Referring to fig. 1-5, an electronic device 100 according to an embodiment of the present application includes a housing assembly 10, a flexible display 20, and a drive mechanism 30. The housing assembly 10 includes a first housing 11, a second housing 12, and a third housing 13, the second housing 12 and the third housing 13 being disposed at both sides of the first housing 11, respectively, and both being slidably connected with the first housing 11. The flexible display 20 comprises a first portion 21, a second portion 22 and a third portion 23. The first portion 21 is fixedly connected to the first housing 11, the second portion 22 is connected to one end of the first portion 21, the third portion 23 is connected to the other end of the first portion 21, and both the second portion 22 and the third portion 23 can be hidden within the housing assembly 10 (as shown in fig. 1 and 3). The second shell 12 is slidable relative to the first shell 11 in a direction away from each other to at least partially deploy the second portion 22 out of the shell assembly 10, and the third shell 13 is slidable relative to the first shell 11 in a direction away from each other to at least partially deploy the third portion 23 out of the shell assembly 10 (as shown in fig. 2 and 4). The driving mechanism 30 is mounted on the first housing 11, the driving mechanism 30 is connected to the second housing 12 and the third housing 13, respectively, and the driving mechanism 30 is capable of driving the second housing 12 to slide in a direction away from each other with respect to the first housing 11, and simultaneously driving the third housing 13 to slide in a direction away from each other with respect to the first housing 11.

In the electronic device 100 of the present embodiment, when the area of the display area of the electronic device 100 needs to be enlarged, the second casing 23 and the third casing 13 can be simultaneously driven by one driving mechanism 30 to slide in the direction away from each other relative to the first casing 11, so that the second portion 22 and the third portion 23 of the flexible display 20 can be simultaneously at least partially exposed from the casing assembly 10, and the first portion 21 and the exposed second portion 22 and third portion 23 can form the display area of the electronic device 100 together, so that the display area becomes larger. In this way, the electronic device 100 can have different display areas in different states to meet different use requirements of users.

It is understood that the electronic device 100 according to the embodiment of the present application includes, but is not limited to, a mobile terminal such as a mobile phone, a tablet computer, or other portable electronic devices, and in the embodiment of the present application, the electronic device 100 is exemplified as a mobile phone.

In particular, as shown in fig. 3-4, the material of the housing assembly 10 may be a lightweight and relatively hard metal or plastic, etc., and is not particularly limited in this application. The second and third cases 12 and 13 are provided on both sides of the first case 11, respectively, and the second and third cases 12 and 13 are slidably connected to the first case 11, or, so to speak, the second and third cases 12 and 13 are slidable to both sides at a predetermined speed with respect to the first case 11. For example, the second housing 12 and the third housing 13 can each be slid relative to the first housing 11 to a first position, in which the electronic device 100 is in a retracted state, and the second portion 22 and the third portion 23 of the flexible display 20 are retracted into the housing assembly 10, as shown in fig. 1 and 3, such that substantially only the first portion 21 of the electronic device 100 is located outside the housing assembly 10 and the display area is small. As shown in fig. 2 and 4, in the second position, the electronic device 100 is in the unfolded state, and the second portion 22 and the third portion 23 of the flexible display 20 are at least partially unfolded out of the housing assembly 10 to form a display portion of the electronic device 100 together with the first portion 21, so that the display area is larger.

As shown in fig. 1 and 3, when the second shell 12 and the third shell 13 slide to the first position relative to the first shell 11 (i.e. when the electronic device 100 is in the recovered state), the second shell 12 and the third shell 13 at least partially overlap with the first shell 11, and are embedded together, so that the electronic device 100 is in the recovered state, and the electronic device 100 has a smaller volume and is convenient to carry. As shown in fig. 2 and fig. 4, when the second shell 12 and the third shell 13 slide to the second position relative to the first shell 11, the second shell 12 and the third shell 13 are separated from the first shell 11, and the three are separated from each other by the overlapping state, so that the electronic device 100 is in the unfolded state, and the electronic device 100 can have a larger display area, so that the user operation experience can be improved.

As can be appreciated, referring to fig. 1 and 3, in the illustrated embodiment, when the electronic device 100 is in the recovered state, the second casing 12 and the third casing 13 are spliced and embedded with each other, the first casing 11 may be accommodated in the second casing 12 and the third casing 13, and the second casing 12 and the third casing 13 together form an external casing of the electronic device 100, so that the volume of the electronic device 100 is smaller. Of course, it should be understood that in other embodiments, when the electronic device 100 is in the recovered state, the second casing 12 and the third casing 13 may be completely contained in the first casing 11, and the first casing 11 may form an external casing of the electronic device, which is not limited herein.

