DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The specific implementations of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementations described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0037] In the description of the present disclosure, it should be noted that, unless otherwise expressly specified and defined, the terms “connection” and “arrangement” should be understood in a broad sense, for example, connection may fixed connection, detachable connection, or integrated connection; connection may be direct connection or indirect connection through an intermediate medium, and connection may be the internal communication between two elements or the interaction relationship between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure may be understood according to specific situations.

[0038] First of all, it should be noted that, in the description of the following technical solutions of the present disclosure, the orientation terms are defined with the vehicle lamp module itself as the orientation reference, wherein, in the exit direction of the light path, the end where the lens 4 is located is the front, and the opposite end is the rear, the “upper” and “lower” refer to the upper and lower orientations of the lamp module. However, in the actual installation situation, due to the different arrangement positions of the vehicle lamp module in the vehicle, there are various possibilities of orientation arrangement, the orientation terms should be explained according to the actual installation state and in combination with the vehicle lamp module itself as the reference. The defining of the orientation of the vehicle lamp module does not constitute a limitation on the protection scope of the present disclosure.

[0039] Referring to FIG. 1 to FIG. 8, a vehicle lamp module according to a basic implementation of the present disclosure includes a lens 4, a shading plate 3 with a cut-off line structure 31 at one end, a low beam module and a high beam module, wherein light emitted by the low beam module is intercepted by the cut-off line structure 31 of the shading plate 3 and then emitted to the lens 4 to form a low beam type shown in FIG. 10. Light emitted by the high beam module is intercepted by the cut-off line structure 31 of the shading plate 3 and then emitted to the lens 4 to form a main high beam type located above a light and shade cut-off line and as shown in FIG. 11. The vehicle lamp module further includes an auxiliary high beam module, and light emitted by the auxiliary high beam module is intercepted by the cut-off line structure 31 of the shading plate 3 and then emitted to the lens 4 to form an auxiliary high beam type located below the light and shade cut-off line and as shown in FIG. 12.

[0040] An existing vehicle lamp module can also switch high beam and low beam, but the formed high beam type has obvious defects, the brightness of the high beam above a light and shade cut-off line is higher than the brightness of the high beam below the light and shade cut-off line, a part below the light and shade cut-off line forms a dark area where the high beam is distributed, and the high beam type generates a brightness gradient in the shape of the light and shade cut-off line, so that not only is the road surface lighting effect of high beam affected, but also certain potential safety hazards exist; the vehicle lamp module improves the prior art to a certain degree, part of high beam or low beam light is refracted or reflected to be guided to the position below a light and shade cut-off line so as to supplement light to the dark area of the high beam, however, it is difficult to adjust light by using the method, and the manufacturing difficulty of part of optical elements in the vehicle lamp module is increased.

[0041] The vehicle lamp module provided by the present disclosure is provided with the low beam module, the high beam module and the auxiliary high beam module, when the low beam module is activated, low beam light emitted by the low beam module is emitted to the shading plate 3, part of the low beam light is shielded by the shading plate 3, and part of the low beam light is emitted from the cut-off line structure 31 of the shading plate 3 and then refracted by the lens 4 to form a low beam type located below the light and shade cut-off line; when the high beam module is activated, high beam light emitted by the high beam module is reflected by the shading plate 3 and then refracted by the lens 4 to form a main high beam type located above the light and shade cut-off line, and the brightness of the main high beam is higher than that of the low beam; when the auxiliary high beam module is activated, light emitted by the auxiliary high beam module is emitted to the shading plate 3, part of the light is shielded by the shading plate 3, another part of the light is emitted from the cut-off line structure 31 of the shading plate 3 and then refracted by the lens 4 to form an auxiliary high beam type located below the light and shade cut-off line, and the auxiliary high beam type can supplement light to a dark area where the high beam is distributed and improve the brightness of high beam and the uniformity of the brightness of the high beam.

