In order to limit the travel of the cover plate 3 in the direction approaching the lower housing 114, in an embodiment, the housing 11 further includes a limiting member 15. The limiting member 15 is located in the accommodating cavity 111 of the housing 11, and specifically, the limiting member 15 is located on a side of the cover plate 3 away from the opening 112. The limiting member 15 is connected to the inner wall of the housing 11. Specifically, the limiting member 15 is connected to the inner wall of the housing 11 through the bracket 12. The limiting member 15 and the bracket 12 of the present embodiment are integrally formed, and of course, in other embodiments, the limiting member 15 and the bracket 12 may also be connected by clamping, bonding, or the like. The limiting member 15 of the present embodiment is a hollow cylindrical structure. The limiting piece 15 is coincident with the axis of the elastic piece 13, and the elastic piece 13 is installed in the limiting piece 15. The elastic member 13 abuts between the stopper 15 and the cover plate 3. In the initial state, a gap should be left between the cover plate 3 and the limiting member 15 to ensure that there is enough space when the cover plate 3 moves toward the lower housing 114.

When the cover plate 3 moves in a direction approaching the lower case 114, the upper surface of the stopper 15 contacts the lower surface of the cover plate 3, and the stopper 15 abuts against the cover plate 3. The stop member 15 prevents the cover plate 3 from moving further toward the lower housing 114. When the lower surface of the cover plate 3 contacts the upper surface of the stopper 15, the cover plate 3 moves to a stopper point in a direction approaching the lower case 114.

Specifically, the cover plate 3 is connected to the inner sidewall 1132 of the upper housing 113, and the cover plate 3 closes the inner sidewall 1132 toward the opening 112, which is the port of the cover plate 3. The contact of the Pogo-Pin connector 211 of the charging connector 21 is hidden in the escape through hole 31 of the cover plate 3. As shown in fig. 6, when the cover plate 3 moves toward the lower case 114 under pressure, and the stopper 15 abuts against the cover plate 3, the cover plate 3 stays at the stopper position, and the charging connector 21 is exposed from the cover plate 3, specifically, the contact of the Pogo-Pin connector 211 of the charging connector 21 is exposed from the escape through hole 31 of the cover plate 3.

In practical application, as shown in fig. 7 and 8, the product 200 to be charged is placed in the charging base 100 for charging. The bottom cover 201 of the product to be charged 200 is inserted into the upper case 113. The cover plate 3 moves downward under the pressure of the product 200 to be charged until the cover plate 3 abuts against the limiting member 15, and the cover plate 3 reaches the downward limiting point. At this time, the elastic member (not shown) is compressed, and at the same time, the contact of the Pogo-Pin connector 211 is exposed to the escape through hole 31 of the cover plate 3 and contacts the charging ring on the bottom cover 201 of the product to be charged 200. The charging dock 100 charges the product 200 to be charged. After charging, the product 200 to be charged is taken down, the elastic element resets, and the cover plate 3 resets to the initial uncharged state under the action of the elastic element. When the cover plate 3 is reset, the cover plate is lifted upwards, and the contact of the Pogo-Pin connector 211 is hidden in the avoiding through hole 31 in the cover plate 3.

When not needing to charge, the joint 2 that charges inserts dodging through-hole 31 of apron 3 or be located apron 3 under, and apron 3 protects the joint 2 that charges, avoids external and the joint 2 contact that charges, has removed the potential safety hazard because of the mistake touches and causes the short circuit of internal circuit. In addition, the charging connector 2 can be prevented from being damaged due to exposure, and the service life of the charging base is prolonged.
