Detailed Implementation

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In related technologies, such as Figure 1 As shown, a decorative piece 5' is installed on the side of the door 6' located outside the passenger compartment, near the waistline, to enhance the overall aesthetics of the vehicle. The decorative piece 5' and the door 6' are not easily fixed at their ends along the length of the vehicle body; the ends of the decorative piece 5' ( Figure 1 The area marked by the dotted square in the middle tends to lift upwards in the height direction of the vehicle body, resulting in a large gap between the end of the door 6' and the trim piece 5', which affects the overall aesthetics of the vehicle. At the same time, debris can easily enter the gap between the door 6' and the trim piece 5, causing abnormal noises during vehicle operation, and the trim piece 5' is prone to falling off.

[0043] See Figure 2 , Figure 3 and Figure 4An embodiment of this application provides a connector for connecting a vehicle door 6 and a trim piece 5. The connector includes a main body 1, a first connecting portion 2, a second connecting portion 3, and a third connecting portion 4. The main body 1 serves as a mounting carrier, connecting the first connecting portion 2, the second connecting portion 3, and the third connecting portion 4. Specifically, the first connecting portion 2 is connected to the main body 1 and is located on one side of the main body 1 in a first direction, for connecting to the end of the trim piece 5. The second connecting portion 3 and the third connecting portion 4 are both connected to the main body 1 and are both used to connect to the vehicle door 6. The second connecting portion 3 is located on the side of the main body 1 facing away from the first connecting portion in the first direction, and the second connecting portion 3 can restrict the movement of the trim piece 5 relative to the vehicle door 6 in the first direction. The third connecting portion 4 cooperates with the second connecting portion 3 to restrict the movement of the trim piece 5 in a second direction, where the first and second directions intersect.

[0044] When installing the trim piece 5 to the door 6, connectors are first pre-installed at both ends of the trim piece 5. Specifically, the connectors are connected to the trim piece 5 via the first connecting part 2. Then, the connectors and trim piece 5 are assembled together with the door 6. Since the second connecting part 3 and the third connecting part 4 restrict the movement of the connector and the door 6 in the second direction, the second connecting part 3 and the third connecting part 4 cooperate to restrict the movement of the trim piece 5 in the second direction. After the trim piece 5 is connected to the door 6, the position of the trim piece 5 and the door 6 is relatively fixed, which can prevent the end of the trim piece 5 from sticking up, improve the overall aesthetics of the vehicle, reduce the possibility of foreign objects entering the gap between the trim piece 5 and the door 6, and reduce the risk of abnormal noise and trim piece 5 falling off during vehicle operation.

[0045] It should be noted that the first direction is the width direction of the connector (X-axis direction in the figure), the second direction is the height direction of the connector (Y-axis direction in the figure), and the third direction is the length direction of the connector (Z-axis direction in the figure). The first direction, the second direction, and the third direction intersect each other. When the connector is installed on the door 6, the first direction is parallel to the width direction of the vehicle body, the second direction is parallel to the height direction of the vehicle body, and the third direction is parallel to the length direction of the vehicle body.

[0046] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, to facilitate the connection of the connector and the decorative part 5, in one embodiment, the first connecting part 2 includes a first snap-fit ​​member 21, which is connected to the main body 1, specifically, as shown... Figure 3 As shown, the first snap-fit ​​member 21 is spaced apart from the main body 1 in the first direction and together form a first snap-fit ​​groove 22. The decorative part 5 is provided with a second snap-fit ​​member 51, which is inserted into the first snap-fit ​​groove 22. In this way, the connector and the decorative part 5 are fixedly connected by a snap-fit ​​structure, which is simple and can be quickly assembled.

