[0038] The embodiments in the present application will be described below in detail with the accompanying drawings of the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments in the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.
[0039] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with the accompanying drawings and specific embodiments.
[0040] As described in the background section, in the current optical design of vehicle lamps, the pattern modeling of vehicle lamp products is single, the pattern recognition degree of the vehicle lamp in the unlit state is poor, and there is no novelty, and the vehicle lamp in the lit state can only present a plane effect similar to surface light emission, lacking a three-dimensional sense, and cannot meet the current differentiated and personalized demands for vehicle lamps.
[0041] Based on the above, the present application provides an outer lens applied to a vehicle lamp module. As shown in Figure 1 is a structural schematic diagram of an outer lens provided by the present application, which comprises: Figure 1
[0042] A lens body 100, the lens body 100 comprises a first surface 110 and a second surface 120, the first surface 110 is the light entrance surface of the outer lens, and the second surface 120 is the light exit surface of the outer lens, the vehicle lamp beam enters the outer lens through the first surface 110 and exits from the second surface 120.
[0043] A pattern unit 200, the pattern unit 200 is located on the side of the second surface 120 away from the first surface 110, that is, the pattern unit 200 is located on the light exit side of the second surface 120. As Figure 2 As shown, the pattern unit 200 includes a plurality of pattern structures 210, the pattern structure 210 is a table-shaped structure protruding relative to the second surface 120, and the pattern structure 210 has a plurality of light emitting surfaces 211, the light emitting directions of the plurality of light emitting surfaces 211 are different, that is, the light emitting directions of the vehicle lamp light beam emitted through the plurality of light emitting surfaces 211 are different. It should be noted that the above-mentioned pattern unit 200 covers at least part of the second surface 120, that is, the pattern unit 200 can cover part of the second surface 120, or can cover the entire second surface 120, which is not limited in the present application, and is determined according to the situation.
[0044] As can be seen from the above, the light emitting surface of the outer lens is provided with a pattern of table-shaped structure, and the pattern structure 210 has a plurality of light emitting surfaces with different light emitting directions. Based on this, when the vehicle lamp is lit, the vehicle lamp light beam can be emitted from different directions by the pattern structure 210, that is, the pattern structure 210 can diffuse the vehicle lamp light beam to different angles, so that the vehicle lamp can present a dazzling lighting effect when lit. Again, since the pattern structure 210 is a table-shaped structure protruding relative to the second surface 120, when the vehicle lamp light beam is emitted from the pattern structure 210, a three-dimensional dazzling lighting effect can be presented. Similarly, when the vehicle lamp is in a non-lighting state, the light beam in the environment where the vehicle lamp is located is incident on the pattern structure 210 and will also be diffused to different angles by the pattern structure 210, thereby presenting a three-dimensional dazzling effect. As can be seen, the outer lens provided by the present application can make the vehicle lamp present a three-dimensional dazzling effect in the lighting state and the non-lighting state, and has strong recognition, which is helpful to meet the current differentiated and personalized demands of vehicle lamps, and has a wide application prospect.
[0045] In an embodiment of the present application, the shapes and sizes of the plurality of pattern structures 210 are the same, that is, the pattern structures 210 located on the light emitting side of the second surface 120 can be completely the same, which simplifies the preparation difficulty of the pattern unit 200, and at the same time makes the appearance of the second surface 120 with pattern structures consistent everywhere, thereby making the watchability of the appearance of the vehicle lamp strong.
[0046] Based on the foregoing embodiment, in an embodiment of the present application, as Figure 2 shown, the plurality of light emitting surfaces of the pattern structure 210 include a first light emitting surface 211 and a second light emitting surface 212, wherein the first light emitting surface 211 is the top surface of the pattern structure 210, and the second light emitting surface 212 is the side surface of the pattern structure 210, that is, the first light emitting surface 211 is the table surface of the table-shaped structure of the pattern structure 210, and the second light emitting surface 212 is the side surface of the table-shaped structure of the pattern structure 210.
