The present invention relates to a support device for a display module, a display device for a notebook, and a notebook computer.

The display module is a device that provides an image and has various forms according to a method of operation. Among them, the liquid crystal module has been continuously developed and can operate as a thin film having a large surface, so that the use thereof has increased rapidly in recent years. Such a liquid crystal module is mainly used as a display module of a notebook computer because it can realize an image even with a thin thickness.

The notebook computer includes a main body in which a keyboard is arranged and various components are accommodated therein, and a display unit which can rotate about the main body. The thinner the display unit, the thinner the overall thickness, including the thickness of the liquid crystal module accommodated therein, is more convenient to use and carry the notebook computer.

However, the thinner the thickness of the display part, the weaker the strength of the display part is. Therefore, the external force applied when the display part is opened and closed affects the liquid crystal module. In detail, when one side of the cover is pressed while opening the display unit, the cover does not oppose itself against the pressed pressure and the cover is deformed. The deformation of the cover is eventually transmitted to the liquid crystal module and affects the liquid crystal layer inside the liquid crystal module, thereby generating a poodle phenomenon (PUDDLE phenomenon) in which fine wrinkles are generated on the screen of the liquid crystal module. If the impact amount is large, the force applied to the liquid crystal module may be large, resulting in a problem that the liquid crystal module is damaged.

In order to solve such a problem, a structure for interposing a cushion between the cover and the liquid crystal module has been proposed, but the process of intervening the cushion is cumbersome, and the size of the display unit is increased so as to provide an interval for the cushion to intervene. There is a problem that grows, there is a problem that can not perform its function when the cushion is aging.

As another method, there is a method in which the appearance of the cover covering the liquid crystal module is complicated to increase the cover's own strength so that the cover is not deformed even when external force is applied, so that the liquid crystal module is not affected. . However, this method is not preferable because it deteriorates the image of the product because it damages the appearance of the display unit.

The present invention is proposed under the background described above, and a display device supporting device which prevents abnormality of the screen of the liquid crystal module by external force applied to the display unit, and furthermore, prevents damage of the liquid crystal module by force applied from the outside. A display device of a notebook is proposed.

A display device supporting device according to the present invention, the front cover and the rear cover that is accommodated inside the display module; And a first hook provided at one of the front cover and the rear cover, the first hook being provided at an edge portion and a hanging portion at an end portion thereof. In another one of the front cover and the rear cover, a second hook is provided at a position corresponding to the position at which the first hook is provided, and a second hook is provided to prevent bidirectional movement of the insertion / release of the hanging portion.

Display device of a notebook according to the invention, the display module; A front cover and a rear cover respectively protecting the front and the rear of the display module; And a front hook formed on a rear surface of the corner portion of the front cover. A rear hook provided on a front surface of the rear cover at a position corresponding to the front hook; And a stop provided at at least one of the front hook and the rear hook to prevent movement in a direction in which the front hook and the rear hook are close to each other.

Notebook computer according to the invention, the main body; A display unit hinged to the main body and provided as a fastening structure of the front cover and the rear cover; And a double hook structure having a corresponding relationship provided at an edge portion of the cover for fastening the cover, wherein the double hook structure protrudes from one cover toward the other cover and hangs at an end thereof. Characterized in that the portion is a pair of hooks provided.

According to the present invention, the display module can be securely supported, and an effect of preventing an abnormality of the display unit generated during opening and closing of the display unit applied to the notebook can be obtained.

Hereinafter, specific embodiments to which the idea of the present invention is applied will be described in detail. However, the spirit of the present invention is not limited to the accompanying embodiments, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments included in the same idea by adding, changing, deleting, and adding components. It may be said, but this is also included in the spirit of the present invention.

1 is a perspective view of a notebook computer according to an embodiment of the present invention.

Referring to FIG. 1, a notebook computer includes a main body 1 in which a substrate, a storage medium, and the like are accommodated, a display unit 2 hinged to the main body 1, and pivoted with respect to the main body 1. And a hinge part 3 intervening the contact portion of the display part 2 and the main body 1 to allow a hinge movement of the display part 2.

