Lock device for seat cushion of motorcycle

Abstract

The invention discloses a lock device for a seat cushion of a motorcycle. The lock device comprises a lock body portion structure and a locking portion structure which are opposite to each other, the lock body portion structure is fixed on a covering part, and the locking portion structure is fixed on a frame. The lock device is characterized in that a straightened flexible pull rope is arranged between the lock body portion structure and the locking portion structure, and when a lock cylinder of the lock body portion structure is driven to rotate by a key, a lock rod of the locking portion structure can be pulled through the flexible pull rope. A force transmitting action mode of the lock device for the seat cushion of the motorcycle is changed during locking and unlocking, the flexible pull rope is connected between the lock body portion structure and the locking portion structure to transmit force, influence on assembly and service due to mounting errors is avoided, assembly difficulty is reduced, assembly quality is improved, assembly time is shortened, and reliability of final products is guaranteed.

Description

technical field [0001] The invention relates to a seat cushion lock structure of a curved beam motorcycle and a scooter. [0002] Background technique [0003] 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. [0004] 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 con...

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.
