DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0039] Reference Figures 1-8 As shown in the drawings, the present application provides an air energy power vehicle with kinetic energy recovery, which comprises a vehicle body 2 and front and rear wheels 1 and 4 arranged on the front and rear of the vehicle body 2. In actual application, the vehicle body 2 is driven by the rear wheels, and the rear wheel 4 is the driving wheel. The vehicle body 2 is provided with a steering handle 5 for steering the front wheel 1, and is also provided with an air storage tank 6 for providing air power to drive the rear wheel 4. Through the above specific structural design, the air storage tank 6 provides driving force for the rotation of the rear wheel 4, which is known to those skilled in the art.

[0040] The steering handle 5 is provided with two wheel frame rods 7, and the front wheel 1 is arranged between the two wheel frame rods 7. The wheel frame rod 7 is provided with clamping control structure for clamping and controlling the rotation of the front wheel 1 relative to the wheel frame rod 7. The front wheel 1 is provided with a rotating inflation structure for inflating the air storage tank 6 under the condition of clamping and rotating relative to the wheel frame rod 7.

[0041] See the drawings Figure 5As shown, the front wheel 1 includes an inner wheel body 101 and an outer wheel body 110 arranged concentrically from the inside to the outside. A rotating inflation structure is disposed between the inner wheel body 101 and the outer wheel body 110.

[0042] This embodiment proposes a specific rotary inflation structure, which includes 8 or 10 slots 106 centered on the central axle 102 and formed on the outer edge of the inner wheel body 101. Specifically, the number of slots 106 is an even number, greater than six. Each slot 106 is provided with an inflation cylinder structure, and each inflation cylinder structure includes a piston rod 114. A guide wheel 115 is rotatably provided at one end of the piston rod 114 facing the outer side of the inner wheel body 101. A guide wheel groove 113 is formed on the inner side of the outer wheel body 110 for guiding the movement of the guide wheel 115. The inner contour of the guide wheel groove 113 is a regular heptagon. Through the above-described specific structural design, the two piston rods 114 and their guide wheels 115 are respectively aligned with the corners and sides of the regular heptagon inside the guide wheel groove 113. That is, when the two piston rods 114 move to the corner and side positions, the two piston rods 114 are respectively at the maximum extension stroke and the minimum retraction stroke. In subsequent changes, they can undergo corresponding extension and retraction changes to reduce the buffering of the extension and retraction changes of each piston rod 114.

[0043] See instruction manual attached Figure 5 , Figure 6 and Figure 7 As shown, an inflation chamber 122 is provided at the central axis of the inner wheel body 101. A ventilation channel is provided inside the central wheel axle 102. Several vent holes 103 are provided on the side wall of the central wheel axle 102 located inside the inflation chamber 122 for communicating with each other through the ventilation channel and the inflation chamber 122. One end of the air guide pipe 3 is rotatably and sealed to both ends of the central wheel axle 102. The other end of the air guide pipe 3 is connected to the air storage tank 6.

The gas duct connector 302 is rotatably connected to one end of the venting channel through a second bearing 303. A pipe fixing bracket 301 for fixing the gas duct connector 302 is fixedly installed on the wheel frame rod 7. A second one-way gas valve is installed on the gas duct 3 for one-way gas flow in the gas duct 3 and for gas flow from the inflation chamber 122 to the gas storage tank 6.

[0044] A support cylinder 703 is fixedly installed at one end of the wheel frame rod 7. A telescopic channel 701 is opened inside the wheel frame rod 7. One end of the telescopic channel 701 is connected to the inside of the support cylinder 703. An electric telescopic rod 702 is fixedly installed inside the telescopic channel 701. A slider 704 is fixedly installed at the push rod head of the electric telescopic rod 702 facing the inside of the support cylinder 703. A locking tooth 705 is provided on the side of the slider 704 facing the inside of the support cylinder 703. The central wheel shaft 102 is rotatably installed inside the support cylinder 703 through a third bearing 707. A toothed groove 706 is opened on the outer side of the central wheel shaft 102 located inside the support cylinder 703 along its circumferential direction for cooperating with the locking tooth 705.

