Description

Technical Field

[0001] This utility model relates to the field of trunk lid technology, and in particular to a car trunk lid. Background Technology

[0002] Lightweight design is a crucial technology for improving the driving range of electric vehicles. Traditional sheet metal trunk lids or tailgates are heavy and have limited design options, while also involving numerous parts and complex manufacturing processes. PP composite material trunk lids or tailgates not only meet the requirements of appearance, performance, and limited design space for automotive trunk lids, but also reduce weight, satisfying lightweight design, dimensional matching, and production cycle requirements, enabling composite assembly. Furthermore, a novel structure is provided on the inner panel, effectively controlling the minimum thickness of the structural adhesive during internal and external bonding, ensuring the product's connection strength and sealing performance.

[0003] For some special shapes, such as sharp edges and twisted curved surfaces, traditional sheet metal luggage lids cannot be formed due to limitations in stamping angle and stamping equipment size, or the forming process is complex, costly, and results in a heavy product. Currently available products use an inner / outer panel bonding and pressing process as follows (e.g.) Figure 1 (As shown): The inner panel of the trunk lid is placed on the membrane, and a segmented structure supports the inner panel along the adhesive path. Structural adhesive is applied to the outer adhesive path. The outer panel of the trunk lid is pressed downwards in the pressing direction. Because the pressing depth cannot be accurately controlled in the pressing direction, the thickness of the structural adhesive cannot be effectively controlled and is determined by the factory's manufacturing capabilities. The thickness of the structural adhesive varies, and there can be an order of magnitude error in the thickness of the structural adhesive within the same product. An excessively thick structural adhesive layer may generate bubbles or shrinkage during curing, leading to internal stress and reducing bond strength. An excessively thin structural adhesive layer may not fully cover the bonding surface, resulting in insufficient bonding area, which also affects strength. Inconsistent thickness may lead to uneven stress distribution in different areas, making it prone to breakage at weak points. Furthermore, an excessively thin or broken adhesive layer will result in discontinuous sealing, and the sealing performance cannot be effectively controlled, leading to product defects and scrap.

[0004] Patent publication number CN109774437A discloses a lightweight all-plastic tailgate assembly, including an inner panel, a spoiler, an outer panel, a rear window glass, and windshield trim. The inner panel, spoiler, and outer panel are bonded together to form a single unit, with a sandwich-style adhesive structure between them. The inner panel, on the interior side, includes a U-shaped cavity for taillight mounting, a left main reinforcing beam, a right main reinforcing beam, a left secondary reinforcing beam, a right secondary reinforcing beam, a door lock mounting hole area, a left taillight maintenance hole area, a right taillight maintenance hole area, a left buffer block mounting position, and a right buffer block mounting position. However, this plastic tailgate assembly still suffers from the problem of uncontrollable thickness of the structural adhesive. Utility Model Content

[0051] Compared with the prior art, the present invention has the following advantages:

[0052] (1) The present invention provides adhesive-blocking ribs on both sides of the structural adhesive. During the bonding and pressing process, when the gap between the pressing surface and the pressed surface approaches the height of the adhesive-blocking ribs, the adhesive-blocking ribs will provide support to the pressing surface, thereby achieving a supporting effect and preventing the pressing surface from being pressed down further. This controls the gap between the pressing surface and the pressed surface to be no less than the height of the adhesive-blocking ribs, thereby effectively controlling the thickness of the structural adhesive and ensuring the connection strength and sealing of the product.

[0053] (2) In this utility model, structural adhesive is applied to the structural adhesive area surrounding the sealing surface area, hinge installation area, and buckle installation area. Structural adhesive is also applied between the outer panel flange and the inner panel flange, and adhesive-blocking ribs are set on both sides of the structural adhesive. This allows the thickness of the structural adhesive to be adjusted in the X and Z directions when the outer panel and inner panel of the luggage compartment lid are bonded and pressed together, so as to achieve accurate fitting in multiple directions and thus ensure the connection strength and sealing performance of the product.

[0054] (3) In this invention, structural adhesive is applied in a continuous interval between the structural adhesive area and the outer and inner panel flanges. Continuous application ensures uniform coverage of the base surface and forms an integral protective layer; while interval application targets the stress concentration area for local reinforcement and disperses the stress peak.

[0055] (4) The present invention makes variable wall thickness design for each area of ​​the inner panel of the luggage compartment lid so that it can meet the thickness requirements of different areas, thereby flexibly adjusting the height of the glue-blocking ribs and accurately controlling the connection strength and sealing between each connecting structure.

[0056] (5) The present invention installs the high brake light on the top of the inner and outer panels of the luggage compartment lid. The rest of the luggage compartment lid structure will not obstruct the high brake light, and the installation and removal of the high brake light is very convenient.

[0057] (6) This utility model connects the high brake light to the inner panel and outer panel of the luggage compartment lid through the high brake light installation structure, accurately controls the position coordinates of the high brake light in three-dimensional space, and ensures the positioning accuracy of its assembly with the inner panel and outer panel of the luggage compartment lid.

