Description

Technical Field

[0001] This invention relates to the technical field of electronic scales, and in particular to a modular electronic scale. Background Technology

[0002] Electronic scales are mainly used to weigh items. When an item is placed on the weighing pan, its weight is applied to the load cell, causing the load cell to undergo elastic deformation, which in turn causes a change in its internal impedance or voltage, outputting an electrical signal. This electrical signal is processed and converted into a digital signal, which is then processed by a processor to display the weight value at the desired location.

[0003] Existing electronic scales include the scale body, the weighing pan, a support rod mounted on the scale body, and a display module mounted on the support rod. However, most electronic scales on the market are distributed or used as complete units after manufacturing. Especially when after-sales service is needed, due to the complexity of the device's structure, most end-users lack the ability to repair or replace parts, requiring the entire device to be sent to an after-sales service center. This not only incurs significant costs but also risks further damage during shipping. Furthermore, most current display angle adjustments are unidirectional, primarily designed to accommodate users of different heights. However, when consumers want to view information on the display, they may need to rotate the entire scale, leading to the following problems: First, the scale is relatively heavy, making rotation inconvenient; second, rotating the scale can cause it to shift, requiring readjustment to a higher level.

[0004] In view of this, the inventors proposed a modular electronic scale, and this invention arises from this. Summary of the Invention

[0037] To make the technical problems, solutions, and beneficial effects of this invention clearer and more understandable, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] Please see Figures 1 to 21This invention provides a modular electronic scale, comprising a scale body 10, a weighing pan body 20 mounted on the scale body 10, a connecting device 30 mounted on the scale body 10, a support rod 40 mounted on the connecting device 30, an adjusting device 50 mounted on the support rod 40, and a display 60 mounted on the adjusting device 50. The scale body 10 includes a housing 11 and a first support 12 disposed within the housing 11, the first support 12 having four support arms 121. The weighing pan body 20 includes a weighing pan body 21 and four support legs 22 disposed below the weighing pan body 21, the four support legs 22 being respectively disposed on four supports. The display 60, under the action of the adjusting device 50, has at least one direction of rotation. This modular electronic scale, by configuring the scale into multiple modules, allows for easy replacement or repair of parts by sending only the faulty module for after-sales service, eliminating the need to ship the entire scale, reducing shipping costs, and avoiding further damage to the equipment.

[0039] Please refer to the details. Figure 1-3 The connecting device 30 is mounted on the main body 10 of the electronic scale. The upright 40 is detachably connected to the connecting device 30 via the first locking member 70. The adjusting device 50 is located on the back of the display 60 and is detachably connected to the upright 40 via the second locking member 80. The connecting device 30 is mounted on the main body 10 of the electronic scale via the first fixing member 15 to form module one. The weighing pan body 20 is module two, the upright 40 is module three, and the adjusting device 50 is mounted on the back of the display 60 via the second fixing member 61 to form module four. Of course, the power supply and communication between the modules are achieved using quick-connect connectors, so each module can be disassembled with simple operation. If a module has a problem, only the corresponding module needs to be sent.

[0040] Please refer to the details. Figure 4 The outer casing 11 has four first through holes 111 communicating with its interior. Four support legs 22 pass through the corresponding first through holes 111 and rest on the corresponding four support arms 121. The weighing pan body 20 also includes dustproof rings 23 on the support legs 22, with each of the four dustproof rings corresponding to one of the four support legs 22. At least two first limiting steps 223 are provided on each support leg 22 to prevent the dustproof rings 23 from falling off. Therefore, by providing dustproof rings 23 on the support legs 22 to reduce the gap between the support legs 22 and the outer casing 11, dust entry into the outer casing 11 can be reduced. Simultaneously, the limiting steps on the support legs 22 prevent the dustproof rings 23 from falling off when the weighing pan body 21 is lifted. The dustproof rings 23 can be made of plastic, and a small gap is left between the inner side of the dustproof ring 23 and the support legs 22 to ensure the free movement of the support legs 22.

[0041] Please refer to the details. Figure 5-7The support foot 22 includes a first connecting part 221 connected to the weighing pan body 20, a second connecting part 222 disposed below the first connecting part 221, a first limiting step 223 located outside the first connecting part 221, and a dustproof ring 23 located outside the first connecting part 221 and above the first limiting step 223, covering a portion of the first through hole 111. The outer diameter of the second connecting part 222 gradually decreases from the first connecting part 221 toward the end face of the second connecting part 222, and its cone angle is α. The electronic scale body 10 also includes a support pad 13 disposed on the first bracket 12, four support pads 13 are disposed corresponding to the support arm 121, and the support foot 22 can be embedded in the support pad 13 below; the support pad 13 can be made of rubber.

