Abstract

The application relates to an electronic device including a housing assembly, a flexible display screen, and a locking mechanism. The flexible display screen is connected to the shell component, and the shell component is used for switching between an unfolding state and a folding state and driving the flexible display screen to enter and exit the shell component. A locking mechanism is provided on the housing assembly and is at least operable to energize the housing assembly in the deployed state to lock the housing assembly in the deployed state. In the electronic device, the locking mechanism is arranged on the shell assembly and is at least used for electrifying and working in the unfolding state so as to lock the shell assembly in the unfolding state. When the shell assembly is locked in the unfolded state, the shell assembly in the unfolded state can absorb impact force and maintain the unfolded state after being impacted, such as accidental falling, so that the related moving parts are prevented from generating large relative movement to protect the moving parts, and therefore the shock resistance performance of the electronic equipment is improved.

Referring to fig. 1, 2 and 3, an electronic device 100 of the present embodiment includes a case assembly 10, a flexible display 20, and a guide 30. The housing assembly 10 is hollow, and the flexible display 20, the guide 30, etc. may be disposed on the housing assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), both of which may be disposed on the housing assembly 10. The circuit board may integrate the processor, power management module, memory unit, baseband chip, etc. of the electronic device 100. The flexible display 20 is communicatively coupled to a circuit board, and the battery is capable of powering the flexible display 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module 40, where the camera module 40 is communicatively connected to the circuit board, and the battery can supply power to the camera module 40. It is understood that the electronic device 100 according to the embodiment of the present application may be, but not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 100. In the embodiment of the present application, a mobile phone will be described as an example.

Referring to fig. 3, 4 and 5, in an embodiment of the present application, the housing assembly 10 includes a first housing 12 and a second housing 14, the second housing 14 and the first housing 12 being capable of relative movement. Specifically, in the present embodiment, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 is capable of sliding relative to the first housing 12. For example, one of the first housing 12 and the second housing 14 may be provided with a slide rail along which the other can slide to cause movement of the end of the second housing 14 remote from the first housing 12 toward or away from each other with the end of the first housing 12 remote from the second housing 14.

Further, the second housing 14 is capable of sliding to a first position and a second position relative to the first housing 12. Referring to fig. 4, when the second housing 14 is in the first position, the housing assembly 10 and the electronic device 100 are in the unfolded state, so that a relatively large display area can be obtained, so as to enhance the use experience of the electronic device 100; when the second housing 14 is in the second position (see fig. 1), the housing assembly 10 and the electronic device 100 are in a collapsed state, and have a relatively small external dimension, and are convenient to carry. It is to be understood that in the embodiments that follow this application, the first position, the second position, and the like refer to the relative positions of the second housing 14 and the first housing 12. For simplicity, the similar expressions "the second housing 14 is in the first position" or "when in the first position" refer to the second housing 14 being in the first position relative to the first housing 12, i.e., the electronic device 100 being in the unfolded state, and the similar expressions "the second housing 14 is in the second position" or "when in the second position" refer to the second housing 14 being in the second position relative to the first housing 12, i.e., the housing assembly 10 and the electronic device 100 being in the folded state.

It will be appreciated that in embodiments of the present application, the electronic device 100 may also be considered to be in a deployed state when the housing assembly 10 is in a deployed state; the electronic device 100 may also be considered to be in a collapsed state when the housing assembly 10 is in a collapsed state.

In the present embodiment, the position of the end of the second housing 14 away from the first housing 12, and the end of the first housing 12 away from the second housing 14 can be more clearly determined with reference to the first position. Taking fig. 4 as an example, when the second housing 14 is at the first position, the leftmost side of the electronic device 100 in the width direction is the end of the second housing 14 away from the first housing 12, and the rightmost side of the electronic device 100 in the width direction is the end of the first housing 12 away from the second housing 14.

In the present embodiment, when the second housing 14 is in the first position, the overall width of the electronic device 100 is greater than that in the second position, so that the width dimension of the exposed flexible display 20 is variable. In other words, the electronic apparatus 100 is variable in size in the width direction. In such an embodiment, an interface of the electronic apparatus 100, such as a data line jack or a charging line jack or a headphone jack, may be provided at the end in the width direction. In other embodiments, the overall length of the electronic device 100 is greater than the length in the second position when the second housing 14 is in the first position, such that the length dimension of the exposed flexible display 20 is variable. In other words, the electronic device 100 is variable in size in the longitudinal direction. In such an embodiment, an interface of the electronic device 100, such as a data line jack or a charging line jack or a headphone jack, may be provided at an end in the length direction.

