Description

  The present invention relates to a tablet computer, and more particularly, a sliding and tilting tablet computer in which a second main body can continuously perform sliding movement and tilting movement with respect to a first main body. About.

  Recently, with the development of technology, various types of personal computers (PCs) have been developed and marketed. Among them, a tablet computer has recently been attracting attention as a portable computer that has developed in a direction that combines the performance of a notebook and the mobility of a PDA (Personal Digital Assistant).

  In general, a tablet computer allows a user to save specified data or convert it into text and input it to other application programs by writing directly on the screen using an electronic pen and input board utility. In addition to input, you can use an electronic pen to perform tasks that are generally performed with a mouse or keyboard (open application programs, select text, display menus, etc.), or use an existing mouse or keyboard. It has a configuration.

  However, because of the structural characteristics of conventional tablet computers, it is difficult to place them on a desk or shelf so that they stand upright or tilt. There is a troublesome and inconvenient problem that it is necessary to grasp and use it.

  In particular, when watching videos or making video calls for a relatively long time, there is a problem that it is difficult to maintain the orientation of the display unit at a constant level. To maintain the angle of the tablet computer constant, a separate deferment is required. There is the complication of having to use a table or case.

  Therefore, recently, various studies have been made on tablet computers that provide convenience in use and use and can maintain the directionality of the display unit at a constant level.

  The tablet computer capable of sliding and tilting according to the present invention can be simplified in structure and can provide convenience in use.

  In the tablet computer capable of sliding and tilting according to the present invention, the second main body can continuously perform the sliding movement and the tilting movement with respect to the first main body. The distance between the first main body and the second main body can be minimized when the main body is opened and closed.

  The tablet computer capable of sliding and tilting according to the present invention can improve operational stability and reliability, and can create an excellent aesthetic appearance during the tilting operation.

  The tablet computer capable of sliding and tilting according to the present invention can buffer an impact force generated during opening and closing operations.

  In addition, the tablet computer capable of sliding and tilting according to the present invention can improve stability and reliability, and can extend its life.

  According to a preferred embodiment of the present invention for achieving each of the above-mentioned objects of the present invention, a tablet computer includes a first main body, and a second main body arranged to be superimposed on the first main body. One end is rotatably connected to the first body, the other end is rotatably connected to the second body, and one end is slidably and rotatably connected to the first body. A second link member rotatably connected to the second body, one end rotatably connected to the first link member, and the other end rotatably connected to the second link member. A connecting link member, and a damping part that provides a damping force for decelerating the moving speed of the second body in at least a part of the opening / closing section of the second body relative to the first body, When the link member 1 rotates, Thus, the distance between the second link member and the first link member is limited within a predetermined distance, and the second body continuously performs sliding movement and tilting movement on the first body. It is opened and closed.

  For reference, in the present invention, the first main body and the second main body are understood as the main body housing (or case) constituting a normal tablet computer, or are manufactured separately from the main body. It can be understood as various connecting elements (for example, various plates, frames, etc.) coupled to the main body.

  In addition, an interface portion can be provided on the exposed surface of the first body that is exposed when the second body is opened. The interface unit may include at least one of a normal 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 element, and a speaker. Can be included. In addition, a normal additional device can be used as the interface unit, and the present invention is not limited or limited by the type and characteristics of the interface unit.

  The position, number, and separation interval of each link member can be changed as appropriate according to required conditions and design specifications. When the second body is closed, each link member is connected to the first body and the second body. It can arrange | position substantially parallel between main bodies. Of course, depending on the case, each link member can be disposed so as to be inclined between the first main body and the second main body when the second main body is closed.

  In addition, in the present invention, each link member is rotatably connected to the corresponding other link member or the main body so that the link member is mediated by ordinary shaft means such as a rotation pin, a rotation protrusion, and a rotation shaft. It can be understood to mean that it is rotatably coupled to another corresponding link member and body.

  A guide plate can be coupled to the back surface of the second main body, and the other end of the first link member and the other end of the second link member are rotatably coupled to the guide plate to form a module together with the guide plate. Can be Depending on the case, the other ends of the first and second link members may be directly coupled to the second body, or only one of the first and second link members may be a guide plate or the like. It can comprise so that it may couple | bond with a 2nd main body through the separate member of these.

