Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] In the description of this utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 、 Figure 5 A self-generating electronic scale proposed in an embodiment of the present invention includes a shell assembly 100, a power generation assembly 200, a transmission rack and a sensor assembly 400. A panel 110 is provided on the shell assembly 100. The panel 110 is used to place the object to be weighed. In addition, a display screen can be provided on the panel 110, and the weighing object can be displayed on the display screen.

[0034] The shell assembly 100 includes a bottom cover 120 and a surface cover 130. The bottom cover 120 and the surface cover 130 are assembled together. A receiving space 140 is formed between the bottom cover 120 and the surface cover 130. The power generation component 200 is arranged in the receiving space 140 of the shell assembly 100. The power generation component 200 includes a power generation gear set 210 and a generator. The power generation gear set 210 can drive the generator to rotate at high speed, thereby enabling the generator to generate electricity.

[0035] The transmission rack is arranged in the housing assembly 100, and the transmission rack is engaged with the input gear of the power generation gear set 210 for transmission. The transmission rack can move or rotate in the housing assembly 100. A first driving member 310 is provided on the transmission rack. The first driving member 310 can drive the transmission rack to move or rotate under the action of external power, so that the transmission rack drives the power generation gear set 210 to rotate.

[0036] The sensor assembly 400 includes multiple sensors 410 and multiple sensor holders 420. In the embodiment shown in the figure, the sensor assembly 400 includes four sensors 410 and four sensor holders 420. The four sensors 410 and the four sensor holders 420 are arranged in a one-to-one correspondence, wherein the sensor holder 420 is arranged in the shell assembly 100, and the sensor 410 is fixedly connected to the sensor holder 420. A supporting foot is provided on the sensor 410, and one end of the supporting foot is located outside the shell assembly 100. The four supporting feet serve to support the scale body of the electronic scale. A second driving member 430 is provided on one of the sensor seats 420, and at least one of the first driving member 310 and the second driving member 430 is provided with an inclined surface. The sensor seat 420 provided with the second driving member 430 can move in the up and down directions. When the sensor seat 420 moves upward along the shell assembly 100, the second driving member 430 cooperates with the inclined surface, and the second driving member 430 drives the first driving member 310 to move in the shell assembly 100, thereby driving the transmission rack to move or rotate in the shell assembly 100 through the first driving member 310. The transmission rack moves or rotates in the shell assembly 100, driving the power generation gear set 210 of the power generation assembly 200 to rotate, thereby driving the generator to generate electricity to supply power to the electronic scale.

[0037] To sum up, when the electronic scale of the present invention is in use, it is only necessary to place the object to be weighed on the panel 110 of the electronic scale. The panel 110 sinks under the action of the weight, and the sensor seat 420 with the second drive member 430 moves upward relative to the shell assembly 100. The second drive member 430 drives the first drive member 310 through the inclined surface, so that the first drive member 310 drives the transmission rack to move or rotate in the horizontal plane, and then drives the power generation component 200 to generate electricity. Therefore, the electronic scale of the present invention does not require additional action to drive the power generation component 200 when in use, and can generate electricity while weighing, which is convenient to use. In addition, since no external drive member is required, the appearance is neat and beautiful.

[0038] Reference Figure 2 、 Figure 6 In the above embodiment, the transmission rack moves or rotates in the housing assembly 100 in a horizontal plane, thereby reducing the thickness of the housing assembly 100 and making the electronic scale thinner.

[0039] It should be noted that, under the condition that the height dimension of the accommodating space 140 of the housing assembly 100 is met, the movement or rotation of the transmission rack in the housing assembly 100 can also be performed in the vertical plane, which is not limited here.

[0040] It is understandable that the number of sensor holders 420 and sensors 410 constituting the sensor assembly 400 can be set according to specific circumstances, and all sensor holders 420 can be configured to be able to move up and down relative to the housing assembly 100, which is not limited here.

[0041] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 In some embodiments, the first driving member 310 is provided with a first inclined surface 311, and the second driving member 430 is provided with a second inclined surface 431, and the second inclined surface 431 is configured to abut against the first inclined surface 311. The cooperation between the first inclined surface 311 and the second inclined surface 431 can increase the contact area between the first driving member 310 and the second driving member 430, thereby improving the assembly stability of the first driving member 310 and the second driving member 430.

[0042] It is understood that, in some embodiments, a first inclined surface 311 is provided on the first driving member 310, and the second driving member 430 is configured in a cylindrical or semi-cylindrical shape, so that the first driving member 310 and the second driving member 430 are in line contact, thereby reducing the frictional resistance between the first driving member 310 and the second driving member 430. Alternatively, in some embodiments, a second inclined surface 431 is provided on the second driving member 430, and the first driving member 310 is configured in a cylindrical or semi-cylindrical shape, so that the first driving member 310 and the second driving member 430 are in line contact, thereby reducing the frictional resistance between the first driving member 310 and the second driving member 430.

[0043] It can be understood that in some embodiments, a slope is provided on one of the driving members and a roller is provided on the other driving member. The roller can roll on the slope to form rolling friction between the first driving member 310 and the second driving member 430 to further reduce the friction resistance between the first driving member 310 and the second driving member 430.

[0044] It can be understood that the slope and length of the first inclined surface 311 can be adjusted. By adjusting the slope and length of the first inclined surface 311 on the first driving member 310, the stroke of the transmission rack can be adjusted, thereby increasing the number of rotations of the generator and thereby improving the efficiency of the generator.

