具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本申请实施例的组件可以以各种不同的配置来布置和设计。
在本发明的描述中，需要理解的是，术语“中心”、“长度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
需要说明的是，在不冲突的情况下，本申请的实施例中的特征可以相互结合。
超短焦距的投影设备是可以在0.7米左右的距离内投射出100寸甚至更大的画面。投影时，需要投影仪的投影画面位置和投影屏幕位置完全对应，才可以获得较好的投射效果。
对于超短焦距的投影设备，投影仪的位置微小移动往往会导致投影画面偏移较多。且在安装投影设备时，需要手动将投影画面调整到投影屏幕的合适位置。
然而，调节投影画面时，需要反复调整投影画面的位置，采用手动调节的方式精确性较差，且反复调整比较麻烦，导致调节效率低下。
基于上述问题，请参照图1，本申请实施例提供了一种投影设备位置调节支架100。该投影设备位置调节支架100可以沿第一轴101的延伸方向进行高度调节、绕第一轴101摆动进行角度调节、绕第二轴103摆动进行俯仰调节、绕第三轴105摆动进行俯仰调节等。需要说明的是，在本发明的实施例中，第一轴101、第二轴103及第三轴105可以分别对应坐标系中的Z轴、X轴及Y轴。其中，第一轴101、第二轴103及第三轴105可以两两垂直，也可以两两不垂直。当第一轴101、第二轴103及第三轴105两两垂直时，第二轴103和第三轴105所形成的平面可以为水平面，第二轴103和第三轴105可以在水平面内分别沿相互垂直的两个方向水平延伸；第二轴103和第一轴101所形成的平面、第三轴105和第一轴101所形成的平面可以为竖直面，第一轴101可以在竖直面内沿竖直方向延伸。
可以理解的是，第一轴101的延伸方向可以是投影设备位置调节支架100的高度方向，第二轴103的延伸方向可以是投影设备位置调节支架100的长度方向，第三轴105的延伸方向可以是投影设备位置调节支架100的宽度方向。
本申请实施例提供的投影设备位置调节支架100可以适用于100寸甚至更大尺寸的投影设备160，可以应用于家用投影仪和工程投影仪，对需要调节位置的家用或工程投影仪进行位置调节。或者，也可以集成在激光电视柜里面与激光投影仪成套使用、在大型投影机内部与工程投影机集成为一体使用等。本申请实施例提供的投影设备位置调节支架100应用范围较广，例如，在家庭、办公室、学校、娱乐场所等场景中均可以使用，本申请对其应用场所不做限定。
请继续参照图1，投影设备位置调节支架100可以包括固定座110、第一调节机构130以及第二调节机构140。其中，固定座110用于承载并固定 投影设备160，为投影设备160提供支撑作用，投影设备160放置或者装设于固定座110的顶部。第一调节机构130安装在固定座110的下方，用于驱动固定座110带动投影设备160绕第一轴101转动，即调节投影设备160在左右方向上的角度位置。第二调节机构140设置于第一调节机构130的下方，用于驱动第一调节机构130带动固定座110升降运动或者俯仰运动，即调节投影设备160在竖直方向的高度位置和上下方向上的角度位置。
具体的，请参照图2、图3及图4，固定座110为薄板状结构，包括上下相对的第一面112和第二面114。投影设备160固定安装于固定座110第一面112的中间位置。
可选地，如图2所示，固定座110的第一面112与投影设备160安装区域125相对应的转角位置设置有安装标识贴118。其中，安装标识贴118所围合成的区域正好与投影设备160的大小相匹配，使得用户在安装投影设备160时，可以对比安装标识贴118的位置对投影设备160的位置进行角度调整，从而可以获得比较理想的固定位置。
进一步地，固定座110的第一面112的表面上也可以贴设硅胶防滑垫，有利于投影设备160稳固地安装于固定座110上。
考虑到目前投影设备160的型号、大小、规格不完全一致，为了提高该投影设备位置调节支架100的通用性，使其可以适用于多种规格的投影设备160。在可选的一实施例中，请参照图3，固定座110的第一面112设置有开合夹具120。开合夹具120可以在一定的尺寸范围内弹性调节，用以适用不同大小的投影设备160。
