Description

Technical Field

[0001] The present invention relates to the technical field of water rescue, and specifically relates to an automatically inflatable life jacket. Background Art

[0002] A life jacket, also known as a life vest, is a life-saving garment that can provide stable buoyancy for a person falling into water and keep the mouth and nose of an unconscious person above the water surface. It is designed to be similar to a vest and is made of nylon fabric, neoprene, buoyancy materials, inflatable materials, reflective materials, etc.

[0003] The prior art also proposes a solution for inflatable life jackets. For example, a Chinese patent application with the publication number CN220391496U discloses a double-airbag and double-air-chamber marine inflatable life jacket, including a life jacket. A plurality of first plastic plates are rotatably connected to the left end of the front side of the life jacket, and a second plastic plate is rotatably connected to the right end of the front side of the life jacket. A plurality of plastic clamping columns are fixedly connected to the right side of the first plastic plate, continuously outputting heat to the wearer. In this way, the problem that the wearer is prone to physical discomfort due to the relatively cold surrounding environment is solved. And when the wearer floats on the sea surface, by opening the gas cylinder, the gas in the gas cylinder enters the inflatable slurry through the hose. In this way, the problem that some people falling into water cannot swim and can only rely on the life jacket to float on the sea surface and cannot move is solved.

[0004] Although the above technical solution solves the problem of the wearer being prone to physical discomfort, there are still other problems in actual use. For example, the triggering method of the gas cylinder in the above content is to be triggered by the wearer himself / herself, and the triggering speed is relatively slow, which is not conducive to the use of the life jacket.

[0005] Therefore, it is necessary to provide an automatically inflatable life jacket to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the inventive concept of the present invention, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0007] The technical solution adopted by the present invention to solve its technical problems is: an automatically inflatable life jacket, including a life jacket body. The life jacket body is integrally formed by shoulder straps and buoyancy members. An inflatable cavity is opened inside the buoyancy member. A compressed gas cylinder is installed inside the buoyancy member. A plugging member is arranged at the open end of the compressed gas cylinder. A firing pin is arranged inside the buoyancy member. The firing pin is used to penetrate the plugging member so that the compressed gas inside the compressed gas cylinder is released and fills the life jacket. An explosive storage cavity is arranged inside the buoyancy member, and gunpowder is stored inside the explosive storage cavity.

[0008] Furthermore, a fixing ring is installed inside the buoyancy member, and the explosive storage chamber is arranged inside the fixing ring; a triggering unit is arranged inside the fixing ring, and the triggering unit is used to control the explosion of the gunpowder inside the explosive storage chamber; during operation, when the user wears the life jacket of the present invention, the explosion of the gunpowder inside the explosive storage chamber is controlled by the triggering unit, so that the impact force generated by the explosion of the gunpowder impacts the firing pin, and thus the firing pin will rush towards the sealing member with a relatively high impact force. Therefore, the sealing member will be separated from the opening of the compressed gas cylinder, achieving the inflation effect of the above-mentioned life jacket. By means of the explosion of gunpowder, the triggering effect is faster and the response efficiency is high.

[0009] Furthermore, the triggering unit includes a rectangular column installed inside the fixing ring. A sensor group is arranged inside the rectangular column. An installation groove adapted to the sensor group is opened inside the rectangular column. A hole groove is opened on the surface of the rectangular column; the sensor group includes a water immersion sensor and a gyroscope angle sensor; during operation, when the user accidentally falls into the water, since the water immersion sensor is arranged inside the rectangular column and the hole groove is opened on its surface, water will enter the surface of the water immersion sensor through the hole groove. When the water immersion sensor contacts water, it will transmit a signal to an external controller, and the controller will immediately control the explosion of the gunpowder inside the explosive storage chamber, achieving the above-mentioned automatic inflation effect.

[0010] Furthermore, a limit ring seat is installed inside the fixing ring. Two limit grooves are opened on the inner wall of the limit ring seat, and the two limit grooves respectively penetrate inside the limit ring seat. A limit arc seat is fixedly installed on the outer side of the firing pin. There are two limit arc seats, and the two limit arc seats are respectively arranged inside the two limit grooves. The end of the limit arc seat is provided with a rounded corner, and the edge of the limit groove is provided with an arc edge. An elastic rod is arranged on the side wall of the limit arc seat, and the end of the elastic rod far away from the limit arc seat is connected to the inner wall of the fixing ring; during operation, during normal use, that is, when the gunpowder inside the explosive storage chamber does not explode; at this time, the limit arc seat is located inside the limit groove, and the elastic rod is in a tightly pressed state; when a dangerous situation occurs and the gunpowder explodes, the impact force generated by the explosion of the gunpowder will drive the firing pin and the limit arc seat away from the limit groove, and the elastic rod will be separated from the tightly pressed state. Therefore, under the action of the elastic rod and the explosion impact force of the gunpowder, it can further accelerate the separation of the sealing member from the compressed gas cylinder, thus facilitating the inflation of the life jacket.

