Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle lighting technology, and in particular to a transmission mechanism, vehicle lighting device, and vehicle. Background Technology
[0002] With the development of automotive technology, some cars are now equipped with intelligent headlights. Intelligent headlights refer to headlight devices that, in addition to their basic lighting function, also have features such as adaptive dimming and projection. By setting up intelligent headlights, the lighting functions of a car can be enriched, and the car's technological feel can be enhanced.
[0003] For example, a vehicle lighting system may include a light source and a transmission mechanism. The transmission mechanism can dynamically adjust and control the direction of the light beam, such as adjusting the beam's direction and height, switching between high and low beams, and projecting specific patterns or information onto the road surface. The transmission mechanism may include a transmission component and a fixed component. The transmission component can rotate relative to the fixed component, and optical elements, such as lenses and reflective elements, can be fixed on the transmission component. The transmission component drives the optical elements to rotate, thereby achieving dynamic adjustment and control of the light beam. The fit between the transmission component and the fixed component usually requires damping to ensure the stability of the transmission component during rotation. However, with increased use, the damping is easily worn down, the damping effect weakens or even fails, affecting the performance and user experience of the vehicle lighting system. Utility Model Content
[0004] This application provides a transmission mechanism, a vehicle lighting device, and a vehicle that can achieve automatic wear compensation, ensure the stability of the damping effect between the damping component and the transmission component, and avoid the problem of weakened or failed damping effect due to wear of the damping component.
[0005] The first aspect of this application provides a transmission mechanism, including: a base, a damping element, a transmission element, and an adjusting element. The damping element is disposed on the base, and the transmission element is rotatably coupled with the damping element and the base. The transmission element can rotate relative to the base and the damping element, so that the transmission element can drive the lens assembly on it to rotate together relative to the base and the damping element. The rotation of the transmission element and the lens assembly can realize dynamic adjustment and control of the beam shape, size, and direction, etc., to achieve dynamic and controllable dimming.
[0006] A damping element surrounds the transmission component. The damping element includes a discontinuous first end and a second end, which are not directly connected and may have a gap between them. In other words, the ring-shaped damping element has a discontinuous section. The first end is fixed to a base, and the second end engages with the base via an adjusting element. The adjusting element is configured to provide a pushing force to the second end, causing it to move towards the first end along the circumferential direction of the damping element. This pushing force allows the damping element to grip the transmission component tightly, ensuring a close and consistent contact between the inner surface of the damping element and the outer surface of the transmission component. This increases the friction between the damping element and the transmission component, achieving excellent damping performance, ensuring the stability and impact resistance of the transmission component during rotation, and reducing or preventing swaying of the transmission component (and lens assembly).
[0007] Furthermore, even with prolonged use, if wear occurs on the inner surface of the damping component, creating a gap between the damping component and the transmission component, the adjusting force can move the second end of the damping component towards the first end. This reduces the size of the space enclosed by the damping component, compensating for the gap and achieving automatic wear compensation. This ensures the damping component remains firmly engaged with the transmission component, achieving adaptive adjustment of the engagement force. It maintains high friction between the damping component and the transmission component, ensuring stable damping performance and preventing the damping effect from weakening or failing due to wear. This enhances the stability and reliability of the transmission mechanism and improves the performance and long-term stability of the vehicle lighting system.
[0008] In addition, the damping element surrounds the outer periphery of the transmission element, that is, the damping element wraps tightly around the outer circumference of the transmission element. The contact area between the damping element and the transmission element is large, which helps to increase the friction between the damping element and the transmission element and further improve the damping effect.
[0009] In one possible implementation, the base includes a bottom wall with a first mounting hole. A damping element is disposed on the inner surface of the bottom wall, surrounding the first mounting hole. A transmission component is fitted within the first mounting hole. This facilitates rotational engagement between the transmission component and the base, and also simplifies the structural design of the damping element surrounding the transmission component. Furthermore, with the transmission component fitted within the first mounting hole in the bottom wall and the damping element surrounding it, the overall horizontal space occupied is minimized, reducing the space occupied in the thickness direction. The arrangement of the structural components is also relatively compact, resulting in a high degree of integration and reducing the overall volume and space occupied by the transmission mechanism. This facilitates the implementation of the transmission mechanism in vehicle lighting devices and other transportation applications.
[0010] In one possible implementation, the outer surface of the transmission component has a groove surrounding its periphery, and a portion of the damping component is accommodated within this groove. Under the action of an adjusting component, the damping component tightly grips the transmission component, ensuring that a portion of the damping component is located within the groove. This allows the damping component to be stably locked within the groove. The damping component is mounted on the inner surface of the base's bottom wall. The locking fit between the damping component and the groove effectively limits the movement of the transmission component along its thickness direction, preventing it from detaching from the base and ensuring stable rotation of the transmission component relative to the base and the damping component. Furthermore, the groove also serves a positioning function, facilitating the assembly of the damping component and the transmission component and improving assembly efficiency.
[0011] In one possible implementation, the bottom wall has an abutment that protrudes from the inner surface of the bottom wall.
[0012] The adjusting component includes an elastic element with elastic deformation properties. One end of the elastic element is fixed to the second end, and the other end of the elastic element abuts against the abutting element, with the elastic element in a compressed state.
