It will be apparent that the described embodiments are only some, but not all, of the embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which a person skilled in the art would obtain without making any inventive effort, are within the scope of the utility model.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1, 2 and 3 together, the present utility model provides a display device 10, where the display device 10 may be applied to a vehicle, for example, the display device 10 may be a HUD device, which may fuse navigation and advanced driving support system (Advanced Driving Assistant System, ADAS) information of the vehicle with a road ahead, and display contents such as steering indication, obstacle warning, lane departure, early warning of a front vehicle, blind area monitoring, etc. on a windshield 20 of the vehicle, so as to help a driver grasp information such as road conditions, etc. to better drive the vehicle.

The display device 10 includes a light emitting module 11, a free-form surface mirror 12, a reflecting module 13, and an adjusting module 14. The light emitting module 11 can output steering instructions, obstacle warnings, lane departure, early warning of a preceding vehicle, blind area monitoring and the like of the vehicle.

In some embodiments, the light emitting module 11 may be an LCD module, so as to help improve the light emitting quality of the light emitting module 11. In other embodiments, the light emitting module 11 may be an LED module, a laser module, or other types of light emitting modules.

The free-form surface mirror 12 is located on the outgoing light path of the light outgoing module 11, and the free-form surface mirror 12 can increase the angle of view of the display device 10, improve aberration, and help to improve the quality of the outgoing light of the display device 10.

The reflective element 13 is located in the outgoing light path of the free-form surface mirror 12, and helps to reduce the height of the free-form surface mirror 12 in the vertical direction, and helps to reduce the space occupied by the display device 10.

For example, the light emitting surface of the light emitting module 11 may be opposite to the reflecting surface of the free-form surface reflecting mirror 12, and the reflecting component 13 is located between the light emitting surface of the light emitting module 11 and the reflecting surface of the free-form surface reflecting mirror 12, so that the light emitted from the light emitting module 11 may propagate to the reflecting component 13 through the free-form surface reflecting mirror 12 and be reflected to the outside of the display device 10 through the reflecting component 13. Thus, the display device 10 is simple and compact in structure and convenient to manufacture.

An adjustment assembly 14 is coupled to the reflective assembly 13, the adjustment assembly 14 being adapted to drive the reflective assembly 13 to move to change the imaging position of the display device. Wherein the adjustment assembly 14 may be adapted to drive the rotation of the reflective assembly 13.

Illustratively, the adjustment assembly 14 is adapted to drive the reflective assembly 13 to a first position, the display device 10 having a first light exit direction; the adjusting component 14 is adapted to drive the reflecting component 13 to move to the second position, and the display device 10 has a second light emitting direction different from the first light emitting direction. In this way, the adjusting component 14 helps to meet the requirements of the display device 10 with different light emitting directions by adjusting the position of the reflecting component 13, and the display device 10 is applied to head-up display to meet the requirements of the driver with different fields of view.

As shown in fig. 3, when the adjusting component 14 drives the reflecting component 13 to move to the first position, the included angle between the reflecting component 13 and the horizontal plane is β1, the windshield 20 can receive the outgoing light path of the display device 10 in the first light emitting direction, the windshield 20 can reflect the received light to the eye position a of the driver, the driver can observe information such as road conditions through the windshield 20, and the included angle between the connecting line between the windshield 20 and the position a and the vertical plane is α.

When the display position of the road condition information on the windshield 20 is low and is unfavorable for the observation of a driver, the driver can adjust the adjusting component 14 to drive the reflecting component 13 to move to the second position, at this time, the included angle between the reflecting component 13 and the horizontal plane is beta 2, the windshield 20 can receive the emergent light path of the display device 10 in the second emergent light direction, the windshield 20 can reflect the received light to the human eye position B of the driver, the driver can observe the road condition and other information through the windshield 20, and at this time, the included angle between the connecting line of the windshield 20 and the position B and the vertical plane is alpha.

The outgoing light beam of the display device 10 reflected by the windshield 20 in the outgoing light path of the first light emitting direction is parallel to the outgoing light beam of the display device 10 reflected by the windshield 20 in the outgoing light path of the second light emitting direction, and at this time, the human eye position a of the driver reaches the virtual image point a ₁ Connecting line between the position B of human eyes of driver and virtual image point B ₁ The angle of the line at the location remains consistent, helping to ensure that drivers at different height positions can see the outgoing light rays of the display device 10 from an optimal angle.

