[0002] With the development of technology, many electronic devices (such as notebook computers or handheld game consoles) are now quite popular and well-received products.

[0003] Generally, the housing of an electronic device can be composed of plastic and metal components. However, the metal component on the housing may be an independent block (such as a metal plate in a plastic substrate), so the static charge on this metal component may move to another metal component or electronic component inside the housing, resulting in secondary discharge. The secondary discharge will generate a strong electromagnetic field, which will in turn affect the normal operation of the electronic components inside the electronic device.

[0004] Therefore, how to design an electronic device that can avoid secondary discharge is a topic worthy of exploration and solution today. Summary of the Invention

[0005] In view of this, the present invention provides an electronic device to solve the above problems.

[0006] The present invention provides an electronic device, including a base, a cover, a metal member, and a protection device. The cover has a conductive material and is fixedly connected to the base. The metal member is fixedly disposed on the base. The protection device is disposed on the base and connected between the metal member and the cover. The cover and the base are arranged along a first axis, and when observed along the first axis, the protection device overlaps at least a part of the metal member.

[0007] According to some embodiments of the present invention, the protection device includes a first conductive member and a second conductive member. The second conductive member is disposed on the first conductive member. The first conductive member is configured to contact a part of the metal member, and the second conductive member is configured to contact a part of the cover.

[0009] According to some embodiments of the present invention, the metal component has at least one opening, the base is made of plastic material, and the part of the base corresponding to the at least one opening fixes the metal component to the base in a hot melting manner. The first section has at least one notch corresponding to the at least one opening. An insulating layer is provided on the surface of the metal component, and the metal component further has a contact portion configured to contact the first section of the first conductive component, wherein no insulating layer is provided on the contact portion.

[0010] According to some embodiments of the present invention, the metal component has a rectangular structure, and the first section contacts a first side of the rectangular structure.

[0011] According to some embodiments of the present invention, the metal component has a rectangular structure, and the first section and the second section respectively contact a first side and a second side of the rectangular structure.

[0012] According to some embodiments of the present invention, the metal component has a rectangular structure, the first conductive component has a frame-shaped structure corresponding to the rectangular structure, and the frame-shaped structure contacts the four sides of the rectangular structure.

[0013] According to some embodiments of the present invention, the length of the second section is 4 - 8 cm, and the distance between the second conductive component and the metal component along a third axis is 5 - 7 cm.

[0014] According to some embodiments of the present invention, the second section has a perforation, a positioning post is provided on the base, and when the protection device is fixed to the base, the positioning post passes through the perforation, wherein the positioning post is made of plastic material.

[0017] The protection device may include a first conductive member and a second conductive member. The second conductive member is fixedly disposed on the first conductive member. The first conductive member is configured to contact a part of the metal member, and the second conductive member is configured to contact a part of the cover.

For example, in the specification, it is mentioned that a first feature component is formed on a second feature component, which may include embodiments where the first feature component and the second feature component are in direct contact. Additionally, it may also include embodiments where there are other features between the first feature component and the second feature component. In other words, the first feature component and the second feature component are not in direct contact.

[0080] In addition, repeated reference numerals or labels may be used in different embodiments. These repetitions are only for simplicity and clarity in describing the present invention and do not represent a specific relationship between the different embodiments and / or structures being discussed. Further, forming, connecting to, and / or coupling to another feature component above another feature component in the present invention may include embodiments where the feature components are formed in direct contact, and may also include embodiments where additional feature components may be formed to insert between the above-mentioned feature components, such that the above-mentioned feature components may not be in direct contact.

And these terms related to joining and connection may also include cases where both structures are movable, or both structures are fixed.

[0084] Please refer to Figure 1 and Figure 2 , Figure 1 is an exploded schematic view of an electronic device 100 according to an embodiment of the present invention, and Figure 2 is a top view schematic of a partial structure of the electronic device 100 according to an embodiment of the present invention. The electronic device 100 is, for example, a notebook computer or a handheld game console, but is not limited thereto. In this embodiment, the electronic device 100 may include a base 102, a cover 104, a metal member 106, and a protection device 110.

[0085] The cover 104 and the base 102 are arranged along a first axis AX1, and the cover 104 is fixedly connected to the base 102 to form an accommodation space AS of the electronic device 100. The accommodation space AS is configured to accommodate a circuit board 108 and other electronic components, such as a touchpad, a keyboard (not shown in the figure), and so on. In this embodiment, the cover 104 may be made of a metal material, and the base 102 may be made of a plastic material, but is not limited thereto.

[0086] The metal member 106 is, for example, a metal sheet, fixedly disposed on the base 102 and having a plurality of openings 106P. The corresponding part of the base 102 to the openings 106P can fix the metal member 106 to the base 102 in a hot-melt manner. For example, a plurality of positioning posts 102P may be formed on the base 102, respectively passing through the plurality of openings 106P of the metal member 106, and the plastic positioning posts 102P can fix the metal member 106 to the base 102 by a manufacturing process such as hot melting or hot riveting. The connection manner between the metal member 106 and the base 102 is not limited thereto. For example, it can also be connected by means of glue bonding.

