Description

Technical Field

[0001] The present application relates to the field of wearable devices, and in particular, to a wearable device charging device, a cellular communication method and a system. Background Art

[0002] Smart devices such as mobile phones can achieve cellular communication through their configured SIM (Subscriber Identity Module) cards and cellular modules. However, in some special circumstances, smart devices cannot achieve cellular communication, for example, due to arrears, abnormalities in the cellular module, or the device having no SIM card. Therefore, there is an urgent need for a device that can provide cellular communication for smart devices under special circumstances.

[0003] Some wearable devices and their storage devices are usually carried by users due to their portability. The storage devices of some wearable devices are charging devices for the wearable devices. For example, due to the small size of TWS (Ture Wireless Stereo, true wireless headphones), a corresponding charging box is usually configured so that the TWS can be placed in the charging box for charging and storage.

[0004] Currently, charging devices for wearable devices generally do not have a structure that enables smart devices to achieve cellular communication. Summary of the invention

[0005] In view of this, the present application aims to provide a wearable device charging device, a cellular communication method and system, so as to provide a portable device that can enable smart devices to achieve cellular communication.

[0006] In a first aspect, an embodiment of the present application provides a wearable device charging device, comprising: a data transmission interface; a power module and a charging module, the charging module being connected to the power module and the data transmission interface respectively, the data transmission interface being used to access an external power supply to charge the power module through the charging module and the external power supply, and the charging module being also used to connect a wearable device to obtain electrical energy from the power module to charge the wearable device; a processor being connected to the data transmission interface; a cellular communication module being connected to the processor and being used to access a cellular network for cellular communication; the processor being also used to receive data from the cellular communication module during cellular communication, or to send data to the cellular communication module; the data transmission interface being also used to connect to a smart device through a data line, and the processor being also used to, in response to access by the smart device through the data transmission interface, forward data from the cellular communication module during cellular communication to the smart device through the data line and send data sent by the smart device to the cellular communication module, so that the smart device can indirectly access the cellular network.

[0007] The charging device of a wearable device is usually small and easy to carry. In the embodiment of the present application, the charging device of the wearable device can realize the function of charging the wearable device through the data transmission interface, the power module and the charging module. By reusing the data transmission interface, the charging device can be connected to the data line and connected to the smart device through the data line. The processor and the cellular communication module are set in the charging device, so that the charging device can access the cellular network for communication. Then, through the processor, the data transmission interface, and the forwarding of the data line, the data in the cellular communication process can be received by the smart device or sent to the cellular module, so that the smart device can access the cellular network for communication through the wearable device charging device, meeting the needs of the smart device for cellular network communication when it cannot access the cellular network.

[0008] In one embodiment, the wearable device is a true wireless headset, and the wearable device charging device is a charging box of the true wireless headset.

[0009] True wireless earphones are usually placed in a charging box for storage and charging. Generally, if a user carries true wireless earphones, he or she usually carries a charging box. The true wireless earphones are small in size, so the charging box is also small in size, which is easy to carry. In the embodiment of the present application, the charging box of the true wireless earphones is used to realize the function of the wearable device charging device. Since the true wireless earphones and the charging box are easy to carry, the smart device used by the user can access the cellular network in more scenarios.

[0010] In one embodiment, the data transmission interface is a type-c (a universal serial bus interface form factor standard) interface.

[0011] Different ports can be set in the type-c interface to achieve multiplexing of charging and data transmission. At present, the type-c interface is widely used. For example, the interface of most smart devices such as mobile phones and tablets is the type-c interface. Therefore, in the embodiment of the present application, the type-c interface is used as the data transmission port of the wearable device charging device, which has greater applicability and can meet the needs of more devices to access the cellular network.

[0012] In one embodiment, the cellular communication type supported by the cellular communication module includes at least one of 2G communication, 3G communication, 4G communication, and 5G communication.

[0015] In the embodiment of the present application, the smart device can also be connected through the short-range wireless communication module, and the cellular communication data can be forwarded through the short-range wireless communication module and the processor, so that the smart device can indirectly access the cellular network. Compared with the connection through the data transmission interface, the wireless connection method is simpler and does not require a data cable connection, which is easy to carry. At the same time, the wearable device charging device can also connect to the wearable device through the short-range wireless communication module to control the wearable device or forward the data of the wearable device.

[0016] In one embodiment, the short-range wireless communication module may include: a Bluetooth module.

[0017] Compared with other short-range wireless communications, Bluetooth communication has the characteristic of low power consumption, which helps to reduce the power consumption of smart devices for cellular communication through wearable device charging devices.

