[0050] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0052] In some scenarios, the placement of display devices can reduce the overall space utilization of the environment, and the devices themselves are also more susceptible to damage. For example, in the automotive field, display devices are often installed behind the seats, typically protruding from the seat structure. This makes the display devices vulnerable to impacts and collisions, potentially leading to display errors. 42

[0053] To address the aforementioned issues, please refer to Figures 1 to 3. This application provides a display device including a supporting component 1, a display screen 2, a blocking component 3, and a transmission assembly 4. The supporting component 1 includes a receiving space A and a viewing window structure K for observing the receiving space A. The display screen 2 is disposed within the receiving space A and has opposing display surfaces 21 and non-display surfaces 22. The blocking component 3 is disposed within the receiving space A and connected to the display screen 2. The transmission assembly 4 is disposed within the receiving space A and located on the side of the non-display surface 22. The transmission assembly 4 is connected to the display screen 2 and the blocking component 3, and is configured to drive the display screen 2 and the blocking component 3 to move, so that the blocking component 3 or the display screen 2 is positioned opposite the viewing window structure K.

[0054] The supporting component 1 is a hollow structure and includes a receiving space A, which supports the display screen 2, the shielding component 3, and the transmission assembly 4, among other structures. A viewing window structure K is located on the supporting component 1, allowing the user to observe the structure inside the receiving space A. The viewing window structure K can be an open structure or a transparent structure on the supporting component 1; this embodiment does not limit this, as long as the user can observe the receiving space A through the viewing window structure K.

[0055] The display screen 2 is a structure in the display device used to achieve the display effect. The display screen 2 includes a display surface 21 and a non-display surface 22 arranged opposite each other in its thickness direction, wherein the display surface 21 is the side of the display screen 2 that displays image information. The display device includes at least two states: a display state and a non-display state. In the display state, the display screen 2 is arranged opposite to the window structure K. In this embodiment, "the display screen 2 is arranged opposite to the window structure K" means that the user can observe the display screen 2 through the window structure K. Furthermore, since the window structure K is located on one side of the display surface 21 of the display screen 2, when the display device is in the display state, the user can observe the image information displayed on the display screen 2 through the window structure K.

[0056] The shielding member 3 is connected to the display screen 2. The shielding member 3 can be directly connected to the display screen 2, or the connection can be achieved through a structure such as a transmission component 4; this embodiment does not impose any limitations on this. The display screen 2 has two opposing ends in its extension direction, and the shielding member 3 is located at one end of the display screen 2. The display screen 2 and the shielding member 3 can be connected and fixed, or they can be not connected and fixed; this embodiment does not impose any limitations on this. In the non-display state, the shielding member 3 is positioned opposite to the window structure K. The phrase "the shielding member 3 is positioned opposite to the window structure K" in this embodiment means that the user can observe the shielding member 3 through the window structure K. In other words, in the non-display state, the shielding member 3 can block the window structure K, reducing the risk of the user observing other structures within the accommodating space A through the window structure K and improving the viewing experience in the non-display state.

[0057] The transmission component 4 is located on the non-display surface 22 side, that is, on the side of the display screen 2 facing away from the viewing window structure K. The transmission component 4 is connected to at least one of the display screen 2 and the blocking member 3, and the connection method includes, but is not limited to, bonding, welding, and bolting. The transmission component 4 can drive the display screen 2 and the blocking member 3 to move synchronously, so that the display screen 2 and the blocking member 3 are respectively positioned opposite to the viewing window structure K, thereby realizing the switching of the display device in display mode and non-display mode.

[0058] Specifically, the display device provided in this application embodiment can realize mode switching. When it is in the display state and needs to display screen information, the transmission component 4 drives the display screen 2 to be positioned relative to the window structure K; and when it is in the non-display state and does not need to display screen information, the transmission component 4 drives the blocking component 3 to be positioned relative to the window structure K.