The display unit 2 is provided in a form in which the liquid crystal module 6 is accommodated in an inner space defined by the front cover 4 and the rear cover 5, and in most cases, the front cover in order to have a beautiful appearance. The thickness t1 of is provided thinner than the thickness t2 of the rear cover. A latch 7 is provided at the upper end of the front cover 4 to fix the display unit 2 when the display unit 2 is closed. Here, the liquid crystal module 6 is a kind of display module. Hereinafter, the term "display module" and "liquid crystal module" are used together, but it is preferable to use the liquid crystal module 6, but any form of display module may be used. It can be understood as meaning.

The operation of opening the display unit 2 will be described.

First, the user lifts the display unit 2 by releasing the latch 7. At this time, the user is a right-handed user, while holding the "A" area of the display unit 2 with the right hand and lifted up, and the left-handed user is holding the "B" area to rotate the display unit 2 in general. In this case, since the direction in which the user applies the force is the direction in which the display unit 2 is opened, the force will be applied to the front cover 4. Then, the front cover 4 will be deformed by the external force of the user and there is a fear that a force is applied to the liquid crystal module 6 located near the "A" and "B" areas.

However, according to this embodiment, since the force applied to the front cover 4 is applied to the front cover 4 and the back cover 5 at the same time, the front cover 4 is not deformed, but in the original state. You can keep it as it is. This action will similarly occur when the user presses the rear cover 5 when the display unit 2 is closed, but the rear cover 5 has a lot of bends at the corners, so the strength is high, so that an external force is applied. Many variations will not occur even if they are lost.

Such an effect is achieved by the double hook structure provided on the front cover 4 and the rear cover 5 to face each other to fasten the front cover 4 and the rear cover 5 to each other. As the following, the double hook structure will be described in more detail.

2 is a perspective view of a supporting device of a display module according to the present embodiment.

Referring to FIG. 2, the display unit 2 of the notebook computer shown in FIG. 1 includes the front cover 4, the rear cover 5, and the inside of the cover 4 and 5 that have been described above. Included is a flat panel display module 6 which is exemplified as a liquid crystal module.

The fastening of each component mentioned above is demonstrated.

The display module 6 includes a hole 61 formed at a side of the module and a liquid crystal module fastening boss 51 formed at a side of the rear cover 5 to be aligned with a screw 52 inserted into the display module 6. It is fixed to the back cover 5 by the.

The front cover 4 and the rear cover 5 are fastened by two types of fastening methods, the first of which four corners of the covers 4 and 5 provided in a quadrangular shape are firmly fastened by screws. The second is a fastening method, and the second is a fastening method in which a double hook is provided at each corner of the quadrangle and the double hooks are fastened to each other. The locking fastening method is intended to ensure that the coupling between the two covers (4) (5) to the edge of the cover in consideration of the screw fastening method can not be provided as a whole on the edge of the cover. Have

The screw fastening method includes a hole 42 formed at four corners of the front cover 4, a cover fastening boss 53 formed at four corners of the rear cover aligned with the hole 42, and the A screw 41 is fastened together with the hole 42 and the cover fastening boss 53. In this way, the four corners of the cover 4, 5 can be firmly fastened to reinforce strength.

However, the entire corners of the covers 4 and 5 connecting the corner portions cannot be fastened by screws 41. Thus, such corner portions are provided with hooks to allow the covers 4 and 5 to be fixed to each other.

In this embodiment, the hook is characterized in that it is provided in a double hook structure. The double hook comprises a front hook 8 protruding rearward from the rear surface of the front cover 4 and a rear hook 9 protruding forward from the front of the rear cover 5. The front hook 8 and the rear hook 9 are collectively named double hooks because the hooks 8 and 9 are engaged in the same manner.

