[0042] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0043] Reference will be made below to Figures 1 - 6 Describe an in-vehicle head-up display system 100 for a vehicle according to an embodiment of the present invention. Among them, the vehicle may have a display control system, the display control system may have a plurality of display data, and the plurality of display data may represent a plurality of information of the vehicle. For example, the display control system may have the vehicle speed, engine speed, in-vehicle navigation information, as well as multimedia, driving recorder, brake, throttle and other information. The user can obtain the display information of the above display control system through the in-vehicle head-up display system 100.

[0044] The in-vehicle head-up display system 100 for a vehicle according to an embodiment of the present invention may include: a PCB board 2, an image production optical machine 3 (PGU, Picture Generation Unit), a mirror 4, a support frame 5, and a display member 6.

[0045] Among them, the PCB board 2 can be electrically connected to the display control system to process the display data of the display control system, and the image production optical machine 3 can be electrically connected to the PCB board 2 to generate a display image corresponding to the display control system. Specifically, the display control system can transmit the display data corresponding to the display information to the PCB board 2 by means of wired connection or wireless transmission. The PCB board 2 has a plurality of electronic components such as chips, etc., so that the PCB board 2 can process the display data and transmit it to the image production optical machine 3. The image production optical machine 3 can process the data from the PCB and synthesize it into a display image corresponding to the display system.

[0046] As Figure 5 shown, the mirror 4 can be arranged opposite to the image emission end 3a of the image production optical machine 3, and the display image can be projected onto the mirror 4. The display member 6 is rotatably arranged on the support frame 5, and the display member 6 can be located in the light reflection path of the mirror 4 to present the display image on the side of the display member 6 facing away from the mirror 4. Specifically, the image production optical machine 3 can include a light regulator and a light-emitting display screen. The light regulator can magnify the display image, and the light-emitting display screen is located at the end of the image emission end 3a. The display image can be formed on the light-emitting display screen. The image emission end 3a can project light onto the mirror 4, and the mirror 4 can reflect the light to the display member 6. The display member 6 can present the display image on the side of the display member 6 facing away from the mirror 4 (for example, Figure 5 the front side in Figure 5 ), so as to present the display image in front of the driver 200. For example, the display image can be presented directly in front of the driver 200, thereby improving the eye comfort of the driver 200 and preventing the driver 200 from getting eye fatigue. Among them, "presenting the display image on the side of the display member 6 facing away from the mirror 4" can be understood as presenting the display image on the side of the display member 6 facing away from the mirror 4 (for example, Figure 5 the front side in

[0047] It can be understood that since the display member 6 is rotatably provided on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to actual usage requirements, so that the position of the displayed image can be adjusted, enabling the in-vehicle head-up display system 100 to adapt to drivers 200 of different heights and different driving habits. Thus, the in-vehicle head-up display system 100 has good applicability and practicability, and can make the displayed image located in front of the driver 200. For example, it can make the displayed image located directly in front of the driver 200. When the driver 200 is driving the vehicle, the driver 200 can obtain the display information of the display control system through the displayed image without switching the line of sight, which not only brings great convenience to the actual operation of the driver 200, but also improves the driving safety of the vehicle. Among them, the rotation angle between the display member 6 and the support frame 5 can be manually adjusted for the convenience of the driver 200 to operate, but it is not limited to this. For example, it can also be electronically controlled.

[0048] For the in-vehicle head-up display system 100 for a vehicle according to an embodiment of the present invention, by providing the image production optical machine 3, the reflector 4 and the display member 6, the overall structure of the in-vehicle head-up display system 100 can be made simpler and the operation more convenient. By providing that the display member 6 is rotatably provided on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to actual usage requirements, whereby the displayed image can be located directly in front of the driver 200. When the driver 200 is driving the vehicle, the driver 200 can obtain the display information of the display control system through the displayed image without switching the line of sight, which not only brings great convenience to the actual operation of the driver 200, but also improves the driving safety of the vehicle.

