Description

Technical Field

[0001] The present invention relates to the technical field of automotive headlights, and specifically, to a differential control system for mechanical movement and a headlight system. Background Art

[0002] Background Art: The development of the automotive industry has also driven the rapid progress of the headlight industry. The lighting forms of lamps are becoming more and more diverse, especially the bright and dark changes in the light-emitting area are becoming more and more popular. There are many disadvantages in the traditional design of directly controlling the brightness of the light source by chips. First, the principle is complex and the cost is high. Second, the manifestation form is single, and only full brightness or full darkness of the light-emitting area can be achieved. Third, if there are too many light-emitting areas to be controlled and the required chip power is too high, there will be problems of electronic failures and overheating. At the same time, the changes in the traditional light-emitting area mostly present in a two-dimensional style, with only changes in the plane visually, no three-dimensional sense, and no three-dimensional dynamic sense. Moreover, even if a mechanical mechanism is used to achieve a three-dimensional sense of solidity, the traditional implementation methods, such as using multiple motors to drive the movement of baffles, not only have a complex mechanism, numerous parts, high cost, and large space occupation, but also the complex transmission mechanism is unstable, resulting in large tolerances, and the achieved effect will have delays and inaccuracies.

[0065] The light-emitting areas are set to three, namely a first light-emitting area 51, a second light-emitting area 52, and a third light-emitting area 53. Corresponding to the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53: the baffles are set to three, namely a first baffle 21, a second baffle 22, and a third baffle 23; the guide rods are set to three, namely a first guide rod 210, a second guide rod 220, and a third guide rod 230; the guide grooves are set to three, namely a first guide groove 31, a second guide groove 32, and a third guide groove 33; the guide rails are set to three, namely a first guide rail 11, a second guide rail 12, and a third guide rail 13.

[0066] The first guide rail 11 includes a first section of the guide rail 111, a second section of the guide rail 112, and a third section of the guide rail 113 that are sequentially connected. The control panel 1 is arranged in a fan shape.

The second guide rail 12 includes a first section of the guide rail 121, a second section of the guide rail 122, and a third section of the guide rail 123 that are sequentially connected. The control panel 1 is arranged in a fan shape. The first section of the guide rail 121, the second section of the guide rail 122, and the third section of the guide rail 123 are all arranged in an arc shape. The first section of the guide rail 121 is concentric with the control panel 1, the second section of the guide rail 122 is eccentric with the control panel 1, and the third section of the guide rail 123 is concentric with the control panel 1. The third guide rail 13 includes a first section of the guide rail 131, a second section of the guide rail 132, and a third section of the guide rail 133 that are sequentially connected.

[0068] This embodiment also provides a vehicle lamp system, including the differential time difference control system for mechanical movement described above.

[0069] This embodiment adopts a method of connecting concentric guide rails and special-shaped guide rails in series to achieve differential movement or stillness of a single baffle, and adopts a method of connecting multiple guide rails in parallel to achieve differential movement or stillness of multiple baffles.

[0070] Example 2:

[0071] Those skilled in the art can understand this embodiment as a more specific illustration of Embodiment 1.

[0072] This embodiment provides a differential time difference control system, including a control disk, at least one baffle, at least one guiding groove, and a light-emitting area.

[0073] As Figure 1 shown, the position of the light-emitting area in the system remains fixed. The baffle covers the light-emitting area. The displacement of the baffle along the light-emitting area will change the exposed area of the light-emitting area, that is, the size of the light-emitting surface. A guiding rod is provided on the right side of the baffle. The guiding rod is clamped in the guiding groove and can only move along the guiding groove under the restriction of the guiding groove. Here, the position of the guiding groove also remains fixed. The first end of the guiding rod is fixedly connected to the baffle, and the second end of the guiding rod has a columnar structure. The columnar structure is inserted into the guiding rail on the control disk and can slide along the direction of the guiding groove relative to the control disk. The guiding rail is a special structure on the control disk. When the control disk rotates around the center of the control disk, the guiding rail rotates together with the control disk, thereby driving the columnar structure and the guiding rod to slide along the direction of the guiding groove, and further changing the shielding area of the baffle for the light-emitting area, so that part or all of the light-emitting area covered by the baffle is exposed.

[0074] The control disk is provided with a gear structure meshing with the motor gear structure. The gear structure of the control disk can drive the control disk to rotate counterclockwise or clockwise under the drive of the motor gear, and then drive the guiding rail to rotate counterclockwise or clockwise together. Since a part of the stroke of the guiding rail is not concentric with the control disk, when moving in this area, the side wall of the guiding rail will push the columnar structure at the second end of the guiding rod to move horizontally, and then drive the guiding rod and the baffle to move horizontally, improving the exposed area of the light-emitting area.

