[0118] When the elastic clip 144 is connected to the guide rail 141, the limiting body 1442 can extend into the second space 143 through the mounting hole 1412. Because the elastic clip 144 has elastic properties, during the process of the limiting body 1442 passing through the mounting hole 1412, the inner wall of the mounting hole 1412 can compress the limiting body 1442, allowing the portion of the limiting body 1442 away from the mounting body 1441 to gradually extend into the second space 143. When the surface of the mounting body 1441 away from the second support plate 142 abuts against the guide rail 141, it indicates that the elastic clip 144 is installed in place. At this time, part of the limiting body 1442 is located in the mounting hole 1412, and part is located in the second space 143. Furthermore, the portion of the limiting body 1442 in the second space 143 can be reset under the action of elastic force and abut against the inner wall of the guide rail 141. At this time, the mounting body 1441 abuts against the outer wall of the guide rail 141, and the limiting body 1442 abuts against the inner wall of the guide rail 141, so that the elastic clip 144 is locked in the guide rail 141, realizing the fixed connection between the elastic clip 144 and the guide rail 141. The connection between the elastic clip 144 and the second support plate 142 can reliably fix the second support plate 142 to the guide rail 141.

[0119] See Figures 11 to 13 In one embodiment, the mounting member 1421 is provided with an abutting portion for abutting the abutting body 1443. The abutting portion is either an abutting protrusion or an abutting groove. After the limiting body 1442 is sleeved on the mounting member 1421, the abutting body 1443 can abut against the abutting portion, realizing a reliable connection between the abutting body 1443 and the mounting member 1421, thereby realizing a reliable connection between the elastic clip 144 and the second support plate 142. Furthermore, the form of the abutting portion is not limited in principle, as long as the abutting body 1443 can abut against the abutting portion. In this embodiment, the abutting portion is an abutting protrusion such as a hook, and the end of the abutting body 1443 can abut against the abutting protrusion. Of course, in other embodiments, the abutting portion can also be an abutting groove, and the end of the abutting body 1443 can be engaged in the abutting groove.

[0120] See Figures 11 to 13In one embodiment, at least one side of the limiting body 1442 is provided with an arched portion 14421 facing outward of the mounting member 1421, and the arched portion 14421 protrudes from the inner wall of the mounting hole 1412. That is, the side of the limiting body 1442 protrudes to form the arched portion 14421. In this way, after the limiting body 1442 extends into the second space 143, the arched portion 14421 is located in the second space 143, and the arched portion 14421 can abut against the inner wall of the mounting hole 1412 to abut against the inner wall of the guide rail 141, so that the elastic clip 144 can be engaged with the inner wall of the guide rail 141.

[0121] See Figures 11 to 13 In one embodiment, the mounting body 1441, the limiting body 1442, and the abutting body 1443 are integrated into one structure. This reduces the number of parts, simplifies the production and assembly process, and at the same time ensures the structural strength of the mounting body 1441, the limiting body 1442, and the abutting body 1443 at the connection point, preventing breakage and thus ensuring the performance of the elastic clip 144.

[0122] See Figures 11 to 13 In one embodiment, the mounting body 1441, the limiting body 1442, and the abutting body 1443 are sheet-like structures. This allows for a reduction in the weight and cost of the elastic clip 144 without affecting its ability to secure the second support plate 142 and the guide rail 141. Optionally, the side of the elastic clip 144 is generally arranged in a Z-shape.

[0123] See Figures 11 to 13 In one embodiment, there are multiple elastic clips 144, which are spaced apart along the second direction of the second support plate 142. This allows the multiple elastic clips 144 to connect the second support plate 142 and the guide rail 141 in the second direction, improving the reliability of the connection between the second support plate 142 and the guide rail 141, thereby increasing the structural strength of the second support assembly 140.

[0124] See Figures 11 to 13 In one embodiment, the guide rail 141 is provided with a sliding groove 1411 for the curtain structure to slide. The elastic clip 144 is offset from the sliding groove 1411 along a third direction. That is, the mounting hole 1412 on the guide rail 141 is offset from the sliding groove 1411 along a third direction. This avoids interference between the elastic clip 144 and the curtain structure, and at the same time, ensures the structural strength of the guide rail 141, thereby improving the overall structural strength of the second support assembly 140.