[0042] Referring to FIG. 10 to FIG. 14, the low beam type, the main high beam type and the auxiliary high beam type are all light distribution patterns with light and shade cut-off lines, the light distribution pattern of the auxiliary high beam is matched with the shape of a dark area in the light distribution pattern of the conventional high beam, and the auxiliary high beam type, the low beam type and the main high beam type can be combined into high beam with uniform brightness.

[0043] Specifically, the low beam module includes a low beam condensing element 11 and a light source, the high beam module includes a high beam condensing element 21 and a light source, and the auxiliary high beam module includes an auxiliary high beam condensing element 23 and a light source, wherein an LED light-emitting chip, an OLED light-emitting chip or a light-emitting chip based on a laser light source may be adopted as the light source; ellipsoidal or paraboloid reflection cups may be adopted as the low beam condensing element 11, the high beam condensing element 21 and the auxiliary high beam condensing element 23, or a condenser may also be adopted to play a role in condensing light.

[0044] Preferably, most of light emitted by the light source is converged to the cut-off line structure 31 of the shading plate 3 or near the cut-off line structure 31 by the low beam light condensing element 11, the high beam light condensing element 21 and the auxiliary high beam light condensing element 23, and the cut-off line structure 31 of the shading plate 3 is located on a focus of the lens 4 or near the focus. Due to such positioning, the light utilization rate can be improved, and a clearer light distribution pattern can be formed.

[0045] Furthermore, the low beam condensing element 11, the high beam condensing element 21 and the auxiliary high beam condensing element 23 are all set as reflection cups which are correspondingly referred to as a low beam reflection cup, a high beam reflection cup and an auxiliary reflection cup respectively, and the reflection cups may be ellipsoidal reflection cups or paraboloid reflection cups. Perifocuses of the low beam reflection cup, the high beam reflection cup and the auxiliary reflection cup are respectively provided with a low beam light source 12, a high beam light source 22 and an auxiliary high beam light source 24, apofocuses of the reflection cups fall on the cut-off line structure 31 of the shading plate 3, and it should be understood that the reflection cup has two focuses, the perifocus is a light incident point, and the apofocus is a light emergent point. Due to such arrangement of the relative positions of the low beam reflection cup, the high beam reflection cup, the auxiliary reflection cup, the shading plate 3 and the lens 4, the light utilization rate can be increased, and the formed light type is clearer.

[0046] As a specific structural form, referring to FIG. 1 to FIG. 3, the low beam reflection cup and the auxiliary reflection cup are assembled and connected or integrally formed to form a hyperboloid reflection cup, and the reflecting surface of the high beam reflection cup is opposite to the reflecting surface of the hyperboloid reflection cup. It needs to be noted that the reflecting surface of the high beam reflection cup being opposite to the reflecting surface of the hyperboloid reflection cup is not limited to the placement manner that the two reflecting surfaces are completely opposite, and as long as the light reflected by the hyperboloid reflection cup can be emitted to the upper surface of the shading plate 3, and the light reflected by the high beam reflection cup can be emitted to the lower surface of the shading plate 3, the reflecting surface of the hyperboloid reflection cup and the reflecting surface of the high beam reflection cup can be considered to be in an opposite arrangement state. According to the structure, the low beam reflection cup and the auxiliary reflection cup are integrated into the hyperboloid reflection cup, so that the number of optical elements of the vehicle lamp module is reduced; the hyperboloid reflection cup can be integrally formed, so that the production efficiency is improved, the production cost is reduced, and the light adjusting difficulty is reduced.

[0047] As another specific structural form, referring to FIG. 4 to FIG. 6, the reflecting surface of the low beam reflection cup is arranged opposite to the reflecting surface of the high beam reflection cup and the reflecting surface of the auxiliary reflection cup. Under such structural form, the radial size of the vehicle lamp module can be reduced.

