Description

Technical Field

[0001] The invention belongs to the technical field of radiation test devices, and in particular relates to a solar radiation test device capable of simulating sunrise and sunset. Background Art

[0002] As the instruction manual Figure 1-2 As shown, this is a device for conducting solar radiation tests on automobiles, in which a plurality of lamp bodies 31 emitting light similar to sunlight are arranged in an array on a hanger 101. The device is suspended on a parallel crane for use. When conducting irradiation tests on automobiles, the automobile is placed under the device, and then each lamp body 31 is lit to conduct a radiation test on the automobile.

[0003] In some radiation tests, the radiation intensity needs to be changed, so the device is provided with a shading net 102 for shading for each lamp body 31 on the hanger 101. In order to drive the shading net 102 to flip, the hanger 101 is also provided with components such as a shading net flipping motor 103 and a transmission shaft 104. The shading state of the lamp body 31 is controlled by controlling the flipping posture of the shading net 102 through the shading net flipping motor 103 in cooperation with the transmission shaft 104. When the lamp body 31 is blocked by the shading net 102, the radiation intensity can be reduced, thereby realizing the adjustment of the radiation intensity.

[0004] Although the radiation test device can adjust the radiation intensity, it is found in actual use that in order to allow the shading net 102 to have enough space to flip, the spacing between the lamp bodies 31 will be wider, which to a certain extent limits the setting density of the lamp bodies 31 on the hanger 101. Therefore, in order to solve the above problem, we propose a solar radiation test device that can simulate sunrise and sunset. Summary of the invention

[0046] The outer side of the C-shaped rail 4 is equipped with a first locking bolt 42 matching the second locking hole 41 through a first elastic pushing component. The first elastic pushing component can push the first locking bolt 42 into the second locking hole 41 under the action of its own elastic force. The inner end of the first locking bolt 42 has a second inclined surface 43 matching the first inclined surface 33.

[0047] A sleeve 5 is fixedly connected to the inner side of the two C-shaped rails 4, and a first piston 51 is sealingly and slidingly connected inside the sleeve 5.

[0049] A hollow heat absorption box is connected between the two sleeves 5, and a shading plate 61 matching the illumination assembly 11 is detachably and fixedly connected to the inner side of the hollow heat absorption box. The lower end of the push rod 53 is lower than the lower end of the shading plate 61. Pressure storage mechanisms are provided on the front and rear sides of the hollow heat absorption box. The hollow heat absorption box and the sleeve 5 are filled with alcohol. When the alcohol expands to generate positive pressure, the pressure storage mechanism can accumulate pressure.

[0050] The pressure storage mechanism includes a pressure storage cylinder 611 fixedly connected to and communicated with the hollow heat absorption box, and the pressure storage cylinder 611 is respectively fixedly connected with a first butt ring 62 and a second butt ring 63 at one end away from the hollow heat absorption box and at one end close to the hollow heat absorption box, a second piston 64 is sealingly and slidably connected inside the pressure storage cylinder 611, and a first spring 65 is provided between the second piston 64 and the first butt ring 62, and the elastic force of the first spring 65 is greater than the sum of the elastic forces of the first elastic pushing component and the second elastic pushing component, and under the action of its own elastic force, the first spring 65 can cooperate with the first butt ring 62 to push the second piston 64 to the side of the second butt ring 63, so that the second piston 64 abuts against the second butt ring 63.

[0051] The elastic support assembly includes two vertical rods 7 fixedly connected to the base plate 2, and the outer sides of the two vertical rods 7 are sleeved with second springs 71. The two C-shaped rails 4 are fixedly connected with slides 72. The two slides 72 can be slidably assembled on the outer sides of the two vertical rods 7 respectively. When the shading assembly 12 is placed on the track frame 1, the slides 72 on both sides can be inserted into the two vertical rods 7 respectively. The vertical rods 7 cooperate with the slides 72 to keep the entire shading assembly 12 in a vertical state. The lower ends of the two slides 72 will respectively abut against the upper ends of the two second springs 71. When the two second springs 71 elastically support the shading assembly 12, the lower end of the push rod 53 is higher than the upper end of the base plate 2.

[0052] The inner and outer sides of the inverted U-shaped track 21 are both provided with a plurality of inner teeth 721 and outer teeth 722 in an array along the running direction thereof; the driving mechanism comprises four guide assemblies, which are distributed in a rectangular shape on the outer side of the plate frame 3, and the guide assemblies comprise a gear seat 73, and the gear seat 73 is rotatably connected with an inner gear 74 and an outer gear 75 which are arranged at intervals; the four guide assemblies are assembled on the front and rear inverted U-shaped tracks 21 in pairs, and the inner gear 74 and the outer gear 75 are respectively meshed with the inner gear 721 and the outer gear 722; the outer side of the plate frame 3 is fixedly connected with drive motors 76 distributed front and back, and the output ends of the two drive motors 76 are respectively connected to an outer gear 75 on the front and rear sides in a transmission manner.

