DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] In the related art, interference fit is generally used to fix the shell and the light guide plate. This fit can theoretically ensure a tight connection between the shell and the light guide plate. During the driving process of the vehicle, vibrations are inevitable due to factors such as uneven road surface and engine operation. These vibrations are transmitted to the atmosphere light, causing mutual extrusion between the shell and the light guide plate. Due to the characteristics of interference fit, the gap between the shell and the light guide plate is extremely small, or even zero, so this extrusion effect is particularly obvious. Long-term mutual extrusion not only easily damages the structure of the shell and the light guide plate, but may also cause the connection between them to loosen or deform, thereby shortening the service life of the atmosphere light.

[0031] In addition, the bracket material of traditional ambient lights is mainly made of polycarbonate (PC) or polycarbonate and acrylonitrile-butadiene-styrene (ABS) copolymer materials. Therefore, when the shell of the traditional ambient light is subjected to external force, it is easy to deform and rebound, thereby causing friction and collision with the light guide plate, which not only aggravates the damage between the bracket and the light guide plate, but also produces a large abnormal noise, seriously affecting the passenger's riding experience.

[0032] To this end, some embodiments of the present invention provide an atmosphere lamp 1000, which is applied to a vehicle. Specifically, the atmosphere lamp 1000 can be installed in a vehicle door panel, a dashboard, a vehicle seat, and a floor in a vehicle compartment. Figures 1 to 13 The ambient light 1000 is illustrated.

[0033] Reference Figure 1 As shown, in the embodiment of the present invention, the overall structure of the atmosphere lamp 1000 can be in a strip shape. In addition, the atmosphere lamp 1000 can also be in a block shape, which is not limited in this embodiment. Figure 8 As shown, the atmosphere lamp 1000 includes: a shell 100 and a light guide component 200 , wherein the shell 100 is a hollow structure, the light guide component 200 is installed inside the shell 100 , and the light guide component 200 includes a light guide plate 210 and a light emitting component 220 .

[0034] Reference Figure 8 and Fig.10As shown, in the embodiment of the present invention, a mounting groove 110 is formed inside the housing 100, and a light outlet 111 connected to the mounting groove 110 is provided on one side of the housing 100. Specifically, the light outlet 111 is an opening of the mounting groove 110, and the light outlet 111 faces the front side of the atmosphere lamp 1000. Among them, the light guide plate 210 is arranged in the mounting groove 110 and is located on one side of the mounting groove 110 close to the light outlet 111. In one example, the inner wall of the mounting groove 110 is arranged around the circumference of the light guide plate 210, so the light outlet 111 is adapted to the size and shape of the light guide plate 210, and the light guide plate 210 can evenly guide light from the light outlet 111.

[0035] In the embodiment of the present invention, the shell 100 is made of polypropylene (PP) material. It is understandable that the polypropylene material has high elasticity and toughness, and can effectively absorb and alleviate the vibration energy generated by the vehicle during driving. Therefore, compared with the shell 100 made of PC or PC+ABS, the shell 100 of this embodiment can reduce the mutual extrusion and wear between the shell 100 and the light guide plate 210, thereby extending the service life of the shell 100 and the light guide plate 210. In addition, since the polypropylene material has low vibration transmission and good sound insulation performance, the shell 100 of this embodiment can effectively reduce the abnormal sound caused by vibration, which helps to improve the passenger's riding experience.

[0036] In the embodiment of the present invention, the light guide plate 210 is snap-fitted to the housing 100, so that the installation and removal process of the light guide plate 210 is simple and quick. The light guide plate 210 and the housing 100 are tightly connected by snap-fitting, which can effectively resist vibration and further reduce the generation of abnormal noise.

