Description

Technical Field

[0001] The present application relates to the field of sealing strips, and particularly to a door sealing system and an automobile thereof. Background Art

[0002] At present, the rear door / back door sealing strips used in automobiles on the market are made by rubber extrusion molding. The main reaction force of the sealing strip is determined by the cross-sectional shape of the rubber and the mechanical properties of the rubber material. After the sealing strip is installed, the sealing reaction force of the vehicle is basically determined, and only fine-tuning can be carried out through parts such as buffer blocks. Moreover, the adjustment time is long, workers need a long adjustment time, it is difficult to control the consistency of the adjustment, and it cannot adapt to the changes in the requirements for the sealing reaction force under various working conditions. For example, when opening and closing the door, a smaller sealing reaction force is required so that the door / back door can be closed more easily. When the vehicle starts and travels at a high speed, a higher sealing reaction force is required so that the door / back door can be stably fixed on the vehicle body to avoid the noise generated by the tremor of the door / back door.

[0029] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0030] The embodiments of this application provide a door sealing system and an automobile thereof, which can solve the problem that the sealing strip on the door in the related art cannot meet the requirements of the sealing reaction force under various working conditions.

[0031] In a first aspect, the embodiments of this application provide a door sealing system, which includes: a sealing strip unit, a sealing reaction force adjusting unit, a data acquisition unit 5, and a control unit 6. The sealing strip unit includes a sealing strip body 1 and a bubble tube assembly 2 arranged inside the sealing strip body 1. The bubble tube assembly 2 includes a liquid conduit 23. The sealing reaction force adjusting unit is connected to the liquid conduit 23 and is used to convey liquid into the liquid conduit 23. The data acquisition unit 5 is connected to the sealing reaction force adjusting unit and is used to acquire the liquid temperature. The control unit 6 is connected to the data acquisition unit 5 and the sealing reaction force adjusting unit. After the vehicle starts, the control unit 6 controls the sealing reaction force adjusting unit to convey liquid into the liquid conduit 23 according to the liquid temperature.

[0032] In this application, when the vehicle is stationary, the system does not work, and the sealing reaction force of the sealing strip unit mainly comes from the physical properties of the sealing strip unit. At this time, when opening and closing the door, due to the small sealing reaction force, it is easy to open and close the door. When the vehicle starts and travels, the temperature of the conveyed liquid is collected, and the sealing reaction force of the sealing strip unit is increased by conveying liquid into the sealing strip unit, which can stably fix the door on the vehicle body, improve the quietness and tremor of the vehicle during driving, overcome the problem that different working conditions have different requirements for the sealing reaction force, and enable the vehicle to have better driving quality.

[0033] In this application, heated liquid is conveyed into the liquid conduit 23, and the liquid located inside the sealing strip body 1 causes the sealing strip body 1 to heat and expand through the principle of "thermal expansion and contraction".

[0034] In this embodiment, the temperature of the liquid can be controlled so that the sealing strip body 1 has different degrees of expansion in different working conditions, further realizing the situation where different working conditions have different requirements for the sealing reaction force.

[0035] In other embodiments, the liquid temperature can also be set at a fixed value, and the sealing reaction force of the sealing strip unit can be compensated by cooperating with the method of conveying gas into the sealing strip body 1.

[0036] Specifically, in this embodiment, the bubble tube assembly 2 further includes a gas conduit 22, and the gas conduit 22 is connected to the seal reaction force adjustment unit. Therefore, the data acquisition unit 5 is further configured to acquire the internal air pressure value of the seal strip unit; after the vehicle is started, the control unit 6 is further configured to control the seal reaction force adjustment unit to deliver gas into the gas conduit 22 according to the internal air pressure value of the seal strip unit.

[0037] In this embodiment, the gas conduit 22 is provided with a relatively large elasticity, so that when the seal reaction force adjustment unit inputs gas into the gas conduit 22, the gas conduit 22 can be inflated, thereby increasing the seal reaction force of the seal strip unit.

