Description

Technical Field

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

[0002] The tailgate sealing strip is an important sealing component of a vehicle, used for waterproofing, sound insulation, dust prevention, and shock absorption. The sealing strip provides elastic cushioning to reduce the impact force when closing the door.

[0003] In related technologies, the sealing strip is formed entirely of elastic material, and when the tailgate is closed, the sealing strip seals between the tailgate and the vehicle body through elastic deformation.

[0004] However, when the vehicle is driving on special road surfaces, the tailgate will vibrate relative to the vehicle body. The vibrating tailgate will push the air inside the vehicle body, generating primary sound pressure waves, causing discomfort such as ear stuffiness for the users inside the vehicle, resulting in a technical problem of poor vehicle comfort. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a sealing strip and a vehicle. The sealing strip can not only play a sealing role between the vehicle body and the tailgate, but also provide rigid support when the tailgate is impacted by the sealing strip, so as to reduce the vibration amplitude of the tailgate.

[0006] In a first aspect, this application provides a sealing strip for sealing a first structure and a second structure. The sealing strip includes: a body for connecting the first structure, the body being capable of elastic deformation; and a non-Newtonian fluid layer disposed on the body and located outside the body, wherein the non-Newtonian fluid layer is configured to contact the second structure when the sealing strip seals the first structure and the second structure.

[0007] This application addresses the technical problem in related technologies where a vibrating tailgate generates primary sound pressure waves inside the vehicle body, causing discomfort such as ear fullness for occupants and poor vehicle comfort. This is achieved by setting a non-Newtonian fluid layer on the outer side of the main body and contacting the tailgate through this non-Newtonian fluid layer. The shear-thickening properties of the non-Newtonian fluid effectively support the vibrating tailgate, reducing the impact transmitted to the main body and minimizing the deformation amplitude of the main body. Furthermore, this application optimizes the sealing strip structure, balancing the sealing and support performance of the sealing strip, thereby improving vehicle comfort.

[0008] In some implementations, the body includes a fixing part and a sealing part, the fixing part is used to connect the first structure, and the sealing part is connected to the fixing part; wherein, when the sealing strip seals the first structure and the second structure, the sealing part is configured to be located between the first structure and the second structure, the inner surface of the sealing part encloses a cavity, and a non-Newtonian fluid layer is disposed on the outer surface of the sealing part.

[0009] In some implementations, the sealing part is tubular, and a non-Newtonian fluid layer is disposed on the outer peripheral side of the fixing part and covers the outer peripheral surface of the fixing part.

[0010] In some implementations, the thickness of the non-Newtonian fluid layer is greater than or equal to the thickness of the sealing portion; the thickness of the non-Newtonian fluid layer is greater than or equal to 0.5 mm and less than or equal to 1.1 mm; the thickness of the sealing portion is greater than or equal to 0.4 mm and less than or equal to 1 mm.

[0011] In some implementations, the non-Newtonian fluid layer is detachably disposed within the body.

[0012] In some implementations, a slot is formed inside the non-Newtonian fluid layer, and part of the body is fitted into the slot.

[0013] In some implementations, the body includes a through hole, and a positioning part is provided on the side of the non-Newtonian fluid layer facing the body; wherein, the positioning part includes a shaft segment and a fixing segment, the shaft segment passes through the through hole, and the fixing segment abuts against the side of the body opposite to the non-Newtonian fluid layer.

[0014] In some implementations, there are multiple positioning parts, which are spaced apart along the length of the sealing strip; the positioning parts and the non-Newtonian fluid layer are an integral structure, and the positioning parts are provided with reinforcing ribs.

[0015] In some implementations, a rib is provided on the side of the non-Newtonian fluid layer facing away from the main body, and the rib and the non-Newtonian fluid layer are an integral structure.

[0016] Secondly, this application provides a vehicle comprising: a body; a tailgate hinged to the body; and a sealing strip as described in the first aspect, the body of which is connected to the body, wherein a non-Newtonian fluid layer contacts the tailgate when the tailgate is closed.

