Description

Collision protection device Technical field

The invention relates to the field of collision protection, in particular to a collision protection device.

Background technique

According to statistics from the World Health Organization, about 650,000 fatal falls occur every year in the world, making it the second leading cause of death from unintentional injuries after road traffic injuries. The highest incidence is among the elderly over 65. . People who have been injured by falls and become disabled, especially the elderly, are at great risk of needing long-term care and admission to institutions in the future. Statistics show that for every five elderly people admitted to the hospital for wrestling, one will eventually die within a year, and the rest will also bring about tremendous changes in their lives. The personal and social medical care expenses caused by fall-related injuries are enormous. In addition, when the elderly fall outside, they often fail to receive timely help and miss the best time to rescue them. At present, there is still a lack of intelligent and effective protection devices for fall injuries in the market.

At present, in the field of human body protection (impact, fall, etc.), there are no more than two types of existing technologies and methods in the world. One type is based on inert physical structures (different from active response to emergencies, pop-ups or changes), such as cushions, helmets, and soft linings. It does not have the ability of intelligent judgment, and there is no problem of folding and releasing. The other is based on the rapid inflation of the airbag in sudden situations to form an air cushion.

In terms of function, the physical structure is inert, and the volume is bloated and cannot be collapsed. Fall protection for the fragile body of the elderly, as an article worn by the elderly, it is almost impossible to achieve lightness and compactness and comprehensive protection at the same time. In addition, the use of airbags for anti-fall has major technical flaws, which are fatal and difficult to overcome. The most important disadvantage of airbag technology when applied to anti-fall is that its opening is one-time. However, for one-time use, there is a fundamental contradiction in the protection of falling. When a stagger occurs, the factors that determine whether to fall or not in the next moment include whether the ground is slippery at that time, the physical condition of the elderly, mental condition, etc. A large number of uncertainties. If you choose not to open the airbag at this time, you may have missed a real fall. If you choose to open it, there is a high probability that the airbag did not fall, but the airbag was abandoned. All of these must be judged at the moment when the fall has not been completed. For disposable airbag protection technology, this is an insurmountable dilemma.

To overcome the difficulty of fall protection, a protection technology that can be used repeatedly and recyclably is needed, which should be based on a reversible physical process that is completely different from the inflation process. As long as there is a high-risk action like staggering, open it. If it does not fall, use it the same time after folding.

Another problem with airbags is that airbags that are inflated by high-pressure gas may cause secondary injuries to many elderly people whose bones are already particularly weak. Because if it is low pressure, it cannot be inflated and deployed quickly, and high-pressure airbags are too hard for a considerable number of elderly people. In fact, even the most mature car airbags sometimes cause secondary injuries. This is a contradiction that is difficult to reconcile, especially for the elderly who require special soft treatment.

The protective component of the present invention includes a stretched frame, which is not formed in the unexpanded state; and in the unfolded state, a frame with supporting force (pressure resistance and tensile strength) is formed. The stretch forming frame includes one or more frame units, the frame unit includes a plurality of supporting units and one or more movably connected, each supporting unit can be folded into a space-saving supporting unit and the supporting unit as close as possible through the movably connected The state can also be expanded to a state where a hollow frame is formed between the supporting units through the movable connection. The support unit is divided into a frame of a fully rigid support unit, a frame of a fully elastic support unit, a frame of a combination of rigid and flexible support units, a frame of a combination of rigid and elastic support units, elastic and flexible The frame of the support unit combination, and the frame of the rigid, flexible and elastic support unit combination.

The support unit of the generative frame is a one-dimensional support unit, and also includes one of a two-dimensional support unit and a three-dimensional support unit, or a combination of two support units. The one-dimensional rod-like support unit of the frame support unit is one or more combinations of long tube, curved rod/tube, wire, and rope; the two-dimensional support unit is a hard two-dimensional frame and a hard piece. One or more combinations of, elastic two-dimensional frame, elastic sheet, film, net, and textile; the three-dimensional shape support unit is one or more of rigid three-dimensional frame, elastic three-dimensional frame, spring, and special-shaped spring combination. The movable connection of the frame includes shaft hinged connection, shaftless hinged connection, connection between flexible support unit and rigid or elastic support unit and elastic connection. The movable connection between the units plays a role in transmission and distribution of force , And mutually enhance the role of support. The stretchable frame for active protection can be cycled repeatedly between the unexpanded and fully expanded states.

The unfolding process of the frame is that for the unfolded frame, there is a driving force to conform to the pre-determined expansion direction of the structure, and the frame unit that is in direct physical contact is pulled, and the support units of the frame unit are relatively displaced through their movable connections. , Form a hollow frame.

