[0024] Optionally, in the above-described light-blocking mechanism, the active door and the driven door are staggered along the axial direction of the light-emitting hole;

[0025] The second transmission member has a support plate on the side facing the active door, and the support plate creates a sliding gap between the second transmission member and the active door, within which a part of the driven door rotates.

[0029] A vehicle light includes a light-emitting unit and the aforementioned light-blocking mechanism, wherein the light-emitting unit is disposed on one side of the mounting assembly and is arranged opposite to the light-emitting hole.

[0030] A vehicle including the aforementioned headlights.

[0031] The light-blocking mechanism provided in this application includes a mounting assembly, movable doors, and a power assembly. The mounting assembly has a through-hole for supplying light to a light-emitting unit, which is positioned on one side of the mounting assembly. Two movable doors are rotatably mounted on one side of the mounting assembly, with their rotation planes perpendicular to the axis of the light-emitting hole for convenient arrangement and reduced space occupation. Specifically, when the movable doors are in the first position, they are positioned away from the light-emitting hole, allowing normal light emission.

[0050] The core of this application is to disclose a light-blocking mechanism to improve the safety performance of vehicle lights.

[0051] Another key aspect of this application is the disclosure of a vehicle lamp that includes the aforementioned light-blocking mechanism.

[0052] Another key aspect of this application is the disclosure of a vehicle that includes the aforementioned headlights.

[0053] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0054] Combination Figures 1-9 The light-blocking mechanism disclosed in this application includes a mounting assembly 100, a movable door 200, and a power assembly. The mounting assembly 100 has a through-hole 101 for supplying light to a light-emitting unit, which is mounted on one side of the mounting assembly 100. Two movable doors 200 are rotatably mounted on one side of the mounting assembly 100, with the rotation planes of the two movable doors 200 perpendicular to the axis of the light-emitting hole 101, facilitating arrangement and reducing space occupation. Specifically, when the movable door 200 is in the first position, it avoids the light-emitting hole 101, allowing normal light emission. When the movable door 200 is in the second position, it is positioned at the light-emitting hole 101, jointly blocking it, preventing normal light emission. The power assembly is mounted on the mounting assembly 100 and is connected to the movable door 200 for driving the movable door 200 to rotate between the first and second positions.

[0055] The mounting component 100 and the light-emitting unit can both be mounted on the lamp housing. The mounting component 100 and the light-emitting unit can be connected or not connected. It is only necessary to ensure that the position of the light-emitting part of the light-emitting unit corresponds to the position of the light-emitting hole 101 so that light can be emitted from the light-emitting hole 101.

[0056] The movable door 200 is rotatably mounted on the mounting assembly 100 by the drive of the power component. During the day or in bright sunlight, when the light-emitting unit of the vehicle headlights is not needed for illumination, the power component controls the movable door 200 to be in the second position, thus hiding the light-emitting unit and preventing external light from directly entering the lens position of the light-emitting unit through the light-emitting hole 101, avoiding light focusing and protecting the light-emitting unit and surrounding decorative parts. At night, when the light-emitting unit of the vehicle headlights is needed for illumination, the power component controls the movable door 200 to move from the second position to the first position, exposing the light-emitting hole 101, allowing light to shine out from the light-emitting hole 101 and achieving the illumination function.

[0057] Compared to existing technologies, the light-blocking mechanism disclosed in this application can achieve the effect of revealing or blocking the light-emitting hole 101 by rotating the movable door 200 on the mounting component 100. In non-lighting mode, blocking the light-emitting hole 101 reduces the risk of the light-emitting unit focusing light through the lens, thus improving the safety performance of the vehicle lights. At the same time, the rotation switching method of the movable door 200 can enhance the technological feel, sense of ceremony and fun of the vehicle lights.

[0058] The two movable doors 200 can be driven to rotate by different drive members 300. To simplify the structure and reduce costs, in some embodiments disclosed in this application, the two movable doors 200 are defined as an active door 210 and a driven door 220, respectively. The power assembly includes a drive member 300, a first transmission member 310, a second transmission member 320, and a third transmission member 330. The drive member 300 is mounted on the mounting assembly 100; the first transmission member 310 is mounted on the active door 210 and arranged on the same axis as the active door 210, and is drively connected to the drive member 300; the second transmission member 320 is mounted on the active door 210 and arranged on the same axis as the first transmission member 310; the third transmission member 330 is mounted on the driven door 220 and arranged on the same axis as the driven door 220, and engages with the second transmission member 320 for transmission. When the drive unit 300 is started, it can drive the first transmission unit 310 to rotate. The rotation of the first transmission unit 310 can drive the second transmission unit 320 and the active door 210 to rotate in the same direction. The rotation of the second transmission unit 320 can drive the third transmission unit 330 and the driven door 220 to rotate together, thereby realizing the joint drive of two active doors 200 by a single drive unit 300, reducing costs.

