Description

Technical Field

[0001] This application relates to the field of HUD, and more specifically, to a dustproof structure for HUD and an in-vehicle HUD. Background Technology

[0002] The dustproof structure is the outermost component of a HUD (Head-Up Display) system, covering the surface of the HUD optical components to protect them. This dustproof structure may include a dustproof film and a protective film. The protective film covers the surface of the dustproof film to prevent it from being scratched during production or transportation.

[0003] An operating component is located on the side of the protective film opposite to the dustproof film, used to peel off the protective film. The existing dustproof structure's position means that after the HUD and trim panel are assembled to the main body of the device, the operating component is located between the protective film and the trim panel, with a gap of only about 3mm to 5mm. Operators cannot easily see the operating component through the through-holes in the trim panel, making it difficult to peel off the protective film using the operating component, resulting in low work efficiency. Utility Model Content

[0004] The technical problem to be solved by this application is to provide an improved HUD dustproof structure and vehicle-mounted HUD, addressing the aforementioned deficiencies of the prior art.

[0005] The technical solution adopted by this application to solve its technical problem is: constructing a dustproof structure for a HUD, including:

[0006] The dustproof film includes a first region and a second region located on the periphery of the first region;

[0008] An operating component is disposed on the side of the protective film opposite to the dustproof film; the operating component includes an operating part and a fixing part fixed to the protective film;

[0009] Wherein, at least a portion of the operating part's orthographic projection on the plane where the dustproof film is located overlaps with the first region.

[0010] In some embodiments, the orthographic projection of the fixing portion onto the plane where the dustproof film is located overlaps with the second region.

[0011] In some embodiments, a portion of the sidewall of the fixing portion overlaps with a portion of the sidewall of the protective film;

[0012] Alternatively, a portion of the side of the fixing part is parallel to a portion of the side of the protective film, and the distance between them is less than or equal to 1 mm.

[0013] In some embodiments, the fixing part is fixed to the corner of the protective film.

[0014] In some embodiments, the angle between the extension direction of the operating part and the extension direction of the angle bisector of the angle defined by the two adjacent sides of the protective film at the corner where the fixing part is located is greater than or equal to 0° and less than or equal to 30°.

[0015] In some embodiments, the operating part is longitudinally elongated, and the fixing part is located at one end of the operating part; at least a portion of the dimension of the fixing part perpendicular to the extending direction of the operating part is greater than the dimension of the operating part perpendicular to its extending direction.

[0016] In some embodiments, the actuating element is sheet-shaped.

[0017] In some embodiments, the length of the orthographic projection of the operating part onto the plane where the dustproof film is located, overlapping the first region, is greater than or equal to 2.5 cm and less than or equal to 5 cm.

[0018] In some embodiments, an adhesive layer is provided between the fixing part and the protective film to fix the two together.

[0019] A vehicle-mounted HUD is constructed, comprising a HUD body and a dustproof structure for the HUD as described in any of the preceding embodiments; the dustproof film is disposed on the side of the HUD body opposite to the protective film.

[0034] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "up", "down", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product of this application is in use. They 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. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] Figures 1 to 6 A dustproof structure 1 for a HUD according to one embodiment of this application is shown, which may include a dustproof film 11, a protective film 12, and an operating component 13. The protective film 12 is detachably attached to one side of the dustproof film 11 to protect it from scratches during production, assembly, and transportation. The operating component 13 is located on the side of the protective film 12 opposite to the dustproof film 11 and is partially fixed to it. An operator can peel the protective film 12 off the dustproof film 11 by pulling the operating component 13.

[0040] It should be understood that the HUD includes a HUD dustproof structure 1 and a HUD body (not shown in the figure). When the HUD dustproof structure 1 is assembled with the HUD body, the side of the dustproof film 11 facing away from the protective film 12 is disposed on the HUD body for dust prevention and protection. More specifically, the dustproof film 11 covers the outside of the optical components of the HUD body, and the protective film 12 covers the side of the dustproof film 11 facing away from the optical components.

