Description

Technical Field

[0001] This application relates to the field of vehicle sealing technology, and more specifically, to a vehicle sealing system. Background Technology

[0002] Vehicle sealing strips are important components installed on the car body, windows, sunroof, trunk, etc., to provide sealing, sound insulation, dustproofing, waterproofing and cushioning functions; in order to ensure the vehicle's drainage performance, several drainage holes are usually set on the bottom inside of the door to facilitate the drainage of small amounts of water that seep into the door cavity.

[0003] In existing technology, a sealing strip is also installed at the bottom of the vehicle body. When the door is closed, the bottom of the door comes into close contact with the sealing strip, preventing water flowing from the drainage holes from draining properly. In damp or rainy weather, if water flowing into the door cavity cannot drain properly, it can lead to corrosion of the door's metal inner panel, malfunction of electrical components, or unpleasant odors. To avoid these problems, some vehicles are designed without the sealing strip at the bottom of the door to ensure drainage, but this significantly reduces dustproofing and sound insulation. Therefore, existing technologies cannot simultaneously achieve both sealing and drainage effectiveness. Summary of the Invention

[0006] Furthermore, the vehicle sealing system also includes: a first sensor disposed in the inner cavity, the first sensor being used to detect the moisture content in the inner cavity; a drive unit, the drive unit being used to drive the sealing strip to switch between a sealing state and a drainage state; and a controller, the controller being electrically connected to both the drive unit and the first sensor, the controller controlling the operation of the drive unit based on the detection data from the first sensor.

[0007] Furthermore, the driving component includes an air pump, the sealing strip has a chamber, the air pump is connected to the chamber via a pipeline, and the air pump switches between a sealing state and a drainage state by changing the volume of the sealing strip.

[0008] Furthermore, the vehicle sealing system also includes a control valve, which is installed on the pipeline connecting the air pump and the sealing strip, and the controller is electrically connected to the control valve.

[0009] Furthermore, the sealing strip includes a base and an airbag. The base is fixed to the outer panel of the side skirt, and the base extends in the same direction as the outer panel of the side skirt. The airbag has an opening and a chamber, and the airbag is connected to the base through the opening.

[0010] Furthermore, the vehicle sealing system also includes a second sensor, which is mounted on the vehicle body. The second sensor is used to detect the amount of rainfall and is electrically connected to the controller. The controller controls the operation of the drive components based on the data from the first and second sensors.

[0015] By applying the technical solution of this application embodiment, the sealing strip is configured with both a sealing state and a drainage state. When drainage is required, the sealing strip is switched to the drainage state and the gap is opened, allowing water flowing out of the drainage hole to drain smoothly, preventing water accumulation in the inner cavity from causing metal corrosion and damage to electronic components. When drainage is not required, the sealing strip is switched to the sealing state, achieving the effects of sealing, sound insulation, and dust prevention.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] like Figures 1 to 4 As shown, an embodiment of this application provides a vehicle sealing system, which includes a vehicle body 10, a door 20, and a sealing strip 30. The vehicle body 10 has a side skirt outer panel 11 for mounting the sealing strip 30. The door 20 is movably connected to the vehicle body 10, with a gap 12 between the bottom edge of the door 20 and the side skirt outer panel 11. The door 20 has an inner cavity 20a and a drain hole 20b, which communicate with each other. The inner cavity 20a provides a flow path for water accumulating inside and outside the door 20, while the drain hole 20b is located on the inner sidewall of the door 20 at its bottom and is used to drain water flowing into the inner cavity 20a. A sealing strip 30 is provided on the outer panel 11 of the side skirt. The sealing strip 30 is lower than the drain hole 20b in the height direction. The sealing strip 30 has a sealing state and a draining state that are arranged opposite to each other. When the sealing strip 30 is in the sealing state, the sealing strip 30 seals the gap 12. When the sealing strip 30 is in the draining state, the sealing strip 30 opens the gap 12. Figure 1 The direction indicated by the X-axis is the length direction of the vehicle body 10.

[0041] By applying the technical solution of this application, the sealing strip 30 is configured to have both a sealing state and a drainage state. When drainage is required, the sealing strip 30 is switched to the drainage state and the gap 12 is opened, allowing water flowing out of the drainage hole to drain smoothly and preventing water from accumulating in the inner cavity 20a, which could cause metal corrosion and damage to electronic components. When drainage is not required, the sealing strip 30 is switched to the sealing state to achieve the effects of sealing, sound insulation, and dust prevention. The vehicle sealing system provided by this application achieves a balance between sealing and drainage effects, satisfying the dual needs of daily dust prevention and sound insulation as well as drainage in rainy weather.

