When the torso temperature is equal to the flow calibration value, the circuit operates normally. When the torso temperature is less than the flow calibration value, the thermosensitive material contracts and becomes smaller, controlling the flow control mechanism to move, and the flow control mechanism controls the size of the flow regulating port. At the same time, the shaft is adjusted to rotate, and the shaft controls the adjustment resistor to rotate, the partial pressure resistance increases, and the cooling intensity decreases.

[0040] C. When the trunk temperature is greater than the flow calibration value, if the temperature is not appropriate after the system is operating normally, adjust the control valve and the circuit flow rate to adjust it to the appropriate temperature;

[0041] D. If the temperature is still not suitable after adjusting the control valve, control the short-circuit switch, short-circuit the regulating resistor, increase the cooling intensity, and adjust to a suitable temperature;

[0042] E. If the temperature inside the suit is still not appropriate after the resistance is adjusted by short circuit, adjust the control valve and then adjust the flow rate of the circuit until the temperature is appropriate.

[0043] The working principle and beneficial effects of the present invention are:

[0044] In the existing technology, protective clothing temperature control systems are mainly of two types: one uses a fixed-flow pump system to provide fixed cooling power; the other uses a system with adjustable working fluid flow and cooling source temperature to provide cooling power allocated on demand. However, these protective clothing microenvironment temperature control systems still have the following problems:

[0045] 1. The fixed cooling power temperature control system provides a fixed flow rate and temperature of working fluid for heat dissipation of the human torso, which cannot well meet the comfortable temperature requirements of different individuals. Under conditions with low torso activity, overcooling may occur, causing human discomfort.

[0046] 2. The temperature control system with adjustable working fluid flow and cold source temperature can meet the individual's needs for different heat dissipation power, but the piping system and control system are complex, which increases the consumption of electricity, resulting in a larger system weight and volume, thereby reducing the wearability of the system.

[0047] For the above reasons, there is a need for a cooling structure that can automatically adjust after detecting human body temperature. At the same time, it is necessary to reduce the use of internal circuit components, reduce the load on the power supply, and thus reduce the overall weight of the equipment, so as to achieve a lightweight design of the equipment. In order to solve the above problems, a thermosensitive material that can sense temperature is designed to achieve corresponding physical transformation after temperature detection, achieve automatic adjustment of temperature, and then achieve temperature sensing by the mechanical structure. The converted physical change is converted into a displacement change that can realize the function through the displacement amplification mechanism, thereby achieving temperature regulation. The temperature control system in the existing technology needs to detect the temperature through electronic components and then feedback the signal to the central control position. After the calculation of the central control, the signal is fed back and the adjustment is made through the signal system. The whole system requires precise electronic components and computing power to calculate the temperature, which puts a huge burden on the power supply of the protective suit. At the same time, due to the precise electronic components, the components may be damaged due to accidents during use, thereby increasing maintenance costs. Compared with the idea of this solution, it requires more costs and a more demanding use environment.

[0048] In order to solve the above-mentioned related problems, the present invention designs an adaptive thermal management system for protective clothing. Specifically, a torso cooling device is provided in the protective clothing. The operator needs to put on the torso cooling device before entering the protective outer garment. The temperature is adjusted by an automatic temperature control device on the protective outer garment. The automatic temperature control device is implemented by an internal heat dissipation device and a temperature-sensing displacement conversion mechanism. Specifically, the second cooling cavity in the heat dissipation device is connected to the first cooling cavity of the torso cooling device to realize the circulation of the internal cooling medium and cool the human body. The temperature of the cooling medium flowing into the second cooling cavity is sensed by the thermosensitive material on the temperature-sensing displacement conversion mechanism, and the temperature inside the protective clothing is thereby determined. According to a pre-set system flow calibration value, the thermosensitive material controls the displacement amplification mechanism, so that the displacement of the thermosensitive material caused by the temperature change is further amplified by the displacement amplification mechanism. The amplified displacement is applied to the flow control mechanism by the displacement amplification mechanism to realize the left and right movement of the flow control mechanism, thereby changing the size of the flow adjustment area and the circulation speed of the cooling medium, so that the temperature inside the protective clothing is maintained within the system flow calibration value range through feedback.