[0013] The elastic force generated by the compressed elastic element can serve as the driving force for the adjusting element, enabling the damping element surrounding the transmission element to fully and tightly grip the transmission element, achieving excellent damping effect. Furthermore, as the damping element wears down, the elastic force generated by the elastic element can push the second end of the damping element towards the first end, keeping the damping element in a state of gripping the transmission element, thus achieving adaptive adjustment of the gripping force.
[0014] In one possible implementation, the bottom wall also has a snap-fit element, which includes a connecting wall and a snap-fit wall. One end of the connecting wall is fixed to the inner surface of the bottom wall, and the snap-fit wall is fixed to the other end of the connecting wall. A receiving space exists between the snap-fit wall and the bottom wall. The damping element has a protruding snap-fit portion on its periphery, located within the receiving space. The snap-fit element and the bottom wall can thus limit the movement of the damping element along its thickness direction, improving the assembly stability of the damping element on the base.
[0015] In one possible implementation, the bottom wall also has a shielding member, which protrudes from the inner surface of the bottom wall and is located on the side of the second end facing the first end. The shielding member can shield and protect the second end and the elastic member located between the second end and the abutment member, preventing other structural members from affecting the movement of the second end of the damping member toward the first end. This can better ensure that the damping member always maintains a state of gripping the transmission member and realize the adaptive adjustment of the gripping force.
[0016] There is a gap between the second end of the blocking component and the damping component to prevent the blocking component from affecting the movement of the second end and to ensure that the damping component can achieve adaptive adjustment of the clamping force.
[0017] In one possible implementation, the transmission mechanism also includes a low-friction control structure, which refers to a structure designed according to low-friction control technology, and is a structure formed by materials and / or parts (or components) that can reduce friction and wear.
[0018] At least a portion of the low-friction control structure is located within the first mounting hole and between the bottom wall and the transmission component. This means that a low-friction control structure exists between the base (bottom wall) and the transmission component. When the transmission component rotates relative to the base, it contacts the base through the low-friction control structure and rotates relative to it, thus reducing friction and wear caused by rotation between the transmission component and the base. By improving the smoothness and stability of the transmission component's rotation relative to the base, damage to the transmission component or the base is reduced, thereby enhancing the long-term stability of the transmission mechanism.
[0019] In one possible implementation, a portion of the low-friction control structure is located between the inner surface of the bottom wall and the damping element. A second portion of the low-friction control structure is positioned between the bottom wall and the damping element, allowing for contact friction between them. This reduces damage to the damping element and improves the long-term stability of the transmission mechanism.
[0020] In one possible implementation, a second mounting hole is provided on the transmission component. The transmission mechanism also includes a lens assembly, which is fixed to the transmission component. The projection of the lens of the lens assembly onto the transmission component at least partially coincides with the second mounting hole, and the projection of the lens of the lens assembly onto the bottom wall at least partially coincides with the first mounting hole. This ensures that light can pass through the first mounting hole in the bottom wall, the second mounting hole in the transmission component, and the lens before exiting.
[0021] In one possible implementation, the damping element is formed from a lubricating and wear-resistant material, which helps to improve the durability of the damping element and enhance the long-term user experience and service life of the transmission mechanism.
[0022] In one possible implementation, the outer contour shape of the damping element includes a C-shaped annular shape or a spiral shape. The resulting damping element is simple to design, easy to mold, and helps reduce processing costs.
[0023] A second aspect of this application provides a vehicle lighting device, including a light source and a transmission mechanism of any of the above claims, wherein the light source is used to emit light and transmit the light to the transmission mechanism.
[0024] A third aspect of this application provides a vehicle, including a vehicle body and the aforementioned vehicle lighting device, the vehicle lighting device being mounted on the vehicle body.
[0025] It should be understood that the second and third aspects of this application correspond to the technical solutions of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, and will not be repeated here.

[0044] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.
[0045] This application provides a means of transportation, which may include, but is not limited to, known means of transportation such as automobiles, airplanes, ships, and trains. This means of transportation may also be a newly emerging means of transportation in the future.
[0046] Among them, automobiles can be electric vehicles (EVs), pure electric vehicles (PEVs / BEVs), hybrid electric vehicles (HEVs), range-extended electric vehicles (REEVs), plug-in hybrid electric vehicles (PHEVs), and new energy vehicles, etc.
[0047] For example, in this embodiment of the application, a car is used as an example of the means of transportation.
[0048] Figure 1 This is a schematic diagram of the structure of a means of transportation provided in an embodiment of this application.
[0049] See Figure 1 As shown, the vehicle 100 may include a vehicle body 101, which can serve as the main load-bearing structure of the vehicle, providing overall strength and rigidity to the vehicle.
[0050] The vehicle 100 may also include a lighting device 102, which emits light to provide the vehicle 100 with functions such as illumination, signal / safety alerts, aesthetics, and personalization. The lighting device 102 may include headlights, taillights, and other decorative or functional lights, such as… Figure 1 The image shows an example of a headlight as the vehicle lighting device 102.
[0051] The vehicle lighting device 102 may include a light source (not shown in the figure). The light source may be one of the main components of the vehicle lighting device 102, and the light source can emit light to meet the functional requirements of the vehicle lighting device 102. The light source may be a device or component capable of emitting light, and for example, the light source may include, but is not limited to, halogen lamps, xenon lamps, light-emitting diodes (LEDs), laser lamps, etc.
