Description

[0002] With the development of intelligent vehicles, the performance and user experience of in-vehicle displays, as an important interface for human-computer interaction, are becoming increasingly important.

[0031] The present invention is further described in conjunction with the following examples.

[0032] Depend on Figures 1 to 10 It can be seen that the structure of a vehicle-mounted MiniLED display screen with a curved surface structure described in this embodiment includes a base 1 and a flexible screen 2; the base 1 is provided with a first horizontal groove 11 and a second horizontal groove 12 on both sides; the flexible screen 2 is provided with a first slide bar 21 and a second slide bar 22 on both sides; the first slide bar 21 and the second slide bar 22 are slidably arranged in the first horizontal groove 11 and the second horizontal groove 12 respectively;

[0033] The base 1 is provided with a frame 3; the frame 3 is slidably provided with a sliding seat 4; the sliding seat 4 is rotatably provided with a pressure roller 5 at one end 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 structure also includes a driving component for driving the sliding seat 4 to slide.

[0034] Specifically, when using the vehicle-mounted MiniLED display screen structure with a curved surface structure described in this embodiment, the user can use the driving component to make the sliding seat 4 slide back and forth. In the process of the sliding seat 4 moving toward the direction of the flexible screen 2, the pressure roller 5 pushes the middle part of the back side of the flexible screen 2, thereby changing the bending curvature of the flexible screen 2; when the sliding seat 4 moves toward the direction of the frame 3, the flexible screen 2 can automatically reset itself by its own elasticity, thereby gradually returning to a flat state.

[0035] In the embodiment of the present invention, a MiniLED display screen structure with a curved surface structure is provided. The driving assembly includes a motor 6 provided on a base 1, a cam 7 rotatably provided on a frame 3, and a driving rod 61 rotatably provided 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 provided in the middle of the driving rod 61; and a first ratchet 71 cooperating with the ratchet 62 is provided at the top of the cam 7;

[0036] The driving assembly also 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 described in this embodiment, when it is necessary to adjust the bending curvature of the flexible screen 2, the driving motor 6 rotates forward, and the motor 6 drives the driving rod 61 to rotate forward. With the cooperation of the ratchet 62 and the first ratchet tooth 71, the ratchet 62 drives the cam 7 to rotate forward. Because the roller 41 and the outer peripheral wall of the cam 7 are always in contact with each other under the action of the first tension spring 42, the cam 7 can push the roller 41 and the sliding seat 4 to move in the direction of the flexible screen 2 during the forward rotation of the cam 7, thereby changing the bending curvature of the flexible screen 2.

[0038] In the curved structure of the vehicle-mounted MiniLED display screen described in this embodiment, the bottom of the cam 7 is provided with a second ratchet 72; the frame 3 is provided with a ratchet 31 that cooperates with the second ratchet 72. Specifically, through the above arrangement, it can be ensured that when the motor 6 drives the driving rod 61 to rotate in the opposite direction, the cam 7 can be fixed.

[0039] In the curved MiniLED display structure for vehicles described in this embodiment, a rotor 52 is provided in the pressure roller 5 for rotation; and a venting groove 51 is provided through the pressure roller 5. Through the above arrangement, when the rotor 52 rotates, airflow can be generated to dissipate heat for the flexible screen 2.

[0040] The present embodiment describes a structure of a vehicle-mounted MiniLED display screen with a curved surface structure, wherein a first bevel gear 63 is provided on the top of the driving rod 61; a second bevel gear 64 is rotatably provided on the top of the frame 3; the first bevel gear 63 is meshed with the second bevel gear 64; the second bevel gear 64 is connected to a first connecting rod 65; a third bevel gear 66 and a fourth bevel gear 68 are rotatably provided on the top of the sliding seat 4; the third bevel gear 66 is meshed with the fourth bevel gear 68; the third bevel gear 66 is connected to a second connecting rod 67; the second connecting rod 67 is slidably sleeved outside the first connecting rod 65; the first connecting rod 65 and the second connecting rod 67 are surface-matched; the fourth bevel gear 68 is connected to the rotor 52.

