Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
In the disclosure, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower " is typically referred to corresponding
It is defined on the basis of the drawing of attached drawing, " inside and outside " refers to the inner and outer of corresponding component profile.
In conjunction with Fig. 3, to achieve the goals above, the disclosure provides a kind of air pressure resistance driving switch, including shell 2, in shell
Electrical connection module and mandril action piece are set gradually along axial direction in body 2, mandril action piece includes the mandril set gradually along axial direction
Component 3 and action piece；Action piece is sealed in shell 2 by being positioned close to the sealing ring 10 at 3 end of push rod component.Existing skill
Action piece in art realizes the intracorporal sealing of chamber by the plain cushion structure of gasket, when odd-side is in high-grade position, mandril group
Part 3 is not compressed, but since push rod component 3 is in air pressure environment, compressed air, which acts on, can generate axial direction on gasket 4
Trigger force, cause switch to malfunction, the disclosure is disappeared that is, by way of radial seal by the alternative design of sealing ring 10
Except sealing element generates axial trigger force after by gas pressure, to effectively solve the problems, such as that height gear switch malfunctions.Meanwhile
The contact area of sealing ring 10 and action component after change reduces, and hardly contacts with push rod component 3, not only saves sealing element
Materials, while the service life of sealing element 10 can also be improved.
In addition, the influence of the sealing effect of sealing ring 10, reduction air pressure to it in order to further increase, in sealing ring 10
Baffle 9 is also set up between push rod component 3, and the pressure of axial support force and blocking air pressure is mainly provided to sealing ring 10, is prevented
The active force axial to push rod 5 of sealing ring 10.
For example, further including the insulator 6 being fastened on along axial direction in shell 2 in embodiment of the disclosure, it is preferred that absolutely
Edge body 6 is arranged in the shell between electrical connection module and mandril action piece, and action piece is push rod 5, wears on insulator 6 along axial direction
If push rod 5,5 one end of push rod is held out against with push rod component 3, and the other end of push rod 5 is electrically connected with electrical connection module contact；In push rod
5 with sealing ring 10 is set in the shaft shoulder of the insulator 6 of the contact jaw of push rod component 3.When compressed air acts on sealing ring 10
When, due to the shaft shoulder axial restraint of 10 insulated body 3 of sealing ring, eliminates sealing ring 10 and generate axial touching after by gas pressure
It has an effect, while can also have the function that sealing.It is also possible that in the shaft shoulder of the insulator 6 between sealing ring 10 and push rod component 3 also
Baffle 9 is set, axial fixed force is provided to sealing ring 10, further increases the sealing effect of sealing ring 10, reduce air pressure pair
Its influence avoids falling off for sealing ring 10.
In addition, in embodiment of the disclosure, the other end of push rod 5 is fixedly connected with movable contact spring 7, and electrical connection module includes
The push rod component 3 of static contact 8 and binding post 1, switch is toggled mechanism urges and is axially moved, and then pushes push rod 5
The contact for driving movable contact spring 7 and static contact 8, realizes switching on and off for inner contact, is finally embodied between two binding posts 1
Electrical on-off.
Push rod component 3 includes the mandril for being threaded through 2 end of shell and the acrosome being embedded in shell 2, and the diameter of acrosome is big
In the diameter of mandril.Acrosome is mainly used for acting on action piece, and mainly transmitting acts mandril.
Preferably, the sealing ring 10 of the disclosure is O-ring seal.
According to the second aspect of the disclosure, a kind of gearbox, including driving switch are also provided, the driving switch is
Air pressure resistance driving switch described in the disclosure.
In terms of according to the third of the disclosure, a kind of automobile, including gearbox are also provided, the gearbox is the disclosure
The gearbox.
The ingehious design of disclosure proposed adoption sealing ring 10, when gearbox is in low gear position, push rod component 3 is touched
Hair mechanism urges are simultaneously axially moved, and then push rod 5 is pushed to realize switching on and off for inner contact, are finally embodied in two
Electrical on-off between binding post 1.When gearbox is in high-grade position, trigger mechanism does not push push rod component 3, at this time insulator
Have a compressed air in auxiliary box cylinder in 6 cavitys formed with shell 2, compressed air act on sealing ring 10 after not
The axial force to push rod 5 can be generated, to effectively solve the problems, such as that height gear switch malfunctions.
The preferred embodiment of the disclosure is described in detail in conjunction with attached drawing above, still, the disclosure is not limited to above-mentioned reality
