Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The following is for reference. Figures 1-10The opening and closing mechanism 100 of the lamp according to the first aspect of the present invention is described.

[0036] like Figure 1 As shown, the opening and closing mechanism 100 of the lamp according to an embodiment of the present invention has no limited application field. For example, it can be used in vehicles, including but not limited to interior and exterior lamps of various vehicles such as automobiles and trains; at the same time, it can also be extended to indoor and outdoor lighting, industrial lighting, landscape lighting, advertising displays, stage lighting, and other occasions with lamps. For the sake of simplicity, the following description will take the application of the opening and closing mechanism 100 in a vehicle as an example. The application of the opening and closing mechanism 100 in other devices will not be described in detail.

[0037] like Figure 1 As shown, the opening and closing mechanism 100 of the lamp includes: a cover plate 10, a blade assembly 30, and a transmission assembly 40. The cover plate 10 is provided with a window 11 corresponding to the light-emitting unit of the lamp.

[0038] At this time, the window 11 on the cover plate 10 directly corresponds to the light-emitting unit of the lamp and is the channel for light to be emitted.

[0039] The blade assembly 30 is used to control the light-transmitting area of ​​the window 11, thereby achieving light regulation.

[0040] Optionally, the luminaire also includes a lens, and the light-emitting unit is a high and low beam module. Therefore, in sunlight, the blade assembly 30 can be completely closed to prevent sunlight from directly passing through the lens and shining into the interior of the luminaire, thereby causing ablation or thermal damage to the internal components. At night or in dark environments, the blade assembly 30 can open appropriate openings to allow the high and low beam modules to illuminate the outside, ensuring optimal lighting performance.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the blade assembly 30 includes at least two blades 32. The blade assembly 30 has a maximum position and a minimum position. In the maximum position, all blades 32 are arranged circumferentially along the window 11 and enclose to form the maximum opening 321.

[0042] As can be seen, all the leaves 32 together form an area that allows maximum light to pass through, thereby maximizing the lighting effect.

[0043] In some alternative embodiments, when the maximum opening 321 is reached, the multiple blades 32 may be connected sequentially or spaced apart, but they are still arranged circumferentially.

[0044] In some technical solutions, when the blade assembly 30 is in the maximum opening 321, multiple blades 32 are closely connected. This seamless arrangement avoids unnecessary light leakage and ensures that light can pass through the designated maximum opening 321 area evenly and in a concentrated manner.

[0045] Alternatively, in some other technical solutions, when the blade assembly 30 is at its maximum opening 321, the multiple blades 32 are spaced apart. This arrangement can create specific lighting effects because the spaced-apart blades 32 can produce unique light and shadow effects, increasing the diversity of the environmental atmosphere.

[0046] In some such Figures 2-3 In the specific embodiment shown, the blade assembly 30 includes six blades 32.

[0047] Reference Figures 2-8 When in the minimum position, all blades 32 are arranged circumferentially along the window 11 to completely cover the window 11 or enclose it to form the minimum opening 321. The maximum opening 321 and the minimum opening 321 are set corresponding to the window 11, and the area of ​​the minimum opening 321 is smaller than that of the maximum opening 321.

[0048] When the blade assembly 30 is in its minimum position, all blades 32 are arranged circumferentially along the window 11, which can achieve two main states: completely covering the window 11 or enclosing it to form a minimum opening 321 with a certain light-transmitting area.

[0049] In some technical solutions, such as Figure 2 , Figure 7 and Figure 8 As shown, when the window 11 is completely covered, the blades 32 are tightly joined together without any gaps, ensuring that the window 11 is completely blocked, thereby achieving the purpose of completely blocking the light from passing through.

[0050] In some other technical solutions, such as Figure 3 As shown, the design of the minimum opening 321 allows a certain amount of light to pass through, which is achieved by adjusting the position of the blade 32 to form a small light-transmitting hole. At this time, the area of ​​this small opening 321 is smaller than the area of ​​the maximum opening 321.

[0051] Combination Figure 1 The transmission component 40 is connected to all the blades 32 of the blade assembly 30 to drive the blade assembly 30 to switch between the maximum and minimum positions, thereby adjusting the area of ​​the opening 321 enclosed by all the blades 32.

