本发明的有益效果：
本发明公开的电动升降桌，通过升降立柱来驱动桌板做升降运动，以调整桌板在竖直方向的位置，满足用户的使用需求，为了保证桌板本体的结构强度，升降立柱不能直接安装在桌板本体上，需要在桌板本体上设置用于连接升降立柱的支撑框架来保证桌板本体的强度，避免桌板本体断裂或凹陷，在桌板本体内部设有用于安装支撑框架的空腔，使得支撑框架的至少部分可以被隐藏于空腔，提高升降桌的外观，降低了桌板本体的重量，同时还可以缩小桌板本体在安装了支撑框架后的整体厚度，桌板本体的下表面能够对支撑框架的至少部分进行遮蔽，使得支撑框架不会完全显露于桌板本体的下表面，提高升降桌外观的同时还增强了对灰尘等杂质的阻挡能力，此外还可以使升降立柱与支撑框架的连接部分结构隐藏在桌板本体内，避免用户误触而受到伤害，驱动电机则设置在升降立柱上，桌板本体不需要将驱动电机容纳在空腔内而增加桌板本体厚度；电动升降桌在包装时，支撑框架收容于空腔内，可以节省支撑框架的打包成本，也不会增加桌板本体的打包成本，桌板本体的下表面设有对应支撑框架的第一装配口，方便支撑框架在桌板本体上的拆装以及升降立柱与支撑框架的 拆装，另外用户在使用过程中其腿部也不容易接触到支撑框架部分而产生磕碰，以提高用户使用体验。
进一步的，所述电动升降桌还包括控制器，所述控制器在所述第一装配口处与所述支撑框架连接；或者，电动升降桌还包括控制器，所述桌板本体的下表面设置第二装配口，所述控制器在所述第二装配口处与所述支撑框架连接。控制器用于向升降立柱输入控制信号，来控制升降立柱上升、下降，控制器安装在支撑框架上，以使得控制器至少部分能够容纳于空腔内，以缩减整个桌板部分的厚度。
进一步的，所述电动升降桌还包括手控器，所述桌板本体的上表面、侧面和下表面其中之一设置第三装配口，所述手控器嵌入式安装于所述第三装配口。手控器能够方便用户对升降立柱进行控制，以选择桌板本体的高度位置，手控器镶嵌在桌板本体上，方便用户操作，且不会占据额外空间。
进一步的，所述电动升降桌包括两个升降立柱，所述桌板本体上对应所述两个升降立柱设有两个支撑框架和两个第一装配口。通过两个升降立柱来支撑、驱动桌板本体，能使桌板本体在升降过程中保持平稳，在桌板本体上设置多个支撑框架来与升降立柱进行配合，两个支撑框架之间存在间距，虽然在桌板本体内部仅设置一块能够与所有的升降立柱配合的支撑框架也能实现升降立柱的装配，但会增加整个桌板本体部分的重量和支撑框架的安装难度。
进一步的，所述控制器通过电线分别连接两个升降立柱，以控制所述两个升降立柱同时进行升降运动，所述电线布置于所述空腔内。电线能够传递信号，以向两个升降立柱同时发出上升、下降的控制指令，电线布置在空腔从而可以隐藏与桌板本体内，避免电线显露于外侧而影响升降桌外观，同时也防止用户误触电线，具有更好地安全性能。
进一步的，所述桌板本体上安装有防护盖板，所述防护盖板覆盖所述控制器。防护盖板能够遮挡控制器，减少灰尘等杂质进入到空腔内，防护盖板还可以起到对控制器的支撑作用，当控制器与支撑框架的配合出现松动时，防护盖 板能支撑控制器使其保持在空腔内，此外防护盖板还能防止用户误触控制器，避免出现触电事故。
进一步的，所述控制器和所述支撑框架其中之一设有卡槽，另一个设有滑块，所述控制器通过卡槽与滑块的配合插装在所述支撑框架上；或者，所述控制器通过螺钉固定在所述支撑框架上；或者，所述控制器粘连在所述支撑框架上。控制器与支撑框架之间为可拆连接结构，以方便对升降桌进行维护，通过卡槽与滑块配合的方式，控制器的拆装方式简单，方便用户操作；通过螺钉固定的方式，控制器在支撑框架的连接结构较为牢固，二者之间不易分离；通过粘贴的方式对控制器进行固定，安装时只需要将控制器对准第二装配口塞入到空腔内即可。
进一步的，所述手控器与所述控制器通过电线连接，所述电线布置在所述空腔内。手控器与升降立柱连接的电线布置在走线腔内，不会显露于桌板本体外，从而进一步提升升降桌的外观。
