[0006] Optionally, the incident angle of the reflection incident angle is configured to make the reflectivity of the glass > 20%.

[0009] Optionally, the glass is configured as a rectangular structure. The glass has a first side edge extending in a first direction and a second side edge extending in a second direction. The first direction and the second direction are perpendicular. In the first direction, the display unit is close to one second side edge of the glass. The irradiation end of the display unit emits light toward the first direction;

[0010] Wherein, the glass is configured as a windshield. The display unit is used to be installed on the vehicle's center console.

[0011] Optionally, the number of the display units is one. The display unit extends in the second direction. In the second direction, the length of the display unit is greater than or equal to half of the length of the glass;

[0025] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, left, right" are usually defined according to the direction of the drawing surface of the accompanying drawings, and "inner, outer" refer to the inside and outside of the relevant components. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present disclosure, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium. It can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0028] With the development of automotive technology, more and more vehicles are equipped with a head-up display, that is, a head-up display system, which uses the lower area of the windshield to reflect an image, so that the driver can observe the road conditions outside the vehicle without looking down and can also observe the relevant information of the vehicle without lowering the head.

[0029] In the head-up display systems of related technologies, the display units all use P light sources, and a reflective film needs to be coated on the glass to achieve the reflective display effect, while coating a reflective film on the glass will increase the manufacturing cost.

[0030] For this reason, as Figures 1 - 3 shown, one aspect of the present disclosure provides a head-up display system, including a glass 1 and a display unit 2.

[0031] The display unit 2 includes a light source 21 and an irradiation end 22. The light source 21 emits light outward through the irradiation end 22. The light source 21 is configured as an S light source 21. The irradiation end 22 faces one side of the glass 1 and is disposed obliquely relative to the glass 1. There is a reflection incident angle 24 between the light emitted by the irradiation end 22 and the glass 1, so that the light emitted by the irradiation end 22 can be reflected by the glass 1.

[0032] Wherein, the display unit 2 can be connected to the vehicle control system. The vehicle control system transmits the information to be displayed to the display unit 2. The relevant information is irradiated by the light source 21 and projected onto the glass 1 through the irradiation end 22.

[0033] Wherein, the relative inclined setting of the irradiation end 22 and the glass 1 can realize the reflection of light, so that the light generated by the irradiation end 22 enters the glass 1 obliquely and then is reflected by the surface of the glass 1.

[0034] In the above technical solution, by setting the light source 21 as an S light source 21, the S light source 21 means that the electric field component of the polarized incident light is perpendicular to the plane formed by the incident light and the reflected light. Due to the characteristics of the polarization state of the S light source 21, the light emitted by the S light source 21 can directly generate a relatively large reflectivity after irradiating the glass 1, so that a display effect can be generated. Therefore, there is no need to additionally coat a reflective film on the glass 1 to increase the reflectivity, which can reduce the manufacturing cost of the glass 1 and thus reduce the manufacturing cost of the whole vehicle.

[0035] Optionally, in an embodiment of the present disclosure, the incident angle of the reflection incident angle 24 is configured to make the reflectivity of the glass 1 > 20%. By setting like this, the reflection effect can be improved and the display brightness and display effect can be ensured. It should be noted that by adjusting the incident angle of the reflection incident angle 24 differently, the reflectivity of the glass 1 can be changed.

[0036] Optionally, in an embodiment of the present disclosure, the incident angle of the reflection incident angle 24 is 60° - 70°. By setting like this, the reflectivity of the glass 1 can be ensured to be > 20%, so that the display effect can be ensured. In some examples, the incident angle of the reflection incident angle 24 can be 60°, 65°, 70°, etc. Of course, it should be noted that the incident angle of the reflection incident angle 24 can also be set to other angle values according to the situation.

[0037] Optionally, in an embodiment of the present disclosure, the display unit 2 further includes an outer frame 23. The outer frame 23 is provided with an installation opening 25. The light source 21 is connected inside the outer frame 23. The irradiation end 22 is connected to the installation opening 25 and partially exposed outside. The irradiation end 22 and the side of the outer frame 23 close to the glass 1 are both configured as arc-shaped structures.

