Description

Technical Field

[0001] This application relates to the field of vehicle HUD technology, and in particular to a head-up display system and an MPV vehicle. Background Technology

[0002] A head-up display (HUD) system projects driving information onto the vehicle's windshield, allowing the driver to access information without looking down, thereby improving driving safety and convenience.

[0003] In the prior art, there are structures that fix the head-up display system to the instrument panel beam of a car using mounting brackets. This type of mounting structure uses the instrument panel beam as the load-bearing base and is suitable for vehicles that support the head-up display system through the instrument panel beam. However, this type of mounting structure is not applicable to MPV vehicles that need to fix the head-up display system to the front bulkhead.

[0004] Existing technologies also include head-up display systems that centrally arrange the optical mechanism, image adjustment mechanism, and PCB main control components within the housing. This results in a large size of the head-up display system along the height direction. For MPV models where the height space in the front panel area is limited, such head-up display systems are difficult to install and are prone to causing first-order mode degradation, leading to jitter in the projected image. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a head-up display system and an MPV vehicle to solve the problem that the positioning method and height space occupation of existing head-up display systems cannot be adapted to MPVs.

[0006] The above-mentioned objectives of this application are mainly achieved through the following technical solutions: A head-up display system for a vehicle, the head-up display system being fixedly mounted on the front bulkhead of the vehicle, the front bulkhead having a side section, and a top section and a middle section fixedly connected to the side section, the head-up display system comprising: The housing includes a main body and a cantilever connected to each other; the main body is disposed between the top section and the dashboard of the vehicle and is fixed to the top section; the cantilever extends from the main body in a direction away from the dashboard to one side of the side section and extends out of the front bulkhead; the cantilever is fixedly connected to the side section. The first and second reflecting mirrors are both located within the main body. An imaging unit is disposed within the cantilever section and is used to emit an image beam toward the second reflector; the image beam is reflected sequentially by the second reflector and the first reflector and then directed toward the windshield of the vehicle.

[0007] In an optional embodiment, both the first and second reflectors are freeform mirrors, and the first and second reflectors are respectively arranged obliquely within the main body.

[0008] In an optional embodiment, the main body is connected to the top section by a plurality of spaced-apart fixing parts, and the cantilever is connected to the side section by a plurality of spaced-apart fixing parts.

[0009] In an optional embodiment, a reinforcing sheet metal is provided between the plurality of fixing parts and the housing, and the fixing parts are fixing bolts, rivets and / or snap-fit ​​parts.

[0010] In an optional embodiment, the middle section is arranged on the side of the top section away from the main body, and the side section is arranged on the side of the cantilever portion, and the top section, the middle section, and the side section enclose a water channel space.

[0011] In an optional embodiment, the water channel space is provided with a plurality of spaced reinforcing beams, which are fixedly connected to the top section, the middle section and the side section respectively, and the reinforcing beams are provided with drainage holes.

[0012] In an optional embodiment, the main body is provided with a dust cover that covers the first reflector and the second reflector, and the image beam reflected by the first reflector passes through the dust cover and is directed toward the windshield of the vehicle.

[0013] In an optional embodiment, the dust cover is recessed within the main body and is arranged in an arc shape. The dust cover is provided with two arc-shaped water baffles arranged at relatively intervals. Drainage grooves are provided on the arc-shaped water baffles, and the drainage grooves are located at the lowest point of the dust cover.

[0014] In an optional embodiment, the housing is mounted obliquely to the front bulkhead, and a threading space is formed between the main body, the cantilever, and the top section.

[0015] Based on the same inventive concept, this application also provides an MPV vehicle that includes the head-up display system as described above.

[0016] Compared with the prior art, the advantages of this application are: The head-up display system of this application is used to be fixedly installed on the front bulkhead of the vehicle. The front bulkhead has a side section, and a top section and a middle section fixedly connected to the side section. The head-up display system includes: a housing, a first reflector, a second reflector, and an imaging unit. The housing includes a main body and a cantilever section connected to each other. The main body is disposed between the top section and the dashboard of the vehicle and is fixed to the top section. The cantilever section extends from the main body section away from the dashboard to one side of the side section and extends out of the front bulkhead. The cantilever section is fixedly connected to the side section. The first reflector and the second reflector are both disposed within the main body section. The imaging unit is disposed within the cantilever section and is used to emit an image beam toward the second reflector. The image beam is reflected sequentially by the second reflector and the first reflector and then directed toward the windshield of the vehicle.

