For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. It should be noted that the longitudinal section line is the section line obtained by the vertical plane perpendicular to the vertical tangent plane of the first light exit surface 12.

[0080] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features, therefore, the features limited by "first", "second" can be explicitly or implicitly include one or more of the features.

[0081] It should be understood that in order to facilitate the description of the present application and simplify the description, the terms "front", "back" refer to the front and back directions of the vehicle lamp optical unit along the light emitting direction, i.e. the first light exit surface 12 is located in front, the light receiving structure reference surface 11 is located in the rear, the terms "left, right" refer to the left and right directions of the vehicle lamp optical unit along the light emitting direction, and the terms "up, down" refer to the up and down directions of the vehicle lamp optical unit along the light emitting direction. The terms are based on the orientation or positional relationship shown in the drawings, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0082] The first aspect of the present application provides a vehicle lamp optical unit, referring to Figures 1 to 15 、 Figure 17 、 Figure 19 、 Figures 24 to 26 , comprising a first optical element 1, the rear end surface and the front end surface of the first optical element 1 along the light emitting direction are respectively a light receiving structure reference surface 11 and a first light exit surface 12, the rear end of the first optical element 1 is formed into a light receiving part, the light receiving part comprises at least one first light receiving structure arranged along the left and right directions of the light receiving structure reference surface 11, and a first light channel 13 is formed between the light receiving part and the first light exit surface 12; wherein the first light receiving structure is arranged to extend from the upper side or the lower side of the light receiving structure reference surface 11 to the first light channel 13, and each first light receiving structure can guide the light received by the first light receiving structure to exit towards the first light channel 13 and transmit along the first light channel 13 to the first light exit surface 12.

[0083] Through the vehicle lamp optical unit of the above-mentioned basic technical solution of the present invention, the light received by the first light-incident structure is deflected from the upper or lower side of the light-incident structure reference surface 11 and emitted toward the first light channel 13, and transmitted along the first light channel 13 to the first light-emitting surface 12, and then emitted from the first light-emitting surface 12 to form the required illumination light pattern. This can effectively avoid the generation of light spots when the light source corresponding to the first light-incident structure (i.e., the light source 4 mentioned below) is located behind the first optical element 1, and avoid the appearance of a row of light spots when the vehicle lamp is lit in front of the headlight, thus improving the appearance and visual effect of the vehicle lamp optical unit. At the same time, the vehicle lamp optical unit can meet the needs of various vehicle lamp lighting modes and illumination modes.

[0084] As a preferred embodiment of the present invention, see [link to previous document]. Figures 1 to 15 , Figure 17 , Figure 19 , Figure 24 to Figure 26 Each first light-incident structure includes a condenser 113 located above or below the light-incident structure reference surface 11 and a light guide 114 connected to the condenser 113. The light guide 114 extends from the light-emitting end of the condenser 113 to the rear end of the first light channel 13. The light guide 114 is provided with a reflective part 115, which can reflect the emitted light from the condenser 113 toward the first light channel 13. The condenser 113 can be constructed using various light-concentrating elements. For example, it can be specifically configured as a condenser cup with a recessed light source connection portion. Correspondingly, the opening of the light source connection portion faces upward or downward. The reflector 115 can be specifically configured as a reflective plane or reflective curved surface with a certain tilt angle opposite to the light-emitting end of the concentrator 113. That is, the light received by the concentrator 113 is emitted to the reflector 115, reflected by the reflector 115 and emitted toward the first light channel 13, and transmitted to the first light-emitting surface 12 through the first light channel 13.

[0085] In this invention, in order to better utilize the automotive lamp optical unit to form various automotive lamp patterns, preferably, the connection between the first light channel 13 and each light guide 114 is provided with a groove structure 131 corresponding to the light guide 114, see [link to relevant documentation]. Figure 10 and Figure 11 , Figure 13 and Figure 14Each groove structure 131 comprises a light guide portion connecting surface 132 connected with the light guide portion 114 corresponding to the groove structure 131, an intermediate connecting surface 133 connected with the light guide portion connecting surface 132, and a light channel connecting surface 134 connected with the intermediate connecting surface 133; wherein the connection between the intermediate connecting surface 133 and the light channel connecting surface 134 is provided with a first cut-off portion 135 forming a first light shape cut-off line. At this time, the first light shape cut-off line formed by the first cut-off portion 135 can be designed according to the specific application of the first optical element 1, for example, it can be an auxiliary low beam cut-off line, or an auxiliary high beam cut-off line.

