[0002] High and low temperature low pressure test chambers are key testing equipment that can simultaneously or independently simulate high temperature, low temperature and low pressure environments. Their core function is to collect data inside the chamber in real time through intelligent sensors and temperature sensors, and to use a multivariable coupled PID intelligent algorithm to synchronously control the temperature and pressure in a closed loop.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] The high and low temperature low pressure test chamber for electrical and electronic products disclosed in this invention is mainly used in scenarios where the existing test chamber dehumidification mechanism has not solved the problem of condensation caused by the thermal inertia of the shelf, which will wet the sample, interfere with the data, and corrode the shelf and shorten its life.

[0020] Reference Figures 1-6 A high and low temperature low pressure test chamber for electrical and electronic products, comprising: The test chamber body 1 has a rotating door 4 on one side; Multiple position adjustment components 5 are disposed inside the test chamber body 1, and each of the multiple position adjustment components 5 includes a fixing groove plate 505; Multiple ratchet blocks 6 are respectively set inside the corresponding position adjustment components 5, and the same shelf 2 is set on the multiple ratchet blocks 6; Self-draining decondensation component 3 is installed on shelf 2 and includes two hanging blocks 305 and hook 310.

An inflatable rod 318 is inserted into the interior of each of the two fixing frames 315, and the inflatable end of the two inflatable rods 318 is located inside the hollow rod 313.

One end of each rotating shaft 322 is provided with a driving gear 323, and the two driving gears 323 mesh with the corresponding driven gear ring 324.

[0024] In this invention, the self-draining decondensation component 3 further includes: Two rotary motors 321 are respectively located on the other side of the corresponding lifting block 305, and the drive ends of the two rotary motors 321 are respectively connected to the other end of the corresponding rotary shaft 322 through couplings. Two conversion motors 316 are respectively mounted on corresponding fixed frames 315, and the drive ends of the two conversion motors 316 are respectively connected to one end of the corresponding inflation rod 318 through couplings.

[0025] In this invention, the self-draining decondensation component 3 further includes: A secondary semi-circular groove 312 is mounted on the hook frame 310; A water collection box 325 is disposed on a secondary semi-circular groove 312, and the interior of the water collection box 325 is connected to the interior of the secondary semi-circular groove 312. Two heating cylinders 311 are mounted on a hook frame 310. One end of each heating cylinder 311 is equipped with a drying pump 326, and the air-filling end of the two drying pumps 326 is connected to the interior of the corresponding heating cylinder 311. Two heating elements 327 are respectively disposed inside the heating cylinder 311; Multiple vent pipes 328 are provided, with one end of each vent pipe 328 being inserted into a corresponding heating cylinder 311, and the other end of each vent pipe 328 being inserted into and connected to the interior of a secondary semi-circular groove cylinder 312.

[0026] In this invention, the self-draining decondensation component 3 further includes: Multiple setting plates 308 are respectively set inside the shelf 2, and the same lead screw 303 is set inside two setting plates 308 located on the same side. Two movable blocks 304 are respectively disposed on the outer wall of the corresponding lead screw 303, and support plates 307 are respectively disposed on the two movable blocks 304; Two electric telescopic rods 306 are respectively installed on the upper side of the corresponding support plate 307, and the telescopic ends of the two electric telescopic rods 306 are respectively fixedly connected to the corresponding lifting block 305. Two moving motors 309 are connected to one end of the corresponding lead screw 303 via couplings.