[0125] See Figure 11 , Figure 12 and Figure 14In one embodiment, the second support assembly 140 further includes a decorative element 145, which is partially disposed between the guide rail 141 and the second support plate 142, partially covering the outside of the guide rail 141, and is connected to the second support plate 142. Figure 14 for Figure 11 The diagram shows a cross-sectional view of the second support assembly 140 along the DD direction. One end of the decorative piece 145 is inserted between the guide rail 141 and the second support plate 142, and the other end of the decorative piece 145 extends out from the side of the guide rail 141. In this way, the decorative piece 145 serves a decorative function while also obscuring the guide rail 141, thus improving the appearance of the second support assembly 140. It should be noted that the shape of the decorative piece 145 is not limited in principle, as long as it can obscure the guide rail 141 and does not affect the movement of the curtain structure. Optionally, there are two decorative pieces 145, one between each second support plate 142 and guide rail 141.

[0126] Optionally, the end of the trim 145 away from the second support plate 142 protrudes inward toward the guide rail 141. That is, one end of the trim 145 is inserted between the second support plate 142 and the guide rail 141, the trim 145 is also partially located on the outside of the guide rail 141, and the other end of the trim 145 protrudes from the end of the guide rail 141 and extends inward toward the guide rail 141 to extend toward the groove 1411. In this way, the trim 145 can protect the guide rail 141.

[0127] See Figure 11 , Figure 12 and Figure 14 In one embodiment, the second support plate 142 has a recess 1422 on the side facing the guide rail 141, which together with the guide rail 141 forms a mounting cavity 1423. The decorative piece 145 is partially installed in the mounting cavity 1423. That is, the inner surface of the second support plate 142 is recessed to form the recess 1422, which together with the outer surface of the guide rail 141 forms the mounting cavity 1423. One end of the decorative piece 145 is inserted into the mounting cavity 1423 and connected to the second support plate 142. The mounting cavity 1423 facilitates the installation of the decorative piece 145, avoids interference fit between the decorative piece 145 and the second support plate 142 which could cause deformation of the second support plate 142, and improves the structural stability of the second support assembly 140.

[0128] See Figure 11 , Figure 12 , Figures 14 to 18In one embodiment, the decorative element 145 includes a connecting body 1451 and a covering body 1452 disposed on the connecting body 1451. The connecting body 1451 is installed between the second support plate 142 and the guide rail 141 and is connected to the second support plate 142. The covering body 1452 is located on the outside of the second support plate 142 and covers the outside of the guide rail 141. Figure 15 for Figure 9 The first support assembly 130 and the second support assembly 140 shown are cross-sectional views along the EE direction. Figure 16 for Figure 15 A partial enlarged view of the second support component 140 at point F, as shown. Figure 17 for Figure 9 A schematic diagram of the second support component 140 is shown. Figure 18 for Figure 17 The second support component 140 shown is a cross-sectional view along the GG direction.

[0129] The connecting body 1451 is installed into the mounting cavity 1423 and can connect with the second support plate 142 to fix the decorative piece 145 to the second support plate 142. The covering body 1452 is located outside the mounting cavity 1423 and outside the second support plate 142 and the guide rail 141. In this way, the covering body 1452 can cover the guide rail 141 and decorate the side of the second support assembly 140 away from the first support assembly 130, improving the aesthetics of the decorative panel structure 100. At the same time, it can also protect the curtain structure in the guide rail 141.

[0130] Optionally, the covering body 1452 is bent relative to the connecting body 1451. This allows the covering body 1452 to abut against the end face of the second support plate 142 and cover the guide rail 141. Simultaneously, the end of the covering body 1452 away from 1451 protrudes inward towards the guide rail 141 to protect it. Optionally, the covering body 1452 and the connecting body 1451 are an integral structure. This facilitates the molding and processing of the decorative part 145, simplifies production and assembly processes, and improves the structural strength at the connection between the covering body 1452 and the connecting body 1451.

