Description

Technical Field

[0001] This invention belongs to the field of automotive safety technology, and specifically relates to a headrest for escaping drowning without altering the vehicle's structure. Background Technology

[0002] In recent years, there have been numerous incidents of drowning caused by vehicles falling into water and being unable to escape in time. The probability of accidents and injuries when a car accidentally falls into water is very high. Nowadays, cars are an important means of transportation for people's travel and transportation. The number of cars per capita is also increasing. People's requirements for car safety and comfort are getting higher and higher, and their attention to this issue is also constantly increasing. The high mortality rate of car falling into water accidents poses a great threat to people's property and life safety. Therefore, it is necessary to provide emergency self-rescue devices for vehicles falling into water to increase the protection of people's driving safety.

[0003] However, in the emergency situation of a vehicle falling into water, the people inside the car are prone to panic. Since there are no escape tools in the car after it falls into the water, and the car is very likely to stall when it enters the water, the windows cannot be opened in time, and people cannot escape from the car in time. Even if they escape from the car in time, without any life-saving equipment, they will still waste time to save themselves, which may lead to drowning. Therefore, we need to propose a water escape headrest that does not require any changes to the car structure. Summary of the Invention

[0004] To address the above problems, the present invention provides a flood escape headrest that does not require alteration to the vehicle structure, comprising:

[0005] A car headrest and a headrest bracket installed inside the car headrest. The headrest bracket is provided with two sets of water-assisted restraint mechanisms arranged symmetrically, and the movable ends of the two sets of water-assisted restraint mechanisms are located on the outside of the car headrest. The movable ends of the two sets of water-assisted restraint mechanisms are interlocked to achieve the binding of the upper body of the person who falls into the water.

[0006] The car headrest has a foam filling inside, and the upper end of the headrest bracket is located inside the foam filling. The foam filling supports the person who falls into the water, enabling them to float in the water.

[0007] The bottom of the car headrest is equipped with a safety hammer installed below the headrest bracket, which is used to break the vehicle glass and cut the seat belt.

[0008] Furthermore, the shape of the foam filling is adapted to the internal shape of the car headrest, one side of the car headrest is sewn with a support for the driver's head to rest against, and the other side of the car headrest is sewn with a pocket.

[0009] Furthermore, both sets of the water-assisted restraint mechanisms include a storage box, the inner cavity of which is equipped with a spring mechanism. The spring mechanism has a rotating shaft, and both ends of the rotating shaft are wrapped with safety restraint straps. The ends of the two sets of safety restraint straps away from the rotating shaft pass through the storage box and are fixedly connected to a sleeve. A connecting shaft is inserted between the two sets of sleeves, and a buckle is installed on the outer middle of the connecting shaft.

[0010] Furthermore, two sets of guide plates that pass through the safety restraint straps are fixedly connected to one side of the storage box. The two sets of guide plates are inclined relative to one end of the storage box, and the inclined sides of the two sets of guide plates are adapted to the outer side of the car headrest.

[0011] Furthermore, the storage box is fixedly connected to two sets of connectors on the side adjacent to the guide plate, and multiple sets of connecting bolts for bolting to the headrest bracket are inserted into both sets of connectors.

[0012] Furthermore, the headrest support includes a support beam, in which two sets of reinforcing beams and a mounting base plate are fixedly connected from top to bottom. One side of each of the two sets of connecting parts is respectively attached to one side of the two sets of reinforcing beams. Each set of reinforcing beams has threaded holes on one side for installing multiple sets of connecting bolts.

[0013] Furthermore, the upper surface of the mounting base plate is in contact with the lower surface of the foam filler, the support beam is U-shaped, and the upper end of the support beam is located inside the foam filler. Multiple sets of limiting grooves are opened on the outer sides of both ends of the support beam.

