[0030] Example 1

[0031] refer to Figures 1 to 6 A protective gear 10, comprising:

[0032] Protective gear body 1, which is used to wrap and protect body parts;

[0033] The first airbag 2 is attached to the surface of the protective gear body 1.

[0034] With the above structure, by setting the first airbag 2 on the surface of the protective gear body 1, when the protective gear body 1 is wrapped around the body, the first airbag 2 can apply flexible cushioning to the body during use, effectively disperse external force impact, reduce pressure and damage to the body joints, and at the same time improve the fit and comfort of wearing.

[0035] In this embodiment, the first airbag 2 and the protective gear body 1 can be connected by means of sewing, heat fusion, adhesive, Velcro, magnetic attraction, buckle, etc., which are not limited here.

[0036] In this embodiment, the protective gear body 1 has an inner surface 11 that acts on the body part and an outer surface 12 opposite to the inner surface 11, with the first airbag 2 connected to the inner surface 11. Through this structure, the first airbag 2 acts directly on one side of the body part. Because the airbag is in close contact with the body surface, it can form a flexible buffer layer when subjected to external force, reducing the direct transmission of external impact to the body, decreasing local pressure, and improving overall wearing comfort. Compared to traditional rigid or soft lining structures, the airbag structure is softer and reduces pressure, effectively reducing friction discomfort and skin irritation caused by prolonged wear.

[0037] In this embodiment, the first airbag 2 has a first inflation chamber 21 and a first air nozzle assembly 3. The protective gear body 1 has a first mounting hole 13 communicating with the first inflation chamber 21. The first air nozzle assembly 3 extends from the inner surface 11 through the first mounting hole 13 to the outer surface 12. With the above structure, the first air nozzle assembly 3 extends to the outer surface 12 of the protective gear body 1, allowing the user to conveniently inflate or deflate the airbag while wearing it, improving ease of use and flexibility.

[0038] Furthermore, the first air nozzle assembly 3 includes a first air nozzle housing 31, a first sealing plug 32, and a first return spring 33. The first air nozzle housing 31 has a first airflow chamber 311, a first inflation port 312 communicating with the first airflow chamber 311, and a first air inlet 313. A first limiting ring 314 protrudes inward at the first inflation port 312. The first sealing plug 32 and the first return spring 33 are located inside the first airflow chamber 311, and one end of the first return spring 33 is sleeved and pressed against the first sealing plug. 32. The other end of the first return spring 33 is pressed against the bottom of the first inflation chamber 21. The first sealing plug 32 is used to press against the first limiting ring 314 to seal the first air inlet 313. The first air inlet 313 is connected to the first inflation chamber 21. When the first airbag 2 is inflated, the first return spring 33 is squeezed, the first sealing plug 32 is disengaged from the first limiting ring 314, and the airflow passes through the first inflation port 312, the first airflow chamber 311, the first air inlet 313 and the first inflation chamber 21 in sequence.

[0039] With the above structure, the first sealing plug 32 can automatically press against the first limiting ring 314 under the elastic force of the first return spring 33, thereby sealing the first air inlet 313, effectively preventing air leakage from the airbag in use or when it is not inflated, and improving sealing reliability and safety. When an external inflation device is applied, the sealing plug is squeezed out of the first limiting ring 314, and the airflow quickly enters the first inflation chamber 21, achieving rapid inflation. The structure is simple but the airflow is smooth, improving operational efficiency.

[0040] In this embodiment, the protective gear body 1 is a flexible protective gear body 1. With the above structure, the flexible protective gear body 1 can fit snugly around the body parts.

[0041] In this embodiment, the protective gear body 1 is provided with a first support member 4, which is disposed opposite to the first airbag 2. Further, the protective gear body 1 is provided with a second support member 41, which is disposed opposite to the first airbag 2; the first support member 4 and the second support member 41 have different lengths. Further, the first support member 4 and the second support member 41 are arranged laterally from the middle of the protective gear body 1 toward the side of the protective gear body 1, and the length of the first support member 4 is greater than the length of the second support member 41.

[0042] Furthermore, the protective gear body 1 is also provided with a fifth support member 42. The first support member 4, the second support member 41 and the fifth support member 42 are arranged horizontally from the middle of the protective gear body 1 toward the side of the protective gear body 1, and the lengths of the first support member 4, the second support member 41 and the fifth support member 42 gradually decrease.