[0042] In this embodiment, the inner cavity 20a, the drain hole 20b, and the gap 12 work together to guide the water accumulated inside the door 20 to drain smoothly out of the vehicle. Specifically, when water flows into the inner cavity 20a, it flows downward along the side wall of the inner cavity 20a under the influence of gravity. Since the inner cavity 20a is connected to the drain hole 20b, the water flows to the drain hole 20b, and then flows into the gap 12 and drains out of the vehicle. During the above process, the sealing strip 30 is in a draining state, opening the gap 12 to facilitate the drainage of water out of the vehicle. When there is no water, the sealing strip 30 is in a sealing state, sealing the gap 12.

[0043] Specifically, the sealing strip 30 can open or seal the gap 12 by moving it. In other embodiments, the gap 12 can also be opened or sealed by changing the volume of the sealing strip 30. By opening or sealing the gap 12 with the sealing strip 30, the sealing state and the drainage state can be switched between each other, which improves the flexibility of the sealing strip 30. This ensures that the sealing strip 30 can effectively seal to prevent external pollutants from entering, and can also quickly drain water when necessary, avoiding damage such as corrosion of the door 20 and damage to electronic components caused by internal water accumulation, thereby improving the overall durability of the vehicle and the user experience.

[0044] In a specific embodiment of this application, the vehicle sealing system further includes a first sensor 41, a drive unit 42, and a controller 43. The first sensor 41 is disposed in the inner cavity 20a and can detect the moisture content in the inner cavity 20a. The drive unit 42 is used to drive the sealing strip 30 to switch between a sealing state and a drainage state. The controller 43 is electrically connected to both the drive unit 42 and the first sensor 41, and controls the operation of the drive unit 42 based on the detection data of the first sensor 41, so that the drive unit 42 moves quickly to switch the different states of the sealing strip 30.

[0045] In use, when the first sensor 41 detects that the water content in the inner cavity 20a exceeds or falls below a preset value, the controller 43 acquires the detection data from the first sensor 41. Based on the detection data, the controller 43 controls the drive component 42 to operate, causing the sealing strip 30 to switch between a sealing state and a drainage state. In a specific embodiment of this application, the first sensor 41 is positioned near the drain hole 20b in the inner cavity 20a to more accurately detect the water content inside the door, preventing excessive water accumulation from affecting the electrical components inside the door.

[0046] In a specific embodiment of this application, the first sensor 41 is a humidity sensor, which detects humidity to reflect the water content in the inner cavity 20a. The humidity detection threshold of the inner cavity 20a preset by the first sensor 41 is between 60% and 80%, which can be specifically set according to environmental factors such as the region and climate where the vehicle is located.

[0047] The above settings enable more precise detection of the moisture content within the inner cavity 20a, especially near the drain hole 20b, without manual intervention, achieving intelligent sealing and drainage management. Furthermore, humidity detection thresholds tailored to different regions or climates can be set, allowing for more accurate determination of whether the vehicle needs drainage. This effectively balances sealing and drainage requirements, improving the vehicle's flexibility and adaptability when switching between sealed and draining states.

[0048] In a specific embodiment of this application, the drive component 42 includes an air pump, and the sealing strip 30 has a chamber. The air pump is connected to the chamber via a pipe 44. The air pump switches between a sealing state and a drainage state by changing the volume of the sealing strip 30. Specifically, the controller 43 controls the air pump to pump or evacuate air from the sealing strip 30. When drainage is required, the air pump draws gas from the chamber of the sealing strip 30 through the pipe 44, creating a negative pressure inside, thereby deforming and opening the gap 12, forming a drainage channel between the inner cavity 20a, the drainage hole 20b, and the gap 12, ensuring that accumulated water can be quickly discharged. When drainage is not required for daily use, the air pump fills the chamber of the sealing strip 30 with gas through the pipe 44, causing the sealing strip 30 to seal the gap 12, restoring its original sealing state, preventing dust, noise, etc., from entering the vehicle interior, and ensuring vehicle comfort.

[0049] In one specific embodiment of this application, a miniature air pump is selected. On the one hand, it can meet the performance requirements of the expansion and contraction of the sealing strip 30. On the other hand, it can save interior space of the vehicle, avoid excessive interference between various components, and facilitate maintenance.

