Referring to Fig. 6 to Fig. 9, chute includes first passage 5.1, second channel 5.2 and third channel 5.3, first
Passage 5.1 and third channel 5.3 are longitudinally disposed and be parallel to each other, second channel 5.2 horizontally set, and second channel 5.2 and
One passage 5.1 connects with third channel 5.3 head and the tail.
During vehicle body lower house 3 is fastened with battery lower house 2, first polished rod 4.2 is sequentially passed through battery lower casing
Body 2 and vehicle body lower house 3, be placed in nut 5, then attempts leading to projection 4.2.1 alignment first by the head of swivel bolt 4
Road 5.1, and by the head of promotion bolt 4, protruding 4.2.1 is pushed into the farthest of first passage 5.1, now swivel bolt 4,
Make protruding 4.2.1 enter second channel 5.2, and make protruding 4.2.1 rotate to second channel 5.2 by the head of swivel bolt 4
Farthest and with step 5.4 clamping, now protruding 4.2.1 is directed at third channel 5.3, then the head by promotion bolt 4
Projection 4.2.1 is released nut 5 end face along third channel 5.3；After polished rod 4.2 is pushed out nut 5 end face certain altitude, stud
4.1 initially enter in nut 5, and make stud 4.1 fasten with nut 5 by the head of swivel bolt 4, to complete battery lower house
2 fixing with vehicle body lower house 3.
During battery bag is dismantled, need also exist for reversely rotating bolt 4 making stud 4.1 remove nut 5, work as stud
After 4.1 removal nut 5 certain distances, protruding 4.2.1 touches the end face of nut 5, makes projection by the head of swivel bolt 4
4.2.1 it is directed at third channel 5.3, and makes protruding 4.2.1 enter at third channel 5.3 to step 5.4, although now bolt 4
Relieve with nut 5 and threaded, but coordinating by protruding 4.2.1 and step 5.4, make battery bag be still within a kind of suspension
State, it is ensured that battery will not come off because fixing bolt 4 gradually decreases during wrapping in demounting bolt 4, treats all
After the threaded releasing of bolt, then make protruding 4.2.1 rotate through second channel 5.2 by the head of swivel bolt 4, and continue
Exit along first passage 5.1, to complete the dismounting of bolt 4.
It should be noted that first passage 5.1 and third channel 5.3 are longitudinally disposed and be parallel to each other, wherein, longitudinally refer to
It is that first passage 5.1 and third channel 5.3 are opened on the inwall in the second chamber 5.5 each along the axis direction of polished rod 4.2,
Two passages 5.2 are opened on the inwall in the second chamber 5.5 along the direction of the axis being perpendicular to polished rod 4.2.
Further, the length of polished rod 4.2 is more than the length of stud 4.1, it is ensured that when installing bolt 4, protruding
4.2.1, after passing nut 5 end face along third channel 5.3, a certain distance between stud 4.1 and nut 5, can be there is, this section away from
From at least above protruding 4.2.1 thickness along polished rod 4.2 axis direction, in order to adjust the angle of bolt 4, it is to avoid protruding
4.2.1 interfere with third channel 5.3 and cause bolt 4 to rotate.
Further, the second chamber 5.5 is matched in clearance with coordinating between polished rod 4.2, in order to polished rod 4.2 is in the second chamber 5.5
In can rotate freely.
Further, the securing member assembly with ledge structure that this utility model embodiment provides, also include for pressing
The pad 4.3 of tight plate, pad 4.3 is set on stud 4.1, and supports the head at bolt 4, in order to compress vehicle body lower casing
Body 3 and battery lower house 2.
Further, the quantity of protruding 4.2.1 can be two, is arranged on polished rod 4.2 with the axisymmetrical of polished rod 4.2
On.
It should be noted that the quantity of protruding 4.2.1 is not only limited to two, it is also possible to be three or multiple, specifically
Quantity to be configured, to this present embodiment not according to the stability that bolt 4 load-bearing and protruding 4.2.1 coordinate with step 5.4
It is construed as limiting.
Further, protruding 4.2.1 can be positioned close on the polished rod 4.2 sidewall away from one end of stud 4.1.
It will be appreciated by persons skilled in the art that the shape of protruding 4.2.1 can be arranged to multiple, it is preferred that convex
Playing the side being used on 4.2.1 coordinating with first passage 5.1 and third channel 5.3 is arc-shaped, in order to it is each with chute logical
Slip between road, alleviates the problem that protruding 4.2.1 interferes with each interchannel.
The securing member assembly with ledge structure that this utility model embodiment provides, by chute, step and projection
Arrange, evaded battery and wrapped in the risk come off in disassembly process, improve safety when battery wraps in dismounting.
Of the present utility model structure, feature and action effect are described in detail above according to graphic shown embodiment, with
Upper described it is only preferred embodiment of the present utility model, but this utility model is not to limit practical range shown in drawing, every depend on