[0037] Reference Figure 8 and Fig. 9 As shown, in the embodiment of the present invention, the light emitting assembly 220 is arranged inside the housing 100 and located on one side of the light guide plate 210. Specifically, the light emitting assembly 220 is located on one side of the light guide plate 210 along the length direction of the housing 100. The light emitting assembly 220 includes a light emitting element 222 and a circuit board 221. The light emitting element 222 can emit light to the light guide plate 210, so as to guide the light to the light outlet 111 through the light guide plate 210. In this embodiment, the light guide plate 210 can play a role of guiding light, which can evenly guide the light emitted by the light emitting assembly 220 to the light outlet 111, so that the light emitted from the light outlet 111 can be softer and more uniform, avoiding the glare caused by the concentration of light.

[0038] In the embodiment of the present invention, the light guide plate 210 is made of polymethylmethacrylate (PMMA) material. Among them, PMMA material has the characteristic of high transparency, and the light guide plate 210 made of PMMA material can present a bright and uniform lighting effect, thereby improving the lighting effect of the atmosphere lamp 1000.

[0039] It is understandable that the PMMA-made light guide plate 210 and the PP-made housing 100 have good structural stability when they are tightly connected. Even if they are subjected to large vibrations and impacts, relative displacement and friction are not easy to occur between the light guide plate 210 and the housing 100, thereby reducing the generation of abnormal noise. Specifically, in this embodiment, the light guide plate 210 and the housing 100 are both injection molded parts, that is, the light guide plate 210 and the housing 100 can be respectively processed by injection molding process.

[0040] In the embodiment of the present invention, the housing 100 is provided with a buckle 120, and the buckle 120 is buckled to the light guide plate 210 to limit the light guide plate 210 from being separated from the mounting groove 110 from the light outlet 111. In one example, the light guide plate 210 is provided with a buckle position corresponding to the buckle 120, and the buckle 120 and the buckle position are buckled and connected, so that the light guide plate 210 is fixed in the mounting groove 110.

[0041] Reference Figure 2 , Figure 3 and Figure 4 As shown, in another example, the buckle 120 is connected to the inner wall of the mounting groove 110 and is located at the light outlet 111, and the buckle 120 is integrally formed with the side wall of the housing 100. The buckle 120 protrudes toward the mounting groove 110 and abuts against the end surface of the light guide plate 210 facing away from the housing 100. It can be understood that in this embodiment, the buckles 120 can be provided on both the upper and lower sides of the light outlet 111, and the buckles 120 on the upper and lower sides cooperate to prevent the light guide plate 210 from moving toward the front side of the atmosphere lamp 1000, thereby preventing the light guide plate 210 from being dislocated.

[0042] Reference Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the inner wall of the mounting groove 110 is recessed to form a positioning groove 112, and the side wall of the light guide plate 210 is protruding to form a positioning protrusion 211 that is positioned and matched with the positioning groove 112. When assembling the light guide plate 210, the cooperation between the positioning groove 112 and the positioning protrusion 211 can play a role in preliminary positioning, greatly improving the assembly efficiency and accuracy of the light guide plate 210. It should be noted that in this embodiment, the combination of the positioning groove 112 and the positioning protrusion 211 can be provided in multiple groups, and this embodiment does not limit this.

[0043] It is understandable that the inventors learned through many experiments that when the distance between the inner wall of the mounting groove 110 and the peripheral wall of the light guide plate 210 is too small, the contact surface between the light guide plate 210 and the shell 100 will be too close, increasing the friction between the two in relative motion. In addition, in a vibration environment, the overly close contact between the light guide plate 210 and the shell 100 is relatively more likely to produce abnormal noises; conversely, when the distance between the inner wall of the mounting groove 110 and the peripheral wall of the light guide plate 210 is too large, the light guide plate 210 will not be firmly fixed in the mounting groove 110, causing the light guide plate 210 to easily shake in the mounting groove 110 and collide with the side wall of the mounting groove 110, which will also produce abnormal noises.

