Technical Field

The application relates to the technical field of sound boxes, in particular to a detachable combined intelligent sound box.

Background

The loudspeaker box is mainly divided into a wired loudspeaker box and a wireless loudspeaker box according to the connection type, wherein the wireless loudspeaker box is rapidly developed along with the popularization of the intelligent mobile equipment. And intelligent audio amplifier is also more and more popularized in recent years, and it not only can carry out wireless connection with outside smart machine, can also have functions such as voice interaction. The intelligent sound box needs to be networked and is in an online state all the time, so that the power consumption is high; in addition, the intelligent sound box is mainly used at home, and therefore needs to be designed into a structure powered by a power line, so that the intelligent sound box is inconvenient to move, needs to be powered off and restarted every time of moving, and is very complicated to use.

The current chinese patent application publication No. CN 107690104A discloses a split intelligent sound box, which comprises a main box body provided with a tuning device and a secondary box body detachably connected with the main box body; the main box body is also provided with a first communication device which is connected with the tuning device and used for communicating with external intelligent equipment and/or the secondary box body, and the secondary box body is internally provided with a microcontroller, a loudspeaker connected with the microcontroller and a second communication device which is connected with the microcontroller and used for communicating with the first communication device and/or the external intelligent equipment; when the main box body is in contact connection with the secondary box body, the main box body and the secondary box body are in wired connection and/or wireless connection; or when the main box body is connected with the secondary box body in a split manner, the main box body is wirelessly connected with the secondary box body.

In the above related technical scheme, the design of split formula is adopted, so that the secondary box body with the loudspeaker can be separated from the main box body, thus the secondary box body can be placed to any position without moving the main box body, and the movement is very convenient. In addition, the secondary box body can be designed to be independently in wireless connection with the external intelligent equipment and used as a sound box of the external intelligent equipment. Correspondingly, however, since the sub-box body and the main box body are also in wireless connection, the sub-box body can be connected with the main box body and the external intelligent device at the same time.

Although the conventional wireless apparatus can wirelessly connect two or more devices at the same time, when a plurality of devices are wirelessly connected at the same time, the wireless apparatus is designed to mainly connect one of the devices in order to avoid interference. Software cannot identify the idea of the user, and cannot clearly know which device music the user wants to play, so that the situation that the secondary box is wirelessly connected with the main box and cannot play when the external intelligent device needs to be used for playing can occur; or when the music of the main box body needs to be played, the secondary box body is wirelessly connected with the external intelligent equipment and cannot be played. To solve this problem, one of the wireless connections needs to be disconnected to avoid interference, which, although it can solve the problem, leads to a very cumbersome use.

Referring to fig. 9 and 11, in the present embodiment, the two charging probes 120 are both disposed at the bottom of the insertion hole 130, and an electrical contact is disposed at the bottom of the sub-box 200 to cooperate with the two charging probes 120, wherein the charging probes 120 are retractable charging probes 120.

The working principle is as follows:

when the secondary box body 200 needs to be installed, the secondary box body 200 is inserted into the jack 130, the buckle 542 and the avoidance groove 150 are aligned and then continuously pushed to the secondary box body 200, the elastic deformation neck 541 is bent and deformed through the guiding of the avoidance groove 150, then the buckle 542 enters the avoidance groove 150, the push to the secondary box body 200 is continuously carried out, the pressing piece 230 can be abutted by the reset button 220, the sliding block 510 is kept still through the pulling force of the reset spring 520, the pressing piece 230 can press the reset button 220, the buckle 542 is just clamped into the clamping groove 160 after the reset button 220 is pressed, and at the moment, the end 541 of the elastic deformation neck can also be abutted to the end of the avoidance groove 150. At this time, when the sub-case 200 is pushed again, the pressing member 230, the elastic deformation neck 541 and the buckle 542 are acted to drive the sliding block 510 to slide synchronously, and at this time, the limiting protrusion 543 enters the limiting groove 170 from the movable groove 180 to lock the elastic deformation neck 541 so that it cannot deform.

In the sliding process of the sliding block 510, the guiding portion 531 on the pull rod 530 slides along the heart-shaped guiding groove 511, when the sub-tank 200 is pushed to the bottom end of the insertion hole 130 and loosened, the guiding portion 531 falls back to the heart-shaped concave portion of the heart-shaped sliding groove 140 from the top end of the heart-shaped guiding groove 511, so as to pull the sliding block 510, and at this time, the charging probe 120 is in contact with the electrical contact point at the bottom of the sub-tank 200 to charge the power supply, and at this time, the sub-tank 200 can be installed.

When the secondary box body 200 needs to be disassembled, the secondary box body 200 is pressed to drive the sliding block 510 to move, at the moment, the guide part 531 can slide to the other top end of the heart-shaped guide groove 511, after the secondary box body 200 is loosened, the sliding block 510 is pulled under the action of the return spring 520, at the moment, the guide part 531 falls back into the guide groove on the side surface of the heart-shaped guide groove 511, the sliding block 510 is not pulled at the moment, so the sliding block 510 can reset under the action of the return spring 520, the secondary box body 200 also extends out of the jack 130, and at the moment, the secondary box body 200 is pulled out.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
