如图1至8所示，本实施例提供了一种锁紧装置，包括基座1、压块2和驱动单元3，压块2枢接于基座1；驱动单元3包括驱动源和连杆组件32，驱动源固设于基座1，连杆组件32连接于压块2与驱动源之间，驱动源驱动连杆组件32运动以带动压块2绕与基座1的枢接轴转动，以使压块2选择性地压紧或脱离待锁紧件。
驱动源驱动连杆组件32带动压块2动作，相比于现有技术，提高了锁紧力以及与其他设备的兼容性；驱动源固设于基座1，使得锁紧装置的结构更加紧凑，占用空间小。
可选地，驱动源包括弹性件以及解锁单元，弹性件被配置为提供压紧并保持对待锁紧件的压紧力，解锁单元用于抵消弹性件的压紧力并对弹性件进行压缩，以使压块2能够脱离待锁紧件。示例性地，弹性件为压缩弹簧；当然，弹性件还可以为可压缩的气囊等能产生弹性形变并自动复位的其他结构。
弹性件被配置为提供压紧并保持对待锁紧件的压紧力，解锁单元用于抵消弹性件的压紧力并对弹性件进行压缩，以使压块2能够脱离待锁紧件，相比于采用气缸作为驱动源，解决了失去气源时锁紧装置失去锁紧作用的问题，消除了安全隐患。
本实施例中，驱动源具体为制动气室31，制动气室31的结构为现有技术，在此不再赘述。需要说明的是，弹性件为制动气室31内部自带的弹簧，解锁单元为气源(未图示)及相关管路附件，制动气室31的进气口与气源连接，在气源向制动气室31内通入一定压力的气体时，弹性件在气体压力的作用下被压缩，此时，制动气室31的推杆311驱动连杆组件32带动压块2转动，以使压块2脱离待锁紧件；在气源停止向制动气室31内通入压力气体时，弹性件自动复位，此时，制动气室31的推杆311驱动连杆组件32带动压块2转动，以使压块2压紧待 锁紧件，如此设置，即使在气源意外中断时，锁紧装置依然能对待锁紧件起到锁紧作用，安全性更高。
需要说明的是，本实施例中，制动气室31固设于基座1，制动气室31的推杆311与制动气室31的压缩弹簧连接，推杆311可以在压缩弹簧的弹力作用下伸出，提供驱动力，同时，压缩弹簧产生弹性形变，使得推杆311可以在±6°的角度范围内摆动，适应性强。
可选地，连杆组件32设有两个，且两个连杆组件32对称设于压块2的两侧，驱动源与两个连杆组件32分别连接，以通过驱动源驱动两个连杆组件32同步动作，可提高锁紧装置整体承载力及刚度，进而提高锁紧力，延长使用寿命。
可选地，锁紧装置还包括转接推杆4，转接推杆4包括第一转接端41和与两个连杆组件32一一对应设置的第二转接端42，第一转接端41与驱动源的动作端固定连接，本实施例中驱动源的动作端即为制动气室31的推杆311，第二转接端42与对应的连杆组件32枢接，以实现通过一个转接推杆4驱动两个连杆组件32同步动作。
本实施例中，转接推杆4呈U形结构，第一转接端41设置于U形结构的底端，，第二转接端42设置于U形结构的两端顶部。U形结构的转接推杆4，与两个连杆组件32匹配设置，可使连杆组件32传动更平稳，还可提高锁紧装置整体承载力及刚度，进而提高锁紧力。
具体地，转接推杆4包括依次连接的第一杆体、第二杆体和第三杆体，第一杆体和第三杆体相对设置；第一转接端41设置在第二杆体的中部，两个第二转接端42分别设置在第一杆体远离第二杆体的一端和第三杆体远离第二杆体的一端。第一杆体、第二杆体和第三杆体为一体成型的U形结构。
可选地，连杆组件32包括第一连杆321和第二连杆322，第一连杆321包括呈三角形轨迹依次设置的第一端3211、第二端3212和第三端3213，第一端3211与基座1枢接，第二端3212与对应的第二转接端42枢接；第二连杆322的一端与第三端3213枢接，另一端与压块2枢接。相比于现有技术，本实施例中，利用制动气室31驱动连杆组件32带动压块2转动，且制动气室31固设于基座1，具有简化结构，节省占用空间的作用。
可选地，驱动单元3还包括第一连接轴33，第一连接轴33的两端分别穿过两个连杆组件32的第二连杆322的一端后，与两个连杆组件32的第一连杆枢接。利用第一连接轴33连接两个连杆组件32，一方面保证了两个连杆组件32的同步性，另一方面提高了整体结构强度和承载力。
可选地，驱动单元3还包括第二连接轴34，第二连接轴34穿设于压块2，且第二连接轴34的两端分别与两个连杆组件32的第二连杆322枢接，不仅工艺性好，便于第二连杆322与压块2装配，还能提高第二连杆322与压块2的连接稳固性。
本实施例中，第一连杆321为三角块状结构，第一连杆321设有呈三角形布置的第一轴孔3214、第二轴孔3215和第三轴孔3216，其中，第一轴孔3214中穿设有第一销轴3217，第一连杆321通过第一销轴3217与基座1枢接；第二轴孔3215中穿设有第二销轴3218，第一 连杆321通过第二销轴3218与转接推杆4对应的第二转接端42枢接；第一连接轴33穿设于两个第二连杆322并与两个第二连杆322枢接，第一连接轴33的两端分别穿设于两个第一连杆321的第三轴孔3216中。
