Description

Technical Field

[0001] The utility model relates to the technical field of water-proof shells, in particular to a shell with a water-proof function. Background Art

[0002] As society has entered the information age, people will carry electronic devices with them when they travel. However, due to the immaturity of technology, the storage capacity of electronic devices is far from enough to meet people's needs, so people need mobile charging devices to charge their electronic devices. Power banks are large-capacity portable power sources that are easy to carry and are portable devices that integrate power storage, voltage boosting, and charging management, so power banks have become a necessity for people. The charging plug of the power bank itself can charge mobile devices directly through an AC power supply and has a power storage device, which is equivalent to a hybrid of a charger and a backup battery. Compared with a backup power supply, the device of a charging plug can be simplified, and compared with a charger, it has a power storage device, which can provide backup power for digital products when there is no direct power supply or when going out. However, during the charging process of existing power banks, part of the electrical energy will be converted into internal energy, which will cause the power bank to heat up, and a large amount of heat accumulation will cause an explosion.

[0003] Chinese patent CN214154103U discloses a power bank shell with waterproof and heat dissipation functions, including a shell body, a groove, a charging port, a heat dissipation structure and a waterproof baffle. The bottom end of the shell body is provided with a groove, and the bottom of the shell body above the groove is provided with a charging port, and the bottom ends of the shell body on both sides of the groove are provided with through grooves, and the inside of the groove is provided with a waterproof baffle, and a convex ridge is fixed on the outer wall of one side of the waterproof baffle, and the heat dissipation structure is provided on both sides of the bottom of the shell body, and a storage cover is fixed on the top of the shell body, and a first storage rod is fixed on both sides of the storage cover, and a second storage rod is mounted on the outer wall of the first storage rod, and the second storage rod is slidably connected with the first storage rod. This patent not only realizes the waterproof function and improves the heat dissipation effect of the shell, but also realizes the storage function of the data line. However, the storage of the data line in the structure of the patent is more widely reflected, so the waterproof effect is not ideal, and it is still easy to cause water to enter the power bank, causing it to be damaged. Therefore, a shell with a water-proof function is proposed to address the above shortcomings. Utility Model Content

[0004] The purpose of the utility model is to provide a shell with a water-proof function in order to solve the above-mentioned problem. The waterproof board blocks the water source to further prevent water. If there is too much water, the second absorbent cotton will absorb the water internally. The weight of the second absorbent cotton is borne by the connecting frame, thereby solving the problems mentioned in the background technology.

[0005] In order to solve the above problems, the utility model provides a technical solution:

[0006] A shell with a water-proof function comprises an upper protective shell and a lower protective shell, wherein first absorbent cotton is fixedly connected to the interior of both ends of the upper protective shell, waterproof plates are fixedly connected to the interior of both ends of the upper protective shell, the waterproof plates abut against the first absorbent cotton, an inner cavity is defined inside the upper protective shell, a plurality of springs are fixedly connected to the interior of the inner cavity on both sides, a connecting plate is fixedly connected to the other ends of the plurality of springs, a connecting frame is fixedly connected to the upper surface of the connecting plate, and a plurality of second absorbent cottons are fixedly connected to the interior of the connecting frame.

[0007] As a preferred solution of the utility model, card slots are provided inside the two sides of the lower protective shell, and the inside of the card slots is fixedly connected to limit blocks.

[0008] As a preferred solution of the utility model, connecting rods are fixedly connected to the lower surfaces of both sides of the upper protective shell, the bottom ends of the connecting rods are fixedly connected to fixing rods, the lower surfaces of the fixing rods are fixedly connected to clamping blocks, and the clamping blocks abut against the limit blocks.

[0009] As a preferred solution of the utility model, a plurality of heat dissipation holes are provided on the outer surfaces of the upper protective shell and the lower protective shell, and the upper protective shell and the lower protective shell abut against each other.

[0010] As a preferred solution of the utility model, the outer surface of the connecting rod is slidably connected to the inside of the slot.

[0011] As a preferred solution of the utility model, the outer surface of the connecting frame is slidably connected to the inside of the inner cavity, and the top end of the connecting frame abuts against the outer surface of the first absorbent cotton.

[0012] The beneficial effect of the utility model is that if water enters the shell, the water will be absorbed by the first absorbent cotton in the first time to prevent the water source from flowing into the interior of the upper protective shell and the lower protective shell. Secondly, the water source is blocked by the waterproof plate to further prevent water. If there is too much water, the second absorbent cotton will absorb water internally. The weight of the second absorbent cotton is borne by the connecting frame, and the force is applied by the spring to prevent water from flowing into the interior quickly, thereby improving the waterproof effect to a certain extent and avoiding water entering the inside of the power bank and causing rapid damage.