[0038] In order to reduce costs, instead of re-setting a new liquid heating and conveying device, in this embodiment, the engine 3 coolant is conveyed into the liquid conduit 23.

[0039] Therefore, the seal reaction force adjustment unit is provided to include: an engine 3 and an inflation assembly 4. The liquid conduit 23 is connected to the coolant pipeline on the engine 3, and the engine 3 conveys coolant into the liquid conduit 23 through the coolant pipeline; after the vehicle is locked and started, the data acquisition unit 5 continuously acquires the engine 3 coolant temperature and feeds it back to the control unit 6; after the vehicle is started, and when the liquid temperature is greater than or equal to the temperature set value, the control unit 6 controls the seal reaction force adjustment unit to convey liquid into the liquid conduit 23, that is, the control unit 6 will allow the seal strip unit to start the coolant circulation to heat the seal strip body 1, and the high-temperature coolant will circulate through the liquid conduit 23 to heat the air around the coolant.

[0040] Among them, the data acquisition unit 5 includes a temperature sensor, and the temperature sensor is used to acquire and send the liquid temperature, that is, the coolant temperature; the control unit 6 includes a first controller 60, and the first controller 60 is connected to the seal reaction force adjustment unit and the temperature sensor, and controls the seal reaction force adjustment unit to convey liquid into the liquid conduit 23.

[0041] The inflation assembly 4 is connected to the gas conduit 22, and the inflation assembly 4 conveys gas into the gas conduit 22; the data acquisition unit 5 continuously acquires the internal air pressure value of the seal strip body 1. When the coolant temperature is constant, if the seal reaction force of the seal strip unit is insufficient, the control unit 6 issues an inflation command to the inflation assembly 4 to supplement gas into the seal strip body 1, which can enable the seal strip unit to obtain a relatively large seal reaction force; at this time, it can ensure that the gas inside the bubble tube is stable at a certain temperature, thereby maintaining stable pressure, and the data acquisition unit 5 synchronously feeds back the internal air pressure value of the seal strip body 1 to the control unit 6 to ensure that the seal reaction force during driving is stable to the required sealing force and maintain the stability of the system force.

[0042] Further, the inflation assembly 4 includes: an air storage cylinder 40 and a compressor 41. One end of the compressor 41 is connected to the air storage cylinder 40, and the other end is connected to one end of the gas conduit 22. Wherein, the other end of the gas conduit 22 is connected to the air storage cylinder 40.

[0043] Specifically, if the sealing reaction force of the seal strip unit is insufficient, the control unit 6 issues an inflation command to the inflation assembly 4. After receiving the command, the compressor 41 pumps air from the air storage cylinder 40 into the gas conduit 22, allowing compressed air to enter the inside of the seal strip body 1 to complete the increase of the sealing reaction force.

[0044] When deflating, the control unit 6 issues an instruction, and the gas conduit 22 deflates, reducing the air pressure inside the seal strip unit. The air pressure flows back into the air storage cylinder 40, completing the deflation operation. At this time, the process of reducing the sealing reaction force of the seal strip is completed.

[0045] Further, the inflation assembly 4 further includes: an air valve 42. The air valve 42 is provided with a first valve 420, a second valve 421, and a third valve 422. The compressor 41 is connected to the air valve 42 through the first valve 420. One end of the air storage cylinder 40 is connected to the compressor 41, and the other end is connected to the air valve 42 through the second valve 421. The gas conduit 22 is connected to the air valve 42 through the third valve 422.

[0046] Therefore, if the sealing reaction force of the seal strip unit is insufficient, the control unit 6 issues an inflation command to the inflation assembly 4. After receiving the command, the compressor 41 pumps air from the air storage cylinder 40 into the gas conduit 22, passing through an air valve 42 in the middle, allowing compressed air to enter the seal strip unit.