进一步的，所述两个支撑框架之间通过支撑架连接。支撑框架可以支撑桌板本体以增强桌板本体的强度，由于桌板本体内部设置了空腔导致桌板本体的强度下降，两个支撑框架之间的桌板本体部分缺少支撑框架的支撑，强度不如安装了支撑框架的部分，通过布置支撑架可以进一步增强支撑框架的强度。
进一步的，所述控制器安装在所述支撑框架上，所述支撑框架上设有固线槽，所述电线卡装于所述固线槽内。固线槽对电线具有限位作用，以方便电线的布置，此外，固线槽能使得电线直接穿过支撑框架，电线在连接升降立柱时，不需要在竖直方向绕过支撑框架的边缘位置而进入或伸出支撑框架，避免桌板本体的厚度因电线的布置而增加。
进一步的，所述桌板本体包括面板、自所述面板周沿向下延伸形成的挡边和安装在所述挡边下端的挡板，所述第一装配口设于所述挡板上。桌板本体内部中空，以形成用于安装并容纳支撑框架的空腔，桌板本体表面的液体可以沿着挡边滴落，避免液体进入到桌板本体内部空间而产生霉变或加快金属器件的 生锈速度，挡板可以遮挡面板下方的敞开部分，对灰尘、水汽等具有较好的阻挡效果，在装配过程中可以先将支撑框架装配到空腔内后再安装挡板，以方便桌板本体的装配。
进一步的，所述空腔内设有用于固定所述支撑框架的横梁，所述横梁与所述挡板和所述面板中的至少一个黏连。横梁用于将支撑框架固定在空腔内，同时横梁还具有一定的支撑性能，提高桌板本体的物理强度。
进一步的，所述空腔内还设有支撑于所述面板和所述挡板之间的支撑件。支撑件与面板和/或挡板相抵或相连，以方便挡板的安装，同时支撑件也得到了限位，并加固了桌板本体的结构，提高桌板本体的抗弯曲性能。
进一步的，所述支撑件为蜂窝件；或者，所述支撑件为发泡层；或者，所述支撑件为加强筋。蜂窝件具有较高的承载性能，能够增强桌板本体的强度，且蜂窝件的重量轻，内部具有多个孔洞，对震动具有较好的吸收效果；发泡层由发泡材料制成，发泡材料成本低、重量轻，发泡材料形成的支撑件，其本身不易弯曲，设置于桌板本体内以加强桌板本体的抗弯曲性能，发泡材料为一种填充材料，可以先将桌板本体完成组装后再填入发泡材料，形成黏连在挡板和面板上的发泡层，提高挡板的安装强度；加强筋则具有极强的抗弯曲性能，可以最大程度提高桌板本体的物理强度。
进一步的，所述驱动电机设置于所述升降立柱内部；或者，所述驱动电机安装在所述支撑框架上并与推杆传动连接。推杆活动所需的动力由驱动电机进行提供，驱动电机设置于升降立柱的内部，不会影响到桌板本体结构，若驱动电机装配于支撑框架上，通过第一装配口可以方便驱动电机的拆装，同时不会增加桌板的厚度。
进一步的，所述升降立柱设有两个，两个升降立柱之间设有装配在所述支撑框架上用于传递动力的传动部件，所述传动部件用于传递所述驱动电机的动力以同时驱动两个升降立柱。通过单个驱动电机来同时驱动两个升降立柱的升降运动，可以节省一个驱动电机的成本，通过设置传动部件可以将驱动电机的 动力传送至两个升降立柱上，以同时控制两个升降立柱，传动部件布置在支撑框架上，第一装配口可以方便传动部件、驱动电机和支撑框架的拆装。
本发明的这些特点和优点将会在下面的具体实施方式、附图中详细的揭露。

参照图1至图4，本发明实施例公开了电动升降桌，包括桌板和升降立柱 200，升降立柱200包括推杆和驱动推杆伸缩的驱动电机，桌板包括桌板本体100和支撑框架300，桌板本体100的上表面和下表面之间设有空腔400，支撑框架300嵌装于空腔400，桌板本体100的下表面设置第一装配口410，升降立柱200在第一装配口410处与支撑框架300连接，支撑框架300至少部分被桌板本体100的下表面遮蔽。升降立柱的结构可以参考现有的电动升降桌内的升降立柱，本申请中对具体结构不做展开。
