Abstract
Description
Technical Field
[0001] The present invention relates to an electronic device including a breakage prevention structure.
Background Art
[0002] As the functional gap between manufacturers of electronic devices decreases significantly, electronic devices are gradually being slimmed down to meet the purchasing needs of consumers, developed to enhance the rigidity of the electronic devices, strengthen the design aspect, and differentiate their functional elements. As part of this trend, electronic devices are required to have a robust structure that can withstand impacts transmitted from the outside.
[0003] An electronic device includes a foldable electronic device including a first housing, a second housing foldably coupled to the first housing via a hinge device, and a flexible display disposed to receive support from the first housing and the second housing. The first housing and the second housing are structurally coupled to a hinge module included in the hinge device and operate while receiving support from the hinge module between a folded state and / or a deployed state. For example, the hinge module is at least partially fixed to a hinge housing including a receiving portion and is coupled to a part of the first housing and the second housing via at least one rotator included in the hinge module to induce a folding operation and a deployment operation. In this case, the rotator is disposed to have a flow gap separated by a specified interval in the folding axis direction for a smooth folding operation and a deployment operation.
[0004] However, when a foldable electronic device is exposed to an external impact such as a drop, especially when only one of the two housings is impacted in the folding axis direction, the remaining housing may shift and move in the opposite direction by at least the above-mentioned fluid gap through inertia and / or shearing stress, causing damage and / or malfunction of the flexible display supported by the two housings. Summary of the Invention Problems to be Solved by the Invention

[0008] According to various embodiments of the present invention, an electronic device includes a first housing including a first surface, a second surface facing in a direction opposite to the first surface, and a first side member surrounding a first space between the first surface and the second surface, a second housing foldably connected to the first housing via a hinge device, the second housing including a third surface facing in the same direction as the first surface and a fourth surface facing in a direction opposite to the third surface in a deployed state, and a second side member surrounding a second space between the third surface and the fourth surface, and a flexible display disposed so as to be bandable from at least a part of the first surface across the hinge device to at least a part of the second surface. The hinge device includes a hinge housing including a receiving portion and at least one hinge module including at least one rotor disposed in the receiving portion and connected to the first housing and the second housing. At least a part of the at least one rotor is in contact with the hinge housing at least partially in a folded state and is disposed to be separated from the hinge housing at a specified interval in the deployed state.
Effects of the Invention

In this specification, the surface on which the first display 230 is disposed is defined as the front surface of the electronic device 200, and the opposite surface of the front surface is defined as the rear surface of the electronic device 200. Also, the surface surrounding the space between the front surface and the rear surface is defined as the side surface of the electronic device 200.
[0014] According to various embodiments, a pair of housings 210, 220 includes a first housing 210 and a second housing 220 that are foldably arranged relative to each other via a hinge device (e.g., the hinge device 300 of FIG. 3). According to one embodiment, the pair of housings 210, 220 is not limited to the shapes and couplings shown in FIGS. 1 and 2, and is implemented by other shapes or combinations and / or couplings of components. According to one embodiment, the first housing 210 and the second housing 220 are arranged on both sides with respect to a folding axis A1 and have a shape that is overall symmetric with respect to the folding axis A1. According to certain embodiments, the first housing 210 and the second housing 220 are folded asymmetrically with respect to the folding axis A1. According to one embodiment, the first housing 210 and the second housing 220 have different angles and distances with respect to each other depending on whether the electronic device 200 is in an unfolded state, a folded state, or an intermediate state.
[0015] According to various embodiments, the first housing 210 is coupled to a hinge device (e.g., the hinge device 300 of FIG. 3) in the deployed state of the electronic device 200, and includes a first surface 211 disposed to face the front of the electronic device 200, a second surface 212 facing in a direction opposite to the first surface 211, and / or a first side member 213 surrounding at least a portion of the first space between the first surface 211 and the second surface 212. According to one embodiment, the second housing 220 is coupled to a hinge device (e.g., the hinge device 300 of FIG. 3) in the deployed state of the electronic device 200, and includes a third surface 221 disposed to face the front of the electronic device 200, a fourth surface 222 facing in a direction opposite to the third surface 221, and / or a second side member 223 surrounding at least a portion of the second space between the third surface 221 and the fourth surface 222. According to one embodiment, the first surface 211 faces in a direction substantially the same as the third surface 221 in the deployed state and at least partially faces the third surface 221 in the folded state. According to one embodiment, the electronic device 200 includes a recess 201 formed to receive the first display 230 through a structural coupling between the first housing 210 and the second housing 220. According to one embodiment, the recess 201 has substantially the same size as the first display 230.
