Embodiment
Core of the present utility model is to provide a kind of DC converter of electric motor car, makes the connection of itself and vehicle body simpler.Another core of the present utility model is to provide the electric motor car that comprises above-mentioned DC converter, simplifies complete vehicle structure, thus reduces costs.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of DC converter provided by the utility model.
In this embodiment, DC converting is the circuit realiration that consists of element various in electrical appliance module 3, therefore electrical appliance module 3 is the physical components generally adopted to realize DC converting.Its specific works process inputs high-tension electricity by input interface, exported after high-tension electricity being converted into low tension by output interface.Electrical appliance module 3 has positive and negative two output interfaces.The output cathode of electrical appliance module 3 is by the positive pole conducting of positive pole out connector 1 with car load low tension battery 6.The current-carrying part conducting of the output negative pole of electrical appliance module 3 and the shield shell 2 of DC converter, current-carrying part and mount pad 4 conducting of being fixed on outside shield shell 2, the metallic member of the direct conducting vehicle body of mount pad 4.Meanwhile, the negative pole of car load low tension battery 6 also with the metallic member conducting of vehicle body, thus define complete electric motor car low tension loop.
In this embodiment, the output negative pole of electrical module 3 connects the current-carrying part of shield shell 2, the current-carrying part connection seat 4 of shield shell 2, and mount pad 4 connects the metallic member of vehicle body, by the conducting between two of above-mentioned parts, define negative loop.The output negative pole that this mode is equivalent to DC converter directly with the metallic member conducting of vehicle body, and no longer by bonding wire harness connection bonding dots.Save the bonding wire harness needed through floor, and then also omit mistake line sheath and backplate accordingly, simplify complete vehicle structure, reduce cost.
In the DC converter that the utility model specific embodiment provides, the output negative pole of electrical appliance module 3 realizes conducting to the current-carrying part of shield shell 2 by corresponding conductor adapting piece 5.Conductor adapting piece 5 can be cable, due to the characteristic that cable can arbitrarily bend, uses cable to connect and according to the installation site of the inner miscellaneous part of shield shell 2, arbitrarily can bend cable, thus can not interfere.
In order to make shield shell 2 inside not interfere, as long as bent conductor adapting piece 5 all can realize the purpose of this utility model, copper bar has the low advantage of resistivity, and copper bar also has larger bending degree simultaneously, and conductor adapting piece 5 also can be copper bar thus.
According to actual conditions, conductor adapting piece 5 also can select miscellaneous part, as used electroconductive resin conductor.As long as can the output negative pole of conducting electrical appliance module 3 and the current-carrying part of shield shell 2, and do not interfere miscellaneous part, selected conductor adapting piece 5 is all within protection range of the present utility model.
When using the current-carrying part of the output negative pole of conductor adapting piece 5 conducting electrical appliance module 3 and shield shell 2, the two ends of conductor adapting piece 5 need to be connected with above-mentioned output negative pole and current-carrying part stably conducting.This requirement is realized by the mode of welding, above-mentioned output negative pole and current-carrying part are provided with pad, one end of conductor adapting piece 5 is welded in the pad of the output negative pole of electrical appliance module 3, and the other end of current-carrying part 5 is welded in the pad of the current-carrying part of shield shell 2.Thus realize stably conducting connection.
Also other connected modes can be selected, as directly compressed, as long as stably conducting corresponding part can be connected, all within protection range of the present utility model with pressing plate.
In above-mentioned embodiment, conductor adapting piece 5 is connected directly between in appropriate section, in order to make connection more stable, obtains another kind of embodiment of the present utility model further.Other structures of this execution mode are substantially identical with a upper embodiment, just install terminal additional at the two ends of conductor adapting piece 5, terminal is the conductor piece with through hole, and the output negative pole of electrical appliance module 3 and the current-carrying part relevant position of shield shell 2 are provided with screwed hole.Use bolt through the through hole on conductor piece, terminal is installed on the position at screwed hole place.This mode is stablized and is convenient to dismounting, is convenient for changing conductor adapting piece 5.
In this embodiment, terminal is the conductor piece with through hole, also can select other modes, if terminal is plug, arranges socket at the output negative pole of electrical appliance module 3 and the current-carrying part relevant position of shield shell 2.During installation, plug directly inserts in socket, and makes both closely fixing, also can play stable connection and easy-to-dismount effect.As long as can the output negative pole of conducting electrical appliance module 3 and the current-carrying part of shield shell 2, various mode be all within protection range of the present utility model.
In above-mentioned two embodiments, connected between the output negative pole of electrical appliance module 3 and the current-carrying part of shield shell 2 by conductor adapting piece 5, this connected mode there will be two tie points, and tie point can increase the rate of breakdown of device.Thus, another embodiment of the present utility model can be obtained further.
In this embodiment, the output negative pole of electrical appliance module 3 is made directly to contact with the current-carrying part of shield shell 2.Concrete mode is when manufacturing shield shell 2, makes current-carrying part have the structure that can be connected with the direct conducting of the output negative pole of electrical appliance module 3 in relevant position by the mode of mould integration.During installation, current-carrying part and output negative pole are directly connected and fix, and form negative loop.This mode decreases the tie point in loop, and then decreases the incidence of fault.
Except above-mentioned DC converter, embodiment of the present utility model also provides a kind of electric motor car comprising above-mentioned DC converter, and the structure of these other each several parts of electric motor car please refer to prior art, repeats no more herein.
Above electric motor car provided by the utility model and DC converter thereof are described in detail.Apply specific case herein to set forth principle of the present utility model and execution mode, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection range of the utility model claim.
