[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0033] Further, the handle 20 is provided with a pressure detection unit 40, and the front end or the rear end of the handle 20 is provided with a switch assembly 50 for controlling the lifting of the electric telescopic rod 30. As preferred, the switch assembly 50 is arranged at the front end of the handle 20, so that the old people can use the thumb or the index finger to press and operate when holding, and in the process of adjusting, the pressure detection unit 40 cooperates with the switch assembly 50 and the microcontroller 10 and is triggered by the finger operation of the hand to realize the lifting adjustment of the electric telescopic rod 30.

[0034] In addition, in order to further improve the comfort of holding, a handle sleeve 60 is sleeved on the handle 20, and the handle sleeve 60 covers the outside of the pressure detection unit 40. It should be noted that the handle sleeve 60 needs to ensure that it does not affect the normal work of the pressure detection unit 40. The pressure detection unit 40 can be a resistance type pressure sensor or a capacitive type pressure sensor.

[0035] By skillfully arranging the switch assembly 50 on the handle 20 at a position easy for the thumb or index finger of the hand to operate, the user can conveniently adjust the height of the walking stick. When the height of the walking stick needs to be increased, the pressure detection unit 40 detects the downward pressure of the hand and feeds back a signal to the microcontroller 10 when the pressure reaches a preset threshold, and the microcontroller 10 immediately stops the motor, thereby ensuring that the walking stick can be accurately stopped at the desired height.

[0036] When the height of the walking stick needs to be decreased, the user presses the switch assembly 50 to shorten the electric telescopic rod 30, and when the height is decreased to the desired height, the user stops pressing the handle 20 downward so that the pressure detection unit 40 is triggered again, and the microcontroller 10 controls the electric telescopic rod 30 to stop shortening. Of course, the user can also continuously press the switch assembly 50 to keep the electric telescopic rod 30 lengthening and shortening, and the electric telescopic rod 30 stops working when the user releases the finger, thereby achieving the height adjustment. However, this adjustment method is not convenient for the elderly who cannot keep the finger pressed stably.

[0037] The whole height adjustment process of the present scheme is realized through the real-time detection and feedback of the pressure detection unit 40, which can greatly improve the user experience. In actual use, the user can measure the height to be adjusted according to the counter-pressure between the electric telescopic rod 30 and the arm, which is more suitable for the use of the elderly.

[0038] In the present embodiment, the pressure detection unit 40 and the switch assembly 50 are located at the upper part of the handle 20, so that the pressing position is more in line with the operation habit when the hand holds the handle 20, thereby ensuring the comfort of use.

[0039] In the present embodiment, the pressure detection unit 40 is located at the position corresponding to the palm of the handle 20, so as to increase the area of the detection region and ensure the sensitivity of the pressure detection.

[0040] In the present embodiment, the switch assembly 50 includes an increase control switch 51 and a decrease control switch 52, which are arranged in the front-rear direction or the left-right direction. Different arrangement modes can be selected according to actual needs.

[0041] The up control switch 51 and the down control switch 52 are ingeniously arranged at positions on the handle most easily operated by the old people, and the touch feeling design is unique, the soft rubber material in a convex form is adopted, the old people can easily touch the buttons only by the natural perception of the hands without deliberately searching. The up control switch 51 and the down control switch 52 are connected with the control circuit of the motor by waterproof and anti-interference wires, to ensure the stability and reliability of the signal transmission. The control circuit adopts an advanced microcontroller 10 (MCU) as the core control unit, the microcontroller 10 has strong computing power and rich interface resources. The pressure detection unit 40 selects a high-precision pressure sensor as the telescopic control signal source, and the installation position is carefully designed to accurately detect the change of the force applied by the palm of the hand to the handle.

[0042] In the embodiment, the upper end of the electric telescopic rod 30 is provided with a C-shaped bending part 301, the upper end of the C-shaped bending part 301 is connected with the front end of the handle 20, the switch assembly 50 is located on the side of the pressure detection unit 40 facing the C-shaped bending part 301, and the midpoint of the handle 20 can be translated to the axis of the electric telescopic rod 30 through the C-shaped bending part 301, to ensure that the downward pressure of the palm of the hand of the old people when using the walking stick can be vertically transmitted to the ground through the electric telescopic rod 30, and the stability of the center of gravity is ensured.

