In particular, notebook computers are downsized by various methods in order to meet the needs of the majority of users.
Most of the methods for downsizing a notebook computer involve investing a great deal of manpower and cost to study how to downsize the electronic components inside the laptop without changing the function. Therefore, even if the notebook personal computer is successfully downsized or the purpose is achieved, the time, manpower and cost required for this will be considerably high.

FIG. 1 is a three-dimensional schematic diagram of a conventional notebook computer.
The figure shows most notebook computers 1 at present, and is constructed by pivotally connecting a screen case 11 and a host case 13.
The screen case 11 has a front cover 111 and a rear cover 113, and the front cover 111 and the rear cover 113 cover the liquid crystal screen 115.
Two locking devices 2 are provided on the side edge portion of the screen case 11 away from the pivotally supported portion of the host case 13, and the host case 13 is also associated with the portions corresponding to the two locking devices 2, 2. Stop grooves 131 and 131 are recessed.
When the screen case 11 closes the lid corresponding to the host case 13, the two locking devices 2 are aligned with the corresponding locking grooves 131 to lock each other, thereby closing the notebook computer 1. Put it in a state.
The notebook personal computer 1 shown in FIG. 1 is provided with two locking devices 2 and 2 and two corresponding locking grooves 131 and 131. As another method, the center of the front edge of the notebook personal computer is used. In some cases, one locking device 2 is provided at a location, and one locking groove 131 corresponding to the locking device 2 is provided in the host case 13 to lock each other.

FIG. 2 is a three-dimensional exploded schematic view of a conventional locking device, and FIG. 3 is a schematic cross-sectional view of the conventional locking device.
In these drawings, the two locking devices 2 each include a locking hook body 21, a touch member 23, and a spring 25.
The locking hook body 21 has a substantially rectangular shape, and a rectangular groove 211 is formed in the central portion thereof.
Positioning bars 213 project from both sides of the locking hook body 21.
The spring 25 is fitted into the positioning bar 213.
A locking hook 215 is formed integrally with a part of the locking hook body 21.
The locking hook 215 can be locked in the corresponding locking groove 112 of the front cover 111.
The touch member 23 includes a locking surface 231 and a touch panel 233 facing the locking surface 231.
Four tenons 234 that are symmetrical to each other are provided on the locking surface 231.
The protruding directions of the four tenons 234 are all outward.
The touch panel 233 is a part that the user directly touches.

In addition, the front cover 111 of the screen case 11 is provided with through holes 112 at locations corresponding to the locking hooks 215 of the two locking devices 2.
The through hole 112 is a hole for penetrating the locking hook 215, and the locking hook 215 can be slid into the through hole 112.
Appropriate designs are also made at locations corresponding to the two locking devices 2 of the rear cover 113 of the screen case 11, and the limiting blocks 114 are provided at locations corresponding to the positioning bars 213 of the rear cover 113.
A through hole 116 is formed in the limited block 114.
The positioning bar 213 is inserted through the through hole 116.
A rectangular slide groove 118 is formed at a position of the rectangular groove 211 corresponding to the locking hook body 21 of the rear cover 113.
The length of the rectangular slide groove 118 is longer than the length of the rectangular groove 211.

Speaking of only one set of locking devices 2, in the conventional example, at the time of assembly, the spring 25 is first fitted into the positioning bars 213 on both sides of the locking hook body 21, and the two positioning bars 213 are respectively connected to the corresponding limiting blocks 114. It passes through the through hole 116.
The rectangular groove 211 of the locking hook body 21 is exactly aligned with the rectangular slide groove 118, and the touch member 23 is locked to the rectangular groove 211 through the rectangular slide groove 118 with four tenons 234 on the touch panel 233.
Thereby, the latching hook body 21 is positioned.
After the shaft of the positioning bar 213 reciprocates under the control of the touch member 23, the front cover 111 is made to correspond to the rear cover 113, the lids are aligned with each other, and the locking hook 215 of the locking hook body 21 passes through the front cover 111. It protrudes from the hole 112.
As a result, the width of the rectangular slide groove 118 is required as much as two tenon 234 passes.
When the user opens the lid of the notebook computer 1 and touches the touch panel 233 and moves the spring 25 in the compressing direction, the locking hook 215 of the locking hook body 21 and the locking groove 131 of the host case 13 are used. And the screen case 11 is pivoted relative to the host case to open the lid.
When the user covers the notebook computer 1, the screen case 11 is directly rotated to cover the host case 13, and the locking hooks 215 and the corresponding locking grooves 131 are slid. Thus, the locking hook can be easily locked in the locking groove 131.

However, since the conventional locking device 2 described above has a very large number of component parts, it is not only expensive to produce each part, but also has a large number of component parts. When there are many, there is a problem that it takes a lot of time to assemble.
In addition to this, since there is a need to make the notebook personal computer 1 smaller and thinner, the internal space of the notebook case 13 or the screen case 11 is reduced accordingly.
If the internal space of the screen case 11 is reduced in order to meet this user's needs, the front and rear covers 111 and 113 must be similarly manufactured in a thin size, so that the tenon 234 having two widths at the edge of the side surface of the rear cover 113. Therefore, there is a problem that it is more difficult to provide the rectangular slide groove 118 because a sufficient size sufficient to pass through cannot be secured.

Further, when the notebook computer is covered, the impact when an external force is applied acts abruptly as a shearing force, so that there is a problem that the locking hook is easily damaged.
The present invention has been completed as a result of many years of research and many experiments in order to solve the above problems.

  An object of the present invention is to provide a locking hook structure that can be applied to a screen case of a portable electronic device.
