For example, connection may refer to fixed connection, or detachable connection, or integrated connection; it may refer to direct connection, or indirect connection via an intermediate, or inner communication between two elements or interactive relationship between two elements. For a person ordinarily skilled in the art, the specific meanings of the above-mentioned terms in the present invention could be construed in accordance with specific circumstances. It shall further be clarified that a longitudinal transversal is a transversal obtained through interception of a first light emergent plane 12 by a vertical plane perpendicular to a vertical tangent plane of the first light emergent plane 12.

[0033] In addition, terms such as "first" and "second" are used merely for purpose of description, and cannot be construed as indicating or implying to have importance in relativity, or implicitly suggesting the number of the indicated technical feature. Therefore, a feature defined with a term "first" or "second" can explicitly or implicitly comprise one or more said feature.

[0034] It should be understood that in order to facilitate the description of the present invention and simplify the description, terms "front" and "rear" refer to the forward and backward directions of a vehicle lamp optical unit along a light emergent direction, that is to say, the first light emergent surface 12 is located in the front, and a light incident structure reference plane 11 is located in the rear; terms "left" and "right" refer to the left and right direction of the vehicle lamp optical unit along the light emergent direction; and terms "upper" and "lower" refer to the upward and downward directions of the vehicle lamp optical unit along the light emergent direction. The terms indicate orientation or position relationships shown based on the accompanying drawings, rather than indicating or implying that a specified device or element must have a certain orientation and be constructed and operated in a certain orientation, and therefore cannot be construed as limiting the present invention.

[0035] Referring to Figs. 1 to 15, Fig. 17, Fig. 19, and Figs. 24 to 26, a vehicle lamp optical unit provided in a first aspect of the present invention comprises a first optical element 1, wherein the rear end face and the front end face of the first optical element 1 along a light emergent direction are respectively a light incident structure reference plane 11 and a first light emergent surface 12, the rear end of the first optical element 1 is formed as a light incident portion, the light incident portion comprises at least one first light incident structure provided along the left and right direction of the light incident structure reference plane 11, and a first light passage 13 is formed between the light incident portion and the first light emergent surface 12, wherein the first light incident structure is configured to extend from the upper side or the lower side of the light incident structure reference plane 11 to the first light passage 13, each of the first light incident structures is capable of guiding light rays received by the first light incident structure to be emitted towards the first light passage 13 and be transmitted to the first light emergent surface 12 along the first light passage 13.

[0036] Through the vehicle lamp optical unit according to the above-mentioned basic technical solutions of the present invention, light rays received by the first light incident structure emerge towards the first light passage 13 after direction change from the upper side or the lower side of the light incident structure reference plane 11, and are transmitted to the first light emergent surface 12 along the first light passage 13, and in turn emerge from the first light emergent surface 12 and form a desired illumination light shape, wherein it can be effectively avoided that a light spot is produced when a light source (namely the light source 4 described below) corresponding to the first light incident structure is provided in the rear of the first optical element 1, and it is avoided that the vehicle lamp lightening effect shows, when viewing from the front of the vehicle lamp, a row of light spots, hereby improving the appearance visual effect of the vehicle lamp optical unit; moreover, the vehicle lamp optical unit can meet requirements for various vehicle lamp illumination modes and lightening modes.

[0037] As a preferred embodiment of the present invention, referring to Figs. 1 to 15, Fig. 17, Fig. 19, and Figs. 24 to 26, each of the first light incident structures respectively comprises a collimator 113 located on the upper side or the lower side of the light incident structure reference plane 11, and a light guide portion 114 in connection with the collimator 113; the light guide portion 114 extends from the light emergent end of the collimator 113 to the rear end of the first light passage 13; the light guide portion 114 is provided with a reflecting portion 115; and the reflecting portion 115 is capable of reflecting the emergent light of the collimator 113 to a direction towards the first light passage 13 for emergence. Various collimating elements may be adopted for the structure of the collimator 113. For example, it may be specifically configured as a collimating cup, which is provided with an inwardly recessed light source connection portion, and correspondingly, the opening of the light source connection portion faces up or faces down. The reflecting portion 115 may be specifically configured as a reflecting plane or a reflecting curved surface, which is opposite to the light emergent end of the collimator 113 and has a certain inclined angle, that is to say, light rays received by the collimator 113 are emitted to the reflecting portion 115, reflected by the reflecting portion 115 and then emitted towards the first light passage 13, and transmitted to the first light emergent surface 12 through the first light passage 13.

