本申请要求于2021年08月26日提交中国专利局的申请号为202122041253.1、发明名称为“压合支架预固定结构及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及终端领域，尤其涉及一种压合支架预固定结构及电子设备。
背景技术
目前连接器产品类型中，BTB(Board to board，板对板)连接器以其小巧、多管脚及高速传输等特点，在手机等终端设备内部诸多部件与主板或副板的连接关系中得以广泛应用。例如但不限于，摄像头、电池、天线小板等。基于BTB扣合可靠性的要求，一般都需要辅以BTB压合支架来固定BTB，以防止BTB公母头连接松脱导致功能失效等问题的发生。
以手机BTB压合支架的固定方式为例。现有一种典型的支架固定结构，采用一端侧卡扣、另一端侧背胶进行预定位，或者两端侧都通过背胶进行预固定，然后通过螺钉紧固。产线上，螺钉紧固工位与BTB压合支架组装工位之间布置有其他组装工位，若BTB压合支架预固定效果不佳，经过中间组装工位流转至螺钉锁付工位后，BTB压合支架会出现翘起、偏位、掉落等不良缺陷，直接影响效率和质量。
发明内容
本申请实施例提供了一种压合支架预固定结构及电子设备，通过结构优化能够提升待压元件的预固定可靠性。
本申请实施例第一方面提供了一种压合支架预固定结构，包括可沿第一方向压合待压元件的支架，该支架的第二方向上的两端侧的预固定部，与在第一方向上与支架相对的固定构件上设置的两个限位部，分别构建形成两个滑动限位副。两个滑动限位副均配置为：预固定部可相对于相应的限位部沿第二方向滑动，以切换于安装位和预固定位之间，限位部可在第一方向上对位于预固定位的预固定部形成限位，其中至少一个滑动限位副的限位部在预固定部切换至预固定位后形成限位；也就是说，至少一个限位关系在预固定部切换至预固定位后才形成，满足压合支架的基础装配要求，通过限位部对切换至预固定位的预固定部形成限位，在第一方向上构建对该支架的预固定。同时，在支架的本体与待压元件或固定构件之间设置有弹性件，且弹性件至少可在第一方向上受压产生形变；这样，预固定完成后，基于第一方向上的受压形变，该弹性件可施加作用力至支架本体，并在两者间形成静摩擦力，由此，该支架在垂直于第一方向的平面内可保持无滑移状态，能够实现该压合支架的可靠预固定。如此设置，压合支架预固定后具有较高的可靠性，有效规避了在工位流转过程中出现预固定失效的可能性，应用本方案，不同组装工艺流程下，均可确保流转至锁付工位后的操作工艺性，能够有效提升产线效率和质量。
另外，应用本方案，操作者得以无工具执行预固定操作，以及执行逆向维修拆卸该压合支架；执行逆向维修拆卸时，不需要更换辅料和清胶，在提高效率的基础上，可进一步降低工艺成本。
在实际应用中，该待压元件可以为BTB连接器，具体可应用于摄像头、电池、天线小板等与主板或副板连接用的BTB连接器。
示例性的，该弹性件可以为泡棉、硅胶或金属弹片，压合支架的材料可以为不锈钢或铝合金。
示例性的，该弹性件可设置在待压元件的表面或者电子设备的壳体表面，或者，该弹性件也可设置在支架本体与待压元件相对的表面上，例如但不限于采用粘接固定的方式，可避免装配操作间隔弹性件出现移位。
基于第一方面，本申请实施例还提供了第一方面的第一种实施方式：预固定部包括长度沿第二方向设置的条形孔，限位部包括可沿第一方向插装于条形孔的定位柱，在定位柱的伸出端具有卡钩，且该卡钩沿第二方向朝向支架的本体延伸形成，以在预固定部切换至预固定位后形成限位。组装时，定位柱插装于条形孔中后，卡钩自条形孔伸出后，压合支架可沿第一方向相对于该定位柱切换至预固定位，且预固定部随其向与卡钩延伸方向相反的方向位移，直至卡钩形成对支架本体的限位。具有结构简单，且操作性较好的特点。
