Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

The utility model provides a door sealing device, is including setting up the sealing strip 3 that matches between automobile body main part 1 and door main part 2, as shown in figure 1, has cavity 31 in the sealing strip 3 among the prior art, conveniently fills the space through the deformation between automobile body main part 1 and door main part 2 to play the effect of sealed door.

In the present embodiment, an elastic pressure increasing pipe 32 is arranged in the cavity 31 and has a size matching with the cavity 31 in the sealing strip 3, as shown in fig. 2, wherein the elastic pressure increasing pipe 32 is connected with a pressure increasing device capable of inflating the elastic pressure increasing pipe 32 and a pressure relieving device for relieving the pressure in the elastic pressure increasing pipe 32.

At normal conditions, such as when the vehicle is stationary or the doors are open, the elastic pressure-increasing duct 32 of the weather strip 3 is at an initial pressure value; when the vehicle is started or in a driving state, the vehicle door is in a state or environment where the sealing effect needs to be improved, at this time, the elastic pressure increasing pipe 32 in the sealing strip 3 can be inflated through the pressure increasing device, so that the sealing strip 3 achieves a preset sealing effect through the expansion of the internal elastic pressure increasing pipe 32, as shown in fig. 3.

When the working state of the vehicle changes or the door does not need to achieve the previous preset sealing effect, the air pressure in the elastic pressurization pipe 32 can be discharged through the pressure relief device, so that the elastic pressurization pipe returns to the initial state.

In the above-described door sealing device, only one elastic pressure increasing tube 32 is not provided in the weather strip 3, and in consideration of the possibility of damage to the elastic pressure increasing tube 32, the number of the elastic pressure increasing tubes 32 may be increased to 2 to 3, may be arranged in parallel, or may be arranged in a vertical section. When in use, the elastic pressure increasing pipes 32 can be simultaneously inflated and pressurized, and even if one of the elastic pressure increasing pipes 32 is damaged, the other elastic pressure increasing pipe 32 can be pressurized, so that the sealing effect of the vehicle door is ensured.

For the pressurization device, in this embodiment, the air compressor 4 is used to directly pressurize the elastic pressurization pipe 32, or at least one pressure tank may be disposed between the air compressor 4 and the elastic pressurization pipe 32 to store high-pressure gas, and the pressure tank may charge the high-pressure gas into the elastic pressurization pipe 32 to expand the high-pressure gas. The pressure relief device may employ a common pressure relief valve 8.

In order to apply the above-described door sealing device to a vehicle, the present embodiment provides a door sealing control system, which, as shown in fig. 4 and 5, includes, in addition to the above-described door sealing device, a first sensing unit 11 for detecting a closed state of a door, and a control unit 5, and the control unit 5 is electrically connected to the first sensing unit 11 and the pressure increasing device, respectively.

When the first sensing unit 11 detects that the vehicle door is in a closed state, the control unit 5 controls the pressurizing device to inflate the elastic pressurizing pipe 32 to a first preset pressure value.

In another embodiment, the door seal control system further comprises a second sensing unit 12 for detecting whether the vehicle is flooded, as shown in fig. 6. When the first sensing unit 11 detects that the vehicle door is in a closed state, if the second sensing unit 12 also detects that the vehicle is in a submerged state (for example, raining, passing through a catchment area, or falling into a river), the control unit 5 controls the pressurizing device to inflate the elastic pressurizing pipe 32 to a second preset pressure value. Because the condition is higher than the requirement of closing and sealing the common vehicle door, the second preset pressure value is obviously higher than the first preset pressure value, at the moment, the elastic pressure pipe 32 is continuously inflated by the pressurizing device to reach the second preset pressure value, and the sealing effect of the vehicle door is further improved, so that the vehicle and passengers are protected.

It should be noted that when the second sensing unit 12 detects that the vehicle is out of the water-immersed state, the control unit 5 may control the pressure relief device to exhaust the excess air pressure in the elastic pressure increasing tube 32 to reach the first preset pressure value, so as to facilitate the opening of the vehicle door by the occupant.

