[0044] Most car display screens on the market are currently fixed in shape and cannot be stored when not in use, taking up considerable interior space. While existing rollable screens can be rolled up for storage, because they are flexible screens, they lack support at the back when open, making them prone to deformation and wrinkles. This results in poor screen display, and touch can exacerbate screen deformation and dents.

[0045] This utility model proposes a display screen device and vehicle, which aims to improve the rigidity of the screen while enabling it to be rolled up and stored.

[0046] Please see Figure 1-5 In one embodiment of this utility model, the display screen 2 device 100 includes a substrate 1, a display screen 2, and a winding mechanism 3. The substrate 1 has a first side 11 and a second side 12 along its thickness direction, and the second side 12 forms an accommodating area. The display screen 2 includes a fixed section 21 and a winding section 22 connected to each other. The fixed section 21 is disposed on the first side 11, and one end of the winding section 22 is connected to the fixed section 21, while the other end passes around the edge of the substrate 1 and is disposed in the accommodating area. The winding mechanism 3 includes a traction part 31 and a support part 32. The traction part 31 is disposed on the second side 12 and is connected to the winding section 22 so that the winding section 22 can enter or leave the accommodating area. The support part 32 is movably disposed on the second side 12 along the length direction of the substrate 1. The support part 32 has a support surface 321, which can abut against the side of the winding section 22 near the substrate 1.

[0047] The technical solution of this utility model, through the coordinated operation of the traction part 31 and the support part 32 of the winding mechanism 3, enables the flexible storage and unfolding of the display screen 2. When unfolding is required, the traction part 31 is activated, pulling the winding section 22 gradually unfolding from the receiving area. At the same time, the support part 32 moves along the length direction of the substrate 1, so that the winding section 22 remains stable during unfolding, reducing the generation of twisting or wrinkles. The support surface 321 of the support part 32 closely abuts against the side of the winding section 22 near the substrate 1, providing stable support for the winding section 22. This allows the display screen 2 to remain flat in the unfolded state, improving the rigidity of the display screen and thus improving the display effect.

[0048] It is understood that the traction unit 31 can be driven by an electric motor, for example, connected to the take-up section 22 via a gear or belt drive system. When the motor rotates, it can drive the take-up section 22 into or out of the receiving area along a predetermined path; or it can use a spring mechanism, for example, using the force of a spring as a power source, with one end of the spring fixed to the base plate 1 and the other end connected to the take-up section 22. By releasing or tightening the spring, the take-up section 22 can be automatically extended or retracted; or it can use a magnetic traction device, for example, using a suitable material (such as a ferromagnetic material) between the take-up section 22 and the traction unit 31, using an internal or external electromagnet to attract or repel the take-up section 22, thereby controlling its position.

[0049] It is understood that the accommodating area in this application refers to the storage space capable of accommodating the winding section 22.

[0050] It is understood that the specific way in which the support part 32 is movably set can be by using a sliding guide rail system, that is, the support part 32 can be installed on one or more pairs of parallel sliding guide rails, allowing it to move linearly along a predetermined path; or by using a telescopic rod structure, that is, by using a multi-section nested telescopic rod, the length of the support part 32 can be changed, thereby adjusting its position or height.

[0051] In one embodiment, the traction part 31 includes a traction rope 311, one end of which is connected to one end of the winding section 22 disposed in the receiving area, and the other end of which is wound around the support part 32.

[0052] This configuration, through the combination of the traction rope 311 and the support portion 32, enables effective control and support of the winding section 22. Simultaneously, since the traction rope 311 is wound around the support portion 32, the support portion 32 not only provides necessary support force to the winding section 22 during movement but also ensures the stability and flatness of the winding section 22 during unfolding through the tension adjustment of the traction rope 311. This reduces problems such as twisting, wrinkling, or loosening of the winding section 22 during unfolding or retracting.

[0053] In one embodiment, the support portion 32 includes a support frame 322 and a support rod 323; the support frame 322 is movably disposed on the second side 12, and the support surface 321 is provided at one end of the support frame 322 near the winding section 22; the support rod 323 is mounted on the support frame 322 along the width direction of the substrate 1; and the traction portion 31 is wound around the support frame 322.

[0054] With this configuration, the support surface 321 can support and fix the winding section 22. During the unfolding or winding process, the winding section 22 can move smoothly and maintain the correct position. The traction part 31 is wound around the support frame 322, so that the traction part 31 (such as the traction rope 311) can be wound and released along the support frame 322 and the support rod 323, thereby achieving the purpose of stable support and flexible adjustment of the winding section 22 of the display screen 2, improving the stability and reliability of the display screen 2 device 100.

[0055] In one embodiment, the support surface 321 is provided with an arc-shaped transition.

