A movable connecting portion and an opening-and-closing portion provided on the support portion enable users to put on the device quickly when travelling. When the protection device is connected to a vehicle frame, no additional weight is imposed on the rider's body, while the safety of the rider is protected. A balance device for maintaining balance is provided between the protection device and the vehicle, and when the protection device is movably connected to a shock-absorbing seat, injury to the internal organs of the human body caused by the vehicle during a collision can be prevented.

Description

A collision-resistant body protection device Technical Field

[0001] This invention relates to the field of personal safety protective equipment, specifically an anti-collision device worn by the human body during travel, and more specifically, an anti-collision human protective device. Background Technology

[0002] Currently, when people travel by motorcycle, electric bike, or bicycle, they mostly choose to equip the vehicle with a simple sunshade, rainproof canopy, and windproof / heatproof blanket (made of soft fabric) supported by a vertical frame. This provides no strong protection for the vital organs, which are highly vulnerable to injury and could be life-threatening. Furthermore, the head is often only covered by a simple, existing plastic headgear with very limited protection. In the event of a collision, the body's impact with the road or other vehicles can easily damage vital organs. Additionally, after a car stops, drivers or passengers often fail to check behind the vehicle, and when they forcefully push open the door, the door frequently collidees with oncoming electric bikes. Or motorcycles, causing electric bikes or motorcycles to lose balance, often result in oncoming cars or other electric bikes or motorcycles hitting or running over the fallen rider in the instant they fall, causing serious damage to the rider's vital organs and endangering their life (we have seen and heard of too many of these tragic scenes, which is truly heartbreaking and regrettable). Also, when people are sleeping in a vehicle, their heads are tilted to one side for a long time, which can cause chronic damage to the cervical spine. Especially in a high-speed vehicle, if passengers are resting or sleeping while the vehicle is in a violent collision, the person's head and neck are easily seriously injured when they are violently thrown around without any warning.

The movable connecting parts and opening and closing parts on the support section make it easy for people to put on the device quickly when traveling. When the protective device is connected to the frame, it does not add any weight to the rider's body, maximizes the protection of the rider's life, and is also easy to store. The support unit features a soft or elastic lining. When the body is impacted from the outside, the soft or elastic lining can reduce the impact force on the upper body and head during the shock. The balancing device connecting the body protection to the frame allows the rider's body to sway left and right or back and forth with the vehicle during riding, maintaining the balance between the vehicle and the rider and preventing injury from falling over due to loss of balance. Safety warning markings that reflect light when illuminated by other vehicles' headlights are placed on the outer surface of the body protection or on the outer cover of the body protection. This provides a more intuitive warning to other vehicles on the road when riding at night, and also adds an extra layer of safety when riding at night.

Detailed Implementation

[0157]

Example 1

[0158] As shown in Figures 1, 11, and 23, a collision-resistant body protection device includes a support part A1 (a support frame that withstands external pressure). The support part A1 is made of a raw material with hardness (such as high-strength metal or carbon fiber) or material. The support part A1 supports an internal space that can accommodate a human body (the support part A1 and the support part A1 are connected together to form an internal space that can accommodate a human body) or is connected by a support part connector A3 between the support parts A (1) to form a body protection device that can accommodate a human body (the two ends of the support part connector A (3) are connected to the corresponding upper and lower support parts A (1)). Now, taking the upper, middle, and lower three (three-layer) support parts A1 as an example (the support parts A (1) are arranged horizontally and are also placed in layers), the support part A1 is an arc shape corresponding to the shape of the human body or a ring shape corresponding to the shape of the human body (an angle shape can also be set on the support part A1 for connection needs). To reduce the weight of the support A1 while maximizing its supporting force, the support A1 is preferably designed as an arc-shaped tubular structure. Multiple support connectors A3 connect the upper and lower support A1 sections (multiple vertically arranged support connectors A3 are provided on the front, back, left, and right sides of the upper and lower support A1 sections, and these vertically arranged support connectors A3 are connected to the horizontally arranged upper and lower support A1 sections as a whole; that is, a fixed connection, such as welding, is made at the adjacent or contacting parts of the corresponding support A1 and the corresponding support connector A3). To reduce the weight of the protective device while maintaining its overall impact resistance and protective strength, the support A1 sections are preferably hollowed out. Movable connecting parts 15 (hinged structure) connect the two sides of the rear support A1 to the opposite sides, allowing them to be connected as a whole and rotate relative to each other. The shaft holes C25 on both sides of the connecting part 15 are respectively connected to the corresponding support parts A1 (the shaft holes C25 are staggered on the outer surface of the support parts A1 on both sides) or respectively connected to the corresponding support part connectors A(3) on both sides. A load-bearing member 4 is provided in the shaft holes C25 on both sides of the support part A1 to connect them together. On the left and right sides of the front support part A1, there are opening and closing parts 16 that can connect the support parts A1 on both sides into one or separate them into two parts. (For locking or snap-fit ​​structures), the triplock A33 on one side of the opening / closing part 16 is connected to one side of the corresponding support part A1. The bracket 36, spring A37, movable triplock A34, and pull cable 38 on the other side of the opening / closing part 16 are connected to the corresponding support part A1 on the other side. Alternatively, the opening / closing part 16 can be connected to the corresponding support part connectors A3 on both sides (the left and right ends of the support part A1 with the opening / closing part 16 are respectively connected to the corresponding support part connectors A3 on both sides).Specifically, the two ends of the bracket 36 are fixedly connected to the corresponding sides inside the support part A1. The movable tripod A34 is horizontally arranged on the upper part of the bracket 36 (at the center position). At the center position of the movable tripod A34, a short shaft 35 is fixedly connected downwards. The short shaft 35 passes downwards through the corresponding shaft hole provided on the bracket 36 (the diameter of the shaft hole provided on the bracket 36 is slightly larger than the diameter of the short shaft 35). The downward exposed end of the short shaft 35 is connected to a screw to prevent the short shaft 35 from moving upwards. The cap M242 is connected. A spring A37 is provided on one side of the movable trip A34. One end of the spring A37 is connected to one side of the movable trip A34, and the other end of the spring A37 is connected to the corresponding support A1 (the inner surface of the support A1 is connected). One end of the pull wire 38 is connected to the movable trip A34 on the side opposite to the spring A37. The other end of the pull wire 38 passes through the pull wire outer sleeve 39 and then extends outward from the corresponding support A1 (a hole is opened on the surface of the support A1 to accommodate one end of the pull wire 38 extending outward). The small hole required for the pull cable extends outward and connects to the upper part of the movable handle A67 located at the front of the support A1. The outer surfaces of the front and rear ends of the pull cable sleeve 39 are fixedly connected to the support A1 (the inner surface of the support A1) in contact with it. The lower end of the handle bracket A66 is fixedly connected to the lower corresponding support A1 (connected to the front support A1). The upper end of the handle bracket A66 is movably connected to the movable handle 67. (An inner...) is fixedly connected to the upper end of the handle bracket A66. The upper part of the load-bearing component 4 is connected to the movable connecting part 15. After the upper and lower parts of the load-bearing component 4 are connected, a screw cap with a diameter larger than the shaft hole C25 is fitted on the upper and lower parts of the load-bearing component 4. The inner surface of the screw cap is fixedly connected to the load-bearing component 4 that is in contact with the inside. The screw cap is used to prevent the support part A1 from falling off the load-bearing component 4. The lower part of the load-bearing component 4 is connected to the corresponding frame on the motorcycle, electric vehicle or tricycle. When starting to ride, first grasp the lower part of the movable handlebar A67. As the lower part of the handlebar A67 retracts inward, the upper part of the handlebar A67 swings outward around the through hole on the handlebar bracket A66, simultaneously pulling the pull cable 38 connected to it. The pull cable 38 pulls the movable tripod A34 connected to it, causing the two sides of the movable tripod 34 to move away from the lower parts of the two triplocks 33 (the lower parts of the triplocks 33 with protruding parts). Simultaneously, the springs connected to the movable tripod 34... Spring A37 is stretched, at which point the front parts of support A1 separate (opening outwards respectively). When the rider's upper body enters a space supported by support A1 that can accommodate the upper body, the rider then uses both hands to rotate the two sides of support A1 inwards. When the two sides of support A1 close relative to each other, the triplock A33 (the inclined part at the top of triplock A33) on one side of support A1 pushes the movable triplock A34 to move. When triplock A33 extends into the rear of movable triplock A34,As the spring A37 retracts, it pulls the movable tripod A34 to engage with the lower part of the tripod lock A33 (below the protruding part). At this time, the two support parts A1 are connected as a single unit. Thus, the multiple support part connectors A3 connecting the support parts A1 are connected to form a hard outer shell (cover). When the vehicle is unfortunately hit by another vehicle or falls and is run over by the wheels of other small vehicles, the vital organs of the human body can be protected from injury by the hard outer shell (cover) of the support part A1. This provides an extra layer of safety for people riding bicycles when wearing helmets with neck protection or existing ordinary helmets. Additionally, safety warning markings (markers can be stripes or various patterns) are placed on the outer surface of the protective device or on the outer cover (a cover that can shield from wind and rain or provide some cushioning in the event of a collision). These markings reflect light when illuminated by the headlights of other vehicles. This provides a more intuitive warning to other vehicles on the road when riding at night, and also adds an extra layer of safety when riding at night. Alternatively, multiple corresponding support parts A1 can be arranged vertically and then connected together to form a protective device with a central space to accommodate the human body, consisting of multiple support parts A1 connected together. This involves replacing the support connector A3 and support net 79 connecting the support parts A1 with multiple corresponding support parts A1 arranged vertically (multiple horizontally arranged support parts A1 are stacked vertically to a certain required height, and then fixedly connected, such as welded, between each support part A1 to the contacting support parts A1 to form a protective device that can accommodate the upper body). Alternatively, the multiple horizontally arranged support parts A1 can be replaced with an arc-shaped plate structure corresponding to the human body shape, with the required height and hardness, and multiple holes can be made in this plate to reduce weight and allow ventilation.

[0159]

Example 2

[0160] As shown in Figure 1, a layer of support mesh 79, made of a rigid material such as steel or carbon fiber, is provided around a collision-resistant personal protective device (with open spaces between support parts A1 and between support parts A3) formed by connecting support parts A1 and support parts connector A3. This support mesh 79 consists of several regular or irregular small holes (connected by connectors). One side of the support mesh 79 is fixedly connected to the upper part of the corresponding support part A1 and support parts connector A3, and the lower part is fixedly connected to the lower part of the corresponding support part A1 and support parts connector A3. The other side of the support mesh 79 is fixedly connected to the upper part of the corresponding support part A1 and support parts connector A3, and the lower part is fixedly connected to the lower part of the corresponding support part A1 and support parts connector A3. When the protective device collides with a protruding or sharp impact object (support part A1...). The rigid support net 79, with its gap between the support part A1 and the support part A1, provides ventilation and reduces the weight of the protective device while also protecting the internal organs from protruding or sharp objects. If double or multiple layers of support net 79 are added to the protective device, and the gaps (small holes) on the support net 79 are staggered (when the connectors between several mesh holes on the second layer of support net 79 are set as circular or conical structures, and then respectively set in the middle position of the corresponding mesh holes at the rear of the first layer of support net 79), it can effectively defend against the injury of sharp objects larger than the mesh holes, including bullets fired from small handguns. (When a sharp object or bullet hits the circular or conical support net connector, the tip of the sharp object or bullet will slide on the surface of the circular or conical mesh connector, the center of gravity will shift, and the penetrating power of its front end will be weakened. This can effectively prevent the sharp object or bullet from causing injury to the human body after piercing the protective device.)