[0027] Specifically, during high and low temperature and low pressure tests on electrical motor products, the shelf 2 inside the test chamber 1 has a certain thermal inertia, making it prone to condensation during rapid temperature changes. Therefore, a self-draining decondensation assembly 3 removes the condensation from the shelf 2. During this process, two moving motors 309 rotate two lead screws 303, causing the moving blocks 304 mounted on the lead screws 303 to move. This moves the absorbent roller 301 across the lower surface of the shelf 2. The contraction of two electric telescopic rods 306 ensures the absorbent roller 301 is in close contact with the lower surface of the shelf 2. Under normal conditions, the two friction airbags 320 do not contact the inner wall of the hollow rod 313. The hollow rod 313, along with the absorbent roller 301, can rotate freely inside the two hanging blocks 305. As the absorbent roller 301 moves along the lower surface of the shelf 2, it absorbs and removes the condensation hanging on the lower surface of the shelf 2. Because the absorbent roller 301 can rotate freely during movement, its absorption area and efficiency are increased. After cleaning the condensation on the lower surface of the shelf 2, the absorbent roller 301 is moved above the secondary semi-circular groove 312. Then, by turning on the two conversion motors 316, the two rotating shafts 322 drive the corresponding drive gears 323 to rotate. Since the two drive gears 323 mesh with the corresponding driven gear rings 324, and the two driven gear rings 324 are fixedly connected to the corresponding connecting sleeve shafts, the two drive gears 323 are engaged with the corresponding driven gear rings 324. On 314, the two connecting sleeve shafts 314 drive the main semi-circular trough 302 to rotate until the main semi-circular trough 302 rotates above the water suction roller 301. Then, the electric telescopic rod 306 extends, causing the main semi-circular trough 302 to descend until the main semi-circular trough 302 and the secondary semi-circular trough 312 merge to form a completely sealed trough space, with the water suction roller 301 located inside the trough space. Then, by turning on the two air pumps 317, the two friction airbags 320 are inflated through the two air rods 318, causing the two friction airbags 320 to expand and tightly adhere to the inner wall of the hollow rod 313. Then, the two conversion motors 316 are turned on to drive the corresponding air rods 318 to rotate, thereby causing the two friction airbags 320 to expand under the action of friction. 20 drives the hollow rod 313 to rotate rapidly, causing the water-absorbing roller 301 to rotate rapidly within the sealed trough space formed by the main semi-circular trough 302 and the auxiliary semi-circular trough 312. This centrifugal force causes water on the water-absorbing roller 301 to detach from its interior, and the detached water is collected in the water collection box 325. Simultaneously, two drying pumps 326 are activated, allowing airflow into the two heating cylinders 311. The airflow is heated by two heating elements 327, and finally, the heated airflow enters the trough space through multiple vent pipes 328, thus drying the drained water-absorbing roller 301. This ensures that the water-absorbing roller 301 remains dry until condensation is removed. Once the water-absorbing roller 301 is dry...Continue the decondensation work.

[0028] In specific application scenarios, the drive roller 301 reciprocates along the lower surface of the shelf 2 to actively clean condensation across the entire surface, ensuring no dead corners. The pressure between the roller 301 and the lower surface of the shelf 2 can be adjusted to ensure close contact and improve condensation absorption efficiency. It also accommodates possible minor deformations of the shelf 2. Under normal conditions, the roller 301 can roll freely during the movement, increasing the contact area and time with the condensation, significantly improving absorption efficiency, and preventing dragging damage to the surface of the shelf 2. Together, they form a complete sealed tank space, providing a closed environment for centrifugal dehydration and hot air drying, preventing water splashing and contaminating the interior of the test chamber 1, while simultaneously collecting condensate. After inflation, the airbag expands and adheres tightly to the inner wall of the hollow rod 313. Driven by the conversion motor 316, the water-absorbing roller 301 rotates at high speed in the sealed groove, efficiently removing adsorbed moisture using centrifugal force. When not in operation, the airbag contracts without interfering with free rotation. Through gear meshing transmission, the flipping angle of the main semi-circular groove 302 is precisely controlled, realizing automatic opening and closing and rotation drive. The operation is reliable and easy to link with the movement stroke of the water-absorbing roller 301. While centrifugally dehydrating, heated and dry airflow is sent into the sealed groove to force-dry the water-absorbing roller 301, ensuring that it remains dry before each decondensation, and preventing secondary condensation or efficiency reduction caused by the moisture of the water-absorbing roller 301 itself.

