Description

a flexible car technical field

The invention belongs to the technical field of automobiles, in particular to a flexible automobile.

Background technique

Automobiles have been around for hundreds of years. At present, ordinary cars are usually made of hard materials such as steel, and their weight is generally 1.2 to 2 tons. The greater the weight, the greater the impact force generated when a collision occurs. First of all, according to the kinetic energy expression E=0.5*m*v2, if the weight of a car is 2000kg, 100km/h is equivalent to 28m/s, so the kinetic energy generated by the car hitting at a speed of 100km/h is 0.5* 2000*28 ² =784000J, so the impact force at a speed of 100km/h is 784000J. If the impact force is converted into mass, if the speed of the object is very small, for example, 1m/s, then according to the energy conservation law E1=E2, 784000=0.5*m*1, m=1568000kg, which is quite More than 1568 tons weighed on this thing.

And because the existing automobiles are all rigid structures, the rigid impact produced during collision is a kind of instantaneous impact force, and this impact force will cause great damage to the occupants in the car. Because of the rigid structure of the car body, when a collision occurs, a huge acceleration will be generated to act on the people in the car. The following is illustrated by an example:

The vehicle hit a wall, a wall that would not deform. The vehicle was also very strong, it would not deform or rebound, and it was stopped directly. Then at this time, the speed of the vehicle instantly becomes 0, but people are different, they are separated from the vehicle, and the moment the vehicle stops, the person continues to move forward. Although the human body can stop quickly due to the action of the seat belt, the seat belt only surrounds the torso, and the head of the human body is subject to a force, which is pulled by the neck, so that the relative speed of the head decreases. Small. Then how much force the neck is subjected to, according to F=ma, that is, when the weight of the head remains unchanged, the greater the acceleration, the heavier the force on the neck. After the accident, people will definitely stop, the process from motion to stillness. It can be seen from the laboratory data of NCAP that generally speaking, the entire collision process is only 0.1 second or even shorter. In other words, when the speed is 50km/H, in this simplified model, the acceleration obtained by the head is 50/3.6/0.1=138m/s ² . That is 13.8 G. This value is actually not large, but assuming a head weighs 5kg, then the force on the neck is 690N. That is about 69kg. If this force is not done properly, the neck will be broken and dislocated, resulting in casualties. Similarly, other parts of the body, such as the brain, internal organs and other organs, will also be subject to greater forces in rigid collisions, which will lead to injuries.

Detailed ways

A flexible car proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims.

Referring to FIG. 1 to FIG. 5 , in one embodiment, a flexible vehicle includes a chassis, a power part, and a flexible body part 1 .

The power unit is located on the chassis. The vehicle body is arranged on the chassis, and at least part of the vehicle body is a flexible body part 1 . When subjected to an impact, the flexible body part 1 absorbs the impact by exacerbating its deformation through leakage.

Among them, the power part is the part of the device that drives the car forward. If it is a fuel car, it can include the engine, gearbox, transmission system, tires, control system, etc.; if it is an electric car, the engine, gearbox, etc. can be replaced by electric motors. . There may be many specific forms, which are not specifically limited here.

In this embodiment, a power part is set on the chassis to drive the car to move as a whole; furthermore, a body including at least part of the flexible body part 1 is set on the chassis. When the car is impacted, the flexible body part 1 will be impacted first, and the flexible body part 1 will absorb the impact force through its own deformation. The deformation of the flexible body part 1 includes two parts. One is that each unit body of the bladder structure The extrusion force causes the relative displacement between the single structures, which leads to the deformation of the flexible body part and generates friction. The frictional force F _is expressed, and the work done by the frictional force is: W ₌ F _{= S} , where _S is the relative displacement. W _friction comes from impact kinetic energy, which is finally absorbed by the capsule structure and converted into internal energy.

The second is that the bladder structure is compressed after being impacted, and the internal energy of the internal gas is increased after being compressed, which converts the kinetic energy of the vehicle into the internal energy of the gas, thereby absorbing the impact energy. The capsule structure is an elastic structure, so it can be simplified as an elastic model. According to Hooke's law, F _bomb =-kx, wherein F _bomb is elastic force, k is the elastic coefficient, and x is the compressed length. As the amount of compression increases, the elastic force F _bomb that resists the impact force also increases thereupon.

Or when the impact force is large, when the gas pressure in the bag reaches the discharge pressure, the gas will be discharged at high speed through the discharge port, and the gas will gain kinetic energy. When the pressure relief value starts to deflate, F _bomb reaches the maximum value at this time. F _bomb =F _vent , and the deflation model is simplified. Assuming that the deflation process is stable and deflated, then F _vent remains unchanged during the exhaust process. The impact energy absorbed in this process is: W _leak = F _leak S, where S is the compression amount of the deflated airbag, and the converted gas kinetic energy is: E _gas = 1/2mv ² , where E _gas is the kinetic energy obtained by the gas, m is the mass of the gas discharged, and v is the gas velocity. E _gas ≈ W _vent

It can be seen that the leakage of the internal medium further aggravates its own deformation to absorb the impact force, so that the impact force finally transmitted to the occupants of the vehicle can be greatly reduced, so as to reduce the damage caused by the collision to the occupants of the vehicle The invention solves the problem of large damage to people in the car during a rigid collision of the existing car.

