[0027] Static electricity is a static charge that forms when it accumulates on an object. Static electricity can be categorized as positive or negative. When an object with static electricity contacts an object with zero potential or a potential difference, charge transfer occurs, resulting in spark discharges. During the use of electronic devices, static electricity can strike the electronic components within them, causing irreversible hardware damage.

[0028] The present disclosure provides an electronic device. Figure 1is a schematic diagram of a partial cross-sectional structure of an electronic device in an exemplary embodiment of the present disclosure, such as Figure 1 As shown, the electronic device includes a housing 11 and a functional component 12. The housing 11 includes a first structural portion 111. The first structural portion 111 forms a functional opening 112 that connects the inside and outside of the electronic device. The functional component 12 is assembled in the functional opening 112. The functional component 12 includes a main structure 121 and a sealing structure 122 disposed on the main structure 121. The sealing structure 122 is sealed with the first structural portion 111 to separate the first structural portion 111 into a first portion 1111 close to the outside of the electronic device and a second portion 1112 away from the outside of the electronic device. Figure 1 The middle dashed line may represent the longitudinal position where the sealing structure 122 forms a seal with the first structural portion 111. The first structural portion 111 on the right side of the dashed line may be the first portion 1111, and the first structural portion 111 on the left side of the dashed line may be the second portion 1112. The first portion 1111 includes a waterproof outer layer 1111b, and the second portion 1112 includes a metal segment 1112a that is electrically conductively connected to the metal ground of the electronic device.

[0029] Since the first structural portion 111 of the electronic device housing 11 encloses the functional opening 112, the functional component 12 can achieve a seal between the main structure 121 and the first structural portion 111 through the sealing structure 122 when assembled in the functional opening 112, thereby separating the first structural portion 111 into a first portion 1111 and a second portion 1112. The metal section 1112a in the second portion 1112 that is conductively connected to the metal ground can guide static discharge inside the sealing structure 122. The first portion 1111 includes a waterproof outer layer 1111b, thereby avoiding chronic corrosion and penetration of metal components and the connection between the metal components and the first portion 1111, thereby achieving electrostatic protection while ensuring the waterproof effect of the entire device. The above structural improvement is simple and reduces the cost of electrostatic protection.

[0030] It should be noted that the first structural portion 111 can be a portion of the housing 11 where the functional opening 112 is provided. For example, the housing 11 includes a middle frame, and the first structural portion 111 is provided on the middle frame. The first structural portion 111 can be located on the side frame or middle plate of the middle frame, and the functional opening 112 is formed on the side frame and middle plate to connect the inside and outside of the electronic device.

[0031] The electronic device midframe can be made of metal and plastic, with the metal portion being in-mold to form a one-piece MDA midframe. The metal portion can be used to reinforce the midframe structure, serve as an antenna radiator, provide grounding, and provide electrostatic protection for, for example, the metal section 1112a in the second portion 1112. The plastic portion can be used to reduce weight, provide insulation, and provide waterproofing for the waterproof outer layer 1111b in the first portion 1111.

[0032] The first structural portion 111 can be provided in the functional opening 112, which can be a SIM card slot, a sensor installation opening, a button installation opening, or the like, though this disclosure is not limited thereto. The functional opening 112, formed as a hole or slit in the frame, can meet IP68 dust and water resistance requirements based on the above-described structure, thereby improving the overall dust and water resistance of the electronic device.

[0033] like Figure 2 As shown, the electronic device may further include a circuit board 13, which includes a third portion 133 located at the functional opening 112. The third portion 133 is provided with at least one copper leakage area 131, and the copper leakage area 131 includes a sharp-angled structure 1311 disposed toward the exterior of the electronic device. The tip effect is utilized to add a sharp-angled copper leakage area 131 to the edge of the circuit board 13 corresponding to the functional opening 112. Because the tip portion of the sharp-angled structure 1311 has a higher charge density than other portions and the electric field strength nearby is stronger, when static electricity enters the electronic device through the functional opening 112, the copper leakage area 131 with the sharp-angled structure 1311 can absorb the static electricity, thereby eliminating the harm of static electricity to other electronic components.

