[0019] 2) the light rays can achieve good diffusion and uniform light effect after collimation without a long propagation path in the lampshade assembly, that is, the lampshade assembly can be relatively thin and form a rear-opening inner cavity cover structure, without being set as a solid lampshade assembly, which can greatly reduce the weight of the lampshade assembly.

[0020] 3) the collimated light rays have a relatively consistent emission direction, so the direction of the incident light rays of the lampshade assembly does not need to be adjusted, thereby effectively improving the structural compactness between the lampshade assembly and the collimating lens in the front-rear direction, and combining the low spacing requirement between the collimating lens and the light source assembly, without setting a large spacing, ultimately making the overall size of the combined lamp smaller in the front-rear direction and more structurally compact.

[0021] In a second aspect, the embodiments of the present application further provide a vehicle comprising the combined lamp.

[0022] Compared with the prior art, the scheme shown in the embodiments of the present application can effectively reduce the weight of the combined lamp, compress the size of the combined lamp in the front-rear direction, improve the structural compactness, and obtain better and more reliable light-emitting effect, which is beneficial to improving the use experience of the vehicle.

[0033] Compared with the prior art, the solution shown in this application is based on a combination lamp with higher structural compactness, lighter weight, and more reliable light output. After initially determining whether the vehicle is unlocked or locked, the determination structure is verified to improve the accuracy of turning on the combination lamp after the vehicle is unlocked or locked. This ensures that the function of lighting up the combination lamp in welcome mode is triggered only after the vehicle is unlocked or locked, further improving the reliability and controllability of light output, thereby enhancing the user experience.

DETAILED DESCRIPTION

[0045] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0046] In the claims, specification and above drawings of the present application, unless otherwise explicitly defined, the terms such as "first", "second" or "third" are used only to distinguish different objects, and are not used to describe a specific order.

[0047] In the claims, description, and accompanying drawings of this invention, the term "front" refers to the light emission direction of the light source assembly, and the term "rear" refers to the direction opposite to the light emission direction of the light source assembly. Other directional terms, unless otherwise explicitly defined, such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "left," "right," "clockwise," "counterclockwise," "high," and "low," are used to indicate orientation or positional relationships based on the orientation and positional relationships shown in the accompanying drawings. These are merely for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the specific scope of protection of this invention.

[0048] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0049] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0050] The inventors discovered that the light guide components used in existing front and rear combination lights are generally solid, thick-walled components. The light emitted by the light source enters directly into the solid, thick-walled component, and the diffusion and uniform light effect is achieved through the design of the light-incident surface, light-excising surface, and internal material of the thick-walled component. This is because the light emitted by the light source is directed in all directions, and the light rays incident into the thick-walled component are also in different directions. In order to make full use of these light rays and effectively diffuse them uniformly, the thick-walled component needs to provide a longer light guide path for the light, allowing the light to undergo more reflections within the thick-walled component to achieve a better light emission effect. Therefore, traditional thick-walled components are solid components and need to have larger dimensions in the front-to-back direction. This results in the thick-walled component itself being large in size, occupying more space in the front-to-back direction, and being heavy. Furthermore, this design makes it difficult to further optimize the light emission effect (especially the dynamic light emission effect), thus affecting the user experience.

[0051] To resolve the above issues, please refer to the following: Figures 1 to 9The combination lamp provided by the present application is described as follows. The combination lamp comprises a light source assembly 1, a collimating lens 2 and a lampshade assembly 3. The collimating lens 2 is arranged on the front side of the light source assembly 1 and can collimate the light emitted by the light source assembly 1. The lampshade assembly 3 has an inner cavity which is open at the back, and the lampshade assembly 3 is buckled on the front side of the collimating lens 2 to diffuse and homogenize the light emitted from the collimating lens 2.

[0052] The combination lamp of the present application can be applied to the use requirements of front combination lamps and also to the use requirements of rear combination lamps.

[0053] Compared with the prior art, the combination lamp provided by the present application has the following beneficial effects:

[0054] 1) The light source assembly 1 is a forward light-emitting assembly. After the collimation of the collimating lens 2, the light emitted by the collimating lens 2 is parallel light. The collimating lens 2 changes the direction of the light emitted by the light source assembly 1 and focuses it into parallel light, shapes the light beam, greatly improves the proportion of the light directly projected onto the lampshade assembly 3, significantly improves the light utilization rate, guarantees the light intensity, achieves better light emission effect, and guarantees the reliability of light emission.

