[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0029] Referring to Figures 1 to 6 As shown, a dual-light lens automotive headlight is provided, including a housing 1. One end of the housing 1 is fixedly installed with a lens 2, and the other end of the housing 1 is fixedly installed with a low-beam reflecting cup 11. One side of the low-beam reflecting cup 11 is provided with a low-beam lamp board 12, and the low-beam lamp board 12 is fixedly arranged in the housing 1. A high-beam heat dissipation block 18 is arranged in the housing 1. A high-beam lamp board 13 is arranged on the high-beam heat dissipation block 18, and a high-beam reflecting cup 14 is fixedly arranged on the high-beam heat dissipation block 18. The high-beam heat dissipation block 18 is arranged on the side of the low-beam lamp board 12 away from the low-beam reflecting cup 11. A first cooling fan 3 is arranged on the side of the high-beam heat dissipation block 18 away from the low-beam lamp board 12, and the first cooling fan 3 is arranged in the housing 1. A high-beam and low-beam switching mechanism 4 is fixedly arranged in the housing 1, and the high-beam and low-beam switching mechanism 4 is arranged between the lens 2 and the high-beam lamp board 13.

[0030] In this embodiment, when the low-beam lamp board 12 is turned on, the light is emitted to the low-beam reflecting cup 11 on one side, and then passes through the low-beam reflecting cup 11 and is emitted to the lens 2 to form low-beam light. The high-beam and low-beam switching mechanism 4 is arranged between the lens 2 and the high-beam lamp board 13. By using the high-beam and low-beam switching mechanism 4 and turning on the high-beam lamp board 13, the light of the high-beam lamp board 13 is emitted to the high-beam reflecting cup 14 on one side, and then emitted from the lens 2 to form high-beam light. The high-beam and low-beam switching mechanism 4 can switch between high-beam light and low-beam light. Since a large amount of heat is generated when the high-beam lamp board 13 emits light, a high-beam heat dissipation block 18 is installed on the high-beam lamp board 13 to facilitate the conduction of heat from the high-beam lamp board 13 to the high-beam heat dissipation block 18 for heat dissipation. At the same time, a first cooling fan 3 is also installed on one side of the high-beam heat dissipation block 18 to dissipate heat from the high-beam heat dissipation block 18.

[0031] In one embodiment of the present utility model, the high-beam heat dissipation block 18 is provided with an inclined surface 181, and the inclined surface 181 is inclined in the direction from the high-beam and low-beam switching mechanism 4 to the first cooling fan 3. The high-beam lamp board 13 is fixedly arranged on the inclined surface 181. The inclined surface 181 has a certain slope to ensure that the position of the high-beam lamp board 3 is exactly installed at the required position, and this installation structure can reduce the length of the product and reserve a position for the installation and heat dissipation of the first cooling fan 3.

[0032] Embodiment 1:

[0033] As Figures 1 to 3 shown, a second cooling fan 5 is detachably installed at one end of the housing 1 away from the lens 2. A fan cover 51 is fixedly arranged on one side of the second cooling fan 5 away from the housing 1, which plays a role in protecting the second cooling fan 5. The housing 1 is installed with the second cooling fan 5 mainly to avoid the reduction of heat caused by the occlusion of a position on the cooling fan, which affects heat dissipation. The double-fan structure can improve the heat dissipation efficiency. The second cooling fan 5 is arranged at one end of the housing 1 to dissipate heat from the end of the whole housing 1 close to the second cooling fan 5. When this dual-beam lens automotive headlight is installed on a vehicle model with a small internal space, the second cooling fan 5 can be detached separately to reduce the overall length of this dual-beam lens automotive headlight, facilitating installation.

