[0023] like Figure 1-Figure 3 As shown, the utility model proposes an inflatable telescopic cover

[0024] In an exemplary embodiment, the inflatable telescopic hood includes a base 1 and a top cover 2, a plurality of airbag units 5 are stacked between the base 1 and the top cover 2, the airbag unit 5 includes an air storage space 7, a diaphragm 6 is provided between adjacent airbag units 5, and the air storage spaces 7 of adjacent airbag units 5 are connected through the diaphragm 6.

[0025] In this embodiment, the inner membrane 501 and the outer membrane 502 are arranged and connected in sequence through the diaphragm 6. The special setting method of the outer membrane 502 is adopted, so that the overall size of the telescopic cover when not inflated is smaller than the size after inflating, reducing the volume of the entire telescopic cover and effectively saving the space for storing the telescopic cover.

[0026] In an exemplary embodiment, the diaphragm 6 includes a first connecting portion 601 and a second connecting portion 602 . A vent hole 603 is provided on the diaphragm 6 , and the vent hole 603 is disposed between the first connecting portion 601 and the second connecting portion 602 .

[0027] In this embodiment, the first connecting portion 601 and the second connecting portion 602 on the diaphragm 6 can be used to connect the inner membrane 501 and the outer membrane 502 respectively, and through the provided vent holes 603, gas can enter the air storage space 7 inside each airbag unit 5 through the vent holes 603, causing the airbag unit 5 to expand and ultimately protect the device.

[0028] For example, Figure 2 and Figure 3 As shown, the airbag unit 5 includes an inner membrane 501 and an outer membrane 502. The two ends of the inner membrane 501 are respectively arranged on the first connecting portion 601 of the adjacent diaphragm 6, and the two ends of the outer membrane 502 are respectively connected to the second connecting portion 602 of the adjacent diaphragm 6. The inner membrane 501 includes a first fixing portion 5011 and a second fixing portion 5012 for connecting to the first connecting portion 601. A protrusion 5013 is provided between the first fixing portion 5011 and the second fixing portion, and the protrusion 5013 is arranged toward the outer membrane 502. The outer membrane 502 includes a third fixing portion 5021 and a fourth fixing portion 5022 for connecting to the second connecting portion 602. The third fixing portion 5021 and the fourth fixing portion 5022 are provided with a recessed portion 5023, which is arranged toward the inner membrane 501. The protrusions 5013 and the recessed portions 5023 are arranged alternately. When not inflated, the inner membrane 501 and outer membrane 502 are arranged in a "V" shape, with the tip of the inner membrane 501 facing right and the tip of the outer membrane 502 facing left, and the tip of the outer membrane 502 positioned above the tip of the inner membrane 501, staggered. Therefore, when not inflated, the outer membrane 502 is concave inward, and the overall diameter of the telescopic cover is smaller than the diameter when inflated. When inflated, the air in the air storage space 7 drives the inner membrane 501 and outer membrane 502 to expand, ultimately forming an elliptical shape.

[0029] It is worth noting that since the outer membrane 502 needs to expand outward when the airbag is inflated and expanded, and the outer membrane 502 needs to be stretched in order to expand, the size of the outer membrane 502 needs to be wider than the inner membrane 501. The ratio of the inner membrane 501 to the outer membrane 502 depends on the elasticity of the membrane material used. It is sufficient when the expanded height of the outer membrane 502 is close to the expanded height of the inner membrane 501.

[0030] For example, in this embodiment, when the material of the airbag unit 5 is selected as TPU or PVC, it can be formed through integral welding at extremely low cost, which is lower in cost and simpler in operation.

[0031] It should also be noted that in this embodiment, the connection between the outer membrane 502 and the inner membrane 501 can be mechanically fixed by welding or bonding. When the edge of the inner membrane 501 and the edge of the outer membrane 502 are connected to the diaphragm 6 by welding, the welding effect is best when the two are made of the same material.

[0032] It should also be noted that during the welding process, the airbag unit 5 and the diaphragm 6 can be separated by a PET film at the welding point where welding is not required, and then welded by pressing up and down, and finally the PET film and excess edges are removed to complete the welding. This method is limited to welding materials through electromagnetic waves and ultrasonic waves, and the remaining materials can be welded by other methods such as gluing.

[0033] It should also be noted that the bottom and top airbag units 5 need to be connected to the base 1 and the top cover 2, which can be fixed by gluing, or by welding if the two are made of the same material.

[0034] In an exemplary embodiment, a plurality of evenly distributed air inlets and outlets 3 are provided on the base 1, the output ends of the air inlets and outlets 3 are connected to the air storage space 7, and the input ends of the air inlets and outlets 3 are used for connecting to an external air source, and the air source enters the air storage space 7 of each airbag unit 5 through the air inlets and outlets 3 and the air vents 603.

[0035] In this embodiment, the air inlet and outlet 3 are provided so that the pressurized gas in the air source can enter the airbag unit 5 from multiple locations, thereby improving the inflation efficiency.

[0036] For example, the number of the air inlets and outlets 3 in this embodiment can be adaptively set according to the base 1 . In this embodiment, the number of the air inlets and outlets 3 is 30.

[0037] In an exemplary embodiment, the base 1 is provided with a placement channel 8 for placing devices along the extension direction of the top cover 2 . When the telescopic cover is inflated, the airbag unit 5 expands and fixes the devices in the placement channel 8 .

[0038] In this embodiment, the device to be protected is placed in the placement channel 8, and after inflation, the airbag unit 5 expands rapidly to protect the device.

[0039] It is worth noting that in this embodiment, the main usage scenario of the telescopic cover is the protection of key electronic components in space. For this reason, the membrane material of the telescopic cover is also very important. Materials that can shield electromagnetic wave interference are selected. For components such as lenses that are sensitive to optical fibers, a certain degree of light shielding is also required. After inflation, the telescopic cover is unfolded into two layers, which can better block electromagnetic wave interference. As for the light-shielding property of the telescopic cover, it can block light interference well on the side. For the light from the top, the structural design cleverly extends inward through the diaphragm 6 to form a light shielding plate to reduce the interference of light on the middle lens.

[0040] In an exemplary embodiment, a plurality of evenly distributed support rods 4 are provided on the base 1 , and the entire telescopic cover can be supported by the provided support rods 4 .

[0041] In summary, the utility model arranges the inner membrane 501 and the outer membrane 502 so that the inner membrane 501 and the outer membrane 502 are arranged and connected in sequence through the diaphragm 6, and adopts a special arrangement method for the outer membrane 502, so that the radial dimension of the telescopic cover as a whole when not inflated is smaller than the dimension after inflating, thereby reducing the volume of the entire telescopic cover and effectively saving the space for storing the telescopic cover.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