Simultaneously, by arranging the flexible body part 1, the automobile can have a buffer when colliding, so that the acceleration produced by the automobile during the collision is smaller than the acceleration produced by the existing rigid automobile, effectively reducing the acceleration received by the occupants in the vehicle when colliding, Thereby, the injury caused to the occupants in the vehicle can be further reduced.

Further because the impulse is the product of the force and the time of action (F*t). The function of the impulse is to change the momentum of the object. The value of the impulse received by the object is equal to the change of the momentum of the object, that is: F*t=mv1-mv0. Because the flexible body has a certain elasticity and can leak, it elongates the mutual The time of action, so that the impact force becomes smaller, reducing the damage to the people hit outside the car

And because it is a flexible body, when a pedestrian outside the car is hit, the contact surface between the flexible body and the hit person becomes larger. Under the same impact force, due to the larger area, the pressure per unit area becomes smaller, further reducing the impact on the body. Injury from being hit outside the vehicle.

Wherein, the definition of a flexible vehicle may be that at least part of the flexible body part 1 is in a stable flexible state for all or part of the time. It is easy to understand all the time, that is, it is always in a flexible state that can absorb shocks; and in the case of part of the time, it can be set so that when it is required to absorb shocks or is in a state that is vulnerable to shocks, it can be filled by medium or other methods. The flexible body part 1 achieves a desired stable flexible state capable of absorbing shocks. For example, taking the flexible body part 1 as an airbag as an example, when the vehicle is stopped, it can be controlled to deflate, so that the airbag can be attached to the surface of the vehicle body or retracted into the vehicle body to reduce the volume; When the time comes, the airbag can be pumped into the air through the air pump, so that the airbag can be deployed to play a role of flexible protection; or when entering a driving scene with many people around, the airbag can also be inflated to avoid collisions or friction with passers-by and objects. The surface of the vehicle is damaged and the safety of pedestrians is protected; the inflation or deflation of the airbag can be controlled according to the actual application scenario, which is not specifically limited here.

Some specific settings and specific setting methods of the vehicle body of the present embodiment are described below:

Passive safety means that when a car collides, the car body can absorb the collision force through ingenious design, reduce the damage to people, and at the same time ensure that the occupants in the car can escape immediately. The safety design of the car is to absorb the impact force through the deformation and contraction of the car body at the moment of collision, and at the same time, through the cushioning devices such as seat belts and airbags, the degree of injury to the people in the car is minimized, and the structure of the car is strengthened to ensure that the vehicle body will not be damaged in the event of a car collision. It will not be deformed in the end, so as to ensure the occupants in the car. Just like when an earthquake occurs, it is not the walls that play a role in the safety of the house, but the steel frame structure. The only thing that can test the safety factor of a car is the crash test. The recognized test rule is the NCAP test implemented by the European Union, which includes two parts of frontal collision and side collision. Last year, China launched C-NCAP based on NCAP's five-star crash rating to score the safety factor of new cars. Consumers can also refer to this score. The NCAP evaluation programs implemented in the world mainly include U.S.NCAP (United States) IIHS (American Insurance Association) EuroNCAP (Europe) C-NCAP (China) ANCAP (Australia) JNCAP (Japan) KNCAP (Korea) LATINNCAP (Latin America) ASEANNCAP ( Southeast Asia).

The applicant found that there is a technical bias in the industry that the car body is set as a steel body, the better the collision safety performance is. The crash test results are represented by stars (★), there are five stars in total, the higher the star, the better the crash safety performance of the car.

Its specific content roughly includes two aspects, frontal and side collisions. The content of the crash test is different in different countries. In the United States, the 40% ODB frontal collision speed is 64 km/h, and the side collision speed is 50 km/h. In my country, the frontal 100% rigid wall collision speed is 50 km/h, and the 40% ODB frontal collision speed is 50 km/h. The speed is 64 km/h, and the side collision speed is 50 km/h. The crash test results are represented by stars (★), there are five stars in total, the higher the star, the better the crash safety performance of the car.

Based on the above-mentioned standards, the flexible body part of this embodiment, which includes at least one layer of vehicle body medium bladder from the outside to the inside, can absorb the impact force by having three kinds of energy absorption: frictional energy absorption, self-deformation energy absorption and leakage energy absorption. Meet the required standards and requirements. Specifically, when impacted, the adjacent vehicle body media bladders 101 rub against each other under the impact force, absorb the impact force and convert the impact force into internal energy.