Referring to fig. 5 and 6, in the illustrated embodiment, a housing cavity 113 is formed on a side of the first housing 11 opposite to the flexible display 20, for mounting components such as the battery 60 and the motherboard 70, where the motherboard 70 is electrically connected to the flexible display 20, and the battery 60 is capable of supplying power to the flexible display 20 and the electronic components on the motherboard 70.

Referring to fig. 6-8, the flexible display 20 has a bendable characteristic, a first portion 21 of the flexible display 20 may be fixedly connected to a side of the first shell 11 facing away from the accommodating cavity 113, a second portion 22 and a third portion 23 are respectively connected to two ends of the first portion 21, no obvious connection trace exists at a connection position between the first portion 21 and the second portion 22 and the third portion 23, and both the second portion 22 and the third portion 23 can be hidden in the shell assembly 10. The second portion 22 may follow the second housing 12 to be at least partially deployed outside the housing assembly 10 when the second housing 12 slides in a direction away from each other with respect to the first housing 11, and the third portion 23 may follow the third housing 13 to be at least partially deployed outside the housing assembly 10 when the third housing 13 slides in a direction away from each other with respect to the first housing 11.

Referring to fig. 7 and 8, in an embodiment of the present application, when both the second portion 22 and the third portion 23 of the flexible display 20 are completely hidden within the housing assembly 10, the second portion 22 and the third portion 23 have at least a partial overlap. In this way, when the electronic device 100 is in the recovered state, the second portion 22 and the third portion 23 may be stacked along the thickness direction of the electronic device 100 to further reduce the size of the electronic device 100 in the lateral direction for portability.

As shown in fig. 6, the driving mechanism 30 may be installed in the receiving chamber 113 of the first housing 11. The driving mechanism 30 is connected to the second case 12 and the third case 13, respectively, and the driving mechanism 30 is capable of driving the second case 12 to slide in a direction away from each other with respect to the first case 11, and is also capable of driving the third case 13 to slide in a direction away from each other with respect to the first case 11. Meanwhile, the driving mechanism 30 may also slide in a direction to drive the second casing 12 to approach each other with respect to the first casing 11, and may also drive the third casing 13 to slide in a direction to approach each other with respect to the first casing 11. In other words, the driving mechanism 30 may drive the second casing 12 and the third casing 13 to slide simultaneously in a direction away from the first casing 11 or to slide simultaneously in a direction toward the first casing 11.

Referring to fig. 5, 9 and 10, in some embodiments, the driving mechanism 30 includes a motor 31 and a transmission assembly 32, the motor 31 is mounted on the first housing 11, and the transmission assembly 32 includes a first transmission structure 321 and a second transmission structure 322 connected to the first transmission structure 321.

The first transmission structure 321 is mounted on the first housing 11 and connected to the motor 31 and the second housing 12, respectively, and the second transmission structure 322 is mounted on the first housing 11 and connected to the first transmission structure 321 and the third housing 13, respectively.

The motor 31 can drive the second shell 12 to slide relative to the first shell 11 through the first transmission structure 321, and simultaneously drive the second transmission structure 322 to move through the first transmission structure 321 so as to drive the third shell 13 to slide relative to the first shell 11.

In this way, the electronic device 100 can drive the second shell 12 and the third shell 13 to slide relative to the first shell 11 through the first transmission structure 321 and the second transmission structure 322 respectively by one motor 31, so that the internal space is saved, and the volume of the electronic device 100 is reduced.

Specifically, as shown in fig. 9, the motor 31 is installed in the accommodating cavity 113 of the first housing 11, and the transmission assembly 32 may also be installed in the accommodating cavity 113 of the first housing 11, and the first transmission structure 321 and the second transmission structure 322 are connected to each other. The first transmission structure 321 is respectively connected with the motor 31 and the second shell 12, and the second transmission structure 322 is respectively connected with the first transmission structure 321 and the third shell 13, so that when the motor 31 drives the second shell 12 to slide relative to the first shell 11 through the first transmission structure 321, the second transmission structure 322 moves along with the first transmission structure 321, and the second transmission structure 322 drives the third shell 13 to slide relative to the first shell 11.

Referring to fig. 9-10, further, in some embodiments, the second housing 12 has a first rack portion 121 formed thereon. The first transmission structure 321 includes a first transmission shaft 3211 and a first transmission gear 3212 mounted on the first transmission shaft 3211, the first transmission shaft 3211 is rotatably mounted on a side of the first housing 11 near the second housing 12 and is in power coupling connection with the motor 31, the second transmission structure 322 is connected with the first transmission shaft 3211, and the first transmission gear 3212 is meshed with the first rack portion 121.

