technical field

The present application belongs to the technical field of communication equipment, and in particular relates to an electronic equipment.

Background technique

With the development of technology, the use of folding screen electronic devices is increasing.

In order to improve the experience of opening and closing, usually, the two shells of the folding screen electronic device are attracted together by a magnetic attraction, and the two shells are directly separated by external force to realize the unfolding of the display screen. Since the two shells are directly separated by external force, a large external force is required, and the sudden change of force on the folding screen electronic device will damage the folding screen electronic device. Therefore, in the related art, the motor and the transmission assembly are used to drive one of the magnetic attractors away from the other magnetic attractor. During the movement of the magnetic attractors, the attractive force between the two magnetic attractors gradually decreases, realizing two screens. The separation can avoid the problem of sudden change of force. But at the same time, the motor and transmission components will occupy a large space inside the folding screen electronic device.

Contents of the invention

The purpose of the embodiments of the present application is to provide an electronic device, which can solve the problem in the related art that the electronic device with a folding screen occupies a large space.

An embodiment of the present application provides an electronic device, including a first housing, a second housing, and an unfolding mechanism, wherein:

The first housing and the second housing are relatively rotatable;

The deployment mechanism is arranged on the first casing, the deployment mechanism includes a deformation assembly and a driven part, the deformation assembly can be deformed, and the driven part is along a first direction relative to the first casing movable, the first direction intersects the plane where the first casing is located;

The electronic device has a folded state and an unfolded state, and when the electronic device is in the folded state and the deformation component drives the driven part to move along the first direction, the driven part acts on the second casing, so that the electronic device is switched from the folded state to the unfolded state.

In the embodiment of the present application, during the unfolding process of the electronic device, as the degree of deformation of the deformation component increases, the stroke of the driven component driven by the deformation component also gradually increases. Then, along with the movement of the driven component, the force exerted by the driven component on the second casing gradually increases until the first casing and the second casing are separated.

At the same time, using the expansion mechanism to replace the motor and transmission assembly, because the internal structure of the motor itself is relatively complicated, and the motor needs to be connected with the transmission assembly through a specific structure, resulting in a large overall space occupied by the motor and transmission assembly; After the deformation component and the driven part are formed, the deformation component only needs to be able to deform and drive the driven part to move. Therefore, the deformation component can adopt a simple structure that can deform, such as a metal sheet, and the driven part can adopt a simple structure such as a block structure. It only needs to be able to act on the second housing according to the deformation of the deformation component. Therefore, compared with the motor and the transmission component, the space occupied by the deformation component and the driven component is smaller, which reduces the occupied space inside the electronic device.

The following will clearly describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

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

Please refer to FIGS. 1-4 , the electronic device disclosed in the embodiment of the present application includes a first housing 100 , a second housing 200 and an unfolding mechanism. Wherein, the first casing 100 and the second casing 200 can rotate relatively, With the relative rotation of the first casing 100 and the second casing 200, the electronic device switches between the folded state and the unfolded state. Specifically, during the unfolding of the electronic device, at least part of the first housing 100 and the second housing 200 are away from each other; during the folding of the electronic device, at least part of the first housing 100 and the second housing 200 close to each other.

In one solution, the electronic device has a folded state and an unfolded state. When the electronic device is in the folded state, the first casing 100 and the second casing 200 can be attached to each other in areas where they can be separated; when the electronic device is in the unfolded state In this case, the first case 100 and the second case 200 can be separated in a region where they can be separated from each other. The unfolding mechanism is used to drive the detachable areas of the first housing 100 and the second housing 200 away from each other, so that the electronic device is switched from the folded state to the unfolded state.

The deployment mechanism is arranged in the first casing 100, and the deployment mechanism includes a deformation assembly and a driven part 340, wherein the deformation assembly and the driven part 340 can be both arranged inside the first casing 100, or partly located in the first casing 100's outside. The deformation component can be deformed. Specifically, the deformation component can be a stretchable part, or it can be deformed according to temperature change, it can also be electro-induced deformation, or it can be deformed by other factors.

The driven part 340 is movable in a first direction relative to the first casing 100, and the first direction intersects the plane where the first casing 100 is located. The driven part 340 can be in direct contact with the deformation assembly. When the deformation assembly is deformed, The deformation assembly drives the driven part 340 to move along the first direction.

When the electronic device is in the folded state, and the deformation component is deformed to drive the driven part 340 to move in the first direction, the driven part 340 acts on the second casing 200, so that the electronic device can be switched from the folded state to the unfolded state. state. As the deformation degree of the deformation assembly increases, the moving distance of the driven part 340 gradually increases, and the force exerted by the driven part 340 on the second housing 200 also gradually increases until the first housing 100 and the second housing 200 can Areas that are separate from each other are separated.

