Mounting structure of rear large handrail storage box cover unlocking assembly

Abstract

The invention discloses a mounting structure of a rear large handrail storage box cover unlocking assembly. The mounting structure comprises a box cover body and an unlocking assembly. The unlocking assembly comprises an unlocking buckling hand, a rotary shaft and a torsional spring. The unlocking buckling hand comprises a buckle hand body, a mounting part and a lock hook part, and the mounting part and the lock hook part are located on the two sides of the buckle hand body correspondingly. The surface of the inner side of the box cover body is concaved to from a buckle hand mounting sinking groove matched with the buckle hand body, and the buckle hand body is located in the buckle hand mounting sinking groove. The mounting part is inserted into the box cover body to be connected with therotary shaft. The torsional spring is elastically supported on the box cover body and the mounting part. According to the technical scheme, the passenger use feeling is good, mounting is easy, the performance is stable, and locking is reliable; and the mounting structure does not fail after long-term use, and is good in appearance effect and sufficient in advanced sense.

Description

technical field [0001] The invention relates to the technical field of car seat components, in particular to an installation structure of an unlocking assembly for a storage box cover of a large rear armrest. Background technique [0002] There is a storage box on the large rear armrest of some cars on the market, and the lid of the storage box is unlocked or locked by an unlocking mechanism. At present, most of the unlocking mechanism of the storage box cover of the large rear armrest adopts an exposed button or handle for unlocking operation, which affects the overall aesthetics of the large rear armrest. [0003] Therefore, a kind of rear row armrest storage box lid unlocking mechanism that adopts a hidden buckle (when the rear row large armrest storage box lid is in a closed state, from the outside, the buckle handle is invisible) has arisen at the historic moment in the market. Although the overall aesthetics of the large armrests in the rear row has been improved, the...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing lid unlocking mechanism that uses a hidden buckle basically uses steel wire as the elastic element, but when the steel wire is used as the elastic element, due to the influence of the structural characteristics of the steel wire, the elastic force value fluctuates greatly, which may easily lead to poor user experience.

[0005] 2. When installing the steel wire, it is necessary to rely on forced deformation to insert the two ends of the steel wire into the corresponding holes of the clasp. At the same time, in order to ensure the reliable installation of the steel wire, the length of the steel wire is usually designed to be much wider than the distance between the two holes of the clasp. It is very easy to install. Difficult, resulting in inefficient assembly of workshop workers

[0006] 3. The existing hidden handle is usually rotatably installed on the lower cover of the storage box lid through two independent shafts integrally formed at its left and right ends. Not only will the two shafts have coaxiality tolerance, but also There is an elastic steel wire installed near the rotating shaft. This area will always be under stress. The rotating shaft is easily deformed. The deformation of the rotating shaft means that the rotation center of the clasp will change, which may cause poor matching between the lock hook and the lock groove at the front of the storage box. Difficult to lock, due to the low strength of the plastic shaft, there may be a risk of failure after long-term use

[0007] 4. When the passenger operates the buckle, the moment around the axis of rotation is provided, and the force arm of the steel wire to provide the reverse force will change with the rotation of the buckle, resulting in a particularly large change in the force value during the passenger's operation of unlocking the buckle. Difference

[0008] 5. The entire unlocking button protrudes from the lower cover. After the box cover is opened, it not only looks very abrupt and unsightly, but also has the problem of exposed internal structure (usually the two ends of the steel wire are exposed), which has a poor sense of quality and poor appearance
