Description

Technical Field

[0001] This invention relates to the field of transportation safety protection technology, specifically to an environmentally friendly transportation safety protection device. Background Technology

[0002] As the concept of environmentally friendly travel gains popularity, light and environmentally friendly vehicles such as bicycles and electric bicycles have become an important choice for short-distance travel, and their frequency of carrying passengers such as children and the elderly is increasing. However, the corresponding safety protection technology for rear-seat passengers has lagged behind. Existing technologies have systemic deficiencies in dealing with common accidents such as vehicle skidding and tipping over, resulting in passengers, especially children and the elderly with weaker self-protection abilities, facing a higher risk of injury.

[0003] Most existing rear seats consist of only simple cushion structures or low armrests. Such designs offer only basic seating functionality and limited movement restriction, failing to provide effective active cushioning in the event of a rollover or collision. In an accident, the occupant's head, neck, and other critical areas are highly susceptible to direct impact with the ground or hard objects, lacking specialized cushioning protection, which is a major cause of serious injury. While some solutions add side panels or raise guardrails, these are essentially rigid or semi-rigid barriers, directly transmitting the impact force to the occupant's body without effectively absorbing and dissipating the impact energy. Accidents such as skidding and tipping during vehicle movement are sudden and instantaneous. From loss of balance to impact with the ground, it often happens within milliseconds. Moreover, existing protective technologies generally rely on passive contact triggering or entirely on the rider's manual reaction. The former means that "protection" is only activated when the impact has already occurred and the body is in contact with the protective structure, which means that the best buffering opportunity has already been missed. The latter is extremely unreliable due to the limited speed of human reaction. Existing technologies seriously lack the ability to monitor the dangerous posture of the vehicle in real time, make intelligent judgments, and automatically trigger the protection mechanism at the critical point of the accident, resulting in protective actions always being "half a beat too late". Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an environmentally friendly transportation safety protection device to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] An environmentally friendly transportation safety protection device includes: a safety seat body and a protective component disposed on both sides of the safety seat body. The protective component includes: two protective shells, which are respectively fixedly installed on both sides of the safety seat body; two partition plates are fixedly installed inside the protective shells; a spherical airbag is disposed between the two partition plates; a fixing plate is fixedly installed inside the protective shells; a movable hole is opened on one side of the fixing plate, which is movably sleeved with the spherical airbag; a storage hole is opened on the top surface of the protective shells; a semi-annular airbag is disposed on the top surface of the upper partition plate, which is movably sleeved with the storage hole; a shield is fixedly installed on the top surface of the protective shells; a mounting post is fixedly installed on the bottom surface of the protective shells; a detection groove is opened on one side of the mounting post, and an accelerometer is fixedly installed inside the detection groove; a support frame is fixedly installed on one side of the mounting post, and an tilt sensor is fixedly installed on the top surface of the support frame.

[0007] By adopting the above technical solution, and through the accelerometer, when a bicycle or electric vehicle tipes over, the accelerometer will first sense the signal of the vehicle suddenly accelerating and tipping over, and then trigger an alarm. At the same time, when the vehicle is tipping to one side, the tilt sensor will also sense the tilt angle of the vehicle. When the vehicle tilts to one side at an accelerated speed, it will be detected by the accelerometer. At the same time, the tilt angle will be detected by the tilt sensor. The staff can set the parameters of the accelerometer and the tilt sensor to control the activation of the semi-circular airbag and the spherical airbag. When the accelerometer and the tilt sensor simultaneously detect the set parameter signal threshold, the spherical airbag and the semi-circular airbag will be activated at the same time and inflate. At this time, the two spherical airbags will block the left and right sides of the safety seat body as a buffer, while the two semi-circular airbags will inflate upwards, reaching the neck and head of the occupant, thereby protecting the head and neck of the occupant from impact. The spherical airbags can also buffer the impact generated when the entire safety seat body falls over.

[0008] Preferably, the spring-opening assembly is disposed on one side of the protective shell. The spring-opening assembly includes: a wear-resistant plate, a plurality of flexible anti-slip blocks are fixedly installed on one side of the wear-resistant plate, a plurality of locking blocks are fixedly installed on the side of the wear-resistant plate near the fixed plate, flexible spring sheets are fixedly installed on both sides of the locking blocks, and a plurality of locking holes are opened on one side of the fixed plate, and the locking blocks are movably engaged with the locking holes.

