Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, specifically to an upper trim assembly for a vehicle body door frame, a vehicle door, and a vehicle. Background Technology

[0002] Currently, a trim strip is installed on the upper sealing strip of the vehicle door frame to improve the aesthetics of the door when closed. This trim strip is a narrow, elongated component with a U-shaped groove, and at least one end has an opening. Since the aesthetics of the end of the trim strip need to be considered after installation on the door frame, an end cap is required at the end opening to cover, seal, and protect the end of the trim strip.

[0003] In related technologies, the end cap is mainly fixed to the U-shaped slot of the upper trim strip in the following way: for example, glue is injected into the slot of the upper trim strip, and then the end cap is inserted into the slot. After the glue solidifies, the end cap can be fixed in the slot.

[0004] However, if the adhesive is stored in an unsuitable environment before use, or if the vehicle is frequently driven in harsh environments such as low or high temperatures, it is prone to adhesion failure, which will affect the assembly stability of the end cap and the upper trim strip.

Since the upper trim strip has an end opening that communicates with the slot, the end cap body can be slidably embedded in the slot of the upper trim strip from the end opening. After the end cap body is embedded in the slot, the end cap sealing part at one end of the end cap body can be sealed and connected to the end opening of the upper trim strip, thereby ensuring the connection and sealing between the end cap and the upper trim strip.

[0027] Since the knob assembly is movably installed within the mounting hole structure, by operating the knob assembly, for example, by rotating it clockwise, the end cap body will expand and deform along the first direction (the vertical direction of the vehicle). The end cap body will drive the first support foot at its end along the first direction to move along the first direction, so that the first support foot abuts against the side wall of the slot along the first direction, thereby quickly fixing the end cap structure to the slot of the upper trim strip.

[0028] Compared to related technologies that require adhesive to bond the end cap to the slot of the upper trim strip, which can easily cause the end cap to detach from the upper trim strip if the adhesive fails, this utility model uses a knob assembly to rotate and cause the end cap body in the end cap structure to expand and deform. This causes the two first support legs set at both ends of the end cap body along the first direction to abut against the side wall of the slot along the first direction, thereby enabling the end cap structure to be quickly and stably installed in the slot of the upper trim strip, improving the assembly stability and assembly efficiency of the end cap structure and the upper trim strip.

[0051] To address the problems existing in the aforementioned related technologies, this embodiment provides an upper trim assembly for a vehicle body door frame, a vehicle door, and a vehicle.

[0052] like Figure 1 As shown in the figure, an upper trim strip assembly for a vehicle door frame provided by this utility model includes an upper trim strip 1, an end cap structure 2, and a knob assembly 3. The upper trim strip 1 is provided with a slot 110 and an end opening communicating with the slot 110. The end cap structure 2 includes an end cap body 21, an end cap sealing part 22, and a first support leg part 23. The end cap body 21 is embedded in the slot 110. The end cap body 21 is provided with first support legs 23 at both ends along a first direction. The end cap body 21 is provided with a mounting hole structure 2110. The knob assembly 3 is movably installed in the mounting hole structure 2110. The end cap body 21 is used to generate deformation along the first direction when the knob assembly 3 is rotated, so as to drive the first support leg part 23 to move along the first direction to abut against the side wall of the slot 110 along the first direction.

[0053] The end cap body 21 is provided with an end cap sealing part 22 at its end along the second direction, and the end cap sealing part 22 is sealed to the end opening; the first direction refers to the vertical direction of the vehicle, and the second direction refers to the front-rear direction of the vehicle.

[0054] Specifically, the upper trim strip assembly is mounted on the vehicle door frame. The upper trim strip 1 is a long and narrow component, and its end face in the extending direction can be substantially U-shaped. Therefore, the upper trim strip 1 has a slot 110 that can be substantially cuboid. At least one end of the upper trim strip 1 in the extending direction is provided with the end opening. The first direction refers to the vertical direction (or up-down direction) of the vehicle. The first direction can be connected with... Figure 1Since the Z-axis is parallel in the coordinate system, the sidewall of the slot 110 along the first direction refers to the upper and lower sidewalls of the slot 110.

