Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a protection component according to an embodiment of the present application, and fig. 2 is an exploded view of the protection component shown in fig. 1. The protection component 000 may include: a support 100 and a water-absorbing layer 200.

The support 100 in the protective assembly 000 may have a first opening 101.

The water absorbing layer 200 in the protective member 000 may be connected with the support 100, and a side of the water absorbing layer 200 near the support 100 may have a protrusion 201. At least a portion of the protrusion 201 may be located within the first aperture 101. By way of example, the number of the first openings 101 on the support 100 may be one or more, which is not particularly limited in the embodiments of the present application. In the following embodiments, the number of first openings 101 is taken as a plurality of examples to schematically illustrate the present invention. When the number of the first openings 101 on the support 100 is plural, the water-absorbing layer 200 has a plurality of protrusions 201 corresponding to the first openings 101 one by one, and each of the protrusions 201 may be located in the corresponding first opening 101.

In the embodiment of the present application, the protection component 000 may be installed inside the terminal device, when moisture in the external environment is immersed into the terminal device, so that the moisture can be absorbed by the convex portion 201 of the water-absorbing layer 200 distributed in the first opening 101 on the support 100, and the water-absorbing layer 200 can collect the moisture absorbed by the convex portion 201. Thus, the corrosion of the water vapor immersed in the terminal equipment to functional components (such as a main board) in the terminal equipment can be effectively avoided, and the normal operation of the terminal equipment integrated with the protection component is further ensured.

In summary, the embodiment of the present application provides a protection component, which may include: a support and a water-absorbing layer. The protection component can be installed in the inside of terminal equipment, when the steam in the external environment soaks in the terminal equipment for steam can be absorbed by the convex part of the water absorption layer that distributes in the first trompil on support piece, and the water absorption layer can collect the steam of convex part absorption. Thus, the corrosion of the water vapor immersed in the terminal equipment to functional components (such as a main board) in the terminal equipment can be effectively avoided, and the normal operation of the terminal equipment integrated with the protection component is further ensured.

In the embodiment of the present application, the front surface of the support 100 in the protective member 000 may be a hydrophilic surface, and the water absorbing layer 200 in the protective member 000 may be connected to the rear surface of the support 100. In this way, when moisture in the external environment is impregnated into the terminal device, the moisture impregnated into the terminal device is guided to the first opening 101 on the support 100 by the hydrophilic surface on the support 100 in the protection assembly 000, so that the moisture can be absorbed by the protrusions 201 of the moisture-absorbing layer 200 distributed in the first opening 101 on the support 100, and the moisture absorbed by the protrusions 201 can be collected by the moisture-absorbing layer 200.

There are various possible ways to implement the structure of the support in this application, and the following embodiments of this application are schematically illustrated by taking the following three possible ways as examples:

referring to fig. 3, fig. 3 is a cross-sectional view of a protection component according to an embodiment of the present application. The support 100 in the protection assembly 000 may include: a support body 102 connected to the water-absorbent layer 200, and a hydrophilic layer 103 located on a side of the support body 102 facing away from the water-absorbent layer 200. The side of the hydrophilic layer 103 facing away from the support body 102 may be a hydrophilic surface. The support body 102 may have a plurality of first openings 101, and the orthographic projection of the hydrophilic layer 103 on the support body 102 may not coincide with the area where the first openings 101 are located. In this case, the hydrophilic layer 103 can collect the moisture immersed in the terminal device, the collected moisture flows on the surface of the hydrophilic layer 103 and contacts with the convex portion 201 of the water absorbing layer 200 located in the first opening 101 on the support body 102, and the water absorbing layer 200 can absorb and store the moisture. In the present application, the hydrophilic layer 103 may be a film layer made of hydrophilic polyurethane (english: water Polyurethane; abbreviated: WP). It should be noted that the hydrophilic layer 103 may be a film layer made of other hydrophilic materials, which is not specifically limited in the embodiment of the present application.