开合夹具120可以包括第一夹持机构127和第二夹持机构129。第一夹持机构127和第二夹持机构129均成对设置，且第一夹持机构127沿第一方向121相对设置，第二夹持机构129沿第二方向123相对设置。相对设置的第一夹持机构127沿第一方向121可滑动的连接于固定座110，相对设置的第二夹持机构129沿第二方向123可滑动的连接于固定座110。其中，第一方向121与第二方向123具有夹角，通过第一夹持机构127和第二夹持机构129围成用于固定投影设备160的安装区域125。由于第一夹持机构127和第二夹持机构129相对于固定座110均为弹性连接，安装投影设备 160后，在第一夹持机构127和第二夹持机构129的弹性夹持作用下，投影设备160可以自然地被夹紧定位至固定座110的中间位置。
具体地，第一夹持机构127可以包括挡块1271和第一弹性件1273。挡块1271沿与第一方向121垂直的方向延伸布置，第一弹性件1273弹性连接于挡块1271背离安装区域125的一面，第一弹性件1273为挡块1271提供预紧推力，以使挡块1271可以夹紧位于安装区域125内的投影设备160。与挡块1271相匹配地，固定座110沿第一方向121设置有滑动部1275，挡块1271可滑动的连接于滑动部1275。
可以理解的是，当滑动部1275为滑槽时，挡块1271包括了与滑槽相匹配的滑块，滑块嵌设于滑槽内。在第一弹性件1273的预紧推力下，挡块1271沿滑槽向安装区域125滑动，从而将位于安装区域125内的投影设备160夹紧定位。当滑动部1275为滑轨时，挡块1271包括了与滑轨相配合的滑槽，挡块1271卡设于滑轨上。在第一弹性件1273的预紧推力下，挡块1271沿滑轨的延伸方式向安装区域125滑动，从而将位于安装区域125内的投影设备160夹紧定位。考虑到安装区域125内安装投影设备160，当滑动部1275为滑轨时，滑轨有可能会与投影设备160发生干涉，不利于投影设备160的安装稳固性。在本申请实施例中，滑动部1275采用滑槽的结构设计。
进一步地，第二夹持机构129可以包括弹簧限位块，弹簧限位块设置于安装区域125沿第二方向123的两侧。弹簧限位块可以包括限位块和第二弹性件，第二弹性件与限位块弹性连接，且第二弹性件位于限位块远离安装区域125的一面，第二弹性件用于为限位块提供预紧推力。且第一夹持机构127、第二夹持机构129所形成的安装区域125的中心位置与第一传动件116的中心位置重合。
可以理解的是，第一弹性件1273的回弹位移、滑动部1275的长度以及投影设备160沿第一方向121的尺寸调节范围相匹配。换句话说，第一弹性件1273推动挡块1271沿滑动部1275的滑动长度应满足不同投影设备160沿第一方向121的尺寸调节范围，通过第一夹持机构127对投影设备160沿第一方向121进行限位。同理，弹簧限位块的回弹位移和投影设备 160沿第二方向123的尺寸调节范围相匹配，通过第二夹持机构129对投影设备160沿第二方向123进行限位。
可选地，第一方向121和第二方向123垂直，且第一方向121与投影设备160的一个侧面平行，第二方向123与投影设备160的另一侧面平行，从而可以将不同规格、尺寸的投影设备160夹持定位在安装区域125的中心位置。需要注意的是，当投影设备160的外形结构为例如圆形、三角形等其他形状时，第一夹持机构127和第二夹持机构129的具体结构可以进行适应性更改，以实现夹紧投影设备160的目的。本申请对此不作具体限定，只要满足通过开合夹具120可以将投影设备160夹紧固定在安装区域125的中心位置即可。
请一并参见图4，固定座110第二面114固定连接有第一传动件116，即第一传动件116和投影设备160分别位于固定座110背对的两面。第一传动件116用于配合第一调节机构130并带动固定座110绕第一轴101转动。
可选地，第一传动件116安装于固定座110的中心位置，且第一传动件116的转轴1161和投影设备160的安装轴(图中未示出)重合。
