Description

Technical Field

[0001] This utility model relates to the field of footwear, and in particular to a shoe that is easy to put on and take off. Background Technology

[0002] Most athletic and outdoor footwear products on the market today adopt a fixed structural design, relying primarily on traditional shoelaces, Velcro, or zippers for basic on / off and fit. However, in actual use, especially during outdoor activities such as hiking, mountaineering, and trail running, users often face complex situations such as foot swelling, terrain changes, and frequent putting on and taking off of shoes. The existing shoe structure is relatively simple and passive, making it difficult to achieve targeted dynamic adjustments. This not only affects the ease of wearing but also reduces the user's adaptability and comfort in complex environments. Especially regarding the "easy on and off" requirement, which is highly relevant to both daily life and outdoor activities, current footwear products lack a truly effective solution. While some smart shoe products attempt to introduce sensor modules to record data such as steps and trajectory, most only remain at the level of information monitoring and feedback, lacking structural physical response capabilities. Some products also use motors or mechanical devices to achieve shoe deformation, but due to the large size, weight, and poor comfort of these devices, the actual wearing experience is severely affected, hindering widespread application. Therefore, how to achieve quick on / off and active response adjustment of the shoe structure while ensuring good support and wearing comfort is an important technical problem that has not yet been solved in current footwear product design. Summary of the Invention

[0003] In order to solve the problems existing in the background art, the present invention provides a shoe that is easy to put on and take off.

[0004] The present invention adopts the following technical solution: a shoe that is easy to put on and take off, including a shoe body and an elastic telescopic mechanism; the elastic telescopic mechanism is disposed on the upper and heel of the shoe body, and an elastic stretch fabric is provided between the two elastic telescopic mechanisms, and the opening size of the shoe opening is controlled by the elastic telescopic movement of the two elastic telescopic mechanisms.

[0005] Furthermore, the elastic telescopic mechanism consists of an elastic skeleton, an elastic fabric, and a shoe spine; the elastic fabric is disposed between the ribs of the elastic skeleton; the shoe spine is connected through the elastic skeleton.

[0006] Furthermore, the sole of the shoe body is equipped with a pressure sensor, a control chip, a driver chip, and a battery; a switch is located on the outside of the shoe body; the switch is used to trigger the working state of the control chip and the pressure sensor; when turned on, it receives pressure signals and controls the output of the control chip according to the signals; the battery is equipped with a charging port for real-time charging; the control chip is an Arduino UNO based on ATmega328P, the pressure sensor is a C18.3-ST pressure sensor, and the driver chip is an IRF520 driver module.

[0007] Furthermore, the shoe spine is provided with shape memory alloy wires (SMA), which are spring-like. The two ends of the shape memory alloy wires (SMA) are fixed to the two ends of the elastic skeleton. When the shape memory alloy wires (SMA) in the shoe spine channel are energized, they will contract rapidly. While contracting, they will pull the elastic skeleton to contract. There are elastic fabrics between the elastic skeleton ribs, which will fold as the elastic skeleton contracts. This allows the elastic telescopic mechanism to be controlled by the characteristics of the shape memory alloy wires (SMA).

[0008] Furthermore, the pressure sensors are respectively installed at the heel and forefoot support points on the sole of the shoe. Based on the process of putting on / taking off shoes, pressure sensors are installed at essential points along the process. For example, when putting on shoes, the forefoot first probes into the shoe opening and presses against the heel of the sole. At this time, the pressure sensor at the heel of the sole receives a signal and sends it to the control chip. The control chip determines the behavior of putting on shoes based on the received signal and outputs control, energizing and contracting the shape memory alloy wire (SMA). This contraction causes the shoe spine to contract, tightening the elastic telescopic mechanism. As the elastic telescopic mechanisms at the upper and heel of the shoe tighten, the shoe opening widens, facilitating further insertion of the foot into the shoe, making it easier to put on.

[0009] Furthermore, the control chip is connected to the drive module, and the drive module is connected to the shape memory alloy wire; the pressure sensor is connected to the control chip; the switch on the outside of the shoe is connected to the control chip, and the control chip controls whether the shoe is working. The control chip is connected to the shape memory alloy wire (SMA) inside the shoe spine on the two elastic telescopic mechanisms, controls the power supply, and thus controls the extension and retraction of the elastic telescopic mechanisms.

