In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] The light shield movement mechanism according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 12 As shown, the sunshade movement mechanism according to an embodiment of the present invention includes: a base 8, a power mechanism, a transmission mechanism and a sunshade 1. The power mechanism is arranged on the base 8, and the power mechanism can perform circumferential rotational motion; the transmission mechanism is arranged on the base 8, and the transmission mechanism is connected to the power mechanism, and the transmission mechanism can reciprocate in a straight line direction under the drive of the power mechanism; the sunshade 1 is rotatably arranged on the base 8, and the connecting rod 11 of the sunshade 1 is connected to the transmission mechanism. When the power mechanism rotates in the circumferential direction, it drives the sunshade 1 to move through the transmission mechanism, so that the sunshade sheet 12 of the sunshade 1 opens and closes.

[0039] According to one embodiment of the present invention, the power mechanism includes a turntable 6 and a motor 9. The turntable 6 is rotatably mounted on the base 8. The outer peripheral surface of the turntable 9 has teeth 61. The motor 9 is fixed to the base 8. A gear is fixed to the output shaft of the motor 9. The gear meshes with the teeth 61. The motor 9 drives the turntable 6 to rotate. Figure 1 and Figure 4 It can be seen that an arc segment on the outer circumference of the turntable 9 has teeth 61, and the motor 9 drives the turntable 6 to perform reciprocating rotation within the length range of the teeth 61. Figure 11 It can be seen that a pressure plate 5 is provided on the turntable 6 , and the turntable 6 rotates between the base 8 and the pressure plate 5 . The pressure plate 5 can protect the turntable 6 from rotating and at the same time can limit the turntable 6 from separating from the base 8 .

[0040] Furthermore, the base 8 has a guide portion, and the transmission mechanism includes a slider 2, which is slidably connected to the guide portion. The guide portion includes two oppositely arranged guide grooves 81. One side of the slider 2 slides in one guide groove 81, and the other side of the slider 2 slides in the other guide groove 81. The sliding direction of the slider 2 is perpendicular to the plane of the turntable 9. In other words, the two guide grooves 81 are used to guide the slider 2 so that the slider 2 can only move along the guide grooves 81. The guide grooves 81 are arranged perpendicular to the plane of the turntable 9, so that the movement direction of the slider 2 is perpendicular to the rotation plane of the turntable 9.

[0041] Furthermore, a guide hole 62 is formed on the turntable 6, and the guide post 21 of the slider 2 is located in the guide hole 62. The guide direction of the guide hole 62 is not orthogonal and parallel to the sliding direction of the slider 2. When the turntable 6 rotates, the guide post 21 of the slider 2 moves in the guide hole 62 to drive the slider 2 to reciprocate along the sliding direction. In other words, the guide hole 62 is a waist-shaped hole, and the length direction of the guide hole 62 intersects the plane of the turntable 6 at an acute angle, so that Figure 11 It can be seen that the guide post 21 of the slider 2 passes through the guide hole 62. Since the slider 2 is confined in the guide groove 81, when the turntable 6 rotates, the slider 2 moves in the guide hole 62 and is guided in the guide groove 81 at the same time.

[0042] According to one embodiment of the present invention, a support portion is provided on the base 8, comprising two opposing mounting plates 82. One connecting rod 11 of the sunshade 1 is rotatably connected to one mounting plate 82 via a latch 7, while the other connecting rod 11 of the sunshade 1 is rotatably connected to the other mounting plate 82 via another latch 7. Preferably, the centerline of one latch 7 is collinear with the centerline of the other latch 7, and the rotation axis of the turntable 6 is orthogonal to the centerline of the latches 7.

[0043] Combine Figure 3 、 Figure 5 、 Figure 6 and Figure 10 The latch 7 is made of plastic, the interior of the latch 7 is hollow, and the two end sizes of the latch 7 are larger than the middle size. When the latch 7 connects the mounting plate 82 and the light shield 1, the latch 7 deforms inward and then resets. The two ends of the latch 7 can prevent the mounting plate 82 and the light shield 1 from separating. In addition, the two mounting plates 81 support and install one light shield 1, and the center lines of the two latches 7 are collinear, which ensures that the two rotation axes corresponding to the two ends of the light shield 1 are collinear, so that the light shield 1 can be more stable and reliable when it moves.