[0049] According to some embodiments of the present invention, the display member 6 can be an optical reflection lens, whereby the display effect of the display member 6 can be improved. Specifically, the optical reflection lens can have a polarization beam splitting film. The projection light reflected by the reflector 4 is reflected to the optical reflection lens, and after being reflected and refracted by the polarization beam splitting film, a projection virtual image (i.e., the displayed image) is formed on the side of the display member 6 facing away from the reflector 4, that is, a projection virtual image is formed in front of the driver 200. The driver 200 can see the above projection virtual image (or optical virtual image) through the display member 6. The optical reflector can perform distortion image correction on the displayed image, preventing the displayed image from being distorted, thereby improving the display effect of the display member 6. Moreover, the optical reflector has a good light transmission effect, and the part of the optical reflection lens other than the displayed image can be formed as a transparent member, whereby the display member 6 can be prevented from blocking the windshield of the vehicle, thus also improving the driving safety. It can be understood that the above projection virtual image can be located in front of the windshield of the vehicle.

[0050] As Figure 3As shown, according to some embodiments of the present invention, the in-vehicle head-up display system 100 may further include a box body 1. The image production optical machine 3, the PCB board 2, the mirror 4, and the support frame 5 may be respectively installed on the box body 1. Thus, the box body 1 can integrate the image production optical machine 3, the PCB board 2, the mirror 4, and the support frame 5, making the overall structure of the in-vehicle head-up display system 100 more compact and facilitating installation and handling.

[0051] As Figure 3 shown, in some embodiments of the present invention, the mirror 4 may be provided on a side wall of the box body 1 opposite to the image emission end 3a of the image production optical machine 3. For example, as Figure 3 shown, the image production optical machine 3 may be provided inside the box body 1. The image production optical machine 3 may include a body and an image emission end 3a. The image emission end 3a is located at the rear end of the body, and the mirror 4 is located on the rear side wall of the box body 1. Thus, through the above arrangement, the image emission end 3a is disposed opposite to the mirror 4, which can improve the image reflection effect of the mirror 4 and further improve the display effect of the display member 6. Of course, it can be understood that the assembly positions between the mirror 4 and the image production optical machine 3 are not limited to this. As long as light can be transmitted between the image production optical machine 3, the mirror 4, and the display member 6 and a display image can be formed on the display member 6.

[0052] In some embodiments of the present invention, the mirror 4 may be in plug-in fit with the box body 1, which can make the cooperation mode between the mirror 4 and the box body 1 simpler and facilitate the installation and replacement of the mirror 4. It can be understood that the cooperation mode between the mirror 4 and the box body 1 is not limited to this. For example, in Figures 1 - 2 the specific example shown, the mirror 4 may include a lens 42 and a frame 41. The lens 42 is embedded in the frame 41. The frame 41 may be connected to the box body 1 by screws or rivets, or the frame 41 may be integrally formed with the box body 1. Thus, through the above arrangement, the cooperation structure between the mirror 4 and the box body 1 can be made more firm.

[0053] As Figures 3 - 4 shown, in some embodiments of the present invention, one end of the support frame 5 may be connected to the box body 1, and the other end of the support frame 5 may be provided with a pivot seat 51. The in-vehicle head-up display system 100 may further include a pivot shaft 7. The pivot shaft 7 passes through the pivot seat 51 and is connected to the display member 6. Thus, the cooperation structure between the support frame 5 and the display member 6 can be made simpler and facilitate the assembly of the display member 6. Optionally, threaded portions may be respectively provided at both axial ends of the pivot shaft 7. The threaded portions pass through the pivot seat 51, and nuts may be used to threadedly cooperate with the threaded portions to limit the axial displacement of the pivot shaft 7.