[0075] The following is an illustration in combination with the specific structure. As Figure 1 shown, the differential time difference control system of this embodiment includes a first baffle 21, a second baffle 22, a third baffle 23, a first light-emitting area 51, a second light-emitting area 52, and a third light-emitting area 53.

[0076] As Figure 1 shown, the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 are the lighting areas of the lamp, and their positions remain fixed. The first baffle 21, the second baffle 22, and the third baffle 23 are sequentially arranged in front of the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53, and respectively cover the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53, shielding the light-emitting area of the light-emitting area.

[0077] The differential time difference control system of this embodiment further includes a first guiding groove 31, a second guiding groove 32 and a third guiding groove 33. The first guiding groove 31 is clamped on both sides of the first guiding rod 210, and the first guiding groove 31 is slidably connected to the first guiding rod 210, so as to ensure that the first baffle 210 can only slide along the guiding groove. Similarly, the second guiding groove 32 is clamped on both sides of the second guiding rod 220, and the second guiding groove 32 is slidably connected to the second guiding rod 220, so as to ensure that the second baffle 220 can only slide along the guiding groove. The third guiding groove 33 is clamped on both sides of the third guiding rod 230, and the third guiding groove 33 is slidably connected to the third guiding rod 230, so as to ensure that the third baffle 23 can only slide along the guiding groove.

[0078] The control disk 1 in this embodiment is further provided with a control disk gear 14, and the motor 4 has a motor gear 41. When the motor 4 works, the control disk gear 14 is driven to rotate counterclockwise or clockwise through the transmission of the motor gear 41, so that the control disk 1 can rotate counterclockwise or clockwise around the control disk center 10.

[0079] The control disk 1 in this embodiment is provided with a first guide rail 11, a second guide rail 12 and a third guide rail 13. As Figure 2 shown, the first guide rail 11 is connected to the first guiding rod 210 through a columnar structure provided at the second end s1 of the first baffle 21. The columnar structure is inserted into the first guide rail 11. When the control disk 1 rotates, the columnar structure slides along the track of the first guide rail 11, converting the rotation of the control disk 1 into the movement of the columnar structure and the first guiding rod 210 along the direction of the guiding groove. Since the first baffle 21 covers the first light-emitting area 51, the light-emitting range of the first light-emitting area 51 can be changed by rotating the control disk 1. Similarly, the second baffle 22 covers the second light-emitting area 52, and a columnar structure at the second end s2 of the second baffle 22 is inserted into the second guide rail 12. When the control disk 1 rotates, the columnar structure can move in the second guide rail 12. The third baffle 23 covers the third light-emitting area 53, and a columnar structure at the second end s3 of the third baffle 23 is inserted into the third guide rail 13. When the control disk 1 rotates, the columnar structure can move in the third guide rail 13, thereby changing the light-emitting ranges of the second light-emitting area 52 and the third light-emitting area 53.

[0080] The first baffle 21, the second baffle 22, and the third baffle 23 complete their movements along the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 respectively under the traction of the first guide rod 210, the second guide rod 220, and the third guide rod 230. The first end f1 of the first guide rod 210 is fixedly connected to the first baffle 21, and the second end s1 is connected to the first guide rail 11 on the control disk and can slide relative to the first guide rail 11. The middle section of the first guide rod 210 is clamped in the first guide groove 31. Since the position of the first guide groove 31 is fixed, when the motor 4 of the control disk 1 is started, the control disk 1 rotates around the center 10 of the control disk, which can drive the first guide rod 210 and the first baffle 21 to slide along the direction of the first guide groove 31. Similarly, the first end f2 of the second guide rod 220 is fixedly connected to the second baffle 22, the second end s2 is connected to the second guide rail 12 on the control disk and can slide relative to the second guide rail 12. And the middle section of the second guide rod 220 is clamped in the second guide groove 32. Since the position of the second guide groove 32 is fixed, when the control disk 1 rotates around the center 10 of the control disk, it can drive the second guide rod 220 and the second baffle 22 to slide along the direction of the second guide groove 32. The first end f3 of the third guide rod 230 is fixedly connected to the third baffle 23, the second end s3 is connected to the third guide rail 13 on the control disk and can slide relative to the third guide rail 13. And the middle section of the third guide rod 230 is clamped in the first guide groove 31. Since the position of the third guide groove 33 is fixed, when the control disk 1 rotates around the center 10 of the control disk, it can drive the third guide rod 230 and the third baffle 23 to slide along the direction of the third guide groove 33.

[0081] The first guide rail 11, the second guide rail 12, and the third guide rail 13 also include different sections. As Figure 3 shown, the entire rotation angle stroke of the control disk 1 is divided into three sections, corresponding to the first rotation angle a1, the second rotation angle a2, and the third rotation angle a3 respectively.

