Description

Technical Field

[0001] This application relates to the field of sunlight simulation environmental chambers, and more particularly, to a lifting device for a lamp group of a sunlight simulation environmental chamber. Background Art

[0002] Currently, for the aging tests of automotive parts and vehicles, a sunlight simulation system is required. Generally, there are only two fixing methods for the sunlight simulation system. One is a fixed type, mainly with a full-spectrum sunlight simulation lamp embedded in the top panel of the test chamber or test cabin. The other is with a lifting mechanism, which is hoisted under the top of the test chamber or the flow deflector of the test cabin. This type with a lifting mechanism is mainly used to adjust the distance from the test piece to adapt to different test piece heights.

[0003] However, both of the above have their limitations. Among them, the fixed type cannot adjust the distance from the test piece and can only achieve the distance from the lighting lamp by lifting the test piece. For the liftable type, since the lamp group and the lifting mechanism are inside the cabin, the heat capacity is large, and the energy saving is poor when conducting tests other than sunlight simulation.

[0009] An end cover assembly provided on the cabin body for opening and closing the opening;

[0010] The lifting device includes a driving component, a connecting frame connected to the lamp body, and a sealing plate for closing the opening; when the lifting device drives the lamp body to descend into the cabin through the driving component, the sealing plate is located at the opening and closes the opening, staying the driving component outside the cabin.

[0011] Further, the driving component includes:

[0012] A first motor fixedly connected to the cabin body;

[0013] A first rotating shaft connected to the output end of the first motor through a coupling;

[0020] The fixed plate is fixedly arranged on the cabin body;

[0021] The first motor, the coupling, the first worm gear steering gear, and the second worm gear steering gear are all fixed on the fixed plate, and one end of the lead screw passes through the fixed plate and is rotationally matched with the fixed plate.

[0022] Furthermore, the projected area of the sealing plate is larger than the projected area of the opening.

[0026] The rotating gear is fixedly arranged on the second rotating shaft;

[0030] Furthermore, the end cover assembly further includes:

[0031] The roller sets are arranged on the cover plate and are slidably matched with the cabin body;

[0040] The beneficial effects of the present application are as follows: When in the non - sunlight simulation test mode, the cover plate moves horizontally towards the opening direction under the action of the rack, the rotating wheel, and the pulley group. When the cover plate is translated to the designated position of the opening, under the guidance of the sunken groove, the cover plate seals the opening of the cabin body tightly. When in the sunlight simulation test mode, first move the cover plate horizontally away from the opening direction, then drive the first motor to lower the lead screw. The lead screw drives the connecting frame to move, and at the same time, lower the lamp body to the predetermined position inside the cabin body. During the lowering process, the sealing plate moves towards the opening direction and abuts against the opening, closing the opening, thereby separating the driving components (except the lead screw) outside the cabin body. Thus, the energy - saving effect during non - sunlight simulation tests can be compensated. It realizes the rapid switching between the sunlight simulation test mode and the non - sunlight simulation test mode, realizes two test modes in one test chamber or test cabin, and saves the input cost and operation cost.