第二连杆322的两端分别设有第四轴孔3221和第五轴孔3222，第一连接轴33穿设于第四轴孔3221中，第二连接轴34穿设于第五轴孔3222中。
为了便于锁紧装置装配并提高布局合理性，基座1包括与两个连杆组件32一一对应设置的支撑架11，第一端3211枢接于对应的支撑架11。
本实施例中，压块2的尾端设有尾端轴孔21，尾端轴孔21中穿设有安装销轴23，安装销轴23的两端分别与两个支撑架11枢接，压块2通过安装销轴23与两个支撑架11枢接，以对压块2提供稳定的支撑。压块2的中部设有中部轴孔22，第二连接轴34穿设于中部轴孔22中。
可选地，支撑架11为倒U形结构，转接推杆4的第二转接端42自对应的支撑架11的U形开口中伸出与对应的第一连杆321的第二端3212枢接。换言之，两个连杆组件32的第一连杆321分别位于对应的支撑架11外侧，相比于将两个第一连杆321设于两个支撑架11之间而言，可缩短压块2的安装销轴23的长度，具有提高整体结构强度，减少占用空间的作用。
可选地，支撑架11与基座1之间设有加强连接结构，以保证二者的连接稳固性，提高支撑架11结构强度。
可选地，基座1包括定位座体12和连接于定位座体12一侧的安装座体13，定位座体12与安装座体13之间呈夹角设置，且夹角为钝角。两个支撑架11均固设于安装座体13。可选地，驱动源固设于安装座体13背离压块2的一侧，且驱动源的轴线与安装座体13垂直。本实施例中，驱动源为制动气室31，换言之，制动气室31倾斜设于安装座体13背离压块2的一侧，相比于现有技术，具有减少占用压块2与安装座体13之间的空间的作用，不妨碍待锁紧件布局。
进一步地，安装座体13包括相对设置的第一承载端面和第二承载端面，连杆组件32设置在第一承载端面上，驱动源的至少部分设置在第二承载端面上。
具体地，安装座体13包括：承载板体，第一承载端面和第二承载端面分别设置在承载板体上，承载板体与定位座体12的端部连接，承载板体与定位座体12之间具有夹角；防护板体，防护板体为两个，两个防护板体分别设置在承载板体的两端，两个防护板体之间形成安装空间，驱动源的至少部分位于安装空间内。
定位座体12包括：依次连接的第一座体、第二座体和第三座体，第一座体和第三座体与安装座体之间分别具有夹角；第一座体与第三座体相对设置，以在第一座体、第二座体和第三座体之间围成减重空间。
可以理解的是，安装座体13开设有通孔，制动气室31的推杆311穿设于该通孔，并可在该通孔中伸缩，达到驱动压块2转动的目的。
为了达到减重及减少用料的目的，本实施例中，定位座体12上开设有减重槽121。
可选地，基座1设有加强结构，具有提高基座1结构强度的作用。示例性地，定位座体12和安装座体13上均设有加强结构。
可选地，定位座体12背离安装座体13的一侧设有安装结构，利用安装结构可将定位座体12固定安装于车辆的换电底座200等结构上，适配性高。
示例性地，本实施例的锁紧装置的工作过程为：
当制动气室31的推杆311向外伸出时，推杆311可在±6°的角度范围内摆动，可驱动转接推杆4带动两个第一连杆321绕第一销轴3217转动，同时，第一连杆321带动第二连杆322转动，第二连杆322带动压块2绕安装销轴23转动，直至压块2的自由端压紧待锁紧件，达到锁紧待锁紧件的目的。
当制动气室31的推杆311向内缩回时，驱动转接推杆4带动两个第一连杆321绕第一销轴3217转动，同时，第一连杆321带动第二连杆322转动，第二连杆322带动压块2绕安装销轴23转动，直至压块2的自由端脱离待锁紧件，实现待锁紧件解锁。
本实施例还提供了一种车辆，包括如上述锁紧装置。通过应用上述锁紧装置，解除了车辆行驶过程中对气源的依赖，安全性更高。
可选地，车辆还包括换电电池100和换电底座200，本实施例中，换电电池100即为待锁紧件；驱动源比如制动气室31能驱动压块2绕其与基座1的枢接轴转动，以使压块2能选择性地将换电电池100压紧于换电底座200。相比于现有技术，本实施例的锁紧装置不依赖气源，极大地降低了换电电池100意外松脱的风险，安全性更高。
注意，上述仅为本申请的较佳实施例及所运用技术原理。本领域技术人员会理解，本申请不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本申请的保护范围。因此，虽然通过以上实施例对本申请进行了较为详细的说明，但是本申请不仅仅限于以上实施例，在不脱离本申请构思的情况下，还可以包括更多其他等效实施例，而本申请的范围由所附的权利要求范围决定。
