The second protective sheath 120 is sleeved outside the first flexible buffer layer 110, and the first flexible buffer layer 110 and the second protective sheath 120 are fixed to each other by sewing or bonding. One end of the first hook and loop fastener tape 130 is fixed on the second protective sheath 120, and the other end is a free end.

In this embodiment, the first flexible buffer layer 110 is rectangular or square in shape in the unfolded state, when it is needed to be worn, the first flexible buffer layer 110 and the second protective sheath 120 are curled to cover the thigh, and the free end of the first hook and loop fastener tape 130 is wound around the outside of the second protective sheath 120 and is adhesively connected to the belt body, so that the upper wearing portion 100 is bound and fixed on the thigh, and the wearing on the upper portion is completed.

In this embodiment, the first flexible buffer layer 110 may be a sponge layer; the second protective sheath 120 may be a cloth sheath, such as a wear-resistant cloth. The upper wearing part 100 is designed into a structure of the first flexible buffer layer 110 and the second protective sleeve 120 sleeved outside the first flexible buffer layer 110, so that the upper wearing part is bound on the thigh when in use, and can protect the thigh when in the training of crossing a short wall, so as to prevent the thigh from being bruised or scratched; in addition, by adopting the hook and loop tape as the fixing member, the fixing and releasing of the upper wearing portion 100 can be facilitated, thereby realizing the quick wearing and taking off.

Further, in some embodiments, there may be a plurality of first hook and loop fastener tapes 130, for example, two first hook and loop fastener tapes 130 may be provided, one on the end of the second protective sheath 120 near the protecting portion 200 and the other on the end of the second protective sheath 120 far from the protecting portion 200. So that the upper wearing portion 100 is more securely and stably worn on the thighs as shown in fig. 7.

As shown in fig. 4, the protection part 200 may include an elastic base layer 210, an elastic air bag 220 disposed on the elastic base layer 210, and a one-way air valve 230 disposed on the elastic air bag 220.

In this embodiment, the elastic bottom layer 210 may be a sponge layer or a silicone layer. The elastic bladder 220 may be a silicone bladder or a rubber bladder, so that it can be restored to its original state after being deformed. For example, the elastic airbag 220 may be disposed on the elastic bottom layer 210 by bonding or sewing; the elastic bladder 220 may also be formed on the elastic base layer 210 in an integrally molded manner.

Further, the protection part 200 further includes a first protection cover 260. In this embodiment, the first protective sheath 260 may be a cloth sheath. The first protective sheath 260 is disposed over the elastic base layer 210 and the elastic bladder 220 and fixed to each other by sewing or bonding. And one end of the one-way valve 230 communicates with the outside through the first protection cap 260.

Further, in some embodiments, as shown in fig. 4, an arc portion is disposed in the middle of the elastic bottom layer 210, so that the arc portion can fit over the knee when worn. The elastic balloon 220 is disposed on the arc portion.

In this embodiment, as shown in fig. 5, the check valve 230 may include a valve body and a valve core. Wherein the valve body comprises an annular housing 241. An upper air passage 242 and a lower air passage 243 are provided in the annular housing 241, and the diameter of the upper air passage 242 is smaller than that of the lower air passage 243, so that a stepped air passage is formed in the annular housing 241. Also, a perforated baffle 244 is provided in the lower air duct 243. The valve core comprises a guide post 251 and a silicon membrane sheet 252. A silicone membrane 252 is placed in the space between the hollowed-out baffle 244 and the upper airway 242. The diameter of the silica gel membrane 252 is smaller than the diameter of the hollow baffle 244 and larger than the diameter of the upper air duct 242. The lower end of the guide post 251 is vertically connected to the middle of the silica gel membrane 252. The upper end of the guide post 251 passes through the upper air passage 242 and protrudes from the top end of the upper air passage 242. A stopper 253 is provided at the upper end of the guide column 251, and the guide column 251 has a diameter smaller than that of the upper air passage 242 so that the silicone diaphragm 252 can move in the axial direction of the lower air passage 243. Further, in a natural state, the elastic air bag 220 is in an inflated state, and when the elastic air bag 220 is extruded, the one-way air valve 230 is closed, so that the elastic air bag 220 is formed into a closed safety air bag and only slightly deforms when being impacted, and the knee is protected; when the elastic air bag 220 is restored to the natural state from the deformed state, the one-way air valve 230 is opened, and the external air is sucked into the elastic air bag 220 to restore the elastic air bag, so that the trouble of manual inflation is avoided.

Specifically, when the elastic airbag 220 is squeezed, the gas in the airbag is discharged outwards through the hollow part on the hollow baffle 244, so that the silicone membrane 252 is pressed and moves towards the upper air passage 242, and because the diameter of the silicone membrane 252 is larger than that of the upper air passage 242, when the silicone membrane 252 moves to the bottom of the upper air passage 242, the silicone membrane 252 can seal the upper air passage 242, so that the gas in the airbag is prevented from being discharged, the elastic airbag 220 is formed into a closed airbag, and only slightly deforms when being impacted, so that the knee is protected; when the elastic air bag 220 is restored to the natural state from the deformation state, the air bag inhales air inwards, the silicone membrane sheet 252 is restored to the hollowed-out baffle 244 from the bottom of the upper air passage 242 under the air pressure of external air, and the diameter of the silicone membrane sheet 252 is smaller than that of the hollowed-out baffle 244, so that the external air can pass through the hollowed-out baffle 244 from the upper air passage 242 to enter the lower air passage 243 and further enter the air bag, so that the air bag is restored to the original state, and the trouble of manual inflation can be omitted because the elastic air bag 220 can be inflated automatically.

Wherein, the upper end of the protection part 200 is connected with the upper wearing part 100 through the first flexible connecting part 400. Illustratively, one end of the first flexible connecting portion 400 is fixedly connected to the upper end of the elastic bottom layer 210, and the other end is fixedly connected to the first flexible buffer layer 110.
