[0002] In recent years, consumers have more personalized demands for transportation lamps (such as vehicle lights), such as near-field welcome lights, angel wings and other atmosphere lights that are deeply loved by consumers. However, some display parameters of existing projection modules (such as focal length, field of view, brightness, etc.) may usually be set at the factory, but in actual applications, for example, the projection module is not easy to adjust flexibly, which will result in poor image display effects, or display effects that are not expected by users, affecting the user experience. Utility Model Content

[0003] The embodiments of the present application provide a lens assembly, an image display system, a vehicle lamp, a vehicle lamp system and a vehicle. The lens assembly can adjust the image light output by the projection module, thereby helping to improve the display effect and user experience.

[0004] In a first aspect, an embodiment of the present application provides a lens assembly, which includes a bracket, a driving member, a worm gear, a first swing arm and a lens component. The worm gear is connected to the driving member, and the driving member is used to drive the worm gear to rotate. The first swing arm is rotatably connected to the bracket, and the first swing arm is provided with a bevel gear portion, which is used to mesh with the worm gear so that the first swing arm rotates relative to the bracket. The lens component is mounted on the first swing arm. The lens component can rotate with the first swing arm to be located on the light output path of the image light output by the projection module and adjust the image light, or be moved away from the light output path.

[0005] When the lens component is located on the light path of the image light output by the projection module, it can be regarded as being located in the working position. When the lens component is removed from the light path, it can be regarded as being located in the idle position. When the lens component is located in the working position, the lens component can dim the image light output by the projection module.

[0006] The lens assembly provided in the present application drives the first swing arm to rotate relative to the bracket through a driving member, so that the lens component can be switched between the working position and the idle position. In this way, when it is necessary to adjust the image light of the projection module, the lens component is cut into the light output path of the image light, so that without changing the display parameters of the projection module itself, the image light is adjusted by the lens assembly arranged outside the projection module, which is beneficial to improving the image display effect; when it is not necessary to adjust the image light of the projection module, the lens component is cut out from the light output path to achieve flexible switching, which can meet the various scene requirements of the projection module image display.

[0037] In recent years, consumers have more personalized demands for transportation lamps (such as vehicle lights), such as near-field welcome lights, angel wings, etc., which are very popular among consumers. However, some display parameters of existing projection modules (such as focal length, field of view, brightness, etc.) may usually be set at the factory, but in actual applications, for example, the projection module is not easy to adjust flexibly, which will cause poor image display effects, or display effects that are not expected by users, such as small field of view, small display range, insufficient brightness, or single display mode, etc., which affect the user experience.

[0038] Based on this, see Figure 1 and Figure 2 In one embodiment of the present application, an image display system 1 is provided, comprising a projection module 10 and a lens assembly 30. The projection module 10 serves as an image generation unit (PGU) for outputting image light. The lens assembly 30 is used to adjust the image light output by the projection module 10 to improve the display effect and user experience. The lens assembly 30 adjusts the image light by at least one of changing the optical path of the image light, focusing and brightening the image light, expanding the illumination range of the image light, and adjusting the color of the image light. Changing the optical path of the image light includes deflecting the image light incident on the lens assembly 30 by a specific angle.

[0039] See also Figure 3 and Figure 4The present application provides a lens assembly 30, which includes a bracket 31, a driving member 32, a worm gear 33, a first swing arm 34 and a lens component 35. The worm gear 33 is connected to the driving member 32, and the driving member 32 is used to drive the worm gear 33 to rotate. The first swing arm 34 is rotatably connected to the bracket 31, and the first swing arm 34 is provided with a bevel gear portion 341, which is used to mesh with the worm gear 33 so that the first swing arm 34 rotates relative to the bracket 31. The lens component 35 is mounted on the first swing arm 34. The lens component 35 can rotate with the first swing arm 34 to be located on the light output path of the image light output by the projection module 10 and adjust the image light, or to be moved away from the light output path.

[0040] like Figure 2 As shown, when the lens component 35 is located on the light path of the image light output by the projection module 10, it can be regarded that the lens component 35 is located at the working position. The specific position of the working position is not limited. The lens component 35 is located on the light path, and the position of the lens component 35 can be adjusted to meet various scene applications. Figure 1 As shown, after the lens component 35 is removed from the light output path, the lens component 35 can be regarded as being in the idle position. When the lens component 35 is in the working position, the lens component 35 can dim the image light output by the projection module 10. For example, in some embodiments, the lens component 35 is in the idle position, the image light projected by the projection module 10 does not pass through the lens component 35, the projection position of the image light on the projection plane is P1, and the display mode of the image display system 1 can be a normal lighting mode; when the lens component 35 is in the working position, the image light projected by the projection module 10 passes through the lens component 35, and the projection position of the image light adjusted by the lens component 35 on the projection plane is P2. Compared with P1, the distance between P2 and the projection module 10 is smaller, and the display mode of the image display system 1 can be a near-field welcoming mode or a near-field projection mode, etc.