[0082] The first guide rail 11 is divided into the first section of the first guide rail 111, the second section of the first guide rail 112, and the third section of the first guide rail 113. The first section of the first guide rail 111 and the second section of the first guide rail 112 are arcs, and their centers are the same as the center of the control disk, that is, the first section of the first guide rail 111 and the second section of the first guide rail 112 are concentric guide rails, that is, the distances from all points on the first section of the first guide rail 111 and the second section of the first guide rail 112 to the center of the control disk are the same. That is, during the rotation of the control disk, the first section of the first guide rail 111 and the second section of the first guide rail 112 slide past the columnar structure of the second end s1 of the first guide rod 210 without interference. As Figures 3 to 5As shown, when the control panel 1 rotates counterclockwise, during the travel of rotation angle section a1 and rotation angle section a2, since the columnar structure at the second end of the first guide rod 210 is always within the concentric track, its position will not change, and thus there is no displacement difference in the horizontal direction. Furthermore, the first baffle 21 remains stationary during the travel of rotation angle section a1 and rotation angle section a2. The first guide rail section 113 is a special-shaped guide rail, and the distances from the starting point and the ending point of the first guide rail section 113 to the center 10 of the control panel are different, and the distance from the ending point to the center 10 of the control panel is less than the distance from the starting point to the center 10 of the control panel. Therefore, during the travel of rotation angle section a3, a displacement difference is generated in the horizontal direction for the columnar structure at the second end s1 of the guide rod 210, and thus the first baffle 21 moves to the right during the travel of rotation angle section a3, and the first light-emitting area 51 is mechanically opened.

[0083] The second guide rail 12 is divided into a first section of the second guide rail 121, a second section of the second guide rail 122, and a third section of the second guide rail 123. The first section of the second guide rail 121 and the third section of the second guide rail 123 are arcs, and their centers are the same as the center of the control panel. Therefore, during the travel of rotation angle section a1 and rotation angle section a3, no displacement difference is generated in the horizontal direction for the columnar structure at the second end s2 of the second guide rod 220, and thus the second baffle 22 remains stationary during the travel of rotation angle section a1 and rotation angle section a3. The second section of the second guide rail 122 is a special-shaped guide rail, and the distances from the starting point and the ending point of the second section of the second guide rail 122 to the center 10 of the control panel are different, and the distance from the ending point to the center 10 of the control panel is less than the distance from the starting point to the center 10 of the control panel. Therefore, during the travel of rotation angle section a2, a displacement difference is generated in the horizontal direction for the columnar structure at the second end s2 of the second guide rod 220, and thus the second baffle 22 moves to the right during the travel of rotation angle section a2, and the second light-emitting area 52 is mechanically opened.

[0084] The third guide rail 13 is divided into a first section of the third guide rail 131, a second section of the third guide rail 132, and a third section of the third guide rail 133. The first section of the third guide rail 131 is a special-shaped guide rail. The distances from the starting point and the ending point of the first section of the third guide rail 131 to the center 10 of the control panel are different, and the distance from the ending point to the center 10 of the control panel is less than the distance from the starting point to the center 10 of the control panel. Thus, during the stroke of the third rotation angle a3, a displacement difference occurs in the columnar structure at the second end s1 of the first guide rod 210 in the horizontal direction, so that the first baffle 21 moves to the right during the stroke of the third rotation angle a3, and thus the first light-emitting area 51 is mechanically opened. The second section of the third guide rail 132 and the third section of the third guide rail 133 are arcs, and their centers are the same as the center of the control panel. Thus, during the strokes of the second rotation angle a2 and the third rotation angle a3, no displacement difference occurs in the columnar structure at the second end s3 of the third guide rod 230 in the horizontal direction, so that the third baffle 23 remains stationary during the strokes of the second rotation angle a2 and the third rotation angle a3. The number of the baffles and the light-emitting areas in the present invention is not limited to 3, and the control panel 1 can increase or decrease the number of guide rails, so as to control different numbers of baffles and light-emitting areas.

[0085] Further, the first guide rail 11, the second guide rail 12, and the third guide rail 13 can adjust the intersection positions of the concentric guide rails and the special-shaped guide rails on the first guide rail 11, the second guide rail 12, and the third guide rail 13 as needed, so as to adjust the starting time of the movement of different baffles, and thus realize the time difference of the opening of different light-emitting areas; they can also adjust the number and series connection order of the concentric guide rails and the special-shaped guide rails on the same guide rail as needed, so as to realize the intermittent movement of the baffle, and thus realize the intermittent opening and closing of the same light-emitting area.