Moreover, when the vehicle body medium bladder 101 is impacted by less than the preset discharge pressure, the vehicle body medium bladder 101 is compressed and absorbs the impact force, converting the impact force into elastic potential energy;

When the vehicle body dielectric bladder 101 is impacted by a preset discharge pressure, the vehicle body dielectric bladder 101 is first compressed to absorb the impact force, converts the impact force into elastic potential energy, and then breaks and leaks toward the impact surface to absorb the impact force And convert the impact force into the kinetic energy of the discharge medium. When the air pressure in the bag reaches _the pressure release value, the _deflation begins. At this time, the F _bomb reaches the maximum value _. The impact energy is: W ₌ F ₌ S, where S is the air bag deflation compression, and the converted gas kinetic energy is: _E = 1/2mv ² , where E is the kinetic energy obtained by the _gas , m is the mass of the gas to be discharged, v is the gas velocity. E _gas ≈ W _vent . Therefore, the required leakage energy absorption performance can be adjusted according to the medium density in the vehicle body medium bag layer 101 .

In this embodiment, the vehicle body medium capsule layer 101 can be set with a corresponding preset discharge pressure, for example, when the impact received is less than 30km/h collision, the vehicle body medium capsule layer 101 will not burst and discharge, only It will absorb the impact force by deforming itself. Similarly, when the impact is greater than or equal to 30km/h, the vehicle body medium bladder 101 will absorb the impact force by rupturing and releasing the internal medium on the basis of its own deformation.

From the perspective of mechanical research, the soft car in this embodiment is soft where it is soft, and rigid where it is hard. According to different stress conditions, part of the car body can absorb energy and disperse when it collides. , try to weaken the impact force, and achieve the purpose of protecting the driver and passengers to the greatest extent. On the condition that the manufacturer pursues a lightweight body as much as possible, it ensures the firmness of the passenger compartment and reduces the damage of the impact force to the occupants. The body structure can be used to For energy absorption, the strength of the impact force buffered by the front and rear energy-absorbing areas in the collision improves sufficient living space.

The specific implementation form of the flexible body part of the flexible automobile of the present embodiment is described below:

In this embodiment, the vehicle body can be completely formed by the flexible body part 1 , that is, the flexible body part is arranged on the chassis and surrounds the above-mentioned vehicle body. Due to the development of autonomous driving technology, the probability of vehicle-to-vehicle collisions will be greatly reduced, and the intensity of collisions between vehicles will also be greatly reduced. There is no need for future vehicles to retain a rigid body structure, and the flexible body not only protects passengers, but also It also makes pedestrians safer.

Further, since the weight of the vehicle is greatly reduced, the inertia of the vehicle during driving is reduced, so that the braking distance is shorter and the vehicle is safer to drive.

Moreover, due to the substantial weight reduction of the vehicle, the energy consumption of the vehicle during driving is greatly reduced, thus contributing to the dual carbon emission reduction of the automotive industry.

Referring to Fig. 18 to Fig. 21, as a transitional solution, part of the existing supporting frame structure 11 can still be retained on the basis of setting part of the flexible body part 1 for the vehicle body. When the flexible car is a car or other structure, the supporting frame structure 11 may include four beams and six columns, namely, a front anti-collision beam, a rear anti-collision beam, a bottom beam, an upper side beam, and two A-pillars and two A-pillars on both sides of the chassis. B-pillar and two C-pillars; and when the flexible vehicle is a structure such as an SUV, the support frame structure 11 may include four beams and eight pillars, that is, two D-pillars located on both sides of the chassis are further added on the basis of the above-mentioned four beams and six pillars; and When the flexible vehicle is a structure such as a truck or a truck, the support frame structure 11 may also be configured as a beam-and-column structure corresponding to an existing vehicle.

In this transition scheme, the flexible body part 1 can be arranged on the chassis independently of the supporting frame structure 11. For example, during the operation of the vehicle, the front and rear sides of the vehicle have the greatest probability of being impacted, so the flexible body part 1 can be placed on the chassis. The part 1 is provided on the front side and the rear side of the chassis so as to absorb the received impact. The flexible body part 1 on the front side and the rear side of the vehicle is used as the front anti-collision beam and the rear anti-collision beam of the vehicle. Compared with the existing hard anti-collision beam, the flexible body part 1 can absorb impact through its elasticity and leakage. Ability to provide protection for vehicles and pedestrians.

Referring to Fig. 20 and Fig. 21, the flexible body part 1 can also be arranged in combination with the support frame structure 11, that is, the flexible body part 1 can be arranged on the support frame structure 11. That is, the support frame structure 11 includes a plurality of interconnected structural members (i.e., beams and columns), on which connecting grooves can be provided, and the connecting ends of the flexible body part 1 can be embedded and fixed in the connecting grooves by bonding or the like. In the groove, the fixation between the two is realized. Further, after the flexible body part 1 is fixed, the flexible body part 1 can be set to protrude from the structure, and can also be set to be wrapped in the structure (forming an anti-collision flexible beam or anti-collision flexible column), which will not be described in detail here. limited.

