Abstract

A foldable air bag, characterized by: six equilateral triangle air bags stacked together, there is a constant passage to connect the adjacent air bags in turn from one bag, the expansion is V-shaped air bag (7) (1) (8) (6) (2) (5), air port (14) and broken line (1) (2), (2) (3), (2) (4), (3) (5) and (4) (6); the positions of the fold lines in the bag are provided with constant channels (9), (10), (11), (12) and (13). At the fold line position in the bag, a support can be provided to partially support the two layers of bag films, and a common channel is formed beside the support. The maximum thickness of the inflation is 1.38x of the length of one side, and the inflation has a middle-range cylinder/piston combined function under the positive pressure condition and can be used for a solar low-temperature heat engine.

Description

Folding air bag

Technical Field

The folding air bag is an air bag type pneumatic component with an air port.

Background

Conventional vented pneumatic air bag modules are commonly used for jack-type pneumatic operation, typically in the form of a single-piece square bag. When the high-pressure air is inflated into the bag, the air bag is expanded, the thickness is increased, and the maximum thickness is equal to half of the length of one side. Generally, the folded airbag cannot be ventilated at the position of the folding line.

Disclosure of Invention

The folding air bag aims to improve the ratio of the thickness to the length of one side and has better performance.

This object is achieved in the following way:

six equilateral triangle air bags stacked together, there is a constant passage to connect the adjacent air bags in turn from one bag, the expansion is V-shaped air bag (7) (1) (8) (6) (2) (5), there are air ports (14) and broken lines (1) (2), (2) (3), (2) (4), (3) (5) and (4) (6); the fold line positions in the bag are provided with constant passages (9), (10), (11), (12) and (13).

The fold line position in the bag can be provided with a support for partially supporting the two layers of bag films, and a common channel is formed beside the support.

The support may be a flexible strip.

The flexible strip may be a string.

The maximum thickness of an equilateral triangle with a length of 1 per side is greater than the maximum thickness of a square bag with a length of 0.46 per side by 0.23. The maximum thickness of the folding air bag is 6x 0.23-1.38, and the lifting height is 2.76 times of that of the traditional square bag. Under the positive pressure condition, the solar energy low-temperature-difference heat engine has the combined function of a middle-range cylinder/piston, adapts to the angle change stroke, is light in weight and simple in structure, and can be used for replacing the cylinder/piston combination.

Fig. 6 is a schematic longitudinal sectional view of the folding air bag used for the V-axis swash plate type reciprocating variable rotation transmission device.

In the figure, items (7) (4) (8) (6) (2) (5) are V-shaped air bags, (1) (2), (2) (3), (2) (4), (3) (5) and (4) (6) are folding lines, (9), (10), (11), (12) and (13) are channels, (14) are air ports, (15) are loads, (16) are supports and (17) are folding air bags.

Detailed Description

Fig. 4 and 5 show the present folded air bag as a pneumatic module that reciprocates with air pressure, which is an application of a mid-stroke cylinder/piston. The folding air bag is suitable for a V-axis swash plate type reciprocating rotation transmission device, and is shown as a schematic diagram of a multi-bag type longitudinal section in figure 6.

The above-described transmission, in conjunction with a reciprocating mid-range cylinder/piston combination, is commonly used in solar thermal machines. The present folded air bag has the same function as the cylinder/piston in the case of low temperature difference, see fig. 6. One embodiment is that two groups of 3 folding air bags are respectively and averagely arranged on two sides of a V-axis plane, 6 folding air bags are arranged into a regular hexagon, air ports are respectively connected to power output pipes of 6 solar energy low-temperature difference heat engine units from left to outside, and the left section of the V-axis is a rotary output shaft.

The rest of the V-axis swash plate is the same as when using 6 reciprocating mid-stroke cylinder/piston combinations (two sets of 3 each mounted equally on both sides of the V-axis plane in a regular hexagon).