[0047] The second light-exit surface 212 is on the side of the first light-exit surface 211 facing the second surface 120, surrounds the first light-exit surface 211, and extends outward of the first light-exit surface 211. The second light-exit surface 212 has a preset included angle with the first light-exit surface 211, and the value of the preset included angle is 0-90°, not including the end point value. That is, the pattern structure 210 is a table-shaped structure that gradually narrows in the convex direction thereof. That is, the second light-exit surface 212 of the pattern structure 210 is an inclined surface that inclines outward of the first light-exit surface 211. That is, the side surface of the table-shaped structure of the pattern structure 210 is an inclined surface that inclines outward of the top surface. Thus, the light-exit direction of the second light-exit surface 212 of the pattern structure 210 is different from the light-exit direction of the first light-exit surface 211. Therefore, the pattern structure 210 can diffuse the light beam irradiated thereon to different directions, so as to achieve the sparkling effect in the light-on state and the light-off state of the vehicle lamp. Moreover, the second light-exit surface 212 of the pattern structure 210 is an inclined surface that inclines outward of the first light-exit surface 211. Thus, the light beam of the second light-exit surface 212 can diffuse outward of the first light-exit surface 211. Therefore, the light beam diffusion angle of the pattern structure 210 is larger, the light-exit surface of the outer lens is larger, and thus the light-exit surface of the vehicle lamp is larger, which is helpful to achieve a larger light-exit surface of the vehicle lamp.
[0048] In an embodiment of the present application, as shown in Figure 3 The first light-exit surface 211 includes at least one first sub light-exit surface 2111, and the shape of the first sub light-exit surface 2111 is the same as that of the first light-exit surface 211. As shown in Figure 4 The first sub light-exit surface 2111 is a plane, and the light-exit directions of the first sub light-exit surface 2111 are different. In addition, the included angle between the light-exit direction of the first sub light-exit surface 2111 and the first direction is a first included angle, the included angle between the light-exit direction of the first portion 121 of the second surface 120 and the first direction is a second included angle, and the first included angle is greater than the second included angle. The first portion 121 is the portion of the second surface 120 corresponding to the first sub light-exit surface 2111, and the first direction is parallel to the optical axis of the outer lens.
[0049] Based on the above, the first sub-light-emitting surface 2111 is a plane, and the light-emitting directions of the first sub-light-emitting surfaces 2111 are different, that is, each of the first sub-light-emitting surfaces 2111 in the first light-emitting surface 211 is not in the same plane, so that the vehicle lamp light beams emitted from the first light-emitting surface 211 can be diffused to different directions, and the ambient light beams transmitted to the first light-emitting surface 211 can be reflected to different directions, thereby realizing the sparkling effect in the on and off states of the vehicle lamp. In addition, the angle between the light-emitting direction of the first sub-light-emitting surface 2111 and the first direction is greater than the angle between the light-emitting direction of the first part 121 and the first direction, and the first direction is parallel to the optical axis of the outer lens, that is, the light-emitting direction of the first sub-light-emitting surface 2111 is different from the light-emitting direction of the part of the second surface 120 corresponding to the first sub-light-emitting surface 2111, so that the light-emitting direction of the first light-emitting surface 211 of the pattern structure 210 is different from the light-emitting direction of the part of the second surface 120 corresponding to the first light-emitting surface 211, so that the first light-emitting surface 211 can change the emission direction of the vehicle lamp light beams when the vehicle lamp light beams are emitted from the second surface 120, thereby the emission direction of the vehicle lamp light beams can be adjusted through the first light-emitting surface 211, meeting the application requirements of different application scenarios, and having strong practicality.
