Description

Display housing, display device and vehicle display Technical Field

[0001] This disclosure relates to the field of display technology, and more specifically, to a display housing, a display device, and an in-vehicle display. Background Technology

[0002] Current in-vehicle displays generally employ either a single display screen or a long, rectangular screen composed of multiple screens. For single-screen displays, due to the smaller display area, the screen height can be set slightly above the dashboard level while ensuring safe driving. For long, rectangular screen displays, due to the larger display area, the screen height needs to be set slightly below the dashboard level to avoid obstructing the driver's view. However, both the small display area of ​​a single screen and the low height of a long, rectangular screen negatively impact user entertainment and reduce user engagement.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0074] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0075] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0076] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0077] Figure 1 illustrates a top view of a display housing 1 according to an embodiment of the present disclosure, and Figure 2 illustrates an axial side bottom view of a sliding housing unfolded according to an embodiment of the present disclosure. As shown in Figures 1 and 2, the display housing 1 includes: a fixed housing 11, two sets of sliding mechanisms, and a first driving system 14. The two sets of sliding mechanisms are respectively located on both sides of the fixed housing 11 in the first direction X, and are slidably connected to the fixed housing 11. Each set of sliding mechanisms includes a sliding housing 12 and a support assembly 13. The sliding housing 12 has a guide groove 123 extending along the first direction X, and the guide groove 123 bypasses the side wall of the sliding housing 12 away from the fixed housing 11. The support assembly 13 has a limiting part 134 (not shown in the figure). 34 is slidably limited within the guide groove 123, and the support component 13 can slide along the guide groove 123 when the sliding housing 12 slides relative to the fixed housing 11; the first drive system 14 includes a first drive motor 141 and two sets of first drive components 142. The first drive motor 141 is fixed on the back of the fixed housing 11, and the two sets of first drive components 142 are connected to the first drive motor 141 and respectively connected to the two sliding housings 12. The first drive motor 141 is used to drive at least one of the two sliding housings 12 to move along the first direction X.

[0078] The front of the fixed housing 11 is used to fix the fixed area of ​​the flexible display screen 2, and the support component 13 is used to fix the sliding area of ​​the flexible display screen 2. Specifically, the flexible display screen 2 includes a fixed area and sliding areas located on both sides of the fixed area in the first direction X. The support components 13 of the two sets of sliding mechanisms are respectively fixedly connected to the sliding areas on both sides of the flexible display screen 2.

[0079] Thus, driven by the first drive motor 141 and driven by at least one set of first drive components 142, at least one sliding housing 12 can slide relative to the fixed housing 11, thereby enabling the support component 13 to slide around the front or back of the sliding housing 12. This allows at least one sliding area on the flexible display screen 2 to slide around to the front or back of the sliding housing 12 along with the support component 13, thereby adjusting the size of the displayable area on the flexible display screen 2. In other words, the sliding housing 12 can be controlled to be in an unfolded state (sliding away from the fixed housing 11 to its limit) or a retracted state (sliding towards the fixed housing 11 to its limit) according to driving and entertainment needs, thereby adjusting the size of the displayable area on the flexible display screen 2. This improves the user's entertainment experience while ensuring safe driving, and thus increases user engagement.

[0080] It should be noted that the front of the fixed housing 11 and the front of the sliding housing 12 refer to the surface located on the light-emitting side of the display housing 1, while the back of the fixed housing 11 and the back of the sliding housing 12 refer to the surface located on the backlight side of the display housing 1.

[0081] Optionally, as shown in Figures 3, 4 or 5, the fixed housing 11 includes a fixed frame 111 and a pair of fixed frames 112. The two fixed frames 112 are respectively fixed on both sides of the fixed frame 111 that are perpendicular to the first direction X, that is, the length direction of the two fixed frames 112 is parallel to the first direction X.

[0082] Optionally, as shown in Figures 3, 4 or 5, the sliding housing 12 includes a sliding frame 121 and a pair of sliding side frames 122. The two sliding side frames 122 are respectively fixed on both sides of the sliding frame 121 that are perpendicular to the first direction X, that is, the length direction of the two sliding side frames 122 is parallel to the first direction X.

[0083] The side wall of the sliding frame 121 away from the fixed housing 11 can be an arc wall to ensure the smoothness of the support component 13 sliding on the sliding housing 12, while reducing the bending curvature of the flexible display screen 2 at the side wall of the sliding housing 12, and avoiding creases in the sliding area of ​​the flexible display screen 2.

[0084] Additionally, as shown in Figure 4 or Figure 5, the sliding housing 12 also includes a back cover 128, which is located on the back side of the sliding frame 121 (i.e., the back side of the sliding housing 12) and is fixedly connected to the sliding frame 122. A gap exists between the back cover 128 and the sliding frame 121 to form an accommodating space, thereby allowing the flexible display screen 2's winding area to be accommodated in the gap between the back cover 128 and the sliding frame 121 when the sliding housing 12 is in the retracted state, while simultaneously protecting the winding area of ​​the flexible display screen 2.

