Description

Technical Field

[0001] The present invention belongs to the technical field of automobile protection, and in particular relates to a soft automobile shell protection device. Background Art

[0002] Traditional small cars mostly use rigid metal as the body covering material. Although it has a certain strength, it is easy to cause serious injuries to passengers in high-speed collisions.

[0039] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] Example 1: In this example, please refer to Figures 1 to 9 , a soft car body shell protection device, the soft car comprises a car body frame 1 and a soft body 17, the soft body 17 is arranged on the outer side of the car body frame 1;

[0041] The soft body 17 includes an outer shell 11 and an inner liner 12, the inner liner 12 is arranged on the inner side of the outer shell 11, and a cage-type body frame 111 is fixed between the inner liner 12 and the outer shell 11, the protection device includes a trigger component, a buffer component and an air cushion 6, a support frame 2 is fixed on the upper end of the inner liner 12, and a protective shell 21 is fixed on the upper end surface of the support frame 2, a plurality of fixing plates 22 are symmetrically arranged on the inner side of the support frame 2 about the vertical center line of the protective shell 21, a connecting spring 23 is fixed on one end of the fixing plate 22 away from the protective shell 21, and a support rod 3 is slidably connected to the inner side of the support frame 2;

[0042] A guide rod 31 is fixed to the upper end surface of the support rod 3, and a plurality of through holes 211 are opened on both sides of the protective shell 21;

[0043] A trigger assembly is provided inside the protective shell 21, and the trigger assembly includes a trigger member 4 and an insertion rod 41. A rotating shaft 24 is fixed inside the support frame 2, and the trigger member 4 is rotatably connected to the outer side of the rotating shaft 24. An annular groove 401 is provided at the upper end of the trigger member 4, and the insertion rod 41 is slidably connected to the upper end surface of the trigger member 4.

[0044] A buffer assembly is fixed to the upper end of the insertion rod 41, and a card plate 5 is provided on the lower end surface of the trigger member 4, a conductive copper sheet 51 is fixed to the upper end surface of the card plate 5, an air outlet 25 penetrating the support frame 2 is provided directly below the card plate 5, a gas generator 7 is fixed between the air outlet 25 and the card plate 5, and an air cushion 6 is fixed directly below the air outlet 25.

[0045] The cage-type body frame 111 is a cage-shaped body frame design of martensitic steel or dual-phase steel and carbon fiber network. This cage-shaped body frame design of martensitic steel or dual-phase steel and carbon fiber network not only enhances the overall strength of the structure, but also limits the spread of damage in the event of a collision. The soft body 17 is configured as a double-layer shell, namely an outer shell 11 and an inner liner 12, which increases the support and protection of the top of the car, so as to improve the roof's ability to resist deformation after the car rolls over.

[0046] In this embodiment, when in use, the ends of the plurality of support rods 3 away from the protective shell 21 are respectively welded to the side beams on the top of the car, and at this time, the air cushion 6 is located inside the through groove 121. When the car collides head-on, since there is an engine at the front end of the car that can protect the driver, the side beams are not easily deformed, so the trigger assembly will not be triggered, and the car will roll over, causing the car to directly contact the ground, causing the side beams in the soft body 17 to sag inward, thereby driving the support rods 3 to slide along the support frame 2 toward the protective shell 21, and The connecting spring 23 is compressed inwardly, and the direct impact between the support rod 3 and the fixing plate 22 is reduced by the connecting spring 23, so as to protect the support frame 2 and the fixing plate 22. When the support rod 3 moves, the guide rod 31 is driven to pass through the through hole 211 and inserted into the protective shell 21. The end of the guide rod 31 abuts against the side wall of the trigger member 4 to drive the trigger member 4 to rotate along the rotating shaft 24. At this time, the insertion rod 41 slides along the annular groove 401 to avoid interfering with the rotation of the trigger member 4, so that the bottom of the trigger member 4 squeezes the card plate 5, so that the upper edge of the card plate 5 The conductive copper sheet 51 is in contact with the gas generator 7 and energizes the gas generator 7, thereby causing a slight explosion of the guanidine nitrate in the gas generator 7, and forming a large amount of gas that is discharged from the air outlet 25 into the air cushion 6, thereby causing the air cushion 6 to expand rapidly. Since the two sides of the air cushion 6 are curled, the length of the air cushion 6 will increase during the rapid expansion process. When the air cushion 6 is fully deployed, its area can completely cover the top area of ​​the driver's head and the co-driver's head. Because the air cushion 6 is deployed inside the vehicle body, it can form a flexible partition between the driver and the ground. When the rescue personnel move the driver out of the car, the driver is protected, and the secondary injury caused by the friction between the car wreckage on the ground and the driver is reduced. The air cushion 6 extends outward along the inner wall of the inner liner 12, which can protect the driver's head. When the seat belt breaks or the driver slips out of the seat belt, a buffer layer is formed between the driver's head and the car inner liner 12, thereby reducing the driver's head from directly contacting the ground and spraining the cervical vertebra, which is beneficial to further protect the driver in the event of a rollover.