[0086] In the present application, the first light exit surface 12 is preferably a forward convex curved surface, which can be designed as a single, smooth curved light exit surface to improve the appearance of the vehicle lamp. Correspondingly preferably, referring to Figure 4 The first cut-off portion 135 is located on the intermediate surface of the first light exit surface 12, and the intermediate surface is a horizontal surface passing through the vertex of the longitudinal section line of the first light exit surface 12, so that the first light shape cut-off line corresponding to the first cut-off portion 135 is clearer and the light shape is better.

[0087] Further preferably, the first light exit surface 12 is a curved surface with continuous curvature, which improves the appearance and light exit effect of the first optical element 1.

[0088] The at least one first light entry structure of the present application can be designed as at least one low beam first light entry structure 111, or at least one high beam first light entry structure 112, or at least one low beam first light entry structure 111 and at least one high beam first light entry structure 112. The number of low beam first light entry structures 111 and / or high beam first light entry structures 112 can be one, two, three or more, which can be set according to the actual application requirements of the vehicle lamp optical unit.

[0089] In order to simplify the structural design of the vehicle lamp optical unit, reduce the positioning and installation errors between various vehicle lamp lighting units and parts, and improve the installation precision, the projection of the first light exit surface 12 and the light entry structure reference surface 11 along the light exit direction is in the shape of a left and right extending strip, the first light entry structure is designed as a plurality of low beam first light entry structures 111 and a plurality of high beam first light entry structures 112, the low beam first light entry structures 111 and the high beam first light entry structures 112 are arranged alternately, and each condenser 113 is located on the lower side of the light entry structure reference surface 11. At this time, the first optical element 1 can be used to form part of the light shape or the complete light shape of the low beam or the high beam, integrating multiple functions into one, and the structure is simple and compact. The low beam first light entry structures 111 and the high beam first light entry structures 112 are arranged alternately, which can ensure that the lighting effect of the first light exit surface 12 is consistent in the low beam and high beam modes, avoiding the situation that only part of the first light exit surface 12 is lit in the single low beam mode, which affects the lighting effect of the vehicle lamp.

[0090] On the basis that the low beam first light entry structure 111 and the high beam first light entry structure 112 are arranged alternately, the distance between the first cutoff portion 135 corresponding to the low beam first light entry structure 111 and the upper surface of the first light channel 13 is greater than the distance between the first cutoff portion 135 corresponding to the high beam first light entry structure 112 and the upper surface of the first light channel 13, that is, the first cutoff portion 135 corresponding to the high beam first light entry structure 112 is higher than the first cutoff portion 135 corresponding to the low beam first light entry structure 111, so that there is a step between the first cutoff portion 135 corresponding to the low beam first light entry structure 111 and the first cutoff portion 135 corresponding to the high beam first light entry structure 112. The step between the first cutoff portion 135 corresponding to the low beam first light entry structure 111 and the first cutoff portion 135 corresponding to the high beam first light entry structure 112 makes the high beam light shape and the low beam light shape have a certain overlap, that is, the cutoff line of the high beam light shape is located below the cutoff line of the low beam light shape, and thus the connection effect of the low beam and the high beam is better.

[0091] Further specifically, the intermediate connecting surface 133 corresponding to the low beam first light entry structure 111 is arranged to be inclined upward from back to front, and the side of the intermediate connecting surface 133 facing the first light channel 13 is provided as a reflecting surface; the intermediate connecting surface 133 corresponding to the high beam first light entry structure 112 is arranged to be inclined downward from back to front, and the side of the intermediate connecting surface 133 away from the first light channel 13 is also provided as a reflecting surface. Referring to FIG. 11, the light received by the low beam first light entry structure 111 is changed in direction by the light guide portion 114 and emitted toward the first light channel 13, most of the light is directly transmitted to the first light exit surface 12 after being cut off by the first cutoff portion 135 corresponding to the first light channel 13, and a small part of the light is reflected by the intermediate connecting surface 133 corresponding to the first light channel 13 to the first light channel 13 for further transmission, so as to improve the light efficiency, and the two parts of light are emitted through the first light exit surface 12 to form a light shape with an auxiliary low beam cutoff line; referring to FIG. 12, the light received by the high beam first light entry structure 112 is changed in direction by the light guide portion 114 and emitted from the light guide portion connecting surface 132 corresponding to the high beam first light entry structure 112, most of the light is directly transmitted to the first light exit surface 12 after being cut off by the first cutoff portion 135 corresponding to the first light channel 13, and a small part of the light is reflected by the intermediate connecting surface 133 corresponding to the first light channel 13 to the light channel connecting surface 134 corresponding to the first light channel 13 for further transmission, so as to improve the light efficiency, and the two parts of light are emitted through the first light exit surface 12 to form a light shape with an auxiliary high beam cutoff line. Figure 12

