The lens box comprises a shell 1, wherein the shell 1 comprises a sliding groove 2, a lens groove 3 and a sensing switch 4 are embedded in the sliding groove 2, and the lens groove 3 and the sensing switch 4 are adjacently arranged;

A push cover 5 is arranged in the sliding groove 2, and the push cover 5 is used for sliding along the sliding groove 2 so as to shield the lens groove 3 or the inductive switch 4.

Fig. 1 is a schematic view of the push cover 5 sliding over the induction switch 4, and fig. 2 is a schematic view of the push cover 5 sliding over the lens slot 3.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a push cap 5 according to the present embodiment.

The push cover 5 is provided with an embedded groove 7, the embedded groove 7 can be arranged on the front surface of the push cover 5 or on the back surface of the push cover 5, fig. 3 shows a scene that the embedded groove 7 is arranged on the back surface of the push cover 5, and the PCBA assembly 9 is embedded in the embedded groove 7.

Referring to fig. 4, fig. 4 is a schematic circuit structure diagram of a PCBA assembly according to the present embodiment.

The PCBA assembly 9 comprises an NFC chip 6, a battery 10, a high-frequency triode 13, an NFC antenna 14, a control switch 15, a Hall switch 16 and a touch switch, wherein the touch switch comprises a touch chip 11 and a touch area 12.

Specifically, the NFC antenna 14 is connected to the control switch 15, the control switch 15 is connected to the NFC chip 6, the control switch 15 is further connected to the touch chip 11, the touch chip 11 is connected to the touch area 12, the hall switch 16 and the high-frequency triode 13, the touch chip 11 and the high-frequency triode 13 are both connected to the battery 10, and the battery 10 is connected to the hall switch 16.

When the push cover 5 slides to the position above the induction switch 4, i.e. the position shown in fig. 1, the hall switch 16 is close to the induction switch 4 and is opened, and the current of the battery 10 passes through the hall switch 16 and forms a power supply loop with the touch switch, so that the touch switch works.

Specifically, the inductive switch 4 includes a magnet for generating a magnetic field signal to turn on the hall switch 16 when it is close to the magnet.

When the touch switch detects a touch action, a corresponding touch signal is generated and sent to the control switch 15, the control switch 15 is turned on according to the touch signal, so that the NFC chip 6 is turned on, and the NFC chip 6 sends a pre-stored control instruction to the electronic device.

Various functions of the mobile phone, such as photographing, video shooting and sweeping of various apps, are required to use a camera of the mobile phone, and a user can start the camera of the mobile phone through a touch signal, so that various functions are completed.

For example: the photographing function is turned on by one touch, the photographing video function is turned on by two touches, and so on. NFC chips generally store only one instruction and require advanced entry into the NFC chip. Specifically, the push cover can be pushed to the upper part of the induction switch, the touch area is touched, and the touch switch sends corresponding signals to the control switch, so that the control switch is turned on, the NFC chip is further turned on, and at the moment, an instruction can be input to the NFC chip through external equipment and stored. For example, the instruction corresponding to the photographing function is recorded, or the instruction corresponding to the photographed video is recorded.

When the control switch 15 is turned on, the NFC chip 6 is activated, and a pre-stored control instruction may be sent to the electronic device, so as to control the electronic device to perform a corresponding action, such as turning on a camera, etc. If no touch action is received or the touch action is not a preset action, the control switch 15 is not turned on, and the NFC chip 6 does not send a pre-stored control instruction.

Therefore, the push cover 5 is used as a switch of the NCF chip, when the push cover 5 slides to the upper part of the induction switch 4, the touch switch is just turned on, and a user can conduct the control switch 15 through the touch action, so that the NFC chip 6 is activated, the camera is not shielded at the moment, and the combination of the mobile phone camera and the NFC function is more convenient for the user. Moreover, the user only slides the push cover 5 above the inductive switch 4, then the control switch 15 is turned on through the touch action, so that the NFC function of the NFC chip 6 can be opened, and then the NFC chip 6 can send out a pre-stored control instruction, so that the false NFC control instruction can be prevented from being sent out due to false touch.

When the push cover 5 slides to the position above the lens slot 3, i.e. the position shown in fig. 2, the hall switch 16 is far away from the inductive switch 4 and is turned off, the battery 10 is turned off to supply power to the touch switch, so that the touch switch stops working, and at this time, a user cannot generate a touch signal by touching or clicking the touch switch, so that the control switch 15 cannot be turned on and activate the NFC chip 6.

According to the embodiment, the lens groove 3 and the inductive switch 4 are embedded in the sliding groove 2 of the shell 1, the push cover 5 is arranged in the sliding groove 2, the touch function of the touch switch can be opened by moving the push cover 5 to the upper side of the inductive switch 4, then a corresponding instruction can be sent to the mobile phone through the touch switch on the push cover 5, and when the NFC function is required to be closed, only the push cover 5 is required to be slid to the upper side of the lens groove 3, and the function of protecting the camera of the mobile phone is also achieved.