[0050] In a specific embodiment of this application, the vehicle sealing system further includes a control valve, which is installed on the pipeline 44 connecting the air pump and the sealing strip 30. The controller 43 is electrically connected to the control valve. During use, when the air pump draws gas from the chamber or delivers gas to the chamber, once the chamber reaches a predetermined pressure, the controller 43 controls the control valve to cut off the connection between the air pump and the chamber via the pipeline 44 and stop the air pump from operating. The control valve maintains the gas pressure within the sealing strip 30, thus preventing the air pump from continuously operating, thereby avoiding energy waste and damage to the air pump due to overpressure, and ensuring that the gas pressure within the chamber is within a suitable range.

[0051] A pressure sensor can be installed in the chamber to detect the air pressure inside the chamber. When the pressure sensor reaches the preset air pressure value, it transmits the pressure signal to the controller 43. The controller 43 controls the control valve to cut off the connection between the air pump and the chamber pipeline 44 and stop the air pump from working.

[0052] like Figure 3As shown, the sealing strip 30 includes a base 31 and an airbag 32. The base 31 is fixed to the outer side skirt panel 11, and the extension direction of the base 31 is the same as that of the outer side skirt panel 11, ensuring the precise positioning and stable installation of the sealing strip 30 on the vehicle body 10. The airbag 32 has an opening, and a chamber is formed inside the airbag 32. The airbag 32 is connected to the base 31 through the opening.

[0053] In some embodiments of this application, the base 31 is fixed to the outer side skirt plate 11 by adhesive or snap-fit, which facilitates installation and also provides good connection performance.

[0054] In one specific embodiment of this application, the side profile of the airbag 32 is "C" shaped. When sealed, the outer surface of the airbag 32 can fit well with the bottom of the door 20 to achieve a good sealing effect. In addition, the opening of the airbag 32 is fixedly connected to the base 31 by adhesive bonding, so that the opening fits tightly with the base 31 to ensure good airtightness of the chamber.

[0055] In other embodiments, a reinforcing strip can be glued to the connection between the opening and the base 31. The reinforcing strip extends in the same direction as the base 31 and the side skirt outer plate 11, further reinforcing the connection between the opening and the base 31 and ensuring the stability and durability of the connection.

[0056] To improve the detection effect, the vehicle sealing system also includes a second sensor, which is installed on the vehicle body 10. The second sensor can detect the amount of rain. The second sensor is electrically connected to the controller 43. The controller 43 can control the operation of the drive component 42 based on the detection data of the first sensor 41 and the second sensor, so that the controller 43 can integrate the data of the first sensor 41 and the second sensor and accurately control the operation of the drive component 42.

[0057] In practical use, when either the first sensor 41 or the second sensor reaches a preset value, the controller 43 controls the drive unit 42 to work. Alternatively, the controller 43 can control the drive unit 42 to work when both the first sensor 41 and the second sensor reach the preset value.

[0058] In other embodiments of this application, the second sensor transmits detection data to the controller 43 based on the amount of rainfall. The controller 43 adjusts the detection threshold set by the first sensor 41 according to the detection data from the second sensor, thereby adapting to the surge in humidity in the air during rainy weather. This prevents the sealing strip 30 from entering a drainage state and opening the gap 12 when there is no water accumulation in the inner cavity 20a but the humidity is high, which could cause rainwater to seep back into the inner cavity 20a from the gap 12. Furthermore, when the rain stops and the humidity drops to a suitable range, the system can promptly return to the sealing mode, ensuring that the vehicle's dustproof and sound insulation performance is not affected, and improving the flexibility of the vehicle's sealing system.

[0059] In this embodiment, there are multiple drainage holes 20b, which are spaced apart along the length of the vehicle body 10 on the door 20. Specifically, the drainage holes 20b can be arranged according to the locations in the inner cavity 20a where water easily accumulates, so that the accumulated water can be easily and directly discharged outside the vehicle, avoiding water retention. Furthermore, by distributing the drainage holes 20b at different positions on the door 20, even under strong wind pressure, water flow can be ensured smoothly, reducing drainage obstacles.

[0060] In a specific embodiment, the size of the drain hole 20b is 10. 20mm to 15mm The size should be selected between 25mm and 10mm to avoid the drain hole 20b being too small, which would prevent water from draining properly due to surface tension, and also to avoid the drain hole 20b being too large, which would affect the structural strength of the door 20. The size of the drain hole can be 10mm. 20mm, 15 20mm, 20 20mm, 10 23mm, 10 25mm and 15 25mm.

