The operation of the bluetooth headset 10 will be described below (please refer to fig. 1 and fig. 2 together):
when the earphone body 30 is taken out of the earphone accommodating groove 50, the earphone charging pin 60 is completely accommodated in the movable accommodating cavity 330 (as shown in fig. 7);
when the earphone body 30 needs to be reset and charged, the earphone body 30 is placed in the earphone accommodating groove 50 and the earphone body 30 is pressed with light force, so that the earphone charging pin 60 protrudes from the movable accommodating cavity 330; at this time, the earphone charging pin 60 is electrically inserted into the earphone charging hole, and the charging box body 40 charges the earphone body 30;
when the earphone body 30 needs to be taken out of the earphone accommodating groove 50 for use, the user needs to press the earphone body 30 slightly hard and then release the hand; after the hands are released, the earphone body 30 partially pops out of the earphone accommodating groove 50 under the action of the popping mechanism 100; at this time, the user can easily take out the earphone body 30 from the earphone accommodating groove 50 by grasping a portion of the earphone body 30 which is popped out of the earphone accommodating groove 50;
here, it should be particularly noted that if the user does not press the earphone body 30 with a slight light force when placing the earphone body 30 in the earphone receiving groove 50, the earphone body 30 cannot be accommodated in the earphone receiving groove 50 more, which makes the earphone body 30 not be stably accommodated in the earphone receiving groove 50; in this state, the earphone charging pin 60 is completely accommodated in the movable accommodating cavity 330 (as shown in fig. 10), that is, the earphone charging pin 60 cannot be electrically plugged into the earphone charging hole of the earphone body 30, and the earphone body 30 cannot be charged.
Here, it is necessary to explain the operation principle of the eject mechanism 100 (please refer to fig. 1 to 10):
in a state where the earphone body 30 is taken out from the earphone accommodating groove 50, the pop-up mechanism 100 is in an initial state; at this time, the third spring 800 is in an extended state, and the earphone charging pin 60 is completely accommodated in the movable accommodating chamber 330; when the earphone body 30 is taken out from the earphone accommodating groove 50, the earphone charging pin 60 is completely accommodated in the movable accommodating cavity 330, so that the earphone charging pin 60 is protected, and the earphone charging pin 60 is prevented from protruding from the movable accommodating cavity 330 and being easily broken by mistake or electrically misconnected; moreover, at this time, the movable unlocking piece 300 protrudes more from the fixed base 200, so that when the earphone body 30 is placed back in the earphone accommodating groove 50, the movable unlocking piece 300 blocks the earphone body 30, and the earphone body 30 cannot be stably accommodated in the earphone accommodating groove 50; therefore, the user can be reminded, the user is reminded that the earphone body 30 is not charged at the moment, and the user needs to slightly press the earphone body 30;
when the user has used the earphone body 30, the user presses the earphone body 30 with a light force after putting the earphone body 30 back into the earphone accommodating groove 50, thereby indirectly pressing the movable unlocking member 300; the movable unlocking member 300 slides downward in a direction to penetrate into the fixed base 200 when being stressed; in this process, the outer sidewall of the movable unlocking member 300 continuously presses the first inclined upper locking surface 231 of the movable locking piece 230; the movable locking piece 230 is continuously retracted to the direction deep into the avoiding groove 210 to form avoidance for the movable unlocking piece 300, so that the movable unlocking piece 300 smoothly slides downwards; meanwhile, the second spring 220 continuously compresses and accumulates elastic potential energy; in this process, the first inclined force-applying surface 331 of the movable unlocking member 300 continuously abuts against the first inclined force-applying portion 610, so that the inclined connecting rod portion 620 drives the driving connecting rod 700 to move upward, the driving connecting rod 700 drives the earphone charging pin 60 to move upward, and the earphone charging pin 60 passes through the through hole 333 and partially protrudes out of the movable accommodating cavity 330; and in this process, the third spring 800 is continuously compressed and accumulates elastic potential energy;
as shown in fig. 10, when the ring-shaped base 320 of the movable unlocking member 300 passes over the movable locking piece 230, the movable locking piece 230 instantaneously protrudes out of the escape groove 210 under the elastic restoring force of the second spring 220 and forms a barrier to the unlocking ring 500; at this time, the earphone body 30 is released (i.e., the force applied to the movable unlocking member 300 is stopped), the earphone body 30 is stably accommodated in the earphone accommodating groove 50, and at this time, the earphone charging pin 60 is electrically inserted into the earphone charging hole, and the charging box body 40 charges the earphone body 30; although in this state, the third spring 800 has a restoring tendency to make the movable unlocking member 300 protrude from the fixed base 200; at this time, however, the movable locking block 230 extends to the annular groove 310 and blocks the movable unlocking member 300, preventing the movable unlocking member 300 from being reset in a direction protruding from the fixed base 200; thus, the movable unlocking member 300 is stably maintained in the current state;