[0059] The specific form of the transmission component 4 is not limited in this application embodiment, as long as the transmission component 4 can drive the display screen 2 and the blocking member 3 to move, so that the blocking member 3 and the display screen 2 are respectively arranged opposite to the window structure K in different states. Furthermore, the transmission component 4 can be driven by electric means or by manual means, and this application embodiment is also not limited.

[0060] In the display device provided in this application embodiment, the display screen 2 is located inside the supporting component 1, so the supporting component 1 can protect the display screen 2 to a certain extent. At the same time, when the display screen 2 does not need to display, the blocking component 3 replaces the display screen 2 and is arranged opposite to the window structure K. The display screen 2 is hidden in the accommodating space A and is not affected by external factors, thus further improving the protection of the display screen 2 and thereby improving the display reliability of the display device.

[0061] It should be noted that the specific structure of the supporting component 1 needs to be determined based on the actual use of the display device, and this application embodiment does not impose any limitations. For example, when the display device is used in a vehicle, the supporting component 1 can also be used as a vehicle seat. In other words, the display screen 2 is located inside the vehicle seat. This design reduces the space occupied by the display device inside the vehicle and improves the passenger's riding experience. At the same time, the display screen 2 can also be protected by the vehicle seat, reducing the risk of damage.

[0062] In some embodiments, as shown in Figures 1 to 3, the transmission assembly 4 includes a transmission shaft 41 and a transmission belt 42 that are connected in a transmission manner. The transmission belt 42 is connected to at least one of the display screen 2 and the blocking member 3 to drive the display screen 2 and the blocking member 3 to move.

[0063] The drive shaft 41 and the drive belt 42 are configured to cooperate. The rotation of the drive shaft 41 can drive the drive belt 42 to move relative to it. The drive belt 42 is connected to at least one of the display screen 2 and the shielding member 3. The connection method includes, but is not limited to, bonding, welding and bolting. The display screen 2 and the shielding member 3 are arranged side by side in the extension direction of the drive belt 42. The display screen 2 and the shielding member 3 can be arranged adjacent to each other or spaced apart.

[0064] In this embodiment, the transmission belt 42 can drive the blocking member 3 and the display screen 2 to move synchronously, so that the blocking member 3 and the display screen 2 are respectively arranged opposite to the window structure K, so as to realize the switching of the display device in display state and non-display state.

[0065] It should be noted that the number and structure of the drive shaft 41 and the drive belt 42 are not limited in this embodiment. The number of drive shafts 41 can be one or more, and the drive belt 42 can form a closed loop structure or it can not be a closed loop structure. Furthermore, the drive belt 42 can extend and move in a straight line, or it can extend and move with a certain curvature; this embodiment does not limit these possibilities.

[0066] In some embodiments, as shown in Figures 1 to 3, the transmission belt 42 has a first surface M1 in its own thickness direction, and at least one of the display screen 2 and the shielding member 3 is disposed on the first surface M1.

[0067] The first surface M1 serves as the support surface for the transmission belt 42. The first surface M1 can be used to connect and fix at least one of the display screen 2 and the shielding member 3 to the transmission belt 42, and to provide a certain support effect to at least one of the display screen 2 and the shielding member 3. At least one of the display screen 2 and the shielding member 3 can be fixed to the first surface M1 by adhesive bonding or other methods.

[0068] In some embodiments, referring to FIG4, at least one of the display screen 2 and the shielding member 3 is disposed at at least one end of the transmission belt 42 in its own extending direction. The transmission belt 42 has two opposite ends in its own extending direction, and the display screen 2 and the shielding member 3 can be disposed on either end of the transmission belt 42. Exemplarily, the display screen 2 and the shielding member 3 are respectively disposed at both ends of the transmission belt 42 in its own extending direction, and the display screen 2, the shielding member 3, and the transmission belt 42 together form a closed loop structure.

