Description

Technical Field

[0001] This invention relates to the field of bionic riding equipment technology, and more particularly to a fall protection safety component for recreational riding facilities. Background Technology

[0002] Recreational riding facilities, especially those with dynamic movements or high speeds, place high demands on rider safety. Traditional fall protection devices often employ fixed or manually adjustable seat belts and guardrails. Their tightness and coverage often cannot adaptively adjust to the rider's body shape and weight, resulting in issues such as poor fit, low comfort, or excessive restraint. Furthermore, existing protective components lack active protection functions. During operation, especially during lateral swaying or tilting, static wrapping protection alone cannot provide sufficient support, easily causing the rider's center of gravity to shift or even fall.

[0003] Specifically, current leg restraint mechanisms mostly rely on elastic bands or manual fastening, which cannot automatically trigger and adjust the restraint force based on the rider's weight the moment they sit down; while lateral protection structures mostly use rigid guardrails with fixed curvatures or simple inflatable cushions, which cannot adapt to the lateral wrapping needs of different body types, nor can they provide active compensation support when the rider's body leans to the side, resulting in the risk that the rider may still fall out of the protection range due to body displacement during dynamic processes. Summary of the Invention

[0004] Therefore, the present invention aims to provide a fall protection safety component that can adaptively trigger and adjust the protection state according to the rider's weight. This component automatically drives the leg strap mechanism and side guard mechanism by the weight of the rider, achieving a close-fitting and protective enclosure. At the same time, through mechanical linkage, the side guard mechanism and the ring handle on the handrail work together to actively provide lateral support when tilting to the side, thereby constructing an integrated, adaptive and responsive safety protection system, which significantly improves the fall protection safety and riding comfort of recreational riding facilities.

[0005] According to an embodiment of the present invention, a fall protection component for an entertainment riding facility includes a saddle, a backrest and a handrail are fixedly installed at the tail and head of the saddle, respectively, the saddle, the backrest and the handrail are all hollow, and leg-binding mechanisms are symmetrically arranged on both sides of the saddle. The backrest is equipped with a side protection mechanism, which includes two sets of side protection ribs symmetrically arranged on both sides of the backrest and multiple air cushion top blocks. The inner arc surface of the side protection ribs is provided with a sliding groove, and multiple slide seats are slidably installed in the sliding groove. The air cushion top blocks are located in the inner arc part of the side protection ribs and between two adjacent slide seats. A connecting rod is rotatably installed between each of the two adjacent slide seats and the air cushion top blocks. A synchronization rod is fixedly installed between two adjacent upper and lower slide seats. The slide seats near the root of the side protection ribs are fixedly set relative to the side protection ribs. A steel wire rope is fixedly connected between the fixed slide seats and the slidable slide seats. Pulling the steel wire rope causes the multiple sets of slide seats to move closer to each other with a variable pitch movement, and the air cushion top blocks are pushed out. A drive shaft is rotatably mounted inside the bottom of the saddle, and three first winding wheels are fixedly mounted on the drive shaft. The three first winding wheels are used to control the side guard mechanism and the two leg binding mechanisms, respectively.

[0006] Preferably, the bottom of the saddle is equipped with a plug and an adjustable locking strap for installation with the riding device. The saddle has a seat plate that can move vertically. A drive sleeve is fixedly installed at the bottom of the seat plate. The drive sleeve has a spiral guide groove. The drive shaft is movably inserted into the drive sleeve. The end of the drive shaft is provided with a protrusion that slides with the spiral guide groove. The up and down movement of the seat plate drives the drive shaft to rotate in both directions. A spring is connected between the top of the drive shaft and the seat plate for the seat plate to return to its original position.

[0007] Preferably, the leg-binding mechanism includes a first winding drum and a second winding drum. Both the first and second winding drums are fixedly mounted on the saddle. A small gear is fixedly mounted on the shaft of the first winding drum. A transmission box is integrally formed on the top of the first winding drum, and a large gear that meshes with the small gear is rotatably mounted inside the transmission box. A torsion spring is fixedly mounted between the shaft of the large gear and the bottom of the transmission box. A leg-binding strap is wound between the first and second winding drums. The shaft of the second winding drum adopts the same reduction gear set design as the first winding drum. A second winding wheel is fixedly mounted on the shaft of the large gear on the second winding drum. A steel wire rope is connected between the two second winding wheels and two of the first winding wheels.

