Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings of the present specification.

The embodiment of the disclosure provides a flexible enclosure and an electronic device with the flexible enclosure. Flexibility may refer to bending properties as well as torsional properties. The following embodiments take an electronic device as a mobile phone as an example, and the embodiments of the flexible chassis are explained.

Referring to fig. 1, fig. 1 is an exploded view of an electronic device having a flexible housing 1 according to an embodiment. The electronic device may be a mobile phone, a tablet computer, etc. In one embodiment, the flexible enclosure 1 includes a housing 11, a spindle mechanism 12, a fan assembly 13; the housing 11 includes at least two sub-housings 111; the rotating shaft mechanism 12 comprises a base 121 and a rotating shaft part 122 arranged on the base 121, wherein the rotating shaft part 122 is connected between two adjacent sub-housings 111 so as to adjust an included angle between the two sub-housings 111; the fan assembly 13 is arranged in the rotating shaft mechanism 12, and the airflow generated by the fan assembly 13 passes through the rotating shaft mechanism 12 to clean foreign matters in the rotating shaft mechanism 12.

For an electronic device with a display 2, the housing 11 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 2 on the other hand. The shape of the housing 11 is different according to the type of the electronic device. For example, the housing 11 may be circular, oval, rectangular, square, star-shaped, or the like. In order to make the housing 11 flexible, the housing 11 is divided into a plurality of sub-housings 111, and two adjacent sub-housings 111 are connected by the rotating shaft mechanism 12. By means of the rotating shaft mechanism 12, the angle between two adjacent sub-housings 111 can be changed, so that the housing 11 has the characteristics of flexibility such as folding, twisting and the like.

In one embodiment, the housing 11 is divided into a left sub-housing 111 and a right sub-housing 111, with reference to the orientation in fig. 1. The spindle mechanism 12 is installed between the left sub-housing 111 and the right sub-housing 111. The rotating shaft mechanism 12 has at least two states, namely a folded state and an unfolded state, and when the rotating shaft mechanism 12 is in the unfolded state, an included angle between the left sub-shell 111 and the right sub-shell 111 is approximately 180 degrees; when the rotating shaft mechanism 12 is in the folded state, the left sub-housing 111 and the right sub-housing 111 are attached together. Illustratively, when the hinge mechanism 12 is in the unfolded state, the display screen 2 is exposed, and the electronic device is in the working state; when the hinge mechanism 12 is in the folded state, the display screen 2 is folded accordingly, and the electronic device is in an inoperative state, for example, in a standby state.

With continuing reference to fig. 1 and with reference to fig. 2, fig. 2 is a schematic structural diagram illustrating the assembled spindle mechanism 12 and fan assembly 13 according to an embodiment. The base 121 of the rotating shaft mechanism 12 extends substantially along the width direction of the housing 11 and is disposed between the two sub-housings 111, the rotating shaft portion 122 of the rotating shaft mechanism 12 is fixedly disposed on the base 121, and the rotating shaft portion 122 includes a rotating shaft and two fixing portions connected to the rotating shaft. The two fixing portions are correspondingly connected to the two sub-housings 111, respectively. The two fixing portions can rotate along the axial direction of the rotating shaft, so that the two sub-housings 111 jointly realize the unfolded state and the folded state. In one embodiment, the fixing portion of the rotating shaft mechanism 12 is fixedly connected to the sub-housing 111 by protruding into the sub-housing 111.

An appropriate number of the spindle mechanisms 12 may be provided depending on the size of the housing 11 and the size of the spindle mechanism 12, and one or more spindle mechanisms 12 may be provided. In a specific embodiment, there are two spindle mechanisms 12, which are respectively disposed in sequence along the length direction of the base 121 and are symmetrical along the center of the base 121, so as to improve the stability of the flexible housing 11 when being bent.

Since the rotating shaft mechanism 12 and the sub-housing 111 are assembled and connected together, there is a small gap at the joint of the two, and foreign matters such as dust and particles enter the rotating shaft mechanism 12 through the gap, and in the past, the foreign matters are accumulated in the rotating shaft mechanism 12, thereby causing the abnormal operation of the rotating shaft. In this embodiment, the fan assembly 13 is provided to clean foreign matters in the rotating shaft mechanism 12. The fan rotates to drive the air in the rotating shaft mechanism 12 to rotate together, so that air flow is formed in the rotating shaft mechanism 12, the air flow with a certain speed can drive foreign matters in the rotating shaft mechanism 12, and the effect of cleaning the rotating shaft mechanism 12 is achieved. Therefore, the flexible casing 1 of the embodiment of the present disclosure can realize a cleaning effect on the rotating shaft mechanism 12, which is helpful for keeping the rotating shaft mechanism 12 with good performance, and improving the service life of the flexible casing 1.