[0052] The vehicle lighting device 102 may also include a transmission mechanism (or adjustment mechanism, not shown in the figure), through which light emitted by the light source can be transmitted to the transmission mechanism and then emitted to illuminate a target location (such as the ground). The transmission mechanism can adjust the shape, angle, and direction of the light beam to optimize or enrich the illumination effect of the vehicle lighting device 102.
[0053] Taking a vehicle lighting system, including pixel headlights, as an example, a transmission mechanism is needed to provide dynamically controllable dimming, achieving effects such as beam control, anti-glare, adaptive dimming lighting, and dynamic light and shadow effects. As mentioned in the background technology section above, the rotational engagement between the transmission components and fixed components of the transmission mechanism requires damping design to ensure the stability of the transmission components during rotation, as well as their stable stopping at a predetermined position. This improves impact resistance, reduces or avoids swaying of the transmission components and optical elements such as lenses, ensures illumination effect, and enhances the reliability and stability of the vehicle lighting system.
[0054] Common damping designs often employ a compression method, such as using a metal block as a damping element to press the transmission component against the fixed component, increasing the friction between them and achieving damping. However, with prolonged use, the damping component is prone to wear, weakening or eliminating the damping effect. This leads to increased noise and may even affect the functionality of the vehicle lighting system, impacting its performance and long-term user experience.
[0055] Based on this, this application provides a transmission mechanism comprising a base, a damping element, a transmission element, and an adjusting element. The damping element is mounted on the base, and the transmission element rotatably engages with the base and the damping element, allowing the transmission element and lens assemblies on it to rotate relative to the base and the damping element, thus achieving dynamically controllable dimming. The damping element surrounds the transmission element and includes a first end and a second end that are disconnected. The first end is fixed to the base, and the second end engages with the base via the adjusting element. The adjusting element provides a pushing force to the second end, propelling it towards the first end along the circumferential direction of the damping element. The pushing force provided by the adjusting element ensures that the damping element tightly grips the transmission element, and the inner surface of the damping element can fully and tightly contact the outer surface of the transmission element, increasing the friction between the damping element and the transmission element, achieving excellent damping effect, ensuring the stability and impact resistance of the transmission element during rotation, and reducing or preventing the shaking of the transmission element (and lens assemblies). Furthermore, even with prolonged use, if wear occurs on the inner surface of the damping component, creating a gap between the damping component and the transmission component, the adjusting force can move the second end of the damping component towards the first end. This reduces the size of the space enclosed by the damping component, compensating for the gap and achieving automatic wear compensation. This ensures the damping component remains firmly engaged with the transmission component, achieving adaptive adjustment of the engagement force. It maintains high friction between the damping component and the transmission component, ensuring stable damping performance and preventing the damping effect from weakening or failing due to wear. This enhances the stability and reliability of the transmission mechanism and improves the performance and long-term stability of the vehicle lighting system.
[0056] Figure 2 This is a schematic diagram of a transmission mechanism provided in an embodiment of this application.
[0057] See Figure 2 As shown, the transmission mechanism 10 includes a base 11 and a damping element 12. The base 11 serves as the main load-bearing structure of the transmission mechanism 10, providing an assembly location and stable support for the various structural components of the transmission mechanism 10. The damping element 12 is disposed on the base 11.
[0058] The transmission mechanism 10 also includes a transmission component 13, which can be assembled with optical elements. For example, the transmission mechanism 10 may also include a lens assembly 16, which may include optical elements such as lenses. The transmission component 13 can be assembled with the lens assembly 16, such as the lens assembly 16 can be fixed on the transmission component 13.
[0059] The transmission component 13 rotates in conjunction with the base 11 and the damping component 12, meaning that the transmission component 13 can rotate relative to the base 11 and the damping component 12, so that the transmission component 13 can drive the lens assembly 16 to rotate together relative to the base 11 and the damping component 12. The light emitted by the light source can pass through the lens assembly 16 and then be emitted. The rotation of the transmission component 13 and the lens assembly 16 can realize the dynamic adjustment and control of the beam shape, size and direction, etc., to achieve dynamic and controllable dimming.
[0060] Figure 3 for Figure 2 A top view of the central transmission mechanism. Figure 4 for Figure 2 A cross-sectional schematic diagram of the transmission mechanism.
[0061] Combination Figure 2 and Figure 3 As shown, the transmission mechanism 10 also includes an adjusting member 14, and a damping member 12 is arranged around the outer periphery of the transmission member 13. For example, the side of the transmission member 13 facing the damping member 12 is the outer surface of the transmission member 13, and the damping member 12 can be arranged around the outer surface of the transmission member 13. The side of the damping member 12 facing the transmission member 13 can be the inner surface of the damping member 12, and the overall outer contour shape of the damping member 12 can be a ring-like shape.
[0062] See Figure 3 As shown, the damping element 12 includes a first end 12a and a second end 12b, which are disconnected and not directly connected (see reference). Figure 5 As shown, there may be a gap between the first end 12a and the second end 12b, that is, the ring-shaped damping element 12 has a discontinuous part. For example, with the first end 12a as the first end of the ring-shaped damping element 12 and the second end 12b as the tail end of the ring-shaped damping element 12, the first end and the tail end of the damping element 12 are disconnected, making the damping element 12 a discontinuous ring-shaped structure.