[0029] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 In a preferred embodiment, the position adjustment component 5 further includes: Multiple guide rods 504 are disposed inside the fixed groove plate 505, and one end of the multiple guide rods 504 located on the same side is provided with the same ratchet plate 502. Multiple locking springs 503 are respectively sleeved on the outer wall of the corresponding guide rod 504. One end of each locking spring 503 is fixedly connected to the outer wall of the fixing groove plate 505, and the other end of each locking spring 503 is fixedly connected to the end of the corresponding guide rod 504 away from the ratchet plate 502.

[0030] In this invention, the position adjustment component 5 further includes: Two fixing plates 501 are disposed opposite to each other on the outer wall of the fixing groove plate 505; Two slide rails 507 are arranged opposite to each other inside the fixed groove plate 505, and two push blocks 508 are respectively provided on the two slide rails 507; Two screws 506 are respectively set inside the mounting holes opened on the opposite side of the corresponding slide rail 507 and the corresponding fixing plate 501.

[0031] In this invention, the position adjustment component 5 further includes: Multiple fixing blocks 509 are respectively disposed on corresponding push blocks 508, and a main fixing rod 510 is provided between two fixing blocks 509 located on the same push block 508. Two movable rings 513 are respectively set on the corresponding screws 506, and the interior of each of the two movable rings 513 is provided with a secondary fixing rod 512; Multiple push-pull plates 511 are respectively disposed on the corresponding main fixing rod 510 and the corresponding secondary fixing rod 512.

[0032] Specifically, before conducting high and low temperature and low pressure tests on electrical motor products, the position of the shelf 2 can be adjusted using the position adjustment component 5. During this process, rotating the two screws 506 causes the corresponding moving rings 513 to approach the corresponding slide rails 507. The two push-pull plates 511 on the corresponding moving rings 513 deflect, thereby pushing the two push blocks 508 away from each other. This pushes the two ratchet plates 502 away from each other, overcoming the spring force of the corresponding locking springs 503. This releases the ratchet plates 502 from engaging the ratchet block 6, allowing the ratchet block 6 to move along the fixed groove plate 505. Similarly, the remaining multiple position adjustments... All components 5 are de-engaged with their internal ratchet blocks 6, allowing multiple ratchet blocks 6 and the shelf 2 to move along multiple fixed slot plates 505. This adjusts the position of the shelf 2 to accommodate electrical and electronic products of different sizes. When the shelf 2 moves to the desired position, rotating multiple screws 506 causes the corresponding moving rings 513 to move away from the corresponding slide rails 507, thereby causing multiple pushing blocks 508 to move away from the corresponding ratchet plates 502. Under the push of the corresponding locking springs 503, the multiple ratchet plates 502 re-engage with the corresponding ratchet blocks 6, thus fixing the multiple ratchet blocks 6 and the shelf 2 in the desired position.

[0033] In specific application scenarios, rotating the screw 506 causes the moving ring 513 to approach the slide rail 507, the push-pull plate 511 deflects and pushes the two push blocks 508 away from each other, thereby driving the ratchet plate 502 to overcome the elastic force of the locking spring 503 and disengage from the ratchet block 6, realizing stepless adjustment of the height of the shelf 2, adapting to electrical and electronic products of different sizes, simple operation and simultaneous adjustment of multiple support points. After rotating the screw 506 in the opposite direction, the moving ring 513 moves away from the slide rail 507, the push block 508 retracts, the locking spring 503 automatically pushes the ratchet plate 502 to reset and re-engage with the ratchet block 6, realizing reliable self-locking, ensuring that the shelf 2 will not shift under test vibration or air pressure changes, and the positioning is stable.