[0011] Furthermore, a limit spring is sleeved on the outer peripheral surface of the elastic rod, and the end of the elastic rod contacts but is not fixedly connected to the limit arc seat.

[0012] Further, the rectangular column is slidably arranged inside the fixed ring, and an unlocking unit is arranged on the outer side of the rectangular column. The unlocking unit is used to disengage the limiting arc seat from the inside of the limiting groove. During operation, the unlocking unit is provided, and the unlocking unit can disengage the limiting arc seat from the inside of the limiting groove, so that the elastic rod and the limiting spring are restored from the tightly pressed state. With such a design, it can avoid the problem that this life jacket is difficult to be used normally when the gunpowder is damp and ineffective.

[0013] Further, the unlocking unit includes an inclined block fixedly installed on the side wall of the rectangular column. A round rod is slidably arranged at the edge of the limiting groove. The end of the round rod contacts the inclined surface of the inclined block. The end of the round rod away from the inclined block contacts the surface of the limiting arc seat. The limiting arc seat is of a telescopic design, and a spring is sleeved on the outer peripheral surface of the telescopic part.

[0014] Further, a rotating disk is rotatably arranged on the outer side of the fixed ring. A groove adapted to the rotating disk is opened inside the fixed ring. An L-shaped handle is installed on the outer peripheral surface of the rotating disk. The L-shaped handle extends out of the outer side of the buoyancy member. Two arc-shaped blocks are installed on the end face of the rotating disk away from the L-shaped handle. The end faces of the two arc-shaped blocks respectively contact the end of the rectangular column. During the rotation of the rotating disk, the two arc-shaped blocks on its end face will contact and press the end of the rectangular column. During operation, when the water immersion sensor and the gyroscope angle sensor are in a warning state exceeding their thresholds, the external controller will control the rotation of the rotating disk. The rotating disk will drive the arc-shaped blocks to rotate. Then, during the rotation of the arc-shaped blocks, they will contact the end of the rectangular column. The rectangular column will drive the inclined block to move and achieve the above effects.

[0015] Further, a deflection frame is rotatably arranged on the outer side of the buoyancy member. A toothed ring is fixedly installed on the outer peripheral surface of the rotating disk. A clamping tooth is arranged at the end of the deflection frame close to the toothed ring. During operation, when the user wears the life jacket normally, the clamping tooth is located between the ratchet teeth on the surface of the toothed ring and limits the toothed ring. With such a design, it can avoid the situation that the rotating disk rotates in a bumpy environment and causes the above operations to be triggered by mistake. When a warning state occurs, the external controller first controls the rotation of the deflection frame to separate the deflection frame and the clamping tooth from the toothed ring, and then the above operations can be continued, which is convenient for the safe use of this life jacket.

[0016] Further, the shape of the clamping tooth is conical, and a rotating shaft adapted to the deflection frame is arranged inside the buoyancy member.

[0017] The beneficial effects of the present invention are as follows: An automatic inflatable life jacket provided by the present invention enables the firing pin of the buoyancy member to move towards one side of the sealing member, causing the sealing member to move away from the opening of the compressed gas cylinder. Subsequently, the compressed gas inside the compressed gas cylinder is released and fills the inflation cavity, causing the life jacket body to gradually expand, thus realizing the function of water rescue. In this way, the compressed gas can be automatically released, and the operation is simple.

[0018] The impact force generated by the explosion of gunpowder drives the firing pin and the limiting arc seat away from the limiting groove, and the elastic rod disengages from the tightly pressed state. Therefore, under the action of the elastic rod and the explosion impact force of the gunpowder, the sealing member can be further accelerated to disengage from the compressed gas cylinder, thus facilitating the inflation of the life jacket.

