It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a first structure of an NFC payment watch according to an embodiment of the present application, and fig. 2 is an exploded schematic diagram of the NFC payment watch shown in fig. 1. The present embodiments provide an NFC payment watch 100, the NFC payment watch 100 comprising a passive NFC payment structure 10 and a watch body 20.

The watch body 20 may include a dial and a wearing structure connected to the dial to wear the watch body 20 on a user's hand. The dial may be used to display related information, for example, the dial may display at least one of time, date, weather, sports information, physical health information, electricity, etc. The dial is internally provided with a wireless communication circuit, such as a Bluetooth communication circuit, a wifi communication circuit and the like, and can communicate with external equipment, such as a mobile phone, so as to control interaction with the external equipment, such as displaying incoming call information of the external equipment, controlling audio playing application of the external equipment, switching a display interface according to an external equipment instruction, and changing settings or information according to the external equipment instruction. The watch body 20 may be a wristwatch that does not have a wireless NFC payment function, such as a smart watch, an electronic watch, a mechanical watch, or the like.

The wearing structure can be set according to wearing requirements. For example, the wearing structure may be a wristband 24, the wristband 24 being connected to a dial, the wristband 24 may be used to wear the watch body 20 on a user's wrist. The present embodiment does not limit the structure of the wristband, and any wristband is within the scope of the present embodiment. The wearing structure may also be a watch chain, which is connected to the dial, and which may be used to wear the watch body 20 in the chest, the pocket, or the like of the user.

The passive NFC payment structure 10 may interact with an external NFC payment device to make NFC payments. For example, the passive NFC payment structure 10 may enable bus fare payment, subway fare payment, canteen payment, and other scenarios that support passive NFC payment. In some examples, the passive NFC payment circuit 14 may also implement a recharging function.

The passive NFC payment structure 10 comprises a carrier 12 and a passive NFC payment circuit 14, the passive NFC payment circuit 14 being arranged on the carrier 12. The passive NFC payment structure 10 is detachably mounted to the watch body 20, and the watch body 20 comprises a first part to which the passive NFC payment structure 10 is attached, the carrier 12 being shaped to match the shape of the first part.

The passive NFC payment structure 10 is detachably mounted on the watch body 20, so that the watch body 20 which does not support the passive NFC payment can be changed into the NFC payment watch 100 which supports the NFC payment by mounting the passive NFC payment structure 10. The passive NFC payment structure 10 is detachably mounted on the watch main body 20, the carrier 12 of the passive NFC payment structure 10 is matched with the first part of the watch main body 20 in shape, the carrier 12 can be very conveniently mounted on the first part of the watch main body 20, the structure of the watch main body 20 does not need to be changed, the watch main body 20 does not need to be arranged by re-opening the mould, and the cost is greatly reduced. When the passive payment structure is mounted on the outer surface of the watch body 20, the carrier 12 is matched with the first part in shape, so that the watch body can be conveniently and detachably mounted, and the whole structure is matched with attractive appearance without obvious foreign body sensation.

It should be noted that the material of the carrier 12 may be set according to needs, for example, the material of the carrier 12 may be plastic, PCB board, or FPC board.

Referring to fig. 3, fig. 3 is an exploded view of the NFC payment watch shown in fig. 1 at another angle. In some embodiments, the first portion is a housing 22 and the carrier 12 is removably disposed in the housing 22. The carrier 12 may carry the passive NFC payment circuit 14 for convenient mounting to the housing 22, thereby changing the watch body 20 without passive NFC payment to an NFC payment watch 100 capable of supporting passive NFC payment. In addition, the carrier 12 is detachably disposed in the housing 22, so that the carrier 12, i.e., the passive NFC payment structure 10, is convenient to mount. Illustratively, the carrier 12 may be adhered to the housing 22, the carrier 12 may be engaged with the housing 22, and the carrier 12 may be magnetically coupled to the housing 22.

The carrier 12 is matched to the shape of the housing 22. For example, the shape and size of the carrier 12 is the same as or similar to the shape and size of the bottom surface of the housing 22. The passive NFC payment structure 10 is thinner, and after the carrier 12 is disposed on the bottom surface of the housing 22, the difference is hardly seen in the appearance, and the passive NFC payment structure 10 can be well matched with the watch body 20. After some wristwatches are manufactured by some wristwatches factories, the passive NFC payment structure 10 can be arranged on the wristwatches of the existing models, the original mold is not required to be opened again, the wristwatches (namely the wristwatch main body 20) are continuously manufactured by using the original mold, and the NFC payment wristwatch 100 capable of supporting the passive NFC payment can be formed by arranging the passive NFC payment structure 10 on the back of the wristwatches.

