Description

Technical Field

[0001] This invention relates to the field of headliners, and more specifically to a headliner end cap structure, a headliner assembly having the end cap structure, and a vehicle. Background Technology

[0002] Most top trim end caps are installed using a simple plug-in method, but the risk of the end caps coming loose increases with time and repeated disassembly and assembly, reducing reliability.

[0003] The end cap has no connection point with the vehicle body, and the end is prone to curling up.

[0004] Currently, the mainstream connection solutions for top trim strips include:

[0005] 1. Use disposable plastic clips:

[0006] The buckle is inserted into the square hole on the roof and then locked in one direction.

[0007] The initial assembly provides sufficient holding force, but the barbs will inevitably deform when pulled out, requiring replacement with new clips for reassembly; otherwise, the holding force will decrease, and the roof trim may shift longitudinally and generate wind noise at high speeds.

[0008] In addition, the buckle and the trim body are separate structures, requiring pre-positioning fixtures, resulting in a longer assembly cycle.

[0009] 2. Rigid solution using metal spring clips and bolts;

[0010] Spring clips are welded onto the steel strip guide rail, and the trim strip is rigidly connected to the roof with bolts.

[0011] This solution offers high connection strength, but requires a dedicated tightening gun with a cycle time of ≥12 seconds; the bolt heads are exposed, requiring additional decorative caps, which compromises the appearance; repeated disassembly and assembly can easily cause stripping of sheet metal threads, leading to risks of water seepage and corrosion.

[0012] 3. Use adhesive tape for bonding, generally 3M tape is preferred.

[0013] The above solution is easy to connect, but the disadvantage is that the product is not rigid enough. Due to the large gap at the joint between the roof and the side panel, the surface is prone to plastic shrinkage marks and other appearance defects. In addition, long sections of tape are prone to curling and peeling during vehicle use.

[0014] Existing patent CN 203381568U discloses a buckle for fixing a roof trim strip to the roof of a vehicle; it is essentially a structure that uses a buckle and tape to install the roof trim strip; however, the problem of tape aging is still present.

[0052] An end cap structure 1-1 for a roof trim strip includes an end cap body, which includes a locking head 2 and a hinge plate 1. The end of the locking head 2 is connected to the end of the hinge plate 1. The locking head 2 can be connected to a pin on the roof 1-3. The hinge plate 1 can be connected to a steel strip guide rail 72 in the roof trim strip 1-2. The end cap structure 1-1 disclosed in this invention can realize the assembly and installation of the roof trim strip 1-2 on the upper end of the roof 1-3. Moreover, the end cap structure 1-1 disclosed in this invention has a simple locking mechanism, and subsequent disassembly can avoid destructive removal. Even if it is repeatedly disassembled, it will not increase the risk of loosening.

[0053] The end cap structure 1-1 disclosed in this invention is mainly used for the installation and connection of the top trim strip 1-2 on the roof 1-3. In this invention, the end cap structure 1-1 essentially acts as a connector.

[0054] Specifically, in this invention, the end cap structure 1-1 for the top trim strip mainly includes an end cap body, which is a long strip structure when projected. The end cap body includes a locking head 2 and a hinge plate 1. The locking head 2 is used to connect the top trim strip 1-2 to the pins on the vehicle body, while the hinge plate 1 acts as a locking element to fix and lock the top trim strip and the roof 1-3 with the end cap structure 1-1.

[0055] In this invention, the locking head 2 is connected to the hinge plate 1; the locking head 2 can be connected to the pin on the roof 1-3; the hinge plate 1 can be connected to the steel strip guide rail 72 in the roof trim 1-2; based on this design, the end cover structure 1-1 can realize the assembly and installation of the roof trim 1-2 on the roof 1-3.

[0056] Furthermore, in this invention, the locking head 2 includes a locking outer frame 21; a locking mechanism is provided inside the locking outer frame 21; the locking outer frame 21 is a U-shaped frame, and the locking mechanism is provided inside the locking outer frame 21. The locking mechanism is used to connect the pin, which facilitates the connection between the locking head 2 and the pin; in this invention, the locking mechanism includes two spaced locking strips 22; the locking strips 22 are provided with mounting grooves 24; the two locking strips 22 are spaced apart and provided with mounting grooves 24, and the two locking strips 22 cooperate with each other to realize the connection of the pin on the locking head 2; the locking strips 22 have a certain deformation capability, which facilitates the connection between the locking head 2 and the pin.

