请参考图1和图2,本申请实施方式提供的一种电子取景器110,包括壳体1101和调节机构1111。壳体1101内设有镜头1103。镜头1103包括镜片1105。调节机构1111连接壳体1101。调节结构1111包括第一拨轮1113、第二拨轮1115和传动机构1117。传动机构1117连接第一拨轮1113和第二拨轮1115。第二拨轮1115连接镜片1105。第二拨轮1115转动时带动镜片1105沿镜头1103的光轴L移动。传动机构1117用于使第一拨轮1113的转动转换为第二拨轮1115的转动,进而带动镜片1105沿镜头1103的光轴L移动以调节电子取景器110的屈光度。在一实施例中,所述第一波轮1113的旋转面垂直于所述第二波轮1115的旋转面。
示例性地,所述传动机构1117用于将所述第一波轮1113的转动转换成直线运动,同时将所述直线运动转换成所述第二波轮1115的转动。所述第二波轮1115的转动可以转换成沿光轴的移动。
示例性的,所述第一波轮1113位于所述壳体1101的外部,所述第二波轮1115位于所述壳体1101的内部。
上述电子取景器110,通过传动机构1117将第一拨轮1113的转动转换为第二拨轮1115的转动,进而带动镜片1105沿镜头1103的光轴L移动以调节电子取景器110的屈光度,这样,能够实现屈光度调节的电子取景器110可适应不同用户的需求。
具体地,在图1和图2所示的实施方式中,通过拨动第一拨轮1113进行转动,使得调 节机构1111能够沿第一拨轮1113的轴向方向M进行来回地移动。在这种情况下,第二拨轮1115可随着调节机构1111的移动而相应地转动,从而使得镜片1105沿光轴L来回地移动。第一拨轮1113可为露在电子取景器110外部的部件,用户可通过转动第一拨轮1113来驱动第二拨轮1115转动,进而带动镜头1103移动来调节电子取景器110的屈光度。在图2中,镜头1103内设有4个镜片1105,构成镜片组。在其它实施方式中,镜头1103内的镜片1105数量还可以其它数量,例如是1个,2个,3个或多于4个,在此不作具体限定。
在本申请实施方式中,请再结合图1,壳体1101前侧连接有观察部1102,观察部1102开设有观察窗1104。镜头1103可以自观察窗1104处向前伸出。第一拨轮1113的一部分从观察部1102的侧壁露出,第一拨轮1113的另一部分位于观察部1102内,这样可方便供用户进行操作,也可对位于观察部1102内的第一拨轮1113的部分进行保护。壳体1101前侧是指在用户通过电子取景器110观察时,朝向用户的一侧。
可以理解,在其它实施方式,第一拨轮1113也可整体地从观察部1102露出,这样可方便用户从不同方位操作第一拨轮1113。
请参考图3至图6,在某些实施方式中,传动机构1117包括转轴1121和套筒1123。转轴1121包括第一端1125和第二端1127。第一端1125固定连接第一拨轮1113。套筒1123套设第二端1115。套筒1123设有驱动臂1129。驱动臂1129连接第二拨轮1115。第一拨轮1113沿第一方向转动时带动转轴1121转动,进而带动套筒1123沿平行于镜头1103光轴L移动。套筒1123沿平行于镜头1103光轴L移动时带动驱动臂1129拨动第二拨轮1115沿第二方向转动。如此,可简单实现通过第一拨轮1113间接地控制镜片1105进行移动。
具体地,在图3和图4所示的实施方式中,将第一拨轮1113沿第一方向转动的情况下,套筒1123可被带动地沿远离第一拨轮1113的方向移动。在这种情况下,第二拨轮1115会被驱动臂1129带动地沿第二方向转动。
可以理解,通过将第一拨轮1113的转动转换为转轴1121和套筒1123的直线移动,进而再转换为第二拨轮1115的圆周运动,可简化结构,易于操作。
请参考图6和图7,在某些实施方式中,第二拨轮1115的外周面设有拨动块1131。驱动臂1129的末端设有挡块1133。挡块1133用于抵接在拨动块1131的一侧。套筒1123沿平行于镜头1103光轴L移动时带动挡块1133驱动拨动块1131转动,进而带动第二拨轮1115沿第二方向转动。如此,可简单实现套筒1123带动第二拨轮1115进行转动。
具体地,在套筒1123沿远离第一拨轮1113的方向移动的情况下,挡块1133抵接在拨动块1131的一侧,使得挡块1133带动拨动块1131移动,拨动块1131将会沿第二拨轮1115 的轴向方向转动,从而带动第二拨轮1115进行转动。
在某些实施方式中,第二拨轮1115连接有第一弹性件(图未示)。第一弹性件用于在第一拨轮1113沿第三方向转动时驱动第二拨轮1115沿第四方向转动。第一方向与第三方向相反。第二方向与第四方向相反。如此,第二拨轮1115可具有复位功能。
具体地,在第二拨轮1115沿第二方向转动的情况下,可对第一弹性件进行压缩而产生弹力。在第一拨轮1113沿第三方向(即与第一方向相反的方向)转动时,第一弹性件通过回复力带动第二拨轮1115沿第四方向(即与第二方向相反的方向)转动,使得在第一拨轮1113进行来回转动的情况下,镜片1105可以沿光轴L进行来回移动。在一个实施方式中,第一弹性件的一端连接至壳体1101,另一端连接至拨动块1131或第二拨轮1115。
另外,第一弹性件可包括扭簧、卷簧、弹片或弹簧。在其它实施方式,也可以省略第一弹性件,具体地,驱动臂1129上的挡块1133可直接套设在拨动块1131,由第一拨轮1113沿第一方向和第三方向来回转动时,可带动第二拨轮1115沿第二方向和第四方向来回转动。在这样的实施方式中,可以是转轴1121与套筒1123螺纹连接,也可以是在套筒1123的一侧增加另一弹性件,用于驱动套筒1123向靠近第一拨轮1113的方向移动。
