Fig. 1 is an exploded view of an opening and closing mechanism according to an embodiment of the present invention, as shown in fig. 1. The embodiment of the invention provides an opening and closing mechanism of wearable equipment, which comprises the following components: the device comprises a shell 10, a connecting piece 20 and an elastic component 30.
Wherein, the casing 10 includes a receiving cavity, a first limiting structure and a second limiting structure are disposed in the receiving cavity, and the connecting member 20 and the elastic component 30 are disposed in the receiving cavity.
Referring to fig. 2 and 3, one end of the connection member 20 is rotatably connected to one end of the housing 10, and the other end of the connection member 20 is rotatably connected to one end of the elastic member 30; the other end of the elastic member 30 is rotatably connected with the other end of the housing 10.
Referring to fig. 2, when the connecting member 20 is in the first state, the connecting member 20 abuts against the first limiting structure, an included angle is formed between the axis of the connecting member 20 in the length direction and the axis of the elastic assembly 30 in the length direction, and the elastic assembly 30 fixes the connecting member 20 in the first state.
Referring to fig. 3, when the connecting member 20 is in the second state, the connecting member 20 abuts against the second limiting structure, the axis of the connecting member 20 in the length direction and the axis of the elastic assembly 30 in the length direction are located on the same line, and the elastic assembly 30 fixes the connecting member 20 in the second state.
With specific reference to fig. 2 and 3, the transition between the first and second states of the connector 20 is accomplished by rotating the connector 20 about the end of the connector 20 that is connected to the housing 10. The end of the connection member 20 connected to the housing 10 is defined as a first end, and the end of the connection member 20 connected to the elastic member 30 is defined as a second end.
When the first end is in contact with the first limiting structure, the opening and closing mechanism is in the first state, the elastic component has a pre-pressure of a reaction force, and a continuous force is generated to enable an included angle (the opening and closing mechanism is in a closed state) to be formed between the axis of the connecting piece 20 in the length direction and the axis of the elastic component 30 in the length direction.
When an external force acts on the connecting piece 20, the relative position of the first end and the shell 10 is kept motionless, the second end rotates around the first end, when the second end is abutted with the second limiting structure, the opening and closing mechanism is in a second state, the elastic component 30 has the pre-compression of the reaction force, and the continuous force can enable the axis of the connecting piece 20 in the length direction and the axis of the elastic component 30 in the length direction to be positioned on the same straight line. At this time, the opening and closing mechanism is at the maximum opening angle of opening. As long as no external force acts on the opening and closing mechanism, the opening and closing mechanism can keep balance in an opening state all the time. When the connecting piece 20 has external force, the balance of the force between the connecting piece 20 and the elastic component 30 is broken, and the opening and closing mechanism automatically returns to the first state from the second state under the action of the elastic component 30.
According to the technical scheme provided by the embodiment of the invention, when the connecting piece 20 is in the first state, an included angle is formed between the axis of the connecting piece 20 in the length direction and the axis of the elastic component 30 in the length direction, and at the moment, the opening and closing mechanism is in the closed state. When the connector 20 is in the second state, the axis of the connector 20 in the length direction and the axis of the elastic component 30 in the length direction are on the same line, and at this time, the opening and closing mechanism is in the closed and open state. The connecting member 20 is in the first state and the second state, and applies pressure to the elastic assembly 30, and the elastic assembly 30 can fix the connecting member 20 in the first state or the second state by restoring force. The opening and closing mechanism is widely applied, and can be used between two parts needing to be opened and closed, for example, can be applied to opening and closing between an earphone and a host of VR (virtual reality) headset.
The opening and closing mechanism provided by the invention is described in further detail below.
With continued reference to fig. 1-3, in one possible embodiment of the present invention, a first rotational shaft 13 and a second rotational shaft 14 are disposed within the housing 10; one end of the connecting piece 20 is sleeved on the first rotating shaft 13 and is rotatably connected with the shell 10, and the other end of the elastic component 30 is sleeved on the second rotating shaft 14 and is rotatably connected with the shell 10.
