Description

Technical Field

[0001] This invention relates to the field of automotive intelligent assisted driving test development technology, specifically a lightweight half-body target vehicle with a balloon liner. Background Technology

[0002] In the testing and development phase of autonomous and intelligent assisted driving for automobiles, target vehicles are needed to test the vehicle's sensing capabilities. Traditional half-body target vehicles are easily damaged in frequent and high-speed collisions. Traditional target vehicles generate huge inertia and reaction forces during collisions, and the front of the test vehicle and the sensors mounted on it may also be damaged or displaced. In addition, traditional heavy target vehicles are difficult to transport quickly. To address these issues, this invention proposes a lightweight half-body target vehicle. By using an optimized main balloon support to adapt to a lightweight trailer, the overall weight of the target vehicle is reduced, thereby significantly reducing the inertia and reaction forces generated during collisions, which also facilitates transportation.

[0003] Furthermore, after the test vehicle and the target vehicle collide, the test vehicle may not be able to stop in time. If the target vehicle remains stationary and obstructs the test vehicle, the continuous pressure between the test vehicle and the target vehicle may cause damage to the target vehicle. If the target vehicle automatically escapes immediately after the test vehicle and the target vehicle collide, the damage caused by the continuous contact between the test vehicle and the target vehicle can be avoided. Therefore, the present invention provides a lightweight half-body target vehicle with a balloon liner. Summary of the Invention

[0004] The purpose of this invention is to provide a lightweight balloon-lined half-body target vehicle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lightweight balloon-lined semi-vehicle target vehicle, comprising: The system consists of a front planar air cushion, a rear planar air cushion, and four horizontally placed cylindrical air columns fixed between the front and rear planar air cushions. The four cylindrical air columns are distributed at the four corners of the square of the front and rear planar air cushions. The front planar air cushion, the rear planar air cushion, and the cylindrical air columns are not connected to each other, and each of the front planar air cushion, the rear planar air cushion, and the cylindrical air columns is equipped with an independent air valve for air injection. Two lightweight bottom trailers are used to control the movement of the half-body target vehicle. The two lightweight bottom trailers are fixed on the cylindrical air column at the lower left position and the cylindrical air column at the lower right position, respectively. The lightweight bottom trailer includes a lightweight body, two parallel hollow shafts supporting the body, wheels fixedly sleeved at both ends of the hollow shafts, and a hollow support rod connecting the two hollow shafts. The exterior skin used to cover the half-body target vehicle, and the exterior skin displays the vehicle's exterior graphics; The rear sponge plate is fixed on the front flat air cushion, and a corner reflector is embedded in the rear sponge plate. The rear sponge plate is used to receive the impact of the test vehicle. A diverter is also provided between the front planar air cushion and the rear planar air cushion, as well as a base plate for supporting the diverter. The base plate is fixedly connected to the hollow support rod. The diverter alternately supplies air to the front planar air cushion, the rear planar air cushion, and the four cylindrical air columns. The diverter is also used to drive the impacted half-body target vehicle to escape.

[0006] The diverter includes a cylinder assembly fixed to the base plate, a fan assembly at one end of the cylinder assembly, a double axle driven by the fan assembly, and a pusher connected to the other end of the cylinder assembly. Each bottom light trailer has a hollow axle and a double axle fixedly connected to the end.

[0007] The flow divider also includes a flow-cutting device for regulating the output airflow in the cylinder device. The flow-cutting device includes an air plate, a main worm gear for driving the air plate to switch, a flow-cutting switch also provided on the air plate, a first kinetic energy tube connected between one end of the flow-cutting switch and the cylinder device, and a second kinetic energy tube connected between the other end of the flow-cutting switch and the impeller device. The air plate alternately establishes communication with the front planar air cushion, the rear planar air cushion and four cylindrical air columns.

[0008] The cylinder assembly includes a cylinder barrel, a piston disc that slides inside the cylinder barrel to push air, an air injection pipe that is fixedly connected to the bottom of the cylinder barrel, two conductive half-plates that penetrate the bottom plate of the cylinder barrel, and conductive concave plates that are used to contact and conduct electricity with the two conductive half-plates. The conductive concave plates are fixed on the piston disc, and the first kinetic energy tube is fixedly connected to the bottom of the cylinder barrel.

