Description

Technical Field

[0001] This application relates to the technical field of vehicle-mounted products, and in particular to a head-up display device. Background Technology

[0002] A head-up display (HUD) is an image display technology used in vehicles. HUDs project vehicle speed, navigation routes, and other driving information onto the windshield in front of the driver, allowing the driver to see these information while observing the road ahead. However, if the position of the driving information displayed on the windshield is inappropriate, it can obstruct the driver's view. In such cases, the position of the driving information needs to be adjusted. However, due to road bumps, the adjusted position of the driving information can change due to vehicle vibrations, further obstructing the driver's view and creating a safety hazard. Summary of the Invention

[0003] Therefore, it is necessary to provide a head-up display device to address the safety hazards caused by changes in the position of driving information displayed on the windshield due to road bumps.

[0015] In one embodiment, the rotating assembly further includes a rotating handle, one end of the first rotating shaft is connected to the reflective assembly, and the other end of the first rotating shaft is connected to the rotating handle; or...

[0016] The rotating assembly also includes a drive motor, which is drivenly connected to the first rotating shaft.

Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] Please see Figure 1 and Figure 5 One embodiment of this application provides a head-up display device, including a first mounting base 110, a rotating assembly 200, a pressing assembly 300, and a reflective assembly 500. The first mounting base 110 is used to fix the head-up display device and has a first pressing surface 111. The rotating assembly 200 is rotatably disposed on the first mounting base 110. The pressing assembly 300 is movably disposed on the rotating assembly 200 and can reciprocate along the rotating assembly 200 toward the first pressing surface 111. The pressing assembly 300 is used to press against the first pressing surface 111. The reflective assembly 500 is connected to the rotating assembly 200 and can receive image light 700 and reflect the image light 700 to the windshield 600.

[0036] In the aforementioned head-up display device, the rotating component 200 can rotate on the first mounting base 110 to drive the reflector component 500 mounted on the rotating component 200 to rotate. The reflector component 500 can reflect the image light 700 to the target position, thereby forming an image for the driver to observe at the target position. The pressing component 300 can move on the rotating component 200 to press against the first pressing surface 111 of the first mounting base 110. Friction is generated between the pressing component 300 and the first pressing surface 111. The friction can provide damping for the rotation of the rotating component 200, preventing the reflector component 500 on the rotating component 200 from swinging arbitrarily, and ensuring the stability of the reflector component 500 when reflecting the image light 700. Compared with conventional technology, the aforementioned head-up display device can adjust the rotation angle of the reflector component 500 to adjust the position of the image. After adjustment, the pressing component can provide damping for the rotating component, preventing the reflector component 500 from swinging arbitrarily due to road bumps, thereby preventing changes in the image position from obstructing the driver's vision while driving and improving driving safety.

[0037] Furthermore, in some embodiments, the head-up display device also includes a light source assembly 400, which can emit image light 700 to the reflector assembly 500. After being reflected, the image light 700 is projected onto a target position such as the windshield 600 of a car, so that the driver can observe it.

[0038] Specifically, the image light 700 emitted by the light source component 400 contains driving information, including but not limited to vehicle speed, navigation route, remaining battery power or remaining gasoline, and remaining diesel.

[0039] As a supplement, when greater damping is required for the rotating assembly 200, the user adjusts the movement of the pressing assembly 300 and applies greater pressure to the first pressing surface 111 through the pressing assembly 300, thereby increasing the friction between the pressing assembly 300 and the first pressing surface 111 and thus increasing the damping of the rotating assembly 200 during rotation. When it is necessary to reduce the damping of the rotating assembly 200 during rotation, the user adjusts the pressing assembly 300 to move in the opposite direction and reduces the pressure applied to the first pressing surface 111, thereby reducing the friction between the pressing assembly 300 and the first pressing surface 111 and thus reducing the damping of the rotating assembly 200 during rotation, providing high adjustment flexibility. Furthermore, after the reflector assembly 500 is adjusted to a specified angle, the user can also position the reflector assembly 500 at a specified angle by further increasing the friction between the pressing assembly 300 and the first pressing surface 111, preventing the reflector assembly 500 from shaking when reflecting the image light 700.

[0040] Optionally, the rotating assembly 200 can be a component that can rotate on the first mounting base 110, such as a rotating shaft or a turntable; no specific limitation is made here.

[0041] Optionally, the first mounting base 110 may be plate-shaped or other shapes, without specific limitations.

[0042] Specifically, the first pressing surface 111 protrudes from the first mounting base 110, thereby ensuring the pressing effect between the first pressing surface 111 and the pressing component 300.

