The invention relates to the technical field of electric automobiles, in particular to a locking mechanism. The locking mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod and a driving piece. The second connecting rod is hinged to the first connecting rod, the third connecting rod is hinged to the second connecting rod, the fourth connecting rod is hinged to the first connecting rod, the fourth connecting rod is hinged to the third connecting rod, and hinge points among the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod and the driving part are different. The third connecting rod and the fourth connecting rod are driven to rotate, so that the free end of the fourth connecting rod presses and fixes the workpiece. According to the structure, the output force of the driving part is amplified through the second connecting rod, the third connecting rod and the fourth connecting rod, the cost of the locking mechanism is reduced, the stability of locking workpieces is improved, meanwhile, the locking mechanism is simple in structure and low in requirement for application space, and the compatibility of the locking mechanism is enhanced.
本发明涉及电动汽车技术领域,尤其涉及一种锁紧机构。该锁紧机构包括第一连杆、第二连杆、第三连杆、第四连杆以及驱动件。第二连杆与第一连杆铰接,第三连杆与第二连杆铰接,第四连杆与第一连杆铰接,且第四连杆与第三连杆铰接,第一连杆、第二连杆、第三连杆、第四连杆以及驱动件之间的每个铰接点并不相同,驱动件用于驱动第二连杆转动,带动第三连杆以及第四连杆转动,使第四连杆的自由端压紧工件并固定工件。该结构通过第二连杆、第三连杆以及第四连杆将驱动件的输出力放大,有利于降低锁紧机构成本,且提高锁固工件的稳定性,同时,该锁紧机构结构简单,对应用空间的要求低,增强锁紧机构的兼容性。
