It integrates four major systems: loading, power analysis, temperature acquisition, and temperature control, providing a comprehensive test solution that combines force, electricity, and heat. Its core temperature control equipment adopts a split design, achieving rapid and uniform temperature control through efficient cooling, professional air ducts, and intelligent control, while also offering advantages in energy saving and low noise. This environment provides precise and controllable test conditions for EHA product verification and is a key facility for its research and development and testing.

[0003] Temperature control equipment is a core component of the EHA testing environment, providing precise temperature control for EHA products. It features a split design, with the test chamber covering the test platform to form a sealed space. Key features include: a professional air duct design to ensure temperature uniformity; a high-efficiency evaporator for rapid cooling; and an intelligent control system to dynamically balance energy consumption. Furthermore, the equipment integrates multiple noise reduction technologies such as vibration damping and sound insulation, and is equipped with a high-definition observation window and a double-sealed door, ensuring testing accuracy, reliability, and ease of operation.

[0004] Although the test chamber of the temperature control equipment is equipped with a double-sealed door and a high-definition observation window, which effectively ensures the reliability and convenience of the testing process, after the test is completed at extreme temperatures, opening the door and directly taking out or putting in the product will pose a threat to the operator due to the high or low temperature environment inside, reducing the safety of using the equipment. Utility Model Content

A synchronous belt is sleeved around the outer circumference of the two rollers. A sliding plate is fixedly connected to the side of the placement platform. A connecting block is fixedly connected to the side of the sliding plate. The connecting block is fixedly connected to the side of the synchronous belt.

[0009] A first motor is installed on the side of the experimental chamber, and the first rotating column is fixedly connected to the output end of the first motor.

[0010] The clamping and positioning assembly includes a gear, which is rotatably connected to the middle of the fixed housing. Two racks are slidably connected to the middle of the fixed housing. A connecting plate is fixedly connected to the side of the racks, and a clamping plate is fixedly connected to the side of the connecting plate.

[0011] A support rod is fixedly connected to the side of the connecting plate, and the support rod on one side is slidably connected to the inside of the rack on the other side.

[0012] A second motor is installed on the rear side of the experimental chamber, and the gear is fixedly connected to the output end of the second motor.

[0013] A guide plate is fixedly connected to the front side of the fixed shell, and a guide groove is provided inside the connecting plate. The guide plate is slidably connected inside the guide groove.

[0014] The interior of the fixed shell has multiple slots, and the rack and the support rod are slidably connected inside the multiple slots.

[0015] The bottom shell has a groove inside, and the sliding plate is slidably connected inside the groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, by setting up a transmission mechanism consisting of a first motor driving a rotating column, a rotating wheel, and a synchronous belt, can control the placement platform connected to the synchronous belt to move smoothly out of the test chamber. This allows operators to safely pick up and place test products from the outside without having to put their bodies into the high-temperature or low-temperature dangerous environment inside the chamber, effectively avoiding the risk of burns or frostbite and significantly improving the safety of the equipment.

[0018] 2. This utility model uses a second motor to drive the meshing transmission of a gear and a rack to control the clamping plate to stably hold the test product on the platform. This effectively prevents the test product from shaking due to vibration or its own movement during the test, ensuring the stability of the test conditions. This provides a strong guarantee for obtaining accurate and reliable test data and improves the accuracy of the test results. Attached Figure Description

A second rotating column 8 is rotatably connected to the inner side of the bottom shell 4. Rotary wheels 9 are fixedly connected to the outer sides of both the first rotating column 7 and the second rotating column 8. Rotating the first rotating column 7 controls the rotation of the rotating wheels 9. Synchronous belts 10 are sleeved on the outer circumference of the two rotating wheels 9. Synchronous belts 10 are provided on both sides of the placement platform 5. The rotating wheels 9 control the movement of the synchronous belts 10.

[0030] A slide plate 11 is fixedly connected to the side of the placement platform 5, and a connecting block 12 is fixedly connected to the side of the slide plate 11. The connecting block 12 is fixedly connected to the side of the synchronous belt 10. The placement platform 5 and the synchronous belt 10 are connected through the connecting block 12. When the synchronous belt 10 moves, the placement platform 5 will move synchronously.

[0031] A first motor 13 is installed on the side of the experimental chamber 2, and a first rotating column 7 is fixedly connected to the output end of the first motor 13. The first motor 13 is used to drive the first rotating column 7 to rotate.

[0032] Reference Figure 1 , Figure 5 and Figure 6 The clamping and positioning assembly includes a gear 15, which is rotatably connected to the middle of the fixed housing 6. The fixed housing 6 protects the internal structure. Two racks 16 are slidably connected to the middle of the fixed housing 6. The two racks 16 are symmetrical about the center of the gear 15. A connecting plate 17 is fixedly connected to the side of the rack 16, and a clamping plate 18 is fixedly connected to the side of the connecting plate 17. The rack 16 moves with the clamping plate 18 through the connecting plate 17.

[0033] A support rod 19 is fixedly connected to the side of the connecting plate 17. One support rod 19 is slidably connected to the inside of the rack 16 on the other side, and the movement of the rack 16 is supported by the support rod 19. A second motor 20 is installed on the rear side of the experimental chamber 2. A gear 15 is fixedly connected to the output end of the second motor 20, and the second motor 20 is used to drive the gear 15 to rotate.

[0034] A guide plate 21 is fixedly connected to the front side of the fixed shell 6. A guide groove 22 is provided inside the connecting plate 17. The guide plate 21 is slidably connected inside the guide groove 22. The movement trajectory of the connecting plate 17 is limited by the cooperation between the guide plate 21 and the guide groove 22.

[0035] Reference Figure 2 and Figure 5 The fixed shell 6 has multiple slots 23 inside, and the rack 16 and support rod 19 are slidably connected inside the slots 23.

The movement trajectory of the placement platform 5 is limited by the cooperation between the sliding plate 11 and the sliding groove 14.

[0036] Working principle: After the test is completed, the chamber door 3 is opened, and the first motor 13 is started to control the rotation of a wheel 9 through the first rotating column 7. With the cooperation of the second rotating column 8 and another wheel 9, the synchronous belt 10 is controlled to move. The placement platform 5 is connected to the synchronous belt 10 through the connecting block 12. When the synchronous belt 10 moves, it controls the movement of the placement platform 5, causing it to extend outward. This allows the test product on the placement platform 5 to be removed from the environment inside the test chamber 2 without having to go deep into the test chamber 2, effectively improving the safety of the equipment.

[0037] When the test product is placed on the placement platform 5, the second motor 20 is started to drive the gear 15 to rotate. The rotating gear 15 pushes the rack 16 to move, so that it controls the clamping plate 18 through the connecting plate 17. The clamping plate 18 moves to clamp and position the test product on the placement platform 5, maintaining the stability of the test product and preventing it from shaking, which would affect the accuracy of the test data.
