Hereinafter, on the basis of the above-described configuration, the operating state of the locking unit 140 of the portable terminal 100 according to the present invention will be described.

7 to 9 are cross-sectional views of the portable terminal 100 according to the present invention, which is a view for explaining an operating state of the locking unit 140.

First, an operation in which the battery cover 130 is unlocked from the terminal body 110 will be described. 7 illustrates a state in which the battery cover 130 is locked to the terminal body 110. In the state of FIG. 7, the locking hook 133 of the battery cover 130 is connected to the locking portion 144 of the locking member 141. It is stuck and fixed.

The spring 146 mounted on the locking member 141 is in a state of applying an elastic force to the locking member 141 in the direction in which the locking hook 133 is engaged, and the elastic member 149 of the rear case 112 is in a compressed state. The elastic force is applied to the battery cover 130 in the separation direction of the battery cover 130.

When the user pushes the button part 143 of the locking member 141 in the state of FIG. 7, the locking member 141 moves in the pressing direction as shown in FIG. 8. Accordingly, the locking portion 144 of the locking member 141 is moved relative to the locking hook 133 of the battery cover 130 so that the locking of the locking hook 133 is released, and the spring 146 is a user. It is compressed by the pressing force.

In addition, as the locking member 141 moves, the pushing member 135 disposed in the locking member 141 also moves toward the locking hook 133, and the pushing member 135 is in contact with the locking hook 133. The locking hook 133 is pushed in the separation direction of the battery cover 130.

At least one of the pushing member 135 and the locking hook 133 may have an inclined surface, and the battery cover 130 moves in a direction perpendicular to the pushing direction of the pushing member 135.

Meanwhile, the elastic restoring force of the elastic member 149 disposed on the rear case 112 acts on the battery cover 130. That is, the pushing member 135 pushes the battery cover 130 primarily in the separation direction, and the elastic member 149 pushes the battery cover 130 second in the separation direction.

Accordingly, the battery cover 130 moves in the separation direction as shown in FIG. 9, and rotates around the locking protrusion 132 (see FIG. 3) of the battery cover 130.

The locking member 141 is returned to its original position by the elastic restoring force of the spring 146 as shown in FIG. 9, and the locking member 141 has a stopper 148 (see FIG. 6) on the rear surface of the mounting groove 102. The locking will limit its movement.

Next, the operation of locking the battery cover 130 to the terminal body 110 will be described. The user moves the battery cover 130 toward the terminal body 110 as shown in FIG. 9. Accordingly, the locking hook 133 of the battery cover 130 enters the locking member 141 to be inserted into the insertion groove 145.

Here, the locking hook 133 is in contact with the inclined surface of the locking portion 144 formed in the locking member 141, so that the locking hook 133 is moved to the lower side of the terminal body (110). When the locking hook 133 passes through the inclined surface of the locking portion 144, the locking member 141 is moved upward by the elastic restoring force of the spring 146, and thus the locking hook 133 is locked. The battery cover 130 is locked to the terminal body 110 by being locked to the terminal body 110.

In the above description, the locking unit 140 has been described based on the configuration of locking or unlocking the battery cover 130 covering the battery 125 to the terminal body 110. However, the locking unit 140 is not limited thereto. The cover covering various mounting parts mounted on the terminal body 100 may be used to lock or unlock the terminal body 110.

In addition, while the bar type has been described based on the portable terminal, the above-described configuration may be applied to various types of portable terminals such as a folder type, a slide type, a swing type, and a swivel type.
