DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] Example 1

[0026] See also Figure 1 A children's down jacket with cushioning protection function includes: a down jacket body 1, an annular airbag 4 is provided on the inner side of the sleeve of the down jacket body 1, and the annular airbag 4 is located in the elbow area of ​​the sleeve of the down jacket body 1 to protect the elbow of the wearer.

[0027] Please note that Figure 1 A first airbag 2 is provided on the inner side of the hat of the down jacket body 1, and a second airbag 3 is provided on the inner side of the back and the inner side of the chest of the down jacket body 1; the first airbag 2 and the second airbag 3 provide cushioning protection for the child's head, back and chest.

[0028] It should also be noted that the interiors of the annular airbag 4 , the first airbag 2 and the second airbag 3 are inflated.

[0029] See also Figure 2 , Figure 3 and Figure 4 A plurality of elastic support blocks 5 (made of rubber) are arranged inside the annular airbag 4. The plurality of elastic support blocks 5 are distributed in an annular shape inside the annular airbag 4 (such as Figure 3As shown, the elastic support blocks 5 can be 4 or more), and a flexible connector 8 is provided inside the annular airbag 4. The flexible connector 8 is annular and passes through several elastic support blocks 5 in sequence; a mounting groove is opened inside the elastic support block 5, and an insert block 10 and a slot 11 are provided inside the mounting groove. The insert block 10 and the slot 11 are opposite to each other, and the two are respectively located on both sides of the flexible connector 8.

[0030] It should be noted that when a child falls and his elbow contacts the ground, the annular airbag 4 can play a buffering and protective role, reducing the collision force on the child's elbow; when the annular airbag 4 is squeezed by the ground, the elastic support block 5 will be squeezed, causing the plug block 10 to move into the slot 11, and squeezing the flexible connector 8 into the interior of the slot 11, pulling the flexible connector 8 into the interior of the mounting groove (this mounting groove is the mounting groove of the squeezed elastic support block 5), reducing the length of the external flexible connector 8, and playing an effect of tightening the annular airbag 4, so that the sleeves of the down jacket body 1 will not move when the child falls, ensuring that the annular airbag 4 is at the child's elbow, ensuring the protective effect of the annular airbag 4, and the flexible connector 8 is pulled, which also pulls other areas of the annular airbag 4 toward the squeezed area, which is used to prevent the thickness of the squeezed area of ​​the annular airbag 4 from decreasing, ensuring that the squeezed area of ​​the annular airbag 4 can also provide a stable support for the child's elbow, ensuring the buffering and protective effect of the annular airbag 4.

[0031] In this embodiment, as a further optimized solution, please refer to Figure 3 and Figure 4 The flexible connector 8 is a hose (the hose is connected end to end), the interior of the hose is filled with gas (such as air), and a plurality of blocks 12 (made of rubber) are sleeved on the outer wall of the flexible connector 8, and there is a block 12 on both side walls of each elastic support block 5; when the plug-in block 10 squeezes the flexible connector 8, the flexible connector 8 will expand, causing it to shorten, thereby increasing the tightening amplitude of the annular airbag 4, making the annular airbag 4 more stable when fixed on the child's elbow, and further reducing the probability of it moving and exposing the child's elbow; at the same time, when the flexible connector 8 is pulled into the mounting groove, the block 12 will contact and squeeze the side wall of the elastic support block 5, preventing the elastic support block 5 from becoming flat, increasing the supporting force provided by the elastic support block 5 to the child's elbow, and increasing the buffering protection ability of the annular airbag 4.

[0032] In this embodiment, as a further optimized solution, please refer to Figure 3A plurality of support strips 9 are provided on the inner side wall of the annular airbag 4, and the plurality of support strips 9 extend along the length direction of the sleeve of the down jacket body 1. An inflation groove is provided inside the support strip 9, and the inflation groove is connected with the inner cavity of the annular airbag 4 (the support strip 9 with the inflation groove is equivalent to the airbag); when the annular airbag 4 is squeezed, part of the gas inside the annular airbag 4 enters the inflation groove of the support strip 9, so that it expands and is fully out of contact with the child's elbow, so that the annular airbag 4 is more stably fixed on the child's elbow to protect the child's elbow.

