Abstract
The utility model relates to a vehicle interior pressure controlling device, which comprises a controller, a vehicle door induction switch, a device for measuring the pressure difference between vehicle interior and exterior, and a vacuum device, and further comprises a vacuum tube arranged between a vehicle interior space and a vacuum device. An electromagnetic valve is arranged on the vacuum tube; the vehicle door induction switch, the device for measuring the pressure difference between vehicle interior and exterior and the electromagnetic valve are electrically connected with the controller. When a vehicle door is closed instantly, the exterior pressure and the interior pressure of the vehicle basically keep consistent, so that the comfort in traveling is improved.
Description
Technical field
The utility model relates to a kind of interior pressure control setup that the pressure of automotive interior is controlled of being used for.
Background technology
Along with the continuous development of society, car becomes people's the vehicle just gradually, and the user is also more and more higher to the car performance demands, particularly to the requirement of traveling comfort.When automotive technology is constantly progressive, the sealing property of car is also become better and better, yet some problems have also been brought thus, when our closed door, the instantaneous rising of pressure meeting in the car, occupant ear-drum moment this moment can produce a kind of sensation of discomfort, mainly since the car external and internal pressure do not wait and do not cause.
The utility model content
The purpose of this utility model is at above deficiency, and a kind of interior pressure control setup is provided, and in the moment of closed door the car external and internal pressure is consistent substantially.
The utility model provides a kind of interior pressure control setup, comprise controller, car door inductive switch, car inside and outside differential pressure measurement mechanism and vacuum, also comprise the vacuum lamp that is arranged between interior space and the described vacuum, also be provided with electromagnetic valve on the described vacuum lamp, described car door inductive switch, car inside and outside differential pressure measurement mechanism and electromagnetic valve are electrically connected with described controller.
The utility model interior pressure control setup can be controlled the air of vacuum in the transient absorption car of closing of the door by controller, thereby can effectively suppress the interior pressure rising, reduce the car inside and outside differential pressure, the occupant can not produce uncomfortable sensation, improved the traveling comfort of riding, and this structure Design has taken into full account machine up and electric elements, and small investment is easily carried out industrialization.
Description of drawings
Fig. 1 is the structure principle chart of interior pressure control setup of the present invention.
The specific embodiment
The specific embodiment of the present utility model can further specify by the following detailed description.
Interior pressure control setup as shown in Figure 1, comprise controller 11, car door inductive switch 6, car inside and outside differential pressure measurement mechanism and vacuum, also comprise the vacuum lamp that is arranged between interior space (not shown) and the vacuum, also be provided with electromagnetic valve 5 on the described vacuum lamp, described car door inductive switch 6, car inside and outside differential pressure measurement mechanism and electromagnetic valve 5 are electrically connected with described controller 11.
Controller 11 can adopt electronic control unit (ECU), car inside and outside differential pressure measurement mechanism adopts respectively interior pressure sensor 9 and the car external pressure sensor 10 that Che Nei and car external pressure are measured, ECU collect behind the pressure of sensor can according to pressure reduction control vacuum whether needs absorb air in the car.Vacuum comprises vacuum reservoir 3, it is communicated with interior space by vacuum lamp, on vacuum lamp, also be provided with electromagnetic valve 5, what connect interior space and electromagnetic valve 5 is first vacuum lamp 8, what connect electromagnetic valve 5 and vacuum reservoir 3 is second vacuum lamp 4, when electromagnetic valve 5 was opened, first vacuum lamp 8 and second vacuum lamp 4 were communicated with interior space and vacuum reservoir 3.Electromagnetic valve 5 is electrically connected with electronic control unit (ECU), thus the switching that ECU can control electromagnetic valve 5.
Whether car door is closed the device of responding to is car door inductive switch 6, and car door inductive switch 6 is installed near the vehicle body of car door and vehicle body hinged place, and during closed door, car door inductive switch 6 contacts with car door.Car door inductive switch 6 is electrically connected with ECU, thereby ECU can collect the closing of the door information that car door inductive switch 6 is sensed.
End that is positioned at interior space at first vacuum lamp 8 that connects interior space and electromagnetic valve 5 is provided with a noise silencer 7, when first vacuum lamp 8 absorbs in the cars air, can reduce noise.
Working process of the present utility model is as follows:
During closed door, when car door inductive switch 6 with after vehicle body contacts, ECU receives the signal of car door inductive switch 6, and send instruction, electromagnetic valve 5 energisings are opened, like this, just entered vacuum reservoir 3 by the air that constantly compresses in the car, thereby slowed down the rising of interior pressure by first vacuum lamp 8 and second vacuum lamp 4.
Behind the closed door, when the force value of interior pressure sensor 9 and car external pressure sensor 10 was identical, electronic control unit (ECU) sent instruction, and electromagnetic valve 5 outages are closed, and air just no longer enters vacuum reservoir 3 in the car.The car external and internal pressure has kept unanimity substantially in the whole process of closed door, has improved occupant's traveling comfort greatly.
The foregoing description only is for the utility model is described, rather than, those skilled in the art will appreciate that without departing from the inventive concept of the premise that the utility model also has many modification to restriction of the present utility model.
