Description

Technical Field

[0001] The utility model relates to the technical field of display anti-shake, in particular to an anti-shake structure of a head-up display of an automobile. Background Art

[0002] With the rapid advancement of automotive technology, head-up display technology has become an indispensable part of modern car interiors, aiming to enhance the driver's safety and convenience by directly projecting key driving information such as speed, navigation instructions and vehicle status on the front windshield. With the growing market demand, customers have put forward higher requirements for the display effect of head-up displays, especially the expectation of obtaining image display with a larger field of view so that more information can be obtained without frequently shifting the line of sight during driving.

[0003] To meet this demand, the size of the reflective curved mirrors used in head-up display systems has also expanded. However, this technological advancement has also brought new challenges. When a vehicle is driving on an uneven or continuously bumpy road, the large-sized curved mirror is prone to shaking due to its high physical inertia and sensitivity to vibration. The shaking of the curved mirror not only reduces the readability of the information, but also may distract the driver's attention, thus posing a potential threat to driving safety, and significantly reduces the customer's overall user experience. Utility Model Content

[0004] The utility model aims to provide an anti-shake structure for a head-up display of an automobile. By arranging a reinforcing plate on the reflector, the overall strength of the reflector can be effectively enhanced to resist external impact and vibration, thereby avoiding the shaking of the reflector.

[0005] A vehicle head-up display anti-shake structure comprises a reflector and a reinforcement plate, wherein the reflector is arc-shaped and has a first surface and a second surface opposite to each other, wherein the second surface is located on a side of the reflector close to the arc center, the reinforcement plate is attached to the first surface and extends along the length direction of the first surface, and a protrusion structure is provided on a side of the reinforcement plate away from the first surface.

[0006] In the above technical solution, the mirror is designed in an arc shape, which helps to better focus and reflect the light from the projection unit of the head-up display, enabling the image to be clearly projected into the driver's forward field of view. The arc-shaped reflecting surface can also reduce light scattering to a certain extent, improving the contrast and brightness of the image. Setting a reinforcing plate on the first surface of the mirror can effectively enhance the overall strength of the mirror, resist external impacts and vibrations, and thus effectively reduce the phenomenon of the mirror shaking. A convex structure is provided on the side of the reinforcing plate facing away from the first surface, and these convex structures can reduce the local stress concentration caused by vibration by dispersing stress, thereby protecting the mirror from damage. Through the close combination of the reinforcing plate and the mirror, the overall strength and stability of the mirror are significantly improved, enabling the mirror to effectively resist the vibrations and impacts during vehicle driving.

[0007] Further, the convex structure includes an annular convex and a plurality of block-shaped convexes, and the block-shaped convexes are located within the area surrounded by the annular convex.

[0008] In the above technical solution, the combined design of the annular convex and the block-shaped convex provides more shock-absorbing points for the reinforcing plate. When the vehicle encounters vibrations or bumps during driving, these convexes can more effectively disperse and absorb the vibration energy, reducing the amplitude of vibrations transmitted to the mirror, thereby further improving the anti-shake performance.

[0009] Further, the block-shaped convexes are arranged along the length direction of the reinforcing plate.

[0010] In the above technical solution, the arrangement of the block-shaped convexes along the length direction of the reinforcing plate helps to disperse the vibration energy from vehicle driving to each block-shaped convex, thereby reducing the impact and vibration on the mirror and improving the anti-shake effect.

[0011] Further, through holes are provided between adjacent two block-shaped convexes.

[0012] In the above technical solution, when subjected to external impacts or vibrations, the design of the through holes can reduce the rigid connection between the block-shaped convexes, enabling the stress to be more easily dispersed in multiple directions, helping to reduce the risk of damage caused by stress concentration, and improving the overall durability of the anti-shake structure.

[0013] Further, an adhesive layer is provided on the side of the reinforcing plate facing the first surface.

[0014] In the above technical solution, as a connection method between the reinforcing plate and the mirror, the adhesive layer can provide strong adhesion, ensuring that the reinforcing plate is firmly adhered to the first surface of the mirror. This stable connection method can resist various vibrations and impacts during vehicle driving, prevent the reinforcing plate from loosening or falling off, and thus ensure the stability and reliability of the mirror.

[0015] Further, connecting portions are provided at both ends of the first surface. The connecting portions extend in a direction perpendicular to the first surface, and at least one reinforcing rib is connected between the connecting portions and the first surface.

