Internal communication. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood on a case-by-case basis.

In the embodiment provided by the present invention, the present invention is described by taking the elderly as an example, since the fall of the elderly is very common and the fall of the elderly is the greatest damage to the body. It can be understood that the health shoe and control system provided by the present invention for preventing falls in the elderly can also be applied to children, mentally handicapped persons, patients or any other people who need to protect against falls.

As shown in FIG. 1, FIG. 1 is a schematic structural view of a preferred embodiment of a health shoe for preventing falls in the elderly according to the present invention. In the present embodiment, the health shoe 1 includes, but is not limited to, a sole 10, a sole 11, a sole 12, and a fall prevention device 2 disposed between the sole 10 and the sole 11 . In the present embodiment, a concave space is formed between the sole 10 and the sole plate 11, and the fall prevention device 2 can be completely built in the concave space formed between the sole 10 and the sole plate 11. In Fig. 1, the health shoe 1 shows only the sole portion consisting of the sole 10, the sole 11 and the sole 12, while the upper portion is not shown in Fig. 1. Wherein, the sole 10 refers to the upper surface of the sole in contact with the sole of the foot, the sole 11 refers to the lower surface of the sole in contact with the ground, and the sole 12 refers to the surrounding portion of the sole 10 and the sole 11 forming the sole. It can be understood that the sole 10, the sole 11 and the sole 12 of the present invention can adopt materials and structures similar to those of the ordinary shoes, which are not specifically limited in the present invention. In addition, the two left and right feet of the elderly need to wear the two health shoes 1 provided by the present invention. The embodiment of the present invention is described by taking only one health shoe 1 as an example.

The fall prevention device 2 includes, but is not limited to, a pressure sensor 20, a signal receiver 21, a microcontroller 22, a driver 23, a balance wheel 24, and a micro battery 25. The pressure sensor 20, the signal receiver 21, the driver 23 and the micro battery 25 are electrically connected to the microcontroller 22, respectively, and the balance wheel 24 forms a mechanical connection with the driver 23. In the present embodiment, the balance wheel 24 is mounted in the recess 13 on both sides of the sole 12 by the driver 23, and each of the health shoes 1 includes two balance wheels 24, respectively located on the sides of the sole 12 13 inside. Preferably, the position of the groove 13 is provided at an intermediate position on both sides of the sole 12 of the sole. When the elderly person wears the health shoe 1 normally without being in the pre-fall state (ie, when the balance wheel 24 is not driven), the balance wheel 24 is just built into the groove 13 on both sides of the sole 12, and does not affect The elderly wear healthy shoes 1 normal walking action.

Referring to Figure 2, Figure 2 is a perspective view of a preferred embodiment of a preferred embodiment of a health shoe for preventing falls in the elderly. When the elderly person falls pre-fall, the driver 23 drives the balance wheel 24 to be ejected from the groove 13 on both sides of the sole 12 to slide the health shoe 1 toward the human body in the pre-fall direction to balance the body center of gravity of the elderly to prevent The elderly fell.

Referring to Figure 3, Figure 3 is a signal flow diagram of a preferred embodiment of a control system for use in a health shoe for preventing falls in the elderly. In the present embodiment, the control system 100 includes a fall detection device 3 for setting the waist position of the elderly and a fall prevention device 2 disposed between the sole surface and the sole plate. For those skilled in the art, the acceleration and tilt angle of the human waist position can accurately determine whether the human body is pre-falling, so the fall detection device 3 can be installed or integrated in the waist position of the elderly (for example, the elderly wear On the belt).

The fall detection device 3 includes an acceleration sensor 31, a tilt sensor 32, and a signal transmitter 33. The acceleration sensor 31 and the tilt sensor 32 are electrically connected to the signal transmitter 33, respectively. The acceleration sensor 31 is configured to detect a human body acceleration signal of an elderly person in real time, and send the human body acceleration signal to the signal transmitter 33. The tilt sensor 32 is configured to detect a human body tilt signal of an elderly person in real time, and send the human body tilt signal to the signal transmitter 33. The signal transmitter 33 wirelessly transmits (for example, Bluetooth) the human body acceleration signal and the human body tilt signal to the signal receiver 21 of the fall prevention device 2.

When the signal receiver 21 receives the human body acceleration signal and the human body tilt signal transmitted by the signal transmitter 33 of the fall detection device 3, the human body acceleration signal and the human body tilt signal are transmitted to the microcontroller 22. The microcontroller 22 is a microprocessor, an MCU, or an electric control chip having basic data processing and data control functions, and the microcontroller 22 can process the human body acceleration signal and the human body tilt signal and determine Whether the elderly are in a pre-fall state.

In the present embodiment, since the acceleration threshold of the elderly is between 5 and 7 m/s under normal conditions, the inclination threshold is between 65 and 75 degrees. Among them, the inclination of the human body is defined as the angle between the human body and the horizontal plane. The human body stands at about 90° when standing, and about 0° when lying flat. When the microcontroller 22 detects that the human body acceleration is greater than the acceleration threshold and the human body tilt angle is less than the tilt angle threshold, the microcontroller 22 determines that the elderly person is in a pre-fall state, that is, the fall of the elderly is unavoidable. It can be understood that the human body acceleration signal and the human body tilt signal collected by the acceleration sensor 31 and the tilt sensor 32 are processed by the microcontroller 22 and the posture state of the human body is recognized, so that the elderly can be accurately predicted. Whether people fall or not increases the reliability of predicting falls in the elderly.

