本发明目的的实现、 功能特点及优点将结合实施例, 参照附图做进一步说明。 具体实施方式 应当理解,此处所描述的具体实施例仅仅用以解释本发明, 并不用于限定本发明。 参照图 1, 图 1为本发明的移动终端防摔方法的第一实施例流程示意图, 该方法 包括:
510、检测移动终端是否处于有损跌落状态, 若该移动终端处于有损跌落状态, 则 执行步骤 S20。 该移动终端包括智能手机、 平板电脑等。 在该步骤 S10中, 检测移动终端是否处于有损跌落状态, 当该移动终端处于有损 跌落状态时, 需要对该移动终端的下落姿势进行调整, 当该移动终端并不是处于有损 跌落状态时, 则不需要对该移动终端的下落姿势进行调整。 具体的, 该步骤 S10包括 (如图 2所示):
511、 检测该移动终端在预设方向的速度值; 该预设方向为竖直方向。 在该步骤 S11中, 检测移动终端在竖直方向的速度值。 可利用速度传感器检测移 动终端在竖直方向的速度值。 在移动终端跌落过程中, 不管是垂直跌落还是呈抛物线 轨迹跌落, 都存在竖直方向的速度值。
512、判断该移动终端在预设方向的速度值是否大于预设速度阈值,若该移动终端 在预设方向的速度值大于预设速度阈值, 则确定该移动终端处于有损跌落状态。 该预设速度阈值可预先设置。 该预设速度阈值的设定基于不同移动终端所具有的 抗摔能力而定。 具体的, 预先对移动终端进行跌落试验以找出移动终端在各个姿势落
地而出现有损坏时的竖直方向上的最小速度值, 将该最小速度值作为预设速度阈值。 因此, 在实际使用过程中, 当移动终端在竖直方向的速度值超过该预设速度阈值时, 则认为该移动终端处于有损跌落状态。
S20、 检测基于该移动终端预设端面上的预设点的竖直线与该预设端面的夹角 a, 或者, 检测基于该移动终端上的预设点的竖直线与该预设端面所在平面的夹角 a。 在该步骤 S20中, 可检测基于该移动终端预设端面上的预设点的竖直线与该预设 端面的夹角 α, 该移动终端预设端面可以为移动终端的上端面、 下底面、 左侧面、 右 侧面、 正面或背面, 该预设点可以为预设端面上的几何中心, 也可以为预设端面上的 任意一个点。 如图 3所示, 为移动终端在跌落过程中的侧视图 (正对我们的一面为移 动终端的左侧面), 预设端面为移动终端的上端面 F, 预设点为上端面 F上的几何中心 P。 在该步骤 S20中, 也可检测基于该移动终端上的预设点的竖直线与该预设端面所 在平面的夹角 α, 该预设点可在移动终端的任意端面, 如该预设点可在移动终端的上 端面、 下底面、 左侧面、 右侧面、 正面或背面。 S30、根据检测的该夹角 a与预设防摔夹角 β, 分析是否需要对该移动终端进行姿 势调整, 若需要对该移动终端进行姿势调整, 则执行步骤 S40。 该预设防摔夹角 β可预先设置。 具体的, 预先对移动终端进行跌落试验以找出该 移动终端最抗摔的落地姿势, 记录预设点的竖直线与预设端面的夹角作为预设防摔夹 角 。 在该步骤 S30中, 根据检测的该夹角 α与预设防摔夹角 β, 分析是否需要对该移 动终端进行姿势调整, 具体的, 该步骤 S30包括: 判断检测的该夹角 α与预设防摔夹 角 β的差值是否小于等于预设值, 若该夹角 a与该预设防摔夹角 β的差值大于该预设 值, 则确定需要对该移动终端进行姿势调整。 该预设值可根据实际需要设置, 如可设置为 2°。 当检测的该夹角 α与预设防摔夹 角 β的差值小于等于预设值, 如检测的该夹角 a与预设防摔夹角 β的差值小于等于 2° (包括夹角 α减去预设防摔夹角 β的差值小于等于 2°, 也包括预设防摔夹角 β与夹角 α的差值小于等于 2°), 则不需要对移动终端进行姿势调整。 当检测的该夹角 α与预设 防摔夹角 β的差值大于预设值, 如检测的该夹角 α与预设防摔夹角 β的差值大于 2°, 则需要对移动终端进行姿势调整。
S40、 根据检测的该夹角(X与预设防摔夹角 β的差值, 控制动能模块对该移动终 端的下落姿势进行调整。 该动能模块包括带有摆钟的马达、 陀螺仪或活塞等。 在该步骤 S40中, 根据检测 的该夹角 α与预设防摔夹角 β的差值,控制动能模块对移动终端的下落姿势进行调整。 该动能模块将电能转换为动能, 带动整个移动终端转动, 从而实现对移动终端下落姿 势的调整。 由于移动终端跌落是一个动态的过程, 因此可根据预设时间间隔反复执行步骤 S 10 到 S40, 对移动终端的下落姿势进行调整, 将冲击调整至最坚固部份, 从而保护 脆弱部份, 改善移动终端的防摔性能。 采用本发明实施例, 在移动终端处于有损跌落状态时, 根据检测的该夹角 α与预 设防摔夹角 β的差值, 控制动能模块对该移动终端的下落姿势进行调整。 通过调整移 动终端的下落姿势规避易损部位的撞击, 从而改善移动终端的防摔性能。
参照图 4, 图 4为图 1中步骤 S40的第一实施例流程示意图, 该步骤 S40包括: Α、 根据预设的调整幅度控制动能模块调整该移动终端的下落姿势, 以将该移动 终端的该夹角 α朝着接近该预设防摔夹角 β的方向调整。 根据预设的调整幅度控制动能模块调整该移动终端的下落姿势, 如预设的调整幅 度为 3°, 在该步骤中, 按照每次调整移动终端角度变化 3°的调整幅度对动能模块进行 控制, 设置该动能模块的电压、 电流和使能时间, 通过该动能模块对移动终端的下落 姿势进行调整。
Β、检测姿势调整后的该夹角 α, 并判断调整后的该夹角 α与预设防摔夹角 β的差 值是否小于等于预设值, 若调整后的该夹角 α与预设防摔夹角 β的差值大于预设值, 则返回步骤 Α, 直到调整后的该夹角 a与预设防摔夹角 β的差值小于等于预设值。 在该步骤中, 判断步骤 Α调整后的移动终端的夹角 α与预设防摔夹角 β的差值是 否小于等于预设值, 以确定是否需要继续执行步骤 Α进行循环调整, 使得移动终端最 后以最佳下落姿势跌落。
参照图 5, 图 5为图 1中步骤 S40的第二实施例流程示意图, 该步骤 S40包括:
D、 根据检测的该夹角(X与预设防摔夹角 β的差值计算调整所需电压、 电流和使 能时间。 在该步骤中, 根据检测的该夹角 α与预设防摔夹角 β的差值计算调整所需电压、 电流和使能时间。 具体的, 也可考虑动能模块在移动终端内所处的位置, 根据该动能 模块在移动终端内所处的位置及检测的该夹角 α与预设防摔夹角 β的差值计算调整所 需的电压、 电流和使能时间。
Ε、 控制该动能模块根据计算出的电压、 电流和使能时间启动并运转, 对移动终 端的下落姿势进行调整。 该动能模块将电能转换为动能, 带动整个移动终端转动, 从而实现对移动终端下 落姿势的调整。