Referring to fig. 4, fig. 4 is a cross-sectional view of another protection component according to an embodiment of the present application. The support 100 in the protection assembly 000 may include: the support body 102 connected to the water-absorbing layer 200, and the auxiliary layer 104 connected to the side of the support body 102 facing away from the water-absorbing layer 200, the side of the auxiliary layer 104 facing away from the support body 102 may be a hydrophilic surface. The auxiliary layer 104 may have a second opening 1041 communicating with the first opening 101. In this case, moisture immersed in the terminal device can enter the first opening 101 through the second opening 1041 on the auxiliary layer 104, and be absorbed by the convex portion 201 of the water-absorbent layer 200 located in the first opening 101.

In a third implementation manner, please refer to fig. 5 and 6, fig. 5 is an exploded view of another protection component provided in an embodiment of the present application, and fig. 6 is a cross-sectional view of the protection component shown in fig. 5. The support 100 in the protection assembly 000 may include: an auxiliary layer 104, and a hydrophilic layer 103 applied to the side of the auxiliary layer 104 facing away from the support body 102. The auxiliary layer 104 may be connected to a side of the support body 102 facing away from the water-absorbent layer 200. The auxiliary layer 104 has a second opening 1041 communicating with the plurality of first openings 101. The side of the hydrophilic layer 103 facing away from the support body 102 may be a hydrophilic surface. Wherein the orthographic projection of the hydrophilic layer 103 on the support body 102 does not coincide with the orthographic projection of the second opening 1041 on the auxiliary layer 104 on the support body 102. In this case, when moisture in the external environment is immersed in the terminal device, the moisture immersed in the terminal device can be collected through the hydrophilic layer 103 provided on the side of the auxiliary layer 104 facing away from the support body 102, and the collected moisture flows on the surface of the hydrophilic layer 103 and flows to the first opening 101 of the support body 102 communicating with the second opening 1041 through the second opening 1041 of the auxiliary layer 104. And contacts the convex portion 201 of the water-absorbing layer 200 located in the first opening 101 on the support body 102, the water-absorbing layer 200 is capable of absorbing and storing such moisture. In the present application, the auxiliary layer 104 in the support 100 may be a film layer structure made of a polycondensate of terephthalic acid and ethylene glycol (english: polyethylene terephthalate; abbreviated: PET). When the auxiliary layer 104 is made of PET material, the hydrophilic layer 103 can be well coated on the surface of the auxiliary layer 104, that is, the adhesion performance between the hydrophilic layer 103 and the auxiliary layer 104 is ensured to be good. It should be noted that the auxiliary layer 104 may also be made of other materials, such as Polypropylene (PP), which is not specifically limited in the embodiment of the present application.

In addition, when the support member body 102 is disposed on the side facing away from the water-absorbing layer 200, in order to ensure the stability of the lamination between the support member body 102 and the support member 104, the height of the protrusion 201 located in the first opening 101 facing away from the water-absorbing layer 200 is less than or equal to the height of the support member body 102 facing away from the water-absorbing layer 200.

In this embodiment, there are various possible manners for the positional relationship between the plurality of second openings 1041 on the auxiliary layer 104 and the plurality of first openings 101 on the support body 102, and the present application will be schematically described in the following two possible manners:

referring to fig. 6 and 7, fig. 7 is an exploded schematic view of an auxiliary layer and a support body according to an embodiment of the present application. The orthographic projection of the second opening 1041 on the auxiliary layer 104 in the support 100 on the support body 102 may not coincide with the area where the first opening 101 on the support body 102 is located. The side of the auxiliary layer 104 near the support body 102 may have: a communication groove 1042 for communicating with each of the second openings 1041. The orthographic projection of the communication groove 1042 on the support body 102 may overlap with the areas where the plurality of first openings 101 on the support body 102 are located. In this case, the water vapor immersed in the terminal device is collected by the hydrophilic layer 103 on the auxiliary layer 104 and is collected at the second opening 1041 on the auxiliary layer 104. The collected water vapor flows to the positions of the plurality of first openings 101 under the action of the gravity of the water vapor and the capillary action of the communicating grooves 1042, and is finally absorbed by the water absorbing layer 200 positioned in the first openings 101. In addition, after the water vapor flows into the communication groove 1042 on the side of the auxiliary layer 104 facing away from the hydrophilic layer 103, the water vapor is not easily volatilized to the outside of the protection assembly 000 again by shielding of the auxiliary layer 104. For example, the communicating grooves 1042 may be mesh communicating grooves, or may be formed by a plurality of parallel rows of flow guiding grooves or a plurality of parallel columns of flow guiding grooves, and the specific structure of the communicating grooves 1042 is not specifically limited in this embodiment.

