The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application provides a placement box, please refer to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of the placement box and a wearable device provided in the embodiment of the present application, and fig. 2 is a structural schematic diagram of the placement box provided in the embodiment of the present application. The placing case 20 includes a charging section 220 and a communication section 240. The charging section 220 is used to charge the wearable device 30. The communication unit 240 is used for communicating with the wearable device 30. Wherein, when the communication part 240 receives the first information transmitted by the wearable device 30, the charging part 220 is controlled to charge the wearable device 30, and when the communication part 240 does not receive the first information transmitted by the wearable device 30, the charging part 220 is controlled not to charge the wearable device 30.

The placement box 20 can be used not only to place the wearable device 30, but also to charge the wearable device 30. Before charging the wearable device 30, whether the first information transmitted by the wearable device 30 is received through the communication part 240 is detected, if the first information is received, the wearable device 30 is normally charged, and if the first information is not received, the wearable device 30 is not charged, so that the wearable device 30 which is not adapted or other devices which are not adapted can be prevented from being charged, the communication part or the devices which are not adapted are prevented from being damaged, charging safety is guaranteed, and the charging risk is reduced.

Referring to fig. 3, fig. 3 is a schematic structural view of a charging portion and a communication portion of the storage box shown in fig. 1. The charging part 220 may include at least two first metal posts 222, and the communication part 240 may include a second metal post 242. The first metal post 222 is electrically connected to the charging interface of the wearable device 30, and the second metal post 242 is electrically connected to the communication interface of the wearable device 30.

The placing box 20 can charge the wearable device 30 at least by 2 connection pins, that is, the charging function can be realized by the positive and negative electrodes of the battery connected to the wearable device 30. Therefore, the charging portion 220 of the placing box 20 may include 2 first metal posts 222, the charging interface of the wearable device 30 correspondingly includes 2 charging pins, and the charging function of the wearable device 30 is realized through the 2 first metal posts 222 and the 2 charging pins. In addition, the first signal received by the placement box 20 from the wearable device 30 can be realized by at least 1 communication pin, and therefore, the communication part 240 of the placement box 20 can include 1 second metal post 242, and the first signal transmitted by the wearable device 30 is received by the second metal post 242. The first signal may be a preset pulse signal or a signal of a specific level. For example, the first signal may be a 500 millisecond (ms) cycle, normally high, low pulse with a pulse width of 200 microns (us) per cycle. The first signal may also be a 5V or 3V or 0V level signal. Here, the present embodiment does not limit the specific type of the first signal as long as the first signal can make the placing box 20 recognize the wearable device 30 as the authorized device.

A first space is formed between two first metal pillars 222, a second space is formed between the second metal pillar 242 and the adjacent first metal pillars 222, and the second space is not equal to the first space. If the first metal posts 222 and the second metal posts 242 are equally spaced, there is a risk that the first metal posts 222 and the second metal posts 242 are connected, resulting in a short circuit or malfunction of signals. In the embodiment, because the distance between the two first metal posts 222 and the second metal post 242 is different, the charging interface and the communication interface of the wearable device 30 can be prevented from being mistakenly connected, and the problem of signal short circuit or abnormal function caused by the wrong connection can be prevented.

It is understood that the number of the first metal posts 222 of the communication part may be set to 2 or more as necessary. For example, in order to better charge the wearable device 30, the communication part may include more than 2 first metal posts 222, and the first metal posts 222 may also be connected to the whole of the placement box 20, or provide signals of different voltages, or implement multi-path fast charging, etc.

The number of the second metal posts 242 of the communication part may be set as needed. For example, the number of the second metal posts 242 may be 2 to implement IIC communication, or more second metals may be used to implement other communication methods or multiple communication methods at the same time.

It should be noted that the first metal pillar 222 and the second metal pillar 242 may be protruding cylindrical conductive metals, and may also be Pogo pins (Pogo pins), and the tops of the Pogo pins have certain elasticity, so as to be electrically connected to the charging interface of the wearable device 30 conveniently. The charging interface of the wearable device 30 may be a contact. The communication part and the charging interface can be connected through magnetism, so that the alignment and the connection can be performed quickly and accurately.

Referring to fig. 4, fig. 4 is a schematic view of a portion of the storage box shown in fig. 1. The placing case 20 may further include a limiting portion 260, and the limiting portion 260 is used for limiting the position of the wearable device 30 so as to align the charging portion 220 with the charging interface of the wearable device 30. Illustratively, the placement box 20 has a protrusion therein, and the wearable device 30 has a groove corresponding to the protrusion, and the protrusion and the groove are cooperatively disposed, and it can also be understood that the wearable device 30 can be mated with the protrusion only when the placement box 20 is placed in a specific manner, so that the charging interface of the wearable device 30 is correspondingly connected with the communication portion of the placement box 20, the communication interface of the wearable device 30 is correspondingly connected with the communication portion of the placement box 20, and the communication portion of the placement box 20 are prevented from being mistakenly connected with the charging interface and the communication interface of the wearable device 30, and the problem of signal short circuit or abnormal function caused by the mistaken connection is prevented. It can be understood that, since the placing case 20 is provided with the limiting portion 260, the first metal posts 222 of the communication portion and the second metal posts 242 of the communication portion may be equally spaced, i.e., a plurality of the first metal posts 222 and the second metal posts 242 may be equally spaced.

