Locomotive center column support structure

Abstract

This invention relates to a motorcycle center column support structure, which is mainly installed at the bottom of the motorcycle body. It includes a main frame, a center column unit pivotally connected to the main frame, and a locking structure. The length of the center column unit is shorter than the length from the bottom of the motorcycle body to the ground. This allows the rider to easily lower the center column unit and raise the center column. Through the center column unit being shorter than the ground, it can be slightly tilted to one side to support the vehicle in conjunction with the front and rear wheels, achieving the effect of supporting the entire length of the motorcycle body and the function and advantages of a labor-saving upright column.

Description

Locomotive center column support structure Technical Field

[0001] This creation relates to the field of vehicle parking, and specifically refers to a structural technology that supports the vehicle body to remain stationary when the vehicle is parked. Prior Technology

[0002] Note that when parking a motorcycle, it is generally supported by a parking stand, such as a center stand or side stand, to prevent it from tipping over. For example, side stands are used for temporary support when parking temporarily, while center stands are more commonly used for longer periods, providing better support and stability. However, while using a center stand to prop up the motorcycle is more stable and takes up less space when parking, it requires considerable strength, which can be inconvenient for women or the elderly who may have less strength.

[0003] Therefore, an extension is found in Chinese Patent No. M677593, which describes an improvement to the structure of a locomotive center column and a U-shaped tube body. This involves a U-shaped tube body with positioning plates on the upper sides of both sides, with a fixing block between them. One positioning plate has a spring hook rod, and each of the two foot posts has a foot seat. One side foot post has a side step rod, which is reinforced by connecting ribs. A pedal is provided at the rear end. The two foot posts of the U-shaped tube body extend downwards, and the side step rods and connecting ribs are also installed downwards. A reinforcing connecting rod is provided in the middle of the two extended foot posts.

[0004] The aforementioned structure extends downwards through the two side pillars to support the tires, facilitating the lifting of the vehicle to a stationary position. In other words, the longer the center pillar, the greater the lever arm from the fulcrum to the point of application of force, making it easier to lift a heavy vehicle body using the lever principle. However, the lifted vehicle can only be supported by the two side pillars of the center pillar and either the front or rear wheel, with the support range limited to the front or rear half. This can lead to instability in the center of gravity. If the ground where the vehicle is parked is uneven, the support points of the side pillars are even more unstable, causing the vehicle to tilt, sway, or tip over.

[0005] Therefore, the creator, taking into account this, and drawing upon years of extensive design, development, and practical manufacturing experience in the relevant industry, researched and improved upon the shortcomings of the previous structure to provide a motorcycle center column support structure, aiming to achieve better practical value. Summary of the Invention

[0006] The main purpose of this invention is to provide a locomotive center column support structure, especially a locomotive center column support structure that provides stable support and effortless operation.

[0007] The main purpose and function of the locomotive center column support structure in this creation are achieved through the following specific technical means:

[0008] It is mainly installed at the bottom of the vehicle body and includes a main frame, a center column unit pivotally connected to the main frame, and a locking structure. The length of the center column unit is shorter than the length from the bottom of the vehicle body to the ground. This allows the rider to easily lower the center column unit and raise the center column. Through the center column unit which is shorter than the ground, it can be slightly tilted to one side to support the vehicle in conjunction with the front and rear wheels, achieving the support effect of the entire length of the vehicle body and the function and advantages of a labor-saving upright.

[0009] In a preferred embodiment of the motorcycle center column support structure of this invention, the center column unit further includes two corresponding legs and a support rod located between the two legs, so that one of the legs of the center column unit cooperates with the front and rear wheels to support the vehicle when it is stationary.

[0010] In a preferred embodiment of the locomotive center column support structure of this invention, the locking structure is further installed between the main frame and the center column unit to lock the center column unit after it is lowered. Simple Explanation of the Diagram

[0012] To provide a more complete and clear disclosure of the technical content, creative purpose, and effects achieved in this work, a detailed explanation is provided below. Please also refer to the accompanying drawings and figure numbers:

[0013] First, please refer to the first and second figures showing the exploded and assembled appearance diagrams of the motorcycle's center pillar support structure. The main component is the center pillar support structure installed at the bottom of the motorcycle body. This center pillar support structure (A) includes…

[0014] A main frame (1) is installed at the bottom of the vehicle body (B);

[0015] A central column unit (2) is provided with two corresponding legs (21) and a support rod (22) located between the two legs (21). The ends of the two legs (21) are pivotally connected to the main frame (1). The central column unit (2) can be in a vertically retracted state relative to the main frame (1) or in a parallel lowered state relative to the main frame (1) [as shown in Figures 3-4].

[0016] A locking structure (3) is installed between the main frame (1) and the middle column unit (2) to lock the middle column unit (2) after it is lowered; characterized in that:

[0017] The length of the center pillar unit (2) in the lowered state is shorter than the length from the bottom of the vehicle body (B) to the ground.

[0018] In actual use, the size of the wheels is related to the distance between the bottom of the vehicle body (B) and the ground. The height of the vehicle body (B) is set before the vehicle leaves the factory. Therefore, the length of the middle pillar unit (2) of the middle pillar support structure (A) in this invention is also set to be shorter than the distance between the bottom of the vehicle body (B) and the ground. Please refer to Figures 1 to 7. When the vehicle is in motion, the middle pillar support structure (A) is in a retracted state, that is, the middle pillar unit (2) is retracted vertically relative to the main frame (1). When parking, the rider only needs to push the middle pillar unit (2) with his foot to make the middle pillar unit (2) parallel to the main frame (1) and lower it. At this time, the rider can tilt the vehicle slightly to the left or right by the ground height and his own habits. The middle pillar unit (2), which is shorter than the ground, supports the vehicle by tilting slightly to one side in conjunction with the front and rear wheels, achieving the three-point support effect of the entire length of the vehicle body (B) and the function and advantages of the labor-saving pillar.

[0019] In addition, the locking structure (3) can lock the middle column unit (2) when it is lowered in parallel with the main frame (1); furthermore, the locking structure (3) is an elastic element (31), with one end of the elastic element (31) positioned on the main frame (1) and the other end positioned on the middle column unit (2).

[0020] The foregoing embodiments or drawings are not intended to limit the structural form of this invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this invention.

[0021] Advantages of this work:

[0022] 1. The rider can easily lower the center post unit by gently kicking it with their foot, making it parallel to the main frame, thus achieving the effect of a center post upright. This method is labor-saving and easy for anyone to operate.

[0023] 2. The rider uses the center pillar unit, which is shorter than the length from the bottom of the vehicle to the ground, to support the vehicle by slightly tilting the front and rear wheels to the left or right, achieving a three-point support effect along the entire length of the vehicle. It also has a small tilt angle when parked and does not take up much space.

[0024] In conclusion, the embodiments of this invention can indeed achieve the expected effects of use, and the specific structure disclosed therein has not only never been seen in similar products, but has also not been disclosed before the application. It fully complies with the provisions and requirements of the Patent Law. Therefore, I hereby file an application for a utility model patent and respectfully request your review and grant of a patent, which would be of great benefit to you.