[0016] According to various embodiments, the hinge housing 310 (e.g., hinge cover) is disposed between the first housing 210 and the second housing 220 and is arranged to cover a hinge module (e.g., hinge module 320 in FIG. 3) disposed in the hinge housing. According to one embodiment, the hinge housing 310 is covered by a part of the first housing 210 and the second housing 220 or is exposed to the outside according to the deployed state, folded state, or intermediate state of the electronic device 200. For example, when the electronic device 200 is in the deployed state, at least a part of the hinge housing 310 is covered by the first housing 210 and the second housing 220 and is substantially not exposed. According to one embodiment, when the electronic device 200 is in the folded state, at least a part of the hinge housing 310 is exposed to the outside between the first housing 210 and the second housing 220.

In this case, the first region 230a and the second region 230b of the first display 230 form a narrow angle (e.g., in the range of 0 degrees to about 10 degrees) with each other via the folding region 230c and are arranged to face each other. According to one embodiment, at least a part of the folding region 230c is deformed into a curved shape having a predetermined curvature. According to one embodiment, when the electronic device 200 is in an intermediate state, the first housing 210 and the second housing 220 are arranged at a certain angle with respect to each other.

However, such a flow gap acts as a cause of shear stress when the electronic device 200 drops or when one housing receives an impact, causing the other housing to move in the opposite direction, and causing damage (e.g., disconnection of wiring) to the display 230 by shifting or deforming both housings along the folding axis by the amount of the flow gap. The electronic device 200 according to an exemplary embodiment of the present invention includes a damage prevention structure for removing such a flow gap when in the folded state.

[0044] FIG. 5 is a schematic view of an electronic device showing an arrangement state of a hinge device according to various embodiments of the present invention.
[0045] In the description of the electronic device 200 of FIG. 5, the same reference numerals are assigned to substantially the same components as those of the electronic device 200 of FIGS. 4a and 4b, and detailed descriptions thereof are omitted.
[0046] FIG. 5 shows the arrangement relationship among the hinge device 300, the first housing 210, and the second housing 220 when the electronic device is in the deployed state. According to one embodiment, the electronic device 200 includes a first housing 210, a second housing 220, and a hinge device 300 that connects the first housing 210 and the second housing 220 to be foldable relative to each other.

[0047] FIG. 6a is an enlarged view of region 6a of FIG. 5 according to various embodiments of the present invention. FIG. 6b is a partial cross-sectional perspective view of the hinge housing and the rotator viewed along line 6b-6b of FIG. 6a according to various embodiments of the present invention.
[0048] Referring to FIGS. 6A and 6B, when the first housing 210 and the second housing 220 perform a folding operation and / or a deployment operation with respect to each other, the first rotor 331 and the second rotor 332 are arranged in the receiving portion 3101 of the hinge housing 310 to have fluid gaps g1, g2 separated from the first closed end 312 at a specified interval in a direction parallel to the folding axis A1. According to one embodiment, the fluid gaps g1, g2 are provided to minimize interference caused by contact between the first rotor 331 and the second rotor 332 with the hinge housing 310 during the operation of folding and deploying the first housing 210 and the second housing 220, or in the deployed state. Such fluid gaps g1, g2 are maintained from the deployed state until immediately before the folding state of the first rotor 331 and the second rotor 332 (for example, from the fully folded state to a folding angle about 5° before). Although not shown, the third rotor 333 and the fourth rotor 334 also have substantially the same structure with respect to the second closed end 313.
[0049] According to an exemplary embodiment of the present invention, the first rotor 331 includes a protrusion 3311 formed to extend in the direction of the first closed end 312. According to one embodiment, the protrusion 3311 includes an attachment surface 331a facing a display (e.g., the display 230 in FIG. 4a) and a side surface 331b extending from the attachment surface 331a and facing the first closed end 312. According to one embodiment, the first rotor 331 includes a first inclined portion 3312 formed to be inclined at a specified angle θ on the side surface 331b of the protrusion 3311. According to one embodiment, the first closed end 312 includes a second inclined surface 3122 formed at a corresponding position so as to contact the first inclined surface 3312 when the electronic device 200 is in the folded state. According to one embodiment, the second inclined surface 3122 is formed at a position where it does not contact the first inclined surface 3312 even when the first rotor 331 moves from the deployed state to immediately before the folded state. In an embodiment, the first inclined surface 3312 included in the protrusion 3311 is formed in a structure that does not contact the second inclined surface 3312 even when the first rotor 331 moves from the deployed state to immediately before the folded state. According to one embodiment, the second inclined surface 3312 is formed at a position where it is in surface contact with the first inclined surface 3312 when the electronic device 200 reaches the folded state. Therefore, the first inclined portion 3312 is formed to gradually become lower as it advances in the -z axis direction in the deployed state. According to one embodiment, the second inclined portion 3122 is formed to gradually become higher as it advances in the x axis direction.