[0052] The transmission assembly 40 is used to convert the operating force into the actual movement of the blade 32, thereby achieving precise control over the opening and closing of the blade assembly 30.

[0053] Optionally, the transmission component 40 includes, but is not limited to, gears, connecting rods, and slides.

[0054] Alternatively, the source of the operating force is highly flexible, and can be achieved through manual drive or motor drive. Manual drive can be a simple knob or lever, allowing the user to control the position of the blade 32 with physical force; this method is simple and intuitive. Motor drive, on the other hand, helps to achieve a more automated and intelligent effect. For example, the precise adjustment of the blade 32 position can be achieved through a controller.

[0055] In summary, the opening and closing mechanism according to this embodiment of the utility model effectively blocks and adjusts the light-emitting unit of the lamp by setting a blade assembly. By setting windows on the cover plate corresponding to the light-emitting unit of the lamp, it ensures that light can be transmitted as needed. By setting a transmission assembly connected to all blades, the blade assembly is driven to switch between different positions, achieving dynamic adjustment of the opening area. This design not only effectively reduces focusing phenomena caused by direct light but also flexibly adapts to different lighting conditions, protecting surrounding components from high-temperature damage.

[0056] In some specific embodiments, such as Figure 5 and Figure 8 As shown, during the entire process of the blade assembly 30 switching between the maximum and minimum positions, all blades 32 are sequentially spliced ​​along the circumference of the window 11 to form a closed loop opening 321.

[0057] This configuration ensures that the arrangement of the blades 32 is tight and orderly, whether the opening is at its maximum or minimum, thus guaranteeing precise control over the light-transmitting area.

[0058] Furthermore, in some optional embodiments, to achieve a more flexible adjustment effect, the multiple blades 32 move radially during switching. When the blade assembly 30 is in the open state, the tips of the multiple blades 32 are located on the same circumference, which is the boundary of the opening 321 formed by the combined tips of the multiple blades 32. This arrangement ensures the regularity of the shape of the opening 321 and the consistency of the edges of the opening 321.

[0059] It is worth noting that the shape of the blade 32 is not limited in the opening and closing structure of this utility model. Furthermore, the blade 32 can be constructed in various shapes, such as straight lines, arcs, serrations, or any other geometric shape. Due to the diversity of the blade 32's shape, by adjusting the position of the blade 32, openings 321 of different shapes and sizes can be created, thereby achieving flexible control over the light-transmitting area. In addition, due to the diversity of the blade 32's shape, even when the tips of all blades 32 are located on the same circumference, the actual shape of the formed opening 321 can be circular, elliptical, polygonal, or other more complex geometric patterns. Here, the shape of the blade 32 can be adjusted according to personal preference or specific functional requirements, thereby improving the flexibility of the lamp's use; this application does not impose specific limitations on the shape of the blade 32.

[0060] According to some optional embodiments of the present invention, each blade 32 has a first side and a second side, and the included angle between the first side and the second side is the central angle. The central angles of all blades 32 are equal.

[0061] Specifically, when the center angles of all blades 32 are equal, the blade assembly 30 is in the state of maximum opening 321 or minimum opening 321, and the blades 32 can be evenly distributed and form a complete closed-loop structure. This uniform distribution ensures that the boundaries of the light-transmitting openings 321 are symmetrical, avoiding gaps or overlaps caused by inconsistent blade angles, thereby improving the overall visual effect and lighting quality of the lamp.

[0062] From a functional perspective, the uniformity of the leaf center angle also ensures the uniformity of light transmittance. When the leaves 32 close together to form the opening 321, the shading range of each leaf 32 is balanced, thus avoiding localized overly bright or dark areas.

[0063] When the blade assembly 30 is in its minimum position, the intersection of the first and second sides of all blades 32 is located at the center of the window 11. This means that when all blades 32 are joined together, they can completely cover the window 11 without gaps, achieving a thorough light-blocking effect. It also reduces visual disharmony caused by misalignment or uneven spacing of the blades 32.