When the operation of the double hooks (8) and (9) is briefly described, the front hook (4) moves toward the rear cover (5) side and is fastened so that the front hook (8) is the rear hook ( 9) is fastened. The fastening between the hooks 8 and 9 is different from the fastening of the general hooks, so that they are provided in a similar shape to each other so that after the hooks are fastened to each other, any one hook, for example, the front hook 8 The rear hook 9 is hooked backwards, which further prevents further movement of the front hook 8.

As described above, after the pair of hooks 8 and 9 are engaged, if the front hook 8 is prevented from moving further backwards, the front cover 4 is likewise rearwarded. Movement is prevented. Therefore, even if the user presses the part where the hooks 8 and 9 are formed to open and close the display unit 2, the front cover 4 is attached to the rear cover 5 provided with the rear hook 9. Deformation is prevented by this. Looking at the phenomenon seen from the other side, the front cover (4) and the back cover (5) acts as a single body for the force pushed forward and rear by the double hook structure, serves to strengthen the strength. . Looking at another aspect, even if the front cover 4 is pushed before the front cover 4 touches the back cover (5) by a double hook structure before the display module (6), the front cover (4) It can be understood that the external force is not applied to the display module 6 by the pushing action. Of course, since the external force is not applied to the display module 6, problems such as screen abnormality of the display module 6 and damage of the display module 6 do not occur, and the effect of the present embodiment is to be realized. Can be achieved.

This action is more pronounced as the thickness of the display unit 2 becomes smaller and smaller in view of aesthetics. If the thickness of the front cover 8 becomes thinner among the pair of covers 8 and 9 constituting the display unit 2, an external force is applied to the front edge of the front cover 8 to open the notebook computer. It is more pronounced by the action of applying.

3 is a perspective view of a pair of hooks of the double hook structure according to the present embodiment.

3, the front hook 8 and the rear hook 9 are provided, and when the front cover 4 is fastened to the rear cover 5, the front hook 8 is the rear surface. Move to the hook (9) side. The figure shows the state just before the pair of hooks are fastened to each other.

In detail, the front hook 8 is provided in a hook shape as a whole, and extends rearward from the rear surface of the front cover 4 so as to cause deformation when the hook is engaged, and the extension 81. A hanging portion 82 which is provided at an end of the hook portion to perform a locking action, and defines an end side of the hanging portion 82, and transmits a force to which the front cover 4 is pushed to the rear cover 5 when the hook is engaged. Pushing portion 84 is provided. Of course, although not shown in Figure 3, the front hook 8 is preferably formed integrally on the rear surface of the front cover (4).

In addition, the rear hook 9 has a raised portion 91 provided to raise the height to a certain degree, a hanging portion 94 provided at an end of the rear hook 9, and at the lower side of the hanging portion. Pie is defined as a hook receiving portion 93 provided in the form, and the lower end of the hook receiving portion 93 and the stop portion 84 is in contact with the stop portion 92 to block the movement of the front hook (8) ) Is provided.

The operation of the double hook structure provided in the above configuration will be described in more detail.

As the hooks 8 and 9 approach, the sliding portions 83 and 95 provided together are first contacted, and the sliding portions 83 and 95 slide together so that the hook of the front hook 8 The portion 82 is inserted into the hook receptacle 93 past the hanging portion 94 of the rear hook 9. At this time, the extension portion 81 of the front hook 8 may be a certain degree of elastic deformation to enable the insertion of the hook. Then, a pair of faces corresponding to each other of the pair of hanging parts 82 and 94 provided on the hooks 8 and 9 are faced to each other.

As described, after the front hook 8 and the rear hook 9 are fastened to each other, when the user exerts an external force on the display unit 2 to move the display unit 2, the user pushes it. The front hook 8 adjacent to the part is pushed back. Then, before the front cover 4 exerts a force on the display module 6, the pushing portion 84 provided at the end of the front hook 8 touches the stop 92 of the rear hook 9. Then, the front hook 8 first pushes the rear hook 9, and the rear cover 5 is pushed by the rear hook 9. As a result, since the front cover 4 and the rear cover 5 locally act as a single body at the portion where the user applies the force, the strength is increased to be able to withstand more strongly without deformation by the external force of the user. .

