Description

Technical Field

[0001] This invention relates to the field of clothing testing, and specifically to a clothing pattern comfort testing device and method based on human motion simulation. Background Technology

[0002] During garment production, it is generally necessary to test the garment's fit to the target body shape. This involves motion simulation to obtain the pressure exerted on the body by key areas of the garment, thereby assessing wearing comfort. Current assessment methods typically involve real people wearing the garment, but different body shapes require testers of varying body types, resulting in high labor costs. Some existing technologies use mannequins with multiple joints for motion simulation, then place pressure sensors at key areas to detect the pressure exerted by the garment on the mannequin during the simulation. This pressure data, combined with empirical parameters, is used to assess comfort. However, this method of using pressure sensors struggles to capture full-body pressure changes, and the sensor placement has numerous gaps and blind spots, leading to inaccurate test results. Summary of the Invention

[0003] The purpose of this invention is to provide a clothing pattern comfort testing device and method based on human motion simulation, which solves the problem of many blind spots in existing comfort testing.

[0004] The present invention achieves the above objectives through the following technical solutions: A clothing pattern comfort testing device based on human motion simulation, including A mannequin, used to mimic human movements, including the main body and arms with multiple joints; A multi-axis control unit is used to control the mannequin arm to perform the aforementioned actions; The contour simulation component, worn on the main body, includes multiple air chambers composed of flexible layers. When the air chambers are inflated, the contour of the flexible layers adapts to the garment pattern, and each air chamber is equipped with an exhaust component that opens and closes based on air pressure. The detection module is used to detect the degree of deformation of the contour simulation component; The multi-axis control unit performs actions after the clothing is worn, causing each air chamber to deform under pressure, and identifies the degree of deformation based on the detection module, and evaluates the wearing comfort based on the degree of deformation.

[0005] As a preferred embodiment of the present invention, the mannequin also includes a base, a first joint is provided between the base and the main body, and at least three adjusting cylinders are provided around the first joint. This embodiment is used to simulate the bending and lateral waist movements of the mannequin. The first joint is a ball joint with a full range of rotation angles. The bending and lateral waist direction of the main body is controlled by adjusting the extension and retraction of the cylinders.

[0006] In a preferred embodiment of the present invention, the arm includes an upper arm and a forearm. A second joint is provided between the upper arm and the main body. The forearm and the upper arm are hinged together, and a connector is provided on the forearm. The multi-axis control unit is used to connect with the connector to control the arm movement. This embodiment simulates the joint of the arm by setting a second joint and a hinge. The second joint adopts a ball joint to simulate the shoulder joint, and an elastic part is provided at the end of the upper arm near the second joint. The elastic part is used to simulate the shoulder support of the clothing, and can not affect the range of motion when the second joint simulates human body movement.

[0007] As a preferred embodiment of the present invention, the air chamber is provided with a plurality of traction ropes to maintain the shape of the air chamber when it is inflated. This embodiment allows the shape of the air chamber after inflation to be preset by setting traction ropes, thereby preventing irregular bulging when the air pressure increases.

[0008] As a preferred embodiment of the present invention, the testing device further includes an inflation component, which includes an air pump disposed inside the mannequin and a docking part disposed on the surface of the mannequin. This embodiment uses the inflation component to inflate the contour simulation components in batches.

[0009] As a preferred embodiment of the present invention, a docking assembly is provided at the junction of adjacent air chambers. The docking assembly includes a shell and a docking groove provided on the surface of the shell and adapted to the docking part. A magnetic suction plate is provided in the docking groove. The inflation assembly also includes an electromagnet provided on the mannequin, which is used to attract the shell and docking part to dock. This solution uses a magnetic docking structure so that after the contour simulation component is put into position, the electromagnet automatically attracts the docking inflation port so that it can be automatically inflated.

[0010] As a preferred embodiment of the present invention, the housing is provided with a connecting hole that connects to the surrounding air chambers, and a sliding cylinder for opening and closing the connecting hole is also provided. The sliding cylinder is normally closed by a first elastic element provided in the housing and is opened by electromagnet attraction. By providing the sliding cylinder, the electromagnet can simultaneously inflate the four air chambers, and automatically close after the electromagnet is turned off, so that each air chamber is independent.

