Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of sealing devices, in particular to a sealing strip, a sealing strip system and a vehicle. BACKGROUND

[0002] With the improvement of people's living standards, people's requirements for private cars are getting higher and higher, from the basic needs to the expectation of improving the driving experience. The driving experience involves many aspects, such as noise, door opening and closing quality, water safety and the like. The performance of the door sealing strip has a direct impact on many of the above aspects. The door sealing strip can prevent rain, water, dust and polluted gas from entering, and can also play a role in sound insulation, noise reduction, vibration absorption and reduction. One of the main indicators that can reflect the mechanical properties of the sealing strip is the sealing reaction force.

[0003] In the process of manufacturing a new car, the door posture is adjusted, and the sound quality of opening and closing the door is basically determined. However, as the use time of the car increases, the sealing reaction force of the sealing strip will inevitably decay due to its material properties. In addition, the temperature also has an impact on the sealing reaction force of the sealing strip, and the impact of high temperature and high cold weather on the sealing reaction force is within ±20%. Changes in the sealing reaction force of the sealing strip will cause changes in the opening and closing quality, and in severe cases, wind noise and other problems will occur. The conventional design of the sealing strip cannot maintain the ideal design state when the sealing reaction force changes, and then the use effect becomes poor. The conventional design of the sealing strip only considers ordinary waterproofing and is not suitable for use in the door waterproofing of vehicles in deep water areas.

[0004] An improved way is to inflate and deflate the sealing strip, but under the limitation of the mechanical structure of the door and the like, the state of the sealing strip inside the air pressure is unstable during the fitting process, and the performance is insufficient. CONTENT OF THE INVENTION

[0005] Therefore, it is necessary to provide a sealing strip, a sealing strip system and a vehicle in view of at least one of the above problems.

[0006] In one aspect, the present disclosure provides a sealing strip, which comprises: a mounting portion, the cross section of the mounting portion defining a first direction and a second direction intersecting each other; a first bubble tube comprising a first part and a second part, the first part being connected to the mounting portion along the first direction, and the second part protruding from the mounting portion along the second direction; the first bubble tube is provided with a first sealing cavity communicating in the first part and the second part, and the first bubble tube is provided with a gas hole capable of being closed and opened, the gas hole being used for gas input or exhaust of the first sealing cavity; and a second bubble tube comprising a third part, a fourth part and a fifth part, the third part being connected to the first part along the first direction, the fourth part protruding from the mounting portion along the second direction, and the fifth part protruding from the third part along the first direction; the second bubble tube is provided with a second sealing cavity communicating in the third part, the fourth part and the fifth part.

[0007] By setting the first bubble tube with the air hole, the sealing reaction force of the sealing strip can be adjusted by being supplied with air or being discharged with air, so that the sealing strip can well adapt to different sealing requirements. By setting the fifth part protruding from the third part in the overall structure, the second bubble tube can reliably deform and buffer and achieve sealing under different sealing requirements. The second bubble tube plays a role in deformation buffering, the sealing strip has good consistency in stress deformation, and the pressure of the first bubble tube is stable. The sealing strip is reliable in sealing; and good operation experience can be provided in the process of being compressed and sealed.

[0008] In some embodiments, the fourth part protrudes from the second part along the second direction.

[0009] In this way, the second bubble tube is deformed and buffered, and the stability of the first bubble tube is ensured.

[0010] In some embodiments, the fifth part has an angular cross section.

[0011] In this way, the second bubble tube gradually deforms, and sound absorption and force relief are more delicate and hierarchical.

[0012] Exemplarily, the second bubble tube further includes a sixth part connected to the sharp corner of the fifth part along the first direction.

[0013] In this way, the sealing strip can be used to contact the glass, which is conducive to further reducing the abnormal sound.

[0014] In some embodiments, the air hole is formed in the second part.

[0015] In this way, the first bubble tube can be filled with air or discharged with air, and the sealing strip structure is compact.

[0016] In another aspect, the disclosure provides a sealing strip system, which includes the sealing strip described above, an air pressure regulator connected to the air hole, and an air pressure sensor for detecting the air pressure of the first bubble tube.

[0017] By setting the air pressure sensor, the air pressure of the first bubble tube can be obtained, and the air pressure of the first bubble tube can be adjusted and maintained according to different use environments and different sealing requirements.

[0018] In some embodiments, the sealing strip system further includes a temperature sensor for detecting the temperature of the sealing strip.