[0069] In some embodiments, referring to Figures 5 and 6, the drive shaft 41 is provided with a gear structure 411, and the drive belt 42 is provided with a rack structure 421 on the side opposite to the display screen 2. The drive shaft 41 and the drive belt 42 mesh and transmit power. The gear structure 411 on the drive shaft 41 and the rack structure 421 on the drive belt 42 are matched and meshed with each other, thereby realizing the transmission function between the drive shaft 41 and the drive belt 42.

[0070] In this embodiment, the transmission function between the transmission shaft 41 and the transmission belt 42 is achieved through the cooperation of the gear structure 411 and the rack structure 421. This design can improve the transmission reliability of the transmission component 4 and ensure that when the transmission shaft 41 rotates, the transmission belt 42 can move synchronously with the display screen 2 and the shielding member 3, so as to realize the switching of the display device in the display state and the non-display state.

[0071] In some embodiments, there are multiple drive shafts 41, which are arranged side by side in the extension direction of the drive belt 42.

[0072] This design can further improve the transmission reliability between the drive shaft 41 and the drive belt 42, and reduce the risk of slippage and misalignment between the drive shaft 41 and the drive belt 42. Optionally, multiple drive shafts 41 are symmetrically distributed within the accommodating space A.

[0073] In some embodiments, as shown in FIG5, the transmission assembly 4 further includes a drive member 43, which is connected to the transmission shaft 41 and drives the transmission shaft 41 to rotate.

[0074] The driving component 43 is used to automatically switch the display device between display and non-display states. Specifically, the output end of the driving component 43 is connected to the drive shaft 41, causing the drive shaft 41 to rotate. The drive shaft 41 then drives the drive belt 42 to move, causing the drive belt 42 to move the display screen 2 or the blocking component 3 relative to the window structure K, thereby realizing the switching between display and non-display states. Exemplarily, the driving component 43 includes, but is not limited to, structures such as a drive motor and a rotary cylinder.

[0075] This application embodiment enables the display device to switch between display and non-display states by setting a driver 43, thereby improving the automation level of the display device and enhancing the user experience.

[0076] In some embodiments, please refer to Figures 5 and 6. The display device further includes a limiting member 5 disposed in the receiving space A and fixedly connected to the supporting member 1. The limiting member 5 includes a sliding groove structure 51, and at least one of the transmission belt 42, the display screen 2 and the blocking member 3 is located in the sliding groove structure 51.

[0077] The limiting component 5 is fixed to the bearing component 1, meaning that the limiting component 5 will not undergo relative displacement with respect to the bearing component 1. Furthermore, the sliding groove structure 51 in the limiting component 5 also remains fixed relative to the bearing component 1.

[0078] The chute structure 51 is used to limit the movement trajectory of the display screen 2 and the shielding member 3. As mentioned above, the transmission belt 42, the display screen 2, and the shielding member 3 move synchronously. Therefore, controlling the movement trajectory of only one of them is sufficient to simultaneously limit the movement trajectories of the other two. Based on this, in this embodiment, at least one of the transmission belt 42, the display screen 2, and the shielding member 3 is located within the chute structure 51. The extending direction of the chute structure 51 is the movable direction of the transmission belt 42, the display screen 2, and the shielding member 3.

[0079] This embodiment of the application sets up a sliding groove structure 51 to restrict the movement direction of the display screen 2 and the blocking member 3, so as to ensure that the display screen 2 can be better positioned relative to the window structure K in the display state; and to ensure that the blocking member 3 can be better positioned relative to the window structure K in the non-display state, thereby improving the reliability of the display device during the switching process between the display state and the non-display state.

[0080] It should be noted that at least one of the transmission belt 42, display screen 2 and shielding member 3 mentioned in the embodiments of this application is located within the slide groove structure 51. This can mean that a portion of the structure of at least one of the transmission belt 42, display screen 2 and shielding member 3 is located within the slide groove structure 51, or that all of the structure of at least one of the transmission belt 42, display screen 2 and shielding member 3 is located within the slide groove structure 51. The embodiments of this application do not impose any restrictions on this.

