Description
Technical Field

Background
The load cell is a portable measuring instrument for measuring various forces or loads, also called a load cell, and is widely used in industries such as electric, packaging, automobile industry, food processing, and the like.
The commonly used force measuring instruments at present comprise strain type force measuring instruments, spring force measuring instruments and other instruments. The strain type force measuring instrument realizes force measurement based on a resistance strain principle, and a full-bridge circuit is formed by a high-grade foil type strain gauge stuck on a sensor elastomer. When the load is applied, the sensor elastic body deforms, and the strain gauge correspondingly senses the strain, so that the bridge is unbalanced, and an electric signal proportional to the applied force is output. The spring force measuring instrument is based on the principle that the stress of the spring is in direct proportion to the elastic deformation.
However, the current spring force measuring instrument has a small measuring range due to the limitation of the self elastic modulus, and the part of the strain force measuring instrument is an operator arm due to the stressed supporting point during use, so that the slightly heavier object cannot be measured. In addition, the force measuring instrument only displays the force during the force measuring process, cannot fully display the actual parameters of the measured product, has poor referenceability and is easy to generate errors due to the influence of environmental parameters.
Friction nano-power generation technology is an emerging power generation technology in recent years, and the principle is that two materials with different triboelectric sequences are rubbed (contacted) to generate electrostatic charges with different polarities on the surfaces of the materials, and when the contacted surfaces are separated, corresponding induced electrostatic charges are induced on respective metal electrodes to generate potential differences. The device has the advantages of simple structure, low manufacturing cost and high conversion efficiency, can effectively convert low-frequency low-amplitude mechanical energy into electric energy to supply power for small electronic equipment, can also measure related physical parameters by utilizing potential difference signals output by the device, and has wide application prospect and development potential.

