Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a sealing strip for the side of an automobile front door. Background Art

[0002] Sealing strips are a type of material that can reduce shock, provide waterproofing, and insulate sound. There are many types of sealing strips, including metal, rubber, and plastic. Most of the sealing strips used in cars are made of rubber. Cars are equipped with sealing strips at the connection between the door and the frame to prevent wind from entering the car from the connection between the door and the frame during driving, causing abnormal noise, and to prevent the interior of the vehicle from being eroded by rain. However, existing sealing strips do not have waterproof measures at the connection between the sealing strip and the vehicle, which will cause rainwater to erode the connection, causing the connection to rust, thereby causing breakage, and the sealing strip's self-resetting effect is poor.

[0003] To address the above problems, a flame-retardant automobile front door side sealing strip as disclosed in the prior art patent application number CN202021310798.7 can be used. It uses a guide groove. When the car door is opened on a rainy day, rainwater falls on the surface of the sealing strip and can slide down through the guide groove, thereby preventing the sealing strip from being soaked by rainwater. At the same time, the spring reset drives the sealing strip to return to its original state, thereby improving the service life of the sealing strip.

[0004] However, in the above method, only using a spring for reset may easily cause deformation due to long-term use, and can only be used for sealing, but the sound insulation effect is insufficient. Utility Model Content

[0005] The purpose of the utility model is to provide a sealing strip for the side of a car front door, aiming to solve the technical problems in the prior art that only a spring is used for reset, which is prone to deformation due to long-term use, and can only perform sealing but has insufficient sound insulation effect.

[0006] To achieve the above-mentioned purpose, the utility model adopts a front door side sealing strip of an automobile, including a clamping assembly, a sealing assembly and a supporting member, the sealing assembly including multiple sets of reset units and sealing gaskets, the reset unit including a sliding member, a support rod, a connecting block, a support block and a memory alloy spring, the supporting member is arranged on the clamping assembly, the clamping member has a sliding groove, the sliding member is slidably connected to the sliding groove, the sealing gasket has a plurality of first through holes and a plurality of second through holes, the supporting block is fixedly connected to the sealing gasket, one end of the connecting block is hinged to the support block, and the other end of the connecting block passes through the corresponding first through hole, the sliding member has a supporting groove, one end of the support rod is fixedly connected to the connecting block, and the other end of the support rod is placed in the supporting groove, and the two ends of the memory alloy spring are respectively fixedly connected to the sliding member and the clamping assembly, and placed in the sliding groove.

[0007] The clamping assembly is provided with a filling port, a flow cavity and a plurality of outflow ports, and the filling port and the plurality of outflow ports are all connected to the flow cavity.

[0008] Wherein, the supporting member includes a plurality of elastic sheets and a plurality of clamping strips, the plurality of elastic sheets are fixedly connected to the clamping assembly, and the plurality of clamping strips are respectively arranged on the corresponding elastic sheets.

[0009] Wherein, the sliding member includes a slider and a force-bearing block, the slider is slidably connected to the sliding groove, the force-bearing block is fixedly connected to the slider, and the supporting groove is arranged on the force-bearing block.

[0010] Among them, the sealing gasket includes a connecting piece, a core layer, a sound insulation layer and a weather-resistant layer. The connecting piece is connected to the clamping assembly, the core layer is connected to the connecting piece, the sound insulation layer is arranged on the side of the core layer away from the connecting piece, and the weather-resistant layer is arranged on the side of the sound insulation layer away from the core layer.

[0011] Wherein, the clamping assembly includes a silicone layer and a pressing layer, the silicone layer is connected to the connecting piece, and the pressing layer is connected to the silicone layer.

[0012] Wherein, the sealing gasket is also provided with a guide groove.

[0013] Wherein, an air bag is also provided inside the sealing pad.