[0087] As Figure 2 shown, a plurality of ventilation holes 1021 are formed on the base 102, and the metal member 106 is disposed corresponding to these ventilation holes 1021. The metal member 106 may be formed with a plurality of through holes 106H corresponding to these ventilation holes 1021. The heat generated by the electronic device 100 can be dissipated to the external environment through the through holes 106H and the ventilation holes 1021 by the fan driving air.

[0088] To avoid damage to the electronic components on the circuit board 108 caused by secondary discharge of static charges generated on the metal component 106, the electronic device 100 may further include a protection device 110 disposed on the base 102 and connected between the metal component 106 and the cover 102. As Figure 2 shown, when viewed along the first axial direction AX1 (Z-axis), the protection device 110 overlaps at least a part of the metal component 106.

[0089] In this embodiment, the protection device 110 includes a first conductive member 112 and a second conductive member 114, and the second conductive member 114 is disposed on the first conductive member 112. For example, the first conductive member 112 is fixedly connected to the base 102 by glue, and the second conductive member 114 is fixedly connected to the first conductive member 112 by glue, but the connection method is not limited thereto. Furthermore, the first conductive member 112 is configured to contact a part of the metal component 106, and the second conductive member 114 is configured to contact a part of the cover 104.

[0090] As Figure 1 and Figure 2 shown, the first conductive member 112 has a first segment 1121 and a second segment 1122, and the second segment 1122 is connected to the first segment 1121. The first segment 1121 extends along a second axial direction AX2, and the second segment 1122 extends along a third axial direction AX3. Among them, the first axial direction AX1, the second axial direction AX2, and the third axial direction AX3 are perpendicular to each other.

[0091] In addition, as Figure 1 and Figure 2 shown, the metal component 106 has a rectangular structure, and the first segment 1121 contacts a first side 106S1 of this rectangular structure. Furthermore, the first segment 1121 may have at least one notch 1121C corresponding to at least one opening 106P. As Figure 2 shown, the first segment 1121 has four notches 1121C respectively corresponding to four openings 106P. When viewed along the first axial direction AX1, the first segment 1121 does not overlap the opening 106P.

[0092] Based on the design of the notch 1121C, the first conductive member 112 can be surely mounted on the base 102, and the positioning post 102P can assist the operator in positioning when mounting the first conductive member 112.

[0093] In this embodiment, an insulating layer 106I is provided on the surface of the metal member 106, and the metal member 106 further has a contact portion 106C configured to contact the first section 1121 of the first conductive member 112. It should be noted that no insulating layer 106I is provided on the contact portion 106C.

[0094] Therefore, the static electricity on the metal member 106 can be conducted to the first section 1121 through the contact portion 106C, and then through the second section 1122 and the second conductive member 114 to the ground terminal on the cover 104. That is, the protection device 110 can effectively conduct the static electricity to the ground terminal to protect the electronic components in the electronic device 100.

[0095] In addition, in this embodiment, the second section 1122 has a perforation 1122H, and a positioning post 102C is provided on the base 102. When the protection device 110 is fixed to the base 102, the positioning post 102C passes through the perforation 1122H to assist in positioning the protection device 110. The positioning post 102C can be made of plastic material, but is not limited thereto.

[0096] In this embodiment, the first conductive member 112 has flexibility, so the convenience of installation on the base 102 can be increased. In this embodiment, the first conductive member 112 can be made of a metal material, such as a conductive cloth, but is not limited thereto. The second conductive member 114 is, for example, a conductive gasket, but is not limited thereto.

[0097] In addition, it should be noted that as Figure 2 shown, when viewed along the first axis AX1, the protection device 110 does not overlap the main board 108. Based on such a configuration, it is possible to avoid static charges being transmitted to the main board 108 and causing damage to the electronic components.

[0098] Next, please refer to Figures 1 to 4 , Figure 3 which is a waveform diagram of the frequency and radiation intensity of an existing electronic device without the protection device 110 added, and Figure 4 which is a waveform diagram of the frequency and radiation intensity of the electronic device 100 with the protection device 110 added according to an embodiment of the present invention. In this embodiment, adding the protection device 110 can reduce the electromagnetic interference (EMI) of the electronic device 100.

[0099] As Figure 3 shown, before the protection device 110 is added, obvious noise (such as noise NS1 to noise NS6) is generated in the existing electronic device between 400 Hz and 500 Hz, which affects the normal operation of the electronic components or chips in the existing electronic device.

[0100] As Figure 4 shown, after adding the protection device 110, the noise of the electronic device 100 between 400 Hz and 500 Hz is significantly reduced, so that the normal operation of the electronic components or chips in the electronic device 100 can be ensured.

[0101] It should be noted that, as Figure 2 shown, the length LT21 of the second section 1122 of the first conductive member 112 can be 4 - 8 cm, and the distance LT31 between the second conductive member 114 and the metal member 106 along the third axis AX3 can be 5 - 7 cm. The distance LT31 can be one-tenth, one-fifth or one-quarter of the wavelength corresponding to 500 Hz. Based on such a length design, not only can the problem of static electricity generation be avoided, but also electromagnetic interference can be effectively reduced.

