Abstract
移动终端设备后盖结构，包括后盖（01）与中框（02），所述后盖（01）与所述中框（02）为分离式设计，通过布置在所述后盖（01）四周的卡扣（1）和中框（02）上对应的卡座（3）配合，再辅以插股（2）与股座（4）的配合，来限制后盖（01）与中框（02）相对移动。同时，后盖（01）上相对的两条边（011, 012）分别设置为统一的内卡扣（03）和统一的外卡扣（04），使得在打开后盖（01）时，只要解脱后盖（01）上相邻两边的卡扣（1）和卡座（3）配合，在顺相同方向滑动即可取下后盖（01），而不用同现有设计那样需要同时解脱四边的卡扣和卡座之间的结合。在后盖（01）上设置多个卡扣（1）以保证密封性的前提下，开启后盖（01）的方式更加省力，用户体验更好。
Description
本发明涉及移动终端领域，尤其涉及后盖可拆卸的移动终端。
目前市面上的移动终端，电池大多设置于该移动终端的背部，同时为了实现尽可能长的续航时间和较薄的机身设计，使得电池也采用扁平的设计结构，占据该移动终端背部的大部分面积。
而移动终端的后盖分可拆卸和不可拆卸两种，相对于不可拆卸后盖的移动设备，可拆卸后盖的移动设备可以实现更换电池、插拔电话卡和存储卡等功能，带给使用者较好的用户体验，但可拆卸后盖的移动终端在整机密封性上相对于不可拆卸后盖的移动终端还是有一定欠缺。
可拆卸后盖主要是以塑胶等非金属材料为主，为了保证后盖与中框能尽量贴合密封，后盖通常用卡扣结构与中框固定，同时在后盖和中框上预留相互配合的插股以防止发生相对窜动。但是，如果只设定少数的卡扣予以连接，将使得该移动终端出现密封不良的隐患；而设置过多的卡扣结构，虽然密封性能得到一定改善，但对消费者的打开后盖这一过程增加了难度，用户体验较差。
发明内容
本发明的目的在于提供一种既实现有效密封，又能简单开启和闭合的移动终端设备后盖结构，提供如下技术方案：
包括后盖和中框，所述后盖和所述中框均为长方形；所述后盖的第一长边内表面和第一短边内表面上统一设置内卡扣，所述内卡扣设被卡持面和底座，
所述被卡持面由所述底座连接于所述后盖上，相对于所述底座朝向所述后盖内部延伸；所述后盖内表面的第二长边和第二短边上统一设置外卡扣，所述外卡扣设被卡持面，所述被卡持面由所述底座连接于所述后盖上，相对于所述底座朝向所述后盖外部延伸；所述中框在所述内卡扣和所述外卡扣的位置设有与之对应的卡座，所述卡座上设有水平的卡持面，所述卡持面与所述被卡持面配合，限制所述后盖与所述中框在竖直方向上的相对运动；所述后盖内表面设有插股，所述中框上设有与所述插股配合的股座，所述插股上设竖直方向上的被固持面，所述股座上设竖直方向上的固持面，所述固持面与所述被固持面配合，限制所述后盖与所述中框在水平方向上相对运动。
本发明移动终端后盖拆卸结构，通过在所述后盖的内表面上，所述第一长边和所述第二长边上设置所述内卡扣，同时在所述第二长边和所述第二短边上设置所述外卡扣，再辅以所述插股，使得配置有对应所述卡座和对应所述股座的所述中框可以和所述后盖紧密结合，实现本发明移动终端内部空间的密封，并且在开启所述后盖的过程中，不需要像现有移动终端设备一样依次打开四个边上的所述卡扣，只要打开相邻的两边上的卡扣，就可以顺次推出所述后盖，解除所述后盖与所述中框之间的连接。本发明方案相较于现有技术，在不增加产品复杂度的前提下，拥有更简单的打开方式和更好的密封效果，具备更好的用户友好度，提升用户体验。
为了更清楚地说明本发明的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这
些附图获得其他的附图。
图1是本发明移动终端后盖的示意图；
图2是本发明移动终端后盖的截面示意图。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本发明保护的范围。
请参阅图1、图2的移动终端，整个终端呈长方形，包括后盖01和中框02，所述后盖01扣合在所述中框02上，二者也均为长方形。所述后盖01与所述中框02的扣合动作由两组相互配合的机构实现：所述后盖01内表面两条长边011和两条短边012上设有卡扣1和插股2，所述中框02与所述后盖01配合的外表面两长边021和两短边022设有对应的卡座3和股座4，所述卡座3上设有水平的卡持面31，所述卡扣1设有水平的被卡持面11，所述卡持面31与所述被卡持面11配合，限制所述后盖01与所述中框02在竖直方向上的相对运动。所述股座4上设竖直方向上的固持面41，所述插股2上设竖直方向上的被固持面21，所述固持面41与所述被固持面21配合，限制所述后盖01与所述中框02在水平方向上相对运动。由此，所述后盖01被固定在所述中框02上，形成密封的内部空间，保护本发明终端内部的各组件。
