DETAILED DESCRIPTION

[0044] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components are denoted by the same or similar reference numerals throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0045] In the description of the present application, the terms "first", "second" are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] The following will be described in detail below Figures 1-11 The container assembly 100 according to embodiments of the present application and the vehicle 1000 having the same are described in detail below.

[0047] Referring to Figures 1-10 As shown, the pressure relief device according to embodiments of the present application can include a mounting seat 6 and a pressure relief structure 130, the mounting seat 6 having a seat body passage 7, the seat body passage 7 having a pressure relief port 73, the pressure relief structure 130 including a movable piece 12, the movable piece 12 being adapted to block or open the pressure relief port 73, the movable piece 12 being selectively lockable in a locking position blocking the pressure relief port 73.

[0048] The pressure relief device is adapted to be connected to the storage capsule 3, the storage capsule 3 having a storage cavity 33 therein, the seat body passage 7 being communicable with the storage cavity 33. Specifically, the seat body passage 7 has a first interface, the first interface being communicable with the storage cavity 33. The medium in the seat body passage 7 can enter the storage cavity 33 through the first interface, and the medium in the storage cavity 33 can enter the seat body passage 7 through the first interface.

[0049] It should be noted that the medium can be in various forms, for example, the medium can be a gas or a liquid or a gas-liquid mixture, etc.

[0050] The movable element 12 is used for pressure relief of the storage bag 3, and the pressure relief specifically refers to flowing at least part of the medium in the storage bag 3 out of the pressure relief port 73 to reduce the amount of medium in the storage bag 3. For example, when the medium is a gas, the movable element 12 is used for pressure relief of the storage bag 3. For example, when the medium is a liquid, the movable element 12 is used for pressure relief of the storage bag 3.

[0051] During the process of introducing the medium into the storage bag 3 or the reaction force of the storage bag 3 under external pressure, an action force is easily applied to the movable element 12, which tends to make the movable element 12 retreat, that is, the action force tends to make the movable element 12 move in the direction of opening the pressure relief port 73, specifically, the action force tends to make the movable element 12 move in the direction of F3. By locking the movable element 12 in the locking position, the movable element 12 can be locked in the locking position, so that the movable element 12 blocks the pressure relief port 73, thereby effectively preventing the phenomenon of gas leakage caused by the retreat of the movable element 12.

[0052] Optionally, the movable element 12 can be configured as a pin, a shaft or the like structure, which is simple in structure and convenient to process and manufacture.

[0053] According to the pressure relief device of the embodiments of the present application, by locking the movable element 12 in the locking position, the movable element 12 can reliably block the pressure relief port 73, and the movable element 12 is prevented from being randomly moved, thereby avoiding the pressure relief of the pressure relief device in a non-working state, avoiding the leakage of the storage bag 3, and avoiding the abnormal leakage of the storage bag 3 caused by the retreat of the movable element 12, and improving the safety, stability and reliability of the pressure relief device.

[0054] In some embodiments of the present application, referring to Figures 1-4 As shown in the figure, the seat body channel 7 includes a first channel segment 71, the pressure relief port 73 is arranged on the first channel segment 71, the first channel segment 71 extends along a first direction, the movable element 12 is adapted to reciprocate in a second direction, the second direction is different from the first direction, and when the movable element 12 is in the locking position, the movable element 12 blocks the first channel segment 71 to lock the movable element 12 in the locking position. As shown in the figure, Figures 1-2 As shown in the figure, when the movable element 12 is in the locking position, after the movable element 12 blocks the first channel segment 71, the medium no longer impacts the axial end of the movable element 12, but acts on the peripheral wall of the movable element 12. By changing the force direction of the movable element 12, the axial end force is effectively changed into non-axial force, which can ensure that the movable element 12 does not retreat, exit the seat body channel 7, and the medium leaks through the pressure relief port 73 due to the back pressure of the medium, and avoids the abnormal leakage of the storage bag 3 caused by the retreat of the movable element 12.

[0055] For example, the first direction is the F1-F2 direction in Figure 1 , Figure 3 , and the second direction is the F3-F4 direction in Figure 1 , Figure 3 .

