Description
Technical field
The invention belongs to technical field of automobile parts, and in particular to a kind of switching device for preventing maloperation.
Background technology
With being continuously increased for automobile function configuration, more electric switches are needed on automobile, due to Bus inner layout space
Limited, a switch button often integrates multiple functions, i.e., realizes difference in functionality by different operation directions.Work as human hand
When operation direction is not very accurate, switch may be pressed to two operation directions simultaneously, is designed if switching no anti-misoperation,
It may result in switch and be also turned on two functions in operation, make troubles to driver and passenger, in some instances it may even be possible to dangerous.
For example, with dialled before an idler wheel, it is rear dial and lower by realizing three functions, when front and rear jog dial, before and after making idler wheel
Rotation rotates idler wheel, it is necessary to apply downward power to idler wheel to obtain enough frictional force, will when downward power is larger
Make just to trigger two functions simultaneously at this time by function under idler wheel triggering.
Utility model content：
The defects of in order to overcome above-mentioned background technology, the present invention provide a kind of switching device for preventing maloperation, convenience
Height, accuracy rate are high.
In order to solve the above-mentioned technical problem used technical solution of the invention is：
A kind of switching device for preventing maloperation including wiring board, the first switch and the second switch to be triggered to be triggered, is gone back

As a kind of preferred embodiment of the present embodiment, two /Vs including being symmetrically disposed on 4.1 both sides of /V frizzen
Bar 4.2, respectively with two gag lever posts, 4.2 corresponding two the second perforates 3.3 and two the second limit holes 2.3.
As a kind of preferred embodiment of the present embodiment, treat respectively including two the second switches 1.2 to be triggered and with two
The corresponding movable mandril 2.2 of trigger switch, respectively with two 2.2 corresponding compression bars 3.2 of movable mandril.
On pressing direction, switching manipulation block 4 and the matching relationship of switch mounting base plate 2 are：Operating block 4 is from external force shape
Under state, elastic component 6 supports operating block 4, and the gag lever post 4.2 is made to be located at outside second limit hole 2.3, and the two of operating block 4
A gag lever post 4.2 does not put in the second limit hole 2.3 of switch mounting base plate 2, and /V frizzen 4.1 stretches into the first limit hole 2.1
In；After the handle 4.4 for pressing switching manipulation driving lever, gag lever post 4.2 also enters in the second limit hole 2.3.
It is stirred front and rear on direction, switching manipulation block 4 is with 2 matching relationship of switch mounting base plate：Switch mounting base plate 2
First limit hole 2.1 is cross recess shape, in 3.5 vertical direction of shaft, the length of the first limit hole 2.1 is touched more than /V
The length in 4.1 section of bar is sent out, therefore the /V frizzen 4.1 of switching manipulation driving lever can be in the first limit hole 2.1 along shaft
3.5 directions rotated are moved back and forth；
Two the second limit holes 2.3 of switch mounting base plate 2 are square holes, after handle 4.4 is pressed, are set in /V and touch
The spring 6 of hair bar 4.1 is compressed, and /V frizzen 4.1 is waited to touch through the first perforate 3.1, the first limit hole 2.1, pressing first
Hair switch 1.1；And two gag lever posts 4.2 of switching manipulation block 4 respectively enter two the second limit holes 2.3 at this time, due to
In 3.5 vertical direction of shaft, the length of the second limit hole 2.3 is identical with the length in 4.2 section of gag lever post, therefore entire switch behaviour
Back-and-forth motion along 3.5 direction of shaft cannot be carried out by making block 4, therefore when carrying out pressing operation, operating block 4 can not be carried out at the same time
Front and rear stirs operation.
In the handle 4.4 of front and rear toggle switch operating block 4, /V frizzen 4.1 drives rotation shifting block 3 along shaft 3.5
Rotate, compression bar 3.2 can be pressed into one end of the corresponding movable mandril 2.2 in position on pedestal 2 with rotating, movable mandril 2.2 it is another
The second switch 1.2 to be triggered of one end pressing；For operating block 4 under external force state, elastic component 6 supports operating block 4, gag lever post 4.2
Outside the second limit hole 2.3, so rotation shifting block 3 could be rotated along shaft 3.5, and gag lever post 4.2 is because 4 quilt of operating block
It stirs forward or backward, so gag lever post 4.2 can stagger with limit hole position forward or backward, and at this point, switching manipulation
Block 4 cannot also be pressed downwards.
When carrying out pressing operation, switching manipulation block 4 is under small-startup stroke, about 0.3mm, and gag lever post 4.2 is put into the
In two limit holes 2.3, gag lever post 4.2 cannot move back and forth in the second limit hole 2.3 at this time, so switching manipulation block 4
It is stirred before and after being just restricted from, so just realizes the function that switch is stirred before and after the lower mistiming operation by action, formation is stirred
Position-limit mechanism；
When stirring operation before and after progress, when switching manipulation block 4 it is smaller stir angle under, about 0.5 °, gag lever post 4.2 is just
Stagger the second limit hole 2.3, and switching manipulation block 4 cannot press down at this time, and /V frizzen 4.1 be can be first
Moved back and forth in limit hole 2.1, so just realize switch in front and rear stir under maloperation by function, formed pressing /V
Mechanism.
It should be appreciated that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