[0009] The pusher includes multiple pusher groups arranged in a ring around the opening of the cylinder barrel, a spring plate group for applying pressure to the pusher groups, an energy release group for driving the spring plate group to rotate, and an integrated frame fixed to the outside of the cylinder barrel. The main worm gear and the energy release group are connected by transmission.

[0010] The air plate includes an inner cylindrical cover fixed to one end of the main worm gear, an outer cylindrical cover that cooperates with the inner cylindrical cover to form a cylindrical box, an air outlet pipe that is fixedly connected to the outer cylindrical cover at one end, and multiple branch pipes that are connected around the outer cylindrical cover. The other end of the exhaust pipe is fixedly connected to the bottom of the cylinder barrel. A round hole is opened on the side shell of the inner barrel cover, and the inner barrel cover is rotated to allow the round hole to connect with each branch pipe in turn. The main worm gear supports the integrated frame.

[0011] The air plate also includes a hose fixedly connected to one end of the branch pipe, a pressure relief valve connected to one side of the branch pipe, and a C-shaped pipe connected to all the pressure relief valves. Each valve on the front flat air cushion, the rear flat air cushion, and the cylindrical air column corresponds to a branch pipe and is connected. One end of the C-shaped pipe opens the channel on the flow cut-off switch by exhausting air.

[0012] The wind turbine assembly includes a tail frame fixed on the cylinder barrel, a wind turbine shaft supported on the tail frame, a tail flat tube fixed at one end of the tail frame, a wind turbine impacted by the exhaust of the tail flat tube, and an output shaft that drives between the wind turbine shaft and the double axle. The second kinetic energy tube and the tail flat tube are fixedly connected.

[0013] The pusher assembly includes a split plate rack fixedly connected to the piston disc, a fixed plate frame fixed to the cylinder barrel, an L-shaped column rack that slides through a square hole in the fixed plate frame, a V-shaped plate fixed at one end of the L-shaped column rack, and a planetary gear set that drives between the split plate rack and the L-shaped column rack.

[0014] The spring plate assembly includes an L-shaped ring cylinder for spatial positioning, multiple unit columns evenly arranged around the L-shaped ring cylinder, and a U-shaped spring piece hinged to one end of each unit column. The U-shaped spring piece is fixed on the L-shaped ring cylinder, and some unit columns contact and press against the V-shaped plate.

[0015] The main worm gear drives the energy release group. After the energy release group is fully charged, it drives the L-shaped ring cylinder to rotate. The L-shaped ring cylinder rotates at a fixed angle to change the pressure of the V-shaped plate by different unit columns.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The balloon support is composed of a front flat air cushion, a rear flat air cushion, and a cylindrical air column, which reduces the weight of the entire target vehicle. The outer skin covers and wraps the entire target vehicle body to form a model of the rear of the vehicle. The balloon support can effectively absorb the impact energy of the test vehicle on the target vehicle. At the same time, it can rely on the sliding of the light trailer at the bottom to further reduce the damage to the half-body target vehicle and the test vehicle in the collision.

[0017] 2. The front planar air cushion, the rear planar air cushion, and the cylindrical air column of the present invention are all provided with independent air valves for air injection, which makes the main balloon support more durable and avoids the collapse of the entire balloon support due to a single air leak.

