In addition, the present invention provides a tablet computer capable of sliding and tilting which can buffer the impact force generated during opening and closing operations.

In addition, the present invention provides a tablet computer capable of improving stability and reliability, and capable of prolonging its service life.

According to another aspect of the present invention, there is provided a tablet computer including a first body, a second body overlapping the first body, a first body rotatably connected to the first body, A first link member rotatably connected to the second body at the other end, a second link member connected to the first body so as to be slidably and rotatably connected to the first body and the other end rotatably connected to the second body, A connecting link member rotatably connected to the link member and rotatably connected to the second link member at the other end, and a connecting link member rotatably connected to the second link member to decelerate the moving speed of the second main body in at least a part of the opening / closing interval of the second main body with respect to the first main body Wherein a distance between the second link member and the first link member is limited within a predetermined distance by the connecting link member upon rotation of the first link member, Performing a sliding movement and a tilting movement is continuously on, and is opened and closed.

For reference, in the present invention, the first body and the second body can be understood as a housing (or case) of a main body constituting a conventional tablet computer. Alternatively, the first main body and the second main body may be manufactured separately from the main body, Elements (e. G., Various plates, frames, etc.).

In addition, an interface may be provided on the exposed surface of the first body exposed when the second body is opened. The interface unit may include at least one of a conventional input device and an output device. For example, the input device may include at least one of a keypad, a button, a switch, a dial, a pointing device, and a touch pad, and the output device may include at least one of a display, a light emitting device, and a speaker. In addition, other conventional additional devices may be used as the interface portion, and the present invention is not limited or limited by the type and characteristics of the interface portion.

The position, number and spacing of each link member can be appropriately changed according to required conditions and design specifications, and when the second main body is closed, each link member is disposed substantially parallel between the first main body and the second main body . Of course, in some cases, it is also possible that each link member is arranged to be inclined between the first body and the second body when the second body is closed.

In addition, in the present invention, each link member is rotatably connected to the corresponding other link member or body. The link member is connected to the other link member and the corresponding link member via a common shaft means such as a rotation pin, It can be understood as being rotatably coupled to the body.

A guide plate can be coupled to the back surface of the second body, and the other end of the first link member and the other end of the second link member can be modularized together with the guide plate by being rotatably coupled to the guide plate. The other end of the first and second link members may be directly coupled to the second body. Alternatively, only one of the first and second link members may be coupled to the second body through a separate member such as a guide plate, As shown in FIG.

In addition, one end of the second link member is slidably and rotatably connected to the first main body. To this end, a guide rail is formed in the first main body so that one end of the second link member is slidably and rotatably received . For example, a guide bracket may be coupled to the first body, and a guide rail may be formed on the guide bracket. In some cases, the guide rail may be formed directly on the first main body.

The section in which the damping force by the damping section acts can be appropriately changed according to the required conditions and design specifications. For example, the damping force by the damping portion may act only in some sections of the opening / closing section of the second main body (for example, a section adjacent to at least one of the positions where the opening and closing of the second main body is completed) , And in some cases, the damping force by the damping portion may act over the entire opening / closing section of the second main body.

As the damping portion, various conventional damping devices may be used depending on the required conditions and design specifications, and the present invention is not limited or limited by the structure and characteristics of the damping portion. For example, the damping portion may be configured to provide a damping force using at least one of frictional resistance, fluid resistance, and spring resistance.

The damping unit may be connected to at least one of the first link member and the second link member and mechanically linked by rotation of the first link member and the second link member, Damping force can be provided.

In some cases, the damping housing may be mounted on the first link frame (or the second link frame), and the damping protrusion may be formed on the first body.