[0038] Among them, the outer frame 23 can be used to protect the light source 21 and the irradiation end 22. The outer frame 23 can adopt a housing structure made of plastic. An installation opening 25 is formed on one side of the outer frame 23. The light source 21 is arranged in the installation opening 25. The irradiation end 22 covers the light source 21, and at the same time, the irradiation end 22 exposes the installation opening 25, so that light can be emitted outward through the irradiation end 22. In some examples, the installation opening 25 is located at the top of the outer frame 23, and the irradiation end 22 can be a screen for display.

[0039] Among them, by constructing the side of the irradiation end 22 close to the glass 1 into an arc structure, it can adapt to the situation where the glass 1 is curved, avoid image distortion of the formed image, and at the same time can assist external related software to further correct the formed image and avoid distortion. It should be noted that the irradiation end 22 has an effective display area, and through correction, an actual display area can be obtained. The actual display area is smaller than the effective display area, and the side of the actual display area close to the glass 1 is in an arc structure. Therefore, the side of the irradiation end 22 close to the glass 1 can be set as an arc structure to make it in a parallel state, which can reduce the size occupation and ensure the display effect at the same time. This can be applicable to the situation where the glass 1 is a windshield 1, and the windshield 1 is generally a quadratic surface. It should be noted that in some other embodiments, if the glass 1 is not curved, the side of the irradiation end 22 close to the glass 1 may not be set as an arc structure.

[0040] Among them, by also constructing the side of the outer frame 23 close to the glass 1 into an arc structure, the outer frame 23 can adapt to the shape structure of the irradiation end 22, reduce the size of the display unit 2, avoid excessive redundant space occupation, and is conducive to being arranged on the vehicle. In addition, by constructing the side of the outer frame 23 close to the glass 1 into an arc structure, it can also adapt to the situation where the glass 1 is a windshield 1 and adapt to the arc structure at the connection between the vehicle's center console and the windshield 1, which is convenient for installing the outer frame 23 on the vehicle's center console. In some examples, the radius of curvature of the arc structures on the sides of the irradiation end 22 and the outer frame 23 close to the glass 1 can be 2300 mm.

[0041] Among them, in some examples, the display unit 2 can be a display screen, such as an LED display screen. The irradiation end 22 can be a screen, and the size of the screen can be 11.98 inches, 12 inches, etc., or other more sizes. The screen has a display area 26, and the edge of the display area 26 can also be set as an arc to improve the correction effect.

[0042] Optionally, in another embodiment of the present disclosure, the display unit 2 further includes an outer frame 23. The outer frame 23 is provided with a mounting opening 25. The light source 21 is connected inside the outer frame 23, and the irradiation end 22 is connected to the mounting opening 25 and partially exposed outside. The irradiation end 22 and the outer frame 23 can be configured into special-shaped structures. The irradiation end 22 and the outer frame 23 can be adjusted according to different usage scenarios, such as adjusted according to the size and shape structure of the installation position.

[0043] Optionally, in one embodiment of the present disclosure, the glass 1 is configured into a rectangular structure. The glass 1 has a first side edge extending in the first direction and a second side edge extending in the second direction. The first direction and the second direction are perpendicular. In the first direction, the display unit 2 is close to one second side edge of the glass 1, and the irradiation end 22 of the display unit 2 emits light in the first direction.

[0044] Among them, the glass 1 is configured as a windshield 1, and the display unit 2 is used for installation on the vehicle's center console. In some examples, the first direction can be the height direction of the vehicle, and the second direction can be the width direction of the vehicle. The display unit 2 is located at the bottom of the glass 1, that is, the light emitted by the irradiation end 22 mainly irradiates on the bottom surface of the glass 1 and is reflected through the bottom of the glass 1 to be displayed at a position close to the bottom of the glass 1, without affecting the driver's observation of the road conditions. In other examples, the first direction can also be the horizontal direction, and the second direction can be the vertical direction, that is, projection display is performed on the side surface of the glass 1.

[0045] Optionally, in another embodiment of the present disclosure, the glass 1 can be configured into a triangle, a circle or other shapes, and can be specifically selected according to the usage scenario of the glass 1. That is to say, the glass 1 can be a side window glass 1 on the vehicle, and the content to be displayed can be projected and displayed on the side window glass 1 as needed.

