[0001] This invention belongs to the field of automotive technology, and more specifically, relates to a retractable display screen structure and an automobile. Background Technology

[0002] Currently, displays used in automobiles are typically installed in either a floating or embedded manner.

[0003] When a car is running or turned off, the display screen is always exposed to the outside, increasing the probability of screen wear and tear. Summary of the Invention

[0004] The purpose of this invention is to provide a liftable display screen structure, which aims to solve the problem that the display screen is always exposed to the outside, increasing the probability of display screen wear.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a liftable display screen structure, comprising:

[0006] A housing, wherein the top of the housing is provided with an opening;

[0007] The display screen body is movably disposed within the housing through the opening, and can be in a hidden state or an extended state;

[0008] A cover plate is movably disposed at the opening position, and the direction of movement of the cover plate is perpendicular to the direction of movement of the display screen body;

[0009] The linkage mechanism includes a first link connected to the display screen body and a second link connected to the cover plate, and the linkage mechanism is adapted to simultaneously control the movement of the display screen body and the cover plate under the action of the drive mechanism.

[0010] In one possible implementation, the drive mechanism includes a drive gear disposed on the housing and a drive motor disposed on the housing for driving the drive gear to rotate, wherein the first connecting rod is hinged to the drive gear and the second connecting rod is fixed to the drive gear.

[0011] In one possible implementation, the drive gear includes a driving gear and a driven gear that mesh with each other, and the drive motor is used to drive the driving gear to rotate;

[0012] The two first connecting rods are respectively fixed to the driving gear and the driven gear, and are used to drive the display screen body to rise or fall;

[0013] The two second connecting rods are respectively hinged to the driving gear and the driven gear, and are used to drive the two cover plates to move laterally closer or further apart.

[0014] In one possible implementation, both the driving gear and the driven gear are fixedly connected to a connecting rod, with the lower end of the first connecting rod hinged to the connecting rod and the upper end hinged to the cover plate.

[0015] In one possible implementation, when the display screen body is in a hidden state, there is a gap between the display screen body and the cover plate in the direction of entry and exit of the display screen body.

[0016] In one possible implementation, the top of the housing is provided with a decorative panel, the opening is located in the middle of the decorative panel, and a reserved gap is provided between the upper edge of the housing and the decorative panel for the cover plate to pass through.

[0017] In one possible implementation, a third link is arranged parallel to the outside of the second link (450), one end of the third link being hinged to the inner wall of the housing and the other end being hinged to the corresponding cover plate.

[0018] In one possible implementation, a connecting plate is connected to one side of the display screen body, and a plurality of mating teeth are longitudinally arranged on one side of the connecting plate. A rotating gear that meshes with the mating teeth is rotatably arranged on the inner side of the housing.

[0019] In one possible implementation, longitudinal grooves are formed on both sides of the housing, and guide rods corresponding to the longitudinal grooves are provided on both sides of the display screen body.

[0032] 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.

[0033] Please see Figures 1 to 6 The present invention will now describe a liftable display screen structure. The liftable display screen structure includes a housing 100, a display screen body 200, a cover plate 300, and a linkage mechanism.

[0034] The housing 100 has an opening at the top, through which the display screen body 200 is movably disposed within the housing 100, and can be in a hidden state or an extended state. The cover plate 300 is movably disposed at the opening position, and the movement direction of the cover plate 300 is perpendicular to the movement direction of the display screen body 200. The linkage mechanism includes a first link 440 connected to the display screen body 200 and a second link 450 connected to the cover plate 300, respectively. The linkage mechanism is adapted to simultaneously control the movement of the display screen body 200 and the cover plate 300 under the action of the drive mechanism.

[0035] This invention provides a liftable display screen structure. Compared with existing technologies, the driving component serves as the power mechanism for the entire device. The driving mechanism drives the first link 440 and the second link 450 in the linkage mechanism to move simultaneously, thereby causing the display screen body 200 and the cover plate 300 to move perpendicularly to each other. This allows the cover plate 300 to cooperate with the display screen body 200 to achieve both a hidden state and an extended state relative to the opening position of the housing 100. With this liftable display screen structure, the display screen body 200 is hidden when the car is closed and extended when the car is started, adding a sense of ceremony to the driving experience. Simultaneously, it avoids the display screen being constantly exposed to the outside, reducing the probability of display screen wear.

