Shock-absorbing protective gear for lower limbs

Abstract

The invention provides a buffer and shock-absorbing protective tool for a lower limb. The buffer and shock-absorbing protective tool comprises an upper side shank protective support, upper side bandages, a liner, spring shock absorbers, a lower side shank protective support, a lower side bandage and a shock-absorbing shoe, wherein the upper side shank protective support is U-shaped, and the upper side bandages are fixedly riveted at the two ends of the upper side shank protective support; the lower side shank protective support is U-shaped, and the lower side bandage is fixedly riveted at the two ends of the lower side shank protective support; the two sides of the upper side shank protective support and upper spring seats on the spring shock absorbers are in fastening connection through first connecting pieces; the two sides of the lower side shank protective support and one ends of the spring shock absorbers are in fastening connection through second connecting pieces; the upper end of a third connecting piece and the lower side shank protective support are in fastening connection while the lower end of the third connecting piece is connected with the shock-absorbing shoe through a flexible hinge; and the liner is detachably mounted on the inner sides of the upper side shank protective support and the lower side shank protective support. The buffer and shock-absorbing protective tool can perform buffer and shock absorption in two times, and is adjustable in the shock-absorbing effect, comfortable to wear, light in weight and convenient, and high in economic value.

Description

technical field [0001] The invention relates to the field of exoskeleton protectors for lower limbs, in particular to cushioning and shock-absorbing protectors for lower limbs. Background technique [0002] The knee joint is the largest and most complex joint in the human body. It bears a lot of weight and has a large amount of exercise. It is the hub of lower limb activities, so its incidence rate ranks first among all joints. The ankle is also a key part of human beings to maintain various execution actions, and it is also more sensitive. Areas prone to sprains. In the process of walking, when the feet swing and hit the ground, the instantaneous impact force from the ground will cause the whole body to vibrate to a certain extent from bottom to top, and as the speed increases, the impact and vibration will become more severe. Vigorous, especially when descending steps or exercising vigorously, the impact force and vibration of the ground on the knee joint and ankle joint ...

AI Technical Summary

Problems solved by technology

[0003] The cushioning and shock absorbing devices currently on the market are only for the foot or ankle joints. For example, the Chinese patent authorization number CN204501524U, the authorization date is July 29, 2015. The name of the utility model patent is a three-degree-of-freedom flexible exoskeleton. The ankle joint device achieves the effect of cushioning and shock absorption through the design of the shockproof filling layer of the plantar support, the elastic support, the flexible rotation pair of the foot side support, and the rear damper. The disadvantage is that the shock absorption mechanism The shock-absorbing effect is average, and it can only buffer the impact force and vibration at the sole of the foot or the ankle joint once, but the impact force and vibration that have been transmitted cannot be attenuated twice, and it will also cause knee joint damage and wear; secondly, the whole set of devices The cushioning and shock absorption capacity cannot be adjusted, and cannot adapt to the specific requirements of each user
