Description

Technical Field

[0001] This utility model relates to the field of waterproof power supplies, and more particularly to a waterproof device for outdoor power supplies. Background Technology

[0002] Outdoor power supplies, also known as portable energy storage power supplies, are portable energy storage devices with built-in battery packs that can store electrical energy and provide various types of power output. They can meet users' power needs when there is a lack of power outdoors. Since they are generally used outdoors, they are easily affected by rain or other sources of moisture, so outdoor power supplies need to have strong waterproof performance.

[0003] The waterproofing of existing outdoor power supplies mainly focuses on the waterproofing of the socket holes. The most common waterproofing method is to use socket plugs or sleeves made of silicone rubber or similar materials. When not charging, the socket holes are blocked by the plugs or sleeves to prevent moisture from contaminating them. However, the plugs or sleeves need to be removed when charging, which is not convenient for protecting the socket during charging. Moisture can easily contaminate the power socket during charging, and rainwater can easily penetrate the dustproof mesh and enter the ventilation openings, contaminating the internal components. As a result, the waterproofing performance of the power supply is poor during charging and rainy weather. Utility Model Content

[0004] To overcome the shortcomings of existing outdoor power supply waterproofing methods, such as the inconvenience of protecting the socket during charging, the easy contamination of the power socket by moisture during charging, and the easy penetration of rainwater into the dustproof mesh, resulting in poor waterproofing performance of the power supply during charging and in rainy weather, this utility model provides a waterproofing device for outdoor power supplies that facilitates socket protection during charging, reduces the possibility of moisture contamination of the power socket during charging, reduces the possibility of rainwater penetrating the dustproof mesh, and improves the waterproofing performance of the power supply during charging and in rainy weather.

[0005] Technical solution: A waterproof device for an outdoor power supply, comprising a protective shell;

[0006] A socket fixed to the protective housing;

[0007] Two dustproof nets are fixed to the protective shell;

[0008] Top cover fixed to the top of the protective shell;

[0009] Water-blocking mechanism installed on the protective shell;

[0010] The sealing mechanism is installed on the protective shell and the water-blocking mechanism.

[0011] Furthermore, it is particularly preferred that the water-blocking mechanism includes a waterproof cover fixed to the protective shell, the waterproof cover covering the socket, a notch at the bottom of the waterproof cover, two hinges on the upper part of the waterproof cover, a sealing plate fixed between the rotating pages of the two hinges, and two buckles on the lower part of the waterproof cover, the female buckles of the two buckles being fixed to the sealing plate.

[0012] Furthermore, it is particularly preferred that the sealing mechanism includes a sealing airbag fixed to the notch of the waterproof cover, an air pump fixed to the inner wall of the protective shell, a hose fixed to the air pump nozzle, the other end of the hose being fixed to the sealing airbag, and the air pump communicating with the sealing airbag through the hose.

[0013] Furthermore, it is particularly preferred that the device also includes a rain-proof mechanism disposed on the protective shell. The rain-proof mechanism includes two mounting brackets fixed to the protective shell, each mounting bracket covering two dustproof nets, several grid plates rotatably connected to the mounting brackets, a worm wheel fixed to one side of the grid plate, and a worm rotatably connected to the mounting brackets. The worm and several worm wheels on the same side of the worm are all engaged.

[0014] In addition, it is particularly preferred that the device also includes a rubber ring fixed to the sealing plate.

[0015] The beneficial effects of this utility model are as follows: 1. When the user straightens the charging cable and places it in the notch of the waterproof cover, then presses the sealing plate down until it contacts the waterproof cover, and fastens the two buckles to make the sealing plate and the waterproof cover fit tightly again, the air pump inflates the sealing airbag through the hose. The inflated sealing airbag blocks the gap between the notch of the waterproof cover and the sealing plate, which can facilitate the protection of the socket during charging, reduce the possibility of water contamination of the power socket during charging, and improve the waterproof performance of the power supply during charging.

[0016] 2. By using the user to rotate the worm gear, the rotation of the worm gear drives several worm wheels on the same side to rotate. The rotation of the worm wheels causes the grid plate to rotate downward. The downward rotation of the grid plate greatly reduces the gaps between the grid plates, reducing the possibility of rainwater entering the dustproof net and improving the waterproof performance of the power supply in rainy weather.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0023] Example 1: A waterproof device for an outdoor power supply, such as Figures 1-3 As shown, it includes a protective shell 1;

[0024] The socket 2 is fixed to the protective housing 1;

[0025] Two dustproof nets 3 are fixed to the protective shell 1, and the two dustproof nets 3 are located at the ventilation openings on both sides of the protective shell 1;

[0026] The top cover 4 is bolted to the top of the protective shell 1;

[0027] A water-blocking mechanism is provided on the protective shell 1 to prevent water from contacting the socket 2;

[0028] The sealing mechanism is provided on the protective shell 1 and the water-blocking mechanism to increase the airtightness between the charging cable and the water-blocking mechanism.

