The wire take-up device will be described in detail below with reference to FIGS. 2 to 4 .

The take-up pulley 200 is in the shape of a dome, and an inner chamber for accommodating the coil spring 110 is formed inside, and a plurality of wire clamping grooves 201 are arranged on its side wall. Two wires 410, 420 respectively pass through two wire outlets 103 on the wall of the take-up box, one wire 420 directly enters the inner chamber of the take-up reel 200 from the slot 201 on the side of the take-up reel 200, and the other wire 410 passes through two The steering wheels 120, 130 change direction twice, and the direction opposite to the last lead 420 enters the inner cavity from the side of the take-up wheel.

The steering wheel 130 is freely rotatably mounted on the shaft 107 , and the steering wheel 120 is freely rotatably mounted on the shaft 105 . One end of the coil spring 110 is fixed in the gap 1011 of the shaft 101 of the take-up box 10 , and the other end is hooked in the slot 201 of the side wall of the take-up wheel 200 to be fixed. The take-up reel 200 takes the shaft 101 as the center of rotation, and one end of the coil spring 110 is fixed on the gap 1011 of the shaft 101, and the other end is fixed on the side wall of the take-up reel 200. In the state of unwinding, the external force pulls the earphone feeder to drive The take-up reel rotates, and the helical spring is compressed while the take-up reel rotates, thereby storing elastic potential energy for the take-up.

The conductive core wires of the two wires 410, 420 are respectively connected to the corresponding metal sheets 230, 240, and the connection can be realized by welding. The extended part of the metal sheet 230, 240 on the side wall of the take-up reel can be fixed on the side wall of the take-up reel 200 in an embedded manner, and the part extending on the bottom surface of the inner cavity of the take-up reel 200 can be fixed on the side wall of the take-up reel 200 by hot ironing. bottom of the wheel well.

Metal sheet 230,240 is electrically connected with the elastic contact piece 210,220 of electric brush again, and the annular contact piece 250,260 of electric brush is static with respect to lid 30, and elastic contact piece 210,220 follows take-up wheel 200 Relatively rotatable, in this way, during the rotation process of the take-up reel 200, due to the elasticity of the elastic contact pieces 210, 220, the elastic contact pieces 210, 220 always keep in contact with the annular contact pieces 250, 260. Therefore, the core wires of the wires 410, 420 are electrically connected to the pins 251, 261 through the metal sheets 230, 240 and the brush.

Fig. 5 shows a top view of the wire take-up wheel of the wire take-up device shown in Fig. 1 . As shown in FIG. 5 , the wire take-up reel 200 includes a wire release slot 206 , a wire release slot 204 and a wire collection slot 202 , wherein the wire release slot 204 and the wire collection slot 202 merge into the wire release slot 206 at the transition section 2014 . The holes 2010 and 2012 provided on the take-up reel 200 are used for installing the elastic contacts 210 and 220, and the central hole 2016 is used for placing fixing parts, such as screws. The relationship between the heights of the three surfaces indicated by the symbols A, B, and C in the figure is that the A surface is higher than the B surface, and the B surface is higher than the C surface.

FIG. 6 shows the rear cover 30 of the wire take-up device shown in FIG. 1 . As shown in the figure, the rear cover 30 is provided with positioning holes 301, 303 and a central hole 305, wherein the positioning holes 301, 303 are used for the positioning of the pins 251, 261, and the central hole 305 is used for the setting of screws, so as to connect the box Cover 30 and box body 10.

Fig. 7 shows an overall perspective view of the wire take-up device shown in Fig. 1 . As shown in the figure, the wires 410, 420 are located on one side of the box body 10, and the pins 251, 261 extend out of the box cover 30, and can be connected to the feeder wire at one end of the earphone plug or directly connected to the audio output port. The ring-shaped sheet metal ears can be fixed on the lid by methods such as hot stamping.

In other alternative embodiments, the ring-shaped metal sheet of the brush can be arranged on the pay-off wheel, and correspondingly, the elastic contact piece is arranged on the box cover.

In the above preferred embodiment, there are two wires, each wire only includes one core wire, and each core wire corresponds to a pair of elastic contacts and ring-shaped metal sheets on the brush. In other alternative embodiments, each wire may include at least two core wires, and each core wire corresponds to a pair of elastic contact pieces and an annular metal piece on the brush. In other alternative embodiments, only one wire may be included, and the wire may include more than two core wires, and each core wire corresponds to a pair of elastic contact pieces and ring metal pieces on the brush, so that the use of Based on the wire-guided guide wheel, the structure of the wire take-up device is simplified.

The following describes the wire take-up action and the wire release action of the wire take-up device with reference to FIGS. 1 to 7 .

Because the guide groove is designed in the form of a cam, so when the take-up wheel turns to a certain position, the take-up wheel cannot rotate because the ball is stuck between the line take-up wheel and the box cover.

Take-up action: In the take-up state, the coil spring returns to the free state due to elasticity, driving the take-up wheel to rotate clockwise, and the ball that acts as a limiter is in a non-stop guide groove of the take-up wheel (as shown in the figure Sliding in the shown wire receiving groove 202).

Pay-off action: In the pay-off state, the external force pulls the feeder, drives the take-up wheel to rotate counterclockwise, and tightens the coil spring by torsion. There are two situations when paying out the wire: if it is pulled until the feeder is exhausted, the ball moves in a section of the pay-off slot of the take-up wheel (ie, the pay-out slot 206 shown in the figure); , and then continue to pay off, so repeatedly, then the ball moves in another section of the wire slot (ie, the wire slot 204 shown in the figure).

When the ball was in the transition section, because the ball was stuck between the take-up wheel and the box cover, the take-up wheel could not rotate due to friction, and the pay-off could be paused (position B in the figure).

The ball can move from the guide groove of the transition section to the guide groove when taking up the line, so that it can transition to the take-up state from any pause position of paying off the line. (When the ball is at position B, the take-up wheel reverses a small angle and then rotates clockwise, which can transition from B to C in the figure).

The overall take-up box according to the preferred embodiment of the utility model can be fixed on audio-visual products such as mobile phones and walkmans.

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications, changes and omissions. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