[0085] In this embodiment, the sliding limiting methods of the two sliding housings 12 and the fixed housing 11 included in the two sets of sliding mechanisms can be the same or different. Next, the connection method between a sliding housing 12 and the fixed housing 11 will be explained.

[0086] The relative sliding of the fixed housing 11 and the sliding housing 12 can be a sliding match between the fixed housing 11 and the sliding housing 12 themselves, or a sliding match with the help of a guide mechanism. Of course, it can also be a sliding match combining the two.

[0087] Taking the sliding connection between the fixed housing 11 and the sliding housing 12 as an example, the inner wall of the fixed frame 112 (the surface facing the fixed frame 111) is formed with a groove, and the sliding frame 122 is slidably limited within the groove, thereby realizing the slidable connection between the fixed housing 11 and the sliding housing 12; and / or, one of the fixed frame 111 and the sliding frame 121 has a groove, and the other has a protrusion, which is slidably limited within the groove, thereby realizing the slidable connection between the fixed housing 11 and the sliding housing 12. Of course, other methods can also be used to realize the slidable connection between the fixed housing 11 and the sliding housing 12, and this disclosure does not limit this.

[0088] Taking the sliding matching of the fixed housing 11 and the sliding housing 12 via a guide mechanism as an example, as shown in Figures 2 and 6, the sliding mechanism further includes a first guide mechanism 15, which includes a first slide rail 151 and a first slider 152. The first slider 152 is slidably limited on the first slide rail 151. One of the first slide rail 151 and the first slider 152 is fixedly connected to the fixed housing 11 (fixed frame 111), and the other is fixedly connected to the sliding housing 12 (sliding frame 121). Thus, the slidable connection between the fixed housing 11 and the sliding housing 12 can be achieved by the slidable limitation of the first slider 152 on the first slide rail 151.

[0089] In addition to being fixed on the fixed frame 111 and the sliding frame 121 respectively, the first slide rail 151 and the first slider 152 can also be fixed on the fixed frame 112 and the sliding frame 122 respectively. This disclosure does not limit this.

[0090] In the case where the first slide rail 151 and the first slider 152 are respectively fixed on the fixed frame 111 and the sliding frame 121, optionally, as shown in Figures 2 and 6, the sliding frame 121 includes a frame body 125 and a first connecting bridge 126. The first connecting bridge 126 is fixed on the frame body 125 and is located on the back side of the fixed frame 111 (i.e., the back side of the fixed housing 11), with a gap between it and the back side of the fixed frame 111 (i.e., the surface near the back side of the fixed housing 11). Thus, the first slide rail 151 and the first slider 152 can be positioned between the first connecting bridge 126 and the fixed frame 111, with the first slide rail 151 fixedly connected to the fixed frame 111 and the first slider 152 fixedly connected to the first connecting bridge 126, thereby achieving a sliding connection between the frame body 125 and the fixed frame 111, that is, a sliding connection between the sliding housing 121 and the fixed housing 11.

[0091] It should be noted that the first guide mechanism 15 can be a sliding fit structure between the first slide rail 151 and the first slider 152, or it can be other forms of sliding fit structure, such as a sliding fit structure guided by a transmission belt, etc. This disclosure does not limit this type of sliding fit structure.

[0092] In some embodiments, for the slidingly fitted fixed housing 11 and sliding housing 12, as shown in FIG1 or FIG3, the edge portion of the fixed housing 11 (i.e. the fixed frame 111) has a first comb tooth structure 113, and the edge portion of the sliding housing 12 (i.e. the sliding frame 121) has a second comb tooth structure 124, and the first comb tooth structure 113 and the second comb tooth structure 124 mesh.

[0093] Thus, when the sliding housing 12 is in the unfolded position (i.e., the sliding housing 12 slides to its limit position in the direction away from the fixed housing 11), the flexible display screen 2 can be supported by the first comb tooth structure 113 and the second comb tooth structure 124 at the same time, so as to increase the support area of ​​the display housing 1 on the flexible display screen 2 in the first direction X, thereby facilitating the improvement of the flatness of the displayable area on the flexible display screen 2.

[0094] The edge of the fixed housing 11 is the edge of the fixed housing 11 on one side in the first direction X, and the edge of the sliding housing 12 is the edge of the sliding housing 12 that slides and engages with the fixed housing 11 in the first direction X.

[0095] In conjunction with the sliding engagement of the fixed frame 111 and the sliding frame 121 described above, one of the sidewalls of the two meshing comb teeth in the first comb tooth structure 113 and the second comb tooth structure 124 may have a sliding groove and the other may have a protrusion; and / or one of the sidewalls of the two comb teeth may be fixedly provided with a first slide rail 151 and the other may be fixedly provided with a first slider 152, so as to realize the relative sliding of the fixed housing 11 and the sliding housing 12.