[0017] In the vehicle of this application, the same beneficial effect can be achieved by including the sealing strip of the first aspect. That is, the sealing strip can provide rigid support when the tailgate is impacted, thereby reducing the amplitude of tailgate vibration. Attached Figure Description

[0031] The following is a detailed description of this application.

[0032] The vehicle features a trunk space at the rear of the body. The tailgate can rotate relative to the body, and its opening and closing action allows the trunk space to be accessed. A sealing strip is installed on the tailgate or the vehicle body. When the tailgate is closed, the sealing strip acts as a seal between the body and the tailgate, preventing dust, rainwater, and other contaminants from entering the trunk. Furthermore, the sealing strip also blocks external noise between the body and the tailgate, and provides a cushioning effect to reduce the impact of closing the door or the impact of tailgate vibration.

[0033] In related technologies, the sealing strip is integrally molded from an elastic material, such as ethylene propylene diene monomer (EPDM). In this case, the sealing strip can meet the requirements of sealing, sound insulation and shock absorption through elastic deformation.

[0034] The inventors of this application discovered that when a vehicle travels on uneven dirt roads, cobblestone roads, broken roads, or other special road surfaces, the vehicle's bumps cause the tailgate to vibrate frequently. The vibrating tailgate impacts the sealing strip, and under this impact, the elastic sealing strip undergoes significant deformation in a short period of time, causing the tailgate to lose effective support. As a result, the tailgate frequently pushes the air inside the vehicle, generating primary sound pressure waves inside the vehicle. These primary sound pressure waves can cause discomfort such as ear fullness for the users inside the vehicle, damaging the user's riding experience and resulting in a technical problem of poor vehicle comfort.

[0035] To address the technical problem that the vibrating tailgate pushes the air inside the vehicle body, generating primary sound pressure waves that cause discomfort such as ear fullness for the vehicle occupants, resulting in poor vehicle comfort, this application provides a sealing strip 1 and a vehicle 4.

[0036] The sealing strip 1 of this application embodiment can be applied between the body and the tailgate of the vehicle 4. It can not only meet the sealing, sound insulation and shock absorption requirements of the sealing strip 1, but also provide effective support for the vibrating tailgate when the vehicle 4 is bumpy.

[0037] Reference Figure 1 This is a schematic diagram of the structure of the sealing strip 1 according to an embodiment of this application. The sealing strip 1 of this embodiment is used to seal the first structure 2 and the second structure 3. The sealing strip 1 includes: a body 11 for connecting the first structure 2, the body 11 being capable of elastic deformation; and a non-Newtonian fluid layer 12 disposed on the body 11 and located on the outside of the body 11. When the sealing strip 1 seals the first structure 2 and the second structure 3, the non-Newtonian fluid layer 12 is configured to contact the second structure 3.

[0038] Reference Figure 5This is a schematic diagram of the structure of vehicle 4 according to an embodiment of this application. When the sealing strip 1 is applied to vehicle 4, the first structure 2 can be the vehicle body, and the second structure 3 can be the tailgate. In this case, the sealing strip 1 can seal between the vehicle body and the tailgate, and provide support for the tailgate.

[0039] In another case, the first structure 2 can be the vehicle body and the second structure 3 can be the side door. In this case, the sealing strip 1 can seal between the vehicle body and the side door, and provide support for the side door.

[0040] In this regard, the first structure 2 can be selected based on the sealing requirements of the vehicle body. This application does not impose a rigid limitation on the combination of the first structure 2 and the second structure 3, as long as the corresponding sealing requirements can be met on the vehicle 4.

[0041] Based on this, the sealing strip 1 includes a body 11 and a non-Newtonian fluid layer 12. The body 11 is formed by elastic material, such as by injection molding of EPDM. Therefore, the body 11 can generate elastic deformation when subjected to pressure, thereby satisfying the sealing requirements of the gap between the first structure 2 and the second structure 3 through deformation.