[0034] The copper leakage area 131 may be a triangular structure to simplify the structural arrangement of the copper leakage area 131. Alternatively, the copper leakage area 131 may be a polygon or irregular shape with a sharp corner structure 1311, which is not limited in the present disclosure.

[0035] In the above embodiment, the third portion 133 includes multiple copper leakage areas 131 arranged side by side along the length of the functional opening 112. The multiple copper leakage areas 131 along the length of the functional opening 112 absorb static electricity that enters the interior of the electronic device through the functional opening 112, thereby improving the static electricity absorption effect. For example, the static electricity absorption ranges of the sharp corner structures 1311 of two adjacent copper leakage areas 131 facing the outside of the electronic device can overlap, thereby preventing static electricity from leaking into the interior of the electronic device.

[0036] In some embodiments, the copper leakage area 131 can be set at the edge of the circuit board 13, and a gap 132 is provided between the end of the pointed structure 1311 and the side of the circuit board 13. This can not only ensure that the copper leakage area 131 at the edge of the circuit board 13 can absorb static electricity from the outside of the electronic device, but also use the above-mentioned gap 132 to avoid the influence of the copper leakage area 131 on the structure and function of the circuit board 13.

[0037] In some embodiments, Figure 1The dashed arrow in the middle may represent the thickness direction of the electronic device. In the thickness direction of the electronic device, the first structural portion 111 includes a top portion 1113 and a bottom portion 1114. When the first portion 1111 of the first structural portion 111 of the housing 11 includes a waterproof outer layer 1111b, the second portion 1112 includes a metal segment 1112a that is electrically conductively connected to the metal ground of the electronic device, and the circuit board 13 is provided with the aforementioned copper leakage area 131 at the functional opening 112, the circuit board 13 may be positioned near one of the top portion 1113 and the bottom portion 1114, with the metal segment 1112a positioned at the other of the top portion 1113 and the bottom portion 1114, so as to enhance the electrostatic protection effect by absorbing static electricity through the copper leakage area 131 located at the top portion 1113 and the bottom portion 1114, and guiding the discharge of static electricity through the metal segment 1112a.

[0038] In the above embodiment, the sealing structure 122 includes a sealing rubber ring sleeved on the main structure 121 , which abuts and seals against the first structural portion 111 in the circumferential direction, thereby utilizing the elastic properties of the sealing rubber ring itself to obtain a reliable abutting sealing effect.

[0039] In some embodiments, the second portion 1112 further includes an intermediate section 1112b extending from the first portion 1111. The intermediate section 1112b is connected to the metal section 1112a and includes a waterproof outer layer 1111b. Intermediate section 1112b is disposed between the first portion 1111 and the metal section 1112a and extends from the first portion 1111. The waterproof outer layer 1111b of intermediate section 1112b can be utilized to enhance the sealing effect at the functional opening 112, such that the connection between intermediate section 1112b and metal section 1112a is located inward of the sealing structure 122 in the depth direction of the functional opening 112. This prevents chronic corrosion and penetration of the metal components and the connection between the metal components and the first portion 1111, thereby achieving electrostatic protection while ensuring the waterproofing of the entire device.

[0040] In some embodiments, the first portion 1111 may include a metal body 1111a and a waterproof outer layer 1111b covering the metal body 1111a. The metal body 1111a may be used to increase the structural strength of the first portion 1111, and the waterproof outer layer 1111b may prevent the metal body 1111a from corrosion.

[0041] The material of the waterproof outer layer 1111b can be plastic or other waterproof materials, and the present disclosure is not limited to this.

[0042] It should be noted that the above-mentioned electronic devices can be mobile phones, tablet computers, vehicle-mounted terminals, medical terminals, wearable devices, etc., and this disclosure does not limit this.

[0043] The above description is merely a preferred embodiment of the present disclosure and does not constitute any form of limitation to the present disclosure. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not intended to limit the present disclosure. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present disclosure. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