[0047] A through groove 121 penetrating the inner liner 12 is provided at the top, and the average thickness of the outer shell 11 of the soft body 17 is not less than 15 cm. The soft body 17 is made of a polymer material selected from polyurethane and acrylonitrile styrene acrylate copolymer, and the coverage area of ​​the soft body 17 is 30% to 100% of the total area of ​​the body.

[0048] In addition to the automobile chassis and cage-type frame being made of high-strength steel, iron, and aluminum alloy rigid materials, the vehicle body can be configured to be covered with a soft body 17, and the soft body 17 is made of a flexible material composed of polymer materials such as polyurethane, acrylonitrile styrene acrylate copolymer, etc. By replacing the rigid materials such as iron sheets, steel, and aluminum alloys of traditional vehicle bodies with a large amount of flexible materials, the vibration absorption capacity of the vehicle when it is impacted can be improved, which is beneficial for protecting passengers and drivers when they collide with the vehicle from inside the vehicle. Compared with direct collision with rigid materials, the flexible material of the soft body 17 can reduce damage to passengers. Since self-healing materials that can quickly seal cracks after damage are added to the soft body 17, the self-healing materials contain various nanofillers, such as carbon-based, silica, chitin, and cellulose nanocrystals. These fillers can participate in reversible cross-linking reactions, thereby improving the strength of the rubber, thereby promptly repairing small punctures and cracks.

[0049] If the side beam of the car rolls over without being deformed, the roof will collide with the ground, causing the roof to sag inward, thereby driving the buffer assembly to squeeze the plug rod 41 inward, thereby driving the plug rod 41 to squeeze the card plate 5 downward, causing the card plate 5 to fall off the support frame 2, and the conductive copper sheet 51 on the card plate 5 contacts the gas generator 7 and energizes the gas generator 7, thereby also triggering the trigger assembly, thereby ensuring that the trigger assembly can be triggered in time after the rollover and protecting the driver. In a small collision, that is, the side beam has not undergone obvious or large-angle deformation, or the roof has not received a strong impact, the top air cushion 6 will not be triggered. At this time, the driver can be protected only by the airbags around the driver, and the safety hazard above the driver is relatively small. If the upper air cushion 6 pops out, the air cushion 6 is easily affected by gravity and blocks the driver's line of sight, which is not conducive to the driver leaving the car on his own.

[0050] Two upper support plates 402 are symmetrically arranged on the upper end of the trigger member 4, and the positions of the upper support plates 402 correspond to the positions of the through holes 211. A lower support plate 403 is fixed to the lower end surface of the trigger member 4, and the lower end surface of the lower support plate 403 is in contact with the upper end surface of the card plate 5.

[0051] Since the two lower support plates 403 on the lower end face of the trigger member 4 are both in contact with the card plate 5, it is possible to prevent the vibration of the vehicle body during normal driving from causing the trigger member 4 to rotate and causing the upper support plate 402 and the through hole 211 to shift in position, thereby improving the stability of the trigger assembly. The through hole 211 is arranged parallel to the upper support plate 402. When the guide rod 31 passes through the through hole 211, it can evenly contact the side wall of the upper support plate 402, thereby facilitating the rotation of the trigger member 4. By using multiple upper support plates 402 and lower support plates 403, when the support rod 3 on any side slides inward, the trigger member 4 can be driven to rotate, which is beneficial to improving the stability of its triggering.

[0052] A plurality of protrusions 501 are fixed on the edge of the card plate 5 , and a card slot 201 adapted to the protrusions 501 is provided on the inner side of the support frame 2 , and the card plate 5 is made of plastic.