Referring to fig. 6, the flexible display 20 may include a fixed portion 20a and a free portion 20b disposed opposite to each other, where the fixed portion 20a is disposed on the first housing 12 and is fixed relative to the first housing 12. In the second position, the flexible display 20 bypasses the guide 30 and the free portion 20b of the flexible display 20 is received within the housing assembly 10 such that a portion of the flexible display 20 is hidden from the housing assembly 10 and a portion of the flexible display 20 hidden within the housing assembly 10 may not be used for display. In other words, movement of the first housing 12 relative to the second housing 14 may cause at least a portion of the free portion 20b to be deployed within the second housing 14, or the free portion 20b deployed within the second housing 14 to be retracted within the housing assembly 10.

It will be appreciated that in the embodiments of the present application, the positions of the two objects are relatively fixed, that is, the two objects cannot generate a relative motion under normal conditions or the relative motion between the two objects is negligible, and the two objects with relatively fixed positions may be physically connected directly, or may be indirectly connected through an intermediate structure. For example, the fixing portion 20a and the first housing 12 are fixed relatively, and the fixing portion 20a and the first housing 12 may be in direct contact with each other, for example, by using a threaded fastener or a clamping method, or the fixing portion 20a may be indirectly fixed to the first housing 12 by using an adhesive layer, an intermediate connection plate, or the like, for example, for the fixing portion 20a and the first housing 12.

It is understood that the fixed portion 20a and the free portion 20b can be distinguished in the following manner, when the second housing 14 is in the second position relative to the first housing 12, that is, the electronic device 100 is in the folded state, the portion of the flexible display 20 exposed outside the housing assembly 10 is the fixed portion 20a of the flexible display 20, and the portion of the flexible display 20 accommodated in the housing assembly 10 can be regarded as the free portion 20b. In some embodiments, when the second housing 14 is in the second position, i.e. the electronic device 100 is in the folded state, the fixing portion 20a exposed outside the housing assembly 10 is generally rectangular, and its size may be 5-6 inches, i.e. the size is equivalent to that of the display screen of a typical smart phone, so that the electronic device 100 is convenient to carry and use.

Further, referring to fig. 5, the second housing 14 may include a rear cover 142, the rear cover 142 covering the free portion 20b of the flexible display 20 in the second position. The rear cover 142 may be provided with a light-transmitting area, and the portion of the flexible display screen 20 that is received in the housing assembly 10 in the second position may also be used for displaying, so that a user can view information displayed on the flexible display screen 20 from the light-transmitting area, and further expand the usage scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 can implement functions such as self-timer, video call, and the like by using the rear camera module 40 without providing a front camera. The light-transmitting region may be made of transparent glass or may be an opening of the rear cover 142. After the second housing 14 slides to the first position relative to the first housing 12, at least a portion of the flexible display 20 housed in the housing assembly 10 is exposed. The exposed flexible display screen 20 may be used for display such that the electronic device 100 has a relatively large display area to enhance the user's use experience.

With continued reference to fig. 6, in the present embodiment, the guide 30 is disposed at an end of the second housing 14 away from the first housing 12, and the guide 30 can guide the flexible display 20 to deform and expand in the second housing 14 during the process of switching the second housing 14 from the second position to the first position relative to the first housing 12. The guide 30 may limit the bending radius of the flexible display 20 to a suitable range to avoid damage to the flexible display 20 caused by too small a bending radius. Of course, the guide 30 may also avoid the excessive thickness of the electronic device 100 caused by the excessive bending radius of the flexible display 20.

In some embodiments, the guide 30 may be a rotating shaft structure with protruding teeth, and the flexible display 20 is coupled to the guide 30 by engagement or the like. When the second housing 14 slides relative to the first housing 12, the guide 30 moves the portion of the flexible display 20 engaged with the guide 30 and expands or retracts the housing assembly 10.