[0018] In one embodiment, the Bluetooth module supports at least one of classic Bluetooth, low-power Bluetooth, and Bluetooth low-power audio.

[0019] In one embodiment, the short-range wireless communication module includes a WIFI (Wireless Fidelity) module.

[0020] In an embodiment of the present application, the short-range wireless communication module of the wearable device charging apparatus further includes a WIFI module, so that the smart device can access the cellular network through WIFI, thereby expanding the use range of the wearable device charging apparatus.

[0021] In a second aspect, an embodiment of the present application provides a cellular communication system, comprising: a wearable device charging device as described in any one of the first aspect; a smart device, wherein the smart device is connected to the data transmission interface of the wearable device charging device via a data cable; the wearable device charging device is also used to respond to the smart device accessing the data transmission interface, and enable the smart device to indirectly access the cellular network based on the data transmission interface, the processor and the cellular communication module.

[0022] In one embodiment, the cellular communication system further includes: a true wireless headset; and the wearable device charging device is a charging box for the true wireless headset.

[0023] In a third aspect, an embodiment of the present application provides a cellular communication method, which is applied to a processor of a wearable device charging device as described in any one of the first aspects; the cellular communication method includes: in response to the smart device accessing the data transmission interface, forwarding the data of the cellular communication module during the cellular communication process to the smart device based on the data transmission interface and sending the data sent by the smart device to the cellular communication module, so that the smart device can indirectly access the cellular network.

[0025] In one embodiment, the smart device itself is connected to a cellular network; the wearable device charging device is a charging box for a true wireless headset; the true wireless headset and the wearable device charging device are connected via short-range wireless communication; the wearable device charging device receives audio data sent from the smart device via cellular communication, and forwards the audio data to the true wireless headset via the short-range wireless communication module; the method also includes: detecting the remaining power of the power module; when the remaining power is less than a preset threshold and the true wireless headset can be connected to the smart device via short-range wireless communication, controlling the true wireless headset to switch to connecting to the smart device via short-range wireless communication, so that the true wireless headset receives the audio data sent from the smart device via short-range wireless communication.

[0026] In the embodiment of the present application, both the charging box and the smart device can access the cellular network to achieve data transmission between the two through forwarding by the cellular base station. In this case, even if the charging box and the smart device are far apart, they can still communicate with each other, and then forward the data through the short-range wireless communication between the charging box and the true wireless headset. Therefore, the user can still receive audio data and make calls without carrying the smart device. When the distance is close (can be connected through short-range wireless communication), the remaining power can be detected. When the remaining power is less (less than a preset threshold), the true wireless headset and the smart device are controlled to directly transmit data through short-range wireless communication to reduce power consumption.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] First, the present application embodiment provides a wearable device charging device 100. Figure 1 , Figure 1 This is a structural block diagram of a wearable device charging apparatus 100 provided in an embodiment of the present application. The wearable device charging apparatus 100 includes: a data transmission interface 110, a power module 130, a charging module 120, a processor 140 and a cellular communication module 150.

[0036] The data transmission interface 110 is used to connect the power line. The charging module 120 is connected to the data transmission interface 110, and the charging module 120 is also connected to the power module 130. After the data transmission interface 110 is connected to the external power supply through the power line, the charging module 120 can obtain electric energy from the external power supply to charge the power module 130, and the power module 130 can store electric energy. At the same time, the charging module 120 is also used to connect the wearable device 300, and can obtain electric energy from the power module 130 to charge the wearable device 300.

[0037] The data transmission interface 110 , the power module 130 and the charging module 120 may refer to the structures of various existing charging devices or use existing structures, which will not be elaborated here.

[0038] In an embodiment of the present application, the wearable device charging apparatus 100 further includes a processor 140 and a cellular communication module 150, the cellular communication module 150 is connected to the processor 140, and the processor 140 is connected to the data transmission interface 110. The processor 140 may be one or include multiple processors, which is not limited here.

[0039] In this embodiment, the cellular communication module 150 is configured with a SIM card or an eSIM (embedded-SIM, electronic SIM card) for accessing a cellular network for cellular communication. The processor 140 can be used to receive data from the cellular communication module 150 during the cellular communication process, or to send data to the cellular communication module 150.

[0040] At the same time, in an embodiment of the present application, the data transmission interface 110 can be connected to the smart device 200 via a data line, and the processor 140 can respond to the access of the smart device 200 through the data transmission interface 110 by forwarding the data of the cellular communication module 150 during the cellular communication process to the smart device 200 via the data line and sending the data sent by the smart device 200 to the cellular communication module 150, so that the smart device 200 can indirectly access the cellular network and realize cellular communication.