在具体应用中，该条形孔的侧壁可与定位柱的本体间隙配合，这样，工作位切换过程中，该条形孔除满足定位柱在第二方向上的位移行程外，其侧壁还可在第三方向形成对定位柱的限位，可进一步提高预固定可靠性。
示例性的，该条形孔可包括大通过尺寸段和小通过尺寸段，两者沿第二方向上连通形成条形孔，其中的小通过尺寸段的孔壁与定位柱的本体间隙配合；并配置为：位于安装位的条形孔通过大通过尺寸段与定位柱适配，以方便定位柱快速插装在条形孔中，位于预固定位的条形孔通过小通过尺寸段与定位柱适配，在第三方向形成对定位柱的限位。
基于第一方面，或第一方面的第一种实施方式，本申请实施例还提供了第一方面的第二种实施方式：限位部包括限位槽，预固定部为自支架的本体延伸形成的卡板，该卡板可沿第二方向插装于限位槽中，且在第二方向上限位槽的尺寸大于卡板的尺寸，以在预固定部切换至预固定位后形成限位。这样，组装时，可先将一侧卡板插装在相应的限位槽中，支架本体与待压元件压配后，再沿第二方向位移直至另一侧卡板也插装在相应的限位槽中，基于限位槽的尺寸大于卡板的尺寸的设计，使得支架两端侧的卡板均置于限位槽内，形成对支架本体的可靠限位。
基于第一方面，或第一方面的第一种实施方式，或第一方面的第二种实施方式，本申请实施例还提供了第一方面的第三种实施方式：限位部与固定构件一体成型，产品加工工艺性较好，能够有效制造成本。
在具体应用中，该固定构件可以为电子设备的壳体或主板。
在其他具体应用中，该固定构件还可以为固定在电子设备的壳体或主板上的构件。
本申请实施例第二方面提供了一种电子设备，包括通过BTB连接器与主板或副板连接的器件，该BTB连接器采用前述压合支架预固定结构进行预固定。
例如但不限于，该电子设备可以为手机、平板电脑、笔记本电脑、智能屏或学习机等。

具体实施方式
本申请实施例提供了一种压合支架预固定的解决方案，以实现牢靠的预固定效果和拆卸的便易性。在手机、平板电脑、笔记本电脑和智能屏等电子设备的具体应用上，基于不同组装工艺流程，能够使得待压元件的预装可靠性得以有效提升，同时可提升产线效率与装配质量。
不失一般性，本实施例以BTB连接器10作为描述主体，详细说明用于压合待压元件的压合支架预固定结构方案。图中所示的BTB连接器可实现将元件与FPC(Flexible Printed Circuit，柔性电路板)20的连接。应当理解，该BTB连接器10的功能结构及其连接关系的具体实现，非本申请的核心发明点所在，因此对本申请请求保护的压合支架预固定结构未构成实质性的限制。
在应用BTB连接器的电子设备中，为了适配BTB连接器的特点，利用压合支架30进行组装定位，能够确保其公母头之间的连接稳定性，进而防止连接松脱而导致出现功能失效等问题。实际组装时，该支架30的压合固定包括预固定和锁付固定两个操作环节。在压合支架组装工位，支架30与电子设备的壳体40之间为初步预固定，并在流转至锁付固定工位后，通过螺钉等紧固件(图中未示出)完成最终的锁付固定。
为了简化图面以清楚示意本方案的主要构成及连接关系，图中仅在支架30和壳体40上示出了该螺钉的安装孔(30a，40a)。
例如但不限于，在压合支架组装工位与螺钉锁付工位之间，配置有其他组装工位。可以理解的是，如果该压合支架30的预固定效果不佳，则会导致其在螺钉锁付工位出现翘起、偏位、掉落等不良。支架30的预固定结构的可靠性，直接影响产线效率与装配质量。
本实施中，以电子设备的壳体40作为适配于支架30的固定构件。这里的“固定构件”是指，在设备构成部分的装配关系下保持相对固定的结构，用于安装器件且无动态配合关系的部分，例如但不限于图中所示以电子设备1的壳体40。实际应用时，可根据相应电子设备的总体设计要求进行选择，
