Description

一种使用卡扣连接的壳体结构和电子设备 技术领域
本申请涉及一种锁紧结构，尤其涉及一种使用卡扣连接的壳体结构和电子设备。
背景技术
目前，电子设备在涉及到壳体连接时，一般采用的螺纹连接方式。具体来说，就是在其中一个壳体上拔模形成螺纹孔，在另一个壳体上设置与螺纹孔位置对应的通孔；然后使用螺钉穿过通孔并旋入螺纹孔锁紧，以将两个壳体固定连接。螺纹连接方式虽然能够使壳体具备可拆卸的能力，但是由于需要在壳体上开孔和旋入螺钉，会破坏壳体的完整性。因此，为了不破坏壳体的完整性，一些电子设备(例如：大屏显示设备)的壳体采用卡扣连接方式进行连接。但是，由于卡扣连接是一种利用卡扣和壳体的位置干涉实现锁紧的结构，其锁紧的可靠性取决于卡扣和壳***置的干涉量。具体来说，卡扣与壳体的干涉量越大，锁紧可靠性越高，但可拆卸性能越差；卡扣与壳体的干涉量越小，锁紧可靠性越低，但可拆卸性能越强。因此，卡扣与壳体配合的可靠性和可拆卸性能无法同时兼顾。
发明内容
本申请提供了一种使用卡扣连接的壳体结构，能够提高该壳体结构在使用过程中的可靠性和可拆卸性能。本申请还提供了一种使用该壳体结构的电子设备。
第一方面，本申请提供了一种卡扣连接的壳体结构，该壳体结构包括：第一壳体，第一壳体包括第一侧边；第二壳体，第二壳体扣合于第一侧边；第二壳体包括第二侧边，第二侧边位于第一侧边的一侧；卡扣，卡扣固定于第一侧边；卡扣包括止退片，止退片设置于第一侧边和第二侧边之间；止退片包括连接部、拆卸部和止退部；连接部一端贴近于第一侧边，另一端向靠近第二侧边的方向延伸；拆卸部一端与连接部靠近第二侧边的一端连接，另一端向远离第二侧边的方向延伸；止退部一端与连接部靠近第二侧边的一端连接，另一端向靠近第二侧边的方向继续延伸；第二侧边面向第一侧边设置有凸起部，凸起部向靠近第一侧边的方向延伸，凸起部与止退部形成位置干涉。
本申请提供的技术方案，当需要进行壳体拆卸时，作业人员可以使用拆卸工具撬动卡扣的拆卸部和连接部，使拆卸部和连接部向靠近第一侧边方向产生形变，进而带动止退部向靠近第一侧边方向产生形变，以解除凸起部和止退部的位置干涉状态，实现壳体的拆卸。由此，本申请提供的技术方案能够在不使用螺钉并且不破坏壳体外观的前提下，利用卡扣结构实现壳体之间的可靠安装和便捷拆卸，结构简单，制造成本低；并且，本申请提供的技术方案在拆卸壳体时，不破坏卡扣、壳体以及其他结构件，使上述结构件可以重复使用，降低维护成本。
可选的，卡扣包括第一定位片、第二定位片和连接片；第一定位片设置于连接片的一端，第二定位片设置于连接片的另一端；第一定位片和第二定位片向连接片的同一侧弯折形成第一凹型结构，卡扣通过第一凹型结构扣合安装于第一侧边；止退片与第一定位片并列设置于第一侧边和第二侧边之间。由此，卡扣利用第一凹型结构扣合安装于第一侧边， 实现卡扣与第一壳体的固定，那么，当第二壳体扣合与第一侧边，与通过凸起部与卡扣的止退部形成位置干涉时，卡扣就实现了对第一壳体和第二壳体的固定连接。
可选的，卡扣包括多个止退片和多个第一定位片；多个止退片和多个第一定位片交替分布在第一侧边和第二侧边之间。由此，多个止退片能够通过止退部与凸起部的位置干涉与第二壳体形成多个支点，提高卡扣对第二壳体的锁紧可靠性；同时，多个第一定位片也能够多点支撑与第一侧边，提高卡扣在第一侧边扣合的可靠性，时卡扣的姿态保持稳定。
可选的，第一侧边设置有至少一个第一孔位；第二定位片设置有至少一个第二孔位，第二孔位与第一孔位一一对应设置；第二孔位内设置有限位片，限位片一端连接于第二定位片，另一端向靠近第一定位片和连接片的方向延伸，与第一孔位形成嵌入配合。由此，该嵌入配合结构能够防止卡扣相对于第一侧边产生相对移动，保证卡扣扣合安装于第一侧边之后不会产生松脱。
可选的，第二侧边设置有至少一个第三孔位，第三孔位内设置有压紧片，压紧片一端连接于第一定位片，另一端向靠近第二定位片和连接片的方向延伸，压紧于第一侧边。由此，第二定位片压紧于第一侧边，能够防止卡扣相对于第一侧边产生相对移动。