In one embodiment, the protective case further comprises: the NFC antenna 14 is connected with the NFC chip 6 through the control switch 15, and the NFC antenna 14 is used for being connected with the NFC chip 6 through the control switch 15 after the control switch 15 is turned on and sending a control instruction prestored in the NFC chip 6 to the electronic device.

The NFC antenna 14 is used as an element for sending a control instruction, when the control switch 15 receives and conducts a touch signal, the NFC antenna 14 is connected with the NFC chip 6 through the control switch 15, the NFC chip 6 sends a pre-stored control instruction to the electronic device through the NFC antenna 14, if the control switch 15 does not receive and conducts the touch signal, and the NFC chip 6 cannot send the pre-stored control instruction to the electronic device through the NFC chip 6.

In one embodiment, the touch switch includes a touch area 12 and a touch chip 11, where the touch area 12 is connected to the touch chip 11, the touch area 12 is used to collect touch actions and send the touch actions to the touch chip 11, and the touch chip 11 is used to generate different touch signals according to different touch actions.

Specifically, the touch chip 11 further includes a memory and a processor, where the memory is configured to store touch signals corresponding to different touch actions, and the processor is configured to send out corresponding touch signals according to the touch actions.

For example: determining touch information corresponding to one touch action as a camera function of the mobile phone, determining touch information corresponding to two continuous touch actions as a camera function of the mobile phone, determining touch information corresponding to three continuous touch actions as a sweep function of the mobile phone, and the like. The user can select one of the touch actions and the corresponding touch information according to his own preference, and then store the touch action and the corresponding touch information in the memory. In general, there is only one touch signal stored in the memory, and this touch signal is used to cause the control switch to be turned on.

For example: if the touch signal stored in the memory is two continuous touches, the user needs to touch the touch area twice continuously to enable the processor to send out the touch signal, so that the control switch is turned on, and further the NFC chip sends out the stored control instruction. If the touch signal needs to be changed, a new touch signal needs to be changed or re-entered into the memory.

The user clicks or touches the touch area 12 twice, the processor finds the corresponding target touch information from the storage area according to the clicking or touch operation of the user, and sends the target touch information to the control switch, the control switch is turned on according to the touch information, so that the NFC chip is connected with the NFC antenna, the NFC chip sends a pre-stored control instruction to the electronic device through the NFC chip, and the electronic device opens the function corresponding to the control instruction. If the clicking or touching operation of the user is inaccurate, the target touch information cannot be found from the memory, and the control switch cannot be turned on. The user may also select other ways to activate the control switch based on his own habits.

In this embodiment, different touch signals are generated through different touch or click operations of the user on the touch area 12, so as to control the electronic device to execute actions corresponding to the touch signals, and realize signal interaction between the mobile phone protective shell and the electronic device.

In one embodiment, the control switch 15 further includes a control unit, where the control unit is configured to control the control switch 15 to be turned on when a first touch signal is received, and control the control switch 15 to be turned off when a second touch signal is received.

The first touch signal may be a signal emitted by two consecutive touches, and the second touch signal is a signal emitted by two consecutive touches. That is, when the user touches the touch area 12 twice continuously for the first time, the touch chip 11 sends a first touch signal to the control switch 15 according to the touch action, and the control switch 15 is turned on after receiving the first touch signal, so that the NFC antenna 14 and the NFC chip 6 are connected, and the NFC chip 6 can send a pre-stored control instruction to the electronic device through the NFC antenna 14. If the touch action is wrong, such as: when the touch chip 11 is touched three times continuously, the control switch 15 cannot be turned on at the moment when the touch chip 11 cannot send out a correct touch signal, so that the false touch can be prevented from sending out an incorrect control command.

Specifically, the touch signal may be a level signal, such as a high level signal, and when the control switch 15 receives the high level signal, the control switch is turned on, so that the NFC chip 6 is connected to the NFC antenna 14, and the NFC chip 6 sends a pre-stored control instruction to the electronic device through the NFC antenna 14.

In one embodiment, the PCBA assembly further includes a high frequency transistor 13, and the high frequency transistor 13 is connected to the touch chip 11, the hall switch 16, and the battery 10, respectively, for controlling the switching of the touch chip 11.

In one embodiment, the push cap 5 further includes a friction part 8, and the friction part 8 is provided with a protrusion for increasing the friction force of the push cap 5, so that the user slides the friction part 8 to drive the push cap 5 to slide.

Specifically, the shape of the protrusion may be a dot shape or a stripe shape, so that the user can more conveniently move the push cover 5, thereby realizing the opening and closing of the hall switch.
