Description

Motorcycles with shock absorption function

This invention relates to a motorcycle, and more particularly to a motorcycle with shock absorption functionality.

In conventional technology, rear shock absorbers are typically located on either side of the storage box. If a motorcycle is to use a centrally mounted rear shock absorber, it's often impossible to install a storage box under the seat because the central shock absorber might interfere with the storage box. This causes inconvenience for the user, making it difficult to find suitable space to store helmets or other large items.

This invention provides a motorcycle with shock absorption function to solve problems in the prior art, comprising a frame, a power unit, a shock absorber, a storage box, and a seat. The frame includes a crossbar. The power unit is mounted on the frame, and includes an engine cylinder and an output shaft. One end of the shock absorber is rotatably connected to the crossbar, wherein, in a top-view projection, the shock absorber is located within the width of the engine cylinder. The storage box is connected to and supported by the crossbar. The seat is adapted to cover the storage box.

In one embodiment, the storage box includes a first fixing part that fixes the crossbar.

In one embodiment, the motorcycle further includes a rocker arm unit, wherein the rocker arm unit is hinged to the power unit, the rocker arm unit is adapted to pivot about an axis, the output shaft is located on the axis, the rocker arm unit includes a first rocker arm and a second rocker arm, and the shock absorber passes between the first rocker arm and the second rocker arm.

In one embodiment, the motorcycle further includes a linkage unit, wherein the other end of the shock absorber is connected to the linkage unit, which is connected to the power unit and the rocker arm unit.

In one embodiment, the frame further includes a head tube, a left extension tube, a right extension tube, a left hanger tube, and a right hanger tube. The left extension tube is directly or indirectly connected to the head tube, the right extension tube is directly or indirectly connected to the head tube, the left hanger tube is connected to the underside of the left extension tube, the right hanger tube is connected to the underside of the right extension tube, one end of the crossbar is connected to the left hanger tube, and the other end of the crossbar is connected to the right hanger tube.

In one embodiment, the frame further includes a crossover connector, one end of which is connected to the upper side of the left extension tube, and the other end of which is connected to the upper side of the right extension tube. The storage compartment includes a second fastener that fastens the crossover connector.

In one embodiment, the motorcycle further includes a rear wheel, which is rotatably connected to the rocker arm unit, wherein the crossbar is positioned below the upper edge of the rear wheel in a vertical direction.

In one embodiment, the storage box includes a box body and a flange formed at the upper edge of the box body, a first fixing portion formed at the bottom of the box body, and a second fixing portion formed at the flange.

In one embodiment, the locomotive further includes a first fastener that passes through the first fixing portion from the inside of the housing to lock the first fixing portion to the crossbar.

In one embodiment, the locomotive further includes a second fastener that passes through the second fixing portion from the upper side of the flange to lock the second fixing portion to the cross-connector.

In this embodiment of the invention, one end of the shock absorber is rotatably connected to a crossbar, and the storage box is connected to and supported by the crossbar. Because the shock absorber is positioned low, the space above it can be used to install the storage box (i.e., the storage box under the seat). In one embodiment, the storage box of this invention can accommodate a helmet or other large items.