  In addition, one end of the second link member is slidably connected to the first main body so as to be slidable and rotatable. For this purpose, one end of the second link member is slidably moved and rotated to the first main body. Guide rails can be formed for possible accommodation. As an example, a guide bracket can be coupled to the first body, and a guide rail can be formed on the guide bracket. Depending on the case, the guide rail may be formed directly on the first body.

  The section in which the damping force by the damping unit acts can be changed as appropriate according to the required conditions and design specifications. As an example, the damping force by the damping unit only in a part of the opening / closing section of the second main body (for example, a section adjacent to at least one of the points where the opening and closing of the second main body is completed). In some cases, the damping force by the damping part may be applied over the entire opening / closing section of the second main body.

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

  In addition, the damping part can be coupled to at least one of the first link member and the second link member, and mechanically interlocks with the rotation of the first link member and the second link member. In addition, a damping force can be provided to the first link member and the second link member. As an example, the damping part includes a damping protrusion formed on at least one of the first link member and the second link member, a damping housing provided to the first body, and a linear movement to the damping housing. The damping rod may be provided so as to be able to come into contact with the damping protrusion, and the damping spring may be configured to provide an elastic force so that the damping rod elastically contacts the damping protrusion. Depending on the case, a damping housing may be mounted on the first link frame (or the second link frame), and a damping protrusion may be formed on the first main body.

  The shape and size of the damping protrusion can be appropriately changed according to required conditions and design specifications. As an example, a shaft coupling portion for shaft coupling with the first body can be formed at one end of the first link member, and the damping protrusion is formed by partially removing the shaft coupling portion. be able to. For example, the damping protrusion can be formed in a substantially “C” shape having an opening on the side surface. The length and shape of such an opening can be variously changed according to required conditions and design specifications. According to circumstances, the damping protrusion may be formed to have a plurality of openings. You can also. In addition, a damping guide may be provided at an end of the damping rod, and the damping rod may contact the damping protrusion through the damping guide.

According to the tablet computer capable of sliding and tilting according to the present invention, the structure can be simplified and the convenience in use can be provided.
In particular, according to the present invention, when the first link member is rotated, the connection link member limits the distance between the second link member and the first link member within a predetermined distance. The main body can continuously perform the sliding movement and the tilting movement on the first main body, and the opening / closing operation can be performed more easily.

  In addition, according to the present invention, when the second body is opened and closed with respect to the first body, the second link member is pulled and pushed by the connecting link member, so that the second body is opened and closed. By rotating the lower end of the main body in a direction approaching the upper surface of the first main body, the second main body is lifted with respect to the first main body when the second main body is opened and closed (the lower end of the second main body The distance between the upper surface of the first main body and the first main body can be minimized, and the operational stability and reliability can be improved.

  In addition, according to the present invention, when the second main body is opened and closed, the phenomenon of the second main body lifting relative to the first main body can be minimized, so that the force required for the opening and closing operation can be effectively transmitted. As an example, the direction in which the force is applied during the opening / closing operation can be a substantially straight line, so there is no need to change the direction in which the force is applied or the strength of the force has to be changed. can do.

  In addition, according to the present invention, the lifting phenomenon of the second main body relative to the first main body can be minimized, so that an excellent aesthetic appearance can be created during the opening and closing operation, and convenience in use can be provided. That is, there is a problem that the larger the distance between the first main body and the second main body during the opening / closing operation, the less aesthetically pleasing the opening / closing operation becomes and the more inconvenient. However, according to the present invention, since the tilting operation can be implemented in a state in which the separation distance between the first main body and the second main body is minimized, it is possible to create a beautiful appearance with the convenience of opening and closing. .

  Furthermore, according to the present invention, the second main body can be tilted while being slid with respect to the first main body. In other words, the second main body is opened and closed with the second main body slightly floated with respect to the first main body. Therefore, it is possible to prevent interference between the second main body and the first main body, and it is not necessary to employ a separate structure for preventing mutual interference between the main bodies.

  According to the present invention, the moving speed of the second main body can be reduced by the damping force of the damping portion when the second main body is opened and closed, and the impact force at the moment when the opening or closing of the second main body is completed is obtained. Can be buffered. Therefore, the opening / closing operation of the second main body can be implemented flexibly without impact, the product can be prevented from being damaged or broken by the impact force, and the life can be extended.