[0017] The head-up display system is fixedly installed on the front bulkhead of the vehicle. The main body of the housing is located between the top section of the front bulkhead and the vehicle's dashboard, and is fixed to the top section. Because the main body is directly fixed to the top section of the front bulkhead, the head-up display system can be installed using the front bulkhead as a load-bearing base. This adapts to the installation requirements of MPV models where the head-up display system is fixed to the front bulkhead, overcoming the defect of existing technologies that use instrument beam-based mounting structures as load-bearing bases and are therefore unsuitable for front bulkhead installation.

[0018] In this head-up display system, the cantilever portion of the housing extends from the main body in a direction away from the dashboard and extends beyond the front bulkhead. The imaging unit is located within the cantilever portion, while the first and second reflectors are located within the main body. During operation, the imaging unit within the cantilever portion emits an image beam toward the second reflector. The image beam is reflected sequentially by the second and first reflectors before being projected onto the vehicle's windshield. Because the imaging unit is located within the cantilever portion extending beyond the front bulkhead, and the first and second reflectors for reflecting the image beam are located within the main body, the imaging unit does not need to be positioned between the front bulkhead and the dashboard. This significantly reduces the height space requirement between the front bulkhead and the dashboard, allowing for a reduction in the height dimension of the head-up display system. This enables the stable and reliable installation of a large-size head-up display system in MPV vehicles, overcoming the shortcomings of existing automotive head-up display systems where the optomechanical mechanism, image adjustment mechanism, and PCB main control components are concentrated within the housing, resulting in a large height dimension and difficulty in placement within the front bulkhead area.

[0019] In addition, the cantilever is fixedly connected to the side section, so that the cantilever extending out of the front panel is supported by the side section, avoiding vibration or sagging of the cantilever due to its large overhang length. This ensures the stability of the imaging unit arranged in the cantilever, which is conducive to the stable emission of the image beam and improves the stability of the projected image.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0023] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, Figure 1 A side view of the head-up display system 1 provided in an embodiment of this application; Figure 2A top view of the head-up display system 1 provided in the embodiments of this application; Figure 4 Appendix provided for the embodiments of this application Figure 2 Sectional view at point BB; Figure 5 This is a schematic diagram of the structure of the head-up display system 1 after installation, as provided in the embodiments of this application. Figure 6 This is a cross-sectional view of the head-up display system 1 provided in the embodiments of this application after installation.

[0024] A head-up display system for a vehicle, the head-up display system 1 being fixedly installed on the front bulkhead of the vehicle, the front bulkhead having a side section 201, and a top section 202 and a middle section 203 fixedly connected to the side section 201, the head-up display system 1 including a housing 102, a first reflector 105, a second reflector 106, and an imaging unit 107, wherein: The housing 102 includes a main body 103 and a cantilever 104 connected to each other; the main body 103 and the cantilever 104 together enclose a receiving space for accommodating optical elements. The main body 103 is disposed between the top section 202 and the instrument panel 6 of the vehicle, and is fixed to the top section 202; the cantilever 104 extends from the main body 103 away from the instrument panel 6 to one side of the side section 201, and extends out of the front bulkhead; the cantilever 104 is fixedly connected to the side section 201. like Figure 5 and Figure 6 As shown, the main body 103 is located in the space between the top section 202 of the front bulkhead and the instrument panel 6. The side of the main body 103 facing the top section 202 is fixed to the top section 202 by a fixed connection, so that the head-up display system 1 can be installed on the front bulkhead as a supporting base, which is suitable for the installation requirements of fixing the head-up display system 1 to the front bulkhead of MPV models.

[0025] The cantilever portion 104 extends from the main body 103 in a direction away from the instrument panel 6, extends to one side of the side section 201, and extends out of the front bulkhead. The cantilever portion 104 is fixedly connected to the side section 201, so that the cantilever portion 104 extending out of the front bulkhead is supported by the side section 201. In this way, with the main body 103 fixed to the top section 202 and the cantilever portion 104 fixed to the side section 201, the head-up display system 1 can be stably mounted on the front bulkhead, while the cantilever portion 104 extending out of the front bulkhead is supported by the side section 201, preventing the cantilever portion 104 from vibrating or sagging due to its large overhang length.

[0026] The first reflector 105 and the second reflector 106 are both disposed within the main body 103; the imaging unit 107 is disposed within the cantilever 104 and is used to emit an image beam 115 toward the second reflector 106; the image beam 115 is reflected sequentially by the second reflector 106 and the first reflector 105 and then directed toward the windshield 5 of the vehicle.