The shape and size of the damping protrusion can be appropriately changed in accordance with required conditions and design specifications. For example, an axial coupling portion for axial coupling with the first body may be formed at one end of the first link member, and the damping projection may be formed by partially removing the axial coupling portion. For example, the damping protrusion may be formed in a substantially "C" shape having an opening on a side surface. The length and the shape of the opening may be variously changed according to required conditions and design specifications, and in some cases, the damping protrusion may be formed to have a plurality of openings. Further, the end of the damping rod may be provided with a damping guide, and the damping rod may be in contact with the damping projection via the damping guide.

The sliding and tiltingable tablet computer according to the present invention can simplify the structure and provide convenience in use.

In particular, according to the present invention, the distance between the second link member and the first link member can be limited within a predetermined distance by the connecting link member upon rotation of the first link member, The moving and tilting movement can be continuously performed, and the opening and closing operation can be performed more simply.

According to the present invention, when the second main body is opened and closed with respect to the first main body, by pulling and pushing one end of the second link member by the connecting link member, when the second main body is opened and closed, (The distance between the lower end of the second main body and the upper surface of the first main body) of the second main body with respect to the first main body when the second main body is opened and closed, Can be minimized, and operation stability and reliability can be improved.

In addition, according to the present invention, since lifting of the second body relative to the first body can be minimized when the second body is opened and closed, the force necessary for the opening and closing operations can be effectively transmitted. For example, since the direction in which the force is applied during the opening operation can be substantially linear, it can be opened by a simple operation without the hassle of changing the direction of the force in the middle or changing the strength of the force.

In addition, according to the present invention, since lifting of the second body relative to the first body can be minimized, a superior aesthetic appearance can be created during opening and closing operations, and convenience in use can be provided. That is, when the distance between the first main body and the second main body is larger in the opening and closing operation, the aesthetics are not good and the opening and closing operation is troublesome and inconvenient. However, according to the present invention, since the tilting operation can be realized in a state in which the distance between the first body and the second body is minimized, it is possible to create a convenient appearance with a convenient opening and closing.

Further, according to the present invention, since the second main body can slide and move with respect to the first main body simultaneously with the tilting movement, in other words, the second main body can be opened and closed with a minute spacing with respect to the first main body, Interference between the second main body and the first main body can be prevented in advance, and there is no need to employ a separate structure for preventing mutual interference between the main bodies.

According to the present invention, the moving speed of the second body can be reduced by the damping force of the damping part when the second body is opened and closed, and the impact force can be buffered instantaneously when the second body is opened or closed. Therefore, the opening and closing operation of the second body can be implemented smoothly without impact, and the damage and breakage of the product due to the impact force can be prevented, and the service life can be extended.

In addition, according to the present invention, since the section in which one end of the second link member slides can be formed only in a specific section without being formed over the entire section of the first body, (For example, a keypad area) of the main body 1 can be secured more widely, and space utilization and design freedom of the tablet computer can be improved.

In addition, according to the present invention, since the interface unit exposed on the upper surface of the first main body can be used when the second main unit is opened, various input and output functions can be performed and the angle of the display unit can be uniform .

Further, according to the present invention, the second main body can be automatically tilted open by a simple opening operation of the user. That is, the restraint by the restraining portion is released by the linear operation of the operating member without the need to perform the separate slide operation and the tilting operation to tilting the second main body simultaneously, and at the same time, the second main body is automatically tilted open It is possible to provide convenience in use.

The damping spring 550 provides an elastic force such that the damping rod 530 can elastically contact the damping protrusion 510. For example, a conventional coil spring may be used as the damping spring 550 and interposed between the damping housing 520 and the damping rod 530 to elastically support the damping rod 530.

Hereinafter, an operating structure of a sliding and tilting tablet computer according to the present invention will be described.

In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

4, in the initial state (closed state), the first body 10 and the second body 20 are disposed so as to overlap with each other. At this time, the first link member 200, the second link member 300, and the connection link member 400 are disposed in a folded state such that they overlap each other between the first body 10 and the second body 20 . In this way, in the initial state, the user can input or output various information by using the display unit 22 provided in the second main body 20.

