[0066] Figure 1 A schematic structural diagram of a test dummy according to an embodiment of the present invention is shown. Figure 2 A top view of a test dummy according to an embodiment of the present invention is shown. Figure 3 A side view of a test dummy according to an embodiment of the present invention is shown. As shown in the figure, a test dummy 100 mainly includes a dummy body 101, a dummy jacket 102, a body temperature regulating device 103, a sweating device 104, a sensor assembly and an electric control box 105.

[0067] The dummy body 101 includes a back component 106 and a hip component 107 that are connected to each other. The back component 106 and the hip component 107 can be made of an aviation-grade aluminum alloy frame, which can significantly reduce the overall mass while ensuring structural rigidity and ensure dimensional stability. Various standard interfaces can be set on the aviation-grade aluminum alloy frame to support the rapid installation of various sensor components.

[0068] The dummy coat 102 is wrapped around the back of the dummy body 101. The dummy coat 102 is used to simulate the muscles and skin of the human body. During the test, when subjected to external pressure, friction or slight deformation, the dummy coat 102 can realistically simulate the corresponding state changes of the human muscles and skin, providing more real and reliable surface feedback for the test.

[0069] The body temperature regulating device 103 is disposed on the back surface of the dummy body 101 and is located between the dummy body 101 and the dummy jacket 102. The body temperature regulating device 103 is used to regulate the body surface temperature of the test dummy 100, simulate the temperature change of the human body under different ambient temperatures, and ensure the diversity and authenticity of the test conditions.

[0070] The sweating device 104 is connected to the mannequin jacket 102. The sweating device 104 is used to simulate the sweating state of the test mannequin 100. Based on the principle of evaporation and heat dissipation of sweat, the sweating device 104 can effectively cool down the mannequin, further approaching the real physiological heat dissipation mechanism of the human body, and providing practical environmental conditions for relevant tests.

[0071] The sensor assembly is arranged on the dummy body 101. The sensor assembly is used to obtain status data of the test dummy 100 in different test scenarios.

[0072] The electric control box 105 is connected to an external display screen (not shown). On the one hand, the electric control box 105 is used to collect the status data obtained by the sensor assembly and send it to the external display screen, presenting it to the tester in an intuitive and clear visual interface, so that the tester can grasp the test dynamics in real time. On the other hand, the electric control box 105 is also used to control the body temperature adjustment device 103 to achieve temperature control of the test dummy 100.

[0073] In some examples, the mannequin jacket 102 is a layered structure, with a waterproof layer, a sponge layer and a breathable layer arranged in sequence from the inside to the outside. The waterproof layer can be made of a special polymer material with waterproof properties to block the penetration path of the simulated sweat generated by the sweating device 104 inside the mannequin, ensuring that the temperature regulating device 103 and various sensor components located on the mannequin body 101 are always in a dry environment to avoid short circuits, failures and other faults due to liquid erosion. The sponge layer can be made of a high-density, high-elasticity sponge material. It has a buffering property, and when the test encounters external pressure shock or extrusion, it plays a good buffering and supporting role like human muscles. Moreover, the sponge layer has a certain liquid storage capacity, and its porous structure can absorb and temporarily store part of the simulated sweat, and then release it outward in a slow and continuous manner to simulate the continuity of the human sweating process. The outermost layer is set as a breathable layer, which can be made of a highly breathable textile material, and its fibers are interwoven to form a fine microporous network. On the one hand, these micropores allow outside air to freely flow in and out, similar to the breathing function of human skin, so that the surface of the mannequin jacket 102 always maintains a dry and comfortable state; on the other hand, the breathable layer and the sponge layer work together. When the simulated sweat evaporates, the smooth flow of air can accelerate the vaporization and heat dissipation of sweat, and enhance the cooling efficiency of the sweating device 104, so that the mannequin can be more in line with the actual physiological performance in simulating the sweating and heat dissipation mechanism of the human body.

[0074] In some examples, the sweating device 104 includes a liquid storage tank 108 and a peristaltic pump 109. The peristaltic pump 109 is connected to the sponge layer of the dummy coat 102 through a hose. The peristaltic pump 109 is used to deliver simulated sweat to the sponge layer. It should be noted that the peristaltic pump 109 is a fluid delivery device that works based on the principle of roller squeezing hose. It has precise flow control capabilities and can accurately adjust the output rate of simulated sweat according to instructions. As mentioned above, the pumped simulated sweat will quickly diffuse and store in the sponge layer, and slowly and naturally penetrate the simulated sweat into the breathable layer of the dummy coat 102, presenting a realistic sweating effect.

