Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] The following description, with reference to the accompanying drawings, describes the door sealing strip corner insert 10 according to an embodiment of the present invention.

[0049] like Figure 1 and Figure 4 As shown, the door sealing strip corner insert 10 according to an embodiment of the present invention includes a body 1 and a buckle 2.

[0050] Specifically, see the attached document. Figure 1 Appendix Figure 2 and attached Figure 3As shown, the buckle 2 and the body 1 are separate processed parts and detachably connected. The buckle 2 and the body 1 can be manufactured separately, reducing the molding difficulty of the buckle 2 and the body 1, and lowering the mold complexity of the door sealing strip corner insert 10. This facilitates the production and processing of the door sealing strip corner insert 10. Furthermore, if one of the buckle 2 or the body 1 is damaged, only the damaged buckle 2 or the body 1 needs to be replaced, without replacing the entire door sealing strip corner insert 10. This relatively reduces the cost of the door sealing strip corner insert 10, allows for the sharing of the buckle 2, and improves the consistency and compatibility of the door sealing strip corner insert 10. At the same time, by processing the buckle 2 and the body 1 separately, different materials can be selected for different requirements of the buckle 2 and the body 1, achieving differentiation between the body 1 and the buckle 2, meeting the toughness and strength requirements of the door sealing strip corner insert 10, and improving the finished product qualification rate of the door sealing strip corner insert 10.

[0051] It is understandable that if Figure 5 As shown, the door sealing strip corner insert 10 of this utility model is used for the door sealing strip 100. The door sealing strip 100 has a corner portion 3, and the body 1 is embedded in the corner portion 3. At least part of the buckle 2 extends out of the corner portion 3 to be snapped and connected with the inner panel 200 of the door. By processing the buckle 2 and the body 1 separately, the buckle 2 and the body 1 can be made of different materials. This can ensure the toughness of the buckle 2 and prevent the buckle 2 from breaking during assembly, and also ensure the support strength of the body 1 and prevent the corner portion 3 from shaking or collapsing.

[0052] According to the embodiment of this utility model, the door sealing strip corner insert 10 is made by means of a snap fastener 2 and a body 1, which are separate processed parts and detachably connected. This allows the snap fastener 2 and the body 1 to be manufactured separately, reducing the molding difficulty of the snap fastener 2 and the body 1, lowering the mold complexity of the door sealing strip corner insert 10, and facilitating its production. Furthermore, if one of the snap fastener 2 or the body 1 is damaged, only the damaged snap fastener 2 or the body 1 needs to be replaced, without replacing the entire door sealing strip corner insert 10. This relatively reduces the cost of the door sealing strip corner insert 10, allows for the sharing of the snap fastener 2, and improves the consistency and compatibility of the door sealing strip corner insert 10. At the same time, by processing the snap fastener 2 and the body 1 separately, different materials can be selected for different requirements of the snap fastener 2 and the body 1, achieving differentiation between the body 1 and the snap fastener 2, meeting the toughness and strength requirements of the door sealing strip corner insert 10, and improving the finished product qualification rate of the door sealing strip corner insert 10.

[0053] In some embodiments of this utility model, reference is made to the appendix. Figure 1As shown, the buckle 2 is snapped into the body 1. The snapping operation is simple and quick, which can reduce the assembly difficulty of the buckle 2 and the body 1, shorten the assembly time of the buckle 2 and the body 1, improve the assembly efficiency of the door sealing strip corner insert 10, and ensure the reliability and stability of the door sealing strip corner insert 10.

[0054] In some embodiments of this utility model, reference is made to the appendix. Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the body 1 has a locking hole 11, and the buckle 2 includes a fixing part 21 and a locking part 22. The locking part 22 is located in the thickness direction of the body 1 (see attached figure). Figure 1 On one side (direction a) shown, the fixing part 21 passes through the card hole 11 and is connected to the body 1. The fixing part 21 is used to fix the body 1 to ensure the connection between the buckle 2 and the body 1, thereby fixing the locking part 22 and ensuring the locking part 22 is connected to the inner panel 200 of the door.

