Description

Shear thickening liquid motion ankle guard

Technical Field

The invention relates to the technical field of sports goods, in particular to a shear thickening liquid sports ankle brace.

Background

In sports competition, injuries can not be avoided, wherein ankle sprain is particularly common, athletes exert too hard force during running and jumping, fall feet and have improper posture, ankle joints instantaneously move out of range under the action of excessive external force and inertia, joint heads and joint sockets are dislocated instantaneously, muscles, ligaments and joint capsules are excessively stretched or twisted, and tearing and internal bleeding are generated, so that ankle joint sprain is caused. The ankle is an important sports organ, the health of the ankle brace is closely related to the sports performance and the career of athletes, and the ankle brace is beneficial to protecting the ankle and recovering the health more quickly by wearing an advanced pair of sports ankle braces.

Sports ankle braces sold in the market at present are roughly classified into two types: rigid ankle braces and flexible ankle braces. Rigid ankle braces typically use a rigid solid splint to provide support to the ankle, and flexible ankle braces typically use a highly elastic fabric to support the ankle.

The ankle guard of current adoption rigid design can play fine fixed and guard action when ankle portion receives violent impact, but can make the person of wearing ankle produce uncomfortable sense under the condition of wearing time for a long time, and the person of wearing is but can't carry out slight enstrophe or the valgus of ankle department and stretch out because of the strong holding power of rigidity ankle guard to ankle joint and is extended, and uncomfortable sense can't be alleviated. Therefore, when a wearer wears the rigid ankle protector, the wearer often feels discomfort caused by the fact that the ankle is not stretched and stretched well;

the ankle guard adopting the flexible design is softer and lighter than a rigid ankle guard, a wearer can move the ankle at any time to eliminate discomfort, but the ankle guard cannot provide enough supporting force for fixing protection when the ankle is subjected to severe impact and the ankle of the wearer is about to be sprained due to the fact that the supporting force provided by the high-elasticity fabric to the ankle is limited, and the ankle of the wearer is easy to be sprained. Thus, while comfort is assured, flexible ankle braces do not provide adequate protection.

Shear Thickening Fluid (STF) is a heterogeneous particle suspension formed by dispersing nano or micron particles into newtonian Fluid, belongs to a novel intelligent material, and has excellent buffer characteristics. Under normal state or with slow shearing rate, the shear stress is small, and the soft liquid property is achieved; when strong impact, shearing or extrusion force is applied to the outside to cause the shear thickening liquid surface and the internal shear rate to be extremely high, the apparent viscosity of the shear thickening liquid is greatly increased, and the liquid becomes very hard and shows the mechanical property similar to that of a solid.

Patent CN109944074A proposes a fabric for preventing a joint sprain, which has both strength and flexibility, but cannot closely adhere to a human body, and is not a sports protector, and therefore, it has only a function of blocking an impact of an external force and a splinter, and cannot play a sports protection function for preventing a joint sprain, because it is a sport protector. The invention provides the design of the compression sleeve, the elastic bandage and the winding belt, so that the shear thickening liquid can be partially clung to the joint to play a role in preventing the joint from being sprained.

As the commercially available rigid sport ankle protector is protected by rigid solid materials, a wearer cannot turn left and right to twist the ankle to stretch after wearing the ankle, and discomfort can be caused after the wearer wears the ankle protector for a long time; in the sport ankle protector, when a wearer feels that the ankle is untimely in a normal state, the wearer can slowly move the ankle to stretch, at the moment, the shear rate of the ankle joint on the shear thickening liquid 104 in the plastic layer 102 is low, the shear thickening liquid 104 is very soft, the movement of the ankle joint cannot be hindered, and the comfort of wearing the ankle protector is guaranteed.

When danger occurs, the commercial flexible sports ankle protector can absorb the impact force of partial ankle sprain, but the ankle sprain cannot be effectively prevented because the flexible sports ankle protector adopts flexible materials for protection; when the sports ankle protector disclosed by the invention is in danger, the joint head and the glenoid fossa in the ankle joint of a wearer start to generate instantaneous dislocation with extremely high speed, and the surface and the inside of the shear thickening liquid 104 in the closed hollow thin tube are subjected to huge impact force generated by high-speed dislocation of the joint, so that the shear thickening liquid 104 is extremely high in shear speed, further dislocation of the joint head and the glenoid fossa is prevented, and the effects of fixing the ankle and preventing sprain are achieved.

The working principle is as follows: as the commercially available rigid sport ankle protector is protected by rigid solid materials, a wearer cannot turn left and right to twist the ankle to stretch after wearing the ankle, and discomfort can be caused after the wearer wears the ankle protector for a long time; in the sport ankle protector, when a wearer feels that the ankle is untimely in a normal state, the wearer can slowly move the ankle to stretch, at the moment, the shear rate of the ankle joint on the shear thickening liquid 104 in the plastic layer 102 is low, the shear thickening liquid 104 is very soft, the movement of the ankle joint cannot be hindered, and the comfort of wearing the ankle protector is guaranteed.

When warming up, the ankle part drives the fixing ring 701 to move, the fixing ring 701 drives the first limiting block 702 to move through the first rotating shaft 704, the first limiting block 702 drives the second connecting rod 712 to move, the second connecting rod 712 pushes the third fixing block 710 through the fourth rotating shaft 711, the fixing ring 701 extrudes the closed hollow tubule 103, when the shear thickening liquid 104 in the closed hollow tubule 103 is hardened by pressure, the fixing ring 701 pushes the second fixing block 703 to move, the first rotating shaft 704 drives the first connecting rod 706 to move through the second rotating shaft 705, the first connecting rod 706 drives the sliding block 708 to move through the third rotating shaft 709, so that the sliding block 708 moves in the sliding groove 707, when a sportsman is warming up, when the shear thickening liquid 104 receives a large force, the hardened sportsman's wrist part can still move slightly downwards.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