[0019] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The following will refer to the drawings for a further detailed description of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 5 shown, the present invention provides an automatically inflatable life jacket, including a life jacket body 1. The life jacket body 1 is integrally formed by a shoulder strap 101 and a buoyancy member 102. An inflatable chamber 2 is opened inside the buoyancy member 102. A compressed gas cylinder 3 is installed inside the buoyancy member 102. A plugging member 4 is arranged at the opening end of the compressed gas cylinder 3. An explosive storage chamber 7 is arranged inside the buoyancy member 102. Gunpowder is stored inside the explosive storage chamber 7. A firing pin 5 is arranged inside the buoyancy member 102. The firing pin 5 is used to penetrate the plugging member 4 so that the compressed gas inside the compressed gas cylinder 3 is released and fills the life jacket. The inflatable life jacket needs to be inflated to achieve the life-saving function. When using the life jacket of the embodiment of the present invention, in the initial state, the plugging member 4 is located at the opening inside the compressed gas cylinder 3 and plugs the compressed gas cylinder 3. When the user puts on the life jacket body 1 of the embodiment of the present invention and falls into the water, at this time, the explosive in the explosive storage chamber 7 inside the buoyancy member 102 will explode. The impact force generated by the explosion will cause the firing pin 5 to rush towards one side of the plugging member 4, so that the plugging member 4 moves away from the opening of the compressed gas cylinder 3. Then, the compressed gas inside the compressed gas cylinder 3 will be released and filled inside the inflatable chamber 2, so that the life jacket body 1 gradually expands to realize the function of water rescue. In this way, the compressed gas can be automatically released, and the operation is simple.

[0025] It should be noted that the explosive force generated by the gunpowder in the explosive storage chamber 7 will not damage the life jacket or harm the personnel on the water.

[0026] A fixing ring 6 is installed inside the buoyancy member 102, and the explosive storage chamber 7 is arranged inside the fixing ring 6; a triggering unit is arranged inside the fixing ring 6, and the triggering unit is used to control the explosion of the gunpowder inside the explosive storage chamber 7; during operation, when the user puts on the life jacket of the present invention, the explosion of the gunpowder inside the explosive storage chamber 7 is controlled by the triggering unit, so that the impact force generated by the explosion of the gunpowder impacts the firing pin 5, and thus the firing pin 5 will rush towards the sealing member 4 with a relatively high impact force. Therefore, the sealing member 4 will be separated from the opening of the compressed gas cylinder 3, realizing the inflation effect of the above-mentioned life jacket. By means of the explosion of gunpowder, the triggering effect is faster and the response efficiency is high.

[0027] The triggering unit includes a rectangular column 601 installed inside the fixing ring 6. A sensor group 8 is arranged inside the rectangular column 601. An installation groove adapted to the sensor group 8 is opened inside the rectangular column 601, and a hole groove is opened on the surface of the rectangular column 601; the sensor group 8 includes a water immersion sensor; during operation, when the user accidentally falls into the water, since the water immersion sensor is arranged inside the rectangular column 601 and the hole groove is opened on its surface, water will enter the surface of the water immersion sensor through the hole groove. When the water immersion sensor contacts water, it will transmit a signal to an external controller, and the controller will immediately control the explosion of the gunpowder inside the explosive storage chamber 7 to realize the above-mentioned automatic inflation effect; It should be noted that the water immersion sensor can set its own alarm threshold to achieve the effect of automatic signal transmission. For example, when the height at which the probe of the water immersion sensor contacts water is greater than 2 mm, the effect of automatic signal transmission and alarm can be achieved in this case.

[0028] Such as Figures 2 to 7As shown, a limit ring seat 602 is installed inside the fixed ring 6. Two groups of limit grooves 9 are formed in the inner wall of the limit ring seat 602. The two groups of limit grooves 9 penetrate through the inside of the limit ring seat 602 respectively. A limit arc seat 10 is fixedly installed on the outer side of the firing pin 5. There are two limit arc seats 10, and the two limit arc seats 10 are respectively arranged inside the two groups of limit grooves 9. The end of the limit arc seat 10 is provided with a rounded corner, and the edge of the limit groove 9 is provided with an arc edge. An elastic rod 11 is arranged on the side wall of the limit arc seat 10. The end of the elastic rod 11 far away from the limit arc seat 10 is connected to the inner wall of the fixed ring 6. During operation, when in normal use, that is, when the gunpowder in the explosive storage cavity 7 does not explode; at this time, the limit arc seat 10 is located inside the limit groove 9, and the elastic rod 11 is in a tightly pressed state; when a dangerous situation occurs and the gunpowder explodes, the impact force generated by the explosion of the gunpowder will drive the firing pin 5 and the limit arc seat 10 away from the limit groove 9, and the elastic rod 11 will be disengaged from the tightly pressed state. Therefore, under the action of the elastic rod 11 and the explosion impact force of the gunpowder, it can further accelerate the detachment of the plugging member 4 from the compressed gas cylinder 3, thus facilitating the inflation of the life jacket.