[0014] Furthermore, the lower surface of the mounting base plate is located on the outer bottom of the car headrest, and a first bracket and two sets of second brackets are fixedly connected to the lower surface of the mounting base plate. The two sets of second brackets are arranged in parallel, and the first bracket is staggered and perpendicular to the two sets of second brackets.

[0015] Furthermore, the safety hammer includes a hammer handle and a protective sleeve made in one piece, and a conical hammer head for breaking vehicle glass is installed inside the protective sleeve. The hammer handle and the protective sleeve are integrally arranged in a T-shape.

[0016] Furthermore, a slotted side groove is provided on the outer side of the hammer handle, and a seatbelt cutter is installed in the slot. Anti-slip texture is provided on the outer side of the hammer handle.

[0017] The beneficial effects of this invention are:

[0018] This invention utilizes the cooperation of a car headrest, headrest bracket, foam filling, and a water-assisted restraint mechanism. The buoyancy of the foam filling keeps the person floating on the water's surface, providing a life-saving condition after the vehicle has fallen into the water. Simultaneously, the water-assisted restraint mechanism secures the headrest to the chest, preventing it from separating from the person due to panic after falling into the water. This ensures the upper body of the person remains above water, enabling them to take self-rescue actions and preventing drowning, thus guaranteeing the safe escape of occupants after the vehicle enters the water.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, this embodiment of the invention provides a water escape headrest that does not require alteration to the car structure. It includes a car headrest 1 and a headrest bracket 2 installed inside the car headrest 1. The headrest bracket 2 is provided with two sets of water-assisted restraint mechanisms 5 arranged symmetrically, and the movable ends of the two sets of water-assisted restraint mechanisms 5 are located on the outside of the car headrest 1. The movable ends of the two sets of water-assisted mechanisms are interlocked to achieve the binding of the upper body of the person who has fallen into the water.

[0030] The car headrest 1 has a foam filling 8 inside, and the upper end of the headrest bracket 2 is located inside the foam filling 8. The foam filling 8 supports the person who falls into the water, enabling them to float in the water.

[0031] The bottom of the car headrest 1 is equipped with a safety hammer 7 installed below the headrest bracket 2, which is used to break the vehicle glass and cut the seat belt.

[0032] The shape of the foam filling 8 is adapted to the internal shape of the car headrest 1. One side of the car headrest 1 is sewn with a support part 6 for the driver's head to rest against, and the other side of the car headrest 1 is sewn with a pocket.

[0033] Specifically, the foam filling 8 is made of foam material with good buoyancy (such as NBR foam material, PVC foam material, EPE pearl cotton, etc., with NBR foam material as an example below), and its shape is adapted to the interior of the car headrest 1 to ensure tight filling and avoid uneven buoyancy or unstable support due to internal gaps. At the same time, it meets the buoyancy design requirement that the total buoyancy is greater than or equal to the total weight, ensuring the reliability of buoyancy. The support part 6 can improve the comfort of the driver's head when leaning on it, taking into account both escape function and daily use experience. The pocket on the other side (not shown in the figure, the pocket height is half of the car headrest 1) can store emergency small items (such as tissues, small tools), further increasing the practicality of the product without affecting the core function of the headrest.

[0034] It's worth noting that calculating the minimum volume of NBR foam material required hinges on the principle of buoyancy (Archimedes' principle), ensuring that the total buoyancy is greater than or equal to the total weight. The specific steps are as follows:

[0035] When a person and NBR material float together, the following condition must be met: Total buoyancy (F_buoyancy) ≥ Total weight (G_total)

[0036] Where: Total buoyancy F_buoyancy = (volume of water displaced by the human body + volume of water displaced by the NBR) × density of water × gravitational acceleration (g)

[0037] Total gravity Gtotal = (human body mass + NBR mass) × gravitational acceleration (g)

[0038] Since g can be canceled out, it simplifies to:

[0039] (V) 人排 +V NBR )×ρ 水 ≥m 人 +m NBR

[0040] Human body related parameters

[0041] Human body mass m 人 Calculated based on actual weight (kg), such as 60kg;

[0042] Human body density ρ 人 Approximately equal to the density of water (1000 kg / m³) 3 Since the human body includes bones and muscles, the actual height is slightly higher; it can be approximated as 1000 kg / m² when estimating. 3 (to simplify calculations)

[0043] The volume of water displaced by the human body, V 人排 Because of ρ 人 ≈ρ 水 When floating, V 人排 ≈m 人 / ρ 水 (e.g., for a 60kg human body, V)人排 ≈0.06m 3 ).

