Description

Technical Field

[0001] This utility model relates to a driving assistance structure for two-wheeled vehicles. Background Technology

[0002] Motorcycles are a common means of transportation in daily life and are loved by people for their convenience. However, since motorcycles are two-wheeled, when parking for a short time, the rider needs to manually support the vehicle or get off and use a side stand to support the left side of the vehicle. This is time-consuming, laborious, and inconvenient, and causes great restriction of movement. The same applies to parking. At the same time, when the vehicle is in motion, it is easy for the vehicle to become unstable or tip over, which affects driving safety. Utility Model Content

[0003] This invention addresses the aforementioned problem by providing a two-wheeled vehicle driving assistance structure that is simple in structure and easy to use.

[0004] This utility model is constructed as follows: it includes a base set at the bottom of the two-wheeled vehicle body and a telescopic support frame set below the base. The telescopic support frame has symmetrically arranged abutment blocks that can be raised and lowered synchronously on the lower part of its two inner sides. Each abutment block has an auxiliary wheel that can also be raised and lowered synchronously on its side. The auxiliary wheels are installed on the two outermost sides of the telescopic support frame.

[0005] Furthermore, the telescopic support frame is driven to unfold or retract by a lifting drive device. When the telescopic support frame unfolds, it drives the abutment block and auxiliary wheels to rise synchronously, and when it retracts, it drives the abutment block and auxiliary wheels to descend synchronously.

[0006] Furthermore, the lifting drive device is located between the base and the telescopic support frame.

[0007] Furthermore, the telescopic support frame includes two symmetrically arranged telescopic components. Each telescopic component includes a first link, a second link, a third link, a fourth link, a fifth link, and a sixth link. One end of the first link is hinged to the telescopic end of the lifting drive device, and the other end of the first link is hinged to the middle of the second link. One end of the second link is hinged to the fixed end of the lifting drive device, and the other end of the second link is hinged to the middle of the third link. One end of the third link and one end of the fourth link are both connected to the abutment block. The other end of the fourth link is hinged to the first link, and the other end of the third link is hinged to the middle of the fifth link. One end of the fifth link is hinged to one end of the sixth link, and the other end of the fifth link is connected to the auxiliary wheel. The other end of the sixth link is hinged to the second link.

[0008] Furthermore, the lifting drive device is one of a hydraulic cylinder, a pneumatic cylinder, or an oil cylinder.

[0009] Furthermore, a shock absorber is provided between the auxiliary wheel and the telescopic support frame.

[0010] Furthermore, the abutment block is made of metal or rubber.

[0011] Furthermore, the auxiliary wheel is rotatably coupled with the telescopic support frame.

[0012] Furthermore, a speed sensor is provided on the base.

[0013] Furthermore, a controller is provided on the base.

[0014] Compared with the prior art, this utility model has the following advantages: The device has a simple structure, reasonable design, and is easy to use. When the vehicle is in motion, the lifting drive device retracts upwards, causing the telescopic support frame to unfold, raising the two abutment blocks off the ground. Simultaneously, the two auxiliary wheels do not contact the ground. At this time, only the front and rear wheels of the two-wheeled vehicle are in contact with the ground for travel. If the user tilts the vehicle (e.g., when cornering at high speed or when the vehicle tilts due to loss of control), the auxiliary wheels of the two-wheeled vehicle's auxiliary structure can provide assistance. The auxiliary wheels can extend to a corresponding degree according to the vehicle speed, thus adjusting their height accordingly to provide the appropriate assistance. In the temporary parking state, the lifting drive device extends downwards, causing the telescopic support frame to unfold. When the support frame closes, the abutment blocks descend and come into contact with the ground. At this point, the front and rear wheels of the two-wheeled vehicle, as well as the abutment blocks, are all in contact with the ground. The user does not need to hold the vehicle, and even if both feet are off the ground, the vehicle can maintain its balance and will not tip over, thus providing parking assistance. In the parking state, the lifting drive device continues to extend downward, causing the telescopic support frame to close further. This allows the two abutment blocks to lift the two-wheeled vehicle further, completing the parking process and providing stable parking assistance. There is no need to use the traditional parking frame that requires both hands to grip the motorcycle and feet to step on it. In the parking state, the two-wheeled vehicle uses the rear wheels and the two support blocks to contact the ground. Attached Figure Description

[0017] Figure 3 This is a schematic diagram of the working state of an embodiment of the present utility model. Figure 2 . Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: As Figure 1-3 As shown, a two-wheeled vehicle driving assistance structure is provided, including a base 2 disposed at the bottom of the two-wheeled vehicle body 1 and a telescopic support frame 3 disposed below the base. The telescopic support frame has symmetrically arranged abutment blocks 4 that can be raised and lowered synchronously on the lower inner sides of the two sides. Each abutment block is provided with an auxiliary wheel 5 that can also be raised and lowered synchronously on the side. The auxiliary wheels are installed on the two outermost sides of the telescopic support frame. The two abutment blocks and the two auxiliary wheels mentioned above can be disposed on both sides of the wheels of the two-wheeled vehicle body, for example, on both sides of the rear wheel 101.

