Abstract

The invention relates to a portable mobile terminal comprising a casing, a sealing ring and a battery cover. The casing comprises a holding chamber for holding a battery, and a holding groove arranged surrounding the holding chamber. The sealing ring is arranged in the holding groove. The battery cover is connected to the casing for covering the holding chamber. The battery cover comprises a first cover and a second cover. The first cover comprises a body and a protruding rib arranged in a surrounding manner on the inner surface of the body. The protruding rib is embedded into the holding groove, and the sealing ring is tightly compressed. The first cover is tightly compressed by the second cover, and the covers are buckled in the casing. According to the portable mobile terminal providedby the invention, no screw hole is required to be arranged on the outer surface of the battery cover, and effects of water proofing and sealing can be achieved. With the portable mobile terminal, appearance of the battery cover outer surface is improved, the sealing ring is protected, and the service life of the sealing ring is prolonged. Therefore, the portable mobile terminal provides long-lasting sealing and water proofing effects.

Description

technical field [0001] The invention relates to a portable mobile terminal, in particular to a battery waterproof structure of the portable mobile terminal. Background technique [0002] The battery waterproof structure of the existing portable mobile terminal usually designs a groove on the back of the casing, accommodates the rubber sealing ring in the groove, and then fixes the battery cover through the screw hole on the back of the casing to compress the rubber sealing ring, so as to achieve The sealing and waterproof effect on the battery. However, this waterproof structure destroys the appearance of the battery cover and limits the shape of the battery cover. If the fixing screw is designed to the bottom of the case, it is necessary to add buckles on the battery cover and the case, install and remove the battery cover by sliding fit, and use the battery cover to press the rubber seal. However, this conventional design will inevitably cause a lot of friction to the so...
