DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] The present invention provides a helmet Bluetooth headset for automatically answering calls, such as Figures 1 to 4 As shown, the helmet 1 includes a helmet 1, both sides of the helmet 1 are provided with sliding openings, a slide plate 2 is slidably installed in the sliding opening, the outer side of the slide plate 2 is symmetrically threaded with a bolt 3, one end of the bolt 3 extends to the inside of the helmet 1, and the inside of the helmet 1 is symmetrically provided with a tuning component 5, which is a tuning component on a helmet Bluetooth headset for automatically answering calls in the prior art. Its working principle is the prior art and is not described in detail here. The tuning component 5 is rotatably connected to the bolt 3, and the inside of the helmet 1 is symmetrically provided with an earphone component 4, which is a helmet Bluetooth headset for automatically answering calls in the prior art. The earphone assembly on the helmet 1 has a working principle that is prior art and will not be elaborated here. A baffle 6 is symmetrically fixedly installed on the outer side of the skateboard 2, an inner rod 7 is rotatably installed between two adjacent baffles 6, the inner rod 7 is connected to the baffle 6 by a movable shaft, an outer sliding sleeve of the inner rod 7 is provided with an outer rod 8, a pair of side panels 9 are fixedly installed on both sides of the helmet 1, a rotating shaft 10 is rotatably installed on the outer side of the side panel 9, one end of the rotating shaft 10 is fixedly connected to the outer rod 8, and a first torsion spring 11 is provided on the outer sleeve of the upper rotating shaft 10, and the two ends of the first torsion spring 11 are respectively fixedly connected to the side panels 9 and the rotating shaft 10.

[0023] When in use, the bolt 3 on one side is rotated forward at the same time to make the tuning component 5 move toward the outside of the helmet 1, so that the distance between the pair of tuning components 5 is adjusted to adapt to the cheek of the user, and the tuning component 5 is adjusted to fit the cheek. During riding, when a call comes in, the tuning component 5 is triggered by blowing air on the cheek to cooperate with the mobile phone Bluetooth to connect the call, and the conversation is carried out through the earphone component 4, so that the call can be answered automatically. When it is necessary to take off the helmet 1, both hands are respectively placed on both sides of the helmet 1, and the two thumbs press the outer rod 8 respectively to make it move with the inner rod 7, the baffle 6 and the skateboard 2, and at the same time, the rotating shaft 10 rotates to make the first torsion spring 11 twist into a torsion shape. The force is generated, and as the slide plate 2 moves, the pair of slide plates 2 move away from each other, thereby moving the bolt 3 and the tuning component 5, so that the tuning component 5 is away from the user's cheek, and then the helmet 1 is pulled upward to separate the helmet 1 from the user's head. In the process of separation, the tuning component 5 is away from the user's cheek, so the tuning component 5 does not generate friction with the user's cheek, avoiding discomfort to the cheek caused by the tuning component 5 when the helmet 1 is removed. After removing the helmet 1, the outer rod 8 can be loosened, and the first torsion spring 11 releases the force to rotate and reset the shaft 10 and the outer rod 8. Conversely, the slide plate 2 can be reset, thereby resetting the tuning component 5.

[0024] like Figures 2 to 4 As shown, vertical grooves are equidistantly arranged around the outside of the lower rotating shaft 10, a ring plate 12 is provided on the external sliding sleeve of the lower rotating shaft 10, a movable block matching the vertical groove is fixedly installed on the inner side of the ring plate 12, a rubber pad 13 is provided on the ring plate 12, a positioning ring 14 is provided on the external sliding sleeve of the lower rotating shaft 10, a positioning block matching the vertical groove is fixedly installed on the inner side of the positioning ring 14, a positioning rod is threadedly connected to the outer side of the positioning ring 14, one end of the positioning rod passes through the positioning block and contacts the inner wall of the vertical groove, a spring 15 is fixedly installed on the bottom of the movable block, and a driving component for driving it to descend is provided on the outer side of the ring plate 12.

