Detailed Description of the Embodiments
[0034] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
[0035] Refer to Figure 1, showing a headlight structure provided by an embodiment of the present invention, including:
[0036] A light-emitting diode module 1, including a plurality of light-emitting diode units;
[0037] In this embodiment, the light-emitting diode module 1, namely the LED module, and the plurality of light-emitting diode units provided thereon, namely a plurality of LED particles, are the light sources of the headlight structure. Controlling the lighting and extinguishing of the plurality of LED particles can form different display patterns and can also display dynamic effects.
[0038] In some embodiments of the present invention, the light-emitting diode module 1 further includes:
[0039] A fixing bracket 102;
[0040] A flexible printed circuit board 103, mounted and fixed on one side of the fixing bracket 102, and the flexible printed circuit board 103 is provided with the plurality of light-emitting diode units;
[0041] A driving board 101, mounted and fixed on the other side of the fixing bracket 102, and the driving board 101 is electrically connected to the flexible printed circuit board 103.
[0042] In this embodiment, as Figure 2 shown, the driving board 101, the fixing bracket 102, and the flexible printed circuit board 103 constitute the light-emitting diode module 1. The flexible printed circuit board 103, namely the FPC (Flexible Printed Circuit), is provided with a plurality of light-emitting diode units (i.e., LED particles) and is the light source of the headlight; the driving board 101 integrates control software and related circuit components for controlling the display of the LED particles, such as controlling the pattern formed by the LED particles, the brightness of the LED particles, the color of the light of the LED particles, etc.; due to the characteristics of its flexible material, the flexible printed circuit board 103 can be directly connected to the driving board 101 to achieve electrical connection, as Figure 3 shown. The fixing bracket 102 is used to mount and fix the driving board 101 and the flexible printed circuit board 103. In practical applications, the shape of the fixing bracket 102 can match the shape of the decorative ring 4.
[0043] In some embodiments of the present invention, the driving board 101 includes:
[0044] A microcontroller unit;
[0045] A flash memory unit, the flash memory unit is electrically connected to the microcontroller unit and the voltage regulator respectively, and the voltage regulator is electrically connected to the plurality of light-emitting diode units.
[0046] In this embodiment, if Figure 4 As shown, the driving board 101 includes a microcontroller unit (i.e. Figure 4 MCU, Microcontroller Unit), flash memory unit (i.e. Figure 4 Flash in), voltage regulator (i.e. Figure 4 The microcontroller unit is used to control each light-emitting diode unit, and the flash memory unit is used to store and extract the designed patterns, animations and software. In practical applications, the patterns, animations and software can also be upgraded through OTA (Over-The-Air); the voltage regulator is used to maintain the stability and accuracy of the output voltage to avoid flickering and uneven brightness of the light-emitting diode unit.
[0047] In actual applications, when the microcontroller unit receives a signal instruction from the LCU (Lighting Control Unit), it reads the specified pattern or animation information and software stored in the flash memory unit according to the signal instruction, and further passes the pattern or animation information to the voltage regulator, and controls the patterns or animations displayed by multiple light-emitting diode units by running the software corresponding to the pattern or animation information.
[0048] In practical applications, such as Figure 4 As shown, the circuit structure in the driving board 101 may also include a protection circuit (ie Figure 4 protection), protection circuit and filter (i.e. Figure 4 Filter) in the circuit board, and the filter is electrically connected to the single board computer (i.e. Figure 4 The SBC (Single Board Computer) in the system is electrically connected to the DC to DC converter and the voltage regulator, and the single board computer is electrically connected to the ICU and the MCU respectively.
[0049] In some embodiments of the present invention, the driving board 101 also includes a DC-to-DC converter and a linear chip, the DC-to-DC converter is electrically connected to the positive poles of the multiple light-emitting diode units, and the voltage regulator is electrically connected to the negative poles of the multiple light-emitting diode units through the linear chip.
