Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the first embodiment of the present invention provides an electronic device 100 with a drop protection function, which includes an electronic device body 110 and a sensing device 120 .

The device body 110 may specifically be a main body of an electronic device such as a notebook computer, a portable player, a digital camera, and a mobile phone. The device body 110 includes a controller 111, a housing 112, a keyboard 113, a screen 114, and internal circuits (not shown) that control various functions of the electronic device. The controller 111 and the internal circuit are housed in the housing 112 to protect the controller 111 and the internal circuit. The housing 112 can be cylindrical, polygonal prismatic, cuboid or other shape. In this embodiment, the housing 112 has a rectangular parallelepiped shape, and has a third side surface 1121, a fourth side surface 1122 opposite to the third side surface 1121, a working surface 1123, a bearing surface 1124 opposite to the working surface 1123, and a first side surface 1125. A second side 1126 opposite the first side 1125. The area of the working surface 1123 and the bearing surface 1124 is larger than the area of the first side surface 1125 and the second side surface 1126. The areas of the first side surface 1125 and the second side surface 1126 are larger than the areas of the third side surface 1121 and the fourth side surface 1122. The keyboard 113 and the screen 114 are exposed from the work surface 1123 of the housing 112. The keyboard 113 and the screen 114 are connected to the controller 111 by internal circuits. The command is input through the keyboard 113 and transmitted to the controller via the internal circuit, so that the controller realizes the function realized by the data input from the keyboard 113 from the screen 114.

The sensing device 120 is connected to the controller 111 for transmitting the sensed signal to the controller 111 to determine the state in which the electronic device 100 is located. The sensing device 120 is disposed on an outer surface of the housing 112 and includes a pressure sensor 121 and a touch sensor 122. The pressure sensor 121 is configured to sense whether it receives the pressure and transmit the sensing result to the controller 111, thereby causing the controller 111 to determine that the electronic device 100 is in the placed state. Or non-placed state. Specifically, when the pressure sensor 121 senses the pressure, the controller 111 determines that the electronic device 100 is in the placed state, and when the pressure sensor 121 does not sense the pressure, determines that the 100 is in the non-placed state. The touch sensor 122 is configured to sense whether the touch is touched, and the sensing result is transmitted to the controller 111, so that the controller 111 further determines that the electronic device 100 is in the holding state when determining that the electronic device 100 is in the non-placed state. Or fall down. When the touch sensor 122 senses that it is touched, the controller 111 determines that the electronic device 100 is in the grip state, and when the touch sensor 122 does not sense the touch, the controller 111 determines that the electronic device 100 is in the grip state. The state is dropped so that the controller 111 triggers the internal circuit so that 100 is in a protected state. For example, the electronic device 100 is caused to change from the power-on state to the power-off state or stop the program that the electronic device is performing, etc., to minimize damage to the electronic device 100 caused by the drop impact.

The number of the pressure sensor 121 and the touch sensor 122 can be set according to the shape of the housing 112 of the electronic device 100. In this embodiment, the sensing device 120 includes four pressure sensors 121 and three touch sensors 122. The four pressure sensors 121 are respectively disposed at a junction of the first side 1125 and the third side 1121, a junction of the third side 1121 and the second side 1126, a junction of the second side 1126 and the fourth side 1122, and a At the junction of the four sides 1122 and the first side 1125, the four pressure sensors 121 protrude from the working surface 1123 and the heights of the protrusions are equal. The four pressure sensors 121 protrude from the bearing surface 1124 and protrude. The height is also equal. When one or more of the four pressure sensors 121 sense the pressure, the controller 111 determines that the electronic device 100 is in the placed state at this time, and when none of the four pressure sensors 121 senses the pressure, the controller 111 It is determined that the electronic device 100 is in a non-placed state.

Three touch sensors 122 are respectively disposed on the first side 1125 and the second side 1126. Bearing surface 1124. The surfaces of the three touch sensors 122 are respectively level or slightly convex with the first side 1125, the second side 1126, and the carrying surface 1124. In this embodiment, the three touch sensors 122 are flush with the first side 1125, the second side 1126, and the carrying surface 1124, respectively. Each of the three touch sensors 122 extends in a direction from the third side surface 1121 toward the fourth side surface 1122. Of course, the number of touch sensors 122 may also be one, extending from the first side 1125 along the carrying surface 1124 to the second side 1126. When the electronic device 100 is in the non-placed state, one of the three touch sensors 122 or the plurality of touches senses the touch, the controller 111 determines that the electronic device 100 is in the grip state, when the touch sensor 122 does not When the touch is sensed, the controller 111 determines that the electronic device 100 is in a falling state, so that the protection state can be activated.

The length of the pressure sensor 121 disposed on the bearing surface 1124 protruding from the bearing surface 1124 should be greater than the length of the touch sensor 122 disposed on the bearing surface 1124 protruding from the bearing surface 1124. Therefore, when the electronic device 100 is placed on a tabletop or other place, whether the bearing surface 1124 is opposite to the desktop or the working surface 1123 is opposite to the desktop, the four pressure sensors 121 can be in contact with the desktop, and can be sensed from the desktop. The pressure, and thus the controller 111, can determine whether the electronic device 111 is in a placed state or a non-placed state. In this embodiment, the pressure sensor 121 may be a resistance strain pressure sensor or the like.
