[0034] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0035] In the present disclosure, unless otherwise clearly stipulated and limited, terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements.

[0036] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In the description of this specification, the description of the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily have to be directed to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples without contradicting each other.

[0037] From the above background technology, it can be seen that fall detection for users (especially elderly users) is very important. In the related technology, there are also a variety of wearable fall detection devices, which usually use different technical principles to detect whether the user falls. Among them, the technologies used by common fall detection devices include:

[0038] Millimeter wave radar technology: This technology can detect whether the user has fallen by transmitting and receiving millimeter wave signals. If a fall occurs, the reflection and reception of the millimeter wave signal will change, thus triggering the fall detection function. The advantage of this device is that it can achieve passive monitoring without any user operation. However, the detection accuracy of this device may be affected by environmental factors, such as the presence of interference, which may affect the detection accuracy.

[0039] Camera technology: This technology can detect whether a user has fallen through image recognition and artificial intelligence algorithms. When a user wears a device equipped with a camera, the device can capture images of the user in real time and analyze them. If a fall occurs, the device can trigger the fall detection function by identifying the user's posture and movements. The advantage of this device is that it can achieve high detection accuracy while also enabling other functions such as monitoring the user's activities and behavior. However, this device may infringe on the user's privacy and requires high computing power and data storage capabilities.

[0040] Moreover, the detection device corresponding to the method of detecting whether the user has fallen provided by the related technology is usually a hand-worn or head-worn device. For example, using devices such as watches and smart bracelets, such devices are usually worn on the user's hands and have other functions (for example, payment, calls and other functions); therefore, such devices consume a lot of power, and some users may not like to wear such devices. At the same time, when the user is performing hand activities, the posture changes are usually large. In order to avoid false alarms as much as possible, some of the fall detection accuracy may be sacrificed, resulting in low accuracy of fall detection. That is, the wearing method in the related technology is easy to make some users uncomfortable to wear, and it is also easy to miss the problem of carrying (so that it cannot play a detection role); moreover, because it is worn on the user's hand, in order to avoid false alarms, the fall detection accuracy is not high.

[0041] Based on this, the present disclosure provides a fall detection device, which is used to be installed on a foot-worn device. Users usually wear the foot-worn device when walking, exercising, sitting, etc., and the foot-worn device usually does not undergo large posture changes during the user's walking, exercising, sitting, etc., so that only a more economical posture sensor can be used to determine whether the user is in a fall state; and because the fall detection device includes a posture sensor, a control chip and a power supply, the number of components included is relatively small, thereby reducing the overall volume of the fall detection device and facilitating the installation of the fall detection device on the foot-worn device.

[0042] Furthermore, users only need to wear the foot wearable device on their feet to detect whether the user has fallen. The position change of the foot during normal activities is usually small, so it can more accurately detect whether the user is in a state of falling, making the missed alarm rate and false alarm rate extremely low. At the same time, since the overall size of the fall detection device is small, it can be installed on different types of shoes, which can achieve full coverage of indoor and outdoor safety protection, and allow users to use it without feeling uncomfortable wearing.

[0043] At the same time, since there is no need to collect the user's image information, user privacy can be protected and there is no concern about use; fewer components are used and the connection relationship is simple, which makes the product cost low; and the processing process of posture information can also be performed in the cloud, which makes the overall power consumption of the fall detection device smaller, and the battery life of the fall detection device is higher, so there is no need for frequent charging.

[0044] See also Figure 1 The present disclosure provides a fall detection device 10, which is used to be installed on a foot wearable device. The fall detection device 10 may include:

[0045] Device body 110, attitude sensor 120, control chip 130 and power supply 140;

[0046] The posture sensor 120, the control chip 130 and the power supply 140 are all disposed in the device body 110;

[0047] The power supply 140 is connected to the control chip 130 and the posture sensor 120, and the power supply 140 is used to provide electrical energy;

[0048] The control chip 130 is connected to the posture sensor 120 , and the control chip 130 is used to process the posture information detected by the posture sensor 120 .

[0049] It should be noted that the power supply 140 can provide electrical energy for any component in the fall detection device 10 (including but not limited to: the posture sensor 120, the control chip 130, etc.).

[0050] Here, since the fall detection device 10 is installed on the foot wearable device, and the foot wearable device is equipment that the user wears when walking, installing the fall detection device 10 on the foot wearable device can better detect whether the user falls, and at the same time, can avoid false detection as much as possible.

