 本发明的最佳实施方式
下面结合附图和实施例对本发明作进一步的描述。
参考图1，本发明提供的一种线缆的伸缩结构，包括底板10以及安装到底板10的盒体20。底板10用于放置到水平面例如桌面等，以便伸缩结构的放置。盒体20具有至少一个圆形的安装腔201（见图2）。盒体20包括盒体本体21以及安装到盒体本体21的上盖22。盒体本体21和上盖22之间围合形成至少一个所述安装腔201。
本实施例的盒体20具有两个圆形的安装腔201，两个安装腔201呈对称设置。盒体20呈近似“8”字型。下面主要以一个安装腔201的结构进行详细说明。
参考图2，安装腔201内设有绕线支架30，绕线支架30的顶端和底端分别设有收紧件40和第一PCB（印制电路板）50。安装腔201内的底部设有连接轴202。第一PCB50、绕线支架30和收紧件40分别套设到连接轴202并可相对连接轴202转动，收紧件40的一端连接到绕线支架30，另一端连接到连接轴202。绕线支架30上绕设有线缆60，线缆60的第一端与第一PCB50电连接，线缆60的第二端从盒体20上伸出并位于盒体20之外，且具有接口61，线缆60为充电线或数据线，接口61用于与电子产品例如手机等连接，以实现给电子产品例如手机等充电或传输数据等。接口61例如为USB接口、TYP-C接口等等。盒体20的侧面具有供线缆60的第二端伸出的槽口23（见图1、图2）。当手动拉线缆60时，绕线支架30可在线缆60的作用下转动从而可实现线缆60的拉伸，此时收紧件40随着绕线支架30转动并发生形变而处于收紧状态。当收缩线缆60时，收紧件40在其形变恢复力的作用下带动绕线支架30回转以实现自动收缩线缆60，从而实现将线缆60收纳于安装腔201内。
安装腔201的底部设有第二PCB70，第二PCB70固定套设到连接轴202，且电连接有连接线80，连接线80的一端从盒体20上伸出并位于盒体80之外，且具有连接接口（图上未示出），连接接口用于与其他电子设备连接以实现通过现线缆60给电子产品例如手机等充电或传输数据。第二PCB70的靠近绕线支架30的一面上设有连接件71，第一PCB50的远离绕线支架30的一面设有弹片连接器51，连接件71与弹片连接器51接触导通，从而可实现第一PCB50和第二PCB70之间的电连接。
本实施例中，连接件71由若干沿一径向间隔排列的环状的铜箔组成，若干环状的铜箔都环设在连接轴202的外周，弹片连接器51为两个。
底板10上在位于盒体20的一侧安装有框架11。框架11的底端具有至少一个滑动腔12，结合图5所示，滑动腔12与安装腔201对应。滑动腔12与对应的安装腔201呈垂直设置。本实施例的滑动腔12也为两个。
滑动腔12内滑动设置有锁紧部件90，锁紧部件90的第一端穿过盒体20并伸入对应的安装腔201内，且锁紧部件90的第一端的靠近绕线支架30的一侧设有卡件91，锁紧部件90的第二端连接到解锁部件100。盒体20的侧面具有供锁紧部件90的第一端穿过的槽位24。
绕线支架30的底端具有一环槽31，结合图4所示，环槽31的内壁间隔设置有多个卡块311，卡块311具有相对的第一端311a和第二端。卡块311的第一端311a的延伸方向与绕线支架30回转时的方向相同，本实施例的绕线支架30在收缩线缆60时沿逆时针方向回转，绕线支架30在拉伸线缆60时沿顺时针方向转动，因而卡块311的第一端311a的延伸方向为逆时针方向。卡块311的第二端与环槽31的内壁之间通过圆弧311b过渡，卡块311的顶面为弧面311c，弧面311c与圆弧311b平滑过渡。卡件91用于卡设到其中一个卡块311的第一端311a从而可实现在线缆60被拉伸后锁紧绕线支架30以防绕线支架30在收紧件40的形变恢复力带动下回转。