The vehicle window generally comprises a front windshield (front windshield), a rear windshield (rear windshield), a side window and a skylight, and is mainly used for meeting the use requirements of lighting, ventilation, passenger vision and the like in the vehicle. The window light-transmitting member refers to a light-transmitting part mainly meeting the visual field requirement of passengers, such as front windshield glass or side window glass, and a light-transmitting part mainly meeting the ventilation requirement, such as skylight glass. And because door window printing opacity spare only possesses simple printing opacity function, the function is comparatively single, leads to the product homogeneity too serious, does not possess the novel function that attracts the customer for the vehicle can not form better market competition.
In view of the above, the present invention provides a vehicle window light-transmitting member light-emitting assembly, which is disposed on a vehicle body, and refer to fig. 1 and 2, wherein fig. 1 is a schematic structural diagram of an embodiment of the vehicle window light-transmitting member light-emitting assembly, and an arrow in the diagram indicates a propagation direction of a light beam; fig. 2 is a cross-sectional view of the light emitting assembly of the window light-transmitting member of fig. 1, the cross-sectional view being vertically extended, and the arrows and the dotted lines in the light-transmitting member collectively indicate the traveling direction of the light beam. In one embodiment of the present invention, the vehicle window light emitting assembly includes:
the light-transmitting piece 10 is provided with a first side surface 11 and a second side surface 12 which are oppositely arranged, and a first end surface 13 connecting the first side surface 11 and the second side surface 12, the light-transmitting piece 10 is provided with an incidence part 20, and the incidence part 20 is provided with an incidence surface 21; and
the light source 30 is disposed toward the incident surface 21 so that the emitted light beam can enter the incident portion 20 through the incident surface 21 and exit the light-transmitting member 10 through the first end surface 13.
In the technical scheme of the invention, at least one part of the light beam is emitted out through the first end surface 13 by utilizing the light source 30 which emits the light beam towards the light-transmitting piece 10, so that a light-emitting effect is formed at the first end surface 13 and can be noticed by personnel inside and outside the vehicle, the additional functions of the light-transmitting piece 10 are enriched, the use interestingness of the light-transmitting piece 10 is improved, the effect of an atmosphere lamp can be achieved, the driving pleasure of passengers is improved, the vehicle provided with the light-emitting structure of the light-transmitting piece of the vehicle is further enabled to avoid the product homogenization problem with other vehicle types in the market, and the market competitiveness is further improved. Of course, the light beam can be partially refracted out through the first side surface 11 and/or the second side surface 12, so that a person inside or outside the vehicle can perceive the light emitting area on the first side surface 11 and/or the second side surface 12 on the light beam propagation path, thereby enriching the light emitting effect of the light-transmitting member 10, and not only being limited to the first end surface 13 to have the light emitting effect.
Referring to fig. 2, in the present embodiment, the light beam is optionally emitted to the incident surface 21 in a direction parallel to the normal of the incident surface 21. It should be noted that parallel refers to a parallel and near-parallel relationship. Therefore, the light beam can carry more light energy into the incident part 20, so that the requirement on the luminous power of the light source 30 is reduced when the first end face 13 meets the technical requirement of the same luminous intensity, the light source 30 can be selected to be a model with smaller power, and the manufacturing cost and the using cost of the light source 30 are reduced. Specifically, the greater the light energy when the light beam enters the incident portion 20, the greater the light energy reaching the first end surface 13, and the brighter the light emission of the first end surface 13, the more easily perceived the light emission effect, but the less bright the light emission is, the discomfort of perception is not caused, and the driving safety problem of the host vehicle or the surrounding vehicle is caused. Therefore, under the condition of meeting a certain design requirement of luminous intensity, if the ratio of the light energy of the light beam entering the incidence part 20 to the total light energy is larger, the total light energy of the light beam emitted by the light source 30 can be smaller, thereby reducing the requirement on the luminous power of the light source 30. It can be understood that, when the light passes through the interface between the two media, the smaller the incident angle of the light, the smaller the light energy of the reflected light will be, and thus the greater the light energy entering the incident portion 20; and when the light is vertically incident to the interface, the energy loss caused by reflected light is avoided, and the propagation direction is not changed.
Referring to fig. 2, in this embodiment, optionally, the first side surface 11 and the second side surface 12 are arranged in parallel, and an included angle between a normal of the incident surface 21 and a normal of the second side surface 12 is larger than a total reflection critical angle of the light-transmitting member 10. Therefore, the light beams can be totally reflected on the first side surface 11 and the second side surface 12, that is, totally reflected in the light-transmitting member 10, so that most of the light beams can be emitted out of the light-transmitting member 10 through the first end surface 13, the light-emitting effect of the first end surface 13 is further improved, and the requirement on the light-emitting power of the light source 30 can be reduced when the first end surface 13 meets the technical requirement on the same light-emitting intensity.
Referring to fig. 1 and 2, in the present embodiment, the incident portion 20 is optionally a light guide connected to the light-transmitting member 10, the light guide further has a bonding surface 22 bonded to the first side surface 11, and the light beam sequentially passes through the incident surface 21, the bonding surface 22, and the first side surface 11 and enters the light-transmitting member 10. The light guide member is separated from the light transmission member 10, and is mainly used for guiding the light beam obliquely emitted to the first side surface 11 into the light transmission member 10, entering the light transmission member 10 in a maximum light energy state, and meeting the incident angle condition of forming total reflection in the light transmission member 10. Because the light guide part is directly connected to the first side surface 11, the light beam can enter the light transmission part 10 and the medium conditions required by total reflection and propagation can be achieved, the technical scheme can be directly applied to the existing vehicle light transmission part 10, and therefore the production cost of the vehicle light transmission part light-emitting structure can be reduced. However, the design is not limited thereto, referring to fig. 3, fig. 3 is a schematic structural view of another embodiment of the light emitting assembly of the vehicle window light-transmitting member of the present invention; in another embodiment, the incident portion may be a sinking groove 12 'on the first side surface 11', and the incident surface 13 'is disposed on a groove wall of the sinking groove 12'. Referring to fig. 4, fig. 4 is a schematic structural view of a light-emitting assembly of a vehicle window light-transmitting member according to still another embodiment of the present invention; in another embodiment, the light-transmitting member 10 "may further have a second end surface 12" disposed opposite to the first end surface 11 ", and the incident surface 13" is disposed on the second end surface 12 "; the incident surface may be intersected with the second end surface as shown in fig. 4, or may be overlapped with the second end surface, that is, the light beam passes through the incident surface perpendicularly and then is directed towards the first end surface without being refracted or reflected on the first side surface or the second side surface.