可选的，第一定位片与第二定位片之间的距离L1大于第一侧边的厚度B1；压紧片向靠近第二定位片的方向延伸的距离L2大于或者等于距离L1和厚度B1的差值。由此，压紧片与第一侧边能够形成过盈配合而发生形变，使压紧片能够在第一侧边施加一个由形变产生的压紧力。卡扣在压紧力的反作用下产生向第二侧边移动的趋势，使第二定位片压紧于第一侧边，防止卡扣相对于第一侧边产生相对移动。
可选的，第二壳体还包括连接边和第三侧边；第三侧边和第二侧边设置于连接边的同一侧，向远离连接边的方向延伸形成第二凹型结构，第二壳体通过第二凹型结构扣合安装于第一侧边。由此，第二凹型结构能够限制第二壳体和第一侧边产生大的相对位移，使卡扣隐藏在第二壳体之内，提高壳体结构的外观整体性。
可选的，止退部远离第一侧边的一端在未受到外力作用的状态下与第一侧边之间的距离L3大于第一侧边与第二侧边之间的距离L4。止退部与第二侧边形成过盈配合，止退部会受到第二侧边的压迫而向第一侧边方向产生形变，使止退部在第二侧边施加一个由形变产生的压力，当第一壳体和第二壳体产生相互脱离的趋势时，止退部会与凸起部产生位置干涉而卡住第二壳体，从而限制第一壳体和第二壳体产生相对移动，使第一壳体和第二壳体不会相互脱离。
第二方面，本申请提供一种电子设备，该电子设备包括：显示屏、光学部件和本申请第一方面提供的卡扣结构；第一壳体还包括壳体底面；第一侧边一端与壳体底面连接，另一端向远离壳体底面方向延伸；第二壳体还包括连接边、第三侧边和第四侧边；连接边设置于第一侧边的远离壳体底面的一端，连接边与壳体底面平行；第二侧边和第三侧边面向壳体底面设置于连接边的同一侧，向远离连接边的方向延伸形成第二凹型结构，第二壳体通过第二凹型结构扣合安装于第一侧边；第四侧边设置于连接边的另一侧，向远离第二侧边和第三侧边的方向延伸；显示屏与第四侧边设置于连接边的同一侧，显示屏通过封屏胶粘贴固定于连接边；光学部件设置于显示屏和第一壳体之间，固定于壳体底面。
本申请提供的技术方案，能够在不使用螺钉或者其他破坏壳体外挂的技术方案的前提下，利用卡扣结构实现电子设备壳体之间的可靠安装和便捷拆卸，结构简单，制造成本低； 另外，本申请实施例提供的技术方案在拆卸壳体时，不破坏卡扣、壳体以及其他结构件，使上述结构件可以重复使用，降低维护成本。

具体实施方式
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地描述。显然，所描述的实施例是本申请的一部分实施例，而不是全部实施例。基于本申请的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所得到的其他实施例，都属于本申请的保护范围。
图1是目前电子设备使用卡扣连接的示意图。如图1所示，电子设备的卡扣与壳体是利用位置干涉实现锁紧，其锁紧的可靠性取决于卡扣和壳***置的干涉量。图1示出了卡扣和壳体设计的两种大小不同的干涉量K1和K2，其中，干涉量K1大于干涉量K2。卡扣和壳体在锁紧之后，如果要进行拆卸，需要在壳体施加外力使壳体变形，以消除干涉；但是，由于壳体多为刚性结构，能够产生的变形幅度有限，因此，卡扣与壳体的干涉量越大，可拆卸性能越差，甚至导致拆卸过程中壳体损坏；卡扣与壳体的干涉量越小，可拆卸性能越强，但是卡扣和壳体的锁紧可靠性也会减弱。
为了解决上述问题，本申请提供了一种电子设备，该电子设备包括使用卡扣结构进行固定连接的壳体，并且电子设备的壳体使用卡扣结构固定连接之后，能够同时具备较高可靠性和可拆卸性能。在一些实施例中，该电子设备为大屏显示设备(例如：智能电视、智慧屏产品、社交电视、互联网电视等)。图2是大屏显示设备的壳体的结构示意图，如图2所示，大屏显示设备的壳体具体包括中框和后壳，其中，大屏显示设备的显示屏固定于中框的一侧，后壳则可以通过卡扣结构固定于中框的另一侧。大屏显示设备正朝着更薄更大的方向发展，目前来说，大屏显示设备的中框宽度H1多在几毫米到十几毫米之间，例如一些厂商将大屏显示设备的中框宽度H1做到了5mm左右。