Thereafter, in order to use the tablet computer with the second main body 20 opened with respect to the first main body 10, as shown in FIGS. 5 through 7, the user pushes up the second main body 20, 2 body 20 can be opened with respect to the first main body 10. That is, when the lower end of the second main body 20 is pushed up, as in the case of sliding the slide portion in a conventional slide type personal portable terminal, the first link member 200 and the second link As the member 300 rotates, the second main body 20 can be slid with respect to the first main body 10, rotated at a predetermined angle, and tilted open. In this way, when the second main body 20 is opened, various information can be input or output using the interface unit 12 exposed on the top surface of the first main body 10. [

In addition, the opening of the second main body 20 with respect to the first main body 10 can be realized in a semi-automatic manner by the driving force of the actuator 700, The damping force is applied to the first link 100 member, so that the moving speed of the second main body 20 can be reduced. 6, the damping protrusions 510 can be brought into contact with the damping rod 530 as the rotation of the first link member 200 proceeds a certain distance or more, and the damping rod 530 is fitted to the damping protrusions 510, The rotational speed of the first link member 200 can be reduced by the damping force as the first link member 200 is elastically contacted. Accordingly, the opening movement speed of the second main body 20 can be reduced by the damping force.

Even when the second body 20 is closed, one end of the second link member 300 is pushed by the connecting link member 400 and the other end of the first link member 200 The lifting effect of the second body 20 with respect to the first body 10 can be minimized when the first body 10 is closed and the closing speed of the second body 20 with the damping portion It can be decelerated.

8 to 10 illustrate a tablet computer capable of sliding and tilting according to another embodiment of the present invention. In addition, the same or equivalent portions as those in the above-described configuration are denoted by the same or equivalent reference numerals, and a detailed description thereof will be omitted.

8 to 10, according to another embodiment of the present invention, the tablet computer includes a restraining part temporarily restraining a closed state of the second main body 20 with respect to the first main body 10, The first actuator 1100 may be provided with an elastic force such that the second body 20 is automatically opened when the first actuator 1100 is released from the restraint by the restricting portion. So that the second main body 20 is automatically opened.

More specifically, the first actuator 1100 may provide an elastic force to rotate the first link member 200 in the direction in which the first link member 200 stands with respect to the first body 10, and the type and characteristics of the first actuator 1100 Can be variously changed according to the required conditions and design specifications. For example, a conventional torsion spring may be used as the first actuator 1100, and the first actuator 1100 may be configured to provide an elastic force such that the first link member 200 always rotates with respect to the first body 10 .

The restricting portion is provided for temporarily restricting the closed state of the second body 20 with respect to the first body 10. The closed state of the second body 20 with respect to the first body 10 is restricted by the rotation of the first link member 200 (and the second link member) with respect to the first body 10, Can be understood as being constrained.

The restricting portion may be provided in various structures for temporarily restricting the closed state of the second main body 20 with respect to the first main body 10. [ For example, the restricting portion includes an operating member 910, a restricting projection 920, and a locking member 932. [

The operating member 910 may be provided in various ways that can be operated linearly on the first main body 10 in accordance with required conditions and design specifications. For example, the operating member 910 may be provided on the side surface of the first main body 10 in a pushing manner in a pushing manner. In some cases, the operating member may be provided linearly on the front or rear surface of the first body, or alternatively, the operating member may be provided on the second body.

The restraining protrusion 920 may be provided on at least one of the first link member 200 and the second link member. The restricting protrusion 920 may be formed on the bottom surface of the first link member 200 and may be configured to restrain the rotation of the first link member 200 relative to the first main body 10 by restricting the restricting protrusion 920. [ Can be restrained.