[0041] Please continue reading Figure 3 and Figure 4 The lens assembly 30 provided in the present application drives the first swing arm 34 to rotate relative to the bracket 31 through the driving member 32, so that the lens component 35 can be switched between the working position and the idle position. In this way, when it is necessary to adjust the image light of the projection module 10, the lens component 35 is cut into the light output path of the image light, so that without changing the display parameters of the projection module 10 itself, the lens assembly 30 arranged outside the projection module 10 is conducive to improving the image display effect; when it is not necessary to adjust the image light of the projection module 10, the lens component 35 is cut out from the light output path to achieve flexible switching, which can meet the various scene requirements of the image display of the projection module 10.

[0042] In addition, by meshing the worm gear 33 with the bevel gear part 341 to achieve transmission, stepless adjustment can be achieved, thereby improving the smoothness and stability of the rotation of the first swing arm 34. When the lens component 35 is in the working position, the position of the lens component 35 can be adjusted by adjusting the rotation or swing angle of the first swing arm 34 through the driving member 32, which is beneficial to increase the application scenario range of the image display system 1. The meshing of the worm gear 33 and the bevel gear part 341 can achieve self-locking, which is beneficial to improve the position stability of the lens component 35. In this way, the image light dimmed by the lens component 35 is not easy to shake when displayed on the projection plane, which is beneficial to improve the image display effect.

[0043] In this embodiment, the first swing arm 34 can rotate relative to the bracket 31 around the first rotation axis, and the worm gear 33 can rotate relative to the bracket 31 around the second rotation axis. The second rotation axis and the first rotation axis can be, but are not limited to, perpendicular to each other.

[0044] In some embodiments of the present application, the bracket 31 is used to support the driving member 32, the worm gear 33, the first swing arm 34 and the lens component 35. The bracket 31 can be an independent structure, and the bracket 31 can also be a vehicle 100. The bracket 31 includes a mounting portion 312 and a support portion 314 protruding from one side of the mounting portion 312. The mounting portion 312 and the support portion 314 together form a light-through hole 316. The mounting portion 312 is used to connect with other structures. In the direction of the first rotation axis, the width of the mounting portion 312 is greater than the width of the support portion 314, and the driving member 32 and the worm gear 33 are located in the receiving space surrounded by the support portion 314 and the mounting portion 312. The first swing arm 34 can rotate relative to the bracket 31 around the first rotation axis. In the direction of the first rotation axis, the driving member 32 and the worm gear 33 are both located outside the light hole 316 and on the same side of the bracket 31. The driving member 32 and the worm gear 33 share the accommodation space on one side of the support portion 314, and only occupy a small side space on one side of the bracket 31. While realizing the dimming switching of the image light of the projection module 10, it can save the installation space on the side and facilitate the layout of other components. For example, the headlights of a vehicle are arranged on the front side of the vehicle. The space on the front side for arranging the headlights is relatively small, and usually there are two headlights. When the lens assembly 30 is applied to the headlights of the vehicle for dimming, the space occupied by the matching structure of the worm gear 33 meshing with the bevel gear portion 341 is relatively small, which can be more conducive to the dual-light scene of the vehicle.

[0045] The outer wall of the mounting portion 312 facing the receiving space is provided with a receiving groove 318 for receiving at least part of the driving member 32. The receiving groove 318 can be used to position the driving member 32 when the driving member 32 is mounted on the bracket 31, which is conducive to improving the convenience of assembling the lens assembly 30. It can be understood that the receiving groove 318 can be omitted, and the driving member 32 can be directly mounted on the bracket 31.

[0046] It can be understood that the present application does not limit the structure of the bracket 31. For example, the mounting portion 312 can be omitted. The bracket 31 is provided with a light-through hole 316. The first swing arm 34 rotates relative to the bracket 31 around the first rotation axis. In the direction of the first rotation axis, the driving member 32 and the worm gear 33 are both located outside the light-through hole 316 and on the same side of the bracket 31, which is beneficial to reducing the transmission distance and reducing the space occupied by the lens assembly 30.

