The high-low temperature test box can simulate the temperature change law in the atmospheric environment, so as to test the adaptability of the lens module 60 in the high-temperature, low-temperature comprehensive environment and during use.

[0040] The test tool for the lens module provided by the embodiment of the present application comprises a mounting carrier 10, a first fixing carrier 20, a video monitoring assembly 30 and a third fixing carrier 40. The first fixing carrier 20, the video monitoring assembly 30 and the third fixing carrier 40 are sequentially and spacedly arranged on the mounting carrier 10.

[0041] The mounting carrier 10 is mainly used for carrying the first fixing carrier 20, the video monitoring assembly 30 and the third fixing carrier 40 and the like structure. Therefore, the mounting carrier 10 can be a shell structure, a frame structure or a plate structure. The setting form of the mounting carrier 10 can be adaptively set according to the mounting position and the mounting form of the first fixing carrier 20, the video monitoring assembly 30 and the third fixing carrier 40.

[0042] The first fixing carrier 20 is arranged on the mounting carrier 10, and is used for fixing a lens module 60, which is a lens module 60 to be tested, can be an infrared thermal imaging lens module, or can be a lens module of other types, as long as the lens module 60 used for testing the running state of the lens module 60 under a low-temperature or high-temperature environment can adopt the test tool for the lens module provided in the embodiment of the utility model. The first fixing carrier 20 is mainly used for fixing the lens module 60, and the lens module 60 can be detachably connected to the first fixing carrier 20 through an adapter or the like.

[0043] The video monitoring assembly 30 comprises a second fixing carrier 31 and a lens component 32. The second fixing carrier 31 is movably arranged on the mounting carrier 10 and is arranged in a spaced manner with the first fixing carrier 20. The lens component 32 is movably arranged on the second fixing carrier 31, and the lens component 32 is located in the circumferential direction of the lens module 60, and is used for collecting image information of the lens module 60 running under a low-temperature or high-temperature environment.

When the lens component 32 is provided with two, the two lens components 32 are symmetrically arranged on the second fixing carrier 31. When the lens component 32 is provided with three, the three lens components 32 are arrayed on the second fixing carrier 31 along the circumferential direction of the second fixing carrier 31, so as to meet the purpose of omnidirectional monitoring.

[0045] The third fixing carrier 40 is arranged on the mounting carrier 10 and is arranged in a spaced manner with the second fixing carrier 31. The third fixing carrier 40 is provided with a power supply interface 41 and a data transmission interface 42. The power supply interface 41 is used for supplying power to the lens module 60. The data transmission interface 42 is used for connecting the lens module 60 with an external control device. The data transmission interface 42 can be a network interface and a test cable interface. In other words, the third fixing carrier 40 is similar to the function of a control mainboard, can supply power to the lens module 60 to be tested, and can also communicate and connect the lens module 60 with a control device (such as a computer) outside the test box, so as to control the lens module 60 to run under a low-temperature or high-temperature environment through the external control device, and to observe the running state of the lens module 60 through the lens component 32, so as to eliminate the hardware failure of the lens module 60.

[0046] It can be understood that the test tool for the lens module provided by the embodiment of the utility model, through the first fixed carrier 20, the video monitoring assembly 30 and the third fixed carrier 40 are arranged at intervals on the installation carrier 10.When the lens module 60 to be tested is powered through the power interface 41 on the third fixed carrier 40 and connected with the control device outside the test box through the data transmission interface 42, the lens module 60 is controlled to run in the low-temperature or high-temperature environment through the external control device, so as to observe the running condition of the lens module 60 through the lens part 32, so as to exclude the hardware failure (such as the failure caused by the freezing of the humidity change blocking piece) of the lens module 60, the test efficiency is higher, the test box does not need to be opened for observation during the test, time and labor are saved, the influence on the experimental result is smaller, and the practicality is stronger.

[0047] In addition, the test tool for the lens module can position the position of the lens module 60 through the first fixed carrier 20, so as to replace the installation of the lens module 60 in the use equipment, so as to solve the problem that the whole use equipment (such as a large gimbal device) cannot be put into the test box for testing due to the limited volume of the test box.

[0048] Figure 2 It is the structural schematic view of the first fixed carrier 20 in the test tool for the lens module provided by the embodiment of the utility model.

[0049] Referring to Figure 2 In some embodiments of the utility model, the first fixed carrier 20 includes a sheet metal part, the sheet metal part is detachably connected to the installation carrier 10, the sheet metal part is provided with a positioning part 21 and a fixed part 22, the fixed part 22 is arranged along the circumferential direction of the positioning part 21. The lens module 60 is located at the positioning part 21 and is fixed to the fixed part 22 through a fastener.

[0050] Since the first fixed carrier 20 needs to bear the overall weight of the lens module 60 to be tested, it is necessary to ensure that the first fixed carrier 20 has strong supporting performance and stability, and the sheet metal part is light in weight, high in strength, low in cost and can be mass-produced. The first fixed carrier 20 can be a sheet metal part, and can also be other structures with strong supporting performance and stability.

[0051] Among them, the detachable connection mode between the sheet metal part and the installation carrier 10 can be a fastener such as a bolt or a screw, and can also be matched by using a plug-in mode. For example, a plug-in slot is formed on the installation carrier 10, and the sheet metal part is inserted into the plug-in slot.

[0052] The positioning part 21 is a positioning circular hole structure arranged at the center of the first fixed carrier 20, and the fixing part 22 is a plurality of threaded holes arranged on the first fixed carrier 20 and arranged along the circumferential direction of the center of the circular hole. When the lens module 60 is mounted on the first fixed carrier 20, the lens module 60 is aligned with the threaded holes through the connecting holes on the adapter, and the connecting holes and the threaded holes are fixed by using fasteners such as bolts and screws. At this time, the center line of the lens module 60 can coincide with the center line of the positioning circular hole to achieve the purpose of accurate positioning.

[0053] In this way, the lens module 60 can be completely positioned on the test tool, the position of the lens module 60 is ensured to be unchanged, and the lens module 60 cannot be simulated in the form of being placed in the use equipment after being disassembled alone, so that the test results are different each time.

Since the sliding block 321 is in sliding fit with the guide groove 311, the inner wall of the guide groove 311 can be spaced apart from a damping member such as an elastic protrusion, so that the sliding block 321 on the lens part 32 is prevented from sliding in the guide groove 311 of the sliding ring at will by the damping member. If it is needed to change the position of the lens part 32, a certain force needs to be applied to push the sliding block 321 to pass the damping member to reach another position.

[0058] Of course, the slider 321 can also be arranged on the slip ring, and the guide groove 311 is arranged on the lens component 32, and the specific matching mode is the same as the above mode, and details are not repeated here.
