Description
Technical Field
[0001] This utility model relates to the technical field of vehicle headlight testing, and in particular to a dustproof testing device for automotive headlights. Background Technology
[0002] Automotive headlight dustproof testing is a specific test item for the sealing performance of vehicle headlights. It aims to verify the headlight's protective capability against dust, sand, and other particulate matter, ensuring that its internal components are not contaminated by dust and can maintain normal light efficiency. In the prior art, a utility model patent with patent application number 202320705125.9 discloses an automotive headlight dustproof testing device, which mainly consists of a housing, a fan, and a fixing column. During use, the headlight is fixed inside the housing, and dust is sprayed into the housing while the fan blows the dust onto the headlight. By observing whether the headlight functions normally, it can be inferred whether dust has entered the headlight's internal circuitry and affected its dustproof capability. However, this method has the following problems: because wind direction can change the direction of dust movement, it affects the movement of dust on the headlight surface. Since the headlight in the aforementioned prior art is fixed in position inside the housing, it can only withstand wind from one direction and cannot test the headlight's dustproof capability under different wind directions. This results in high limitations, inconvenience, and poor practicality. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an automotive headlight dustproof testing device that can detect the dustproof capability of vehicle lights under different wind directions, is easy to use, has low limitations, and is highly practical.
[0004] This utility model discloses an automotive headlight dustproof testing device, comprising a base plate, a bracket, a housing, a sealing door, and a clamping mechanism. The housing is fixedly mounted on the upper part of the base plate via the bracket. A chamber is provided inside the housing, and an opening communicating with the chamber is provided at the front end of the housing. The sealing door is installed on the outside of the opening and has an observation window. An exhaust port communicating with the chamber is provided at the upper part of the housing, and a filter cloth is provided on the exhaust port. The device also includes a rotating mechanism, a blower mechanism, and a dust-adding mechanism. The clamping mechanism is mounted on the rotating mechanism and located inside the housing's chamber. The blower mechanism is located to the left of the clamping mechanism and has a blowing function. The dust-adding mechanism is mounted on the housing and has a dust-adding function. The clamping mechanism can be a vise, a three-jaw chuck, a four-jaw chuck, or flat-jaw pliers. When testing the dustproof performance of the headlights, the headlights are first... The headlight is held in place by a clamping mechanism. Then, the headlight is turned on, directing its beam towards the blower mechanism. The blower mechanism is then activated, blowing air onto the headlight surface. Simultaneously, a dust-adding mechanism is activated, continuously adding talcum powder into the chamber. When the talcum powder falls to the right side of the blower mechanism, it is blown towards the headlight, scattering the powder throughout the chamber. This simulates the headlight in a dusty environment. After a period of time, the headlight's ability to maintain its brightness is observed, indicating whether it can function normally in a dusty environment. To test the headlight's dust-proof capability under different wind directions, a rotating mechanism is activated, causing the clamping mechanism and headlight to rotate. This allows the headlight to be blown in different directions by the blower mechanism, thus testing its dust-proof capability under varying wind conditions. This method is convenient to use, has few limitations, and is highly practical.
[0005] Preferably, the rotating mechanism includes an electric turntable and a rotating shaft. The electric turntable is fixedly mounted on the base plate, and the rotating shaft is mounted on the rotating end of the upper part of the electric turntable. The rotating shaft is rotatably mounted on the housing, and the clamping mechanism is fixedly mounted on the upper end of the rotating shaft. When the rotating shaft is rotated, the electric turntable is turned on, and the electric turntable drives the rotating shaft to rotate. The rotating shaft drives the clamping mechanism to rotate, so that different end faces of the clamping mechanism are blown by the blower, thereby detecting the dustproof capability of the clamping mechanism in different wind directions.
[0006] Preferably, the dust collection mechanism includes a feeding funnel and multiple dust collection pipes. The feeding funnel is installed at the upper end of the housing and has a cavity inside. The upper ends of the multiple dust collection pipes are connected to the cavity of the feeding funnel, and the lower ends of the multiple dust collection pipes are connected to the chamber of the housing. The multiple dust collection pipes are located on the right side of the blower mechanism, and each of the multiple dust collection pipes is equipped with a valve. The cavity of the feeding funnel is filled with talc powder. When simulating the dust environment inside the housing chamber, the valves on the multiple dust collection pipes are opened, allowing the talc powder in the feeding funnel to fall into the housing chamber through the multiple dust collection pipes. When the talc powder passes the right side of the blower mechanism during its descent, the blower mechanism blows the talc powder into the housing chamber, simulating the dust environment inside the housing chamber.
