Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Alternatively, as shown in fig. 1 to 7, an embodiment of the present application provides an electronic device including a housing 100, a screen 200, a temperature detection element 300, and a limiting mechanism 500.

The housing 100 is a basic mounting member of the electronic device, which can provide a mounting base for components such as the screen 200, a main board, and a battery. In order to improve the user experience and meet different requirements of the user, the electronic device may change the size of the screen 200, wherein the electronic device may be a foldable electronic device or a retractable electronic device. Based on this, the housing 100 includes a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 can move relatively. For example, the first housing 110 and the second housing 120 may be folded with respect to each other, or the first housing 110 and the second housing 120 may be extended and retracted with respect to each other, so that the size and shape of the casing 100 may be changed.

The screen 200 is a display and control member of the electronic device, and a user can watch videos, pictures and the like through the screen 200 and can also control the electronic device by operating the screen 200. The screen 200 is disposed on the casing 100, and the screen 200 can be deformed along with the relative movement of the first casing 110 and the second casing 120. Specifically, when the first casing 110 and the second casing 120 are folded relatively, the screen 200 is also folded accordingly, and when the first casing 110 and the second casing 120 are relatively extended and retracted, the screen 200 is also extended and retracted accordingly. Based on this, it is possible to satisfy different demands of the user by changing the size of the screen 200. When a user plays a game or watches a movie, the first shell 110 and the second shell 120 can be relatively unfolded, and at the moment, the screen 200 is also unfolded to form a larger screen 200, so that the user can conveniently operate and watch the screen, and the user experience is improved. When the user carries or operates with one hand, the first casing 110 and the second casing 120 can be folded relatively, and at this time, the screen 200 is also folded to form a smaller screen 200, which is convenient for the user to carry and operate with one hand.

In consideration of the problem that the screen 200 is easily damaged by deformation in a low-temperature environment, the temperature detection element 300 is provided in the electronic device in the embodiment of the present application, and the temperature detection element 300 is provided in a region adjacent to the screen 200. The temperature detecting element 300 is in direct contact with the screen 200, or the temperature detecting element 300 is spaced from the screen 200 by a small distance. As such, the temperature of the screen 200 can be detected in real time by the temperature detecting element 300. Alternatively, the temperature detecting element 300 may be a temperature sensor, and of course, may also be other components having a function of detecting temperature.

In order to prevent the screen 200 from deforming in a low-temperature environment, the limiting mechanism 500 is additionally arranged in the embodiment of the present application, and the limiting mechanism 500 can limit the relative movement between the first casing 110 and the second casing 120, so that the screen 200 can be effectively prevented from deforming in the low-temperature environment. Here, the limiting mechanism 500 may be electrically connected to the temperature detecting element 300, and of course, the limiting mechanism 500 may also be electrically connected to the circuit board 800 of the electronic device. When the temperature detecting element 300 detects that the temperature of the screen 200 is lower than a preset value (e.g., -15 ℃), a signal may be sent to the limiting mechanism 500 to limit the relative movement of the first casing 110 and the second casing 120 by the limiting mechanism 500. It should be noted that the limiting mechanism 500 may generate a force opposite to the force applied by the user to change the shape of the screen 200, that is, when the user attempts to change the shape of the screen 200, the limiting mechanism 500 may limit the first casing 110 and the second casing 120, so that the user cannot change the shape of the screen 200, thereby reducing the risk of damage caused by deformation of the screen 200 in a low-temperature environment. In addition, the specific structure of the limiting mechanism 500 and the limiting principle of the limiting mechanism 500 will be described in detail later in the embodiments of the present application.

In the embodiment of the present application, when the user has a requirement for changing the size of the screen 200, and the temperature of the screen 200 detected by the temperature detecting element 300 is not lower than the preset value, the user can normally operate the electronic device to move the first casing 110 and the second casing 120 relatively, so as to change the shape and size of the screen 200. When the temperature of the screen 200 detected by the temperature detecting element 300 is lower than the preset value, the limiting mechanism 500 acts and limits the relative movement of the first casing 110 and the second casing 120 to prevent the screen 200 from changing its shape along with the relative movement of the first casing 110 and the second casing 120, so that the screen 200 maintains its current shape.

Based on the above arrangement, under the low temperature environment, the risk that the screen 200 is folded or unfolded to be damaged is reduced, and the screen 200 is prevented from being damaged, so that the electronic equipment is more humanized, meets the ergonomics, and improves the perception value of the user.