本发明公开的电动升降桌，通过升降立柱200来驱动桌板做升降运动，以调整桌板在竖直方向的位置，满足用户的使用需求，为了保证桌板本体100的结构强度，升降立柱200不能直接安装在桌板本体100上，需要在桌板本体100上设置用于连接升降立柱200的支撑框架300来保证桌板本体100的强度，避免桌板本体100断裂或凹陷，在桌板本体100内部设有用于安装支撑框架300的空腔400，使得支撑框架300的完全被隐藏于桌板本体100内部(也可以是至少部分隐藏)，提高升降桌的外观，降低了桌板本体100的重量，同时还可以缩小桌板本体100在安装了支撑框架300后的整体厚度，从升降桌的侧部无法观察支撑框架300，桌板本体100的下表面能够对支撑框架300的至少部分进行遮蔽，使得支撑框架300不会完全显露于桌板本体100的下表面，提高升降桌外观的同时还增强了对灰尘等杂质的阻挡能力，此外还可以使升降立柱200与支撑框架300的连接部分结构隐藏在桌板本体100内，避免用户误触而受到伤害，驱动电机则设置在升降立柱200上，桌板本体100不需要将驱动电机容纳在空腔400内而增加桌板本体100厚度；电动升降桌在包装时，支撑框架300收容于空腔400内，可以节省支撑框架300的打包成本，也不会增加桌板本体100的打包成本，桌板本体100的下表面设有对应支撑框架300的第一装配口410，方便支撑框架300在桌板本体100上的拆装以及升降立柱200与支撑框架300的拆装，另外用户在使用过程中其腿部也不容易接触到支撑框架300部分而产生磕碰，以提高用户使用体验。
升降立柱200端部固定设置有安装板201，以通过安装板201与支撑框架300的螺钉配合装配至支撑框架300上。
其中，桌板本体100上的空腔400的成型方式有多种，作为优选的，桌板本体100包括面板110和设置于面板110下方的挡板120组成，二者之间形成空腔400，通过这样的方式桌板成型较为方便，可以先将面板110和挡板120成型后，再将支撑框架300安装在面板110上的合适位置后，最后将挡板120与面板110进行装配，第一装配口410则设置在挡板120上。
面板110的周沿向下延伸形成的挡边130，挡板120与挡边130连接，面板110和挡板120形成内部中空的桌板本体100，以使支撑框架300容纳在内。挡边130自面板110向下延伸，桌板本体100表面的液体可以沿着挡边130滴落，避免液体进入到桌板本体100内部空间而产生霉变或加快金属器件的生锈速度，挡板120可以遮挡面板110下方的敞开部分，仅设置了方便支撑框架300拆分的开口，对灰尘、水汽等具有较好的阻挡效果。
此外，桌板本体也可以为一整块的板材，在板材底部形成具有开口的空腔；或者，桌板本体采用木质材料制成，木头材质的桌板本体重量较轻且容易加工，使用某种工艺将桌板本体内部挖空形成中空板体，再将板体底部开口后便可形成上述的桌板本体；或者，桌板本体可以采用金属材质，使用模具直接获得内部中空且底部具有开口的板体。另外桌板本体还可以使用塑料、陶瓷材料制成。
参照图3和图4，基于上述实施例，在本发明的一个实施例中，面板110底部设有横梁140，支撑框架300通过横梁140装配在空腔400内。
横梁140对支撑框架300具有限位作用，可以限制支撑框架300在空腔400内部的位移，以方便支撑框架300的安装，此外横梁140还可以作为加强桌板本体100强度的加强筋。
作为优选的，桌板本体100为木质材料，即面板110、挡板120和横梁140均为木质材质制成，支撑框架300为金属框架，在进行支撑框架300的安装时，先在支撑框架300的两侧固定安装横梁140，通过螺钉在横向方向实现二者的固定连接，横梁140则通过黏连的方式固定安装于面板110底部，避免通过打孔的方式将支撑框架300安装在面板110上，且横梁140和面板110均为木质材 料，通过黏连的方式二者之间的连接强度较大，而金属材料与木质材料之间黏连的话连接强度不高且在经过一段时间后容易分离，因此不适合并不适合采用黏连的方式。当然，横梁也可以与挡板或是同时与面板和挡板黏连。
当然直接通过螺钉将支撑框架固定在面板上也可以能够实现支撑框架在桌板本体上安装牢固。