[0161]

Example 3

[0162] As shown in Figures 3 and 23, an upper limb channel 14, made of a support connector A3, is provided on the left and right sides of the upper part of the support A1. This channel allows both upper limbs to pass through (the internal space of the upper limb channel Q169 can be appropriately increased to accommodate most people). The upper and lower sides of the upper limb channels 14 on the left and right sides are connected to the corresponding support A1 or support connector A3. Two neck braces capable of bearing a certain weight are provided on the support A1 (above the shoulders) of the upper limb channel 14. These neck braces include neck supports B85 or neck straps. The front and rear ends of the two neck supports B85 are connected to the corresponding support A1 or to the corresponding support connector A3. (Alternatively, a support connector A3 can be provided at the lower part of the front and rear ends of the neck supports B85, with its upper and lower ends connected to the corresponding upper and lower support A1.) The ends are respectively connected to the corresponding support connectors A3. On the front and rear sides of the support A1 at the upper part of the upper limb channel 14, there are movable connecting parts 15 (at the rear of the support A1) and opening and closing parts 16 (at the front of the support A1) with the same structure as those on the support A1 at the lower part of the upper limb channel 14. The load-bearing member 4 extends upward and connects to the movable connecting part 15 at the upper part of the upper limb channel 14 (after the load-bearing member 4 extends upward into the shaft holes C25 on the left and right sides of the support A1, it connects the shaft holes C25 on the left and right sides of the movable connecting part 15 together). On the left and right sides of the support A1 at the upper front of the upper limb channel 14, there are corresponding opening and closing parts 16 connected to the left and right sides of the left and right sides of the support A1 at the lower front of the upper limb channel 14 in the same way as the opening and closing parts 16 on the support A1 at the lower front of the upper limb channel 14). On one side of the opening and closing part 16, there is a pull line 38 for pulling the movable trip A34 to move and connected to the upper part of the corresponding movable handle A67 at the lower part.When the rider wears it, by pinching the lower part of the movable handlebar A67 and retracting it inward, the upper part of the movable handlebar A67 (with the shaft hole on the upper part of the handlebar bracket A66 as the lever fulcrum) pulls the pull cable 38 connected to it to swing outward. At the same time, the pull cable 38 pulls the movable tripod A34 connected to it to move outward (the left and right sides of the movable tripod A34 move away from the lower parts of the left and right tripods A33 respectively). At this time, the support parts A1 on the upper and lower sides of the upper limb channel 14, under the action of the movable connecting part 15 (the load-bearing part 4 connects the shaft holes C25 provided on the support parts A1 on both sides), move from the opening... After the clasp 16 separates, it opens to the left and right sides respectively. Then, similar to putting on a shirt, both upper limbs pass through the upper limb channels 14 on the left and right sides respectively. Then, use your hands to rotate the left and right support parts A1 together inward, engaging with the opening and closing parts 16 connected to the left and right sides of the support part A1 respectively (the movable tripod A34 on one side of the opening and closing part 16 is in a locked state when it moves to the lower part of the tripod lock A33 under the pull of the spring A37). This connects the left and right sides of the support part A1 into one unit. At this time, the weight of the entire support part A1 falls on the two neck braces B85 provided on the upper part of the human shoulder. The protective device (support part A1) of the B85 is not limited to being fixedly connected to the frame. Workers in other hazardous industries, such as counter-terrorism and riot control, can also wear this protective device while wearing their helmet, significantly reducing the risk to their lives. If the support part A1 is made of a strong yet lightweight material, such as carbon fiber, plastic, or lightweight metal, it could also be used by the elderly when walking in snowy weather, allowing them to wear this lightweight protective device while wearing their helmet. This would prevent injuries from slippery surfaces and falls. Using lightweight materials to manufacture the support part A1... In the case of a protective device, in order to reduce weight while maintaining structural strength, the protective device can be made into a single unit (without movable connecting parts 15 and opening / closing parts 16 on the support part A1). When wearing it, raise both hands above the head and pass them through the space inside the support part A1 from bottom to top. Then, the hands extend out from the left and right upper limb channels 14 on the upper part of the support part A1, and the head extends upward from the middle of the left and right neck braces B85. The left and right neck braces B85 fall on the upper part of the left and right shoulders respectively. Alternatively, the left and right neck braces B85 can be replaced with two neck straps.

[0163]

Example 4

[0164] As shown in Figures 1 and 4, based on Figure 1, a head and neck protection device is constructed by connecting a support part B2, a support part connector B83, and a neck brace A77 or neck strap. Specifically, a head and neck protection device (support part B2) that can swing back and forth is movably connected to the upper part of the anti-collision protective device (support part A1). A movable connecting part 15, consisting of a connecting shaft K82 and a shaft hole A18, is provided at the lower part of the support part B2. The specific connection structure is as shown in Figure 4, located below the support parts B2 on both the left and right sides. A shaft hole A18 is fitted onto a connecting shaft K82 that is laterally connected to the part. The lower part (outer surface of the lower part) of the shaft hole A18 is integrally connected to the upper part of the load-bearing component 4. A strip-shaped (or line-shaped) neck brace A77 capable of bearing a certain weight is set on the left and right sides of the support part B2. The front and rear ends of the two neck braces A77 are fixedly connected to the corresponding support parts B2. Two support part connectors B83 (or two support parts B2) are laterally provided on the front of the support part B2.

[0165] The left and right ends of the upper and lower support connectors B83 are fixedly connected to the left and right sides of the corresponding support B2. An observation hole 17 in the shape of a long arc is provided between the upper and lower support connectors B83. A transparent cover (transparent plastic or tempered glass) is installed in front of the observation hole 17. An opening / closing part 16 is provided at the lower front of support B2 and the upper front of support A1, respectively, consisting of two movable trip connection holes H24, two movable trips H21, a spring H22, and two trip locks H20. The outer surfaces of the two movable connection holes H24 are connected to the lower front of the corresponding support B2 (the outer surface of support B2). A collar integrally connected to the movable trip H21 is fitted onto the outer ring of the two movable trip connection holes H24 (the outer ring of the movable trip connection hole H24 is movably connected within the collar on the upper part of the movable trip H21). The two opposite movable trips... A spring H22 that can rebound is horizontally connected between the tripwires H21. The left and right ends of the spring H22 are respectively connected to the left and right sides of the two corresponding movable tripwires H21. Two tripwires H20 with holes (similar to screw caps or rings, each with a space in the center) are provided on the support part A1 corresponding to the lower part of the movable tripwires H21. After aligning the centers of the holes of the two tripwires H20, the lower parts of the left and right tripwires H20 are respectively fixedly connected to the corresponding support part A1. The space between the support part B2 and the support part connector B83 and the space between the support part B2 and the neck brace A77 (between the upper part of the neck brace A77 and the corresponding support part B2) (excluding the observation hole 17) can be connected by a support net 79, or it can be wrapped and connected by connectors made of hard plastic or metal plates of corresponding shapes. The support net 79 provided on the protective device can also be replaced by connectors made of hard plastic or metal plates of corresponding shapes for wrapping and connection according to different needs.When cycling, squeeze the movable handlebar A67 to separate the left and right sides of the opening / closing part 16. After the upper body enters the protective device, push the support part A1 inward with both hands to bring the left and right sides of the opening / closing part 16 together (the connection structure and opening / closing operation method are the same as in Embodiment 1 and Figure 1). Then, use two fingers of one hand to pinch the two movable tripwires H21 on the head protection device and the spring H22 connecting the two movable tripwires H21 inward together, and pull them down to the middle of the two triplocks H20 on the support part A1 at the upper front of the protective device. Then release the two fingers. At this time, the spring H22 will rebound and push the two movable tripwires H21 outward, so that the protruding parts on the two movable tripwires H21 will extend into the corresponding left and right triplocks H20. At this time, the head protection device and the protective device are connected as one unit, and the neck guards A77 on the left and right sides of the head protection device fall down onto the human body. The upper part of the left and right shoulders is designed for easy wearing, eliminating the need for the upper limbs to pass through the left and right upper limb channels 14 separately. After the body protection device and head protection device are integrated, there is also space between the upper part of the left and right neck guards A77 and the corresponding support part A1 at the bottom to accommodate the swinging of the upper limbs. Importantly, when the upper part of the head protection device is hit by an external impact, the impact force on the head protection device is transmitted to the load-bearing component 4 connected to the frame. If the vehicle and the rider fall to the ground together after a collision, the body will have an inertia that propels it forward. At this time, the gravity generated by the body's forward movement is transmitted through the left and right shoulders to the left and right neck guards A77 respectively (the weight that the two shoulders can bear is much greater than the weight that the human cervical spine can bear). In this way, the top of the person's head will not collide violently with the top of the head protection device (the inner surface of the head protection device) inside the head protection device. This can effectively protect the rider's head and neck from injury, and at the same time, people's safety when riding a bicycle is guaranteed. If the two upper and lower support connectors B83 horizontally provided at the front of the support part B2 are replaced with the corresponding two support parts B2, the left and right ends of the upper and lower support parts B2 are respectively fixedly connected to the left and right sides of the corresponding support parts B2 as a whole.

[0166]

Example 5

[0167] As shown in Figures 2, 3, 4, and 23, an additional support section A1 is installed on the upper part of the protective device. On the front and rear sides of this support section A1, there are movable connecting parts 15 (connected to the left and right sides of the rear part of the support section A1) and opening / closing parts 16 (connected to the left and right sides of the front part of the support section A1), and pull cords 38, all identical to those on the protective device. One end of the pull cord 38 is connected to a movable trip A34 on the opening / closing part 16, and the other end of the pull cord 38 extends downwards along the support section A1 to the upper part of the corresponding movable handle A67, connecting to the upper part of the movable handle A67. This design is consistent with the lower support section of the support section A1. Between the support parts A1, there is an upper limb channel 14 connected around the perimeter by a support part connector A3. The center is hollow, allowing both upper limbs to pass through smoothly. The outer periphery of the two upper limb channels 14 is connected to the corresponding support part A1 or support part connector A3. A neck brace B85 is set on the left and right sides of the support part A1 (above the left and right shoulders). The front and rear ends of the two neck braces B85 are fixedly connected to the front and rear sides of the corresponding support part A1. The load-bearing member 4 extends upward and passes through the shaft holes C25 connected on both sides of the support part A1 (as shown in Figure 23, at the movable connection part 15). The shaft holes C25 provided on the upper part are respectively connected to the left and right sides of the rear part of the support A1, which are relatively separated. The support A1 is connected together vertically. The load-bearing component 4 is then connected upward to the shaft hole A18 provided on the upper part of the connecting shaft K82. The left and right ends of the connecting shaft K82 are respectively connected to the left and right sides of the corresponding support B2 (head protection device). There is also a movable trip connection hole H24 on the left and right sides of the lower front part of the support B2. The outer surfaces of the two movable trip connection holes H24 are respectively connected to the lower front part of the corresponding support B2 (outer surface of the support B2). The upper part of the two movable trip holes H21 is respectively provided with A collar integrated with the movable trip H21 is fitted onto the outer ring of the connecting hole H24 of the left and right movable trips respectively. A spring H22 is horizontally connected between the two opposite movable trips H21. The left and right ends of the spring H22 are connected to the left and right sides of the corresponding left and right movable trips H21 respectively. Two trip locks H20 with holes (similar to screw caps or rings, each with a space in the center) are provided on the support part A1 corresponding to the lower part of the two movable trips H21. After aligning the centers of the holes of the two trip locks H20 left and right, the lower part (lower surface) of the two trip locks H20 is connected to the corresponding support part A1 respectively.This embodiment is based on Figure 3, with a head protection device (without a neck guard B85) movably connected (the two left and right neck guards A77 on the head protection device shown in Figure 4 are removed and connected to the upper part of Figure 3). The left and right shoulders respectively bear the weight of the body protection device and the head protection device. This structure is not limited to connection with the vehicle frame; it can be worn according to different industry needs. It allows for free movement and can also be fixedly connected to the body protection device and the head protection device as a whole as needed (the body protection device and the head protection device do not have the opening and closing part 16, the movable connection part 15, the pull cable 38, the handle bracket A67, and the fixed handle). The bracket A66 secures the left and right sides of the protective device together after they align, and then connects the lower part of the head protection device downwards to the upper part of the corresponding lower protective device. When working in dangerous industries (such as counter-terrorism, explosion protection, or work environments with falling objects from heights), the head and upper body are enclosed within the head protection and body protection devices, preventing the important and vulnerable cervical spine from being exposed and from bearing additional weight (the head protection device transmits the external force to the left and right shoulders of the body through the neck brace B85). This can prevent serious injury to the cervical spine that could lead to death.

