In the process of conceiving and implementing the present application, it is found that in some intelligent terminals, there are at least the following problems: there is a gap between the edge of the liquid crystal display screen and the middle frame of the intelligent terminal. After corrosive liquid penetrates and contacts the display layer of the liquid crystal display screen for a long time, it may cause damage to the liquid crystal display screen, affecting the reliability and service life of the intelligent terminal device.

[0004] The foregoing description is for providing general background information and does not necessarily constitute prior art. Summary of the Utility Model

[0005] In view of the above technical problems, the present application provides an anti-corrosion structure and an intelligent terminal, which solve the technical problem that corrosive liquid is likely to contact the display layer of the liquid crystal display screen for a long time, resulting in damage to the liquid crystal display screen, and improve the reliability and service life of the intelligent terminal device.

[0006] To solve the above technical problems, the present application provides an anti-corrosion structure, including:

[0008] A display component, which is arranged in the receiving cavity, and the edge of the display component blocks the opening end of the drainage groove;

[0009] A cover plate, which is arranged on the display component.

[0010] An anti-corrosion structure provided by the present application solves the technical problem that the reliability and service life of the display component are affected due to corrosive liquid contacting and soaking the display layer of the display component for a long time by adding a drainage groove in the middle frame and blocking the edge of the display component at the opening end of the drainage groove, so that the liquid entering between the edge of the display component and the middle frame can be collected in the drainage groove.

[0011] In a possible implementation manner, an installation platform is provided on the inner wall of the middle frame, the display component abuts against the installation platform, and the drainage groove is formed in the installation platform.

[0012] In a possible implementation manner, the display component is connected to the installation platform through an adhesive, and the drainage groove is located between the adhesive and the inner wall of the middle frame;

[0013] There is a spacing L1 between the adhesive and the drainage groove, where 0.3 mm ≤ L1 ≤ 0.6 mm.

[0014] In a possible implementation manner, the drainage groove is recessed from the upper surface of the installation platform towards the inside of the installation platform, and the recessed depth of the drainage groove is H, where 0.2 mm ≤ H ≤ 0.4 mm; and / or,

[0015] The width of the drainage groove is L2, where 0.8 mm ≤ L2 ≤ 1.5 mm.

[0016] In a possible implementation manner, the display component includes a display layer and a composite layer. Along the thickness direction of the display component, the edge of the projection of the display layer extends beyond the edge of the projection of the composite layer;

[0017] An overflow channel is formed between the edge of the display layer and the inner wall of the drainage groove.

[0018] In a possible implementation manner, the inner wall of the drainage groove has a convex platform, and the convex platform is located on the side of the drainage groove away from the adhesive;

[0019] Along the thickness direction of the display component, at least part of the projection of the cover plate coincides with the projection of the convex platform.

[0020] In a possible implementation manner, there is a first channel between the edge of the cover plate and the convex platform, and a second channel between the side of the cover plate facing the display component and the convex platform.

[0021] In a possible implementation manner, a drain hole is further formed in the middle frame. The first end of the drain hole is communicated with the drainage groove, and the second end of the drain hole penetrates through the outer wall of the middle frame.

[0022] In a possible implementation manner, from the first end of the drain hole to the second end of the drain hole, the drainage groove gradually inclines towards the direction close to the outer bottom wall of the middle frame.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this text, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "upon" or "in response to determining".

[0048] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] In subsequent descriptions, the use of suffixes such as "module", "component", or "unit" to represent elements is only for the convenience of the description of the present application, and they have no specific meaning in themselves. Therefore, "module", "component", or "unit" can be used interchangeably.

[0050] The intelligent terminal can be implemented in various forms. For example, the intelligent terminal described in the present application can include intelligent terminals such as mobile phones, tablet computers, laptop computers, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, intelligent bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0051] Generally, there is no tight fit between the display component and the inner wall of the middle frame, and there is a small gap between the display component and the inner wall of the middle frame, which can reduce the problem of the display component hitting the inner wall of the middle frame and causing damage to the display component in case of accidental situations such as dropping or collision of the intelligent terminal, thereby protecting the display component. However, since there is a small gap between the display component and the inner wall of the middle frame, it will cause liquids such as rainwater to enter. If the entered liquid contacts the display layer of the display component for a long time, it is easy to corrode the display layer and affect the reliability and service life of the display component.

