Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a vehicle lamp with a uniform light emitting function. Background Art

[0002] With the development of LED technology and automobiles, the application of LED lights in vehicle lighting is becoming more and more extensive. Now it has gradually replaced the traditional halogen bulbs in vehicle lighting. For example, most of the headlights used in vehicles on the market are LED lights, which enable vehicles to see the road ahead clearly while driving at night.

[0003] At present, most of the LED lamp groups on the market are directly installed inside the headlight cover during use. This will cause the vehicle's lamp cover to be damaged due to rear-end collision or being rear-ended during driving. Then, due to the impact force, the lamp group inside the lamp cover will also be damaged under the action of the impact, and the entire headlight group needs to be replaced.

[0004] The second is the heat dissipation device on the market. Most traditional heat dissipation devices are installed at the rear of the lamp group. During use, only the heat at the rear of the lamp group can flow driven by the heat dissipation device, while the heat dissipated in front of the LED lamp cannot flow in a short time, which causes a large amount of hot air to gather in the refraction cover inside the LED lamp group, which can easily lead to blurred vision of the lamp group due to excessive temperature, causing danger to driving at night.

[0005] In addition, most traditional lamp sets on the market are fixed with bolts and screws during installation. This means that during the subsequent replacement process, construction workers need to use tools to disassemble the lamp set. Moreover, due to the large internal structure of the lampshade, it is inevitable that there will be inconveniences in operation when using tools, which makes disassembly difficult. Summary of the invention

[0006] The purpose of the utility model is to provide a car lamp with a uniform lighting function. When the lampshade is subjected to an impact force to the inside during use, the lampshade will act on a lower connecting plate under the action of the impact force, so that the connecting plate can push the first spring to contract, and then the lampshade can move backward, thereby buffering the impact force, thereby protecting the safety of the lampshade and the bulb, and solving the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: an automobile lamp with a uniform light-emitting function, comprising a mounting plate, a first heat sink is arranged at the center of the upper and lower ends of the mounting plate, and symmetrical heat dissipation holes are opened at the upper and lower ends of the mounting plate, and the adjacent ends of the two heat dissipation holes are in a through-state with the first heat sink;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figures 1 to 8 , the utility model provides a technical solution:

[0037] By adopting the above technical scheme, with the advancement of science and technology, the development of automobile lights is also growing stronger and stronger. In the process of automobile development, various components on the car body are also gradually iterating to meet daily driving needs. Among them, the lights on the car are one of them. With the emergence of LED light groups, traditional halogen headlights have been gradually abolished, so that vehicles can also have a good field of vision during night driving. However, it is inevitable that rear-end collisions or being rear-ended will occur during driving, which will cause the light group to be easily displaced or damaged under the influence of impact force. The structure of this device is as follows, including a mounting plate 1, a through hole of a circular structure is opened at the center of the mounting plate 1 from the left end to the right end, and secondly, the outer corners of the mounting plate 1 are fixed A mounting hole 101 is installed for fixed connection with the connecting parts inside the lamp housing, so that the mounting plate 1 is in a fixed state, and secondly, through holes are opened inside the upper and lower ends of the mounting plate 1, and the through holes at the upper and lower ends are in a through state with the through hole at the center position, and the first heat sink 2 is slidably installed inside the through holes at the upper and lower ends (the outer diameter of the first heat sink 2 is consistent with the inner diameter of the through hole, so during the installation process, it only needs to slide to the inside of the through hole), and then heat dissipation holes 102 are opened from the upper and lower ends of the mounting plate 1 to the center through hole, wherein the adjacent end of the heat dissipation hole 102 is in a through state with the through holes at the upper and lower ends, so during use, the first heat sink 2 can allow the heat emitted by the bulb 9 to flow through the heat dissipation hole 102.

