DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0037] Example 1

[0038] In order to solve the above problems, the present invention provides a light shield, as shown in Figures 1 to 5, comprising:

[0039] Frame 1 is located in the path of the headlights;

[0040] A light blocking sheet 2 is provided on the frame 1;

[0041] The driving mechanism is connected to the light shielding plate 2 and is used to drive the light shielding plate 2 to move relative to the headlight to change the relative angle between the light shielding plate 2 and the light path.

[0042] The function of the light blocking sheet 2 is to block the light emitted by the headlights to concentrate the light and prevent it from diverging, thereby improving the lighting effect of the headlights.

[0043] The driving mechanism can drive the light blocking plate 2 to move to change the relative angle between the light blocking plate 2 and the light path, so that the light blocking plate 2 can block the light within a certain angle range and concentrate the light so that it is emitted at a specific angle, thereby avoiding the light from directly shining on the oncoming vehicles, thereby reducing the impact on the vision of the drivers on the oncoming vehicles to ensure driving safety.

[0044] The light shield, through the provision of the light shielding piece 2, can make the light emitted by the headlight more concentrated, thereby improving the lighting effect of the headlight; and is provided with a driving mechanism for driving the light shielding piece 2 to move, so as to change the relative angle between the light shielding piece 2 and the light path and concentrate the light so that the light is emitted at a specific angle, which can concentrate strong light and refract it on the road surface, thereby increasing the clarity of the road surface; and can prevent the light from directly shining on the oncoming vehicles, thereby reducing the impact on the vision of the drivers of the oncoming vehicles, thereby ensuring driving safety.

[0045] Preferably, as shown in Figure 1 , the light shielding plates 2 include multiple plates 2, which are evenly arranged on the frame 1 along its height. Each of the multiple plates 2 can control the light within a specific area of ​​the headlight. This arrangement allows for control of light emitted from various areas of the headlight, preventing unnecessary light blocking by the plates 2. This ensures that light concentration is maintained, thereby significantly improving light utilization.

[0046] In another more preferred embodiment, as shown in FIG2 , a light guide plate 3 is further provided on the frame 1 , and the light guide plate 3 and the light blocking plate 2 are perpendicular to each other, and the light guide plate 3 and the light path are parallel to each other.

[0047] It should be noted that the light guide 3 and light baffle 2 function similarly: they block the light emitted by the headlights to concentrate it and prevent it from diverging, thereby improving the lighting effect of the headlights. The light guide 3 and light baffle 2 work together to further concentrate the light emitted by the headlights. The difference is that the light guide 3 is always perpendicular to the light path of the headlights, while the light baffle 2 can be angled to the light path of the headlights, so that the light baffle 2 can emit the light at a specific angle.

[0048] In some preferred embodiments, as shown in FIG3 and FIG5 , the driving mechanism may include:

[0049] A driving motor 4, for providing driving force;

[0050] The reduction gear set 5 has one end connected to the driving motor 4 and the other end connected to the frame 1 or the light shielding plate 2 for driving the light shielding plate 2 to move.

[0051] The drive motor 4 provides driving force for driving the light shield 2. The reduction gear set 5 can reduce the rotation speed and increase the torque, which is beneficial for fine control of the movement of the light shield 2 and reduces the parameter requirements of the drive motor 4 to reduce costs.

[0052] In some more preferred embodiments, the light shield further includes a light sensing component for sensing light intensity, and the driving mechanism drives the light shield 2 to move in response to a sensing signal emitted by the light sensing component.

[0053] The light sensor assembly can be used to sense the intensity of light shining on the vehicle's headlights and thereby determine whether the vehicle is approaching a meeting vehicle. For example, when the light sensor assembly senses that the light intensity on the vehicle's headlights has reached a certain threshold, indicating that the vehicle is approaching a meeting vehicle, the drive mechanism then drives the light shield 2 to control the angle of the vehicle's light, preventing the light from directly shining on the approaching vehicle. This, in turn, reduces the impact on the driver's vision in the approaching vehicle, thereby ensuring driving safety.

[0054] In another more preferred embodiment, the light-blocking shield further comprises:

[0055] Image acquisition component, used to acquire image information;

[0056] a controller connected to the image acquisition component and capable of analyzing the image information and sending a control signal to the driving mechanism based on the analysis data;

[0057] The driving mechanism can drive the light blocking plate 2 to move in response to a control signal sent by the controller.

[0058] This image acquisition component can be used to capture images in front of the vehicle and transmit the image information to the controller. The controller analyzes the image information to determine whether the vehicle is approaching a meeting vehicle and sends a control signal to the drive mechanism based on the analyzed data. For example, the controller analyzes the image information and concludes that the vehicle is approaching a meeting vehicle, and sends a control signal to the drive mechanism. The drive mechanism then drives the light shield 2 based on the control signal to control the angle of the headlights, preventing the headlights from directly shining on the approaching vehicle, thereby reducing the impact on the driver's vision in the approaching vehicle and ensuring driving safety.

[0059] In some preferred embodiments, the surface of the light shield 2 may be provided with a mirror layer for refracting light. This mirror layer can refract the light incident on the light shield 2, so that the light shield 2 can not only focus the light from the headlights, but also refract the blocked light onto the ground at a certain angle through the mirror layer, thereby improving the lighting effect and light utilization rate.

