Embodiments of the present invention will now be described with reference to the accompanying drawings, in which like reference numerals represent like elements. The concealable charging connector 100 provided by the present invention is mainly applicable to the electronic device 1 using wireless charging or contact charging, but is not limited thereto.

First, as shown in FIGS. 1-5 , the concealable charging connector 100 provided by the present invention includes a mounting seat 110 , a pin shaft assembly 120 and an electrical connection assembly 130 . The mounting seat 110 is used for connecting to the mounting position, and the mounting seat 110 is provided with a stepped and parallel first support surface 111 and a second support surface 112 and are connected to the first support surface 111 and the second support surface. The driving surface 113 between the 112 and the driving surface 113 extends obliquely upward from the first supporting surface 111 to the second supporting surface 112 . One end of the electrical connection component 130 is disposed on the second support surface 112 , and the other end thereof is used for electrical connection with the main circuit board of the electronic device. The needle shaft assembly 120 includes a base 121 slidably connected to the mounting seat 110 and at least one needle shaft 122 telescopically installed on the base 121. The telescopic direction of the needle shaft 122 intersects with the sliding direction of the base 121. The shafts 122 have opposite first ends 1221 and second ends 1222. When the base 121 slides along the mounting seat 110, the first end 1221 of the needle shaft 122 can be detachably abutted against the first support surface 111 or the electrical connection assembly 130. , the second end 1222 of the needle shaft 122 protrudes telescopically out of the base 121 for electrical connection with the charging end. Therefore, the needle shaft 122 can be selectively protruded out of the base 121 through the sliding of the base 121, and when not in use, the needle shaft 122 is accommodated in the base 121 to reduce the probability of damage to it.

Continuing to refer to FIGS. 1-5 and 8, the mounting seat 110 has a body with a long strip structure, the bottom surface of the body is a plane, and the upper surface of the body is sequentially provided with first support surfaces 111 along its longitudinal direction. , the driving surface 113, the second supporting surface 112, the first supporting surface 111, the second supporting surface 112 are planes parallel to each other, the driving surface 113 is an inclined surface, and the height from the second supporting surface 112 to the bottom surface of the body is greater than the first supporting surface 111 to the height of the bottom surface of the body. Therefore, when the base 121 is located above the first support surface 111 , the first end 1221 of the needle shaft 122 protrudes from the lower end of the base 121 , and the second end 1222 of the needle shaft 122 is received into the base 121 , and the base 121 faces toward the base 121 . During the sliding process of the second supporting surface 112, when the needle shaft 122 is in contact with the driving surface 113, the driving surface 113 will push the needle shaft 122 to protrude above the base 121. When the base 121 slides to the second When the support surface 112 is above, the first end 1221 of the needle shaft 122 abuts against the electrical connection component 130 of the second support surface 112 to achieve conduction, and the pushing action of the second support surface 112 makes the second end 1222 of the needle shaft 122 Keep protruding from the upper end of the base 121 to be electrically connected to the charging terminal. At this time, the concealable charging connector 100 can be used for charging.

It is understandable that the driving surface 113 is not limited to an inclined surface, for example, it can also be provided as an arc surface, etc., and the same can achieve a pushing action on the needle shaft 122 .

One end 1221 remains protruding out of the base 121, and the second end 1222 of the needle shaft 122 is received into the base 121. When the base 121 slides to the top of the second supporting surface 112, the electrical The connecting element 130 abuts against the first end 1221 of the needle shaft 122 so that the second end 1222 protrudes out of the base 121 . At this time, the elastic member 124 is compressed and deformed. Afterwards, the elastic member 124 restores the deformation and drives the needle shaft 122 to reset, that is, the first end 1221 of the needle shaft 122 protrudes out of the base 121 again, and the second end 1222 is retracted into the base 121 again. Therefore, the above The elastic member 124 makes the first end 1221 of the needle shaft 122 always have a tendency to protrude out of the base 121 , and also makes the second end 1222 of the needle shaft 122 always have a tendency to be received into the base 121 .