[0052] In view of this, an anti-corrosion structure provided by the present application adds a drainage groove in the middle frame, so that the liquid entering between the edge of the display component and the middle frame can be collected in the drainage groove, solving the technical problem that the corrosive liquid contacts and soaks the display layer of the display component for a long time, resulting in affecting the reliability and service life of the display component, thereby ensuring the service life of the display component.

[0053] Next, an anti-corrosion structure and an intelligent terminal provided by an embodiment of the present application will be described with reference to the accompanying drawings.

[0054] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides an anti-corrosion structure, including: a middle frame 10, a display component 20 and a cover plate 30. The middle frame 10 has a receiving cavity 11 and a drainage groove 13, and the drainage groove 13 is located at the edge of the receiving cavity 11; the display component 20 is disposed in the receiving cavity 11, and the edge of the display component 20 covers the opening end of the drainage groove 13; the cover plate 30 is disposed on the display component 20.

[0055] An anti-corrosion structure provided by the present application adds a drainage groove 13 in the middle frame 10, and covers the edge of the display component 20 at the opening end of the drainage groove 13, so that the liquid entering between the edge of the display component 20 and the middle frame 10 can be collected in the drainage groove 13, solving the technical problem that the corrosive liquid contacts and soaks the display layer 21 of the display component 20 for a long time, resulting in affecting the reliability and service life of the display component 20.

[0056] The cover plate 30 can be made of a transparent material, and the cover plate 30 serves to protect the display component 20. For example, the cover plate 30 is made of transparent glass material.

[0057] In a possible implementation manner, refer to Figure 4 and Figure 5 As shown, an installation table 12 is provided on the inner wall of the middle frame 10. The display component 20 abuts against the installation table 12, and the drainage groove 13 is opened in the installation table 12. The opening end of the drainage groove 13 faces upward of the middle frame 10, and the opening end of the drainage groove 13 is an open end.

[0058] In a possible implementation manner, the installation table 12 can be a ring of bosses provided around the inner wall surface of the middle frame 10. The installation table 12 serves to position and support the display component 20, and the display component 20 can be fixed on the installation table 12 by means of bonding.

[0059] In a possible implementation manner, the middle frame 10 further includes a connecting plate at the bottom of the receiving cavity 11, and the edge of the connecting plate can be connected to the installation table 12.

[0060] In a possible implementation manner, referring to Figure 6 , Figure 7 and Figure 8 as shown, the drainage groove 13 can be located at at least one side edge of the accommodation cavity 11. For example, the drainage groove 13 can be located at both side edges in the width direction of the accommodation cavity 11 and at least one side edge in the length direction of the accommodation cavity 11. The two side edges in the width direction of the accommodation cavity 11 are respectively the left side edge and the right side edge of the accommodation cavity 11. The drainage groove 13 located at the left side edge of the accommodation cavity 11 and the drainage groove 13 located at the left side edge of the accommodation cavity 11 can be independent of each other or interconnected, so as to increase the liquid storage volume of the drainage groove 13.

[0061] In a possible implementation manner, referring to Figure 2 and Figure 3 as shown, the display component 20 is connected to the mounting table 12 through an adhesive member 40, and the drainage groove 13 is located between the adhesive member 40 and the inner wall of the middle frame 10. There is a spacing L1 between the adhesive member 40 and the drainage groove 13, where 0.3 mm ≤ L1 ≤ 0.6 mm.

[0062] In a possible implementation manner, in order to improve the fixing stability of the display component 20, the adhesive member 40 pastes and fixes the display component 20 to the mounting table 12 along the circumferential side of the display component 20.

[0063] The existence of the spacing L1 between the adhesive member 40 and the drainage groove 13 can prevent the adhesive member 40 from directly contacting the corrosive liquid entering the drainage groove 13, playing a role in protecting the adhesive member 40. In addition, due to the installation error or dimensional error of the adhesive member 40, it is difficult to accurately fix the position of the adhesive member 40 on the mounting table 12. The existence of the spacing L1 can prevent the edge of the adhesive member 40 from extending above the drainage groove 13, causing the adhesive member 40 to block the opening end of the drainage groove 13, thereby avoiding the adhesive member 40 affecting the liquid collection of the drainage groove 13 and ensuring a stable use effect.

