The beneficial effects of the utility model:

The electronic scale of the utility model adds a multi-stage gear set and a generator, and uses a concealable display screen module to drive the multi-stage gear set to rotate when the scale body is pulled outward or pushed inward. After the four-stage acceleration of the multi-stage gear set , the multi-stage gear set drives the generator to run at high speed to generate electricity, and the kinetic energy is converted into electric energy and stored in the energy storage module through the rectification and voltage stabilization circuit. This electronic scale does not need the supply of an external energy storage module, which is energy-saving and environmentally friendly. Affected by the environment, it is simple to operate and easy to use, and at the same time has the small size and aesthetics brought by the built-in display screen.

detailed description

As shown in Figure 1, it is a self-generating electronic scale with a hidden display of the present invention, which includes a scale body 1 belonging to the basic components and a main control board 3 arranged in the inner chamber of the scale 2, and the main control board 3 respectively connected with the main control board. 3. The sensor module 4, the display module 5, the energy storage module 6, and the button part 11 are electrically connected.

As shown in Figure 2, the scale body 1 can be an integral shell. The scale body 1 of this embodiment is composed of a cover 11 and a bottom shell 12. The cover 11 is provided with a tempered glass 14, which is used to protect the scale body. And play a supporting role, the number of sensors in the sensor module 4, the matching AD conversion circuit, the types of the display module 5 and the energy storage module 6 (such as rechargeable batteries, capacitive elements, etc.) can be replaced arbitrarily in the conventional selection, because The above-mentioned components belong to existing solutions, so details are not repeated here.

In order to solve the power generation and power supply problem that the display screen can be hidden and the electronic scale is not bound by the environment, this technical solution designs a chute 7 extending from the scale body cavity 2 to the outside of the scale body 1 under the framework of the above-mentioned basic components, and is arranged in the The multi-stage gear set 8, the generator 9, and the rectifying and stabilizing circuit 10 in the inner chamber of the scale 2, as shown in Figure 3, the display screen module 5 is arranged in the chute 7 for it to hide or leak in the inner chamber of the scale 2.
