DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] As attached Figure 1 , 2 and attached Figure 4 As shown:

[0027] Embodiment 1: This embodiment provides a pneumatic bicycle, comprising a body 1 and a power-assisting mechanism 2; the body 1 comprises a seat post 101, a rear wheel 103 is mounted on the rear end of the seat post 101 through a frame 102, a rotating shaft 108 is arranged at the bottom of the seat post 101, a driving gear 105 and a driven gear 107 are movably mounted on the frame 102, an input end of the driving gear 105 is connected to an output end of the rotating shaft 108, an output end of the driven gear 107 is connected to the rear wheel 103, and the driving gear 105 and the driven gear 107 are movably mounted on the frame 102. They are connected by a transmission assembly 202; the power-assisting mechanism 2 includes a power-assisting gear 201 movably arranged on the frame 102, the power-assisting gear 201 is connected to the transmission assembly 202, a blade wheel 203 is arranged on the rear wheel 103, a burst-charging pump 204 is fixedly installed on the frame 102 at the rear end of the blade wheel 203, a piston rod 205 is movably arranged on the burst-charging pump 204, a movable block 207 is fixedly installed on the piston rod 205, and a connecting rod 208 is movably installed between the movable block 207 and the power-assisting gear 201.

[0028] The operation and use of the present application is the same as that of a traditional bicycle, and is suitable for riding on a road with a slope of less than 15 degrees, that is, sitting on the seat post 101 drives the rotating shaft 108 to rotate, and when the rotating shaft 108 rotates, it drives the driving gear 105 to rotate, and then drives the driven gear 107 to rotate through the transmission component 202, so as to transmit power to the rear wheel 103 through the driven gear 107, so that the driving device moves on the ground. During the process, the transmission component 202 drives the power-assisting gear 201 to rotate, and when the power-assisting gear 201 rotates, it transmits power to the movable block 207 through the connecting rod 208, and converts the rotational action of the power-assisting gear 201 into a horizontal linear circular back and forth movement of the movable block 207, thereby The piston rod 205 is pushed and pulled back and forth by the movable block 207. When the piston rod 205 is pushed, air is drawn into the explosive charging pump 204. When the piston rod 205 is pulled, the air in the explosive charging pump 204 is pushed out. The pushed out air is ejected toward the blade wheel 203 on the rear wheel 103, generating airflow to push the blade wheel 203 to rotate, thereby assisting the rotation of the rear wheel 103 and achieving a power-assisting effect. At the same time, the ejection of gas can also blow away dust and impurities on the rear wheel 103 to avoid these impurities from having a negative impact on riding movement, thereby improving the smoothness of riding, providing power while adding fun, so that the user can experience more comprehensive fun and convenience during riding.

[0029] The burst air pump is a specific type of air pumping device, which uses the principle of compressed air. Each time the piston is compressed, the air is pressed into the air storage space. When needed, the air can be released quickly. It can store and release air more efficiently, increase the speed and impact force of the air blown to the impeller 203, and thus improve the power-assisting effect.

[0030] As attached Figure 1 ,2 and attached Figure 3 As shown:

[0031] Specifically, both ends of the rotating shaft 108 penetrate the frame 102 and are fixedly mounted with cranks 106 , and pedals 109 are movably mounted on the cranks 106 .

[0032] The rider sits on the seat post 101 and alternately steps on the pedals 109 with both feet to rotate the shaft 108. The rotation of the shaft 108 directly drives the driving gear 105 installed on the frame 102. The driving gear 105 is connected to the driven gear 107 through the transmission assembly 202. The driven gear 107 transmits the rotational power to the rear wheel 103, thereby pushing the entire device to move on the ground.

[0033] As attached Figure 1 , 2 , 3 and attached Figure 4 As shown:

[0034] Specifically, the transmission assembly 202 includes transmission gears movably disposed on the frame 102 , the number of the transmission gears is an even number, and the driving gear 105 , the driven gear 107 and the power-assisting gear 201 are all meshed with the transmission gears.

[0035] An even number of transmission gears ensures uniform distribution and smooth transmission of power when meshing, and ensures that the final driven gear 107 rotates forward. Power is transmitted from the rotating shaft 108 via the driving gear 105, the transmission gear, the power assist gear 201, and the transmission gear to the driven gear, and finally drives the rear wheel 103, ensuring efficient operation of the overall power system.

[0036] As attached Figure 1 , 2 and attached Figure 3 As shown:

[0037] Specifically, an inclined rod 1011 is fixedly installed between the top of the frame 102 and the seat post 101 , a connecting rod 1012 is fixedly installed between the inclined rod 1011 and the frame 102 , and a reinforcing rod 1013 is provided between the rotating shaft 108 outside the driving gear 105 and the seat post 101 .