[0041] like Figure 6 and Figure 9As shown, the device includes a main body (not shown) and a decorative panel 2, which defines a through-hole 21. During assembly, the HUD is typically assembled to the main body first, followed by the decorative panel 2. After the decorative panel 2 is assembled to the main body, it is positioned at the top of the HUD, with the HUD dustproof structure 1 located between the HUD main body and the decorative panel 2. The port 211 of the through-hole 21 near the HUD dustproof structure 1 is smaller than the port size away from the HUD dustproof structure 1, allowing the HUD's optical components to display information through the through-hole 21 of the decorative panel 2.

[0042] It should be understood that the device can include many types such as vehicles, airplanes, AR glasses, ships, and medical devices, and no specific limitation is made here.

[0043] like Figure 5 As shown, the dustproof film 11 is membrane-like, comprising an integral first region 111 and a second region 112. The second region 112 surrounds the outer periphery of the first region 111. The outline of the first region 111 can be adapted to the outline of the port 211 of the through-hole 21 of the trim panel 2 near the HUD dustproof structure 1. Alternatively, the outline of the first region 111 is slightly smaller than the outline of the port 211 to avoid assembly tolerances during the assembly of the trim panel 2 and the HUD, which could cause the outline of the port 211 to obstruct the HUD image display. (See also...) Figure 6 When the HUD and the trim panel 2 are assembled to the main body of the device, the first area 111 can be exposed through the through hole 21, and the second area 112 is located between the trim panel 2 and the HUD main body.

[0044] The protective film 12 is in the form of a film, and its shape and size are consistent with the dustproof film 11, so as to overlap the dustproof film 11 on the side away from the vehicle HUD optical components, and the two are detachably and completely attached.

[0045] like Figures 1 to 4 As shown, the operating component 13 includes an operating part 131 and a fixing part 132. The fixing part 132 is fixed to the side of the protective film 12 facing away from the dustproof film 11. The operating part 131 is connected to the fixing part 132 and is located on the side of the protective film 12 facing away from the dustproof film 11. At least a portion of the operating part 131 is positioned such that its orthographic projection onto the plane of the dustproof film 11 overlaps with the first region 111.

[0046] It should be understood that the operating part 131 and the protective film 12 are not directly fixed together; they can be... Figure 3 As shown, it is spaced apart from the dustproof film 11, or it may be flexible, such as Figure 4The protective film 12 is at least partially attached to the protective film 12, but no specific limitation is made here. Since the operating part 131 and the protective film 12 are respectively connected to the fixing part 132, the operator can pull the operating part 131 to move the fixing part 132 and the protective film 12, thereby tearing the protective film 12 off the dustproof film 11.

[0047] It should be understood that during the equipment assembly process, the protective film 12 is usually removed after the HUD and the decorative panel 2 have been assembled to the main body of the equipment, in order to carry out the subsequent HUD optical calibration steps.

[0048] like Figure 6 As shown, after the HUD and trim panel 2 are assembled to the main body of the device, the first area 111 can be exposed through the through hole 21, and at least a portion of the operating part 131's orthographic projection on the plane where the dustproof film 11 is located overlaps with the first area 111. Therefore, at least a portion of the operating part 131 can be exposed through the through hole 21 of the trim panel 2. The operator can pull the operating part 131 through the through hole 21 to peel the protective film 12 off the dustproof film 11.

[0049] It is necessary to understand that, for example, Figure 7 and Figure 8 As shown, in the HUD dustproof structure 1A of the related technology, the fixing part 132A of the operating member 13A is mostly fixed at the edge of the protective film 12A, while the operating part 131A extends from the fixing part 132A in a direction away from the protective film 12A, so that its orthographic projection on the plane where the dustproof film 11A is located does not overlap with the dustproof film 11A.