In this way, the motor 31 can drive the first transmission gear 3212 to move through the first transmission shaft 3211, the first transmission gear 3212 is meshed with the first rack portion 121, and then drives the second shell 12 to slide, so that the implementation mode is simpler, and the transmission is more stable.

Specifically, as shown in fig. 9, the first rack portion 121 is disposed perpendicular to the first transmission shaft 3211 and corresponds to the first transmission gear 3212, and the first transmission gear 3212 is meshed with the first rack portion 121 so as to drive the second casing 12 to slide. In one embodiment, the number of the first transmission gears 3212 may be two, and the first rack portions 121 may be two, and the two first rack portions 121 may be symmetrically disposed on the second shell 12 along the sliding direction perpendicular to the 12 sliding direction of the second shell, where the first transmission gears 3212 and the first rack portions 121 are meshed in a one-to-one correspondence manner, so that the second shell 12 is driven to slide by the two rack portions, so that the sliding of the second shell 12 is stable.

Of course, it will be understood that in other embodiments, the number of the first rack portions 121 and the first transmission gear 3212 may be one or more than two, and may be selected according to practical needs, for example, when the number of the first rack portions 121 and the first transmission gear 3212 is one, the first rack portions 121 and the first transmission gear 3212 may be disposed at a middle position of the second casing 12 so that two ends of the second casing 12 are stressed uniformly during sliding to ensure smooth movement, and for example, when the number of the first rack portions 121 is more than two, the first rack portions 121 may be disposed on the second casing 12 at uniform intervals along a sliding direction perpendicular to the second casing 12, which is not limited herein.

Referring to fig. 9 to 10, further, in some embodiments, the third housing 13 may have a second rack portion 131 formed thereon.

The second transmission structure 322 includes a second transmission shaft 3221, a second transmission gear 3222 mounted on the second transmission shaft 3221, and a reversing mechanism 3223, wherein the second transmission shaft 3221 is rotatably mounted on one side of the first shell 11 close to the third shell 13 and parallel to the first transmission shaft 3211, the second transmission gear 3222 is meshed with the second rack portion 131, the reversing mechanism 3223 is respectively connected with the first transmission shaft 3211 and the second transmission shaft 3221, when the motor 31 drives the first transmission shaft 3211 to rotate in a first direction, the reversing mechanism 3223 drives the second transmission shaft 3221 to rotate in a second direction under the drive of the first transmission shaft 3211, and the second direction is opposite to the first direction.

In this way, the second transmission shaft 3221 is rotated by the reversing mechanism 3223, so that the first transmission shaft 3211 and the second transmission shaft 3221 rotate in opposite directions, so that the second casing 12 and the third casing 13 can slide relative to the first casing 11 in a direction away from the first casing 11 or in a direction close to the first casing 11 at the same time, so that the second portion 22 and the third portion 23 can be simultaneously deployed out of the casing assembly 10 or retracted into the casing assembly 10.

Specifically, the first direction and the second direction may be a counterclockwise direction and a clockwise direction, respectively, and the second direction is a counterclockwise direction when the first direction is a clockwise direction and the second direction is a clockwise direction when the first direction is a counterclockwise direction. As shown in fig. 9, the second rack portion 131 is disposed perpendicular to the second transmission shaft 3221 and corresponds to the second transmission gear 3222, and the second transmission gear 3222 is meshed with the second rack portion 131 to drive the third casing 13 to slide. In one embodiment, the number of the second driving gears 3222 may be two, and the second driving gears 3221 may be connected to two ends of the second driving shaft 3221 at intervals, the number of the second rack portions 131 may also be two, the two second rack portions 131 may be symmetrically disposed on the third shell 13 along the sliding direction perpendicular to the 13 sliding direction of the third shell, and the second driving gears 3222 and the second rack portions 131 are meshed in a one-to-one correspondence manner, so that the sliding of the third shell 13 may be stabilized by driving the third shell 13 through the two rack portions.

Of course, it will be understood that in other embodiments, the number of the second driving gears 3222 and the second rack portions 131 may be one or more than two, and may be selected according to practical requirements, for example, when the number of the second driving gears 3222 and the second rack portions 131 is one, the second rack portions 131 and the second driving gears 3222 may be disposed at a position exactly in the middle of the third housing 13, so that two ends of the third housing 13 are stressed relatively uniformly during sliding to ensure smooth movement, and for example, when the number of the second driving gears 3222 and the second rack portions 131 is greater than two, the plurality of second rack portions 131 may be disposed on the third housing 13 at uniform intervals along a sliding direction perpendicular to the third housing 13, which is not limited herein.