For example, referring to fig. 4, the housing 10 has two side walls 11, and the two side walls 11 are provided with corresponding shaft holes for mounting the first rotation shaft 13 and the second rotation shaft 14. The first rotation shaft 13 and the second rotation shaft 14 are disposed between the two side walls 11. The connecting piece 20 and the elastic component 30 are arranged between the two side walls 13, the connecting piece 20 is sleeved on the first rotating shaft 14 and is rotatably connected with the two side walls 11, and the elastic component 30 is sleeved on the second rotating shaft 14 and is rotatably connected with the two side walls 11. To prevent the link 20 from moving back and forth in the axial direction of the first rotation shaft 12, the width of the link 20 matches the distance between the two side walls 11. Specifically, the width of the connector 20 may be slightly smaller than the distance between the two side walls 11 to facilitate rotation of the connector 20.
In an embodiment of the present invention, the implementation manners of the first limiting structure and the second limiting structure include a plurality of implementation manners, where, with continued reference to fig. 2 and fig. 3, in an embodiment of the present invention, the connecting piece 20 is located between the first limiting structure and the second limiting structure. The first limiting structure is a limiting inclined block 15, and the limiting inclined block 15 is arranged at one end of the shell 10, which is close to the connecting piece 20. The second limiting structure is a limiting plate 12, and the limiting plate 12 is arranged at a position on the shell 10 opposite to the first limiting structure. The limiting inclined block 15 and the limiting plate 12 are located on the rotation paths of the connecting piece 20 in different rotation directions so as to limit the rotation amplitude of the connecting piece 20 and further limit the state of the connecting piece 20.
Specifically, when the connecting member 20 is in the first state, the connecting member 20 abuts against the inclined surface of the limiting inclined block 15. At this time, the elastic component 30 and the limiting inclined block 15 form an extrusion structure against the connecting piece 20, and the elastic component 30 fixes the connecting piece 20 in the first state. The limiting inclined block 15 has an inclined plane, and the size of the included angle between the connecting piece 20 and the elastic component 30 can be limited by the inclined plane of the limiting inclined block 15. When the connecting piece 20 is in the second state, the connecting piece 20 abuts against the limiting plate 12, and the axis of the connecting piece 20 in the length direction is parallel to the connecting plate 12. At this time, the elastic member 30 forms a pressing structure against the connection member 20 with the first rotation shaft 12, and the elastic member 30 fixes the connection member 20 in the second state.
Another way of realizing the first limiting structure and the second limiting structure is that a limiting part is arranged on the connecting piece 20, and the first limiting structure and the second limiting structure are both arranged on the first rotating shaft 12. When the connecting piece 20 is in the first state, the limiting part is abutted with the first limiting structure. When the connecting piece is in the second state, the limiting part is abutted with the second limiting structure.
For example, the limiting portion is a protrusion along the width direction of the connecting member 20. The first limiting structure and the second limiting structure are straight rods with axes perpendicular to the first rotating shaft, an included angle is formed between the two straight rods, and the bulge is located between the two straight rods. The protrusion moves between the two straight bars when the connector 20 rotates relative to the first rotation axis 12. For example, when the connecting member 20 rotates clockwise, after the protrusion abuts against the straight rod of the first limiting structure, the connecting member 20 cannot rotate clockwise, and when the connecting member 20 is in the first state, the elastic component 30 and the straight rod of the first limiting structure form a pressing structure on the connecting member 20, and the elastic component 30 fixes the connecting member 20 in the first state. Correspondingly, when the connecting piece 20 rotates anticlockwise, after the protrusion abuts against the straight rod with the second limiting structure, the connecting piece 20 cannot continue to rotate anticlockwise, and when the connecting piece 20 is in the second state, the elastic component 30 and the straight rod with the second limiting structure form an extrusion structure for the connecting piece 20, and the elastic component 30 fixes the connecting piece 20 in the second state.
With continued reference to fig. 1-3, in one embodiment of the present invention, the elastic assembly 30 includes a first slider 31, a second slider 32, and a spring 33. The first slider 31 is provided with a first accommodating groove along a length direction, the second slider is provided with a second accommodating groove along the length direction, and the first accommodating groove and the second accommodating groove are arranged opposite to each other. The first slider 31 is rotatably connected to the connecting member 20 through an end facing away from the bottom of the first accommodating groove. The second slider 32 is rotatably connected to the housing 10 by an end facing away from the bottom of the second receiving groove. Both ends of the spring 33 are respectively located in the first accommodating groove and the second accommodating groove, and form pre-compression on the first sliding block 31 and the second sliding block 32.
