Detailed description of the invention
For making the purpose of this utility model, feature becomes apparent, and be further described, but the utility model can realize by different forms, should not think and just be confined to described embodiment below in conjunction with accompanying drawing to detailed description of the invention of the present utility model.
Embodiment one
As Figure 1-3, the present embodiment provides a kind of bracing wire automatic retracting mechanism, for furling earphone cord and carrying out spacing to earphone cord.
The design of the application comprises upper shell and the lower house of docking, the space of placing winding mechanism is formed between upper shell and lower house, the optimised form of the upper shell of the application and lower house design is open, can not form the form of closed and butted between upper shell and lower house.
Upper shell and lower house are designed to open, for enclosed, the restriction of wire rod being batched to length that enclosure space of can forgetting it brings, when same module size, can be applied to batching of the wire rod of various different-diameter and length.Such design saves the expense of die sinking injection moulding, reduces productive costs, and spare part unified by the earphone being applicable to different model, convenient for maintaining and warehouse-in statistics.
The winding mechanism of the application comprises a swivel, and swivel is by being arranged at rotating shaft on upper shell and upper shell is rotationally connected, and earphone cord from being wound is in the wire casing of swivel.
The volume of earphone is very little, and manufacturer makes every effort to the miniaturization of earphone unit design especially now, the space saved storage and wear.The module of the application is as the accessory of earphone, the volume of module is made every effort to simplify, so the best mode of the application is that such earphone cord can be accommodated in the I shape breach of swivel when take-up, saves the volume of whole module by the design of the vertical section of swivel in I-shape.
And the surface that the design of the application contacts with earphone cord in the wire casing of swivel is provided with the wiring groove that some groove axis directions along the line are evenly arranged.
General earphone cord spooler is all very mixed and disorderly when connecting up, the arrangement mode that earphone cord does not specify, if it is improper to batch power adjustment like this, earphone cord can produce the phenomenon that lamination is wound around when take-up, once lamination is wound, user is when pull earphone cord, the part that earphone cord is wound around at lamination will stretch, cause earphone cord to extract out, if do not open module, whole module will be scrapped.And fitfull winding can cause earphone cord each several part firmly uneven when receiving, and damage can be caused even to rupture to earphone cord for a long time like this, affect the service life of whole product.Earphone cord can be wound in uniformly on wire casing by the wiring groove of the application under the effect of the power of batching, decrease the random line phenomenon that lamination is wound around, improve the service life of earphone cord, and the earphone cord of evenly arrangement relative to irregular arrangement earphone cord shared by space greatly reduce, reduce further the volume of whole module.
In the technical scheme of the application, what provide rotary power for swivel is wind spring, and swivel is provided with wind spring groove, wind spring groove is a circular groove.
In the prior art, wind spring is generally arranged at outside swivel, and such design makes the volume of whole module, and particularly thickness increases much.But the coiled body of prior art is used for large-scale mechanical equipment, capacity issue is negligible in these fields, and another of wind spring mainly to apply be exactly as clockwork spring in mechanical watch, but due to precision requirement during the walking of mechanical watch, the design that this just wind spring is combined with miscellaneous part is not the principal contradiction that it designs.
In the design of the application, due in order to be wound around uniformly by earphone cord, so swivel is designed to I shape, a cavity will be formed in the inside of swivel like this, if wind spring is put into this cavity, a part of space can be saved on thickness.But due to higher for the requirement of batching power when batching earphone cord, the swivel inner space of I shape is less comparatively speaking, generally the wind spring of this kind of volume cannot provide enough and batch power.So due to this kind of structural limitations, the spring steel material that wind spring in the technical scheme of the application uses requires that yield tensile ratio is greater than 0.85, under relatively little volume, wind spring could provide enough rotary powers for swivel like this, and then provides enough and batch power.And this kind of design reduces the use amount of hardware in whole module, and then reduce the weight of module entirety.When wind spring is little, larger accommodation space can be reserved to earphone cord, reduce the volume of whole module further.
In order to adapt to wind spring to be put into groove to reduce the design of thickness, the application upper shell will be provided with a rotating shaft, and stretches in wind spring groove by rotating shaft through swivel, and one end of wind spring is fixed by flat recess and rotating shaft, and the other end and swivel are fixed.Such design makes wind spring can fix two ends with the shortest distance, need not be fixed on upper shell to a part of wind spring be smoothed out with the fingers direct puncture rotary body fixing with upper shell rotating shaft, decrease the transmission distance of the power of batching, and rotational force can be made more even.The spinning movement of swivel has had the restriction of rotating shaft also can not produce the situation of eccentric rotary, can more even by earphone cord from being wound.