For the case of multiple frame units, the frame unfolding process is further. The frame unit shares the support unit or can be movably connected to transmit the traction force to the adjacent frame unit, causing the relative displacement of the support unit to form a hollow frame, and so on. Towing to complete the deployment of all frame units. The folding process of the unfolding frame is the inverse process of the unfolding process. Each frame unit and its supporting unit follow the same reverse movement trajectory, restore the unfolded state, and can be repeatedly unfolded. The stretched frame for active protection is a single integral frame after unfolding. The stretched frame includes several frame units after unfolding, and the connection between the units includes: connection through movable connections, or sharing support units with adjacent frames, or a combination of the above. Multiple frame units can be arranged and combined in different ways to form a frame assembly, including: multiple similar frame units arranged or combined in a specific order, multiple similar frame units arranged or combined in a non-specific sequence, and multiple different frame units Arrange or combine in a specific order, and arrange or combine multiple different framework units in a non-specific sequence.

The frame is in the unexpanded state, and the supporting unit is in a tightly fitting or flat state. The hollow frame formed after it is expanded has elastic support force for one or more force directions. The elastic support force comes from the force generated by the frame body. With limited deformation, the frame converts the external pressure into the deformation stress of the entire frame and the squeezing/pulling force generated on the adjacent frame.

For a frame with multiple frame units, when a frame is hit and squeezed by an external force alone, the transmission of external pressure is transmitted in multiple directions along the frame unit and movable connection shared with adjacent frame units, spreading to the bottom A layer of adjacent frame units or/and supporting units, and so on, can disperse the local impact pressure to the non-contact position of the structure or the overall buffer structure, and cause it to deform and absorb the impact energy.

The stretch forming frame includes a support unit and a stretch unit, and the support unit and the stretch unit are combined into one or several non-solid structures (that is, stretch structures) during development. The stretch forming frame includes one or several stretch structure units, the stretch structure unit includes a support unit and a stretch unit, and the support unit and the stretch unit are connected to each other. The stretch unit is a flexible material, which is in a relaxed or folded state when it is not unfolded. After being stretched, it unfolds to form an elastic or rigid support unit, and forms a stretch structure together with the support unit. The tensile structure is one or a combination of films, belts, nets, ropes, and textiles. The supporting unit is one or more of a bar, a beam, an arc, and a sheet frame, and after unfolding, it forms a stretching structure together with the stretching unit. The supporting unit may be a sheet-like structure, including various rigid or elastic sheets, and hollow sheets, which form a stretched structure together with the stretch unit after unfolding. The supporting unit may be an elastic frame, that is, the frame can be significantly deformed under pressure, and can be restored to the previous shape after the pressure is relieved, and form a stretching structure together with the stretching unit after unfolding.

The supporting unit is a multi-joint structure, and multiple rigid supporting units are formed by more than two joints (movably connected) to form a multi-joint movable frame. The multi-joint movable frame can perform a variety of compound unfolding movements (such as multi-layer compound unfolding), and after unfolding, it forms a stretch structure together with the stretch unit.

The various support units mentioned above can not only directly support the impact pressure that occurs on the support unit itself, but also indirectly support the impact that occurs on the tension unit through the tensile unit it supports. pressure.

Preferably, the tubular units arranged in an array include two or more tubular units with different cross-sections.

The unfolding frame may include multi-pleated units (pleated structure) arranged in an array. When not developed, the multi-pleated units have a near-planar structure or a highly densely folded (lack of voids) structure. After being developed, the multi-pleated units Either bulge and deform along the folds, or expand along the creases from a high-density folded state. In both cases, a hollow sheet-like frame structure is formed. The multi-fold units in the fold forming frame are connected to each other at the folds. It may also be that the multi-pleated units arranged in an array are folded by forming folds on a sheet-like material. The sheet-like folding structure can be lined or connected to the frame structure corresponding to the fold to improve the supporting force. The sheet material can have hollow parts, thin parts and thick parts. The materials used in the multi-pleated unit include paper, special reinforced paper, plastic, polymer materials, carbon fiber sheets, glass fiber sheets, other inorganic fiber sheets, metals, etc.

The stretched frame for active protection is composed of single or multiple brackets. Each bracket is composed of fully rigid, fully elastic, rigid and elastic support units, and rigid and flexible support units. When it is not developed, the stent is flattened or folded and has no supporting ability. When it is developed, the stent is partially erected, and the supporting units form a stable structure with a certain angle between each other to form a supporting structure for the impact direction. Once the stent is developed, a lock can be used to lock the stent structure to prevent the stent from returning to the unexpanded state under force. The frame formed after the stent is developed is flexible. The elasticity can come from the bracket itself, or it can come from the spring connected with the rigid frame edge to provide elastic cushioning when the frame edge is displaced due to impact. Multiple support bodies can be arranged in an array to form an area support function.

