下面参考图1-图13c描述根据本申请第一方面实施例的车载电子装置100。
如图1-图3所示，根据本申请第一方面实施例的车载电子装置100，包括车载电子本体11、定子件21和转子件31。其中，车载电子本体11可以为车载显示屏。在本申请下面的描述中，以车载电子本体11为车载显示屏为例进行说明。当然，本领域的技术人员可以理解，车载电子本体11还可以为其他类型的车载电子产品，例如车载电脑等。
定子件21设在车载电子本体11例如车载显示屏的后侧，定子件21的前表面上设有定子摩擦片22，转子件31设在车载电子本体11例如车载显示屏和定子件21之间，转子件31连接在车载电子本体11例如车载显示屏的后表面上，转子件31的后表面上设有转子摩擦片32，转子摩擦片32的后表面与定子摩擦片22的前表面止抵，转子件31和定子件21通过连接件41连接以使连接件41限定转子件31的轴向位移，转子件31适于带动车载电子本体 11例如车载显示屏相对于定子件21绕连接件41的中心轴线在第一位置和第二位置之间可转动。其中，车载电子本体11的第二位置(如图10b所示)可以与第一位置(如图10a所示)互相垂直，当然，车载电子本体11的第二位置还可以与其第一位置呈任意夹角，例如第二位置与第一位置的夹角为60°、150°和180°等。
例如，如图1-图3、图10a和图10b所示，车载电子本体11例如车载显示屏可以为矩形平板结构，连接件41可以从前向后依次连接转子件31、转子摩擦片32、定子摩擦片22和定子件21，其中，转子件31与车载电子本体11相连，车载电子本体11相对于转子件31可以是固定不动的，且转子件31可以相对于定子件21绕连接件41的中心轴线转动，使得车载电子本体11例如车载显示屏可以随转子件31一起相对于定子件21绕连接件41的中心轴线在上述第一位置和第二位置之间转动。其中，当车载电子本体11例如车载显示屏位于第一位置时，其长度方向为图1和图2中所示的上下方向，此时车载显示屏为竖屏状态；当车载电子本体11例如车载显示屏位于第二位置时，其长度方向为图1中所示的左右方向，此时车载显示屏为横屏状态。由此，在面对不同规格的图片及视频等影像资料时，可以实现等比例、全屏显示，同时也能够兼顾不同用户的个人使用习惯。可以理解的是，车载电子本体11可以从第一位置绕连接件41的中心轴线顺时针转动到第二位置，当然，车载电子本体11也可以从第一位置绕连接件41的中心轴线逆时针转动到第二位置。在车载电子本体11从第一位置转动到第二位置的过程中，定子件21不发生转动，当车载电子装置100应用于汽车时，定子件21可以固定连接在汽车(例如汽车内的仪表台)上，车载电子本体11和转子件31一起相对于定子件21转动。由此，车载电子本体11例如车载显示屏可以完成在第一位置和第二位置之间的相互切换，从而给用户提供了更好的视听享受。
其中，在车载电子本体11例如车载显示屏转动的过程中，定子摩擦片22和转子摩擦片32之间相互接触会产生摩擦力，保证了车载电子本体11例如车载显示屏在第一位置和第二位置之间的稳定切换，并使用户具有良好的手感。而且，车载电子本体11例如车载显示屏在转动至第一位置或第二位置时，上述摩擦力将阻止车载电子本体11的继续转动，使车载电子本体11例如车载显示屏可以保持在第一位置或第二位置，从而保证了车载电子本体11例如车载显示屏位于第一位置或第二位置时的定位。
根据本申请实施例的车载电子装置100，通过在车载电子本体11例如车载显示屏的后侧设置转子件31、定子件21、以及将转子件31和定子件21连接的连接件41，并使车载电子本体11例如车载显示屏可以与转子件31一起相对于定子件21绕连接件41的中心轴线在第一位置和第二位置之间转动，由此，车载电子本体11例如车载显示屏可以实现在第一位置和第二位置之间的相互切换，从而可以给用户提供更好的视听享受，极大地方便了用户。而且，通过在转子件31和定子件21之间设置相互止抵的转子摩擦片32和定子摩擦片22，当 车载电子本体11例如车载显示屏在转动过程中，使用户具有良好的手感，且车载电子本体11例如车载显示屏在转动至第一位置或第二位置时，可以使车载电子本体11例如车载显示屏保持在第一位置或第二位置，定位良好。
