[0030] With the advancement of technology, people have higher and higher requirements for the aesthetics of car lights. With the emergence of different shapes, slender car lights have also come into being. Conventional designs use circular light guide strips to meet the side requirements of the shape, but considering the unique lighting and shape effects of thick-walled light guides, they have always been favored and pursued by OEMs.

[0031] However, the slender thick-walled light guide has certain defects and it is difficult to achieve side lighting. In addition, its structure may cause uneven light distribution or color difference, which will cause uneven lighting of the entire headlight and low light utilization.

[0032] The present invention provides a vehicle lamp 100 .

[0033] See also Figure 1-Figure 3In one embodiment of the present invention, the vehicle lamp 100 includes a lamp housing 1, a lampshade 2 and a light assembly 3; the lampshade 2 is detachably connected to the lamp housing 1, and an installation space is formed between the lampshade 2 and the lamp housing 1; the light assembly 3 is installed in the installation space, and the light assembly 3 includes a light source 311, a decorative part 33 and a thick-walled light guide 32, the light source 311 is located on the side of the thick-walled light guide 32 away from the lampshade 2, the light source 311 is used to emit light, and the decorative part 33 is used to shield the remaining structures in the installation space except the thick-walled light guide 32; a reflective area 3312 is provided on the decorative part 33, the thick-walled light guide 32 has an inner side surface away from the lampshade 2, the reflective area 3312 is located on the side of the thick-walled light guide 32 where the inner side surface is located, and the shape of the reflective area 3312 matches the shape of the inner side surface, and the reflective area 3312 is used to reflect light irradiated to the reflective area 3312 toward the inner side surface.

[0034] The vehicle lamp 100 of the present invention has a lamp housing 1 and a lampshade 2 which are detachably connected, and a light assembly 3 is arranged in an installation space surrounded by the lamp housing 1 and the lampshade 2, which is convenient for subsequent cleaning and maintenance of the light assembly 3. There is no need to disassemble the entire lamp, and the operation can be performed by simply opening the lampshade 2. Moreover, when the light assembly 3 is damaged, there is no need to replace the entire vehicle lamp 100, which saves costs. Furthermore, the decorative part 33 is used to not only shield the remaining structures in the installation space, but also prevent the remaining structures from being exposed through the lampshade 2 and affecting the beauty of the entire vehicle lamp 100. In addition, by providing a reflective area 3312 on the decorative part 33 and matching its shape with the inner surface of the thick-walled light guide 32, the light irradiated toward the luminous area can be effectively reflected back to the thick-walled light guide 32, and then transmitted through the thick-walled light guide 32 and irradiated toward the lampshade 2, thereby improving the utilization rate of the light emitted by the lamp source 311, and also improving the overall luminous uniformity of the vehicle lamp 100, and achieving a better lighting effect.

[0035] In addition, the decorative piece 33 may also have a specific design to enhance the visual effect when the headlight 100 is turned on, making the entire headlight 100 look brighter or have a unique light and shadow effect.

[0036] The lampshade 2 is a fully transparent lampshade 2 or a partially transparent lampshade 2 to transmit light.

[0037] It should be noted that the light source 311 can be an LED lamp in the prior art, and the remaining structures mentioned above include the light source 311 and the structure on the lamp housing 1 located in the installation space.

[0038] In one embodiment, the decorative member 33 includes a first decorative frame 331 and a second decorative frame 332 detachably mounted above the first decorative frame 331 , wherein the first decorative frame 331 is connected to the lamp housing 1 ; the first decorative frame 331 has a reflector 3311 , and the surface of the reflector 3311 facing the inner side is coated with an aluminum coating, and the aluminum coating forms a reflective area 3312 .

[0039] As can be understood, the reflector 3311 is located on the side of the thick-walled light guide 32 facing away from the lampshade 2. The reflective area 3312 is formed by coating the surface of the reflector 3311 with an aluminum coating. The high reflectivity of the aluminum material significantly improves the reflection efficiency of light, allowing more light to be effectively reflected back to the thick-walled light guide 32 and then emitted to the lampshade 2 through the thick-walled light guide 32, thereby enhancing the overall brightness and lighting effect of the vehicle lamp 100. In addition, the reflective area 3312 formed by the aluminum coating can produce more uniform and soft light reflection, helping to reduce glare and improve nighttime driving safety. Furthermore, the decorative part 33 is divided into a first decorative frame 331 and a second decorative frame 332, and is detachably installed, which not only facilitates component replacement and debugging during the production and assembly process, but also makes it convenient for users or maintenance personnel to replace or clean the decorative part 33 separately in the future, thereby simplifying the maintenance and assembly process. In addition, through the detachable connection method, the first decorative frame 331 and the second decorative frame 332 of different styles or colors can be easily replaced as needed to adapt to different vehicle appearance design requirements or the personalized needs of consumers, thereby increasing the flexibility of product design and market competitiveness.