On the other hand, the raised portion 91 is located on the bottom surface of the bottom cover 5, the stop portion 92 is located at a high level, for the interaction of the pushing portion 84 and the stop portion 92 To improve reliability. In addition, the raised portion 91 is to improve the strength of the rear cover 5, the rear hook 9 is provided, so that the strength at a specific point to apply the external force applied by the user in the end.

On the other hand, the width W2 of the back hook 9 is the width W1 of the front hook 8 so that the supporting action of the front hook 8 by the rear hook 9 is performed accurately. It is preferable to provide a large size as compared with the above. By providing in this way, the supporting action of the display module 6 can be accurately caused even by the manufacturing process tolerance and the shrinkage of the resin generated during molding.

4 is a cross-sectional view taken along line II ′ of FIG. 1, and referring to FIG. 4, the height H1 of the hanging portion 82 of the front hook 8 and the hook receiving portion of the rear hook 9 ( The height H2 of 93 and the height H3 between the stop 92 and the pusher 84 with the front hook 4 inserted are shown. The height H3 between the stop 92 and the pushing portion 84 is provided as a narrow gap, but the hanging portion 82 of the front hook 8 is inserted into the hook receiving portion 93. In order to be able to elastically deform afterwards, it is essential. However, since the height is a part which sets the limit which can be pushed when the front cover 4 is pushed backward, it is a matter of course that the height is as low as possible.

Therefore, when the user applies the external force F, the front hook 8 moves backward by the height H3 between the stop 92 and the pushing portion 84, but after that the front hook 4 It pushes the rear hook 5 by itself. In this case, the front cover 4 and the rear cover 5 are moved as a single unit, so that the deformation is not generated more firmly against the user's external force. In this case, the height H3 between the stop portion 92 and the pushing portion 84 is set to be shorter than the distance between the front cover 4 and the display module 6, so as not to affect any external force of the user. It is also desirable to have no effect on the display module 6 as well.

Meanwhile, referring back to FIG. 2, when the user opens and closes the display unit 2 in order to use the notebook computer, the user mainly applies force to the "A" area and the "B" area. Reflecting this phenomenon, it is preferable that the number of double hooks is increased in the "A" region and the "B" region as compared with the other regions. In the drawings, double hooks are formed twice as compared to other parts in the corresponding region.

In this manner, no external force is applied to the display module 6 even if the user applies an external force to any area of the display module as a whole, and thus the display module can be expected to have an advantage of preventing abnormalities of the display module and damage to the display module. . In addition, the double hook structure is more tightly coupled to the part to which the user mainly applies external force, so that the normal operation of the display module 6 can be maintained even when the position of the force applied by the user is slightly shifted.

In addition, in the above-described preferred embodiment, the double hook structure is provided as being coupled to each other a pair of hook structures provided on the bottom cover and the rear cover, but is not limited thereto. For example, the rear hook may be provided in a ring shape and serve as a stop 92 at a portion below a predetermined distance downwardly from which the hanging portion of the front hook 8 is inserted. As long as the stopper is provided as a separate part or an integrated part, the effects proposed in the present invention may be realized. However, it is natural that both are provided in the shape of a hook, which is more preferable in terms of convenience of production and increased strength.

In addition, in the above-described preferred embodiment, the front cover is provided with a front hook provided with an extension, and the rear cover has been described as being provided with a back cover provided with a raised portion, but is not limited thereto, and the extension is the rear hook. It may be formed in the and the embossment is provided in the front hook. However, since the front hook is usually a thin member is used, when a large area of the raised portion is provided, problems such as deformation may occur during the injection of the resin, the preferred embodiment described above is more preferable Of course.

In addition, in the preferred embodiment, the hook receiving portion is described as being provided to only one hook, but is not limited thereto. For example, the hook receiving portion and / or the raised portion may be provided in both the front hook and the rear hook, in which case the strength that can resist the external force of the user pushing the cover may be further increased. will be.