[0050] Although not shown, the second rotor 332 and the first closed end 312, the third rotor 333 and the second closed end 313, and / or the fourth rotor 334 and the second closed end 313 are also configured to have substantially the same contact structure as the contact structure between the first inclined portion 3312 and the second inclined portion 3122 formed between the first rotor 331 and the first closed end 312.
[0051] FIG. 7a is a partial configuration diagram showing the arrangement structure of the hinge housing and the rotors in the folded state according to various embodiments of the present invention. FIG. 7b is a cross-sectional view showing a schematic coupling structure of the hinge housing and the rotors as viewed along line 7b-7b of FIG. 7a according to various embodiments of the present invention.
[0052] FIG. 7a is a partial cross-sectional view of the electronic device viewed along line 7a-7a of FIG. 4b.
[0053] Referring to FIGS. 7a and 7b, in the folded state of the electronic device 200, the first inclined portion 3312 of the first rotor 331 contacts the second inclined portion 3122 of the first closed end 312. According to one embodiment, the first inclined portion 3312 and the second inclined portion 3122 contact in a manner of at least partially surface contact. Although not shown, the second rotor 332 and the first closed end 312, the third rotor 333 and the second closed end 313, and / or the fourth rotor 334 and the second closed end 313 also contact at least partially in surface contact in substantially the same manner as the first inclined portion 3312 and the second inclined portion 3122 respectively formed between the first rotor 331 and the first closed end 312. In this case, in the folded state, at least a part of the flow gaps g1, g2 provided in a direction parallel to the folding axis A1 between the rotors 331, 332, 333, 334 and the hinge housing 310 is filled through the contact structure between the first inclined portion 3312 and the second inclined portion 3122, so that even when an external impact such as a drop is applied, the phenomenon that both housings 210, 220 are displaced or distorted by a shearing force is reduced. Further, the first inclined portion 3312 and the second inclined portion 3122 do not contact each other from the unfolded state until immediately before the folded state (for example, from the completely folded state to about 5° before the folding angle), and flow gaps g1, g2 are provided between the rotors 331, 332, 333, 334 and the hinge housing 310, which is helpful for the smooth folding and unfolding operations of the electronic device 210.
[0054] FIG. 7c is a cross-sectional view showing a schematic coupling structure of the hinge housing and the rotor according to various embodiments of the present invention.
[0055] Referring to FIG. 7c, when the electronic device 200 transitions to the folded state, noise is generated or unwanted frictional force is generated by the pressing force of at least one hinge module 320 on the first inclined portion 3312 of the first rotator 331 and the second inclined portion 3122 of the first closed end 312. According to an exemplary embodiment of the present invention, the electronic device 200 includes a buffer layer 3123 disposed between the first inclined portion 3312 and the second inclined portion 3122. According to one embodiment, the buffer layer 3123 is formed on the first inclined portion 3312 and / or the second inclined portion 3122. According to one embodiment, the buffer layer 3123 includes an elastic coating layer or a Teflon (registered trademark) coating layer based on an elastic material (e.g., urethane, rubber, resin, or silicon) disposed on the first inclined portion 3312 and / or the second inclined portion 3122. Although not shown, the same buffer layer 3123 can be substantially applied to the second rotator 332 and the first closed end 312, the third rotator 333 and the second closed end 313, and / or the fourth rotator 334 and the second closed end 313.
[0056] FIG. 8 is an operation diagram showing the operation locus of the rotator with respect to the hinge housing while transitioning from the unfolded state to the folded state according to various embodiments of the present invention.
