Abstract
The present disclosure relates to the technical field of battery chargers, providing a battery charger. The charger comprises a lower cover assembly, an upper cover assembly, and a charging module. Space utilization is optimized through a circumferential array battery layout, where the battery negative terminal connects to the electrode plate via a contact spring, and the positive terminal forms a circuit with the circuit board through a metal contact. When the upper cover is closed, the compression spring is compressed to store energy and secure the battery; when the upper cover is opened, the spring releases its elastic force to drive the battery bracket, lifting the battery to a position where it can be easily removed.
Claims20
A battery charger, comprising:
- a housing, formed by an upper cover assembly and a lower cover assembly configured with an openable and closable connecting mechanism, wherein the lower cover assembly is provided with a battery compartment;
- and
- a charging module, comprising a multi-contact electrode assembly disposed in the lower cover assembly and a circuit control assembly disposed in the upper cover assembly, wherein the circuit control assembly is provided with a battery electrode connection terminal, and the multi-contact electrode assembly forms another battery electrode connection terminal through a contact spring;
- and
- a liftable battery carrier mechanism, comprising:
- a substrate axially displaceably installed in the battery compartment, carrying a battery and provided with a limit through-hole corresponding to the contact spring;
- and
- a push rod fixedly connected to a mounting substrate and having an axially extending chamber inside;
- and
- a resilient energy storage unit disposed in the chamber, with a bottom end thereof abutting the lower cover assembly;
- and
- wherein, in a case where the upper cover assembly is closed, the circuit control assembly abuts a top of the push rod and presses the push rod downward, causing the resilient energy storage unit to store energy, while driving the mounting substrate downward to allow the contact spring to pass through the limit through-hole, establishing a circuit for charging the battery;
- and
- in a case where the upper cover assembly is opened, the resilient energy storage unit releases an elastic force to drive the push rod upward, lifting the mounting substrate so that a top of the battery rises above a lowest opening plane of the lower cover assembly.
A battery charger, comprising:
- a housing, formed by an upper cover assembly and a lower cover assembly configured with an openable and closable connecting mechanism, wherein the lower cover assembly is provided with a battery compartment;
- and
- a charging module, comprising a first conductive assembly arranged on the lower cover assembly, comprising an elastically deflectable contact spring;
- and a second conductive assembly arranged in the upper cover assembly, having a connection node spatially corresponding to the contact spring;
- and
- a liftable battery carrier mechanism, comprising:
- a substrate axially displaceably installed in the battery compartment, carrying a battery and provided with a limit through-hole corresponding to the contact spring;
- and
- a push rod fixedly connected to the substrate;
- and
- a resilient energy storage unit coaxially arranged with the push rod, one end of which is fixedly connected to the push rod, and another end of which abuts against the lower cover assembly;
- wherein in a case where the upper cover assembly is closed, the upper cover assembly forms mechanical interference with a top end of the push rod, driving the push rod to axially displace and compress the resilient energy storage unit, while moving the substrate downward to allow the contact spring to pass through the limit through-hole, establishing a circuit for charging the battery;
- and
- in a case where the upper cover assembly is opened, the resilient energy storage unit drives the push rod to displace reversely and lifts the substrate, causing a top of the battery to be higher than a lowest opening plane of the lower cover assembly.
