Description
Technical Field
The application belongs to the technical field of weighing measurement, and particularly relates to a weighing sensor.
Background
The weighing sensor is actually a device for converting a mass signal into a measurable electric signal for output, and the common weighing sensor can only realize weighing with one measuring range specification and has a narrow measuring range.
The Chinese patent with the application number of 201480002777X discloses an electronic scale, which comprises a carrying plate, a first precision weighing assembly for supporting the carrying plate, a second precision weighing assembly for supporting the carrying plate and the first precision weighing assembly, and a force guide piece for transmitting the pressure born by the electronic scale to the second precision weighing assembly; the first precision weighing assembly comprises an elastic support; the force guide piece is provided with a force guide supporting part, and the object carrying plate is provided with a force guide press-connection part; when the object carrying plate does not carry an object, the guide force pressing part of the object carrying plate is higher than the guide force supporting part of the guide force piece; when the carrying plate carries an object, the carrying plate is stressed to press the elastic supporting piece to move downwards, and after the carrying plate is stressed to a certain degree, the guide force press-connection part of the carrying plate is pressed on the guide force supporting part of the guide force piece.
The patent application 2016100962814 discloses an adjustable double-order double-precision weighing sensor, which comprises a mounting seat, a first precision weighing sensor, a second precision weighing sensor, supporting feet, an elastic supporting piece and an adjusting mechanism for adjusting the height of the elastic supporting piece; the mounting seat is provided with a mounting plate part and a guide force supporting part for transmitting the pressure born by the mounting seat to the mounting plate part; the elastic supporting piece, the first precision weighing sensor, the mounting plate part, the second precision weighing sensor and the supporting feet are sequentially in crimping connection; the top end of the elastic supporting piece is higher than the top end of the guide supporting part in a free state, and the top end of the elastic supporting piece moves downwards under pressure. The scheme has double-order continuous measuring ranges and different precision values in each order of measuring ranges.
The two technical schemes are that objects in different weight ranges are weighed through two precision weighing sensors with different measuring ranges, the two weighing sensors have the same point, when weighing measurement is carried out, as the weighing sensors with small measuring ranges are stressed at first, if the weighing sensors with large measuring ranges weigh objects with large weight, the weighing sensors with small measuring ranges are damaged by large impact in a short time, and therefore, springs are arranged as supporting pieces. When the article with larger weight is weighed, the spring can play the effect of buffering protection on the weighing sensor with small measuring range. However, although the springs can play a corresponding role in protection, the measurement accuracy of the weighing sensor with a small measuring range is affected, because the weighing sensor with a small measuring range senses the weight through the springs. When bearing gravity, the spring can be compressed or stretched to a certain extent besides transmitting part of gravity to the weighing sensor with a small measuring range below, so that a reaction force is generated, and part of gravity acts on the spring rather than being completely transmitted to the weighing sensor with a small measuring range below; in the process of generating larger deformation of the spring, energy loss can be caused due to factors such as friction, air resistance, damping of the material and the like. These energy losses can cause the spring to not fully transfer all of the gravity or external force to the underlying small scale load cell: safety and reliability considerations are also taken into account during the design and manufacture of the spring. In order to avoid excessive deformation or damage of the springs, a certain safety margin is usually provided in the design, thereby reducing the possibility of complete weight transfer.
In summary, the springs are used as the supporting members, so that the protection effect can be achieved on the weighing sensor with a small measuring range, but the measurement accuracy of the weighing sensor with a small measuring range can be greatly affected when the weighing sensor is used for measuring objects with a light weight range.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
Example 1
As shown in fig. 1-4, a weighing sensor comprises a base 1, a first precision weighing sensor 2 is arranged on the base 1, a fixing part is arranged at the bottom of a fixed end of the first precision weighing sensor 2, the bottom of the fixing part is fixed on the base 1, the fixing part is used for lifting the first precision weighing sensor 2, a corresponding space is reserved between the lower part of a free end of the first precision weighing sensor 2 and the base 1 so as to facilitate weighing deformation, a second precision weighing sensor 3 is arranged above the free end of the first precision weighing sensor 2, and the lower part of the fixed end of the second precision weighing sensor 3 is fixedly connected with the upper part of the free end of the first precision weighing sensor 2.
The first precision weighing sensor 2 and the second precision weighing sensor 3 in this embodiment are parallel beam weighing sensors, one end of each parallel beam weighing sensor is a fixed end, the other end of each parallel beam weighing sensor is a free end, the free ends carry out load, and load articles drive the sensors to deform, so that the weight of the articles is sensed, the weighing effect is achieved, the specific structure and principle of the parallel beam weighing sensors are not repeated, the left ends of the two weighing sensors are the fixed ends, and the right ends of the two weighing sensors are the free ends, as shown in fig. 4. The first precision load cell 2 in this embodiment is a large number of load cells for measuring heavy objects, the measured weight range being approximately 1-100kg, and the second precision load cell 3 is a small-scale load cell, the measured weight range being approximately 10-1000g.