[0036] Optionally, the drive mechanism includes a drive motor 430 and a drive gear. The drive gear includes a meshing driving gear 410 and a driven gear 420. The drive motor 430 drives the driving gear 410 to rotate. Two first connecting rods 440 are respectively hinged to the driving gear 410 and the driven gear 420, and are used to simultaneously drive the display screen body 200 to rise or fall. Two second connecting rods 450 are respectively fixed to the driving gear 410 and the driven gear 420, and are used to respectively drive the two cover plates 300 to move laterally closer or further apart.

[0037] 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 200. The two first connecting rods 440 drive the display screen body 200 to rise and fall with the rotation of the drive gear 410 and the driven gear 420. The lower ends of the two second connecting rods 450 are fixedly connected to the edges of the driving gear 410 and the driven gear 420, respectively. The upper ends of the two second connecting rods 450 are rotatably connected to the two cover plates 300. The lower ends of the two second connecting rods 450 rotate synchronously with the driving gear 410 and the driven gear 420, thereby causing the upper ends of the two second connecting rods 450 to move the two cover plates 300 inward or outward at the same time, so that the two cover plates 300 close the opening of the housing 100 or open the opening of the housing 100, so as to enclose the display screen body 200 inside the housing 100 or expose it from the opening of the housing 100.

[0038] The first link 440 and the second link 450 can be a single link or a link group composed of multiple links that extend and retract along a predetermined path. The first link 440 is hinged to the driving gear 410 and the driven gear 420. As the driving gear 410 and the driven gear 420 rotate, its position relative to the axis of the driving gear 410 and the driven gear 420 remains unchanged. The second link 450 is fixed to the driving gear 410 and the driven gear 420. As the driving gear 410 and the driven gear 420 rotate, its position relative to the axis of the driving gear 410 and the driven gear 420 is adjustable.

[0039] This invention provides a liftable display screen structure that allows the display screen body 200 to be in two states: raised and lowered. When the car starts, the drive motor 430 drives the driving gear 410 and driven gear 420 to rotate. The driving gear 410 and driven gear 420 drive the display screen body 200 to rise via two first connecting rods 440. The driving gear 410 and driven gear 420 drive the two cover plates 300 to move outward simultaneously via two second connecting rods 450, thereby opening the opening of the housing 100. At the same time, the display screen body 200 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 drive the display screen body 200 to fall via the two first connecting rods 440. The driving gear 410 and driven gear 420 drive the two cover plates 300 to move inward simultaneously via the two second connecting rods 450, thereby closing the opening of the housing 100. At the same time, the display screen body 200 falls into the housing 100. The present invention provides a liftable display screen structure in which the display screen body 200 is hidden when the car is closed, and the display screen body 200 is raised when the car is started, adding a sense of ceremony to the driving mode, while avoiding the display screen being exposed to the outside all the time, thus reducing the probability of wear and tear on the display screen.

[0040] Specifically, the housing 100 has a cuboid structure with an open top and a hollow interior. A decorative panel 500 is installed at the open top of the housing 100, with the opening located in the center of the decorative panel 500 and directly above the housing 100. The length and width of the opening are not less than the length and width of the display screen body 200, ensuring that the display screen body 200 can smoothly rise to the opening. Both the driving gear 410 and the driven gear 420 are sector gears, with their rotation centers on the same horizontal line, and their teeth meshing to ensure synchronous rotation.

[0041] When the display screen body 200 is in a hidden state, there is a gap between the display screen body 200 and the cover plate 300 in the direction of movement of the display screen body 200. This is to prevent interference when the display screen body 200 and the cover plate 300 move synchronously, and to prevent the display screen body 200 from rising to the cover plate 300 when the cover plate 300 is not fully open, thus avoiding interference between the two.

[0042] Optional, please refer to Figure 2 , Figure 4 and Figure 6Both the driving gear 410 and the driven gear 420 are eccentrically fixed with connecting rods 470. The connecting rods 470 are located inside the second connecting rod 450, and the lower end of the first connecting rod 440 is hinged to the upper end of the connecting rod 470. The connecting rods 470 rotate inwards simultaneously with the driving gear 410 and the driven gear 420, thereby causing the lower ends of the two first connecting rods 440 to rotate inwards, and simultaneously causing the upper ends of the two first connecting rods 440 to move the display screen body 200 downwards. Similarly, the connecting rods 470 rotate outwards simultaneously with the driving gear 410 and the driven gear 420, thereby causing the upper ends of the two first connecting rods 440 to rotate outwards, and simultaneously causing the upper ends of the two first connecting rods 440 to move the display screen body 200 upwards.