[0011] As a preferred embodiment of the present invention, the exhaust assembly includes a housing disposed inside the contour simulation assembly, the two ends of the housing are connected, and a valve plate and a second elastic element for keeping the valve plate normally closed are disposed in the middle. In this embodiment, the exhaust assembly is specifically configured to maintain the valve plate pressure through the second elastic element, and to open the exhaust when the pressure reaches a preset level.

[0012] To implement the above-described testing apparatus, the present invention also proposes a testing method based on any of the above-described testing apparatus, comprising the following steps: S1: Wear the contour simulation component on the main body and wear the clothing on the mannequin; S2: Over-inflate the air chamber until the exhaust components reach the opening pressure, then stop inflating and connect the multi-axis control unit to the arm of the mannequin. S3: The multi-axis control unit simulates upper limb movements multiple times, then the clothing is removed. The deformation degree of each air chamber is obtained based on the detection module, and the wearing comfort is evaluated based on the deformation degree and the location of the air chamber. The beneficial effects of this invention are: This invention uses an inflatable contour simulation component, which is divided into multiple air chambers and plasticized to simulate human body parameters. Each air chamber is equipped with a pressure-activated exhaust component. By monitoring the exhaust of each air chamber during the movement simulation, the pressure-bearing parts on the main body can be effectively observed. The pressure magnitude can be obtained based on the exhaust degree. It has a wide coverage, greatly reduces the monitoring blind zone, and helps to improve accuracy. Attached Figure Description

[0014] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0015] like Figure 1-5As shown, a clothing pattern comfort testing device based on human motion simulation includes a mannequin 1, a multi-axis control unit 2, a contour simulation component 3, and a detection module 7. The mannequin 1 is used to mimic human movements, including a main body 13 and an arm with multiple joints; the multi-axis control unit 2 is used to control the arm of the mannequin 1 to perform movements; the contour simulation component 3 is worn on the main body 13, including multiple air chambers 32 composed of flexible layers 31. After the air chambers 32 are inflated, the contour of the flexible layers 31 is adapted to the clothing pattern, and each air chamber 32 is provided with an exhaust component 5 based on air pressure opening and closing; the detection module 7 is used to detect the degree of deformation of the contour simulation component 3. The multi-axis control unit 2 performs actions after the clothing is put on, so that each air chamber 32 is subjected to pressure and deformed, and identifies the degree of deformation based on the detection module 7, and evaluates the wearing comfort based on the degree of deformation.

[0016] This embodiment uses an inflatable contour simulation component 3, which is divided into multiple air chambers 32 and plasticized to simulate human body parameters. Each air chamber 32 is equipped with a pressure-activated exhaust component 5. By monitoring the exhaust of each air chamber 32 during the motion simulation, the pressure-bearing parts on the main body 13 can be effectively observed. The pressure magnitude can be obtained based on the degree of exhaust (i.e., the degree of deformation of the air chamber 32). It has a wide coverage, greatly reduces the monitoring blind zone, and helps to improve accuracy.

[0017] During implementation, the contour simulation component 3 is worn on the main body 13, and the clothing is worn outside the contour simulation component 3. Then, excess air is injected into the air chamber 32 so that the exhaust components 5 all reach the opening pressure. Then, the inflation is stopped, and the multi-axis control unit 2 is connected to the arm of the mannequin 1. The upper limb movements are simulated multiple times through the multi-axis control unit 2. After the simulation, the clothing is removed. The deformation degree of each air chamber 32 is obtained based on the detection module 7. The wearing comfort is evaluated based on the deformation degree and the location of the air chamber 32. An evaluation comparison table is pre-established between the deformation degree and the wearing comfort, and the comfort is divided into multiple levels. The comfort is then evaluated according to the correspondence between the deformation degree and the wearing comfort.

[0018] In this embodiment, optionally, the detection module 7 can use an AI vision-based industrial camera to determine the degree of deformation by comparing a pre-captured contour, or use radar to scan its three-dimensional contour and determine the degree of deformation by contour comparison.

[0019] Preferably, the mannequin 1 also includes a base 11, a first joint 12 is provided between the base 11 and the main body 13, and at least three adjusting cylinders 14 are provided around the first joint 12. This solution is used to simulate the bending and side-bending movements of the mannequin 1. The first joint 12 is a ball joint with a full range of rotation angles. The bending and side-bending direction of the main body is controlled by adjusting the extension and retraction of the cylinders 14.