请参考图4至图6,在某些实施方式中,电子取景器110包括螺旋面1137和抵持块1139。螺旋面1137设在第二端1127外周面和套筒1123内的其中一个,抵持块1139设在第二端1127外周面和套筒1123内的另一个。螺旋面1137与抵持块1139配合连接,以使转轴的转动转换为套筒1123沿平行于镜头1103光轴L的移动。如此,可简单实现将第一拨轮1113的转动置换为套筒1123沿平行于镜头1103光轴L的直线运动。
具体地,在图示的实施方式中,螺旋面1137设在第二端1127的外周面,抵持块1139设在套筒1123内。螺旋面1137在第二端1127的外周面上整体沿转轴1121的轴线方向延伸。抵持块1139凸设在套筒1123的内壁表面。在套筒1123套设转轴1121的第二端1127的情况下,套筒1123内的抵持块1139抵接在螺旋面1137的表面。在第一拨轮1113带动转轴1121沿转轴1121的轴线方向转动的情况下,可带动抵持块1139沿螺旋面1137的表面进行相对移动,最终使得套筒1123可沿平行于镜头1103的光轴L移动。
另外,可以理解,在其它的实施方式中,螺旋面1137可设在套筒1123内,抵持块1139可设在第二端1127的外周面。具体原理和上述实施方式的原理类似,在此不再赘述。
请参考图4、图6和图8,在某些实施方式中,套筒1123设有导向孔1141。传动机构1117包括第一导向柱1143。第一导向柱1143的长度方向平行于镜头1103光轴L。套筒1123通过导向孔1141滑动地安装在第一导向柱1143。如此,可保证套筒1123沿轴线M的方向 进行平稳移动。
具体地,轴线M平行于镜头1103光轴L。可以理解,套筒1123在沿轴线M进行移动的情况下可能会发生晃动,从而使得套筒1123难以平稳移动而可能偏离原先的移动方向,影响传动机构1117带动第二拨轮1115的移动效果。通过设置导向孔1141和第一导向柱1143,可对套筒1123的移动进行导向,在套筒1123进行移动时可增加套筒1123的平稳性。在一个实施方式中,导向孔1141的内壁和第一导向柱1143的外表面为光滑面,使得套筒1123沿第一导向柱1143移动时可较为省力。
请参考图3至图5,在某些实施方式中,转轴1121外周面设有环状的段感部1145。段感部1145沿转轴1121的周向设有多个凹槽1147。壳体1101上固定有弹片1149。弹片1149的末端收容在其中一个凹槽1147。在转轴1121转动时,弹片1149的末端切换收容至不同的凹槽1147。如此,可使得转轴1121保持在特定的位置,也可以为用户提供转动时的段感,提升了用户体验。
具体地,在弹片1149的末端收容在转轴1121的其中一个凹槽1147的情况下,弹片1149可卡设在该凹槽1147内,使得转轴1121被限定地保持在当前位置。由于转轴1121的位置是固定的,则套筒1123的位置也会是固定的。这样,第二拨轮1115可转动并保持在特定的位置。在进一步地转动第一拨轮1113的情况下,则弹片1149的末端会由于自身弹性而被挤出当前的凹槽1147,并可收容在相邻的一个凹槽1147内,即,第一拨轮1113转动时方便对镜片1105从当前位置调整并保持在另一位置。
请参考图1和图8,在某些实施方式中,传动机构1117包括第一连接件1151,第一连接件1151连接第一拨轮1113和第一端1125。如此,可方便对元件的空间位置进行调整。
具体地,在图1所示的实施方式中,第一拨轮1113部分地位于壳体1101的外部,转轴1121位于壳体1101内。可以理解,通过设置第一连接件1151,可对第一拨轮1113在壳体1101上的位置进行调整,避免第一拨轮1113和转轴1121相距过近而不方便装配。另外,由于第一拨轮1113是部分地外露在外,也经常接触用户,因此,在某些实施方式中,第一拨轮1113通常采用金属制成,而转轴1121和第一连接件1151位于电子取景器110内部,通常由塑料制成,通过第一连接件1151的转换可以将第一拨轮1113与转轴1121进行连接。具体地,在一个实施方式中,第一连接件1151的两侧分别设有第一连接块(图未示)和第二连接块(图未示),第一连接块与第一拨轮1113可通过过盈配合、焊接、粘接等方式固定连接,第二连接块与转轴1121的第一端1125可通过过盈配合、焊接、粘接等方式固定连接。转轴1121可以是一体成型结构,第一连接件1151也可以是一体成型结构,套筒1123也可 以是一体成型结构。
请参考图3、图4和图8,在某些实施方式中,第一端1125设有第一支撑柱1153。第二端1127设有第二支撑柱1155。电子取景器110包括安装在壳体1101上的第一固定板1157和第二固定板1159。第一支撑柱1153转动地穿设第一固定板1157。第二支撑柱1155转动地穿设第二固定板1159。如此,可使得转轴1121进行平稳地转动。
可以理解,通过第一支撑柱1153转动穿设第一固定板1157,以及第二支撑柱1155转动穿设第二固定板1159,可使得转轴1121能够沿轴线M进行平稳转动,避免发生晃动。在这样的实施方式中,第一连接件1151固定连接第一支撑柱1153。
请参考图8,在某些实施方式中,第一固定板1157上设有第一限位块1161。转轴1121外周面设有第二限位块1163。第一限位块1161和第二限位块1163用于在接触的情况下限制转轴1121的转动角度。如此,可避免转轴1121由于转动过度使得元件之间进行发生挤压。