[0044] NBR foaming material parameters

[0045] NBR density ρ NBR The density of NBR varies depending on the expansion ratio, typically ranging from 30-100 kg / m³. 3 (Specific product parameters need to be checked, such as 50kg / m³) 3 The NBR volume is V. NBR : Quantity to be determined; NBR mass is m NBR :ρ NBR ×V NBR .

[0046] Substitute into the formula to calculate the minimum V NBR , with "m 人 =60kg, ρ 人 =1000kg / m 3 ρ 水 =1000kg / m 3 ρ NBR =50kg / m 3 For example:

[0047] (1) Substituting into the simplified formula: (0.06+V NBR )×1000≥60+50×V NBR

[0048] (2) Expand and organize: 60+1000V NBR ≥60+50V NBR

[0049] 950V NBR ≥0 (here, assuming ρ) 人 =ρ 水 The human body can already float almost perfectly; however, in practice, a correction should be made because the density of a person (ρ_human) is slightly greater than the density of water (ρ_water).

[0050] Corrected calculation (closer to reality, using ρ) 人 =1050kg / m 3 ):V 人排 =m 人 / ρ 人 =60 / 1050≈0.0571m 3

[0051] Substitute into the formula: (0.0571+V) NBR )×1000≥60+50V NBR

[0052] 57.1 + 1000V NBR ≥60+50VNBR That is, 950V NBR ≥2.9

[0053] It can be known that V NBR ≥2.9 / 950≈0.0031m 3 (That is, 3.1 liters, approximately 3.1 dm³) 3 It is equivalent to a cube with a side length of 14.6cm.

[0054] The above calculations show that NBR foam material of the headrest size can make a person weighing 60kg float. However, since the headrest type varies for each car model, it is not convenient to calculate the limit value.

[0055] It is worth noting that:

[0056] NBR density is the core variable: the lower the density (the higher the expansion ratio), the smaller the required volume. If ρ is used... NBR =30kg / m 3 Under the same conditions as above, V NBR ≈2.1dm 3 .

[0057] Safety redundancy: In actual use, a safety factor of 1.2-1.5 should be reserved to avoid insufficient buoyancy due to material aging or density changes after getting wet. For example, if the calculated value is 3dm... 3 The actual required size is 4-4.5 dm. 3 .

[0058] For example, if an escape headrest can float a person of standard weight, and the weight of the person who has fallen into the water is greater than the buoyancy of one escape headrest, then with five such escape headrests installed in a five-seat car (taking a five-seat sedan as an example), the person can use two of these escape headrest devices to ensure a safe escape from the water.

[0059] Shape influence: It is necessary to ensure that the material can completely wrap around or fix it to the human body to avoid dispersion, and the volume of water displaced is equal to the volume of the material itself (complete or mostly submerged, with only part of the material exposed when floating, which is already assumed in the formula).

[0060] Furthermore, both sets of water-assisted restraint mechanisms 5 include a storage box 51. A spring-loaded device 52 is installed inside the storage box 51. A rotating shaft 53 is provided on the spring-loaded device 52. Safety restraint straps 54 are wrapped around both ends of the rotating shaft 53. The ends of the two sets of safety restraint straps 54 away from the rotating shaft 53 pass through the storage box 51 and are fixedly connected to a sleeve 55. A connecting shaft 56 is inserted between the two sets of sleeves 55. A buckle 57 is installed on the outer middle of the connecting shaft 56.