[0057] In addition, the mounting groove 24 described in this invention is a stepped groove; that is, it can form a stepped platform, which facilitates the hooking of the pin, and thus facilitates the connection and fixation of the locking head 2 and the pin.

[0058] In this invention, the mounting grooves 24 on the two locking bars 22 are arranged opposite to each other; the locking bars 22 are hooked onto the pins on the roof 1-3 through the mounting grooves 24; the horizontal projection of the mounting grooves 24 is an arc-shaped groove, and the two mounting grooves 24 are arranged opposite to each other to facilitate interaction with the head of the pin and achieve mutual positioning.

[0059] In this invention, the locking bar 22 includes a locking bar body 221; the locking bar body 221 is provided with a locking bar protrusion 222; the mounting groove 24 is provided on the locking bar protrusion 222; based on this design, the locking bar 22 has a T-shaped cross section, that is, the middle part of the locking bar 22 is convex; such a setting can ensure the structural strength of the locking bar 22, and at the same time facilitate the design of the mounting groove 24.

[0060] Furthermore, in this invention, the mounting groove 24 includes a recessed groove 241, a transition groove 242, and a guide groove 243; the depth of the recessed groove 241 is greater than the depth of the transition groove 242; based on this design, the recessed groove 241 and the transition groove 242 form a stepped platform structure, which facilitates the attachment of pins.

[0061] In this invention, the guide groove 243 is an arc-shaped groove; the guide groove 243 is connected to the upper recessed groove 241 through the transition groove 242; the arc-shaped guide groove 243 design facilitates the connection of the locking mechanism on the pin.

[0062] The other two locking bars 22 can compress and limit the pin.

[0063] Furthermore, the locking outer frame 21 described in this invention is provided with a sliding rib 23; one of the sliding ribs is used to cooperate with the steel strip guide rail 72 to provide good guidance for operation. In addition, the sliding rib 23 also plays a good restraining role to prevent the locking head 2 from detaching from the top trim strip 1-2.

[0064] In this invention, the locking head 2 also includes a stop block 26 disposed at the end of the locking outer frame 21; the lateral dimension of the stop block 26 is larger than the lateral dimension of the locking outer frame 21; the stop block 26 plays a good limiting role and can restrict the installation position of the end cover structure 1-1 on the top trim 1-2; at the same time, it can be used in conjunction with the limiting unit to ensure the stability of the end cover structure 1-1 installed and fixed on the top trim 1-2.

[0065] In this invention, the locking outer frame 21 is provided with a support and buffer unit on the side near the roof 1-3. The support and buffer unit includes two opposing support and buffer mechanisms. Each support and buffer mechanism includes at least one support leg 25 disposed on the locking outer frame 21. The support leg 25 is arranged at an angle. One end of the support leg 25 is connected to the locking outer frame 21, and the other end can press against the roof 1-3. One function of the support and buffer unit is to provide a buffering effect, and another function is to ensure the tightness of the locking head 2 and the pin, so as to prevent the roof trim 1-2 from moving up and down and causing abnormal noise during vehicle operation.

[0066] Furthermore, in this invention, a folding guide groove 3 is provided at the connection between the hinge plate 1 and the locking head 2; the end cap structure 1-1 is in its natural state; the included angle between the hinge plate 1 and the locking head 2 is an obtuse angle; the presence of the folding guide groove 3 can reduce the strength between the hinge plate 1 and the locking head 2, facilitating the subsequent flipping and folding operation of the hinge plate 1.

[0067] In this invention, the hinge plate 1 includes a chain plate body 11, and the chain plate body 11 is provided with a snap-fit ​​unit; the snap-fit ​​unit includes a snap-fit ​​block 6 provided on the side of the chain plate body 11. In this invention, the snap-fit ​​block 6 snaps onto the track flange 702 of the steel strip guide rail, thereby realizing the installation and fixation of the hinge plate 1 on the steel strip guide rail.

[0068] In addition, the snap-fit ​​block 6 described in this invention is provided with a hook groove 62; the hook groove 62 is conducive to forming a recessed structure and a hook structure; it is convenient to hang it on the steel strip guide rail later.

