[0036] Logistics and transportation technology mainly includes two categories: transportation facilities and transportation operations. Transportation hard technology mainly includes transportation infrastructure, such as the improvement of infrastructure such as roads, railways, shipping, and transport vehicles. Transportation soft technology includes management methods, logistics technology, and logistics personnel literacy. Express delivery is the main work object of logistics and transportation. In the express delivery collection link, it usually includes inspection, packaging, weighing, measurement, printing, labeling, code scanning, etc., among which weighing uses a hook scale or a scale. At present, there are hook scales, Bluetooth scales, and electronic scales on the market, but most of them are large and inconvenient to carry. The folding electronic scale in the related art adopts a Z-type or N-type foldable scale body to make the electronic scale more convenient to carry. However, the folding scale body has a large spacing area between the support arms after unfolding. When weighing soft packages such as textile packages such as clothing, the package is easy to touch the ground at the position of the spacing area, resulting in inaccurate weighing data.

[0037] Based on the above considerations, the utility model proposes a foldable electronic scale, in which at least one support member is installed on a foldable scale body, and the support member can move relative to the foldable scale body, so that at least part of the support member is located in the interval space in the unfolded state through movement relative to a support arm. The support member is used to support a package to prevent the package from touching the ground in the interval space, thereby improving the accuracy of weighing.

[0038] According to the embodiment of the present utility model, please combine Figure 1 , Figure 3 and Figure 4As shown, a foldable electronic scale 100 is proposed, and the foldable electronic scale 100 includes a foldable scale body 10 and at least one support member 20, wherein the foldable scale body 10 includes at least two support arms, and the at least two support arms are rotatably connected in sequence, so that the foldable scale body 10 can be converted between the folded state and the unfolded state. It can be understood that in the two rotatably connected support arms, when one of the support arms rotates relative to the other support arm, the angle between the two support arms changes. In the process of transitioning from the folded state to the unfolded state, the angle between the two support arms gradually increases, so as to facilitate weighing of objects such as packages in the unfolded state. It should also be noted that in the unfolded state, a spacing space 101 is formed between the two support arms.

[0039] The number of support arms can be set to two, three or more than three. When the number of support arms is two, the foldable scale body 10 is in an I-shape in the folded state and in a V-shape in the unfolded state; when the number of support arms is three, the foldable scale body 10 is in an I-shape in the folded state and in an N-shape in the unfolded state; when the number of support arms is four, the foldable scale body 10 is in an I-shape in the folded state and in an M-shape in the unfolded state. It is understandable that the number of support arms can also be five or more, which will not be listed here one by one.

[0040] Furthermore, at least one support arm is provided with at least one support member 20, and the support member 20 is movably connected to the support arm so that the support member 20 can move relative to the support arm. When the foldable scale body 10 is unfolded, the support member 20 can move relative to the support arm and form a support structure in the interval space 101, so that the support member 20 can support the package to be weighed, prevent the package from touching the ground in the interval space 101, and improve the accuracy of weighing.

[0041] The movement of the support member 20 relative to the support arm includes various relative movement modes such as the support member 20 rotating relative to the support arm, or the support member 20 making linear reciprocating movements relative to the support arm. The present embodiment does not specifically limit the specific movement mode between the support member 20 and the support arm, as long as the relative position between the support member 20 and the support arm changes and at least part of the support member 20 can move to the spacing space 101.

[0042] The support member 20 may be a plate-shaped member or a rod-shaped member, or the support member 20 may also be a retractable telescopic rod. For example, in some embodiments, the support member 20 is a telescopic rod (not shown in the figure), one end of the telescopic rod is arranged on the support member 20, and the telescopic rod includes a plurality of telescopic segments which are sequentially sleeved. When the foldable scale body 10 is in the folded state, the plurality of telescopic segments are contracted, and when the foldable scale body 10 is in the unfolded state, the plurality of telescopic segments are extended, and at least part of the telescopic segments extend to the interval space 101 between the support arms, so that the support member 20 can be used to support the package to be weighed, and the package can be prevented from touching the ground at the interval space 101, thereby improving the accuracy of weighing.