[0059] Depending on the actual situation, the drive component 300 can be a motor or other components, and is connected to the first transmission component 310 via gear transmission or other means. Specifically, the second transmission component 320 and the third transmission component 330 can directly mesh and transmit power. That is, during the rotation of the two movable doors 200, the second transmission component 320 and the third transmission component 330 rotate in opposite directions, driving the active door 210 and the driven door 220 to rotate towards the same side of the light emission hole 101 to achieve position switching. Alternatively, the second transmission component 320 and the third transmission component 330 can indirectly mesh and transmit power through a fourth transmission component such as gears. Along the axial direction of the light emission hole 101, the fourth transmission component avoids the position of the light emission hole 101 to avoid affecting the light emission of the light emission unit. In this embodiment, the second transmission component 320 and the third transmission component 330 rotate in the same direction, driving the active door 210 and the driven door 220 to rotate and switch to opposite sides of the light emission hole 101, producing different dynamic effects.

[0060] In some embodiments, the active door 210 and the driven door 220 are staggered along the axial direction of the light outlet 101; combined with Figure 12 A support plate 322 is provided on the side of the second transmission member 320 facing the active door 210. The support plate 322 creates a sliding gap between the second transmission member 320 and the active door 210, allowing a portion of the driven door 220 to rotate within the sliding gap. For example, the light-emitting hole 101 can be rectangular or other shapes, and the movable door 200 can be a rectangular plate structure or other shapes, as long as the movable door 200 can adequately block the light-emitting hole 101 at the second position.

[0061] It is understandable that, since the rotation angle corresponding to the rotation switching action of the movable door 200 between the first position and the second position is usually less than 360°, the first transmission member 310, the second transmission member 320 and the third transmission member 330 can be irregular gears corresponding to the rotation stroke of the movable door 200, rather than necessarily complete gears.

[0062] In some embodiments, combined with Figure 10 At least one of the first transmission component 310 and the second transmission component 320 is an integral structure with the active door 210, and is integrally molded by injection molding or other methods, which is convenient to produce and has low cost. Figure 11 The third transmission component 330 and the driven door 220 are integrated into one structure and are manufactured in one piece by injection molding and other methods, which is convenient to produce and has low cost.

[0063] When the active door 210 and the second transmission component 320 are separate structures, the combination Figure 10 and Figure 12The active door 210 is provided with a positioning post 211, and the second transmission component 320 is provided with a positioning hole 321. The positioning post 211 passes through the positioning hole 321, so that the positioning post 211 and the positioning hole 321 cooperate to achieve positioning and assembly of the two. The positions of the positioning post 211 and the positioning hole 321 can be interchanged without affecting their function, and the number includes, but is not limited to, the two shown in the figure.

[0064] To limit the rotation stroke of the movable door 200, in some embodiments, the mounting assembly 100 is provided with a first limiting part and a second limiting part. When the movable door 200 is in a first position, it abuts against the first limiting part; when the movable door 200 is in a second position, it abuts against the second limiting part. The first and second limiting parts can be block-shaped or columnar protrusions. In other embodiments, the mounting assembly 100 is provided with a guide post, and the movable door 200 is provided with a guide groove for the guide post to be inserted and slid. The rotation angle of the movable door 200 is limited by the limiting cooperation between the guide groove and the guide post. The structure of the guide groove can effectively reduce the weight of the structure and lower the cost.

[0065] The mounting assembly 100 serves as the mounting base for the movable door 200 and the power assembly. In some embodiments, the mounting assembly 100 includes a mounting base frame with multiple mounting posts. The movable door 200 and each transmission component are respectively mounted on the mounting posts and rotate around the mounting posts. The mounting posts can be integrally formed on the mounting base frame or set on the mounting base frame by means of adhesive bonding, screw connection, etc.

[0066] A specific operational process of the light-blocking mechanism disclosed in this application is as follows: A rotary motor is controlled by an electrical signal to rotate clockwise or counterclockwise. The rotary motor provides rotational power and can drive the first transmission component 310 to rotate. The first transmission component 310 drives the active door 210 and the second transmission component 320 to rotate in the same direction. The second transmission component 320 drives the third transmission component 330 and the driven door 220 to rotate synchronously in opposite directions. The visible state outside the vehicle headlight is achieved by the rotation of the active door 200 as the rotary motor rotates in both clockwise and counterclockwise directions, thus achieving the effect of blocking and displaying the light-emitting hole 101 on the mounting assembly 100. See also... Figure 1 , Figure 4 and Figure 7 It simulates an effect similar to the opening and closing of a door panel, and the changes in the shape of the headlights and / or the changes in the light-emitting area can be clearly observed from the outside of the headlights, which can effectively enhance the sense of ceremony and fun of the headlights.

[0067] The vehicle lamp disclosed in this application includes a light-emitting unit and the light-blocking mechanism described above. The light-emitting unit is disposed on one side of the mounting assembly 100 and is arranged opposite to the light-emitting hole 101 so that light is emitted from the light-emitting hole 101. Since it includes the light-blocking mechanism described above, it also has the aforementioned beneficial effects. Other structures refer to the prior art and will not be described in detail here.

[0068] The vehicle disclosed in this application includes a vehicle body and the aforementioned headlights. The headlights are mounted on the vehicle body. Since it includes the aforementioned headlights, it also includes the aforementioned structure and beneficial effects. Other structures refer to the prior art and will not be described in detail here.

[0069] Furthermore, the aforementioned headlights or light-blocking mechanisms can be reused and combined in various arrangements on vehicles, which will not be elaborated here.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
