TECHNICAL FIELD
[0001] The present application relates to the field of vehicle lamps, in particular to an integrated tail lamp. BACKGROUND
[0002] The existing electric vehicle tail lamp structure is a split tail lamp and a combined tail lamp. The turn signal lamp and the rear tail lamp of the split tail lamp are separated, and the turn signal lamp and the rear tail lamp of the combined tail lamp are integrated. According to the national requirements, the rear tail lamp is red, and the turn signal lamp is amber. Most of the existing market is the combined tail lamp, which needs three thick walls to perform different functions, and there is no connection between the thick walls. In order to prevent light interference between the thick walls, a baffle is added between the thick walls to prevent light interference when the lamp structure is assembled. Another implementation is to diffuse through a diffuser cover, especially for miniaturized integrated tail lamps. However, whether it is an integrated thick wall or an integrated tail lamp through a whole diffuser cover, there will be a dark area or light leakage problem. CONTENT OF THE UTILITY MODEL

The brake lamp bead and the turn signal lamp bead are arranged on the circuit board. The lampshade and the tail shell are installed together to form a closed inner cavity. The inner cavity comprises a left turn area, a right turn area and a middle area. The turn signal lamp bead comprises a left turn lamp bead and a right turn lamp bead. The left turn lamp bead is arranged in the left turn area, and the right turn lamp bead is arranged in the right turn area. The brake lamp bead comprises a left brake lamp bead, a right brake lamp bead and a middle brake lamp bead. The left brake lamp bead is arranged in the left turn area, the right brake lamp bead is arranged in the right turn area, and the middle brake lamp bead is arranged in the middle area. The baffle comprises a left baffle and a right baffle. The left baffle and the right baffle are designed symmetrically. The left baffle is located on the right side of at least one left turn lamp bead, and at least one left brake lamp bead is located on the left side of the left turn lamp bead. The range of the light emitted by the left brake lamp bead to the right side which is blocked by the left baffle is smaller than the range of the light emitted by the left turn lamp bead to the right side which is blocked by the left baffle. Therefore, when the left turn lamp bead is on, the left baffle limits the light of the left turn lamp bead within a certain range to prevent light leakage. When the left brake lamp bead is on, the light of the left brake lamp bead and the middle brake lamp bead intersects with each other to prevent the formation of a dark area.
[0005] In an implementation, the left baffle comprises a first baffle and / or a second baffle. The first baffle is higher than the second baffle.
[0006] In an implementation, the end of the second baffle is bent to the left.
[0007] In an implementation, the cross section of the first baffle is T-shaped, i.e. the end is bent to the left and right sides, which can block the adjacent lamp beads on the left and right sides to avoid light leakage of the adjacent lamp beads.
[0008] In an embodiment, the lampshade is in a semi-cylindrical structure, and the ends of the first baffle are in a circular arc structure and are equidistantly arranged on the inner wall of the lampshade.
[0009] In an embodiment, a plurality of second baffles are arranged in the left-turn area.
[0010] In an embodiment, the ends of the first baffle are in an arch structure when viewed from the front, the ends are respectively curved to the left and right when viewed from the side, and the two sides are also in an arch structure when viewed from the top, so that the intersection line of the bright areas formed by the shielding of the first baffle on the semi-cylindrical lampshade is in the same vertical plane.
[0011] In an embodiment, the left baffle and the right baffle are arranged on the same mounting plate, and the mounting plate is mounted to the tail shell.
[0012] In an embodiment, the mounting plate is provided with a plurality of lamp holes, and at least part of the brake lamp beads and the turn signal lamp beads are arranged in the lamp holes.
[0013] In an embodiment, a diffuser cover is arranged in the lampshade, and the diffuser cover is fixed to the mounting plate by ultrasonic welding.
[0014] Compared with the prior art, the integrated tail lamp has the following beneficial effects: the left baffle and the right baffle are used to isolate the light of the turn signal lamp beads, the illumination range of the turn signal lamp beads can be limited, the technical effect of preventing light leakage is achieved, the position difference between the turn signal lamp beads and the brake lamp beads is used, the brake lamp beads have a larger light illumination range relative to the turn signal lamp beads, the light of the brake lamp beads at different positions can be staggered together to form an overall light structure, the appearance of a dark area is avoided, the tail lamp has an integrated structure when braking, is more beautiful, and has a clear position contour when turning, so that the turning is clearer.

[0028] In order to make the objectives, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, left and right as well as front and back are relative positions, and any position adjustment and replacement belongs to the conventional technical means, and all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the present application.