In some examples, when watch body 20 is worn on a user's wrist, housing 22 includes a bottom surface that contacts the user's wrist, and carrier 12 may be removably disposed on the bottom surface of housing 22. Because the passive NFC payment structure 10 is thinner, the carrier 12 is attached to the bottom surface of the housing 22 with less impact on the watch body 20 and substantially does not affect the user's fit. Of course, in other examples, the carrier 12 may be disposed at other locations of the housing 22. Such as on the side or top of the housing 22.

In some examples, the carrier may be removably disposed within the housing. Because passive NFC payment structure thickness is thinner, can paste and locate inside the casing, less to the structure influence in the casing. For example, the carrier is attached to the inside of the display screen of the watch body.

Referring to fig. 4 and fig. 5, fig. 4 is a schematic diagram of a second structure of the NFC payment watch according to the embodiment of the present application, and fig. 5 is a schematic diagram of a structure of the NFC payment watch shown in fig. 4 at another angle. In some embodiments, the housing 22 includes a first light transmissive portion 222 and the carrier 12 includes a second light transmissive portion 122, the first light transmissive portion 222 and the second light transmissive portion 122 being stacked. The watch body 20 includes a main board (not shown) disposed in the casing 22, and an optical detection sensor (not shown) is disposed on the main board, and the optical detection sensor is disposed opposite to the first light-transmitting portion 222 and the second light-transmitting portion 122, so as to detect through the first light-transmitting portion 222 and the second light-transmitting portion 122.

It will be appreciated that optical detection sensors need to transmit and/or receive optical signals to make measurements. Specifically, the optical detection sensor is disposed opposite to the first light-transmitting portion 222 and the second light-transmitting portion 122, so as to emit and/or receive the optical signals transmitted through the first light-transmitting portion 222 and the second light-transmitting portion 122 for detection. The carrier 12 may be disposed on the bottom surface of the housing 22, and the second light-transmitting portion 122 of the carrier 12 does not affect the detection performed by the optical light detection sensor.

The main board in the watch body 20 is provided with an optical detection sensor which can be set as required. Illustratively, the optical detection sensor may include at least one of an optical heart rate sensor, a blood oxygen saturation (SpO 2) sensor, an ECG sensor, and the like. The optical heart rate sensor can detect heart rate, the principle is that the skin and nearby blood vessels closely attached to the sensor are irradiated by LED green light, and the heart rate state is judged by measuring and calculating the fluctuation of absorbed light, so that the heart rate sensor can assist in motion detection, and can also detect heart abnormality and timely feedback alarm. The SpO2 sensor examines the color of blood to see the oxygen content therein, deoxygenated blood flowing back to the lungs through veins is slightly more red than whole oxygen blood in arteries, and the sensor measures the relative reflectance of red and infrared light in the blood through the wrist and observes its changes with the heartbeat to estimate the SpO2 value. The function of the ECG sensor is to detect the tiny electrical pulses emitted by the heart at each heartbeat, and to detect the heart signal for this minute through electrodes on the wearable device.

In some examples, the second light-transmitting portion 122 may be a transparent plate, and the passive NFC payment circuit 14 includes an NFC antenna 142, where the NFC antenna 142 is ring-shaped, and the NFC antenna 142 includes a transparent conductor (e.g., ITO) at least partially positioned in the second light-transmitting portion 122. The light transmission function of the second light transmission part 122 is not affected, and the NFC antenna 142 can be conveniently arranged on the second light transmission part 122. The size of the NFC antenna 142 is not affected, so that the antenna performance can be met, and the size of the NFC antenna 142 cannot be oversized. The size of the second light-transmitting portion 122 is set according to the size of the first light-transmitting portion 222 of the housing 22. When the size of the second light-transmitting portion 122 is small, the NFC antenna 142 may be partially disposed within the second light-transmitting portion 122. When the size of the second light-transmitting portion 122 is large, the NFC antenna 142 may be disposed entirely within the second light-transmitting portion 122.

Other light-tight elements (e.g., the passive NFC chip 144) in the passive NFC payment circuit 14 are disposed in a manner of being offset from the second light-tight portion 122 and the NFC antenna 142, such as being disposed outside the NFC antenna 142.

In some examples, the second light-transmitting portion 122 may be a through-hole structure, and the passive NFC payment circuit 14 includes an NFC antenna 142, where the NFC antenna 142 is annular and the NFC antenna 142 is disposed around the second light-transmitting portion 122. The annular NFC antenna 142 may be disposed around the second light-transmitting portion 122 of the through hole structure, which does not affect the disposition of the NFC antenna 142, nor the use of the second light-transmitting portion 122, and may also reduce the size of the passive NFC payment circuit 14.

