The charging induction terminal 500 is used for charging an external electronic product to be charged. Specifically, in the present embodiment, the charging sensing terminal 500 includes the sensing module 300. The charging sensing terminal 500 is a conventional terminal, and therefore, is not described in detail herein. When a user needs to charge an external electronic product to be charged by using the charging induction terminal 500, the user presses the Z-shaped pressing plate 410 to separate the clamping block 411 from the limiting clamping slot 501, and the charging induction terminal 500 separates from the accommodating slot 401 due to the action of gravity and rotates around the fixing frame 400. And charging the external electronic product to be charged at a proper position.

In order to facilitate the user to press the Z-shaped pressing plate 410, please refer to fig. 4 to 5, in one embodiment, an anti-slip layer 412 is disposed on an end of the Z-shaped pressing plate 410 away from the charging sensing terminal 500. In this embodiment, the anti-slip layer 412 is an anti-slip rubber pad. The anti-skid rubber pad has good elasticity, excellent toughness and wear resistance. On one hand, the friction force between the finger and the Z-shaped pressing plate 410 is increased, thereby increasing the operational stability of the Z-shaped pressing plate 410. On the other hand, the antiskid rubber pad is softer, protects the fingers from being scratched, and increases the service life of the Z-shaped pressing plate 410. Further, the anti-slip rubber pad is provided with anti-slip lines to further increase the friction force between the fingers and the Z-shaped pressing plate 410 and increase the working stability of the Z-shaped pressing plate 410. As such, the anti-slip layer 412 disposed at an end of the Z-shaped pressing plate 410 away from the charging sensing terminal 500 facilitates the user to press the Z-shaped pressing plate 410.

In order to facilitate the user to snap the charging sensing terminal 500 into the receiving slot 401, in one embodiment, a sliding curved surface 520 is disposed on a surface of the charging sensing terminal 500 away from the rotating rod 510 and close to the fixing frame 400. When the user buckles the charging induction terminal 500 into the receiving slot 401, the blocking block 411 moves along the sliding curved surface 520 relative to the charging induction terminal 500 and falls into the limiting blocking slot 501 to be blocked with the charging induction terminal 500. Avoid charging inductive terminal 500 and the hard contact of screens piece 411, will charge inductive terminal 500 fish tail. Further, the cross section of the blocking block 411 is trapezoidal. That is, when the user fastens the charging inductive terminal 500 into the receiving slot 401, the inclined surface of the engaging block 411 moves along the sliding curved surface 520 relative to the charging inductive terminal 500, and falls into the limiting engaging slot 501 to engage with the charging inductive terminal 500. Avoid the edges and corners of screens piece 411 and the hard contact of screens piece 411, will charge the induction terminal 500 fish tail. Therefore, the charging induction terminal 500 can be conveniently buckled into the accommodating groove 401, and the clamping block 411 can be prevented from scratching the charging induction terminal 500.

When the user presses the Z-shaped pressing plate 410, in order to eject the charging sensing terminal 500 from the receiving slot 401, in one embodiment, the fixing frame 400 is further provided with two Z-shaped resilient pieces 420, and a bent portion of each Z-shaped resilient piece 420 abuts against one end of the rotating rod 510. When the user squeezes the Z-shaped pressing plate 410, the blocking block 411 is separated from the position-limiting slot 501, and due to the elastic force of the two Z-shaped elastic pieces 420, the charging induction terminal 500 is elastically ejected out of the accommodating slot 401, so that the position of the position-limiting slot 501 on the charging induction terminal 500 is not aligned with the blocking block 411. Thus, the clamping block 411 is prevented from reentering the limiting clamping groove 501 when the user releases the Z-shaped pressing plate 410, and the charging induction terminal 500 is limited in the accommodating groove 401.

When the user presses the Z-shaped pressing plate 410, in order to further eject the charge sensing terminal 500 from the receiving groove 401, in one embodiment, an elastic pad is disposed at the bottom of the receiving groove 401. When the charging induction terminal 500 is in the accommodating groove 401, the clamping block 411 is inserted into the limiting clamping groove 501 and clamped with the charging induction terminal 500, the charging induction terminal 500 extrudes the elastic pad, and the elastic pad is compressed to generate elastic deformation. In this embodiment, the elastic pad is an elastic rubber pad. In another embodiment, the resilient pad is a foam pad. In this way, when the user presses the Z-shaped pressing plate 410, the blocking block 411 is separated from the limiting slot 501, and the elastic pad is deformed to be restored, so that the charging sensing terminal 500 is ejected from the receiving slot 401. Thus, the blocking block 411 is prevented from reentering the limiting clamping groove 501 and limiting the charging induction terminal 500 in the accommodating groove 401 when the user releases the Z-shaped pressing plate 410.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