[0018] 3. The present invention also has an active escape protection function. After the test vehicle and the target vehicle collide accidentally, the diverter immediately drives the bottom light trailer to move, and the target vehicle actively moves away from the test vehicle, leaving braking space for the test vehicle, while protecting both the target vehicle and the test vehicle. In addition, during the test, the diverter alternately supplies air to the front planar air cushion, the rear planar air cushion and the four cylindrical air columns to ensure that the balloon support always maintains a full shape, thereby improving the accuracy and sensitivity of vehicle testing.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 17 The present invention provides a technical solution: a lightweight balloon-lined semi-vehicle target vehicle, comprising: The front planar air cushion 1, the rear planar air cushion 2, and four horizontally placed cylindrical air columns 3 fixed between the front planar air cushion 1 and the rear planar air cushion 2 are respectively distributed at the four corners of the square of the front planar air cushion 1 and the rear planar air cushion 2. The front planar air cushion 1, the rear planar air cushion 2 and the cylindrical air columns 3 are not connected to each other, and each of the front planar air cushion 1, the rear planar air cushion 2 and the cylindrical air columns 3 is provided with an independent air valve for air injection. Two bottom lightweight trailers 4 are used to control the movement of the half-body target vehicle. The two bottom lightweight trailers 4 are fixed on the cylindrical air column 3 at the lower left position and the cylindrical air column 3 at the lower right position, respectively. The bottom lightweight trailer 4 includes a lightweight body 401, two parallel hollow shafts 402 supporting the body, wheels 403 fixedly sleeved at both ends of the hollow shafts 402, and a hollow support rod 404 connecting the two hollow shafts 402. The exterior skin 5 is used to wrap the exterior of the half-body target vehicle, and the exterior skin 5 displays the vehicle's exterior graphics. The rear sponge plate 6 is fixed on the front flat air cushion 1, and the corner reflector 7 is embedded in the rear sponge plate 6. The rear sponge plate 6 is used to receive the impact of the test vehicle. A diverter 8 is also provided between the front planar air cushion 1 and the rear planar air cushion 2, as well as a base plate 9 for supporting the diverter 8. The base plate 9 and the hollow support rod 404 are fixedly connected. The diverter 8 supplies air to the front planar air cushion 1, the rear planar air cushion 2 and the four cylindrical air columns 3 in turn. The diverter 8 is also used to drive the impacted half-body target vehicle to escape.

[0039] The target vehicle's main balloon support has two trapezoidal planar air cushions with independent valves at the front and rear, namely the front planar air cushion 1 and the rear planar air cushion 2. Four cylindrical air columns with independent valves are distributed in the middle: the upper left cylindrical air column 3, the upper right cylindrical air column 3, the lower left cylindrical air column 3, and the lower right cylindrical air column 3. When subjected to an impact force from the front planar air cushion 1, the four cylindrical air columns 3 can effectively absorb the impact force through deformation, protecting the target vehicle and the test vehicle.

[0040] Each side is equipped with a bottom lightweight trailer 4, which is respectively attached to the cylindrical air column 3 at the lower left and the lower right positions. The lightweight body 401 is made of lightweight black foam material. The bottom lightweight trailer 4 is equipped with four wheels 403. The lightweight body 401 has slots on both sides to accommodate hollow support rods 404. The ends of the hollow support rods 404 are fixed with connectors. The hollow shaft 402 is movably sleeved in the through hole opened on the connector. The hollow support rods 404 and the hollow shaft 402 cooperate to support the lightweight body 401 and prevent the foam material from deforming. The lightweight body 401 has a circular groove to accommodate the cylindrical air column 3.

[0041] The design of the lightweight vehicle body 401 perfectly matches the cylindrical air column 3 at the lower left and lower right positions, ensuring that the distance between the vehicle body and the ground after installation is no more than 70mm, thus satisfying the simulation realism of the entire target vehicle. The two bottom lightweight trailers 4 lift the entire half-vehicle target vehicle to move, which can prevent the balloon support from being damaged by friction with the ground.

[0042] The shape of the rear foam plate 6 is designed with reference to the recommended shape in "ENCAP TEST PROTOCOL – AEB systems Version 1.0".

[0043] The assembled half-body target vehicle is lightweight and can be easily carried and pushed by two people. The reaction force generated upon impact is less than that of traditional half-body target vehicles that use metal trailers, thus effectively protecting the target vehicle and the test vehicle.

[0044] refer to Figure 6 Understandably, the diverter 8 includes a cylinder assembly 10 fixed on the base plate 9, a fan assembly 11 provided at one end of the cylinder assembly 10, a double axle 12 driven by the fan assembly 11, and a pusher 13 connected to the other end of the cylinder assembly 10. Each bottom light trailer 4 has a hollow shaft 402 and a double axle 12 fixedly connected to the end.