在实际拉伸线缆60时，绕线支架30在线缆60的作用下沿顺时针方向转动，随着绕线支架30的转动，位于后一个卡块311的圆弧311b、弧面311c、第一端311a会依次与卡件91接触，当停止拉伸线缆60时，例如卡件91位于前后两个卡块311之间时，卡件91会卡设到前一个卡块311的第一端311a从而实现锁紧绕线支架30，此时绕线支架30停止转动。通过卡件91卡设到卡块311的第一端311a可实现定位线缆60的拉伸距离。卡块311的个数可根据实际情况进行设定。
结合图1所述，解锁部件100的顶端转动安装到一支撑轴110。具体的，解锁部件100的顶端具有一贯穿解锁部件100两侧的通孔102，支撑轴110穿设在通孔102中，解锁部件100通过通孔102可在支撑轴110上转动。支撑轴110的两端分别安装到两个支撑柱120，两个支撑柱120分别安装到底板10并位于框架11的两侧，支撑柱120可实现对支撑轴110提供支撑。本实施例的盒体20包括两个安装腔201，相应地，锁紧部件90和解锁部件100也两个，两个解锁部件100的顶端转动到同一支撑轴110。
解锁部件100的远离锁紧部件90的一面具有伸出的按动部101，当线缆60被拉伸后并朝靠近底板10的方向手动按住按动部101时，解锁部件100可相对支撑轴110朝靠近锁紧部件90的方向转动并可推动锁紧部件90朝靠近对应的安装腔201的方向移动，使得锁紧部件90的卡件91脱离对应的卡块311的第一端311a并位于环槽31内从而可实现解锁绕线支架30，从而绕线支架30可在收紧件40的形变恢复力带动下回转以实现自动收缩线缆60。
本实施例中，锁紧部件90的第二端通过第一弹性件130连接到解锁部件100的底端。锁紧部件90的顶端具有沿其轴向延伸的安装位92，滑动腔12内的顶部设有伸入安装位的伸出部111（见图5），第一弹性件130的一端连接到解锁部件100的底端，另一端穿过锁紧部件90的第二端并伸入安装位92内，且连接到伸出部111。通过设置的第一弹性件130，当朝靠近底板10的方向手动按住按动部101时，第一弹性件130被压缩，当放开按动部101时，第一弹性件130回弹并带动解锁部件100、锁紧部件90自动复位，此时锁紧部件90的卡件91又会重新卡设到绕线支架30的其中一个卡块311的第一端311a，从而实现重新锁紧绕线支架30。
框架11的底端具有至少一个收容腔13，结合图5所示，收容腔13位于滑动腔12的一侧并与滑动腔12平行。本实施例的收容腔13也为两个，两个收容腔13位于两个滑动腔12之间。
收容腔13内设有第二弹性件140，第二弹性件140的一端连接到收容腔13的一端端壁，另一端穿过收容腔13的另一端端壁并与解锁部件100的底端连接。设置的第二弹性件140，可提高带动解锁部件100自动复位的动力，以实现解锁部件100的快速复位，从而实现锁紧部件90的快速复位。
本发明在实际使用时，以右侧的安装腔201的结构为例，当需使用线缆60时，手动拉线缆60，绕线支架30在线缆60的作用下相对连接轴202沿顺时针方向转动从而实现拉伸线缆60，此时收紧件40随着绕线支架30转动并发生形变而处于收紧状态，当线缆60拉伸到合适的距离后，放开线缆60，此时锁紧部件90的卡件91会卡设到绕线支架30的其中一个卡块311的第一端311a从而实现锁紧绕线支架30，从而阻止了绕线支架30在收紧件40的形变恢复力带动下回转，此时线缆60就定位在该距离了，此时即可使用线缆60。若要再拉伸线缆60，则继续手动拉线缆60即可直到线缆60拉伸到满意的距离。