A second limiting step 132 is provided above the outer side of the support pad 13, and a third limiting step 133 is provided below the outer side. The third limiting step 133 passes through the second through hole 122 and is located below the support arm 121. The upper and lower outer edges of the third limiting step 133 are chamfered to facilitate better installation of the support pad 13 onto the support arm. The inner diameter of the third through hole 131 gradually decreases from top to bottom, with an angle of β. That is, the inner diameter of the third through hole 131 gradually decreases from the second limiting step 132 toward the third limiting step 133, and the included angle of the cross-section is β, where α is greater than β, for example, α is 2° and β is 1°. By using an α greater than β setting, the support foot 22 can be better supported.

[0042] Please see Figure 1 , 4 The electronic scale device also includes four first feet 16 located below the outer casing 11. The first feet 16 are located below the outer casing 11 and near the four corners. The outer casing 11 includes an upper casing and a bottom casing.

The adjustment device 50 can make the display 60 rotate vertically by setting the first rotating seat 52, making it easier for consumers to view the display 60; at the same time, it can also make the display 60 rotate horizontally by setting the second rotating seat 54, which can adjust the angle of the display 60 and make it easier for people of different heights to operate.

[0051] Please refer to the details. Figure 12-14 The first fixed base 51 is mounted above the upright 40 via the second locking member 80; the second rotating base 54 is mounted on the back of the display 60 via the second fixing member 61. The end face of the upright 40 has a second locking hole 42 for engaging with the second locking member 80, and the back of the display 60 has a second fixing hole for engaging with the second fixing member 61. The first fixed base 51 has a first hole through which the second locking member 80 passes, and the second rotating base 54 has a second hole through which the second fixing member 61 passes. Both the second locking member 80 and the second fixing member 61 are bolts, and at least two bolts are used for each. The second locking hole 42 and the second fixing hole are both threaded holes. After the second locking member 80 passes through the first hole, it is threaded into the second locking hole 42; after the second fixing member 61 passes through the second hole, it is threaded into the second fixing hole. This allows the display 60 to be mounted on the upright 40 via the adjustment device 50. Another way to install the second rotating base 54 is as follows: two first buckles are provided on one side of the second rotating base 54, and a first slot for the buckles to be inserted is provided on the back of the display 60. After the first buckle is inserted into the first slot, two second fixing parts 61 are threaded through the second hole and connected to the second fixing hole. Therefore, only two second fixing parts 61 are needed to fix the display 60 on the second rotating base 54, so as to achieve quick and convenient installation.

[0052] Please refer to the details. Figure 14The first connecting assembly 53 includes a first rotating shaft core 531 and a first rotating bushing 532 connected to the first rotating shaft core 531. The first rotating shaft core 531 passes through a first rotating seat 52 and a first fixed seat 51 before connecting to the first bushing. The first rotating shaft core 531 and the first bushing are connected by a thread. The first rotating shaft core 531 has a first annular step at the top and external threads at the bottom. The first bushing has internal threads, thus achieving the threaded connection between the first rotating shaft core 531 and the first bushing.

[0053] Please refer to the details. Figure 14 , 15The first connecting assembly 53 further includes a first damping assembly 533 disposed between the first fixed seat 51 and the first rotating shaft sleeve 532. The first rotating shaft core passes through the first transmission seat, the first fixed seat 51, and the first damping assembly 533 before connecting to the first rotating shaft sleeve 532. The first damping assembly 533 includes a first wear-resistant plate 5331, a first spring plate 5332, and a second wear-resistant plate 5333, which are arranged sequentially. At least one first spring plate 5332 is provided; in this invention, two are used. The first connecting assembly 53 also includes a first limiting seat 534 disposed between the first rotating seat 52 and the first fixed seat 51 to limit the rotation angle of the first rotating seat 52. Specifically, the first fixed seat 51 is provided with a fourth limiting step 511 for limiting the rotation of the first limiting seat 534, and the first limiting seat 534 is provided with a first limiting groove 5341 along its outer side wall. The first limiting groove 5341 determines the rotational stroke of the first limiting seat 534. The first spring 5332 primarily provides damping, while the first wear-resistant plate 5331 and the second wear-resistant plate 5333 provide wear resistance. It is preferable to have two first springs 5332; when compressed, they generate elasticity, preventing the first rotating seat 52 from rotating on its own and requiring manual external force to rotate. The first rotating shaft core passes sequentially through the first rotating seat 52, the first limiting seat 534, the first fixed seat 51, and the first damping component 533 before connecting to the first rotating shaft sleeve 532. The first annular step of the first rotating shaft core, in conjunction with the first rotating shaft sleeve 532, ensures the sequential arrangement and tight fit of the first rotating seat 52, the first limiting seat 534, the first fixed seat 51, and the first damping component 533. The first rotating seat 52, the first fixed seat 51, the first limiting seat 534, the first wear-resistant plate 5331, the first spring plate 5332, and the second wear-resistant plate 5333 are all provided with a fourth hole for the first rotating shaft core to pass through. At least one first planar position is provided on the outer wall of the first rotating shaft core. A second planar position is provided on the inner side of the first rotating seat 52, the first limiting seat 534, the first wear-resistant plate 5331, the first spring plate 5332, and the second wear-resistant plate 5333 corresponding to the first planar position. Therefore, when the first rotating seat 52 rotates, the first rotating shaft core, the first limiting seat 534, the first damping assembly 533, and the first rotating bushing 532 all rotate accordingly. The present invention provides two first planar positions, symmetrically located on the outer wall of the first rotating shaft core, and two corresponding second planar positions to ensure stable rotation. The first rotating shaft core is hollow inside, allowing cables to pass through.