[0096] In this embodiment of the disclosure, the first drive motor 141 included in the first drive system 14 can be a dual-head motor to realize the synchronous transmission of the two sets of first drive components 142, thereby driving the two sliding housings 12 to slide synchronously relative to the fixed housing 11; of course, the first drive motor 141 can also include two sub-motors, which are respectively connected to the two sets of first drive components 142, so that the sliding of one sliding housing 12 relative to the fixed housing 11 can be realized by one sub-motor alone; or the two sliding housings 12 can be synchronously slid relative to the fixed housing 11 by two sub-motors.

[0097] In the case where the first drive motor 141 includes two sub-motors, the two sub-motors can be arranged back-to-back or facing away from each other and staggered. Furthermore, the first drive motor 141 is fixed to the back of the fixed housing 11, and in conjunction with the fixed frame 111 included in the fixed housing 11, the first drive motor 141 is fixed to the back of the fixed frame 111. In this case, the first drive motor 141 is directly fixed to the back of the fixed housing 11 (fixed frame 111), or as shown in Figure 2 or Figure 5, a mounting bracket 16 is provided on the back of the fixed housing 11 (fixed frame 111), and the first drive motor 141 is fixed to the mounting bracket 16. Thus, the installation of the mounting bracket 16 improves the stability of the first drive motor 141 fixed to the fixed housing 11.

[0098] Furthermore, there can be one first drive motor 141, which is fixed to the back of the fixed housing 11 and centered in a direction perpendicular to the first direction X, in order to ensure the stability of the sliding housing 12 during sliding. Of course, there can be multiple first drive motors 141, that is, the display housing 1 includes multiple first drive systems 14, in which case the multiple first drive motors 141 are distributed along a direction perpendicular to the first direction X and are all fixed to the back of the fixed housing 11.

[0099] The first drive system 14 includes two sets of first drive components 142. The structures of the two sets of first drive components 142 can be the same or different, as long as they can drive the two sliding housings 12 to slide relative to the fixed housing 11.

[0100] In some embodiments, as shown in Figures 2 and 7, the first drive assembly 142 includes a transmission screw 143 and a fixed screw block 144. One end of the transmission screw 143 is fixedly connected to the main shaft of the first drive motor 141, and the transmission screw 143 is arranged along a first direction X. The fixed screw block 144 is fixed on the sliding housing 12 and screwed to the transmission screw 143. Thus, when the first drive motor 141 drives the transmission screw 143 to rotate, based on the screwed engagement between the fixed screw block 144 and the transmission screw 143, the fixed screw block 144 can move along the length direction of the transmission screw 143, thereby realizing the relative sliding between the sliding housing 12 and the fixed housing 11.

[0101] Regarding the fixing of the fixing screw block 144 on the sliding housing 12, the fixing screw block 144 can be fixed on the sliding frame 122 of the sliding housing 12, or it can be fixed on the end face of the sliding housing 12 facing the fixed housing 11. Of course, as shown in Figures 2 and 7, the sliding frame 121 includes a frame body 125 and a second connecting bridge 127. The second connecting bridge 127 is fixed on the frame body 125 and is located on the back side of the fixed frame 111, with a gap between it and the back side of the fixed frame 111. The transmission screw 143 is located there. In this way, the transmission screw 143 and the fixing screw block 144 can be set between the second connecting bridge 127 and the fixed frame 111, and the fixing screw block 144 is fixed on the second connecting bridge 127 to realize the transmission connection between the first drive assembly 142 and the frame body 125, thereby realizing the sliding of the sliding housing 12 relative to the fixed housing 11 under the drive of the first drive motor 141.

[0102] Optionally, as shown in Figure 7, the first drive assembly 142 further includes a support frame 145, which is fixed to the fixed housing 11, and the end of the transmission screw 143 away from the first drive motor 141 is fixedly connected to the support frame 145. Thus, by supporting the end of the transmission screw 143 with the support frame 145, the stability of the transmission screw 143 is ensured, and jamming that occurs when the sliding housing 12 slides relative to the fixed housing 11 due to the drooping end of the transmission screw 143 is avoided.

[0103] Optionally, as shown in Figure 7, the first drive assembly 142 further includes a limiting rod 146, which is arranged parallel to the transmission screw 143. The limiting rod 146 passes through the fixed screw block 144 and is fixed to the fixed housing 11. In this way, the limiting rod 146 can prevent the fixed screw block 144 and the transmission screw 143 from rotating synchronously.

[0104] It should be noted that the first drive component 142 can be a screw drive structure or other types of structures, such as a belt drive structure, and this disclosure does not limit this type of structure.

[0105] In this embodiment of the present disclosure, when the first drive motor 141 drives the sliding housing 12 to slide relative to the fixed housing 11, in order to ensure that the sliding housing 12 can stop after sliding to its limit position, in some embodiments, in conjunction with the sliding engagement of the slide groove and the protrusion, or the sliding engagement of the first slide rail 151 and the first slider 152, a stop switch can be provided at the end of the slide groove or the end of the first slide rail 151, and the stop switch is connected to the first drive motor 141. In this way, when the sliding housing 12 slides to its limit position, the stop switch can be triggered by the protrusion or the first slider 152, and then the first drive motor 141 will stop driving after receiving the corresponding trigger signal, so as to achieve timely stopping of the sliding housing 12.