[0033] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 5 A fixed airbag 7 (the fixed airbag 7 is filled with gas) is provided on the inner side of the cuff of the down jacket main body 1. The fixed airbag 7 is annular and is connected to the annular airbag 4 through a conduit 6. When the annular airbag 4 is squeezed, part of the gas inside the annular airbag 4 enters the annular airbag 4 through the conduit 6, so that the expansion amplitude of the annular airbag 4 increases, and the annular airbag 4 fits tightly with the child's wrist, which has a fixing effect, preventing the sleeve of the down jacket main body 1 from sliding and exposing the child's arm when falling, avoiding scratches on the child's arm, and increasing the protection effect.

[0034] In this embodiment, as a further optimized solution, please refer to Figure 6 An elastic band 14 (elastic band) is provided in the cuff of the down jacket body 1, and the elastic band 14 is located on the outside of the fixed airbag 7; when the fixed airbag 7 is inflated, the elastic band 14 applies pressure to the fixed airbag 7, so that the fixed airbag 7 can fully contact with the child's wrist, ensuring that the cuff of the down jacket body 1 will not move, thereby improving the protection ability of the down jacket.

[0035] Example 2

[0036] As a further optimized solution of Example 1, please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8A winding drum 13 is provided in the cuff of the down jacket body 1, and a winding rod 15 is provided inside the winding drum 13 for rotation. A spring 16 is sleeved on the outer wall of the winding rod 15, one end of the spring 16 is connected to the winding rod 15, and the other end of the spring 16 is connected to the inner wall of the winding drum 13, one end of the elastic band 14 is connected to the winding rod 15, and the other end of the elastic band 14 is connected to the outer wall of the winding drum 13; a first through hole 17 and a second through hole 18 are respectively provided on the two side walls of the winding drum 13, the first through hole 17 is connected to the second through hole 18, the diameter of the first through hole 17 is smaller than the diameter of the second through hole 18, and the conduit 6 includes two pipes, one pipe is used to connect the first through hole 17 with the second through hole 18, and the second through hole 18 is connected to the first through hole 17. The annular airbag 4 is connected, and another pipe is used to connect the second through hole 18 with the fixed airbag 7. One end of the winding rod 15 extends into the inner cavity of the first through hole 17. A limit block 19 is slidably provided in the inner cavity of the first through hole 17. The limit block 19 cuts off the first through hole 17. A limit groove 21 is penetrated on the side wall of the winding rod 15. The limit block 19 is inserted in the limit groove 21 to limit the rotation of the winding rod 15 (at this time, the spring 16 is in a stretched state). An air flow channel 20 is provided on the limit block 19. The air flow channel 20 is T-shaped. The inlet of the air flow channel 20 is located at the end of the limit block 19 and faces the first through hole 17. The outlet of the air flow channel 20 is located on the side wall of the limit block 19.

[0037] It should be noted that when the annular airbag 4 is squeezed, part of its own gas enters the interior of the first through hole 17 through the conduit 6, and is used to push the limit block 19 out of the limit groove 21, so that a part of the limit block 19 enters the second through hole 18 (the outlet of the air flow channel 20 is located inside the second through hole 18), and the first through hole 17 is connected with the second through hole 18, so that the gas can enter the interior of the fixed airbag 7; at the same time, the restriction on the winding rod 15 is released, and under the action of the clockwork spring 16, the winding rod 15 rotates, and part of the elastic band 14 is wrapped around the outer wall of the winding rod 15, so that the elastic band 14 is tightened to apply pressure to the fixed airbag 7, so that the fixed airbag 7 is in more complete contact with the child's wrist, so that the cuff of the down jacket body 1 will not move.

[0038] It should also be noted that when the elastic band 14 is reset, the cuffs of the down jacket body 1 are pulled outward to release the elastic band 14 wrapped around the outer wall of the rolling rod 15, which will also cause the rolling rod 15 to rotate and align the limit groove with the limit block 19; a magnetic block 22 is installed inside the limit groove 21, and the limit block 19 is made of a metal material that can be attracted by magnetism; through the attraction of the magnetic block 22 to the limit block 19, the limit block 19 is inserted into the limit groove 21, and the rolling rod 15 is restricted again.