Further, the connection between the flexible body part 1 and the above-mentioned structural parts can also be directly bonded or fixed to the supporting frame structure 11 without connecting grooves, or the flexible body part 1 can be set to partially pass through the structural parts. A permanent connection between the two.

Of course, the flexible body part 1 can also be arranged between adjacent beams and columns, so as to form a force-bearing and energy-absorbing part on the supporting frame structure 11 .

In other embodiments, the proportion of the flexible body part 1 in the vehicle body and whether other structures are provided on the vehicle body can be determined according to actual conditions, and are not specifically limited here.

The specific structure of the flexible body part 1 of the present embodiment is further described below:

In this embodiment, the flexible body part 1 includes at least one layer of vehicle body media bladder 101 . The vehicle body medium bag layer 101 is arranged on the chassis and is used to form the vehicle body after being filled with medium. Wherein, the connection method between the vehicle body medium bladder layer 101 and the chassis can be a fixed connection method such as adhesion or riveting, and it is only necessary to ensure that the relative positions of the two do not change.

Further, the vehicle body medium bladder layer 101 may specifically include several bladder-like structures 106 arranged in sequence (the bladder-like structures 106 may also be arranged to be connected to each other, so that when an impact is received, a certain pulling force may be generated through the connected parts to consume the impact. force). The arrangement of the capsule structure 106 can be various, it can be arranged horizontally and stacked one by one up and down, and it can also be arranged vertically and stacked one after the other. Of course, it can also be arranged obliquely. That's it. Wherein, adjacent capsule structures 106 may be connected by bonding or other connection methods. In other embodiments, the vehicle body medium bladder layer 101 can also be a separate bladder structure 106 similar to a hovercraft, which is not specifically limited here.

Referring to Fig. 22, further, in order to increase the friction area between adjacent bladder-like structures 106, so that a greater frictional force can be generated to absorb the impact force when receiving an impact, this embodiment also provides Matching depressions and protrusions are provided on the bladder-like structures 106, so that the contact area between the bladder-like structures 106 increases.

At the same time, the bladder-like structure 106 can be arranged to be staggered forward and backward, that is, part of the bladder-like structure 106 will protrude, so that when impacted, the bladder-like structure of the protruding part will move inward and communicate with the adjacent The relative movement of the bladder structure 106 creates friction to absorb impact.

Furthermore, since the capsule structure 106 of the outermost vehicle body medium capsule layer 101 is easily subject to friction or scratches, the material can be wear-resistant materials to prolong the service life. Certainly, the material of the outermost vehicle body medium capsule layer 101 can also be set as a fireproof or bulletproof material, so as to increase the performance of wear resistance and scratch resistance, and can have a certain fireproof and bulletproof performance.

In other embodiments, a fireproof or bulletproof material layer can also be provided on the outer or inner layer of the vehicle body medium bladder layer 101 or the bladder structure 106, also in order to increase the performance of wear resistance and scratch resistance, and to have a certain degree of fire resistance. Bulletproof.

In this embodiment, the material of the capsule structure 106 can be embedded with a reinforcing material, such as steel wire or braided wire, which has a certain structural strength, so that the capsule structure 106 can have a certain structural strength.

Furthermore, the inner cavity of the capsule structure 106 may also be filled with energy-absorbing materials, one for the purpose of maintaining the shape of the capsule structure 106, and the other for increasing impact resistance. Among them, the energy-absorbing material can be a flexible filler, such as foam filler or other flexible materials with certain strength and shaping ability; the energy-absorbing material can also be a brittle filler, such as a porous brittle structure. , can absorb impact by crushing.

Specifically, referring to Fig. 14 and Fig. 15, if the bladder-like structures 106 between adjacent vehicle body media bladder layers 101 are all arranged in the same direction, the corresponding bladder-like structures 106 between the two layers may correspond to the same direction Arrangement can also be staggered arrangement, or form a honeycomb arrangement.

In other embodiments, the bladder structures 106 in two adjacent vehicle body media bladder layers 101 may be arranged perpendicular to each other, and the adjacent bladder structures 106 may also be arranged in a staggered manner and not on a vertical plane. Of course, there are many other arrangements, which are not specifically limited here.

In other embodiments, the structure of the medium capsule layer 101 of the vehicle body can be configured as a honeycomb structure, that is, the entire vehicle body can be spliced by a hexagonal structure.

In this embodiment, the flexible body part 1 may further include at least one layer of flexible bladder layer 105 , and the flexible bladder layer 105 may be disposed between adjacent vehicle body medium bladder layers 101 . In specific arrangement, a flexible bladder layer 105 can be arranged between each vehicle body medium bladder layer 101 , or a layer of flexible bladder layer 105 can be arranged at intervals of several vehicle body medium bladder layers 101 , and the arrangement method is not specifically limited here. Wherein, the flexible bag layer 105 and the adjacent vehicle body dielectric bag layer 101 can be connected by bonding or other connection methods.