It will be appreciated that in other embodiments, the guide 30 may also be a circular shaft without teeth attached. During the switching of the second housing 14 from the second position to the first position, the portion of the flexible display 20 attached to the guide 30 is spread by the guide 30 so that more of the flexible display 20 is exposed to the outside of the case assembly 10 and is in a flat state. In this embodiment, the guide 30 may be rotatably disposed on the second housing 14, and the guide 30 may be rotated along with the movement of the flexible display 20 during the gradual deployment of the flexible display 20, so as to reduce the resistance of the flexible display 20 during the deployment and reduce the abrasion of the contact portion of the guide 30 and the flexible display 20.

Referring to fig. 6, in the present embodiment, the guide 30 has a circular shaft shape. The electronic device 100 may further include a pulley 51 and a traction belt 53, the guide 30 being rotatably connected to an end of the second housing 14 remote from the first housing 12, the pulley 51 being rotatably connected to an end of the second housing 14 remote from the guide 30. One end of the traction belt 53 is connected to the free portion 20b, and the other end is wound around the pulley 51 and connected to the first housing 12. In this embodiment, the first housing 12 may be referred to, i.e., the position of the first housing 12 is considered to be constant, and the guide 30 and the pulley 51 function as movable pulleys, respectively. When the distance of movement of the second housing 14 relative to the first housing 12 is d, the sliding length of the free portion 20b relative to the guide 30 and the sliding length of the traction belt 53 relative to the pulley 51 are both 2d. Therefore, the cooperation of the guide member 30, the pulley 51 and the traction belt 53 can exert a tensioning effect on the free portion 20b, that is, a proper tensile force is generated in the free portion 20b by the abutting action of the guide member 30 on the free portion 20b and the abutting action of the pulley 51 on the traction belt 53, so as to avoid wrinkles or jams generated in the process of extending or retracting the flexible display screen 20 into or out of the housing assembly 10, thereby ensuring the smooth extension and retraction of the flexible display screen 20.

In other embodiments, the guide 30 may also be fixed to the second housing 14, with the guide 30 having a smooth surface. The guide 30 is slidably contacted with the flexible display 20 through a smooth surface thereof during the process of expanding the flexible display 20 to the second housing 14. In other words, in such an embodiment, the guide 30 may be integrally formed with the second housing 14 or welded into the same.

During the switching of the second housing 14 from the first position to the second position, the flexible display 20 may be retracted by the guide 30, i.e. the portion of the flexible display 20 deployed in the second housing 14 is retracted within the housing assembly 10.

Further, referring to fig. 7, 8 and 9, the electronic device 100 may include a driving mechanism 60, where the driving mechanism 60 may be disposed in the housing assembly 10, and the driving mechanism 60 may be coupled with the first housing 12 or the second housing 14 to drive the second housing 14 to move relative to the first housing 12, so as to further drive the flexible display 20 to be extended or retracted.

In some embodiments, the drive mechanism 60 includes a driver 61, a transmission rod 63, and a connecting rod 65. The driver 61 may be a stepper motor or a combination of a stepper motor and a reduction gear set. The driver 61 is connected to the first housing 12, and an output end of the driver 61 is linked with the transmission rod 63, for example, the driver 61 can drive the transmission rod 63 to rotate when being powered. The transmission rod 63 is linked with the connection rod 65, for example, the connection rod 65 and the transmission rod 63 can be screw-driven. The connecting rod 65 is connected to the second housing 14 to drive the second housing 14 to slide relative to the first housing 12.

It will be appreciated that the drive mechanism 60 may be omitted and the user may directly manually or the like move the second housing 14 and the first housing 12 relative to one another.

It will be appreciated that in this embodiment, the first and second positions may be considered as two extreme positions of movement of the second housing 14 relative to the first housing 12. In the first position, the display area of the flexible display 20 reaches a maximum, and the second housing 14 is no longer able to move relatively far away from the first housing 12 under normal conditions. In the second position, the display area of the flexible display 20 is minimized, and the second housing 14 is no longer able to move toward and away from the first housing 12 under normal conditions. The first and second positions may be achieved by providing a locking mechanism 70 on the second housing 14 or the first housing 12 or the guide 30.

