[0067] Another core of the utility model is to disclose a vehicle lamp, which comprises the above-mentioned shading component.

[0068] Another core of the utility model is to disclose a vehicle, which comprises the above-mentioned vehicle lamp.

[0069] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0070] Combination Figure 1-Figure 25 The shading assembly disclosed in the embodiment of the utility model includes a frame assembly 100, a shading sheet 200 and a power assembly 300. The frame assembly 100 serves as an installation base. The shading sheet 200 and the power assembly 300 are both arranged on the frame assembly 100, and the frame assembly 100 is provided with a light outlet hole for light emitting unit 400 to emit light. The shading sheet 200 is a plurality of rotatably arranged on the frame assembly 100, and is arranged around the light outlet hole. When the shading sheet 200 rotates to a first limit position, each shading sheet 200 is assembled with each other and blocks the light outlet hole. When the shading sheet 200 rotates to a second limit position, each shading sheet 200 avoids the light outlet hole. The power assembly 300 is transmission-connected with the shading sheet 200, and is used to drive the shading sheet 200 to rotate between the first limit position and the second limit position. By changing the position of the shading sheet 200 relative to the light outlet hole, the light outlet hole can be exposed and blocked, and the light emitting unit 400 can be exposed and hidden accordingly.

[0071] Among them, the frame assembly 100 and the light-emitting unit 400 can both be set on the lamp housing 500, and the frame assembly 100 and the light-emitting unit 400 can be connected or not connected. It only needs to ensure that the light-emitting part of the light-emitting unit 400 corresponds to the position of the light-emitting hole so that light can be emitted from the light-emitting hole.

[0072] The shading sheet 200 is rotatably disposed on the frame assembly 100 by the drive of the power assembly 300, and the shading sheet 200 is driven by the power assembly 300 to switch between the first limit position and the second limit position, so as to achieve the shading assembly to block and avoid the light-emitting unit 400. Specifically, when the shading sheet 200 rotates from the second limit position to the first limit position, each shading sheet 200 rotates in a direction close to each other, and when the shading sheet 200 rotates from the first limit position to the second limit position, each shading sheet 200 rotates in a direction away from each other.

[0073] When the light-emitting unit 400 is used for lighting without the use of car lights during the day or under strong sunlight, the power component 300 controls the shading sheet 200 to be in the first extreme position, and the shading sheets 200 are attached to each other and together block the light-emitting unit 400, so that the light from the outside cannot be incident on the lens position of the light-emitting unit 400, thereby preventing sunlight from shining on the lens and forming a focus, thereby protecting the light-emitting unit 400 and surrounding decorative parts and other structures; when the light-emitting unit 400 is used for lighting at night and when the car lights are needed, the power component 300 controls the shading sheet 200 to be changed from the first extreme position to the second extreme position, so that the light outlet hole is exposed, and light can be emitted from the light outlet hole to achieve the lighting function.

[0074] Compared with the prior art, the shading assembly disclosed in the embodiment of the utility model can achieve the effect of revealing and blocking the light output hole through the rotational movement of each shading sheet 200 on the frame assembly 100. In the non-lighting mode, the blocking of the light output hole reduces the risk of the light-emitting unit 400 focusing light through the lens, thereby improving the safety performance of the car lamp. At the same time, the rotational switching method of the shading sheet 200 can enhance the sense of technology, ritual and fun of the car lamp.

[0075] Furthermore, the rotation axis of each shading sheet 200 is perpendicular to the axis of the light exit hole, and the rotation axis of each shading sheet 200 is on the same plane, so that the rotation switching of each shading sheet 200 between the first extreme position and the second extreme position can simulate an effect similar to the opening and closing of petals.

[0076] The number of the shading sheets 200 can be two, three, four or more. Each shading sheet 200 can be set as a flat structure or a curved structure. When each shading sheet 200 is set as a curved structure, when each shading sheet 200 is in the first extreme position, it can be assembled to form a similar Figure 5, Fig.18 and Fig. 22 The utility model does not limit the shape of each shading sheet 200, as long as the shading sheet 200 can cover the light-emitting unit 400 when it is in the first extreme position.

[0077] The position switching of each shading sheet 200 between the first extreme position and the second extreme position can be driven by different power components 300 respectively. In order to simplify the structure and ensure the synchronization of the rotation movement of each shading sheet 200, each shading sheet 200 is preferably driven by the same power component 300.

[0078] In a specific embodiment disclosed in the present utility model, the power component 300 includes an opening and closing bracket 330, a rotating disk 320 and a driving member 310.

A planar spiral rack 322 that meshes with the opening and closing gear 331 is provided on one side end face of the rotating disk 320. The planar spiral rack 322 is arranged around the avoidance hole 321. When the rotating disk 320 rotates, the planar spiral rack 322 rotates accordingly and can drive each opening and closing gear 331 to rotate.

[0080] In this embodiment, the plane spiral rack 322 on the rotating disk 320 can convert the plane rotational motion of the rotating disk 320 into the rotational motion of the opening and closing gear 331 in a direction perpendicular to the plane of the rotating disk 320, that is, the rotation axes of the rotating disk 320 and the opening and closing gear 331 are perpendicular to each other. Fig.11 It can be understood that the plane spiral rack 322 in this embodiment is equivalent to deforming the rack on the bevel gear into a plane structure on the rotating disk 320, and adjusting certain parameters so that it can play the role of the bevel gear in changing the transmission direction. In order to avoid the meshing between the opening and closing gear 331 and the plane spiral rack 322 from being disengaged from each other, it is set that during the rotation of the light shielding sheet 200, the meshing position of the opening and closing gear 331 and the plane spiral rack 322 always avoids the end position of each plane spiral rack 322.
