Description

Rotating shaft module of folding device (3)

The invention relates to a rotating shaft, in particular to a rotating shaft module of a folding electronic device.

Traditional folding electronic devices, as shown in the Patent Foldable Display of Patent Publication No. CN105788452 A of the People’s Republic of China, show a folding structure of a rotating shaft, which is mainly composed of a first body and a third body of a hinge Are respectively connected to the first support member and the second support member, and the first support member and the second support member are combined with a flexible display module, so that after the first body and the third body rotate relative to the second body, the The flexible display modules on the first support and the second support are folded together. Due to the need to provide a structure on the second body that allows the first and third bodies to rotate, it is not possible to effectively reduce the space between the two bodies that can be reserved for the rotating shaft. This design will increase the overall volume. Not only is it not conducive to the overall design of the electronic device, but also does not meet the market demand that the overall volume gradually becomes lighter and thinner.

As shown in the three patent cases of CN103576775A, CN106205385A, and US9250733B, the two bodies are relatively opened and closed with a two-axis rotating shaft or an approximately two-axis structure; and the "support structure" of these three patent cases All one end is pivotally connected through the "solid shaft" and the other end is movable. When the entire "folding device" is closed, each support structure in the two bodies will be subjected to another urging member, such as: spring, Driven by tension springs, iron suction, and torsion springs, an internal accommodating space is provided for accommodating the curved middle part of the flexible display, and flattened throughout the folding device At this time, each support structure separately supports the flattened middle portion of the flexible display. Another example is the invention of the People's Republic of China that published the patent case No. CN106255935A "Folding Equipment" and the patent case No. CN103034293B "Display System", which were made of one or two first links into the first link, respectively. Pushing the "support structure" pivotally connected by the "solid axis" to produce displacement, so as to reduce the spacing to accommodate the "flexible display bending part" effect. The design concept of this "compensation mechanism that can compensate for the folding path" is also shown in the two cases of US9791892B and US10001810B. Among them, the case of US9791892B can be regarded as an extension of Figures 16a~16c of CN106255935A, and the case of US10001810B is in one. The body (220 in FIG. 2 and 920 in FIG. 9) is provided with a "mechanism that can compensate for the folding path", including a translation plate (225 in FIG. 2 and 921 in FIG. 9), and a first link member (330 in FIG. 2) With 920 of FIG. 9) or the gear assembly (340 of FIG. 10a), a guide (331 of FIG. 9 and 341 of FIG. 10a) is used to compensate for the difference in folding path.

However, the connection relationship and structure of each part of the "mechanism that can compensate for the folding path" used in the above patent cases are quite complicated, and most of them use a direct pivot connection structure, which is not ideal in terms of transmission stability, and its In the process of displacement of the "support structure" to achieve the reduced pitch to accommodate the "flexible display bending part", because the relative movement to reduce the speed is the same or too slow, it is easy to cause the force of the folding action to be uneven or It is because the displacement speed of the "support structure" is not fast enough to quickly form a space that can accommodate the "flexible display bending part", thereby causing the phenomenon of pulling or pushing on the flexible display, causing wrinkles in the middle bending part of the flexible display Fold or peel.

And in the whole bending and flattening, when the second connecting portion of the supporting plate body swings relative to the first connecting portion of the first slider in an arc shape, a free swinging effect similar to a shaftless seesaw can be generated to maintain the stability of the transmission . It does not need to be pivotally connected with a solid axis as in the conventional technology.

The flat middle part forms a stable support.

The linking member 35 is a rectangular body. The linking member 35 and the first link 31 are juxtaposed with each other. The linking member 35 is upwardly connected to the flat plate 114 of the movable housing 112. The top of the linking member 35 has a V-shaped slot 351, V-shaped The slot 351 has a laterally long guide slot, which serves as the second sliding portion 352.

As shown in Figs. 7-9, when the first casing 11 and the second casing 12 are relatively closed and closed to allow the two sets of fixed casings (111, 121) and movable casings (112, 122) to be separated from each other by Simultaneous operation of the sliding mechanism 3 and the second sliding mechanism 3'and the elastic recovery of the two resetting members 335 can make the limiting portions 333 of the support plates 331 of the two sliding mechanisms and the second The first stop portion 23 and the second stop portion 26 slide relatively apart, so that the two limit portions 333 are separated from the first stop portion 23 and the second stop at the same time The two support plates 33 are respectively oscillated with respect to the two first sliders 32, so that the two support plates 331 are offset by an angle, and the two connecting plates 332 are pressed The inclined surface 322 at one end of each first slider 32, and each support plate 331 is pressed against the first support surface 314 and the second support surface 373, thereby forming a plurality of contact surfaces to share the load and evenly support, and make the linkage The laminated structure of the plate 34 can lie flat on the bottom surface of the groove of the limiting groove 349 to prevent the support plate 331 from interfering with the interlocking plate 34 when it bears. Since the two supporting plates 331 of the two sliding mechanisms are relatively offset by an angle, an accommodating space 14 is formed to accommodate the middle curved portion of the flexible display 13.