[0054] In some embodiments of the present invention, at least one adjustment slot 52 is provided at one end of the support frame 5 connected to the box body 1. The adjustment slot 52 extends in the vertical direction. The support frame 5 is slidably engaged with the box body 1 through the adjustment slot 52 to further improve the applicability of the in-vehicle head-up display system 100. For example, in Figure 3 In the specific example shown, two adjustment slots 52 that are spaced apart and extend in the vertical direction are provided at one end of the support frame 5 connected to the box body 1. The support frame 5 can move up and down relative to the box body 1 through the adjustment slots 52. Thus, the position of the display member 6 in the up-and-down direction can be conveniently adjusted, which is convenient for the actual operation of the driver 200. When the driver 200 is relatively short and rotating the display member 6 still cannot ensure that the display image is in front of the driver 200, the support frame 5 can be pressed downwards, and the support frame 5 can drive the display member 6 to move downwards to a suitable position. When the driver 200 is relatively tall and rotating the display member 6 still cannot ensure that the display image is in front of the driver 200, the support frame 5 can be pulled upwards, and the support frame 5 can drive the display member 6 to move upwards to a suitable position. It can be understood that the adjustment slot 52 can also be one, three or more than three. Of course, one end of the support frame 5 can also be fixedly connected to the box body 1.

[0055] As Figure 4 shown, in some embodiments of the present invention, an assembly plate 621 can be provided at one end of the display member 6 close to the support frame 5. The in-vehicle head-up display system 100 can further include a pivot connection frame 8. The pivot connection frame 8 can be sleeved on the pivot shaft 7 and rotate synchronously with the pivot shaft 7. The assembly plate 621 can be connected to the pivot connection frame 8, thereby making the connection manner between the display member 6 and the pivot shaft 7 simpler.

[0056] For example, the assembly plate 621 can be formed as a plate-like structure, the pivot connection frame 8 can be formed as a cuboid, the assembly plate 621 can cooperate with one of the side walls of the pivot connection frame 8, and a square assembly slot 81 can also be defined on the side wall of the pivot connection frame 8. The assembly plate 621 can be arranged in the assembly slot 81 and connected to the pivot connection frame 8. Thus, through the above arrangement, the pivot connection frame 8 can rotate synchronously with the pivot shaft 7, and the display member 6 and the pivot connection frame 8 can form a surface-to-surface cooperation, so that the cooperation between the display member 6 and the pivot shaft 7 can be more compact and firm.

[0057] In Figure 3In the specific embodiment shown, the display member 6 includes a display portion 61 and a mounting portion 62. The display portion 61 can be used to receive the light reflected by the mirror 4 and present a display image. The mounting portion 62 is provided along the outer periphery of the display portion 61 to fix the display portion 61. Among them, an assembly plate 621 is provided at one end of the mounting portion 62 close to the support frame 5, and the assembly plate 621 and the mounting portion 62 are integrally injection molded. Thus, through the above settings, the overall structure of the display member 6 can be made simpler, and the assembly efficiency of the in-vehicle head-up display system 100 can be improved.

[0058] As Figure 3 shown, in some embodiments of the present invention, the box body 1 may include: a main body 11, an upper cover 12 and a lower cover 13. An installation space with an open top may be provided inside the main body 11. The image production optical machine 3 may be provided in the installation space. The upper cover 12 may be covered above the installation space. The lower cover 13 may cooperate with the bottom of the main body 11 to define an assembly space for the PCB board 2. Thus, through the above settings, the structural design of the box body 1 can be made more reasonable. The image production optical machine 3 and the PCB board 2 are respectively placed in independent spaces, which can ensure the normal operation of the image production optical machine 3 and the PCB board 2.

[0059] Optionally, the upper cover 12 may be assembled with the main body 11 by means of screw connection, or the upper cover 12 may also be pivotally connected to the main body 11 through a rotating shaft. Optionally, the lower cover 13 may also be assembled with the main body 11 by means of screw connection or bolt connection.

[0060] Of course, it can be understood that the box body 1 may also only include the main body 11 and the upper cover 12. The main body 11 has an installation space with an open top, and the upper cover 12 is covered on the main body 11. The image production optical machine 3 and the PCB board 2 may be placed in the installation space at the same time and arranged at intervals. Thus, the use requirements of the in-vehicle head-up display system 100 can also be met.

