Description

一种智能升降桌 技术领域
本发明涉及电动家具领域，特别是一种智能升降桌。
背景技术
传统的桌子为固定式结构，桌子的桌面呈平面结构，不仅不能进行倾斜，也不能升降，因此存在两个弊端，一方面人们在使用过程中，会因为伏案时间过长而感到疲劳，尤其对于使用更不方便，另一方面由于一些家庭或办公场所中的桌子不是特定给一个人使用，而每个人的身高都是不一样的，再者儿童的身高会随着年龄的增大而不断增长，所以此种桌子就无法满足不同状态下的高度需求。
而升降桌的诞生解决了上述问题，升降桌一般分为电动的和手动的，手动的升降桌通过手动操作机械传动结构达到桌子升降调节或桌面调节的效果。虽然实现了灵活调节的目的，但是操作麻烦、费力。
自动升降桌一般是以电为动力来源，通过电动机控制机械装置来调节升降桌的高低，也可以通过压缩机控制气压棒或液压棒来调节升降桌的高度。优点是用电量很小、样式稳固美观、可升降范围大。但是，此类自动升降桌仍然无法满足日益多元化的使用需求。例如，对于桌面板的调节控制：桌面板的平移或翻转。这些功能都亟待开发，而且需要同步满足新颖的控制设计，才能够符合大众的预期要求。
发明内容
本发明目的是：提供一种智能升降桌，解决了在椅子不动的情况下可以将桌面板调节到自己和舒适的位置的问题，特别是可以实现桌面角度翻转的问题。
本发明的技术方案是：一种智能升降桌，包括作为结构承载体的支撑框。支撑框作为承载的基础，同时也作为了桌面的基础框架而存在。具体的，支撑框为型材拼接而成的一个具有桌面长度方向及桌面宽度方向的框架。在支撑框的外部一般安装外壳，可以确保桌面板的外形美观。
整个升降桌桌面结构是安装于升降桌腿上的，升降桌腿为集成模块，其包括了可叠套伸缩的支撑腿，支撑腿的下部为底座，支撑腿的上部为连接端。连接端通过紧固件连接至支撑框上的连接部，这样可以实现两个部分的安装固定。
因此，对应的在桌面壳体上开设有对应连接部的窗口，升降桌腿的连接端从窗口进入桌面壳体内并连接至支撑框上。为了确保结构完整及外形美观，在窗口上设有盖板。盖板包括相互对缝拼接的：第一板块和第二板块，且第一板块与第二板块上均开设有与连接端外形匹配的缺口。通过缺口与连接端的外表面接触匹配，使得盖板与连接端无间隙装配。
除了基础框架，升降桌桌面结构还包括电动控制的调组调节组件，即：平移组件和翻转组件。平移组件及翻转组件均布置在支撑框中，具体的，翻转组件布置在平移组件上，而桌面板则布置在翻转组件上。因此，运动的原理是：平移组件能够带着翻转组件及翻转组件上的桌面板在平面内进行移动，而翻转组件则为桌面板提供了倾仰翻转的动力。
平移组件为直线伸缩结构，平移组件设置有两组；两组平移组件平行设置，因此具有统一的伸缩方向；两组平行组件同步传动，因此具有统一的运行状态。具体的，平移组件包括起导向效果的：第一部件、第二部件。第一部件与第二部件均为空心方管，第二部件叠套于第一部件内。因此，第二部件可以沿着第一部件滑动伸缩，而第二部件相对于第一部件伸出的端头即为平移端。固，第二部件的滑动伸缩方向即是可调节的平移方向。
第一部件和第二部件之间通过丝杆结构来解决传动问题，具体的，在第一部件内设置一根第一丝杆，在第二部件的端部安装第一螺套，第一螺套装配在第一丝杆上，当第一丝杆正向或反向转动时，第二部件就会随着第一螺套产生相对于第一部件的滑动。
第一丝杆是由平移传动部来驱动的，在第一丝杆的端部配合一个齿轮箱，齿轮箱同时配合在一根垂直于第一丝杆的传动杆上，该传动杆同时驱动两组平移组件，而传动杆则由第一电机及齿轮箱来驱动。