在本申请的一个实施例中，连接件41为连接轴，连接件41穿过转子件31和定子件21后与固定螺母42螺纹连接。例如，如图1-图3、图6a-图6d所示，定子件21、定子摩擦片22、转子件31和转子摩擦片32上均形成有与连接件41相配合的通孔，连接件41可以从前向后依次穿过转子件31、转子摩擦片32、定子摩擦片22和定子件21上的通孔后与固定螺母42螺纹连接。此时通过调节固定螺母42对连接件41的拧紧力，可以调节连接件41和固定螺母42之间的转子件31、转子摩擦片32、定子摩擦片22和定子件21的锁紧力，保证车载电子装置100的通过连接件41连接的各个部件之间互相接触，并可以在其接触面之间产生一定的正压力，从而接触面之间会产生摩擦，避免转子件31和车载电子本体11在车载电子本体11的第一位置和第二位置之间随意自由转动，进一步保证了车载电子本体11位于第一位置或第二位置时的定位。而且，通过采用连接轴和固定螺母42螺纹连接的方式，方便了转子件31、转子摩擦片32、定子摩擦片22和定子件21之间的装拆。
在本申请的进一步实施例中，车载电子装置100进一步包括至少一个碟簧51，碟簧51套设在连接件41上，碟簧51与定子件21的后表面止抵。例如，如图1-图4c所示，碟簧51在其轴向上可以大致呈锥形，且碟簧51止抵在定子件21的后表面和固定螺母42的前表面之间，通过调节固定螺母42对连接件41的拧紧力，可以调节碟簧51的压缩量，从而可以控制车载电子装置100的通过连接件41连接的各个部件之间的正压力，进而调节各个部件接触面之间的摩擦力，由此，车载电子装置100的阻尼和用户转动车载电子本体11例如车载显示屏时所需的旋转力均可以调节，以方便不同的用户操作，同时车载电子装置100的阻尼可以保证车载电子本体11例如车载显示屏位于第一位置或第二位置时的稳定性，同时用户转动车载电子本体11例如车载显示屏时，手感良好。
例如在图1-图3的示例中示出了四个碟簧51，四个碟簧51设在定子件21和固定螺母42之间，且四个碟簧51中前侧的两个碟簧51对合设置即两个碟簧51彼此相对地设置，后侧的两个碟簧51也对合设置，从而四个碟簧51可以在较小的空间内承受较大的载荷，进一步方便了用户调节转动车载电子本体11例如车载显示屏时所需的旋转力，而且，碟簧51单位体积的变形能较大，具有良好的缓冲吸震能力，具有较长的寿命，由此，节省了车载电子装置100的占用空间，提高了车载电子装置100的寿命。可以理解的是，碟簧51的具体个数可以根据实际装配要求具体设置，以更好地满足实际要求。
更进一步地，碟簧51与定子件21的后表面之间设有压片52。例如，如图1-图3、图5a-图5c所示，压片52为圆环形结构，且压片52上形成有与连接件41相适配的通孔，以 便连接件41穿过压片52，使压片52套设在连接件41上，压片52止抵在定子件21的后表面和碟簧51的前表面之间。由此，通过在碟簧51与定子件21之间设置压片52，可以为碟簧51的前表面提供一个更平整的平面，使碟簧51与压片52之间的接触面上的正压力的分布更加均匀，从而使车载电子装置100的通过连接件41连接的结构之间的正压力的分布更加均匀，使得调节连接件41和固定螺母42之间的锁紧力和碟簧51的压缩量进而调节车载电子装置100的阻尼可控。
在本申请的一个具体实施例中，连接件41的外周面具有沿轴向延伸的至少一个平面部412，连接件41的除平面部412之外的外周面上具有与固定螺母42配合的外螺纹413。例如，如图1-图3、图6a-图6d所示，平面部412沿连接件41的轴向延伸，外螺纹413沿连接件41的轴向螺旋延伸，固定螺母42的内周面上形成有内螺纹，连接件41的外螺纹413和固定螺母42的内螺纹相配合，由此，通过在连接件41的外周面上设置平面部412，使得整个连接件41的外周形状为非圆形，从而可以达到螺纹防松的效果，使连接件41与固定螺母42连接可靠，而且，可以调节连接件41和固定螺母42之间的锁紧力，结构简单，方便加工。其中，平面部412的轴向延伸长度可以大于外螺纹413的轴向延伸长度。