[0038] In addition, vertical cavity grooves 3 are fixedly installed at positions near the edges of the left and right ends of the mounting plate 1, and a slide rod 4 is fixedly installed inside the cavity groove 3. Two slide tables 51 are slidably installed on the circumferential surface of the slide rod 4, and a first spring 5 is fixedly installed between the end of the slide table 51 away from the inner wall of the cavity groove 3, and then a connecting plate 6 is fixedly and rotatably installed on the circumferential surface of the slide table 51. Secondly, a lampshade 7 is arranged at the left end of the mounting plate 1, and the outer surface of the lampshade 7 is rotatably connected to the end of the connecting plate 6 away from the slide table 51 (wherein, during use, the position where the connecting plate 6 is rotatably connected to the slide table 51, because the two connecting rods rotate in opposite directions, so during normal driving, the connecting plate 6 will not have any Rotation, so that the lampshade 7 will not rotate downward or upward, so that the lampshade 7 can only be on the same straight line with the through hole at the center of the mounting plate 1), and then the same cavity groove 3, slide rod 4, first spring 5 and other structures are arranged at the right end of the mounting plate 1, and the connecting plate 6 is rotatably connected with the refraction cover 8 (wherein, under the action of the connecting plate 6, the refraction cover 8 is also on the same horizontal line with the mounting plate 1), secondly, a light bulb 9 is fixedly installed inside the refraction cover 8, and a mounting cavity 10 is fixedly installed on the right end of the refraction cover 8, wherein the right end of the light bulb 9 extends into the interior of the mounting cavity 10, and a circuit is fixedly installed on the right end of the mounting cavity 10, and a wiring harness plug 11 is fixedly installed on the right end of the circuit.

[0039] The left end of the installation cavity 10 is in a concave state to the inside, and then a first through groove 12 is opened on the circumferential surface of the installation cavity 10, and two second through grooves 13 are opened, and the second through grooves 13 are in a symmetrical state, and then a heat dissipation motor 19 is arranged inside the installation cavity 10, wherein two double-headed cavities 16 are fixedly installed on the circumferential surface of the lower end of the heat dissipation motor 19, wherein the double-headed cavities 16 are in a symmetrical state; and grooves 17 are opened from both ends of the double-headed cavity 16 to the inside, and a second spring 18 is fixedly installed inside the groove 17, and an elastic rod 14 is fixedly installed on the far end of the second spring 18, and the far end of the elastic rod 14 is fixedly installed. The end is located on the outside of the elastic rod 14, and secondly, U-shaped buckles 15 are fixedly installed on the upper and lower ends of the outer side of the elastic rod 14. During use, the upper end of the U-shaped buckle 15 can be installed on the two side edges of the first through-slot 12, and the lower end of the U-shaped buckle 15 can be installed on the two end sides of the second through-slot 13, so that the heat dissipation motor 19 can be in a stable state; when in use, the mounting plate 1 is fixedly connected to the internal structure of the headlight lamp group by using the mounting hole 101 at the corner, so that the lampshade 7 and the mounting cavity 10 can be connected to the inside of the lamp group shell, and then the wiring harness plug 11 is plugged into the car's line, so that the bulb 9 can work normally in subsequent use.

[0040] Secondly, during use, after the automobile lamp is impacted, its lampshade 7 will move backward, and then during the movement, it can push the connecting plate 6 to rotate. Therefore, during the rotation, it can push the slide 51 to slide on the circumferential surface of the slide rod 4, so that the impact force can be applied to the first spring 5, and then the impact force can be weakened until it disappears during the repeated rebound of the first spring 5 (wherein, during use, the lampshade 7 needs to be slidably installed inside the lamp assembly shell to avoid the lampshade 7 from sliding during normal driving, and the refractive cover 8 at the right end also needs to be slidably installed inside the lamp assembly shell), and then, under the action of the impact force, the refractive cover 8 can move the same as the lampshade 7 to weaken the damage of the impact force to the lamp assembly; then, during use, a large amount of heat will be generated. At this time, the first radiator 2 is started, and the output shaft of the first radiator 2 will bring The spiral fan blades rotate, so that the heat inside the refraction cover 8 can be discharged along the heat dissipation holes 102 under the action of the airflow, so that the heat inside the refraction cover 8 is gradually in a state of decline, and then, the heat dissipation motor 19 is started. During the use of the heat dissipation motor 19, the heat inside the installation cavity 10 can be gradually reduced under the action of the airflow, so as to reduce the heat generated at the rear end of the bulb 9, and then the internal temperature of the installation cavity 10 is in a low temperature state, so as to avoid damage to the circuit caused by excessive temperature; compared with traditional automobile lights on the market, during the use of the device, under the action of the first spring 5, the slide 51 and other structures, the lampshade 7 and the bulb 9 can buffer the impact force under the action of the connecting rod when the vehicle is impacted, so as to ensure the safety of the lamp group of the internal structure of the lamp shell, avoid the situation of replacing the lamp group as a whole, and save the cost of subsequent maintenance.

