Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and in particular to a connector.

[0002] The present invention also relates to a trim strip assembly including the above-described connector, and a vehicle including the above-described connector. Background Technology

[0003] Currently, the connection between the two trim strips on the vehicle body is achieved through a plug-in connection. Specifically, a connector is inserted into one trim strip, and then the connector for the other trim strip is plugged in to connect the two trim strips. However, this connection method tends to result in a large gap and surface difference between the two trim strips after assembly. Summary of the Invention

[0004] Embodiments of this application provide a connector and a vehicle that can reduce the assembly difficulty when connecting two trim strips and reduce the gap and surface difference between the two trim strips.

[0005] In a first aspect, this application can provide a connector for connecting between a first decorative strip and a second decorative strip, wherein the first decorative strip includes a first end face and a first receiving groove, and the second decorative strip includes a second end face and a second receiving groove, wherein the second end face contacts the first end face, and the second receiving groove communicates with the first receiving groove;

[0006] The connector is located within the first receiving groove and the second receiving groove. One end of the connector is connected to the first decorative strip, and the other end of the connector is connected to the second decorative strip. The connector can restrict the movement of the first decorative strip relative to the second decorative strip along a first direction, a second direction, and a third direction, and / or, the connector can restrict the movement of the second decorative strip relative to the first decorative strip along a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are arranged perpendicularly to each other, and the first direction is the mating direction between the first end face and the second end face.

[0007] Understandably, the existing method of connecting two trim strips is a plug-in connection, which involves inserting a connector into one trim strip and then plugging the connector of the trim strip onto the other trim strip to achieve the connection between the two trim strips. However, this connection method is prone to causing large gaps and surface differences at the connection point of the two trim strips after assembly.

[0008] Therefore, in the technical solution of this application, by setting a connector and placing the connector in the first receiving groove of the first decorative strip and the second receiving groove of the second decorative strip, the first decorative strip and the second decorative strip can cooperate to receive the connector by fixing the two ends of the connector to the first decorative strip and the second decorative strip respectively, and the connector can achieve the docking of the first end face of the first decorative strip and the second end face of the second decorative strip.

[0009] Furthermore, because the connector can restrict the movement of the two decorative strips along the first, second, and third directions, it can limit the movement of the two decorative strips in different directions (up and down, third direction, left and right, first direction, front and back, second direction) after the two decorative strips are connected. This ensures that after the first end face of the first decorative strip and the second end face of the second decorative strip come into contact with each other, the connector's fixed position will prevent one from shifting, tilting, or being offset relative to the other. This facilitates a better mating and matching of the first end face of the first decorative strip and the second end face of the second decorative strip, reduces the gap and surface difference at the connection between the first and second decorative strips, and achieves a good aesthetic effect.

[0010] In one possible implementation, the first decorative strip further includes a first side surface connected to the first end face, and the first side surface is provided with a first stop groove, which communicates with the first receiving groove.

[0011] The connector includes a body and a first limiting structure. The body includes a first end and a second end. The first end is located in the first receiving groove, and the second end is located in the second receiving groove. The first end includes a first peripheral side. The first limiting structure protrudes from the first peripheral side. At least a portion of the first limiting structure is located in the first stop groove and abuts against the groove wall of the first stop groove to restrict the movement of the first decorative strip relative to the second decorative strip along the first direction.

[0012] In one possible implementation, the first limiting structure includes a guide surface and a contact surface connected together, the guide surface and the contact surface being arranged at an angle, at least a portion of the guide surface being located within the first receiving groove, and the contact surface abutting against the groove wall of the first stop groove.

[0013] In one possible implementation, the first limiting structure includes a main body and a buffer structure. The main body is connected to the first peripheral side and is located in the first receiving groove and the first stop groove. The buffer structure is connected to the main body and abuts against the groove wall of the first stop groove. The buffer structure has a hollow area between itself and the main body.

[0014] In one possible implementation, the first limiting structure includes a main body and a buffer structure. The main body is connected to the first peripheral side and is located in the first receiving groove and the first stop groove. The buffer structure is connected to the main body and abuts against the groove wall of the first stop groove. The buffer structure is serrated.

[0015] In one possible implementation, the wall of the first receiving groove is provided with a retaining member, and the connector further includes a second limiting structure. The second limiting structure is disposed on the first peripheral side and spaced apart from the first limiting structure. The second limiting structure engages with the retaining member to restrict the movement of the first decorative strip relative to the second decorative strip in the second direction.

