Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, the present invention provides a bite force measuring device, generally comprising a control terminal 1 and at least one bite force sensing unit 2. The biting force sensing unit 2 includes a sensing body 3 and a sensing head 4. The inductive head 4 is connected with the inductive body 3. The inductive head 4 is provided with at least one hollow 41. A pressure measuring unit 42 is provided in the hollow portion 41. When an animal bites in the hollow part 41 of the induction head 4, the pressure measurement unit 42 is pressed to generate a force signal (such as a voltage signal, a current signal, a magnetic field signal, etc.), so that the pressure measurement unit 42 measures and obtains biting force data. The control terminal 1 is connected with the occlusion force sensing unit 2 through electric signals. The control terminal 1 can receive the occlusal force data measured by the pressure measuring unit 42 and estimate the animal's occlusal force according to the occlusal force data.

Preferably, the occlusion force data comprises an occlusion force magnitude measured by the pressure measurement unit 42 and an occlusion site determined by the position of the pressure measurement unit 42. After receiving the occlusion force data measured by the pressure measurement unit 42, the control terminal 1 performs data correction based on the occlusion force and the occlusion part to obtain real occlusion force data, thereby accurately estimating the occlusion force of the animal according to the occlusion force data and solving the problem of large deviation of the occlusion force data.

Specifically, the control terminal 1 is a terminal integrated with a data processing device and a data display device. For example, the control terminal 1 may be a processor, a computer device, or the like. The data processing equipment comprises a singlechip, an A/D converter, a low-pass filter and a charge amplifier; the data display device includes a display screen and the like. In a specific embodiment, upon receiving the occlusion force data (i.e. the force signal generated by the pressure measurement unit 42 being pressed, such as a voltage signal, a current signal, a magnetic field signal, etc.), the weak voltage signal output by the piezoelectric sensor sheet is amplified by the charge amplifier and converted into a voltage signal that can be measured by the apparatus. The low-pass filter is used for eliminating external electromagnetic wave interference and outputting a clean voltage signal after being filtered by the filter circuit; the clean voltage signal is output to an a/D converter, and the analog electric signal is converted into a digital signal that can be recognized by the control terminal 1. The single chip microcomputer is used for converting the input digital signals through a formula to obtain the occlusal force data, transmitting the occlusal force data to the data display equipment and displaying the occlusal force data on the display screen. It is to be understood that the control terminal 1 is not limited to the above-mentioned devices, and may be a data processing system or device known to those skilled in the art, which aims to process and analyze the occlusion force data measured by the pressure measuring unit 42 to evaluate the occlusion force size.

The biting force sensing unit 2 includes a sensing body 3 and a sensing head 4. As shown in fig. 2-4, the inductive head 4 is provided with at least one hollow portion 41. In an alternative embodiment, the inductive head 4 is cylindrical to better accommodate the biting forces of the animal. The hollow portion 41 is located on the circumferential side surface of the inductive head 4. A pressure measuring unit 42 is provided in each hollow portion 41.

Alternatively, the pressure measurement unit 42 employs a piezoelectric pressure sensor. The piezoelectric pressure sensor converts a measured pressure into an electric signal by using the piezoelectric effect of a piezoelectric material. The piezoelectric element made of piezoelectric material has linear relation between the charge amount generated by pressure and the acting force, and the measured pressure can be known by measuring the charge amount. The piezoelectric pressure sensor may be a diaphragm type or a piston type pressure sensor. As shown in fig. 4, the diaphragm type piezoelectric pressure sensor is taken as an example and mainly comprises a body, a diaphragm and a piezoelectric element, when the diaphragm type piezoelectric pressure sensor is arranged in the hollow portion 41, the body of the diaphragm type piezoelectric pressure sensor is positioned at the bottom of the hollow portion 41, and the diaphragm is positioned at the notch of the hollow portion 41 and basically covers the notch of the hollow portion 41. By providing a plurality of hollow portions 41 and a plurality of pressure measurement cells 42 on the circumferential side surface of the sensor head 4, the diaphragm of the diaphragm type piezoelectric pressure sensor can cover most of the area of the circumferential side surface of the sensor head 4. When the animal bite force is measured, the teeth of the animal are bitten on the diaphragm of the diaphragm type piezoelectric pressure sensor, the diaphragm is pressed down under stress and acts on the piezoelectric element of the diaphragm type piezoelectric pressure sensor, and then an electric signal can be generated, so that the bite force data can be measured. And then the control terminal 1 is used for data processing and analysis, so that the size of the animal bite force can be evaluated.