In a second implementation manner, please refer to fig. 8, fig. 8 is a cross-sectional view of still another protection component provided in an embodiment of the present application. The plurality of first openings 101 on the support body 102 and the plurality of second openings 1041 on the auxiliary layer 104 may be in one-to-one correspondence. The orthographic projection of each second aperture 1041 on the support body 102 may at least partially overlap with the area where the corresponding first aperture 101 is located. In this case, the moisture immersed in the terminal device may flow directly into the first opening 101 on the support body 102 through the second opening 1041 on the auxiliary layer 104 and be absorbed by the convex portion 201 of the water-absorbing layer 200 located in the first opening 101. For example, the orthographic projection of each second aperture 1041 on the support body 102 may be located in the area of the corresponding first aperture 101. It should be noted that, in other possible implementations, when the front projection of each second opening 1041 on the support body 102 may be located in the area where the corresponding first opening 101 is located, a side of the auxiliary layer near the support body 102 may also have a communication slot 1042.

Optionally, referring to fig. 9 and fig. 10, fig. 9 is a schematic diagram illustrating a positional relationship between an auxiliary layer and a first opening on a support body according to an embodiment of the present application, and fig. 10 is a front view of the auxiliary layer according to an embodiment of the present application. The plurality of second openings 1041 on the auxiliary layer 104 may be arranged in an array in a plurality of rows and/or a plurality of columns. The communication groove 1042 on the side of the auxiliary layer 104 near the support body 102 may include: a first flow guide 1042a located between every two adjacent rows of second openings 1041, and a second flow guide 1042b located between every two adjacent columns of second openings 1041. The first diversion trench 1042a is respectively communicated with the second openings 1041 on two sides of the first diversion trench 1042a, and the second diversion trench 1042b is respectively communicated with the second openings 1041 on two sides of the second diversion trench 1042b.

In this embodiment, as shown in fig. 6 and 9, when the orthographic projection of the second opening on the auxiliary layer 104 on the support body 102 is not coincident with the area where the first opening 101 is located, the orthographic projection of the intersection position of the first diversion trench 1042a and the second diversion trench 1042b on the support body 102 may be located in the area where the first opening 101 on the support body 102 is located. In this case, since the plurality of second openings 1041 on the auxiliary layer 104 are arranged in a plurality of rows and/or a plurality of columns, the first diversion trench 1042a is disposed between every two adjacent rows of the second openings 1041, and the second diversion trench 1042b is disposed between every two adjacent columns of the second openings 1041, i.e. the communication trench 1042 may include a plurality of first diversion trenches 1042a and a plurality of second diversion trenches 1042b. Therefore, the efficiency of attracting the moisture collected at the second openings 1041 to the areas where the plurality of first openings 101 are located can be improved by the plurality of first diversion trenches 1042a and the plurality of second diversion trenches 1042b. Which in turn causes the water vapor to be absorbed by the water absorbent layer 200 located within the first opening 101.

In this application, the number of the first diversion trenches 1042a in the communication groove 1042 may be plural, the number of the second diversion trenches 1042b may be plural, and the arrangement directions of the first diversion trenches 1042a and the second diversion trenches 1042b are mutually perpendicular. In addition, the plurality of first diversion trenches 1042a and the plurality of second diversion trenches 1042b may be formed with a plurality of intersecting positions, the plurality of intersecting positions are in one-to-one correspondence with the plurality of first openings 101 on the support body 102, and orthographic projections of the intersecting positions formed by each first diversion trench 1042a and each second diversion trench 1042b on the support body 102 are located in the area where the corresponding first opening 101 is located.