[0061] As Figure 6 shown, in some embodiments of the present invention, an electrical connection port 131 may be provided on the side wall of the lower cover 13. The PCB board 2 is provided in the lower cover 13 and may be disposed opposite to the electrical connection port 131. Thus, it is convenient for the PCB board 2 to be electrically connected to the display control system. Specifically, the PCB board 2 may be provided in the lower cover 13 and electrically connected to the electrical connection port 131. The display control system may be electrically connected to the electrical connection port 131 through a wiring harness. Thus, an electrical connection can be formed among the PCB board 2, the wiring harness and the display control system, and the display control system can transmit display data to the PCB board 2.

[0062] Optionally, positioning holes 21 may be provided on the PCB board 2, and positioning posts 111 extending into the positioning holes 21 may be provided at the bottom of the main body 11, whereby the assembly method between the PCB boards 2 can be made simpler. Moreover, arranging the PCB board 2 at the bottom of the main body 11 can shorten the assembly distance between the PCB board 2 and the image production optical machine 3, facilitating the electrical connection between the PCB board 2 and the image production optical machine 3. It should be noted that the fixing method of the PCB board 2 is not limited to this. For example, the PCB board 2 can also be connected to the bottom of the main body 11 by means of screw connection. The PCB board 2 can also be fixed on the inner side wall of the bottom plate and can be set according to actual usage requirements, and the present invention does not make specific limitations thereto.

[0063] In some embodiments of the present invention, the support frame 5 and the mirror 4 may be respectively arranged on opposite side walls of the main body 11. For example, as Figures 1 - 2 shown, the support frame 5 may be arranged on the front side wall of the main body 11, and the mirror 4 may be arranged on the rear side wall of the main body 11. Thus, the light projected by the image production optical machine 3 can be smoothly reflected onto the display member 6 after being reflected by the mirror 4, improving the display effect of the display member 6.

[0064] In some embodiments of the present invention, the main body 11 and the support frame 5 may be formed as an integral part. For example, the main body 11 and the support frame 5 may be formed as an integrally injection-molded part. Thus, through the above arrangement, the overall structure of the in-vehicle head-up display system 100 can be made simpler, and the assembly efficiency of the in-vehicle head-up display system 100 can be improved.

[0065] According to some embodiments of the present invention, the in-vehicle head-up display system 100 may further include a positioning mechanism (not shown in the figure), and the positioning mechanism may cooperate with the display member 6 and the support frame 5 respectively to keep the display member 6 at a set rotation angle, thereby preventing the rotation angle of the display member 6 from changing when the vehicle jolts during driving, thus facilitating the actual operation of the driver 200.

[0066] Optionally, the positioning mechanism is a ratchet and pawl mechanism, which may include a ratchet and a pawl. The ratchet is provided on the display member 6 and rotates synchronously with the display member 6. The display member 6 is pivotally connected to the support frame 5 through a pivot shaft 7. The pawl is movably provided on the pivot shaft 7 and meshes or disengages with the ratchet. For example, the display member 6 may be pivotally connected to the support frame 5 through the pivot shaft 7. The ratchet may be provided on the display member 6 and rotate synchronously with the display member 6. The pawl may be provided on the pivot shaft 7 and mesh with the ratchet. The pawl may move in the axial direction of the pivot shaft 7. When the display member 6 rotates in a direction away from the mirror 4, the ratchet teeth slide with the ratchet to enable the ratchet to rotate. When the display member 6 rotates to a set position, the ratchet teeth abut against the ratchet to prevent the display member 6 from reversing. When the display member 6 needs to reverse, the axial position of the pawl on the pivot shaft 7 may be moved to separate the pawl from the ratchet teeth. Thus, through the above arrangement, the structural design of the positioning mechanism can be made simpler and the positioning more reliable.

[0074] The display member 6 is rotatably disposed on the support frame 5, and the display member 6 may be an optical reflection lens. Among them, the display member 6 includes a display portion 61 and a mounting portion 62. The display portion 61 may be used to receive the light reflected by the mirror 4 and form a display image. The mounting portion 62 is disposed on the outer peripheral edge of the display portion 61 to fix the display portion 61. One end of the mounting portion 62 close to the support frame 5 is provided with an assembly plate 621, and the assembly plate 621 and the mounting portion 62 are formed as an integrally injection molded part.

