[0007] The technical solution according to an embodiment of the present utility models is clearly and completely described with reference to the accompanying drawings. Example

[0008] As in Fig. As shown, one embodiment of the present utility models comprises a multifunctional support bar for fall prevention for elderly people, consisting of the following components: Bar component 1;

[0009] The main control module 2, which is attached to the walking stick module 1;

[0010] The setting sensor module 3 is electrically connected to the main control module 2 and serves to monitor the setting of the rod component 1.

[0011] The distance sensor module 4 is electrically connected to the main control module 2 and is used to detect obstacles in the foreground.

[0012] as well as the wireless location communication module 5, which is electrically connected to the main control module 2 and serves to collect location data and to transmit data.

[0013] As in Fig. As shown, in some embodiments the rod component 1 comprises a rod body 11 and a handle 12 attached to the upper end of the rod body 11.

[0014] The walking stick module 1 consists of the main shaft 11 and a handle 12 attached to the upper end, forming the basic mechanical support and gripping structure of the walking stick. This construction provides a stable and reliable support body capable of bearing part of the user's body weight, while simultaneously offering a clear physical and spatial foundation for the assembly of all subsequent functional modules. This results in a compact and ergonomic overall structure.

[0015] As in Fig. In some embodiments, the main control module 2 and the module for the setting and alignment sensor 3 are integrated inside the handle 12; the top of the handle 12 is equipped with a cover 15.

[0016] The main control module 2 and the module for the setting and orientation sensor 3 are integrated inside the handle 12 and covered by the removable cover 15. The cover 15 is connected to the handle 12 by means of a removable connection – for example, a clamp connection or a screw connection.

[0017] The central electronic components are located directly in the user's hand area, simplifying wiring, cooling, and maintenance. The removable cover 15 allows for easy assembly, repair, or replacement of internal components such as the battery 6, thus increasing maintainability and extending the product's lifespan.

[0018] As in Fig. As shown, the distance sensor module 4 in some embodiments comprises a control board 41 and an integrated ultrasonic sensor 42, which is arranged on this control board 41. The upper side wall of the main rod 11 has a mounting surface 14 on which the control board 41 is attached, and the module is also surrounded by a protective housing 16.

[0019] The measuring sensor module 4 consists of the control board 41 and the integrated ultrasonic sensor 42, which are mounted together on the mounting surface 14 of the upper side wall of the main shaft 11 of the walking stick and enclosed by a protective housing 16. The ultrasonic sensor 42 is positioned in front of the side wall so that its beam is directed in the direction of walking, enabling real-time detection of obstacles in the foreground. The protective housing 16 serves to protect against collisions and dust, as well as to secure the sensor, ensuring that the ultrasonic sensor 42 functions reliably even under complex conditions.

[0020] As in Fig. As shown, in some embodiments a sound window 17 is provided on the protective housing 16 along the detection direction of the ultrasonic sensor 42, through which one end of the ultrasonic sensor 42 is passed and which is provided with a metal mesh 43.

[0021] The protective casing 16 includes a sound window 17 along the detection direction of the ultrasonic sensor 42. The sensor end passes through this window and is connected to the metal mesh housing 43. The sound window 17 serves as a channel for transmitting and receiving ultrasonic signals. The metal mesh housing 43 allows sound waves to pass through while simultaneously preventing foreign objects, dust, or water from coming into direct contact with the sensor surface, thus protecting the measurement function without impairing it.

[0022] How Fig. As shown, in some embodiments the setting sensor module 3 includes a gyroscope sensor. Using data from the setting sensor module 3 and an integrated algorithm, the main control module 2 detects when the user falls and, upon detection of a fall, triggers the wireless location communication module 5 to send an alert with location information.

[0023] The setting sensor module 3 uses a gyroscope sensor. The main control module 2 captures the setting data output by the sensor in real time, executes built-in algorithms to detect movement patterns indicative of a fall, and, upon detection, triggers the wireless location communication module 5 to send an alert and location information. This enables active fall detection with automatic alerting. If elderly people unexpectedly fall and are unable to get help themselves, an alert with location data is immediately sent to a predefined contact to extend rescue time and increase safety.

[0024] As in Fig. As shown, the wireless location communication module 5 in some embodiments is at least one of the following modules: the GPS location module, the Beidou location module or the cellular module integrated into the main control module 2.

[0025] The wireless location communication module 5 (GPS, Beidou, or cellular module) is integrated on the circuit board of the main control module 2. This hardware integration reduces the number of external connections and isolated modules, lowers overall power consumption and system size, increases reliability, and enables real-time acquisition and remote transmission of location data to support functions such as tracking, locating, and electronic fencing.

[0026] How Fig. As shown, in some embodiments, a non-slip spring bar 13 is detachably mounted at the lower end of the main shaft 11. This spring bar is attached to the base of the main shaft 11 in a movable and removable manner and increases friction and stability when it comes into contact with the ground, thus coping with different ground conditions. The detachability allows the user to replace worn spring bars or to select spring bars made of different materials depending on the usage environment, thereby extending the overall service life of the walking stick 1.