[0009] By adopting the above technical solution, the wear-resistant plate is secured inside the locking hole by the locking block and flexible spring sheet, thus shielding the fixing plate and the spherical airbag. When the spherical airbag is activated and inflated, it will push the wear-resistant plate open, and the wear-resistant plate and the flexible anti-slip block will first contact the ground. After the spherical airbag inflates, it presses against the back of the wear-resistant plate, and the flexible anti-slip block will stick tightly to the ground, thereby increasing the friction to slow down the sliding of the vehicle and the safety seat on the ground. It also largely prevents the vehicle and the safety seat from sliding along the road surface after tilting, and the spherical airbag from being too close to the road surface and causing friction damage.

[0010] Preferably, buffer frames are fixedly installed on both sides of the safety seat body, and several energy-absorbing plates are fixedly installed inside the buffer frames. The energy-absorbing plates have a continuous Z-shaped structure.

[0011] By adopting the above technical solution, the buffer frame, when the safety seat body tilts, will also approach the ground immediately. After being squeezed, the buffer frame will squeeze the energy-absorbing plate. Since the energy-absorbing plate has a continuous Z-shaped structure, it can absorb energy and buffer, so as to cushion and protect the torso of the passenger.

[0012] Preferably, the easing assembly includes: two mounting slots, each located on one side of the car seat body; a device housing fixedly mounted inside each mounting slot; a resistance wheel on one side of the device housing; rotating columns fixedly mounted at both ends of the resistance wheel; positioning holes on both sides of the device housing; the rotating columns movably sleeved with the positioning holes; a first gear fixedly sleeved on the outer circular wall of the rotating columns; two rotating rods fixedly mounted inside the device housing; the rotating rods movably sleeved with the device housing; a second gear fixedly sleeved on the outer circular wall of the rotating rods; two take-up drums fixedly sleeved on the outer circular wall of the rotating rods; the two take-up drums are located on both sides of the second gear; the second gear meshes with the first gear; tension ropes are wound around the inner circular wall of the take-up drums; and several high-strength springs fixedly mounted on one side of the inside of the device housing, with each pair of high-strength springs forming a group; a mounting plate fixedly mounted at one end of each group of high-strength springs; and the mounting plate fixedly mounted to one end of each of the two tension ropes.

[0013] By adopting the above technical solution, the resistance wheel, when the safety seat body tilts and contacts the ground, will first contact the ground. Then, as the safety seat body slides forward, it will push the device housing and drive the resistance wheel to move. At this time, the resistance wheel will be on the ground and roll. Then, the resistance wheel will roll counterclockwise along the ground, thereby driving the rotating column and the first gear to rotate. The rotation of the first gear will mesh and drive the second gear to rotate. The rotation of the second gear will drive the winding drum to rotate around the rotating rod. During rotation, the winding drum will wind up the tension rope, which will continuously wrap around the winding drum. Inside the drum, the other end of the tension rope pulls the mounting plate closer to the drum. At the same time, the mounting plate stretches the powerful spring. Since stretching the powerful spring requires a lot of force, and since it is stretched, the force required to stretch the powerful spring needs to increase continuously. However, the potential energy of the car seat body tilting forward and sliding will continuously decrease. Therefore, through the frictional resistance between the resistance wheel and the ground, and in combination with the resistance of the powerful spring on the resistance wheel, the resistance wheel can gradually reduce its speed after rolling close to the ground, and there is a rolling buffer path when the car seat body initially falls to the ground, avoiding direct friction between the spherical airbag and the semi-circular airbag.

[0014] Preferably, a number of fixing rods are fixedly installed inside the device housing.

[0015] By adopting the above technical solution, and through the setting of fixed rods, the tension rope passes around multiple fixed rods in an S-shape inside the protective shell, which can prevent the tension rope from drooping and getting tangled.

