Description

Technical Field

[0001] The present invention relates to the technical field of audio-visual electronic products, and in particular to a modular Bluetooth headset charging box and a Bluetooth headset switching method. Background Art

[0002] The Bluetooth headset charging box is a headset peripheral product mainly used to charge wireless headsets. Due to the small size of Bluetooth headsets and the limitations of battery energy storage technology, split Bluetooth headsets currently have a natural disadvantage in terms of battery life. The charging box can provide additional power for Bluetooth headsets, thereby extending the battery life of Bluetooth headsets and meeting the needs of users for all-day use.

[0003] At present, common Bluetooth headset charging boxes are usually used to charge a pair of headphones. When the battery of the pair of headphones runs out, it needs to be reinserted into the charging box to recharge before it can be used again, that is, the user needs to wait for a recharging process. If two or more pairs of headphones need to be used in a cycle, a headset box needs to be purchased repeatedly, and the switching control between multiple pairs of headphones cannot be effectively handled. Summary of the invention

[0004] The purpose of the present invention is to provide a modular Bluetooth headset charging box and a Bluetooth headset switching method, which are helpful to solve the above-mentioned technical problems.

[0005] The present invention is achieved in that:

[0006] A modular Bluetooth headset charging box comprises a base and a main card holder; a main card slot is arranged on the upper surface of the base, the main card holder and the main card slot are matched with each other and can be detachably plugged in, and the main card slot and the main card holder are electrically connected through physical contacts or wirelessly; an earphone compartment for placing a Bluetooth headset is arranged on the upper surface of the main card holder; a rechargeable battery is arranged in the base, and the rechargeable battery can charge the Bluetooth headset through the main card holder.

[0007] Furthermore, a flip cover is provided; the base and the flip cover are hinged to each other, and the main card seat is located between the base and the flip cover. The technical effect is that the flip cover can be used to cover the Bluetooth headset to prevent the Bluetooth headset from falling off from the charging box, and a display screen or a circuit board for control can be provided on the flip cover.

[0008] Furthermore, the flip cover is also provided with a display screen, which is provided on a side of the flip cover away from the base. The technical effect is that the display screen is used to control the switching and playing functions of the Bluetooth headset, and to display the playback parameters such as the track, volume, mode, speed, and the device parameters such as the power and charging status of the Bluetooth headset.

[0009] Furthermore, the flip cover is also provided with a display screen; the two opposite ends of the flip cover are respectively hinged with the base and the display screen; when folded, the display screen, the flip cover and the base are connected from top to bottom; when unfolded, the display screen, the flip cover and the base are distributed in a Z shape. The technical effect is that the Z-shaped hinged combination design of the base, the flip cover and the display screen ensures that there is a large operating space when taking and placing the Bluetooth headset and the display screen has a better display effect.

[0010] Furthermore, a circuit board is provided in the flip cover, and the circuit board is electrically connected to the rechargeable battery, the display screen, and the Bluetooth headset respectively. The technical effect is that the circuit board is a data control unit of the charging box, which is used to realize data connection and control operation with the Bluetooth headset and the mobile terminal.

[0011] Furthermore, the number of the main card slot is one, and the number of the main card holder is multiple. The technical effect is that: by setting a main card slot on the upper surface of the base, the sizes of the main card slot and the main card holder can be designed to be larger, the layout of the earphone compartment is more reasonable, and there is less interference between adjacent Bluetooth headsets. Although only one Bluetooth headset on the main card holder can be charged within a period of time, the charging efficiency is higher and the stability is better. In addition, when one pair of Bluetooth headsets is charging, the other pair can also be stored together to avoid loss, and when one pair of Bluetooth headsets is playing music, the other pair can be placed in the charging box for charging.

[0012] Furthermore, the number of the main card slots is multiple, the number of the main card holders is also multiple, and the multiple main card holders correspond one to one with the multiple main card slots. The technical effect is that: at this time, multiple main card holders can be charged at the same time, and you can arbitrarily choose one of the Bluetooth headsets to play and listen to music. When the Bluetooth headset runs out of power, you can switch to another Bluetooth headset that has been charged at any time to achieve seamless switching of Bluetooth headsets. In addition, multiple main card slots are set on the upper surface of the base, so that the Bluetooth headsets on multiple main card holders can be charged at the same time to meet the normal battery life requirements of multiple people and multiple headsets. For example, one main card holder is used to place casual version headsets, one main card holder is used to place business version headsets, and one main card holder is used to place sports version headsets.