支撑框架300除了用于连接升降立柱200外，还安装有用于控制升降立柱200运动的控制器210，参照图2，基于上述实施例，在本发明的一个实施例中，控制器210通常设置于升降立柱200外，其具有较大的体积，为了减少控制器210在桌板本体100上的凸出程度，控制器210在第一装配口410处与支撑框架300连接，以方便控制器210的拆装，这样一来使得控制器210至少部分能够容纳于空腔400内，以缩减整个桌板本体100部分的厚度。此外，也可以在桌板本体100的下表面设置第二装配口420，控制器210在第二装配口420处与支撑框架300连接，为了减少挡板120上的开口数量，控制器210设置于升降立柱200与支撑框架300连接位置的附近，使第一装配口410和第二装配口420连通。
此外，在桌板本体100上还安装有覆盖控制器210的防护盖板220，防护盖板220安装在支撑框架300或桌板本体100上，防护盖板220能够遮挡控制器210，减少灰尘等杂质会进入到空腔400内，防护盖板220还可以起到对控制器210的支撑作用，当控制器210与支撑框架300的配合出现松动时，防护盖板220能支撑控制器210使其保持在空腔400内，此外防护盖板220还能防止用户误触控制器210，避免出现触电事故。
参照图3至图5，基于上述实施例，在本发明的另一个实施例中，具体说明了控制器210在支撑框架300上的安装结构。
控制器210与支撑框架300之间为可拆连接结构，以方便对升降桌进行维护，具体的，控制器210和支撑框架300其中之一设有卡槽310，另一个设有滑块230，控制器210通过卡槽310与滑块230的配合插装在框架上，通过卡槽310与滑块230配合的方式，控制器210的拆装方式简单，方便用户操作。防护 盖板220对控制器210还具有在横向方向的限位作用，防止控制器210相对支撑框架300出现滑动而导致二者分离。
或者，控制器通过螺钉固定在支撑框架上，通过螺钉固定的方式，控制器在支撑框架的连接结构较为牢固，二者之间不易分离。
或者，控制器粘连在支撑框架上，通过粘贴的方式对控制器进行固定，安装时只需要将控制器对准第二装配口塞入到空腔内即可，可以采用魔术贴的方式进行黏连，也可以通过粘连剂进行黏连。
参照图1和图5，电动升降桌还包括手控器240，手控器240用于输入控制信号，并将控制信号传递至控制器210来实现升降立柱200的运动控制，在上述实施例的基础上，在本发明的一个实施例中，桌板本体100的上表面、侧部、下表面其中之一设置第三装配口241，手控器240嵌入式安装于第三装配口241，手控器241镶嵌在桌板本体100上，方便用户操作，且不会占据额外空间。
手控器240与控制器210通过电线250连接来传递信号，电线250布置在空腔400内，不会显露于桌板本体100外，从而进一步提升升降桌的外观。为了方便电线250的布置，空腔400内通过横梁140限定形成方便电线250布置的走线槽430。
桌板的升降运动由升降立柱200实现，同时桌板也是由升降立柱200进行支撑的，作为优选的，桌板本体100底部设有两个升降立柱200，桌板本体100上对应两个升降立柱200设有两个支撑框架300和两个第一装配口410，通过两个升降立柱200来支撑、驱动桌板，能使桌板在升降过程中保持平稳，在桌板本体100上设置两个支撑框架300来与升降立柱200进行配合，两个支撑框架300之间存在间距，虽然在桌板本体100内部仅设置一块能够与所有的升降立柱200配合的支撑框架300也能实现升降立柱200的装配，但会增加整个桌板本体100部分的重量和支撑框架300的安装难度。
为了实现两个升降立柱200能同时进行升降运动，两个升降立柱200之间 需要进行同时输入控制信号，控制器210的数量只需要设置一个，通过使用电线250分别将升降立柱200和控制器210进行连接即可，电线250能够传递信号，以向两个升降立柱200同时发出上升、下降的控制指令，从而控制桌板本体100的升降运动，电线250布置在空腔400内，这样一来不需要在桌板本体100的下表面上布置线路，提升升降桌的外观。
