Knee-pad usually has the function of braking, heat preservation, health care etc., wherein the braking action of knee-pad is to be closed by knee-pad to knee
Section applies certain pressure and kneecap is fixed on metastable position, to play the role of protecting kneecap.
When knee flexion angles are smaller, kneecap stock supports belt sag, quadriceps muscle of thigh control unstable, simultaneously because outside knee
It turns over, the loxosis of turn up position and the quadriceps muscle of thigh of kneecap tendon makes kneecap have the tendency that slipping outward.Knee flexion angles from 0 degree to
10 degree of ranges are the kneecap most unstable stages.
Currently, no matter aperture knee-pad or elastic knee cap, when knee flexion angles are larger, knee-pad is significantly drawn
It stretches, the pulling force of knee-pad significantly increases, while kneecap significantly protrudes from knee joint, and the pulling force high concentration of knee-pad is in kneecap
And its surrounding, knee-pad is very strong to the crystallized ability of kneecap at this time.But when knee joint is not bent and bending angle is smaller, by
Smaller in the degree of kneecap protrusion, knee-pad is all smaller to kneecap and surrounding pressure, and therefore, traditional knee-pad is not curved in knee joint
Bent and bending angle is obviously insufficient to the crystallized ability of kneecap when smaller.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple structure and reasonable design, make
With the knee-pad of convenient protection kneecap.
To achieve the above object, the technical solution adopted by the present invention is that: it include knee pad body and kneecap protective device；Institute
The kneecap and its kneecap peripheral part for the knee pad body stated use sandwich；Kneecap protective device is located at the interlayer of knee pad body
In structure；Sandwich includes internal layer and outer layer；The internal layer of sandwich is equipped with the annular soft pad of package kneecap；Kneecap protection
Device includes elastic device and the protection ring being located at the top of elastic device；The bottom of elastic device is fixedly connected with annular soft pad；
Further, when kneecap protective device is located on knee-pad, elastic device is compressed 20%-the 80% of total deformation in advance；
Further, the elastic device is using flush end to top wave spring.
After adopting the above structure, a kind of knee-pad for protecting kneecap of the present invention, has the advantage that
1, when with helical spring dynamics having the same and deflection, flush end can subtract the height of top wave spring than helical spring
Few 50%, the volume and weight of kneecap protective device can be reduced, the wear comfort of knee-pad is improved；
2, when wearing knee-pad, since kneecap protective device protrudes from kneecap outer surface, the shield of the internal layer for the knee-pad being bonded with kneecap
The outer layer stretcher strain of knee pulling force very little, knee-pad is maximum, and therefore, the pulling force of knee-pad concentrates on the outer layer of knee-pad and protects to kneecap
Device applies very big radial pressure；It is not bent in knee joint and when bending angle very little, wave spring can be to kneecap and its periphery
Region applies biggish radial pressure, generates good fixed function；
3, when knee flexion angles increase, wave spring further compresses, and the present invention increases with it the pressure of kneecap, fixed to make
With further strengthening；
4, since the present invention protrudes from kneecap and top has protection ring, when head-on crash occurs for knee and other objects
When, wave spring forced contraction simultaneously collectively forms the sky that can accommodate kneecap completely with the annular soft pad of the protection ring at top and bottom
Chamber can play the role of kneecap buffering and blocking, kneecap is avoided to be injured by shock.
