Because the wire harness 350 is wound in the first wire winding groove 333 and the second wire winding groove 334 respectively, the wire harness 350 is limited by the first wire winding groove 333 and the second wire winding groove 334, the position is stable, the axial folding, the rolling and the loosening are not easy to occur, and when the wire winding bracket 330 and the wire harness 350 are assembled into the shell 310, the wire harness 350 cannot interfere with the second half shell 312, so that the second half shell 312 is convenient to fix on the first half shell 311.
It should be noted that, the winding bracket 330 is configured as an integral structure, for example, a mold can be used for integrally forming, the processing is convenient, the batch production is suitable, the processing difficulty is reduced, the structural strength of the integral structure is improved, and the service life is long.
Referring to fig. 11-13, in this embodiment, optionally, a unidirectional damping assembly 360 includes a mounting shaft 361 and a damping mass 362. The mounting shaft 361 is fixed to the protective cap 315, and an axis of the mounting shaft 361 extends in a radial direction of the first half shell 311, that is, the mounting shaft 361 is disposed perpendicular to the rotation shaft 320. The damping block 362 includes an integral body 3621 and a convex body 3622, the body 3621 is square, the body 3621 has a first side 3623, a second side 3624, a third side 3625 and a fourth side 3626 which are connected end to end in sequence, the first side 3623 is opposite to the third side 3625, the second side 3624 is opposite to the fourth side 3626, and a chamfer is disposed at the connection between the second side 3624 and the third side 3625, in other words, the first side 3623 is connected with the third side 3625 by an avoidance slope 3628, the avoidance slope 3628 can be a cambered surface or a plane, and the avoidance slope 3628 has an included angle with the first side 3623 and the third side 3625. Second side 3624 is provided as a damping surface, for example, second side 3624 may be provided as a roughened surface. The convex body 3622 is disposed on the first side 3623, and a side of the convex body 3622 adjacent to the second side 3624 is spaced apart from the second side 3624, and a side of the convex body 3622 adjacent to the second side 3624 may be referred to as a blocking surface 3629. The body 3621 is provided with a rotation hole 3627, the rotation hole 3627 is a circular hole, a distance between an axis of the rotation hole 3627 and the first side 3623 is L1, a distance between an axis of the rotation hole 3627 and the third side 3625 is L2, L2 is larger than L2, and a distance between an axis of the rotation hole 3627 and the second side 3624 is larger than a distance between an axis of the rotation hole 3627 and the fourth side 3626, so that when the damper block 362 is rotatably connected with the rotation shaft, the damper block 362 is eccentrically disposed with the rotation shaft, the second side 3624 of the damper block 362 contacts with a plate surface of the first plate 3314 away from the second plate 3315, and a side of the damper block 362 corresponding to the first side 3623 has a tendency to rotate toward the first plate 3314 under the action of gravity, thereby enabling the second side 3624 to always contact with the first plate 3314. meanwhile, the rotation trend of the damping block 362 corresponds to the rotation direction of the winding bracket 330, that is, when the winding bracket 330 rotates in the first rotation direction 001, at this time, the wire harness 350 is wound around the winding bracket 330, and under the friction force of the damping surface and the first disk 3314, there is a trend of continuously pressing the damping surface against the first disk 3314, and the view angles shown in fig. 12 and 13 are taken as references, that is, the damping surface has a clockwise rotation trend, the force of pressing the damping surface against the first disk 3314 increases, the friction force increases, and the rotation speed of the winding bracket 330 decreases. When the wire harness 350 is pulled to rotate the wire winding bracket 330 in the second rotation direction 002, at this time, the wire harness 350 is unwound, the wire harness 350 is lengthened, and the damping block 362 has a counterclockwise rotation tendency, so that the damping surface is separated from the first disk 3314, and the friction force to the first disk 3314 is reduced, thereby not affecting the wire harness 350 pulling-out operation. Meanwhile, due to the design of the avoidance inclined surface 3628, when the damping block 362 rotates anticlockwise under the drive of the first disk body 3314, the avoidance inclined surface 3628 is not easy to contact with the first disk body 3314, the contact area of the damping block 362 and the first disk body 3314 is reduced, and therefore the resistance of the damping block 362 on the first disk body 3314 is also reduced, and the wire harness 350 is conveniently pulled out. In other words, through the structural design of the unidirectional damping block 362, when the wire harness 350 is recovered by the wire winding bracket 330 under the action of the coil spring 340, the rotation speed of the wire winding bracket 330 is reduced, the generated torque is small, the force of the wire harness 350 on the hand of the user is small, and the user experience is better. Wherein the first rotational direction 001 is opposite to the second rotational direction 002.
Meanwhile, when the damping block 362 is mounted in the mounting hole 3113, the protruding body 3622 is located on a side of the limiting structure away from the second half shell 312, and the blocking surface 3629 has a distance from the limiting structure. When the winding bracket 330 rotates along the first rotation direction 001 to retract the wire harness 350, the damping block 362 is driven by the first disk body 3314 to rotate towards the direction of compacting the first disk body 3314, and the blocking surface 3629 can be abutted with the limiting structure, so that the rotation angle of the damping block 362 in the rotation direction of compacting the first disk body 3314 is limited, the condition that the damping block 362 is blocked with the first disk body 3314 is avoided, and the safety is improved.
The working principle of the intelligent body fat scale provided by the embodiment is as follows:
When the handle 200 is set to be in the initial state, the handle 200 is embedded in the positioning groove 161, and the handle 200 is matched with the first buckle 162 and the second buckle 210 to realize positioning, so that the positioning is firm and reliable, and the automatic loosening is not easy. When the wire harness pulling device is required to be used, the handle 200 is taken out from the positioning groove 161, and force is applied to the handle 200, so that the handle 200 drives the wire winding bracket 330 to rotate along the second rotation direction 002 through the wire harness 350, and the damping block 362 can rotate in the anticlockwise direction, so that the resistance to the first disk 3314 is reduced, namely the damping to the wire winding bracket 330 is reduced, the wire harness 350 is not interfered by the damping block 362 basically when being pulled out, and the pulling operation is time-saving and labor-saving. When the wire harness 350 needs to be recovered, the user withdraws the external force applied to the handle 200, the wire winding bracket 330 rotates along the first rotation direction 001 under the action of the coil spring 340, the wire harness 350 is automatically wound in the first wire winding groove 333 and the second wire winding groove 334, and under the action of the damping block 362, the damping block 362 always keeps close contact with the first disk 3314, a certain friction force for preventing the wire winding bracket 330 from rotating along the first rotation direction 001 is provided, so that the rotation speed of the wire winding bracket 330 in the process of recovering the wire harness 350 is small, and the user experience is improved.
