Description

Technical Field

[0001] The utility model relates to the field of electronic products, in particular to an electronic scale bearing mechanism and an electronic scale assembly. Background Art

[0002] Electronic scales are a type of weighing instrument. Scales are tools that use Hooke's law or the principle of lever balance to measure the mass of an object. According to the structural principle, they can be divided into three categories: mechanical scales, electronic scales, and electromechanical combined scales. Electronic scales are mainly composed of a load-bearing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system, a sensor), and a value indicating system (such as a dial, an electronic display instrument). Electronic scales have a wide range of applications, such as the catering scales currently used in the catering industry.

[0003] The inventors have found that in order to meet the strength and rigidity requirements, the load-bearing mechanism composed of the load-bearing frame and the base is usually made of steel frame or molded, which results in a thicker scale body, heavier weight and higher cost; in addition, since the scale body is thicker, it is usually necessary to configure a specific dining table, or even customize a dining table with recessed positions to reduce its thickness to meet the use requirements, which increases the cost of use. Utility Model Content

[0004] The utility model aims to provide an electronic scale bearing mechanism and an electronic scale assembly, which can reduce thickness, reduce weight, reduce processing and manufacturing costs, and reduce use costs.

[0005] The embodiment of the utility model is achieved as follows:

[0007] A carrier, a sensor and a base, wherein the base includes a bottom plate and a pad that are connected, and at least part of the edge of the bottom plate protrudes from the pad; a first through hole is provided on the bottom plate, and a second through hole connected to the first through hole is provided on the pad; the sensor is clamped between the carrier and the base, and a part of the sensor corresponds to the position where the first through hole and the second through hole are connected, and the first through hole and the second through hole cooperate to provide space for the sensor to deform.

[0008] In an optional embodiment, the base plate and the backing plate are fixedly connected by fasteners.

[0009] Based on the above scheme, the connection method between the base plate and the pad is simple, the assembly time is short, and the assembly efficiency is high; and by removing the fasteners, one of the base plate and the pad can be adjusted or replaced, reducing the inspection or repair cost.

[0010] In an optional embodiment, a first fixing hole is provided on the bottom plate, a second fixing hole is provided on the backing plate, and the fastener is inserted into both the first fixing hole and the second fixing hole.

[0011] Based on the above solution, the cooperation between the first fixing hole and the second fixing hole can not only play the role of positioning the fastener, but also improve the assembly efficiency and the assembly firmness.

[0014] In an optional embodiment, an opening area of ​​the first through hole is smaller than an opening area of ​​the second through hole, so that a portion of the second through hole is blocked by the bottom plate.

[0015] Based on the above scheme, the position where the first through hole connects to the second through hole corresponds to the deformation position of the sensor, and part of the sensor also corresponds to the position of the second through hole blocked by the bottom plate. There is a certain space between the sensor and the bottom plate corresponding to the position of the second through hole. On the premise of meeting the deformation requirements of the sensor, the deformation range of the sensor can also be limited by the bottom plate to avoid excessive deformation of the sensor and affect its service life.

[0018] In an optional embodiment, the base plate has a first docking plate surface, the backing plate has a second docking plate surface, and an anti-corrosion coating is provided on one of the first docking plate surface and the second docking plate surface.

[0019] Based on the above scheme, by setting an anti-corrosion coating, the damage rate of the base plate and the pad can be slowed down, the service life of the electronic scale load-bearing mechanism can be extended, and the measurement error caused by component damage during the measurement process can be reduced, thereby improving the accuracy of the electronic scale measurement results.

[0020] In an optional embodiment, a mounting groove is provided on the support frame, the sensor is embedded in the mounting groove, and a side of the sensor close to the base protrudes out of the support frame and fits with the pad.

[0021] Based on the above scheme, by setting an installation groove, part of the sensor is embedded in the installation groove, which can reduce the distance between the load-bearing frame and the base. That is, the distance between the load-bearing frame and the base is less than the thickness of the sensor, thereby reducing the thickness of the scale body.

[0022] In an optional embodiment, one end of the sensor is fixedly connected to the support frame, and the other end of the sensor is fixedly connected to the pad and the bottom plate at the same time.

[0023] Based on the above scheme, the sensor is fixedly connected to the carrier frame and the base at the same time, the position of the sensor is stable and reliable, and the use is safe and reliable; and during use, the position of the sensor relative to the first through hole and the second through hole is not easy to change, and it is not easy to affect the accuracy of the measurement results.

[0025] The bottom shell, the weighing pan and the electronic scale load-bearing mechanism according to any one of the aforementioned embodiments, wherein the bottom shell is connected to the bottom plate, and the weighing pan is connected to the supporting frame.