Referring to Fig. 8 to Fig. 13, in this embodiment, at least one leakage element is also included;

At least one flexible bladder layer 105 or bladder structure 106 is provided with a discharge passage 102, and the discharge element is correspondingly attached and sealed to the discharge passage 102, which is used to realize the leakage by deforming or opening the discharge element when the vehicle body is impacted. flow to absorb the impact. Preferably, each flexible capsule layer 105 and capsule structure 106 can have a drainage channel 102 .

In other embodiments, the arrangement of the leakage channel 102 and the leakage element can be that at least one leakage channel communicating with the flexible bladder layer 105 or the inner bladder structure 106 is opened on the outermost bladder structure 106. channel 102, the discharge channel passes through the discharge opening 104 opened on the flexible bladder layer 105 or the bladder structure 106 of the inner layer; the discharge element is attached to the discharge channel 102, thereby sealing the discharge channel 102 and making the flexible The bladder layer 105 or the bladder-shaped structure 106 of the inner layer is separated from the outside by the leakage element, which is used for absorbing the impact force through deformation or opening of the leakage when the vehicle body is impacted. It should be noted that the leakage channel communicates with the outermost bladder-like structure 106 and the flexible bladder layer 105 or the inner bladder-like structure 106, so the leakage element not only seals the flexible bladder layer 105 or the inner layer The openings on the outermost bladder-like structure 106 will also seal the outermost bladder-like structure 106, or the outermost bladder-like structure 106 will seal itself, so that the outermost bladder-like structure 106 will not leak.

When the impact is small, the vehicle body medium bladder layer 101 and the flexible bladder layer 105 only need to be deformed, which avoids damage to the vehicle body medium bladder layer 101 and the flexible bladder layer 105 under the condition of a small impact force.

Specifically, the discharge channel 102 can be in the shape of a round hole or a square, which is not specifically limited here; the purpose is to release the internal medium as soon as possible, and avoid the force generated by the rebound from causing harm to the occupants of the vehicle. The position where the discharge element is attached to the discharge channel 102 can be attached by applying adhesive 1031 , as shown by the shaded part in the figure.

The specific setting method is as follows:

Step 1. As shown in FIG. 9 , first stick the inner wall surface of the outermost bladder structure 106 to the outer wall surface of the flexible bladder layer 105 or the inner bladder structure 106 through an adhesive 1031;

Step 2, as shown in FIG. 10 , release the medium, flatten it and make holes on it to form the above-mentioned discharge channel 102;

Step 3, as shown in Figure 11, then apply adhesive 1031 on the discharge element (except for the position of the discharge opening 104 corresponding to the flexible capsule layer 105 or the capsule structure 106 of the inner layer), attach and place the discharge element The flow opening 104 is sealed.

Thus, as shown in FIG. 12 , the inner flexible bag layer 105 or the inner bag-like structure 106 is separated from the outside through the leakage element.

Wherein, the thickness and material of the leakage element can be determined according to various strength levels required by the leakage element. Depending on the impact force, control whether the discharge element bursts, and the time sequence of the discharge element bursting at different positions, so as to control the release of the corresponding discharge channel 102 and the speed, flow and direction of the medium in the discharge element, and absorb as much as possible The impact force, or direct the impact force to a specific direction, so as to protect the safety of the occupants.

It should be noted that the location of the discharge channel 102 and the discharge element is not a position that is easy to receive a collision, but when the vehicle body receives an impact, the flexible vehicle body transmits the impact force to the position of the discharge element, and the discharge The flow element is squeezed, and the leakage element breaks or opens, thereby guiding the liquid or gas in the flexible bladder layer 105 or the inner bladder structure 106 to flow out, thereby forming a deformation at the leakage position, so that the vehicle avoids impact as much as possible. The direct collision of the position (that is, to wipe or swipe from the initial impact position) can also absorb the impact force at the same time, so the position of the discharge channel 102 and the discharge element should be the position where the vehicle body most needs to be deformed. The essential purpose of the bleeder element is to absorb impact forces through the outermost body media bladder, the flexible bladder 105 or the inner bladder 106 through deformation and exacerbated deformation by the outflow medium. Of course, in other embodiments, the location of the discharge channel 102 and the discharge element may also be other locations on the vehicle body, which is not specifically limited here.

In this embodiment, the drainage element may be a passive drainage unit. For example, the passive bleed unit may be a burst membrane 103 separately provided at the bleed channel 102 for absorbing impact force by rupturing the bleed when receiving an impact.