[0106] In other embodiments, the first drive system 14 further includes a Hall detection circuit, and a magnetic component is fixed on the sliding housing 12; the Hall detection circuit is fixed on the back of the fixed housing 11 and electrically connected to the first drive motor 141. The Hall detection circuit is used to detect the magnetic flux of the magnetic component, and when the magnetic flux is greater than a preset value, the first drive motor 141 controls the sliding housing 12 to stop sliding.

[0107] The Hall effect detection circuit is located on the edge of the fixed housing 11 that slides against the sliding housing 12, and the magnetic component is located on the edge of the sliding housing 12 that slides against the fixed housing 11. The magnetic component is closer to the midpoint of the fixed housing 11 in the first direction X than the Hall effect detection circuit. Thus, when the first drive motor 141 drives the sliding housing 12 to slide relative to the fixed housing 11, the distance between the Hall effect detection circuit fixed on the fixed housing 11 and the magnetic component on the sliding housing 12 decreases, causing the magnetic flux detected by the Hall effect detection circuit to increase. When the magnetic flux detected by the Hall effect detection circuit exceeds a preset value, a stop signal is generated, and the first drive motor 141 stops driving upon receiving the corresponding stop signal, thereby achieving timely stopping of the sliding housing 12.

[0108] It should be noted that, in addition to the two methods described above for timely stopping of the sliding housing 12, other methods can also be used. For example, a distance sensor is provided on the back of the fixed housing 11, and the distance sensor is electrically connected to the first drive motor 141. Thus, the distance sensor can detect the sliding distance of the sliding housing 12 relative to the fixed housing 11, and when it is determined that the sliding distance of the sliding housing 12 relative to the fixed housing 11 is equal to a preset value, a stop signal is generated. Subsequently, the first drive motor 141 stops driving after receiving the corresponding stop signal, thereby achieving timely stopping of the sliding housing 12.

[0109] In this embodiment of the disclosure, the support component 13 is slidably limited on the sliding housing 12 so that when the sliding housing 12 slides relative to the fixed housing 11, the support component 13 can slide relative to the sliding housing 12, so that the sliding area of ​​the flexible display screen 2 can switch between the front and back of the sliding housing 12, thereby realizing the adjustment of the size of the displayable area on the flexible display screen 2.

[0110] Specifically, due to the fixation of the support component 13 to the sliding area on the flexible display screen 2, and the fixation of the fixed area on the flexible display screen 2 to the fixed housing 11, when the sliding housing 12 slides away from the fixed housing 11, the flexible display screen 2 limits the support component 13, that is, the part of the support component 13 located on the front of the sliding housing 12 remains stationary, thereby facilitating the gradual sliding of the part of the support component 13 located on the back of the sliding housing 12 to the front of the sliding housing 12, so as to increase the displayable area of ​​the flexible display screen 2; while when the sliding housing 12 slides towards the fixed housing 11, based on the flatness of the flexible display screen 2 and the sliding nature of the eye guide groove 123 of the support component 13, the part of the support component 13 away from the fixed housing 11 slides to the back of the sliding housing 12, so as to reduce the displayable area of ​​the flexible display screen 2.

[0111] At least a portion of the support component 13 is located on the front side of the sliding housing 12 (the side closest to the front side of the fixed housing 11) to ensure that the flexible display screen 2 can be fixed on the front side of the fixed housing 11, while ensuring the flatness of the displayable area on the flexible display screen 2. In addition, at least a portion of the support component 13 is also located on the back side of the sliding housing 12 to ensure that when the sliding housing 12 slides toward the fixed housing 11, the support component 13 can slide around to the back side of the sliding housing 12.

[0112] In conjunction with the above-described case where the sliding housing 12 includes a sliding frame 121 and a sliding side frame 122, for the sliding limit of the support component 13 on the sliding housing 12, as shown in Figures 8 and 9, the guide groove 123 is located on the sliding frame 121, or as shown in Figures 8 and 10, the guide groove 123 is located on the inner wall of the sliding side frame 122 (i.e., the side surface of the sliding side frame 122 facing the sliding frame 121); of course, it is also possible that both the inner walls of the sliding frame 121 and the sliding side frame 122 have guide grooves 123.

[0113] In the case where the sliding frame 122 has a guide groove 123, both sliding frames 122 included in the sliding housing 12 may have guide grooves 123, or one of the two sliding frames 122 may have guide grooves 123. This disclosure does not limit this.

[0114] Optionally, the cross-section of the guide groove 123 can be L-shaped or an inverted T-shaped, etc., and the cross-section of the guide groove 123 is perpendicular to the extension direction of the guide groove 123. Of course, the cross-section of the guide groove 123 can also be other shapes, such as trapezoids, as long as it can cooperate with the limiting part 134 to limit the limiting part 134. In addition, in order to further reduce the thickness of the sliding frame 122 (i.e., the dimension in the direction perpendicular to the front of the fixed housing 11), the cross-section of the guide groove 123 can also be set to be linear. In this case, the edge of the support assembly 13 parallel to the first direction X is directly inserted into the guide groove 123 to achieve the limiting.