[0055] Specifically, see the attached document. Figure 3 and attached Figure 4 As shown, the snap-fit ​​part 22 includes a fixing plate 221 and two spring arms 222. The fixing plate 221 is connected to the fixing part 21. The two spring arms 222 are located on opposite sides of the fixing plate 221. The fixed ends of the two spring arms 222 are connected to the end of the fixing plate 221 away from the fixing part 21. The free ends of the two spring arms 222 extend in the direction away from each other.

[0056] In a further embodiment of this utility model, reference is made to the appendix. Figure 4 As shown, in conjunction with the reference appendix Figure 2 and attached Figure 3 The inner wall of the card hole 11 is provided with a limiting protrusion 111, and the outer peripheral wall of the fixing part 21 is provided with a limiting groove 211. The limiting protrusion 111 is engaged in the limiting groove 211. Through the cooperation of the limiting protrusion 111 and the limiting groove 211, the fixing part 21 can be limited, preventing the fixing part 21 from continuing to move towards the limiting protrusion 111, thereby ensuring the positioning accuracy of the buckle 2 and ensuring the connection between the buckle 2 and the inner panel 200 of the door.

[0057] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, along the length of the slot 11 (see attached diagram) Figure 2As shown in direction b), the locking hole 11 includes a first region 112 and a second region 113. The first region 112 and the second region 113 are arranged and connected along the length of the locking hole 11. A limiting protrusion 111 is provided in the first region 112 and extends along the circumferential direction of the locking hole 11. A limiting groove 211 extends along the circumferential direction of the fixing part 21. The fixing part 21 is configured to pass through the second region 113 into the locking hole 11 and move toward the first region 112 to engage with the body 1. Since there is no limiting protrusion 111 in the second region 113, the fixing part 21 can be inserted into the second region 113. After the fixing part 21 is inserted into the second region 113, it moves towards the first region 112. Since there is a limiting protrusion 111 in the first region 112, the limiting groove 211 of the fixing part 21 cooperates with the limiting protrusion 111 to prevent the fixing part 21 from coming out of the card hole 11, thereby fixing the snap-fit ​​part 22 to the body 1, thus ensuring the positioning accuracy of the buckle 2 and ensuring the connection between the buckle 2 and the inner panel 200 of the door.

[0058] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the two ends of the limiting groove 211 in the length direction are provided with stop portions 212. The two stop portions 212 are respectively used to abut against the two ends of the limiting protrusion 111 in the length direction. By abutting against the limiting protrusion 111, the stopping portions 212 can limit the fixing portion 21 and prevent the fixing portion 21 from continuing to move away from the second area 113, thereby ensuring the positioning accuracy of the buckle 2 and ensuring the connection between the buckle 2 and the inner panel 200 of the door. In addition, the two stop portions 212 abut against the two ends of the limiting protrusion 111 in the length direction, which can prevent the fixing portion 21 from rotating in the first area 112, further ensuring the reliability of the connection between the buckle 2 and the body 1 and improving the stability of the door sealing strip corner insert 10.

[0059] In some embodiments of this utility model, the buckle 2 has greater toughness than the body 1, which can ensure the reliability and stability of the buckle 2, prevent the buckle 2 from breaking during assembly, reduce the replacement time caused by the buckle 2 breaking during assembly, avoid affecting the vehicle assembly efficiency, extend the service life of the buckle 2, improve the part qualification rate, and thus ensure the connection reliability between the door sealing strip 100 and the inner door panel 200.

[0060] Furthermore, the strength of the body 1 is higher than that of the buckle 2, which can ensure the support strength of the door sealing strip corner insert 10, prevent the corner part 3 of the door sealing strip 100 from shaking, prevent the door sealing strip 100 from collapsing, improve the straightness of the door sealing strip 100, and thus improve the appearance flatness of the door sealing strip 100. This avoids the need to repeatedly adjust the door sealing strip 100 due to the weak support of the door sealing strip corner insert 10, relatively shortens the assembly time of the door sealing strip 100, and improves the assembly efficiency of the door sealing strip 100.

