As shown in fig. 1, an embodiment of the present application provides a high mounted stop lamp, which includes: a lamp housing 10, a lens 20 and a light guide assembly 40; the lamp housing 10 may be a plastic housing, and the lamp housing 10 is not only used for mounting the lens 20 and the light guide assembly 40, but also used for being connected with a vehicle body to mount the high mounted stop lamp on the vehicle body.

The lens 20 is also called as light scattering glass, and is made of polycarbonate or polymethyl methacrylate and has a certain thickness. The lens 20 refracts the parallel light beam reflected by the light guide assembly 40. The lens 20 is coupled to the lamp housing 10 and forms an accommodating chamber for accommodating the light guide assembly 40, the control panel, and the like. The lens 20 has a transparent side facing the outside of the vehicle body so that light emitted from the stop lamp can be emitted through the lens 20 to form a lighting effect.

Referring to fig. 1, the edge of the lens 20 is provided with a welding rib 21, and the welding rib 21 may surround the edge of the lens 20. The lens 20 is welded to the lamp housing 10 by a welding rib 21. For example, the lens 20 and the lamp housing 10 can be welded together by a vibration friction welding process, which can ensure the sealing of the accommodating cavity between the lens 20 and the lamp housing 10.

It is understood that the welding method between the lens 20 and the lamp housing 10 is not limited to the vibration friction welding, but other welding methods such as hot plate welding, ultrasonic welding, laser welding, etc. can be used. Wherein, the hot plate welding is similar to the friction welding, and welding ribs are required to be arranged; and ultrasonic welding and laser welding can carry out plane welding, need not to set up the welding muscle. Therefore, the present embodiment can select a suitable welding method according to different welding requirements, and is not limited to the vibration friction welding method listed in the present embodiment.

As shown in fig. 2, in the embodiment of the present disclosure, the light guide assembly 40 is disposed in the accommodating cavity, and the light guide assembly 40 includes a light source 41 and a light guide 42; the light pipe 42 may be a circular pipe, and the length direction of the circular pipe may be the same as the length direction of the lamp housing. With such an arrangement, the light emitted from one side of the light pipe 42 can be emitted along the length direction of the brake lamp as much as possible, and the whole strip-shaped lamp strip can be presented.

The light guide assembly 40 may be provided with at least one light source 41. For example, one end of the light guide assembly 40 may be provided with a light source 41, and the light source 41 may be an LED light source. The LED light source and the light pipe 42 can be fixed in the lamp housing 10 by a bracket, and the LED light source and the light pipe 42 can be at the same height, so that the light emitted from the LED light source can be emitted into the light pipe 42 and spread along the length direction of the light pipe 42. When the light source 41 is turned on, the light emitted from the light source 41 may be incident into the light guide 42 and may be transmitted toward the other end of the light guide 42 along the longitudinal direction thereof.

Preferably, the light guide assembly 40 provided in the embodiment of the present application may include two light sources 41, and the two light sources 41 are respectively disposed at two ends of the light guide 42, that is, one light source may be disposed at each end of the light guide 42. For example, a first light source is disposed at a first end of the light pipe 42, a second light source is disposed at a second end of the light pipe, light emitted from the first light source propagates toward the second end of the light pipe 42, and light emitted from the second light source propagates toward the first end of the light pipe; that is, the light emitted from each light source 41 is transmitted toward the opposite side, so that the brightness of the light at each position in the light pipe 42 is uniform, and thus a lamp strip with uniform brightness can be formed.

One side of the light pipe 42 faces the lens 20, and the other side of the light pipe 42 is provided with light guide teeth 43, that is, the light guide teeth 43 are disposed on the side of the light pipe 42 away from the lens 20, which can be defined as the backlight side of the light pipe 42, so that the side opposite to the backlight side of the light pipe 42 can be defined as the light-emitting side of the light pipe 42, which is the side of the light pipe 42 close to the lens 20.

The light guide teeth 43 may be polygonal or arc-shaped protrusions formed on the inner wall of the light guide 42, which are generally vertically arranged in the light guide 42, and the light guide teeth 43 may totally reflect light. The light reflected by the light guide teeth 43 is emitted from the light exit side and can be directed to the lens 20. It can be understood that the inner wall of the light guide tube 42 is provided with a plurality of light guide teeth 43, and the plurality of light guide teeth 43 can be arranged on the inner wall of the light guide tube 42 at equal intervals; the light can be uniformly reflected to the lens 20.

The lens 20 is provided with optical lines for refracting the light reflected by the light guide teeth 43, and since the light guide teeth 43 are arranged in the light guide tube 42 in a vertical state, a plurality of light beams refracted by the light guide teeth 43 are bundled into a light beam, and the interval between adjacent light beams is changed, thereby forming a thick and sparse vertical stripe lamp band. Or, the optical lines are used for refracting the light reflected by the light guide teeth 43, and a plurality of light rays refracted by the light guide teeth 43 are more dispersed to change the interval between adjacent light rays, so that the densely arranged vertical stripe lamp bands are formed.

The optical texture may be provided on the outer surface or the inner surface of the lens 20, and the region where the optical texture is located may be opposite the light pipe 42. Preferably, the inner surface of the lens 20 is provided with a refraction surface 22, the refraction surface 22 is opposite to the light exit side of the light guide 42, and the optical texture is arranged in the refraction surface 22. So set up, compare and set up the optical line on the surface of lens 20, this application embodiment preferably sets up the optical line at the internal surface of lens 20, can promote the outward appearance of high-order stop lamp.

