In recent years, wireless charging technology has been developed very rapidly, and the technology enables a user to get rid of a complicated circuit in the charging process, so that the charging process becomes convenient and easy. Terminal equipment such as smart mobile phone not only can wireless charge, can also carry out wireless reverse power supply for some accessories, for example carries out wireless reverse power supply for terminal equipment's protective housing. However, in the related art, when the terminal device assembled in the protective case is placed on the wireless charging transmitting terminal, the wireless charging transmitting terminal cannot charge the terminal device due to the interference of the protective case.
Specifically, the terminal device, the protective shell and the wireless charging transmitting terminal may adopt the same wireless charging protocol, and the protocol is generally divided into several stages of searching, identifying, configuring and transmitting, that is, the power supply terminal and the power receiving terminal search each other at the beginning, identify each other once they search each other, configure after they are identified as transmissible devices, and start to transmit electric energy when the configuration is completed. Therefore, when the terminal equipment and the protective shell are both placed on the wireless charging transmitting terminal, the terminal equipment and the two power receiving terminals of the protective shell are in protocol interaction with the wireless charging transmitting terminal, and the wireless charging transmitting terminal cannot determine which power receiving terminal is the power receiving terminal needing power supply, so that protocol configuration cannot be completed, namely charging cannot be performed.
Based on this, referring to fig. 1, at least one embodiment of the present disclosure provides a protective case 100 of a terminal device 200, where the protective case 100 includes a bottom plate and a side plate, the bottom plate and the side plate form a receiving groove matched with the terminal device 200, and a first coil 101 is disposed in the bottom plate; wherein the first coil 101 is configured to send a first private communication packet to the terminal device 200, and receive electric energy transmitted by the terminal device 200 after the terminal device 200 returns a second private communication packet.
The shape of the accommodation groove of the protective case 100 is matched with the terminal device 200 such as a smart phone, so that the terminal device 200 can be placed in the accommodation groove, thereby realizing protection, function expansion, and the like of the terminal device 200. The upper ends of the side plates of the terminal device 200 may be provided with some inward protrusions, so that the terminal device 200 may be limited when the terminal device 200 is placed in the accommodating groove, and meanwhile, the material of the protective case 100 may have a certain elasticity, so that the terminal device 200 is conveniently placed in and taken out. The protective case 100 also has holes for the camera, speaker, earpiece, keys, etc. of the terminal device 200.
The protective case 100 has at least one power element, such as a flashing light, a direction positioning module, etc., which can be supplied with power received by the first coil. Furthermore, the protection shell 100 may further be provided with a first battery in the bottom plate and/or the side plate, and the first coil 101 is further configured to transmit the electric energy to the first battery, that is, to charge the first battery, and then the first battery supplies power to the power utilization elements, so that the power supply stability of the power utilization elements can be ensured, and the influence of the state of the terminal device is avoided.
The first coil 101 is disposed on the bottom plate, and the second coil 201 of the terminal device 200 is also disposed near the rear case, thereby facilitating wireless electromagnetic induction of the first and second coils 101 and 201. The wireless charging protocol built in the protective housing 100 increases the authentication process of the private communication packet in the original charging protocol, and the reverse charging part in the wireless charging protocol of the terminal device 200 correspondingly increases the authentication process of the private communication packet. Taking the wireless charging protocol formed by the above-mentioned steps of searching, identifying, configuring and transmitting as an example, after the configuration phase is completed, before entering the transmission phase, the authentication process of the private communication packet may be added, that is, the protection shell 100 as the power receiving end sends the first private communication packet, for example, an ASK communication packet through the first coil 101, and after the terminal device 200 as the power supplying end receives the first private communication packet through the second coil 201, the second private communication packet, for example, an FSK communication packet, may be returned to the protection shell 100 according to the pre-built protocol content, and then authentication of the private communication packet is completed, after the private communication packet passes through authentication, thereby establishing an electric energy transmission channel between the terminal device 200 and the protection shell 100, that is, the terminal device 200 charges the first battery of the protection shell through electromagnetic induction between the second coil 201 and the first coil 101.
Because the private communication packet authentication process is not added in the basic wireless charging protocol, the power supply end of the built-in basic wireless charging protocol cannot complete the private communication packet authentication with the protective shell 100, i.e. cannot charge the protective shell 100. Under the scenario that the terminal device 200 and the protective housing 100 are simultaneously placed on the wireless charging transmitting terminal 300, the terminal device 200 and the protective housing 100 all interact with the wireless charging transmitting terminal 300 in a protocol manner, the protective housing 100 cannot be used as a power receiving terminal by the wireless charging transmitting terminal 300 because private communication packet authentication cannot be completed with the wireless charging transmitting terminal 300, a forward charging part in a wireless charging protocol of the terminal device 200 is used as a base protocol content, and the wireless charging transmitting terminal 300 can be used as the power receiving terminal without completing authentication of the private communication packet, so that only the terminal device 200 is the power receiving terminal which can be identified by the wireless charging transmitting terminal 300, namely, the protective housing 100 cannot interfere the power supply process of the wireless charging transmitting terminal 300 to the terminal device 200.
