The embodiment of the present disclosure provides a flexible chassis 1 assembly and an electronic device having the flexible chassis 1 assembly. Flexibility may refer to bending properties as well as torsional properties. The following embodiments are provided as examples, and an electronic device is taken as a mobile phone, and the following embodiments of the assembly of the flexible casing 1 will be described.

Referring to fig. 1, fig. 1 is an exploded view of an electronic device having a flexible housing 1 assembly according to an embodiment. In one embodiment, the flexible enclosure 1 assembly includes an enclosure 1, a seal 3. The casing 1 comprises a shell and a rotating shaft mechanism 2, the shell comprises at least two sub-shells 11, and the rotating shaft mechanism 2 is connected between two adjacent sub-shells 11 so that the shell can be bent; the sealing member 3 is disposed in the sub-housing 11 and located between the inner surface of the sub-housing 11 and the rotating shaft mechanism 2, so as to at least fill a part of the gap between the inner surface of the sub-housing 11 and the rotating shaft mechanism 2.

For an electronic device with a display screen 6, the housing is used for accommodating part of the hardware of the electronic device, such as a main control board, an antenna, a battery, etc., on the one hand, and for carrying the display screen 6 on the other hand. The shape of the housing is different according to the type of the electronic device. For example, the housing may be circular, oval, rectangular, square, star-shaped, or the like. In order to make the housing flexible, the housing is divided into a plurality of sub-housings 11, and two adjacent sub-housings 11 are connected by the rotating shaft mechanism 2. By means of the rotating shaft mechanism 2, the angle between two adjacent sub-housings 11 can be changed, so that the housings have the characteristics of flexibility such as folding, twisting and the like.

In a particular embodiment, the housing is divided into a left sub-housing 11 and a right sub-housing 11, with the orientation in fig. 1 being a reference. The spindle mechanism 2 is installed between the left sub-housing 11 and the right sub-housing 11. The rotating shaft mechanism 2 has at least two states, namely a folded state and an unfolded state, and when the rotating shaft mechanism 2 is in the unfolded state, an included angle between the left sub-shell 11 and the right sub-shell 11 is approximately 180 degrees; when the rotating shaft mechanism 2 is in the folded state, the left sub-housing 11 and the right sub-housing 11 are attached together. Schematically, when the rotating shaft mechanism 2 is in the unfolded state, the display screen 6 is exposed, and the electronic device is in the working state; when the rotating shaft mechanism 2 is in the folded state, the display screen 6 is folded accordingly, and the electronic device is in an inoperative state, for example, in a standby state.

In one embodiment, continuing with the orientation of fig. 1, the arrangement is such that along the length of the housing, the housing is divided into two sub-housings 11. The base 21 of the spindle mechanism 2 extends substantially in the width direction of the housing and is disposed between the two sub-housings 11. The rotating shaft mechanism 2 comprises a base 21 and a rotating shaft part 22 arranged on the base 21; the rotating shaft part 22 is connected between two adjacent sub-housings 11 so as to adjust the included angle between the two sub-housings 11; the sealing member 3 is located between the inner surface of the sub-housing 11 and the base 21 to fill at least a part of the gap between the inner surface of the sub-housing 11 and the spindle mechanism 2. Illustratively, two sides of the rotating shaft portion 22 of the rotating shaft mechanism 2 respectively protrude into the two sub-housings 11 to achieve a fixed connection with the two sub-housings 11.

In order to switch the flexible housing 1 assembly between the unfolded state and the folded state, a gap is left between the inner wall of the sub-housing 11 and the base 21 of the hinge mechanism 2 in the unfolded state, and most of the base 21 slides out of the inner wall of the sub-housing 11 when the flexible housing 1 assembly is in the folded state, and is exposed to the environment, so that foreign matters in the environment, such as dust, can enter between the base 21 and the inner wall of the sub-housing 11. In the past, dust accumulates between the base 21 and the inner wall of the sub-housing 11, which tends to cause abnormal rotation of the rotating shaft mechanism 2 and even affect the operation of the electronic device. In this embodiment, by disposing the sealing member 3 in the sub-housing 11, the sealing member 3 is located between the inner surface of the sub-housing 11 and the rotating shaft mechanism 2, so as to fill at least a part of the gap between the sub-housing 11 and the rotating shaft mechanism 2, or even fill the whole gap; thereby the effectual entry that can supply external environment dust, get into in the casing that has reduced, the effectual dustproof performance who improves flexible casing 1 subassembly.