[0061] The safety restraint strap 54 can be automatically retracted by the spring mechanism 52 (a common technology in the prior art, the principle of which will not be elaborated in detail). This prevents the restraint strap from being exposed or scattered for a long time, making it easy to store and reuse daily, reducing maintenance costs. The restraint straps are wound around both ends of the rotating shaft 53 simultaneously, which can enable the two sets of restraint straps to be pulled out quickly. With the help of the sleeve 55, connecting shaft 56 and locking buckle 57, the headrest can be fastened quickly and fixed to the upper body of the person (tied at the chest position). This effectively prevents the person from separating from the car headrest 1 after falling into the water, avoids loss of floating support, and improves escape safety.

[0062] Preferably, two sets of guide plates 510 are fixedly connected to one side of the storage box 51, through which the safety restraint strap 54 passes. The two sets of guide plates 510 are inclined relative to one end of the storage box 51, and the inclined side of the two sets of guide plates 510 is adapted to the outer side of the car headrest 1.

[0063] The guide plate 510 is tilted and adapted to the outside of the car headrest 1. On the one hand, it can guide the safety restraint belt 54 to extend smoothly along the preset trajectory, avoiding delays in escape time due to the safety restraint belt 54 getting stuck. On the other hand, it fits the shape of the car headrest 1, without compromising the overall aesthetics of the car headrest 1, and will not affect the feel during daily use. At the same time, it can reduce the friction wear between the safety restraint belt 54 and the edge of the car headrest 1, extend the service life of the safety restraint belt 54, and ensure normal function in emergency situations.

[0064] In addition, two sets of connectors 58 are fixedly connected to the side of the storage box 51 adjacent to the guide plate 510, and multiple sets of connecting bolts 59 that are bolted to the headrest bracket 2 are inserted into both sets of connectors 58.

[0065] The connector 58 (in a T-shape) is bolted to the headrest bracket 2 by multiple sets of connecting bolts 59, which can firmly fix the storage box 51 to the headrest bracket 2, preventing the storage box 51 from falling off due to bumps and impacts after the vehicle falls into the water. This ensures that the water-assisted restraint mechanism 5 can be used stably in an emergency. At the same time, the design of multiple sets of connecting bolts 59 further improves the connection strength, adapts to the weight load of foam materials and personnel, and ensures the reliability of the structure.

[0066] In a further preferred embodiment, the headrest bracket 2 includes a bracket beam 21, and two sets of reinforcing beams 24 and a mounting base plate 23 are fixedly connected from top to bottom inside the bracket beam 21. One side of each set of connectors 58 is respectively attached to one side of the two sets of reinforcing beams 24, and each set of reinforcing beams 24 has threaded holes on one side for installing multiple sets of connecting bolts 59.

[0067] The reinforcing beam 24 can enhance the overall structural strength of the headrest bracket 2, prevent the headrest bracket 2 from deforming due to bearing foam material, people leaning on it, or emergency pulling, and improve the long-term durability of the headrest bracket 2. The mounting base plate 23 can provide stable support for the foam filling 8, prevent the foam from shifting inside the car headrest 1, and ensure uniform buoyancy distribution. The threaded hole and the connecting bolt 59 are precisely matched to achieve a rigid connection between the storage box 51 and the bracket, further optimizing the mechanical stability of the overall structure.

[0068] Secondly, the upper surface of the mounting base plate 23 is in contact with the lower surface of the foam filler 8, the support beam 21 is U-shaped, and the upper end of the support beam 21 is located inside the foam filler 8. Multiple sets of limiting grooves 22 are opened on both outer sides of the support beam 21.

[0069] The mounting base 23 fits snugly against the lower surface of the foam filler 8, which can limit the movement of the foam within the headrest and prevent the displacement of the foam filler from affecting the buoyancy balance, thus ensuring the floating effect. The U-shaped support beam 21 has high structural strength, which can stably support the weight of the foam and the person, and can also adapt to the internal space of the headrest. Multiple sets of limiting grooves 22 can be directly adapted to the original headrest height adjustment structure of different models (existing technology will not be described in detail), without modifying the car's own design, so as to meet the user's needs for adjusting the head support height without changing the car's structure.

