Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and more specifically, to a multi-module PHUD display device structure. Background Technology

[0002] Existing automotive HUD display systems primarily employ motion projection structures, projecting information onto the windshield via reflective optical elements. These solutions are typically complex, bulky, and costly, and require significant installation space and high optical calibration precision.

[0003] To improve structural compactness and ease of assembly, some vehicle models have begun to adopt integrated or screen-type PHUD display devices. PHUD display devices include display modules with built-in screens that display images projected onto the vehicle's windshield. However, existing PHUD display devices generally suffer from the following problems: First, the exposed area of ​​the display module in existing PHUD display devices is relatively large, resulting in many unusable areas besides the display screen being exposed. These areas are easily affected by ambient light, causing glare and affecting the clarity and display effect of the image. Second, the display module in PHUD display devices is usually equipped with a heat sink. Since heat sinks are typically made of aluminum or other materials with good thermal conductivity, their smooth surfaces have high reflectivity and are prone to glare. Existing display modules do not have corresponding shielding structures for the heat sink, allowing some ambient light to be reflected off the heat sink surface and interfere with the light emitted from the display screen, severely affecting the display effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a multi-module PHUD display device structure to solve the problems existing in the background art.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A multi-module PHUD display device structure includes: a mounting bracket including a shielding portion; multiple display modules, spaced apart and mounted on the mounting bracket, each display module including a display panel and a heat sink disposed on the back of the display panel, the side of the display panel away from the heat sink having a display screen; a first shielding portion installed in the interval between adjacent display modules; a second shielding portion having bent portions formed at both ends, the two bent portions extending to both ends of the shielding portion respectively; wherein the shielding portion and the second shielding portion together form a closed display window, through which each display screen is covered.

[0007] In the above scheme, multiple independent display modules are configured for easy maintenance. The display screen displays images, and a heat sink is located on the back of the display panel to dissipate heat from the entire display module, ensuring its normal operation. The second shield, through bends on both sides, closes the gap between itself and the blocking part, forming a closed display window. This window covers all the display screens, providing reliable light shielding to prevent interference from ambient light. Simultaneously, the first shield blocks the gap between adjacent display modules, preventing the heat sink on the back of the display module from being exposed through the gap, thus avoiding glare interference. This ensures that only the effective display area (the area where the display screen is located) is exposed within the display window. By setting up the blocking part, the first shield, and the second shield, while ensuring effective light shielding of the display screen, the exposed area of ​​the ineffective display module is significantly reduced, minimizing glare caused by ambient light interference and effectively improving display clarity and effect.

[0008] In one example of this utility model, both the shielding part and the second shield are arc-shaped.

[0009] In the above solution, by setting the shielding part and the second shielding part to an arc shape, the shape and structure of the front dashboard of the vehicle are matched, resulting in a high degree of appearance integration and easy installation.

[0010] In one example of this invention, the two sides of the first mask extend to the surface of the adjacent display module to block the non-display area at the edge of the display panel.

[0011] In the above solution, the two sides of the first mask can block the non-display areas on both sides of the display panel to further reduce the exposed area of ​​the invalid area on the display panel, so as to avoid the exposure of reflection and improve the display clarity.

[0012] In one example of this utility model, the end face of the second shield is provided with a clearance groove that cooperates with the first shield.

[0013] In the above scheme, the clearance groove is set correspondingly to the first shield, and is used to make way for the first shield when the second shield is installed. By setting the clearance groove, the end face of the second shield can fit more tightly with the display panel, preventing light leakage. At the same time, it can also make the overall structure more compact.

[0014] In one example of this utility model, the display module further includes a base, on which a mounting groove is formed to mate with the display panel, and the heat sink is mounted on the side of the base away from the mounting groove.

[0015] In the above solution, the base is mounted on the mounting bracket, and the display panel is mounted in the mounting slot, with the base providing reliable mounting for the display panel.

[0016] In one example of this utility model, the base is provided with connecting blocks on both sides, the connecting blocks are provided with connecting holes, and the mounting bracket includes a mounting part, the mounting part being provided with fixing holes that cooperate with the connecting holes.

[0017] In the above solution, the connecting holes and fixing holes are correspondingly set, allowing the base to be installed on the mounting bracket using fasteners, forming a stable and rigid connection. This prevents the display module from shifting due to vehicle vibration and avoids display deviation. Furthermore, each display module is installed individually via its base, making assembly and disassembly simpler and facilitating individual maintenance, thus improving convenience.

[0018] In one example of this utility model, the mounting part is provided with a protruding positioning block, and the connecting block is provided with a positioning hole that cooperates with the positioning block.

[0019] In the above solution, by setting matching positioning blocks and positioning holes, the base and the mounting bracket can be quickly positioned, which facilitates the installation of the base and the mounting bracket.

[0020] In one example of this utility model, the mounting part is provided with a card interface, and the first cover is provided with a buckle that cooperates with the card interface.