In such an embodiment, the second driving shaft 3221 is installed in the receiving cavity 113 of the first housing 11 and near the side of the third housing 13, while the second driving shaft 3221 is parallel to the first driving shaft 3211, that is, the second driving shaft 3221 and the first driving shaft 3211 are disposed at opposite sides of the first housing 11, respectively. The reversing mechanism 3223 is mounted between the first transmission shaft 3211 and the second transmission shaft 3221, and the reversing mechanism 3223 may make the rotation directions of the first transmission shaft 3211 and the second transmission shaft 3221 opposite. For example, when the motor 31 drives the first transmission shaft 3211 to rotate clockwise, the second casing 12 slides with respect to a direction away from the first casing 11, and the second transmission shaft 3221 rotates counterclockwise by the reversing of the reversing mechanism 3223, so that the third casing 13 slides with respect to a direction away from the first casing 11. As such, the first and second transmission shafts 3211 and 3221 may rotate in opposite directions, and the second and third housings 12 and 13 may simultaneously slide in directions approaching or separating with respect to the first housing 11.

Referring to fig. 9-12, in some embodiments, the reversing mechanism 3223 includes a first reversing gear 3224, a second reversing gear 3225, a reversing shaft 3226, a third reversing gear 3227, and a fourth reversing gear 3228, the first reversing gear 3224 is mounted on the first transmission shaft 3211, the reversing shaft 3226 is rotatably disposed on the first housing 11 and perpendicular to the first transmission shaft 3211 and the second transmission shaft 3221, the second reversing gear 3225 and the third reversing gear 3227 are disposed on the reversing shaft 3226 at a distance therebetween, the second reversing gear 3225 is meshed with the first reversing gear 3224, the fourth reversing gear 3228 is mounted on the second transmission shaft 3221, and the fourth reversing gear 3228 is meshed with the third reversing gear 3227.

In this way, the first transmission shaft 3211 and the second transmission shaft 3221 may perform a common rotation by the reversing mechanism 3223, and simultaneously drive the second casing 12 and the third casing 13 to slide relative to the first casing 11.

Specifically, as shown in fig. 9, the first, second, third, and fourth reversing gears 3224, 3225, 3226, 3227, 3228 of the reversing mechanism 3223 may all be disposed within the housing cavity 113 of the first housing 11. The first reversing gear 3224, the second reversing gear 3225, the third reversing gear 3227 and the fourth reversing gear 3228 are all face gears, and the face gears are gears with tooth structures arranged on faces in the vertical axial direction. The first reversing gear 3224 is sleeved on the first transmission shaft 3211, the second reversing gear 3225 is sleeved on one end, close to the first transmission shaft 3211, of the reversing shaft 3226, the third reversing gear 3227 is sleeved on one end, close to the second transmission shaft 3221, of the reversing shaft 3226, the fourth reversing gear 3228 is sleeved on the second transmission shaft 3221, and the reversing shaft 3226 is installed between the first transmission shaft 3211 and the second transmission shaft 3221 and perpendicular to the first transmission shaft 3211 and the second transmission shaft 3221.

As shown in fig. 11, when the motor 31 drives the first transmission shaft 3211 to rotate, the first reversing gear 3224 follows the first transmission shaft 3211 to rotate, the second reversing gear 3225 is meshed with the first reversing gear 3224, the second reversing gear 3225 is driven by the first reversing gear 3224 to rotate the reversing shaft 3226 to achieve first reversing (i.e., to convert the rotation of the first transmission shaft 3211 into rotation of the reversing shaft 3226 perpendicular to the first transmission shaft 3211), in this case, as shown in fig. 12, the third reversing gear 3227 is connected with the second reversing gear 3225 through the reversing shaft 3226, the reversing shaft 3226 drives the third reversing gear 3227 to rotate, the fourth reversing gear 3228 is meshed with the third reversing gear 3227, and the fourth reversing gear 3228 is driven by the third reversing gear 3227 to drive the second transmission shaft 3221 to achieve second reversing (i.e., to convert the rotation of the reversing shaft 3226 into rotation of the second transmission shaft 3221 perpendicular to the reversing shaft 3226). Thereby, the rotation of the first transmission shaft 3211 is converted into the rotation of the second transmission shaft 3221 after the two reversals, and the rotation directions of the two transmission shafts are changed, so that the second casing 12 and the third casing 13 can be simultaneously moved away from or toward the first casing 11 to achieve the simultaneous deployment and retraction of the second section 22 and the third section 23.
