The extension mechanism will drive the unlocking device to extend synchronously during the extension process. The insertion end 21 of the unlocking lever 2 will be connected to the unlocking matching piece by inserting, so as to drive the unlocking lever 2 to rotate to drive the unlocking matching piece. Rotate to realize unlocking or locking of the locking mechanism. After the operation is completed, the retraction of the extension mechanism will drive the insertion end 21 and the unlocking matching piece to be disconnected from each other, thereby achieving separation. The connection and disconnection are very convenient, the stability is high, and the structure is simple.

***端21的外表面具有至少一个抵靠面211，电池托架上设有解锁匹配件，解锁匹配件与锁止机构连接，***端21用于***解锁匹配件内，且抵靠面211与解锁匹配件的内壁面相匹配，以实现带动解锁匹配件旋转。解锁杆2在旋转时，通过抵靠面211与解锁匹配件的内壁面相匹配，使得抵靠面211将会对解锁匹配件施加作用力并驱动解锁匹配件旋转，从而带动锁止机构锁止机构转动以解锁或锁止电池箱。通过抵靠面211对解锁匹配件的内壁面施加作用力来带动解锁匹配件旋转，旋转稳定性高。在本实施中，抵靠面211的数量为四个，四个抵靠面211之间相互围成方形结构，旋转稳定性更高。当然，在其他实施例中，抵靠面211的数量可以不作限定，多个抵靠面211之间相互围成的形状只要是非圆形均可带动解锁匹配件旋转。The outer surface of the inserting end 21 has at least one abutting surface 211, the battery bracket is provided with an unlocking matching piece, the unlocking matching piece is connected with the locking mechanism, the inserting end 21 is used to insert the unlocking matching piece, and the abutting surface 211 is connected to the The inner wall surface of the unlocking matching piece is matched to realize the rotation of the unlocking matching piece. When the unlocking lever 2 rotates, the abutting surface 211 matches the inner wall surface of the unlocking matching piece, so that the abutting surface 211 will exert a force on the unlocking matching piece and drive the unlocking matching piece to rotate, thereby driving the locking mechanism of the locking mechanism Turn to unlock or lock the battery box. The abutting surface 211 exerts a force on the inner wall surface of the unlocking matching piece to drive the unlocking matching piece to rotate, and the rotation stability is high.

由于***端21的外表面为非圆形结构，且需要抵靠面211与解锁匹配件的内壁面相匹配，使得解锁杆2的***端21准确对位***。解锁杆2中朝向驱动机构1的一端具有连接部22，连接部22外周面上具有腰型孔221，连接部22通过腰型孔221连接于驱动机构1。解锁杆2通过连接部22与驱动机构1相互连接，腰型孔221沿连接部22外周面上延伸，使得连接部22在安装连接时能够沿其周向方向旋转调节，从而可以调节解锁杆2，使得***端21***至解锁匹配件内以实现抵靠面211与解锁匹配件的内壁面相匹配。Since the outer surface of the insertion end 21 is a non-circular structure, and the abutting surface 211 needs to be matched with the inner wall surface of the unlocking matching piece, the insertion end 21 of the unlocking lever 2 is inserted accurately. One end of the unlocking lever 2 facing the driving mechanism 1 has a connecting portion 22, and the outer peripheral surface of the connecting portion 22 has a waist-shaped hole 221, and the connecting portion 22 is connected to the driving mechanism 1 through the waist-shaped hole 221.

解锁杆2与解锁匹配件之间不仅在解锁杆2的周向上需要旋转调节，解锁杆2与解锁匹配件之间还存在解锁杆2的轴线与解锁匹配件的轴线对位不准确的情况，即存在有微小的位置偏差而不在同一直线上。为了达到解锁装置能够适应对位不准确的情况。如图4所示，连接单元3包括可径向扭转的第一弹性件31，第一弹性件31的两端分别连接于驱动机构1和解锁杆2，且第一弹性件31以适应解锁杆2的径向位移。在驱动机构1固定不动的情况下，通过第一弹性件31能够在径向方向上位移，使得解锁杆2能够匹配***至解锁匹配件内，实现解锁装置在解锁或者锁止的过程中稳定性更高。The unlocking lever 2 and the unlocking matching part not only need to be rotated and adjusted in the circumferential direction of the unlocking lever 2, but also between the unlocking lever 2 and the unlocking matching part, the alignment of the axis of the unlocking lever 2 and the axis of the unlocking matching part is not accurate. That is, there is a slight position deviation that is not on the same straight line. In order to achieve the unlocking device can adapt to the situation of inaccurate alignment. As shown in FIG. 4, the connecting unit 3 includes a first elastic member 31 that can be twisted in a radial direction. 2 radial displacement. When the driving mechanism 1 is fixed, the first elastic member 31 can be displaced in the radial direction, so that the unlocking lever 2 can be inserted into the unlocking matching member, so that the unlocking device is stable during the unlocking or locking process.

Two ends of the first elastic member 31 are respectively connected to the first connecting sleeve 32 and the second connecting sleeve 33, and the unlocking lever 2 is connected to the first connecting sleeve 32, The driving mechanism 1 is connected to the second connecting sleeve 33. The driving mechanism 1, the first elastic member 31, and the unlocking rod 2 are connected in series with each other through the first connecting sleeve 32 and the second connecting sleeve 33 to ensure that the unlocking device is connected in the axial direction and rotates around its axis, with higher stability, and Easy to install and connect. The first elastic member 31 may be a flexible shaft, and the material of the first connecting sleeve 32 and the second connecting sleeve 33 may be metal.

连接单元3滑设于驱动机构1，以带动解锁杆2沿靠近驱动机构1的方向。解锁装置在解锁或者锁止的过程中，需要解锁杆2的***端21准确对位***解锁匹配件内，在***到位时，解锁杆2将会与解锁匹配件相互抵靠，使得解锁匹配件将会对解锁杆2施加沿靠近驱动机构1的方向的作用力，通过连接单元3滑设于驱动机构1，使得解锁杆2在受到沿靠近驱动机构1的方向的作用力时将会带动连接单元3在驱动机构1上移动，有效避免了刚性连接而造成结构的损坏，安全稳定性更高，使用寿命长。当然，解锁杆2的***端21在没有***至解锁匹配件内时，解锁匹配件也就不会对解锁杆2施加沿靠近驱动机构1的方向的作用力。The connecting unit 3 is slidably arranged on the driving mechanism 1 to drive the unlocking lever 2 in a direction approaching the driving mechanism 1. During the unlocking or locking process of the unlocking device, the insertion end 21 of the unlocking lever 2 needs to be accurately aligned and inserted into the unlocking matching piece.

The detection block 5 is connected to the connecting unit 3, and when the unlocking lever 2 is aligned and inserted into the unlocking matching piece, the detection block 5 and the connecting unit 3 will be driven to move in a direction close to the driving mechanism 1. In this embodiment, in the initial state, the detection block 5 is not located in the detection area of the detection unit 4. When the unlock lever 2 is inserted into the unlocking matching piece, the detection block 5 will move to the detection area of the detection unit 4, and the detection If the unit 4 can detect that the detection block 5 has moved to the detection area, it means that the unlocking lever 2 has entered the unlocking matching piece and reached the unlocking position; when the detection unit 4 has not detected that the detection block 5 has moved to the detection area, it means that the unlocking lever 2 is not aligned To unlock the matching parts, the unlocking lever can be controlled in time to stop moving.