[0057] Referring to FIG. 8, while the electronic device 200 transitions from the folded state to the unfolded state, the first rotor 331 moves from the position (a) in the unfolded state with respect to the hinge housing along the trajectories of (b), (c), and (d) and finally to the position (e) in the folded state. In this case, the first rotor 331 does not contact the hinge housing 310 in a direction substantially parallel to the folding axis A1 (for example, the y-axis direction) during the states of (a) to (d). For example, the first rotor 331 has the protruding portion 3311 and the first inclined portion 3312 that do not contact the first closed end 312 of the hinge housing 310 during the states of (a) to (d). According to an embodiment, the first inclined portion 3312 of the first rotor 331 contacts the second inclined portion 3122 of the hinge housing 310 when the electronic device 200 reaches the folded state (for example, the state of (e)). Therefore, when the electronic device 200 is folded for portable use (when the possibility of dropping is relatively high), the fluid gaps (for example, the fluid gaps g1, g2 in FIG. 6a) formed between the hinge housing 310 and the first rotor 331 in the direction of the folding axis A1 are filled through the surface contact of the first inclined portion 3312 and the second inclined portion 3122, thereby reducing the distortion and displacement phenomena of the two housings 210 and 220 caused by dropping. Although not shown, the second rotor 332 and the first closed end 312, the third rotor 333 and the second closed end 313, and / or the fourth rotor 334 and the second closed end 313 also have substantially the same contact structure when in the folded state.
[0058] FIGS. 9A and 9B are diagrams schematically showing the arrangement structures of the hinge housing and the rotors in the unfolded state and the folded state of an electronic device according to various embodiments of the present invention.
[0059] Referring to FIGS. 9A and 9B, the electronic device 200 includes a first housing 210, a second housing 220, and a hinge device 300 that foldably connects the first housing 210 and the second housing 220 to each other. According to one embodiment, the hinge device 300 includes a hinge housing 310 having a length in a direction substantially parallel to the folding axis A1, and a hinge module 320 fixed to the hinge housing 310 and including rotators 331, 332, 333, 334 coupled to the first housing 210 and the second housing 220. According to one embodiment, the rotators 331, 332, 333, 334 are disposed near a first closed end 312 formed in an upper region UA of the hinge housing 310, and include a first rotator 331 and a second rotator 332 respectively coupled to the first housing 210 and the second housing 220, and are disposed near a second closed end 313 formed in a lower region LA, and include a third rotator 333 and a fourth rotator 334 respectively coupled to the first housing 210 and the second housing 220. According to one embodiment, the first rotator 331 and the third rotator 333 are coupled to a first support member 261 included in the first housing 210, and the second rotator 332 and the fourth rotator 334 are coupled to a second support member 262 included in the second housing 220.
[0060] According to various embodiments, the first rotator 331 does not contact the second inclined portion 3122 formed at the first closed end 312 of the hinge housing 310 by the first inclined portion 3312 in the upper region UA until the electronic device 200 reaches immediately before the folded state from the unfolded state. Similarly, in the upper region UA, the second rotator 332 also does not contact the first closed end 312 of the hinge housing 310. Similarly, in the lower region LA, the third rotator 333 also does not contact the second closed end 313 of the hinge housing 310. Similarly, in the lower region UA, the fourth rotator 334 also does not contact the second closed end 313 of the hinge housing 310.
[0061] According to various embodiments, when the electronic device 200 reaches the folded state, the first rotor 331 contacts, in the first upper region UA1, the second inclined portion 3122 formed at the first closed end 312 of the hinge housing 310 with the first inclined portion 3312. Similarly, the second rotor 332 contacts at least a part of the first closed end 312 in substantially the same manner in the second upper region UA2. Similarly, the third rotor 333 contacts at least a part of the second closed end 313 in substantially the same manner in the first lower region LA1. Similarly, the fourth rotor 332 contacts at least a part of the second closed end 313 in substantially the same manner in the second lower region LA2. Therefore, when the electronic device 200 transitions to the folded state, by filling the fluid gaps (e.g., the fluid gaps g1, g2 in FIG. 6a) formed between the hinge housing 310 and the rotors 331, 332, 333, 334 in the folding axis A1 direction through surface contact of the inclined portions (e.g., the first inclined portion 3312 and the second inclined portion 3122), it is possible to reduce the distortion or displacement phenomenon of the two housings 210, 220 due to external impacts such as dropping.
[0062] FIG. 10 is an enlarged view of region 10 of FIG. 5 according to various embodiments of the present invention.
[0063] The electronic device 200 according to an exemplary embodiment of the present invention in the unfolded state includes an additional damage prevention structure for reducing the displacement or distortion of the two housings 210, 220 caused by external impacts such as dropping.