具体地,在第一限位块1161与第二限位块1163接触的情况下,转轴1121被第一限位块1161阻挡而无法继续转动,这样可提示用户,第一拨轮1113沿第一方向或第三方向已转动至极限位置,可避免转轴1121由于转动过度使得元件之间相互挤压的情况。
请参考图2和图7,在某些实施方式中,第二拨轮1115连接有第二连接件1165。镜头1103包括位于壳体1101内的镜筒1167。镜片1103位于镜筒1167中。第二拨轮1115转动时带动第二连接件1165驱动镜筒1167沿镜头1103光轴L沿第五方向移动。如此,通过镜筒1167的整体移动来驱动镜片1103的移动,简单易行。
具体地,第二拨轮1115的底部凸设有一环状部1114,环状部1114开设有一缺口1116,第二连接件1165的顶部设有一凸出部1118,凸出部1118部分地位于缺口1116中,这样,在第二拨轮1115转动时,可带动环状部1114转动,缺口1116的侧壁可抵在凸出部1118上进而可带动第二连接件1165转动。另外,可通过螺钉将第二拨轮1115和第二连接件1165进行锁定,防止第二拨轮1115和第二连接件1165之间发生分离。在图示的实施方式中,第二拨轮1115的转动方向与第二连接件1165的转动方向一致。
请结合图7,第二连接件1165的外周面凸设有推块1119,镜筒1167的外表面设有凸块1120,推块1119抵在凸块1120的一侧,在第二连接件1165转动的情况下,推块1119可推动凸块1120沿转动方向移动,进而带动镜筒1167沿第五方向移动。
请再结合图2,在图示的实施方式中,镜筒1167内设有4个镜片1105。4个镜片1105固定在镜筒1167内,镜筒1167可移动地位于壳体1101内,第二连接件1165可收容在壳体1101开设的通孔(图未示)内,通过第二连接件1165,将壳体1101外的第二拨轮1115和 壳体1101内的镜筒1167进行连接,一方面,方便第二拨轮1115的维护,另一方面,也便于元件之间的装配。
请参考图7,在某些实施方式中,镜筒1167外表面设有固定件1169。电子取景器110包括第二弹性件1171。第二弹性件1171抵接在壳体1101内壁和固定件1169之间。第二弹性件1171用于驱动镜筒1167沿第六方向移动。第六方向与第五方向相反。如此,可通过第二弹性件1171对镜筒1167进行另一方向的移动。
具体地,第五方向和第六方向均沿镜头1103的光轴L,或平行于镜头1103的光轴L,请结合图8,在第一拨轮1113沿第一方向转动时,镜筒1167沿镜头1103光轴L在第五方向移动的情况下,可对第二弹性件1171进行压缩而使第二弹性件1171产生回复力。在需要镜筒1167沿第六方向移动时,第一拨轮1113沿第三方向转动,第二弹性件1171通过回复力驱动镜筒1167沿第六方向(即与第五方向相反的方向)移动,使得镜片1105可以沿光轴L进行来回移动。
第二弹性件1171可包括扭簧、卷簧、弹片或弹簧,在图示的实施方式中,第二弹性件1171为弹簧。在其它实施方式,也可以省略第二弹性件1171,第二连接件1165的推块1119可直接套设凸块1120上,由第一拨轮1113沿第一方向和第三方向来回转动时,带动第二拨轮1115沿第二方向和第四方向来回转动,进而带动镜筒1167沿第五方向和第六方向来回移动。当然,在这样的实施方式中,也可以设置第二弹性件1171来增加驱动力。
请参考图7,在某些实施方式中,电子取景器110包括第二导向柱1173。第二导向柱1173连接在壳体1101内。第二导向柱1173穿设第二弹性件1171和固定件1169。如此,可对第二弹性件1171的伸缩方向进行导向。
可以理解,镜筒1167沿镜头1103光轴L进行来回移动的情况下,第二弹性件1171会产生平行于光轴L方向的弹力。通过设置第二导向柱1173,可使得产生的弹力不会发生偏移而使得第二弹性件1171发生偏离,保证第二弹性件1171能够稳定地对镜筒1167进行驱动。
在某些实施方式中,电子取景器110还包括显示屏1175,显示屏1175位于镜头1103的物侧。如此,可以通过镜头1103观察到显示屏1175所显示的景象,同时,通过移动镜片1105以调节电子取景器110的屈光度,以使不同用户也能透过电子取景器110清楚地观察到显示屏1175所显示的景象。
具体地,显示屏1175可通过柔性电路板与拍摄装置连接,拍摄装置包括图像传感器,图像传感器所形成的图像数据经柔性电路板传输至显示屏1175进行显示。
请参考图14,本申请实施方式提供的一种拍摄装置1000,包括机身200和上述任一实施方式的电子取景器110。电子取景器110安装在机身200。
上述拍摄装置1000,通过传动机构1117将第一拨轮1113的转动转换为第二拨轮1115的转动,进而带动镜片1105沿镜头1103的光轴L移动以调节电子取景器110的屈光度,这样,能够实现屈光度调节的电子取景器110可适应不同用户的需求。
具体地,在通过电子取景器110对拍摄装置1000拍摄到的图像进行取景时,可通过来回转动第一拨轮1113,在第二拨轮1115和传动机构1117的配合下,可对位于壳体1101内的镜片1105所在的位置进行调整,使得镜片1105沿光轴L方向来回移动,从而达到改变屈光度的效果。
在图示的实施方式中,拍摄装置1000为相机。在其它实施方式中,拍摄装置1000可为摄像机或其它具备拍摄功能的装置。
请参阅图9至图12,本申请实施方式提供一种调节装置100,调节装置100包括弹性件10、支架20、至少两个抵持件30和拨动件40。弹性件10包括至少两个第一抵持部11。支架20包括支撑件21,弹性件10设置于支撑件21。
