DETAILED DESCRIPTION

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-6 The protective pad for sports training shown in the figure includes an upper pad 1, an inflatable pad 2 and a lower pad 3, wherein the inflatable pad 2 is fixed between the upper pad 1 and the lower pad 3; an elastic drawstring 4 is connected between the edge of the upper pad 1 and the edge of the lower pad 3, and the elastic drawstring 4 confines the inflatable pad 2 between the upper pad 1 and the lower pad 3.

[0027] like Figure 1-3 As shown, the upper pad 1 and the lower pad 3 are both rectangular plates made of foam material, and the outer parts of the upper pad 1 and the lower pad 3 are detachably covered with dust covers. The dust covers are made of waterproof fabric, and a circle of buckles (not shown) are sewn around the dust covers located on the sides of the upper pad 1 and the lower pad 3. The elastic pull bands 4 are interlaced between the buckles of the upper pad 1 and the buckles of the lower pad 3, so that the inflatable cushion 2 is confined between the upper pad 1 and the lower pad 3.

[0028] like Figure 3-5 As shown, the inflatable cushion 2 is made of PVC, polyurethane or silicone, and includes an upper cushion 21 and a lower cushion 22. The upper cushion 21 includes an upper substrate 211 of a rectangular structure, the size of the upper substrate 211 is the same as that of the upper protective pad 1, a plurality of upper air bags 212 are arranged at intervals on the lower surface of the upper substrate 211, an upper air channel 213 is connected between the plurality of upper air bags 212, an upper inflation tube 214 is installed on one of the upper air bags 212 at the edge, and a valve is installed on the upper inflation tube 214. The upper air bag 212 can be inflated through the upper inflation tube 214.

[0029] like Figure 5 As shown, the lower air cushion 22 includes a lower substrate 221, and the size of the lower substrate 221 is the same as that of the upper substrate 211. A plurality of lower air bags 222 are arranged at intervals on the upper surface of the lower substrate 221, and a lower air channel 223 is connected between the plurality of lower air bags 222. A lower air bag 222 located at the edge is installed with a lower inflation tube 224, and a valve is installed on the lower inflation tube 224, and air can be inflated into the lower air bag 222 through the lower inflation tube 224. The lower air bags 222 and the upper air bags 212 are arranged alternately, so that the upper air bags 212 and the lower air bags 222 fill the entire plane of the protective cushion.

[0030] When in use, air is inflated into the upper air cushion 21 and the lower air cushion 22 through the upper air pipe 214 and the lower air pipe 224, and the valves on the upper air pipe 214 and the lower air pipe 224 are closed to keep the air cushion 2 in an inflated state. After use, the valves on the upper air pipe 214 and the lower air pipe 224 are opened to discharge the air in the air cushion 2, thereby reducing the volume of the protective cushion and facilitating storage and transportation.

[0031] By configuring the inflatable cushion to have multiple airbag structures, the requirements for materials and processes of the inflatable cushion can be reduced, thus saving production costs; the interlaced airbags can not only improve the uniformity of the elasticity of the surface of the inflatable cushion, but also prevent the inflatable cushion from slipping, thereby ensuring the stability of the inflatable cushion.

[0032] As a preferred embodiment of the present application, the inflatable cushion 2 can be designed to be multi-layered. By selectively inflating different numbers of inflatable cushions 2, the thickness of the protective cushion can be adjusted to facilitate different application scenarios.

[0033] As a preferred embodiment of the present application, the height of the upper airbag 212 located at the edge is greater than the height of the upper airbag 212 located in the middle; or the height of the lower airbag 222 located at the edge is greater than the height of the lower airbag 222 located in the middle. This makes the thickness of the edge of the protective pad greater than the thickness in the middle. When an athlete falls on the protective pad, the protective pad is not easily rolled off due to the resistance of the edge, thereby improving the protective performance of the protective pad.

[0034] As a preferred embodiment of the present application, Figure 2 , Figure 3 , Figure 6 As shown, a flexible heating pad 5 is arranged between the inflatable cushion 2 and the lower protective cushion 3. The flexible heating pad 5 is driven by a mobile power source. The flexible heating pad 5 includes a substrate 51 of a flexible material and a heating wire 52 arranged in a U-shaped pattern on the substrate 51. A temperature sensor is enclosed in the substrate 51 to control the heating temperature. By providing the flexible heating pad 5, the inflatable cushion 2 can be heated when the temperature is low, so as to prevent the inflatable cushion 2 from hardening at low temperatures and affecting the elasticity of the inflatable cushion 2.

[0035] like Figure 3 As shown, when the inflatable pad 2 has only one layer, the flexible heating pad 5 is arranged between the inflatable pad 2 and the lower protective pad 3. Figure 2 As shown, when the inflatable pad 2 has multiple layers, the flexible heating pad 5 is arranged between the inflatable pads 2 and closer to the lower protective pad 3. Arranging the flexible heating pad 5 away from the upper protective pad 1 can reduce the impact on the flexible heating pad 5 and extend the service life of the flexible heating pad 5.

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
