Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio
Same or similar element or the element of same or like function is represented to same or similar label eventually.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining this utility model, and can not be construed to restriction of the present utility model.

Bolt assembly in the structural representation of bolt, the structure of nut in the bolt assembly that Fig. 5 provides for this utility model embodiment
Schematic diagram.
Referring to Fig. 3 to Fig. 5, this utility model embodiment provides a kind of bolt assembly, including bolt 4 and nut
5;Wherein, bolt 4 includes stud 4.1 and polished rod 4.2, and the external diameter of polished rod 4.2 is less than the external diameter of stud 4.1, and polished rod 4.2 sets to be put
There is protruding 4.2.1;Nut 5 includes the first chamber 5.1 and the second chamber 5.2, and the first chamber 5.1 is provided with the interior spiral shell coordinated with stud 4.1
Stricture of vagina;Second chamber 5.2 is provided with the chute 5.3 for coordinating with protruding 4.2.1, and chute 5.3 is vertically opened in the second chamber 5.2
On inwall.
The state diagram of bolt pre-installation in the bolt assembly that Fig. 6 provides for this utility model embodiment, Fig. 7 be this practicality newly
The bolt assembly protrusions that type embodiment provides enters the state diagram of chute, the bolt that Fig. 8 provides for this utility model embodiment
In assembly, stud enters the state diagram before nut, when in the bolt assembly that Fig. 9 provides for this utility model embodiment, bolt is tightened
State diagram.
Referring to Fig. 6 to Fig. 9, during vehicle body lower house 3 is fastened with battery lower house 2, first by polished rod
4.2 sequentially pass through battery lower house 2 and vehicle body lower house 3, are placed in nut 5, then will by swivel bolt head 4.4 trial
Protruding 4.2.1 is directed at chute 5.3, and by promoting bolt head 4.4 that protruding 4.2.1 releases the end of nut 5 along chute 5.3
Face;After polished rod 4.2 is pushed out the end face certain altitude of nut 5, stud 4.1 initially enters in nut 5, and passes through swivel bolt
Head 4.4 makes stud 4.1 fasten with nut 5, to complete the fixing of battery lower house 2 and 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 swivel bolt head 4.4
4.2.1 chute 5.3 is avoided, so that protruding 4.2.1 is connected to the end face of nut 5, although now bolt 4 and nut 5 relieve spiral shell
Stricture of vagina connects, but owing to protruding 4.2.1 is connected to the end face of nut 5, makes battery bag be still within a kind of suspension status, it is ensured that electricity
Pond will not come off because fixing bolt gradually decreases during wrapping in demounting bolt 4, and that treats all bolts is threaded
After releasing, then make protruding 4.2.1 rotate to chute 5.3 position by swivel bolt head 4.4, and continue to exit along chute 5.3,
To complete the dismounting of bolt 4.
Further, the second chamber 5.2 is matched in clearance with coordinating between polished rod 4.2, in order to polished rod 4.2 is in the second chamber 5.2
In can rotate freely.
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 chute 5.3, can there is a certain distance between stud 4.1 and nut 5, this segment distance is extremely
Few more than 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 with
Chute 5.3 interferes and causes bolt 4 to rotate.
Further, the bolt assembly that this utility model embodiment provides, also include the pad 4.3 for compressing plate,
Pad 4.3 is set on stud 4.1, and supports at bolt head 4.4, in order to compress vehicle body lower house 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
Stability when quantity to be connected to nut 5 end face according to bolt 4 load-bearing and protruding 4.2.1 is configured, to this this enforcement
Example is not 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 chute 5.3 is arc-shaped, in order to the slip between itself and chute 5.3, alleviates projection
4.2.1 the problem of clamping stagnation and between chute 5.3.
The bolt assembly that this utility model embodiment provides, by chute 5.3 and the setting of protruding 4.2.1, has evaded electricity
Pond wraps in the risk come off in disassembly process, improves 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
The change made according to conception of the present utility model, or it is revised as the Equivalent embodiments of equivalent variations, still without departing from description and figure
Show contained spiritual time, all should be in protection domain of the present utility model.
