Description

Fiber-woven reinforced composite thermoplastic material reinforced automobile plastic tail door

Technical Field

The utility model relates to an automobile plastic tail gate especially relates to an automobile plastic tail gate that reinforcing composite thermoplastic material reinforcing is woven to fibre.

Background

The application of car plastics tail-gate is more and more extensive, because the requirement of lightweight, the plastics material intensity that adopts is limited, and some connection structure positions at car plastics tail-gate require higher intensity, for example at the corner of opening hinge connection position and rear windshield of tail-gate, these positions need bear great stress, consequently adopt single material to mould plastics the plastics tail-gate and be difficult to accord with structural requirement. Therefore, the hinge structure is reinforced by a metal part through a glue bonding or riveting process, two problems are easily caused, firstly, the metal part is adopted as a structural part, the overall weight reduction effect of the plastic tail door is influenced, the metal part and the plastic tail door are easy to combine, the bonding process can be degummed, the riveting process needs to be added with riveting points, but the hinge structure and the corner position space are limited, and the riveting is inconvenient.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned prior art drawbacks, the task of the present invention is to provide a fiber-woven reinforced composite thermoplastic material reinforced plastic tail gate for an automobile, which solves the problem of structural reinforcement of the injection molded plastic tail gate at the hinge connection position and the corner position of the rear windshield.

The utility model discloses technical scheme is such: the utility model provides an automobile plastic tail-gate that fibre woven reinforcement composite thermoplastic material reinforcing, includes the plastics tail-gate body that forms of moulding plastics by the thermoplastic material, the dorsal part of plastics tail-gate body is located hinge joint position and the lower angular position of rear windshield and is equipped with the enhancement layer of fibre woven reinforcement composite thermoplastic material, the dorsal part of enhancement layer and the dorsal part of plastics tail-gate body does not set up the part of enhancement layer is equipped with the strengthening rib of moulding plastics, the enhancement layer with plastics tail-gate body and the strengthening rib of moulding plastics are through using the enhancement layer carries out the inserts process of moulding plastics and connects as the embedding piece.

Furthermore, the enhancement layer at the hinge connection position is at least provided with a hinge connection hole and a tail gate wiring harness hole.

Further, the plastics tail-gate body is equipped with the rear windshield opening, the strengthening rib of moulding plastics include by rear windshield opening's border profile to a plurality of main muscle and at least one edge that the border profile of plastics tail-gate body extends the brace rod that rear windshield opening's border profile extended.

Further, the support rib is connected with the main rib.

Further, the reinforcement layer is covered by the edge profile of the rear windshield opening to the edge profile of the plastic tailgate body.

Compared with the prior art, the utility model the advantage lie in:

the fiber woven reinforced composite thermoplastic material replaces a metal part and is in an integral injection molding structure with the tail gate, the reinforcing layer is arranged between the plastic tail gate body and the reinforcing rib, the weight of the tail gate can be reduced, the reliable connection between the reinforcing layer and the plastic tail gate body is met, the performance requirement of the tail gate is met, the bonding or riveting process is saved, the structure can be completed only by one-step injection molding, and the structure at the hinge is simplified.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1 to 3, the plastic tailgate of the fiber-woven reinforced composite thermoplastic material reinforced automobile according to the present embodiment includes a plastic tailgate body 1 formed by injection molding a thermoplastic material, wherein a rear windshield opening 1a is formed in an upper portion of the plastic tailgate body 1, and a circle of frame 1b surrounds the rear windshield opening 1 a. The frame 1b is used for being mounted and connected with a rear windshield. The hinge connection positions 2 are located at the upper left corner and the upper right corner of the rear windshield opening 1a, namely the left side vertex angle and the right side vertex angle of the frame 1b, and are provided with three hinge connection holes 3 and automobile tail door wiring harness holes 4.

The rear side (the side covering the exterior trim) of the plastic tailgate body 1 is provided with a reinforcement layer 6 of a fiber-woven reinforced composite thermoplastic material at the hinge connection position 2 and at the lower corner position 5 of the rear windshield. The reinforcement layer 6 at the hinge connection location 2 is also perforated to correspond to the hinge connection hole 3 and the tailgate strand hole 4. The lower corner position of the rear windshield is the position of a first concave folding angle 1c extending from the middle lower parts of the two sides of the frame 1b to the lower part of the side edge of the plastic tail gate body 1. The injection-molded reinforcing ribs 7 are disposed on the back side of the reinforcing layer 6 and the portion of the back side of the plastic tailgate body 1 where the reinforcing layer 6 is not disposed, so as to form a three-layer structure, as shown in fig. 3, the reinforcing layer 6 is disposed between the plastic tailgate body 1 and the injection-molded reinforcing ribs 7. The reinforcement layer 6 is covered by the edge profile 1d of the rear windshield opening 1a to the edge profile 1e of the plastic tailgate body 1. In this embodiment, the plastic tailgate body 1 and the injection-molded reinforcing rib 7 are PP-LGF40, the reinforcing layer 6 is a fiber-woven reinforced composite material made of PP, the plastic tailgate body 1 and the injection-molded reinforcing rib 7 are the same as the thermoplastic base material of the reinforcing layer 6, and the reinforcing layer 6 is connected with the plastic tailgate body 1 and the injection-molded reinforcing rib 7 by using the reinforcing layer 6 as an insert through an insert injection molding process. In order to ensure the reliable strength of the plastic tailgate 1 at the position of the frame 1b, the injection-molded reinforcing rib 6 comprises a plurality of main ribs 7a extending from the edge profile 1d of the rear windshield opening 1a to the edge profile 1e of the plastic tailgate body 1 and at least one supporting rib 7b extending along the edge profile 1d of the rear windshield opening 1 a. The support ribs 7b are connected with the main ribs 7a, longitudinal and transverse structural reinforcement is provided for the frame 1b, the main ribs 7a provide strength between the inner edge and the outer edge for the frame 1b, and the main ribs 7a are further reinforced by the support ribs 7 b.
