Buttons and Electronics

technical field

The present invention relates to a button and an electronic device, and in particular, the present invention relates to a button capable of preventing a user from accidentally touching it and an electronic device including the button.

Background technique

With the advancement of technology and the increase of human needs, all kinds of electronic devices are flooding the lives of modern people, from simple flashlights and music players to more complex mobile phones, digital cameras, computers, etc., each playing their own roles. with different roles.

For the convenience of use, most of these electronic devices, especially portable electronic devices, can choose to be powered by an external power source (namely mains power) or a built-in battery. Moreover, most of the electronic devices are equipped with a switch, so that the user can start the electronic device to receive the power from the external power supply or the built-in battery and start to operate when needed.

In the prior art, most of the switches of the electronic device are toggle type or push type. Please refer to FIG. 1, which is a cross-sectional view of a flashlight according to the prior art. As shown in the figure, the flashlight 9 in the prior art mainly includes an upper cover 90 , a body 91 , a bulb 92 , a light cup 93 , a circuit board 94 , a battery 95 , a button 96 and a spring 97 .

The upper cover 90 and the main body 91 are usually detachably connected together. In addition, the light bulb 92 and the light cup 93 are arranged on the upper cover 90 , wherein the light cup 93 can reflect the light emitted by the light bulb 92 , so that the light is emitted out of the flashlight 9 substantially in parallel. The circuit board 94 is generally disposed between the upper cover 90 and the body 91 , and the circuit board 94 is electrically connected to the bulb 92 . The battery 95 is accommodated in the body 91 and electrically connected to the circuit board 94 for providing the power required by the light bulb 92 to emit light. The button 96 is connected to the spring 97 and is disposed at the rear end of the body 91 . A switch (not shown in the figure) is arranged inside the button 96, one end of the switch is connected to the negative pole of the battery 95 by a spring 97, and the other end of the switch is connected to the bulb 92 by the circuit board 94, and then connected to the positive pole of the battery 95 by the circuit board 94.

When the user presses the button 96 , the switch inside the button 96 forms a path, so that the battery 95 can supply power to the light bulb 92 . Further, when the user does not use the flashlight 9 , as long as the button 96 is pressed again, the switch inside the button 96 can be disconnected, so that the battery 95 cannot supply power to the bulb 92 .

However, when the user carries the aforementioned flashlight 9 in a handbag, pocket, etc., the battery 95 will often supply power to the bulb 92 due to touching the button 96 by mistake. Such a situation will cause the power loss of the battery 95. In addition to the waste of power resources, it may also cause the user to find that the flashlight 9 is out of power and cannot be used when it needs to use it. Such a situation also often occurs in electronic devices with toggle switches.