In this embodiment, the leakage element may also include an active leakage unit and a control part. The control part is used to detect the vibration information received by the flexible body part 1 or perform early warning perception, and output the discharge information to the corresponding active discharge unit according to the vibration information or early warning information, and control the active discharge unit to discharge the flow.

Wherein, the active leaking unit can be a device that leaks through extrusion, such as an air valve for deflation of an inflatable toy or a tire, or a plug assembly with an active leaking function. For example, a mechanical structure can be set to connect the plug that is arranged on the flexible bag layer 105 or the bag-shaped structure 106 of the inner layer. When impacted, the mechanical structure pulls out the plug so that The liquid or gas flows out to achieve the purpose of deformation.

The active leakage unit can also be a sealing clip clamped at the discharge channel 102. In the clamped state, the flexible capsule layer 105 and the capsule structure 106 are in a sealed state. When the leakage information is received, the sealing clip is controlled to open and the leakage flow Road 102 will open.

The active leakage unit may also include a burst membrane and at least one active burst portion corresponding to the burst membrane 103 . The bursting membrane fits and seals the active bursting part of the discharge channel 102 and is respectively installed on the bursting membrane 103 for actively breaking the corresponding bursting membrane 103 . And each active bursting part is connected with the signal of the control part.

Wherein, the active bursting part is a physical rupture unit, a chemical rupture unit or a heating rupture unit. Specifically, the physical rupture unit can be an object with a sharp point, such as a needle or a knife; the chemical rupture unit can cause the rupture membrane 103 to be damaged by releasing chemical substances; the heating rupture unit can be an electric heating wire arranged on the rupture membrane 103 , the rupture film 103 is damaged by means of electric heating.

Further, the control unit may specifically include a control unit and a detection unit that are signal-connected to each other. The detection unit is a vibration sensing unit and/or an early warning sensing unit. If it is a vibration sensing unit, the vibration sensing unit can generate corresponding vibration information based on different vibration intensities and output it to the control unit, and the control unit can trigger and output rupture information according to the corresponding vibration information. If it is an early warning sensing unit, the early warning sensing unit can be a radar or other sensor installed on the car, and the control unit is the central management system on the car. The central management system triggers and outputs rupture information according to the early warning information of the sensor. Of course, the control unit can also comprehensively judge whether to output the leakage information to the corresponding leakage switch or the active rupture part according to the vibration information and the early warning information.

In other embodiments, whether the active rupture part destroys the burst membrane 103 can also be directly triggered by the mechanical structure provided on the vehicle according to the vibration intensity.

In this embodiment, the leakage flow of the flexible bladder layer 105 and the bladder structure 106 can be set as an orderly leakage flow. For example, a plurality of leakage channels 102 may be provided on the flexible capsule layer 105 and the capsule structure 106, and corresponding leakage elements may be installed respectively. When there are two discharge passages 102, an active discharge unit and a passive discharge unit can be installed respectively, and the discharge threshold corresponding to the active discharge unit can be set as 30km/h. The discharge threshold can be set to be impacted by 50km/h (as a redundant design). When the active discharge unit is not activated normally when the impact is received, the passive discharge unit can still break the discharge to absorb the impact force. Certainly, when there are two leakage passages 102, two passive leakage units or active leakage units with both leakage thresholds of 40 km/h can also be set, which can also achieve the purpose of redundant design, and no specific limitation is made here. .

Further, the bursting membrane or the leakage channel switch covered by the flexible capsule layer 105 and the capsule structure 106 can be designed from the outside to the inside so that under a certain mass, it can burst and leak when the impact is 20 kilometers per hour, and 30 kilometers per hour.

By setting the flexible car in this embodiment to be different according to the impact force, the impact force can be reduced through deformation and standardized leakage. It can not only protect the passengers in the car, but also protect the pedestrians on the road. Because impact damage to the human body includes two aspects, one is the impact force, and the other is the acceleration; from the perspective of protecting the passengers in the car, the discharge time is relatively long, which can reduce the acceleration of the impact, and the impact from the outside is At the angle of hitting people, the faster the discharge speed is, the smaller the impact force will be.

The multi-layer capsule structure can not only weaken the impact on pedestrians outside the car through the rapid deformation and rupture of the surface capsule structure 106, but also prolong the discharge time and reduce the impact through the deformation and rupture time difference of the multi-layer capsule structure 106. When the acceleration is high, the occupants in the car can be better protected.

In this embodiment, both the flexible bladder layer 105 and the bladder-like structure 106 can be liquid bladders or air bladders, which can be selected according to specific requirements; since the liquid has a strong buffer capacity, the liquid bladders are used to absorb impact through rupture; and The compression ability of the gas, that is, the deformation ability of the airbag is strong, so the airbag can be used to absorb the impact force through deformation. The above-mentioned flexible bladder layer 105 can be an integral annular structure, or several independent structures can be arranged between the vehicle body medium bladder layers 101 , which is not specifically limited here.