[0026] The beneficial effects of the embodiments of the utility model are:

The sensor is matched with the pad and is located at a position where the strength of the base is relatively high. The base can effectively support the sensor and meet the requirements for the normal operation of the sensor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the prior art, the load-bearing structure of the electronic scale includes an upper frame, a sensor 200 and a lower frame. The upper frame and the lower frame are both formed by welding pipes such as steel pipes to form a frame structure. The pipes have internal spaces, which increase the size, resulting in large thickness of the upper frame and the lower frame, and increasing the thickness of the scale body. The scale body is large in size and weight, inconvenient to use, and has many consumables and high costs.

[0043] In view of this, the designer provides an electronic scale load-bearing mechanism with small thickness, light weight, few consumables and low cost.

[0044] Please combine Figure 1 and Figure 2 In this embodiment, the load-bearing mechanism of the electronic scale includes a carrier frame 100, a sensor 200 and a base 300, the base 300 includes a bottom plate 310 and a pad 320 connected to each other, at least part of the edge of the bottom plate 310 protrudes from the pad 320; a first through hole 311 is provided on the bottom plate 310, and a second through hole 321 connected to the first through hole 311 is provided on the pad 320; the sensor 200 is clamped between the carrier frame 100 and the base 300, and a part of the sensor 200 corresponds to the position where the first through hole 311 and the second through hole 321 are connected, and the first through hole 311 and the second through hole 321 cooperate to provide space for the deformation of the sensor 200.

[0045] Based on the above, the working mode of the electronic scale load-bearing mechanism provided in this embodiment is as follows:

[0046] The weight of the object is transmitted to the sensor 200 through the load-bearing frame, and the sensor 200 is supported by the base 300, and a part of the sensor 200 corresponds to the first through hole 311 and the second through hole 321. The sensor 200 can deform adaptively under the action of gravity, thereby realizing the measurement of weight. It should be understood that the working principle of the load-bearing mechanism of the electronic scale is the same as the existing known technology, and in order to avoid repeated description, it is not described in detail in this embodiment.

[0047] It should be understood that the load-bearing mechanism of the electronic scale in this embodiment is achieved by setting the base 300 as a structure in which the bottom plate 310 and the pad 320 cooperate, and the area of ​​the pad 320 is smaller than the area of ​​the bottom plate 310, that is, the pad 320 is convexly arranged on the bottom plate 310 and does not completely cover the bottom plate 310, the pad 320 consumables are less than the bottom plate 310, and the processing cost is low. At the same time, the strength of the position where the bottom plate 310 and the pad 320 overlap is high, that is, the thickness of some areas of the bottom plate 310 is increased, and the strength is increased. The sensor 200 cooperates with the pad 320 and is located at a position with higher strength of the base 300. The base 300 can effectively support the sensor 200 and meet the requirements for the normal operation of the sensor 200. At the same time, the base 300 is a plate structure, which is thinner than the steel frame structure formed by welding pipe fittings, and can reduce the thickness of the scale body, and the scale body is small in size and easy to use.

[0048] The following embodiments illustrate the details of the electronic scale load-bearing mechanism provided in the present application by way of examples.

[0049] Please combine Figure 1-Figure 3 In this embodiment, the electronic scale load-bearing mechanism includes a carrier 100, a sensor 200 and a base 300, and the sensor 200 is clamped between the carrier 100 and the base 300. The carrier 100 and one end of the sensor 200 are fixedly connected, and the base 300 and the other end of the sensor 200 are fixedly connected. The carrier 100 can transfer the weight of the object to the sensor 200, and the sensor 200 is deformed to perform gravity weighing.

[0050] Optionally, the support frame 100 is configured as a frame structure, and the support frame 100 includes two cross bars 110, two vertical bars 120, and a connecting plate 130. The two cross bars 110 are arranged in parallel and spaced apart, and the two vertical bars 120 are arranged in parallel and spaced apart, and the two cross bars 110 are located between the two vertical bars 120, and both ends of each cross bar 110 are fixedly connected to the two vertical bars 120. The connecting plate 130 is fixed between the two cross bars 110, and the two cross bars 110 and the two vertical bars 120 define a mounting groove 140, and the connecting plate 130 is the bottom wall of the mounting groove 140. The sensor 200 is embedded in the mounting groove 140, and the side of the sensor 200 is in contact with the connecting plate 130, and screws or bolts are arranged on the connecting plate 130, and the sensor 200 is fixedly connected to the connecting plate 130 by the screws or bolts. Due to the design of the mounting groove 140 , part of the sensor 200 is embedded in the mounting groove 140 , and the dimension between the support frame 100 and the base 300 can be smaller than the dimension of the sensor 200 , thereby shortening the distance between the support frame 100 and the base 300 .

