An output shaft (1) is arranged in a transmission shell of the automotive electronic gear shifting device, an outer gear ring (7) and a P gear are arranged on the output shaft (1), a locking pawl (2) is arranged in the transmission shell, an electronic gear shifting rod is arranged to be a structure which can push the locking pawl (2) to rotate from the initial position to be clamped into a clamping groove formed in the P gear, an unlocking part (3) arranged under the locking pawl (2) is connected with one end of a pull wire (4), and the other end of the pull wire (4) extends out of the transmission shell. According to the automotive electronic gear shifting device, the structure is simple, and the cost is low; when an automobile is in a special situation, the locking pawl can be effectively and rapidly pushed to be separated from the P gear to unlock the P gear of a transmission, therefore, the transmission can conveniently and rapidly enter the neutral gear (the N gear) position from the P gear position, and then safety of the whole automobile is guaranteed.
Description
Technical field
The invention belongs to shifting vehicle gearbox control parts technical field, more specifically, it is to be related to a kind of automobile electricity
Sub- gearshift.
Background technology
At present, on market, the gear level of the electric gear change device of variator has various ways, such as: knob, button etc..
The principle of electron gear shifting bar is that electron gear shifting bar is connected with variator, employs more safe, efficient Electronic Control pattern, saves
Remove the shift mode of traditional mechanical formula, all replaced using electronic signal.The advantage of electric gear change with: 1. lifted person of outstanding talent
China's sense, technology sense.Compare traditional mechanical lever, the technology of electronics lever is also relatively very new, is also mainly used in luxury car, it
Appearance undoubtedly to allow the class of automobile be lifted many；2. protect driver.The gearshift mistake of driver, maloperation can be sentenced by computer
Disconnected, conclude whether variator can be caused to damage simultaneously, thus preferably protection variator and the bad gearshift correcting driver
Custom；3. gearshift is lighter.Compare mechanical lever, the dynamics that car owner uses in electric gear change is lighter, serious forgiveness is higher,
Infringement to variator is less, also because eliminating the gearshift of mechanical type lever, there is provided an easier operation
Mode.But, existing electric gear change device has the shortcomings that certain, because existing electric gear change variator is only in electromotor
Under starting state, ecu diagnosis has no problem and lower just can work.And when electromotor cannot start, it is provided with electric gear change device
Variator cannot from p gear (parking position switch) position be switched to neutral (n shelves) position, so in particular cases will at some
Bring huge hidden danger.For example, 1, when car load carries out oil consumption test, pretreated car load need to be misfired in electromotor
On propulsion trial rotary drum under state, but now vehicle is in p file location, can only transport on rotary drum by plant equipment by automobile,
Mobile intensity is big, wastes time and energy.2. after there is flood, the water inlet of the inlet manifold of vehicle, electromotor will stop working, and now electromotor is not
Can light a fire again, otherwise electromotor may be scrapped.Vehicle belongs to flameout state in this state, and can not be by parking gear
Put and be linked into neutral gear position and wait for rescue it is impossible to shift vehicle onto home.Can also be incited somebody to action by trailer as run into precursor vehicle
Front-wheel lifts and drags vehicle away, but runs into four-wheel drive cars, even if trailer also has had no way, because variator is now in locking
Death situation state.The presence of above-mentioned technical problem is so that there is more obvious hidden danger in the variator of vehicle.
Content of the invention
The technical problem to be solved is: for the deficiencies in the prior art, provide a kind of structure simple, by
Urgent parking unlocking feature is increased on automotive electronics gearshift, is in particular cases in automobile, can effectively, fast promote
Crevis departs from p shelves gear, realizes the unblock to variator so that variator enters neutral (n shelves) position from p file location,
So that it is guaranteed that the automotive electronics gearshift of car load safety.
Solve the problems, such as techniques discussed above, the technical scheme that the present invention takes is:
The present invention is a kind of automotive electronics gearshift, and described automotive electronics gearshift includes case of transmission, electricity
Sub- gear level, setting output shaft in described transmission case body, setting external toothing and p shelves gear, case of transmission on output shaft
Inside also set up crevis, described electric gear change bar is configured to promote crevis to rotate from initial position and snap in p
Structure in the draw-in groove of shelves gear, described crevis lower position arranges unlocking feature, and unlocking feature is with bracing wire one end even
Connect, the bracing wire other end extends case of transmission.
Described unlocking feature includes part rod member, locking cam, and described part rod member is with case of transmission activity even
Connect, locking cam is configured to be resisted against the structure of crevis lower position, locking cam with can pull locking cam
The bracing wire one end rotating connects.
When extending bracing wire one end of case of transmission and pulling, bracing wire and locking cam are configured to pull locking cam
The structure rotating, when described bracing wire pulls locking cam rotation, locking cam is configured to promote crevis to exit p shelves
The structure of the draw-in groove on gear.
Described crevis is flexibly connected with case of transmission by ratchet rod member, described crevis and return bullet
Spring connects, and return spring is configured to apply structure on crevis for the pulling force.
After described locking cam promotes crevis to exit the draw-in groove in p shelves gear, return spring is configured to apply
Plus pulling force pulls crevis to leave p shelves gear and return to the structure of initial position.
One end that case of transmission is extended in described bracing wire connects draw ring, and draw ring is arranged on car steering chamber interior.
When described bracing wire pulls locking cam to promote crevis to exit the draw-in groove in p shelves gear, automatic transmission sets
It is set to and exit p file location and be in the structure of neutral gear position.
Using technical scheme, following beneficial effect can be obtained:
Automotive electronics gearshift of the present invention, cannot open mainly for some in particular cases vehicle motors
Dynamic, lead to variator cannot be linked into neutral gear position from parking file location and design, need vehicle from parking under special circumstances
When gear is linked into neutral, by pulling bracing wire, bracing wire pulls unlocking feature (i.e. urgent parking unlocking feature) action, and unlocking feature is made
On crevis, promote crevis to depart from the draw-in groove of p shelves gear, release the locking to p shelves gear, at this moment vehicle is permissible
It is linked into neutral, that is, achieve and the purpose that variator is linked into from parking shift neutral reached, such that it is able to root by accessory
According to needing to be moved easily vehicle, it is to avoid because in particular cases cannot mobile vehicle and the danger that causes and loss.Said structure,
It is not only simple in structure, easy to operate, and also less investment can achieve it is only necessary to improve on existing electric gear change device basic
Function.Automotive electronics gearshift of the present invention, structure is simple, low cost, by increasing on automotive electronics gearshift
Step up anxious parking unlocking feature, be in particular cases in automobile, can effectively, fast promote crevis to depart from p shelves gear,
Realize the unblock of the p shelves to variator so that variator conveniently and efficiently can enter neutral (n shelves) position from p file location, from
And guarantee car load safety.
