Description

Technical Field

[0001] The utility model belongs to the field of automobile parts, and particularly relates to a high-mounted brake light. Background Art

[0002] The high-mounted brake light is an auxiliary light of the brake light, also known as the third brake light. It is generally installed on the upper part of the vehicle tail so that the vehicle behind can detect the vehicle in front in time and apply the brake to prevent rear-end collisions. At present, most of the high-mounted brake lights on cars adopt the mode of light emission through a reflector or a Fresnel lens. In this way of lighting and light emission, a granular feeling can be clearly seen visually, and the aesthetics is poor. Some high-mounted brake lights adopt the mode of direct emission of multiple groups of LED lights plus light emission of wall thickness parts. Although the sense of high-class light emission is good, the LED consumption is large, the energy consumption is high, and the cost is relatively high; especially for ultra-long high-mounted brake lights with a length exceeding 800 mm, more groups of LED lights need to be arranged to ensure the uniformity of light emission. There are also some high-mounted brake lights that adopt the light-emitting form with the end light guide as the light-emitting surface. Although the structure is relatively simple, it has the common problem of hard light guides, that is, the fine vertical bar light-emitting effect, and the light-emitting uniformity effect needs to be improved.

[0003] Therefore, it is necessary to develop and design a new high-mounted brake light to ensure the overall light-emitting uniformity of the high-mounted brake light, reflect the high-class sense of light emission of the wall thickness part, and improve the aesthetics of the whole vehicle on the premise of relatively low cost. Content of the Utility Model

[0007] Further, the lamp housing assembly includes a lamp housing body and a mask fixedly connected to the lamp housing body, and the mask and the lamp housing body enclose to form the receiving cavity.

[0008] Further, the face mask includes a transparent layer and an opaque layer arranged in sequence from outside to inside. The opaque layer is provided with light-transmitting holes extending along its own length direction, and the part of the transparent layer corresponding to the light-transmitting holes constitutes the light-transmitting part.

Specific embodiments

[0023] The following specific examples illustrate the embodiments of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that the drawings provided in the following embodiments are only used to illustrate the basic concept of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0024] Please refer to Figures 1-4 , in this embodiment, a high-mounted brake lamp is disclosed, including: a lamp housing assembly 1 in a strip shape, the lamp housing assembly 1 having a light-transmitting part 1a and an accommodation cavity 1b arranged along the length direction of the lamp housing assembly 1; a light-emitting assembly 2, arranged in the accommodation cavity 1b for emitting light towards the light-transmitting part 1a; it can be understood that the strip shape of the lamp housing assembly 1 here helps to improve its visibility and functionality, and is also suitable for its spatial arrangement and installation on the vehicle. The arranged accommodation cavity 1b ensures the sealing of the light-emitting assembly 2 installed therein and plays a protective role. The light bar that meets the regulations is projected through the arranged light-transmitting part 1a. This part of the structure is similar to that of the traditional high-mounted brake lamp and will not be elaborated here;

[0025] The light-emitting assembly 2 comprises two groups of light emitters 201 respectively arranged at the two ends of the accommodating cavity 1b, a light guide 202 arranged between the two groups of light emitters 201, and a light distribution mirror 203 arranged between the light guide 202 and the light-transmitting portion 1a. The light distribution mirror 203 is provided with a light distribution portion 203a for making the light uniform on the side close to the light-transmitting portion 1a. It can be understood that the light emitted by the light emitter 201 is directed toward the light guide 202. Usually, the center line of the lamp bead of the light emitter 201 is aligned with the center line of the light guide 202. The light guide 202 is a light guide extending along the length of the lamp housing assembly 1. The light guide strips are arranged in the direction of the light guide 202, and the light guide 202 is designed with many light guide teeth, which destroys the complete reflection inside the light guide 202, so that the light emitted by the light emitter 201 can be diverged and uniformed for the first time. Here, the first light uniformization treatment of the light guide 202 is similar to the structure of the existing end-type light guide high-mounted brake lamp, and will not be repeated here; here, the light emitter 201 is preferably an energy-saving LED lamp; the light distribution mirror 203 performs secondary refraction on the light emitted by the light guide 202, which overcomes the common problem of hard light guides and eliminates the light-emitting effect of thin vertical strips;

[0026] The high-mounted brake light in the above-mentioned structural design has good overall uniformity of light emission, a good sense of luxury in light emission, and a low cost. Specifically, the light guide 202 of the high-mounted brake light completes the first homogenization of the light from the light emitter 201, and the photometric mirror 203 completes the second homogenization of the light from the light emitter 201, eliminating the vertical strip light emission of the light guide 202, and effectively improving the external uniformity of the light from the high-mounted brake light. From a visual point of view, the photometric mirror 203 is a light-emitting surface, presenting a light-emitting effect of a thick-walled part, and a good sense of luxury in light emission. At the same time, the light emitter 201 is arranged at both ends of the accommodating cavity 1b, and only two light emitters 201 are needed to ensure the uniformity of the overall light emission. It can also be applied to extra-long high-mounted brake lights, and the arrangement structure is simple and the overall cost is low.

