Apple Patents Hinge Mechanism Designed to Prevent Excessive Rotation
Details of Apple’s new hinge design can be found in a document revealed on the US Patent and Trademark Office (USPTO) web site (via GSMArena). It describes an digital gadget that’s geared up with a hinge construction that bends round an axis, together with a versatile show that’s divided into two sections (Fig. 4).
The firm’s patent contains figures that present a hinge mechanism that options a number of hyperlinks which can be designed to rotate relative to one another (Fig. 21), to allow the folding and unfolding of the gadget. It can be geared up with a friction clutch mechanism that options interlocked ‘fingers’ and crescent-shaped slots that may management the motion of the aforementioned hyperlinks, whereas guaranteeing it isn’t prolonged past a selected restrict.
According to Apple, the brand new hinge mechanism additionally options two units of rotational synchronisation gears (Fig. 10), and it seems that they’re designed to supply fine-grained management over how the gadget is unfolded. The doc accommodates drawings that present the odd and even hyperlinks working collectively to realize this performance.
A ‘counterbalance mechanism’ has additionally been described by the corporate, which might comprise a spring, a pad, and a curler (Fig. 17). These parts would provide a folding torque that may work towards the torque exerted when the show is unfolded, offering a managed (and clean) motion throughout this course of.
Like different mechanical parts, the hinge mechanism would even be affected by put on and tear over time. In order to minimise the influence, the hyperlinks within the hinge are proven to characteristic curved surfaces, that may additionally allow smoother rotation. The functioning of the mechanism is seen from Fig. 22 to Fig. 25.
The firm additionally describes different parts that might be a part of the foldable gadget — these embrace a digicam that’s lined when the display is folded, in addition to a two-dimensional array of haptic units to supply suggestions. It would additionally help audio playback through audio system which can be situated on the corners of the versatile show.
Apple’s newest patent for a hinge mechanism will not be indicative of the corporate’s plans to launch a foldable telephone. Given the corporate’s tendency to maintain its plans below wraps till it launches new units, we must await an official announcement from the agency on when it would launch its first foldable gadget.