[0049] This solution can control the temperature inside the protective suit through the mechanical structure, and can make corresponding adjustments to the changes in the internal temperature in real time, reducing the burden on the power supply of the protective suit. At the same time, due to the adjustment of the mechanical structure, it has a certain adaptability to some collisions. Compared with electronic components, this device can adapt to more usage environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0060] like Figures 1 to 7 As shown, this embodiment proposes

[0061] An adaptive thermal management system for protective clothing, comprising a protective outer garment having a sealed cavity, comprising

[0062] The trunk cooling device 1 has a first cooling cavity 2, which is arranged in a sealed cavity. The trunk cooling device 1 is worn by an operator. The first cooling cavity 2 is used to store a cooling medium.

[0063] The automatic temperature regulating device 3 is provided on the protective outer garment and includes:

[0064] The heat dissipation device 4 has a second cooling cavity 5, which is connected to the first cooling cavity 2 and has a flow regulating area 6.

[0065] The temperature sensing displacement conversion mechanism 7 is provided on the heat dissipation device 4 and includes

[0066] The heat-sensitive material 8 is provided on the heat dissipation device 4 and is used to expand or contract after sensing the temperature in the second cooling cavity 5.

[0067] The displacement amplifying mechanism 9 is provided on the heat dissipating device 4 and is used to amplify the displacement of the heat-sensitive material 8.

[0068] The flow control mechanism 10 is slidingly arranged in the flow regulating area 6 , and the displacement amplification mechanism 9 is used to control the sliding of the flow control mechanism 10 , and the flow control mechanism 10 is used to control the size of the flow regulating area 6 .

[0069] In the existing technology, protective clothing temperature control systems are mainly of two types: one uses a fixed-flow pump system to provide fixed cooling power; the other uses a system with adjustable working fluid flow and cooling source temperature to provide cooling power allocated on demand. However, these protective clothing microenvironment temperature control systems still have the following problems:

[0070] 1. The fixed cooling power temperature control system provides a fixed flow rate and temperature of working fluid for heat dissipation of the human torso, which cannot well meet the comfortable temperature requirements of different individuals. Under conditions with low torso activity, overcooling may occur, causing human discomfort.

[0071] 2. The temperature control system with adjustable working fluid flow and cooling source 30 temperature can meet the individual's needs for different heat dissipation power, but the piping system and control system are complex, which increases the power consumption, resulting in a larger system weight and volume, thereby reducing the wearability of the system.

[0072] For the above reasons, a cooling structure is needed that can automatically adjust the temperature after detecting the human body temperature. At the same time, it is necessary to reduce the use of internal circuit components, reduce the load of the power supply 33, and thus reduce the overall weight of the device, so as to achieve a lightweight design of the device. To solve the above problems, a thermosensitive material 8 that can sense temperature is designed to achieve corresponding physical transformation after temperature detection, realize automatic temperature adjustment, and then realize the mechanical structure sensing temperature. The converted physical change is converted into a displacement change that can realize the function through the displacement amplification mechanism 9, thereby realizing temperature regulation. The temperature control system in the existing technology needs to detect the temperature through electronic components and then feedback the signal to the central control position. After the central control calculates, the signal is fed back again, and the signal system makes adjustments. The whole system requires precise electronic components and computing power to calculate the temperature, which places a huge burden on the power supply 33 on the protective suit. At the same time, due to the precision of the electronic components, the components may be damaged due to accidents during use, thereby increasing maintenance costs. Compared with the idea of this solution, it requires more costs and a more demanding use environment.