In the embodiment of the present application, as shown in fig. 10, the communication groove 1042 on the side of the auxiliary layer 104 near the support body 102 may further include: a first auxiliary diversion trench 1042c for communicating the second opening 1041 with the first diversion trench 1042a, and a second auxiliary diversion trench 1042d for communicating the second opening 1041 with the second diversion trench 1042b. In this case, by providing the first auxiliary diversion trench 1042c between the second opening 1041 and the first diversion trench 1042a and providing the second auxiliary diversion trench 1042d between the second opening 1041 and the second diversion trench 1042b, the efficiency of attracting the water vapor collected at the second opening 1041 to the first diversion trench 1042a and the second diversion trench 1042b can be effectively improved, and then the water vapor is attracted to the areas where the plurality of first openings 101 are located through the first diversion trench 1042a and the second diversion trench 1042b.

Alternatively, as shown in fig. 10, the communication groove 1042 on the side of the auxiliary layer 104 near the supporter body 102 may further include: the third auxiliary diversion trenches 1042e can be distributed around the plurality of second openings 1041. The end of the first diversion trench 1042a and the end of the second diversion trench 1042b may be connected with the third auxiliary diversion trench 1042 e. In this case, by providing the third auxiliary diversion trench 1042e in the peripheral area of the plurality of second openings 1041, and the third auxiliary diversion trench 1042e is communicated with the end portion of the first diversion trench 1042a and the end portion of the second diversion trench 1042b, the water vapor in the first diversion trench 1042a and the second diversion trench 1042b can be attracted into the third auxiliary diversion trench 1042e, so as to further improve the attraction effect of the first diversion trench 1042a, the second diversion trench 1042b and the third auxiliary diversion trench 1042e on the water vapor. For example, the third auxiliary diversion trench 1042e may be an annular diversion trench, and the plurality of second openings 1041 may be located in an area surrounded by the annular diversion trench.

In the embodiment of the present application, as shown in fig. 10, the communication groove 1042 on the side of the auxiliary layer 104 near the support body 102 may further include: and a fourth auxiliary diversion trench 1042f for communicating the second aperture 1041 with the third auxiliary diversion trench 1042 e. In this case, the water vapor collected at the second opening 1041 can not only attract the water vapor into the first diversion trench 1042a through the first auxiliary diversion trench 1042c, but also attract the water vapor into the second diversion trench 1042b through the second auxiliary diversion trench 1042d, and attract the water vapor into the third diversion trench 1042e through the fourth auxiliary diversion trench 1042f. In this way, the efficiency of attracting the moisture collected at the second opening 1041 is further improved. I.e., the water absorption effect of the protection component 000 is prevented from being affected by too much water vapor collected at the second opening 1041.

Alternatively, the depth of the diversion trench provided on the side of the auxiliary layer 104 near the support body 102 may be in the range of: the width of the diversion trench can range from 0.03mm to 0.06 mm: 0.05mm to 0.1mm. For example, the depth of the channels may be 0.05 millimeters and the width of the channels may be 0.06 millimeters. Namely, the depth and width of the first and second guide grooves 1042a, 1042b, 1042c, 1042d, 1042e and 1042f in the communication groove 1042 may be the same. In this way, the communication groove 1042 is formed on the side of the auxiliary layer 104 near the supporting member body 102. It should be noted that, in other possible implementations, the depth and width of the first diversion trench 1042a, the depth and width of the second diversion trench 1042b, the depth and width of the first auxiliary diversion trench 1042c, the depth and width of the second auxiliary diversion trench 1042d, the depth and width of the third auxiliary diversion trench 1042e and the depth and width of the fourth auxiliary diversion trench 1042f in the communication groove 1042 may be partially different, or may be different, which is not specifically limited in this embodiment.

