Description

Technical Field

[0001] This utility model relates to the field of head-up display technology, and in particular to a head-up display device. Background Technology

[0002] Head-up displays (HUDs) are an advanced human-computer interaction technology that uses optical projection to present key information (such as speed and navigation commands) within the user's normal field of vision, allowing users to acquire data without interrupting their observation of the external environment. Because this technology significantly improves operational safety and convenience, its applications have gradually expanded from the initial aviation field to driving systems in various vehicles such as automobiles and ships, as well as professional fields such as industrial control consoles.

[0003] To protect the delicate and sensitive optical components inside the device, such as the image generation unit (PGU) and the mirror assembly, these types of projection equipment typically have a transparent protective panel, also known as a dustproof panel, at the exit of its projection light path. The main function of this dustproof panel is to act as a physical barrier, effectively preventing dust, impurities, or accidental contact from damaging the internal optical system, thus ensuring that the device outputs clear images stably and consistently over the long term.

[0004] However, in real-world environments such as vehicle cockpits, dust covers inevitably accumulate dust and dirt due to prolonged exposure. These contaminants directly interfere with the projection light path, causing the projected image to become blurry, severely affecting the readability of information, thus reducing the user experience and even undermining the safety advantages offered by head-up displays. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a head-up display device that can automatically and effectively wet clean surfaces that affect image quality. This solves the problems of inconvenient manual cleaning, poor cleaning effect, and the inability of automated solutions to remove stains in the prior art, thus improving user convenience.

[0006] The technical solution of this utility model embodiment is implemented as follows: In a first aspect, embodiments of the present invention provide a head-up display device, the head-up display device comprising: Spraying device; Cleaning device; A control device is communicatively connected to a spraying device and a cleaning device, and is configured to control the spraying device to spray cleaning liquid onto the surface to be cleaned of the head-up display device, and to control the cleaning device to move on the surface to be cleaned while maintaining contact with the surface to be cleaned, so as to remove the deposits on the surface to be cleaned.

[0007] In some optional examples, the head-up display device also includes a guide device and a storage device in fluid communication with the guide device, wherein the guide device is used to guide the deposits to be removed from the surface to be cleaned to the storage device for storage by the storage device.

[0008] In some optional examples, the head-up display device also includes a discharge device for discharging the deposits stored in the storage device away from the head-up display device.

[0009] In some optional examples, the head-up display device also includes a filtering device disposed in the discharge path of the deposits to filter the deposits before the discharge device discharges them.

[0010] In some alternative examples, the cleaning device is configured to remove deposits from the surface to be cleaned by reciprocating motion on the surface.

[0011] In some optional examples, the head-up display device includes a detection device for detecting deposits on the surface to be cleaned and sending the detection results to a control device.

[0012] In some alternative examples, the control device is configured to control the spraying device to perform a spraying operation and / or control the cleaning device to perform a cleaning operation when the detection results meet predetermined conditions.

[0013] In some optional examples, the head-up display device also includes a drying device that communicates with a control unit, wherein the control unit is also configured to control the drying device to dry the surface to be cleaned.

[0015] In some alternative examples, the control device is also configured to control the cleaning device to perform a cleaning operation after the spraying device has completed its spraying operation, or The control device is configured to control the spraying device to perform spraying operations while simultaneously controlling the cleaning device to perform cleaning operations.

[0016] This utility model provides a head-up display (HUD) device that constructs a complete automated cleaning system by incorporating a spraying device, a cleaning device, and a control device communicatively connected to both.

This technical solution achieves automated wet cleaning of the HUD's surface through the coordinated action of spraying and cleaning, effectively solving the technical problems of inconvenient and ineffective manual cleaning, as well as the inability of methods such as fan blowing to remove stubborn stains in existing technologies. This improves user convenience and ensures that the HUD continuously provides clear projected images. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] During the use of head-up display (HUD) devices, the cleanliness of its dust shield is crucial for ensuring clear projected images and improving user experience. This is because the working principle of HUD systems is based on precise optical projection, and any unexpected interference with the light path will directly reduce the quality of the final image. As the last physical medium before the light leaves the device and enters the human eye, the surface condition of the dust shield has a particularly significant impact on image clarity.