[0034] Working principle: Before conducting high and low temperature and low pressure tests on electrical motor products, the position of the shelf 2 can be adjusted via the position adjustment component 5. During this process, rotating the two screws 506 causes the corresponding moving rings 513 to move closer to the corresponding slide rails 507. The two push-pull plates 511 on the corresponding moving rings 513 deflect, thereby pushing the two push blocks 508 away from each other. This pushes the two ratchet plates 502 away from each other, overcoming the spring force of the corresponding locking springs 503. This releases the ratchet plates 502 from engaging the ratchet block 6, allowing the ratchet block 6 to move along the fixed groove plate 505. Similarly, the remaining multiple position adjustment components can be adjusted. The ratchet blocks 6 inside the component 5 are not engaged, so that multiple ratchet blocks 6 and the shelf 2 can move along multiple fixed slot plates 505 to adjust the position of the shelf 2 to accommodate the placement of electrical and electronic products of different sizes. When the shelf 2 moves to the desired position, the moving ring 513 corresponding to the screw 506 moves away from the corresponding slide rail 507 by rotating multiple screws 506, so that multiple push blocks 508 move away from the corresponding ratchet plates 502. Thus, multiple ratchet plates 502 are pushed by multiple locking springs 503 and re-engage with the corresponding ratchet blocks 6, thereby fixing multiple ratchet blocks 6 and shelf 2 in the desired position. When conducting high and low temperature and low pressure tests on electrical motor products, the shelf 2 inside the test chamber 1 has a certain thermal inertia during the test, making it prone to condensation when the temperature changes rapidly. Therefore, the self-draining decondensation component 3 is used to remove the condensation on the shelf 2. During this process, two moving motors 309 are activated to rotate two lead screws 303, causing the moving blocks 304 sleeved on the two lead screws 303 to move. This causes the water-absorbing roller 301 to move on the lower surface of the shelf 2. The contraction of the two electric telescopic rods 306 ensures that the water-absorbing roller 301 is in close contact with the lower surface of the shelf 2. Under normal conditions, the two friction airbags 320 do not contact the inner wall of the hollow rod 313, so the hollow rod... The rod 313, along with the absorbent roller 301, can rotate freely inside the two hanging blocks 305. As the absorbent roller 301 moves along the lower surface of the shelf 2, it absorbs and removes the condensation hanging on the lower surface of the shelf 2. Because the absorbent roller 301 can rotate freely during movement, its absorption area and efficiency are increased. After cleaning the condensation on the lower surface of the shelf 2, the absorbent roller 301 is moved above the secondary semi-circular groove 312. Then, by turning on the two conversion motors 316, the two rotating shafts 322 drive the corresponding drive gears 323 to rotate. Since the two drive gears 323 mesh with the corresponding driven gear rings 324, and the two driven gear rings 324 are fixedly connected to the corresponding connecting sleeve shafts 31... 4. Therefore, the two connecting sleeve shafts 314 drive the main semi-circular trough 302 to rotate until the main semi-circular trough 302 rotates above the water suction roller 301. Then, the electric telescopic rod 306 extends, causing the main semi-circular trough 302 to descend until the main semi-circular trough 302 and the secondary semi-circular trough 312 merge to form a completely sealed trough space, with the water suction roller 301 located inside the trough space. Then, by turning on the two air pumps 317, the two friction airbags 320 are inflated through the two air rods 318, causing the two friction airbags 320 to expand and tightly adhere to the inner wall of the hollow rod 313. Then, the two conversion motors 316 are turned on to drive the corresponding air rods 318 to rotate, thereby causing the two friction airbags 320 to expand under the action of friction. The hollow rod 313 rotates rapidly, causing the suction roller 301 to rotate rapidly within the sealed trough space formed by the main semi-circular trough 302 and the auxiliary semi-circular trough 312. This centrifugal force causes water on the suction roller 301 to detach from its interior, and the detached water is collected in the water collection box 325. Simultaneously, two drying pumps 326 are activated, allowing airflow into the two heating cylinders 311. The airflow is heated by two heating elements 327, and then enters the trough space through multiple vent pipes 328, thus drying the drained suction roller 301. This ensures the suction roller 301 remains dry until condensation is removed. Once the suction roller 301 is dry...Continue the decondensation work.