[0047] It is understandable that the driving member 32 may be installed on other structures instead of the bracket 31. For example, when the lens assembly 30 is used in a vehicle, the bracket 31 may be a partial structure on the vehicle body.

[0048] In some implementations of this application, please refer to Figure 4 and Figure 5 In the length extension direction of the first swing arm 34, the bevel gear portion 341 includes a plurality of bevel teeth 3411, and the plurality of bevel teeth 3411 are arranged along the periphery of the first end of the first swing arm 34, and the lens component 35 is located at the second end of the first swing arm 34. The bevel gear portion 341 is integrated with the periphery of one end of the first swing arm 34, and there is no need to arrange a bevel gear separately, which is beneficial to reducing the number of components of the lens assembly 30 and simplifying the structure of the lens assembly 30.

[0049] It can be understood that the multiple helical teeth 3411 are not limited to the periphery of the first end of the first swing arm 34, that is, the helical gear portion 341 is not limited to the first end of the first swing arm 34, and the helical gear portion 341 can be set at other positions of the first swing arm 34, for example, the helical gear portion 341 is formed in the middle part of the side of the first swing arm 34 facing the bracket 31.

[0050] It can be understood that the first swing arm 34 can be rotatably connected to the bracket 31 via the first rotating shaft. The first rotating shaft can be protruded from the first swing arm 34 or the bracket 31, or the first rotating shaft can be rotatably passed through the first swing arm 34 and the bracket 31. The first swing arm 34 can rotate relative to the bracket 31.

[0051] It can be understood that the first swing arm 34 may include an arm body and a bevel gear portion 341 that are separately arranged. The bevel gear portion 341 may be a separate gear structure, and the bevel gear portion 341 is fixed to the arm body.

[0052] In some implementations of this application, please refer again to Figure 3 and Figure 4The driving member 32 includes a driving body 322 and a driving shaft 324. At least a portion of the driving body 322 is received in the receiving groove 318. The driving shaft 324 is connected to the driving body 322 and extends out of the receiving groove 318. The driving shaft 324 is connected to the worm gear 33, and the driving shaft 324 is used to drive the worm gear 33 to rotate. The driving member 32 can be a motor. It can be understood that the present application does not limit the specific type of the driving member 32. The driving member 32 can be a cylinder, an oil cylinder, etc.

[0053] In some embodiments of the present application, the lens assembly 30 further includes a second swing arm 36 rotatably connected to the bracket 31, and the lens component 35 is connected between the first swing arm 34 and the second swing arm 36. In the direction of the first rotation axis, the light hole 316 is located between the second swing arm 36 and the first swing arm 34. The lens component 35 is rotatably connected to the bracket 31 through the first swing arm 34 and the second swing arm 36, which is conducive to improving the support of both ends of the lens component 35 in the direction of the first rotation axis, and is conducive to improving the stability of the lens component 35.

[0054] It can be understood that the present application does not limit the specific structure of the first swing arm 34 and the second swing arm 36; the second swing arm 36 can also be omitted, that is, the lens component 35 can be supported only by the first swing arm 34; the number of swing arms can also be increased to improve the supporting strength of the lens component 35.

[0055] In some embodiments of the present application, the lens assembly 30 further includes a cover 37 connected to the bracket 31, the cover 37 covers the receiving groove 318, and the driving body 322 is located between the cover 37 and the bracket 31. The cover 37 is used to protect the driving member 32 and prevent the driving member 32 from detaching from the bracket 31. The cover 37 can be fixedly connected to the bracket 31 by a fastener, but is not limited to it.

[0056] In some embodiments of the present application, the worm gear 33 is located between the cover 37 and the bracket 31 . The cover 37 is used to protect the worm gear 33 and also to reduce interference of other elements outside the lens assembly 30 on the transmission between the worm gear 33 and the bevel gear portion 341 .

[0057] The lens component 35 includes at least one of a Fresnel lens, a reflector, a filter, a condenser, a diffuser, and a prism. The image light can be adjusted by one lens or a combination of two or more lenses in the lens component 35, which can support multiple scene applications, such as near-field welcoming, corner lighting, side light blankets and other new lighting scenes.