[0008] Preferably, a ratchet is fixedly mounted on the shaft of the large gear on the second take-up drum, a positioning knob is rotatably mounted on the second take-up drum, a pawl adapted to the ratchet is fixedly mounted on the shaft of the positioning knob, and a spring is fixedly mounted between the positioning knob and the second take-up drum.

[0009] Preferably, the positioning knob is equipped with two spring pins, and the top of the second winding drum is provided with two arc-shaped guide grooves. The arc-shaped guide grooves are arranged clockwise along the rotation trajectory of the spring pins, and the ends of the arc-shaped guide grooves are provided with insertion holes that are adapted to the spring pins.

[0010] Preferably, the side guard ribs on both sides are staggered in the vertical direction, the side guard ribs are rotatably mounted on the backrest, a transmission gear is fixedly mounted on the shaft of the side guard rib, the backrest is provided with a cavity and openings are provided on both sides of the backrest, a U-shaped toothed plate is horizontally slidably mounted in the backrest, and the transmission gears on both sides are meshed with the U-shaped toothed plate through the openings.

[0011] Preferably, a steel wire rope is connected between the U-shaped toothed plate and one of the first winding wheels. The translation of the U-shaped toothed plate causes the side guard ribs on both sides to contract and open. A tension spring is fixedly installed between the U-shaped toothed plate and the inner wall of the backrest. Under the elastic force of the tension spring, the side guard ribs on both sides are always kept in the extended state.

[0012] Preferably, a ring-shaped handle is symmetrically slidably mounted on the handrail. The center of the ring-shaped handle has a through hole with a diameter larger than that of the steel wire rope, and the through hole is tapered. Multiple spring telescopic rods are symmetrically fixedly mounted in the middle of the handrail. A wedge-shaped head is fixedly mounted on the telescopic section of the spring telescopic rod. The wedge-shaped head can clamp the steel wire rope after being inserted into the through hole of the ring-shaped handle. A partition for reinforcing the spring telescopic rod is provided inside the handrail, and a spring is provided between the partition and the ring-shaped handle.

[0013] Preferably, the two steel wire ropes fixedly installed on the synchronizing rod are inserted into the inner sides of the guide rod in a staggered manner.

[0014] The beneficial effects of this invention are: 1. This invention adopts a dual-layer protection design, ensuring high safety: This invention constructs a dual-layer safety system consisting of a wrap-around basic protection and an active tilt protection. The first layer of protection is automatically triggered when the rider sits down, forming an adaptive and close-fitting constraint on the rider's thighs and the rear side of the torso through the leg straps and side guard ribs; the second layer of protection is actively triggered when the rider's body tilts to the side during the operation of the facility, through the linkage between the hands and the handrails, causing the air cushion top block of the side guard mechanism to be pushed out further and provide a rigid support point. The dual protection effectively prevents the risk of falling under static constraints and dynamic imbalance.

[0015] 2. This invention employs adaptive weight adjustment for seating, balancing safety and convenience: Utilizing the rider's own weight as the driving force, the mechanical linkage between the seat plate, spiral guide groove, and drive shaft directly converts the seating action into tightening power for the leg strap and side guard mechanisms. The greater the rider's weight, the greater the rotation angle of the drive shaft, resulting in adaptively enhanced restraint force and ensuring a snug and effective fit. When unattended, all mechanisms return to their open state under spring action, providing ample space for riders to get on and off, greatly improving ease of use. 3. The active tilt protection of this invention has a rapid response and does not interfere with each other: The ring handle and wedge head design inside the handrail constitute a sensitive tilt sensing and triggering mechanism. When the body tilts, the rider's sliding action of gripping the ring handle can automatically cause multiple wedge heads on the same side to retract radially, instantly locking the steel wire rope connected to the side protection mechanism, thereby triggering the active support function only on the tilted side. The response is rapid and direct. Due to the staggered arrangement of the steel wire ropes on both sides and the unidirectional action characteristic of the wedge heads, the mechanism on the side that has not tilted will not be falsely triggered. The protection on both sides is independent and precise, avoiding unnecessary linkage interference. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] For detailed implementation methods, please refer to... Figures 1-11 The present invention provides a fall protection component for recreational riding facilities, including a saddle 1, as shown in the reference. Figure 1 The saddle 1 has a backrest 3 and a handrail 5 fixedly installed at its rear and head, respectively. The saddle 1, backrest 3, and handrail 5 are all hollow. Leg-binding mechanisms 2 are symmetrically arranged on both sides of the saddle 1, and side guard mechanisms 4 are installed on the backrest 3. (See reference) Figure 4 A drive shaft 106 is rotatably mounted on the bottom of the saddle 1. Three first winding wheels 108 are fixedly mounted on the drive shaft 106. The three first winding wheels 108 are used to control the side guard mechanism 4 and the two leg binding mechanisms 2, respectively.