[0131] See Figure 11 , Figure 12 and Figure 14 In one embodiment, the decorative element 145 is bonded to the second support plate 142. That is, the decorative element 145 and the second support plate 142 are connected by adhesive. At this time, a certain gap can be provided between the decorative element 145 and the second support plate 142 to facilitate the injection of glue or the like to bond the decorative element 145 and the second support plate 142.

[0132] See Figure 11 , Figure 12 , Figures 14 to 18 In one embodiment, the decorative element 145 is welded to the second support plate 142. Welding the decorative element 145 to the second support plate 142 improves the reliability of the connection and prevents the decorative element 145 from detaching from the second support plate 142. Optionally, the decorative element 145 can be fixed to the second support plate 142 by laser welding. Alternatively, the decorative element 145 can also be fixed to the second support plate 142 by piercing welding. Of course, in other embodiments, the decorative element 145 can also be fixed to the second support plate 142 by other welding methods or other fixing methods.

[0133] See Figure 11 , Figure 12 , Figures 14 to 16 In one embodiment, the decorative element 145 protrudes from the surface of the second support plate 142 onto the welding boss 1453. The surface of the welding boss 1453 is provided with a recessed first groove 1454, which is used to divide the welding boss 1453 into at least two welding surfaces 1455 in a third direction. The welding surfaces 1455 are welded to the second support plate 142. The first groove 1454 can divide the surface of the welding boss 1453 in a third direction to divide the surface of the welding boss 1453 into at least two welding surfaces 1455.

[0134] When the decorative element 145 is connected to the second support plate 142 by laser welding, each welding surface 1455 can correspond to a laser welding head to weld the welding surface 1455 to the second support plate 142. The first groove 1454 facilitates the welding fusion of the welding surface 1455 and the surface of the second support plate 142, improving the reliability of the welding between the decorative element 145 and the second support plate 142. In this embodiment, the welding boss 1453 has a first groove 1454 along a third direction, dividing the surface of the welding boss 1453 into two welding surfaces 1455. Of course, in other embodiments, the welding boss 1453 may also have at least two first grooves 1454 along a third direction, dividing the surface of the welding boss 1453 into at least three welding surfaces 1455.

[0135] See Figure 11 , Figure 12 , Figures 14 to 16 In one embodiment, there are multiple first grooves 1454, which are spaced apart along the second direction. The multiple first grooves 1454 arranged along the second direction can divide the surface of the welding boss 1453 at corresponding positions into at least two welding surfaces 1455 in the second direction. This increases the number of welding positions between the trim 145 and the second support plate 142 along the second direction, improving the reliability of the welding between the trim 145 and the second support plate 142.

[0136] See Figure 11 , Figure 12 , Figures 14 to 18 In one embodiment, the surface of the ornament 145 facing away from the second support plate 142 is provided with a recessed second groove 1456. The second groove 1456 is used to accommodate the welding point when the second support plate 142 and the ornament 145 are welded together. The second groove 1456 is recessed on the surface of the ornament 145 facing the guide rail 141. When the ornament 145 and the second support plate 142 are connected by piercing welding, a protruding welding point will be generated on the back side of the welding area, that is, the surface of the ornament 145 facing away from the second support plate 142. To this end, the present application provides a second groove 1456 on the surface of the ornament 145 facing away from the second support plate 142. By accommodating the protruding welding point, the second groove 1456 avoids the welding point from contacting the outer surface of the guide rail 141, thereby avoiding interference between the ornament 145 and the guide rail 141.

[0137] See Figure 11 , Figure 12 , Figures 14 to 18 In one embodiment, there are multiple second grooves 1456, which are spaced apart along a second direction. The multiple second grooves 1456 arranged along the second direction can accommodate welding points at corresponding positions in the second direction. This increases the number of welding positions between the trim 145 and the second support plate 142 along the second direction, improving the reliability of the welding between the trim 145 and the second support plate 142.

