Problems solved by technology

The main defect of this structure: the fastening buckle of the top lining can only move 1mm in the buckle installation circular gap of the buckle seat, and the fastening buckle of the top lining can only move 0.2mm in the buckle assembly circular gap of the roof beam. mm, the tolerance is small, it is difficult to meet the superposition of the tolerance of the roof lining and the roof beam, resulting in problems such as the assembly damage of the roof lining and the depression of the roof lining surface. If the buckle fits in the round gap, it is easy to cause the separation of the fastening buckle of the top lining and the beam of the top cover, resulting in failure of the connection

Embodiment 1

[0025] figure 1 It is a schematic main view of a top liner fixing structure according to an embodiment of the present application. Such as figure 1 As shown, in a specific embodiment, the roof lining fixing structure may generally include a roof lining 1 , a roof beam 2 , and a roof lining fastening buckle 3 .

[0026] In detail, the upper part of the top lining 1 has a buckle installation part 1-1, and the upper part of the buckle installation part 1-1 is provided with a first assembly gap 1-2; the roof beam 2 is provided with a second assembly gap 2-1; The upper part of the lining fastening buckle 3 is detachably clamped to the second assembly gap 2-1, and the lower part of the top lining fastening buckle 3 is detachably clamped to the top first assembly gap 1-2; the top lining fastens The buckle 3 includes; the bottom plate 3-1 is horizontally arranged and inserted into the inside of the buckle installation part 1-1; the lower end of the vertical support bar 3-2 is integr...

Embodiment 2

[0034] Such as figure 1 As shown, in one embodiment, it includes the features defined in any of the above embodiments, and further and optionally. The roof lining fixing structure may also include a buckle seat 1-3, a side panel 1-4 and a rear panel 1-5.

[0035] In detail, the buckle seat 1-3 is located between the top lining 1 and the buckle installation part 1-1, the lower part of the buckle seat 1-3 is integrally formed with the top lining 1, and the upper part of the buckle seat 1-3 is connected with the buckle The installation part 1-1 is integrally formed, and the buckle seat 1-3 includes; the side panel 1-4 is arranged vertically and integrally formed with the top of the top lining 1; the rear panel 1-5 is arranged vertically and is integrated with the upper part of the top lining 1; The upper part of the top lining 1 is formed in one piece.

[0036] In this embodiment, the side panel 1-4 of the buckle seat 1-3 is a rectangular plate body, which is vertically arrange...

Embodiment 3

[0040] Such as figure 1 As shown, in one embodiment, it includes the features defined in any of the above embodiments, and further and optionally. The buckle installation part 1-1 may generally include a lower plate 1-6, an upper plate 1-7, and a gap 1-8.

[0041] In detail, the lower plate 1-6 is arranged horizontally and integrally constructed on the inner upper part of the buckle seat 1-3; the upper plate 1-7 is arranged horizontally and integrally constructed on the top of the buckle seat 1-3.

[0042] Among them, there is a gap 1-8 between the lower plate 1-6 and the upper plate 1-7, which is used for the bottom plate 3-1 to snap into the gap 1-8, and the first assembly gap 1-2 is opened in the upper plate 1-7. On the front side, the vertical support bar 3-2 is located in the first assembly gap 1-2, so that the top lining fastening buckle 3 and the top lining 1 are detachably snapped together.

[0043] In this embodiment, the lower plate 1-6 is a rectangular plate, adap...

Abstract

A top lining fixing structure comprises a top lining, the upper portion of the top lining is provided with a buckle installation part, and the upper portion of the buckle installation part is provided with a first assembly notch; the top cover cross beam is provided with a second assembly notch; the upper portion of the top lining fastening buckle is detachably clamped to the second assembly notch, and the lower portion of the top lining fastening buckle is detachably clamped to the top end first assembly notch. The top lining fastening buckle comprises a bottom plate and is inserted into the buckle mounting part; the lower ends of the vertical supporting strips are integrally formed in the middle of the upper surface of the bottom plate. The middle of the lower portion of the top plate and the upper ends of the vertical supporting strips are integrally formed, and the top plate is clamped into the second assembling notch. The width of the lower portion of the vertical supporting strip is smaller than the length of the first assembling notch, and the thickness of the top plate is smaller than the width of the second assembling notch, so that the tolerance between the lower portion of the vertical supporting strip and the first assembling notch is large, the tolerance between the top plate and the second assembling notch is large, tolerance superposition is conducted on the top lining and the top cover beam, and the top lining is not prone to damage after being assembled. Meanwhile, the top lining surface sinking problem is avoided.

Description

technical field [0001] The invention relates to the technical field of roof lining fixing, in particular to a roof lining fixing structure. Background technique [0002] The buckle seat of the existing top lining fixing structure is bonded to the back of the top lining by hot melt adhesive, the lower end of the top lining fastening buckle is assembled in the buckle installation circular opening of the buckle seat, and the top lining fastening buckle The upper end is snapped into the buckle assembly circular gap of the top cover beam. The main defect of this structure: the fastening buckle of the top lining can only move 1mm in the buckle installation circular gap of the buckle seat, and the fastening buckle of the top lining can only move 0.2mm in the buckle assembly circular gap of the roof beam. mm, the tolerance is small, it is difficult to meet the superposition of the tolerance of the roof lining and the roof beam, resulting in problems such as the assembly damage of t...