[0010] The beneficial effects of this invention, which provides an easy-to-wear shoe, are that by setting elastic telescopic mechanisms at both the upper and heel to adjust the size of the shoe opening, it makes it more convenient to put on and take off shoes in daily life, especially when the feet are swollen and not suitable for normal shoe putting on and taking off. Furthermore, by incorporating controllable shape memory alloy (SMA) control into the elastic telescopic mechanism, it captures the characteristics of daily behavioral movements, realizes automatic opening and closing of the shoe body, and effectively improves the user's wearing experience and the level of intelligence of footwear products.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figure 1-3As shown, a shoe that is easy to put on and take off includes a shoe body 1 and an elastic telescopic mechanism 2. The elastic telescopic mechanism 2 is located on the upper and heel of the shoe body 1, and an elastic stretch fabric 13 is provided between the two elastic telescopic mechanisms 2. The elastic telescopic mechanism 2 is composed of an elastic skeleton 4, a shoe spine 5, and an elastic fabric 6. The elastic skeleton 4 is made of three-dimensional TPU material arranged in a rib-like shape, and the elastic fabric 6 is provided between the ribs. The shoe spine 5 connects all the ribs and is fixedly connected to the two ends of the elastic skeleton 4. Tightening the end of the shoe spine 5 can cause the elastic skeleton 4 to contract. At the same time, tightening the shoe spine 5 at the ends of the two elastic telescopic mechanisms 2 in the opposite direction can cause the elastic skeleton 4 on both sides to contract to the sides, stretching the elastic stretch fabric 13 in the middle, thereby widening the shoe opening. Example

[0023] like Figure 1-8 As shown, a shoe that is easy to put on and take off has a pressure sensor, an Arduino UNO control unit 11, and a battery 9 inside the sole of the shoe body 1; a switch 12 is located on the outside of the shoe body 1; the switch 12 is used to control the working status of the Arduino UNO control unit 11, the heel pressure sensor 7, and the foot pressure sensor 8; when turned on, it receives pressure signals and controls the output of the Arduino UNO control unit 11 according to the signals; the battery 9 has a charging port 10 for real-time charging.

[0024] The shoe spine 5 contains shape memory alloy wires (SMA), which are spring-like. The two ends of the shape memory alloy wires (SMA) are fixed to the two ends of the elastic skeleton 4. When the shape memory alloy wires (SMA) in the shoe spine 5 channel are energized, they will contract rapidly. While contracting, they will pull the elastic skeleton 4 to contract. There are elastic fabrics 6 between the ribs of the elastic skeleton 4, which will fold as the elastic skeleton 4 contracts. This allows the elastic telescopic mechanism 2 to be controlled by the characteristics of the shape memory alloy wires (SMA).

[0025] Pressure sensors are respectively installed at the heel and forefoot support points on the sole of the shoe. Based on the process of putting on / taking off shoes, pressure sensors are placed at essential points along the process. For example, when putting on shoes, the forefoot first enters the shoe opening and presses down on the heel. At this time, the heel pressure sensor 7 on the sole receives a signal and sends it to the Arduino UNO control unit 11. The Arduino UNO control unit 11 determines the received signal as the act of putting on shoes and outputs control, energizing and contracting the shape memory alloy wire (SMA). This contraction causes the shoe spine 5 to contract, tightening the elastic telescopic mechanism 2. As the elastic telescopic mechanisms 2 at the upper and heel of the shoe body 1 tighten, the shoe opening 3 widens, allowing the foot to continue into the shoe. When the entire foot is inside the shoe body 1, the forefoot pressure sensor 8 and the heel pressure sensor 7 simultaneously collect pressure signals. At this point, switch 12 is turned off, and the Arduino... When the UNO control unit 11 shuts off its output, the shape memory alloy wire (SMA) returns to its original shape, the elastic telescopic mechanism 2 returns to its original shape, and the enlarged shoe opening returns to its original shape, making it easy to put on. When it is necessary to take off the shoe, switch 12 is turned on again, the heel is slightly raised, and after the heel pressure sensor 7 detects that the pressure has decreased, the Arduino UNO control unit 11 outputs control, the shape memory alloy wire (SMA) is energized and retracts, and the shoe opening 3 is enlarged again. When the heel pressure sensor 7 and the foot pressure sensor 8 do not detect pressure signals at the same time, switch 12 is turned off, the Arduino UNO control unit 11 shuts off its output, the shape memory alloy wire (SMA) returns to its original shape, the elastic telescopic mechanism 2 returns to its original shape, and the enlarged shoe opening returns to its original shape.

[0026] The D9 and D10 ports of the Arduino UNO control unit 11 are connected to SIG1 and SIG2 respectively, serving as SIG signal ports. These ports control the power supply of the shape memory alloy wires (SMA) in the shoe spine 5 of the two elastic telescopic mechanisms 2 via the IRF520 driver module. The A0 and A1 ports of the Arduino UNO control unit 11 are connected to the heel pressure sensor 7 and the forefoot pressure sensor 8 respectively, detecting the current pressure status. The outer shoe switch 12 is connected to the D6 port of the Arduino UNO control unit 11 to control whether the chip is working.

[0027] The Arduino UNO control unit 11 outputs a high-level signal to the MOSFET module via a pin, controlling its on / off state and achieving precise control over the SMA wire's power supply. One end of the SMA wire is connected to the MOSFET output terminal V+, and the other end is connected to V-. The power supply is a 7.4V lithium battery pack, which provides sufficient drive power to allow the SMA to complete its deformation within 0.5 seconds. This short-time current switching strategy not only ensures fast response but also avoids performance degradation caused by material overheating.