[0019] By setting the temperature sensor, the temperature of the sealing strip can be obtained, and the sealing reaction force of the sealing strip can be obtained based on, for example, experimental data, and then the air pressure of the first bubble tube can be accurately adjusted to compensate for changes due to temperature, so as to achieve a sealing strip with good use effect.

[0020] In some embodiments, the sealing strip system further comprises a wading sensor configured to detect a wading depth of the lowest point of the sealing strip.

[0021] By providing the wading sensor, the wading depth of the sealing strip can be obtained, and the sealing force that the sealing strip should have for sealing can be known based on, for example, experimental data, and then the air pressure of the first bubble tube can be effectively increased to improve the sealing ability of the sealing strip.

[0022] In some embodiments, the sealing strip system further comprises an alarm configured to alarm when the wading depth exceeds a threshold value.

[0023] In this way, the alarm can also be triggered for abnormal situations.

[0024] In some embodiments, the sealing strip system further comprises a controller electrically connected to the air pressure sensor and the air pressure regulator.

[0025] In this way, the sealing strip can be automatically controlled.

[0026] In another aspect, the present disclosure provides an automobile, comprising: a vehicle body; a vehicle door connected to the vehicle body; and the sealing strip system as described above, the sealing strip being arranged on the vehicle body or the vehicle door to achieve sealing between the vehicle body and the vehicle door.

[0027] In this way, the vehicle door and the vehicle body can achieve better sealing effect. For example, when the automobile is wading, the air pressure of the first bubble tube can be increased to improve the sealing ability; for example, when the air temperature changes, the air pressure of the first bubble tube can be adjusted to ensure the door closing effect; and the sealing force can be controlled to achieve better door opening and closing sound quality.

A layer can extend horizontally, vertically, and / or along a tapered surface. A layer can be an area of uniform or non-uniform continuous structure that can have a thickness perpendicular to the direction of extension that is no greater than the thickness of the continuous structure. A layer can include multiple layers, which can be stacked or can be discrete. The shapes of various regions, layers, and their relative sizes and positions in the drawings are exemplary only, and actual variations can occur due to manufacturing tolerances or technical limitations, and designs can be adjusted according to actual needs.

[0045] Reference is made to Figure 1 , Figure 2 and Figure 3 wherein Figure 1 andFigure 2 A sealing strip system of the present disclosure is shown, Figure 3 A sealing strip of the present disclosure is shown. In an exemplary embodiment, the sealing strip system 1100 comprises a sealing strip 1 and an air pressure regulator 2. For the convenience of description, a spatial rectangular coordinate system XYZ is established.

[0046] Reference Figure 3 The sealing strip 1 can extend based on a cross section of substantially the same shape, Figure 3 The cross section shown can be parallel to the YZ plane, wherein the first direction can be parallel to the Y-axis direction and the second direction can be parallel to the Z-axis direction. Specifically, the Y-axis positive direction and the first direction can be from right to left, and the Z-axis positive direction and the second direction can be from bottom to top. Figure 3 The sealing strip 1 can be used between two pieces to be sealed, which have two surfaces to be sealed opposite along the Y-axis direction, and the sealing strip 1 is clamped between the two surfaces to be sealed. The sealing strip 1 is used to be extruded along the first direction, which can achieve a better sealing effect.

[0047] The sealing strip 1 comprises a mounting portion 11, a first bubble tube 12 and a second bubble tube 13. The mounting portion 11, the first bubble tube 12 and the second bubble tube 13 are sequentially arranged along the first direction. The mounting portion 11 can be connected to one piece to be sealed, and the sealing strip 1 can abut against the other piece to be sealed.

[0048] Reference Figure 3 The sealing strip 1 can be a one-piece structure, which forms a cavity inside, and the cavity extends along the extension direction of the sealing strip 1. The first bubble tube 12 and the second bubble tube 13 respectively form their own cavities, and the first bubble tube 12 can be provided with a first sealing cavity 120, and the second bubble tube 13 can be provided with a second sealing cavity 130. The first bubble tube 12 and the second bubble tube 13 can not be communicated. As shown in Figure 1 and Figure 2 The sealing strip 1 is often annular, and it can be understood that the shapes of the cross sections at different positions of the sealing strip 1 can be similar, but the actual attitude in space will be shifted.