[0073] In this embodiment, in order to solve the above-mentioned related problems, an adaptive thermal management system of protective clothing is designed. Specifically, by setting a torso cooling device 1 in the protective clothing, the operator needs to wear the torso cooling device 1 before entering the protective outer clothing, and the temperature is adjusted by the automatic temperature control device 3 on the protective outer clothing. The automatic temperature control device 3 is realized by the internal heat dissipation device 4 and the temperature-sensing displacement conversion mechanism 7. Specifically, the second cooling cavity 5 in the heat dissipation device 4 is connected to the first cooling cavity 2 of the torso cooling device 1 to realize the circulation of the internal cooling medium and the cooling of the human body, and then the temperature is adjusted by the temperature-sensing displacement conversion mechanism 7. The thermosensitive material 8 senses the temperature of the cooling medium flowing into the second cooling cavity 5, and then determines the temperature inside the protective suit. Through the pre-set system flow calibration value, the thermosensitive material 8 controls the displacement amplification mechanism 9, so that the displacement of the thermosensitive material 8 caused by the temperature change is further amplified by the displacement amplification mechanism 9. The amplified displacement is applied to the flow control mechanism 10 through the displacement amplification mechanism 9, realizing the left and right movement of the flow control mechanism 10, thereby changing the size of the flow regulation area 6 and the circulation speed of the cooling medium, so that the temperature inside the protective suit is maintained within the system flow calibration value range through feedback.

[0074] This solution can achieve temperature control inside the protective suit through a mechanical structure, and can make corresponding adjustments to changes in the internal temperature in real time, reducing the burden on the power supply 33 on the protective suit. At the same time, due to the adjustment of the mechanical structure, it has a certain adaptability to some collisions. Compared with electronic components, this device can adapt to more usage environments.

[0075] Furthermore, the heat dissipation device 4 has a first mounting groove 11, and the temperature-sensing displacement conversion mechanism 7 also includes

[0076] The first sliding rack 12 is slidably arranged in the first mounting groove 11. The heat-sensitive material 8 is located in the first mounting groove 11 and is connected to the first sliding rack 12. The heat-sensitive material 8 drives the first sliding rack 12 to slide after sensing the temperature. The first sliding rack 12 is coordinated with the displacement amplification mechanism 9.

[0077] The first elastic member 13 has one end disposed on the inner wall of the first mounting groove 11 and the other end disposed on the first sliding rack 12 , and is used to provide a force to push the first sliding rack 12 away from the inner wall of the first mounting groove 11 .

[0078] In this embodiment, in order to better transmit the displacement generated by the heat-sensitive material 8 to the displacement amplification mechanism 9, a first sliding rack 12 and a first elastic member 13 are added. Specifically, a first mounting groove 11 is provided on the heat dissipation device 4, and the first sliding rack 12 is provided in the first mounting groove 11. The heat-sensitive material 8 is located in the first mounting groove 11, and the heat-sensitive material 8 is connected to the first sliding rack 12. After the heat-sensitive material 8 senses the temperature, it drives the first sliding rack 12 to slide. The first sliding rack 12 is cooperated with the displacement amplification mechanism 9. One end of the first elastic member 13 is provided on the inner wall of the first mounting groove 11, and the other end is provided on the first sliding rack 12, which is used to provide a force for the first sliding rack 12 to move away from the inner wall of the first mounting groove 11, thereby realizing the resetting of the first sliding rack 12. Through this solution, the displacement changes generated by the heat-sensitive material 8 can be better transmitted to the displacement amplification mechanism 9, thereby further improving the stability of the equipment.

[0079] Furthermore, the displacement amplification mechanism 9 includes

[0080] The first gear 14 is rotatably mounted on the heat sink 4 and meshes with the first sliding rack 12.

[0081] The second gear 15 is rotatably mounted on the heat sink 4 and meshes with the first gear 14.

[0082] The third gear 16 is coaxial with the second gear 15 and is rotatably arranged on the heat dissipation device 4. The third gear 16 rotates with the second gear 15. The diameter of the third gear 16 is larger than the diameter of the second gear 15.

[0083] The second sliding rack 17 is provided on the flow control mechanism 10 and meshes with the third gear 16 to drive the flow control mechanism 10 to slide.

