[0003] This invention overcomes the shortcomings of the prior art and provides a knob-type self-generating electronic scale.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A knob-type self-generating electronic scale is characterized by: a scale body housing, a knob on the scale body housing with its lower end extending into the scale body housing and rotatable relative to the scale body housing, a plurality of knob rotation teeth arranged around the lower outer side of the knob, a gear assembly and a power generation assembly inside the scale body housing, a power generation assembly gear on the rotating shaft end of the power generation assembly, the gear assembly including at least two meshing transmission gears, the input end of the first transmission gear meshing with the knob rotation teeth, and the output end of the last transmission gear meshing with the power generation assembly gear.

[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] 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.

[0026] like Figure 1-5As shown, a knob-type self-generating electronic scale includes a scale housing 1. A knob 2, with its lower end extending into the scale housing 1 and rotatable relative to it, is provided on the scale housing 1. Multiple knob rotation teeth 3 are arranged around the lower outer side of the knob 2. A gear assembly 4 and a power generation assembly 5 are provided inside the scale housing 1. A power generation assembly gear 6 is provided on the shaft end of the power generation assembly 5. The gear assembly 4 includes at least two meshing transmission gears 401. The input end of the first transmission gear 401 meshes with the knob rotation teeth 3, and the output end of the last transmission gear 401 meshes with the power generation assembly gear 6. When the knob 2 is rotated, the knob rotation teeth 3 on the knob 2 drive the first transmission gear 401 of the gear assembly 4 to rotate. The first transmission gear 401 drives the last transmission gear 401 to rotate sequentially, and through the last transmission gear 401, drives the power generation assembly gear 6 to rotate, thereby causing the power generation assembly 5 to rotate and generate electricity. In this case, the knob rotation teeth 3 are set on the outer side of the knob 2, which can greatly increase the number of knob rotation teeth 3 and increase the power generation when the knob is rotated. At the same time, the knob rotation teeth 3 arranged around the knob can drive the transmission gear 401 in the gear assembly 4 to rotate cyclically when the knob 2 rotates in one direction, thereby increasing the power generation without the need to frequently rotate the knob.

[0027] like Figure 3-5 As shown, the gear assembly 4 includes multiple transmission gears 401. The first transmission gear 401 is a single gear structure, while the rear transmission gears 401 are all double gear structures. The first transmission gear 401 includes a driving gear 4011, and the rear transmission gear 401 includes a driving gear 4011 and a driven gear 4012 coaxially arranged with the driving gear 4011. The driven gear 4012 of the front rear transmission gear 401 meshes with the driving gear 4011 of the rear rear transmission gear 401. The driving gear 4011 of the first transmission gear 401 meshes with the knob rotation gear 3 and the driving gear 4011 of the first rear transmission gear 401, respectively. The driven gear 4012 of the last rear transmission gear 401 meshes with the generator component gear 6. In this case, the gear assembly 4 has four transmission gears 401. After the knob rotation gear 3 on knob 2 drives the driving gear 4011 of the first transmission gear 401 to rotate, it simultaneously drives the driving gear 4011 of the second transmission gear 401 to rotate, and causes the driven gear 4012 of the second transmission gear 401 to rotate synchronously. This sequentially drives the transmission gear 401 at the rear end to rotate, and through the driven gear 4012 of the fourth transmission gear 401, it drives the generator component gear 6 to rotate, causing the generator component 5 to rotate and generate electricity. In this design, the knob rotation gear 3, the transmission gear 401 in the gear assembly 4, and the generator component gear 6 are arranged horizontally, with ample space and tight meshing between them. The number of transmission gears and the number of teeth on each gear can be adjusted according to actual needs, thus optimizing the design.

[0028] In this case, the transmission ratio between the knob rotation tooth 3 of knob 2 and the gear 6 of the power generation component is 1 / 250-1 / 310. While meeting the power generation requirements, it also allows for easy and effortless turning, enabling standby time of 3-5 minutes or more after turning half a turn, which fully meets the requirements for normal use.

[0029] like Figure 3-5 As shown, the gear assembly 4 includes a gear mounting base 402 disposed inside the scale housing 1. The gear mounting base 402 is provided with multiple rotating shafts 403, and each transmission gear 401 is respectively disposed on the rotating shaft 403, so that each transmission gear 401 rotates on the corresponding rotating shaft 403. The generator assembly 5 is disposed at the rear end position inside the gear mounting base 402, so that the generator assembly gear 6 is tightly meshed with the end transmission gear 401. The front side of the gear mounting base 402 is provided with a mounting base opening 404 for the first end transmission gear 401 to extend out and mesh with the knob rotation tooth 3, so that the knob rotation tooth 3 on the knob 2 can mesh with the first end transmission gear 401.

[0030] like Figure 1-3 As shown, the scale body housing 1 is provided with a mounting cover 7. The lower end of the knob 2 extends into the scale body housing 1 through the mounting cover 7, which facilitates the installation of components such as the knob 2 and the display screen 9 on the scale body housing 1.

[0031] like Figure 2-3 As shown, the inner bottom surface of the scale body housing 1 is provided with multiple limiting ribs 101 arranged around the lower end of the knob 2; the lower end of the outer side of the knob 2 is provided with a knob groove 21 arranged around and cooperating with the limiting ribs 101; the knob rotation teeth 3 are arranged on the outer side of the knob 2 at the position above the knob groove 201, limiting the knob 2 to rotate within the area surrounded by multiple limiting ribs 101, preventing the knob 2 from moving, thereby ensuring that the knob rotation teeth 3 on the knob 2 accurately mesh with the transmission gear 401 at the head end.

[0032] like Figure 1-3 As shown, the mounting cover 7 is provided with a display screen mounting bracket 8, the gear assembly 4 is located on the lower side of the display screen mounting bracket 8, and the display screen 9 is provided on the display screen mounting bracket 8, so that the display screen 9 is securely installed.

[0033] like Figure 2-3 As shown, the scale housing 1 is provided with multiple weighing components 10, and a main control component 11 that is electrically connected to the power generation component 5, the display screen 9, and the weighing components 10 respectively. The main control component 11 includes electronic components such as rectifiers, energy storage components, voltage regulators, and control chips, and can realize the functions of energy storage, power supply to each power-consuming component, and calculation and control display of weighing data.

[0034] like Figure 2-3As shown, an adhesive is provided between the upper side of the weighing component 10 and the inner side of the weighing housing 1. The weighing deformation end of the weighing component 10 extends through the bottom shell of the weighing housing 1. The adhesive securely sets the weighing component 10 on the inner side of the weighing housing 1, thereby improving weighing accuracy.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
