Description

Technical Field

[0001] This invention relates to the field of outdoor recreational equipment, and more particularly to a two-wheeled motorcycle for teenagers. Background Technology

[0002] Teen motorcycles (applicable to riders aged 18 and above) are a common type of outdoor recreational vehicle. These motorcycles are often ridden by riders in various complex terrains. Patent publication document CN220974430U discloses a two-wheeled outdoor motorcycle for teenagers. The engine of this motorcycle is connected to the rear wheel via a chain and sprocket. Unlike traditional road motorcycles, this type of motorcycle often needs to travel through shallow rivers and muddy areas. The use of a chain for transmission causes the chain to come into contact with water, resulting in excessively fast chain corrosion and a shortened lifespan of the entire motorcycle. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a two-wheeled motorcycle for teenagers. By using a pulley and belt for transmission, the motorcycle can be ridden on flooded roads, and the probability of jamming between the belt and pulley due to large foreign particles mixed in can be reduced, making riding safer and more reliable.

[0004] The technical solution adopted in this invention is as follows:

[0005] A two-wheeled motorcycle for teenagers includes a frame, a front wheel, and a rear wheel. The front wheel and the rear wheel are rotatably mounted on the frame. An engine is mounted on the frame. The motorcycle also includes a belt, pulleys, a spring, an auxiliary frame, and a tensioning block. Pulleys are provided on the output shaft of the engine and on the rear wheel. The belt and pulleys are engaged by toothed meshing. The auxiliary frame is fixedly mounted on the frame. A pin on the tensioning block is rotatably engaged with a shaft hole on the auxiliary frame. One end of the spring abuts against the auxiliary frame, and the other end of the spring abuts against the tensioning block. The spring has a tendency to spring the tensioning block towards the belt. One end of the tensioning block is provided with a serrated surface, which contacts the teeth on the belt.

[0006] In this type of two-wheeled motorcycle for teenagers, a pulley is installed on the rear wheel and a pulley is installed on the engine's drive shaft. The two pulleys are connected by a belt, which will not rust after being exposed to water. Therefore, it is very suitable as an accessory for off-road toy motorcycles.

[0007] Meanwhile, as an outdoor recreational vehicle, this type of two-wheeled motorcycle for teenagers can only guarantee a maximum engine speed of no more than 35 km / h. In addition, this type of two-wheeled motorcycle is not allowed to carry passengers and is only allowed to be ridden by one person.

[0008] In this type of motorcycle, because the vehicle needs to travel on unpaved surfaces such as grass and streams, foreign objects such as branches and weeds can easily get into the belt and pulley when traveling on such unpaved surfaces, causing the belt to jam and break. To avoid the aforementioned issues, an auxiliary frame is installed on the chassis, with a tensioning block flexibly mounted on it. The tensioning block contacts the teeth on the belt via its serrated surface. The belt teeth first contact the serrated surface and then mesh with the teeth on the pulley. Because the serrated surface of the tensioning block is pressed tightly against the belt teeth by the spring force, the belt can operate normally when there are no foreign objects between the belt and the serrated surface, or when the foreign objects are small. When relatively hard foreign objects, such as tree branches, are stuck on the belt, the spring force will cause the foreign object to become lodged between the serrated surface and the belt, slowing down the belt rotation and generating noise. This prevents the teeth on the belt and pulley from breaking, improving operational reliability and allowing the driver and passengers to stop and remove the object promptly. Furthermore, because the tensioning block is spring-loaded, it is freely movable, making it easy to remove foreign objects simply by moving the block. The contact between the serrated surface and the pulley teeth also reduces the probability of mud and sand adhering to the teeth.

[0009] In summary, this type of two-wheeled motorcycle uses a pulley and belt for transmission, allowing the motorcycle to be ridden on flooded roads. It also reduces the probability of jamming between the belt and pulley due to large particles of foreign matter, making riding safer and more reliable.

[0010] Optionally, a limiting opening is provided on the tensioning block, the limiting opening is located on one side of the sawtooth plane, and the pulley is located inside the limiting opening.