[0064] Referring to FIG. 10, the first rotor 331 protrudes in the direction of the second rotor 332 (e.g., the -x axis direction) in the deployed state of the electronic device 200, and includes a first coupling protrusion 3315 formed to be fitted together with a first receiving groove 3325 formed in the second rotor 332. According to an embodiment, the second rotor 332 protrudes in the direction of the first rotor 331 (e.g., the x axis direction) in the deployed state of the electronic device 200, and includes a second coupling protrusion 3326 formed to be fitted into a second receiving groove 3316 formed in the first rotor 331. According to an embodiment, the first and second coupling protrusions 3315 and 3326 and the first and second receiving grooves 3325 and 3316 are coupled only when the electronic device 200 is in the deployed state, and are disengaged so as not to interfere with each other while moving from the deployed state to the folded state. Therefore, when the electronic device 200 is in the deployed state, the first coupling protrusion 3315 is coupled to the first receiving groove 3325, and the second coupling protrusion 3326 is coupled to the second receiving groove 3316, thereby reducing the phenomenon of distortion or displacement in a direction parallel to the folding axis A1 of the two housings 210 and 220 due to an external impact such as a drop.
[0065] FIG. 11 is a partial perspective view of an electronic device including a hinge housing and a break prevention structure disposed between two housings in region 11 of FIG. 4b according to various embodiments of the present invention.
[0066] Referring to FIG. 11, in the folded state, the electronic device 200 includes an additional blocking structure for filling the fluid gap g3 formed between the hinge housing 310 and the first housing 210 and the second housing 220. According to one embodiment, the electronic device 200 includes a first contact protrusion 315 disposed to fill the fluid gap g3 between the first housing 210 and the hinge housing 310 in the folded state. According to one embodiment, the first contact protrusion 315 is formed at a corresponding position of the first housing 210 or at a corresponding position on the outer surface of the hinge housing 310. In certain embodiments, the first contact protrusion 315 can also replace the surface contact structure of the first inclined portion (e.g., the first inclined portion 3312 in FIG. 6a) and the second inclined portion (e.g., the second inclined portion 3122 in FIG. 6a) described above. According to one embodiment, the electronic device 200 includes a second contact protrusion 316 having substantially the same structure as the first contact protrusion 315 to fill the fluid gap g3 between the second housing 220 and the hinge housing 310. According to one embodiment, the first housing 210 and the second housing 220 are separated from the hinge housing 310 through the fluid gap g3 until immediately before the folded state, and in the folded state, the fluid gap is filled through the first contact protrusion 315 and the second contact protrusion 316, so that the hinge housing 310 contacts in a direction substantially parallel to the folding axis A1. Although not shown, in the lower region, the electronic device 200 also has substantially the same protrusions disposed between the hinge housing 310 and the first housing 210 and between the hinge housing 310 and the second housing 220. Therefore, the electronic device 200 according to an exemplary embodiment of the present invention can reduce the displacement or distortion phenomenon of the two housings 210 and 220 generated by an external impact such as a fall in the unfolded state.
[0067] According to various embodiments, an electronic device (e.g., the electronic device 200 in FIG. 5) includes a first housing (e.g., the first housing 210 in FIG. 5), a second housing (e.g., the second housing 220 in FIG. 5), and a hinge device (e.g., the hinge device 300 in FIG. 5) that movably connects the first housing and the second housing relative to each other with respect to a folding axis (e.g., the folding axis A1 in FIG. 5). The hinge device includes a hinge housing (e.g., the hinge housing 310 in FIG. 5) including a receiving portion (e.g., the receiving portion 3101 in FIG. 5), and a hinge module (e.g., the hinge module 320 in FIG. 5) disposed in the receiving portion and including at least one rotator (e.g., the first rotator 331 in FIG. 5) that connects the first housing and the second housing. The hinge device further includes a flexible display (e.g., the flexible display 230 in FIG. 4a) disposed to support at least a part of the first housing, the second housing, and the hinge device. At least one rotator is arranged such that at least a part thereof is in a folded state and at least partially contacts the hinge housing, and in a deployed state, is spaced apart from the hinge housing by a specified interval.

In the folded state, at least one rotator contacts such that the first inclined portion is at least partially in surface contact with a second inclined portion formed on the first closed end and / or the second closed end.
[0071] According to various embodiments, the first inclined portion is formed to gradually increase in a direction perpendicular to the folding axis direction in the deployed state, and the second inclined portion is formed in a shape corresponding to contact the first inclined portion in the folded state.
