In a specific embodiment of the bluetooth headset case provided by the present invention, the bluetooth headset case includes a base 5, an upper case 2, and a control circuit.

The upper case 2 is used to open or cover the notch of the earphone mounting groove 51 on the base 5. The upper shell 2 is rotatably connected to the base 5 through a rotating shaft 6. In this embodiment, the number of the upper case 2 is one, but of course, in other embodiments, the number of the upper case 2 may be two or other numbers so as to completely cover the notch of the earphone mounting groove 51 by the fitting of the upper case 2.

An upper shell magnetic part 3 is fixed on the upper shell 2, and a control circuit comprises a switch component 7 and a solenoid of the upper shell magnetic part 3 which are connected in series. The switch component 7 is arranged on the base 5, and the closing magnetic part 4 is fixed on the base 5.

When the upper case 2 rotates to a preset closing position, the upper case 2 covers the notch of the earphone mounting groove 51, and the closing magnetic part 4 is attached to the upper case magnetic part 3. At this time, the solenoid can generate magnetism repulsive to the closing magnetic member 4 by controlling the state of the switch assembly 7 to push the upper case 2 to move toward the preset opening position, opening the notch of the earphone mounting groove 51.

Specifically, the preset opening position and the preset closing position are two positions corresponding to the upper housing 2 with the base 5 as a reference, and the two positions may specifically limit a rotatable range of the upper housing 2.

In this embodiment, through the control to switch module 7, can change the on-off condition of control circuit and the electric current in the solenoid, make upper shell magnetic part 3 rotate in order to open through with closing magnetic part 4 repulsion in order to drive upper shell 2, because the size of magnetism repulsion can be set for the power that upper shell 2 turned away required size in the manufacture process, the size of this power is confirmed in the use, can reduce the direct operation of exerting the indefinite thrust of size on upper shell 2 of user, can reduce the impact that causes to axis of rotation 6, the life of extension earphone box.

Further, an opening magnetic member 9 is fixed on the base 5. When epitheca 2 rotated to predetermineeing the open position, epitheca 2 opened the notch, opened magnetic part 9 and the laminating of epitheca magnetic part 3 mutually, can make the solenoid produce and open the magnetism that magnetic part 9 repetitious through control switch subassembly 7 state to promote epitheca 2 and predetermine closed position motion.

The opening magnetic member 9 and the closing magnetic member 4 may be always magnetic or may generate magnetism only in a specific time period. The opening magnetic part 9 and the closing magnetic part 4 can be permanent magnets, specifically strong permanent magnets, and cost saving is facilitated. Of course, in other embodiments, the opening magnetic element 9 and/or the closing magnetic element 4 may also be electromagnets.

Wherein, optionally, as shown in fig. 2, an arc-shaped guide channel for guiding the upper shell 2 is provided in the base 5, the upper shell 2 is slidably connected in the guide channel, and the opening magnetic member 9 and the closing magnetic member 4 are provided at both ends of the guide channel. The upper case magnetic member 3 is embedded in the upper case 2. Preferably, the opening magnetic part 9 and the closing magnetic part are arranged at two ends of the upper shell magnetic part 3 in the moving direction, the upper shell 2 cannot continue to be opened and moved through the abutting limit of the upper shell magnetic part 3 and the opening magnetic part 9 after moving to the preset opening position, and the upper shell 2 cannot continue to be closed and moved through the abutting limit of the upper shell magnetic part 3 and the closing magnetic part after moving to the preset closing position.

When the upper shell 2 is at the preset closing position, the rotating shaft 6 is in contact conduction with the closing pin 8 and is disconnected from the opening pin 1. When the upper shell 2 is at the preset opening position, the rotating shaft 6 is in contact conduction with the opening pin needle 1 and is disconnected with the closing pin needle 8.

That is, the pin branch and the rotating shaft form a pin branch switch component. The on-off of the control circuit is controlled by the pin branch switching element and the switching component 7 together, and only when the pin branch switching element and the switching component 7 are closed simultaneously, the control circuit can form a passage, and the solenoid can be electrified; the pin branch switching element and the switching element 7 are both opened, the control circuit is opened, and the solenoid is not energized.

In addition to the spindle 6, the pin branch, the switch component 7, and the solenoid, the control circuit may further include other components such as a power supply and a resistor, and may be disposed in an upper shell branch 11 fixed in the upper shell 2 or a base branch 12 fixed in the base 5. In addition, a charging assembly is generally provided in the base 5 to charge the earphone body 10.

Preferably, the rotating shaft 6 is provided with a groove-type closing contact piece 63 buckled on the closing pin 8 and a groove-type opening contact piece 62 buckled on the opening pin 1.

