[0028] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-8 As shown, a multi-layer composite warm, windproof and breathable down pants comprises a down pants body 1, which comprises a windproof layer, a breathable layer and a down thermal insulation layer located between the windproof layer and the breathable layer. A protective component is provided on the front of the down pants body 1 at the knee portion, for protecting the knees when the user falls. A trigger component is provided on the portion of the down pants body 1 below the knee, for triggering the protective component to activate when the user falls.

[0031] Among them, the protective assembly includes a skin-fitting plate 2 and a protective plate 3 that fit tightly but not connected. The skin-fitting plate 2 is provided with a number of grooves 4, and the protective plate 3 is provided with a number of limit blocks 6 with limit grooves 5 corresponding to the grooves 4. A No. 1 spring 7 is provided in the groove 4, and the No. 1 spring 7 is provided with an iron clamping block 8 that can be moved in the groove 4 and inserted into the limit groove 5 to limit the limit block 6. An electromagnet 9 is provided in the groove 4 to drive the clamping block 8 to move. A number of No. 2 springs 10 for driving the protective plate 3 to move and a telescopic rod for maintaining the moving direction of the protective plate 3 are provided between the skin-fitting plate 2 and the protective plate 3;

[0032] The trigger assembly includes a shell 11, in which an electrode No. 12 and an electrode No. 2 13 are provided. The electrode No. 12 and the electrode No. 2 13 are both connected to the electromagnet 9 through wires. A power supply is provided between the electrode No. 2 13 and the electromagnet 9. A conductive liquid 14 is provided in the shell 11 for connecting the electrode No. 12 and the electrode No. 2 13 to form a closed loop. The conductive liquid 14 conducts the electrode No. 12 and the electrode No. 2 13 when the down pants body 1 is tilted. When the closed loop is connected, the electromagnet 9 forms a magnetic attraction on the block 8 to move the block 8. The limit block 6 is pulled out of the groove 4 under the drive of the spring No. 2 10, so that the protective plate 3 is separated from the skin-contacting plate 2.

[0033] It should be noted that when the user falls forward, the shell 11 in the trigger assembly tilts, and the conductive liquid 14 in the shell 11 tilts synchronously. When the conductive liquid 14 tilts, the first electrode 12 and the second electrode 13 are connected, so that the electromagnet 9, the power supply, the second electrode 13, the conductive liquid 14, and the first electrode 12 form a complete closed circuit, thereby activating the electromagnet 9. The magnetic attraction generated by the electromagnet 9 acts on the block 8, causing the block 8 to move and the first spring 7 to be squeezed. When the block 8 moves, it is pulled out of the limit slot 5. After the block 8 is pulled out, the limit block 6 is in a free-moving state. Because the second spring 10 is compressed when the skin-contacting plate 2 and the protective plate 3 are in close contact, when the block 8 is pulled out, the second spring 10 drives the protective plate 3 to move away from the skin-contacting plate 2, resulting in a larger distance between the skin-contacting plate 2 and the protective plate 3. When the protective plate 3 contacts the ground, the cushioning effect of the second spring 10 slows the movement of the skin-contacting plate 2, slowing the user's knees and preventing them from colliding with the ground at high speed. When the user stands up, they manually press the stopper 6 into the groove 4. The locking block 8, activated by the first spring 7, automatically enters the stopper slot 5, completing the reset of the protective assembly.