[0115] When the sliding frame 121 is provided with guide grooves 123, one guide groove 123 can be provided on the sliding frame 121, or multiple guide grooves 123 can be provided as shown in Figure 8. When the sliding frame 121 has multiple guide grooves 123, the corresponding support component 13 has a limiting part 134 corresponding to each guide groove 123. Thus, the stability of the support component 13 in the upper limit position of the sliding housing 12 is improved by the multiple guide grooves 123 and the limiting part 134 corresponding to each guide groove 123, thereby improving the stability of the flexible display screen 2 fixed on the display housing 1.

[0116] The guide groove 123 can be integrally formed on the sliding frame 121, or it can be a structural component with the guide groove 123 fixed to the sliding frame 121. Furthermore, the cross-section of the guide groove 123 is L-shaped, or an inverted T-shaped, etc., and the cross-section of the guide groove 123 is perpendicular to its extension direction. Of course, the cross-section of the guide groove 123 can also be other shapes, such as trapezoidal, as long as it can cooperate with the limiting part 134 to limit the movement of the limiting part 134.

[0117] It should be noted that, in conjunction with the above-described case where the sliding housing 12 has a second comb tooth structure 124, the guide groove 123 on the sliding frame 121 can be located on the comb teeth included in the second comb tooth structure 124. In this case, at least one comb tooth included in the second comb tooth structure 124 can have a guide groove 123.

[0118] In some embodiments, as shown in Figures 1, 8, and 9, or Figures 1, 8, and 10, the support assembly 13 includes a plurality of connecting rods 131 spaced apart in sequence. Each connecting rod 131 includes a rod body 132, a connecting block 133, and a limiting part 134. The length direction of the rod body 132 is perpendicular to the first direction X. The connecting block 133 is fixedly connected to the rod body 132, and the limiting part 134 is fixedly connected to the connecting block 133. The limiting part 134 extends out of the connecting block 133 in the length direction of the rod body 132. Thus, when the limiting part 134 extends out of the connecting block 133, the rod body 132 can be limited on the sliding housing 12 by the sliding limitation of the limiting part 134 in the guide groove 123, while the rod body 132 can slide along the guide groove 123, thereby realizing the sliding of the support assembly 13 on the sliding housing 12.

[0119] The support assembly 13 includes multiple rods 132 that can be independently arranged. Alternatively, the multiple rods 132 can be connected sequentially via connectors, as long as they can be connected and bend along the side wall of the sliding housing 12 away from the fixed housing 11. For the independently arranged multiple rods 132, they can be connected sequentially by fixing them to the sliding area on the flexible display screen 2. Furthermore, the multiple rods 132 in the support assembly 13 can be arranged close together, so that when the sliding housing 12 slides towards the fixed housing 11, the mutual compression between the multiple rods 132 facilitates the sliding of some rods 132 to the back of the sliding housing 12, thus partially sliding the support assembly 13 to the back of the sliding housing 12.

[0120] In the case where the guide groove 123 is located on the sliding frame 121, the connecting block 133 is fixed to the side wall of the rod 132. At this time, the limiting part 134 can extend from one side of the connecting block 133 along the length direction of the rod 132, that is, the connecting block 133 and the limiting part 134 can form an approximately L-shaped structure, and the cross section of the corresponding guide groove 123 is L-shaped, thereby realizing the limiting part 134 within the guide groove 123; or the limiting part 134 can extend from both sides of the connecting block 133 along the length direction of the rod 132, that is, as shown in Figures 8 and 9, the connecting block 133 and the limiting part 134 can form an approximately inverted T-shaped structure, and the cross section of the corresponding guide groove 123 is inverted T-shaped, thereby realizing the limiting part 134 within the guide groove 123.

[0121] In the case where the guide groove 123 is located on the inner wall of the sliding frame 122, the connecting block 133 is fixed to the end face of the rod 132, and the limiting part 134 is fixed to the side of the connecting block 133 away from the rod 132. At this time, the connecting block 133 and the limiting part 134 can form a straight structure, an L-shaped structure, or a T-shaped structure, etc. The cross-section of the guide groove 123 is a straight structure, an L-shaped structure, or a T-shaped structure, etc., thereby realizing the limiting part 134 within the guide groove 123; or as shown in Figures 8 and 10, the end of the rod 132 extends out of the sliding frame 121, the connecting block 133 is fixed to the side wall of the extension of the rod 132 extending out of the sliding frame 121, and the limiting part 134 extends out of the connecting block 133 in a direction away from the sliding frame 121. At this time, the connecting block 133 and the limiting part 134 can form an L-shaped structure, and the cross-section of the guide groove 123 is L-shaped, thereby realizing the limiting part 134 within the guide groove 123.

