[0002] Protective gear is a kind of protective equipment often worn by athletes, including those usually worn to protect the joints, lumbar spine or other soft parts of the human body, such as elbow pads, knee pads, hip pads or waist pads, etc.

[0003] Usually, the structure of the protective gear includes an inner liner and a cover wrapped around the outer layer of the inner liner, wherein the component that plays a protective and cushioning function is the inner liner. In the prior art, the inner liner is usually made of stacked sheets with energy-absorbing effects, such as polyethylene acetate sheets, high-density polyurethane foam or rubber, etc., but in the above structure, the protection effect against forces perpendicular to the sheets is usually better, because the external force from the vertical direction can maximize the deformation effect of the sheets. However, with the gradual rise of high-speed sports such as skiing or skateboarding, in the above sports, many external forces come from parallel to the sheets, such as friction with the ground, and the above structure cannot play a good cushioning role for these external forces.

If not otherwise stated, the above words have no special meaning, and therefore cannot be understood as limiting the scope of protection of the present utility model. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by technicians in the technical field of the utility model. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the utility model.

[0031] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0032] The preferred implementation of the utility model is now further described in conjunction with the accompanying drawings. Figure 1 and Figure 2As shown, the cushioning protective gear comprises an inner liner 10 and a protective cover body 20 wrapped around the outer layer of the inner liner 10, the protective cover body 20 is provided with a plurality of connecting belts 30, the connecting belts 30 are used to bind and connect with parts of the human body, such as the knees or elbows, the inner liner 10 comprises an energy absorbing layer 100, a cushioning layer 200 and a first soft layer 300 stacked in sequence from the outside to the inside, the cushioning layer 200 comprises a substrate 210, and a plurality of tiny airbags 220 are densely arranged on the side of the substrate 210 facing the energy absorbing layer 100, and under the premise of ensuring the integrity of the airbag 220, the airbag 220 is tightly fitted with the energy absorbing layer 100, and the tight fit here means that the end of the airbag 220 away from the substrate 210 is tightly fitted with the energy absorbing layer 100, and the material of the energy absorbing layer 100 comprises But it is not limited to polyvinyl acetate, high-density polyurethane foam or rubber. The material of the buffer layer 200 can be resin material, the material of the substrate 210 is hard resin material, the material of the airbag body 220 is soft resin material, and the material of the first soft layer 300 can be foam, cloth cushion, etc. The function of the energy-absorbing layer 100 and the soft layer is to play a buffering role after being deformed by the impact of external force. However, since the soft layer is closer to the human body, the material of the soft layer is a softer material. The substrate 210 and the airbag body 220 are softly connected. The soft connection here means that when the airbag body 220 is subjected to external force from the horizontal direction, since the substrate 210 and the airbag body 220 are softly connected, the airbag body 220 will deflect in the opposite direction of the external force.

[0033] In this way, when a user falls while wearing the protective gear for exercise, if the force direction is perpendicular to the energy absorbing layer 100 (direction A in the figure), after the energy absorption of the energy absorbing layer 100 is exhausted, the pressure will be transmitted to the buffer layer 200, and its airbag body 220 will be compressed in the vertical direction, thereby playing a further buffering role. When the user falls while running or skiing at high speed, due to the inertia of the movement, the force direction will be perpendicular to the energy absorbing layer 100, and there will also be a horizontal force direction (direction B in the figure). In this state, since the airbag The body 220 and the energy absorbing layer 100 are tightly fitted and the substrate 210 and the airbag body 220 are softly connected, so under the action of the airbag body 220, the energy absorbing layer 100 will be displaced relative to the buffer layer 200, thereby producing a buffering effect on the horizontal force direction. It should be noted that the distance of this displacement does not only depend on the deflection angle of the airbag body 220, because under the premise that the airbag body 220 is compressed, the deflection angle of the airbag body 220 can be further expanded, so that the displacement distance of the energy absorbing layer 100 will be further amplified, thereby further improving the buffering effect.

[0034] It can be seen from the above embodiments that compared with the prior art, the present application not only provides a buffer layer 200 in the traditional energy absorbing layer 100 and the first soft layer 300, and provides an airbag body 220 in the buffer layer 200, so that the airbag body 220 is compressed when the protective gear faces an external force perpendicular to the energy absorbing layer 100, thereby further improving the buffering effect, but also, when facing a horizontal external force, the airbag body 220 can be deflected to cause the energy absorbing layer 100 to be displaced, so that the protective gear can still have a good buffering effect when the user falls while running or skiing at high speed.