[0029] The water-blocking mechanism includes a waterproof cover 5 fixed to the protective shell 1, the waterproof cover 5 covering the socket 2, the lower part of the waterproof cover 5 having a notch, two hinges 6 set on the upper part of the waterproof cover 5, the two hinges 6 being symmetrically arranged, a sealing plate 7 fixed between the rotating pages of the two hinges 6, and two buckles 8 set on the lower part of the waterproof cover 5, the two buckles 8 being symmetrically arranged, the female buckles of the two buckles 8 being fixedly connected to the sealing plate 7.

[0030] The sealing mechanism includes a sealing airbag 9 fixed to the notch of the waterproof cover 5, an air pump 10 connected to the inner wall of the protective shell 1 by bolts, a hose 11 fixed to the air nozzle of the air pump 10, the other end of the hose 11 being fixed to the sealing airbag 9, and the air pump 10 communicating with the sealing airbag 9 through the hose 11.

[0031] Initially, the sealing plate 7 is tightly fitted to the waterproof cover 5 via the fasteners 8. The airbag is filled with gas and inflated, blocking the gap between the waterproof cover 5 and the sealing plate 7. When charging is needed, the user loosens the two fasteners 8, controls the air pump 10 to extract the gas from the sealing airbag 9, causing the airbag to deflate. Then, the sealing plate 7 is lifted upwards to expose the socket 2. After plugging in the plug, the user straightens the charging cable and positions it within the gap in the waterproof cover 5. The sealing plate 7 is then pressed downwards until it contacts the waterproof cover 5. Finally, the user fastens the two fasteners 8 to ensure a tight fit between the sealing plate 7 and the waterproof cover 5. The user starts the air pump 10, which inflates the sealing airbag 9 through the hose 11. The sealing airbag 9 inflates and clamps the charging cable, blocking the gap between the waterproof cover 5 and the sealing plate 7. This operation helps protect the socket 2 during charging, reducing the possibility of moisture contamination of the power socket and improving the waterproof performance of the power supply. After charging is complete, the user loosens the two buckles 8, lifts the sealing plate 7 slightly upward, unplugs the plug, presses the sealing plate 7 down until it contacts the waterproof cover 5, and then fastens the two buckles 8 again to make the sealing plate 7 and the waterproof cover 5 fit tightly again for continued waterproofing.

[0032] Example 2: Based on Example 1, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes a rain-proof mechanism disposed on the protective shell 1. The rain-proof mechanism is used to prevent rainwater from entering the protective shell 1 through the dustproof net 3. The rain-proof mechanism includes two mounting brackets 12 fixed to the protective shell 1, the two mounting brackets 12 respectively covering two dustproof nets 3, several grid plates 13 rotatably connected to the mounting brackets 12, the several grid plates 13 on the same mounting bracket 12 are evenly spaced, a worm wheel 14 fixed to one side of the grid plate 13, and a worm 15 rotatably connected to the mounting bracket 12. The worm 15 and the several worm wheels 14 on the same side are all meshed. The worm 15 drives the worm wheels 14 to rotate, thereby driving the grid plate 13 to rotate to adjust its angle.

[0033] It also includes a rubber ring 16 fixed to the sealing plate 7, which is used to make the waterproof cover 5 and the sealing plate 7 fit more tightly.

[0034] Initially, the worm gear 15 and worm wheel 14 are stationary due to the meshing of their threads and teeth. At this time, the gaps between the grid plates 13 are relatively large, ensuring that the power supply can dissipate heat normally. After rain, the user rotates the worm gear 15, which drives several worm wheels 14 on the same side to rotate. The rotation of the worm wheels 14 causes the grid plates 13 to rotate downwards. The downward rotation of the grid plates 13 greatly reduces the gaps between them, reducing the possibility of rainwater entering the dustproof net 3 and improving the waterproof performance of the power supply in rainy weather. When it stops raining, the user rotates the worm gear 15 in the opposite direction, which drives several worm wheels 14 on the same side to rotate in the opposite direction. The reverse rotation of the worm wheels 14 causes the grid plates 13 to rotate upwards. When the gaps between the grid plates 13 return to their initial normal state, the operator stops rotating the worm gear 15.

[0035] The rubber ring 16 can increase the airtightness between the waterproof cover 5 and the sealing plate 7, thereby improving the waterproof performance.

[0036] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