[0055] 2) After collimation, the light can achieve good diffusion and homogenization effect without a long propagation path in the lampshade assembly 3. That is, the lampshade assembly 3 can be relatively thin and form a cover structure with an inner cavity open at the back, without being arranged as a solid lampshade assembly 3, which can greatly reduce the weight of the lampshade assembly 3.

[0056] 3) Since the collimated light has a relatively consistent emission direction, the direction of the incident light into the lampshade assembly 3 does not need to be adjusted, thereby shortening the path of the light from the collimating lens 2 to the light entrance surface of the lampshade assembly 3, effectively improving the structural compactness between the lampshade assembly 3 and the collimating lens 2 in the front-back direction, and further combining the low spacing requirement between the collimating lens 2 and the light source assembly 1, without the need to set a large spacing, ultimately making the overall combination lamp smaller in size and more compact in structure in the front-back direction.

[0057] In some embodiments, referring to Figures 1 to 9 the front side of the light source assembly 1 forms a plurality of mutually spaced light-emitting areas, the collimating lens 2 forms a plurality of collimating areas corresponding to the light-emitting areas one by one, and the lampshade assembly 3 forms a plurality of diffusion and homogenization areas 301 corresponding to the collimating areas one by one. Since the combination lamp has a plurality of light-emitting areas, the lighting sequence, lighting time and other parameters of each light-emitting area can be set by reasonably setting the control strategy, thereby forming different dynamic light emission effects and enriching the use scenarios of the welcome mode and improving the use experience.

[0058] In some embodiments, referring toFigure 1 The combined lamp further comprises a light isolation member 4, which is arranged between the light source assembly 1 and the collimating lens 2 and has a plurality of isolated light transmission areas corresponding to the light emission areas, and a first isolation wall 410 is arranged between adjacent isolated light transmission areas. By arranging the first isolation wall 410, the different light emission areas are isolated from each other, so as to avoid the problem of light leakage between adjacent light emission areas and improve the quality of lighting.

[0059] In some specific embodiments of the light isolation member 4, referring to Figure 2 and Figures 1 to 9 , the edge of the light isolation member 4 is provided with a connecting edge 420, which is fixedly connected to the vehicle body by fasteners (such as threaded fasteners) to realize the assembly of the combined lamp and the vehicle body. In specific implementation, in order to adapt to the connection with the vehicle body, one side of the connecting edge 420 is a forwardly bent flange, and the other side of the connecting edge 420 is an extension edge extending in a direction perpendicular to the front-rear direction. In addition to realizing the mounting adaptation with the vehicle body, the flange can also enhance the bending resistance of the light isolation member 4 and improve the structural strength thereof, so that the main body design of the light isolation member 4 can be made more lightweight, further compressing the size of the light isolation member 4 in the front-rear direction and improving the structural compactness.

[0060] In some embodiments, the lampshade assembly 3 described above can adopt a structure as shown in Figure 3 , which comprises an inner lampshade 310 and a thick-walled member 320 arranged on the front side of the inner lampshade 310. The inner lampshade 310 and the thick-walled member 320 both have an inner cavity opening rearward, the inner lampshade 310 is arranged in the inner cavity of the thick-walled member 320, and the inner lampshade 310 is buckled on the front side of the collimating lens 2. The inner lampshade 310 is used to realize light diffusion, and the thick-walled member 320 is used to realize uniform light.

[0061] It should be understood that uniform light refers to uniformly spreading the light of a point light source to the entire light emission surface to avoid uneven light intensity, thereby achieving uniform illumination. The principle is to enlarge or reduce the light through a lens to control the light. The diffusion function is to diffuse the light in a single direction into an infinite number of directions to make the light softer. Unlike the uniform light function, the diffusion function is not to make the light more uniform, but to make the light more widely irradiated to achieve a larger illumination range. The principle of the diffusion plate is opposite to that of the uniform light. It uses the scattering principle to reflect the light in the component to achieve the diffusion effect.

[0062] In this embodiment, the component for realizing uniform light and the component for realizing diffusion are arranged separately. The inner lampshade 310 first realizes diffusion to improve the irradiation range of the light, and then the thick-walled member 320 performs uniform light. The inner lampshade 310 and the thick-walled member 320 are designed according to their respective functional requirements, which has stronger flexibility and can more easily adjust between diffusion and uniform light.