[0045] The inflation cylinder structure includes a piston cylinder liner 107 fixedly installed in a groove 106. A mounting plate 116 is movably installed inside the piston cylinder liner 107. One side of the mounting plate 116 is fixedly connected to the end of the piston rod 114, and a piston 119 is installed on the other side of the mounting plate 116. A first one-way valve 123 is installed on the side of the piston cylinder liner 107 facing the outer wheel body 110. The side of the groove 106 facing the inflation chamber 122 is connected to the inflation chamber 122 through a spring recess 117, a connecting channel 124, and a contraction chamber 121 sequentially opened. A return spring 118 is installed in the spring recess 117. One end of the return spring 118 is fixedly connected to the piston 119, and the other end of the return spring 118 is fixedly connected to the inner end face of the spring recess 117. The inner contour of the contraction chamber 121 is shaped like a frustum of a cone, and an air cushion 120 is installed in the contraction chamber 121.

[0046] A rim 111 is provided along the outer edge of the outer wheel body 110, and a tire 112 is provided on the outer side of the rim 111. Protective covers 104 are provided on both sides between the central wheel axle 102 and the outer wheel body 110. In practical applications, the protective covers 104 are provided with several ventilation holes. An annular insert 109 is fixedly provided on the outer edge of the protective cover 104. An annular mounting groove 108 for embedding the annular insert 109 is provided on the outer wheel body 110. The annular insert 109 is fixedly connected to the outer wheel body 110 by bolts. A through-shaft hole is provided at the center of the protective cover 104. The inner side of the through-shaft hole is rotatably connected to the central wheel axle 102 by a first bearing 105.

[0047] In practical applications, when pressurizing the inflation chamber 122, as the guide wheel 115 moves from the corner to the middle of the edge of the guide wheel groove 113, the guide wheel 115 drives the mounting plate 116 and the piston 119 to slide within the piston cylinder liner 107 via the piston rod 114. In practical applications, the center points of the mounting plate 116 and the piston 119 are fixedly connected to each other. Therefore, when the mounting plate 116 moves upward, the piston 119 cannot be supported by the mounting plate 116, resulting in deformation and gas entering the chamber below the mounting plate 116. Conversely, when the mounting plate 116 moves downward, the piston 119 receives greater support from the mounting plate 116, and its outer edge seals against the inner wall of the piston cylinder liner 107. Similarly, a common piston structure in existing air pumps can be used, where a one-way valve is installed on the piston 119 while it remains in a sealed contact with the inner wall of the piston cylinder liner 107. At this time, the return spring 118 is in a compressed state, causing the piston 119 to inflate the air in the piston cylinder liner 107 toward the inflation chamber 122. The air cushion 120 is deformed toward the inflation chamber 122 by the airflow, achieving communication between the piston cylinder liner 107 and the inflation chamber 122. Meanwhile, the first one-way valve 123, under the negative pressure inside the piston cylinder liner 107, allows air to enter from the outside in. As the guide wheel 115 moves from the middle to the corner of the guide wheel groove 113, ... Under the elastic force of the return spring 118, the piston 119 and piston rod 114 are pushed to move toward the outer wheel body 110. At this time, the air pad 120 closes the port of the connecting channel 124. When the piston 119 is inside the piston cylinder liner 107 toward the outer wheel body 110, it is pushed by the air pressure inside the piston cylinder liner 107, and the outer edge of the piston 119 is deformed, thereby moving the gas inside the piston cylinder liner 107 toward the spring hole 117, thereby performing reciprocating inflation.