[0016] In one possible implementation, the connector further includes a first top surface and a third limiting structure. The first top surface is connected to both the first peripheral side surface and the first end surface. The first top surface faces the first decorative strip. The third limiting structure is disposed on the first top surface and abuts against the wall of the first receiving groove to restrict the movement of the first decorative strip relative to the second decorative strip in the third direction.

[0017] In one possible implementation, the surface of the third limiting structure that abuts against the wall of the first receiving groove is a plane or a curved surface.

[0018] In one possible implementation, the connector further includes a first bottom surface and at least one contact protrusion, the first bottom surface being disposed opposite to the first top surface, and at least one of the contact protrusions being connected to the first bottom surface, the contact protrusion being used to contact the vehicle body.

[0019] In one possible implementation, the second end includes a second top surface, which is bonded to the wall of the second receiving groove.

[0020] Secondly, this application also provides a decorative strip assembly, the decorative strip assembly including a first decorative strip, a second decorative strip and the aforementioned connector, the connector connecting the first decorative strip and the second decorative strip.

[0021] Thirdly, this application also provides a vehicle, the vehicle including a first decorative strip, a second decorative strip and the aforementioned connector, the connector connecting the first decorative strip and the second decorative strip. Attached Figure Description

[0040] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0041] And / or: This is simply a way of describing the relationship between related objects. It indicates that there can be three kinds of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0042] Multiple: refers to two or more.

[0043] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0044] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0045] This application provides a connector, a trim strip assembly, and a vehicle, which can reduce the assembly difficulty when connecting two trim strips and reduce the gap surface difference between the two trim strips.

[0046] Please see Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 200 provided in an embodiment of this application. The vehicle 200 may include a body 210 and a trim assembly 100, the trim assembly 100 being connected to the body 210. The trim assembly 100 may be a window trim strip, which can be installed around the window to serve decorative and windproof functions.

[0047] It should be noted that, Figure 1 The purpose of this illustration is merely to depict the connection relationship between the vehicle body 210 and the trim assembly 100, and it is not intended to specifically limit the connection positions, specific structures, or quantities of the various devices. Furthermore, the structures illustrated in this application's embodiments do not constitute a specific limitation on the vehicle 200. In other embodiments of this application, the vehicle 200 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0048] Please refer to the following: Figure 2 and Figure 3 , Figure 2 This is a partial structural schematic diagram of the decorative strip assembly 100 provided in an embodiment of this application. Figure 3 yes Figure 2 The diagram shows a bottom view of the decorative strip assembly 100. The decorative strip assembly 100 may include a first decorative strip 10, a second decorative strip 20, and a connector 30. The first decorative strip 10 and the second decorative strip 20 are joined together via the connector 30. The joining direction of the first decorative strip 10 and the second decorative strip 20 is a first direction X, the width direction of the first decorative strip 10 and the second decorative strip 20 is a second direction Y, and the thickness direction of the first decorative strip 10 and the second decorative strip 20 is a third direction Z. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0049] It should be noted that, Figure 2 The decorative strip assembly 100 shown is only a partial structural diagram of the joint between two decorative strips. Any structural improvements to the decorative strip assembly 100 can be applied to various locations on the vehicle 200 where window trim strips are provided and where two trim strips need to be joined, provided there are no conflicts.

[0050] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 2 The diagram shows a partial structural representation of the first decorative strip 10. The first decorative strip 10 has a first receiving groove 11, which can accommodate components such as the connector 30 and parts of the body 210. The first decorative strip 10 includes a first end face 12 and a first side face 13. The first end face 12 is the end face of the first decorative strip 10 that abuts with the second decorative strip 20, and the first side face 13 is connected to the first end face 12. The first side face 13 has a first stop groove 14, which communicates with the first receiving groove 11. That is, the first stop groove 14 is a through groove that can penetrate the side of the first decorative strip 10 and communicate with the first receiving groove 11 located within the first decorative strip 10.

[0051] Please refer to the following: Figure 3 and Figure 5 , Figure 5 yes Figure 2 The diagram shows a partial structural representation of the second decorative strip 20. The second decorative strip 20 has a second receiving groove 21, which can accommodate components such as the connector 30 and parts of the body 210. The second decorative strip 20 includes a second end face 22, which is the end face of the second decorative strip 20 that abuts with the first decorative strip 10. Specifically, the second end face 22 contacts the first end face 12, and the second receiving groove 21 communicates with the first receiving groove 11, thereby enabling the second decorative strip 20 and the first decorative strip 10 to be connected end-to-end.