[0043] Furthermore, in the above embodiments, the rotating component can be rotated by a motor drive or by manual means, etc., without specific limitations.

[0044] Please see Figures 1 to 3 In one embodiment, the rotating component 200 includes a first rotating shaft 210, which is rotatably disposed on the first mounting base 110 and passes through the first pressing surface 111. The reflective component 500 is disposed on the first rotating shaft 210 and can rotate synchronously with the first rotating shaft 210. The side wall of the first rotating shaft 210 is provided with a first threaded portion. The pressing component 300 includes a first pressing nut 310, which is screwed to the first threaded portion and used to press against the first pressing surface 111.

[0045] The first rotating shaft 210 can rotate relative to the first mounting base 110, thereby driving the reflector assembly 500 to rotate. The first pressing nut 310 can be screwed into the first threaded part on the side wall of the first rotating shaft 210, so that the first pressing nut 310 can move along the axial direction of the first rotating shaft 210, thereby pressing the first pressing surface 111. Friction will be generated between the first pressing surface 111 and the first pressing nut 310. The friction will provide a certain damping for the rotation of the first rotating shaft 210, preventing the reflector assembly 500 on the first rotating shaft 210 from swinging randomly, and ensuring the stability of the reflector assembly 500 when reflecting the image light 700. This setting is low in implementation cost and reliable in effect.

[0046] Specifically, the first rotating shaft 210 passes through the first pressing nut 310 so that the first pressing nut 310 is screwed to the first threaded part on the side wall of the first rotating shaft 210. When the first pressing nut 310 rotates, it can drive itself to move along the axial direction of the first rotating shaft 210, thereby pressing against the first pressing surface 111. By rotating the first pressing nut 310, the pressure of the first pressing nut 310 on the first rotating shaft 210 can be adjusted, thereby adjusting the friction between the first pressing nut 310 and the first pressing surface 111, and then adjusting the damping when the first rotating shaft 210 rotates. The adjustment process is simple and highly flexible.

[0047] Please see Figures 1 to 3In one embodiment, the pressing assembly 300 further includes a first gasket 311, a first rotating shaft 210 passing through the first gasket 311, and the first gasket 311 being sandwiched between the first pressing nut 310 and the first pressing surface 111.

[0048] The first washer 311, sandwiched between the first pressing nut 310 and the first pressing surface 111, can not only increase the friction and improve the damping effect of the first rotating shaft 210 during rotation, but also prevent the first pressing nut 310 from excessively pressing the first pressing surface 111 and causing damage to the first pressing surface 111, thus improving its service life.

[0049] Specifically, in the above embodiment, one side of the first washer 311 generates friction with the first pressing nut 310, and the other side of the first washer 311 generates friction with the first pressing surface 111, thereby increasing the overall friction and improving the damping effect when the first rotating shaft 210 rotates.

[0050] Furthermore, at least two first washers 311 are provided, and all the first washers 311 are sandwiched between the first pressing nut 310 and the first pressing surface 111. The two adjacent first washers 311 can also generate friction between each other. In this way, by providing at least two first washers 311, the friction can be increased, thereby improving the damping effect of the first rotating shaft 210 when rotating.

[0051] Please see Figures 1 to 3 In one embodiment, the first mounting base 110 has a second pressing surface 112, the first pressing surface 111 and the second pressing surface 112 are disposed opposite to each other, the first rotating shaft 210 passes through the first pressing surface 111 and the second pressing surface 112, the pressing assembly 300 also includes a second pressing nut 320 and a second washer 321, the second pressing nut 320 is screwed to the first threaded portion, the first rotating shaft 210 passes through the second washer 321, and the second washer 321 is sandwiched between the second pressing nut 320 and the second pressing surface 112.

[0052] The second pressing nut 320 is screwed into the first threaded portion of the first rotating shaft 210 to press against the second washer 321, thereby pressing against the second pressing surface 112. Thus, the first pressing nut 310 and the second pressing nut 320 can simultaneously press against the first pressing surface 111 and the second pressing surface 112 of the first mounting base 110, thereby clamping the first mounting base 110 between the first pressing nut 310 and the second pressing nut 320. The first pressing nut 310 and the second pressing nut 320 respectively press against the first pressing surface 111 and the second pressing surface 112. Friction is generated between 12, thereby improving the damping effect of the first rotating shaft 210 during rotation, ensuring the stability of the reflector 500 when reflecting the image light 700, and preventing the reflector from swaying due to vibration when the vehicle is driving on bumpy roads. The second washer 321, which is sandwiched between the second pressing nut 320 and the second pressing surface 112, can not only increase the friction and improve the damping effect of the first rotating shaft 210 during rotation, but also prevent the second pressing nut 320 from excessively pressing the second pressing surface 112 and causing damage to the second pressing surface 112, thus improving its service life.