请参照图5、图6及图7所示，第一调节机构130设置于固定座110靠近第一传动件116的一面，第一调节机构130可以包括第一调节座131、第一驱动组件133以及第二传动件137。第一驱动组件133和第二传动件137分别设置于第一调节座131上，其中，第一驱动组件133与设置于固定座110上的第一传动件116传动连接，用于向第一传动件116提供驱动力。第二传动件137用于和第二调节机构140传动连接，以使第二传动件137在第二调节机构140的驱动作用下传动运动，进而带动固定座110同步运动。
具体地，第一驱动组件133包括第一驱动件1331和与第一驱动件1331传动连接的第一齿轮1333，第一齿轮1333与第一驱动件1331的动力输出轴键连接，以使第一驱动件1331带动第一齿轮1333同步转动。与第一驱动组件133相配合的，第一传动件116包括转轴1161和第二齿轮1163(如图3)。转轴1161与固定座110固定连接，第二齿轮1163与转轴1161键连接，且第二齿轮1163与第一驱动组件133中的第一齿轮1333啮合传动。 以使第一驱动件1331驱动第一齿轮1333转动，第一齿轮1333带动第二齿轮1163转动，第二齿轮1163带动转轴1161转动以使得固定座110绕第一轴101同步转动。
可选地，第一驱动件1331采用步进电机，可以正反转，从而带动固定座110绕第一轴101沿顺时针或逆时针摆动。通过设置步进电机的转速和时长，可以实现固定座110带动投影设备160绕第一轴101在±10度范围内的摆动。可以理解的是，固定座110带动投影设备160绕第一轴101的摆动角度可以根据实际需求调节，例如，可以设置为绕第一轴101在±5度范围内摆动，具体的摆动角度不做限定，根据投影设备160实际使用场合和实际需要调节范围而定。
可选地，第一齿轮1333采用小齿轮，第二齿轮1163采用大齿轮。步进电机的动力输出轴与小齿轮键连接实现同步转动，通过小齿轮和大齿轮的啮合传动，将动力传递至大齿轮且带动大齿轮转动。由于小齿轮的齿数小于大齿轮的齿数，进而在啮合传动时，小齿轮的转速大于大齿轮的转速，从而可以降低第一驱动组件133的输出转速。通过步进电机的动力输出轴的转动来控制固定座110的摆动方向和摆动角度，且通过小齿轮和大齿轮的啮合传动，有利于提高固定座110沿第一轴101摆动时的角度调节精度。
为了避免第一齿轮1333和第二齿轮1163由于安装误差而导致配合时出现轴向错位的情况。可选地，第一齿轮1333的齿宽大于第二齿轮1163的齿宽，配合安装时即使存在一些安装误差，也可以保证第一齿轮1333和第二齿轮1163的实际啮合齿宽，有利于提高齿轮的连接强度，增加使用寿命。
第一齿轮1333和第二齿轮1163的传动比等于第二齿轮1163的齿数与第一齿轮1333的齿数之比。可以理解的是，在第一齿轮1333和第二齿轮1163啮合传动中，当第一齿轮1333和第二齿轮1163的传动比过大时，第二齿轮1163的尺寸较大，导致调节支架整体体积大，且第二齿轮1163加工不方便；当第一齿轮1333和第二齿轮1163的传动比过小时，齿轮的减速效率较低。为了避免上述弊端，第一齿轮1333和第二齿轮1163的传动比应避免过大或者过小，可选地，传动比应根据电机和结构设计的需求进 行适应性选择。
本申请实施例提供的投影设备位置调节支架100，使用时放置于桌面上，投影设备160安装于固定座110上。通过第一驱动组件133驱动第一传动件116转动，为了在转动过程中对固定座110提供一定的支撑作用，可选地，第一驱动组件133还包括组合轴承1335。请参照图6，组合轴承1335固定连接于第一调节座131，第一传动件116中的转轴1161远离固定座110的一端可转动的穿设于组合轴承1335中。组合轴承1335固定、支撑固定座110及投影设备160，且固定座110可以在齿轮传动作用下，通过组合轴承1335相对于第一调节机构130实现更加顺畅的转动。组合轴承1335既可以承受轴向力，也可以承受径向力，可选地，组合轴承1335可以采用推力轴承和滚动轴承的组合，进而实现传动精度高、噪音小的目的。
请参照图7和图8，第二调节机构140位于第一调节机构130的背离固定座110的一面。第二调节机构140可以包括第二调节座141和第二驱动组件143，第二驱动组件143设置于第二调节座141上，且第二驱动组件143和第二传动件137传动连接，用于驱动第一调节机构130带动固定座110沿第一轴101升降运动、或者通过设置多个第二驱动组件143并相互配合以带动固定座110俯仰运动从而实现俯仰角度的调节。