[0020] Preferably, the arm includes an upper arm 15 and a forearm 18. A second joint 17 is provided between the upper arm 15 and the main body 13. The forearm 18 and the upper arm 15 are hinged, and a connector 19 is provided on the forearm 18. The multi-axis control unit 2 is used to connect with the connector 19 to control the arm movement. This solution simulates the joint of the arm by setting the second joint 17 and the hinge. The second joint 17 also adopts a ball joint to simulate the shoulder joint. An elastic part 16 is provided at one end of the upper arm 15 near the second joint 17. The elastic part 16 is used to simulate the shoulder support of the clothing and can not affect the range of motion when the second joint 17 simulates the movement of the human body 1.

[0021] Preferably, a number of traction ropes 33 are provided inside the air chamber 32 to maintain the outline of the air chamber 32 when it is inflated. This solution allows the outline of the air chamber 32 after inflation to be preset by setting the traction ropes 33, so as to prevent irregular bulging when the air pressure increases.

[0022] Preferably, the testing device further includes an inflation component 6, which includes an air pump 61 disposed inside the mannequin 1 and a docking part 63 disposed on the surface of the mannequin 1. In this scheme, the inflation component 6 is used to inflate the contour simulation component 3 in batches.

[0023] Optionally, a docking component 4 is provided at the intersection of adjacent air chambers 32. The docking component 4 includes a housing 41 and a docking groove 42 provided on the surface of the housing 41 and adapted to the docking part 63. A magnetic suction plate 43 is provided in the docking groove 42. The inflation component 6 also includes an electromagnet 62 provided on the mannequin 1, which is used to attract the housing 41 to dock with the docking part 63. In this solution, through the magnetic docking structure, after the contour simulation component 3 is put into position, the electromagnet 62 automatically attracts the docking inflation port so that it can be automatically inflated.

[0024] Preferably, the housing 41 is provided with a connecting hole 46 that connects to the surrounding air chambers 32, and a slide cylinder 44 for opening and closing the connecting hole 46 is also provided. The slide cylinder 44 is kept normally closed by a first elastic element 45 provided in the housing 41, and is opened by attraction based on the electromagnet 62. By providing the slide cylinder 44, this solution enables the electromagnet 62 to simultaneously inflate the four air chambers 32, and the slide cylinder 44 automatically closes after the electromagnet 62 is closed, making each air chamber 32 independent.

[0025] Preferably, the exhaust assembly 5 includes a housing 51 disposed inside the contour simulation assembly 3. The two ends of the housing 51 are connected, and a valve plate 52 and a second elastic element 53 for keeping the valve plate 52 normally closed are disposed in the middle. In this solution, the exhaust assembly 5 is specifically configured to maintain the pressure of the valve plate 52 through the second elastic element 53, and to open the exhaust when the pressure reaches a preset level.

[0026] To implement the above-described testing apparatus, the present invention also proposes a testing method based on any of the above-described testing apparatus, comprising the following steps: S1: Wear the contour simulation component 3 on the main body 13 and wear the clothing on the mannequin 1; S2: Over-inflate the air chamber 32 until all exhaust components 5 reach the opening pressure and then stop inflating. Then connect the multi-axis control unit 2 to the arm of the mannequin 1. S3: The upper limb movements are simulated multiple times by the multi-axis control unit 2, and then the clothing is removed. The deformation degree of each air chamber 32 is obtained based on the detection module 7, and the wearing comfort is evaluated based on the deformation degree and the location of the air chamber 32.

[0027] The contour simulation component 3 is worn on the main body 13, so that the docking component 4 and the docking part 63 are roughly aligned. Then, the electromagnet 62 is turned on to attract and dock the magnetic suction plate 43. A sealing ring is also set at the docking point. The clothing is worn on the outside of the contour simulation component 3, and then excess air is injected into the air chamber 32. The air chamber 32 expands until the traction rope 33 is tightened, forming an outer contour corresponding to the preset pattern, so that the exhaust component 5 reaches the opening pressure, that is, the air chamber 32 is full of air. Then, the inflation is stopped, and the multi-axis control unit 2 is connected to the arm of the mannequin 1. The multi-axis control unit 2 simulates upper limb movements multiple times. The clothing in uncomfortable areas will exert pressure on the main body 13, causing the air chamber 32 to exhaust. After the simulation, the clothing is removed. The deformation degree of each air chamber 32 is obtained based on the detection module 7, and the wearing comfort is evaluated based on the deformation degree and the location of the air chamber 32. The above embodiments only illustrate several implementation methods of the present invention. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these modifications and improvements are all within the scope of protection of this invention.
