请参阅图4和图3，支撑板111作为爬行垫10的底层，用于支撑压力传感层12、弹性层13、发光元件层14、弹性透光层15和控制组件17等；同时支撑 组件11还起到防滑的作用。在一些实施方式中，支撑板111可以是弹性板，如可以是弹性泡棉等。在一些实施方式中，支撑板111上开设有开口朝向压力传感层12的容置槽1111，以用于容置局部的控制组件17。通过设置容置槽1111，可以有效的降低因为控制组件17的存在而导致爬行垫10有凸起感或者硬物硌脚/手感，进而有效地提高婴幼儿在爬行垫10上的爬行体验。
请参阅图3和图4，在一些实施方式中，支撑组件11还包括中空边框112，中空边框112也可以用弹性材质制成，如可以是硅胶或者弹性泡棉等。在一些实施方式中，中空边框112为多边形框体，如可以是正三角形中空框体、正方形中空框体、长方形中空框体、棱形中空框体、正五边形中空框体、正六边形中空框体、正八边形中空框体、正十边形中空框体、正十六边形中空框体中的至少一种。如可以是多种多边形框体的组合，从而可以极大地提高爬行垫10的拼接空间利用率。
请参阅图5、图7和图3，在一些实施方式中，中空边框112包括多块换向连接件1121和数量与换向连接件1121的数量相同的边板1122，每个换向连接件1121都与两个边板1122连接；由换向连接件1121和边板1122围合形成中空边框112，支撑板111、压力传感层12、弹性层13、发光元件层14、弹性透光层15以及控制组件17都设于中空边框112的中空部位。在一些实施方式中，支撑板111与中空边框112连接。在一些实施方式中，至少支撑板111、弹性层13以及弹性透光层15都与中空边框112连接，从而有效提高爬行垫10结构的可靠性。
请参阅图7、图5、图1和图2，在一些实施方式中，每个换向连接件1121都包括第一连接部11211和第二连接部11212。其中，第一连接部11211的一端与第二连接部11212的一端连接，第一连接部11211的另一端与一块边板1122连接，第二连接部11212的另一端与另一块边板1122连接，并且第一连接部11211和第二连接部11212相互不平行，即成非180°角度或非0°角度连接的状态，从而使得换向连接件1121实现换向连接，并与多个边板1122围合形成中空结构。在一些实施方式中，每个接口组件16的局部外露于换向连接件1121外。在一些实施方式中，第一连接部11211上开设有第一安装孔(图中未标示)，第二连接部11212上开设有第二安装孔(图中未标示)，第一安装孔的中心轴与支撑板111 平行，第二安装孔的中心轴与支撑板111平行，并且第一安装孔的中心轴与第二安装孔的中心轴共面相交，接口组件16的局部穿设于第一安装孔和第二安装孔中并延伸至换向连接件1121外，以便于一个爬行垫10与另一个爬行垫10进行拼接。
请参阅图4、图5以及图6和图3，每个边板1122都包括板主体11221、第一限位板11222、第二限位板11223和多组定位凸块组11224，其中，第一限位板11222和第二限位板11223设于板主体11221的两相对边缘，由第一限位板11222和第二限位板11223将至少支撑板111、弹性层13以及弹性透光层15都限制在中空边框112里；第一限位板11222和第二限位板11223均自板主体11221朝中空边框112之中心轴的方向延伸。每组定位凸块组11224都包括至少三个定位凸块，同一组的定位凸块沿第一限位板11222至第二限位板11223的方向间隔分布于板主体11221上，且均自板主体11221朝向中空边框112之中心轴方向凸设。在一些实施方式中，支撑板111的边缘开设有与定位凸块组11224卡接定位的第一缺口1112，从而有效提高爬行垫10的结构可靠性。
