Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and in particular to a rollable flexible display device and terminal equipment. Background Technology

[0002] Automotive display technology is rapidly evolving, with technologies such as traditional LCD (Liquid Crystal Display, a display screen that uses the optical properties of liquid crystal materials to control the light transmittance by manipulating an electric field to display images) quickly upgrading to OLED (Organic Light Emitting Diode) and MINILED (Miniature Light Emitting Diode). The application of these display technologies will change the way traditional displays and interactions are conducted, providing superior display effects and a more precise human-computer interaction experience.

[0003] Currently, various innovative display technologies have emerged in the market, such as privacy screens, transparent displays, foldable or rollable flexible displays, height-adjustable or sliding displays, and light field screens. The application of these technologies has allowed in-vehicle displays to move beyond traditional locations and shapes such as the center console and instrument panel, and instead develop in a more diversified direction.

[0004] In the prior art, traditional flexible display devices include at least a display screen made of flexible screen. When a traditional flexible display device is installed on a terminal device (e.g., a car), the display screen made of flexible screen will occupy a lot of interior space, regardless of whether the user uses the display function of the traditional flexible display device. Therefore, in order to reduce the space occupied by the display screen made of flexible screen, manufacturers usually reduce the display area of ​​the display screen made of flexible screen, which makes it difficult for traditional flexible display devices to have a significant sense of technology.

[0005] In summary, traditional flexible display devices have either a small display area or a large space requirement, making it difficult to balance space saving with achieving a larger display area, thus reducing the user experience of traditional flexible display devices. Utility Model Content

[0059] Please see Figures 1-8 The rollable flexible display device 100 includes: a retractable assembly 1 and a display screen 2.

[0060] The display screen 2 is made of a rollable flexible screen; a rollable flexible screen refers to a screen that can be bent, rolled or even folded while ensuring good display function.

[0061] In addition, the take-up and take-down assembly 1 includes at least a housing component 11, a roller 12, a drive component 13, a transmission component 14, and a guide component 15.

[0062] Furthermore, at least a portion of the roller 12, drive component 13, and transmission component 14 are housed inside the housing component 11, and the guide component 15 is located outside the housing component 11.

[0063] Specifically, at least a portion of the transmission component 14 is movably connected to the guide component 15, and the drive component 13 can drive at least a portion of the transmission component 14 to move under the guidance of the guide component 15 in a preset manner.

[0064] It should be noted that the above-mentioned "preset situation" can be understood as follows: when the driving component 13 drives at least a part of the transmission component 14 to move under the guidance of the guide component 15, the movement needs to be preset according to the installation requirements of the rollable flexible display device 100 and the terminal device or according to the retraction position of the display screen 2; for example, "moving in a preset situation" in the embodiments of this application can be understood as moving along the first direction 1001 (the first direction 1001 is the extension direction of the slide rail 151 or the length direction of the slide rail 151).

[0065] In this embodiment of the application, one end of the display screen 2 is connected to the roller 12, and the other end is provided with a top plate 203; at least a portion of the top plate 203 can be connected to a portion of the transmission component 14 so that at least a portion of the display screen 2 can follow the movement of the transmission component 14 to unfold outward toward the housing component 11 and roll inward toward the housing component 11.

[0066] In some embodiments, such as Figures 1-7 As shown, the drive component 13 is a motor controller module 131 with a drive gear 1311; the transmission component 14 includes a first sliding screw mechanism 141 with a first transmission thread 1410 and a second sliding screw mechanism 142 with a second transmission thread 1420; the guide component 15 includes a pair of slide rails 151.

[0067] Understandably, one end of each slide rail 151 is fixed to the housing component 11, and the other end extends outward from the housing component 11 along the first direction 1001.

[0068] It should be noted that the two opposite ends of the top plate 203 in the second direction 1002 are respectively connected to the first mounting part 1411 of the first sliding screw mechanism 141 and the second mounting part 1421 of the second sliding screw mechanism 142; the first mounting part 1411 and the second mounting part 1421 are arranged opposite to each other in the second direction 1002, and the first mounting part 1411 and the second mounting part 1421 respectively extend into a pair of slide rails 151; the second direction 1002 and the first direction 1001 are orthogonal to each other.

[0069] It is understood that the first transmission thread 1410 and the second transmission thread 1420 are both meshed with the drive gear 1311 on opposite sides in the first direction 1001, so that the first sliding screw mechanism 141 and the second sliding screw mechanism 142 move in opposite directions. At this time, the first mounting part 1411 and the second mounting part 1421 move along the first direction 1001 guided by a pair of slide rails 151, forcing the top plate 203 to drive the display screen 2 to unfold and retract along the first direction 1001.