As shown in fig. 7, in the present embodiment, the door seal control system further includes a third sensing unit 13 for detecting the running vehicle speed of the automobile. When the first sensing unit 11 detects that the vehicle door is in a closed state, if the third sensing unit 13 detects that the vehicle is in a high-speed mode, that is, the vehicle speed reaches a set speed threshold, the control unit 5 controls the pressurization device to inflate the elastic pressurization pipe 32 to a third preset pressure value. Because the sealing requirement of the situation is higher than that of the common vehicle door closing or low-speed running, the third preset pressure value is obviously greater than the first preset pressure value, and at this time, the control unit 5 controls the pressurizing device to continuously inflate the elastic pressurizing pipe 32 to reach the third preset pressure value, so that the sealing effect of the vehicle door is ensured.

It should be noted that when the third sensing unit 13 detects that the vehicle is not in a high-speed driving state, the control unit 5 may control the pressure relief device to discharge the excess air pressure in the elastic pressure increasing tube 32 to a first preset pressure value. The speed threshold for high speed driving is not a specific value, because there is a variation of the vehicle around the speed value, which may cause the pressure boosting device and the pressure relief device to start operating on the contrary, therefore, the speed threshold is preferably selected from a range, such as 80-100 km/h, when the speed of the vehicle is lower than 80 km/h, the air pressure in the elastic pressure boosting tube 32 is controlled at the first preset pressure value, when the vehicle accelerates to 80-100 km/h, if the duration of the vehicle in the speed range is not enough, the air pressure in the elastic pressure boosting tube 32 is still maintained at the first preset pressure value, and if the duration of the vehicle in the speed range exceeds the range or the speed of the vehicle exceeds 100 km/h, the control unit 5 controls the pressure boosting device to continue to inflate the elastic pressure boosting tube 32 to the third preset pressure value. When the vehicle decelerates from 100 km/h or above, if the vehicle decelerates to 80-100 km/h, the air pressure in the elastic booster tube 32 still maintains at the third preset pressure value, and when the vehicle decelerates continuously to 80 km/h or below, the control unit 5 controls the pressure relief device to discharge the redundant air pressure in the elastic booster tube 32 to make it reach the first preset pressure value.

When the vehicle has decelerated to a speed of less than 80 km/h and if the vehicle has accelerated to a speed of more than 80 km/h shortly, control unit 5 may adjust the air pressure inside flexible pressure inlet tube 32 in accordance with the control mode used when the vehicle is accelerated.

In order to fully utilize the high-pressure gas, the embodiment provides another vehicle door sealing control system, as shown in fig. 8, in order to use the high-pressure gas generated by the pressurization device for cleaning the vehicle (which can clean the engine compartment or other parts which cannot be cleaned by water), a quick connector 9 can be additionally arranged for installing a high-pressure gas gun, a reversing valve 7 connected with the control unit 5 is arranged between the pressurization device and the pressure relief device, and the reversing valve 7 is used for controlling whether the gas generated by the pressurization device flows into the elastic pressurization pipe 32 or flows into the quick connector 9.

When the supercharging device normally inflates the elastic supercharging pipe 32, the control unit 5 adjusts the reversing valve 7, so that high-pressure gas generated by the supercharging device is conveyed to the elastic supercharging pipe 32, and the sealing effect of the vehicle door is improved.

When the high-pressure gas generated by the supercharging device is required to be used for cleaning, the reversing valve 7 is adjusted through the control unit 5, so that the high-pressure gas generated by the supercharging device is conveyed to the direction of the quick connector 9, the quick connector 9 can clean the automobile by installing a high-pressure air gun, and the high-pressure gas can be used for sealing and cleaning the automobile door and inflating tires.

In addition to cleaning the vehicle with high-pressure gas, the vehicle may also be cleaned with high-pressure water, as shown in fig. 9, the vehicle door sealing control system in this embodiment is added with a water pump 6, and the control unit 5 provides a water source to the pressure boosting device by controlling the water pump 6, specifically, the water pump 6 pumps the water source into the pressure tank of the pressure boosting device, so as to form high-pressure water. When high-pressure water cleaning is selected, the reversing valve 7 only allows the pressure tank to be communicated with the quick connector 9.

The input end of the water pump 6 can be externally connected with a water tap as a water source.

When high-pressure water cleaning is needed, firstly, the control unit 5 controls the water pump 6 to pump a water source into the pressure tank, meanwhile, the reversing valve 7 is controlled to enable high-pressure water generated by the supercharging device to flow to the quick connector 9, and the quick connector 9 cleans an automobile by installing a high-pressure water gun, so that the cleanness of the automobile is kept.