  Further, according to the present invention, the section in which one end of the second link member slides does not need to be formed over the entire section of the first main body, and can be partially formed only in the specific section. The exposed area (for example, keypad area) of the first main body that is exposed when the main body is opened can be secured more widely, and the space utilization and design flexibility of the tablet computer can be improved.

  In addition, according to the present invention, since the interface portion exposed on the upper surface of the first main body can be used when the second main body is opened, various input / output functions can be performed, and a separate stationary table or case can be used. At least the angle of the display unit can be kept constant.

  Further, according to the present invention, the second main body can be automatically tilted and released by a simple opening operation of the user. That is, there is no trouble of performing separate slide operation and tilting operation in parallel to release the second main body, and at the same time the restriction by the restricting portion is released by the linear operation of the operation member. By automatically tilting the main body, it is possible to provide convenience in use.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. For reference, in the present description, the same numbers indicate substantially the same elements, and can be described with reference to the contents described in other drawings under the above rules, and are considered obvious to those skilled in the art. The contents that are repeated or repeated can be omitted.

  1 to 3 are perspective views for explaining the structure of a tablet computer capable of sliding and tilting according to the present invention.

  As shown in FIGS. 1 to 3, the tablet computer 100 capable of sliding and tilting according to the present invention includes a first main body 10, a second main body 20, a first link member 200, and a second link member. 300, a connecting link member 400 and a damping part.

  For reference, in the present invention, the first main body 10 and the second main body 20 are understood as the main body housing (or case) constituting a normal tablet computer, or manufactured separately from the main body. It can be understood as various connecting elements (for example, various plates, frames, etc.) that are coupled to the main body.

  As an example, the first main body 10 may include a front case (not shown) and a rear case (not shown) that form a predetermined accommodation space inside in a cooperative manner. An interface unit 12 for inputting / outputting various information can be provided on the front surface of the case.

  For reference, the interface unit 12 may include at least one of a normal 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 element, and a speaker. Can be included. In addition, a normal additional device can be used as the interface unit 12, and the present invention is not limited or limited by the type and characteristics of the interface unit 12. For example, as the interface unit, a QWERTY keypad having a QWERTY layout, which is an English standard keyboard, can be applied to the front surface of the first main body. A game keypad, a touchpad, and the like for inputting signals related to the can be appropriately arranged.

  The second main body 20 may be configured to include a front case (not shown) and a rear case (not shown) that form a predetermined accommodation space therein. May include a display unit 22 for outputting video information.

  In addition, the second main body 20 has a predetermined angle while drawing a predetermined trajectory with respect to the first main body 10 through the first link member 200, the second link member 300, and the connecting link member 400. Configured to be only tilted.

  In the following, one first link member 200 and one second link member 300 are provided in the substantially central portion of the first main body 10 (or the second main body), respectively, and the first link member 200 ( (Or, the second link member) will be described with an example in which the connecting link members 400 are provided at both end portions. Depending on the case, the first link member, the second link member, and the connection link member may be provided one by one, or the first link member, the second link member, and the connection link member may be provided at predetermined intervals. A plurality of link members 200, 300, and 400 may be provided so as to be spaced apart from each other, and the present invention is not limited or limited by the position, number, and separation interval of each link member 200, 300, 400.

  One end of the first link member 200 is rotatably connected to the first main body 10 and the other end is rotatably connected to the second main body 20. The shape and structure of the first link member 200 can be variously changed according to required conditions and design specifications. As an example, the first link member 200 may be provided in the shape of a square plate having a predetermined size. Depending on the case, the first link member may be formed in a rod shape having a length longer than the width.

  In addition, when the second main body 20 is closed with respect to the first main body 10, the first link member 200 can be disposed substantially in parallel between the first main body 10 and the second main body 20. . The structure for arranging the first link members 200 in parallel can be variously changed according to required conditions and design specifications. As an example, at the time of side projection, a first shaft coupling portion for rotational coupling with the first main body 10 can be formed at the right end portion of the first link member 200. A second shaft coupling portion (not shown) for rotational coupling with the second main body 20 can be formed at the left end portion of the 200. The first shaft coupling portion 201 can be formed to have a rotation center at a position relatively lower than the first link member 200. In some cases, the first and / or second shaft coupling need not have a low (or high) center of rotation relative to the first link member, and / or one end of the first link member. It is also possible to provide the other end itself in a form bent by a predetermined angle with respect to the central portion.