[0081] In some embodiments, please refer to Figures 7 to 9, the transmission belt 42 includes a protrusion 422 that extends beyond the display screen 2 in a first direction X. The protrusion 422 is at least partially located within the groove structure 51, and the first direction X intersects the extension direction of the transmission belt 42.

[0082] The protrusion 422 in the transmission belt 42 extends beyond at least one side of the display screen 2 in a first direction X, where the first direction X can be the width direction of the display screen 2. For example, the transmission belt 42 extends beyond both sides of the display screen 2 in the first direction X, that is, two protrusions 422 are provided, and the two protrusions 422 are respectively located on both sides of the display screen 2 in the first direction X.

[0083] In this embodiment, since the protrusion 422 is at least partially located within the slide groove structure 51, the slide groove structure 51 can restrict the movement path of the transmission belt 42, the display screen 2, and the blocking member 3 through the protrusion 422. Furthermore, since the protrusion 422 protrudes beyond the display screen 2, it prevents the display screen 2 from being located within the slide groove structure 51, thereby reducing the risk of contact between the display screen 2 and the slide groove structure 51, i.e., reducing the risk of friction and impact on the display screen 2, and improving the reliability and service life of the display device.

[0084] In some alternative embodiments, the protrusion 422 extends beyond the shield 3 in the first direction X. Similar to the display screen 2, this design also prevents the shield 3 from being located within the groove structure 51, thereby reducing the risk of friction and impact on the shield 3. Optionally, the dimensions of the shield 3 in the first direction X are the same as the dimensions of the display screen 2 in the first direction X.

[0085] In some embodiments, please refer to Figures 6 and 7. The slide structure 51 includes a first limiting groove 511 and a second limiting groove 512 that are interconnected. The first limiting groove 511 includes a straight line segment 511a that is disposed opposite to the window structure K.

[0086] The straight segment 511a in the first limiting groove 511 is positioned opposite to the window structure K. Therefore, when the display screen 2 is located within the straight segment 511a, it indicates that the display device is in display mode; and when the blocking member 3 is located within the straight segment 511a, it indicates that the display device is in non-display mode. Furthermore, in display mode, the display screen 2 can maintain a horizontal image under the influence of the straight segment 511a, thereby improving the display effect of the display device.

[0087] The second limiting groove 512 is connected to the first limiting groove 511, and the second limiting groove 512 is used to hide the obstruction member 3 or the display screen 2. Specifically, in the display state, the display screen 2 is located within the first limiting groove 511 and is positioned opposite to the window structure K to achieve the display effect of the display device. At this time, the obstruction member 3 is located within the second limiting groove 512, and the second limiting groove 512 hides the obstruction member 3 to reduce the risk of it being observed by the user. In the non-display state, the second limiting groove 512 hides the display screen 2, thereby reducing the risk of the display screen 2 being bumped or knocked.

[0088] In some embodiments, the second limiting groove 512 has a curling tendency.

[0089] As described above, the second limiting groove 512 is used to conceal the obstruction member 3 or the display screen 2. Furthermore, in this embodiment, the second limiting groove 512 is configured to have a curving tendency; that is, at least a portion of the second limiting groove 512 does not continue to extend along the extension direction of the straight segment 511a, but extends with a certain curvature. This design can reduce the overall size of the assembly consisting of the transmission belt 42, the display screen 2, and the obstruction member 3 in the extension direction of the straight segment 511a, thereby reducing the size of the display device in the extension direction of the straight segment 511a.

[0090] In some embodiments, as shown in FIG8, the second limiting groove 512 includes an arc-shaped segment 512a. The presence of the arc-shaped segment 512a can reduce the size of the display device in the extension direction of the straight segment 511a. Furthermore, compared to a solution where the second limiting groove 512 includes a multi-layer winding structure, the arc-shaped segment can reduce the degree of curvature of the display screen 2, thereby reducing the stress on the display screen 2 in the non-display state and improving the service life of the display screen 2.

