Example one

Referring to fig. 1, in the present embodiment, a sport protector is provided, which includes an air bag 1, and a spontaneous breathing device is disposed on the air bag 1.

The spontaneous breathing apparatus includes a hollow elastic shell 20, wherein when the elastic shell 20 is not applied with an external force, the elastic shell 20 is in a swelling state, and the internal air pressure of the elastic shell is the same as the atmospheric pressure.

As shown in fig. 2, the elastic casing 20 is provided with an inhalation valve 21 and an exhalation valve 22. The air suction valve 21 is used for inflating the interior of the elastic shell 20 when the air pressure in the interior of the elastic shell 20 is less than the atmospheric pressure; the exhalation valve 22 is used to exhaust the outside of the flexible housing 20 when the air pressure inside the flexible housing 20 is greater than atmospheric pressure.

Wherein, the elastic shell 20 is arranged inside the air bag 1, and the inner cavities of the elastic shell 20 and the air bag 1 are not communicated.

The air inlet end of the inhalation valve 21 and the air outlet end of the exhalation valve 22 are both communicated with the atmosphere.

When the sport protective clothing is used, the sport protective clothing can be worn on the joint, and the joint can be bent and stretched in the sport process:

when the joint bends, the air bag 1 is extruded to a certain degree, at the moment, the elastic shell 20 in the air bag 1 is also deformed due to the increase of the air pressure in the air bag 1 and the extrusion of the joint, and the expiratory valve 22 exhausts air outwards along with the increase of the air pressure in the elastic shell 20; when the joint is stretched, the extrusion force applied to the air bag 1 is reduced, and accordingly, the elastic shell 20 in the air bag 1 rebounds under the action of the elastic force, and at the moment, the air pressure in the elastic shell 20 is lower than the atmospheric pressure, so that the air suction valve 21 inflates the elastic shell 20.

During the movement of the person, the temperature of the body surface will rise, and under the effect of the heat transfer, the temperature of the gas inside the airbag 1 and the elastic shell 20 will also rise. Under the continuous motion of joint, spontaneous expiration of autonomic respiratory device, inhale, realize the gas exchange of the inside of elasticity shell 20 and external world (atmosphere) from this to, make gasbag 1 and the inside temperature of elasticity shell 20 obtain reducing through this kind of mode to this plays radiating purpose, and improved the comfort level that the sports protective equipment dressed.

The number and position of the elastic shells 20 in the airbag 1 can be set as desired. In use, the position at which the air-bag 1 is worn can be adjusted as desired so that the elastic shell 20 can be squeezed at the joint.

The elastic case 20 may be made of an elastic material such as rubber or the like. The elastic shell 20 may be provided in a spherical or cylindrical shape, etc.

In a natural state (i.e., the elastic shell 20 is not subjected to an external force), the elastic shell 20 is in a swollen state, and the internal pressure thereof is the same as the atmospheric pressure. When pressed by an external force, the elastic shell 20 is compressed and deformed; when the external force is reduced, the elastic shell 20 rebounds under the action of the elastic force of the elastic shell; when the external force is removed by bending, the elastic case 20 is completely restored to the original state.

The principle of the elastic shell 20 can be referred to as an inflation balloon of a mercury sphygmomanometer or a foot-operated balloon inflator.

To further enhance the heat dissipation, the inhalation valve 21 and the exhalation valve 22 may be disposed on opposite sides of the airbag 1. The surface shown in fig. 1 can be considered as the outer surface of the airbag 1, wherein the inhalation valve 21 is located on the outer surface of the airbag 1 and correspondingly the exhalation valve 22 is located on the inner surface of the airbag 1.

When the sports supporter is worn, the air suction valve 21 faces outwards, and the air exhaust valve 22 faces towards the skin. When the exhalation valve 22 exhausts air, the air flow blows toward the skin and removes heat from the skin, thereby increasing the effectiveness of the heat dissipation.

The side of the exhalation valve 22 facing the skin can be provided with structures such as dimples, so that a certain distance can be kept between the exhalation valve 22 and the skin, and the exhalation valve 22 is prevented from directly pressing against the surface of the skin to influence the exhaust efficiency. Wherein, the position where the elastic shell 20 contacts with the air bag 1 can be adhered by sealing glue.

The movement of the joint provides kinetic energy, and the exchange of air with the interior of the elastic shell 20 is achieved through the inhalation valve 21 and the exhalation valve 22.

In this embodiment, the inhalation valve 21 and the exhalation valve 22 can both be gas check valves.

There are many types and kinds of gas check valves, wherein, as shown in fig. 3, a conventional gas check valve generally comprises a valve core 8 and a spring 9 for pressing the valve core 8, and the following is a simple description of the working principle of such a conventional gas check valve: when the gas pressure at the gas inlet end of the valve body is greater than the acting force of the spring 9, the gas can jack the valve core 8, and a channel in the valve body is opened, so that the gas flows out from the gas outlet end of the valve body; when the air pressure at the air inlet end is smaller than the acting force of the spring 9 or the air at the air outlet end of the valve body flows towards the inside of the valve body, the spring 9 can drive the valve core 8 to automatically reset and close the channel inside the valve body.

In summary, the gas check valve realizes one-way flow of gas by cooperation of the valve element, the spring and the like.

