The two ends of the torsion spring 300 are respectively fixed to the rotary assembly 200 and to the cover 500. Thereby, the torsion spring 300 is fixed into the rotary assembly 200. A wire hole 150 is defined on the housing 100 whereby the wire 20 is drawn out or rewound in the housing 100. The rotary assembly 200 rotates along a first direction when the wire 20 is drawn out of the housing 100 through the wire hole 150, and the torsion spring 300 elastically deforms and stores a certain amount of potential energy. When the wire 20 needs to be rewound, the torsion spring 300 gradually releases this energy to drive the rotary assembly 200 to rotate along a second direction opposite to the first direction, thereby automatically rewinding the wire 20 into the housing 100. A fingertip, or other external force applied to the operation portion 430 drives the latching portion 140 to selectively lock or unlock the rotary assembly 200.
The housing 100 includes a base plate 110 and a sidewall 120 extending from an edge of the base plate 110. The latching portion 140 is a hollow cylinder extending from the base plate 110. The latching portion 140 includes a holding portion 143, a latching body 141, and a restriction portion 142. The holding portion 143 holds the latching body 141. The latching body 141 has a certain amount of flexibility to resist the rotary assembly 200 and lock the rotary assembly 200. The restriction portion 142 is defined on a top of the latching body 141. The rotary assembly 200 is sleeved over the latching body 141, and the restriction portion 142 restricts the vertical movement of the rotary assembly 200, thereby preventing the rotary assembly 200 from moving up and down and escaping from the latching body 141. In the embodiment, the latching body 141 is a wedge-shaped structure extending from an edge of the holding portion 143. The restriction portion 142 is a retaining wall extending from a top edge of the latching body 141 to the sidewall 120.
The rotary assembly 200 includes a base substrate 230 adjacent to the base plate 110, a positioning wall 250, and a wire winding portion 210. The wire winding portion 210 is a fat cylinder extending from the base substrate 230 to the cover 500. The positioning wall 250 is a hollow column extending from the base substrate 230. The base substrate 230, the wire winding portion 210 and the positioning wall 250 cooperate to define a receiving space for receiving the torsion spring 300. The base substrate 230 further defines a through hole 231 throughout the rotary assembly 200, in which the latching portion 140 and the operation portion 430 are received. The through hole 231 is surrounded by the positioning wall 250.
The positioning wall 250 is sleeved on the latching body 141 and the holding portion 143 and sandwiched between the base plate 110 and the restriction portion 142 of the latching portion 140, so that the rotary assembly 200 can rotate around the latching portion 140. In detail, when the latching body 141 is expanded by an external force applied to the latching body 141, the latching body 141 comes into contact with the positioning wall 250 of the rotary assembly 200, and friction between the latching body 141 and the internal surface of the positioning wall 250 locks the rotary assembly 200. Without an external force being applied to the latching body 141, the positioning wall 250 sleeved on the latching body 141 is free to rotate.
An annular groove is defined between the positioning wall 250 and the wire winding portion 210. The torsion spring 300 is sleeved on the positioning wall 250 and received in the annular groove, to cause the potential energy of the torsion spring 300 to rotate the rotary assembly 200 when the torsion spring 300 is released.
The operation portion 430 is received in an inner space defined by the latching body 141, the restriction portion 142, and the holding portion 143 of the latching portion 140. The operation portion 430 includes a button body 431 and an elastic member 433. The elastic member 433 is sleeved on and fixed to one end of the button body 431. In this embodiment, the button body 431 is connected to the base plate 110 via the elastic member 433. The button body 431 includes a protrusion 432 configured for pressing against and deforming the latching body 141 of the latching portion 140, to expand the latching body 141. The button body 431 can be a column-shaped roller. The protrusion 432 is defined at a middle portion of the roller.