[0038] In the present invention, in order to enable the vehicle lamp optical unit to be better applied for forming various vehicle lamp light shapes, preferably, a recess structure 131 corresponding to the light guide portion 114 is respectively provided at the connection between the first light passage 13 and each of the light guide portions 114, and referring to Figs. 10 and 11 and Figs. 13 and 14, each of the recess structures 131 respectively comprises a light guide portion connection surface 132 in connection with the light guide portion 114 corresponding to the recess structure 131, an intermediate connection surface 133 in connection with the light guide portion connection surface 132, and an light passage connection surface 134 in connection with the intermediate connection surface 133, wherein a first cut-off portion 135 forming a first light shape cut-off line is provided at the connection between the intermediate connection surface 133 and the light passage connection surface 134. At this moment, the first light shape cut-off line formed by the first cut-off portion 135 can be designed according to specific application situations of the first optical element 1, e.g., it may be an auxiliary low-beam cut-off line, or an auxiliary high-beam cut-off line.

[0039] In the present invention, the first light emergent surface 12 is preferably a curved surface protruding forwards, and may be configured as a single and smooth curved light emergent surface, hereby improving the aesthetics of the appearance of the vehicle lamp. Correspondingly preferably, referring to Fig. 4, the first cut-off portion 135 is located on the median surface of the first light emergent surface 12, and the median surface is a horizontal plane passing through the vertex of a longitudinal transversal of the first light emergent surface 12, such that the first light shape cut-off line correspondingly formed by the first cut-off portion 135 is clearer and realizes a better light shape.

[0040] Further preferably, the first light emergent surface 12 is a curvature continuous curved surface, which improves the appearance and the light emerging effect of the first optical element 1.

[0041] The at least one first light incident structure according to the present invention may be specifically configured to have at least one low-beam first light incident structure 111, or have at least one high-beam first light incident structure 112, or have at least one low-beam first light incident structure 111 and at least one high-beam first light incident structure 112. There may be one, two, three or more low-beam first light incident structures 111 and/or high-beam first light incident structures 112, and the number may be configured according to actual application requirements of the vehicle lamp optical unit.

[0042] In order to simplify the structural design of the vehicle lamp optical unit, reduce positioning and installation errors between various vehicle lamp illumination units and between parts, and improve the installation accuracy, the projection plane shapes of the first light emergent surface 12 and the light incident structure reference plane 11 along the light emergent direction are respectively a strip-shape extending left and right; the first light incident structure is configured to be multiple low-beam first light incident structures 111 and multiple high-beam first light incident structures 112; the low-beam first light incident structures 111 and the high-beam first light incident structures 112 are arranged alternately; and each of the collimators 113 is located on the lower side of the light incident structure reference plane 11. At this moment, the first optical element 1 can be simultaneously used for forming partial light shape or complete light shape of the low beam or the high beam, and integrate multiple functions as a whole, thus making the structural design simple and compact. The alternate arrangement of the low-beam first light incident structures 111 and the high-beam first light incident structures 112 can meet the requirement that under the two modes, i.e., the low-beam mode and the high-beam mode, the first light emergent surface 12 has consistent lightening effect, and it is avoided that the first light emergent surface 12 is only partially lightened in a single low-beam mode, which affects the lightening effect of the vehicle lamp.

[0043] Based on the alternate arrangement of the low-beam first light incident structures 111 and the high-beam first light incident structures 112, the distance between the first cut-off portion 135 corresponding to the low-beam first light incident structure 111 and the upper surface of the first light passage 13 is greater than the distance between the first cut-off portion 135 corresponding to the high-beam first light incident structure 112 and the upper surface of the first light passage 13, that is to say, the first cut-off portion 135 corresponding to the high-beam first light incident structure 112 is higher than the first cut-off portion 135 corresponding to the low-beam first light incident structure 111, such that there is a segment difference the first cut-off portion 135 corresponding to the low-beam first light incident structure 111 and the first cut-off portion 135 corresponding to the high-beam first light incident structure 112. By providing the segment difference between the first cut-off portion 135 corresponding to the low-beam first light incident structure 111 and the first cut-off portion 135 corresponding to the high-beam first light incident structure 112, the high-beam light shape and the low-beam light shape have a certain superposition, that is to say, the cut-off line of the high-beam light shape is located below the cut-off line of the low-beam light shape, and accordingly, the adjoining effect between the low beam and the high beam is better.