[0055] The end cap body 21 is provided with the end cap sealing part 22 at its end along the second direction, where the second direction refers to the longitudinal direction of the vehicle, and it can be used with... Figure 1 The X-axis is parallel in the coordinate system; the end cap sealing part 22, the first support foot part 23 and the end cap body 21 can be constructed as an integral structure to ensure that the end cap structure 2 has a certain strength; wherein, the integral structure can be made of flexible materials, such as sodium fatty alcohol polyoxyethylene ether sulfate (abbreviated as AES material), or polyoxymethylene (abbreviated as POM plastic), or acrylonitrile-styrene-butadiene copolymer (abbreviated as ABS resin), etc.

[0056] The end cap sealing part 22 can be a plate-shaped structure, and the plate-shaped structure can be connected to the end cap body 21 at an angle, for example, perpendicularly. The surface area of ​​the end cap sealing part 22 can be larger than the end opening area of ​​the upper trim strip 1 to ensure that the end cap sealing part 22 can completely seal the end opening of the upper trim strip 1.

[0057] The end cap body 21 has a mounting hole structure 2110 in the middle, which is used to install the knob assembly 3. The knob assembly 3 is movably installed in the mounting hole structure 2110, meaning that the knob assembly 3 can rotate within the mounting hole structure 2110 under the rotational force of the operator.

[0058] Since the end cap structure 2 is made of the aforementioned flexible material, when the knob assembly 3 located in the mounting hole structure 2110 is rotated, for example clockwise, the end cap body 21, made of flexible material, can expand and deform in the first direction at the mounting hole structure 2110, so that the end cap body 21 drives the first support leg 23 to move in the first direction, causing the first support leg 23 to abut against the side wall of the upper trim strip 1 in the first direction.

[0059] In this embodiment, the upper trim assembly of the vehicle door frame mainly includes an upper trim 1, an end cap structure 2, and a knob assembly 3. The end cap structure 2 includes an end cap body 21, an end cap sealing part 22, and a first support leg part 23. Before the end cap body 21 is embedded in the slot 110, the knob assembly 3 can be connected to the mounting hole structure 2110 of the end cap body 21 to install the knob assembly 3 on the end cap body 21. Since the upper trim 1 has an end opening that communicates with the slot 110, the end cap body 21 can be slidably embedded in the slot 110 of the upper trim 1 from the end opening of the upper trim 1. After the end cap body 21 is embedded in the slot 110, the end cap sealing part 22 at one end of the end cap body 21 can be sealed and connected to the end opening of the upper trim 1, thereby ensuring the sealing of the connection between the end cap and the upper trim 1.

[0060] Since the knob assembly 3 is movably installed in the mounting hole structure 2110, by operating the knob assembly 3, for example, rotating it clockwise, the end cap body 21 will expand and deform along the first direction (the vertical direction of the vehicle). The end cap body 21 will drive the first support leg 23 at its end along the first direction to move along the first direction, so that the first support leg 23 abuts against the side wall of the slot 110 along the first direction, thereby quickly fixing the end cap structure 2 to the slot 110 of the upper trim strip 1.

[0061] Compared to related technologies, which require adhesive to bond the end cap to the slot 110 of the upper trim 1, and which can easily cause the end cap to detach from the upper trim 1 if the adhesive fails, this invention uses a knob assembly 3 to rotate and cause the end cap body 21 in the end cap structure 2 to expand and deform. This causes the two first support legs 23 at both ends of the end cap body 21 along the first direction to abut against the side wall of the slot 110 along the first direction, thereby enabling the end cap structure 2 to be quickly and stably installed in the slot 110 of the upper trim 1, thus improving the assembly stability and efficiency of the end cap structure 2 and the upper trim 1.

