[0058] Like the first embodiment, the second embodiment of the device for obtaining energy is likewise arranged in the housing 100 ( Figure 4 ). According to this embodiment, the actuation element 110 and the gear element 135 implement a rack drive. This means that the gear element 135 arranged in the middle of the housing 100 rotates about its bearing axis during the linear displacement of the actuating element 110 . For this purpose, the actuating element 110 has a toothed rack region 117 which is coupled to the second additional gear wheel.

[0059] The actuating element 110 has two parallel-running rods 113 which are connected to each other at an end 114 of the actuating element 110 facing away from the housing 100 . The actuation element 110 is guided in the direction from the first side wall 101 to the second side wall 102 of the housing 100 by means of two bore holes 118 arranged in the first side wall 101 of the housing 100 . Only the (currently the left) lever 113...

Abstract

The invention relates to a device for harvesting energy for use on a door or window, having: a movable actuation element that can be coupled to the door or the window; at least one gear wheel mechanically coupled to the actuation element, each gear wheel having at least one permanent magnet or being coupled to a permanent magnet; and at least one coil, the device having, for each gear wheel, at least one coil associated therewith, and the actuation element and the at least one gear wheel being coupled such that, when the actuation element is moved, the at least one gear wheel is rotated about its respective axis, and when said at least one gear wheel is rotated about its respective axis, a voltage is induced in the at least one coil and energy is harvested as a result. The invention also relates to a sensor for detecting an opening or closing operation of a window or door.

Description

technical field [0001] The present disclosure relates to a device for harvesting energy for a door or window, a sensor for detecting the opening or closing process of a window or door, and a sensor. Background technique [0002] Energy Harvesting, which literally translates to energy harvesting, is known in the prior art. This is understood to mean that, for low power mobile devices, a small amount of power is obtained from sources such as ambient temperature, vibrations or air flow. The structures used for this purpose, known as energy harvesters or also as nanogenerators, avoid, in wireless technology, limitations due to wired current supplies or batteries. Energy harvesting is of great importance for the energy supply of tiny devices in the digital world, and considering the Internet of Things, attempts are being made to make small sensors present in said "things" independent of external current supplies. [0003] For example, energy harvesting can be accomplished by me...