In this embodiment, optionally, the light guide member is fixedly disposed on the first side surface 11. So, can guarantee the inseparable laminating relation between binding face 22 and the first side 11 to still possess more light energy when being favorable to the light beam to get into first side 11 through binding face 22, avoid producing the clearance between binding face 22 and the first side 11, lead to the light beam to take place unnecessary reflection in the clearance, and make the problem that light energy reduces when getting into printing opacity piece 10. However, the design is not limited thereto, and in other embodiments, the light guide member may be fixedly disposed relative to the vehicle body, and the attachment surface may slide relative to the first side surface; this scheme is applicable to the condition that the printing opacity piece can remove vehicle body relatively, for example when applying to side window printing opacity piece, keep under the unchangeable prerequisite of incident surface and light source relative position relation, when side window printing opacity piece goes up and down, because the binding face still keeps the inseparable laminating relation with first side in the slip in-process, thereby make the light beam can vertical jet incident face and enter into leaded light spare, and in the direct entering printing opacity piece of binding face, and then make side window printing opacity piece at the lift in-process, first terminal surface can continuously keep luminous effect.
In this embodiment, optionally, the refractive index of the light guide member is the same as that of the light transmissive member 10. Thus, the light beam is not reflected or refracted at the joint surface 22, but directly enters the light-transmitting member 10 along the original direction (the direction of propagation in the light guide member), thereby avoiding the loss of light energy caused by the reflection of the light beam.
In this embodiment, optionally, the light guide member is made of glass. The glass material has good light transmittance, so that most of light energy can be still kept after the light beam passes through the light guide part. However, the design is not limited thereto, and in other embodiments, the light guide member may be a PC (Polycarbonate) material, a PMMA (polymethyl methacrylate) material, or a PU (Polyurethane) material with a light transmittance of more than 90%.
In this embodiment, in order to make the refractive indexes of the light guide member and the light transmission member 10 more easily consistent, optionally, the light transmission member 10 is made of glass, and the light guide member and the light transmission member supplied in the same batch can be prepared by using the same batch of products produced in the same glass manufacturing plant. However, the design is not limited thereto, and in other embodiments, the light-transmitting member may be made of a transparent PC material. Wherein the refractive index of the common glass is 1.1 to 2.1, preferably, the refractive index is 1.3 to 1.7; the critical angle of total reflection of the glass is 25 to 65 °, preferably 30 to 42 °.
In this embodiment, in order to simplify the installation process between the light guide member and the first side surface 11 and further reduce the production cost of the vehicle light-transmitting member light-emitting structure, optionally, the light guide member is fixedly bonded to the first side surface 11. However, the design is not limited thereto, and in other embodiments, the light guide member may be fixed to the first side surface 11 by a screw locking structure, a rivet structure, or a welding structure.
In this embodiment, the attaching surface 22 of the light guide member includes a first surface section and a second surface section annularly disposed on the first surface section, the first surface section is attached to the first side surface 11, a gap is formed between the second surface section and the first side surface 11, the gap is used for filling an adhesive, and the light beam is emitted into the light-transmitting member 10 through the first surface section and the first side surface 11. Thus, the adhesive does not affect the close fit between the first surface section and the first side surface 11, and the light beam can directly reach the first side surface 11 after passing through the first surface section.
In this embodiment, the light source 30 optionally includes a plurality of point light sources 30 spaced apart along the extending direction of the first end surface 13. In this way, the light emission intensity distribution of the first end surface 13 in the extending direction can be more uniform, and the problem that the area on the first end surface 13 close to the light source 30 is bright and the area far from the light source 30 is dark can be avoided, thereby improving the light emission effect of the first end surface 13. However, the design is not limited to this, in other embodiments, the light source may include a point light source, and a prism disposed in front of the point light source, the prism may enable light emitted by the point light source to emit a fan-shaped light beam to the incident surface, and the plane of the fan-shaped light beam is disposed in parallel with the extending direction of the incident portion; it should be noted that the front of the point light source refers to the side of the point light source emitting the light beam; the prism can be a Powell prism or a cylindrical prism, so that the light-emitting effect similar to that of a word line infrared laser is realized.
In the present embodiment, the light source 30 further includes a first controller electrically connected to each of the plurality of point light sources 30, and the first controller is capable of controlling at least two of the point light sources 30 to independently emit light. The first controller is utilized to orderly control the plurality of point light sources 30 to emit light according to a certain sequence, or gradually increase or weaken the light emitting intensity according to a certain rule, or control the plurality of point light sources 30 to emit light with different colors, so that the first end surface 13 generates the light effect of a breathing lamp, a rhythm atmosphere lamp or a running water horse race lamp, the use function of the vehicle light-transmitting part light-emitting structure is further enriched, the use interest is improved, and the market competitiveness of a vehicle provided with the vehicle light-transmitting part light-emitting structure is further improved.
