Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustrati...

The invention discloses a protective cover for a fixed-point touch screen electronic device, comprising a casing and a micro-electricity generating component, wherein the micro-electricity generatingcomponent comprises a fixed power generating strip, a flexible touch screen bar, a moving power generating strip and a fixed point bar; the fixed power generating strip is fixed on the casing, the flexible touch screen bar is slidably connected to the fixed power generating strip by the moving power generating strip, the moving power generating strip is forced to move along the fixed power generating strip to generate electricity by friction, the binding abilities of the moving power generating strip and the flexible touch screen bar to electrons are both greater than the fixed power generating strip so that the moving power generating strip and the flexible touch screen bar are charged, the flexible touch screen bar is further provided with a plurality of touch screen pins on one side facing the casing; the fixed point bar is slidably connected to one side of the flexible touch screen bar back on to the touch screen pins, the fixed point bar is forced to slide along the flexible touchscreen bar, and the fixed point bar may resist the flexible touch screen bar when being forced to move toward the casing. The invention enables the use of a capacitive touch screen handset and accurate point fixing in the event of a finger injury and being wrapped by a bandage or with gloves.
Description
【Technical field】 [0001] The invention relates to the field of auxiliary tools for communication equipment, in particular to a protective case for an electronic device with a fixed-point touch screen. 【Background technique】 [0002] A touch screen mobile phone is a type of mobile phone that applies touch screen technology to the mobile phone screen. In the process of using a touch-screen mobile phone, it is necessary to click on the screen with a finger to achieve the effect of using the function of the mobile phone. Among the many types of touch-screen mobile phones, capacitive touch screens are widely used in touch-screen mobile phones. The principle is to plate long and narrow electrodes on the four sides of the touch screen to form a low-voltage AC electric field in the conductor. When the user touches the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electr...