[0063] The thick-wall member 320 is generally made of transparent plastic or glass, and the light-incident surface S3 and the light-incident surface S4 can be provided with many small edges and corners, so that the light is repeatedly refracted, thereby achieving uniform dispersion of the light. The inner lampshade 310 is generally made of PC material or PMMA material, and the surface can be provided with many small holes or grooves, so that the light is repeatedly refracted, thereby achieving diffusion of the light.

[0064] Specifically, referring to Figures 1 to 3 , the light-incident surface S1 of the inner lampshade 310 is a forwardly recessed ladder surface, and the light-incident surface S2 is a smooth plane or a granular surface; the light-incident surface S3 of the thick-wall member 320 is a forwardly recessed ladder surface, and the light-incident surface S4 is a forwardly protruding ladder surface.

[0065] Referring to Figures 1 to 5 , in some embodiments, the combined lamp further includes a decorative frame 5, the edge of the decorative frame 5 is provided with a first connecting piece 6, the edge of the inner lampshade 310 is provided with a second connecting piece 7, and the first connecting piece 6 and the second connecting piece 7 are adapted to cooperate to clasp the edge of the thick-wall member 320 forward and backward. The installation of the existing optical element generally includes the following two forms: one is that a connecting plate is extended at the edge of the optical element, and the connecting plate is fixed by a fastener; the other is that a connecting frame is provided around the optical element, and the optical element is fixed by the connecting frame. Both of the two ways need the connecting structure to occupy the space of the outer periphery of the optical element, and for the combined lamp as a whole, more assembly space is needed in the direction perpendicular to the front and back direction.

[0066] The present embodiment utilizes the front and back connection of the decorative frame 5 and the inner lampshade 310 to achieve the front and back clamping of the thick-wall member 320, which can effectively avoid the excessive protrusion of the connecting joint from the circumferences of the thick-wall member 320 and the inner lampshade 310 without affecting the light-emitting effect, thereby minimizing the circumferential size of the lampshade assembly 3 and realizing the compact design of the structure in the direction perpendicular to the front and back direction.

[0067] In some embodiments of the first connecting piece 6 and the second connecting piece 7, referring to Figures 1 to 5One of the first connecting piece 6 and the second connecting piece 7 is a first clamping plate with the clamping hole 8, the other of the first connecting piece 6 and the second connecting piece 7 is a second clamping plate with the clamping hole 8, the plate surface of the first clamping plate and the second clamping plate are parallel to the front-back direction, after assembly, the buckle 9 is clamped into the clamping hole 8, and the first clamping plate and the second clamping plate are attached to realize limiting in the front-back direction and the direction perpendicular to the front-back direction. Specifically, the first clamping plate is provided around one of the decorative frame 5 and the inner lampshade 310, and the second clamping plate is provided around the other of the decorative frame 5 and the inner lampshade 310, so as to ensure that the decorative frame 5 and the inner lampshade 310 have multiple connection points arranged around, ensure the uniformity of the connection force, and improve the reliability of assembly.

[0068] In some embodiments, the first clamping plate and the second clamping plate both extend forward, and based on this, the clamping and fitting mode is as follows:

[0069] 1-1) refer to Figure 1 The first clamping plate is arranged at the edge of the decorative frame 5, the second clamping plate is arranged at the edge of the inner lampshade 310, the buckle 9 is arranged at the inner side surface of the second clamping plate, after assembly, the outer side surface of the first clamping plate and the inner side surface of the second clamping plate are attached, and the buckle 9 is clamped into the clamping hole 8 from the outside. In this fitting mode, the buckle 9 has a guide inclined surface that gradually inclines towards the inner lampshade 310 from front to back, which facilitates guiding the first clamping plate when clamping, so that the buckle 9 is more easily clamped into the clamping hole 8; and the buckle 9 is a wedge-shaped member, the side edge of the side away from the second clamping plate is a circular arc edge, which facilitates the buckle 9 to be pulled out of the clamping hole 8 when disassembling, and reduces the difficulty of maintenance and disassembly. In addition, the first clamping plate is a trapezoidal plate with a wide back and a narrow front, and the second clamping plate is also a trapezoidal plate with a wide back and a narrow front. This trapezoidal plate design is beneficial to enhance the overall structural strength of the first clamping plate and the second clamping plate, avoid the problem of breaking the front end of the first clamping plate or the rear end of the second clamping plate during assembly, and avoid the problem of breaking the front end of the first clamping plate or the rear end of the second clamping plate caused by vibration during driving, improve the reliability of use, and prolong the service life.

