Description

Rotary 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.

A conventional folding electronic device, as shown in the "Foldable Display" patent of No. CN105788452 A of the People's Republic of China, discloses a folding structure of a rotating shaft, which is mainly a first body and a third body of a hinge member. Separating the first support member and the second support member with each other, and combining the first support member and the second support member with a flexible display module, so that after the first body and the third body are rotated relative to the second body, The flexible display modules on the first support and the second support are folded together. Because of 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 spacing between the two bodies that can be reserved for the rotation of the shaft. This design will make the overall volume larger. Not only is it not conducive to the overall design of the electronic device, and does not meet the market demand for the overall volume gradually becoming lighter and thinner.

As shown in the three patents of CN103576775A, CN106205385A and US9250733B, the two bodies are formed in a relatively open state by a biaxial shaft or an approximately two-axis structure; and the "support structure" of the three patents. One end is pivoted through the "solid shaft" and the other end is moved. When the entire "folding device" is closed, each supporting structure in the two bodies is subjected to another force applying member, such as a spring, The tension spring, the suction iron and the torsion spring drive an internal accommodation space for accommodating the curved intermediate portion of the flexible display, and respectively support the flexible display with each support structure when the entire folding device is flattened. Flatten the middle part. In the case of the invention of the People's Republic of China, the "Folding Equipment" patent case of CN106255935A and the "Display System" patent case of CN103034293B, the first link is made of one or two first links, respectively. The displacement of the "support structure" pivoted by the "solid shaft" is promoted to achieve the effect of reducing the pitch to accommodate the "flexible portion of the flexible display". The design concept of such a mechanism for compensating the folding path is also shown in the US9791892B and US10001810B cases, wherein the US9791892B case can be regarded as the extension of Figures 16a-16c of CN106255935A, and the US10001810B case is in one case. The body (220 of Fig. 2 and 920 of Fig. 9) is provided with a "mechanism capable of compensating the folding path", including a translating plate (225 of Fig. 2 and part 921 of Fig. 9), and a first link member (330 of Fig. 2) The guides (331 of Fig. 9 and 341 of Fig. 10a) are matched with the gear assembly (340 of Fig. 9) or the gear assembly (340 of Fig. 10a) to achieve the effect of compensating for the difference in the folding path.

However, the connection relationships and structures of the various components used in the above-mentioned patents are "complex mechanisms for compensating the folding path", and most of them use a direct pivoting structure, which is not ideal in terms of transmission stability, and When the "support structure" is displaced so that the reduced pitch is accommodated to accommodate the "flexible portion of the flexible display", the speed of the reduction is the same or too slow due to the relative movement, and the force of the folding action is likely to be uneven or The displacement structure of the "support structure" is not fast enough to quickly form a space that can accommodate the "flexible portion of the flexible display", thereby causing a pull or push on the flexible display, causing wrinkles in the middle curved portion of the flexible display.

Injury to the flexible display 13.

The second link 37 is an elongated rod body, the second link 37 is juxtaposed on one side of the linking plate 34 and the moving member 345, and the second link 37 has a reverse first end and a second end. The first end of the second link 37 is connected to the fixed housing 111, the second end of the second link 37 is connected to the second pivot 371, and the second pivot 371 is pivotally connected to the first pivot of the base 2. The portion 21 is configured to rotate the second pivot 371 and the second link 37 in synchronization with the fixed housing 111. A second guiding surface 372 is disposed adjacent to the second end of the second connecting rod 37. The second guiding surface 372 is a plane extending obliquely downward from the second end; a second supporting surface The 373 abuts the second guiding surface 372 and forms an angle with the second guiding surface 372. The second supporting surface 373 is a plane extending away from the one end of the second guiding surface 372 and extending obliquely upward. The second guiding surface 372 and the second supporting surface 373 are respectively disposed on the two sides of the linking plate 34 corresponding to the first guiding surface 312 and the first supporting surface 314 of the first connecting rod 31 respectively.

Therefore, when the first housing 11 and the second housing 12 are oppositely unfolded to be in a flattened state, the limiting portion 333 at one end of the support plate 331 can pass through the first guiding surface 312 and the second guiding surface 372. The guiding is provided on the first stopping portion 23 of the base 2 with a smooth overlapping limit, thereby restricting the actuation of the supporting plate body 33, and the two supporting plates 331 support the flexible display 13 upward. At this time, the reset members 335 of the first slip mechanism 3 and the second slip mechanism 3' are respectively stretched to accumulate the elastic force.

As shown in FIGS. 7-9, when the first housing 11 and the second housing 12 are reversely closed and the two sets of the fixed housing (111, 121) and the movable housing (112, 122) are respectively opened apart, the first Simultaneous actuation of the sliding mechanism 3 and the second sliding mechanism 3' and elastic recovery of the two resetting members 335, so that the limiting portions 333 of the supporting plates 331 of the two sets of sliding mechanisms and the base 2 respectively The two stopper portions 23 and the second stopper portion 26 are slidably separated from each other, so that the two stopper portions 333 are simultaneously separated from the restriction of the first stopper portion 23 and the second stopper portion 26, and the two support plate bodies 33 are allowed to be separated. The two first sliders 32 are respectively oscillated in an arc, so that the two support plates 331 are respectively offset by an angle, and the two connecting plates 332 are respectively pressed against the inclined surface 322 of one end of each of the first sliders 32, and The supporting plates 331 are pressed against the first supporting surface 314 and the second supporting surface 373 to form a plurality of contact surfaces to share the load and uniformly support, and the laminated structure of the linking plate 34 can be lying flat on the limiting groove. The bottom surface of the groove of 349 prevents the support plate 331 from interfering with the interlocking plate 34 when it bears. Since the two support plates 331 of the two sliding mechanisms are relatively offset by an angle, an accommodating space 14 is formed to accommodate the intermediate curved portion of the flexible display 13.

