Abstract

In one or more embodiments, a vehicle frame joint assembly includes a first frame portion including an adaptor, a second frame portion defining a cavity to receive at least a portion of the adaptor, and a first adhesive layer positioned between the adaptor and the cavity when the first frame portion is connected to the second frame portion.

First claim

1 . A frame joint assembly of a vehicle, comprising:
a first frame portion including an adaptor including a first plastic material; a second frame portion defining a cavity including a second plastic material and to receive at least a portion of the adaptor; and a first adhesive layer positioned between the adaptor and the cavity when the first frame portion is connected to the second frame portion.

2 . The frame joint assembly of claim 1 , further comprising a second adhesive layer positioned between the first adhesive layer and the cavity, wherein the first adhesive layer differs in chemistry from the second adhesive layer.

3 . (canceled)

4 . The frame joint assembly of claim 1 , wherein the first adhesive layer includes two or more adhesive patches at least partially spaced apart from each other.

5 . The frame joint assembly of claim 4 , wherein the first adhesive layer includes first and second adhesive patches positioned along a circumferential direction of an outer surface of the adaptor.

6 . The frame joint assembly of claim 4 , wherein the first adhesive layer includes first and third adhesive patches positioned along an axial direction of the adaptor.

7 . The frame joint assembly of claim 1 , wherein the first adhesive layer includes an adhesive material with melting temperature no less than 100 degrees Celsius.

8 . The frame joint assembly of claim 1 , wherein one of the first and second frame portions is a sub-frame of the vehicle, and the at least a portion of the adaptor is received axially within the cavity along a vehicle height direction.

9 . The frame joint assembly of claim 1 , wherein the adaptor includes a core and a shell positioned between the cavity and the core in an axial direction along which the cavity extends.

10 . The frame joint assembly of claim 9 , wherein the core differs from the shell in material.

11 . The frame joint assembly of claim 9 , wherein the adaptor includes one or more intermediate layers positioned between the core and the shell.

12 . A method of forming a frame joint assembly in a vehicle, comprising:
positioning an adaptor of a first frame portion to be at least partially received within a cavity of a second frame portion, the adaptor and cavity respectively including first and second plastic materials; and positioning a first adhesive layer to be between the adaptor and the cavity.

13 . The method of claim 12 , further comprising positioning a second adhesive layer to be between the first adhesive layer and the cavity, wherein the first adhesive layer is applied to the adaptor and the second adhesive layer is applied to the cavity.

14 . (canceled)

15 . The method of claim 12 , wherein the first adhesive layer is positioned to form first and second adhesive patches at least partially spaced apart from each other along a first direction and third and fourth adhesive patches at least partially spaced apart from each other along a second direction different from the first direction.

16 . (canceled)

17 . The method of claim 12 , wherein the first adhesive layer is applied as a part of a pre-formed adhesive sandwich with removable backing sheets.

18 . A frame joint assembly of a vehicle, comprising:
a first frame portion including an adaptor including a first plastic material; a second frame portion defining a cavity including a second plastic material and to receive at least a portion of the adaptor; and first and second adhesive layers positioned between the adaptor and the cavity, the second adhesive layer being positioned between the first adhesive layer and the cavity and differing in chemistry from the first adhesive layer.

19 . The frame joint assembly of claim 18 , wherein at least one of the first and second adhesive layers includes two or more adhesive patches at least partially spaced apart from each other in a first direction, and another two or more adhesive patches at least partially spaced apart from each other in a second direction different from the first direction.

20 . (canceled)

21 . The frame joint assembly of claim 1 , wherein the first adhesive layer contacts both the adaptor and the cavity.

22 . The method of claim 12 , wherein the first adhesive layer is applied to contact both the adaptor and the cavity.

23 . The frame joint assembly of claim 18 , wherein the first adhesive layer contacts the adaptor and the second adhesive layer contacts the cavity.

24 . The frame joint assembly of claim 1 , wherein the first plastic material is at least partially present in an outer surface of the adaptor facing toward the cavity, and the second plastic material is at least partially present in an outer surface defining the cavity facing toward the adaptor.
