Detailed description of the invention
The engine compartment cover described with sub-fraction front in Fig. 1 is to 3 or hood
Represent with 10.Visible engine compartment cover, such as go towards forward relative to fork truck, be in fork
Front wall segments in the driver's cabin of car, this front wall segments is such as covered by engine compartment cover to arrive
Electromotor and towards upper deflecting.The front wall segments of engine compartment cover has the space 12 of slit-shaped, but should
Space is closed by deflectable the stop element 14 being arranged on inner side so that deflecting element 14
And the inner rim limiting the engine compartment cover edge in space 12 limits the opening of all round closure.Press
Fig. 1, handles key 16 and stretches out through this opening, and this manipulation key is inserted into battery separators 18
Key socket in.By key 16 being inserted in the keyhole of battery separators 18, electricity
Pond separator is switched to the first state, and in the first state, Vehicular battery or starter battery lead to
Cross battery separators and vehicle electrical network and therefore electrically connect with vehicle internal combustion engine.By extracting manipulation
Key 16, therefore battery with vehicle electrical network and disconnects, because battery separators proceeds to internal combustion engine
In the second state.
Stop element 14 is arranged on the inner side of engine compartment cover and example in terms of its mobility
As limited by the bending section of vehicle hatchcover so that stop element can only be along court from the position of Fig. 1
On direction deflection, as shown in Figure 3.If attempting opening when engine compartment cover is closed starting
Cabin cover, then stop element 14 lean against on the manipulation key 16 of insertion with its top edge gear and
Engine compartment cover is stoped to continue to open.
Therefore hood 10 just can only be opened after extracting manipulation key 16.This is at figure
Described in 2.Keyhole represents with 20, by Fig. 1, handles key 16 and is inserted in keyhole.
If extracting manipulation key 16, then hood 10 can arbitrarily open and close.
When hood is opened, handle key 16 can insert again, in order to by battery again with car
Electrical network connects, such as in order to start internal combustion engine in the range of maintenance work.
When key inserts and therefore as it is shown on figure 3, may can also when internal combustion engine operation
Close engine compartment cover 10.Engine compartment cover 10 is still being closed despite the manipulation key inserted
Time, stop element 14 gear leans against on the key and deflects on deviation post so that enging cabin
Lid can occupy the position corresponding with Fig. 1 the most without problems.Advantageously, stop element 14 is permissible
Biased towards the entopic direction described in fig 1 and 2 by spring assembly so that backstop
Element automatically and the most again occupies close corresponding with Fig. 1 and 2 after closing hood
Lock position.
In above-mentioned form of implementation, starting point is, battery separating switch 18 handles key by inserting
Spoon 16 and be switched to conduction the first state and by extract handle key and be switched to power-off
The second state.This is a kind of suitable structure.But can the most alternatively set in contrast
Fixed, battery separating switch 18 enters conduction state by inserting manipulation key 16 the most,
But also need to rotate to one by handling key from the position of Fig. 1 after inserting manipulation key
Position, such as, have rotated the position of 90 °.On this position that have rotated, battery separating switch
It it is conduction.But handle extracting of key 16 only back rotating to manipulation key by Fig. 1
Position after be only possible.The closedown of hood is preferably handling the two rotation of key
It is all possible that indexing is put.Other instruction can also be set without problems for handling key
The position of rotation of other function.
Show the substantially corresponding with the safety device of Fig. 1 to 3 of certain difference in the diagram
The internal view of safety device.Battery separating switch 18 is kept by fixed holding plate 30.
The locked position of coupler of the level of stop element 14 is limited by the curved edge of engine compartment cover 10.
Fulcrum post 36 on the inner side of hatchcover 10 is for the deflection supporting of stop element, around this
Consign and back-moving spring may be set.
