DETAILED DESCRIPTION

[0027] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] During the driving process, the car often vibrates due to uneven roads and the engine itself. When the vibration is transmitted to the headlights, continuous or strong vibration may cause damage to the bulbs, especially headlights using LED light sources, which contain sensitive electronic components such as electronic control units (ECUs) and drivers. Vibration may cause poor contact of these electronic components, cracks in circuit boards or damage to chips, affecting the normal operation of the headlights. To this end, the present invention is improved by the following steps:

[0029] Embodiment 1: A car headlight with a seismic-resistant structure, combined with Figure 1-Figure 3As shown, it includes a fixing frame 1, the fixing frame 1 is rotatably connected to a reflective plate 11, the right side of the reflective plate 11 is used to reflect light, and the left side is used to install a car lamp. A fixing block 12 is fixedly connected to the upper side of the reflective plate 11, and a threaded rod 13 is threadedly connected to the upper side of the fixing frame 1. The threaded rod 13 is used to adjust the angle of the reflective plate 11. The right side of the threaded rod 13 is a spherical block, and the threaded rod 13 is slidably connected to the fixing block 12 through the spherical block thereon. The reflective plate 11 is provided with a fixing column 14, and the diameter of the fixing column 14 is smaller than that of the reflective plate 11. The inner diameter of the reflecting plate 11 is formed by a circuit board 15 fixedly connected to the right side of the fixing column 14, and two LED lamps 151 symmetrically distributed front and back are installed on the circuit board 15. The fixing column 14 is fixedly connected to a liquid capsule 16, and the liquid capsule 16 is used to reduce the vibration of the fixing column 14. The liquid capsule 16 is located on the right side of the fixing column 14, and the liquid capsule 16 is squeezed and matched with the reflecting plate 11. A groove corresponding to the liquid capsule 16 is opened on the left side of the reflecting plate 11. A clamping mechanism is provided on the rear side of the reflecting plate 11, and the clamping mechanism is used to fix the fixing column 14.

[0030] Combination Figure 2-Figure 5 As shown, the clamping mechanism includes a rotating member 2, which is slidably and rotatably connected to the left side of the fixed column 14. The rotating member 2 is connected to the fixed column 14 by a large annular block on the left and a small annular block on the right through an L-shaped plate connection assembly. The fixed column 14 is slidably connected to a sliding ring 21, and the outer ring of the sliding ring 21 is rotatably connected to a rotating ring 22. A circular hole is provided on the rotating ring 22, and a cylinder is fixedly connected to the right side of the small annular block on the rotating member 2. The rotating ring 22 is limitedly matched with the cylinder on the rotating member 2 through the circular hole thereon. Two limiting grooves 221 are provided in the reflecting plate 11. The limiting groove 221 consists of two straight grooves and an arc groove connecting the two straight grooves. The rotating ring 22 is provided with two protrusions. The two protrusions on the rotating ring 22 slide in the adjacent limiting grooves 221 respectively. The rotating ring 22 slides in the two limiting grooves 221 through the two protrusions thereon. A seal 23 is slidably connected to one side of the ring 21 close to the LED lamp 151. The seal 23 consists of a circular ring and circumferentially distributed cylinders. The cylinders are located on the right side of the circular ring and slide in the rotating ring 22. The fixed column 14 is provided with an annular cavity 24, which is connected to the liquid capsule 16 and filled with hydraulic oil. The seal 23 slides in the annular cavity 24 in a sealed manner. When the seal 23 moves to the right, the hydraulic oil in the annular cavity 24 is squeezed and the hydraulic oil is squeezed into the liquid capsule 16. A spring 25 is fixedly connected between the sliding ring 21 and the seal 23. The spring 25 is used to provide pressure for the liquid in the liquid capsule 16. A positioning ring 26 is fixedly connected to the fixed column 14. The positioning ring 26 is squeezed and matched with the reflector 11. The positioning ring 26 is used to locate the position of the fixed column 14 and the positioning ring 26 is in contact with the liquid capsule 16.