Optionally, the screen 200 includes a main screen 210 and a sub-screen 220, and a user may view or operate the electronic device through the main screen 210 when the screen 200 is in an expanded state, or view or operate the electronic device through the sub-screen 220 when the screen 200 is in a collapsed state.

In order to prevent the user from changing the form of the screen 200 in a low temperature environment, the user may be reminded by sending a reminder message through the screen 200. Specifically, when the temperature detection element 300 detects that the temperature of the screen 200 is lower than a preset value, if the screen 200 is in the expanded state at this time, a prompt message pops up on the main screen 210; if the screen 200 is in the closed state, a reminder message pops up on the sub-screen 220.

As shown in FIG. 1, a status bar 230 is disposed at the top of the main screen 210, and some status information of the electronic device can be presented to the user through the status bar 230. In a normal state, the temperature of the screen 200 detected by the temperature detecting element 300 can be displayed on the status bar 230 in real time for the user to view, and when the temperature of the screen 200 detected by the temperature detecting element 300 is lower than a preset value, a reminding message pops up in the status bar 230 on the main screen 210 in a window form to remind the user that the form of the screen 200 should not be changed.

As shown in FIG. 2, a status bar 230 is disposed at the top of the secondary screen 220, and some status information of the electronic device can be presented to the user through the status bar 230. In a normal state, the temperature of the screen 200 detected by the temperature detecting element 300 can be displayed on the status bar 230 in real time for the user to view. When the temperature of the screen 200 detected by the temperature detecting element 300 is lower than the preset value, a reminding message pops up in the status bar 230 of the sub-screen 220 in the form of a window to remind the user that the form of the screen 200 should not be changed.

Based on the above setting, the status bar 230 can be used for feeding back the reminding information to the user, so as to remind the user, reduce the risk of damage caused by the change of the screen 200 in the low-temperature environment, and further ensure the normal use of the screen 200.

Optionally, as shown in fig. 4 and 5, the electronic device further includes a position detection component electrically connected to the circuit board 800 of the electronic device, and the relative position of the first casing 110 and the second casing 120 can be detected in real time through the position detection component. In some embodiments, the position detecting assembly may include a magnetic member 410 and a hall sensor 420, the magnetic member 410 being disposed on one of the first housing 110 and the second housing 120, and the hall sensor 420 being disposed on the other of the first housing 110 and the second housing 120. The magnetic member 410 may be disposed on the first housing 110 and the hall sensor 420 may be disposed on the second housing 120, or the magnetic member 410 may be disposed on the second housing 120 and the hall sensor 420 may be disposed on the first housing 110. For example, the hall sensor 420 may detect a magnetic field of the magnetic member 410, and when a distance between the magnetic member 410 and the hall sensor 420 changes, the magnetic field of the magnetic member 410 detected by the hall sensor 420 changes, so as to detect a previous relative position of the first casing 110 and the second casing 120. It should be noted that, the working principle of the interaction between the magnetic element 410 and the hall sensor 420 can refer to the related art, and is not described herein again.

In some embodiments, the first casing 110 and the second casing 120 may be connected by a hinge structure 600, so that the first casing 110 and the second casing 120 may be folded relatively, and the hinge structure 600 may include a left rotating shaft and a right rotating shaft, wherein the left rotating shaft is fixed relative to the first casing 110, and the right rotating shaft is fixed relative to the second casing 120. In this way, the position between the magnetic member 410 or the hall sensor 420 provided on the first housing 110 and the left rotation shaft is relatively fixed, and the position between the hall sensor 420 or the magnetic member 410 provided on the second housing 120 and the right rotation shaft is relatively fixed, so that the relative movement between the first housing 110 and the second housing 120 can be reflected by detecting the change in the relative position between the left rotation shaft and the right rotation shaft.

Optionally, the electronic device further comprises a sound producing device, which is electrically connected to the circuit board 800 of the electronic device. When the temperature detecting element 300 detects that the temperature of the screen 200 is lower than the preset value and the position detecting assembly detects that the first casing 110 and the second casing 120 move relatively, the sounding device sends out an alarm reminding message to remind the user. Alternatively, the sound producing device may be a speaker of the electronic device. The alarm reminding information may be: do not unfold the screen 200 or fold the screen 200.

Based on the above arrangement, the user can be reminded in the form of sound that the form of the screen 200 is not suitable to be changed in a low-temperature environment, so as to reduce the risk of damage to the screen 200.