[0091] In some embodiments, there are two second limiting grooves 512, which are located on both sides of the first limiting groove 511.

[0092] Two limiting grooves are located on both sides of the first limiting groove 511 and are interconnected with it. One limiting groove can be used to hide the blocking member 3 in the display state, while the other limiting groove can be used to block the display screen 2 in the non-display state. Optionally, two second limiting grooves 512 are symmetrically distributed on both sides of the first limiting groove 511.

[0093] In some embodiments, as shown in Figures 5 to 7, the second limiting groove 512 has a first end D1 and a second end D2 opposite to each other in its extending direction, and the first end D1 is in communication with the first limiting groove 511. The limiting member 5 also includes a stop structure 52, which is disposed at the second end D2 to limit the movement of the display screen 2 or the blocking member 3.

[0094] The first end D1 and the second end D2 are the two ends of the second limiting groove 512, respectively. The first end D1 is used to connect with the first limiting groove 511. The extension length of the second limiting groove 512 is the total extension length of the second limiting groove 512 from the first end D1 to the second end D2. Optionally, the extension length of the second limiting groove 512 is greater than or equal to the extension length of the display screen 2, so that in the non-display state, the second limiting groove 512 can completely accommodate the display screen 2.

[0095] A stop structure 52 is disposed at the second end D2. The shape of the stop structure 52 is not limited in this embodiment. Exemplarily, the stop structure 52 is a plate-like structure and can close the second end D2 of the second limiting groove 512. The presence of the stop structure 52 can prevent the blocking member 3 from disengaging from the second limiting groove 512 in the display state; or prevent the display screen 2 from disengaging from the second limiting groove 512 in the non-display state, thereby improving the reliability of the cooperation between the limiting member 5, the display screen 2, and the blocking member 3, and enabling long-term use of the display device.

[0096] In some embodiments, as shown in FIG6, the transmission belt 42 has a first surface M1 in its own thickness direction, the display screen 2 is disposed on the first surface M1, and a portion of the structure in the first surface M1 is recessed inward to form a recessed portion 44.

[0097] The first surface M1 is located on the side of the transmission belt 42 facing the display screen 2. The display screen 2 can be connected and fixed to the first surface M1 to achieve synchronous movement of the display screen 2 and the transmission belt 42. At the same time, the first surface M1 also provides support for the display screen 2. The recessed portion 44 is formed by the first surface M1 recessed in a direction away from the display screen 2. The presence of the recessed portion 44 can reduce the structural strength of some positions in the transmission belt 42, thereby enabling it to bend and deform together with the display screen 2, so that the display screen 2 can more easily enter the second limiting groove 512. The number, size and position of the recessed portions 44 are not limited in the embodiments of this application.

[0098] In some embodiments, the drive belt 42 comprises at least one of ABS plastic and TPU materials.

[0099] ABS plastic is a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S). ABS plastic combines the common properties of the three components. Acrylonitrile makes it resistant to chemical corrosion and heat, and has a certain surface hardness. Butadiene gives it high elasticity and toughness. Styrene gives it the processing and molding characteristics of thermoplastic plastics and improves its electrical properties.

[0100] ABS plastic itself has a certain strength, thus ensuring the support of the transmission belt 42 for the display screen 2. Simultaneously, the presence of the recessed portion 44 allows the transmission belt 42 to accommodate bending requirements. In summary, the transmission belt 42 provided in this embodiment can ensure its support effect on the display screen 2 while satisfying bending deformation requirements, improving the reliability of the display device during the switching process between display and non-display states.

[0101] TPU is a type of elastomer that can be plasticized by heat and dissolved by solvents, possessing excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. Similar to ABS plastic, the use of TPU material allows the transmission belt 42 to maintain its support for the display screen 2 while still being able to bend and deform.

[0102] In some embodiments, there are multiple recesses 44, which are arranged side by side in the extending direction of the transmission belt 42.