[0044] In this embodiment, there are three sunshades 1, which are rotationally symmetrically arranged about the rotation axis of the turntable 6. When opening and closing, the light shielding plates 12 of the sunshades 1 move closer to or farther from the rotation axis of the turntable 6. The three light shielding plates 12 are joined together to form a hemispherical structure, which can effectively block sunlight and prevent it from burning the headlights after being focused by the lens 3.

[0045] According to one embodiment of the present invention, there are three supporting portions, each corresponding to one of the three light shields 1. The light shield 1 has two connecting rods 11, symmetrically arranged on either side of a light shielding sheet 12. One connecting rod 11 is rotatably connected to a corresponding mounting plate 82 via a latch 7, and the other connecting rod 11 is rotatably connected to another corresponding mounting plate 82 via another latch 7. Since each connecting rod 11 requires one mounting plate 82 for installation, the number of mounting plates 82 and the number of connecting rods 11 are both six. The connecting rod 22 of the slider 2 is inserted into the connecting rod 11, and a certain gap is left between the outer circumference of the connecting rod 22 and the connecting rod 11. This gap provides space for the rotational movement of the connecting rod 11, thereby preventing interference with the linear movement of the connecting rod 22.

[0046] On this basis, there are three guide holes 62 and three sliders 2. The three sliders 2 correspond one to one with the three guide holes 62. One light shield 1 corresponds to two sliders 2. One connecting rod 11 is connected to one slider 2, and another connecting rod 11 is connected to another slider 2. In other words, one slider 2 in the present invention has two connecting rods 22, and the two connecting rods 22 respectively drive the two light shields 1 to move. The slider 2 can act on the two light shields 1 at the same time, and the two connecting rods 11 on the light shield 1 are subjected to force at the same time. This can make the light shield 1 more stable when rotating and prevent the light shield 1 from twisting. Figure 6 、 Figure 7 and Figure 8 It can be seen that the connecting rod 11 includes a rotating bar and a connecting bar, which form a V-shaped structure. The rotating bar is rotatably connected to the mounting plate 82, and at the same time, the end of the rotating bar away from the connecting bar is movably connected to the connecting rod 22 on the slider 2. The connecting rod 11 is designed in this way, and the lever principle is utilized, so that the slider 2 only needs to move a small distance to drive the light shield 1 to complete the movement from the light output surface of the lens 3 to the side of the lens 3.

[0047] The present invention further discloses a vehicle lamp comprising the aforementioned light shield movement mechanism, a lens 3, and a lens holder 4. The lens 3 is mounted on a base 8 via the lens holder 4. The lens 3 is positioned on the rotation axis of a turntable 6. The light shield 1 moves between above and to the side of the lens 3. In other words, when the light shield 1 of the present invention is opened, it flips from the inside out, while the lens 3 is positioned within the turntable 6. When shielding light, the light shield 1 can completely cover the lens 3. When the vehicle lamp is in operation, the light shield 1 flips outward to the side of the lens 1 without affecting the operation of the lens 1.

[0048] The beneficial effect of the present invention is that the present invention utilizes a power mechanism to provide circumferential rotational power, utilizes the slider 2 and the guide hole 62 for guidance, converts the circumferential rotational motion into linear motion, and then converts the linear motion into the rotational motion of the light shield 1 through the connecting rod 11 on the light shield 1, so that the light shield 1 can perform a shading action and can move in the narrow space inside the car light, making the entire structure simple and compact, and the dynamic opening and closing effect of the light shield meets the personalized lighting needs of consumers. At the same time, the light shield can effectively block the external sunlight from focusing, avoiding the failure of the car light after being exposed to sunlight for a long time, thereby protecting the car light and increasing the service life of the car light.
