As shown in connection with fig. 2 and 4, in some embodiments, the housing assembly 10 includes a first housing 12 and a second housing 14, with a spindle mechanism 30 coupled between the first housing 12 and the second housing 14 such that the first housing 12 and the second housing 14 are capable of relative rotation. Specifically, the first housing 12 is connected to the first transmission member 33, and the second housing 14 is connected to the second transmission member 34. The first transmission member 33 and the second transmission member 34 based on the rotation shaft mechanism 30 are both rotatable with respect to the base 31, so that such an arrangement can satisfy the relative rotation requirement of the first housing 12 and the second housing 14. It will be appreciated that the flexible screen 20 is connected between the first housing 12 and the second housing 14, and that the flexible screen 20 covers the hinge mechanism 30 to maintain the overall aesthetic appearance of the foldable electronic device 100. In this embodiment, when the first housing 12 and the second housing 14 are folded to each other about the central axis Z0, the slider 32 slides relative to the base 31, and the first protrusion 32a and the second protrusion 32b slide along the first spiral groove 33a and the second spiral groove 34a, respectively.
The first axis Z1 and the second axis Z2 are parallel and symmetrical about the central axis Z0, so that the flexible screen 20 can be folded or unfolded stably at a position corresponding to the central axis Z0 when the folding electronic device 100 is folded.
In some embodiments, folding electronic device 100 may be manually folded and unfolded, or folding electronic device 100 may be implemented by a driving member disposed within folding electronic device 100. Illustratively, the slider 32 is connected to a driving member, and the driving member is used for driving the slider 32 to slide relative to the base 31, so that the first protrusion 32a and the second protrusion 32b of the slider 32 slide along the first spiral groove 33a and the second spiral groove 34a, respectively, and then the first rotating portion 331 and the second rotating portion 341 rotate relative to the base 31, so that the first casing 12 and the second casing 14 can be folded and unfolded by using the first driving member 33 and the second driving member 34, and folding and unfolding of the foldable electronic device 100 can be achieved.
The direction of rotation of the second spiral groove 34a is opposite to the direction of rotation of the first spiral groove 33a, and the pitch of the second spiral groove 34a is the same as the pitch of the first spiral groove 33a, and the opposite direction of rotation means that the first spiral groove 33a and the second spiral groove 34a are arranged around opposite directions, that is, if one of the first spiral groove 33a and the second spiral groove 34a is arranged in a forward spiral and the other is arranged in a reverse spiral. In this embodiment, since the pitch of the second spiral groove 34a is the same as the pitch of the first spiral groove 33a, when the driving member drives the slider 32 to slide relative to the base 31, the slider 32 synchronously drives the first rotating portion 331 and the second rotating portion 341 to rotate by the same angle relative to the base 31 in opposite directions via the first protrusion 32a and the second protrusion 32b, so that the first housing 12 and the second housing 14 synchronously rotate relative to the base 31 during the folding movement of the folding electronic device 100, and the use experience is improved.
In some embodiments, the spindle mechanism 30 further includes a detection component disposed between the slider 32 and the base 31 for detecting a position of the slider 32 relative to the base 31. Since the sliding block 32 is in transmission connection with the first transmission member 33 and the second transmission member 34 through the first protrusion 32a and the second protrusion 32b, in the sliding process of the sliding block 32 relative to the base 31, the first transmission member 33 and the second transmission member 34 rotate relative to the base 31, and then the position of the sliding block 32 relative to the base 31 is detected by using the detection assembly, the rotation positions of the first transmission member 33 and the second transmission member 34 in corresponding states relative to the base 31 can be known, so that the detection of the unfolding angle of the foldable electronic device 100 is realized. Here, the expansion angle of the foldable electronic device 100 refers to a folding angle that occurs with respect to the folded position. With the folding position, the unfolding angle of the folding electronic device 100 is 0 °, and if the folding electronic device 100 is in the unfolding position, the display surface of the flexible screen 20 is flattened, and the unfolding angle of the folding electronic device 100 is 180 °.