[0103] In this embodiment, the design of multiple recesses 44 can further improve the bending capacity of the transmission belt 42. The dimensions of the multiple recesses 44 can be the same or different, and the spacing between adjacent recesses 44 can be the same or different. For example, the recess depth of each recess 44 is the same, and the spacing between any two adjacent recesses 44 remains consistent.

[0104] As described above, a rack structure 421 can be provided on the side of the transmission belt 42 facing away from the display screen 2. Further optionally, multiple racks in the rack structure 421 are spaced apart, with the gaps between adjacent racks corresponding to the recesses 44. This design can further reduce the structural strength of the transmission belt 42 at the corresponding positions of the recesses 44, thereby making the transmission belt 42 easier to bend and deform.

[0105] In some embodiments, as shown in Figures 5 and 6, the transmission assembly 4 further includes an adhesive portion 45 for connecting the transmission belt 42 and the display screen 2, wherein the adhesive portion 45 is offset from the recessed portion 44.

[0106] Since both the display screen 2 and the transmission belt 42 have a certain thickness, their bending degrees are not exactly the same during the bending deformation process. If the entire display screen 2 is connected and fixed to the transmission belt 42 at this time, some of the stress inside the display screen 2 may not be released in time, leading to display problems.

[0107] In this embodiment, the adhesive portion 45 connecting the transmission belt 42 and the display screen 2 is misaligned with the recessed portion 44. Specifically, no adhesive portion 45 is provided between the transmission belt 42 and the display screen 2 at the corresponding position of the recessed portion 44. Consequently, at the corresponding position of the recessed portion 44, the transmission belt 42 and the display screen 2 can undergo relative displacement to a certain extent, thereby effectively releasing stress and reducing the risk of display problems.

[0108] In some embodiments, as shown in Figures 6 to 8, the transmission belt 42 includes a body portion 423 and a protrusion 422 including a roller 424, the roller 424 being rotatably connected to the body portion 423.

[0109] As can be seen from the foregoing, since the protrusion 422 protrudes from the display screen 2, it can prevent the display screen 2 from being located inside the sliding groove structure 51, thereby reducing the risk of the display screen 2 coming into contact with the sliding groove structure 51, that is, reducing the risk of the display screen 2 being rubbed or bumped.

[0110] Based on this, in this embodiment, the protrusion 422 includes a roller 424. The roller 424 is at least partially located within the slide groove structure 51 and rotatably connected to the main body 423. The roller 424 can contact the inner wall of the first limiting groove 511 or the second limiting groove 512. The roller 424 improves the smoothness of the transmission belt 42 when moving relative to the slide groove structure 51, allowing the display device to smoothly transition between display and non-display states. Furthermore, the roller 424 reduces the contact friction between the transmission belt 42 and the slide groove structure 51, improving the service life of the display device.

[0111] In some embodiments, there are multiple rollers 424, which are disposed on both sides of the transmission belt 42 in the first direction X and arranged side by side in the extending direction of the transmission belt 42.

[0112] This application embodiment further improves the smoothness of the transmission belt 42 when moving relative to the slide structure 51 by setting multiple rollers 424, so that the display device can smoothly transition between display state and non-display state.

[0113] In some embodiments, as shown in Figures 7 and 9, the limiting member 5 includes a first limiting portion 53 and a second limiting portion 54 located on both sides of the display screen 2 in the first direction X, and a connecting portion 55 connecting the first limiting portion 53 and the second limiting portion 54. The first limiting portion 53 is provided with a sliding groove structure 51, and the drive shaft 41 is disposed between the first limiting portion 53 and the second limiting portion 54.

[0114] The display screen 2 is sandwiched between the first limiting part 53 and the second limiting part 54 in the first direction X. The first limiting part 53 and the second limiting part 54 can limit the relative position of the display screen 2 in the first direction X, so as to ensure that the center of the window structure K can be aligned with the center of the display screen 2 in the display state, thereby improving the display effect of the display device. For example, at least one of the first limiting part 53 and the second limiting part 54 can be fixedly connected to the supporting member 1 by means of adhesive or the like.