翻转组件为一个滑块连杆机构传动升降结构，翻转组件也设置有两组，每一个翻转组件配套一个平移组件。两组翻转组件也需要满足同步控制的效果，因此两组翻转组件也具有同步的运动状态。具体的，翻转组件包括：第二丝杆、翻转传动部、支臂。第二丝杆布置于第二部件上，第二丝杆与第一丝杆均沿着桌面宽度方向设置。在第二部件上套装第二螺套，第二螺套上铰接至支臂的一端，支臂的另一端铰接至桌面板上的连接部。因此，第二丝杆、第二螺套、支臂就组成了一个滑块连杆结构，而支臂的倾仰方向与桌面板的倾仰方向是相同的。为了满足桌面板可以稳定的翻转，桌面板的端部是通过转动部铰接在平移端上的。
第二丝杆的转动则是由第二电机及齿轮箱来驱动的，两组翻转组件的运行状态同步，因此两个第二电机的控制是同步的。
与平移端同步位移的第二丝杆、驱动第二丝杆转动的翻转传动部、随第二丝杆上螺套移动的支臂；
桌面板的底面上包括一个转动部和一个连接部，转动部上包括一个座位桌面板翻转支点的转轴，第二丝杆与转轴在空间内垂直。因此，桌面板以转动部为支点，随着支臂的上倾，桌面板不断抬起。
基于上述的动力及传动结构，本方案中还需要具备控制上述动力源的控制系统。具体到产品结构上，包括设置在控制盒内的：检测芯片、控制芯片、六轴传感器。
控制芯片是用于系统控制上述动力原件的，具体的包括控制各动力件的供电情况。一般，在产品结构上表现为外部的一个手控器，该手控器布置与桌面板的边缘，便于手部操作。可以通过按键或者摇杆控制，对应升降桌的6个运动方向。具体的，第一电机具备控制桌面板移动和后退两个转动方向；第二电机具备控制桌面板仰起和翻倒两个转动方向；第三电机具备控制桌面升起和降下两个转动方向。
对应到手控器上也相应的存在6个控制“手势”，因此本方案中采用的是摇杆旋钮手控器。摇杆旋钮手控器包括设置在其壳体上的：圆筒状的转动部、以同轴设置于转动部内的摇杆。摇杆旋钮手控器通过其壳体安装固定在桌面结构上，通过操作摇杆及转动部来控制升降桌变形。
具体的，摇杆的运动方向包括径向上的四个摆动方向及轴向上的一个伸缩方向，转动部的运动方向包括轴向的回转。因此，在摇杆旋钮手控器的壳体内包括：对应摇杆五个运动方向收集摇杆运动状态的位移信号触发点、对应转动部回转运动状态收集转动部转动状态的转动信号触发点。
摇杆包括：沿前、后、上、下四个方向径向摆动的运动状态、及沿轴向方向按压回弹的运动状态。具体的分为：摇杆沿上、下方向径向摆动的运动状态对应控制第三电机驱动支撑腿伸出、缩回；摇杆沿前、后方向径向摆动的运动状态对应控制第一电机驱动平移端缩回、伸出。
转动部包括向上、向下回转的运动状态，转动部向上、向下回转的运动状态对应控制第二电机驱动桌面板仰起、倾倒。
在该控制方式下，手控器操作升降桌发生形变。因此，在六轴控制时需要确保桌面的移动稳定，避免抖动。具体的，六轴传感器可以检测第一电机、第二电机、第三电机， 三根输出轴共六个转动方向的角加速度。当所测电机输出轴沿一回转方向转动的角加速度大于0.5～0.7时，控制芯片控制该电机输出轴停止并沿相反回转方向转动0～5cm。例如：但第一电机产生桌面板前移的转动时，若此时第一电机的转动角加速度大于0.7，桌面板的移动会产生抖动，运动平衡收到影响。因此，六轴传感器在检测到其角加速度过大后，会给控制芯片发出检测信号，控制芯片则对应控制第一电机制动，并发送反向转动的控制指令，控制第一电机反向转动0～5cm，桌面板确保运动稳定。
对应操作控制，各电机需要在收到阻止力时产生制动或翻转，即为了避免桌面板在运行过程中碰撞或夹手而过载，各电机的控制需要满足自动反馈的效果。因此，在各电机上连接一个检测芯片。检测芯片可以检测各电机工作时的工作电流，当检测芯片检测到当前电机的工作电流大于正常工作电流时，检测芯片发送信号至控制芯片，控制芯片控制当前电机反向转动。