The locking member 932 has a restraining groove 932 for restraining the restraining protrusion 920 so that the locking member 932 is interlocked by the operating member 910 and selectively releases the restraining position for restraining the restraining protrusion 920, And may be configured to move elastically linearly to the unlocked position. The locking member 932 may be connected to the operating member 910 and linearly move in the same direction as the operating member 910 and may be elastically supported by a conventional elastic member 934 such as a spring have. The rotation of the first link member 200 relative to the first main body 10 is restricted by the restricting protrusion 920 being received and restrained in the restricting groove 932 in a state where the locking member 932 is disposed at the restraining position Rotation of the first link member 200 relative to the first main body 10 can be allowed by pulling the restricting protrusion 920 out of the restricting groove 932 when the locking member 932 is disposed in the release position .

In the above-described embodiment of the present invention, the operation member 910 is provided in such a manner that it can be pushed and operated in the same direction as the moving direction of the locking member 932. However, in some cases, (For example, the longitudinal direction of the first main body) crossing the moving direction of the locking member, and the locking member is interlocked and linearly moved by the sliding operation of the operating member It is also possible to do. In some cases, it is also possible to form a restricting groove in the first link member (or the second link member) and to form a restricting projection in the locking member.

In addition, the second body 20 may include a second actuator 1200 that provides an elastic force to elastically open the second body 20. Of course, it is possible to automatically open the second main body when the restraint of the restricting portion is released only by the elastic force of the first actuator (or only the second actuator). However, when the first actuator alone is used, There is a problem in that the thickness and diameter of the actuator (spring or cam member) inevitably become large in order to secure the lifetime and the reliability. However, in the present invention, by using the first actuator 1100 and the second actuator 1200 together, a sufficient elastic force can be provided without increasing the thickness and size, and the elastic opening of the second body 20 can be stably realized have.

The structure and characteristics of the second actuator 1200 may be variously changed according to required conditions and design specifications. For example, when the rotation of the first link member 200 with respect to the first main body 10 is progressed to a certain degree or more, the second actuator 1200 moves the first link member 200 relative to the first main body 10 It is possible to provide an elastic force. Hereinafter, an example in which the second actuator 1200 includes the driving cam member 1210 and the driven cam member 1120 will be described. In some cases, the second actuator may be connected to the second link member or independently connected to the first and second link members.

The driving cam member 1210 is connected to the first link member 200 and can rotate integrally with the first link member 200. For example, a drive cam profile (not shown) may be formed at both ends of the drive cam member 1210, and the shape and structure of the drive cam profile may be variously changed according to required conditions and design specifications . For example, the drive cam profile may be provided in a form in which a valley portion and a peak portion having a height difference along the axial direction are alternately arranged. In some cases, only one drive cam member may be used and only one follower cam member to be described later may be used.

The follower cam member 1120 has a driven cam profile (not shown) having a turning point and is provided at both ends of the drive cam member 1210 so as to elastically contact and interact with the drive cam member 1210 . For example, a housing 1230 can be coupled to both ends of the driving cam member 1210, and the driven cam member 1120 is linearly moved along the inside of the housing 1230 and contacts the driving cam member 1210 Can interact.

A spring member 1240 may be provided inside the housing 1230 to provide an elastic force to move the driven cam member 1120 in a direction in which the driven cam member 1120 approaches the drive cam member 1210. The structure and type of the spring member 1240 can be variously changed according to required conditions and design specifications.

The linear motion of the driven cam member 1220 can be converted into the elastic rotational motion by the interaction between the driven cam member 1220 and the drive cam member 1210 by the elastic force of the spring member 1240, The rotation of the first link member 200 relative to the first main body 10 can be elastically realized in a semiautomatic manner.

When the rotation of the first link member 200 relative to the first main body 10 is progressed to a certain degree or more, the second actuator 1200 moves beyond the turning point of the driven cam member 1220 The initial rotation of the first link member 200 with respect to the first body 10 can be realized by the elastic force of the first actuator 1100 and the initial rotation of the first link member 200 with respect to the first body 10 can be realized, The elasticity of the first actuator 1100 and the elastic force of the second actuator 1200 act simultaneously, so that the first link member 200 can be elastically rotated.

Although the present invention has been described with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that