[0044] For this purpose, refer to Figure 6 As shown, in the embodiment of the present invention, the distance between the inner wall of the mounting groove 110 and the peripheral wall of the light guide plate 210 is L, satisfying: 0.2mm (millimeter) ≤ L ≤ 0.6mm (millimeter). By precisely controlling the distance between the inner wall of the mounting groove 110 and the peripheral wall of the light guide plate 210, it is ensured that it is neither too tight to cause wear and abnormal noise, nor too loose to cause loose connection and shaking.

[0045] Reference Figure 8 As shown, in the embodiment of the present invention, a receiving groove 150 communicating with the mounting groove 110 is further formed inside the housing 100, and the receiving groove 150 is located on one side of the mounting groove 110 along the length direction of the housing 100, and the housing 100 is provided with a mounting opening 151 communicating with the receiving groove 150. The mounting opening 151 is covered with a shading plate 600 for blocking the light emitted by the light emitting component 220 from leaking from the mounting opening 151. It should be noted that in the present embodiment, the shading plate 600 and the housing 100 can be connected by snap connection, or by fasteners, or by other forms of connection, which is not limited in the present embodiment. During assembly, the light emitting component 220 can be first placed into the receiving groove 150 from the mounting opening 151, and then the shading plate 600 can be covered on the mounting opening 151 and fastened to the housing 100, thereby completing the assembly of the light emitting component 220.

[0046] Reference Figure 5 and Figure 8 As shown, in an embodiment of the present invention, two light-emitting components 220 may be provided. Based on this, two receiving grooves 150 and two shading plates 600 are also provided. The two receiving grooves 150 are respectively arranged on both sides of the installation groove 110. The two light-emitting components 220 are respectively installed in the corresponding receiving grooves 150, and the two shading plates 600 are arranged one by one at the installation openings 151 of the two installation grooves 110.

[0047] Reference Figure 1 and Fig. 9As shown, in the embodiment of the present invention, the light emitting assembly 220 further includes a wire 223 and a terminal 224, wherein the wire 223 is connected to the circuit board 221. The end surface of the housing 100 facing away from the light guide plate 210 is provided with a wire hole (not shown in the figure) for the wire 223 to pass through, and the terminal 224 is provided at the end of the wire 223 and exposed outside the housing 100 for connection with other electrical components or controllers.

[0048] Reference Figure 8 As shown, in the embodiment of the present invention, the end surface of the light guide plate 210 facing the housing 100 is covered with a reflective film 400, which can reflect the light escaping from the edge of the light guide plate 210 back into the light guide plate 210, thereby reducing the loss of light and improving the utilization rate of light. The end surface of the light guide plate 210 facing away from the housing 100 is covered with a uniform light film 500, which can evenly diffuse the light emitted by the light guide plate 210, reduce light spots and shadows, and thus improve the uniformity of lighting.

[0049] Reference Figure 7 and Figure 8 As shown, in the embodiment of the present invention, the atmosphere lamp 1000 further includes a light distribution member 300, which is connected to the housing 100 and covers the light outlet 111, thereby ensuring that the light emitted from the light outlet 111 can be emitted through the light distribution member 300, reducing the possibility of light leakage at the edge of the atmosphere lamp 1000. Specifically, on the projection plane perpendicular to the front-rear direction of the atmosphere lamp 1000, the projection of the housing 100 is located within the projection of the light distribution member 300.

[0050] Reference Figure 8 and Fig.10 As shown, in an embodiment of the present invention, a diaphragm 310 is provided on the side of the light distribution component 300 facing away from the light guide plate 210, and the diaphragm 310 covers the end face of the light distribution component 300 facing away from the light guide plate 210. Among them, the diaphragm 310 includes a light-transmitting area (not shown in the figure) and a light-shielding area (not shown in the figure). It can be understood that the light-transmitting area allows light to pass through, while the light-shielding area can block light. Based on this, in this embodiment, when the light emitted from the light outlet 111 is irradiated on the light-transmitting area and the light-shielding area, the light can only pass through the light-transmitting area, and the light-transmitting area can be pre-set to a specific pattern. Therefore, when the light emitted from the light outlet 111 passes through the diaphragm 310, it can project the expected pattern or light and shadow effect, which greatly enhances the aesthetics and decorativeness of the atmosphere lamp 1000.

