A temperature control switch is included, with its detection end extending into the interior of the insulation housing. A sealing baffle is fixedly connected to one end of the upper surface of the material placement cross plate. A photosensitive switch is installed on the inner wall of the insulation housing near the sealing baffle. Balance guide tubes are fixedly connected to both sides of the upper surface of the mounting guide plate. A balance collar is fitted onto the outer side of each balance guide tube, and the top of each collar is fixedly connected to the material placement cross plate. The purpose of this arrangement is to move the material placement cross plate into the interior of the insulation housing using the mounting guide plate, stepper motor, and feed screw. After the sealing baffle approaches the photosensitive switch, the photosensitive switch shuts off the stepper motor, causing the sealing baffle to just close the insulation housing. At this time, the photosensitive switch turns on the air electric heater, which heats the automotive parts to complete the thermal performance test. After the test is completed, the stepper motor can be reversed to reverse the feed screw, removing the material placement cross plate and the tested automotive parts from the insulation housing.

[0006] Preferably, both sides of the upper surface of the mounting guide plate are fixedly connected to connecting upright plates.

[0007] Preferably, each of the connecting plates has two connecting slots on one side, and a positioning hook plate is interspersed between every two adjacent connecting slots.

[0008] Preferably, one end of each positioning hook plate passes through the connecting slot and is fixedly connected to a connecting cross plate.

[0010] Preferably, each of the connecting collars is internally threaded with a positioning screw, and one end of each positioning screw is in contact with the connecting cross plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] (1) This device moves the material placement plate into the interior of the insulation shell through the installation guide plate, stepper motor and feeding screw. After the sealing baffle is close to the photosensitive switch, the photosensitive switch turns off the stepper motor, so that the sealing baffle is just closed to the insulation shell. At this time, the photosensitive switch turns on the air electric heater, and the car parts are heated by the air electric heater to complete the thermal performance test. After the test is completed, the stepper motor can be reversed to reverse the feeding screw, and the material placement plate and the tested car parts can be removed from the insulation shell. It can perform thermal performance tests on smaller protective car parts, which solves the problem that the cost of larger heating chambers is high and that it is easy to waste energy when heating small car parts with its heating chamber.

[0013] (2) The positioning screw and connecting collar can push the connecting cross plate down, so that the positioning hook plate presses the automotive parts and limits the automotive parts. Attached Figure Description
