Description
Technical field
The present invention relates to distribution box protection device technical field, in particular to a kind of fuse and with the fusing
The automobile of device.
Background technology
When electric automobile is because colliding, the high voltage parts of metal shell are very easy to deform after stress, the electricity of deformation
After device metal shell is contacted with internal high pressure copper bar, the dangerous situation such as short-circuit fire or personnel's electric shock can be caused, how can
Before the metal shell of deformation touches the exposed copper bar of internal high pressure, most of copper bar is allowed to be separated from from high voltage power supply, as height
Press the important directions of security fields research.
Conventional way one is that after an impact, crash sensor sends electricity of the collision alarm to responsible control high voltage connector
Unit is controlled, automatically controlled power supply, which is connected to after collision instruction, sends power-off signal to high tension distribution system, high by disconnecting contactor cut-out
Road is pushed back, the risk of this scheme there are two risks：(1) ECU judges preceding danger and had occurred and that；(2) colliding
Intelligent decision system is because signal line or power circuit are destroyed and can not complete whole logic judgment and power-off is dynamic in journey
Make.Other way is exactly to increase fuse in electric power loop, high tension loop fuse energy when expecting short-circuit after an impact
Enough to disconnect, the risk of this scheme is not exactly when being dead short, and collision causes to be connected to one etc. between high pressure both positive and negative polarity
On the generating resistor of effect, the local heating in the current range that fuse allows will cause vehicle fire to occur.
It can be seen that, the security of the mode in existing cutoff high loop is relatively low, it is impossible to meet people to electric automobile
The demand of security.
The content of the invention
It is a primary object of the present invention to provide a kind of fuse and automobile with the fuse, to solve prior art
In cut-out high-low circuit mode security it is relatively low the problem of.
To achieve these goals, according to an aspect of the invention, there is provided a kind of fuse, including：Housing, housing
Enclose and set to form installation cavity；Fuse link, fuse link is arranged in installation cavity；Cutting assembly, when cutting assembly is used to be acted on by external force
Fuse link is cut off.
Further, fuse link is vacantly arranged in installation cavity, is provided with first through hole on housing, and cutting assembly includes the
One push rod, the first push rod is arranged in first through hole, and extends to hull outside, and the first push rod or the first push rod from installation cavity
Extended line intersect with fuse link.
Further, it is provided with the second through hole on housing, cutting assembly also includes the second push rod, the second push rod is arranged on the
In two through holes, and hull outside is extended to from installation cavity, the extended line of the second push rod or the second push rod intersects with fuse link.
Further, the first push rod is located at the first side of fuse link, and the second push rod is located at the relative with the first side of fuse link
The second side.
Further, at least one the first push rod and the second push rod are positioned on fuse link by insulating bar.
Further, the first push rod and the second push rod are shifted to install.
Further, at least one the first push rod and the second push rod are perpendicular to fuse link.
Further, it is provided with filler in installation cavity.
Further, multiple through holes are provided with fuse link, multiple through holes are linearly arranged on fuse link, multiple through holes
Extending direction of the straight line of arrangement form perpendicular to fuse link.
According to another aspect of the present invention there is provided a kind of automobile, including fuse, fuse is above-mentioned fuse.
Apply the technical scheme of the present invention, during the fuse using the present invention, when fuse is made by external force
Used time, cutting assembly can cut off fuse link in the presence of external force, and then high-low pressure in loop of cutting off the electricity supply.By the present invention
Fuse use in distribution box, electric automobile or other structures when, when distribution box, electric automobile or other structures by
When being collided to external force effect, cutting assembly is acted on by external force, being capable of the cut-out fusing in time during generation is collided
Piece, it is to avoid intelligent decision system is because signal line or power circuit are destroyed and can not complete entirely to patrol in collision process
The appearance judged with the phenomenon of de-energizing actions is collected, in addition, fuse link is cut off in time can also avoid fire, is greatly improved
Distribution box, electric automobile or using the present invention fuse structure security.It can be seen that, fuse blows piece can be by
Shear action and disconnect it is this so that fuse mechanically can equally disconnect independent of current trigger scheme
High-tension electricity can be just fully disconnected initial stage by fuse in fuse housing distortion, so as to avoid short-circuit fire or personnel
Electric shock accidents occurs.