Specifically, referring to fig. 2 to 5, the connector 20 is rotatably coupled to the housing 10 by being sleeved on the first rotating shaft 13 (one end of the connector 20 sleeved on the first rotating shaft 13 is not shown in fig. 5), the elastic component 30 is rotatably coupled to the housing 10 by being sleeved on the second rotating shaft 14 through the second slider 32, and the elastic component 30 is rotatably coupled to the connector 20 through the first slider 31. The first slider 31 abuts on the connection member 20 under the urging force of the spring 33.
Referring to fig. 2, 3 and 6, in one embodiment of the present invention, a connecting groove 21 is provided at an end of the connecting member 20 facing the first slider 31, a third rotation shaft 22 is provided in the connecting groove 21, and the first slider 31 extends into the connecting groove 21 and is sleeved on the third rotation shaft 22. When the connecting piece 20 is switched between the first state and the second state, the first sliding block 31 and the connecting piece 20 can rotate relatively, so that the rotation is smoother, one end of the connecting piece 20, which faces the first sliding block 31, is in a circular arc shape, and one end of the first sliding block 31, which faces the connecting piece 20, is in a groove matched with the circular arc shape.
The first slider 31 and the second slider 32 are moved away from and toward each other when the opening and closing mechanism is switched between the first state and the second state. When the first slider 31 and the second slider 32 are close to each other, if the first slider 31 and the second slider 32 abut against each other, there is a possibility that the connection member 20 is unstable in the first state and the second state. In order to prevent the first slider 31 and the second slider 32 from abutting against each other, one solution is that the first slider 31 is sleeved in the second accommodating groove, or the second slider 32 is sleeved in the first accommodating groove, and the first slider 31 and the second slider 32 can slide each other. Meanwhile, the first slider 31 and the second slider 32 which are sleeved with each other can also prevent the spring 33 from bending when in use.
Another solution is to have a gap between the first slider 31 and the second slider 32. With this gap, when the first slider 31 and the second slider 32 come close to each other, the first slider 31 and the second slider 32 can be prevented from abutting each other.
When the gap between the first slider 31 and the second slider 32 is formed, the spring 33 is easily bent at the gap, which affects the normal use of the elastic assembly 30, and in order to prevent the bending of the spring 33, with continued reference to fig. 1, the elastic assembly further includes a guide rod 34. The spring 33 is sleeved on the guide rod 34 to avoid bending of the spring 33. One way of arranging the guide rod 34 is that one end of the guide rod 34 is fixed in the first accommodation groove or the second accommodation groove, and the other end extends into the other accommodation groove along with the spring 33.
Another arrangement mode of the guide rod 34 is that, referring to fig. 1 and 6, one end of the guide rod 34 is provided with a connecting part 35, and the bottom of the first accommodating groove is provided with a through hole; the other end of the guide rod 34 passes through the first sliding block 31 from the through hole and stretches into the second accommodating groove; the spring 33 is sleeved on the guide rod 34; the first slider 31 is rotatably connected to the connection member 20 through a connection portion 35. Further, the connection portion 35 of the guide bar 34 is located in a hook-like structure or a loop-like structure. The guide rod 34 may be hooked on the third rotation shaft 22 by a hook structure or may be sleeved on the third rotation shaft 22 by a loop structure.
With continued reference to fig. 1, to prevent non-axial movement of the spring 33 on the guide rod 34, a sliding sleeve 36 is disposed between the guide rod 34 and the spring 33, the sliding sleeve 36 is sleeved on the guide rod 34, and the spring 33 is sleeved on the sliding sleeve 36. Specifically, the outer diameter of the sliding sleeve 36 is matched with the inner diameter of the spring 33, and the spring 33 does not move in a non-axial direction after being sleeved on the sliding sleeve 36, so that the axial output elastic force of the spring 33 is more stable.
With continued reference to fig. 3, in one embodiment of the present invention, an avoidance channel 37 is disposed at the bottom of the second accommodating groove along the length direction of the second accommodating groove, and when the connecting member 20 is switched from the first state to the second state, one end of the guide rod 34 extending into the second accommodating groove extends into the avoidance channel 37.
