[0054] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the drawings.

[0055] The display device provided by the embodiments of the present application can be applied to a vehicle capable of displaying information. Under different use requirements, the user can fold or unfold the display device to meet different requirements. For example, when the user needs to use it, the device can be stretched out and unfolded from the shell; when it is not needed, it can be folded and stored in the shell, thereby releasing the space in the vehicle. In actual application, the types of vehicles capable of displaying information are various, such as cars, ships, trains, etc. The following embodiments will take a car as an example to describe the structure of the display device in the car in detail.

[0056] Please refer to FIG. 1, FIG. 2 and FIG. 3, FIG. 1 is an unfolded effect diagram of a display component of a display device provided by the embodiments of the present application, FIG. 2 is a storage effect diagram of a display component of a display device provided by the embodiments of the present application, and FIG. 3 is a sectional view of FIG. 1. The display device 000 can include a shell 100, a first driving assembly 200, a rotating assembly 300 and a display component 400.

[0057] The shell 100 in the display device 000 can have a containing space C and an opening K in communication with the containing space C.

[0058] The first driving assembly 200 and the rotating assembly 300 in the display device 000 can be located in the containing space C.

[0059] The display component 400 in the display device 000 can include a folding display screen 401 and a folding shell 402 connected with the folding display screen 401. The side of the folding shell 402 away from the folding display screen 401 is connected with the first driving assembly 200 and the rotating assembly 300. In this way, the first driving assembly 200 can drive the folding shell 402 to move, and since the folding shell 402 is connected with the rotating assembly 300, the rotating assembly 300 will also move during the movement of the folding shell 402 driven by the first driving assembly 200.

[0060] In the present application, the first driving assembly 200 in the display device 000 is configured to drive the rotating assembly 300 to move in the direction towards the opening K, so that the rotating assembly 300 can drive the display component 400 to unfold after the display component 400 is stretched out to the outside of the containing space C through the opening K; or drive the rotating assembly 300 to move in the direction away from the opening K, so that the rotating assembly 300 can drive the display component 400 to fold and then let the display component 400 stretch into the containing space C through the opening K.

[0061] In one implementation, when the user needs to use the display function of the display component 400, the folding shell 402 can be driven to move by the first driving assembly 200, so as to drive the rotating assembly 300 to move in the direction towards the opening K, and after the display component 400 is extended out of the accommodating space C through the opening K, the display component 400 is unfolded.

[0062] In another implementation, when the display component 400 needs to be stored to release the space in the car, the folding shell 402 can be driven to move by the first driving assembly 200, so as to drive the rotating assembly 300 to move in the direction away from the opening K, and after the display component 400 is folded, the rotating assembly 300 drives the display component 400 to extend into the accommodating space C through the opening K.

[0063] Therefore, whether the display component 400 needs to be unfolded or stored, the folding shell 402 can be driven to move by the first driving assembly 200, so as to drive the rotating assembly 300 to move in the direction towards the opening K to unfold the display component 400, or to move in the direction away from the opening K to fold the display component 400 and extend into the accommodating space C through the opening K. In this way, when the display device is not used, it can be folded and stored in the accommodating space C in the shell, which greatly saves the space and improves the space utilization rate of the car interior.

[0064] In summary, the display device provided in the application includes a shell, a first driving assembly, a rotating assembly and a display component. Whether the display component needs to be unfolded or stored, the folding shell can be driven to move by the first driving assembly, so as to drive the rotating assembly to move in the direction towards the opening to unfold the display component, or to move in the direction away from the opening to fold the display component and extend into the accommodating space through the opening. In this way, when the display device is not used, it can be folded and stored in the accommodating space C in the shell, which greatly saves the space and improves the space utilization rate of the car interior.

[0065] In the embodiment of the application, please refer to FIG. 4, which is a sectional view of FIG. 2. The folding shell 402 in the display component 400 can include two sub-shells 4021 and a hinge 4022 between the two sub-shells 4021, and the hinge 4022 is connected with the two sub-shells 4021 respectively.

