Description

Technical Field

[0001] The present application relates to the technical field of automobile lamps, and specifically discloses an automobile brake lamp with a three-dimensional thick-wall effect. Background Art

[0002] Generally speaking, automobile lights include lamp body, lamp shell and lamp bezel. The lamp bezel is the structural part around the lamp body. The materials currently used for the bezel are mainly: heat-resistant polycarbonate (PC-HT), polyethylene terephthalate / polybutylene terephthalate (PBT / PET) + MD (mineral filling) and primer-free PBT material, etc. The core purpose is to even out the light;

[0003] At present, the existing daytime running lights with thick-wall effect used on vehicles use thick-wall injection molded block-shaped internal lenses;

[0004] Chinese patent publication number CN206145562U discloses a headlight with a thick-wall effect, including a light pipe, an LED light source circuit board arranged on the light pipe, and an inner lens wrapped around the outer side of the light pipe's exit surface. The light pipe is provided with a light distribution tooth on the side opposite to the exit surface. The light emitted by the LED light source circuit board passes through the light distribution tooth and then diverges from the exit surface to the inner lens. The light emitted by the LED light source circuit board is distributed for the first time by the light distribution tooth on the light pipe, and then diverges from the exit surface, and then is distributed for the second time by the inner lens. The light distribution effect of the light pipe and the light distribution effect of the inner lens are superimposed to form a uniform and gorgeous optical effect, simplifying the injection molding process requirements, facilitating replacement and maintenance, reducing costs, and improving versatility and reliability.

[0005] The internal lens used in the above patent achieves uniform light and thick wall effect in light distribution;

[0006] This method is too costly;

[0007] Our company believes that the traditional method of molding the decorative ring and the thick-walled block-shaped inner lens separately and then assembling them together is the most appropriate, but this method has the following problems: Screws are required for assembly, and they are usually placed on the lamp housing, which results in the thick-walled block-shaped inner lens fixing point being far away from the decorative ring assembly gap and the cantilever being long, and the two parts have the quality risk of friction and powdering during vibration. This results in the need to make the matching gap between the two parts between 1-1.5mm when using this assembly method (a large gap will result in a lack of exquisite appearance), and increasing the gap to avoid powdering due to assembly errors, part tolerances, vibration friction, etc.

[0008] In view of this, the inventor proposes a better assembly method, and therefore, the inventor proposes a car brake light with a three-dimensional thick-wall effect. Utility Model Content

[0009] The utility model aims to solve the problem that a conventional decorative ring and a thick-walled injection-molded block-shaped inner lens move and rub against each other to produce powder when they are separately injection-molded and subsequently assembled.

[0010] In order to achieve the above object, the utility model provides the following basic solutions:

[0011] A three-dimensional thick-walled automobile brake light, comprising

[0012] Car light module and control system: The control system is used to control the lighting and extinguishing of the car light module, and the control system is connected to the car brake system;

[0013] Lamp body: including lampshade and lamp shell;

[0014] Lamp bezel: installed on the inner wall of the lamp housing to diverge the light of the lamp module;

[0015] Mounting plate: fixedly connected to the headlight bezel, with a plurality of through slots formed on the mounting plate;

[0016] Thick-walled injection molded block-shaped internal lens: assembled with the mounting plate and welded to the mounting plate.

[0017] The principles and effects of this basic solution are:

[0018] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The thick-walled injection-molded block-shaped inner lens and the decorative ring are reliably fixed after welding, and will not move relative to each other and rub against each other to produce powder.

[0019] 2. Compared with the prior art, a double-wall thickness structure is adopted, namely an upper block with an inner lens and a lower block with an inner lens, which has a better light uniformity effect.

[0020] 3. Compared with the existing technology, the cost is lower due to separate injection molding and then assembly.

[0021] 4. Compared with the prior art, compared with the traditional method of pre-molding the decorative ring and the thick-walled block-shaped internal lens as one, the advantages are more obvious. Compared with the above scheme, the position of the thick-walled block-shaped internal lens can be adjusted, that is, the welding position can be flexibly adjusted, and the influence of space can be avoided. After the overall welding, there is a problem of inflexible installation space, and this case also avoids this problem.