[0053] When the two driving motors 76 drive the two outer gears 75 to rotate forward synchronously, the lighting assembly 11 will be driven to move forward along the inverted U-shaped track 21. In the present embodiment, the lighting assembly 11 will be driven to move from the right side to the left side of the inverted U-shaped track 21. When the two driving motors 76 drive the two outer gears 75 to rotate reversely synchronously, the lighting assembly 11 will be driven to move reversely along the inverted U-shaped track 21.

[0054] The first elastic pushing component includes two cross bars 8 fixedly connected to the outer side of the C-shaped rail 4, the outer ends of the two cross bars 8 are fixedly connected to the first limiting plates 81, a slide plate 82 is slidably connected between the two cross bars 8, the first locking bolt 42 is fixedly connected to the inner side of the slide plate 82, and the outer sides of the two cross bars 8 are both sleeved with third springs 83 located between the slide plate 82 and the first limiting plates 81. In a natural state, the two third springs 83 will cooperate with the first limiting plates 81 under the action of their own elastic force to push the slide plate 82 inward, so that the first locking bolt 42 is inserted into the second locking hole 41.

[0055] The second elastic pushing component includes a third push ring 84 fixedly connected to the inner side of the sleeve 5 and located on the outer side of the first piston 51. A fourth spring 85 is provided between the third push ring 84 and the first piston 51 and is sleeved on the outer side of the push column 511. The fourth spring 85 will cooperate with the third push ring 84 to push the first piston 51 inward under the action of its own elastic force. When the fourth spring 85 is fully extended, the first piston 51 does not extend out of the sleeve 5, and the outer end of the push column 511 does not extend into the inner side of the C-shaped rail 4.

[0056] The third elastic pushing component includes a second limiting plate 86 fixedly connected to the outside of the push rod 53 and located at the lower side of the sleeve 5. A fifth spring 87 located between the sleeve 5 and the second limiting plate 86 is sleeved on the outside of the push rod 53. The fifth spring 87 will cooperate with the second limiting plate 86 and the sleeve 5 to push the push rod 53 downward under the action of its own elastic force, so that the lower end of the second locking bolt 54 abuts against the upper end of the abutting column 511 or the bottom wall of the locking groove 55.

[0057] The hollow heat absorption box includes two main box bodies 9 distributed up and down, and side box bodies 91 extending outward are provided at the front and rear ends of the two main box bodies 9. An intermediate box body 92 is fixedly connected between the two front side box bodies 91 and between the two rear side box bodies 91. The sleeve 5 and the pressure storage mechanism are connected to the intermediate box body 92. A reinforcing rod 93 is provided between the intermediate box body 92 and the C-shaped rail 4. The shading plate 61 is provided on the two main box bodies 9. The two intermediate box bodies 92 distributed up and down can provide more installation points for the shading plate 61, thereby improving the connection strength between the shading plate 61 and the hollow heat absorption box.

[0058] When the shading component 12 is not installed on the illumination component 11, the hollow heat absorbing box will not be directly exposed to the strong irradiation light, so the hollow heat absorbing box will not absorb a large amount of heat, and the alcohol in the hollow heat absorbing box will be in a low temperature state. In this state, the outer end of the support column 511 will not extend into the inner side of the C-shaped rail 4, and the second lock bolt 54 will abut against the bottom wall of the lock groove 55 at this time.

[0059] The device has two main usage states. The first is that the illumination component 11 is used without installing the shading component 12, that is, the test is performed with the strongest radiation intensity. The second is that the illumination component 11 is installed with the shading component 12, that is, the test is performed with a lower radiation intensity.

[0060] When used in state one, the shading component 12 is removed from the elastic support component, and then the car to be tested is placed on the lower side of the track frame 1, and then the lamp body 31 is controlled to light up, and then the entire lighting component 11 is moved on the inverted U-shaped track 21 by controlling the driving mechanism. When the lighting component 11 is in the vertical section of the inverted U-shaped track 21, the radiant light will illuminate the side of the car. When the lighting component 11 gradually moves from the vertical section of the inverted U-shaped track 21 to the horizontal section, the radiant light will gradually move from the side of the car to the top surface of the car, thereby irradiating the top surface of the car. This process simulates the radiation process of the rising sun. On the contrary, when the lighting component 11 gradually moves from the horizontal section of the inverted U-shaped track 21 to the vertical section, the radiant light will gradually move from the top surface of the car to the other side of the car, thereby irradiating the other side of the car. This process simulates the radiation process of the setting sun.