In this way, the motor and the transmission assembly are replaced by the deployment mechanism. Since the internal structure of the motor itself is relatively complicated, and the motor needs to be connected with the transmission assembly through a specific structure, the overall space occupied by the motor and transmission assembly is relatively large, and the replacement After the deformation assembly and the driven part 340 are formed, the deformation assembly only needs to be able to deform and drive the driven part 340 to move, so the deformation assembly can adopt a simple structure that can deform, such as a metal sheet, and the driven part 340 can also adopt a block structure. Simple structure such as structure, can act on the second housing 200 according to the deformation of the deformation component. Therefore, compared with the motor and the transmission component, the space occupied by the deformation component and the driven part 340 is smaller, reducing the internal space of the electronic device. take up space.

In an optional embodiment, the electronic device further includes a display screen disposed on at least one of the first casing 100 and the second casing 200 . Specifically, the display screen can be arranged on the surface of the first casing 100, or on the surface of the second casing 200, or on the surface of the first casing 100 and the surface of the second casing 200. In this case Next, the display screen includes a first part and a second part, the first part is correspondingly disposed on the surface of the first housing 100 , and the second part is correspondingly disposed on the surface of the second housing 200 .

In an optional embodiment, as shown in FIGS. 2-4 , the deformation assembly includes a deformation element 320 and a wedge 330 , and the deformation element 320 is connected to the wedge 330 . Wherein, the deformation element 320 and the wedge 330 can be directly fixedly connected by means of bonding or the like, or can be connected indirectly. The wedge 330 has a first wedge surface 331, and the first wedge surface 331 is in contact with the driven part 340. When the deformation element 320 is deformed, the wedge 330 is driven to move in the second direction. When the wedge 330 moves, the first wedge 330 of the wedge 330 The wedge surface 331 drives the driven part 340 to move along the first direction. Wherein, the second direction intersects with the first direction. In this embodiment, the second direction is perpendicular to the first direction. It should be noted that the second direction refers to the direction in which the wedge 330 moves under the driving action of the deformation element 320 , which is a single direction.

Moreover, when the electronic device is in the folded state, along the second direction, the distance from the first wedge surface 331 to the second casing 200 increases gradually. Wherein, the second direction can be the X direction in FIG. 2, and can also have a preset angle with the X direction in FIG. 2, and the range of the preset angle can be greater than 0 degrees and less than 90 degrees; The planes where the first housing 100 is located are perpendicular to each other, and may not be perpendicular to the plane where the first housing 100 is located.

In this embodiment, the first direction is perpendicular to the plane where the first housing 100 is located, and the second direction is parallel to the plane where the first housing 100 is located.

Specifically, along the second direction, the distance from the first wedge surface 331 to the second housing 200 can be uniformly increased. In this case, the first wedge surface 331 can be a plane; along the second direction, the distance from the first wedge surface 331 to the second The distance between the two shells 200 can be increased unevenly, in this case, the first wedge surface 331 can be concave The arc surface or the convex arc surface can be used as long as the wedge block 330 can drive the driven part 340 to move along the first direction when the wedge block 330 moves.

Certainly, in other embodiments, the deformation component may include a deformation element 320 , the deformation element 320 is in contact with the driven part 340 , and the deformation element 320 directly drives the driven part 340 to move when deformed.

In such a configuration, the first wedge surface 331 guides the relative movement direction of the wedge block 330 and the driven part 340 through the guiding function of the first wedge surface 331 , so that the driven part 340 moves along the first direction.

Optionally, as shown in FIGS. 2-4 , the driven part 340 has a second wedge surface, and the second wedge surface fits with the first wedge surface 331 and cooperates with each other. Specifically, when the first wedge surface 331 is a plane, the second wedge surface is also a plane; when the first wedge surface 331 is a concave arc surface, the second wedge surface is a convex arc surface; When the first wedge surface 331 is a convex arc surface, the second wedge surface is a concave arc surface. In this embodiment, the first wedge surface 331 and the second wedge surface are both planes, and there is an included angle between the first wedge surface 331 and the plane where the first housing 100 is located, and the range of the included angle is greater than 0 degrees and less than 90 degrees. .

Of course, in other embodiments, the driven part 340 can be provided with a second wedge surface, and the wedge 330 is not provided with the first wedge surface 331. Under the guidance of the second wedge surface, the wedge 330 and the driven part can also be aligned. The relative movement direction of 340 is guided to realize the movement of the driven part 340 along the first direction.