在其他具体实施中，基于实际受力情况，用于安装支架30的固定构件还可以为电子设备的主板。
另外，该固定构件还可以为固定在电子设备的壳体或主板上的构件，只要满足承载需求并兼顾相应固定构件的基础功能均可。
为了便于描述，针对该支架30与BTB连接器10适配关系，本文定义了三个方向：第一方向X为支架30所提供的压合作用力的方向，第二方向Y为支架30切换位置的滑动方向，第三方向Z为垂直于第一方向X和第二方向Y的方向；其中，压合作用于BTB连接器10的支架本体33部分，形成在第三方向Z与第二方向Y构成的平面内。
本申请实施例提供的压合支架预固定结构，其支架30的第二方向Y上的两端侧的预固定部(31、32)，壳体40上设置的两个限位部(41、42)。两个限位部形成在第一方向X上与支架相对的壳体40位置处，两个预固定部与两个限位部分别构建形成两个滑动限位副。
其中，两个滑动限位副均配置为：预固定部(31、32)可相对于相应的限位部(41、42)沿第二方向Y滑动，以切换于安装位和预固定位之间，限位部(41、42)可在第一方向上对位于预固定位的预固定部(31、32)形成限位。这里，“安装位”是指支架30扣合在BTB连接器10上的初始位置，此状态下，限位部还没有形成对相应预固定部的限位作用；“预固定位”是指支架30沿第二方向Y滑动位移后到达的适配位置，此状态下，限位部在第一方向X上形成了对相应预固定部的限位，完成该压合支架的可靠预固定。
两个滑动限位副中，至少一个滑动限位副的限位部在预固定部切换至预固定位后形成限位；也就是说，至少需要有一个限位关系是在预固定部切换至预固定位后才形成，满足压合支架的基础装配要求，便于实现支架30的组装或拆卸。
在具体实施时，可将两个滑动限位副均配置为切换至预固定位后，再形成上述限位。也就是说，两个预固定部(31、32)位于“安装位”时，两个限位部(41、42)均未在第一方向X上形成对相应预固定部的限位；支架30沿第二方向Y滑动位移，至两个预固定部(31、32)位于“预固定位”时，两个限位部(41、42)分别在第一方向X上形成对相应预固定部的限位。
其中，在支架30的本体33与BTB或固定构件之间设置有弹性件50，该弹性件50至少可在第一方向X上受压产生形变；换言之，该弹性件50需要在压合方向上提供复位作 用力至支架30，实际上，该弹性件50也可在其他方向上具备弹性变形的能力，而非局限于仅在第一方向X上具有受压产生形变的能力。
这样，预固定完成后，基于第一方向X上的受压形变，该弹性件50可施加作用力至支架本体33，并在两者间形成静摩擦力，由此，该支架30在垂直于第一方向X的平面内可保持无滑移状态，从而实现该压合支架30的可靠预固定。
应用本方案，压合支架预固定后具有较高的可靠性，有效规避了在工位流转过程中出现预固定失效的可能性。另外，操作者得以无工具执行预固定操作和逆向维修操作，且执行逆向维修拆卸操作时，不需要更换辅料和清胶。
需要说明的是，两个滑动限位副的具体功能实现可以采用不同的结构形式，同时，在第一方向X上建立的限位关系，两个滑动限位副可以是一者在预固定部切换至预固定位后形成，也可以是两者均在预固定部切换至预固定位后形成，下面分别以相应的实施例分别进行说明：
实施例一
请参见图1和图2，其中，图1为本实施例所述压合支架预固定结构的使用状态示意图，图2为图1中所示压合支架预固定结构的装配关系爆炸图。
如图所示，支架30两端侧的第一预固定部(31)和第二预固定部(32)，分别与壳体40上设置的第一限位部(41)和第二限位部(42)对应设置。请一并参见图3和图4，其中，图3为图1的俯视图，图4为图3的A-A剖视图。
