DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1: As shown in Figures 1 to 10: A headlight with an angle adjustment function, comprising a light adjustment mechanism 1 and an inner cover 2, one side of the inner cover 2 is provided with an LED lamp holder 21, the light adjustment mechanism 1 comprises a headlight cover 10, the inner cavity of the headlight cover 10 is provided with a flat transparent plate assembly 12, the other side of the light adjustment mechanism 1 is provided with a magnetic protective cover 3, the inner side wall of the magnetic protective cover 3 is provided with an electromagnet seat 33, the outer side wall of the magnetic protective cover 3 is provided with a guide groove 30, the inner side of the guide groove 30 is slidably connected with a connecting arm 31, the magnetic protective cover 3 The outer wall of the headlight cover 10 is fixedly connected to a photosensor 32, the electromagnet seat 33 controls the position of the connecting arm 31 by magnetic attraction, the other end of the connecting arm 31 is connected to a linkage assembly 11, the linkage assembly 11 includes a telescopic plate 112, one end of the telescopic plate 112 is rotatably connected to a linkage plate 113, the other end of the telescopic plate 112 passes through the inner wall of the headlight cover 10 and is fixedly connected to the connecting arm 31, the other end of the linkage plate 113 is rotatably connected to a rotating seat 114, and the linkage plate 113 drives the flat transparent plate assembly 12 to rotate around the axis through the rotating seat 114.

In this embodiment, the headlight is installed at the front of the car, the inner cover 2 is embedded in the car, the light adjustment mechanism 1 is located outside the frame, and a circuit for controlling the headlight is arranged inside the inner cover 2. The light adjustment mechanism 1 is made of a material with good light transmittance. The LED lamp holder 21 is installed on the inner side wall of the light adjustment mechanism 1. There are multiple groups of LED lamp beads on the surface of the LED lamp holder 21, which can be used for switching between high and low beams of the car;

The magnetic protective cover 3 is arranged on the outer side of the light adjustment mechanism 1, and the photosensitive sensor 32 is arranged on the surface of the magnetic protective cover 3. Since the photosensitive sensor 32 is located at the outermost side of the front of the vehicle, when the light of the opposite lane shines over, it can capture the information of the opposite light in time and control the direction of the light in the light adjustment mechanism 1. The photosensitive sensor 32 controls the output current of the circuit board in the inner cover 2 and adjusts the current size passing through the electromagnet seat 33, thereby controlling the magnetic force size of the electromagnet seat 33, and utilizing the magnetic attraction force of the electromagnet seat 33 on the connecting arm 31 to The position of the connecting arm 31 is adjusted so that the connecting arm 31 translates inside the guide groove 30. The connecting arm 31 drives the telescopic plate 112 to be telescopically adjusted during the translation process, and the length of the telescopic plate 112 entering the headlight cover 10 is changed. When the telescopic plate 112 is continuously pushed inward, the linkage plate 113 is lifted up by the telescopic plate 112, and one end of the flat transparent plate assembly 12 is pried outward by the electric cylinder 13, so that the flat transparent plate assembly 12 rotates around the axis direction, thereby adjusting the incident angle between the light emitted from the LED lamp holder 21 and the flat transparent plate assembly 12;

In order to analyze the influence of the flat transparent plate assembly 12 on the direction and position of the light emitted from the LED lamp holder 21, in combination with the description of FIG. 9, the cone transparent plate 1 121 and the cone transparent plate 2 122 are a group of conical lenses arranged symmetrically at the center, and are made of transparent materials. The refractive index of light propagating in a vacuum is 1. Since the refractive index of light in an air environment is the smallest, which is close to the refractive index of light in a vacuum, the refractive index of the materials used in the flat transparent plate assembly 12 is greater than the refractive index of light in the air, which is 1. Therefore, when light is incident on the inside of the flat transparent plate assembly 12 at an inclined angle, the light is offset in the normal direction when propagating in the flat transparent plate assembly 12. When light is emitted from the inside of the flat transparent plate assembly 12 and propagates in the air, the direction of the light is offset in the direction of the normal. When the incident interface and the exit interface of the flat transparent plate assembly 12 are parallel, although the directions of propagation of the same beam of light in the air are still parallel after two refractions, the position of the exiting light is still offset compared to the initial position. From the outside, after refraction by the flat transparent plate assembly 12, the position of the LED lamp holder 21 is translated inward for a distance, so that the light in front of the front of the vehicle moves a distance to the middle, avoiding the light from being scattered in a larger range when meeting other vehicles and affecting the driving vision of oncoming vehicles.