Such arrangement ensures that the relative movement direction of the wedge 330 and the driven part 340 is unique through the cooperation of the second wedge surface and the first wedge surface 331. When the wedge 330 moves along the second direction, the driven part 340 is stable and stable. Move exactly in the first direction.

In this embodiment, along the X direction in FIG. 2 , the first housing 100 has a first end and a second end. The first end is the end where the rotation axis is located. The distance from the moving part 340 to the second end. In this way, according to the force arm principle, the driven part 340 can act on the second housing 200 with a relatively large force only by a small moving distance along the first direction. The first housing 100 and the second housing 100 200 easy to separate.

In order to ensure that the electronic device can be switched to the folded state again, it is necessary to restore the driven part 340 to its original position. In the case that the deforming element 320 or the wedge 330 can be touched manually, the deforming element 320 or the wedge 330 can be manually operated. The variable element 320 is reset. However, the recovery time of manual action is long and the efficiency is low.

In order to solve the above problems, the electronic device further includes a driving mechanism, which is disposed on the first housing 100 and can drive the deformation element 320 to recover the deformation. Specifically, the driving mechanism can be arranged inside the first housing 100 or outside the first housing 100, and the driving mechanism can be a linear drive such as an air cylinder or a linear drive, or other types of driving actuators. It only needs to be able to drive the deformation element 320 to return to its original shape.

In this embodiment, when the deformation element 320 recovers its deformation, the deformation element 320 drives the wedge 330 to reset, so the driven part 340 loses the force exerted by the wedge 330 on it, and the driven part 340 no longer acts on the second housing 200, and can reset along the first wedge surface 331.

Of course, when the deformation element 320 is fixedly connected to the wedge 330 , the driving mechanism can act on the wedge 330 to drive the wedge 330 to reset, and when the wedge 330 resets, it drives the deformation element 320 to return to its original shape.

In this way, the deformation element 320 is driven by the driving mechanism to restore the deformation, so that both the wedge 330 and the driven part 340 can be reset, and the first housing 100 and the second housing 200 can be attached again, so that the electronic device can be in the folded state and Toggle between expanded states.

In an optional embodiment, the driving mechanism includes an elastic member 400 disposed between the deformation element 320 and the first housing 100 . Wherein, when the deformation element 320 is deformed, the area of the elastic member 400 between the first housing 100 and the deformation element 320 is stretched or compressed, that is, the elastic member 400 is elastically deformed; In case of loss of deformation power, the elastic member 400 resumes elastic deformation and drives the deformation element 320 to resume deformation. Specifically, when the deformation element 320 is a temperature-sensitive deformation element, the deformation power refers to the heating power of the heating element 310 to the temperature-sensitive deformation element; The electric field force on the component. In this embodiment, the elastic member 400 may be a spring, of course, other types of elastic members 400 may also be used.

Specifically, as shown in FIGS. 2-4 , the first end of the spring is fixed relative to the first housing 100 , and the second end of the spring is fixed relative to the deformation element 320 . Wherein, the first end of the spring can be connected with the first shell 100 through the transition piece, that is, the transition piece is connected with the first shell 100, and the first end of the spring is connected with the transition piece connected; the second end of the spring can be directly connected to the deformation element 320, and can also be indirectly connected to the deformation element 320. Moreover, the first end of the spring and the transition piece, and the second end of the spring and the deformation element 320 may be fixedly connected by bonding, welding or the like.

When the deformation element 320 is deformed toward the direction of the spring, the area of the spring located between the first housing 100 and the deformation element 320 is compressed; The region between the first housing 100 and the deformation element 320 is stretched.

With this arrangement, the elastic potential energy of the elastic member 400 is used as the driving force, and no electric, pneumatic or manual power source is needed, which saves more energy and is simple and convenient to implement.

In the solution of the present application, as shown in FIGS. 2-4 , the driving mechanism further includes a flexible connection part 500 , and the flexible connection part 500 is arranged between the elastic part 400 and the deformation element 320 . A first end of the flexible connecting member 500 is connected to the elastic member 400 , a second end of the flexible connecting member 500 is connected to the deformation element 320 , and the wedge 330 is connected to the flexible connecting member 500 . Wherein, the wedge 330 can be connected with the middle position of the flexible connector 500, the first end of the flexible connector 500 can be fixedly connected with the end of the spring by bonding or the like, and the second end of the flexible connector 500 can be connected with the end of the spring. The surface of the deformation element 320 may also be fixedly connected by means of bonding or the like.