[0061] In the prior art, when PA66 is used for the corner insert of the door sealing strip, the toughness of the corner insert meets the requirements, but the strength is low, resulting in poor support strength after installation, causing the corner to collapse easily and resulting in poor straightness. When PA66+GF30 is used for the corner insert of the door sealing strip, the corner insert can meet the requirements of toughness and strength, but the whole is prone to dehydration under high temperature, which makes it easy to break during assembly.

[0062] In a specific example, the clip 2 is made of PA66 (polyamide 66, also known as nylon 66), which has high mechanical strength and good toughness, ensuring the reliability and stability of the clip 2, preventing brittle breakage, reducing replacement time due to clip 2 breakage during assembly, avoiding impact on vehicle assembly efficiency, extending the service life of the clip 2, and improving the part qualification rate, thereby ensuring the reliable connection between the door sealing strip 100 and the door inner panel 200; the body 1 is made of PA66+GF30 (polyamide 66 (PA66) plastic raw material with 30% added) The glass fiber (GF) composite material component has high strength and rigidity, which can ensure the support strength of the corner insert 10 of the door sealing strip, prevent the corner 3 of the door sealing strip 100 from shaking, prevent the door sealing strip 100 from collapsing, improve the straightness of the door sealing strip 100, and thus improve the appearance flatness of the door sealing strip 100. It also avoids the need for repeated adjustments of the door sealing strip 100 due to the weak support of the corner insert 10, thus shortening the assembly time of the door sealing strip 100 and improving the assembly efficiency of the door sealing strip 100.

[0063] This utility model also proposes a door sealing strip 100 having the door sealing strip corner insert 10 of the above embodiment.

[0064] like Figure 5 As shown, the door sealing strip 100 according to an embodiment of the present utility model includes a sealing strip body 20 and the aforementioned door sealing strip corner insert 10.

[0065] Specifically, see the attached document. Figure 5 As shown, the sealing strip body 20 has a corner portion 3, which is located at the corner of the inner door panel 200. This corner portion 3 can cover up defects in the inner door panel 200. The body 1 is embedded in the corner portion 3, and at least a portion of the buckle 2 extends out of the corner portion 3. The snap-fit ​​portion 22 of the buckle 2 can extend from the corner portion 3 and snap-fit ​​with the inner door panel 200 to fix the door sealing strip 100 to the inner door panel 200, thereby improving the static sealing after the vehicle is closed and the flushness of the corner.

[0066] Further, see attached document. Figure 5As shown, the sealing strip body 20 also includes a first sealing strip 4 and a second sealing strip 5. Both the first sealing strip 4 and the second sealing strip 5 are extruded and precision-cut by an extrusion section. The first sealing strip 4 and the second sealing strip 5 are respectively snapped onto the adjacent two sides of the inner door panel 200. The first sealing strip 4 and the second sealing strip 5 extend along the adjacent two sides of the inner door panel 200 and are both connected to the corner portion 3. Both the first sealing strip 4 and the second sealing strip 5 have guide groove features. The inner door panel 200 is provided with a guide rail structure. Through the cooperation of the guide rail and the guide groove, the first sealing strip 4 and the inner door panel 200, and the second sealing strip 5 and the inner door panel 200 can be snapped together.

[0067] Specifically, both the first sealing strip 4 and the second sealing strip 5 are made of EPDM sponge (ethylene-propylene-diene copolymer sponge). EPDM sponge is a porous synthetic rubber material with excellent weather resistance, corrosion resistance, elasticity, and elastic recovery. It can resist ultraviolet radiation, oxidation, and climate change, and is not easily corroded by acids, alkalis, solvents, and chemicals. It also has good thermal insulation, heat insulation, cushioning, shock absorption, sound absorption, sound insulation, and sealing properties, which can ensure the reliability and stability of the first sealing strip 4 and the second sealing strip 5, and improve the sealing effect, sound insulation effect, and shock absorption effect of the door sealing strip 100.

