Description
Technical Field
The invention relates to the technical field of wearing equipment, in particular to wearing equipment with a wireless communication device.
Background
Currently, a wide variety of smart wearable electronic devices (e.g., smart watches, smart bracelets, etc.) are appearing on the market. The intelligent wearable electronic equipment integrates the functions of displaying the time due to the watches and the bracelets in the traditional sense, and can also realize the functions of communication, short-distance transmission, real-time positioning and the like.
For the intelligent wearable electronic device, the functions of communication, short-distance transmission, real-time positioning and the like are realized by inserting a SIM card into the intelligent wearable device. However, for the intelligent wearable electronic device to be inserted with the SIM card, the performance requirement on the antenna is also higher, and especially the size of the current intelligent wearable electronic device is smaller. When the size of the intelligent wearable electronic device is reduced, the area of the built-in circuit board is correspondingly reduced, and when the area of the ground plane of the circuit board is reduced to a certain threshold value, the performance of the antenna is reduced along with the reduction of the whole size of the circuit board. Theory and practice prove that when the length of the antenna is 1/4 of the wavelength of the radio signal and the length of the ground plane required by the antenna generally suggests 1/4 to 1/2 of the radio wavelength, the transmission and reception conversion efficiency of the antenna is highest. The length of the antenna and the length of the ground plane required by the antenna are determined according to the wavelength of radio waves during operation. For example, the center frequency of the transmission and reception of the GSM (Global System for Mobile Communication global system for mobile communications) 900 band is 935MHZ, and the wavelength of the corresponding radio wave at that frequency is 320mm, then the length of the antenna should be 1/4 the wavelength of the radio wave, i.e., 80mm; the length of the ground plane of the antenna should be 1/2 wavelength, i.e. 160mm. However, the total length of the circuit board of most intelligent wearable electronic devices is about 40mm, which is far smaller than the wavelength of 1/4 radio wave, and the requirement of the antenna on the length of the ground plane cannot be met. In addition, in addition to the GSM900 frequency band, the antenna performance may be insufficient in other frequency bands (e.g., DCS1800 (Digital Cellular System at 1800mhz digital cellular system) frequency band) due to insufficient ground plane of the circuit board.

The following detailed description will be given with reference to the accompanying drawings.
Fig. 1 to 3 are schematic structural diagrams of a wearable device 100 with a wireless communication device according to an embodiment of the invention. The wearable device 100 includes a dial portion 10 and a watchband portion 20 connected to the dial portion 10, and a circuit board 11 and a battery 12 electrically connected to the circuit board 11 are disposed in the dial portion 10. The wireless communication device includes a grounding module 30 and an antenna (not shown), the grounding module 30 is disposed in the dial portion 10, and the grounding module 30 is disposed between the circuit board 11 and the bottom of the dial portion 10, and the grounding module 30 is electrically connected to the circuit board 11. The antenna is disposed on the dial portion 10 or the watchband portion 20, and the antenna is electrically connected to the circuit board 11.
In this embodiment, the wearable device 100 may be a smart watch or a smart bracelet.
In this embodiment, the dial portion 10 may be made of a metal material, such as an aluminum alloy or a stainless steel material. Of course, the dial portion 10 may also be made of a non-metallic material, such as a plastic material. Specifically, the dial portion 10 may include a frame 10a and a bottom cover 10b integrally formed with the frame 10a, the circuit board 11 and the battery 12 are disposed in the frame 10a, a gap is formed between the circuit board 11 and the bottom cover 10b, and the grounding module 30 is disposed in the gap between the circuit board 11 and the bottom cover 10 b. Preferably, the frame 10a may be a hollow frame structure, that is, the frame 10a is a frame with two open ends; the bottom cover 10b is connected to the frame 10a to cover the bottom opening of the frame 10 a. Further, when the wearing apparatus 100 is in the wearing state, the bottom cover 10b is parallel to the arm 200 of the wearer.