The free end of second precision weighing sensor 3 is connected with first connecting piece 4, first connecting piece 4 is connected with conducting part 5, conducting part 5 is kept away from the one end top of first connecting piece 4 and is connected with second connecting piece 6, the top of second connecting piece 6 is connected with third connecting piece 7, third connecting piece 7 has vertical section 28 and horizontal section 29 to constitute, be equipped with carrier part 8 on the third connecting piece 7, carrier part 8, the free end of first precision weighing sensor 2 and the central point of the stiff end of second precision weighing sensor 3 are all on same axis, conducting part 5 includes first conducting plate 9 and the second conducting plate 10 that set up from top to bottom, the centre of first conducting plate 9 and second conducting plate 10 upwards respectively with the downwarping form oval buffering space 11.
With reference to fig. 4, a carrying plate 18 is preferably connected to the top of the carrying portion 8, and the carrying plate 18 has a larger area, so that more articles can be placed. When the load board 18 weighs the lighter weight article, the weight of the article is firstly transferred to the third connecting piece 7 through the load board 18 and the load carrying part 8, the third connecting piece 7 descends together with the load carrying part 8 and the load carrying board 18 and simultaneously transfers the weight to the second connecting piece 6, the second connecting piece 6 transfers the weight to the third connecting piece 7 through the conducting part 5, and the third connecting piece 7 transfers the weight to the free end of the second precision weighing sensor 3. Since the conductive part 5 is composed of the first conductive plate 9, the second conductive plate 10 and the second conductive plate 10, the weight deformation amount is smaller in the gravity transmission process, especially, the weight loss of the article weight transmitted to the free end of the second precision weighing sensor 3 is less compared with that of a spring, and the measurement precision of the second precision weighing sensor 3 is improved.
When the article with larger weight is weighed, the heights of the bearing plate 18, the bearing part 8 and the third connecting piece 7 can be quickly reduced until the bottom of the horizontal section 29 of the third connecting piece 7 is propped against the fixed end of the second precision weighing sensor 3, at the moment, the weight is directly transferred to the free end of the first precision weighing sensor 2 through the fixed end of the second precision weighing sensor 3, and the weight of the article with larger weight is measured by the first precision weighing sensor 2. The rapid lowering of the height of the third connecting piece 7 is heavy and a large downward impact force is transmitted to the second connecting piece 6, which is transmitted to the first connecting piece 4 and the second precision load cell 3 through the conducting part 5, and the impact force may cause the second precision load cell 3 to be damaged, and for this reason, the middle parts of the first conducting plate 9 and the second conducting plate 10 are respectively bent upward and downward to form an elliptical buffer space 11, and the elliptical buffer space 11 forms an elliptical structure between the two conducting plates. The advantage of this construction is that when the left side of the conducting part 5 is suddenly impacted, it will create a dispersed force distribution between the two plates due to the oval special geometry, by which the energy will be transferred and spread inside the structure, resulting in a better dispersion of the impact forces. In this way, the stress peak in the local area is reduced, so that the impact force to the second precision load cell 3 is reduced, and the second precision load cell 3 is protected. At the same time, the conductive part 5 will have a certain deformation in practice, so as to absorb the impact force and play a certain role in buffering, but the buffering effect is limited, and the impact force is reduced mainly by means of dispersion force. The advantage of this way of absorbing the force by dispersing the force compared to the way of deforming is that if the impact force is greater the more pronounced the force dispersing effect is, whereas the smaller the impact force is the worse the force dispersing effect is or even the effect of dispersing the force is difficult to achieve. This is in agreement with the object of the solution according to the application. When weighing lighter weight article, because the impact force is less, the effect of strength dispersion can be ignored almost, and the weight of article can be complete the transmission for second precision weighing sensor 3, promotes the measurement accuracy of second precision weighing sensor 3. When weighing lighter weight article, because the impact force is great, the strength dispersion effect is comparatively obvious, and the less the impact force that transmits to second precision weighing sensor 3, the better the protection effect to second precision weighing sensor 3. The protection effect of the springs adopted in the traditional technology is fixed when the weight of the articles exceeds a certain weight, namely the impact force is larger and larger, so that the protection effect is limited.
In this embodiment, referring to fig. 2, the first connecting piece 4 is located below the second precision weighing sensor 3, the first connecting piece 4 includes a first upper connecting plate 12 and a first lower connecting plate 13, the first upper connecting plate 12 and the first lower connecting plate 13 are connected in sequence from top to bottom, two sides of the first lower connecting plate 13 are connecting ends, the second connecting piece 6 includes a U-shaped plate 14 with a downward opening, the U-shaped plate 14 is located above the first precision weighing sensor 2, the width of the opening of the U-shaped plate 14 is greater than the width of the first precision weighing sensor 2, a lifting space is reserved between the top of the U-shaped plate 14 and the upper side of the first precision weighing sensor 2, the second connecting piece 6 is convenient to lift, two sides of the U-shaped plate 14 are connected with a second connecting plate 15, one end of the conducting part 5 is connected with the second connecting plate 15, and the other end of the conducting part 5 is connected with the connecting end on the first lower connecting plate 13.

Through the structure and the position cooperation of second connecting piece 6 and third connecting piece 7 for conduction portion 5 is located the side of second precision weighing sensor 3, compares the position of second precision weighing sensor 3 top in traditional spring locating, very big reduction whole weighing sensor's height dimension. And the traditional spring design makes the high range of spring be fit with second precision weighing sensor 3, if the high of spring is too high, the measurement accuracy of second precision weighing sensor 3 is lower, if the high of spring is too low, deformation is difficult to carry out again, absorbs sufficient impact force, plays corresponding protection effect.