[0084] In this embodiment, a displacement amplification mechanism 9 is specifically refined. Specifically, a first gear 14 is provided on the heat dissipation device 4 to cooperate with the first sliding rack 12. After the first sliding rack 12 is displaced, the sliding displacement of the first sliding rack 12 is converted into the rotation of the first gear 14 through the meshing setting of the gear rack. Then, by providing a second gear 15, the rotation of the first gear 14 is transmitted to the second gear 15. The second gear 15 drives the shaft to rotate, and the shaft drives the third gear 16 to rotate. Therefore, the rotation can be transmitted to the third gear 16 through the second gear 15. Since the third gear 1 The diameter of gear 6 is larger than that of second gear 15, so when the third gear 16 rotates at the same angle as the second gear 15, it can amplify the rotational displacement, thereby amplifying the rotation of the first gear 14. The amplified rotation is converted by the third gear 16 and transmitted to the second sliding rack 17 matched with the third gear 16, so that the rotational displacement is converted into a sliding displacement, thereby realizing the overall displacement conversion process, so that the small displacement generated by the heat-sensitive material 8 is converted into a large displacement that can control the flow control mechanism 10 to adjust the flow rate. This solution can further improve the practicality and structural integrity of the equipment.

[0085] Furthermore, one end of the heat-sensitive material 8 is attached to the outer wall of the second cooling cavity 5, and further includes

[0086] The disturbance plate 18 is disposed in the second cooling cavity 5 and is located beside the heat-sensitive material 8 .

[0087] In this embodiment, in order to further increase the stability of the thermosensitive material 8, a disturbance plate 18 is provided in the second cooling cavity 5. The disturbance plate 18 is located near the thermosensitive material 8. The flow state of the cooling medium near the thermosensitive material 8 is changed by the disturbance plate 18, thereby increasing the sensitivity of the thermosensitive material 8 to temperature sensing. At the same time, the demand for thermosensitive material 8 can be reduced, so that the device can realize temperature detection through a small amount of thermosensitive material 8, further improving the practicality of the device and reducing the cost of the device.

[0088] Furthermore, the flow control mechanism 10 includes

[0089] The sliding member 19 is slidably disposed in the flow regulating area 6, dividing the flow regulating area 6 into a regulating cavity 20 and a flow regulating port 21. The regulating cavity 20 has a through hole 22 communicating with the outside. The second sliding rack 17 is disposed on the sliding member 19. After the sliding member 19 slides, the size of the flow regulating port 21 is controlled.

[0090] The preset adjustment component 23 is sealed and arranged at the through hole 22 and is used to adjust the initial position of the sliding member 19.

[0091] In this embodiment, a flow control mechanism 10 is designed to enable the device to better adjust the preset value. Specifically, a slider 19 is provided within the flow adjustment area 6, and the sliding of the slider 19 is controlled by a second sliding rack 17. After the slider 19 slides, the size of the flow adjustment port 21 is adjusted. A preset adjustment component 23 is provided on the slider 19. By adjusting the preset adjustment component 23, the initial position of the slider 19 is set to set the system flow calibration value. After the setting is completed, the displacement amplification mechanism 9 is installed in the specified position. This solution makes it easier to set the system flow calibration value, further improving the practicality of the device.

[0092] Furthermore, the preset adjustment component 23 includes

[0093] The locking member 24 is sealed on the through hole 22.

[0094] The adjusting member 25 passes through the locking member 24 and is threadedly connected to the locking member 24 . One end of the adjusting member 25 is disposed on the sliding member 19 .

[0095] The second elastic member 26 is connected to the adjusting member 25 and the sliding member 19 through the second elastic member 26. One end of the second elastic member 26 is set on the adjusting member 25, and the other end is set on the sliding member 19, which is used to provide a force for the second elastic member 26 to move closer to or away from the adjusting member 25.