Referring to fig. 5, fig. 5 is a schematic view of a second structure of a storage box and a wearable device according to an embodiment of the present disclosure. The placing box 20 further includes a power management module 270 and a control switch 280, the power management module 270 is connected to the charging part 220 through the control switch 280; when the communication part 240 receives the first information transmitted by the wearable device 30, the control switch 280 is turned on to communicate the power management module 270 with the charging part 220; when the communication part 240 does not receive the first information transmitted from the wearable device 30, the control switch 280 is turned off to disconnect the power management module 270 from the charging part 220.

The connection and disconnection between the power management module 270 and the charging part 220 may be achieved by controlling the switch 280. Specifically, when the placing box 20 receives the first information, it indicates that the placed wearable device 30 is an authorized device, and the control switch 280 is turned on, so that the power management module 270 is communicated with the charging unit 220, that is, the power management module 270 is communicated with the charging interface of the wearable device 30, thereby charging the wearable device 30. When the placing box 20 does not receive the first information, it indicates that the placed wearable device 30 is an unauthorized device or does not need to be charged, the control switch 280 is turned off, that is, the communication part has no charging signal, and the wearable device 30 cannot be charged, so as to prevent the communication part from being burned out or the wearable device 30 from being damaged due to charging the wearable device 30 which is not adapted to the wearable device.

The authorized devices are devices that mate with the placement box 20, such as charging voltage mating, charging connection mating, and the like. Unauthorized devices or non-compliant wearable devices 30 may not match charging voltages, not match charging connections, etc. For example, the communication portion of the storage case 20 is a metal post, and the charging interface not adapted to the wearable device 30 is a USB interface. For another example, the pin arrangement order of the communication section of the set cassette 20 is different from the pin arrangement order of the charging interface of the unauthorized device.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a third placement box and a wearable device according to an embodiment of the present application. The placement box 20 further includes a control chip 290, and the communication unit and the control switch 280 are connected to the control chip 290, the control switch 280 is turned on when the control chip 290 recognizes the first information transmitted from the wearable device 30 through the communication unit, and the control switch 280 is turned off when the control chip 290 does not recognize the first information transmitted from the wearable device 30 through the communication unit.

The control chip 290 of the placement box 20 may be used to determine whether the first information transmitted by the wearable device 30 is received. Illustratively, the control chip may be a watchdog chip (IC). The VDD of the control chip is a power supply port, and the power supply voltage can be 3V. The GPIO _1 of the control chip is a feeding dog input signal (i.e., a first signal), and the first signal may be "normal high level, 500ms one period, one low level pulse per period, and 200 us" pulse width, and the first signal is provided by the wearable device. GPIO _4 of the control chip is an output signal, and outputs high level when a dog feeding input signal is detected; when the feeding dog input signal output is not detected to be low level for 2 continuous periods. The output signal is connected to the control switch, and when the output signal is at a high level, the control switch is switched on; when the output signal is at low level, the control switch is turned off. When the control switch is switched on, the wearable equipment is charged by the placing box; when the switch is off, the placing box does not charge the wearable device.

It will be appreciated that the feed dog input signal may be output by a processor or other IC charged by the wearable device, the output signal matching the compliance requirements of the watchdog chip. Therefore, the parameters of the feed dog input signal need to be written into the watchdog chip in advance.

In this embodiment, the control chip can go into the box and detect in addition to carrying out, and certain security performance still does not charge with the interface contact that charges of wearable equipment in the portion of charging, still needs the first signal that the communication portion received wearable equipment just to charge, has improved security performance.

Referring to fig. 7, fig. 7 is a schematic diagram of a fourth structure of a placing box and a wearable device according to an embodiment of the present application. The power management module 270 may be configured to connect to an external power source, which may be 110V commercial power or 220V commercial power. The power management module 270 may be directly connected to the utility power, or may be connected to the utility power through the adapter 230. The placement box 20 may include a first battery 210, and the power management module 270 may convert an external power source into a suitable voltage to charge the first battery 210 or the wearable device 30. Wherein, when the power management module 270 is connected to an external power source, the power management module 270 is configured to charge the first battery 210 and/or the wearable device 30 with the external power source. Specifically, when the power management module 270 is connected to an external power source and the placement box 20 receives the first signal from the wearable device 30, the power management module 270 charges the wearable device 30 by using the external power source, and of course, the wearable device 30 and the first battery 210 may be charged at the same time. When the power management module 270 is connected to an external power source and the placing box 20 does not receive the first signal of the wearable device 30, the power management module 270 supplies the external power source to the first battery 210.