[0070] 1-2) The first clamping plate is arranged at the edge of the inner lampshade 310, the second clamping plate is arranged at the edge of the decorative frame 5, and the buckle 9 is arranged at the inner side surface of the second clamping plate. After assembly, the inner side surface of the first clamping plate is attached to the outer side surface of the second clamping plate, and the buckle 9 is clamped into the buckle opening 8 from the inner side. In this matching mode, the buckle 9 has a guide slope that gradually inclines towards the inner lampshade 310 from front to back, which facilitates the guiding of the first clamping plate when clamping, so that the buckle 9 is more easily clamped into the buckle opening 8. In addition, the buckle 9 is a wedge-shaped member, and the side edge of the side away from the second clamping plate is a circular arc edge, which facilitates the disengagement of the buckle 9 from the buckle opening 8 when disassembling, thereby reducing the difficulty of maintenance and disassembly. In addition, the first clamping plate is a trapezoidal plate with a wide rear end and a narrow front end, and the second clamping plate is also a trapezoidal plate with a wide rear end and a narrow front end. This design of trapezoidal plate members is beneficial to enhancing the overall structural strength of the first clamping plate and the second clamping plate, avoiding the problem of breakage of the front end of the first clamping plate or the rear end of the second clamping plate during assembly, and avoiding the problem of breakage of the front end of the first clamping plate or the front end of the second clamping plate caused by vibration during driving, thereby improving the reliability of use and prolonging the service life.

[0071] In other embodiments, in order to avoid affecting the appearance of the front side of the combined lamp, the first clamping plate and the second clamping plate both extend rearward. Based on this, the clamping and matching mode is as follows:

[0072] 2-1) The first clamping plate is arranged at the edge of the decorative frame 5, the second clamping plate is arranged at the edge of the inner lampshade 310, and the buckle 9 is arranged at the outer side surface of the second clamping plate. After assembly, the inner side surface of the first clamping plate is attached to the outer side surface of the second clamping plate, and the buckle 9 is clamped into the buckle opening 8 from the inner side. In this matching mode, the buckle 9 has a guide slope that gradually inclines away from the inner lampshade 310 from front to back, which facilitates the guiding of the first clamping plate when clamping, so that the buckle 9 is more easily clamped into the buckle opening 8. In addition, the buckle 9 is a wedge-shaped member, and the side edge of the side away from the second clamping plate is a circular arc edge, which facilitates the disengagement of the buckle 9 from the buckle opening 8 when disassembling, thereby reducing the difficulty of maintenance and disassembly. In addition, the first clamping plate is a trapezoidal plate with a narrow rear end and a wide front end, and the second clamping plate is also a trapezoidal plate with a narrow rear end and a wide front end. This design of trapezoidal plate members is beneficial to enhancing the overall structural strength of the first clamping plate and the second clamping plate, avoiding the problem of breakage of the front end of the first clamping plate or the front end of the second clamping plate during assembly, and avoiding the problem of breakage of the front end of the first clamping plate or the front end of the second clamping plate caused by vibration during driving, thereby improving the reliability of use and prolonging the service life.

[0073] 2-2) The first clamping plate is arranged at the edge of the inner lampshade 310, the second clamping plate is arranged at the edge of the decorative frame 5, the buckle 9 is arranged at the inner side surface of the second clamping plate, after assembly, the inner side surface of the second clamping plate is attached to the outer side surface of the first clamping plate, and the buckle 9 is clamped into the clamping hole 8 from the outside.

In addition, the first clamping plate is a trapezoidal plate with a narrow back and a wide front, and the second clamping plate is also a trapezoidal plate with a narrow back and a wide front.

The first connecting member 6 and the second connecting member 7 are arranged at the remaining side edges.

[0075] In some embodiments of the first connecting member 6 and the second connecting member 7 not shown in some other figures, one of the first connecting member 6 and the second connecting member 7 is a first clamping plate with a clamping hole 8, the other one of the first connecting member 6 and the second connecting member 7 is a second clamping plate with a clamping hole 8, the plate surface of the first clamping plate and the plate surface of the second clamping plate are perpendicular to the front-back direction, after assembly, the buckle 9 is clamped into the clamping hole 8 along the front-back direction, and the first clamping plate and the second clamping plate are attached front and back to realize limiting in the front-back direction and the direction perpendicular to the front-back direction. More specifically, the buckle 9 is a multi-edge prism buckle 9, and the clamping hole 8 is a polygonal clamping hole 8 arranged in a corresponding shape.