[0031] Combination Figure 2 and Figure 5As shown, the reflective plate 11 is slidably connected to the limit ring 3, and two square protrusions are arranged on the inner side of the limit ring 3. The two square protrusions on the limit ring 3 slide in adjacent limit grooves 221 respectively. A fixing rod 31 is fixedly connected to the upper side of the limit ring 3, and a U-shaped rod 32 is slidably connected to the upper side of the fixing frame 1. The U-shaped rod 32 is close to the threaded rod 13, and the right end of the U-shaped rod 32 and the fixing rod 31 are ball-jointed. The square protrusion on the inner side of the limit ring 3 is limitedly matched with the protrusion on the rotating ring 22. When the protrusion on the rotating ring 22 moves on the adjacent limit grooves 221, the protrusion on the rotating ring 22 gradually contacts with the adjacent square protrusion on the limit ring 3.

[0032] Before using the device, the device must be installed first. The installation process is as follows: the staff first places the fixing column 14 into the reflective plate 11, and the fixing column 14 drives the positioning ring 26 to move to the right until the positioning ring 26 contacts the reflective plate 11. Then the staff holds the rotating member 2 and continues to move to the right. During the movement of the rotating member 2 to the right, the rotating member 2 gradually contacts the rotating ring 22. Then the rotating member 2 is rotated. During the rotation of the rotating member 2, the cylinder on the rotating member 2 gradually enters the hole on the rotating ring 22. Then the rotating member 2 drives the rotating ring 22 to rotate, and the rotating ring 22 is During the rotation, the protrusion gradually corresponds to the limit groove 221, and then drives the rotating ring 22 to move to the right. The protrusion on the rotating ring 22 enters the limit groove 221 and slides along the straight groove on the limit groove 221. The rotating ring 22 drives the sliding ring 21 to move to the right. The sliding ring 21 drives the seal 23 to move to the right through the circumferentially distributed spring 25. The seal 23 moves to the right to squeeze the hydraulic oil in the annular cavity 24, so that the hydraulic oil enters the liquid capsule 16. The liquid capsule 16 swells under the pressure of the hydraulic oil, gradually contacts with the reflector 11, and squeezes the reflector 11.

[0033] When the liquid capsule 16 no longer bulges under the pressure of the reflective plate 11, the sliding ring 21 continues to move to the right. At this time, the spring 25 contracts until the protrusion on the rotating ring 22 corresponds to the annular groove of the limiting groove 221, and then the rotating ring 22 is rotated counterclockwise (from right to left). When the rotating ring 22 no longer moves, it stops. At this time, the protrusion on the rotating ring 22 contacts the adjacent square protrusion on the limiting ring 3, and then the rotating member 2 is reset.

[0034] After the fixing column 14 is fixed, the fixing column 14 is positioned by squeezing the positioning ring 26 through the liquid capsule 16 and the reflecting plate 11. The reflecting plate 11 and the fixing column 14 are fixedly connected through the rotating ring 22 and the liquid capsule 16. Under the support of the liquid capsule 16 and the rotating ring 22, there is a small gap between the fixing column 14 and the reflecting plate 11. When the car is vibrating while driving (the headlights are parallel to the horizontal plane at this time), if it is subjected to vertical vibrations, the force generated by the vibrations will first be transmitted to the liquid capsule 16. The liquid capsule 16 reduces the vibrations through the liquid therein, reduces the shaking of the fixing column 14, and further reduces the vibration force on the circuit board 15 and the LED lamp 151, thereby preventing the circuit board 15 and the LED from being damaged and extending the service life of the circuit board 15 and the LED. When subjected to left and right vibrations, the vibrations are transmitted to the liquid capsule 16, and the liquid absorbs the vibrations, thereby reducing the impact of the vibrations on the headlights.

[0035] When it is necessary to adjust the illumination direction of the car light, the staff rotates the threaded rod 13 to make the threaded rod 13 slide to the right on the fixing frame 1, and the ball on the right side of the threaded rod 13 drives the right side of the reflector 11 to rotate downward through the fixing block 12. At the same time, the ball on the right side of the threaded rod 13 slides in the fixing block 12, and the reflector 11 drives the parts thereon to rotate, thereby changing the illumination direction of the car light.

