Description

Technical Field

[0001] The present invention relates to the technical field of automobile lamps, in particular to an automobile lamp capable of preventing condensation from being generated in a lampshade. Background Art

[0002] Automobile lights are essential components for vehicles, primarily providing illumination. Depending on lighting needs, they can adjust the high and low beams. Changes in ambient temperature can also cause changes within the lights. For example, a car light with a condensation-prevention lampshade, documented in publication number CN205504773U, prevents condensation from forming inside the shade during normal use, while also improving the heat dissipation of the light. It also removes condensation that has already formed, and the decorative strips are easily removable. However, this condensation-prevention lampshade still suffers from the following shortcomings in actual use:

[0003] 1. When the temperature difference between the inside and outside of the headlight is too large, condensation will form inside the lampshade, which will not only affect the lighting of the headlight, but also easily cause damage to the components inside the lamp body. However, the traditional method of draining the condensation inside the headlight does not fundamentally solve the problem of condensation inside the headlight;

[0004] 2. In addition, during the use of the headlights, the light source components generate a lot of heat. Due to the high sealing of the headlights, the light source components cannot be cooled by external wind while the vehicle is driving, causing the high temperature inside the headlights to come into contact with condensed water, which can easily cause a short circuit in the headlights.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original automobile headlights. Summary of the Invention

[0006] The purpose of the present invention is to provide an automobile lamp that prevents condensation from forming inside the lampshade, so as to solve the problem that the above-mentioned background technology proposes to discharge the condensation inside the automobile lamp, but does not fundamentally solve the problem of condensation forming inside the automobile lamp, and the light source component of the automobile lamp generates a lot of heat during use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automotive lamp for preventing condensation in a lampshade, comprising a mounting box, a light source assembly being mounted inside the mounting box via bolts, the light source assembly partitioning the interior space of the mounting box, and generating a high degree of heat when in use;

[0008] A lampshade is fixed to the end of the installation box, and an air inlet hole is reserved at the edge of the lampshade;

[0009] include:

[0010] A fixing box is fixed to the side of the installation box, and an air outlet is reserved at one end of the installation box away from the lampshade;

[0011] A liquid storage box is fixedly mounted on the inner wall of the mounting box. The liquid storage box stores liquid for cooling the headlights. A movable shaft is movably inserted into the liquid storage box. The top of the liquid storage box is fixedly connected to one end of a liquid inlet pipe. The other end of the liquid inlet pipe is connected to a first water bag. The first water bag is disposed in the mounting box near the lampshade.

[0012] A connecting tube, one end of which is fixed to the bottom of the installation box, and the other end of the connecting tube is connected to a fixing tube, and the fixing tube is fixed to the side of the support plate, and the support plate is fixed to the lower end surface of the installation box, and at the same time, one end of the fixing tube away from the connecting tube is connected to the bottom of the liquid storage box through a return pipe.

[0013] Preferably, the air inlet is connected to the air outlet through the fixed box, and the movable shaft and the fixed box are connected by a bearing, and a fixed plate is provided at one end of the movable shaft inside the fixed box, and the fixed plates are distributed at equal angles on the movable shaft. Therefore, when the gas enters the fixed box through the air inlet, it can contact the fixed plate and then be discharged from the air outlet.

[0014] Preferably, the outer movable sleeve of the movable shaft is provided with a movable cylinder, a bidirectional threaded groove is provided on the movable shaft, and the movable cylinder and the movable shaft are threadedly connected, and the outer fixed sleeve of the movable cylinder is provided with a guide plate, and the guide plate and the liquid storage box move relative to each other. When the fixed plate is subjected to high-speed wind force, it can rotate and drive the movable shaft to rotate synchronously.

[0015] Preferably, the edge of the guide plate slides in contact with the inner wall of the liquid storage box, and the movement range of the guide plate is equal to 1 / 2 of the length of the liquid storage box, and the liquid storage box and the movable shaft are rotatably connected. When the movable shaft rotates, the guide plate can be moved back and forth through the threaded transmission between the movable cylinder, thereby realizing the circulation of liquid inside the car lamp.

[0016] Preferably, one end of the liquid storage box is connected to the first water bag through a liquid inlet tube, and the first water bag is made of a transparent hard material, and the side of the first water bag away from the lampshade is flat. When the guide plate moves in the liquid storage box, the liquid in the liquid storage box can be transferred to the first water bag through the liquid inlet tube, and the flow of the liquid has a cooling effect.