[0049] The first bubble tube 12 comprises a first portion 121 and a second portion 122. The first portion 121 is connected to the mounting portion 11 along the first direction. The second portion 122 protrudes from the mounting portion 11 along the second direction, as shown in the cross section shown in Figure 3 The position of the second portion 122 in the cross section protrudes upward from the mounting portion 11 along the Z-axis direction. The first bubble tube 12 is provided with a gas hole, which can be used to communicate with the air pipe 21. Exemplarily, the gas hole is provided in the second portion 122, and the air pipe 21 extends into the first bubble tube 12 from the side of the mounting portion 11, which makes the structure of the sealing strip 1 compact and also facilitates the gas supply or exhaust of the first bubble tube 12.

[0050] The second bubble tube 13 comprises a third portion 131, a fourth portion 132 and a fifth portion 133. Referring to Figure 3 The third portion 131 is connected to the first portion 121 and indirectly connected to the mounting portion 11. The third portion 131 can be shorter than the first portion 121, specifically, the lower end of the third portion 131 can be higher than the first portion 121 along the Z-axis direction. The fourth portion 132 protrudes from the mounting portion 11 along the second direction. The fourth portion 132 can be connected to the second portion 122. The fifth portion 133 protrudes from the third portion 131 along the first direction. The fifth portion 133 is located at the third portion 131 and can not cover the position of the fourth portion 132. When the sealing strip 1 is extruded, the fifth portion 133, the third portion 131, the first portion 121 and the mounting portion 11 can transmit force along the first direction and can be flattened to a certain extent.

[0051] The first bubble tube 12 can be provided with one gas hole for air intake and air exhaust, or can be provided with multiple gas holes for work respectively. After air intake, the first bubble tube 12 can increase the air pressure, or increase the air pressure when the same compression amount is increased; after a certain amount of gas is exhausted, the air pressure of the first bubble tube 12 will decrease. Adjusting the air pressure of the first bubble tube 12 can adjust the overall sealing reaction force of the sealing strip 1, so that the sealing strip 1 can adapt to different sealing requirements. Optionally, the air tube 21 can be detachably connected to the corresponding gas hole, or can be sealingly fixed to a gas hole. The gas hole can be closed and opened. The state of the gas hole can be switched by controlling the air tube 21 connected to the gas hole, for example, the gas hole and the first sealing cavity 120 can be closed by closing the air tube 21, and the gas hole can be opened by opening the air tube 21.

[0052] When the predetermined distance of the two sealing objects is small and the sealing reaction force of the sealing strip 1 is large, the first bubble tube 12 can be exhausted, which is beneficial to the movement of the two sealing objects along the first direction to the predetermined distance. When the two sealing objects need to achieve high sealing performance, the first bubble tube 12 can be inflated to increase the sealing reaction force.

[0053] Referring to Figure 5 In an exemplary embodiment, the sealing strip 1 is applied in a vehicle 1000. For example, the sealing strip 1 is applied between a vehicle body 1200 and a vehicle door 1300, and the vehicle door 1300 can be opened and closed. Figure 5 Part of the structure of the vehicle door assembly of the vehicle 1000 is briefly shown in the figure. The vehicle body 1200 can include a side wall, and the vehicle door 1300 can include a vehicle door panel.

[0054] Referring to Figure 6 and Figure 7 , Figure 7The sealing strip 1 is compressed, and the sealing strip 1 is in a state of high pressure. The second bubble tube 13 plays a role of deformation buffer, the sealing strip 1 is deformed uniformly under force, and the pressure of the first bubble tube 12 is stable during compression. The sealing strip 1 is reliable in sealing. The sealing strip 1 can provide a better operation experience during compression and sealing.

[0055] Reference Figure 8 , wherein the vehicle body 1200 is not shown, Figure 8 The sealing strip 1 and the vehicle door assembly are in a state of low pressure. The first sealing cavity 120 of the first bubble tube 12 is less expanded, but the second part 122 can still well support the fourth part 132. The pressure of the first bubble tube 12 is stable during compression. The second bubble tube 13 receives less pressure along the Y-axis direction, and the fifth part 133 can still be deformed to fit the vehicle door 1300; the second bubble tube 13 is less deformed along the Z-axis direction, but the fourth part 132 and the fifth part 133 still have sufficient sealing surfaces. The second bubble tube 13 plays a role of deformation buffer, and the sealing strip 1 is deformed uniformly under force. The sealing strip 1 is reliable in sealing. The sealing strip 1 can provide a better operation experience during compression and sealing.

[0056] In some embodiments, the fourth part 132 protrudes from the second part 122 along the second direction. The fourth part 132 and the fifth part 133 can form two fulcrums, which are beneficial to deformation buffer of the second bubble tube 13 and ensure stability of the first bubble tube 12.