请参阅图11、图12及图7和图2，在一些实施方式中，每个接口组件16都包括一个接头件161。一个接头件161上都包括公接头1611和母接头1612，并且公接头1611和母接头1612中的一者安装在第一安装孔上，另一者则安装在第二安装孔上，从而有利于当多个爬行垫10进行拼接时实现相邻的爬行垫10电性连接。在一些实施方式中，每个接口组件16还包括第三电路板162，第三电路板162安装在弹性层13上，并且第三电路板162通过导线173与第一电路板171电性连接，公接头1611和母接头1612分别与第三电路板162电性连接。爬行垫10中的一个接头件161用于与电源电连接，从而实现对爬行垫10供电，其余的接头件161则用于与其余爬行垫10进行拼接以实现多个爬行垫10之间的电连接和信号传输。
请参阅图3、图11和图12，控制组件17用于控制爬行垫10的工作状态，同时还能检测和记录婴幼儿的运动情况以供育儿的数据分析。在一些实施方式中，控制组件17包括第一电路板171和第二电路板172，第一电路板171与发光元件层14电性连接；第二电路板172与压力传感层12电性连接；第二电路板172与第一电路板171电性连接；多个接头件161通过导线173与第一电路板171 连接。当将多个爬行垫10进行拼接时，接头件161用于将拼接的相邻两个爬行垫10进行电连接。
请参阅图3和图11，在一些实施方式中，压力传感层12包括压电薄膜传感器阵列(图中未标示)，薄膜压力传感器阵列呈多行多列分布在弹性层13与支撑板111之间，并且压电薄膜传感器阵列与第二电路板172电性连接，通过设置压电薄膜传感器阵列，可以对爬行垫10上任意部位受到的压力产生感应，经过反馈给控制组件17后由控制组件17控制发光元件层14产生相应的动态光图，提高婴幼儿在爬行垫10上的爬行趣味性。更为具体地，当压电薄膜传感器阵列受到外部压力时出现电阻变化，第二电路板172通过读取压电薄膜传感器阵列的阻值，再通过第一电路板171的处理，可实现压力传感层12和发光元件层14之间的联动。比如，根据压力传感层12的反馈，发光元件层14会产生运动的光图，使得婴幼儿“抓到”了运动的图案，压力传感层12进一步反馈之后可以产生特殊光效，增加婴儿爬行的趣味性，实现婴幼儿爬行垫10之间的相互闭环交互。当然，作为替代的实施方式，薄膜压力传感器阵列也可以呈多行多列分布在弹性层13与发光元件层14之间。
请参阅图3和图8以及图9，弹性层13在爬行垫10中具有以下几方面的作用，一方面支撑发光元件层14；另一方面保护控制组件17；再一方面，为控制组件17提供定位作用。在一些实施方式中，弹性层13设有第一凹槽131、第二凹槽132以及走线槽133，其中，第一凹槽131的开口朝向发光元件层14，第二凹槽132的开口朝向支撑板111，走线槽133的开口朝向发光元件层14，并且第一凹槽131和走线槽133连通，第一凹槽131的底壁上设有与第二凹槽132连通的贯穿孔130，第一电路板171的局部设于第一凹槽131中，第二电路板172设于第二凹槽132中，且第一电路板171与第二电路板172通过贯穿孔130相互连接，导线173设于走线槽133中，以避免导线173影响婴幼儿在爬行垫10上的爬行体验。在一些实施方式中，弹性层13上具有安装部136，安装部136设置在走线槽133之远离第一凹槽131的端部，第三电路板162安装在安装部136上，从而提高多个爬行垫10相互拼接的拼接可靠性。在一些实施方式中，弹性层13的边缘开设有与定位凸块组11224卡接定位的第二缺口134，从而提高爬行垫10的结构可靠性。当然，作为替代的实施方式，第一凹槽131、第二凹槽 132以及走线槽133也可以设置在支撑板111上，从而可以使得控制组件17相对远离弹性透光层15，以尽可能降低控制组件17对爬行体验感的影响，此时，弹性层13和支撑板111的结构以及控制组件17的走线均应当做适应性的调整。