[0047] Furthermore, such as Figure 7 As shown, in order to improve the connection strength between the connector and the decorative part 5 and reduce the risk of the second snap-fit ​​member 51 falling out of the first snap-fit ​​groove 22, in one embodiment, the first snap-fit ​​member 21 is provided with a plurality of first snap teeth 211 on the side facing the snap-fit ​​groove. The plurality of first snap teeth 211 are spaced apart along the bottom wall of the first snap-fit ​​groove 22 in the direction of the opening. The second snap-fit ​​member 51 is provided with a plurality of second snap teeth 511 on the side opposite to the first snap-fit ​​member 21. The first snap teeth 211 are used to engage with the second snap teeth 511 so that the first snap-fit ​​member 21 and the second snap-fit ​​member 51 are elastically snapped together. Thus, after the second snap-fit ​​member 51 is inserted into the first snap-fit ​​groove 22, the second snap-fit ​​tooth 511 simultaneously engages with the first snap-fit ​​tooth 211. Multiple first snap-fit ​​teeth 211 and second snap-fit ​​teeth 511 are spaced apart on the bottom wall of the first snap-fit ​​groove 22 in the direction of the opening, increasing the contact area between the first snap-fit ​​member 21 and the second snap-fit ​​member 51. This reduces the risk of the second snap-fit ​​member 51 dislodging from the first snap-fit ​​groove 22 and ensures uniform force distribution at the contact points, improving the stability of the connection structure between the decorative part 5 and the connector. Furthermore, the elastic snap-fit ​​between the first snap-fit ​​member 21 and the second snap-fit ​​member 51 buffers vibrations during vehicle operation. The elastic connection between the decorative part 5 and the connector prevents stress concentration at the connection point caused by a rigid connection, reducing the risk of breakage of the first snap-fit ​​member 21 and the second snap-fit ​​member 51 and improving the overall stability of the connector and the decorative part 5 structure.

[0048] Furthermore, to improve the stability of the engagement between the first locking tooth 211 and the second locking tooth 511, the first locking tooth 211 is inclined away from the main body 1 in the direction from the opening of the bottom wall of the first locking groove 22, while the second locking tooth 511 is inclined closer to the main body 1 in the direction from the opening of the bottom wall of the locking groove. The first locking tooth 211 and the second locking tooth 511 form a self-locking structure, which blocks the second locking member 51 from disengaging along the direction from the opening of the bottom wall of the first locking groove 22, further reducing the risk of the second locking member 51 disengaging from the first locking groove 22.

[0049] like Figure 7As shown, the first connecting part 2 also includes a third snap-fit ​​member 23, which is located on the side of the main body 1 facing the first snap-fit ​​member 21. The third snap-fit ​​member 23 is connected to the main body 1, and the third snap-fit ​​member 23 and the main body 1 together form a second snap-fit ​​groove 24. The second snap-fit ​​groove 24 is arranged opposite to the first snap-fit ​​groove 22. The decorative part 5 is provided with a fourth snap-fit ​​member 52, and the second snap-fit ​​groove 24 is used for inserting the fourth snap-fit ​​member 52. In this way, the decorative part 5 and the connecting part are snapped together by the second snap-fit ​​member 51 and the first snap-fit ​​groove 22, and the fourth snap-fit ​​member 52 and the second snap-fit ​​groove 24, so that the connecting part structure of the decorative part 5 is wrapped inside the connecting part, forming an inverted structure, which improves the stability of the snap-fit ​​between the decorative part 5 and the connecting part and prevents the decorative part 5 from detaching from the connecting part.

[0050] Furthermore, such as Figure 7 As shown, when the decorative piece 5 is connected to the connector, the second snap-fit ​​piece 51 snaps into the first snap-fit ​​piece 21, and the fourth snap-fit ​​piece 52 is inserted into the second snap-fit ​​groove 24. In the second direction, one end and the middle of the decorative piece are reliably connected to the connector. During vehicle operation, to prevent the top of the decorative piece from wobbling relative to the connector, in one embodiment, to further improve the stability of the connection between the decorative piece 5 and the connector, the first connecting part 2 also includes a limiting member 25. The limiting member 25 is connected to the main body 1 and is located on the side of the main body 1 facing away from the door 6 in the second direction. The decorative piece 5 is provided with a limiting groove 53, and the limiting member 25 is inserted into the limiting groove 53 to limit the relative movement between the decorative piece 5 and the main body 1, especially the relative movement between the top of the decorative piece 5 and the main body 1. The position between the decorative piece 5 and the connector can be further limited by controlling the distance between the limiting member 25 and the limiting groove 53 on opposite sidewalls in the first direction. In this way, a multi-layered interlocking limiting structure is formed between the connector and the decorative piece 5, preventing the connector and the decorative piece 5 from separating. Furthermore, since the connector limits the trim piece 5 at the top, bottom, and middle, it not only improves the installation accuracy between the trim piece 5 and the door, but also further reduces the risk of deformation of the trim piece 5 and prevents the end of the trim piece 5 from warping. In one embodiment, to reduce the molding difficulty of the limiting groove 53, the trim piece 5 bends downward on the side facing away from the door 6 in the second direction to form a limiting protrusion 54, and the limiting protrusion 54 and the partial sidewall of the trim piece 5 facing the door 6 form a limiting groove 53.

