The width of the end of the bent portion 322 after the C-shaped corner is inverted may be 0.2-0.6mm, and in order to ensure the maximum supporting width, the width of the supporting platform 111 on the middle frame 110 may be made larger than the width of the end of the bent portion 322, so as to ensure the maximum effective supporting width within the fitting tolerance range.
Referring to fig. 14, fig. 14 is a schematic partial structure view of the middle frame in fig. 9, in this embodiment, the height H of the supporting platform is in the range of 0.05-0.15mm, and may be, specifically, 0.05mm, 0.06mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, and the like. Considering that the screen limiting mode of the scheme utilizes the plane (the end face 3223 in fig. 12) in the side thickness direction of the display screen cover plate 320 as the supporting surface limiting, the limiting height of the supporting platform 111 on the middle frame 110 directly affects the appearance leakage gap, so that in order to ensure the appearance fineness (generally, the maximum value of the appearance gap is required to be less than 0.1mm), the scheme can design the supporting platform height to be about 0.06mm, and the scheme provides that the matching surface of the supporting platform 111 of the middle frame 110 can be formed by CNC machining, so that the machining consistency and the machining error minimization of the supporting platform 111 in the Z direction (the thickness direction of the electronic device) are ensured.
The electronic equipment in the embodiment of the application is based on the structure of a four-side curved display screen, wherein a support table is arranged on the local part of a middle frame, and the side surface of a cover plate of the display screen is utilized to realize the limit in the thickness direction; the supporting and matching surface of the display screen cover plate is provided as a horizontal plane, so that the limiting is convenient and accurate, and the middle frame and the supporting surface of the display screen cover plate can be processed through post CNC (computer numerical control) to ensure the processing precision; in addition, the middle frame is provided with the dispensing slot, so that the dispensing bonding surface comprises the end surface and the inner surface of the display screen cover plate, the longer dispensing width is ensured, and the bonding, the water resistance and the dust resistance are better; furthermore, through at display screen apron holding surface and display screen apron internal surface silk screen printing ink, play the effect that hides the pleasing to the eye of the complete machine of assurance of ugly on the one hand, on the other hand can make electronic equipment openly have profound and 3D feel, forms the no black limit effect of vision.
The above description is only a part of the embodiments of the present invention, and not intended to limit the scope of the present invention, and all equivalent devices or equivalent processes performed by the present invention through the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