可选地，第一调节机构130上的第二传动件137与第二调节机构140上第二驱动组件143的数量相同且一一对应。为了实现沿第一轴101升降运动或者俯仰运动，第二传动件137的数量为至少三个，且至少三个第二传动件137不位于同一直线上。当第二传动件137的数量为三个，且不位于同一直线上时，三个第二传动件137形成三角形形状。
当第二驱动组件143驱动全部第二传动件137上升到的高度位置全部相等时，第一调节机构130带动固定座110相对于第二调节机构140平行，仅是沿第一轴101方向上高度不同，即带动固定座110和投影设备160沿第一轴101进行升降运动。
当第二驱动组件143驱动全部第二传动件137上升到的高度位置不完全相等时，第一调节机构130带动固定座110相对于第二调节机构140倾斜，也就是说，第一调节机构130带动固定座110及投影设备160相对于 第二调节机构140可以绕第二轴103或第三轴105做俯仰运动，以调节投影设备160的投影画面在竖直方向上的角度。
可选的，第二驱动组件143包括第二驱动件1431和螺杆1433，螺杆1433与第二驱动件1431传动连接。螺杆1433连接于第二调节座141且沿第一轴101方向延伸，通过螺杆1433与第二传动件137传动连接，能够将螺杆1433的转动转化为第二传动件137沿螺杆1433轴向的移动。
具体地，请参照图9，第二传动件137可以包括外圈1371、螺母1373、第一滑移轴1375以及第二滑移轴1377。螺母1373可转动的套设于螺杆1433上，螺母1373随螺杆1433的转动转换为沿螺杆1433轴向的移动。同时，螺母1373可转动的嵌设于外圈1371内，第一滑移轴1375和第二滑移轴1377呈十字状连接于外圈1371的径向。连接时，第一滑移轴1375连接于外圈1371沿径向的两侧，且第一滑移轴1375可滑动的连接于第一调节座131；第二滑移轴1377沿径向穿设于外圈1371后与螺母1373可转动的连接，以使螺母1373在沿螺杆1433轴向运动时，外圈1371可以相对于螺母1373绕第二滑移轴1377转动。
可选地，第一滑移轴1375与第二滑移轴1377之间具有夹角，第二滑移轴1377用于使外圈1371绕第二滑移轴1377转动，第一滑移轴1375用于带动外圈1371沿第二滑移轴1377轴向移动。可以理解的是，第一滑移轴1375与第二滑移轴1377可以垂直，也可以为基本垂直。
由于第一滑移轴1375可以带动外圈1371沿其轴向移动，可选地，第二传动件137还包括固定件1379。固定件1379固定连接于第一调节座131上，固定件1379开设有贯通的滑动孔，第一滑移轴1375可滑动的穿设于滑动孔，在滑动时，第一滑移轴1375带动外圈1371同步滑动。当第二驱动组件143驱动第二传动件137运动时，可以针对至少三个第二传动件137运动的不同状态进行自动调节，以避免出现卡顿、调节不畅的问题。
下面以第二传动件137的数量为三个为例进行详细说明。请参照图7和图10，三个第二传动件137的中心轴线依次连接形成正三角形形状。
第一种情况：当三个第二驱动组件143一一对应的驱动三个第二传动件137同步运动且运动的速度和运动后的高度位置相同时，第一调节机构 130带动固定座110相对于第二调节机构140沿第一轴101方向平行移动，即实现了投影设备160的高度位置的调节。在调节过程中，第二驱动件1431驱动螺杆1433转动，螺母1373沿螺杆1433的轴向移动，螺母1373与外圈1371之间不会发生相对运动。
第二种情况：在图7视角下，当位于下方的两个第二传动件137的运动速度和运动后的高度位置相同，但其与位于上方的第二传动件137的运动速度和运动的高度位置不相同时，第一调节机构130带动固定座110相对于第二调节机构140绕位于下方的两个第二传动件137的中心轴线的连线俯仰运动，以使第一调节机构130带动固定座110相对于第二调节机构140倾斜。