[0092] ​On the basis of the above-mentioned first optical element of the present application, referring to Figures 15 to 26 the vehicle lamp optical unit further comprises a second optical element 2, one side of the first optical element 1 in the left-right direction is formed with a notch for accommodating the second optical element 2, the rear end face and the front end face of the second optical element 2 along the light-emitting direction are respectively the light-incident face 21 and the second light-emitting face 22, at least one second light-incident structure is arranged on the light-incident face 21, and the second optical element 2 is arranged to be capable of guiding the light emitted by the second light-emitting face 22 to be emitted via the first light-emitting face 12. The first optical element 1 and the second optical element 2 share the first light-emitting face 12, which is more conducive to the light shape matching of the two, so that the vehicle lamp optical unit forms the required vehicle lamp light shape.

[0093] In order to enable the part of the first optical element 1 corresponding to the second optical element 2 to form a single focal point in front of it, for forming a main low beam cutoff line with an inflection point, preferably, the first optical element 1 is provided with a secondary light-incident face 14, which is located behind the first light-emitting face 12 and faces the notch, and the secondary light-incident face 14 comprises at least one rearward convex curved surface.

[0094] As a preferred embodiment of the second optical element 2, a plurality of second light-incident structures are arranged on the light-incident face 21, and the plurality of second light-incident structures are arranged to have at least one low beam second light-incident structure 211 and at least one high beam second light-incident structure 212. The specific number of the low beam second light-incident structure 211 and the high beam second light-incident structure 212 is set according to the requirement of the light shape formed by the second optical element 2, and at the same time, the two are preferably integrally formed, which improves the installation accuracy of the vehicle lamp optical unit.

[0095] Preferably, each low beam second light-incident structure 211 and each high beam second light-incident structure 212 is a condensing structure. The condensing structure can be a condensing cup or other condensing element to improve the light efficiency.

[0096] Specifically, referring to Figure 20 and Figure 21 , the low beam second light-incident structure 211 is located above the high beam second light-incident structure 212, the second light-emitting face 22 comprises a low beam light-emitting face 221 located in front of the low beam second light-incident structure 211 and a high beam light-emitting face 222 located at the light-emitting end of the high beam second light-incident structure 212, a second light channel 23 is arranged between the light-emitting end of the low beam second light-incident structure 211 and the low beam light-emitting face 221, and a second cutoff portion 24 for forming a second light shape cutoff line is arranged at the connection between the bottom surface of the second light channel 23 and the low beam light-emitting face 221. The second light shape cutoff line can be a main low beam cutoff line, or a main high beam cutoff line. At this time, referring to Figure 22The light rays received by the second low-beam light-receiving structure 211 are emitted to the second light channel 23, transmitted to the low-beam light-emitting surface 221 through the second light channel 23, and form a light shape with a main low-beam cutoff line by the second cutoff portion 24; and the light rays received by the second high-beam light-receiving structure 212 are directly emitted from the high-beam light-emitting surface 222 and form a light shape with a main high-beam cutoff line by the second cutoff portion 24.

[0097] Further preferably, the lower surface of the second light channel 23 is provided as a reflective surface. When part of the light rays emitted by the second low-beam light-receiving structure 211 to the second light channel 23 are incident on the lower surface of the second light channel 23, they are reflected by the reflective surface to continue transmitting in the second light channel 23; and when part of the light rays emitted by the high-beam light-emitting surface 222 are incident on the lower surface of the second light channel 23, they are reflected by the reflective surface to continue transmitting forward. Providing the lower surface of the second light channel 23 as a reflective surface can improve the light efficiency. Typically, the low-beam light-emitting surface 221 is provided as a forwardly convex curved surface, which can be a curved surface convex in the up-down direction, a curved surface convex in the left-right direction, or a curved surface convex in both the up-down direction and the left-right direction. This structure makes the light rays emitted by the low-beam light-emitting surface 221 more concentrated, so that more light rays are incident on the secondary light-receiving surface 14, further improving the light efficiency.

It should be noted that when the first optical element 1 is provided with the high-beam first light-receiving structure 112, the light guide 3 has a certain distance from the middle connecting surface 133 of the recess structure 131, so that the light rays emitted by the light-emitting surface of the high-beam first light-receiving structure 112 corresponding to the light channel connecting surface 134 can pass through and be incident on the light channel connecting surface 134. The minimum distance L between the two is set to ≤10 mm, preferably 1 mm≤L≤5 mm; when the first optical element 1 is only provided with the low-beam first light-receiving structure 111, the distance L can be set to 0.