Of course, in other embodiments, the flexible capsule layer 105 and the capsule structure 106 can also be filled with fluid solid particles, or liquids of different viscosities, or gas-liquid mixtures, gas-solid mixtures, solid-liquid mixtures, etc. , not specifically limited here.

Further, the shape and thickness of the flexible bladder layer 105 and the bladder structure 106 can be determined according to requirements, and can be set according to the buffer capacity and structural strength requirements of the current site, which are not specifically limited here.

Further, the bladder-like structure 106 can specifically be circular tube-shaped air bladders or liquid bladders one by one, which can be used for gas or liquid and cooperate with the flexible bladder layer 105 to form a bladder assembly in use.

Among them, the bladder structure 106 of the vehicle body medium bladder layer 101 is mainly used for filling gas or liquid and maintaining the formed vehicle body shape and structural strength. The flexible capsule layer 105 is mainly used for damage and impact absorption because of the relatively large amount of medium therein.

When the bladder structure 106 of the structural medium bladder layer inside is a liquid bladder, the temperature inside the vehicle can be adjusted to the comfortable temperature of the human body by controlling the temperature of the liquid in this part of the fluid bladder.

Likewise, the vehicle body dielectric bladder layer 101 and the flexible bladder layer 105 can play a buffering role, so that the acceleration transmitted to the occupants of the vehicle during a collision is significantly reduced, thereby reducing the injury to the occupants of the vehicle.

Referring to Fig. 18, in this embodiment, when the flexible body part 1 is arranged on the front side and the rear side of the chassis, the flexible body part 1 on the front side and the rear side can be arranged as an annular flexible bag layer arranged on the chassis 105 , the cavity formed in the middle of the ring-shaped flexible bag layer 105 is filled with the above-mentioned bag-shaped structure 106 , so as to form a flexible anti-collision structure.

Referring to Fig. 19, in another embodiment, when the flexible body part 1 is arranged on the front side and the rear side of the chassis, the flexible body part 1 on the front side and the rear side can also be arranged as an outward facing surface. The flexible bladder layer 105 and the bladder-shaped structure 106 are arranged in sequence on the outwardly facing arc surface of the flexible bladder layer 105 to form a flexible anti-collision structure.

Some extended implementations of the flexible car of this embodiment are further described below:

When impacted, the impact on one or more sides of the body can be transmitted to the front of the body, thereby reducing the local impact and impact. Specifically, the cross structure 2 can also be configured as a flexible structure, that is, in the form of an air bag or a water-filled bag.

In this embodiment, the flexible car can further include several flexible seats 3, which are arranged on the chassis and are used to protect the human body when the car is impacted. The flexible seat 3 can be made of an air bag or a liquid bag. Referring to Fig. 16, when the car is impacted, the wrapping structure 9 provided on the flexible seat 3 can wrap the back and the head of the human body to play a protective role and reduce the damage to the people in the car. Wherein, the wrapping structure 9 may be made of an air bag or a liquid bag.

Furthermore, when the flexible seat is composed of a liquid bag, the temperature of the liquid can also be adjusted so that the occupants of the vehicle can feel a comfortable temperature.

Referring to Figures 2 to 5, in this embodiment, the chassis may include a first chassis 4 and a second chassis 5 that are rotatably connected; specifically, the first chassis 4 and the second chassis 5 may be rotatably connected by a pin shaft, And the rotation axis of the pin shaft is higher than the first chassis 4 and the second chassis 5 .

When needing to be folded, each air bag on the first chassis 4 and the second chassis 5 and the medium in the liquid bag are emptied, and then these bladders have just all been pasted on the first chassis 4 and the second chassis 5. Then the second chassis 5 can be rotated around the pin shaft and covered on the first chassis 4, so as to complete the folding, so that the volume of the car is significantly reduced when not in use, which is convenient for storage and takes up little space.

Referring to Fig. 16, further, a sliding locking structure 10 can also be provided at the rotational connection of the first chassis 4 and the second chassis 5, when the first chassis 4 and the second chassis 5 are fully unfolded, the sliding locking structure 10 That is to say, it can slide between the first chassis 4 and the second chassis 5, thereby fixing the relative position between the two and ensuring that they will not rotate.

Wherein, since the steering wheel 6 is needed in the non-automatic driving state of the automobile control part, the connection position between the rotation transmission shaft of the steering wheel 6 and the chassis can be set as a rotational connection, then when it needs to be folded, the steering wheel 6 can be rotated and put down to the chassis If it is a self-driving vehicle, there is no need to set the steering wheel 6, so there is no folding problem.

In this embodiment, a medium filling device, such as an air filling device or a water filling device, may also be provided on the chassis for inflating or filling the air bag or the liquid bag. There are many types of existing media filling equipment, so we will not give examples one by one here.

