Detailed Description

The present invention will be described in further detail with reference to embodiments shown in the drawings.

Referring to fig. 1 to 6, the shoe for protecting a knee of the present embodiment includes: the sole comprises a sole 1 and a vamp 2, wherein the vamp 2 is arranged on the sole 1, a buffer device 3 is arranged on the sole 1, the buffer device 3 comprises a heel lifting component 31, a half sole lifting component 32 and a connecting component 33, the connecting component 33 is connected with the heel lifting component 31 and the half sole lifting component 32, and the heel lifting component 31 and the half sole lifting component 32 are linked.

Through the technical scheme, the heels land first during normal walking, then the heels are lifted first, then the half sole is lifted, in the process of flat ground walking, the left foot and the right foot step back and forth on the ground, when stepping on the ground, the heel lifting assembly 31 descends, the linkage assembly drives the half sole lifting assembly 32 to ascend, the half sole lifting assembly 32 ascends, the heel lifting assembly 31 descends, so that the sole and the sole 1 incline, the half sole is high, the heel is low, the included angle theta between the shank and the vertical surface is smaller, the included angle phi between the thigh and the shank is larger, N1 and N2 are further reduced, the stress of the knee joint is small, the wear of the knee joint is reduced, and the probability of the damage of the knee joint; when climbing stairs, the stairs are repeatedly moved every time, the bearing shank keeps the same inclination angle theta 1 when just contacting with the step and is fixed with the included angle of the thigh, in the moving process, namely in the exchange process of the bearing leg, the shank and the thigh are stretched into a straight line at a constant speed, the included angle theta 1 between the shank and the vertical plane is reduced to 0 in the stretching process, at the moment, the non-bearing leg is changed into the bearing leg and is contacted with the step in the same shape, when the bearing leg is contacted with the step, the half sole is high, the heel is low, and the theta 1 is smaller than the theta 1 when going upstairs by wearing traditional damping shoes and air cushion shoes, so that N1 and N2 are reduced, F2 is reduced, the stress of the knee joint is small, the wear of the knee joint is reduced, and the probability; when climbing stairs downwards, similar to the initial state when climbing stairs, the big leg and the small leg of the bearing leg form a certain angle to be abutted against the step surface, the big leg and the small leg of the non-bearing leg are stretched into a straight line to be abutted against the step surface, in the motion process, the bearing leg keeps the big leg and the small leg stretched into a straight line initially, in the motion process, namely the exchange process of the bearing leg, the thigh and the small leg completely form a certain angle at a constant speed, the included angle delta between the small leg and the vertical surface in the stretching process can be increased from 0, at the moment, the non-bearing leg is changed into the bearing leg, the half sole is high and the heel is low, the delta angle is smaller than the delta angle when the traditional damping shoe and the air cushion shoe are worn to climb the stairs, N1 and N2 are reduced, F. When the sole is lifted, the sole presses the sole lifting component 32, and then the connecting component 33 is driven to drive the heel lifting component 31 to reset. The existing shoes have the defects that the heel can not descend or only the heel can descend partially when walking, the former does not have the effect of protecting the knee joint, the latter has poor single use effect, particularly, in the process of walking stairs, the stress of the knee joint is 7-8 times of the weight of a human body, the pressure born by the knee joint is large, and the knee joint is easy to damage. The knee joint is protected effectively by lifting the half sole and lowering the heel to change the inclination angle of the shank during walking and change the walking posture.