[0115] Furthermore, since the sliding groove structure 51 is provided on the first limiting part 53, the first limiting part 53 can also restrict the movement path of the display screen 2 and the blocking member 3 during the state switching of the display device. For example, the sliding groove structure 51 is formed by recessing the surface of the first limiting part 53 toward the second limiting part 54 in a direction away from the second limiting part 54. Optionally, the second limiting part 54 is also provided with a sliding groove structure 51.

[0116] The connecting part 55 is connected to the first limiting part 53 and the second limiting part 54 respectively to ensure that the relative positions of the first limiting part 53 and the second limiting part 54 remain fixed. The connecting part 55 can be fixed to the first limiting part 53 and the second limiting part 54 by means of bonding, welding or bolting. There can be one or more connecting parts 55. Optionally, the connecting parts 55 are staggered from the window structure K, that is, the user cannot observe the connecting parts 55 through the window structure K.

[0117] In some embodiments, the drive shaft 41 is disposed between the first limiting portion 53 and the second limiting portion 54.

[0118] The first limiting part 53 and the second limiting part 54 are located on both sides of the display screen 2, that is, the first limiting part 53 and the second limiting part 54 are spaced apart, and there is a certain space between them. Based on this, in this embodiment, the drive shaft 41 is arranged between the first limiting part 53 and the second limiting part 54, thereby realizing the effective use of space and improving space utilization. Further optionally, there are two connecting parts 55, and the drive shaft 41 is arranged between the two connecting parts 55.

[0119] In some embodiments, as shown in FIG5, the supporting component 1 includes a hollow housing 11, an accommodating space A located inside the housing 11, and a display screen 2 at least partially conforming to the inner wall 111 of the housing and adapted to the shape of the inner wall 111 of the housing.

[0120] The outer casing 11 houses the display screen 2, the shielding component 3, and the transmission assembly 4, among other structures. The viewing window structure K is located on the outer casing 11. In the display state, the user can observe the display screen 2 through the viewing window structure K. However, if the display screen 2 is spaced apart from the inner wall 111 of the outer casing, the user might observe other structures within the accommodating space A through the area between the display screen 2 and the inner wall 111, resulting in a decreased viewing experience. Therefore, in this embodiment, the display screen 2 is fitted to the inner wall 111 of the outer casing and its shape matches that of the inner wall 111. This ensures that in the display state, there is no gap or a small gap between the display screen 2 and the inner wall 111, thereby ensuring the display effect of the display device.

[0121] In some alternative embodiments, the shielding member 3 is at least partially attached to the inner wall 111 of the housing and is adapted to the shape of the inner wall 111 of the housing.

[0122] In some embodiments, the surface of the shield 3 facing away from the transmission assembly 4 is the same color as the outer surface of the housing 11.

[0123] In the non-display state, the obstruction 3 is positioned opposite the viewing window structure K, and the user can observe the obstruction 3 through the viewing window structure K. Based on this, in this embodiment, the surface color of the obstruction 3 facing away from the transmission assembly 4 is set to be the same as the outer surface color of the housing 11. That is, in the non-display state, the color observed by the user through the viewing window structure K is the same as the color of the housing 11, thereby better achieving the concealment of the display screen 2 and improving the observation effect of the display device in the non-display state.

[0124] In some embodiments, the window structure K is an opening provided on the housing 11, and the material of the shield 3 is the same as the material of at least a portion of the structure in the housing 11. This design allows the tactile feel of the window structure K to be consistent with that of the housing 11 when not in display mode. For example, when the display device is used in a vehicle, the supporting component 1 also serves as a vehicle seat, and the materials of the housing 11 and the shield 3 are the same as the seat material, thereby improving the tactile feel for passengers.