[0043] Specifically, in this embodiment, both the first support member 4 and the second support member 41 are metal supports; both the first support member 4 and the second support member 41 are steel sheets 43; the length of the first support member 4 is greater than the length of the second support member 41; the length of the steel sheet 43 ranges from 4mm to 250mm; the width of the steel sheet 43 ranges from 1mm to 300mm; and the thickness of the steel sheet 43 ranges from 0.5mm to 30mm.

[0045] By incorporating steel plates 43 within the flexible protective gear body 1, the support capacity of the protective gear 10 in specific areas can be effectively enhanced. This allows the protective gear 10 to maintain structural stability and shape retention in key areas while flexibly conforming to the body, preventing structural deformation or instability caused by airbag inflation. The steel plates 43 are arranged laterally in sequence with varying lengths, creating a gradient support structure for the protective gear 10. This helps reduce lateral pressure while ensuring support strength.

[0046] In this embodiment, the outer surface 12 of the protective gear body 1 is provided with a protruding first wrapping part 5, which corresponds to the first airbag 2. The first wrapping part 5 has a first wrapping cavity 51, in which the first support member 4, the second support member 41, and the fifth support member 42 are all disposed. Through the above structure, the protruding shape of the first wrapping part 5 avoids direct contact between the support member and the human body, avoids pressure or irritation of the skin or soft tissue by hard materials, and improves the comfort and safety of wearing.

[0047] In this embodiment, the protective gear 10 also includes a second airbag 6, which is laterally distributed on the inner surface 11 along with the first airbag 2; the first airbag 2 and the second airbag 6 have the same shape and are symmetrically arranged.

The second wrapping part 8 has a second wrapping cavity 81. The third support member 7, the fourth support member 71, and the sixth support member 72 are all arranged in the second wrapping cavity 81. The first wrapping part 5 and the second wrapping part 8 are laterally distributed on the outer surface 12. The first wrapping part 5 and the second wrapping part 8 have the same shape and are symmetrically arranged.

[0049] In this embodiment, the second airbag 6 has a second inflation chamber 61 and a second air nozzle assembly 9. The protective gear body 1 has a second mounting hole 14 communicating with the second inflation chamber 61. The second air nozzle assembly 9 extends from the inner surface 11 through the second mounting hole 14 to the outer surface 12. With the above structure, the user can conveniently inflate or deflate the airbag while wearing it, improving the convenience and flexibility of use.

[0050] In this embodiment, the second air nozzle assembly 9 includes a second air nozzle housing 91, a second sealing plug 92, and a second return spring 93. The second air nozzle housing 91 has a second airflow cavity 911, a second inflation port 912, and a second air inlet 913 communicating with the second airflow cavity 911. A second limiting ring 914 protrudes inward at the second inflation port 912. The second sealing plug 92 and the second return spring 93 are located inside the second airflow cavity 911, and one end of the second return spring 93 is sleeved and pressed against the second sealing plug. 92. The other end of the second return spring 93 abuts against the bottom of the second inflation chamber 61. The second sealing plug 92 abuts against the second limiting ring 914 to seal the second air inlet 913. The second air inlet 913 is connected to the second inflation chamber 61. When the second airbag 6 is inflated, the second return spring 93 is compressed, and the second sealing plug 92 disengages from the second limiting ring 914. The airflow passes sequentially through the second inflation port 912, the second airflow chamber 911, the second air inlet 913, and the second inflation chamber 61. Through the above structure, similarly, the second sealing plug 92 can automatically abut against the second limiting ring 914 under the elastic force of the second return spring 93, thereby sealing the second air inlet 913, effectively preventing air leakage in the airbag during use or when it is not inflated, and improving sealing reliability and safety. When an external inflation device is applied, the sealing plug is dislodged from the second limiting ring 914 under external pressure, and the airflow quickly enters the second inflation chamber 61, achieving rapid inflation. The structure is simple but the airflow is smooth, improving operational efficiency.