请参阅图3，在一些实施方式中，发光元件层14包括LED灯板(图中未标示)和匀光板(图中未标示)；匀光板与弹性透光层15连接，LED灯板叠设在匀光板上且与第一电路板171电性连接，LED灯板提供若干个光斑均匀、亮度适中的发光区域，引导婴幼儿进行运动，通过压力传感层12反馈的信息，发光元件层14可以产生一些卡通有趣的运动的组合图案，激发婴幼儿的爬行欲。在一些实施方式中，匀光板通过胶水与弹性透光层15固定连接。
请参阅图10、图3和图1，弹性透光层15具有多方面的作用，第一方面用于保护控制组件17，以防止婴幼儿爬行过程中压坏控制组件17而导致爬行垫10的功能失效；第二方面，提供舒适的爬行触感；第三方面，起到防水防滑防霉变的作用；第四方面，可以进一步实现匀光、透光效果，提高光图变化效果；第五方面，起到弹性缓冲的效果。在一些实施方式中，弹性透光层15可以为半透明硅胶；或者是半透明泡棉和具有亲肤效果的热塑性聚氨酯弹性体橡胶(TPU)，其中，半透明泡棉与发光元件层14连接，而TPU设于半透明泡棉上。在一些实施方式中，弹性透光层15的边缘开设有与定位凸块组11224卡接定位的第三缺口151，从而可以有效提高爬行垫10的结构可靠性。
请参阅图3和图8，在一些实施方式中，爬行垫10还包括弹性盖板18，弹性盖板18盖设在第一凹槽131的槽口上，同时盖设在走线槽133的槽口上，并且弹性盖板18遮盖第一凹槽131和走线槽133，通过弹性盖板18可以提高弹性层13的平整性，降低因为第一凹槽131、走线槽133以及控制组件17的存在而影响婴幼儿在爬行垫10上的爬行体验。
请参阅图3、图4以及图9，在一些实施方式中，爬行垫10还包括磁吸组件19，磁吸组件19包括第一磁吸件191和第二磁吸件192；第一磁吸件191嵌设在弹性层13中，第二磁吸件192嵌设于支撑组件11中，通过第一磁吸件191和第二磁吸件192设置在压力传感层12的两相对表面，从而实现对压力传感层12的磁吸固定，同时也提高支撑板111和弹性层13的连接强度。在一些实施方式中，弹性层13开设有开口朝向压力传感层12的第三安装孔135，第一磁吸件191 安装于第三安装孔135里；支撑板111开设有开口朝向压力传感层12的第四安装孔1113，第二磁吸件192安装于第四安装孔1113里。为了更好的固定第一磁吸件191和第二磁吸件192，还通过胶水将第一磁吸件191固定在第三安装孔135里，以及通过胶水将第二磁吸件192固定在第四安装孔1113里。在一些实施方式中，可以使用其他紧固件来替代磁吸组件19，只要替代磁吸组件19的紧固件不影响婴幼儿的爬行体验均可行，如可以是塑料螺钉、螺栓等。
请参阅图13，图13显示了由九块爬行垫10按照3×3的拼接方式进行拼接的效果。在图13中，其中一块爬行垫10的一个接口组件16用于与电源连接，其余的接口组件16用于与其他爬行垫10进行拼接，从而实现在多个爬行垫10之间进行电连接和信号传输。
请参阅图14、图13以及图3和图11，爬行垫10的控制组件17中还包括控制器174，控制器174设置在第一电路板171上和/或第二电路板172上，控制器174可以是中央处理器(Central Processing Unit，CPU)、微控制器单元(Micro Control Unit，MCU)和微处理器单元(Micro Processor Unit，MPU)、数字信号处理器(Digital Signal Controller，DSC)中的任一种。有的爬行垫10的控制组件17中的控制器174为CPU，有的则为MCU、MPI、DSC中的任一种。
请参阅图14、图13以及图3和图11，通过接口组件16相互拼接的多块爬行垫10中，有一块爬行垫10上的控制组件17的控制器174为CPU，命名为第一控制器1741，其余爬行垫10上的控制组件17的控制器174为MCU、MPI、DSC中的任一种，命名为第二控制器1742。