Example 6

[0169] As shown in Figures 5, 11, and 15, the protective device (support part A1) and the head protection device (support part B2) are connected vertically as a whole (support part A1 is connected to support part B2, or support part connector A3 is connected to support part B2, or support part A1 is connected to support part connector B83, or support part connector A3 is connected to support part connector B83). Then, it is divided into front and rear parts. At the left and right sides of support part A1 or support part connector A3 connected to support part A1, at opposite front and rear (front and rear opposite) ends, there is an opening / closing part 16 with the same structure as in Embodiment 1. For example, as shown in Figure 11 (the structure provided on both sides of the opening / closing part 16), brackets 36 are connected to both sides of the front support part A1 (brackets). Both ends of 36 are fixedly connected to the inner surface of the corresponding support A1. The movable tripod A34 is movably connected to the upper part of the corresponding bracket 36 (a short shaft 35 is fixedly connected downward at the center position of the movable tripod A34, and after the short shaft passes downward through the corresponding shaft hole provided on the bracket 36, the exposed end of the short shaft 35 is connected to the nut M242 to prevent the short shaft 35 from falling outward). One end of the spring A37 is connected to the inner surface of the corresponding support A1, and the other end of the spring A37 is connected to one side of the corresponding movable tripod A34. The other side of the movable tripod A34 is connected to one end of the pull wire 38. The other end of the pull wire 38 passes through the corresponding pull wire outer sleeve 39 and is connected to the lower part of the opening and closing switch 238. The front part (support part A1) of the protective device has a set of opening and closing parts 16 as described above (shown in Figure 11) on both sides. One end of the fixed bracket 88 passes through the corresponding shaft hole in the middle (vertically centered position) of the opening and closing switch 238. The left and right ends of the fixed bracket 88 are then connected to the corresponding sides of the support part A1. The outer surfaces of the left and right pull cable sleeves 39 are fixedly connected to the support parts A1 they are in contact with. On the left and right sides of the rear support part A1, there are triplocks A33 corresponding to the two movable triplocks A34 on the left and right sides of the front part (the triplocks A33 on the left and right sides are fixedly connected to the ports of the corresponding support parts A1). On the front and rear sides of the protective device (support part A1), the upper... The lower parts of the front and rear sides of the corresponding head protection device (support part B2) are integrally connected. A movable connecting part 15 is provided on the upper part of the head protection device (support part B2) to connect the two sides of the head protection device together and allow the two sides of the head protection device to swing relative to each other, as shown in Figure 15 (the movable connecting part 15 has structures on both sides). The shaft holes H27 provided on the movable connecting part 15 are respectively connected to the left and right sides of the upper part of the head protection device (support part B2) (the centers of the shaft holes H27 are aligned left and right and then connected to the front and rear opposite ends of the support part B2 on the left and right sides), or connected to the corresponding support part connectors B83 on both sides (a support part connector B83 is provided on each of the left and right sides of the connecting shaft C26).The left and right ends of the two support connectors B83 are connected to the corresponding left and right support parts B2 respectively. Then, the shaft holes H27 on both sides of the movable connecting part 15 are respectively set on the corresponding support connectors B83. After the connecting shaft C26 passes through the shaft holes H27 respectively provided on the corresponding left and right support parts B2, the front and rear parts of support part A1 and support part B2 are connected together (the front and rear parts of support part A1 and support part B2 can swing relative to each other as a movable connection). The lower part of the load-bearing component 4 is connected to the corresponding lower balance device or directly to the frame. The upper part of the load-bearing component 4 is connected upwards to the upper part. The middle part (center of left and right) of one side (rear side) of the corresponding protective device (support part A1) is connected as one piece. On the left and right sides of the head protection device (support part B2), there is a spring that can remain stationary when the protective device and the head protection device swing upward to a certain angle (about 90 degrees) on one side (front or rear side) without the action of external force. One end of the two springs is connected to the left and right sides of the front part of the head protection device (support part B2) respectively, and the other end of the two springs is connected to the left and right sides of the corresponding head protection device (support part B2) or the protective device (support part A1) at the rear respectively. When riding a bicycle, first use one hand to press the upper part of the opening / closing switch 238 located at the front of the protective device (support part A1). At this time, the lower part of the opening / closing switch 238 uses the fixed bracket 88 as a fulcrum, which pries the pull cables 38 connected to its left and right sides to extend forward. At the same time, the other ends of the two pull cables 38 pull the movable tripwires A34 (movable tripwires A34 located on one side of the opening / closing part 16) on the left and right sides connected to them respectively, and they move together. At this time, the two movable tripwires A34 separate from the lower part of the tripwires A33 (tripwires A33 located on one side of the opening / closing part 16) that are engaged with them (separate from the lower part of the protruding parts on the tripwires A). At this time, the opening / closing part 16 is in the unlocked state. Then, use your hand to pull one side (front side) of the protective device and headgear upwards to extend it forward and upward to a certain angle (close to 90° or slightly greater than 90°) to facilitate the rider getting on and off the bicycle. For the purpose of this, the springs connected to both sides of the head protection device (support part B2) (on the left and right sides of the movable connecting part 15 provided on the upper part of the head protection device) will pull the head protection device (support part) to the side that is raised, so that it maintains a certain raised state without external force (hand pulling force). When the person sits on the seat, both upper limbs extend forward from the upper limb channels 14 provided on the left and right sides of the body protection device (support part A1) to the raised side of the body protection device (support part A1), and then press the corresponding body protection device (support part A1) from top to bottom or from outside to inside with their hands, so that it swings backward to match the corresponding body protection device (support part A1) at the rear. (When the movable trip A34 provided on the front side of the body protection device contacts the inclined angle of the trip lock A33 provided on the rear side of the body protection device, the movable trip A34 will slide down on the trip lock A33 to the lower part of the trip lock A33.)When the spring A37 connected to the movable tripod A34 pulls the movable tripod A34 to the lower part of the tripod lock A33 with a protrusion, the opening and closing part 16 is in the locked state. When the front and rear sides of the protective device (support part A1) and the head protection device (support part B2) are connected as a whole, one side (rear side) of the protective device (support part A1) and the head protection device (support part B2) is connected to the corresponding lower balance device or frame, and the opposite side (front side) can move up and down (raise or lower) as needed. Under the action of the opening and closing parts 16 provided on their front and rear sides respectively, and the pull cable 38 and opening and closing switch 238 provided on the front of the protective device (support part A1), they are locked together as a whole when the vehicle is moving. When the vehicle is stopped, they can be divided into front and rear parts by the action of the movable connecting part 15 provided on the head protection device (support part B2). The internal organs of the human body are protected by the sturdy protective device. Inside the device (support part A1), the head and neck are protected by a sturdy head protection device (support part B2), thus maximizing the protection of the most vulnerable internal organs and the head and neck. In the event of a collision or fall, and unfortunately being run over or impacted by other vehicles, such as similar vehicles or small cars, the sturdy body and head protection devices can support and resist the crushing or impact of external forces. This provides a certain level of safety for people riding bicycles. Consequently, people can choose electric bicycles or electric motorcycles for short-distance travel, which can reduce the inconvenience caused by urban traffic congestion and make travel greener, more environmentally friendly, and more economical. While being convenient and quick to wear (because existing helmets are inconvenient to wear and store and have limited protective capabilities, so most people do not wear helmets when traveling), it also reduces the valuable time and energy spent by traffic police on requiring us to wear helmets when riding bicycles. The load-bearing component 4 can also be replaced from the lower rear part of the protective device (support A1) to the lower front part of the protective device (support A1). The upper part of the load-bearing component 4 is fixedly connected to the middle (left-right center) of the lower front part of the protective device, and the lower part of the load-bearing component 4 is connected downward to the corresponding balance device or frame. When the position of the load-bearing component 4 is changed, the rear side of the protective device (support A1) and the head guard device (support B2) can be opened when people get on and off the vehicle (the front side is connected to the frame, and the rear side can be opened and closed up and down). This also makes it easier for riders to get on and off the vehicle and can also play the same protective role. Alternatively, the protective device (support A) and the headgear can be divided into left and right parts. Specifically, the movable connecting part 15 is moved downwards from the upper part of the headgear (support B2) to one side (right or left) of the protective device (support A1) or the headgear (support B2). The shaft holes H27 on both sides of the movable connecting part 15 are respectively connected to the front and rear opposite sides of the support A1 or the support B2 (two front and rear opposite cross-sections of the support A1 or the support B2). The shaft holes H27 on both sides are also connected together by the connecting shaft C26.The lower part of one side (left or right) of the protective device (support part A1) is also connected to the upper part of the load-bearing component 4. The other side of the protective device (support part A1) and the headgear (support part B2) can open and close left and right under the action of the movable connecting part 15, making it convenient for the rider to wear it from one side (getting on the bike from the left or right).

[0170]

Example 7

[0171] Figures 16 and 17 show several hinge structures with slightly different structures but essentially the same function, which can connect the two support parts and allow one or both support parts to swing left and right or up and down individually or together. Figure 16 also shows a structure in which the shaft hole and the connecting shaft cooperate to rotate. Specifically, on the support parts A1 on the left and right sides, two (at least one or more) shaft holes B28 arranged vertically are connected (the center of the shaft hole B28 is through). Then, a connecting shaft A29 corresponding to the shaft hole B28 is set up. One end of the two connecting shafts A29 passes through the corresponding upper and lower shaft holes B28 from top to bottom or from bottom to top. Then, a connector B30 is set horizontally in the middle position (the vertical center position) of the two connecting shafts A29. The left and right ends of the connector B30 are connected to the corresponding left and right connecting shafts A29 respectively. The horizontally set connector B30 is then connected to the corresponding vertically set load-bearing component 4 (connected to the load-bearing component 4 at the left and right center position of the connector B30). For example, Figure 17 shows a connection structure in which the shaft hole and the connecting shaft rotate in cooperation. Specifically, two (at least one) angled connecting shafts B32 are respectively provided on the support parts A1 on the left and right sides (two connecting shafts B32 arranged vertically at right angles upward or downward on one side of the support part A1) and two (at least one) corresponding shaft holes D31 are respectively connected on the support part A1 on the other side. One end of the two connecting shafts B32 is connected to the corresponding support part A1 on the other side, and the other end of the connecting shaft B32 (the angled end) extends upward into the two shaft holes D31 connected on the other side of the support part A1.

[0172] [Example 8]

[0173] As shown in Figures 5, 25, and 26, a neck brace, including a neck support frame, is horizontally installed on the left and right sides of the protective device (support A1) or head protection device (support B2) to withstand a certain weight. Figure 26 shows the structural diagram of the neck brace, which includes a telescopic component 143 and a kit 144. Two rings C145 are integrally connected to the front left and right sides of the telescopic component 143. A support frame is installed within the two opposing rings C145. The corresponding connecting shaft Q146 passes through the two left and right collars C145. The exposed left and right ends (the forward-protruding parts) of the connecting shaft Q146 then connect to the inner surfaces of the corresponding front support parts B2. The rear of the telescopic member 143 extends into a closed assembly 144 with a diameter slightly larger than its outer circumference. Two collars C145 are also integrally connected to the rear of the assembly 144. A connecting rod is also provided within the two opposing collars C145. The corresponding connecting shaft Q146 passes through the left and right collars C145. The exposed left and right ends (the rearward-protruding parts) of the connecting shaft Q146 then connect to the inner surface of the corresponding rear support part B2. When one side of the support part A1 and support part B2 rises upwards under the action of the movable connecting part 15 on the support part B2 for easy wearing by the rider, the telescopic member 143, under the action of the front collar C145 and the connecting shaft Q146 within the collar C145, moves along with the support part A1. 1. While moving upward together with the support part B2, the rear part of the telescopic component 143 extends upward from inside the kit 144. At this time, the kit 144 also changes its angle upward with the telescopic component 143 under the action of the ring C145 connected to it and the connecting shaft Q146 provided in the ring C145. When the overall angle of the neck brace B147 is tilted upward, it is not only convenient for the rider to wear it when getting on the bike, but also less likely to hit the head. In the event of a collision, it can also play an important role in protecting the rider's head and neck.

