Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-4 The present invention provides a technical solution: an automatically inflatable and deflated airbag shoe, including a sole 1;

[0033] Upper 2 and sole 1 are glued to the bottom of upper 2;

[0034] The air bladder 3 is glued to the upper 2 by the heat-sealed edge 301;

[0035] The air bladder 3 is attached to the upper 2 by heat pressing, and a heat-sealed edge 301 is formed on the edge of the air bladder 3. The middle part of the air bladder 3 is in contact with the upper 2.

[0036] When in use, the air bladder 3 can inflate and expand, supporting the shoe upper 2 in the middle, which can tighten and fix the shoe to the wearer's foot.

[0037] The inflatable cover 4 is detachably snapped onto the heel of the shoe upper 2.

[0038] The inflatable cover 4 is a flexible rubber cover with an arc-shaped structure, and the inner arc side of the inflatable cover 4 is attached to the heel of the shoe upper 2.

[0039] During operation, the flexible rubber inflatable cover 4 can elastically deform and change appropriately with the shoe upper 2.

[0040] Furthermore, the two ends of the inflatable cover 4 are engaged with the heel edge of the sole 1 to form an engaging mounting part. The engaging mounting part includes plastic strips 5 symmetrically arranged on the edge of the sole 1. The bottom of the plastic strips 5 is fixedly connected to the edge of the sole 1, and the upper end of the plastic strips 5 protrudes. A slot 501 for engaging and connecting the inflatable cover 4 is provided on the outer side of the end of the plastic strips 5 facing the inflatable cover 4.

[0041] A flexible plastic strip 5 is set on each side of the heel edge of the sole 1, corresponding to the two ends of the air cover 4. The two plastic strips 5 serve as connecting ends to facilitate the installation of the air cover 4, and can also flexibly change with the shoe body to avoid hard obstruction.

[0042] Both ends of the inflatable cover 4 are equipped with recessed locking plates 401 that fit into the slots 501 of the plastic strip 5. One side of each locking plate 401 is attached to the inner and outer plates of the slot 501 without protruding. A first connecting hole 402 and a second connecting hole 502 are respectively opened on each set of locking plates 401 and slots 501. Each set of first connecting holes 402 and second connecting holes 502 is fastened with screws, which makes the inflatable cover 4 quick and easy to detach and install at the heel of the shoe.

[0043] Furthermore, the cover of the inflatable cover 4 has recessed edges 403 at both ends of the mounting portion. The inflation tube 302 extending from the inflatable bladder 3 is inserted through one end of the recessed edge 403. The insertion end of the inflation tube 302 is connected to the automatic inflation and deflation structure provided inside the inflatable cover 4, and the inflation and deflation control the inflation and expansion of the inflatable bladder 3.

[0044] The inflation tube 302 is located on the side of the airbag 3 and is close to the concave edge 403 at the end of the inflation cover 4. This allows the inflation tube 302 to be flexibly connected to the concave edge 403 of the inflation cover 4 after the inflation cover 4 is quickly installed, so that the airbag 3 can be connected to the inflation cover 4 for automatic inflation and deflation control.

[0045] The automatic inflation / deflation structure includes an air supply chamber 405 opened inside the inflation cover 4, a flexible circuit board 406 fixedly connected inside the air supply chamber 405, and a power supply battery holder 407 provided on one side of the flexible circuit board 406.

[0046] It should be noted that the battery holder 407 is embedded in the inner arc side of the air cover 4, the opening of the battery holder 407 is exposed in the air cover 4, and a button cell battery 408 is filled in the battery holder 407. A detachable waterproof adhesive sticker 409 is attached to the inner wall of the air cover 4 in the end area of ​​the battery holder 407.

[0047] In specific implementation, the push cover at the end of the battery holder 407 is opened (a conventional method in the prior art, such as the push cover of the battery installation part of the remote control), the button dry cell battery 408 is inserted into the battery holder 407 to supply power to the flexible circuit board 406, and the end of the battery holder 407 is covered with waterproof adhesive tape 409. The battery holder 407 located here can prevent water, dust and other substances from entering, so as to facilitate the cleaning and maintenance of the air cover 4 and the safe arrangement of the power supply part.

[0048] To facilitate the inflation and deflation control of the airbag 3, as well as the waterproofing of the air supply structure and the cleaning of the inflation cover 4:

[0049] One side of the flexible circuit board 406 is electrically connected to an air pump 4010 via wires. The air pump 4010 is a miniature air pump. A miniature air pump is a gas delivery device that is small in size, uses gas as the working medium, and is mainly used for various purposes such as gas sampling, gas circulation, vacuum adsorption, vacuum pressure holding, evacuation, inflation, and pressurization. In this embodiment, it is an inflation type. The body of the air pump 4010 is fixedly embedded in the air supply chamber 405 near the inflation pipe 302. The air delivery end of the air pump 4010 is detachably connected to the inflation pipe 302 and the inflation and deflation are controlled.

[0050] It should be noted that: an air supply pipe 404 is embedded in the concave edge 403 of the air tube 302, which is connected to the air supply chamber 405. Two symmetrically arranged annular second limiting plates 4014 are fixedly connected inside the air supply pipe 404. A second waterproof and breathable sheet 4015 is filled between the two second limiting plates 4014. Two symmetrically arranged annular third limiting plates 303 are fixedly connected on the air tube 302. A movable limiting threaded cap 304 is movably sleeved on the tube body between the two third limiting plates 303. One end of the air supply pipe 404 protrudes from the concave edge 403, and the protruding end of the air supply pipe 404 is threadedly connected to the threaded cap 304 and is tightly connected to the air tube 302.