抵持件30与第一抵持部11一一对应设置,抵持件30分别抵靠对应的第一抵持部11。拨动件40能够转动地设置于支架20,弹性件10通过至少两个抵持件30抵持拨动件40,使得拨动件40相对于支架20转动预设角度后被抵持件30定位,至少两个抵持件30沿拨动件40的周向均匀间隔分布。
上述调节装置100中,弹性件10能够通过抵持件30向拨动件40提供抵持力,使得拨动件40不管在转动过程中还是静止状态均能保持稳定,这样可避免拨动件40出现晃动而影响调节装置100的正常使用。
具体地,在图示的实施方式中,拨动件40整体呈一圆环形,弹性件10通过抵持件提供的抵持力为沿拨动件40径向的作用力。
至少两个抵持件30沿拨动件40的周向均匀间隔分布,一方面,拨动件40处于静止状态时,弹性件10通过至少两个抵持件30抵持拨动件40,向拨动件40提供抵持件30所在的径向作用力,避免拨动件40的晃动。另一方面,在拨动件40被拨动的情况下,驱动力可克服拨动件40的静摩擦力而使拨动件40转动,在转动过程中,弹性件10通过抵持件30始终向拨动件40提供径向作用力,避免拨动件40的晃动。拨动件40相对于支架20转动预设角度后,也就是说,拨动件40停止转动后,拨动件40被抵持件30定位。
上述驱动力可以是用户直接施加于拨动件40上的作用力,也可以是电驱动件通电时施 加于拨动件40上的作用力,在此不作具体限定。预设角度可以通过调节装置100的卡位结构实现,也可通过对电驱动件的通电时间等电参数来控制,也可通过支架20上的角度刻度来提醒用户转动了多少角度来实现等。
本申请实施方式的调节装置100可以安装在电子设备,用于在电子设备中调节电子设备的功能或者与功能相关的参数,或进行功能、参数的选择。在一个例子中,本申请实施方式的调节装置100可以安装于相机,用户在使用相机时,可以拨动拨动件40转动,拨动件40的转动角度可以转换为相机的用户界面的参数调节或参数选择。
另外,在图示的实施方式中,弹性件10包括弹簧。在其它实施方式中,弹性件可以包括弹片或者其它可以通过弹性形变提供弹力的部件。弹性件10的数量可以一个或至少两个。可以理解,当弹性件10的数量为一个时,弹性件10的两端抵靠抵持件30,弹性件10两端之间的部位可连接支撑件21,以向弹性件10提供支撑。
支架20可以由塑料或者金属制成。在本申请实施方式中,支架20采用塑料通过注塑工艺注塑成型。拨动件40可以由塑料或者金属制成。在本申请实施方式中,采用金属(如铝合金)来制成拨动件40。
抵持件30可以呈球状、方块状或者其它规则形状或不规则形状等。在本申请实施方式中,抵持件30呈球状,第一抵持部11通过呈球状的抵持件30抵持拨动件40,这样拨动件40转动时的阻力较小。
请参阅图10至图12,在某些实施方式中,弹性件10的数量是至少两个,至少两个弹性件10沿支撑件21的周向均匀间隔设置。
如此,当至少两个弹性件10沿支撑件21的周向均匀间隔地设置时,沿拨动件40同一径向的两个弹性件10所提供的抵持力的方向相反,有利于提高拨动件40在转动或者静止状态的稳定性,能有效减少拨动件40的晃动。
具体地,弹性件10的数量可以是两个、三个、四个或四个以上等。在图示的实施方式中,弹性件10的数量是两个,两个弹性件10沿支撑件21的周向间隔180度角设置。当弹性件10的数量为三个时,三个弹性件10沿支撑件21的周向间隔120度角设置;当弹性件10的数量为四个时,四个弹性件10沿支撑件21的周向间隔90度角设置。也就是说,当弹性件10的数量是N个时(N为自然数且N>1),相邻两个弹性件10相隔的角度是360/N。均匀间隔设置的至少两个弹性件10有利于向拨动件40在拨动件40径向上提供分布均匀的作用力。
请参阅图10和图11,在某些实施方式中,支撑件21设置有与弹性件10一一对应的容 纳腔211,弹性件10收容于容纳腔211。
如此,弹性件10收容于容纳腔211,容纳腔211可以为弹性件10的形变方向提供导向作用,即可以使弹性件10沿拨动件40的径向形变,以使弹性件10能够正确地提供沿拨动件40径向的抵持力。
具体地,容纳腔211可以是支撑件21上开设的圆孔、方孔或其它形状的孔。当弹性件10的数量为一个时,容纳腔211可为一个通孔,一个弹性件10收容于容纳腔211并可固定于容纳腔211中,该弹性件的两端可为作两个第一抵持部11,抵持在支撑件21且位于弹性件10两端之间的部位可为作第二抵持部12。当弹性件10的数量为至少两个时,与弹性件10数量一一对应的容纳腔211可为盲孔,弹性件10的一端可抵靠在盲孔的底部,一端抵靠抵持件30,抵靠抵持件30的一端作为第一抵持部11。弹性件10抵靠支撑件21的一端可作为第二抵持部12。
请参阅图11和图12,在某些实施方式中,弹性件10为两个,两个弹性件10沿一直线L排列设置,且第一抵持部11分别位于弹性件10远离其他弹性件10的一端。如此,两个弹性件10能够在相反方向上分别抵持一个抵持部,即两个弹性件10产生的抵持力处于同一直线L上。具体地,直线L可沿拨动件40的径向设置。
请参阅图11,在某些实施方式中,弹性件10还包括第二抵持部12,两个第二抵持部12分别抵靠支撑件21,抵持件30分别抵靠对应的弹性件10的第一抵持部11。如此,支撑件21能够为弹性件10提供支点,使弹性件10能够在抵靠抵持件30后为抵持件30提供抵持力。
请参阅图11和图12,在某些实施方式中,两个弹性件10向拨动件40提供的抵持力F1和F2大小相等、方向相反。如此,拨动件40受到两个大小相等方向相反的抵持力F1和F2,能提高拨动件40的稳定程度,进一步减少拨动件40的晃动。