[0050] It is necessary to understand that, such as Figure 9 As shown, when both the HUD and trim panel 2 are assembled into the main body of the device, the distance D between the HUD dustproof structure and trim panel 2 is only 3mm to 5mm. (See also...) Figure 7 and Figure 10 In the related technology, the edge of the protective film 12A fixed by the fixing part 132A of the HUD dustproof structure 1A is located between the decorative panel 2 and the HUD body, and the operating part 131A extends from the fixing part 132A away from the protective film 12A. Therefore, when the HUD and the decorative panel 2 are assembled to the device body, the operating part 13A is blocked by the decorative panel 2, making it difficult for the operator to see the operating part 13A and even more difficult to peel off the protective film 12A through the operating part 13A. This arrangement affects assembly efficiency.

[0051] like Figure 11As shown, in order to avoid affecting assembly efficiency, operators generally choose to peel off part of the protective film 12A through the operating part 131A of the operating component 13A after the HUD is assembled to the main body of the equipment and before the trim panel 2 is assembled to the main body of the equipment. Then, they fold the peeled protective film 12A in half so that the orthographic projection of the operating component 13A on the plane where the dustproof film 11A is located roughly overlaps with the middle part of the dustproof film 11A.

[0052] Next, the operator assembles the decorative panel 2 onto the main body of the equipment. At this time, the operator can see the operating part 13A and the protective film 12A that has been peeled off through the through hole 21. Then, the operator pulls the operating part 131A through the through hole 21 to completely peel the protective film 12A off the dustproof film 11.

[0053] While this method of operation does not significantly affect assembly efficiency, it poses a potential risk of scratching the dustproof film 11A during the period between when the protective film 12A is partially peeled off and when it is completely peeled off.

[0054] This application adjusts the position of the orthographic projection of the operating part 13 on the plane where the dustproof film 11 is located, so that the orthographic projection of the operating part 131 overlaps with the first region 111. Furthermore, after the HUD and the trim panel 2 are both assembled to the main body of the device, the operating part 131 can be exposed through the through hole 21 of the trim panel 2, so that the operator can pull the operating part 131 through the through hole 21 to remove the protective film 12.

[0055] This setup is simple and efficient to operate, while avoiding the problem of scratching the dustproof film 11 that would easily occur when the protective film 12 is removed before the trim panel 2 is assembled. In other words, it can ensure assembly efficiency while reducing assembly waste.

[0056] It should be understood that the shape and size of the dustproof film 11 and the protective film 12 can be flexibly set according to the specific structure of the HUD, the structure of the optical components, and the structure of the equipment to which the HUD is mounted. For example, the shape of the dustproof film 11 and the protective film 12 can be set as rectangular, trapezoidal, circular, elliptical, polygonal, irregular, etc., and no specific limitation is made here.

[0057] It should be understood that the shape and size of the first part 111 can be flexibly set according to the shape and size of the through hole 21 of the decorative panel 2. Specifically, it can be rectangular, trapezoidal, circular, elliptical, polygonal, irregular, etc. The specific size of the first part 111 can be slightly larger than the size of the port 211 of the through hole 21 near the HUD dustproof structure 1, or slightly smaller than the size of the port 211 of the through hole 21 near the HUD dustproof structure 1. No specific limitation is made here.

[0058] The protective film 12 is detachably disposed on one side of the dustproof film 11. Specifically, it can be achieved through existing technologies such as microstructure adhesion, electrostatic adsorption, and setting a low-tack adhesive layer, without being specifically limited here.

[0059] The dustproof film 11 and the protective film 12 can be made using existing technologies. For example, the dustproof film 11 can be made of transparent polycarbonate film (PC) and adhesive layer, and the protective film 12 can be made of polyethylene (PE) and adhesive layer, polypropylene (PP) and adhesive layer, etc. No specific limitation is made here.

[0060] In some other embodiments, the protective film 12 may be larger than the dustproof film 11, and the shape of the protective film 12 may also be different from that of the dustproof film 11. Its shape and size are designed to cover the outer surface of the dustproof film 11, thus providing protection.

[0061] For example Figures 1 to 4 As shown, in some embodiments, the operating member 13 is in the form of a sheet or a film, and the operating part 131 and the fixing part 132 are integrally disposed.