[0047] Wherein, the data acquisition unit 5 further includes a pressure sensor 50 for collecting and transmitting the air pressure value of the seal strip body 1. The control unit 6 further includes a second controller 61, which is connected to the sealing reaction force adjustment unit and the pressure sensor 50, and controls the sealing reaction force adjustment unit to deliver liquid into the liquid conduit 23.

[0048] A pressure sensor 50 is provided inside the air valve 42, which feeds back the air pressure signal of the seal strip unit to the control unit 6. After receiving the signal, the second controller 61 issues an instruction to stop the compressor 41, and at the same time, all the valve channels of the air valve 42 are closed. At this time, the process of increasing the sealing reaction force is completed.

[0049] When deflating, after the control unit 6 issues an instruction, the valve of the air valve 42 gradually opens, the air pressure inside the seal strip decreases, and the air pressure flows back into the air storage cylinder 40. According to the air pressure condition in the air valve 42, the pressure sensor 50 feeds back the signal to the second controller 61. At this time, the second controller 61 issues an instruction to close the valve of the air valve 42, completing the deflation operation. At this time, the process of reducing the sealing reaction force of the seal strip is completed.

[0050] Specifically, the structural diagram of the air valve 42 is shown in Figure 4 . A pressure sensor 50 is provided in the air valve 42, and a first valve 420, a second valve 421 and a third valve 422 are also provided. The first valve 420 is connected to the compressor 41, the second valve 421 is connected to the air storage tank 40, and the third valve 422 is connected to the gas conduit 22.

[0051] During inflation, the compressor 41 starts to work. At this time, the second valve 421 is closed, the first valve 420 and the third valve 422 are opened, and inflation begins into the gas conduit 22. The pressure value in the sealing strip body 1 is identified by the pressure sensor 50. After the pressure value reaches the target requirement, the second controller 61 issues an instruction to stop the compressor 41, and the first valve 420 and the third valve 422 are closed, and the inflation process ends. During deflation, the first valve 420 is closed, the third valve 422 is opened first, and then the second valve 421 is opened. The pressure sensor 50 identifies the pressure value in the sealing strip body 1. After the pressure reaches the target requirement, the second controller 61 issues an instruction to close the second valve 421 and the third valve 422, and the deflation process ends.

[0052] Taking the cooperation of the gas conduit 22 and the liquid conduit 23 to adjust the sealing reaction force of the sealing strip unit as a preferred embodiment for description:

[0053] Among them, the bubble tube assembly 2 further includes: a first bubble tube 20 and a second bubble tube 21. The first bubble tube 20 is arranged inside the sealing strip body 1; the second bubble tube 21 is arranged inside the sealing strip body 1, and the liquid conduit 23 penetrates through the inside of the second bubble tube 21, and the gas conduit 22 is located inside the second bubble tube 21.

[0054] The sealing strip body 1 is an adaptive sealing strip. When the rubber bubble tube is co-extruded and formed, a section of gas conduit 22 and liquid conduit 23 are extruded. The gas conduit 22 is connected to the inflation assembly 4 through a conduit, and gas can be filled or released in the gas conduit 22. The liquid conduit 23 is connected to the vehicle coolant, and the sealing reaction force can be dynamically adjusted according to the vehicle state.

[0055] Based on the above embodiments, in this embodiment, the gas conduit 22 and the liquid conduit 23 have different setting methods:

[0056] In some possible embodiments, the inner wall of the gas conduit 22 is attached to the outer peripheral surface of the liquid conduit 23. In this embodiment, it can be set that the liquid conduit 23 penetrates through the inside of the gas conduit 22 as shown in Figure 2 . It can also be set that a plurality of gas conduits 22 are circumferentially and spacedly attached to the outer peripheral surface of the liquid conduit 23. The high-temperature coolant in the liquid conduit 23 can heat the gas conduit 22 and the sealing strip body 1, so that the gas conduit 22 and the sealing strip body 1 expand by heating.