[0076] In some embodiments of the first connecting member 6 and the second connecting member 7 not shown in some other figures, the first connecting member 6 and the second connecting member 7 are connecting plates with plate surfaces perpendicular to the front-back direction, and the first connecting member 6 and the second connecting member 7 are respectively provided with corresponding connecting holes, and the first connecting member 6 and the second connecting member 7 are fixed by fasteners (such as threaded fasteners) penetrating the connecting holes.

[0077] In some embodiments, refer to Figure 3The front side of the light source assembly 1 forms a plurality of mutually spaced L-shaped light-emitting areas, and the top corners of each light-emitting area are oppositely arranged; the collimating lens 2 forms a plurality of L-shaped collimating areas corresponding to the light-emitting areas one by one, the inner lampshade 310 forms a plurality of L-shaped first diffusion and uniform light areas 3011 corresponding to the collimating areas one by one, and the thick-walled piece 320 forms a plurality of L-shaped second diffusion and uniform light areas 3012 corresponding to the first diffusion and uniform light areas 3011 one by one. In this embodiment, by arranging the L-shaped light-emitting areas, the L-shaped collimating areas, the L-shaped first diffusion and uniform light areas 3011, and the L-shaped light-emitting areas, the profile of the light finally transmitted for a single light-emitting area is also L-shaped. By arranging a plurality of light-emitting areas and oppositely arranging the top corners, the light transmitted by the combined lamp appears to be a starry night pattern composed of a plurality of L-shaped patterns, and the pattern has more technological and fashionable feelings.

[0078] This embodiment exemplarily shows the arrangement of four light-emitting areas, wherein the extending arms of the oppositely arranged two light-emitting areas are substantially parallel. It should be understood that not only the top corners of each light-emitting area are oppositely arranged, but also the top corners of each collimating area, the top corners of each first diffusion and uniform light area 3011, and the top corners of each second diffusion and uniform light area 3012 are oppositely arranged, respectively.

[0079] In some embodiments, referring to Figure 3 , the light-incident surface S1 and the light-emitting surface S2 of the inner lampshade 310 are both arched forward to improve the effectiveness of diffusion, and the light-incident surface S3 and the light-emitting surface S4 of the thick-walled piece 320 are both arched forward to improve the effectiveness of uniform light. More specifically, under the premise of arranging a plurality of L-shaped light-emitting areas, a plurality of L-shaped collimating areas, a plurality of L-shaped first diffusion and uniform light areas 3011, and a plurality of L-shaped second diffusion and uniform light areas 3012, the light-incident surface S1 and the light-emitting surface S2 of the inner lampshade 310 and the light-incident surface S3 and the light-emitting surface S4 of the thick-walled piece 320 are also L-shaped, respectively. Based on this, referring to Figures 1 to 3 , the light-incident surface S1 of the inner lampshade 310 is a forwardly recessed ladder surface, and the light-emitting surface S2 is a smooth plane or a granular surface; the light-incident surface S3 of the thick-walled piece 320 is a forwardly recessed ladder surface, and the light-emitting surface S4 is a forwardly protruding ladder surface.

[0080] In some embodiments, referring to Figure 1 , the light source assembly 1 includes a light source plate 110 and a controller 120 arranged on the rear side of the light source plate 110, the controller 120 is electrically connected with the light source plate 110, and a point light source is arranged on the front side of the light source plate 110. The light source plate 110 and the controller 120 are pre-assembled into an integral light source assembly 1, and the light source plate 110, the light-blocking piece 4, and the collimating lens 2 are respectively provided with mutually corresponding mounting holes, and the light source plate 110, the light-blocking piece 4, and the collimating lens 2 are fixedly connected by fasteners (such as threaded fasteners) penetrating through the mounting holes.

[0081] More specifically, the rear side of the collimating lens 2 is provided with a rear limiting column 220, and the front side is provided with a front limiting column 210. The rear limiting column 220 is in abutment with the light blocking plate, and the front limiting column 210 is in abutment with the inner lampshade 310.

[0082] More specifically, the edge of the collimating lens 2 is provided with a rear-bent limiting protrusion 230, and the edge of the light blocking piece 4 is provided with a limiting gap 401 that is adapted to be inserted into the limiting protrusion 230. The limiting protrusion 230 cooperates with the limiting gap 401 to limit the collimating lens 2 and the light blocking piece 4 in a direction perpendicular to the front-rear direction, so that the mounting holes on the collimating lens 2 and the mounting holes on the light blocking piece 4 correspond to each other.