[0050] In an embodiment of the present application, as shown in Figure 3 The second light-emitting surface 212 includes a plurality of second sub-light-emitting surfaces 2121, the second sub-light-emitting surfaces 2121 are planes, and the plurality of second sub-light-emitting surfaces 2121 are arranged in a direction around the first light-emitting surface 211, and the light-emitting directions of the plurality of second sub-light-emitting surfaces 2121 are different, so that the plurality of second sub-light-emitting surfaces, that is, each of the second sub-light-emitting surfaces 2121 in the second light-emitting surface 212 is not in the same plane, so that the vehicle lamp light beams emitted from the second light-emitting surface 212 can be diffused to different directions, and the ambient light beams transmitted to the second light-emitting surface 212 can be reflected to different directions, thereby realizing the sparkling effect in the on and off states of the vehicle lamp.
[0051] Based on the above, the first light-emitting surface 211 can include a plurality of first sub-light-emitting surfaces 2111, the plurality of first sub-light-emitting surfaces 2111 can be planes and have different light-emitting directions, the second light-emitting surface 212 can include a plurality of second sub-light-emitting surfaces 2121, and the plurality of second sub-light-emitting surfaces 2121 can be planes and have different light-emitting directions, so that when the vehicle lamp light beams are emitted from the pattern unit 200 or the ambient light beams are transmitted to the pattern unit 200, a sparkling effect similar to diamond light emission can be presented, the recognition degree is strong, which is helpful to meet the current differentiated and personalized demands of vehicle lamps, and the application prospect is wide.
[0052] In an embodiment of the present application, as shown in Figure 4As shown, the included angle between the light emitting direction of the second part 122 of the second surface 120 and the first direction is a fourth included angle, and the included angle between the light emitting direction of the second sub-light emitting surface 2121 and the first direction is a third included angle, and the third included angle is greater than the fourth included angle. As described above, the light emitting direction of the second light emitting surface 212 is different from the light emitting direction of the part of the second surface 120 corresponding to the second light emitting surface 212, so that the emission direction of the vehicle lamp beam can be changed when the vehicle lamp beam is emitted from the second surface 120, and the emission direction of the vehicle lamp beam can be adjusted through the second light emitting surface 212 to meet the application requirements of different application scenarios, which has strong practicability.
[0053] In an embodiment of the present application, the first light emitting surface 211 can include one first sub-light emitting surface 2111, that is, the first light emitting surface 211 can be composed of one first sub-light emitting surface 2111. The shape of the first sub-light emitting surface 2111 can be an N-sided polygon, N≥3. Correspondingly, the second light emitting surface 212 can include N second sub-light emitting surfaces 2121.
[0054] Based on the above, in a specific embodiment of the present application, as Figure 3 shown, the shape of the first sub-light emitting surface 2111 is a triangle, which is sequentially connected in a clockwise direction by a first side 1, a second side 2 and a third side 3, and the lengths of the first side 1, the second side 2 and the third side 3 are equal, so that the first sub-light emitting surface 2111 is an equilateral triangle, and the first light emitting surface 211 is also an equilateral triangle. It should be noted that, since the shape of the first sub-light emitting surface 2111 is the same as the shape of the first light emitting surface 211, and the shape of the first sub-light emitting surface 2111 is a triangle, the first light emitting surface 211 is composed of the first sub-light emitting surface 2111 which is a triangle, for example, the first light emitting surface 211 can be a triangular light emitting surface composed of one first sub-light emitting surface 2111, or a triangular light emitting surface composed of three first sub-light emitting surfaces 2111, or a triangular light emitting surface composed of six first sub-light emitting surfaces 2111, etc. The number of the first sub-light emitting surface 2111 in the first light emitting surface 211 is not limited in the present application, and is determined according to the situation. It should be further noted that, when the first light emitting surface 211 includes a plurality of first sub-light emitting surfaces 2111, the sizes and shapes of the first sub-light emitting surfaces 2111 can be the same, so that the shape of the first light emitting surface 211 is a regular shape, and the preparation process is relatively low in difficulty.