[0020] When in operation: When the vehicle is in motion, the lifting drive device retracts upward, causing the telescopic support frame to unfold, raising the two abutment blocks off the ground. At the same time, the two auxiliary wheels are not in contact with the ground. At this time, only the front and rear wheels of the two-wheeled vehicle are in contact with the ground for travel. If the user tilts the vehicle (for example, when cornering at high speed or when the vehicle falls over due to loss of control), the auxiliary wheels of the two-wheeled vehicle auxiliary structure can play an auxiliary role. The auxiliary wheels can extend to a corresponding degree according to the vehicle speed. Therefore, the height position of the auxiliary wheels can be adjusted according to the vehicle speed to play a corresponding auxiliary role.

[0021] In the temporary parking state, the lifting drive device extends downward, driving the telescopic support frame to close, so that the abutment block descends and can just make contact with the ground. At this time, the front wheel, rear wheel and abutment block of the two-wheeled vehicle are all in contact with the ground. The user does not need to hold the two-wheeled vehicle. Even if the user's feet are off the ground, the two-wheeled vehicle can maintain its balance and will not tip over, thus playing a parking assistance role.

[0022] In the parking position, the lifting drive device continues to extend downwards, causing the telescopic support frame to close further, so that the two abutment blocks continue to lift the two-wheeled vehicle body to complete the parking, thereby playing a stable auxiliary parking effect, eliminating the need for the traditional parking frame that requires both hands to hold the motorcycle and feet to step on it; in the parking position, the two-wheeled vehicle body contacts the ground with the rear wheel and the two support blocks.

[0023] In this embodiment of the utility model, the telescopic support frame 3 is driven to unfold or retract by the lifting drive device 8. When the telescopic support frame unfolds, it drives the abutment block and auxiliary wheel to rise synchronously, and when it retracts, it drives the abutment block and auxiliary wheel to descend synchronously.

[0024] In this embodiment of the utility model, the lifting drive device is disposed between the base and the telescopic support frame, and the fixed end of the lifting drive device is installed on the base.

[0025] In this embodiment of the utility model, the telescopic support frame 3 includes two symmetrically arranged telescopic components 31. Each telescopic component includes a first connecting rod 311, a second connecting rod 312, a third connecting rod 313, a fourth connecting rod 314, a fifth connecting rod 315, and a sixth connecting rod 316. One end of the first connecting rod is hinged to the telescopic end of the lifting drive device, and the other end of the first connecting rod is hinged to the middle of the second connecting rod. One end of the second connecting rod is hinged to the fixed end of the lifting drive device, and the other end of the second connecting rod is hinged to the middle of the third connecting rod. One end of the third connecting rod and one end of the fourth connecting rod are both connected to the abutment block. The other end of the fourth connecting rod is hinged to the first connecting rod, and the other end of the third connecting rod is hinged to the middle of the fifth connecting rod. One end of the fifth connecting rod is hinged to one end of the sixth connecting rod, and the other end of the fifth connecting rod is connected to the auxiliary wheel. The other end of the sixth connecting rod is hinged to the second connecting rod.

[0026] The telescopic end of the aforementioned lifting drive device may be provided with a hinge seat A, which is hinged to one end of the first connecting rod; the outer wall of the fixed end of the lifting drive device may be provided with a hinge seat B, which is hinged to one end of the second connecting rod.

[0027] In this embodiment of the utility model, the lifting drive device is one of an oil cylinder, a hydraulic cylinder, or a pneumatic cylinder, or it can also be an electric drive device in the prior art, as long as it can achieve stable lifting.

[0028] In this embodiment of the invention, a shock absorber is provided between the auxiliary wheel and the telescopic support frame to improve stability and comfort.

[0029] In this embodiment of the invention, the abutment block is made of metal or rubber.

[0030] In this embodiment of the invention, the auxiliary wheel is rotatably coupled with the telescopic support frame.

[0031] In this embodiment of the invention, the parking height is lower than the parking height, the tilt assist height is higher than the parking height, and the assist wheels extend outward.

[0032] Example 2: Based on Example 1, in this embodiment of the present invention, a speed sensor 6 is provided on the base; the speed sensor is used to sense the speed of the vehicle body.

[0033] A controller 7 is provided on the base, which is electrically connected to the speed sensor and the lifting drive device.

[0034] The aforementioned controller can provide a first control command based on the vehicle's speed and a second control command based on parking requirements. The faster the speed of the two-wheeled vehicle detected by the speed sensor, the greater the outward extension of the telescopic support frame driven by the lifting drive device. In other words, although only the front and rear wheels of the two-wheeled vehicle are in contact with the ground, when the user tilts the vehicle (e.g., when attempting to corner at high speed or when the vehicle tilts due to loss of control), the auxiliary wheels of the two-wheeled vehicle's auxiliary structure can provide assistance. Since the auxiliary wheels can extend to a corresponding degree according to the vehicle speed, the auxiliary wheels in this design can adjust their position accordingly to provide the corresponding assistance. For example, the speed range of the aforementioned vehicle can be either stepped or continuous. Taking the staged type as an example, the vehicle speed range can be any value such as 0~10, 10~30, 30~50, 50~70, 70~125 (km / hr). The speed of different stages can correspond to the lifting drive device driving the telescopic support frame to move and change the height of the auxiliary wheels. Taking the continuous type as an example, the vehicle speed range is greater than 0, such as any value from 0 to 125 km / hr.