[0126] Example 1

[0127] A type of car trunk lid, such as Figure 2 and 3 As shown, it includes:

[0128] Outer panel of the suitcase lid 1;

[0129] The inner panel 2 of the luggage lid is fixed to the inside of the outer panel 1 of the luggage lid;

[0130] Hinge reinforcement plates 5 are provided on both sides of the inner panel 2 of the luggage compartment lid;

[0131] A locking reinforcement plate 6 is provided at the bottom of the inner panel 2 of the luggage compartment lid;

[0132] Structural adhesive 3 is disposed between the outer panel 1 and the inner panel 2 of the trunk lid and is used to connect the two.

[0133] And adhesive-blocking ribs 4 are provided on both sides of the structural adhesive 3.

[0134] In this embodiment, the outer panel 1 of the luggage lid is made of PP material, the inner panel 2 of the luggage lid is made of PP+LGF material, and the hinge reinforcement plate 5 and the latch reinforcement plate 6 are made of sheet metal.

[0135] In this embodiment, the structural adhesive 3 is PU structural adhesive, and the adhesive-blocking rib 4 is made of PP+LGF material.

[0136] In this embodiment, the height of the adhesive-blocking rib 4 is half the height of the structural adhesive 3.

[0137] In this embodiment, the inner panel 2 of the luggage compartment lid and the hinge reinforcing plate 5 are connected by the structural adhesive 3, and the structural adhesive 3 is provided with adhesive-blocking ribs 4 on both sides;

[0138] The inner panel 2 of the luggage compartment lid and the buckle reinforcement plate 6 are connected by the structural adhesive 3, and the structural adhesive 3 is provided with adhesive-blocking ribs 4 on both sides.

[0139] In this embodiment, as Figure 4 As shown, the inner panel 2 of the luggage compartment lid includes:

[0140] Internal structural region 21;

[0141] Hinge mounting areas 24 are provided on both sides of the internal structure area 21 and are used to mount the hinge reinforcement plate 5.

[0142] A latch mounting area 25 is provided at the bottom of the internal structure area 21 and is used to install the latch reinforcement plate 6.

[0143] A sealing surface region 22 that surrounds and seals the interior structural region 21, hinge mounting region 24, and latch mounting region 25.

[0144] And a structural adhesive area 23 surrounding the outer ring of the sealing surface area 22, the hinge mounting area 24, and the latch mounting area 25, for applying the structural adhesive 3.

[0145] In this embodiment, the structural adhesive 3 is applied continuously and intermittently within the structural adhesive region 23.

[0146] In this embodiment, the internal structural region 21 adopts a conventional structure in the art, which is not the focus of this utility model, and therefore will not be described in detail.

[0147] In this embodiment, the sealing surface area 22 is sealed using conventional techniques in the art, and a rubber sealing strip is used for sealing.

[0148] In this embodiment, as Figure 5 As shown, the luggage compartment lid outer panel 1 also includes an outer panel flange 12 that extends upward along the Z direction from its X-direction front end;

[0149] The inner panel 2 of the luggage compartment lid also includes an inner panel flange 26 that extends upward along the Z direction from its X-direction front end. The inner panel flange 26 is located at the front end of the outer panel flange 12 in the X direction.

[0150] In this embodiment, the outer panel flange 12 and the inner panel flange 26 are connected by the structural adhesive 3, and the structural adhesive 3 is provided with adhesive-blocking ribs 4 on both sides.

[0152] In this embodiment, when bonding with structural adhesive 3, the hinge reinforcement plate 5 and the latch reinforcement plate 6 are first bonded to the inner panel 2 of the luggage compartment lid, then the inner panel 2 of the luggage compartment lid and the outer panel 1 of the luggage compartment lid are bonded together, and finally a rubber sealing strip is used to seal the sealing surface area 22.

[0153] In this embodiment, when bonding the inner panel 2 and the outer panel 1 of the trunk lid, the structural adhesive area 23 is bonded first, followed by the outer panel flange 12 and the inner panel flange 26. This is because the structural adhesive area 23 is the main contact area between the inner panel 2 and the outer panel 1 of the trunk lid, bearing most of the load, such as vibrations from bumps and impacts from closing. Bonding the structural adhesive area 23 first ensures accurate positioning of the main structural surface and avoids interference with positioning accuracy during the operation of the outer panel flange 12 and the inner panel flange 26. During the bonding process, since adhesive-blocking ribs 4 are provided on both sides of the structural adhesive 3, they support the outer panel 1 of the trunk lid, preventing further downward pressure during the bonding and pressing process, thereby effectively controlling the thickness of the structural adhesive 3.

[0154] Example 2

[0155] This embodiment is based on Embodiment 1 and is mostly the same as Embodiment 1, except that the thickness of the internal structural area 21, sealing surface area 22, structural adhesive area 23, hinge mounting area 24, and latch mounting area 25 are different.