Referring to fig. 2, fig. 2 is an exploded view of the assembly of the flexible housing 1 according to an embodiment. In order to further improve the dustproof performance of the flexible casing 1 assembly, in an embodiment, the flexible casing 1 assembly further comprises an ejector mechanism 4, and the ejector mechanism 4 is used for ejecting the sealing member 3, so as to further reduce the sealing effect of the sealing member 3 between the inner surface of the sub-housing 11 and the rotating shaft mechanism 2. The ejection mechanism 4 is provided in at least two positions.

Fig. 3 to 5 show a first embodiment of the setting position of the ejector mechanism 4. Wherein fig. 3 is a schematic cross-sectional view of the assembly of the flexible cover 1 corresponding to fig. 2; FIG. 4 is an enlarged view of the structure at A in FIG. 3; fig. 5 is a schematic sectional view of the assembly of the flexible cover 1 along the arrangement direction of the sub-housings 11 according to an embodiment. In the first embodiment, the urging mechanism 4 is provided between the inner surface of the sub-housing 11 and the seal member 3, and the urging mechanism 4 can urge the seal member 3 to reduce the clearance between the seal member 3 and the rotation shaft mechanism 2. In a specific embodiment, the ejector mechanism 4 can push the sealing member 3 to a position where it is attached to the rotating shaft mechanism 2, and the sealing member 3 and the ejector mechanism 4 cooperate to almost completely seal the gap between the inner surface of the sub-housing 11 and the sealing member 3. In this embodiment, the elastic member 41 and the seal member 3 may be both provided on the inner surface of the housing, but it is also possible that the elastic member 41 is provided on the inner surface of the housing and the seal member 3 is provided on the rotation shaft mechanism 2.

With the orientation shown in fig. 3 as a reference, the pushing mechanism 4 and the sealing member 3 are both located between the inner surface of the sub-housing 11 and the rotating shaft mechanism 2, the rotating shaft mechanism 2 is located above the inner surface of the sub-housing 11, the pushing mechanism 4 is disposed on the inner surface of the sub-housing 11, and the pushing mechanism 4 pushes the sealing member 3 upward to make the sealing member 3 adhere to the lower surface of the base 21 of the rotating shaft mechanism 2.

In the second embodiment, the ejector mechanism 4 is provided on the base 21 of the spindle mechanism 2, and the ejector mechanism 4 can reduce the clearance between the seal 3 and the inner surface of the sub-housing 11 by pushing the seal 3 downward. In one embodiment, the ejection mechanism 4 ejects the seal 3 into contact with the inner surface of the sub-housing 11, thereby effectively reducing or even eliminating the significant gap between the base 21 of the spindle mechanism 2 and the inner surface of the sub-housing 11.

In this embodiment, the elastic member 41 and the seal member 3 may be both provided on the rotating shaft mechanism 2, but it is also possible that the elastic member 41 is provided on the rotating shaft mechanism 2 and the seal member 3 is provided on the inner surface of the housing.

Through the setting of ejection mechanism 4, no matter be in the expansion state at casing 1, fold condition, or in the transition process of expansion state and fold condition, all can make sealing member 3 keep under the ejecting force of ejection mechanism 4 with the contact of pivot mechanism 2 base 21 (or keep with sub-casing 11 inner wall contact), the effectual clearance that reduces between sub-casing 11 internal surface and the pivot mechanism 2 to the dustproof performance of casing 1 has further been improved.

Please continue to refer to fig. 3 and 4. When the pushing mechanism 4 is disposed between the sealing member 3 and the inner wall of the sub-housing 11, stability and reliability of the pushing mechanism 4 pushing the sealing member 3 are improved in order to fix the relative positions of the pushing mechanism 4 and the sealing member 3. In an embodiment, the flexible enclosure 1 further includes a positioning element 5, the positioning element 5 is convexly disposed on the inner surface of the sub-housing 11, and sequentially penetrates through the pushing mechanism 4 and the sealing element 3 to position the inner surface of the housing, and the relative positions between the pushing mechanism 4 and the sealing element 3.