[0051] As an example, the posture sensor 120 , the control chip 130 and the power supply 140 are all disposed in the device body 110 , so that the device body 110 can protect the posture sensor 120 , the control chip 130 and the power supply 140 .

[0052] In some possible ways, the posture sensor 120, the control chip 130 and the power supply 140 can be stacked in the device body 110, so that the size of the fall detection device 10 can be small, and it is convenient to install the fall detection device 10 on the foot wearable device. For example, the radius of the device body 110 can be only 1 cm.

[0053] As an example, the posture information is determined by the posture sensor 120. Compared with the related art that uses camera technology and millimeter wave radar technology to determine the posture information, the posture sensor 120 is cheaper and more stable than the camera and millimeter wave radar. Therefore, the fall detection device 10 uses the posture sensor 120 to determine the posture information, which can also save the manufacturing cost of the fall detection device 10.

[0054] As an example, by using the posture information determined by the posture sensor 120 and identifying and processing the posture information, it can be determined whether the user is in a falling state. Specifically, the posture sensor 120 detects the posture information of the fall detection device 10, and since the fall detection device 10 is installed on the foot wear device, the posture information of the foot wear device can be determined based on the posture mapping relationship between the fall detection device 10 and the posture sensor 120. The user wears the foot wear device, and at this time, the user's posture information can be determined based on the posture information of the foot wear device, thereby determining whether the user is in a falling state.

[0055] It should be understood that when the control chip 130 processes the posture information collected by the posture sensor 120, it can determine whether the user is in a falling state based on the above concept. Of course, how the control chip 130 processes the posture information is not limited here. For example, the control chip 130 only performs preliminary preprocessing on the posture information, and then transmits the posture information to the cloud, so that the cloud can identify and process the posture information, thereby determining whether the user is in a falling state.

[0056] It should be noted that the specific model of the power supply can be limited according to actual conditions. For example, the model of the power supply can include but is not limited to: CR2016, CR2032, CR1620, LR44, LR41, LIR2032, LIR2050 and other button batteries and 601818, 602020 and other soft-pack polymer lithium batteries.

[0057] That is, the power source of the present disclosure can be a rechargeable battery or a common dry cell. The specific selection of the power source can be reasonably set according to the actual situation.

[0058] It can be seen that the fall detection device in the present disclosure can be used to be installed on a foot-worn device, and the user usually wears the foot-worn device during walking, exercising, sitting, etc., and the foot-worn device usually does not undergo large posture changes during the user's walking, exercising, sitting, etc., so that only a more economical posture sensor can be used to determine whether the user is in a fall state; and because the fall detection device includes a posture sensor, a control chip and a power supply, the number of components included is relatively small, thereby reducing the overall volume of the fall detection device and facilitating the installation of the fall detection device on the foot-worn device.

[0059] As examples, the gesture sensor may include, but is not limited to, a three-axis sensor, a six-axis sensor, and a nine-axis sensor.

[0060] In some implementations, the gesture sensor can include a six-axis sensor.

[0061] It should be understood that a six-axis sensor generally refers to a sensor device that integrates a three-axis gyroscope and a three-axis accelerometer. This sensor can measure the angular velocity and acceleration of an object in three axes, thereby determining the object's posture information.

[0062] Specifically: The working principle of the six-axis attitude sensor is based on the working principle of the gyroscope and accelerometer; the gyroscope uses the gyro effect to measure the angular velocity of an object, while the accelerometer uses the acceleration of an object under the action of gravity to measure the tilt angle of the object; by integrating these two sensors together, the six-axis attitude sensor can measure the angular velocity and acceleration of an object at the same time, and obtain the attitude information of the object through calculation.

[0063] That is, the posture information of the fall detection device can be accurately determined using the six-axis posture sensor.

[0064] In some embodiments, the above-mentioned fall detection device may further include: an information transmission module;

[0065] The control chip and the power supply are both connected to the above-mentioned information transmission module, and the information transmission module is used to transmit the specified information to the predefined device according to the instructions of the control chip.

[0066] As an example, the specified information may include, but is not limited to: alarm information, posture information.

[0067] For example, the control chip can directly process posture information and determine whether the user is in a falling state. When it is detected that the user is in a falling state, the alarm information can be directly transmitted to the predefined device so that users related to the user can receive timely reminders and know the user's situation.