[0063] Among them, see Figure 4 As shown, the damping element 12 surrounds the outer periphery of the transmission element 13. For example, the damping element 12 can be sleeved on the outside of the transmission element 13, combined with... Figure 3 As shown, the first end 12a of the damping element 12 can be fixed to the base 11, realizing the assembly of the damping element 12 and the base 11. The second end 12b of the damping element 12 can cooperate with the base 11 through the adjusting member 14. The adjusting member 14 is configured to provide a pushing force to the second end 12b, which can push the second end 12b to move towards the first end 12a along the circumferential direction of the damping element 12 (e.g., Figure 3(As shown by the dashed arrow in the diagram). The pushing force provided by the adjusting member 14 allows the damping member 12 to grip the transmission member 13 tightly. That is, under the action of the pushing force, the inner surface of the damping member 12 can fully and tightly contact the outer surface of the transmission member 13, increasing the friction between the damping member 12 and the transmission member 13, achieving excellent damping effect, ensuring the stability and impact resistance of the transmission member 13 during rotation, and reducing or avoiding the shaking of the transmission member 13 (and the lens assembly 16), etc.
[0064] Furthermore, even if the inner surface of the damping element 12 wears down, creating a gap between the damping element 12 and the transmission element 13, the pushing force of the adjusting element 14 can move the second end 12b of the damping element 12 toward the first end 12a. This reduces the size of the space enclosed by the damping element 12 to compensate for the gap, achieving automatic wear compensation. This keeps the damping element 12 tightly gripping the transmission element 13 at all times, achieving adaptive adjustment of the gripping force. This ensures a high frictional state between the damping element 12 and the transmission element 13, resulting in stable damping performance. It avoids the problem of weakened or failed damping effect due to wear of the damping element 12, enhancing the stability and reliability of the transmission mechanism 10 and improving the performance and long-term stability of the vehicle lighting device 102.
[0065] In addition, the damping element 12 surrounds the outer periphery of the transmission element 13, that is, the damping element 12 surrounds and hugs the transmission element 13 along the outer circumference of the transmission element 13. The contact area between the damping element 12 and the transmission element 13 is large, which helps to increase the friction between the damping element 12 and the transmission element 13 and further improve the damping effect.
[0066] It is understood that the inner surface contour shape of the damping element 12 can match the outer surface contour shape of the transmission element 13. For example, the outer surface of the transmission element 13 can be a near-annular shape, and the inner surface of the damping element 12 can include discontinuous annular shapes. For instance, the overall outer contour shape of the transmission element 13 can be near-annular, and the overall outer contour shape of the damping element 12 can be near-annular with both ends (such as the first end 12a and the second end 12b) broken. The damping element 12 is arranged around the periphery of the transmission element 13, and the damping element 12 can provide a radial clamping force to the transmission element 13, achieving a strong damping effect through effective friction between the damping element 12 and the transmission element 13.
[0067] Of course, in some embodiments, the overall outer contour shape of the damping member 12 and the transmission member 13 can also be other shapes, such as a square ring or an elliptical ring.
[0068] The damping element 12 can be a discontinuous ring-like structure. For example, if the outer contour shape of the damping element 12 is a ring-like structure with both ends broken, the damping element 12 can be a C-shaped ring-like structure.
[0069] Alternatively, the damping element 12 may also include multiple discontinuous ring-like structures, which may be stacked. For example, the damping element 12 may include multiple C-shaped ring-like structures, which are stacked together to form the damping element 12.
[0070] Alternatively, in some embodiments, the damping element 12 may be composed of a continuous and complete ring-like structure and a discontinuous ring-like structure. For example, the damping element 12 may include at least one discontinuous ring-like structure and at least one continuous ring structure. For instance, the damping element 12 may include at least one C-shaped circular ring structure and at least one continuous circular ring structure. The discontinuous ring-like structure and the continuous ring-like structure may be stacked to form the damping element 12.
[0071] Alternatively, in some embodiments, the damping element 12 may include a helical structure with disconnected ends. The helical structure may include one or more continuous helical bodies, and a discontinuous ring-like structure (such as a C-shaped ring structure) may be connected to each end of the helical body to form a first disconnected end 12a and a second disconnected end 12b, respectively.
[0072] In an example where the outer contour of the damping element 12 is a discontinuous, ring-like structure, such as a C-shaped ring, the damping element 12 cannot form a continuous, complete ring. The ratio of the circumference of a discontinuous damping element 12 (such as a C-shaped ring) to the circumference of a continuous ring of the same radius can be greater than 1 / 2, meaning the circumference of the damping element 12 can exceed that of a semicircle. This ensures a larger frictional contact area between the damping element 12 and the transmission element 13, improving the damping effect and facilitating adaptive adjustment of the clamping force, thus enhancing the stability of the damping effect.
[0073] For example, the ratio of the circumference of a discontinuous damping element 12 (such as a C-shaped ring structure) to the circumference of a continuous ring of the same radius can be greater than or equal to 3 / 4, so that the damping element 12 and the transmission element 13 maintain a large clamping force, which is conducive to improving the adaptive adjustment effect of the clamping force, resulting in strong damping effect and continuous and stable damping effect.
[0074] In some embodiments, the width of the ring-shaped damping element 12 in the radial direction can be approximately 1 mm to 10 mm, and the thickness of the damping element 12 can be relatively thin, so that the damping element 12 occupies less space and has better elasticity, which facilitates the assembly of the damping element 12 with the base 11 and the transmission element 13, thereby improving the durability and stability of the damping element 12.
[0075] In some embodiments, the molding material of the damping element 12 may include a lubricating and wear-resistant material, which helps to improve the durability of the damping element 12 and enhance the long-term user experience and service life of the transmission mechanism 10.