中框宽度H1越小，意味着大屏显示设备内部空间越小，越难以设计复杂的结构以实现壳体的连接，以一般采用的螺纹连接方式来说，需要沿着中框宽度H1方向在中框内拔模形成用于螺钉旋入的螺纹孔，然而，随着中框宽度H1的减小，中框内能够形成的螺纹孔的深度也会减小，这会使螺纹连接的可靠性下降，导致螺钉容易从螺纹孔中脱出。另外，大屏显示设备的壳体通常为薄壁结构，壳体壁厚通常只有1毫米、2毫米或者至多几毫米，在这种情况下，如果使用螺纹连接对壳体进行连接，很容易在旋入螺钉的过程中由于施力不当对壳体造成损坏。由此可见，螺纹连接已经无法满足大屏显示设备的发展需求，使用卡扣结构对大屏显示设备的壳体进行固定连接是壳体结构设计的主要方向。
本申请实施例接下来以大屏显示设备为例，对电子设备使用卡扣结构进行壳体连接，能够同时具备较高可靠性和可拆卸性能的技术方案做具体阐述说明。其中，为了便于对技术方案进行描述，在以下的内容中，第一壳体对应大屏显示设备的后壳，以第二壳体对应大屏显示设备的中框。
下面是本申请的第一实施例。
图3为本申请第一实施例提供的电子设备的结构分解图。如图3所示，该电子设备包括第一壳体100、第二壳体200和卡扣300。第一壳体100包括第一侧边110，第一侧边110设置有一个或者多个第一孔位120。当第一侧边110包括多个第一孔位120时，多个第一孔位120沿第一侧边110的长度方向(即图3中的A向)并列设置。卡扣300为U型薄壁结构，具有与第一侧边110形状匹配的第一凹型结构310，通过第一凹型结构310沿 图3中B向扣合安装于第一侧边110。第二壳体200具有与卡扣300形状匹配的第二凹型结构260，通过第二凹型结构260沿B向扣合安装于卡扣300和第一侧边110之上。
本申请实施例中，第一壳体100和第二壳体200可以使用金属材料制成，例如铁、钢、铝及其合金等；第一壳体100和第二壳体200也可以非金属材料制成，例如：塑料、玻璃、陶瓷等。卡扣300可以使用薄壁金属片制成，例如铁片、钢片、铝合金片、铝镁合金片等，以使卡扣300具有良好的强度和硬度。
图4是本申请第一实施例提供的卡扣300的C向结构示意图。如图4所示，卡扣300包括第一定位片330、第二定位片340和连接片320。第一定位片330设置于连接片320的一端，第二定位片340设置于连接片320的另一端。第一定位片330和第二定位片340向连接片320的同一侧弯折。第一定位片330设置有一个或者多个第三孔位331，第三孔位331内设置有压紧片332，压紧片332一端连接于第一定位片330，另一端向靠近第二定位片340和连接片320的方向延伸。当第一定位片330设置有多个第三孔位331时，多个第三孔位331沿A向并列设置。卡扣300还包括一个或者多个止退片350，止退片350沿A向与第一定位片330并列地设置于连接片320的同一端，并且止退片350与第一定位片330向连接片320的同一侧弯折。当卡扣300包括多个止退片350时，止退片350可以沿A向在第一定位片330的两侧对称分布。止退片350包括连接部352、止退部353和拆卸部351。连接部352一端与连接片320相连接，另一端向远离连接片320的方向延伸，连接部352与第二定位片340的距离沿远离连接片320方向逐渐增大。止退部353和拆卸部351并列设置于连接部352远离连接片320的一端。其中，止退部353一端与连接部352连接，另一端继续向远离连接部352的方向延伸，止退部353与第二定位片340的距离沿远离连接部352的方向逐渐增大；拆卸部351一端与连接部352连接，另一端远离连接部352的方向延伸，止退部353与第二定位片340的距离沿远离连接部352的方向逐渐减小。