所述卡扣1的所述被卡持面11由底座12连接于所述后盖01上，由于所述被卡持面11的朝向不同而分为内卡扣03和外卡扣04，所述内卡扣03的所述被卡持面11相对于所述底座12朝向所述后盖01的内部延伸，所述外卡扣04的所述被卡持面11相对于所述底座12朝向所述后盖01的外部延伸。所述
内卡扣03和所述外卡扣04在所述后盖01的同一侧边上取出的方向不同，而所述内卡扣03和所述外卡扣04在两相对侧边上分别设置时，取出的方向则相同。在本发明方案中，所述后盖01的第一长边111和第一短边121上统一设置为所述内卡扣03，所述后盖01的第二长边112和第二短边122上统一设置为所述外卡扣04，相应的所述中框02上的所述卡座2也与所述内卡扣03和所述外卡扣04配合设置。
另一种表述方法，本发明涉及的移动终端包括所述后盖01和所述中框02，所述后盖01和所述中框02均为长方形，所述后盖01的所述第一长边111内表面和所述第一短边121内表面上统一设置所述内卡扣03，所述内卡扣03设所述被卡持面31和所述底座12，所述被卡持面31由所述底座12连接于所述后盖01上，所述内卡扣03相对于所述底座12朝向所述后盖01内部延伸。所述后盖01内表面的第二长边112和第二短边122上统一设置外卡扣04，所述外卡扣04同样设有所述被卡持面31和所述底座12，所述被卡持面31也同样由所述底座12连接于所述后盖01上，所述外卡扣04相对于所述底座12朝向所述后盖01外部延伸。
所述中框02在所述内卡扣03和所述外卡扣04的对应位置设有与之对应的卡座3，所述卡座3上设有水平的卡持面31，所述卡持面31与所述被卡持面11配合，限制所述后盖01与所述中框02在竖直方向上的相对运动。所述后盖01内表面设有插股2，所述中框02上设有与所述插股2配合的股座4，所述插股2上设竖直方向上的被固持面21，所述股座4上设有竖直方向上的固持面41，所述固持面41与所述被固持面21配合，限制所述后盖01与所述中框02在水平方向上的相对运动。
相较于当前市面上的终端后盖，往往四条侧边都统一设置所述外卡扣04或所述内卡扣03，这样的设置较为简单，但操作者在开启后盖时需要对后盖的四条侧边全部扣开后才能取下，因为所述内卡扣03或所述外卡扣04设置在
相对两条侧边上时的取出方向相反。而本发明方案的设置，只需要操作者扣开所述后盖的一条所述长边011及一条所述短边012，由于相对的所述长边011和所述短边012上的所述卡扣1的取出方向相同，因此在一边所述卡扣1解脱后，另一边所述卡扣1也顺同一方向滑出。只需要打开两个侧边上的所述卡扣1即可实现整个所述后盖01的取下。
需要强调的是，本方案中所述后盖01的所述第一长边111和所述第一短边121并没有定义其位置的功能，所述第一长边111和所述第一短边121可以是所述后盖01上的任意一条长边011和短边012，此处的所述第一长边111和所述第一短边121为的是与所述第二长边112和所述第二短边122区别开，以实现在相对的所述长边011和相对的所述短边012上统一设置不同的所述内卡扣03和所述外卡扣04作用。
一些实施例中，在所述后盖01与所述中框02接触位置设置一段凹槽05，因为密封的要求，所述后盖01与所述中框02之间的接缝处会相对紧密结合，所述凹槽05可以辅助人手开启所述后盖01。所述凹槽05可以设置在所述后盖01上或所述中框02上。
所述后盖01的四个直角处做圆弧过渡013，对于所述凹槽05的设置，可以放在所述圆弧过渡013的位置，这样可以在扣开所述凹槽05时，同时扣开所述长边011和所述短边012处的所述卡扣1，便于操作者开启整个所述后盖01。当与所述凹槽05相邻的所述长边011上的所述卡扣1统一为所述内卡扣03时，所述长边011上距所述凹槽05最近的所述卡扣1设置为所述外卡扣04。即与所述凹槽05相邻的是所述第一长边111时，所述第一长边111上距所述凹槽05最近的所述卡扣1被设置为所述外卡扣04；或所述凹槽05相邻的所述长边011上的所述卡扣1统一为所述外卡扣04时，所述长边011上距所述凹槽05最近的所述卡扣1设置为所述内卡扣03即与所述凹槽05相邻的是所述第二长边112时，所述第二长边112上距所述凹槽05最近的所述卡扣1被