[0066] The first driving assembly 200 in the display device 000 is connected with the side of the hinge 4022 away from the folding display screen 401.

[0067] The number of the rotating assembly 300 in the display device 000 is at least one, and the at least one rotating assembly 300 is connected with the at least one sub-shell 4021.

[0068] In this case, by designing two sub-housings 4021 and the hinge 4022 between them, and connecting the first driving assembly 200 to the side of the hinge 4022 away from the folding display screen 401, the driving force of the first driving assembly 200 can directly act on the hinge 4022, so as not to affect the unfolding and storage of the folding housing 402, thereby effectively improving the driving efficiency.

[0069] Optionally, please refer to FIG. 5, which is another cross-sectional view of FIG. 2. The rotating assembly 300 in the display device 000 can include a rotating part 301 and a first guiding part 302. One end of the rotating part 301 in the rotating assembly 300 is fixedly connected to the side of the sub-housing 4021 away from the folding display screen 401, and the other end of the rotating part 301 is movably connected to the first guiding part 302. The first guiding part 302 is fixed in the accommodating space C.

[0070] In the present application, during the process that at least part of the display component 400 is located in the accommodating space C and is driven to move by the first driving assembly 200, the rotating part 301 slides relative to the first guiding part 302, and the sliding direction of the rotating part 301 relative to the first guiding part 302 is the same as the moving direction of the display component 400; during the process that the display component 400 is entirely extended out of the accommodating space C through the opening K and is driven to move by the first driving assembly 200, the rotating part 301 rotates relative to the first guiding part 302 to drive the display component 400 to unfold or fold.

[0071] In this case, by movably connecting the rotating part 301 and the first guiding part 302, the rotating part 301 can slide and rotate relative to the first guiding part 302 under the driving of the first driving assembly 200, so as to more accurately control the movement and form change of the display component 400.

[0072] In the embodiment of the present application, please refer to FIG. 6, which is a schematic view of the display component in the unfolded state and the rotating assembly and the display component in the folded state and the rotating assembly, respectively. The rotating part 301 in the rotating assembly 300 has a sliding protrusion 3011 at the end away from the display component 400, and the first guiding part 302 has a guiding sliding groove 3021 matched with the sliding protrusion 3011.

[0073] At least part of the sliding protrusion 3011 is located in the guide sliding groove 3021 and is in sliding connection with the guide sliding groove 3021. In this way, through the matching design of the sliding protrusion 3011 and the guide sliding groove 3021, stable support and clear guide path are provided for the sliding of the rotating part 301 relative to the first guide part 302, so as to effectively prevent deviation and shaking during the sliding process, and the stability of the movement of the display part 400 is ensured.

[0074] Optionally, please refer to FIG. 7, which is a schematic diagram of another display part in an unfolded state and a folded state and a rotating assembly according to an embodiment of the present application. It should be noted that, in order to facilitate observation, both FIG. 6 and FIG. 7 show two states of the display part 400 on the same figure. The guide sliding groove 3021 in the first guide part 302 can include a first sliding groove 30211 and a second sliding groove 30212 in communication with the first sliding groove 30211. The extension direction of the first sliding groove 30211 is parallel to the direction in which the first driving assembly 200 drives the display part 400 to move, and the second sliding groove 30212 is an arc-shaped sliding groove, and the second sliding groove 30212 is closer to the opening K relative to the first sliding groove 30211.

[0075] In this case, under the driving of the first driving assembly 200, when the rotating assembly 300 moves to the connection position of the first sliding groove 30211 and the second sliding groove 30212, since the second sliding groove 30212 is designed as an arc-shaped sliding groove, the rotating assembly 300 will be subjected to a guiding overturning force during the continuous sliding process. This overturning force will cause the rotating assembly 300 and the sub-housing 4021 connected thereto to overturn along the path of the arc-shaped sliding groove 30212, thereby achieving the unfolding or folding of the display part 400.

