[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Example 1, combined with the attached Figure 1-3 , an upper limb functional rehabilitation stick, comprising a stick body 1:

[0026] An electronic palm gripper 2 is fixed on the upper part of the stick body 1, and an inclination monitoring alarm device 3 is provided on the stick body 1;

[0027] An upper limit sleeve 4 and a lower limit sleeve 5 are provided on the upper part of the rod body 1. The upper limit sleeve 4 is sleeved on the rod body 1 and is located above the electronic palm gripper 2. The lower limit sleeve 5 is sleeved on the rod body 1 and is located below the electronic palm gripper 2. One side of the upper limit sleeve 4 is threadedly connected to an upper limit bolt 6, and one side of the lower limit sleeve 5 is threadedly connected to a lower limit bolt 7.

[0028] During use, the user picks up the stick 1 and firmly grasps the electronic palm gripper 2 with one hand. The display on the electronic palm gripper 2 automatically displays the current grip strength value, helping the user understand their grip strength. By continuously grasping and relaxing, the user can achieve the effect of grip training. At the same time, the stick 1 is always in a suspended state, which can also train the user's grasping ability. In addition, the tilt monitoring alarm device 3 can monitor the tilt angle of the stick 1. When the tilt angle of the stick 1 exceeds the set value, the tilt monitoring alarm device 3 will alarm and remind the user, thereby achieving upper limb training for the user and facilitating rehabilitation. According to the user's needs, the upper limit bolt 6 and lower limit bolt 7 are loosened, the upper limit sleeve 4 and lower limit sleeve 5 are adjusted, and then the upper limit bolt 6 and lower limit bolt 7 are tightened. When the user moves the wrist, the stick 1 is turned up and down. When the hand slides relative to the stick 1, the upper limit bolt 6 and lower limit bolt 7 can limit the hand and prevent the stick 1 from slipping.

[0029] In this embodiment, the rod 1 is a retractable adjustment rod. When the user's grip strength is insufficient, the rod 1 can be extended according to the user's needs. When the user uses it, the lower end of the rod 1 contacts the ground to provide support for the rod 1, without affecting the user's grip training.

[0030] In this specific embodiment, the rod body 1 uses a two-stage telescopic adjustment rod, including an outer tube 101, an inner tube 102 plugged into the outer tube 101, and a tension nut 103. The tension nut 103 is threadedly connected to the upper end of the outer tube 101. By turning the tension nut 103, the inner tube 102 and the outer tube 101 can be fixed or moved relative to each other. Loosening the tension nut 103 allows the inner tube 102 to move relative to the outer tube 101, and the extension length of the inner tube 102 relative to the outer tube 101 can be adjusted to adjust the overall length of the rod body 1. After the length is adjusted, the tension nut 103 is tightened to fix the inner tube 102 and the outer tube 101 relative to each other.

[0031] In this embodiment, the lower end of the outer tube 101 is covered with a protective sleeve 8, which is connected to the outer tube 101 by interference fit. The protective sleeve 8 can protect the lower end of the outer tube 101, wherein the protective sleeve 8 can be made of plastic or rubber.

[0032] In this embodiment, a pipe plug 9 is provided at the upper end of the inner tube 102, and a connecting ear 10 is provided at the upper end of the pipe plug 9. The pipe plug 9 and the inner tube 102 are connected by an interference fit, and the pipe plug 9 and the connecting ear 10 are integrally formed. When not in use, the upper limb functional rehabilitation rod can be hung by the connecting ear 10 for easy retrieval later. The connecting ear 10 can also be connected to an anti-drop wrist rope. When in use, the anti-drop wrist rope can be looped around the user's wrist to prevent it from accidentally falling to the ground when grasping.

[0033] In this embodiment, the tilt monitoring alarm device 3 is arranged above the upper limit sleeve 4. This design allows the tilt monitoring alarm device 3 to be located above the hand when the user grasps it, which is equivalent to the user holding the tilt monitoring alarm device 3 with their hand. The gravity is above the hand, which is more conducive to training the upper limb balance.

[0034] In this specific embodiment, the tilt monitoring and alarm device 3 includes a housing 301, a tilt sensor 302, a control processor 303, and a speaker 304. The tilt sensor 302, control processor 303, and speaker 304 are installed inside the housing 301 and are electrically connected to the rechargeable battery in the electronic palm gripper 2. The tilt sensor 302 and speaker 304 are also electrically connected to the control processor 303. A speaker hole 305 is provided on one side of the housing 301. A switch 306 is provided on the main circuit between the tilt monitoring and alarm device 3 and the electronic palm gripper 2. The switch 306 is located on the side of the housing 301. During use, when the tilt monitoring and alarm device 3 detects that the tilt angle is greater than the set value, the speaker 304 issues a voice alarm.

[0035] In this embodiment, the electronic palm gripper 2 uses the Zhongyiheng EH216 electronic counting gripper. It has a built-in high-precision sensor that automatically records single grip strength and total repetitions, displaying the data in real time on an LED screen. It supports data storage for up to 19 users, with adjustable gender and age parameters for personalized training recommendations. The strength range is adjustable from 0 to 180 kg.

[0036] In this specific embodiment, the inclination sensor 302 adopts the Witte WT9011DCL-BT50 inclination sensor, which integrates a MEMS gyroscope + accelerometer + geomagnetic field sensor with an accuracy of ±0.01° and supports the Kalman dynamic filtering algorithm, which can effectively eliminate human body jitter noise and ensure the accuracy of angle data during rehabilitation training; the control processor 303 adopts the nRF52832 Bluetooth low-power microcontroller, which uses the ARM Cortex-M4F core, has a main frequency of 64MHz, supports floating-point operations, can process inclination data in real time and run the threshold judgment algorithm, with a standby current of <1μA and an operating current of <4mA, which matches the long battery life requirements of the rehabilitation stick and provides SDK support for custom alarm logic; the speaker 304 adopts the CUIDevices CMT-8540-65-SMT ultra-thin chip buzzer with a diameter of 8.5mm, a thickness of 3.5mm, an operating voltage of 3-5V, a current of <10mA, and a sound pressure of 85dB, which is suitable for embedding in a small shell.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0038] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.
