Any related art and related art can easily understand the related purposes and advantages of the present invention. The following examples are intended to describe the present invention in further detail, but do not limit the scope of the present invention in any way.

1 and FIG. 2, FIG. 1 is a perspective view of an electronic device according to an embodiment of the present invention, and FIG. 2 is a side view of the electronic device of FIG.

The electronic device 1 includes a first body 10, a second body 20 and an electronic component 40. The first body 10 and the second body 20 are connected to each other, and the electronic component 40 may be disposed on the first body 10 or the second body 20. In the embodiment, the electronic component 40 is disposed on the first body 10. For example, the electronic device 1 can be a notebook computer, and the electronic component 40 is a screen. In other embodiments, the first body 10 of the electronic device 1 is a tablet computer, and the second body 20 is a base or a Enter the platform. Furthermore, in this embodiment and some other embodiments, the electronic device 1 further includes a pivoting member 30 for pivotally connecting the first body 10 and the second body 20 such that the first body 10 and the second body The 20 is pivotable relative to the pivot member 30 to have a plurality of positions. The material of the pivoting member 30 may be metal to enhance the fixing effect.

The first body 10 includes a first housing 11 and a plurality of magnetic members 12. The magnetic member 12 is disposed in the first housing 11. The first housing 11 has a first side 111 and a third side 113 opposite to each other. For example, the magnetic member 12 is a permanent magnet. Moreover, the number of magnetic members 12 in the drawings is not intended to limit the present invention, and can be arbitrarily adjusted according to design requirements.

The second body 20 includes a second housing 21, a plurality of magnetic sensors 22, a plurality of magnetically conductive members 23, and a switch control element 24. The second housing 21 has a second side 212 and a fourth side 214 opposite to each other, and the second side 212 of the second housing 21 is coupled to the first side 111 of the first housing 11 in a relatively movable manner. In the present embodiment, the first distance D1 between the magnetic member 12 and the pivoting member 30 is substantially equal to the second distance D2 between the magnetic sensor 22 and the pivoting member 30. As such, the spacing between the first side 111 of the first housing 11 and the second side 212 of the second housing 21 remains fixed, while the third side 113 of the first housing 11 and the fourth side of the second housing 21 The distance of the side 214 varies with the pivoting between the first body 10 and the second body 20.

Furthermore, the magnetic sensor 22, the magnetic conductive member 23 and the switch control element 24 are all disposed in the second housing 21. The magnetic sensor 22 is disposed on the magnetic conductive member 23, and the switch control member 24 is electrically connected to the magnetic sensors 22. The magnetic conductive member 23 is a magnetic conductive material, and the magnetic conductive member 23 is used to expand and guide the magnetic field of the magnetic member 12. The magnetic sensor 22 is used to detect the magnetic flux of the magnetic member 12. In the present embodiment, the magnetic sensor 22 is a Hall sensor, and the material of the magnetic conductive member 23 may be a magnetic conductive material, and the magnetic conductive material is not magnetized by the magnetic member 12. The magnetically permeable member 23 can be, for example but not limited to, a ferrite sheet or a silicon steel sheet. The switch control element 24 can be an embedded controller. The Hall sensor transmits a first Hall voltage to the switch control element 24 according to the magnetic field of the detected side being greater than a first value, so that the switch control element 24 turns off the electronic component 40. Conversely, if the Hall sensor can be based on the detected magnetic field being less than or equal to the first value, the Hall sensor can output a second Hall voltage to the switch control element 24 to cause the switch control element 24 to turn on the electronic component. 40. In addition, since the magnetic sensor 22 is disposed away from the pivoting member 30, the magnetic flux detected by the magnetic sensor 22 via the pivoting member 30 is always smaller than the first value. Therefore, the magnetic field from the magnetic member 12 guided by the pivoting member 30 does not affect the detection side of the magnetic sensor 22, so the accuracy of the detection by the magnetic sensor 22 can be improved.

However, in other embodiments, if the magnetic field detected by the magnetic sensor 22 is greater than a first value, a first Hall voltage is output to the switch control element 24 to cause the switch control element 24 to turn off the electronic component 40. If the magnetic sensor 22 can be less than or equal to a second value according to the detected magnetic field, the magnetic sensor 22 can output a second Hall voltage to the switch control element 24, so that the switch control element 24 turns off the electronic component. 40. That is, the first value can be equal to the second value, or the first value can be greater than the second value. For example, the first value may be 15 Gauss, and the second value may be 5 Gauss. When the magnetic flux on the side of the magnetic sensor 22 is increased to 15 Gauss, the electronic component 40 can be turned off; When the magnetic flux on the side of the detected side is reduced to 5 gauss, the electronic component 40 can be turned on. In detail, the Hall sensor will have a hysteresis, and the Hall sensor will change the Hall voltage of the output and the value of the detected magnetic flux will be different.

