Description

Technical Field

[0001] This utility model relates to the field of automotive fog light technology, specifically to a vehicle fog light with a defogging function. Background Technology

[0002] Traditional automotive fog lights generally consist of a fog light housing, a flat lens, a lens bracket, an LED light source, an aluminum heat sink, and a fan. The flat lens is fixed to the front of the fog light housing by the lens bracket, and the fan is mounted at the rear of the fog light housing. The LED light source and the aluminum heat sink are installed inside the fog light housing. The LED light source is mounted on top of the aluminum heat sink, and the heat generated by the LED light source is conducted to the aluminum heat sink, and then dissipated through the aluminum heat sink and the fan. Existing automotive fog lights have the following problems during use:

[0003] 1) Existing car fog lights are external lights. External fans are prone to damage due to mud and sand, resulting in limited heat dissipation for car fog lights. In addition, the inside of car fog lights is a relatively closed space with poor ventilation. During the car's operation, the external airflow carries away heat, while the internal space remains relatively hot due to the large temperature difference between the inside and outside. This causes fogging to form on the lens, thereby reducing the product's lighting effect.

[0004] 2) Existing fog lights use flat lenses, which have low light brightness and insufficient penetration in rainy and foggy weather, making it difficult for drivers to drive in foggy conditions. Utility Model Content

This dissipates the heat generated by the light source mechanism during operation, reduces the internal heat of the vehicle fog light, and includes a vent valve to balance the air pressure inside and outside the vehicle fog light, thereby extending the lifespan of the vehicle fog light and improving its reliability and practicality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

A vent valve is provided at the bottom of the main heat sink and is threadedly connected to the bottom of the main heat sink. The defogging turbine fan is fixed to the upper part of the auxiliary heat sink and located on one side of the bi-xenon lens. The driver is installed inside the auxiliary heat sink and located on one side of the defogging turbine fan. The driver is also electrically connected to the defogging turbine fan and the high beam module. The defogging turbine fan has an air inlet on the side wall facing the main heat sink and an air outlet on the side wall facing the bi-xenon lens.

[0008] Furthermore, a high beam heat sink is fixed below the high beam module and installed inside the main heat sink. A high beam reflector is fixed at the upper end of the high beam module, with the opening of the high beam reflector aligned with the lower hemisphere of the bi-xenon lens. A low beam reflector is covered above the low beam module, with the opening of the low beam reflector aligned with the upper hemisphere of the bi-xenon lens. The high / low beam switching mechanism is installed between the high beam module and the bi-xenon lens to achieve switching between high and low beams.

[0009] Furthermore, the high beam module includes high beam LED beads and a high beam light panel, the high beam LED beads are fixed to the upper end of the high beam light panel, and the high beam light panel is also electrically connected to the driver. The low beam module includes low beam LED beads and a low beam light panel, the low beam LED beads are fixed to the upper end of the low beam light panel.

[0010] Furthermore, the high / low beam switching mechanism includes a lifting drive assembly and a light-blocking flap, the light-blocking flap being installed above the lifting drive assembly and positioned between the high beam module and the bi-xenon lens.

[0011] Furthermore, the outer surface of the main heat sink is provided with a plurality of first heat sink fins, which are fixed to the outer surface of the main heat sink at intervals. The spacing between adjacent first heat sink fins forms a first airflow channel for airflow.

[0012] Furthermore, the outer surface of the auxiliary heat sink is provided with a plurality of second heat sink fins, which are fixed to the outer surface of the auxiliary heat sink at intervals. The spacing between adjacent second heat sink fins forms a second airflow channel for airflow.

[0013] Furthermore, the automotive fog light includes a retaining ring, and the bi-xenon lens is fixed to one end of the main heat sink and the auxiliary heat sink via the retaining ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) This utility model's automotive fog light includes a main heat sink, an auxiliary heat sink, a defogging turbine fan, a driver, a light source mechanism, a bi-xenon lens, and a high / low beam switching mechanism.