[0056] In combination with Figure 2 and Figure 4 , the channel wall of the seat channel 7 is further provided with a groove 75, specifically, the channel wall of the first channel segment 71 is provided with the groove 75, when the movable element 12 is in the locked position, one end of the movable element 12 located in the first channel segment 71 extends into the groove 75, specifically, the F4 end of the movable element 12 extends into the groove 75, in this way, the medium in the seat channel 7 will not contact the F4 end of the movable element 12, and the F3 end of the movable element 12 is located outside the seat channel 7, the medium in the seat channel 7 will also not contact the F3 end of the movable element 12, and the medium in the seat channel 7 will only contact the outer peripheral wall of the movable element 12. The recoil force of the medium will not cause the movable element 12 to move along F3, therefore, the movable element 12 can tightly block the pressure relief port 73, and the abnormal leakage of the storage bag 3 caused by the retreat of the movable element 12 is avoided.

[0057] If the axial end face of the movable element 12 directly contacts the medium in the seat channel 7, the movable element 12 is subjected to an axial force, when the pressure or the recoil force of the medium in the seat channel 7 is greater than the pre-tightening force of the movable element 12 (for example, the pre-tightening force of the second sealing structure 14 and the third sealing structure 18 on the movable element 12), the movable element 12 retreats along the F3 direction, and the seat channel 7 leaks air, which will cause the storage bag 3 to fail to function, when the storage bag 3 is a floating water bag and is applied to the vehicle 1000, the failure of the storage bag 3 to function will cause the vehicle 1000 to sink, which will cause loss of the people on the vehicle and the property of the vehicle. Therefore, the axial end face of the movable element 12 is isolated from the medium in the seat channel 7, so that the movable element 12 will not retreat along the F3 direction, which well solves the leakage risk of the storage bag 3, when the storage bag 3 is a floating water bag and is applied to the vehicle 1000, the buoyancy force received by the vehicle 1000 is large, and the vehicle 1000 will not sink, which ensures the safety of the people on the vehicle and the property of the vehicle 1000.

[0058] In some embodiments of the present application, the angle between the second direction and the first direction is not less than 45°. For example, the angle between the second direction and the first direction can be 45°, 60°, 75°, 90°, etc., and can also be other angle values not less than 45°, which are not listed one by one here. By setting the angle between the second direction and the first direction to be not less than 45°, the impact force direction of the medium on the movable element 12 can be far away from the axial direction of the movable element 12, the component of the impact force on the axial direction of the movable element 12 is small after the impact force acts on the movable element 12, the movable element 12 is not easy to retreat, and the movable element 12 is not easy to be pushed out of the seat channel 7.

[0059] In some embodiments of the present application, the second direction is perpendicular to the first direction. In other words, the included angle between the second direction and the first direction is 90°. In this way, the axial end of the movable member 12 is subjected to a radial force, and the impact force of the medium on the movable member 12 in the axial direction of the movable member 12 is minimized, so that the phenomenon of the movable member 12 retreating, exiting the seat body passage 7, and the medium leaking through the pressure relief opening 73 due to the back pressure of the medium can be avoided.

[0060] In some embodiments of the present application, the movable member 12 is a metal member, so that the strength of the movable member 12 is higher and can withstand a larger impact force. By lengthening the movable member 12, the axial end face of the movable member 12 is not subjected to a force, and is changed to a radial force of the movable member 12. Since the movable member 12 is a metal member, the radial direction of the movable member 12 can withstand a pressure in the seat body passage 7 that is much larger than the pressure without breaking, and at the same time, the movable member 12 is more secure due to the radial force exerted by the medium on the movable member 12, and does not retreat in the F3 direction. Thus, the risk of leakage of the storage bag 3 is well solved, and when the storage bag 3 is used as a floating air bag and applied to the vehicle 1000, the safety of the personnel on the vehicle and the vehicle 1000 is maximized.

[0061] When the storage bag 3 is used as a floating air bag and applied to the vehicle 1000, the movement of the movable member 12 in the second direction is controlled by the control system of the vehicle 1000. As shown in Figures 3-4 When the vehicle 1000 has a need to land, the control system of the vehicle 1000 sends a signal to control the movable member 12 to retract in the F3 direction. When the movable member 12 is in the retracted state, the pressure relief opening 73 is in communication with the pressure relief hole 15, and the gas in the storage bag 3 is discharged from the pressure relief hole 15 under the action of water pressure.

[0062] In some embodiments of the present application, the movable member 12 is a plastic member, which has a lower cost and a lighter weight.