[0062] Optionally, combined Figure 2 As shown, the knob assembly 3 includes a knob structure 31, the end cap body 21 includes an annular portion 211 and two first arc-shaped slide portions 212, the two first arc-shaped slide portions 212 are disposed opposite to each other on the inner wall of the annular portion 211, the mounting hole structure 2110 includes a first mounting hole, the two first arc-shaped slide portions 212 surround the first mounting hole, at least a portion of the knob structure 31 is embedded in the first mounting hole, and the annular portion 211 is used to generate deformation along the first direction when the knob structure 31 is rotated.

[0063] Specifically, the annular portion 211 can be an elliptical ring structure, a rectangular ring structure, or a rhomboid ring structure, etc. Two first arc-shaped slide portions 212 are arranged at intervals on the inner wall of the annular portion 211.

[0064] Before the end cap body 21 undergoes expansion deformation along the first direction, the size of the first mounting hole along the first direction is smaller than the size of the first mounting hole along the second direction. For example, the first mounting hole is a non-circular hole, such as an elliptical hole. "At least part of the knob structure 31 is embedded in the first mounting hole" means that the entire structure of the knob structure 31 is embedded in the first mounting hole, or that a part of the knob structure 31 is embedded in the first mounting hole.

[0065] Since the knob structure 31 can rotate within the first mounting hole, the knob structure 31 can be slidably connected to the inner wall of the first mounting hole.

[0066] The first support foot 23 is provided at both ends of the annular portion 211 along the first direction.

[0067] The knob structure 31 can be made of a material with a certain degree of hardness, such as polybutylene terephthalate (PBT material) or polyoxymethylene (POM plastic).

[0068] In this optional embodiment, since at least a portion of the knob structure 31 is embedded in the first mounting hole formed between the two first arc-shaped slide portions 212, rotating the knob structure 31 clockwise will spread the two first arc-shaped slide portions 212 apart. The two first arc-shaped slide portions 212 will then cause the annular portion 211 to expand and deform along the first direction, causing the annular portion 211 to move the two first support legs 23 along the first direction. The two first support legs 23 will then abut against the sidewall of the slot 110 along the first direction, thus fixing the end cap body 21 within the slot 110. The annular portion 211 ensures that the end cap body 21 can undergo sufficient expansion and deformation.

[0069] Optionally, combined Figure 2 As shown, the knob structure 31 includes a knob body 311 and a knob protrusion 312. The knob body 311 is a cylindrical structure, and the knob protrusion 312 is respectively provided at both radial ends of the knob body 311. Each of the first arc-shaped slide portions 212 is provided with a positioning groove 2121. The knob protrusion 312 is used to be embedded in the positioning groove 2121 when the end cap body 21 undergoes expansion deformation along the first direction.

[0070] Specifically, the knob structure 31 may include at least two knob protrusions 312, which are disposed opposite to each other at the radial ends of the knob body 311.

[0071] The knob body 311 and the knob protrusion 312 can be constructed as an integral structure to ensure that the knob structure 31 has a certain mechanical strength.

[0072] The two inner walls of the two first arc-shaped slide sections 212 are respectively provided with positioning grooves 2121, the shape and size of which match the shape and size of the knob protrusion 312.

[0073] For example, if the knob protrusion 312 is a polygonal prism structure, then the positioning groove 2121 can be a rectangular groove; if the knob protrusion 312 is a cylindrical structure, then the positioning groove 2121 can be a circular groove.

[0074] In this optional embodiment, after the end cap body 21 is embedded in the slot 110 of the upper trim strip 1, the operable knob structure 31 can be rotated clockwise in the first mounting hole so that the end cap body 21 expands and deforms along the first direction, thereby driving the first support leg 23 to abut against the corresponding side wall of the slot 110. At this time, each knob protrusion 312 can be inserted into the corresponding positioning groove 2121 so as to lock the position of the knob structure 31 through the positioning groove 2121 to prevent the knob structure 31 from deflecting, thereby achieving stable fixing of the end cap body 21 in the slot 110.