[0027] The first reflector 105 and the second reflector 106 are both disposed within the main body 103, and the imaging unit 107 is disposed within the cantilever 104. The imaging unit 107 is used to generate an image beam 115, and the light outlet of the imaging unit 107 is positioned facing the second reflector 106. During operation, the imaging unit 107 emits the image beam 115 towards the second reflector 106. The image beam 115 first reaches the second reflector 106, is reflected by the second reflector 106, reaches the first reflector 105, and is then reflected by the first reflector 105 before being projected onto the windshield 5 of the vehicle, thereby forming a display image on the windshield 5 for the driver to view. The imaging unit 107 can be an image generation unit or other device used to generate the image beam 115; this embodiment does not limit the specific type of the imaging unit 107.

[0028] like Figure 2 , Figure 4 As shown, the imaging unit 107 is housed within the cantilever portion 104 extending from the front bulkhead, while the first reflecting mirror 105 and the second reflecting mirror 106 for reflecting the image beam 115 are housed within the main body portion 103. The imaging unit 107 does not need to be positioned between the front bulkhead and the instrument panel 6, thus reducing the required height space between them. This allows for a reduction in the height dimension of the head-up display system 1, making it possible to install a large-size head-up display system 1 on an MPV. Simultaneously, the cantilever portion 104 is fixedly connected to the side section 201, ensuring the stability of the imaging unit 107's arrangement and facilitating the stable emission of the image beam 115, thereby improving the stability of the projected image.

[0029] In an optional embodiment, the head-up display system 1 of this application is used to be fixedly installed on the front bulkhead of the vehicle. The front bulkhead has a side section 201, and a top section 202 and a middle section 203 fixedly connected to the side section 201. The head-up display system 1 includes: a housing 102, a first reflector 105, a second reflector 106, and an imaging unit 107. The housing 102 includes a main body 103 and a cantilever 104 connected to each other. The main body 103 is disposed between the top section 202 and the instrument panel 6 of the vehicle, and is fixed to the top section 201. Section 202; the cantilever portion 104 extends from the main body portion 103 in a direction away from the instrument panel 6 to one side of the side section 201 and extends out of the front bulkhead; the cantilever portion 104 is fixedly connected to the side section 201; the first reflector 105 and the second reflector 106 are both disposed in the main body portion 103; the imaging unit 107 is disposed in the cantilever portion 104 and is used to emit an image beam 115 toward the second reflector 106; the image beam 115 is reflected sequentially by the second reflector 106 and the first reflector 105 and then directed toward the windshield 5 of the vehicle.

[0030] The head-up display system 1 is fixedly installed on the front bulkhead of the vehicle. The main body 103 of the housing 102 is located between the top section 202 of the front bulkhead and the instrument panel 6 of the vehicle, and is fixed to the top section 202. Since the main body 103 is directly fixed to the top section 202 of the front bulkhead, the head-up display system 1 can be installed using the front bulkhead as a load-bearing base, thus adapting to the installation requirements of MPV models where the head-up display system 1 is fixed to the front bulkhead. This overcomes the defect of the existing technology where the installation structure based on the instrument beam is not suitable for front bulkhead installation because it uses the instrument beam as a load-bearing base.

[0031] In this head-up display system 1, the cantilever portion 104 of the housing 102 extends from the main body 103 in a direction away from the instrument panel 6 and extends out of the front bulkhead. The imaging unit 107 is disposed within the cantilever portion 104, and the first reflector 105 and the second reflector 106 are disposed within the main body 103. During operation, the imaging unit 107 disposed within the cantilever portion 104 emits an image beam 115 toward the second reflector 106. The image beam 115 is reflected sequentially by the second reflector 106 and the first reflector 105 and then directed toward the windshield 5 of the vehicle. Since the imaging unit 107 is arranged within the cantilever portion 104 extending from the front bulkhead, and the first reflector 105 and the second reflector 106 for reflecting the image beam 115 are arranged within the main body portion 103, the imaging unit 107 does not need to be arranged between the front bulkhead and the instrument panel 6, thereby significantly reducing the height space requirement between the front bulkhead and the instrument panel 6. This allows the size of the head-up display system 1 in the height direction to be reduced, enabling the large-size head-up display system 1 to be stably and reliably installed in MPV models. This overcomes the shortcomings of the prior art vehicle head-up display system 1, which has a large height dimension and is difficult to install in the front bulkhead area due to the concentrated arrangement of the optomechanical mechanism, image adjustment mechanism and PCB main control components within the housing 102.

