[0043] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation modes described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the specific implementation modes described below.
[0044] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation" and "connection" 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 direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] In the present utility model, unless otherwise specified, the directional words used, such as "above, below, left, right, front, and rear", generally refer to the positional relationship of the headlights during actual use. For example, when the headlights are set at the rear of a vehicle and emit light to the rear of the vehicle, the direction pointed by the front of the vehicle is the rear, and the direction pointed by the rear of the vehicle is the front, while "above", "below", "left", and "right" are positional relationships determined based on the positional relationship of "front" and "rear".
[0046] The basic implementation of the utility model provides an outer lens, such as Figure 1 and Figure 2 As shown, it includes a lens body 1, one side surface of the lens body 1 is formed as an outer lens light emitting surface 11, and the other side surface is formed with an outer lens high beam light incident surface 12 and an outer lens low beam light incident surface 13, and the height ratio of the outer lens high beam light incident surface 12 and the outer lens low beam light incident surface 13 is greater than or equal to 0.7 and less than 1, or greater than 1 and less than or equal to 1.3.
[0047] During actual use, the outer lens high beam incident surface 12 and the outer lens low beam incident surface 13 are arranged vertically, and the outer lens high beam incident surface 12 can be arranged above the outer lens low beam incident surface 13, or the outer lens high beam incident surface 12 can be arranged below the outer lens low beam incident surface 13, which is specifically determined according to the upper and lower positional relationship between the low beam light source and the high beam light source.
[0048] The outer lens provided by the above basic embodiment of the utility model is configured such that the outer lens high beam incident surface 12 and the outer lens low beam incident surface 13 are separately arranged, and the height ratio of the outer lens high beam incident surface 12 and the outer lens low beam incident surface 13 is controlled to be greater than or equal to 0.7 and less than 1, or greater than 1 and less than or equal to 1.3, and the light a emitted from the light source is emitted from the lens as much as possible (see Figure 8 ), and can ensure the light output light shape effect (see Fig. 9 ), which can improve the utilization rate of the outer lens while ensuring the light shaping effect. When the height ratio of the outer lens high beam light entrance surface 12 and the outer lens low beam light entrance surface 13 is 1:1, part of the light a is reasonably used by the outer lens after being refracted by the inner lens to form low beam light shapes and high beam light shapes; part of the light b is not reasonably used by the outer lens after being refracted by the inner lens, affecting the utilization rate of the light source.
[0049] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the outer lens high beam incident surface 12 and the outer lens low beam incident surface 13 are both curved surfaces that bulge outward from both ends to the middle area in the vertical direction z, and the focal length ratio of the outer lens high beam incident surface 12 and the outer lens low beam incident surface 13 in the vertical direction z is greater than or equal to 0.5 and less than or equal to 0.9. Through the above design, the light output effect of the outer lens can be further improved.
[0050] In another basic embodiment of the present invention, a lens module is provided, comprising an inner lens group and an outer lens as described in any of the above technical solutions. The lens module has all the advantages of the above lenses, which will not be described one by one here.
[0051] During actual use, the high beam light enters the lens body 1 from the high beam light incident surface 12 of the outer lens after passing through the inner lens group, and then is emitted from the outer lens light exit surface 11 to form a high beam light shape; the low beam light enters the lens body 1 from the low beam light incident surface 13 of the outer lens after passing through the inner lens group, and then is emitted from the outer lens light exit surface 11 to form a low beam light shape.
[0052] In a specific embodiment of the present invention, Figure 3-Figure 4As shown, the inner lens group includes a low beam inner lens 2 and a high beam inner lens 3. The low beam inner lens 2 is formed with a low beam inner lens light emitting surface 21 and at least one low beam inner lens light incident surface 22. The high beam inner lens 3 is formed with a high beam inner lens light emitting surface 31 and at least one high beam inner lens light incident surface 32.
[0053] During use, the number of high-beam inner lens light-entry surfaces 32 may be the same as the number of high-beam light sources, and the high-beam inner lens light-entry surfaces 32 are arranged correspondingly to the high-beam light sources, and the number of low-beam inner lens light-entry surfaces 22 may be the same as the number of low-beam light sources, and the low-beam inner lens light-entry surfaces 22 are arranged correspondingly to the low-beam light sources. The high-beam inner lens light-emitting surface 31 and the low-beam inner lens light-emitting surface 21 may each be provided with one.
[0054] When the lens module provided by the above-mentioned embodiment of the utility model is used, the high beam light enters the high beam inner lens 3 through the high beam inner lens light entrance surface 32, and then is emitted through the high beam inner lens light exit surface 31 and enters the lens body 1 through the outer lens high beam light entrance surface 12, and then is emitted through the outer lens light exit surface 11 to form the high beam light shape; the low beam light enters the low beam inner lens 2 through the low beam inner lens light entrance surface 22, and then is emitted through the low beam inner lens light exit surface 21 and enters the lens body 1 through the outer lens low beam light entrance surface 13, and is emitted through the outer lens light exit surface 11 to form the low beam light shape.
[0055] In a specific embodiment of the present invention, the distance between the focus of the outer lens high beam incident surface 12 and the focus of the high beam inner lens light exit surface 31 is less than or equal to 2 mm; the distance between the focus of the outer lens low beam incident surface 13 and the focus of the low beam inner lens light exit surface 21 is less than or equal to 2 mm. The distance between the high beam inner lens 3 and the outer lens high beam incident surface 12 can be made close to the distance between the low beam inner lens 2 and the outer lens low beam incident surface 13, thereby ensuring that the high beam inner lens 3 and the low beam inner lens 2 can be combined into one part, while reducing the number of parts and the module cost. Moreover, combining the high beam inner lens 3 and the low beam inner lens 2 into one part can ensure that there is still enough size for the radiator 7 under the condition of the front and rear size restrictions of the system, thereby ensuring the heat dissipation effect of the system.