[0026] Specifically, when dust, fibers, and other particles accumulate on the surface of the dustproof panel, these tiny obstacles scatter and obstruct the projected light. Light scattering causes beams of light that should converge to form clear image edges and lines to become diffused, resulting in blurred edges and indistinct outlines of projected text or symbols, reduced overall image contrast, and a "hazy" visual effect. For larger particles or aggregated dust clumps, the obstruction effect can directly create dark spots or patches in the imaging area, potentially obscuring crucial numbers or navigation information and severely impacting information readability.

[0027] Furthermore, when the surface of the dustproof panel is stained with oil, fingerprints, or other liquids, an irregular film forms. This film can cause image distortion. Viewers may see distorted or warped images. This distortion not only reduces the aesthetics and recognizability of the image but also increases the burden on the driver's brain to interpret information, easily leading to visual fatigue after prolonged viewing.

[0028] Therefore, the cleanliness of the dust cover of a head-up display device is crucial for ensuring clear projected images and improving user experience. However, existing technologies still have many shortcomings in solving the problem of dust cover cleaning. Through in-depth research, the inventors have found that these shortcomings are mainly reflected in the following aspects.

[0029] Currently, the most common cleaning method still relies on manual wiping by the user. While this method seems simple, it lacks practical convenience. Head-up displays are typically installed deep within the car dashboard, and the size and position of their dust covers make it difficult for users to easily reach all areas with their hands or tools, resulting in an awkward and strenuous cleaning process. Furthermore, manual wiping easily leaves water stains, fingerprints, or minor scratches from the wiping material itself on the transparent dust cover, creating secondary pollution and potentially causing new visual disturbances, making it difficult to guarantee effective cleaning. In addition, users need to bring their own dedicated cleaning cloths and cleaning agents, and can only clean in specific situations such as when the car is parked, making on-demand cleaning impossible.

[0030] To address the drawbacks of manual cleaning, the inventors considered several automated or semi-automated solutions, but these also failed to completely solve the problem. For example, the inventors considered a cleaning device that uses a dust-blowing component and an electrostatic adsorption plate in conjunction. The operation of this cleaning device mainly consists of two steps: First, a directional airflow is generated by the built-in dust-blowing component to blow away loose dust particles attached to the surface of the dustproof plate; then, the blown-up dust is captured and collected by the electrostatic adsorption plate located to the side to prevent it from settling back onto the dustproof plate.

[0031] However, this cleaning device has two fundamental limitations in practical applications. First, its cleaning method relies entirely on the kinetic energy of the airflow, which means it is only effective for dry, loose dust. It cannot achieve a thorough cleaning of more adhesive stains, such as spots left after liquid has dried, oily fingerprints, or other grime.

[0032] On the other hand, the electrostatic adsorption plate, as a collection device, does not have self-cleaning capabilities. As the adsorbed dust accumulates, its surface gradually becomes saturated and loses its adsorption function, ultimately requiring manual cleaning or replacement by the user, thus failing to fundamentally solve the problem of requiring manual maintenance by the user.

[0033] To address the aforementioned problems, the inventors have proposed a head-up display device through research and experimentation. This head-up display device can automatically and effectively wet clean surfaces that affect image quality, solving the problems of inconvenient manual cleaning, poor cleaning effect, and the inability of automated solutions to remove stains in existing technologies, thus improving user convenience.