It should be noted that the NFC antenna 142 may be made of copper or other metals or metal alloys. Of course, the NFC antenna 142 may also be made of a transparent conductor (such as ITO).

In some examples, the housing 22 is not provided with the first light-transmitting portion 222, the carrier 12 is not provided with the second light-transmitting portion 122, and other elements in the passive NFC payment circuit 14 (such as the passive NFC chip 144) may be disposed in the middle of the loop NFC antenna 142 or may be disposed outside the loop NFC antenna 142.

In some embodiments, the passive NFC payment structure 10 further includes a heat conducting structure and a heat insulating structure, where the heat conducting structure and the passive NFC payment circuit 14 are disposed on the same side of the carrier 12 and are located on a side of the carrier 12 facing the housing 22, the heat conducting structure is used for guiding heat of the passive NFC payment circuit 14 into the housing 22, and considering that the passive NFC payment structure 10 is disposed on a side of the watch body 20 facing a user, the heat insulating structure is disposed on a side of the carrier 12 facing away from the passive NFC payment circuit 14, so that the passive NFC payment circuit 14 can be prevented from affecting the user after heating, and the heat conducting structure can conduct heat generated by the passive NFC payment circuit 14 to the housing 22 of the watch body 20 to dissipate heat, so that the passive NFC payment circuit 14 can dissipate heat and not affect the user.

In some embodiments, the passive NFC payment circuit 14 includes an NFC antenna 142 and an NFC chip 144, where the NFC chip 144 is capable of NFC communication with an external device via the NFC antenna 142 for consumption, and the NFC chip 144 is capable of NFC communication with a mobile terminal via the NFC antenna 142 to enable the mobile terminal to obtain a record of consumption of the passive NFC payment structure 10. The passive NFC payment circuit 14 may not only make NFC payments for consumption, but may also transmit a consumption record to a mobile terminal (e.g., a cell phone or tablet computer) so that a user may query the consumption record. The consumption record not only comprises historical consumption information, but also can comprise the current residual amount, so that a user can conveniently know the current residual amount in time and recharge in time, and the problem that normal consumption cannot be performed due to insufficient residual amount is avoided. Whether or not the watch body 20 is a displayable watch (e.g., the watch body 20 is a smart watch, a mechanical watch, or a general electronic watch), the mobile terminal may obtain its consumption record by communicating with the passive NFC payment circuit 14.

In some examples, the passive NFC payment circuit 14 may also communicate with the mobile terminal to recharge the remaining amount of the passive NFC payment circuit 14, facilitating consumption by the user with the passive NFC payment circuit 14.

In some embodiments, referring to fig. 2, the watch body 20 includes a main board, and the passive NFC payment structure 10 is connected to the main board in a wired or wireless manner, and the main board can obtain consumption information of the passive NFC payment structure 10. The watch body 20 further includes a display screen 28, the display screen 28 being connected to the main board, the display screen 28 being capable of displaying consumption information.

The display 28 of the watch body 20 can display information such as consumption information, remaining amount, etc. without using an external device such as a mobile terminal or a card reader. The passive NFC payment circuit 14 may be connected wirelessly or by wire to the main board of the watch body 20. The wireless connection may be a bluetooth connection or the like.

In addition, the carrier 12 is detachably arranged on the watchband 24, so that the carrier 12, namely the passive NFC payment structure 10, is convenient to install. Illustratively, the carrier 12 may be affixed to the wristband 24, the carrier 12 may be snapped to the wristband 24, and the carrier 12 may be magnetically coupled to the wristband 24.

The carrier 12 is matched to the shape of the wristband 24. For example, the shape and size of the carrier 12 may be the same or similar to the shape and size of the bottom or top surface of the wristband 24. The passive NFC payment structure 10 is thinner, and the carrier 12 is arranged on the bottom surface or the top surface of the watchband 24, so that the difference is hardly seen in the appearance, and the passive NFC payment structure 10 can be well matched with the watch body 20.

The trim area 126 of the carrier 12 is devoid of components and circuitry and is trimmed without affecting the operation of the passive NFC payment circuit 14. At the same time, the cropped regions 126 do not affect the stability of the non-cropped regions after they have been cropped. In some examples, after the watch body 20 and the passive NFC payment structure 10 are obtained, after the position where the passive NFC payment structure 10 is mounted on the watch body 20 is determined, the passive NFC payment structure 10 is correspondingly cut according to the shape and the size of the position of the watch body 20, so that the cut passive NFC payment structure 10 and the watch body 20 are matched.