Alternatively, referring to fig. 11, 12 and 13, fig. 11 is a schematic structural view of another protection component provided in an embodiment of the present application, fig. 12 is an exploded view of the protection component shown in fig. 11, and fig. 13 is a sectional view of the protection component shown in fig. 11. One side of the support body 102 may have a mounting groove 1021, and the plurality of first openings 101 may communicate with the mounting groove 1021, and the water-absorbing layer 200 in the protection assembly 000 may be fixed in the mounting groove 1021. In this case, by disposing the water-absorbing layer 200 in the mounting groove 1021 in the support body 102, the water vapor absorbed by the water-absorbing layer 200 can be prevented from volatilizing the protective component 000 from the side of the water-absorbing layer 200. For example, the support body 102 and the water-absorbing layer 200 may be formed by two-shot molding, i.e., the support body 102 may be formed by injection molding and then the water-absorbing layer 200 may be formed by injection molding. It should be noted that, in the first possible manner described above, the mounting groove 1021 may be provided on the side of the support member body 102 facing away from the hydrophilic layer 103. In a second realisable way, the mounting groove 1021 may be provided on the side of the support body 102 facing away from the auxiliary layer 104.

In the embodiment of the present application, when the water vapor absorbed by the water absorbent layer 200 is more, in order to prevent the water vapor in the water absorbent layer 200 from volatilizing from the notch of the installation groove 1021 in the support body 102. Referring to fig. 11, 12 and 13, the protection component may further include: protective cover 300, protective cover 300 can be connected with support piece body 102 one side that sets up mounting groove 1021, and protective cover 300 can cover the mounting groove 1021 on support piece body 102. In this way, a cavity can be formed by the protective cover 300 and the mounting groove 1021 of the support body 102, and the water absorbing layer 200 can be located in this cavity.

Alternatively, as shown in fig. 13, a space C1 may be provided between the side of the water-absorbing layer 200 in the protection member 000 facing away from the support member body 102 and the protection cover 300. In this case, when the water absorbent layer 200 absorbs more water vapor, the water absorbent layer 200 may expand somewhat. By arranging the gap C1 between the side of the water absorbing layer 200 facing away from the support body 102 and the protective cover 300, the gap C1 can provide a certain space for the expansion of the water absorbing layer 200, so as to avoid the adverse phenomenon that the protective cover 300 falls off from the support body 102 due to the acting force exerted by the expanded water absorbing layer 200 on the protective cover 300. Illustratively, the width of this void C1 may range between 0.15 millimeters and 0.25 millimeters, for example, the width of the void C1 may be 0.2 millimeters.

In this embodiment, as shown in fig. 12 and 13, the water-absorbent layer 200 includes a water-absorbent layer body 202, and a protrusion 201 connected to a side of the water-absorbent layer body 202 near the support member 100, and a side of the protrusion 201 facing away from the water-absorbent layer body 202 may have a groove structure 2011. In this case, the water vapor is condensed at the groove structure 2011 on the convex portion 201, and the condensed water vapor is collected into the groove structure 2011 under the action of gravity. When more water vapor is collected in the groove structure 2011, the tension of the water vapor is larger, so that the water vapor is convenient to be absorbed on the water absorbing layer 200 and absorbed by the water absorbing layer 200.

Alternatively, the water-absorbing layer 200 in the protection assembly 000 may be a film structure made of at least one of Acrylic acid (Aa) and Maleic anhydride (Ma). Wherein, both acrylic acid and maleic anhydride have good water absorbability and can store water of 20 to 40 times more than their own weight. It should be noted that the water-absorbing layer 200 in the present application may be made of other materials having water-absorbing properties, such as super absorbent resin.

The embodiment of the application also provides a terminal device, which comprises but is not limited to: a mobile phone, a tablet computer, an iPad, a digital broadcast terminal, a messaging device, a game console, a medical device, a fitness device, a personal digital assistant, an intelligent wearable device, an intelligent television, and the like. Referring to fig. 14, fig. 14 is a schematic structural diagram of a terminal device according to an embodiment of the present application. The terminal device may comprise a protection component 000, wherein the protection component 000 may be any of the protection components given above.

Optionally, as shown in fig. 14, the terminal device may further include: the housing 001, and the functional part 002 mounted in the housing 001 in the terminal device, the protection assembly 000 is mounted in the housing 001, and the front surface of the support 100 in the protection assembly 000 may face the functional part 002. By way of example, the functional component 002 may include: and the main board in the terminal equipment and the electronic element positioned on the main board. Thus, when the water vapor in the external environment is immersed into the terminal equipment, the protection component 000 close to the functional component 002 can absorb the water vapor, and then the probability of corroding the functional component by the water vapor can be reduced.
