Detailed description of the invention
With reference to figure 1-5, the power actuated vehicle comprising principle of the present invention can be seen best.For convenience's sake, use and left part, right part, front portion or any of rear portion are quoted, and such quoting is defined as standing on rear view of vehicle, such as in the left side of accompanying drawing 1-3, and be conceived to the front end of normal travel direction.In the U.S. owing to being configured to for this definition in the vehicle of traditional operation, driver side will be positioned at the left side of vehicle, and occupant side will on the right side of vehicle simultaneously.As shown in the drawing, although the present invention preferably with such as SUV (sport utility vehicle) (SUV) and the power actuated vehicle conbined usage with straight flange vehicle in fact that transboundary car is such, person of ordinary skill in the field by recognize such other vehicle of such as pick-up truck or roadlice also can be equipped with below air extractor in greater detail.Person of ordinary skill in the field also will recognize any increase that the present invention can be used to alleviate in fact air pressure in car cabin, the closedown of car door all vehicle windows that such as can run in vehicle are closed.
Provide vehicle 10, this vehicle 10 is with the vehicle frame 11 being arranged on vehicle 10 defines the car body 12 of driver and passenger accommodation 15.Passenger accommodation 15 is typically provided with multiple vehicle window 16, and these vehicle windows 16 can optionally rise or fall to control air-flow or extraneous air enters passenger accommodation 15.When not opening other vehicle window 16 any when opening the so single vehicle window of such as front passenger vehicle window 17, the vehicle moved forward under given minimum running velocity can run into low frequency pulse.This low frequency pulse is commonly called wind disturbance and it causes by entering the air that vehicle 10 attempts balancing each other with the air be filled in passenger accommodation 15.As shown in the prior art view of Fig. 2, this single vehicle window 17 opened provides air and enters and the single-pathway leaving passenger accommodation 15.
In order in the inlet air flow path not needing to provide when opening vehicle window 16 extraly by passenger accommodation 15, air extractor 20 is arranged in passenger accommodation, and it is preferably located in the rear portion of vehicle, in the rear door 13 of the center such as after licence plate 14.The center of air extractor 20 does not consider that the sidepiece of the single vehicle 10 at vehicle window 17 opened provides from the isometric flow path of relative vehicle window 16.Select as one, this air extractor 20 can be arranged on the side at the rear portion of vehicle 10, after all car light fixed parts 19 as shown in Figure 10.Also air extractor 20 can be arranged in the chassis of vehicle.Correspondingly, person of ordinary skill in the field contributes to making internal air exhausting equal to enter the amount of air of passenger accommodation 15 by having recognized the need to arrange when air extractor 20 exists with convenient wind disturbance situation.
Air extractor 20 comprises the car body through vehicle---such as through rear door 13---and the extraction opening 22 of formation.This extraction opening 22 is closed by moveable closing feature 25, and this closing feature 25 is connected to and causes closing feature 25 to move also thus open and close the actuator 27 of extraction opening 22 in a selective way.In the first embodiment of the air extractor 20 shown in Figure 4 and 5, closing feature 25 is for being arranged on linear moveable flat components on slide rail 26 to help the perpendicular movement of closing feature 25 to open and close extraction opening 22.The cross-sectional area opened of extraction opening 22 optionally can be changed by the height of closing feature 25 movement.Such as, iff there is slight wind disturbance situation, then mobile closing feature 25 that can be only slight, but violent wind disturbance situation will cause the larger perpendicular movement of closing feature 25 and thus cause the size of larger opening 22.Correspondingly, do not need the fan that supplements from passenger accommodation extracting air to discharge air by extraction opening from vehicle.
Show the selectable representative structure for closing feature 25 in figures 6 to 8.In figure 6, transverse pivot 28 around level generally installs closing feature 25 pivotally, such as along the upper limb of closing feature 25, the retraction of actuator 27 and extension is made to cause the pivoting action of the correspondence of closing feature 25 to open and close extraction opening 22 in a variable manner.Similarly, in fig. 8, closing feature 25 is installed pivotally to move, so that closing feature 25 is vertically removable to open and close extraction opening 22 along the camber line around pivot 29 for the longitudinal pivot 29 around level generally.In the figure 7, closing feature 25 is the venetian blind types with interconnective single louver, so that actuator 27 causes the pivoting action of all louvers to open and close extraction opening 22 to the connection of top louver 25a.
As shown in figs. 1 and 3, air stream leaves from vehicle 10 can leave from rear door 13 by allowing the air stream that leaves and flow around licence plate 14.Streamlined reefer housing (deflector hood) 24 also can be used for limiting the chance entering the rear side of extraction opening 22 from the rainwater of vehicle 10 outside and dust.Further as depicted in figure 10, similar air extractor 20 can be encapsulated in the car body after respective rear vehicle lamp fixed part 19, as in Figure 10 embody, to guide the air stream left can directly around car light fixed part 19.Preferably, be especially on the inside of rear door 13 can be ornamental filter screen 23 described in Fig. 4 and 11, the opposed end of extraction opening 22 can be arranged on to protect air extractor 10.
