When the reel 3 rotates, the first housing 1 is driven to be far away from or close to the second housing 2, the NFC antenna 18 located on the first housing 1 moves along with the first housing 1, so that the NFC antenna 18 and the main board 13 move, and at this time, when the contact points on the NFC antenna 18 are in contact electrical connection with different contact points on the main board 13, the electronic device can realize an NFC function in the process of completely unfolding, completely contracting, unfolding to completely unfolding, and contracting to completely contracting of the flexible screen 4.
As shown in fig. 2 to 4, a first contact 5 is disposed on the NFC antenna 18, a second contact 6 and a third contact 7 are disposed on the main board 13, and when the flexible screen 4 is completely wound on the reel 3, the flexible screen 4 is completely contracted, and the first contact 5 is in contact with and electrically connected to the second contact 6; when the flexible screen 4 is completely unfolded, the first contact 5 is in contact with and electrically connected to the third contact 7, it should be noted that when the flexible screen 4 is completely unfolded, the flexible screen 4 is unfolded to the maximum area, and when the flexible screen 4 is completely contracted, the unfolded area of the flexible screen 4 is 0.
As a preferred embodiment, as shown in fig. 5, a first protrusion 8 is disposed on the first contact 5, a second protrusion is disposed on the second contact 6, a third protrusion is disposed on the third contact 7, the first protrusion 8 is a hard structural body, the second protrusion includes a first elastic sheet 9 and a first spring 10, the third protrusion includes a second elastic sheet 11 and a second spring 12, a bottom end of the first elastic sheet 9 is electrically connected to the main board 13, a bottom end of the first spring 10 is fixedly connected to the main board 13, and a top end of the first spring 10 is fixedly connected to a top end of the first elastic sheet 9; the bottom end of the second elastic sheet 11 is electrically connected with the main board 13, the bottom end of the second spring 12 is fixedly connected with the main board 13, and the top end of the second spring 12 is fixedly connected with the top end of the second elastic sheet 11; the first elastic sheet 9 and the second elastic sheet 11 are arranged oppositely, and the first elastic sheet 9 and the second elastic sheet 11 are both in a straight structure; when the flexible screen 4 is completely wound on the reel 3, the first protrusion 8 is abutted against the first elastic sheet 9; when the flexible screen 4 is completely unfolded, the first protrusion 8 abuts against the second elastic sheet 11.
When the first protrusion 8 abuts against the first elastic sheet 9 and the second elastic sheet 11, the first spring 10 and the second spring 12 will be compressed, at this time, the first elastic sheet 9 will receive the acting force of the deformation of the first spring 10 and the pressure of the first protrusion 8, and the second elastic sheet 11 will receive the acting force of the deformation of the second spring 12 and the pressure of the first protrusion 8, so that the first elastic sheet 9 is kept stable under the combined action of the first protrusion 8 and the first spring 10, and the second elastic sheet 11 is kept stable under the combined action of the first protrusion 8 and the second spring 12, thereby improving the stability and reliability when the first elastic sheet 9 and the second elastic sheet 11 abut against the first protrusion 8. Moreover, since the first elastic piece 9 and the second elastic piece 11 are disposed opposite to each other, the first spring 10 and the second spring 12 respectively provide an acting force opposite to the moving direction of the NFC antenna 18 to the first elastic piece 9 and the second elastic piece 11, so that the first contact 5 can be prevented from sliding out of the area between the second contact 6 and the third contact 7.
Preferably, in order to further improve the reliability of the first protrusion 8 when abutting against the first elastic sheet 9 and the second elastic sheet 11, the first protrusion 8 is provided with a tip, and when the flexible screen 4 is completely wound on the reel 3, the tip abuts against the first elastic sheet 9; when the flexible screen 4 is completely unfolded, the tip abuts against the second elastic sheet 11, so that the reliability of the electrical connection between the first protrusion 8 and the first elastic sheet 9 and the second elastic sheet 11 can be further improved through the tip.

The present embodiment is different from the first embodiment only in that: as shown in fig. 6, at least one fourth contact 14 in contact electrical connection with the first contact 5 is disposed between the second contact 6 and the third contact 7, so that when the electronic device is retracted to be fully retracted or extended to be fully extended, the first contact 5 can be in contact electrical connection with a different fourth contact 14, so that the electronic device can implement an NFC function during both the process of being retracted to be fully retracted and the process of being extended to be fully extended.
Preferably, at least one of the fourth contacts 14 is uniformly spaced between the second contact 6 and the third contact 7, so that a user can control the electronic device to implement an NFC function under different retraction or expansion degrees during the process of retracting the electronic device to the fully retracted state or expanding the electronic device to the fully expanded state.
As shown in fig. 5, a fourth protrusion is disposed on the fourth contact 14, the fourth protrusion includes an arc-shaped third elastic sheet 15 and a straight-line-shaped third spring 16, both ends of the third elastic sheet 15 are electrically connected to the main board 13, the bottom end of the third spring 16 is fixedly connected to the main board 13, the top end of the third spring 16 is fixedly connected to the third elastic sheet 15, and when the first contact 5 is electrically connected to the fourth contact 14 in a contacting manner, the first protrusion 8 abuts against the third elastic sheet 15.
Because the two ends of the third spring 16 are respectively connected with the main board 13 and the third elastic sheet 15, when the first protrusion 8 abuts against the third elastic sheet 15, the third spring 16 will be compressed, and at this time, the third elastic sheet 15 will receive the deformation acting force of the third spring 16, so that the first protrusion 8 is in close contact with the third elastic sheet 15, and the stability and reliability of the first protrusion 8 abutting against the third elastic sheet 15 are improved. Moreover, since the third elastic sheet 15 is arc-shaped, when the first housing 1 and the second housing 2 slide relatively, the first protrusion 8 and the third elastic sheet 15 will be staggered, so as to avoid the interference of the fourth protrusion on the relative sliding of the first housing 1 and the second housing 2.
EXAMPLE III
The present embodiment is different from the first embodiment only in that: a contact strip 17 in contact and electrical connection with the first contact 5 is arranged between the second contact 6 and the third contact 7, and two ends of the contact strip 17 are respectively in electrical connection with the second contact 6 and the third contact 7, so that the NFC function can be realized at any position of the electronic device in the process of being retracted to be fully retracted or in the process of being expanded to be fully expanded through the contact strip 17.
