Problems solved by technology
[0003] Existing smartphones have canceled the traditional mobile phone buttons and switched to touch screen operation, but only a few buttons are reserved, such as: volume adjustment, power on and off, etc., which are usually set on the side of the mobile phone shell. As a support, there are certain requirements for its installation structure. Traditional mobile phones usually use plastic pillars or glue to fix the side buttons of the mobile phone on the inside of the shell. The structure is not strong enough and is prone to damage.

Embodiment
[0028] Example: A processing method for processing this key reinforcing sheet includes the following steps:
[0029] S1, dividing the symmetrical two sides of the inner curved top groove 5 into ten etching processing areas according to the horizontal length direction;
[0030] S2, starting etching from two adjacent etching processing areas at the center of the top groove 5 of the inner arc surface;
[0031] After the etching processes in S3 and S2 are completed, the two adjacent etching processing areas are exposed for further etching operations, and the amount of etching solution is increased by 2%;
[0032] S4, continuously exposing the two outer etching processing areas and performing etching processing, wherein the amount of etching solution is increased by 2% on the basis of the amount of etching solution in S2, and then repeating this step for eight times along the arrangement of the etching processing areas in sequence to obtain a stepped rough inner arc top groove 5;

The invention discloses a button reinforcement sheet and a processing method thereof, comprising a main body copper sheet, characterized in that: the main body copper sheet is provided with two sets of support parts, and the support parts include a left support leg, a right support leg and a The connecting bridge between the right leg and the right leg, the left leg and the right leg are arranged below the main body copper sheet, the connecting bridge is arranged above the main body copper sheet, the left leg and the right leg pass through the main body copper sheet and are connected to the connecting bridge On both sides of the main body, an inner arc top groove is opened on the main body copper sheet, and the connecting bridge includes an arc-shaped connecting bridge embedded in the inner arc top groove, and through holes are opened on both sides of the inner arc top groove , the left leg and the right leg are respectively interspersed in the through holes on both sides, the left leg, the right leg and the connecting bridge are integrally cast, the advantage of the present invention is that it provides a key that can be firmly installed and is not easily deformed when pressed for a long time Reinforcement sheet.
Description
Technical field [0001] The invention relates to a metal workpiece, in particular to a key reinforcing sheet and a processing method thereof. technical background [0002] With the continuous development of electronic technology, the types and varieties of electronic products are becoming more and more abundant, and electronic products are gradually becoming thinner and thinner. As the volume of electronic products becomes smaller and thinner, new technical requirements are put forward for the shell and internal fittings of electronic products, that is, the strength problem. When the volume is small, the mechanical strength of some parts or specific positions will inevitably be affected, so it is necessary to adopt certain technologies to reinforce them. [0003] The existing smart phones have cancelled the traditional mobile phone keys, and changed to touch screen operation, while only a few keys, such as volume adjustment, on-off and so on, are reserved, which are usually arrang...
