Description

ELECTRONIC DEVICE INCLUDING STRUCTURE FOR REDUCING FRICTION

Various embodiments of the present invention relate to an electronic device including a friction reducing structure.

Electronic devices are gradually becoming slimmer, and are being improved to increase rigidity, strengthen design aspects, and differentiate functional elements thereof. BACKGROUND ART Electronic devices are gradually being transformed into various shapes, away from a uniform rectangular shape. The electronic device may have a deformable structure capable of using a large-screen display for portability convenience. For example, as part of a deformable structure, the electronic device may have a structure (eg, a rollable structure) in which a display area is expanded through a housing coupling structure operating in a sliding manner and a flexible display supported thereon. Such an electronic device may require a structure capable of minimizing mutual interference between housings rotatably operating with respect to each other.

The electronic device may include a deformable slideable electronic device (eg, a rollable electronic device) whose display area can be expanded when used. The slideable electronic device includes a housing (eg, a first housing, a base housing, or a base bracket) and a slide structure (eg, a second housing) that can be movably coupled to each other in an at least partially fitted together manner. , a slide housing or a slide bracket). For example, the slide structure may change the display area of the flexible display by sliding-in or sliding-out from the housing in a specified direction and a specified reciprocating distance. The slide structure supports at least a portion of a flexible display (or expandable display) and may be coupled to operate in a sliding manner at least partially from the housing, and may be manually retracted or drawn out by a user, or automatically through an internal drive mechanism. By transitioning to a slide-in state or a slide-out state, the display area may be induced to vary.

The slideable electronic device may have a guide structure coupled to the slide structure from the housing to reciprocate by a predetermined distance. The guide structure may be at least partially accompanied by surface friction (eg, frictional resistance) between the housing and the slide structure, and such surface friction may reduce sliding feeling and/or cause wear and, in severe cases, may cause malfunction. In order to solve this problem, a physical structure (eg, bearing or lubricant) for reducing frictional force may be added to the guide structure. However, when the physical structure is used for a long period of time, the friction reduction effect is reduced, and the above-mentioned problems are again solved. can be induced Also, when the bendable flexible display is moved to the inner space of the housing, a phenomenon in which it is lifted by a restoring force to be unfolded may occur.

Various embodiments of the present disclosure may provide an electronic device including a friction reducing structure.

According to various embodiments, it is possible to provide an electronic device including a friction reduction structure in which operation reliability can be guaranteed even when used for a long period of time.

According to various embodiments, it is possible to provide an electronic device including a structure capable of preventing a floating phenomenon of a flexible display during a retracting/drawing operation.

According to various embodiments of the present disclosure, the electronic device includes a housing including an internal space, a slide structure slidably coupled in a first direction with a specified reciprocating distance from the housing, and at least partially supported by the slide structure. A flexible display accommodated in the inner space so as not to be at least partially visible from the outside in a slide-in state and a first friction reducing structure disposed between the housing and the slide structure, in the housing, the A guide slit disposed parallel to the first direction and having a specified length, a guide protrusion disposed to be guided by the guide slit in the slide structure, at least one first magnet disposed on the gas slit, and the guide protrusion in, at least one second magnet disposed at a position affected by the magnetic force of the first magnet, wherein the at least one first magnet and the at least one second magnet are perpendicular to the first direction The same polarity may be disposed to face each other at least partially along the second direction.

In an electronic device according to exemplary embodiments of the present invention, at least one magnet is disposed in a guide structure between a housing and a slide structure, and friction assists a slide operation by using a magnetic force (eg, repulsive force) of the magnet. By providing the reduced structure, it is possible to induce a reduction in frictional force generated in the guide structure to improve the feeling of sliding and to help maintain operational reliability even when used for a long period of time. In addition, by using the magnetic force of the magnet, it is possible to prevent the floating phenomenon of the flexible display occurring during the retracting/pulling-out operation.

In addition, various effects directly or indirectly identified through this document may be provided.
