DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] like Figure 1 FIG. 1 is a structural diagram of a Bluetooth headset with a mobile phone anti-theft system according to an embodiment of the present invention, comprising a headset body 1, a processor 2 disposed in the headset body 1, and an anti-theft mechanism wirelessly connected to a mobile phone. The anti-theft mechanism includes a distance sensing module that detects the distance by sensing the signal strength between the mobile phone and the headset body 1. The anti-theft mechanism also includes:

[0032] A display mechanism 3 is provided in the headset body 1 and is electrically connected to the processor 2, and is used to display the relative position of the headset body 1 and the mobile phone;

[0033] a protective mechanism, disposed on the display mechanism 3 and detachably connected to the earphone body 1 via a limiting mechanism, for isolating the display mechanism 3 from external communication with the earphone body 1; and

[0034] The wire automatic retraction mechanism is arranged on the side of the display mechanism 3 away from the protection mechanism;

[0035] The automatic wire retraction mechanism includes a spiral rod 5 rotatably connected to the earphone body 1, and a power cord 4 connected to the display mechanism 3 is wound around the spiral rod 5. The end of the power cord 4 away from the display mechanism 3 is electrically connected to the processor 2 through a connecting mechanism;

[0036] The distance sensing module is provided with an alarm, and when the distance between the mobile phone and the headset body 1 reaches a predetermined value, the alarm sounds an alarm.

[0037] In an embodiment of the present invention, when the distance between the mobile phone and the headset body 1 reaches a predetermined value, the alarm sounds an alarm. At this time, the protective mechanism can be disassembled from the headset body 1, and the display mechanism 3 can be taken out. The display mechanism 3 drives the power cord 4 to disengage from the spiral rod 5, and the spiral rod 5 rotates, so that the automatic wire retraction mechanism generates torque. At this time, the mobile phone can be found by observing the relative position between the mobile phone and the display mechanism 3. After use, the torque force of the automatic wire retraction mechanism drives the spiral rod 5 to rotate in the opposite direction, drives the power cord 4 and thus drives the display mechanism 3 to be stored in the headset body 1, and the display mechanism 3 drives the protective mechanism to be fixed to the headset body 1 again.

[0038] In addition, it should be noted that in actual application, in order to better cooperate with the display mechanism 3, the automatic wire retraction mechanism provided here is for better use by the display mechanism 3.

[0039] In one case of this embodiment, the earphone body 1 is provided with a second accommodating cavity 27 for accommodating the display mechanism 3, and the opening side of the second accommodating cavity 27 is in contact with the protective mechanism. This arrangement allows the display mechanism 3 to be easily removed, and the spiral rod 5 is arranged in the second accommodating cavity 27.

[0040] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, the connecting mechanism includes a connecting base 12 electrically connected to the processor 2, the connecting base 12 is provided with a through groove for the spiral rod 5 to be nested, a rolling contact assembly is provided in the connecting base 12 and connected to the spiral rod 5, the rolling contact assembly is electrically connected to the processor 2 through a connecting wire 10, the end of the power cord 4 away from the display mechanism 3 is fixedly connected to the spiral rod 5, and the end of the spiral rod 5 fixed to the power cord 4 is a conductive part 7.

[0041] In an embodiment of the present invention, when the protective mechanism is released, the protective mechanism drives the display mechanism 3 and thus drives the power cord 4 away from the earphone body 1. At this time, the power cord 4 drives the spiral rod 5 to rotate, and while the spiral rod 5 rotates, it is connected to the connecting wire 10 and the processor 2 through the rolling contact assembly.

[0042] In one case of this embodiment, the earphone body 1 is provided with a third accommodating cavity 28 for accommodating the processor 2 and the connecting base 12. By providing the third accommodating cavity 28, it is convenient to isolate the processor 2 and the connecting base 12 to prevent the processor 2 and the connecting base 12 from contacting the outside world, thereby preventing leakage. In addition, it should be noted that the power cord 4 is arranged in the accommodating groove 11 provided with the spiral rod 5 and is fixed to the conductive part 7. This arrangement prevents the power cord 4 from being easily disconnected from the conductive part 7, thereby strengthening the fastening environment.

[0043] like Figure 1 As shown, as another preferred embodiment of the present invention, the rolling contact assembly includes an annular conductor 8 arranged in the connecting base 12 and located on the outside of the conductive part 7, and a ball 9 is arranged between the annular conductor 8 and the conductive part 7, and the conductive part 7 and the annular conductor 8 are both provided with a limiting rolling groove that cooperates with the ball 9.

[0044] In an embodiment of the present invention, when the protective mechanism drives the display mechanism 3 and thus drives the power cord 4 away from the earphone body 1, the power cord 4 drives the spiral rod 5 to rotate, and the rotation of the spiral rod 5 generates friction between it and the ball 9. The ball 9 rolls between the conductive part 7 and the annular conductor 8, and conduction is established between the power cord 4, the conductive part 7, the ball 9, and the annular conductor 8. The ball 9 can also conduct electricity between the conductive part 7 and the annular conductor 8 while rotating with the conductive part 7, which is convenient to use and can reduce friction resistance and increase service life.

[0045] like Figure 1 As shown, as another preferred embodiment of the present invention, the protective mechanism includes a protective plate 14 that is in contact with the earphone body 1, and the protective plate 14 is fixed to the display mechanism 3 through a connecting rod 13, and the display mechanism 3 is abutted against a limit block fixedly connected to the earphone body 1.