[0051] In this embodiment, the protective gear body 1 is also provided with a pressure band 50. When the protective gear body 1 wraps around and protects the body parts, the pressure band 50 is wrapped around the outer surface of the protective gear body 1 in a circumferential direction. The length of the pressure band 50 is in the range of 350cm-500cm. Preferably, the length of the pressure band 50 is 435mm.

[0052] Through the above structure, the pressure belt 50 achieves tight fixation of the protective gear body 1 by circumferential winding, preventing the protective gear 10 from shifting or sliding during movement or activity, and ensuring the continuous and stable protective effect.

[0053] In this embodiment, the brace 10 serves as a knee brace to wrap and protect the leg, and the first airbag 2 covers and acts on the medial and lateral sides of the leg. Specifically, the first airbag 2 covers and acts on the medial and lateral sides of the femoral condyle.

[0080] In this embodiment, the brace 10 serves as a knee brace to wrap and protect the leg, and the first airbag 2 covers and acts on the medial and lateral sides of the leg. Specifically, the first airbag 2 covers and acts on the medial and lateral sides of the femoral condyle. Through this structure, the first airbag 2 covers the medial and lateral sides of the femoral condyle, effectively buffering and dispersing the impact force from the outside, reducing the risk of injury to the knee joint, and improving the protective performance of the knee brace. By protecting and supporting the femoral condyle, it promotes the functional recovery of the knee joint during injury or rehabilitation, making it suitable for rehabilitation training and daily protection.

[0081] In this embodiment, the knee brace also has a through hole 17 located between the first airbag 2 and the second airbag 6. A ring 171 protrudes outward in the circumferential direction of the through hole. Through the above structure, the presence of the through hole 17 allows the knee brace to maintain protection while reducing obstruction in the middle part of the knee and improving the freedom of joint movement.

[0082] In this embodiment, a third elastic band 18 and a fourth elastic band 19 are respectively provided on the upper and lower sides of one side of the protective gear body 1. The tail ends of the third elastic band 18 and the fourth elastic band 19 have Velcro hooks. In use, the knee brace is put on the knee, so that the first airbag 2 and the second airbag 6 cover the femoral condyles on the inner and outer sides of the knee respectively. The third elastic band and the fourth elastic band are wrapped around the periphery and attached to the outer wall of the protective gear body 1 with Velcro. Then, the airbags are inflated by the flexible air cylinder 20 or the electric air pump to provide cushioning and support. After exercise or activity, the elastic bands are loosened and the airbag gas is released, and the protective gear 10 can be easily removed.

[0083] In this embodiment, the length of the first airbag 2 ranges from 5cm to 17cm; the width of the first airbag 2 ranges from 8cm to 15cm; and the area covered by the first airbag 2 on the protective gear body 1 ranges from 85cm. 2 -182cm 2 The area of ​​the first airbag 2 covering the surface of the protective gear body 1 is in the range of 0.23-0.93; when the first airbag 2 is inflated, the thickness of the first airbag 2 is in the range of 2cm-5cm, and the volume of the first inflation chamber 21 is in the range of 80cm³. 3 -1445cm 3 When the first airbag 2 is in the deflated state, the thickness of the first airbag 2 ranges from 0.5cm to 2cm; the length of the protective gear body 1 ranges from 35cm to 80cm; the width of the protective gear body 1 ranges from 15cm to 40cm; the first airbag 2 is provided with a dividing indentation 22, and the width of the dividing indentation 22 ranges from 0.7cm to 1cm.

[0089] With the above structure, during use, by continuously squeezing and pressing the inflation valve 401 with your fingers, the third sealing plug 4022 and the third return spring 4023 are compressed under the force of the gas. The gas can flow into the first inflation chamber 21 through the third inflation port 4025, the third airflow chamber 4024, and the third air inlet 4026. The fourth sealing plug 4032 and the fourth return spring 4033 are compressed under the force of the gas. The gas can flow into the second inflation chamber 61 through the fourth inflation port 4035, the fourth airflow chamber 4034, and the fourth air inlet 4036. When the squeezing and pressing of the inflation valve 401 is stopped, the third return spring 4023 and the fourth return spring 4033 rebound, so that the third sealing plug 4022 and the fourth sealing plug 4032 continue to press and seal the third inflation port 4025 and the fourth inflation port 4035, thereby completing the inflation of the protective gear body. The operation is simple and greatly improves the portability of inflation.