[0053] Furthermore, at least two second washers 321 are provided, and all the second washers 321 are sandwiched between the second pressing nut 320 and the second pressing surface 112. The two adjacent second washers 321 can also generate friction between each other. In this way, by providing at least two second washers 321, the friction can be increased, thereby improving the damping effect of the first rotating shaft 210 when rotating.

[0054] Please see Figures 1 to 3 In one embodiment, the head-up display device further includes a second mounting base 120 for fixing the head-up display device. The rotating assembly 200 includes a second rotating shaft 220, which is rotatably disposed on the second mounting base 120. The second rotating shaft 220 is coaxial with and spaced apart from the first rotating shaft 210. One end of the reflective assembly 500 is disposed on the first rotating shaft 210, and the other end of the reflective assembly 500 is disposed on the second rotating shaft 220.

[0055] The second rotating shaft 220 is rotatably mounted on the second mounting base 120 and is coaxial with and spaced apart from the first rotating shaft 210. The two ends of the reflective component 500 can be respectively mounted on the first rotating shaft 210 and the second rotating shaft 220, and rotate under the drive of the first rotating shaft 210 and the second rotating shaft 220. This arrangement can improve the stability of the reflective component 500 when rotating and also strengthen the installation strength of the reflective component 500.

[0056] Furthermore, the second mounting base 120 and the first mounting base 110 are symmetrically arranged with respect to the reflector assembly 500. The head-up display device is fixed to the vehicle body through the first mounting base 110 and the second mounting base 120. Correspondingly, the arrangement of the second rotating shaft 220 is similar to that of the first rotating shaft 210, and will not be described again here.

[0057] Please see Figures 1 to 3 In one embodiment, the second mounting base 120 has a third pressing surface 121, the pressing assembly 300 includes a third pressing nut 330, the side wall of the second rotating shaft 220 is provided with a second threaded portion, the third pressing nut 330 is screwed to the second threaded portion and used to press against the third pressing surface 121.

[0058] The second rotating shaft 220 can rotate relative to the second mounting base 120, thereby driving the reflector assembly 500 to rotate. The third pressing nut 330 can be screwed into the second threaded part on the side wall of the second rotating shaft 220, so that the third pressing nut 330 can move along the axial direction of the second rotating shaft 220, thereby pressing against the third pressing surface 121. Friction will be generated between the third pressing surface 121 and the third pressing nut 330. The friction will provide a certain damping for the rotation of the second rotating shaft 220, preventing the reflector assembly 500 on the second rotating shaft 220 from swinging randomly due to vehicle shaking, and ensuring the stability of the reflector assembly 500 when reflecting the image light 700. This setting is low in implementation cost and reliable in effect.

[0059] Furthermore, the pressing assembly 300 also includes a third gasket 331, through which the second rotating shaft 220 passes, and the third gasket 331 presses against the third pressing nut 330 and the third pressing surface 121.

[0060] The third washer 331, sandwiched between the third pressing nut 330 and the third pressing surface 121, can not only increase the friction and improve the damping effect of the second rotating shaft 220 during rotation, but also prevent the third pressing nut 330 from excessively pressing the third pressing surface 121 and causing damage to the third pressing surface 121, thus improving its service life.

[0061] Specifically, the first gasket 311, the second gasket 321, and the third gasket 331 are all rigid gaskets to generate sufficient friction.

[0062] Please see Figures 1 to 3 In one embodiment, the rotating assembly 200 further includes a rotating handle 230, one end of the first rotating shaft 210 is connected to the reflective assembly 500, and the other end of the first rotating shaft 210 is connected to the rotating handle 230.

[0063] With this configuration, the user can rotate the first rotating shaft 210 by rotating the rotating handle 230, thereby adjusting the angle of the reflector 500 and adjusting the position of the image on the windshield 600 to prevent the image on the windshield 600 from obstructing the driver's view while driving. The adjustment process is convenient.

[0064] In another embodiment, the rotating assembly 200 further includes a drive motor, which is drivenly connected to the first rotating shaft 210.

[0065] Please see Figures 1 to 4 In one embodiment, the reflective assembly 500 includes a mounting plate 510 and a reflector 520. The mounting plate 510 is connected to the rotating assembly 200. The mounting plate 510 includes a mounting protrusion 514, which is an elastic structure. The mounting plate 510 is connected to the reflector 520 through the mounting protrusion 514. The reflector 520 is used to receive the image light 700 and reflect the image light 700 to the target position.