[0029] A limit spring 12 is sleeved on the outer peripheral surface of the elastic rod 11. The end of the elastic rod 11 contacts but is not fixedly connected to the limit arc seat 10. During operation, since the end of the elastic rod 11 contacts but is not fixedly connected to the limit arc seat 10, when the elastic rod 11 and the limit spring 12 on its surface recover from the tightly pressed state, the elastic rod 11 will not move close to the plugging member 4 together with the firing pin 5, and it is beneficial for the elastic rod 11 to squeeze the limit arc seat 10, so that the firing pin 5 contacts the plugging member 4.

[0030] As Figures 4 to 9 shown, the rectangular column 601 is slidably arranged inside the fixed ring 6. An unlocking unit is arranged on the outer side of the rectangular column 601. The unlocking unit is used to control the limit arc seat 10 to disengage from the limit groove 9. During operation, the unlocking unit drives the limit arc seat 10 to disengage from the limit groove 9, so that the elastic rod 11 and the limit spring 12 recover from the tightly pressed state. With such a design, it can avoid the problem that the life jacket is difficult to be used normally when the gunpowder is damp and fails.

[0031] The unlocking unit includes an oblique block 603, which is fixedly mounted on the side wall of the rectangular column 601. A round rod 901 is slidably arranged at the edge of the limiting groove 9. The end of the round rod 901 contacts the inclined surface of the oblique block 603, and the end of the round rod 901 away from the oblique block 603 contacts the surface of the limiting arc seat 10. The limiting arc seat 10 is a telescopic design, and a spring is sleeved on the outer peripheral surface of the telescopic part. When working, in the initial state, that is, when the limiting arc seat 10 is located inside the limiting groove 9, the end of the round rod 901 contacts the side wall of the limiting arc seat 10. When the water immersion sensor and the gyroscope angle sensor exceed the warning state of their threshold values, the unlocking unit will control the rectangular column 601 to move, so that the rectangular column 601 drives the inclined block 603 to move, and the inclined surface of the inclined block 603 squeezes the end of the round rod 901. Since the limit arc seat 10 is a telescopic design, the limit arc seat 10 will be separated from the limit groove 9 under the squeezing of the round rod 901, and the elastic rod 11 and the limit spring 12 will recover from the compressed state, and under the elastic force of the limit spring 12 and the elastic rod 11, the striker 5 can be quickly driven to contact the blocking member 4. Such a design can push out the firing pin 5 in combination with the gunpowder explosion, and can further prevent the firing pin 5 from hitting the blocking member 4 when the gunpowder is damp, thereby providing a certain mechanical insurance effect; it should be noted that under the elastic force of the limit spring 12 and the elastic rod 11, its restoring force can drive the firing pin 5 to hit the blocking member 4, and the blocking member 4 will be separated from the compressed gas cylinder 3.

[0032] like Figures 5 to 9 As shown, a rotating disk 13 is rotatably provided on the outer side of the fixing ring 6, and a groove matching the rotating disk 13 is opened inside the fixing ring 6. An L-shaped handle 14 is installed on the outer peripheral surface of the rotating disk 13, and the L-shaped handle 14 extends out of the outer side of the buoyancy member 102. Two groups of arc blocks 15 are installed on the end face of the rotating disk 13 away from the L-shaped handle 14, and the end faces of the two groups of the arc blocks 15 are respectively in contact with the end parts of the rectangular column 601. When the rotating disk 13 rotates, the two groups of arc blocks 15 on its end face will contact and squeeze the end part of the rectangular column 601. When working, when the water immersion sensor and the gyroscope angle sensor exceed the warning state of their threshold values, the rotating disk 13 will be controlled to rotate by an external controller, and the rotating disk 13 will drive the arc blocks 15 to rotate. After that, when the arc blocks 15 rotate, they will contact the end part of the rectangular column 601, and the rectangular column 601 will drive the oblique blocks 603 to move, and the above-mentioned effects will be achieved.