In the embodiment, the wire winder 10 further includes a first location member 130, a second location member 131, and a through portion 435. The first location member 130 and the second location member 131 are positioned at opposite sides of the base plate 110, to sandwich the latching portion 140. The second location member 131 is adjacent to the wire hole 150. The first location member 131 and the second location member 132 are horizontally arranged on the base plate 110. The through portion 435 is fixed to the end of the operation portion 430 which is adjacent to the elastic member 433. The first location member 130, the second location member 131, and the wire hole 150 are arranged in a straight line.

In the embodiment, each of the first location member 130 and the second location member 131 includes a pair of location rollers 133. The two location rollers 133 define a clearance therebetween to allow the wire 20 to pass through. The pair of location rollers 133 of each of the first location member 130 and the second location member 131 contact with and clamp the wire 20. The clearance between the pair of location rollers 133 of the first location member 130 is narrower than the clearance between the pair of location rollers 133 of the second location member 130, so that friction between the wire 20 and the first location member 130 is greater than the friction between the wire and the second location member 131 during any pulling action applied to the wire 20. A portion of the wire 20 winds around one of the location rollers 133 of the first location member 130, passes through the through portion 435 and a gap between the two rollers 133 of the second location member 131, and extends out of the wire hole 150. In other embodiments, the second location member 131 can be omitted, and the wire channel is defined by the first location member 130, the through portion 435, and the wire hole 150.
The cover 500 includes an opening 510 to allow a portion of the button body 431 of operation portion 430 to protrude out of the housing 100 through the opening 510, thereby enabling a user to operate an exposed end of the operation portion 430.
In assembly of the wire winder 10, the rotary assembly 200 is sleeved on the latching portion 140 through the through hole 231, to make the latching portion 140 extend into the receiving space, and the positioning wall 250 to be received and sandwiched between the restriction portion 142 and the base plate 110. The operation portion 430 is fixed to the base plate 100 via the elastic member 433 and partly received in the inner space defined by the latching portion 140. Then, the torsion spring 300 is sleeved on the positioning wall 250, and one end of the torsion spring 300 is fixed to the rotary assembly 200. The wire 200 is wound around the wire winding portion 210 of the rotary assembly 200, and the outer end of the wire 20 is passed through the first location member 130, the through portion 435, and the second location member 131 and drawn out of the wire hole 150. Thereupon, the other end of the torsion spring 300 is fixed to the cover 500, and the cover 500 is secured on the top edge of the housing 100, with a top portion of the button body 431 passing through the opening 510 and protruding from the cover 500. After the wire winder 10 is assembled, a portion of the wire 20 has a bent portion near the through portion 435. At this time, the torsion spring 300 is not under tension and stores no potential energy.

When the pulling action on the wire 20 is stopped, the force applied to the wire 20 is eliminated, and the elastic member 433 restores to drive the protrusion 432 away from the base plate 110 to press against and deform the latching body 141 again, so that the latching body 141 latches with the positioning wall 250 to lock the rotary assembly 200 in that position and prevent further rotation.
When the wire 20 need to be rewound, the user simply presses the button body 431 to move the protrusion 432 again towards the base plate 100. The protrusion 432 thus detaches from the latching body 141, and the deformation of the latching body 141 ceases, to allow detachment of the latching portion 140 from the positioning wall 250, thereby unlocking the rotary assembly 200. Thereupon, the built-up potential energy of the torsion spring 300 is released to rotate the rotary assembly along the second direction to automatically rewind the wire 20 around the wire winding portion 210.
In other embodiments, the rotary assembly 200 may define a protruding structure extending from an inner side of the wire winding portion 210 to replace the positioning wall 250. The protruding structure cooperates with the latching portion 140 to lock the rotary assembly 200. In addition, the first location member 130 and the second member 131 may be defined at an inner surface of the cover 500 to define the wire channel for the wire 20. The two location rollers of each of the first location member 130 and the second member 131 can be replaced by a single location roller having a through hole.
Although numerous characteristics and advantages of the present embodiments have been set out in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only; and changes may be made in detail, especially in the matters of shape, size and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