[0046] Optionally, in one embodiment of the present disclosure, the number of the display units 2 is one. The display unit 2 extends in the second direction. In the second direction, the length of the display unit 2 is greater than or equal to half of the length of the glass 1. By setting like this, panoramic display can be realized, that is, most of the lower part of the entire glass 1 can be displayed, more content can be displayed, so that a continuous and complete picture can be viewed when looking at the lower end of the windshield 1 inside the cockpit, increasing the sense of atmosphere and luxury.

[0047] Optionally, in another embodiment of the present disclosure, the number of display units 2 is multiple, and the multiple display units 2 are arranged at intervals along the second direction. In the second direction, the sum of the lengths of the multiple display units 2 is greater than or equal to half the length of the glass 1. By such an arrangement, a panoramic display can be achieved, that is, most of the lower area of ​​the entire glass 1 can be displayed, and more content can be displayed, so that a continuous and complete picture can be viewed from the lower end of the windshield 1 in the cabin, increasing the atmosphere and luxury.

[0048] It should be noted that the contents displayed by two adjacent display units 2 can be spliced ​​together for common display. The size of the display unit 2 depends on the display image to be displayed according to the size of the display area of ​​the head-up display system. The number and arrangement of the display units 2 can be selected and adjusted according to actual needs.

[0049] Optionally, in one embodiment of the present disclosure, the side of the outer frame 23 of two adjacent display units 2 that is close to each other is constructed as an arc transition to reduce the spacing between the two adjacent display units 2. This arrangement can reduce the space occupied by multiple display units 2 when arranged in parallel, improve space utilization, better adapt to the space between the windshield 1 and the instrument panel of the vehicle, and facilitate reasonable layout with other structures of the center console. It should be noted that the spacing between two adjacent display units 2 can be set according to the actual arrangement, and no excessive restrictions are imposed here.

[0050] Optionally, in one embodiment of the present disclosure, the glass 1 includes a first glass layer 11, a second glass layer 12 and a shielding layer 13, the first glass layer 11 and the second glass layer 12 are connected face to face, there is a gap between the first glass layer 11 and the second glass layer 12, the shielding layer 13 is located in the gap, and the irradiation end 22 of the display unit 2 faces the side of the second glass layer 12 away from the first glass layer 11.

[0051] The first glass layer 11 and the second glass layer 12 have the same size, and the first glass layer 11 and the second glass layer 12 can be bonded and fixed by adhesive parts arranged at the four edges, and the shielding layer 13 is in the gap. The shielding layer 13 can absorb the light emitted by the irradiation end 22, so as to prevent the light from penetrating the first glass layer 11 and the second glass layer 12 and generating double images, thereby ensuring the display effect.

[0052] It can be understood that the light emitted by the irradiation end 22 of the display unit 2 is reflected by the second glass layer 12, and the shielding layer 13 on the first glass layer 11 can also prevent the light from being reflected by the first glass layer 11, thus avoiding ghosting and ensuring the display effect. When the light emitted by the irradiation end 22 is reflected by the second glass layer 12, a virtual image outside the glass 1 can be produced when viewed with the naked eye. The virtual image is the imaging display. The height of the virtual image can be 25 mm - 50 mm, and the width of the virtual image can be 300 mm - 1200 mm, or even wider.

[0053] Optionally, in an embodiment of the present disclosure, the shielding layer 13 is connected to the side of the first glass layer 11 facing the second glass layer 12. The shielding layer 13 is close to the display unit 2. The light emitted by the irradiation end 22 irradiates on the shielding layer 13, and the reflectivity of the shielding layer 13 is less than 1%. By setting it in this way, the light irradiating on the shielding layer 13 can be absorbed as much as possible, avoiding the ghosting problem and improving the display image contrast. In some examples, the shielding layer 13 can be bonded to the side of the first glass layer 11 facing the second glass layer 12. It should be noted that the size of the shielding layer 13 is smaller than the sizes of the first glass layer 11 and the second glass layer 12, that is to say, the shielding layer 13 is provided at the position where the first glass layer 11 and the second glass layer 12 are close to the display unit 2, and is not provided at other positions.