In some embodiments, as shown in fig. 5, the rotating shaft mechanism 30 further includes a first rotating assembly 35 and a second rotating assembly 36 disposed on two sides of the base 31, and the first rotating assembly 35 and the second rotating assembly 36 are respectively connected with the first swing arm 332 and the second swing arm 342 in a linkage manner. Here, the linkage connection means that one of the two structural members moves and the other also moves together. In this embodiment, the first rotating unit 35 and the second rotating unit 36 are connected to the first housing 12 and the second housing 14, respectively, and the first housing 12 and the first swing arm 332 are connected to each other in a linked manner based on the linkage connection between the first rotating unit 35 and the first swing arm 332, and the second housing 14 and the second swing arm 342 are connected to each other in a linked manner based on the linkage connection between the second rotating unit 36 and the second swing arm 342. In this manner, the relative movement between the first housing 12 and the second housing 14 is associated with the relative movement between the first swing arm 332 and the second swing arm 342, so that the first rotating assembly 35 and the second rotating assembly 36 can adapt to the state switching of the rotating shaft mechanism 30 in the rotating process, so as to adapt to the use requirement of the foldable electronic device 100 under different folding angles.
With continued reference to fig. 5, in some embodiments, the first rotating assembly 35 includes a first rotating member 351 and a first connecting seat 352. One end of the first rotating member 351 is rotatably connected to the base 31, and the other end is rotatably connected to the first connecting seat 352, and the first connecting seat 352 is slidably connected to the first swing arm 332. The second rotating assembly 36 includes a second rotating member 361 and a second connecting seat 362, one end of the second rotating member 361 is rotatably connected with the base 31, the other end is rotatably connected with the second connecting seat 362, and the second connecting seat 362 is slidably connected with the second swing arm 342. In this way, during the rotation of the first connecting seat 352 and the second connecting seat 362 relative to the base 31 through the first rotating member 351 and the second rotating member 361, the first swing arm 332 and the second swing arm 342 slide relative to the first connecting seat 352 and the second connecting seat 362 while rotating relative to the base 31, so as to maintain the rotation coordination of the first rotating assembly 35 and the second rotating assembly 36 on two sides of the base 31.
As shown in fig. 6 and 7, the rotation shaft mechanism 30 includes a first inclined plate 353 and a second inclined plate 363, the first inclined plate 353 and the second inclined plate 363 are respectively connected to the first rotation component 35 and the second rotation component 36, and when the first swing arm 332 and the second swing arm 342 rotate relative to the base 31, the first inclined plate 353 and the second inclined plate 363 are respectively driven by the first rotation component 35 and the second rotation component 36 to move relative to the base 31 so as to present different states. For example, as shown in fig. 6, the first inclined plate 353 and the second inclined plate 363 are horizontally extended, and as shown in fig. 7, the first inclined plate 353 and the second inclined plate 363 are disposed at a certain angle. In this manner, the support and compression of the flexible screen 20 can be achieved using the movement of the first and second tilting plates 353 and 363. Specifically, when the foldable electronic device 100 is in the flattened position, the first and second tilt plates 353 and 363 are flattened to support the flexible screen 20, so that the flexible screen 20 displays a flat screen. When the foldable electronic device 100 is in the folded position, the first inclined plate 353 and the second inclined plate 363 form a certain included angle and are respectively located at two sides of the folded position of the flexible screen 20, and a portion of the flexible screen 20 close to the rotating shaft mechanism 30 is in a droplet shape under the extrusion of the first inclined plate 353 and the second inclined plate 363, so that the probability of crease occurrence of the flexible screen 20 is reduced.
As shown in fig. 8 and 9, one of the first connection seat 352 and the first inclined plate 353 is provided with a first circular arc groove 353a, and the other is provided with a first engagement portion 352a slidably engaged with the first circular arc groove 353 a. Here, in the present application, the circular arc groove refers to a groove having a circular arc cross section. Thus, in this embodiment, the cross-sectional shape of the first engagement portion 352a is circular arc. When the first swing arm 332 rotates about the first axis Z1 relative to the base 31, the first mating portion 352a slides along the first circular arc groove 353a, the first connecting seat 352 slides relative to the first swing arm 332, and the first swing arm 332 drives the first inclined plate 353 to rotate about the geometric center of the first mating portion 352a relative to the first connecting seat 352.
