Description
Technical Field
The invention relates to the field of vehicle door control, in particular to a method for controlling closing force of a vehicle door and a vehicle.
Background
The passenger door system that uses mainly comprises joint strip 1, door plant 2, rocking arm 3, door pump 4, follower 5 and lock 6 as shown in fig. 1, and this system uses atmospheric pressure to drive door pump 4 and works, and the front side of rocking arm 3 of passenger door links to each other with door plant 2, and the bottom links to each other with door pump 4, and when passenger door needs to be closed, door pump 4 drives rocking arm 3 clockwise rotation, and then drives door plant 2 and close, and simultaneously follower 5 provides inwards pulling force to the passenger door, makes door plant 2 can close smoothly. When the passenger door is closed, the door pump 4 provides an upward force to the rotating arm 3, and the rotating arm 3 drives the door plate 2 to move upwards, so that the passenger door can be locked smoothly. When the passenger door needs to be opened, the door pump 4 provides downward force for the rotating arm 3, the rotating arm 3 drives the door plate 2 to move downwards, then the door pump 4 drives the rotating arm 3 to rotate anticlockwise, and then the door plate 2 is driven to be opened, meanwhile, the follow-up rod 5 provides inward pulling force for the passenger door, so that the door plate 2 can be smoothly opened, and air pressure tightens the door plate 2 through the rotating arm 3 in the running process of a vehicle so as to ensure the tightness in the vehicle.
In the running process of the vehicle, the air pressure tightens the door plate through the rotating arm to ensure the tightness in the vehicle, and in general, the air pressure of the passenger door is not large, so long as the normal opening or closing of the passenger door can be met, and the sealing requirement of the passenger door can be met. However, when the automobile runs at a high speed or encounters a bumpy road surface, a large difference is likely to occur between the dynamic deformation amount of the passenger door and the dynamic deformation amount of the automobile body, so that the rotating arm can not tighten the passenger door, the sealing performance of the passenger door is reduced, dust and air are further caused to enter the automobile, and finally, the automobile is subjected to dust entering or wind noise. However, if the passenger door pressure is increased to avoid the above-mentioned problems, the joint strip and the door frame are easily stuck too tightly to generate a large friction force when the passenger door is opened or closed, and the door panel cannot be lifted by the rotating arm, so that the passenger door cannot be opened or closed; in addition, passenger door internal components such as cylinders, valves and piping may be damaged by being subjected to too much pressure for a long period of time; further, excessive air pressure may cause noise (particularly door opening and exhaust noise) to be large when the passenger door is opened and closed.
Disclosure of Invention
The invention aims to provide a method for controlling closing force of a vehicle door, which solves the problem that the vehicle door cannot meet the sealing performance in the normal running process of the vehicle; the invention also aims to provide a vehicle for controlling the closing force of the door.
In order to achieve the above object, the present invention provides a method for controlling a door closing force, which comprises: a method for controlling the closing force of a vehicle door comprises the following steps of firstly, detecting the sealing state of the vehicle door; judging whether the sealing state of the vehicle door meets the set requirement or not; and step three, when the sealing state of the vehicle door is lower than the setting requirement, increasing the closing force of the vehicle door by increasing the closing driving force of the driving device so as to enable the sealing performance of the vehicle door to reach the setting requirement.
The method for controlling the closing force of the vehicle door has the beneficial effects that: the control method can detect the sealing state of the vehicle door and judge whether the sealing state of the vehicle door meets the set requirement, is very convenient, and can enable the sealing state of the vehicle door to meet the requirement by increasing the closing force of the vehicle door when the vehicle is not tightly sealed in the running process of the vehicle.
Further, defining the sealing state of the door is achieved by detecting a pressing force between the door and the door frame. The existing pressure sensor technology is mature, detection is convenient to achieve during application, and the sealing state of the vehicle door can be intuitively judged through the detected value.
Further, the limitation of the closing driving force of the increased driving means is achieved by adjusting a pressure adjusting valve of the driving means connected to the door. When the pressure regulating valve is opened, gas can enter a cylinder in the driving device to increase the gas pressure, so that the closing driving force of the driving device is increased.
