Description

Technical Field

[0001] The utility model relates to the technical field of headlamp detection, and particularly relates to a solar light focusing test chamber. Background Art

[0002] A headlamp lens can convert the scattered light of a bulb into parallel light. The headlamp with a lens has the advantages of uniform brightness, strong penetration, and small light loss, which can ensure the safe driving of drivers at night.

[0003] However, due to the influence of its own structure, when sunlight passes through the lens, there may be some areas of focus. Solar focusing can generate high temperatures, which can damage the surface structure of the headlamp, and thus the headlamp has a risk of failure. Therefore, when a headlamp with a lens is assembled onto a vehicle, a focusing experiment needs to be carried out to ensure whether the quality of the headlamp with a lens complies with the regulations.

[0004] Existing focusing experimental equipment is too large and occupies a lot of space. For example, the Chinese patent document with the publication number CN210690007U discloses an experimental device for simulating solar light focusing and burning. By placing the test lamp group on the experimental turntable, and installing a semi-circular track on the top of the experimental turntable, a parallel light source is slidably installed on the track to simulate sunlight. As the parallel light source slides on the semi-circular track, different angles of sunlight throughout the day can be simulated. However, in such a test method, to more truly achieve the purpose of simulating sunlight, the radius of the entire track is preferably as large as possible, generally required to be not less than 9 meters. Therefore, for the test chamber, there will inevitably be problems of large space occupation and large volume. Summary of the Utility Model

[0005] In view of this, the utility model provides a solar light focusing test chamber, aiming to be able to carry out a focusing experiment while reducing the space occupied by the equipment.

[0006] To achieve the above object, the technical solution of the utility model is as follows:

A support platform is arranged in the test area, and a lamp holder is installed on the support platform through an angle adjusting mechanism. The lamp holder is used for fixedly assembling the lamp group to be tested. After the lamp group to be tested is fixed on the lamp holder, the light emitted by the light source can be irradiated on the lamp group to be tested through the light guiding channel; the angle adjusting mechanism is used for adjusting the angle of the lamp holder to change the included angle between the corresponding lamp group to be tested and the incident light of the light source.

[0008] With the above structure, by adjusting the angle of the lamp holder through the angle adjustment mechanism, the angle between the lamp under test and the incident light of the light source can be continuously changed, and thus the effect of simulating sunlight at different angles throughout the day can be achieved.

[0009] Preferably, the angle adjustment mechanism includes a turntable, which is horizontally rotatably mounted on the support table through an electric indexing table, and the lamp holder is arranged on the turntable. With the above structure, by driving the turntable to rotate through the electric indexing table, the angle between the lamp under test and the incident light of the light source can be adjusted.

[0028] The present utility model will be further described below in conjunction with embodiments and the accompanying drawings.

[0029] As Figure 1 shown, a solar light focusing test chamber includes a test chamber body A. Inside the test chamber body A, a light guiding channel 3 is installed horizontally. One end of the light guiding channel 3 is provided with a light source 4, and a test area 1a is provided at the other end of the light guiding channel 3. A support platform 5 is installed in the test area 1a. A lamp holder 7 is installed on the support platform 5 through an angle adjusting mechanism 6. The top of the lamp holder 7 is used for fixedly installing a to-be-tested lamp group 17. After the to-be-tested lamp group 17 is fixed on the lamp holder 7, the light emitted by the light source 4 can irradiate on the to-be-tested lamp group 17 through the light guiding channel 3. The angle adjusting mechanism 6 is used to adjust the angle of the lamp holder 7 to change the included angle between the corresponding to-be-tested lamp group 17 and the incident light of the light source 4.

[0030] With such a design, only by adjusting the angle of the lamp holder 7 through the angle adjusting mechanism 6, that is, changing the included angle between the corresponding to-be-tested lamp group 17 and the incident light of the light source 4, the effect of simulating the sunlight irradiating the vehicle lamp at different angles all day long can be achieved. Compared with adjusting the position of the light source 4, the adjustment space required for adjusting the angle adjusting mechanism 6 is smaller, and thus the structure of the entire solar light focusing test chamber is more compact.

[0031] As Figure 2 shown, the angle adjusting mechanism 6 includes a turntable 6a. An electric indexing table 6b is provided at the bottom of the turntable 6a. The turntable 6a is horizontally rotatably installed on the support platform 5 relying on the electric indexing table 6b. The lamp holder 7 is installed on the turntable 6a through an elevation angle adjusting mechanism 7a. The elevation angle adjusting mechanism 7a is used to control the rotation of the lamp holder 7 in the vertical plane. In this embodiment, the elevation angle adjusting mechanism 7a is a telescopic cylinder. Among them, the cylinder block of the telescopic cylinder is rotatably connected to the turntable 6a, and the end of the cylinder rod is hinged to one end of the lamp holder 7. The other end of the lamp holder 7 is hinged to the turntable 6a. With such a design, the angle adjustment of the lamp holder 7 in the vertical direction can be realized through the telescopic cylinder rod. In addition, in this embodiment, the support platform 5 can also be adjusted up and down by a motor drive to meet the detection requirements of different types of lamp groups.

