[0031] like Figure 1 and Figure 2 As shown, the operation, measurement and analysis handle provided by the embodiment of the present invention includes a housing 100, a force measuring shaft 200 and a detection device 300. The detection device 300 includes a circuit component 310 and a sensor component 320 connected to the circuit component 310. The force measuring shaft 200, the sensor component 320 and the circuit component 310 are all arranged in the housing 100, and the sensor component 320 is connected to the force measuring shaft 200.
[0032] The operation, measurement and analysis handle of the embodiment of the present invention can be applied to a variety of operations or movement forms completed by the operation, measurement and analysis handle. A force measuring shaft 200, a circuit component 310 and a sensor component 320 are arranged in the housing 100. The force measuring shaft 200 can be connected to various tools. Through the connection between the sensor component 320 and the force measuring shaft 200, the measurement of multi-dimensional force, acceleration, posture and other signals is completed, and then used to monitor the multi-dimensional force, acceleration and posture of the operator's hand operation on the operation, measurement and analysis handle. Through the connection between the sensor component 320 and the circuit component 310, the collected data is sent to the peripheral device through wireless transmission, and then digitized, and then the operation characteristics are analyzed in a multi-dimensional and multi-modal manner, so as to standardize the operation characteristics, shorten the learning cycle, or evaluate the quality of the operation.
[0033] According to an embodiment provided by the present invention, the sensor assembly 320 includes a radial force sensor and an axial force sensor. The radial force sensor is arranged on the outer wall of the force measuring shaft 200, and the axial force sensor is arranged on the end of the force measuring shaft 200 and is coaxially connected to the force measuring shaft 200. In this embodiment, the operation applied by the operator to the operation measurement and analysis handle is converted into a multi-dimensional force applied to the force measuring shaft 200. The sensor assembly 320 mainly detects the radial force and axial force applied to the force measuring shaft 200, that is, the radial force sensor and the axial force sensor are respectively connected to the force measuring shaft 200. When the force measuring shaft 200 is subjected to radial force, the radial force sensor can measure the deformation of the force measuring shaft 200 caused by the radial force, and then transmit the deformation signal to other peripherals of the detection device 300. When the force measuring shaft 200 is subjected to axial force, the axial force sensor is coaxially connected to the force measuring shaft 200, and the axial force sensor can measure the magnitude of the axial force applied to the force measuring shaft 200, and then transmit the signal to other peripherals of the detection device 300.
[0034] In this embodiment, the sensing component 320 may also adopt a six-dimensional force sensor, which is connected to the force measuring shaft 200 . The six-dimensional force sensor can measure the radial force and axial force exerted on the force measuring shaft 200 .
[0035] According to an embodiment provided by the present invention, the radial force sensor includes a plurality of stress sheets 321 , each stress sheet 321 extends along the axial direction of the force measuring shaft 200 , and the plurality of stress sheets 321 are evenly arranged around the axial direction of the force measuring shaft 200 , and the stress sheets 321 are connected to the circuit assembly 310 . In this embodiment, the radial force sensor uses a plurality of stress sheets 321, which are resistance strain sheets. The radial force signal of the operating measurement and analysis handle is measured by the plurality of stress sheets 321. Each stress sheet 321 is in the shape of a long strip, and its extension direction is the axial direction of the force measuring shaft 200. The plurality of stress sheets 321 are evenly distributed around the outer wall of the force measuring shaft 200. When the front end of the force measuring shaft 200 connecting tool is subjected to radial force, the force measuring shaft 200 where the stress sheet 321 is set will deform, and at the same time drive the stress sheet 321 to undergo measurable deformation. The change in resistance generated by the deformation of the plurality of stress sheets 321 can reflect the magnitude of the radial force received by the force measuring shaft 200. The stress sheet 321 is connected to the circuit assembly 310, and sends the signal to the circuit assembly 310. The even distribution of the stress sheets 321 can fully sense the partial deformation of the force measuring shaft 200 and improve the detection accuracy.
[0036] According to an embodiment provided by the present invention, the axial force sensor includes a one-dimensional pressure sensor 322, a first mounting hole 211 is provided on the end surface of the force measuring shaft 200, one end of the one-dimensional pressure sensor 322 is inserted into the first mounting hole 211, and the other end is connected to the housing 100, and the cable of the one-dimensional pressure sensor 322 is connected to the circuit assembly 310. In this embodiment, the axial force sensor uses a one-dimensional pressure sensor 322, and the axial force signal of the operation measurement and analysis handle is measured by the one-dimensional pressure sensor 322. The axial setting direction of the one-dimensional pressure sensor 322 is the axial direction of the force measuring shaft 200, and the rear end of the force measuring shaft 200 is provided with a first mounting hole 211 along the axial direction of the force measuring shaft 200. The front end of the one-dimensional pressure sensor 322 is inserted into the first mounting hole 211 and connected to the force measuring shaft 200, and the rear end is connected to the housing 200. When the dynamometer shaft 200 is subjected to an axial force, the dynamometer shaft 200 transmits the axial force to the one-dimensional tensile pressure sensor 322 , thereby measuring a signal of the axial tensile pressure of the dynamometer shaft 200 .
