Description

Technical Field

[0002] With the development of automotive intelligence, in-vehicle display screens, as important interfaces for human-machine interaction, their performance and user experience have become increasingly important. MiniLED display screens have been widely used in the field of in-vehicle displays due to their advantages such as high brightness, high contrast, and long lifespan. However, existing in-vehicle MiniLED display screens have some deficiencies in design, especially in terms of curvature adjustment and heat dissipation.

[0003] Most existing in-vehicle MiniLED display screens adopt curved modules with a fixed curvature. This design cannot be flexibly adjusted according to the specific needs of users, thus affecting the visual effect and practicality.

[0033] A frame 3 is provided on the base 1; a sliding seat 4 is slidably arranged on the frame 3; a pressure roller 5 is rotatably arranged at one end of the sliding seat 4 close to the flexible screen 2; the pressure roller 5 abuts against the middle part of the flexible screen 2; the vehicle-mounted MiniLED display screen structure with a curved surface structure further includes a driving component for driving the sliding seat 4 to slide.

[0034] Specifically, when the vehicle-mounted MiniLED display screen structure with a curved surface structure described in this embodiment is in use, the user can make the sliding seat 4 slide back and forth through the driving component. During the process of the sliding seat 4 moving towards the flexible screen 2, the pressure roller 5 pushes the middle part of the back surface of the flexible screen 2, so as to change the bending curvature of the flexible screen 2; when the sliding seat 4 moves towards the frame 3, the flexible screen 2 can automatically reset by its own elasticity and gradually return to a flat state.

[0035] A vehicle-mounted MiniLED display screen structure with a curved surface structure according to this embodiment, the driving assembly includes a motor 6 arranged on the base 1, a cam 7 rotatably arranged on the frame 3, and a driving rod 61 rotatably arranged on the frame 3; the output end of the motor 6 is connected to the bottom of the driving rod 61; a ratchet 62 is arranged in the middle of the driving rod 61; a first ratchet tooth 71 cooperating with the ratchet 62 is arranged on the top of the cam 7;

[0036] The driving assembly further includes a roller 41 and a first tension spring 42; the roller 41 is rotatably arranged at one end of the sliding seat 4 away from the flexible screen 2; the first tension spring 42 is arranged between the sliding seat 4 and the frame 3; under the action of the first tension spring 42, the roller 41 abuts against the outer peripheral wall of the cam 7.

[0037] Specifically, for the vehicle-mounted MiniLED display screen structure with a curved surface structure according to this embodiment, when it is necessary to adjust the bending curvature of the flexible screen 2, the driving motor 6 rotates forward, the motor 6 drives the driving rod 61 to rotate forward, and under the cooperation of the ratchet 62 and the first ratchet tooth 71, the ratchet 62 drives the cam 7 to rotate forward. Since the roller 41 and the outer peripheral wall of the cam 7 always abut against each other under the action of the first tension spring 42, during the forward rotation of the cam 7, the cam 7 can push the roller 41 and the sliding seat 4 towards the flexible screen 2, thereby changing the bending curvature of the flexible screen 2.

[0041] Specifically, when the motor 6 drives the driving rod 61 to rotate in the reverse direction, with the cooperation of the ratchet 62 and the first ratchet tooth 71, and under the action of the second ratchet tooth 72 and the pawl 31, the cam 7 remains stationary, that is, the sliding seat 4 maintains its current position, and the bending curvature of the flexible screen 2 remains unchanged; when the driving rod 61 rotates in the reverse direction, through the linkage of the first bevel gear 63, the second bevel gear 64, the first connecting rod 65, the second connecting rod 67, the third bevel gear 66 and the fourth bevel gear 68, the rotor 52 is driven to rotate, so as to generate air flow to dissipate heat from the flexible screen 2. It can effectively avoid the accumulation of a large amount of heat caused by stress concentration due to the bending of the flexible screen 2, ensure that the flexible screen 2 can maintain good working performance in various curvature states, reduce display failures and safety hazards caused by overheating, and improve the overall reliability and safety of the vehicle-mounted display screen.