Control mechanism 30 is encapsulated in passenger accommodation 15 to sense the existence of wind disturbance situation and to initiate to open the operation of the actuator 27 of extraction opening.Control mechanism 30 can comprise sensor 32, and it produces and causes the signal 33 that actuator 27 opens or closes extraction opening 22.When vehicle 10 is just to be greater than the speeds of threshold velocity, this sensor 32 can be exercisable with ECU electronic control unit 35 cooperating syringe, and what---typically be single vehicle window 17---to sense the vehicle window 16 of predetermined number opens.These minimum parameter and the minimum running velocity of the single vehicle window opened inform the existence of wind disturbance situation with signal.As a result, activator switch 36 and can be the actuator 27 such as open closed parts 25 of screw actuator or worm gear actuator.The height of closing feature 25 can change with the running velocity of vehicle 10.Running velocity is larger, and it is higher that closing feature rises.To be changed to another from a vehicle with rear drive for what establish the parameter of the existence of wind disturbance situation and air extractor 20.Therefore, therefore self-defined control mechanism 30 is also reflected the geometry of vehicle.Such as, on vehicle " A ", minimum wind disturbance situation can be that a vehicle window is opened and the parameter of the minimum running velocity of 60MPH, and on vehicle " B ", to put down and there will be wind disturbance under the minimum running velocity of 40 MPH due to the geometry of vehicle at two vehicle windows.Correspondingly, use these wind disturbances that the parameter started when occurring is come Programmed control mechanism 30.
Sensor 32 also can be mounted in the pressure sensor (pressure transducer) 38 on the such appropriate location of such as instrument carrier panel (not shown) in passenger accommodation.When pressure sensor 38 detects the rising of the air pressure in pressure pulsation or passenger accommodation or reduces, produce signal to activate the operation of actuator 27 and to provide the inlet air flow path through passenger accommodation 15.The height of closing feature 25 can change with the sustainable existence of pressure pulsation, and such as, closing feature 25 is at the front opening extraction opening 22 of pressure pulsation stopping.Only when single vehicle window 17 is opened to produce wind disturbance situation, pressure sensor 38 also can couple pressure sensor 38 can be operated with ECU electronic control unit 35.
When eliminating wind disturbance situation, if such as close all vehicle windows 16 or open another vehicle window 16, close extraction opening 22 with signal notice actuator 27.Therefore, air extractor 20 is only exercisable when wind disturbance or wind disturbance situation exist.Under other situations all, closing feature 25 closes extraction opening 22.In addition, when car speed declines or when dissipating when pressure pulsation, operate actuator 27 can narrow to make the cross-sectional area of extraction opening 22, be placed on optimum position to make closing feature 25.The pulse monitoring of wind disturbance situation and the wind disturbance situation and the operation for air extractor 20 that exist and the parameter set up compare the operated control of the closedown or continue being provided for air extractor 20 being opened.Pulse monitoring can be that millisecond is on the time cycle of second.
When all vehicle windows of vehicle are all closed, closed door also can produce the increase of air pressure, and when car door is just closed, pressure sensor can detect the increase of this air pressure.Under these circumstances, pressure sensor 38 sends a signal to actuator 27 with open closed parts 25 provides by the inlet air flow path of extraction opening 22 to prevent the pressure in passenger accommodation 15 from increasing and to be convenient to the closedown of car door.Select as one or additional, whether the vehicle window that control mechanism 30 can sense in when car door opening and passenger accommodation 15 closes, the increase of air pressure that this situation will allow when car door is closed subsequently in passenger accommodation 15.Therefore, control mechanism 30 it is expected to cause situation that air pressure raises and before car door is just closed open closed parts 25, or when just at closed door and pressure sensor 38 senses open closed parts 25 when air pressure increases.The peristome of extraction opening 22 prevents air pressure to gather and allows car door to close easily.
Be in operation, the situation lower pumping device 20 closing extraction opening 22 at closing feature 25 keeps not running until control mechanism 30 senses the existence of wind disturbance situation, such as ECU electronic control unit 35 records only vehicle window 17 and to have opened and vehicle moves forward with the speed being greater than threshold velocity, or records the existence of the pressure pulsation from the single vehicle window 17 opened as a kind of pressure sensor 38 of selection.At this moment, actuator 27 automatically runs to move closing feature 25 and open extraction opening 22 and manufactures flow path for the air by passenger accommodation 15 movement.The respective position of the closing feature 25 corresponding with the area of the extraction opening 22 opened and wind disturbance pulse can be alleviated by the amount of air of passenger accommodation 15 movement.When eliminating wind disturbance situation, such as open another vehicle window 16, the vehicle window 17 that closedown is opened or car speed are reduced under minimum threshold velocity, then control mechanism 30 operate actuator 27 closes extraction opening 22 to keep not running until again sense wind disturbance or wind disturbance situation.
Should be understood that to describe and illustrate for explaining that the change that the details of essence of the present invention, material, step and parts are arranged will occur and be made on the basis of the reading to the specification sheets in principle of the present invention and scope by person of ordinary skill in the field.Aforesaid specification sheets illustrates the preferred embodiments of the present invention; But the concept based on specification sheets may be used for other embodiment without departing from the scope of the present invention.