A locking mechanism 70 is provided on the housing assembly 10, for example, the locking mechanism 70 may be connected to the first housing 12. In the first position, the second housing 14 engages with the locking mechanism 70, thereby restricting the movement range of the second housing 14 in the first housing 12 and restricting the second housing 14 to the first position. In other embodiments, the locking mechanism 70 may be connected to the second housing 14, and the first housing 12 may be engaged with the locking mechanism 70 in the first position, and this configuration may also reliably limit the second housing 14 to the first position.

It can be appreciated that a plurality of intermediate positions may be further disposed between the first position and the second position, so as to position the second housing 14 relative to the first housing 12 at the plurality of intermediate positions, and enable the flexible display 20 to have different display areas at different intermediate positions, thereby expanding the usage scenario of the electronic device 100. The plurality of intermediate positions may be implemented using other locking mechanisms 70.

Referring to fig. 8 and 9, a locking mechanism 70 is provided to the housing assembly 10 and is at least for energizing operation in the deployed state to lock the housing assembly 10 in the deployed state. Specifically, the lock mechanism 70 includes a driving member 71 and a telescopic member 73, the driving member 71 is connected to the first housing 12, and an output end of the driving member 71 is linked with the telescopic member 73. The driving member 71 is at least used for energizing in the unfolded state to drive the telescopic member 73 to be engaged with the second housing 14, so that the positions of the first housing 12 and the second housing 14 are relatively fixed.

Further, in some embodiments, the second housing 14 is provided with a slot 14a, and in the unfolded state, the telescopic member 73 extends into the slot 14a to fix the positions of the first housing 12 and the second housing 14 relatively, so that the housing assembly 10 is in the locked state. The second housing 14 of the electronic device 100 in the locked state cannot slide relative to the first housing 12 under normal conditions, that is, the first housing 12 and the second housing 14 of the electronic device 100 in the locked state may be regarded as a whole, when one of the first housing 12 and the second housing 14 is impacted, for example, accidentally dropped, the impact force may be smoothly transmitted to the other of the first housing 12 and the second housing 14, so as to prevent the impact force from damaging the related components of the driving mechanism 60, and protect the related components of the driving mechanism 60.

It will be appreciated that the engagement of telescoping member 73 with slot 14a is exemplary. In other embodiments, the clamping groove 14a is not necessary, for example, the second housing 14 may be provided with an electromagnet at a predetermined position, for example, the first position, the second position, or a position between the first position and the second position, and the telescopic member 73 is made of a ferromagnetic material, for example, iron, cobalt, nickel, or an alloy of this type. When the driving member 71 is in the preset position, the driving member 71 is energized to drive the telescopic member 73 to extend towards the electromagnet and to attract the two members, so that the positions of the first housing 12 and the second housing 14 are relatively fixed. This embodiment can also achieve a locked state of the preset position, and will not be described here again.

In some implementations, the electronic device 100 may include a position sensor (not shown) communicatively coupled to the processor, the position sensor not being limited to a photoelectric sensor, a hall sensor, or the like. The position sensor is disposed in a preset position, such as the clamping groove 14a, and the position sensor is configured to detect a relative position between the telescopic member 73 and the clamping groove 14a, and the processor may be configured to determine whether the telescopic member 73 moves to the preset position, such as the clamping groove 14a, and when the telescopic member 73 moves to the preset position, such as the clamping groove 14a, the control circuit of the driving member 71 is turned on, and the telescopic member 73 is driven to extend into the clamping groove 14a, so that the housing assembly 10 is in a locked state. The position sensor can improve the limit accuracy of the second housing 14 on the first housing 12, so that the housing assembly 10 can be accurately locked at a preset position.

In some embodiments, the clamping grooves 14a are more than two, and the clamping grooves 14a are arranged at intervals along the sliding direction of the second housing 14 relative to the first housing 12. In the unfolded state, the telescopic member 73 moves toward the clamping groove 14a and extends into one of the clamping grooves 14a, as shown in fig. 10, so that the electronic device 100 is locked in the unfolded state. In the process of switching the shell assembly 10 between the unfolded state and the folded state, the driving member 71 is further used for powering on to drive the telescopic member 73 to extend into any other clamping groove 14a, so that the positions of the first shell 12 and the second shell 14 are relatively fixed. In other words, in such an embodiment, there may be more than one intermediate position between the first and second positions, which may be determined by the position of the slot 14 a. When the user needs to lock the second housing 14 at a preset position between the first position and the second position, the processor may control the driving member 71 to be energized to drive the telescopic member 73 to extend into a certain clamping groove 14a between the first position and the second position, so as to lock the electronic device 100 at a certain state between the unfolded state and the folded state.