[0057] In some embodiments, the fifth part 133 has an angular cross section. During compression of the sealing strip 1, the fifth part 133 is gradually flattened, the contact surface of the second bubble tube 13 gradually increases, which is beneficial to gradual deformation of the second bubble tube 13 and gradual force transmission to the first bubble tube 12, and the sealing strip 1 absorbs sound and unloads force more finely and hierarchically. Exemplarily, the third part 131 also has an angular shape, and the opening thereof faces the fourth part 132. The third part 131 and the fifth part 133 constitute a shearing type, which can be opened when not being pressed, and the third part 131 and the fifth part 133 tend to be flattened and overlapped when being pressed.

[0058] Reference Figure 3 , Figure 7 and Figure 8 The second bubble tube 13 can further include a sixth part 134 connected to the fifth part 133 along the first direction. Exemplarily, the sixth part 134 extends along the first direction and deviates from the fourth part 132 in the second direction. The sixth part 134 can be connected to the sharp corner of the fifth part 133. When the sealing strip 1 is pressed, the sixth part 134 can be pressed first and drive the fifth part 133. The sealing strip 1 configured with the sixth part 134 can reduce abnormal sound when impacted and pressed by two sealing objects.

[0059] Exemplarily, the second bubble tube 13 can further include a seventh portion 135. The seventh portion 135 is connected to the fourth portion 132 along the first direction, as shown, at the upper left corner of the fourth portion 132. The seventh portion 135 is spaced apart from the fifth portion 133, and the seventh portion 135 is shorter than the fifth portion 133 relative to the fourth portion 132 along the first direction. Figure 3

[0060] Referring to Figures 1 to 4 , the present disclosure provides a seal strip system. The seal strip system 1100 can be applied in a vehicle 1000. The seal strip system 1100 includes a seal strip 1, an air pressure regulator 2, and an air pressure sensor 3. The seal strip 1 can be the seal strip 1 described above.

[0061] The air pressure regulator 2 is connected to the air hole. Exemplarily, the air pressure regulator 2 is an air pump, which can supply and exhaust air to the first bubble tube 12 through the air hole. The air pressure regulator 2 can also include multiple components, such as an air pump for air supply and an exhaust valve for air exhaust.

[0062] The air pressure sensor 3 is used to detect the air pressure of the first bubble tube 12. By providing the air pressure sensor 3, the air pressure of the first bubble tube 12 can be obtained, and the air pressure of the first bubble tube 12 can be adjusted and maintained according to different use environments and different sealing requirements.

[0063] In combination Figures 5 to 7 , the present disclosure provides a vehicle 1000, which includes a vehicle body 1200, a vehicle door 1300 connected to the vehicle body 1200, and the seal strip system 1100 described above. The seal strip 1 is arranged on the vehicle body 1200 or the vehicle door 1300 to achieve the sealing of the vehicle body 1200 and the vehicle door 1300.

[0064] The use environment of the vehicle 1000 is various. In a normal temperature environment, the seal strip 1 is in a normal state, can have a suitable sealing reaction force, and the vehicle door 1300 is easy to close in place, and has a good sound quality when the vehicle door 1300 is opened or closed. In a high temperature environment, the seal strip 1 is affected by temperature, the sealing reaction force is weakened, resulting in an increase in high frequency sound of the door closing sound and a decrease in sound quality. The loudness of the door closing sound is increased by 3 sone to 7 sone, and the sharpness is increased by 0.2 acum to 0.4 acum. By inflating the seal strip 1 to increase the sealing reaction force, the loudness and sharpness of the door closing sound can be reduced to improve the sound quality.

[0065] In a low temperature environment, the sealing reaction force of the seal strip 1 is large and not easy to compress, which can cause the vehicle door 1300 to be difficult to close. By deflating the seal strip 1, the sealing reaction force of the seal strip 1 can be reduced, which is helpful to improve the closing effect.

[0066] ​When, for example, car 1000 is wading through water, the air pressure of the first bubble tube 12 can be increased to improve the sealing ability. The door 1300 and the body 1200 can achieve a better sealing effect, preventing water from seeping out between the sealing strip 1 and the sheet metal, thereby preventing water from entering the car. After car 1000 leaves the water, the pressure of the first bubble tube 12 can be reduced to restore normal use.

[0067] The sealing strip system 1100 can adjust the state of the sealing strip 1 at any time, thereby effectively meeting changing usage requirements.