[0064] Reference Figure 5 Throughout the entire process of the blade assembly 30 switching between the maximum and minimum positions, in two adjacent blades 32, the first side of one blade 32 is connected to the second side of the other blade 32, and the opening 321 enclosed is a regular polygon.

[0065] In this way, during the switching process, the blade assembly 30 is seamlessly spliced ​​between adjacent blades 32 to avoid light leakage.

[0066] Meanwhile, the enclosed opening 321 is always a regular polygon. Therefore, whether in the maximum or minimum opening state 321, the regularity of the shape of the light-transmitting area can be guaranteed.

[0067] like Figure 6 and Figure 7 As shown, in some alternative embodiments, the transmission assembly 40 includes a rotating element 42.

[0068] The rotating component 42 is rotatably mounted on the cover plate. The rotating component 42 is connected to all the blades 32 respectively, so that when rotating, it drives all the blades 32 to move synchronously.

[0069] This design ensures the coordination and consistency of the movement of blade 32, avoids gaps or misalignments caused by asynchronous movement of blade 32, improves the reliability and durability of the opening and closing mechanism 100, and provides users with a smooth user experience.

[0070] In some alternative embodiments, the cover plate 10 and the rotating member 42 are located on opposite sides of the blade assembly 30. A first guide structure 70 is provided between the cover plate 10 and each blade 32. A second guide structure 80 is provided between each blade 32 and the rotating member 42. When the rotating member 42 rotates, the blade 32 moves along a composite direction of the guide direction of the first guide structure 70 and the guide direction of the second guide structure 80.

[0071] Specifically, when the rotating component 42 rotates, it drives the blade 32 to move in a specific direction via the second guide structure 80, while the first guide structure 70 on the cover plate 10 further constrains the movement of the blade 32, causing it to run along a composite path of the two guide directions. The guide directions of these two guide structures have a certain angle between them, ensuring that the blade 32 can perform precise composite motion along a predetermined trajectory.

[0072] This design not only improves the smoothness and precision of the blade 32's movement but also avoids misalignment that might occur due to a single guiding direction. For example, in the open state, all blades 32 can smoothly expand to the position of the maximum opening 321; while in the closed state, they can be tightly closed to completely block the light source or form the minimum opening 321. Through the coordinated operation of the first guiding structure 70 and the second guiding structure 80, the blades 32 can smoothly switch between the maximum opening 321 and the minimum opening 321, while ensuring that the shape of the light-transmitting area is regular and uniform.

[0073] In some specific embodiments, the first guide structure 70 includes a first guide rail 71 and a first slider 72. The first guide rail 71 is formed on one of the cover plate 10 and the blade 32. The first slider 72 is formed on the other of the cover plate 10 and the blade 32, and the first slider 72 engages within the first guide rail 71.

[0074] In some more specific embodiments, a first guide rail 71 is formed on the cover plate 10, and a first slider 72 is formed on the blade 32. In this case, since the first guide rail 71 is fixed to the relatively stable part of the cover plate 10, it provides a stable motion reference for the first slider 72, making the blade 32 more stable and smooth during movement.

[0075] Alternatively, in some embodiments, the first guide rail 71 is disposed on the blade 32, and the first slider 72 is disposed on the cover plate 10.

[0076] Optionally, the first slider 72 can be designed in various forms according to different needs, and the first guide rail 71 is constructed to fit the first slider 72.

[0077] For further optimization, refer to Figure 1 and Figure 9 The first slider 72 is elongated, and the first guide rail 71 is an extended strip. This design allows the first slider 72 to slide smoothly along the extension direction of the first guide rail 71, thereby further improving the accuracy and stability of the blade 32's movement. Simultaneously, the cooperation between the elongated first slider 72 and the strip-shaped first guide rail 71 effectively distributes force, reduces local stress concentration, and thus reduces wear between the first slider 72 and the first guide rail 71, extending their service life. Furthermore, the elongated first slider 72 also increases the sliding contact area to a certain extent, thereby improving the guiding accuracy during movement, avoiding misalignment caused by shaking or offset, and ensuring consistent smoothness and reliability of the opening and closing mechanism 100's operation.