[0075] Optionally, combined Figure 3 As shown, the knob structure 31 further includes a rotation guide portion 313, which is disposed on the end face of the knob body 311 facing the slot 110; the end cover body 21 further includes two second arc-shaped slide portions 213, which are disposed opposite to each other on the inner wall of the annular portion 211, and the second arc-shaped slide portions 213 and the first arc-shaped slide portion 212 are arranged in a third direction; the mounting hole structure 2110 further includes a second mounting hole, which is formed by the two second arc-shaped slide portions 213; the rotation guide portion 313 is embedded in the second mounting hole and is used to rotate within the second mounting hole.

[0076] Specifically, the knob body 311 along Figure 3 A rotary guide 313 is provided on the end face of the positive Y-axis in the coordinate system. The rotary guide 313 can be a circular plate structure or a cylindrical structure. And the second mounting hole can be a circular hole.

[0077] The second arc-shaped slide section 213 and the first arc-shaped slide section 212 are disposed at a distance along a third direction on the inner wall of the annular section 211; the third direction can be connected with... Figure 3 In the coordinate system, the Y-axis is parallel, and this third direction refers to the left and right directions of the vehicle.

[0078] The diameter of the second mounting hole formed by the two second arc-shaped slide sections 213 is smaller than the diameter of the first mounting hole formed by the two first arc-shaped slide sections 212.

[0079] The diameter of the rotary guide 313 is slightly smaller than the diameter of the second mounting hole so that the rotary guide 313 can be smoothly inserted into the second mounting hole.

[0080] In this optional embodiment, when the knob body 311 and the knob protrusion 312 rotate within the first mounting hole, the rotation guide portion 313 of the knob structure 31 can rotate within the second mounting hole formed between the two second arc-shaped slide portions 213. This allows the second mounting hole formed by the two second arc-shaped slide portions 213 to cooperate with the rotation guide portion 313, so that the two second arc-shaped slide portions 213 can act as rotation guides for the knob body 311 and the knob protrusion 312 within the first mounting hole. This prevents the knob body 311 and the knob protrusion 312 from becoming eccentric or offset during rotation, thereby ensuring the uniformity of the expansion deformation of the end cap body 21 along the first direction and improving the stability of the end cap body 21 fixed in the slot 110 of the upper trim strip 1.

[0081] Optionally, combined Figure 4 As shown, the knob assembly 3 also includes a knob connector 32. The end cap body 21 has an annular groove 210 on its inner sidewall facing the slot 110. The knob connector 32 is embedded in the annular groove 210. The knob structure 31 and the knob connector 32 are detachably connected.

[0082] Specifically, the end cap body 21 faces the inner wall of the slot 110 (i.e., the end cap body 21 along the inner wall of the slot 110). Figure 4 An annular groove 210 is provided on the positive Y-axis of the coordinate system, and the annular groove 210 can be located on the left side of the second arc-shaped slide section 213.

[0083] The knob connector 32 can be embedded in the annular groove 210.

[0084] In this optional embodiment, since the knob structure 31 is detachably connected to the knob connector 32 embedded in the annular groove 210, the knob connector 32 not only allows the knob structure 31 to be detachably installed in the mounting hole structure 2110, which helps to ensure the stable installation of the knob structure 31 and subsequent maintenance, but also prevents the knob connector 32 from protruding from the annular groove 210. This avoids structural interference between the knob connector 32 and the upper trim strip 1 when the knob assembly 3 is installed in the mounting hole structure 2110 of the end cap body 21, thus ensuring the smooth assembly of the end cap structure 2 and the upper trim strip 1.

[0085] Optionally, combined Figure 2 , Figure 7 and Figure 8 As shown, the knob assembly 3 is provided with a connecting groove 3110, which is used for inserting a tool to operate the knob assembly 3 to rotate.