[0014] The utility model relates to a side sealing strip of a front door of an automobile. In specific use, the entire sealing strip is installed on the door frame through the clamping assembly. When the door is closed, the sealing strip is squeezed. At this time, the sealing strip drives the support block to move, and the support block drives one end of the connecting block to rotate on the support block, thereby driving the support rod to slide in the abutting groove. When the support rod slides in the abutting groove, since the sliding member is limited by the slide groove, the sliding member can only slide in the slide groove, thereby driving the memory alloy spring to complete the sealing of the closed door. Conversely, when the door is opened, the memory alloy spring resets and drives the sealing strip to reset, thereby making the The sealing strip returns to its original shape. This method can improve stability on the one hand, and on the other hand, the memory alloy spring is used as a supporting structure, which can automatically adjust its shape according to the frequency and force of door opening and closing, ensuring that the sealing strip and the door frame are closely fitted for a long time and reducing deformation caused by long-term use. At the same time, a highly elastic thermoplastic polyurethane (TPU) material is used as the core layer, which has excellent elastic recovery and wear resistance, ensuring that the sealing strip can still maintain a good shape and sealing effect after long-term use. On the basis of the TPU core layer, a layer of microporous sound insulation foam is embedded. This foam has high sound absorption and sound insulation properties, which can effectively isolate external noise and dust, and improve the quietness of the vehicle interior. At the same time, the outermost layer is made of highly weather-resistant polyvinyl chloride (PVC) material with UV resistance, aging resistance and weather resistance, extending the service life of the sealing strip. This method solves the technical problems of the existing technology that only uses springs for reset, which is prone to deformation due to long-term use and can only perform sealing but has insufficient sound insulation effect.

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] See also Figures 1 to 3 ,in Figure 1 This is a structural diagram of the automobile front door side sealing strip of the utility model. Figure 2 This is a cross-sectional view of the automobile front door side sealing strip of the utility model. Figure 3 This utility model Figure 2 A magnified view of the local structure at point A.

[0022] The utility model provides a sealing strip for the side of a front door of an automobile, comprising a clamping assembly, a sealing assembly and a supporting member, the sealing assembly comprising a plurality of reset units and sealing gaskets, the reset unit comprising a sliding member, a support rod 101, a connecting block 102, a supporting block 103 and a memory alloy spring 104, the supporting member comprising a plurality of elastic sheets 105 and a plurality of clamping strips 106, the sliding member comprising a slider 107 and a force-bearing block 108, the sealing gasket comprising a connecting member 109, a core layer 110, a sound insulation layer 111 and a weather-resistant layer 112, the clamping assembly comprising a silicone layer 113 and a pressing layer 114. The above-mentioned solution solves the technical problems in the prior art of only using springs for reset, which is prone to deformation due to long-term use, and can only perform sealing but has insufficient sound insulation effect.

[0023] According to this specific embodiment, the snap-on assembly is used to connect with the door frame to install the entire automobile front door side sealing strip.

[0024] Wherein, the abutment is provided on the clamping assembly, the clamping assembly has a slide groove 115, the sliding member is slidably connected to the slide groove 115, the sealing gasket has a plurality of first through holes 116 and a plurality of second through holes 117, the support block 103 is fixedly connected to the sealing gasket, one end of the connecting block 102 is hinged to the support block 103, the other end of the connecting block 102 passes through the corresponding first through hole 116, the sliding member has a supporting groove 118, one end of the support rod 101 is fixedly connected to the connecting block 102, and the other end of the support rod 101 is placed in the supporting groove 118, and both ends of the memory alloy spring 104 are fixedly connected to the sliding member and the clamping assembly, and are placed in the slide groove 115;

[0025] The connecting member 109 is connected to the clamping assembly, the core layer 110 is connected to the connecting member 109, the sound insulation layer 111 is arranged on a side of the core layer 110 away from the connecting member 109, and the weather-resistant layer 112 is arranged on a side of the sound insulation layer 111 away from the core layer 110;