[0040] In one embodiment, the first decorative frame 331 and the second decorative frame 332 are respectively provided with a corresponding first mounting ear 3313 and a second mounting ear 3321, the first mounting ear 3313 and the second mounting ear 3321 are detachably connected, and the first mounting ear 3313 is provided on the side of the reflector 3311 facing the lamp housing 1; the top of the thick-walled light guide 32 is provided with a third mounting ear 321 that cooperates with the first mounting ear 3313 and the second mounting ear 3321, and the third mounting ear 321 is detachably connected between the first mounting ear 3313 and the second mounting ear 3321.

[0041] It can be understood that by connecting the third mounting ear 321 between the first mounting ear 3313 and the second mounting ear 3321, it can be ensured that the first decorative frame 331 and the second decorative frame 332 firmly fix the thick-walled light guide 32, preventing the thick-walled light guide 32 from loosening or falling off due to vibration or impact during vehicle driving, thereby ensuring the stability and safety of the headlight 100 under various driving conditions; furthermore, the first mounting ear 3313, the second mounting ear 3321 and the third mounting ear 321 have a simple structure and a small size, and do not take up too much installation space, thereby reducing the obstruction of light and improving the utilization rate of light.

[0042] Furthermore, there are multiple first mounting ears 3313 , and the number of the first mounting ears 3313 , the second mounting ears 3321 and the third mounting ears 321 match each other, thereby greatly enhancing the stability of the thick-walled light guide 32 and making the connection more stable.

[0043] In one embodiment, the thick-walled light guide 32 has a limiting protrusion 322, which is formed by protruding upward from the top of the thick-walled light guide 32 to form a limiting step 323 with the top of the thick-walled light guide 32, and the third mounting ear 321 is extended from the limiting protrusion 322 toward the lamp housing 1; the second decorative frame 332 forms a limiting flange 3322, which is extended downward from the side of the second decorative frame 332 away from the lamp housing 1, and the limiting flange 3322 extends into the limiting step 323 and is in limiting contact with the side of the limiting protrusion 322 away from the third mounting ear 321.

[0044] It can be understood that by setting a limiting protrusion 322 on the thick-walled light guide 32, the limiting abutment between the limiting flange 3322 and the limiting protrusion 322 forms a stable supporting position, which does not affect the light transmission of the thick-walled light guide 32 and greatly increases the contact area between the thick-walled light guide 32 and the second decorative frame 332, thereby enhancing the connection strength between the second decorative member 33 and the thick-walled light guide 32, making the thick-walled light guide 32 more stable, so that the second decorative frame 332 can not only limit the upward movement of the thick-walled light guide 32, but also the limiting abutment between the limiting flange 3322 and the limiting protrusion 322 can limit the thick-walled light guide 32 from moving toward the lampshade 2, thereby reducing the risk of the thick-walled light guide 32 shaking up and down due to vehicle driving bumps, and extending the service life of the lighting assembly 3.

[0045] In one embodiment, a screw is passed through the first mounting ear 3313 , and the screw passes through the third mounting ear 321 and is threadedly connected to the second mounting ear 3321 .

[0046] It can be understood that a strong mechanical connection is formed by screws passing through the first mounting ear 3313, the third mounting ear 321 and the second mounting ear 3321. This connection method is more reliable, ensures the stability and safety of the thick-walled light guide during vehicle driving, and is convenient for disassembly and installation.

[0047] In one embodiment, the first decorative frame 331 also has a positioning plate 3314, which is connected to the reflector 3311 and is located on the side of the reflector 3311 facing the lampshade 2; a positioning groove 3315 is provided on the top of the positioning plate 3314, and the notch of the positioning groove 3315 faces the thick-walled light guide 32, and a positioning protrusion 324 is provided at the bottom of the thick-walled light guide 32, which extends into the positioning groove 3315 and abuts against the bottom wall of the positioning groove 3315.

[0048] It can be understood that the positioning groove 3315 on the positioning plate 3314 cooperates with the positioning protrusion 324 at the bottom of the thick-walled light guide 32 to ensure that the thick-walled light guide is accurately positioned during the installation process. This precise positioning mechanism helps to avoid installation errors, ensures the correct alignment between the components, and improves assembly accuracy; furthermore, the positioning protrusion 324 extends into the positioning groove 3315, forming an additional fixed position, which enhances the connection stability between the first decorative frame 331 and the thick-walled light guide 32, and can effectively prevent the thick-walled light guide from shaking or shifting due to vibration or impact during vehicle driving, thereby ensuring the stability and safety of the headlight 100 under various driving conditions.