[0032] In addition, the cantilever 104 is fixedly connected to the side section 201, so that the cantilever 104 extending out of the front panel is supported by the side section 201, avoiding vibration or sagging of the cantilever 104 due to its large overhang length, ensuring the stability of the arrangement of the imaging unit 107 in the cantilever 104, which is conducive to the stable emission of the image beam 115 and improves the stability of the projected image.

[0033] like Figure 2 , Figure 4 As shown, in an optional embodiment, the first reflector 105 and the second reflector 106 are both freeform mirrors, and the first reflector 105 and the second reflector 106 are respectively arranged obliquely within the main body 103.

[0034] Furthermore, the freeform mirror's surface is freeform, meaning the curvature of the mirror can be independently designed along different directions and positions. This allows for aberration correction of the image beam 115, eliminating or reducing distortions, field curvatures, and other aberrations generated during the propagation of the image beam 115, expanding the display field of view, and ensuring the clarity and realism of large-size displayed images. The first reflecting mirror 105 and the second reflecting mirror 106 are respectively tilted within the main body 103. The second reflecting mirror 106 receives the image beam 115 emitted by the imaging unit 107 and reflects it back to the first reflecting mirror 105, which then reflects the image beam 115 back to the windshield 5. By rationally setting the tilt angles of the first reflecting mirror 105 and the second reflecting mirror 106, the propagation path of the image beam 115 can be adjusted, allowing the imaging unit 107 to be positioned within the cantilever portion 104 extending from the front bulkhead. Simultaneously, this reduces the height dimension of the head-up display system 1 in the front bulkhead area, further reducing height space requirements.

[0035] like Figure 2 , Figure 3 , Figure 5 As shown, Figure 3 Appendix provided for the embodiments of this application Figure 2 A cross-sectional view at point AA; in an optional embodiment, the main body 103 is connected to the top section 202 by a plurality of spaced-apart fixing parts 116, and the cantilever 104 is connected to the side section 201 by a plurality of spaced-apart fixing parts 116.

[0036] Furthermore, multiple fixing parts 116 are arranged at intervals along the circumference of the main body 103, forming a multi-point fixed connection between the main body 103 and the top section 202. The connection force is evenly distributed along the main body 103, avoiding local stress concentration. Similarly, multiple fixing parts 116 are arranged at intervals along the cantilever section 104, forming a multi-point fixed connection between the cantilever section 104 and the side section 201. In this way, a reliable fixed connection is formed between the main body 103 and the top section 202, and between the cantilever section 104 and the side section 201. Even if one of the fixing parts 116 fails due to vibration, aging, or other reasons, the remaining fixing parts 116 can still maintain the connection between the head-up display system 1 and the front panel, improving the connection reliability and safety of the head-up display system 1 and preventing the head-up display system 1 from loosening or falling off due to single-point connection failure.

[0037] like Figure 2 , Figure 3 As shown, in an optional embodiment, a reinforcing sheet metal 113 is provided between the plurality of fixing parts 116 and the housing 102, and the fixing parts 116 are fixing bolts, rivets and / or snap-fits.

[0038] Furthermore, the reinforcing sheet metal 113, located between the fixing part 116 and the housing 102, enhances the structural rigidity of the fixing part 116, disperses the stress at the fixing part 116, and improves the first-order mode of the head-up display system 1 itself. Due to the large size and weight of the head-up display system 1, if its first-order mode is low, it is prone to resonance with vehicle body vibration during vehicle operation, leading to image jitter. By setting the reinforcing sheet metal 113 to improve the first-order mode of the head-up display system 1, the natural frequency of the head-up display system 1 can avoid the vibration frequency of the vehicle body, suppressing the vibration of the head-up display system 1 during operation, thereby suppressing image jitter and ensuring the stability of the displayed image. The fixing part 116 is connected using fixing bolts, riveting parts, and / or snap-fit ​​parts, providing flexible and diverse connection methods. Appropriate connection methods can be selected according to different assembly spaces and process requirements, improving assembly convenience and adaptability.

[0039] like Figure 5 , Figure 6 As shown, in an optional embodiment, the middle section 203 is arranged on the side of the top section 202 away from the main body 103, and the side section 201 is on the side away from the cantilever 104. The top section 202, the middle section 203, and the side section 201 enclose a water channel space 3.

[0040] Furthermore, the top section 202, the middle section 203, and the side section 201 are interconnected and enclosed to form a drainage channel space 3 through which water can flow and drain. During vehicle use, rainwater and other water flows downward along the windshield 5, and after flowing to the front bulkhead, it can enter the drainage channel space 3 formed by the top section 202, the middle section 203, and the side section 201, and flow and drain along the drainage channel space 3. This prevents water from accumulating at the front bulkhead or entering the interior of the head-up display system 1, protecting the optical components of the head-up display system 1 from water corrosion, and ensuring the normal operation of the head-up display system 1.

