Detailed Description

The practice and use of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

In this specification, directional expressions such as top, bottom, front, rear, left, right, and the like, which are used when describing positions of respective components, are not absolute, but relative. When the respective components are arranged as shown in the drawings, these directional expressions are appropriate, but when the positions of the respective components in the drawings are changed, these directional expressions are also changed accordingly. Further, in the coordinate system shown in the drawings, the X direction corresponds to the longitudinal direction of the vehicle (i.e., the front-rear direction), the Y direction corresponds to the lateral direction of the vehicle (i.e., the left-right direction), and the Z direction corresponds to the vertical direction. It is to be understood that the attached drawings are not only used for explanation and illustration of the present invention, but also contribute to the definition of the present invention as necessary.

Preferred embodiments of the invention are described below with the aid of the figures. As mentioned previously, the present invention actually improves the connection of the ceiling lining to the skylight frame. The skylight frame, which surrounds and supports the skylight glass, is typically made of metal and plastic materials and includes a transverse front frame, a transverse rear frame, and a pair of left and right longitudinal rails. Headliners for concealing the peripheral structure of a skylight are typically made of a plastic material and may preferably include metal reinforcements to add mechanical strength. The roof lining is provided with a roof opening corresponding to the skylight glass and a plurality of positioning connecting parts arranged circumferentially around the roof opening, namely, parts for assembling connecting pieces to be connected to the skylight frame on the roof lining. For example, approximately fourteen to sixteen positioning connection portions are provided on the ceiling liner, respectively disposed on the front, rear, left, and right sides of the ceiling opening, to connect the ceiling liner to the front frame, the rear frame, and the left and right longitudinal rails, respectively. In the shown figures, the connecting element 1 is a connecting element for connecting the headliner to the longitudinal guide rail 3, as can be seen with reference to the coordinate system in each figure. For the connection of the headliner to the front or rear frame, the X-direction and the Y-direction have to be interchanged with one another compared to the coordinate system in the drawing, and the shape and configuration of the components are substantially identical and therefore not described or illustrated.

Fig. 1 to 8 show a first embodiment of a connection piece 1 according to the invention.

Referring to fig. 1 to 3, a connector 1 according to the present invention is an elastic connector made of, for example, POM (polyoxymethylene) material, which mainly includes a base plate 11 extending in an XY plane and a sunroof connecting portion and a ceiling connecting portion protruding from both sides of the base plate 11, respectively. More specifically, the base plate 11 has a top surface 111 and a bottom surface 112 opposite to each other, the sunroof connecting portion protruding from the top surface 111 for insertion and snapping to the longitudinal rails 3, and the ceiling connecting portion protruding from the bottom surface 112 for insertion and snapping to the positioning connecting portion 2 on the ceiling liner.

Referring to fig. 1 to 3, the ceiling connection includes a pair of resilient cantilevers 12 protruding from a bottom surface 112 of a base plate 11, the pair of resilient cantilevers 12 being arranged symmetrically with respect to a YZ mid-plane perpendicular to the base plate 11, each resilient cantilever 12 including a first section 121 protruding from the bottom surface 112 and a second section 122 extending from the first section 121 (preferably from an extended end of the first section 121) in a curved manner toward the bottom surface 112 for snapping-in with a positioning connection 2 on the ceiling lining. In this embodiment, the first sections 121 of the pair of elastic cantilevers 12 extend away from the bottom surface 112, in which case the bending angle between the first section 121 and the second section 122 of each elastic cantilever 12 is generally equal to or greater than 100 °. It is also preferred that the ceiling connection further comprises a cantilever reinforcement 13 arranged between the pair of resilient cantilevers 12, the cantilever reinforcement 13 protruding from the bottom surface 112 and connecting the first sections 121 of the pair of resilient cantilevers 12 for avoiding resilient contraction of the pair of resilient cantilevers 12 during manufacturing, causing a design mismatch. In addition, the cantilevered reinforcement 13 may also cooperate with the locating connection 2 of the headliner to provide an indication of a successful snap-fit (i.e., fit-in-place), as will be described further below.

Referring to fig. 4, the positioning connection portion 2 on the ceiling lining includes a snap groove 21 extending in the Y direction and configured to be snapped with the pair of elastic cantilevers 12, and the snap groove 21 includes a snap portion 22 configured to be interposed between the base plate 11 and the second section 122 of the pair of elastic cantilevers 12. When the connector 1 is to be detachably assembled to the positioning connection portion 2 of the ceiling lining, the second section 122 of the pair of elastic cantilevers 12 is to be inserted from the opening end portion along the Y direction and clamped into the clamping groove 21, so that the top surface of the clamping portion 22 is tightly abutted against the bottom surface 112 of the base plate 11, and the bottom surface of the clamping portion 22 is tightly abutted against the second section 122 of the pair of elastic cantilevers 12. Referring to fig. 5, after the clamping is completed, since the second section 122 has a specific shape bent toward the bottom surface 112, there is no gap between the clamping portion 22 and the bottom surface 112 and the second section 122, and thus no collision noise is generated when the vehicle travels or vibrates. Preferably, referring to fig. 4, 6 and 7, each positioning connection part 2 further includes a stopper 23 and an indication block 24, the stopper 23 is disposed at the top surface end of the snap-in part 22 to block the base plate 11 to perform a stopper function when the connection member 1 is assembled in place in the Y direction, and the indication block 24 protrudes from the bottom middle position of the snap-in groove 21 to cooperate with the cantilever reinforcement 13 and indicate that the connection member 1 is assembled in place, that is, during the insertion of the second sections 122 of the pair of elastic cantilevers 12 into the snap-in groove 21 in the Y direction, as the cantilever reinforcement 13 goes over the indication block 24 and the resultant rattling sound is heard, the positioning connection part 2 of the ceiling lining is successfully snapped into the ceiling connection part of the connection member 1.