The two fourth connecting portions 521 are located inside the two fifth connecting portions 541. The fourth connecting portions 521 have first mounting holes 5211 for connecting the second connecting assembly 55, and the fifth connecting portions 541 have second mounting holes 5411 for connecting the second connecting assembly 55. One end of the second rotating shaft core 551 has a second annular step, and the other end is provided with external threads. The inner side of the second rotating shaft sleeve 552 is provided with an internal threaded hole so that the second rotating shaft core 551 and the second rotating shaft sleeve 552 are threadedly connected.

[0056] Please refer to the details. Figure 13 , 14 16, 17. The adjacent fourth connecting portion 521 and fifth connecting portion 541 are connected by a set of second connecting components 55. Therefore, there are two sets of second connecting components 55. The third wear-resistant plate 5531 is disposed on both sides of the fourth connecting portion 521, and the fourth wear-resistant plate 5532 is disposed on both sides of the fifth connecting portion 541. Two of each of the third and fourth wear-resistant plates 5531 and 5532 are provided, and their shape is the same as the first wear-resistant plate 5331, except for their size. Furthermore, the inner sides of the third and fourth wear-resistant plates 5531 and 5532 do not have a second planar surface. Please refer to [link / reference] for details. Figure 18In this invention, the third wear-resistant plate 5531 and the fourth wear-resistant plate 5532 can also be constructed as follows: the two third wear-resistant plates 5531 adopt an integral structure, and the sidewalls of the two third wear-resistant plates 5531 are connected by a first connecting block. At the same time, a second slot 5212 for embedding the first connecting block is provided on the fourth connecting part 521. The two fourth wear-resistant plates 5532 also adopt an integral structure and are connected by a second connecting block. At the same time, a third slot 5412 for embedding the second connecting block is provided on the fifth connecting part 541. By adopting an integral structure for the third wear-resistant plates 5531 and the fourth wear-resistant plates 5532, the installation efficiency can be improved. During installation, the first connecting block is embedded in the fourth connecting part 521, and the second connecting block is embedded in the fifth connecting part 541.

[0057] Please refer to the details. Figure 17 , 18 The outer wall of the second rotating shaft core 551 is provided with at least one third plane position, and the inner side of the second mounting hole 5411 is provided with a fourth plane position corresponding to the third plane position. The inner sides of the third wear-resistant plate 5531, the fourth wear-resistant plate 5532, the second spring 5533, and the fourth gasket are all provided with fifth holes for the second rotating shaft core 551 to pass through. During installation, the third wear-resistant plate 5531 is installed on the fourth connecting part 521 through the first connecting block, and the fourth wear-resistant plate 5532 is installed on the fifth connecting part 541 through the second connecting block.

[0059] Please refer to the details. Figure 14 , 21Two third fixing posts 561 are provided on the inner side of the decorative cover 56, and are set on the second rotating seat 54 through the fourth fixing member 57. Specifically, the third fixing posts 561 are provided with internal threads, the fourth fixing member 57 is a bolt, and the second rotating seat 54 is provided with a third hole for the third locking member 35 to pass through. After the fourth fixing member 57 passes through the third hole, it is threadedly connected to the third fixing posts 561 so that the decorative cover 56 can be installed on the second rotating seat 54, thus serving both decorative and protective functions.

[0060] Please refer to the details. Figure 19 , 20 The cross-sections of the first spring 5332 and the second spring 5533 are inclined from the outside to the inside. When the two first springs 5332 or the two second springs 5533 are placed side by side, they have a certain degree of elasticity.

[0061] In summary, the modular electronic scale of the present invention, by setting the electronic scale into multiple modules, allows for easy replacement or repair of parts by sending only the faulty module for after-sales service, eliminating the need to ship the entire unit, thus reducing shipping costs and preventing further damage to the equipment. Furthermore, firstly, by providing dustproof rings on the support legs to reduce the gap between the support legs and the outer casing, dust ingress into the casing is minimized. Secondly, by providing limiting steps on the support legs, the dustproof rings are prevented from falling off when the weighing pan is lifted. Moreover, the connecting device of the present invention, by providing a second bracket on the base and connecting the bottom of the upright to the second bracket, and the side wall to the base, ensures stable installation of the upright. Thirdly, the adjustment device, by providing a first rotating seat, allows the display to rotate vertically for easy viewing by the consumer; simultaneously, a second rotating seat allows the display to rotate horizontally, adjusting the display angle.