[0055] Correspondingly, as Figure 5 shown, the second light emitting surface 212 includes three second sub-light emitting surfaces 2121, which are sequentially arranged in a clockwise direction around the first light emitting surface 211, and the shape of the second sub-light emitting surface 2121 is a hexagon, and the shapes and sizes of the three second sub-light emitting surfaces 2121 are the same.
[0056] Based on the above, the second light output surface 212 includes three second sub-light output surfaces 2121 arranged in sequence clockwise in a direction around the first light output surface 211, and the shape of the second sub-light output surface 2121 is a hexagon, and the shape and size of the three second sub-light output surfaces 2121 are the same.
[0057] For the second light output surface 212, the three second sub-light output surfaces 2121 can be the third sub-light output surface 2121-1, the fourth sub-light output surface 2121-2, and the fifth sub-light output surface 2121-3, respectively. Among them, the third sub-light output surface 2121-1 is sequentially connected clockwise by the fourth edge 4, the fifth edge 5, the sixth edge 6, the seventh edge 7, the eighth edge 8, and the ninth edge 9, and the fourth edge 4, the fifth edge 5, the sixth edge 6, the seventh edge 7, the eighth edge 8, and the ninth edge 9 are equal in length. The fourth edge 4 is also equal in length to the first edge 1, and the first edge 1 coincides with the fourth edge 4, that is, the first light output surface 211 and the third sub-light output surface 2121-1 are connected by the coincidence of the first edge 1 and the fourth edge 4. In addition, the angle between the fourth edge 4 and the fifth edge 5 is the fifth angle α, and the angle between the fourth edge 4 and the ninth edge 9 is also the fifth angle α.
[0058] The fourth sub-light output surface 2121-2 is sequentially connected clockwise by the tenth edge 10, the eleventh edge 11, the twelfth edge 12, the thirteenth edge 13, the fourteenth edge 14, and the fifteenth edge 15, and the tenth edge 10, the eleventh edge 11, the twelfth edge 12, the thirteenth edge 13, the fourteenth edge 14, and the fifteenth edge 15 are equal in length. The tenth edge 10 is also equal in length to the second edge 2, and the tenth edge 10 coincides with the second edge 2, and the eleventh edge 11 coincides with the ninth edge 9, that is, the fourth sub-light output surface 2121-2 and the first light output surface 211 are connected by the coincidence of the tenth edge 10 and the second edge 2, and the fourth sub-light output surface 2121-2 is also connected to the third sub-light output surface 2121-1 by the coincidence of the eleventh edge 11 and the ninth edge 9. In addition, the angle between the tenth edge 10 and the eleventh edge 11 is the sixth angle α, the angle between the tenth edge 10 and the fifteenth edge 15 is also the sixth angle α, and the sixth angle is equal to the fifth angle.
[0059] The fifth sub-light-emitting face 2121-3 is sequentially connected in a clockwise direction by the sixteenth edge 16, the seventeenth edge 17, the eighteenth edge 18, the nineteenth edge 19, the twentieth edge 20 and the twenty-first edge 21, the lengths of the sixteenth edge 16, the seventeenth edge 17, the eighteenth edge 18, the nineteenth edge 19, the twentieth edge 20 and the twenty-first edge 21 are equal, and the length of the sixteenth edge 16 is also equal to the length of the third edge 3. The sixteenth edge 16 coincides with the third edge 3, the seventeenth edge 17 coincides with the fifteenth edge 15, and the twenty-first edge 21 coincides with the fifth edge 5, that is, the fifth sub-light-emitting face 2121-3 is connected to the first light-emitting face 211 through the coincidence of the sixteenth edge 16 and the third edge 3, and the fifth sub-light-emitting face 2121-3 is also connected to the third sub-light-emitting face 2121-1 through the coincidence of the twenty-first edge 21 and the fifth edge 5. In addition, the angle between the sixteenth edge 16 and the seventeenth edge 17 is a seventh angle α, the angle between the sixteenth edge 16 and the twenty-first edge 21 is also the seventh angle α, and the seventh angle is equal to the fifth angle.
