[0034] Reference below Figures 1 to 8 A protective gear 100 according to an embodiment of the present invention is described.

[0035] like Figure 1 and 2 As shown, the protective gear 100 according to the embodiment of the present invention includes an upper fixing member 200 , a knee pad 300 , a lower fixing member 400 and a linkage device 500 .

[0036] like Figure 1 and 2 As shown, the upper fixing member 200, the knee pad 300 and the lower fixing member 400 are rotatably connected in sequence, and the linkage device 500 is used to realize the linkage between the knee pad 300 and the upper fixing member 200, and the linkage between the knee pad 300 and the lower fixing member 400, wherein the rotation center line of the upper fixing member 200 is parallel to the rotation center line of the lower fixing member 400.

[0037] The upper fixing part 200 is fixedly connected to the thigh, the lower fixing part 400 is fixedly connected to the calf, and the knee guard 300 covers the middle of the knee. By rotating the upper fixing part 200 and the lower fixing part 400, the angle between the upper fixing part 200 and the lower fixing part 400 can be changed to different sizes. When the knee is bent, the knee will push the knee guard 300 forward, and the upper fixing part 200 and the lower fixing part 400 will rotate backward with the thigh and the calf. At this time, under the action of the linkage device 500, the knee guard 300 simultaneously drives the upper fixing part 200 and the lower fixing part 400 to rotate towards each other, so that the upper fixing part 200 and the lower fixing part 400 rotate faster and adapt to the bending angle of the knee more quickly.

[0038] In the protective gear 100 of the embodiment of the present invention, the upper fixing member 200, the lower fixing member 400 and the knee pad 300 are connected by rotation, so that the protective gear 100 can be bent at multiple angles more flexibly. In addition, when the knee is bent, the knee drives the knee pad 300 to move. Under the action of the linkage device 500, the knee pad 300 drives the upper fixing member 200 and the lower fixing member 400 to rotate toward each other at the same time, so that the protective gear 100 can quickly respond to the need for knee bending, and bend at an appropriate angle according to the size of the knee bending angle, thereby improving the fit between the protective gear 100 and the knee joint. Therefore, the present invention proposes a protective gear 100 that can achieve bending at multiple angles, improve the fit between the protective gear 100 and the knee joint, and then reduce the concentration of the force of the knee collision, so as to better protect the knee.

When the knee bends, the knee pushes the knee guard 300 to move, the knee guard 300 drives the gear seat 520 to move, the gear seat 520 drives the upper gear 530 and the lower gear 540 to rotate through the gear transmission mode, the upper gear 530 drives the upper fixing member 200 to rotate, and the lower gear 540 drives the lower fixing member 400 to rotate, so as to quickly respond to the need of knee bending, and perform an appropriate angle bending according to the size of the knee bending angle, thereby improving the fit between the protective gear 100 and the knee joint.