[0034] See Figure 1 The diagram shows a perspective view of a head-up display device 100. The head-up display device 100 includes a housing 101 and an imaging assembly 102 housed within the housing 101. To allow the image generated by the imaging assembly 102 to be projected externally, a transparent dustproof plate 101a is provided on the top of the housing 101. Since this dustproof plate 101a is located in the projection light path of the imaging assembly 102, as explained above, any contaminants adhering to its surface will directly reduce the clarity of the projected image. Therefore, the outer surface of the dustproof plate 101a constitutes the surface S to be cleaned according to this invention. This surface S to be cleaned covers the imaging area of ​​the head-up display device 100 to ensure that the driver obtains a clear virtual image.

[0035] To automatically remove deposits from the surface S to be cleaned, according to some embodiments of the present invention, the head-up display device 100 can integrate a cleaning system. This cleaning system may include a spraying device 10, a cleaning device 20, and a control device 30. The control device 30 can be communicatively connected to the spraying device 10 and the cleaning device 20. The control device 30 can be configured to control the spraying device 10 to spray cleaning liquid onto the surface S to be cleaned on the head-up display device 100, and to control the cleaning device 20 to move on the surface S while maintaining contact with it, thereby removing deposits from the surface S.

[0036] The spraying device 10 can be connected to a cleaning liquid source (not shown) or has its own cleaning liquid, and is used to apply the cleaning liquid to the surface S to be cleaned. The cleaning liquid can wet, soften, or dissolve the adhering substances, thereby transforming the originally difficult-to-treat solid, adhesive stains into a liquid or semi-solid form that is easier to remove by physical means. To achieve effective spray coverage, the spraying device 10 can be placed near the surface S to be cleaned and can adopt various specific structures. For example, in Figure 1 In one embodiment, the spraying device 10 may be a single nozzle positioned at one edge of the surface S to be cleaned, and its spraying direction and range are designed to cover the entire surface S. In another embodiment, as shown... Figure 2 As shown, the spraying device 10 can also be a linear spraying pipe with multiple spray holes, which achieves uniform spraying through the coordinated operation of multiple spray holes.

[0037] Of course, the above embodiments are for illustrative purposes only and are not intended to limit the specific form of the spraying device 10. In other embodiments not shown, the spraying device 10 may also be an oscillating nozzle capable of oscillating to expand the spraying range, or other equivalent structures. Furthermore, the spray pattern of the cleaning liquid may be a mist, a jet, or a fan shape to adapt to different cleaning needs and the size of the surface to be cleaned. All these variations fall within the protection scope of this utility model.

[0038] The cleaning device 20 is used to remove adhering substances by physical movement while maintaining contact with the surface S to be cleaned. To ensure close contact with the surface S during movement for optimal cleaning effect, the part of the cleaning device 20 that contacts the surface S can be made of a material with a certain degree of elasticity and flexibility. The specific structure of the cleaning device 20 can vary. For example, the cleaning device 20 can be a roller brush with soft bristles on its surface, a water-absorbing sponge roller, or a soft scraper made of polymer material, etc.

[0039] In one embodiment of this utility model, such as Figure 1As shown, the cleaning device 20 may include a swing arm 20a and a scraper 20b, wherein the scraper 20b remains in contact with the surface to be cleaned S and may be made of a flexible material such as silicone. To efficiently and thoroughly remove deposits, the cleaning device 20 may be configured to reciprocate on the surface to be cleaned S. Specifically, the swing arm 20a may be driven to rotate about one end, causing the scraper 20b connected to its other end to move from one side (e.g., the left side) to the other side (e.g., the right side) of the surface to be cleaned S, and then move back in the opposite direction, completing one full cleaning cycle. Through this direct physical contact and reciprocating movement, the cleaning device can effectively peel off and remove deposits softened by the cleaning fluid from the surface to be cleaned S, completing the key physical removal operation in the cleaning process.