In addition, no electromagnetic induction signal shielding element is provided in the bottom plate of the protective case 100. Generally, the protection case 100 in the related art is provided with an electromagnetic induction signal shielding element such as a nanocrystal, and is disposed on a side of the first coil 101 far away from the accommodating groove, so that leakage of electromagnetic induction signals can be avoided and power transmission efficiency can be improved when the terminal device 200 transmits power to the first coil 101 through the electromagnetic induction signals. In this embodiment, the electromagnetic induction signal shielding element is not disposed in the bottom plate, so that when the terminal device 200 assembled in the protective housing 100 is placed on the wireless charging transmitting terminal 300 for charging, the electromagnetic induction signal shielding element in the protective housing 100 is prevented from blocking electromagnetic induction signals transmitted between the wireless charging transmitting terminal 300 and the terminal device 200, and further, the influence of the protective housing 100 on the wireless charging of the terminal device 200 by the wireless charging transmitting terminal 300 is prevented.
The first coil 101 is disposed in the bottom plate of the protective housing 100 of the terminal device 200 provided by the present disclosure, and the first coil 101 can send a first private communication packet to the terminal device 200, and receive electric energy transmitted by the terminal device 200 after the terminal device 200 returns to a second private communication packet, thereby completing a process of reversely powering the protective housing 100 by the terminal device 200. Because the protective housing 100 and the terminal device 200 are paired through the first private communication packet and the second private communication packet and then perform power transmission, and other wireless charging devices cannot return the second private communication packet to the protective housing 100, so that wireless charging of other wireless charging devices to the protective housing 100 can be avoided, and therefore when the terminal device 200 assembled in the protective housing 100 is placed on the wireless charging transmitting terminal 300 to charge, the wireless charging transmitting terminal 300 cannot return the second private communication packet to the protective housing 100, the protective housing 100 cannot interfere with the wireless charging transmitting terminal 300, and the wireless charging transmitting terminal 300 can charge the terminal device 200 in the above-mentioned scene, thereby facilitating charging of users and improving user experience.
Referring to fig. 1, according to a second aspect of the embodiments of the present disclosure, a terminal device 200 is provided, in which a second coil 201 and a second battery are disposed in the terminal device 200, where the second coil 201 is configured to receive a first private communication packet sent by a protection shell 100 and return the second private communication packet to the protection shell 100 when the terminal device 200 is in a reverse power supply state, and obtain electric energy from the second battery after the protection shell 100 receives the second private communication packet, and transmit the electric energy to the protection shell 100.
In some embodiments of the present disclosure, the second coil 201 is further configured to receive the electric energy transmitted by the wireless charging transmitting terminal 300 through the protective case 100 and transmit the electric energy to the second battery in a state in which the terminal device 200 is in a charging state.
Wherein the terminal device 200 has both a charging and a reverse power supply state. In the charged state, the terminal device 200 serves as a powered end, and performs a forward charging portion, that is, a portion excluding private communication packet authentication, in the wireless charging protocol interaction process; in the reverse power supply state, the terminal device 200 performs a reverse charging section, i.e., a section including private communication packet authentication, as a power supply end in the wireless charging protocol interaction process.
In the reverse power supply process, the terminal device 200 can receive the first private communication packet sent by the protective housing 100, and respond to the first private communication packet to reply to the second private communication packet, thereby completing the authentication of the private communication packet with the protective housing 100, and further establishing an electric energy transmission channel in an electromagnetic induction form with the protective housing 100, that is, charging the first battery of the protective housing 100 through the second coil 201 and the first coil 101. The reverse charging process is described in more detail in the first aspect, and will not be repeated here.
In the forward charging process, the terminal device 200 can complete protocol authentication with the wireless charging transmitting terminal 300, so that an electromagnetic induction type power transmission channel is established with the wireless charging transmitting terminal 300, and the second coil 201 receives power transmitted by the wireless charging transmitting terminal 300, so that charging of the terminal device 200 is realized. The implementation of this procedure is mainly due to the exclusion of the interference of the protective case 100, and the specific procedure has been described in detail in the first aspect, and will not be repeated here.
In addition, the terminal device 200 may have an electromagnetic induction signal shielding element such as the nanocrystal 202 therein, and the electromagnetic induction signal shielding element may be disposed inside the second coil 201, so that signal leakage may be avoided when the second coil 201 performs power transmission through an electromagnetic induction signal.
Referring to fig. 1, according to a third aspect of the embodiments of the present disclosure, a wireless charging transmitting terminal 300 is provided, where the wireless charging transmitting terminal 300 has a third coil 301, and the third coil 301 is configured to not respond to a first private communication packet sent by a protection shell 100 and transmit electric energy to the terminal device 200 when the terminal device 200 is in a charged state.
The wireless charging protocol in the wireless charging transmitting terminal 300 is a base protocol, and does not include a portion for authenticating the private communication packet, that is, does not reply after receiving the first private communication packet sent by the protecting shell 100, and cannot identify and respond to the first private communication packet, so that the protecting shell 100 cannot serve as a power receiving terminal of the wireless charging transmitting terminal 300, and therefore cannot interfere with charging of the terminal device 200 by the wireless charging transmitting terminal 300.
In addition, the wireless charging transmitting terminal 300 may have an electromagnetic induction signal shielding element such as a nanocrystal 302 therein, and the electromagnetic induction signal shielding element may be disposed inside the third coil 301, so that signal leakage may be avoided when the third coil 301 performs power transmission through electromagnetic induction signals.
According to a fourth aspect of embodiments of the present disclosure, there is provided a charging method applied to a protective case of a terminal device, the protective case having a first coil; referring to fig. 2, a flow of the method is shown, which includes steps S201 to S203.
