Description

Technical Field

[0001] The present invention relates generally to the field of motor vehicle body construction. More particularly, the present invention relates to a tailgate assembly and a vehicle including such a tailgate assembly. Background Art

[0002] The tailgate assembly of a vehicle includes a tailgate inner panel and a tailgate trim panel (for example, an upper tailgate trim panel and a lower tailgate trim panel) mounted on the inner side of the tailgate inner panel. The tailgate inner panel and the tailgate trim panel are usually connected by a buckle device. More specifically, the tailgate trim panel is usually integrally provided with a plurality of protruding buckle supports, and the tailgate trim panel is mounted to the tailgate inner panel by a plurality of buckles matching the buckle supports.

[0003] The defect of the existing tailgate assembly is that due to the manufacturing tolerance of the tailgate inner panel and the tailgate trim, vibration noise is generated between the buckle and the corresponding mounting hole on the tailgate inner panel. In addition, due to this manufacturing tolerance, the gap between the edge of the tailgate trim and the rear windshield is difficult to control. If the gap is too small, vibration noise will be generated due to the collision between the tailgate trim and the rear windshield when the vehicle is running. If the gap is too large, the internal parts may be exposed when looking inward from the rear of the vehicle, affecting the appearance of the vehicle. Summary of the invention

[0004] The object of the present invention is to provide a tailgate assembly of a vehicle to avoid vibration noise of the tailgate when the vehicle is running and ensure a good appearance effect of the rear side of the vehicle.

[0030] A preferred embodiment of the present invention is described below with reference to the accompanying drawings.

[0031] like Figure 1A , Figure 1B , Figure 2A and Figure 2B As shown, the tailgate assembly of the vehicle according to the present invention comprises a tailgate inner panel 10, a rear windshield 20 mounted to the tailgate inner panel 10, and at least one tailgate trim panel, such as the first tailgate trim panel 30 and the second tailgate trim panel 40 shown. More specifically, the tailgate inner panel 10 is provided with a glass opening 11 for mounting the rear windshield 20, a first mounting portion 12 located above the glass opening 11, and a second mounting portion 13 located below the glass opening 11, a plurality of first clipping portions 121 preferably evenly distributed are provided on the inner side of the first mounting portion 12, and a plurality of second clipping portions 131 preferably evenly distributed are provided on the inner side of the second mounting portion 13. A plurality of first clipping supports 31 facing the first clipping portions 121 are provided on the outer side of the first tailgate trim panel 30, so as to be mounted to the inner side of the tailgate inner panel 10 through a plurality of clips 50 passing through the first clipping supports 31 and the corresponding first clipping portions 121. The second tailgate trim panel 40 is provided with a plurality of second buckle supports 41 facing the second buckle portions 131 on the outer side thereof, so as to be mounted to the inner side of the tailgate inner panel 10 by a plurality of buckles 50 passing through the second buckle supports 41 and the corresponding second buckle portions 131 .

[0032] like FIG. 3A to FIG. 3CAs shown, each first clamping portion 121 of the tailgate inner panel 10 includes a first clamping hole 1211 and a first clamping wall 1212 surrounding the first clamping hole 1211. Each first clamping support 31 of the first tailgate trim 30 defines a first clamping slot 311 and includes a first top wall 312, which faces the corresponding first clamping hole 1211 and is provided with a first opening 3121. Each buckle 50 includes a base 51, a clamping joint 55, a clamping bottom 53, a spring 56 and a boss 57. The base 51 is abutted to the first top wall 312 between the first top wall 312 and the corresponding first clamping wall 1212. The clamping joint 55 is connected to the base 51 through the first connecting portion 54 passing through the first clamping hole 1211, and is clamped to the first clamping wall 1212. The clamping bottom 53 is connected to the base 51 through the second connecting portion 52 passing through the first opening 3121, and is clamped to the first clamping groove 311. The spring piece 56 extends from the first connecting portion 54 between the first top wall 312 and the first clamping wall 1212, and abuts against the first clamping wall 1212. The boss 57 extends from the first connecting portion 54 between the spring piece 56 and the first clamping wall 1212, and is spaced apart from the first clamping wall 1212. The boss 57 can abut against the first clamping wall 1212 when the buckle 50 is installed toward the tailgate inner panel 10, so as to protect the spring piece 56 and prevent the spring piece 56 from being damaged due to excessive deformation. Thus, the first buckle support 31 is connected to the inner side of the tailgate inner panel 10 through the buckle 50 passing through the first top wall 312 and the corresponding first clamping wall 1212.