[0045] refer to Figure 7 It is understood that the flow divider 8 also includes a flow cutting device 14 for regulating the output airflow in the cylinder device 10. The flow cutting device 14 includes an air disc 15, a main worm gear 16 for driving the air disc 15 to switch, a flow cut-off switch 17 also provided on the air disc 15, a first kinetic energy tube 18 connected between one end of the flow cut-off switch 17 and the cylinder device 10, and a second kinetic energy tube 19 connected between the other end of the flow cut-off switch 17 and the impeller device 11. The air disc 15 alternately establishes communication with the front planar air cushion 1, the rear planar air cushion 2 and the four cylindrical air columns 3.

[0046] refer to Figure 8 The cylinder assembly 10 includes a cylinder barrel 20, a piston disc 21 that slides inside the cylinder barrel 20 to push air, an air injection pipe 22 that is fixedly connected to the bottom of the cylinder barrel 20, two conductive half-pieces 23 that penetrate the bottom plate of the cylinder barrel 20, and conductive concave pieces 24 that are in contact with the two conductive half-pieces 23 to conduct electricity. The conductive concave pieces 24 are fixed on the piston disc 21, and the first kinetic energy tube 18 is fixedly connected to the bottom of the cylinder barrel 20.

[0047] refer to Figure 9 Understandably, the pusher 13 includes multiple pusher groups 25 arranged around the opening of the cylinder barrel 20, a spring plate group 26 for applying pressure to the pusher groups 25, an energy release group 27 for driving the spring plate group 26 to rotate, and an integrated frame 28 fixed to the outside of the cylinder barrel 20. The main worm gear 16 and the energy release group 27 are connected by a transmission.

[0048] refer to Figure 10 Understandably, the air plate 15 includes an inner cylindrical cover 35 fixed to one end of the main worm gear 16, an outer cylindrical cover 34 that cooperates with the inner cylindrical cover 35 to form a cylindrical box, an air outlet pipe 29 that is fixedly connected to the outer cylindrical cover 34 at one end, and multiple branch pipes 33 that are connected around the outer cylindrical cover 34. The other end of the exhaust pipe 29 is fixedly connected to the bottom of the cylinder barrel 20. A circular hole is opened on the side shell of the inner cylindrical cover 35, and the inner cylindrical cover 35 is rotated so that the circular hole is connected to each branch pipe 33 in turn. The main worm gear 16 supports the integrated frame 28. Specifically, the main worm gear 16 is movably sleeved in the through hole opened on the integrated frame 28. One end of the main worm gear 16 is externally connected to the existing motor drive mechanism, and then the main worm gear 16 drives the inner cylindrical cover 35 to rotate.

[0049] The air plate 15 also includes a hose 30 fixedly connected to one end of the branch pipe 33, a pressure relief valve 32 connected to one side of the branch pipe 33, and a C-shaped pipe 31 connected to all the pressure relief valves 32. Each valve on the front flat air cushion 1, the rear flat air cushion 2 and the cylindrical air column 3 is connected to a branch pipe 33. One end of the C-shaped pipe 31 opens the channel on the control flow cut-off switch 17 by exhausting.

[0050] The interruptor switch 17 includes an F-shaped post 173 that extends and retracts at the port of the C-shaped tube 31, a spring assembly 174 for resetting the F-shaped post 173, a door plate 172 fixed at one end of the F-shaped post 173, a plate box 171 slidably penetrated by the door plate 172, and a pinhole post 175 fixed at the port of the C-shaped tube 31. The plate box 171 is fixedly connected between the first kinetic tube 18 and the second kinetic tube 19. A plate hole is opened in the middle of the door plate 172, and the door plate 172 slides to make the plate hole and the channel inside the plate box 171 unobstructed, so that air flows between the first kinetic tube 18 and the second kinetic tube 19. Since the F-shaped post 173 does not extend from the C-shaped tube 31, the F-shaped post 173 will not push the door plate 172. The plate body on the door plate 172 blocks the channel between the plate box 171, so that the air in the cylinder barrel 20 will not be discharged through the first kinetic tube 18. (Refer to the attached instruction manual.) Figure 11 Understandably, a pinhole is made in the middle of the pinhole column 175 to slowly release air, so that the F-shaped column 173 can retract into the C-shaped tube 31 after impact. Refer to the attached instruction manual. Figure 10 It is understood that an excess air vent is also opened at the port of C-tube 31. If too much air is vented out of C-tube 31, after the airflow impacts F-post 173, F-post 173 slides out and exposes the air vent, so that the air in C-tube 31 can be discharged through the vent.