  One end of the second link member 300 is connected to the first main body 10 so as to be slidable and rotatable, and the other end is connected to the second main body 20 so as to be rotatable. The shape and structure of the second link member 300 can be variously changed according to required conditions and design specifications. Hereinafter, the second link member 300 is smaller than the first link member 200. An example provided in the form of a plate having a size will be described. The second link member 300 can also be formed in a rod shape having a length longer than the width according to required conditions and design specifications.

  When the second body 20 is closed with respect to the first body 10, the second link member 300 is substantially parallel between the first body 10 and the second body 20 together with the first link member 200. Can be arranged. Similar to the first link member 200 described above, the second link member 300 is closed by appropriately changing the rotation center of the shaft coupling portion or by making the heights of both ends of the second link member different. Sometimes they can be placed in parallel.

  Of course, depending on the case, the first link member and the second link member may be disposed so as to be inclined between the first main body and the second main body when the second main body is closed. The first link member and the second link member are parallel to each other when the second body is closed so that the space occupied by the first link member and the second link member can be minimized and the tablet computer can be made slimmer. It is preferable to arrange.

  In addition, a guide plate 24 can be coupled to the back surface of the second main body 20, and the other end of the first link member 200 and the other end of the second link member 300 rotate to the guide plate 24. It can be modularized with the guide plate 24 by possible coupling.

  In addition, in the present invention, the first link member 200 and the second link member 300 are connected to the corresponding first main body 10 and second main body 20 so as to be rotatable. In addition, the first link member 200 and the second link member 300 are rotatably coupled to the corresponding first main body 10 and second main body 20 through a normal shaft means such as a rotation shaft. Then you can understand.

  One end of the connection link member 400 is rotatably connected to the first link member 200, and the other end is rotatably connected to the second link member 300. That is, the connecting link member 400 connects the first link member 200 and the second link member 300 to each other, and the second link member is rotated when the first link member 200 is rotated with respect to the first main body 10. By sliding the one end of 300 in a direction approaching one end of the first link member 200 and a direction away from one end of the first link member 200, the second main body 20 is moved relative to the first main body 10 during opening and closing. The floating phenomenon (the separation distance between the lower end portion of the second main body 20 and the upper surface of the first main body 10) can be minimized.

  The shape and structure of the connecting link member 400 can be variously changed according to required conditions and design specifications. As an example, the connection link member 400 may be provided in a straight line shape having a predetermined length, and may be provided in a shape bent by a predetermined angle or an arc shape depending on the case. In the following, one end of the connecting link member 400 formed in a linear form is rotatably connected so as to be adjacent to one end of the first link member 200, and the other end of the connecting link member 400 and the second link member 300 are connected. An example will be described in which one end is connected via the same shaft means and connected so as to have the same rotation center. Depending on the case, it is also possible to configure the other end of the connecting link member to have a different rotation center from the one end of the second link member.

  In addition, a guide case 210 having a receiving portion 212 can be coupled to the upper surface of the first main body 10, and the first link member 200 is in a closed state of the second main body 20 with respect to the first main body 10. The second link member 300 and the connecting link member 400 can be accommodated in the accommodating portion 212.

  With this configuration, when the second main body 20 is opened with respect to the first main body 10, one end of the second link member 300 is pulled to the one end of the first link member 200 while being pulled by the connecting link member 400. When the second body 20 is closed with respect to the first body 10, one end of the second link member 300 is pushed by the connecting link member 400 when the second body 20 is closed. It can move in a direction away from one end of 200. Thus, in a state where the lower end portion of the second main body 20 is disposed adjacent to the upper surface of the first main body 10 by pulling and pushing the one end of the second link member 300 by the connecting link member 400. The second body 20 can be opened and closed with respect to the first body 10.

  The tablet computer 100 may include an actuator 700 for providing a driving force so that the opening and closing of the second body 20 with respect to the first body 10 can be realized in an automatic or semi-automatic manner. As an example, the actuator 700 may be configured to provide a driving force for semi-automatic opening and closing of the second body 20 with respect to the first body 10, and the actuator 700 includes the first body 10 and the first body 10. Providing a driving force to at least one of the first link member 200 and the second link member 300 during rotation of the first link member 200 and the second link member 300 with respect to the two main bodies 20. Can do. Hereinafter, an example in which the actuator 700 is configured to provide an elastic force to the first link member 200 when the first link member 200 rotates with respect to the first main body 10 will be described.