[0051] It can be understood that by engraving a light-transmitting area with a fine and complex pattern on the diaphragm 310, without increasing the cost and without occupying the internal space of the shell 100, the atmosphere light 1000 of this embodiment can show a more complex pattern effect, compared with the atmosphere light 1000 that can only present a point-like or strip-like lighting effect, and enrich the lighting form of the atmosphere light 1000. When used in vehicle door panels, it can also meet the use requirements of different application scenarios and different interior styles, expand the application scenarios of the atmosphere light 1000, enhance the aesthetics and decorativeness of the atmosphere light 1000, and provide passengers with richer visual effects.

[0052] In one example, the light distribution component 300 is detachably connected to the housing 100. Specifically, the light distribution component 300 and the housing 100 may be connected by fasteners, or by buckles 120, or by other types of connection methods, which are not limited in this embodiment. It is understandable that the driver and passengers can choose or design a unique lighting effect and pattern of the atmosphere lamp 1000 according to their own preferences and needs, and customize the corresponding light distribution component 300 accordingly. When in use, the lighting form of the atmosphere lamp 1000 can be easily changed by simply replacing different light distribution components 300, thereby realizing the personalization and customization of the lighting effect of the atmosphere lamp 1000, which greatly meets the personalized needs of users.

[0053] In the embodiment of the present invention, the diaphragm 310 is formed on the end surface of the light distribution component 300 facing away from the light guide plate 210 by the IMD process (In-Mold Decoration). It can be understood that the IMD process can ensure that the pattern on the diaphragm 310 is transferred to the light distribution component 300 in a high-precision manner, and the clarity, details and colors of the pattern can be well preserved, thereby improving the visual effect and aesthetics of the light distribution component 300. In addition, since the diaphragm 310 is embedded in the plastic part, the pattern part and the light distribution component 300 become a whole, which means that the pattern is not easy to fall off, fade or wear, and can maintain its original appearance for a long time, thereby improving the durability and wear resistance of the pattern.

[0054] Reference Fig.11 and Fig.12 As shown, in the embodiment of the present invention, a connecting arm 320 is formed at one end of the light distribution member 300 facing the housing 100, and the connecting arm 320 extends toward the rear side. The side wall of the housing 100 is provided with a first lug 130 corresponding to the connecting arm 320, and specifically, the first lug 130 is formed on the upper side or the lower side of the housing 100. The first lug 130 is provided with a through hole 131, and the through hole 131 penetrates the first lug 130 in the front-to-back direction. Based on this, the connecting arm 320 is penetrated through the through hole 131 and connected to the first lug 130, thereby realizing the connection between the light distribution member 300 and the housing 100.

[0055] It is understandable that when the light distribution member 300 covers the light outlet 111, part of the light will still leak from the upper and lower edges of the light outlet 111, affecting the lighting effect of the atmosphere lamp 1000. Fig.10 and Fig.12 As shown, in the embodiment of the present invention, the connecting arm 320 is arranged to extend backward along the side wall of the housing 100. It should be noted that one end of the connecting arm 320 is connected to the end surface of the light distribution member 300 facing the housing 100, and the connecting arm 320 can be integrally formed with the light distribution member 300. The connecting arm 320 is located at the position of the side wall of the housing 100, and the connecting arm 320 is a light-proof structure, thereby blocking light from passing through the gap between the light distribution member 300 and the housing 100.