[0016] In the above technical solution, the design of the connecting portions enables the mirror to be more firmly connected to the vehicle. They provide stable support points for the mirror and are tightly connected to the first surface through the reinforcing ribs, thus forming a solid overall structure. This enhanced connection strength and stability ensure that the mirror can work stably during vehicle driving without being affected by vibration and impact.

[0017] Further, a mounting portion is provided on a side of the connecting portion facing away from the reinforcing rib.

[0018] In the above technical solution, the design of the mounting portion makes the installation process of the mirror more simple and rapid. Installers can quickly fix the mirror to other structures on the vehicle through the mounting portion without a complex adjustment and calibration process.

[0019] Further, positioning notches that cooperate with the reinforcing ribs are provided at both ends of the reinforcing plate.

[0020] In the above technical solution, the design of the positioning notches enables the reinforcing plate to be quickly and accurately connected to the first surface without a complex adjustment and calibration process, thus simplifying the installation process.

[0021] Further, a rotating portion connected to an external transmission mechanism is provided at the lower end of the mirror.

[0022] In the above technical solution, the fixed display position may not maintain the best visibility in all cases. By designing the rotating portion and connecting it to the external transmission mechanism, the driver can adjust the display position of the image projected by the mirror on the windshield according to the actual situation.

[0023] Further, the reinforcing plate is made of metal.

[0024] In the above technical solution, the metal material is known for its high strength and durability, which enables the reinforcing plate to effectively resist vibrations, impacts, and stresses generated during vehicle driving. The metal reinforcing plate can ensure that the mirror remains stable under various harsh conditions, thereby extending the service life of the head-up display.

[0025] Compared with the prior art, the beneficial effects of the present utility model are:

[0026] 1. A reinforcing plate is provided and connected to the first surface of the mirror, effectively enhancing the overall strength of the mirror, resisting external impacts and vibrations, thereby avoiding mirror jitter.

[0027] 2. On the side of the reinforcing plate facing away from the first surface, there are convex structures. These convex structures can more effectively disperse the force from vehicle vibrations, prevent the reinforcing plate from deforming or being damaged due to excessive single-point stress, and thus affect the stability of the mirror.

[0034] Hereinafter, the anti-shake structure of the head-up display for automobiles of the present invention will be further described in detail with reference to specific embodiments and the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0035] Please refer to Figure 1 , in a preferred embodiment, the anti-shake structure of the head-up display for automobiles of the present invention includes a mirror 1 and a reinforcing plate 2. The mirror 1 is arc-shaped, the mirror 1 has opposite first surface 101 and second surface 102, the second surface 102 is located on the side of the mirror 1 close to the arc center, the reinforcing plate 2 is attached to the first surface 101 and extends along the length direction of the first surface 101, and a convex structure 201 is provided on the side of the reinforcing plate 2 facing away from the first surface 101.

[0036] In the above technical solution, the reflector 1 is designed in an arc shape, which helps to better focus and reflect the light from the projection unit of the head-up display, enabling the image to be clearly projected into the driver's forward field of view. The arc-shaped reflecting surface can also reduce light scattering to a certain extent, improving the contrast and brightness of the image. Setting the reinforcing plate 2 on the first surface 101 of the reflector 1 can effectively enhance the overall strength of the reflector 1, resist external impacts and vibrations, thereby effectively reducing the phenomenon of jitter of the reflector 1. The side of the reinforcing plate 2 facing away from the first surface 101 is provided with raised structures 201, and these raised structures 201 can reduce the local stress concentration caused by vibration by dispersing stress, thereby protecting the reflector 1 from damage. Through the close combination of the reinforcing plate 2 and the reflector 1, the present utility model significantly improves the overall strength and stability of the reflector 1, enabling the reflector 1 to effectively resist vibrations and impacts during vehicle driving.

[0037] Specifically, the raised structure 201 includes an annular protrusion 2011 and a plurality of block-shaped protrusions 2012, and the block-shaped protrusions 2012 are located within the area surrounded by the annular protrusion 2011. The combined design of the annular protrusion 2011 and the block-shaped protrusions 2012 provides more shock-absorbing points for the reinforcing plate 2. When the vehicle encounters vibrations or bumps during driving, these protrusions 201 can more effectively disperse and absorb the vibration energy, reducing the amplitude of vibrations transmitted to the reflector 1, thereby further improving the anti-shake performance.