[0078] The second guide structure 80 includes a first guide rail 81 and a second slider 82. The first guide rail 81 is formed on one of the rotating member 42 and the blade 32. The second slider 82 is formed on the other of the rotating member 42 and the blade 32, and the second slider 82 is fitted within the first guide rail 81.

[0079] Combination Figure 6 and Figure 7 The first guide rail 81 is mounted on the rotating component 42, providing a stable movement path for the blade 32. The first guide rail 81 on the rotating component 42 can be set according to the desired movement trajectory of the blade 32 to achieve a specific opening and closing effect. The second slider 82 on the blade 32 slides along these rails to ensure that the blade 32 moves along the preset path and to prevent the blade 32 from deviating or getting stuck during movement.

[0080] Conversely, if the first guide rail 81 is located on the blade 32, and the second slider 82 is located on the rotating member 42, the motion guidance function can also be achieved.

[0081] Optionally, the second slider 82 can be designed in various forms according to different needs, and the first guide rail 81 is constructed to fit the structure of the second slider 82.

[0082] Furthermore, the second slider 82 is elongated, and the second guide rail 81 is also elongated. This design allows the second slider 82 to slide smoothly along its extension direction within the second guide rail 81, thereby further improving the accuracy and stability of the blade 32's movement. Simultaneously, the cooperation between the elongated second slider 82 and the elongated second guide rail 81 effectively distributes force, reducing localized stress concentration and thus decreasing wear between the second slider 82 and the first guide rail 81, extending their service life. Additionally, the elongated second slider 82 increases the sliding contact area to some extent, thereby improving guiding accuracy during movement, preventing misalignment caused by wobbling or offset, and ensuring consistent smoothness and reliability in the operation of the opening and closing mechanism 100.

[0083] In some alternative embodiments, one of the first slider 72 and the second slider 82 is a linear column and the other is a cylinder.

[0084] When the first slider 72 is a linear column, the first slider 72 is set along the extension direction of the first guide rail 71.

[0085] This configuration allows the first slider 72 to fully utilize the length of the first guide rail 71, providing higher guiding accuracy and stability. Because the linear column has a larger contact area with the strip guide rail, the force is more evenly distributed, effectively reducing localized wear and improving the system's durability. Simultaneously, the linear column design also provides stronger anti-deviation capability during the movement of the blade 32, ensuring that the blade 32 always remains on the predetermined path, improving the opening and closing effect of the opening and closing mechanism 100.

[0086] At this time, the second slider 82 adopts a cylindrical design, so that the cylindrical second slider 82 can rotate flexibly in the first guide rail 81.

[0087] Combination Figure 1 , Figures 6-9 The first slider 72 is a linear column, and the second slider 82 is a cylinder. The combination of the two enables dual control of the position and angle of the blade 32, improving the reliability of the opening and closing structure.

[0088] When the second slider 82 is a linear column, the second slider 82 is set along the extension direction of the first guide rail 81.

[0089] This configuration allows the second slider 82 to fully utilize the length of the first guide rail 81 for stable guidance. Because the linear column has a large contact area with the strip guide rail, the force is more evenly distributed, effectively reducing localized wear and improving the system's durability. Simultaneously, the linear column design provides stronger resistance to deviation during the blade 32's movement, ensuring that the blade 32 always remains on the predetermined path, thus improving the opening and closing effect of the opening and closing mechanism 100.

[0090] The first slider 72 adopts a cylindrical design, so that the cylindrical first slider 72 can rotate flexibly in the first guide rail 71.

[0091] By constructing the second slider 82 as a linear column and the first slider 72 as a cylinder, the two are combined to achieve dual control of the position and angle of the blade 32, thereby improving the reliability of the opening and closing structure.

[0092] Alternatively, both the first guide rail 71 and the first guide rail 81 are straight tracks, and the angle between them is an acute angle.

[0093] The use of a linear track allows the slider to move along a predetermined composite fixed path.

[0094] Combination Figure 7 and Figure 9 When the angle between the first guide rail 71 and the first guide rail 81 is an acute angle, the blade 32 will be guided by two different directions during the movement, which will allow the blade 32 to rotate and achieve fine control over the shape and size of the light-transmitting area.

