Description

Electronic devices

The present invention relates to an electrostatic protection structure for an electronic device, and in particular to an electrostatic protection structure suitable for an internal camera module of the electronic device.

Electronic devices, such as the camera element inside a laptop computer, are easily damaged by electrostatic discharge (ESD). In the prior art, electrostatic protection measures are generally taken for the lens of the camera element. However, due to the design trend of laptop computers with a high screen-to-body ratio (i.e., the ratio of the area of the display screen to the area of the surface where the display screen is located) and the trend towards a thin and light design, the camera element is quite close to the edge of the housing of the electronic device, and the pins of the connector of the camera element are still easily damaged by external static electricity.

Therefore, how to prevent the connector of the imaging element from being damaged by external static electricity through improvement of the structural design to overcome the above-mentioned defects has become one of the important issues to be solved in this field.

The present invention mainly provides an electronic device which can solve the problem in the prior art that the connector pins of the imaging element are easily damaged by static electricity through an internal static electricity protection structure.

In order to solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide an electronic device, which includes a camera module, a first shell, a second shell and an electrostatic protection structure. The electrostatic protection structure includes a first conductive part, a second conductive part and an extension structure. The camera module has a connector. The first shell has a metal part and a non-metal part connected to the inner surface of the metal part, and the non-metal part has an opening. The first conductive part is arranged in the opening and is electrically connected to the metal part. The second conductive part is arranged on a side of the non-metal part away from the metal part and is electrically connected to the first conductive part. The camera module is arranged on a side of the second conductive part away from the non-metal part. The second shell is joined to the first shell. The extension structure is arranged between the first shell and the second shell and contacts the second conductive member. The extension structure is closer to the edge of the first shell than the connector.

One of the beneficial effects of the present invention is that the electronic device provided by the present invention can, through the technical solutions of "the extension structure is arranged between the first shell and the second shell and contacts the second conductive member" and "the extension structure is closer to the edge of the first shell than the connector", enable external static electricity to be guided to the ground through the configuration of the extension structure and the second conductive member.

To further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings provided are only used for reference and description and are not used to limit the present invention.

[First embodiment]

Referring to FIG. 1 and FIG. 2 , FIG. 1 is a three-dimensional schematic diagram of the electronic device of the present invention, and FIG. 2 is a schematic diagram of the electronic device of the first embodiment of the present invention, and FIG. 2 is a schematic diagram of the II-II cross-section of FIG. 1 . The present invention provides an electronic device. For example, the electronic device D is a laptop computer, but the present invention is not limited to the type of the electronic device D. The electronic device D includes a first shell 1, a second shell 4, a camera module B, and an electrostatic protection structure M. The camera module B is disposed in the electronic device D and is located above the screen S. The first shell 1 is joined to the second shell 4 to form an inner cavity C. In the embodiment of the present invention, the first shell 1 is the back cover (commonly known as part A) of the laptop computer. The second housing 2 is the front frame of the laptop (commonly known as B part), which is where the display screen is located. The first housing 1 has a metal part 11 and a non-metal part 12 connected to the inner surface of the metal part 11. For example, the metal part 11 is made of aluminum, and the non-metal part 12 is made of plastic.

The electrostatic protection structure M includes a first conductive member 2, a second conductive member 3, and an extension structure 5. The first conductive member 2, the second conductive member 3, the extension structure 5, and the camera module B are located in the inner cavity C mentioned above.

Referring to FIG. 2 and FIG. 3 , FIG. 3 is a partial schematic diagram of the first shell of the electronic device of the present invention. The non-metallic part 12 has an opening 120, and the metal conductive area 110 on the inner surface of the metal part 11 is exposed in the opening 120. The first conductive member 2 is disposed in the opening 120, and the first conductive member 2 is electrically connected to the metal part 11. In addition to the original camera (not shown), the camera module B also includes a connector B1 and a circuit board B2, the connector B1 is electrically connected to the circuit board B2, and the circuit board B2 is disposed on the second conductive member 3. The second conductive member 3 is disposed on a side of the non-metallic part 12 away from the metal part 11, and the second conductive member 3 is electrically connected to the first conductive member 2. The camera module B is disposed on a side of the second conductive element 3 away from the non-metallic portion 12. The camera module B is electrically connected to the metal portion 11 through the second conductive element 3 and the first conductive element 2 to achieve a grounding effect.

The inner surface area of the metal part 11 in the opening 120 is the metal conductive area 110. The metal conductive area 110 can be laser engraved to form a conductive pattern in the area, but the present invention is not limited thereto. In addition, for example, the first conductive member 2 can include a metal pad 21 and a conductive glue 22. The metal pad 12 can be fixed in the opening 120 through the conductive glue 22 and electrically connected to the metal conductive area 110. The second conductive member 3 can be a conductive cloth, which is soft and suitable for folding into various shapes.

