Description

The installation structure of motorcycle frame and seat cushion lock, rear armrest and tail light shield

technical field

The invention relates to a mounting structure between parts of motorcycles, and belongs to the technical field of mechanical structures.

Background technique

On the existing motorcycle, the seat cushion lock and the tail light shield are respectively provided with separate mounting brackets, i.e. a multifunctional mounting bracket and a tail light shield mounting bracket, both of which are installed on the vehicle frame respectively. Such a structural arrangement not only increases the number of parts, assembly complexity and manufacturing cost, but also affects the compactness of the vehicle and reduces the strength of the vehicle frame. For motorcycles with a sporty style, the body is required to be more compact than ordinary motorcycles, so the requirements for the frame are higher.

Contents of the invention

The present invention improves on the above-mentioned technical problems, and intends to provide a motorcycle frame, a seat cushion lock, a rear armrest, and a taillight shield installation structure, which reduces a taillight shield installation bracket, saves manufacturing costs, and improves assembly efficiency. The strength and compactness of the whole vehicle are especially suitable for motorcycles with sporty styling.

For this reason, the technical solution adopted by the present invention is: a motorcycle frame, a seat cushion lock, a rear armrest, and a tail light shield installation structure, and a multifunctional mounting bracket (E) is welded on the frame (A). ), the multifunctional mounting bracket (E) is a stamped sheet metal part, and a strip hole (1) is provided at the center of the sheet metal part for the bolt of the seat cushion lock (B) to pass through. There are two rear armrest mounting holes (2) arranged at intervals up and down on the left side and the right side of the part respectively for installation with the rear armrest (C), and two left and right symmetrically arranged The mounting holes (3) of the tail light guards are used to install with the tail light guards (D). The plane of the sheet metal part where each tail light guard The left side of the strip hole (1) is punched with an upwardly protruding seat lock installation cavity (4). The seat cushion lock (B) is placed in the seat cushion lock installation cavity (4). (4) There are two seat cushion lock installation holes (5) and a lock seat adjustment hole (6). The two seat cushion lock installation holes (5) are set at intervals up and down, and are used to install the seat cushion lock (B). , the lock seat adjustment hole (6) is located in the middle position on the left side of the two seat cushion lock installation holes (5).

In the above solution, a downward flanging (7) is provided along the periphery of the sheet metal part, and reinforcing ribs (8) extending forward and backward or/and left and right are punched in the sheet metal part. The strength of the multifunctional mounting bracket is improved by adding flanges and ribs.

Further, a first weight-reducing notch (9) is set at the middle position of the front part of the sheet metal part, a second weight-reducing notch (10) is set at the center position of the rear part of the sheet metal part, and the second weight-reducing notch (10) (10) is provided with a gap for the tail light line (11) at the junction of the right edge and the front edge, and two right-angled trapezoidal weight-reducing holes (12) arranged symmetrically from left to right are also provided on the sheet metal part. On the premise of ensuring the strength of the multi-functional mounting bracket, the weight of the mounting bracket is reduced by adding weight-reducing notches and holes, and the tail light wires give way to the gaps for the tail light wires to pass through.

The multi-functional mounting bracket is welded on the frame, the seat cushion lock is located in the seat cushion lock installation cavity, and is installed through two seat cushion lock installation holes, the tongue of the seat cushion lock protrudes from the strip hole, when the seat cushion lock In the event of stagnation, a tool can be used to insert it from the adjustment hole of the lock base to move it. The rear armrest is installed and fixed through four rear armrest mounting holes, and the tail light shield is fixed and fixed through two tail light shield mounting holes, thus realizing the installation of the vehicle frame, multi-functional mounting bracket, seat cushion lock, rear armrest and tail light shield.

The beneficial effects of the present invention are:

(1) The multi-functional mounting bracket integrates the installation of the rear armrest, the seat cushion lock, and the tail light cover, saving a tail light cover installation bracket, which is different from the structure of the existing motorcycle with a separate tail light cover installation bracket. It saves money for the development of the whole vehicle and makes the whole vehicle more compact, especially suitable for sports-style motorcycles;

(2) The multi-functional mounting bracket is stamped and formed by sheet metal parts. The processing technology is simple, the strength is good, and the material is saved, which ensures the accuracy of parts manufacturing and facilitates the assembly of the whole vehicle. It directly avoids rear armrests, taillight shields, and seat cushion locks. The problem of poor fit between each other improves the loading efficiency of workers.