[0068] In some implementations, the predefined device may include, but is not limited to, a communication device corresponding to the user's guardian, a specific medical communication device, etc. The alarm information may be provided in the form of a voice call, a text message, an APP notification, etc.

[0069] For another example, the designated information may be posture information. In this case, the posture information detected by the posture sensor may be transmitted to the predefined device, so that the predefined device determines whether the user is in a falling state according to the posture information. This method can reduce the amount of calculation of the fall detection device, thereby making the endurance of the fall detection device stronger.

[0070] As an example, the transmission mode corresponding to the information transmission module includes but is not limited to local wireless mode (such as Bluetooth, LoRa (Long Range Radio), Zigbee) or NB-IoT (Narrow Band Internet of Things), 4G (fourth generation network communication technology), 5G (fifth generation network communication technology), etc. Of course, the specific information transmission mode can be limited according to the actual situation.

[0071] In some possible implementations, the above-mentioned fall detection device may further include: a positioning module, and the positioning module may be used to locate the fall detection device.

[0072] Of course, the specific positioning method of the positioning module can be limited according to actual conditions. For example, GPS (Global Positioning System) positioning, Beidou positioning, base station positioning, WiFi positioning and the like can be used for positioning.

[0073] In some embodiments, the fall detection device may further include: a storage device. Of course, the specific model and specification of the storage device may be limited according to actual conditions. For example, it may include but is not limited to an embedded memory, an ePOP memory, an nMCP memory, etc.

[0074] As an example, Figure 1 The information transmission module, the positioning module and the storage device can be integrated on the control chip 130.

[0075] In some implementations, the fall detection device can also transmit posture information and pace information to the cloud, so that the cloud can evaluate the user's health status based on the posture information big data and the pace information big data.

[0076] In some embodiments, you can continue to refer to Figure 2 , the fall detection device may further include: an electromagnetic receiver 150;

[0077] The electromagnetic receiver 150, the posture sensor 120, the control chip 130 and the power supply 140 may be stacked in the device body 110;

[0078] The electromagnetic receiver 150 is connected to the power supply 140 , and is used to convert the electromagnetic signal into electric current, and input the electric current into the power supply 140 for storage.

[0079] As an example, the setting of the electromagnetic receiver 150 can realize wireless charging, so there is no need to replace the power supply 140 or charge the power supply 140 with a wired interface. The sealing of the fall detection device 10 can be better, which can also improve the applicability of the fall detection device 10.

[0080] Furthermore, this method can also facilitate the installation of the fall detection device on the bottom of the foot wearable device. When the fall detection device needs to be charged, it is only necessary to place the foot wearable device on the corresponding charging base.

[0081] It should be understood that the principle of wireless charging is to use electromagnetic induction technology to transfer electrical energy to the fall detection device through a magnetic field, thereby realizing the charging of the fall detection device. Specifically, the wireless charging device mainly consists of two parts: a transmitter and a receiver. The transmitter generates a high-frequency alternating magnetic field through a built-in coil, and the built-in coil of the receiver receives the magnetic field energy and converts it into electrical energy, thereby realizing the charging of the fall detection device.

[0082] In some embodiments, the fall detection device may further include: a metal charging contact point,

[0083] The metal charging contact point is arranged on the surface of the device body; the metal charging contact point is connected to the power source.

[0084] It should be understood that setting a metal charging contact point can realize contact charging. The principle of contact charging is: the spring contact pin on the charger and the metal charging contact point on the fall detection device are in close contact to realize the transmission of power. This charging method has the advantages of being simple and direct. At the same time, since the contact points are directly connected, the charging efficiency is relatively high.

[0085] Of course, the specific location of the metal charging contact point can be limited according to actual conditions. For example, it can be set at the bottom of the device body.

[0086] In some embodiments, the electromagnetic receiver may be disposed at the bottom of the inner cavity of the device body, and the control chip may be disposed at the top of the inner cavity of the device body.

[0087] As an example, an electromagnetic receiver disposed at the bottom of the device body can enhance the charging effect when charging the fall detection device.

[0088] As an example, the control chip can also be provided with function keys to enable the fall detection device to implement corresponding functions (e.g., switch, reset, call for help, etc.), and by placing the control chip at the top of the inner cavity of the device body, the user can more easily operate the set function keys, thereby making it easier for the user to set the functions of the fall detection device, such as power on, reset, call for help, etc.

[0089] In some embodiments, the fall detection device may also include: a fixed structure adapted to the foot-worn device; the fixed structure is connected to the device body, and the fixed structure is also used to connect to the foot-worn device.

