Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is specifically noted that the following examples are only for illustration of the present application, but do not limit the scope of the present application. Likewise, the following embodiments are only some, but not all, of the embodiments of the present application, and all other embodiments obtained by one of ordinary skill in the art without making any inventive effort are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a public-switched telephone network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface, such as for example, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network, such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal. A communication terminal configured to communicate through a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellites or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; a PDA that can include a radiotelephone, pager, internet/intranet access, web browser, organizer, calendar, and/or a Global Positioning System (GPS) receiver; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. The mobile phone is the electronic equipment provided with the cellular communication module.
It should be noted that the electronic device in the embodiments of the present application is mainly directed to an electronic device having a folding screen, for example, a folding screen mobile phone. In particular, the folding screen mobile phone has gradually become the development trend of the whole machine in the future, and has the advantages of entertainment and office, portability and capability of meeting the requirements of consumers on portability and various and unified functions. The folding screen mobile phone generally has folding modes such as inward folding, outward folding and the like. For the folding screen mobile phone in the inward folding mode, after the folding is completed, the display surfaces of the flexible screen are close to each other along the folding area, namely the flexible screen is in the inward folding mode. For the folding screen mobile phone in the outward folding mode, after the folding is completed, the display surfaces of the flexible screen deviate from each other along the folding area, namely the flexible screen is in a folding mode of being folded outwards.
Taking an example of a folding screen mobile phone in an inward folding mode, the flexible screen is generally in a water drop shape after being folded, namely, a water drop type hinge structure is generally adopted to complete the folding of the flexible screen. However, the water drop type hinge structure in the conventional technical scheme is complex, more in cooperation and difficult to control the folding track.
In order to solve the above problems, the technical solution of the present embodiment is to provide a rotating shaft assembly with a simple structure and easy control of a folding track, so as to ensure that the folding track of electronic devices such as a folding screen mobile phone is accurate, and reduce the structural complexity and the cost of the electronic devices.
It should be noted that, the electronic device in the embodiment of the present application is mainly directed to an electronic device with a foldable flexible screen, and the electronic device may be any device with an inward folding manner. For example, the electronic device may be a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, or the like, which is an intelligent device having an invagination system. The electronic device provided by the embodiment of the application is exemplified by a mobile phone folded inwards.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an electronic device 100 according to some embodiments of the present application when the electronic device 100 is opened, and fig. 2 is a schematic structural diagram of the electronic device 100 according to the embodiment of fig. 1 when the electronic device is closed. The electronic device 100 may include a center 10, a spindle assembly 20, and a flexible screen 30. The center 10 is configured to carry a hinge assembly 20 and a flexible screen 30, the hinge assembly 20 being disposed between the center 10 and the flexible screen 30. Further, the middle frame 10 may be folded, that is, the middle frame 10 may exhibit an open state (first state) as shown in fig. 1 and a closed state (second state) as shown in fig. 2 under an external force, so that the electronic device 100 may have an open state and a closed state.
Fig. 1 is a schematic structural diagram of the electronic device 100 when the middle frame 10 is opened (first state), and fig. 2 is a schematic structural diagram of the electronic device 100 when the middle frame 10 is closed (second state). The flexible screen 30 may be folded synchronously with the folding of the middle frame 10.
Specifically, the flexible screen 30 has a folded region 301 and an unfolded region 302 of unitary construction, and the unfolded region 302 is connected to the side edges of the folded region 301. Alternatively, the folded region 301 is located in a central region of the flexible screen 30 and the unfolded region 302 is located on opposite sides of the folded region 301, i.e., the unfolded region 302 may be two. In the first state, the folded region 301 is flattened to a flat shape, and two non-folded regions 302 are located on opposite sides of the folded region 301, so that the flexible screen 30 may assume a flat non-folded state. In the second state, the folding region 301 may be folded in an arc shape, and the two non-folding regions 302 are located on the same side of the folding region 301 and are close to each other, so that the flexible screen 30 may take on a water-drop type folding state.
The flexible screen 30 may be a flexible display screen such as an OLED (Organic Light-Emitting Diode), and has characteristics of flexibility, bending, and the like.