[0041] Specifically, Figures 1 to 8 As shown, a refraction cover 8 is provided at the right end of the mounting plate 1, and the outer side of the refraction cover 8 is rotatably connected to the connecting plate 6, a light bulb 9 is fixedly installed inside the refraction cover 8, the right end of the refraction cover 8 is fixedly connected to the mounting cavity 10, and a wiring harness plug 11 is provided at the right end of the mounting cavity 10, grooves 17 are provided from both ends of the double-headed cavity 16 to the inside, a second spring 18 is fixedly installed inside the groove 17, and the end of the adjacent second spring 18 that is away from each other is fixedly connected to the elastic rod 14, a circular through hole is provided at the center position of the mounting plate 1 from the left end to the right end, the outer diameter of the right end of the lampshade 7 is consistent with the inner diameter of the through hole, the right end of the light bulb 9 extends to the inside of the mounting cavity 10, and the light bulb 9, the refraction cover 8 and the lampshade 7 are on the same straight line.

[0042] By adopting the above technical scheme, most of the traditional lamp groups on the market will use bolts or rivets and other structures when being installed inside the lamp housing, so that the heat dissipation device can be in a stable state. However, due to the limited space inside the lamp housing, it is inevitable that when it is fixed with bolts, tools cannot be used. Compared with the cumbersome traditional heat dissipation devices on the market that require tools to be used for disassembly and installation, the present device can achieve timely replacement and installation of the heat dissipation device during use. In use, the first heat sink 2 can be slidably installed inside the through hole, so that in the subsequent replacement and use process, the construction personnel only need to pull out the first heat sink 2 from the inside of the through hole, which saves the construction personnel time for tightening with tools; secondly, the heat dissipation motor 19 can be quickly replaced under the action of the elastic rod 14. For example, during use, the elastic rod 14 is pressed, so that the elastic rod 1 4 can squeeze the second spring 18, so that the elastic rod 14 can bring the heat dissipation motor 19 into the interior of the installation cavity 10, and then under the action of the second spring 18, the elastic rod 14 can bring the U-shaped buckle 15 to gradually approach the edges of the first through-groove 12 and the second through-groove 13 at both ends, and then the edges of the first through-groove 12 and the second through-groove 13 at both ends can be inserted into the interior of the U-shaped buckle 15, so that the heat dissipation motor 19 can be in a stable state, and then in the subsequent replacement and maintenance process, the heat dissipation motor 19 can be disassembled according to the reverse operation of the above steps, thereby saving time and the inconvenience of using tools; compared with the traditional lamp group model on the market, the device can achieve rapid replacement of the heat dissipation motor 19 and the first heat dissipation machine 2, saving time and cost, so that the owner can replace the heat dissipation device by himself after understanding the situation of the vehicle, saving the replacement time and cost consumption of the vehicle.

[0043] Working principle: First, the mounting plate 1 is installed inside the lamp housing through the mounting hole 101, and then the wiring harness plug 11 is connected to the vehicle line.

[0044] Secondly, during use, the lampshade 7 will rotate under the action of impact force, so that the connecting plate 6 can push the slide 51 to slide, thereby causing the first spring 5 to contract and stretch, and the operation is repeated to reduce the impact force and ensure the safety of the lampshade 7, the refraction cover 8, the bulb 9 and the entire lamp assembly.

[0045] Then, the first heat sink 2 is started, so that the heat inside the refraction cover 8 can gradually decrease with the movement of the airflow under the action of the first heat sink 2, thereby ensuring that the heat inside the refraction cover 8 can maintain a suitable temperature and avoiding damage to the bulb 9.

[0046] Finally, during use, the elastic rods 14 at the left and right ends are gradually brought closer together, so that the elastic rods 14 can slide out of the installation cavity 10 with the heat dissipation motor 19, allowing maintenance personnel to quickly replace the heat dissipation motor 19. The second is to directly pull out the first heat sink 2 for maintenance and replacement.

[0047] 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 aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