Please refer to the seventh, 10, and 11 diagrams, in the process of the first housing 11 and the second housing 12 being reversely closed, the third sliding portion 362 at one end of the intermediate transmission member 36 is coupled with the moving member 345. A sliding portion 348 is disposed, and the fourth sliding portion 363 at the other end of the intermediate transmission member 36 is received in the second sliding portion 352 in the V-shaped groove 351 of the linking member 35. When the intermediate transmission member 36 first rotates by a rotation angle θ to simultaneously move the moving member 345 and the linkage member 35 and moves in parallel in the opposite direction, if the horizontal movement distance of the moving member 345 is set to S1, the relative horizontal movement of the linkage member 35 is performed. When the distance is set to S2, S1 = r1 (the distance from the axis of the first sliding portion 348 to the fulcrum 361) * tan θ (rotation angle) S2 = r2 (the distance from the axis of the fourth sliding portion 363 to the fulcrum 361) * sin θ (rotation angle) Therefore, S1 < S2, wherein if the intermediate transmission member 36 is rotated by a rotation angle θ, the same one rotation angle θ is continued to be rotated, and during this period, the relative horizontal movement distance of the linkage member 35 is set to S3. S3 < S2; Similarly, the horizontal moving distance of the moving member 345 is also greater than the distance of S1, which will be described later with the technical features of the present invention.

Therefore, when the intermediate transmission member 36 is rotated at a constant speed in the original direction of the fulcrum 361, the linked moving member 345 is formed to move horizontally between the long and short distances before and after the rotation, so as to generate the first fast and then slow. The speed moves, and the linked linkage 35 also moves parallel to the opposite direction of the moving member 345 at a speed that is faster and slower. Therefore, in the initial stage of the operation of the first housing 11 and the second housing 12 relative to the reverse closing (which can be regarded as the intermediate transmission member 36 first rotating by a rotation angle θ degrees), the limiting portion 333 of the support plate 331 and the base 2 can be made. The first stopping portion 23 is quickly separated, so that the two supporting plates 331 are relatively offset by an angle to gradually form the accommodating space 14 which can accommodate the intermediate curved portion of the flexible display 13, in the process of the flexible display 13 The intermediate curved portion moves in a direction away from the base 2 in synchronization. When the first housing 11 and the second housing 12 are relatively reversed and closed, the intermediate transmission member 36 can be continuously rotated by the same rotation angle θ, because the moving distance of the moving member 345 and the linking member 35 are simultaneously When the size is small, the intermediate curved portion of the flexible display 13 can be prevented from being completely separated from the support of the base 2, so that the base 2 and the two support plates 331 respectively provide the intermediate curved portion of the flexible display 13 from different directions, thereby making the nail The intermediate curved portion of the sexual display 13 can be effectively accommodated in the accommodating space 14 to prevent the intermediate curved portion from being pressed or suspended, and to avoid the effect of compensating for the folded path.

Therefore, the present invention has the following advantages: 1. The invention can effectively reduce the "compensation folding path mechanism" through the connection relationship and structural features between the first slider, the support plate body, the linkage plate and a cam link module. The overall simplification of the use of parts to reduce production costs. And the second connecting portion of the supporting plate body is curved and oscillated relative to the first connecting portion of the first sliding block, thereby generating a free swinging action similar to the shaftless slab, that is, without the physical axis pivoting as in the prior art, Helps reduce the volume and reduce the thickness, so as to facilitate the effect of thinning, so that when the whole is bent, the accommodating space can be accommodated to accommodate the curved intermediate portion of the flexible display, and the flexibility can be achieved when the whole is flattened. The flattened intermediate portion of the display forms a stable support. 2. The present invention forms a relative movement by interposing an intermediate transmission member having a third sliding portion at one end to interlock the first sliding portion of the linkage plate, and a fourth sliding portion at the other end of the intermediate transmission member to interlock the linkage member. The second sliding portion moves the linking member in a direction opposite to the linking plate, so that it can be formed in the folding process of the fixed housing connecting the first sliding portion and the movable housing connecting the linking member. The effect of the movement is to achieve the effect of compensating for the difference of the folding path, so that the space for accommodating the curved portion of the flexible display can be formed more quickly, and the force of the folding action can be prevented from pulling or pushing the flexible display, thereby extending the flexible display. The service life. 3. When the first housing and the second housing of the present invention are relatively reversed and unfolded, the limiting portion at one end of the supporting plate can be guided through the first guiding surface and the second guiding surface to make the limiting portion smooth. The movement and the overlapping limit are located on the first stopping portion of the base, so that the two supporting plates simultaneously support the flexible display at the same time, so that the stable transmission effect can be ensured when the supporting plate is bent and deformed.

The present invention has been disclosed in order to achieve the above objects, but it is not intended to limit the structural features of the present invention. It should be understood by those of ordinary skill in the art that, in the technical spirit of the present invention, Variations or modifications are possible and are covered by the scope of the patent application of the present invention.