[0050] In this embodiment, if Figure 4 As shown, the driving board 101 also includes a DC to DC converter (i.e. Figure 4 The DC / DC BUCK in the DC / DC converter and the multiple light-emitting secondary units (in the DC / DC BUCK in the DC / DC converter) arranged on the flexible printed circuit board 103 Figure 4Among them, multiple light-emitting diode units form a display array, that is, an LED ISD (Light Emitting Diode Intelligent Sign Display). The positive electrodes of the LED ISD are electrically connected to provide a stable output voltage to the light-emitting diode units; the voltage regulator is electrically connected to the negative electrodes of multiple light-emitting diode units through a linear chip, and one linear chip corresponds to one light-emitting diode unit, so as to achieve precise control of the light-emitting diode units.
[0051] The inner lamp cover 2 is arranged in the light-emitting direction of the multiple light-emitting diode units;
[0052] In some embodiments of the present invention, the inner lamp cover 2 is injection-molded from a plastic material and made by adding an optical diffusing agent.
[0053] In practical applications, the inner lamp cover 2 can be made by adding no more than 10% of the optical diffusing agent. The optical diffusing agent plays a role in reducing the graininess of the display pattern or animation of the vehicle lamp structure and improving the fullness and uniformity of the light emission of each light-emitting diode unit.
[0054] In practical applications, the inner lamp cover 2 can be a two-color inner lamp cover, that is, an inner lamp cover composed of a transparent color and a black color. The transparent color part corresponds to each light-emitting diode unit, and the black part except the transparent color part covers the area between adjacent light-emitting diode units to reduce the light leakage phenomenon between the light-emitting diode units. Its front view is as Figure 5 shown.
[0055] In some embodiments of the present invention, the light-emitting diode module 1 is further provided with a first mounting hole 104, and the inner lamp cover 2 is further provided with a second mounting hole 201, and the first mounting hole 104 and the second mounting hole 201 match each other.
[0056] In this embodiment, as Figure 1 shown, the first mounting hole 104 and the second mounting hole 201 match each other. When assembling the vehicle lamp structure, a screw passes through the first mounting hole 104 and the second mounting hole 201 and is fixed by the screw, so that the light-emitting diode module 1 and the inner lamp cover 2 are installed and fixed.
[0057] The light-shielding bracket 3 is arranged on the side of the inner lamp cover 2 away from the light-emitting diode module 1, and the light-shielding bracket 3 is made by vacuum aluminizing;
[0058] In this embodiment, the light-shielding bracket 3 can be injection-molded from a plastic material and then vacuum aluminized for a second time. The light-shielding bracket 3 can isolate the uncontrollable interfering light emitted through the inner lamp cover 2, further reducing the light crosstalk rate between the light-emitting diode units, that is, the LED particles. Vacuum aluminizing the light-shielding bracket 3 can improve the display brightness of the light-emitting diode units, thereby enhancing the brightness and clarity of the displayed pattern or animation, and increasing its visible range, so that pedestrians passing by from the side of the vehicle body can clearly see the pattern or animation displayed by the vehicle lamp.
[0059] In some embodiments of the present utility model, the light-shielding bracket 3 is a grid structure, and each grid of the light-shielding bracket 3 matches each light-emitting diode unit.
[0060] In this embodiment, as Figure 6 shown, one grid in the light-shielding bracket 3 corresponds to one light-emitting diode unit, and adjacent light-emitting diode units are further separated by the grid, which can effectively prevent light crosstalk and light leakage between the light-emitting diode units.
[0061] The decorative ring 4 is arranged on the side of the light-shielding bracket 3 away from the inner lamp cover 2, and the decorative ring 4 is also provided with a plurality of transparent sheets 401, and an optical pattern 403 is arranged on the side of the transparent sheet 401 close to the light-shielding bracket 3.