[0042] The body 11 connects to the first structure 2, and the non-Newtonian fluid layer 12 is disposed on the outside of the body 11. The body 11 provides positioning and support for the non-Newtonian fluid layer 12. Assembling the body 11 onto the first structure 2 positions the non-Newtonian fluid layer 12 in the designated location. The non-Newtonian fluid layer 12 is formed from a non-Newtonian fluid material, specifically a shear-thickening type. By placing the non-Newtonian fluid layer 12 on the outside of the body 11, it can replace the body 11 in contact with the second structure 3 on the other side. In a sealed state, the non-Newtonian fluid layer 12 is located between the second structure 3 and the body 11, ensuring that the impact of the second structure 3 on the sealing strip 1 acts primarily on the non-Newtonian fluid layer 12.

[0043] Taking the second structure 3 as an example of the tailgate, when the vehicle 4 is driving smoothly, the non-Newtonian fluid layer 12 exhibits a soft, almost liquid-like property, which is relatively compliant and will not affect the normal deformation and sealing function of the main body 11. When the vehicle 4 travels to a special road section and thus experiences bumps, the vibrating tailgate will impact the non-Newtonian fluid layer 12 it comes into contact with in a short time, thereby applying shear force to the non-Newtonian fluid layer 12. Under the action of shear force, the microparticle structure in the non-Newtonian fluid layer 12 quickly interlocks and reorganizes, causing the viscosity to increase and even exhibiting a solid-like property, thereby dispersing and dissipating some of the impact energy and reducing the impact on the main body 11.

[0044] With the impact on the main body 11 reduced, the deformation amplitude of the main body 11 is reduced, which correspondingly reduces the vibration amplitude of the tailgate, and ultimately reduces the pressure amplitude of the tailgate on the air inside the vehicle. This weakens or even eliminates the primary sound pressure wave inside the vehicle, reduces discomfort such as ear stuffiness experienced by the user, and thus optimizes the user's riding experience and improves the user's riding comfort.

[0045] When vehicle 4 returns to a flat road surface, the non-Newtonian fluid layer 12 returns to its original soft fluid state, and the body 11 relies on its resilience to return to its shape before the impact in order to maintain the seal between the first structure 2 and the second structure 3.

[0046] Therefore, this application, by setting a non-Newtonian fluid layer 12 on the outside of the body 11 and contacting the tailgate through the non-Newtonian fluid layer 12, can effectively support the vibrating tailgate by utilizing the shear thickening properties of the non-Newtonian fluid, reduce the impact transmitted to the body 11, and reduce the deformation amplitude of the body 11. This solves the technical problem in related technologies where a vibrating tailgate generates primary sound pressure waves inside the vehicle body, causing discomfort such as ear fullness for users inside the vehicle, resulting in poor vehicle comfort. This also achieves the technical effect of optimizing the structure of the sealing strip 1, taking into account both the sealing performance and support performance of the sealing strip 1, and improving the comfort of the vehicle.

[0047] Specifically, the materials of the non-Newtonian fluid layer 12 include: polyethylene glycol suspension, silicone oil + nanoparticles (such as silicon carbide), and polyborosiloxane. These materials have the property of hardening upon impact and are suitable as protective coatings.

[0048] In one embodiment of this application, the non-Newtonian fluid layer 12 can be formed by an in-mold encapsulation process, the process steps of which are as follows: Step 1: Fabricate non-Newtonian fluid functional gel sheets. Specifically, mix non-Newtonian fluid with thermoplastic polyurethane or silicone carrier, and then use casting or calendering processes to form solid flexible gel sheets or films with certain strength and shape.

[0049] Step 2: Fix the gel sheet. Specifically, the pre-formed non-Newtonian fluid gel sheet is precisely laid in the cavity of the injection mold and its position is fixed.

[0050] Step 3: Secondary injection molding. Specifically, the mold is closed, and a thermoplastic elastomer with good compatibility with the gel sheet is injected and wrapped around the body 11 and the outer layer of the gel sheet through an injection molding machine.

[0051] The high pressure and high temperature of injection molding will firmly bond the thermoplastic elastomer to the gel sheet and the surface of the body 11, thereby completely encapsulating the non-Newtonian fluid layer 12 between the thermoplastic elastomer and the body 11.