[0052] The connector 30 is located in the first receiving groove 11 and the second receiving groove 21. One end of the connector 30 is connected to the first decorative strip 10, and the other end of the connector 30 is connected to the second decorative strip 20. The connector 30 can restrict the movement of the first decorative strip 10 relative to the second decorative strip 20 along the first direction X, the second direction Y, and the third direction Z, and / or, the connector 30 can restrict the movement of the second decorative strip 20 relative to the first decorative strip 10 along the first direction X, the second direction Y, and the third direction Z.

[0053] Understandably, the existing method of connecting two trim strips is a plug-in connection, which involves inserting a connector into one trim strip and then plugging the connector of the trim strip onto the other trim strip to achieve the connection between the two trim strips. However, this connection method is prone to causing large gaps and surface differences at the connection point of the two trim strips after assembly.

[0054] Therefore, in the technical solution of this application, by setting a connector 30 and placing the connector 30 in the first receiving groove 11 of the first decorative strip 10 and the second receiving groove 21 of the second decorative strip 20, the connector 30 can be fixed to the first decorative strip 10 and the second decorative strip 20 at both ends, thereby enabling the first decorative strip 10 and the second decorative strip 20 to cooperate in receiving the connector 30, and enabling the connector 30 to connect the first end face 12 of the first decorative strip 10 and the second end face 22 of the second decorative strip 20.

[0055] Furthermore, since the connector 30 can restrict the movement of the two decorative strips along the first direction X, the second direction Y, and the third direction Z, after the two decorative strips are connected, the connector 30 can restrict the movement of the two decorative strips in different directions such as up and down (third direction Z), left and right (first direction X), and front and back (second direction Y). This ensures that after the first end face 12 of the first decorative strip 10 and the second end face 22 of the second decorative strip 20 come into contact with each other, the connector 30 will fix them so that one of them does not shift, tilt, or offset relative to the other. This is beneficial for achieving a better mating match between the first end face 12 of the first decorative strip 10 and the second end face 22 of the second decorative strip 20, reducing the gap and surface difference at the connection between the first decorative strip 10 and the second decorative strip 20, and achieving a good appearance effect.

[0056] It should be noted that the connector 30 is not limited to being applied between the first decorative strip 10 and the second decorative strip 20; it can also be applied between any two components that need to achieve end face matching. The embodiments of this application do not impose strict limitations on this.

[0057] The principle by which the connector 30 can restrict the relative movement between the first decorative strip 10 and the second decorative strip 20 will be explained below in conjunction with the specific structure of the connector 30.

[0058] Please refer to the following: Figure 6 and Figure 7 , Figure 6 yes Figure 3 The diagram shows a structural schematic of an angle of a connector 30 of the decorative strip assembly 100. Figure 7 yes Figure 3 The diagram shows an assembly of the connector 30 and the second decorative strip 20 of the decorative strip assembly 100. The connector 30 may include a body 31, a first limiting structure 32, a second limiting structure 33, and a third limiting structure 34.

[0059] The main body 31 may include a first end 311 and a second end 312. The first end 311 is the end of the main body 31 that is connected to the first decorative strip 10, and the first end 311 is located within the first receiving groove 11. The first end 311 may include a first top surface 313, a first bottom surface 314, and a first peripheral side surface 315 connecting the first top surface 313 and the first bottom surface 314. The first top surface 313 and the first bottom surface 314 are arranged opposite to each other, with the first top surface 313 facing the first decorative strip 10 and the first bottom surface 314 facing the vehicle body 210. The second end 312 is the end of the main body 31 that is connected to the second decorative strip 20, and the second end 312 is located within the second receiving groove 21.

[0060] The first limiting structure 32 protrudes from the first peripheral side 315, and at least a portion of the first limiting structure 32 is located within the first stop groove 14 of the first decorative strip 10 and abuts against the groove wall of the first stop groove 14. With this configuration, the connector 30 can be secured to the first decorative strip 10 through the cooperation of the first limiting structure 32 and the first stop groove 14. The securing of the first limiting structure 32 and the first stop groove 14 restricts the movement of the first decorative strip 10 relative to the second decorative strip 20 along the first direction X, preventing lateral swaying between the first decorative strip 10 and the second decorative strip 20, and helping to reduce the gap and surface difference at the connection point of the first decorative strip 10 and the second decorative strip 20.