Further, the steps one to three are defined to be executed only in the case where the vehicle speed is higher than the set value and/or in the case where the degree of vehicle jolt is greater than the set degree. When the vehicle speed is higher than a set value and/or the vehicle jolt degree is higher than the set degree, the dynamic deformation of the vehicle door is greatly different from the dynamic deformation of the vehicle body, so that the sealing performance of the vehicle door is easily poor, and the vehicle door Guan Geli is required to be added to meet the requirement of the sealing performance of the vehicle door.
Further, it is defined that in a case where the vehicle speed is lower than the set value and/or in a case where the degree of vehicle jerk is weaker than the set degree, the closing force of the door is reduced when the closing force of the door is higher than the set requirement. Too high a door closing force can make it very difficult to open and close the door while also damaging vehicle interior components, so that the door closing force is reduced when it is higher than the set requirement.
Further, when the vehicle speed is zero, the execution of the steps one to three is stopped. When the vehicle speed is zero, the vehicle stops running, and the execution of the first to third steps is required to be stopped.
The technical scheme of the vehicle for controlling the closing force of the vehicle door provided by the invention is as follows: the vehicle for controlling the door closing force comprises a vehicle body, a door, a driving device for driving the door to be closed, a detecting device for detecting the sealing state of the door, and a pressure regulating valve for increasing the closing driving force of the driving device, wherein the pressure regulating valve and the detecting device are connected with a control device.
Beneficial effects of the vehicle for controlling door closing force: the vehicle for controlling the closing force of the vehicle door can automatically adapt to the change of the pressing force between the vehicle door and the door frame when the tightness of the vehicle door is poor in the normal running process, and the driving force for driving the vehicle door to close is increased by the driving device through the control device so as to meet the requirement of the sealing performance of the vehicle door.
Further, in order to well detect the pressing force between the door and the door frame, a pressure sensor for detecting the pressing force between the door and the door frame is defined between the door and the door frame, and the detecting device comprises the pressure sensor.
Further, the pressure regulating valve is defined as an air inlet valve for controlling the on-off of an air inlet of the driving device and an air source. When the tightness of the vehicle door does not meet the requirement, namely the closing force of the vehicle door is smaller, the air source can enter the air cylinder in the driving device by opening the pressure regulating valve, and the closing force of the vehicle door is regulated by increasing the air pressure in the air cylinder.
Further, in order to ensure that the driving device cannot be pressurized infinitely, an air outlet of the driving device is connected with an air outlet valve, an air pressure sensor is arranged on the driving device, and the air outlet valve and the air pressure sensor are both connected with the control device. The air pressure sensor is arranged on the driving device and can detect the pressure of air in the driving device, when the tightness of the vehicle door does not meet the sealing requirement, and when the vehicle door cylinder is required to be pressurized, the air pressure sensor can well detect the pressure of the air in the cylinder, so that the vehicle door cannot be opened or closed due to overlarge air pressure of the air cylinder; when the pressure of the cylinder is overlarge in the running process of the vehicle, the control device controls the opening of the air outlet valve, and the air cylinder of the vehicle door is exhausted, so that the closing force of the vehicle door meets the requirement of tightness.

Embodiments of a control method of controlling a door closing force: the method comprises the following three steps that firstly, the sealing state of a vehicle door is detected, and the pressing force between the vehicle door and a door frame is detected through a pressure sensor 14; secondly, judging whether the sealing state of the vehicle door meets the set requirement, comparing the pressing force detected by the pressure sensor 14 with the pressing force between the vehicle door and the door frame when the vehicle door is opened or closed under normal conditions, and judging that the vehicle door does not meet the sealing requirement if the pressing force between the vehicle door and the door frame in the normal state is not met; and thirdly, when the sealing state of the vehicle door is lower than the set requirement, the closing force of the vehicle door is increased, and the pressure regulating valve of the driving device connected with the vehicle door is regulated. As shown in fig. 2, the driving device comprises an inflating pump 7, an air cylinder 10 and a rotating arm, wherein the pressure regulating valve is an air inlet valve 8, when the sealing state of the vehicle door is lower than the set requirement, the air inlet valve 8 is opened to enable the inflating pump 7 to inflate the air cylinder 10, and when the air pressure sensor 11 detects that the air pressure in the air cylinder 10 reaches the set air pressure (the air pressure capable of ensuring the tensioning of the vehicle door), the air inlet valve 8 is closed. These three steps are suitable for the vehicle to run at high speed and/or to run on bumpy road sections.