本方案的解决的另一个问题是，避免儿童误操作，尤其是对于手控器的操作。因此，在手控器上设置了童锁开关，对应在控制芯片上则具备一个童锁单元。因此，该童锁单元能够通过对控制信号的通断控制来达到控制手控器的正常操作的目的。
本发明的优点是：
1.本结构可以实现升降桌桌面板的水平移动和角度倾仰，采用电动控制，能够满足多元的使用需求。
2.以电机及丝杆传动作为主要的供能，可以确保桌面板运动的稳定性。同时，本结构的传动响应迅速，可以达到快速调节的目的。
3.整体结构稳定性好，噪音小，操作使用感好。而且，结构布置合理，易于维护和修理。

具体实施方式
本发明的较佳实施例1：
一种智能升降桌，包括桌板、桌面结构、升降桌腿。
桌面结构包括支撑框1，支撑框1作为承载的基础，同时也作为了桌面的基础框架而存在。具体的，支撑框1为型材拼接而成的一个具有桌面长度方向及桌面宽度方向的框架。在支撑框1的外部一般安装外壳，可以确保桌面板的外形美观。
整个升降桌桌面结构是安装于升降桌腿13上的，升降桌腿13为集成模块，其包括了可叠套伸缩的支撑腿，支撑腿的下部为底座，支撑腿的上部为连接端14。连接端14通过紧固件连接至支撑框1上，这样可以实现两个部分的安装固定。
因此，支撑框1上设有连接部来对接连接端14，对应的在桌面壳体上开设有对应连接部的窗口17，升降桌腿的连接端14从窗口进入桌面壳体内并连接至支撑框1上。为了确保结构完整及外形美观，在窗口17上设有盖板。盖板包括相互对缝拼接的：第一板块15和第二板块16，且第一板块15与第二板块16上均开设有与连接端14外形匹配的缺口。通过缺口与连接端的外表面接触匹配，使得盖板与连接端无间隙装配。
桌面板2安装于桌面结构上，通过平移组件及翻转组件使得桌面板2具备了平面内平移及倾仰翻转的功能。
平移组件安装于支撑框1中，翻转组件布置在平移组件上，而桌面板则布置在翻转组件上。
平移组件包括起导向效果的：第一部件3、第二部件4。第一部件3与第二部件4均为空心方管，第二部件4叠套于第一部件3内。因此，第二部件4可以沿着第一部件3在桌面宽度方向上滑动伸缩。
在第一部件3内设置一根第一丝杆5，在第二部件4的端部安装第一螺套6，第一螺套6装配在第一丝杆5上，当第一丝杆5正向或反向转动时，第二部件4就会随着第 一螺套6产生相对于第一部件3的滑动。
在第一丝杆5的端部配合一个齿轮箱，齿轮箱同时配合在一根垂直于第一丝杆5的传动杆7上，该传动杆7同时驱动两组平移组件，而传动杆7则由第一电机8及齿轮箱来驱动。
翻转组件包括：第二丝杆9、翻转传动部、支臂10。第二丝杆9布置于第二部件4上，第二丝杆9与第一丝杆5均沿着桌面宽度方向设置，第二丝杆9由第二电机12及齿轮箱来驱动。在第二部件4上套装第二螺套11，第二螺套11上铰接至支臂10的一端，支臂10的另一端铰接至桌面板2上的连接部22。
桌面板2以转动部21为支点，转动部21上包括一个转轴，第二丝杆9与转轴在空间内垂直。因此，桌面板2以转动部21为支点，随着支臂10的上倾，桌面板2不断抬起。
本发明的较佳实施例2：
一般本结构中会有一个控制盒，然后操作时通过一个手控器连接到一个控制盒上，这个控制盒连接着5个电机，其中两个电机控制桌面升降，两个电机控制翻转(这两个电机同步运动)，一个电机控制平移。一个手控器可以控制这三个动作，这三个动作相互不干涉，随意操作。