Referring to FIG. 4, FIG. 4 is a schematic diagram of a three-dimensional coordinate system required by the control system in the health shoe for preventing falls in the elderly to recognize the pre-fall state of the human body. In this embodiment, the three-dimensional coordinate system XYZ is first established with the waist position of the human body wearing the fall detection device 3 as an origin, and the angle between the human body and the horizontal plane is defined in the three-dimensional coordinate system XYZ to define the pre-fall direction of the human body. The rules are stored in the microcontroller 22. For example, when the angle between the human body and the X-axis is defined to be between 0° and 65°, the microcontroller 22 determines that the human body falls to the right; the angle between the human body and the X-axis is defined to be between 105° and 180°. When the microcontroller 22 determines that the human body falls to the left; when the angle between the human body and the Z axis is between 0° and 65°, the microcontroller 22 determines that the human body falls forward and defines the clip formed by the human body and the Z axis. When the angular range is between 105° and 180°, the microcontroller 22 determines that the human body has fallen backwards. According to the above rule of the human body pre-fall direction, the microcontroller 22 can recognize the pre-fall direction of the human body according to the human body inclination signal, including falling forward, falling backward, falling to the left, or falling to the right.

Referring to FIG. 3, the pressure sensor 20 senses the sole pressure signal of each foot of the elderly in real time, and sends the sole pressure signal of each foot to the microcontroller 22. The microcontroller 22 can determine the one foot of the elderly based on the sole pressure signal (ie, which foot needs to step, including the left foot step or the right foot step) requiring a step to balance the body center of gravity to prevent a fall. The embodiment of the invention utilizes the principle that the human body single foot steps to balance the weight of the human body to prevent the human body from falling. When the left foot pressure is much greater than the right foot pressure, the elderly need the left foot to move toward the human body in the pre-fall direction; when the right foot pressure is much greater than When the left foot is under pressure, the elderly need to move their right foot toward the human body in the direction of pre-fall.

When the elderly person falls pre-fall, the microcontroller 22 generates a direction control signal according to the pre-fall direction of the human body, and opens the driver 23 in the health shoe 1 worn by the determined one foot according to the sole pressure signal to make the balance wheel 24 The groove 13 on both sides of the sole 12 is ejected, and the driver 23 controls the balance wheel 24 to slide toward the human body in the direction of the fall in accordance with the direction control signal generated by the microcontroller 22, so that the elderly can balance the body center of gravity to prevent the elderly from falling. .

In the present embodiment, when the elderly person falls forward, the microcontroller 22 generates a guiding single leg (for example, a foot with a higher pressure) to advance the signal, and the driver 23 controls the balance according to the single step forward signal. The wheel 24 slides forward so that the elderly step forward to balance the center of gravity to prevent the elderly from falling; when the elderly falls backwards, the microcontroller 22 generates a signal to guide the one foot backwards, according to which the driver 23 One foot backwards step signal control balance wheel 24 slides backwards so that the elderly one foot backwards to balance the body center of gravity to prevent the elderly from falling; when the old person falls to the left, the microcontroller 22 generates a guide to the left The step signal, the driver 23 controls the balance wheel 24 to slide to the left according to the one foot to the left, so that the elderly one foot moves to the left to balance the center of gravity to prevent the elderly from falling; when the elderly falls to the right, the microcontroller 22 A pilot footing signal is generated to the right, and the driver 23 controls the balance wheel 24 to slide to the right according to the one foot to the right. The elderly person steps to the right to balance the body. Heart to prevent falls in older people.

In the present embodiment, in order to prevent the elderly from stepping on one foot, the balance of the balance of the wheel 24 affects the balance of the human body. When the driver 23 controls the balance wheel 24 to slide in the pre-fall direction of the human body to make the elderly step on one foot, the driver 23 controls the balance wheel 24 to balance the wheel 24 to spring back into the groove 13 on both sides of the sole 12, thereby making the sole plate 11 Maintaining horizontal contact with the ground ensures that the balance of the weight of the wheel 24 is not balanced due to the inertial sliding of the balance wheel 24, ensuring the effectiveness of preventing falls in the elderly.

The micro battery 25 is electrically connected to the microcontroller 22, and the micro battery 25 is used to provide working power to the fall prevention device 2. The micro battery 25 can be a rechargeable battery that can pass through a charging port. Plug directly into an external power source (such as a computer USB port or a low voltage regulator) for charging. The micro battery 25 has the characteristics of low radiation and low power consumption, and does not affect the health of the elderly.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and equivalent structural or equivalent functional changes made by the description of the present invention and the accompanying drawings may be directly or indirectly applied to other related technical fields. The same is included in the scope of patent protection of the present invention.