图5是本申请第一实施例提供的卡扣300与第二壳体200的配合示意图。其中，为了便于呈现卡扣300与第二壳体200的配合状态，图5对第二壳体200的部分特征进行了去除处理。作为一种实例，卡扣300可以包括一个第一定位片330和两个止退片350，其中，两个止退片350沿A向设置于第一定位片330的两侧；在这种结构中，第一定位片330的压紧片332压接于第一侧边110之上，形成支点P，该支点P刚好位于卡扣300的中心位置；另外，位于第一定位片330两侧的两个止退片350通过各自的止退部353压接于第二壳体200，可以与第二壳体200形成过盈配合，形成支点Q，由此，卡扣300会在两侧的止退部353分别受到来自第二壳体200的沿E向的压力F0；此时，由于两处压力F0的方向相同，并且沿支点P对称，因此，两处压力F0相对于支点P的力矩能够相互平衡，从而使卡扣300的姿态保持稳定，不会相对于第一侧边110发生扭转等，从而提高卡扣300的锁紧可靠性。作为另一种实施例，卡扣300可以包括多个第一定位片330和多个止退片350，多个第一定位片330和多个止退片350地沿A向交替分布，此时，第一定位片330的压紧片332能够形成多个支点P，止退部353和第二壳体200能够形成多个支点Q，并且多个支点P和多个支点Q能够沿着A向均匀分布更长的距离，有利于提高卡扣300的锁紧可靠性。
图6是本申请第一实施例提供的卡扣300的D向结构示意图。如图6所示，第二定位片340设置有一个或者多个第二孔位341，第二孔位341与第一侧边110的第一孔位120 一一对应设置。第二孔位341内设置有限位片342，限位片342一端连接于第二定位片340，另一端向靠近第一定位片330和连接片320的方向延伸。
图7是本申请第一实施例提供的第二壳体200的结构示意图。如图7所示，第二壳体200包括连接边210、第二侧边230、第三侧边220和第四侧边240。第三侧边220和第二侧边230并列设置于连接边210的同一侧，向远离连接边210的B向延伸。第二侧边230远离连接边210的一端设置有凸起部250，凸起部250面向第三侧边220设置，向靠近第三侧边220的方向延伸。第四侧边240设置于连接边210的另一侧，向远离第三侧边220和第二侧边230的方向延伸。
图8是本申请第一实施例提供的电子设备的E向结构分解图。如图8所示，为了具体描述第一壳体100、第二壳体200和卡扣300在装配关系，本申请第一实施例在接下来的内容中，将会在压紧片332的位置对电子设备进行A1-A1向剖切、在限位片342的位置对电子设备进行A2-A2向剖切、在连接部352和止退部353的位置对电子设备进行A3-A3向剖切、在连接部352和拆卸部351的位置对电子设备进行A4-A4向剖切，并在剖切后沿A向展示剖视图，具体请参见下文对图9-图12描述的内容。
图9是本申请第一实施例提供的电子设备在压紧片332的A向剖视图。如图9所示，第一侧边110和第二侧边230之间具有间隙，第一定位片330位于第一侧边110和第二侧边230之间的间隙内。第一侧边110和第三侧边220之间具有间隙，第二定位片340位于第一侧边110和第三侧边220之间的间隙内。第一定位片330与第二定位片340之间的距离L1大于第一侧边110的厚度B1。压紧片332向靠近第二定位片340的方向延伸的距离L2大于或者等于L1和B1的差值ΔL 1，因此压紧片332与第一侧边110能够形成过盈配合而发生形变，使压紧片332能够在第一侧边110施加一个由形变产生的压紧力F1。卡扣300在压紧力F1的反作用下产生向第二侧边230移动的趋势，使第二定位片340压紧于第一侧边110，防止卡扣300相对于第一侧边110沿E向产生相对移动。
图10是本申请第一实施例提供的电子设备在限位片342的A向剖视图。如图10所示，第一孔位120和第二孔位341沿E向并列设置。限位片342的末端终止于第一孔位120内，与第一孔位120形成嵌入配合，防止卡扣300相对于第一侧边110沿G向产生相对移动，保证卡扣300扣合安装于第一侧边110之后不会产生松脱。