Fig. 5 shows the structure of a kind of replacement with the internal view being similar to Fig. 4.Here, manipulation key
Spoon or the operating element 16 ' that match fixing with battery separating switch 18 ' are disposed entirely within interior room
And the most pent engine compartment cover 10 ' covers.Operating element 16 ' has the backstop of bending
Section 17 ' and being adjusted between position and invalid position activating by rotation, is activating position
On, battery is connected by battery separating switch 18 ' with vehicle electrical network, and on invalid position, battery divides
Leave pass 18 ' disconnecting circuit.Fig. 5 shows that operating element 16 ' is on activation position.If it is existing
Opening engine compartment cover 10 ', i.e. towards upper deflecting, then stop element 14 ' is at engine compartment cover 10 '
Inner side on gear to lean against the backstop section 17 ' of operating element 16 ' upper and make operating element rotate to
On invalid position.Therefore opening engine compartment cover 10 ' when electromotor runs necessarily causes circuit to break
Open and therefore electromotor cuts off.
If desired, such as maintenance work, can will grasp when hatchcover 10 ' is opened
Vertical element 16 ' rotates back on activation position, such as in order to start electromotor.If closed the most again
Engine compartment cover 10 ', then operating element 16 ' is maintained on this activation position, because stop element
14 ' can offset in the case of gear leans against on backstop section 17 ' when closing hatchcover 10 '.Bias bullet
Stop element 14 ' can be biased by spring to by the normal position of Fig. 5.
According at Fig. 6 to 12 in represent embodiment, hood (covering) with match
Only produce indirectly between the operating element of battery separating switch, the most roundabout mechanical type
Effect connect (Wirkverbindung), to realize security function, as explained below.
In order to explain this another embodiment, similar or correspondence parts are used and Fig. 1 to 4
In identical reference, but increase 100 respectively.
By Fig. 6 to 8, the space 112 through engine compartment cover or hood 110 is inserted into
Manipulation key 116 in the key socket of battery separators 118 is in it and activates on position, makes
Obtain battery separators and be in its first state, in this first state, Vehicular battery or starter
Therefore battery by battery separators and vehicle electrical network and electrically connects with vehicle internal combustion engine.Electromotor
Hatchcover is to close and prevent from opening by means of blocking mechanism 150.In order to open enging cabin
Lid or hood 110, it is necessary to handling and open element 152, this unlatching element is directly being in sky
Region after gap 112 has operator region 154.But handle the operating space of key 116
Section 156 is configured to shadowing elements, and this shadowing elements covers unlatching element on activation position outwardly
The operator region 154 of 152 so that this operator region can not be from external control.Therefore, electromotor
Hatchcover or hood are on the activation position handling key 116 and therefore at battery separators
First state of 118 prevents from opening.
In order to open engine compartment cover or hood 110, need to make manipulation key 116 enter
It is on the invalid position shown in Fig. 9, and if be specified that, then separate from battery
Extract on device.As shown in Figure 9, the operator region 154 opening element 152 is handling key 116
Invalid position on can be reached from outside by space 112 so that in order to open engine compartment cover
Hood 110 can handle unlatching element 152 in other words, and on this invalid position, battery divides
And therefore separate battery and vehicle electrical network with internal combustion engine from device.Structure can be such, i.e. handles
The control handle 156 being used as shadowing elements of key 116 allows to open hood 110.
Can also alternatively set, control handle 156 hinders engine compartment cover hood 110 in other words
Open yaw motion or similar motion so that although can be by handling unlatching element according to Fig. 9
Operator region 154 handle unlatching element, but hood open additionally requirement
Extracting manipulation key 116 from the keyhole of battery separators 118, this is the most only by Fig. 9
Failure state in can carry out.
Manipulation key 116 is extracted in Figure 10 and 11 display in the keyhole from battery separators 118
Configuration state afterwards.Then can open without barrier after handling unlatching element 152 and send out
Motivation hatchcover hood 110 in other words.Open element 152 the most permissible
It is configured to joystick member.Figure 12 shows, can be how by means of handling key 116 manipulation unlatching
Element 152, mode is: the control handle 156 being used as shadowing elements is led through space 112
Enter in the inner chamber region after space and extrude the operator region 154 opening element 152.
This causes the unblock of blocking mechanism 150 so that then can open without problems engine compartment cover or
Person says hood 110.
If hood is opened, then handle key 116 and can be inserted into again battery separators
In the keyhole of 118, in order to such as can by manipulation key 116 being adjusted to activation position
Start internal combustion engine.The control handle 156 being used as shadowing elements about space 112 is configured to,
Making the hood when handling key 116 and being arranged on activation position is to close and can borrow