[0034] The skin-contacting plate 2 is provided with a first plate 15, which is equipped with several air cylinders 16. A second plate 17 is provided at the end of the air cylinder 16 away from the first plate 15. The skin-contacting plate 2 is provided with two pulleys 18, and the protective plate 3 is provided with two connecting ropes 19. The end of the connecting rope 19 away from the protective plate 3 passes through the pulleys 18 and is connected to the second plate 17. The down pants body 1 is provided with an air bag 20 at the position of the human coccyx. Tracheas are provided between the air bags 20 and each air cylinder 16, each with a one-way valve inside. The air bags 20 are equipped with exhaust valves for manual exhaust. When the protective plate 3 is away from the skin-contacting plate 2, it pulls the connecting rope 19, causing the connecting rope 19 to pull the second rope to move. The second rope causes the air cylinder 16 to shorten, allowing the gas inside the air cylinder 16 to enter the air bag 20 through the trachea, causing the air bag 20 to expand instantly. When the user falls backward, the air bag 20 expands, protecting the user's coccyx. After use, the gas in the airbag 20 is released through the exhaust valve, and the airbag 20 can be reused without affecting the normal use of the down pants.

[0035] A blocking ring is installed within the housing 11 to prevent the conductive liquid 14 from accidentally triggering the electromagnet 9. This ring blocks contact between the conductive liquid 14 and the first electrode 12 during normal movement, reducing the chance of the protective component being accidentally triggered and improving its effectiveness. When the conductive liquid 14 tilts, it can pass over the blocking ring, ensuring proper triggering of the protective component.

[0036] A third spring 21 is disposed between the second electrode 13 and the housing 11. The force exerted by the third spring 21 on the second electrode 13 causes the second electrode 13 to move upward, and the weight of the conductive liquid 14 causes the second electrode 13 to be squeezed downward. When the housing 11 tilts, the conductive liquid 14 also tilts, reducing the force exerted by the conductive liquid 14 on the second electrode 13. Under the action of the third spring 21, the second electrode 13 gradually approaches the first electrode 12, shortening the distance between the second and first electrodes 13 and 12. As the second electrode 13 moves, it drives the conductive liquid 14 with it, allowing it to contact the first electrode 12 in a shorter time. This effectively improves the trigger assembly's response speed, allowing the protective plate 3 to promptly protect the user.

[0037] A waterproof, breathable membrane is installed within housing 11. This membrane allows gas to pass through, ensuring the normal movement of conductive liquid 14. As the second electrode 13 moves, it pushes the air within housing 11 upward, allowing air to pass through the membrane and enter above housing 11 and first electrode 12. This prevents conductive liquid 14 from passing through the membrane, preventing the gas within housing 11 from affecting its movement and ensuring the normal movement of third spring 21 and second electrode 13. Furthermore, the membrane reduces the chance of liquid leakage within housing 11, ensuring the proper functioning of the trigger assembly.

[0038] The conductive liquid 14 is a sodium chloride solution or a silver nitrate solution.

[0039] Several rollers are provided between the stop block 6 and the stop slot 5 to reduce the pulling force required to disengage the clamping block 8 from the stop block 6. Because the No. 2 spring 10 is subjected to significant compressive force, there is considerable friction between the clamping block 8 and the stop block 6. The electromagnet 9 must generate a significant magnetic attraction to the clamping block 8 in order to move it, which places certain demands on the power of the electromagnet 9. The provision of rollers creates rolling friction with the clamping block 8 during its withdrawal, significantly reducing the pulling force required to move the clamping block 8. This allows the triggering condition of the trigger assembly to be met without requiring significant power from the electromagnet 9, reducing the cost of the down pants and ensuring the proper operation of the trigger assembly.

[0040] The skin contact plate 2 and the protective plate 3 are of arc-shaped structures. The skin contact plate 2 of the arc-shaped structure can be consistent with the outline of the down pants, so as to avoid affecting the aesthetics of the down pants.

[0041] A clamping sleeve 22 is provided on the side of the skin-contact plate 2 away from the protective plate 3 for aligning the knee. The clamping sleeve 22 can limit the knee when the user's knee approaches the skin-contact plate 2, so that the user's knee enters the concave clamping sleeve 22, which can not only provide preliminary protection for the knee, but also prevent a large misalignment between the knee and the skin-contact plate 2, so that the protective component can accurately act on the knee area.

[0042] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