[0062] In some other alternative embodiments, the operating element 13 may also be an integral line. Alternatively, one of the operating portion 131 and the fixing portion 132 of the operating element 13 may be sheet-like or membrane-like, and the other may be line-like, with the two fixedly disposed together.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the operating part 131 is longitudinally arranged, with one end connected to the fixing part 132 and the other end extending from the fixing part 132 to the position corresponding to the first region 111.

[0064] Specifically, the operating part 131 may be in the form of a longitudinally elongated straight strip.

[0065] For example, in Figure 1 In the illustrated embodiment, the operating member 13 is arrow-shaped, and the fixing part 132 is arrowhead-shaped. The operating part 131 is an elongated rectangle, with one end connected to the fixing part 132, so as to be regarded as the shape of an arrow shaft.

[0066] In some other embodiments, the operating part 131 may also be in the form of a vertically elongated or slender ellipse, rhombus or other straight strip shape, or it may be in the form of a vertically elongated or slender polygon, wave shape, arc shape, S shape, L shape, irregular shape or other strip shape, or it may be in the form of a line shape or other shapes.

[0067] In some embodiments, the length L of the orthographic projection of the operating part 131 onto the plane where the dustproof film 11 is located, overlapping the first region 111, is greater than or equal to 2.5 cm and less than or equal to 5 cm. That is, the length L of the operating part 131 exposed in the first region 111 is greater than or equal to 2.5 cm and less than or equal to 5 cm.

[0068] Specifically, the length L can be 2.6cm, 2.7cm, 2.8cm, 2.9cm, 3cm, 3.1cm, 3.2cm, 3.3cm, 3.4cm, 3.5cm, 3.6cm, 3.7cm, 3.8cm, 3.9cm, 4cm, 4.1cm, 4.2cm, 4.3cm, 4.4cm, 4.5cm, 4.6cm, 4.7cm, 4.8cm, 4.9cm, or any other value within this range.

[0069] The two adjacent sides at the corner of the protective film 12 where the fixing part 132 is located are now defined as the first side 121 and the second side 122, respectively.

[0070] Then as Figure 1 As shown, in some embodiments, the angle α between the extension direction S1 of the operating part 131 and the extension direction S2 of the angle bisector of the angle defined by the first side 121 and the second side 122 is greater than or equal to 0° and less than or equal to 30°.

[0071] Specifically, the included angle α can be 2°, 4°, 6°, 8°, 10°, 12°, 14°, 16°, 18°, 20°, 22°, 24°, 26°, 28°, or any other value within this range. When the included angle α is 0°, the operating part 131 extends along the angle bisector defined by the first side 121 and the second side 122.

[0072] exist Figure 1 In the illustrated embodiment, the extending direction of the operating part 131 is such that it is located away from the end of the fixing part 132, and as far away as possible from the first side 121 and the second side 122. Furthermore, as Figure 6 As shown, after the HUD and the trim panel 2 are assembled to the main body of the device, the end of the operating part 131 away from the fixing part 132 can be as far away from the edge of the port 211 of the through hole 21 as possible, so that the operator can pull the operating part 131 through the through hole 21.

[0073] In some other embodiments, the extending direction of the operating part 131 may also form an angle with the angle bisector. This extending direction allows the operator to easily pull the operating part 131 through the through hole 21.

[0074] like Figure 5As shown, in some embodiments, the orthographic projection of the fixing part 132 on the plane where the dustproof film 11 is located overlaps with the second region 112. Since the second region 112 is located on the outer periphery of the first region 111, at the edge of the dustproof film 11, and the dustproof film 11 and the protective film 12 overlap, this arrangement allows the operator to easily peel off the protective film 12 by opening the edge of the protective film 12 through the operating part 131.

[0075] Specifically, a portion of the side of the fixing part 132 may overlap with a portion of the side of the protective film 12.

[0076] Of course, in some other embodiments, a portion of the side of the fixing part 132 may also substantially overlap with a portion of the side of the protective film 12, that is, the two are arranged in parallel intervals, and the interval between them is less than or equal to 1 mm. Specifically, the interval between the parallel intervals between the fixing part 132 and the protective film 12 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or any other value within this area.

[0077] In some embodiments, when the protective film 12 has corners, the fixing part 132 is fixed to the corners of the protective film 12.