Please also refer to Figures 7, 10, and 11, as the first housing 11 and the second housing 12 are relatively closed and closed, the third sliding portion 362 at one end of the intermediate transmission member 36 interlocks with the moving member 345. A sliding portion 348, and the fourth sliding portion 363 at the other end of the intermediate transmission member 36 is accommodated in the second sliding portion 352 in the V-shaped slot 351 of the linking member 35. When the intermediate transmission member 36 is first rotated by a rotation angle θ to simultaneously link the moving member 345 and the linking member 35 and move in parallel in the opposite direction, if the horizontal moving distance of the moving member 345 is set to S1, the relative horizontal movement of the linking member 35 The distance is set to S2, then S1=r1 (the distance from the axis of the first sliding part 348 to the fulcrum 361)*tan θ (rotation angle)

S2=r2 (the distance between the axis of the fourth sliding part 363 and the fulcrum 361) *sin θ (rotation angle)

Therefore, S1<S2

Wherein, if the intermediate transmission member 36 rotates by a rotation angle θ, and then continues to rotate by the same rotation angle θ, during this period, the relative horizontal movement distance of the linking member 35 is set to S3, then S3<S2; Similarly, the moving member The horizontal movement distance of 345 is also greater than the distance of S1. The technical features of the present invention will be described later.

Therefore, when the intermediate transmission member 36 rotates at a fixed speed on the spot with the fulcrum 361 as the axis, the linked moving member 345 forms long and short horizontal movements before and after the rotation, so as to produce a quick first and then a slow one. The speed moves, and the linked interlocking member 35 will also move in parallel with the moving member 345 in the opposite direction at a faster speed then a slower speed. With this, the first casing 11 and the second casing 12 are relatively closed and closed. In the initial stage (considered that the intermediate transmission member 36 is first rotated by a rotation angle θ degree), the limit portion 333 of the support plate 331 and the first stop portion 23 of the base 2 can be quickly separated, so that the two support plates 331 are opposed to each other It is offset by an angle to gradually form an accommodating space 14 that can accommodate the middle curved portion of the flexible display 13. During this process, the middle curved portion of the flexible display 13 moves synchronously away from the base 2. In the continuous phase of the action that the first casing 11 and the second casing 12 are relatively turned over and closed (can be regarded as the intermediate transmission member 36 is rotated and then rotated by the same rotation angle θ), since the moving distances of the moving member 345 and the linking member 35 are simultaneously Becomes smaller, it can prevent the middle curved portion of the flexible display 13 from completely disengaging from the support of the base 2, so that the base 2 and the two supporting plates 331 respectively provide the middle curved portion of the flexible display 13 to lean from different directions, so that The middle curved portion of the sexual display 13 can be effectively accommodated in the accommodating space 14 to prevent the middle curved portion from being pressed or suspended, and to avoid weakening the effect of compensating the folding path.

Therefore, the present invention has the following advantages:

1. The present invention can effectively thin the whole of the "compensation folding path mechanism" through the connection relationship and structural characteristics between the first slider, the support plate body, the link plate and a cam link module, which can further simplify the use of parts To reduce production costs. The second connecting portion of the support plate body swings relative to the first connecting portion of the first slider in an arc shape to produce a free swinging effect similar to a shaftless seesaw, that is, it does not need to be pivotally connected with a physical axis as in conventional technology. Helps to reduce the volume and thickness, in favor of the effect of thinning, so that when the whole is bent, it can make a room to accommodate the curved middle part of the flexible display, and when the whole is flat, it can be flexible The flattened middle part of the display forms a stable support.

2. The present invention forms a relative movement through an intermediate transmission member having a third sliding portion at one end to link the first sliding portion of the interlocking plate, and a fourth sliding portion at the other end of the intermediate transmission member to have the interlocking linking member The second sliding part allows the linking member to move in the opposite direction to the linking plate. Therefore, during the folding process of the fixed housing connecting the first sliding portion and the movable housing connecting the linking member, it can form a fast first and then a slow one. Move effect to achieve compensable folding path Poor efficiency makes it possible to quickly form a space that can accommodate the bending part of the flexible display, and can avoid the pulling force or pushing of the flexible display by the force of the folding action, thereby extending the service life of the flexible display.

3. When the first shell and the second shell of the present invention are relatively reversed and unfolded, the limiting portion at one end of the support plate can be guided through the first guiding surface and the second guiding surface to make the limiting portion smooth The movement is then limited to the first stop portion of the base, so that the two support plates simultaneously support the flexible display, so that when the support plate is bent and deformed, it can still ensure a stable transmission effect.

Although the present invention discloses preferred specific embodiments for achieving the above purpose, it is not intended to limit the structural features of the present invention. Any person of ordinary knowledge in the technical field should know that, under the technical spirit of the present invention, any Changes and modifications are possible, and are covered by the patent application scope of the invention.