[0025] The bottom of the spring 15 is in conflict with the positioning block, and the reaction force of the spring 15 ensures that the movable block, the ring plate 12 and the rubber pad 13 are in conflict with the side plate 9. When the thumb presses the outer rod 8 to rotate the shaft 10, the lower shaft 10 cooperates with the vertical groove to rotate with the movable block and the ring plate 12, and cooperates with the driving component to drive the ring plate 12 and the rubber pad 13 to descend, so that the rubber pad 13 leaves the side plate 9. Therefore, when the outer rod 8 is pressed to make the skateboard 2 move out of the helmet 1, the rubber pad 13 does not contact the side plate 9 during this process, so that the rubber pad 13 will not be worn, and the rubber pad 13 can be protected. When the outer rod 8 is pressed to the point where it cannot move, the driving component cancels the ring plate 12 and the rubber pad 13. The plate 12 is driven, and the movable block, the ring plate 12 and the rubber pad 13 are reset under the action of the spring 15, so that the rubber pad 13 contacts the side plate 9 again. When the helmet is pulled upward, if it is accidentally out of hand, the first torsion spring 11 causes the rotating shaft 10 and the outer rod 8 to rotate and reset. Due to the presence of the rubber pad 13, there is friction between the rubber pad 13 and the side plate 9, so that the rotating shaft 10 can rotate slowly, and the outer rod 8 can rotate and reset slowly, so as to avoid the outer rod 8 from causing the inner rod 7 to collide with the helmet 1 and generate vibration when the outer rod 8 is quickly reset, and transmit the vibration to the tuning assembly 5, so that the tuning assembly 5 can be protected after it is out of hand.

[0026] like Figure 2 As shown, the driving assembly includes a transverse plate 16 fixedly connected to the outer side of the ring plate 12, a bottom plate 17 is fixedly installed on the side of the bottom of the transverse plate 16 away from the ring plate 12, a limiting plate 18 is fixedly connected to the side of the bottom plate 17 away from the helmet 1, a circular shaft 19 is rotatably installed on the bottom of the bottom plate 17, the top of the circular shaft 19 extends to the top of the bottom plate 17 and is fixedly connected to a stop block 20, a second torsion spring is sleeved on the outside of the circular shaft 19, and the two ends of the second torsion spring are respectively fixedly connected to the bottom plate 17 and the circular shaft 19, and an extrusion assembly for driving the stop block 20 to descend is provided on the outside of the helmet 1.

[0027] When the thumb presses the outer rod 8, the rotating shaft 10 rotates with the movable block and the ring plate 12, so that the cross plate 16, the bottom plate 17, the round shaft 19, and the stop block 20 rotate accordingly. After the stop block 20 contacts the extrusion assembly, due to the existence of the limit plate 18, the stop block 20 cannot rotate forward and maintains the original state. As the rotating shaft 10 continues to rotate, the cooperating extrusion assembly drives the stop block 20 to descend with the round shaft 19, the bottom plate 17, the cross plate 16, the ring plate 12 and the rubber pad 13, so that the rubber pad 13 leaves the side plate 9. At the same time, the movable block squeezes the spring 15 to deform it to generate a force. When the stop block 20 separates from the extrusion assembly, at this time, Under the action of the spring 15, the movable block, the ring plate 12 and the rubber pad 13 are reset, so that the rubber pad 13 is in conflict with the side plate 9. When the pressure on the outer rod 8 is released, the rotating shaft 10 rotates and resets. Conversely, the stop block 20 moves accordingly. After the stop block 20 is in conflict with the extrusion assembly, the stop block 20 reverses with the round shaft 19, and at the same time, the second torsion spring torsional deformation generates a force, so that in the process of rotating the rotating shaft 10 rotating and resetting, the rubber pad 13 is always in conflict with the side plate 9, so that the rotation speed of the rotating shaft 10 can be slowed down by friction. When the stop block 20 is separated from the extrusion assembly, the second torsion spring releases its force to rotate and reset the round shaft 19 and the stop block 20.

[0028] like Figure 2 As shown, the extrusion assembly includes a long plate 21 fixedly connected to the outside of the helmet 1, and a driving block 22 is fixedly connected to one end of the long plate 21 close to the stop block 20. The driving block 22 is provided with an arc surface on one side close to the stop block 20, and the stop block 20 can contact the arc surface when moving in the direction close to the helmet 1.

[0029] After the stopper 20 contacts the arc surface, the stopper 20 cannot rotate forward due to the presence of the limiting plate 18, and the stopper 20 moves along the arc surface, causing it to descend.

[0030] like Figure 4 As shown, the rubber pad 13 is bonded to the top of the ring plate 12 , and the rubber pad 13 is in contact with the side plate 9 .

[0031] When the rubber pad 13 needs to be replaced, the positioning rod is reversed to move it away from the vertical groove, so that the positioning rod leaves the inner wall of the vertical groove. At this time, the positioning ring 14 can be pulled downward to separate it from the rotating shaft 10, and then the ring plate 12 can be separated from the rotating shaft 10, and the rubber pad 13 can be torn off for replacement. Then the ring plate 12 and the positioning ring 14 can be reset, and the positioning rod is turned forward to make it contact with the inner wall of the vertical groove, so that the positioning ring 14 cannot move, thereby completing the replacement of the rubber pad 13.