[0138] See Figure 1 and Figure 19 In one embodiment, the support plate 121 includes a main plate 1211 and a skeleton layer 1212, the skeleton layer 1212 being disposed on the inner surface of the main plate 1211. Figure 19 for Figure 1 The diagram shows a cross-sectional view of the decorative panel structure 100 along the HH direction. The skeleton layer 1212 forms the main frame supporting the panel 121, and the main panel 1211 is the main layer supporting the panel 121. The skeleton layer 1212 is located inside the main panel 1211, providing support to the main panel 1211 and thus improving the structural strength of the supporting panel 121. It should be noted that the two supporting panels 121 have identical structures; the following description will only use the structure of one of the supporting panels 121 as an example.

[0139] See Figure 19 In the first embodiment of this application, the main body plate 1211 and the skeleton layer 1212 are integrally injection molded. That is, the skeleton layer 1212 and the main body plate 1211 are integrally molded by injection molding to reduce the number of parts, simplify the production and assembly process of the support plate 121, and at the same time ensure that the support plate 121 has a high degree of fit and stability when it moves.

[0140] See Figure 9 and Figure 20 In the second embodiment of this application, the main body plate 1211 and the skeleton layer 1212 are separate structures, and there is a preset gap 102 between the main body plate 1211 and the skeleton layer 1212. Figure 20 for Figure 9 The diagram shows a cross-sectional view of the first support assembly 130 and the second support assembly 140 along direction II. In this embodiment, the main body plate 1211 and the skeleton layer 1212 are respectively processed and formed, and then the main body plate 1211 and the skeleton layer 1212 are assembled. The main body plate 1211 and the skeleton layer 1212 are respectively formed by injection molding, and then the main body plate 1211 and the skeleton layer 1212 are assembled together, with a preset gap 102 between them. It is understood that the main body plate 1211 and the skeleton layer 1212 have a large difference in specific heat capacity. In actual use, the main body plate 1211 and the skeleton layer 1212 will undergo large deformation and bending deformation. At this time, the preset gap 102 can absorb the bending deformation and tolerance of the main body plate 1211 and the skeleton layer 1212, ensuring the strength and appearance flatness of the assembled main body plate 1211 and the skeleton layer 1212.

[0141] See Figure 9 and Figure 20 In one embodiment, the main body plate 1211 and the skeleton layer 1212 are bonded, fused, or welded together. The main body plate 1211 and the skeleton layer 1212 can be assembled together by means of hot melting, welding, or bonding to ensure the reliability of the connection between them. Optionally, the bonding method includes, but is not limited to, using double-sided tape, foam adhesive, strong adhesive tape, adhesive, polyurethane resin adhesive (PU adhesive), etc. Optionally, the main body plate 1211 and the skeleton layer 1212 are connected by laser welding.

[0142] See Figure 20 and Figure 21 In one embodiment, the main body plate 1211 is provided with a protrusion 12111, and the skeleton layer 1212 is provided with a mating hole 12121. The protrusion 12111 extends through the mating hole 12121 and can be locked onto the inner surface of the skeleton layer 1212. Figure 21 for Figure 20The diagram shows a partial enlarged view of the first support assembly 130 and the second support assembly 140 at point J. A protrusion 12111 is provided on the inner surface of the main body plate 1211. The protrusion 12111 has a boss-like structure. A mating hole 12121 is provided on the skeleton layer 1212 corresponding to the position of the protrusion 12111. After the skeleton layer 1212 covers the periphery of the inner surface of the main body plate 1211, the protrusion 12111 is installed in the mating hole 12121. Furthermore, after heat fusion or other treatments such as press fitting, the protrusion 12111 can be secured to the inner surface of the skeleton layer 1212. At this time, the protrusion 12111 is approximately T-shaped, and both sides of the protrusion 12111 can abut against the inner surface of the skeleton layer 1212 to secure the main body plate 1211 to the skeleton layer 1212, further achieving the fixation between the main body plate 1211 and the skeleton layer 1212.