So set up, can guarantee the reliability of pivot 6 and pin needle contact. Meanwhile, due to the arrangement of the opening contact piece 62 and the closing contact piece, on the rotating shaft 6, except that the opening contact piece 62 and the closing contact piece 63 need to be made of conductive materials, whether the rest parts have conductive capacity or not can be set as required, for example, the opening contact piece 62 and the closing contact piece 63 are metal sheets and are connected into a control circuit through wires, and the rest parts on the rotating shaft 6 can be plastic parts, so that the flexibility of material selection is improved. In addition, according to the length setting of the closing contact piece 63 and the opening contact piece 62, the power-on time of the control circuit can be controlled, for example, when the upper shell 2 is at the preset closing position, the switch component 7 is closed, if the closing pin 8 is in point contact with the closing contact piece 63, the control circuit can be switched on for 0.1s along with the rotation of the rotating shaft 6; if close pin 8 and close contact 63 and be the line contact along pivot 6 pivoted direction, then probably pivot 6 is after rotating 2s, close pin 8 and close contact 63 and just separate completely, correspondingly, control circuit switch-on 2s, the solenoid also is 2s with the time correspondence that produces the repulsion between the magnetic part 4 of closing to be favorable to providing sufficient thrust for pivot 6, close contact 63 above can be referred to the length setting mode of opening contact 62, no longer describe.

Further, the close magnetic member 4 and the open magnetic member 9 have opposite poles to each other near the ends.

Specifically, in the present embodiment, as shown in fig. 2 to 4, the N pole of the closing magnetic member 4 is close to the opening magnetic member 9, and the S pole of the opening magnetic member 9 is close to the closing magnetic member 4. When the pin needle 1 is opened to be in contact conduction with the rotating shaft 6 and the switch component 7 is closed, or when the pin needle is closed to be in contact conduction with the rotating shaft 6 and the switch component 7 is closed, the control circuit is conducted to form a loop. Under the conducting state of the control circuit, the upper shell magnetic part 3 is electrified, one end close to the closing magnetic part 4 is an N pole, and one end close to the opening magnetic part 9 is an S pole.

When the solenoid is required to be electrified to push the upper shell 2, no matter the upper shell 2 is in the preset opening position or the preset closing position, the direction of current in the solenoid is consistent, namely one end close to the opening magnetic part 9 and the opening magnetic part 9 repel each other with the same magnetism, and one end close to the closing magnetic part 4 and the closing magnetic part 4 repel each other with the same magnetism, so that the current in the solenoid does not need to be subjected to reversing control, and a control circuit can be simplified. In addition, after the solenoid is de-energized, the rotating shaft 6 can be positioned by opening the magnetic part 9 and closing the magnetic part 4 to suck the demagnetized iron core, and the positioning of the upper shell 2 is not influenced by the direction of the magnetic field generated by the solenoid.

Of course, in other embodiments, the S pole of the closing magnetic member 4 may be close to the opening magnetic member 9, and the N pole of the opening magnetic member 9 may be close to the closing magnetic member 4.

Further, the switch assembly 7 comprises a key with an elastic piece, the switch assembly 7 is closed after the key is pressed to a preset trigger position, and the key can reset under the driving of the elastic piece to enable the switch assembly 7 to be disconnected.

The switch component 7 can be opened and closed by pressing or loosening the key, so that the operation is convenient, the opening and closing time of the switch component 7 can be controlled by a user according to actual needs, and the use flexibility is good.

Of course, in other embodiments, the switch assembly 7 may also be a knob or other switch member.

Further, the upper shell 2 comprises a shell 21 and a counterweight 22, when the upper shell 2 rotates to a preset closing position, the shell 21 covers the notch of the earphone mounting groove 51; the gravity torque generated by the weight 22 relative to the rotation center line of the rotating shaft 6 can balance the gravity torque generated by the housing 21 relative to the rotation center line.

Wherein, when the upper shell 2 is in the preset closed position, the shell 21 is substantially located outside the base 5, and the counterweight 22 is normally located inside the base 5.

Wherein, preferably, the line connecting the centers of gravity of the counterweight 22 and the housing 21 intersects with the rotation center line, so as to determine the relative position when the housing 21 and the counterweight 22 are assembled.

Specifically, as shown in fig. 12, the weight 22 and the housing 21 are located at two sides of the rotating shaft 6, and the weight 22 and the housing 21 are fixed on the rotating shaft 6 by using a locking screw 61. Under the premise of no external force, the distance L1 between the gravity action line of the housing 21 and the rotation center line of the rotating shaft 6 is equal to the distance L2 between the gravity action line of the counterweight 22 and the gravity action line of the counterweight 22, i.e. the gravity G1 of the housing 21 and the rotation center line of the rotating shaft 6, and the counterweight 22 and the housing 21 can keep balance at any position under the premise of no external force, so the repulsive force generated between the upper housing magnetic member 3 and the opening magnetic member 9 and the closing magnetic member 4 is greater than the rotation resistance of the housing 21, and the housing 21 can continuously rotate.

The matching of the balancing weight 22 and the housing 21 can reduce the setting of the current required in the upper shell magnetic part 3, so that the setting of the control circuit is convenient, and the energy is saved.