[0063] In some embodiments of the present application, as shown in Figures 1-4 The seat body passage 7 further includes a second passage segment 72, which is in communication with the first passage segment 71, so that the pressure relief structure 130 and the storage bag 3 can be arranged at a reasonable position, for example, the pressure relief structure 130 can be arranged away from the storage bag 3, and the arrangement flexibility of the pressure relief structure 130 and the storage bag 3 is improved.

[0064] In some embodiments of the present application, as shown in Figures 1-4 The second passage segment 72 and the first passage segment 71 can extend in different directions, for example, the first passage segment 71 extends in the first direction, and the second passage segment 72 can extend in the second direction, so as to further improve the arrangement flexibility of the pressure relief structure 130 and the storage bag 3.

[0065] In some embodiments of the present application, one end of the first channel segment 71 away from the second channel segment 72 is a closed end.

[0066] In some embodiments of the present application, referring to Figures 1-4 As shown in the figure, one end of the first channel segment 71 away from the second channel segment 72 is provided with a plug 11, which is used to block the outlet of the first channel segment 71 at the position of the plug 11 to prevent the medium from leaking from the position of the plug 11.

[0067] In some embodiments of the present application, referring to Figures 5-10 As shown in the figure, the pressure relief device further comprises a limiting structure 170, which is installed on the mounting seat 6 and / or the pressure relief structure 130, and is used to selectively lock the movable piece 12 in the locked position. Specifically, the limiting structure 170 can be installed only on the mounting seat 6, only on the pressure relief structure 130, or on both the mounting seat 6 and the pressure relief structure 130. When the limiting structure 170 locks the movable piece 12 in the locked position, the movable piece 12 blocks the pressure relief port 73, and the medium in the seat body channel 7 will not leak through the pressure relief port 73.

[0068] In some embodiments of the present application, the limiting structure 170 comprises a limiting piece 16, which is arranged on the mounting seat 6 and / or the pressure relief structure 130, and is used to selectively lock the movable piece 12 in the locked position. For example, the storage bag 3 is a floating air bag, and the limiting piece 16 is used to prevent the movable piece 12 from retreating and leaking air under pressure during and after the storage bag 3 is inflated. When the storage bag 3 does not need to be relieved, the limiting piece 16 locks the movable piece 12 in the locked position, as shown in the figure, the movable piece 12 is in the locked position, and the movable piece 12 can reliably block the pressure relief port 73, which can ensure that the movable piece 12 will not retreat due to the back pressure of the medium, avoiding the abnormal leakage of the storage bag 3 due to the retreat of the movable piece 12; when the storage bag 3 needs to be relieved, the limiting piece 16 does not lock the movable piece 12, and the movable piece 12 is movable to open the pressure relief port 73. Figures 5-6

[0069] Alternatively, the limiting piece 16 can be configured as a pin, shaft or other structure, which is simple in structure and easy to manufacture.

[0070] In some embodiments of the present application, referring to Figures 5-10 ​As shown, the movable member 12 is adapted to reciprocate in a second direction, and the limiting member 16 is adapted to move towards or away from the movable member 12 in a third direction to selectively lock the movable member 12 in the locked position, the second direction being different from the third direction. The second direction is the axial direction of the movable member 12, and the limiting member 16 is adapted to reciprocate in the third direction to move towards or away from the movable member 12. By arranging the limiting member 16 to move in the third direction, the movable member 12 can be non-axially limited, and it can be ensured that the movable member 12 will not retreat and the medium will not leak through the pressure relief port 73 due to the back pressure of the medium.

[0071] For example, the third direction is the F5-F6 direction in Figure 5 , Figure 7 , Figure 9 , and the second direction is the F3-F4 direction in Figure 5 , Figure 7 , Figure 9 .

[0072] Referring to Figures 5-6 , when the storage capsule 3 does not need to be pressure relieved, the movable member 12 is first moved in the F4 direction to block the pressure relief port 73, and then the limiting member 16 is moved in the F6 direction to move towards the movable member 12, thereby locking the position of the movable member 12. In this way, even if the medium in the storage chamber 33 can enter the seat passage 7, the medium in the seat passage 7 cannot flow out through the pressure relief port 73. Figures 7-8 Referring to Figures 9-10 , when the storage capsule 3 needs to be pressure relieved, the limiting member 16 is first moved in the F5 direction to move away from the movable member 12, thereby releasing the locking of the movable member 12, and then the movable member 12 is moved in the F3 direction to open the pressure relief port 73. In this way, the medium in the storage chamber 33 can enter the seat passage 7, and the medium in the seat passage 7 can flow out through the pressure relief port 73.