[0046] In an embodiment of the present invention, the torque force generated by the spiral rod 5 pulls the power cord 4, thereby pulling the display mechanism 3 into contact with the limit block, and the protection is further limited by the limiting mechanism. Only when the alarm sounds an alarm can the protection mechanism be separated from the earphone body 1.

[0047] like Figure 1 As shown, as another preferred embodiment of the present invention, the automatic wire retraction mechanism also includes a storage box 6 arranged in the earphone body 1, and an elastic retractable part is provided in the storage box 6. The elastic retractable part can be preferably an elastic rope or an elastic spring. It only needs to be elastic and can be pulled and wound by the spiral rod 5, and there is no restriction on this.

[0048] In the embodiment of the present invention, the earphone body 1 is provided with a first accommodating cavity 26 for accommodating the storage box 6 , so as to facilitate subsequent maintenance and replacement.

[0049] like Figure 1 、 Figure 3 As shown, as another preferred embodiment of the present invention, the limiting mechanism includes a connecting block 15 fixedly connected to the protective mechanism, and the connecting block 15 is clamped with a clamping block 16 slidably connected to the earphone body 1. The part where the clamping block 16 is nested in the earphone body 1 is an arc surface along the displacement direction of the protective mechanism, and the clamping block 16 is connected to an elastic limiting component.

[0050] In the embodiment of the present invention, the clamping block 16 is limited by the elastic limiting assembly, so that the clamping block 16 is nested in the connecting block 15 under the action of elastic force, thereby fixing the protective mechanism through the connecting block 15.

[0051] like Figure 3 As shown, as another preferred embodiment of the present invention, the elastic limiting assembly includes a limiting block 19 that is fixed through the snap-fit ​​block 16 and is slidably connected to the earphone body 1, and the earphone body 1 is provided with a slide groove 17 that cooperates with the limiting block 19, and the slide groove 17 is elastically connected to the snap-fit ​​block 16 through an elastic member 18.

[0052] In the embodiment of the present invention, it is only necessary to use force to drive the protective mechanism to separate from the earphone body 1. The earphone body 1 drives the connecting block 15 to squeeze the arc surface of the clamping block 16 so that the clamping block 16 retracts into the earphone body 1 and thus separates from the connecting block 15. At this time, the clamping block 16 drives the limit block 19 to slide along the slide groove 17, and the clamping block 16 squeezes the elastic member 18.

[0053] like Figure 3 、 Figure 4 As shown, in order to further improve the fixation degree of the connecting block 15, as another preferred embodiment of the present invention, a slot 20 is provided in the clamping block 16, and the side of the slot 20 away from the head of the clamping block 16 is a slanted wall 21, and the lower end of the slanted wall 21 is away from the head of the clamping block 16. An extrusion rod 22 abutting against the slanted wall 21 is provided in the slot 20, and the extrusion rod 22 is connected to a convenient pressing component, which makes it easy for the extrusion rod 22 to squeeze the clamping block 16.

[0054] In the embodiment of the present invention, in actual application, it is often in an emergency situation and it is inconvenient for a small number of people to pull the protective mechanism. At this time, the squeezing rod 22 can be squeezed, and the squeezing rod 22 squeezes the inclined wall 21. Due to the characteristics of its own shape, the inclined wall 21 drives the clamping block 16 to separate from the connecting block 15, thereby making it easy for the protective mechanism to separate from the earphone body 1.

[0055] like Figure 3As shown, as another preferred embodiment of the present invention, the convenient pressing assembly includes an extrusion plate 23 fixedly connected to the extrusion rod 22, and the earphone body 1 is provided with a limiting groove 24 slidingly connected to the extrusion plate 23, and the limiting groove 24 is connected to the outside of the earphone body 1 through an extrusion through-hole 25 whose outer diameter is smaller than the limiting groove 24. The extrusion plate 23 is squeezed through the extrusion through-hole 25, and the extrusion plate 23 drives the extrusion rod 22 to squeeze the clamping block 16 along the inclined wall 21, and the setting of the extrusion through-hole 25 just limits the extrusion plate 23, so that under normal circumstances, it is not easy to squeeze the extrusion plate 23 by mistake.

[0056] like Figure 1 、 Figure 5 As shown, due to the size limitation of the earphone body 1, the size of the display mechanism 3 is also limited. If a map is used, it will be difficult for the user to observe due to the size limitation of the display mechanism 3. Therefore, as another preferred embodiment of the present invention, the display mechanism 3 is provided with a dial 29, and the dial 29 is rotatably provided with a pointer 30, one end of the pointer 30 is a movable end and points in the direction of the mobile phone.

[0057] In the embodiment of the present invention, by arranging the pointer 30 to cooperate with the distance sensing module, the position of the mobile phone can be quickly locked, which is convenient for operation.

[0058] The above embodiment of the present invention provides a Bluetooth headset with a mobile phone anti-theft system. By setting a display mechanism 3, a protective mechanism and an automatic wire retraction mechanism, the display mechanism 3 has two forms. One can be set inside the headset body 1, and the other is outside the headset body 1, which is convenient for the user to hold and watch. In the two forms, the power cord 4 connected to the display mechanism 3 can be well stored and tidied, and there will be no problem of poor telecommunication connection, thereby achieving the purpose of good protection of the display mechanism 3, and it is easy to use and quick to operate.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