[0051] like Figure 4 , Figure 6 and Figure 8As shown, the second connecting portion 3 is used to limit the position of the decorative part 5 and the door 6 in the first direction. To simplify the connection structure between the second connecting portion 3 and the door 6, in one embodiment, the second connecting portion 3 includes a first connecting segment 31. The first connecting segment 31 and the main body 1 are spaced apart in the first direction. The first connecting segment 31 and the main body 1 together form a third snap-fit ​​groove 32, which is used for at least a portion of the door 6 to be inserted. Thus, when the door 6 is connected to the second connecting portion 3, a portion of the door 6 can be inserted into the third snap-fit ​​groove 32, enabling the door 6 and the connecting part to be quickly assembled.

[0052] Furthermore, such as Figure 8 As shown, to improve the assembly efficiency of the door 6 and the connector, in one embodiment, the second connecting part 3 further includes a second connecting segment 33. The second connecting segment 33 is connected to the first connecting segment 31 and is located on the side of the first connecting segment 31 facing away from the main body 1. The side of the second connecting segment 33 facing the third locking groove 32 is provided with a guide arc surface 331. The distance between the guide arc surface 331 and the main body 1 decreases in the direction from the opening of the third locking groove 32 towards the bottom wall. When the door 6 and the connector are assembled, there is a large gap between the guide arc surface 331 and the main body 1. The door 6 and the connector can be inserted into the third locking groove 32 by the guiding action of the guide arc surface 331 without aligning them, which reduces the requirements for assembly accuracy. By setting the guide arc surface 331, automatic calibration and smooth insertion of the door 6 and the connector can be achieved, thus improving the assembly efficiency of the door 6 and the connector.

[0053] Furthermore, such as Figure 2 and Figure 4 As shown, after the connector is connected to the door 6, it is easy for the connector to slide along the third direction. To improve the installation accuracy and stability of the connector and the door 6, in one embodiment, the number of second connecting parts 3 is at least two, and they are spaced apart in the third direction. A positioning port 34 is formed between two adjacent second connecting parts 3. The door 6 is provided with a positioning protrusion 61, and the positioning port 34 is used for the positioning protrusion 61 to be inserted. In this way, after the connector is connected to the door 6, in the third direction, the positioning protrusion 61 is inserted into the positioning port 34, which can prevent the connector from moving in the third direction. The third direction is parallel to the length direction of the main body 1, which improves the installation accuracy of the connector and the door 6. This makes the position of the connector and the door 6 relatively fixed, improving the installation stability of the connector and the door 6.

[0054] like Figure 7 and 8 As shown, to further improve the stability of the connector installation with the door 6, a limiting part 12 is provided on the side of the main body 1 facing the door 6. The limiting part 12 is used to at least partially abut against the side opposite to the door 6. Figure 8As shown, in the second direction, the limiting part 12 can prevent the end of the main body 1 away from the third latching groove 32 from rotating. At the same time, the first connecting section 31 and the limiting part 12 are located on opposite sides of the door 6 in the third direction, so that the door 6 is reliably limited in the third direction, and the connecting part is prevented from moving in the third direction after it is connected to the door 6.