[0068] The corner joint 3 is made of EPDM joint adhesive. EPDM joint adhesive usually refers to rubber joints made of EPDM rubber (ethylene propylene rubber), also known as flexible rubber soft joints. It has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance and other properties. It can resist the erosion of the inner wall of the rubber joint by corrosive media, effectively extend the service life of the equipment. It also has the characteristics of small size, light weight, good elasticity, good sealing, and convenient installation, maintenance and replacement. It can ensure the sealing of the corner joint 3, improve the sealing effect of the door sealing strip 100, and is conducive to the lightweight design of the vehicle.

[0069] Understandably, during the production and processing of the door sealing strip 100, the first sealing strip 4 and the second sealing strip 5 are first extruded to a suitable length by an extruder, and the ends are cut off by punching. Then, the first sealing strip 4 and the second sealing strip 5 are inserted into the mold by molding. The assembled door sealing strip corner insert 10 is then placed into the mold, and the corner part 3 is formed by molding to create a complete door sealing strip 100.

[0070] Furthermore, see the attached document. Figure 5As shown, the sealing strip body 20 is also provided with a second buckle 6, which is spaced apart from the buckle 2. This allows the door sealing strip 100 to be connected to the inner door panel 200 from two separate points, improving the reliability and stability of the door sealing strip 100's fixation. By using the buckles 2 and 6 to engage the door sealing strip 100 with the inner door panel 200 from two separate points, and with both the first sealing strip 4 and the second sealing strip 5 secured to the inner door panel 200, the sealing strip provides waterproofing, dustproofing, and sealing effects, and also provides some shock absorption. Preferably, the second buckle 6 is made of PA66 (polyamide 66, also known as nylon 66), which has high mechanical strength and good toughness, ensuring the reliability and stability of the second buckle 6, preventing brittle breakage, and extending its service life, thereby ensuring the reliable connection between the door sealing strip 100 and the inner door panel 200.

[0071] According to the embodiment of this utility model, the door sealing strip 100, by providing the aforementioned door sealing strip corner insert 10, and by having the buckle 2 and the body 1 as separate processed parts that are detachably connected, allows the buckle 2 and the body 1 to be manufactured separately. This reduces the molding difficulty of the buckle 2 and the body 1, reduces the mold complexity of the door sealing strip corner insert 10, and facilitates the production and processing of the door sealing strip corner insert 10. Furthermore, if one of the buckle 2 and the body 1 is damaged, only the damaged buckle 2 or the body 1 needs to be replaced, without replacing the entire door sealing strip corner insert 10. This relatively reduces the cost of the door sealing strip corner insert 10, allows for the sharing of the buckle 2, and improves the consistency and compatibility of the door sealing strip corner insert 10. At the same time, by processing the buckle 2 and the body 1 separately, different materials can be selected for different requirements of the buckle 2 and the body 1, achieving differentiation between the body 1 and the buckle 2, meeting the toughness and strength requirements of the door sealing strip corner insert 10, and improving the finished product qualification rate of the door sealing strip corner insert 10.

[0072] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, the body 1 is provided with a plurality of spaced-apart adhesive receiving holes 12. The adhesive receiving holes 12 penetrate the body 1 along the thickness direction of the body 1. The corner part 3 is a molded part. When processing the corner part 3, the door sealing strip corner insert 10 is placed into the mold. At this time, the corner part 3 also has a certain heating temperature and fluidity. The material of the corner part 3 can flow in through the adhesive receiving holes 12 and pass through the adhesive receiving holes 12. The material of the corner part 3 on one side of the thickness direction of the body 1 flows in through the adhesive receiving holes 12 and fuses with the material on the other side, so that the material of the corner part 3 completely covers the body 1, solving the problem of tight bonding between the body 1 and the corner part 3.