[0016] Preferably, the device housing has movable slots on both sides, and a rotating hole is formed inside one side of each movable slot. An operating rod is movably fitted inside the rotating hole. A first torsion spring is provided on the outer circular wall of the operating rod. An operating block is fixedly installed at one end of the operating rod, and the operating block is movably fitted into the movable slot. A pawl is fixedly installed on the outer circular wall of the operating rod. Two support columns are fixedly installed inside the device housing. A third gear is movably fitted on the outer circular wall of each support column. The third gear meshes with the second gear. A movable housing is fixedly installed at one end of the third gear. A ratchet is fixedly installed at one end of the movable housing. The pawl is movably engaged with the ratchet. The movable housing and the ratchet are respectively movably fitted into the support columns.

[0017] By adopting the above technical solution, the pawl, when the second gear rotates, will engage and drive the third gear to rotate. The third gear will then drive the movable housing and ratchet to rotate counter-clockwise. When the car seat body stops sliding and the resistance wheel stops rotating, the strong spring will rebound, pulling the mounting plate and tension rope. The tension rope will then release from the surface of the winding drum and pull the winding drum to rotate. At this time, the winding drum will drive the second gear to rotate clockwise. The second gear, in turn, will engage and drive the third gear, movable housing, and ratchet to rotate counter-clockwise. The ratchet will then be locked by the pawl, thus preventing the strong spring from rebounding and causing the winding drum, second gear, first gear, and resistance wheel to rotate. When the car seat body is lifted and the strong spring is reset, rotating the operating block will drive the first torsion spring and operating lever to rotate. The operating lever will then drive the pawl to rotate, allowing the pawl to move away from the ratchet, thus facilitating the release of the one-way locking of the third and second gears.

[0018] Preferably, two limiting plates are fixedly installed inside the equipment housing, and two limiting holes are opened on one side of the limiting plates, through which the tension rope passes.

[0019] By adopting the above technical solution, the tension rope needs to pass through the inside of the limiting hole when it is wound around the inner wall of the winding drum. This makes it easier to limit the winding path of the tension rope and prevent the tension rope from moving and getting tangled with the second gear during winding, which would cause the resistance wheel to jam directly.

[0020] Preferably, fixed columns are fixedly installed on both sides of the equipment housing, a first buffer arm is movably sleeved on the outer circular wall of the fixed column, a second buffer arm is movably sleeved inside the first buffer arm, the second buffer arm is movably sleeved with the fixed column, a second torsion spring is provided on the outside of the fixed column, the two ends of the second torsion spring are fixedly installed with the first buffer arm and the second buffer arm respectively, a load-bearing column is fixedly installed inside the second buffer arm and the first buffer arm respectively, and an auxiliary wheel is movably sleeved on the outer circular wall of the load-bearing column.

[0021] By adopting the above technical solution, and with the auxiliary wheels in place, since the first and second buffer arms are arranged in a V-shape and the two auxiliary wheels are also separated in a V-shape, when the safety seat body tilts and impacts the road surface, the auxiliary wheels will transmit the impact force to the first and second buffer arms after contacting the road surface. Subsequently, the first and second buffer arms will compress the second torsion spring, and then the resistance wheel will contact the ground, thereby preventing the resistance wheel from making hard contact with the ground.

[0022] In summary, the present invention has the following main beneficial effects:

[0023] 1. This invention uses an accelerometer and a tilt sensor to detect the acceleration and tilt angle of the vehicle when it is tilted. The parameters are settable. The dual sensors work together to trigger the airbag system, achieving precise activation and timely protection. The tilting state is determined by the dual signals of acceleration and tilt angle, and the head, neck and side airbags are deployed in time to reduce the risk of injury to the occupants. The spherical airbag and the semi-circular airbag are located on both sides and the top of the seat, respectively, which can buffer the side impact, protect the head and neck, and reduce the injury from falling.

[0024] 2. This invention uses a wear-resistant plate and a flexible anti-slip block to cover the outside of the airbag. When the airbag deploys, it pushes the wear-resistant plate to touch the ground, increasing friction, slowing down the sliding, and protecting the airbag from road wear. The buffer frame and energy-absorbing plate have a Z-shaped structure, which absorbs energy through deformation, absorbs and disperses the tipping impact, and reduces the impact force on the occupant's torso when tipping over.

[0025] 3. This invention uses a resistance wheel and a winding spring mechanism to wind up the tension rope through gear transmission, stretching the strong spring to generate resistance, converting sliding kinetic energy into spring potential energy and frictional energy dissipation, gradually decelerating, avoiding direct friction between the airbag and the ground, and converting sliding kinetic energy into spring elastic potential energy through the gear and spring mechanism, effectively decelerating and prolonging the buffering process.