In the present invention, the magnetic sensor 22 is disposed on the magnetic conductive member 23 to directly connect the magnetic sensor 22 to the magnetic conductive member 23, or the magnetic sensing device 22 is disposed adjacent to the magnetic conductive member 23. It is not directly connected to the magnetic conductive member 23. Thus, the magnetic conductive member 23 can effectively guide and expand the magnetic field to the magnetic sensor 22. In addition, the number of the magnetic sensor 22 and the magnetic conductive member 23 are not used to limit the present invention, and can be arbitrarily adjusted according to design requirements.

In addition, in the embodiment and some other embodiments, the electronic device 1 further includes an input module 50. The input module 50 is disposed in the second housing 21. For example, the input module 50 is a keyboard. However, it is not intended to limit the present invention. In other embodiments, the input module 50 can be a touchpad.

The following describes the operation mode of the present case. First, referring to FIG. 2, at this time, the magnetic sensor 22 is separated from the magnetic member 12 by a first distance L1, and the electronic component 40 is kept open.

Please refer to FIG. 3 , which is a side view of the second body of the electronic device in a position according to an embodiment of the invention. Next, the first body 10 is pushed to rotate toward the second body 20. At this time, the first body 10 has a first position relative to the second body 20, and the magnetic sensor 22 is spaced apart from the magnetic member 12 by a second distance L2. At the same time, the magnetic sensor 22 detects that the magnetic flux of the magnetic member 12 is less than or equal to the first value, so that the electronic component 40 remains open.

Please refer to FIG. 4 , which is a side view of the second body of the electronic device in another position according to an embodiment of the invention. Then, the first body 10 is continuously pushed to rotate toward the second body 20. At this time, the first body 10 has a second position relative to the second body 20, and the magnetic sensor 22 is spaced apart from the magnetic member 12 by a second distance. The second spacing L2 between the magnetic sensor 22 and the magnetic member 12 in the first position is greater than the third spacing L3 between the magnetic sensor 22 and the magnetic member 12 in the second position. At this time, the magnetic sensor 22 detects that the magnetic flux of the magnetic member 12 is greater than the first value, so the switch control element 24 switches the switch of the electronic component 40 to turn off the electronic component 40. Conversely, if the electronic component 40 is to be turned on, the first body 10 needs to be pivoted away from the fourth side 214 of the second housing 21 of the second body 20 until the magnetic sensor 22 detects the magnetic member 12. When the magnetic flux is less than or equal to a specific value, the electronic component 40 can be automatically turned on.

The influence of the magnetically permeable member 23 on the detection effect of the magnetic sensor 22 will be described below. First, set up a control group first. That is, the magnetic conductive member 23 (ferrite plate member) is not provided, and a magnetic member 12 (permanent magnet) is sequentially placed at 1, 2, 3, and 4 cm apart from a magnetic sensor, and magnetic sensing is performed. The measured magnetic flux is 70, 25, 3, 2 Gauss. Next, an experimental group is set, the magnetic conductive member 23 is placed on the magnetic sensor, and then a magnetic member 12 is sequentially placed at 1, 2, 3, and 4 cm apart from the magnetic sensor, and the magnetic sensor can be The measured magnetic fluxes were 143, 78, 52, and 21 Gauss. As a result, the magnetically permeable member 23 does have an effect of expanding and guiding the magnetic field. Therefore, the electronic device 1 of the present invention can set a small power consumption and a small magnetic sensor to achieve the same detection effect. As such, the magnetic sensor and magnetic member 12 can be placed away from the pivot while consuming the same amount of power to avoid being disturbed by the magnetic permeability of the pivot. In addition, the designer can configure the magnetic conductive member 23 and the magnetic sensor according to the actual situation to achieve the light and short effect of the electronic device 1.

It should be noted that the arrangement of the pivoting member 30 is not intended to limit the present invention. In other embodiments, the setting of the pivoting member 30 can also be omitted, so that the magnetic sensor 22 can be achieved. The magnetic field of the magnetic member 12 is expanded by the magnetic conductive member 23 to switch the switch of the electronic component 40.

According to the electronic device disclosed above, by arranging the magnetic conductive member on the magnetic sensor, the magnetic field of the magnetic conductive member can be enlarged. In this way, the magnetic sensor can detect the magnetic field of the magnetic member at a long distance. Therefore, the magnetic sensor and the magnetic member can be disposed at a preferred position to avoid interference of other components (such as a pivotal member), thereby improving the accuracy of detection. In addition, the magnetic sensor can require less power and maintain the detection function, thereby achieving power saving.
