[0030] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] Please see Figures 1 to 6 The present invention will now describe a liftable display screen structure. A liftable display screen structure includes a housing 100, a cover plate 200, a display screen body 300, a drive mechanism, and a transmission mechanism.

[0032] The top of the housing 100 has an opening; the display screen body 300 can be movably disposed within the housing 100 through the opening under the drive of the driving mechanism, and can be in a hidden state or an extended state; the cover plate 200 is disposed on the housing 100 for closing or opening the opening, and has a pre-set slide on the housing 100, and the cover plate 200 can move along the slide to have an exposed position or a retracted position; the transmission mechanism includes a second connecting rod 450 disposed between the driving mechanism and the cover plate 200, and the cover plate 200 can move along the slide under the drive of the second connecting rod 450.

[0033] This invention provides a liftable display screen structure. Compared with existing technologies, the transmission mechanism drives the second link 450 via the drive mechanism, causing the cover plate 200 to slide along the slide rail to the exposed position. Simultaneously, the drive mechanism drives the display screen body 300 to the hidden state. Alternatively, the transmission mechanism drives the second link 450 in the opposite direction via the drive mechanism, causing the cover plate 200 to slide along the slide rail to the storage position. Simultaneously, the drive mechanism drives the display screen body 300 to the extended state. This liftable display screen structure allows the display screen body 300 to be hidden when the car is closed, and extended when the car is started, via the retracted position of the cover plate 200. This adds a sense of ceremony to the driving experience and avoids the display screen being constantly exposed, reducing the probability of wear and tear.

[0034] The driving mechanism includes a drive gear 410 and a driven gear 420 rotatably disposed within the housing 100, a first connecting rod 440, and a drive motor 430 disposed on the housing 100 for driving the drive gear 410 to rotate. The drive gear 410 and the driven gear 420 are laterally disposed below the display screen body 300 and mesh with each other. The two first connecting rods 440 are respectively fixed to the drive gear 410 or the driven gear 420, and are used to simultaneously drive the display screen body 300 to rise or fall. The two second connecting rods 450 are respectively hinged to the drive gear 410 or the driven gear 420, and are used to drive the two cover plates 200 laterally closer to each other or further away from each other.

[0035] Specifically, the drive motor 430 in the drive mechanism drives the drive gear 410 to rotate, thereby causing the drive gear 410 and the driven gear 420 meshing with it to rotate simultaneously. The lower ends of the two first connecting rods 440 are eccentrically rotatably connected to the drive gear 410 and the driven gear 420, respectively, and the upper ends of the two first connecting rods 440 are rotatably connected to the lower part of the display screen body 300. The two first connecting rods 440 drive the display screen body 300 to rise and fall with the rotation of the drive gear 410 and the driven gear 420. One end of the second link 450 is hinged to the rotating shaft of the driving gear 410 or the driven gear 420, and the other end of the second link 450 is rotatably connected to one end of the cover plate 200. One end of the second link 450 rotates synchronously with the driving gear 410 or the driven gear 420, thereby causing the cover plate 200 connected to the other end of the second link 450 to slide along the slide rail, so that the cover plate 200 closes the opening of the housing 100 to achieve the exposed position or opens the opening of the housing 100 to achieve the storage position. At the same time, the display screen body 300 is closed inside the housing 100 to achieve the hidden position or exposed from the opening of the housing 100 to achieve the extended state.

[0036] The first link 440 can be a single link or a link group consisting of multiple links that extend and retract along a predetermined path. The first link 440 is fixedly connected to the driving gear 410 and the driven gear 420. As the driving gear 410 and the driven gear 420 rotate, the link 440 can maintain its axial position relative to the driving gear 410 and the driven gear 420. The second link 450 is fixedly connected to the rotation shaft of the driving gear 410 or the driven gear 420.

[0037] Optional, please refer to Figure 6 The slide rails include a transverse slide rail 110 and a longitudinal slide rail 120. The transverse slide rail 110 is located on the upper part of the housing 100 and extends along the length of the opening. The longitudinal slide rail 120 is located on one side of the housing 100 and communicates with the transverse slide rail 110. The cover plate 200 slides to the transverse slide rail 110 to reach a retracted position, and slides to the longitudinal slide rail 120 to reach an exposed position. The cover plate 200 is slidably disposed on the transverse slide rail 110 and the longitudinal slide rail 120 to close or open the opening. The display screen body 300 is disposed inside the housing 100 and is located below the opening.