[0043] In the embodiment, the handle 20 is internally provided with a mounting cavity; the mounting cavity is internally provided with a microcontroller 10 and a battery 70 for supplying power to the microcontroller 10; the pressure detection unit 40, the switch assembly 50 and the electric telescopic rod 30 are electrically connected with the microcontroller 10; further, the rear end surface of the handle 20 is provided with a power key 80 electrically connected with the microcontroller 10, the battery 70 is a rechargeable battery 70, the handle 20 is further provided with a power indicator lamp 90 and a charging interface 100 for charging the battery 70, to facilitate the user to master the power condition and facilitate charging and switching.

[0044] In the embodiment, the electric telescopic rod 30 comprises an inner tube 301, an outer tube 302 coaxially and slidingly sleeved outside the inner tube 301, and a lead screw module 303 fixedly arranged in the outer tube 302; the lower end of a lead screw shaft 3031 of the lead screw module 303 extends into the inner tube 301 and is rotationally connected with the inner tube 301 through a lead screw sleeve 3032. The lead screw module 303 is electrically connected with the microcontroller 10, and the outer diameter of the inner tube 301 and the inner diameter of the outer tube 302 are designed with accurate tolerances, so that the inner tube 301 can stably and smoothly slide up and down inside the outer tube 302, which not only ensures the flexibility of telescoping, but also maintains the stability of the overall structure.

[0045] The motor 3033 of the screw module 303 is a high-performance, low-power micro DC motor with a reduction mechanism, which has the advantages of small size, large torque and strong stability, and can operate efficiently in the limited space inside the walking stick. The motor 3033 is connected with the screw shaft 3031 through a precision shaft coupling 110 and a reducer 160, ensuring zero clearance and high reliability during power transmission. The screw shaft 3031 adopts a precision screw transmission mode to realize power-off self-locking and stable torque transmission.

[0046] The pitch and thread accuracy of the screw are strictly controlled to ensure that the inner tube 301 can move up and down accurately and smoothly under the drive of the screw, thereby realizing accurate adjustment of the length of the walking stick.

[0047] In this embodiment, the lower end of the electric telescopic rod 30 is provided with a buffer 120, which bears the important responsibility of supporting the walking stick, the weight of the human body and the mutual resistance and buffering of the force between the human body and the ground during walking.

[0048] Specifically, the buffer 120 includes a longitudinally arranged support rod 121 and an elastic member 122 for providing elastic return force to the support rod 121. The elastic member 122 is specifically a spring, but can also be a good elastic rubber pad or gas spring. The upper end of the support rod 121 coaxially extends into the inner tube 301 and is axially slidingly connected therewith. The lower end of the support rod 121 is fixedly provided with a guide sleeve 130, and the lower end of the guide sleeve 130 is completely wrapped outside the lower end of the support rod. The outer wall of the guide sleeve 130 is coaxially slidingly fitted with the inner wall of the inner tube 301. Further, a step 140 is arranged at the lower end of the guide sleeve 130 to stop the inner tube 301 from descending too far. A limiting portion 150 is arranged on the inner wall of the inner tube 301 above the guide sleeve 130, and an elastic return member is arranged between the limiting portion 150 and the guide sleeve 130 to function as a spring. Moreover, the limiting portion 150 is arranged in a circular ring shape, which can also be used to mount and guide the support rod 121 for the support rod 121 to slide up and down. In order to prevent the support rod 121 from falling off, a limiting protrusion 1210 with a diameter larger than the inner diameter of the limiting portion is arranged at the upper end of the support rod 121 above the limiting portion 150.

[0049] In order to further enhance the stability and comfort of the walking stick, the end portion of the guide sleeve 130, i.e. the portion contacting the ground, is made of special anti-skid rubber material. The surface of the rubber material has a unique texture design, such as dense diamond protrusions or wave-shaped lines, which can generate strong friction on various ground materials, effectively preventing the walking stick from slipping during use.

[0050] The lower end of the whole inner tube 301 is designed with a buffer structure, which can effectively alleviate the impact force of the ground on the human knee joint when walking with the walking stick, protect the damaged knee joint and improve the use experience of the walking stick. At the same time, a soft and good anti-skid handle sleeve 60 is tightly wrapped on the handle, and the surface of the handle sleeve 60 is provided with delicate granular protrusions, which can not only increase the friction between the hands and the handle to prevent the walking stick from accidentally falling, but also provide additional comfortable touch for the hands of the old people.
