An improved structure at the end of luggage rack to overcome thermal expansion and contraction

Abstract

The invention belongs to the technical field of automobile accessories, and provides an end part improvement structure capable of overcoming thermal expansion and cold contraction of a baggage holder. The end part improvement structure comprises a baggage holder body, wherein the end part of the baggage holder body is provided with a transition fit body, the end part of the transition fit body is jacked to the right end surface of a metal plate to be flush with the right end surface of the metal plate after the baggage holder body is combined with the transition fit body, and the baggage holder body is arranged on the transition fit body and can slide along the upper flat surface of the transition fit body under the thermal expansion and cold contraction state of the baggage holder body. The end part improvement structure disclosed by the invention has the advantages that the structure is simple, the installing and the fixing are convenient, the baggage holder body is replaced by the transition fit body for jacking the end part of the transition fit body to the right end surface of the metal plate, so that the baggage holder has movable adjusting space during thermal expansion and cold contraction, the baggage holder just slides on the upper flat surface of the transition fit body during adjusting, the defect that the end part of an existing integral baggage holder body is jacked to the right end surface of the metal plate is overcome, and the appearance attractiveness of a whole baggage holder is ensured.

Description

technical field [0001] The invention belongs to the technical field of auto parts and relates to an improved structure at the end of a luggage rack to overcome thermal expansion and cold contraction. Background technique [0002] With the improvement of living standards, many SUVs and recreational vehicles are loved by young driving leisure groups, and driving for leisure travel or sports often has a lot of luggage in the car, and the interior space of the car itself is small. However, it cannot accommodate too many accompanying items, so installing a luggage rack on the roof helps to solve the shortcoming of being unable to accommodate too many accompanying items due to the small interior space of the car itself. The luggage rack on the roof of the car can not only be used to place Leisure sports goods, can also load goods, etc., such as figure 1 Shown is the roof rack structure of the prior art, where the roof fixing part 12 is directly located on the roof sheet metal, an...

[0002] With the improvement of living standards, many SUVs and recreational vehicles are loved by young driving leisure groups, and driving for leisure travel or sports often has a lot of luggage in the car, and the interior space of the car itself is small. However, it cannot accommodate too many accompanying items, so installing a luggage rack on the roof helps to solve the shortcoming of being unable to accommodate too many accompanying items due to the small interior space of the car itself. The luggage rack on the roof of the car can not only be used to place Leisure sports goods, can also load goods, etc., such as figure 1 Shown is the roof rack structure of the prior art, where the roof fixing part 12 is directly located on the roof sheet metal, and the entire luggage rack body 1 needs to be connected with the roof fixing part 12 during installation, as can be seen The luggage rack body 1 is a long and narrow structure of integral injection molding. The luggage rack body 1 itself will be subject to thermal expansion and contraction. The factors of thermal expansion and contraction will change significantly, so it will elongate or shorten along the X direction. When subjected to thermal expansion, the entire luggage rack body 1 It needs to stretch itself, and because the end of the luggage rack body 1 is pressed against the right end surface D of the sheet metal, it can no longer be stretched, so it will produce an arching phenomenon, so that when it is subjected to cold shrinkage, the entire luggage rack body 1 itself will be shortened , this will cause a gap between the end of the luggage rack body 1 and the right end surface D of the sheet metal, which seriously affects the appearance quality of the entire luggage rack, so it is necessary to improve the existing structure