Further, the dial portion 10 further includes a display 13, the display 13 is connected to the top of the frame 10a to cover the top opening of the frame 10a, and the display 13 is electrically connected to the circuit board 11 and the battery 12, and the display 13 is used for realizing the image display function of the wearable device 100.
Further, the band portion 20 may be made of a metal material, such as aluminum alloy or stainless steel, which is suitable for the dial portion 10. Of course, the wristband portion 20 may alternatively be made of a non-metallic material, such as silicone, leather, or nylon.
In the present embodiment, the circuit board 11 includes an upper surface 11a and a lower surface 11b that are disposed opposite to each other, the lower surface 11b being disposed toward the bottom of the dial portion 10, and the upper surface 11a being disposed toward the display 13 of the dial portion 10. Specifically, a signal feed point 11c and a signal feed point 11d are provided on the upper surface 11a of the circuit board 11, the signal feed point 11c and the signal feed point 11d being provided in the vicinity, and the antenna being connected to the circuit board 11 through the signal feed point 11c and the signal feed point 11d. It will be appreciated that in other embodiments, the upper surface 11a of the circuit board 11 may also be provided with only the signal feed point 11c, without the signal feed point 11d.
Further, the battery 12 is disposed on the upper surface 11a of the circuit board 11, so that the display 13 is connected with the battery 12, and meanwhile, the internal space of the frame 10a can be reasonably utilized, which is beneficial to the arrangement and installation of each component. It should be understood that, in other embodiments, the battery 12 may be disposed on the lower surface 11b of the circuit board 11, and then the display 13 is electrically connected to the battery 12 through the internal space of the frame 10a and the lower surface 11 b.
Further, the battery 12 is connected to the circuit board 11 through a grounding member (not shown). Specifically, the grounding member may be a conductive cloth, and the circuit board 11 includes a main ground unit (not shown), and the battery 12 is connected to the main ground unit through the grounding member (not shown).
Further, the grounding module 30 is disposed on the lower surface 11b of the circuit board 11, and the grounding module 30 is directly connected to the main ground unit of the circuit board 11 through a conductive element, so as to increase the grounding area of the antenna by using the grounding module 30. The grounding module 30 is connected with the circuit main board 11 to increase the main unit area of the circuit main board 11, so that the length requirement of the antenna on the ground plane of the circuit main board 11 can be met while the volume of the circuit main board 11 is not increased, and the performance of the antenna is improved.
Further, the grounding module 30 may be made of conductive material, such as copper sheet, steel sheet, or stainless steel sheet. The conductive element 31 may be preferably a conductive spring, a conductive adhesive or a conductive foam. For example, when the conductive element 31 is a conductive spring or a conductive foam, the conductive spring or the conductive foam may be disposed on a surface of the grounding module 30 facing the lower surface 11b of the circuit board 11, and then the other end of the conductive spring or the conductive foam is abutted against the lower surface 11b of the circuit board 11, so that the grounding module 30 and the circuit board 11 can be conducted. When the conductive element 31 is conductive adhesive, the conductive adhesive is only required to be disposed on the surface of the grounding module 30, and then the conductive adhesive is adhered to the lower surface 11b of the circuit motherboard 11.
Of course, the grounding module 30 may be indirectly connected to the main ground unit of the circuit board 11 through the conductive member 31. For example, the conductive element 31 may be configured as a conductive connection wire, and then one end of the conductive element 31 is electrically connected to the grounding module 30, and the other end of the conductive element 31 is routed to the grounding component of the battery 12, so that the grounding module 30 is indirectly connected to the main ground unit of the circuit board 11 through the conductive element 31 and the grounding component. It will be appreciated that other electronic devices within the wearable device may also be connected to the main ground unit of the circuit board 11 via a ground connection to provide electrical continuity, and thus the ground module 30 may also be connected to the ground connection of other electronic devices within the wearable device, for example, to the ground connection of the display 13 or to the ground connection of a speaker.