[0007] Preferably, the blower mechanism includes a blower, a conveying pipe, and an air blowing pipe. The blower is mounted on the base plate, and the output end of the blower is connected to the air blowing pipe through the conveying pipe. The air blowing pipe is mounted on the housing, and the output end of the air blowing pipe is provided with multiple air blowing pipes, all of which are located on the left side of the housing chamber. When the blower is turned on, air is blown into the housing chamber through the conveying pipe and the air blowing pipe in sequence, dispersing the talcum powder scattered in the housing chamber, simulating the operation of a car headlight in a dusty environment.
[0008] Preferably, the device also includes a dust concentration detector, a light-transmitting plate, a moving mechanism, and a light intensity detection mechanism. The dust concentration detector is mounted on the housing, with its detection end located on the right side of the housing chamber. A light-transmitting plate is located on the right side of the housing. The light intensity detection mechanism is mounted on the moving mechanism, which is used to move the light intensity detection mechanism. When testing the penetrating power of the vehicle headlight's light in a dusty environment, the rotating mechanism is activated, causing the clamping mechanism to rotate the vehicle headlight, thus rotating the headlight's light direction to face the light-transmitting plate. The light emitted by the headlight then passes through the light-transmitting plate and is projected onto the light intensity detection mechanism, which detects the light intensity. Simultaneously, the dust concentration in the housing can be detected by the dust concentration detector.
[0009] Preferably, the moving mechanism includes an electric slide rail and a moving plate. The electric slide rail is mounted on the base plate, and the moving plate is mounted on the electric slide rail. The electric slide rail is used to move the moving plate left and right. The light intensity detection mechanism is mounted on the moving plate. When the electric slide rail is opened, it drives the moving plate to move in the left and right direction, thereby driving the light intensity detection mechanism to move, thereby adjusting the distance between the light intensity detection mechanism and the vehicle headlight, and thus detecting the light intensity of the vehicle headlight at different distances.
[0010] Preferably, the light intensity detection mechanism includes a mounting plate and a light intensity detector. The mounting plate is fixedly mounted on the movable plate, and the light intensity detector is mounted on the mounting plate. The light emitted by the vehicle headlights is transmitted to the light intensity detector after passing through the light-transmitting plate. The light intensity is detected by the light intensity detector, which facilitates the monitoring of the light penetration of the vehicle headlights.
[0011] Compared with the prior art, the advantages of this utility model are: it can detect the dustproof capability of vehicle lights under different wind directions, it is easy to use, has low limitations, and is highly practical. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0019] like Figures 1 to 5This utility model discloses an automotive headlight dustproof testing device comprising a base plate 1, a bracket 2, a housing 3, a sealing door 4, a clamping mechanism 5, a rotating mechanism, a blower mechanism, and a dust-adding mechanism. The housing 3 is fixedly mounted on the upper end of the base plate 1 via the bracket 2. The housing 3 contains a chamber, and the front end of the housing 3 has an opening communicating with the chamber. The sealing door 4 is installed on the outside of the opening and has an observation window. The upper part of the housing 3 has an exhaust port communicating with the chamber, and a filter cloth is installed on the exhaust port. The clamping mechanism 5 is mounted on the rotating mechanism and is located within the chamber of the housing 3. The blower mechanism is located to the left of the clamping mechanism and has a blowing function. The dust-adding mechanism is mounted on the housing 3 and has a dust-adding function. The clamping mechanism 5 can be a vise, a three-jaw chuck, a four-jaw chuck, or flat-jaw pliers. When testing the dustproof performance of automotive headlights… First, the headlight is clamped and fixed using the clamping mechanism 5. Then, the headlight is turned on, directing its beam towards the blower mechanism. The blower mechanism is then activated, blowing air onto the surface of the headlight. Simultaneously, the dust-adding mechanism is activated, continuously adding talcum powder into the chamber 3. When the talcum powder falls to the right side of the blower mechanism, it is blown towards the headlight, scattering the powder throughout the chamber 3, simulating the headlight in a dusty environment. After a period of time, the headlight is observed to determine if it can maintain its brightness, thus indicating whether it can function normally in a dusty environment. When it is necessary to test the headlight's dust-proof capability under other wind directions, the rotating mechanism is activated, causing the clamping mechanism 5 and the headlight to rotate. This allows the headlight to be blown in different directions by the blower mechanism, thus testing its dust-proof capability under different wind directions. This method is convenient to use, has low limitations, and is highly practical.
[0020] like Figure 3 and Figure 4 The rotating mechanism includes an electric turntable 6 and a rotating shaft 7. The electric turntable 6 is fixedly installed on the base plate 1, and the rotating shaft 7 is installed on the rotating end of the upper part of the electric turntable 6. The rotating shaft 7 is rotatably installed on the housing 3, and the clamping mechanism 5 is fixedly installed on the upper end of the rotating shaft 7. When the rotating shaft 7 is rotated, the electric turntable 6 is opened, and the electric turntable 6 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the clamping mechanism 5 to rotate, so that different end faces of the clamping mechanism 5 are blown by the blower, and the dustproof capability of the clamping mechanism 5 in different wind directions can be tested.
