Description

Technical Field

[0001] The present invention relates to an anti-overturning system, and particularly to an anti-overturning airbag system for armored vehicles. Background Art

[0002] Armored vehicles are very important means of transportation in military operations and are often used in various complex environmental conditions, including rugged terrain environments, harsh weather environments, etc. During actual driving, armored vehicles are prone to sinking and overturning. For example, when an armored vehicle is driving on a narrow mountain road, the wheels drive out of the road, resulting in the overturning of the armored vehicle and it cannot continue to drive. Or when driving on complex and rugged terrain, the wheels sink into a mud pit on the ground, causing the tires to slip and unable to drive out, etc.

[0003] Currently, there is little research on how armored vehicles can resume normal driving in these situations, and there is a lack of an effective anti-overturning system for armored vehicles. In related fields, some scholars have proposed to set up inflatable auxiliary tires on one side of the tire. When the vehicle has a flat tire, the auxiliary tire can be inflated to jack up and temporarily act as a tire to ensure the stability of the vehicle. However, this method is not very effective when the wheels of an armored vehicle overturn, because the auxiliary tire may sink together with the vehicle tire, and its main function is to act as a tire after inflation and cannot solve the overturning problem of armored vehicles. Therefore, it is necessary to design an effective anti-overturning system. Summary of the Invention

[0004] To solve the above problems, the present invention provides an anti-overturning airbag system for armored vehicles, which can adapt to various terrains during use, can jack up the armored vehicle to restore it to a stable state, so that the armored vehicle can continue to drive, effectively solving the driving problem caused by the overturning of the armored vehicle. And the entire system is automated, and the driver can operate it in the cockpit without too much manual participation.

[0037] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0038] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0039] As Figure 1 As shown, the present invention provides an anti-overturn airbag system for armored vehicles. This system can, when the armored vehicle overturns or rolls over, support the vehicle by inflating the airbag 103 to restore it to a horizontal state and ensure that the vehicle can continue to drive. The design of this system fully considers the stability problems of armored vehicles under extreme conditions such as complex terrains, high-speed turning, and explosion shocks, and combines the coordinated actions of the airbag 103, support structure, starting device 12, and limiting device 7 to achieve automatic deployment and recovery, improving the survivability and sustainable combat ability of armored vehicles.

[0040] The system mainly includes a chassis connecting plate 2, multiple support pieces 1, a main support 6, a first telescopic rod 9, a second telescopic rod 8, a sleeve rod 4, a corrugated pipe 5, an airbag device 10, a starting device 12, a limiting device 7 and an automatic exhaust device 104. The chassis connecting plate 2 is fixedly connected to the armored vehicle chassis by bolts and is connected and conducted with the air supply system of the armored vehicle, and is used to convey compressed gas to the airbag device 10. Multiple support pieces 1 are provided at the bottom of the chassis connecting plate 2. One end of the support piece 1 is rotatably connected to the main support 6 through a main shaft 11, and the other end is rotatably connected to the sleeve rod 4 through a pin shaft, forming a movable support structure to adapt to the unfolding requirements at different angles. The second telescopic rod 8 is sleeved inside the sleeve rod 4, and the first telescopic rod 9 is sleeved inside the main support 6. The bottom of the first telescopic rod 9 is hinged to the free end of the second telescopic rod 8. The movement of the telescopic rods can control the angle and position of the airbag device 10, so that the system can stably support the armored vehicle when unfolding, as Figure 2 and Figure 3 shown.

[0041] The airbag device 10 is used to lift the armored vehicle by inflating to restore its horizontal state. The device is arranged at the bottom of the first telescopic rod 9 and is connected and conducted with the air supply system of the armored vehicle through a gas guiding mechanism. The gas guiding mechanism includes a corrugated pipe 5. One end of the corrugated pipe 5 is connected to the first air inlet interface 3 on the chassis connecting plate 2, and the other end is connected to the second air inlet interface on the main support 6. 13 The main support 6 and the first telescopic rod 9 are both provided with gas guiding pipes 14 evenly distributed inside. One end of the gas guiding pipe 14 is connected and conducted with the corrugated pipe 5, and the other end is connected and conducted with the airbag device 10, ensuring that the gas can smoothly enter the airbag 103, so as to achieve rapid inflation, as Figure 4 and Figure 5 shown.