[0086] Further, by adjusting the distance difference between the starting point and the ending point of the third section of the first guide rail 113 to the center 10 of the control panel, the displacement distance of the first baffle 21 in the horizontal direction can be adjusted. The greater the distance difference between the starting point and the ending point of the special-shaped guide rail to the center of the control panel, the greater the movement distance of the baffle, and the larger the exposed area of the light-emitting area; the smaller the distance difference between the starting point and the ending point of the special-shaped guide rail to the center of the control panel, the smaller the movement distance of the baffle, and the smaller the exposed area of the light-emitting area. Similarly, by adjusting the distance difference between the starting point and the ending point of the second section of the second guide rail 122 to the center 10 of the control panel, the displacement distance of the second baffle 22 in the horizontal direction can be adjusted; by adjusting the distance difference between the starting point and the ending point of the first section of the third guide rail 131 to the center 10 of the control panel, the displacement distance of the third baffle 23 in the horizontal direction can be adjusted.

[0087] Assume that the rotational angular velocity of the control panel 1 is uniform and unchanged. Then, the moving speed of the first baffle 21 is determined by the curvature of the special-shaped guide rail of the first three-section guide rail 113, and further by changing the curvature change of the first three-section guide rail 113, the moving speed of the first baffle 21 can be adjusted, and further the speed of change of the light-emitting area of the first light-emitting area 51 can be adjusted. Similarly, by changing the curvature change of the second two-section guide rail 122, the moving speed of the second baffle 22 can be adjusted, and further the speed of change of the light-emitting area of the second light-emitting area 52 can be adjusted; by changing the curvature change of the third one-section guide rail 131, the moving speed of the third baffle 23 can be adjusted, and further the speed of change of the light-emitting area of the third light-emitting area 53 can be adjusted. The greater the curvature of the special-shaped track, the faster the moving speed of the baffle, and the more obvious the change of the light-emitting area; the smaller the curvature of the special-shaped track, the slower the moving speed of the baffle, and the less obvious the change of the light-emitting area.

[0088] Furthermore, the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 can be arranged in an overlapping manner, and the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 can respectively have different characteristics, such as different forms of patterns or different light-emitting colors, and are superimposed to form different display effects; the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 can be non-overlapping and combined to form a complete display pattern.

[0089] According to the different arrangement methods of the first light-emitting area 51, the second light-emitting area 52, and the third light-emitting area 53 and the different positions of the second end s1 of the first guide rod, the second end s2 of the second guide rod, and the second end s3 of the third guide rod relative to the control panel 1, the lengths of the first guide rod 210, the second guide rod 220, and the third guide rod 230 can be adjusted adaptively.

[0090] Furthermore, when the control panel 1 rotates clockwise driven by the motor 4, the moving directions and moving distances of the first baffle 21, the second baffle 22, and the third baffle 23 are reversible. After counterclockwise movement and then clockwise movement, the light-emitting part moves to the right and then to the left, which can be flexibly selected according to requirements and has various effects. At the same time, including both, the overlapping effect and the two-way appearance effect cannot be achieved electronically.

[0091] Furthermore, the control panel is not limited to the illustrated sector shape, and the control panel can be designed as a circle. Similarly, the guide rail on the control panel can be designed to be closed at the head and tail, and thus the periodic movement of the baffle can be realized.

[0092] Furthermore, the rotation of the motor drives the rotation of the control disk, increasing the rotation speed of the motor, thereby increasing the rotation speed of the control disk, further increasing the rotation speed of the guide rail, further increasing the movement speed of the second end of the guide rod, further increasing the movement speed of the baffle, and further accelerating the opening speed of the light-emitting area. Similarly, decreasing the rotation speed of the motor will decrease the rotation speed of the control disk, further decreasing the rotation speed of the guide rail, further decreasing the movement speed of the second end of the guide rod, further decreasing the movement speed of the baffle, and further decreasing the opening speed of the light-emitting area. Thus, the display and closing rhythm of the light-emitting area can be adjusted according to requirements.

[0093] In traditional designs, the brightness and darkness of the light-emitting area are controlled by an electronic chip through a switch, and only instantaneous brightness or darkness can be achieved. The control program of the electronic chip is complex and costly. Moreover, traditional designs can only control the full brightness or full darkness of one light-emitting area and cannot change the area of the light-emitting area. Compared with traditional designs, the control in this embodiment is initiated by a motor, with a simple program and low cost. Moreover, combined with the mechanical movement of the baffle, the brightness and darkness combinations of multiple light-emitting areas can be achieved, and the size of the light-emitting area of a single light-emitting area can also be adjusted, making the light-emitting form more diverse. At the same time, by simply adjusting the rotation speed of the motor, the speed and time of the baffle movement can be precisely controlled to suit different light language modes.

[0094] By adopting the design method of connecting concentric guide rails and special-shaped guide rails in series, the present invention can achieve the differential movement of the baffle. This structure does not rely on an electronic chip, has a simple principle, low cost, and is easy to manage and control.
