Background technology
High-tension battery in the prior art includes a large amount of single battery module, these battery modules are set to stable protection
Enclosure interior, the protection shell provide mechanical protection from all directions for battery module.Due to the energy of each single battery module
Metric density is all very high, and an independent battery module is on fire to be possible to cause serious harm.
Especially hybrid vehicle or electric vehicle, the traction battery that is installed on vehicle bottom, invade traction battery
Foreign matter there is a possibility that battery module is impaired, and then leads to its catching fire.
It is known that installation touching using respective design at the underbody position in front of traction battery (in terms of travel direction)
Hit guard member, such as the crash protection part of wedge shape.When bumping against corresponding barrier such as short column, crash protection part makes vehicle perpendicular
Histogram is to acceleration, so that the vehicle region equipped with traction battery under corresponding speed " jumping over " crosses barrier.
10 2,013 018 658 A1 of DE disclose a kind of underbody backplate of motor vehicles to reach same purpose, should
Underbody backplate at least partly coats downwards motor vehicles, wherein being equipped in some way at the underbody backplate at least one attached
Part, when motor vehicles, which ground one, is more than the protuberance or seamed edge of motor vehicles maximum ground clearance, this attachment is first grand with this
It rises or seamed edge is in contact.
Invention content
The present invention provides a kind of for the crash protection part of underbody battery and corresponding as described in following 1,3 and 7-9
Motor vehicles, method, computer program and the storage medium matched.
1. crash protection part (10) of the one kind for the underbody battery (12) of motor vehicles (20),
According to the travel direction (14) of the setting of the motor vehicles (20), which is installed on the underbody
In front of battery (12),
The crash protection part (10) is so shaped that, when the motor vehicles (20) in the travel direction (14) with this
When crash protection part (10) bumps against barrier (16), which accelerates perpendicular to the travel direction (14), and
The crash protection part (10) can be overhanging depending on the travel speed of the motor vehicles (20).
2. the crash protection part (10) as described in above-mentioned 1,
The crash protection part (10) is wedge shaped, and
The crash protection part (10) is carried out in a manner of it can be deflected around the axis extended transverse to the travel direction (14)
Installation.
3. a kind of motor vehicles (20),
The motor vehicles (20) include one for storage driving energy underbody battery (12) and
The motor vehicles (20) include that the crash protection part (10) as described in above-mentioned 1 or 2 is used for being the underbody battery (12)
Preventing collision protection is provided.
4. the motor vehicles (20) as described in above-mentioned 3,
The motor vehicles (20) further comprise that the control for keeping the crash protection part (10) overhanging drives dress
It sets, and
This can be electrically controlled depending on the travel speed to control the driving device.
5. the motor vehicles (20) as described in above-mentioned 4,
This is controlled the driving device including a servo motor.
6. the motor vehicles (20) as described in above-mentioned 4 or 5,
This is controlled the driving device including a fluid pressure drive device.
7. method of the one kind for providing preventing collision protection for the underbody battery (12) of motor vehicles (20),
Depending on the travel speed of the motor vehicles (20), make the crash protection part as described in any one of above-mentioned 1 to 6
(10) overhanging.
8. a kind of computer program is adapted for implementing all steps of the method as described in above-mentioned 7.
9. a kind of machine readable storage medium being stored with the computer program as described in above-mentioned 8.
The advantages of above-mentioned solution, is have the motor vehicles accordingly equipped by the active crash protection part
The ability of " jumping over " excessively any barrier completely is obtained under relatively low and fair speed, so that the barrier is at most only
The rear area of underbody battery can be invaded (in terms of travel direction).For this purpose, motor vehicles lift from suspension and only in obstacles
Level just resets when underbody battery rear.
Other Advantageous schemes of the present invention are contained in above-mentioned 2,4-6.The crash protection part can electrical controlled (example
Such as pass through servo motor) or the controlled mode of hydraulic pressure, special angle position is extended to according to the present speed of motor vehicles outside.It borrows
When this ensures that motor vehicles bump against barrier with any speed, " jumping over " barrier always all can be crossed completely.
Description of the drawings
The embodiment of the present invention is shown by attached drawing, will be hereafter described in detail.
The unique attached drawing of the present invention shows the motor vehicles side view according to embodiment of the present invention.
Specific implementation mode
Attached drawing shows the motor vehicle for being embodied as hybrid vehicle or electric vehicle according to embodiment of the present invention
20 basic structure.Motor vehicles 20 carry out storage driving energy using the traction battery for being embodied as high-tension battery.To reach this mesh
, which includes the lithium ionic cell module (not shown) of a large amount of single high-energy density, these battery modules are set to
Stable protection enclosure interior.The bottom of motor vehicles 20, hereinafter referred to as underbody battery 12 are installed in view of the battery.
Motor vehicles 20 further comprise substantially wedge shaped crash protection part 10, to provide anti-collision for underbody battery 12
Protection is hit, according to the set travel direction 14 of motor vehicles 20, which is installed on 12 front of underbody battery.It touches
The above-mentioned wedge shape of guard member 10 is hit it is ensured that when motor vehicles bump against barrier in travel direction 14 with crash protection part 10
When 16, motor vehicles 20 accelerate perpendicular to travel direction 14.Shown in reference to the accompanying drawings, short column and other objects on road form this
Class barrier 16.
In order to control this vertical direction acceleration, further there is motor vehicles 20 servo motor or hydraulic-driven to fill
That sets form controls the driving device (not shown).Under driving mode, this is controlled the driving device according to current driving speed
Crash protection part 10 is electrically controlled in this way so that crash protection part 10 is more and more overhanging when giving it the gun, and is subtracting
Speed increasingly inside contracts when driving.For this purpose, crash protection part 10 is with around the deflectable side of axis oriented transverse to travel direction 14
Formula is mounted on vehicle floor.