It will be appreciated that the connector 1 can be adapted to other types of headliners as well. For example, fig. 8 shows a metal ceiling lining whose locating connection 2 likewise comprises a snap-in connection 22 configured for being tightly clamped between the base plate 11 and the second sections 122 of the pair of elastic cantilevers 12 for the fitting of the connecting element 1. It can be seen that the connection element 1 has good adaptability and can be widely used in various types of roof structures.

Referring to fig. 1 to 3, the sunroof connecting portion includes a catching head protruding from a top surface 111 of the base plate 11. In the embodiment shown, the clamping head comprises an intermediate support plate 14 projecting perpendicularly in the XZ plane from a middle position of the top surface 111 and a pair of elastic wing portions 15 extending from the intermediate support plate 14 and symmetrically arranged on either side of the intermediate support plate 14, the pair of elastic wing portions 15 extending from the top of the intermediate support plate 14 at a downward angle to the intermediate support plate 14 so as to be elastically compressible towards the intermediate support plate 14, and the free end of each elastic wing portion 15 forming a clamping end 151 configured for clamping with the longitudinal rail 3. Note that, in this embodiment, when the link 1 is inserted into or pulled out from the longitudinal rail 3 in the Z direction, the pair of elastic wing portions 15 are elastically deformed in the YZ plane, and the pair of elastic cantilevers 12 are elastically deformed in the XZ plane, and therefore, the plane along which the elastic wing portions 15 are elastically deformed is perpendicular to the plane along which the elastic cantilevers 12 are elastically deformed, which makes it possible to prevent the link 1 from being twisted. Preferably, the skylight connecting portion further includes a pair of positioning blocks 16 protruding from the top surface 111 and extending along the X direction, and the pair of positioning blocks 16 are symmetrically arranged at both sides of the clamping head portion adjacent to the edge of the base plate 11 for contacting the longitudinal rail 3 when the clamping head portion is inserted and clamped in the longitudinal rail 3. It is also preferable that the sunroof connecting portion further includes a pair of side walls 17 projecting perpendicularly from the top surface 111 in the YZ plane on both sides of the intermediate support plate 14, each side wall 17 including a guide slope 18 configured to guide the pair of elastic wings 15 to be inserted into and pulled out from the longitudinal rail 3, in the illustrated embodiment, the pair of side walls 17 continuously extend between both ends of the intermediate support plate 14 in the X direction and the corresponding positioning block 16, and a portion of the top surface of each side wall 17 forms the guide slope 18.

Referring to fig. 6 and 7, each longitudinal rail 3 comprises a receiving slot 31 extending in the X-direction and configured to receive the snap head, which receiving slot 31 is formed at the bottom of the longitudinal rail 3 and comprises a pair of hooks 32 configured to snap with the snap end 151 of the snap head, the spacing between the hooks 32 forming an opening for inserting the snap head into the receiving slot 31. When the ceiling lining is to be fitted to the longitudinal guide rail 3, after the connecting piece 1 is fitted to the positioning connection 2 of the ceiling lining, the snap-in head of the connecting piece 1 is aligned with the opening of the receiving groove 31 of the longitudinal guide rail 3, and the ceiling lining fitting assembly with the connecting piece 1 is then pushed in the Z direction towards the longitudinal guide rail 3, whereupon the elastic wing part 15 of said snap-in head is elastically compressed towards the intermediate support plate 14 under the push of the hook part 32 until the entire snap-in head is fully inserted into the receiving groove 31 by means of the guide ramp 18, and the elastic wing part 15 elastically returns to bring the snap-in end 151 and the hook part 32 into tight snap-in engagement with each other. After the clamping is realized, the top surface of the positioning block 16 is tightly abutted against the hook part 32, which increases the contact area of the longitudinal guide rail 3 and the connecting piece 1, so that the stability of the assembly can be ensured, and the distortion of the ceiling lining and the connecting piece 1 can not be caused. As mentioned above, the ceiling lining is connected not only to the longitudinal guide rails 3 but also to the front and rear frames, thus ensuring that the ceiling lining is fixed in all directions from the roof frame without relative movement. When the headliner is to be removed from the longitudinal guide 3, the headliner assembly with the connecting element 1 is pulled out of the longitudinal guide 3 in the Z-direction until the entire snap-in head is completely released from the receiving groove 31 by means of the guide ramp 18. It should be noted that, thanks to the particular configuration of the elastic cantilevers 12, it is possible to ensure that the headliner (and in particular the positioning connection 2) is not damaged during disassembly, and that even with high extraction forces, only the connectors 1 are damaged, leaving the integrity of the headliner unaffected.