[0174]

Example 9

[0175] As shown in Figures 5 and 25, the retractable neck braces on the left and right sides of the head protection device (support B2) or body protection device (support A1) are replaced with retractable neck straps (including a pull bar, a pull strap, and a pull cord). When the neck strap is a pull bar, it slowly extends outward from the roller when pulled lightly. When pulled forcefully, a locking structure engages the rotating gear that moves with the pull bar with a gear that restricts its rotation, as shown in Figure 25. A spring piece 148 is provided on the corresponding support A1 or support B2. One end of the spring piece 148 is connected to the inner surface of the corresponding rear support A1 or support B2, and the other end of the spring piece 148 passes forward and through the roller 154. The roller 154 is integrally connected to the center of the rotating gear 151 via a connecting shaft W150 (one end of the connecting shaft W150 is fixedly connected). The other end of the connecting shaft W150 extends outward from the center of the roller 154 (the connecting shaft W150 and the roller 154 are rotatably connected). One side of the roller 154 is integrally connected to one side of the corresponding rotating gear 151 (the rotating gear 151 has a shaft hole at its center that allows the corresponding connecting shaft W150 to pass through smoothly). The other side of the roller 154 is connected to one end of a helical spring 152. The other end of the helical spring 152 wraps around the outer circumference of the corresponding roller 154 several times and then connects to the inner surface of the corresponding fixed wheel 231. One side of the outer surface of the fixed wheel 231 is in contact with a support. The outer surface of part A1 or support part B2 is connected (or a spring piece 148 can be provided between the fixed wheel 231 and the corresponding support part A1 or support part B2 at the rear, with one end of the spring piece 148 fixedly connected to one side of the outer surface of the corresponding fixed wheel 231, and the other end of the spring piece 148 fixedly connected to the outer surface of the corresponding support part A1 or support part B2 at the rear). The upper part of the rotating gear 151 is provided with a gear catch 149 that engages with the grooves on its outer circumference when the rotating gear 151 moves upward to a certain height. The side of the gear catch 149 with grooves faces downward and corresponds to the grooves on the rotating gear 151. The side of the gear catch 149 without grooves (the rear end of the gear catch 149) is connected to the rear. The surface of the corresponding support part A1 or support part B2 is fixedly connected. After one end of the pull bar 153 is fixedly connected to the outer surface of the roller 154, the other end of the pull bar 153 is wrapped around the outer circumference of the roller 154 several times and then fixedly connected to the corresponding support part A1 or support part B2 at the front (front side) (extending from the upper part of the shoulder from back to front). When the front part (front side) of the protective device (support part A1) and the head protection device (support part B2) which are integrally connected with the pull bar 153 are gently pulled upwards, the front part (front end) of the pull bar 153 changes angle forward and upward, and at the same time, it pulls the pull bar 153 wrapped on the rear roller 154 to extend forward. At the same time, the roller 154 drives the rotating gear 151 integrally connected with it to rotate together.When the shoulder moves rapidly upward, it exerts a strong upward and forward force on the upper tension bar 153. At this time, as the tension bar 153 pulls the roller 154, the rotating gear 151 integrally connected to the roller 154, and the connecting shaft W150 connected to one end of the spring piece 148, the force on the connecting shaft W150 exceeds the spring piece's own bearing capacity. The spring piece 148 then swings forward and upward along with the connecting shaft W150 and the rotating gear 151. During this upward swing, the rotating gear 151 engages with the gear catch 149 on its upper part (the textured surface of the rotating gear 151 meshes with the textured surface of the gear catch 149), causing the rotating gear 151 and the roller 154 integrally connected to it to stop rotating. The neck brace structure described above is identically configured on both sides (the upper part of the left and right shoulders) of the corresponding support part A1 or support part B2.

[0176]

Example 10

[0177] As shown in Figures 5, 6, and 7, a balancing device between the rider and the vehicle is constructed by connecting the protective device (support A1) to the lower frame. This device allows the rider to swing back and forth or side to side with the body, and also lowers the center of gravity of the protective device when the vehicle is parked (as the protective device increases the vehicle's height when vertically connected to the frame). This prevents the vehicle from easily slipping on uneven surfaces or in windy weather, thus reducing the risk of damage to the rider or surrounding people or property. For example, a swing element A5 (which can be a retractable spring, elastic strip, elastic sheet, liquid bladder, or air bladder) is installed between the protective device (support A1) and the lower frame. The upper part of the swing element A5 connects to the corresponding support A1 or the support... A1 is connected to the support connector A3 or the load-bearing component 4 connected to the support A1. The lower part of the swing component A5 is connected to the corresponding lower adjustment component 6 or to the frame connector 12 or to the corresponding lower frame, as shown in Figures 5 and 7 (balancing device). The upper part of the load-bearing component 4 is connected to the support A1, and the lower part of the load-bearing component 4 is connected to the upper part of the swing component A5. The lower part of the swing component A5 is connected to the upper part of the corresponding lower adjustment component 6. The lower part of the adjustment component 6 extends downward into the retractable component 243 (which is closed at the outside and bottom, open at the top, and a hollow tubular structure in the middle) that allows the adjustment component 6 to adjust the height of the protective device according to the needs of the human body. A certain length is provided on one side of the top opening of the retractable component 243. A vertical notch 99, approximately 3 cm in diameter and 2 cm in width, is provided around the retractable part 243 (around the vertical notch 99). A clamping element, as shown in Figure 6, is located on the periphery of the retractable part 243. The clamping element includes two arc-shaped clamping plates 239. On each side of the two arc-shaped clamping plates 239, there is a corresponding screw hole 232 or shaft hole. A corresponding screw rod 233 is inserted into one of the two corresponding screw holes or shaft holes on one side of the two arc-shaped clamping plates 239. A nut 234, corresponding to the rotating thread on the screw rod 233, is fitted onto one end of the screw rod 233. A pulling rod 237 is inserted into one of the two corresponding screw holes 232 or shaft holes on the other side of the two arc-shaped clamping plates 239. One end of the pulling rod 237 (exposed) is... One end of the swing handle 235 is provided with a handle connection hole 236. One end of the swing handle 235 is movably connected to the handle connection hole 236 (the hook on the swing handle 235 is hooked on the outer ring of the handle connection hole 236). By rotating the nut 234 and pulling one end of the swing handle 235 with the protrusion inward, the hook on the other end of the swing handle 235 hooks the outer circumference of the handle connection hole 236 and rotates inward. At the same time, the protrusion on the swing handle 235 pushes the arc-shaped clamp 239 in contact with it inward and retracts inward until the outer side of the protrusion on the swing handle 235 (the side closest to the handle) fits against the outer surface of the corresponding arc-shaped clamp 239. This structure allows the two arc-shaped clamps 239 to tighten quickly.Alternatively, the pull rod 237 and the swing handle 235 can be replaced with the same setup of a screw rod 233 connected to one side of the arc-shaped clamp 239 and a corresponding nut 234. The same screw rod 233 is used, passing through the two screw holes 232 on the other side of the arc-shaped clamp 239 (the side where the swing handle 235 was originally located). A corresponding nut 234 is then fitted onto the exposed end of the screw rod 233. This structure allows the two arc-shaped clamps 239 to face each other by rotating the nut 234. The contraction tightens inward (moves inward), while the contraction member 243 (vertical notch 99) between the two arc-shaped clamps 239 contracts inward, making the contraction member 243 and the internal adjustment member 6 tightly integrated. The outer surface of one side (front or rear) of the lower part of the contraction member 243 is fixedly connected to an outwardly protruding swing stop 11 and then extends downward into a positioning tube 7 with a diameter slightly larger than it, an open upper part, and a closed lower and outer perimeter. On the left and right sides inside the positioning tube 7 (on the left and right sides of the swing stop 11) On the inner surface, a relatively protruding limiting clip 10 is fixedly connected to each of the following: a limiting clip 11 that prevents 360° rotation; a rotating sleeve 13 (which is through to the left and right) is connected to the lower part (outer surface of the bottom) of the positioning tube 7; a connecting shaft (which is also the lower part of the frame connector 12) corresponding to the rotating sleeve 13 is inserted inside the rotating sleeve 13; the left and right ends of the connecting shaft are respectively connected to the upper corresponding frame connector 12; a bracket that can be connected to the upper end of the left and right positioning springs 8 is fixedly connected laterally on the left and right sides of the outer surface of the positioning tube 7; the lower ends of the left and right positioning springs 8 are respectively connected downward to the lower part of the lower corresponding frame connector 12 or to the lower corresponding frame; a backward-recessed limiting groove (a limiting groove to restrict the positioning tube 7 from swinging backward or left and right) is provided at the center left and right position on the upper part of the frame connector 12; the frame connector 12 is then connected to the lower corresponding vehicle as a whole (the lower part of the frame connector 12 is connected to the frame on the vehicle). When a person wearing the protective gear is riding a bicycle, and their upper body needs to sway left and right or back and forth with the vehicle, the swinging component A5 connected to the lower part of the protective gear will bend and deform with the body to maintain the balance between the person and the vehicle. When parking the bicycle, the protective gear (support part A1) can be pulled forward and downward. Under the action of the two positioning springs 8 on the left and right, the protective gear will slowly fall down. In this way, the protective gear (support part A1) lowers the center of gravity without violently impacting the front of the vehicle and causing damage to the front parts of the vehicle. To adjust the height of the protective gear (support part A1) on the frame according to the person's height, first loosen the clamping part 9 (the nut on one side) or one side of the swing handle 235, then move the protective gear and the adjusting part 6 connected to it upward or downward by hand. After the adjusting part 6 is moved to the desired position, tighten the clamping part 9 by hand (turn the nut on one side or pull the swing handle 235 inward) so that the tightening part 243 is tightened (connected) to the adjusting part 6.

[0178]

Example 11

[0179] Figures 10 and 12 show several adjustment structures for adjusting the height of the protective device using the adjusting component 6. For example, as shown in Figure 10, the adjusting component 6 uses a screw rod and a corresponding nut to adjust the height of the protective device. Specifically, the lower part of the protective device or the lower part of the load-bearing component 4, which is integrally connected to the protective device, is connected to the upper end of a screw rod K217 with a rotating thread. The lower end of the screw rod K217 extends downward into a nut K218 integrally connected to the upper part of the torsion frame 101 (the torsion frame 101 is connected around its perimeter, and a nut K218 corresponding to the screw rod K217 and capable of rotating in conjunction with the rotating thread on the screw rod K217 is fixedly connected at opposite upper and lower positions). A screw rod K217 is also provided at the lower part of the torsion frame 101. The upper end of the screw rod K217 extends upward into the corresponding screw cap K218 at the lower part of the torsion frame 101. The lower end of the screw rod K217 is connected downward to the corresponding swing member A5, positioning tube 7, or frame. When adjusting the height of the protective device, the torsion frame 101 can be rotated by hand. At this time, the two screw caps K218, which are integrally connected to the torsion frame 101, will move up and down on the corresponding screw rod K217 (one screw cap K218 moves upward on the corresponding screw rod K217, and the other screw cap K218 moves downward on the corresponding screw rod) to change the length of the screw rods K217 exposed at both ends of the torsion frame 101 (so that the screw rods K217 exposed at both ends become longer or shorter at the same time) to achieve the purpose of adjusting the height of the protective device.Another method involves providing transverse shaft holes on one side of the adjusting component 6 and the retracting component 243, and then connecting them with a short shaft corresponding to their shaft holes to adjust the height of the protective device on the frame. For example, as shown in Figure 12, a shaft hole N244 is provided transversely at the lower part of the adjusting component 6, which is closed on one side and open on the opposite side. A retractable spring G107 with a corresponding diameter smaller than that of the shaft hole N244 is first installed in the shaft hole N244, with one end of the spring G107 extending inward into the shaft hole N244. The inner surface corresponding to the shaft hole N244 is connected. The other end of the spring G107 is connected outward to a short shaft C108 extending into the shaft hole N244 and its interior (the diameter of the short shaft C108 is smaller than the diameter of the spring G107 and the shaft hole N244). The other end of the short shaft C108 extends outside the shaft hole N244 (the end of the short shaft C108 protruding outside the shaft hole N244 is semi-circular). On one side of the contraction member 243, there are multiple shaft holes G106 arranged vertically, corresponding to the short shaft C108 (shaft holes G106). (The diameter of the shaft is slightly larger than the diameter of the short shaft C108). When adjusting the height of the protective device on the frame, one hand holds the protective device and pulls it upwards, while the fingers of the other hand press inwards on the exposed outer surface of the short shaft C108 on one side of the retractable part 243. At this time, the short shaft C108 retracts inwards under the action of the spring G107, simultaneously pulling the protective device and the adjusting part 6, which is integrally connected to the protective device. The adjusting part 6 drives the short shaft C108, which moves together with it, to move upwards. At the same time, the adjusting part 6 moves upwards within the retractable part 243 to the required height, and then... After the retractable member 243 has a corresponding shaft hole G106 on one side (the exposed end of the short shaft C108 on the adjusting member 6 is opposite to the shaft hole G106 of the retractable member 243 at a corresponding height), the short shaft C108 is pushed outward by the spring G107, so that the exposed end of the short shaft C108 extends outward and passes through the corresponding shaft hole G106 on the retractable member 243. The shaft hole G106 then restricts the vertical movement range of the short shaft C108, thereby achieving the purpose of adjusting the height of the protective device on the frame. Alternatively, the shaft holes on the adjusting member 6 and the retractable member 243 can be connected front-to-back or left-to-right, and then a movable shaft (with a diameter slightly smaller than the shaft hole and a length slightly longer than the diameter of the retractable member 243) corresponding to their respective shaft holes can be used to connect them front-to-back or left-to-right.

