Description

Technical Field

[0001] This application relates to the field of transportation technologies, and particularly to a vehicle taillight and a vehicle. Background Art

[0002] The vehicle rear door (also known as the tailgate / trunk lid), as a core component for enclosing the storage compartment, its structural design directly affects the convenience of users' travel. In the prior art, some vehicle taillights are installed on the vehicle rear door. At this time, the size of the vehicle taillight is an important factor affecting the thickness of the vehicle rear door. However, with the diversification of vehicle taillight designs (such as starry sky, snowflake and other shapes), the structure of the vehicle taillight has become more and more complex, and the complex vehicle taillight occupies a larger space on the vehicle rear door, which will inevitably thicken the thickness of the vehicle rear door and encroach on the storage space of the trunk, affecting the user's purchase and usage experience.

[0008] The light emitted by the light-emitting unit passes through the light-transmitting area and is transmitted to the mask. Part of the light is reflected by the mask to the reflective layer and then reflected by the reflective layer to the mask.

[0009] In one embodiment, a light-shielding layer is provided on one side of the inner decorative panel in the vehicle length direction and facing the mask. The light-shielding layer forms the light-transmitting area and the light-shielding area through a surface treatment process, and a reflection layer is provided on the light-shielding layer on one side of the inner decorative panel in the vehicle length direction and facing the mask.

[0010] In one embodiment, the surface treatment process includes any one of laser engraving process, sandblasting process, etching process, and surface pattern transfer process.

[0011] In one embodiment, the light-emitting unit includes a first light-emitting unit, a second light-emitting unit, a third light-emitting unit, and a fourth light-emitting unit. The first light-emitting unit, the second light-emitting unit, the third light-emitting unit, and the fourth light-emitting unit are all installed on the second bracket and arranged in sequence from top to bottom along the vehicle height direction;

[0012] Wherein, the first light-emitting unit and the fourth light-emitting unit are covered by the inner decorative panel, so that at least part of the light emitted by the first light-emitting unit and the fourth light-emitting unit passes through the light-transmitting area and is transmitted to the mask; the second light-emitting unit and the third light-emitting unit both penetrate through the inner decorative panel, so that the light emitted by the second light-emitting unit and the third light-emitting unit can be directly projected onto the mask respectively.

[0013] In one embodiment, the first light-emitting unit and the fourth light-emitting unit are both configured as position lights, the second light-emitting unit is configured as a brake light, and the third light-emitting unit is configured as a fog light.

[0014] In one embodiment, the first light-emitting module includes a first bracket, a first light source, and a first thick-wall lens. The first bracket is installed on the housing, the first light source is installed on the first bracket or the housing, the first thick-wall lens is installed on the first bracket, and the light emitted by the first light source passes through the first thick-wall lens and the mask in sequence and is emitted.

[0015] In one embodiment, the first light-emitting module further includes a second light source, a first reflector bowl, and a first inner lens. The second light source, the first reflector bowl, and the first inner lens are all installed on the first bracket;

[0016] Wherein, the number of the second light sources is set to be multiple and arranged along the vehicle width direction. The first inner lens is provided with a pattern structure on at least one of the two surfaces in the vehicle length direction.

[0020] The present application also provides the following technical solutions:

[0021] A vehicle includes the vehicle tail lamp in any of the above embodiments.

[0022] Compared with the prior art, in the vehicle tail lamp and the vehicle, by providing a light-transmitting area, a light-shielding area, and a reflective layer on the inner decorative panel, the light emitted by the light-emitting unit passes through the light-transmitting area and is transmitted to the face mask, and part of the light is reflected by the face mask to the reflective layer and then reflected by the reflective layer to the face mask. In this way, multiple light points will be formed on the face mask and form a visual effect of a starry sky (starlight). Thus, by using the refraction and reflection of the reflective layer on the light, a starlight effect can be formed while reducing the use of light sources, thereby simplifying the structure of the vehicle tail lamp, reducing the overall size of the vehicle tail lamp, and further reducing the thickness of the vehicle back door.

Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0042] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions used in the specification of the present application are only for illustrative purposes and do not represent the only implementation manner.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] In the present application, unless otherwise clearly specified and limited, the first feature can be in direct contact with the second feature "on" or "under" the second feature, or the first feature and the second feature can be in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or it only means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below", and "beneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or it only means that the first feature has a lower horizontal height than the second feature.

[0045] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific implementation manners and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0046] As Figure 1As shown, the present application provides a vehicle taillight 100, which is mainly used to be installed on a back door 200 of a car. Here, the back door 200 is also called the tail door, trunk door or luggage compartment door of the vehicle.

[0047] Specifically, please refer to Figure 2 The vehicle taillight 100 includes a housing 10, a mask 20 and a light module 30. The housing 10 is used to be installed on the back door 200. The mask 20 is installed on the housing 10 and forms an installation space 11 with the housing 10. The light module 30 is accommodated in the installation space 11 and installed on the housing 10. The light emitted by the light module 30 is transmitted through the mask 20 as a signal indication. Generally speaking, the functions of the vehicle taillight 100 include position prompts, brake prompts, turn prompts, reversing prompts, and fog lamp functions. Therefore, the light module 30 can realize the functions of position, braking, turning, reversing, and fog lamps through different lights or light combinations.

[0048] Here, the mask 20 and the housing 10 can be fixed by welding, snapping, etc. In addition, a sealing ring is provided between the mask 20 and the housing 10 to ensure the sealing of the installation space 11 through the sealing ring.

[0049] It should be explained that since the vehicle taillight 100 is installed on the back door 200, a corresponding space needs to be reserved on the back door 200. Therefore, the size of the vehicle taillight 100 in the vehicle length direction x also determines the thickness of the back door 200 in the vehicle length direction x, and the thickness of the back door 200 also affects the vehicle trunk storage space, thereby affecting the convenience of user travel. In order to achieve this, the present application reduces the thickness of the back door 200 by compressing the size of the vehicle taillight 100 in the vehicle length direction x, so as to maximize the storage space of the vehicle trunk and make it more convenient for users to travel.

[0050] Specifically, if Figure 3 and Figure 4 As shown, the light-emitting module 30 includes a first light-emitting module 31, a second light-emitting module 32 and a third light-emitting module 40. Along the height direction z of the vehicle, the first light-emitting module 31, the second light-emitting module 32 and the third light-emitting module 40 are arranged in sequence, and the first light-emitting module 31 is relatively located above the second light-emitting module 32, and the third light-emitting module 40 is located between the first light-emitting module 31 and the second light-emitting module 32. Here, the first light-emitting module 31 is mainly used for position and brake prompt functions, the second light-emitting module 32 is mainly used for position, reversing, fog lamp and other functions, and the third light-emitting module 40 is mainly used for steering and position prompt functions. Of course, it can be understood that the function and position settings of each module can be set according to actual needs.

[0051] For further information, please refer toFigure 1 and Figure 4 The housing 10 is arranged in a ring shape. The first light-emitting module 31 and the second light-emitting module 32 extend along the vehicle width direction y. There are two third light-emitting modules 40, and the two third light-emitting modules 40 are arranged on both sides of the housing 10 in the vehicle width direction y. In this way, the first light-emitting module 31, the second light-emitting module 32, and the third light-emitting module 40 together form a ring structure. That is, the vehicle taillight 100 is an overall through-type taillight.

[0052] In one embodiment, as Figure 5 and Figure 6 shown, the first light-emitting module 31 includes a first bracket 311, a first light source 312, and a first thick-wall lens 313. The first bracket 311 is mounted on the housing 10, the first light source 312 is mounted on the first bracket 311 or the housing 10, and the first thick-wall lens 313 is mounted on the first bracket 311. The light emitted by the first light source 312 passes through the first thick-wall lens 313 and the mask 20 in sequence and then emits out. Here, the light formed by the first light source 312 constitutes a brake light, that is, it forms a brake reminder when the vehicle brakes.