[0076] For example, the center of the arc-shaped sliding groove is located on the side away from the opening K. In this way, when the arc-shaped sliding groove 30212 provides the overturning force, it can make the two sub-housings 4021 overturn in opposite directions, so that the display part 400 can be smoothly unfolded and folded.

[0077] Optionally, as shown in FIG. 7, the hinge 4022 in the folding housing 402 has a protruding part 40221 on the side away from the folding display screen 401, the protruding part 40221 is connected with the first driving assembly 200, and the setting position of the protruding part 40221 on the hinge 4022 is arranged adjacent to the connection position of the rotating part 301 on the sub-housing 4021.

[0078] The rotating part 301 in the rotating assembly 300 has an avoiding groove Q, and at least part of the protruding part 40221 is located in the avoiding groove Q after the display component 400 is in the unfolded state; all of the protruding part 40221 is located outside the avoiding groove Q after the display component 400 is in the folded state.

[0079] In this case, during the unfolding of the display component 400, the protruding part 40221 can gradually enter the avoiding groove Q, so as to avoid the mutual interference between the protruding part 40221 and the rotating part 301, and ensure the smoothness of folding.

[0080] In the embodiment of the present application, please refer to FIG. 8 and FIG. 9, FIG. 8 is a schematic diagram of the connection between the display component and the rotating assembly provided in the embodiment of the present application, and FIG. 9 is an exploded view of FIG. 8. The two sub-housings 4021 in the folding housing 402 have a notch away from the side of the folding display screen 401. Among them, the two notches are respectively a first notch M1 and a second notch M2, and the first notch M1 and the second notch M2 are both distributed close to the protruding part 40221.

[0081] In the present application, after the display component 400 in the display device 000 is in the unfolded state, the first notch M1 and the second notch M2 are used to enclose an avoiding space N, and at least part of the protruding part 40221 is located in the avoiding space N. In this way, the interference between the protruding part 40221 and other components can be reduced, and the obstruction during the unfolding and folding of the display component 400 is reduced, so that the use experience is more smooth.

[0082] In the present application, since the number of the rotating assembly 300 is at least one, and at least one rotating assembly 300 is connected with at least one sub-housing 4021. In order to clarify, the embodiment of the present application will be described illustratively by taking the following two optional implementation manners as examples:

[0083] In the first optional implementation manner, in the case that the number of the rotating assembly 300 in the display device 000 is one, the end of the rotating part 301 away from the first guide part 302 is fixedly connected with the corresponding sub-housing 4021 at the first notch M1; wherein, after the display component 400 is in the unfolded state, the end of the rotating part 301 away from the first guide part 302 abuts against the corresponding sub-housing 4021 at the second notch M2.

[0084] In the embodiment of the present application, the hinge 4022 in the folding housing 402 has a synchronous mechanism (not shown), and the synchronous mechanism is configured to drive another sub-housing 4021 to synchronously rotate in the opposite direction during the rotation of the rotating part 301 driving the connected sub-housing 4021.

[0085] It should be noted that the synchronous connection here can refer to: the movement of one part can drive the synchronous movement of another part. To this end, during the folding or unfolding of the display part 400, when the sub-housing 4021 on one side of the hinge 4022 rotates, the sub-housing 4021 on the other side of the hinge 4022 can rotate synchronously through the synchronous assembly. In this way, the synchronous assembly can realize the synchronous rotation of the two sub-housings 4021 towards each other and the synchronous rotation away from each other.

[0086] In this case, after the display device 000 is unfolded under the action of the rotating assembly 300, the rotating part 301 can support the corresponding sub-housing 4021 at the second gap M2, so that the sub-housing 4021 at the second gap M2 is also effectively reinforced, thereby improving the stability of the entire display device 000.