[0043] In some embodiments, please combine Figure 1 , Figure 3 and Figure 4 As shown, the support member 20 is a rod-shaped member, one end of which is rotatably connected to the support arm. When the foldable scale body 10 is in a folded state, the support member 20 overlaps with the support arm, so that the foldable electronic scale 100 is in an I-shape as a whole. When the foldable scale body 10 is in an unfolded state, the support member 20 can rotate relative to the support arm. The support member 20 rotates to a position perpendicular to or at an angle to the support arm, so that at least part of the support member 20 is located in the spacing space 101, so that the support member 20 can support the package to be weighed, prevent the package from touching the ground in the spacing space 101, and improve the accuracy of weighing.

[0044] In some embodiments, the foldable electronic scale 100 includes a support member 20 rotatably disposed on a support arm.

[0045] In other embodiments, the foldable electronic scale 100 includes two support members 20 , and the two support members 20 are rotatably disposed on one support arm together, or the two support members 20 are rotatably disposed on two support arms respectively.

[0046] In other embodiments, the foldable electronic scale 100 includes a plurality of support members 20 , and all the support members 20 are rotatably disposed on one support arm, or each support arm is respectively provided with at least one support member 20 .

[0047] In some embodiments of the present invention, please combine Figure 2 , Figure 6 and Figure 7As shown, the support arm is provided with a containing structure 14. In the folded state, the support member 20 is stored in the containing structure 14. In the unfolded state, the support member 20 rotates relative to the support arm so that at least part of the support member 20 extends from the containing structure 14 to the spacing space 101, so that the support member 20 can support the package to be weighed, prevent the package from touching the ground at the spacing space 101, and improve the weighing accuracy. In this embodiment, by providing the containing structure 14 on the support arm, the support member 20 can be stored in the containing structure 14 of the support arm in the folded state, and the situation that the support member 20 is accidentally touched by an external object in the folded state and causes the support member 20 to be unfolded can be avoided, so that the overall structure of the foldable electronic scale 100 is more compact, the appearance is more concise, and it is easy to carry.

[0048] Understandably, based on the structural shape of the support member 20 and the different connection methods between the support member 20 and the support arm, the storage structure can be set to different structural forms. For example, in some embodiments, the support member 20 is a retractable telescopic rod, and the storage structure is set as a cavity structure formed in the support arm, and the cavity structure forms an opening on the side of the support arm, and the telescopic rod is telescopically fixed to the inner wall of the cavity structure, and one end of the telescopic rod can extend out of the cavity structure through the opening or retract into the cavity structure through the opening. In some embodiments, the support member 20 is a rod-shaped member, and the support member 20 is rotatably connected to the support arm, and the storage structure is set as a long strip of groove-shaped structure, and the support member 20 can be rotated to the outside of the groove-shaped structure or stored in the groove-shaped structure through the opening side of the groove-shaped structure.

[0049] In this embodiment, please combine Figure 1 , Figure 3 and Figure 4As shown, at least two movably connected support arms include a first support arm 11, a second support arm 12, and a third support arm 13. Specifically, the first support arm 11 includes a first main body 111 and a first connecting body 112, and the third support arm 13 includes a second main body 131 and a second connecting body 132. The first main body 111, the second main body 131, and the second support arm 12 are all in the shape of a rectangular parallelepiped rod. The first connecting body 112 is disposed at one end of the first main body 111, and the second connecting body 132 is disposed at one end of the second main body 131. A portion of the contour of the first connecting body 112 is protruded toward one side of the third support arm 13, and a portion of the contour of the second connecting body 132 is protruded toward one side of the first support arm 11. The opposite ends of the second support arm 12 are pivotally connected to the first connecting body 112 and the second connecting body 132, respectively. When the foldable scale body 10 is in the folded state, the second support arm 12, the first body 111, and the second body 131 are arranged in parallel with each other, the second support arm 12 is clamped between the first support arm 11 and the third support arm 13, and the foldable scale body 10 is in the shape of an I; when the foldable scale body 10 is in the unfolded state, the first body 111 and the second body 131 are arranged in parallel with each other, and the second support arm 12 is arranged at an angle to the first body 111 and the second body 131, respectively, so that the foldable scale body 10 is in the shape of an N.

[0050] The opposite ends of the second support arm 12 are pivotally connected to the first support arm 11 and the third support arm 13 respectively, which means that the second support arm 12 is pivotally connected to the first support arm 11 through the first rotating shaft, so that the second support arm 12 can rotate relative to the first support arm 11 around the axis of the first rotating shaft, and the second support arm 12 is pivotally connected to the third support arm 13 through the second rotating shaft, so that the second support arm 12 can rotate relative to the third support arm 13 around the axis of the second rotating shaft. The axis of the first rotating shaft is parallel to the axis of the second rotating shaft.