[0033] A deflection frame 16 is rotatably arranged on the outer side of the buoyancy member 102. A toothed ring 17 is fixedly installed on the outer peripheral surface of the rotating disk 13. A locking tooth 18 is arranged at the end of the deflection frame 16 close to the toothed ring 17. During operation, when the user wears the life jacket properly, the locking tooth 18 is located between the ratchet teeth on the surface of the toothed ring 17 and limits the toothed ring 17. The shape of the locking tooth 18 is conical. A rotating shaft adapted to the deflection frame 16 is arranged inside the buoyancy member 102. With such a design, it can be avoided that the rotating disk 13 rotates in a bumpy environment, resulting in the mis-triggering of the above operations. When a warning state occurs, the deflection frame 16 is first controlled to rotate by an external controller, so that the deflection frame 16 and the locking tooth 18 are separated from the toothed ring 17, and then the above operations can be continued, which is convenient for the safe use of this life jacket.

[0034] Working principle: The inflatable life jacket needs to be inflated to achieve the life-saving effect. When the life jacket of the embodiment of the present invention needs to be used, in the initial state, the blocking member 4 is located at the opening inside the compressed gas cylinder 3 and blocks the compressed gas cylinder 3. When the user puts on the life jacket body 1 of the embodiment of the present invention and falls into the water, at this time, the striker 5 located on the buoyancy member 102 will move towards one side of the blocking member 4, so that the blocking member 4 moves away from the opening of the compressed gas cylinder 3. Then, the compressed gas inside the compressed gas cylinder 3 will be released and filled into the inflation cavity 2, so that the life jacket body 1 gradually expands, realizing the function of water rescue. In this way, the compressed gas can be automatically released, and the operation is simple. When the user accidentally falls into the water, since a water immersion sensor is arranged inside the rectangular column 601 and holes are provided on its surface, water will enter the surface of the water immersion sensor through the holes. When the water immersion sensor contacts water, it will transmit a signal to the external controller, and the controller will immediately control the gunpowder inside the explosive storage cavity 7 to explode, realizing the above-mentioned automatic inflation effect. During normal use, that is, when the gunpowder inside the explosive storage cavity 7 does not explode; at this time, the limiting arc seat 10 is located inside the limiting groove 9, and the elastic rod 11 is in a tightly pressed state. When a dangerous situation occurs and the gunpowder explodes, the impact force generated by the explosion of the gunpowder will drive the striker 5 and the limiting arc seat 10 away from the limiting groove 9, and the elastic rod 11 will be disengaged from the tightly pressed state. Therefore, under the action of the elastic rod 11 and the explosion impact force of the gunpowder, it can further accelerate the separation of the blocking member 4 from the compressed gas cylinder 3, facilitating the inflation of the life jacket. In the initial state, that is, when the limit arc seat 10 is located inside the limit groove 9, the end of the round rod 901 is in contact with the side wall of the limit arc seat 10; when the water immersion sensor exceeds the warning state of its threshold, under the action of the unlocking unit, the rectangular column 601 will be controlled to move, so that the rectangular column 601 drives the inclined block 603 to move, and the inclined surface of the inclined block 603 will squeeze the end of the round rod 901. Since the limit arc seat 10 is a telescopic design, under the squeezing of the round rod 901, the limit arc seat 10 will be separated from the limit groove 9, and the elastic rod 11 and the limit spring 12 will recover from the compressed state, and under the elastic force of the limit spring 12 and the elastic rod 11, the striker 5 can be quickly driven to contact the blocking member 4; Such a design can push out the firing pin 5 in combination with the gunpowder explosion, and further can prevent the firing pin 5 from hitting the blocking member 4 when the gunpowder is damp, thereby providing a certain mechanical insurance effect; it should be noted that under the elastic force of the limit spring 12 and the elastic rod 11, its restoring force can drive the firing pin 5 to hit the blocking member 4, and the blocking member 4 will be separated from the compressed gas cylinder 3; when the water immersion sensor and the gyroscope angle sensor exceed the warning state of their threshold values, the rotating disk 13 will be controlled to rotate through the external controller, and the rotating disk 13 will drive the arc block 15 to rotate, and then the arc block 15 will contact the end of the rectangular column 601 during the rotation process, and the rectangular column 601 will drive the inclined block 603 to move, and the above-mentioned effect will be achieved.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