There are at least two embodiments of the fan assembly 13, one is to blow out the foreign objects by blowing air into the rotating shaft mechanism 12, and the other is to suck air into the rotating shaft mechanism 12 to suck the foreign objects. In the following examples, these two examples will be described in detail.

Please continue with fig. 2. In one embodiment, the base 121 has a vent 1211; the vent 1211 communicates with the outside of the flexible casing 1; the fan assembly 13 includes a cleaning fan 131, and the airflow generated by the cleaning fan 131 is used to drive the foreign matters in the rotating shaft mechanism 12 to be discharged from the vent 1211. In this embodiment, when the cleaning fan 131 works, air can be supplied through the gap in the flexible housing 1, which is communicated with the outside. The ventilation holes 1211 are used for exhausting air, and when the air flow generated by the cleaning fan 131 flows along the rotating shaft mechanism 12, the air flow blows up the foreign matters in the rotating shaft mechanism 12, drives the foreign matters to flow together, and is finally discharged from the ventilation holes 1211, thereby achieving the effect of cleaning the foreign matters in the rotating shaft mechanism 12.

The cleaning fan 131 may be disposed on the rotating shaft or on the base 121. In this embodiment, in order to improve the working stability of the cleaning fan 131, the influence of the rotating shaft 122 on the operation of the cleaning fan 131 during the rotation process is avoided. In an embodiment, the cleaning fan 131 is fixedly disposed on the base 121, and is located on the same side of the base 121 as the rotating shaft portion 122. Referring to fig. 3 to 7, fig. 3 is a schematic structural diagram illustrating the flexible enclosure 1 in an unfolded state according to an embodiment; FIG. 4 is the cross-sectional view of FIG. 3 along a viewing angle shown in accordance with an embodiment; FIG. 5 is the cross-sectional view of FIG. 3 shown from another perspective according to an embodiment; fig. 6 is a schematic diagram illustrating the flexible enclosure 1 in a folded configuration according to an embodiment. Fig. 3 to 7 show the position of the cleaning fan 131 in the flexible enclosure 1 when the flexible enclosure 1 is in the unfolded state and the folded state, respectively. It can be seen that the cleaning fan 131 is shielded by the base 121 from the outside of the flexible casing 1, and thus does not affect the appearance of the flexible casing 1.

In one embodiment, the axial direction of the rotating shaft 122 corresponds to the length direction of the base 121; the cleaning fan 131 discharges air along the length direction of the base 121, at least two sets of the vent holes 1211 are disposed on the base 121, and the two sets of the vent holes 1211 are arranged along the length direction of the base 121 and are respectively located at two sides of the cleaning fan 131, so that when the cleaning fan 131 works, one set of the vent holes 1211 is used for supplying air, and the other set of the vent holes 1211 is used for discharging air, so as to form a stable airflow circulation channel. The number of the vent holes 1211 included in the set of vent holes 1211 is not limited herein, and may be one or more. The vent holes 1211 of the plurality of vent holes 1211 may be arranged along a length direction of the base 121 or along a width direction of the base 121.

In one embodiment, the cleaning fan 131 may be disposed in the middle of the two sets of vents 1211 or near the vents 1211 for air intake. Since the space in the spindle mechanism 12 is small, a negative pressure of a certain degree occurs in the space between the ventilating hole 1211 for air intake and the cleaning fan 131, so that foreign matters in the space are cleaned by the suction force of the cleaning fan 131 and flow along the length direction of the base 121 until being discharged from the ventilating hole 1211 for air exhaust. In another embodiment, there are two rotating shafts 122, and the rotating shafts are sequentially arranged along the length direction of the base 121; the cleaning fan 131 may be disposed between the two rotating shafts. Of course, the cleaning fan 131 may be disposed at the center of the base 121 along its own length.