The light reflected by the light guide teeth 43 can pass through the optical grains in the refraction surface 22, and the optical grains can refract the light passing through the lens 20 and emit the light to the outside of the lamp housing 10, so as to form vertical stripe lamp bands with different intervals. It can be understood that the optical lines provided by the embodiment can change the display appearance of the lamp strip, and therefore the optical lines can be designed according to actual needs to meet the appearance requirements of different lamp strips.

Compared with the prior art that the light emitted by the light source 41 is emitted after being reflected by the light guide teeth 43, the light emitted by the high-mount stop lamp provided by the embodiment of the application is reflected by the light guide teeth 43 and refracted by the optical grains and then emitted out of the lamp housing 10; the specific propagation angle of the light reflected by the light guide teeth 43 can be changed, and the formed lamp strip has vertical stripes with different intervals, so that the lighting appearance of the vertical stripes with specific intervals in the existing lamp strip can be distinguished, the vertical stripes have different lighting appearances, and the purpose of highlighting is achieved.

As shown in fig. 3 to 5, to facilitate the description of the optical texture provided by the embodiment of the present application, a series of dimensions shown in fig. 3 to 5 may be first described. Dimension D is the distance between the light exit side of the light pipe 42 and the refractive surface 22 of the lens 20; dimension d is the span of the wave band in the optical pattern; the point P is an intersection point formed by longitudinally and transversely scribing lines at intervals of d, and L1 and L2 are arcs in which the lines pass through two adjacent intersection points P left and right/up and down, respectively.

As shown in fig. 3 and 5, the optical texture provided by the embodiment of the present application is disposed on the refractive surface 22 of the lens 20, and the refractive surface 22 belongs to a part of the inner surface of the lens 20; the refracting surface 22 may be a relatively flat surface. The distance D between the refracting surface 22 and the light exit side of the light pipe 42 may be 2 to 14 mm. When the distance D is less than 2mm, the brake lamp is likely to be fogged, thereby affecting the lighting effect. When the distance D is greater than 14mm, the refraction effect of the optical texture is weakened due to the excessively long transmission distance. For example, the distance D may be 3, 4, 5, 6,7, 8, 9, 10, 11mm, etc., and thus the lighting effect of the high-mount stop lamp can be improved.

Referring to fig. 5, the optical texture provided by the embodiment of the present application includes a plurality of wave patterns, and the plurality of wave patterns are arranged on the refraction surface 22 in a grid shape. For example, a straight line L₁And a straight line L₂A plurality of refraction surfaces 22 are arranged in a transverse and longitudinal staggered mode and represent the orthographic projection of each wave-shaped pattern. Each wave pattern comprises a plurality of continuous wave sections, and each wave section corresponds to the side of each square grid on the projection of the wave section. The span of each corrugated segment corresponds to the side length of each square in the orthographic projection.

The wave pattern provided by the embodiment of the present application may be a male type wave pattern 31 or a female type wave pattern 32, depending on the direction of the projection or depression of the above-described wave segments; this will be explained in detail below.

The convex wavy pattern 31 provided by the embodiment of the present application includes a plurality of continuous convex wavy segments, and the peak of each wavy segment is raised toward the light guide 42. In order to facilitate processing and beautify appearance, the span of each corrugated segment corresponding to the length d of the corrugated segment in the orthographic projection can be 0.7-1.5 mm; for example, the length d may be 1 mm. The bending radius R of each of the corrugated sections may be 2 to 5mm, which enables a good lighting display effect, for example, the bending radius R may be 3 mm.

As shown in fig. 6, when the convex wavy patterns 31 having the above-mentioned size are provided on the refractive surface 22 of the lens 20, after the high mounted stop lamp is turned on, the convex wavy patterns 31 have a focusing function, and can refract the light reflected by the light guide teeth 43, so that part of the light is converged together, resulting in more obvious light intensity, increased interval of darker areas, and overlapped light within a certain range, thereby forming a thick and sparse vertical stripe strip. Compared with the prior art that the inner surface of the lens 20 is not provided with optical lines, the vertical stripes of the lighted high-mount stop lamp become thicker in characteristic, and the interval between two adjacent vertical stripes is increased, so that the vertical stripes have obvious difference and more striking appearance.

Similarly, as shown in FIG. 4, the concave corrugation pattern 32 provided by the embodiment of the present application includes continuous concave corrugation segments, and the peak of each corrugation segment is concave towards the side far away from the light guide tube 42. The span of each corrugated segment may be 0.7 to 1.5mm corresponding to its length d in the orthographic projection, and the bending radius R of each corrugated segment may be 2 to 5 mm; also, the length d is preferably 1mm, and the bending radius R may be 3 mm.

As shown in fig. 7, when the refraction surface 22 of the lens 20 has the concave wavy patterns 32 with the above size, after the high-mount stop lamp is turned on, the concave wavy patterns 32 have a diverging function, and can refract the light reflected by the light guide teeth 43, so that the light arrangement is more uniform, the darker area of the light becomes smaller, and the bright line area becomes denser, thereby forming the densely arranged vertical stripe lamp strip; the vertical stripe structure can be further refined, the uniformity of the lighting effect is enhanced, and a unique lighting appearance pattern is formed.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the utility model, and the technical scheme after the changes or substitutions can fall into the protection scope of the utility model.