[0052] In one embodiment of this application, the non-Newtonian fluid layer 12 can be formed by coating and curing, and the process steps are as follows: Step 1: Treat the surface of the body 11, specifically by plasma treatment or chemical primer such as silane coupling agent to enhance surface activity and improve adhesion.

[0053] Step 2: Coat the body 11 with a non-Newtonian fluid, specifically by spraying, impregnating or scraping the body 11 with a non-Newtonian fluid.

[0054] Step 3: Curing the non-Newtonian fluid, specifically by UV curing or heat curing (drying the solvent at 80~120℃).

[0055] Step 4: Apply a protective layer to the outside of the cured non-Newtonian fluid, specifically by covering it with a transparent elastomer to prevent the non-Newtonian fluid from drying out or becoming contaminated.

[0056] Reference Figure 1 , Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the body 11 of the sealing strip 1 according to an embodiment of this application. In some embodiments of this application, the body 11 includes: a fixing part 111 for connecting the first structure 2; and a sealing part 112 connected to the fixing part 111. When the sealing strip 1 seals the first structure 2 and the second structure 3, the sealing part 112 is configured to be located between the first structure 2 and the second structure 3. The inner surface of the sealing part 112 encloses a cavity 113, and a non-Newtonian fluid layer 12 is disposed on the outer surface of the sealing part 112.

[0057] In this embodiment, the body 11 includes a fixing part 111 and a sealing part 112. The fixing part 111 and the sealing part 112 are connected. After the sealing strip 1 is assembled, the fixing part 111 is fixed to the first structure 2, and the non-Newtonian fluid layer 12 is fixed to the outside of the sealing part 112. When the sealing strip 1 seals the first structure 2 and the second structure 3, the non-Newtonian fluid layer 12 and the sealing part 112 are located between the second structure 3 and the fixing part 111, and the non-Newtonian fluid layer 12 is located between the second structure 3 and the sealing part 112.

[0058] When the second structure 3 impacts the sealing strip 1 due to vibration, the non-Newtonian fluid layer 12 located between the second structure 3 and the sealing part 112 can absorb part of the impact energy, thereby reducing the deformation amplitude of the sealing part 112. The sealing part 112 fills the space between the second structure 3 and the fixing part 111, reducing the deformation amplitude of the sealing part 112, which in turn reduces the vibration amplitude of the second structure 3 relative to the first structure 2, thereby improving the stability of the second structure 3 and reducing the amplitude of the second structure 3. This solves the technical problem that primary sound pressure waves are easily generated inside the vehicle, causing discomfort such as ear fullness for users inside the vehicle, and resulting in poor comfort of the vehicle 4.

[0059] Based on this, the sealing part 112 has a hollow structure, and the inner surface of the sealing part 112 encloses a cavity 113. By making the sealing part 112 a hollow structure, the deformation range of the sealing part 112 can be increased, allowing the sealing part 112 to effectively fill the gap between the first structure 2 and the second structure 3 through deformation, thereby improving the sealing effect of the sealing strip 1. Furthermore, by constructing the cavity 113 to increase the deformation range of the sealing part 112, the effect of the sealing strip 1 in absorbing impact can also be improved, thereby improving the stability of the first structure 2 and the second structure 3 while maintaining the sealing effect.

[0060] Specifically, the fixing part 111 and the sealing part 112 are an integral structure, which can be integrally molded by EPDM material. This integral molding process can reduce the process complexity and production cost of the body 11.

[0061] Specifically, the fixing part 111 includes a slot, and a damping structure is provided inside the slot. During the assembly of the sealing strip 1, a portion of the first structure 2 is inserted into the slot. The damping structure provides resistance to prevent the fixing part 111 from falling off, thereby completing the assembly. Optionally, the damping structure is a rib, which is inclined towards the bottom of the slot. Two ribs form a group, with the ends of the two ribs in the same group facing each other. After the first structure 2 is inserted into the slot, the first structure 2 pushes the two ribs apart, and the two ribs abut against the two sides of the first structure 2 respectively to provide resistance.