[0026] 4. This invention achieves unidirectional transmission and spring-loaded locking through a pawl and a ratchet, allowing the resistance wheel to transmit power in one direction to wind up the spring. After the sliding stops, the locking mechanism prevents accidental rotation.

[0027] 5. The present invention restricts the winding position of the tension rope on the winding drum by limiting the limiting hole, constrains the winding path of the tension rope, and prevents it from getting stuck due to entanglement with the gear.

[0028] 6. The present invention uses an auxiliary wheel and a buffer arm arranged in a figure-eight shape, which contact the ground before the resistance wheel and transmit the impact force to the buffer arm. The second torsion spring is compressed to absorb the initial impact energy. The impact is initially absorbed by the pre-compressed torsion spring, thus avoiding a hard landing of the resistance wheel. Attached Figure Description

[0046] 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 embodiments 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.

[0047] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An environmentally friendly transportation safety protection device includes a safety seat body 1. Protective components are provided on both sides of the safety seat body 1 for protecting personnel. Each protective component includes two protective shells 2, which are fixedly installed on both sides of the safety seat body 1. Two partition plates 3 are fixedly installed inside the protective shells 2, and a spherical airbag 5 is provided between the two partition plates 3. A fixing plate 4 is fixedly installed inside the protective shells 2, and a movable hole 6 is opened on one side of the fixing plate 4, which is movably connected to the spherical airbag 5. A storage hole 7 is opened on the top surface of the protective shells 2. A semi-annular airbag 8 is provided on the top surface of the upper partition plate 3, and the semi-annular airbag 8 is movably connected to the storage hole 7. A shielding shell 9 is fixedly installed on the top surface of the protective shells 2. A mounting post 10 is fixedly installed on the bottom surface of the protective shells 2. A detection groove 12 is opened on one side of the mounting post 10, and an accelerometer 11 is fixedly installed inside the detection groove 12. A support frame 13 is fixedly installed on one side of the mounting post 10, and an tilt sensor 14 is fixedly installed on the top surface of the support frame 13.

[0048] A spring-loaded assembly is provided on one side of the protective shell 2 to prevent the safety seat body 1 from directly rubbing against the ground after falling down. The spring-loaded assembly includes a wear-resistant plate 15. Several flexible anti-slip blocks 16 are fixedly installed on one side of the wear-resistant plate 15. Several locking blocks 17 are fixedly installed on the side of the wear-resistant plate 15 near the fixed plate 4. Flexible spring pieces 18 are fixedly installed on both sides of the locking blocks 17. Several locking holes 19 are opened on one side of the fixed plate 4. The locking blocks 17 are movably engaged with the locking holes 19.

[0049] Spherical airbag: Located between two partitions, made of high-strength wear-resistant nylon fabric, with a diameter of 20-25cm after inflation. When deployed, it can block the sides of the car seat body to form a lateral buffer barrier.

[0050] Semi-circular airbag: Located on the top surface of the upper partition, it is made of flexible and breathable nylon fabric. When inflated, its inner diameter is 15-20cm and its height is 10-15cm. After it is deployed, it extends upward to the sides of the passenger's neck and head, forming a ring-shaped protective circle.

[0051] Inflation device: Each airbag is equipped with a miniature gas generator containing compressed carbon dioxide gas, which is electrically connected to the detection and control module. After receiving a signal, it can complete inflation within 0.1-0.3 seconds.