[0069] In this invention, the snap-fit ​​block 6 has an assembly arc surface 61 at one end near the top trim strip 1-2; based on this design, the snap-fit ​​block 6 forms an arc surface structure, which facilitates the snap-fit ​​block 6 to be snapped onto the steel strip guide rail; and reduces the difficulty of flipping the hinge plate 1.

[0070] In this invention, the chain plate body 11 is provided with a limiting unit; the limiting unit includes a limiting block 5 provided on the side of the chain plate body 11; the limiting block 5 is essentially a protrusion, mainly used to cooperate with the limiting groove 73 on the track flange 702 to prevent the end cover structure 1-1 from moving on the top trim 1-2.

[0071] A top trim strip 1-2 assembly includes a top trim strip 1-2, wherein the top trim strip 1-2 is connected to an end cap structure 1-1 for the top trim strip; the top trim strip 1-2 includes a steel strip guide rail 72; an outer decorative layer 71 is provided on the steel strip guide rail 72; in this invention, the top trim strip 1-2 is an outer decorative component, the steel strip guide rail 72 is used to ensure the structural strength of the top trim strip 1-2, and the outer decorative layer 71 serves as an appearance component; the two are fixedly connected.

[0072] In this invention, the steel strip guide rail 72 includes a steel strip body 723, and the end of the steel strip body 723 is provided with a track flange 702; the vertical cross section of the steel strip body 723 is inverted U-shaped; the steel strip body 723 is the main structure of the steel strip guide rail 72, and has an arched structure, while the track flange 702 acts as a guide rail; it is convenient to use with the sliding rib 23; one is to limit the longitudinal position of the locking head 2, and the other is to facilitate the pushing and insertion of the end cover structure 1-1 on the top trim 1-2.

[0073] Specifically, the track flange 702 in this invention includes a first flange plate 721 and a second flange plate 722; the first flange plate 721 is connected to the steel strip body 723 through the second flange plate 722; based on this design, the track flange 702 forms a hook structure, which facilitates the support and operation guidance of the sliding rib 23.

[0074] In this invention, the second flange plate 722 is an arc-shaped plate; the arc-shaped plate serves two purposes: reducing stress concentration and providing excellent assembly guidance, facilitating the snap-fit ​​block 6 to pass over the track flange 702 and achieve subsequent snap-fit ​​with the track flange 702.

[0075] Furthermore, in this invention, the track flange 702 is provided with a limiting groove 73 that cooperates with the limiting block 5; the width of the limiting groove 73 is not less than the length of the limiting block 5; the limiting groove 73 and the limiting block 5 cooperate with each other to realize the movement control of the end cover structure 1-1 in the length direction of the top trim 1-2.

[0076] Meanwhile, in this invention, at least one of the limiting blocks 5 has an inclined end face near the locking head 2; this setting allows the limiting block 5 to have a certain avoidance function. In other words, the contact area between one of the limiting blocks and the steel strip guide rail is floating, which facilitates the subsequent installation and removal of the hinge plate 1 on the top trim 1-2.

[0077] In subsequent use, the hinge plate can be shaken to tilt the inclined end face, making it easier for the limit block on the other side to be released from the restraint of the steel strip guide rail; thus facilitating actual disassembly and installation.

[0078] A vehicle includes a roof 1-3, on which the roof trim 1-2 assembly is connected; the roof trim 1-2 assembly is snapped onto a pin on the roof 1-3 via an end cap structure 1-1.

[0079] Example:

[0080] The end cap structure 1-1 mainly includes the end cap body; the end cap body is long and narrow, mainly including the locking head 2 and the hinge plate 1; the locking head 2 and the hinge plate 1 are generally integrally injection molded, and the locking head 2 and the hinge plate 1 are connected by a folding guide groove 3. In its natural state, the included angle is an obtuse angle, and it can be flipped into a flat angle under external force to achieve locking.

[0081] In this invention, the locking head 2 includes a locking outer frame 21: the locking outer frame 21 is a U-shaped frame with a through cavity inside for accommodating the locking mechanism, thereby facilitating connection to the pins on the roof 1-3.

[0082] Locking mechanism: Two symmetrically arranged elastic locking bars 22, with a T-shaped protrusion in the middle of the locking bar 22, and a stepped mounting groove 24 on the protrusion; the mounting groove 24 is connected in sequence by an upper recessed groove 241, a transition groove 242 and an arc-shaped guide groove 243 to form a pin hooking channel.