[0053] During the rotation of the trigger member 4, the lower support plate 403 presses the card plate 5, causing the card plate 5 to be concave downward from the center, and the protrusions 501 on both sides are moved out of the card slots 201 on the inner side of the support frame 2, so that the card plate 5 moves downward and is connected to the gas generator 7, and the gas generator 7 is triggered to start through the conductive copper sheet 51. The card plate 5 is fixed by snapping, and a certain force needs to be applied to the card plate 5 when triggered, which can reduce the looseness between the card plate 5 and the card slot 201 when the car is in a bumpy state, thereby reducing the possibility of accidental touch.

[0054] The buffer assembly includes a hydraulic rod 8, a support spring 9 and a steel plate 10. A plurality of hydraulic rods 8 are fixed to the upper end surface of the support frame 2, a steel plate 10 is fixed to the upper end of the hydraulic rod 8, and support springs 9 are arranged on the outer sides of the plurality of hydraulic rods 8.

[0055] A guide hole 212 is provided through the top of the protective shell 21 , and the movement range of the insertion rod 41 is limited by the guide hole 212 , and the upper end of the insertion rod 41 is fixed to the steel plate 10 .

[0056] When the roof of the car is under pressure, the external force it receives is transmitted to the steel plate 10, and the steel plate 10 can improve the supporting strength of the roof. Then the steel plate 10 moves toward the direction close to the support frame 2, and squeezes the support spring 9 to deform it, and transmits the remaining energy to the hydraulic rod 8, and then uses the support spring 9 to restore and gradually release the energy, thereby reducing the transmission of vibration and impact force, thereby improving the stability of the top support of the car, and when the support spring 9 is compressed to a certain extent, the steel plate 10 is recessed downward to drive the insertion rod 41 to move vertically along the guide hole 212 toward the direction close to the trigger member 4, so that the trigger member 4 and the rotating shaft 24 slide along the side wall of the support frame 2 toward the side close to the card plate 5, and open the card plate 5 to protect the driver.

[0057] The upper end surface of the air cushion 6 is provided with a plurality of air inlet holes 61, and the edges of the air inlet holes 61 are sealed with the edges of the air outlet holes 25. A guard plate 62 is hinged at the edge of the air cushion 6, and an elastic rope 63 is engaged with the side of the guard plate 62. The connection between the air inlet 61 and the air outlet 25 of the air cushion 6 is sealed and fixed, so that when a large amount of gas is emitted by the gas generator 7, it will enter the air cushion 6 through the air outlet 25 and the air inlet 61. At the same time, the air cushion 6 and the support frame 2 are fixedly connected, so that the guard plate 62 rotates along the hinge, and clips 631 are fixed at both ends of the elastic rope 63, so that the clip 631 slips off the guard plate 62. Since it is necessary to apply lateral force to release the fixation of the clip 631, and the force applied to the elastic rope 63 when the car is bumpy is in the up and down direction, the elastic rope 63 is reduced from slipping off the guard plate 62. In addition, the material of the elastic rope 63 is relatively soft, and after being subjected to a large impact force, it will undergo flexible deformation, and it is not easy to break compared to rigid materials, thereby reducing the safety hazard to people in the car.

[0058] A vehicle chassis 18 is arranged directly below the shell 11, and a first buffer 19 is fixed to the upper end of the vehicle chassis 18, a second buffer 20 is fixed to one end of the first buffer 19, and a bumper 21a is fixed to the end of the second buffer 20 away from the first buffer 19; the first buffer 19 includes a hydraulic piston rod 191, and a buffer spring 192 is sleeved on the outer side of the hydraulic piston rod 191.

[0059] Bumpers 21a are provided at both ends of the vehicle chassis 18, and a first buffer 19 and a second buffer 20 are fixed between the bumpers 21a. When the car is hit in the front and rear directions, since the material of the outer shell 11 is a flexible material, when the soft body 17 is impacted, it will sag inward and deform, and absorb the impact force during the impact. When the outer shell 11 sags inward, it will drive the bumper 21a to squeeze the second buffer 20, and push the second buffer 20 to squeeze in the direction of the first buffer 19, and drive the hydraulic piston rod 191 to slide inward, and use the hydraulic oil in the hydraulic piston rod 191 to further absorb the vibration energy during the impact, which is beneficial to further improve the impact resistance of the soft car.