It should be noted that, for the two sub-housings 11 connected by the rotating shaft mechanism 2, the sealing member 3 and the pushing mechanism 4 as a set may be disposed in one of the two sub-housings 11, or may be disposed in both sub-housings 11, so as to protect both sub-housings 11 from dust. In the solution shown in fig. 2, a set of sealing elements 3 and ejection means 4 is provided in correspondence of both sub-housings 11.

In the following embodiments, an embodiment of the ejector mechanism 4 will be explained.

Please continue to refer to fig. 2 to 5. In an embodiment, corresponding to the first embodiment, the pushing mechanism 4 includes an elastic member 41, and the elastic member 41 is disposed between the inner surface of the sub-housing 11 and the sealing member 3 for providing the sealing member 3 with a pushing force toward the rotating shaft mechanism 2. In this embodiment, the elastic member 41, the sealing member 3 and the spindle mechanism 2 may be stacked together by adhesion. Of course, the rotating shaft mechanism 2 may also be provided with a positioning column, and the elastic member 41 and the sealing member 3 are sleeved on the positioning column.

In this embodiment, the elastic member 41 may be a spring plate, a spring, or the like. The elastic part 41 and the sealing part 3 are both provided with through holes, the positioning column is convexly arranged on the inner surface of the sub-shell 11, and the elastic part 41 and the sealing part 3 are sleeved on the positioning column. Optionally, the positioning column does not protrude from the sealing member 3, so as to prevent interference with the relative sliding between the sealing member 3 and the rotating shaft mechanism 2.

Taking the elastic sheet as an example, when the casing 1 is in the expanded state, the folded state, or in the transition process between the expanded state and the folded state, the elastic sheet is always in the pressed state, so that the elastic force can be generated on the sealing member 3, and the sealing member 3 is kept attached to the rotating shaft mechanism 2.

In order to improve the stability of the sealing member 3 when it is pushed, in an embodiment, a plurality of resilient tabs may be provided to collectively push the sealing member 3, and the positional arrangement of the plurality of resilient tabs may be provided in combination with the shape and size of the sealing rod. In one embodiment, the sealing rod is a long table, and two elastic pieces are arranged and respectively arranged corresponding to two ends of the sealing rod.

In another embodiment, corresponding to the second embodiment, the elastic member 41 is disposed between the base 21 of the rotating shaft mechanism 2 and the sealing member 3 for providing the sealing member 3 with a pushing force toward the inner surface of the sub-housing 11. In this embodiment, the elastic member 41 and the sealing member 3 may be both disposed on the inner surface of the housing, or both may be disposed on the rotating shaft mechanism 2, or the elastic member 41 may be disposed on the rotating shaft mechanism 2 and the sealing member 3 may be disposed on the inner surface of the housing.

As to the pushing mechanism 4, please refer to fig. 6 to 9 for another embodiment. FIG. 6 is an exploded view of the assembly of the flexible cover 1 according to another embodiment; fig. 7 is a schematic cross-sectional view of the assembly of the flexible cover 1 corresponding to fig. 6; FIG. 8 is an enlarged view of the structure at B in FIG. 7; fig. 9 is a schematic sectional view of the assembly of the flexible cover 1 along the arrangement direction of the sub-housings 11 according to an embodiment. I.e. using magnetic force to push the seal 3.

Specifically, the pushing mechanism 4 includes a first magnetic member 42 and a second magnetic member 43 that are mutually exclusive, and corresponding to the first embodiment, the first magnetic member 42 and the second magnetic member 43 are disposed between the inner surface of the sub-housing 11 and the sealing member 3, the first magnetic member 42 is fixedly connected with the inner surface of the sub-housing 11, and the second magnetic member 43 is fixedly connected with the sealing member 3; or corresponding to the second embodiment, the first magnetic member 42 and the second magnetic member are disposed between the base 21 of the rotating shaft mechanism 2 and the sealing member 3, and the first magnetic member 42 is fixedly connected with the rotating shaft mechanism 2, and the second magnetic member 43 is fixedly connected with the sealing member 3.

