本发明涉及一种锁止机构,包括锁定壳体、锁定连接件、顶升装置和锁定球;所述锁定连接件套设于所述锁定壳体端部,所述锁定壳体端部设有锁定孔,所述锁定球设于所述锁定壳体且能够通过锁定孔部分地伸出,当所述锁定球部分伸出所述锁定孔时,所述锁定壳体和所述锁定连接件相对锁定;所述顶升装置包括顶出块和顶升杆,所述顶出块用于将所述锁定球顶出所述锁定孔,所述顶出块具有与所述锁定球配合的顶出槽,所述顶升装置在所述锁定位置和所述解锁位置之间移动过程中,所述锁定球与所述顶出槽为线接触配合。本发明提供了一种变形小、结构稳定的锁止机构。解决了现有技术中挤出锁定孔的小球容易变形,导致锁止不顺畅甚至锁止失败的技术问题。

    A locking device used for battery exchange, comprising an upper locking mechanism (10) and a lower locking mechanism (20); the upper locking mechanism (10) comprises an upper lock body (102) and a floating block (103), the floating block (103) being provided inside the upper lock body (102), and an opening and a first inner cavity which communicate with each other being provided on the floating block (103); the lower locking mechanism (20) may penetrate the opening and extend into the first inner cavity, and the lower locking mechanism (20) comprises locking balls (201), an ejection block (202), a lower lock body (203) and an ejection rod (205), the lower lock body (203) being a hollow structure, and the locking balls (201) being provided in the lower lock body (203). The lower lock body (203) is provided with a hole opening (2033), and at least part of the locking balls (201) may extend out of the hole opening (2033) and abut against the floating block (103). The ejection block (202) is connected to the locking balls (201) and the ejection rod (205), and the ejection rod (205) is used to control the position of the ejection block (202) so as to eject the locking balls (201) out of the hole opening (2033) or to keep the locking balls (201) inside the lower lock body (203). Further provided is a vehicle. By means of the ejection rod (205) driving the locking balls (201) to move between an unlocked position and a locked position, and the locking balls (201) and the ejection block (202) being in line contact fit, the problem of stress concentration at a contact point between the locking balls (201) and the ejection block (202) is greatly reduced.