在某些实施方式中,至少两个弹性件10向拨动件40提供的抵持力大小均相等。如此,拨动件40可以受到沿支撑件21周向均匀分布的大小均等的抵持力,拨动件40在保持稳定性的前提下,在被拨动时可以顺畅地转动。
在某些实施方式中,至少两个弹性件10的弹性模量均相同,或均不相同,或部分相同和部分不相同。如此,可通过弹性模量来调整弹性件10提供的弹性力。
具体地,至少两个弹性件10的弹性模量均相同时,当弹性件10设置于调节装置100上时,每个弹性件10在相同的形变量下所提供的抵持力的大小相等。
至少两个弹性件10的弹性模量均不相同时,每个弹性件10在相同形变量下所提供的抵 持力的大小均不相同,但当弹性件10设置于调节装置100上时,沿支撑件21周向均匀布置的弹性件10可以有不同的形变量,以使每个弹性件10对拨动件40施加的抵持力大小相等,从而更好地保持拨动件40的稳定性。
至少两个弹性件10的弹性模量部分相同和部分不相同时,弹性模量相同的那部分弹性件10的形变量与弹性模量不相同的那部分弹性件10的形变量可不同,这样整体上,至少两个弹性10向拨动件40提供的抵持力也可实现相等。
请参阅图10至图12,在某些实施方式中,调节装置100包括固定在拨动件40内的转接件50,转接件50呈环状,弹性件10和抵持件30位于转接件50内所形成的空间,转接件50的内壁沿转接件50的周向开设有多个定位槽51,抵持件30分别卡合于定位槽51。
如此,当转动拨动件40时,弹性件10可以将抵持件30卡合到不同的定位槽51中,当抵持件30卡合到定位槽51中,会给拨动件40转动时提供阻力,以增加用户转动拨动件40时的段感,提升调节装置100调节功能或者参数时的精确度。
具体地,拨动件40通常由金属制成,为避免拨动件40转动时对抵持件30过多的磨损,在拨动件40和抵持件30之间增加转接件50,转接件50的材质可以为塑料。拨动件40带动转接件50转动,转接件50和抵持件30之间摩擦。进一步地,转接件50的材质可以为POM塑料,POM塑料制成的转接件50具有高硬度、高刚性和高耐磨的特性,能承受住和抵持件30之间频繁地摩擦或者碰撞而将磨损最小化。
转接件50固定于拨动件40内的方式可以是粘接、过盈配合、螺纹连接或者其他连接方式。本申请实施方式的转接件50通过粘接的方式固定于拨动件40内,粘接的连接方式简单环保,便于安装。
请参阅图12,在某些实施方式中,沿转接件50的周向,每一个定位槽51包括相对的第一侧面511和第二侧面512,第一侧面511和第二侧面512呈向定位槽51内倾斜的状态,以使得抵持件30在拨动件40转动过程中由第一侧面511或第二侧面512导引而卡入定位槽51内。
如此,倾斜的第一侧面511和第二侧面512能起到导引抵持件30落入定位槽51内的作用,还能起到减缓抵持件30落入定位槽51内的落差,以减少抵持件30和转接件50的碰撞,从而减少抵持件30和转接件50的磨损,从整体上提高调节装置100的寿命。
请参阅图12,在某些实施方式中,抵持件30呈球状,在抵持件30位于第一侧面511上时,第一侧面511与抵持件30相切,在抵持件30位于第二侧面512上时,第二侧面512与抵持件30相切。
如此,当球状的抵持件30经过第一侧面511或第二侧面512上时,可以受到较小的阻力,使抵持件30能够更顺畅地落入定位槽51内,避免出现拨动件40转动过程中,抵持件30没有落入定位槽51内而导致的虚位现象。
可以理解,当抵持件30与第一侧面511或第二侧面512有接触时,可以理解为抵持件30位于第一侧面511或第二侧面512上,抵持件30和第一侧面511或第二侧面512相切。
请参阅图12,在某些实施方式中,多个定位槽51沿转接件50的周向均匀设置在转接件50的内壁。
如此,每相邻两个定位槽51的间距是一样的,使用户在转动拨动件40时,每转动一格,抵持件30落入每个槽的间距是相同的,为用户提供均匀的段感。
请参阅图10和图11,在某些实施方式中,转接件50设有转轴52,转轴52能够转动地连接支架20。
如此,拨动件40可通过转接件50转动地连接在支架20。
具体地,转接件50通常是利用可塑性较高的材料制成,如塑料制成,而拨动件40通常是利用可塑性较低的材料制成,如金属制成。通过在转接件50设置转轴52,成本较低,工艺也相对简单。另外,转接件50固定在拨动件40上,转动拨动件40时转接件50会同时转动,转轴52也可能将拨动件40的转动角度输出,从而起到调节电子设备的功能或者参数的作用。
请参阅图10,在某些实施方式中,拨动件40的外周面形成有防滑部41,防滑部41用于增大在拨动拨动件40时的摩擦力。如此,防滑部41可以方便用户更容易的转动拨动件40,提升用户体验。
具体地,防滑部41可以是拨动件40外周面形成的凹槽,也可以是拨动件40外周面形成的凸点,还可以是在拨动件40外周面设置能够增加摩擦的部件。
请参阅图10和图11,在某些实施方式中,支架20包括连接的上支架22和下支架23,拨动件40部分地设置于上支架22和下支架23共同形成的收容空间24内。
如此,将拨动件40部分地设置于上支架22和下支架23形成的收容空间24内,能利用上支架22和下支架23的空间结构,进一步减少拨动件40的晃动,还能使拨动件40在收容空间24外的部位供用户操作。
在某些实施方式中,支撑件21可以设置于上支架22,这样,弹性件10也可设置于上支架22。在某些实施方式中,支撑件21也可以设置于下支架23,这样弹性件10也可设置于下支架23。在某些实施方式中,在有两个或以上的支撑件21时,一部分数量的支撑件21 设置于上支架22,另一部分数量的支撑件21设置于下支架23,一部分数量的弹性件10设置于上支架22,另一部分数量的弹性件10设置于下支架23。