[0038] Specifically, both the transverse slide 110 and the longitudinal slide 120 are formed on the inner wall of the housing 100. Both sides of the transverse slide 110 and the longitudinal slide 120 form flanges 130 extending into the housing 100. The ends of the flanges 130 are bent in opposite directions to form anti-detachment gaps. The width of the anti-detachment gaps is smaller than the outer diameter of the pulley 220. The pulley 220 is located inside the two flanges 130. The anti-detachment gaps can prevent the pulley 220 from coming out of the transverse slide 110 and the longitudinal slide 120.

[0039] The transverse slide 110 is horizontally opened on the rear side of the opening, and the longitudinal slide 120 is opened on the rear side of the housing 100. The longitudinal slide 120 is inclined outward from top to bottom, and the longitudinal slide 120 and the transverse slide 110 form an obtuse angle structure, which facilitates the smooth sliding of the cover plate 200 between the transverse slide 110 and the longitudinal slide 120.

[0040] The present invention provides a liftable display screen structure that can realize two states of the display screen body 300, which are raised and lowered. When the car is started, the drive motor 430 drives the drive gear 410 and the driven gear 420 to rotate. The drive gear 410 and the driven gear 420 drive the display screen body 300 to rise through two first connecting rods 440. The drive gear 410 or the driven gear 420 drives the cover plate 200 to slide from the transverse slide rail 110 to the longitudinal slide rail 120 through the second connecting rod 450, thereby opening the opening of the housing 100. At the same time, the display screen body 300 rises to the opened opening. When the car is closed, the drive motor 430 drives the driving gear 410 and driven gear 420 to rotate in opposite directions. The driving gear 410 and driven gear 420 lower the display screen body 300 via two first connecting rods 440. The driving gear 410 or driven gear 420 then slides the cover plate 200 from the longitudinal slide rail 120 to the transverse slide rail 110 via the second connecting rod 450, thereby closing the opening of the housing 100. At the same time, the display screen body 300 descends into the interior of the housing 100. This invention provides a liftable display screen structure where the display screen body 300 is hidden when the car is closed and rises when the car is started, adding a sense of ceremony to the driving experience and preventing the display screen from being constantly exposed, thus reducing the probability of wear and tear.

[0041] Specifically, the housing 100 has a cuboid structure with an open top and a hollow interior. The opening is located directly above the housing 100, occupying the top area of ​​the housing 100, ensuring that the display screen body 300 can rise smoothly to the opening. Both the driving gear 410 and the driven gear 420 are sector gears, with their rotation centers located on the same horizontal line, and their teeth meshing to ensure synchronous rotation.

[0042] When the display screen body 300 is in a hidden state, there is a gap between the display screen body 300 and the cover plate 200 in the direction of its movement. This is to prevent interference when the display screen body 300 and the cover plate 200 move synchronously, and to prevent the display screen body 300 from rising to the cover plate 200 before the cover plate 200 is fully opened, thus avoiding interference between the two.

[0043] Please refer to Figure 5 A side plate 210 is provided on one side of the cover plate 200. The side plate 210 is integrally formed with the cover plate 200 and extends vertically downward. The pivot of the pulley 220 is vertically installed on the outside of the side plate 210. The pulley 220 slides along the transverse slide 110 and the longitudinal slide 120, thereby causing the cover plate 200 to close the opening of the housing 100 or open the opening of the housing 100.

[0044] Optionally, at least two pulleys 220 are installed on the side plate 210 corresponding to each cover plate 200, with at least one pulley installed at each end of the side plate 210, to ensure the stable sliding of the cover plate 200 and to allow it to pass through the junction of the transverse slide 110 and the longitudinal slide 120 as stably as possible.

[0045] Optionally, an arc segment is provided between the transverse slide 110 and the longitudinal slide 120 to ensure that the pulley 220 can smoothly switch between the transverse slide 110 and the longitudinal slide 120.