例如在图6a-图6d的示例中，连接件41具有两个互相平行的平面部412，且两个平面部412关于连接件41径向相对，同时，定子件21和压片52上的通孔可以均为与连接件41相适配的大致长圆形孔。由此，在转子件31和车载电子本体11绕连接件41的中心轴线转动的过程中，定子件21不转动，从而定子件21的通孔可以卡住连接件41，使连接件41不发生转动，进而保证连接件41和固定螺母42之间的螺纹连接不会松动，保证了连接件41和固定螺母42之间的各个部件间的锁紧力。同样地，压片52的长圆形孔卡设在连接件41外，压片52也不发生转动，从而同样可以起到防松的效果，且可以更好地为碟簧51的前表面提供一个平整的平面。这里，需要说明的是，“大致长圆形孔”由两段直边段和两个弧段构成，且两段直边段平行间隔设置，两个弧段分别位于两段直边段的两端，以构成封闭的图形。
优选地，连接件41为空心轴。例如，如图1-图3、图6a-图6d所示，连接件41为连接轴，其内部形成有沿其轴向贯通的通孔，由此，车载电子本体11例如车载显示屏与其他装置例如电源的连接线可以穿过上述通孔与其他装置例如电源相连，从而避免了车载电子装置100的四周缠绕连接线，当转动车载电子本体11时，可以避免车载电子装置100中的各个部件拖曳连接线而影响车载电子本体11例如车载显示屏的转动或将连接线拽断等，进而方便了车载电子装置100的使用，保证了车载电子装置100使用的安全性及可靠性，而且，保证了车载电子装置100的美观。
在本申请的进一步实施例中，车载电子装置100进一步包括锁止件43，锁止件43设在 车载电子本体11和转子件31之间，锁止件43和转子件31中的其中一个上设有至少一个锁止凸起431，锁止件43和转子件31中的另一个上形成有至少一个锁止槽311，当车载电子本体11转动至第一位置或第二位置时锁止凸起431配合在锁止槽311内。例如，当锁止件43和转子件31中的其中一个上设有一个锁止凸起431时，锁止件43和转子件31的另一个上可以设有至少两个锁止槽311，这至少两个锁止槽311中的其中两个分别与车载电子本体11例如车载显示屏转动至第一位置和第二位置时的位置对应，以在车载电子本体11例如车载显示屏转动至第一位置或第二位置时锁止凸起431可以配合在对应的锁止槽311内，此时车载电子本体11处于锁止状态，进一步避免了转子件31和车载电子本体11在车载电子本体11的第一位置和第二位置之间随意自由转动，进一步保证了车载电子本体11位于第一位置或第二位置时的定位；或者，当锁止件43和转子件31的其中一个上只形成有一个锁止槽311时，锁止件43和转子件31的另一个上可以设有至少两个锁止凸起431，这至少两个凸起431中的其中两个分别与车载电子本体11例如车载显示屏转动至第一位置和第二位置时的位置对应，以在车载电子本体11例如车载显示屏转动至第一位置或第二位置时锁止槽311可以与对应的锁止凸起431配合，此时车载电子本体11处于锁止状态，同样进一步避免了转子件31和车载电子本体11在车载电子本体11的第一位置和第二位置之间随意自由转动，进一步保证了车载电子本体11位于第一位置或第二位置时的定位。
而且，当车载电子本体11处于锁止状态时，在转动车载电子本体11例如车载显示屏使之从第一位置和第二位置中的其中一个位置转动到第一位置和第二位置中的另一个位置的过程中，此时需要较大的启动力矩，即用户需要较大的旋转力才能使得车载电子本体11克服锁止凸起431和锁止槽311之间的锁止力而发生转动，当锁止凸起431与锁止槽311脱离配合时，使车载电子本体11继续转动所需的转动力矩趋于稳定均匀，当车载电子本体11即将转动至第二位置或第一位置时，锁止凸起431转至相应的锁止槽311，此时转子件31和锁止件43之间的摩擦力减小，车载电子本体11的所需的转动力矩减小，从而车载电子本体11将快速转动至第二位置或第一位置，并完成锁止凸起431和相应的锁止槽311的配合。同时，通过设置锁止凸起431和锁止槽311，用户将通过转动车载电子本体11例如车载显示屏的手感得知车载电子本体11例如车载显示屏已转至第二位置或第一位置，方便了用户对车载电子本体11例如车载显示屏的转动，进而完成车载电子本体11在第一位置和第二位置的切换。
