Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, in particular to a sunshade, a headlight optical system and a vehicle. Background Art

[0002] For low beam modules or high and low beam integrated modules, many lighting modules now use a shading plate to form a low beam and dark cut-off line, which has the advantages of low cost and easy modification. The high reflectivity of the shading plate itself can also further improve the luminous flux and brightness of the low beam.

[0003] Vehicles in the global market are divided into two types: left-hand drive and right-hand drive. Since the shapes of the low beam cut-off lines of these two types of vehicles are opposite, when making two different types of vehicles, it is often necessary to make two sunshades with different structures, which undoubtedly greatly increases the production and manufacturing cost of the lighting module.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, the terms "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. It should be further explained that if the light converges to the focus, it does not mean that it converges to the focus in the strict sense, but it can also be near the focus (<2mm). Similarly, the focus is set at the cutoff line structure, which includes both the focus being set on the cutoff line structure and the focus being set near the cutoff line structure.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Please refer to Figures 1 to 18 The embodiment of the present application provides a sunshade 10, including a sunshade body 11, and mounting structures 110 are arranged on opposite sides of the sunshade body 11. The mounting structures 110 are used to install the sunshade body 11 between the primary optical element 20 and the light emitting element 30 of the vehicle light optical system 100. The other two side boundaries of the sunshade body 11 arranged in the light path are both provided with cut-off line structures 112, which are respectively a left-hand drive cut-off line structure 1121 and a right-hand drive cut-off line structure 1122. The focus of the light emitting element 30 is located at the left-hand drive cut-off line structure 1121 or the right-hand drive cut-off line structure 1122, so that the light emitted by the light source is converged by the primary optical element 20 and then cut off by the sunshade 10, and then enters the light emitting element 30 and is emitted by the light emitting element 30 to form a light emitting light pattern with a bright and dark cut-off line. The sunshade 10 has high versatility and can solve the problem that the existing lighting modules used for left-hand drive vehicles and right-hand drive vehicles need to manufacture two sunshades with different structures, thereby reducing the production and manufacturing cost of the lighting module.

[0045] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the sun visor 10 includes a sun visor body 11, and mounting structures 110 extend from opposite sides of the sun visor body 11. At least one mounting hole 111 is respectively provided on the two mounting structures 110, so that the sun visor body 11 can be installed between the primary optical element 20 and the light emitting element 30 of the vehicle light optical system 100 through the mounting structure 110. At the same time, the other two side boundaries of the sun visor body 11 disposed in the light path are respectively provided with a left-hand drive cut-off line structure 1121 and a right-hand drive cut-off line structure 1122. Regardless of whether the sun visor 10 is installed forward or reverse, the light emitted by the light source can pass through the cut-off line structure 112 of the sun visor body 11 after being converged by the primary optical element 20. After being cut off, the light is emitted by the light emitting element 30 to form a light output light pattern with a bright and dark cut-off line. Among them, the so-called forward installation of the sun visor 10 refers to when the sun visor 10 is applied to a left-hand drive vehicle, such as Figure 3 In the installation mode shown in the figure, the light is cut off by the left-hand driving cut-off line structure 1121, as shown in FIG. Fig.17As shown, the left-hand drive cut-off line structure 1121 is disposed close to the light emitting element 30, and the focus of the light emitting element 30 is also located at the left-hand drive cut-off line structure 1121; and the so-called reverse installation of the shading plate 10 refers to the shading plate 10 being applied to a right-hand drive vehicle, such as Figure 7 In the installation mode shown in the figure, the light is cut off by the right-hand cut-off line structure 1122, as shown in FIG. Fig.18 As shown, similarly, the right-hand drive cut-off line structure 1122 is also arranged close to the light emitting element 30, and the focus of the light emitting element 30 is also located at the right-hand drive cut-off line structure 1122. It is clear to those skilled in the art that when applied to a left-hand drive vehicle, the left-hand drive cut-off line structure 1121 can be as follows: Figure 2 As shown in FIG. 1 , the left side is lower and the right side is higher. When applied to a right-hand drive vehicle, the right-hand drive cut-off line structure 1122 can be as follows Figure 6 Of course, the cut-off line structure 112 also has other shapes, such as a "bathtub" shape. The present application does not limit the shape of the cut-off line structure 112. It only needs to meet the requirements of the cut-off line structure 112 on one side of the sunshade body 11 for left-hand drive vehicles and the cut-off line structure 112 on the other side for right-hand drive vehicles.

[0046] Furthermore, since the sun visor body 11 has both a left-hand drive cut-off line structure 1121 that satisfies a left-hand drive vehicle and a right-hand drive cut-off line structure 1122 that satisfies a right-hand drive vehicle, the sun visor 10 can be installed on a left-hand drive vehicle when it is properly installed. If it is necessary to install the sun visor 10 on a lighting module of a right-hand drive vehicle, it is only necessary to change its installation method, that is, to flip the sun visor 10 front and back. There is no need to use different molds to manufacture different sun visors. The sun visor 10 provided in the present application has high versatility and can effectively reduce the production and manufacturing cost of the headlight optical system 100.

