Referring to fig. 3, in some embodiments, the charger further comprises: a first elastic member 5, the first elastic member 5 being located between the first end of the lever 4 and the housing 2; for example, the first elastic member 5 may be a leaf spring.

One end of the first elastic piece 5 is fixed on the shell 2, and the other end of the first elastic piece 5 is propped against the first end of the lever 4;

under the condition that the charged equipment is placed on the shell 1 and the second charging terminal of the charged equipment is opposite to the second opening hole 102, the first elastic piece 5 is in an elastic deformation state;

in a case where the device to be charged is not placed on the housing 1, the first elastic member 5 is in a natural state.

In the present embodiment, the first elastic member 5 is used to apply an elastic force to the first end of the lever 4, thereby pushing the movable block 2 to rise to protrude out of the housing 1. Specifically, when the charger is in the non-operating state, the first elastic member 5 is in a compressed state or a natural state, so if the movable block 2 receives an external force or a collision in the non-operating scene, the first elastic member 5 can provide a holding force for the movable block 2 to keep extending out of the housing 1, thereby effectively protecting the first charging terminal 3.

It can be understood that when the charger is in the working state, the watch body of the charged device can press the movable block 2 into the housing 1 against the elastic force of the first elastic member 5 due to the need to place the charged device on the charger.

in the case where the device to be charged is not placed on the housing 1, the second elastic member 6 is in a natural state.

In the embodiment of the present application, the second elastic member 6 is used to apply an elastic force to the first charging terminal 3, thereby pushing the first charging terminal 3 to descend to retract into the housing 1. Specifically, when the charger is in a non-working state, the second elastic member 6 is in a compressed state or a natural state, so that if the first charging terminal 3 moves outwards due to vibration or collision in a non-working scene, the first charging terminal 3 can still be retracted into the housing 1 under the action of the second elastic member 6, and the first charging terminal 3 is effectively protected.

It can be understood that, when the charger is in the working state, as the meter body of the charged device presses the movable block 2 into the housing 1, the pressure is transmitted through the lever 4, the first charging terminal 3 is pushed out of the housing 1 against the elastic force of the second elastic member 6, and is inserted into the charged device for charging.

It should be noted that the power supply may be a power supply inside the charger, that is, the charger may be designed to be charged by a built-in power supply without an external power supply; alternatively, the power source may be a power source external to the charger, i.e., the charger may be designed to require an external power source for charging.

Referring to fig. 3, in some embodiments, the charger further comprises: a Flexible Printed Circuit (FPC) 8;

the first charging terminal 3 is electrically connected to the PCB 7 through the FPC 8.

In the embodiment of the present application, considering that the first charging terminal 3 needs to be moved, the FPC8 is added to electrically connect the first charging terminal 3 and the PCB 7, so that the PCB 7 can be directly fixed inside the charger, and the internal structure is simplified.

Further, the length of the FPC8 is larger than the distance between the first charging terminal 3 and the PCB 7.

In the embodiment of the present application, the FPC8 has a redundant length, so that it is ensured that the PCB 7 is not dragged in the process of moving the first charging terminal 3 up and down, thereby playing a role in protecting a device.

Referring to fig. 4 and 5, in some embodiments, the charger further comprises: a charging wire 9;

one end of the charging wire 9 extends into the accommodating cavity and is electrically connected with the PCB 7.