[0122] Optionally, the rod 132 has at least a fixed plane facing away from the sliding frame 121. For example, the cross-section of the rod 132 can be rectangular, thereby facilitating the fixed connection (e.g., bonding) between the sliding area of ​​the flexible display screen 2 and the rod 132. The limiting part 134 can be a cylindrical structure to reduce the resistance when the limiting part 134 slides in the guide groove 123, while facilitating the sliding of the limiting part 134 in the bend of the guide groove 123.

[0123] In some embodiments, the sliding mechanism further includes a tensioning member fixed to the back of the fixed housing 11 and fixedly connected to the support assembly 13.

[0124] The tensioning member is fixedly connected to the support assembly 13 on the back of the fixed housing 11, meaning that the supporting portion of the support assembly 13 is always located on the back of the sliding housing 12. Thus, the fixed connection between the tensioning member and the support assembly 13 ensures that when the sliding housing 12 slides closer to the fixed housing 11, the tensioning effect of the tensioning member on the support assembly 13 allows the portion of the support assembly 13 away from the fixed housing 11 to slide more smoothly onto the back of the sliding housing 12.

[0125] Optionally, the tensioning element is an elastic tensioning rope. When the support component 13 slides around to the front of the sliding housing 12, the support component 13 causes the elastic tensioning rope to extend. When the part of the support component 13 away from the fixed housing 11 slides around to the back of the sliding housing 12, the elastic tensioning rope can drive the support component 13 to slide around to the back of the sliding housing 12 better under the action of its own elastic force.

[0126] Optionally, the tensioning component includes a spring and a tensioning cord. The inner end of the spring (i.e., the end located at the winding center) is fixed to the back of the fixed housing 11, and the outer end of the spring (i.e., the end located at the outer winding ring) is fixedly connected to the tensioning cord. The other end of the tensioning cord is fixedly connected to the support assembly 13. Thus, when the support assembly 13 slides to the front of the sliding housing 12, the support assembly 13 drives the spring to tighten via the tensioning cord. When the part of the support assembly 13 away from the fixed housing 11 slides to the back of the sliding housing 12, the spring, under its own elastic force, can drive the support assembly 13 to slide better towards the back of the sliding housing 12 via the tensioning cord.

[0127] It should be noted that the tensioning component can be either of the two types of structures described above, or it can be other tensioning structures, such as a winding motor and a tensioning rope. This disclosure does not limit the specific type of tensioning component.

[0128] This disclosure also provides a display device 10, as shown in FIG11. The display device 10 includes a flexible display screen 2 and a display housing 1 as described in the above embodiments.

[0129] The flexible display screen 2 has a fixed area and sliding areas located on both sides of the fixed area in the first direction X. The fixed area is fixedly connected to the front of the fixed housing 11, and the two sliding areas are respectively fixedly connected to two support components 13. In this way, by sliding at least one of the two sliding housings 12 relative to the fixed housing 11, at least one of the two support components 13 can be driven to slide around to the front or back of the sliding housing 12, thereby adjusting the displayable area on the flexible display screen 2. This improves the user's entertainment experience while ensuring safe driving, and thus increases user engagement.

[0130] Optionally, in conjunction with the fixed housing 11 described above, the edge of the flexible display screen 2 can extend into the groove on the inner side of the fixed frame 112 to ensure the aesthetics of the display device 10; at the same time, the flexible display screen 2 can fit against the inner side of the sliding frame 122 included in the sliding housing 12 to ensure the aesthetics of the display device 10. Meanwhile, the fixed frame 112 and the sliding frame 122 can protect the edge of the flexible display screen 2 to prevent the edge of the flexible display screen 2 from being bumped or hit by external objects.

[0131] In some embodiments, as shown in Figures 12 and 13, the display device 10 further includes a display system 3, which includes a circuit board 31, a display board 32, and a flexible circuit 33. The circuit board 31 is fixed to the back of the fixed housing 11, the display board 32 is located on the side near the back of the fixed housing 11 and is fixed on a sliding housing 12 or a support assembly 13, and the display board 32 is electrically connected to the flexible display screen 2. The flexible circuit 33 is electrically connected to the circuit board 31 and the display board 32 respectively.

[0132] Thus, the display of the image on the flexible display screen 2 can be realized through the electrical connection of the circuit main board 31, the flexible circuit 33, the display main board 32 and the flexible display screen 2. The circuit main board 31 and the display main board 32 are connected through the flexible circuit 33. The flexible circuit 33 is provided with redundancy to ensure that when the support component 13 slides to the front of the sliding housing 12, the display main board 32 can move away from the circuit main board 31.

[0133] In some other embodiments, as shown in FIG11, the flexible display screen 2 includes two splicing screens 21. Each splicing screen 21 includes a fixed area and a sliding area. The fixed areas of the two splicing screens 21 are fixedly connected to the front of the fixed housing 11, and the sliding areas of the two splicing screens 21 are respectively fixedly connected to two support components 13.