One end of earphone cord will be connected with loud speaker, and the other end must frames connecting with headphone signal circuit.In the prior art, generally can carry out curling winding by the middle part of earphone cord, and tail end is still connected with head circuit by earphone cord, such mode need a flexible clamp piece block earphone cord a bit, thus the one end that earphone cord can not be made to be connected with head circuit when the power of batching is large is subject to excessive pulling force and solder joint is thrown off.But the material of such design flexibility fastener requires high, and in the process of assembling, to need between flexible clamp piece and solder joint the earphone cord of reserved one section of regular length, this section of earphone cord is greater than the circuit distance between flexible clamp piece and solder joint.Such design both wasted material, added the weight of whole module, and when the pulling force that earphone cord receives be greater than the card of flexible clamp piece and power or engagement piece loosen, all can not reach original effect, make the life-span of earphone have received impact.
So the application has abandoned such design when designing, the structure adopting pcb board to be combined with brush has been used as electric connection structure.
In scheme in the application, pcb board is fixed on the lower surface of lower house by screw; Brush is fixedly connected with one end of earphone cord, and contacts with pcb board, is electrically connected with head circuit by pcb board.So both ensure that the stability of power taking, turn improve the service life of earphone, and due to its compact conformation, do not need unnecessary wire rod to bear pulling force, which offers a saving the volume of unit design, be convenient for carrying use.
The design of the application by being arranged at the limit assembly between swivel and upper shell, restriction swivel and upper shell between when taking out line unidirectional rotation.It comprises some rotations projection and position-limited trough.Rotating protruding upper surface plan view shape is arc, and be arranged on surface that swivel contacts with upper shell, its upper surface is the inclined-plane that higher end is low, and the ascent direction on inclined-plane is swivel hand of rotation reverse when taking out line; Described position-limited trough is arranged on upper shell, shape and size and the rotation male cooperation of position-limited trough.
The upper surface of rotation projection is arranged to the low inclined-plane of higher end and mainly in rotary course, be realized unidirectional rotation in order to ensure.
Rotate protruding inclined-plane during rotation to arrive again from low to high and lowly to contact with upper casing, to the effect of upper casing vitality, above upper casing, have spring, spring force is provided.So when pulling, upper casing is at ceaselessly up-and-down movement.The line being wound into rotating shaft can pull out.When loosing one's grip, under being subject to the effect of the spring restoring force of the wind spring at a rotating body, rotating body clockwise rotates.Rotating projection is stuck in position-limited trough, rotates and stops.Now line can be fixed to certain length.The length being limited earphone cord pull-out by this mode can person easy to use pull as required, as move time in order to avoid sound-scope effect can line draw shorter, and when every day use, earplug can not be pulled out from cochlea to ensure that head rocks, can earphone cord pull-out longer.
And rotate end to end between two between projection and be arranged on swivel according to homocentric arc line type, shape, the arrangement of position-limited trough are protruding identical with rotation.If rotate projection can not ensure to arrange according to homocentric arc line type, so in rotary course, due to departing from of axle center, swivel appears in the jam effect that certain a period of time cannot realize single direction rotation, the optional point of the adjustment length of such earphone cord will be much less, earphone cord can only select regular length at some less attachment point, and also can affect the smooth degree of the rotation of swivel like this, affects the feel of bracing wire.
In the scheme of the application, if realize single direction rotation, so when reversing, ensure that rotating projection can easier enter in position-limited trough, one end that such rotation convexity is higher just can snap into the sidewall of position-limited trough, so rotate protruding oad in the scheme of the application to be less than position-limited trough.
And need to receive in short-term at earphone cord, existing design generally adopts the physical construction of outside pull one section then earphone cord the automatic recovery, this kind of reliability of structure is not high, pull is often needed repeatedly to realize, the application has abandoned this structure, is realized the automatic recovery of earphone cord by simple button operation.
The return button of the application is connected with upper shell, and depending on the upper-lower position that return button and upper shell are placed, user can press return button or upwards be lifted by return button.Because return button is rotationally connected by base and upper shell, base is provided with two grabs, the top of two bendings of grab contacts with the upper surface of swivel, and this upper surface is the surface that swivel contacts with upper shell.Such grab and base define a lever, according to lever principle, upper shell produces a relative motion away from swivel, and the rotation on swivel is protruding to depart from position-limited trough, position-limited trough disappears to the restriction of swivel, and swivel rotates and batches earphone cord under the restitution of wind spring.
Due in the technical scheme of the application, upper shell and swivel are bolted.