[0052] With the built-in accelerometer 11, when a vehicle such as a bicycle or electric vehicle tipes over, the sensor can detect the signal of sudden acceleration and tipping in real time and trigger an alarm. At the same time, the tilt sensor 14 monitors the tilt angle of the vehicle. During the process of the vehicle accelerating to one side and tipping over, the accelerometer 11 detects the tilt acceleration, and the tilt sensor 14 detects the tilt angle simultaneously. The operator can control the triggering conditions of the semi-circular airbag 8 and the spherical airbag 5 by setting the parameter thresholds of both. When the two sensors reach the set threshold at the same time, the spherical airbag 5 and the semi-circular airbag 8 will inflate and deploy at the same time. The two spherical airbags 5 are located on the left and right sides of the safety seat body 1 and play a cushioning role. The two semi-circular airbags 8 inflate upwards to protect the occupant's neck and head, effectively reducing impact. The spherical airbag 5 can also cushion the impact when the seat falls to the ground. The wear-resistant plate 15 is fixed in the slot 19 by the clip 17 and the flexible spring 18, covering the outside of the fixing plate 4 and the spherical airbag 5. When the spherical airbag 5 inflates, it pushes open the wear-resistant plate 15, allowing the flexible anti-slip block 16 on its surface to contact the ground first. After the airbag inflates, it presses tightly against the back of the wear-resistant plate 15, making the anti-slip block 16 stick to the ground, increasing friction, thereby reducing the sliding distance of the vehicle and the safety seat body 1 on the ground. This design can also avoid direct friction between the airbag and the road surface, reducing the risk of damage.

[0053] Based on the above embodiments, refer to Figure 1The safety seat body 1 has a buffer frame 20 fixedly installed on both sides. The buffer frame 20 has several energy-absorbing plates 21 fixedly installed inside. The energy-absorbing plates 21 have a continuous Z-shaped structure.

[0054] With the buffer frame 20 in place, when the safety seat body 1 tilts, the buffer frame 20 will contact the ground first. After being squeezed, the buffer frame 20 will transfer the pressure to the energy-absorbing plate 21. The energy-absorbing plate 21 has a continuous Z-shaped structure. The deformation of the Z-shaped energy-absorbing plate structure consumes energy, reducing the impact force on the occupant's torso when tilting.

[0055] Based on the above embodiments, refer to Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 14 The safety seat body 1 has two easing components on its sides for slowing down the safety seat body 1. Each easing component includes two mounting slots 22, one on each side of the safety seat body 1. A device housing 23 is fixedly installed inside each mounting slot 22. A resistance wheel 24 is located on one side of the device housing 23, and rotating columns 25 are fixedly installed at both ends of the resistance wheel 24. Positioning holes 35 are located on both sides of the device housing 23, and the rotating columns 25 are movably connected to the positioning holes 35. A first gear 26 is fixedly fitted onto the outer circular wall of the rotating column 25. Two rotating rods 27 are fixedly installed inside the device housing 23. The rotating rod 27 is movably sleeved with the equipment housing 23. The outer circular wall of the rotating rod 27 is fixedly sleeved with a second gear 28. Two take-up drums 29 are fixedly sleeved on the outer circular wall of the rotating rod 27. The two take-up drums 29 are located on both sides of the second gear 28. The second gear 28 is meshed with the first gear 26. Tension ropes 30 are wound around the inner circular wall of the take-up drums 29. Several strong springs 32 are fixedly installed on one side of the inside of the equipment housing 23. Every two strong springs 32 form a group. An installation plate 33 is fixedly installed at one end of each group of strong springs 32. The installation plate 33 is fixedly installed at one end of the two tension ropes 30. Several fixing rods 34 are fixedly installed inside the equipment housing 23.

[0056] Two limiting plates 31 are fixedly installed inside the equipment housing 23. Two limiting holes 46 are opened on one side of the limiting plate 31, and the tension rope 30 passes through the inside of the limiting hole 46.

[0057] With the resistance wheel 24 in place, the resistance wheel 24 touches the ground first when the safety seat tilts down and contacts the ground. As the seat slides forward, it pushes the device housing 23 and causes the resistance wheel 24 to roll. The resistance wheel 24 rolls counterclockwise along the ground, causing the rotating column 25 and the first gear 26 to rotate. The first gear 26 meshes and drives the second gear 28 to rotate, which in turn causes the winding drum 29 to rotate around the rotating rod 27. As the winding drum 29 rotates, it winds up the tension rope 30. The other end of the tension rope pulls the mounting plate 33 to compress the strong spring 32. As the spring resistance gradually increases and the sliding potential energy of the seat gradually decreases, combined with the ground friction of the resistance wheel 24, a deceleration effect is achieved. This mechanism allows the seat to slow down its sliding through a rolling buffer path during the initial falling stage, avoiding direct friction between the airbag and the ground.