[0053] Furthermore, please continue to refer to Figure 6 , the first light-emitting module 31 further includes a second light source 314, a first reflector bowl 315, and a first inner lens 316. The second light source 314, the first reflector bowl 315, and the first inner lens 316 are all mounted on the first bracket 311. Among them, the second light source 314 extends along the vehicle width direction. The first inner lens 316 is provided with a first pattern structure 3161 on at least one of the two surfaces in the vehicle length direction x. The light emitted by the second light source 314 is reflected by the first reflector bowl 315 and then passes through the first inner lens 316 and the mask 20 in sequence and emits out. And under the action of the pattern structure 3161 on the surface of the first inner lens 316, a display effect with corresponding patterns will be formed. Here, the light emitted by the second light source 314 constitutes one or a combination of two of a brake light and a position light. It can be understood that in this application, the functions of the brake light and the position light can be realized through the first reflector bowl 315 and the first inner lens 316. Compared with the traditional long and thick-wall optical components, the structure is simpler and the layout is more compact, so as to effectively reduce the size of the vehicle taillight 100 in the vehicle length direction x at a local position. And by providing the first pattern structure 3161 on the surface of the first inner lens 316, the light emitted by the second light source 314 forms a visual effect with corresponding patterns, and the recognition degree is also higher.

[0054] Preferably, the number of the second light sources 314 may be multiple, and the multiple second light sources 314 are arranged at intervals along the width direction y of the vehicle. For example, the number of the second light sources 314 is set to twenty, thirty or forty, and the specific number can be set according to the actual situation. At the same time, the brake lights and position lights may be arranged alternately in the width direction y of the vehicle, or multiple relatively independent areas may be set in the width direction y of the vehicle, with one area arranged with brake lights and one area arranged with position lights. Here, the specific arrangement of the brake lights and position lights can be set according to the actual situation.

[0055] In this embodiment, one surface of the first inner lens 316 in the vehicle length direction x is set as an irregular surface and forms a bright diamond pattern, and at the same time, combined with the arrangement of the second light sources 314 in the vehicle width direction y. So that the light passes through the transmission of the first inner lens 316, and a bright diamond effect and a gorgeous effect will be formed in the width direction y of the vehicle, effectively improving the recognition. That is to say, the bright diamond effect and the gorgeous effect can be realized through the structure of the first inner lens 316, and its structure is simpler and more conducive to the compact setting of the local position space.

[0056] Here, the first pattern structure 3161 may also be a crystal pattern, a star pattern, a snowflake pattern, a star river pattern, etc. Of course, it is not limited to this, and the pattern structure can be selected according to the corresponding setting requirements.

[0057] Preferably, both surfaces of the first inner lens 316 in the vehicle length direction x are set as irregular surfaces, so that bright diamond patterns are formed on both surfaces, thereby improving the bright diamond effect and the gorgeous effect.

[0058] As Figure 5 and Figure 7 As shown, the second light-emitting module 32 includes a second reflecting bowl 321, a third light source 322 and a second inner lens 323. The second reflecting bowl 321 is installed on the housing 10, the third light source 322 is installed in the second reflecting bowl 321, and the second inner lens 323 is installed on the second reflecting bowl 321. The light emitted by the third light source 322 is reflected by the second reflecting bowl 321, and then passes through the second inner lens 323 and the mask 20 in sequence and is emitted. Here, the light emitted by the third light source 322 constitutes one or a combination of two of the turn signal lights and the position lights. It can be understood that the turn signal light and position light functions can be realized by the second reflecting bowl 321 and the second inner lens 323 in this application. Compared with the traditional optical components with long and thick walls, the structure is simpler and the arrangement is more compact, so as to effectively reduce the size of the vehicle tail lamp 100 in the vehicle length direction x at the local position.

