Description

Automatic connection switching method and device for wireless keyboard Technical Field The invention relates to the technical field of wireless keyboards, in particular to a method and a device for automatically switching connection of a wireless keyboard. Background With the rapid development of wireless communication technology and the increasing demand of mobile office, wireless keyboards as an important component of computer peripheral devices have been widely used in various usage scenarios such as home office, mobile office and multi-device collaborative work. Existing wireless keyboards typically support multiple connection modes, including mainly a 2.4G wireless connection mode and a bluetooth connection mode. The 2.4G wireless connection mode establishes connection with the computer equipment through the special wireless receiver, has the advantages of low transmission delay, high response speed and the like, is suitable for desktop fixed office scenes with high requirements on input precision and response speed, supports wireless connection with various mobile equipment such as mobile phones and tablets, has the characteristics of strong portability, good compatibility and the like, and is suitable for mobile office and multi-equipment switching use scenes. However, existing wireless keyboards often require the user to manually switch between different modes of connection. Specifically, the user needs to switch between different connection modes by means of a physical switch or a combination key, or needs to manually select a corresponding connection device in the system setting. The manual switching mode is complex in operation, increases the operation burden of a user, and easily influences the use experience and office efficiency of the user when frequently switching use scenes. Especially in the scene of alternately using home office and mobile office, the user needs to repeatedly switch between 2.4G connection and Bluetooth connection, and the defect of manual operation is particularly obvious. In recent years, wireless charging technology has been widely used and rapidly developed in the consumer electronics field. Wireless keyboard products supporting wireless charging function also gradually enter the market, and the problem of convenience that the traditional wireless keyboard needs to be charged or replaced by a wired mode is solved. For example, chinese patent CN201620840802.8 discloses a "bluetooth keyboard that charges wirelessly", and this technique has realized the wireless function of charging of keyboard through integrating wireless receiving module that charges in the keyboard inside, has promoted user's convenience. However, this prior art mainly focuses on implementation of a charging function, and does not relate to technical contents of automatically recognizing a usage scenario according to a charging state and intelligently switching a connection mode. On the other hand, in order to solve the problem of multi-mode keyboard connection switching, some multi-mode pairing and switching schemes are proposed in the prior art. For example, chinese patent CN120916271a discloses a "keyboard multimode pairing method", which mainly implements switching between different connection modes through preset combination key operations. Although this approach simplifies the operational flow of connection switching to some extent, it is still inherently dependent on manual triggering and active selection by the user, lacking automatic recognition and intelligent decision making capabilities based on usage scenarios. The user still needs to actively judge and execute the switching operation according to the self use scene, and the real intelligent and noninductive switching cannot be realized. In addition, some scene recognition schemes based on sensor detection are also proposed in the prior art, for example, the movement state of the keyboard is detected through an acceleration sensor, or the distance relation between the keyboard and the device is detected through a proximity sensor. However, these schemes require additional hardware sensor modules, which not only increase the cost and complexity of the product, but also the detection accuracy and reliability of the sensor are susceptible to environmental factors, and there is a limit in practical application. In summary, the prior art has the following technical problems that the traditional wireless keyboard needs to manually switch the connection mode, is complex in operation and affects user experience, the traditional wireless charging keyboard only focuses on realization of a charging function, and does not take a charging state as a judging basis for scene recognition and intelligent switching, the traditional multimode switching technology depends on manual operation of a user and lacks automatic and intelligent scene recognition capability, and the scheme based on sensor detection increases hardware cost and system complexity.
