Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to an off-road motorcycle. Background Art

[0002] Nowadays, more and more people like to ride motorcycles. As a main category of motorcycles, off-road motorcycles also have a wide range of audiences. When driving a motorcycle, the riding posture is an aspect that many motorcycle drivers tend to overlook. However, a correct riding posture can not only effectively improve the comfort during riding but also better enhance the driver's control ability of the motorcycle.

[0003] The following deficiencies still exist in the prior art:

[0004] Currently, the pedals of off-road motorcycles are generally set slightly closer to the front of the motorcycle than the driver's sitting position. In this way, when the driver is driving an off-road motorcycle, the position where the driver's feet step on the pedals is also closer to the front of the motorcycle compared to the driver's hips. In this structure, when the driver wants to adjust the sitting posture during driving, since the driver's feet are important force application points and the body center of gravity is biased towards the rear of the feet, the driver's body needs to have a forward inclination trend before the driver's body can be lifted off the seat cushion. And since the body load is applied to the handlebars of the motorcycle after the driver's body is lifted, if the driver wants to turn the handlebars of the motorcycle at this time, the driver needs to exert more force, thus affecting the controllability of the motorcycle. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an off-road motorcycle. By changing the position of the footrest on the frame, the driver is guided to change the riding posture when riding the motorcycle, enabling the driver to maintain a more standard riding posture and facilitating the improvement of the driver's control ability of the motorcycle.

[0006] The purpose of the utility model is achieved as follows:

[0007] An off-road motorcycle, including a frame, on which a footrest, a front wheel, and a rear wheel are arranged, and the footrest is fixed on the frame;

[0008] The distance between the axis of symmetry of the footrest and the axis of the front wheel is wheelbase A;

[0009] The distance between the axis of symmetry of the footrest and the axis of the rear wheel is wheelbase B;

[0010] The ratio of wheelbase A to wheelbase B is 7:3.

[0011] Preferably, the frame is detachably provided with an adjusting frame, and the adjusting frame is provided with a hinge seat;

[0012] A hinge portion is formed on the pedal, and the pedal is hinged to the hinge seat of the adjusting frame through the hinge portion.

[0013] Preferably, a connecting portion is formed on the adjusting frame, and a first connecting hole is formed in the connecting portion;

[0014] A connecting groove is recessed and formed on the vehicle frame, and a second connecting hole is formed in the connecting groove;

[0015] The connecting portion can cooperate with the connecting groove to facilitate the alignment of the first connecting hole and the second connecting hole, so that the adjusting frame can be connected to the vehicle frame through bolts.

[0016] Preferably, the edge of the connecting groove is formed as a positioning side wall;

[0017] The peripheral contour of the connecting portion matches the contour of the positioning side wall. When the connecting portion is connected to the connecting groove, the periphery of the connecting portion can abut against the positioning side wall, which is convenient for aligning the first connecting hole and the second connecting hole.

[0018] Preferably, a blocking portion is further formed in the hinge seat;

[0019] An abutting convex block is protrudingly formed at the end of the hinge portion;

[0020] When the pedal is in the retracted state, the pedal rotates upward and the upper end surface of the pedal fits against the side surface of the vehicle frame;

[0021] When the pedal is in the unfolded state, the abutting convex block abuts against the blocking portion, restricting the rotation of the hinge portion.

[0022] Preferably, the hinge seat is obliquely arranged on the adjusting frame, and the angle E between the axis of the hinge seat and the horizontal plane is 30°-40°.

[0023] A torsion portion is formed on the hinge portion;

[0024] When the pedal is connected to the hinge seat through the connecting portion and the pedal is in the unfolded state, the upper end surface of the pedal can be kept upward through the torsion portion.

[0025] Preferably, a plurality of anti-slip teeth are protrudingly formed on the periphery of the pedal.

[0026] The outstanding and beneficial technical effects of the present utility model compared with the prior art are:

[0027] 1. By placing the pedal position at the rear, when the driver needs to adjust their sitting posture during riding, since the pedal is located behind the center of gravity of the body, it is easier for the driver to lift their body off the seat. During this process, the forward inclination amplitude of the driver's body decreases, so the force exerted on the motorcycle handlebar also decreases, and the impact on the controllability of the motorcycle is smaller. At the same time, because the structure in this technical solution can make it easier for the user to lift their body off the seat, the user can also adjust their sitting posture more quickly and then sit back on the seat, further reducing the risk of motorcycle out of control.