[0060] Based on the above, the pattern structure 210 can include four edges, each of which is not in the same plane, and the top face of the four edges is an equilateral triangle, and the three side faces are hexagons of the same shape and size, and the length of the triangular edge of the first light-emitting face 211 is equal to the length of the hexagonal edge of the second sub-light-emitting face 2121, so that the pattern structure 210 realizes the sparkling effect, and the modeling rule of the pattern structure helps to simplify the preparation process of the pattern structure 210.
[0061] In an embodiment of the present application, the angle between the third sub-light-emitting face 2121-1 and the first light-emitting face 211 is an eighth angle, the angle between the fourth sub-light-emitting face 2121-2 and the first light-emitting face 211 is a ninth angle, the angle between the fifth sub-light-emitting face 2121-3 and the first light-emitting face 211 is a tenth angle, and the eighth angle, the ninth angle and the tenth angle are equal, that is, the angles between the top face of the pattern structure 210 and each of the surrounding side faces are equal, so that the modeling rule of the pattern structure helps to further simplify the preparation process of the pattern structure 210. And the angles between the top face of the pattern structure 210 and each of the surrounding side faces are equal, which can also make the angles between the light-emitting directions of each second sub-light-emitting face 2121 in the second light-emitting face 212 of the pattern structure 210 and the light-emitting direction of the first light-emitting face 211 the same, and then make the pattern structure 210 present a sparkling effect with similar side brightness, compared with the related art, avoiding the problem of large difference in brightness at different angles of the outer lens, and improving the lighting effect of the vehicle lamp.
[0062] In an embodiment of the present application, as Figure 6As shown, the plurality of pattern structures 210 arranged in an array on the side of the second surface 120 away from the first surface 110 can include at least one pattern structure 210 in the second direction and at least one pattern structure 210 in the third direction, the second direction and the third direction being parallel to the second surface and perpendicular to each other.
[0063] Wherein, the at least one pattern structure 210 in the second direction is located on the same straight line, and the mth pattern structure 210 and the m+1th pattern structure 210 are connected and expose part of the second surface 120, m≥1.
[0064] The nth pattern structure 210 and the n+2th pattern structure 210 in the at least one pattern structure 210 in the third direction are located on the same straight line, and the nth pattern structure 210 and the n+1th pattern structure 210 are connected and expose part of the second surface 120, n≥1. It should be noted that the at least one pattern structure 210 in the second direction is located on the same straight line, which means that the center of the pattern structure 210 in the second direction, i.e. the center of the first light-emitting surface 211, is located on the same straight line. The nth pattern structure 210 and the n+2th pattern structure 210 in the at least one pattern structure 210 in the third direction are located on the same straight line, which means that the center of the first light-emitting surface 211 of the nth pattern structure and the center of the first light-emitting surface 211 of the n+2th pattern structure are located on the same straight line.
[0065] As can be seen from the above, the pattern structure 210 on the second surface 120 can also expose part of the second surface 120. Since the light-emitting direction of the second light-emitting surface 212 is different from the light-emitting direction of each light-emitting surface of the pattern structure 210, the vehicle lamp beam emitted from the second light-emitting surface 212 can be diffused to more directions, and the ambient light beam transmitted to the second light-emitting surface 212 can be reflected to more directions, thereby realizing the sparkling effect in the vehicle lamp lighting state and the non-lighting state.
[0066] In order to more clearly understand the above outer lens, the construction process of the pattern structure on the outer lens is described below.
[0067] As shown in Figure 7 A curved surface A1 is defined, which is usually obtained by vehicle lamp modeling design, and the pattern structure 210 needs to be designed on the surface of the curved surface A1, which is the light-emitting side of the second surface 120 of the above outer lens. A series of curves parallel to the boundary line are made on the curved surface A1, the base points between adjacent curves are arranged at equal intervals, and the base points are defined from the series of curves.