[0073] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 5 As shown, the main body 1 has multiple positioning protrusions 13 spaced apart, and the corner portion 3 has positioning holes 31 corresponding to the multiple positioning protrusions 13 one by one, so that the main body 1 and the corner portion 3 are positioned and fixed at corresponding positions. Since the main body 1 and the corner portion 3 may be made of different materials, when external forces are applied to the main body 1 and the corner portion 3 at the same time, the shrinkage rate or slight deformation of the main body 1 and the corner portion 3 to this force will be different due to the difference in their materials. The positioning protrusions 13 can prevent relative displacement between the main body 1 and the corner portion 3, thereby avoiding relative displacement between the main body 1 and the corner portion 3 after the force disappears and they return to their original shape, or preventing the cumulative relative displacement caused by repeated application of forces of different magnitudes from different directions from the corner portion 3, which may cause the main body 1 to break through the covering layer of the corner portion 3 and protrude from the corner portion 3.

[0074] This utility model also proposes a car door 1000 having the door sealing strip 100 of the above embodiment.

[0075] like Figure 6 , Figure 7 and Figure 8 As shown, the car door 1000 according to an embodiment of the present utility model includes an inner door panel 200 and the aforementioned door sealing strip 100.

[0076] Specifically, in conjunction with the reference appendix Figure 5 and attached Figure 7 As shown, both the sealing strip body 20 and the buckle 2 are snapped together with the inner door panel 200. The snapping operation is simple and quick, which can reduce the assembly difficulty of the sealing strip body 20 and the buckle 2 with the inner door panel 200, shorten the assembly time of the door sealing strip 100 with the inner door panel 200, improve the assembly efficiency of the door sealing strip 100, and ensure the reliability and stability of the door sealing strip 100.

[0077] According to the embodiment of the present utility model, the car door 1000, by providing the aforementioned car door sealing strip 100, and by having the buckle 2 and the body 1 as separate processed parts that are detachably connected, allows the buckle 2 and the body 1 to be manufactured separately. This reduces the molding difficulty of the buckle 2 and the body 1, reduces the mold complexity of the car door sealing strip corner insert 10, and facilitates the production and processing of the car door sealing strip corner insert 10. Furthermore, if one of the buckle 2 and the body 1 is damaged, only the damaged buckle 2 or the body 1 needs to be replaced, without replacing the entire car door sealing strip corner insert 10. This relatively reduces the cost of the car door sealing strip corner insert 10, allows for the sharing of the buckle 2, and improves the consistency and compatibility of the car door sealing strip corner insert 10. At the same time, by processing the buckle 2 and the body 1 separately, different materials can be selected for different requirements of the buckle 2 and the body 1, achieving differentiation between the body 1 and the buckle 2, meeting the toughness and strength requirements of the car door sealing strip corner insert 10, and improving the finished product qualification rate of the car door sealing strip corner insert 10.

[0079] According to the vehicle embodiment of this utility model, by providing the aforementioned door 1000, and by having the buckle 2 and body 1 as separate and detachably connected parts, the buckle 2 and body 1 can be manufactured separately. This reduces the molding difficulty of the buckle 2 and body 1, reduces the mold complexity of the door sealing strip corner insert 10, and facilitates the manufacturing process of the door sealing strip corner insert 10. Furthermore, if one of the buckle 2 and body 1 is damaged, only the damaged buckle 2 or body 1 needs to be replaced, without replacing the entire door sealing strip corner insert 10. This relatively reduces the cost of the door sealing strip corner insert 10, allows for the sharing of the buckle 2, and improves the consistency and compatibility of the door sealing strip corner insert 10. At the same time, by processing the buckle 2 and body 1 separately, different materials can be selected for different requirements of the buckle 2 and body 1, achieving differentiation between the body 1 and buckle 2, meeting the toughness and strength requirements of the door sealing strip corner insert 10, and improving the finished product qualification rate of the door sealing strip corner insert 10.
