Downward pressing plate, blind key attaching device, blind key component and blind key attaching assembly

Abstract

The embodiment of the invention provides a downward pressing plate which is used in combination with a blind key attaching device to fix a blind key to a screen of a mobile terminal, wherein the downward pressing plate is provided with a plate body main body, a containing part protruding relative to the plate body main body is arranged on the first side of the plate body main body, the containingpart is provided with an opening, the blind key is embedded into the containing part, and a first end, used for being fixed to a screen, of the blind key protrudes out of the opening. In addition, theblind key attaching device provided by the embodiment of the invention is provided with a right-angle clamping groove defined by an upper end panel and a lower end panel, and the right-angle clampinggroove is used for containing one corner of a mobile terminal. A containing cavity is formed in the upper end panel, the containing cavity is provided with an upper end opening and a lower end opening, the size of the upper end opening is matched with that of a plate body main body of the downward pressing plate, and the lower end opening is communicated with the right-angle clamping groove and allows the containing part of the downward pressing plate to penetrate through; a groove is formed in the side wall, facing the interior of the right-angle clamping groove, of the upper end panel, andthe blind key attached to a mobile terminal screen is allowed to penetrate through the groove.

Description

technical field [0001] The embodiment of this specification relates to the field of terminal technology, specifically, to a lower pressing plate and a blind key affixing device that can be used in combination, and the corresponding method of use, and a blind key member that can be used in combination, and a blind key affixing device, and the corresponding usage method. Background technique [0002] At present, visually impaired users (such as blind users) usually use screen reading software to operate mobile phones, and the screen reading software provides voice feedback after touching the screen with a finger. However, there are still many problems in this interaction method, such as lack of tactile feedback, visually impaired users often need to access a large number of unnecessary elements, low error tolerance rate, high cost and frequent error correction. [0003] Therefore, there is an urgent need for a more reasonable and reliable solution that can improve the user ex...
