[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0023] The following embodiments are divided for the convenience of description and shall not constitute any limitation on the specific implementation of the present invention. The embodiments may be combined with each other and referenced to each other without contradiction.

[0024] An embodiment of the present invention relates to a wireless linkage method, which is applied to a battery pack integrated with a wireless module, and the method includes: in response to a switching instruction, the battery pack switches between a transmitting end main state and a receiving end main state; when the battery pack is in the transmitting end main state, the battery pack in the transmitting end main state sends a communication signal to the outside to indicate the working state of the battery pack in the receiving end main state; when the battery pack is in the receiving end main state, the battery pack in the receiving end main state receives the communication signal sent by the battery pack in the transmitting end main state, and adjusts its own working state according to the communication signal.

[0025] Compared with the prior art, the embodiments of the present invention integrate a wireless module in the battery pack, and a switching module is provided in the battery pack to control the battery pack to switch between the transmitting end main state and the receiving end main state. The battery pack in the transmitting end main state sends a communication signal to the outside to indicate the working state of the battery pack in the receiving end main state. The battery pack in the receiving end main state receives the communication signal sent by the battery pack in the transmitting end main state, and adjusts its own working state according to the communication signal to realize the linkage between the devices installed between the battery packs. Wireless connection between products is realized by disassembling and installing the battery pack. The switching module of the battery pack can flexibly adjust the product as a signal transmitter or a signal receiver, realizing the free combination of multiple product linkage.

[0026] The details of the wireless linkage method of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0027] The wireless linkage method in the embodiment of the present invention comprises the following steps:

[0028] Step 101, in response to a switching instruction, the battery pack switches between a transmitting end main state and a receiving end main state.

[0029] Specifically, the detachable external battery pack has a wireless communication function, and a wireless module can be integrated on a control board inside the battery pack. The wireless module can be a Bluetooth wireless module.

[0030] A switching switch is provided on the battery pack housing. The switching switch may be a mechanical rebound button, which can be pressed to switch between the transmitting end main body state and the receiving end main body state. The switching switch may also be a sliding switch, which can be pushed to slide the button to different contact points to switch between the transmitting end main body state and the receiving end main body state. The switching instruction is issued by triggering the switching switch.

[0031] In addition, an indicator light is provided on the battery pack housing, and the change in the color of the indicator light determines whether the battery pack is switched to the transmitting end main body state or the receiving end main body state.

[0032] Step 102, when the battery pack is in the transmitting end main state, the battery pack in the transmitting end main state sends a communication signal to the outside to indicate the working state of the battery pack in the receiving end main state.

[0033] In addition, when the battery pack is in the transmitter main state, the battery pack in the transmitter main state receives the communication signal sent by other battery packs in the transmitter main state, and adjusts its own working state according to the communication signal. The battery pack in the transmitter main state can serve as a signal receiving end to receive the communication signal sent by other battery packs in the transmitter main state, that is, when two battery packs in the transmitter main state are paired and connected, they can receive each other's communication signals and realize two-way control between the battery packs.

[0034] Step 103, when the battery pack is in the receiving end main state, the battery pack in the receiving end main state receives the communication signal sent by the battery pack in the transmitting end main state, and adjusts its own working state according to the communication signal.

[0035] Specifically, when wireless linkage is performed between multiple products, at least two products are included that are equipped with the above-mentioned battery packs, and the battery pack of at least one of the products is in the transmitting end main body state, and the battery packs of other products can be in the transmitting end main body state or the receiving end main body state. Multiple products are paired through the wireless module in the battery pack. After the pairing is successful, the product where the battery pack in the transmitting end main body state is located sends a specific current signal to the battery pack to instruct the battery pack to perform a pairing operation. After the battery pack in the transmitting end main body state detects the current signal, it sends a communication signal to the outside. After the battery pack in the receiving end main body state receives the communication signal, the receiving end battery pack instructs the receiving end device to perform linkage by releasing current. For example, multiple products need to be started or stopped synchronously. The communication signal sent by the battery pack in the transmitting end main body state includes instructions to instruct other devices to start or stop. After receiving the communication signal, the other battery packs instruct the receiving end device to start or stop by releasing current.

