[0024] Embodiment 1

[0025] A cradle-type footrest bracket structure of a motorcycle described in this Embodiment 1, as Figure 1 and Figure 2 shown, includes a footrest bracket 3 that is mutually installed and connected with the frame 1 and the engine 2; the footrest bracket is composed of two symmetrical and irregular bend pipes 4 and a support crossbar 5 that is horizontally connected and installed between the two bend pipes and is used to strengthen the support connection of the two bend pipes and support the bottom of the engine. The engine and the footrest bracket are both connected and installed on the frame. The engine is mainly fixedly installed by relying on the frame, and the footrest bracket is installed below the engine. The two irregular bend pipes of the footrest bracket are located within the vertical downward projection area on both sides below the engine, that is, inside the lower part of the engine, and the support crossbar connects the two bend pipes to form a connected structure, and the support crossbar also supports and holds the bottom of the engine, playing a certain role in supporting the engine. Such a footrest bracket structure forms a bracket structure similar to a cradle, which not only makes the entire footrest bracket connected into a whole structure to achieve a more stable and steady purpose, but also can strengthen the support capacity for the bottom of the engine, prevent problems such as loosening when the engine is simply fixed on the frame, and still has a certain effect of supporting the engine when an accident occurs, as much as possible to protect the fixed stability of the engine, and at the same time prevent the situation of direct scraping of the bottom of the engine.

[0026] In this Embodiment 1, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the front end of the bent pipe is set to tilt forward, and a frame connecting plate 6 is provided at the end of the front end of the bent pipe. An adjustment mounting hole 7 is provided on the frame connecting plate, which forms an adjustable mounting with the mounting position on the frame. On the frame, there are a frame upper mounting hole 8 and a frame lower mounting hole 9 that form a movable mounting with the adjustment mounting hole and are arranged vertically. The rear end of the bent pipe is provided with a bent pipe rotary mounting seat 10 that forms a movable rotary mounting with the frame. On the frame, there is a frame fixing seat 11 that is sleeved and mounted with the bent pipe rotary mounting seat. The bent pipe rotary mounting seat and the frame fixing seat are connected and mounted through a movable bolt 12. The bent pipe is of an irregular shape. The middle part of the bent pipe is in the shape of a flat horizontal line. The front end of the bent pipe is tilted upward and narrowed inward. The rear end of the bent pipe is also tilted upward, but the tilting height is much smaller than that of the front end of the bent pipe. The rear end of the bent pipe forms a movable mounting with the frame through the bent pipe rotary mounting seat and the frame fixing seat. Tightening the movable bolt can form the fixed mounting of the rear end of the bent pipe and the frame. Loosening the movable bolt can form the up-and-down rotation of the rear end of the bent pipe along the frame, thus realizing the rotation of the entire footrest bracket. In this way, the front end of the bent pipe is connected and fixedly mounted to any one of the corresponding frame upper mounting holes or frame lower mounting holes through the frame connecting plate and the adjustment mounting hole, realizing the adjustment of two heights of the front end of the bent pipe, and realizing the height and angle adjustment of the entire footrest bracket to suit different riders.

[0027] In Embodiment 1, the frame connecting plate and the bent pipe are of an integrally formed structure. The frame connecting plate is set to tilt forward upward. The adjustment mounting hole is an oblong hole set to tilt. The aperture of the adjustment mounting hole is larger than the apertures of the frame upper mounting hole and the frame lower mounting hole. The integrally formed manufacturing of the frame connecting plate and the bent pipe realizes a more stable structure, lower manufacturing cost, and higher strength. At the same time, the oblong hole design of the adjustment mounting hole can make the hole size of the adjustment mounting hole larger and be more adaptable to different bolt fixings.

[0028] In Embodiment 1, the frame upper mounting hole and the frame lower mounting hole are set to tilt forward. The adjustment mounting hole and the frame upper mounting hole or the frame lower mounting hole are movably mounted through an adjustment bolt 13. Since the front end of the frame is designed to tilt forward to adapt to the installation of the engine, the frame upper mounting hole and the frame lower mounting hole are correspondingly designed to tilt forward, and the frame connecting plate is also tilted forward. In this way, it is more adaptable to installation and the force is evenly distributed, and the connection structure is more stable.

[0029] In the first embodiment, a rotary mounting seat groove hole (not shown in the figure) is provided inside the elbow rotary mounting seat, and a cylindrical convex head 14 that protrudes from the vehicle frame fixing seat and is movably inserted into the rotary mounting seat groove hole is provided. When the elbow rotary mounting seat and the vehicle frame fixing seat are installed, the cylindrical convex head will be embedded in the rotary mounting seat groove hole. When the movable bolt is not tightened, the elbow rotary mounting seat can rotate relative to a fulcrum of the vehicle frame fixing seat; such a fitting installation can achieve stable movable installation connection between the elbow rotary mounting seat and the vehicle frame fixing seat, and is also relatively stable during rotation and not easily displaced.

[0030] In the first embodiment, a front crossbar slot 15 and a rear crossbar slot 16 for the support crossbar to be inserted and arranged front and rear are provided at the bottom of the engine. When the height of the front end of the elbow is adjusted up and down, the height of the support crossbar will also be adjusted and the position of the support crossbar will also change back and forth; therefore, with the front crossbar slot and the rear crossbar slot at the bottom of the engine, it can be adapted to still be inserted into the corresponding slots to support and hold the bottom of the engine when the position of the support crossbar changes, ensuring a certain supporting capacity for the engine.

[0031] In the first embodiment, a footrest 17 is installed on the outer side surface of each elbow. A brake pedal 18 is installed on the outer side surface of one elbow, and a gear shifter 19 is installed on the outer side surface of the other elbow.

[0032] In the first embodiment, the cradle-type footrest bracket structure of this motorcycle adopts a footrest bracket structure similar to a cradle; that is, like a cradle-type footrest bracket, both sides are symmetrically composed of an elbow and a support crossbar is arranged between the two elbows to form a frame structure with a bottom supporting function; the support crossbar of this footrest bracket can not only make the connection between the two elbows more firm, stable and not easily deformed, but also play a role in supporting and holding the bottom of the engine, realizing an additional firm mounting fulcrum for the engine in addition to being fixedly installed with the vehicle frame, ensuring the firmness of the engine installation, ensuring the safety of the engine and the rider, and at the same time protecting the bottom of the engine from accidental collision and scratching, extending the driving life; in addition, the front end of this footrest bracket adopts a flexible connection method of a vehicle frame connecting plate and a rotatable adjustment method at the rear end, which can realize the adjustment of the height of the front end of the footrest bracket and the adjustment of the angle of the front end of the entire footrest bracket, and can be adjusted according to different driving sections and the height of different riders, etc., enabling the rider to have a comfortable riding posture and increasing the comfort of motorcycle travel, which is very user-friendly and highly flexible.

[0033] The above is only a preferred embodiment of the present invention, and does not impose any form of restriction on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