在本申请的一个可选实施例中，锁止件43套设在连接件41上，锁止件43的朝向转子件31的一侧表面上设有沿连接件41的径向相对的两个锁止凸起431，转子件31的朝向锁止件43的一侧表面上形成有沿连接件41的周向均匀间隔设置的四个锁止槽311。由此，锁止件43和转子件31之间受力均匀，可以进一步保证用户在旋转车载电子本体11例如车载 显示屏到第一位置或第二位置时的手感，保证了车载电子本体11可以在第一位置和第二位置之间相互切换，而且，锁止件43上的两个锁止凸起431关于锁止件43的中心轴线对称，转子件31上的四个锁止槽311关于转子件31的中心轴线对称，保证了锁止件43和转子件31的美观。
例如，如图1-图3、图7a-图7c所示，锁止件43为圆环结构，且锁止件43上形成有与连接件41相适配的大致长圆形孔，锁止件43上的两个锁止凸起431和转子件31上的四个锁止槽311相对设置。例如，当车载电子本体11位于第一位置时，锁止件43上的两个锁止凸起431分别配合在转子件31上的彼此相对的两个锁止槽311内，此时车载电子本体11处于锁止状态。转动车载电子本体11，使上述两个锁止槽311转离上述两个锁止凸起431，当车载电子本体11即将转至第二位置时，转子件31上的另外两个锁止槽311将转至上述两个锁止凸起431处，并与其快速完成配合，使车载电子本体11转至第二位置并保持在第二位置。
在本申请的一个可选实施例中，转子件31和定子件21中的其中一个上设有朝向转子件31和定子件21中的另一个延伸出的限位块211，转子件31和定子件21中的另一个上形成有弧形槽312，限位块211配合在弧形槽312内以使车载电子本体11例如车载显示屏在上述第一位置和第二位置之间转动。由此，限位块211可以在弧形槽312内运动，以使转子件31可以相对于定子件21发生转动，从而实现了车载电子本体11在第一位置和第二位置之间的转动。
而且，在弧形槽312沿转子件31的周向延伸时，其延伸的长度可以根据车载电子本体11的第一位置和第二位置之间的夹角等设置。例如，当车载电子本体11的第一位置和第二位置相互垂直时，弧形槽312在转子件31上对应的圆心角可以设置为90°(如图8a-图8c所示)。
具体地，例如，如图1-图3、图8a-图9c所示，定子件21上设有朝向转子件31延伸出的限位块211，转子件31上形成有弧形槽312，弧形槽312可以设在转子件31的边缘，且弧形槽312由转子件31的边缘朝向转子件31的中心凹入形成，限位块211可以配合在弧形槽312内，且限位块211可以在弧形槽312内沿弧形槽312的延伸方向运动，以使转子件31可以相对于定子件21发生转动，从而实现了车载电子本体11在第一位置和第二位置之间的转动。其中，当车载电子本体11转至第一位置或第二位置时，限位块211正好分别位于弧形槽312的两端，弧形槽312的两端侧壁对限位块211具有限位作用，避免限位块211相对于弧形槽312继续运动，由此，保证了车载电子本体11例如车载显示屏在第一位置或第二位置时的稳定性。可以理解的是，弧形槽312还可以与转子件31的边缘间隔设置，且弧形槽312为贯穿转子件31的前表面和后表面的弧形通孔(图未示出)，由此，可以进一步 保证弧形槽312的侧壁对限位块211的限位作用，从而保证了车载电子本体11例如车载显示屏在第一位置或第二位置时的稳定性。
当然，本申请不限于此，转子件31上可以设有朝向定子件21延伸出的限位块211，定子件21上形成有弧形槽312。由此，同样可以通过限位块211在弧形槽312内运动实现转子件31相对于定子件21的转动，从而实现车载电子本体11在第一位置和第二位置之间的转动，且可以保证车载电子本体11在第一位置或第二位置时的稳定性。