[0061] When used in state two, first let the illumination assembly 11 be located in the horizontal section of the inverted U-shaped track 21, and then insert the shading assembly 12 into the elastic supporting assembly. In this state, the two second springs 71 will support the two shading assemblies 12, so that the lower ends of the push rods 53 are higher than the upper ends of the bottom plates 2. Then, the illumination assembly 11 is controlled to move to the right side of the inverted U-shaped track 21. When the illumination assembly 11 is located above the vertical section on the right side of the inverted U-shaped track 21, the plate frame 3 will be aligned with the two C-shaped rails 4. As the illumination assembly 11 continues to move downward, the plate frame 3 will be inserted into the two C-shaped rails 4. As the plate frame 3 moves downward, the first inclined surface 33 on its lower side will abut against the second inclined surface 43. Under the guiding action of the two inclined surfaces, the first locking bolt 42 will overcome the elastic force of the first elastic pushing assembly and move outward. When the outward movement of the first locking bolt 42 is sufficient for the plate frame 3 to pass through, the lower end of the plate frame 3 It can pass through the first locking bolt 42. At this time, the first locking bolt 42 will abut against the side of the plate frame 3 under the elastic force of the first elastic pushing component. When the first locking hole 32 on the plate frame 3 moves to be aligned with the first locking bolt 42, the first locking bolt 42 will be inserted into the first locking hole 32 under the elastic force of the first elastic pushing component. In this state, the inner wall of the second locking hole 41 will be aligned with the inner wall of the first locking hole 32 on the same side, and there is a gap between the abutment column 511 and the end face on the same side of the plate frame 3. At this time, the shading component 12 is fixedly connected to the lighting component 11. Thereafter, the car to be tested is placed on the lower side of the track frame 1, and then the lamp body 31 is lit. The radiation light emitted by the lamp body 31 will reduce the radiation intensity after being blocked by the shading plate 61. Thereafter, the driving mechanism controls the lighting component 11 to move on the inverted U-shaped track 21 to perform a sunrise and sunset radiation test with a lower radiation intensity.

[0062] During the radiation test in state two, since the shading component 12 is installed on the illumination component 11, the hollow heat absorbing box will be directly exposed to the strong irradiation of the radiation light, so the hollow heat absorbing box will absorb a large amount of heat, and the alcohol in the hollow heat absorbing box will turn to a high temperature state, which will cause the alcohol to expand a part of its volume, that is, a positive pressure will be formed in the hollow heat absorbing box. The positive pressure will play two roles. One is to push the first piston 51 outward so that the inner wall of the lock groove 55 abuts against the second lock bolt 54. In this state, the butt column 511 will not abut against the first lock bolt 42. The second is to push the second piston 64 to the side of the first butt ring 62. This process will compress the first spring 65, that is, the pressure storage mechanism will store pressure.

[0063] After completing the radiation test in state two, when it is necessary to remove the shading component 12, control the illumination component 11 to move to the right side of the inverted U-shaped track 21 while keeping the lamp body 31 in the lit state, that is, keep the illumination component 11 on the vertical section on the right side of the inverted U-shaped track 21, and continue to control the shading component 12 to move downward. After the lower end of the push rod 53 abuts against the bottom plate 2, when the shading component 12 continues to move downward, the push rod 53 will move upward relative to the support column 511. When the second locking bolt 54 exits the locking groove 55, the support column 511 releases the restriction on the rightward movement. Since the lamp body 31 in the lit state will cause the alcohol in the hollow heat-absorbing box to expand due to heat, the pressure storage mechanism at this time accumulates pressure, so at this time The pressure storage mechanism will release the pressure, that is, the first spring 65 rebounds and pushes the second piston 64 to move toward the side of the second resist ring 63. At this time, the alcohol in the hollow heat absorption box will push the first piston 51 to overcome the elastic force of the fourth spring 85 and push the resist column 511 outward, so that the resist column 511 is in contact with the first locking bolt 42 and allows it to overcome the elastic force of the third spring 83 and exit the first locking hole 32. After the first locking bolt 42 exits the first locking hole 32, the plate frame 3 is released from the shading component 12. At this time, the shading component 12 can be pulled upward to complete the disassembly of the shading component 12. The disassembly operation has a high degree of automation. The user only needs to control the lighting component 11 to move on the track frame 1, which is relatively convenient to use.

[0064] After the shading component 12 is removed, it will lose the strong exposure to the radiant light, so the alcohol in the hollow heat-absorbing box will gradually dissipate heat to a low temperature state, and its volume will gradually shrink. At the same time, the second elastic pushing component will drive the first piston 51 and the support column 511 to reset inward together. After the locking groove 55 is aligned with the second locking bolt 54, the third elastic pushing component will drive the second locking bolt 54 to reset downward, so that the second locking bolt 54 is locked into the locking groove 55. In this way, the shading component 12 automatically completes all reset operations without special manual intervention. The next time it is used, it can be directly inserted into the elastic support component for installation and use.

[0065] The shading plate 61 can be made of a screen plate with different mesh sizes or a translucent plate. Since the shading plate 61 is detachably fixedly connected to the hollow heat absorbing box, the shading plate 61 can be removed and replaced to adjust the shading intensity to meet different test needs.

[0066] The illumination component 11 and the shading component 12 of the radiation test device of the present invention are detachably arranged, and the shading plate 61 for shading is arranged as a whole on one side of all lamp bodies 31. When shading is needed, the shading component 12 is installed to achieve shading, and when not needed, it is removed. The disassembly and assembly process is independent of the spacing between the lamp bodies 31 and will not affect the installation density of the lamp bodies 31. In addition, the shading component 12 can be disassembled as a whole, which is easier to clean than the existing radiation test device. Furthermore, the device omits components such as the shading net flipping motor 103 and the transmission shaft 104, which makes the entire device more compact while avoiding related energy consumption.

[0067] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
