Detailed ways

A first embodiment according to the present invention is a snap-fit device. The locking device can be applied to any device that needs to lock its upper cover and base, such as notebook computers, foldable mobile phones or electronic game devices. Please refer to FIG. 1A and FIG. 1B . FIG. 1A and FIG. 1B are schematic diagrams illustrating the engaging device. As shown in FIG. 1A and FIG. 1B , the engaging device 10 is located on an upper cover of a device, and includes an engaging element 12 and a second magnetic component 14 . The locking element 12 is movably disposed on the upper cover, and includes a first magnetic component 16 and a locking component 18 . The second magnetic component 14 is also disposed on the upper cover and corresponds to the first magnetic component 16 . As shown in FIG. 1A and FIG. 1B , the engaging element has a first position P1 and a second position P2 on the upper cover. When the engaging element 12 is operated to move from the first position P1 to the second position P2, a magnetic force (repulsive force) generated between the second magnetic member 14 and the first magnetic member 16 assists the engaging element 12 to return The first position P1.

In practical applications, the engaging device 10 may further include a limiting member (not shown in FIGS. 1A and 1B ). The restraining member is usually disposed on the base of the device. The engaging member 18 can cooperate with the restricting member. When the engaging element 12 is located at the first position P1, the engaging member 18 can cooperate with the restricting member to form a locking engagement. In contrast, when the engaging member 18 is located at the second position P2, the locking engagement will be released.

For example, the restricting member and the engaging member 18 of the engaging device 10 can be a slot and a tenon respectively, and the tenon can cooperate with the slot. After the upper cover of the device is closed relative to the base, the tenon is at the first position P1, and the tenon can form a locking engagement with the slot. The locking engagement means that the upper cover and the base form a locked state. On the other hand, when the tenon is at the second position P2, the locking engagement formed by the tenon and the slot will be released. That is to say, when the tenon is at the second position P2, the upper cover and the base can be separated.

In addition, the first magnetic component 16 and the second magnetic component 14 can be respectively a magnet, but not limited thereto. According to the invention, the ends of the two magnets facing each other must have the same polarity. For example, suppose the first magnetic component is a first magnet, and the second magnetic component is a second magnet. As shown in FIG. 1A and FIG. 1B , if the S pole of the first magnet faces the second magnet, then the second magnet must also face the first magnet with its S pole. Conversely, if the N pole of the first magnet faces the second magnet, the second magnet must also face the first magnet with its N pole. In this way, when the first magnet approaches the second magnet, a repulsive magnetic force will be generated between the first magnet and the second magnet. As mentioned above, when the engaging element 12 is operated to move from the first position to the second position, the repulsive magnetic force generated between the first magnet and the second magnet can assist the engaging member 18 Return to the first position.

A second specific embodiment according to the present invention is an electronic device. The electronic device can be any device that needs to lock its upper cover and base, such as a notebook computer, a foldable mobile phone, or an electronic game. Please refer to FIG. 2 , which is an appearance view of the electronic device. As shown in FIG. 2 , the electronic device 22 includes a base 24 , an upper cover 26 and an engaging device 10 . The upper cover 26 is pivotally connected to the base 24 . The engaging device 10 is disposed on the upper cover 26 and includes an engaging element 12 and a second magnetic component 14 . The locking element 12 has a first magnetic component 16 and a locking component 18 . The second magnetic member 14 corresponds to the first magnetic member 16 . The engaging element 12 has a first position and a second position on the upper cover 26. When the engaging element 12 is operated to move from the first position to the second position, the second magnetic member 14 and the first magnetic member A magnetic force generated between 16 assists the engaging member 18 to return to the first position.

In practical applications, the electronic device 22 may further include a limiting member 20 . The restricting member 20 is provided on the base 24 . The snapping member 18 can cooperate with the restricting member 20 . When the engaging member 18 is in the first position, the engaging member 18 can cooperate with the restricting member 20 to form a locking engagement. On the other hand, when the engaging member 18 is in the second position, the locking engagement is released.

In the embodiment shown in FIG. 2 , the electronic device 22 is a notebook computer, and the limiting member 20 and the engaging member 18 are respectively a slot and a tenon. The tenon can be matched with the slot. When the tenon is at the first position, if the top cover of the notebook computer is closed relative to the base 24 , the tenon can form a locking engagement with the slot. The locking engagement means that the upper cover and the base form a locked state. On the other hand, when the tenon is at the second position, the locking engagement formed by the tenon and the slot will be released.

In addition, the first magnetic component 16 and the second magnetic component 14 can be respectively a magnet, but not limited thereto. And according to the present invention, the polarities of the opposite ends of the two magnets must be the same. For example, suppose the first magnetic component is a first magnet, and the second magnetic component is a second magnet. As shown in FIG. 2 , if the S pole of the first magnet faces the second magnet, the second magnet must also face the first magnet with its S pole, and vice versa. In this way, when the engaging element 12 is operated to move from the first position to the second position, the repulsive magnetic force generated between the first magnet and the second magnet can assist the engaging element 12 to return to the second position. first position.

In practical applications, the electronic device 22 may further include a reed switch 28, such as a Hall sensor, as shown in FIG. 2 . An open/short circuit state of the reed switch 28 is related to the magnitude of the magnetic field detected by the reed switch 28 . When the angle between the upper cover 26 and the base 24 is greater than a threshold angle, for example, when the user opens the upper cover 26, since the magnetic reed switch 28 gradually moves away from the first magnetic member 16 and the second magnetic member 14, the detected magnetic field The size is relatively gradually reduced. When the detected magnetic field is smaller than a preset value, the magnetic reed switch 28 will send a signal to notify the electronic device 22, and the electronic device 22 activates some components of the electronic device according to the signal, such as the screen , hard disk, etc.; when the angle was less than the threshold angle, the reed switch 28 would turn off the power supply. On the contrary, when the angle between the upper cover and the base is less than a threshold angle, for example, when the user closes the upper cover 26, since the magnetic reed switch 28 gradually approaches the first magnetic member 16 and the second magnetic member 14, the detected The magnitude of the magnetic field increases relatively gradually. When the detected magnetic field magnitude is greater than a preset value, the reed switch 28 will send a signal to notify the electronic device 22, and the electronic device 22 will close some components of the electronic device 22 according to the signal. Such as screen, hard disk, etc.

Compared with the background technology, according to the locking device of the present invention and the electronic equipment using the locking device, not only the use of springs in the background technology can be omitted to avoid the phenomenon of being unable to lock due to elastic fatigue, but also the locking The magnet of the device can also provide the electronic device with a reed induction to control its power switch to save power.