[0047] like Figures 1 to 12 As shown, as an implementable manner, the shape of the cut-off line structure 112 is a broken line segment or a "bathtub" shape to meet the requirements of different users on the shape of the light cut-off line of the light output light type; Figure 2 and Figure 6 As shown, the inclination angle α of the broken line segment ranges from 130° to 170° to meet the legal requirements for the shape of the bright and dark cut-off line. Figures 1 to 8 As shown, the shape of the cut-off line structure 112 is a broken line segment; Figures 9 to 12 As shown, the cutoff structure 112 has a "bathtub" shape.

[0048] like Figures 1 to 8 As shown, as an implementable manner, the cut-off line structure 112 is divided into a first portion R1 and a second portion R2, and the first portion R1 is lower than the second portion R2 in the vertical direction; Figures 1 to 4As shown, when applied to a left-hand drive vehicle, the sunshade body 11 is installed and fixed in a layout manner (i.e., upright) with the first portion R1 installed on the left side and the second portion R2 installed on the right side; Figures 5 to 8 As shown, when applied to a right-hand drive vehicle, the sun visor body 11 is installed and fixed in a layout manner (i.e. reverse installation) with the first portion R1 installed on the right side and the second portion R2 installed on the left side. Thus, the same sun visor 10 can be adapted to different vehicles by different installation methods, without the need to manufacture different sun visors through different molds, effectively reducing the production cost.

[0049] like Figure 2 and Figure 6 As shown, as an practicable manner, the height difference between the first portion R1 and the second portion R2 is Δ The value range of h is 0.5mm~2.5mm to meet the regulatory requirements for the shape of the light and dark cut-off line.

[0050] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 , Fig.11 , Figures 13 to 16 As shown, as an implementable manner, the mounting structure 110 is provided with an anti-error structure for installation error prevention, and the number of the anti-error structure is at least one. For example, the anti-error structure is an anti-error hole 113, and in this embodiment, the number of the anti-error holes 113 is two.

[0051] In the actual installation process, the layout orientation of the anti-mistake hole 113 can be made consistent with the layout orientation of the driving seat of the vehicle, for example, Figure 1 , Figure 3 , Fig. 9 , Figures 13 to 16 As shown, when the driving position of the vehicle is on the left side (i.e., a left-hand drive vehicle), the fixed sunshade 10 should be installed in a layout manner in which the anti-misalignment hole 113 is installed on the left side of the headlight optical system 100; Figure 5 , Figure 7 and Fig.11 As shown, when the driving position of the vehicle is on the right side (ie, a right-hand drive vehicle), the fixed sunshade 10 should be installed in a layout manner in which the anti-misalignment hole 113 is installed on the right side of the headlight optical system 100 .

[0052] In other embodiments, the error-proofing structure can also be other error-proofing marks, so as to select different layouts for installing the fixed sunshade 10 corresponding to left-hand drive vehicles and right-hand drive vehicles. For example, the error-proofing mark can be text (such as left, right, front, back), letters (such as L, R), arrows with directions (such as ←, →), etc. In addition, the error-proofing structure can also be a structure such as a positioning column.

[0053] As an implementable method, the surface of the sunshade body 11 is set as a reflective surface. Specifically, the light emitted by the light source is converged by the primary optical element 20, and then cut off by the sunshade 10 and emitted by the light emitting element 30 to form a light-emitting light pattern, wherein part of the light is reflected when reaching the surface of the sunshade body 11, and the reflected light can be emitted through the light emitting element 30 and form a light-emitting light pattern together with other light that is also emitted through the light emitting element 30. Since the sunshade 10 is set in the light path, when the light passes through the sunshade 10, some light will hit the surface of the sunshade body 11. In order to improve the light effect of the light-emitting light pattern, this part of the light can be used, so the surface of the sunshade body 11 is set as a reflective surface, and the reflective surface can be an aluminum-plated surface or a pattern can be set to reflect the light, and the reflected light can be emitted through the light emitting element 30.

[0054] Furthermore, if Fig.16 As shown, as an implementable manner, a convex point 114 close to the cut-off line structure 112 is provided on the reflective surface to block the light at the regulatory test point corresponding to 50L or 50R in the light emission light pattern through the convex point 114; when applied to a left-hand drive vehicle, the regulatory test point corresponding to the convex point 114 located close to the cut-off line structure 112 is 50L, so as to meet the regulatory requirements for 50L in the light emission light pattern; when applied to a right-hand drive vehicle, the regulatory test point corresponding to the convex point 114 located close to the cut-off line structure 112 is 50R, so as to meet the regulatory requirements for 50R in the light emission light pattern.

[0055] As an implementable manner, the primary optical element 20 is a condenser, and the light emitting element 30 is a lens. Of course, the primary optical element 20 is not limited to a condenser, and other optical elements such as a reflector can also be used, and the light emitting element 30 is not limited to a lens, and other optical elements such as a reflector can also be used.

[0056] The embodiment of the present application further provides a vehicle light optical system 100, comprising the above-mentioned sunshade 10. Since the structure and beneficial effects of the sunshade 10 have been described in detail in the above-mentioned embodiment, they will not be described again here.

[0057] The embodiment of the present application further provides a vehicle, comprising the above-mentioned vehicle light optical system 100. Since the structure and beneficial effects of the vehicle light optical system 100 have been described in detail in the above-mentioned embodiment, they will not be described again here.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