[0096] In this embodiment, a preset adjustment component 23 is specifically refined, specifically including a locking member 24 and an adjusting member 25. The locking member 24 is sealed on the through hole 22 to prevent the internal cooling medium from flowing out, and then the adjusting member 25 is passed through the locking member 24 through a threaded connection, and the end portion is set on the sliding member 19. The initial position of the sliding member 19 is moved by rotating the adjusting member 25. In order to achieve two-way adjustment of the flow rate, the sliding member 19 and the adjusting member 25 can be connected by a second elastic member 26 to reduce the internal rigid connection. At the same time, when the displacement amplification mechanism 9 is adjusted, the second elastic member 26 can play a better buffering role. At the same time, the sliding member 19 has a through hole connecting the adjustment cavity 20 and the flow adjustment port 21. The elastic force provided by the second elastic member 26 enables the sliding member 19 to move stably. The connection through the through hole can reduce the force brought by the cooling medium that the sliding member 19 needs to overcome when moving, making the sliding smoother and further improving the service life of the equipment.

[0097] Furthermore, the end 27 of the sliding member 19 is a tapered structure, and the cross-sectional area gradually decreases in the direction toward the flow regulating port 21. The end 27 has a groove 28. The preset regulating assembly 23 also includes

[0098] The third elastic member 29 has one end disposed on the inner wall of the flow regulating port 21 and the other end disposed at the bottom of the groove 28 , and is used to provide a force for the sliding member 19 to move closer to or away from the inner wall of the flow regulating port 21 .

[0099] In this embodiment, in order to make the flow regulation smoother, a conical structure is provided at the end 27 of the sliding member 19, and the cross-sectional area of the conical structure gradually decreases in the direction toward the flow regulating port 21. A groove 28 is provided on the end 27 of the sliding member 19, and one end of the third elastic member 29 is provided on the inner wall of the flow regulating port 21, and the other end is provided at the bottom of the groove 28, which is used to provide a force for the sliding member 19 to approach or move away from the inner wall of the flow regulating port 21, thereby increasing the buffering capacity and making the sliding member 19 more stable during use, further improving the stability of the equipment.

[0100] Furthermore, the automatic temperature control device 3 also includes

[0101] The cold source 30 is provided on the heat sink 4 and is located on one side of the second cooling cavity 5, and is used for heat exchange treatment of the second cooling cavity 5.

[0102] The regulating resistor 31 is set on the heat sink 4.

[0103] The adjusting shaft 32 is rotatably arranged on the heat dissipation device 4, one end of which is engaged with the second gear 15, and the other end of which is arranged on the adjusting resistor 31 for adjusting the resistance value of the adjusting resistor 31.

[0104] The power supply 33 is provided on the heat sink 4 to provide energy for the cold source 30 and the regulating resistor 31 .

[0105] In this embodiment, a cooling structure is specifically refined, specifically, a cold source 30 is cooperated with the heat sink 4, and the cooling medium in the heat sink 4 is cooled by the cold source 30 to achieve the function of cooling and perform heat exchange treatment. An adjustment resistor 31 and an adjustment shaft 32 are also provided on the heat sink 4. The adjustment shaft 32 cooperates with the second gear 15 to generate a rotational displacement to control the resistance value of the adjustment resistor 31, thereby achieving dynamic adjustment, further increasing the ability of the device to automatically adjust the temperature, and also including a power supply 33 for controlling the cold source 30. Since the electronic components are reduced, the service life of the power supply 33 is further increased and the usage intensity is reduced.

[0106] Furthermore, it also includes

[0107] The control valve 34 is provided on the connecting pipeline between the first cooling cavity 2 and the second cooling cavity 5 .

[0108] In this embodiment, in order to enable the device to be better adjusted, a control valve 34 is provided that directly connects the first cooling cavity 2 and the second cooling cavity 5. The control valve 34 can adjust the flow of the cooling medium in the automatic temperature control device 3 by adjusting the flow between the first cooling cavity 2 and the second cooling cavity 5, so that the device has better adjustability and further improves the practicality of the device.

[0109] A method for using an adaptive thermal management system for protective clothing, including an adaptive thermal management system for protective clothing, further comprising the following steps:

[0110] A.