Referring to FIG. 6 and FIG. 7 , in this embodiment, the flexible vehicle may further include housing shells 7 arranged on both sides of the chassis, and at least one pair of multi-axis rotors 8 are rotatably connected in each housing shell 7 . When traveling on land, the multi-axis rotor 8 is accommodated in the housing 7 . When traveling in the air, the multi-axis rotor 8 rotates out of the housing 7 to the working position.

Further, the flexible car may also include water propellers arranged on the chassis, so that the vehicle can advance in water.

The reason for setting the multi-axis rotor 8 and/or the water propeller is that the body part of the vehicle in this embodiment adopts a flexible structure, which is an air bag or a liquid bag. Compared with the existing vehicle, the weight is greatly reduced. For flying, the weight reduction makes flying easier, and the vehicle can be driven to take off without consuming a lot of energy or a high-power motor; for water propulsion, the low weight, especially if it is all airbags, can easily Floating on the water surface, so water propulsion can be easily realized by adding a water propeller.

In this embodiment, the flexible vehicle may also include a thermal insulation bucket for storing hot or cold medium, and is used to guide the thermal energy or cold energy in the thermal insulation bucket to the required position of the vehicle body through pipelines. For example, when the vehicle is an electric vehicle, if it is used in a region with a relatively high latitude, the performance of the battery will be greatly attenuated due to low temperature, so the heat energy in the heat preservation bucket can be output to the battery through the pipeline to maintain its required working temperature. As another example, both the flexible bag layer 105 and the bag-like structure 106 in this embodiment can be liquid bags, and the temperature in the car can be maintained to reach a certain level by introducing heat or cold energy in the thermal insulation bucket into the flexible bag layer and the bag-like structure. comfortable temperature. There can be many application forms of the medium in the thermal insulation barrel, and no specific limitation is made here.

In this embodiment, the materials of the various parts constituting the flexible body part (such as the flexible bladder layer 105, the bladder structure 106, the vehicle body media bladder layer 101, etc.) can be made of fireproof materials. Further, the material of the flexible seat and other components can also be set as a fireproof material, which is not specifically limited here.

The flexible car of this embodiment adopts a flexible body part, and compared with existing vehicles, the weight can be greatly reduced. When applied to the field of new energy vehicles, for example, power consumption can be greatly reduced, battery life can be improved, and energy saving and emission reduction can be achieved. Purpose. In the field of new energy vehicles, the flexible body part of this embodiment can also store flame-retardant or fire-extinguishing media in an airtight bag close to the battery, and quickly release the media in an accident to prevent the battery from burning and gain time for passengers to escape.

At the same time, in line with the technological progress of autonomous driving, due to the development of autonomous driving technology, the probability of vehicle-to-vehicle collisions is greatly reduced, and there is no need for vehicles to retain a rigid body structure, while the flexible body not only protects passengers, but also makes pedestrians safer .

Further, because the weight of the vehicle is greatly reduced, the braking distance is shorter and the vehicle is safer to drive. The setting of the flexible body in this embodiment greatly reduces the production cost of the automobile, and creates a new application field for the research and development of non-metallic materials in the automobile industry because it creates a new direction for automobile research and development.

In this embodiment, the flexible vehicle may further include at least one medium filling and discharging capsule layer and a medium filling and discharging unit.

The filling and discharging medium capsule layer is correspondingly arranged on the outside of the vehicle body or in the vehicle body (for example, a slit or an opening can be opened on the vehicle body, and the filling and discharging medium capsule layer in the contracted state is correspondingly arranged in it, while the filling and discharging medium capsule layer in the expanded state will protrude from the gap or opening and spread out to the outside of the vehicle body) to form a protective layer on the outside of the vehicle body.

The medium charging and discharging unit is located in the vehicle body, and the output end of the medium charging and discharging unit is connected to the filling and discharging interface of the medium capsule layer, and is used to fill or discharge the medium capsule layer according to the road conditions.

Specifically, the medium filling and discharging medium bag layer can be an airbag, and the medium filling and discharging unit can be an air pump, and the airbags are respectively arranged on the left and right sides or all four sides of the vehicle body. When the vehicle enters a congested or narrow road with a lot of traffic, the airbag can be inflated by the air pump, and the airbag can form a protective layer on the corresponding position of the vehicle body to avoid collisions or friction with passers-by and objects, causing damage to the surface of the vehicle. or endanger the safety of pedestrians. Especially in the state of automatic driving, the protective layer formed by the airbag can help the car slowly pass (squeeze) through the crowd or congested road under the guidance of the vehicle perception and early warning system. When the vehicle is driving at high speed, the gas in the airbag can be released under safe conditions, reducing the overall volume of the vehicle body, reducing air resistance, and improving efficiency; when the vehicle perception and early warning system anticipates the danger of collision in advance , the airbag can also be inflated by the air pump, and the airbag can form a protective layer at the corresponding position of the vehicle body to reduce the harm of collision.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and equivalent technologies, they still fall within the protection scope of the present invention.