The number of the hollow portion 41 may be one or more. When the number of the hollow portion 41 is one, the surface of the pressure measuring unit 42 may be designed in an arc shape in conformity with the circumferential side surface of the inductive head 4 so that it can have a large area and be more easily bitten by an animal, thereby facilitating measurement. As shown in fig. 2 and 3, when the number of the hollow portions 41 is plural, several hollow portions 41 are distributed in a staggered manner, so that the hollow portions 41 occupy the area of the circumferential side surface of the inductive head 4 (cylinder) as much as possible, so that the inductive head is easily bitten by an animal, thereby facilitating measurement. Alternatively, the ratio of the area of the hollow portion 41 to the area of the peripheral side surface of the induction head 4 (cylindrical body) ranges from 0.5 to 0.9.

In a preferred embodiment, as shown in fig. 5, a cover 43 is provided on a side of the pressure measuring unit 42 away from the inductive head 4. A gap is formed between the cover body 43 and the surface of the inductive head 4, the cover body 43 covers the gap of the hollow part 41, and the area of the cover body 43 is not smaller than that of the hollow part 41. Through the setting of lid 43, can play the guard action to pressure measurement unit 42 to can increase pressure measurement unit 42's atress measuring area, make when using, the animal bites more easily, thereby conveniently measures. Alternatively, the cover 43 may be in the shape of an arc-shaped piece that conforms to the peripheral side surface of the inductive head 4, and the peripheries of adjacent covers 43 are fitted to each other, so that a large area of exposure of the peripheral side surface of the inductive head 4 is avoided.

The invention provides an occlusal force measuring device, wherein a plurality of hollow parts 41 are arranged on an induction head 4, and a pressure measuring unit 42 is arranged in each hollow part 41, thereby realizing the measurement of the occlusal force of animals. When the animal is in a small size, the mouth and teeth are small, and the biting force is weak, and when the animal is measured, the small size animal can bite only a small number of pressure measuring units 42 (for example, 1-4 pressure measuring units), and then the biting force of the small size animal can be evaluated through data processing and analysis by the control terminal 1. When the animal is large in size, the mouth and teeth of the animal are large, and the occlusal force is also strong, and when the animal is measured, the large-size animal can bite a large number of pressure measurement units 42 (for example, 4-10), and then the control terminal 1 processes and analyzes data measured by the large number of pressure measurement units 42, so that the occlusal force of the large-size animal can be evaluated. By using a large number of pressure measurement units 42 to perform distributed stress and measurement on the occlusal force of a large animal, the measurement accuracy can be improved, and the problem that the stress range of a single pressure measurement unit 42 is small can be avoided.

In one particular embodiment, as shown in fig. 2-5, the interior of the inductive head 4 is provided with a hollow bore 44. The hollow hole 44 is used for penetrating a wire rod connecting the pressure measuring unit 42 with the sensing body 3 and/or the control terminal 1. Through hiding the wire rod inside inductive head 4, avoid the wire rod to expose the fragile problem that leads to. It should be understood that the electrical signal connection between the sensing body 3 and the control terminal 1 may be a wired connection through a wire, or a wireless connection through a wireless communication module disposed in the sensing body 3.

In a specific embodiment, the outer surface of the sensor head 4 is further provided with a food inducing adhesive layer (not shown in the figure) for inducing animals to bite the sensor head 4. Preferably, the food calling adhesive layer covers the outer surface of the induction head 4, so that an animal can be conveniently induced to strongly bite the induction head 4, and the result of measuring the animal bite force is more accurate. The food calling glue layer is movably mounted on the outer surface of the induction head 4 through the food calling glue fixing mechanism, so that the relative position of the food calling glue layer and the induction head 4 can be conveniently adjusted, and the food calling glue layer is replaced after the food calling glue layer is bitten, damaged and failed for many times.

In a preferred embodiment, the food calling adhesive layer is disposed along the length direction of the inductive head 4, and the food calling adhesive fixing mechanism includes a thread fixing structure or a buckle structure. The food calling adhesive layer is arranged on the outer surface of the induction head 4 through a bolt or a buckle structure. Illustratively, the food calling adhesive layer is provided with an opening matched with the screw, the induction head 4 is provided with at least two screw holes matched with the screw along the axial direction, and the food calling adhesive layer is arranged on the induction head 4 through the matching of the screw, the opening and the screw holes.

In a particular embodiment, the conditioning structure 5 and the electrical storage device 6 are provided inside the inductive body 3. The adjusting structure 5 is connected to the inductive head 4 for adjusting the telescopic length of the inductive head 4. The adjusting structure 5 may be a mechanical structure known to those skilled in the art, such as a sliding track structure, a screw structure, an elastic member structure, and the like. The sensing body is provided with an interface (not shown in the figure). The interface is used to connect a power supply and/or control terminal 1 to supply electric power to the electric storage device 6.