[0087] The second optional implementation manner is shown in FIGS. 8 and 9. In the case where the number of rotating assemblies 300 in the display device 000 is two, in one rotating assembly 300, the end of the rotating part 301 away from the first guide part 302 is fixedly connected with the corresponding sub-housing 4021 at the first gap M1; in the other rotating assembly 300, the end of the rotating part 301 away from the first guide part 302 is fixedly connected with the corresponding sub-housing 4021 at the second gap M2; wherein, after the display part 400 is in the unfolded state, the two rotating parts 301 abut against each other, and the two relief grooves Q in the two rotating parts 301 can enclose a relief cavity H for accommodating the protruding part 40221.

[0088] In this case, by designing the two relief grooves Q in the two rotating parts 301, the two relief grooves Q can enclose the relief cavity H for accommodating the protruding part 40221 after the display part 400 is unfolded, so as to avoid the interference between the two rotating parts 301 and the protruding part 40221, thereby making the structure of the display device 000 more compact.

[0089] It should be noted that since the number of rotating assemblies 300 in the display device 000 is two, and the two rotating assemblies 300 can respectively drive the connected sub-housings 4021 to rotate, in this case, the hinge 4022 in the folding housing 402 can be provided with a synchronous assembly, or can not be provided with a synchronous assembly.

[0090] As shown in FIG. 10, which is a schematic diagram of the connection between the display component and the rotating assembly according to another embodiment of the present application. In the case where the number of rotating assemblies 300 in the display device 000 is two, after the display component 400 is in the folded state and located in the accommodating space C, the display component 400 is distributed between the two first guide portions 302 of the two rotating assemblies 300. In this way, by reasonably arranging the position of the display component 400, the accommodating space C can be effectively utilized, thereby saving space.

[0091] In the embodiment of the present application, please refer to FIG. 11, which is another cross-sectional view of FIG. 1. The first driving assembly 200 in the display device 000 can include a first driving motor 201, a lead screw 202 and an adapter 203.

[0092] The first driving motor 201 in the first driving assembly 200 is connected with the lead screw 202, and a part of the adapter 203 is sleeved on the lead screw 202 and is in sliding connection with the lead screw 202, and another part of the adapter 203 is fixedly connected with the protruding portion 40221.

[0093] In the present application, the adapter 203 can include a nut 2031 sleeved on the lead screw 202, an adapter fixing portion 2032 and a connecting rod 2033. One end of the connecting rod 2033 is fixedly connected with the protruding portion 40221, and the other end of the connecting rod 2033 is connected with the adapter fixing portion 2032.

[0094] When the first driving motor 201 is started, the output shaft of the first driving motor 201 drives the lead screw 202 to rotate. The rotation of the lead screw 202 causes the nut 2031 sleeved thereon to move linearly along the lead screw 202. The nut 2031 drives the adapter fixing portion 2032 to move, thereby driving the connecting rod 2033 fixedly connected with the adapter fixing portion 2032 to move, and further driving the protruding portion 40221 to move linearly. In this way, the conversion from rotary motion to linear motion can be realized by the first driving assembly 200, and the protruding portion 40221 is driven to move correspondingly.

[0095] Optionally, please refer to FIG. 12 and FIG. 13, which are another cross-sectional view of FIG. 1 and a schematic diagram of the movement of the cover plate according to an embodiment of the present application. The display device 000 can further include a second driving assembly 500 and a cover plate 600.

[0096] The cover plate 600 in the display device 000 is movably connected with the shell 100 at the opening K, and the second driving assembly 500 is located in the accommodating space C and is connected with the cover plate 600.

[0097] The second driving assembly 500 in the display device 000 is configured to drive the cover plate 600 to move towards the opening K after the display component 400 is located in the accommodation space C, so that the cover plate 600 covers the opening K; or drive the cover plate 600 to move away from the opening K before the display component 400 extends through the opening K, so that the cover plate 600 is separated from the opening K.