When the vehicle speed is lower than a set value and/or the degree of jerk of the vehicle is lower than a set degree, the closing force of the door is reduced when the closing force of the door is higher than a set requirement, and the air outlet valve 9 connected with the air cylinder 10 is opened to exhaust the air cylinder 10 until the air pressure sensor 11 detects that the air pressure in the air cylinder 10 reaches the set air pressure (the air pressure capable of ensuring the tensioning of the door).
And stopping the execution of the first step to the third step when the vehicle speed is zero.
The jolt degree of the vehicle is quantified by comparing the measured value of the pressing force detected by the pressure sensor 14 with the normal pressing force set value, and if the measured value of the pressing force detected by the pressure sensor 14 is changed drastically and is larger than the normal pressing force set value, the jolt degree of the vehicle is small; if the magnitude of the pressing force detected by the pressure sensor 14 is drastically changed and smaller than the normal pressing force set value, it is indicated that the degree of jolt of the vehicle is large.

As shown in fig. 2, the vehicle for controlling the closing force of the vehicle door further comprises a driving device for driving the vehicle door to close, wherein the driving device comprises an inflating pump 7, an air cylinder 10 and a rotating arm, the inflating pump 7 can inflate and punch the air cylinder 10, and a pressure regulating valve for controlling the on-off of the air cylinder 10 and the inflating pump 7, namely an air inlet valve 8, is arranged between the inflating pump 7 and the air cylinder 10 of the vehicle door. The cylinder 10 is provided with a gas pressure sensor 11 capable of detecting the pressure of the gas in the cylinder 10, and a gas outlet of the cylinder 10 is connected with a gas outlet valve 9. The vehicle is also provided with a signal processor 15 which is in control connection with the inflating pump 7, the air inlet valve 8 and the air outlet valve 9, the signal processor 15 is also connected with a vehicle speed sensor 13 and a pressure sensor 14, and in order to reduce the exhaust noise of the air cylinder 10, a pipeline muffler 16 is also arranged at the lower part of the air outlet valve 9.
When the vehicle runs, namely when the vehicle speed sensor 13 detects that the vehicle speed is greater than 0, the pressure sensor 14 starts to detect the pressing force between the door panel 12 and the door frame, when the pressing force value detected by the pressure sensor 14 is too small or is changed vigorously (bumpy road section) and is smaller than a normal pressing force set value, the signal processor 15 transmits a command to the air pump 7 and the air inlet valve 8, at the moment, the air inlet valve 8 is opened, the air pump 7 starts to work to pump and punch the air cylinder 10, when the air pressure sensor 11 detects that the air pressure in the air cylinder 10 reaches the expected air pressure, namely, the air pump 7 stops working when the air pressure in the air cylinder 10 can ensure the tensioning of the door, the air inlet valve 8 is closed, and at the moment, the door drives the door panel 12 to move upwards through the rotating arm so that the door is smoothly closed and tensioned, the door panel 12 is matched with the door frame in a sealing mode, dust and air are prevented from entering, and the sealing performance is ensured.
When the pressure sensor 14 detects that the pressing force value is too large or the pressing force value is severely changed (bumpy road section) and is larger than the normal pressing force set value in the running process of the vehicle, the signal processor 15 transmits a command to the position of the air outlet valve 9, the air outlet valve 9 starts to work to exhaust, the pipeline muffler 16 can help reduce exhaust noise, when the pressure sensor 11 detects that the pressure reaches the expected pressure, the vehicle door can be ensured to be smoothly opened, the air outlet valve 9 is closed, and the condition that the service life of parts in the vehicle is shortened due to the fact that the pressure of the door pump is too large for a long time is avoided; when the vehicle speed sensor 13 detects that the vehicle speed is 0, the system stops operating.
In the above embodiment, the detection of the sealing state of the door is achieved by the pressure sensor provided in the door panel of the door, and in other embodiments, the pressure sensor may be provided in the door frame of the door, so long as the pressing force between the door panel and the door frame can be detected, so that the tightness of the door can be detected; in other embodiments, the sealing state of the door may be detected by other means, for example, detecting the air pressure of the cylinder of the driving device to detect the tightness of the door, and detecting the degree of air noise at the door to detect the tightness of the door.