[0048] Working principle and effects of the invention:

[0049] The vehicle body 2 moves under the support of the front wheel 1 and the inner wheel body 101. The front wheel 1 has two usage states. In the first usage state, the front wheel 1 can rotate relative to the wheel frame rod 7 and is used as a normal wheel. In the second usage state, the front wheel 1 can be fixed relative to the wheel frame rod 7, and in this case, the front wheel 1 can be inflated into the air tank 6 through the air duct 3. The electric telescopic rod 702 push rod inside the wheel frame rod 7 extends, thereby driving the slider 704 to move telescopically within the telescopic channel 701. When the electric telescopic rod 702 push rod reaches its maximum stroke, the locking teeth 705 engage with the toothed groove 706 on the outer side of the central wheel axle 102, thereby locking the position of the central wheel axle 102 relative to the wheel frame rod 7. The electric telescopic rod 702 push rod inside the wheel frame rod 7 retracts. This drives the slider 704 to extend and retract within the telescopic channel 701. When the electric telescopic rod 702 pushes to its minimum stroke, the locking teeth 705 and the tooth groove 706 separate from each other, thereby enabling the central wheel axle 102 to rotate relative to the wheel frame rod 7. When the front wheel 1 is in the second usage state, as the front wheel 1 moves forward, the central wheel axle 102 and the wheel frame rod 7 are relatively locked, and the outer wheel body 110 rotates relative to the outer side of the inner wheel body 101, thereby enabling the guide wheel 115 to roll along the guide wheel groove 113. During this process, the piston rod 114 drives the mounting plate 116 and the piston 119 to extend and retract within the piston cylinder liner 107, thereby enabling the inflation chamber 122 to be filled with air. The gas in the inflation chamber 122 is added to the air storage tank 6 through the air guide pipe 3. More specifically, when the front wheel 1 is used in the first usage state, it is used for driving on flat roads and uphill driving. When the front wheel 1 is used in the second usage state, it is used for driving downhill and braking driving. In addition, the front wheel 1 can be suspended in the air and the air tank 6 can be filled by rotating the front wheel 1.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.

A method of using an air-powered vehicle with kinetic energy recovery, employing the air-powered vehicle with kinetic energy recovery as described in claim 4, characterized in that: Includes the following steps: S1: The vehicle body (2) moves under the support of the front wheel (1) and the inner wheel body (101). The front wheel (1) has two usage states. The first usage state is that the front wheel (1) can rotate relative to the wheel frame rod (7) and is used as a normal wheel. The second usage state is that the front wheel (1) can be fixed relative to the wheel frame rod (7). At this time, the front wheel (1) can be filled with air to the air tank (6) through the air guide pipe (3). S2: In step S1, the electric telescopic rod (702) push rod inside the wheel frame rod (7) extends, thereby driving the slider (704) to move telescopically within the telescopic channel (701). When the electric telescopic rod (702) push rod reaches its maximum stroke, the locking tooth (705) engages in the tooth groove (706) opened on the outside of the central wheel axle (102), thereby fixing the position of the central wheel axle (102) relative to the wheel frame rod (7). S3: In step S1, the electric telescopic rod (702) pusher in the wheel frame rod (7) retracts, thereby driving the slider (704) to move telescopically within the telescopic channel (701). When the electric telescopic rod (702) pusher reaches its minimum stroke, the locking teeth (705) and the tooth groove (706) separate from each other, thereby enabling the central wheel axle (102) to rotate relative to the wheel frame rod (7). S4: When the front wheel (1) is in the second use state, when the front wheel (1) moves forward, the position between the central wheel axle (102) and the wheel frame rod (7) is relatively locked, and the outer wheel body (110) rotates relative to the outer side of the inner wheel body (101), thereby realizing the guide wheel (115) rolling along the guide wheel groove (113). During this process, the piston rod (114) drives the mounting plate (116) and the piston (119) to move in and out of the piston cylinder liner (107), thereby realizing the inflation of the inflation chamber (122). The gas in the inflation chamber (122) is added to the air tank (6) through the air guide pipe (3).