[0064] In a possible implementation manner, the adhesive member 40 includes but is not limited to double-sided tape, glue, etc.

[0065] In a possible implementation manner, the spacing L1 between the adhesive member 40 and the drainage groove 13 can be, for example, 0.3 mm, 0.4 mm, 0.5 mm, or 0.6 mm.

[0066] In a possible implementation manner, the drainage groove 13 is recessed from the upper surface of the mounting table 12 into the mounting table 12, and the recessed depth of the drainage groove 13 is H, where 0.2 mm ≤ H ≤ 0.4 mm. The greater the recessed depth of the drainage groove 13, the more conducive it is to collecting and storing more liquid. However, if the recessed depth of the drainage groove 13 is too large, it will affect the structural strength of the mounting table 12. Therefore, in this application, by making 0.2 mm ≤ H ≤ 0.4 mm, it can not only meet the function of the drainage groove 13 for collecting liquid, but also ensure the structural strength of the mounting table 12.

[0067] In a possible implementation manner, the recessed depth H of the drainage groove 13 can be, for example, 0.2 mm, 0.3 mm, 0.35 mm or 0.4 mm.

[0068] In a possible implementation manner, the width of the drainage groove 13 is L2, where 0.8 mm ≤ L2 ≤ 1.5 mm. If the width L2 of the drainage groove 13 is too large, it will affect the supporting effect of the mounting table 12 on the display component 20. If the width L2 of the drainage groove 13 is too small, it will affect the effect of collecting liquid. In this application, by making 0.8 mm ≤ L2 ≤ 1.5 mm, it ensures the supporting effect of the mounting table 12 on the display component 20 and the effect of collecting liquid, and has good comprehensive capabilities.

[0069] In a possible implementation manner, the width L2 of the drainage groove 13 can be, for example, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.4 mm or 1.5 mm.

[0070] In a possible implementation manner, the display component 20 includes a display layer 21 and a composite layer 22. Along the thickness direction of the display component 20, the edge of the projection of the display layer 21 extends beyond the edge of the projection of the composite layer 22; an overflow channel 14 is formed between the edge of the display layer 21 and the inner wall of the drainage groove 13.

[0071] In a possible implementation manner, along the length direction of the display component 20, the two side edges of the display layer 21 respectively extend beyond the two side edges of the composite layer 22. Along the width direction of the display component 20, the two side edges of the display layer 21 respectively extend beyond the two side edges of the composite layer 22, that is, compared with the composite layer 22, the display layer 21 has a larger length and width.

[0072] In this application, by forming the overflow channel 14 between the edge of the display layer 21 and the inner wall of the drainage groove 13, the liquid entering from between the edge of the cover plate 30 and the inner wall of the middle frame 10 enters the drainage groove 13 through the overflow channel 14, reducing the contact time of the liquid with the display layer 21, thereby solving the problem of damage to the display layer 21 caused by long-term immersion of the display layer 21.

[0073] In a possible implementation, along the thickness direction of the display component 20, the projection of the composite layer 22 may not overlap with the projection of the drainage groove 13, that is, the drainage groove 13 does not extend below the composite layer 22, which can reduce the area of the composite layer 22 in contact with the liquid and play a role in protecting the composite layer 22 from corrosion. Of course, the projection of the composite layer 22 may also overlap with the projection of the drainage groove 13, that is, the drainage groove 13 extends from below the display layer 21 to below the composite layer 22, so that the drainage groove 13 has a larger storage volume.

[0074] In a possible implementation, the display layer 21 includes a polarizing layer 211, a panel layer 212, and a support layer 213 that are sequentially stacked. Among them, the polarizing layer 211 is connected to the lower surface of the cover plate 30 through an optical adhesive layer 23. The composite layer 22 includes an adhesive layer 221, a buffer layer 222, and a heat dissipation layer 223 that are sequentially stacked. One side of the adhesive layer 221 facing away from the buffer layer 222 is connected to the support layer 213. The adhesive layer 221 may be a reticulated adhesive, for example, the buffer layer 222 may be a foam layer, and the heat dissipation layer 223 may be a copper foil layer, for example.