[0013] Furthermore, a secondary card holder is also provided on the main card holder; the number of the main card slot is one, the number of the main card holder is also one, at least two secondary card slots are provided on the upper surface of the main card holder, and the secondary card slots are detachably plugged into the secondary card holder; the earphone compartment is provided on the upper surface of the secondary card holder. Its technical effect is that this design places multiple pairs of Bluetooth headphones on their respective secondary card holders, and then concentrates them on one main card holder to connect with the base. Using one main card slot enables multiple secondary card holders to be used in parallel, which is convenient for each to play music independently, and is also convenient for forming a unified physical connection with the base for charging.

[0014] A method for switching a Bluetooth headset based on a modular Bluetooth headset charging box comprises the following steps:

[0015] S1, the mobile terminal sends a first instruction to the headset to be switched, and the headset to be switched returns a device identification code to the mobile terminal according to the first instruction.

[0016] S2, the mobile terminal sends a device identification code and a second instruction to the charging box, and the charging box cancels the active pairing with the current headset according to the second instruction, and realizes active pairing with the headset to be switched.

[0017] A method for switching a Bluetooth headset based on a modular Bluetooth headset charging box comprises the following steps:

[0018] Step 1: The charging box sends a release command to the mobile terminal, and the mobile terminal disconnects the current headset according to the release command;

[0019] Step 2: The charging box sends a pairing instruction to the mobile terminal, and the mobile terminal connects and pairs with the earphone to be switched according to the instruction.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] A modular Bluetooth headset charging box and a Bluetooth headset switching method utilize a detachable main card holder and a main card slot to achieve playback signal switching and control signal switching between a charging box or a mobile terminal and different Bluetooth headsets, which greatly expands the practical functions of the charging box.

[0054] Sixth embodiment:

[0055] Figure 6 This is a flow chart of a Bluetooth headset switching method according to a sixth embodiment of the present invention. Figure 6 As shown, a Bluetooth headset switching method based on a modular Bluetooth headset charging box includes the following steps:

[0056] S1, the mobile terminal sends a first instruction to the headset to be switched, and the headset to be switched returns a device identification code to the mobile terminal according to the first instruction.

[0057] S2, the mobile terminal sends a device identification code and a second instruction to the charging box, and the charging box cancels the active pairing with the current headset according to the second instruction, and realizes active pairing with the headset to be switched.

[0058] In this embodiment, the user starts a dedicated APP on the mobile terminal to manage the connected devices. Through the APP interface, the user can see the connection status of the current earphone, the earphone to be switched, and the charging box.

[0059] When the user starts the "device pairing switching" function, the APP will send a first command such as an AT command to the headset to be switched to obtain the device identification information of the headset to be switched, such as the serial number and or Bluetooth MAC address.

[0060] Next, the mobile terminal transmits the identification information of the earphone to be switched to the charging box, and issues a second instruction to instruct the charging box to prepare to complete the switch.

[0061] Then, the charging box disconnects from the actively paired current earphone, and directly pairs with the earphone to be switched to become the master device, maintaining the control role for the earphone to be switched, i.e., the new current earphone.

[0062] The Bluetooth headset switching solution of this embodiment enables the headset to be switched to smoothly take over the audio playback and receive the command signal, ensuring uninterrupted control through the charging box.

[0063] Seventh embodiment:

[0064] Figure 7 FIG. 1 is a flow chart of a Bluetooth headset switching method according to a seventh embodiment of the present invention. Figure 7 As shown, a Bluetooth headset switching method based on a modular Bluetooth headset charging box includes the following steps:

[0065] Step 1: The charging box sends a release command to the mobile terminal, and the mobile terminal disconnects the current headset according to the release command.

[0066] Step 2: The charging box sends a pairing instruction to the mobile terminal, and the mobile terminal connects and pairs with the earphone to be switched according to the instruction.

[0067] In the Bluetooth headset switching method of this embodiment, before the control switching, the current headset and the charging box are independently paired and connected with the mobile terminal. At this time, the charging box is similar to the role of a watch-like accessory, and interacts with the mobile terminal by sending instructions, allowing it to be controlled without affecting the current headset audio stream. Among them, the instruction transmission path includes: the charging box transmits the control instruction (such as volume adjustment or playback control) to the mobile terminal; the volume instruction includes: the mobile terminal adjusts the volume according to the instruction of the charging box, and transmits the volume change directly to the current headset; the playback instruction includes: instructions involving playback functions (such as play / pause, song switching, low-latency mode switching, voice assistant startup) are processed at the mobile terminal level and will not affect the connection stability of the current headset.

[0068] This method is led by the charging box. After the device is switched, the current earphone is disconnected from the mobile terminal, while the earphone to be switched is paired with the mobile terminal. After pairing with the earphone to be switched, the charging box continues to act as a command relay controller to ensure continuous and stable playback control of the current earphone (the paired earphone to be switched).

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