[0090] In some implementations, the fixing structure is connected to the bottom of the device body. The device body and the foot wear device can be connected together through the fixing structure.

[0091] As an example, the fixing structure may include but is not limited to: a buckle, an adhesive fixing structure, a clamping fixing structure, etc. Of course, in a specific implementation, the form of the fixing structure may be limited according to actual conditions.

[0092] In some embodiments, the shape of the device body may include a cylindrical shape.

[0093] As an example, the cylindrical setting can make it very convenient to install the fall detection device.

[0094] In some embodiments, a first stable structure is provided on the cylindrical surface of the device body, and the first stable structure is adapted to the second stable structure, wherein the second stable structure is used to be provided on the foot wearable device.

[0095] For example, the fall detection device is installed on the bottom of the foot wear device. Taking the foot wear device as a shoe as an example, the fall detection device can be installed on the sole, and a first stabilizing structure is provided on the cylindrical surface, which can be matched with a second stabilizing structure in a circular depression provided on the sole. In this way, the fall detection device and the foot wear device can be more closely combined. Figure 1 To explain, Figure 1 The outer surface of the device body 110 is provided with vertical edges, so that the fall detection device can be better fixed to the foot wearable device.

[0096] In order to facilitate understanding of the installation relationship between the fall detection device and the foot wear device disclosed in the present invention, it can be combined with Figures 3A-3E To explain, Figures 3A-3E It can be understood as a schematic diagram of the installation position relationship between the fall detection device and the foot wear device. Figures 3A-3E It can be seen that the fall detection device can be installed on the sole or on the upper. In this way, the fall detection device can be installed on both outdoor shoes and home shoes. In this way, no matter the user is out or at home, the fall detection device can be used to detect whether the user has fallen.

[0097] It can be seen that the fall detection device in the present disclosure, because it is used to be installed on a foot wearable device, can reduce the probability of false detection of the fall detection device, and can use a more affordable six-axis sensor to determine the posture information. The various components can also be placed in a stacked manner to reduce the size of the fall detection device, so that the fall detection device can be more conveniently installed on the foot wearable device.

[0098] At the same time, since the connection position between the fall detection device and the foot wearable device is relatively flexible, the fall detection device can be installed on different types of shoes, which means that users can use the fall detection device to detect falls whether they are at home or out.

[0099] In some embodiments, you can continue to refer to Figure 4 , Figure 4 The present disclosure also provides a foot wear device 20, which may include: a wearable body 200 and the above-mentioned fall detection device 10; and the fall detection device 10 is connected to the wearable body 200.

[0100] In some implementations, the wearable body may include a sole, an upper, and an insole;

[0101] Any one of the above-mentioned sole, the above-mentioned upper and the insole is connected to the above-mentioned fall detection device.

[0102] It should be understood that when the fall detection device is set on the insole, the various elements in the fall detection device can be arranged horizontally, so as to reduce the vertical volume of the fall detection device, so as to better set the fall detection device on the insole.

[0103] In some implementations, the specific connection method between the fall detection device 10 and the wearable body 200 can be limited according to actual conditions. The specific connection method between the fall detection device 10 and the wearable body 200 is not limited here.

[0104] In some embodiments, the sole is connected to the fall detection device, and the sole is provided with a receiving cavity for receiving the fall detection device, and the fall detection device is arranged in the receiving cavity.

[0105] As an example, the area of ​​the sole corresponding to the center of the user's foot may be provided with a cavity for accommodating the fall detection device. In this way, when the user is walking, the squeezing force received by the fall detection device is reduced, thereby improving the durability of the fall detection device.

[0106] Of course, there are many ways to install the wearable body 200 and the fall detection device 10, and there are also many types of combined installations, for example, Figures 3A-3EIt shows that part of the installation method of the present disclosure is, of course, in a specific implementation, the specific installation method of the wearable body 200 and the fall detection device 10 can be limited according to actual conditions.

[0107] It can be seen that the method disclosed in the present invention can make the shoes produced have the fall detection device pre-installed, so that the shoes have the fall detection function. Moreover, this method can also make the combination of the fall detection device and the shoe body more secure.

[0108] Furthermore, this method can also ensure that the appearance of the shoes themselves is not changed, so that the shoes can retain their original appearance and structure while also having a fall detection function.

[0109] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0110] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction, and the present disclosure will not further explain various possible combinations.

[0111] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