[0078] Furthermore, the fixing part 132 may include two adjacent sides, which are respectively overlapped with the two adjacent sides at the corners of the protective film 12.

[0079] For example, in Figure 1 In the illustrated embodiment, the operating member 13 is arrow-shaped, and the fixing part 132 is generally arrow-shaped, with the angle of its arrowhead tip being consistent with the angle between the two adjacent sides at the corner of the protective film 12. That is, the fixing part 132 defines the two adjacent sides of the arrowhead tip, which are respectively overlapped with the first side 121 and the second side 122 adjacent to the corner of the protective film 12.

[0080] Specifically, please refer to the following: Figure 2 The fixing part 132 includes a first part 1321 and a second part 1322. Both the first part 1321 and the second part 1322 are elongated and extend along the adjacent two sides of the corner of the protective film 12.

[0081] When a portion of the fixing part 132 is also parallel and spaced apart from a portion of the protective film 12, the fixing part 132 defines the adjacent two sides of the arrow tip, which are respectively parallel and spaced apart from the first side 121 and the second side 122 of the protective film 12, and the spacing distance is less than or equal to 1 mm.

[0082] In some other alternative embodiments, the fixing part 132 may also be fan-shaped, polygonal, L-shaped, irregularly shaped with adjacent two sides, or other shapes with adjacent two sides.

[0083] In some other embodiments, when the fixing part 132 is fixed to the corner of the protective film 12, its side edge may overlap only one side of the corner of the protective film 12, or it may not overlap with either side of the corner. In this case, the fixing part 132 may be specifically configured as various shapes such as circular, elliptical, semi-circular, semi-elliptical, polygonal, irregular, etc., without specific limitation.

[0084] In some other embodiments, when the size of the protective film 12 is larger than that of the dustproof film 11 and the fixing part 132 is located at the edge of the protective film 12, the orthographic projection of the fixing part 132 on the plane where the dustproof film 11 is located can also be provided without overlapping with the dustproof film 11.

[0085] like Figure 2 As shown, in some embodiments, at least a portion of the fixing portion 132 has a dimension L2 perpendicular to the extension direction of the operating portion, which is larger than the dimension L1 perpendicular to the extension direction of the operating portion 131.

[0086] It is necessary to understand that, such as Figure 7 As shown, in the related HUD dustproof structure 1, the operating member 13A extends in a generally linear manner, while the operating part 131A and the fixing part 132A are both strip-shaped. This arrangement is not conducive to the stability of the fixation between the fixing part 132A and the protective film 12A.

[0087] This application improves the reliability of the fixation between the fixing part 132 and the protective film 12 by setting the shape of the fixing part 132 such that at least part of its dimension L2 perpendicular to the extension direction of the operating part is greater than the dimension L1 perpendicular to the extension direction of the operating part 131, thus ensuring the operability of the operator when peeling off the protective film 12 through the operating member 13.

[0088] like Figure 3 and Figure 4 As shown, in some embodiments, the HUD dustproof structure 1 further includes an adhesive layer 14. The adhesive layer 14 is disposed between the fixing part 132 and the protective film 12, and is used to fix the fixing part 132 and the protective film 12 together.

[0089] Specifically, the adhesive layer 14 can overlap with the fixing part 132 to ensure the fixing effect between the fixing part 132 and the protective film 12.

[0090] Of course, the shape of the adhesive layer 14 may be different from that of the fixing part 132, and its size may be smaller than that of the fixing part 132.

[0091] It should be understood that the adhesive layer 14 can specifically adopt existing technologies such as substrate-free double-sided adhesive, and will not be specifically limited here.

[0092] In some other alternative embodiments, the fixing part 132 may also be fixed to the protective film 12 by means of integral molding or other methods.

[0093] This application also constructs an in-vehicle HUD, which may include the HUD dustproof structure constructed in any of the foregoing embodiments.

[0094] In this embodiment, the aforementioned device is a vehicle. The vehicle-mounted HUD and trim panel 2 can be mounted on the vehicle's instrument panel mounting beam.

[0095] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0096] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