[0029] refer to Figure 5The bottom of the saddle 1 is equipped with a plug 101 and an adjustable locking strap 102 for installation with riding equipment. The saddle 1 is provided with a seat plate 103 that can move vertically. A drive sleeve 104 is fixedly installed at the bottom of the seat plate 103. A spiral guide groove 105 is provided on the drive sleeve 104. The drive shaft 106 is movably inserted into the drive sleeve 104. The end of the drive shaft 106 is provided with a protrusion 107 that slides and adapts to the spiral guide groove 105. The seat plate 103 moves up and down, driving the drive shaft 106 to rotate in the forward and reverse directions. A spring is connected between the top of the drive shaft 106 and the seat plate 103 for the seat plate 103 to return to its original position. The structure within this saddle can be considered a gravity-driven mechanism. Specifically, when the rider sits on the saddle 1, their weight presses down on the seat plate 103, causing it to move downwards. This movement drives the drive sleeve 104, fixed at its bottom, to move downwards simultaneously. Since the protrusion 107 at the end of the drive shaft 106 is engaged in the helical guide groove 105 of the drive sleeve 104, the downward-moving drive sleeve 104 applies force to the protrusion 107 through the wall of the helical guide groove 105, forcing the protrusion 107 to move along a helical trajectory. This, in turn, causes the drive shaft 106 to rotate, driving the saddle. The rotation of shaft 106 drives the three first winding wheels 108 fixed thereon to wind their respective steel wire ropes. This process realizes the core function of automatically converting the rider's weight as an input signal into mechanical driving force. When the rider leaves the saddle 1, the seat plate 103 returns to its original position under the restoring force of the spring, and the drive sleeve 104 rises accordingly. This reverses the rotation of the drive post 107 and drive shaft 106, causing the first winding wheels 108 to release the steel wire ropes. The various protection mechanisms then reset, and adaptive adjustment is achieved through the preset transmission ratio of the leg strap mechanism and the side guard mechanism 4.

[0030] refer to Figure 6 and Figure 7 The leg-binding mechanism 2 includes a first winding drum 201 and a second winding drum 205. Both the first winding drum 201 and the second winding drum 205 are fixedly installed on the saddle 1. A small gear 202 is fixedly installed on the shaft of the first winding drum 201. A transmission box is integrally formed on the top of the first winding drum 201, and a large gear 203 that meshes with the small gear 202 is rotatably installed inside the transmission box. A torsion spring 204 is fixedly installed between the shaft of the large gear 203 and the bottom of the transmission box. A leg-binding strap 206 is wound between the first winding drum 201 and the second winding drum 205. The shaft of the second winding drum 205 adopts the same reduction gear set design as the first winding drum 201. A second winding wheel 207 is fixedly installed on the shaft of the large gear 203 on the second winding drum 205. A steel wire rope is connected between the two second winding wheels 207 and two of the first winding wheels 108. When the drive shaft 106 inside the saddle 1 rotates, driving the first winding wheel 108 to tighten the wire rope, the tension of the wire rope acts on the second winding wheel 207. The rotation of the second winding wheel 207 is transmitted to the large gear 203 through its shaft. The large gear 203, through meshing with the small gear 202 (utilizing the transmission ratio to increase the winding speed while controlling the winding amplitude), transmits and decelerates the motion, driving the shaft of the second winding drum 205 to rotate, thereby starting to wind up the leg strap 206. At the same time, the internal structure of the first winding drum 201 is the same but the direction of action is complementary: the initial state of the large gear 203 is maintained by the torsion spring 204. When the leg strap 206 is tightened by the second winding drum 205, the first winding drum 201... The leg straps 206 are pulled out, causing the shaft of the first winding drum 201 to rotate. This rotation, via the small gear 202, drives the large gear 203 inside the drum to overcome the torque of the torsion spring 204 and deflect. This design allows the leg straps 206 on both sides to tighten together, wrapping around the rider's thighs from the front and back. The preload of the torsion spring 204 provides basic protective tightness, while the additional tightening force provided by the drive shaft 106 dynamically increases the restraint force according to the rider's weight, achieving adaptive adjustment. It is worth noting that the leg straps 206 are not locked after tightening; rather, the elasticity of the torsion spring 204 is used to increase the tightening force. In actual use, the leg straps 206 are not completely locked (to facilitate escape in case of an accident). refer to Figure 8 A ratchet 208 is fixedly mounted on the shaft of the large gear 203 on the second take-up drum 205. A positioning knob 209 is rotatably mounted on the second take-up drum 205. A pawl 210 adapted to the ratchet 208 is fixedly mounted on the shaft of the positioning knob 209. A spring spring 211 is fixedly mounted between the positioning knob 209 and the second take-up drum 205. Two spring pins 212 are mounted on the positioning knob 209. Two arc-shaped guide grooves 213 are opened on the top of the second take-up drum 205. The arc-shaped guide grooves 213 are set clockwise along the rotation trajectory of the spring pins 212, and the ends of the arc-shaped guide grooves 213 are opened with insertion holes adapted to the spring pins 212. This section provides manual locking and unlocking functions for the leg strap mechanism 2. After the automatic tightening process is completed, the pawl 210 automatically engages with the tooth groove of the ratchet 208 under the elastic force of the spring 211, preventing the large gear 203 and the second winding drum 205 from rotating in the opposite direction, thereby locking the leg strap 206 in the current tightened state to prevent accidental loosening during facility operation. When it is necessary to release the protection, the rider or operator can rotate the positioning knob 209 clockwise. Initially, the spring pin 212 slides along the arc-shaped guide groove 213. During rotation, the pawl 210 is driven to disengage from the ratchet 208 and unlock. At the same time, the leg strap 206 can be slightly loosened under the restoring force of the torsion spring 204 (at the first winding drum 201). When it rotates to the end of the arc-shaped guide groove 213, the spring pin 212 falls into the insertion hole under its own elastic force, temporarily locking the positioning knob 209 in the unlocked position, making it easy for the rider to get off. Under the elastic force of the spring spring 211, the mechanism can be reset by turning the positioning knob 209. The pawl 210 is ready to engage again under the action of the spring spring 211.