One of the second connecting seat 362 and the second inclined plate 363 is provided with a second circular arc slot 363a, the other one of the second connecting seat 362 and the second inclined plate 363 is provided with a second matching part 362a in sliding fit with the second circular arc slot 363a, when the second swing arm 342 rotates around the second axis Z2 relative to the base 31, the second matching part 362a slides along the second circular arc slot 363a, the second connecting seat 362 slides relative to the second swing arm 342, and the second swing arm 342 drives the second inclined plate 363 to rotate around the geometric center of the second matching part 362a relative to the second connecting seat 362.

In some embodiments, when the first swing arm 332 and the second swing arm 342 move to the extreme positions in the directions away from each other, the first inclined plate 353 and the second inclined plate 363 form an angle of 180 °, and the flexible screen 20 approaches a plane under the support of the first inclined plate 353 and the second inclined plate 363 within the range of values, so as to improve the flatness of the display screen. Understandably, in consideration of engineering errors, the included angle between the first inclined plate 353 and the second inclined plate 363 may be in a range from 175 ° to 185 °, where the included angle between the first inclined plate 353 and the second inclined plate 363 is close to a flat angle, and then the first inclined plate 353 and the second inclined plate 363 are coplanar with each other, so as to support the flexible screen 20 together, which has little influence on the flatness of the display screen of the flexible screen 20, and still can maintain the texture of the display screen of the flexible screen 20.
As shown in fig. 11, the base 31 has a first shaft 31a and a second shaft 31b parallel to each other, and the first rotating member 351 and the second rotating member 361 are rotatably coupled to the first shaft 31a and the second shaft 31b, respectively, so that the first rotating member 351 and the second rotating member 361 can smoothly rotate with respect to the base 31 and the first coupling seat 352 and the second coupling seat 362 can stably deflect with respect to the base 31.
The rotation axis of the first shaft 31a is parallel to the first axis Z1, and thus the first rotation member 351 and the first transmission member 33 rotate about different axes, and form a high rotation pair and a low rotation pair, respectively, to realize a biaxial rotation pair. Accordingly, the rotation axis of the second shaft 31b is parallel to the second axis Z2, whereby the second rotation member 361 and the second transmission member 34 rotate about different axes, and form respective high and low pairs of rotation, also realizing a biaxial pair of rotation.
As shown in fig. 11 to 13, the spindle mechanism 30 further includes a cover plate 37, and the cover plate 37 has a first receiving groove 37a and a second receiving groove 37b. In this embodiment, at least part of the first rotating member 351 is received in the first receiving groove 37a, and at least part of the second rotating member 361 is received in the second receiving groove 37b, so that the assembly structure is compact, so that the rotating mechanism is compact, and the miniaturization of the folding electronic apparatus 100 is facilitated. In this embodiment, the cover 37 is connected to the base 31 for rotatably limiting the first rotating member 351 and the second rotating member 361 to the first shaft 31a and the second shaft 31b, so that the structure of the rotating shaft mechanism 30 is stable to maintain good rotation performance.
As shown in fig. 13, the first receiving groove 37a and the second receiving groove 37b may be circular arc surface grooves, and the circular arc surface grooves refer to surfaces surrounding the grooves as circular arc surfaces, and the cross section of the grooves may be considered to be circular arc. It is understood that the first and second transmission members 33 and 34 can smoothly rotate between the cover 37 and the base 31 after the cover 37 and the base 31 are coupled.
In some embodiments, the cross sections of the first shaft 31a and the second shaft 31b are in a sector shape, the first rotating member 351 is clamped between the first shaft 31a and the cover plate 37, and the second rotating member 361 is clamped between the second shaft 31b and the cover plate 37, so that the structural volume can be reduced as much as possible, and the supporting surface provided by the non-cylindrical shaft is flat, so that the supporting effect on the flexible screen 20 is good. The cross-section of the first shaft 31a and the second shaft 31b may be semicircular.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