[0056] This design, with its arc-shaped support surface 321, provides a smoother transition, allowing the winding section 22 to move more smoothly during unfolding or winding, thus reducing the possibility of stress concentration and damage to the winding section 22 during unfolding.

[0057] In one embodiment, the winding mechanism 3 further includes a hinge assembly 33, which is disposed between the support portion 32 and the winding section 22. The side of the hinge assembly 33 away from the support portion 32 is connected to the winding section 22, and the two ends of the hinge assembly 33 on the side closer to the support portion 32 are slidably disposed with the support portion 32.

[0058] This configuration, with the hinge assembly 33 connected to the winding section 22 on the side furthest from the support portion 32, allows the winding section 22 to be flexibly unfolded and wound up via the hinge assembly 33. Because the hinge assembly 33 has a certain degree of mobility and rotational freedom, the winding section 22 can unfold more smoothly, reducing deformation or damage caused by direct pulling.

[0059] Specifically, in one embodiment, the hinge assembly 33 further includes a plurality of rotating rods 331; the plurality of rotating rods 331 are sequentially arranged between the support portion 32 and the winding section 22 along the length direction of the substrate 1, and the side of the plurality of rotating rods 331 away from the support portion 32 is connected to the winding section 22, and the two ends of each rotating rod 331 are rolled relative to the support portion 32.

[0060] With this configuration, the winding section 22 can be subjected to force more evenly through the coordinated action of multiple rotating rods 331, reducing the possibility of deformation or damage caused by single-point force. The rolling configuration also allows the rotating rods 331 to better adapt to the unfolding requirements of different angles and directions, improving the flexibility of the display screen 2 device 100.

[0061] In one embodiment, the hinge assembly 33 further includes a hinge group 332 and a plurality of mounting plates 3322. The hinge group 332 includes a plurality of hinges 3321, which are rotatably mounted on the plurality of rotating rods 331 along the length direction of the substrate 1, so as to divide each of the rotating rods 331 into two segments in the width direction of the substrate 1. The plurality of mounting plates 3322 are arranged corresponding to the plurality of rotating rods 331, and one side of each mounting plate 3322 is fixedly connected to the winding section 22, and the other side is fixedly connected to the rotating rod 331.

[0062] With this configuration, when the winding section 22 unfolds or rewinds, the hinge assembly 332 allows the rotating rod 331 to bend and rotate while maintaining overall stability, thereby better adapting to the deformation requirements of the display screen 2.

[0063] It should be added that, such as Figure 4 As shown, the hinge 3321 may have an elongated hole inside it, and the rotating rod 331 is provided with a connecting pin that contacts the inner wall of the elongated hole. In this way, multiple hinges 3321 are connected by the connecting pin, thereby connecting each rotating rod 331. The connecting pin generates displacement in the elongated hole, thereby enabling multiple hinge assemblies 33 to be wound up, thereby winding up the winding section 22.

[0064] In one embodiment, the winding mechanism 3 further includes a driving component 34, which is disposed on the side of the support portion 32 away from the substrate 1, for driving the support portion 32 to move along the length direction of the substrate 1 on the second side 12.

[0065] With this configuration, the driving component 34 can precisely control the moving speed and position of the support 32 along the length of the substrate 1, thereby achieving fine adjustment of the unfolding and winding process of the winding section 22.

[0066] Specifically, in one embodiment, the drive assembly 34 includes a housing 341, a dual-head motor 342, two drive shafts 343, two drive gears 344, two screws 345, two transmission gears 346, and two moving blocks 347. The housing 341 has an installation space. The dual-head motor 342 is disposed in the installation space. The two drive shafts 343 are respectively connected to the two output ends of the dual-head motor 342. The two drive gears 344 are respectively sleeved on the outer peripheral walls of the two drive shafts 343. The two screws 345 are disposed in the installation space and are respectively arranged along the length direction of the base plate 1 corresponding to the two drive shafts 343. The two transmission gears 346 are respectively sleeved on the outer peripheral walls of the two screws 345 and respectively mesh with the two drive gears 344. The two moving blocks 347 are respectively sleeved on the outer peripheral walls of the two screws 345 and pass through the outside of the housing 341, and are connected to the support portion 32.

[0067] With this configuration, the dual-head motor 342 provides rotational power to the transmission shaft 343, thereby driving the drive gear 344 to rotate. The driven gear meshing with it rotates, causing the screw 345 to rotate, which in turn drives the moving block 347 to rise and fall along the length of the base plate 1, thus achieving the purpose of raising and lowering the support part 32.

[0068] This utility model also proposes a vehicle that includes a display screen device. The specific structure of the display screen device is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0069] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