[0083] More specifically, the controller 120 and the vehicle control module interact information through the CAN network (i.e. wireless form of information interaction), and there can be no hard-wired connection between the controller 120 and the vehicle control module. The traditional hard-wire driving mode realizes the information interaction between the light source and the vehicle control module through a real cable, which is difficult to realize the driving demand of complex dynamic light-emitting effect. However, the wireless interaction mode of the embodiment can meet the more complex dynamic light-emitting demand. The specific use process is as follows: after the vehicle control module receives the light-emitting request signal, the signal instruction is sent to the controller 120 of the combination lamp through the CAN network. After the controller 120 of the combination lamp accepts the instruction, different PWM waveforms are output to control the brightness and on-off of the LED.

[0084] In some specific embodiments, referring to Figure 2 and Figure 1 , in order to correspond to different combination lamps (i.e. the number of light blocking pieces 4 corresponds to the number of combination lamps), the light blocking piece 4 has multiple, and the multiple light blocking pieces 4 are distributed along a direction perpendicular to the front-rear direction, and a third isolation wall 440 is arranged between adjacent two light blocking pieces 4. More specifically, the adjacent light blocking pieces 4 are integrally arranged.

[0085] In some specific embodiments, referring to Figure 2 and Figures 1 to 9 , each light-emitting area has at least two point light sources, each isolation light-transmitting area forms an independent light-transmitting area 402 corresponding to the point light source, and a second isolation wall 430 is arranged between adjacent two independent light-transmitting areas 402 to avoid the problem of light leakage when the light-emitting area is illuminated in a flowing water form. In specific implementation, the independent light-transmitting area 402 is a circular hole-shaped light-transmitting area, and the inner diameter is 4mm-10mm (for example, 4.5mm, 5mm, 6mm, 11mm, 7mm, 9mm), which avoids the interference between the light blocking piece 4 and the point light source caused by too small hole diameter, and also avoids the problem of affecting the uniformity of light-emitting caused by too large hole diameter.

[0086] In some embodiments, referring to Figure 9The light source assembly 1 comprises a light source plate 110 and a controller 120 arranged at the rear side of the light source plate 110, the controller 120 is electrically connected with the light source plate 110, the front side of the light source plate 110 forms a plurality of light-emitting areas spaced from each other, the collimating lens 2 forms a plurality of collimating areas corresponding to the light-emitting areas one by one, and the inner lampshade 310 forms a plurality of first diffusion uniform light areas 3011 corresponding to the collimating areas one by one; the thick-walled member 320 comprises a plurality of thick-walled elements 321, the thick-walled elements 321 correspond to the first diffusion uniform light areas 3011 one by one, and each thick-walled element 321 is formed with a second diffusion uniform light area 3012, the second diffusion uniform light area 3012 corresponds to the first diffusion uniform light area 3011 one by one; the edges of each thick-walled element 321 are respectively formed with crimping edges, the crimping edges located at the opposite sides of the thick-walled element 321 are defined as inner crimping edges 3211, and the remaining crimping edges are outer crimping edges 3212; the decorative frame 5 comprises an outer frame 510 and a middle frame 520 arranged in the outer frame 510, the outer frame 510 cooperates with the edges of the inner lampshade 310 to clampingly fix the outer crimping edges 3212, and the middle frame 520 cooperates with the inner lampshade 310 to clampingly fix the inner crimping edges 3211.

[0087] In some embodiments, referring to Figure 8 In the direction perpendicular to the front-rear direction, the cross section of the thick-walled element 321 is also L-shaped, the thick-walled element 321 is integrally arranged with the second diffusion uniform light area 3012, and the front side of the thick-walled element 321 is the second diffusion uniform light area 3012. Based on this, the width A of the two extension arms of the thick-walled element 321 is 7mm-14mm (for example, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm), which ensures the sharpness of the visual effect and also effectively guarantees the formability and reduces the manufacturing difficulty; the width of the gap (i.e. the space that can accommodate the middle frame 520) between the two adjacent thick-walled elements 321 is 3mm-9mm (for example, 4mm, 5mm, 6mm, 7mm, 8mm), which ensures that the middle frame 520 can be effectively fixed without producing the phenomenon of powdering under the working condition of vehicle vibration.

[0088] More specifically, the width of the two extension arms of the thick-walled element 321 gradually increases in the direction towards the top corner thereof, forming an extension arm with a trapezoidal cross section, which on the one hand can improve the structural strength of the extension arm itself and avoid breakage at the top corner, and on the other hand, the thick-walled element 321 is usually manufactured by injection molding process, and this design can also reduce the difficulty of demolding.

