Background technique

Waterproof covers are commonly used to protect the interior compartment of a vehicle from ingress of external elements, such as water, wind, and dust, which can damage or destroy vehicle fascia and degrade the interior environment of the vehicle. In particular, it is known to use flashings to seal around openings in the inner door panel of a vehicle, thereby protecting the vehicle trim attached to the inner door panel from water, dust and dust entering the hollow interior of the door.

Typically, the flashing is placed between the interior trim panel and the metal door skin forming the inner panel of the vehicle door. In order for a flashing to be an effective measure against external agents gaining access to the interior compartment of a vehicle, a reliable seal must be formed between the flashing and the inner door panel. Due to developments in design and manufacturing techniques, the inner panels that must form a reliable seal against the flashing can have multi-planar surfaces. Such surfaces are more difficult to seal.

Additionally, requirements for design strength and reliability require a repeatable and consistent assembly process. Thus, it becomes all the more important that the flashing is always installed over the critical formation so that the seal can be accurately positioned on that portion of the multi-planar surface of the door panel.

The fixing bracket 8 is made of a material more rigid than that of the waterproof cover 2 . For example, the fixing bracket 8 is at least partially made of metal or plastic. Since the fixing bracket 8 is more rigid than the flashing 2, the fixing bracket 8 is used to reinforce and stiffen the flashing 2 so that the flashing 2 remains sealed against the multi-planar surface 10 of the door panel 6, even after an extended service life. Even if exposed to extremes of temperature or wind pressure, or even to other environmental factors such as sea air, excessive sand or dust pollution.

A plurality of fixing receptacles 24 are disposed within fixing holes 26 in the door panel 6 and are shaped to receive and grip corresponding fixing plugs 28 . The fixing plugs 28 are configured to pass through the fixing hole 25 formed in the fixing bracket 8 , the perforated area 29 formed in the waterproof cover 2 and the perforated area 31 formed in the sealing member 11 , respectively. The fixed plug 28 and the fixed receptacle 24 may be threaded fasteners or snap-fit fasteners.

The first positioning pin 12 has a circular cross section, tapers towards its end 30 and has a fixing in the form of a barb or hook 32 towards its base. During installation of the flashing 2, the inclined face 33 of the barb facilitates the fit.

The second positioning pin 18 is shorter than the first positioning pin 12 , has a rectangular cross section and has a fixing in the form of a barb or hook 34 at its end. During installation of the flashing 2, the inclined face 35 of the barb facilitates the fit.

The waterproof cover 2 has a waterproof cover outer surface 38 facing the door panel 6 and a waterproof cover inner surface 40 facing the vehicle interior (not shown). The flashing 2 is shaped such that the flashing outer surface 38 mates with the multi-planar inner surface 42 of the door panel 6 . The flashing has locating holes 41 remote from the perforated areas 15 , 17 , 29 and configured to receive protruding elements 51 on the inner surface of the vehicle door.

The sealing member 11 is substantially L-shaped and has a sealant groove 43 and a sealant groove 45 at its two ends, respectively. The seal 11 has an outer sealing surface 44 facing the door panel 6 and an inner sealing surface 46 facing the vehicle interior. The seal 11 is deformable so that it conforms to the multi-planar portion of the door panel 6 .

Pre-assembly of waterproof cover

In one assembly method, the above-mentioned components are pre-assembled on the waterproof cover 2 first, and then the waterproof cover 2 is attached to the door panel 6 in a subsequent step. In this method, the first and second positioning pins 12 , 18 are pushed through the perforated areas 15 , 17 of the flashing 2 and the perforated areas 19 , 21 of the seal 11 by means of their respective tapered ends. The fixing bracket 8 and the sealing member 11 are then pressed together, thereby compressing the adhesive, sealant or tape between the fixing bracket 8 and the waterproof cover 2 and between the waterproof cover 2 and the sealing member 11 . When the adhesive or sealant has cured, the flashing assembly is ready to be attached to the door panel.

Watershield assembly attached to door panel

In this operation, a ring of sealant 37, adhesive or tape is first applied around the edge of the outer surface 38 of the flashing, the ring of sealant 37, adhesive or tape terminating in the sealant groove 43 of the seal 11 , Sealant groove 45. Then, the flashing assembly is provided to the door panel 6 such that the tapered end of the first positioning pin 12 is engaged in the first positioning hole 16 . Then, if necessary, the flashing assembly is rotated about the first positioning pin 12 until the protruding element 51 on the inner surface of the door engages the positioning hole 41 in the flashing. In this orientation, the flashing assembly is pushed towards the door panel 6 so that the shorter second locating pin 18 engages in the second locating hole 22 and subsequently engages the fixing member 32 with the first locating hole 16, the fixing member 34 engages with the second positioning hole 22, thus temporarily holding the waterproof cover assembly. An assembler or assembly robot can press around the edge of the flashing 2 to ensure a reliable seal between the flashing and the door panel.

Finally, the plug 28 passes through the fixing hole 25 in the fixing bracket 8 , the perforated area 29 in the waterproof cover 2 and the perforated area 31 in the seal 11 and enters the socket 24 fixed on the door panel 6 .
