[0002] A mobile power source, also called a power charger, is a portable charging device that integrates power supply and charging functions by adopting high-frequency power technology and applying advanced intelligent dynamic adjustment charging technology. There are many types of power chargers and they are widely used in various fields, especially in the life field, and are widely used for common digital devices such as mobile phones, cameras, and tablet computers.

[0003] When a power charger is used to charge a mobile phone, due to its small size, it can be used with a data cable and is convenient to carry and can be used to charge the mobile phone anytime and anywhere where there is a socket. However, due to its convenience in carrying and small size, the use and placement of the charger are relatively random. In case of an accident, liquids such as water and beverages may spill onto the charger, or the liquid may drip on the side position of the charger, and splashing water may enter the data interface inside the charger, causing damage to the charger. When a power charger with a small size is used for a mobile phone, there is a problem that there is no waterproof design on its housing. Therefore, this application proposes a power charger housing with a waterproof structure. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a power charger housing with a waterproof structure, including a limiting component installed outside the power charger main body 1, including a limit frame 12 fixedly installed on the outside of one end of the power charger main body 1, an elastic strip 121 with one end connected to the side surface of the limit frame 12, and a sleeve frame 2 sleeved outside the limit frame 12. The limit frame 12 and the power charger main body 1 are combined by conventional methods. The split sleeve frame 2 is limited by the limit frame 12. A plug board 11 is installed on one side of the power charger main body 1. A protrusion 121a is provided on the end surface of the elastic strip 121 away from the limit frame 12. The protrusion 121a is embedded inside the rubber strip 311 to realize the limitation of the waterproof cover 31 and prevent the waterproof cover 31 from falling off. The elastic strip 121 made of metal material is squeezed by the waterproof cover 31. Under the action of elastic force, the elastic strip 121 is closely attached to the waterproof cover 31. Under the action of frictional force, the waterproof cover 31 is prevented from loosening;

[0026] A waterproof shell installed outside the power charger main body 1, including a waterproof cover 31, a connection cover 32 integrally injection-molded with one end of the waterproof cover 31, and a water blocking frame 33 integrally injection-molded with the connection cover 32. The waterproof cover 31, the connection cover 32 and the water blocking frame 33 are sleeved outside the power charger main body 1 to prevent spilled liquid from entering the data interface of the power charger main body 1. A water blocking gasket 321 is provided on the inner surface of the connection cover 32, and the water blocking gasket 321 plays a role in blocking splashing liquid. Rubber strips 311 are provided on the opposite outer surfaces of the waterproof cover 31, and the rubber strips 311 are attached to the elastic strips 121.

[0027] In this embodiment, a frame groove for cooperating with the limiting frame 12 is provided on the side surface of the hollow sleeve frame 2. A rectangular limiting groove communicating with the frame groove is provided on the side surface of the sleeve frame 2. The elastic strip 121 passes through the limiting groove. A rectangular pad groove for cooperating with the rubber strip 311 is provided on the outer surface of the waterproof cover 31. A groove 311a for cooperating with the protrusion 121a is provided on the rubber strip 311. The protrusion 121a is embedded in the groove 311a, so that the elastic strip 121 fits tightly, preventing the waterproof cover 31 from loosening.

[0028] In this embodiment, the waterproof cover 31, the connecting cover 32, and the water blocking frame 33 are all three-dimensional isosceles trapezoidal structures with a hollow interior and one end narrow and the other end wide. When liquid falls on the surfaces of the waterproof cover 31, the connecting cover 32, and the water blocking frame 33, the liquid flows on the sloping surfaces of the waterproof cover 31, the connecting cover 32, and the water blocking frame 33, preventing the liquid from adhering. The narrow-diameter end of the connecting cover 32 and the narrow-diameter end of the water blocking frame 33 are combined to form a water accumulation area b. When liquid falls on the water accumulation area b, it prevents the flowing-down liquid from flowing towards the power charger main body 1.

[0029] In this embodiment, a data cable jack is provided on the side surface of the power charger main body 1 away from the plug board 11. The inclined water blocking gasket 321 is opposite to the data cable jack. The water blocking gasket 321 blocks the data cable jack, preventing splashing liquid from entering the data cable jack and achieving a waterproof effect.

[0030] In summary: There is a waterproof design on the power charger housing. The waterproof cover 31, the connecting cover 32, and the water blocking frame 33 are sleeved outside the power charger main body 1. When liquid falls on the surfaces of the waterproof cover 31, the connecting cover 32, and the water blocking frame 33, the liquid flows on the sloping surfaces of the waterproof cover 31, the connecting cover 32, and the water blocking frame 33. The water blocking gasket 321 blocks the data cable jack, preventing splashing liquid from entering the data cable jack, and has a waterproof effect.

[0031] Embodiment 2

[0032] Please refer to Figures 1 to 5, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. In order to enhance the effect of protecting the plug board 11, a split protective plate 4 is provided at one end of the power charger main body 1. A protective sleeve 41 is provided on one side surface of the protective plate 4, and plug posts 42 are provided at the corner positions on the other side surface. The plug posts 42 are inserted into the inside of the limit frame 12, and the plug board 11 is inserted into the protective plate 4 and the protective sleeve 41, so that the plug board 11 is protected and liquid adhesion to the plug board 11 is avoided. A magnet block 421 is provided at the center position of the surface at one end of the plug post 42. A circular groove 122 matching the plug post 42 is formed on the surface at the corner position of the limit frame 12. A metal circular sheet 123 is provided inside the limit frame 12 at the circular groove 122. The magnet block 421 is magnetically adsorbed and connected to the metal circular sheet 123. Rectangular holes for inserting the plug board 11 are provided on the protective plate 4 and the protective sleeve 41. The magnet block 421 on the plug post 42 is stably adsorbed to the metal circular sheet 123.

[0033] In summary: The protective plate 4 is attached to the limit frame 12 and the sleeve frame 2. The magnet block 421 on the plug post 42 is stably adsorbed to the metal circular sheet 123. The plug board 11 is inserted into the protective plate 4 and the protective sleeve 41, so that the plug board 11 is protected and liquid adhesion to the plug board 11 is avoided.