[0102] Next, please refer to Figures 5 to 6 , Figure 5 which is a schematic diagram of a protection device 110A according to another embodiment of the present invention, and Figure 6 which is a schematic diagram of a protection device 110B according to another embodiment of the present invention. Among them, the size of the protection device can be adjusted according to actual needs. For example, the protection device 110A corresponds to a 14-inch notebook computer, and the protection device 110 corresponds to a 15-inch notebook computer.

[0103] Specifically, as Figure 2 and Figure 5 shown, the length LT12 of the first section 1121 of the first conductive member 112A of the protection device 110A is less than the length LT11 of the first section 1121 of the protection device 110, and the length LT22 of the second section 1122 of the first conductive member 112A of the protection device 110A is also less than the length LT21 of the second section 1122 of the protection device 110.

[0104] Similarly, as Figure 2 and Figure 6 shown, the length LT13 of the first section 1121 of the first conductive member 112B of the protection device 110B is less than the length LT11 of the first section 1121 of the protection device 110, and the length LT23 of the second section 1122 of the first conductive member 112B of the protection device 110B is also less than the length LT21 of the second section 1122 of the protection device 110.

[0105] Furthermore, the length LT23 of the second segment 1122 of the protection device 110B is also less than the length LT22 of the second segment 1122 of the protection device 110A. Furthermore, the size of the second conductive member 114 of the protection device 110B is larger than the size of the second conductive member 114 of the protection device 110A, thus increasing the contact area, and further enabling more effective conduction of static electricity to the base 102.

[0106] It should be noted that since the first conductive member 112 is flexible, the protection device 110 can also be applied to a 14-inch notebook computer. As long as the second segment 1122 is folded to reduce its length, it can be installed on a 14-inch notebook computer. That is, electronic devices of different sizes can adopt a protection device of a single size, thus further reducing the production cost.

[0107] Next, please refer to Figure 7 , Figure 7 is a top view schematic diagram of a protection device 110C and a metal member 106 according to another embodiment of the present invention. In this embodiment, the metal member 106 has a rectangular structure, and the first segment 1121 and the second segment 1122 of the first conductive member 112C respectively contact a first side 106S1 and a second side 106S2 of the rectangular structure.

[0108] Similarly, a first contact portion 106C1 and a second contact portion 106C2 are respectively provided on the first side 106S1 and the second side 106S2, and no insulating layer is provided on the first contact portion 106C1 and the second contact portion 106C2. The first contact portion 106C1 and the second contact portion 106C2 are configured to respectively contact the first segment 1121 and the second segment 1122. Based on such a structural configuration, the contact area between the protection device 110C and the metal member 106 can be increased, and thus the efficiency of removing static charges can be increased.

[0109] Please refer to Figure 8 , Figure 8 is a top view schematic diagram of a protection device 110D and a metal member 106 according to another embodiment of the present invention. In this embodiment, the metal member 106 has a rectangular structure, and the first segment 1121 and the second segment 1122 of the first conductive member 112D can form a frame structure corresponding to the rectangular structure, and the frame structure contacts the four sides of the rectangular structure.

[0110] As shown in Figure 8As shown, the first section 1121 contacts the first contact portion 106C1, the third contact portion 106C3, and the fourth contact portion 106C4 on the first side 106S1, the third side 106S3, and the fourth side 106S4, while the second section 1122 contacts the second contact portion 106C2 on the second side 106S2.

[0111] Similarly, no insulating layer is provided on the first contact portion 106C1, the second contact portion 106C2, the third contact portion 106C3, and the fourth contact portion 106C4. Based on such a structural configuration, the contact area between the protection device 110D and the metal component 106 can be further increased, thereby increasing the efficiency of removing static charges.

[0112] In summary, the present invention provides an electronic device, including a base, a cover, a metal component, and a protection device. The cover has a conductive material and is fixedly connected to the base. The metal component is fixedly disposed on the base. The protection device is disposed on the base and connected between the metal component and the cover. The cover and the base are arranged along a first axis, and when viewed along the first axis, the protection device overlaps at least a part of the metal component.

[0113] The protection device may include a first conductive member and a second conductive member. The second conductive member is fixedly disposed on the first conductive member. The first conductive member is configured to contact a part of the metal component, and the second conductive member is configured to contact a part of the cover. Based on such a configuration, when static electricity is generated on the metal component, the static electricity can be conducted to the first section of the first conductive member through the contact portion of the metal component, and then sequentially pass through the second section of the first conductive member and the second conductive member and be conducted to the ground terminal on the cover. Therefore, the protection device can effectively conduct the static electricity to the ground terminal to protect the electronic components in the electronic device from being damaged by static electricity.

[0114] In some embodiments, the first conductive member has an L-shaped structure, but is not limited thereto. In other embodiments, the first conductive member may have a frame-shaped structure. Additionally, the first conductive member has flexibility, thus increasing the convenience of installation on the base, and since it can be bent or folded, protection devices of a single size can be used for electronic devices of different sizes, thereby further reducing production costs.
