Technical Field

[0001] The present invention relates to the technical field of clothing performance detection, and particularly to a testing device for the heat preservation performance of down jackets based on human body temperature simulation. Background Art

[0002] In the clothing manufacturing industry, especially in the production and R & D process of down jackets, it is crucial to accurately test the heat preservation performance of down jackets. This is not only related to the comfort and practicality of products, but also directly affects consumers' purchase decisions and enterprises' market competitiveness. However, there are still many deficiencies in the current testing methods for the heat preservation performance of down jackets. For example, the dummy model used to wear the down jacket to be tested during the detection process is made of hard material (such as the testing device and method for the warmth retention of down clothing disclosed in the published document with the publication number CN113702425B, which discloses this kind of testing device with a hard dummy model). When testing down jackets of different sizes, in order to make the dummy model fit the down jacket, a large number of dummy models (with different sizes) are required.

[0025] Working principle: According to the size of the down jacket to be tested, a human-shaped airbag 7 of a corresponding size is selected, and then the storage component 6 with the human-shaped airbag 7 is controlled to work, so that the walking component 62 drives the storage box 61 to move to the top of the support platform 4, and then the servo motor drives the roller 63 to rotate, and the human-shaped airbag 7 wrapped around the outer wall of the roller 63 is released, and the human-shaped airbag 7 falls above the support platform 4; hot air is filled into the human-shaped airbag 7 (hot air refers to air with a certain temperature) to expand and unfold the human-shaped airbag 7, and the human-shaped airbag 7 is expanded and unfolded. 7 has the same temperature as that of the human body, the detection end of the temperature sensor 5 is fixed to the surface of the human-shaped airbag 7, and then the down jacket to be tested is put on the human-shaped airbag 7, and the test box 1 is closed. The temperature sensor 5 collects the surface temperature of the human-shaped airbag 7 and transmits it to the central control device 2, and then the temperature controller 3 is used to adjust the temperature inside the test box 1 (changing the temperature means lowering the temperature inside the test box 1), and after adjusting the temperature, the surface temperature of the human-shaped airbag 7 is collected, and the thermal insulation performance of the down jacket to be tested is judged by obtaining the surface temperature of the human-shaped airbag 7.

[0026] It should be noted that an inflation port 73 is provided on the human-shaped airbag 7, and the inflation port 73 is used to inflate the interior of the human-shaped airbag 7 or discharge the gas inside the human-shaped airbag 7; after the test is completed, the test box 1 is opened, and the down jacket to be tested is taken off the human-shaped airbag 7, and then the gas inside the human-shaped airbag 7 is discharged, and then the storage component 6 is controlled to work, so that the servo motor drives the roller 63 to rotate in the opposite direction, and after the flexible connecting piece 8 and the human-shaped airbag 7 are wound up, the walking component 62 drives the storage box 61 to move and reset.

[0027] In this embodiment, as a further optimized solution, please refer to Figure 5 Two moving blocks are symmetrically slidably provided in the opening, and a guide roller 65 is rotatably provided on the moving block. A driving device 64 (such as an electric cylinder) is provided in the inner cavity of the opening, and the moving end of the driving device 64 is connected to the moving block; when the winding roller 63 rotates to release the human-shaped airbag 7, there is a large distance between the two guide rollers 65, which will not affect the movement of the human-shaped airbag 7 from the inside of the storage box 61; when the winding roller 63 rotates to wrap and store the human-shaped airbag 7, the driving device 64 drives the two guide rollers 65 to be close, so that the human-shaped airbag 7 will be squeezed by the two winding rollers 63 when moving to the inside of the storage box 61, which is used to discharge the residual gas inside the human-shaped airbag 7 and reduce its volume to facilitate its winding and storage.

[0028] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 and Figure 3, a driving member 10 (such as an electric telescopic rod) is provided at the top of the support platform 4. A support plate 9 is provided on the moving end of the driving member 10 (the support plate 9 can move up and down). A fixing member 13 is provided on the side of the human-shaped airbag 7 away from the storage assembly 6. Among them, the fixing member 13 includes a clamping member 131 (a fixture) and a second magnetic member 132 connected to the clamping member 131. The clamping member 131 clamps the bottom of the human-shaped airbag 7. A first magnetic member 12 is provided on the top of the support plate 9 (both the first magnetic member 12 and the second magnetic member 132 are magnetic blocks). The sides of the first magnetic member 12 and the second magnetic member 132 close to each other have opposite magnetic poles, and attraction will be generated when they approach each other; when the human-shaped airbag 7 is released from the storage box 61, the driving member 10 drives the support plate 9 to move up, so that the first magnetic member 12 and the second magnetic member 132 approach and attract each other, fixing the bottom of the human-shaped airbag 7, and then the driving member 10 drives the support plate 9 to move down and reset.

[0029] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 3 , there are two fixing members 13, and the two fixing members 13 are respectively arranged on both sides of the bottom of the human-shaped airbag 7; a connecting rod 14 is provided between the two second magnetic members 132; with the support of the connecting rod 14, the distance between the two second magnetic members 132 remains unchanged. After the second magnetic member 132 is adsorbed by the first magnetic member 12, the bottom of the human-shaped airbag 7 will not be bent.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 2 , an opening 71 is provided at the bottom of the human-shaped airbag 7, and a telescopic support rod 11 (such as an electric telescopic rod) is provided on the support plate 9; after the second magnetic member 132 is adsorbed by the first magnetic member 12, the telescopic support rod 11 extends and inserts into the opening 71 for supporting the human-shaped airbag 7, so that the human-shaped airbag 7 can support the tested down jacket.

[0031] It should be noted that if the opening 71 and the telescopic support rod 11 are misaligned, the position of the human-shaped airbag 7 can be moved for adjustment; the opening 71 extends to the head of the human-shaped airbag 7; in order to make the human-shaped airbag 7 more stable, there are multiple openings 71 and telescopic support rods 11. The multiple openings 71 are opened at the bottom of the human-shaped airbag 7 and extend upward, and the multiple openings 71 are all located in the body part of the human-shaped airbag 7.

[0032] In this embodiment, as a further optimized solution, please refer to Figure 2 , a plurality of flexible heat-conducting members 72 (such as heat-conducting silica gel) are provided on the surface of the human-shaped airbag 7, and the plurality of flexible heat-conducting members 72 extend into the human-shaped airbag 7; the heat of the gas inside the human-shaped airbag 7 is transferred out by the flexible heat-conducting members 72, so that the human-shaped airbag 7 can normally dissipate heat to the outside, reduce the interference of the human-shaped airbag 7 on the heat preservation test, and ensure the accuracy of the down jacket heat preservation test.
