Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0034] Referring to Figures 1 to 6 , an electronic scale with button 200 - type self - power generation proposed in an embodiment of the present utility model includes a housing assembly 100, a button 200 power generation assembly 300, and a transmission rack 400.

[0035] A panel 130 is provided on the housing assembly 100. The panel 130 is used to place the object to be weighed. And a display screen can be provided on the panel 130, and the weight of the weighed object can be displayed on the display screen.

[0036] The housing assembly 100 includes a bottom cover 110 and a face cover 110. The bottom cover 110 and the face cover 110 are assembled together, and an accommodation space 140 is formed between the bottom cover 110 and the face cover 110. The power generation assembly 300 is arranged in the accommodation space 140 of the housing assembly 100. The power generation assembly 300 includes a power generation gear set 310 and a generator. The power generation gear set 310 can drive the generator to rotate at a high speed, so as to generate electricity for the generator. A sensor assembly 500 and a control board 600 are arranged in the accommodation space 140 of the housing assembly 100, and the sensor assembly 500 and the control board 600 are electrically connected. The electric energy generated by the generator is used for the sensor assembly 500 and the control board 600.

[0037] The button 200 is arranged on the housing assembly 100. The button 200 can move in the up and down direction. One end of the button 200 is located inside the housing assembly 100, and the other end extends outside the housing assembly 100. A first driving member 210 is provided on the button 200. The transmission rack 400 is arranged inside the housing assembly 100. The transmission rack 400 is arranged in the horizontal direction and can move inside the housing assembly 100. In other words, the transmission rack 400 can move or rotate in the horizontal plane. The transmission rack 400 is meshed and driven with the input gear of the power generation gear set 310.

[0038] A second driving member 420 is provided on the transmission rack 400. At least one of the first driving member 210 and the second driving member 420 is provided with an inclined surface. When the button 200 moves in the up and down direction, the first driving member 210 can drive the second driving member 420 through the inclined surface, so that the second driving member 420 drives the transmission rack 400 to rotate or move in the horizontal plane. Since the transmission rack 400 is meshed and driven with the input gear of the power generation gear set 310, when the transmission rack 400 moves or rotates in the horizontal plane, it can drive the power generation gear set 310 to rotate, thereby driving the generator to generate electricity.

[0039] With the above structure of the present utility model, the transmission rack 400 is arranged in the horizontal direction, and the up and down movement of the button 200 is converted into the movement of the transmission rack 400 in the horizontal plane. Therefore, the generator assembly can be thinned, and the weighing body can also be made thinner, which not only saves materials and costs, but also reduces the storage space during storage, and has a beautiful appearance.

[0040] Refer to Figure 1 、 Figure 2 、 Figure 3 In some embodiments, the first driving member 210 is provided with a first inclined surface 211, and the second driving member 420 is provided with a second inclined surface 421. The second inclined surface 421 is used to abut against the first inclined surface 211. Through the cooperation of the first inclined surface 211 and the second inclined surface 421, the contact area between the first driving member 210 and the second driving member 420 can be increased, and the assembly stability of the first driving member 210 and the second driving member 420 can be improved.

[0041] It can be understood that in some embodiments, the first inclined surface 211 is provided on the first driving member 210, and the second driving member 420 is arranged in a cylindrical shape or a semi-cylindrical shape, so that the first driving member 210 and the second driving member 420 are in line contact to reduce the frictional resistance between the first driving member 210 and the second driving member 420. Or, in some embodiments, the second inclined surface 421 is provided on the second driving member 420, and the first driving member 210 is arranged in a cylindrical shape or a semi-cylindrical shape, so that the first driving member 210 and the second driving member 420 are in line contact to reduce the frictional resistance between the first driving member 210 and the second driving member 420.

[0042] It can be understood that, in some embodiments, one of the driving members is provided with an inclined surface, and the other driving member is provided with a roller. The roller can roll on the inclined surface, so as to form a rolling friction between the first driving member 210 and the second driving member 420, further reducing the frictional resistance between the first driving member 210 and the second driving member 420.

[0043] It can be understood that the slope and length of the second inclined surface 421 can be adjusted. By adjusting the slope and length of the second inclined surface 421 on the second driving member 420, the stroke of the transmission rack 400 can be adjusted, which can increase the number of rotation turns of the generator, and thus improve the efficiency of the generator.

[0044] Refer to Figures 1 to 5 , in some embodiments, the transmission rack 400 is an arc-shaped rack, and the arc-shaped rack is arranged in the housing assembly 100 and can rotate around the rotating shaft 410 in the horizontal plane within the housing assembly 100. Thus, by adopting the transmission mode of inclined surface cooperation, the up-and-down movement direction of the sensor seat is converted into the rotation of the arc-shaped rack in the horizontal plane, so that the generator assembly can be thinned, which is beneficial to reducing the thickness of the housing assembly 100, and further making the electronic scale thinner.

[0045] Refer to Figure 1 , Figure 2 , in some embodiments, a first return spring 430 is provided between the arc-shaped rack and the housing assembly 100. One end of the first return spring 430 is connected to the housing assembly 100, and the other end of the first return spring 430 is connected to one side of the arc-shaped rack. After the key 200 is reset, the arc-shaped rack is reset under the action of the first return spring 430, so as to drive the power generation assembly 300 to generate electricity when the key 200 is pressed again.

[0046] It can be understood that by changing the position of the rotating shaft 410 of the arc-shaped rack, the amplification of the rotation angle can be realized, the stroke of the arc-shaped rack can be increased, and thus the number of rotation turns of the generator can be increased, and the efficiency of the generator can be improved.

[0047] It can be understood that when a greater improvement in the power generation efficiency of the generator is required, the slope and length of the inclined surface and the position of the rotating shaft 410 of the arc-shaped rack can be adjusted, so that the stroke of the arc-shaped rack can be amplified in two stages, which can greatly increase the number of rotation turns of the generator and maximize the power generation efficiency of the generator.

[0048] It can be understood that, in some embodiments, the transmission rack 400 can also be set as a linear rack, and the linear rack is movably arranged in the housing assembly 100 along the horizontal direction, which will not be elaborated here.

[0049] Refer to Figure 1 ,Figure 6 , in some embodiments, a second return spring 220 is provided between the key 200 and the housing assembly 100. One end of the second return spring 220 abuts against the housing assembly 100, and the other end abuts against the key 200. When the key 200 is pressed, while the first driving member 210 on the key 200 drives the rack to move, the key 200 compresses the second return spring 220; when the key 200 is released, the key 200 is reset under the action of the second return spring 220, so as to facilitate driving the power generation assembly 300 to generate electricity by using the arc rack when the key 200 is pressed again.

[0050] Refer to Figure 6 , in some embodiments, a cavity 212 with an open end is provided in the key 200. One end of the second return spring 220 is arranged in the cavity 212, and one end of the second return spring 220 abuts against the bottom wall of the cavity 212, and the other end abuts against the housing assembly 100. The cavity 212 can limit the second return spring 220 to extend or compress only in the up and down direction, so as to prevent the second return spring 220 from running off, and improve the stability of the electronic scale during use.

[0051] Refer to Figure 1 , in some embodiments, a panel 130 is provided on the housing assembly 100, and an avoidance hole 131 is provided on the panel 130. The key 200 passes through the avoidance hole 131.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