[0011] The function of the limiting port is to limit and guide the operation of the belt when it first comes into contact with the pulley, reducing the probability of the belt deviating and jamming.

[0012] Optionally, a brake disc is provided on the axle of the rear wheel, a brake caliper is provided on the frame, a brake pad is provided on the brake caliper, the brake disc is located between two brake pads, both sides of the brake disc are flat, and the brake disc is provided with circular and arc-shaped protrusions, which are used to contact the brake pads.

[0013] Because this type of motorcycle is used as an off-road motorcycle, when off-road motorcycles travel on streams or muddy roads, a water film will inevitably form on the flat brake disc. Once a water film forms, the brakes will be weak or even unable to stop. To avoid the above phenomenon, raised particles are further set on the brake disc. The raised particles are raised on a flat surface, so the probability of a water film forming at the raised particles is relatively low. At the same time, the raised particles can be embedded in the brake pads, which improves the reliability of braking and reduces the probability of the vehicle being weak or unable to stop when driving on water-crossing roads.

[0014] Optionally, the vehicle frame is equipped with an oil tank, an oil pump, and a water immersion sensor. The water immersion sensor and the oil pump are both electrically connected to the vehicle's engine on the vehicle frame. The oil pump is connected to the oil tank and the engine via pipes.

[0015] The function of the immersion sensor is to detect the water level. The immersion sensor is located at the vehicle's warning water level. When the vehicle is in a stream and the water level exceeds the vehicle's warning water level, the oil pump stops pumping oil, the engine brakes forcibly, and the vehicle can only be pushed or abandoned.

[0016] Optionally, it also includes a saddle, which is inserted into the frame, with a grip opening at one end and a foam block at the bottom.

[0017] The purpose of the saddle is to provide a seat for the rider. Since it is plugged into and fixed to the frame, the saddle can be removed from the frame. When the rider is resting outdoors, the saddle can be removed and used as a simple stool. The foam blocks provide insulation and improve comfort when used as a stool.

[0018] Optionally, the engine is equipped with an exhaust pipe, which is fixed to the frame. The exhaust pipe is located below the foam block, and the opening of the exhaust pipe does not contact the foam block, but faces the foam block.

[0019] Optionally, the vehicle may also include two electric telescopic rods, which are respectively located on both sides of the frame and arranged in a V-shape, with the front wheel and the rear wheel located between the two electric telescopic rods.

[0020] Two electric telescopic poles are installed in a V-shape to reduce the probability of beginners tipping over while learning to ride. Specifically, when beginners are learning to ride, the poles extend, reducing the distance between the poles and the ground. When a beginner is learning at a low speed and shows signs of tipping over, the poles will contact the ground first, reducing the probability of the user tipping over along with the motorcycle.

[0021] Optionally, the electric telescopic rod is provided with a support pad on its rod section. The support pad is made of soft rubber and is a trapezoidal block-shaped support pad.

[0022] The purpose of the support pad is to contact the ground. For example, when riding on an epoxy floor, the presence of a soft rubber support pad can reduce the probability of wear and tear on the epoxy floor.

[0023] Optionally, the frame is provided with a front bracket, the front wheel is rotatably mounted on the front bracket, a guard plate is rotatably mounted on the front bracket, and guard plates are distributed on both sides of the front wheel.

[0024] The skid plate has two states. The first state is parallel to the front support. When the skid plate is rotated, it can be made perpendicular to the front support. When the skid plate is perpendicular to the front support, the vehicle can flatten tall weeds encountered while off-roading, thus preventing weeds from causing injury to the vehicle and the rider's legs.

[0025] Optionally, the frame is provided with handlebars.