Optionally, the electronic device further comprises a vibration device, which is electrically connected to the circuit board 800 of the electronic device. When the temperature detecting element 300 detects that the temperature of the screen 200 is lower than the preset value and the position detecting assembly detects that the first casing 110 and the second casing 120 generate relative motion, the vibration device sends out a vibration reminding message. So as to play a role of reminding the user. Alternatively, the vibration device may be a vibration motor. The alarm reminding information may be: how many times the vibration is continuous or periodic vibration, etc.

Based on the above arrangement, the user can be reminded in a vibration mode that the form of the screen 200 is not suitable to be changed in a low-temperature environment, so that the risk of damage to the screen 200 is reduced.

Alternatively, the limiting mechanism 500 includes a limiting portion, the limiting portion includes a hinge gear 610, the limiting portion is disposed opposite to the hinge gear 610 and is movable relative to the hinge gear 610, the limiting portion limits the hinge gear 610 to rotate to limit the relative movement of the first casing 110 and the second casing 120 when the limiting portion is engaged with the hinge gear 610, and the limiting portion releases the limitation of the hinge gear 610 to allow the first casing 110 and the second casing 120 to move relative to each other when the limiting portion is separated from the hinge gear 610.

The hinge gear 610 is a structural member of the electronic device for realizing the relative movement between the first housing 110 and the second housing 120, and the hinge gear 610 may be a spur gear, a helical gear, or the like. The specific structure and shape of the hinge gear 610 in the embodiment of the present application are not limited as long as the motion or power can be transmitted between the first housing 110 and the second housing 120. In the foldable electronic device, the first housing 110 and the second housing 120 can be foldably connected through the mutually meshed hinge gears 610, and during the folding process of the first housing 110 and the second housing 120, the mutually meshed hinge gears 610 relatively rotate. In the retractable electronic device, the first housing 110 and the second housing 120 can be telescopically connected by the engaged hinge gear 610 and the rack, and the engaged hinge gear 610 and the rack relatively move during the process of extending and retracting the first housing 110 and the second housing 120.

In order to limit the relative movement between the first casing 110 and the second casing 120, the limiting mechanism 500 is added in the embodiment of the present application, and the limiting portion is engaged with the hinge gear 610 to limit the rotation of the hinge gear 610, so as to limit the relative movement between the first casing 110 and the second casing 120.

As shown in fig. 6, in some embodiments, the limiting mechanism 500 includes a mounting member 510, a fixing member 520, a movable member 530 and a telescopic driving member 540, the fixing member 520 is disposed on the mounting member 510, the telescopic driving member 540 is connected between the fixing member 520 and the movable member 530, the movable member 530 is the limiting portion, and the movable member 530 can be driven by the telescopic driving member 540 to approach the hinge gear 610 along the axial direction of the hinge gear 610, so as to limit the rotation of the hinge gear 610 through the movable member 530, or to be away from the hinge gear 610, so as to release the limitation on the hinge gear 610.

Alternatively, the mounting member 510 may be a metal plate fixed to the rotation shaft 620 of the hinge structure 600, and accordingly, the hinge gear 610 may be fixed to the first housing 110 or the second housing 120, so that the hinge gear 610 may rotate with respect to the metal plate when the first housing 110 or the second housing 120 rotates with respect to the hinge structure 600. The fixed member 520 is fixed to the mounting member 510 such that the fixed member 520 and the movable member 530 are coupled to the fixed member 520 by the telescopic driving member 540, and thus, the movable member 530 and the hinge gear 610 can rotate relatively. The telescopic driving member 540 can drive the movable member 530 to move relative to the fixed member 520 and move the movable member 530 to approach or move away from the hinge gear 610.

When the temperature of the screen 200 is lower than the preset value and the relative movement between the first casing 110 and the second casing 120 needs to be limited, the telescopic driving member 540 drives the movable end to approach and press the end surface of the hinge gear 610, and under the action of friction force, the hinge gear 610 can be limited from rotating relative to the rotating shaft 620, so that the first casing 110 or the second casing 120 cannot rotate relative to the hinge structure 600, and further the first casing 110 and the second casing 120 cannot move relative to each other.

When the temperature of the screen 200 is higher than the preset value, it is not necessary to limit the relative movement between the first casing 110 and the second casing 120, and at this time, the telescopic driving member 540 drives the movable end to be away from the end surface of the hinge gear 610, so that the hinge gear 610 can rotate relative to the rotating shaft 620, and thus the first casing 110 or the second casing 120 can rotate relative to the hinge structure 600, and further the first casing 110 and the second casing 120 can move relative to each other.