[0062] Reference Figure 1 and Figure 4 In some embodiments of this application, the sealing part 112 is tubular, and the non-Newtonian fluid layer 12 is disposed on the outer peripheral side of the fixing part 111 and covers the outer peripheral surface of the fixing part 111.

[0063] In this embodiment, the sealing part 112 is tubular, and the inner annular surface of the sealing part 112 surrounds the cavity 113. When the first structure 2 and the second structure 3 compress the sealing part 112, the tubular sealing part 112 undergoes elastic deformation, and the cavity 113 is compressed, thereby absorbing part of the impact.

[0064] By making the sealing part 112 into a tubular shape, on the one hand, the sealing part 112 can be adapted to the narrow sealing space between the tailgate and the vehicle body, thereby improving the sealing effect of the vehicle 4. On the other hand, the tubular structure has excellent compressive strength in its radial direction and has a low probability of collapse, which can provide effective support between the first structure 2 and the second structure 3, thereby improving structural stability while taking into account the sealing requirements.

[0065] Based on this, a non-Newtonian fluid layer 12 is arranged on the outer peripheral surface of the sealing part 112, and the non-Newtonian fluid layer 12 is at least distributed on the side of the sealing part 112 facing away from the fixing part 111, so that the non-Newtonian fluid layer 12 can replace the sealing part 112 in contact with the second structure 3, avoiding direct contact between the sealing part 112 and the second structure 3, thereby forming a protective layer between the sealing part 112 and the second structure 3 that can change its viscosity based on the shear force generated by the impact, and thus absorbing the impact energy when the second structure 3 is subjected to instantaneous impact, solving the technical problem that primary sound pressure waves are easily generated in the vehicle, and that users in the vehicle are prone to ear stuffiness and other discomfort, resulting in poor comfort of the vehicle 4.

[0066] Reference Figure 1 , Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the baffle of the electrode recycling device according to an embodiment of this application. In some embodiments of this application, the thickness of the non-Newtonian fluid layer 12 is ( Figure 3 (as shown in T1) The thickness of the sealing part 112 is greater than or equal to that shown in T1. Figure 4 (as shown in T2); the thickness of the non-Newtonian fluid layer 12 ranges from 0.5 mm to 1.1 mm. The thickness of the sealing part 112 is in the range of 0.4 mm or more and 1 mm or less.

[0067] In this embodiment, within the same region, the thickness of the non-Newtonian fluid layer 12 is greater than or equal to the thickness of the sealing portion 112. Specifically, the larger the diameter of the tubular structure, the worse its resistance to deformation. The thickness of the non-Newtonian fluid layer 12 directly affects its impact resistance. By arranging a non-Newtonian fluid layer 12 of equal or greater thickness on the outside of the sealing portion 112, the non-Newtonian fluid layer 12 can absorb sufficient impact energy, thereby reducing the deformation amplitude of the sealing portion 112 under impact, and correspondingly providing effective support for the second structure 3 in contact with the non-Newtonian fluid layer 12.

[0068] Based on this, the thickness of the non-Newtonian fluid layer 12 must be greater than or equal to 0.5 mm and less than or equal to 1.1 mm. By limiting the thickness of the non-Newtonian fluid layer 12 to greater than or equal to 0.5 mm, the non-Newtonian fluid layer 12 can withstand the impact generated by the tailgate on bumpy roads, thereby effectively solving the technical problem of primary sound pressure waves easily generated inside the vehicle, causing discomfort such as ear fullness for users inside the vehicle, and poor vehicle comfort.

[0069] By limiting the thickness of the non-Newtonian fluid layer 12 to less than or equal to 1.1 mm, the space occupied by the non-Newtonian fluid layer 12 can be reduced while ensuring that the non-Newtonian fluid layer 12 has sufficient impact resistance. On the one hand, this avoids the non-Newtonian fluid layer 12 encroaching on the space of the sealing part 112, ensuring that the performance of the sealing part 112 is not affected. On the other hand, it can prevent the tailgate from being pushed up by the non-Newtonian fluid layer 12, thereby improving the sealing effect of the tailgate on the trunk.