[0089] In some embodiments, referring to ​The collimating lens 2 is a Fresnel lens, which has a plurality of collimating light transmission parts corresponding to the point light sources one by one, and each collimating light transmission part includes a plurality of concentric circular rings arranged concentrically and distributed in a stepped manner. The front-rear gap between the light source plate 110 and the collimating lens 2 is 1.4mm-3.5mm (for example, 1.5mm, 1.9mm, 2.2mm, 2.8mm, 3.2mm). If the gap is too small, the collimating lens 2 is easily broken due to excessive extrusion of the light blocking piece 4 during installation, which seriously affects the optical efficiency, the light emission effect, and the driving cost. Similarly, if the gap is too large, the optical efficiency is also affected, and the driving cost is increased.

[0090] The design principle of the Fresnel lens is based on the Fresnel zone plate. By allowing the refractive energy of the lens to occur only on the optical surface, the curvature of the surface is preserved, and the effective convergence of light rays is achieved. This design not only reduces the use of optical materials, but also makes the lens lighter, thinner and more compact. In terms of light control, the Fresnel lens can convert the conical divergent light of the light source into almost parallel light, while improving the brightness. In terms of light uniformity, the Fresnel lens makes the brightness of the entire light beam relatively consistent at each part. In terms of economic applicability, the Fresnel lens is small in size, easy to assemble, and more economical.

[0091] More specifically, the length of each light emission area in the first direction is less than the length in the second direction. On the light source plate 110, the distribution surface occupied by all point light sources is an elongated surface with a length in the second direction greater than a length in the first direction. The collimating light transmission parts on the collimating lens 2 are also correspondingly distributed. The first direction and the second direction are both perpendicular to the front-rear direction, and the second direction is perpendicular to the first direction. Based on this, in the first direction, the center distance F between adjacent two collimating light transmission parts is 17mm-27mm (for example, 18mm, 19mm, 22mm, 24mm, 25mm); in the second direction, the center distance G between adjacent two collimating light transmission parts is 10mm-22mm (for example, 11mm, 13mm, 16mm, 19mm, 21mm). By reasonably setting the two center distances, the uniformity of the lighting effect is ensured, the optical efficiency is improved, and the economy of use is improved.

[0092] Based on the same inventive concept, the embodiment of the present application further provides a vehicle comprising the combined lamp.

[0093] The vehicle provided by the embodiment can effectively reduce the weight of the combined lamp, compress the size of the combined lamp in the front-rear direction, improve the structural compactness, and obtain better and more reliable light emission effect, thereby improving the use experience of the vehicle.

[0094] Based on the same inventive concept, the embodiment of the present application also provides a combination lamp control method, which is based on the combination lamp described above and comprises the following steps:

[0095] Obtaining vehicle state information, which includes whether the vehicle is unlocked and whether the vehicle is locked;

[0096] If it is determined that the vehicle is unlocked or the vehicle is locked, the obtained vehicle state information is rechecked and verified to determine whether the vehicle state information is authentic;

[0097] If the rechecking and verification result determines that the vehicle state information is authentic, the light source assembly 1 is controlled to be lit in a welcome mode.

[0098] Compared with the prior art, the combination lamp provided by the embodiment is based on a combination lamp that is more compact, lighter in weight, and has more reliable light emission effect. After initially determining that the vehicle is unlocked or locked, the combination lamp is verified to improve the accuracy of the combination lamp being turned on after the vehicle is unlocked or locked, to ensure that the function of the combination lamp being lit in a welcome mode is triggered only after the vehicle is unlocked or locked, to further improve the reliability and controllability of light emission, and to further improve the user experience.

[0099] Specifically, if the vehicle control module determines that the vehicle state information is authentic through rechecking and verification, the vehicle control module sends a CEM light show request signal to the controller 120 of the combination lamp through the CAN network, and the controller 120 of the combination lamp controls the light source board 110 to be lit in a welcome mode. Multiple welcome modes can be supported, and the light show effect can be upgraded through FOTA.