[0051] The inflation tube 302 is detachably threadedly connected to the air supply tube 404 through the threaded cap 304 that limits rotation, so that the inflation cap 4 on the shoe body can be flexibly connected to the inflation bladder 3 when assembled; at the same time, the air supply tube 404 is connected to the air supply chamber 405 through the internally limited and stable second waterproof and breathable sheet 4015. That is, in the only channel connecting the inflation tube 302 to the air supply chamber 405, the second waterproof and breathable sheet 4015 is used to block water and allow air to pass through the channel, so there is no need to worry about water or foreign objects entering the air supply chamber 405 through the connection channel of the inflation tube 302 and affecting the automatic air supply components.

[0052] The air outlet of the air pump 4010 is connected to the port of the air supply pipe 404 located in the air supply chamber 405 via a flexible air tube. An air inlet pipe 4011 is embedded in the wall of the air supply chamber 405 near the air pump 4010. A first waterproof and breathable sheet 4012 is fixedly glued to the port of the air inlet pipe 4011 near the outside. An annular first limiting piece 4013 is fixedly connected to the inner wall of the air inlet pipe 4011. The first limiting piece 4013 is abutted and supported against the side of the first waterproof and breathable sheet 4012 near the air supply chamber 405. The air outlet of the air pump 4010 is connected to the port of the air supply chamber 405 via a flexible air tube.

[0053] The air inlet pipe 4011 with a first waterproof and breathable sheet 4012, the air pump 4010, and the air delivery pipe 404 are combined to form a structure that can draw in outside air in a liquid-resistant manner to supply air to the inflatable bladder 3. The waterproof and breathable sheets are stabilized within their respective pipes by limiting plates, improving the stability of the air supply operation. This also ensures that when arranging the air supply structure of the air pump 4010, there is no need to worry about water or foreign matter entering the air supply chamber 405 through the gas channel and affecting the automatic air supply components.

[0054] In this embodiment, to facilitate flexible deflation control after inflation:

[0055] An air supply chamber 405 between the air pump 4010 and the air supply pipe 404 is inlaid with an air release pipe 4016 that connects to the chamber. The air outlet of the air pump 4010 is connected to a branch pipe of a flexible air tube to connect to the air release pipe 4016. A third waterproof and breathable sheet 4017 is fixedly glued to the end of the air release pipe 4016 near the outside. A solenoid valve 4018 for opening and closing and controlling the air release of the inflatable bag 3 is installed on the pipe between the other end of the air release pipe 4016 and the third waterproof and breathable sheet 4017. One end of the solenoid valve 4018 is electrically connected to the flexible circuit board 406 through a wire.

[0056] After the air pump 4010 inflates, when the user needs to deflate and adjust the airbag 3, the airbag 3 is connected to the outside world by opening the solenoid valve 4018 and a certain degree of deflation is performed. The inflation of the airbag 3 can be flexibly controlled, and the restraining effect brought by the inflation of the airbag 3 can be appropriately adjusted so that the shoes can be worn. At the same time, the deflation tube 4016 is also protected by a third waterproof and breathable sheet 4017 to prevent liquid from entering the air supply chamber 405 and affecting the automatic air supply components. The airbag 4 can be cleaned directly on the shoe body or removed separately for overall cleaning, which is convenient to use.

[0057] In this embodiment, the first waterproof and breathable sheet 4012, the second waterproof and breathable sheet 4015, and the third waterproof and breathable sheet 4017 are all configured as hydrophobic and breathable polytetrafluoroethylene membranes.

[0058] Please refer to the following: Figure 5-6 A control method for an automatically inflatable and deflated airbag shoe is disclosed. The flexible circuit board 406 includes a Bluetooth module, an inflation control module for controlling the duration of inflation, and a start-up module for controlling the opening and closing of an air pump 4010 and a solenoid valve 4018. A corresponding app is also provided in conjunction with the flexible circuit board 406. The app also includes a Bluetooth module that wirelessly matches the flexible circuit board 406, as well as the matching inflation control module and start-up module. The inflation control module in the app presets the inflation duration of the air pump 4010, i.e., controls the working time of the air pump 4010 via the flexible circuit board 406. Inflation stops after the preset duration (this is a very common technique where the pump stops working after a preset time, and will not be elaborated further). The start-up module in the flexible circuit board 406 includes options to start the air pump unit and the solenoid valve unit. The start-up module in the app includes on / off options for starting the air pump and the solenoid valve, and wirelessly remotely controls the start of the air pump unit and the solenoid valve unit.

[0059] In use, the air pump unit is wirelessly started by touching the air pump switch, so that the air pump 4010 automatically inflates the airbag 3 within a predetermined time and then stops. When the user needs to adjust the inflation degree of the airbag 3 to deflate it, the solenoid valve unit is wirelessly started by touching the solenoid valve switch, so that the solenoid valve 4018 opens, and the airbag 3 connects to the outside world to deflate. Touching the solenoid valve switch again closes it, thus automating the inflation and deflation of the airbag 3.