In an embodiment, the middle frame 10 may include a left frame 101 and a right frame 102, where the left frame 101 and the right frame 102 are rotatably connected by the rotating shaft assembly 20, that is, opposite ends of the rotating shaft assembly 20 are respectively connected to the left frame 101 and the right frame 102. When the electronic device 100 is changed from the first state shown in fig. 1 to the second state shown in fig. 2, the left frame 101 and the right frame 102 move toward each other to fold the middle frame 10; when the electronic apparatus 100 is changed from the second state shown in fig. 2 to the first state shown in fig. 1, the left frame 101 and the right frame 102 are moved in opposition to each other so that the middle frame is opened. The flexible screen 30 may be synchronously unfolded or folded as the middle frame 10 is unfolded or folded. Alternatively, the middle frame 10 and the rotating shaft assembly 20 are fixedly connected, i.e., opposite ends of the rotating shaft assembly 20 are fixedly connected to the left frame 101 and the right frame 102, respectively, so that the rotating shaft assembly 20 can be folded in synchronization with the middle frame 10, i.e., maintain a substantially uniform folding angle.
It is understood that the structures of the left frame 101 and the right frame 102 are substantially identical, and in order to avoid repetition of the description, the left frame 101 or the right frame 102 is exemplified as the frame 10 in the following description. For example, the middle frame 10 described below may be the left frame 101 or the right frame 102.
In an embodiment, the middle frame 10 may include a middle plate 110 with an integral structure and a frame 120 extending from an edge of the middle plate 110, that is, the frame 120 surrounds at least a portion of an outer periphery of the middle plate 110, and the middle plate and the frame are integrally formed by injection molding, stamping, heat absorption molding, and the like. The frame 120 may be formed by extending a side wall of the middle plate 110 in a thickness direction of the middle plate 110, so that two opposite sides of the middle frame 10 may form a corresponding open structure. In some embodiments, the middle plate 110 and the frame 120 may also be two independent structural members, and the two structural members may be connected by one of assembling manners such as clamping, bonding, welding, and the like, and a combination thereof.
The middle frame 10 may be made of glass, metal, hard plastic, etc., so that the middle frame 10 has a certain structural strength.
In an embodiment, the middle plate 110 is used for carrying the rotating shaft assembly 20, the frame 120 is used for carrying the flexible screen 30, that is, the rotating shaft assembly 20 may be fixedly connected to the middle plate 100, the flexible screen 30 may be fixedly connected to the frame 120, that is, the flexible screen 30 may cover an open structure on one side of the middle frame 10. Wherein the rotating shaft assembly 20 is disposed between the middle plate 110 and the flexible screen 30. In the second state, the rotating shaft assembly 20 is folded along with the middle frame 10 and can provide a screen accommodating space for the flexible screen 30 to be folded into a water drop shape; in the first state, the hinge assembly 20 is deployed to support a portion of the flexible screen 30.
Referring to fig. 3 to 5, fig. 3 is a schematic diagram of a portion of the electronic device 100 according to some embodiments of the present application, fig. 4 is a schematic diagram of another state of the electronic device 100 according to the embodiment of fig. 3, and fig. 5 is a schematic diagram of a structural separation of the electronic device 100 according to the embodiment of fig. 3. The electronic device 100 in fig. 3 is in the first state, and the electronic device 100 in fig. 4 is in the second state.
Specifically, the rotation shaft assembly 20 may include a first housing 210, a second housing 220, and a first connection member 230 connecting the first housing 210 and the second housing 220. The first base 210 corresponds to the folding area of the flexible screen 30, and the second base 220 is fixedly connected with the middle frame 10. Alternatively, the second base 220 may be fixed on the middle plate of the middle frame 10, the first base 210 may be disposed on a side of the second base 220 away from the frame of the middle frame 10, and the first base 210 and the second base 220 are disposed on a side of the flexible screen 30 close to the middle frame 10, i.e., the first base 210 and the second base 220 are disposed on the same side of the flexible screen 30. It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement conditions, and the like between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is correspondingly changed.