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the present invention will be illustrated through embodiments, and other aspects, features, and advantages of the present invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0029] Example 1:

[0030] like Figures 1-6As shown, this utility model provides a vehicle fog light with a defogging function. The fog light includes a main heat sink 1, an auxiliary heat sink 2, a defogging turbine fan 3, a driver 9, a light source mechanism 4, a bi-xenon lens 5, and a high / low beam switching mechanism 6. The auxiliary heat sink 2 is installed above the main heat sink 1. Specifically, the auxiliary heat sink 2 has a semi-cylindrical structure. The bi-xenon lens 5 is fixed to the front pillar end of the main heat sink 1 and the auxiliary heat sink 2. The cross-section of the auxiliary heat sink 2 is semi-circular. The auxiliary heat sink 2 is installed on the upper end of the main heat sink 1 by bolts 23. A waterproof sealing ring 15 is fixed at the installation point of the auxiliary heat sink 2 and the main heat sink 1. The bi-xenon lens 5 is fixed to one end of the main heat sink 1 and the auxiliary heat sink 2. The light source mechanism 4 is installed inside the main heat sink 1. The high / low beam switching mechanism 6... Installed inside the main heat sink 1 and located between the light source mechanism 4 and the bi-beam lens 5, the light source mechanism 4 includes a low beam module 41 and a high beam module 42. The low beam module 41 is installed on one side above the high beam module 42. The bottom end of the main heat sink 1 is provided with a vent valve 11, which is threaded to the bottom end of the main heat sink 1. A waterproof ring 12 is fitted around the connection between the vent valve 11 and the main heat sink 1. The defogging turbine fan 3 is fixed inside the auxiliary heat sink 2 at the upper end and located on one side of the bi-beam lens 5. The driver 9 is installed inside the auxiliary heat sink 2 and located on one side of the defogging turbine fan 3. The driver 9 is also electrically connected to the defogging turbine fan 3 and the high beam module 42. The defogging turbine fan 3 has an air inlet 31 on the side wall facing the main heat sink 1 and an air outlet 32 ​​on the side wall facing the bi-beam lens 5. The vehicle fog light of this utility model also includes a fixing ring 7. The bi-xenon lens 5 is fixed to one end of the main heat sink 1 and the auxiliary heat sink 2 by the fixing ring 7. The bi-xenon lens 5 is tightly fixed to the front pillar end of the main heat sink 1 and the auxiliary heat sink 2 by the fixing ring 7.

[0031] This invention incorporates a defogging turbine fan 3 inside the auxiliary heat sink 2. The defogging turbine fan 3 has an air inlet 31 on its side wall facing the main heat sink 1 and an air outlet 32 ​​on its side wall facing the bi-xenon lens 5. A driver 9 drives the high beam module 42 and the defogging turbine fan 3, causing the defogging turbine fan 3 to draw air upwards through the air inlet 31. After internal pressurization, the air is discharged from the air outlet 32 ​​and directed towards the bi-xenon lens 5, accelerating airflow on the surface of the bi-xenon lens 5 and rapidly evaporating the fog. The driver 9 in this invention not only drives the high beam module 42 but also powers the defogging turbine fan 3. The fog light is equipped with a main heat sink 1 and an auxiliary heat sink 2. The main heat sink 1 and the auxiliary heat sink 2 provide a dual heat dissipation effect, which can dissipate the heat generated by the light source mechanism 4 during operation, reduce the internal heat of the fog light, and prevent excessive internal heat. A vent valve 11 is provided to allow dry external air to enter, keeping the inside of the main heat sink 1 dry and clean, reducing corrosion and damage caused by humid environments, and extending the service life of the fog light. During the use of the fog light, the vent valve 11 can help balance the internal and external pressure, effectively reducing fogging inside the fog light, improving the lighting effect and safety of the fog light. In addition, the vent valve 11 can effectively prevent moisture (such as rainwater and dew) from entering the inside of the main heat sink 1.