[0051] Furthermore, the number of the support members 20 is two, and the foldable electronic scale 100 further includes two third rotating shafts, each support member 20 is rotatably connected to the second support arm 12 through a third rotating shaft, the axes of the two third rotating shafts are parallel, and the axes of the third rotating shafts are parallel to or arranged at an angle to the axis of the second rotating shaft. Along the axial direction parallel to the third rotating shaft, the two support members 20 are rotatably mounted on two opposite sides of the second support arm 12. The support member 20 can rotate relative to the second support arm 12 around the third rotating shaft, so that the support member 20 can be transformed with the second support arm 12 between an overlapping state and an unfolded state. For example, in the process of unfolding the foldable electronic scale 100, the foldable scale body 10 in the folded state is first unfolded, at which time the support member 20 and the second support arm 12 are in an overlapping state in the axial direction of the third rotating shaft, and then the support member 20 is rotated relative to the second support arm 12 so that the support member 20 and the second support arm 12 form an angle, and one of the two support members 20 rotates to the interval space 101 between the first support arm 11 and the second support arm 12, and the end of the support member away from the second support arm 12 abuts against the first support arm, and the other of the two support members 20 rotates to the interval space 101 between the second support arm 12 and the third support arm 13, and the end of the support member 20 away from the second support arm 12 abuts against the third support arm, the first support arm 11, the second support arm 12, the third support arm 13 and the two support members 20 can jointly support the package to be weighed, and use the support member 20 to support the package to be weighed to prevent the package from touching the ground at the interval space 101, thereby improving the accuracy of weighing.

[0052] Furthermore, please combine Figure 1 , Figure 6 and Figure 7 As shown, the accommodating structure 14 includes a first groove 141 provided on the first support arm 11. In the folded state, at least part of the second support arm 12 and at least part of the support member 20 are accommodated in the first groove 141. In this embodiment, by providing the first groove 141 on the first support arm 11, the second support arm 12 and the support member 20 can be accommodated in the first groove 141 together in the folded state. Therefore, the situation that the support member 20 is accidentally unfolded due to an external object touching the support member 20 in the folded state can be avoided, so that the overall structure of the foldable electronic scale 100 is more compact, the appearance is more concise, and it is easy to carry.

[0053] Furthermore, please combine Figure 1 , Figure 6 and Figure 7As shown, the accommodating structure 14 further includes a second groove 142 provided on the third support arm 13, and the second groove 142 is arranged opposite to the first groove 141. In the folded state, the second support arm 12 and the support member 20 are received in the first groove 141 and the second groove 142. In this embodiment, by providing the second groove 142 on the second support arm 12, the second support arm 12 and the support member 20 can be received in the first groove 141 and the second groove 142 together in the folded state. Therefore, the situation that the support member 20 is accidentally unfolded due to an external object touching the support member 20 in the folded state can be avoided, so that the overall structure of the foldable electronic scale 100 is more compact, the appearance is more concise, and it is easy to carry.

[0054] Specifically, the first groove 141 sequentially passes through the first main body 111 and the first connecting body 112 along the length direction of the first support arm 11, one end of the second support arm 12 is inserted into the first groove 141 and is pivotally connected to the first connecting body 112 through the first rotating shaft, the second groove 142 sequentially passes through the second main body 131 and the second connecting body 132 along the length direction of the third support arm 13, the other end of the second support arm 12 is inserted into the second groove 142 and is pivotally connected to the second connecting body 132 through the second rotating shaft. The above structure enables the foldable electronic scale 100 to be in a folded state, and the second support arm 12 and the support member 20 provided on the second support arm 12 can be completely received in the first groove 141 and the second groove 142, and the first main body 111 fits with the second main body 131, so that the overall appearance of the foldable electronic scale 100 is smoother, which is convenient for carrying.

[0055] Furthermore, the foldable electronic scale 100 also includes a display module 30 and a weighing sensor module arranged on the support arm. The weighing sensor module is used to detect the weight of the package to be tested and output the weight detection data of the package to be tested to the display module 30. The display module 30 is a display screen, and the display module 30 is used to display the weight data detected by the weighing sensor module.

