Seat cushion lock for motorcycle

Abstract

The invention discloses a seat cushion lock for a motorcycle. The seat cushion lock comprises a lock body part structure and a locking part structure which are opposite to each other, wherein the lock body part structure is fixed on a covering member, and the locking part structure is fixed on a frame. The seat cushion lock is characterized in that a straightened flexible pull rope is arranged between the lock body part structure and the locking part structure; and when a lock core of the lock body part structure is rotated by a key, a lock rod of the locking part structure can be pulled by the flexible pull rope. According to the seat cushion lock, a mode of transmission action of force during locking / unlocking of the seat cushion lock of the motorcycle is changed, and the transmission of the force between the lock body part structure and the locking part structure is realized by virtue of connection of the flexible pull rope, so that the influence of mounting faults on assembly and use is avoided, the assembly difficulty is reduced, the assembly quality is improved, the assembly time is shortened, and the reliability of a final product is guaranteed.

Description

technical field [0001] The invention relates to a seat cushion lock structure of a curved beam motorcycle and a scooter. Background technique [0002] In current underbone motorcycles and scooters, a seat box is generally provided under the seat cushion for placing articles, one end of the seat cushion is hinged to the upper port of the seat cushion box and serves as a box cover, and a seat is provided at the other end of the seat cushion. The pad lock structure makes it easy to lock the seat box. [0003] The seat cushion lock structure of the existing curved beam motorcycle and scooter includes the seat cushion lock body and the seat cushion lock mechanism, and the seat cushion lock body and the seat cushion lock mechanism all form a hard connection in the form of a shaft, that is, in the assembly Usually, one end of the seat cushion locking mechanism is assembled on the frame outside the seat cushion box and covered by the cover of the vehicle body, and the connecting sh...

AI Technical Summary

Problems solved by technology

The disadvantage of this structure is: when assembling, the locking mechanism part is installed first, and then the lock body must pass through the pre-set mounting hole on the cover, resulting in relatively long shafts for the lock body and small manufacturing errors at the frame installation It will be enlarged; there are generally many connection points between the cover itself and the frame, and it is difficult to control the accuracy of the installation position

Therefore, there are often errors in the fit between the lock body and the mounting hole reserved for the cover during installation, resulting in problems such as misalignment of the lock cylinder when the lock body passes through the cover, skewed lock body, and even difficulty in assembly.

If the assembly is forced, there will be assembly quality problems such as the displacement of the cover part, which will cause the gap between the cover part and other components such as taillights to become larger or the gap will be uneven, which will seriously affect the appearance quality of the vehicle and the performance of the seat cushion lock.