设置为所述内卡扣03，这样的交叉设置可以进一步防止所述后盖01相对于所述中框02因外力作用向能够解脱所述卡扣1的扣合方向运动时，所述后盖01被意外开启。当所述后盖01上有一个反向解脱的所述卡扣1时，就能够避免此现象的发生。而且，因为反向的所述卡扣1在开启所述凹槽05的时候已经被打开，所以并不影响后续的同一方向开启所述后盖01的动作。同理的，所述短边012上也可进行类似的设计：当所述凹槽05相邻的所述短边012上的所述卡扣1统一为所述内卡扣03时，所述短边012上距所述凹槽05最近的所述卡扣1设置为所述外卡扣04，即与所述凹槽05相邻的是所述第一短边121时，所述第一短边121上距所述凹槽05最近的所述卡扣1被设置为所述外卡扣04；所述凹槽05相邻的所述短边012上的所述卡扣1统一为所述外卡扣04时，所述短边012上距所述凹槽05最近的所述卡扣1设置为所述内卡扣03，即与所述凹槽05相邻的是所述第二短边122时，所述第二短边122上距所述凹槽05最近的所述卡扣1被设置为所述内卡扣03。
所述第一长边111上的所述内卡扣03的数量与所述第二长边112上的所述外卡扣04数量不同，具体的说，与所述凹槽05相邻的所述长边011上的所述卡扣1数量较少。在使用本发明后盖结构后，由于拆卸的过程更加轻松，于是可以在所述后盖01的四周设置比普通后盖更多的所述卡扣1来实现更好的密封效果。特别是在只需要顺方向推出即可解脱的所述第二长边112上设置更多的所述卡扣1，因为不需要操作者专门开启，所以相对于所述第一长边111上的所述卡扣1数量，适当增加所述第二长边112上的数量可以进一步提高密封效果。同理的，可以设置所述第一短边121上的所述卡扣1数量比所述第二短边122上的所述卡扣1数量更少。
所述卡扣1的主要作用在于控制所述后盖01相对于所述中框02在竖直方向上的运动，而对于水平方向的相对运动，更多由所述插股2来限制。因此，所述第一长边111和所述第二长边112上至少设有一个所述插股2，所述至少
一个插股2设置于不与所述凹槽05相邻的所述长边011上时，在最后的解脱动作中只需要相对所述股座4沿所述固持面41的方向运动即可，此时所述固持面41与所述被固持面21之间保持平行的面接触，不发生相对的旋转。而所述插股2设置于所述第二长边112上时，在开启的过程中所述插股2因为沿所述第二长边112长度方向上有高度差，因此相对所述股座4会产生一定的偏角，容易造成所述插股2或所述股座4的损坏。同理的，所述第一短边121和所述第二短边122上至少设有一个所述插股2，所述至少一个插股2设置于不与所述凹槽05相邻的所述短边012上。
类似于所述插股2的设置，一些实施例汇中，所述第一长边111和所述第二长边112上至少设有一个沿所述长边011设置的密封条06，所述至少一个密封条06设置于不与所述凹槽05相邻的所述长边011上。此时所述密封条06在解脱的过程中相对所述中框02的运动相对更小，更容易保护所述密封条06不受损害，提高所述密封条的寿命。同理的，所述第一短边121和所述第二短边122上至少设有一个沿所述短边012设置的密封条06，所述至少一个密封条06设置于不与所述凹槽05相邻的所述短边012上。
当然，也可以在所述两个长边011和所述两个短边012上同时设置所述插股2和/或所述密封条06，上述的设置是指优选项，在所述后盖01的四周设置所述插股2和/或所述密封条06可以实现更好的密封效果。
本发明移动终端可拆卸后盖结构，所述后盖与所述中框通过对所述卡扣与所述口座、所述插股与所述股座共同作用下实现定位。所述卡扣分为所述内卡扣和所述外卡扣，在所述后盖的相对两侧边上，一边设置所述内卡扣，另一边设置所述外卡扣，在开启所述后盖的过程中，只需要打开两侧边的所述卡扣，另外两侧边的所述卡扣可以顺着相同的方向推出即可实现解脱，而不需要像市面上的其它设备一样必须打开全部四边的所述卡扣才能解脱所述后盖，整个过程更加简单、流畅。同时，通过所述凹槽的设置，在两相对侧边上设置不同数
量的所述卡扣，以及所述插股和所述密封条的设置，可以在保证密封性的前提下，进一步有利于所述后盖的开启方便程度，提升用户体验。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