[0070] In summary, since the first mounting part 1411 and the second mounting part 1421 are arranged opposite each other in the second direction 1002, and the first mounting part 1411 and the second mounting part 1421 extend into a pair of slide rails 151 respectively, the pair of slide rails 151 can be understood as being arranged in the second direction 1002.

[0071] To further explain, the rollable flexible display device 100 uses a motor controller module 131 to drive the first sliding screw mechanism 141 and the second sliding screw mechanism 142 to unfold and roll up the display screen 2, which not only reduces noise, but also allows for more precise control of the unfolding and rolling up speed of the display screen 2.

[0072] Specifically, winding refers to the process of the display screen 2 being wound around the roller 12. This process is usually carried out when the user is not using the display function of the display screen 2 in order to reduce the space occupied by the display screen 2. Unwinding refers to the process of the display screen 2 wound around the roller 12 being moved towards the outside of the housing component 11 along the first direction 1001 under the guidance of a pair of slide rails 151. This process is usually carried out when the user needs to use the display function of the display screen 2 in order to provide a larger display area.

[0073] It should be noted that the motor controller module 131 drives the first sliding screw mechanism 141 and the second sliding screw mechanism 142 to move in a preset manner through the drive gear 1311, and provides power for the unfolding and rewinding of the display screen 2; wherein, the motor controller module 131 can rotate in both directions, that is, the rotation direction of the motor controller module 131 can be changed by changing the direction of the current, thereby realizing the unfolding and rewinding of the display screen 2.

[0074] In this embodiment, the rollable flexible display device 100 changes the rotation direction of the motor controller module 131 by changing the direction of the current, thereby enabling the display screen 2 to unfold and roll up. This flexibility allows the terminal device to switch between portable and large screen according to the user's needs, thereby enhancing the technological feel of the rollable flexible display device 100.

[0075] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 and Figure 8 It is known that the display screen 2 includes a curling part 201 and an unfolding part 202.

[0076] The top plate 203 is disposed on the unfolding part 202; the curling part 201 is wound around the roller 12 and can be hidden inside the housing component 11.

[0077] Additionally, the unfolding section 202 can follow the top plate 203 and move along a first direction 1001 toward the outside or inside of the housing component 11 under the guidance of a pair of slide rails 151, and the unfolding section 202 can be used for display.

[0078] In some embodiments, according to Figures 1-3 It can be seen that the housing component 11 includes: a first housing 111 and a second housing 112.

[0079] Specifically, the first shell 111 and the second shell 112 cover each other to form an enclosing space.

[0080] To further explain, the first housing 111 has a groove 1111 on its surface within the accommodating space, and the groove 1111 is used to place the roller 12 and the curled portion 201 wound around the roller 12.

[0081] In this embodiment, the roller 12 can rotate; the two opposite ends of the roller 12 in the second direction 1002 can be disposed on bearing seats (the bearing seats are embedded in the grooves 1111 at the two opposite ends in the second direction 1002), and then rotate as the unfolding part 202 moves; of course, the roller 12 can also be rotated by connecting an additional drive member.

[0082] When the unfolded part 202 moves toward the inside of the housing component 11 along the first direction 1001, the unfolded part 202 can be wound onto the roller 12 as the roller 12 rotates.

[0083] In addition, when the unfolding part 202 moves toward the outside of the housing component 11 along the first direction 1001, the curling part 201 can unfold (or be released) from the roller 12 following the rotation of the roller 12.

[0084] In some embodiments, by Figure 1 and Figure 4 It is known that the first sliding screw mechanism 141 includes: a first arc-shaped part 1412, a first screw part 1413, and a second arc-shaped part 1414.

[0085] It is understandable that one end of the first arc-shaped portion 1412 and one end of the second arc-shaped portion 1414 are respectively connected to the two opposite ends of the first screw portion 1413 in the second direction 1002.

[0086] It should be noted that the first transmission thread 1410 is provided on the first screw portion 1413; the first mounting portion 1411 is provided at the other end of the first arc-shaped portion 1412.

[0087] In some embodiments, refer to Figure 1 and Figure 4 It is known that the second sliding screw mechanism 142 includes: a third arc-shaped part 1422, a second screw part 1423, and a fourth arc-shaped part 1424.