Considering that the pressure tanks can contain limited high-pressure water, a plurality of pressure tanks can be arranged in parallel, so that the high-pressure water gun can be alternately used, and stable high-pressure water can be always ensured. As shown in fig. 9, in the present embodiment, a pressure tank G1 and a pressure tank G2 are provided, wherein a water inlet of the pressure tank G1 is provided with a water inlet electromagnetic valve A4, a gas inlet is provided with a gas inlet electromagnetic valve A3, a water inlet of the pressure tank G2 is provided with a water inlet electromagnetic valve A1, and a gas inlet is provided with a gas inlet electromagnetic valve A2. The water inlet electromagnetic valves A1 and A4 and the air inlet electromagnetic valves A2 and A3 are controlled by a control unit 5.

The control process of the door seal control subsystem in this embodiment by the control unit 5 is as follows:

(1) Door seal mode: closing the water inlet electromagnetic valves A1 and A4, opening at least one of the air inlet electromagnetic valves A2 and A3, then starting the air compressor 4 to inflate the air pressure tank, so as to generate high-pressure air, adjusting the reversing valve 7 to enable the high-pressure air generated by the pressure tank to be conveyed to the direction of the elastic pressure increasing pipe 32, and sealing the vehicle door.

(2) High pressure air cleaning or tire inflation mode: the water inlet electromagnetic valves A1 and A4 are closed, at least one of the air inlet electromagnetic valves A2 and A3 is opened, the reversing valve 7 is adjusted to enable high-pressure gas generated by the pressure tank to be conveyed to the direction of the quick connector 9, and the automobile can be cleaned and tires can be inflated by installing and installing a high-pressure air gun.

(3) High-pressure water cleaning mode: closing the air inlet electromagnetic valves A2 and A3, adjusting the reversing valve 7 to enable high-pressure water generated by the pressure tank to be conveyed to the direction of the quick connector 9, opening the water inlet electromagnetic valve A4, starting the water pump 6 to inject water into the pressure tank G1, after a certain amount of water is accumulated in the pressure tank G1, closing the water inlet electromagnetic valve A4 and simultaneously opening the air inlet electromagnetic valve A3, immediately starting the air compressor 4, enabling high-pressure gas to enter the pressure tank G1 through the electromagnetic valve A3, and enabling the high-pressure gas to be sprayed out of the quick connector 9 through the reversing valve 7 in a high-pressure mode; when the water inlet electromagnetic valve A4 is closed, the water inlet electromagnetic valve A1 is opened, water is injected into the pressure tank G2, after a certain amount of water is accumulated in the pressure tank G2, the air inlet electromagnetic valve A3 is closed, the air inlet electromagnetic valve A2 is opened, and high-pressure gas enters the pressure tank G2 through the electromagnetic valve A2 and is sprayed out of the quick connector 9 through the reversing valve 7 in a high-pressure mode. The air inlet electromagnetic valve A3 is closed, the water inlet electromagnetic valve A4 is opened, water is injected into the pressure tank G1 again, and the water in the pressure tanks G1 and G2 is sprayed out from the quick connector 9 through the reversing valve 7 in a high-pressure mode in a circulating reciprocating mode, so that the cleaning work of high-pressure water is realized.

Because the pressure tank G1 and the pressure tank G2 have the same function, the control process can also realize that water in the pressure tank G1 and the pressure tank G2 circulates and is sprayed out from the quick connector 9 in a high-pressure mode by injecting water into the pressure tank G2 and then injecting water into the pressure tank G1.

The control unit 5 may be provided with a control button interface for selecting the system operation mode, which in addition to the automatic control system for the door sealing, should include a high pressure air cleaning or tire inflation mode and a high pressure water cleaning mode, which can be manually selected.

Generally speaking, the power supply in the automobile is started by a storage battery when the automobile is started, and the power supply is carried out by a generator after the automobile is started, but when the automobile is soaked in water, the storage battery can not be used, and at the moment, an independent waterproof storage battery 10 can be matched with the control system to supply power, so that the power supply of the sealing control system is provided when the automobile is soaked in water, and the normal work of the sealing control system of the automobile door is ensured.