  As the actuator 700, various normal actuators 700 can be used according to required conditions and design specifications. As an example, the actuator 700 may be a hinge module that is generally used in a normal folder type personal portable terminal. The actuator 700 may include a driven cam member (not shown), a drive cam member (not shown), and a spring member (not shown).

  The driven cam member is provided to move linearly along a shaft provided to the first body, and a driven cam profile is formed on one surface of the driven cam member. Such a driven cam profile can be configured by alternately arranging valleys and peaks having a height difference along the axial direction of the shaft.

  The drive cam member is connected to one end of the first link member, and includes a drive cam profile corresponding to the driven cam profile of the driven cam member, and is configured to interact while contacting the driven cam member. The

  The spring member provides an elastic force so that the driven cam member moves in a direction approaching the drive cam member. The structure and type of the spring member can be variously changed according to required conditions and design specifications. As an example, an example in which a normal coil spring is used as the spring member will be described.

  As described above, the driven cam member can be elastically contacted with the driving cam member by the elastic force of the spring member, but the driven cam member is caused by the interaction between the driven cam member and the driving cam member by the elastic force of the spring member. This linear motion can be converted into an elastic rotational motion, and the rotation of the first link member relative to the first main body can be elastically performed in a semi-automatic manner by this force.

  Meanwhile, one end of the second link member 300 is connected to the first main body 10 so as to be slidable and rotatable. For this reason, the first main body 10 is connected to one end of the second link member 300. The guide rail 630 for accommodating the link pin 310 provided in the slidable and rotatable is formed.

  Hereinafter, an example in which a guide bracket 600 is coupled to the first main body 10 and the guide rail 630 is formed on the guide bracket 600 will be described.

  The guide bracket 600 may include an upper bracket 610 and a lower bracket 620 that form guide rails 630 in a cooperative manner, and one end of the first link member 200 is rotatably coupled to the guide bracket 600. Thus, the guide bracket 600 can be modularized.

  The guide bracket 600 may be formed with a receiving portion (not shown) for receiving one end of the actuator 700. The first link member 200, the second link member 300, and the connecting link described above. The member 400 and the actuator 700 can be provided together with the guide bracket 600 as a module.

  On the other hand, in the structure in which the second main body 20 is tilted with respect to the first main body 10, the rear connection portion between the first main body 10 and the second main body 20 is directly exposed to the outside so that the external appearance is obtained. There is a problem that becomes complicated. However, in the present invention, when the second main body 20 is opened with respect to the first main body 10, the rear connection portion between the first main body 10 and the second main body 20 can be covered with the first link member 200. Therefore, a neat and beautiful appearance can be created. For this, the first link member 200 is provided to have a relatively larger size or area than the second link member 300 and the connection link member 400, and the second link body 200 is opened when the second body 20 is opened. The link member 300 and the connecting link member 400 can be hidden by the first link member 200 without being directly exposed to the outside.

  The damping unit is provided to provide a damping force for decelerating the moving speed of the second body 20 in at least a part of the opening / closing section of the second body 20 with respect to the first body 10.

  The section in which the damping force by the damping section acts can be changed as appropriate according to the required conditions and design specifications. Hereinafter, the damping force acts only in a part of the opening / closing section of the second main body 20 (for example, a section adjacent to at least one of the points where the opening and closing of the second main body is completed). An example of the configuration will be described. Depending on the case, the damping force by the damping part may be applied over the entire opening / closing section of the second main body.

  As the damping unit, various ordinary damping devices can be used according to required conditions and design specifications, and the present invention is not limited or limited by the structure and characteristics of the damping unit. As an example, the damping unit may be configured to provide a damping force using at least one of frictional resistance, fluid resistance, and spring resistance. For reference, the damping force using the fluid resistance may include a damping force due to viscous resistance generated when the damping member moves or rotates inside a normal working fluid such as grease or silicone oil.

  The damping part can be connected to at least one of the first link member 200 and the second link member 300, and the mechanism is operated by the rotation of the first link member 200 and the second link member 300. In conjunction with each other, a damping force can be provided to the first link member 200 and the second link member 300. Here, the fact that the damping part is mechanically interlocked by the rotation of the link members 200 and 300 means that the damping part is operated by contact, friction or interference caused by the rotation of the first link member 200 and the second link member 300. Can be understood to mean.