[0086] Specifically, the knob body 311 of the knob assembly 3 is provided with a connecting groove 3110, the shape of which can be a polygonal prism groove structure, for example... Figure 2 and Figure 7The connecting groove 3110 in the middle can be a rectangular groove, and the knob body 311 of the knob structure 31 can be a column structure with a connecting groove 3110 at one end and a through hole 3130 at the other end.

[0087] The end of the tool can be matched with the shape of the connecting groove 3110.

[0088] In this optional embodiment, since the knob body 311 of the knob assembly 3 is provided with a connecting groove 3110, a tool can be inserted into the connecting groove 3110 so that the operator can apply rotational force to the knob assembly 3 with the tool, thereby saving manual effort for the rotation of the knob assembly 3 in the mounting hole structure 2110 and correspondingly improving the convenience of rotation of the knob assembly 3 in the mounting hole structure 2110.

[0089] Optionally, the knob connector 32 can be detachably connected to the knob structure 31 in the following manner, for example, by combining... Figure 3 , Figures 5 to 8 As shown, the knob connector 32 includes a disc structure 321 and a insert connector 322. The insert connector 322 is disposed in the middle of the disc structure 321. The disc structure 321 is embedded in the annular groove 210. The inner sidewall of the knob structure 31 facing the slot 110 has a through hole 3130. The insert connector 322 passes through the through hole 3130. The end of the insert connector 322 away from the disc structure 321 is located in the connecting groove 3110.

[0090] Specifically, the insert connector 322 can be integrally disposed at the center of the disc structure 321. The disc structure 321 can be disposed in the annular groove 210, and the end of the insert connector 322 away from the disc structure 321 can be inserted into the through hole 3130 of the knob structure 31.

[0091] The insert connecting part 322 can be a complete annular structure or it can include insert structures arranged in annular intervals. Each insert structure at the part of the knob structure 31 can be provided with a barb structure. The barb structure is located in the connecting groove 3110, so as to reduce the possibility of the knob connector 32 disengaging from the through hole 3130 through the barb structure of the insert connecting part 322.

[0092] In this optional embodiment, when the knob connector 32 is connected to the knob structure 31, the insert connector 322 is inserted into the through hole 3130 of the knob structure 31, so that the insert connector 322 and the knob structure 31 are detachably connected through the insertion of the insert connector 322 into the through hole 3130. The end of the insert connector 322 away from the disc structure 321 is located in the connecting groove 3110, so that the barb structure of the end of the insert connector 322 away from the disc structure 321 can effectively improve the assembly stability of the knob connector 32 and the knob structure 31. The disc structure 321 can be embedded in the annular groove 210. The disc structure 321 can rotate synchronously in the annular groove 210 as the knob structure 31 rotates. This ensures that the annular groove 210 not only ensures the stability of the knob structure 31's rotation in the mounting hole structure 2110, but also prevents the disc structure 321 from protruding from the annular groove 210, thus avoiding interference between the disc structure 321 and the end cap body 21's mounting in the slot 110 of the upper trim strip 1.

[0093] Optionally, combined Figure 13 and Figure 14 As shown, the knob connector 32 includes a disc structure 321, a connecting post 323, and a connecting cap 324. The connecting post 323 is disposed in the middle of the disc structure 321. The end of the connecting post 323 away from the disc structure 321 is connected to the connecting cap 324. The disc structure 321 is embedded in the annular groove 210. The side wall of the knob structure 31 facing the slot 110 has a through hole 3130. The connecting post 323 passes through the through hole 3130. The connecting cap 324 is located in the connecting groove 3110.

[0094] Specifically, the two ends of the connecting post 323 are respectively connected to the center part of the disc structure 321 and the connecting cap 324, so as to connect the disc structure 321, the connecting post 323 and the connecting cap 324 into a knob connector 32 with an integral structure. The connecting post 323 and the connecting cap 324 can basically form a mushroom nail structure. The disc structure 321 can be set in the annular groove 210, the connecting post 323 passes through the through hole 3130 of the knob structure 31, and the connecting cap 324 can be entirely placed in the connecting groove 3110.