[0076] For example, the molding material of the damping element 12 may include, but is not limited to, plastic materials, colloidal materials, and metal materials. For instance, the molding material of the damping element 12 may be polyamide 46 (PA46) or thermoplastic polyester elastomer (TPEE).
[0077] It should be noted that the molding material of the damping component 12 may include one of the aforementioned plastic materials, colloidal materials, metal materials, etc. Alternatively, the molding material of the damping component 12 may include a combination of various aforementioned plastic materials, colloidal materials, metal materials, etc.
[0078] For example, the molding material of the damping element 12 may include a combination of colloidal and metallic materials. For instance, the damping element 12 may include a metallic portion and a colloidal portion.
[0079] The metal and gel components can be integrated into a single structural component, forming the damping element 12. For example, the metal and gel components can be integrally molded using methods such as in-mold injection molding or nano-molding technology (NMT) to create the damping element 12. Alternatively, the metal and gel components can be two separate structural components, which can be fixed together using methods such as threaded connections, snap-fit connections, heat fusion fixation, or adhesive bonding to form the damping element 12.
[0080] The following example illustrates the assembly method between the damping element 12, the base 11, the transmission element 13, and the adjusting element 14, using a C-shaped annular structure as an example. In examples where the shape of the damping element 12 is different, the assembly method between the damping element 12 and the aforementioned structural components can be found below.
[0081] Figure 5 for Figure 2 A schematic diagram showing the disassembled transmission mechanism.
[0082] For example, see Figure 5As shown, the base 11 may include a bottom wall 111 and a side wall 112, with the side wall 112 protruding from one surface of the bottom wall 111. For ease of description, in this embodiment, the thickness direction of the bottom wall 111 is taken as the z-direction in the figure. Along the thickness direction, the side wall 112 may be located on one surface of the bottom wall 111, with this surface serving as the inner surface of the bottom wall 111. The end face of the side wall 112 away from the bottom wall 111 may be higher than the inner surface of the bottom wall 111, thus causing the side wall 112 to protrude from the inner surface of the bottom wall 111.
[0083] The side wall 112 and the bottom wall 111 can form an accommodating space. The damping element 12 can be disposed on the inner surface of the bottom wall 111, such that the first end 12a of the damping element 12 can be fixed to the inner surface of the bottom wall 111. The damping element 12 is located within the accommodating space of the base 11 (in conjunction with...). Figure 4 (As shown).
[0084] Among them, continue to combine Figure 4 and Figure 5 As shown, a first mounting hole 1111 can be provided on the bottom wall 111. The transmission component 13 can be fitted into the first mounting hole 1111, and the damping component 12 can be arranged around the first mounting hole 1111 and the transmission component 13. This facilitates the rotational engagement between the transmission component 13 and the base 11, and also facilitates the structural design of the damping component 12 surrounding the transmission component 13. Furthermore, with the transmission component 13 fitted into the first mounting hole 1111 of the bottom wall 111 and the damping component 12 surrounding the transmission component 13, the overall space occupied in the horizontal direction (such as the direction perpendicular to the thickness direction) is reduced, which helps to reduce the space occupied in the thickness direction (such as the z-direction). Moreover, the layout between the structural components is relatively compact, and the integration is high, which helps to reduce the volume and space occupied by the entire transmission mechanism 10, and facilitates the layout of the transmission mechanism 10 in the vehicle lighting device 102 and the vehicle 100.
[0085] See Figure 5 As shown, a second mounting hole 133 can be provided on the transmission component 13, for combination with Figure 4 As shown, the lens assembly 16 is disposed on the transmission member 13. For example, at least a portion of the lens assembly 16 can be fitted into the second mounting hole 133, and the lens assembly 16 can be fixedly assembled with the transmission member 13.
[0086] In this embodiment of the application, the fixing method between the lens assembly 16 and the transmission component 13 is not limited. For example, the lens assembly 16 and the transmission component 13 can be fixedly connected by means of adhesive connection, threaded connection, snap-fit fixing, interference fit, etc.
[0087] See Figure 5As shown, in some embodiments, the lens assembly 16 may include a lens 162 and a mounting bracket 161. The lens 162 may be mounted on the mounting bracket 161, such as the lens 162 may be fixed on the mounting bracket 161. The mounting bracket 161 may be at least partially fitted into the second mounting hole 133. The mounting bracket 161 is fixed to the transmission member 13, thereby realizing the assembly and fixation of the entire lens assembly 16 and the transmission member 13.
[0088] For example, the lens 162 described above may include, but is not limited to, a spherical lens, an aspherical lens, or a lens. The number of lenses 162 may be one, or the number of lenses 162 may be multiple.
[0089] In some other embodiments, the lens assembly 16 may also include other optical elements, such as mirrors, optical diffusers, apertures, astigmatism plates, etc.
[0090] In the thickness direction (e.g., the z-direction), the vertical projection of the lens 162 on the transmission member 13 can at least partially coincide with the second mounting hole 133. Correspondingly, the vertical projection of the lens 162 on the bottom wall 111 can at least partially coincide with the first mounting hole 1111, ensuring that light can pass through the first mounting hole 1111 of the bottom wall 111, the second mounting hole 133 of the transmission member 13, and the lens 162 before being emitted.