[0027] As in Fig. As shown, one particular embodiment also includes a battery 6 for powering the individual electrical modules. The battery 6 is integrated into the handle 12. The main control module 2 has an integrated charging port 21, the connection of which is left exposed at the end of the handle 12, thus allowing the connection of a charger.

[0028] A battery 6 is integrated into the handle 12 as a power source. The main control module 2 has an integrated charging port 21, the connection of which extends to the outer end of the handle 12. The battery 6 is built into the handle 12, which places the center of gravity at the top and makes it more stable to hold. The integrated charging port 21 on the main control board simplifies the internal wiring. The connection on the handle 12 allows the user to conveniently connect and disconnect the charging cell – thus simplifying the charging process and improving the overall appearance.

[0029] As in Fig. In some embodiments, screw holes 18 are provided on the mounting surface 14, while corresponding through-openings 19 are provided on the protective cover 16.

[0030] A screw hole 18 is provided on the mounting surface 14, and a passage 19 is provided at the corresponding location in the protective cover 16. The protective cover 16 is secured by inserting a screwdriver through the passage 19 and tightening it in the screw hole 18. The threaded connection ensures a reliable and tight connection between the protective cover 16 and the mounting surface 14, prevents displacement or loosening of the sensor due to vibrations or collisions, and thus guarantees the stability of the detection direction and the accuracy of the distance measurement of the ultrasonic sensor 42.

[0031] The distance measurement module 4 uses an HC-SR04 (42) ultrasonic sensor, whose trigger signal, return signal, power, and ground connections are each connected to the corresponding control interfaces of the main control module 2. The main control module 2 is based on an ESP32 series system-on-chip (SoC), which provides integrated WLAN and Bluetooth functionality as its core processor and enables positioning and data transmission for the wireless positioning communication module 5 via its wireless communication capabilities. Simultaneously, it processes data from module 3 of the setting sensor, controls the ultrasonic sensor 42 for distance measurement, and coordinates the interaction of all modules, thus achieving a high degree of hardware integration and unified system management.

[0032] Building upon the multifunctional fall prevention support for the elderly, the health monitoring and intelligent interaction functions can be further expanded. For example, a health data monitoring module—such as a heart rate or blood pressure sensor—can be integrated into the support component 1 to capture the user's physiological parameters in real time. This data is transmitted via the wireless location communication module 5 to the associated smartphone app, allowing the user or caregiver to remotely monitor the user's health status and be immediately notified of any deviations. Furthermore, a voice control module can be added, enabling users to retrieve their current location, initiate a one-touch emergency call, or access other simple functions via voice command—making human-machine interaction significantly more intuitive and user-friendly.Accordingly, the smartphone app's functionality can also be expanded through service upgrades – for example, by integrating features such as querying historical movement paths, setting up electronic safety fences with exceedance warnings, remote monitoring of device power levels, and automatic fault monitoring and reporting. This creates a complete safety monitoring system for the elderly, encompassing everything from hardware to software services.

[0033] To ensure the accuracy and reliability of its core functions, the perception and decision-making system of the multifunctional fall protection glove for the elderly can be continuously optimized. In the fall detection module, the accuracy of fall detection can be improved by updating the posture detection algorithm, integrating data from multi-axis sensors, and introducing more advanced pattern recognition models. This effectively reduces false alarms caused by movements such as bending or sitting. In the ultrasonic interference detection system, the sensor transmitter and receiver circuitry, as well as the signal processing algorithms, can be optimized to expand the effective detection range and increase sensitivity and interference resistance under varying lighting conditions and with different materials.This ensures stable system performance in both complex indoor environments and changing outdoor conditions. Furthermore, the accuracy of the positioning and the reliability of the connection of the positioning and communication module can be improved in signal-obfuscating environments – for example, between high-rise buildings or under trees. This is achieved, for instance, by combining multimodal positioning signals with inertial navigation data, thus guaranteeing reliable positioning and continuous monitoring throughout the entire service life.

[0034] In summary, the combination of the distance sensor module 4 with ultrasonic sensor 42, which is attached to the side wall of the main pole 11 via the mounting surface 14, the protective housing 16, the acoustic window 17, and the metal mesh guard 43 enables reliable detection of obstacles in the foreground while simultaneously providing excellent protection. The tilt sensor module 3, in conjunction with the algorithm of the main control module 2, automatically detects falls and sends an alarm message with precise location information via the wireless positioning communication module 5 – significantly improving emergency response capabilities. Since the wireless positioning communication module 5 is directly integrated into the main control module 2, cable connections are reduced and system reliability is increased. The removable, non-slip support legs 13 enhance adaptability and maintainability.The integrated charging port 21 on the handle 12 ensures easy and convenient charging. The overall structure provides the individual functional modules with a compact and ergonomically designed support base, thus improving the safety, intelligence, and user-friendliness of the pole.