[0044] Further specifically, the intermediate connection surface 133 corresponding to the low-beam first light incident structure 111 is configured to tilt upwards from back to front, and the side of the intermediate connection surface 133 facing the first light passage 13 is configured as a reflecting surface; and the intermediate connection surface 133 corresponding to the high-beam first light incident structure 112 is configured to tilt downwards from back to front, and the side of the intermediate connection surface 133 departing from the first light passage 13 is also configured as a reflecting surface. Referring to Fig. 11, light rays received by the low-beam first light incident structure 111 are subjected to a direction change by the light guide portion 114 and are emitted towards the first light passage 13, then most light rays are directly transmitted to the first light emergent surface 12 after passing through the first light passage 13 and being cut off by the corresponding first cut-off portion 135 thereof, while other minor light rays are directed to the corresponding intermediate connection surface 133 thereof and reflected by the intermediate connection surface 133 to the inside of the first light passage 13 for further transmission, so as to improve the luminous efficiency. Those two parts of light rays commonly form a light shape having an auxiliary low-beam cut-off line after emerging from the first light emergent surface 12. Referring to Fig. 12, the high-beam first light incident structure 112 takes the corresponding light guide portion connection surface 132 as a primary high-beam light emergent surface and takes the light passage connection surface 134 as a secondary high-beam light incident surface. Light rays received by the high-beam first light incident structure 112 emerge from the corresponding light guide portion connection surface 132 after direction change by the light guide portion 114. Most light rays directly enter the first light passage 13 through the corresponding light passage connection surface 134 after being cut off by the corresponding first cut-off portion 135, and are transmitted to the first light emergent surface 12, while other minor light rays are directed to the corresponding intermediate connection surface 133 thereof and reflected by the intermediate connection surface 133 to the corresponding light passage connection surface 134 and are further transmitted in the first light passage 13, so as to improve the luminous efficiency. Those two parts of light rays commonly form a light shape having an auxiliary high-beam cut-off line after emerging from the first light emergent surface 12.

[0045] Based on the above-mentioned first optical element according to the present invention, referring to Figs. 15 to 26, this vehicle lamp optical unit further comprises a second optical element 2; a notch for accommodating the second optical element 2 is formed on one side in the left and right direction of the first optical element 1; the rear end face and the front end face of the second optical element 2 along the light emergent direction are respectively a light incident surface 21 and a second light emergent surface 22; the light incident surface 21 is provided with at least one second light incident structure; and the second optical element 2 is configured to be capable of guiding light rays emerging from the second light emergent surface 22 to exit through the first light emergent surface 12. The first optical element 1 and the second optical element 2 share the first light emergent surface 12, which is more conducive to the combination of the light shapes of the two, such that the vehicle lamp optical unit forms a desired vehicle lamp light shape.

[0046] In order that the part of the first optical element 1 corresponding to the second optical element 2 and located in front thereof can form a single focus for forming a main low-beam cut-off line having an inflection point, the first optical element 1 is preferably provided with a secondary light incident surface 14, the secondary light incident surface 14 is located in the rear of the first light emergent surface 12 and faces the notch, and the secondary light incident surface 14 comprises at least one curved surface protruding backwards.

[0047] As a preferred embodiment of the second optical element 2, the light incident surface 21 is provided with multiple second light incident structures, and the multiple second light incident structures are configured 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 numbers of the low-beam second light incident structures 211 and the high-beam second light incident structures 212 may be configured according to requirements for the light shape formed by the second optical element 2; moreover, it is preferred that those two are molded as a whole, hereby improving the installation accuracy of the vehicle lamp optical unit.

[0048] Preferably, each of the low-beam second light incident structures 211 and each of the high-beam second light incident structures 212 are respectively a collimating structure. The collimating structure may be a collimating element, such as a collimating cup, so as to improve the light efficiency.

[0049] Specifically, referring to Figs. 20 and 21, the low-beam second light incident structure 211 is located above the high-beam second light incident structure 212; the second light emergent surface 22 comprises a low-beam light emergent surface 221 located in front of the low-beam second light incident structure 211 and a high-beam light emergent surface 222 located at the light emergent end of the high-beam second light incident structure 212; a second light passage 23 is provided between the light emergent end of the low-beam second light incident structure 211 and the low-beam light emergent surface 221; and a second cut-off portion 24 for forming a second light shape cut-off line is provided at the connection between the bottom surface of the second light passage 23 and the low-beam light emergent surface 221. The second light shape cut-off line may be a main low-beam cut-off line, or a main high-beam cut-off line. At this moment, referring to Fig. 22, light rays received by the low-beam second light incident structure 211 are emitted to the second light passage 23 to be transmitted to the low-beam light emergent surface 211 through the second light passage 23, and form a light shape having a main low-beam cut-off line via the second cut-off portion 24; and light rays received by the high-beam second light incident structure 212 directly emerge from the high-beam light emergent surface 222 and form a light shape having a main high-beam cut-off line via the second cut-off portion 24.

[0050] Further preferably, the lower surface of the second light passage 23 is configured as a reflecting surface. When partial light rays emitted by the low-beam second light incident structure 211 to the second light passage 23 are emitted to the lower surface of the second light passage 23, they are reflected by the reflecting surface to the inside of the second light passage 23 to be further transmitted; when partial light rays directed by the high-beam light emergent surface 222 are emitted to the lower surface of the second light passage 23, they are reflected by the reflecting surface to be further transmitted forwards, and the luminous efficiency can be improved by configuring the lower surface of the second light passage 23 as a reflecting surface. Typically, the low-beam light emergent surface 221 is configured as a curved surface protruding forwards, and specifically may be a curved surface protruding in up-down direction, or may also be a curved surface protruding in left-right direction, or may also be a curved surface protruding simultaneously in up-down direction and in left-right direction.