[0091] In some embodiments, the center line of the first mounting hole 1111, the center line of the second mounting hole 133, and the center line of the damping member 12 surrounding the optical axis of the lens assembly 16 can be the same as the optical axis of the lens assembly 16, which facilitates the structural design of the entire transmission mechanism 10 and helps to improve the smoothness and stability of the rotation of the transmission member 13 and the lens assembly 16.
[0092] The transmission mechanism 10 may also include a drive device (not shown in the figure). The drive device can cooperate with the transmission component 13. The drive device can drive the transmission component 13 to rotate relative to the base 11, damping component 12, etc., thereby causing the transmission component 13 to drive the lens assembly 16 to rotate relative to the base 11, damping component 12, etc., to achieve dynamic dimming.
[0093] In some embodiments, the drive device and the transmission component 13 can be coupled via gear transmission. For example, see [link to example]. Figure 5 As shown, the transmission component 13 may have a gear structure 132. For example, the gear structure 132 may be arranged around the periphery of the transmission component 13, and the transmission component 13 as a whole may be a large gear ring.
[0094] The drive device may also have a gear structure. For example, the drive device may include a drive motor and a worm gear, and the worm gear may have a gear structure. The gear structure of the drive device can cooperate with the gear structure 132 of the transmission member 13, so that the drive device can drive the transmission member 13 to rotate.
[0095] Of course, in some other embodiments, the drive device and the transmission component 13 can also cooperate through other transmission methods, enabling the drive device to drive the transmission component 13 to rotate. For example, belt drive, chain drive, etc.
[0096] It should be noted that the rotation of the transmission component 13 relative to the base 11 and the damping component 12 can be a full revolution or more, or the rotation of the transmission component 13 relative to the base 11 and the damping component 12 may not be a full revolution, that is, the rotation angle of the transmission component 13 may be less than 360°. The transmission component 13 can rotate clockwise and / or counterclockwise relative to the base 11 and the damping component 12.
[0097] Figure 5a for Figure 2 A schematic diagram showing the disassembly of the transmission and damping components.
[0098] In some embodiments, see Figure 5a As shown, the outer surface of the transmission component 13 may have a groove 131, which surrounds the periphery of the transmission component 13, making the overall outer contour shape of the groove 131 approximately annular. Combined with... Figure 4 As shown, the damping element 12 surrounds the outer periphery of the transmission element 13. The damping element 12 can be sleeved on the outer surface of the transmission element 13, and part of the damping element 12 can be accommodated in the groove 131.
[0099] Understandably, the damping element 12 tightly grips the transmission element 13 under the action of the adjusting component. This causes part of the damping element 12 to be located within the groove 131, allowing it to be stably locked within the groove. The damping element 12 is mounted on the inner surface of the bottom wall 111 of the base 11. The locking fit between the damping element 12 and the groove 131 effectively limits the movement of the transmission element 13. This restricts the movement of the transmission element 13 along the thickness direction (e.g., the z-direction), preventing it from detaching from the base 11 and ensuring stable rotation of the transmission element 13 relative to the base 11 and the damping element 12. Furthermore, the groove 131 also serves a positioning function, facilitating the assembly of the damping element 12 and the transmission element 13 and improving assembly efficiency.
[0100] To better achieve the rotation of transmission component 13, combined with Figure 4 and Figure 5 As shown, the transmission mechanism 10 may also include a low-friction control structure 15, see [reference]. Figure 4As shown, at least a portion of the low-friction control structure 15 can be located within the first mounting hole 1111. The low-friction control structure 15 can surround the outer periphery of the transmission member 13. For example, the low-friction control structure 15 can be sleeved outside the portion of the transmission member 13 located within the first mounting hole 1111, so that the low-friction control structure 15 is located between the bottom wall 111 and the transmission member 13. That is, the transmission member 13 and the base 11 (bottom wall 111) cooperate and rotate relative to each other through the low-friction control structure 15.
[0101] The low-friction control structure 15 refers to a structure designed according to low-friction control technology, which is a structure formed from materials and / or parts (or assemblies) capable of reducing friction and wear. For example, the molding material of the low-friction control structure 15 may include materials with high lubricity and low coefficient of friction, such as a ring-shaped steel ring, nylon ring, polyoxymethylene (POM) ring, etc.
[0102] Alternatively, the low-friction structure 15 may also include components or parts designed for low friction, such as oil-impregnated bearings, annular structures with surface treatments (such as polishing or lubrication), etc.
[0103] A low-friction control structure 15 is provided between the base 11 (bottom wall 111) and the transmission component 13. When the transmission component 13 rotates relative to the base 11, it contacts the base 11 through the low-friction control structure 15 and rotates relative to it, which helps to reduce the friction and wear generated by the rotation between the transmission component 13 and the base 11. While improving the smoothness and stability of the rotation of the transmission component 13 relative to the base 11, it helps to reduce damage to the transmission component 13 or the base 11 and improves the long-term stability of the transmission mechanism 10.
[0104] In some embodiments, the low-friction control structure 15 can be fixed to the base 11 (bottom wall 111), and the transmission member 13 can rotate relative to the low-friction control structure 15 and the base 11, and the transmission member 13 and the low-friction control structure 15 come into contact and rub against each other.
[0105] Alternatively, in some embodiments, the low-friction control structure 15 can be fixed to the transmission member 13, and the transmission member 13 and the low-friction control structure 15 can rotate together relative to the base 11, with the low-friction control structure 15 contacting and rubbing against the base 11. Alternatively, in some other embodiments, a portion of the low-friction control structure 15 can be fixed to the transmission member 13, and a portion of the low-friction control structure 15 can be fixed to the base 11. The two portions of the low-friction control structure 15 can rotate together, allowing the transmission member 13 and the base 11 to rotate relative to each other, with the two portions of the low-friction control structure 15 contacting and rubbing against each other.
