[0047] Example 1:

[0048] like Figure 1 and Figure 2 As shown, this embodiment also provides a vehicle light guide based on a light-guiding liquid, including: a liquid light guide module, a liquid driving module, and a light source module; the liquid light guide module includes: a hollow transparent tube 3 and a light-guiding liquid 4, the light-guiding liquid 4 is inside the hollow transparent tube 3, and the light-guiding liquid 4 can flow inside the hollow transparent tube 3; the hollow transparent tube 3 is connected to the liquid driving component, which can drive the light-guiding liquid 4 to circulate within the hollow transparent tube 3; the light emitted by the light source module shines on the light-guiding liquid 4, and the flowing water animation effect is achieved as the light-guiding liquid 4 circulates within the hollow transparent tube 3. The hollow transparent tube 3 is evacuated to a vacuum and then filled with the light-guiding liquid 4.

[0049] The liquid drive module includes a CNC water pump 5 and an electronic control integration unit 8. The electronic control integration unit 8 is connected to the CNC water pump 5, which is connected to the hollow transparent tube 3. The CNC water pump 5 pressurizes and drives the light-guiding liquid 4 inside the hollow transparent tube 3 by receiving control signals from the electronic control integration unit 8. The headlight guide also includes a motor 10. The motor 10 drives the electronic control integration unit 8, which in turn pressurizes the light-guiding liquid 4 using the CNC water pump 5. The motor 10 can be a stepper motor or a DC motor.

[0050] The motor 10 provides a stable power supply to the electronic control integrated circuit 8, so that the electronic drive integrated circuit 8 can send signals to the CNC water pump to change the water pump pressure to achieve the effect of controllable flow rate and adjustable water flow speed.

[0051] The hollow transparent tube 3 includes: a first straight tube section 301, a spiral section 302, and a second straight tube section 303; one end of the first straight tube section 301 serves as a first light-incident end 304, and the other end of the first straight tube section 301 is connected to one end of the spiral section 302; one end of the second straight tube section 303 serves as a second light-incident end 305, and the other end of the second straight tube section 303 is connected to one end of the spiral section 302; the first straight tube section 301 is connected to a CNC water pump 5 via a first connecting pipe 306, with the connection position adjacent to the first light-incident end 304; the second straight tube section 303 is connected to the CNC water pump 5 via a second connecting pipe 307, with the connection position adjacent to the second light-incident end 305.

[0052] The headlight guide also includes: a main trim frame 1, a fixed bracket 2, and a main support 7; a first straight tube 301 and a second straight tube 303 are mounted on the main trim frame 1, and the main trim frame 1 covers the area where the spiral part 302 is located; the main trim frame 1 is mounted on the fixed bracket 2 via the main support 7; a CNC water pump 5, an electronic control integration 8, and an adapter 9 are mounted on the fixed bracket 2.

[0053] The main decorative frame 1 is a visible decorative element that conceals the internal structural components. The curved shape is designed to save space and maximize the flow of the visible water effect.

[0054] This embodiment uses a hollow transparent tube in conjunction with a light-guiding liquid to achieve a flowing animation of light guiding, thus achieving a free-form design for the flowing effect of car lights.

[0055] This embodiment uses straight tubes and spiral tubes to create a richer and more flexible dynamic flow effect, highlighting the free and varied flow shape of the light guide liquid under the blow molding process. Traditional light guides cannot achieve similar shape designs.

[0056] The flow rate of the light-guiding liquid only needs to be below the pressure threshold that the transparent tube can withstand, and the flow rate can be adjusted automatically by a CNC hydraulic water pump.

[0057] Example 2:

[0058] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0059] This embodiment provides a vehicle light guide based on a light-guiding liquid, including a main trim frame 1, a fixing bracket 2, a hollow transparent tube 3, a light-guiding liquid 4, a CNC water pump 5, an LED board 6, a main bracket 7, an electronic control integration 8, an adapter 9, and a motor 10.

[0060] The CNC water pump 5 is pre-installed on the fixed bracket 2, the electronic control integrated circuit 8 is installed on the fixed bracket 2, and the LED board 6 is installed on the adapter 9 to form an adapter assembly. The adapter assembly is then installed on the fixed bracket 2. The electronic control integrated circuit 8 is connected to the CNC water pump 5 and the LED board 6 respectively. After the hollow transparent tube 3 is evacuated, light-guiding liquid 4 is injected to form a liquid light guide assembly. The liquid light guide assembly is then installed on the main decorative frame 1. The main decorative frame 1 is then installed on the main support 7. The liquid light guide assembly is then snapped onto the adapter 9, and the main support 7 is then installed on the fixed bracket 2.

[0061] Working principle:

[0062] When the water flow effect is activated, motor 10 drives electronic control integration 8, and electronic control integration 8 CNC water pump 5 pressurizes the liquid light guide assembly, so that the light guide liquid 4 in the hollow transparent tube 3 is under pressure and circulates in the tube. LED board 6 emits light and illuminates the light guide liquid 4, so the light guide liquid 4 can be observed moving and emitting light in the hollow transparent tube 3, thus realizing the effect of water flow animation.

[0063] Furthermore, the motor 10 can be either a stepper motor or a DC motor.

[0064] Furthermore, the motor 10 can be replaced with a power source such as a hydraulic rod or gear.

[0065] Furthermore, the CNC water pump 5 can be replaced with a booster valve.

[0066] This embodiment solves the problem that light guides cannot achieve dynamic water flow effects by using a hollow transparent tube, light-guiding liquid, and a CNC water pump, thus realizing the unique water flow animation of the car lights and the autonomous switching of the water flow rate.

[0067] This embodiment solves the problem of the uniformity of light guide shapes by using hollow transparent tubes produced by blow molding, and realizes the free diversification of the appearance structure of automotive light guides.

[0068] Conventional light guide structures cannot achieve flowing water animation effects. This embodiment can achieve flowing water effects and adjust the flowing water animation rate by controlling the water pump pressure, resulting in more diverse variations.

[0069] Conventional light guides have a rigid and monotonous appearance. This embodiment uses a hollow transparent tube made by blow molding, which allows for free design of the transparent tube shape and makes the movement trajectory of the flowing water effect diverse and variable.

[0070] This invention uses a hollow transparent tube in conjunction with a light-guiding liquid to achieve a flowing animation of light, thus enabling free design of flowing water effects for car lights.