[0055] In this application, since at least a portion of the second connecting part 3 and the third connecting part 4 are spaced apart in the second direction, and cooperate to restrict the movement of the decorative part 5 relative to the door 6 in the second direction, the end of the decorative part 5 is prevented from tilting upward after installation with the door 6. Therefore, in the second direction, the connecting part is fixed to the position of the door 6 through the cooperation of the second connecting part 3 and the third connecting part 4. In the above embodiment, the second connecting part 3 is connected to the door 6 through the third snap-fit ​​groove 32.

[0056] like Figure 2 , Figure 4 , Figure 6 , Figure 9 and Figure 10 As shown, to simplify the connection structure between the third connecting part 4 and the door 6, in one embodiment, the third connecting part 4 includes a connected elastic member 41 and a fifth snap-fit ​​member 42. The elastic member 41 is connected to the main body 1 and is capable of elastic deformation relative to the main body 1 at least along a third direction. The door 6 is provided with an abutment part 62, at least a portion of which is located between the main body 1 and the fifth snap-fit ​​member 42. The fifth snap-fit ​​member 42 is used to abut against the side of the abutment part 62 facing away from the decorative member 5. When the door 6 is installed with the connector, the connector moves closer to the door 6 in the second direction, so that at least a portion of the door 6 begins to insert into the third latching slot 32. During this process, the fifth latching member 42 approaches and contacts the door 6, and the elastic member 41 undergoes elastic deformation, allowing the fifth latching member 42 to move below the abutment portion 62. As the door 6 and the third latching slot 32 are inserted into place, the fifth latching member 42 moves directly below the abutment portion 62 and abuts against the side of the abutment portion 62 facing away from the decorative member 5. In this way, the connector is fixed to the door 6 through the cooperation of the second connecting part 3 and the third connecting part 4.

[0057] Furthermore, such as Figure 10As shown, to simplify the structure of the elastic element 41, in one embodiment, the elastic element 41 includes a plurality of third connecting segments 411 and an arc-shaped segment 412. The plurality of third connecting segments 411 are spaced apart in the third direction, and an arc-shaped segment 412 is provided between adjacent third connecting segments 411. One third connecting segment 411 is connected to the main body 1, and another third connecting segment 411 is connected to the fifth snap-fit ​​member 42. The arc-shaped segment 412 is used to connect the ends of adjacent third connecting segments 411, ensuring continuous stress transmission, avoiding stress concentration, and improving the overall structural stability of the elastic element 41. It should be noted that, in the third direction, among the plurality of third connecting segments 411, the third connecting segment 411 connected to the main body 1 is the farthest from the fifth snap-fit ​​member 42, and the third connecting segment 411 connected to the fifth snap-fit ​​member 42 is the closest to the fifth snap-fit ​​member 42. The number of the third connecting section 411 can be adjusted according to actual needs. When the connector needs to be adapted to the thickness of the door 6 of different models and the assembly gap, the number and length of the third connecting section 411 and the radius of the arc transition end can be adjusted accordingly.

[0058] When installing the connector to the door 6, press down on the elastic member 41 to compress the arc-shaped segment 412 in a third-party direction from the third connecting segment 411 to the arc-shaped segment 412. This causes the fifth latching member 42 to pass through the opening 63 on the door 6, and under the elastic restoring force of the arc-shaped segment 412, the fifth latching member 42 abuts against the side of the abutting portion 62 facing away from the decorative member 5. Further, to facilitate the fifth latching member 42 passing through the opening 63 on the door 6 and abutting against the abutting portion 62, as follows... Figure 10 As shown, in one embodiment, the fifth latching member 42 has a guide slope 421 on one side of the elastic member 41 in the third direction. In the third direction from the elastic member 41 to the fifth latching member 42, the guide slope 421 is inclined toward the side closer to the second connecting portion 3. Thus, when the fifth latching member 42 approaches the opening 63, the elastic member 41 is compressed, and the guide slope 421 can slide relative to the side wall of the opening 63, so that the third connecting portion 4 and the door 6 can be latched, avoiding jamming and improving the assembly efficiency between the connector and the door 6.