[0075] One end of the support frame 5 may be connected to the front side wall of the box body 1. The other end of the support frame 5 may be provided with a pivot seat 51. The pivot shaft 7 passes through the pivot seat 51. The pivot connection frame 8 is formed in a cuboid shape and is sleeved on the pivot shaft 7 to rotate synchronously with the pivot shaft 7. The assembly plate 621 is formed in a plate-like structure. A square assembly groove 81 may be defined on one side wall of the pivot connection frame 8. The assembly plate 621 may be placed in the assembly groove 81 and connected to the pivot connection frame 8. Two adjustment grooves 52 which are spaced apart and extend in the vertical direction are provided at the end of the support frame 5 where it is connected to the box body 1. The support frame 5 can move up and down relative to the box body 1 through the adjustment grooves 52. Thus, the position of the display member 6 in the up and down direction can be conveniently adjusted, which is convenient for the actual operation of the driver 200.

[0076] Specifically, the display control system can transmit the display data corresponding to the display information to the PCB board 2 through a flexible cable. The PCB board 2 can parse, process, convert, and transmit the display data to the image production optical machine 3. The image production optical machine 3 can parse and process the data from the PCB board 2 and synthesize a display image corresponding to the display control system. The image production optical machine 3 can include a light regulator and a light-emitting display screen. The light regulator can magnify the display image. The light-emitting display screen is located at the end of the image emission end 3a. The display image can be imaged on the light-emitting display screen. The image emission end 3a can project the parsed image onto the reflector 4 through light. The reflector 4 can reflect the light to the display member 6, and after being reflected and refracted by the display member 6, a projected virtual image is formed directly in front of the driver 200. The driver 200 can see the projected virtual image through the display member 6. The display member 6 can perform distortion correction on the display image, preventing the display image from being distorted, thereby improving the display effect of the display member 6. Moreover, the optical reflection lens has a good light transmission effect. The part of the optical reflection lens other than the display image can be formed as a transparent member, thereby preventing the display member 6 from blocking the vehicle's windshield and further improving driving safety.

[0077] Since the display member 6 is rotatably provided on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to actual usage requirements, thereby adapting to different drivers 200 and different driving habits, and the display image can be adjusted to directly in front of the driver 200. When driving the vehicle, the driver 200 can obtain the display information of the display control system through the display image without switching the line of sight, which not only brings great convenience to the actual operation of the driver 200 but also improves the driving safety of the vehicle.

[0078] When the driver 200 is relatively short and rotating the display member 6 still cannot ensure that the display image is directly in front of the driver 200, the support frame 5 can be pressed downward, and the support frame 5 can drive the display member 6 to move downward to a suitable position. When the driver 200 is relatively tall and rotating the display member 6 still cannot ensure that the display image is directly in front of the driver 200, the support frame 5 can be pulled upward, and the support frame 5 can drive the display member 6 to move upward to a suitable position.

[0079] Thus, through the above settings, by arranging the image production optical machine 3, the reflector 4, and the display member 6, the overall structure of the in-vehicle head-up display system 100 can be made simpler and the operation more convenient. By arranging the display member 6 to be rotatably provided on the support frame 5, the rotation angle between the display member 6 and the support frame 5 can be adjusted according to actual usage requirements. Thus, the display image can be located directly in front of the driver 200. When driving the vehicle, the driver 200 can obtain the display information of the display control system through the display image without switching the line of sight, which not only brings great convenience to the actual operation of the driver 200 but also improves the driving safety of the vehicle. By providing the adjustment groove 52 on the support frame 5, the support frame 5 can move up and down relative to the box body 1 through the adjustment groove 52. Thus, the position of the display member 6 in the up-down direction can be conveniently adjusted, which is convenient for the actual operation of the driver 200.