Example 12

[0181] Figures 8, 9, 13, and 14 show several examples of protective devices (support A1) connected to a swinging component. This allows the protective device (support A1) to swing back, forth, left, and right as needed to maintain vehicle balance. For example, the swinging component shown in Figure 13 consists of a lower, arc-shaped torsion member 102 located at the bottom of the protective device or load-bearing component 4. The upper part of the torsion member 102 is integrated with the lower part of the protective device or load-bearing component 4. At the bottom of the torsion member 102, there is an upright, retractable base spring 103 with a diameter smaller than the torsion member 102. The upper part of the base spring 103 abuts against the bottom of the torsion member 102 (movable connection). The lower part of the base spring 103 is connected to the corresponding lower frame. A pull rope 104 or rod of corresponding length is located at the center of the base spring 103. One end of the pull rope 104 is connected to the bottom of the torsion member 102. The other end of 04 is pulled down to twist the member 102, causing the base spring 103 to contract slightly. The other end is then connected to the lower part of the corresponding base spring 104 or the corresponding frame. If a pull rod is used instead of the pull rope 104, the upper end of the pull rod is movably connected to the bottom of the corresponding twist member 102 (the upper end of the pull rod is provided with a shaft hole, and a vertically erected collar is also provided at the bottom of the twist member 102, which is fitted in the shaft hole. The upper surface of the collar is connected to the bottom of the corresponding upper twist member 102). When the protective device needs to swing back and forth or left and right, the bottom of the twist member 102, which is connected to the protective device, slides on the upper part of the base spring 103 (on the annular opening at the upper end of the base spring 103) under the action of the pull rope 104. At the same time, according to the change in the amplitude of the sliding, the base spring 103 is also pressed to contract downward or rebound upward. Alternatively, as shown in Figure 14, the swinging component can be fitted with a large washer 105 (which can be made of metal or hard plastic) between the bottom of the torsion member 102 and the upper part of the base spring 103. The washer 105 has a through hole in the center for the up-and-down movement of the pull rope or pull rod. The diameter of the washer 105 is larger than the diameter of the upper part of the base spring 103. In this way, the upper end of the pull rope 104 or pull rod passes through the corresponding through hole in the washer 105 and then connects to the bottom of the corresponding torsion member 102. When the bottom of the torsion member 102 swings, the process of friction and compression with the upper surface of the washer 105 will become smoother. Another type is the rocking component shown in Figure 8, which has a through hole 266 on the upper part of the frame connector 12 (at the center of the left and right sides of the frame connector 12) with a diameter larger than that of the load-bearing component 4. A spring F73 (or an elastic band) is provided on the left and right sides of the lower part of the frame connector 12. The lower end of the load-bearing component 4, which is connected to the protective device, passes down through the through hole 266 and is then connected to one end of the corresponding left and right springs F73. The other ends of the left and right springs F73 are connected to the left and right sides of the corresponding frame connector 12.Another type is the swing component shown in Figure 9, where the protective device or load-bearing component 4 is connected to the center of the upper part (upper surface) of the swing frame 74 (integrated with the swing frame 74). Two springs L76 are provided on the left and right sides of the lower part of the swing frame 74, one in front and one behind. The upper end of each spring L76 is connected to the corresponding upper part of the swing frame 74, and the lower end of each spring L76 is connected to the corresponding lower part of the spring connecting frame 75. The lower part of the spring connecting frame 75 is connected to the corresponding frame. The springs L76 mentioned above can also be fully enclosed gas bags or liquid bags (containing gas or liquid) made of a stretchable or elastic material (such as rubber) on the outside. When the load-bearing component 4 swings, the pressure generated on one side acts on the gas bag or liquid bag on one side, and the gas bag or liquid bag (volume) will be squeezed and expanded. When the load-bearing component 4 is in an upright state, the gas bag or liquid bag also returns to its original state.

Example 13

[0183] Figures 20, 21, 22, 18, and 19 show several opening and closing parts 16 (also locking structures) that can separate the two sides of the support into two parts or lock them into a whole, but with slightly different structures but basically the same function. They are provided with a triplock (fixed triplock) and a movable triplock on opposite sides of the support. By combining or separating the triplock and the movable triplock, the two sides of the support can be connected into a whole (locked together) or separated into two parts. A locking structure 16 is provided in which a tapered triplock with multiple serrated edges on one side of the support A1 is inserted into a movable triplock with a corresponding shape and multiple serrated edges on its inner surface on the opposite side of the support A1. Locking is achieved by the interlocking of the serrated edges on the triplock and the movable triplock. Specifically, as shown in Figure 20, a tapered triplock B52 (the diameter of triplock B52 is smaller than the diameter of the corresponding movable triplock B47) is provided at the end of one side of the support A1. Several (two or more) serrations are provided on the outer surface of triplock B52. One end of 2 extends into the port of the corresponding support part A1, and then the corresponding support part A1 and the corresponding triplock B52 are connected as one unit by multiple connectors B53 (the two ends of the connectors B53 are fixedly connected to the inner surface of the corresponding support part A1 and the outer surface of the corresponding triplock B52 respectively). In the port of the opposite support part A1, there is a movable triplock B47 with a top-wide and bottom-narrow inner surface corresponding to the triplock B52, which also has several (two or more) corresponding concave and convex teeth. (It is a movable triplock B47 composed of two corresponding top-wide and bottom-narrow semi-circular shapes that can be fastened to the outer surface of the corresponding triplock B52.) The movable tripod (B47) has a shaft hole P140 (annular ring) on ​​each of its left and right sides, which is fitted onto the corresponding connector C51. The shaft hole P140 (annular ring) has a certain range of swing or movement when it surrounds the connector C51, and there is a certain amount of space between the shaft hole P140 (annular ring) and the connector C51. Both ends of the connector C51 are connected to the surface of the corresponding inner ring 141 and the surface of the corresponding support A1, respectively. The two shaft holes P140 (annular rings) are located on the left and right sides. Each of the two movable trips B47 is connected to one end of the corresponding movable trips B47 (the outer surfaces of the two shaft holes P140 (rings) are connected to one end of the corresponding movable trips B47 on the left and right sides (the middle part of the wider end). The other ends of the movable trips B47 (the narrower end) are connected to both ends of the springs C49 (one end of the spring C49 is connected to the inner surface of the corresponding movable trip B47 on one side, and the other end of the spring C49 is connected to the inner surface of the corresponding movable trip B47 on the other side). A movable collar 50 is fitted around the outer periphery of the movable trips B47.A spring B48 is installed on each side of the upper part of the movable collar 50. One end of each spring B48 is connected to the corresponding connector C51, and the other end of each spring B48 is connected to the corresponding movable collar 50. A pull member 142 is installed on each side of the lower part of the movable collar 50. One end of each pull member 142 is connected to the corresponding side of the movable collar 50, and the other end of each pull member 142 extends inward to a certain required length before the two ends are connected together. The lower part of the pull member 142 is connected to the pull line 38 (one end of the pull line 38) extending outward from the pull line outer tube 39. When the pull line 38 is pulled, the pull line 38 drives the movable collar 50, which is integrally connected with the pull member 142, and the springs B48 on both sides of it to move inward. When the spring C49 at one end of the movable stop B47 extends laterally, the space inside the movable stop B47 increases. As the spring C49 extends laterally, it pushes the lower parts of the movable tripods B47 on both sides to expand to the corresponding sides. At this time, the triplock B52 is inserted into the space inside the movable tripod B47. When the pull line 38 is released (when the pull line 38 is released, the two springs B48 exert pressure on the outer circumference of the movable tripods B47 on both sides, forcing the spring C49 between the movable tripods B47 to retract and narrow the internal space), the spring B48 pulls the movable collar 50 connected to it to move outward (from the part with a smaller diameter to the part with a larger diameter). At this time, the space inside the movable tripod B47 becomes smaller (the spring C49 retracts), and the serrations on the triplock B52 engage with the serrations on the movable tripod B47 (the protruding part on one side sinks into the groove on the other side). At this time, it is in the locked state. The principle and operation steps for unlocking and locking are the same. Pulling the pull cord 38 moves the collar 50 inward, causing the spring C49 connecting the movable tripwires B47 on both sides to extend relatively, increasing the space at the bottom. At this time, the corresponding triplock B52 can extend into or out of the space between the movable tripwires B47 on both sides. Exiting is unlocking, and extending is locking. (Pulling the pull cord 38 increases the space between the movable tripwires B47 on both sides, making it easier for the triplock B52 to move in and out of the space. Releasing the pull cord 38 reduces the space between the movable tripwires B47 on both sides. If the triplock B52 is in the space, it is in the locked state; if the triplock B52 is not in the space, it is in the unlocked state.)

