The auxiliary layer 104 has second openings 1041 connected 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. 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 water vapor in the external environment infiltrates into the terminal equipment, the hydrophilic layer 103 provided on the side of the auxiliary layer 104 facing away from the support body 102 can collect the water vapor infiltrated into the terminal equipment. , the collected water vapor flows on the surface of the hydrophilic layer 103, and flows through the second opening 1041 on the auxiliary layer 104 to the first opening 101 on the support body 102 that is connected to the second opening 1041.

Optionally, as shown in FIG. 13 , there may be a gap C1 between the side of the water-absorbent layer 200 in the protective assembly 000 facing away from the support body 102 and the protective cover 300 . In this case, when the water-absorbent layer 200 absorbs more water vapor, the water-absorbent layer 200 may expand to a certain extent. By providing a gap C1 between the side of the water-absorbent 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-absorbent layer 200 and prevent the expanded water-absorbent layer 200 from damaging the protective cover 300 Applying force causes the protective cover 300 to fall off from the support body 102 . For example, the width of the gap C1 may range from 0.15 mm to 0.25 mm. For example, the width of the gap C1 may be 0.2 mm.

In the embodiment of the present application, as shown in Figures 12 and 13, the water-absorbent layer 200 includes a water-absorbent layer body 202, and a convex portion 201 connected to the side of the water-absorbent layer body 202 close to the support 100. The convex portion 201 is away from the water-absorbent layer. One side of the body 202 may have a groove structure 2011. In this case, water vapor will condense at the groove structure 2011 on the convex part 201, and the condensed water vapor will gather into the groove structure 2011 under its own gravity. When more water vapor accumulates in the groove structure 2011, the tension of the water vapor becomes greater, which facilitates the water vapor to be adsorbed onto the water-absorbent layer 200 and absorbed by the water-absorbent layer 200.

Optionally, the water-absorbent layer 200 in the protective component 000 may be a film layer made of at least one of acrylic acid (English: Acrylic acid; abbreviation: Aa) and maleic anhydride (English: Maleic anhydride; abbreviation: Ma). structure. Among them, acrylic acid and maleic anhydride both have good water absorption and can store water 20 to 40 times greater than their own weight. It should be noted that the water-absorbent layer 200 in this application can also be made of other water-absorbent materials, such as super-absorbent resin.

To sum up, embodiments of the present application provide a protective component, which may include: a support member and a water-absorbent layer. The protection component can be installed inside the terminal equipment. When water vapor in the external environment is immersed into the terminal equipment, the water vapor can be absorbed by the convex portions of the water-absorbent layer distributed in the first opening on the support member, and the water-absorbent layer can Collect the water vapor absorbed by the convex part. In this way, corrosion of functional components (such as the motherboard) in the terminal device by water vapor immersed in the terminal device can be effectively avoided, thereby ensuring the normal operation of the terminal device with integrated protection components.

Embodiments of the present application also provide a terminal device, which includes but is not limited to: mobile phones, tablet computers, iPads, digital broadcast terminals, message transceiver devices, game consoles, medical equipment, fitness equipment, personal digital assistants, smart phones, etc. Wearable devices and smart TVs, etc. Please refer to Figure 14, which is a schematic structural diagram of a terminal device provided by an embodiment of the present application. The terminal device may include a protection component 000, where the protection component 000 may be any of the protection components given above.

Optionally, as shown in Figure 14, the terminal device may also include: a shell 001, and a functional component 002 installed in the shell 001 in the terminal device, the protection component 000 is installed in the shell 001, and the protection component 000 The front side of the support 100 may face the functional component 002 . For example, the functional component 002 may include: a mainboard in the terminal device and electronic components located on the mainboard. In this way, when water vapor in the external environment infiltrates into the interior of the terminal device, the protection component 000 disposed close to the functional component 002 can absorb the water vapor, thereby reducing the probability that the water vapor will corrode the functional component.