[0049] In one embodiment, one of the first mounting ear 3313 and the second mounting ear 3321 is further provided with a positioning post 3316 , and the other one is provided with a positioning hole 3323 , and the positioning post 3316 is passed through the positioning hole 3323 .

[0050] As can be understood, the design of positioning post 3316 and positioning hole 3323 ensures accurate positioning of first mounting ear 3313 and second mounting ear 3321 during installation, helping to avoid installation errors. Furthermore, the design of positioning post 3316 and positioning hole 3323 makes the assembly process more intuitive and simple, reducing the time and steps required for manual adjustments. Assemblers simply align positioning post 3316 with positioning hole 3323 and insert it for quick positioning and initial fixation, improving production efficiency. By ensuring the precise relative position of the two decorative frames, the efficiency of screw assembly is also improved.

[0051] It should be noted that, in another embodiment, a positioning column 3316 may be provided on one of the first mounting ears 3313 , and a positioning hole 3323 may be provided on the corresponding second mounting ear 3321 , which results in a smaller structure and a lighter weight.

[0052] In one embodiment, the positioning post 3316 is disposed on the first mounting ear 3313 , and the positioning hole 3323 is opened on the second mounting ear 3321 .

[0053] In one embodiment, a circuit board 31 and a heat-conducting aluminum plate 34 are further provided in the installation space. The light source 311 is provided on one side of the circuit board 31 facing the thick-walled light guide 32 , and the other side of the circuit board 31 facing away from the light source 311 is connected to the heat-conducting aluminum plate 34 .

[0054] As can be understood, by connecting the circuit board 31 to the heat-conducting aluminum plate 34, the heat generated by the lamp 311 can be effectively transferred to the heat-conducting aluminum plate 34. The heat-conducting aluminum plate 34 has good thermal conductivity and can quickly dissipate heat to the outside world, thereby improving the heat dissipation efficiency of the entire system. This helps to maintain the operating temperature of the lamp 311 and the circuit board 31 within a safe range, extending the service life.

[0055] The light source 311 is arranged on the side of the circuit board 31 facing the thick-walled light guide 32. The light emitted by the light source 311 directly irradiates the thick-walled light guide 32, and the thick-walled light guide 32 reflects the light toward the lampshade 2. The light reflected by the thick-walled light guide 32 toward the reflective area 3312 is reflected again toward the thick-walled light guide 32, thereby improving the utilization rate of the light.

[0056] In one embodiment, the lampshade 2 is fastened to the lamp housing 1 by bolts, and a sealing strip is further provided at the connection position between the lamp housing 1 and the lampshade 2 to seal the installation space.

[0057] The use of bolts ensures a firm connection between the lampshade 2 and the lamp housing 1, preventing loosening or falling off due to vibration or impact during driving. The reliability of this fixation improves the overall stability and safety of the car lamp 100; furthermore, the setting of the sealing strip can effectively seal the connection position between the lamp housing 1 and the lampshade 2, preventing external dust, water vapor, dirt, etc. from entering the installation space, which not only protects the internal lighting component 3, but also extends the service life of the car lamp 100.

[0058] In one embodiment, a first connection position is formed on the side of the lamp housing 1 facing the lamp shade 2, and a second connection position is formed on the side of the lamp shade 2 facing the lamp housing 1. One of the first connection position and the second connection position is provided with a sealing groove, and the other is provided with a sealing ridge matching the sealing groove, and the sealing ridge is snapped into the sealing groove.

[0059] It can be understood that by arranging a sealing groove and a sealing ridge between the first connection position and the second connection position, a more effective sealing structure can be formed to prevent water, dust and other impurities from entering the installation space, ensuring its normal operation in various harsh environments; and the snap-fit ​​design of the sealing groove and the sealing ridge can further provide a reliable sealing effect, and can maintain a good sealing state even if the vehicle encounters bumps or vibrations during driving; in addition, the design of the sealing groove and the sealing ridge makes the connection between the lamp housing 1 and the lampshade 2 more intuitive and simple, reducing the manual adjustment time and steps in the assembly process. During assembly, only the sealing ridge needs to be aligned with the sealing groove and inserted to achieve rapid sealing and fixation, thereby improving production efficiency.

[0060] In one embodiment, in order to further improve the sealing performance of the installation space, a sealant is applied to the connection position between the sealing groove and the sealing ridge to form a sealing strip.

[0061] The present invention also proposes a vehicle, which is equipped with the above-mentioned headlight 100. The specific structure of the headlight 100 refers to the above-mentioned embodiment. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