[0043] Optional, please refer to Figure 1 and Figure 5 Multiple mounting plates 130 are provided on the upper part of the front outer wall and the upper part of the rear outer wall of the housing 100. These mounting plates 130 are located on the same horizontal plane. The width of the front and rear sides of the decorative panel 500 is greater than the width of the front and rear sides of the housing 100. Multiple connecting bolts are provided on the portion of the decorative panel 500 protruding from the front or rear side of the housing 100, corresponding to the mounting plates 130, for connection with the mounting plates 130. Furthermore, to ensure a pre-reserved gap between the upper edge of the housing 100 and the decorative panel 500, a positioning kit 140 is fitted onto the connecting bolts. This positioning kit 140 limits the distance between the connecting bolts and the mounting plates 130 and the decorative panel 500 when tightened, thereby ensuring the accuracy of the pre-reserved gap.

[0044] The length of the decorative panel 500 is greater than the length of the housing 100, ensuring that the two sides of the decorative panel 500 protrude from the housing 100 by the same distance. When the two cover plates 300 slide outward, they can still remain within the range of the decorative panel 500, resulting in better aesthetics. The width of the reserved gap is slightly greater than the thickness of the cover plate 300, ensuring that the cover plate 300 can pass smoothly through the middle of the reserved gap.

[0045] Optional, please refer to Figure 4The outer side plate 310, front side plate 320, and rear side plate 330 surround the lower part of the cover plate 300 to form a U-shaped structure. The front side plate 320 and rear side plate 330 are parallel to each other and respectively fit against the front and rear outer sides of the housing 100, serving as guides when the cover plate 300 moves laterally. Simultaneously, the front side plate 320 and rear side plate 330 can close the reserved gaps on the front and rear sides between the decorative panel 500 and the upper edge of the housing 100. The outer side plate 310 is perpendicular to the front side plate 320 and rear side plate 330 and connects to their outer ends, limiting the distance the cover plate 300 can move inward. When the two cover plates 300 approach each other to close the opening, the outer side plate 310 fits precisely against the outer wall of the housing 100, thereby closing the reserved gap on the outer side between the decorative panel 500 and the upper edge of the housing 100, ensuring the airtightness of the housing 100.

[0046] Optional, please refer to Figure 2 , Figure 4 and Figure 6 A third link 460 is provided on the outer side of the second link 450, and the third link 460 is arranged parallel to the second link 450. The lower end of the third link 460 is hinged to the inner wall of the housing 100, and the upper end is hinged to the corresponding cover plate 300 and located outside the upper hinge point of the second link 450. The third link 460 rotates synchronously with the second link 450, forming two parallel sides of a quadrilateral structure, which allows the cover plate 300 to move smoothly laterally while also supporting the cover plate 300. In addition, multiple third links 460 can be arranged in parallel on the outer side of each second link 450, and the multiple third links 460 cooperate with the same second link 450 to rotate.

[0047] Please see Figure 2 , Figure 3 and Figure 6 The connecting plate 610 has a right-angled triangular structure. One straight side is set horizontally and is fixed to one side of the display screen body 200 by vulcanization or bonding. The other straight side is set vertically. Multiple mating teeth 611 are integrally formed on the outer side of the vertical straight side from top to bottom. The rotating gear 620 is rotatably set on the inner side of the housing 100. The rotating gear 620 meshes with the mating teeth 611. During the lifting and lowering of the display screen body 200, the connecting plate 610 is lifted and lowered with the display screen body 200, so that the multiple mating teeth 611 set vertically on the connecting plate 610 mesh with the rotating gear 620 in sequence.

[0048] Among them, the rotating gear 620 is installed on the damper 630. When the connecting plate 610 moves up and down with the rotating gear 620 through the mating teeth 611, the damping effect of the damper 630 acts on the rotating gear 620, which enables the display screen body 200 to move up and down smoothly in a damped state.

[0049] Optional, please refer to Figure 4 The housing 100 has longitudinal grooves 110 on both sides, and the display screen body 200 has guide rods 210 connected to both sides. The number of guide rods 210 and the longitudinal grooves 110 are the same and correspond one-to-one. The guide rods 210 pass through the corresponding longitudinal grooves 110 from the inside to the outside, and the width of the longitudinal grooves 110 is the same as the outer diameter of the guide rods 210. When the display screen body 200 is raised or lowered, the guide rods 210 slide along the length of the longitudinal grooves 110 to guide the display screen body 200 to rise and fall smoothly in the longitudinal direction.

[0050] Optional, please refer to Figure 4 The bottom of the housing 100 is provided with a wire harness hole 120, through which the wire harness connecting the display screen body 200 passes into the housing 100.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