[0028] 2. When the driver is riding a motorcycle, since the pedal position is closer to the rear of the motorcycle than the driver's buttocks, and the driver needs to step on the pedal when driving, the driver's body will naturally tilt forward due to the position of the feet, enabling the driver to drive the motorcycle in a better posture. This reduces the wind resistance during motorcycle driving. At the same time, during the acceleration process of the motorcycle, the forward-tilted body, due to the action of gravity, can also well reduce the impact of inertia on the driver's body.

[0043] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the accompanying drawings. However, the present utility model is not limited to these embodiments

[0044] As Figure 1 and Figure 2 shown, an off-road motorcycle includes a frame 1, a footrest 4, a front wheel 2 and a rear wheel 3 are arranged on the frame 1, and the footrest 4 is fixed on the frame 1

[0045] The distance between the axis of symmetry line 49 of the footrest 4 and the axis of the front wheel 2 is the wheelbase A21

[0046] The distance between the axis of symmetry line 49 of the footrest 4 and the axis of the rear wheel 3 is the wheelbase B31

[0047] It should be noted that the axis of symmetry line 49 mentioned here is the line that makes both sides of the footrest 4 symmetrical when the footrest 4 is placed horizontally

[0048] The ratio of the wheelbase A21 to the wheelbase B31 is 7:3. Thus, the position of the footrest 4 in this technical solution can be closer to one end of the rear of the vehicle

[0049] Because during the riding process, the driver will sit on the seat cushion 6, hold the grip 5 with the hand, and step on the footrest 4 with the foot. Therefore, the position of the footrest 4 can greatly affect the driver's posture when driving the motorcycle

[0050] When the position of the footrest 4 is closer to the rear of the motorcycle, and the positions of the driver's buttocks and hands remain unchanged, it will make the driver's upper body naturally tilt towards the front of the vehicle, thereby reducing the height of the driver's head and reducing the influence of the driver's body by wind resistance

[0051] At the same time, the center of gravity of the driver's body will also move forward and the position of the center of gravity will be lowered. When the motorcycle is accelerating or driving at high speed, the forward leaning body is affected by gravity, so that the body has a certain force toward the front of the motorcycle. Therefore, during the acceleration of the motorcycle, the influence of inertia on the driver's body can be reduced, or during the driving of the motorcycle, the force exerted by wind resistance on the driver can be reduced, making it easier for the driver to maintain the driving posture and more easily hold the handlebar 5 of the motorcycle, so as to ensure that the driver's control over the vehicle will not be affected.

[0052] Furthermore, when the driver of a current off-road motorcycle wants to raise his body to adjust his sitting position, he will first lean forward, and then use his legs to exert force to facilitate himself to lift his body. Since a forward movement trend will be generated during the process of the driver's body leaning forward, the center of gravity of the body will move forward, resulting in greater pressure being applied to the handle 5 of the motorcycle, making the handle 5 more difficult to rotate. At this time, since the driver only has his hands and feet to play a supporting role, when the handle 5 needs to be rotated, it is easy to cause the center of gravity of the driver and the vehicle to shift and thus cause the vehicle to lose control. The structure of the current off-road motorcycle will cause the driver to have a longer time to lift his body. If an unexpected situation occurs during this period of time, it is easy to cause the motorcycle to lose control, thereby causing accidents such as vehicle damage or driver injury.

[0053] The present technical solution places the foot pedal 4 at the rear. When the driver wants to stand up, the driver's body is already in a forward-leaning state, so the legs can directly exert force to help the driver's buttocks lift off the seat cushion 6, thereby reducing the risks encountered by the driver during driving.

[0054] like Figures 1-4 As shown, the vehicle frame 1 is detachably provided with an adjusting frame 7 , and the adjusting frame 7 is provided with a hinge seat 71 .

[0055] A hinge portion 41 is formed on the foot pedal 4 , and the foot pedal 4 is hinged to the hinge seat 71 of the adjustment frame 7 via the hinge portion 41 .

[0056] Since the foot pedal 4 on current motorcycles is usually arranged on the frame 1, and in order to improve the handling performance, the frame 1 of current motorcycles generally adopts a lightweight design, which also leads to that the connection position of the foot pedal 4 on many motorcycles is relatively fixed, and it is also difficult to adjust the position of the foot pedal 4.

[0057] In this embodiment, a detachable adjustment frame 7 is provided, and an additional adjustment frame 7 is provided on the frame 1 to achieve the purpose of changing the position of the pedal 4. This solution can upgrade and transform the existing motorcycle frame 1 at a low cost and avoid wasting materials.

[0058] Moreover, since the adjusting frame 7 is detachable, when dealing with motorcycles of different specifications and sizes, different sizes of the adjusting frame 7 can be selected for assembly according to actual needs, which is more convenient for modifying the existing vehicle frame 1 and can better match the actual needs of the driver.