[0134] Accordingly, as shown in Figures 12 and 13, the display device 10 also includes two sets of display systems 3, which correspond one-to-one with the two sets of sliding mechanisms. Each set of display systems 3 includes a circuit main board 31, a display main board 32, and a flexible circuit 33. The circuit main board 31 is fixed on the back of the fixed housing 11, and the display main board 32 is located on the side close to the back of the fixed housing 11 and is fixed on the corresponding sliding housing 12 or support component 13, and is electrically connected to the splicing screen 21 fixed on the corresponding support component 13. The flexible circuit 33 is electrically connected to the circuit main board 31 and the display main board 32 respectively.

[0135] Thus, by setting up two sets of display systems 3, the two splicing screens 21 can be controlled independently, that is, the two splicing screens 21 can be displayed independently, improving the operability and entertainment; the two splicing screens 21 can also be displayed synchronously, improving the operability and entertainment through the large display area. In addition, the circuit main board 31 and the display main board 32 of each set of display systems 3 are connected by a flexible circuit 33. The flexible circuit 33 is provided with redundancy to ensure that when the two support components 13 slide around to the front of the sliding housing 12, the two display main boards 32 can move away from the circuit main board 31.

[0136] In both embodiments described above, the circuit board 31 has heat dissipation fins on its surface away from the fixed housing 11, thereby effectively ensuring the heat dissipation of the circuit board 31. Alternatively, the circuit board 31 can be directly fixed to the back of the fixed housing 11 (fixed frame 111), or a groove can be provided on the back of the fixed housing 11 (fixed frame 111) to fix the circuit board 31 within the groove, thus reducing the overall thickness of the display device 10 in the area where the circuit board 31 is fixed. When the display board 32 is fixed to the support assembly 13, the display board 32 is directly bonded to the flexible display screen 2. When the display board 32 is fixed to the sliding housing 12, the display board 32 and the flexible display screen 2 are also electrically connected through a flexible circuit with redundancy. Furthermore, a covering film can be provided at the connection points between the display board 32 and the flexible display screen 2, and at the connections between the flexible circuit 33 and the circuit board 31 and the display board 32, respectively, to ensure the stability of the electrical connection.

[0137] In some embodiments, as shown in FIG13, the display system 3 further includes a fixing plate 34, which is fixedly connected to the fixing housing 11 and pressed onto the circuit board 31. In this way, the fixing plate 34 improves the stability of the circuit board 31 fixed on the fixing housing 11.

[0138] The shape of the fixing plate 34 can be set according to the shape of the blank area (excluding the area of ​​electrical components) on the circuit board. For example, the fixing plate 34 is set as a strip structure to be pressed against one edge of the circuit board 31; or the fixing plate 34 is set as a U-shaped structure to be pressed against the three adjacent edges of the circuit board 31.

[0139] In some embodiments, as shown in Figure 12 or Figure 13, the display system 3 further includes a central control adapter board 35, and the first drive system 14 further includes a motor drive board 36. The central control adapter board 35 is electrically connected to the main circuit board 31 and the motor drive board 36 of the first drive system 14, and is used for electrical connection to an external power supply. The motor drive board 36 is electrically connected to the first drive motor 141. Thus, by setting the central control adapter board 35, an external power supply can be electrically connected to the main circuit board 31 and the motor drive board 36, thereby driving the first drive motor 141 and displaying the image on the flexible display screen 2.

[0140] In the case where the first drive motor 141 described above includes two sub-motors, the first drive system 14 includes two motor drive boards 36. Both motor drive boards are electrically connected to the central control adapter board 35 and are respectively electrically connected to the two sub-motors to realize the driving of the two sub-motors.

[0141] In the case where the display device 10 described above includes two display systems 3, both circuit main boards 31 are electrically connected to the central control adapter board 35 to realize the display of images on the two splicing screens 21.

[0142] Optionally, in conjunction with the above, if a mounting bracket 16 is provided on the back of the fixed housing 11, as shown in Figure 13, the motor drive board 36 can be erected on the back of the fixed housing 11 and fixed on the mounting bracket 16 to save installation space on the back of the fixed housing 11; the central control adapter board 35 is fixed on the mounting bracket 16 and located on the side of the first drive motor 141 away from the fixed housing 11 to save installation space on the back of the fixed housing 11, and at the same time facilitates the connection wiring between the central control adapter board 35 and the external power supply.

[0143] This disclosure also provides an in-vehicle display 100, which includes the display device 10 described in the above embodiments.

[0144] In some embodiments, as shown in FIG14 or FIG15, the vehicle display 100 includes a fixed base 20, a second drive system 40, and a fixed bracket 30; the fixed bracket 30 is slidably limited on the fixed base 20, the second drive system 40 includes a second drive motor 41 and a second drive assembly 42, the second drive motor 41 is fixed on the fixed base 20, and the second drive assembly 42 is connected to the second drive motor 41 and the fixed bracket 30 respectively, and the second drive assembly 42 is used to drive the fixed bracket 30 to move under the drive of the second drive motor 41.