[0060] Example 2

[0061] The embodiment is a further improvement based on the first embodiment, and the improvement is that, as shown in FIG. 1 and FIG. 2 , the driving mechanism is connected to the light-blocking plate 2 and can drive the light-blocking plate 2 to move relative to the frame 1 .

[0062] In this embodiment, the driving mechanism is connected to the light shielding plate 2 and can drive the light shielding plate 2 to move relative to the frame 1 to change the relative angle between the light shielding plate 2 and the light path, thereby achieving control of the light irradiation direction.

[0063] In some embodiments, as shown in FIG1 and FIG2 ,

[0064] The frame 1 includes a body and a shaft 6 provided on the body, wherein the shaft 6 is perpendicular to the light path, and the light shielding sheet 2 is connected to the body of the frame 1 via the shaft 6;

[0065] The driving mechanism is connected to the rotating shaft 6 and can drive the rotating shaft 6 to rotate so as to drive the light blocking plate 2 to rotate.

[0066] Specifically, the rotating shaft 6 may include two rotating shafts 6 coaxially disposed on either side of the light shielding sheet 2, one end of each rotating shaft 6 being connected to the light shielding sheet 2 and the other end being rotatably connected to the frame 1. Alternatively, the rotating shaft 6 may include only one rotating shaft 6, with both rotating ends being rotatably connected to opposite sides of the frame 1, and the light shielding sheet 2 being disposed on the rotating shaft 6.

[0067] The driving mechanism can drive the rotating shaft 6 to rotate, thereby driving the light blocking plate 2 to rotate, so as to change the relative angle between the light blocking plate 2 and the light path, thereby controlling the light irradiation direction.

[0068] In some embodiments, the driving mechanism may include multiple ones, each of which corresponds to one light shielding sheet 2. In this way, the multiple light shielding sheets 2 can be independently controlled.

[0069] In some embodiments, a single driving mechanism may be provided to synchronously control multiple light shielding plates 2. Specifically, as shown in FIG3 , a driven wheel 7 is provided on the rotating shaft 6, and the driven wheels 7 on two adjacent rotating shafts 6 are connected to each other;

[0070] A driving wheel 8 is connected to the output shaft of the driving mechanism. The driving wheel 8 is connected to any one or more of the driven wheels 7 and can drive the driven wheels 7 to rotate.

[0071] In some other embodiments, the driven wheels 7 or the driven wheel 7 and the driving wheel 8 can be connected by a chain or a belt.

[0072] In some embodiments, as shown in FIG2 , a light guide plate 3 is further provided on the frame 1 . In order to prevent the light guide plate 3 from affecting the movement of the light blocking plate 2 , the light blocking plate 2 is provided with a clearance groove 9 at a position corresponding to the light guide plate 3 .

[0073] Example 3

[0074] This embodiment is a further improvement based on the first embodiment, and the improvement is that: as shown in Figures 4 and 5, the frame 1 is movably arranged on the vehicle body, the driving mechanism is connected to the light-blocking plate 2 through the frame 1, and can drive the frame 1 to move, thereby driving the light-blocking plate 2 arranged on the frame 1 to move.

[0075] In this embodiment, the driving mechanism can drive the frame 1 to move, thereby driving the light shielding plate 2 provided on the frame 1 to move, so that the light shielding plate 2 can block the light within a certain angle range and concentrate the light so that it is emitted at a specific angle, thereby preventing the light from directly shining on the oncoming vehicles, thereby reducing the impact on the sight of the drivers on the oncoming vehicles, and ensuring driving safety. And when the driving mechanism drives the frame 1 to move and drives the light shielding plate 2 to move, the path of the light can be deflected. For example, the angle formed between the light shielding plate 2 and the diameter of the light is 45°. In the initial state, as shown in Figure 5, the light shielding plate 2 can deflect the light so that it can be emitted toward the ground at an angle of 45 degrees. When the driving mechanism drives the frame 1 to rotate 90 degrees, at this time, as shown in Figure 4, the light can be deflected 45 degrees and emitted toward the left or right side of the vehicle.

[0076] In one embodiment, as shown in FIG4 and FIG5 , the frame 1 includes a first frame 11 and a second frame 12 rotatably disposed on the first frame 11 , and the light shielding sheet 2 is disposed on the second frame 12 ;

[0077] The driving mechanism is connected to the second frame 12 and can drive the second frame 12 to rotate, thereby driving the light blocking sheet 2 to move.

[0078] Among them, the first frame 11 serves as the main frame 1 of the light-blocking shield, is fixed to the vehicle body, and can provide a mounting base for the second frame 12 and determine the rotation axis for the rotation of the second frame 12, so that the second frame 12 can rotate relative to the rotation axis determined by it.

[0079] Specifically, as shown in FIG5 , the second frame 12 may be provided with a gear ring 13, and the drive mechanism may be provided with a worm 14 that cooperates with the gear ring 13. The drive mechanism drives the worm 14 to rotate, and the cooperation between the worm 14 and the gear ring 13 drives the second frame 12 to rotate relative to the first frame 11, thereby driving the light barrier provided on the second frame 12 to move.

[0080] Alternatively, the second frame 12 may be provided with a gear ring 13, and the driving mechanism may be provided with a gear that cooperates with the gear ring 13. The driving mechanism drives the gear to rotate, and the cooperation between the gear and the gear ring 13 drives the second frame 12 to rotate relative to the first frame 11, thereby driving the light barrier provided on the second frame 12 to move.

[0081] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