[0038] Please refer to Figure 2 , in an embodiment, the block-shaped protrusions 2012 are arranged along the length direction of the reinforcing plate 2. The arrangement of the block-shaped protrusions 2012 along the length direction of the reinforcing plate 2 means that the block-shaped protrusions 2012 are dispersed on the reinforcing plate 2, which helps to disperse the vibration energy from vehicle driving to each block-shaped protrusion 2012, thereby reducing the impact and vibration on the reflector 1 and improving the anti-shake effect. At the same time, the block-shaped protrusions 2011 arranged along the length direction of the reinforcing plate 2 also enhance the overall structural strength of the reinforcing plate 2, making the reflector 1 more stable when facing external impacts or vibrations, and reducing the risk of failure caused by structural loosening or damage.

[0039] Please refer to again Figure 2 , a through hole 202 is provided between two adjacent block-shaped protrusions 2012. When subjected to external impacts or vibrations, the design of the through hole 202 can reduce the rigid connection between the block-shaped protrusions 2012, enabling stress to be more easily dispersed in multiple directions, helping to reduce the risk of damage caused by stress concentration, and improving the overall durability of the anti-shake structure. At the same time, the design of the through hole 202 also reduces the material usage on the reinforcing plate 2, thereby reducing the weight of the entire anti-shake structure.

[0040] Please refer to Figure 3, on one side of the reinforcing plate 2 facing the first surface 101, there is an adhesive layer 203. As a connection method between the reinforcing plate 2 and the mirror 1, the adhesive layer 203 can provide strong adhesion, ensuring that the reinforcing plate 2 is firmly adhered to the first surface 101 of the mirror 1. This stable connection method can resist various vibrations and impacts during vehicle driving, preventing the reinforcing plate 2 from loosening or falling off, thereby ensuring the stability and reliability of the mirror 1. At the same time, the design of the adhesive layer 203 simplifies the installation process of the mirror 1. Compared with traditional screw fixation or other mechanical connection methods, using the adhesive layer 203 can eliminate cumbersome fastening steps and tool requirements, making the installation process faster and more convenient.

[0041] Please refer to Figure 1 and Figure 2 , at both ends of the first surface 101, there are connecting parts 103. The connecting parts 103 extend in a direction perpendicular to the first surface 101, and there is at least one reinforcing rib 104 connecting between the connecting parts 103 and the first surface 101. The design of the connecting parts 103 enables the mirror 1 to be more firmly connected to the vehicle. They provide stable support points for the mirror 1 and are closely connected to the first surface 101 through the reinforcing ribs 104, thus forming a solid overall structure. This enhanced connection strength and stability ensure that the mirror 1 can work stably during vehicle driving without being affected by vibrations and impacts. The setting of the reinforcing ribs 104 helps to optimize the stress distribution between the connecting parts 103 and the first surface 101. During vehicle driving, the mirror 1 will be subjected to various vibrations and impacts from the road surface. The reinforcing ribs 104 can absorb and disperse these stresses, preventing structural damage caused by stress concentration, which helps to improve the durability and service life of the head-up display.

[0042] At the same time, on the side of the connecting part 103 facing away from the reinforcing rib 104, there is an installation part 105. The design of the installation part 105 makes the installation process of the mirror 1 more simple and fast. Installers can quickly fix the mirror 1 to other structures on the vehicle through the installation part 105 without complex adjustment and calibration processes.

[0043] Please refer to Figure 2 and Figure 3 , at both ends of the reinforcing plate 2, there are positioning notches 204 that cooperate with the reinforcing ribs 104. The design of the positioning notches 204 enables the reinforcing plate 2 to be quickly and accurately connected to the first surface 101 without complex adjustment and calibration processes, thus simplifying the installation process.

[0044] In one embodiment, a rotating part 106 connected to an external transmission mechanism is provided at the lower end of the mirror 1. A fixed display position may not maintain the best visibility in all cases. The rotating part 106 is designed and connected to the external transmission mechanism so that the driver can adjust the display position of the image projected by the mirror 1 on the windshield according to the actual situation. At the same time, it can also be adjusted according to the driving habits of different drivers to ensure that the information can be accurately projected within the driver's line of sight.

[0045] It should be noted that the material of the reinforcing plate 2 is metal. Metal materials are known for their high strength and durability, which enables the reinforcing plate 2 to effectively resist vibrations, impacts, and stresses generated during vehicle driving. The metal reinforcing plate 2 can ensure that the mirror 1 remains stable under various harsh conditions, thereby extending the service life of the head-up display. In one embodiment, the material of the reinforcing plate 2 is aluminum, which is a lightweight metal. Compared with other common metals such as steel or iron, it has a lower density, so it can significantly reduce the overall weight of the reinforcing plate 2.