[0070] While ensuring that the thickness of the non-Newtonian fluid layer 12 is greater than or equal to the thickness of the sealing portion 112, the thickness of the sealing portion 112 must be greater than or equal to 0.4 mm and less than or equal to 1 mm. By limiting the thickness of the sealing portion 112 to greater than or equal to 0.4 mm, it can be ensured that the sealing portion 112 can provide sufficient elastic support for the tailgate, preventing the sealing portion 112 from collapsing directly under the pressure of the tailgate. By limiting the thickness of the sealing portion 112 to less than or equal to 1 mm, sufficient space can be reserved for the arrangement of the non-Newtonian fluid layer 12, enabling the non-Newtonian fluid layer 12 to withstand the impact generated by the vibrating tailgate.

[0071] Therefore, by limiting the above-mentioned size range, the sealing strip 1 can take into account both sealing performance and impact resistance. When the vehicle 4 is traveling on a flat road, it can effectively seal through the sealing part 112 of sufficient thickness. When the vehicle 4 is traveling on a bumpy special road section, the non-Newtonian fluid layer 12 reduces the vibration amplitude of the tailgate. This achieves the technical effect of improving the sealing effect of the sealing strip 1 and improving the comfort of the vehicle 4 using the sealing strip 1.

[0072] Preferably, the thickness of the sealing part 112 is 0.7 mm and the thickness of the non-Newtonian fluid layer 12 is 0.8 mm, or the thickness of the sealing part 112 is 0.75 mm and the thickness of the non-Newtonian fluid layer 12 is 0.75 mm, or the thickness of the sealing part 112 is 0.6 mm and the thickness of the non-Newtonian fluid layer 12 is 0.9 mm.

[0073] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the non-Newtonian fluid layer 12 is detachably disposed on the body 11.

[0074] In this embodiment, the non-Newtonian fluid layer 12 and the body 11 are detachably connected.

[0075] The non-Newtonian fluid layer 12 not only needs to contact the second structure 3 to make rice noodles, but also needs to absorb the impact of the second structure 3 on the outside of the body 11. Therefore, the non-Newtonian fluid layer 12 will inevitably suffer wear. By setting a detachable non-Newtonian fluid layer 12, it can be quickly replaced during maintenance without replacing the body 11, thereby reducing the maintenance difficulty and cost of the sealing strip 1.

[0076] On the other hand, by making the non-Newtonian fluid layer 12 a detachable structure, it is possible to manufacture the non-Newtonian fluid layer 12 as a standard part that adapts to the body 11, and to select non-Newtonian fluid layers 12 of different thicknesses and properties for assembly according to different vehicle models. For example, when the sealing strip 1 is applied to a vehicle 4 with a heavy tailgate, a thicker non-Newtonian fluid layer 12 is selected to be assembled on the body 11; when the sealing strip 1 is applied to a vehicle 4 with a light tailgate, a thinner non-Newtonian fluid layer 12 is selected to be assembled on the body 11. This achieves the technical effect of optimizing the manufacturing process of the sealing strip 1 and broadening the application range of the sealing strip 1.

[0077] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, a slot 121 is formed inside the non-Newtonian fluid layer 12, and part of the body 11 is fitted into the slot 121.

[0078] In this embodiment, the non-Newtonian fluid layer 12 is arc-shaped, with an opening on one side, and its inner surface enclosing a groove 121 whose shape is adapted to the sealing portion 112. For example, when the sealing portion 112 is tubular, the groove 121 is correspondingly cylindrical with an opening on one side.

[0079] The non-Newtonian fluid layer 12 can deform when not subjected to instantaneous impact. During assembly, the sealing part 112 is inserted into the slot 121 through the opening, allowing the non-Newtonian fluid layer 12 to be fitted onto the outside of the sealing part 112, thus forming an impact-absorbing protection on the outside of the sealing part 112. Furthermore, the formed non-Newtonian fluid layer 12 has a certain ability to maintain its shape. When not subjected to significant external force, the non-Newtonian fluid layer 12 can be fixed to the outside of the sealing part 112 through the snap-fit ​​relationship between the slot 121 and the sealing part 112. This reduces the structural complexity and production cost of the non-Newtonian fluid layer 12 while still meeting the requirement for its detachability.