[0095] In this optional embodiment, when the knob connector 32 is connected to the knob structure 31, the connecting post 323 is inserted into the through hole 3130 of the knob structure 31, so that the connecting cap 324 is located in the connecting groove 3110. The disc structure 321 is embedded in the annular groove 210 of the end cap body 21 to prevent the connecting cap 324 of the knob connector 32 from disengaging from the connecting groove 3110 of the knob structure 31, thereby effectively improving the assembly stability of the knob connector 32 and the knob structure 31. The disc structure 321 can be embedded in the annular groove 210, and the disc structure 321 can rotate synchronously in the annular groove 210 with the rotation of the knob structure 31. This ensures that the annular groove 210 not only ensures the stability of the rotation of the knob structure 31 in the mounting hole structure 2110, but also prevents the disc structure 321 from protruding from the annular groove 210, thus avoiding interference between the disc structure 321 and the slot 110 of the end cap body 21 when it is installed in the upper trim strip 1.

[0096] Optionally, combined Figure 15 and Figure 16 As shown, the knob connector 32 includes a disc structure 321 and a connector 325. The connector 325 is disposed in the middle of the disc structure 321. The disc structure 321 is embedded in the annular groove 210. The outer circumferential wall of the connector 325 is provided with an external thread 3251. The side wall of the knob structure 31 facing the slot 110 is provided with a threaded hole. The external thread 3251 of the connector 325 is threadedly connected to the threaded hole.

[0097] Specifically, the connector 325 can be a bolt structure, so the circumferential sidewall of the connector 325 is provided with external threads. The end of the connector 325 can be connected to the center part of the disc structure 321 to connect the disc structure 321 and the connector 325 into a knob connector 32 with an integral structure. The disc structure 321 can be set in the annular groove 210. The center part of the knob structure 31 has a threaded hole. The inner diameter of the threaded hole matches the outer diameter of the connector 325. The connector 325 passes through the threaded hole of the knob structure 31, and at least a part of the connector 325 is located in the threaded hole.

[0098] In this optional embodiment, when the knob connector 32 is connected to the knob structure 31, the external thread 3251 of the connector head 325 is threadedly connected to the threaded hole of the knob structure 31 to prevent the connector head 325 of the knob connector 32 from disengaging from the threaded hole of the knob structure 31, thereby effectively improving the assembly stability of the knob connector 32 and the knob structure 31. The disc structure 321 can be embedded in the annular groove 210. The disc structure 321 can rotate synchronously in the annular groove 210 as the knob structure 31 rotates. This ensures that the annular groove 210 not only ensures the stability of the rotation of the knob structure 31 within the mounting hole structure 2110, but also prevents the disc structure 321 from protruding from the annular groove 210, thus avoiding interference between the disc structure 321 and the slot 110 of the end cap body 21 when it is installed in the upper trim strip 1.

[0099] Optionally, combined Figure 9 and Figure 10 As shown, the upper trim strip 1 includes a trim strip body 11 and a flexible body 12. The two ends of the trim strip body 11 along the first direction are respectively connected to the flexible body 12, and the first support foot 23 is used to abut against the flexible body 12.

[0100] Specifically, the trim body 11 is a long and narrow component, and its end face in the extension direction can be basically U-shaped. In other words, the trim body 11 includes an arc plate and two folded edges. The arc plate is connected to the corresponding folded edges at both ends along the first direction. Therefore, the trim body 11 has the slot 110 that can be basically rectangular. The two flexible bodies 12 can also be long and narrow components, and each flexible body 12 has a slot that penetrates itself. The two flexible bodies 12 are spaced apart along the first direction, and the two folded edges of the trim body 11 along the first direction are respectively inserted into the slots of the two flexible bodies 12. Each flexible body 12 can cover the upper or lower sidewall (i.e., the two folded edges) of the trim body 11 along the first direction to fix the two flexible bodies 12 to the trim body 11.

[0101] The soft body 12 can be made of flexible materials such as rubber or silicone.