[0058] The Fresnel lens is also known as a spiral lens. One side of the Fresnel lens may be a smooth surface, and the other side of the Fresnel lens may include a wedge-shaped surface. There may be multiple wedge-shaped surfaces, and the wedge-shaped surfaces may be in a ring-shaped structure, and the multiple wedge-shaped surfaces may be arranged in multiple concentric circles. The Fresnel lens may be a thin sheet formed by injection molding of a polyolefin material, or it may be made of glass. The present application does not limit the material of the Fresnel lens. The image light directly emitted by the projection module 10 is deflected from the first light-emitting light path to the second light-emitting light path after passing through the Fresnel lens. The present application does not limit the deflection direction of the second light-emitting light path compared to the first light-emitting light path. The actual deflection angle may be determined according to the angle of the wedge-shaped surface of the Fresnel lens and / or other optical elements. For example, it may be deflected in one of the upper, lower, left, and right directions of the first rotation axis. When it is deflected to the lower side, a near-field welcome may be achieved, when it is deflected to the left or right, a light carpet lighting effect may be achieved, and when it is deflected to the upper side, a basement or outdoor projection may be achieved, and the like.

[0059] The lens component 35 may also include a frame for supporting and mounting the lens. The frame, the first swing arm 34 and the second swing arm 36 may be integrally arranged or separately arranged.

[0060] The reflector can change the direction of the light beam incident on the reflector. For example, the lens assembly 30 may include two reflectors. The two reflectors can be used to change the direction of the image light emitted by the projection module 10, thereby achieving the effect of deflecting the image light path, thereby realizing image projection near the front of the vehicle and achieving the effect of light beam deflection.

[0061] The filter can be used for filtering light. The filter can filter out unnecessary spectral components or interfering light in the light incident on the filter. The color of the image light output by the projection module 10 can also be adjusted through the filter.

[0062] A condenser can focus light and enhance the brightness of the image light. A diffuser can be used to expand the range of image light. A diffuser can focus and scatter the incident light, making the light appear diffused. The principle of a diffuser is mainly related to the microscopic morphology of the diffuser surface. The diffuser surface is provided with a microscopic structure, which includes tiny irregular or regular concave and convex structures. A prism can be used to split the image light.

[0063] A prism is a transparent object consisting of two intersecting but non-parallel planes, used to split or disperse light beams.

[0064] See also Figure 6As shown, the projection module 10 includes a light source 11, a projection chip 12 and a projection lens 13. The light source 11 is used to output light to the projection chip. The light source 11 can be an illumination light source, for example, the light source can be an illumination light source that provides illumination for the vehicle 100. The light output by the light source 11 can be monochromatic light, or the light source 11 can output light of two or more colors. The projection chip 12 is used to modulate the light input to the projection chip 12 and output image light to the projection lens 13. The projection lens 13 is used to project image light. The lens assembly 30 is used to adjust the image light output from the projection lens 13. It can be understood that the present application does not limit the structure of the projection module 10.

[0065] The projection chip 12 may be a liquid crystal on silicon (LCoS) modulator, which is a reflective spatial light modulator having the function of changing the polarization direction of incident linear polarized light. Alternatively, the projection chip may be a reflective spatial light modulator that does not have the function of changing the polarization direction of incident linear polarized light, such as a micro-electro-mechanical system (MEMS) or a digital micro mirror device (DMD). In addition, the projection chip may also be a transmissive spatial light modulator, such as a liquid crystal display (LCD). In this embodiment, the projection chip is a DMD chip.

[0066] It should be noted that the image display system 1 described above can be mainly applied to a vehicle 100. More specifically, it can be mainly applied to a smart cockpit or a vehicle light system installed on the vehicle 100. The vehicle light and the vehicle 100 provided in this application are described in detail below.

[0067] Figure 7 1 is a functional schematic diagram of a vehicle 100 according to an embodiment of the present application. Figure 7 As shown, the vehicle 100 may include various systems, each of which may include multiple components. For example, the computer system 110, the advanced driving assistance system (ADAS) 120, the sensor system 130, the lighting prompt system 140, the display system 150, one or more peripheral devices 160 (one is shown as an example), the control system 170 and the power supply 180 shown in the figure, and the above-mentioned subsystems can communicate with each other, including but not limited to wired communication and wireless communication. The vehicle 100 may also include other functional systems, such as an engine system that provides power for the vehicle 100, a cockpit, etc., which are not limited in this application.

[0068] The vehicle shown in this embodiment includes a sensor system 130, which may include a number of detection devices that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules. For example, the sensor system may include a positioning system, an inertial measurement unit (IMU), a radar, a laser rangefinder, a camera device, and the like. The sensor system may also include sensors of the internal systems of the vehicle 100 (e.g., an in-vehicle air quality monitor, a fuel gauge, an oil temperature gauge, etc.). Sensor data from one or more of these sensors can be used to detect objects and their corresponding characteristics (position, shape, direction, speed, etc.).