[0045] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 3In some embodiments, the transmission rack is a linear rack 300, which is disposed in the housing assembly 100 and can move horizontally in the housing assembly 100. Thus, a transmission method with inclined plane matching is adopted to convert the up and down movement direction of the sensor holder 420 into horizontal movement of the linear rack 300, thereby changing the movement direction of the transmission rack, which is beneficial to reducing the thickness of the housing assembly 100 and making the electronic scale thinner.

[0046] Reference Figure 3 、 Figure 4 In some embodiments, a guide member 121 is provided in the housing assembly 100, and the linear rack 300 is provided with a guide groove 340. The guide member 121 is provided in the guide groove 340. The guide member 121 and the guide groove 340 can enable the linear rack 300 to move smoothly, thereby improving the stability of the electronic scale.

[0047] Reference Figure 3 、 Figure 4 In some embodiments, a return spring 320 is disposed between the linear rack 300 and the housing assembly 100. One end of the return spring 320 abuts against a sidewall of the housing assembly 100, while the other end of the return spring 320 abuts against one end of the linear rack 300. After use of the electronic scale, the object on the panel 110 is removed, the sensor holder 420 is reset, and the linear rack 300 is reset by the return spring 320, allowing the linear rack 300 to drive the power generation assembly 200 to generate electricity when the electronic scale is used again.

[0048] Reference Figure 5 、 Figure 6 In some embodiments, the transmission rack is an arc-shaped rack 330, which is arranged in the shell assembly 100, and the arc-shaped rack 330 can rotate in a horizontal plane around the rotating shaft 331 in the shell assembly 100. Therefore, a transmission method of inclined plane matching is adopted to convert the up and down movement direction of the sensor seat 420 into the horizontal rotation of the arc-shaped rack 330, which is conducive to reducing the thickness of the shell assembly 100 and making the electronic scale thinner.

[0049] Reference Figure 5 、 Figure 6 In some embodiments, a return spring 320 is provided between the arc-shaped rack 330 and the housing assembly 100. One end of the return spring 320 is connected to the housing assembly 100, and the other end of the return spring 320 is connected to one side of the arc-shaped rack 330. After the electronic scale is used, the object on the panel 110 is removed, the sensor seat 420 is reset, and the arc-shaped rack 330 is reset under the action of the return spring 320, so that the arc-shaped rack 330 can be used to drive the power generation assembly 200 to generate electricity when the electronic scale is used again.

[0050] It is understandable that by changing the position of the rotating shaft 331 of the arc-shaped rack 330, the rotation angle can be amplified, the stroke of the arc-shaped rack 330 can be increased, and the number of rotations of the generator can be increased, thereby improving the efficiency of the generator.

[0051] It is understandable that when the power generation efficiency of the generator needs to be further improved, the slope and length of the inclined surface and the position of the rotating shaft 331 of the arc-shaped rack 330 can be adjusted to achieve a two-stage amplification of the stroke of the arc-shaped rack 330, which can greatly increase the number of rotations of the generator and maximize the power generation efficiency of the generator.

[0052] Reference Figure 1 、 Figure 3 、 Figure 5 In some embodiments, a spring 150 is provided between the sensor holder 420 having the second driving member 430 and the housing assembly 100. When the electronic scale is in use, an object to be weighed is placed on the panel 110, and the sensor holder 420 moves upward relative to the housing assembly 100 under the action of the gravity of the object to be weighed. The second driving member 430 on the sensor holder 420 cooperates with the first driving member 310 on the transmission rack to enable the power generation component 200 to generate electricity, and at the same time, the spring 150 is compressed or stretched. After the electronic scale is used, the object on the panel 110 is removed, and the sensor holder 420 is reset under the action of the spring 150, so that the sensor holder 420 can move up and down relative to the housing assembly 100 when the electronic scale is used again.

[0053] Reference Figure 6 、 Figure 7 In some embodiments, the housing assembly 100 is provided with a housing cavity 160, and the sensor seat 420 is accommodated in the housing cavity 160. The sensor seat 420 and the side wall of the housing cavity 160 are provided with a limiting structure, and the limiting structure is used to limit the sensor seat 420 so that the sensor seat 420 can move in the up and down directions in the housing cavity 160 and prevent the sensor seat 420 from detaching from the housing cavity 160.

[0054] Reference Figure 7 In some embodiments, the limiting structure includes multiple limiting ribs 161, multiple limiting notches 421, and at least two limiting buckles 162. The multiple limiting ribs 161 are spaced apart along the inner circumferential wall of the accommodating cavity 160, and the multiple limiting notches 421 are spaced apart along the circumference of the sensor holder 420. The limiting ribs 161 are inserted into corresponding limiting notches 421. The limiting ribs 161 also guide the vertical movement of the sensor holder 420. At least two limiting buckles 162 are spaced apart along the inner circumferential wall of the accommodating cavity 160. The limiting buckles 162 are adapted to abut against the side of the sensor holder 420 facing away from the bottom wall of the accommodating cavity 160 to prevent the sensor holder 420 from escaping from the accommodating cavity 160.

[0055] Reference Figure 7 The side wall of the accommodating cavity 160 is provided with an avoidance notch 163 , the second driving member 430 is passed through the avoidance notch 163 and cooperates with the first driving member 310 .

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
