Description

Technical Field

[0001] The present invention relates to the technical field of automobile front windshield design, and in particular to an adjustable automobile front windshield assembly and an adjustment method. Background Art

[0002] As cars become increasingly convenient and intelligent, the use of HUD (Head-Up Display) technology in automotive windshields is increasing. A head-up display system uses optical reflection and refraction to project driving information from the instrument panel onto the windshield. Its function is to project important driving information, such as speed and navigation, onto the windshield in front of the driver, allowing the driver to view these crucial information without having to look down or turn their head. As a display component, the angle of the windshield's wedge film and its mounting position are crucial.

[0003] Conventional technology involves pressing two sheets of glass together, with a wedge-shaped PVB film sandwiched between them. After curing under high temperature and pressure, the assembly is then fixed to the sheet metal using spacers. The glass glue then cures, sealing and bonding the two together. After assembly, the assembly is not adjustable, and the HUD effect can only be verified after the HUD optical engine is assembled and powered on.

[0004] However, due to fluctuations in the manufacturing and assembly of windshields, sheet metal, and optical and mechanical parts, as well as different heights and vision of different drivers, when driving on bumpy roads or adjusting seat height, double images may appear due to different viewing angles while the light path angle remains unchanged, which may affect the driver's observation of driving information and may pose a safety hazard.

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The embodiments of the present application provide an adjustable automobile front windshield assembly and an adjustment method, which can solve the problem in the prior art that due to fluctuations in the manufacturing of the front windshield, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and vision of different drivers, when driving on bumpy roads or adjusting the seat height, ghosting may occur due to different viewing angles while the light path angle remains unchanged, which may affect the driver's observation of driving information and may pose a safety hazard.

[0025] like Figure 1 and Figure 2 As shown, on the one hand, the present application provides an adjustable front bumper assembly for a vehicle, which includes: A mounting frame 1, which is used to be fixed on the body-in-white sheet metal 2; A front windshield 3, the angle of which is adjustable and arranged in the mounting frame 1; The adjustment mechanism 4 is connected to the windshield 3 and is used to adjust the position of the windshield 3 in the mounting frame 1 to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield 3 .

[0026] During installation of the adjustable windshield assembly, a mounting frame 1 is secured to a vehicle body in white sheet metal 2. A windshield glass 3 is positioned within the mounting frame 1 at an adjustable angle. An adjustment mechanism 4 is connected to the windshield glass 3 and is used to adjust the position of the windshield glass 3 within the mounting frame 1 to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield glass 3. The system determines whether ghosting occurs on the windshield glass 3. If so, the position of the windshield glass 3 within the mounting frame 1 is adjusted until the ghosting is eliminated. Since the angle of the windshield 3 is adjustable in the mounting frame 1, if there is a ghost image, the position of the windshield 3 in the mounting frame 1 is adjusted by the adjustment mechanism 4 until the ghost image is eliminated. By adjusting the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3, the distance between the virtual image and the real image displayed by the head-up display system on the windshield 3 can be adjusted to eliminate the ghost image. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing of the windshield, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and eyesight of different drivers, ghost images may appear due to different viewing angles when the light path angle remains unchanged on bumpy roads or when adjusting the seat height, which affects the driver's observation of driving information and may pose a safety hazard.

[0027] In this example, the mounting frame 1 is fixed to the body-in-white sheet metal 2 by glass glue 6 .

[0028] like Figure 1 and Figure 2 As shown, in some optional embodiments, a waterproof foam 5 is provided on the inner side of the mounting frame 1 , and the waterproof foam 5 is located between the windshield 3 and the mounting frame 1 .

[0029] In this embodiment, a waterproof foam 5 is provided on the inner side of the mounting frame 1. The waterproof foam 5 is located between the windshield 3 and the mounting frame 1, providing a waterproof sealing effect, and can preliminarily set the position of the windshield 3 in the mounting frame 1. Since the waterproof foam 5 is a flexible material, it does not affect the adjustment of the position of the windshield 3 in the mounting frame 1.

[0030] like Figure 1 and Figure 2 As shown, in some optional embodiments, the adjustment mechanism 4 includes: The motor mounting bracket 41 is fixedly arranged and located inside the body-in-white sheet metal 2; The adjusting motor 42 is arranged on the motor mounting bracket 41 and extends out of the body-in-white sheet metal 2 . The adjusting rod of the adjusting motor 42 is connected to the windshield 3 .

[0031] In this embodiment, the structure of the adjustment mechanism 4 is specifically described. The adjustment mechanism 4 includes a motor mounting frame 41 and an adjustment motor 42, wherein the motor mounting frame 41 is fixed and located on the inner side of the white body sheet metal 2, and the adjustment motor 42 is set on the motor mounting frame 41 and extends out of the white body sheet metal 2. The adjustment rod of the adjustment motor 42 is connected to the windshield 3, and the structure is simple and easy to adjust.

[0032] In this example, the adjusting rod of the adjusting motor 42 is connected to the lower part of the windshield 3 .

