Referring to fig. 2, fig. 2 is a partially enlarged view of a portion a in fig. 1. The housing 11 is further provided with a receiving groove 111, a locking groove 112 and a first metal protrusion 113.

The accommodating groove 111 is defined by a side wall 1111 and a bottom wall 1112, and a notch of the accommodating groove 111 is opened in a side surface of the housing 11 so that the accommodating groove 111 communicates with the outside of the housing 11. The notch of the card slot 112 is opened on the bottom wall 1112 forming the receiving groove 111 so that the card slot 112 communicates with the receiving groove 111.

In the embodiment of the present application, the position of the card slot 112 is not limited to this, and other embodiments are also possible. For example, the notch of the card slot 112 may be opened on the side wall 1111 forming the receiving slot 111, and the user may insert the SIM card into the card slot 112 from the side wall 1111 through the receiving slot 111.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a slot cover in a wearable electronic device according to an embodiment of the present disclosure. The slot cover 12 includes a conductive metal sheet 121, and an insulating layer 122 and a second metal protrusion 123 coated on the surface of the conductive metal sheet 121.

The conductive metal sheet 121 and the second metal protrusion 123 are made of metal, the second metal protrusion 123 is disposed at an end of the conductive metal sheet 121, and the second metal protrusion 123 is fixedly connected to the conductive metal sheet 121. The second metal bump 123 may be integrally formed with the conductive metal sheet 121, or the second metal bump 123 may be separately formed with the conductive metal sheet 121 and fixedly connected thereto by welding or the like. On the insulating layer 122, a through hole 1221 is disposed at a position corresponding to the second metal bump 123, and the second metal bump 123 protrudes from the outer surface of the insulating layer 122 through the through hole 1221. Since the common metal material is generally soft and the conductive metal sheet 121 is easily deformed and bent, the insulating layer 122 may be used to support the conductive metal sheet 121 to prevent the conductive metal sheet 121 from being deformed and bent. Meanwhile, if the conductive metal sheet 121 is exposed outside, the conductive metal sheet is easily worn, splashed with water and the like, the insulating layer 122 may be used to protect the conductive metal sheet 121, prevent the conductive metal sheet 121 from being worn or scratched, and prevent water and dust at the same time, thereby preventing the conductive metal sheet 121 from rusting or short-circuiting due to water drops or dust falling on the conductive metal sheet 121.

Wherein, the shape of the groove cover 12 can be adapted to the notch of the accommodating groove 111, and the external contour dimension of the groove cover 12 is slightly smaller than the notch of the accommodating groove 111: when the notch of the accommodating groove 111 is triangular, the groove cover 12 is triangular similar to the notch of the accommodating groove 111 and slightly smaller than the notch of the accommodating groove 111; when the notch of the storage groove 111 is rectangular, the groove cover 12 is rectangular with the length-width ratio same as that of the notch of the storage groove 111 and slightly smaller than that of the notch of the storage groove 111; when the notch of the storage groove 111 is a rounded rectangle, the cover 12 is a rounded rectangle … … having the same length to width ratio and the same radian as the notch of the storage groove 111 and slightly smaller than the notch of the storage groove 111, so that the cover 12 can be just inserted into the storage groove 111 when the cover 12 is disposed on the notch of the storage groove 111. That is, when the groove cover 12 covers the notch of the housing groove 111, the groove cover 12 completely closes the housing groove 111, and the housing groove 111 is used to house the groove cover 12. It is understood that when the slot cover 12 is disposed at the notch of the receiving slot 111, the outer surface of the insulating layer 122 of the slot cover 12 is flush with the outer surface of the housing 11, so that the whole outer surface of the wearable electronic device 10 is flat.

It should be noted that the shape of the slot cover 12 may not be adapted to the notch of the accommodating slot 111, and it is only necessary to ensure that the outer contour dimension of the slot cover 12 is smaller than the notch of the accommodating slot 111. For example, the shape of the slot cover 12 does not match the notch of the receiving slot 111, and when the slot cover 12 is disposed on the notch of the receiving slot 111, the slot cover 12 partially closes the receiving slot 111. The receiving groove 111 may contain a space, such as a small notch or a gap, in addition to the groove cover 12, through which a user may conveniently remove the groove cover 12 from the receiving groove 111, such as by picking the groove cover 12 from the receiving groove 111 with a fingernail.

When the groove cover 12 covers the notch of the receiving groove 111, the second metal protrusion 123 abuts against the first metal protrusion 113, and the second metal protrusion 123 is electrically connected to the radio frequency circuit of the wearable electronic device 10 through the first metal protrusion 113, so as to electrically connect the conductive metal sheet 121 to the radio frequency circuit of the wearable electronic device 10, so that the conductive metal sheet 121 serves as an external antenna of the wearable electronic device 10 to transmit radio frequency signals.

The Radio Frequency signal (RF-Radio Frequency signal) is an electromagnetic wave which is modulated and has a certain transmission Frequency. The radio frequency signals typically include Long Term Evolution (LTE) signals, 5G radio frequency signals, wi-Fi radio frequency signals, GPS radio frequency signals, and the like.

The LTE signal is a long term evolution LTE signal transmitted based on UMTS (Universal Mobile Telecommunications System) technical standard established by 3GPP (The 3rd Generation Partnership Project) organization, and is used for accessing a wireless communication network to implement wireless communication. LTE signals can be divided into Low frequency band (LB, frequency range 700MHz to 960 MHz), medium frequency band (MB, frequency range 1710MHz to 2170 MHz), and High frequency band (HB, frequency range 2300MHz to 2690 MHz). The Wi-Fi signals are signals which are wirelessly transmitted based on a Wi-Fi technology and are used for accessing a wireless local area network to realize network communication, and the Wi-Fi signals comprise Wi-Fi signals with the frequencies of 2.4GHz and 5 GHz; the frequency range of the GPS signal (Global Positioning System) is 1.2GHz to 1.6GHz. The 5G signals are used for accessing a wireless communication network to realize wireless communication, and the 5G signals at least comprise 5G signals with the frequency ranges of N78 (3.3 GHz-3.6 GHz) and N79 (4.8 GHz-5 GHz).

It should be noted that "transmitting" in the above "transmitting rf signals" includes receiving rf signals, transmitting rf signals, and receiving and transmitting rf signals.

The wearable electronic device 10 provided by the embodiment of the application enables the slot cover 12 to transmit radio frequency line signals by setting the conductive metal sheet in the slot cover 12 and electrically connecting the slot cover 12 to the radio frequency circuit of the wearable electronic device 10, so that the slot cover 12 is reused as an external antenna of the wearable electronic device 10. Compared with a traditional built-in antenna, the clearance area of the antenna can be increased, the interference of electronic devices inside the wearable electronic equipment to the antenna is reduced, and the receiving and transmitting efficiency of the antenna is improved.