[0036] In the process of rotating the threaded rod 13, the reflective plate 11 rotates and drives the limit ring 3 to rotate upward. The limit ring 3 moves to the right during the rotation and drives the fixed rod 31, so that the right end of the fixed rod 31 tends to move to the right. Since the right end of the fixed rod 31 is ball-connected with the U-shaped rod 32, the fixed rod 31 moves to the left relative to the reflective plate 11 under the limitation of the fixed rod 31, thereby driving the limit ring 3 to move to the left relative to the reflective plate 11. During the movement of the limit ring 3, the spring 25 is gradually released (not completely released) and drives the rotating ring 22 to move to the left through the sliding ring 21. The protrusion on the rotating ring 22 is always in contact with the square protrusion on the limit ring 3. Since the spring 25 is released, the squeezing force of the seal 23 on the liquid in the liquid capsule 16 is relatively reduced.

[0037] After the threaded rod 13 is rotated to rotate the right side of the reflector 11 downward, the right side of the reflector 11 tilts downward. At this time, the supporting force of the liquid capsule 16 in the up and down directions is relatively reduced, and the reduced part is supported by the positioning ring 26. If the reflector 11 is subjected to downward vibration at this time, the vibration passes through the positioning ring 26 during the process of being transmitted to the fixed column 14, and is separated in the left and right directions of the positioning ring 26. After being vibrated, the positioning ring 26 moves to the left to squeeze the liquid capsule 16. On the basis of not changing the supporting effect on the fixed column 14, the pressure of the liquid in the liquid capsule 16 is reduced, thereby achieving a better effect of absorbing vibration.

[0038] The LED lamp 151 has the characteristics of long life and high safety, but the LED lamp 151 will generate a lot of heat when in use. Generally, the heat is dissipated to the outside through the metal sheet, and the efficiency of heat flow is low. The LED lamp 151 cannot be cooled quickly, and the heat dissipation effect is poor, which affects the service life of the LED lamp. For this reason, the present invention is improved by the following steps:

[0039] Embodiment 2: Based on Embodiment 1, Figure 6 and Figure 7 As shown, a cooling mechanism is also included, which is located in the fixed column 14. The cooling mechanism is used to cool the LED lamp 151. The cooling mechanism includes a transparent shell 4, which is fixed to the right side of the fixed column 14. The fixed column 14 is provided with a first guide groove 41 and a first guide cavity 42. The first guide groove 41 is located behind the circuit board 15. The first guide groove 41 is connected to the first guide cavity 42. The first guide cavity 42 is semicircular. The fixed column 14 is fixed with a heat dissipation shell 43 through circumferentially distributed metal tubes. The first guide cavity 42 is connected to the heat dissipation shell 43 through adjacent metal tubes. The heat dissipation shell 43 is located in the first guide cavity 4 2, the fixed column 14 is provided with a second guide cavity 44 and a second guide groove 45 which are interconnected. The second guide groove 45 is located in front of the circuit board 15. The second guide cavity 44 is connected to the heat dissipation shell 43 through adjacent metal pipes. The first guide groove 41 and the second guide groove 45 are both connected to the transparent shell 4. The cavities on the transparent shell 4 and the fixed column 14 are filled with inert gas. The inert gas is used to prevent the circuit board 15 and the LED lamp 151 from oxidizing and extend the service life of the circuit board 15 and the LED lamp 151. A power assembly is provided on the left side of the fixed column 14. The power assembly is used to drive the inert gas in the fixed column 14 to move.

[0040] Combination Figure 6 and Figure 7 As shown, the power assembly includes a dual-axis motor 46, the dual-axis motor 46 is fixedly connected to the left side of the fixed column 14, the first output shaft of the dual-axis motor 46 is fixedly connected to the first fan 47, the second output shaft of the dual-axis motor 46 is fixedly connected to the second fan 48, the first fan 47 is used to cool the heat dissipation shell 43 and the fixed column 14, the second output shaft of the dual-axis motor 46 is sealed and rotatably matched with the fixed column 14, the first fan 47 is located between the heat dissipation shell 43 and the fixed column 14, the second fan 48 is located in the second guide groove 45, and is used to drive the inert gas in the fixed column 14 to circulate.