[0040] The control device 30 acts as the brain of the entire cleaning system, coordinating the operation of each component. In some embodiments of this invention, the control device 30 may be a control board and its microcontroller (MCU) inside a head-up display device. The control device 30 can communicate with the spraying device 10 and the cleaning device 20 via circuitry, sending drive commands to them, or it can send drive commands wirelessly. For example, the control device 30 can send a drive command to the cleaning device 20, which, upon receiving the command, can drive the swing arm 20a to reciprocate, causing the scraper 20b to reciprocate as well, thus achieving the cleaning operation. The control device 30 integrates multiple cleaning steps that originally required manual execution, such as spraying water and wiping, into an automated process controllable by electrical signals, forming the basis for automated cleaning.

[0041] This invention provides a head-up display (HUD) device 100, which constructs a complete automated cleaning system by incorporating a spraying device 10, a cleaning device 20, and a control device 30 communicatively connected to both. When cleaning is required, the control device 30 coordinates the spraying device 10 to apply cleaning fluid to soften and dissolve adhering substances, and controls the cleaning device 20 to thoroughly remove the adhering substances through physical contact movement. This technical solution achieves automated wet cleaning of the surface of the HUD device through the coordinated operation of spraying and cleaning, effectively solving the technical problems of inconvenient and ineffective manual cleaning, as well as the inability of methods such as fan blowing to remove stubborn stains in the prior art. This improves user convenience and ensures that the HUD device can continuously provide clear projected images.

[0042] The cleaning system for head-up display devices provided in this embodiment of the invention can cover multiple working modes to adapt to different usage scenarios and levels of contamination.

[0043] For example, in a preferred embodiment, the control device 30 can execute a "spray first, then remove" strategy. That is, the control device 30 can first activate the spraying device 10 to spray a sufficient amount of cleaning liquid onto the surface S to be cleaned. After a short delay to fully wet and dissolve stubborn stains, the removal device 20 is then activated to scrape and remove the stains. This strategy, through the pre-wetting process, is most effective for treating dried, highly adhesive stains such as juice and oil stains, and can significantly improve the success rate and thoroughness of cleaning.

[0044] Of course, the control device 30 can also be configured to perform a faster cleaning mode. For example, when it is necessary to quickly remove dust or less serious stains, a strategy of simultaneous spraying and cleaning can be adopted. In this mode, the control device 30 can simultaneously activate the spraying device and the cleaning device. As the cleaning device 20 moves, the spraying device 10 continuously sprays cleaning fluid in front of its moving path. The continuous liquid spraying in this process plays a dual role of lubrication and rinsing, which can very quickly clean the surface.

[0045] Furthermore, to address more complex contamination situations, the control device 30 can also execute a more refined multi-step cleaning strategy: "remove first, then spray, then remove again." Under this strategy, the control device 30 first drives the removal device 20 to perform a "dry scraping" on the dry surface to be cleaned, aiming to remove large, loose dust particles and other adhering substances beforehand. Subsequently, the control device 30 activates the spraying device 10 to spray and treat any remaining adhesive stains. Finally, the control device 30 drives the removal device again for a "wet scraping" to thoroughly remove the dissolved stains and residual cleaning fluid. This strategy is the most thorough, as the pre-dry scraping avoids mixing large dust particles with the liquid to form a slurry, thereby improving the efficiency and effectiveness of subsequent wet cleaning and potentially reducing cleaning fluid consumption.

[0046] By implementing the above-mentioned cleaning strategies, the head-up display device of this invention can flexibly and efficiently complete cleaning tasks according to different needs, providing users with a continuously clear projection view and a convenient user experience.

[0047] The head-up display device 100 provided by this utility model is further described in detail below with reference to the embodiments.

[0048] In some embodiments of this invention, the head-up display device 100 may further include a guiding device 40 and a storage device 50 in fluid communication with the guiding device 40. The guiding device 40 is used to guide the deposits to be removed from the surface S to be cleaned to the storage device 50 for centralized storage.

