[0025] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0027] like Figure 1-8 As shown, an electronic scale that generates electricity by compressing its weighing feet includes a scale body 1. Inside the scale body 1, on both sides, are a first weighing support assembly 2 and a second weighing support assembly 3, which can be raised and lowered relative to the scale body 1. The scale body 1 contains a gear set 4 and a generator 5. The output end of the gear set 4 is connected to the power input end of the generator 5. The first weighing support assembly 2 includes a first connecting seat 21 with multiple circumferentially distributed limiting holes 22. Inside the scale body 1, there are multiple positioning posts 23 arranged along the lifting direction of the first weighing support assembly 2 and fitted into the limiting holes 22. A spring 24 is provided on the positioning post 23 between the upper inner side of the scale body 1 and the first connecting seat 21. A rack 6, arranged along the lifting direction, is fixed to the outer side of the first connecting seat 21. The rack 6 meshes with the input end of the gear set 4 so that when the first weighing support assembly 2 is raised and lowered relative to the scale body 1, it drives the generator 5 to generate electricity. After the scale body 1 is pressed down, both the first weighing support assembly 2 and the second weighing support assembly 3 can be displaced relative to the scale body 1 to achieve power generation and weighing. In this process, after the scale body 1 is pressed down, the first connecting seat 21 in the first weighing support assembly 2, with the cooperation of the limiting hole 22 and the positioning post 23, causes the first connecting seat 21 and the rack 6 to move in the lifting direction relative to the scale body 1. At the same time, the spring 24 is compressed, and the rack 6 drives the gear set 4 to transmit power to the generator 5. After the scale body 1 is no longer compressed, each spring 24 returns to its original position, causing the first connecting seat 21 to return to its original position, and the first weighing support assembly 2 to return to its original position. By setting multiple limiting holes 22 circumferentially on the first connecting seat 21 of the first weighing support assembly 2, setting multiple positioning posts 23 and multiple return springs 24 in the scale body 1, the first weighing support assembly 2 can smoothly move in the lifting direction relative to the scale body 1 to generate electricity, avoiding skew and jamming that would affect power generation and weighing accuracy.

[0028] like Figure 5 As shown, the gear set 4 includes multiple stages of gears meshing sequentially. The multiple gears on the rear side are housed with the generator 5 in the housing to improve meshing tightness, and the power generation of the rack during short stroke is increased by setting up double gears.

[0029] like Figure 2-6As shown, a load-bearing plate 7 is provided inside the scale body 1 on one side of the first weighing support component 2. The first weighing support component 2, gear set 4 and generator 5 are all arranged on the lower side of the load-bearing plate 7. The positioning post 23 is arranged on the lower side of the load-bearing plate 7. The spring 24 is arranged between the lower side of the load-bearing plate 7 and the first connecting seat 21, so that the first weighing support component 2, gear set 4 and generator 5 are arranged on the load-bearing plate 7 as a whole. This facilitates the tight cooperation between the first weighing support component 2, gear set 4 and generator 5 and allows them to be quickly assembled into the scale body 1. At the same time, the load-bearing plate 7 allows each first weighing support component 2 on the same side to be evenly stressed, so that each first weighing support component 2 can move smoothly up and down relative to the scale body 1.

[0030] like Figure 2-6 As shown, the outer side of the first connecting seat 21 is provided with multiple outwardly extending and circumferentially distributed connecting seat protrusions 25. Limiting holes 22 are provided on the connecting seat protrusions 25. Springs 24 are provided between the lower side of the load-bearing plate 7 and the connecting seat protrusions 25 for easy quick assembly. The inner side of the base 12 is provided with multiple base buckles 14 and multiple limiting protrusions 15 supporting the load-bearing plate 7. The lower side of the load-bearing plate 7 is provided with multiple load-bearing plate buckles 71 that cooperate with the base buckles 14, which facilitates the quick assembly of the load-bearing plate 7 together with the first weighing support assembly 2, gear set 4 and generator 5 into the scale body 1. The assembly and disassembly are convenient and maintenance is easy.

[0031] like Figure 1-8 As shown, the scale body 1 includes a bearing panel 11 and a base 12. The load-bearing plate 7 is disposed on the base 12, and a receiving cavity is formed between the load-bearing plate 7 and the base 12. The first weighing support assembly 2, the gear set 4 and the generator 5 are disposed in the receiving cavity. The base 12 is provided with a base through hole 13 for the support ends of the first weighing support assembly 2 and the second weighing support assembly 3 to pass through.