[0068] For example, the mounting part 11 is mounted on the side panel of the vehicle body 1200. The second bubble tube 13 is used to abut against the door sheet metal of the door 1300. The vehicle 1000 also includes a floor 1400, see reference. Figure 7 The edge of the floor 1400 can also be clamped within the mounting section 11. (Reference) Figure 3 The mounting part 11 may include a reinforcing plate 111, the reinforcing plate 111 having a U-shaped cross-section, which improves installation reliability. The sealing strip 1 may also include a clamping edge 14, which can improve the stability of the sealing strip 1.

[0069] The pressure regulator 2 can be controlled manually, for example, by having a button. The user presses the button according to the sealing requirements, and the pressure regulator 2 then controls the pressure of the first bubble tube 12. The button can also be considered as the controller 7. The button can be a mechanical button or a touch screen. The touch screen can also be used to display the pressure data of the pressure sensor 3.

[0070] refer to Figure 5 and Figure 6 In some embodiments, the door sheet metal of the vehicle door 1300 has a semi-enclosed structure, and the window is not surrounded by the door sheet metal when it is raised. The glass window can contact the sealing strip 1 to achieve a seal. Exemplarily, the shape or size of the cross-section of the sealing strip 1 can also be different at different positions. For example, a sixth part 134 can be designed for the position corresponding to the window. When the vehicle door 1300 is closed, the window contacts the sealing strip 1, and the abnormal noise is small.

[0071] In other embodiments, the door 1300 may also be a full-frame structure, with the door sheet metal surrounding the glass window, and the sealing strip 1 used to fit the door sheet metal.

[0072] The sealing strip 1 can be wrapped around the door 1300 along the body 1200. Exemplarily, the sealing strip system 1100 can include two sealing strips 1 connected as one at one door, or the sealing strip 1 is divided into two sections. The cavities of the two sealing strips 1 can not be communicated, and then the two sealing strips 1 can be inflated and deflated respectively, and can have different air pressures. For example, the door panel and the window can correspond to different sections of the sealing strip 1, and the sealing strip 1 has different inflation pressures at different sections, for example, the pressure at the door panel is larger; of course, the same pressure can also be achieved in other cases.

[0073] Reference Figure 4 In some embodiments, the sealing strip system 1100 further includes a controller 7, which can be a car machine, and can include a display screen, a processing unit and a storage unit. The controller 7 is electrically connected to the air pressure sensor 3 and the air pressure regulator 2, which is beneficial to automatically control the sealing strip 1. The controller 7 can control the air pressure regulator 2 to work, for example, to inflate / deflate the first bubble tube 12, when the air pressure sensor 3 shows that the air pressure reaches the set value, the display screen can prompt that the inflation / deflation is completed, and the air pressure regulator 2 can automatically stop inflation / deflation.

[0074] In some embodiments, the sealing strip system 1100 further includes a temperature sensor 4, which can be electrically connected to the controller 7. The temperature sensor 4 is used to detect the temperature of the sealing strip 1. The sealing force of the sealing strip 1 can change with the temperature, and the data can be stored in the storage unit, and then the processing unit can accurately adjust the air pressure of the first bubble tube 12 to compensate for the change due to the temperature, so as to achieve a good sealing effect of the sealing strip 1.

[0075] The sealing strip system 1100 further includes a wading sensor 5, which can be electrically connected to the controller 7. The wading sensor 5 is used to detect the wading depth of the lowest point of the sealing strip 1. The sealing force of the sealing strip 1 can be obtained based on experimental data, and the air pressure of the first bubble tube 12 can be effectively increased to improve the sealing ability of the sealing strip 1. In addition, the sealing can also be achieved with the highest sealing effect.

[0076] The sealing strip system 1100 can further comprise an alarm 6, which can be electrically connected to the controller 7. The alarm 6 is used to alarm when the wading depth exceeds a threshold value. When the wading depth exceeds 300 mm, the alarm 6 can alarm, for example, the display screen displays an alarm signal. The controller 7 can be operated by the user to make the air pressure regulator 2 inflate; it can also be automatically started to inflate the air pressure regulator 2 after, for example, 5 seconds of alarm, and as the pressure of the sealing strip 1 is greater than the external water pressure, it can play a water-blocking sealing role. The alarm can be released. After the car 1000 drives away from the wading area, or when the wading depth is lower than the threshold value, the air pressure regulator 2 can be controlled to deflate the sealing strip 1, and when the value of the air pressure sensor 3 returns to the set value during deflation, the deflation can be stopped.

[0077] The car 1000 has good door opening and closing quality, good water tightness, high technology of the door assembly, and good riding experience.
