Description

Automatic inflatable cushion system for shoes

The present invention relates to an automatic inflatable cushion system for shoes, and more particularly to an automatic inflatable cushion system for shoes which is inflated by gas pumping.

In general, most conventional footwear uses lace as a tool for loosening and securing the foot, however, footwear with laces can have many problems in wearing. For example, when the shoelace is detached during the wearing process, the shoelace must be re-fastened to continue the activity, resulting in inconvenience and waste of time. Furthermore, wearing footwear with laces is also potentially dangerous. For example, when the shoelace is inadvertently released, it is easy to cause another person to step on it and trip over. It may also be caught in the gap of the automatic escalator, bicycle chain or motorcycle foot bolt, etc., which may cause accidents. In addition, wearing footwear with laces for a long time tends to exert excessive pressure on the foot, resulting in discomfort to the wearer.

A small number of traditional footwear is used as a tool for loosening and fixing the foot in other ways, such as a devil felt or a sock-type shoe body. However, the devil's felt is insufficiently fixed and easy to fall off, and the long-term use makes the devil's felt felt sticky. Falling, causing inconvenience in activities, is also not suitable for sports wear. The sock-type shoe body is not sufficient for the fixation of the foot, and the elastic adjustment cannot be performed according to the demand. The long-term use is also likely to cause the sock-type shoe body to be slack, and the demand for the fixed foot cannot be satisfied.

On the other hand, the general traditional footwear can only be selected according to the corresponding size of the length of the foot, but this does not meet the needs of the shape of each person's foot. When the foot is relative to the shoes worn by the footwear When the width of the body is too wide or too narrow, or the height of the shoe is too high or too flat, it is easy to cause discomfort in the foot, and it is more likely to cause injury during the activity.

In view of this, how to develop a kind of automatic inflatable cushion system for shoes that can be adapted to the shape of an individual's foot and can be comfortably covered and fixed to the foot is developed. The problem that needs to be solved.

The main purpose of the present invention is to provide an automatic inflatable cushion system for shoes, which can be applied to various footwears, and can inflate the inflatable cushions of the automatic inflatable cushion system to fit closely with the user's foot. The individual's foot shape is adjusted and can be comfortably wrapped to secure the foot.

Another main purpose of the present invention is to provide an automatic inflatable cushion system for shoes, which has a gas pressure adjusting function, which can automatically adjust the internal air pressure according to the state of use, can prolong the service life of the inflatable cushion, and can also wear the shoes under the most comfortable pressure. .

In order to achieve the above object, one of the more broad aspects of the present invention provides a system for automatically using an inflatable cushion for shoes, which is suitable for shoes, the shoe includes a shoe body and a bottom, and the shoe body is connected to the bottom to jointly define a wearing space, and An opening for communicating with the wearing space, the automatic inflatable cushion system for shoes comprises: an inflatable cushion disposed in the shoe body; a gas passage disposed between the inflatable cushion and the shoe body and connected to the inflatable cushion; gas pumping, Connected to the gas passage; a weight sensor disposed at the bottom; a pneumatic sensor disposed in the gas passage; and a control module electrically connected to the gas pump, the weight sensor, and the barometric sensor; When the weight sensor senses the weight generation, the weight sensor sends an enable signal to the control module, and the control module drives the gas pump to act according to the enable signal, so that the gas is introduced into the inflatable cushion via the gas passage to make the charge The air cushion is filled with gas to generate expansion. When the air pressure sensor senses that the internal pressure of the air cushion is higher than a certain threshold interval, the air pressure sensor sends a disable signal to the control mode. The control module controls the gas pump to stop according to the disable signal.

