The invention further provides a motor vehicle, a method, a computer program and a storage medium which are correspondingly matched to the impact protection part.
Description
Technical field
The present invention relates to a kind of crash protection part for battery at the bottom of car (Unterbodenbatterie).The invention still further relates to corresponding coupling motor vehicles, method, computer program and storage medium.
Background technology
High-tension battery of the prior art comprises a large amount of single battery modules, and these battery modules are establishedIn stable protection enclosure interior, this protection housing from all directions for battery module provide machineryProtection. Because the energy density of each single battery module is all very high, an independent battery moduleOn firely just likely cause serious harm.
Especially traction battery motor vehicle driven by mixed power or electric vehicle, that be installed on vehicle bottom,The foreign matter of invading traction battery likely makes battery module impaired, and then causes its catching fire.
Be known that position installation is adopted at the bottom of the car of traction battery front (from travel direction)With the crash protection part of respective design, the crash protection part of for example wedge shape. Bumping against corresponding barrierWhile hindering thing as short column, crash protection part makes vehicle accelerate at vertical direction, leads thereby make to be provided withDraw the vehicle region under the corresponding speed of a motor vehicle " jumping over " of battery and cross barrier.
DE102013018658A1 is the car that reaches same object and disclose a kind of motor vehiclesEnd backplate, at the bottom of this car backplate down to small part coating machine motor vehicle, wherein backplate at the bottom of this carPlace is provided with at least one annex in some way, exceedes motor vehicles when motor vehicles grind oneWhen the protuberance of maximum ground clearance or seamed edge, this annex first comes in contact with this protuberance or seamed edge.
Summary of the invention
The invention provides as following 1,3 and 7-9 as described in a kind of crash protection for battery at the bottom of carPart, and the motor vehicles of corresponding coupling, method, computer program and storage medium.
1. the crash protection part (10) for battery (12) at the bottom of the car of motor vehicles (20),
-according to the travel direction (14) of the setting of these motor vehicles (20), this crash protection part(10) be installed on battery (12) front at the bottom of this car,
-this crash protection part (10) is so shaped that, when these motor vehicles (20) are at this rowSail when direction (14) is upper bumps against barrier (16) with this crash protection part (10), this is motor-drivenVehicle (20) accelerates perpendicular to this travel direction (14), and
-this crash protection part (10) can depend on these motor vehicles (20) travel speed andOverhanging.
2. the crash protection part (10) as described in above-mentioned 1,
-this crash protection part (10) is wedge shape, and
-this crash protection part (10) is with the axis energy around extending transverse to this travel direction (14)The mode of enough deflection is installed.
3. motor vehicles (20),
-these motor vehicles (20) comprise that one for battery (12) at the bottom of the car of storing driver energyAnd
-these motor vehicles (20) comprise crash protection part (10) use as described in above-mentioned 1 or 2For battery (12) at the bottom of this car provides preventing collision protection.
4. the motor vehicles (20) as described in above-mentioned 3,
-these motor vehicles (20) further comprise that one for making this crash protection part (10)Overhanging accessory drive, and
-depend on that this travel speed can electrically control this accessory drive.
5. the motor vehicles (20) as described in above-mentioned 4,
This accessory drive comprises a servo motor.
6. the motor vehicles (20) as described in above-mentioned 4 or 5,
This accessory drive comprises a fluid pressure drive device.
7. battery (12) provides preventing collision protection at the bottom of a car that is used to motor vehicles (20)Method,
Depend on the travel speed of these motor vehicles (20), make as any one in above-mentioned 1 to 6Described crash protection part (10) is overhanging.
8. a computer program, is adapted for all of the method as described in above-mentioned 7 of implementingStep.
9. one kind stores the machinable medium of the computer program as described in above-mentioned 8.
The advantage of above-mentioned solution is, the motor vehicles with corresponding equipment are active by thisCrash protection part and obtained under lower and fair speed " jumping over " completely and cross any barrierAbility, thereby make this barrier can only invade at most the rear area of battery at the bottom of car (fromTravel direction is seen). For this reason, motor vehicles lift and are only positioned at car at barrier from suspension, just reset when at the battery rear, the end.
That other useful technical schemes of the present invention are contained in is above-mentioned 2, in 4-6. This crash protection part canFor example, with electric controlled (passing through servo motor) or the controlled mode of hydraulic pressure, according to motor vehiclesPresent speed and extend special angle position outward. Guarantee that whereby motor vehicles hit with any speedDuring to barrier, all always can " jump over " completely and cross this barrier.
Brief description of the drawings
The embodiment of the present invention is illustrated by accompanying drawing, below will be described in detail.
Shown in the unique accompanying drawing of the present invention is the motor vehicles side-looking according to embodiment of the present inventionFigure.
Detailed description of the invention
Shown in accompanying drawing is to be embodied as motor vehicle driven by mixed power or electronic according to embodiment of the present inventionThe basic structure of the motor vehicles 20 of vehicle. Motor vehicles 20 uses are embodied as high-tension batteryTraction battery is carried out storing driver energy. For reaching this object, this power brick is containing a large amount of single high energyThe lithium ionic cell module (not shown) of metric density, these battery modules are located at stable guarantorProtect enclosure interior. In view of this battery is installed on the bottom of motor vehicles 20, below will be referred to as carEnd battery 12.
Motor vehicles 20 further comprise the crash protection part 10 that is substantially wedge shape, so that at the bottom of being carBattery 12 provides preventing collision protection, according to the travel direction setting 14 of motor vehicles 20,This crash protection part is installed on battery 12 fronts at the bottom of car. The above-mentioned wedge shape of crash protection part 10 canTo guarantee, when motor vehicles bump against barrier 16 with crash protection part 10 in travel direction 14Time, motor vehicles 20 accelerate perpendicular to travel direction 14. With reference to the accompanying drawings, on roadShort column and other objects form this type of barrier 16.
In order to control this vertical direction acceleration, motor vehicles 20 further have servo horseReach or the accessory drive (not shown) of fluid pressure drive device form. Under driving mode,This accessory drive is controlled crash protection according to current line vehicle speed like this in electric modePart 10, makes crash protection part 10 more and more overhanging in the time giving it the gun, and in the time of Reduced Speed Now, gets overMore inside contract. For this reason, crash protection part 10 is with the axis around transverse to travel direction 14 orientationsDeflectable mode is arranged on vehicle floor.