[0036] In addition, when the battery pack is in the transmitting end main body state, it is determined whether the battery pack in the transmitting end main body state sends a communication signal externally according to the current change of the battery pack.

[0037] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0038] The embodiment of the present invention also relates to a battery pack 20, such as Figure 2 As shown, it includes: a switching module 21, which is used to send a switching instruction to control the battery pack to switch between the transmitting end main state and the receiving end main state; when the battery pack is in the transmitting end main state, the wireless module 22 is used to send a communication signal to the outside to indicate the working state of the battery pack in the receiving end main state; when the battery pack is in the receiving end main state, the wireless module 22 is used to receive the communication signal sent by the battery pack in the transmitting end main state, and adjust its own working state according to the communication signal.

[0039] The battery pack housing is also provided with a pairing switch for opening or closing the pairing connection with other battery packs. The pairing switch may be a mechanical rebound button, and the signal pairing between battery packs is performed by long pressing the matching switch button.

[0040] The battery pack housing is also provided with a power switch for turning on or off the power supply of the battery pack. The power switch and the pairing switch can be integrated into the same switch button, and the control functions can be distinguished by different operation modes. For example, the short press and long press operations represent the power supply and pairing connection functions respectively.

[0041] In addition, the battery pack also includes an indicator light for indicating by color whether the battery pack is in a transmitter main body state or a receiver main body state, and / or for indicating the pairing state of the battery pack by a light state. When the indicator light of the battery pack displays a different color than the power-on display color, it indicates that the battery pack is in a transmitter main body state or a receiver main body state. And when the indicator light of the battery pack is in a flashing state, the battery pack is in a pairing state. The battery pack is always on, indicating that the battery pack has been successfully paired, etc.

[0042] When the battery pack in this embodiment is in the transmitting end main body state, it can be installed in the device to enable the individual device to have the function of transmitting wireless signals. It can also cooperate with other battery packs to complete the wireless pairing connection to achieve linkage between multiple devices.

[0043] It is not difficult to find that this embodiment is a device embodiment corresponding to the method embodiment, and this embodiment can be implemented in conjunction with the method embodiment. The relevant technical details mentioned in the method embodiment are still valid in this embodiment, and in order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the method embodiment.

[0044] It is worth mentioning that all modules involved in this embodiment are logic modules. In practical applications, a logic unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units. In addition, in order to highlight the innovative part of the present invention, this embodiment does not introduce units that are not closely related to solving the technical problem proposed by the present invention, but this does not mean that there are no other units in this embodiment.

[0045] An embodiment of the present invention relates to a wireless linkage system, comprising: at least two devices equipped with the above-mentioned battery packs, wherein at least one of the battery packs is in a transmitting end main body state.

[0046] like Figure 3 to Figure 4 As shown, among the multiple linkage devices in the wireless linkage system, a device with a transmitter main state battery pack installed (transmitter in the figure) and a device with a receiver main state battery pack installed (receiver in the figure) can be paired, and at this time, the communication signal can only be sent from the transmitter to the receiver in one direction. It can also be composed of a pair of devices with a transmitter main state battery pack installed (transmitter in the figure), and at this time, the communication signal can be transmitted bidirectionally between the transmitters.

[0047] After multiple battery packs are successfully paired, the switching module of each battery pack can be used to control the battery pack to switch between the transmitter main state and the receiver main state, thereby adjusting the communication signal transmission direction between multiple successfully paired devices and improving the flexibility of signal transmission between paired devices.

[0048] After multiple battery packs are successfully paired, if one of the battery packs is detected to be disconnected, the disconnected battery pack will not affect the pairing status of other successfully paired battery packs, and the remaining successfully paired battery packs remain connected. If the disconnected battery pack is the only battery pack in the transmitter main state, it is necessary to adjust the switching module of any of the remaining battery packs to switch the battery pack to the transmitter main state to ensure that there is a device in the wireless linkage system that can send communication signals.

[0049] In addition, after multiple battery packs are successfully paired, if a pairing request from another battery pack is received, the connection of the successfully paired battery pack is disconnected and the pairing operation is performed again.

[0050] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present invention, and that in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention.