[0058] Based on the above embodiments, refer to Figure 1 , Figure 6 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 The equipment housing 23 has movable slots 36 on both sides. A rotating hole 37 is opened on one side of the movable slot 36. An operating rod 40 is movably sleeved inside the rotating hole 37. A first torsion spring 38 is provided on the outer circular wall of the operating rod 40. An operating block 39 is fixedly installed at one end of the operating rod 40. The operating block 39 is movably sleeved with the movable slot 36. A pawl 45 is fixedly installed on the outer circular wall of the operating rod 40. Two support columns 44 are fixedly installed inside the equipment housing 23. A third gear 41 is movably sleeved on the outer circular wall of the support column 44. The third gear 41 meshes with the second gear 28. A movable housing 42 is fixedly installed at one end of the third gear 41. A ratchet 43 is fixedly installed at one end of the movable housing 42. The pawl 45 is movably engaged with the ratchet 43. The movable housing 42 and the ratchet 43 are movably sleeved with the support column 44 respectively.

[0059] When the second gear 28 rotates, the pawl 45 engages and drives the third gear 41, the movable housing 42, and the ratchet 43 to rotate counterclockwise. After the seat stops sliding, the strong spring 32 rebounds and pulls the tension rope 30, causing the winding drum 29 to rotate in the opposite direction. At this time, the ratchet 43 is locked by the pawl 45, achieving one-way locking and preventing the mechanism from reversing due to the rebound of the strong spring 32. After lifting the safety seat body 1, the pawl 45 can be disengaged from the ratchet 43 by rotating the operating block 39 to unlock it, ensuring system stability after deceleration and facilitating reset operation.

[0060] Based on the above embodiments, refer to Figure 1 , Figure 6 and Figure 16Fixed columns 47 are fixedly installed on both sides of the equipment housing 23. A first buffer arm 48 is movably sleeved on the outer circular wall of the fixed column 47. A second buffer arm 49 is movably sleeved inside the first buffer arm 48. The second buffer arm 49 is movably sleeved with the fixed column 47. A second torsion spring 52 is provided on the outside of the fixed column 47. The two ends of the second torsion spring 52 are fixedly installed with the first buffer arm 48 and the second buffer arm 49 respectively. A load-bearing column 50 is fixedly installed inside the second buffer arm 49 and the first buffer arm 48 respectively. An auxiliary wheel 51 is movably sleeved on the outer circular wall of the load-bearing column 50.

[0061] With the auxiliary wheel 51, the first buffer arm 48 and the second buffer arm 49 are arranged in a V-shape, and the two auxiliary wheels 51 are also extended outward in a V-shape. When the seat tilts and impacts the ground, the auxiliary wheel 51 contacts the ground first, transmits the impact force to the buffer arm and compresses the second torsion spring 52, and then the resistance wheel 24 contacts the ground, avoiding rigid collision between the resistance wheel 24 and the ground. The impact is initially absorbed by the pre-compressed torsion spring, avoiding hard landing of the resistance wheel.

[0062] Working principle: Please refer to Figures 1-16 As shown, when a bicycle or electric vehicle tipps over, the accelerometer 11 first senses the signal of the vehicle suddenly accelerating and tipping over, and then triggers an alarm. At the same time, when the vehicle is tipping to one side, the tilt sensor 14 also senses the tilt angle of the vehicle. When the vehicle tilts to one side at an accelerated speed, it will be detected by the accelerometer 11. At the same time, the tilt angle will be detected by the tilt sensor 14. The operator can set the parameters of the accelerometer 11 and the tilt sensor 14 to control the activation of the semi-annular airbag 8 and the spherical airbag 5. When the accelerometer 11 and the tilt sensor 14 simultaneously detect the set parameter signal threshold, the spherical airbag 5 and the semi-annular airbag 8 will be activated at the same time and inflate. At this time, the two spherical airbags 5 will block the left and right sides of the safety seat body 1 as a buffer, while the two semi-annular airbags 8 will inflate upwards and reach the neck and head of the passenger, thereby protecting the head and neck of the passenger from impact. The spherical airbags 5 can buffer the impact generated when the safety seat body 1 falls over.

