Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Examples
Fig. 1 is a schematic top view of a watch with a wireless charging device according to an embodiment of the present invention, where the watch may implement a wireless charging function through the wireless charging device. The watch with the wireless charging device provided by the embodiment of the invention comprises: PCB board 110, housing 120, SIM card holder 130, wireless charging receiving coil 140, and SIM card cover 150 provided with ferrite.
The housing 120 is provided with an installation opening, the card slot of the SIM card holder 130 is coaxially disposed with the installation opening and the central opening of the wireless charging receiving coil 140, the bottom surface of the SIM card holder 130 is installed on the PCB 110, and the SIM card cover 150 is detachably connected with the installation opening.
Specifically, the wireless charging receiving coil requires at least one receiving coil and at least one transmitting coil in the charging process. The transmitting coil is arranged in the charging base station, the receiving coil is arranged in the equipment to be charged, and electric energy is transmitted through an electric coupling technology. In this embodiment, the device to be charged is a wristwatch, and the charging base station may be placed within a predetermined distance from the wristwatch to be charged. The watch case 120 is provided with a mounting opening, and the SIM card holder 130 has a slot for holding a SIM card. The card slot of the SIM card holder 130 is coaxially arranged with the mounting opening and the central opening of the wireless charging receiving coil 140, which is beneficial to fixing the SIM card holder 130. The bottom surface of the SIM card holder 130 is mounted on the PCB 110, wherein a circuit formed by welding or attaching various components is disposed on the PCB 110, and the circuit can be used as an energy storage component in the wireless charging process and provides electric energy for the watch during operation.
Optionally, the SIM card holder 130 and the wireless charging receiving coil 140 are both placed at the bottom of the watch, so that enough space is left at the top of the watch to set up a watch dial screen; moreover, the bottom of the watch is larger than the side surface of the watch, so that a larger wireless charging receiving coil 140 can be placed, and the larger wireless charging receiving coil 140 can generate higher charging efficiency.
The SIM card cover 150 is detachably connected to the mounting opening, where the SIM card cover 150 contains ferrite. In the wireless charging process, the transmitting coil and the receiving coil can generate the leakage problem of the magnetic force line in the electric energy transmission process, and the ferrite plays a role of magnetic shielding. The SIM card holder 130 and the PCB board 110 are mostly made of metal, and the SIM card cover 150 is provided with ferrite, so that the metal will not generate eddy current to generate heat and affect the efficiency, and will not leak the magnetic force line.
In addition, ferrite provided on the SIM card cover 150 does not affect the overall EMC. In particular, EMC (Electromagnetic Compatibility ) refers to the ability of a device or system to operate satisfactorily in its electromagnetic environment without intolerable electromagnetic disturbance to any device in its environment. Thus, EMC includes two requirements: on the one hand, electromagnetic disturbance generated by equipment on the environment in the normal operation process cannot exceed a certain limit value; on the other hand, the device has a certain degree of immunity, namely electromagnetic sensitivity, to electromagnetic disturbance existing in the environment. In the embodiment of the present invention, the fact that the whole EMC is not affected means that the ferrite is disposed on the SIM card cover 150 so that the watch does not generate too high electromagnetic disturbance in the environment where the watch is located, or the watch has a degree of immunity to electromagnetic disturbance in the environment where the watch is located.
In order to enable the watch to have less magnetic lines to leak and higher charging efficiency in the wireless charging process, the watch further comprises an annular receiving coil ferrite 160, wherein the receiving coil ferrite 160 is arranged between the wireless charging receiving coil 140 and the PCB 110 and is tightly attached to the wireless charging receiving coil 140; the card slot of the SIM card holder 130 faces the opening of the receiving coil ferrite 160.
The watch further includes an annular receiving coil ferrite 160, where the receiving coil ferrite 160 is disposed between the wireless charging receiving coil 140 and the PCB 110, and is tightly attached to the wireless charging receiving coil 140. The magnetic force lines of the wireless charging receiving coil 140 in the wireless charging process are shielded to prevent the magnetic force lines from leaking to the PCB 110, so that heat is reduced, and the charging efficiency is improved. The SIM card has a number of metal contacts 170 for contact with the metal contacts on the card slot. The slot of the SIM card holder 130 faces the opening of the receiving coil ferrite 160, which is advantageous for shielding the magnetic lines from leaking to the metal contacts 170 on the SIM card.
The watch incorporates the SIM card holder 130, and in this particular case, the receiving coil ferrite 160 is formed in a ring shape, and the width of the ring surface of the receiving coil ferrite 160 in the radial direction is larger than the width of the coil surface of the wireless charging receiving coil 140.
Optionally, the receiving coil ferrite 160 is made into a ring shape, and the middle opening portion is used for embedding the SIM card holder 130 or the SIM card cover 150, where the ring shape may be a circular ring or a rectangular ring, and the specific ring shape may be determined according to the SIM card holder 130 or the SIM card cover 150 that is embedded and attached to the ring shape.