[0033] Similarly, if FIG. 4A to FIG. 4CAs shown, each second clamping portion 131 of the tailgate inner panel 10 includes a second clamping hole 1311 and a second clamping wall 1312 surrounding the second clamping hole 1311. Each second clamping support 41 of the second tailgate trim 40 defines a second clamping slot 411 and includes a second top wall 412, which faces the corresponding second clamping hole 1311 and is provided with a second opening 4121. The base 51 of the clamp 50 abuts against the second top wall 412 between the second top wall 412 and the corresponding second clamping wall 1312. The clamping head 55 is connected to the base 51 by the first connecting portion 54 passing through the second clamping hole 1311, and is clamped to the second clamping wall 1312. The clamping bottom 53 is connected to the base 51 by the second connecting portion 52 passing through the second opening 4121, and is clamped to the second clamping slot 411. The spring piece 56 extends from the first connection portion 54 between the second top wall 412 and the second clamping wall 1312, and abuts against the second clamping wall 1312. The boss 57 extends from the first connection portion 54 between the spring piece 56 and the second clamping wall 1312, and is spaced apart from the second clamping wall 1312. The boss 57 can abut against the second clamping wall 1312 when the buckle 50 is installed toward the tailgate inner panel 10, so as to protect the spring piece 56 and prevent the spring piece 56 from being damaged due to excessive deformation. Thus, the second buckle support 41 is connected to the inner side of the tailgate inner panel 10 through the buckle 50 passing through the second top wall 412 and the corresponding second clamping wall 1312.

[0034] It is understood that the buckle 50 for mounting the first tailgate trim 30 and the buckle 50 for mounting the second tailgate trim 40 may have the same size or different sizes according to the actual installation strength requirements, and the present invention does not limit this. In addition, it is also understood that the spacing G2 between the boss 57 of the buckle 50 and the first clamping wall 1212 defines the pre-tightening amount of the buckle 50 in the first tailgate trim 30, and the spacing G4 between the boss 57 of the buckle 50 and the second clamping wall 1312 defines the pre-tightening amount of the buckle 50 in the second tailgate trim 40. For example, the spacing G2 between the boss 57 of the buckle 50 and the first clamping wall 1212 is preferably not less than 0.5 mm, and the spacing G4 between the boss 57 of the buckle 50 and the second clamping wall 1312 is preferably not less than 0.7 mm. The design of the present invention with a relatively large pre-tightening amount can absorb manufacturing tolerances and reduce vibration noise between the buckle 50 and the first engaging hole 1211 or the second engaging hole 1311 of the tailgate inner panel 10 .

[0035] like Figure 1B , Figure 2A , Figure 3A and Figure 3CAs shown, at least one of the plurality of first snap supports 31 of the first tailgate trim 30 that is adjacent to the rear windshield 20 is provided with a first support rib 32. More specifically, the upper edge 21 of the rear windshield 20 is connected to the lower edge 122 of the first mounting portion 12 of the tailgate inner panel 10, and the first tailgate trim 30 includes a plurality of first edge snap supports 31a that are adjacent to the upper edge 21 of the rear windshield 20 and are uniformly distributed along a straight line (i.e., substantially along the Y direction) parallel to the upper edge 21, such as the six first edge snap supports 31a shown, and each first edge snap support 31a is provided with a first support rib 32 that is preferably integrally formed on the first edge snap support 31a. The first supporting rib 32 protrudes from the first top wall 312 of the first edge snap support 31a toward the first snap wall 1212 of the corresponding first edge snap portion 121a of the tailgate inner panel 10 and abuts against the first snap wall 1212, so as to control the gap G1 between the edge 33 (adjacent to the rear windshield 20) of the first tailgate trim 30 and the rear windshield 20, so that the gap G1 remains uniform along the Y direction, thereby avoiding vibration noise caused by the collision between the first tailgate trim 30 and the rear windshield 20, and avoiding the situation where internal parts are exposed when looking inward from the rear of the vehicle due to the gap G1 being too large.

[0036] like Figure 1B , Figure 2B , FIG. 4A to FIG. 4C As shown, at least one of the plurality of second snap supports 41 of the second tailgate trim 40 that is adjacent to the rear windshield 20 is provided with a second support rib 42. More specifically, the lower edge 22 of the rear windshield 20 is connected to the upper edge 132 of the second mounting portion 13 of the tailgate inner panel 10, and the second tailgate trim 40 includes a plurality of second edge snap supports 41a that are adjacent to the lower edge 22 of the rear windshield 20 and are uniformly distributed along a straight line (i.e., substantially along the Y direction) parallel to the lower edge 22, such as the six second edge snap supports 41a shown, and each second edge snap support 41a is provided with a second support rib 42 that is preferably integrally formed on the second edge snap support 41a. The second supporting rib 42 protrudes from the second top wall 412 of the second edge snap support 41a toward the second snap wall 1312 of the corresponding second edge snap portion 131a of the tailgate inner panel 10 and abuts against the second snap wall 1312 to control the gap G3 between the edge 43 (adjacent to the rear windshield 20) of the second tailgate trim 40 and the rear windshield 20, so that the gap G3 remains uniform along the Y direction, thereby avoiding vibration noise caused by the collision between the second tailgate trim 40 and the rear windshield 20, and avoiding the situation where internal parts are exposed when looking inward from the rear of the vehicle due to the gap G3 being too large.

[0037] The technical content and technical features of the present invention have been disclosed above. However, it can be understood that under the creative ideas of the present invention, technicians in this field can make various changes and improvements to the above-disclosed concepts, but all belong to the protection scope of the present invention.