[0026] The beneficial effects of this invention are: by setting pulleys and belts for transmission, the entire motorcycle can be ridden on water-covered roads, and the probability of jamming between the belt and pulley due to the mixing of large foreign particles can be reduced, making riding safer and more reliable.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] As attached Figure 1 ~Appendix Figure 8As shown, a two-wheeled motorcycle for teenagers includes a frame 4, a front wheel 9, and a rear wheel 6. The front wheel 9 and the rear wheel 6 are rotatably mounted on the frame 4. An engine 15 is mounted on the frame 4. The motorcycle also includes a belt 5, pulleys 18, a spring, an auxiliary frame 16, and a tensioning block 17. The output shaft of the engine 15 and the rear wheel 6 are both provided with pulleys 18. The belt 5 and the pulleys 18 are engaged by tooth meshing. The auxiliary frame 16 is fixedly mounted on the frame 4. The pin 1703 on the tensioning block 17 is rotatably engaged with the shaft hole 1601 on the auxiliary frame 16. One end of the spring abuts against the auxiliary frame 16, and the other end of the spring abuts against the tensioning block 17. The spring has a tendency to spring the tensioning block 17 toward the belt 5. One end of the tensioning block 17 is provided with a serrated surface 1701, which contacts the teeth on the belt 5.

[0041] In this type of two-wheeled motorcycle for teenagers, a pulley 18 is installed on the rear wheel 6 and a pulley 18 is installed on the drive shaft of the engine 15. The two pulleys 18 are connected by a belt 5. The belt 5 will not rust after being exposed to water, so it is very suitable as an accessory for off-road toy motorcycles.

[0042] Meanwhile, as an outdoor recreational vehicle, this type of two-wheeled motorcycle for teenagers has an engine speed of 15 RPM that can only guarantee a maximum speed of no more than 35 km / h. In addition, this type of two-wheeled motorcycle is not allowed to carry passengers and is only allowed to be ridden by one person.

[0043] In this type of motorcycle, because the vehicle needs to travel on unpaved surfaces such as grass and streams, foreign objects such as branches and weeds can easily get into the belt 5 and pulley 18 when traveling on such unpaved surfaces, causing the belt 5 to jam and break. To avoid this, an auxiliary frame 16 is further installed on the frame 4, and a tensioning block 17 is elastically installed on the auxiliary frame 16. The tensioning block 17 contacts the teeth on the belt 5 through its own serrated surface 1701. The teeth on the belt 5 first contact the serrated surface 1701 and then mesh with the teeth on the pulley 18. Because the serrated surface 1701 on the tensioning block 17 is pressed against the teeth on the belt 5 under the elastic force of the spring, when no foreign objects are mixed in between the belt 5 and the serrated surface 1701 or the foreign objects themselves are small, the belt 5 can travel normally. When a relatively hard foreign object, such as a twig, gets stuck on the belt 5, the spring's elasticity causes the object to become lodged between the serrated surface 1701 and the belt 5. This slows the belt 5's rotation and generates noise, preventing the teeth on the belt 5 and pulley 18 from breaking, thus improving operational reliability and allowing drivers to stop and remove the object promptly. Furthermore, because the tensioning block 17 is spring-loaded, it is freely movable, making it easy to remove the foreign object simply by moving it. The contact between the serrated surface 1701 and the teeth of the pulley 18 also reduces the probability of dirt and sand adhering to the teeth.

[0044] In summary, this type of two-wheeled motorcycle uses pulley 18 and belt 5 for transmission, allowing the motorcycle to be ridden on flooded roads. It also reduces the probability of jamming between belt 5 and pulley 18 due to mixed large particles, making riding safer and more reliable.

[0045] As attached Figure 1 ~Appendix Figure 8 As shown, a limiting opening 1702 is provided on the tensioning block 17. The limiting opening 1702 is located on one side of the sawtooth plane 1701, and the pulley 18 is located inside the limiting opening 1702.

[0046] The function of the limiting port 1702 is to limit and guide the operation of the belt 5 when the belt 5 and the pulley 18 just start to contact, thereby reducing the probability of the belt 5 deviating and jamming during rotation.

[0047] As attached Figure 1 ~Appendix Figure 8 As shown, a brake disc 21 is installed on the axle of the rear wheel 6, a brake caliper 19 is installed on the frame 4, and a brake pad 20 is installed on the brake caliper 19. The brake disc 21 is located between the two brake pads 20. Both sides of the brake disc 21 are flat, and the brake disc 21 is provided with circular and arc-shaped protrusions 2101, which are used to contact the brake pads 20.

