Patent Description:
Electronic devices are gradually becoming slimmer, rigidity is increasing, design aspects are being strengthened, and at the same time functional elements are being developed to be differentiated. Electronic devices are moving away from uniform rectangular shapes and gradually being transformed into a variety of shapes. The electronic device may have a deformable structure capable of using a large screen display while being convenient to carry. The electronic device may have a structure (e.g., a rollable structure or a slidable structure) capable of varying a display area of a rollable display (e.g., a flexible display) through support of housings that slide with respect to each other. Such an electronic device may include a drive module (e.g., a driving motor) capable of automatically sliding another housing based on one housing. Patent document <CIT>, discloses an electronic device comprising: a first structure including a first plate having a first surface and a second surface opposite the first surface; a second structure including a second plate facing the second surface of the first plate, a display layer being a flexible display touch screen layer, a conductive pattern mounted on the second plate between the second surface and the second plate; a first conductive path extending between the conductive portion of the first side wall and the conductive pattern; a printed circuit board mounted in the first structure; a wireless charging circuit mounted on the printed circuit board; a wireless communication circuit mounted on the printed circuit board; and flexible conductive paths connected between the printed circuit board and the conductive pattern and including a second conductive path electrically connected between the wireless charging circuit and the conductive pattern and a third conductive path electrically connected between the communication circuit and the first conductive path. Patent document <CIT>, discloses an electronic device (<NUM>), which comprises a housing (<NUM>), a reel (<NUM>), a flexible display screen assembly (<NUM>) and a first battery (<NUM>). The housing (<NUM>) comprises a first portion (<NUM>) and a second portion (<NUM>) that can move relative to each other. Patent document <CIT>, discloses an electronic device including a flexible display which is extendable. Patent document <CIT>, discloses a portable electronic equipment including flexible printed board.

An electronic device may include a rollable electronic device (e.g., a slidable electronic device) in which the display area of the rollable display (e.g., a flexible display) can be expanded and/or reduced. The rollable electronic device may include a first housing and a second housing that are flexibly coupled to each other in an at least partially fitted together manner. For example, the first housing and the second housing may operate to be slidable with respect to each other and support at least a portion of a rollable display (e.g., a flexible display, an expandable display, or a stretchable display) so that in a slide-in state the rollable display may be induced to have a first display area and in a slide-out state it may be induced to have a second display area larger than the first display area.

The electronic device may be disposed between the first housing and the second housing, and it may include a manual slide module (e.g., a spring hinge module) in which the electronic device changes semi-automatically to a slide-in state or a slide-out state in the case of pressing in a direction to close or open above a certain inflection point. However, the manual sliding structure may interfere with the smooth sliding operation because of the repulsive force of the rollable display to unfold, and it may be difficult to design so that the sliding operation is performed by distributing uniformly the repulsive force of the rollable display and the elastic force of the manual slide module (e.g., the spring hinge).

To resolve this difficulty, the electronic device may include a driving module that includes a driving motor including a pinion gear that is disposed in an inner space and enables the second housing to slide automatically based on the first housing gripped by the user, and a rack gear that is gear-coupled with the pinion gear. In the case that the driving motor is driven and the gearing operation is performed while the pinion gear and the rack gear are gear-coupled, the electronic device may automatically perform the sliding operation.

However, the situation is that, in the rollable electronic device, a structure in which the slide stroke is relatively extended in electronic devices having the same size or the efficient disposition design of a driving motor through an efficient electrical connection relationship between the driving motor and the rest of the electronic components has not been considered.

Various embodiments of the present disclosure may provide an electronic device including a driving motor disposed to induce a relatively extended slide stroke.

Accordingly, the rack gear <NUM> disposed on the support bracket <NUM> may be disposed to have a specified length in a slide-out direction (direction ①) from the lower end of the electronic device <NUM> in a slide-in state. In this case, the second housing <NUM> may be moved by a first slide stroke S1 corresponding to the length of the rack gear 2251through the driving of the driving motor <NUM>. In a comparative example, in the case that the driving motor <NUM> is located above the bottom of the electronic device <NUM> in the slide-in state, the second housing 220may move along a rack gear <NUM> having the same length and have a second slide stroke S2 shorter than the first slide stroke S1.