[0056] In some embodiments, please combine Figure 1 , Figure 4 and Figure 5As shown, the weighing sensor module includes a plurality of first weighing sensors 41 and a plurality of scale feet 42, the scale feet 42 are movably arranged at the bottom of the support arm, and each scale foot 42 is connected to a first weighing sensor 41. The scale foot 42 is movably arranged at the bottom of the support arm, including the scale foot 42 being rotatably arranged on the support arm or slidably arranged on the support arm, and the scale foot 42 serves as the bottom support structure of the foldable electronic scale 100. When the foldable electronic scale 100 is placed on a plane, the scale foot 42 is in contact with the ground. The first weighing sensor 41 is arranged inside the support arm, and one end of the scale foot 42 extends into the inside of the support arm and is connected to the first weighing sensor 41. During the weighing process of the foldable electronic scale 100, the foldable electronic scale 100 is first unfolded and placed on a flat surface, and then the package to be weighed is placed on the top of the foldable electronic scale 100. Under the action of gravity, the gravity of the package to be weighed is transmitted to the flat surface through the support arm, the first weighing sensor 41 and the scale foot 42, so that the weight data of the package to be weighed is measured using the first weighing sensor 41.

[0057] It is understandable that the number of the scale feet 42 is set to at least three, and the foldable electronic scale 100 is stably supported by three or more scale feet 42 .

[0058] In this embodiment, a plurality of scale feet 42 and a plurality of first weighing sensors 41 are respectively disposed on the first supporting arm 11 and the second supporting arm 12 .

[0059] The first weighing sensor 41 includes but is not limited to a resistive strain gauge, a pressure sensor and an elastic element sensor. Among them, the resistive strain gauge is one of the most commonly used weighing sensors at present. It measures weight based on the principle that the resistance value of a metal resistor changes when it is compressed or stretched. The resistive strain gauge has high precision and good stability, and can achieve accurate measurement of tiny weights. The pressure sensor determines the weight by measuring the change in stress or pressure, with high precision and reliability, and relatively low cost. The elastic element sensor is a commonly used pressure measurement sensor, which measures weight by measuring the elastic deformation degree of the measuring element, and it is small in size, highly reliable, and relatively low in cost, but has average precision and often requires temperature correction.

[0060] In some embodiments, the first load cell 41 is a pressure sensor.

[0061] Furthermore, the weighing sensor module includes a second weighing sensor and a hook 44, wherein the second weighing sensor is disposed at one end of a support arm, and the hook 44 is connected to the second weighing sensor. The hook 44 includes a hook portion 441 and a connecting rod portion 442 connected to the hook portion 441, wherein the connecting rod portion 442 is slidably disposed on the support arm, and the second weighing sensor is disposed inside the support arm, and the connecting rod portion 442 is connected to the second weighing sensor. During the weighing process of the foldable electronic scale 100, the package to be weighed is directly hooked on the hook 44, and under the action of gravity, the gravity of the package to be weighed is transmitted to the second weighing sensor through the connecting rod portion 442, thereby using the second weighing sensor to measure the weight data of the package to be weighed.

[0062] The second weighing sensor includes but is not limited to a resistive strain gauge, a pressure sensor and an elastic element sensor.

[0063] In some embodiments, the second load cell is a spring element sensor.

[0064] Furthermore, if Figure 1 and Figure 2 As shown, the foldable electronic scale 100 also includes a tape measure 50, a tape measure slot (not shown) is provided on the third support arm 13, an opening connected to the tape measure slot is provided on the outer wall surface of the third support arm 13, and the tape measure 50 is provided in the tape measure slot, and the tape measure 50 can extend out of the tape measure slot through the opening. By setting the tape measure 50, the tape measure 50 can measure the length, width, height and other data of the express. Among them, the tape measure 50 can be an electronic tape measure 50 with automatic reading, or an ordinary tape measure 50 with manual reading. In this embodiment, the tape measure 50 is an electronic tape measure 50.

[0065] Furthermore, the foldable electronic scale 100 further includes a wireless data transmission module, which is electrically connected to the weighing sensor module and / or the measuring tape 50. The wireless data transmission module can enable the scale to be paired with a display terminal device and transmit weighing weight or volume measurement data. The display terminal device includes but is not limited to a mobile phone and a computer.