[0017] Preferably, the first water bag is connected to the fixed tube through a connecting tube, and the fixed tube is arranged in a curved shape on the support plate, and the fixed tube is connected to the other end of the liquid storage box through a return tube. The gas in the first water bag can enter the fixed tube through the connecting tube, so that the liquid can be cooled to a greater extent in the fixed tube and then flow back to the liquid storage box.

[0018] Preferably, a second water bag is attached to the side of the first water bag, and the cross-section of the second water bag is an arc-shaped structure, and a water storage cavity is reserved inside the second water bag. At the same time, the second water bag is made of transparent material. By filling the second water bag with water to expand, or pumping water to maintain a flat state, the lighting range of the car light can be adjusted.

[0019] Preferably, the side of the second water bag is fixedly connected to one end of the water pipe, and a water pump is installed at the other end of the water pipe, and the water storage chamber and the water pipe are connected to each other. At the same time, the water pump is installed at the bottom of the installation box by bolts, and the operation of the water pump can inject external liquid into the second water bag through the water pipe.

[0020] Compared with the prior art, the present invention has the following beneficial effects: the automobile lamp for preventing condensation in the lampshade dissipates heat from the interior of the lamp by circulating liquid inside the lamp, reduces the temperature difference between the interior of the lamp and the outside, prevents condensation from forming inside the lamp, and thus ensures normal lighting of the lamp. The specific contents are as follows:

[0021] 1. When the car is running at high speed, the external wind can enter the fixed box through the air inlet and be discharged from the air outlet after contacting the fixed plate. When the fixed plate is pushed by the gas, it can drive the movable shaft to rotate. In this way, through the threaded transmission between the fixed plate and the movable cylinder, the guide plate can be driven to move back and forth in the liquid storage box, playing the role of guiding the water flow;

[0022] 2. When the guide plate moves back and forth in the liquid reservoir, the gas in the liquid reservoir is transferred to the first water bag through the liquid inlet pipe, thereby dissipating the heat inside the headlight. The liquid then flows into the fixed pipe through the connecting pipe, which can carry away the heat absorbed by the headlight. Because the fixed pipe is curved, it can better withstand the cooling of the external wind. In this way, when it flows back into the liquid reservoir, it can still maintain the lowest temperature, thus achieving efficient heat dissipation inside the headlight.

[0023] 3. The water storage chamber can be filled with water through a water pump, so that the second water bag can be in an expanded state, while the first water bag remains in a static state. The expanded transparent second water bag acts as a convex lens, so that the initial lighting range of the headlight can be adjusted according to demand without affecting the lighting range of the headlight itself.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-8The present invention provides a technical solution: an automobile lamp for preventing condensation in a lampshade, comprising a mounting box 1, a light source assembly 2 being mounted inside the mounting box 1 by bolts, the light source assembly 2 partitioning the interior space of the mounting box 1, and the light source assembly 2 generating high heat when in use; a lampshade 3 being fixed to the end of the mounting box 1, an air inlet 4 being reserved at the edge of the lampshade 3; comprising: a fixing box 5 being fixed to the side of the mounting box 1, an air outlet 6 being reserved at the end of the mounting box 1 away from the lampshade 3; a liquid storage box 11 being fixed to the inner wall of the mounting box 1, the liquid storage box 11 storing liquid for the automobile lamp The cooling liquid, the internal movement of the liquid storage box 11 is penetrated by a movable shaft 7, and the top of the liquid storage box 11 is fixedly connected to one end of the liquid inlet pipe 12, and the other end of the liquid inlet pipe 12 is connected to the first water bag 13, and the first water bag 13 is arranged in the installation box 1 near the lampshade 3; a connecting pipe 14, one end of which is fixed to the bottom of the installation box 1, and the other end of the connecting pipe 14 is connected to a fixed pipe 15, and the fixed pipe 15 is fixed to the side of the support plate 16, and the support plate 16 is fixed to the lower end surface of the installation box 1, and at the same time, the end of the fixed pipe 15 away from the connecting pipe 14 is connected to the bottom of the liquid storage box 11 through a return pipe 17.

