As shown in fig. 1-3, the present utility model provides a brace comprising an outer protective cushioning impact resistant layer 100, an inner sliding patch 200, and a reset assembly.

The outer side of the inner sliding patch 200 is adapted to the inner side of the outer protective buffer impact resistant layer 100, the outer side of the inner sliding patch 200 is attached to the inner side of the outer protective buffer impact resistant layer 100, and the inner sliding patch 200 is slidably connected with the outer protective buffer impact resistant layer 100, i.e. the inner sliding patch 200 can slide along the inner side wall of the outer protective buffer impact resistant layer 100.

The reset component is disposed between the outer protective buffer impact layer 100 and the inner sliding patch 200, two ends of the reset component are respectively connected with the outer protective buffer impact layer 100 and the inner sliding patch 200, and in a natural state, the reset component has a trend of enabling the outer side of the inner sliding patch 200 to be attached to the inner side of the outer protective buffer impact layer 100, namely when the inner sliding patch 200 and the outer protective buffer impact layer 100 are subjected to opposite external force, the inner sliding patch 200 and the outer protective buffer impact layer 100 need to overcome the elastic force of the reset component to relatively slide, and after the external force disappears, under the action of the reset component, the inner sliding patch 200 and the outer protective buffer impact layer 100 are enabled to be close to each other until the outer side of the inner sliding patch 200 is attached to the inner side of the outer protective buffer impact layer 100, so as to restore to the original position.

When the outer protective buffer impact layer 100 is in collision with the ground, the outer protective buffer impact layer 100 is in contact with the ground, the outer protective buffer impact layer 100 keeps not or slowly slides forward under the action of friction force between the outer protective buffer impact layer 100 and the ground, and the inner sliding patch 200 continues to slide forward under the action force between the inner sliding patch 200 and the human body, so that the inner sliding patch 200 and the outer protective buffer impact layer 100 relatively slide against the elastic force of the reset assembly.

From the momentum theorem ft=mv ₁-MV₂, it follows that:

In the process of collision between the human body and the ground, under the condition that the initial speed V ₁ and the final speed V ₂ (usually zero) are fixed, the longer the time is used in the process of reducing the human body from the initial speed V ₁ to the final speed V ₂, the smaller the impact force F generated in the process of collision is, and conversely, the larger the impact force F generated is.

In the conventional protective tool, in the collision process of a human body and the ground, although the protective tool prevents the human body from directly colliding with the ground, the speed is instantaneously reduced from the initial speed V ₁ to the final speed V ₂, so that the impact force generated by the conventional protective tool is large, and the protective effect is poor.

In the protective clothing provided by the utility model, in the collision process of the human body and the ground, the inner sliding patch 200 and the outer protective buffer impact layer 100 can relatively slide, and in the process of relatively sliding the inner sliding patch 200 and the outer protective buffer impact layer 100, the elasticity of the reset component needs to be overcome. Therefore, the time required for the initial speed V ₁ to be reduced to the final speed V ₂ is longer, so that the generated impact force is smaller, and the protection effect is greatly improved.

In one embodiment, the reset assembly comprises an elastic member 300, the elastic member 300 is provided with m, wherein m is greater than or equal to 2, a first end of the elastic member 300 is fixedly connected with the inner sliding patch 200, and a second end of the elastic member 300 is fixedly connected with the outer protective buffer impact resistant layer 100. The reset component with the structure has the advantages of simple structure, reasonable design and convenient manufacture.

Specifically, as shown in fig. 3, when the protector is small (e.g., wrist protector), m=2, and two elastic members are symmetrically disposed at both ends of the protector.

As shown in fig. 1, when the brace is large (e.g., knee pad, elbow pad, hip pad, etc.), since a plane can be defined by three points, preferably, m is equal to or greater than 3, so as to achieve the purpose of improving the resetting effect and the buffering effect, in this embodiment, m=4. With the increase of the protective gear, in order to achieve better protection effect, the number m of the elastic pieces is also increased.

Preferably, the polygon surrounded by the m elastic pieces 300 is an axisymmetric pattern, and one symmetry axis of the polygon coincides with the symmetry axis of the inner sliding patch 200 and/or the outer protective buffer impact layer 100, so that in a natural state, the forces applied by the elastic pieces 300 to the two sides of the inner sliding patch 200 or the outer protective buffer impact layer 100 are kept consistent, thereby achieving the purpose of improving the resetting effect and the buffering effect.

Preferably, any two adjacent elastic members 300 are arranged in a splayed shape, so that the elastic force of any two adjacent elastic members 300 on the inner sliding patch 200 or the outer protective buffer impact resistant layer 100 is directed to the center of the inner sliding patch 200 or the outer protective buffer impact resistant layer 100, thereby achieving the purpose of further improving the resetting effect and the buffering effect.

Preferably, the elastic member 300 is made of rubber and/or silicone. The elastic member 300 of this structure has a simple structure and is convenient to manufacture.

Preferably, the connecting pieces 400 are further included in one-to-one correspondence with the elastic pieces 300, the connecting pieces 400 are fixedly embedded in the outer protection buffer impact-resistant layer 100, and the second ends of the elastic pieces 300 are detachably connected with the connecting pieces 400.

Because the outer protective cushioning impact-resistant layer 100 is thicker, not only is it convenient to connect the elastic member 300 with the outer protective cushioning impact-resistant layer 100, but also it is convenient to replace the elastic member 300 when the elastic member 300 is damaged, by embedding the connecting member 400 in the outer protective cushioning impact-resistant layer 100.

Preferably, the second end of the elastic member 300 has a first connecting through hole 310, and the connecting member 400 is clamped with the second end of the elastic member 300 through the first connecting through hole 310, so as to achieve the purpose of facilitating installation and replacement of the elastic member 300. Specifically, the connecting piece 400 is provided with a first connecting portion, and one end of the first connecting portion, which is far away from the connecting piece 400, is provided with a first limiting portion 410. When in use, the first connecting portion passes through the first connecting through hole 310, and under the action of the first limiting portion 410, the purpose of preventing the connecting piece 400 from being separated from the elastic piece 300 is achieved, and the purpose of connecting the elastic piece 300 with the connecting piece 400 is achieved.

Preferably, the inner sliding patch 200 is provided with second connecting through holes 210 corresponding to the elastic members 300 one by one, and the first ends of the elastic members 300 are clamped with the inner sliding patch 200 through the second connecting through holes 210, so as to achieve the purpose of facilitating installation and replacement of the elastic members 300. Specifically, the first end of the elastic member 300 is provided with a second connection portion, and the end of the second connection portion, which is far away from the connection member 400, is provided with a second limiting portion 320. When in use, the second connecting portion passes through the second connecting through hole 210, and under the action of the second limiting portion 320, the purpose of preventing the elastic member 300 from being separated from the inner sliding patch 200 is achieved, and the purpose of connecting the elastic member 300 and the inner sliding patch 200 is further achieved.

Preferably, the inside of the outer protective buffer impact resistant layer 100 is provided with a space avoiding groove 110 for installing the elastic member 300, and the connection member 400 is embedded at one end of the space avoiding groove 110.