[0032] like Figure 4 As shown, a chamfer is provided on one side of the stop block 20 close to the transverse plate 16 , and one side of the stop block 20 contacts the limiting plate 18 .

[0033] The stopper 20 can only rotate in the reverse direction but cannot rotate in the forward direction.

[0034] like Figure 1 As shown, the tuning component 5 corresponds to the position of the user's cheek.

[0035] This ensures that after the adjustment is completed, when the user blows air into his mouth, it can come into contact with the tuning component 5, thereby triggering the tuning component 5.

[0036] like Figure 1 As shown, the slide plate 2 will not fall off the slide opening when sliding along the slide opening.

[0037] This can prevent the slide plate 2 from being separated from the helmet 1 when the slide plate 2 is pulled out of the helmet 1 .

[0038] Working principle: When in use, the bolt 3 on one side is rotated forward at the same time to make the tuning component 5 move toward the outside of the helmet 1, so that the distance between the pair of tuning components 5 is adjusted to adapt to the user's cheek, and the tuning component 5 is adjusted to fit the cheek. During riding, when a call comes in, the tuning component 5 is triggered by blowing air on the cheek to cooperate with the mobile phone Bluetooth to connect the call, and the conversation is carried out through the earphone component 4, so that the call can be answered automatically. When it is necessary to take off the helmet 1, both hands are placed on both sides of the helmet 1, and the two thumbs press the outer rod 8 respectively to make it move with the inner rod 7, the baffle 6 and the skateboard 2, and at the same time, the shaft 10 rotates to make the first torsion spring 11 The torsional deformation generates a force, and as the slide plate 2 moves, the pair of slide plates 2 moves away from each other, thereby moving the bolt 3 and the tuning assembly 5, so that the tuning assembly 5 moves away from the cheek of the user, and then the helmet 1 is pulled upward to separate the helmet 1 from the user's head. In the process of separation, the tuning assembly 5 is away from the cheek of the user, so that the tuning assembly 5 does not generate friction with the cheek of the user, so that when the helmet 1 is taken off, the tuning assembly 5 does not cause discomfort to the cheek. After taking off the helmet 1, the outer rod 8 can be loosened, and the first torsion spring 11 releases the force to rotate and reset the shaft 10 and the outer rod 8. Conversely, the slide plate 2 can be reset, so that the tuning assembly 5 is reset;When the thumb presses the outer rod 8, the rotating shaft 10 at this time rotates with the movable block and the ring plate 12, so that the cross plate 16, the bottom plate 17, the circular shaft 19, and the stop block 20 rotate accordingly. After the stop block 20 contacts the arc surface, it cannot rotate forward due to the existence of the limit plate 18. The stop block 20 moves along the arc surface, causing it to descend, thereby causing the circular shaft 19, the bottom plate 17, the horizontal plate 16, the ring plate 12 and the rubber pad 13 to descend, so that the rubber pad 13 leaves the side plate 9. At the same time, the movable block squeezes the spring 15 to deform it to generate a force, so that the rubber pad 13 leaves the side plate 9. Therefore, when the outer rod 8 is pressed to make the skateboard 2 move outside the helmet 1, the rubber pad 13 does not contact the side plate 9 during this process, so that the rubber pad 13 will not be worn, and the rubber pad 13 can be protected. When the outer rod 8 is pressed to the point where it cannot move, the stop block 20 is separated from the driving block 22. At this time, under the action of the spring 15, the movable block, the ring plate 12 and the rubber pad The rubber pad 13 is reset, so that the rubber pad 13 contacts the side plate 9. When the helmet is pulled upward, if it is accidentally dropped from the hand, the first torsion spring 11 causes the rotating shaft 10 and the outer rod 8 to rotate and reset. On the contrary, the stop block 20 moves accordingly. After the stop block 20 contacts the driving block 22, the stop block 20 reverses with the round shaft 19, and at the same time, the second torsion spring torsional deformation generates a force, so that in the process of rotating and resetting the rotating shaft 10, the rubber pad 13 always contacts the side plate 9, so that the rotation speed of the rotating shaft 10 can be slowed down by friction, so that the rotating shaft 10 can be rotated slowly, and the outer rod 8 can be rotated and reset slowly, so as to avoid the outer rod 8 from causing the inner rod 7 to collide with the helmet 1 and generate vibration when the outer rod 8 is quickly reset, and the vibration is transmitted to the tuning assembly 5, so that the tuning assembly 5 can be protected after it is dropped from the hand. When the stop block 20 is separated from the driving block 22, the second torsion spring releases the force to rotate and reset the round shaft 19 and the stop block 20. ;

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