[0035] like Figure 1-2 and Figure 4-5 As shown, the air inlet 4 is connected with the air outlet 6 through the fixed box 5, and the movable shaft 7 and the fixed box 5 are connected by a bearing, and a fixed plate 8 is provided at one end of the movable shaft 7 inside the fixed box 5, and the fixed plates 8 are distributed at equal angles on the movable shaft 7. When the car is running at high speed, the external wind can enter the fixed box 5 through the air inlet 4, and then be discharged from the air outlet 6 after contacting the fixed plate 8; the outer movable sleeve of the movable shaft 7 is provided with a movable cylinder 9, and a two-way thread groove is provided on the movable shaft 7, and the movable cylinder 9 and the movable shaft 7 are threadedly connected, and the outer fixed sleeve of the movable cylinder 9 is provided with a guide plate 10, and the guide plate 10 and the liquid storage box 11 move relative to each other. When the fixed plate 8 is driven by the wind, it can rotate and drive the movable shaft 7 to rotate synchronously. In this way, the guide plate 10 can be driven to move in the liquid storage box 11 through the threaded transmission between the movable shaft 7 and the movable cylinder 9.

[0036] like Figure 2-4 and Figure 6As shown, the edge of the guide plate 10 slides in contact with the inner wall of the liquid storage box 11, and the moving range of the guide plate 10 is equal to 1 / 2 of the length of the liquid storage box 11, and the liquid storage box 11 and the movable shaft 7 are rotatably connected; one end of the liquid storage box 11 is connected to the first water bag 13 through the liquid inlet pipe 12, and the first water bag 13 is made of a transparent hard material, and the side of the first water bag 13 away from the lampshade 3 is a flat setting. When the guide plate 10 moves in the liquid storage box 11, the liquid inside it can be transferred to the first water bag 13 through the liquid inlet pipe 12, so that the heat inside the car lamp can be brought into the first water bag 13 to play a heat dissipation role; the first water bag 13 is connected to each other through the connecting pipe 14 and the fixed pipe 15, and The fixed tube 15 is arranged on the support plate 16 in a curved shape, and is connected to the other end of the liquid storage box 11 through the return pipe 17. The liquid in the first water bag 13 can then enter the fixed tube 15 through the connecting pipe 14, thereby taking out the absorbed heat. Since the fixed tube 15 is distributed on the support plate 16 in a curved shape, the flow time outside the headlight is increased, thereby being cooled by the external wind force over a larger range, so that the cooled liquid can flow back to the liquid storage box 11 through the return pipe 17, and can achieve the effect of cooling the interior of the headlight again. Therefore, the circulating flow of the liquid can achieve cyclic cooling of the interior of the headlight, reduce the temperature difference between the interior and the outside, and prevent the generation of condensed water.

[0037] like Figure 6-8 As shown, a second water bag 18 is pasted on the side of the first water bag 13, and the cross-section of the second water bag 18 is an arc-shaped structure, and a water storage chamber 19 is reserved inside the second water bag 18, and the second water bag 18 is made of transparent material; the side of the second water bag 18 is fixedly connected to one end of the water pipe 20, and a water pump 21 is installed at the other end of the water pipe 20, and the water storage chamber 19 and the water pipe 20 are connected to each other, and the water pump 21 is installed at the bottom of the mounting box 1 by bolts. When there is no liquid in the second water bag 18, it is in a state of contact with the first water bag 13. Water can be filled into the second water bag 18 through the water pump 21, and the liquid can enter the water storage chamber 19 through the water pipe 20, which can drive the second water bag 18 to an expanded state. Since the water bags are all transparent, they will not affect the lighting of the car lights, and the expanded second water bag 18 has the function of a convex lens, which is convenient for the user to adjust the initial lighting range of the car lights.

[0038] Working principle: Figure 1-8As shown, the heat generated by the lamp source component 2 during the use of the headlight is relatively high, so it is necessary to dissipate heat inside the headlight to reduce the temperature difference between the inside and the outside and prevent the occurrence of condensation water. When high-speed wind enters the fixed box 5, the movable cylinder 9 can be driven to rotate through the fixed plate 8, and then the guide plate 10 can be driven to move back and forth, so that the liquid in the liquid storage box 11 circulates in the liquid inlet pipe 12, the connecting pipe 14, the fixed pipe 15 and the return pipe 17, which plays a role in dissipating heat inside the headlight, which can not only ensure the normal operation of its internal components, but also prevent the generation of condensation water inside, and effectively extend the service life of the headlight.