In this embodiment, the flexible connecting member 500 may be a connecting rope. When the deformation element 320 is deformed, the area of the elastic member 400 between the first housing 100 and the flexible connecting member 500 is stretched, and the deformation element 320 is deformed away from the spring.

Specifically, the wedge 330 and the connecting rope can be connected by bonding, clamping connection, etc., or a through hole can be opened on the wedge 330, and the axis direction of the through hole can be the second direction, that is, the wedge 330 The moving direction of the connecting rope runs through the through hole of the wedge 330, and glue is injected between the connecting rope and the wall of the through hole, thereby increasing the connection area between the connecting rope and the wedge 330.

In such a setting, since the wedge 330 is a three-dimensional structure, it is inconvenient to be directly connected to the deformation element 320. The connecting rope avoids the direct connection between the wedge 330 and the deformation element 320, reduces the area where the deformation element 320 participates in the connection, and ensures the overall connection stability. sex.

Optionally, the deformation element 320 may be a temperature-sensitive deformation element or an electro-deformation element. In the case that the deformation element 320 is a temperature-sensitive deformation element, the deformation assembly may also include a heating element 310, which heats The element 310 is used to heat the temperature-sensitive deformation element. Wherein, the heating element 310 can be an electric heating wire made of metal, or a non-metallic electric heating element such as silicon carbide, electric heating paint, etc., and realizes heating function under the condition of electrification; the temperature sensing deformation element can be a temperature sensing sheet, or other random The element that deforms due to temperature changes only needs to be able to drive the driven member 340 to move in the first direction while being deformed.

For the heating timing of the heating element 310, a button 700 can be set on the first casing 100 or the second casing 200, and whether the heating element 310 is energized is controlled by the pressing state of the button 700; of course, other methods can also be used, such as setting The touch sensor switch is used to control whether the heating element 310 is energized or not.

In an optional embodiment, as shown in FIG. 1 , the electronic device further includes a button 700, which is arranged on the first casing 100 or the second casing 200. When the button 700 is in a pressed state, the deformation element 320 deformed. Optionally, the button 700 may be directly connected to the deformation element 320 , and the movement of the button 700 can directly drive the deformation element 320 to deform.

In this embodiment, the deformation element 320 is a temperature-sensitive deformation element, and the button 700 controls whether the heating element 310 is energized and heated. The wedge 330 moves, thereby driving the driven part 340 to move. Specifically, a circuit board is usually installed inside the electronic device, and the heating element 310 is electrically connected to the circuit board, so that the circuit board supplies power to the heating element 310, and the button 700 controls the electrical connection and disconnection between the heating element 310 and the circuit board. open.

With this configuration, the user can press the button 700 according to his own needs, and realize the unfolding of the electronic device by using the principle of temperature-sensitive deformation.

Of course, when the deformation element 320 is an electro-deformation element, the key 700 controls whether the electro-deformation element is energized, and when the key 700 is in a pressed state, the electro-deformation element deforms when it is energized.

In the technical solution of the present application, the deformation element 320 can be a temperature-sensing sheet. Along the third direction, both ends of the temperature-sensing sheet are connected to the inner wall of the first housing 100 to improve the connection stability of the temperature-sensing sheet. The direction is perpendicular to the plane where the first housing 100 is located. It should be noted that the third direction is the Y direction in FIG. 2 . When the temperature-sensing sheet is not heated, the temperature-sensing sheet has a planar structure; when the temperature-sensing sheet is heated, the temperature-sensing sheet is deformed into an arched structure, as shown in Figure 3.

In this embodiment, the temperature sensing element may be a bimetallic temperature sensing element. Specifically, the end of the temperature sensing element may be connected to the inner wall of the first housing 100 by bonding, welding or the like. Certainly, in other embodiments, one end of the temperature sensing sheet may be connected to the inner wall of the first housing 100 , and the flexible connecting member 500 may be connected to the other end of the temperature sensing sheet or other positions.

Optionally, the deformation element 320 has multiple deformation points, and among each deformation point, the deformation point with the largest deformation amount is connected to the wedge 330 . It can be seen from Figure 3 that when the temperature-sensing sheet becomes an arched structure, the deformation of the arched structure is the largest in the middle position, and the deformation of the arched structure gradually increases in the direction from the middle position of the arched structure to the end of the arched structure. decrease. Specifically, the end of the flexible connector 500 can be connected to the middle position of the arch structure, or can be connected to other positions of the arch structure.

In this embodiment, the end of the flexible connector 500 is connected to the middle of the arch structure.