[0143] See Figure 20 and Figure 21 In one embodiment, the surface of the skeleton layer 1212 facing away from the main body plate 1211 is provided with a recess 12122, and the protrusion 12111 is at least partially located in the recess 12122. In this way, by accommodating at least part of the protrusion 12111 in the recess 12122, the size of the support plate 121 along the first direction can be reduced, and the size of the protrusion 12111 protruding from the main body plate 1211 can also be reduced, thus avoiding scratches.

[0144] See Figure 14 and Figure 15 In one embodiment, the guide rail 141 is provided with a receiving area 1413, which at least partially receives the protrusion 12111. The receiving area 1413 is a receiving hole or a receiving groove. When the support plate 121 is the second support plate 142, the guide rail 141 is provided with the receiving area 1413 at the position corresponding to the protrusion 12111. After the second support plate 142 is installed on the guide rail 141, the protrusion 12111 is at least partially received in the receiving area 1413. By providing the receiving area 1413 on the guide rail 141, the size of the second support assembly 140 along the first direction can be reduced. In this embodiment, the receiving area 1413 is a receiving hole that penetrates the guide rail 141 along the first direction. Of course, in other embodiments, the receiving area 1413 may also be a receiving groove recessed into the outer wall of the guide rail 141.

[0145] In the third embodiment of this application, the support plate 121 further includes an outer layer 1213, which covers the outer surface of the main plate 1211. The outer layer 1213 at least partially covers the outer side of the main body 1452 layer, and serves to change the color, feel, and appearance, thereby improving the user experience. Of course, in other embodiments, the support plate 121 may only include the main plate 1211, or it may include the main plate 1211 and the outer layer 1213, which will not be elaborated further in this application.

[0146] See Figure 9 , Figure 15 , Figure 22 and Figure 23 In one embodiment, the decorative panel structure 100 further includes a plurality of follower components 160. At least one follower component 160 is provided between any two adjacent support components 120. The follower component 160 is disposed on one of the support components 120 and is opposite to the other support component 120. The follower component 160 is slidably connected to the other support component 120, so that the two adjacent support components 120 maintain a set gap 101. Figure 22 for Figure 9 The first support assembly 130 and the second support assembly 140 shown are cross-sectional views along the KK direction. Figure 23 for Figure 22 A perspective view of the follower component 160 shown.

[0147] A follower component 160 is disposed in the support plate 121 of one of the support components 120 and is opposite to the support plate 121 of the adjacent support component 120. Furthermore, the follower component 160 is slidably connected to the opposite support plate 121. When the transmission component 150 drives the support plate 121 and the guide rail 141 to move, the follower component 160 can move synchronously with the support plate 121 and support the adjacent support plate 121 to prevent the support plates 121 in the two adjacent support components 120 from approaching each other along the first direction, and also to prevent the support plates 121 in the two adjacent support components 120 from moving away from each other along the first direction. Thus, a predetermined gap 101 exists between the support plates 121 in the two adjacent support components 120 along the first direction, so that the predetermined gap 101 between the two adjacent support components 120 is approximately constant. That is, the two adjacent support components 120 can move along a predetermined trajectory, avoiding rubbing and ensuring the smoothness of the unfolding and retraction of at least two support components 120.

[0148] See Figure 15 , Figure 22 and Figure 23In one embodiment, the follower component 160 is an adsorption component. The adsorption component slidably adsorbs opposing support plates 121, preventing the support plates 121 of adjacent support components 120 from approaching each other along a first direction. Simultaneously, the skeleton layer 1212 is made of metal, and the adsorption component can adsorb the first support plate 132, preventing the support plates 121 of adjacent support components 120 from moving away from each other along the first direction. Thus, the set gap 101 between adjacent support components 120 is substantially constant, meaning that adjacent support components 120 can move along a predetermined trajectory, avoiding friction and ensuring the smooth unfolding and retraction of at least two support components 120. Of course, in other embodiments, the follower component 160 can also be a sliding guide, etc.

[0149] Furthermore, since the first support plate 132 is supported by the support member 133, and the second support plate 142 abuts against the first support plate 132 via the follower component 160, the first support plate 132 supports the second support plate 142, thereby improving the structural stability of the second support component 140. In this embodiment, one follower component 160 is provided in each second support plate 142. Of course, in other embodiments, at least two follower components 160 may also be provided in each second support plate 142, and the at least two follower components 160 are arranged at intervals along the second direction and / or the third direction of the second support plate 142.

