In multiple, one magnetic control component 44 of setting on each throttle orifice 421；Or throttle orifice 421 is the biggish through-hole in aperture, throttle orifice
One magnetic control component 44 is set on 421.In addition, valve rod 43 offers fairlead 431 along its axis, the lead a of coil 442 is worn
It is located in fairlead 431, and is pierced by from valve rod 43 after being pierced by valve body 41 and is connect with power supply circuit (not shown), the power supply
Circuit can be the electrical control circuit of existing coil.In addition, piston 42 is made by flexible material, such as silica gel, rubber, make to live
Plug 42 itself has leakproofness, while valve body 41 is provided with sealing element at the position that valve rod 43 passes through and realizes sealing, the sealing element
The flexible of valve body 41 is not influenced, such as the sealing element can be with O-ring, silica gel sheath etc..
In being pointed out that the present embodiment as a kind of alternative embodiment, only it is exemplary and enumerates magnetic control group
A kind of layout type of part 44, however, the present invention is not limited thereto, it should be understood that, the quantity of magnetic control component 44, geomery, cloth
The parameters such as office position, magnetic field strength are unrestricted, carry out solid-liquid form to the magnetorheological fluid in throttle orifice 421 as long as can be realized
Conversion.For example, the position of permanent magnet 441 and coil 442 can be exchanged in some alternative embodiments of the present invention.
Further, parking device further includes the inductor for incuding the meshing state of spreadet spreadet wheel 10 and pawl 20
50 and the controller (as do not show) that is electrically connected with inductor 50, controller electrically connect with driver 30 and coil 442 respectively
It connects.In the present embodiment, inductor 50 can be angular transducer (such as Hall angular transducer), and angular transducer may be selected
The meshing state that spreadet spreadet wheel 10 and pawl 20 are incuded by the corner of monitoring brushless motor and/or pawl 20, works as locking tooth
When wheel 10 and pawl 20 engage, the corner of brushless motor and/pawl 20 is maximum.In some alternative embodiments of the present invention, sense
Answer device 50 that one contact sensor can also be set for multiple contact sensors in each teeth of spreadet spreadet wheel 10, in this way when
It is sensed when engagement because of contact；Or inductor 50 can also be range sensor, arrive locking tooth by induction pawl 20
The distance at 10 centers is taken turns to incude meshing state；Or inductor 50 can also be the pressure sensing being arranged on engaging section 22
Device, to incude meshing state by senses change in pressure.In addition, controller can be miniature CPU, single-chip microcontroller or ECU.
It is corresponding, the course of work of the parking device in the present embodiment are as follows: when controller receives parking signal,
Make driver 30 that pawl 20 be driven to swing towards spreadet spreadet wheel 10, and coil 442 is made to be powered, so that engaging section 22 is in scalable
State, in this way when engaging section 22 is encountered spreadet spreadet wheel 10 but do not engaged also, will not stuck and excessive wear, when engaging section 22 with
After spreadet spreadet wheel 10 engages, inductor 50 is sensed, controller closes driver 30 and coil 442 powers off, and pawl 20 is in rigid
Character state is engaged with spreadet spreadet wheel 10, realizes parking.
To sum up, the parking device in the above embodiment of the present invention uses magnetic control component 44 by being arranged on pawl 20
The buffer gear 40 cooperated with magnetorheological fluid 45 makes pawl 20 combine and separate with 10 flexibility of spreadet spreadet wheel, avoids because mechanical rigid
Property combine generated stuck and Fast Wearing, guarantee P grade it is easy to hang upper and cancel, avoid generating mechanical percussion when hanging P gear and make an uproar
Sound.
Referring to Fig. 4, the structural schematic diagram for the parking device showing in second embodiment of the invention, in the present embodiment
Parking device and first embodiment in parking device it is more or less the same, the difference is that:
Buffer gear 40 further includes the nitrogen accumulator 46 being arranged in valve body 41, and nitrogen accumulator 46 is located at valve rod 43
The opposite sides of piston 42.The nitrogen accumulator 46 works as engagement for realizing flexible buffering and reset response to engaging section 22
When stretching under drag effect of the portion 22 in engagement process, piston 42 pushes magnetorheological fluid 45, forms hydraulic pressure, the pressure of liquid
Power can be stored in the gas of nitrogen accumulator 46, when hydraulic pressure decline, push piston to release in the pressure of accumulator gas
Exoergic amount, until identical as system pressure or move to range.
It should be pointed out that some technologies of device provided by second embodiment of the invention, realization principle and generation
Effect is identical with first embodiment, and to briefly describe, the present embodiment does not refer to place, can refer in corresponding in first embodiment
Hold.
Another aspect of the present invention also proposes a kind of automobile, is electrically connected including vehicle control device and with vehicle control device
Parking device and vehicle status sensor, parking device are the parking device in above-mentioned first or second embodiments, vehicle control
Device processed is used for the car status information acquired according to vehicle status sensor, and whether judgement currently meets P gear parking condition, if full
The sufficient then pawl of parking device is engaged with spreadet spreadet wheel realizes parking；If not satisfied, then pawl is separated with spreadet spreadet wheel.
Wherein, vehicle control device can be shared with the controller of parking device, such as be ECU, or phase intercommunication
Two independent control devices of news.In some alternative embodiments of the present invention, vehicle status sensor can be gear position
It sets sensor, service brake pedal position sensor, infrared human body sensor, Hall angle and passes device, velocity sensor, gyro sensors
One or more in device, power management module etc., these sensors can be communicated by CAN bus with vehicle control device.Phase
Corresponding, parking control process can be with are as follows: velocity sensor detects transmission output speed, if degree speed value is setting safe model
In enclosing, detect whether automobile stops working by power management module, if it is flame-out, then would judge that P grades are by gear positions sensor
It is no to perform, if be not carried out, whether in the car again by infrared human body sensor detection driver, if it was not then
Judgement meets P gear parking condition, realizes automatic parking.
To sum up, the automobile in the above embodiment of the present invention, by pawl be arranged using magnetic control component with it is magnetorheological
Liquid cooperation buffer gear, make pawl with spreadet spreadet wheel flexibility in conjunction with separate, avoid because mechanical rigid combination caused by card
Dead and Fast Wearing guarantees P grades of easy to hang upper and cancellations, avoids generating mechanical beat noise when hanging P gear.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