[0095] According to some optional embodiments of the present invention, combined with Figure 6 , Figure 7 and Figure 10 The transmission assembly 40 is provided with a rack 43. The opening and closing mechanism 100 also includes a driving member 51 and a driving gear 52. The driving gear 52 is connected to the driving member 51 and meshes with the rack 43 to drive the transmission assembly 40 to rotate.

[0096] Here, the transmission assembly 40 is used to convert the operating force into the actual motion of the blade 32.

[0097] Specifically, the drive unit 51 outputs force to make the drive gear 52 rotate, and the drive gear 52 transmits the force to the rack 43.

[0098] More optimally, rack 43 is mounted on rotating member 42, and drive gear 52 meshes with rack 43. Thus, the rotational force of drive member 51 can be converted into rotation of rotating member 42, controlling the opening and closing of blade 32.

[0099] In some alternative embodiments, such as Figure 1 and Figure 11 As shown, the opening and closing mechanism 100 also includes a bracket 60. The bracket 60 is connected to the cover plate 10, and the bracket 60 is provided with a clearance opening 61 facing the window 11. The clearance opening 61 is used to provide a path for the light from the light-emitting unit, ensuring that the light can pass smoothly through the window 11, while avoiding the bracket 60 from blocking or interfering with the light path.

[0100] The transmission assembly 40 and the blade assembly 30 are installed between the bracket 60 and the cover plate 10. The bracket 60 and the cover plate 10 form an installation space. Placing the transmission assembly 40 and the blade assembly 30 in the installation space can reduce the interference of external factors, such as dust and mechanical collisions, on these components, which helps to keep the transmission assembly 40 and the blade assembly 30 clean and operate normally, and extend their service life.

[0101] At the same time, this design makes the entire lamp structure more compact and efficient, which helps to optimize the internal space layout of the lamp.

[0102] See Figure 11 At least one of the bracket 60 and the cover plate 10 is provided with a guide groove 62, and the transmission assembly 40 is provided with a guide post 44 that is fitted in the guide groove 62.

[0103] The cooperation between the guide groove 62 and the guide post 44 provides a precise guiding path for the transmission assembly 40. Whether the opening or closing mechanism 100 is in operation, the guide post 44 moves along the trajectory of the guide groove 62, ensuring that the transmission assembly 40 and the blade assembly 30 connected to it can move smoothly and accurately according to the preset path, thereby improving the operating accuracy of the entire system.

[0104] Optionally, the rotating disk is provided with guide posts 44, and the bracket 60 is provided with guide grooves 62, which extend circumferentially. The guide posts 44 on the rotating disk are inserted into the guide grooves 62 on the bracket 60, and the guide grooves 62 are circumferentially arranged, so that the rotating disk can rotate along a predetermined circular trajectory. This arrangement ensures that the rotating disk always maintains a precise rotation path during operation, avoiding deviation or shaking.

[0105] According to the second aspect embodiment of the present invention, the vehicle's headlights adopt the opening and closing mechanism 100 of the headlights in the first aspect embodiment of the present application.

[0106] It is worth noting that the specific type of vehicle referred to in this application is not limited. For example, a vehicle can be a passenger car, a public transportation vehicle, a special vehicle, etc. The vehicle according to this utility model embodiment, utilizing the improved opening and closing mechanism 100, can flexibly control the light-transmitting area of ​​the headlights. For example, when driving at night, the position of the blades 32 can be adjusted to reduce glare and avoid interfering with other drivers; while in scenarios requiring high-brightness lighting, the blades 32 can be fully opened to provide maximum luminous flux.

[0107] In some optional embodiments, the light-emitting unit is a high / low beam module. When the environment is dark, the opening / closing mechanism 100 opens the blade assembly 30 to expose the high / low beam lens module, thereby ensuring the illumination effect of the high / low beam lens module. When the environment is daytime, the opening / closing mechanism 100 closes the blade assembly 30 to block the high / low beam lens module, thereby preventing the high / low beam lens from being directly exposed to sunlight and preventing sunlight from passing through the inner lens or bright coating to ablate the plastic components inside the lamp.
