Abstract

An on-board head up display (HUD) includes a housing, a support member rotatably connected to the housing, a display screen being transparent and flat, and a side of the display screen is fixed to the support member, and a control device located in the housing and configured to obtain traveling information from an on-board automatic diagnostic system, and the control device is further connected to the display screen and configured to display the traveling information on the display screen, and the control device is connected to the support member and configured to drive the support member to rotate with respect to the housing.

Claims

1. An on-board head up display (HUD), comprising:

a housing;

a support member rotatably connected to the housing;

a display screen being transparent and flat, wherein a side of the display screen is fixed to the support member; and

a control device located in the housing and configured to obtain traveling information from an on-board automatic diagnostic system, wherein the control device is further connected to the display screen and configured to display the traveling information on the display screen, and wherein the control device is connected to the support member and configured to drive the support member to rotate with respect to the housing.

2. The on-board HUD of claim 1, wherein the display screen is a transparent organic light-emitting display (TOLED) screen.

3. The on-board HUD of claim 1, further comprising a pivot formed on the support member, wherein the pivot is rotatably connected to the housing, and the support member and the display screen are capable of rotating with respect to the housing about an axis of the pivot.

4. The on-board HUD of claim 3, wherein the control device comprises a main control unit (MCU) and a driver motor connected to the MCU, and the driver motor is connected to the support member to drive the support member to rotate.

5. The on-board HUD of claim 4 wherein the control device further comprises a rotation rheostat and a voltage detecting device connected to the rotation rheostat, the rotation rheostat is connected to the pivot and rotates along with the pivot, the voltage detecting device detects a voltage applied to both ends of the rotation rheostat and stores a detection result in the MCU.

6. The on-board HUD of claim 5, wherein the display screen has three statuses comprising:

an open status where the display screen is drove by the driver motor to rotate to having an largest intersection angle with an upper surface of the housing;

a closed status where the display screen is drove by the driver motor to rotate reversely to be in contact with the upper surface of the housing; and

an target position where the display screen is manually rotated to a position between the open status and the closed status.

7. The on-board HUD of claim 6, wherein the voltage applied to both ends of the rotation rheostat comprises:

a first voltage corresponding to the closed status;

a second voltage corresponding to the largest open status; and

a third voltage corresponding to the target position.

8. The on-board HUD of claim 7, wherein the MCU is configured to control the driver motor to stop rotation when the voltage detecting device detects that a voltage applied to both ends of the rotation rheostat is equal to the third voltage.

9. The on-board HUD of claim 1, wherein the control device comprises a MCU and a tire pressure detecting and receiving unit (TPDRU), the TPDRU comprises a main board and a wireless data transmission card integrated on the main board, the wireless data transmission card is in wireless connection with a tire pressure sensor mounted on a tire, and both of the main board and the display screen are connected to the MCU.

10. The on-board HUD of claim 9, wherein the tire pressure detecting and receiving device is removably connected to the MCU, the housing defines a receiving slot configured to receive the tire pressure detecting and receiving device.

11. The on-board HUD of claim 1, wherein the control device is in wireless connection with the on-board automatic diagnostic system;

12. The on-board HUD of claim 1, wherein the on-board automatic diagnostic system has an output interface, the control device is connected to the output interface through a data transmission cable.

13. The on-board HUD of claim 1, wherein there are a plurality pieces of the traveling information which are displayed on the display screen in a form of a plurality of information blocks;

wherein each information block corresponds to one piece of traveling information.

14. The on-board HUD of claim 1, wherein there are a plurality pieces of the traveling information which are displayed on the display screen in a form of a plurality of information blocks;

wherein each information block corresponds to a combination of a plurality pieces of the traveling information.

15. The on-board HUD of claim 13 wherein the display screen is divided into a plurality of display regions, each display region displays at least one of the information blocks, and displaying colors of two adjacent display regions are different.

16. The on-board HUD of claim 14, wherein the display screen is divided into a plurality of display regions, each display region displays at least one of the information blocks, and displaying colors of two adjacent display regions are different.