[0051] The air injection pipe 22 is externally connected to the air injection mechanism in the prior art. The power switch is activated by the contact between the conductive half 23 and the conductive concave 24. After the conductive concave 24 and the two conductive half 23 are in contact, the power will discharge for a specified time, regardless of whether they are subsequently separated. The power supply supplies power to the air injection mechanism, so that the air injection mechanism injects a specified amount of air into the air injection pipe 22. This part of the air is replenished into the cylinder barrel 20. The piston disc 21 is subjected to elastic thrust from the spring disc assembly 26, causing it to tend to move towards the bottom of the cylinder barrel 20. The gas in the cylinder barrel 20 has output pressure. As mentioned earlier, the circular holes on the inner cylinder cover 35 are alternately connected to different branch pipes 33. This allows the cylinder barrel 20 to alternately connect with the front flat air cushion 1, the rear flat air cushion 2, and the four cylindrical air columns 3. For example, if the passage between the cylinder barrel 20 and the front flat air cushion 1 is unobstructed, the side shell on the inner cylinder cover 35 will block other passages. If the air in the front flat air cushion 1 decreases due to thermal expansion and contraction, or if minor damage causes some air leakage, the air in the front flat air cushion 1 needs to be replenished. Air is introduced, so that the air in the cylinder barrel 20 is pushed out by the piston disc 21. The air is injected into the outer cylindrical cover 34 through the exhaust pipe 29, and then discharged through the branch pipe 33 with the port not blocked. Subsequently, it is injected into the front flat air cushion 1 through the hose 30. If the front flat air cushion 1 is saturated with air, even if a channel is established between the cylinder barrel 20 and the front flat air cushion 1, air cannot be injected. That is, the cylinder barrel 20 is connected to the front flat air cushion 1, the rear flat air cushion 2, and the cylindrical air column 3 in turn. Air is delivered only when there is a space where air is lacking. In this way, the front flat air cushion 1, the rear flat air cushion 2, and the cylindrical air column 3 can all maintain a full shape.

[0052] During the testing and development of autonomous and intelligent assisted driving systems, the test vehicle gradually moves closer to the stationary target vehicle. If the test vehicle accidentally collides with the target vehicle, the front planar air cushion 1, rear planar air cushion 2, and cylindrical air column 3 on the target vehicle may deform, forcibly squeezing out the internal gas. During the test, the circular hole on the side shell of the inner cylindrical cover 35 is not connected to any branch pipe 33. Thus, the only outlet for exhaust from the front planar air cushion 1, rear planar air cushion 2, and cylindrical air column 3 is the pressure relief valve 32. The pressure relief valve 32 is a pressure relief valve in existing technology; when the pressure is sufficient, it will exhaust air into the C-shaped pipe 31. As mentioned earlier, the air exhausted into the C-shaped pipe 31 will impact the control flow cut-off switch 17, opening its own channel. This connects the first kinetic energy pipe 18 and the second kinetic energy pipe 19, allowing the air in the cylinder barrel 20 to be exhausted through the first kinetic energy pipe 18 to the second kinetic energy pipe 19, thus driving the subsequent airflow. The wheel device 11, and then the double axle 12 rotate to cause the two bottom light trailers 4 to move, controlling the half-body target vehicle to move away from the test vehicle. Because after the test vehicle and the target vehicle collide, the test vehicle may not stop in time. In this way, the target vehicle moves in the direction of the test vehicle. If the target vehicle and the test vehicle separate, or the target vehicle no longer positions to block the test vehicle, reducing the contact pressure between the test vehicle and the target vehicle, the target vehicle and the test vehicle can be protected. After the pressure relief valve 32 receives sufficient exhaust pressure from the branch pipe 33, the gas in the branch pipe 33 will be discharged through the pressure relief valve 32. When the front flat air cushion 1, the rear flat air cushion 2 and the cylindrical air column 3 are not subjected to external deformation pressure, the pressure relief valve 32 will not exhaust into the C-shaped pipe 31. The alternating air replenishment process of the front flat air cushion 1, the rear flat air cushion 2 and the cylindrical air column 3 will not cause air leakage. That is, the air output pressure in the cylinder barrel 20 is less than the critical exhaust pressure required by the pressure relief valve 32.

