detailed description

Embodiment one

Referring to accompanying drawing 1, it is a structural schematic diagram of Embodiment 1 of the present invention.

The device of the present invention includes an elastic object 4 for applying force to the force sensor probe 21. The elastic object 4 has a one-to-one relationship between the force and its deformation, and is characterized in that the first end 11 of the top plate is hinged , the second end 12 of the top board is used to apply elastic force to the elastic object 4 , when the top board 1 is in different positions, the top board 1 exerts different forces on the elastic object 4 .

Hinged means rotatable, that is to say, the first end 11 of the top plate is rotated by the hinge shaft 3 .

The force sensor 2 is a common sensor, which converts the mechanical quantity into an electrical quantity to measure the mechanical quantity, that is to say, the force sensor 2 is a force-electric conversion device, and the force sensor 2 used is to use the force-electric conversion to work sensor. There are many kinds of force sensors 2, some of which can only display real-time measurement data, such as common electronic scales for selling vegetables; Science and technology experiment. Those skilled in the art can judge what kind of force sensor 2 to choose after reading this specification.

The part of the force sensor 2 for detecting force is called a force sensor probe 21 .

Why can the length be measured in Embodiment 1? What is its principle? How does it work for measuring length?

We know that the force sensor 2 measures the force, and we also know that elastic objects 4, such as springs, such as rubber cords, such as rubber blocks, have a one-to-one relationship between the magnitude of their force and the amount of deformation, and the amount of change in length also belongs to Deformation, the basic principle of the present invention is exactly to transform the deformation into the magnitude of force, and then transform the magnitude of force into the change in length.

After reading this specification, those skilled in the art should know that the position of the hinge shaft 3 is fixed, and the position of the force sensor 2 is also fixed. In the drawings of the specification, a common way of expressing the fixed position is used to represent the fixed position.

further:

The force sensor probe 21 and the elastic object 4 are fixedly connected. In fact, it is also possible that the force sensor probe 21 and the elastic object 4 are not fixedly connected, but only in contact. Because applying elastic force does not require a fixed connection, just contact, of course, welding is also possible. Fixed connections allow for more reliable measurements without free travel.

The elastic object 4 is fixedly connected with the second end 12 of the top plate. In fact, contact is also possible. The benefit of fixing is that the measurement is more reliable without free travel.

If the elastic object 4 is only in contact with the force sensor probe 21 and the top plate 1, then other devices are needed to control the position of the spring so as to prevent the elastic object 4 (such as the spring) from rolling off.

The elastic object 4 is a spring. Springs are good elastics 4. The spring has a large amount of deformation, and the spring can not only be stretched, but also compressed. For the force sensor 2, the force sensor probe 21 is subjected to a pulling force or a force (that is, pressure) opposite to the pulling force, and the values displayed by the force sensor 2 are different (such as +5N, -5N). The spring is also a typical elastic object 4 that satisfies Hooke's law. Such an elastic object 4 has good linearity when deformed, and the spring is preferably used as the elastic object 4 .

Preferably, the elastic object 4 is an elastic object 4 whose deformation is proportional to the elastic force it receives.

Preferably, the set spring is a spring satisfying Hooke's law.

Embodiment two

Referring to accompanying drawing 2, it is a schematic structural diagram of Embodiment 2 of the present invention.

It also includes: a base surface 5 for placing the object to be measured. The base surface 5 serves as the starting point of the length. To measure the length between two points, there must always be a starting point and an end point, and the second end 12 of the top plate is used as the end point, so the base surface 5 is used as the starting point.

Embodiment Three

Referring to accompanying drawing 2, it is a structural representation of the present invention.

It also includes: a cable 6, which is used to prevent the top plate 1 from falling. One end of the cable 6 is connected to the top plate 1, and the other end of the cable 6 is fixed.

Preferably, the dragline 6 is a rubber cord.

Utilize embodiment one, two, three, the method for measuring length or height is like this:

A length measurement method characterized by:

The measuring steps of the method include:

In the first step, the distance S between the base surface 5 and the second end 12 of the top plate is obtained,

In the second step, one end of the object to be tested is placed on the base surface 5, and the other end bears against the second end 12 of the top plate. The second end 12 of the top plate applies force to the elastic object 4, and the elastic object 4 is deformed, resulting in a deformation amount L.

The third step is to read the elastic value F of the force sensor 2,

In the fourth step, according to the one-to-one correspondence between the elastic force value F and the deformation value L, the value of L is known,

In the fifth step, the result obtained by adding L to S is the length of the object to be tested.

It should be noted that: as a measurement method, the present invention has a base surface 5, but as a product, the base surface 5 is not necessary. Because the base surface 5 can choose the ground or even the wall. Except the base surface 5, the product described in the present invention can be produced and sold independently, so the base surface 5 can be removed in the protection scope of the present invention.

