Through the transmission member 500, when the first support component 200 is lifted or lowered relative to the load-bearing component 100, the power generation component 400 is driven to generate electricity. In this way, the user can press the load-bearing component 100 to lift or lower the first support component 200 relative to the load-bearing component 100, and there is no need to set additional buttons to drive the generator 420 to generate electricity, which can be convenient for users to use. At the same time, when weighing, there is no need for additional action to drive the power generation component 400, and electricity can be generated while weighing.

[0032] Specifically, when generating electricity, the user can press the load-bearing component 100 to make the first support component 200 rise and fall relative to the load-bearing component 100. By setting the transmission member 500, the transmission member 500 drives the gear set 410 to rotate through the rack 510 to drive the power input end of the generator 420 to enable the generator 420 to generate electricity. The structure is simple, and there is no need to set additional buttons to drive the generator 420 to generate electricity, which can facilitate the production of electronic scales. At the same time, when weighing, there is no need for additional action to drive the power generation component 400, and electricity can be generated while weighing, which is convenient for users to use.

When the object is removed from the load-bearing assembly 100, the restoring force of the elastic member 310 can drive the first support assembly 200 to reset, so as to prepare to drive the generator 420 to generate electricity during the next weighing.

[0036] Specifically, by providing the elastic member 310, when the user presses the load-bearing assembly 100, the elastic member 310 can be greatly deformed, so that the connecting shaft moves a sufficient distance to allow the generator 420 to generate sufficient electrical energy, and when the user releases the load-bearing assembly 100, the restoring force of the elastic member 310 can drive the first support assembly 200 to reset, so as to drive the generator 420 to generate electricity at the next weighing. When the pressure sensor 330 is squeezed by the first connecting seat 320 and the load-bearing assembly 100 or the first support assembly 200, it can detect the pressure and calculate the mass of the object.

[0037] It should be noted that the other end of the elastic member 310 can also be connected to the first supporting assembly 200 so as to drive the first supporting assembly 200 to reset, which is not limited here.

When assembling the transmission member 500, the connecting part 520 is aligned with the mounting groove 321, and the limiting part and the limiting hole 322 are located on the same side, and then the connecting part 520 is inserted into the mounting groove 321 and the limiting part is accommodated in the limiting hole 322.

[0048] Specifically, the base 110 can be connected to the supporting plate 120 by bolting or clamping. The base 110 and the supporting plate 120 enclose a accommodating cavity 101, which can protect the power generation component 400 and the first sensor component 300 to prevent the power generation component 400 and the first sensor component 300 from colliding with the outside world. By setting a through hole 121 on the base 110, the first support component 200 can pass through the through hole 121 to be connected to the first sensor component 300. During weighing, the object to be weighed is placed on the supporting plate 120. Under the action of gravity, the supporting plate 120 and the base 110 move downward relative to the first support component 200.

[0049] Reference Figure 6 In some embodiments of the present invention, the diameter of the first connecting seat 320 is greater than the diameter of the through hole 121, so that the first connecting seat 320 can abut against the periphery of the through hole 121, thereby preventing the first connecting seat 320 from detaching from the supporting assembly 100 from the through hole 121.

[0050] Specifically, the first connecting seat 320 and the first supporting assembly 200 are overall T-shaped structures. When assembling the electronic scale, the first sensor assembly 300 and the first supporting assembly 200 are pre-assembled, and then the first supporting assembly 200 is passed through the through hole 121 from top to bottom, and then the base 110 and the supporting plate 120 are assembled by bolting. The first connecting seat 320 can abut against the periphery of the through hole 121, which can prevent the first connecting seat 320 from detaching from the through hole 121 from the supporting assembly 100.

The positioning protrusion 122 is extended along the circumference of the through hole 121. The positioning protrusion 122 is provided with a positioning space. The first connecting seat 320 is accommodated in the positioning space, and the first connecting seat 320 can be circumferentially positioned to avoid the first connecting seat 320 moving left and right relative to the base 110, resulting in an increase or decrease in the matching clearance between the rack 510 and the gear set 410, thereby improving the reliability of the self-generating electronic scale.

[0052] Specifically, the positioning protrusion 122 is arranged on the periphery of the through hole 121, and the positioning protrusion 122 is extended in the direction close to the supporting plate 120, so as to perform circumferential positioning on the first connecting seat 320 to avoid the first connecting seat 320 moving left and right relative to the base 110, resulting in an increase or decrease in the matching clearance between the rack 510 and the gear set 410, thereby improving the reliability of the use of the self-generating electronic scale.

The two first sensor assemblies 300 are distributed at two corners on the same side of the supporting plate 120. Two second sensor assemblies 700 and two second sensor assemblies 700 are respectively configured and connected one by one. The two second support assemblies 600 are distributed at two corners on the side of the supporting plate 120 away from the first sensor assembly 300, so that when a user presses the supporting assembly 100, it is more stable, and the supporting assembly 100 can be avoided from tilting relative to the first support assembly 200 when the supporting assembly 100 is pressed. It can be convenient for the user to press the supporting assembly 100 to make the first support assembly 200 rise and fall relative to the supporting assembly 100, thereby facilitating the generator 420 to generate electricity.

[0054] Specifically, the two first sensor assemblies 300 are located on the same side of the supporting plate 120, and the two second sensor assemblies 700 are located on the side of the supporting plate 120 away from the first sensor assemblies 300. The two first sensor assemblies 300 and the two second sensor assemblies 700 are distributed at the four corners of the supporting plate 120, so that the supporting plate 120 is more stable when carrying objects, thereby making the weighing results more accurate, and the two first sensor assemblies 300 and the two second sensor assemblies 700 can calibrate each other to reduce errors.

[0055] It should be noted that the first sensor assembly 300 may also be configured with one, three, or four, etc., which is not limited here.

The bearing plate 120 is connected to the second connecting seat 140 through the buffer member 130.