[0031] refer to Figures 9-10 The side guard mechanism 4 includes two sets of side guard ribs 401 symmetrically arranged on both sides of the backrest 3 and multiple air cushion top blocks 405. The inner arc surface of the side guard rib 401 has a sliding groove, and multiple slide blocks 404 are slidably installed within the groove. The air cushion top blocks 405 are located on the inner arc portion of the side guard rib 401 and between two adjacent slide blocks 404. A connecting rod 406 is rotatably installed between each adjacent slide block 404 and the air cushion top block 405. A synchronizing rod 407 is fixedly installed between two adjacent upper and lower slide blocks 404. The slide blocks 404 near the root of the side guard rib 401 are fixedly arranged relative to the side guard rib 401. A steel wire rope is fixedly connected between the fixed slide blocks 404 and the slidably arranged slide blocks 404. Pulling the steel wire rope causes the multiple sets of slide blocks 404 to move closer to each other with varying pitch, and the air cushion... The top block 405 is pushed out, and the side guard ribs 401 on both sides are staggered in the vertical direction. The side guard ribs 401 are rotatably mounted on the backrest 3. The transmission gears 402 are fixedly mounted on the shaft of the side guard ribs 401. The backrest 3 has a cavity and openings on both sides. A U-shaped toothed plate 403 is horizontally slidably mounted inside the backrest 3. The transmission gears 402 on both sides are meshed with the U-shaped toothed plate 403 through the openings. A wire rope is connected between the U-shaped toothed plate 403 and one of the first winding wheels 108. The translation of the U-shaped toothed plate 403 drives the side guard ribs 401 on both sides to contract and open. A tension spring is fixedly installed between the U-shaped toothed plate 403 and the inner wall of the backrest 3. Under the elastic force of the tension spring, the side guard ribs 401 on both sides are always kept in the extended state. The side guard mechanism 4 operates in two stages. The first stage involves the overall retraction of the side guard ribs 401: when the drive shaft 106 rotates, the corresponding first winding wheel 108 winds up the wire rope, pulling the U-shaped toothed plate 403 to overcome the tension spring and move horizontally towards the center of the backrest 3. The U-shaped toothed plate 403, through engagement with the transmission gears 402 on both sides, drives the side guard ribs 401 on both sides to rotate inward around their axis, from the initial unfolded state (e.g., ...). Figure 1 ) transforms into an inward-converging state (such as Figure 2 The side guards 401 initially surround the rider's torso from the side and rear, and the side guards 401 are designed to be staggered in the vertical direction to prevent them from colliding when retracted. The second stage involves the ejection and adaptive fitting of the air cushion top block 405. The tension of the corresponding steel cable acts on the movable slide 404, causing it to slide along the groove of the side guard rib 401 towards the root (towards the fixed slide 404). Since multiple slides 404 are linked by the synchronizing rod 407, they will move closer to each other synchronously. As the distance between the slides 404 decreases, the connecting rod 406 connecting the slides 404 and the air cushion top block 405 is squeezed, thereby pushing the air cushion top block 405 outwards from the inner arc surface of the side guard rib 401, so that the air cushion fits tightly against the sides of the rider's body, providing active lateral support and cushioning.

