Description

按键防水结构和移动终端Key waterproof structure and mobile terminal 技术领域Technical field
本文涉及但不限于通信设备技术领域，尤指一种按键防水结构和一种移动终端。This document relates to, but is not limited to, the field of communication device technology, and in particular to a key waterproof structure and a mobile terminal.
背景技术Background technique
智能手机，如图1所示，其按键100的防水结构还是功能机键盘装配的防水结构，应用在智能手机上，尺寸难以匹配，按此设计的产品外观以及结构可靠性都有缺陷。The smart phone, as shown in Figure 1, the waterproof structure of the button 100 is also a waterproof structure of the function machine keyboard assembly, is applied to the smart phone, the size is difficult to match, and the product appearance and structural reliability according to the design are defective.
如图1所示，智能手机正面有显示屏200，显示屏200的显示区到上下边缘距离是不同的，显示区到下边缘之间的长边占用区域301因需布置显示屏200的器件和出线，会远大于显示区到上边缘之间的短边占用区域302。As shown in FIG. 1 , the front surface of the smart phone has a display screen 200. The display area of the display screen 200 has a different distance from the upper and lower edges, and the long-side occupied area 301 between the display area and the lower edge is required to arrange the device of the display screen 200 and The outgoing line will be much larger than the short side occupied area 302 between the display area and the upper edge.
如果显示屏200如图1所示正置，按键100位于显示屏200下方，按键100的防水结构及按键100都需要错开显示屏200，如图2，显示屏200下方是前壳，前壳到按键100(相当于本申请中的按键本体)之间需要安装按键软胶400进行防水(按键100下方具有按键软胶400形成的防水密封区域)，这就造成整机下部的非显示区域300就会变的特别长(主要是防水密封区域尺寸较大，造成显示屏200的下边缘到前壳的下边缘的长度增加)，整机上部和下部的非显示区域300的比例就会很不协调。If the display screen 200 is placed upright as shown in FIG. 1 and the button 100 is located below the display screen 200, the waterproof structure of the button 100 and the button 100 need to be staggered by the display screen 200. As shown in FIG. 2, the front cover of the display panel 200 is the front case, and the front case is The button 100 (corresponding to the button body in the present application) needs to be installed with the button soft rubber 400 for waterproofing (the waterproof sealing region formed by the button soft rubber 400 under the button 100), which causes the non-display area 300 of the lower portion of the whole machine to be It will become extremely long (mainly because the size of the waterproof sealing area is large, causing the length of the lower edge of the display screen 200 to the lower edge of the front case to increase), and the ratio of the upper and lower non-display areas 300 of the whole machine will be very uncoordinated. .
为了防止整机上部和下部的非显示区域300的长度相差太大，如图3所示，一般会将显示屏200倒置，按键100配合显示屏200的短边占用区域，虽然也会导致整机长度增加，但整机上部和下部的非显示区域300对称，相对显示屏正置方案，整机更美观。In order to prevent the difference between the lengths of the upper and lower non-display areas 300 of the whole machine from being too large, as shown in FIG. 3, the display screen 200 is generally inverted, and the button 100 cooperates with the short-side occupied area of the display screen 200, although the whole machine is also caused. The length is increased, but the non-display area 300 of the upper part and the lower part of the whole machine is symmetrical, and the whole machine is more beautiful than the display screen.
然而，显示屏200倒置，效果如图3所示，虽然解决了上部非显示区域300小，下部非显示区域300大的问题，其实质只是显示区的上下移动，并没有缩小整机正面的尺寸，且显示屏200倒置还会导致显示屏200的器件与 主板的器件重叠，增加整机的发热量，所以显示屏200倒置不是最优设计，只是做了视觉上的处理，正面防水按键100占用空间并没有改变。However, the display screen 200 is inverted, and the effect is as shown in FIG. 3. Although the problem that the upper non-display area 300 is small and the lower non-display area 300 is large is solved, the essence is only the up and down movement of the display area, and the size of the front surface of the whole machine is not reduced. And the display panel 200 is inverted, which also causes the device of the display screen 200 to overlap with the device of the main board, thereby increasing the heat generation of the whole machine. Therefore, the display 200 is not inverted, but the visual processing is performed, and the front waterproof button 100 is occupied. The space has not changed.

传统的密封通常是将一个硅胶件做大(如图2所示的按键软胶400)，需要远大于按键100的直径，即密封结构要做在按键100内侧的结构件空间内，通过按键软胶400的挤压或按键软胶400用防水背胶正反粘贴到按键100和按键开关之间来防水，这种结构需要做在按键100之外，受按键100大小的限制。而本申请的密封圈3组成的防水结构可以做的比触发部小，不会因设置密封圈3而需要增加移动终端下部非显示区域的空间(即：不会因设置密封圈3而需要增加触摸显示单元下边缘到壳体1下边缘的长度(a处上下方向的长度)，如图7所示，触摸显示单元下边缘到壳体1下边缘位于长边占用区域62的下方，长边占用区域62的下边缘即触摸显示单元的下边缘)。The traditional seal is usually to make a silicone piece larger (such as the button soft rubber 400 shown in Figure 2), which needs to be much larger than the diameter of the button 100, that is, the sealing structure should be in the structure space inside the button 100, through the button soft The extrusion or soft rubber 400 of the glue 400 is waterproofed with the waterproof adhesive back and forth between the button 100 and the key switch.