[0062] In this embodiment, as Figure 2 shown, the transparent sheet 401 is a light guide structure for guiding the light emitted by a plurality of light-emitting diode units arranged on the flexible printed circuit board 103. Each transparent sheet 401 corresponds to each light-emitting diode unit one by one. The light passes through the inner lamp cover 2 and the light-shielding bracket 3 in sequence, and then is emitted to the outside of the vehicle lamp structure through the transparent sheet 401; the optical pattern 403 is arranged on the side of the transparent sheet 401 close to the light-shielding bracket 3, that is, the inner surface of the transparent sheet 401. The optical pattern 403 can be a pattern such as a pattern, which can refract the passing light, thereby increasing the viewing angle of the pattern or animation displayed by the vehicle lamp structure, and at the same time reducing the loss of light energy.
[0063] In practical applications, since the viewing angle of the pattern or animation displayed by the vehicle lamp structure is increased, the design of the entire vehicle lamp structure can be not limited to a flat or nearly flat structure, but can be designed as a curved surface structure with a certain curvature, improving the creativity of the lamp shape design.
[0064] In some embodiments of the present utility model, the decorative ring 4 is also provided with a black sheet 402, and the black sheet 402 is located between adjacent transparent sheets 401.
[0065] In this embodiment, as Figure 2 or Figure 7As shown, the black sheet 402 is disposed between adjacent transparent sheets 401. The black sheet 402 can further isolate the light leakage between the light-emitting diode units, making the pattern or animation displayed by the vehicle lamp structure clearer, thereby improving its display effect.
[0066] In some embodiments of the present invention, the light-shielding bracket 3 is further provided with a tenon structure, and the decorative ring 4 is further provided with a tenon groove. The tenon structure and the tenon groove are matched with each other.
[0067] In this embodiment, by embedding the tenon structure of the light-shielding bracket 3 into the tenon groove of the decorative ring 4, the light-shielding bracket 3 can be limited and fixed on the decorative ring 4.
[0068] In some embodiments of the present invention, an assembly process of the above vehicle lamp structure is further provided, which is specifically as follows:
[0069] First, the flexible printed circuit board 103 is fixed to one side of the fixed bracket 102 by thermal riveting, and then the driving board 101 is fixed to the other side of the fixed bracket 102 by screws. The driving board 101, the fixed bracket 102, and the flexible printed circuit board 103 form a small printed circuit board assembly, that is, the light-emitting diode module 1.
[0070] Further, through the first mounting hole 104 and the second mounting hole 201, the light-emitting diode module 1 and the inner lamp cover 2 are installed and fixed by screws and nuts. The inner lamp cover 2 needs to be installed on one side of the light-emitting direction of multiple light-emitting diode units.
[0071] Further, the light-shielding bracket 3 is installed and fixed to the whole formed by the light-emitting diode module 1 and the inner lamp cover 2 through the screw posts on the light-emitting diode module 1, and is limited and fixed to the decorative ring 4 through the tenon structure, and then the whole formed by the light-emitting diode module 1, the inner lamp cover 2, and the light-shielding bracket 3 is installed and fixed to the decorative ring 4 by screws.
[0072] In some embodiments of the present invention, a vehicle is further provided, and the vehicle includes the vehicle lamp structure as described above.
[0073] The embodiments of the present invention have the following advantages: through the inner lamp cover 2 and the light-shielding bracket 3 of the present invention, the light leakage phenomenon between multiple light-emitting diode units can be effectively reduced. At the same time, when the light emitted by the light-emitting diode units passes through the light-shielding bracket 3 made of vacuum aluminizing, its light emission rate can be increased, making the pattern displayed by the light-emitting diode module 1 clearer and obtaining a larger viewing angle; further, when the light passes through the optical texture 403 of the transparent sheet 401 provided on the decorative ring 4, refraction occurs, which can further increase the viewing angle of the pattern and effectively improve the display effect of the vehicle lamp.