[0032] refer to Figure 11 A ring handle 501 is symmetrically slidably installed on the handrail 5. The center of the ring handle 501 has a through hole with a diameter larger than that of the wire rope and the through hole is tapered. Multiple spring telescopic rods 502 are symmetrically fixedly installed in the middle of the handrail 5. A wedge head 503 is fixedly installed on the telescopic section of the spring telescopic rod 502. The wedge head 503 can clamp the wire rope after being inserted into the through hole of the ring handle 501. A partition for reinforcing the spring telescopic rod 502 is provided in the handrail 5, and a spring is provided between the partition and the ring handle 501. Two wire ropes fixedly installed on the synchronizing rod 407 are inserted into the two sides of the handrail 5 in opposite directions. The ring grip 501 on the handrail 5 provides a linkage lateral support function. Under normal circumstances, the ring grip 501 is in its initial position on the outside of the handrail 5 under the action of its back spring. There is a gap between its tapered through hole and the steel cable from the synchronization rod 407. When tilting occurs, the rider grips the ring grip 501 on the handrail 5 with both hands, which will cause the ring grip 501 to slide left and right. Assuming a tilt to the right, the right ring grip 501 slides outward (to the right) along the handrail 5, and the left ring grip 501 slides inward (to the right) along the handrail 5. During the sliding process, the tapered through hole of the left ring grip 501 fits onto the tensioned steel cable and presses against the wedge head 503 of the spring telescopic rod 502 fixed to the inner wall of the handrail 5. Multiple wedge heads 503 on the inner wall of the ring grip 501 Under compression, the wire rope contracts towards the center, eventually clamping tightly onto the passing steel cable like a "clamp," allowing the steel cable to move. Since the other end of the steel cable is connected to the synchronizing rod 407 and air cushion block 405 of the side protection mechanism 4, clamping the steel cable is equivalent to rigidly connecting the rider's hands (via the ring grip 501) to the side protection mechanism 4 on the same side, thus triggering the active tilt protection support function in the side protection mechanism 4. The side protection rib 401 and air cushion block 405 become powerful support points when the rider tilts, effectively preventing further body displacement. The steel cables on both sides (the steel cables in this invention can be considered as bicycle brake cables; since this is existing technology, no further explanation is needed) are installed in opposite directions, ensuring that the corresponding steel cable can be effectively clamped when the ring grip 501 slides, regardless of whether the rider tilts to the left or right.

[0033] The working principle of this invention is a complete and automated process from "sensing body weight - adaptive basic constraint" to "sensing lateral tilt - dynamic linkage support". The entire process is passively triggered by the rider's weight and posture, without the need for electricity or manual operation. While providing all-round adaptive body constraints, it realizes the intelligent combination of safety protection and dynamic movement needs, significantly improving the safety and riding experience of recreational riding facilities.

[0034] Specifically, the following features are provided: 1. Convenient seating when no one is riding: When the component is in its initial standby state when no one is riding (e.g., Figure 1As shown), the seat plate 103 inside the saddle 1 is in its highest position under the restoring force of the spring; at this time, the protrusion 107 at the end of the drive shaft 106 is located at the top of the spiral guide groove 105 of the drive sleeve 104, the drive shaft 106 does not rotate, the three first winding wheels 108 fixed on it are in a relaxed state, and no tension is applied to any steel wire rope, the second winding wheel 207 in the leg strap mechanism 2 is not subjected to external force, and the leg strap 206 is in a relaxed or slightly pre-tightened state, leaving a spacious entry space for the rider's legs; in the side guard mechanism 4, the side guard ribs 401 on both sides are fully extended outward, providing the maximum lateral space for the rider to sit; the entire assembly is in an open and uninterrupted state, and the rider can sit down easily without any obstruction.

