In order to better understand the above technical solutions, the following describes the above technical solutions in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a strap tightness adjustment mechanism, including:
a housing 100, the interior of which forms a mounting cavity;
an adjusting wheel 600 disposed outside the housing 100 and rotatably connected to the housing 100;
the clutch assembly 200 is slidably arranged in the mounting cavity and is in driving connection with the adjusting wheel 600;
the key 300 is arranged outside the shell 100 and is movably connected with the shell 100, and the key 300 drives the clutch assembly 200 to slide so as to move from a first position to a second position;
the driving assembly 400 is arranged at one side of the adjusting wheel 600 and drives the clutch assembly 200 to slide so as to move from the second position to the first position; in the first position, the driving assembly 400 is in driving connection with the adjustment wheel 600 to drive the adjustment wheel 600 to rotate bidirectionally, and in the second position, the driving assembly 400 is disconnected from the adjustment wheel 600.
In the technical scheme adopted in this embodiment, by pressing the key 300 disposed on the housing 100, the clutch assembly 200 moves, that is, the clutch assembly 200 moves from the first position to the second position, at this time, the adjusting wheel 600 is disconnected from the driving assembly 400, and the user manually rotates the adjusting wheel 600 to loosen the tightness of the binding band, so that the binding band is conveniently worn on the head or the wrist. After wearing, the driving assembly 400 works to drive the clutch assembly 200 to move from the second position to the first position, and at the moment, the driving assembly 400 is in driving connection with the adjusting wheel 600 to drive the adjusting wheel 600 to rotate bidirectionally, so that the tightness of the binding belt is automatically adjusted. The strap tightness adjusting mechanism provided by the embodiment replaces manual adjustment of both hands of a user, achieves automatic tightening or loosening of the strap in the using process of the wearable equipment, and is simpler and more convenient than manual operation.
Specifically, the strap tension adjustment mechanism includes a housing 100, an adjustment wheel 600, a clutch assembly 200, a key 300, and a drive assembly 400. The interior of the housing 100 forms a mounting cavity in which the clutch assembly 200 and the drive assembly 400 are disposed, wherein the clutch assembly 200 is slidably disposed in the mounting cavity and is movable from a first position to a second position for connecting or disconnecting the force transmission between the adjustment wheel 600 and the drive assembly 400. It can be appreciated that when the clutch assembly 200 is in the first position, the driving force of the driving assembly 400 can be transmitted to the adjusting wheel 600 through the clutch assembly 200, so as to drive the adjusting wheel 600 to rotate, thereby conveniently adjusting the tightness of the binding band; when the clutch assembly 200 is at the second position, the driving assembly 400 is disconnected from the adjusting wheel 600, the adjusting wheel 600 can be manually rotated to loosen the binding band, so that a wearer can wear the wearable device on the head or the wrist conveniently, after the wearer wears the wearable device, the driving assembly 400 works to drive the clutch assembly 200 to move from the second position to the first position, and then the driving force is transmitted to the adjusting wheel 600 through the clutch assembly 200 to drive the adjusting wheel 600 to rotate, the tightness of the binding band is adjusted, and the comfort of the wearer is guaranteed. In an embodiment, a sensor may be further provided, the wearing pressure of the binding belt is detected in real time through the sensor, the wearing pressure signal detected by the sensor is transmitted to the controller, and after the controller is analyzed by a series of algorithms, the working state of the driving assembly 400 is controlled, so that the adjusting wheel 600 rotates clockwise or anticlockwise, and the tightness of the binding belt is adjusted until the wearing pressure signal is within a preset range. It should be noted that the key 300 is elastically connected to the housing 100, that is, pressing the key 300 makes the key 300 contact with the clutch assembly 200 and drives the clutch assembly 200 to move from the first position to the second position. After the clutch assembly 200 moves to the second position, the pressing force is removed, and the key 300 automatically returns. The specific structure of the key 300 can be referred to as the structure of the product commonly used in the market, and is not limited herein.
Further, referring to fig. 1, in an embodiment of the present invention, the driving assembly 400:
the rotating structure 410 is rotatably arranged in the mounting cavity, and in a first position, the rotating structure 410 is in driving connection with the adjusting wheel 600 to drive the adjusting wheel 600 to rotate bidirectionally, and in a second position, the rotating structure 410 is disconnected from the adjusting wheel 600;
the limiting structure 420 is slidably arranged in the mounting cavity, and in the process of moving the clutch assembly 200 from the first position to the second position, the limiting structure 420 moves from a third position to a fourth position, the limiting structure 420 locks the clutch assembly 200 to connect the rotating structure 410 and the adjusting wheel 600, and in the fourth position, the limiting structure 420 unlocks the clutch assembly 200 to enable the clutch assembly 200 to move to the second position; and
the transmission structure 430 is connected with the rotating structure 410 and the limiting structure 420, and the rotating structure 410 drives the limiting structure 420 to move from the fourth position to the third position through the transmission structure 430.
