Abstract
The invention discloses a device for connecting an electric water pump with a car body frame in an electric car. The device is composed of a device body. A connecting hole is formed in the device body, and the outer diameter of the electric water pump shares a concentric circle with the connecting hole. A slot where the car body frame is inserted is further formed in the device body. According to the device, the stable connection between the electric water pump and the car body frame is ensured, the influence of noise and vibration generated when the electric water pump works on the car body can be avoided, and safety and comfort of the electric car are ensured.
Description
Technical field
The present invention relates to electronlmobil parts are installed, particularly in electronlmobil, connect the device of electric water pump and vehicle body frame.
Background technology
Dynamic assembly and the orthodox car of electronlmobil have essential distinction, adopt drive motor to replace combustion engine.For water-cooled machine is cooling, need replace with electric water pump the mechanical water pump of combustion engine, this has just brought the noise of electric water pump large, has vibrated frequent problem.
The DC machine centrifugal pump that electronlmobil adopts at present, its principle of work is: the rotation of DC motor impeller, the refrigerant fluid of impeller part is subject to the centrifugal action that rotation produces, thrown to impeller peripheral outlet, and in generation meiobar, impeller center, refrigerant fluid is sucked from entrance, and then make refrigerant fluid produce and circulate in system.Consist of: DC machine, impeller, the pump housing, pump cover, pump shaft etc.
In electric water pump working process, there is mechanical noise, flow noise and electromagnetic noise, wherein mainly by the copsided operation of transmission of pressure in the pump housing, form the mechanical noise that impulsive force between parts or friction force cause and can pass through water pump support, through vehicle body, be delivered in operator's compartment, affect occupant's traveling comfort, so the transmission of the mechanical noise of isolation electric water pump has very important meaning to electric automobile whole NVH performance.
Summary of the invention
For there being technical matters in prior art, the invention provides a kind of device that connects electric water pump and vehicle body frame in electronlmobil, this device both can guarantee be connected firm with vehicle body frame of electric water pump, the noise sending in the time of can completely cutting off again electric water pump work and the vibration of generation impact vehicle body, guarantee electronlmobil safety, traveling comfort.
In order to solve the technical matters existing in prior art, the present invention adopts following technical scheme to implement:
A kind of device that connects electric water pump and vehicle body frame in electronlmobil, by device body, formed, on described device body, being provided with described electric water pump external diameter is concentrically ringed connecting bore, is also provided with and described vehicle body frame can be penetrated to slot wherein on described device body.
Described connecting bore internal diameter is less than described electric water pump external diameter 0.5～1mm.
Described slot vertical section is oblong.
Described device body is made by elastomeric material.
The beneficial effect of technical scheme provided by the invention is: the first, and the present invention firmly links together electric water pump, vehicle body frame by the first connecting bore, the second connecting bore, guarantees electronlmobil safety in the process of moving.Second, in the present invention, the first connecting bore, the second connecting bore adopt integral structure, and at the choice for use of material rubber raw materials, the noise having sent when so not only having reduced productive costs but also having isolated electric water pump work and the vibration of generation impact vehicle body, guarantee electronlmobil safety, traveling comfort.The 3rd, in the present invention, the first connecting bore internal diameter is less than described electric water pump external diameter 0.5～1mm, has strengthened the first connecting bore and has been connected fastening force with electric water pump.The 4th, the present invention designs ingenious, rational in infrastructure, easy to use, is adapted at electronlmobil field and promotes the use of on a large scale.

Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention uses structural representation in reality.
Reference numeral:
1-device body, 11-connecting bore, 12-slot, 3-electric water pump, 4-vehicle body frame
The specific embodiment
Below in conjunction with attached body, the present invention is described in further details:
As shown in Figure 1 and Figure 2, the invention provides a kind of device that connects electric water pump and vehicle body frame in electronlmobil, by device body 1, formed, on described device body 1, being provided with described electric water pump 3 external diameters is concentrically ringed connecting bore 11, is also provided with and described vehicle body frame 4 can be penetrated to slot 12 wherein on described device body 1.In order to guarantee that described connecting bore and described electric water pump suit better, described connecting bore internal diameter can be less than to described electric water pump external diameter in 0.5～1mm scope.Described slot vertical section is oblong.In actual production, the size of slot can be according to vehicle body frame 4 change in size.Described device body 1 is made by elastomeric material.Described device body 1 one-shot forming.
Production process of the present invention, first, adjusts connecting bore internal diameter size in advance, guarantees to be less than electric water pump outside dimension 0.5～1mm, and is sleeved on electric water pump.Subsequently, vehicle body frame penetrates from the bottom of slot and is fastening with it.
Above with reference to drawings and Examples, the present invention is schematically described, this description does not have restricted.Those of ordinary skill in the art will be understood that in actual applications, and in the present invention, the set-up mode of each parts some all may occur changes, and other staff also may make similar Design under its enlightenment.Only it is pointed out that otherwise depart from design aim of the present invention, all apparent changes and similar Design thereof, within being all included in protection scope of the present invention.
Claims (4)