[0041] Specifically, when the motor 6 drives the driving rod 61 to rotate in the reverse direction, the cam 7 remains stationary under the cooperation of the ratchet 62 and the first ratchet 71, and under the action of the second ratchet 72 and the pawl 31, that is, the sliding seat 4 maintains the current position, and the bending curvature of the flexible screen 2 remains unchanged; when the driving rod 61 rotates in the reverse direction, the rotor 52 is driven to rotate 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, so that airflow can be generated to dissipate heat for the flexible screen 2. It can effectively avoid the accumulation of a large amount of heat caused by stress concentration caused by bending of the flexible screen 2, ensure that the flexible screen 2 can maintain good working performance under 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.

[0042] In the curved MiniLED display screen structure for vehicles described in this embodiment, the frame 3 is provided with a guide rod 32; the sliding seat 4 is provided with a guide sleeve 43; the guide sleeve 43 is slidably sleeved outside the guide rod 32. The above arrangement can ensure the sliding stability of the sliding seat 4.

[0043] In the structure of a vehicle-mounted MiniLED display screen with a curved surface structure described in this embodiment, the base 1 is provided with a plurality of heat dissipation groups along the length direction of the flexible screen 2; each heat dissipation group includes a fixed heat dissipation fin 81 and a movable heat dissipation fin 82; one end of the movable heat dissipation fin 82 is hinged to the flexible screen 2; a heat-conducting hinge rod 83 is provided between one end of the movable heat dissipation fin 82 and the flexible screen 2; the other end of the movable heat dissipation fin 82 is slidably sleeved on one end of the fixed heat dissipation fin 81. Specifically, through the above arrangement, when the flexible screen 2 protrudes outward, under the action of the heat-conducting hinge rod 83, the movable heat dissipation fin 82 can be driven to move outward, thereby increasing the total heat dissipation area of ​​the heat dissipation group and further accelerating the heat dissipation efficiency.

[0044] In the curved structure of the vehicle-mounted MiniLED display screen described in this embodiment, a second tension spring 84 is provided between the movable heat dissipation fin 82 and the base 1. Through the above arrangement, when the sliding seat 4 moves in the direction of the sliding seat 4 toward the frame 3, the flexible screen 2 can automatically reset by its own elasticity, thereby gradually returning to a planar state. At the same time, under the action of the second tension spring 84, the middle of the back of the flexible screen 2 can always abut against the pressure roller 5, thereby ensuring that the flexible screen 2 returns to a planar state.

[0045] The present embodiment describes a structure of a vehicle-mounted MiniLED display screen with a curved structure, wherein the base 1 is provided with a water tank 9, a water inlet pipe 91 and a water outlet pipe 92; the water inlet pipe 91 and the water outlet pipe 92 are respectively connected to the water tank 9; a fixed heat dissipation cavity 85 is provided in the fixed heat dissipation fin 81; a movable heat dissipation cavity 86 is provided in the movable heat dissipation fin 82; one end of the fixed heat dissipation fin 81 is telescopically and movably arranged in the movable heat dissipation cavity 86; the movable heat dissipation cavity 86 is connected to the fixed heat dissipation cavity 85; the water inlet pipe 91 is arranged at the top of the other end of the fixed heat dissipation fin 81; the water outlet pipe 92 is arranged at the bottom of the other end of the fixed heat dissipation fin 81; a water inlet check valve 93 is provided between the fixed heat dissipation cavity 85 and the water inlet pipe 91; a water outlet check valve 94 is provided between the fixed heat dissipation cavity 85 and the water outlet pipe 92.

[0046] Specifically, the vehicle-mounted MiniLED display screen structure with a curved structure described in this embodiment is equipped with a water tank 9, in which coolant is provided, so that coolant flows through the movable heat dissipation cavity 86, the fixed heat dissipation fins 81, and the fixed heat dissipation cavity 85, thereby further accelerating the heat dissipation and cooling of the flexible screen 2.

[0047] In addition, during the movement of the movable cooling fins 82, the volume of the movable cooling chamber 86 can be continuously changed. Under the action of the water inlet check valve 93 and the water outlet check valve 94, the coolant can flow between the water tank 9, the movable cooling chamber 86 and the fixed cooling chamber 85 according to the total volume of the movable cooling chamber 86 and the fixed cooling chamber 85.

[0048] In the curved structure of the vehicle-mounted MiniLED display screen described in this embodiment, the side surface of the flexible screen 2 and the top surface of the flexible screen 2 are connected with a flexible folding cover 23. Specifically, through the above arrangement, the flexible folding cover 23 is connected to the center console 10 of the car, so that when the flexible screen 2 changes its bending curvature, the sealing between the center console 10 and the flexible screen 2 can be ensured.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention.