同理，当三个第二传动件137中仅有两个第二传动件137运动后的高度位置相同，可以实现第一调节机构130带动固定座110相对于第二调节机构140绕高度位置相同的两个第二传动件137的中心轴线的连线做俯仰运动。
第三种情况：当三个第二传动件137运动后的高度位置均不相同时，根据三点构成一个平面，可以任意的调节第一调节机构130带动固定座110相对于第二调节机构140在不同方位上的角度俯仰运动。
针对上述第二种情况和第三种情况而言，第一调节机构130相对于第二调节机构140倾斜设置，由于螺母1373可转动的连接于螺杆1433，螺杆1433是垂直连接于第二调节座141上。在该情况下，一方面，外圈1371会相对于螺母1373绕第二滑移轴1377转动一角度，且转动后外圈1371与螺母1373之间的夹角与第一调节座131和第二调节座141之间的夹角相等。另一方面，外圈1371会随第一滑移轴1375沿固定件1379的滑动孔滑动一距离，且移动后外圈1371位于螺杆1433的正上方，外圈1371通过第一滑移轴1375的滑动来补偿第一调节座131相对于第二调节座141倾斜产生的沿水平面的偏移，以使螺杆1433带动螺母1373传动时不会发生卡死现象，进而避免联动调节时的干涉问题。
进一步地，请继续参照图9，针对上述第一种情况时，为了使得第二传动件137在第二驱动组件143的驱动作用下，外圈1371和螺母1373可以 自动调节居中。在第一滑移轴1375和第二滑移轴1377上均设置有弹性件，套设于第一滑移轴1375上的弹性件位于固定件1379的远离外圈1371的一面，套设于第二滑移轴1377上的弹性件被压缩于外圈1371和第二滑移轴1377端部的凸起之间，从而实现第一调节机构130和固定座110相对于第二调节机构140平行时可以保持螺母1373居中，且不会随意滑动的目的。
可选地，第一调节座131和第二调节座141可以均为盒状结构(如图10)，第一驱动组件133、组合轴承1335以及第二传动件137均可以嵌设于第一调节座131的盒体内。第二驱动组件143中的第二驱动件1431可以嵌设于第二调节座141的盒体内，螺杆1433垂直于第二调节座141与第二传动件137传动连接。减少传动机构的数量，减小整体体积。
该投影设备位置调节支架100采用固定座110、第一调节机构130以及第二调节机构140三层结构设计，可以实现沿第一轴101的高度调节、绕第一轴101转动的角度调节、绕第二轴103转动的俯仰调节以及绕第三轴105转动的俯仰调节。调节精确、体积较小、有利于产品的轻薄型发展趋势。通过第二传动件137的结构设计，可以保证螺母1373在与螺杆1433传动配合时，外圈1371在第一调节座131上的偏转和滑移较小，且结构简单；另外，通过将驱动件内置，进一步减小整体体积。
进一步地，本申请实施例提供的投影设备位置调节支架100可以采用无刷直流PWM(Pulse Width Modulation，脉冲宽度调制技术)控制，以实现闭环控制。脉冲宽度调制技术是一种模拟控制方式，其根据相应载荷的变化来调制晶体管基极或MOS管栅极的偏置，来实现晶体管或MOS管导通时间的改变，从而实现开关稳压电源输出的改变。这种方式能使电源的输出电压在工作条件变化时保持恒定，是利用微处理器的数字信号对模拟电路进行控制的一种非常有效的技术。
作为另一种实施方式，可选地，请参照图11，投影设备位置调节支架100还可以包括第三调节机构150。第三调节机构150连接于第二调节机构140的背离第一调节机构130的一面，第三调节机构150用于带动第二调节机构140、第一调节机构130、固定座110以及投影设备160整体在桌面上沿第二轴103或第三轴105移动，即实现整体行走的作用。
具体地，请参照图12和图13，第三调节机构150包括驱动轮组件155，驱动轮组件155可以带动第二调节机构140、第二调节机构140带动第一调节机构130，进而第一调节机构130带动固定座110沿第二轴103的延伸方向直线运动。
具体地，第三调节机构150还包括第三调节座151和支撑轮153，第三调节座151设置于第二调节机构140的背离第一调节机构130的一面。第三调节座151为板状结构，且第三调节座151开设有穿设孔1510。支撑轮153可转动的连接于第三调节座151背离第二调节机构140的一面，支撑轮153的数量为多个，多个支撑轮153位于第三调节座151的周向。驱动轮组件155连接于第三调节座151靠近第二调节机构140的一面，且驱动轮组件155可以穿过第三调节座151的穿设孔1510与桌面或者工作面接触。当驱动轮组件155工作时，驱动轮组件155可以带动调节支架整体沿桌面或者工作面运动。