[0048] Because this type of motorcycle is used as an off-road motorcycle, when off-road motorcycles travel on streams or muddy roads, water film will inevitably form on the flat brake disc 21. Once water film forms, the brakes will be weak or even unable to stop. In order to avoid the above phenomenon, raised particles 2101 are further provided on the brake disc 21. The raised particles 2101 are raised on the flat surface, so the probability of water film forming at the raised particles 2101 is relatively low. At the same time, the raised particles 2101 can be embedded in the brake pads 20, which improves the reliability of braking and reduces the probability of the vehicle being weak or unable to stop when traveling on water-crossing roads.

[0049] As attached Figure 1 ~Appendix Figure 8 As shown, the frame 4 is equipped with an oil tank 13, an oil pump 14 and a water immersion sensor 12. The water immersion sensor 12 and the oil pump 14 are both electrically connected to the vehicle's engine on the frame 4. The oil pump 14 is connected to the oil tank 13 and the engine 15 through a pipe.

[0050] The function of the immersion sensor 12 is to detect the water level. The immersion sensor 12 is located at the vehicle's warning water level. When the vehicle is in the stream and the water level exceeds the vehicle's warning water level, the oil pump 14 stops pumping oil, the engine 15 brakes forcefully, and the bicycle can only be pushed or abandoned.

[0051] As attached Figure 1 ~Appendix Figure 8 As shown, it also includes a saddle 2, which is inserted into the frame 4. One end of the saddle 2 is provided with a grip opening, and a foam block is provided below the saddle 2.

[0052] The purpose of saddle 2 is to provide a seat for the rider. Since it is plugged into and fixed to the frame 4, saddle 2 can be removed from the frame 4. When the rider is resting outdoors, saddle 2 can be removed and used as a simple stool. The presence of foam blocks can serve two purposes: heat insulation and improved comfort when used as a stool.

[0053] As attached Figure 1 ~Appendix Figure 8 As shown, an exhaust pipe 3 is connected to the engine 15. The exhaust pipe 3 is fixed to the frame 4. The exhaust pipe 3 is located below the foam block, and the opening of the exhaust pipe 3 does not contact the foam block. The opening of the exhaust pipe 3 faces the foam block.

[0054] As attached Figure 1 ~Appendix Figure 8 As shown, it also includes an electric telescopic rod 11. There are two electric telescopic rods 11, which are respectively set on both sides of the frame 4 and are distributed in a figure-eight shape. The front wheel 9 and the rear wheel 6 are located between the two electric telescopic rods 11.

[0055] Two electric telescopic poles 11 are installed, and the electric telescopic poles 11 are distributed in a V-shape. This is to reduce the probability of beginners falling over when learning to ride. Specifically, when beginners are learning to ride, the poles of the electric telescopic poles 11 extend, and the distance between the poles and the ground decreases. When beginners are learning at a low speed and have a tendency to fall over, the poles will contact the ground first, reducing the probability that the user will fall over along with the motorcycle.

[0056] As attached Figure 1 ~Appendix Figure 8 As shown, the electric telescopic rod 11 has a support pad 10 on its rod. The support pad 10 is made of soft rubber and is a trapezoidal block.

[0057] The function of the support pad 10 is to contact the ground. For example, when riding on an epoxy floor, the presence of the soft rubber support pad 10 can reduce the probability of wear and tear on the epoxy floor.

[0058] As attached Figure 1 ~Appendix Figure 8 As shown, a front support 8 is provided on the frame 4, and the front wheel 9 is rotatably mounted on the front support 8. A guard plate 7 is rotatably provided on the front support 8, and guard plates 7 are distributed on both sides of the front wheel 9.

[0059] Specifically, the guard plate 7 has two states. The first state is parallel to the front support 8. When the guard plate 7 is rotated, it can be made to be perpendicular to the front support 8. When the guard plate 7 is perpendicular to the front support 8, the vehicle can flatten tall weeds encountered while off-roading, thereby preventing weeds from causing injury to the vehicle and the rider's legs.

[0060] As attached Figure 1 ~Appendix Figure 8 As shown, the handlebars 1 are mounted on the frame 4.

[0061] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