[0027] In the present embodiment, the light distribution portion 203a is a concave pattern formed on the outer side of the light distribution mirror 203. It can be understood that the concave pattern is specifically manifested as a concave feature relative to the smooth surface, and the concave features are closely arranged; the concave pattern has a good refraction effect on light, and an overall uniform treatment effect on the light emitted by the light guide 202. At the same time, it has a good appearance and a strong texture, which is conducive to further enhancing the high-end sense of luminescence and the aesthetics of the entire vehicle; at the same time, it has a simple structure and is conducive to processing and forming.

[0028] In this embodiment, the lamp housing assembly 1 includes a lamp housing body 101 and a mask 102 fixedly connected to the lamp housing body 101. The mask 102 and the lamp housing body 101 enclose to form the accommodation cavity 1b. Here, the fixing method between the lamp housing body 101 and the mask 102 is not limited, and it can be a snap connection, a screw connection, a welding method, etc. Of course, it can be understood that in order to prevent water leakage, a sealing structure can be provided on each connection surface during connection to ensure the sealing performance of the connection. Here, the mask 102 is also the lamp shade, which is usually located on the side of the lamp housing body 101 facing the rear of the vehicle. It can be understood that the lamp housing body 101 and the mask 102 are usually injection molded parts. In this structural design, the integral lamp housing assembly 1 is formed by the lamp housing body 101 and the mask 102, with a simple structure, which is conducive to separate manufacturing and assembly, thereby further reducing the manufacturing cost.

[0029] In this embodiment, the mask 102 includes a transparent layer 102a and an opaque layer 102b arranged in sequence from outside to inside. The opaque layer 102b is provided with light-transmitting holes 102b1 extending along its own length direction. The part of the transparent layer 102a corresponding to the light-transmitting holes 102b1 constitutes the light-transmitting part 1a. Here, "from outside to inside" means from the outside of the accommodation cavity 1b to the inside. Specifically, the transparent layer 102a and the opaque layer 102b can be injection molded parts, and the two can be formed into a whole by methods such as hot melt welding. The light-transmitting holes 102b1 are long strip holes, and the light distribution part 203a is arranged corresponding to the positions of the light-transmitting holes 102b1. In this structural design, the mask 102 composed of the transparent layer 102a and the opaque layer 102b is conducive to forming a light strip that meets the regulations. At the same time, it has a good texture effect, which is conducive to further improving the overall aesthetics, and the transparent layer 102a located on the outer layer can play a role of sealing and protection.

[0030] In this embodiment, the light distribution lens 203 is fixedly connected to the inner side surface of the mask 102. Here, the "inner side surface" means that the side close to the accommodation cavity 1b is the inner side, and here, snap connection is preferably used for fixation. In this structural design, by fixedly connecting the light distribution lens 203 to the inner side surface of the mask 102, it is conducive to simplifying the overall assembly, thereby further reducing the manufacturing cost.

[0031] In this embodiment, a plurality of protruding limit cards 102c are provided on the inner side surface of the mask 102 along its own length direction, and the light distribution lens 1 is snap-connected to the limit cards 102. Specifically, here, the limit cards 102c and the mask 102 are preferably of an integral structure. By designing the limit cards 102, it is conducive to ensuring the connection stability between the light distribution lens 1 and the mask 102, avoiding the vibration during vehicle driving, especially suitable for an extra-long high-level brake lamp, with good structural reliability, and at the same time, the overall structure is simple to install, which is conducive to further reducing the manufacturing cost.

[0032] In this embodiment, the top of the mask 102 is provided with a rounded corner 102d; here, the "top" refers to the upper part vertically installed behind the vehicle body. By designing the rounded corner 102d structure, the overall aesthetics is good, which is conducive to further improving the overall aesthetics.

[0033] In this embodiment, the lamp housing body 101 is provided with a plurality of raised positioning portions 101a along its length direction; specifically, the positioning portion 101a here includes a main positioning structure located in the middle of the lamp housing body 101 and two secondary positioning structures near the two ends of the lamp housing body 101; the main positioning structure and the secondary positioning structure preferably adopt a cross pin structure. In this structural design, by providing a plurality of positioning portions 101a along its length direction, it is beneficial to ensure the connection stability between the lamp housing body 101 and structures such as vehicle body sheet metal or spoilers, and is particularly suitable for extra-long high-mounted brake lights.

[0034] In this embodiment, the light emitter 201 is fixedly installed at the corresponding end portion of the lamp housing body 101; here, the fixing method of the light emitter 201 and the lamp housing body 101 is not limited, such as screw fixing, etc.; by installing the light emitter 201 on the lamp housing body 101, the installation structure is reliable, the lamp housing body 101 has good strength, the installation position is reasonable, and the installation space is small, which is conducive to further improving reliability and reducing maintenance costs.

[0035] In this embodiment, the light emitter 201 is an LED lamp integrated with a heat sink; the integration of the LED lamp and the heat sink is an existing structure and will not be described in detail here; the use of LED lamps is beneficial to energy saving, and the integrated heat sink can increase the service life of the LED lamp and help reduce maintenance costs; of course, the LED lamp has a fast lighting speed when combined with the light guide.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
