Passenger car combined interior trim part air channel easy to remove and dismount and mounting method thereof

Abstract

A passenger car combined interior trim part air channel easy to remove and dismount comprises a car body and air channel interior trim forming part combined bodies (A and B). A is composed of an air channel forming part base body, an upper profile assembling space, a lower profile assembling space, an upper profile and a lower profile, wherein the upper profile assembling space and the lower profile assembling space belong to the air channel forming part base body, and the upper profile and the lower profile are connected with the air channel forming part base body. B is formed by connecting an advertising lamp box base body, an illuminant, a light reflecting plate, advertising paper, a panel and a lock. The passenger car combined interior trim part air channel is characterized in that the components are combined; the passenger car combined interior trim part air channel is more reliable in quality and convenient to mount and maintain, errors are easy to control, and the total cost is greatly lowered; an advertising lamp box is easy to remove and dismount and can be overall opened and closed; various different important needs of users with different needs for the advertising lamp box can be met.

Description

technical field [0001] The invention relates to the field of public transport interior decorations, in particular to an air duct for easily removable combined interior decorations of a passenger car and an installation method thereof. Background technique [0002] At present, the interior products of passenger car air ducts on the market are mostly products such as foaming, injection molding, and compression molding. For this kind of products, after the air duct molding is completed, according to the different functional requirements of users, assembly components are added, and an inspection frame is opened at the appropriate position of the air duct molding, and an air duct inspection door is installed, or an advertising light box is installed locally. . The disadvantages of this kind of products are: the error of installation is difficult to control, the efficiency is low, the cost is high, and the waste of resources is large, which often leads to poor overall coordinatio...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of products are: the error of installation is difficult to control, the efficiency is low, the cost is high, and the waste of resources is large, which often leads to poor overall coordination of air duct interior products; at the same time, due to the existence of inspection doors, continuous Installation, a waste of advertising light box space resources

[0003] The other is continuous advertising light box-type aluminum alloy air duct interior decoration. Although it solves the problem that the above-mentioned advertising light boxes cannot be installed continuously, the disadvantage is that there are more assembly components and there is no integral part as the installation reference. The welding error and the splicing error of the profiles will eventually be reflected in the finished air duct interior decoration, making it more difficult to control the profile error and lower the assembly efficiency; more advanced questions

[0004] There is also a recent one, which is "a combined structure of passenger car air duct interior decoration" with application number 201310450278.4. This product is a continuous advertising light box air duct interior decoration of PU foam air duct moldings. It adopts a three-layer structure and Although the double-shaft hinge and double-layer locking device have solved the above-mentioned shortcomings—the air duct light box door and the air duct inspection door cannot be installed overlappingly at the same position, but because the advertising light box door, the inspection door and the air duct are formed Parts, forming a more complex three-layer structure - the air duct light box door, the air duct inspection door, respectively through the double-shaft hinge, double-layer locking structure, and the air duct forming parts are linked, so they often vibrate with the moving body, resulting in Abnormal sound, after a certain mileage of the bus, it is difficult to guarantee the anti-vibration quality of the more complex three-layer structure during the driving of the bus; secondly, the production (installation) cost of the more complex three-layer structure is also quite high, and the waste of resources is large

[0005] In addition, the above-mentioned continuous advertising light box-type aluminum alloy air duct interior decoration and the above-mentioned three-layer continuous advertising light box air duct interior decoration have two common shortcomings: the advertising light box cannot be opened and closed as a whole, and maintenance is quite troublesome; It is impossible to meet the different needs of users with different needs on the interior of the same model - continuous installation of advertising light boxes, partial installation of advertising light boxes, or no need to install advertising light boxes, etc.

[0006] In summary, the disadvantages of the related prior art can be summarized as follows: 1. The installation error is difficult to control, the efficiency is low, the cost is high (more than 40% higher overall), and the waste of resources is relatively large; Complicated three-layer structure, anti-vibration quality when the bus is running; 3. Advertising light boxes cannot be opened and closed as a whole, and it is not easy to remove, maintenance is quite troublesome, and they cannot be used on the interior of the same model to meet different needs Various different needs of users for the above-mentioned very important advertising light boxes
