Display device and vehicle display device

Abstract

A display device includes a base, a linear slide rail, a support, first to fourth transmission devices, a drive device, a guide base, a movable link, and first and second display screens mounted on the base. The support is mounted on the linear slide rail. The second and fourth transmission devices are mounted on the support and the second display screen, respectively. The movable link is mounted on the guide base, with one end fixed to the support. The first display screen is mounted on the movable link. When the movable link moves from a retracted position to an extended position, the drive device drives the first transmission device, which in turn drives the second and third transmission devices. The third transmission device, through the fourth transmission device, moves the second display screen to a position offset from the first display screen. The second transmission device then moves the first display screen to a position where it is aligned with the second display screen.

4. The display device as claimed in claim 1, wherein each of the at least one movable link comprises: a first link having a first end and a second end opposite to each other, wherein the first end is fixed to the support; a second link pivotally connected to the second end, wherein the first display screen is disposed on the second link; and a guide rotatably disposed below the second link and guided by the guide.

5. The display device as described in claim 4, wherein the guide is a ball.

6. The display device as claimed in claim 4, wherein the guide portion has: a first groove extending in the guide base along the first direction; and at least one second groove extending from the first groove toward the second display screen along the second direction.

7. The display device as claimed in claim 6, wherein the number of the at least one movable link is two, and the number of the at least one second slide is two, wherein the guides of the movable links move in the second slides respectively.

8. The display device as described in claim 1, wherein: The first transmission device includes: a first gear, which engages with the drive device; And a belt connecting the first gear and the third transmission device; and the second transmission device is a first rack that extends along the first direction and meshes with the first gear.

9. The display device as described in claim 8, wherein: The third transmission device includes: a second gear connected to the first gear via the belt; a third gear meshing with the second gear; and the fourth transmission device is a second rack extending along the first direction and meshing with the third gear.

10. The display device as claimed in claim 1 further includes a gravity sensor, wherein the gravity sensor is signal-connected to a control device of the drive device.

11. A vehicle display device, comprising: a base disposed in a driver's compartment of a vehicle body; a linear slide rail disposed on the base and extending along a first direction; a support seat disposed on the linear slide rail and slidable along the linear slide rail; a first transmission device disposed on the base; a drive device engaged with the first transmission device and configured to drive the first transmission device; a second transmission device disposed on the support seat, wherein the first transmission device is engaged with the second transmission device to drive the support seat through the second transmission device; a guide base disposed on the base and including a guide portion; at least one movable link disposed on the guide base, wherein one end of each of the at least one movable link is fixed to the support seat, and the at least one movable link moves between a retracted position and an extended position under the guidance of the guide portion; A first display screen is disposed on the at least one movable link, wherein the first direction is a length direction of the first display screen; a third transmission device is disposed on the base, wherein the first transmission device is engaged with the third transmission device to drive the third transmission device; a second display screen is disposed on the base and is movable on the base along the first direction; and a fourth transmission device is disposed on the second display screen, wherein the third transmission device is engaged with the fourth transmission device to drive the second display screen to move along the first direction through the fourth transmission device, wherein when the at least one movable link moves from the retracted position to the extended position, the second display screen moves along the first direction to be offset from the first display screen in a second direction, and the first display screen moves from behind the second display screen along the second direction to be spliced ​​with the second display screen in the first direction, wherein the second direction is a thickness direction of the first display screen.