[0070] The lower surface of the mounting base plate 23 is located on the bottom outer side of the car headrest 1, and the lower surface of the mounting base plate 23 is fixedly connected with a first card seat 3 and two sets of second card seats 4. The two sets of second card seats 4 are arranged in parallel, and the first card seat 3 and the two sets of second card seats 4 are arranged in a staggered and perpendicular manner.

[0071] Meanwhile, the first card holder 3 and the second card holder 4 are offset and vertically arranged to facilitate the receiving and storage of the safety hammer 7. Furthermore, a recessed storage cavity is provided between the bottom of the mounting base plate 23 and the car headrest 1. The first card holder 3 and the second card holder 4 are directly installed under the mounting base plate 23, without the need to modify the mounting position of the car seat or car headrest 1, thus simplifying the installation process.

[0072] The safety hammer 7 includes a hammer handle 71 and a protective sleeve 72, which are integrally molded. The protective sleeve 72 is equipped with a conical hammer head 73 for breaking vehicle glass. The hammer handle 71 and the protective sleeve 72 are integrally arranged in a T-shape.

[0073] In a preferred embodiment, the conical hammer head 73 can concentrate the impact force on a local area of ​​the glass, quickly breaking the car window that cannot be opened due to water pressure after the vehicle falls into the water, thus improving the efficiency of breaking the window. At the same time, the T-shaped hammer handle 71 and the protective sleeve 72 are ergonomically designed, making it easy for users to quickly grip and exert force in a tense situation, reducing the window breaking operation time and gaining an advantage for escape.

[0074] Finally, a straight side groove 74 is provided on the outer side of the hammer handle 71, and a seat belt cutter 75 is installed in the side groove 74. The outer side of the hammer handle 71 is provided with anti-slip texture. The seat belt cutter 75 can quickly cut the seat belt that may get stuck after falling into the water, eliminating the obstacle to escape. The anti-slip texture (not shown in the figure) on the outer side of the hammer handle 71 can increase the friction between the hand and the hammer handle 71, so that even when the hand is wet and slippery, it can be held stably, preventing the safety hammer 7 from slipping, ensuring the reliability of window breaking and belt cutting operations, and reducing the risk of operational errors in emergency situations.

[0075] In normal use, the car headrest 1 is used as a regular car headrest 1, relying on part 6 to provide head support comfort, and the pocket can store small items without affecting the original car usage experience;

[0076] When the vehicle falls into the water, the user first removes the car headrest 1 from the car seat (using the original headrest removal structure, no vehicle modification is required), then pulls out the safety restraint strap 54 hidden in the storage box 51 through the buckle 57 (the spring device 52 assists in pulling it out smoothly), and wraps the safety restraint strap 54 around the chest. The two sets of buckles 57 are used to fasten each other, thus completing the wearing of the car headrest 1 on the upper body. The safety restraint strap 54 is equipped with a partial elastic band to ensure that the safety restraint strap 54 is taut on the surface of the human body after it is fully pulled out.

[0077] If the car window cannot be opened, remove the safety hammer 7 from the bottom of the car headrest 1 and use the conical hammer head 73 to concentrate the impact force to break the car window. If the seat belt is stuck, use the cutter in the side groove 74 of the hammer handle 71 to cut the seat belt, and then escape from the vehicle through the car window. The foam filling 8 (such as NBR) in the headrest provides sufficient buoyancy based on Archimedes' principle (total buoyancy ≥ total weight of the person and the headrest) to support the person to float in the water. At the same time, the safety restraint strap 54 prevents the person from separating from the headrest, ultimately helping the person to get out of the water environment and achieve a safe escape.

[0078] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