对应到手控器18上也相应的存在6个控制“手势”，因此本方案中采用的是摇杆旋钮手控器。摇杆旋钮手控器包括设置在其壳体上的：圆筒状的转动部141、以同轴设置于转动部内的摇杆142。摇杆旋钮手控器通过其壳体安装固定在桌面结构上，通过操作摇杆及转动部来控制升降桌变形。
具体的，摇杆142的运动方向包括径向上的四个摆动方向及轴向上的一个伸缩方向，转动部141的运动方向包括轴向的回转。因此，在摇杆旋钮手控器的壳体内包括：对应摇杆五个运动方向收集摇杆运动状态的位移信号触发点、对应转动部回转运动状态收集转动部转动状态的转动信号触发点。
摇杆142包括：沿前、后、上、下四个方向径向摆动的运动状态、及沿轴向方向按压回弹的运动状态。具体的分为：摇杆142沿上、下方向径向摆动的运动状态对应控制第三电机驱动支撑腿伸出、缩回；摇杆142沿前、后方向径向摆动的运动状态对应控制第一电机8驱动平移端缩回、伸出。
转动部141包括向上、向下回转的运动状态，转动部141向上、向下回转的运动状 态对应控制第二电机12驱动桌面板仰起、倾倒。
升降桌具备的三个运动方式：
升降：在支撑腿上布置了第三电机，第三电机可以驱动升降腿产生竖直方向的伸缩。升降腿的设置方式包括多种，目前大多数升降桌腿均可作为本方案的支撑腿，因此升降桌腿并不在本方案的保护范围。
翻转：手控器通过控制盒控制两个第二电机12同步运动，这两个第二电机12分别通过一个小齿轮箱带动各自对应的第二丝杆9转动，每个第二丝杆9上用一个第二螺套11配合，第二丝杆9转动时第二螺套(螺套是不转动的)会在第二丝杆上运动，两个第二螺套会分别带动对应的支臂10将桌板支撑起来，从而实现翻转。
平移：一个第一电机8也通过一个小齿轮箱带动一根传动杆7转动，传动杆7了两端分别通过一个小齿轮箱带动对应的第一丝杆5转动，每个第一丝杆5上分别有一个第一螺套6，当第一丝杆5转动的时候第一丝杆5上的螺套会发生移动，每个第一螺套会分别带动对应的第二部件4移动，第二部件4和桌面板2相连，这样就实现了桌面板2的平移。
翻转组件和平移组件是相互独立的，这样就实现了平移和翻转两个功能相互不干扰了。
升降桌的三个单元的操作是基于对各自电动原件的操作控制，升降桌包括平移机构的第一电机、翻转机构的第二电机、升降桌腿的第三电机，三个电机具有6个运动方向。具体的，第一电机具备控制桌面板移动和后退两个转动方向；第二电机具备控制桌面板仰起和翻倒两个转动方向；第三电机具备控制桌面升起和降下两个转动方向。
控制盒内设置的六轴传感器用来检测第一电机、第二电机、第三电机，三根输出轴共六个转动方向的角加速度。当所测电机输出轴沿一回转方向转动的角加速度大于0.5～0.7时，控制芯片控制该电机输出轴停止并沿相反回转方向转动0～5cm。
除此之外，升降桌还具备了过载防夹的控制系统，即在各电机上连接一个检测芯片。检测芯片可以检测各电机工作时的工作电流，当检测芯片检测到当前电机的工作电流大于正常工作电流时，检测芯片发送信号至控制芯片，控制芯片控制当前电机停止或反向转动。
对应控制芯片，在桌面板的一侧边缘上设置了手控器，本实施例中手控器18为摇杆手控器，摇杆具备前后上下四个摆动方向控制，对应平移机构和升降桌腿的运动状态， 而摇杆的轴向转动控制则对应翻转机构的运动状态。在手控器18上还布置了童锁，将童锁锁止后，手控器18就无法进行任何操作，只有解开童锁后手控器18才能继续操作控制。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明的所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