Detailed Description
The embodiment of the invention provides a dynamometer, a dynamometer method, dynamometer equipment and a dynamometer system based on friction nano power generation, which are used for solving the technical problems of limited measuring range, poor referenceability and easiness in error generation of the conventional dynamometer.
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a dynamometer based on friction nano power generation.
FIG. 1 shows a block diagram of a friction nano power generation based dynamometer according to an embodiment of the present invention; fig. 2 shows a schematic diagram of the lamination of the layers in the dynamometer body provided by the embodiment of the invention.
Referring to fig. 1 and 2, the friction nano power generation-based dynamometer provided by the invention comprises a dynamometer body 1, wherein the dynamometer body 1 comprises a datum layer 11, an intermediate layer 12 and a friction layer 13 with a grid-shaped structure, which are arranged in a stacked manner; the reference layer 11 and the friction layer 13 are both made of Yi Shidian sub-material, and the intermediate layer 12 is made of readily available electronic material.
In the embodiment of the invention, the force measurement is realized mainly by using a friction nano power generation technology, and the technology is based on a Maxwell displacement current principle, combines the comprehensive effects of friction electrification and electrostatic induction, and can efficiently convert low-frequency mechanical energy which is difficult to collect by a traditional electromagnetic generator into electric energy (voltage signals). When the force is measured specifically, the same force is applied along the grid direction of the grid-shaped structure of the friction layer 13 and along the direction perpendicular to the grid direction, because the force meter body 1 is arranged by each layer, the whole is thinner, the force applied by the reference layer 11 is considered to be the same as the force applied by the friction layer 13, the friction effect generated by the reference layer 11 and the middle layer 12 is obviously different from the friction effect generated by the friction layer 13 and the middle layer 12, and the output voltage signals are also obviously different, therefore, the magnitude of the force can be measured by measuring the magnitude of the voltage signals which are output by friction of the reference layer 11 and the middle layer 12, and U12 is not influenced by the direction of the force; conversely, the magnitude of the voltage signal frictionally output by the friction layer 13 and the intermediate layer 12 is affected by the direction of the force. Therefore, the applied force can be measured by comparing and analyzing the ratio U23/U12 of the reference layer 11 and the intermediate layer 12, the ratio Δu23/Δu12 of the reference layer 13 and the intermediate layer 12, and the direction of the force obtained by comparing the ratio of the two, or the ratio Δu23/Δu12 of the two, with U12 representing the voltage signal frictionally output by the reference layer 11 and the intermediate layer 12, and Δu12 representing the variation of the voltage signal frictionally output by the reference layer 11 and the intermediate layer 12 in a preset time period, and Δu23 representing the variation of the voltage signal frictionally output by the friction layer 13 and the intermediate layer 12 in the preset time period.
The above embodiments of the present invention have at least the following unexpected benefits:
(1) Based on maxwell displacement current principle, combined with friction electrification and static induction, the friction nano power generation technology is utilized to realize force measurement, the magnitude of force is measured according to the magnitude of voltage signals which are output by friction of the reference layer 11 and the middle layer 12 of the force measuring instrument body 1 (because the magnitude of the voltage signals which are output by friction of the reference layer 11 and the middle layer 12 is irrelevant to the direction of force), and the direction of force is determined by comparing and analyzing the ratio of the magnitude of the voltage signals which are output by friction of the reference layer 11 and the middle layer 12 to the magnitude of the voltage signals which are output by friction of the friction layer 13 and the middle layer 12 or the ratio of the variation of the two, so that the measured comparison value is a relative value and is more stable and reliable;
(2) The change of the environmental parameter has the same effect on the reference layer 11 and the friction layer 13, and the measured result of the invention is not affected by environmental parameters such as temperature, humidity, pressure, etc. (the environmental parameters are generally independent of direction, and the force is a vector related to direction);
(3) The invention has the advantages of simple and novel working principle, stable working performance, convenient maintenance, high range precision grade, no limitation of the measured object, low manufacturing cost, high conversion efficiency, wide application field and the like.
In one manner that can be achieved, the Yi Shidian sub-material is an active metal material. As one embodiment, the active metal material includes at least one of lithium, sodium, potassium, beryllium, calcium, magnesium, cesium, and barium.
In one manner that can be achieved, the readily available electronic material is a non-metallic material.
As an embodiment, the nonmetallic material may be polytetrafluoroethylene, which has the characteristic of easily available electrons and has good corrosion resistance.
The friction layer 13 may have different types of grating structures. In one possible implementation, the grating structure is a right trapezoid grating structure, a comb-shaped grating structure or a fishbone-shaped grating structure.
As a specific embodiment, the staircase-shaped grating structure is shown in fig. 3, the comb-shaped grating structure is shown in fig. 4, and the fishbone-shaped grating structure is shown in fig. 5.
When different grating structures are used, the friction effect generated by the friction layer 13 under the action of the same force in different directions is different, so that the output voltage signals are different in strength. Therefore, according to the requirement of the output voltage signal strength in actual use, a corresponding grid structure can be arranged on the friction layer 13.
In one possible way, the load cell is based on a single electrode mode.
In one embodiment, the reference layer 11, the intermediate layer 12, and the friction layer 13 are each sheet-shaped.
The invention also provides a force measuring method based on friction nano power generation, which is applied to the force measuring instrument based on friction nano power generation according to any embodiment.

step S1 of acquiring a first voltage signal and a second voltage signal when the load cell is applied with the same force in the grid direction of the grid-like structure of the friction layer 13 and in the direction perpendicular to the grid direction; the first voltage signal is a voltage signal which is frictionally output by the reference layer 11 and the intermediate layer 12, and the second voltage signal is a voltage signal which is frictionally output by the friction layer 13 and the intermediate layer 12;
step S2, determining the magnitude of the applied force based on the magnitude of the first voltage signal;
and step S3, determining the direction of the applied force based on the ratio of the second voltage signal to the first voltage signal or the ratio of the variation of the second voltage signal to the variation of the first voltage signal.
In the embodiment of the invention, by utilizing the friction nano power generation principle, the same force is acted along the grid direction and the direction perpendicular to the grid direction, so that the generated friction effect is obviously different, the voltage signal U12 which is caused to be output by friction between the reference layer 11 and the middle layer 12 and the voltage signal U23 which is caused to be output by friction between the friction layer 13 and the middle layer 12 are obviously different, the magnitude of the force can be measured by measuring the magnitude of the U12 (because the magnitude of the voltage signal of the reference layer 11 is irrelevant to the direction of the force), and the direction of the force can be obtained according to the ratio U23/U12 of the two or the ratio DeltaU 23/DeltaU 12 of the variation of the two, and the force measuring method is simple and convenient.
