Description
Technical field
It the utility model is related to vehicle technology field, and in particular to a kind of two level anti-drop device for battery case.
Background technology
Electric car, i.e. electric drive vehicle, also known as electricity are driven.Electric car is divided into alternating current electric vehicle and DC electric car.Usually
The electric car said is using battery as energy source, by components such as controller, motors, converts electrical energy into mechanical energy movement,
To control size of current to change the vehicle of speed.Electric vehicle portion in national economy is not very high, but it meets
The fixed energy conservation and environmental protection trend of country, greatly facilitates short distance traffic, main is by the saving and protection to the energy and environment
Play an important role in national economy.
Most crucial component is battery case in electric car, and battery case is exactly the babinet for being used to contain battery as its name suggests,
For the ease of being overhauled and being safeguarded to battery, chamber door is equipped with battery case, chamber door is prevented opening by door lock to realize entirely, therefore case
The reliability of door is heavily dependent on the quality of door lock, and in order to which beauty, door lock also progressively use and hide interior lock tongue
Structure.Hiding interior lock bolt structure includes a rotatable lock tongue, by making lock tongue and box house overlap box door lock
On, but electric car, during movement, the impact of long-term vehicle can cause the failure of lock body, cause lock tongue and box house
Do not overlap, chamber door is not pinned and automatically opened up, and causes security incident.
Utility model content
The utility model is intended to provide a kind of two level anti-drop device for battery case, with solve in the prior art lock tongue and
When box house does not overlap, the problem of chamber door automatically opens up.
A kind of two level anti-drop device for battery case in this programme, including permanent magnet outside babinet and set
In the electromagnet of box house, the permanent magnet and electromagnet are correspondingly arranged, and one end of the permanent magnet extends to chamber door
On, multiple first springs, one end of the first spring and the outer wall of babinet are connected between the outer wall of the permanent magnet and chamber door
Connection, the other end of the first spring are connected with permanent magnet, and the electromagnet is electrically connected with slide rheostat, the slip variable resistance
Device includes the base for being fixed on box house, and the base is equipped with resistance wire, and the resistance wire, which is equipped with, to be used to adjust resistance value
Sliding block, be equipped with second spring between the side wall of the sliding block and base, the ultimate range between the sliding block and lock tongue is equal to
The length of lock tongue.
The operation principle of the utility model：When carrying out two level anticreep using the anti-drop device in this programme, make slip variable resistance
Device is powered, and the both ends of slide rheostat apply certain voltage.The level-one anticreep that lock tongue completes battery case chamber door is rotated at this time, by
Ultimate range between resistance wire and lock tongue is equal to the length of lock tongue, and lock tongue is during rotating, between lock tongue and sliding block
Distance be gradually reduced, while sliding block has certain thickness, and lock tongue promotes sliding block on resistance wire in rotary course at this time
It is mobile, and second spring is in the inside overlap joint completion level-one anticreep of extended state, lock tongue and babinet, it is linked into circuit
Resistance wire resistance value gradually increases, and the voltage applied on electromagnet is certain, small by the electric current of electromagnet, the magnetic intensity of electromagnet
It is small；Electromagnet and permanent magnet are correspondingly arranged inside and the outer wall of babinet, and permanent magnet is connected with the first bullet being used to support
There is certain gap, the generation magnetic force of electromagnet attracts permanent magnet to have court between the outer wall of spring, permanent magnet and babinet
The trend moved to cabinet exterior, but at this time because electric current is small, this attraction is also small, is not enough to overcome the bullet of the first spring
Power, permanent magnet remain stationary as.
When the failure of lock body, due to the out-of-flatness in the traveling process of electric car because road surface, the state in top slope,
This vibration force is larger, and the amount of lap between lock tongue and cabinet wall is gradually reduced at this time, and lock tongue rotation, lock tongue is not supporting
Sliding block, second spring are replied, and sliding block is moved on resistance wire, and the resistance wire resistance value being linked into circuit gradually increases small, passes through
The electric current of electromagnet is gradually big, and the magnetic intensity of electromagnet gradually increases, and the adsorption capacity of electromagnet absorption permanent magnet gradually increases,
When the inner wall of lock tongue and babinet does not overlap, electromagnet adsorption capacity reaches maximum, this adsorption capacity overcomes the bullet of the first spring
Power, making permanent magnet adsorbing, one end of permanent magnet is extended on chamber door on the outer wall of babinet, and permanent magnet is to be used for and case
Door tower connects, and the gap between permanent magnet and babinet disappears at this time, and permanent magnet and chamber door overlap joint, chamber door is because the resistance of electromagnet
Gear, so will not just realize two level anticreep towards external opening.
The beneficial effects of the utility model：The resistance value of slide rheostat is adjusted in this programme by the rotation of lock tongue, when
When lock tongue and tower of locking a door connect, the resistance wire resistance value being linked into circuit is big, and the adsorption capacity of electromagnet is insufficient to allow permanent magnet gram
Take the elastic force of the first spring, when lock tongue and lock a door do not have tower to connect when, the resistance wire resistance value being linked into circuit is small, the absorption of electromagnet
Power makes permanent magnet overcome the elastic force of the first spring, and permanent magnet and chamber door tower connect, so just realize two level anticreep, avoid case
Door is automatically opened up without pinning, and causes security incident.
Further, the outer wall of first spring and babinet is detachably connected.When battery is put into battery case, forever
Magnet can stop the opening of chamber door, therefore be detachably connected the outer wall of the first spring and babinet, easy to which permanent magnet is dismantled,
Chamber door is set to open.
Further, the sliding block is equipped with anti-skid chequer.When lock tongue promotes sliding block movement, anti-skid chequer is beneficial to promote.
Further, the permanent magnet outer surface includes being wrapped with metallic sheath.Due in the traveling process of electric car because road
The out-of-flatness in face, the state in top slope, vibration force is larger, and permanent magnet can be shattered, and causes to fail, therefore designs metallic sheath
To avoid occurring.
Further, the metallic sheath is equipped with opening close to the side of cabinet exterior, and the side of permanent magnet and opening are in
Same vertical plane.The side of permanent magnet and opening are in same vertical plane, when permanent magnet and chamber door tower connect, permanent magnet
Directly adsorb on chamber door, fixation is more firm.