[0038] An inclined rod 1011 is fixedly installed between the top of the frame 102 and the seat post 101 to provide structural support, making the connection between the seat post and the frame more stable. The connecting rod 1012 between the inclined rod 1011 and the frame 102 further enhances the stability of the structure, ensuring the bending resistance and overall rigidity during use. The reinforcing rod 1013 arranged between the rotating shaft 108 on the outside of the driving gear 105 and the seat post 101 can further ensure the stability of the driving gear 105 and the rotating shaft, prevent excessive twisting and deformation of the rotating shaft during riding, and at the same time separate the rider's legs from the driving gear 105, thereby enhancing the rider's sense of control over the vehicle and safety during riding.

[0039] As attached Figure 5 As shown:

[0040] Specifically, a slide groove 2072 is provided on the vehicle frame 102 , a slider 2071 is fixedly mounted on the movable block 207 , and the slider 2071 is slidably connected to the slide groove 2072 .

[0041] When moving, the movable block 207 will slide in the slide groove 2072 through the slider 2071, thereby improving the movement stability and limiting the movement range of the movable block 207, so that the movable block 207 can perform lateral and longitudinal reciprocating motion within the corresponding movement range, thereby better converting the rotational force of the power-assisting gear 201 into effective linear motion, and pushing the piston rod 205 to complete the inflation process.

[0042] As attached Figure 1 , 2 and attached Figure 4 As shown:

[0043] Embodiment 2: A pneumatic bicycle, comprising a vehicle body 1 and a power-assisting mechanism 2; the vehicle body 1 comprises a seat post 101, a rear wheel 103 is mounted on the rear end of the seat post 101 through a vehicle frame 102, a rotating shaft 108 is arranged at the bottom of the seat post 101, a driving gear 105 and a driven gear 107 are movably mounted on the vehicle frame 102, an input end of the driving gear 105 is connected to an output end of the rotating shaft 108, an output end of the driven gear 107 is connected to the rear wheel 103, and a transmission line 108 is arranged between the driving gear 105 and the driven gear 107. The power-assisting mechanism 2 includes a power-assisting gear 201 movably arranged on the frame 102, the power-assisting gear 201 is connected to the transmission assembly 202, a blade wheel 203 is arranged on the rear wheel 103, a charging pump 204 is fixedly installed on the frame 102 at the rear end of the blade wheel 203, a piston rod 205 is movably arranged on the charging pump 204, a movable block 207 is fixedly installed on the piston rod 205, and a connecting rod 208 is movably installed between the movable block 207 and the power-assisting gear 201.

[0044] The operation and use of the present application is the same as that of a traditional bicycle, that is, sitting on the seat post 101 drives the rotating shaft 108 to rotate, and when the rotating shaft 108 rotates, it drives the driving gear 105 to rotate, and then drives the driven gear 107 to rotate through the transmission component 202, so as to transmit power to the rear wheel 103 through the driven gear 107, so that the driving device moves on the ground. During the process, the transmission component 202 drives the power-assisting gear 201 to rotate, and when the power-assisting gear 201 rotates, it transmits power to the movable block 207 through the connecting rod 208, and converts the rotation of the power-assisting gear 201 into a horizontal linear circular back and forth movement of the movable block 207, and then back and forth through the movable block 207. The piston rod 205 is pushed and pulled. When the piston rod 205 is pushed, air is drawn into the explosive charging pump 204. When the piston rod 205 is pulled, the air in the explosive charging pump 204 is pushed out. The pushed out air is ejected toward the blade wheel 203 on the rear wheel 103, generating airflow to push the blade wheel 203 to rotate, thereby assisting the rotation of the rear wheel 103 and achieving a power-assisting effect. At the same time, the ejection of gas can also blow away dust and impurities on the rear wheel 103 to avoid these impurities from having a negative impact on riding movement, thereby improving the smoothness of riding, providing power while also adding fun, so that the user can experience more comprehensive fun and convenience during riding.

[0045] The burst air pump is a specific type of air pumping device, which uses the principle of compressed air. Each time the piston is compressed, the air is pressed into the air storage space. When needed, the air can be released quickly. It can store and release air more efficiently, increase the speed and impact force of the air blown to the impeller 203, and thus improve the power-assisting effect.

[0046] As attached Figure 1 , 2 and attached Figure 3 As shown:

[0047] Specifically, both ends of the rotating shaft 108 penetrate the frame 102 and are fixedly mounted with cranks 106 , and pedals 109 are movably mounted on the cranks 106 .