[0061] like Figure 3 As shown, the car door 20 includes an inner panel 21 and an outer panel 22, with an inner cavity 20a formed between the inner panel 21 and the outer panel 22. A drainage hole 20b is located at the bottom of the inner panel 21. This arrangement allows water accumulated at the bottom of the car door 20 to be drained in a timely manner.

[0062] In some embodiments of this application, the vehicle sealing system includes multiple doors 20, multiple sealing strips 30, and multiple first sensors 41. The number of doors 20, sealing strips 30, and first sensors 41 are the same, and each door, sealing strip 30, and first sensor 41 is configured in a one-to-one correspondence. In use, the drive unit 42 can drive multiple sealing strips 30 to switch synchronously, or it can control the sealing strip 30 on each door 20 to switch individually. Specifically, the controller 43 controls the state of the sealing strip 30 on each door 20 based on different detection data from the multiple first sensors 41. When one or more sealing strips 30 need to switch states, the controller 43 controls the opening and closing of the control valve corresponding to the sealing strip 30 and drives the corresponding drive unit 42 to pump or extract air. Through the above settings, the sealing or drainage state of the sealing strip 30 on each door 20 can be controlled more accurately, improving the accuracy and control efficiency of the vehicle sealing system.

[0063] In this embodiment, the air pump has an air port 42a for intake or exhaust, and a filter is provided at the air port 42a. When the air pump is working, the gas contains dust, particles, and water vapor. The filter effectively intercepts the dust, particles, and water vapor that accompany the gas, preventing impurities from affecting the normal operation of the air pump and the performance of the sealing strip 30, and ensuring that the air entering the air pump is clean. In some embodiments, the filter is made of sheet sponge or activated carbon pack, which can be replaced regularly to ensure filtration efficiency and cleaning ability.

[0064] In this embodiment, the sealing strip 30 is switched between a sealing state and a drainage state through the following steps:

[0065] First, based on the detection data from the first sensor 41 and the second sensor, the controller 43 determines whether the humidity of the inner cavity 20a or the amount of rain outside the vehicle exceeds the detection threshold.

[0066] If the detection threshold is exceeded, the controller 43 controls the control valve and air pump to pump air from the sealing strip 30 and detects the pressure data in the cavity through the pressure sensor. After the sealing strip 30 reaches the set contraction pressure, the controller 43 controls the control valve and air pump to close, thereby maintaining the stability of the air pressure in the cavity and entering the drainage state, so that the water in the cavity can be smoothly discharged out of the vehicle.

[0067] If the detection threshold is not exceeded, the controller 43 keeps the sealing strip 30 sealed or controls the control valve and air pump to pump air into the sealing strip 30 and detects the pressure data in the cavity through the pressure sensor. After the sealing strip 30 reaches the set expansion pressure, the control valve and air pump are closed to maintain the stability of the air pressure in the cavity, thereby switching to a sealed state to prevent external impurities, noise, etc. from entering the vehicle and thus maintain a good driving experience.

[0068] The technical solution provided in this application has the following advantages:

[0069] 1. By switching between sealing and drainage states of the sealing strip 30 in this solution, the problem that traditional sealing strips cannot effectively drain water while achieving a good sealing effect can be effectively solved. Especially in rainy weather with water accumulation, this solution can effectively avoid problems such as door corrosion, electrical component failure, or odor caused by water accumulation in the inner cavity 20a.

[0070] 2. By introducing the cooperation of the first sensor 41, the drive unit 42 and the controller 43, the vehicle sealing system can be automatically controlled without manual intervention, ensuring good sealing performance, drainage effect and comfortable riding experience of the vehicle under various conditions.

[0071] 3. By controlling the opening and closing of the pipeline through the control valve and the pressure sensor to detect the air pressure in the airbag chamber in real time, the air pressure in the sealing strip 30 chamber is kept within an appropriate range, avoiding overpressure that could damage the air pump and weaken the connection between the sealing strip 30 and the base, thus further improving the durability and stability of the vehicle sealing system.

[0072] 4. A second sensor is set up to cooperate with the first sensor 41 to detect the rainfall data outside the vehicle and the humidity data inside the vehicle, so that the controller 43 can more accurately determine whether the state of the sealing strip 30 should be switched, and the vehicle sealing system can more accurately grasp the changes in the surrounding environment and switch the state of the sealing strip 30 in a timely and accurate manner.