[0106] In some embodiments, the low-friction control structure 15 may be entirely located between the base 11 and the transmission member 13. Alternatively, in some embodiments, such as Figure 4As shown, a portion of the low-friction control structure 15 may be located between the base 11 and the transmission member 13, and a portion of the low-friction control structure 15 may be located between the bottom wall 111 of the base 11 and the damping member 12.
[0107] For example, the low-friction control structure 15 may include a first part 151 and a second part 152 connected together. The first part 151 may be located in the first mounting hole 1111 of the bottom wall 111 and be sleeved around the periphery of the transmission member 13, so that the first part 151 is located between the base 11 (bottom wall 111) and the transmission member 13.
[0108] The second part 152 may be located on the inner surface of the bottom wall 111, for example... Figure 4 As shown, the cross-sectional shape (along the thickness direction) of the low-friction control structure 15 can be approximately 7-shaped, and the second part 152 can be located between the inner surface of the bottom wall 111 and the damping member 12. It is understood that the first end of the damping member 12 is fixed to the base 11, and the second end cooperates with the base 11 through an adjusting member. As the damping member 12 wears, it will move under the action of the adjusting member (e.g., move relative to the base 11) to adaptively adjust the clamping force. Positioning the second part 152 of the low-friction control structure 15 between the bottom wall 111 and the damping member 12 allows the bottom wall 111 and the damping member 12 to achieve contact friction through the low-friction control structure 15, which helps reduce damage to the damping member 12 and improves the long-term stability of the transmission mechanism 10.
[0109] In the example where the low-friction control structure 15 is fixed to the bottom wall 111, see [example missing]. Figure 5 As shown, a receiving groove 116 can be formed on the bottom wall 111. The receiving groove 116 can be arranged around the first mounting hole 1111. The second part 152 of the low-friction control structure 15 can be fixed in the receiving groove 116, and the first part 151 can be fixed in the first mounting hole 1111. Figure 4 As shown, in the thickness direction (such as the z direction), the damping element 12 can be located on the side of the low friction control structure 15 (second part 152) facing away from the bottom wall 111, and the low friction control structure 15 can provide certain support for the damping element 12.
[0110] For example, taking the low-friction control structure 15 fixed to the bottom wall 111 as an example, in some embodiments, during actual assembly, see... Figure 5 As shown, the low-friction control structure 15 can be assembled with the base 11, and the lens assembly 16, transmission component 13, and damping component 12 can be assembled together. Then, the damping component 12 is placed on the base 11, and the damping component 12 is assembled with the base 11, thus completing the assembly of the entire transmission mechanism 10. The assembly method is simple, easy to operate, and helps to improve assembly efficiency.
[0111] In this embodiment, the first end 12a of the damping member 12 is fixed to the base 11. It should be noted that the method of fixing the first end 12a of the damping member 12 to the base 11 is not limited. For example, the first end 12a of the damping member 12 and the base 11 can be fixedly connected by adhesive connection, threaded connection, snap-fit connection, etc.
[0112] Figure 6 for Figure 2 A schematic diagram showing the separation of the damping component and the base in the transmission mechanism. Figure 7 This is a schematic diagram of the assembly of the 6 damping components and the base.
[0113] For example, see Figure 6 As shown, the first end 12a of the damping member 12 may have an outwardly protruding mounting portion 121 (facing away from the direction surrounding the center of the damping member 12), through which the damping member 12 can be threadedly connected to the base 11. For example, the mounting portion 121 may have a through hole, and the bottom wall 111 of the base 11 may have a threaded hole with internal threads. The transmission mechanism 10 may also include a fixing member 17, one end of which may have external threads, such as a screw, pin, etc.
[0114] One end of the fastener 17 can pass through the through hole in the assembly part 121, while the other end of the fastener 17 cannot pass through the through hole in the assembly part 121, so that the other end of the fastener 17 is engaged with the side of the assembly part 121 facing away from the bottom wall 111. The external thread on one end of the fastener 17 can mate with the internal thread of the threaded hole to achieve a fixed connection, such as... Figure 7 As shown, the assembly 121 and the bottom wall 111 are connected together by the fastener 17, thereby achieving a fixed connection between the first end 12a of the damping member 12 and the base 11 (such as the bottom wall 111).
[0115] Combination Figure 6 and Figure 7 As shown, the base 11 may also have an abutment 113 on its bottom wall 111, and the abutment 113 may be protruding from the inner surface of the bottom wall 111. That is, along the thickness direction (such as the z direction), the end face of the abutment 113 away from the bottom wall 111 may be higher than the inner surface of the bottom wall 111, so that the abutment 113 protrudes from the inner surface of the bottom wall 111.
[0116] The adjusting member 14 may include an elastic member 14a, which has elastic deformation properties. When subjected to an external force, the elastic member 14a can deform and generate an elastic force to restore the deformation. After the external force is removed, the elastic member 14a can restore its shape under the action of the elastic force. For example, the elastic member 14a may include, but is not limited to, a spring, an elastic gasket, a rubber part, etc.