In order to make above-mentioned automatic winding scheme realize, augmenting and spring is set between bolt and upper shell.Spring can provide a downward power when pull earphone cord, facilitate position-limited trough and rotate after projection departs under the effect on inclined-plane and can resume contacts rapidly.And provide a upper shell can the activity space of upward movement by the length of spring, a free activity can be had for upper shell during take-up.
And by the effect of spring, in take-up process, if the length that take-up needs to user, only need unclamp the power for return button, by position-limited trough and the cooperation rotating projection, swivel can stop the rotation, and person easy to use adjusts take-up length.
The mode adopting brush and pcb board to coordinate due to the application is electrically connected, so how to ensure that the good contact of brush and pcb board just becomes an important problem, in prior art, the fixed form of brush has a variety of, as connected by groove inserted sheet, be bolted to connection, but the defect that aforesaid way has it intrinsic, the mode of grafting has with fixing dynamics less, be applicable to contact little, use when the direction of power does not change, and brush will be fixed on swivel by the application, the rotation of swivel is to the power bringing various direction between brush and swivel, and due to the restriction of thickness and intensity, on swivel, fluting is difficult to realize, institute is obviously improper by this way.And adopt be screwed also inapplicable, although the mode that screw is fixed be easy to most operation and cost is minimum, but due to the rotation of swivel, the rotational force of a transverse direction can be produced between brush and swivel, be easy to like this make screw loosening, affect fixed effect, use when being adapted at non-rotary body, improper in this application.
So the brush of the application is fixedly connected with swivel by hot molten column, hot molten column is fixedly connected with brush by hot melting way.Such mode can ensure the stability that brush and swivel are fixed.Further, owing to being difficult to the unitarity ensureing oad in brush manufacturing process.Adopt in this way, even if the size of profile is variant when brush manufactures, under the mobilization after hot molten column hot melt, hot molten column also can form a suitable fixed housing according to the oad of brush attachment point, provides good fixed effect.
In this application, the surface thickness that protruding vertex hill height is less than upper shell is rotated.Can ensure that the surface of upper shell can not produce projection like this, prevent the miscellaneous part that can not be suspended in the process of rotary wire-reeling or unwrapping wire in earphone.
And rotate the compressible stroke that protruding vertex hill height is also less than spring, the scheme of such guarantee the application can be implemented.
In the scheme of the application, otch runs through leading groove by the edge of swivel and to be split by wire casing wall and open a gap.That is, a breach running through wire casing axis is had in the wire casing of the application.Generally, earphone inner component all adopts Plastic Parts to make, and arranges such breach, can ensure that the wire casing of swivel has a radial shrinkage amount.
Above-mentionedly to mention, in the scheme of the application, because the diameter of the wind spring used is little, so adopt the wind spring material that yield tensile ratio is larger to make, so just have a problem, the elastic force of wind spring can not ensure evenly, can produce the situation of size inequality in its whole working process, and the winding power of such earphone cord on wire casing also can size inequality.
After earphone cord from being wound has been got well, if do not regulate this situation, earphone cord just has uneven stress and produce, after long-time like this, earphone cord, easily from internal break, affects the service life of earphone.And due to the problem of manufacturing process, the elastic force of wind spring is difficult to reach unified standard, when assembling, just needs operator to check the elastic force of wind spring in turn, extending working time like this, add productive costs.
Above-mentioned breach uses to solve this situation, when the winding power of earphone cord becomes later large or different wind spring elastic force differences, earphone cord will produce a convergent force to wire casing, when this convergent force, wire casing will inwardly shrink due to the existence of breach, so just the stress of earphone cord inside be displaced a part to wire casing.Because wire casing adopts plastics manufacture, this power can not produce large impact to the intensity of wire casing, but the internal stress of the copper cash of earphone cord inside is little, would not be broken by pulling force, this ensure that the service life of earphone cord.
Embodiment two
As shown in Figure 4,5, the present embodiment and the difference of embodiment one are to rotate the protruding surface being arranged at upper shell and contacting with swivel, and position-limited trough is arranged at the position with rotation male cooperation on swivel; The described upper surface plan view shape rotating projection is arc, shape and the rotation male cooperation of position-limited trough.
Rotating projection is arranged on swivel, so the maximum ga(u)ge of position-limited trough is the thickness of upper shell, in order to the volume of whole module is reduced, it is very thin that the thickness of upper shell can do, such maximum ga(u)ge rotating projection is just restricted, what such rotation was protruding will produce wearing and tearing when wind spring output torque is large, uses a period of time can lose efficacy later.And position-limited trough is arranged on swivel, the thickness of position-limited trough will increase relative to embodiment one, and its position-limiting action improves, and due to thickness increase, the time of the rate of wear and wearing and tearing can increase, and further increases the service life of module.
Obviously, those skilled in the art can carry out various change and modification to utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