when the earphone body 30 needs to be taken out of the earphone accommodating groove 50, the user needs to press the earphone body 30 again (i.e. indirectly press the movable unlocking piece 300); it should be noted that the force for pressing the earphone body 30 when the earphone body 30 is taken out is greater than the force for pressing the earphone body 30 when the earphone body 30 is placed; when the earphone body 30 is pressed again, the movable unlocking piece 300 continues to slide downwards; in this process, the third inclined unlocking surface 520 continuously presses the first inclined upper locking surface 231 of the movable locking block 230, so that the movable locking block 230 continuously retracts in the direction of the avoiding groove 210 to form an avoiding for the unlocking ring 500, and the unlocking ring 500 smoothly passes over the movable locking block 230;
in the process, the first inclined force application surface 331 of the movable unlocking member 300 continuously supports against the first inclined force application portion 610, so that the inclined connecting rod portion 620 drives the driving connecting rod 700 to move upward, and the driving connecting rod 700 drives the earphone charging pin 60 to move upward; because the earphone charging pin 60 is of an elastic telescopic structure, in the process that the driving connecting rod 700 drives the earphone charging pin 60 to move upwards continuously, the fixed sleeve column 601 moves upwards continuously, the conductive spring compresses continuously, and the movable needle 603 retracts towards the direction close to the fixed sleeve column 601 under the pressing of the earphone body 30; and in the process, the third spring 800 further compresses and continues to accumulate elastic potential energy;
as shown in fig. 10, after the unlocking ring 500 smoothly passes over the movable locking block 230, the movable locking block 230 instantly protrudes out of the avoiding groove 210 and abuts against the second inclined unlocking surface 510 of the unlocking ring 500 under the elastic restoring force of the second spring 220; at this time, the third inclined unlocking surface 520 is closely attached to the first inclined unlocking surface 321;
as shown in fig. 10, when the unlocking ring 500 smoothly passes over the movable locking block 230, the earphone body 30 can be released; at the moment of releasing the earphone body 30, the third spring 800 extends and resets, so that the movable unlocking piece 300 is jacked up, and the movable unlocking piece 300 drives the unlocking ring 500 to move upwards together; at this time, the movable locking block 230 abuts against the second inclined unlocking surface 510, so that the movable locking block 230 is continuously abutted in the process that the unlocking ring 500 moves upwards, the movable locking block 230 is continuously retracted towards the direction deep into the avoiding groove 210 to form avoidance for the unlocking ring 500 and the movable unlocking piece 300, and the unlocking ring 500 and the movable unlocking piece 300 are instantly bounced, so that the earphone body 30 is instantly bounced; after the earphone body 30 is bounced from the earphone accommodating groove 50, the user can easily take the earphone body 30 out of the earphone accommodating groove 50;
here, it should be particularly noted that the elastic force of the first spring 400 is very small, and the elastic force of the third spring 800 is much larger than that of the first spring 400; the third spring 800 lifts the unlocking ring 500 and the movable unlocking member 300 at such a high speed that the elastic restoring force of the first spring 400 to the unlocking ring 500 does not have time to separate the third inclined unlocking surface 520 of the unlocking ring 500 from the first inclined unlocking surface 321 of the annular groove 310; this ensures that the unlocking ring 500 and the movable unlocking member 300 are instantaneously bounced over the movable locking piece 230 in an integrated manner; after the unlocking ring 500 bounces up with the movable unlocking member 300, the unlocking ring 500 slightly moves up under the elastic force of the first spring 400, so that the third inclined unlocking surface 520 of the unlocking ring 500 is separated from the first inclined unlocking surface 321 of the annular groove 310 to wait for the next charging press;
it should be noted that, during the process of the movable unlocking member 300 bouncing up, the second inclined force-applying surface 332 continuously supports against the second inclined force-applying portion 630, so that the Z-shaped driving member 600 moves toward the first inclined force-applying surface 331, and the inclined link 620 drives the driving link 700 to move downward; the earphone charging pin 60 is driven to move downwards in the process of driving the connecting rod 700 to move downwards, so that the earphone charging pin 60 retracts into the movable accommodating cavity 330;
when the bluetooth headset 10 of the present invention charges the headset body 30, the headset body 30 is pressed with a slight light force only when the headset body 30 is placed in the headset receiving groove 50; this pressing retracts the movable unlocking member 300 toward the fixed base 200, so that the earphone body 30 is stably accommodated in the earphone accommodating groove 50; on the other hand, the earphone charging pin 60 protrudes out of the movable accommodating cavity 330, so that the earphone charging pin 60 is electrically inserted into the earphone charging hole of the earphone body 30, and the charging box body 40 charges the earphone body 30;
when the earphone body 30 needs to be taken out from the earphone accommodating groove 50, the earphone body 30 only needs to be pressed again (the pressing force is larger than that when the earphone body 30 is charged), and then the earphone body 30 is loosened; this pressing causes the unlocking ring 500 and the movable unlocking member 300 to tightly abut against each other and to instantly bounce over the movable locking block 230 together in an integrated manner; on the other hand, the earphone charging pin 60 is protected by the elastic driving link 700 of the movable unlocking member 300 to retract the earphone charging pin 60 into the movable accommodating cavity 330.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