[0102] In this optional embodiment, since the first support leg 23 is used to abut against the soft body 12 on the side wall of the slot 110 embedded in the upper trim 1 along the first direction, the soft body 12 not only increases the friction between the first support leg 23 and the trim body 11 in the end cover structure 2, thereby improving the stability of the end cover structure 2 installed in the slot 110 of the upper trim 1, but also plays a shock absorption and buffering role to reduce vibration and noise when closing the car door.

[0103] Optionally, combined Figure 10 As shown, the end cap body 21 is provided with a plurality of first support legs 23 arranged at intervals along the second direction at the end along the first direction.

[0104] Specifically, the end cap body 21 is provided with a plurality of first support legs 23 at the end of the end cap body 21 along the first direction, such as the upper end (or lower end), and the plurality of first support legs 23 at the same end of the end cap body 21 along the first direction can be spaced apart along the second direction.

[0105] In this optional embodiment, since multiple first support legs 23 are provided at the same end of the end cap body 21 along the first direction and spaced apart along the second direction, the multiple first support legs 23 spaced apart at the same end of the end cap body 21 effectively increase the connection point between the end cap structure 2 and the upper trim strip 1, preventing the end cap structure 2 from detaching from the end opening of the upper trim strip 1, and further improving the assembly stability of the end cap structure 2 and the upper trim strip 1.

[0106] Optionally, combined Figure 10 As shown, two of the first support legs 23 located at the same end of the end cap body 21 along the first direction are arranged at an angle.

[0107] Specifically, two of the first support legs 23 located at the same end of the end cap body 21 along the first direction extend toward the direction away from the annular portion 211, and the extension lines of the two first support legs 23 are arranged at an angle.

[0108] In this optional embodiment, when the knob assembly 3 is rotated to cause the end cap body 21 to expand and deform along the first direction, multiple first support legs 23 at each end of the end cap body 21 along the first direction can respectively abut against the corresponding sidewall of the slot 110 along the first direction. Since two of the first support legs 23 at the same end of the end cap body 21 along the first direction are set at an angle, while ensuring the assembly stability of the end cap structure 2 and the upper trim strip 1, the two first support legs 23 set at an angle can increase the expansion and deformation of the end cap structure 2 along the first direction. Figure 10 The positive X-axis in the coordinate system removes the detachment resistance of the upper trim strip 1, further increasing the assembly stability of the end cap structure 2 and the upper trim strip 1.

[0109] Optionally, combined Figure 10 As shown, the end cap structure 2 also includes an intermediate connecting part 214, the two opposite ends of which are connected to the end cap body 21 and the end cap sealing part 22, respectively.

[0110] Specifically, the annular portion 211 in the end cap body 21 and the end cap sealing portion 22 can be connected by an intermediate connecting portion 214, which can be a plate-like structure.

[0111] Since the two ends of the intermediate connecting part 214 along the second direction are respectively connected to the end cap body 21 and the end cap sealing part 22, in other words, the intermediate connecting part 214 is equivalent to increasing the length of the entire end cap structure 2 in the extension direction, thereby increasing the connection area between the end cap structure 2 and the upper trim 1, which is equivalent to enhancing the connection stability between the end cap body 21 and the upper trim 1.

[0112] Optionally, combined Figure 10 As shown, the middle connecting part 214 is provided with a second support foot 215 at its end along the first direction, and the second support foot 215 is used to abut against the flexible body 12.

[0113] Specifically, a second support foot 215 is provided at each end of the intermediate connecting portion 214 along the first direction. The second support foot 215 may be an arc-shaped plate structure, and the curvature of the arc-shaped plate structure may match the curvature of the end of the upper trim strip 1 along the first direction.

[0114] Combination Figure 10 As shown, the number of second support legs 215 at the same end of the intermediate connecting portion 214 along the first direction can be two.