In this embodiment, the axial direction of the rotating shaft portion 122 refers to the axial direction of the rotating shaft portion 122. The base 121 is substantially in a strip shape, and the length direction of the base 121 corresponds to the axial direction of the rotating shaft portion 122, so that the cleaning fan 131 is arranged to blow air along the length direction of the base 121 in this embodiment, so that more wind blown out by the cleaning fan 131 can cover the base 121, and the cleaning effect on the foreign matters on the base 121 is improved.

In one embodiment, the cleaning fan 131 may be an axial fan. The axial flow fan has larger air volume, so that the air outlet range can cover most positions in the rotating shaft mechanism 12, thereby improving the comprehensiveness of cleaning foreign matters and having smaller cleaning dead angles.

In another embodiment, the cleaning fan 131 may be a centrifugal fan. The centrifugal fan has larger wind pressure, and the wind can blow the deposited foreign matters, so that the thoroughness of cleaning the foreign matters can be improved.

Moreover, the number of the cleaning fans 131 may be more than one, and may be set according to the air output of the cleaning fans 131 and the size of the rotating shaft mechanism 12. For example, two or three fans may be disposed along the length of the base 121, and optionally, the air outlet directions of the two or three fans are the same, so as to generate the same airflow direction.

As for the power supply to the cleaning fan 131, a power supply may be built in the spindle mechanism 12 to supply power to the cleaning fan 131. Optionally, a power supply in the electronic device is used to supply power to the cleaning fan 131. Electronic devices will typically have a power module therein, which may be a battery and/or a power circuit capable of receiving mains power. Accordingly, the cleaning fan 131 may be powered by a power supply module within the electronic device.

Regarding control of the cleaning fan 131. In order to adjust the air outlet range of the cleaning fan 131, in an embodiment, the cleaning fan 131 includes a fan blade and a driving motor 1311, and the driving motor 1311 is configured to drive the fan blade to rotate to generate an air flow and to drive the fan blade to rotate to adjust the blowing direction. Therefore, the fan blades can be controlled by the driving motor 1311 to wind in all directions, so that the wind outlet range can cover most of the rotating shaft mechanism 12, and the foreign matter cleaning effect is improved. Of course, the driving motor 1311 may also control the rotation speed of the fan, and when there are more foreign matters or the adhesion of the foreign matters is strong, the driving motor 1311 may be controlled to increase the rotation speed of the fan to improve the cleaning capability of the foreign matters.

The control of the cleaning fan 131 is the control of the driving motor 1311. In one embodiment, the driving motor 1311 is electrically connected to the control circuit 3 of the electronic device, and thus the operation of the driving motor 1311 is controlled by the control circuit 3. The control scheme of the control circuit 3 for the driving motor 1311 has at least two types: firstly, the control circuit 3 controls the driving motor 1311 to be started periodically to clean the inside of the rotating shaft mechanism 12; alternatively, the control circuit 3 receives a user's instruction, and activates the driving motor 1311 to clean the inside of the rotating shaft mechanism 12.

The rotation speed and the air outlet direction of the cleaning fan 131 are adjusted. The control circuit 3 may control the driving motor 1311 to adjust to the corresponding air outlet angle and/or air outlet speed at the corresponding time according to a preset cleaning process. Illustratively, the preset cleaning process may be to blow air at 30 rpm for 1 minute along the length of the susceptor 121, blow air at 30 rpm for 1 minute … … along the width of the susceptor 121, and so on when the cleaning fan 131 is activated. Of course, the control circuit 3 may also adjust the rotation speed and the air outlet direction of the cleaning fan 131 according to the instruction of the user. A user can send an instruction by touching the display screen 2 of the electronic equipment; or by means of voice control or remote control, which is not limited in this respect.

Please continue to refer to fig. 4 to fig. 6. Further, in order to discharge the foreign matters from the ventilation holes 1211 more orderly in the process of cleaning the foreign matters, in an embodiment, a cleaning channel 1212 is formed in the base 121, and the cleaning channel 1212 is groove-shaped; the cleaning fan 131 is arranged in the cleaning channel 1212, and an air outlet direction of the cleaning fan 131 corresponds to an extending direction of the cleaning channel 1212; the vent 1211 is opened on the cleaning channel 1212. In this embodiment, when the cleaning fan 131 works, the cleaning channel 1212 can guide the wind blown out by the cleaning fan 131, so as to be beneficial to increasing the wind pressure, and the cleaning channel 1212 can also limit the part of the foreign matters flowing along with the airflow in the cleaning channel 1212, so as to prevent the foreign matters from floating to other parts in the rotating shaft mechanism 12, thereby causing ineffective cleaning. The cleaning channels 1212 in this embodiment therefore enhance the cleaning of the spindle mechanism 12.