[0037] like Figure 4 As shown, according to an embodiment provided by the present invention, the force measuring shaft 200 includes a connecting shaft section 210, a square shaft section 220, a mounting section 230 and an interface section 240 which are sequentially connected along the axial direction, an axial force sensor is provided on the end face of the connecting shaft section 210, a shaft sleeve 250 is sleeved on the outer side of the square shaft section 220, an outer side wall of the shaft sleeve 250 is connected to the outer shell 100, the mounting section 230 is provided with a hollow portion 231, a radial force sensor is arranged on the mounting section 230, and the interface section 240 is used to connect with an external tool. In this embodiment, a circuit component 310, a one-dimensional tensile pressure sensor 322, a connecting shaft section 210 of the force measuring shaft 200, a square shaft section 220, a mounting section 230 and an interface section 240 are sequentially arranged in the housing 100 along its axial direction, wherein the interface section 240 serves as the front end of the force measuring shaft 200, and the connecting shaft section 210 serves as the rear end of the force measuring shaft 200. The square shaft section 220 adopts a square self-lubricating shaft, and a shaft sleeve 250 fixed to the housing 100 is sleeved on the outer side of the square shaft section 220. The shaft sleeve 250 is relatively fixed, and the square shaft section 220 reciprocates axially in the square through hole in the middle of the shaft sleeve 250, thereby filtering the multi-dimensional force generated by the interface section 240 into axial tensile pressure. The axial force signal is detected by the one-dimensional pull pressure sensor 322. The sleeve 250 is made of a self-lubricating material with relatively high rigidity, which can constrain the radial deflection and axial torsion of the force measuring shaft 200 in the square shaft segment 220. When the friction between the square shaft segment 220 and the sleeve 250 is small enough, it can be considered that the one-dimensional pull pressure sensor 322 detects the axial component of the resultant force acting on the force measuring shaft 200.
[0038] The cross-sectional area of the mounting section 230 is smaller than that of the square shaft section 220. Four hollow portions 231 extending along the axial direction of the force measuring shaft 200 are provided at the square shaft section 220. The stress sheet 321 can be correspondingly glued to the surface of the mounting section 230 beside the hollow portion 231 by special glue. Since the mounting section 230 has a small cross-sectional area, the deformation is large, so that the stress sheet 321 thereon undergoes a measurable deformation, and the change in the resistance value of the four stress sheets 321 can reflect the magnitude of the radial force. At the same time, the mounting section 230 forms a hollow structure through the hollow portion 231, and the deformation under force is large, which is easy to measure.
[0039] In this embodiment, the interface section 240 can be installed with various tools, such as rackets, drumsticks, liposuction needles, etc., through quick connection, threading, matching and other methods, so as to achieve high scalability of the operation, measurement and analysis handle application, and can be equipped with multiple tools to meet different task requirements.
[0040] According to an embodiment provided by the present invention, the mounting section 230 includes a plurality of mounting plates 232, each of which extends along the axial direction of the force measuring shaft 200, and the plurality of mounting plates 232 are arranged to form a hollow shaft section coaxial with the square shaft section 220, and each of the mounting plates 232 is provided with notches on both sides, and the two notches between two adjacent mounting plates 232 constitute a hollow portion 231. In this embodiment, the mounting section 230 is composed of four mounting plates 232, one end of the mounting plate 232 is connected to the end face of the square shaft section 220, and the other end is connected to the end face of the interface section 240. The four mounting plates 232 are arranged to form a square hollow shaft section. A notch is arranged on the side of the mounting plate 232, and two adjacent notches form a hollow portion 231, that is, a stress sheet 321 is sandwiched between two adjacent mounting plates 232. Due to the small cross-sectional area of the mounting plate 232, the radial force of the force measuring shaft 200 will cause the mounting plate 232 to deform greatly, so that the stress sheet 321 thereon will undergo a measurable deformation, and the magnitude of the radial force can be reflected by the change in the resistance value of the four stress sheets 321. The setting of the mounting plate 232 can respond to the deformation caused by the radial force to the greatest extent, so that the stress sheet 321 can be accurately detected.
[0041] According to an embodiment provided by the present invention, the circuit assembly 310 includes a circuit board 311 and a force sensing module 312 connected to the circuit board 311, and the radial force sensor and the axial force sensor are both connected to the force sensing module 312.

[0042] According to an embodiment provided by the present invention, the sensor component 320 also includes a motion sensor module 313, and the motion sensor module 313 is disposed on the circuit board 311. In this embodiment, the sensor component 320 can also be used to measure motion signals such as operation acceleration and posture. The motion sensor module 313 is welded on the circuit board 311 and is used to measure the acceleration and posture motion signals of the operation measurement and analysis handle in three-dimensional space, so as to convert the collected electrical signals of the acceleration and motion signals into digital signals for subsequent processing and digitization by the detection device 300.
[0043] In this embodiment, the motion sensing module 313 may use a 9-axis motion sensor and related components, and the 9-axis motion sensor includes a 3-axis accelerometer, a 3-axis gyroscope and a 3-axis magnetometer.
