Abstract
The invention discloses electrical interface design for quick changing of a battery of an electric vehicle. The electrical interface design for the quick changing of the battery of the electric vehicle comprises a hanging frame assembly, a vehicle chassis electrical interface and a battery box electrical interface. The vehicle chassis electrical interface is arranged in the hanging frame assembly, and the battery box electrical interface is arranged below the vehicle chassis electrical interface. Through the utilization of the electrical interface design for the quick changing of the battery of the electric vehicle, the suction force of a magnet is used, and the electrical interfaces cannot be separated due to the fact that a vehicle bumps and a spring is slow in response. A waterproof rubber ring is stuck to the bottom of the vehicle chassis electrical interface, a circle of protruding rib is arranged on the battery box electrical interface, and after the rubber ring and the rib make tight contact with each other, sealing and water proof on the inner portion of the interfaces can be achieved. By means of the utilization of the hanging frame assembly of the vehicle chassis electrical interface, when a battery box waggles left and right slightly, the problem that the vehicle chassis electrical interface and the battery box electrical interface can rub with each other is solved.

In further embodiment of the present invention, for the structural entity of the electric interfaces design of fast changing battery of electric vehicle, be symmetrical structure.
In further embodiment of the present invention, the rotatable side of being located at upper cover plate 12 of turn buckle 13.
User can further be familiar with characteristic of the present invention and function according to following explanation:
The installation step of frame assembly 1, automobile chassis electric interfaces 2 and battery case electric interfaces 3 of suspending is as described below:
The assembling of frame assembly 1 suspends:
The first step: spin removable pin 7 is put to square yielding rubber circle 6, then through Z-shaped connection bracket 6, and then through suspending frame 4, the nut of screwing on down below, but nut not to be twisted too tightly, the frame 4 that keeps suspending can teetertotter.
Second step: the bolt on the mounting bracket 8 on automobile chassis is aimed in the hole in two Z-type connection brackets 5 that install on the frame 4 that suspends, then use nut screwing clamping.
The assembling of automobile chassis electric interfaces 2:
The first step: permanent magnetic iron block 23 is arranged in the stopper slot of lower cover 10 both sides.
Second step: first large current terminal A24, terminal springs A26, round insulation base 22, insulation cushion A20 and press strip support 19 are packaged in order, and then braiding copper strips one end is screwed on large current terminal A24, finally whole parts are contained in to lower cover 10 inside, and the outside hexagon socket head cap screw of screwing on; Same method, little electric current A25 four-core terminal, dielectric pin 28 are packaged, again the lead-out wire of four terminals is welded, again terminal springs B27, square insulating base 21 and press strip support 19 are packaged in order, and then whole parts are contained in to lower cover 10 inside, and the hexagon socket head cap screw of screwing on outside.
The 3rd step: high-low pressure socket is screwed on upper cover 9, then sealing ring 14 is placed on down and is covered, then the copper braid over braid other end is screwed on high-tension terminal, then low-voltage line is inserted in Low-voltage socket, finally upper and lower covers is tightened in together.
The 4th step: pack up turn buckle 13, automobile chassis electric interfaces 2 is inserted to the frame 4 that suspends interior to topmost, then stretch out turn buckle 13, so far, the electrical apparatus interface 2 of automobile chassis installs.
The assembling 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 large small terminal and insulation cushion are put through battery case electric interfaces panel 29, connect again each electric wire, line is inner through battery case electric interfaces 3 frames, finally with screw, battery case electric interfaces panel 29 is fixed on the step in battery case electric interfaces 3 frames.Finally just battery can be installed, and line, joint sealing.
In the process of whole fast changing battery, electric interfaces contact process is as follows:
When Battery case rises from lower to upper, first automobile chassis electric interfaces 2 inner elastomeric face contact terminals and the 3 terminal extruding of battery case electric interfaces, after spacing iron block 33 puts in place, interior as piston, integral body is up at the frame 4 that suspends for whole automobile chassis electric interfaces 2, thereby the spring that extruding automobile chassis electric interfaces 2 tops contact with the frame 4 that suspends, until battery case rises, finish, quick change electric interfaces has docked.In the time of dismounting, not needing has any action to quick change electric interfaces, directly down separated with battery case, because the deadweight of battery case is enough to make permanent magnetic iron block 23 separation.The thing should be noted, after dismounting battery case, not by magnetic conduction object as for suspending frame 4 times, in order to avoid held by permanent magnetic iron block 23.
In sum, structure of the present invention has specifically played following effect:
1, when battery case all around rocks slightly, in order to allow automobile chassis electric interfaces and battery case electric interfaces not rub, adopted a kind of automobile chassis electric interfaces frame that suspends that can be unsteady all around, the frame assembly upper end that suspends contacts with chassis spin, two spin alignment pin surroundings respectively contact with a square yielding rubber circle, when battery case rocks, automobile chassis electric interfaces together with the frame that suspends along with battery case rocks, so automobile chassis electric interfaces and battery case electric interfaces can not rub, avoid arcing, damage contact.
2, not separated for automobile chassis electric interfaces and battery case interface are better contacted, at the inner permanent magnet of installing of automobile chassis electric interfaces, utilize the suction of magnet, electric interfaces can not separated by spring low-response due to automobile bumpiness.
3, the spring of the face contact terminal of automobile chassis electric interfaces inside is larger, and automobile chassis electric interfaces top is smaller with the spring that the frame that suspends contacts, thereby in battery case uphill process, terminal contained spring first pushes, after the spring of top, push, the two poles of the earth spring guarantees that electric interfaces pressure is enough large, and deformation is large, is difficult for separately.
4, in the bottom of automobile chassis electric interfaces, be stained with one deck water proof rubber circle, and battery case electric interfaces there is the muscle of a circle projection, after both close contacts, can play the water-tight to electric interfaces inside; Under the lid of the mounting receptacle at automobile chassis electric interfaces top, also there is one deck water proof rubber circle, guarantee the waterproof of lid.
The foregoing is only preferred embodiment of the present invention; not thereby limit embodiments of the present invention and protection range; to those skilled in the art; should recognize that being equal to that all utilizations specification of the present invention and diagramatic content done replace and the resulting scheme of apparent variation, all should be included in protection scope of the present invention.