[0115] In this optional embodiment, since the first support foot 23 at the end of the end cap body 21 along the first direction abuts against the soft body 12, and the second support foot 215 at the end of the intermediate connecting part 214 along the first direction abuts against the soft body 12, it is equivalent to further increasing the connection length between the end cap structure 2 and the upper trim strip 1 along the second direction, increasing the separation resistance of the end cap structure 2 from the end opening of the upper trim strip 1, and further increasing the assembly stability of the end cap structure 2 and the upper trim strip 1.

[0116] Optionally, combined Figure 4 As shown, the intermediate connecting part 214 has a protruding structure 216 facing the inner wall of the slot 110, and the protruding structure 216 abuts against the inner wall of the slot 110.

[0117] Specifically, the protruding structure 216 may be at least one of a rib or a protrusion.

[0118] The protruding structure 216 can be integrally formed along the middle connecting part 214. Figure 4 On the surface in the positive Y-axis direction of the coordinate system.

[0119] In this optional embodiment, since the intermediate connecting portion 214 is along Figure 4The protruding structure 216 provided on the surface in the positive Y-axis direction of the coordinate system (i.e., the direction towards the upper trim 1) abuts against the inner wall of the slot 110, thereby increasing the frictional force with the slot 110 of the upper trim 1 through the protruding structure 216, so as to reduce the possibility of the end cap structure 2 coming off from the end opening of the upper trim 1.

[0120] The process of the knob assembly 3 in the upper trim of the door frame before and after rotation is as follows:

[0121] Operating end cap structure 2 along Figure 1 The X-axis of the coordinate system moves in the opposite direction to slide into the slot 110 from the end opening of the upper trim 1. During the installation of the end cap structure 2 into the slot 110 of the upper trim 1, the two knob protrusions 312 in the knob assembly 3 remain horizontal. At this time, the end cap body 21 is in a free state, and the dimensions of the two first support legs 23 along the first direction are smaller than the dimensions of the slot 110 along the first direction, ensuring that the end cap structure 2 slides smoothly into the slot 110 of the upper trim 1 with no or low resistance. Figure 11 As shown.

[0122] After the end cap body 21 of the end cap structure 2 is in the preset position within the slot 110, a tool can be inserted into the connecting groove 3110 of the knob structure 31 to rotate the knob structure 31 clockwise by 90 degrees. At this time, the two knob protrusions 312 in the knob structure 31 are respectively in the positioning grooves 2121 corresponding to the first arc-shaped slide portion 212, so that the annular portion 211 of the end cap body 21 is opened (i.e., expansion deformation along the first direction is generated), so that the end cap body 21 drives the two first support legs 23 to move along the first direction, so that the two first support legs 23 respectively abut against the side wall of the slot 110 along the first direction, realizing the alignment of the end cap structure 2 with the upper trim 1 along the first direction ( Figure 12 Locking is performed in the Z-axis direction of the coordinate system, and then the tool is removed from the connecting groove 3110, thereby realizing the assembly of the end cap structure 2 and the upper trim strip 1.

[0123] During later maintenance, a tool can be inserted into the connecting groove 3110 of the knob structure 31 to rotate the knob structure 31 counterclockwise by 90 degrees. At this time, the two knob protrusions 312 in the knob structure 31 disengage from the corresponding positioning grooves 2121 and are in a horizontal state. This allows the end cap body 21 to retract and return to its original shape after losing the squeezing force of the knob assembly 3. The end cap body 21 drives the two first support legs 23 to retract, causing the two first support legs 23 to disengage from the side wall of the slot 110 along the first direction. Then, the end cap structure 21 can be rotated along the first direction. Figure 1 The X-axis of the coordinate system moves in the positive direction to disengage from the end opening of the upper trim 1, thereby enabling the disassembly of the end cap structure 2 from the upper trim 1.

[0124] This utility model provides a vehicle door, including an upper trim strip assembly of the vehicle body door frame as described in the above embodiment, and an upper sealing strip, wherein the upper trim strip 1 of the upper trim strip assembly of the vehicle body door frame is sealed and connected to the upper sealing strip.