Illustratively, in the embodiment shown in fig. 8, the second housing 14 is provided with 4 clamping grooves 14a, which may correspond to 4 preset positions. For example, in the moving direction of the second housing 14 relative to the first housing 12, the card slot 14a closest to the guide 30 is used to lock the electronic device 100 in the folded state; the card slot 14a furthest from the guide 30 is used to lock the electronic device 100 in the deployed state; the remaining two clamping grooves 14a are used for locking the electronic device 100 in a certain two states between the unfolded state and the folded state, so that the application scene of the electronic device 100 is wider.

In some embodiments, the locking mechanism 70 is provided in two, and the two locking mechanisms 70 are arranged on opposite sides of the connecting rod 65 in a direction perpendicular to the sliding direction of the second housing 14 relative to the first housing 12. In a sliding direction perpendicular to the second housing 14 and opposite to the first housing 12, opposite ends of the first housing 12 are respectively provided with a clamping groove 14a corresponding to each other in position for locking the electronic device 100 at a preset position. In this embodiment, when the two locking mechanisms 70 lock the electronic device 100 in the preset position, the second housing 14 is more reliable in the limit of the first housing 12 than the single locking mechanism 70, so that the relevant parts of the driving mechanism 60 can be more effectively protected, and the shock resistance of the electronic device 100 is improved.

Referring to fig. 11 and 12, the driving member 71 may include a motor 711, a screw 713, and a slider 715, the motor 711 is connected to the first housing 12, the screw 713 is coupled to an output end of the motor 711, and the slider 715 is coupled to the screw 713 and the expansion member 73. The motor 711 may be a stepper motor 711, or a combination of the stepper motor 711 and a reduction gear set. When the motor 711 is electrified and works, the screw rod 713 can be driven to rotate, the screw rod 713 can be in threaded transmission with the sliding block 715, and the sliding block 715 is driven to move along the length direction of the screw rod 713 so as to drive the telescopic piece 73 to move in a telescopic manner.

In some embodiments, the processor may be further configured to receive a trigger signal to control the motor 711 to drive the telescopic member 73 out of the slot 14a, i.e. drive the telescopic member 73 to move toward the motor 711, as shown in fig. 13, so that the second housing 14 can slide relative to the first housing 12. The trigger signal may be generated by a touch screen operation of the user, for example, the user touches a virtual key to generate the trigger signal, and the processor responds to the trigger signal and controls the motor 711 to operate, thereby releasing the locking state of the electronic device 100. The trigger signal may also be generated by a user pressing a physical key, for example, the first housing 12 or the second housing 14 of the housing assembly 10 may be provided with a physical key for generating the trigger signal to unlock the electronic device 100. Of course, the trigger signal may also be generated by other means, such as a voice control, which will not be described herein.

With continued reference to fig. 11 and 12, in some embodiments, the locking mechanism 70 may further include a bumper 75, the bumper 75 not being limited to a spring, a leaf spring, or a resilient post, or the like. The buffer member 75 is connected to the output ends of the telescopic member 73 and the driving member 71, and in the unfolded state, the output end of the driving member 71 is used for pressing the buffer member 75 so as to drive the telescopic member 73 to be engaged with the second housing 14 through the buffer member 75. The buffer member 75 can realize the elastic contact between the expansion member 73 and the second housing 14, i.e. avoid the expansion member 73 directly striking the second housing 14 to impact the relevant moving parts of the driving member 71, so as to protect the relevant moving parts of the driving member 71 and ensure the service life and the working reliability of the relevant moving parts of the driving member 71.

In the electronic device 100, the locking mechanism 70 is provided in the case assembly 10 and is at least used for energizing in the unfolded state to lock the case assembly 10 in the unfolded state. When the case assembly 10 is locked in the unfolded state, the case assembly 10 in the unfolded state can absorb the impact force and maintain the unfolded state after being impacted, such as accidentally dropped, and prevent the related moving parts from generating large relative movement to protect the moving parts, thereby improving the shock resistance of the electronic device 100.