The reflecting component 13 can also move to other positions such as a third position, a fourth position, a fifth position, etc. under the driving action of the adjusting component 14, at this time, the display device 10 correspondingly has other light emitting directions such as a third light emitting direction, a fourth light emitting direction, a fifth light emitting direction, etc., so that the display device 10 can be adjusted to be at different positions under the action of the adjusting component 14, which is helpful for meeting the use requirements of drivers under different fields of view.

Thus, the adjusting assembly 14 is helpful for meeting the adjusting requirements of the driver driving the vehicle when the driver is at different height positions, and the adjusting assembly 14 is also helpful for meeting the adjusting requirements of the driver driving the vehicle with different heights, so as to avoid the influence of the higher or lower information display positions such as road conditions on the windshield 20 on the normal observation of the driver.

The display device 10 may have a plurality of preset positions, where the plurality of preset positions may respectively correspond to drivers with different heights, for example, the position of the display device 10 having the first light emitting direction may be the first preset position, the position of the display device 10 having the second light emitting direction may be the second preset position, the position of the display device 10 having the third light emitting direction may be the third preset position, the position of the display device 10 having the fourth light emitting direction may be the fourth preset position, the position of the display device 10 having the fifth light emitting direction may be the fifth preset position, and the display device 10 may store the plurality of preset positions, and when drivers with different heights drive the vehicle, the display device 10 may be adjusted to the corresponding preset position, thereby meeting the use requirement under the condition that the vision of the drivers with different heights is different.

In some embodiments, the reflecting component 13 is rotatably located on one side of the free-form surface mirror 12, for example, the reflecting component 13 can be rotated to one side of the reflecting surface of the free-form surface mirror 12 by the adjusting component 14, so as to help ensure that the reflecting component 13 better receives the reflected light of the free-form surface mirror 12.

The reflecting component 13 may be a plane mirror, and the plane mirror may receive the light reflected by the free-form surface reflecting mirror 12, so as to help ensure the normal operation of the display device 10.

Referring to fig. 4, in some embodiments, the reflective component 13 may include a plurality of prismatic microstructures 135, where each of the plurality of prismatic microstructures 135 includes a prismatic reflective surface 1351 facing the free-form surface mirror 12, and the prismatic reflective surface 1351 is a reflective surface of the reflective component 13, for example, the prismatic reflective surface 1351 may be a metal coating or a reflective paint, so as to help increase the reflection efficiency of the display device 10 on light.

The prism reflecting surface 1351 may have a certain inclination angle with respect to the horizontal plane, and the inclination angle may be 3 degrees to 30 degrees, for example, the inclination angle of the prism reflecting surface 1351 may be 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 30 degrees, or any value between the two adjacent angles. This helps to increase the angle of the light reflected by the reflecting element 13 (the angle between the incident light and the outgoing light), thereby helping to reduce the height of the free-form surface mirror 12 in the vertical direction and helping to reduce the space occupied by the display device 10.

The adjustment assembly 14 is adapted to drive the reflective assembly 13 to selectively rotate to either the first position or the second position. When the adjusting component 14 drives the reflecting component 13 to rotate to the first position, the windshield 20 can receive the emergent light path of the display device 10 in the first emergent light direction; when the adjusting component 14 drives the reflecting component 13 to rotate to the second position, the windshield 20 can receive the outgoing light path of the display device 10 in the second light outgoing direction, so that the reflecting component 13 can be guaranteed to be quickly adjusted to meet the use requirement.

In some embodiments, the adjustment assembly 14 includes a rotary driving member 141 and a rotary shaft 142 connected, the rotary driving member 141 may be a rotary motor, and the driving end of the rotary driving member 141 is connected to the rotary shaft 142, so that the rotary driving member 141 may drive the rotary shaft 142 to rotate about the axis of the rotary shaft 142. The rotation shaft 142 is connected to the reflection assembly 13, and when the rotation driving member 141 drives the rotation shaft 142 to rotate around the axis of the rotation shaft 142, the reflection assembly 13 can synchronously rotate around the axis of the rotation shaft 142 under the action of the rotation shaft 142, so that the position of the reflection assembly 13 is adjusted.