[0184] Another type of opening and closing part 16 (locking structure) uses the elastic force of a spring to engage the triplock and the movable triplock together. For example, as shown in Figure 21, a slightly curved or angled triplock X109 and a conical insertion end 216 are connected to the end of the support part A1 on one side (the diameter of the insertion end 216 is smaller than the inner diameter of the support part A1 on the opposite side). At the end of the support part A1 on the opposite side, a movable triplock X110 is provided, consisting of a bracket X114 of a certain height, a spring X113, and a swing member B118. The lower ends of the left and right sides of the bracket X114 are respectively connected to the outer surface of the corresponding support part A1, and the upper ends of the left and right sides of the bracket X114 are connected to the outer surface of the corresponding support part A1. Each end of the swing member B118 has a shaft hole M112 (the centers of the two shaft holes M112 are opposite each other). The front part of the swing member B118 is set in the shaft hole M112 (it is rotatably connected in the shaft hole M112, and the left and right sides of the swing member B118 are integrally connected to the front and rear parts of the swing member B118). On each side of the swing member B118, there is a long through groove 117 that is closed on all sides and hollow in the center, which is required for the left and right sides of the spring connecting shaft 116 to move back and forth. A spring connecting shaft 116 corresponding to the through groove 117 is set in the through groove 117. The spring connecting shaft 116 is connected to one end of the spring X113 at the center position. The other end is connected to a spring connector 115 on the bracket X114 corresponding to the front part (the left and right ends of the spring connector 115 are respectively connected to the left and right sides of the corresponding bracket X114). On the exposed left and right sides of the spring connecting shaft 116, a shaft hole X111 is fitted to the front and left and right sides of the movable trip X110 as an integral connection (rotatable connection in the shaft hole X111). When the left and right support parts A1 need to be connected as one, first insert the insertion end 216 into the port of the corresponding support part A1, and then pinch the rear part of the swing member B118 and push it upward (swing upward). At this time, the swing member B118 drives the movable trip X110, which moves as one with it, to move together. The movable tripod X110 moves forward to the rear of the triplock X109 on the opposite side of the support A1, and then pulls (presses) the swing member B118 downward, so that the swing member B118 is pressed against the outer surface of the corresponding support A1 (the height of the bracket X114 and the spring connector 115 makes the swing member B118 form a certain angle when it moves downward to the outer surface of the corresponding support A1, and it is pressed against the outer surface of the support A1 under the action of the spring X113). At this time, the front of the movable tripod pulls the triplock X109 (the front of the movable tripod X110 is sleeved on the rear of the triplock X109) to the corresponding side, so that the two support A1s are connected as one.Another type of opening / closing part 16 (locking structure) achieves the connection or separation of the two support parts A1 by pressing the unlocking part to cause the movable trip to swing up and down or left and right under the action of the spring. For example, as shown in Figure 22, a triplock T119 with a closed perimeter and a space left in the center is fixedly connected to the inner side of one end of the support part A1. On the opposite support part A1, a movable triplock T120 is provided, which has an upward protrusion at the front and a shaft hole T125 on each of the left and right sides of the rear (the centers of the two shaft holes T125 are opposite each other). The protrusion of the movable triplock T120 faces upward. A corresponding movable triplock connecting shaft T124 passes through the two shaft holes T125 at the rear and then extends inward into the inner side of the corresponding support part A1. The left and right ends of the movable triplock connecting shaft T124 are respectively connected to the two sides of the corresponding support part A1. A spring T121 is provided at the lower part of the movable triplock T120. One end of the spring T121 The spring T121 is fixedly connected to the inner surface of the corresponding support A1. The other end of the spring T121 is connected to the lower surface of the corresponding upper movable stop T120. A locking member T123 is provided on the upper part of the movable stop T120. The lower end of the locking member T123 extends downward from the through hole T122 provided on the corresponding support A1 to the upper surface of the corresponding movable stop T120 (abutting against the upper surface). The other end of the locking member T123 protrudes from the outside of the corresponding support A1. When downward... When one end of the unlocking component T123 is pressed, the other end of the unlocking component T123 will press down on the movable trip T120 and move it downwards. At the same time, the spring T121 retracts, and the front part of the movable trip T120 extends into the trip lock T119. When the unlocking component T123 is released, the spring T121 will push the movable trip T120 upwards while rebounding. At this time, the protrusion at the front of the movable trip T120 will be locked into the upper part of the trip lock T119, and the lock is engaged.Another type of opening / closing part 16 achieves the purpose of connecting or separating the two support parts by swinging the movable latches on both sides of the locking member to connect or separate the latches. As shown in Figure 18, two opposing latches W126 are respectively provided on the inner side of the port of the support part A1 on one side (the two ends of the two latches W126 are respectively fixedly connected to the inner surface of the corresponding support part A1). On the opposite side of the support part A1, a movable latch W127 corresponding to the two latches W126 is also provided. A short shaft extending downwards is connected to the rear part of each of the two movable latches W127. Two short shafts are each fitted with a corresponding shaft hole W129. One side of each of the two shaft holes W129 (rings) is integrally connected to a movable trip connector W130 (connected to one side of the movable trip connector W130) located at the lower part of the two movable trips W127. The two ends of the movable trip connector W130 are connected to the inner surface of the corresponding support A1. Between the two movable trips W127 at the rear, there is a swing member C132 whose length is slightly longer than the distance between the two movable trips W127. A vertical shaft W134 (vertical shaft) is connected to each end of the swing member C132. The height of shaft W134 is less than the height of the inner diameter of the corresponding support A1. A locking element B133, protruding from the support A1 and with a handle at its upper end, is provided on the upper part of the swing member C132. The lower end of the locking element B133 passes downward through the through hole V131 on the corresponding support A1 and then connects downward to the lower corresponding swing member C132. A spring W128 is provided between the two movable trippers W127. The two ends of the spring W128 are respectively connected to the inner side of the corresponding movable tripper W127. When the locking element B133 is twisted, it drives the swing member C132 and the swing member C132. When the two vertical shafts W134 connected by 132 swing together, the swinging component C132 (when the two sides of the swinging component C132 are close to a straight line) pushes the left and right sides of the rear of the movable trip W127 to move outward respectively. At this time, under the action of the shaft hole W129 provided on the movable trip connector W130 and the short shaft provided in the shaft hole W129, the two movable trips W127 and the spring W128 at the front of the movable trip W127 retract inward respectively. At this time, the protrusions provided on the front of the two movable trips W127 separate from the two trip locks W126 respectively, which is the unlocked state.Another type of opening and closing part 16 (locking structure) is achieved by connecting a knob to the left and right sides of the support part A1 or the support part connector A3 respectively, so that the corresponding concave and convex threads on the two knobs are combined (inlaid) or separated, so that the left and right sides of the support part A1 are connected as one piece or divided into two parts. Taking the concave and convex threads on the knobs as an example, as shown in Figure 19, a large fixing ring 139 is set at the two ports of the left and right sides of the support part A1 respectively to prevent the knob A135 and knob B136 from falling outward (the inner surfaces of the two large fixing rings 139 are fixedly connected to the outer surfaces of the corresponding support parts A1 by multiple connectors L199). A rotatable knob A135 and a knob B136 with a diameter slightly smaller than that of knob A135 are respectively set on the outer periphery of the two large fixing rings 139. The inner surface of the knob A135 is provided with concave and convex threads (which is also the internal structure of the nut). The outer surface of knob B136 is also provided with corresponding convex and concave threads that can be rotated (which are also the external structure of the screw rod). At the rear of knobs A135 and B136, there are small collars A137 and B138 respectively, whose outer circumference (outer surface) is connected to their rear by multiple connectors. The inner surfaces of small collars A137 and B138 rub against the outer surface of the support A1 fitted inside them. When the support A1 on the left and right sides needs to be connected as one, the knob B136 with external thread 240 is twisted by hand and inserted into the knob A135 with internal thread 241. The two knobs are then rotated in opposite directions to connect them as one under the action of the threads. Alternatively, one of knobs A135 or knob B136 can be connected to the corresponding support A1 as one (fixed) and the other knob can be rotated to achieve the purpose of connecting as one. Another common locking structure of the opening and closing part 16 in existing door locks is to rotate a gear so that the gear drives the movable tripping block that meshes with it, which extends into one side of the tripping lock to achieve the purpose of locking or engaging. Alternatively, it can be achieved by pulling a spring so that when the spring retracts or rebounds, it drives the movable tripping block connected to it to lock or engage with the corresponding tripping lock. The specific structures of these two existing opening and closing parts 16 (locking structures) will not be described in detail.

[0185]

Example 14

[0186] Figures 28 and 24 show a protective device for drivers and passengers in high-speed cars or buses. It is a semi-circular protective device consisting of a head protection device (support B2 and support connector C166) and a body protection device (support A1 and support connector Q168). The semi-circular protective device is mounted on the back of an existing driver's seat or passenger seat, forming a protective device that can open or close to one side and accommodate the upper body in the middle. The support A1 has a telescopic frame (including a telescopic rod 172) of variable length. For example, as shown in Figure 28, a left-right penetrating arm is provided on each side of the upper part of the head protection device (support B2). Two collars Q164 are connected, with their outer surfaces connected to the upper part (top outer surface) of the corresponding head protection device (support part B2). A connecting shaft Q165 passes smoothly through the two collars Q164 (the connecting shaft Q165 and the collars Q164 are rotatably connected). The exposed left and right ends of the connecting shaft Q165 are connected to the left and right sides of the upper part of the backrest B202. A tension spring Q163 is installed between the left and right sides of the head protection device (support part B2) and the corresponding connecting shaft Q165 or backrest B202. One end of each tension spring Q163 is connected to the outer surface of the left and right sides of the corresponding head protection device (support part B2) at the front. The tension springs Q163... The other end is connected to the corresponding connecting shaft Q165 or the corresponding backrest B202. The upper front part of the protective device (support part A1 or support part connector Q168) is connected to the lower part of the observation hole Q167 (the support part B2 below the observation hole Q167) on the head protection device (support part B2) as a whole. On the left and right sides and the middle part of the front of the protective device (support part A1), there are tubular support part connectors Q168 with a closed outer perimeter, a hollow middle, and an open lower part. The support part connectors Q168 on the left and right sides and the middle part are respectively connected to the left and right sides and the middle part of the corresponding support part A1 (arc shape) (the outer surface of the support part connector Q168 is connected to the outer surface of the corresponding support part A1). (Integrated), each support connector Q168 has a telescopic rod 172 inside (within the cavity) that can smoothly pass through (move up and down) inside the support connector Q168. The diameter of the telescopic rod 172 is slightly smaller than the diameter inside the support connector Q168 (the cavity). The upper part of each telescopic rod 172 extends into the interior of its corresponding support connector Q168, and the lower part (exposed end) of each telescopic rod 172 is connected to the corresponding support A1. The upper part of the middle support connector Q168 (the middle part of the front of the protective device) extends upward and connects to the upper corresponding support B2 (the lower part of the observation hole Q167 provided at the front of the head protection device). Inside (within the cavity) of the middle support connector Q168,Each component is equipped with a telescopic rod 172 and a telescopic spring Q170 that retracts (moves upward) a support part A1 connected to the telescopic rod 172. The upper end of the telescopic spring Q170 is connected to the corresponding upper support part B2, and the lower end of the telescopic spring Q170 is connected to the corresponding lower telescopic rod 172. A telescopic switch 171 (comprising a triplock Q177, a movable triplock Q176, a return spring Q173, a bracket Q175, and a handle Q174) is provided on the support part connector Q168 in the middle section to control the up and down movement of the telescopic rod 172. A movable triplock is provided on the outer surface (outer periphery) of one side of the support part connector Q168. Q176 has a transversely inserted movable trip hole 178 inside. One end of the movable trip hole Q176 passes inward through the movable trip hole 178 and abuts (rubs against) the outer surface of the corresponding telescopic rod 172 inside, or extends into a trip lock Q177 (a hole of a certain depth is opened on the outer surface of the corresponding telescopic rod 172) with a diameter slightly larger than the diameter of the movable trip hole Q176. The other end of the movable trip hole Q176 (the exposed end) is movably connected to the middle part of the upper half of the handle Q174 (a through-hole is provided on the upper handle Q174, in which a corresponding rotating shaft can be smoothly inserted, and the two ends of the shaft hole are exposed). On the rotating shaft on the side, a corresponding collar is fitted on each side. The outer surfaces of the two collars are fixedly connected to the parts that contact the corresponding movable hooks Q176 on both sides of the front. The upper end of the handle Q174 is connected to one end of the return spring Q173. The other end of the return spring Q173 is connected inward to the outer surface of the corresponding support connector Q168. The lower end of the handle Q174 passes through the bracket shaft hole Q179 at one end of the bracket Q175 and extends downward. The other end of the bracket Q175 is connected inward to the outer surface of the corresponding support connector Q168. On the left and right sides of the backrest B202, there is a connector that is connected to the support connector Q168 at the front. A groove 162, with a diameter slightly larger than the support connector Q168, engages with the corresponding support connector Q168. One side of each of the two grooves 162 is integrated with the left and right sides of the corresponding backrest B202. At the lower part of each of the two grooves 162, an inwardly opening (one side of the trip clip 180 is fixedly connected to the outer side of the corresponding groove 162, and the other side extends inward to the upper part of the groove 162, with an opening between it and the inner side of the corresponding lower groove 162) is provided. This allows the corresponding left and right telescopic rods 172 to only move up and down within the opening and not swing forward. When the driver or passenger sits on the seat B207, their back rests against the backrest B202 at the rear of the seat B207 (the support on the backrest B202 corresponding to the passenger's back is basically the same as that of existing car seats).Next, use your hands to pull the support parts A1 and B2 (the outer surfaces of support parts A1 and B2 that contact the corresponding inner surfaces of the car) upwards, which are pulled upwards by the two pull springs Q163 on the left and right sides, downwards. This causes the support parts A1 and telescopic rods 172 on the left and right sides of the protective device (support part A1) to respectively engage backwards in the two grooves 162 on the backrest B202 corresponding to them. At this time, use your hands to grasp the support A1 at the bottom of the protective device (support part A1) (the support part A1 connected to each telescopic rod 172) and pull it downwards to the lower rear part of the steering wheel (the steering wheel that guides the direction of vehicle travel) or the backrest of the front passenger seat. At the same time, the support part A1 drives the telescopic rods that are integrally connected to it. Together, 172 moves downward from inside the corresponding support connector Q168 (within the cavity) to the triplock Q177 on the upper part of one of the telescopic rods 172, engaging with one end of the corresponding movable triplock Q176 on one side (the movable triplock Q176 connected to the upper part of the handle Q174, under the action of the return spring Q173 on its upper part, extends inward into the triplock Q177). At the same time, the telescopic spring Q170 connected between the upper end of the telescopic rod 172 and the corresponding head protection device (support part B2) on its upper part is pulled downward. At this time, the lower parts of the telescopic rods 172 on both the left and right sides pass downward through the openings provided between the corresponding two grooves 162 and the triplocks 180 on the upper parts of the two grooves 162 respectively, and then extend towards the left and right triplocks respectively. At the lower part of card 180, the upper body is positioned within the space between the protective device (support A1), the head protection device (support B2), and the backrest B202. Both upper limbs extend forward from the upper limb channels Q169 on the left and right sides (the internal space of the upper limb channels Q169 can be appropriately increased to accommodate most users), allowing for flexible vehicle operation (hands on the steering wheel) or free movement. When the vehicle stops and it is necessary to get out, first press the lower part of handle Q174 inwards. At this time, the upper part of handle Q174, using bracket Q175 as a fulcrum, pries outwards at one end of the movable tripod Q176 connected to the upper part of handle Q174 and one end of the return spring Q173. Simultaneously, the other end of the movable tripod Q176 also moves outwards. As the device moves, it retracts outward from the trip lock Q177 (inside the hole) on the corresponding telescopic rod 172. At this time, the telescopic spring Q170 retracts upward and pulls the telescopic rod 172 and the support part A1, which is integrally connected to the lower part of each telescopic rod 172, upward together until the lower support part A1 and the lower part of the corresponding upper support part connector Q168 are in contact. Then, the body protection device (support part A1) and the head protection device (support part B2) are pushed forward and upward by hand. At the same time, under the action of the pull springs Q163 on the left and right sides of the head protection device, the outer surface of the front part of the body protection device and the head protection device are made to fit against the corresponding upper part of the roof (the inner surface of the upper part of the vehicle has a recessed groove with a corresponding shape to the body protection device).This structural design allows drivers or passengers to easily and quickly put on the device. When the upper body is inside the protective and head protection devices, because the head and body protection devices are connected to the corresponding backrest B202 at the rear, in the event of a violent collision with the front, left, or right side of the vehicle being driven or ridden, the amplitude of the body's violent forward, left, or right swaying will be reduced. Furthermore, if the body experiences severe vibrations inside the vehicle, and components on the steering wheel or frame at the front, the backrest B202 of the front seat, or the doors or frame on the left and right sides deform and then collide or be compressed against the protective and head protection devices, the deformation will be less severe. The protective and head protection devices safeguard the person inside from injuries caused by collisions or compression, especially in the event of a severe impact. They effectively prevent serious damage to the fragile cervical spine caused by large head movements. Furthermore, the telescopic rod 172 at the lower part of the protective device (support A1) and the support A1 integrally connected to its lower end can retract upwards to save space in the front of the roof when fitted to the vehicle, and extend downwards to reach under the steering wheel or the lower rear of the front seat back. This structure maximizes protection for the lower abdomen and surrounding organs. This design not only prevents severe injury to the internal organs during a violent collision but also reduces the device's size when retracted, saving interior space. Alternatively, the front (front half) and rear (rear half) sides of the protective device (support A1) and head protection device B2 (support B2) can be movably connected together (connected by the movable connecting part 15), and then the rear (rear half) sides of the protective device (support A1) and head protection device (support B2) can be set at the position of the backrest B202 (replacing the backrest B202) and then connected to the corresponding lower seat B207 or to the corresponding lower frame. Alternatively, a semi-circular support A1 corresponding to the front and left / right sides of the neck can be provided on the outer periphery of the neck (above the upper limb channel Q169). This support A1 is connected to the corresponding lower support A1 by a support connector Q168, forming a single unit. On the left and right sides of the support A1 on the outer periphery of the neck, a connecting frame is provided between it and the corresponding backrest B202 at the rear, spanning the shoulders (upper part of the shoulders). One end of each connecting frame is... The collar Q164 (ring) is fitted onto the outer surface of the upper part of the backrest B202 (on the backrest B202 bracket, which is also the location where it connects to the head protection device). The other ends of the left and right connecting frames connect from the left and right sides of the human head and neck to the sides of the corresponding front support A1 (the support A1 around the neck). An elastic liner 183 or an airbag liner 181 is pasted onto the inner surface of the support A1 around the neck, which means that the upper body and neck of the human body are placed inside the protective device (within the space supported by the support A1).This design exposes the head and face outside the protective device, making it suitable for use in vehicles traveling in urban areas. Due to the slower speeds, in the event of a collision, the amplitude of head and neck movement is minimized, reducing the risk of injury. To allow for better observation of the road and vehicle interior while the head is inside the protective device, the seat B207 and backrest B202 can be separated (with a movable connection). The backrest B202 can rotate independently (left and right), meaning it is rotatably connected to the rear of the seat B207. Specifically, the lower part of the backrest B202 (the part flush with the seat B207) is connected to the upper part of the adjusting component 6 (also the support for the backrest B202) as shown in Figure 7, or to the upper part of the retractable component 243 (also the support for the backrest B202). (When connected to the adjusting component 6, the swing component A5 can be removed; when connected to the retractable component 243, the adjusting component 6 and...) The lower part of the clamping component and the adjusting component 6 are located inside the shrinking component 243. The lower part of the shrinking component 243 is located inside the positioning tube 7. The lower part of the positioning tube 7 can be connected to the corresponding fixed bracket inside the vehicle body (connected to the corresponding internal surface of the vehicle body). When the upper body of the human is inside the protective device (the semi-circular protective device), the upper body can twist, causing the backrest B202 and the adjusting component 6 or the shrinking component 243 connected to the backrest B202 to rotate left and right together (the adjusting component 6 or the shrinking component 243 rotates inside the positioning tube 7). The connection structure between the adjusting component 6, the shrinking component 243 and the positioning tube 7 is described in detail in Embodiment 10 (and will not be repeated here).