[0060] Example 2: Please refer to Figure 10 to Figure 11 The protective device includes a compartment 13, a one-way air valve 14 and an air pump 131. The outer wall of the inner liner 12 is equidistantly provided with multiple compartments 13, and each of the multiple compartments 13 is connected with a one-way air valve 14, and one side of the compartment 13 is connected with an air pump 131.

[0061] When in use, the compartment 13 is located between the outer shell 11 and the inner liner 12. Compared with the traditional single-layer roof, it can enhance the overall strength of the car body and limit the spread of damage when the car rolls. When the rear passengers are not wearing seat belts, the passengers collide with the car inner liner 12 through multiple compartments 13, which can reduce the impact force of the collision between the passengers and the car inner liner 12 and reduce the injuries suffered by the passengers. The multiple compartments 13 are connected by a one-way air valve 14. When a compartment 13 leaks, it is blocked by the one-way air valve 14, so that each compartment 13 is relatively independent, which can prevent the gas in other compartments 13 from flowing into the gas-deficient compartment 13, so that the other compartments 13 can maintain structural integrity and functionality. Each compartment 13 can be inflated, and the gas anti-collision capability is increased on the basis of material buffering, which replaces the traditional anti-collision airbag and can provide 360-degree anti-collision protection for drivers and passengers.

[0062] The one-way air valve 14 includes a connecting pipe 15, a sealing plug 16 and a compression spring 161, and threaded protrusions 151 are fixed at both ends of the connecting pipe 15, a sealing plug 16 is slidably provided on the inner side of the connecting pipe 15, and a compression spring 161 is provided on the outer side of the sealing plug 16, and the end of the compartment 13 is connected to the air pump 131.

[0063] The threaded protrusions 151 at both ends of the connecting pipe 15 are tightened between two adjacent compartments 13, so that the multiple compartments 13 form a connected structure. When the compartment 13 with insufficient gas is one that is not directly connected to the air pump 131, the air pump 131 is used to pump air into the compartment 13. Due to the balance of air pressure in the compartment 13, the excess gas squeezes the sealing plug 16, and the compression spring 161 is deformed to form a gap between the sealing plug 16 and the pipe mouth of the connecting pipe 15, so that the gas is discharged from the compartment 13 close to the air pump 131. The air insufficiency chamber 13 moves outwards again until it enters the air-deficient chamber 13, and stops when the air-deficient chamber 13 is filled with air. The air insufficiency chamber 13 is connected by a one-way air valve 14, which can make each chamber 13 relatively independent and eliminate the need to add an additional air pump 131 to each chamber 13, thereby helping to save costs. The chamber 13 is located between the outer shell 11 and the liner 12, which improves the support of the outer side of the chamber 13 to prevent gas leakage and ensure the buffering capacity during impact, thereby improving the stability of the chamber 13.

[0064] The following is a further description of a soft automobile shell protection device provided by the present invention in conjunction with the accompanying drawings and implementation examples.

[0065] When in use, the ends of the plurality of support rods 3 away from the protective shell 21 are welded to the side beams on the top of the car respectively. When the car rolls over, the side beams of the car sag inward, thereby driving the support rods 3 to slide inward, inserting the guide rods 31 into the through holes 211, and driving the trigger member 4 to rotate, so that the lower support plate 403 at the bottom of the trigger member 4 squeezes the card plate 5, so that the card plate 5 is separated from the support frame 2, and the conductive copper sheet 51 at the upper end of the card plate 5 energizes the gas generator 7, so that the gas generator 7 sprays a large amount of gas through the air outlet 25 and the air inlet 61 into the air cushion 6, so that the air cushion 6 opens to both sides. During the expansion of the air cushion 6, an outward thrust is applied to the guard plate 62, so that The clips 631 at both ends of the elastic rope 63 slip off the guard plate 62, and then the air cushion 6 is spread between the roof and the driver, which is beneficial to protect the driver's head after rollover. If the car rolls over but the side beam of the car is not deformed, the roof hits the ground, and the roof and the steel plate 10 are affected by external force to move toward the side close to the support frame 2, and drive the insertion rod 41 to squeeze the trigger member 4 downward, thereby forcing the trigger member 4 to move toward the side close to the air cushion 6, thereby pressing the card plate 5 to disengage from the card slot 201, thereby also triggering the trigger component, and forming a barrier between the driver and the car wreckage on the ground to reduce secondary injuries caused by friction between the wreckage and the driver's body.