Fig. 9 and 10 show a second embodiment of a connection piece 1 according to the invention.

In this second embodiment, the configuration of the sunroof connecting portion of the connecting member 1 is identical to that of the first embodiment, and it is different from the first embodiment in that the pair of elastic cantilevers 12 of the sunroof connecting portion of the connecting member 1 have different configurations. Referring to fig. 9 and 10, the first section 121 of the pair of elastic cantilevers 12 extends from the bottom surface 112 perpendicularly to the bottom surface 112, and in this case, since the second section 122 of the pair of elastic cantilevers 12 has a bent configuration toward the bottom surface 112, a bent angle between the first section 121 and the second section 122 of each elastic cantilever 12 is thus less than 90 °. Furthermore, in this embodiment, because of the vertical configuration of the first section 121, the ceiling connection may not include a cantilevered reinforcement connecting the first sections 121 of the pair of resilient cantilevers 12, and the tab 13' protruding from the bottom surface 112 shown in the figures is only used to mate with the indicator block 24 of the positioning connection 2 of the ceiling lining to serve as an indication of a successful snap (i.e., fit in place).

Fig. 11 to 14 show a third embodiment of a connection piece 1 according to the invention.

In this third embodiment, the construction of the roof connection of the connecting piece 1 is exactly the same as in the first embodiment, which differs from the first embodiment in that the snap-in head of the roof connection of the connecting piece 1 has a different construction. Referring to fig. 11 to 14, the catching head includes an intermediate support plate 14 vertically protruding from a middle position of the top surface 111 in the XZ plane and a pair of elastic wing portions 15 extending from the intermediate support plate 14 and asymmetrically disposed at both sides of the intermediate support plate 14, the pair of elastic wing portions 15 extending from a top and both side edges 141 of the intermediate support plate 14 in a manner surrounding a center of the intermediate support plate 14 so as to be elastically compressible toward the intermediate support plate 14, and a bottom end of each elastic wing portion 15 forming a catching end 151 configured to catch with the receiving groove 31 of the longitudinal guide rail 3. The configuration of the receiving groove 31 of the longitudinal rail 3 and its hook 32 is the same as in the first embodiment, so it is understood that the same receiving groove 31 can be adapted to a connector 1 with different types of snap-in heads. Furthermore, it should also be understood that, although not shown, the skylight connecting part of the connecting piece 1 according to this third embodiment may also include a pair of positioning blocks protruding from the top surface 111 and symmetrically arranged on both sides of the catching head part to be closely abutted against the hook parts 32 of the receiving grooves 31 after catching is achieved. Similarly, although not shown, the sunroof connecting portion of the connecting member 1 according to the third embodiment may also include a pair of sidewalls protruding perpendicularly from the top surface 111 at both sides of the intermediate support plate 14, each of the sidewalls including a guide slope configured to guide the pair of elastic wing portions 15.

Fig. 15 to 18 show a fourth embodiment of a connection piece 1 according to the invention.

In this fourth embodiment, the configuration of the ceiling connection of the connecting piece 1 is exactly the same as in the first embodiment, which differs from the first embodiment in that the snap-in head of the roof connection of the connecting piece 1 has a different configuration. Referring to fig. 15 to 18, the clamping head comprises an intermediate support 14 'projecting perpendicularly from a central position of the top surface 111, the top of the intermediate support 14' being formed with a pair of projections 15 'projecting in the opposite direction of the direction X, and the bottom of the intermediate support 14' being formed with a pair of supporting cantilevers 19 also projecting in the opposite direction of the direction X, the free end of each supporting cantilever 19 forming a supporting end 191. In fact, in this fourth embodiment, the skylight frame (front frame, rear frame and longitudinal rails) includes a frame fitting 3 'attached to its bottom, by means of which frame fitting 3' the connector 1 connects the headliner to the skylight frame. More specifically, the frame assembly 3 ' comprises a receiving portion 33 configured to receive the intermediate support member 14 ' of the connector 1, the receiving portion 33 comprising a snap arm 34, the top and bottom of the snap arm 34 respectively abutting against the boss 15 ' and the support end 191 of the support cantilever 19 when the intermediate support member 14 ' of the connector 1 is inserted into the receiving portion 33 in the Z-direction to bring the connector 1 into snap engagement with the frame assembly 3 '.

The technical content and technical features of the present invention have been disclosed above, but it should be understood that various changes and modifications can be made to the concept disclosed above by those skilled in the art under the inventive concept of the present invention, and all fall within the scope of the present invention.