进一步地，驱动轮组件155可以包括传动连接的第三驱动件1551和驱动轮1553。第三驱动件1551连接于第三调节座151，驱动轮1553穿设于穿设孔1510且其底面与支撑轮153的底面位于同一平面上，第三驱动件1551驱动驱动轮1553转动以带动投影设备位置调节支架100沿某一方向直线运动。
可选地，支撑轮153可以为万向轮，起支撑滚动的作用。第三驱动件1551用于驱动驱动轮1553转动，且第三驱动件1551可以正反转。当投影设备位置调节支架100设置于桌面上，在重力作用下，驱动轮1553与桌面接触且具有一定的摩擦力，通过第三驱动件1551可以使驱动轮1553沿桌面以某一方向前后直线运动。
为了使得该投影设备位置调节支架100在桌面上直线运动时具有转向功能，可选地，第三调节机构150还可以包括设置于第三调节座151上的转向轮组件157，转向轮组件157与驱动轮组件155传动连接，以使驱动轮组件155绕第一轴101转向。
具体地，转向轮组件157包括第四驱动件1571、蜗轮1573及蜗杆1575。其中，第四驱动件1571的动力输出轴和蜗杆1575传动连接，蜗杆1575与 蜗轮1573传动连接。在第四驱动件1571的驱动力的作用下，蜗杆1575的转动能够转换为蜗轮1573的转动，且将蜗杆1575的转动方向转变为相互垂直的蜗轮1573的转动方向。
工作时，驱动轮组件155固定连接于蜗轮1573上，且驱动轮组件155随蜗轮1573可以同步转动，以使驱动轮组件155绕第一轴101可以转向。第四驱动件1571通过蜗杆1575可以驱动蜗轮1573正反旋转，且旋转的角度可以达到360度范围。当调节支架需要沿第二轴103方向行走时，第四驱动件1571通过蜗杆1575驱动蜗轮1573转动，以使驱动轮组件155中的驱动轮1553的径向平行于第二轴103，第三驱动件1551驱动驱动轮1553沿第二轴103方向前后直线运动。当调节支架需要沿第三轴105方向行走时，第四驱动件1571通过蜗杆1575驱动蜗轮1573旋转90度，蜗轮1573带动驱动轮组件155整体旋转90度，以使驱动轮组件155中的驱动轮1553的径向平行于第三轴105。然后，第三驱动件1551驱动驱动轮1553沿第三轴105方向前后直线运动。
换句话说，第三调节机构150通过驱动轮组件155带动调节支架整体在一定范围内相对桌面或工作台实现前后等直线上的位置调节；通过转向轮组件157带动调节支架整体在一定范围内相对桌面或工作台转向，从而实现前后、左右方位等任意角度的行走，以使投影设备160的投影图像与投影屏幕位置匹配的更加理想。
可以理解的是，为了避免第二调节座141与驱动轮组件155或转向轮组件157发生干涉，也为了减小整体结构的体积，可以将驱动轮组件155和转向轮组件157安装于第三调节座151上。可选的，第二调节座141开设有与驱动轮组件155和转向轮组件157相匹配的让位孔1410，以使驱动轮组件155和转向轮组件157可以穿过让位孔1410，不会与第二调节座141发生干涉，减小整体结构的高度，也同时减少了整体结构的重量。
本申请实施例提供的投影设备位置调节支架100，由于驱动轮组件155和转向轮组件157均嵌设于第三调节座151和第二调节座141之间形成的空间内，结构紧凑，体积较小。同时，由于采用固定座110、第一调节机构130以及第二调节机构140三层结构设计，能够实现投影设备160沿第一轴 101的高度调节、绕第一轴101转动的角度调节、绕第二轴103转动的俯仰调节、绕第三轴105转动的俯仰调节、沿第二轴103的位置调节以及沿第三轴105的位置调节。整体方案不仅体积轻巧，而且可以达到多方位的智能调节，适用于家用激光投影仪。
本申请实施例提供的投影设备位置调节支架100，可以实现智能四轴或六轴位移和角度调节，有利于将投影设备160的投影图像与投影屏幕调整的更加理想，结构紧凑，位置或角度调节精确，进一步提高了调节效率。