当线缆60使用完毕后，朝底板10的方向手动按住解锁部件100的按动部101，解锁部件100会相对支撑轴110朝靠近锁紧部件90的方向转动并推动锁紧部件90朝靠近对应的安装腔201的方向移动，此时锁紧部件90的卡件91会脱离对应的卡块311的第一端311a并位于绕线支架30的环槽31内，从而实现解锁绕线支架30，此时绕线支架30在收紧件40的形变恢复力带动下回转即逆时针方向转动，从而实现自动收缩线缆60，使得线缆60重新绕设到绕线支架30上，从而实现将线缆60收纳于安装腔201内。可以理解地，在收缩线缆60的过程中，可随时停止收缩线缆60，具体的，在收缩线缆60时放开按动部101，此时解锁部件100、锁紧部件90会在第一弹性件130、第二弹性件140的回弹作用下自动复位，锁紧部件90的卡件91会卡设到绕线支架30的其中一个卡块311的第一端311a，从而实现锁紧绕线支架30，此时绕线支架30不会在收紧件40的形变恢复力带动下回转，即实现停止收缩线缆60，使用灵活。
参考图2至图4，本实施例中，绕线支架30具有供套设到连接轴202的轴向通孔34，绕线支架30的外周具有绕线槽35，绕线槽35的底部具有与轴向通孔34连通的通道351，线缆60绕设到绕线槽35，线缆60的第一端穿过通道351、轴向通孔34并与第一PCB50电连接。
绕线支架30的顶端和底端分别具有第一腔32、第二腔33，收紧件40设置在第一腔32内，环槽31环设在第二腔33的外周，第一PCB50设置在第二腔33内。
优选地，收紧件40为一发条圈，发条圈的外端连接到第一腔32底部的支柱321，发条圈的内端连接到连接轴202的远离安装腔201底部的一端。
参考图2、图6至图8，绕线支架30的顶端在对应第一腔32的位置设有发条盖36，发条盖36覆盖收紧件40，且发条盖36的顶端中心位置处形成有凸出的配合部361，配合部361位于盒体20（即上盖22）顶端的安装孔203内并具有齿位361。发条盖36的外周设有阻挡件37，阻挡件37形成在绕线支架30的顶端，阻挡件37用于对发条盖36进行定位。
盒体20的顶端在对应安装孔203的位置设有安装框25，安装框25内安装有阻尼器150，阻尼器150的齿件153与发条盖36的齿位362配合，用于在绕线支架30在收紧件40的形变恢复力带动下回转时减慢绕线支架30的转动速度，从而实现减慢自动收缩线缆60的速度，可防止收缩线缆60时产生异响或者伤害到人体。
具体的，阻尼器150包括圆形的阻尼器本体151、转动安装到阻尼器本体151一面的转轴152以及固定套设到转轴152的远离阻尼器本体151一端的所述齿件153。阻尼器本体151的侧面形成有两个相对的安装部154，两个安装部154通过紧固件例如螺钉等安装到安装框25两端的安装位251内。阻尼器本体151和转轴152均位于安装框25内。
本发明还提供一种应用上述的线缆的伸缩结构的充电座，通过线缆60的接口61可实现给电子产品例如手机等充电用。盒体20的顶端设有安装盒，安装盒内设有隔磁片以及设置在隔磁片上的无线充电发射组件，无线充电发射组件与安装腔底部的第二PCB70电连接。通过无线充电发射组件可实现对放置在安装盒顶端的电子产品例如手机等进行无线充电。无线充电发射组件为单层或双层的发射线圈。因而本发明的充电座可实现对电子产品例如手机等有线充电或无线充电，具有多种功能。本实施例可同时实现给两个电子产品进行有线充电。
 本发明的实施方式
以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，如对各个实施例中的不同特征进行组合等，这些都属于本发明的保护范围。