[0034] Embodiment 2:

[0035] As Figures 4 to 5 shown, a buckle bracket 6 is detachably installed at one end of the housing 1 away from the lens 2. The buckle bracket 6 includes a connecting frame 61 and a plurality of mounting buckles 62. Threads are provided on the connecting frame 61, and the plurality of mounting buckles 62 are threadedly connected to the connecting frame 61. A limiting member 63, a plurality of different types of mounting buckles 62, and a locking nut 64 are sequentially sleeved on the connecting frame 61. The function of the limiting member 63 is to keep the plurality of mounting buckles 62 locked and fixed when the locking nut 64 is tightened. When installation is required, the locking nut 64 is unscrewed and the corresponding mounting buckle is used for installation. The connecting frame 61 is provided with various mounting buckles 62, which is convenient for different mounting buckles to be installed on different vehicle models.

[0036] Embodiment 3:

[0037] As Figure 6 shown, there is no second cooling fan 5 or buckle bracket 6 installed at one end of the housing 1 away from the lens 2, and it can be directly installed and used. The housing 1 in this embodiment has a smaller size than the housing in Embodiment 1 or Embodiment 2, and the installation is more convenient, which is used for installation in small-size positions.

[0038] In one embodiment of the present utility model, the high-low beam switching mechanism 4 includes a light-shielding sheet 41 and an electromagnet 42. The electromagnet 42 is fixedly installed in the housing 1, and the light-shielding sheet 41 is movably arranged on the electromagnet 42. The light-shielding sheet 41 can block the light of the high-beam lamp board 13 to form low-beam light. The light-shielding sheet 41 is installed on the housing 1, and the light forms low-beam light through the light-shielding sheet 41. The light-shielding sheet 41 moves up and down by the telescopic movement of the electromagnet 42, thereby forming the function of switching between high and low beams. When the light-shielding sheet 41 rises, it blocks the light of the high-beam lamp board 13 to form low beam; when the light-shielding sheet 41 descends, the light of the high-beam lamp board 13 is unblocked to form high beam. Finally, the required light pattern is projected through the lens 2, optimizing the light pattern effect and meeting the driving experience of customers' high and low beams.

[0039] In one embodiment of the present utility model, a driving board 8 is arranged inside the housing 1. The driving board 8 is arranged between the first cooling fan 3 and the high-beam lamp board 13, and is electrically connected to the low-beam lamp board 12 and the high-beam lamp board 13 through wires. The driving board 8 controls the switches of the low-beam lamp board 12 and the high-beam lamp board 13. At the same time, the first cooling fan 3 also cools the driving board 8. The installation position of the driving board 8 makes the most of the space of the housing 1, which helps to reduce the size of the dual-beam lens automotive headlamp.

[0040] In one embodiment of the present utility model, a decorative cover 7 is fixedly arranged on the side of the low-beam reflecting cup 11 away from the low-beam lamp board 12. The decorative cover 7 covers the low-beam reflecting cup 11. The decorative cover 7 protects the low-beam reflecting cup 11 from being damaged, and at the same time hides the installation structure inside the housing 1, playing a role in beautifying the appearance.

[0041] In one embodiment of the present utility model, the housing 1 includes a lens bracket 15, a metal body 16 and a bottom cover 17. The lens bracket 15 is fixedly connected to the metal body 16 by bolts, and the bottom cover 17 is fixedly connected to the metal body 16 by bolts. The bottom cover 17 is arranged on one side of the first cooling fan 3. The heat generated by the low-beam lamp board 12 can be conducted to the heat dissipation block through the metal body 16 for heat dissipation, or directly dissipated on the metal body 16. The second cooling fan 5 is installed on one side of the metal body 16 to cool the entire metal body 16. At the same time, the heat of the high-beam heat dissipation block 18 can also be conducted to the metal body 16 for heat dissipation. Preferably, the metal body 16 is made of aluminum material, which has low cost and strong heat conductivity.

[0042] Preferably, a heat dissipation notch 151 is formed on the side of the lens bracket 15 close to the metal body 16, which helps the heat to dissipate from the heat dissipation notch 151 and allows the external cold air to enter, so as to quickly achieve the heat dissipation effect.

[0043] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
