Description

BACKGROUND

1. Field

The disclosure relates to an electronic device including a drive motor.

2. Description of Related Art

Electronic devices are gradually becoming slimmer and more rigid, being strengthened in design aspects, and being improved to differentiate functional elements thereof. Electronic devices are being gradually transformed from a uniform rectangular shape into various shapes. An electronic device may have a transformable structure that is convenient to carry and enables the use of a large-screen display. The electronic device may have a structure capable of making the display area of a rollable display (e.g., a flexible display) variable by supporting housings that operate in a sliding manner relative to each other (e.g., a rollable structure or a slidable structure). This electronic device may include a drive module (e.g., a drive motor) configured to allow, with respect to one housing, a remaining housing to automatically slide.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

An electronic device may include a rollable electronic device in which the display area of a rollable display is expandable and/or contractible (e.g., a slidable electronic device). The rollable electronic device may include a first housing and a second housing that are coupled to each other to be movable relative to each other by being at least partially fitted together. For example, the first housing and the second housing operate slidably 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), whereby, in a slide-in state, the rollable display may be guided to have a first display area, and in a slide-out state, the rollable display may be guided to have a second display area that is greater than the first display area.

The electronic device may include a manual slide module (e.g., a spring hinge module) that is disposed between the first housing and the second housing and is semi-automatically changed to the slide-in state or the slide-out state when pressed in a direction of being closed or opened beyond a predetermined inflection point. However, the manual sliding structure may interfere with a smooth sliding operation by the repulsive force of the rollable display and may be difficult to design to perform the sliding operation by uniformly distributing the repulsive force of the rollable display and the elastic force of the manual slide module (e.g., a spring hinge).

In order to solve these difficulties, the electronic device may include a drive motor including a pinion gear that operates the second housing to be automatically slidable with respect to the first housing held by a user, and a rack gear engaged with the pinion gear. When the drive motor is driven and the gearing operation is performed while the pinion gear and the rack gear are engaged with each other, the electronic device may automatically perform the sliding operation.

However, in the rollable electronic device, an efficient electrical connection structure between the drive motor and a board (e.g., a main board) disposed in the inner space, a structure to support the display during sliding operation, or the layout design of peripheral electronic components to improve the driving force of the drive motor is not being considered.

According to various embodiments, the electronic device 200 may include a battery B disposed via a support bracket 225 fixed to the first space 2101 of the first housing 210. According to this, the battery B is not disposed in the second housing 220, which operates as a movable structure (e.g., a slide structure), but is disposed in the first housing 210, which is a fixed structure. Thus, a separate driving gap may not be required to avoid interference with peripheral structures due to movement. Accordingly, the thickness of the battery B is increased such that the battery is close to or in contact with the rear surface of the support member 240 from the battery seating portion 2251 of the support bracket 225, so that the volume of the battery may be increased. In addition, in the slide-in state, the battery B may be disposed to support the rear surface of the support member 240, so that sagging of the rollable display 230 may be reduced and operational reliability may be improved.

According to an embodiment, the electronic device 200 may include a drive motor 260 disposed on a support bracket 225 fixed to the first space 2101 of the first housing 210 and a rack gear (e.g., the rack gear 2221 in FIG. 4) disposed in the second space 2201 of the second housing 220 to be engaged with the pinion gear 261 of the drive motor 260. According to an embodiment, when the drive motor 260 operates, the rack gear 2221 may move along the first direction (e.g., the y-axis direction) or the second direction (e.g., the −y-axis direction), and the first housing 210 may also move therewith. For example, in the case where the slide-out state is switched to the slide-in state, the support member 240 supporting the rollable display 230 may be bent to have a predetermined radius of curvature R2 while being supported by the support portion 2252 provided at the edge of the support bracket 225 and then be accommodated in the first space 2101 of the first housing 210 in the manner of being bent.

According to various embodiments, the drive motor 260 fixed to the support bracket 225 may have a predetermined radius R1. In this case, by configuring the radius of curvature R2 in a bending area (area D) of the support member 240 to be larger than the radius R1 of the drive motor 260, interference applied to the rollable display 230 by the drive can be avoid during operation.