[0117] like Figure 7 As shown, one end of the elastic element 14a can be fixed to the second end 12b of the damping element 12, and the other end of the elastic element 14a can abut against the abutment member 113, with the elastic element 14a remaining in a compressed state. The elastic force generated by the compressed elastic element 14a can serve as the driving force of the adjusting member 14, enabling the damping element 12 surrounding the transmission member 13 to fully and tightly grip the transmission member 13, achieving excellent damping effect. Furthermore, as the damping member 12 wears down, the elastic force generated by the elastic element 14a can push the second end 12b of the damping element 12 towards the first end 12a, keeping the damping element 12 in a state of gripping the transmission member 13, thus achieving adaptive adjustment of the gripping force.
[0118] In some embodiments, the abutment 113 can also be connected and fixed to the side wall 112 of the base 11, that is, the abutment 113 is connected and fixed to both the bottom wall 111 and the side wall 112 of the base 11, which helps to strengthen the strength and stability of the abutment 113, ensure the abutment action of the abutment 113 on the elastic member 14a, and improve the stability and reliability of the transmission mechanism 10.
[0119] In some embodiments, such as Figure 6 As shown, the second end 12b of the damping member 12 may have a protruding mating portion 124, and one end of the elastic member 14a may be disposed on the mating portion 124, so as to realize the assembly and mating of the second end 12b of the damping member 12 with the elastic member 14a, thereby enabling the second end 12b to engage with the base 11 through the elastic member 14a.
[0120] In some embodiments, the mating portion 124 may have a protruding guide portion 123 (see reference). Figure 5 As shown, one end of the elastic member 14a can be arranged around the guide portion 123. For example, the guide portion 123 can include a guide rod, and one end of the elastic member 14a can be sleeved on the guide rod. The guide portion 123 can play a positioning and guiding role for the elastic member 14a, ensuring that the compressed elastic member 14a can stably push the second end 12b of the damping member 12 toward the first end 12a.
[0121] In some embodiments, the abutment 113 may also have a protruding guide portion, or the abutment 113 may not have a guide portion.
[0122] In some embodiments, continue to combine Figure 6 and Figure 7 As shown, the bottom wall 111 may also have a shielding member 114. The shielding member 114 may be protruding on the inner surface of the bottom wall 111, that is, along the thickness direction (such as the z direction). The end face of the shielding member 114 away from the bottom wall 111 may be higher than the inner surface of the bottom wall 111, so that the shielding member 114 protrudes from the inner surface of the bottom wall 111.
[0123] The shielding member 114 can be located on the side of the second end 12b of the damping member 12 facing the first end 12a. The shielding member 114 can shield and protect the second end 12b, the elastic member 14a located between the second end 12b and the abutment member 113, etc., to prevent other structural members from affecting the movement of the second end 12b of the damping member 12 toward the first end 12a. This can better ensure that the damping member 12 always keeps the transmission member 13 in a tight grip, and realize the adaptive adjustment of the gripping force.
[0124] There is a gap between the blocking member 114 and the second end 12b of the damping member 12 to prevent the blocking member 114 from affecting the movement of the second end 12b and to ensure that the damping member 12 can achieve adaptive adjustment of the clamping force.
[0125] For example, such as Figure 6 As shown, the shielding member 114 may include a first shielding wall 1141 and a second shielding wall 1142. The first shielding wall 1141 and the second shielding wall 1142 may intersect, so that the outer contour shape of the shielding member 114 may be L-shaped. The first shielding wall 1141 and the second shielding wall 1142 may form a certain accommodating space, and at least a portion of the second end 12b may be located within the accommodating space, which can provide better protection for the second end 12b.
[0126] Of course, in some other examples, the outer contour shape of the masking element 114 can also be other shapes, such as C-shaped, semi-circular, checkmark-shaped, etc.
[0127] In some embodiments, combined with Figure 6 and Figure 7 As shown, the bottom wall 111 may also have a snap-fit element 115, which can limit the damping element 12 and improve the assembly stability of the damping element 12 on the base 11.
[0128] For example, see Figure 6 As shown, the snap-fit member 115 may include a connecting wall 1152 and a snap-fit wall 1151. The connecting wall 1152 protrudes from the inner surface of the bottom wall 111, that is, along the thickness direction (such as the z direction). The end face of the connecting wall 1152 away from the bottom wall 111 may be higher than the inner surface of the bottom wall 111, so that the connecting wall 1152 protrudes from the inner surface of the bottom wall 111.
[0129] One end of the connecting wall 1152 can be fixed to the inner surface of the bottom wall 111, and the snap-fit wall 1151 can be fixed to the other end of the connecting wall 1152. For example, one end of the snap-fit wall 1151 can be fixed to the other end of the connecting wall 1152, and one end of the snap-fit wall 1151 can extend in a direction away from the connecting wall 1152, so that the snap-fit wall 1151 has a certain extension length in the horizontal direction, and an accommodating space can be formed between the snap-fit wall 1151 and the bottom wall 111.
[0130] The outer periphery of the damping member 12 may have an outwardly protruding snap-fit portion 122 (facing away from the surrounding center of the damping member 12), for engagement. Figure 7 As shown, the snap-fit part 122 can be accommodated in the accommodating space formed by the snap-fit part 115 (snap-fit wall 1151) and the bottom wall 111. The snap-fit part 115 and the bottom wall 111 can limit the movement of the damping part 12 along the thickness direction (such as the z direction) and improve the assembly stability of the damping part 12 on the base 11.