[0041] like Figure 5 , Figure 6 As shown, in an optional embodiment, the water channel space 3 is provided with a plurality of spaced reinforcing beams 4, which are fixedly connected to the top section 202, the middle section 203 and the side section 201 respectively, and the reinforcing beams 4 are provided with drainage holes.

[0042] Furthermore, the reinforcing beam 4 is fixedly connected to the top section 202, the middle section 203, and the side section 201 respectively, forming a structural reinforcement of the water channel space 3 and improving the vehicle body environmental mode of the water channel area. Since the head-up display system 1 is fixed to the front bulkhead, the vehicle body mode of the front bulkhead and the water channel area directly affects the vibration characteristics of the head-up display system 1. By setting the reinforcing beam 4 to improve the vehicle body environmental mode of the water channel area and match it with the mode of the head-up display system 1 itself, the resonance between the head-up display system 1 and the vehicle body can be effectively suppressed, further suppressing the jitter of the projected image. The reinforcing beam 4 is provided with drainage holes, so that the water flowing into the water channel space 3 can be smoothly discharged through the drainage holes, avoiding the accumulation of water in the water channel space 3.

[0043] like Figure 1 , Figure 2 As shown, in an optional embodiment, the main body 103 is provided with a dust cover 101, which covers the first reflector 105 and the second reflector 106, and the image beam 115 reflected by the first reflector 105 passes through the dust cover 101 and is directed toward the windshield 5 of the vehicle.

[0044] Furthermore, the dust cover 101 covers the first reflector 105 and the second reflector 106, forming a protective barrier on the outside of the first reflector 105 and the second reflector 106. This prevents dust, moisture, and other impurities from adhering to the mirror surfaces of the first reflector 105 and the second reflector 106, ensuring the cleanliness of the mirror surfaces. Mirror surface cleanliness is crucial for ensuring the reflection quality of the image beam 115. If dust or other impurities adhere to the mirror surface, the image beam 115 will scatter or lose energy during reflection, affecting the clarity of the displayed image. By protecting the mirror surfaces with the dust cover 101, the reflection quality of the image beam 115 can be guaranteed, thereby ensuring the clarity of the displayed image. At the same time, the dust cover 101 does not obstruct the image beam 115 reflected by the first reflector 105. The image beam 115 can pass through the dust cover 101 and reach the windshield 5, ensuring the integrity and brightness of the displayed image.

[0045] like Figure 1 , Figure 3 as well as Figure 5 , Figure 6 As shown, in an optional embodiment, the dust cover 101 is recessed within the main body 103, and the dust cover 101 is arranged in an arc shape. The dust cover 101 is provided with two arc-shaped water baffles 112 arranged at relatively intervals. The arc-shaped water baffles 112 are provided with drainage grooves 111, and the drainage grooves 111 are located at the lowest point of the dust cover 101.

[0046] Furthermore, the dust cover 101 is recessed within the main body 103, which reduces its occupancy in the height direction and further reduces the height dimension of the head-up display system 1. The dust cover 101 is arranged in an arc shape, allowing water to flow smoothly along its arc surface and preventing water from lingering on the surface. Two arc-shaped baffles 112 are arranged at intervals on the dust cover 101 to prevent water from entering the interior of the head-up display system 1 and thus preventing water from corroding the optical components. The arc-shaped baffles 112 have drainage channels 111 located at the lowest point of the dust cover 101, allowing water flowing onto the dust cover 101 to converge at the lowest point and drain through the drainage channels 111, preventing water residue on the dust cover 101 from affecting the display effect and improving the waterproof performance and practicality of the head-up display system 1.

[0047] like Figure 5 , Figure 6 As shown, in an optional embodiment, the housing 102 is obliquely mounted on the front bulkhead, and a threading space 114 is formed between the main body 103, the cantilever 104, and the top section 202.

[0048] Furthermore, the housing 102 is installed at an angle on the front bulkhead, so that the overall posture of the head-up display system 1 is adapted to the tilt angle of the windshield 5, ensuring that the image beam 115, after being reflected by the first reflector 105, can be projected onto the windshield 5 at a suitable angle, thereby ensuring the position and clarity of the displayed image. A wiring space 114 is formed between the main body 103, the cantilever 104, and the top section 202. This wiring space 114 is used for the wiring harness of the head-up display system 1 to pass through.