  Hereinafter, an example in which the damping portion includes the damping protrusion 510, the damping housing 520, the damping rod 530, and the damping spring 550 will be described.

  The damping protrusion 510 may be formed on at least one of the first link member 200 and the second link member 300. Hereinafter, the damping protrusion 510 is formed on one end of the first link member 200. An example will be described. In addition, a damping force can be applied by a later-described damping rod 530 elastically contacting the damping protrusion 510.

  The shape and size of the damping protrusion 510 can be appropriately changed according to required conditions and design specifications. For example, the first link member 200 may be formed with a first shaft coupling portion 201 for shaft coupling with the first body 10 at one end of the first link member 200. The portion 201 can be formed by partially removing.

  Hereinafter, an example in which the damping protrusion 510 is formed by partially removing the first shaft coupling portion 201 and formed in a “C” shape having an opening 512 on a side surface will be described. In addition, in a closed state of the second main body 20, an end portion of a damping rod 530 described later can be accommodated in the opening portion 512, and in a state where the end portion of the damping rod 530 is disposed in the opening portion 512. The contact between the damping rod 530 and the damping protrusion 510 can be released. Here, the release of the contact between the damping rod 530 and the damping protrusion 510 can be understood to mean a state in which the damping force due to the contact between the damping rod 530 and the damping protrusion 510 does not act. The length of the opening 512 can be appropriately changed according to required conditions and design specifications, and the point in time when the damping force acts can be changed according to the length of the opening 512.

  In the embodiment of the present invention, an example in which the damping protrusion is configured to have one opening is described. However, depending on the case, the damping protrusion may be formed to have a plurality of openings. The present invention is not limited or limited by the number and shape of the openings.

  The damping housing 520 can be attached to the first body 10 so as to be adjacent to the damping protrusion 510, and the damping rod 530 is provided to the damping housing 520 so as to be linearly movable and can be in contact with the damping protrusion 510. Can be arranged. For example, the damping protrusion 510 may be mounted in the damping housing 520 so as to be linearly movable. However, depending on the case, the damping rod may be mounted on the outside of the damping housing.

  In the embodiment of the present invention, an example in which the damping rod 530 is formed in a rod shape having a predetermined length is described. However, the shape and structure of the damping rod 530 may be variously changed according to the damping condition. can do.

  In addition, a damping guide 540 may be provided at an end of the damping rod 530, and the damping rod 530 may contact the damping protrusion 510 through the damping guide 540. The damping guide may be configured to be in line contact or point contact along the surface of the damping protrusion, and according to circumstances, the damping guide may be configured to be in surface contact along the surface of the damping protrusion. Is possible.

  The damping guide 540 can be formed of a normal plastic material, but it is required to use a material that has excellent mechanical, thermal, and chemical properties even in a wide range of operating temperatures over a long period of time and has excellent dimensional stability. Therefore, it is preferable to use a lubricating material having excellent self-lubricating properties and excellent fatigue resistance properties such as polyacetal, polyamide and polyamideimide.

  In addition, the mounting portion 640 for mounting the damping housing 520 can be formed on the guide bracket 600 described above, and the damping housing 520 can be modularized together with the guide bracket 600.

  In the embodiments of the present invention described above and shown in the drawings, an example in which a damping projection is formed on the first link frame and a damping housing or the like is mounted on the first main body is described. On the other hand, a damping housing can be mounted on the first link frame, and a damping protrusion can be formed on the first body. Further, in the embodiment of the present invention, an example in which the damping rod is configured to come into contact with the damping protrusion through the damping guide is described, but depending on the case, the end of the damping rod may be It can also be configured to be in direct contact with the damping protrusion.

  The damping spring 550 provides an elastic force so that the damping rod 530 can elastically contact the damping protrusion 510. As an example, a normal coil spring may be used as the damping spring 550, and the damping spring 550 is interposed between the damping housing 520 and the damping rod 530 and elastically supports the damping rod 530. be able to.

  Hereinafter, the operation structure of the tablet computer capable of sliding and tilting according to the present invention will be described.