[0035] 2. Adaptive basic protection when someone is riding: After the rider sits down, their weight acts on the seat plate 103 of the saddle 1, causing it to move vertically downwards against the elastic force of the bottom spring. The drive sleeve 104 at the bottom of the seat plate 103 moves down synchronously, and the spiral guide groove 105 inside drives the convex post 107 that cooperates with it, forcing the drive shaft 106 to rotate. The rotation of the drive shaft 106 directly drives the three first winding wheels 108 fixed on it to rotate synchronously and wind the wire rope.

[0036] Adaptive triggering of leg restraint: Two steel wire ropes are respectively connected to the second winding wheels 207 on the left and right sides of the leg restraint mechanism 2. When the steel wire ropes are tightened, they pull the second winding wheels 207 to rotate. The rotation of the second winding wheels 207 is transmitted to the large gear 203 through its shaft. After meshing with the small gear 202 to reduce speed and increase torque, it drives the shaft of the second winding drum 205 to rotate, starting to forcefully wind up the leg restraint strap 206. At the same time, the first winding drum 201 on the other side is driven to rotate by the leg restraint strap 206, and drives the large gear 206 through the small gear 202 inside. 3. Overcoming the torsional rotation of the torsion spring 204 and storing elastic potential energy, the leg straps 206 tighten collaboratively from both the front and back sides of the rider's thighs. The tightening force consists of two parts: first, the preset basic tightness provided by the torsion spring 204 inside the first winding drum 201; and second, the additional tension transmitted and amplified by the rider's weight through the drive shaft 106, steel cable, and gear set. The greater the weight, the greater the rotation angle of the drive shaft 106, the greater the tightening of the steel cable, and the greater the constraint force ultimately applied to the leg straps 206, thus achieving adaptive adjustment of the tightening force according to weight. When the tightening action is completed, the pawl 210 automatically engages with the ratchet 208 under the action of the spring 211, locking the second winding drum 205 to prevent accidental loosening during operation and ensure that the thighs are reliably restrained.

[0037] The lateral enclosure is initially formed: a third steel wire rope is connected to the U-shaped toothed plate 403 of the side guard mechanism 4. This steel wire rope is wound by the first winding wheel 108, pulling the U-shaped toothed plate 403 to overcome its tension spring and move horizontally towards the center of the backrest 3. The movement of the U-shaped toothed plate 403 drives the left and right side guard ribs 401 to rotate inward around their mounting axis through the transmission gears 402 on both sides, from the fully extended state (e.g., Figure 1 ) transforms into an inward closing state (such as Figure 2 The system forms an initial arc-shaped enclosure from the side and rear of the rider's torso. The side guard ribs 401 on both sides are staggered in the vertical direction to ensure that they do not interfere with each other during the closing process. Thus, through the simple action of the rider sitting down, the system has automatically completed the basic constraint on the rider's lower body (thighs) and the initial enclosure on the upper body (side and rear of the torso), forming the first layer of adaptive safety protection.

[0038] 3. Active side tilt protection during intense riding: When centrifugal force or violent swaying occurs during the operation of amusement facilities, causing the rider's body to tilt to one side (e.g., to the left), the present invention can provide an active and linked second layer of dynamic protection.

[0039] Hand support and mechanism linkage trigger: When the body leans to the left, the rider will instinctively grip the handrail 5 to maintain balance. At this time, the left-side ring grip 501 is pressed to the left by the body and will slide to the right (inward) along the handrail 5. During the sliding process, the conical through hole of the ring grip 501 gradually compresses the wedge-shaped heads 503 of the multiple spring telescopic rods 502 inside. Under the compression of the conical hole wall, these wedge-shaped heads 503 overcome their own spring force and contract radially towards the center, tightly gripping the left-side steel cable passing through it like a "clamp". The other end of this steel cable is connected to the left-side side guard bar 401. After the steel cable is locked and fixed on the synchronizer rod 407 or movable slide 404, the support force applied by the rider through the ring grip 501 to resist lateral tilt is directly transmitted to the left side protection mechanism 4 through this steel cable. Since the wedge head 503 on the right side does not engage to lock the steel cable, the active lateral tilt protection function on the right side will not be triggered. Specifically, this pulling force will assist in driving the slide 404 to slide along the groove towards the root. The slide 404, through the connecting rod 406, further pushes the air cushion top block 405 outward, making it fit more closely to the rider's left torso, providing ample flexible support (such as...). Figure 3 As shown in the image, it provides a stable lateral support point for the rider's body, effectively resisting lateral tilting forces and preventing further body shift or even falling.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