[0061] For one possible implementation, please refer to Figure 8 , Figure 8 yes Figure 3 The diagram shows a simplified structural representation of the first limiting structure 32 of the connector 30. The first limiting structure 32 may include a guide surface 321 and a contact surface 322 connected together. The guide surface 321 and the contact surface 322 are arranged at an angle. At least a portion of the guide surface 321 is located within the first receiving groove 11, and the contact surface 322 abuts against the wall of the first stop groove 14. That is, the guide surface 321 is an inclined surface, which provides guidance for the first limiting structure 32 as it extends into the first stop groove 14 and the first receiving groove 11, enabling it to slide quickly into the first stop groove 14 and the first receiving groove 11 with high reliability. When the first limiting structure 32 slides into place, the contact surface 322 abuts against the wall of the first stop groove 14, thereby holding the first limiting structure 32 against the first stop groove 14 and effectively limiting the movement of the first decorative strip 10 relative to the second decorative strip 20 along the first direction X.

[0062] For another possible implementation, please refer to Figure 9 , Figure 9 yes Figure 3The diagram shows another schematic representation of the first limiting structure 32 of the connector 30. The first limiting structure 32 may include a main body 323a and a buffer structure 324a. The main body 323a is connected to the first peripheral side 315 of the main body 31 and is located in the first receiving groove 11 and the first stop groove 14. The buffer structure 324a is connected to the main body 323a and abuts against the wall of the first stop groove 14. A hollow area 325 is formed between the buffer structure 324a and the main body 323a. In this configuration, by forming a hollow area 325 between the buffer structure 324a and the main body 323a, the buffer structure 324a abuts against the wall of the first stop groove 14 during the insertion of the first limiting structure 32 into the first stop groove 14 and the first receiving groove 11. This allows the buffer structure 324a to gradually move closer to the main body 323a, thus enabling the hollow area 325 to absorb the tolerances of the first decorative strip 10 and the second decorative strip 20 in the first direction X, resulting in good reliability.

[0063] For another possible implementation, please refer to Figure 10 , Figure 10 yes Figure 3 The diagram shows another schematic representation of the first limiting structure 32 of the connector 30. The first limiting structure 32 may include a main body 323b and a buffer structure 324b. The main body 323b is connected to the first peripheral side 315 of the main body 31 and is located in the first receiving groove 11 and the first stop groove 14. The buffer structure 324b is connected to the main body 323b and abuts against the groove wall of the first stop groove 14. The buffer structure 324b is serrated. In this configuration, by making the buffer structure 324b serrated, it can abut against the groove wall of the first stop groove 14 during the process of the first limiting structure 32 extending into the first stop groove 14 and the first receiving groove 11, and give the buffer structure 324b a compressive tendency. This allows the buffer structure 324b to absorb the tolerances of the first decorative strip 10 and the second decorative strip 20 in the first direction X, resulting in good reliability.

[0064] Please refer to the following: Figure 3 , Figure 6 and Figure 11 , Figure 11 It is along Figure 3The diagram shows a simplified cross-sectional view of the second limiting structure 33 of the connector 30 obtained by cutting along the sectional line AA. In the embodiments of this application, the groove wall of the first receiving groove 11 is provided with a retaining member 15, which has a receiving space 16 capable of accommodating part of the connector 30. For example, the retaining member 15 can be a claw. Specifically, the second limiting structure 33 is provided on the first peripheral side 315 and spaced apart from the first limiting structure 32. The retaining member 15 is located on the periphery of the body 31 and is engaged with the second limiting structure 33. Under this configuration, the connector 30 can be engaged and fixed with the first decorative strip 10 through the cooperation of the second limiting structure 33 and the retaining member 15. The engagement of the second limiting structure 33 and the retaining member 15 can restrict the movement of the first decorative strip 10 relative to the second decorative strip 20 along the second direction Y, preventing the first decorative strip 10 and the second decorative strip 20 from swaying back and forth, which helps to reduce the gap and surface difference at the connection between the first decorative strip 10 and the second decorative strip 20.

[0065] One possible implementation, such as Figure 6 As shown, the main body 31 is also provided with a through hole 316. The through hole 316 is located close to the second limiting structure 33 and can provide a certain deformation space for the second limiting structure 33.

[0066] For example, such as Figure 6 As shown, there are two second limiting structures 33, which are respectively disposed on two opposite surfaces of the first circumferential side 315, that is, the two second limiting structures 33 are spaced apart in the second direction Y. Furthermore, the orthographic projection of one second limiting structure 33 on the body 31 can fall within the orthographic projection range of the other second limiting structure 33 on the body 31. Alternatively, the orthographic projection of one second limiting structure 33 on the body 31 can be offset from the orthographic projection of the other second limiting structure 33 on the body 31, that is, the two second limiting structures 33 are offset in the first direction X. There are also two through holes 316, which are spaced apart, with each through hole 316 located close to one of the second limiting structures 33.