如此,弹性件10的布置可以根据支撑件21的设置位置灵活变化。
在图11所示的实施方式中,支撑件21设置于上支架22,弹性件10对应收容在上支架22的容纳腔211中。
请参阅图10,在某些实施方式中,上支架22形成有第一定位部221,下支架23形成有第二定位部231,第一定位部221和第二定位部231配合连接以固定上支架22和下支架23的相对位置。
如此,第一定位部221和第二定位部231能固定上支架22和下支架23的相对位置,这样可以提升支架20的组装效率。
具体地,在图10所示的实施方式中,第一定位部221包括上支架22形成的两个定位孔,第二定位部231可包括下支架23形成的两个定位柱,通过定位孔和定位柱一一配合连接以固定上支架22和下支架23的相对位置。在其它实施方式中,可以是,第一定位部221可包括上支架22形成的两个定位柱,第二定位部231可包括下支架23形成的两个定位孔,还可以是,第一定位部221包括上支架22形成的一个定位柱和一个定位孔,第二定位部231可包括下支架23形成的一个定位孔和一个定位柱。在上支架22和下支架23定位安装后,可利用螺丝、卡扣等方式将上支架22和下支架23固定连接。
请参阅图9至图12,在图示的实施方式中,弹性件10的数量为两个,弹性件10是两个完全相同的弹簧。抵持件30的数量与弹性件10的数量相同,抵持件30为钢珠。支撑件21设置于上支架22,两个弹性件10分别收容于支撑件21内形成的两个容纳腔211,并且两个弹性件10沿拨动件40的径向呈一直线L设置。弹性件10的第二抵持部12抵靠在对应的一个容纳腔211的底部,第一抵持部11抵靠对应的抵持件30,对抵持件30施加抵持力使抵持件30抵靠在转接件50的内壁。因此,两个弹性件10分别为转接件50提供大小相等、方向相反的两个抵持力F1和F2,使转接件50以及和转接件50固定连接的拨动件40能够稳定地安装在调节装置100上。
当转动拨动件40时,与拨动件40固定连接的转接件50同时转动,抵持件30会落入转接件50内壁形成的定位槽51内,为拨动件40转动提供段感。在抵持件30位于第一侧面511或第二侧面512上时,抵持件30与第一侧面511或第二侧面512均相切,能使抵持件30更顺畅地落入定位槽51内,以避免抵持件30未落入定位槽51内而出现的虚位现象。
在某些实施方式中,请参阅图11,调节装置100包括角度传感器60,角度传感器60连 接拨动件40,角度传感器60用于感测拨动件40的转动角度。如此,可以将拨动件40的转动角度转换为电信号输出,对电子设备的参数进行调节或选择。
在图11所示的实施方式中,拨动件40通过转轴52连接角度传感器60。具体地,请结合图13,角度传感器60包括壳体601、电路板602、导电件603、内环部604和外环部605,转轴52的一端伸入壳体601内,导电件603固定连接转轴52,拨动件40通过转轴52连接导电件603,拨动件40转动时,通过转轴52带转导电件603转动。导电件603包括第一抵接部6031和第二抵接部6032。
内环部604和外环部605间隔地设于电路板602上,内环部604和外环部605同心设置,第一抵接部6031与内环部604抵接,第二抵接部6032与外环部605抵接。较佳地,第一抵接部6031与第二抵接部6032均具有一定的弹性,这样可增加与对应的环部的连接可靠性。
请参图13,外环部605包括间隔设置的多个导电块6051,在拨动件40转动过程中,第二抵接部6032与其中一个导电块6051抵接以使得内部环604与第二抵接部6032所抵接的导电块6051电连接。这样角度传感器60可输出一脉冲。通过拨动件40的连续转动,每当第二抵接部6032与其中一个导电块6051抵接时,角度传感器60即可输出一脉冲,脉冲的数量可对应参数的调节幅度,可以设置为一个脉冲对应于参数的一个调节幅度,例如,输出一个脉冲使得参数的数值加1或减1,也可以设置为二个脉冲对应于参数的一个调节幅度,例如,输出两个脉冲使得参数的数值加1或减1等。对于相机来说,参数可包括变焦参数、ISO参数、拍摄场景参数等等。
在某些实施方式中,内环部包括间隔设置的多个导电块,在拨动件转动过程中,第一抵接部与其中一个导电块抵接以使得外部环与第一抵接部所抵接的导电块电连接。这样也能够实现拨动件的转动角度转换为电信号输出。
在某些实施方式中,内环部和外环部均包括间隔设置的多个导电块,在拨动件转动的过程中,第一抵接部与内环部的其中一个导电块抵接,第二抵接部与外环部的其中一个导电块抵接以使得与第一抵接部所抵接的导电块和与第二抵接部所抵接的导电块电连接。这样也能够实现拨动件的转动角度转换为电信号输出。
需要指出的是,在其他实施方式中,角度传感器可包括光传感器,光传感器包括设置电路板上的发光件(如发光二极管)和光接收件(如光电二极管),通过在转轴上设置随转轴一起转动的带孔的遮光件,如格栅。发光件发射光至遮光件,通过光接收件接收到遮光件的反射光来实现电信号的输出。发光件和光接收件可以位于遮光件的同一侧,也可分别位于遮光件的相背两侧。在其它实施方式中,角度传感器可包括磁传感器,磁传感器包括设置电路 板上的霍尔传感器,通过在转轴上设置随转轴一起转动的多个磁性件,通过霍尔传感器感应靠近的磁性件来实现电信号的输出。
请参阅图14,本申请实施方式的电子设备1000包括机身200和以上任一实施方式的调节装置100,调节装置100安装在机身200。