[0046] Please refer to Figure 5 The cover plate 200 includes at least two, which are arranged in sequence. The two ends of the third link 250 are respectively rotatably connected to the same end of the adjacent cover plate 200. The second link 450 drives one of the cover plates 200 to move, thereby driving the cover plates 200 to move together with each other by means of the third link 250 between the adjacent cover plates 200. The hinged connection between the third link 250 and the adjacent cover plates 200 can ensure that each of the multiple cover plates 200 can pass smoothly in sequence through the junction of the transverse slide 110 and the longitudinal slide 120.

[0047] Please refer to Figure 1 and Figure 2The second connecting rod 450 is located on the outside of the housing 100. The rotating shaft of the driven gear 420 extends through the housing 100 to its outside. One end of the second connecting rod 450 is connected to the rotating shaft of the driven gear 420. One end of the cover plate 200 is provided with a connecting post 240 extending outward from the housing 100. The connecting post 240 passes through the through groove 121. The end of the connecting post 240 that passes through the through groove 121 is hinged to the other end of the second connecting rod 450. When the driven gear 420 rotates, the rotating shaft of the driven gear 420 drives the second connecting rod 450 to rotate around the central axis of the rotating shaft. In order to cooperate with the sliding of the connecting post 240 along the length direction of the through groove 121, a strip groove 451 is opened along the length direction of the second connecting rod 450 on the side away from the driven gear 420. The connecting post 240 passes through the through groove 121 and the strip groove 451. The strip groove 451 can compensate for the relative position of the connecting post 240 and the second connecting rod 450 when the second connecting rod 450 rotates, ensuring that the second connecting rod 450 can smoothly drive the connecting post 240 to slide along the length direction of the through groove 121, thereby driving the cover plate 200 to slide along the length direction of the longitudinal slide rail 120.

[0048] Optional, please refer to Figures 3 to 5 A connecting plate 230 is rotatably connected to one end of the cover plate 200. The end of the connecting plate 230 connected to the cover plate 200 has an arc-shaped structure, allowing smooth passage through the transverse slide 110 and the longitudinal slide 120. The other end of the connecting plate 230 is slidably positioned within the longitudinal slide 120. A connecting post 240 is vertically connected to the end of the connecting plate 230 furthest from the arc-shaped structure. When the cover plate 200 is in the open position, the arc-shaped structure at one end of the connecting plate 230 is located at the end of the transverse slide 110 near the longitudinal slide 120, while the rest of the connecting plate 230 is located within the longitudinal slide 120. When the cover plate 200 is completely removed from the open position, the connecting plate 230 slides to the bottom of the longitudinal slide 120. This configuration of the connecting plate 230 ensures that it slides only within the longitudinal slide 120 without rotation, making the switching between the transverse and longitudinal slides of the cover plate 200 smoother.

[0049] Please refer to Figure 3 and Figure 4 The connecting plate 510 has a right-angled triangular structure. One straight side is set horizontally and is fixed to one side of the display screen body 300 by vulcanization or bonding. The other straight side is set vertically. Multiple mating teeth 511 are integrally formed on the outer side of the vertical straight side from top to bottom. The rotating gear 520 is rotatably set on the inner side of the housing 100. The rotating gear 520 meshes with the mating teeth 511. During the lifting and lowering of the display screen body 300, the connecting plate 510 is lifted and lowered with the display screen body 300, so that the multiple mating teeth 511 set vertically on the connecting plate 510 mesh with the rotating gear 520 in sequence.

[0050] Among them, the rotating gear 520 is installed on the damper. When the connecting plate 510 moves up and down with the help of the mating teeth 511, the damping effect of the damper acts on the rotating gear 520, which enables the display screen body 300 to move up and down smoothly in a damped state.

[0051] Optional, please refer to Figure 1 and Figure 2 The housing 100 has longitudinal grooves 140 on both sides, and the display screen body 300 has guide rods 310 connected to both sides. The number of guide rods 310 and the longitudinal grooves 140 are the same and correspond one-to-one. The guide rods 310 pass through the corresponding longitudinal grooves 140 from the inside to the outside, and the width of the longitudinal grooves 140 is the same as the outer diameter of the guide rods 310. When the display screen body 300 is raised or lowered, the guide rods 310 slide along the length of the longitudinal grooves 140 to ensure the smooth raising and lowering of the display screen body 300.

[0052] Optional, please refer to Figure 1 The bottom of the housing 100 is provided with a wire harness hole 150, through which the wire harness connecting the display screen body 300 passes into the housing 100.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