[0059] Furthermore, such as Figure 3 As shown, in order to reduce the overall volume of the connector and facilitate the arrangement of the elastic element 41, in one embodiment, the main body 1 is provided with a through hole 11, and at least a portion of the elastic element 41 passes through the through hole 11 and protrudes from the outside of the main body 1. In this way, interference between the elastic element 41 and the main body 1 can be avoided. At the same time, the elastic element 41 has sufficient space to provide a large elastic force, thereby enhancing the stability of the connection between the connector and the door 6.

[0060] Furthermore, in order to facilitate the positioning of the third connecting part 4, and at the same time, to provide a better anti-warping effect on the end of the decorative part 5, such as... Figure 6 As shown, the third connecting part 4 is located at one end of the main body 1 in the third direction, and the second connecting part 3 and the third connecting part 4 are spaced apart in the third direction. In this way, the second connecting part 3 and the third connecting part 4 can form a significantly extended effective anti-warping arm in the length direction of the decorative part 5, effectively reducing the risk of the end of the decorative part 5 warping upward.

[0061] It should be noted that in the above embodiments, the second connecting portion 3 and the third connecting portion 4 of the connector are specifically connected to the sheet metal of the door 6. In this application, the connector can also be used to assemble the decorative part 5 with structures other than the door 6 in the vehicle, and can prevent the end of the decorative part 5 from warping when connected to the corresponding structure, while improving assembly efficiency. Furthermore, in the above embodiments, to improve the overall processing efficiency of the connector, the main body 1, the first connecting portion 2, the second connecting portion 3, and the third connecting portion 4 can be integrally formed using processes such as casting, injection molding, or bending. The process can be adapted to the molding material of the connector.

[0062] Based on the same concept, this application also provides a decorative component, such as... Figure 5 As shown, the decorative component includes a decorative element 5 and the aforementioned connector. The decorative element 5 has a connector at at least one end in the third direction, and the decorative element 5 is connected to the first connecting portion 2 of the connector. In one embodiment, if the decorative element 5 only has one end connected to the door 6 and then curves upwards, then only the connector needs to be pre-installed at the curved end of the decorative element 5, and then the entire decorative component is connected to the door 6. In another embodiment, if both ends of the decorative element 5 curve upwards after being connected to the door 6, then connectors are pre-installed at both ends of the decorative element 5. The number of connectors can be adaptively adjusted according to the specific connection between the decorative element 5 and the door 6. The decorative component can be sold as an independent product unit.

[0063] It should be noted that in the above embodiments, the decorative component 5 includes a trim panel and a sealant. The sealant enables the decorative component 5 to maintain a good sealing effect after it is connected to the door 6.

[0064] Based on the same concept, this application also provides a door 6 assembly, such as Figure 4 As shown, the door assembly 6 includes the door 6 and the aforementioned trim component, with the door 6 and trim component being detachably connected. Specifically, the door 6 is detachably connected to the second connecting portion 3 and the third connecting portion 4 on the connector, thereby improving the assembly efficiency of the trim component 5 and the door 6, preventing the ends of the trim component 5 from warping, enhancing the aesthetics and structural stability of the door assembly 6.

[0065] Based on the same concept, this application also provides a method for assembling a door assembly 6, which includes the following steps:

[0066] The decorative component 5 has a connector at at least one end in the third direction, and the decorative component 5 is connected to the first connecting part 2 so that the decorative component 5 and the connector are fixedly connected to form a decorative assembly;

[0067] The second connecting part 3 and the third connecting part 4 are connected to the door 6 so that the decorative component is connected to the door 6.

[0068] When assembling the door 6 assembly, the decorative part 5 and the connecting part can be pre-assembled to form a decorative component. Then, the decorative component is installed on the door 6. In this way, after the decorative component is installed on the door 6 assembly, the end of the decorative part 5 is prevented from tilting upwards, reducing the possibility of foreign objects entering the gap between the decorative part 5 and the door 6, thereby reducing the risk of abnormal noise and the detachment of the decorative part 5 during vehicle operation.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