[0056] Reference Fig.10 As shown, the gap between the light distribution component 300 and the housing 100 is a first gap 700, and the gap between the connecting arm 320 and the housing 100 is a second gap 800. It should be noted that in the embodiment of the present invention, the connecting arm 320 can block the light passing through the first gap 700 from escaping upward, and the first lug 130 is formed on the side wall of the housing 100, so the first lug 130 can block the light passing through the second gap 800 from escaping backward, thereby ensuring that the light propagates in a predetermined direction (light guide plate 210-light outlet 111-light distribution component 300-diaphragm 310), reducing unnecessary scattering inside the atmosphere lamp 1000, enhancing the accuracy of light control, and effectively reducing the light leakage phenomenon in other areas of the atmosphere lamp 1000 except the light distribution component 300, thereby greatly reducing the negative impact of unexpected light on the overall lighting effect. Reference Fig.10 As shown, in an embodiment of the present invention, the light distribution component 300 includes a body 330 and a flange portion 340, wherein two flange portions 340 are provided, and the two flange portions 340 are formed at both ends of the body 330 along the width direction of the housing 100 and protrude toward the rear side. In this embodiment, the body 330 and the light guide plate 210 are arranged opposite to each other along the front-to-back direction of the housing 100. In one example, the light guide plate 210 and the body 330 are both arranged to be tilted downward. In one example, the diaphragm 310 is formed on the end surface of the body 330 that is away from the housing 100. In another example, the body 330 and the flange portion 340 are integrally formed, and the diaphragm 310 is formed on the end surfaces of the body 330 and the flange portion 340 that are away from the housing 100.

[0057] Continue to refer to Fig.10As shown, in the embodiment of the present invention, the connecting arm 320 is connected to the end surface of the body 330 facing the housing 100, and the connecting arm 320 is provided with a light shielding structure 321, which is provided at one end of the connecting arm 320 close to the body 330. In one example, the connecting arm 320 and the light shielding structure 321 are integrally formed. The light shielding structure 321 is bent along the end surface of the body 330 facing the housing 100 toward the flange portion 340. It can be understood that Fig.10 Taking the connecting arm 320 located in the upper half as an example, the size of the main body 330 in the width direction of the shell 100 is larger than the size of the shell 100 in its width direction. In order to prevent the part of the main body 330 that exceeds the shell 100 from leaking light backwards, in this embodiment, the shading structure 321 extends along the flange portion 340 facing the upper side of the rear end of the main body 330 and is connected to the flange portion 340, effectively blocking the light from being emitted from the rear end of the main body 330 to the rear side, thereby ensuring precise control of the light.

[0058] It is understandable that, referring to Fig.10 As shown, in the embodiment of the present invention, the upper side and the lower side of the housing 100 may be provided with a first lug 130, and correspondingly, the rear side of the body 330 is provided with two connecting arms 320 corresponding to the two first lugs 130. In this embodiment, the light guide plate 210 and the body 330 are both arranged to tilt downward, wherein the light shielding structure 321 of the connecting arm 320 connected to the upper half is tilted upward toward the front side, and the light shielding structure 321 of the connecting arm 320 connected to the lower half is tilted downward toward the rear side.

[0059] It is understandable that the inventors have learned from repeated experiments that when the thickness of the body 330 is too thick, the light will be obstructed too much when propagating inside, affecting the uniformity and brightness of the light, and the overly thick body 330 will occupy more installation space. When the thickness of the body 330 is too thin, the overall structural strength of the light distribution component 300 will be too low. For this reason, refer to Fig.13 As shown, in the embodiment of the present invention, along the front-to-back direction of the shell 100, the thickness range of the main body 330 is W, satisfying: 2.5mm (millimeter) ≤ W ≤ 3.5mm (millimeter). On the premise that the light distribution component 300 has sufficient structural strength, it is ensured that the light passing through the light distribution component 300 can achieve the expected illumination uniformity and brightness standards.