[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the integrated taillight includes a lampshade 4, a brake lamp bead 1, a turn lamp bead 2, a circuit board 5, a tail shell 6 and a baffle 3. The brake lamp bead 1 and the turn lamp bead 2 are arranged on the circuit board 5. The lampshade 4 and the tail shell 6 are installed together to form a closed inner cavity 10. The lampshade 4 and the tail shell 6 can be ultrasonically welded together. The inner cavity 10 includes a left-turn area 7, a right-turn area 9 and a middle area 8. The middle area 8 is located between the left-turn area 7 and the right-turn area 9. The turn lamp bead 2 includes a left-turn lamp bead 21 and a right-turn lamp bead 22. The left-turn lamp bead 21 is arranged in the left-turn area 7, and the right-turn lamp bead 22 is arranged in the right-turn area 9. The brake lamp bead 1 includes a left brake lamp bead 11, a right brake lamp bead 12 and a middle brake lamp bead 13. The left brake lamp bead 11 is set in the left turn area 7, the right brake lamp bead 12 is set in the right turn area 9, and the middle brake lamp bead 13 is set in the middle area 8. The baffle 3 includes a left baffle 31 and a right baffle 34. The left baffle 31 and the right baffle 34 adopt a symmetrical design. The turn lamp bead 2 and the brake lamp bead 1 can also adopt a symmetrical design, that is, symmetrically distributed on the left and right sides. The left turn lamp bead 21 is provided with a left baffle 31. The left baffle 31 is located on the right side of the left turn lamp bead 21, and the left brake lamp bead 11 is located on the left side of the left turn lamp bead 21. Figure 7 The dotted line indicates the direction of the main light from each lamp bead. The range of light emitted to the right by the left brake lamp bead 11 and blocked by the left baffle 31 is smaller than the range of light emitted to the right by the left turn lamp bead 21 and blocked by the left baffle 31. When the left turn lamp bead 21 is on, the left baffle 31 limits the light from the left turn lamp bead 21 to a certain range to prevent light from crossing with the middle brake lamp bead 13. When the left brake lamp bead 11 is on, the light from the left brake lamp bead 11 and the middle brake lamp bead 13 intersect to prevent the formation of dark areas. The brightest illumination range of the brake lamp bead 1 and the turn lamp bead 2 is ±30°, that is, the luminous angle is 60°. Figure 7 In the figure, the dashed line representing the luminous angle of the left brake lamp 11 is drawn at a 40° angle. Therefore, at a luminous angle of 60°, the light from the left brake lamp 11 can intersect with the light from the center brake lamp 13. Beyond this range, the visual effect is largely unaffected at lower brightness levels, preventing light from colliding between the left turn lamp 21 and the more distant center brake lamp 13. The integrated taillight features an intelligent control circuit that disables the left brake lamp 11 when the left turn lamp 21 is illuminated, preventing light from colliding with the center brake lamp 13. When the left turn lamp 21 is off, if the brake pedal is pressed, all brake lamps 1 illuminate, allowing the light from the left brake lamp 11 to intersect with the light from the center brake lamp 13 to avoid dark areas.
[0030] Example 1:
[0031] like Figure 3 As shown, the left baffle 31 includes a first baffle 32 and a second baffle 33 , and the first baffle 32 is higher than the second baffle 33 .
[0032] like Figure 1 、Figure 2 、 Figure 3 and Figure 4 The second baffle 33 is bent to the left at the end.
[0033] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The lampshade 4 is in a semi-cylindrical structure, and the end of the first baffle 32 is in a circular arc structure and is arranged equidistantly from the inner wall of the lampshade 4.
[0034] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The left baffle 31 and the right baffle 34 are arranged on the same mounting plate 35, and the mounting plate 35 is mounted to the tail shell 6.
[0035] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The mounting plate 35 is provided with a plurality of lamp holes 36, and at least part of the brake lamp beads 1 and the turn signal lamp beads 2 are arranged in the lamp holes 36. The mounting plate 35 is integrally injection molded with the left baffle 31 and the right baffle 34.
[0036] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The lampshade 4 is provided with a diffuser cover 40, and the diffuser cover 40 is fixed on the mounting plate 35 by ultrasonic welding.
[0037] Example 2:
[0038] As shown in Figure 5 The first baffle 32 is in a T-shaped cross section, that is, the end is bent to the left and right sides, which can shield the left turn lamp beads 21 and the middle brake lamp beads 13 adjacent to the left and right sides, and avoid light leakage between adjacent lamp beads. The rest is referred to Example 1.
[0039] Example 3:
[0040] As shown in Figure 6 and Figure 7 The second baffle 33 is arranged in the left turn area 7, and more than two are arranged in the same way in sequence. The right turn area 9 is also provided with the same number of baffles 3.
[0041] As shown in Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the first baffle 32 is arched at the end in the front view, curved to the left and right at the end in the side view, and arched at the two sides in the top view, so that the intersection line 41 of the bright area formed by the shielding of the first baffle 32 on the semi-cylindrical lampshade 4 is in the same vertical plane, and the shape of the final intersection line 41 is determined by the projection of the first baffle 32 in the vertical light irradiation direction, so the shape change at other positions does not affect the final shape of the intersection line 41, and the intersection line 41 in the same plane is more beautiful and has an independent turn signal visual effect. The right turn area 9 can be symmetrically provided with a corresponding baffle 3. The arrow direction in the figure is the light irradiation direction, and the illumination range of the brake lamp bead 1 is large, so there is no obvious dark area during braking, and the illumination range of the turn signal lamp bead 2 is small, so it emits light in a limited area under the action of the baffle 3 and does not interfere with the central area.
[0042] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