[0187]

Example 15

[0188] The following describes how a snap-fit ​​or adhesive structure replaces the tension spring Q163 connecting the headrest and the rear backrest B202 (as shown in Figure 28). Specifically, a snap-fit ​​(buckle) structure made of two arc-shaped spring pieces made of elastic material, or an adhesive structure composed of a magnet and a metal piece attracted to it, is installed on the vehicle roof (inner surface of the roof) to replace the tension spring Q163 connecting the headrest and the rear backrest B202. The upper ends of the two arc-shaped spring pieces are fixedly connected to the corresponding vehicle roof, and the lower ends of the two arc-shaped spring pieces are respectively set as a space that can accommodate the lower corresponding support connector Q168 as it pushes upward between the two arc-shaped spring pieces. At the opening, the left and right curved spring pieces can move outwards at an angle (the lower ends of the two curved spring pieces are each set with a certain angle of inclination outwards). When the corresponding support connector Q168 is pushed upwards (towards the opposite inner side of the left and right curved spring pieces) from the opening between the angles of the two spring pieces, the left and right curved spring pieces move outwards under the action of elasticity. When the support connector Q168 enters the interior of the two spring pieces, the left and right angles at the lower ends of the two curved spring pieces contract inwards under the action of elasticity, making the opening between the left and right angles smaller and also locking the support connector Q168 (the upper end is set to be narrow at the top, wide in the middle, and narrow at the bottom) inside the left and right curved spring pieces. Alternatively, a magnet or a metal that attracts the magnet can be fixedly connected to the corresponding vehicle top (inner surface of the roof), and a metal that attracts the upper magnet or a magnet that attracts the metal can be fixedly connected to the outer surface of the corresponding support connector Q168 (outer surface of the protective device) at the lower part. When the support connector Q168 (protective device) moves upward to the top of the vehicle, the magnets and the metals that attract the magnets on the roof and the support connector Q168 (protective device) respectively come into contact with each other.

[0189]

Example 16

[0190] As shown in Figure 28, a locking structure (basically the same as the locking structure described in Embodiment 13) or an adhesive structure composed of a magnet and a metal that attracts it is provided at the upper end (upper part inside the cavity) of the support connector Q168 and the upper end of the corresponding telescopic rod 172 at the lower part, respectively, to replace the telescopic spring Q170 connecting the support connector Q168 and the lower part and the corresponding telescopic rod 172. Specifically, a pair of arc-shaped spring pieces are provided at the upper end of the support connector Q168 (upper part inside the cavity, which is also the part where the telescopic spring Q170 is connected). The arc shapes of the two spring pieces are aligned to form an arc-shaped cavity between them. The upper ends of the two spring pieces are fixedly connected to the upper end inside the corresponding support connector Q168 (connected to the outer surface of the corresponding support B2), and the lower ends of the two spring pieces are respectively... The lower extension (the two ends of the two spring pieces are respectively set to outward inclined angles) has an opening between the two lower spring pieces that allows the upper end of the corresponding lower telescopic rod 172 to be pushed upward into the two spring pieces (between the two angles). The upper end of the telescopic rod 172 is set as a locking part with a shape that is narrow at the top, wide in the middle, and narrow at the bottom. When the telescopic rod 172 and the support part A1 which is integrally connected to its lower end need to retract upward, the upper end of the telescopic rod 172 pushes open the two spring pieces (the lower opening) provided in the upper support part connector Q168. The section of the upper end of the telescopic rod 172 with a shape that is narrow at the top, wide in the middle, and narrow at the bottom extends into the space between the two corresponding spring pieces (inside). At this time, when the two opposing spring pieces retract inward, they lock the telescopic rod 172 (the section with a shape that is narrow at the top, wide in the middle, and narrow at the bottom) between the two spring pieces. Alternatively, a corresponding magnet and a metal that attracts the magnet can be fixedly connected to the upper end (upper part inside the cavity) of the support connector Q168 and the upper end of the corresponding telescopic rod 172 at the lower part, respectively. In this way, when each telescopic rod 172 and the support connector Q168 that is integrally connected to them need to retract upward, the magnet or the metal that attracts the magnet at the upper end of the telescopic rod 172 and the metal or the magnet that attracts the magnet at the upper end of the corresponding support connector Q168 (on the outer surface of the corresponding support B2, which is also the part where the telescopic spring Q170 is connected) are attached together.

[0191]

Example 17

[0192] As shown in Figure 28, inside the protective device (within the space supported by support A1) and the head protection device (within the space supported by support B2), there are respectively provided elastic linings 183 of a certain thickness, which are impact-resistant, soft and resilient, and are attached to their inner surfaces. These linings can be made of soft and elastic cotton, nylon, rubber, plastic, or elastic materials that can deform when squeezed and automatically rebound when there is no pressure. One side (front side) of the elastic lining 183 is connected (attached) to the inner surface of the protective device (within the space supported by support A1) and the head protection device (within the space supported by support B2), and the other side (rear side) of the elastic lining 183 is in contact with the corresponding human body or attached to the corresponding airbag lining 181.

[0193]