[0033] like Figure 1 and Figure 2 As shown, in some optional embodiments, the windshield 3 includes an inner glass 31 , an outer glass 32 and a PVB film 33 . The PVB film 33 is disposed between the inner glass 31 and the outer glass 32 , and the cross section of the PVB film 33 is wedge-shaped.

[0034] In this embodiment, the specific structure of the windshield 3 is described. The windshield 3 includes an inner glass 31, an outer glass 32 and a PVB film 33. The PVB film 33 is arranged between the inner glass 31 and the outer glass 32. The cross-section of the PVB film 33 is wedge-shaped, which facilitates the arrangement of the head-up display system.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, on the other hand, the present application also provides a method for adjusting an adjustable front bumper assembly of an automobile, which is implemented using the above-mentioned adjustable front bumper assembly of an automobile, and includes the following steps: Determining whether there is a double image displayed on the front windshield 3 by the head-up display system; If there is a ghost image, adjust the position of the windshield 3 in the mounting frame 1 until the ghost image disappears.

[0036] During installation of the adjustable windshield assembly, a mounting frame 1 is secured to a vehicle body in white sheet metal 2. A windshield glass 3 is positioned within the mounting frame 1 at an adjustable angle. An adjustment mechanism 4 is connected to the windshield glass 3 and is used to adjust the position of the windshield glass 3 within the mounting frame 1 to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield glass 3. The system determines whether ghosting occurs on the windshield glass 3. If so, the position of the windshield glass 3 within the mounting frame 1 is adjusted until the ghosting is eliminated. Since the angle of the windshield 3 is adjustable in the mounting frame 1, if there is a ghost image, the position of the windshield 3 in the mounting frame 1 is adjusted by the adjustment mechanism 4 until the ghost image is eliminated. By adjusting the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3, the distance between the virtual image and the real image displayed by the head-up display system on the windshield 3 can be adjusted to eliminate the ghost image. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing of the windshield, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and eyesight of different drivers, ghost images may appear due to different viewing angles when the light path angle remains unchanged on bumpy roads or when adjusting the seat height, which affects the driver's observation of driving information and may pose a safety hazard.

[0037] In some optional embodiments, adjusting the position of the windshield 3 in the mounting frame 1 includes: Determining the positional relationship between the virtual image and the real image displayed by the head-up display system on the windshield 3; According to the positional relationship between the virtual image and the real image, the windshield 3 is moved to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield 3 .

[0038] In this embodiment, the adjustment of the position of the windshield 3 in the mounting frame 1 specifically includes determining the positional relationship between the virtual image and the real image displayed on the windshield 3 by the head-up display system, and moving the windshield 3 according to the positional relationship between the virtual image and the real image to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield 3, so as to facilitate the adjustment of the distance between the virtual image and the real image displayed on the windshield 3 by the head-up display system to eliminate ghosting. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing of windshields, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and vision of different drivers, ghosting may occur due to different viewing angles when the light path angle remains unchanged on bumpy roads or when adjusting the seat height, thereby affecting the driver's observation of driving information and posing a potential safety hazard.

[0039] In some optional embodiments, the method of moving the windshield 3 according to the positional relationship between the virtual image and the real image to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield 3 includes: When the virtual image is above the real image, the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3 is increased; When the real image is above the virtual image, the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3 is reduced.

[0040] In this embodiment, the windshield 3 is moved according to the positional relationship between the virtual image and the real image to adjust the angle between the light emitted by the head-up display system and the inner surface of the windshield 3. Specifically, when the virtual image is above the real image, the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3 is increased, and when the real image is above the virtual image, the incident angle of the light emitted by the head-up display system on the inner surface of the windshield 3 is reduced. This facilitates adjustment of the distance between the virtual image and the real image displayed on the windshield 3 by the head-up display system to eliminate ghosting. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing and assembly of windshields, sheet metal, and optical and mechanical parts, as well as different heights and vision of different drivers, ghosting may occur due to different viewing angles when the light path angle remains unchanged on bumpy roads or when adjusting the seat height, which affects the driver's observation of driving information and may pose a safety hazard.

[0041] In some optional embodiments, the method of adjusting the position of the windshield 3 in the mounting frame 1 includes the following steps: Obtaining the set distance between the incident point on the outer surface of the PVB film 33 of the refracted light emitted by the head-up display system after passing through the inner glass 31 and the reverse extension line of the reflected light emitted by the head-up display system on the inner glass 31 when the virtual image and the real image displayed by the head-up display system on the windshield 3 overlap; According to the set distance, a set angle between the light emitted by the head-up display system and the inner surface of the windshield 3 is obtained.

[0042] In this embodiment, the method for adjusting the position of the windshield 3 in the mounting frame 1 specifically includes obtaining a set distance from the incident point of the refracted light emitted by the head-up display system after passing through the inner glass 31 when the virtual image and the real image displayed by the head-up display system on the windshield 3 coincide with each other to the reverse extension line of the reflected light emitted by the head-up display system on the inner glass 31. According to the set distance, a set angle between the light emitted by the head-up display system and the inner surface of the windshield 3 is obtained, that is, the windshield 3 can be adjusted by setting the angle, which can be used to quickly adjust the windshield 3. By obtaining a set angle between the light emitted by the head-up display system and the inner surface of the windshield 3, it is convenient to adjust the distance between the virtual image and the real image displayed by the head-up display system on the windshield 3 to eliminate ghosting. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing of the windshield, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and vision of different drivers, ghosting may occur due to different viewing angles when driving on bumpy roads or adjusting seat heights while the light path angle remains unchanged, which may affect the driver's observation of driving information and may pose a safety hazard.