The present invention provides a dynamic retractable protective body based on a stretch forming frame. The protective body contains a single or multiple identical or different stretch forming frames, which can be unfolded in a specific unfolding manner under the drive of a power unit to realize protection against impact .

Preferably, the protective body is formed by a plurality of supporting units far away from each other, which are connected and penetrated through the same large tensile unit after being expanded, so that the area covered by the tensile unit forms an elastic protective layer, wherein the tensile unit can More than one layer.

The shield may also include a power drive unit, which is one of a spring, a torsion spring, a motor, and the system's own elastic stress, or includes a power drive unit made of memory metal material, which deforms by controlling temperature changes, Drive the frame to expand or collapse. The composition of the protective body can include supporting structures other than the flexed frame, such as elastic sponge, colloid, air cushion, and non-flexible frame frame structure.

Driven by the power unit, multiple stretch forming frames can be deployed from one side, from opposite sides, and more from multiple sides and multiple directions. Driven by the power unit, multiple flexing frames can radiate outward from the center, or rotate outward from the center. Driven by the power unit, multiple stretch forming frames can be deployed in translation from the starting point to the end point or along the track. Driven by the power unit, multiple developing frames can be deployed in stages or in stages.

The protective body can be retracted. After the protective function is completed, the structure can be folded and restored to the state before unfolding, and can be used repeatedly.

detailed description

Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although specific embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

Example 1

Figure 1 shows a schematic diagram of the composition and operation of the collision protection device of the present invention. The collision protection device 1 includes a protection component 101, a sensing component 102, a calculation processing component 103, a control component 104 and a power drive component 105. The protective member 101 has a collapsed state and an expanded state, and a reciprocal cyclic change can be realized between the collapsed state and the expanded state. The sensing component 102 senses and calculates the triaxial acceleration of the collision protection device and the triaxial angular acceleration of the collision protection device. The sensing component 102 sends its sensing results to the calculation processing component 103. The calculation processing component 103 generates instructions based on the sensing results of the sensing component 102 and through preset rules. The control component 104 generates instructions according to the calculation processing component. The command generated by 103 controls the power drive assembly 105 to deploy the protective component 101. After the protection function is completed, the protection component 101 is folded to the state before opening, and the sensing component 102, the calculation processing component 103, and the power drive assembly 105 are also restored to the original state.

Example 2

As shown in FIG. 2, the collision protection device is a wearable device for the human body. The collision protection device is fixed on the shoulders of the human body and includes a collision protection component 21. The collision protection component 21 is a folding structure, and the folding structure includes a fixing frame 201, a supporting unit 202, and a stretching unit 203, preferably a flexible film, a connecting piece 204 and a locking component 205. The fixing frame 201 is fixed to the shoulder of the human body, for example, can be attached to a human body garment or fixed by forming a clamping structure with the shoulder of the human body. The supporting unit 202(s) are arc-shaped (including elliptical arc-shaped) rigid brackets, which are preferably metal materials or hard polymer materials. Multiple supporting units 202 and fixing frames 201 are used through both ends of the arc The connecting pieces 204 (preferably torsion springs) are fixed to each other (preferably the torsion springs are connected to the fixing frame 201). The supporting unit 202 can rotate around the connecting piece 204. The connecting piece 204 forms an axis that allows the supporting unit 202 to rotate. The supporting unit 202 rotates and separates from each other around the connecting member 204 to provide power. The outside of the supporting unit 202 is covered with a flexible film 203. When in the folded state, the supporting units 202 are joined together and close to each other side by side, and the flexible film 203 is in a folded state. The connecting member 204 can provide power to the outermost one of one end of a row of the support units 202 that are close to each other (farthest away from the fixing frame 201), so that the outermost one rotates relative to the connecting member 204 to drive the flexible film 203 to open, and then The flexible film 203 drives the remaining supporting units 202 to rotate around the connecting piece 204 to be separated from each other. In this case, the locking member 205 locks the supporting unit farthest from the fixing frame 201.

When the wearer of the collision protection device is about to fall, a forward or backward motion will occur. The sensing component on the collision protection device senses and calculates the three-axis acceleration and three-axis movement of the collision protection device in real time. Angular acceleration, the calculation processing component on the collision protection device generates an instruction according to the sensing result of the sensing component through a preset rule, and the control component controls the locking component 205 to unlock according to the instruction generated by the calculation processing component, thereby multiple supporting units 202 rotates around the connecting member 204 under the power provided by the connecting member 204 (torsion spring). When the plurality of supporting units 202 are separated from each other, the flexible film 203 on the outside thereof is stretched to a flat state. Another option is that the connecting member 204 only provides power to the outermost one of the plurality of supporting units 202, and it rotates relative to the connecting member 204 to drive the flexible film 203 to expand, and then the flexible film 203 drives the remaining supporting units 202 around the connecting member 204 After rotating, the supporting units 202 are separated from each other until the flexible film 203 is in a flat state. After the flexible film 203 is stretched flat, it has the effect of tensioning the connected ends, and finally forms a supporting structure. This design only needs to rotate 180 degrees in the opening direction. It can become a protection against the human head. The supporting structure forms an elastic support before the wearer of the impact protective clothing falls and hits the ground, so as to prevent the wearer's head from being injured by the collision with the ground. After the collision protection device is used and folded, it is restored and reused.