而且，如图8a-图8c所示，当转子件31上形成有弧形槽312时，转子件31上与弧形槽312径向相对的部分可以被一段弧或直线切掉一部分，使得转子件31的重心位于其中心轴线上，从而在用户转动车载电子本体11而使转子件31转动的过程中，转子件31不会产生使自身转动的附加的力矩而影响车载电子本体11的转动和定位，保证了车载电子本体11转动的稳定性和定位，而且，减少了转子件31的用材量，降低了成本。
如图1-图3、图8a-图9c所示，限位块211上套设有缓冲套212，由此，缓冲套212可以缓冲限位块211与弧形槽312之间的碰撞，改善了限位块211与弧形槽312之间的碰撞噪音和用户的手感。可选地，缓冲套212可以为橡胶套，当然，缓冲套212还可以为其他能起到减缓限位块211与弧形槽312之间的碰撞的缓冲结构。
定子件21上形成有至少一个定位孔21a，转子件31上形成有至少一个限位孔31a，而且，定子摩擦片22上设有至少一个朝向定子件21延伸的限位柱321，转子摩擦片32上设有至少一个朝向转子件31延伸的限位柱321，定子摩擦片22上的限位柱321穿入定子件21上的定位孔21a内，转子摩擦片32上的限位柱321穿入转子件31上的限位孔31a内，从而定子摩擦片22相对于定子件21保持静止，转子摩擦片32相对于转子件31保持静止。当转子件31绕连接件41的中心轴线转动时，转子摩擦片32随之一起转动，而定子摩擦片22与定子件21均不发生转动，进而，定子摩擦片22和转子摩擦片32之间会产生摩擦力，阻止转子件31的转动，由此，可以避免转子件31随意自由转动而导致转子件31打滑，保证了车载电子本体11在第一位置和第二位置之间的稳定切换。例如，如图1-图3、图8a-图11c所示，定子件21和转子件31上分别形成有沿周向间隔设置的四个定位孔21a和四个限位孔31a，而且定子摩擦片22和转子摩擦片32的结构可以相同，定子摩擦片22和转子摩擦片32上均设有四个限位柱321，定子摩擦片22上的四个限位柱321穿入定子件21上的四个定位孔21a内，转子摩擦片32上的四个限位柱321穿入转子件31上的四个限位孔31a内，从而在转动车载电子本体11时，定子摩擦片22和转子摩擦片32之间会产生摩擦力，保证了车载电子本体11在第一位置和第二位置之间的稳定切换。
在本申请的一些实施例中，定子摩擦片22和转子摩擦片32中的至少一个上形成有至少一个储油孔32a。也就是说，在定子摩擦片22和转子摩擦片32中，只有定子摩擦片22上 形成有至少一个储油孔32a，或者，只有转子摩擦片32上形成有至少一个储油孔32a，或者，定子摩擦片22和转子摩擦片32上均形成有至少一个储油孔32a。例如，如图11a-图11c所示，定子摩擦片22和转子摩擦片32的结构可以相同，其上均形成有一个通孔和位于通孔外侧的至少一个储油孔32a，由此，储油孔32a内可以储存油脂，当定子摩擦片22和转子摩擦片32之间发生相对转动时，储油孔32a内的油脂可以进入定子摩擦片22和转子摩擦片32之间，以改善定子摩擦片22和转子摩擦片32之间的接触面的润滑情况，使定子摩擦片22和转子摩擦片32之间的摩擦力适中，从而提高了车载电子装置100的可靠性和寿命。当储油孔32a为多个时，多个储油孔32a可以沿上述通孔的周向间隔分布例如均匀间隔分布，由此，油脂通过多个储油孔32a可以更好地分布在定子摩擦片22和转子摩擦片32之间的接触面上，以进一步改善定子摩擦片22和转子摩擦片32之间的接触面的润滑情况。
可选地，如图11a-图11c所示，定子摩擦片22和转子摩擦片32的结构可以相同，且均可以设置为方形，由此，结构简单，加工方便。而且，定子摩擦片22和转子摩擦片32可以采用耐磨、表面硬度大的材料制成，可以提高定子摩擦片22和转子摩擦片32的耐磨性，从而提高了车载电子装置100的寿命，进一步提高了车载电子装置100的可靠性。