In this way, during the deformation process of the deformation element 320, the movement stroke of the wedge 330 and the driven part 340 is relatively large, which can make the force of the driven part 340 acting on the second housing 200 change greatly, thereby ensuring the first There is enough variation between the housing 100 and the second housing 200 to realize the separation of at least partial areas of the first housing 100 and the second housing 200 .

In the technical solution of the present application, the driven part 340 has an active surface 341 for contacting the second housing 200 , and the active surface 341 is an arc surface. Certainly, in other embodiments, the active surface 341 may also be a plane or an active surface 341 with other structures.

In this way, since the arc surface itself is relatively smooth and the force is uniform, when the arc surface acts on the second housing 200, the stress difference at each position of the contact surface between the second housing 200 and the driven part 340 is small, The stress change is relatively uniform, so as to avoid the damage of the second shell 200 caused by the excessive stress difference of the contact surface.

In an optional embodiment, the first housing 100 is provided with an opening 120, and the driven part 340 is movably disposed at the opening 120. In this embodiment, the opening 120 is opened on the first housing 100 facing On the surface of the second housing 200 , the driven part 340 can protrude from the opening 120 and act on the second housing 200 . Moreover, an elastic film is provided at the opening 120, and the elastic film closes the opening 120, and the driven part 340 pushes the second casing 200 by pushing the elastic film. Wherein, the elastic film may be fixed around the opening 120 by means of bonding or the like. Specifically, the elastic film may be a thin film made of materials with elastic properties such as rubber or silica gel.

In this way, the opening 120 is closed by the elastic film, so that the electronic equipment is waterproof and dustproof, and foreign matter is prevented from entering the first housing 100 through the opening 120; moreover, since the elastic film has elastic properties, the elastic film will not affect the The driving part 340 protrudes out of the opening 120 so as not to hinder the force application between the driven part 340 and the second housing 200. It should be noted that, in this case, there is a gap between the driven part 340 and the second housing 200. The elastic film, the driven part 340 is indirectly matched with the second housing 200 .

Optionally, the first housing 100 is provided with a guiding mechanism, the guiding direction of the guiding mechanism is the first direction, and under the guiding action of the guiding mechanism, the driven part 340 can move along the first direction. Specifically, the guide mechanism can be a guide rail, and the guide rail can be a guide groove or a guide hole. The driven part 340 stretches into the guide groove or the guide hole, and the outer surface of the driven part 340 can be aligned with the groove wall surface of the guide groove. Or the inner wall of the guide hole to match.

In such a configuration, the guide mechanism provides guidance to the moving direction of the driven part 340 to ensure that the driven part 340 moves accurately along the first direction.

In an optional embodiment, as shown in FIGS. 2-4 , the electronic device further includes a first magnetic attraction 110 and a second magnetic attraction 210. The two magnetic components 210 are disposed on the second casing 200 , and the first magnetic component 110 and the second magnetic component 210 can be attracted to each other. In this embodiment, the first magnetic attraction 110 and the second magnetic attraction 210 are heteropolar magnets, the first magnetic attraction 110 is arranged inside the first housing 100, and the second magnetic attraction 210 is arranged in the second The interior of the casing 200 prevents the first magnetic attraction part 110 and the second magnetic attraction part 210 from being exposed and affecting the use of the electronic device.

Specifically, when the force of the driven part 340 is increased to be equal to the force of attraction between the first magnetic component 110 and the second magnetic component 210 , the force between the first housing 100 and the second housing 200 The suction force is zero, and the first housing 100 and the second housing 200 can be directly separated at this time; when the force of the driven part 340 increases to be greater than the When the suction force is applied, the second housing 200 actively moves away from the first housing 100 .

Of course, in other embodiments, the first magnetic member 110 and the second magnetic member 210 can be replaced by damping hinges, the driven part 340 acts on the second housing 200, and the first housing 100 and the second housing When the body 200 is separated to a certain extent, the first casing 100 and the second casing 200 will automatically move away from each other to achieve complete deployment.

In this way, the first housing 100 and the second housing 200 are attracted to each other through the first magnetic member 110 and the second magnetic member 210, so as to ensure the stability of the electronic device in the folded state and avoid accidents caused by accidents. The first case 100 and the second case 200 are separated.

In the technical solution of the present application, the electronic device also includes a temperature detection element 600 and a heating element 310. The heating element 310 is used to heat the deformation element 320. At this time, the deformation element 320 is a temperature-sensitive deformation element, and the temperature detection element 600 is used to detect heating. The heating temperature of the element 310 , the heating element 310 and the temperature detection element 600 are both set in the first casing 100 , and the temperature detection element 600 and the heating element 310 are communicably connected.