Alternatively, the telescopic driving member 540 may be an air cylinder, a hydraulic cylinder, an electric cylinder, or the like, and the embodiment of the present application does not limit the specific form of the telescopic driving member 540 as long as the driving process of the movable member 530 can be achieved.

In order to improve the limiting effect, in the embodiment of the present application, the friction plate 550 is disposed on the side of the movable end opposite to the hinge gear 610, and the friction acting force between the movable member 530 and the hinge gear 610 can be improved through the friction plate 550, so as to ensure the limitation on the hinge gear 610, and further ensure the limiting effect on the deformation of the screen 200 in the low temperature environment, so that the screen 200 is intact.

In other embodiments, as shown in fig. 7, the limiting mechanism 500 comprises a connecting tooth 560, a memory alloy member 570 and an elastic member 580, wherein the memory alloy member 570 is connected to the connecting tooth 560, the memory alloy member 570 can drive the connecting tooth 560 to be separated from the tooth slot 611 of the hinge gear 610, the elastic member 580 is connected to the connecting tooth 560, and the elastic member 580 can drive the connecting tooth 560 to extend into the tooth slot 611 of the hinge gear 610. Specifically, when an electrical signal is input, the memory alloy member 570 can shorten its length, so as to pull the connecting teeth 560 to move, so that the end portions of the connecting teeth 560 are separated from the tooth grooves 611 of the hinge gear 610, the restriction on the hinge gear 610 is removed, and the first housing 110 and the second housing 120 move relative to each other, and at the same time, the connecting teeth 560 press the elastic member 580, so that the elastic member 580 contracts and stores elastic potential energy. On the contrary, the memory alloy 570 can be restored when the electrical signal is interrupted, and at this time, the elastic member 580 stretches and releases the elastic potential energy, and under the elastic force of the elastic member 580, the connecting tooth tip 560 moves towards the hinge gear 610, and the end of the connecting tooth tip 560 extends into the tooth slot 611, so that the limiting effect on the hinge gear 610 is achieved, and the first shell 110 and the second shell 120 cannot move relatively.

Further, the limiting mechanism 500 further includes a sleeve 590, the sleeve 590 has a receiving cavity 591 with an opening at one end, the connecting tooth 560 is movably disposed in the receiving cavity 591, and the connecting tooth 560 is capable of extending or retracting relative to the opening, the memory alloy element 570 and the elastic element 580 are both disposed in the receiving cavity 591, and one end of each of the memory alloy element and the connecting tooth 560 is connected to the connecting tooth 560, the other end of each of the memory alloy element and the elastic element 580 is connected to the bottom end surface of the receiving cavity 591, and the elastic element 580 is sleeved outside the memory alloy element 570. Alternatively, the elastic member 580 may be a spring.

With the above arrangement, the connecting teeth 560 can be guided by the sleeve 590 so that the connecting teeth 560 can be disengaged from the tooth grooves 611 or extend into the tooth grooves 611. Because the elastic member 580 is sleeved on the outer side of the memory alloy member 570, the space occupied by the two members is smaller, and the occupation of the internal space of the electronic device is solved. The movement of the memory alloy 570 and the elastic member 580 can be limited by the accommodation cavity 591, and the stable installation of the memory alloy 570 and the elastic member 580 is ensured.

Optionally, the electronic device includes a hinge structure 600 connected between the first casing 110 and the second casing 120, and the first casing 110 and the second casing 120 can be relatively folded through the hinge structure 600, in this case, the electronic device is a foldable electronic device. In other embodiments, the first housing 110 and the second housing 120 may be slidably connected to each other, so that the first housing 110 and the second housing 120 can be relatively telescopic, and at this time, the electronic device is a telescopic electronic device. It should be noted that, for the specific structure and principle of the first casing 110 and the second casing 120 being folded or extended relatively, reference may be made to the related art, and details are not repeated herein.

Based on the above arrangement, the screen 200 can be folded and deformed along with the relative folding of the first casing 110 and the second casing 120, or can be telescopically deformed along with the relative extension and contraction of the first casing 110 and the second casing 120, so as to meet the requirements of different users.