When the gas inlet valve is installed and used, the gas inlet or the gas outlet can be controlled by adjusting the positions of the gas inlet end and the gas outlet end of the gas one-way valve.

The opening pressure of the gas one-way valve can be adjusted by setting parameters such as the shape of a valve core of the suction valve 21, the elastic modulus of a spring and the like, so that when the air pressure in the elastic shell 20 is smaller than the atmospheric pressure, the suction valve 21 can inflate the elastic shell 20; by setting parameters such as the shape of the valve core of the exhalation valve 22 and the elastic modulus of the spring, the exhalation valve 22 exhausts air to the outside when the air pressure inside the elastic shell 20 is greater than the atmospheric pressure.

In the present embodiment, an autonomous inflator for inflating the interior of the airbag 1 may be further provided to the airbag 1. The air pressure inside the airbag 1 can be kept in a stable interval by the autonomous inflating device.

The autonomous inflation device may include an elastic bag 30, and the elastic bag 30 is provided with an intake valve 31 for inflating the inside of the elastic bag 30 and an exhaust valve for exhausting gas inside the elastic bag 30. Wherein, the air inlet end of the air inlet valve 31 is communicated with the atmosphere, and the air outlet end of the air outlet valve is communicated with the inside of the air bag 1.

The structure and principle of the autonomous inflation device are the same as those of the autonomous breathing device, the elastic bag 30 corresponds to the elastic shell 20, the air inlet valve 31 corresponds to the inhalation valve 21, and the air outlet valve corresponds to the exhalation valve 22.

The elastic bag 30 may be disposed at the middle of the airbag 1 or at a position where the airbag 1 is most deformed after being worn. This ensures that the elastomeric bladder 30 can be deformed significantly and thus inflated better. The automatic inflating device completes the inflating action through the kinetic energy provided by the movement of the joint.

In order to prevent the air pressure inside the air bag 1 from being too large, the air bag 1 is provided with an exhaust valve for exhausting air outwards when the air pressure inside the air bag is larger than the preset air pressure. The air outlet valve can also use an air one-way valve, and the preset air pressure is not more than the maximum air pressure which can be borne by the air bag 1.

In this embodiment, the airbag 1 may be made of a material having elasticity. In order to improve the durability of the airbag 1 and protect the airbag 1, the surface of the airbag 1 may be provided with a protective layer, wherein the protective layer may use a nano-coating or the like.

Since it is detachable, the user can change the number of the air bags 1 according to the portion to be used. It should be noted that after the number of the air bags 1 is adjusted, the corresponding positions on the air bags 1 need to be sealed or communicated.

Before the sport protective clothing is used, the air bag 1 needs to be inflated through devices such as an inflator and the like, so that the air bag 1 inflates. Wherein, in order to conveniently inflate the gasbag 1, the gasbag 1 can be provided with an inflation hole 4 for inflating the inside of the gasbag 1. After the inflation is completed through the inflation hole 4, it needs to be sealed to prevent air leakage.

Because the air bag 1 is filled with gas, the air bag 1 can provide corresponding protection and buffering for the joint.

The sport protector can be worn on other non-joint parts of the body besides protecting the joints. By setting the shape and size of the airbag 1, the sport supporter can be made into knee pads, wrist pads, elbow pads, ear pads, head pads, crotch pads, hip pads, and the like.

To facilitate wearing the air-bag 1 on the body, the sport protector may also comprise a base pad 5 for mounting the air-bag 1.

In order to fix the position of the air bag 1 conveniently, the bottom cushion 5 can be provided with a groove structure and the like corresponding to the shape of the air bag 1. When the air bag is installed, the air bag 1 can be placed in the groove.

Since the bottom pad 5 is directly contacted with the skin during wearing, the bottom pad 5 can be made of skin-friendly and breathable material.

In this embodiment, the bottom cushion 5 and the airbag 1 can be detachably connected.

Specifically, the bottom pad 5 and the airbag 1 may be connected by a hook and loop fastener or a double-sided tape.

Because the bottom pad 5 is detachably connected with the air bag 1, the bottom pad 5 can be cleaned after the air bag 1 is detached from the bottom pad 5, so that the cleanness of the bottom pad 5 is ensured.

The sport protective clothing is convenient to store and carry. When the sports protective equipment does not need to be used, the air bag 1 and the base pad 5 can be separated, the base pad 5 is folded or bent simultaneously through exhausting air in the air bag 1, so that the occupied space is reduced, and the sports protective equipment and the base pad can be conveniently placed in a drawer, a backpack, a luggage case and the like.

In order to fix the sport tool on the corresponding part of the body, the bottom mat 5 may be provided with a binding piece for binding the bottom mat 5 on the body.

In this embodiment, the binding may be selected from a string or/and a velcro.

Referring to fig. 1, when the magic tape is used as the binding piece, the left side of the base pad 5 may be provided with round hairs 6 of the magic tape, and correspondingly, the right side of the base pad 5 may be provided with barbed hairs 7 of the magic tape.

When the bottom pad 5 is bound at the joint position, along with the motion of joint, the bottom pad 5 can produce certain deformation, and simultaneously, there may be the difference in different users' size, for the comfort level of improving wearing and the size that adapts to different users, the bottom pad 5 can adopt elastic fabric to make.
