[0017] Figure 4 yes Figure 2 A partial enlarged view of area B.

[0018] Among them: the shell upper cover 1, the upper snap-on portion 11, the first recessed portion 111, the first raised portion 112, the shell lower cover 2, the lower snap-on portion 21, the second raised portion 211, the second recessed portion 212, the shell side plate 3, the mounting portion 01 and the mounting hole 011. DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, a new type of protective power supply structure includes an upper shell cover 1, a lower shell cover 2 and a shell side plate 3; the upper shell cover 1, the lower shell cover 2 and the two shell side plates 3 form a closed cavity; the shell side plates 3 have openings, the power supply is arranged in the cavity, and leads extend from the shell side plates 3 on both sides respectively; the upper shell cover 1 and the lower shell cover 2 are sealed and buckled with each other; the shell side plates 3 are fixed to both sides of the upper shell cover 1 and the lower shell cover 2 by screws.

[0021] The upper and lower shell structures are adopted, and the upper and lower shells are tightly fixed together with a snap structure, which can avoid the gap caused by force during the subsequent power supply installation and application, affecting the overall waterproof function.

[0022] For further explanation, an upper buckle portion 11 is provided on the inner side of the bottom of the upper shell cover 1, and a lower buckle portion 21 is provided on the outer side of the top of the lower shell cover 2; the upper buckle portion 11 and the lower buckle portion 21 are buckled and sealed.

[0023] The upper cover 1 and the lower cover 2 of the shell are buckled and sealed by a mechanical structure, so that the upper cover 1 and the lower cover 2 of the shell are convenient to open and close.

[0024] To further explain, the upper snap-fit ​​portion 11 includes a first recessed portion 111 and a first protruding portion 112, wherein the first protruding portion 112 is arranged below the first recessed portion 111, and the first protruding portion 112 protrudes toward the inner side of the outer shell upper cover 1; the lower snap-fit ​​portion 21 includes a second protruding portion 211 and a second recessed portion 212, wherein the second protruding portion 211 is arranged above the second recessed portion 212, and the second protruding portion 211 protrudes toward the inner side of the outer shell lower cover 2; when the outer shell upper cover 1 and the outer shell lower cover 2 are closed, the first protruding portion 112 and the second recessed portion 212 cooperate with each other, and the second protruding portion 211 and the second recessed portion 212 cooperate with each other.

[0025] The first protrusion 112 and the second recess 212 are mutually buckled and matched, and the second protrusion 211 and the first recess 111 are mutually buckled and matched, so that there are two matching structures between the upper cover 1 and the lower cover 2, and the connection sealing is better. At the same time, when the second protrusion 211 of the lower cover 2 of the shell extends into the first recess 111 of the upper cover 1 of the shell, the glue can be filled as much as possible to effectively prevent water vapor from entering.

[0026] To further explain, the outer side surface of the second protrusion 211 is an inclined surface that slopes outward from top to bottom; the inner side surface of the first recessed portion 111 is an inclined surface that is adapted to the outer side surface of the second protrusion 211 .

[0027] When the second protrusion 211 is installed and matched with the first recessed portion 111 , the inclined surface plays a guiding role, making it easier for the housing upper cover 1 and the housing lower cover 2 to buckle together.

[0028] To further explain, both the upper shell cover 1 and the lower shell cover 2 are provided with a mounting portion 01; the mounting portion 01 is arranged on the outer side of the upper snap-on portion 11 and the outer bottom of the lower shell cover 2; a mounting hole 011 is opened in the center of the mounting portion 01, and screws pass through the mounting side plate and the mounting hole 011 to fix the mounting side plate.

[0029] The mounting portion 01 is arranged on the outer side of the upper cover 1 and the lower cover 2 of the shell. After the upper cover 1 and the lower cover 2 of the shell are closed, the mounting portion 01 for mounting the screws is on the outer side of the entire protective power supply structure. Therefore, the shell side cover can completely close both sides of the upper cover 1 and the lower cover 2 of the shell, thereby enhancing the protective effect.

[0030] For further explanation, the outer side of the mounting portion 01 is a curved side wall; and a strip-shaped notch is provided at the bottom of the mounting portion 01 .

[0031] After the screws are installed, the mounting portion 01 will not be damaged by the screws; at the same time, the outer side of the mounting portion 01 has no edges and corners and is not easily damaged.

[0032] For further explanation, the inner side surface of the housing upper cover 1 is a curved surface with the middle portion protruding downward.

[0033] During assembly, the waterproof rubber surface can be directly squeezed to squeeze the air inside the power supply to both sides, so that the potting glue is in close contact with the outer shell cover 1 to ensure the waterproof effect; and because the outer shell cover 1 adopts a curved surface design, the middle part of the cover is thicker, which further enhances the strength and prevents the outer shell cover 1 from being deformed due to the thermal expansion and contraction stress of the potting glue when the power supply is working.

[0034] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