[0049] Specifically, the high beam integrated condenser 5 is a transparent solid light conductor, and the high beam integrated condenser 5 is sequentially provided with or integrally formed with a light incident part 52, a light passing part and a light emergent part. Wherein the light incident part 52 is provided with a groove and a light incident surface protruding backwards, and the total high beam light source 51 is placed in the groove, due to the adoption of such a structure, light emitted by the total high beam light source 51 can be well collected, and the utilization rate of the light source can be improved; an upper total reflection surface 53 is formed on the upper surface of the light passing part, a lower total reflection surface 54 protruding outwards is formed on the lower surface of the light passing part, and light can be converged to the area of a cut-off line structure 57 of the high beam integrated condenser 5 after being reflected by the upper total reflection surface 53 and the lower total reflection surface 54; the light emergent part is provided with a first light emergent part 55 and a second light emergent part 56, light used for forming auxiliary high beam is emitted from the first light emergent part 55, and light used for forming main high beam is emitted from the second light emergent part 56; and the upper total reflection surface 53 and the second light emergent part 56 intersect to form the cut-off line structure 57. The relative position of the low beam reflection cup relative to the high beam integrated condenser 5 is adjusted, so that the apofocus of the low beam reflection cup is located on the cut-off line structure 57 of the high beam integrated condenser 5 or in the area nearby the cut-off line structure 57, and light converged by the low beam reflection cup is emitted to the cut-off line structure 57, intercepted by the cut-off line structure 57 and then refracted by the lens 4 to form a low beam type, and light emitted from the first light emergent part 55 and the second light emergent part 56 is intercepted by the cut-off line structure 57 and then refracted by the lens 4 to form an auxiliary high beam type and a main high beam type respectively.

[0050] Preferably, the cut-off line structure 57 of the high beam integrated condenser 5 is located at the focus of the lens 4 so as to form a clearer light type, and certainly, the cut-off line structure 57 may also be located near the focus of the lens 4.

[0051] Referring to FIG. 1 to FIG. 3, the vehicle lamp module according to a preferable implementation of the present disclosure includes three ellipsoidal reflection cups, namely a low beam reflection cup, a high beam reflection cup and an auxiliary high beam reflection cup; the perifocuses of the low beam reflection cup, the high beam reflection cup and the auxiliary high beam reflection cup are respectively provided with a low beam light source 12, a high beam light source 22 and an auxiliary high beam light source 24, the apofocuses of the low beam reflection cup, the high beam reflection cup and the auxiliary high beam reflection cup all fall into the area of the cut-off line structure 31 of the shading plate 3, and the focus of the lens 4 is located near the cut-off line structure 31 of the shading plate 3, wherein the low beam reflection cup and the auxiliary high beam cup may be integrally formed into a hyperboloid reflection cup. In the structure, when the low beam light source 12 is activated, low beam light emitted by the low beam light source 12 is emitted to the shading plate 3, a small part of the light is reflected by the upper reflecting surface of the shading plate 3, and most of the light is emitted from the cut-off line structure 31 of the shading plate 3 and then refracted by the lens 4 to form a low beam type located below a light and shade cut-off line; when the high beam light source 22 is activated, high beam light emitted by the high beam light source 22 is reflected to the lens 4 by the lower reflecting surface of the shading plate 3 and then refracted by the lens 4 to form a main high beam type located above the light and shade cut-off line, and the brightness of the main high beam is higher than that of the low beam; when the auxiliary high beam light source 24 is activated, light emitted by the auxiliary high beam light source 24 is emitted to the shading plate 3, part of the light is reflected by the upper reflecting surface of the shading plate 3, and another part of the light is emitted from the cut-off line structure 31 of the shading plate 3 and then refracted by the lens 4 to form an auxiliary high beam type located below the light and shade cut-off line. The auxiliary high beam below the light and shade cut-off line is superposed with the low beam and combined with the main high beam above the light and shade cut-off line to form the high beam, referring to FIG. 10 to FIG. 14, so that in the vehicle lamp module provided by the present disclosure, the auxiliary high beam is used for supplementing light to the dark area of the high beam below the light and shade cut-off line so as to provide the high beam with higher and more uniform brightness; and the brightness of the high beam formed by superposition can be more uniform by adjusting the brightness of the low beam light source 12, the high beam light source 22 or the auxiliary high beam light source 24, and the light adjusting method is simple.