[0059] As Figures 1-4 shown, a connecting portion 72 is formed on the adjusting frame 7, and a first connecting hole 73 is formed in the connecting portion 72.

[0060] A connecting groove 11 is recessed and formed on the vehicle frame 1, and a second connecting hole 12 is formed in the connecting groove 11.

[0061] The connecting portion 72 can cooperate with the connecting groove 11 to facilitate the alignment of the first connecting hole 73 and the second connecting hole 12, so that the adjusting frame 7 can be bolted to the vehicle frame 1.

[0062] As Figures 1-4 shown, the edge of the connecting groove 11 is formed as a positioning side wall 13.

[0063] The peripheral contour of the connecting portion 72 matches the contour of the positioning side wall 13. When the connecting portion 72 is connected to the connecting groove 11, the periphery of the connecting portion 72 can abut against the positioning side wall 13. Since the contour of the positioning side wall 13 matches the peripheral contour of the connecting portion 72, it can help to position the vehicle frame 1 and the adjusting frame 7, making it easy to align the first connecting hole 73 and the second connecting hole 12 and facilitating assembly.

[0064] Specifically, as Figure 5 shown, a blocking portion 74 is also formed in the hinge seat 71.

[0065] An abutting convex block 46 is formed protruding from the end of the hinge portion 41.

[0066] When the footrest 4 is in the retracted state, the footrest 4 rotates upward and the upper end surface 45 of the footrest 4 fits against the side of the vehicle frame 1. At this time, the width of the motorcycle can be reduced, making it convenient to store or park the motorcycle.

[0067] When the footrest 4 is in the deployed state, the abutting convex block 46 abuts against the blocking portion 74, restricting the further rotation of the hinge portion 41. At this time, the driver can step on the footrest 4.

[0068] As Figures 1-6 shown, the hinge seat 71 is inclinedly arranged on the adjusting frame 7, and the angle E75 between the axis of the hinge seat 71 and the horizontal plane is 30° - 40°.

[0069] When the driver steps on the footrest 4 with their foot and applies force to the footrest 4, if only relying on the cooperation of the abutting bump 46 and the end of the hinge portion 41 for restriction, excessive pressure will be exerted on the abutting bump 46 and the end of the hinge portion 41, which is likely to cause the end of the abutting bump 46 or the hinge portion 41 to break. And if the footrest 4 becomes loose during driving, it is very easy for the driver to lose their balance instantly, resulting in an accident of the motorcycle tipping over.

[0070] And this technical solution is provided with an inclined footrest 4, and the position of the footrest 4 is offset towards the rear of the vehicle, so that the driver's leg steps on the footrest 4 obliquely. When the driver applies force to the footrest 4, the hinge portion 41 will move along the hinge shaft 47, and the hinge portion 41 can abut against one end of the hinge seat 71, so that the hinge seat 71 and the abutting bump 46 can cooperate to share the force generated when the driver steps on the footrest 4, thereby reducing the occurrence of the abutting bump 46 breaking.

[0071] A torsion portion 48 is formed on the hinge portion 41.

[0072] When the footrest 4 is connected to the hinge seat 71 through the hinge portion 41 and the footrest 4 is in the unfolded state, the upper end surface 45 of the footrest 4 can be kept upward through the torsion portion 48, or the footrest 4 can be deflected by 0° - 15°, so that the upper end surface 45 can face the direction of the vehicle head. Thus, when the driver is riding a motorcycle, the foot can be naturally placed on the footrest 4.

[0073] As Figures 1-6 shown, a seat 6 is also provided on the frame 1, and the upper surface of the seat 6 is formed into an arc;

[0074] The position of the hinge portion 41 is close to the rear end of the frame 1, and the projection of the hinge portion 41 on the horizontal plane deviates backward from the projection of the lowest point 61 of the upper surface of the seat on the horizontal plane by a deviation distance C42, and the length of the deviation distance C42 is 6 cm - 8 cm.

[0075] The angle D43 between the connecting line between the hinge portion 41 and the lowest point 61 of the upper surface of the seat and the vertical plane is 7° - 10°.

[0076] Through such a design, when the driver is riding a motorcycle, the position of the driver's foot on the footrest 4 can be closer to the rear of the motorcycle than the position of the driver's buttocks, which can further guide the driver to maintain a more reasonable riding posture when driving the motorcycle.

[0077] As Figures 1-6 shown, a plurality of anti-slip teeth 44 are convexly formed on the periphery of the footrest 4, and the anti-slip teeth 44 can provide additional friction when the driver steps on the footrest 4 to prevent the driver's foot from slipping.
