DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-6 A mobile power supply with a detachable speaker comprises a power supply body 1 and speakers 2. The speakers 2 are two, each with a built-in battery, and are symmetrically arranged on both sides of the power supply body 1 along the central axis of the power supply body 1. A connecting part 3 is fixedly arranged on the power supply body 1.

[0029] The connection part 3 is fixedly provided with a charging part 4 corresponding to the charging port of the mobile phone and a charging port 5 for charging the mobile power supply, and the power supply body 1 is connected to the speaker 2 through a connection structure 6;

[0030] A protrusion 7 is fixedly provided on the power source body 1 , a positioning ring 8 corresponding to the protrusion 7 is fixedly provided on the speaker 2 , and a positioning groove matched with the positioning ring 8 is formed on the protrusion 7 .

[0031] In the utility model, by providing a positioning ring 8 in cooperation with the positioning groove, the speaker 2 is conveniently connected to the power supply body 1, and dust can be prevented from entering the connection between the speaker 2 and the power supply body 1. It can play a role in preventing dust and preventing dust from entering the speaker 2 and the power supply body 1. In the present embodiment, the speaker 2 is a Bluetooth speaker.

[0032] Furthermore, in the present embodiment, the connection structure 6 includes two magnets 61 , and the two magnets 61 are fixedly disposed on the protrusion 7 and the speaker 2 , respectively. The two magnets 61 attract each other to form a magnetic attraction structure, thereby fixing the speaker 2 on the protrusion 7 .

[0033] Furthermore, in the present embodiment, a transmitting coil 71 and a receiving coil 72 are provided in the raised portion 7 and the speaker 2 respectively, so as to wirelessly charge the speaker 2, so as to avoid the inconvenience of plug-in charging affecting the user experience, and to avoid the problem of poor contact after long-term use of plug-in charging.

[0034] It should be noted that, in the present embodiment, two connecting blocks 21 are fixedly provided on the magnetic speaker 2, and slots matching the two connecting blocks 21 are provided on the raised portion 7. By plugging the connecting blocks 21 into the slots, the tightness between the speaker 2 and the power supply body 1 is increased, and when the speaker 2 is placed, the connecting blocks 21 can be used to prop up the speaker 2 to reduce resonance with a supporting object (such as a table).

[0035] In addition, in this embodiment, an anti-idiot groove 22 is provided on the connecting block 21, and an anti-idiot protrusion corresponding to the anti-idiot groove 22 is fixedly provided on the slot corresponding to the connecting block 21, so that the sound emission directions of the two speakers 2 are consistent to avoid mutual interference.

[0036] In detail, the charging part 4 is slidably connected to the connecting part 3. When not charging, part of the charging part 4 can be retracted into the connecting part 3 to protect it and reduce space occupancy. A positioning structure 31 that cooperates with the charging part 4 is provided in the connecting part 3. The positioning structure 31 is provided to limit the position of the charging part 4 to prevent it from being separated and misplaced from the connecting part 3.

[0037] In more detail, in some embodiments, the positioning structure 31 includes a slide 311 fixedly connected to the charging part 4, a guide frame matched with the slide 311 is fixedly provided in the connecting part 3, a limiting hole 312 is provided at the lower end of the slide 311, an elastic strip 313 matched with the limiting hole 312 is fixedly provided in the guide frame, and a wedge block 314 corresponding to the limiting hole 312 is fixedly provided on the elastic strip 313. The position of the slide 311 is limited by setting the wedge block 314 and the elastic strip 313 to cooperate with the limiting hole 312. When the charging part 4 is pulled to charge a mobile phone, the slide 311 will be driven to move, and the limiting hole 312 will be engaged with the wedge block 314. When the charging part 4 moves in the opposite direction, it will abut against one side of the wedge block 314, thereby being unable to move, thereby preventing the charging part 4 from retracting into the connecting part 3 during charging.

[0038] In some embodiments, a through slot is provided on the connecting portion 3, and connecting strips are fixedly arranged on the two elastic strips 313. The two connecting strips pass through the through slot and are fixedly connected with a toggle block 315. An elastic member 316 corresponding to the slide seat 311 is fixedly arranged in the guide frame. By moving the toggle block 315, the elastic strip 313 is elastically deformed, so that the wedge block 314 is separated from the limiting hole 312, so as to facilitate the movement of the charging part 4.

[0039] Working method: The two magnets 61 attract each other to form a magnetic attraction structure, and the speaker 2 is fixed on the raised part 7. By setting a positioning ring 8 to cooperate with the positioning groove, it is convenient to connect the speaker 2 with the power supply body 1, and can prevent dust from entering the connection between the speaker 2 and the power supply body 1, and can play a role in preventing dust and preventing dust from entering the speaker 2 and the power supply body 1. The tightness between the speaker 2 and the power supply body 1 is increased by plugging the connecting block 21 with the slot. By opening an anti-fool groove 22 on the connecting block 21, the sounding parts of the two speakers 2 are in the same direction to avoid mutual interference. The transmitting coil 71 cooperates with the receiving coil 72 to wirelessly charge the speaker 2;

[0040] When not charging, the charging part 4 can be partially retracted into the connecting part 3 to protect it. The positioning structure 31 is set to limit the position of the charging part 4 to prevent it from being separated and misplaced from the connecting part 3. When charging, the sliding seat 311 is driven to move by moving the charging part 4, thereby pressing a wedge block 314 to move downward, so that the elastic strip 313 connected to the wedge block 314 is elastically deformed. When the charging part 4 is completely taken out, the wedge block 314 is inserted into the limiting hole 312 to fix the charging part 4 to prevent it from being retracted into the connecting part 3 when connected to the mobile phone.

[0041] When the charging part 4 is retracted into the connecting part 3, the moving toggle block 315 drives the connecting strip to move, causing the elastic strip 313 to undergo elastic deformation, thereby driving the wedge block 314 to separate from the limiting hole 312, so as to facilitate the movement of the charging part 4. When part of the charging part 4 is retracted into the connecting part 3, the slide 311 abuts against the elastic member 316, causing the elastic member 316 to undergo elastic deformation, and the limiting hole 312 of the slide 311 is engaged with another wedge block 314 to fix the position of the charging part 4. When the wedge block 314 is separated from the limiting hole 312, the elastic member 316 is reset to push the slide 311 to move, thereby causing the wedge block 314 to be misaligned with the limiting hole 312, thereby avoiding restricting the slide 311 again.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