上述电子设备1000中,可以通过弹性件10和抵持件30向拨动件40提供抵持力,使得拨动件40不管在转动过程中还是静止状态均能保持稳定,这样可避免拨动件40出现晃动而影响调节装置100的正常使用,从而保障调节装置100的调节效果。
在某些实施方式中,电子设备1000包括拍摄装置,调节装置100安装于拍摄装置的机身200上,调节装置100用于调节拍摄装置的参数或者对相机的参数进行选择。如此,装有调节装置100的拍摄装置,能够稳定且流畅地通过调节装置100调节拍摄装置的功能和参数,提升用户体验。拍摄装置也可包括上述任一实施方式的电子取景器110。拍摄装置包括相机和摄像机。
另外,电子设备1000还包括其它需要进行参数调节或选择的电子设备1000,例如遥控器等。
目前,电子器件被广泛地使用以实现相应功能,如电子器件可包括用于成像用的图像传感器,用于存储的存储器,用于信号处理的处理器等。电子器件工作时,通常会发热,如果热量不及时散发,将会对电子器件的正常工作造成不良影响。例如,高温会影响图像传感器的成像品质,也会造成图像传感器和印刷电路板之间的焊点脱落的问题,影响电子器件的正常使用。
本申请实施例提供一种散热结构,应用于图像传感器的散热,如应用于拍摄装置等的图像传感器的散热。本申请实施方式的散热结构还可以应用于存储器、处理器等部件的散热,如应用于双倍速率同步动态随机存储器(Double Data Rate SDRAM,DDR SDRAM)、数字信号处理器(Digital Signal Processing,DSP)等部件的散热。
请参阅图15-图17,本申请实施方式提供一种散热结构8100。散热结构8100包括功能组件810、第一导热层820和散热板830。功能组件810包括电子器件811和电路板812,电路板812包括相背的第一面8121和第二面8122,电子器件811设在第一面8121和第二面8122的至少一面,电子器件811包括发热器件。第一导热层820设在第二面8122,第一导热层820与第二面8122基本贴合。第一导热层820连接散热板830和电路板812,散热板830用于使经第一导热层820传导的功能组件810的热量散发。
上述散热结构8100中,功能组件810的热量可经第一导热层820传递到散热板830, 散热板830再将热量发散到散热结构8100外部,这样功能组件810的热量能够得到有效散发,保证了功能组件810的正常使用。
本申请实施方式的散热结构8100可以应用于图像传感器8111的散热,如应用于拍摄装置等的图像传感器8111的散热。本申请实施方式的散热结构8100还可以应用于存储器、处理器等部件的散热,如应用于双倍速率同步动态随机存储器(Double Data Rate SDRAM,DDR SDRAM)、数字信号处理器(Digital Signal Processing,DSP)等部件的散热。在本申请实施方式中,以散热结构8100应用于相机的图像传感器8111的散热为例子进行说明。
图像传感器8111是相机的重要组件,是一种将光信号转换成电子信号的部件,广泛应用在数码相机和其它拍摄设备中,由于图像传感器8111的像素越多,图像传感器8111的尺寸就越大,在相机的使用过程中,图像传感器8111的发热量就越大,而图像传感器8111是设置在电路板812上的,电路板812和图像传感器8111的热胀冷缩系数不同,在膨胀和收缩的过程中,会造成连接电路板812和图像传感器8111之间的焊点脱落,降低图像传感器8111的使用寿命,从而降低相机的使用寿命。
需要指出的是,热量传递的方式主要有三种,分别为热传导、热辐射和对流。热传导为相互接触的物体之间的热传递方式,如金属间的导热。热辐射为物体之间通过放射和吸收彼此的红外线起到热量传递的作用,如物体接收到太阳辐射后温度上升。对流是通过流体的流通进行导热的方式,如暖气片加热房间内的空气。
本申请实施方式的散热结构8100主要利用热传导和热辐射进行散热。即功能组件810上的发热器件在工作中发热后,通过热传导和热辐射将热量传递给电路板812,电路板812同样通过热传导和热辐射将热量传递给第一导热层820,同时电路板812还通过热辐射将部分热量传递给散热板830,第一导热层820同样通过热传导和热辐射将热量传递给散热板830,最后散热板830通过热传导和热辐射的方式将自身的热量传递到外部空间或外部物体,在散热结构8100上构成一条从功能组件810到散热板830再到散热结构8100外部的热量传递通道,从而起到对功能组件810进行降温的作用。
具体地,第一导热层820可以包括导热硅脂、导热凝胶和导热垫片中的至少一种。导热硅脂具有较佳的导热性,良好的电绝缘性,以及较宽的使用温度(-50℃~230℃)。导热凝胶具有较长的使用寿命,可以保持较长时间不会干涸粉化。导热垫片的寿命较低,但是便于更换。在本申请实施方式中,第一导热层820为导热硅脂,导热硅脂可以涂设于电路板812的第二面8122,用于将电路板812上的热量传导到散热板830上。而且,利用导热硅脂形成第一导热层820,第一导热层820能够较好地贴合到电路板812的第二面8122以及第二 面8122上的电子器件811,使得第一导热层820与第二面8122以及第二面8122上的电子器件811能够实现基本无空气间隙的接触,提升了散热效率。同样地,散热板与第一导热层820也能够实现基本无空气间隙的接触,进一步提升了散热效率。
在某些实施方式中,散热板830包括金属散热板。如此,金属制成的散热板830具有良好的导热性,能够快速地将功能组件810上的热量经由第一导热层820导出到散热板830上。