[0150] See Figure 15 , Figure 22 and Figure 23 In one embodiment, at least one follower component 160 is provided on each second support plate 142. The follower component 160 can slide along the first support plate 132 and can be slidably connected to the first support plate 132, so that a set gap 101 is maintained between the first support plate 132 and the second support plate 142. When the transmission component 150 drives the first support plate 132 and the guide rail 141 to move, the guide rail 141 can drive the second support plate 142 to slide, and then the second support plate 142 can drive the follower component 160 to slide relative to the first support plate 132. Since the follower component 160 is partially located between the first support plate 132 and the second support plate 142, the follower component 160 can abut against the first support plate 132 and the second support plate 142 to prevent the first support plate 132 and the second support plate 142 from getting close to each other. At the same time, the skeleton layer 1212 is made of metal material, and the follower component 160 can attract the first support plate 132, so that the first support plate 132 and the second support plate 142 remain close to each other.

[0151] In other words, the follower component 160 abuts against the first support plate 132 and the second support plate 142, and the follower component 160 also adheres to the first support plate 132. This ensures that a generally constant set gap 101 is formed between the first support plate 132 and the second support plate 142, preventing the set gap 101 from increasing or decreasing. This ensures that the distance between the guide rail 141 and the second support plate 142 remains constant, preventing the decorative piece 145 from expanding outward. At the same time, the distance between each second support plate 142 and the corresponding first support plate 132 is maintained at approximately the set gap 101, so that the second support plate 142 is roughly located in the middle region of the first space 131. This prevents the second support plate 142 from scraping against the first support plate 132, ensuring the smooth movement of the first support component 130 and the second support component 140.

[0152] Furthermore, since the first support plate 132 is supported by the support member 133, and the second support plate 142 abuts against the first support plate 132 via the follower component 160, the first support plate 132 supports the second support plate 142, thereby improving the structural stability of the second support component 140. Of course, in other embodiments, the follower component 160 may also be disposed on the first support plate 132 and slidably connected to the second support plate 142.

[0153] See Figure 11 In one embodiment, the decorative panel structure 100 includes at least two follower components 160, which are spaced apart in a second direction from one of the support components 120. The at least two follower components 160 can support the support plates 121 of two adjacent support components 120 along the second direction, preventing the support plates 121 of two adjacent support components 120 from moving closer together or further apart along the first direction, thus ensuring the smooth movement of the support components 120.

[0154] See Figure 11 In one embodiment, the support plate 121 of one support assembly 120 is provided with a protrusion 1424, which protrudes toward the adjacent support assembly 120, and the follower assembly 160 is disposed on the protrusion 1424. The protrusion 1424 facilitates the support and installation of the follower assembly 160. In this embodiment, the protrusion 1424 is disposed on the second support plate 142 and protrudes toward the first support plate 132 to facilitate the installation of the follower assembly 160. Optionally, the number of protrusions 1424 is equal to the number of follower assemblies 160.

[0155] See Figure 15 , Figure 22 and Figure 23In one embodiment, the follower component 160 includes a mounting housing 161 and a magnetic member 162 disposed on the mounting housing 161. The mounting housing 161 is disposed on the support plate 121 of one of the support components 120 and can slidably abut against and attract the support plate 121 of the other support component 120. For ease of explanation of the structure of the follower component 160, this example only shows the follower component 160 mounted on the second support component 140. The mounting housing 161 is disposed on the second support plate 142 and can slidably abut against the first support plate 132. The magnetic member 162 can attract the skeleton layer 1212. The mounting housing 161 is located on the outer side of the follower assembly 160. A magnetic attractor 162 is disposed within the mounting housing 161, which is positioned on the second support plate 142. The mounting housing 161 protrudes from the outer surface of the second support plate 142 and slidably abuts against the inner surface of the first support plate 132, preventing the first support plate 132 and the second support plate 142 from approaching each other. Furthermore, the magnetic attractor 162 can attract the skeleton layer 1212, bringing the first support plate 132 closer to the second support plate 142. This ensures that the set gap 101 between the first support plate 132 and the second support plate 142 remains substantially constant, improving the stability of the second support assembly 140. Optionally, the magnetic attractor 162 can be a magnet or the like.