[0022] Furthermore, the thick-walled injection molded block-shaped inner lens includes an upper block-shaped inner lens and a lower block-shaped inner lens, wherein the upper block-shaped inner lens is higher than the mounting plate as a whole, and the lower block-shaped inner lens is lower than the mounting plate as a whole. The double-walled structure, i.e., the upper block-shaped inner lens and the lower block-shaped inner lens, provides a better light uniformity effect.

[0023] Furthermore, the thickness of the upper block-shaped inner lens is 4 mm, which provides a better light uniformity effect.

[0024] Furthermore, the number of the upper block-shaped internal lenses is the same as the number of the through slots, and the upper block-shaped internal lenses pass through the through slots, so that the subsequent welding position can be clearly identified, which is convenient for welding.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] The reference numerals in the drawings of the specification include: a headlight bezel 1 , a mounting plate 2 , an upper block-shaped inner lens 3 , a lower block-shaped inner lens 4 , a headlight module 5 , a lampshade 6 , and a lamp housing 7 .

[0029] Implementation example Figure 1 As shown:

[0030] A three-dimensional thick-walled automobile brake light, comprising

[0031] The vehicle light module 5 and the control system: The control system is used to control the vehicle light module 5 to light up and turn off, and the control system is connected to the vehicle brake system;

[0032] Specifically, the headlight module 5 is a red light, because the red light is the brake light of the car, and the lighting and extinguishing of the headlight module 5 are controlled by the brake system. When the brake is pressed, the headlight module 5 lights up, and vice versa.

[0033] Lamp body: includes lampshade 6 and lamp housing 7; specifically: lampshade 6 and lamp housing 7 are assembled to form a lamp body, which can be placed at the rear of the car.

[0034] Lamp bezel 1: installed on the inner wall of lamp housing 7 to diverge the light of lamp module 5;

[0035] Mounting plate 2: fixedly connected to the headlight bezel 1, the mounting plate 2 is provided with a plurality of through slots;

[0036] Thick-wall injection molded block-shaped internal lens: assembled with the mounting plate 2 and then welded to the mounting plate 2.

[0037] Specifically: the thick-walled injection molded block-shaped internal lens includes an upper block-shaped internal lens 3 and a lower block-shaped internal lens 4, wherein the upper block-shaped internal lens 3 is higher than the mounting plate 2 as a whole, and the lower block-shaped internal lens 4 is lower than the mounting plate 2 as a whole. The double-walled thick structure, i.e., the upper block-shaped internal lens 3 and the lower block-shaped internal lens 4, has a better uniform light effect, and the thickness of the upper block-shaped internal lens 3 is 4 mm. The uniform light effect is better, and the number of the upper block-shaped internal lens 3 is the same as the number of the through slots, and the upper block-shaped internal lens 3 passes through the through slots. The subsequent welding position can be clarified, which is convenient for welding.

[0038] The installation of this case is different from the traditional installation of car lights:

[0039] The traditional installation is to install the lamp housing 7 first, but in this case, the lamp bezel 1 and the thick-walled injection molded block inner lens are assembled first, and then the upper block inner lens 3 is reasonably inserted into the through groove, and the relative position between the two is adjusted. After the position adjustment is completed, the connection between the thick-walled injection molded block inner lens and the lamp bezel 1 is welded to achieve the determination of the relative position of the thick-walled injection molded block inner lens and the lamp bezel 1;

[0040] Then, install the headlight module 5;

[0041] Finally, the lamp housing 7 wraps the thick-walled injection-molded block-shaped inner lens and the lamp bezel 1 and the lamp module 5, and then the lamp cover 6 is installed. At this point, the entire brake lamp is installed;

[0042] After the brake light is installed, put it into the rear of the car and connect it to the car using screws or other connection methods.

[0043] The device solves the problem that the conventional decorative ring and the thick-walled injection molded block inner lens move and rub against each other to produce powder when they are separately injected and subsequently assembled.

[0044] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