In this embodiment, the first magnetic member 42 and the second magnetic member 43 are magnets having the same magnetic pole. The first magnetic member 42 and the second magnetic member 43 may have the same size and shape. Illustratively, the first magnetic member 42 and the second magnetic member 43 are substantially sheet-shaped, and may not have a shape or area corresponding to the sealing member 3. As long as the repulsive force between the first magnetic member 42 and the second magnetic member 43 can push the sealing member 3 to fit the rotating shaft mechanism 2.

Specifically, several sets of the first magnetic member 42 and the second magnetic member 43 (one set of the first magnetic member 42 and the second magnetic member 43) may be provided according to the shape and size of the sealing member 3. When the sealing member 3 is long, a set of the first magnetic member 42 and the second magnetic member 43 may be respectively disposed corresponding to both ends of the sealing member 3, so that the sealing member 3 may move more stably when receiving the urging force.

In an embodiment, when the first magnetic member 42, the second magnetic member 43, and the sealing member 3 are fixed, the positioning member 5 is protruded on the inner surface of the sub-housing 11 or the rotating shaft mechanism 2, and the first magnetic member 42, the second magnetic member 43, and the sealing member 3 are all provided with through holes so as to be sleeved on the positioning member 5.

Further, when the housing 1 is switched between the folded state and the unfolded state, sliding friction occurs between the sealing member 3 and the rotating shaft mechanism 2 when the sealing member 3 is fixed in the sub-housing 11. Therefore, in order to reduce the sliding friction force and avoid excessive wear of the parts, in an embodiment, the flexible casing 1 assembly further includes a buffer layer for reducing the sliding friction force, and the buffer layer is disposed between the rotating shaft mechanism 2 and the sealing rod. When the packing 3 is fixed to the rotary shaft assembly, sliding friction occurs between the packing 3 and the inner wall of the sub-housing 11. Correspondingly, the buffer layer is arranged between the sealing rod and the inner surface of the sub-housing 11. The buffer layer can be a soft rubber layer which can be correspondingly coated on the sealing element 3, the inner wall of the sub-shell 11 or the rotating shaft mechanism 2.

In order to make the sub-housing 11 and the rotating shaft mechanism 2 better fit, the end surface of one end of the sub-housing 11 connected with the rotating shaft mechanism 2 is an arc surface, and the arc surface is matched with the shape of the base 21; thus, when the housings are in the unfolded state, the ends of two adjacent sub-housings 11 are complementary to each other to form an arc-shaped slot. When the housing is in the unfolded state, the slot wall of the arc slot is attached to the outer surface of the base 21 of the rotating shaft mechanism 2, so that when the housing is in the unfolded state, the base 21 is accommodated in the two sub-housings 11.

In one embodiment, the sealing member 3 is correspondingly disposed at the edge of the end of the sub-housing 11 connected to the rotating shaft mechanism 2. It can be understood that the cavity in the sub-housing 11 corresponding to the side of the sealing member 3 can be protected from dust by the sealing member 3, and therefore, by disposing the sealing member 3 close to the edge of the sub-housing 11, the dust-proof performance of the assembly of the flexible enclosure 1 can be improved. Schematically, taking the mobile phone shell 1 as an example, the sub-shells 11 are arranged corresponding to the length direction of the shell; the sealing member 3 is strip-shaped and extends along the width direction of the inner surface of the sub-housing 11.

The embodiment of the disclosure also provides an electronic device, which may be a mobile phone, a tablet computer, a notebook computer, a wearable device, and the like. In one embodiment, the electronic device comprises a display screen 6 and a flexible cover 1 assembly; the flexible casing 1 assembly is arranged on one side of the display screen 6 to support the display screen 6; the display screen 6 has flexibility to bend with the flexible chassis 1 assembly when the flexible chassis 1 assembly is bent.

The specific structure of the flexible enclosure 1 assembly refers to the above embodiments, and since the electronic device adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.
