Abstract
The utility model relates to an electrified quick -witted detection device's electric automobile vacuum pump, including the vacuum pump main part, its characterized in that: still include controller, speed sensor and be used for detecting the power source detection circuit of mains voltage and electric current, speed sensor fixed mounting is in the vacuum pump main part, and power source detection circuit's input is connected with the vehicle mounted power's voltage output end, speed sensor, the respective output of power source detection circuit and controller are connected.
Description
Technical field
What this utility model was related to is the vacuum pump of electric automobile of powered machine detecting device.
Background technology
Existing vacuum pump of electric automobile, if there is fault, has three kinds of reasons：Motor damage, power issue, air flue are not
Sealing.Traditional detection method（It is repeatedly detected pressure value in vacuum tank after starting vacuum pump）Can only detect whether vacuum pump damages
Badly it is impossible to quickly judge cause of damage.And traditional detection method detection method needs one judge the time（It is usually 5 seconds）
The working condition of Real-time Feedback vacuum pump cannot be accomplished.It is thus desirable to design is a can quickly judge whether vacuum pump damages simultaneously
And may determine that the vacuum pump detection means of cause of damage, in order to detect the reason vacuum pump of electric automobile breaks down.
Utility model content
In view of this, in order to solve the above problems, the vacuum pump of electric automobile of the powered machine detecting device of the new offer of basis.
The vacuum pump of electric automobile of powered machine detecting device, including vacuum pump main body it is characterised in that also including controlling
Device, speed probe and the power sense circuit for detecting supply voltage and electric current, described speed probe is fixedly mounted on
In vacuum pump main body, the input of power sense circuit is connected with the voltage output end of vehicle power；Described speed probe, electricity
The respective outfan of power sense circuit and controller connect.
Further, described speed probe and power sense circuit integrated after or not integrated power supply testing circuit, peace
It is contained in the shell inside bottom of vaccum pump motor main shaft, now the outer cover length of vaccum pump motor main shaft exceedes vaccum pump motor master
The length of axle is to accommodate integrated later speed probe and power sense circuit.
Further, described speed probe and power sense circuit integrated after or not integrated power supply testing circuit, peace
It is contained in outside motor, and is wrapped up by vaccum pump motor main shaft shell, now the housing diameter of vaccum pump motor main shaft is more than electricity
Machine diameter is to accommodate speed probe.
Further, described speed probe adopts Hall element, now pacifies on vacuum pump vaccum pump motor main shaft
Dress and the corresponding Magnet of Hall element.
Further, described speed probe adopts photoelectric sensor, now pacifies on vacuum pump vaccum pump motor main shaft
Dress and the corresponding reflector of photoelectric sensor.
When motor stops the rotation, controller can be according to the signal of input, and judgement is power failure（By power detecting
Circuit）, or electrical fault（By Hall element）, and feed back on automobile instrument.
Brief description
Fig. 1 is motor detection apparatus circuit diagram.
Fig. 2 is embodiment 1 schematic view of the mounting position.
Fig. 3 is embodiment 2 schematic view of the mounting position.
Specific embodiment
Embodiment 1：
As Fig. 1,2, the vacuum pump of electric automobile of powered machine detecting device, including vacuum pump main body, also include controller 2,
Speed probe 1 and the power sense circuit 3 for detecting supply voltage and electric current, described speed probe 1 is fixedly mounted on
In vacuum pump main body, the input of power sense circuit 3 is connected with the voltage output end of vehicle power；Described speed probe 1,
The respective outfan of power sense circuit 3 and controller 2 connect.Described speed probe 1 and power sense circuit 3 integrated with
Afterwards, it is arranged on shell 4 inside bottom of vaccum pump motor main shaft 5, now shell 4 length of vaccum pump motor main shaft 5 exceedes very
The length of empty pump motor main shaft 5 is to accommodate integrated later speed probe 1 and power sense circuit 3.
Embodiment 2：
As Fig. 3, compare with embodiment 1, the difference of embodiment 2 is that described speed probe 1 is arranged on outside motor 6,
And wrapped up by the shell 4 of vaccum pump motor main shaft 5, now the shell 4 of vaccum pump motor main shaft 5 is with diameter greater than motor 6 diameter
To accommodate speed probe 1 and power sense circuit 3.