Example 3

As shown in FIGS. 3 and 4, the collision protection device 31 includes a semicircular arc-shaped first supporting unit 301, a straight rod-shaped second supporting unit 302, and a straight rod-shaped third supporting unit 303. Both ends of the arc of the first support unit 301 are respectively fixed to the shoulders of the human body, the first end of the second support unit 302 is movably connected to the midpoint of the arc of the first support unit 301, and the second end is connected to the first end of the third support unit 303. The second end of the third supporting unit 303 is connected to the power driving component 304 (preferably a spring). When the collision protection device 31 is in the folded state, the first support unit 301, the second support unit 302, and the third support unit 303 are all attached to the back of the human body. The second support unit 302 and the third support unit 303 is located in the linear guide rail, and the spring 304 is locked by a locking member (not shown in the figure) in a compressed state.

When the wearer of the collision protection device is about to fall backwards, the sensing component on the collision protection device senses and calculates the three-axis acceleration and the three-axis angular acceleration of the collision protection device in real time. According to the sensing result of the sensing component, the calculation processing component generates instructions through preset rules. The control component controls the unlocking of the locking component according to the instructions generated by the calculation processing component. The power driving component 304 then releases the elastic force to push the third support unit 303 advances along the track on the back of the human body, and then pushes the second support unit 302 out of the track, due to the force of the second support unit 302 moving in the direction of the first support unit 301 and the fixed positions at both ends of the arc of the first support unit 301 The reverse force causes the connection point of the arc of the first support unit 301 and the first end of the second support unit 302 to move away from the human body, and finally form a convex expanded state, thereby preventing the human back and head from directly hitting the ground. After the collision protection device is used and folded, it is restored and reused.

Example 4

As shown in Figures 5 and 6, the collision protection device is a wearable device that can be fixed on the waist belt 41, and the collision protection component 42 is located outside the waist belt. The collision protection component 42 includes a first support unit 401, a second support unit 402, a third support unit 403, and a fourth support unit 404.

Example 7

Figures 10 and 11 show a vehicle-mounted collision protection device. The collision protection component 71 includes a fixing frame 705 for fixing the protection component 71 on the vehicle, a number of (the number is not limited by the figure shown) supporting units 701 with rectangular contours of the same size, and covering the supporting unit 701 and fixing The elastic membrane 702 outside the frame 705. The supporting unit 701 may be a rectangular frame or a plate-shaped sheet. The supporting units 701 can be attached to each other and attached to the fixing frame 705 to form a collapsed state of the collision protection component 71. The supporting units 701 to which the collision protection component 71 is attached form a row, and the supporting unit located at the outermost side (away from the fixing frame 705) on one side is locked by the locking component 703 in the folded state. One side of each supporting unit 701 is fixed by the same torsion spring 704, and the torsion spring is fixed on the fixing frame 705. Each supporting unit 701 can rotate around the torsion spring 704 to form a folded state and an expanded state.

In the folded state, the supporting units 701 are close to each other side by side, and the elastic membrane 702 is in a folded state. When unfolded, one end of a row of the supporting units 701 that are close to each other side by side (away from the fixing frame 705) One of them can rotate relative to the torsion spring 704 to drive the elastic membrane 702 to expand, and then the elastic membrane 702 drives the remaining support units 701 to rotate around the torsion spring 704 to be separated from each other.

Suppose the rule generates instructions, the control component controls the locking component 703 to unlock according to the instructions generated by the calculation processing component, the multiple support units 701 rotate around the torsion spring 704 under the driving force of the torsion spring 704, and the multiple support units 701 are separated from each other At the time, the outer elastic membrane 702 is stretched to a flat state. As an alternative, the outermost one of the multiple supporting units rotates relative to the torsion spring 704 to drive the elastic membrane 702 to expand, and then the elastic membrane 702 drives the remaining supporting units 701 to rotate around the torsion spring 704, and the supporting units 701 are separated from each other until the elastic membrane 702 is in a flattened state. The elastic membrane 702 becomes a continuous elastic flat surface after being flattened. Due to the tension support of the connected outermost support unit 701 and the fixing frame 705, an elastic support structure is finally formed as a whole. The design can become a protection for the human head as long as the opening direction is turned 180 degrees or more.