[0042] As Figure 8 and Figure 9As shown, the airbag device 10 includes an airbag box 106, an airbag 103, a bottom cover 102, a third motor 110, a gear drive set, and a wire winding assembly. The airbag box 106 is fixedly installed on the top of the airbag 103, and the bottom of the airbag 103 is provided with a bottom cover 102. The wire winding assembly includes a rotating shaft 108, a wire winding wheel 107, and a rope 101. One end of the rope 101 is wound around the wire winding wheel 107, and the other end is fixedly connected to the bottom cover 102 of the airbag. The third motor 110 is fixedly installed in the airbag box 106, and its output end is connected to the gear drive set. The gear drive set includes a second driving gear 111 and a second driven gear 109. The second driving gear 111 is installed on the output end of the third motor 110, and the second driven gear 109 is installed on the rotating shaft 108, and the two are meshed and connected. When the system is in a vertical state, the third motor 110 drives the gear set to rotate, drives the wire winding wheel 107 to release the rope 101, and makes the bottom cover 102 descend, thereby deploying the airbag 103. The airbag 103 is filled with high-pressure gas through an air duct 14 to generate a jacking force to lift the armored vehicle. The bottom of the airbag box 106 is provided with a third air inlet interface 105, which is connected and communicated with the air guiding mechanism to ensure the smoothness of the inflation channel.

[0043] As Figure 6 shown, the starting device 12 is used to drive the main support 6 to rotate, so that the system rotates from a horizontal state to a vertical state and returns to the horizontal state after use. The starting device 12 is fixedly installed on one side of the support piece 1 and includes a first motor 14 and a gear set. The gear set is composed of a first driving gear 16 and a first driven gear 15. The first driven gear 15 is fixedly installed on the main shaft 11, and the first motor 14 is fixedly installed on the support piece 1, and its output end is installed with a first driving gear 16. When the first motor 14 is started, the first driving gear 16 drives the first driven gear 15 and the main shaft 11 to rotate, thereby driving the main support 6 to rotate relative to the support piece 1 to realize the deployment or retraction of the entire system.

[0044] As Figure 7As shown in the figure, the limiting device 7 is used to limit and support the main support 6 when the system is in the vertical state to prevent it from rotating and failing. This device is installed at the rotating position of the main support 6 and the support piece 1, and includes a second motor 75, a first limiting member 72, a second limiting member 77, a latch rod 71, a rack 76 and a driving gear. The first limiting member 72 is fixedly installed on the support piece 1 and is arranged opposite to the latch rod 71. The second limiting member 77 is fixedly installed on the main support 6. The latch rod 71 passes through the second limiting member 77, and its bottom is fixed on the upper end surface of the rack 76. The latch rod 71 moves with the rack 76 to realize the insertion or withdrawal of the latch rod 71. The second motor 75 is fixedly installed on the main support 6 on one side of the rack 76, and its output end is equipped with a driving gear, which meshes with the rack 76. When the system enters the vertical state, the second motor 75 starts, drives the driving gear to rotate, makes the rack 76 move forward, and pushes the latch rod 71 to insert into the first limiting member 72, thereby limiting and fixing the main support 6 to ensure that the system will not fail due to force. When the system work is over, the second motor 75 rotates in the reverse direction to make the latch rod 71 withdraw from the limiting member. At this time, the main support 6 can rotate freely, and the system can be retracted to the flat state. In order to further improve the reliability of the limiting device 7, a limiting baffle 78 is provided on the main support 6 on the side far from the second limiting member 77 to prevent the latch rod 71 from moving excessively or loosening due to vibration.

