It is equipped with air intake interface 111, waterway inlet interface 112 and hydrogen outlet interface 113.By these interfaces introduce air,
Hydrogen or water, to guarantee that the pile in pile encapsulating housing 101 is reliable for operation.Further, air intake interface 111 and water route
Ingress interface 112 is positioned close to fixed 103 position of bracket of driving motor, and it is solid that hydrogen outlet interface 113 is provided close to retarder
102 position of fixed rack.
Fig. 4 shows the structural schematic diagram of the pile encapsulating housing 101 of the pile frame 100 of one embodiment of the invention.
Fig. 5 is the assembling schematic diagram of Fig. 4.As shown, pile encapsulating housing 101 is a cuboid.Pile encapsulating housing 101 includes frame
Frame ontology 114, frame cover board 115 and chassis base 116.Frame cover board 115 is set to the top of frame body 114 and and frame
The top of ontology 114 seals cooperation, and chassis base 116 is set to the bottom of frame body 114 and the bottom with frame body 114
Sealing cooperation.
Fig. 6 is the assembling schematic diagram of the frame body 114 in Fig. 5.Preferably, frame body 114 includes first enclosed
Coaming plate 117, the second coaming plate 118, the first side plate 119 and the second side plate 120.Wherein, the end face of 119 two sides of the first side plate passes through fixed
Position pin 121 and the end surface of the first coaming plate 117 and the second coaming plate 118 are fixed.The end face of second side plate, 120 two sides passes through positioning
Pin 121 and another end surfaces of the first coaming plate 117 and the second coaming plate 118 are fixed.In general, the first coaming plate 117 and the second coaming plate 118
Size it is essentially identical, position is opposite；The size of first side plate 119 and the second side plate 120 is essentially identical, and the two position is opposite.
First coaming plate 117, the second coaming plate 118, the first side plate 119 and the second side plate 120 enclose a hollow frame body 114.Edge
The length of the circumferential direction of frame body 114, the first coaming plate 117 and the second coaming plate 118 is greater than the first side plate 119 and second side
The length of plate 120.The assembly of frame body 114 can carry out location and installation by positioning pin 121, and improve frame body 114
Strength and stiffness.
Preferably, pile frame 100 further includes bolt 122.It is opened between the inner wall and end face of the outer rim of the first side plate 119
Equipped with mounting hole 123, counterbore 124 is offered in 117 outer fringe surface of the first coaming plate.The mounting hole 123 and counterbore 124 are corresponding, spiral shell
Bolt 122 penetrates mounting hole 123 and protrudes into counterbore 124, and the two is threadedly engaged fixation.Similarly, in the outer fringe surface of the second coaming plate 118
Counterbore 124 corresponding with mounting hole 123 can be opened up, is fastened in order to which bolt 122 cooperates.It is readily comprehensible, the second side plate 120
Corresponding structure can also be used.Frame body 114 further improves its strength and stiffness in the fastening effect of bolt 122.
By the positioning action of positioning pin 121, assembles bolt 122 more convenient, be coupled without other tooling.As an example
Rather than limit, hexagon socket head cap screw can be used in bolt 122, in order to install.Further, since using 122 knot of positioning pin 121 and bolt
Structure is fixed, the first coaming plate 117, the second coaming plate 118, the first side plate 119 and the second side plate 120 thickness can be controlled in 6mm or so,
In favor of the welding in later period.Likewise, positioning pin 121 and 122 structure of bolt can be adapted for frame body 114 and frame
It is fixed between cover board 115, and being connected and fixed applied to frame body 114 and chassis base 116.

It is welded and fixed between chassis base 116 using friction stir welding method.Specifically, due to using positioning pin 121 and bolt 122
Structure is fixed, so that the first coaming plate 117, the second coaming plate 118, the first side plate 119, the second side plate 120 and frame cover board 115
It is can be controlled in 6mm or so with the thickness of chassis base 116, then the most economic, sexual valence is welded and fixed using friction stir welding method
Than high.
The basic manufacturing process of pile encapsulating housing 101 is specifically described below in conjunction with fig. 4 to fig. 6.
Whole rectangular box is divided into 6 pieces of plates first and processed by the scheme of manufacture pile encapsulating housing 101, respectively
It is the first coaming plate 117, the second coaming plate 118, the first side plate 119, the second side plate 120, frame cover board 115 and chassis base 116.This
Sample design is avoided integrally to be machined using aluminium ingot, can save great number fee of material and great number processing charges.
Then, location hole and counterbore 124 are opened up on the first coaming plate 117 and the second coaming plate 118, in 119 He of the first side plate
Mounting hole 123 and location hole are opened up on second side plate 120, is inserted into positioning pin 121 between corresponding location hole to fix first
The installation site of coaming plate 117, the second coaming plate 118, the first side plate 119, the second side plate 120.Then installation is penetrated using bolt 122
Corresponding counterbore 124 is simultaneously protruded into hole 123, is threadedly engaged fastening with counterbore 124.It can be pile encapsulating housing by this kind of structure
101 provide enough strength and stiffness, and can be welded in assembling process without tool locating.Further, by
In using positioning pin 121 positioning and 122 clamping structure of bolt so that the first coaming plate 117, the second coaming plate 118, the first side plate 119,
The thickness of second side plate 120, frame cover board 115 and chassis base 116 can become thinner, and thickness can be controlled in 6mm or so, fit
It is welded in using agitating friction, cost performance is high, and energy effective guarantee welding quality, ensures air-tightness.
Therefore, by above-mentioned assembling process, pile encapsulating housing 101 can be still able to satisfy in the lower situation of processing cost
Rapid processing, and preferable air-tightness can be provided.
Those skilled in the art can be obvious, the above exemplary embodiments of the invention can be carry out various modifications and modification and
Without departing from the spirit and scope of the present invention.Accordingly, it is intended to which present invention covering is made to fall in the appended claims and its equivalence techniques
Modifications of the present invention and modification in aspects.