[0021] like Figure 3 and Figure 5The dust collection mechanism includes a feeding funnel 8 and multiple dust collection pipes 9. The feeding funnel 8 is installed at the upper end of the housing 3 and has a cavity inside. The upper ends of the multiple dust collection pipes 9 are all connected to the cavity of the feeding funnel 8, and the lower ends of the multiple dust collection pipes 9 are all connected to the chamber of the housing 3. The multiple dust collection pipes 9 are all located on the right side of the blower mechanism, and each of the multiple dust collection pipes 9 is equipped with a valve. The cavity of the feeding funnel 8 is filled with talc powder. When simulating the dust environment in the chamber of the housing 3, the valves on the multiple dust collection pipes 9 are opened, allowing the talc powder in the feeding funnel 8 to fall into the chamber of the housing 3 through the multiple dust collection pipes 9. When the talc powder passes the right side of the blower mechanism during its descent, the blower mechanism blows the talc powder into the chamber of the housing 3, simulating the dust environment in the chamber of the housing 3.
[0022] like Figure 1 and Figure 4 The blower mechanism includes a blower 10, a conveying pipe 11, and an air blowing pipe 12. The blower 10 is mounted on the base plate 1. The output end of the blower 10 is connected to the air blowing pipe 12 through the conveying pipe 11. The air blowing pipe 12 is mounted on the housing 3. The output end of the air blowing pipe 12 is provided with multiple air blowing pipes, all of which are located on the left side of the chamber of the housing 3. When the blower 10 is turned on, the air is blown into the chamber of the housing 3 through the conveying pipe 11 and the air blowing pipe 12 in sequence, which disperses the talcum powder scattered in the chamber of the housing 3, simulating the operation of the car headlights in a dusty environment.
[0023] like Figure 2 and Figure 4 It also includes a dust concentration detector 13, a light-transmitting plate 14, a moving mechanism, and a light intensity detection mechanism. The dust concentration detector 13 is installed on the housing 3, and the detection end of the dust concentration detector 13 is located on the right side of the chamber of the housing 3. The light-transmitting plate 14 is provided on the right side of the housing 3. The light intensity detection mechanism is installed on the moving mechanism, which is used to move the light intensity detection mechanism. When testing the penetrating ability of the headlight's light in a dusty environment, the rotating mechanism is opened, causing the clamping mechanism 5 to rotate the headlight, so that the headlight's light direction is rotated to face the light-transmitting plate 14. Then, the light emitted by the headlight passes through the light-transmitting plate 14 and is projected onto the light intensity detection mechanism. The light intensity is detected by the light intensity detection mechanism, and at the same time, the dust concentration in the housing 3 can be detected by the dust concentration detector 13.
[0024] like Figure 4 The moving mechanism includes an electric slide rail 15 and a moving plate 16. The electric slide rail 15 is mounted on the base plate 1, and the moving plate 16 is mounted on the electric slide rail 15. The electric slide rail 15 is used to move the moving plate 16 left and right. The light intensity detection mechanism is mounted on the moving plate 16. When the electric slide rail 15 is opened, the electric slide rail 15 drives the moving plate 16 to move in the left and right direction, which in turn drives the light intensity detection mechanism to move, thereby adjusting the distance between the light intensity detection mechanism and the vehicle headlight, so as to detect the light intensity of the vehicle headlight at different distances.
[0025] The light intensity detection mechanism includes a mounting plate 17 and a light intensity detector 18. The mounting plate 17 is fixedly mounted on the movable plate 16, and the light intensity detector 18 is mounted on the mounting plate 17. The light emitted by the vehicle headlights is transmitted to the light intensity detector 18 after passing through the light-transmitting plate 14. The light intensity is detected by the light intensity detector 18, which facilitates the monitoring of the light penetration of the vehicle headlights. Example 2
[0026] Based on embodiment 1, a ramp 19 is also included. The ramp 19 is installed at the lower end of the chamber 3 of the housing, and the rotating shaft 7 is rotatably installed on the ramp 19. With the above configuration, when it is not necessary to detect the vehicle lights, the blower mechanism is turned off, allowing the talcum powder floating in the chamber 3 to settle onto the ramp 19 at the lower end of the chamber 3. Then, the talcum powder slides down the inclined surface on the ramp 19 to one end of the chamber 3, which facilitates the cleaning of the talcum powder in the chamber 3.
[0027] The clamping mechanism 5, electric turntable 6, fan 10, dust concentration detector 13, light-transmitting plate 14, electric slide rail 15, and light intensity detector 18 of the automotive lighting dustproof testing device of this utility model are all purchased from the market.