[0041] Combination Figure 7-Figure 9As shown, a circumferentially distributed fixing plate 5 is fixedly connected to the heat dissipation shell 43, and a hole is provided in the middle of the heat dissipation shell 43 for ventilation, so that the wind driven by the first fan 47 flows near the heat dissipation shell 43. A first heat dissipation bar group 51 and a second heat dissipation bar group 52 are fixedly connected to the circuit board 15. The first heat dissipation bar group 51 is located on the front side of the circuit board 15, and the second heat dissipation bar group 52 is located on the rear side of the circuit board 15. The first heat dissipation bar group 51 and the second heat dissipation bar group 52 are both composed of a plurality of rectangular metal bars. The first heat dissipation bar group 51 and the second heat dissipation bar group 52 are both provided with symmetrically distributed The inclined plates are arranged on the first heat dissipation bar group 51 and the second heat dissipation bar group 52, and the inclined directions of the corresponding inclined plates are opposite. When the inert gas passes through the inclined plates on the first heat dissipation bar group 51 or the second heat dissipation bar group 52, the inert gas is guided toward the adjacent LED lamp 151 to accelerate the heat dissipation of the LED lamp 151. The transparent shell 4 is square, and the transparent shell 4 and the circuit board 15 form a U-shaped cavity. The first heat dissipation bar group 51 and the second heat dissipation bar group 52 are both located in the U-shaped cavity, so that the inert gas moves from the front side to the rear side of the circuit board 15 when passing through the transparent shell 4, thereby guiding the inert gas.

[0042] During the use of the LED lamp 151, the LED lamp 151 will emit a large amount of heat. When the LED lamp 151 is turned on, the dual-axis motor 46 is turned on synchronously. After the dual-axis motor 46 is turned on, the two shafts of the dual-axis motor 46 respectively drive the first fan 47 and the second fan 48 to rotate, and the first fan 47 and the second fan 48 rotate clockwise (from left to right), and the first fan 47 and the second fan 48 drive the wind to move to the right.

[0043] During the rotation of the second fan 48, the inert gas in the fixed column 14 moves. The inert gas first moves rightward from the second guide groove 45 and moves to between the front side of the circuit board 15 and the transparent shell 4. During the movement of the inert gas between the front side of the circuit board 15 and the transparent shell 4, the inert gas moves between the heat dissipation bars on the first heat dissipation bar group 51, and takes away the heat from the LED lamp 151 by contacting the heat dissipation bars, the circuit board 15 and the LED lamp 151. Then, the inert gas enters the first guide groove 41 through the rear side of the circuit board 15 and passes through the second heat dissipation bar group 51. The heat strip group 52, the inert gas entering the first guide groove 41 enters the annular cavity 24, and then enters the heat dissipation shell 43 through the metal tube on the rear side. The gas entering the heat dissipation shell 43 gathers toward the middle under the guidance of the fixing plate 5, and then diffuses forward. The fixing plate 5 makes the inert gas evenly distributed in the heat dissipation shell 43 to improve the heat dissipation efficiency. Then the gas on the front side of the heat dissipation shell 43 enters the second guide cavity 44 through the metal tube on the front side, forming a cycle, and the inert gas transfers heat to the first guide cavity 42, the heat dissipation shell 43 and the metal tube therebetween.

[0044] When the first fan 47 rotates, the first fan 47 rotates to guide the external wind, allowing the external wind to flow, and the external wind dissipates the heat to the first guide cavity 42, the heat dissipation shell 43 and the metal tube therebetween, thereby reducing the heat of the inert gas, and cooling the LED lamp 151 through the inert gas circulation to prevent the LED lamp 151 from overheating, thereby extending the service life of the LED lamp 151. After use, the staff turns off the dual-axis motor 46 and the LED lamp 151.

[0045] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