[0048] The rider sits on the seat post 101 and alternately steps on the pedals 109 with both feet to rotate the shaft 108. The rotation of the shaft 108 directly drives the driving gear 105 installed on the frame 102. The driving gear 105 is connected to the driven gear 107 through the transmission assembly 202. The driven gear 107 transmits the rotational power to the rear wheel 103, thereby pushing the entire device to move on the ground.

[0049] Specifically, a one-way gear is provided between the rotating shaft 108 and the driving gear 105 , and a flywheel is provided between the driven gear 107 and the rear wheel 103 .

[0050] The rotation of the shaft 108 through the one-way gear will drive the driving gear 105 to rotate synchronously, and when the shaft 108 stops, the driving gear 105 can still continue to rotate by relying on the relationship, and will not be affected by the stop of the shaft 108 or the backward rotation of the shaft 108. The rotation of the driven gear 107 through the flywheel will drive the rear wheel 103 to rotate synchronously, and when the driven gear 107 stops, the rear wheel 103 can still continue to rotate by inertia. The bicycle can be kept in a gliding state when the rider does not apply a driving force, and the maximum moving speed of the bicycle in the gliding state is not limited by the rotation speed of the driven gear 107, which is convenient for people to use.

[0051] As attached Figure 1 , 2 , 3 and attached Figure 4 As shown:

[0052] Specifically, two groups of blade wheels 203 and explosive charging pumps 204 are provided, and the two groups of blade wheels 203 and explosive charging pumps 204 are respectively located on both sides of the rear wheel 103, and a connecting plate 206 is fixedly installed between the piston rods 205 of the two explosive charging pumps 204.

[0053] There are two sets of blade wheels 203 and two sets of explosive inflator pumps 204, which are located on both sides of the rear wheel 103. Such a design can ensure the uniformity and stability of the pneumatic device, and one set on each side can provide assistance and airflow in a balanced manner, avoiding imbalance caused by unilateral configuration.

[0055] Specifically, an inclined rod 1011 is fixedly installed between the top of the frame 102 and the seat post 101 , a connecting rod 1012 is fixedly installed between the inclined rod 1011 and the frame 102 , and a reinforcing rod 1013 is provided between the rotating shaft 108 outside the driving gear 105 and the seat post 101 .

[0056] An inclined rod 1011 is fixedly installed between the top of the frame 102 and the seat post 101 to provide structural support, making the connection between the seat post and the frame more stable. The connecting rod 1012 between the inclined rod 1011 and the frame 102 further enhances the stability of the structure, ensuring the bending resistance and overall rigidity during use. The reinforcing rod 1013 arranged between the rotating shaft 108 on the outside of the driving gear 105 and the seat post 101 can further ensure the stability of the driving gear 105 and the rotating shaft, prevent excessive twisting and deformation of the rotating shaft during riding, and at the same time separate the rider's legs from the driving gear 105, thereby enhancing the rider's sense of control over the vehicle and safety during riding.

[0057] As attached Figure 1 , 2, 4 and attached Figure 5 As shown:

[0058] Specifically, a baffle 104 is fixedly installed at the rear end of the frame 102 , and an air nozzle 209 is provided at the front end of the explosive charging pump 204 , and the air nozzle 209 corresponds to the blade wheel 203 .

[0059] The baffle 104 will protect the rear of the device to prevent the rider from causing the rear of the device to collide with the external structure when performing operations such as reversing, which may cause damage to the explosive charging pump 204. The air blown out of the explosive charging pump 204 will be precisely perpendicular to the blades of the blade wheel 203 under the guidance of the air nozzle 209, directly acting on the rotation of the blade wheel 203 to enhance its propulsion effect.

[0060] As attached Figure 5 As shown:

[0061] Specifically, a slide groove 2072 is provided on the vehicle frame 102 , a slider 2071 is fixedly mounted on the movable block 207 , and the slider 2071 is slidably connected to the slide groove 2072 .

[0062] When moving, the movable block 207 will slide in the slide groove 2072 through the slider 2071, thereby improving the movement stability and limiting the movement range of the movable block 207, so that the movable block 207 can perform lateral and longitudinal reciprocating motion within the corresponding movement range, thereby better converting the rotational force of the power-assisting gear 201 into effective linear motion, and pushing the piston rod 205 to complete the inflation process.

[0063] The transmission assembly 202 can be adjusted to a transmission chain, which is connected to the driving gear 105, the driven gear 107 and the power-assisting gear 201 at the same time. When the rotating shaft 108 rotates, it will drive the driving gear 105 to rotate, and the driving gear 105 will synchronously transmit power to the driven gear 107 and the power-assisting gear 201 through the transmission chain, so as to transmit power to the rear wheel 103 through the driven gear 107, and transmit power to the piston rod 205 through the power-assisting gear 201.