[0053] The wind turbine assembly 11 includes a tail frame 37 fixed on the cylinder barrel 20, a wind turbine shaft 39 supported on the tail frame 37, a tail flat tube 36 fixed at one end of the tail frame 37, a wind turbine 38 impacted by the exhaust of the tail flat tube 36, and an output shaft 40 that drives between the wind turbine shaft 39 and the double axle 12. The second kinetic energy tube 19 and the tail flat tube 36 are fixedly connected.

[0054] As previously mentioned, the exhaust from the second kinetic energy pipe 19 will subsequently cause the dual axles 12 to rotate. Specifically, the gas in the second kinetic energy pipe 19 is injected into the tail flat pipe 36, and then the gas is discharged and impacts the impeller 38. The impeller 38 drives the impeller shaft 39 to rotate. The impeller shaft 39 is movably sleeved in the through hole opened on the tail frame 37. One end of the lead-out shaft 40 is driven by a fixed bevel gear to change direction with the bevel gear fixed at the end of the impeller shaft 39. The other end of the lead-out shaft 40 is driven by a fixed bevel gear to mesh with the ring bevel gear fixed on the dual axles 12. A support plate is provided on one side of the underframe plate 9, and the lead-out shaft 40 is movably sleeved in the through hole opened on the support plate.

[0055] The push assembly 25 includes a split-plate rack 41 fixedly connected to the piston disc 21, a fixed plate frame 43 fixed to the cylinder barrel 20, an L-shaped column rack 44 sliding through a square hole in the fixed plate frame 43, a V-shaped plate 45 fixed at one end of the L-shaped column rack 44, and a planetary gear set 42 that transmits power between the split-plate rack 41 and the L-shaped column rack 44. The planetary gear set 42 amplifies the stroke. The planetary gear set 42 includes a sector-shaped moving plate 423, a second shaft 424 vertically fixed at one end of the sector-shaped moving plate 423, a first shaft 422 with an arc-shaped rack on the sector-shaped moving plate 423 engaging with the first shaft 422, and a disc gear 421 fixed at one end of the first shaft 422. (Refer to the attached instruction manual.) Figure 13 Understandably, the V-shaped plate 45 is pressed and moves to the left, causing the L-shaped column rack 44 to move to the left and drive the shaft gear fixed at the end of the second shaft 424 to rotate. Then, through 432, it drives the shaft gear fixed at the end of the first shaft 422 to rotate. Subsequently, the disc gear 421 rotates, causing the plate rack 41 to move. The plate rack 41 then drives the piston disc 21.

[0056] The spring plate assembly 26 includes an L-shaped ring cylinder 47 with spatial positioning, a plurality of unit columns 46 evenly arranged around the L-shaped ring cylinder 47, and a U-shaped spring piece 48 that is hinged to one end of each unit column 46. The U-shaped spring piece 48 is fixed on the L-shaped ring cylinder 47, and some of the unit columns 46 contact and press against the V-shaped plate 45.

[0057] The main worm gear 16 drives the energy release group 27. After the energy release group 27 is fully charged, it drives the L-shaped ring cylinder 47 to rotate. The L-shaped ring cylinder 47 rotates at a fixed angle to change different unit columns 46 to press the V-shaped plate 45.

