Fig. 1 is a schematic structural diagram of a key device including an antenna according to an embodiment of the present disclosure.

Referring to fig. 1, a key device 100 provided in the embodiment of the present application includes a key cap 101, an antenna 102, a housing 103, a switch 104, a circuit board 105, and a feeding part.

The keycap 101 encloses the antenna 102, i.e., the antenna 102 is embedded in the keycap 101. Antenna 102 is used for the receiving and dispatching electromagnetic wave, and antenna 102 can specifically be WIFI bluetooth antenna, GPS big dipper antenna, 4G 5G antenna etc..

The shell 103 is provided with a key through hole 106, and the outer diameter of the keycap 101 is smaller than the aperture of the key through hole 106, so that the keycap 101 can move in the key through hole 106 conveniently. The switch 104 may be soldered to the circuit board 105 in a patch form.

The key cap 101 may specifically include a main body 1011 and a protrusion 1012, wherein the main body 1011 encloses the antenna 102, that is, the antenna 102 is embedded in the main body 1011. The protrusion 1012 is disposed above the switch 104 so that the contact surface when the protrusion 1012 is in contact with the switch 104 can conduct pressure well to trigger the switch 104.

The key cap 101 needs to have certain flexibility, and the key cap 101 with the flexibility can obtain better feeling experience when in operation, and has the functions of buffering and protecting the antenna 102. The key cap 101 is fixed on the inner surface of the housing 103 through the adhesive 107, when downward pressure is applied to the key cap 101, the key cap 101 has a flexible characteristic, the main body 1011 can deform to some extent, the protrusion 1012 contacts with the switch 104, the observation and aiming device is operated, and meanwhile, the adhesive 107 can ensure that the key cap 101 does not fall off from the housing 103.

The key cap 101 needs to be made of a low dielectric constant material to allow electromagnetic waves to pass through without shielding the electromagnetic waves. Therefore, the key cap 101 may be made of a rubber material. Meanwhile, the keycap 101 covers the antenna 102, so that the antenna 102 is isolated from other structures of the device, particularly from a metal structure, and therefore the antenna 102 has good antenna performance.

The feeding part may connect the antenna 102 and the circuit on the circuit board 105 in a direct contact with the antenna 102, and may also connect the antenna 102 and the circuit on the circuit board 105 by coupling feeding in a non-direct contact with the antenna 102.

In some embodiments, the feeding component may connect the antenna 102 and circuitry on the circuit board 105 in direct contact with the antenna 102. The feeding means may comprise a coaxial line 201.

The coaxial line 201 can be directly welded and fixed on the circuit board 105 through the welding plate 203 to achieve the purpose of grounding the outer skin of the coaxial line 201, the coaxial line contact 202 is welded with the antenna 102 to ensure that a transceiving link is smooth, and the coaxial line 201 is used for connecting the circuit signal inside the circuit board 105 and the antenna signal contact type feed corresponding to the antenna 102. It should be noted that, the key cap 101 may be provided with an opening (not shown) at a position corresponding to the coaxial line contact 202, so as to ensure that the coaxial line contact 202 can be transmitted through the opening and welded to the antenna 102 to form a complete feeder link.

When downward pressure is applied to the keycap 101, the keycap 101 and the antenna 102 displace downward, the keycap 101 contacts with the switch 104, the switch 104 is triggered, and the observation and aiming device is operated. Coaxial line 201 has certain flexibility, and when keycap 101 took place the downward displacement, coaxial line 201 can realize certain degree bending, does not influence when guaranteeing that the receiving and dispatching link is unobstructed and operates equipment through the button. The positions of the coaxial line 201, the coaxial line contact 202 and the soldering pad 203 may also be adjusted according to the performance and structure requirements of the antenna, and are only schematic positions in the figure.

In some embodiments, the feeding means connecting the antenna 102 and the circuitry on the circuit board 105 in direct contact with the antenna 102 may also be a POGO PIN or a spring plate.

Fig. 2 is a schematic structural diagram of another key device including an antenna according to an embodiment of the present application.

Referring to fig. 2, in some embodiments, the feed component may connect the antenna 102 and circuitry on the circuit board 105 by coupling the feed in non-direct contact with the antenna 102. The feeding means may comprise coupled feeding means 204.

The coupling feeding part 204 is disposed on the surface of the circuit board 105 and below the antenna 102, and the coupling feeding part 204 is used for non-contact feeding of the circuit signal and the antenna signal of the circuit board 105 corresponding to the antenna 102.

When downward pressure is applied to the keycap 101, the keycap 101 and the antenna 102 displace downward, the keycap 101 contacts with the switch 104, the switch 104 is triggered, and the observation and aiming device is operated. When the switch 104 is pressed, the keycap 101 is not in contact with the coupling feed part 204, so that the receiving and transmitting links are ensured to be smooth through non-contact feeding, and the operation of the equipment through the key is not influenced. The position of the coupling feeding component 204 can also be adjusted according to the performance and structure of the antenna, and is only a schematic position in the figure.