Fig. 2 shows a schematic cross-sectional view of a wristwatch with a wireless charging device in direction AB of fig. 1. It should be noted that, several metal contacts 170 on the SIM card are not shown in fig. 2. The width of the annular surface of the receiving coil ferrite 160 in the radial direction is larger than the width of the coil surface of the wireless charging receiving coil 140, so that the contact area of the annular surface of the receiving coil ferrite 160 is ensured to be larger than the area of the wireless charging coil 140 on the plane, and the leakage of magnetic force lines is prevented. Optionally, in the wireless charging process, the transmitting coil and the receiving coil are generally made into a circular ring shape, which is beneficial to electric energy transmission.
In addition, the coil surface of the wireless charging receiving coil 140 facing the side of the PCB board 110 is entirely covered by the annular surface of the receiving coil ferrite 160.
In order to achieve a better shielding effect, the coil surface facing the PCB board 110 along the wireless charging receiving coil 140 is entirely covered by the annular surface of the receiving coil ferrite 160. This better prevents the magnetic lines from leaking out onto the PCB 110.
Alternatively, when the wireless charging receiving coil 140 is in a circular ring shape, the radial width of the SIM card cover 150 provided with ferrite may be set smaller than the diameter of the wireless charging receiving coil 140. In order to obtain better charging efficiency and magnetic shielding effect, the radial width of the SIM card cover 150 may be slightly larger than the opening of the receiving coil ferrite 160, which is not particularly limited herein, and in practical application, the radial width of the SIM card cover 150 may also be smaller than the opening of the receiving coil ferrite 160, except that the charging efficiency and magnetic shielding effect may be reduced.
Optionally, the SIM card holder 130 is soldered on the PCB 110.
In order to fix the SIM card holder 130 on the watch, and further fix the SIM card in the card slot of the SIM card holder 130 more firmly, the SIM card holder 130 is welded on the PCB 110, so that the SIM card holder 130 and the PCB 110 are fixed as a whole.
In order to enable a user to conveniently operate during charging, the watch does not need to be placed at will in the direction of the watch, and the geometric center of the clamping groove is opposite to the geometric center of the dial plate of the watch.
The geometric center of the clamping groove is opposite to the geometric center of the dial of the watch, so that the positions of the clamping groove and the wireless charging receiving coil 140 are also fixed. Because the position relation between the transmitting coil and the receiving coil is required to be relatively fixed in the wireless charging process, optionally, when the SIM card seat 130 is embedded in the middle of the wireless charging receiving coil 140, the geometric center of the wireless charging receiving coil 140 is opposite to the geometric center of the watch dial, so that a user does not need to distinguish the watch direction to be randomly placed in the charging process, and the defect that the watch position direction needs to be fixed in the charging process is avoided. The geometric center of the wireless charging receiving coil 140 is opposite to the geometric center of the watch dial, so that the direction of the watch is changed in the wireless charging process of the watch, the direction of the wireless charging receiving coil 140 is not changed, and the relative positions and directions of the wireless charging receiving coil 140 and the transmitting coil of the charging base station are not changed.
In one specific implementation, the SIM card cover 150 is threaded with the mounting port. Alternatively, the SIM card cover 150 and the mounting opening are screwed, where screwing refers to a threaded connection, that is, a detachable connection in which a threaded member or a threaded portion of a connected member is used to integrally connect the connecting member. The screw member includes a bolt, a stud, a screw, a set screw, and the like.
In addition, the SIM card cover 150 and the mounting port may also be in a nested connection. The SIM card cover 150 may be in a nested connection with the mounting port, besides being screwed to the mounting port. The nested connection may be implemented by a ferrule or may be implemented directly between the SIM card cover 150 and the mounting port. Alternatively, in order to make the sealing effect better, the area of the side of the SIM card cover 150 near the mounting opening may be made slightly larger than the mounting opening.
The ferrite is integrally formed with the SIM card cover 150. In the SIM card cover 150 provided with ferrite, the ferrite and the SIM card cover 150 are integrally formed. The ferrite raw material is in a powder form, and the ferrite raw material in a powder form can be doped into the raw material for manufacturing the SIM card cover 150 to manufacture the SIM card cover 150 provided with ferrite; the finished ferrite product may be formed in a sheet shape, and the sheet-shaped ferrite may be injection-molded into the SIM card cover 150 by means of a grinding tool.
The ferrite is fixed to a side of the SIM card cover 150 facing the SIM card slot. Alternatively, ferrite may be fixed to a side of the SIM card cover 150 facing the SIM card slot. The ferrite can be selected from lamellar ferrite, and the fixing mode can be adhesion or close adhesion.
In the embodiment of the invention, a watch with a wireless charging device is provided, wherein a PCB (printed circuit board), a shell, an SIM card holder, a wireless charging receiving coil and an SIM card cover provided with ferrite are arranged in the watch, the shell is provided with a mounting port, a clamping groove of the SIM card holder is coaxially arranged with the mounting port and a central opening of the wireless charging receiving coil, the bottom surface of the SIM card holder is arranged on the PCB, and the SIM card cover is detachably connected with the mounting port.
