[0039] The combined head-up display system provided by the present utility model. The combined head-up display system provided by this application realizes the simultaneous display of two virtual images, namely a far-field virtual image and a near-field virtual image, through innovative structural design and optical path layout. Specifically, this application utilizes the first TFT display component 1 and the second TFT display component 2 to emit light respectively, and reflects the light through the lens assembly and the windshield 5, and finally forms an enlarged long-distance virtual image and a near-field virtual image in front of the driver's eyes.

[0041] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0043] Embodiment 1 of the combined head-up display system of the present utility model

[0044] Please refer to Figure 1 , the combined head-up display system of the present utility model includes:

[0045] The first TFT display component 1 and the second TFT display component 2 are used to emit light respectively;

[0046] The lens assembly is used to reflect and guide the light emitted by the first TFT display component 1. The lens assembly can accurately control the propagation path of the light, ensuring the accurate and clear position of the virtual image on the windshield 5. This not only improves the driver's observation comfort, but also avoids visual interference caused by improper virtual image position. In addition, through the reflection and guidance of the lens assembly, the light can be made more concentrated, enhancing the brightness and contrast of the virtual image, making it clearly visible even in strong light environments;

[0047] The windshield 5 is used to reflect the light emitted by the first TFT display component 1 and the second TFT display component 2 and form a virtual image for the driver to observe; the combined head-up display system provided by the present application realizes the simultaneous display of two virtual images in the far field and the near field through innovative structural design and optical path layout. Specifically, the present application uses the first TFT display component 1 and the second TFT display component 2 to emit light respectively, and reflects the light through the lens component and the windshield 5, and finally forms an enlarged long-distance virtual image and a near-field virtual image in front of the driver's eyes. This design method not only enriches the driving information received by the driver, but also improves the driver's perception ability of the long-distance road conditions through the enlarged effect of the far-field virtual image, thereby enhancing driving safety.

[0048] Furthermore, the light emitted by the first TFT display component 1 is reflected by the second reflection lens 102 and then reflected by the windshield 5 into the human eye to form an enlarged long-distance virtual image; the light emitted by the second TFT display component 2 is directly reflected by the windshield 5 into the human eye to form a near-field virtual image. By different optical path designs, the separate display of the far-field and near-field virtual images is realized, so that the two virtual images do not interfere with each other, are clearer and more accurate. At the same time, this design method can also adjust the size and position of the virtual image according to different needs to improve the driver's observation experience. In addition, for the enlarged effect of the far-field virtual image, the driver can see the distant objects more clearly and improve the perception ability of the road conditions; the display requirements of the far-field and near-field virtual images are different, and different optical path designs can meet these requirements. For the far-field virtual image, the reflection of the second reflection lens 102 is required to achieve the enlarged effect, so that the driver can see the distant objects more clearly, while for the near-field virtual image, the direct reflection by the windshield 5 can meet the display requirements. Such a design can avoid the interference between the two virtual images and improve the clarity and accuracy of the display.

[0049] Furthermore, as Figure 1 shown, the lens component includes a first reflection lens 101 and a second reflection lens 102. The first reflection lens 101 and the second reflection lens 102 are used to realize the primary and secondary reflections of light to adjust the propagation path of light; the combination of the first reflection lens 101 and the second reflection lens 102 can more flexibly adjust the propagation path of light to adapt to different vehicle structures and installation positions. At the same time, the intensity of light can be enhanced through multiple reflections, and the brightness and contrast of the virtual image can be improved.

[0050] Furthermore, as Figure 1As shown, the first reflection lens 101 is located diagonally above the first TFT display component 1, and the second reflection lens 102 is located on the side of the first TFT display component 1. A reasonable layout of the lens positions can maximize the use of the in-vehicle space while ensuring the optimal light propagation path. The first reflection lens 101 located diagonally above can avoid direct conflict with the driver's line of sight and improve the comfort of observation. The second reflection lens 102 located on the side can better cooperate with the first TFT display component 1 to achieve accurate light reflection. In addition, this layout can also reduce light loss and improve the brightness and clarity of the virtual image.

[0051] Embodiment II of the combined head-up display system of the present utility model

[0052] Furthermore, in the combined head-up display system of the present utility model, as Figures 2 - 5 shown, a protective structure is provided between the first TFT display component 1 and the second TFT display component 2. The protective structure can effectively protect the first TFT display component 1 and the second TFT display component 2 from the influence of external factors such as collision, vibration, dust, etc. This can not only extend the service life of the display components but also ensure the stability and reliability of the system. In addition, the protective structure can also play a role in heat insulation and sound insulation, reducing the interference of the external environment on the display components and improving the display effect.

[0053] Furthermore, as Figures 2 - 5 shown, the protective structure includes a first protective shell 3. At the bottom of the inner cavity of the first protective shell 3, a first mounting seat 301 and a second mounting seat 302 are installed. The second reflection lens 102 is installed on the first mounting seat 301, and the first TFT display component 1 is installed on the second mounting seat 302. The first mounting seat 301 is used for supporting the second reflection lens 102, and the second mounting seat 302 is used for supporting the first TFT display component 1.

[0054] Furthermore, as Figure 4 and Figure 5 shown, a support plate 303 is also installed in the first protective shell 3. On the side of the support plate 303 close to the first TFT display component 1, a third mounting seat 304 is installed. The first reflection lens 101 is installed on the third mounting seat 304, and the third mounting seat 304 is used for supporting the first reflection lens 101.

[0055] Furthermore, the second TFT display component 2 is also installed on the third mounting seat 304, and the third mounting seat 304 is also used for supporting the second TFT display component 2.

[0056] Embodiment III of the combined head-up display system of the present utility model

[0057] Furthermore, in the combined head-up display system of the present utility model, as Figures 2 - 4As shown, a protective glass 4 is embedded in the top of the first protective shell 3. A second protective shell 305 is provided on the outer surface of the first protective shell 3. An opening 306 corresponding to the protective glass 4 is formed in the top of the second protective shell 305. The opening 306 is used to improve the protection effect. The double protection structure can provide more comprehensive protection for the internal display component and the reflecting lens. The protective glass 4 can block the intrusion of external factors such as dust and moisture, and at the same time can also play a role in resisting impact, protecting the internal components from damage.

[0058] Furthermore, as Figures 2 - 3 shown, a mounting seat is provided on the top of the first protective shell 3. The windshield 5 is arranged on the mounting seat. A through hole for the mounting seat to pass through is also formed in the top of the second protective shell 305. The design of the mounting seat and the through hole can facilitate the installation and fixation of the windshield 5 and improve the overall stability of the system.