It should also be noted that after reading the measurement principle described in this specification, those skilled in the art should know that: the distance S between the base surface 5 and the second end 12 of the top plate, when measuring S, the top plate 1 and the elastic object 4 should be There is no free stroke. The free stroke, that is, when the second end 12 of the top plate compresses or stretches the elastic material 4, it needs to pass through a blank area at one end, and the second end 12 of the top plate does not contact the elastic material 4 in this blank area. , which is of course unacceptable.

It should also be noted that:

According to the one-to-one correspondence between the elastic force value F and the deformation amount L, the value of L is obtained. How to know the value of L? For those skilled in the art, this is simply not a problem. Since the elastic object 4 is used, the deformation amount of the elastic object 4 is related to the elastic force received, then the relationship between the deformation amount and the elastic force should be known in advance, which can be obtained in advance by the method of experimental measurement, or by searching the data It can be calculated by the manual, and can also be calibrated directly with standard instruments. That is to say, when I see the elastic force displayed by the force sensor 2, I know the amount of deformation of the elastic object 4, and this amount of deformation can be either the amount of compression or the amount of stretching. As mentioned above, the force sensor 2 can display the magnitude of the force, and can display the pressure or the tension.

It should also be noted that:

When nothing else exerts elastic force on the top plate 1, the value displayed by the force sensor 2 may not be zero. For example, the measurement of the force sensor 2 is not cleared, such as the influence caused by the gravity of the top plate 1, such as the influence caused by the gravity of the elastic object 4, this Those skilled in the art should know that corresponding adjustments should be made during reading or data processing. Even people who sell vegetables know that electronic scales should be cleared, let alone scientific and technological workers.

We can use this device to measure the height of athletes, which is one of the physical indicators of athletes.

The method for measuring athlete's height is characterized in that:

Embodiment Four

Referring to accompanying drawing 4, it is a schematic structural diagram of Embodiment 4 of the present invention.

Also include the push rod 7 that the top plate second end 12 is provided with, the push rod 7 is arc-shaped, the radius of the arc where the push rod 7 is located is equal to the distance from the top plate second end 12 to the top plate first end 11, one end of the push rod 7 and The second end 12 of the top plate is fixedly connected, and the other end of the push rod 7 is used to apply elastic force to the elastic object 4,

Also includes a sleeve 8, the sleeve 8 is hollow, the sleeve 8 is bent into an arc, the radius of the arc where the sleeve 8 is located is equal to the radius of the arc where the push rod 7 is located, the push rod 7 extends to the hollow part of the sleeve 8, and the elastic 4 is arranged inside the sleeve 8, when the top plate 1 rotates toward the sleeve 8, the ejector rod 7 penetrates into the sleeve 8 and exerts elastic force on the elastic object 4.

Preferably, the plane where the push rod 7 is located coincides with the rotation plane of the second end 12 of the top plate. In other words: the plane defined by the push rod 7 coincides with the rotation plane of the second end 12 of the top plate. Why use the word sure? Because the push rod 7 is an arc, the arc can determine a plane.

The devices described in Embodiments 1, 2, and 3 all have a problem: read the force value from the force sensor 2 and then determine the deformation amount, and the obtained deformation amount has a large error.

Why? The reason is that the direction of the elastic force exerted by the second end 12 of the top plate is not perpendicular to the force sensor probe 21, or it cannot always be vertical because the top plate 1 is rotated. The magnitude of the force sensed by the force sensor probe 21 is usually directional, that is, the elastic force detected by the force sensor probe 21 is a pressure perpendicular to the contact surface of the probe.

So how to solve this technical problem? The technical scheme that embodiment four provides is exactly to solve this technical problem, and the technical effect that embodiment four can achieve is: when top plate 1 rotates, (of course, it is not continuous circles like a motor, but turns over a certain radian), no matter which angle it rotates to, the force felt by the force sensor probe 21 is perpendicular to the contact surface of the probe.

Anyone with a little knowledge of mechanics knows that force is a vector and can be decomposed. If the elastic force is measured, the elastic force must be perpendicular to the contact surface of the force sensor probe 21. This is basic common sense. We use a force of 10 Newtons perpendicular to the electronic scale, and the electronic scale displays 10 Newtons. If a force of 10 Newtons that is not perpendicular to the contact surface of the electronic scale acts on the electronic scale, the force displayed by the electronic scale is not 10 Newtons. Of course, the electronic scales selling vegetables on the market have already converted the readings into kilograms through internal circuits.