请参阅图14、图13以及图3和图11，方便说明多块爬行垫10拼接以及工作过程，下面将具有第一控制器1741的爬行垫10命名为第一爬行垫101，将具有第二控制器1742的多块爬行垫10命名为第二爬行垫102、第三爬行垫103、第四爬行垫104、……、第n爬行垫10n，n为不小于2的整数。第一爬行垫101的每个接头件161有一路I/O，一路CAN网络，每个接头件161的CAN网络都连通。
那么，在热插拔分配ID的情形下，有：
第一爬行垫101的四个接头件161的I/O都设置为浮空输入模式，默认为高电平；第二爬行垫102与第一爬行垫101连接，第二爬行垫102上电会将其接头 件161的I/O设置为低电平；第一控制器1741检测到第二爬行垫102的I/O被拉低，第一控制器1741得到第二爬行垫102的位置，并通过CAN网络将第一个ID分配给第二爬行垫102，第二爬行垫102收到第一个ID后，进入ID锁定模式，并返还应答给第一控制器1741；第二爬行垫102进入ID锁定模式后，会把其上的其余三个接头件161的I/O设置为浮空输入模式，默认为高电平。当第三爬行垫103与第二爬行垫102拼接时，第二爬行垫102通过CAN网络告知第一控制器1741，第二爬行垫102上的一个接头件161被接入了第三爬行垫103，第一控制器1741会分配第二个ID给第三爬行垫103。第三爬行垫103收到第二个ID后，进入ID锁定模式，并返还应答给第一控制器1741；第三爬行垫103进入ID锁定模式后，会把其上的其余三个接头件161的I/O设置为浮空输入模式，默认为高电平。以此类推，直至第n爬行垫10n接入，从而完成所有的ID分配和位置锁定。
在断电拼接后上电动态分配ID的情形下，有：
所有相互拼接的爬行垫10上电后4个I/O默认为浮空输入模式，读到的电平为高电平。同一爬行垫10中，会按照四个接头件161轮询的方式确认是否被接入其他爬行垫10，具体的识别流程为：
第一爬行垫101的四个接头件161的I/O分别轮流设为低电平输出，第二爬行垫102检测到接头件161的电平被拉低后，进入ID分配模式，并通过CAN网络广播自己已经进入了ID分配模式。第一控制器1741接收到广播消息后分配第一个ID给第二爬行垫102，当第二爬行垫102接收到ID设置命令后会返还应答。第一控制器1741接收到应答后，命令第二爬行垫102进入模块接入模式。第二爬行垫102会先设置其中一个接头件161的I/O为低电平输出，第三爬行垫103检测到接头件161的电平被拉低后进入ID分配模式，并广播自己已经进入ID分配模式。第二爬行垫102收到第三爬行垫103进入ID分配模式的消息后通过CAN告知第一控制器1741，即：第二爬行垫102的接头件161接入了第三爬行垫103，请求分配ID。第一控制器1741会分配第二个ID给到第三爬行垫103。第三爬行垫103得到ID后通过CAN广播自己进入了ID锁定模式。第二爬行垫102会继续拉低自身接头件161的I/O去判断接头件161是否有接入其他爬行垫10。以此类推，在第二爬行垫102轮询完后，会通过CAN广播自己已经退出其 他爬行垫10接入模式。第一控制器1741会命令第三爬行垫103进入其他爬行垫10接入模式，第三爬行垫103轮询是否有接入其他爬行垫10。以此类推，直至第n爬行垫10n接入，从而完成所有的ID分配和位置锁定。
由于每块爬行垫10都包括压力传感层12和发光元件层14，其中压力传感层12作为输入模块，压力传感层12包括压电薄膜传感器阵列(图中未标示)，薄膜压力传感器阵列呈多行多列分布在弹性层13与支撑板111之间，形成多行多列的扫描点，每个扫描点的数据均由第二电路板172将采集到的当前电压输入至第一电路板171后，再由控制器174转换而来，与此同时，第一电路板171将接收到的数据通过CAN网络上传至第一控制器1741。
