Description

Technical Field

[0001] This invention relates to the field of footwear, and more specifically to a heated shoe and a method for processing the shoe. Background Technology

[0002] Most heated footwear products on the market use heating elements in the insole and rechargeable batteries embedded in the sole and heel for power. Heating in the insole or sole can cause sweating, and the heating wire system requires waterproofing, preventing the materials from wicking away sweat. Prolonged contact with sweat can lead to oxidation and short circuits; the battery embedded in the sole has limited space and its electromagnetic capacity is small, affecting battery life, and the constant pressure from the foot on the battery poses a safety risk. Currently, self-heating uppers are appearing in athletic shoes where the heating area covers the entire instep; this heating system is stretchable and bendable, and the power supply system uses a detachable structure. However, in existing heated upper technology, the power supply system is mounted on the outside of the shoe upper, which is aesthetically unappealing, has numerous and complex wiring, low integration, and is heavy. Furthermore, the power supply system is externally attached through an opening in the shoe upper, making it prone to slippage. Moreover, heated shoes are primarily used in extremely cold regions, requiring high waterproofing; currently, most use static waterproofing standards, which are not very effective.

[0016] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0017] In the first technical solution and related embodiments, the transmission device, which is fixedly connected to the surface of the shoe upper at the first opening, becomes an integral part of the shoe upper and has a flat and aesthetically pleasing appearance. The transmission device, as an integrated current and signal transmission device, has one end connected to the heating lining of the shoe upper and the other end detachably connected to the power supply device of the external shoe upper. At this time, the probe connects to the power supply device through the second opening, thus connecting the power supply device to the heating lining via the transmission device. The control module integrates the usage protocols of each circuit, controls the specific usage process and specifications of the entire power supply, and can automatically control whether to heat based on real-time temperature feedback from the temperature sensor in the shoe upper, thereby achieving intelligent temperature control. The overall structure is simple, easy to operate, and highly integrated.

[0018] In the second technical solution and related embodiments, carbon nanotube film is a nanomaterial with a special structure, mainly composed of single-layer to dozens of layers of coaxial cylindrical tubes with carbon atoms arranged in a hexagonal pattern. It is lightweight and has many exceptional mechanical, electrical and chemical properties. It has the characteristics of rapid, efficient and uniform heating. The thermal conductivity, electrical conductivity and current carrying capacity of carbon nanotubes are better than those of traditional heating fibers. Moreover, when carbon nanotube film is energized, it does not heat up linearly, but rather in a planar manner, with a larger heating area, doubled temperature, and uniform heating. It has better thermal conductivity, higher corrosion resistance and higher bending resistance, and can operate stably in harsh environments.

[0019] In the third technical solution and related embodiments, the power supply uses a low-temperature battery cell to store capacity and discharge. It can adapt to low-temperature environments. Compared with a normal-temperature battery cell, if the user goes to a low-temperature environment, the normal-temperature battery cell will not be able to discharge normally.

[0020] In the fourth technical solution and related embodiments, the temperature sensor is a negative temperature coefficient thermistor, or NTC thermistor for short. Its resistance changes with temperature, and the temperature change is calculated by measuring the change in resistance. When the temperature rises, the resistance of the NTC thermistor decreases. NTC thermistors are also used for temperature compensation in circuits. Electronic components experience changes in electrical performance due to temperature variations during operation, and NTC thermistors can be used to compensate for these changes. The NTC thermistor is primarily used to monitor temperature and transmit the signal to the control module, which then controls the power supply to turn the heating module on or off.

[0021] In the fifth technical solution and related embodiments, the flexible circuit board is connected to the power supply and control module, and a probe is connected through the second opening. The flexible circuit board transmits signals and current to the transmission device to complete the entire workflow.

[0022] In the sixth technical solution and related embodiments, the bottom shell is made of a thermoplastic plastic made of polycarbonate (PC) and polyacrylonitrile (ABS), referred to as PC / ABS engineering plastic. This material has both the excellent heat and weather resistance, dimensional stability and impact resistance of PC resin, and the excellent processing fluidity of ABS resin. The edges of the bottom shell are gradually tapered and thinned, which conforms to the characteristics of sewing and can be sewn together with the shoe upper, resulting in a flat and beautiful appearance.

[0023] In the seventh technical solution and related embodiments, the spring pin plate is mainly used for current transmission and signal transmission, transmitting current to the heating body to make it work at a specified temperature; the protective cover protects the connection line between the spring pin plate and the heating body, preventing the connection line from being loosened due to external interference.

[0024] In the eighth technical solution and related embodiments, when the conveying device and the power supply device are engaged by a snap-fit ​​and a slot, the ejector pin abuts against the power supply device via a probe, and the heating element is connected to the power supply device via the conveying device. The snap-fit ​​and slot connection method, along with the spring-loaded plate connection method, is ingeniously designed, structurally simple, and facilitates the installation of the power supply device. It also solves the problems of easy slippage and falling of the externally mounted power supply device, greatly improving the user experience and making it easier and more convenient to use.