[0041] In this embodiment, the processor 140 and the cellular module in the wearable device charging apparatus 100 can be used as an intermediate device to assist the smart device 200 in implementing the cellular function, so that the smart device 200 can indirectly perform cellular communication based on the processor 140 and the cellular module in the wearable device charging apparatus 100.

[0042] In the embodiment of the present application, the processor 140 is used to forward data in the cellular communication process. In the embodiment of the present application, the data transmission interface 110 includes multiple ports, such as a data transmission port and a charging port. The processor 140 can determine whether the data transmission interface 110 has data line access by detecting whether the data transmission port is connected or whether the corresponding indication signal is received, or configure a corresponding detection circuit at the data transmission interface 110 to detect whether the data transmission interface 110 has data line access, and then generate a corresponding trigger signal to control the data forwarding of the cellular module. The specific procedures of the above process can be implemented using existing programs or existing circuits.

[0043] See also Figure 2 , Figure 2 A first communication relationship diagram provided for an embodiment of the present application. In this embodiment, the data transmission link can be represented as: smart device 200, wearable device charging device 100, cellular base station 500, wherein the wearable device charging device 100 is used as a transfer device, through which the smart device 200 can indirectly access the cellular network for cellular communication in some special cases.

[0044] For example, when the smart device 200 is in arrears, the wearable device charging device 100 can be used to indirectly access the cellular network to handle some urgent matters. For another example, the wearable device charging device 100 is used as a testing tool to test whether the cellular module of the smart device 200 itself or the current cellular communication environment is normal. For another example, a tablet computer or a new mobile phone placed at home may not be equipped with a SIM card. The wearable device charging device 100 can be used to access the cellular network for dial-up calls. The above is only an example. The actual application scenario can be selected by the user according to needs, and will not be expanded here.

[0045] In the embodiment of the present application, the smart device 200 is a mobile phone, a tablet computer, etc. The wearable device 300 can be smart glasses, wireless headphones, a smart watch, a bracelet, etc.

[0046] In one embodiment of the present application, the wearable device 300 may be a true wireless headset, and the wearable device charging device 100 may be a charging box for the true wireless headset. The true wireless headset may be any one of an in-ear headset, a semi-in-ear headset, and an open-ear headset, and is not limited here.

[0047] See also Figure 3 , Figure 3 A schematic diagram of a charging box for a true wireless headset provided in one embodiment of the present application. In this embodiment, the true wireless headset includes a first headset and a second headset (or a left headset and a right headset), and the first headset and the second headset each include a contact for charging, and the contact of the first headset and the second headset is usually arranged at the bottom of each headset (bottom of the ear handle). The charging box includes a first contact 121 and a second contact 122, and the first contact 121 and the second contact 122 are respectively connected to the charging module 120, and the first contact 121 and the second contact 122 are respectively arranged at the bottom of different accommodating cavities in the charging bin, and the accommodating cavities are used to accommodate the first headset and the second headset, and the first contact 121 is configured to contact with the contact of the first headset, and the second contact 122 is configured to contact with the contact of the second headset, thereby charging the first headset and the second headset. The above structure can refer to the existing true wireless charging headset and charging box, and will not be expanded here.

[0048] The size of the true wireless headset is relatively small. For easy storage, the true wireless headset is usually placed in a charging box to reduce the possibility of loss. Therefore, when the user carries the true wireless headset, the user usually carries the charging box corresponding to the true wireless headset together. At the same time, the size of the charging box corresponding to the true wireless headset is also relatively small, which is convenient for carrying. Based on this feature, a processor 140 and a cellular module are set in the charging box of the true wireless headset, which is convenient for users to carry with them, so that when necessary, the wearable device charging device 100 can be taken out to enable the smart device 200 to indirectly access the cellular network.

[0049] There are many types of data transmission interface 110. In the embodiment of the present application, the data transmission interface 110 is a type-c interface.

[0050] At present, the type-c interface has been widely used. The interfaces of various smart devices 200 and various wearable devices 300 usually use the type-c interface. For example, the interface of a mobile phone and the charging interface of a true wireless headset are all type-c interfaces. Therefore, in the embodiment of the present application, the type-c interface is selected as the data transmission interface 110, which has better versatility, can be adapted and connected with more devices, is more convenient to use, and reduces the need for users to carry adapters or adapters.

[0051] In other embodiments of the present application, other types of interfaces may be configured, and the charging port and the data transmission port may not be set in the same interface (ie, two interfaces are set), which is not limited here.