[0067] Please refer to the following: Figure 6 and Figure 12 , Figure 12 It is along Figure 3The diagram shows a simplified cross-sectional view of the third limiting structure 34 of the connector 30 obtained by sectioning along the cutting line BB. The third limiting structure 34 is located on the first top surface 313 and abuts against the wall of the first receiving groove 11. With this configuration, the connector 30 can restrict the movement of the first decorative strip 10 relative to the second decorative strip 20 along the third direction Z by the abutment between the third limiting structure 34 and the wall of the first receiving groove 11, thus preventing the first decorative strip 10 and the second decorative strip 20 from swaying up and down, which helps to reduce the gap and surface difference at the connection between the first decorative strip 10 and the second decorative strip 20.

[0068] For example, such as Figure 6 As shown, there are two third limiting structures 34, which are respectively located on opposite sides of the first top surface 313. That is, the two second limiting structures 33 are spaced apart in the first direction X.

[0069] In one possible implementation, the surface of the third limiting structure 34 that abuts against the wall of the first receiving groove 11 is a plane.

[0070] For another possible implementation, please refer to [reference needed]. Figure 12 and Figure 13 , Figure 13 It is along Figure 3 The diagram shows another schematic cross-sectional view of the third limiting structure 34 of the connector 30 obtained by sectioning along the cutting line BB shown. The surface of the third limiting structure 34 that abuts against the wall of the first receiving groove 11 is a curved surface. For example, the shape of the curved surface can be a Bézier curve, a spline curve, or an arc.

[0071] Please refer to the following: Figure 14 , Figure 15 and Figure 16 , Figure 14 yes Figure 3 The diagram shows a structural schematic of the contact protrusion 35 of the connector 30 at an angle. Figure 15 yes Figure 14 The diagram shows the assembly of the contact protrusion 35 of the connector 30 with the vehicle body 210. Figure 16 yes Figure 14 The diagram shows the state of the connector 30 when the contact protrusion 35 is not provided.

[0072] In embodiments of this application, the connector 30 may further include at least one contact protrusion 35, which is connected to the first bottom surface 314 of the first end 311. The contact protrusion 35 is used to contact the vehicle body 210. It is understood that the relationship between the connector 30 and the first decorative strip 10 and the second decorative strip 20 is that they are fastened together in the third direction Z, that is, the engagement relationship between the connector 30 and the first decorative strip 10 and the second decorative strip 20 is a top-to-bottom fastening. Thus, by providing the contact protrusion 35 on the first bottom surface 314 of the first end 311, the first decorative strip 10 can be fastened downward onto the connector 30, which can compress the retaining member 15 and cause the retaining member 15 to undergo elastic deformation. The connector 30 as a whole is under pressure and has a tendency to move towards the vehicle body 210, thereby causing the contact protrusion 35 to abut against the vehicle body 210. After the contact protrusion 35 abuts against the vehicle body 210, it can provide a reaction force for the second limiting structure 33 to hold the retaining member 15.

[0073] During the process of the first decorative strip 10 being snapped down onto the connector 30, the third limiting structure 34 will also be pressed by the first decorative strip 10 and come into close contact with the groove wall of the first receiving groove 11. During this process, the third limiting structure 34 undergoes elastic deformation, thereby absorbing the assembly tolerance between the first decorative strip 10 and the connector 30, and ensuring that the second limiting structure 33 can be more easily snapped into the holding member 15.

[0074] In addition, since the contact protrusion 35 is designed as a protrusion, the direct contact area between the connector 30 and the sheet metal of the body 210 is reduced, which can reduce the precision requirements of the connector 190 in manufacturing (such as the precision of matching with the sheet metal of the body 210), so as to absorb the manufacturing tolerance and assembly tolerance, and further make it easier for the second limiting structure 33 to be inserted into the holding member 15.

[0075] If the contact protrusion 35 is not provided during this process, such as Figure 16 As shown, this will cause the first bottom surface 314 of the first end 311 to directly contact the body 210, thereby deforming the connecting piece 30 and preventing the second limiting structure 33 from engaging with the retaining piece 15. Furthermore, due to the tolerances of the body 210 sheet metal, the connecting piece 30 will deform as a whole, leading to larger tolerances, which can easily cause abnormal noises and lower reliability.

[0076] In one possible implementation, please refer again. Figure 6 The second end 312 may include a second top surface 317, which is bonded to the wall of the second receiving groove 21, thereby fixing the second end 312 to the second decorative strip 20, and further fixing the connector 30 to the second decorative strip 20. In this embodiment, as...