[0043] In some optional embodiments, after obtaining the angle between the light emitted by the head-up display system and the inner surface of the windshield 3, the method further includes: Obtaining an angle difference from the current angle based on a set angle between the light emitted by the head-up display system and the inner surface of the windshield 3; According to the angle difference, the advancing distance of the regulating motor 42 is obtained.

[0044] In this embodiment, after obtaining the angle between the light emitted by the head-up display system and the inner surface of the windshield 3, it also includes obtaining the angle difference from the current angle based on the set angle between the light emitted by the head-up display system and the inner surface of the windshield 3, and obtaining the propulsion distance of the adjustment motor 42 based on the angle difference, that is, the windshield 3 can be adjusted by adjusting the propulsion distance of the motor 42, and the windshield 3 can be adjusted quickly, so that the distance between the virtual image and the real image displayed on the windshield 3 by the head-up display system is conveniently adjusted to eliminate ghosting. The adjustment process is simple, which solves the problem in the prior art that due to fluctuations in the manufacturing of the windshield, sheet metal, and optical and mechanical parts, and fluctuations in assembly, as well as different heights and eyesight of different drivers, ghosting may occur due to different viewing angles when the light path angle remains unchanged on bumpy roads or when adjusting the seat height, which affects the driver's observation of driving information and may pose a safety hazard.

[0045] In some optional embodiments, according to the formula: Obtaining the advancing distance of the regulating motor 42; in, The set distance is the distance between the incident point of the refracted light from the head-up display system after passing through the inner glass 31 on the outer side of the PVB film 33 and the reverse extension line of the reflected light from the head-up display system on the inner glass 31. is the distance from the incident point of the light emitted by the head-up display system on the inner glass 31 to the vertex of the PVB film 33, is the incident angle of the light emitted by the head-up display system onto the inner surface of the windshield 3, is the angle difference, To adjust the propulsion distance of the motor 42, is the refractive index of the PVB film 33, is the top angle of the PVB film 33 .

[0046] In this embodiment, according to the formula: Obtain the advancing distance of the regulating motor 42, wherein, The set distance is the distance between the incident point of the refracted light from the head-up display system after passing through the inner glass 31 on the outer side of the PVB film 33 and the reverse extension line of the reflected light from the head-up display system on the inner glass 31. is the distance from the incident point of the light emitted by the head-up display system on the inner glass 31 to the vertex of the PVB film 33, is the incident angle of the light emitted by the head-up display system onto the inner surface of the windshield 3, is the angle difference, To adjust the propulsion distance of the motor 42, is the refractive index of the PVB film 33, is the top angle of the PVB film 33. The propulsion distance of the adjustment motor 42 can be quickly obtained to adjust the windshield 3, conveniently adjusting the distance between the virtual image and the real image displayed on the windshield 3 by the head-up display system to eliminate ghosting. The adjustment process is simple, solving the problem in the prior art that due to fluctuations in the manufacturing and assembly of windshields, sheet metal, and optical and mechanical parts, as well as differences in height and vision of different drivers, ghosting may occur due to different viewing angles when adjusting seat height while the optical path angle remains unchanged on bumpy roads. This can affect the driver's ability to observe driving information and pose a potential safety hazard.

[0047] In this example, the geometric relationship is: For materials with less impurities, the angle relationship of light entering the PVB film 33 from the glass can be considered constant, which can be expressed by the refractive index: , combining the above two equations, we can get: The thrust is applied by adjusting the stroke of the motor 42 at the lower part of the electrically controlled windshield 3 to adjust the gap between the windshield 3 and the body-in-white sheet metal 2, thereby achieving the purpose of adjusting the HUD light path. The angle change of the PVB film 33 under the thrust of the adjusting motor 42 is , then the angle of incidence becomes , substituting into the above formula, we get: In this model, it can be approximately considered that the regulating motor 42 always advances perpendicularly to the lower surface of the PVB film 33, so the change in angle can be expressed as the advancing distance of the regulating motor 42, which is easier to measure. To express: , and finally concluded . It is the refraction angle of the light emitted by the head-up display system hitting the inner surface of the windshield 3.

[0048] In this case, the geometric relationship shows that The length change of Related, so and Correlation means that after determining any value, the other value can be obtained.

[0049] In summary, based on the actual situation, the stroke of the electric adjustment motor 42 at the bottom of the windshield 3 is adjusted to adjust the gap between the windshield 3 and the body-in-white sheet metal 2, thereby fine-tuning the installation angle of the windshield 3, offsetting differences (customer height, manufacturing deviations, etc.), and approaching the theoretical state of the HUD optical path, so that the distance between the main image and the secondary image is less than the human eye's recognition rate to achieve the purpose of eliminating ghosting.