[0032] The high beam module 42 of this invention has a high beam heat sink 8 fixed at its lower part, which is installed inside the main heat sink 1. A high beam reflector 44 is fixed at the upper end of the high beam module 42, with its opening aligned with the lower hemisphere 52 of the bi-xenon lens 5. A low beam reflector 43 is mounted on top of the low beam module 41, with its opening aligned with the upper hemisphere 51 of the bi-xenon lens 5. A high / low beam switching mechanism 6 is installed on the high beam module. The module 42 and the bi-xenon lens 5 enable switching between high and low beams. The high beam module 42 includes high beam LED beads 421 and a high beam light panel 422. The high beam LED beads 421 are fixed to the upper end of the high beam light panel 422, which is also electrically connected to the driver 9. The low beam module 41 includes low beam LED beads 411 and a low beam light panel 412, with the low beam LED beads 411 fixed to the upper end of the low beam light panel 412. The bi-xenon lens 5 is made of optical PC material and has an upper hemisphere 51 and a lower hemisphere 52, which are integrated into one piece. A high beam heat sink 8 is fixed below the high beam module 42. The high beam heat sink 8, in conjunction with the main heat sink 1 and the auxiliary heat sink 2, provides multiple cooling solutions for the heat generated by the light source mechanism 4, greatly improving the heat dissipation effect and accelerating the cooling efficiency. In specific implementation, the high beam reflector 44 of this utility model is a bowl-shaped structure with an open front end. The high beam reflector 44 is fixed upside down on the upper end of the high beam module 42, covering the high beam module 42. The high beam reflector 44 is also located on one side of the low beam module 41. The low beam reflector 43 is a bowl-shaped structure with an open front end. The low beam reflector 43 is fixed upside down on the upper end of the low beam module 41, covering the low beam module 41. The low beam reflector 43 is also installed above the high beam reflector 44.

[0033] In this embodiment of the utility model, a first cavity is formed in the main heat sink 1 and a second cavity is formed in the auxiliary heat sink 2. The first cavity in the main heat sink 1 facilitates the fixation of the light source mechanism 4, the high beam / low beam switching mechanism 6, and the high beam heat sink 8. The second cavity in the auxiliary heat sink 2 facilitates the fixation of the defogging turbine fan 3. Furthermore, the first and second cavities can form channels that allow airflow or gas circulation, making it easier for the defogging turbine fan 3 to draw air from bottom to top.

[0034] The high / low beam switching mechanism 6 of this utility model includes a lifting drive assembly 62 and a light-blocking plate 61. The light-blocking plate 61 is installed above the lifting drive assembly 62 and is disposed between the high beam module 42 and the bi-xenon lens 5. In a specific implementation, the lifting drive assembly 62 includes a fixed support plate 621 and an electromagnet 622. The fixed support plate 621 is installed on one side of the high beam heat sink 8, and the electromagnet 622 is installed on the fixed support plate 621. The light-blocking plate 61 is set as an arc plate structure. A connecting plate 611 is provided in the middle of the light-blocking plate 61. One end of the connecting plate 611 is connected to the middle of the light-blocking plate 61, and the other end of the connecting plate 611 is installed on the upper end of the push-pull rod 623 of the electromagnet 622. The light-blocking plate 61 is installed on the upper end of the push-pull rod 623 of the electromagnet 622 through the connecting plate 611. The electromagnetic coil of the electromagnet 622 is installed on the fixed support plate 621, and a return spring 624 is installed between the push-pull rod 623 of the electromagnet 622 and the electromagnetic coil. When the electromagnet 622 is energized and engaged, the push-pull rod 623 moves downward under the action of the electromagnetic coil of the electromagnet 622, thereby pulling the light-blocking switch 61 downward and putting the light-blocking switch 61 in the closed position. Conversely, when the electromagnet 622 is de-energized and disengaged, the push-pull rod 623 moves upward under the elastic action of the return spring 624, thereby pulling the light-blocking switch 61 upward and putting the light-blocking switch 61 in the open position. During the switching between high and low beams, simply controlling the engagement or disengagement of the electromagnet 622 can drive the light-blocking switch 61 to switch to the open and closed positions.