When the power management module 270 is not connected to an external power source, the wearable device 30 may be charged using the first battery 210 inside the placement box 20. For example, when the user goes outdoors or outdoors, the placement box 20 may charge the wearable device 30 using the first battery 210, and the placement box 20 may not only accommodate and protect the wearable device 30, but also charge the wearable device 30, thereby improving the endurance of the wearable device 30.

It will be appreciated that the placement kit may also be provided without the first battery, by converting an external power source to a suitable voltage and charging the wearable device.

It should be noted that the placing box and the wearable device can be in direct contact to realize electrical connection, so as to realize charging and communication, and the placing box and the wearable device can also be in wireless charging and/or wireless communication. Illustratively, the communication portion includes a wireless communication module through which the placement box wirelessly communicates with the wearable device. Such as via bluetooth communication, wifi communication, etc. In another example, the communication unit includes a wireless charging module that wirelessly charges the wearable device. If wireless charging module includes wireless transmitting coil, wireless transmitting coil is magnetic energy transmission away with electric energy conversion, and wearable equipment's wireless receiving coil receives this magnetic energy to convert this magnetic energy into the electric energy, thereby realize wireless charging function. In another example, the communication portion of the storage box includes a wireless charging module, and the communication portion includes a wireless communication module, and the structures of the wireless charging module and the wireless communication module are referred to the above embodiments and are not described herein again.

Fig. 8 is a schematic structural diagram of a wearable device according to an embodiment of the present application, referring to fig. 8 in combination with fig. 1 to 7, where fig. 8 is a schematic structural diagram of the wearable device according to an embodiment of the present application. The structure of the wearable device 30 may be the structure of the wearable device 30 in any of the above embodiments, and will not be described herein.

In some embodiments, please refer to fig. 9, and fig. 9 is a first structural diagram of a wearable device and a power supply device according to an embodiment of the present disclosure. Wearable device 30 may include charging interface 320, second battery 340, and communication interface 360. Charging interface 320 is configured to connect to power supply 40. The second battery 340 is electrically connected to the charging interface 320. The communication interface 360 is used for communication with the power supply apparatus 40. When the communication interface 360 receives the second information transmitted by the power supply apparatus 40, the communication between the charging interface 320 and the second battery 340 is controlled, so that the power supply apparatus 40 charges the second battery 340, and when the communication interface 360 does not receive the second information transmitted by the power supply apparatus 40, the communication between the charging interface 320 and the second battery 340 is controlled.

Before the wearable device 30 is charged, whether the second information transmitted by the power supply device 40 is received through the communication interface 360 is detected, if the second information is received, the second battery 340 is normally charged, and if the second information is not received, the second battery 340 is not charged, so that the power supply device 40 which is not adapted can be prevented from charging the wearable device 30, the charging interface 320 or the power supply device 40 which is not adapted is prevented from being damaged, the charging safety is ensured, and the charging risk is reduced. The power supply device 40 may be an adapter, a computer, a charger, a mobile phone with a charging function, a tablet computer, or other power supply device 40, and the charging device may also be a specially-made device, such as the placement box in any of the above embodiments, as shown in fig. 10.

With continued reference to fig. 10, the second signal is sent from the placement box 20, and the wearable device 30 can be identified by a chip in the functional module, or by a dedicated chip identification, such as a watchdog chip. The placing box 20 only needs to be provided with a circuit for sending the second signal, the circuit of the placing box 20 is simple, and a special chip identification signal and a control circuit do not need to be arranged.

The wearable device 30 further comprises a processor 380, the communication interface 360 is connected with pins of the processor 380, and the processor 380 provides a first level to the pins; when the communication interface 360 is connected to a communication section of a power supply device such as the set box 20, the communication section has a second level which is not equal to the first level; when the processor 380 recognizes that the pin changes from the first level to the second level, it is determined that the communication interface 360 receives the second information transmitted from the power supply apparatus, such as the placing box 20.

For example, communication interface 360 may be connected to processor 380 of wearable device 30 via an IO port, with the IO port of processor 380 defaulting to high, e.g., 3V. If the communication interface 360 is not connected to the communication part 240 of the placement box 20, the IO port voltage is not pulled low, which indicates that the wearable device 30 is not placed in the placement box 20 and the second battery 340 is not charged. If the communication interface 360 is connected to the communication unit 240 of the placement box 20, the communication unit 240 is grounded or at a low level, such as 1V, and the communication unit 240 pulls down the voltage of the IO port, the voltage of the IO port is pulled down, which indicates that the wearable device 30 is placed in the placement box 20 and starts to charge the second battery 340.

The processor 390 may control the connection and disconnection between the second battery 340 and the charging interface 320 through the switch 330. It can be understood that the wearable device may also control the second battery to be connected to and disconnected from the charging interface in other manners, for example, the second battery is connected to the charging interface through the charging circuit, and the processor controls the charging circuit to be turned on or off to realize the connection and disconnection between the second battery and the charging interface.