两个升降立柱200的其中一个与控制器210连接在同一个支撑框架300上，另一个升降立柱200则与控制器210之间存在一定的距离，因此电线250需要在空腔400内延伸，作为优选的，电线250的外壳为橡胶材质，为了避免电线250扭曲，电线250被设置为沿着横梁140布置，并通过黏连的方式固定在横梁140上。
支撑框架300可以支撑桌板本体100以增强桌板本体100的强度，由于桌板本体100内部设置了空腔400导致桌板本体100的强度下降，两个支撑框架300之间的桌板本体100部分缺少支撑框架300的支撑，强度不如安装了支撑框架300的部分，为了保证桌板本体100结构稳定性，两个支撑框架300之间通过支撑架260连接，通过布置支撑架260可以进一步增强支撑框架300的强度。
为了方便电线250与升降立柱200的连接，支撑框架300上设有固线槽270，电线250卡装在固线槽270内，固线槽270对电线250具有限位作用，以方便电线250的布置，此外，固线槽270能使得电线250直接穿过支撑框架300，电线250在连接升降立柱200时，不需要在竖直方向绕过支撑框架300的边缘位置而进入或伸出支撑框架300，避免桌板本体100的厚度因电线250的布置而增加。
当然，升降立柱的数量也可以为更多个，例如三个、四个。
参照图6，为了加强桌板本体100的强度，提高其抗弯曲性能，基于上述实施例，在本发明的一个实施例中，空腔400内还设有支撑于面板110和挡板120之间的支撑件150，支撑件150与面板110和/或挡板120相抵或相连，以方便挡板120的安装，同时支撑件150也得到了限位，并加固了桌板本体100的结 构，提高桌板本体100的抗弯曲性能。
其中，在空腔400内，内除安装支撑框架300外的部分均布置有支撑件150，从而使得整个桌板本体100具有较高的强度。
支撑件150的材质有着多种选择，作为优选的，支撑件150为蜂窝状的纸板，纸板重量轻、价格低，蜂窝状的纸板具有较高的承载性能，从而能够增强桌板本体100的强度，同时纸板本身为纤维材质，对震动具有较好的吸收效果，而纸板上蜂窝状的孔洞也提高了对震动的吸收能力，这样一来当用户在使用过程中，桌板本体100受到撞击时，其表面会产生撞击的声音以及震动波，而震动波在桌板本体100内部传递过程中会被支撑件150所吸收，从而降低了噪音，提高用户的使用体验，此外升降立柱200在升降运动过程中产生的震动也可以被支撑件150吸收，减少了桌板本体100的晃动。此外，也可以采用塑料、橡胶等结构代替纸板。支撑件还可以为发泡层，发泡层由发泡材料制成，具有更好的减震能力，发泡材料成本低、重量轻，发泡材料形成的支撑件，其本身不易弯曲，设置于桌板本体内以加强桌板本体的抗弯曲性能，发泡材料为一种填充材料，可以先将桌板本体完成组装后再填入发泡材料，形成黏连在挡板和面板上的发泡层，提高挡板的安装强度。或者，支撑件为加强筋，则具有极强的抗弯曲性能，可以最大程度提高桌板本体的物理强度。
通常，升降立柱200上驱动电机的安装位置有着多种情况，参照图1和图2，基于上述实施例，在本发明的一个实施例中，作为优选的，驱动电机设置于升降立柱200内部，因此驱动电机不会影响到桌板本体100结构，提高桌板本体100的适配性。
或者，驱动电机与升降立柱的上端连接，并通过传动机构传递动力，驱动电机安装在支撑框架上，传动机构设置于立柱内部，第一装配口可以方便驱动电机在支撑框架上的拆装。
或者，电动升降桌采用单电机来同时驱动两个升降立柱的升降运动，可以节省一个驱动电机的成本，两个升降立柱之间设有装配在支撑框架上用于传递 动力的传动部件，驱动电机桌板本体设于下方与传动部件传动连接，传动部件、驱动电机通过第一装配口安装到支撑框架上。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，熟悉该本领域的技术人员应该明白本发明包括但不限于附图和上面具体实施方式中描述的内容。任何不偏离本发明的功能和结构原理的修改都将包括在权利要求书的范围中。
