Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present application.

[0022] The present application comprises a tail lamp body 1 and a screen support 2, as shown in Figure 1 , 2 The tail lamp body 1 comprises a bottom shell support 11, a decorative frame 12 and a face shield 13. The bottom shell support 11 is installed at the tail of the car. The screen support 2 is installed on the bottom shell support 11. The decorative frame 12 is installed on the bottom shell support 11 and is arranged along the edge of the screen support 2. The face shield 13 is installed on the decorative frame 12 and is located in front of the pixel module 3. The pixel module 3 is used for displaying patterns. The face shield 13 is used for converging and diverging light. The decorative frame 12 is also provided with a bright strip. The decorative frame 12 and the bright strip play a decorative role.

[0023] The screen support 2 is arranged in a curved manner along the length direction, and a plurality of pixel modules 3 are arranged in sequence along the length direction of the screen support 2. Each pixel module 3 comprises a light-transmitting screen plate 31 and a pixel screen 32. The light source generating side of the pixel screen 32 is attached to the back of the light-transmitting screen plate 31, so that the pixel screen 32 is fixed on the light-transmitting screen plate 31. In the embodiment, the pixel screen 32 comprises a circuit board fixed on the pixel screen 32, and a plurality of Mini-LED lamp beads are packaged on the circuit board. The Mini-LED lamp beads serve as the light source generating component of the pixel screen 32, and are arranged in a matrix on the pixel screen 32. Finally, the image generated by the pixel screen 32 is projected to the light-transmitting screen plate 31. Since the Mini-LED lamp bead is a sub-millimeter light-emitting diode, it is not shown in the drawings.

[0024] In the embodiment, the light-transmitting screen plate 31 is in the form of a thin plate with a small square or rectangular shape. A plurality of light-transmitting screen plates 31 are arranged in sequence and closely distributed to form a screen whole in a splicing manner. Since the light-transmitting screen plate 31 is in a small block structure, a plurality of light-transmitting screen plates 31 can form a curved screen effect after being distributed along the curved screen support 2, thereby greatly improving the design space and flexibility of the vehicle lamp and being applicable to the design of automobile tail lamps with different shapes.

[0025] As shown in Figure 4 , the back of the light-transmitting screen plate 31 is provided with a mounting column 4. One end of the mounting column 4 is connected to the light-transmitting screen plate 31, and the other end is detachably connected to the screen support 2. Thus, the pixel modules 3 on the screen support 2 can be individually assembled and disassembled, facilitating later maintenance. Fasteners such as screws are arranged on the mounting column 4, so that the light-transmitting screen plate 31 can be fixed on the screen support 2. The connection structure is simple and easy to operate.

[0026] Further, the light-transmitting screen plate 31 can be in the form of a thin plate with a polygonal shape such as a square, a triangle, a trapezoid, a parallelogram, and a hexagon. Adjacent sides of adjacent two light-transmitting screen plates 31 can be in contact or separated. In the embodiment, the light-transmitting screen plate 31 is in the form of a square, and the sides of the light-transmitting screen plate 31 are all horizontal surfaces perpendicular to the front or back. Adjacent sides of adjacent two light-transmitting screen plates 31 are in contact. Since the screen whole is in a curved effect, when adjacent light-transmitting screen plates 31 are in contact, the adjacent sides are not completely attached but form an included angle a with each other, as shown in Figure 5 , the front end 31a of the adjacent sides is in contact, while the back end 31b is separated, so that the included angle a is formed between the adjacent sides, 5°≤a≤10°. Of course, the adjacent sides of adjacent two light-transmitting screen plates 31 can also be separated, that is, the adjacent sides of adjacent two light-transmitting screen plates 31 are not in contact, and a small gap is left between the adjacent sides. In this way, a plurality of light-transmitting screen plates 31 can be spliced to form a curved screen along the curved screen support 2.

[0027] The curved screen can be inwardly curved or outwardly curved. In the embodiment, the curved screen is outwardly curved, depending on the bending direction of the screen support 2.

The heat dissipation hole 28 is arranged at the bottom of the groove 22. The mounting plate 21 is provided with mounting holes 23 on both sides of the groove 22. One end of the mounting column 4 is connected with the light-transmitting screen plate 31, and the other end is connected with the mounting hole 23 through a fastener. The depth of the groove 22 plus the length of the mounting column 4 makes the distance between the pixel module 3 and the heat dissipation hole 28 longer, which is beneficial to heat dissipation.

[0030] Further, the lower end of the mounting plate 21 is provided with a front support plate 24, which extends forward and is integrally arranged with the mounting plate 21. The front support plate 24 is located below the light-transmitting screen plate 31 and abuts against the lower end of the light-transmitting screen plate 31, so that the front support plate 24 supports the light-transmitting screen plate 31.

[0031] Further, the back of the mounting plate 21 is provided with a rear support plate 25 extending rearward and integrally provided with the mounting plate 21, the control assembly 5 can be mounted on the rear support plate 25, or can also be mounted on the back of the mounting plate 21 and supported by the rear support plate 25, so as to avoid mounting the control assembly 5 directly on the back of the mounting plate 21 to increase the load of the mounting plate 21, and a reinforcing rib 26 is arranged between the bottom of the rear support plate 25 and the back bottom of the screen support 2 to strengthen the strength of the rear support plate 25, thereby facilitating mounting or supporting the control assembly 5, in the embodiment, the control assembly 5 includes a driving plate 51 and a PCB plate 52, both of which are electrically connected to the circuit board of the pixel screen 32 through wires, the driving plate 51 is mounted vertically in a transverse manner on the back of the mounting plate 21, and a distance is left between the driving plate 51 and the mounting plate 21, the bottom of the driving plate 51 abuts against the rear support plate 25, so that the rear support plate 25 supports the driving plate 51, and when the number of driving plates is multiple, the driving plates are sequentially and spacedly arranged along the length direction of the screen support 2, the PCB plate 52 is fixed horizontally on the rear support plate 25, and the control assembly 5 further includes other accessories, and the connection mode and working principle of the accessories of the control assembly 5 are both conventional technologies, and details are not described herein.

[0032] Further, as shown in Figure 3 the screen support 2 is of a metal sheet structure, that is, the mounting plate 21 is of a sheet structure, the upper and lower ends of the mounting plate 21 are bent twice to form the upper and lower sides of the mounting plate 21, the lower side of the mounting plate 21 is bent forward again to form the front support plate 24, and the rear support plate 25 extends from the back of the mounting plate 21, so as to form the integral screen support 2, the upper side of the mounting plate 21 and the front support plate 24 are both provided with connecting holes 27, the screen support 2 is connected to the bottom shell support 11 through fasteners matched with the connecting holes 27, and the front support plate 24 of the screen support 2 is just attached to and abuts against the surface of the bottom shell support 11, so as to ensure the overall strength and stability of the screen support 2 and prevent the screen support 2 from being broken or loosened during the bumping of the automobile. In order to prevent short circuit, the screen support 2 and the control assembly 5 are well insulated.

[0033] The utility model is not limited to the above best embodiment, and anyone can derive other various forms of products under the inspiration of the utility model, but no matter any change in shape or structure, any technical scheme with the same or similar technology of the application falls within the protection scope of the utility model.
