Embodiment Construction

[0014] The invention discloses a locking structure of a battery cover, which is suitable for portable electronic devices such as mobile phones.

[0015] see figure 1 , the battery cover locking structure 100 includes a battery cover 10, a housing 20, a magnetic element 30 provided on the battery cover 10, an iron core 40 provided on the housing 20, and an iron core 40 provided on the iron core Coil 50 on 40. ginseng Image 6 , the battery cover 10 and the casing 20 are locked together by the attractive force between the magnetic element 30 and the iron core 40 . The coil 50 is electrically connected to an internal circuit (not shown) of the battery cover locking structure 100 . When the coil 50 is energized, the coil 50 generates a magnetic field opposite to the magnetic pole of the magnetic element 30 , thereby generating a repulsive force between the iron core 40 and the magnetic element 30 . In this way, the engagement between the battery cover 10 and the casing 20 is r...

Description

technical field [0001] The invention relates to a locking structure of a battery cover, in particular to a locking structure of a battery cover applied to portable electronic devices such as mobile phones. Background technique [0002] Mobile phones and personal digital assistants (Personal Digital Assistant, PDA) and other portable electronic devices are increasingly widely used, and the batteries that provide energy for portable electronic devices have to be replaced due to energy consumption. In order to make the battery easy to install, people have designed Many battery cover snap-lock structures. [0003] The existing locking structure of the battery cover of the portable electronic device generally includes a groove opened on the casing of the portable electronic device and a battery cover capable of covering the groove. After the battery is installed in the groove, the battery cover is fastened on the casing to limit the battery in the groove. In order to fix the ba...