[0088] In this embodiment of the application, one end of the third arc-shaped portion 1422 and one end of the fourth arc-shaped portion 1424 are respectively connected to the two opposite ends of the second screw portion 1423 in the second direction 1002.

[0089] Specifically, the second transmission thread 1420 is provided on the second screw portion 1423; the second mounting portion 1421 is provided at the other end of the fourth arc-shaped portion 1424.

[0090] In some embodiments, combined with Figure 1 , Figure 6 and Figure 7 It is known that the first arc-shaped portion 1412 and the third arc-shaped portion 1422 are located on the same side, and the second arc-shaped portion 1414 and the fourth arc-shaped portion 1424 are located on the same side, so that the first mounting portion 1411 and the second mounting portion 1421 are arranged opposite to each other in the second direction 1002.

[0091] In some embodiments, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the retractable assembly 1 also includes a pair of sliders 3.

[0092] Each slide rail 151 has a slide groove 1511 and a receiving cavity 1512; the slide groove 1511 and the receiving cavity 1512 are connected, and a part of the first mounting part 1411 and a part of the second mounting part 1421 can extend into the receiving cavity 1512.

[0093] In addition, another part of the first mounting part 1411 and another part of the second mounting part 1421 are both disposed in the slide groove 1511.

[0094] In addition, each slider 3 is embedded in a corresponding groove 1511, and at least a portion of the top plate 203 can pass through the slider 3.

[0095] In some embodiments, please refer to Figures 1-8 The first mounting part 1411 and the second mounting part 1421 have the same structure.

[0096] It should be noted that the first mounting part 1411 or the second mounting part 1421 includes: a fixing block 1401 and a third screw part 1402 having an adjusting thread.

[0097] It is understandable that the fixing block 1401 is fitted onto the third screw section 1402 by adjusting the thread so that the fixing block 1401 can move on the third screw section 1402.

[0098] Specifically, since the fixing block 1401 can move on the third screw part 1402, the user can adjust the relative position of the fixing block 1401 on the third screw part 1402 to avoid the top plate 203 being in a front-to-back state on the first direction 1001 with the two opposite ends on the second direction 1002. Such a state would make it difficult for the two opposite ends of the top plate 203 on the second direction 1002 to follow the movement of the first mounting part 1411 and the second mounting part 1421 to achieve synchronous movement on the first direction 1001. In severe cases, it may even cause the unfolding part 202 to get stuck during unfolding, thereby reducing the user's user experience.

[0099] In this embodiment, the third screw portion 1402 extends into the receiving cavity 1512, and the fixing block 1401 corresponds to the slider 3; at least a portion of the top plate 203 passes through the slider 3 and is connected to the fixing block 1401; or at least a portion of the top plate 203 is fixedly connected to the slider 3, and the slider 3 is connected to the fixing block 1401.

[0100] In some embodiments, such as Figure 1 As shown, the retraction assembly 1 also includes: a first copper tube 4, a second copper tube 5, a third copper tube 6, and a fourth copper tube 7.

[0101] The first copper tube 4 has a shape that is adapted to the first arc-shaped portion 1412 and is sleeved on the first arc-shaped portion 1412; the second copper tube 5 has a shape that is adapted to the second arc-shaped portion 1414 and is sleeved on the second arc-shaped portion 1414.

[0102] In addition, the third copper tube 6 has a shape that is adapted to the third arc-shaped portion 1422, and the third copper tube 6 is sleeved on the third arc-shaped portion 1422; the fourth copper tube 7 has a shape that is adapted to the fourth arc-shaped portion 1424, and the fourth copper tube 7 is sleeved on the fourth arc-shaped portion 1424.

[0103] In this embodiment, the copper tube components, including the first copper tube 4, the second copper tube 5, the third copper tube 6, and the fourth copper tube 7, all have internal receiving cavities (not shown in the figures). These receiving cavities can be filled with a certain amount of grease or lubricant to minimize friction or jamming during movement of the first arc-shaped portion 1412, the second arc-shaped portion 1414, the third arc-shaped portion 1422, and the fourth arc-shaped portion 1424, which are fitted into the receiving cavities. This results in minimal friction or jamming of the first arc-shaped portion 1412, the second arc-shaped portion 1414, the third arc-shaped portion 1422, and the fourth arc-shaped portion 1424 during movement. The three arc-shaped portions 1422 and the fourth arc-shaped portion 1424 operate smoothly.