The extension structure 5 is disposed between the first housing 1 and the second housing 4. Specifically, the extension structure 5 is in contact with the second conductive member 3. As shown in FIG. 2 , the extension structure 5 is closer to the edge E of the first housing 1 than the connector B1. Therefore, the present invention forms an electrostatic grounding path by configuring the extension structure 5 and the second conductive member 3. Since the extension structure 5 is closer to the edge E of the first housing 1, when static electricity passes through the first housing 1 and the second housing 4 from the external environment and enters the interior of the electronic device D, the static electricity will be guided by the extension structure 5 and grounded through the electrostatic grounding path, thereby avoiding direct damage to the pin B11 of the connector B1.

As shown in FIG. 2 , in the first embodiment, the second conductive member 3 contacts the extension structure 5 and extends toward the edge E of the first housing 1, so that the contact area between the extension structure 5 and the second conductive member 3 is maximized. Specifically, the first housing 1 includes a first hook member 121, and the second housing 4 includes a second hook member 41. The first hook member 121 and the second hook member 41 can be combined, so that the first housing 1 and the second housing 4 are assembled into one component. In this embodiment, the extension structure 5 extends from the second hook member 41 toward the first housing 1 until it contacts the second conductive member 3. Furthermore, the extension structure 5 can be a part of the second hook member 41, and the extension structure 5 extends downward from the second hook member 41 and contacts the second conductive member 3. The structural design of the extension structure 5 and the second conductive member 3 can achieve the effect of guiding external static electricity to the ground.

[Second embodiment]

Referring to FIG. 4, FIG. 5 and FIG. 6, FIG. 4 is a schematic diagram of an electronic device of the second embodiment of the present invention, FIG. 5 is a three-dimensional schematic diagram of the electrostatic protection structure of the electronic device of FIG. 4, and FIG. 6 is a schematic diagram of the back of the extension structure of the electrostatic protection structure of FIG. 5. In the second embodiment, the extension structure 5 is a partition wall. The extension structure 5 extends from the non-metallic part 12 toward the second housing 4 and is located between the first hook 121 and the connector B11. The distance L1 between the top of the connector B1 and the surface of the non-metallic part 12 is less than the height L2 of the extension structure 5.

The extension structure 5 includes a first surface 51 and a second surface 52 opposite to each other, the first surface 51 faces the connector B1, and the second surface 52 faces the first hook member 121. The second conductive member 3 extends toward the first housing 1 to cover the first surface 51 and the second surface 52, and is attached to the surface of the extension structure 5. The structural design of the extension structure 5 and the second conductive member 3 achieves the effect of guiding external static electricity to the ground.

Specifically, the portion of the second conductive member 3 extending to the first surface 51 partially covers the first surface 51, and the portion of the second conductive member 3 extending to the second surface 52 completely covers the second surface 52. As shown in FIG5 , the portion of the second conductive member 3 extending to the first surface 51 includes a first conductive portion 31 and a second conductive portion 32. The first conductive portion 31 and the second conductive portion 32 are respectively located on both sides of the first surface, and there is a fixed distance H between the first conductive portion 31 and the second conductive portion 32. The width of the projection area of the connector B1 (including the pin B11) vertically projected onto the first surface 51 is equal to or less than the fixed distance H. In other words, the portion of the second conductive member 3 extending to the first surface 51 has a conductive member portion in the middle hollowed out, leaving only conductive member portions on both sides (i.e., the first conductive portion 31 and the second conductive portion 32).

When the second conductive member 3 extends to the first surface 51, the middle portion of the second conductive member 3 is closest to the connector B1 and its pin B11. Therefore, the present invention prevents the portion of the second conductive member 3 extending to the first surface 51 from being too close to the connector B1 and its pin B11 by hollowing out the middle portion of the second conductive member 3, further preventing static electricity from damaging the pin B11 when flowing through the second conductive member.

[Beneficial Effects of Embodiments]

One of the beneficial effects of the present invention is that the electronic device D provided by the present invention can, through the technical solutions of "the extension structure 5 is arranged between the first shell 1 and the second shell 4 of the electronic device D and contacts the second conductive member 3" and "the extension structure 5 is closer to the edge of the first shell 1 than the connector B1", enable external static electricity to be guided to the ground through the configuration of the extension structure 5 and the second conductive member 3.

Furthermore, the extension structure 5 can be connected to the second hook member 41, that is, the extension structure 5 can be a part of the second hook member 41. The second conductive member 3 extends toward the edge E of the first housing 1. Therefore, the extension structure 5 can extend downward from the second hook member 41 to contact the second conductive member 3, thereby achieving the effect of guiding external static electricity to the ground. Furthermore, the extension structure 5 is a partition wall. The extension structure 5 is disposed in the non-metallic portion 12 and is located between the first hook member 121 and the connector B11.

In another embodiment, the second conductive member 3 extends from the first surface 51 to the second surface 52 and is attached to the surface of the extension structure 5. The structural design of the extension structure 5 and the second conductive member 3 can achieve the effect of guiding external static electricity to the ground.