[0035] This invention features a plurality of first heat dissipation fins 13 on the outer surface of a main heat sink 1, which are fixed to the outer surface of the main heat sink 1 at intervals. The spacing between adjacent first heat dissipation fins 13 forms a first airflow channel 14 for airflow. Similarly, a plurality of second heat dissipation fins 21 are provided on the outer surface of an auxiliary heat sink 2, which are fixed to the outer surface of the auxiliary heat sink 2 at intervals. The spacing between adjacent second heat dissipation fins 21 forms a second airflow channel 22 for airflow. By providing the first heat dissipation fins 13 and the first airflow channel 14 on the outer surface of the main heat sink 1, and the second heat dissipation fins 21 and the second airflow channel 22 on the outer surface of the auxiliary heat sink 2, the heat generated by the internal light source mechanism 4 of the vehicle fog light can be quickly dissipated into the outside air, achieving efficient heat dissipation and preventing the heat generated by the light source mechanism 4 from remaining inside the main heat sink 1 and the auxiliary heat sink 2, thus extending the service life of the vehicle fog light.

[0036] like Figures 9-10 As shown, the working principle of this utility model automotive fog light is as follows:

[0037] 1. When the car's low beam headlights are turned on, the low beam LED beads 411 of the low beam module 41 illuminate. The light emitted by the low beam LED beads 411 is reflected by the low beam reflector 43. When the light passes through the high beam switching mechanism 6, part of the light is blocked, and then focused by the lower hemisphere 52 of the bi-xenon lens 5. At the same time, the high beam LED beads 421 of the high beam module 42 illuminate. The light emitted by the high beam LED beads 421 is reflected by the high beam reflector 44, and the light passes through... When the high beam / low beam switching mechanism 6 is used, some of the light rays are blocked. The light is then focused by the lower hemisphere 52 of the bi-xenon lens 5, which enhances the light intensity in the center area of ​​the low beam, thereby enhancing the lighting effect and forming a low beam pattern with a cutoff line. At the same time, the defogging turbine fan 3 works, drawing air from the bottom up. After internal pressurization, the air is discharged from the air outlet 32 ​​and blown onto the bi-xenon lens 5. This effectively balances the temperature difference between the inside and outside of the bi-xenon lens 5 and effectively prevents the bi-xenon lens 5 from fogging up.

[0038] 2. When the car turns on the high beam, while ensuring that "1" is working, the high beam switching mechanism 6 starts to work, opening the light blocking flap 61. The light in "1" that was blocked by the high beam LED beads 421 and the low beam reflector 43, as well as the light that was blocked by the high beam switching mechanism 6, is fully turned on, forming a high beam effect with a central strong light zone.

[0039] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0040] In the above embodiments, the vehicle fog light of this utility model balances the internal and external temperature difference of the bi-xenon lens 5 by embedding a defogging turbine fan 3 inside the auxiliary heat sink 2. This effectively prevents the bi-xenon lens 5 from fogging, improves the lighting effect of the vehicle fog light, and effectively prevents fog from affecting the lighting effect of the vehicle fog light. This makes it easier for the driver to see the road conditions and improves the safety of the driver when driving in rainy or foggy weather. When illuminating, the high / low beam switching mechanism 6 and the bi-xenon lens 5 can work together to realize the switching of the light source mechanism 4 from high to low beam. The heat generated during illumination can be dissipated through the heat sink shell and the auxiliary heat sink 2. The ventilation valve 11 is set to balance the internal and external air pressure of the vehicle fog light, which extends the service life of the vehicle fog light and improves the reliability and practicality of the vehicle fog light.

[0041] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