Further, the grounding module 30 is disposed in parallel with the bottom of the dial portion 10, that is, the grounding module 30 is disposed in parallel with the bottom cover 10b of the dial portion 10. When the wearable device 100 is in the wearing state, the grounding module 30 is disposed parallel to the arm 200 of the wearer. Since the human arm is a lossy conductor medium, a portion of the electromagnetic waves are absorbed when they encounter the human arm, and therefore the antenna performance within the wearable device 100 may decay when the wearable device 100 is worn on the arm 200 of the wearer, the closer the antenna is to the arm of the wearer, the more attenuated. In addition, when the wearable device 100 is in the wearing state, a gap is formed between the main ground unit of the circuit board 11 and the arm 200 of the wearer, and according to the electromagnetic field radiation theory, a high-frequency current is generated on the circuit board 11, and an induced current is generated by the arm 200 of the wearer, so that the arm of the wearer can also be used as a reference ground for the antenna of the wearable device 100.
However, if the circuit board 11 is far from the arm 200 of the wearer, the induced current received on the arm of the wearer is small at this time, and the influence of the arm 200 of the wearer on the antenna at this time appears as loss, that is, the performance of the antenna is attenuated. When the circuit board 11 is close to the arm 200 of the wearer, the induced current received by the arm of the wearer is larger, and the arm 200 of the wearer can be used as the antenna reference ground, so that the radiation efficiency of the antenna can be improved. Therefore, the grounding module 30 is disposed parallel to the bottom cover 10b of the dial portion 10, that is, the grounding module 30 is disposed parallel to the arm 200 of the wearer, that is, the distance between the main ground unit of the circuit board 11 and the arm 200 of the wearer can be reduced by using the grounding module 30, that is, the gap between the main ground unit of the circuit board 11 and the arm 200 of the wearer is reduced, so that the induced current received by the arm 200 of the wearer is large, the reference ground of the antenna is prolonged, the radiation efficiency of the antenna is improved, and the performance of the antenna is ensured.
In the present embodiment, an antenna is provided in the dial portion 10, and the antenna is connected to the circuit board 11 through a signal feeding point 11c to achieve reception and/or radiation of signals on the circuit board 11. It will be appreciated that in other embodiments, the antenna may also be provided within the wristband portion 20.
Referring to fig. 4, a radiation efficiency diagram of an antenna (i.e., the added grounding module 30 in fig. 4) in a wearable device 100 with a wireless communication device and an antenna (i.e., the original non-grounding module in fig. 4) in a wearable device according to the prior art are provided in an embodiment of the invention. As can be seen from fig. 4, the embodiment of the present invention adds the grounding module 30, the radiation efficiency of the antenna is obviously improved before the frequency of 2000MHZ, that is, the frequency range of less than 2000MHZ, while the embodiment of the present invention adds the design of the grounding module 30 after the frequency of 2000MHZ, and the radiation efficiency of the antenna is not obvious compared with the radiation efficiency of the antenna without the grounding module in the prior art. That is, the addition of the grounding module 30 can improve the radiation efficiency of the wearable device 100 in the frequency band below 2000MHZ, and overcomes the defect that the antenna performance below 2000MHZ is reduced due to the reduced size of the main ground unit of the circuit board 11 in the wearable device 100.
According to the wearable device with the wireless communication device, the grounding module is arranged between the circuit main board and the bottom of the dial plate part, and the grounding module is electrically connected to the circuit main board. On the one hand, the grounding module is used for increasing the main ground unit of the circuit main board so as to overcome the defect that the main ground unit of the circuit main board cannot meet the antenna performance requirement due to the reduction of the length of the circuit main board; on the other hand, when the wearing equipment is in a wearing state, because a certain gap is formed between the circuit main board and the arm of the wearer, the gap between the circuit main board and the arm of the wearer is reduced by the grounding module, the induction current received by the arm of the wearer can be larger, the reference ground of the antenna is prolonged, the radiation efficiency of the antenna is improved, and the performance of the antenna is improved.
The wearable device with the wireless communication device disclosed in the embodiment of the present invention is described in detail, and specific examples are applied to illustrate the principle and implementation of the present invention, and the description of the above embodiments is only used to help understand the wearable device with the wireless communication device and the core idea thereof; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
