Description

Technical Field

[0001] The utility model relates to the technical field of shared power banks, in particular to a waterproof charging cabinet. Background Art

[0002] A shared power bank refers to a charging rental device provided by an enterprise. Users can rent a power bank by scanning the QR code on the device screen with a mobile device and paying a deposit. After the power bank is successfully returned, the deposit can be withdrawn at any time and refunded to the account. When not lent out, the shared power bank is stored in a shared power bank cabinet. The shared power bank cabinet is used to store the shared power bank and charge the shared power bank. The sharing economy has brought great convenience to the travel life of the people.

[0003] The existing shared power bank cabinets have poor waterproof performance and are generally placed indoors. Outdoors, such as in outdoor tourist attractions, it is not easy to place the existing shared power bank cabinets. However, in the existing market environment, due to application requirements, shared power banks need to adapt to outdoor weather to meet the usage needs of users. In rainy weather, the airflow in the environment will cause the rain to deflect and fall onto the power bank cabinet. When the power bank cabinet is in the power-on state, with the invasion of rain, short circuits, wear and other phenomena are likely to occur. The high-voltage part of the internal power supply is exposed. If the power supply module is flooded, there is a risk of burning out the power supply and electric leakage, seriously affecting the normal use and service life of the power bank cabinet. Summary of the Invention

[0004] The utility model provides a waterproof charging cabinet, which solves the technical problems that the existing power bank cabinets have poor waterproof performance and cannot adapt to outdoor application scenarios, resulting in few application scenarios.

[0005] To solve the above technical problems, the utility model provides a waterproof charging cabinet, which includes an upper cabinet body, at least one middle cabinet body and a bottom shell, as well as a fixing bracket. The upper cabinet body / the middle cabinet body and the middle cabinet body are fixedly connected through the fixing bracket, and the lower part of the bottom middle cabinet body is fixedly connected with the bottom shell; the inside of the upper cabinet body is hollow to form a first cavity, and a power supply module is installed inside the first cavity; the inside of the middle cabinet body is hollow to form a second cavity, and a charging inner container is installed inside the second cavity; the first cavity is communicated with the second cavity.

[0006] Based on the outdoor power demand, this basic solution designs a waterproof power bank charging cabinet, with the power module placed in the first cavity on the top layer, preventing rainwater from infiltrating into the power module, effectively preventing high-voltage electricity leakage caused by water immersion during heavy rain weather, and solving the safety hazard of high-voltage leakage. At the same time, a fixed bracket is set up to connect the upper cabinet / middle cabinet and the middle cabinet, making the first cavity communicate with the second cavity. Thus, while realizing a modular assembly structure (setting the number of middle cabinets as needed to increase or decrease the number of shared power banks), it avoids water accumulation inside each layer and reduces the material manufacturing cost at the same time.

[0007] In a further implementation, the fixed bracket is an annular bracket, which is sequentially provided with a nested structure, a positioning member, an installation structure, and a slot structure from the outer edge inward; the middle part of the nested structure is a horizontal part, the middle of the top surface of the horizontal part is provided with a convex strip protruding upward, and the inner side of the horizontal part is bent downward to form a vertical part; the outer side of the convex strip and the top surface of the horizontal part form a waterproof table that is recessed inward, and the waterproof table is nested and installed with the upper cabinet; the outer side of the vertical part and the top surface of the horizontal part form a fitting groove that is recessed inward, and the fitting groove is nested and installed with the middle cabinet.

[0008] This solution sets a nested structure on the outside of the fixed bracket.

[0011] The second fixing member is an installation bolt, the lower part of which has an opening and extends downward to be nested with the middle cabinet, and a screw passes through the middle cabinet and is screwed with the second fixing member.

[0012] Based on the functional positioning of the intermediate connector, this solution sets a first fixing member that protrudes upward and a second fixing member that protrudes downward on the fixing plate. While performing nested positioning, screw assembly is carried out, with stable structure, high assembly flexibility and low operation difficulty.