  4 to 7 are views for explaining an operation structure of a tablet computer capable of sliding and tilting according to the present invention. In addition, the same or identical parts as those in the above-described configuration are denoted by the same or identical reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 4, in the initial state (closed state), the first main body 10 and the second main body 20 are arranged so as to overlap each other. At this time, the first link member 200, the second link member 300, and the connecting link member 400 are arranged in a folded state so as to overlap each other between the first main body 10 and the second main body 20. Is done. As described above, the user can input or output various information using the display unit 22 provided in the second main body 20 in the initial state.

  Thereafter, in order to use the tablet computer with the second main body 20 opened relative to the first main body 10, the user pushes up the second main body 20 as shown in FIGS. The second body 20 can be opened with respect to the first body 10. That is, when the lower end of the second main body 20 is pushed up, the first link member 200 and the second link with respect to the first main body 10 are pushed in the same manner as in the method in which the slide portion is slid open with a normal slide type personal portable terminal. By rotating the link member 300, the second main body 20 can be slid relative to the first main body 10 and simultaneously rotated by a predetermined angle to be tilted open. As described above, when the second main body 20 is opened, various information can be input or output using the interface unit 12 exposed on the upper 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, but when the opening of the second main body 20 is advanced more than a certain amount, the damping unit By operating and a damping force acting on the first link member 200, the moving speed of the second main body 20 can be decelerated. That is, as shown in FIG. 6, when the rotation of the first link member 200 is advanced by a certain amount or more, the damping protrusion 510 can come into contact with the damping rod 530, and the damping rod 530 comes into elastic contact with the damping protrusion 510. The rotational speed of the first link member 200 can be decelerated by the damping force generated by doing so. Therefore, the opening movement speed of the second main body 20 can be reduced by such a damping force.

  In the same manner as in the above-described opening, one end of the second link member 300 is separated from one end of the first link member 200 while being pushed by the connecting link member 400 even when the second main body 20 is closed. Since the second main body 20 can be lifted with respect to the first main body 10 at the time of closing, the closing movement speed of the second main body 20 can be reduced by the damping portion.

  8 to 10 are diagrams illustrating a tablet computer capable of sliding and tilting according to another embodiment of the present invention. In addition, parts that are the same as or the same as those in the configuration described above are given the same or the same reference numerals, and detailed descriptions thereof are omitted.

  Referring to FIGS. 8 to 10, according to another embodiment of the present invention, a tablet computer includes a restraint part for temporarily restraining the closed state of the second body 20 with respect to the first body 10, and the restraint part. And the first actuator 1100 that provides an elastic force so that the second body 20 is automatically released when the restraint by the restraint is released, and when the restraint by the restraint part is released, The second body 20 can be automatically opened by the elastic force of the first actuator 1100.

  More specifically, the first actuator 1100 can provide an elastic force so as to rotate in the direction in which the first link member 200 rises with respect to the first body 10. Types and characteristics can be changed in various ways according to required conditions and design specifications. For example, a normal torsion spring can be used as the first actuator 1100, and the first actuator 1100 is configured so that the first link member 200 always rotates with respect to the first main body 10. Elastic force can be provided.

  The restraining portion is provided to temporarily restrain the closed state of the second body 20 with respect to the first body 10. Here, the restriction of the closed state of the second main body 20 with respect to the first main body 10 means that the rotation of the first link member 200 (and the second link member) with respect to the first main body 10 is restricted. Can be understood to mean a state.

  The restraining part may be provided with various structures that can temporarily restrain the closed state of the second body 20 with respect to the first body 10. As an example, an example in which the restraining portion includes an operation member 910, a restraining protrusion 920, and a locking member 932 will be described.

  The operation member 910 can be provided in various ways that can be linearly operated on the first main body 10 according to required conditions and design specifications. As an example, the operation member 910 can be provided on the side surface of the first main body 10 so as to be pushed by a push method. Depending on the case, the operation member can be provided on the front surface or the rear surface of the first main body so as to be linearly operable, or the operation member can be provided on the second main body.

  The restraining protrusion 920 may be provided on at least one of the first link member 200 and the second link member. As an example, the restraining protrusion 920 may be formed on the bottom surface of the first link member 200, and restraining the rotation of the first link member 200 relative to the first body 10 by restraining the restraining protrusion 920. Can do.