[0066] Thus, when the rotating component 200 drives the mounting plate 510 to rotate, the direction of the reflector 520 can be adjusted, thereby adjusting the reflection direction of the image light 700, preventing the image light 700 on the windshield 600 from obstructing the driver's vision while driving, and improving driving safety; the mounting protrusion 514 is an elastic structure that can buffer the reflector 520, preventing the image position of the reflector 520 from shaking and changing due to vehicle bumps, and improving driving safety.

[0067] In addition, the reflector 520 is connected to the mounting plate 510 through the mounting protrusion 514, rather than in full contact, in order to reduce the stress on the reflector 520 and prevent the reflector 520 from causing imaging distortion or even breakage due to stress.

[0068] Specifically, the mirror 520 is connected to the mounting protrusion 514 by applying glue to the mounting protrusion 514.

[0069] Please see Figures 1 to 4 In one embodiment, there are multiple mounting protrusions 514, which are arranged in an array on the mounting plate 510.

[0070] By providing multiple mounting protrusions 514, the assembly strength between the mounting plate 510 and the reflector 520 is improved. See also... Figures 1 to 4 In one embodiment, the mounting plate 510 has a first surface 511 and a second surface 512 opposite to each other, and a reflector 520 is disposed on the second surface 512. The reflector 520 is used to reflect the image light 700 to the windshield 600.

[0071] Please see Figure 4In one embodiment, the reflector 520 has a reflecting surface 521 and a mounting surface 522. The reflecting surface 521 is concave and arranged opposite to the light source assembly 400, and the mounting surface 522 is disposed on the second surface 512.

[0072] Mounting surface 522 is located on the second surface 512 of mounting plate 510 to facilitate the installation of reflector 520 and mounting plate 510. Reflecting surface 521 is concave to facilitate the convergence of light, improve the projection clarity of image light 700, and avoid light shadows or image blurring on windshield 600.

[0073] Furthermore, the assembly plate 510 is a curved panel with a bent surface. The first surface 511 is the convex surface of the curved panel, and the second surface 512 is the concave surface of the curved panel. Correspondingly, the reflector 520 is also a curved mirror. The shape of the curved mirror matches the shape of the second surface 512. The concave mirror is positioned towards the light source assembly 400 to facilitate the convergence of light, improve the clarity of the image, and avoid light and shadow or image blurring.

[0074] Furthermore, the two opposite ends of the curved panel in the width direction are respectively connected to the first rotating shaft 210 and the second rotating shaft 220 to drive the curved panel to rotate.

[0075] Specifically, the reflector 520 is a free-form glass curved mirror, which is made from a plane mirror through processes such as hot bending and tempering. Its radius of curvature can be adjusted by process parameters such as the curvature of the hot bending mold, the hot bending temperature, the hot bending time, and the pressure of the hot bending. The reflective surface 521 of the free-form glass curved mirror is vacuum-deposited with an optical film layer by a magnetron sputtering machine or an evaporation machine, so that the reflective surface 521 has the function of reflecting image light. The image light 700 emitted by the light source component 400 can be reflected by the reflective surface 521, and finally imaged on the windshield 600 of the vehicle. In this embodiment, the free-form glass curved mirror replaces the traditional injection-molded mirror, which is low in cost and reliable in process.

[0076] In one embodiment, the reflector 520 is provided with an explosion-proof film.

[0077] By installing an explosion-proof film on the reflector 520, the reflector 520 can be prevented from breaking due to excessive force, thus improving the strength of the reflector 520.

[0078] Furthermore, the mounting surface 522 of the free-form glass mirror is sprayed with black explosion-proof ink to form an explosion-proof film, which increases the explosion-proof performance of the free-form glass mirror and prevents it from breaking due to excessive force.

[0079] In one embodiment, both ends of the mounting plate 510 are provided with weight-reducing grooves 513 to reduce the overall weight of the head-up display device.

[0080] Please see Figure 3 In one embodiment, the assembly plate 510 is provided with a reinforcing grid 530 to improve the strength and stability of the assembly plate 510.

[0081] Please see Figure 3 Specifically, the reinforcing grille 530 is honeycomb-shaped and is located on the first surface 511.

[0082] The honeycomb-shaped reinforcing grille 530 can improve the strength of the mounting plate 510, prevent the mounting plate 510 from cracking due to vibration or collision during vehicle operation, and thus improve the overall strength of the head-up display device.

[0083] Furthermore, the grille 530 is reinforced with a hexagonal grille to provide sufficient support strength for the mounting plate 510.