[0032] like Figure 2-6 As shown, the first weighing support assembly 2 also includes a first sensor 26 and a first support foot 27. The first sensor 26 is disposed on the lower side of the first connecting seat 21, and its weighing detection end contacts the upper side of the first support foot 27. The upper outer surface of the first support foot 27 has multiple outwardly extending and circumferentially distributed elastic arms 28. The other end of each elastic arm 28 is connected to the lower side of the first connecting seat 21. A connector 29 is connected to the lower side of the weighing detection end of the first sensor 26. The lower side of the connector 29 has a downwardly protruding protrusion 210. The upper side of the first support foot 27 has a pressure plate 211 that contacts the protrusion 210. Figure 7-8As shown, the second weighing support assembly 3 includes a second connecting seat 31, a second sensor 32, and a second support foot 33. The second connecting seat 31 is connected to the base 12. The second sensor 32 and the second support foot 33 are sequentially arranged on the lower side of the second connecting seat 31, and the upper side of the second support foot 33 is in contact with the weighing detection end of the second sensor 32. At the same time, the upper side of the outer side of the second support foot is provided with multiple outwardly extending and circumferentially distributed elastic arms. The other end of the elastic arms is connected to the lower side of the second connecting seat. The lower side of the weighing detection end of the second sensor is connected to a connector. The lower side of the connector is provided with a downwardly protruding protrusion. The upper side of the second support foot is provided with a top pressure plate that contacts the protrusion. In this case, the first connecting seat 21 of the first weighing support assembly 2 can move up and down relative to the scale body 1, while the second connecting seat 31 of the second weighing support assembly 3 is fixed inside the scale body 1. Therefore, in the initial state, the first weighing support assembly is higher than the second weighing support assembly. When the scale body is placed on a horizontal ground, the scale body is not parallel to the horizontal ground, which causes the elastic arm on the support foot to twist and deform, so that the support foot automatically twists to fit with the horizontal ground. The top pressure plate embedded in the support foot will also twist slightly with the support foot, and the protrusion of the sensor connector will always fit, thereby avoiding the situation where the support foot is damaged due to tilting and improving the weighing accuracy.

[0033] like Figure 4-8 As shown, the first support leg 27 has a connecting ring 212 on its outer side, and the other end of the elastic arm 28 is connected to the inner side of the connecting ring 212. The connecting ring 212 has multiple connecting slots 213, and the lower side of the first connecting seat 21 has multiple connecting protrusions 214 that cooperate with the connecting slots 213. The third support leg 33 has a connecting ring on its outer side, and the other end of the elastic arm is connected to the inner side of the connecting ring. The connecting ring has multiple connecting slots, and the lower side of the second connecting seat 31 has multiple connecting protrusions that cooperate with the connecting slots, which allows the support leg to be quickly positioned and installed on the connecting seat.

[0034] like Figure 7-8 As shown, a positioning protrusion 16 and a positioning buckle 17 are provided on the inner periphery of the base through hole 13 on the side where the second weighing support component 3 is installed on the base 12. The positioning protrusion 16 and the positioning buckle 17 extend circumferentially along the base through hole 13. The positioning protrusion 16 has a positioning space, and the second connecting seat 31 is accommodated in the positioning space. The outer side of the second connecting seat 31 has positioning recesses 34 that are respectively engaged with the positioning buckle 17, so that the second weighing support component 3 is fixedly installed on the base 12.

[0035] like Figure 2-3As shown, the supporting panel 11 is rectangular. Two first weighing support components 2 are configured and distributed at the two end corners on the same side of the supporting panel 11, and are respectively connected to the load-bearing plate 7. Two second weighing support components 3 are configured and distributed at the two end corners on the side of the supporting panel 11 away from the first weighing support components 2. In this case, the gear set 4 and generator 5 used for power generation in conjunction with the first weighing support components 2 can be configured as one set, which generates power in conjunction with one of the first weighing support components 2, or they can be configured as two sets, which generate power in conjunction with the first weighing support components 2 on both sides respectively.

[0036] like Figure 2 As shown, the upper side of the load-bearing plate 7 is located at the position of the first weighing support component 2, and the upper side of the second weighing support component 3 is respectively provided with buffer components 8, which play a buffering role on the load-bearing panel 11 and protect the first weighing support component 2 and the second weighing support component 3.