在本申请的一个可选实施例中，转子件31通过支架61连接在车载电子本体11的后表面上，支架61包括与车载电子本体11的后表面彼此间隔开的支架本体611和设在支架本体611的外周缘且与车载电子本体11的后表面相连的支脚612，连接件41的一端设有径向向外延伸的止挡件411，止挡件411与转子件31的前表面止抵。例如，如图1-图3、图12a-图12c所示，转子件31通过支架61的支脚612与车载电子本体11相连，由此，转子件31的结构较简单，加工方便，而且，由于不同尺寸的车载电子本体11的后表面上与支架61的支脚612相连的连接位置可以相同，转子件31可以通过相同结构的支架61实现与不同尺寸的车载电子本体11的连接，从而车载电子装置100可以配备不同尺寸的车载电子本体11，继而提高了车载电子装置100的适用性。同时，由于连接件41上的止挡件411可以与转子件31的前表面止抵，止挡件411与固定螺母42在其轴向上的距离可调，从而可以调节连接件41和固定螺母42之间的锁紧力。当然，转子件31还可以直接与车载电子本体11例如车载显示屏相连，从而减少了车载电子装置100的部件数量，提高了装配效率，节约了成本。
如图1-图3所示，在车载电子装置100装配完成后，车载电子本体11的后表面与止挡件411的前表面间隔设置，当车载电子本体11发生转动时，连接件41始终不发生转动，车载电子本体11与止挡件411间隔设置可以避免车载电子本体11例如车载显示屏与止挡件411之间产生摩擦，从而磨损车载电子本体11的后表面，起到了保护车载电子本体11例如车载显示屏的作用。
可选地，如图1-图3所示，连接件41位于车载电子本体11例如车载显示屏后表面的中 央，也就是说，连接件41的中心轴线和车载电子本体11的沿前后方向的中心轴线重合，由此，与车载电子本体11相连的部件例如支架61的中心轴线与车载电子本体11的沿前后方向的中心轴线重合，从而车载电子本体11的重心位于连接件41和与车载电子本体11相连的部件例如支架61的中心轴线上，当车载电子本体11绕连接件41的中心轴线转动时，车载电子本体11不会对与其相连的部件例如支架61产生附加的力矩，从而使上述部件例如支架61的受力均匀。
此外，车载电子装置100上还可以设置固定架71，固定架71设在定子件21的后侧，固定架71上形成有通孔，以便于固定架71套设在固定螺母42的外侧，当车载电子装置100应用于汽车时，定子件21可以通过固定架71与汽车(例如仪表台等)固定连接。如图1-图3、图9a-图9c和图13a-图13c所示，定子件21的左端形成有沿上下方向间隔设置的两个第一连接件213，定子件21的右端形成有沿上下方向间隔设置的两个第一挡板214，固定架71的左端形成有沿上下方向间隔设置的两个第二挡板712，两个第二挡板712之间设有第一中间挡板713，固定架71的右端形成有沿上下方向间隔设置的两个第二连接件711，两个第二连接件711之间设置有第二中间挡板714，其中，第一连接件213与第二挡板712扣合连接，第二连接件711与第一挡板214扣合连接，第一中间挡板713和第二中间挡板714可以分别对第一连接件213和第一挡板214起到定位作用，由此，方便了定子件21和固定架71的定位，提高了安装效率。
进一步地，如图1-图3所示，转子件31和定子件21之间可以设有密封环23，密封环23上形成有通孔，通孔的内周面、转子件31的后表面和定子件21的前表面之间限定出安装空间，定子摩擦片22和转子摩擦片32安装在该安装空间内，由此，可以避免定子摩擦片22和转子摩擦片32之间的油脂沿定子摩擦片22的径向流出而污染车载电子装置100，保证了车载电子装置100的美观和洁净。
根据本申请第二方面实施例的汽车，包括根据本申请上述第一方面实施例的车载电子装置100。
根据本申请实施例的汽车，通过采用上述的车载电子装置100，可以实现车载电子产品例如车载显示屏在其第一位置和第二位置的相互切换，且车载电子装置100美观、洁净，从而给用户提供了更好的视听享受，极大地方便了用户。