[0059] Preferably, the number of the third light sources 322 may be multiple. The multiple third light sources 322 are arranged at intervals along the width direction y of the vehicle and extend to the positions of the corresponding third light-emitting modules 40. For example, the number of the third light sources 322 is set to twenty, thirty, or forty, and the specific number can be set according to the actual situation. At the same time, the turn signals and position lights may be arranged alternately in the width direction y of the vehicle, or multiple relatively independent areas may be set in the width direction y of the vehicle. One area is arranged with brake lights, and one area is arranged with position lights.

[0060] In this embodiment, in the width direction y of the vehicle, the middle region of the housing 10 is set as a position light, and the two side regions are arranged as a combination of turn signals and position lights. In this way, when the vehicle turns, it can create a flowing water effect that spreads from the middle position of the housing 10 to both sides.

[0061] Further, a second pattern structure 3231 is provided on one surface of the second inner lens 323 in the vehicle length direction x, so that the light emitted by the third light sources 322 forms a visual effect of corresponding patterns, effectively improving the recognition rate.

[0062] In this embodiment, one surface of the second inner lens 323 in the vehicle length direction x is set as an irregular surface and forms a bright diamond pattern. In this way, under the transmission action of the second inner lens 323, combined with the arrangement of the third light sources 322 in the width direction of the vehicle, a bright diamond effect and a gorgeous effect can be formed in the width direction y of the vehicle, improving the recognition rate. That is, the bright diamond effect and the gorgeous effect can be realized through the structure of the second inner lens 323, and its structure is simpler, which is more conducive to the compact setting of the local position space.

[0063] Here, the second pattern structure 3231 may also be a crystal pattern, a star pattern, a snowflake pattern, a star river pattern, etc. Of course, it is not limited to this, and the pattern structure can be selected according to the corresponding setting requirements.

[0064] Preferably, both surfaces of the second inner lens 323 in the vehicle length direction x are set as irregular surfaces, so that bright diamond patterns are formed on both surfaces, thereby improving the bright diamond effect and the gorgeous effect.

[0065] Such as Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 And Figure 11As shown in the figure, the third light-emitting module 40 includes a second bracket 41, a light-emitting unit 42, and an inner decorative panel 43. The second bracket 41 is installed on the housing 10, the light-emitting unit 42 is installed on the second bracket 41, the inner decorative panel 43 covers at least a part of the light-emitting unit 42 in the vehicle length direction x, and the inner decorative panel 43 has a light-transmitting area 431 and a light-shielding area 432 on the side facing the mask 20 in the vehicle length direction x. The inner decorative panel 43 is also provided with a reflective layer 433 on the side facing the mask 20 in the vehicle length direction x; the light emitted by the light-emitting unit 42 is transmitted through the light-transmitting area 431 to the mask 20, and part of the light is reflected by the mask 20 to the reflective layer 433, and then reflected by the reflective layer 433 to the mask 20 (refer to Figure 11 ). In this way, a plurality of light points will be formed on the mask 20, and the plurality of points will gather to form the visual effect of a starry sky (starlight). That is to say, the present application uses the refraction and reflection of the reflective layer 433 on the light to form a starry sky effect while reducing the use of light sources, thereby simplifying the overall structure of the vehicle tail lamp 100, reducing the overall size of the vehicle tail lamp 100, and further reducing the thickness of the vehicle back door 200, so as to reduce the encroachment of the vehicle back door 200 on the storage space of the trunk and improve the user experience.

