Combined butt-joint connecting device for vehicle-mounted baggage carrier

Abstract

The invention discloses a combined butt-joint connecting device for a vehicle-mounted baggage carrier. The combined butt-joint connecting device for the vehicle-mounted baggage carrier comprises a baggage carrier bearing beam (2), an end cover decoration plate (3) and an end cover base (6); the bottom of the end cover decoration plate is symmetrically and inwards narrowed to form a predeformationstructure, and the end cover base can be in interference clamping connection with the narrowed end cover decoration plate to generate first-time self-adaptive correction on the external profile of theend cover decoration plate; a bearing beam installing hole (10) is formed in the baggage carrier bearing beam, a cylindrical pin (11) is arranged in the end cover base, and the cylindrical pin and the center of the bearing beam installing hole are installed in a staggered mode; and the end cover decoration plate is provided with a plurality of wedge-shaped ribs (13), the inner wall of the baggagecarrier bearing beam can extrude the wedge-shaped ribs (13) and be in interference assembling with the end cover decoration plate, and the baggage carrier bearing beam generates second-time self-adaptive correction on the profiles of the wedge-shaped ribs. According to the combined butt-joint connecting device for the vehicle-mounted baggage carrier, high-precision butt-joint connecting of the baggage carrier bearing beam and an end cover can be achieved, and the baggage carrier assembling technology difficulty is reduced.

Description

technical field [0001] The invention relates to a vehicle accessory, in particular to a combined docking device for a vehicle luggage rack. Background technique [0002] In order to improve the loading capacity of the vehicle, a vehicle-mounted luggage rack is installed on the roof of many vehicles. The vehicle-mounted luggage rack in the prior art is generally composed of a load-bearing part and a decorative part butted together. When the luggage rack is assembled in the actual vehicle, the requirements for the flatness of the load-bearing part and the decorative part of the luggage rack are very high, and the accuracy of ±0.2mm is usually required to meet the requirements for the safety performance of the luggage rack on the vehicle and avoid load-bearing on the vehicle. When there are safety hazards such as loose docking of the luggage rack, it can also meet the requirements of visual appearance. [0003] At present, in order to meet the load requirements, the vehicle-mo...

AI Technical Summary

Problems solved by technology

Although the end support can improve the bearing capacity and installation stability of the end cover, the tenon installation method between it and the longitudinal beam cannot meet the extremely high requirements for the connection reliability and flatness of the docking part of the luggage rack. certain security risks
