Problems solved by technology

However, any stack-up of manufacturing tolerances for locking components can affect the flatness of the electronics in the deployed position, and movement between several pivot points must be synchronized in order to provide adequate locking force

Embodiment Construction

[0040] Figure 8 and Figure 9 An electronic device 17 is shown, comprising a first frame part 4, a second frame part 5, a display 2 connected to at least one of the first frame part 4 and the second frame part 5, and a hinge assembly 1, the hinge assembly 1. The first frame part 4 and the second frame part 5 are interconnected so that the first frame part 4 and the second frame part 5 can be pivoted relative to each other between the unfolded position P1 and the first folded end position P2a. In one embodiment, the hinge assembly 1 is also movable between the unfolded position P1 and the second folded end position P2b. When the hinge assembly 1 is folded, the electronic device 17 is also folded from the unfolded position to the folded end position. The electronic device 17 may also include a rear cover disposed opposite the display 2 .

[0041] like Figure 1c and Figure 1d As shown, when in the unfolded position P1, the first frame portion 4 and the second frame portio...

Abstract

A hinge assembly (1) for an electronic device (17), the hinge assembly (1) being movable between a deployed position (P1) and a folded end position (P2), the hinge assembly (1) comprising a row of interconnected and adjoining hinge blades (9) and at least one linear actuator (7). The hinge blades (9) are aligned on a common plane when the hinge assembly (1) is in the deployed position (P1) and each hinge blade (9) rotates relative to an adjacent hinge blade (9) about a hinge assembly axis of rotation (A1) when the hinge assembly (1) is moved to the folded end position (P2). The linear actuator (7) comprises a rotating shaft (12) and a linear driving device (13). A first end of the linear drive (13) is interconnected with the rotating shaft (12), and an opposite second end of the linear drive (13) is connected to a hinge blade (9). An actuator axis (A2) extends between the first end and the second end and is perpendicular to the hinge assembly axis of rotation (A1), and actuation of the linear actuator (7) along the actuator axis (A2) causes each hinge blade (9) to rotate about the hinge assembly axis of rotation (A1) relative to an adjacent hinge blade (9). The linear actuator (7) further comprises a locking device (3) for locking the hinge assembly (1) in at least one of the unfolded position (P1) and the folded end position (P2), the locking device (3) comprising a cam element (6) that interlocks with a cam portion (10) located on the rotating shaft (12). Due to the fact that the locking device is arranged, the various manufacturing tolerances are not stacked, and therefore good flatness is provided in the unfolding position.

Description

technical field [0001] The present invention relates to a hinge assembly for an electronic device that is movable between an unfolded position and a folded end position. Background technique [0002] The size of electronic devices such as tablets and mobile phones is an important consideration when designing electronic devices. Users often demand that the external dimensions of the device be as small as possible, while still providing the largest possible display. [0003] For example, this problem can be solved by a foldable electronic device comprising one or more supports, eg interconnected by hinges, covered by a display. The one or more supports and the display can be folded together to provide the smallest possible electronic device and unfolded to provide the largest possible display. [0004] Preferably, the hinges are lockable in the unfolded and folded positions. However, any stacking of locking assembly manufacturing tolerances can affect the flatness of the el...