[0060] Reference Figure 6 As shown, in the embodiment of the present invention, the through hole 131 is a square hole. Specifically, the connecting arm 320 and at least one side of the inner wall of the through hole 131 are arranged at intervals. It can be understood that, referring to Fig.10As shown, in this embodiment, along the width direction of the housing 100, the width of the connecting arm 320 is smaller than the width of the through hole 131; and / or along the length direction of the housing 100, the length of the connecting arm 320 is smaller than the length of the through hole 131, so when the connecting arm 320 is inserted into the through hole 131, there is a gap between the peripheral wall of the connecting arm 320 and the inner wall of the through hole 131. Based on this, the connecting arm 320 can be welded to the inner wall of the through hole 131, so as to realize the welding connection between the connecting arm 320 and the first lug 130.

[0061] It should be noted that after welding is completed, the space between the connecting arm 320 and the inner wall of the through hole 131 will be filled with solder to form an additional light-shielding barrier, which can also play a light-shielding role and further block the light passing through the second gap 800 from escaping backward.

[0062] Reference Figure 5 As shown, in the embodiment of the present invention, the housing 100 is provided with a plurality of first lugs 130, and the plurality of first lugs 130 are arranged at intervals along the circumference of the housing 100. Correspondingly, the light distribution member 300 is provided with a plurality of connecting arms 320, and the plurality of connecting arms 320 are connected to the plurality of first lugs 130 in a one-to-one correspondence. Through the one-to-one correspondence between the plurality of first lugs 130 and the plurality of connecting arms 320, a plurality of connection points can be formed, thereby enhancing the connection stability between the housing 100 and the light distribution member 300, and ensuring the overall structural stability of the atmosphere lamp 1000. It should be noted that, in the present embodiment, the number of the first lugs 130 provided on the upper side and the first lugs 130 provided on the lower side of the housing 100 may be the same or different.

[0063] Reference Figure 6 and Fig.12 As shown, in the embodiment of the present invention, the side wall of the housing 100 along the length direction and the side wall along the width direction are respectively provided with a second lug 140, the second lug 140 is formed with a positioning hole 141, and the light distribution member 300 is provided with a positioning portion 350 penetrating the positioning hole 141. During assembly, the positioning portion 350 can be first aligned with the corresponding positioning hole 141 and inserted, thereby achieving preliminary positioning of the light distribution member 300, and then the connecting arm 320 is inserted into the through hole 131 to complete the assembly of the light distribution member 300, thereby improving the assembly efficiency and assembly accuracy of the light distribution member 300.

[0064] In an embodiment of the present invention, the transmittance range of the light distribution component 300 is greater than or equal to 65%. The high-transmittance light distribution component 300 can not only provide a clearer and brighter visual effect, but also ensure that enough light is effectively utilized, reducing the loss of light, thereby improving the lighting efficiency of the atmosphere lamp 1000 and reducing the energy consumption of the atmosphere lamp 1000.

[0065] In the embodiment of the present invention, the haze range of the light distribution component 300 is greater than or equal to 96%, and the illumination uniformity range of the light distribution component 300 is greater than or equal to 60%. It is understandable that when the haze range of the light distribution component 300 is greater than or equal to 96%, light will be scattered in the process of penetrating the light distribution component 300, so that the atmosphere lamp 1000 can have a soft and uniform lighting effect. At the same time, when the illumination uniformity of the light distribution component 300 is greater than or equal to 60%, the light and dark differences and shadow areas of the atmosphere lamp 1000 can be reduced, thereby improving the lighting quality of the atmosphere lamp 1000 and optimizing the visual effect of the atmosphere lamp 1000.

[0066] In the embodiment of the present invention, the light distribution component 300 is made of PC material (Polycarbonate). It can be understood that, firstly, the polycarbonate material has high strength and toughness, and the light distribution component 300 made of polycarbonate can withstand greater external impact and pressure, ensuring its stability and reliability in long-term use. Secondly, the polycarbonate material has good light transmittance, and the light distribution component 300 made of polycarbonate can reduce light loss, thereby improving the lighting efficiency of the atmosphere lamp 1000.

[0067] The embodiment of the present invention further proposes a vehicle door panel, including a door body and the atmosphere light 1000 of the above embodiment, wherein the atmosphere light 1000 is installed on the door body.