图11是本申请第一实施例提供的电子设备在连接部352和止退部353的A向剖视图。如图11所示，连接部352和止退部353为一体结构，连接部352和止退部353沿G向相反方向逐渐远离第一侧边110，靠近第二侧边230；止退部353远离第一侧边110的一端在未受到外力作用的自由伸展状态下与第一侧边110的距离为L3，第一侧边110与第二侧边230之间的距离为L4。距离L3大于距离L4，这样，当第二壳体200扣合安装于第一侧边110时，止退部353与第二侧边230形成过盈配合，过盈量为ΔL 2。止退部353会受到第二侧边230的压迫而向第一侧边110方向产生形变，使止退部353能够在第二侧边230施加一个由形变产生的压力F2，止退部353的末端在压力F2的作用下贴紧第二侧边230。因此，当第一壳体100和第二壳体200产生沿G向相互脱离的趋势时，止退部353会与凸起部250产生沿G向的位置干涉而卡住第二壳体200，从而限制第一壳体100和第二壳体200产生相对移动，使第一壳体100和第二壳体200不会相互脱离。
图12是本申请第一实施例提供的电子设备在连接部352和拆卸部351的A向剖视图。 如图12所示，连接部352和拆卸部351为一体结构，连接部352沿B向逐渐远离第一侧边110，靠近第二侧边230；拆卸部351沿B向逐渐靠近第一侧边110，远离第二侧边230，拆卸部351在远离连接部352的一端与第一侧边110相接触；由此，拆卸部351、第二侧边230和凸起部250在第一侧边110和第二侧边230的间隙内围成了一个楔形腔体400，即图10中的点状阴影区域。第一侧边110和凸起部250之间还具有间隙，使楔形腔体400与电子设备外部连通。
图13是本申请第一实施例提供的电子设备拆卸壳体的示意图。如图13所示，拆卸第二壳体200共包含3个步骤。步骤1：使用具有扁平形状的拆卸工具900(例如撬片、撬棒、一字型螺丝刀等)，从第一侧边110和凸起部250之间的间隙伸入到楔形腔体400内。步骤2：以凸起部250为支点，沿图11中的逆时针方向旋转拆卸工具900，以撬动连接部352和拆卸部351向靠近第一侧边110方向产生形变；由于拆卸部351、连接部352和止退部353为一体结构，因此当连接部352产生形变时，能够带动止退部353向靠近第一侧边110方向移动，同时，第二侧边230在拆卸工具900的作用下也会向远离第一侧边110的方向产生形变，使凸起部250与第一侧边110的距离增大；这样，就可以将止退部353从被凸起部250卡住的状态中脱离出来，止退部353会与凸起部250产生沿G向的位置干涉就会被解除。步骤3：沿G向使第一壳体100和第二壳体200拆卸脱离。
本申请的第一实施例提供的技术方案具有以下有益效果：
首先，止退部353与第二侧边230形成过盈配合，使止退部353的末端贴紧第二侧边230，止退部353会与凸起部250产生沿G向的位置干涉而卡住第二壳体200，从而限制第一壳体100和第二壳体200产生相对移动，使第一壳体100和第二壳体200产生不会相互脱离。拆卸部351、第二侧边230和凸起部250在第一侧边110和第二侧边230的间隙内围成了一个楔形腔体400，通过第一侧边110和凸起部250之间的间隙与电子设备外部连通；该楔形腔体400可以为拆卸工具900提供作业空间，作业人员只需要将拆卸工具900伸入到楔形腔体400内，撬动连接部352和拆卸部351向靠近第一侧边110方向产生形变，就可以带动止退部353向靠近第一侧边110方向移动，同时，第二侧边230在拆卸工具900的作用下也会向远离第一侧边110的方向产生形变，使凸起部250与第一侧边110的距离增大；这样，止退部353会与凸起部250产生沿G向的位置干涉就会被解除，使第一壳体100与第二壳体200成功拆卸脱离。
并且，由于本申请第一实施例可以通过拆卸工具900撬动拆卸部351以消除止退部353与凸起部250之间的干涉，因此卡扣300和第一壳体100设计时，无需担心卡扣300和第一壳体100的干涉量过大而导致第一壳体100无法拆卸。
因此，本申请第一实施例提供的技术方案，能够在不使用螺钉并且不破坏壳体外观的前提下，利用卡扣结构实现电子设备壳体之间的可靠安装和便捷拆卸，结构简单，制造成本低；另外，本申请第一实施例提供的技术方案在拆卸壳体时，不破坏卡扣、壳体以及其他结构件，使上述结构件可以重复使用，降低维护成本。