请参阅图15和图11，为了实现较高的扫描刷新率，采取矩阵式扫描方法采集压力传感层12的数据，具体是把一块爬行垫10上的压力传感层12细分为第一区域、第二区域、第三区域及第四区域，如每个区域中压力传感层12的压电薄膜传感阵列为五行五列。每个区域共用一个ADC采样口，第二电路板172上设有多个行译码器1721和多个列译码器1722；每个区域的行的通断由行译码器1721进行控制，列的通断由列译码器1722进行控制。一块爬行垫10上所有区域共包括四块行译码器1721和四块列译码器1722，从而实现对压力传感层12采集的控制，且四块行译码器1721的控制I/O连接在一起为四路共通I/O，四块列译码器1722的控制I/O连接在一起为四路共通I/O。由于控制器174的引脚较少，控制组件17还包括存储器175，8个I/O由控制器174通过存储器175(如74HC595)扩展I/O后进行驱动。以上可通过四路ADC和四路普通I/O解决的压力传感层12的数据采集，且扫描刷新率达到100Hz以上。
发光元件层14则作为输出模块，由多块LED灯板成多行多列(如十行十列)组成共多个像素点，每个像素由白、红、绿、蓝组成，可产生超过1000万的颜色。每个LED灯板通过LED恒流驱动芯片恒电流驱动，第一控制器1741(或第二控制器1742)可通过CAN网络下发指令控制每一个LED灯板的颜色和亮度。
具体地，为了实现可单独控制每一块LED灯板的亮度，本申请采取矩阵式扫描的方法驱动LED灯板，接线采取共阳的方法。横轴为多排，LED恒流驱动芯片对LED灯板的阴极的通断进行控制，每片LED恒流驱动芯片有40路通道。 该LED恒流驱动芯片采用集成电路总线(Inter-Integrated Circuit，简称IIC)与同一爬行垫10中的控制器174通信，可通过LED恒流驱动芯片的地址管脚接高低电平实现一路IIC挂载两片LED恒流驱动芯片。LED灯板亮度调节可达到255级。竖轴为多列(列的数量与排的数量相同)共阳接口，控制器174通过存储器175扩展I/O后驱动由三极管组成的开关和放大电路，对LED灯板的阳极的通断进行控制。通过矩阵式扫描可实现单独控制任意一个LED灯板的通断，多个LED灯板点亮的情况下也能保证至少24Hz以上的刷新，确保人眼觉察不到闪烁。
若仅仅有发光元件层14显示，则有：当多块爬行垫10进行拼接并通过拼接识别并分配ID后，第一控制器1741通过CAN网络可得到所有爬行垫10的位置和ID，得到朴括结构后，可通过WIFI、蓝牙等自动更新到对应的PC上位机或手机APP。手机APP或者PC上位机可随意编辑现有结构的每一个LED灯板的颜色和亮度，也可导入特定模式的照片或者图案，选择部分或全部图案推送到第一控制器1741，第一控制器1741可通过CAN网络控制其他爬行垫10的第一控制器1741，显示出对应的图案。
若仅仅有压力传感层12输入，则有：扫描频率≥100Hz，多块爬行垫10进行拼接并通过拼接识别并分配ID后，第一控制器1741通过CAN网络可得到所有爬行垫10的位置和ID。第一控制器1741会根据当前结构生成虚拟地图，地图每个像素由x坐标、y坐标和压力数据组成。可通过采集到的数据填充到地图，可分析得到婴幼儿的重量，大小，运动路径。也可通过持续的采集数据分析婴幼儿的重量、运动习惯等。
若发光元件层14和压力传感层12同时工作，则有：除开可实现上述内容外，还可实现游戏互动、主动路径导向等。即通过特定的图案或者光效引导婴幼儿的运行方向，通过判断婴幼儿是否踩踏光效的位置去决定下一步输出的图案和光效，从而可以实现婴幼儿的爬行指引。
综合上述，本申请实施例提供的爬行垫10可以实现多个拼接以供婴幼儿爬行，使得婴幼儿具有更大的爬行空间。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