Embodiment 2: As shown in Fig. 1, Fig. 4, Fig. 5 and Fig. 6, the flat transparent plate assembly 12 includes a cone transparent plate 121 and a cone transparent plate 122. The outer wall of the cone transparent plate 121 is fixedly connected with a rotating shaft 123, and the rotating seat 114 is fixedly connected with the cone transparent plate 121. The outer wall of the cone transparent plate 121 is slidably connected with the rotating shaft 123, and the cone transparent plate 121 is rotatably connected with the inner wall of the headlight cover 10 through the rotating shaft 123. The outer wall of the cone transparent plate 122 is rotatably connected with an electric cylinder 13, and the other end of the electric cylinder 13 is rotatably connected with the inner wall of the headlight cover 10. A locking assembly 14 is provided between the cone-transparent plate 1 121 and the cone-transparent plate 2 122 , and the locking assembly 14 includes two U-shaped seats 141 , and the two U-shaped seats 141 are respectively fixedly connected to the outer walls of the cone-transparent plate 1 121 and the cone-transparent plate 2 122 , and a tension spring 142 is fixedly connected between the two U-shaped seats 141 .

In this embodiment, when the light source is translated by adjusting the angle of the flat transparent plate assembly 12, the adjustment and correction range of the vehicle light is limited. Therefore, it is also necessary to converge the edge of the scattered light toward the center to change the direction of the outer scattered light. Combined with the description of Figure 9, in the optimized technical solution, the original two parallel flat transparent plate assembly 12 is replaced by two triangular cone transparent plates 121 and 122. When the cone transparent plates 121 and 122 are completely connected, the cone transparent plates 121 and 122 can form a two-sided parallel flat lens. When it is necessary to converge the scattered light on both sides, the cone transparent plate 122 is pulled from the outside to offset the cone transparent plate 122 from the cone transparent plate 121, so that the cone transparent plate 121 and the cone transparent plate 122 are separated from each other to form a staggered combination. The cone-transparent plate 1 121 and the cone-transparent plate 2 122 form a structure similar to a concave lens, that is, the shape of the combined cone-transparent plate 121 and the cone-transparent plate 2 122 changes from a flat plate to a concave plate. When the cone-transparent plate 1 121 and the cone-transparent plate 2 122 are tilted again, since the refraction interfaces on both sides are not parallel, when the light is emitted outward from the second interface, the direction of its normal is offset toward the inner wall, thereby completing the collection effect of the scattered light on the outside. In the middle position of the concave plate, the reflection interfaces formed by the cone-transparent plate 1 121 and the cone-transparent plate 2 122 are still parallel, so the middle light after the second refraction still converges in the middle of the road. After the innermost light is refracted for the second time, it is offset in a more inward direction, so that the light converges to the middle as a whole, avoiding the scattered light from interfering with the driving vision of oncoming vehicles.

Embodiment 3: As shown in Fig. 3, Fig. 4 and Fig. 5, a circuit board is arranged inside the inner cover 2, a connecting wire 20 is fixedly connected to the back of the inner cover 2, the electromagnet seat 33 and the electric cylinder 13 are both electrically connected to the circuit board, and the light sensor 32 is connected via the circuit board signal. The outer wall of the telescopic plate 112 is fixedly connected to a baffle 111, and the telescopic plate 112 is slidably engaged with the headlight cover 10.