[0021] In the above solution, by setting matching buckles and clips, the first cover and the mounting bracket can be detachably connected for easy replacement. At the same time, the clips and clips allow for quick positioning of the first cover during installation, simplifying the installation of the first cover and the mounting bracket and making the operation more convenient.

[0022] In one example of this invention, the heat sink includes a plurality of spaced-apart heat dissipation fins.

[0023] In the above scheme, the heat dissipation fins are used to increase the contact area between the heat sink and the air, so as to improve the heat dissipation speed and efficiency of the heat sink.

[0024] In one example of this utility model, the end face of the heat dissipation fins is provided with a plurality of grooves at intervals.

[0025] In the above solution, by setting grooves, the contact area between the heat dissipation fins and the air can be further increased, thereby improving the heat dissipation speed and efficiency.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention comprises a shielding part, a first shield, and a second shield. The shielding part and the second shield together form a closed display window that covers the display screens of multiple display modules, ensuring reliable light shielding to prevent interference from ambient light. Simultaneously, the first shield blocks the gaps between adjacent display modules, preventing the heat sinks on the back of the display modules from being exposed through the gaps, thus avoiding glare interference and ensuring only the effective display area (the area where the display screen is located) is exposed. By incorporating the shielding part, the first shield, and the second shield, while ensuring effective light shielding, the exposed area of ​​the ineffective display modules is significantly reduced, thereby minimizing glare caused by ambient light interference and effectively improving display clarity and effect. Furthermore, this invention has fewer components, a simple and compact structure, effectively saving manufacturing costs, making it more economical and conducive to widespread use.

Detailed Implementation

[0038] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0039] Please refer to Figures 1 to 9 A multi-module PHUD display device structure includes a mounting bracket 1, display modules 2, a first shield 3, and a second shield 4. The mounting bracket 1 includes a shielding part 11. Multiple display modules 2 are provided and are installed on the mounting bracket 1 at intervals. Each display module 2 includes a display panel 21 and a heat sink 22 located on the back of the display panel 21. A display screen 211 is provided on the side of the display panel 21 away from the heat sink 22. The first shield 3 is installed in the interval between adjacent display modules 2. The two ends of the second shield 4 are bent to form bending parts 41, and the two bending parts 41 extend to the two ends of the shielding part 11 respectively. The shielding part 11 and the second shield 4 together form a closed display window 5, through which each display screen 211 is covered.

[0040] There are three display modules 2, which are set independently to facilitate maintenance. Correspondingly, there are two first masks 3 to block the gap between adjacent display modules 2.

[0041] Specifically, the mounting bracket 1 is installed inside the vehicle's dashboard to securely mount the device within the vehicle. The display screen 211 is used to display images, and a heat sink 22 is located on the back of the display panel 21 to dissipate heat from the entire display module 2, ensuring its normal operation. Figure 1As shown, the second shield 4, through the bent portions 41 on both sides, closes the gap between itself and the shielding portion 11, thereby forming a closed display window 5. The display window 5 covers all the display screens 211, dividing the visible area and non-display area into distinct zones. The display window 5 formed by the shielding portion 11 and the second shield 4 can reliably shield each display screen 211 from ambient light interference, ensuring display quality. Simultaneously, the first shield 3 can shield the gap between adjacent display modules 2, preventing the heat sink 22 on the back of the display module 2 and the mounting structures on both sides from being exposed. This ensures that only the effective display area (i.e., the area where the display screen 211 is located) is exposed within the display window 5. By setting the shielding portion 11, the first shield 3, and the second shield 4, while ensuring the shielding effect on the display screen 211, the exposed area of ​​the ineffective area of ​​the display module 2 can be significantly reduced, thereby reducing reflections caused by ambient light interference and effectively improving display clarity and effect.

[0042] It should be noted that if the gap between the display modules 2 is not blocked, on the one hand, the heat sink 22 may be exposed through the gap, causing glare interference; on the other hand, even if the heat sink 22 is not directly exposed through the gap, the glare it generates may still be reflected back to the top of the display module 2 through the gap, thereby interfering with the light emitted by the display screen 211 and affecting the display effect. This embodiment, by setting a first shield 3 in the gap between the display modules 2, can effectively avoid the above-mentioned glare interference, thereby ensuring the display effect.

[0043] Understandably, the surfaces of both the first mask 3 and the second mask 4 are matte-finished, which can effectively reduce the reflectivity of light, thereby further suppressing ambient light reflection and avoiding affecting the display effect.

[0044] Preferably, both the shielding part 11 and the second shield 4 are arc-shaped. By setting the shielding part 11 and the second shield 4 to an arc shape, the design structure of the vehicle's front dashboard is matched, resulting in a high degree of integration between the vehicle's interior and exterior, and facilitating the installation of this device. Accordingly, according to Figure 1 In the indicated direction, the three display modules 2 are arranged according to the shape of the blocking part 11 and the second mask 4, so that the blocking part 11 blocks the upper side of the display screen 211, while the second mask 4 blocks the lower side of the display screen 211. Together with the bent parts 41 on both sides, the display screen 211 is surrounded inside the display window 5 formed by the blocking part 11 and the second mask 4.