The reflecting surface of the reflecting component 13 faces the reflecting surface of the free-form surface reflecting mirror 12, that is, the included angle between the reflecting surface of the reflecting component 13 and the reflecting surface of the free-form surface reflecting mirror 12 is smaller than 90 degrees, which helps to ensure that the reflecting surface of the free-form surface reflecting mirror 12 can reflect light to the reflecting surface of the reflecting component 13.

The rotating shaft 142 is located at a side of the reflecting surface facing away from the reflecting component 13, so that the rotating shaft 142 can drive the reflecting component 13 to adjust the position, and the rotating shaft 142 is also helpful to avoid shielding the emergent light path of the reflecting component 13 by the rotating shaft 142 under the condition of ensuring that the rotating shaft 142 and the reflecting component 13 work normally.

In some embodiments, the reflective assembly 13 has a first side 131, a second side 132, a third side 133, and a fourth side 134 connected in sequence, the first side 131 being opposite the third side 133, the second side 132 being opposite the fourth side 134. The first side 131 faces the light emitting module 11, and the third side 133 faces the free-form surface mirror 12.

Since the first side portion 131 faces the light emitting module 11, the third side portion 133 faces the free-form surface reflector 12, that is, the reflecting component 13 is located between the light emitting module 11 and the free-form surface reflector 12, and at this time, the reflecting surface of the reflecting component 13 may face the reflecting surface of the free-form surface reflector 12, so that the free-form surface reflector 12 may receive the outgoing light of the light emitting module 11 and reflect the outgoing light to the reflecting component 13, and the reflecting surface of the reflecting component 13 receives the outgoing light of the free-form surface reflector 12 and reflects the outgoing light to the outside of the display device 10, which helps to ensure the normal operation of the display device 10.

The rotation shaft 142 extends from the second side 132 in the direction of the fourth side 134. Illustratively, the rotating shaft 142 may extend from the second side 132 in the direction of the fourth side 134 and penetrate the second side 132 and the fourth side 134, which helps to ensure that the rotating shaft 142 has a sufficient size and helps to ensure that the rotating shaft 142 may better rotate the reflective assembly 13.

The second side 132 faces the rotary driving member 141, and the driving end of the rotary driving member 141 is connected to the end of the rotary shaft 142, so that when the rotary driving member 141 works, the rotary driving member 141 can drive the rotary shaft 142 to rotate, which helps to ensure the normal work of the adjusting assembly 14. Since the second side 132 faces the rotation driving part 141, the rotation driving part 141 contributes to improving the compactness of the structure of the display device 10, and the rotation driving part 141 does not occupy the space of the display device 10 in the vertical direction, thereby contributing to reducing the volume of the entire display device 10.

In some embodiments, the display device 10 may further include a housing 15 and a protective cover 16, where the light emitting module 11, the free-form surface mirror 12, the reflecting component 13, and the adjusting component 14 are all installed in the housing 15, so that the housing 15 may provide a certain protection for the devices such as the light emitting module 11, the free-form surface mirror 12, the reflecting component 13, and the adjusting component 14, and help to avoid damage to the devices in the housing 15 due to exposure.

The protective cover 16 may have a light-transmitting portion 161, where the light-transmitting portion 161 is located on the light path of the reflection assembly 13, so that the light-transmitting portion 161 can satisfy the emission of the light emitted by the reflection assembly 13, thereby helping to maintain the normal operation of the display device 10. In addition, the protective cover 16 helps to prevent dust, particles and other impurities from entering the housing 15, and helps to prevent dust, particles and other impurities from affecting efficient operation of devices in the housing 15.

In some embodiments, the display device 10 may further include a filter 17, the filter 17 covering the light-transmitting portion 161. The filter 17 may be a polarizing film, so that the filter 17 may filter out unwanted stray light of the display device 10, for example, the filter 17 may filter out a portion of sunlight, which helps to reduce the risk of temperature rise of the light emitting module 11 caused by retroreflection of sunlight along the optical path of the display device 10, thereby helping to operate the display device 10 more efficiently. Wherein the filter 17 is shown in fig. 1 as a part of a structure.

The display device 10 may further include a heat dissipation element 19, where the heat dissipation element 19 may be disposed on a side of the light emitting module 11 away from the free-form surface reflector 12, and the heat dissipation element 19 may dissipate heat of the light emitting module 11, so as to help avoid the excessive temperature of the light emitting module 11 during operation, and affect the normal operation of the display device 10.