[0058] The energy release assembly 27 includes an inner frame 276 fixed on an integrated frame 28, a constricted inner cylinder 275 supported on the inner frame 276, an annular spring 274 with an outer fixing sleeve on the constricted inner cylinder 275, an outer ring gear 273 with an outer fixing sleeve on the annular spring 274, an inner clip 278 that slides through a square hole in the inner frame 276, an inner pressure spring 277 for applying elastic force to the inner clip 278, and a side shaft 271 and a control worm gear 272 that are respectively movably sleeved in two through holes in the inner frame 276. The outer ring gear 273 clamps an annular groove on the outer wall of the constricted inner cylinder 275 by fixing two symmetrical bow-shaped columns. One end of the side shaft 271 is connected to the outer ring gear by a fixed gear. The gear 273 is engaged in a transmission connection. The other end of the side shaft 271 is driven by a fixed bevel gear to change direction with a bevel gear fixed at one end of the control worm 272. One end of the constricted inner cylinder 275 is engaged in a transmission with the main worm 16 through a fixed worm wheel. The control worm 272 is engaged in a transmission with a worm wheel fixed at one end of the L-shaped ring cylinder 47. One end of the inner frame 276 is fitted into an annular groove on the inner wall of the constricted inner cylinder 275 by a C-shaped plate. The other end of the inner frame 276 is fitted into an annular groove on the inner wall of the L-shaped ring cylinder 47 by a C-shaped plate. The inner pressure spring 277 is fixed on the inner frame 276. The inner clip 278 is fitted into a V-shaped groove on the inner wall of the outer ring cylinder gear 273 by a pointed tip. Further explanation of the coordinated functions of the pusher group 25, the spring plate group 26, and the energy release group 27: The rotation of the main worm gear 16 also drives the inner cylinder 275 to rotate, which in turn causes the annular spring 274 to contract and store energy. Once sufficient energy is stored, it breaks the inner clamp 278's hold on the outer ring gear 273, allowing the outer ring gear 273 to rotate. The annular spring 274 releases power once, causing the outer ring gear 273 to rotate one revolution. The outer ring gear 273 drives the side shaft 271, which in turn causes the control worm gear 272 to rotate a specified number of revolutions. The control worm gear 272 further drives the L-shaped ring cylinder 47, thus rotating the L-shaped ring cylinder 47 by a fixed angle. (Refer to the attached instruction manual.) Figure 14 Understandably, three unit columns 46 contact and press against the V-shaped plate 45. After the unit columns 46 rotate a small angle, three new unit columns 46 translate and contact the V-shaped plate 45. The unit columns 46 that were originally in contact translate away. Each unit column 46 is controlled by a U-shaped spring 48, that is, there are three U-shaped springs 48 to apply elastic force to one V-shaped plate 45. By replacing the unit columns 46, new U-shaped springs 48 are replaced to apply elastic force. This is to deal with the bending fatigue problem of the U-shaped springs 48 caused by the repeated axial movement of the unit columns 46.

[0059] Instruction manual attached Figure 8 and attached Figure 9The image shows the piston disc 21 completely embedded in the frame. During normal operation, the cylinder barrel 20 is filled with air, and the piston disc 21 is located at the port of the cylinder barrel 20. As the piston disc 21 slides towards the port of the cylinder barrel 20, it drives the splitter rack 41, thus... Figure 13 The split-plate rack 41 slides to the right, which, through the planetary gear set 42, causes the L-shaped column rack 44 to slide to the right, thereby attaching... Figure 14 The V-shaped plate 45 moves to the right to press the unit column 46. The axial movement of the unit column 46 to the right will cause the U-shaped spring 48 to deform. In this way, multiple U-shaped springs 48 apply elastic force to the piston disc 21. The U-shaped springs 48 are in a state of tension. Over time, they will experience elastic fatigue and reduced elasticity. Alternatively, the intake and exhaust of air in the cylinder barrel 20 will cause the piston disc 21 to slide, resulting in frequent deformation of the U-shaped springs 48 that apply elastic force. This will also cause elastic fatigue and softening of the U-shaped springs 48. Therefore, the L-shaped ring cylinder 47 in this invention replaces the U-shaped springs 48 with new ones by rotating periodically to apply elastic force. The replaced U-shaped springs 48 rest and recover their vitality.