7A to 7E are flow chart diagrams of the gas pumping operation shown in Figs. 4A and 4B. Please refer to Fig. 6 and Fig. 7A to Fig. 7E. The operation flow of the gas pump in this case is briefly described as follows. When the gas pump 12 is actuated, the piezoelectric actuator 123 is biased by the voltage and is reciprocatingly vibrating in the vertical direction with the holder 1233 as a fulcrum. As shown in FIG. 7A, when the piezoelectric actuator 123 is vibrated downward by voltage, since the resonator piece 122 is a light and thin sheet-like structure, when the piezoelectric actuator 123 vibrates, The resonance piece 122 also resonates to reciprocate vertically, that is, the portion of the resonance piece 122 corresponding to the central concave portion 121c is also deformed by bending vibration, that is, the portion corresponding to the central concave portion 121c is movable of the resonance piece 122. In the portion 122a, when the piezoelectric actuator 123 is bent downward, the movable portion 122a of the resonator piece 122 corresponding to the central recess 121c is driven by the introduction and pushing of the gas and the vibration of the piezoelectric actuator 123. And as the piezoelectric actuator 123 is bent and vibrated downward, the gas enters through at least one air inlet hole 121a on the air intake plate 121, and passes through at least one bus bar hole 121b to be collected at the central central recess 121c. Then, the hollow hole 122c corresponding to the central recess 121c on the resonator piece 122 flows downward into the first chamber 120. Thereafter, due to the vibration of the piezoelectric actuator 123, the resonator piece 122 also resonates to perform vertical reciprocating vibration. As shown in FIG. 7B, the movable portion 122a of the resonator piece 122 is also followed. The vibration is downwardly slid and adhered to the convex portion 1231a of the suspension plate 1231 of the piezoelectric actuator 123 to make the convergence between the region other than the convex portion 1231a of the suspension plate 1231 and the fixed portion 122b on both sides of the resonance piece 122. The spacing of the chambers does not become small, and the resonant plate 122 is thereby The deformation is performed to compress the volume of the first chamber 120, and close the intermediate flow space of the first chamber 120, so that the gas in the chamber is pushed to flow to both sides, and then passes between the brackets 1233 of the piezoelectric actuator 123. The gap 1235 flows downward through the flow. Thereafter, as shown in FIG. 7C, the movable portion 122a of the resonator piece 122 is bent and vibrated upward to return to the initial position, and the piezoelectric actuator 123 is driven by the voltage to vibrate upward, so that the first chamber 120 is also pressed. The volume, but at this time, since the piezoelectric actuator 123 is lifted upward, the gas in the first chamber 120 flows toward both sides, and the gas continuously flows from at least one air inlet 121a on the air inlet plate 121. Upon entering, it flows into the chamber formed by the central recess 121c. Thereafter, as shown in FIG. 7D, the resonator piece 122 is resonated upward by the upward vibration of the piezoelectric actuator 123, and the movable portion 122a of the resonator piece 122 is also vibrated upward, thereby slowing down the gas continuously. At least one intake hole 121a of the gas plate 121 enters and flows into the chamber formed by the central recess 121c. Finally, as shown in FIG. 7E, the movable portion 122a of the resonator piece 122 also returns to the initial position. From this embodiment, it can be seen that when the resonator piece 122 performs vertical reciprocating vibration, it can be used with the piezoelectric actuator. The gap h between 123 is increased by the maximum distance of its vertical displacement. In other words, the provision of the gap h between the two structures allows the resonator piece 122 to generate a larger vertical displacement when resonating. Therefore, a pressure gradient is generated in the flow channel design of the gas pump 12, so that the gas flows at a high speed, and the gas is transmitted from the suction end to the discharge end through the difference in impedance of the flow path in and out of the flow path to complete the gas transfer operation. Even if there is air pressure at the discharge end, there is still the ability to continuously push the gas into the gas passage 13, and the effect of mute can be achieved, so that the gas pump 12 of FIG. 7A to 7E is repeated to operate, so that the gas can be pumped. 12 produces a gas transfer from the outside to the inside.

As described above, through the operation of the gas pump 12, the gas is introduced into the gas passage 13, the introduced gas flows into the inflatable cushion 11, and the inflatable cushion 11 is inflated to fit the surface of the wearer's foot, thereby The sneaker 2 can be attached tightly and securely to the user's foot, thereby providing sufficient support and protection for safe and comfortable wear.

In summary, the present invention provides an automatic inflatable cushion system for shoes, which can be applied to a sneaker, and the weight of the automatic air cushion system for the shoe is applied to the weight of the user's foot to make the automatic inflatable cushion for the shoe. The system automatically and intelligently inflates the inflatable cushion, and inflates the inflatable cushion to be closely attached to the user's foot, and can be adjusted according to the shape of the individual's foot, and can comfortably cover and fix the foot while providing sufficient Supportive and protective. In addition, the automatic air cushion system for shoes has a gas pressure adjustment function, which can automatically and intelligently adjust the internal air pressure according to the state of use, not only prolonging the service life of the air cushion, but also allowing the user to wear the shoes under the most comfortable pressure. In addition, the user can manually adjust the internal pressure of the inflatable cushion to provide more convenient operation and wider application.

This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application.