[0052] In an embodiment of the present application, the cellular communication types supported by the cellular communication module 150 include at least one of 2G (2-Generation wireless telephone technology, second generation mobile phone communication technology specifications) communication, 3G (3rd-Generation, third generation mobile communication technology) communication, 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology) communication, and 5G (5th-Generation Mobile Communication Technology, fifth generation mobile communication technology) communication.

[0053] The configuration of the above-mentioned cellular communication module 150 can be configured according to actual needs. For example, if the wearable device charging device 100 is used as a means to access the cellular network in an emergency, when the signal transmission speed is low and the battery life is high, 2G communication or 3G communication with lower power consumption can be configured. If the cellular communication module 150 is used as a device specifically for enabling a smart device 200 without a SIM card to indirectly access the cellular network, when there are certain requirements for the transmission speed, 4G communication or 5G communication can be configured. For another example, some smart devices 200 support limited cellular communication types. For example, some smart devices 200 only support 2G communication, 3G communication and 4G communication, but not 5G communication. Therefore, in order to adapt to more devices, the cellular communication types supported by the cellular communication module 150 can include multiple types of 2G communication, 3G communication, 4G communication and 5G communication.

[0054] Currently, the LTE (Long Term Evolution) protocol in 4G communication is widely used, for example, cat-1, cat-4 and other communication protocols in LTE. Therefore, in the embodiment of the present application, the cellular communication module 150 can at least support the LTE protocol.

[0055] In an embodiment of the present application, the wearable device charging apparatus 100 further includes: a short-range wireless communication module 160 , and the short-range wireless communication module 160 is connected to the processor 140 .

[0056] As mentioned above, the wearable device charging apparatus 100 can be connected to the wearable device 300 through the short-range wireless communication module 160. For example, the true wireless earphone is connected to the charging box through short-range wireless communication.

[0057] See also Figure 4 , Figure 4 A second communication relationship diagram is provided for an embodiment of the present application. In this embodiment, the wearable device charging device 100 can also access the cellular network (i.e., directly access the cellular network), and the smart device 200 can also access the cellular network. Therefore, the smart device 200 and the wearable device charging device 100 can achieve long-distance wireless communication to transmit data through the forwarding of the cellular base station / cell. Furthermore, due to the short-distance wireless communication between the wearable device 300 and the wearable device charging device 100, the audio data (such as music, call data) transmitted by the smart device 200 can be played through the wearable device 300. It should be distinguished from the aforementioned embodiment. In this embodiment, the cellular base station is used as a transfer, while in the aforementioned embodiment, the wearable device charging device 100 is used as a transfer device.

[0058] Exemplarily, in one embodiment, the mobile phone (smart device 200) and the charging box (wearable device charging device 100) are connected to the cellular network at the same time, and the mobile phone can send audio data to the charging box through the cellular network, and the charging box can forward the audio data to the true wireless headset for playback through short-range wireless communication. At the same time, the gestures or voices performed by the user in the true wireless headset can be converted into corresponding instructions and transmitted to the mobile phone through the cellular network, so that the mobile phone performs corresponding actions, such as making calls, switching songs, etc. Therefore, when the user goes to exercise (such as running, fitness, swimming, etc.) or goes out for a short time, he can only carry headphones and charging boxes without carrying a mobile phone, and can listen to music, make calls, etc. In this embodiment, the eSIM card used by the charging box can be the same as the eSIM number of the smart device 200 used by the user.

[0059] In an embodiment of the present application, the short-range wireless communication module 160 may include: a Bluetooth module. On the one hand, a wearable device 300 such as a true wireless headset is usually equipped with a Bluetooth module. Therefore, by configuring a Bluetooth module in the wearable device charging device 100, it is possible to achieve an adaptive connection without configuring other modules in the true wireless headset. On the other hand, Bluetooth has low power consumption, which helps to improve the battery life of the wearable device charging device 100.

[0060] In this embodiment, the Bluetooth module can support at least one Bluetooth protocol among classic Bluetooth, low-power Bluetooth, and Bluetooth low-power audio, and can be configured according to the Bluetooth protocols supported by the wearable device 300 and the smart device 200.

[0061] In some embodiments of the present application, the processor 140 is connected to the short-range wireless communication module 160, and the wearable device charging device 100 can also be connected to the smart device 200 through the short-range wireless communication module 160. The processor 140 can respond to the access of the smart device 200 through the short-range wireless communication module 160, forward the data of the cellular communication module 150 during the cellular communication process to the smart device 200 through the short-range wireless communication module 160, and send the data sent by the smart device 200 to the cellular communication module 150, so that the smart device 200 can indirectly access the cellular network for cellular communication.

