According to the accompanying drawings will be more to the detailed description of the utility model specific embodiment, those skilled in the art Add clear of the present utility model above-mentioned and other purposes, advantages and features.
Brief description of the drawings
It is described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter more of the present utility model specific real Apply example.Identical reference denotes same or similar part or part in accompanying drawing.It should be appreciated by those skilled in the art that What these accompanying drawings were not necessarily drawn to scale.In accompanying drawing:
Fig. 1 is the schematic diagram according to the electrokinetic cell bag collision protection system of the utility model one embodiment;
Fig. 2 is the indicative flowchart according to the electrokinetic cell bag collision protection system of the utility model one embodiment;
Fig. 3 is the schematic structure according to the electrokinetic cell bag collision protection system of the utility model another embodiment Figure.
Embodiment
Fig. 1 is the schematic diagram according to the electrokinetic cell bag collision protection system of the utility model one embodiment. Electrokinetic cell bag collision protection system may include sensor assembly 1, high-voltage relay 3 and battery management system 2 in general manner.Pass Sensor module 1 is used to monitor the motion state of vehicle and sends collision alarm, has normal condition and SM set mode, wherein, pass The normal condition of sensor module 1 refers to measured information and not up to condition, it is impossible to makes sensor according to certain rules measurement Information be for conversion into electric signal or other required forms information output state.High-voltage relay 3 have closure state and Off-state.When high-voltage relay 3 closes, electrokinetic cell bag is powered to vehicle, there is provided power;When high-voltage relay 3 disconnects, move Power battery bag stops powering to vehicle.Battery management system 2 is connected with high-voltage relay 3 and sensor assembly 1, according to sensing The state of device module 1 controls the high-voltage relay 3 to realize closure state or the off-state.
The sensor assembly 1 can include gravity sensing sensor 11,3-axis acceleration sensor 12, driving radar 13 With three-axis gyroscope 14.Aforementioned four device is respectively provided with normal condition and SM set mode.
The SM set mode of sensor assembly 1 is in and put for any three in aforementioned four device and its apparatus above simultaneously Position state.When sensor assembly 1 is in SM set mode, battery management system 2 then judges to collide and disconnect high-voltage relay Device 3.
Gravity sensing sensor 11 has is made cantilevered shifter using elastic sensing element, with using the sensitive member of elasticity Energy-stored spring made of part drives electric contact, completes the conversion from Gravity changer to electric signal.Gravity sensing sensor 11 Using vehicle body manipulation, security system and navigation is concentrated mainly on, typical application such as safe automobile air bag (Airbag), ABS prevents Locking brake system, ESP (ESP), electronically-controlled suspension system etc..When Gravity changer exceeds preset value, the gravity Inductive pick-up 11 can be considered at SM set mode.
3-axis acceleration sensor 12 is that the general principle based on acceleration goes to realize work, have in terms of monitoring is collided compared with More applications.3-axis acceleration sensor 12 is in the case where not knowing the occasion of movement direction of object in advance, is only added using three axles Velocity sensor detects acceleration signal.3-axis acceleration sensor has small volume and feature in light weight, can measure sky Between acceleration, the kinetic property of object can be accurately reflected comprehensively.When the change of steric acceleration is more than preset value, described three Axle acceleration sensor 12 is considered at SM set mode.
Driving radar 13 is the safety aid of vehicle, by ultrasonic sensor (being commonly called as popping one's head in), controller and display The part such as device (or buzzer) forms.Can with sound or more intuitively the situation of driver's peripheral obstacle is informed in display, Relieve and caused puzzlement is all around visited when driver parks, moves backward and started vehicle, and help driver to clear away The defects of blind area and blurred vision, improve the security of driving.When the feedback signal for radar 13 of driving a vehicle is more than preset value, It is considered at SM set mode.
The maximum effect of three-axis gyroscope 14 is exactly to measure angular speed, to differentiate the motion state of object.When angular speed When change exceedes preset value, the three-axis gyroscope 14 is considered at SM set mode.
When three in aforementioned four sensor and its above are in SM set mode, battery management system 2 judges vehicle In collision status, high-voltage relay 3 is disconnected, electrokinetic cell bag is stopped power supply, and reduces potential safety hazard.
Using a kind of electrokinetic cell bag collision protection system of the present utility model, because the processor that its circuit passes through is few, Therefore simple in construction, the reaction time is exceedingly fast, and reliability is high, can individually judge the effective safety for improving new energy car Property.
Fig. 3 is the schematic structure according to the electrokinetic cell bag collision protection system of the utility model another embodiment Figure.As shown in figure 3, electrokinetic cell bag collision protection system also includes alarm unit 5.The alarm unit 5 passes through sound or figure As being alarmed.The alarm unit 5 can be LED indicating members.LED indicating members are connected with battery management system, battery Management system controls the LED indicating members to send out while controlling the high-voltage relay 3 to realize closure state or off-state Light.For example, when high-voltage relay 3 is in closure state, LED indicating members display green;Disconnected when high-voltage relay 3 is in During state, the display of LED indicating members is red.
In another embodiment of the present invention, the electrokinetic cell bag collision protection system also includes entire car controller 4, Vehicle is judged according to the signal that the battery management system 2 feeds back.
Fig. 2 is the indicative flowchart according to the electrokinetic cell bag collision protection system of the utility model one embodiment. As shown in Fig. 2 after vehicle launch, high-voltage relay 3 is closed, and electrokinetic cell bag is powered to vehicle, there is provided power, battery management system System 2 brings into operation, and monitors gravity sensing sensor 11,3-axis acceleration sensor 12, driving radar 13 and three axis accelerometer in real time The state of instrument 14, when three in aforementioned four sensor and its sensor of the above are in SM set mode, battery management system System 2 then judges that vehicle collides, and disconnects high-voltage relay 3, and send alarm to entire car controller 4.Entire car controller 4 is connecing After receiving signal, vehicle is judged.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model more Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the spirit and scope of the utility model The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new The scope of type is understood that and regarded as to cover other all these variations or modifications.