[0080] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of the structure of the electrode recycling device according to an embodiment of this application. In some embodiments of this application, the body 11 includes a through hole 114; the non-Newtonian fluid layer 12 is provided with a positioning part 122 on the side facing the body 11. The positioning part 122 includes a shaft section 1221 and a fixing section 1222. The shaft section 1221 passes through the through hole 114, and the fixing section 1222 abuts against the side of the body 11 opposite to the non-Newtonian fluid layer 12.

[0081] In this embodiment, a through hole 114 is provided on the sealing part 112. One end of the through hole 114 is connected to the internal cavity 113, and the other end is connected to the outside of the sealing part 112.

[0082] Based on this, a positioning part 122 is provided on the inner side of the non-Newtonian fluid layer 12. When the non-Newtonian fluid layer 12 encloses the slot 121, the positioning part 122 is located within the slot 121. The positioning part 122 can engage with the through hole 114, thereby fixing the non-Newtonian fluid layer 12 on the outside of the positioning part 122, preventing the non-Newtonian fluid layer 12 from loosening or even falling off, thus achieving the technical effect of improving the positioning accuracy of the non-Newtonian fluid layer 12 and reducing the failure rate of the sealing strip 1.

[0083] Based on this, the fixing part 111 includes a shaft segment 1221 and a fixing segment 1222. One end of the shaft segment 1221 is connected to the inner surface of the non-Newtonian fluid layer 12, and the other end of the shaft segment 1221 is connected to the fixing segment 1222. The shape of the shaft segment 1221 is adapted to the shape of the through hole 114, and the fixing segment 1222 can pass through the through hole 114.

[0084] During assembly, the fixing segment 1222 is inserted from the outside of the sealing part 112 into the through hole 114 until it enters the cavity 113. As it passes through the through hole 114, the fixing segment 1222 folds inward toward the shaft segment 1221. After passing through the through hole 114, it unfolds and abuts against the inside of the sealing part 112. After assembly, the shaft segment 1221 is inserted into the through hole 114. The combination of these two components prevents the non-Newtonian fluid layer 12 from moving radially within the through hole 114. The fixing segment 1222, abutting against the inside of the sealing part 112, also prevents the non-Newtonian fluid layer 12 from moving axially within the through hole 114. This achieves precise positioning of the non-Newtonian fluid layer 12, enabling it to seal and absorb impact at the predetermined installation position. This, in turn, improves the structural stability of the sealing strip 1 and reduces its failure rate.

[0085] Reference Figure 3 In some embodiments of this application, there are multiple positioning parts 122, and the multiple positioning parts 122 are spaced apart in the length direction of the sealing strip 1; the positioning part 122 and the non-Newtonian fluid layer 12 are integral structures, and the positioning part 122 is provided with reinforcing ribs 1223.

[0086] In this embodiment, a plurality of positioning parts 122 are provided on the inner side of the non-Newtonian fluid layer 12, and a plurality of through holes 114 are provided on the sealing part 112. The plurality of through holes 114 correspond one-to-one with the plurality of positioning parts 122. By providing multiple sets of positioning parts 122 and through holes 114, multi-point positioning can be formed between the non-Newtonian fluid layer 12 and the sealing part 112, thereby improving the positioning accuracy of the non-Newtonian fluid layer 12 and thus improving the sealing reliability of the sealing strip 1.

[0087] Multiple sets of positioning parts 122 and through holes 114 are spaced apart along the length of the sealing strip 1. When the sealing part 112 is tubular, the axial direction of the sealing part 112 is the length direction of the sealing strip 1. To match the narrow sealing space between the vehicle body and the tailgate, the sealing strip 1 has a relatively large dimension along its length. By spaced apart multiple sets of positioning parts 122 and through holes 114 along its length, the non-Newtonian fluid layer 12 can be tightly attached to the outer side of the sealing part 112, preventing local areas from lifting up. This improves the sealing reliability of the sealing strip 1 and enhances its impact resistance.