[0075] Figure 4A schematic structural diagram of a body temperature regulating device and a sensor assembly on a back assembly according to an embodiment of the present invention is shown. Figure 5 A schematic diagram of the structure of a temperature regulating device and a sensor assembly on a hip assembly of an embodiment of the present invention is shown. In some examples, the sensor assembly includes a pressure sensor 110, a wind speed sensor 111, and a temperature and humidity sensor 112. The pressure sensor 110 can sense the size and direction of pressure applied to different parts of the dummy by the outside world. During the test, whether it is under the pressure of heavy objects, collision impact, or the pressure distribution of various parts of the dummy's body in different postures, the pressure sensor 110 can convert these mechanical information into electrical signals and transmit them to the electrical control box 105 in real time, providing key data for subsequent evaluation of the state of the dummy under various stress conditions. The wind speed sensor 111 is of great significance in simulating the heat dissipation, wind blowing feeling, and aerodynamic-related tests of the human body under different wind speed conditions, and helps to restore the impact of the actual environment on the human body. The temperature and humidity sensor 112 is used to monitor the temperature and humidity changes of the surrounding environment of the dummy and the surface of the dummy itself. When the body temperature regulating device 103 and the sweating device 104 are working, the temperature and humidity sensor 112 can accurately sense the rise and fall of the dummy's surface temperature and the changes in the body surface humidity, providing accurate data basis for the subsequent evaluation of the effects of body temperature regulation and sweating simulation.

[0076] In some examples, the electric control box 105 is arranged on the hip assembly 107. Such arrangement can, on the one hand, enable the dummy to maintain good center of gravity stability during placement and use, and avoid the dummy from tilting or being unstable due to improper position of the electric control box 105; on the other hand, it facilitates line connection and data transmission between the electric control box 105 and other components. The body temperature regulating device 103 and the sensor assembly are connected to the electric control box 105. The body temperature regulating device 103 and the sensor assembly are connected to the electric control box 105 through specific interfaces and lines. A two-way data communication and control connection is established between the temperature control module inside the body temperature regulating device 103 and the electric control box 105. The electric control box 105 can send a control signal to the body temperature regulating device 103 according to a preset temperature control strategy or an external input instruction, thereby realizing precise control of the body temperature of the test dummy 100. At the same time, the body temperature regulating device 103 will also feedback its own working status and current temperature data to the electric control box 105 in real time for real-time monitoring and adjustment. The sensor components transmit the collected status data to the socket on the rear side of the electric control box 105 through their respective signal transmission lines. Two quick-plug interfaces are provided on the front side of the electric control box 105 to connect to an external display screen and a power supply. The data processed by the electric control box 105 can be further displayed to the test personnel in an intuitive form through connection with an external display screen, so that they can understand the various status parameters of the test dummy 100 in different test scenarios in real time, providing strong support for subsequent test evaluation and data analysis.

[0077] In some examples, the body temperature regulating device 103 is an electric heating film, which is attached to the back of the back component 106 and the hip component 107. The electric heating film is made of a special conductive material, and its internal conductive circuit is precisely designed to quickly and evenly dissipate heat after power is turned on. When the electric control box 105 sends current to the electric heating film according to the preset temperature parameters or external instructions, the electric heating film starts to work, and the heat generated can be quickly transferred to the dummy body 101, thereby adjusting the surface temperature of the dummy. Since the electric heating film is attached to the back of the back component 106 and the hip component 107, the heat can be conducted more directly and efficiently, reducing the loss of heat during the transfer process. At the same time, this bonding method also makes the combination of the electric heating film and the dummy body 101 more stable, and it is not easy to shift or fall off during the test process, ensuring the stability and reliability of body temperature regulation.