[0156] See Figure 15 , Figure 22 and Figure 23 In one embodiment, the follower component 160 further includes a hook 163, which is disposed on the mounting housing 161 and engaged with the second support plate 142. The hook 163 is located at the bottom of the mounting housing 161 and protrudes from the mounting housing 161. After the mounting housing 161 is mounted to the second support plate 142, the hook 163 protrudes from the inner surface of the second support plate 142 and can abut against the inner surface of the second support plate 142, thereby fixing the follower component 160 to the second support plate 142. Optionally, the hook 163 and the mounting housing 161 are an integral structure.

[0157] See Figure 15 , Figure 22 and Figure 23In one embodiment, the mounting housing 161 includes a fixed housing 1611 and a sliding housing 1612 disposed on the fixed housing 1611. The fixed housing 1611 is mounted on the second support plate 142, and the sliding housing 1612 is located between the first support plate 132 and the second support plate 142, and slidably abuts against the first support plate 132. The fixed housing 1611 is a housing fixed in the second support plate 142, and the sliding housing 1612 is a housing slidably abutting against the first support plate 132. The sliding housing 1612 is disposed on the fixed housing 1611 and protrudes from the outer surface of the second support plate 142 so as to slidably abut against the inner surface of the first support plate 132. The sliding housing 1612 separates the first support plate 132 and the second support plate 142, preventing the first support plate 132 and the second support plate 142 from getting close to each other. Optionally, the fixed housing 1611 and the sliding housing 1612 are an integral structure.

[0158] The trim panel structure 100 of this application allows at least two support components 120 to be deployed or retracted by rotating around the fixing part 110. When deployed, the curtain structure can extend to meet specific needs; when retracted, it reduces the space occupied by the trim panel structure 100 within the vehicle, improving interior space utilization without affecting the overall aesthetics. Simultaneously, the two support plates 121 in each support component 120 are arranged opposite to and connected along a first direction. This ensures that the distance between the two support plates 121 along the first direction is approximately equal, preventing outward expansion of the two support plates 121, maintaining the appearance of the support component 120, avoiding interference with adjacent support components 120, and ensuring the stability of the trim panel structure 100 during deployment and retraction.

[0159] This application also provides a curtain device, including a curtain structure, a drive structure, and two decorative panel structures 100 as described in any of the above embodiments. The two decorative panel structures 100 are arranged opposite to each other, with the two ends of the curtain structure respectively connected to the two decorative panel structures 100. When at least two support components 120 in the decorative panel structure 100 are unfolded, the curtain structure extends or retracts along one of the support components 120. The drive structure is connected to the decorative panel structure 100 and is used to control the unfolding or retraction of the at least two support components 120. The curtain device of this application, using the decorative panel structure 100 of the above embodiments, facilitates the extension or retraction of the curtain structure to meet usage requirements. Furthermore, after the curtain structure is retracted, the decorative panel structure 100 can be retracted to reduce the space occupied by the decorative panel structure 100 in the vehicle, improving the utilization rate of the vehicle interior without affecting the overall aesthetics of the interior. Simultaneously, it ensures the stability of the unfolding and retraction of the decorative panel structure 100, thereby guaranteeing the performance of the curtain structure in both extension and retraction.

[0160] This application also provides a vehicle, including a roof panel, side panels, and a curtain device as described in the above embodiments. The curtain structure of the curtain device is installed on the roof panel, and the trim panel structure 100 of the curtain device is installed on the side panels. When the vehicle of this application adopts the curtain device of the above embodiments, it can enhance the vehicle's entertainment and functional experience. Simultaneously, when the curtain device is not in use, the space occupied by the trim panel structure 100 within the vehicle interior is reduced, improving the utilization rate of the vehicle interior without affecting the overall aesthetics of the interior.

[0161] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0162] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