[0049] like Figure 3As shown, the guiding device 40 can be specifically a guiding groove disposed around the edge of the surface S to be cleaned. Considering that the surface S to be cleaned is not usually horizontal, the guiding groove can be arranged along one or more of its lower edges. The guiding groove can be formed in the housing 101 of the head-up display device 100, and its position is convenient for receiving the adhering material removed by the cleaning device 20 under the action of pushing and gravity.

[0050] The guiding device 40 can be in fluid communication with the storage device 50 to collect the deposits therein. In some embodiments, such as Figure 4 As shown, the bottom of the guide groove itself can be designed as a deepened and enlarged structure, thereby directly forming the storage device 50. In an embodiment not shown, the storage device 50 can also be a separate chamber within the housing 101.

[0051] This centralized structure for managing attachments not only effectively prevents wastewater from contaminating other internal components of the head-up display device 100 (such as the imaging component 102), but also facilitates subsequent unified treatment, avoiding pollution of the surrounding environment.

[0052] In order to actively treat and ultimately remove the deposits stored in storage device 50, see Figure 3 and Figure 4 The head-up display device 100 may also include a discharge device 60. In some embodiments of the present invention, the discharge device 60 may be specifically a suction pump and may be disposed at the bottom of the guide device 40 in the form of a guide trough.

[0053] The suction inlet of the discharge device 60 can be connected to the storage device 50, while its discharge outlet faces the external discharge path of the head-up display device 100. Additionally, a liquid level sensor (not shown) can be installed in the storage device 50. When the storage device 50 needs to be emptied, for example, after each cleaning task, or when the liquid level sensor detects that it is full, the discharge device 60 can be activated to actively extract the stored deposits and pump them into the subsequent discharge path.

[0054] Compared to emission structures that rely on gravity or other passive methods, the emission device 60 provides active and reliable emission power, ensuring that stored deposits can be discharged in a timely and thorough manner regardless of the vehicle's posture, such as when parked on a slope, thus avoiding liquid buildup, overflow, or odor caused by poor emission.

[0055] Furthermore, to improve the long-term operational reliability of the cleaning system, see [link to relevant documentation]. Figure 5The head-up display device 100 may also include a filter device 70. In some embodiments of the present invention, the filter device 70 may be in the form of a filter screen. The filter device 70 may be disposed downstream of the discharge path of the discharge device 60. In this way, all adhering material extracted by the discharge device 60 must pass through the filter device 70 before being finally discharged from the head-up display device 100.

[0056] During the cleaning process, the deposits may contain large solid particles such as dust and fibers. These particles tend to accumulate at pipe bends or the final outlet as they flow through the discharge path, causing blockages. By installing a filter device 70, large solid particles can be intercepted before the deposits reach these narrow areas. This fundamentally prevents blockages at the equipment's outlet, avoiding the risk of wastewater backflow or discharge failure due to blockages, thus ensuring the long-term, maintenance-free, and reliable operation of the entire wastewater management system.

[0057] To further enhance the automation level of the head-up display device 100 and enable it to autonomously determine when cleaning is needed, the head-up display device 100 may also include a detection device 80. The detection device 80 can be used to determine whether the deposits on the surface S to be cleaned have reached a level that requires cleaning, and send the determination result to the control device 30.

[0058] In some embodiments of this utility model, such as Figure 6 As shown, the detection device 80 can be a light sensor and can be positioned at one edge of the surface S to be cleaned, enabling it to detect deposits on the entire surface S. The detection device 80 can be used to collect light signals passing through or reflected from the surface S. When the surface is clean, the light signal is at a baseline state; when deposits accumulate, they block or scatter the light, causing a measurable change in the light signal. The control device 30 can then determine the location of the deposits based on the degree of this signal change, thereby determining whether the predetermined cleaning conditions have been met.