[0035] On the basis of the above embodiments, Figure 2 As shown, the protective cover body 20 includes an open portion 21 and a convergent portion 22 that gradually narrows inward along the base of the open portion 21, the energy absorbing layer 100 and the airbag body 220 are located in the open portion 21, the substrate 210 and the first soft layer 300 are located in the convergent portion 22, the convergent portion 22 tightly wraps the substrate 210 and the first soft layer 300, and the open portion 21 forms sufficient cavities 23 around the energy absorbing layer 100 and the airbag body 220, so that when facing horizontal external forces, the airbag body 220 can be deflected to cause the energy absorbing layer 100 to be displaced, so that the energy absorbing layer 100 has enough space in the protective cover body 20, thereby avoiding the phenomenon that the energy absorbing layer 100 escapes from the protective cover body 20 due to the small displacement space.

[0036] On the basis of the above embodiments, Figure 3The utility model also provides a second embodiment, which is different from the first embodiment in that a plurality of tiny airbags 220 are densely arranged on the side of the substrate 210 facing the first soft layer 300, and the airbags 220 are tightly fitted with the energy absorbing layer 100. The tight fit here means that on the premise of ensuring the integrity of the airbags 220, the end of the airbags 220 away from the substrate 210 is tightly fitted with the first soft layer 300. Compared with the first embodiment, if the force direction is perpendicular to the energy absorbing layer 100 (direction A in the figure), after the energy absorption of the energy absorbing layer 100 is exhausted, the pressure will be transmitted to the buffer layer 200, and the substrate 210 facing the airbags of the energy absorbing layer 100 and the first soft layer 300 will be in a state of being pressed against the substrate 210. The airbag body 220 will be compressed, and its buffering effect is further improved compared with the first embodiment. Secondly, there is a horizontal force direction (direction B in the figure). In this state, similar to the contact between the airbag body 220 and the energy absorbing layer 100, since the airbag body 220 and the first soft layer 300 are tightly fitted and the substrate 210 and the airbag body 220 are softly connected, under the action of the airbag body 220, the buffer layer 200 will be displaced relative to the first soft layer 300. In this embodiment, it is equivalent to that the energy absorbing layer 100 and the buffer layer 200 will be displaced at the same time. Compared with the first embodiment, the displacement distance will be further amplified, thereby further improving the buffering effect.

[0037] On the basis of the above embodiments, Figure 4 The present invention also provides a third embodiment, which is different from the first embodiment in that a second soft layer 400 is further stacked on the side of the first soft layer 300 away from the buffer layer 200, and the material of the second soft layer 400 can be foam, cloth cushion, etc. Compared with the first embodiment, the first soft layer 300 and the second soft layer 400 further improve the buffering effect.

[0038] On the basis of the above embodiments, Figure 5 and Figure 6As shown, the utility model also provides a fourth embodiment, which is different from the first embodiment in that the airbag body 220 is composed of a first airbag 221 and a second airbag 222, and the height of the first airbag 221 is greater than the height of the second airbag 222. In the fourth embodiment, the first airbag 221 and the second airbag 222 are arranged at intervals. In the first embodiment, usually, in order to ensure that the force direction is perpendicular to the energy absorbing layer 100 (direction A in the figure), the airbag body 220 can produce sufficient deformation when it is compressed in the vertical direction, and usually the airbag body 220 will be on the substrate 210 are arranged very densely, but when the airbag body 220 is subjected to an external force from the horizontal direction (direction B in the figure), the airbag body 220 will be stacked when it deflects in the opposite direction of the external force, thereby affecting the displacement distance of the energy absorbing layer 100, and further affecting the cushioning performance. In this embodiment, the height interval setting between the first airbag 221 and the second airbag 222 no longer affects the energy absorbing layer 100 perpendicular to the energy absorbing layer 100. When the airbag body 220 is compressed in the vertical direction, it can produce sufficient deformation, and it also ensures that the first airbag 221 has enough space to deflect.

[0039] On the basis of the above embodiments, Figure 7 and Figure 8 As shown, the utility model also provides a fifth embodiment, which differs from the fourth embodiment in that the first airbag 221 is arranged in the middle of the substrate 210 to form a protrusion 230, and the second airbag 222 is arranged around the protrusion 230 to form a recessed portion 240. When a user falls while running or skiing at high speed, the middle part of the protective gear usually touches the ground first. Therefore, the first airbag 221 is concentratedly arranged in the middle of the substrate 210 at a relatively high height to make the cushioning effect more obvious.

[0040] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
