Description

The present invention relates to a landing gear transmission structure, and more particularly, to a transmission structure that assists in pushing up a motorcycle landing gear so that a user can easily park a motorcycle in a limited space.

In cities, parking spaces for parking bikes are small and the number is extremely limited, and there are often various types of bikes already where you want to park your bike. And even if you think you finally found an empty parking space, there may be only enough space for one bike to fit in. If the driver was wearing a mini skirt or high heels, It is extremely difficult to stop by packing. So if you definitely want to park your bike, you have to go to that place sooner than others.

The situations described above are frequent and difficult to avoid. A difficult cause to stop the bike is how to pull out the bike landing gear after stopping. This pulling out operation needs to be performed with hands and feet, and is difficult to perform in a narrow and small space. If you can't do it while standing on the side of the bike, you can only do it by standing diagonally backwards, and if you accidentally do it, the bikes on the left and right can also be killed by Domino. It can't be done, and it causes trouble for people.

As a result of searching for the most economical solution in view of the above-described problems when stopping the motorcycle, the present invention has the A-type stand that the motorcycle originally has, and a protrusion on one side and a fixed base plate. By using a coil-type return spring connected between the two, during operation, the A-type stand is attached to the bottom panel exactly, and when supporting the bike by hand, the user only applies a little force, The A-type stand can be set in a standing state, and the already extended coil-type return spring can be automatically returned to the original state so that the stand is accommodated.

The present invention utilizes an A-type stand that is originally provided on a motorcycle. The Y-type push rod is installed by attaching the guide groove that can hold the electric motor of the present invention and the Y-type push rod to the fixing device around the bottom of the motorcycle. Can be automatically pivoted and adjusted along the gear wheel to maintain the most appropriate contact angle with the A-type stand.

An object of the present invention is to provide a landing gear transmission structure for assisting the push-up of a motorcycle landing gear so that a user can easily park a motorcycle in a limited space.

The landing gear transmission structure according to the present invention is mainly composed of a gear wheel, an electric motor, and a Y-type push rod. Among them, one side of the gear wheel is provided with an electric motor, and is connected to a transmission shaft of the electric motor, and an obliquely upper portion thereof meshes with a Y-type push rod.

The landing gear transmission structure according to the present invention is mainly composed of a gear wheel, an electric motor, and a Y-type push rod. Among them, the electric motor is fixed below the bottom of the motorcycle, but a space for moving the gear wheel and the Y-type push rod is secured.

The landing gear transmission structure according to the present invention is mainly composed of a gear wheel, an electric motor, and a Y-type push rod. Among them, the lower edge portion of the Y-type push rod has a plurality of feed holes and meshes with the gear wheel through at least one feed hole, and the upper edge portion pivots to induce the expansion / contraction direction. For this reason, it is sandwiched between the U-shaped guide grooves provided on the bottom of the motorcycle.

It is explanatory drawing which showed the mechanism of the landing gear transmission structure of this invention.

Please refer to FIG. FIG. 1 is an explanatory view showing the mechanism of the landing gear transmission structure of the present invention. The landing gear transmission structure 10 according to the present invention is mainly composed of a combination of a gear wheel 11, an electric motor 12, and a Y-type push rod 13. Among them, one side of the gear wheel 11 is provided with an electric motor 12 and is connected to a transmission shaft 14 of the electric motor 12, and an obliquely upper part thereof is engaged with a Y-type push rod 13. The electric motor 12 is fixed below the bottom of the motorcycle, but a space for moving the gear wheel 11 and the Y-type push rod 13 is secured. The lower edge portion 15 of the Y-type push rod 13 includes a plurality of feed holes, and at least one feed hole and the gear wheel 11 are engaged with each other. Further, the upper edge portion 16 is sandwiched by a U-shaped guide groove that is pivotally provided on the bottom of the motorcycle in order to pivot and guide its expansion / contraction direction. In the landing gear transmission structure 10 of the present invention, the gear wheel 11 is interlocked by the electric motor 12, and when the gear wheel 11 rotates counterclockwise, the Y-type push rod 13 engaged with the gear wheel 11 is pushed downward. The A-type stand 17 in contact therewith rotates a coil-type spring (not shown) downward and extends until it no longer extends. Then, by lifting the motorcycle (not shown), one tire is suspended in the air, and the other tire is left on the ground, thereby completing the operation of stopping the motorcycle.

Still referring to FIG. The present invention is used in conjunction with a motorcycle landing gear structure. A coil-type return spring (not shown) is connected between a protrusion 18 usually provided on one side of the A-type stand 17 included in the motorcycle landing gear structure and a fixed base plate. As a result, the A-type stand 17 can be maintained in a state where it is tightly attached to the bottom plate during operation. In addition, if the user applies a little force while supporting the bike with his hand, the standing A-type stand 17 will automatically return to its original position and the stand will be retracted. The wheel can be put on the ground at the same time to be ready for driving.

As shown in FIG. 1, the present invention utilizes an A-type stand 17 that is originally provided on a motorcycle. Attach the present invention to a position where it can be easily interlocked, and pivotally set a U-shaped guide groove (not shown in this figure) that can sandwich the electric motor 12 and the Y-type push rod 13 in the peripheral fixing device of the motorcycle bottom. Thus, the Y-type push rod 13 is automatically pivoted along the gear wheel 11 and adjusted so as to have the best contact angle with respect to the A-type stand 17. With the above structure, when actually operating, if the electric switch provided on the vehicle body is pressed after turning off the engine, the electric motor is activated instantly and the gear wheel 11 rotates counterclockwise. The Y-type push rod 13 engaged and interlocked advances forward, and the front end of the Y-type push rod 13 comes into contact with the horizontal bar 19 of the A-type stand 17 so that the A-type stand 17 can stand. At the same time, the user can easily and stably park the motorcycle on the spot simply by pulling the tail end of the vehicle body slightly backward. If you want to walk while pushing the bike, simply push the tail end of the car lightly forward and the coil-type return spring will repel the A-type stand 17 and the Y-type push rod 13 The wheel 11 is interlocked and the stand is stored, so that both wheels of the motorcycle can touch the ground and smoothly push the motorcycle as it is.

The power of the battery of the motorcycle used in the landing gear transmission structure 10 of the present invention is used only at the moment of pushing and moving. The switch is concealed in a position that can be reached by the tail end of the car body, connected to the motorcycle battery, electric motor and electrical switch with a power cord, and is a safe switch design that only starts after the motorcycle engine is turned off. ing.

The electric motor 12 of the present invention has no control force when power is not passed, and interlocks with an original coil-type return spring. For this reason, the power of the battery can be saved and the mechanism of the device can be simplified.

The front end recessed groove of the Y-type push rod 13 of the present invention is in contact with the horizontal bar 19 of the A-type stand 17, and the Y-type push rod 13 includes It is sandwiched between the lower gear wheel 11 and the gear wheel 11 is connected to the transmission shaft 14 of the electric motor 12, and the electric motor 12 is fixed below the bottom of the motorcycle. A space for operating the gear wheel 11 is secured.