[0057] In some other possible embodiments, the inner wall of the liquid conduit 23 fits against the outer peripheral surface of the gas conduit 22. In this embodiment, it can be arranged that the gas conduit 22 passes through the inside of the liquid conduit 23. In addition, a plurality of liquid conduits 23 can be circumferentially and spacedly attached to the outer peripheral surface of the gas conduit 22. The high-temperature coolant in the liquid conduit 23 can heat the gas conduit 22 and the seal strip body 1, causing the gas conduit 22 and the seal strip body 1 to expand due to heating.

[0058] The above embodiments are only various possible implementation manners of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0059] On the basis of the above embodiments, in this embodiment, after the vehicle is started, the control unit 6 controls the seal reaction force adjustment unit to deliver a gas with a target delivery volume into the gas conduit 22 based on the vehicle driving mode and the corresponding relationship between the vehicle driving mode and the gas delivery volume.

[0060] When the vehicle is stationary, at this time, the air pressure value in the seal strip body 1 is the initial value, and the sealing reaction force of the door body (door and rear door) is supported by the contact between the first bubble tube 20 and the seal strip body 1 and the sheet metal. The sealing reaction force of the first bubble tube 20 is mainly set by the physical properties of the rubber part and the compression amount of the elastic rubber part. At this time, when opening and closing the door, since the sealing reaction force is small, it is easy to open and close the door. When the vehicle starts and runs, according to the selected driving mode of the vehicle, the air pressure value in the gas conduit 22 is dynamically adjusted, so that a certain amount of air pressure is filled in the gas conduit 22, and the sealing reaction force signal is fed back to the second controller 61, thereby avoiding problems such as abnormal noises in the door and rear door under various working conditions. Since the gas pressure generated by the same volume of gas is inconsistent when the vehicle is running in different temperature ranges, there may be a change in gas pressure, and at this time, some compensation is also required to stabilize the gas pressure. It should be noted that in the present application, the set driving modes include a normal mode, a sports mode, and a mountain mode. In other embodiments, the driving mode can also be adaptively adjusted according to the actual situation.

[0061] In summary, in the present application, the control of the sealing unit mainly has two purposes: to provide an initial sealing reaction force, making the initial sealing reaction force relatively small and facilitating the easy closing of the door / rear door; to enable the sealing reaction force to change according to the road conditions and driving mode, providing an appropriate sealing reaction force so as to stably fix the door / rear door on the vehicle body and avoid large-amplitude tremors.

[0062] This application adjusts and maintains the sealing reaction force of the sealing unit by combining the high-temperature coolant circulation and inflation method of the engine 3, overcomes the change in the sealing reaction force caused by the change in the environmental temperature during the inflation of the sealing strip, enables the gas filled inside the sealing strip to maintain a stable pressure state, improves the vehicle quietness and tremor during driving, and can adjust the gas pressure according to the road conditions as required, and then adjust to the sealing reaction force required by the vehicle and stably maintain it, overcoming the influence of the environmental temperature on the sealing reaction force during driving, so that the vehicle has better driving quality.

[0063] In a second aspect, an embodiment of this application provides an automobile, which includes: the door body sealing system provided in any of the above embodiments of this application.

[0064] In this application, when the vehicle is stationary, the system does not work, and the sealing reaction force of the sealing strip unit mainly comes from the physical properties of the sealing strip unit. At this time, when opening and closing the door body, due to the small sealing reaction force, it is easy to open and close the door body; when the vehicle starts to drive, the temperature of the transported liquid is collected, and the sealing reaction force of the sealing strip unit is increased by transporting the liquid into the sealing strip unit, which can stably fix the door body on the vehicle body, improve the vehicle quietness and tremor during driving, overcome the problem of different requirements for the sealing reaction force under different working conditions, and make the vehicle have better driving quality.