[0078] Figure 6 A schematic diagram of the structure of a counterweight bracket of an embodiment of the present invention is shown. As shown in the figure, in some examples, the back assembly 106 includes a back plate 113 and a counterweight bracket 114, and the counterweight bracket 114 is arranged on the back plate 113, and the counterweight bracket 114 is used to adjust the weight of the test dummy 100. Specifically, the back plate 113 serves as the basic supporting structure of the back assembly 106. The counterweight bracket 114 is arranged on the back plate 113, and is used to flexibly adjust the weight of the test dummy 100. As shown in the figure, the counterweight bracket 114 has a counterweight rod 115 extending to both sides in the horizontal direction. By adding or removing counterweight blocks (weights) of different weights on the counterweight rod 115, the overall weight of the dummy can be accurately changed.

[0079] Figure 7 A schematic structural diagram of a rotating connection member according to an embodiment of the present invention is shown. Figure 8 The following is a schematic diagram showing the structure of a hip fixing seat according to an embodiment of the present invention. Figure 1As shown, in some examples, the test dummy 100 also includes a rotating connector 116 having a continuous bending structure. The hip assembly 107 includes a hip fixing seat 117. The hip fixing seat 117 provides a stable installation position for the electric control box 105. The electric control box 105 is fixed to the hip fixing seat 117 by screws. The hip fixing seat 117 is connected to the back plate 113 through the rotating connector 116. The rotating connector 116 has good rotation flexibility and structural strength. The test dummy 100 adjusts the opening and closing angle between the hip fixing seat 117 and the back plate 113 through the rotating connector 116. In the design and testing process of the zero-gravity seat of the car, it is necessary to simulate the state of the human body in different postures. By adjusting the opening and closing angle between the dummy hip fixing seat 117 and the back plate 113, the dummy can present a posture similar to that of the human body on the zero-gravity seat, thereby more realistically simulating the force, fit and comfort of the human body on the zero-gravity seat of the car.

[0080] In some examples, if the temperature of the test dummy 100 reaches above 37°, the electric control box 105 controls the sweating device 104 to work. After the sweating device 104 receives the instruction from the electric control box 105, the peristaltic pump 109 pumps the pre-mixed simulated sweat into the sponge layer through the hose. The simulated sweat will be evenly distributed in the sponge layer and gradually penetrate into the breathable layer, and finally form an effect similar to human sweating on the surface of the dummy jacket 102.

[0081] Fig. 9 The flowchart of a method for testing a zero-gravity seat of an automobile according to an embodiment of the present invention is shown. The present invention also provides a method for testing a zero-gravity seat of an automobile, using the aforementioned test dummy 100. The test method comprises the following steps:

[0082] S1, placing the test dummy 100 on the automobile zero-gravity seat in the test environment chamber;

[0083] S2, using the rotating connector 116 to adjust the opening and closing angle between the back component 106 and the hip component 107. Through fine adjustment, the back component 106 of the test dummy 100 is made to fit the backrest of the zero-gravity seat of the car to simulate the contact state between the back and the backrest of the human body; at the same time, the hip component 107 of the test dummy 100 is made to fit the seat surface of the zero-gravity seat of the car to ensure that the contact area and pressure distribution are similar to the actual situation of the human body;

[0084] S3, connect the sweating device 104 to the dummy coat 102, and connect the peristaltic pump 109 in the sweating device 104 to the sponge layer of the dummy coat 102 through a hose. During the connection process, it is necessary to ensure that the hose is well sealed to avoid leakage of simulated sweat, so as to ensure that the sweating device 104 can work normally;

[0085] S4, connect the sensor assembly and the temperature regulating device 103 to the electric control box 105;

[0086] S5, adjusting the temperature of the test environment chamber. According to the specific requirements of the test, the temperature of the test environment chamber is accurately adjusted by using the temperature adjustment system in the test environment chamber to simulate the working state of the zero-gravity seat of the car under different climates and usage scenarios;

[0087] S6, adjust the counterweight of the test dummy 100; adjust the counterweight of the test dummy 100 according to the test requirements. By adding or removing counterweights of different weights on the counterweight bracket 114 of the back assembly 106, the overall weight of the test dummy 100 can be accurately changed. The adjustment of the counterweight can simulate the pressure and force of the human body on the zero-gravity seat of the car under different weight conditions, making the test results more universal and representative. When adjusting the counterweight, pay attention to keeping the center of gravity of the dummy balanced to avoid affecting the accuracy of the test due to uneven weight distribution.
