Description

Technical Field

[0001] The present application relates to the field of heavy motorcycles, and more specifically, to a heavy motorcycle structure for switching between a reverse three-wheel and a two-wheel configuration. Background Art

[0002] At present, the three-wheeled motorcycles in the heavy motorcycle field are not good at passing. The width of the three-wheeled motorcycle body is disadvantageous in urban commuting road scenes. In terms of maneuverability, the front of the three-wheeled motorcycle is inevitably a bit bulky, difficult to control, and requires a lot of strength, sacrificing maneuverability in order to gain stability. In terms of stability, safety, and grip, two-wheeled motorcycles are difficult to achieve and dangerous in cornering.

[0003] The heavy-duty three-wheeled motorcycles currently on the market, whether they are the front-wheel locked three-wheeled motorcycles (cannot tilt together) from brands such as Bombardier, or the horizontal multi-link front suspension LMW (Leaning Multi-Wheel) three-wheeled motorcycles launched by Yamaha (can tilt together), are unable to achieve a structure that switches from a three-wheeled motorcycle to a two-wheeled motorcycle, and their passability and maneuverability are both disadvantageous.

[0010] The control mechanism drives the first connecting component and the second connecting component to rotate and to close or separate from each other;

[0011] The present application enables the two front wheels to move closer to each other and become one front wheel through the action of the first connecting component and the second connecting component, thereby turning the motorcycle in a three-wheel state into a common two-wheel motorcycle, realizing a motion structure that switches between two-wheel and three-wheel forms, and further allowing the user to make a choice between maneuverability and stability.

[0012] Furthermore, the control mechanism includes a button, a rotating shaft fixed on the frame, and an air pump pull rod rotatably arranged on the rotating shaft; the button is used to drive the air pump pull rod to extend and retract.

[0013] Furthermore, the first connecting assembly includes a fixed rod fixed on the piston rod of the air pump pull rod, a connecting plate fixed on the fixed rod, a rocker arm rotatably arranged on the connecting plate, and a support rod rotatably arranged on the rocker arm, and one end of the support rod is rotatably connected to the frame.

[0014] Furthermore, the first connecting assembly includes a guard plate rotatably connected to the fixing rod, and one end of the guard plate is rotatably connected to the vehicle frame.

[0015] Furthermore, the first connecting assembly also includes a spring shock absorber arranged between the connecting plate and the rocker arm.

[0029] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0030] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Reference Figure 1-4, a heavy motorcycle structure for switching between reverse three-wheel and two-wheel forms, comprising a frame 1, a first connecting component 2, a second connecting component 3, and a control mechanism (not shown in the drawings); the first connecting component 2 and the second connecting component 3 are symmetrically arranged on the rear ends of the frame 1, respectively, and the first front wheel 12 and the second front wheel 13 on the motorcycle are respectively installed on the first connecting component 2 and the second connecting component 3. The control mechanism is installed at the front end of the motorcycle, and is used to drive the first connecting component 2 and the second connecting component 3 to operate. Through the action of the first connecting component 2 and the second connecting component 3, the two front wheels can be brought close to each other to become one front wheel, so that the motorcycle in the three-wheel state becomes the same as an ordinary two-wheel motorcycle, realizing the motion structure of switching between two-wheel and three-wheel forms, and then freely choosing between maneuverability and stability. In the three-wheel state (the front two wheels are separated), the wheel center distance is a570mm, the maximum width b of the body is 954mm, and the body width of less than 1M provides stability while also having good passability. In the two-wheel state (the front two wheels are combined), the maximum width c of the vehicle body is 830mm (handlebars) and the steering angle is 34°, which is no different from an ordinary two-wheeled motorcycle.

[0033] The structure of the first connecting component 2 is the same as that of the second connecting component 3 .

[0034] The control mechanism includes a button, a rotating shaft 4, and an air pump rod 5; the rotating shaft 4 is fixed on the frame 1, and the air pump rod 5 is rotatably arranged on the frame 1 through the rotating shaft 4. The button is used to drive the air pump rod 5 to rotate and retract.

[0035] The first connecting assembly 2 includes a fixed rod 6, a guard plate 7, a support rod 8, a connecting plate 9, a rocker arm 10, and a spring shock absorber 11; the fixed rod 6 is fixedly arranged on the piston rod of the air pump pull rod 5, one end of the guard plate 7 is rotatably arranged on the frame 1, and the other end is rotatably arranged on the piston rod of the air pump pull rod 5 through the fixed rod 6, the connecting plate 9 is fixedly arranged on the fixed rod 6, one end of the support rod 8 is rotatably connected to the frame 1, and the other end is rotatably arranged on the rocker arm 10, the rocker arm 10 is rotatably arranged on the connecting plate 9, one end of the spring shock absorber 11 is connected to the connecting plate 9, and the other end is connected to the rocker arm 10, and the first front wheel 12 and the second front wheel 13 of the motorcycle are respectively installed on the rocker arm 10. Under the action of the guard plate 7, it is directly pushed and pulled by the air pump pull rod 5, and then swings left and right, thereby realizing the switching function. Under the action of the support rod 8, a swinging structure of "parallelogram d" is formed with the guard plate 7, providing a more stable dynamic structure. At the same time, the overall connection strength is strengthened to support the rocker arm 10; through the action of the spring shock absorber 11, the shock absorption function of the front wheel is realized.

[0036] The specific operation method of switching a motorcycle from a three-wheel state to a two-wheel state is as follows:

[0037] The control mechanism drives the first connecting assembly 2 and the second connecting assembly 3, so that the two air pump pull rods 5 are rotated close to each other and the piston rod is shortened, and the guard plate 7, the support rod 8 and the connecting plate 9 are moved together, so that the two rocker arms 10 are close to each other until the two front wheels are close to each other to form one front wheel. In this way, the two-wheel state and the three-wheel state can be switched at will, and the trade-off between maneuverability and stability can be made at will.

[0038] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