  The locking member 932 includes a restraining groove 932a for restraining the restraining protrusion 920. The locking member 932 selectively releases the restraining protrusion 920 and the restraining position for restraining the restraining protrusion 920 while interlocking with the operation member 910. It can be configured to move linearly elastically to the position. As an example, the locking member 932 is connected to the operation member 910 and can move linearly in the same direction as the operation member 910 and can be elastically supported by a normal elastic member 934 such as a spring. In the state where the locking member 932 is disposed at the restraining position, the restraining protrusion 920 is housed and restrained in the restraining groove 932a, so that the rotation of the first link member 200 with respect to the first body 10 can be restrained. When the locking member 932 is disposed at the release position, the rotation of the first link member 200 with respect to the first main body 10 can be allowed by pulling out the restraining protrusion 920 from the restraining groove 932a.

  In the above-described and illustrated embodiments of the present invention, the operation member 910 is described as being provided so that it can be pushed by the push method along the same direction as the movement direction of the locking member 932. Accordingly, the operating member can be provided so as to be slidable along a direction intersecting the moving direction of the locking member (for example, the longitudinal direction of the first main body), and the locking member can be provided by sliding operation of the operating member. It is also possible to configure so that the two move linearly in conjunction with each other. Further, depending on the case, it is possible to form a restraining groove on the first link member (or the second link member) and form a restraining projection on the locking member.

  In addition, the second main body 20 may include a second actuator 1200 that provides an elastic force so that the second main body 20 is elastically opened. Of course, when the restraint of the restraint portion is released only by the elastic force of the first actuator (or the second actuator), the second body can be automatically opened. When only the first actuator is used alone, there is a problem that the thickness and diameter of the actuator (spring or cam member) are inevitably increased in order to ensure a certain level of elastic force. May be adversely affected. However, in the present invention, by using both the first actuator 1100 and the second actuator 1200, sufficient elastic force can be provided without an increase in thickness and size, and the second body 20 can be provided. The elastic release can be realized stably.

  The structure and characteristics of the second actuator 1200 can be variously changed according to required conditions and design specifications. For example, the second actuator 1200 may rotate the first link member 200 with respect to the first body 10 when the rotation of the first link member 200 with respect to the first body 10 is advanced by a certain amount or more. The elastic force can be provided. Hereinafter, an example in which the second actuator 1200 includes the drive cam member 1210 and the driven cam member 1220 will be described. Depending on the case, the second actuator can be connected to the second link member, or can be connected to the first and second link members independently.

  The driving cam member 1210 is connected to the first link member 200 and can rotate integrally with the first link member 200. As an example, a drive cam profile (not shown) can be formed at both ends of the drive cam member 1210, and the shape and structure of the drive cam profile vary depending on required conditions and design specifications. Can be changed. As an example, the drive cam profile may be provided in a form in which valleys and peaks having a height difference along the axial direction are alternately arranged. In some cases, a drive cam profile is formed only at one end of the drive cam member, and only one driven cam member, which will be described later, can be used.

  The driven cam member 1220 includes a driven cam profile (not shown) having a turning point. The driven cam member 1220 is provided at both ends of the driving cam member 1210 and interacts with the driving cam member 1210 while being in elastic contact. Configured. As an example, a housing 1230 can be coupled to both ends of the drive cam member 1210, and the driven cam member 1220 moves linearly along the inside of the housing 1230 and interacts while contacting the drive cam member 1210. be able to.

  A spring member 1240 may be provided in the housing 1230 to provide an elastic force so that the driven cam member 1220 moves in a direction approaching the driving 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 an elastic rotational motion by the interaction between the driven cam member 1220 and the drive cam member 1210 due to the elastic force of the spring member 1240. By this force, The rotation of the first link member 200 relative to the main body 10 can be elastically implemented in a semi-automatic manner.

  In addition, when the rotation of the first link member 200 with respect to the first main body 10 is advanced more than a certain amount, the second actuator 1200 has an elastic force due to the drive cam member 1210 exceeding the turning point of the driven cam member 1220. However, 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 rotation of the first link member 200 can be realized. When advanced beyond a certain level, the elastic force of the first actuator 1100 and the elastic force of the second actuator 1200 act simultaneously, whereby the first link member 200 can elastically rotate.

  As described above, the present invention has been described with reference to the preferred embodiments, but those skilled in the art will not depart from the spirit and scope of the present invention as described in the following claims. It will be understood that various modifications and changes can be made to the present invention within the scope.