[0075] In a possible implementation, the inner wall of the drainage groove 13 has a boss 15, and the boss 15 is located on the side of the drainage groove 13 away from the bonding member 40.

[0076] In a possible implementation, along the thickness direction of the display component 20, the projection of the cover plate 30 and the projection of the boss 15 at least partially overlap. That is, the edge of the cover plate 30 covers the boss 15, and the boss 15 plays a role in defining the position of the cover plate 30, preventing the cover plate 30 from moving towards the display component 20 and causing the problem of the display component 20 being squeezed and damaged, which helps to protect the display component 20.

[0077] In a possible implementation, there is a first channel 16 between the edge of the cover plate 30 and the boss 15, and a second channel 17 between the side of the cover plate 30 facing the display component 20 and the boss 15. By providing the first channel 16 and the second channel 17, there is a certain buffer space between the cover plate 30 and the boss 15, which can prevent the problem of the cover plate 30 being damaged by hitting the boss 15 when the intelligent terminal drops or has other accidents.

[0078] In a possible implementation manner, a liquid discharge hole (not shown in the figure) is also formed in the middle frame 10. The first end of the liquid discharge hole communicates with the drainage groove 13, and the second end of the liquid discharge hole penetrates through the outer wall of the middle frame 10. The liquid discharge hole is a through hole, which communicates the drainage groove 13 with the external environment of the middle frame 10, so that the liquid collected in the drainage groove 13 can be discharged to the outside of the smart terminal, preventing the display layer 21 of the display component 20 from being soaked due to excessive liquid collected in the drainage groove 13, and helping to ensure the service life of the display component 20.

[0079] In a possible implementation manner, the first end of the liquid discharge hole is located on the bottom wall surface of the drainage groove 13, which helps to reduce the liquid residue in the drainage groove 13 when discharging the liquid collected in the drainage groove 13, and improves the liquid discharge effect in the drainage groove 13.

[0080] In a possible implementation manner, from the first end to the second end of the liquid discharge hole, the drainage groove 13 gradually inclines towards the direction close to the outer bottom wall of the middle frame 10. Such a structure makes the liquid discharge hole inclined relative to the horizontal plane, and the drainage groove 13 plays a certain guiding role, so that the liquid collected in the drainage groove 13 can be smoothly discharged through the liquid discharge hole.

[0081] In a possible implementation manner, the first end of the liquid discharge hole is in a flared shape, which is beneficial to the liquid collected in the drainage groove 13 to enter the liquid discharge hole.

[0082] In a possible implementation manner, the number of liquid discharge holes can be one, or two or more, so that the liquid collected in the drainage groove 13 can be discharged in time.

[0083] The present application also provides a smart terminal, including a main body and the above anti-corrosion structure, and the anti-corrosion structure is arranged on the main body.

[0084] In a possible implementation manner, the main body includes a bottom shell, a circuit board, etc., and the bottom shell is arranged on the bottom wall surface of the middle frame 10.

[0085] In the following description, a mobile terminal will be taken as an example for illustration. Those skilled in the art will understand that, except for the components specifically used for mobile purposes, the structure according to the embodiments of the present application can also be applied to fixed-type terminals.

[0086] Please refer to Figure 9As shown, it is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application.

The mobile terminal can help users send and receive emails, browse the web, and access streaming media through the WiFi module 502. It provides users with wireless broadband Internet access. Although Figure 9 the WiFi module 502 is shown, it can be understood that it does not belong to the essential components of the mobile terminal and can be omitted entirely within the scope of not changing the essence of the application as needed.

[0090] The audio output unit 503 can convert the audio data received by the radio frequency unit 501 or the WiFi module 502 or stored in the memory 509 into an audio signal and output it as sound when the mobile terminal 500 is in modes such as a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, etc. Moreover, the audio output unit 503 can also provide an audio output related to a specific function executed by the mobile terminal 500 (e.g., a call signal reception sound, a message reception sound, etc.).