[0025] In the ninth technical solution and related embodiments, when no external power supply device is attached, the outer cover protects the transmission device and the spring pin plate. At this time, the heated shoe can be used as an ordinary shoe.

[0026] In the tenth technical solution and related embodiments, the base fabric is made of polyester warp-knitted plain fabric, which has low elasticity and its main function is to serve as a protective layer for carbon nanotube films.

[0027] In the eleventh technical solution and related embodiments, in the processing method of the shoe, firstly, the heated inner lining is sewn to the waterproof material, and then joined with the first ribbed midsole to form the first inner boot, which is a heated inner cavity and also has a waterproof function; the upper and the midsole are sewn together to form a closed whole, which has a better waterproof effect; after the upper and the second ribbed midsole are joined, the discarded part needs to be removed, because it is two layers, and if it is not removed, it is easy for wrinkles to form inside, and the two layers will not fit together; in the processing method of the shoe, the heated inner lining and the two midsoles are combined to form a double-layer inner boot structure, which can achieve a dynamic waterproof level.

[0040] See Figures 1 to 3 , Figures 1 to 3 A heated shoe 1 is shown in an embodiment. For example... Figure 1 As shown, in this embodiment, the heated shoe 1 includes a shoe upper 2, a conveying device 3, a heated inner lining 4, and a power supply device 5.

[0041] like Figure 1 As shown, the upper part 2 of the shoe is provided with a shoe upper 21, and a first opening is provided on one side of the shoe upper 21; in this embodiment, the first opening is located on the outside of the shoe upper 21.

[0042] The transmission device 3 includes a bottom shell 31, a spring pin plate 32, a protective cover 33, and an outer cover. The transmission device 3 is an integrated current and signal transmission device; for example... Figure 1 and Figure 3 As shown, the conveying device 3 is adapted to the first opening and fixed to the upper 21 at the first opening; specifically, the bottom shell 31 is fixed to the surface of the upper 21 at the first opening; in this embodiment, the bottom shell 31 is made of a thermoplastic plastic composed of polycarbonate (PC) and polyacrylonitrile (ABS), referred to as PC / ABS engineering plastic; this material has both the excellent heat resistance, weather resistance, dimensional stability and impact resistance of PC resin, and the excellent processing fluidity of ABS resin; the edges of the bottom shell 31 are gradually tapered, and the edges are thinner, which conforms to the sewing characteristics and can be sewn together with the upper 21, resulting in a flat and beautiful appearance.

[0043] The conveying device 3 is provided with a plurality of probes 310 located in the first opening and facing outward, specifically, such as Figure 3 As shown, the bottom shell 31 is provided with a number of probes 310. The probes 310 are located on the surface of the bottom shell 31 and are arranged in a row along the horizontal direction of the shoe. A number of buckles 311 are arranged around the probes 310.

[0044] The protective cover 33 is detachably connected to the bottom shell 31, forming a cavity in the middle, where the spring pin plate 32 can be installed. The protective cover 33 has a third opening 330. The purpose of the protective cover 33 is to protect the connection line between the spring pin plate 32 and the heating inner lining 4, and to prevent the connection line from being loosened due to external interference.

[0045] The spring-loaded plate 32 is suitable for installation between the protective cover 33 and the bottom shell 31, and is mainly used for current transmission and signal transmission, transferring current to the heating element 42 to make it work at a specified temperature. Figure 3 As shown, one end of the spring plate 32 is electrically connected to the temperature sensor 43 through the third opening 330, and the other end is provided with a number of ejector pins 320 adapted to the probe 310, with the ejector pins 320 abutting against the probe 310.

[0046] The outer cover (not shown in the figure) has several grooves arranged circumferentially to fit the buckle 311, which is suitable for detachable connection with the bottom shell 31 when the power supply device 5 is not installed. When the power supply device 5 is not attached, the outer cover protects the transmission device 3 and the spring pin plate 32. At this time, the heated shoe 1 can be used as a regular shoe.

[0047] The heated inner lining 4 includes a lining fabric 41, a heating body 42, a bottom fabric 44, and a temperature sensor 43. The lining fabric 41 is attached to the inner surface of the upper 2 and contacts the foot. Specifically, since the lining fabric 41 is in contact with the foot, the material used needs to be warm, have good thermal conductivity, and be soft and comfortable. In this embodiment, for example... Figure 2 As shown, the lining 41 is in an inverted V shape that fits the instep and is laid along the toes to near the ankle.

[0048] The heating element 42 is mounted on the base fabric 44 and attached to the lining fabric 41; specifically, as shown in... Figure 2 As shown, the heating element 42 is a carbon nanotube film, which has several uniformly distributed carbon nanotube film units, and the carbon nanotube film units are electrically connected to each other. Carbon nanotube film is a nanomaterial with a special structure, mainly composed of single-layer to dozens of layers of coaxial cylindrical tubes formed by hexagonally arranged carbon atoms. It is lightweight and possesses many exceptional mechanical, electrical, and chemical properties. It exhibits rapid, efficient, and uniform heating characteristics. The thermal conductivity, electrical conductivity, and current carrying capacity of carbon nanotubes are superior to those of traditional heating fibers. Moreover, when energized, carbon nanotube films do not heat in a linear manner but in a planar manner, resulting in a larger heating area, doubled temperature, and more uniform heating. It also possesses better thermal conductivity, higher corrosion resistance, and higher bending resistance, enabling stable operation in harsh environments.

