背景技术Background technique

目前手机的前盖多数将玻璃盖板粘接于手机的边框上，通常在边框的内侧设置台阶，利用台阶承载玻璃盖板的边缘，同时在台阶和玻璃盖板之间设置粘胶，然而采用此种结构容易导致玻璃盖板压合于边框的台阶时，边框外表面与玻璃盖板之间容易有接缝，此时，若在手机前盖上观察，容易观看到台阶与玻璃盖板的粘胶，外观装饰效果不佳；同时，由于粘胶时容易造成粘胶滴落至边框以及显示屏之间，从而导致由溢胶引起手机的组装结构不佳，使得手机的使用性能不佳，故而不利于用户体验。At present, most of the front covers of mobile phones glue the glass cover to the frame of the mobile phone, and usually set steps on the inner side of the frame, use the steps to carry the edge of the glass cover, and set glue between the steps and the glass cover. This structure tends to cause a seam between the outer surface of the frame and the glass cover when the glass cover is pressed onto the steps of the frame. At this time, if one observes on the front cover of the mobile phone, it is easy to see the gap between the steps and the glass cover. Adhesive glue, the appearance decoration effect is not good; at the same time, because the glue is easy to cause the glue to drip between the frame and the display screen, resulting in poor assembly structure of the mobile phone caused by overflow glue, making the mobile phone's use performance poor. Therefore, it is not conducive to user experience.