[0045] Please refer to Figure 1The two sides of the first mask 3 extend to the surface of the adjacent display module 2 to block the non-display area at the edge of the display panel 21. By extending the two sides of the first mask 3 to a portion of the display module 2, the non-display area on both sides of the display screen 211 on the display panel 21 is blocked, thereby further reducing the exposed area of ​​the invalid area on the display panel 21, avoiding the occurrence of exposed reflection, and improving display clarity.

[0046] Please refer to Figure 2 The end face of the second shield 4 is provided with a clearance groove 42 that mates with the first shield 3. The clearance groove 42 is correspondingly provided with the first shield 3 and is used to allow clearance for the first shield 3 when the second shield 4 is installed. By providing the clearance groove 42, the end face of the second shield 4 can fit more tightly with the display panel 21, preventing gaps that could lead to light leakage and effectively ensuring the light-blocking effect. At the same time, it can also make the overall structure more compact.

[0047] Please refer to Figures 4 to 7 The display module 2 includes a base 23 with a mounting slot 231 that mates with the display panel 21. A heat sink 22 is mounted on the bottom of the base 23, which is mounted on a mounting bracket 1. The display panel 21 is mounted in the mounting slot 231. By setting the base 23, a reliable mounting is provided for the display panel 21, ensuring that the display panel 21 is securely installed.

[0048] Furthermore, the base 23 has connecting blocks 232 on both sides, and connecting holes 2321 on the connecting blocks 232. The mounting bracket 1 includes a mounting part 12, and a fixing hole 13 corresponding to the connecting hole 2321 is provided on the mounting part 12.

[0049] Each base 23 has four connecting holes 2321, and the mounting part 12 has four holes. The two middle mounting parts 12 have four fixing holes 13 to support the installation of two adjacent display modules 2. The connecting holes 2321 and fixing holes 13 are correspondingly arranged, and the base 23 can be installed on the mounting bracket 1 with fasteners to form a stable rigid connection, preventing the display module 2 from shifting due to vehicle vibration and avoiding display deviation. In addition, each display module 2 is installed individually through the base 23, making disassembly and assembly easier and facilitating individual maintenance, thus improving convenience.

[0050] Preferably, both the connecting hole 2321 and the fixing hole 13 are threaded holes, and the base 23 is fixedly connected to the mounting part 12 by bolts. Alternatively, other fasteners can be used for connection.

[0051] Preferably, the mounting bracket 1 is made of metal or reinforced plastic to ensure sufficient rigidity and to ensure that it can adapt to the installation and use requirements in the vehicle environment.

[0052] Please refer to Figure 6 and Figure 7 The mounting part 12 is provided with a protruding positioning block 14, and the connecting blocks 232 on both sides of the base 23 are provided with positioning holes 2322 that cooperate with the positioning block 14. By setting the cooperating positioning block 14 and positioning hole 2322, the base 23 and the mounting bracket 1 can be quickly positioned, which facilitates the installation of the base 23 and the mounting bracket 1 and simplifies the installation process.

[0053] Please refer to Figure 1 The mounting section 12 is equipped with a card interface, and the first cover 3 is equipped with a buckle (not specifically shown in the figure) that cooperates with the card interface. By setting the cooperating buckle and card interface, the first cover 3 and the mounting bracket 1 can be detachably connected for easy replacement. At the same time, the setting of the card interface and buckle can realize the quick positioning of the first cover 3 during installation, simplifying the installation work of the first cover 3 and the mounting bracket 1, making the installation operation more convenient.

[0054] Please refer to Figure 8 and Figure 9 The radiator 22 includes a plurality of spaced heat dissipation fins 221, which are used to increase the contact area between the radiator 22 and the air, so as to improve the heat dissipation speed and heat dissipation efficiency of the radiator 22.

[0055] Furthermore, such as Figure 9 As shown, multiple grooves 222 are provided at intervals on the end face of the heat dissipation fins 221. By setting the grooves 222, the contact area between the heat dissipation fins 221 and the air can be further increased, thereby improving the heat dissipation speed and efficiency.

[0056] In this embodiment, the shielding part 11 and the second shield 4 form a closed display window 5. The display window 5 covers the display screens 211 of the multiple display modules 2, ensuring reliable light shielding of the display screens 211 to prevent interference from ambient light. Simultaneously, the first shield 3 can block the gap between adjacent display modules 2, preventing the heat sink 22 on the back of the display module 2 and the mounting structures on both sides from being exposed, thus only exposing the effective display area (i.e., the area where the display screen 211 is located). By setting the shielding part 11, the first shield 3, and the second shield 4, while ensuring the light shielding effect on the display screen 211, the exposed area of ​​the ineffective areas of the display modules 2 can be significantly reduced, thereby reducing reflections caused by ambient light interference. Compared with existing PHUD display devices, this effectively improves display clarity and effect, and offers higher reliability.