[0088] Based on this, the positioning part 122 and the non-Newtonian fluid layer 12 are integral structures, which are integrally formed by injection molding. This integral structure can reduce process complexity and production costs.

[0089] Specifically, a reinforcing rib 1223 is embedded inside the positioning part 122. The non-Newtonian fluid material is relatively soft when it is not subjected to impact. By setting the reinforcing rib 1223, the positioning part 122 can be supported from the inside, preventing the positioning part 122 from coming out of the through hole 114 due to deformation. This achieves the technical effect of improving the engagement stability between the positioning part 122 and the through hole 114 and improving the structural stability of the non-Newtonian fluid layer 12.

[0090] Reference Figure 1 , Figure 3 and Figure 5 In some embodiments of this application, a rib 1224 is provided on the side of the non-Newtonian fluid layer 12 facing away from the body 11, and the rib 1224 and the non-Newtonian fluid layer 12 are an integral structure.

[0091] In this embodiment, a rib 1224 is provided on the outer side of the non-Newtonian fluid layer 12. The rib 1224 extends toward the side opposite to the fixing part 111 relative to the sealing part 112. After the sealing strip 1 is assembled, the rib 1224 faces toward the side where the second structure 3 is located. When the sealing strip 1 seals the first structure 2 and the second structure 3, the rib 1224 fits against the second structure 3 and is located between the non-Newtonian fluid layer 12 and the second structure 3.

[0092] As an outward structure of the non-Newtonian fluid layer 12, the rib 1224 will first come into contact with the second structure 3 as the second structure 3 approaches the first structure 2, and deform under the pressure of the second structure 3. Finally, the deformation will fill the gap between the non-Newtonian fluid layer 12 and the second structure 3, thereby reducing the probability of gaps appearing between the first structure 2 and the second structure 3, and thus achieving the technical effect of improving the sealing reliability of the first structure 2 and the second structure 3.

[0093] Specifically, the rib 1224 and the non-Newtonian fluid are an integral structure, which can be integrally formed by injection molding. This injection molding process can reduce process complexity and production cost. Moreover, compared with elastic materials such as EPDM, the non-Newtonian fluid material has a better filling effect on gaps and can enhance the sealing performance of the sealing strip 1.

[0094] Specifically, a support rib can be embedded in the protruding rib 1224. The support rib is elastic. By setting the support rib in the protruding rib 1224, the elasticity of the support rib can drive the protruding rib 1224 to rebound, so that after the second structure 3 separates from the protruding rib 1224, the protruding rib 1224 can be raised again, thereby improving the sealing reliability of the sealing strip 1.

[0095] Reference Figure 5 In some embodiments of this application, a vehicle 4 is proposed, which includes: a body; a tailgate hinged to the body; a sealing strip 1 in any of the above embodiments, the body 11 of which is connected to the body, and a non-Newtonian fluid layer 12 in contact with the tailgate when the tailgate is closed.

[0096] In this embodiment, a vehicle 4 including the sealing strip 1 in any of the above embodiments is defined. Therefore, the vehicle 4 has the advantages of the sealing strip 1 in any of the above embodiments and can achieve the technical effects that the sealing strip 1 in any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0097] Based on this, the vehicle 4 includes a body and a tailgate. The body corresponds to the first structure 2 in the aforementioned embodiment, and the tailgate corresponds to the second structure 3 in the aforementioned embodiment. The sealing strip 1 is installed on the body through the body 11. The non-Newtonian fluid layer 12 is arranged at least on the side of the body 11 facing the tailgate. When the tailgate is closed, the non-Newtonian fluid layer 12 replaces the body 11 in contact with the tailgate and fills the gap between the tailgate and the body 11 with its soft texture to meet the sealing requirements.

[0098] When the tailgate vibrates due to vehicle bumps, the stiffness of the non-Newtonian fluid increases due to the impact, thereby absorbing some of the impact energy and providing effective support for the tailgate. This reduces the vibration amplitude of the tailgate and solves the technical problems in related technologies, such as the easy generation of primary sound pressure waves inside the vehicle body, causing discomfort such as ear fullness for users inside the vehicle, and poor vehicle comfort.

[0099] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