[0051] It should be understood that after the sensor 200 is embedded in the installation groove 140, the side of the sensor 200 that is away from the connecting plate 130 protrudes out of the notch of the installation groove 140. In this way, the side of the sensor 200 that is away from the connecting plate 130 can be attached to and fixedly connected to the base 300, so that the sensor 200 can transmit the external force exerted on the supporting frame 100 to the base 300, and there will be no direct contact between the supporting frame 100 and the base 300, which will cause interference and the sensor 200 will not be able to deform under the force.

[0052] Please combine Figure 2 and Figure 3 In this embodiment, optionally, the base 300 includes a bottom plate 310 and a pad 320. Both the bottom plate 310 and the pad 320 can be set as rectangular plates. The two can be directly cut and made of metal plates such as steel plates, etc., with a simple manufacturing process and low cost. At the same time, a first through hole 311 is set in the middle position of the bottom plate 310, and the first through hole 311 is a rectangular hole. A second through hole 321 is set in the middle position of the pad 320, and the second through hole 321 is a rectangular hole. The opening area of ​​the first through hole 311 is smaller than the opening area of ​​the second through hole 321. When the pad 320 is installed on a plate surface of the bottom plate 310, the two are roughly parallel and attached together, and the edges of the pad 320 are spaced from the edges of the bottom plate 310. While the strength of the local position of the bottom plate 310 is increased, it can further reduce consumables, reduce weight, and reduce costs. At the same time, the first through hole 311 is connected to a portion of the second through hole 321, and the rest of the second through hole 321 is blocked by the bottom plate 310. When the sensor 200 is fixed to the backing plate 320 by screws or bolts, the position of the sensor 200 connected to the connecting plate 130 corresponds to the position where the first through hole 311 is connected to the second through hole 321, and the sensor 200 can be deformed normally at this position, thereby performing weight weighing. Since the position of the sensor 200 also corresponds to the position of the second through hole 321 blocked by the bottom plate 310, the sensor 200 can be restricted by the bottom plate 310 when deformed, thereby avoiding the situation where the sensor 200 is damaged due to excessive deformation, thereby extending the service life of the sensor 200.

[0053] In one embodiment, the base plate 310 and the backing plate 320 can be fixedly connected by a fastener 330. The fastener 330 can be a bolt or a screw. For example, a plurality of first fixing holes 312 are provided on the base plate 310, and a plurality of second fixing holes 322 are provided on the backing plate 320. The plurality of first fixing holes 312 are arranged around the first through hole 311, and the plurality of second fixing holes 322 are arranged at the second through hole 321. The number of the first fixing holes 312 is equal to the number of the second fixing holes 322 and they are connected one by one. The number of fasteners 330 is equal to the number of the first fixing holes 312, and a fastener 330 is inserted into the paired first fixing hole 312 and the second fixing hole 322, and the base plate 310 and the backing plate 320 are fixedly connected by the fastener 330. The connection method between the base plate 310 and the backing plate 320 is simple and reliable, and is easy to disassemble and assemble.

[0054] In another embodiment, the bottom plate 310 and the backing plate 320 may be fixed by welding, and the connection method is simple, reliable and firm.

[0055] Further, the bottom plate 310 has a first docking plate surface, the backing plate 320 has a second docking plate surface, and an anti-corrosion coating is provided on one of the first docking plate surface and the second docking plate surface. For example, the anti-corrosion coating can be provided on both the first docking plate surface and the second docking plate surface to enhance the anti-corrosion capability and extend the service life.

[0056] The load-bearing mechanism of the electronic scale provided in this embodiment has a base 300 which is a laminated plate structure with increased local strength. The base 300 has a small thickness, high strength, few consumables, and a light weight. While meeting the requirements of bearing strength, it can reduce manufacturing costs.

[0057] Please combine Figure 4 and Figure 5 This embodiment further provides an electronic scale assembly, including a bottom shell 400, a weighing pan 500, a foot 600 and the electronic scale load-bearing mechanism of the above embodiment, wherein the bottom shell 400 is connected to the bottom plate 310, and the weighing pan 500 is connected to the carrier 100. The foot 600 penetrates the bottom shell 400 and is fixedly connected to the bottom plate 310 of the base 300. The number of the foot 600 can be four, and the four foot 600 cooperate to play a role of stable support.

[0058] It should be noted that the inner bottom wall of the bottom shell 400 can be provided with reinforcing ribs, and the number of the reinforcing ribs can be multiple and cross-arranged. Part of the bottom plate 310 is supported by the reinforcing ribs to improve the strength of the bottom plate 310, and the bottom plate 310 is not easily deformed.

[0059] The electronic scale assembly provided in this embodiment has small thickness, light weight and low cost.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