How does Embodiment 4 achieve such a technical effect? Please see: the process that the second end of the ejector rod 7 is close to the elastic object 4 is the process that the ejector rod 7 extends to the inside of the sleeve 8, and the radius of the arc where the ejector rod 7 is located is equal to the distance from the second end 12 of the top plate to the first end 11 of the top plate. Distance, the radius of the arc where the sleeve 8 is located is equal to the radius of the arc where the push rod 7 is located, then the push rod 7 can be stretched in and out in the sleeve 8, thereby compressing the elastic object 4, such as a spring, or using the spring as the For example, please continue to read: the spring can not only change its length along its axial direction, that is, stretch and compress, but also bend perpendicular to its axial direction. In the fourth embodiment, it can be achieved that the elastic object 4 (such as a spring) always applies an elastic force in the vertical direction to the force sensor probe 21 . In other words, the elastic object 4 is perpendicular to the force sensor probe 21 , or in other words, the force applied direction of the elastic object 4 is perpendicular to the force sensor probe 21 , which is the most basic common sense.

Those skilled in the art should know that the sleeve 8 needs to give the push rod 7 a certain stroke area, otherwise, the push rod 7 is blocked by the sleeve 8 as soon as it intends to extend into the inside of the sleeve 8 .

Those skilled in the art should know that the inside of the sleeve 8 should be as smooth as possible, and the elastic object 4 (such as a spring) should not be subjected to too much resistance along its axial direction.

Those skilled in the art should know that in order to prevent the push rod 7 from falling off from the sleeve 8, a baffle plate with an opening can be arranged on the opening of the sleeve 8 near the second end 12 of the top plate, and the top plate 1 is at the end extending into the sleeve 8 Provide a tab to prevent it from coming out of the bezel.

further:

The center of the arc where the push rod 7 is located coincides with the first end of the push rod 7 . Why is this technical feature not an essential technical feature? Because through some simple mechanical devices, it can be converted to: the center of the arc where the ejector rod 7 is located does not coincide with the first end of the ejector rod 7 . Therefore, it is not a necessary technical feature that the center of the arc where the ejector rod 7 is located coincides with the first end of the ejector rod 7 .

The center of the arc where the sleeve 8 is located coincides with the first end of the push rod 7 . It is not a necessary technical feature, for the same reason as above.

What are the benefits of base 5 movement? Answer: It can be measured dynamically, which improves the measurement efficiency. When the measuring object is on the base surface 5 and moves with the base surface 5 and passes through the second end 12 of the top plate, the height or length is detected.

From the F-t image, finding the value of the elastic force when the highest point of the object under test slides over the second end 12 of the top plate is a skill that those skilled in the art should master.

Embodiment seven

Referring to accompanying drawing 7, it is the structural representation of the present invention. Also includes slip stitch 9. The sliding pin 9 is rod-shaped, one end of the sliding pin 9 is fixedly connected to the top plate 1, and the other end of the sliding pin 9 is used to contact the object to be tested.

With the sliding needle 9, it is equivalent to extending the top plate 1 and shortening the lateral distance.

Embodiment Eight

If the base surface 5 moves at a uniform speed, and the elastic object 4 satisfies Hooke's law, then the tracing work can be completed by using the present invention. why? What is its principle?

Take accompanying drawing 7 as an example, an object, a certain surface has a certain profile, then, when the object passes through the second end 12 of the top plate (if there is a slip pin 9, it is when passing the slip pin 9), the force sensor 2 The shape of the depicted F-t image is similar to the contour passed through during contact. The similarity here does not mean that the F-t image is similar to the contour image, but that the contour image is enlarged or reduced in proportion, which is completely consistent with the F-t image, that is to say , the similarity mentioned here refers to the similarity of similar triangles. We can directly use the F-t image obtained by the force sensor 2 to represent the contour image to be measured.

The base surface 5 moving at a uniform speed means that, in the F-t image, the length ratio represented by the t-axis is equal to the length ratio of the object to be measured parallel to the surface where the base surface 5 is located. Therefore, it can be obtained that the shape of the F-t image depicted by the force sensor 2 is similar to the contour passed through during contact.

Those skilled in the art should know that the present invention cannot measure the contour of the entire circumference, and users should choose the present invention according to the situation, and cannot use any surface of any object to describe the contour.

Those skilled in the relevant art should know that: the second end 12 of the top plate (or the sliding pin 9 ) should not be stuck on the object to be tested.

Those skilled in the relevant art should know that for some objects with discontinuous curved surfaces, or objects with the second end 12 of the top plate that cannot touch all the surfaces to be measured, it is not suitable to use the present invention to describe the contour.

Certainly, if want to obtain F-t image, described force sensor 2 should select the force sensor 2 that has the function of depicting F-t image for use, if want to export the contour of depicting, that preferably force sensor 2 has image derivation function, image derivation function is not necessary , because people can use camera equipment or scanning equipment to obtain the image of the force sensor 2 screen.