Specifically, the driving assembly 400 includes a rotating structure 410, a limiting structure 420, and a transmission structure 430. The rotating structure 410 is disposed in the mounting cavity, and is mainly used for providing driving force to drive the adjusting wheel 600 to rotate, thereby realizing automatic adjustment of tightness of the binding band. It will be appreciated that when the clutch assembly 200 is moved to the first position, the rotating structure 410 is connected to the clutch assembly 200, so that the driving force is transmitted to the adjustment wheel 600 through the clutch assembly 200 to drive the adjustment wheel 600 to rotate; when the clutch assembly 200 moves to the second position, the rotating structure 410 is disconnected from the clutch assembly 200, and the driving force of the rotating structure 410 cannot be transmitted to the adjusting wheel 600, so that the adjusting wheel 600 can be manually rotated, and the wearer can wear the wearable device on the head or the wrist conveniently. That is, the clutch assembly 200 is in driving connection with the adjustment wheel 600, whether in the first or second position. For the rotary structure 410, the clutch assembly 200 is in driving connection with the rotary structure 410 to transmit driving force when in the second position.
The limiting structure 420 is slidably disposed in the mounting cavity, and the sliding direction of the limiting structure 420 is perpendicular to the sliding direction of the clutch assembly 200. It will be appreciated that the spacing structure 420 may slide in a horizontal direction and the clutch assembly 200 may slide in a vertical direction. When the limiting structure 420 slides to the third position, the limiting structure 420 is abutted with the side wall of the clutch assembly 200, i.e. the limiting structure 420 is positioned at one side of the sliding direction of the clutch assembly 200, the limiting structure 420 is abutted with the clutch assembly 200, at this time, the clutch assembly 200 is positioned at the first position and is in driving connection with the rotating structure 410, and the rotation of the rotating structure 410 drives the clutch assembly 200 to rotate synchronously, so as to drive the adjusting wheel 600 to rotate. When the limiting structure 420 slides to the fourth position, the limiting structure 420 is located at one end of the clutch assembly 200 along the sliding direction, i.e. one end away from the adjusting wheel 600, and at this time, the clutch assembly 200 moves to the second position and is separated from the driving structure, and the rotating structure 410 cannot drive the clutch assembly 200 to rotate, so that the adjusting wheel 600 cannot be driven to rotate.
The transmission structure 430 is configured to drive the limiting structure 420 to slide from the fourth position to the third position, and it can be appreciated that when the clutch assembly 200 moves to the second position, the rotation structure 410 rotates, and the limiting structure 420 is driven to move from the fourth position to the third position by the transmission structure 430. When the limiting structure 420 moves to the third position, a space for the clutch assembly 200 to move away from the adjusting wheel 600 is formed on the side of the clutch assembly 200 away from the adjusting wheel 600, and the clutch assembly 200 can move from the second position to the first position under the action of self gravity or an elastic element.
Further, referring to fig. 2, 3, 9 and 10, in an embodiment of the present invention, the limiting structure 420 includes:
a limit slider 421 slidably disposed within the mounting cavity to switch between a third position and a fourth position;
the first elastic reset piece 422 is connected with the limit sliding block 421 and the shell 100; and
a second elastic restoring member 423 connecting the clutch assembly 200 and the housing 100;
in the third position, the limiting slider 421 is abutted against the outer periphery of the clutch assembly 200 through the first elastic restoring member 422 to limit the clutch assembly 200 from sliding; in the process of moving the clutch assembly 200 from the first position to the second position, the limit slider 421 slides from the third position to the fourth position under the driving of the first elastic reset piece 422; in the process of moving the limit slider 421 from the fourth position to the third position, the clutch assembly 200 moves from the second position to the first position under the action of the second elastic restoring member 423.
Specifically, the limiting structure 420 includes a limiting slider 421, a first elastic restoring member 422, and a second elastic restoring member 423. The limiting slider 421 is slidably disposed in the mounting cavity and can slide between a third position and a fourth position. The first elastic restoring member 422 is connected with the limit slider 421 and the housing 100, when the limit slider 421 is at the third position, the clutch assembly 200 is at the first position, and the first elastic restoring member 422 deforms to generate an elastic force, so that the limit slider 421 abuts against the side wall of the clutch assembly 200. In the process that the clutch assembly 200 moves towards the second position under the action of the key 300, the limit slider 421 moves towards the fourth position from the third position under the action of the elastic force of the first elastic reset element 422 to abut against the end of the clutch assembly 200, and the movement of the limit slider 421 towards the third position from the fourth position is driven by the rotation structure 410 through the transmission structure 430. In addition, the second elastic restoring member 423 connects the clutch assembly 200 and the housing 100, and when the clutch assembly 200 moves from the first position toward the second position, the second elastic restoring member 423 deforms to generate an elastic force. During the movement of the limit slider 421 from the fourth position toward the third position, the clutch assembly 200 moves from the second position toward the first position under the elastic force of the second elastic restoring member 423. After the clutch assembly 200 moves to the first position, the limit slider 421 abuts against the side wall of the clutch assembly 200, and due to the cooperation of the first elastic restoring member 422 and the second elastic restoring member 423, the clutch assembly 200 and the rotating structure 410 maintain a fixed state, so that the driving force of the rotating structure 410 is transmitted to the adjusting wheel 600.