[0049] Base fabric 44, such as Figure 2 As shown, the heating body 42 is mounted on the base fabric 44 and attached to the lining fabric 41. Specifically, the base fabric 44 and the lining fabric 41 have the same shape, presenting an inverted V shape that fits the instep, and is laid along the toes to the vicinity of the ankle. In this embodiment, the base fabric 44 is made of polyester warp-knitted plain fabric, which has low elasticity and its main function is to serve as a protective layer for the carbon nanotube film.

[0050] Temperature sensor 43, one end of which is electrically connected to heating body 42, and the other end of which is electrically connected to transmission device 3; specifically, as shown in... Figure 2 and Figure 3 As shown, one end of the spring plate 32 in the conveying device 3 is connected to the temperature sensor 43. In this embodiment, the temperature sensor 43 is a negative temperature coefficient thermistor, or NTC thermistor for short. Its resistance value changes with temperature. The temperature change is calculated by measuring the change in resistance value. When the temperature rises, the resistance value of the NTC thermistor will decrease. NTC thermistors are also used for temperature compensation in circuits. Electronic components will experience changes in electrical performance due to temperature changes during operation, and NTC thermistors can be used to compensate for these changes. The NTC thermistor is mainly used to monitor temperature and transmit the signal to the control module 55. The control module 55 controls the power supply 52 to turn the heating module on or off.

[0071] The two green lights (39%-20%) are constantly on, while the other three indicator lights are off.

[0072] 19%-5% - One green light remains constantly on, while the other four indicator lights are off;

[0073] When the indicator light flashes rapidly (5%-3%), the other four indicator lights will turn off.

[0074] In this embodiment, the flashing mode has a flashing frequency of 1Hz; the fast flashing mode has a flashing frequency of 2Hz; and in the discharge mode, when the battery level reaches 3%, the output is turned off and the discharge stops after a 3-second delay.

[0075] The flexible circuit board 59 is connected to the power supply 52 and the control module 55, and is connected to the probe 310 through the second opening 560. The flexible circuit board 59 transmits signals and current to the transmission device 3 to complete the entire workflow.

[0076] The lower shell 56 mainly serves to protect the internal electronic components, power supply 52, and control module 55. It has a second opening 560, and the second opening 560 has a slot along the circumference that is compatible with the buckle 311.

In this embodiment, pressing the touch button 57, a long press turns on the power supply, which is the first level by default and is green; a short press switches to the second level and is blue; another short press switches to the third level and is red; finally, a long press turns off the power supply. On the other side of the touch button 57 is the charging hole 58. At this time, the elastic material on this side is attached to the lower shell 56, which is suitable for lifting the elastic material to expose the charging hole 58.

[0078] A shoe manufacturing method, such as Figure 4As shown, the procedure includes the following steps: preparing two midsoles, a first laminated midsole 6 and a second laminated midsole 7; gluing the heating element 42 and temperature sensor 43 to the bottom fabric 44 and attaching them to the lining fabric 41 to form a heated inner lining 4; sewing the heated inner lining 4 to a waterproof and breathable membrane, and then bonding it to the first laminated midsole 6 to form a first inner bootie 8, wherein the lining fabric 41 is in direct contact with the instep; waterproofing the stitching of the first inner bootie 8 to achieve a waterproof effect; and attaching the second laminated midsole 7 to the first laminated midsole 6. The second inner bootie 8 is sewn together with the upper using water-soluble thread. The second inner bootie 7 includes a reserved part 71 and a discarded part 72. The reserved part 71 is the part around the edge of the second inner bootie 7, and the discarded part 72 is the part of the second inner bootie 7 without the edge. The sewing line is the boundary line between the reserved part 71 and the discarded part 72. The first inner bootie 8 is sewn to the upper to complete the production of the entire upper. The completed upper is then bonded to the second inner bootie 7. Then, the water-soluble thread is dissolved in water, and the discarded part 72 is removed.

[0079] In this embodiment, the shoe manufacturing process involves first sewing the heated inner lining 4 with the waterproof material, and then joining it with the first ribbed midsole 6 to form the first inner boot 8, which is a heated inner cavity and also has a waterproof function. The upper and midsole are sewn together to form a closed whole, which has a better waterproof effect. After the upper and the second ribbed midsole 7 are joined, the discarded part 72 needs to be removed because it is a double layer. If it is not removed, it is easy for wrinkles to form inside, and the two layers will not fit together. In this shoe manufacturing process, the heated inner lining 4 is combined with the two midsoles to form a double-layer inner boot structure, which can achieve a dynamic waterproof level.

[0080] In this embodiment, the conveying device 3, which is sewn together with the surface of the shoe upper 21 at the first opening, becomes an integral part of the shoe upper 21, resulting in a flat and aesthetically pleasing appearance.