Example 18

[0194] As shown in Figures 28, 27, and 30, an air-filled inner liner 181 (airbag) is installed inside the head protection device (within the space supported by support part B2). One side of the airbag inner liner 181 (airbag) is adhered to the elastic inner liner 183 inside the head protection device (within the space supported by support part B2), including around the neck. The other side of the airbag inner liner 181 (airbag) contacts (rubs against) the head and neck of the human body. On one side (left or right) of the head protection device (support part B2) or the body protection device (support part A1), there is an inflatable bladder 182 (which can automatically expand after contraction) to replenish the airbag inner liner 181 with gas. One side of the inflatable bladder 182 is provided with a vent pipe 308 that communicates with its interior to deliver gas. One end of the vent pipe 308 is connected to one side of the inflatable bladder 182, and the other end of the vent pipe 308 is connected to the interior of the corresponding airbag liner 181. An inlet valve (one-way valve) and a suction valve (one-way valve) are connected to the vent pipe 308. A deflation valve 307 is provided on the vent pipe or the inflatable bladder 182 to release gas from the inside of the airbag liner 181 (airbag bag) to the outside, and a pressure valve 306 to automatically release gas when the internal gas reaches a certain pressure. Specifically, a sealing gasket bracket A401 (approximately funnel-shaped, wider at the top and narrower at the bottom) corresponding to the upper inlet valve 303 (arc-shaped or spherical) is provided inside the vent pipe 308 at the top of the inflatable bladder 182. The outer periphery of each component is integrally connected to the inner surface of the vent pipe 308. On the upper part of the sealing gasket bracket A401 and the corresponding surface of the intake valve 303 (inner surface of the funnel), a sealing gasket (made of elastic rubber or plastic) is attached to block airflow after the intake valve 303 and the sealing gasket bracket A401 are engaged. An intake valve spring 304 is provided on the upper part of the intake valve 303; when the airflow pushes the lower part of the intake valve 303 upwards, it retracts upwards along with the intake valve. One end of the intake valve spring 304 is downwards connected to the upper surface of the lower intake valve 303, and the upper end of the intake valve spring 304 is upwards connected to the upper spring connecting bracket A305. Both ends of 05 are connected to the inner surface of the corresponding vent pipe 308. On one side of the vent pipe 308, there is a vent valve 307 that allows excess gas to be discharged, and a pressure valve 306 that automatically discharges gas when the internal gas reaches a certain pressure. The pressure valve 306 has a pressure valve housing 503 (tubular) with open ends and a closed outer perimeter, located inside the vent pipe 308. At one end (the inward end) inside the pressure valve housing 503, there is also a sealing gasket bracket B502 (approximately funnel-shaped, with an elastic sealing gasket also attached to the inner surface of the funnel), which is narrower at the front and wider at the back, integrally connected to its inner surface. At the rear of the sealing gasket bracket B502, there is also a pressure valve 505 that matches it.One end of the pneumatic spring 506 is connected to the outer surface of the rear of the pneumatic valve 505. The other end of the pneumatic spring 506 is connected to the exposed spring connecting bracket D504. Both ends of the spring connecting bracket D504 are connected to the inner surface of the pneumatic valve housing 503. The outer peripheral surface of the rear end (the exposed end) of the pneumatic valve housing 503 is integrally connected to the inner peripheral surface of the corresponding vent pipe 308. A vent valve 307 is also provided at the bottom of the pneumatic valve 306. A vent valve housing 602 (tubular shape) has its front end extending inward into the vent pipe 308, while its rear end protrudes outside the vent pipe 308. The outer peripheral surface of the rear end of the vent valve housing 602 is integrally connected to the corresponding inner peripheral surface of the vent pipe 308. A funnel-shaped sealing gasket support C507, wider at the front and narrower at the rear, is also integrally connected to the inner surface of one end (rear end) of the vent pipe 308. A layer of elastic sealing gasket is also attached to the side of the bracket C507 opposite to the front-mounted vent valve 509 (spherical). A vent valve spring 601 is also provided at the front of the vent valve 509. One end of the vent valve spring 601 is connected to the corresponding vent valve 509, and the other end of the vent valve spring 601 is connected forward to the spring connecting bracket C603, which is connected to the front end of the vent valve housing 602. A vent tube 308 at the lower part of the inflation bag 182 is also provided with... The spring connecting bracket B309 is connected to the inner surface of both sides of the vent pipe 308. The spring connecting bracket B309 is connected to one end of the suction valve spring 402. The other end of the suction valve spring 402 is connected downward to the corresponding suction valve 403 (spherical shape) at the bottom. The lower part of the suction valve 403 abuts against the sealing gasket bracket A401 (which can also be a funnel shape that is wider at the top and narrower at the bottom, and an elastic sealing gasket is also pasted on the upper part of the sealing gasket bracket A401) connected inside the vent pipe 308. When the driver or passenger is seated inside the protective device consisting of the body shield, head shield, and corresponding backrest B202, the inflatable bladder 182 can be adjusted according to the size and build of the person. If the person is small and the space is too large, the inflatable bladder 182 can be squeezed by hand. At this time, as the inflatable bladder 182 retracts inward, the gas inside the bladder 182 flows upward along the vent pipe 308, simultaneously opening the air intake valve 303 and entering the interior of the airbag liner 181 through the vent pipe 308. The gas then pushes open the air intake valve 303... Simultaneously, the gas pushes the corresponding suction valve 403 to the closed state, causing the airbag liner 181 to expand in volume as gas enters. When the airbag 182 is released, it expands outward under its own elasticity (when returning to its original shape). At the same time, the airbag 182 draws external air inward and simultaneously opens the suction valve 403, allowing external gas to enter the airbag 182 through the suction valve 403. At this point, the airbag 182 replenishes the airbag liner 181 with gas once.The airbag 182 can be repeatedly tightened or loosened as needed to gradually expand the airbag liner 181. If too much gas is added to the airbag liner 181 or the space is too small, you can press your finger on the air tube 308 or the deflation valve 307 on the airbag 182 to adjust the amount of gas inside the airbag liner 181 so that the human body has a comfortable range in the space. If the air pressure inside the airbag liner 181 is about to exceed the pressure it can withstand, the high-pressure gas inside will push open the air pressure valve 505 to automatically release the excess gas. When a severe collision occurs on the front, left, or right side of a vehicle, the upper body and head / neck of the passenger are first impacted by the airbag liner 181 within the protective device (support A1) and head protection device (support B2). After the elasticity of the airbag liner 181 weakens, it then impacts the elastic liner 183 on the outside of the airbag liner 181. This two-layer (double) shock absorption significantly reduces the chance of injury to the upper body and head / neck during a severe collision. Furthermore, when passengers need to rest due to drowsiness during long journeys, they can inflate the airbag liner 181 by squeezing the inflatable airbag 182, causing the airbag liner 181 around the head and neck to expand and maintain an upright and relaxed posture. This makes cervical spine more comfortable when resting in the vehicle. In case a passenger becomes drowsy... In the event of a collision while the passenger is drowsy, the airbag liner 181 surrounding the head and neck will slow down or reduce the amplitude of head and neck movement, thereby protecting the head and neck and reducing injury, making travel relatively safer. Once the passenger is awake, they can press the deflation valve 509 on the vent pipe 308 or the airbag liner 181 to release excess air from the airbag liner 181, allowing for a comfortable range of motion in the head and neck while awake. The protective device can also have an airbag liner 181 similar to that inside the head protection device, and an inflatable liner 182 connected to and replenished with air can be installed on one side of the protective device or head protection device to adjust the internal space of the protective device.

[0195]

Example 19

[0196] Figures 28 and 29 show the body protection device (support A1) and head protection device (support B2), combined with a shock-absorbing vehicle seat that, in the event of a severe collision with the vehicle being inhabited, allows the passenger seat to twist in the direction of the impact under the action of retractable shock-absorbing components (including gas bags, gas tubes, liquid bags, liquid tubes that deform under pressure and automatically rebound when no pressure is applied, or springs, such as shock absorbers on motorcycles) and a seat torsion frame 201 (capable of swinging in any direction within a 360-degree range), thereby reducing internal damage to the head, neck, and internal organs caused by severe vibration during the impact. For example, Figure 29 shows the seat frame 203. The lower part has a seat bracket 205 with an upper part that is arc-shaped (spherical) and connected vertically downwards to the connecting parts. The lower part of the seat bracket 205 is connected to the corresponding lower frame (body). A seat torsion frame 201 with a diameter slightly larger than the upper part of the seat bracket 205 (also arc-shaped or a semi-circular hollow sphere) is fastened to the upper part of the seat bracket 205. Multiple seat connecting parts 204 are provided between the outer peripheral surface of the seat torsion frame 201 and the corresponding seat frame 203 (the connecting frame around the seat B207). One end of each seat connecting part 204 is connected to the corresponding seat torsion frame 201, and the other end of each seat connecting part 204 is connected outwards to the corresponding seat frame 203. Each part is provided with a vertically downward (or slightly inclined) shock absorber spring 206 between itself and the corresponding frame (body). The upper end of each shock absorber spring 206 is connected to or abuts against the lower surface of the corresponding frame connector 204, and the lower end of each shock absorber spring 206 is connected downward to the corresponding lower frame (body). (Alternatively, the multiple vertically or inclined shock absorber springs 206 can be replaced with a corresponding number of spring plates of the required length and appropriate width (which can be elastic steel plates, such as the shock absorber steel plates provided on mini trucks). One end of each spring plate is connected to or abuts against the lower surface of the corresponding seat connector 204 (the position where the shock absorber spring 206 is connected), and the other end of each spring plate is connected inward to the corresponding seat bracket 205 or... The lower part of the seat bracket 205 is connected to the vehicle body. The backrest B202 is connected to the seat B207 or the seat frame 203. When the passenger or driver sits on the seat B207 and their upper body enters the space between the protective device and the head protection device and the backrest B202 (the support part A1 or support part B2 is also connected to the backrest B202) or when the upper body is fixed to the backrest B202 by the existing seat belt, if a violent impact occurs in any direction of the vehicle (when the hollow spherical seat torsion frame 201 is fitted on the corresponding spherical seat bracket 205, the seat torsion frame 201 can swing in any direction within a 360-degree range without dead angles), the upper body of the person will swing violently in the direction of the impact.The upper body of the passenger will cause the backrest B202 and seat B207, which are strapped to it, to tilt to the corresponding side. At this time, the shock-absorbing spring 206 provided on the side of the seat B207 and seat connecting piece 204 will transmit the instantaneous shock force received by the passenger downward to the shock-absorbing spring 206, causing the corresponding shock-absorbing spring 206 to retract downward (it will retract downward when subjected to pressure from above). As the passenger, seat B207 and backrest B202 tilt to one side, the inertial force of the violent shock experienced by the upper body and head and neck during a violent impact is also relatively weakened. When the swing of seat B207 stops, the impact force when the upper body and head and neck collide with the soft or elastic inner lining 183 or airbag lining 181 inside the body protection device and head protection device will be greatly reduced. Therefore, the probability of injury to the upper body organs and head and neck of the passenger will be greatly reduced when the vehicle is involved in a violent impact.

[0197]

Example 20

[0198] For example, as shown in Figures 28 and 29, to allow the height of the protective device to be adjusted according to the user's height when connected to the seat and backrest to accommodate the needs of most people (the internal space of the upper limb channel Q169 can also be appropriately increased to accommodate most users), the seat B207 and backrest B202 can be movably connected. A lifting mechanism (the backrest B202 can be raised and lowered independently) can be provided at the lower part of the backrest B202. This lifting mechanism can include hydraulic or mechanical structures. For example, a hydraulic mechanism would connect the lower part of a hydraulic device, such as the hydraulic cylinder of a hydraulic jack, to a corresponding fixed part on the vehicle body. The frame (the floor plate inside the vehicle body) is connected, and the hydraulic cylinder has a piston that can move up and down. The lower end of the piston is in contact with the hydraulic oil inside the cylinder, and the upper end of the piston is connected to the lower part of the backrest B202 (located in the center left and right). The upper part of the backrest B202 is connected to the protective device (a semi-circular protective device). A backrest bracket (the left and right length of the backrest bracket is longer than the left and right length of the backrest) is horizontally installed at the rear of the backrest B202 and abuts against the rear of the backrest B202. The left and right sides of the backrest bracket cross over the corresponding backrest B202, then bend forward (90 degrees) and then bend downward to meet the seat corresponding to the lower front part. The two sides of B207 are connected as one piece. When adjusting the height of the backrest B207, the hydraulic pump (with a handle on the hydraulic pump) located on the cylinder is activated at the bottom of the seat B207. This causes hydraulic oil to push the piston upwards, which in turn pushes the connected backrest B202 and the protective device (semi-circular in shape) connected to the backrest B202 upwards. To lower the height of the protective device, the drain valve on the cylinder is activated to allow the hydraulic oil to flow back. Simultaneously, the piston causes the connected backrest B202 and the protective device (semi-circular in shape) to fall downwards (until the desired height is reached). (Close the drain valve). When the motor drives the hydraulic pump, the power switch connected to the motor's power cord can be toggled to control the motor's forward and reverse rotation (left or right). When the motor rotates forward, the hydraulic oil in the cylinder increases, and the hydraulic oil pushes the piston, the backrest B202 connected to the piston, and the protective device connected to the backrest B202 upward together. When the motor rotates in reverse, the hydraulic oil in the cylinder flows into the oil pump. At the same time, as the hydraulic oil in the cylinder decreases, the piston drives the backrest B202 connected to it and the protective device connected to the backrest B202 downward together (when it falls to the required height, the power switch and oil pump are turned off).The lifting mechanism of the mechanical structure can be configured as shown in Figure 12 as an adjustment structure for adjusting the height of the protective device (replacing the hydraulic jack). Specifically, the lower part of the backrest B202 is connected to the upper part of the adjusting member 6, and the lower part of the retractable member 243 is connected to the corresponding fixed bracket in the vehicle body. The side with the short shaft C108, shaft hole N244 and shaft hole G106 is set at the rear of the backrest 202 or on the left or right side of the backrest B202 (to facilitate pressing the exposed short shaft C108 to adjust the height of the backrest B202 and the protective device). The connection structure and working principle are described in detail in Embodiment 11 (and will not be repeated here).