[0059] Those skilled in the art will understand that the aforementioned light sensor is merely one specific implementation of the detection device. Any device capable of detecting changes in the state of a surface to be cleaned can be used in this invention. For example, in other alternative embodiments, the detection device 80 can also be an image sensor (e.g., a miniature camera). In this case, the detection device 80 can be used to capture images of the surface to be cleaned, and the control device 30 or its associated processor can analyze the images to determine whether the predetermined cleaning conditions have been met by identifying spots or stains in the images or comparing them with images of a clean state. Alternatively, the detection device 80 can also be a capacitive sensor, which determines the degree of dirtiness by detecting changes in the surface dielectric constant caused by deposits, particularly water stains or oil stains.

[0060] Regardless of the specific form used, the detection device 80 sends the corresponding detection results to the control device 30. The control device 30 is configured to automatically initiate the cleaning process when the received detection results meet predetermined conditions, i.e., controlling the spraying device 10 to perform spraying operations and / or controlling the cleaning device 20 to perform cleaning operations. This structure enables the head-up display device 100 to have intelligent sensing and autonomous decision-making capabilities, automatically cleaning when surface dirt affects use without constant user attention or manual intervention, thus improving the automation level of the equipment and the convenience of the user experience.

[0061] After wet cleaning, a small amount of cleaning solution or water stains may remain on the cleaned surface S. These residual droplets will form watermarks after drying, which can also interfere with the light path and affect the clarity of the projected image. To solve this problem, see [link to relevant documentation]. Figure 7 The head-up display device 100 shown may also include a drying device 90.

[0062] In some embodiments of this invention, the drying device 90 may include a miniature fan 91 and one or more air outlets 92 aligned with the surface S to be cleaned. In some embodiments, the drying system 7 may also include a heating element (not shown), such as a PTC heating element, for heating the blown airflow to improve drying efficiency. The drying device 90 may be positioned at one edge of the surface S to be cleaned, so that the drying area covers the entire surface S to be cleaned as much as possible.

[0063] The drying device 90 can be communicatively connected to the control device 30. In this case, the control device 30 can be configured to activate the drying device when needed, for example, after the cleaning device 20 has completed its cleaning operation. Once activated, the drying device 90 can blow airflow onto the surface S to be cleaned, quickly evaporating or blowing away any residual droplets or water stains. Alternatively, if a guide device 40 is provided, the blown-away water stains can be guided into the guide device 40.

[0064] Because the drying device 90 can actively and quickly remove residual droplets after wet cleaning, it avoids the formation of visually unsightly watermarks during the natural air drying process. This ensures that users can immediately obtain a completely clean and undisturbed projection surface after the cleaning work is completed, directly improving the final effect of the cleaning solution and the immediacy of the user experience.

[0065] The head-up display device of this invention is particularly suitable for use in vehicle environments. Considering the potential safety hazards of performing cleaning operations while the vehicle is in motion, as the sprayed cleaning fluid and the movement of the cleaning device can not only directly interfere with the projected virtual image observed by the driver due to obstruction or light refraction, but may also distract the driver's attention due to sudden movements inside the dashboard.

[0066] In order to fundamentally eliminate this hidden danger, according to some embodiments of the present invention, a rigorous safety interlock structure is integrated through the control device 30.

[0067] Specifically, the control device 30 can communicate with the vehicle's bus system, such as a CAN bus (not shown in the figure), to obtain signals such as gear position and vehicle speed in real time, accurately determining whether the vehicle is in a parked state. Upon receiving a cleaning command, the control device 30 first performs a safety check. Only when it determines that the vehicle is indeed in a parked state will the control device 30 authorize and continue the subsequent spraying and cleaning operations. Conversely, if it determines that the vehicle is in motion, the control device 30 will interrupt or delay the cleaning process and can temporarily store the cleaning command. It can also display a prompt message such as "It is recommended to clean after parking" to the driver via a head-up display device until the vehicle comes to a complete stop before proceeding. Through this vehicle-state-based safety interlock structure, this invention limits the cleaning function to execution under absolutely safe conditions, effectively avoiding interference with the driving process and improving the product's safety and applicability in the vehicle environment.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
