Abstract
Description
Technical Field
[0001] The present invention relates to a technical improvement of automobile driving, in particular to a taillight with a functional upgraded hard-line design. Background Art
[0002] As the world evolves, demands for automotive functionality become increasingly stringent, and lighting's welcome functions are becoming increasingly diverse and complex. However, to maintain a constant sense of freshness, lighting suppliers are adding even more diverse welcome functions. To ensure instant refreshability, they often design lighting circuits using CAN / LIN communication. This allows for instant refresh of the welcome function. However, while traditional hard-wired drive circuits are less expensive than CAN / LIN communication designs, they lack the ability to refresh the welcome function. Consequently, the lighting often retains a single welcome function from production to end-of-life, resulting in a relatively limited functionality. Summary of the Invention
[0003] In order to solve the above problems, the present invention provides a taillight with a functional upgrade hard-wire design solution, which can realize the welcome program upgrade while continuing to use the low-cost hard-wire drive circuit, making the lamp function more diversified.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a taillight with a hard-wired design scheme for functional upgrades, comprising a connector, a wiring harness, a driver board and a light board, wherein the driver board is provided with a LIN upgrade module and a driver module, and the light board is provided with a number of LED units, each LED unit is connected to the driver module in the driver board, and the driver module is also connected to the connector through a wiring harness, and the connector is also connected to the driver module through the wiring harness and the LIN upgrade module.
[0005] Preferably, a rubber sleeve is further included, and the rubber sleeve is wrapped in the wiring harness.
[0006] Preferably, the vehicle further comprises a lamp housing, wherein the lamp panel is arranged in the lamp housing.
[0007] Preferably, a light-emitting mask is further included, and the light-emitting mask encapsulates the light panel in the vehicle lamp housing.
[0008] Preferably, the connector can be connected to the MCU module of the vehicle body.
[0009] The present invention's beneficial effects: The taillights, featuring a hard-wired design for functional upgrades, can transmit a LIN upgrade signal from the vehicle body to the LIN upgrade module on the driver board via connectors and wiring harnesses. The LIN upgrade module then processes the signal into microcontroller language and transmits it to the driver module, replacing the original program within the driver module's MCU. When the vehicle body supplies power to the driver module via the connectors and wiring harnesses and sends a welcome signal, the driver module illuminates the LED light panel according to the updated program within the MCU, creating a welcoming effect.

[0013] The preferred embodiments of the present invention are described below. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0014] A taillight with a functional upgrade hard-wire design, including a connector 1, a wiring harness 2, a driver board 4 and a light board 5, wherein the driver board 4 is provided with a LIN upgrade module 41 and a driver module 42, and the light board 5 is provided with a plurality of LED units 6, each LED unit 6 being connected to the driver module 42 in the driver board 4, and the driver module 42 being further connected to the connector 1 via the wiring harness 2, and the connector 1 being further connected to the driver module 42 via the LIN upgrade module 41 via the wiring harness 2; further comprising a rubber sleeve 3, the rubber sleeve 3 being wrapped in the wiring harness 2; further comprising a lamp housing 7, the light board 5 being provided in the lamp housing 7; further comprising a light-emitting mask 8, the light-emitting mask 8 encapsulating the light board 5 in the lamp housing 7; the connector 1 being connectable to the MCU module 9 of the vehicle body.
[0015] In practice, when the lamp is powered on, it first checks to see if it has received the LIN upgrade program sent by the vehicle body. If so, the lamp converts the upgrade program into microcontroller language via the LIN upgrade module and then inputs it into the MCU, replacing the original program within the MCU. If the upgrade program is not received, no further processing is performed and the next step is advanced. The lamp then determines whether the vehicle body is providing power and transmitting a welcome signal. If so, the internal driver module activates the LED panels, illuminating them sequentially according to the welcome program, achieving the desired welcome effect.
[0016] The above are preferred embodiments of the present invention. Those skilled in the art to which the present invention belongs can also change and modify the above embodiments. Therefore, the present invention is not limited to the above specific embodiments. Any obvious improvements, replacements or modifications made by those skilled in the art on the basis of the present invention fall within the scope of protection of the present invention.