[0066] As Figure 8 shown in the figure, the light-emitting unit 42 includes a first light-emitting unit 421, a second light-emitting unit 422, a third light-emitting unit 423, and a fourth light-emitting unit 424. The first light-emitting unit 421, the second light-emitting unit 422, the third light-emitting unit 423, and the fourth light-emitting unit 424 are all installed on the second bracket 41 and are arranged in sequence from top to bottom along the vehicle height direction z. The inner decorative panel 43 covers the first light-emitting unit 421 and the fourth light-emitting unit 424. In this way, the light emitted by the first light-emitting unit 421 and the fourth light-emitting unit 424 needs to be transmitted through the inner decorative panel 43 and then irradiate on the mask 20. Part of the second light-emitting unit 422 and the third light-emitting unit 423 penetrates the inner decorative panel 43, so that the second light-emitting unit 422 and the third light-emitting unit 423 directly shoot onto the mask 20, thus forming stronger light.

[0067] Preferably, the first light-emitting unit 421 is mainly used for position indication, the second light-emitting unit 422 is mainly used for reverse indication, the third light-emitting unit 423 is mainly used for fog lamps, and the fourth light-emitting unit 424 is also used for position indication. Of course, it can be understood that the functions and position settings of each module can be set according to actual needs.

[0068] Please continue to refer to Figure 8, the first light-emitting unit 421 includes a first circuit board 4211 and a fourth light source 4212. The first circuit board 4211 is installed on the second bracket 41, and the fourth light source 4212 is installed on the first circuit board 4211. The light emitted by the fourth light source 4212 is emitted through the inner decorative panel 43, thereby serving as a position reminder.

[0069] Further, a plurality of fourth light sources 4212 are provided, and the plurality of fourth light sources 4212 are arranged on the first circuit board 4211. At the same time, the brightness of some of the fourth light sources 4212 can be relatively bright, and the brightness of some of the fourth light sources 4212 can be relatively dim, so as to form a bright and dark effect. Here, the number of the fourth light sources 4212 can be ten, twenty, thirty, etc.

[0070] It should be explained that the bright and dark effect of the fourth light source 4212 can be controlled by the circuit itself or can be achieved through the setting of the light-transmitting area 431. Here, by controlling the current magnitude of each light source, the control of the bright and dark effect of each fourth light source 4212 can be achieved. By changing the thickness of each light-transmitting area 431 or changing its light transmittance, the control of the bright and dark effect of each fourth light source 4212 can also be achieved.

[0071] Please continue to refer to Figure 8 , the second light-emitting unit 422 includes a fifth light source 4221 and a third thick-wall lens 4222. The fifth light source 4221 is installed on the second bracket 41 or the housing 10, and the third thick-wall lens 4222 is installed on the second bracket 41 and penetrates through the inner decorative panel 43. The light emitted by the fifth light source 4221 is emitted out successively through the third thick-wall lens 4222 and the mask 20. Here, the light emitted by the fifth light source 4221 constitutes a reverse light, that is, it forms a reverse reminder when the vehicle is reversing.

[0072] The third light-emitting unit 423 includes a sixth light source 4231 and a fourth thick-wall lens 4232. The sixth light source 4231 is installed on the second bracket 41 or the housing 10, and the fourth thick-wall lens 4232 is installed on the second bracket 41 and penetrates through the inner decorative panel 43. The light emitted by the sixth light source 4231 is emitted out successively through the fourth thick-wall lens 4232 and the mask 20. Here, the light emitted by the sixth light source 4231 constitutes a fog light, that is, it forms a reminder when the vehicle is in a foggy environment.

[0073] Please refer to Figure 8 , the fourth light-emitting unit 424 includes a second circuit board 4241 and a seventh light source 4242. The second circuit board 4241 is installed on the second bracket 41, and the seventh light source 4242 is installed on the second circuit board 4241. The light emitted by the seventh light source 4242 is emitted through the inner decorative panel 43, and it also serves as a position reminder.

[0074] Preferably, a plurality of seventh light sources 4242 are provided, and the plurality of seventh light sources 4242 are provided on the first circuit board 4211. At the same time, the brightness of some of the seventh light sources 4242 can be relatively bright, and the brightness of some of the seventh light sources 4242 can be relatively dim, so that a bright and dark effect can be formed. Here, the number of the seventh light sources 4242 can be ten, twenty, thirty, etc. The brightness control of the seventh light source 4242 can refer to the control of the fourth light source 4212, which will not be elaborated here.