Alternatively, as shown in fig. 1 and 5, the screen 200 has a bending region 240 disposed opposite to the hinge structure 600, and during the relative folding of the first casing 110 and the second casing 120, the bending region 240 of the screen 200 is bent and deformed to accommodate the relative folding movement of the first casing 110 and the second casing 120. In order to improve the temperature detection accuracy of the screen 200 to ensure that the screen 200 is not damaged at low temperature, in the embodiment of the present application, the temperature detection element 300 is in contact with the bending region 240, so that the temperature of the deformed portion of the screen 200 can be directly detected by the temperature detection element 300, thereby avoiding the problem that the bending region 240 is bent and deformed under a low-temperature environment to cause damage to the screen 200.

Based on the above arrangement, the area of the screen 200 where the deformation occurs can be directly detected by the temperature detection element 300, so that the problem of temperature difference due to different detection positions can be alleviated, and the detection accuracy of the temperature can be further ensured.

Alternatively, as shown in fig. 3, the electronic apparatus further includes a circuit board 800 and a fixing bracket 700 for mounting the screen 200, the fixing bracket 700 is located between the screen 200 and the circuit board 800, and the temperature detecting element 300 is disposed on the circuit board 800 and electrically connected to the circuit board 800. In order to enable the temperature detecting element 300 to contact the screen 200, in the embodiment of the present invention, an avoiding space 710, such as an avoiding hole, is formed on the fixing bracket 700, and at this time, the temperature detecting element 300 may pass through the avoiding space 710 and contact the screen 200, thereby facilitating the temperature detection of the screen 200.

Based on the above arrangement, the temperature detection element 300 can conveniently detect the temperature of the screen 200, so as to prevent the screen 200 from being deformed under the low-temperature environment and causing the damage of the screen 200.

In addition, the temperature detection element 300, the position detection assembly, the limiting mechanism 500, the screen 200, the sound production device, the vibration device, and the like in the embodiment of the present application are all electrically connected to the circuit board 800 of the electronic device, so that the electronic device can be controlled in all directions through the circuit board 800 to meet various requirements.

It should be noted here that the two types of limiting mechanisms 500 can be applied to a foldable electronic device and a retractable electronic device, and the rotation of the hinge gear 610 can be limited by the limiting mechanism 500, so as to limit the relative movement between the first casing 110 and the second casing 120, so as to ensure that the screen 200 cannot change its shape in a low-temperature environment, and further ensure that the screen 200 is intact.

The control logic for realizing low-temperature reminding and limiting the deformation of the screen 200 in the embodiment of the application is as follows:

as shown in fig. 8, the user needs to change the size of the screen 200 according to his or her needs, for example, to unfold the screen 200 or fold the screen 200. The temperature detecting element 300 detects the temperature of the screen 200 in real time and transmits the detection result to the circuit board 800 of the electronic device, the circuit board 800 performs adaptive control according to the temperature of the screen 200, when the temperature of the screen 200 is lower than a preset value (e.g., -15 ℃), the position detecting element detects the state of the housing 100, and if the housing 100 is in a folded state, the circuit board 800 controls the secondary screen 220 to pop out a reminding message: do not fold screen 200; if the housing 100 is in the unfolded state, the circuit board 800 controls the main screen 210 to pop up a reminder message: do not close the screen 200. Meanwhile, the position detecting component learns whether the user has an action of folding or unfolding the housing 100 according to the detection of the relative position of the first housing 110 and the second housing 120, and if the user applies the folding or unfolding action to the housing 100, that is, the first housing 110 and the second housing 120 move relatively, the circuit board 800 controls at least one of the sound generating device and the vibrating device to send out a reminding message: the circuit board 800 controls the limiting mechanism 500 to act, the limiting mechanism 500 limits the relative movement between the first casing 110 and the second casing 120 to deform the casing 100, and at this time, the user cannot deform the casing 100, so that the screen 200 cannot be deformed, thereby limiting the screen 200 from being deformed in a low-temperature environment, and alleviating the problem that the screen 200 is easily damaged due to low-temperature deformation, and if the user does not apply a folding or unfolding action to the casing 100, at least one of the sounding device and the vibrating device does not send out a reminding message. When the temperature of the screen 200 is not lower than a preset value (for example, the preset value is-15 deg.c, and the current temperature is-15 deg.c or higher than-15 deg.c), the user may deform the screen 200 to meet the actual demand.

To sum up, in the embodiment of the application, under the low temperature environment, the risk that the screen 200 is folded or unfolded to be damaged is reduced, and the screen 200 is prevented from being damaged, so that the electronic device is more humanized, meets the ergonomics, and improves the perception value of the user.
