Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and fig. 2, an external power supply device 10 applied to a wearable device 20 in the embodiment of the present application includes a housing 11, a battery 12 disposed in the housing 11, a charging/discharging interface 13 electrically connected to the battery 12, a grounding metal plate 14 disposed in the housing 11, and an antenna interface 15 coupled to the grounding metal plate 14 and configured to communicate with the wearable device 20.
The grounding metal plate 14, which is used as a reference ground for the antenna added to the wearable device 20, may be disposed inside or outside the housing 11 of the external power supply apparatus 10, and the housing 11 is generally made of an insulating material to avoid affecting the performance of the antenna.
The charge and discharge interface 13 may be a Micro USB interface, a Type-C USB interface, or a Pogo pin (Pogo pin), and is matched with the charge interface of the wearable device 20. In one embodiment, the charging and discharging interface 13 is a Pogo pin, which includes a positive terminal 131 and a negative terminal 132 disposed on the housing 11.
Referring to fig. 1, in an embodiment, the negative terminal 132 of the charging/discharging interface 13 of the external power device 10 is multiplexed as the antenna interface 15. The main board of the wearable device 20 is conducted with the grounding metal plate 14 by utilizing the grounding of the charging and discharging interface 13 without introducing an additional connection mode, so that the structural complexity and the circuit complexity are reduced, and the cost is saved. In another embodiment, the antenna interface 15 of the external power supply device 10 is independently disposed, and includes a feeding terminal (not shown) disposed on the housing 11, where the feeding terminal is a Pogo pin, or any type of conductive member such as a contact spring, a snap-fit structure, or the like. Generally, the charging/discharging interface 13 and the antenna interface 15 of the external power supply device 10 are disposed at the bottom of the housing 11.
Through introducing the external reference ground that ground connection metal sheet 14 regarded as wearable equipment 20 self antenna at external power supply unit 10, when external power supply unit 10 was installed on wearable equipment 20, self antenna on wearable equipment 20 is receiving external power supply unit 10 to influence under the difficult circumstances of received signal, and external reference ground constitutes the coupling branch of antenna, has obviously promoted the performance of antenna, can provide fine signal reception ability for wearable equipment 20, satisfies user's communication, location demand.
Further, the ground metal plate 14 is coupled with the case of the battery 12. The casing of the battery 12 is generally made of metal, so that the casing of the battery 12 is used as an antenna branch of the wearable device 20 to participate in radiation, the signal receiving capability is enhanced, and the radiation of the signal is not blocked. The connection method of the grounding metal plate 14 and the battery 12 is not limited to the circular conductor 141 in fig. 1 and 2, and may be any shape or material conductor.
In a second aspect of the present invention, a portable device is provided, which includes the external power supply apparatus 10 and the wearable device 20, and the antenna interface 15 of the external power supply apparatus 10 is in butt joint with the external antenna interface of the wearable device 20.