[0056] In a specific embodiment of the present invention, the high-beam inner lens light-emitting surface 31 is an inner concave curved surface, and the low-beam inner lens light-emitting surface 21 is a flat surface or an outer convex curved surface.
[0057] According to the utility model, the light emitting surface 31 of the high beam inner lens is set as a concave curved surface, which means that the light emitting surface 31 of the high beam inner lens is a curved surface that is concave from the two sides or the four sides to the central area toward the inside of the high beam inner lens 3. The light emitting surface 21 of the low beam inner lens is set as a convex curved surface, which means that the light emitting surface 21 of the low beam inner lens is a curved surface that is convex from the two sides or the four sides to the central area toward the outside of the low beam inner lens 2. The concave curved surface of the light emitting surface 31 of the high beam inner lens can be a complete curved surface, or it can be a quasi-curved surface formed by splicing multiple planes and / or curved surfaces. The light emitting surface 21 of the low beam inner lens can be a complete plane or a convex curved surface, or it can be a quasi-plane or quasi-curved surface formed by splicing multiple curved surfaces and / or planes.
[0058] The lens module provided by the above embodiment of the utility model, by setting the high-beam inner lens light-emitting surface 31 of the high-beam inner lens 3 as an inner concave curved surface, can reduce the distance between the high-beam inner lens light-emitting surface 31 and the lens body 1 while ensuring that the focus of the high-beam inner lens light-emitting surface 31 is placed near the focus of the high-beam light-entering surface of the outer lens, thereby reducing the front and rear dimensions of the high-beam module while ensuring the high-beam effect, which is conducive to meeting the miniaturization requirements of the module. It can also increase the size of the radiator 7 at the high-beam light source, ensure the heat dissipation effect of the high-beam module, and extend the service life of the high-beam light source.
[0059] The low beam inner lens light exit surface 21 can be set as a plane or a convex curved surface. As a relatively preferred embodiment of the utility model, the low beam inner lens light exit surface 21 is a plane, which can reduce the front and rear dimensions of the low beam module while ensuring the low beam effect, further realizing the miniaturization demand of the module.
[0060] According to the present invention, the plane here refers to a plane or a quasi-plane.
[0061] The high-beam inner lens light entrance surface 32 of the high-beam inner lens 3 may be an external convex curved surface, and the low-beam inner lens light entrance surface 22 of the low-beam inner lens 2 may also be an external convex curved surface. The number of high-beam inner lens light entrance surfaces 32 and low-beam inner lens light entrance surfaces 22 may be determined according to actual conditions. When multiple high-beam inner lens light entrance surfaces 32 and low-beam inner lens light entrance surfaces 22 are provided, the surface shapes of the multiple high-beam inner lens light entrance surfaces 32 may be consistent or inconsistent; the surface shapes of the multiple low-beam inner lens light entrance surfaces 22 may be consistent or inconsistent.
[0062] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, the high beam inner lens light exit surface 31 is a curved surface that is concave from both ends to the middle in the vertical direction z. Setting the high beam inner lens light exit surface 31 as a curved surface that is concave from both ends to the middle in the vertical direction z can reduce the front and rear dimensions of the high beam module while achieving a better high and low beam connection effect.
[0063] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, the high-beam inner lens light-emitting surface 31 includes a splicing section, and the splicing section is a curved surface formed by splicing a plurality of splicing surfaces 311. The curved surface formed by splicing at least one curved surface section 312 is used as a light-emitting surface, which can achieve the effect of diffusing the high-beam light shape. Preferably, the high-beam inner lens light-emitting surface 31 may also include at least one curved surface section 312. In actual use, a curved surface section 312 is arranged on a side of the splicing section close to the low-beam inner lens light-emitting surface 21. The splicing section is arranged as a curved surface formed by splicing a plurality of splicing surfaces 311. At the same time, at least one curved surface section 312 is arranged, which can ensure the high-beam and low-beam connection effect while diffusing the high-beam light shape.
[0064] According to the present invention, the joint surface 111 can be a curved surface or a flat surface.
[0065] As a specific embodiment of the present invention, the width of the splicing surface 311 is greater than 0 mm and less than or equal to 1.5 mm. During the research process, it was found that controlling the splicing surface width to be greater than 0 mm and less than or equal to 1.5 mm can ensure the maximum value of the high beam without affecting the connection effect of the high and low beams.
[0066] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, there are two curved surface segments 312, and the two curved surface segments 312 are located on both sides of the splicing segment. Placing the curved surface segments 312 on both sides of the splicing segment can further improve the high beam effect while ensuring the connection effect of the high beam and the low beam, so that the light in the upper and lower areas of the high beam is more uniform, thereby making the brightness of the high beam light shape more uniform.
[0067] In a specific embodiment of the present invention, the ratio of the total width of the curved surface segment 312 to the width of the high beam inner lens light exit surface 31 is less than or equal to 0.5, preferably 0.2-0.5. Through the above arrangement, the brightness uniformity of the high beam light shape can be further improved while ensuring the high beam diffusion effect, and the high beam maximum value can also be ensured.
[0068] In a specific embodiment of the present invention, Figure 3 and Figure 5 As shown, at least one three-zone light shape forming structure 5 is disposed on the light emitting surface 21 of the low beam inner lens. The three-zone light shape forming structure 5 can be any structure capable of forming a three-zone light shape.