In one embodiment, two air vents 1211 are disposed on two sides of the cleaning fan 131, and the air vents 1211 are disposed at two ends of the cleaning channel 1212, respectively.

With continued reference to FIG. 1, the flexible housing 11 further includes a shielding member 14, wherein the shielding member 14 is detachably connected to the vent 1211 to shield the vent 1211. When the flexible casing 1 is in the expanded state, the ventilation holes 1211 are blocked by the sub-housing 111 and are not exposed. When the flexible casing 1 is folded, the air hole 1211 is exposed to communicate with the outside. When the cleaning of the rotating shaft mechanism 12 is not required, the air vent 1211 can be shielded by the shielding member 14 to prevent foreign matters from entering the rotating shaft mechanism 12 from the air vent 1211; when it is necessary to clean the spindle mechanism 12, the shutter 14 is separated from the air vent 1211, so that air enters from the air vent 1211, or air flow in the spindle mechanism 12 flows out from the air vent 1211.

In a specific embodiment, the shutter 14 is a plug that is received in the vent 1211 to block the vent 1211. Of course, the cover 14 may be a lid for closing the opening of the ventilation opening 1211.

In another embodiment of the fan assembly 13, the foreign objects are sucked by drawing air into the rotating shaft mechanism 12. Specifically, in an embodiment, the cleaning fan 131 is an exhaust fan, and the fan assembly 13 further includes a negative pressure cavity; the cleaning fan 131 is used for pumping the foreign matters in the rotating shaft mechanism 12 into the negative pressure cavity. In this embodiment, the cleaning fan 131 sucks the air in the rotating shaft into the negative pressure chamber, and during the flowing process of the air flow, the foreign matters in the rotating shaft mechanism 12 are sucked into the negative pressure chamber together. When more foreign matters exist in the negative pressure cavity, the negative pressure cavity can be taken out by disassembling the rotating shaft mechanism 12. The fan assembly 13 may be embedded in the base 121 and may be directly taken out of the base 121. When more foreign matter is accumulated in the negative pressure chamber, the fan assembly 13 can be replaced with a new fan assembly 13 by taking the fan assembly 13 out of the base 121.

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 2 and a flexible housing 1; the flexible casing 1 is arranged on one side of the display screen 2 to support the display screen 2; the display 2 has flexibility to be bent together with the flexible casing 1 when the flexible casing 1 is bent.

The specific structure of the flexible enclosure 1 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.

In one embodiment, the electronic device has a power supply module therein, and the power supply module may be a battery and/or a power supply circuit capable of receiving commercial power. Accordingly, the cleaning fan 131 may be powered by a power supply module within the electronic device.

Further, referring to fig. 8, fig. 8 is a circuit control block diagram of an electronic device according to an embodiment. In one embodiment, the cleaning fan 131 includes blades and a driving motor 1311, and the driving motor 1311 is used for driving the blades to rotate to generate an air flow and for driving the blades to rotate to adjust a blowing direction. The electronic device has a control circuit 3, and the control circuit 3 is electrically connected to the drive motor 1311, so that the operation of the drive motor 1311 is controlled by the control circuit 3. The control circuit 3 may be an SOC of an electronic device, or an MCU chip.

The control circuit 3 controls the fan blades through the driving motor 1311, so that the fan blades can exhaust air in all directions, the exhaust range can cover most of the area of the rotating shaft mechanism 12, and the foreign matter cleaning effect is improved. Of course, the driving motor 1311 may also control the rotation speed of the fan, and when there are more foreign matters or the adhesion of the foreign matters is strong, the driving motor 1311 may be controlled to increase the rotation speed of the fan to improve the cleaning capability of the foreign matters.

In one embodiment, the control circuit 3 controls the driving motor 1311 to be started periodically to clean the inside of the rotating shaft mechanism 12; in another embodiment, the control circuit 3 receives a user's instruction, and activates the driving motor 1311 to clean the inside of the rotating shaft mechanism 12.

As the present disclosure may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
