Problems solved by technology

[0004] Due to the functional limitation of the above-mentioned existing pivots, and in response to the recent demand for large-angle flipping or folding operations, it is becoming more and more popular to install two pivots that do not belong to the same operating axis between the upper cover and the base of the electronic equipment. , however, the preset dual spindles of the multiple pivots cannot control the coordination between them when they rotate, so that the degree of freedom, accuracy and smoothness of the rotation process of the entire electronic device cannot be controlled. Properly, the above-mentioned light-weight requirements cannot be effectively provided

Embodiment Construction

[0028] The novelty and other characteristics of the present invention will become clearer with the detailed description of the preferred embodiments in the accompanying drawings.

[0029] Please refer to Figure 8 and Figure 9 and Figure 12 to Figure 14 As shown, the present invention has two corresponding first folding parts 81 and second folding parts 82, and a multi-section rotating shaft structure 1 with both ends simultaneously retractable is installed between the two corresponding folding parts; The multi-section rotating shaft structure 1 can be implemented as Figure 1 to Figure 3 As shown, at least one active joint group 10 and follower joint group 20 (refer to image 3 ) are merged together, and cooperate with a plurality of shaft pins to form a multi-section shaft structure with both ends retracted synchronously.

[0030] In order to facilitate the description of the connection relationship between components, in the following related descriptions, such as f...

Abstract

A synchronous unfolding and folding apparatus comprises two corresponding folding members and a multi-joint rotating shaft structure arranged between the two corresponding folding members, two ends of the multi-joint rotating shaft structure synchronously unfold, the multi-joint rotating shaft structure can be formed by an active joint group and a following joint group, the active joint group is provided with two joint sheets facing each other and an intermediate linking sheet connected between the two joint sheets, and two ends of the active joint group are combined with the two corresponding folding members respectively; and anyone of the joint sheets facing each other of the active joint group can freely rotate around a plurality of rotating centers, so smooth synchronous unfolding and folding of two ends can be formed in order to realize accurate corresponding unfolding and folding operation effects.

Description

technical field [0001] The present invention relates to a synchronous unfolding and folding device, especially an electronic device with two corresponding and accurate folding parts. Increasing its rotational freedom allows the two ends of the electronic device to turn open or close more smoothly. Background technique [0002] Taking electronic devices with relatively foldable parts (such as foldable displays, handheld game consoles, portable electronic secretaries, mobile phones, e-books, electronic utensils, etc.) that are commonly used nowadays as an example, they usually consist of a base and foldable parts. The base and the upper cover are connected together by a pivot device, and the upper cover can use the pivot device as the action axis to expand and close between the two folding parts. The importance of this type of pivot lies in that besides being the axis of action of the electronic device itself, the structural design must take into account whether the unfolding...