本方案中，第一预固定部为自支架30的本体33延伸形成的卡板31，第一限位部包括限位槽41，该卡板31可沿第二方向Y插装于限位槽41中，并由限位槽41形成对卡板31的限位，也即构成一滑动限位副。第二预固定部包括长度沿第二方向Y设置的条形孔32，第二限位部42包括可沿第一方向X插装于条形孔32的定位柱42，在定位柱42的伸出端具有卡钩421，且该卡钩421沿第二方向朝向支架的本体33延伸形成，以在条形孔32切换至预固定位后形成限位，也即构成另一滑动适配副。
当然，在第二方向Y上限位槽41的尺寸大于卡板41的尺寸，以在条形孔32随支架30切换至预固定位后，卡板41依然置于限位槽41中。
支架30组装时，首先将其一端侧的卡板31斜插在限位槽41中，并将其另一端侧的条形孔32套装在定位柱42上，具体如图5所示的安装位；接下来，沿第一方向X按压支架30，采用泡棉制成的弹性件50受压形变，然后再按推支架30沿第二方向Y滑动，该过程中，卡板41在限位槽41中滑动位移，定位柱42在条形孔32中滑动位移，直至定位柱42端部的卡钩421扣合在支架本体33表面，具体如图6所示的预固定位，该图为图4的I部放大图。
支架预固定操作完成后，卸除人手组装下压力，泡棉受压缩形成的反作用力沿第一方向X作用于支架30，支架30的相应结构分别与定位柱42卡钩面和限位槽41内表面接触，并达到力的平衡；此时，两者间的静摩擦力能有效防止压合支架30滑移松脱，实现XYZ三个方向上的预固定。
本实施例中，弹性件50位于FPC20与支架30之间，以在提供形成上述静摩擦作用力的同时，起到压紧定位FPC20的作用。
该限位槽41和定位柱42可以与壳体40一体成型。可以理解的是，本方案中的限位槽41和定位柱42作为基础固定结构，非局限于形成在壳体40上。在其他实施例中，两者还可以设置在主板(图中未示出)等固定构件上。
当然还可以采用这样的设计，例如但不限于，限位槽和定位柱分别配置为独立构件(图中未示出)，再通过焊接等工艺固定在壳体或者主体上，同样可以达成基础固定结构的作用。
另外，该支架30的材料可以为不锈钢或铝合金。该包括不限于不锈钢、铝合金、工程塑胶(例如可以为ABS、PC或者PBT等)。该弹性件50可由泡棉制成，泡棉是塑料粒子发泡过的材料，具有有弹性、重量轻、快速压敏固定等特点；在实际应用中，该弹性件50可预先组装设置在BTB连接器10的补强体表面或者电子设备的壳体40表面，同样可以提供建立前述静摩擦力的作用力；例如但不限于采用粘接固定的方式，可避免装配操作间隔弹性件出现移位。或者，该弹性件50也可设置在支架本体33与BTB连接器10相对的表面上。
在其他实际应用中，弹性件50还可采用硅胶制成。硅胶主要成分是二氧化硅，具有化学性质稳定，热稳定性较好的特点。
实施例二
请参见图7，该图为本实施例所述压合支架预固定结构的示意图。为了清楚示出本方案与其他实施例的区别和联系，相同功能的构成或结构在图中以相同的标记进行示明。
如图所示，本实施例与实施例一的区别在于，本方案中的支架30两端侧的预固定部均为条形孔32a，相应地，壳体40上相应设置的两个限位部均为定位柱42a。
同样地，两个条形孔32a的长度沿第二方向Y设置，每个定位柱42a的伸出端具有卡钩421a，且该卡钩421a沿第二方向朝向支架的本体33延伸形成，以在条形孔32a切换至预固定位后形成限位，也即分别构成滑动适配副。
支架30组装时，两个定位柱42a可同时插装在其两端的条形孔32a中，按推支架30沿第二方向Y滑动，每个定位柱42a在相应的条形孔32a中滑动位移，直至卡钩421a扣合在支架本体33表面。这样，基于弹性件50的作用，利用静摩擦力能有效防止压合支架30滑移松脱，实现XYZ三个方向上的预固定。
本实施例不需要设计拆卸口，可节省架构空间。
实施例三