[0032] In this embodiment, the test chamber body A is successively divided into a left chamber 1 and a right chamber 2. Among them, the light guiding channel 3 and the light source are both arranged in the right chamber 2, and a mounting bracket 18 is installed inside the chamber 2. The light source 4 is fixedly supported on the top of the mounting bracket 18. The test area 1a is arranged inside the left chamber 1. In addition, a temperature adjustment area 1b is also arranged in the left chamber 1. The temperature adjustment area 1b is mainly used to control the temperature in the test area 1a to achieve the situation of simulating the sunlight irradiating the vehicle lamp under different ambient temperatures.

[0033] Specifically, as Figure 1As shown, the left chamber 1 and the right chamber 2 are separated by a first partition 8. A light-transmitting hole 8a having the same cross-section as the light guide channel 3 is formed on the first partition 8. An optical lens 9 is installed in the light-transmitting hole 8a. One end of the light guide channel 3 far from the light source 4 abuts against the light-transmitting hole 8a of the first partition 8, so as to ensure that the light emitted by the light source 5 directly hits the test area 1a. In this embodiment, the inner surfaces of the light guide channel 3 are all sprayed with black paint, which can avoid interference caused by the reflection of the light emitted by the light source 4.

[0034] Again, Figure 3 As shown, the test area 1a and the temperature control area 1b are separated by a second partition 14. Ventilation grids 14a are provided at both the bottom and the top of the second partition 14. The ventilation grids 14a are used for gas exchange inside the test area 1a and the temperature control area 1b. In this embodiment, two centrifugal fans 19 are installed at the top of the temperature control area 1b. By setting the centrifugal fans 19, it can be realized that the air flow direction inside the test area 1a is to enter from the bottom ventilation grid 14a and then discharge from the top ventilation grid 14a. In addition, an electric heater and an evaporator are integrated inside the temperature control area 1b and cooperate with the centrifugal fans 19 to achieve the function of controlling the temperature of the test area 1a, and further achieve the simulation of the illumination under different ambient temperatures. Two lighting lamps 20 are also installed at the top of the test area 1a. The lighting lamps 20 are mainly used to illuminate the test area 1a. The lighting lamps 20 adopt a quick-insert design, which is very convenient for disassembly and assembly.

[0035] As Figure 3 and Figure 4 As shown, a first door body 10 is installed on one side of the left chamber 1 close to the test area 1a, and a sealing rubber strip 13 is provided between the first door body 10 and the test chamber A. By setting the first door body 10, it is convenient to place the lamp group 17 to be tested. In this embodiment, the sealing rubber strip 13 is made of a double-layer silicone rubber strip, which has the advantages of high and low temperature resistance, anti-aging, and good sealing performance, and can ensure the stable operation of the test area 1a. An observation port 10a is also formed on the surface of the first door body 10, and a glass observation mirror 11 is installed in the observation port 10a. The glass observation mirror 11 can facilitate the observation of the test situation inside the test area 1a. In this embodiment, to prevent the glass observation mirror 11 from fogging and frosting and other phenomena that affect observation during the test, a resistance film is provided on the surface of the glass observation mirror 11 for heating.

[0036] As Figure 5 As shown, a second door body 12 is installed at the rear end of the right chamber 2. The second door body 12 is convenient for personnel to adjust or repair the light source 4. Similarly, a sealing rubber strip 13 is provided between the second door body 12 and the test chamber A to ensure the airtightness inside the right chamber 2.

[0037] As Figure 5 and Figure 6As shown, the test box body A includes an installation frame 15 and installation plates 16 installed on the circumference and top of the installation frame 15. The installation plates 16 are connected by a splicing and welding process. With such a design, not only is the overall structure very stable, but it is also very convenient for assembly. In this embodiment, the installation plate 16 includes an outer plate 16a, an inner plate 16b, and a heat insulation material 16c arranged between the outer plate 16a and the inner plate 16b. For details, please refer to Figure 7 , in this embodiment, the heat insulation material 16c adopts environmentally friendly polyurethane foam and ultra-fine glass fiber, and has sufficient heat resistance, frost resistance, moisture resistance, heat insulation, and flame retardant properties. When welding adjacent two installation plates 16, sealant is filled between the heat insulation materials 16c, and a lock box 16d is arranged between the two heat insulation materials 16c to strengthen the connection therebetween. The welding position is set on the adjacent inner plates 16b to ensure the aesthetics of the overall structure. In addition, a guiding groove 16b1 is also arranged between adjacent two inner plates 16b to relieve the local stress generated by the deformation of the installation plate 16.

[0038] Finally, it should be noted that the above description is only the preferred embodiment of the present utility model. Under the inspiration of the present utility model, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present utility model. Such transformations all fall within the protection scope of the present utility model.