In this embodiment, a specific operation process of the bluetooth headset box is as follows:

referring to fig. 2 to 7, when the housing 21 is at the preset closing position, the housing 21 completely closes the notch of the earphone mounting groove 51, and the pin 8 is closed to contact the upper spindle 6. At this moment, the button is in the normal position, and switch module 7 cuts off, and the control circuit is broken, and the first solenoid 31 of epitheca magnetic part 3 loses the electricity and loses magnetism, and the iron core attracts with closing magnetic part 4 mutually, keeps the off-state of bluetooth headset box. When the key is pressed down, the switch component 7, the first solenoid 31, the closing pin 8 and the rotating shaft 6 in the control circuit form a passage, the first solenoid 31 is electrified instantly, the magnetic pole attached to the closing magnetic part 4 is an N pole, like poles repel each other, and the shell 21 is stressed to rotate anticlockwise. After the rotating shaft 6 rotates and closes the pin 8 and is separated, the control circuit is switched off, the first solenoid 31 is powered off, the upper shell 2 continues to move to the preset opening position towards the opening magnetic part 9 under the inertia effect, and the iron core in the upper shell magnetic part 3 is attracted with the opening magnetic part 9. Wherein, before the upper shell 2 moves to the preset opening position, the button is released to reset the switch component to be disconnected.

Referring to fig. 8 to 10, when the housing 21 is at the preset open position, the housing 21 completely opens the notch of the earphone mounting groove 51, and opens the pin 1 to contact the spindle 6. At the moment, the button is in the original position, the switch component 7 is disconnected, the control circuit is disconnected, the first solenoid 31 of the upper shell magnetic part 3 loses power and magnetism, the iron core and the opening magnetic part 9 attract each other, and the opening state of the Bluetooth headset box is kept. When the key is pressed down, the switch component 7, the first solenoid 31, the open pin 1 and the rotating shaft in the control circuit form a passage, the first solenoid 31 is electrified instantly, the magnetic pole attached to the open magnetic part 9 is an S pole, the like poles repel each other, and the shell 21 is stressed to rotate clockwise. After the rotating shaft 6 rotates to be separated from the opened pin needle 1, the control circuit is switched off, the first solenoid 31 is powered off, the upper shell 2 continues to move to the preset closing position towards the closed magnetic part 4 under the inertia effect, and the iron core in the upper shell magnetic part 3 is attracted with the closed magnetic part 4. Wherein, before the upper shell 2 moves to the preset closing position, the key is released to reset the key.

When the shell 21 is in a rotating state, the control circuit is in an open circuit state due to the fact that the pin 1 is opened to be separated from the rotating shaft and the pin is closed to be separated from the rotating shaft, and the upper shell magnetic part 3 cannot be electrified and magnetized even if a key is pressed down.

The bluetooth headset box that this embodiment provided can realize the rotatory switching of a key, simultaneously, utilizes electromagnet to lose behind the electricity iron core and permanent magnet attraction can keep opening and the closed condition of epitheca 2.

Obviously, the arrangement of the upper case magnetic member 3 and the switch assembly 7 is not limited to the manner provided in the above-described embodiment.

In another embodiment of the present invention, referring to fig. 13, the upper casing magnetic component 3 is the second solenoid 32, that is, the second solenoid 32 has no iron core, the switch assembly 7 includes an opening switch 71 and a closing switch 72, the opening switch 71 is connected in series with the opening power supply 14 to form an opening branch, the closing switch 72 is connected in series with the closing power supply 15 to form a closing branch, the opening branch and the closing branch are connected in parallel and then connected to the control circuit, when the opening power supply 14 is connected to the control circuit, compared with when the closing power supply 15 is connected to the control circuit, the current direction in the second solenoid 32 is opposite.

When the housing 21 is at the preset opening position, the opening switch 71 is closed, the closing switch 72 is opened, and the upper shell magnetic part 3 and the opening magnetic part 9 attract each other, at this time, the opening switch 71 is opened, the closing switch 72 is closed, the magnetic pole direction of the upper shell magnetic part 3 is changed, and the upper shell 2 is pushed by the magnetic repulsion force between the upper shell magnetic part 3 and the opening magnetic part 9 to move towards the closing magnetic part 4.

When the housing 21 is at the preset closing position, the closing/closing switch 72 opens the opening switch 71, so that the upper magnetic part 3 and the closing magnetic part 4 attract each other, and at this time, the opening/closing switch 72 opens the opening switch 71, the magnetic pole direction of the upper magnetic part 3 changes, and the upper housing 2 is pushed by the magnetic repulsion between the upper magnetic part 3 and the closing magnetic part 4 to move toward the opening magnetic part 9.

The control circuit can control the on-off condition of the switch assembly 7 only, that is, in the closed state of either the open switch 71 or the close switch 72, the control circuit is conducted to form a loop, and the second solenoid 32 is electrified. In addition, since the direction of the current of the second solenoid 32 is adjustable, the magnetic polarities of the close ends of the opening magnetic member 9 and the closing magnetic member 4 may be set to be the same.