In an embodiment, the first connecting member 230 is rotatably connected to the first base 210, such that the second base 220 can rotate relative to the first base 210 via the first connecting member 230. In other words, the second housing 220 is rotatably coupled to the first housing 210 by the first coupling member 230. Alternatively, the first connecting member 230 may be rotatably connected to the first base 210 by a shaft, a pin, or the like. For example, a groove structure may be disposed on a side of the first base 210 near the second base 220, and one end of the first connecting member 230 connected to the first base 210 may be disposed in the groove structure of the first base 210, and may be rotatably connected to the first base 210 by a structural member such as a rotating shaft or a pin. For another example, a protruding structure may be disposed on a side of the first base 210 near the second base 220, and one end of the first connecting member 230 connected to the first base 210 may be rotatably connected to the protruding structure by a structural member such as a rotating shaft or a pin.
It is understood that the first connector 230 may be a plate-like body, a rod-like body, or other structures.
The second housing 220 rotates relative to the first housing 210 such that the rotating shaft assembly 20 has a first state and a second state, and the first housing 210 has a first side 211 and a second side 212 disposed adjacent to each other. In the first state, the second seat 220 is located on the first side 211 of the first seat 210; in the second state, the second housing 220 is located on the second side 212 of the first housing 210.
In an embodiment, the second base 220 can rotate relative to the first base 210 through the first connecting member 230, and the second base 220 is slidably connected with the first connecting member 230, so that the second base 220 is far away from or near the first base 210 when the second base 220 and the first base 210 rotate relatively.
Optionally, one of the first connecting piece 230 and the second base 220 is provided with a first sliding slot 221, and the other one can slide along the first sliding slot 221, so that the second base 220 is far away from or near the first base 210 when the second base 220 and the first base 210 rotate relatively.
For example, the second base 220 is provided with a first sliding slot 221, and the first connecting member 230 is slidably connected to the first sliding slot 221. For another example, the first connecting piece 230 is provided with a first sliding groove 221, and the second seat 220 is slidably connected with the first sliding groove 221.
In an example where the first sliding groove 221 is disposed on the second base 220, the first connecting member 230 can slide along the first sliding groove 221 on the second base 220. Optionally, one end of the first connecting member 230 is rotatably connected to the first base 210, and an end of the first connecting member 230 facing away from the first base 210 may be partially inserted into the first sliding slot 221, so that the first connecting member 230 can slide along the first sliding slot 221. For example, the first connecting piece 230 is provided with a sliding block that can be inserted into the first sliding groove 221, when an external force is applied to the second base 220 to enable the second base 220 to rotate relative to the first base 210 through the first connecting piece 230, the second base 220 drives the first connecting piece 230 to rotate relative to the first base 210, and at the same time, the sliding block on the first connecting piece 230 can slide in the first sliding groove 221 to enable the second base 220 to be far away from or close to the first base 210, so that the rotating shaft assembly 20 can be switched between the first state and the second state.
Of course, the second base 220 and the first connecting member 230 may be slidably connected by other structures. Such as a sliding rail and a sliding groove, and other sliding connection modes.
In one embodiment, the first sliding slot 221 has a start end 221a and a stop end 221b, and the start end 221a and the stop end 221b cooperate to limit the sliding travel of the first connecting member 230 relative to the first sliding slot 221. Wherein the end 221b is close to the first base 210, and the start end 221a is disposed at a side of the end 221b facing away from the first base 210.
Specifically, the start end 221a and the end 221b may be opposite ends of the first chute 221 in a direction in which the first link 230 slides with respect to the first chute 221. In the first state, the first connecting piece 230 is connected to the starting end 221a, i.e. the first connecting piece 230 may be inserted into or pass through the starting end 221a of the first chute 221. In the second state, the first connecting member 230 is connected to the terminating end 221b, i.e. the first connecting member 230 may be inserted into or pass through the terminating end 221b of the first sliding slot 221. In the first state, the first connecting member 230 is connected to the start end 221a, and a side of the first connecting member 230 near the end 221b is a free side, and in the process that the second seat 220 is rotated from the first state to the second state under the action of an external force, the first connecting member 230 can not only rotate relative to the first seat 210 under the action of the force based on the second seat 220, but also slide along the first chute 221 towards the free side.