请参见图8，该图为本实施例所述压合支架预固定结构的示意图。为了清楚示出本方案与其他实施例的区别和联系，相同功能的构成或结构在图中以相同的标记进行示明。
如图所示，本实施例与实施例一和实施例二的区别在于，本方案中的支架30两端侧的预固定部均为卡板31a，相应地，壳体40上相应设置的两个限位部均为限位槽41a。
同样地，在第二方向Y上，每个限位槽41a的尺寸大于卡板41a的尺寸，一方面需要至少使得两个卡板41a均可处于与相应限位槽41a的初始安装位，另一方面需要满足两个 卡板41a随支架30切换至预固定位后，每个卡板41a依然置于相应的限位槽41a中，也即分别构成滑动适配副。
支架30组装时，首先将其第一端侧的卡板31a斜插在相应的限位槽41a中，并将其第二端侧的卡板31a与限位槽41a的槽口相对；再按推支架30沿第二方向Y滑动，随着第二端侧的卡板31a插入相应的限位槽41a，其第一端端的卡板31a依然置于限位槽41a中。基于弹性件50的作用，利用静摩擦力能有效防止压合支架30滑移松脱，实现XYZ三个方向上的预固定。
实施例四
请参见图9，该图示出了本实施例压合支架预固定结构的弹性件及其装配关系。为了清楚示出本方案与其他实施例的区别和联系，相同功能的构成或结构在图中以相同的标记进行示明。
如图所示，本实施例与实施例一区别在于，该弹性件50a为金属弹片结构，可在第一方向X上受压形变。支架预固定操作完成后，卸除人手组装下压力，该金属弹片可释放弹性变形能并沿第一方向X形成的反作用力，达到力的平衡后产生的静摩擦力，能有效防止压合支架30滑移松脱，实现XYZ三个方向上的预固定。
这里，金属弹片的自体结构非局限于图中所示的结构形态，只要能够至少在第一方向X上产生形变，均可辅以实现该支架30在三个方向上的可靠预固定。
在具体应用中，该金属弹片可一端固定在壳体或其他固定构件上，例如但不限于采用粘接固定的方式，另一端与支架30压抵的位置处可设计为弧状，以避免按推过程中产生不必要的滑动阻力。

  3. 根据权利要求2所述的压合支架预固定结构，其特征在于，所述条形孔的孔壁与所述定位柱的本体间隙配合。
  4. 根据权利要求2所述的压合支架预固定结构，其特征在于，所述条形孔包括大通过尺寸段和小通过尺寸段，且所述小通过尺寸段的孔壁与所述定位柱的本体间隙配合；并配置为：位于所述安装位的所述条形孔通过所述大通过尺寸段与所述定位柱适配，位于所述预固定位的所述条形孔通过所述小通过尺寸段与所述定位柱适配。
  5. 根据权利要求1所述的压合支架预固定结构，其特征在于，所述限位部包括限位槽，所述预固定部为自所述支架的本体延伸形成的卡板，所述卡板可沿第二方向插装于所述限位槽中，且在第二方向上所述限位槽的尺寸大于所述卡板的尺寸，以在所述预固定部切换至所述预固定位后形成所述限位。
  6. 根据权利要求1至5中任一项所述的压合支架预固定结构，其特征在于，所述弹性件为泡棉、硅胶或金属弹片。
  7. 根据权利要求1至6中任一项所述的压合支架预固定结构，其特征在于，所述弹性件设置在所述待压元件的表面或者电子设备的壳体表面。
  8. 根据权利要求1至7中任一项所述的压合支架预固定结构，其特征在于，所述限位部与所述固定构件一体成型。
  9. 根据权利要求1至8中任一项所述的压合支架预固定结构，其特征在于，所述固定构件为电子设备的壳体或主板，或者为固定在所述电子设备的壳体或主板上的构件。
  10. 根据权利要求1至9中任一项所述的压合支架预固定结构，其特征在于，所述压合支架的材料为不锈钢或铝合金。
  11. 一种电子设备，其特征在于，包括通过BTB连接器与主板或副板连接的器件，所述BTB连接器采用权利要求1至10中任一项所述的压合支架预固定结构进行预固定。