[0026] During specific use, the entire sealing strip is installed on the door frame through the clamping assembly. When the door is closed, the sealing strip is squeezed. At this time, the sealing strip drives the support block 103 to move, and the support block 103 drives one end of the connecting block 102 to rotate on the support block 103, thereby driving the support rod 101 to slide in the abutting groove 118. When the support rod 101 slides in the abutting groove 118, since the sliding member is limited by the slide groove 115, the sliding member will only slide in the slide groove 115, thereby driving the memory alloy spring 104 to complete the sealing of the closed door. On the contrary, when the door is opened, the memory alloy spring 104 resets and drives the sealing strip to reset, thereby completing the sealing of the closed door. The sealing strip returns to its original shape. This approach improves stability. Furthermore, the memory alloy spring 104 serves as a support structure, automatically adjusting its shape based on the frequency and force of the door opening and closing, ensuring a long-term, tight fit between the sealing strip and the door frame and reducing deformation caused by long-term use. The core layer 110 is made of highly elastic thermoplastic polyurethane (TPU) material, which exhibits excellent elastic recovery and wear resistance, ensuring the sealing strip maintains its shape and sealing effect even after long-term use. Embedded within the TPU core layer 110 is a layer of microporous sound-insulating foam, which offers high sound absorption and insulation properties, effectively isolating external noise and dust, enhancing interior quietness. The outermost layer is made of highly weather-resistant polyvinyl chloride (PVC), offering UV resistance, aging resistance, and weather resistance, extending the service life of the sealing strip. This approach addresses the technical issues of existing technologies that rely solely on springs for return, which can easily cause deformation due to long-term use and only provide sealing without sufficient sound insulation.

[0027] Secondly, the snap-on assembly has a filling port 119, a flow cavity 120 and a plurality of flow outlets 121. The filling port 119 and the plurality of flow outlets 121 are all connected to the flow cavity 120. After the snap-on assembly is clamped on the door frame, sealant is injected through the filling port 119, so that the sealant enters the flow cavity 120, passes through the plurality of flow outlets 121 and flows between the snap-on assembly and the door frame, thereby improving the sealing effect.

[0028] At the same time, several of the elastic sheets 105 are fixedly connected to the snap-in assembly, and several of the holding strips 106 are respectively arranged on the corresponding elastic sheets 105. Multiple elastic sheets 105 are pressed against the door frame to fix the snap-in assembly, and the holding strips 106 improve the fixing effect.

[0029] In addition, the slider 107 is slidably connected to the slide groove 115, the force block 108 is fixedly connected to the slider 107, and the supporting groove 118 is set on the force block 108. The movement of the support rod 101 drives the force block 108 to move, and the force block 108 drives the slider 107 to slide in the slide groove 115.

[0030] Again, the silicone layer 113 is connected to the connecting member 109 , and the pressing layer 114 is connected to the silicone layer 113 . The silicone layer 113 can enhance the supporting effect.

[0031] Finally, the sealing gasket is also provided with a guide groove 122, and the sealing gasket is also provided with an air bag 123 inside. The guide groove 122 is used to guide rainwater, and the air bag 123 can absorb the heat on the surface of the sealing strip in hot weather, thereby reducing the temperature of the surface of the sealing strip and preventing the sealing strip from melting.

[0032] When the utility model is used, the side sealing strip of the front door of an automobile is installed on the door frame through the clamping assembly. When the door is closed, the sealing strip is squeezed. At this time, the sealing strip drives the support block 103 to move. The support block 103 drives one end of the connecting block 102 to rotate on the support block 103, thereby driving the support rod 101 to slide in the abutting groove 118. When the support rod 101 slides in the abutting groove 118, since the sliding member is limited by the slide groove 115, the sliding member will only slide in the slide groove 115, thereby driving the memory alloy spring 104 to complete the sealing of the closed door. On the contrary, when the door is opened, the memory alloy spring 104 resets the belt The sealing strip is reset, thereby returning it to its original shape. This approach improves stability. Furthermore, the memory alloy spring 104 serves as a support structure, automatically adjusting its shape based on the frequency and force of the door opening and closing, ensuring a long-term, close fit between the sealing strip and the door frame and reducing deformation caused by long-term use. The core layer 110 is constructed of a highly elastic thermoplastic polyurethane (TPU) material with excellent elastic recovery and wear resistance, ensuring the sealing strip maintains its shape and sealing effect even after long-term use. Embedded within the TPU core layer 110 is a layer of microporous sound-insulating foam, which offers high sound absorption and sound insulation properties, effectively isolating external noise and dust, enhancing interior quietness. The outermost layer is constructed of highly weather-resistant polyvinyl chloride (PVC), offering UV resistance, aging resistance, and weather resistance, extending the service life of the sealing strip. This approach addresses the technical issues of existing technologies that rely solely on springs for reset, which can easily cause deformation due to long-term use and only provide sealing without sufficient sound insulation.

[0033] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