[0045] The automatic exhaust device 104 of the system is used to control the exhaust of the airbag 103 so that it can be retracted to the original state after the system work is over. This device is arranged on the top of the airbag box 106 and is provided with an exhaust outlet and an exhaust inlet, and the exhaust inlet is communicated with the airbag 103. As Figure 10 and Figure 11 shown, the automatic exhaust device 104 includes a device shell. An exhaust passage 1041 is provided inside the device shell. A spring 1043 is arranged in the exhaust passage 1041. A valve core 1044 is arranged on one side of the spring 1043. The valve core 1044 is used to seal the exhaust passage 1041. An electromagnet 1042 is arranged on the other side of the spring 1043. The valve core 1044 is made of metal material. When the electromagnet 1042 is energized, the valve core 1044 is adsorbed and compresses the spring 1043, so that the exhaust passage 1041 is opened, and the gas inside the airbag 103 is discharged. After the electromagnet 1042 is powered off, the spring 1043 rebounds and pushes the valve core 1044 to close the exhaust passage 1041 to prevent the airbag 103 from deflating. When the system is retracted, the automatic exhaust device 104 starts to release the gas inside the airbag 103. At the same time, the third motor 110 drives the winding wheel 107 to rotate in the reverse direction to retract the rope 101, so that the bottom cover 102 compresses the airbag 103 until it is completely received. Then the exhaust device is closed to complete the system reset.

[0046] The armored vehicle anti-rollover airbag 103 system of the present invention can adapt to various terrains, and can be quickly deployed when the armored vehicle overturns or becomes unstable. The airbag 103 is inflated to lift the vehicle, so that the armored vehicle returns to a horizontal state and can continue to travel. The system realizes automatic control, and the driver can operate directly in the cockpit without additional manual intervention, which improves the convenience of using the system. At the same time, the airbag 103 can be automatically recovered after deployment to achieve recycling, and does not need to be replaced after use like a car airbag, which greatly improves the working efficiency and durability of the system.

[0047] The specific working process is as follows:

[0048] First, the starting device 12 is started, and the first motor 14 and the gear set drive the main shaft 11 to rotate, so that the main support 6 rotates to a vertical state and stops. Then, the limiting device 7 is started, and the second motor 75 drives the driving gear to drive the rack 76 to move, so that the latch rod 71 moves forward and inserts into the first limiting member 72 until it stops moving. At this time, the entire system remains in a vertical state.

[0049] Next, the airbag device 10 starts to start, and the third motor 110 drives the gear drive group to drive the rotating shaft 108 to rotate, so that the winding wheel 107 lowers the rope 101, and the airbag 103 is unfolded from the compressed and folded state. At the same time, the air supply system of the armored vehicle starts to supply air, and the gas enters the airbag 103 through the bellows 5 and the air guide tube 14. The airbag 103 is gradually inflated and unfolded, and the internal pressure of the airbag 103 gradually increases, lifting the armored vehicle. When the armored vehicle returns to a horizontal state from a tilted state, the sunken tire is separated from the ground at the sunken place, and no longer affects the forward movement of the armored vehicle due to jamming or slipping, the inflation process of the airbag 103 stops, and this process can be controlled by the inflation valve in the cab.

[0050] When the armored vehicle leaves the fallen area, the automatic exhaust device 104 is activated to release the gas inside the airbag 103. At the same time, the third motor 110 drives the rotating shaft 108 to drive the winding wheel 107 to rotate in the opposite direction to retract the rope 101. During the retraction process, the bottom cover 102 of the airbag compresses the airbag 103 under the action of the rising pressure, so that the gas inside the airbag 103 is discharged until the bottom cover 102 of the airbag is completely closed, and the airbag 103 is stored.

[0051] Then, the limiting device 7 is started again, and the second motor 75 drives the driving gear to drive the rack 76 to move, so that the latch rod 71 moves backward, exits the first limiting member 72, and releases the limiting effect on the main support 6. Finally, the first motor 14 of the starting device 12 is started, and the driving gear group drives the main shaft 11 to rotate in the opposite direction, so that the main support 6 is restored from the vertical state to the horizontal state. At this point, the entire system completes a working cycle and enters the standby state, ready for the next use.

[0052] During the entire working process, the system can operate fully automatically without manual intervention, greatly improving the self-recovery ability of the armored vehicle in the event of overturning or sinking, reducing manual operations, and improving driving safety and convenience. In addition, the system can be recycled, avoiding the disadvantage of needing to replace the traditional disposable airbag 103, and has high economic value.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
