Description

Cab side cabinet mounting structure

Technical Field

The utility model belongs to the technical field of the rail transit vehicle, especially, relate to a cab side cabinet mounting structure.

Background

Along with the improvement of the speed of rail transit products and the improvement of the requirements of users and drivers on the quality of the operating environment of the cab, the requirements on the curved surface shape and the color of interior decoration products of the cab are more and more complex and various, and the requirements on the installation of products of the cab are more and more high.

Traditional cab side cabinet adopts glass steel integral forming structure, perhaps outside visible region packs the nonmetal easy formed part of one deck, and these two kinds of structures have following defect: firstly, due to errors in the manufacturing and installation processes, when the side cabinet and the cab side wall are installed, the installation and the matching are difficult, the molded lines of the side cabinet and the cab side wall cannot be adjusted in place, and no solution exists at present; secondly, the side cabinet can not be sealed.

In order to solve the above problems, it is a common practice to glue and seal the side cabinet and the side wall of the cab, and the matching position of the bottom of the side cabinet and the floor. The scheme has the defects that glue and side walls, glue and a floor cannot be uniform in color and attractive in appearance, and the quality of a cab is influenced; meanwhile, the glue is long in curing time, the operation efficiency is influenced, and the glue is easy to crack and even fall off due to the shrinkage of the glue and the vibration during operation, so that the effect is poor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a cab side cabinet mounting structure who promotes cab quality.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a cab side cabinet mounting structure, includes side wall, floor and side cabinet, the side cabinet includes the skeleton body and locates the apron at skeleton body top, the skeleton body is installed on the floor, the bottom of side wall is equipped with the folded plate that extends towards the cab, the apron is passed through the sealing member towards the one end of side wall and is set up in on the folded plate.

And the side cabinet cover plate is provided with a color separation groove. One end of the color separation groove is preferably painted with the same color as the side wall of the cab, so that the color transition between the side cabinet of the cab and the side wall of the cab is ensured. Further, the preferred paint is a repairable in the field, which allows for the in-situ preparation of the linetype of the sideboard lid edge.

The first special-shaped through hole, the second special-shaped through hole and the third special-shaped through hole are waist-shaped holes or rectangular holes.

When the deviation between the profile line and the distance between the side cabinet of the cab and the side wall of the cab is large, the framework body is roughly adjusted in large size through the special-shaped holes in the framework body, and the position of the sealing piece and the side wall of the cab is used for positioning; the side cabinet cover plate is finely adjusted in small size through the special-shaped holes in the supporting blocks, and the side cabinet overlapping edges of the cab are matched with the side wall distance and the profile of the cab to be positioned;

when the deviation between the side cabinet of the cab and the side wall of the cab is small, fine adjustment of small size is carried out on the side cabinet cover plate through the special-shaped hole in the supporting block, and positioning is carried out by matching the distance between the folded edge of the side cabinet of the cab and the side wall of the cab and the molded line.

The floor cloth is laid on the floor, the skirting line is laid on the lower portion of the outer side face of the framework body, the floor cloth extends to the position between the framework body and the skirting line, the floor cloth and the framework body are connected through a third fastener.

The outer wall surface of the skirting line is provided with a groove, and one end of the third fastener is accommodated in the groove.

The third fastener is preferably a screw, in order to reduce weight and ensure that the screw is in a sight blind area so as to improve the quality of the cab, the skirting line is positioned below the cabinet door and adopts a concave section with a hollow section, and the screw is arranged in the groove.

In order to replace sealant and ensure the sealing effect between the side cabinet of the cab and the floor, the floor cloth is extended between the skirting line and the inner framework. The structure cancels sealant, and ensures the color uniformity of the cab, thereby ensuring the quality of the cab.

Compared with the prior art, the utility model has the advantages of:

1. through adopting the hem overlap joint and installing the sealed piece of L type and seal to and adopt the floor cloth to extend to skeleton body upper portion, and adopt skirting line and fastener extrusion fastening's mode, thereby replaced original mode of gluing sealedly, guaranteed simultaneously that the part colour of cooperation department is unified, promoted the driver's cabin quality.

2. The following two-stage regulation was used: the large-size primary adjustment is carried out through the waist-shaped hole of the inner framework, the small-size precise adjustment is carried out on the gap and the molded line of the cab side cabinet cover plate and the cab side wall matching position through the support frame waist-shaped hole, and the sealing block and the cab side cabinet cover plate are adopted for positioning. Two kinds of regulation combine together, and the adjustment difficulty when having solved cab side cabinet installation, it is inhomogeneous with cab side wall fit clearance, the uneven problem of line type.