[0083] Sliding ribs 23: Arranged on both sides of the locking outer frame 21, they slide in cooperation with the track flanges 702 of the steel strip guide rail 72, and have both guiding and anti-detachment functions.

[0084] Stop block 26: Located at the tail end of the locking outer frame 21, it protrudes laterally and is used to abut against the end face of the top trim strip 1-2 to limit the insertion depth.

[0085] Support and buffer unit: Four inclined support legs 25 extend from the self-locking outer frame 21 near the roof 1-3, and the ends elastically press against the roof 1-3 sheet metal to form a pre-tightening force to suppress driving vibration and abnormal noise.

[0086] The hinge plate 1 includes a chain plate body 11 with uniform thickness and symmetrically arranged snap-fit ​​units and limiting units on both sides.

[0087] Snap-fit ​​unit: The outer side of the snap-fit ​​block 6 is provided with a hook groove 62 and the top is provided with an assembly arc surface 61; after flipping, the hook groove 62 hooks with the track flange 702 to achieve locking.

[0088] Limiting unit: The front end of the limiting block 5 is provided with an inclined clearance surface, which is inserted into the limiting groove 73 on the track flange 702 to limit the end cap from moving along the length of the top trim strip 1-2.

[0089] The top trim 1-2 assembly mainly includes the top trim 1-2, which includes a steel strip guide rail 72 and an outer trim layer 71.

[0090] The vertical cross-section of the steel strip guide rail 72 is inverted U-shaped, with rail flanges 702 extending in the same direction on both sides; the rail flanges 702 are composed of a first flange plate 721 and an arc-shaped second flange plate 722, forming a hook outline.

[0091] A limiting groove 73 is punched out on the flange, which fits with the end cap limiting block 5 with a clearance.

[0092] The outer layer 71 is made of flexible PVC / TPV material, and the surface can be designed to match the color and texture of the car body.

[0093] The roof panels of the vehicle have 1-3 sheet metal pre-welded or riveted with pins, the pin heads of which are mushroom-shaped.

[0094] During assembly:

[0095] Push the top trim strip 1-2 into the roof 1-3, and the pin enters the guide groove 243; continue pushing, and the pin slides along the transition groove 242 into the sinking groove 241, and the locking strip 22 elastically holds the pin; flip the hinge plate 1, and the snap block 6 automatically springs back after passing the second flange plate 722, the hook groove 62 hooks with the track flange 702, and at the same time the limit block 5 is embedded in the limit groove 73, and a "click" sound is emitted to complete the locking.

[0096] The locking head 2 and the hinge plate 1 of this invention form a two-step action of "hanging first and then flipping", which can be completed with one hand, and the assembly speed can be significantly improved.

[0097] The stepped mounting groove 24 + flexible locking strip 22 design is compatible with pin head manufacturing tolerance of ±0.5mm.

[0098] The support buffer unit provides a certain amount of compression to eliminate micro-impact noise caused by road surface excitation.

[0099] This embodiment achieves a reversible, reliable, and low-noise connection between the top trim strip 1-2 and the roof 1-3 through a two-stage locking mechanism of "locking head 2 hooking + hinge plate 1 flipping", as well as integrated features such as elastic support, limit anti-slip, and sliding guide. It can be widely used in the roof trim systems of passenger cars, commercial vehicles, and new energy vehicles.

[0100] The end cap structure 1-1 disclosed in this invention is essentially a connector, mainly including a locking head 2 and a hinge plate 1. The locking head 2 can be inserted into the steel strip guide rail 72 in the top trim strip 1-2; the hinge plate 1 can be rotated and locked into the steel strip guide rail 72; and the locking mechanism on the locking head 2 can be locked onto the pin on the roof 1-3.

[0101] In this invention, the hinge plate 1 completely prevents the end cap structure 1-1 from detaching from the top trim strip 1-2; even repeated disassembly and reassembly 10 times will not increase the risk of detachment; and it can significantly improve the reliability of the connection between the top trim strip 1-2 and the roof 1-3.

[0102] In this invention, the end cover structure 1-1 is first inserted into the steel strip guide rail 72 of the top trim 1-2 along the X direction of the whole vehicle, then the hinge plate 1 is rotated to make it snap into the steel strip guide rail 72, and finally the top trim 1-2 assembly is snapped into the pin of the roof 1-3 in the Z direction.

[0103] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