[0075] As Figure 8 , Figure 9 , Figure 10 shown, the inner decorative panel 43 can be a light-transmitting plate such as a polymethyl methacrylate (PMMA) plate, a polystyrene (PS) plate, or a polycarbonate (PC) plate.

[0076] On one side of the inner decorative panel 43 in the vehicle length direction x and facing the mask 20, a light-shielding layer 434 is provided. The light-shielding layer 434 forms the above-mentioned light-transmitting area 43 (such as Figure 7 the dot area on the surface of the inner decorative panel 43 in Figure 7 ) and the light-shielding area 432 (such as Figure 7 the area outside the dot area on the surface of the inner decorative panel 43 in Figure 7 ) through a surface treatment process. And on the light-shielding layer 434 on one side of the inner decorative panel 43 in the vehicle length direction x and facing the mask 20, the above-mentioned reflective layer 433 is provided.

[0077] Specifically, the inner decorative panel 43 has a first side surface 435 and a second side surface 436 arranged opposite to each other in the vehicle length direction x. In the vehicle length direction x, the first side surface 435 faces the first light-emitting unit 421, and the second side surface 436 faces the mask 20. A light-shielding layer 434 is provided on the second side surface 436, and the light-shielding layer 434 is engraved by a laser engraving process to remove the local light-shielding part, so that the entire side surface of the inner decorative panel 43 in the vehicle length direction x forms a light-transmitting area 431 with a local light-transmitting effect and a light-shielding area 432 with a light-shielding effect for the remaining part. At the same time, a reflective layer 433 is coated on the light-shielding layer 434 on the second side surface 436, so that the second side surface 436 has a reflective function at the same time (as Figure 10 shown). Here, the reflective layer 433 can be a high-brightness paint layer, an aluminum film layer, etc. The light-shielding layer 434 can be a paint layer, a PA silver glue coating (silver powder added to acrylic resin), etc.

[0078] Of course, in another embodiment, the light-shielding layer 434 itself can be provided with a reflective function, so that there is no need to separately provide an additional emission layer 433. For example, the light-shielding layer 434 is set as a high-brightness paint layer, an aluminum film layer, etc., so that the light-shielding layer 434 not only has a light-shielding effect but also has a reflective function.

[0079] Optionally, the surface treatment process includes any one of laser engraving process, sandblasting process, etching process, and surface pattern transfer process. In this embodiment, the surface treatment process is set as the laser engraving process.

[0080] Refer to Figure 2 , Figure 3 and Figure 4 , the third light-emitting module 40 further includes a fifth light-emitting unit 425. The fifth light-emitting unit 425 is disposed on the housing 10 along the width direction y of the vehicle, and the position of the fifth light-emitting unit 425 is adjacent to the second light-emitting unit 422 or the third light-emitting unit 423. The second light-emitting unit 422 is configured as a position light or a turning light. Thus, combined with the position lights of the first light-emitting module 31 and the second light-emitting module 32, the vehicle tail light 100 can form a ring-shaped position prompt.

[0081] Specifically, there are two fifth light-emitting units 425, which are arranged in one-to-one correspondence with the two second light-emitting units 422. Along the width direction y of the vehicle, one fifth light-emitting unit 425 is disposed on each side of the housing 10. That is to say, the two fifth light-emitting units 425 are arranged on both sides along the width direction y of the vehicle.

[0082] Furthermore, the structure of the fifth light-emitting unit 425 is the same as that of the first light-emitting module 31 or the second light-emitting module 32. The slight difference lies in their arrangement forms. Here, the fifth light-emitting unit 425 extends along the height direction z of the vehicle, and the first light-emitting module 31 or the second light-emitting module 32 extends along the width direction y of the vehicle.

[0083] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0084] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