[0068] A base point S1 is taken on the curved surface A1, and two base points S2 and S3 in a triangle with the base point S1 are taken on an adjacent curve, and the base points S2 and S3 are located on the same curve. The curved surface A1 is offset by different distances along a direction perpendicular to the curved surface A1 to obtain the curved surfaces A2 and A3, and the base points S2 and S3 are respectively projected vertically onto the curved surfaces A2 and A3, at this time, the base points S1, S2 and S3 are located in different planes, and the base points S1, S2 and S3 are sequentially connected to obtain a closed triangular surface, the closed triangular surface is a regular triangle, and is the first light-out surface 211. Then, the base points S1, S2 and S3 are taken as starting points to extend in different directions by the same distance, the included angle between the line segment Li (i=1, 2, 3) and the base point Si (i=1, 2, 3) is α, and the length of the line segment Li (i=1, 2, 3) is equal to the length of the side of the triangular surface. The curved surface A3 is offset by a certain distance along the direction perpendicular to the curved surface A1 to obtain the curved surface A4, and the endpoints of the line segments Li (i=1, 2, 3) are projected vertically onto the curved surface A4 to obtain the points Pi (i=1, 2, 3); the points Pi (i=1, 2, 3) are taken as starting points to extend in different directions by two line segments Li1 (i=1, 2, 3) and Li2 (i=1, 2, 3) with the same distance, the included angle between the line segment Li1 (i=1, 2, 3) and the starting point Pi (i=1, 2, 3) is β, and the included angle between the line segment Li2 (i=1, 2, 3) and the starting point Pi (i=1, 2, 3) is also β. The curved surface A4 is offset by a certain distance along the direction perpendicular to the curved surface A1 to obtain the curved surface A5; the other end points of the line segments Li1 (i=1, 2, 3) and Li2 (i=1, 2, 3) are projected vertically onto the curved surface A5 to obtain the points Pi1 (i=1, 2, 3) and Pi2 (i=1, 2, 3), and the points Pi1 (i=1, 2, 3) and Pi2 (i=1, 2, 3) on the curved surface A5 are sequentially connected to obtain three closed hexagonal surfaces, and the above-mentioned triangular surface and the three hexagonal surfaces are combined together to obtain a pattern unit, as shown in Figure 8 It should be noted that, referring to Figure 8 , the point S1 is located on the curved surface A1, the point S2 is located on the curved surface A2, the point S3 is located on the curved surface A3, the points P1, P2 and P3 are located on the curved surface A4, and the points P11, P12, P21, P22, P31 and P32 are located on the curved surface A5.
[0069] Based on the above, when the pattern structure is constructed, the size of the pattern structure can be adjusted by changing the distance between the base points S, the angle between the line segments Li (i = 1, 2, 3) and the base points Si (i = 1, 2, 3) is α, and the angle between the line segments Li1 (i = 1, 2, 3) and the starting points Pi (i = 1, 2, 3) is β and the angle between the line segments Li2 (i = 1, 2, 3) and the starting points Pi (i = 1, 2, 3) is β. When the pattern structure is constructed, the inclination of each light-emitting surface of the pattern structure can be adjusted by changing the offset distance of the curved surface S1, the curved surface S2, the curved surface S3, the curved surface S4 and the curved surface S5, and then the light-emitting direction of each light-emitting surface of the pattern structure is adjusted, and then different lighting effects are obtained, and the lighting uniformity of each light-emitting surface of the pattern structure is improved, so as to realize the light distribution requirement of different application scenarios, and the practicability is stronger
[0070] Correspondingly, the application also provides a vehicle lamp module, which comprises the outer lens described in any one of the above embodiments.
[0071] In summary, the application provides an outer lens and a vehicle lamp module. The outer lens comprises a lens body and a pattern unit.
