Dynamic pressure control air cushion device

The present invention relates to a dynamic pressure-controlled air cushion device, and more particularly to a dynamic pressure-controlled air cushion device that is inflated by gas pumping.

In general, the cushioning and support of the sole is a very important part of the footwear, which is more important for sports shoes or work shoes. For example, when the sole is not cushioned, the user may easily cause pain in the foot or knee during the movement or work of the footwear, which may cause the occurrence of plantar fasciitis; when the sole support is insufficient During the movement or work of the footwear, the user may easily cause sprained shoes or damaged shoes.

Most of the traditional footwear is filled with foam at the bottom, thereby providing support and cushioning of the user's foot, and can be set at a specific force application position according to the shape or force of the user's foot. Foam of different densities, thereby providing a user with a good footwear wearing experience. However, after the foam is generally worn for a period of time, it is easy to cause elastic loss of the foam, thereby losing the effect of suspension and support. In addition, according to the user's wearing habits, the user must first observe the habit of wearing shoes, and even need to use the testing equipment to obtain the relevant information of the foot pressure. This process will result in manufacturing cost, time and manpower. The waste is not friendly to some people with high arches or flat feet, and it also leads to the possibility of danger after wearing.

Among the commercially available shoes, some shoes are placed on the sole with air cushions, rubber pads or spring pieces to provide cushioning and support. However, these shoes cannot adjust the air cushion according to the user's wearing requirements. The pressure inside the rubber pad can not only meet the needs of each person's different foot types and usage habits, nor provide comfortable wearing feet.

Please refer to FIG. 7. FIG. 7 is a schematic cross-sectional view showing the first gas pump shown in FIGS. 5A and 5B. As shown in the figure, the first gas pump 12 of the present invention is sequentially composed of a cover plate 126, an insulating sheet 1242, a conductive sheet 125, an insulating sheet 1241, a piezoelectric actuator 123, a resonator piece 122, and the like from top to bottom. After being stacked, the piezoelectric actuator 123, the insulating sheet 1241, the conductive sheet 125, and the other insulating sheet 1242 are laminated to form a colloid 218, thereby filling the periphery of the accommodating space 126a of the cover 126. And complete the seal. After the assembly, the first gas pump 12 is a quadrilateral structure, but it is not limited thereto, and its shape may be changed according to actual needs. In addition, in the embodiment, only the conductive pins 1251 (not shown) of the conductive sheet 125 and the conductive pins 1232b of the piezoelectric actuator 123 (shown in FIG. 8A ) are protruded from the cover 126 . In addition, it is convenient to connect to an external power supply, but it is not limited to this. The assembled first gas pump 12 forms a first chamber 127b between the cover plate 126 and the resonant plate 122.

In this embodiment, the resonator piece 122 of the first gas pump 12 of the present invention has a gap g0 between the piezoelectric actuator 123 and the conductive material, for example, conductive adhesive, but not To this end, the resonance piece 122 and the convex portion 1231e of the suspension plate 1231 of the piezoelectric actuator 123 are maintained at a depth of a gap g0, thereby guiding the airflow to flow more rapidly, and the suspension plate is suspended. The convex portion 1231e of the 1231 is kept at an appropriate distance from the resonant plate 122 to reduce the mutual contact interference, thereby causing the noise to decrease. In other embodiments, the height of the outer frame 1232 can be increased by applying the high voltage electric actuator 123. When it is assembled with the resonator piece 122, a gap is added, but it is not limited thereto. Thereby, when the piezoelectric actuator 123 is driven to perform the air collecting operation, the gas system is first collected by the opening portion 1263 of the cover plate 126 to the confluence chamber 127a, and further flows through the hollow hole 1220 of the resonance piece 122 to the first A chamber 127b is temporarily stored. When the piezoelectric actuator 123 is driven to perform an exhaust operation, the gas system first flows from the first chamber 127b through the hollow hole 1220 of the resonator 122 to the confluence chamber 127a, and the gas is supplied. The shoelace airbag 10 is introduced into the tongue airbag 11.

The operation flow of the first gas pump 12 in the present case is further described below. Please refer to FIG. 8A to FIG. 8D simultaneously. FIGS. 8A-8D are schematic diagrams showing the operation process of the first gas pump in the preferred embodiment of the present invention. First, as shown in FIG. 8A, the first gas pump 12 is structured as described above by the cover plate 126, the other insulating sheet 1242, the conductive sheet 125, the insulating sheet 1241, the piezoelectric actuator 123, and the resonance. The sheet 122 is assembled and positioned, and has a gap g0 between the resonator piece 122 and the piezoelectric actuator 123, and the resonance piece 122 and the side wall 1261 of the cover plate 126 jointly define the confluence chamber 127a on the resonance piece. There is a first chamber 127b between the 122 and the piezoelectric actuator 123. When the first gas pump 12 has not been driven by voltage, the position of each element is as shown in Fig. 8A.

Next, as shown in FIG. 8B, when the piezoelectric actuator 123 of the first gas pump 12 is vibrated upward by the voltage, the gas enters the first gas pump 12 from the opening 1263 of the cover plate 126. And is collected into the confluence chamber 127a, and then flows upward into the first chamber 127b via the hollow hole 1220 on the resonator piece 122, and the resonance piece 122 is affected by the resonance of the suspension plate 1231 of the piezoelectric actuator 123. The reciprocating vibration is performed, that is, the resonance piece 122 is deformed upward, that is, the resonance piece 122 is slightly convex upward at the hollow hole 1220.

Thereafter, as shown in FIG. 8C, at this time, the piezoelectric actuator 123 is vibrated downward to the initial position, at which time the floating portion 1231e of the suspension plate 1231 of the piezoelectric actuator 123 is close to the resonance plate 122. The micro-convex portion is upwardly raised at the hollow hole 1220, thereby causing the gas in the first gas pump 12 to be temporarily stored in the upper first chamber 127b.

Further, as shown in FIG. 8D, the piezoelectric actuator 123 vibrates downward again, and the resonance piece 122 is vibrated by the vibration of the piezoelectric actuator 123, and the resonance piece 122 is also vibrated downward. The downward deformation of the resonator piece 122 compresses the volume of the first chamber 127b, thereby causing the gas in the upper half of the first chamber 127b to push to flow to both sides and through the gap 1234 of the piezoelectric actuator 123 to circulate downward. The compressed air is discharged to the hollow hole 1220 of the resonator piece 122 to form a compressed gas flowing through the air guiding end opening 204 to the first guiding cavity 202 of the carrier 20. It can be seen from this embodiment that when the resonant plate 122 performs vertical reciprocating vibration, it can be increased by the gap g0 between the resonant piece 122 and the piezoelectric actuator 123 to increase the maximum distance of its vertical displacement, in other words, The gap g0 provided between the vibrating plate 12 and the piezoelectric actuator 123 allows the resonance piece 122 to generate a larger displacement up and down when it resonates.

Finally, the resonator piece 122 will return to the initial position, that is, as shown in FIG. 8A, and then continue to circulate in the order of FIG. 8A to FIG. 8D through the above-described operation flow, and the gas will continuously pass through the opening portion 1263 of the cover plate 126.
