Description

Shaft module of folding device

This creation relates to a hinge module, especially a folding electronic device that can be relatively unfolded or flipped.

Traditional folding electronic devices, such as the display and base of a notebook computer, are connected to the side of the display and the base through a single-mandrel hinge to form a pivot, so that the display can be flipped up or closed relative to the base. And because the flexible display device developed in recent years can be used with a foldable handheld electronic device, this kind of product has become one of the projects that various manufacturers are interested in investing in development. Among them, for example, a "foldable display device" patent case of the People's Republic of China Invention Patent No. CN106205385A (hereinafter referred to as the former case 1), whose structure includes a flexible display panel, a first support member, a second support member, and a first rotation Plate and second rotating plate. The flexible display panel includes first and second display areas and a curved display area located between the two display areas, so that the first and second support members are respectively under the two display areas and are respectively bent. The first and second portions of the display area extend below, so that the first and second rotating plates are configured to rotate about first and second axes parallel to each other, respectively, and extend toward the edges of the first and second support members, respectively; Thus, in the unfolded state of the foldable display device, two parts of the curved display area are respectively supported through the two support members, and the edges of the two support members are formed a predetermined distance below the curved display area. The rotating plates respectively support a part of the two supporting members, and the curved display area is bent with a predetermined curvature through the combination of the two rotating plates.

In the aforementioned first case 1, the two rotating plates / support members are each provided with one end portion in a pivot connection manner, because the rotation center is the pivot axis and the basis for the rotation of the two rotating plates / support members. In practice, the overall thickness is not easy to change, and the overall thickness is easily limited by the diameter of the components such as the shaft and pin used, so the overall thickness cannot be effectively reduced. Furthermore, the first and second hinge members of the first case belong to The "dual-axis hinge / hinge" has two centers of rotation, which makes it necessary to maintain a certain distance between the two axes for other two-axis structures, such as the tooth-like structure disclosed in the figure to generate relative motion. Therefore, in addition to making it difficult to reduce the overall size, it also makes it difficult for the flexible display device to have a small bending curvature after being folded in half.

In order to improve the shortcomings of the foregoing case 1, the applicant proposed an improvement plan, as shown in the patent case of the “Pivot Module of the Folding Device” of the People's Republic of China Utility Model No. CN109488681A (hereinafter referred to as the case 2), A first supporting member is connected to one end of a first rotating member, and the other end has a first semi-circular arc space for pivotally connecting a half-arc rotating shaft group. The first rotating member has a first rotating space and a first A limiting space for limiting one of the first support portion and the other end of the first swinging member respectively at the middle position of the first swinging member, the other end of the first swinging member pressing against a first elastic member, and the first swinging member One end is connected to the first rotating member; and the inside of the second rotating member has a second rotating space and a second limiting space for limiting a second support portion and a second swinging member respectively in the middle position of the second swinging member. At the other end, the other end of the second swinging member is pressed against a second elastic member, and one end of the second swinging member is connected to the second rotating member. Thereby, the first rotating member, the second rotating member, and the semi-circular arc shaft group can share the same rotation center when the whole flattening, effectively reducing the gap between the two bodies when closed, and reducing the overall volume to facilitate the design , And meet the market demand for thin overall size. And by adopting a structure similar to a seesaw, when the whole is bent, the accommodation space can be made to accommodate the curved intermediate portion of the flexible display device, and when the whole is flattened, it can support the flat shape of the flexible display device. Middle part.

However, the structure disclosed in the "Rotary Axis Module of the Folding Device" patent of the previous case 2, in the process of the two rotating parts flipped relative to each other and raised or closed, only relying on a plurality of spring pins can produce sufficient Torque is used to provide support, but during the continuous rollover, there is no control means to keep the torque stably maintained within the preset range, so that the torque generated by each rotating part is not easily maintained in the preset range during the continuous rollover (for example, (The torque generated at each flip angle may be inconsistent or not in the preset range). In view of this, in order to provide a structure different from conventional technology and improve the above-mentioned shortcomings, and to avoid relying solely on a plurality of rotating pieces of each rotating part to provide a supporting role, the creators have accumulated many years of experience and continuous research and development, Then the creation of this creation.

One of the purposes of this creation is to provide a hinge module for a folding device, which can solve the problem of the large overall volume of the conventional technology in Case 1 which is not conducive to the overall design, so as to effectively reduce the overall thickness to facilitate design and reduce other zero The impact of component size; and the lack of effective synchronization, control of torque and coordinated and stable torque support control in the previous case 2, and the synchronous action of the gears drives the slider to slide relative to the sleeve to form a torque With continuous and stable torque support, it can also share the load.

Pitch, in order to reduce the overall volume, is conducive to design, and to meet the market demand for thin overall volume.
2. The first swinging piece and the second swinging piece in this creation can generate a free swinging effect similar to a seesaw when the whole is folded and flattened, without the need to pivot either end as a conventional technique. Therefore, the whole bending In this case, an accommodating space can be provided to accommodate the curved intermediate portion of the flexible display, and when flattened as a whole, it can form a stable support for the flat intermediate portion of the flexible display.