具体地,金属散热板可以采用银(Ag)、铜(Cu)、金(Au)、铝(Al)、钠(Na)、铁(Fe)、铅(Pb)或合金等金属制成。本申请实施方式的散热板830采用铝制成的金属散热板。用金属铝制成散热板830,能够较快地将功能组件810上的热量经由第一导热层820导出到散热板830上,且成本较低,而且成型也较容易。
当然,在其它实施方式中,散热板830还可以采用其它可替代的材料制成,其它可替代的材料可以包括其它金属或者非金属材料,在此不多加赘述。
在某些实施方式中,散热板830的表面呈黑色。如此,表面黑色的散热板能够较快地吸收热量。
具体地,根据基尔霍夫定律,相同物体的前提下,黑色物体通过热辐射吸收与辐射热量的速率比其它颜色快。可以理解,吸收热量表示吸收其它物体发出的热辐射,辐射热量为自身发出的热辐射。因此,当散热板830的表面为黑色时,散热板830在接收从电路板812和第一导热层820一侧的热辐射的速率较快,能够提升散热板830通过热辐射方式吸收功能组件810的热量的速率。并且散热板830表面为黑色时发出热辐射的量较大,能够提升散热板830将吸收的热量发散到散热结构8100外部的能力,从而提升散热结构8100的散热能力。
在某些实施方式中,散热板830表面设有热辐射层。如此,热辐射层能够提升散热板830发出热辐射的能力,从而提升散热板830将吸收的热量发散到散热结构8100外部的能力,从而提升散热结构8100的散热能力。
具体地,热辐射层可以是涂在散热板830表面的热辐射涂料,热辐射涂料能够提升散热板830的散热效果。热辐射涂料可以涂在散热板830与第一导热层820相背的一面,也可以涂在散热板830全部表面。在本申请实施方式中,热辐射层设在散热板830与第一导热层820相背的一面。
当散热板830由金属铝制成时,热辐射层还可以由阳极氧化得到,金属铝经过阳极氧化后,会在表面生成一层氧化铝膜,这层氧化铝膜可以增强散热板830发出热辐射的能力,氧化铝膜还具有良好绝缘性和耐磨性,对散热板830起到保护作用,能提升散热板830和热辐射层的寿命。
可以理解,在某些实施方式中,散热板830表面呈黑色且散热板830表面设有热辐射层。
请参阅图15,在某些实施方式中,与第一导热层820相背的散热板830的一表面832呈凸凹状。如此,能够增加散热板830与第一导热层820相背的一表面832的表面积,提升散热板830所发出热辐射的总量,还能增大散热板830和空气接触的面积,能增加散热板830通过热传导传递给空气的热量,从整体上提升散热板830发散热量的效果。
如图15所示,本申请实施方式的散热板830的表面832所呈的凸凹状为波浪型。在其它实施方式中,散热板830的表面还可以形成有多个凹槽、多个孔等结构,以提升散热板830的表面积,增强散热板830发出热辐射的能力。
在某些实施方式中,电路板812包括陶瓷板。具体地,陶瓷板和电子器件811具有更匹配的热膨胀系数,在相同的温度差下,陶瓷板和电子器件811由于热胀冷缩引起的体积变化基本一致,能有效减少因热膨胀系数不同导致的电子器件811和电路板812之间的焊点脱落问题。同时,陶瓷板还具有良好的热导率,即陶瓷板具有更好的导热性能,能够有效地将电子器件811产生的热量传递到第一导热层820,从而传递到散热板830,最终将热量发散到散热结构8100外部。
请参阅图15,在某些实施方式中,电子器件811设在第一面8121和第二面8122,设在第一面8121的电子器件811包括以下至少一种:图像传感器8111、处理器、存储器。设在第二面8122的电子器件811包括以下至少一种:电容器、电阻器和电感器。
如此,设在第一面8121和第二面8122的电子器件811的热量能够经由电路板812和第一导热层820,将热量传递到散热板830上,再由散热板830将热量发散到散热结构8100外部。
具体地,设在第二面8122的电子器件811还可以和第一导热层820贴合,第一导热层820可以直接将电子器件811的热量传递给散热板830。
电容器、电阻器和电感器等可以通过表面贴装技术(SMT)设置在电路板812上,以提升电容器、电阻器和电感器等和电路板812的结合度。
当然,在其它实施方式中,图像传感器8111、处理器、存储器、电容器、电阻器、电感器还可以设在第一面8121和第二面8122的任意一面,电子器件811还可以包括上述电子器件811外的其它器件。
请参阅图15和图17,在某些实施方式中,散热结构8100包括支架组件840。功能组件810安装于支架组件840。如此,能将功能组件810固定于支架组件840,可以防止功能组件810松动,保证功能组件810的正常工作。
具体地,功能组件810可以设置于支架组件840内部,或者部分地设置于支架组件840内部,支架组件840能够对功能组件810起到支撑和保护作用。
请参阅图15和图17,在某些实施方式中,支架组件840包括第一端盖841和安装柱843,安装柱843设在第一端盖841,电路板812弹性连接安装柱843。
如此,可使得支架组件840的振动较少地传递至电路板812,保证电路板812上的电子器件811的正常工作。
具体地,散热结构8100在应用到电子设备时,由于使用环境等因素,电子设备在使用过程中通常伴随有振动,振动对于电路板812上的电子器件811来说,会造成不良影响,例如,长时间下来会使得电子器件811与电路板812之间的连接变得松动,又如,对于对振动特别敏感的电子器件811,例如图像传感器8111,少许振动都可能会造成图像传感器8111的成像模糊。因此,电路板812弹性连接安装柱,通过弹性的方式减少支架组件840的振动传递至电路板812上,保证了电路板812上的电子器件的正常工作。
