Symmetrical structure.
In further embodiment of the present invention, the rotatable side set on upper cover plate 12 of turn buckle 13.
User can further recognize characteristic and function of the invention according to the following instructions:
The installation step for suspending frame assembly 1, automobile chassis electric interfaces 2 and battery case electric interfaces 3 is as described below:
Suspend the assembly of frame assembly 1:
Step 1: spin removable pin 7 is put on rectangular yielding rubber circle 6, it is then passed through Z-shaped connecting bracket 6, is then then passed through
Frame 4 is suspended, screws on nut down below, but nut is not twisted too tight, keeps suspension frame 4 that can teetertotter.
Step 2: the installation branch on the alignment of the hole in the two Z-type connecting brackets 5 installed on frame 4 automobile chassis will be suspended
Bolt on frame 8, then tightened with nut.
The assembly of automobile chassis electric interfaces 2:
Step 1: permanent magnetic iron block 23 is mounted in the limiting slot of 10 two sides of lower cover.
Step 2: first by high current terminal A24, terminal springs A26, round insulation pedestal 22, felt pad A20 and pressure
Bracket 19 packages in order, and then braiding copper strips one end is screwed on high current terminal A24 again, is finally mounted in whole part
Inside lower cover 10, and hexagon socket head cap screw is screwed in outside；Same method packages tetra- core terminal of low current A25, dielectric pin 28,
The lead-out wire of four terminals is welded again, then by terminal springs B27, square insulating pedestal 21 and press strip bracket 19 by suitable
Sequence packages, and then again by whole part inside lower cover 10, and screws on hexagon socket head cap screw outside.
Step 3: high-low pressure socket is screwed in upper cover 9, then sealing ring 14 is placed on lower lid, then copper braid over braid is another
One end is screwed on high-tension terminal, and then low-voltage line is inserted into Low-voltage socket, is finally screwed together upper and lower covers.
Step 4: packing up turn buckle 13, automobile chassis electric interfaces 2 are inserted into suspension frame 4 to the top, then stretch out rotation
Turn button 13, so far, the electrical apparatus interface 2 of automobile chassis installs.
The assembly of battery case electric interfaces 3:
Before battery is installed, first battery case electric interfaces panel 29 is carefully connected the wire and installed, specifically first by big small end
Son and felt pad are put on across battery case electric interfaces panel 29, reconnect each electric wire, and line passes through 3 frame of battery case electric interfaces
Battery case electric interfaces panel 29 is finally fixed on the step in 3 frame of battery case electric interfaces with screw by inside.Finally
Battery, and line, joint sealing can be installed.
Electric interfaces contact process is as follows during entire fast changing battery:
When Battery case rises from lower to upper, first 2 inner elastomeric face contact terminal of automobile chassis electric interfaces and electricity
Case electric interfaces 3 terminal in pond squeezes, and after limiting iron block 33 in place, entire automobile chassis electric interfaces 2 are in suspension frame 4 as living
Plug equally it is whole up, thus squeeze 2 top of automobile chassis electric interfaces with the spring that suspends frame 4 and be in contact, until battery case
Rising terminates, and the docking of quick change electric interfaces is completed.When disassembly, do not need have any movement to quick change electric interfaces, directly
It is separated down with battery case, because the self weight of battery case is enough to separate permanent magnetic iron block 23.The thing that should be noted is being dismantled
It, should not be by magnetic conduction object as under suspension frame 4, in order to avoid be sucked by permanent magnetic iron block 23 after battery case.
In conclusion structure of the invention specifically serves to ensure that
1, when battery case all around shakes slightly, in order to allow automobile chassis electric interfaces electrically to connect with battery case
Mouth does not rub, and suspends frame using the automobile chassis electric interfaces that one kind can all around float, suspends on frame assembly
End is contacted with chassis spin, and two spin positioning pin surroundings are respectively contacted with a rectangular yielding rubber circle, is shaken in battery case
When, automobile chassis electric interfaces and suspension frame are together as battery case shakes, so automobile chassis electric interfaces and battery case
Electric interfaces will not rub, and avoid arcing, damage contact.
2, not separated in order to contact automobile chassis electric interfaces preferably with battery case interface, it is electrically connect in automobile chassis
It is mouthful internal that permanent magnet is installed, using the suction of magnet so that electric interfaces will not due to automobile bumpiness and spring low-response and divide
It opens.
3, the spring of the face contact terminal inside automobile chassis electric interfaces is bigger, and automobile chassis electric interfaces
The spring that top is in contact with suspension frame is smaller, so that terminal inner spring first squeezes in battery case uphill process,
It is squeezed after the spring of top, the two poles of the earth spring guarantees that electric interfaces pressure is sufficiently large, and deformation is big, is not easy to separate.
4, it is stained with one layer of waterproof rubber ring in the bottom of automobile chassis electric interfaces, and battery case electric interfaces have a circle prominent
The muscle risen can play after the two is in close contact to the sealing waterproof inside electric interfaces；At the top of automobile chassis electric interfaces
Installation socket lid under also have one layer of waterproof rubber ring, guarantee the waterproof of lid.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
Equivalent replacement and obviously change obtained scheme, should all be included within the scope of the present invention.