[0145] Thus, through the setting of the second drive system 40 and the slidable connection of the fixed bracket 30 on the fixed base 20, the fixed bracket 30 can drive the display device 10 to move, thereby facilitating the adjustment of the position of the display device 10, so as to further ensure the safe driving of the driver's seat and the operable entertainment of the passenger seat.

[0146] The specific structure of the second drive assembly 42 can be referenced from the structure of the first drive assembly 142 described in the above embodiment. For example, as shown in FIG16, the second drive assembly 42 includes a transmission screw 143, a fixed screw block 144, and a support frame 145. One end of the transmission screw 143 is fixedly connected to the output shaft of the second drive motor 41, and the other end of the transmission screw 143 is rotatably limited on the support frame 145. The fixed screw block 144 is fixed on the fixed bracket 30 and screwed onto the transmission screw 143. Thus, the second drive motor 41 can drive the transmission screw 143 to rotate, thereby enabling the fixed screw block 144 to drive the fixed bracket 30 to move along the transmission screw 143.

[0147] Optionally, as shown in Figure 16, the second drive assembly 42 further includes a limiting rod 146, which is arranged parallel to the transmission screw 143. The limiting rod 146 passes through the fixed screw block 144 and is fixed to the fixed base 20. In this way, the limiting rod 146 can prevent the fixed screw block 144 and the transmission screw 143 from rotating synchronously.

[0148] The sliding connection between the fixed bracket 30 and the fixed base 20 can be similar to the sliding connection between the sliding housing 12 and the fixed housing 11 described above. For example, as shown in Figure 14 or Figure 15, the vehicle display 100 further includes a second guide mechanism 50, which includes a second slide rail 51 and a second slider 52. The second slide rail 51 is fixed to the fixed base 20, and the second slider 52 is fixedly connected to the fixed bracket 30 and slidably limited on the second slide rail 51. Thus, the sliding connection between the fixed bracket 30 and the fixed base 20 can be achieved by the sliding limitation of the second slider 52 on the second slide rail 51.

[0149] In addition, the vehicle display 100 includes a single second guide mechanism 50 or multiple second guide mechanisms 50 arranged side by side. Multiple second guide mechanisms 50 facilitate the stability of the fixed bracket 30. Each second guide mechanism 50 includes a single or multiple second sliders 52. Through multiple second slide rails 51 and multiple second sliders 52 corresponding to each second slide rail 51, multi-point support for the fixed bracket 30 can be achieved to further ensure the stability of the fixed bracket 30, thereby ensuring the stability of the display device 10.

[0150] For example, as shown in Figure 15, the vehicle display 100 includes two second guide mechanisms 50 displayed side by side. Each second guide mechanism 50 includes a second slide rail 51 and two second sliders 52 that are slidably limited on the second slide rail 51. This enables the four second sliders 52 to support the fixed bracket 30, thereby effectively ensuring the stability of the fixed bracket 30 and thus ensuring the stability of the display device 10.

[0151] It should be noted that the sliding direction of the sliding housing 12 relative to the fixed housing 11, and the sliding direction of the fixed bracket 30 relative to the fixed base 20, are respectively taken as examples of the length direction of the first slide rail 151 and the length direction of the second slide rail 51. The length direction of the first slide rail 151 and the length direction of the second slide rail 51 can be parallel to each other, or perpendicular to each other, or of course, other included angles (such as acute angles or obtuse angles).

[0152] Assuming the length of the first slide rail 151 is horizontal, when the length of the first slide rail 151 is perpendicular to the length of the second slide rail 51, the height of the display device 10 can be adjusted along the length of the second slide rail 51 to ensure a wider field of vision for the driver's seat, thereby further ensuring driving safety. When the length of the first slide rail 151 is parallel to the length of the second slide rail 51, the display device 10 can be positioned closer to the driver's seat or closer to the passenger's seat, thereby enabling switching between multiple driving states and further improving operability and entertainment. When the display device 10 is positioned closer to the driver's seat, under the synchronous drive of the first drive system 14 and the second drive system 40, the side of the display device 10 closest to the driver's seat can be kept relatively stationary, thereby further ensuring driving safety.

[0153] In some embodiments, as shown in Figures 17 and 18, the vehicle display 100 further includes a decorative shell 60; the decorative shell 60 includes an inner shell 61 and an outer shell 62, the inner shell 61 and the outer shell 62 are fixedly connected, the bottom of the inner shell 61 and the bottom of the outer shell 62 form a receiving cavity 63, and the bottom of the inner shell 61 has a mounting hole 64 communicating with the receiving cavity 63; the fixed base 20 (not shown in the figure), the fixed bracket 30, and the second drive system 40 (not shown in the figure) are all located in the receiving cavity 63, and the display device 10 is fixedly connected to the fixed bracket 30 at the mounting hole 64.

[0154] The area on the fixed bracket 30 that is fixed to the display device 10 is exposed at the mounting hole 64 to ensure a fixed connection between the display device 10 (e.g., the mounting bracket) and the display device 10.