[0063] The wear-resistant plate 15 is secured inside the locking hole 19 by the locking block 17 and the flexible spring 18, thus shielding the fixing plate 4 and the spherical airbag 5. When the spherical airbag 5 is activated and inflated, it will push the wear-resistant plate 15 open, and the wear-resistant plate 15 and the flexible anti-slip block 16 will first come into contact with the ground. After the spherical airbag 5 inflates, it presses against the back of the wear-resistant plate 15, and the flexible anti-slip block 16 will stick tightly to the ground, thereby increasing the friction to slow down the sliding of the vehicle and the safety seat body 1 on the ground. It also largely prevents the vehicle and the safety seat body 1 from sliding along the road surface after tilting, and the spherical airbag 5 from being too close to the road surface and causing friction damage.

[0064] With the buffer frame 20 in place, when the safety seat body 1 tilts, the buffer frame 20 will also approach the ground immediately. After being squeezed, the buffer frame 20 will squeeze the energy-absorbing plate 21. Since the energy-absorbing plate 21 has a continuous Z-shaped structure, it can absorb energy and buffer, so as to cushion and protect the torso of the passenger.

[0065] When the safety seat body 1 tilts and contacts the ground, the resistance wheel 24 will be the first to contact the ground. As the safety seat body 1 slides forward, it will push the device housing 23 and move the resistance wheel 24. At this time, the resistance wheel 24 will be on the ground and roll. Then, the resistance wheel 24 will roll counterclockwise along the ground, causing the rotating column 25 and the first gear 26 to rotate. The rotation of the first gear 26 will mesh with and drive the second gear 28 to rotate. The rotation of the second gear 28 will drive the take-up drum 29 to rotate around the rotating rod 27. During rotation, the take-up drum 29 will wind up the tension rope 30, which will continuously wrap around the take-up drum. Inside 29, the other end of the tension rope 30 will pull the mounting plate 33 closer to the winding drum 29. At the same time, the mounting plate 33 will stretch the strong spring 32. Since stretching the strong spring 32 requires a lot of force, and since it is stretched, the force of stretching the strong spring 32 needs to be continuously increased. However, the potential energy of the safety seat body 1 tilting forward will be continuously weakened. Therefore, through the frictional resistance between the resistance wheel 24 and the ground, and in conjunction with the resistance of the strong spring 32 on the resistance wheel 24, the resistance wheel 24 can be made to gradually reduce its speed after rolling on the ground, and there is a rolling buffer path when the safety seat body 1 initially falls to the ground, avoiding direct friction between the spherical airbag 5 and the semi-circular airbag 8.

[0066] The pawl 45, when the second gear 28 rotates, engages and drives the third gear 41 to rotate. The third gear 41 then drives the movable housing 42 and ratchet 43 to rotate counter-clockwise. When the car seat body 1 stops sliding, the resistance wheel 24 stops rotating, and the strong spring 32 rebounds. The strong spring 32 then pulls the mounting plate 33 and the tension rope 30 to move. The tension rope 30 then releases from the surface of the winding drum 29, pulling the winding drum 29 to rotate. At this time, the winding drum 29 drives the second gear 28 to rotate clockwise, and the second gear 28 engages the... When the third gear 41, movable housing 42, and ratchet 43 rotate counterclockwise, the ratchet 43 will be locked by the pawl 45, thus preventing the strong spring 32 from rebounding and causing the winding drum 29, second gear 28, first gear 26, and resistance wheel 24 to rotate. When the safety seat body 1 is lifted up and the strong spring 32 is reset, the first torsion spring 38 and operating lever 40 will be rotated by rotating the operating block 39. In turn, the operating lever 40 will drive the pawl 45 to rotate, allowing the pawl 45 to move away from the ratchet 43, thus facilitating the release of the one-way locking of the third gear 41 and the second gear 28.

[0067] With the auxiliary wheel 51 in place, and the first buffer arm 48 and the second buffer arm 49 arranged in a V-shape, and the two auxiliary wheels 51 also separated in a V-shape, when the safety seat body 1 tilts and impacts the road surface, the auxiliary wheel 51 will transmit the impact force to the first buffer arm 48 and the second buffer arm 49 after contacting the road surface. Then the first buffer arm 48 and the second buffer arm 49 will compress the second torsion spring 52, and then the resistance wheel 24 will contact the ground, thereby preventing the resistance wheel 24 from making hard contact with the ground.