[0062] Both the short-range wireless communication module 160 and the data transmission interface 110 can transmit data. Therefore, in the embodiment of the present application, the smart device 200 can also be connected to the wearable device charging device 100 through the short-range wireless communication module 160, and the smart device 200 can indirectly access the cellular network through the forwarding of the short-range wireless communication module 160. Compared with the previous embodiment, the only difference is that the short-range wireless communication module 160 is used here to forward the data of the cellular communication, while the previous content is to forward the data through the data transmission interface 110 and the data line. The communication method in this scenario can be referred to Figure 2 The aforementioned contents related to forwarding through the data transmission interface 110 will not be expanded here.

[0063] In one embodiment of the present application, the short-range wireless communication module 160 may also include a WIFI module, so that the wearable device charging device 100 and the smart device 200 can be connected via WIFI. In this embodiment, the wearable device 300 may also be configured with a WIFI module, and the wearable device 300 and the wearable device charging device 100 are connected via WIFI communication.

[0064] Through the WIFI module, more communication methods can be provided to enable the smart device 200 to communicate with the charging device of the guest device, so that the smart device 200 can indirectly access the cellular network and expand the scope of application.

[0065] Based on the same inventive concept, the embodiment of the present application further provides a cellular communication method, which can be applied to the processor of the wearable device charging apparatus provided in the above embodiment. The cellular communication method includes:

[0066] In response to the smart device accessing the data transmission interface, the data of the cellular communication module in the cellular communication process is forwarded to the smart device based on the data transmission interface, and the data sent by the smart device is sent to the cellular communication module, so that the smart device can indirectly access the cellular network information.

[0067] In one embodiment of the present application, the wearable device charging device 100 includes a short-range wireless communication module 160, and the cellular communication method further includes: in response to short-range wireless communication between the smart device 200, forwarding the data of the cellular communication module 150 during the cellular communication process to the smart device 200 based on the short-range wireless communication module 160 and sending the data sent by the smart device 200 to the cellular communication module 150, so that the smart device 200 can indirectly access the cellular network.

[0068] In one embodiment, the smart device 200 itself accesses the cellular network, that is, the smart device 200 directly accesses the cellular network, and the wearable device charging device 100 is a charging box for a true wireless headset; the true wireless headset and the wearable device charging device 100 are connected via short-range wireless communication; the wearable device charging device 100 receives the audio data sent by the smart device 200 via cellular communication, and forwards the audio data to the true wireless headset via the short-range wireless communication module 160. The cellular communication method also includes: detecting the remaining power of the power module 130; when the remaining power is less than a preset threshold and the true wireless headset can be connected to the smart device 200 via short-range wireless communication, controlling the true wireless headset to switch to connecting to the smart device 200 via short-range wireless communication, so that the true wireless headset receives the audio data sent by the smart device 200 via short-range wireless communication.

[0069] The wearable device charging device 100 can communicate with the smart device 200 over a long distance via a cellular network, and send the audio data sent by the smart device 200 via the cellular network to the true wireless headset for playback. This method allows the user to remotely listen to music played by the mobile phone and make calls even if they do not carry a smart device 200 such as a mobile phone.

[0070] However, the power consumption of forwarding through the cellular network is relatively high, which is not conducive to the battery life of the wearable device 300. Therefore, in an embodiment of the present application, the remaining power of the power module 130 in the wearable device charging device 100 can be detected. When the remaining power is small (less than a preset threshold), if the true wireless headset can be connected to the smart device 200 through short-range wireless communication, the true wireless headset is controlled to switch to connecting to the smart device 200 through short-range wireless communication to reduce power consumption and improve battery life.

[0071] Based on the same inventive concept, the present application embodiment further provides a cellular communication system 400, see Figure 5, Figure 5 A cellular communication system 400 is provided in an embodiment of the present application. The cellular communication system 400 includes: a wearable device charging apparatus 100 and a smart device 200.

[0072] In an embodiment of the present application, the smart device 200 can be connected to the data transmission interface 110 of the wearable device charging device 100 via a data line. The wearable device charging device 100 is further configured to enable the smart device 200 to access the cellular network for cellular communication based on the data transmission interface 110, the processor 140 and the cellular communication module 150 in response to the smart device 200 accessing the data transmission interface 110.

[0073] In another embodiment of the present application, the smart device 200 itself accesses the cellular network, the wearable device charging device 100 accesses the cellular network, and the smart device 200 and the wearable device charging device 100 are communicated and connected through the cellular network to transmit data through the cellular network.