In this embodiment, a circuit board is provided in the inner cover 2, and the circuit board supplies power to the electromagnet seat 33 and the electric cylinder 13 respectively, and adjusts the angle and staggered distance of the flat transparent plate assembly 12. The photosensitive sensor 32 can convert the collected light intensity signal into an electrical signal. After the photosensitive sensor 32 collects the light data of the oncoming vehicle, the electrical signal is transmitted to the circuit board to realize the regulation of the electromagnetic control module and the electric cylinder control module.

Embodiment 4: As shown in Figures 1 to 10, the present invention also uses a vehicle light angle adjustment system, including: a photosensitive module, a light adjustment module and an early warning module; the photosensitive module is used to detect the light of the oncoming vehicle's headlights, the light adjustment module is used to adjust the light angle of the vehicle's headlights, and the early warning module is used to remind the oncoming vehicle of the light management. The light adjustment module includes an electromagnetic control module and an electric cylinder control module; the electromagnetic control module is used to control the current intensity flowing into the electromagnet seat 33, and control the magnetic force of the electromagnet seat 33 on the connecting arm 31, so as to adjust the deflection angle of the flat transparent plate assembly 12, so as to achieve the effect of changing the light position; the electric cylinder control module is used to control the stroke of the electric cylinder 13, so as to adjust the traction position of the cone transparent plate 2 122, thereby changing the shape of the cone transparent plate 1 121 and the cone transparent plate 2 122, so as to achieve the effect of changing the light direction.

The working steps of the headlight angle adjustment system are as follows:

1) When the vehicle is driving, the light from the oncoming vehicle headlights converges into the lane, the photosensitive sensor 32 receives the oncoming light and controls the circuit board in the inner cover 2 to supply the operating voltage to the electromagnetic control module and the electric cylinder control module;

2) The electromagnetic control module adjusts the current flowing into the electromagnet seat 33, controls the magnetic attraction of the electromagnet seat 33 to the connecting arm 31, changes the position of the connecting arm 31, controls the length of the telescopic plate 112 inserted into the headlight cover 10, changes the deflection angle of the linkage plate 113, thereby lifting the flat transparent plate assembly 12 and adjusting the influence of the lens on the light position;

3) The electric cylinder control module adjusts the stroke of the electric cylinder 13 and controls the position of the second cone-transparent plate 122, changing the interlaced position between the first cone-transparent plate 121 and the second cone-transparent plate 122. The first cone-transparent plate 121 and the second cone-transparent plate 122 form lenses of different shapes. By changing the shape of the rear lens, the influence of the lens on the direction of light is adjusted;

4) Finally, the car's center console receives an early warning of the oncoming vehicle's light adjustment and controls the lights to switch, reminding oncoming vehicles to turn off their high beams.

In this embodiment, the headlight angle adjustment system mainly controls the magnetic force of the electromagnet seat 33 through the electromagnetic control module, and finally achieves the effect of controlling the overall deflection angle of the flat transparent plate assembly 12, and controls the stroke of the electric cylinder 13 through the electric cylinder control module. The output end of the electric cylinder 13 can drive the cone transparent plate 2 122 to separate from the cone transparent plate 1 121, so that the outer edges of the cone transparent plate 1 121 and the cone transparent plate 2 122 are staggered and separated, and the conical interface at the two edges is used to change the angle of the light after secondary refraction. The electromagnetic control module and the electric cylinder control module are both triggered by the photosensitive module, which is used to detect the oncoming headlights. During actual driving, it can also be independently controlled according to the road conditions. For example, when driving in multiple lanes, trucks generally drive in the slow lane, that is, on the far right side of the road, and cars generally drive in the fast lane, that is, on the far left side of the road; when driving in the slow lane, the truck has a greater need to observe the road on the left side and a smaller need to observe the road on the right side, so the light needs to be moved to the left. The headlight range can be adjusted through the center console, so that the light can be better concentrated on the required area.

Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