[0100] In some embodiments, the combination lamp comprises a light source assembly 1, a collimating lens 2, and a lampshade assembly 3. The collimating lens 2 is arranged on the front side of the light source assembly 1 to collimate the light emitted by the light source assembly 1. The lampshade assembly 3 has an inner cavity that is open to the rear. The lampshade assembly 3 is arranged on the front side of the collimating lens 2 to diffuse and homogenize the light emitted from the collimating lens 2. The front side of the light source assembly 1 forms a plurality of mutually spaced light emission zones. The collimating lens 2 forms a plurality of collimating zones corresponding one-to-one to the light emission zones. The lampshade assembly 3 forms a plurality of diffusion and homogenization zones 301 corresponding one-to-one to the collimating zones. Each light emission zone has at least two point sources arranged sequentially along a predetermined direction.

[0101] The welcome mode includes one of a first mode, a second mode, and a third mode;

[0102] In the first mode, the plurality of light emission zones are sequentially lit in a first predetermined order;

[0103] In the second mode, the point sources in the light emission zones are sequentially lit in a predetermined direction in a water flow form;

[0104] In the third mode, the lighting form of the light-emitting area includes a flashing breathing form and an overall lighting form, and the flashing breathing form and the overall lighting form are alternately performed according to a third preset sequence.

[0105] In the third mode, the lighting form of the light-emitting area includes a flashing breathing form and an overall lighting form, and the flashing breathing form and the overall lighting form are alternately performed according to a third preset sequence.

[0106] In specific implementation, four light-emitting areas are taken as an example:

[0107] For the first mode, the four light-emitting areas can be controlled and lighted individually, and a rotating special effect is added to the dynamic light-emitting effect. The four light-emitting areas can rotate clockwise or counterclockwise in turn, and the interval lighting period of the four light-emitting areas is 20 ms to 30 ms. The rotating effect is more delicate, the frame rate of the dynamic effect is between 15 S and 20 S, and the overall fluency is better.

[0108] For the second mode, the four light-emitting areas are in the form of overall water flow, and the point light source is lighted one by one along the first preset direction (for example, from top to bottom). The water flow is completed in 180 ms to 220 ms, forming a uniform and delicate light flow effect. The point light source is lighted one by one along the first preset direction (for example, from left to right), and the left and right water flows are completed in 90 ms to 110 ms, forming a uniform and delicate light flow effect.

[0109] For the third mode, after the controller 120 of the combined lamp receives the CEM light show request signal, the overall flashing breathing is performed twice within 20 ms, then the overall lighting form is presented for 5 s, and then the overall flashing breathing is performed twice within 20 ms.

[0110] In some embodiments, the process of checking and verifying the obtained vehicle state information needs to be completed within a certain time range to avoid affecting the timeliness of triggering the welcome mode. Specifically, the duration of checking and verifying the obtained vehicle state information is 0.5 ms to 1.2 ms (for example, 0.8 ms, 1 ms, 1.1 ms).

[0111] In some embodiments, the process of checking and verifying the obtained vehicle state information to determine whether the vehicle state information is real can be divided into two scenes: unlocking and locking. Taking the unlocking scene as an example, the checking and verifying specifically includes:

[0112] If the unlocking signal is obtained and it is determined that the vehicle is unlocked, it is checked and verified whether the vehicle lock is unlocked;

[0113] If the vehicle lock is in the unlocked state, it is determined that the vehicle state information is real;

[0114] Taking the car locking scene as an example, the rechecking and verifying specifically includes:

[0115] If the car locking signal is acquired and it is judged that the whole vehicle is locked, it is checked and verified whether the vehicle lock is locked;

[0116] If the vehicle lock is in the locked state, it is judged that the whole vehicle state information is real.

[0117] In some embodiments, acquiring the whole vehicle state information specifically includes:

[0118] If the unlocking function is triggered by the vehicle key, it is judged that the whole vehicle is unlocked;

[0119] If the locking function is triggered by the vehicle key, it is judged that the whole vehicle is locked.

[0120] More specifically, triggering the unlocking function or the locking function by the vehicle key can be achieved by the unlocking button or the locking button on the vehicle key; or, by using the keyless entry function, the unlocking function or the locking function can be achieved by touching the door handle.

[0121] The application solves the problems of traditional front and rear combination lamps, such as not delicate appearance, uneven light emission, large weight and high cost, can realize various smooth dynamic lighting effects, and has stronger delicate feeling; the overall weight of the combination lamp can be reduced by 30% compared with the traditional combination lamp structure, the light uniformity Lmax / Lmin=1.64<2.5 (industry level standard value); the smoothness of the dynamic effect frame rate is between 15s and 20s, realizing the uniformity of the human eye visual effect.

[0122] The above only describes the preferred embodiments of the application and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