[0073] In some embodiments of the present application, the angle between the second direction and the third direction is not less than 45°. For example, the angle between the second direction and the third direction can be 45°, 60°, 75°, 90°, etc., and can also be other angles not less than 45°, which will not be listed one by one here. The limiting member 16 limits and locks the movable member 12 from the radial outer side of the movable member 12, and does not occupy the axial space of the movable member 12. By arranging the angle between the second direction and the third direction to be not less than 45°, the limiting force of the limiting member 16 on the movable member 12 is larger, and the effective locking of the movable member 12 can be achieved.

[0074] In some embodiments of the present application, the second direction is perpendicular to the third direction. In other words, the angle between the second direction and the third direction is 90°. In this way, the movable member 12 can be radially limited, and it can be ensured that the movable member 12 will not retreat and the medium will not leak through the pressure relief port 73 due to the back pressure of the medium.

[0075] In some embodiments of the present application, the seat passage 7 comprises a first passage segment 71, the pressure relief port 73 is arranged on the first passage segment 71, the first passage segment 71 extends in a first direction, the movable member 12 is adapted to reciprocate in a second direction, and the movable member 12 blocks the first passage segment 71 when the movable member 12 is in the locked position, so that the movable member 12 is locked in the locked position. By locking the movable member 12 in the locked position through the limiting member 16, it can be ensured that the movable member 12 does not retreat, exit the seat passage 7, and the medium leaks through the pressure relief port 73 due to the back pressure of the medium, and the abnormal leakage of the storage capsule 3 caused by the retreat of the movable member 12 is avoided. In addition, when the movable member 12 is in the locked position, the movable member 12 blocks the first passage segment 71, and the medium no longer impacts the axial end of the movable member 12, but acts on the peripheral wall of the movable member 12. By changing the force direction of the movable member 12, the axial end force is effectively changed to non-axial force, which can ensure that the movable member 12 does not retreat, exit the seat passage 7, and the medium leaks through the pressure relief port 73 due to the back pressure of the medium, and the abnormal leakage of the storage capsule 3 caused by the retreat of the movable member 12 is avoided. The second direction and the first direction can be the same direction, or different directions.

[0076] In some embodiments of the present application, the first direction is perpendicular to the second direction, and the second direction is perpendicular to the third direction. The first direction and the third direction can be the same direction, or perpendicular to each other.

[0077] In some embodiments of the present application, as shown in Figures 5-10 , the movable member 12 is provided with a limiting groove 121, and the limiting member 16 locks the movable member 12 in the locked position when the limiting member 16 at least partially extends into the limiting groove 121.

[0078] In some embodiments of the present application, as shown in Figures 5-10 , the limiting structure 170 further comprises a limiting housing 17, the limiting housing 17 is mounted on the mounting seat 6 and / or the pressure relief structure 130, and the limiting member 16 is movably arranged in the limiting housing 17. The limiting member 16 can be close to or away from the movable member 12. Specifically, the limiting member 16 can move in the F6 direction to approach the movable member 12, and the limiting member 16 can move in the F5 direction to move away from the movable member 12.

[0079] In some embodiments of the present application, as shown in Figures 5-10 , the limiting housing 17 has a first cavity, and the first sealing structure 8 is arranged at the matching position of the limiting member 16 and the first cavity. The first sealing structure 8 can realize the sealing of the matching position of the limiting member 16 and the limiting housing 17, so as to prevent the medium from leaking from the matching position of the limiting member 16 and the limiting housing 17.

[0080] Optionally, the first sealing structure 8 can be a sealing ring or sealing glue, etc.

[0081] If the axial end face of the movable element 12 directly contacts the medium in the seat body channel 7, the movable element 12 is subjected to axial force. When the pressure or gas recoil force in the seat body channel 7 is greater than the pre-tightening force of the second sealing structure 14 and the third sealing structure 18 on the movable element 12, the movable element 12 retreats along the F3 direction, and the seat body channel 7 leaks, which can cause the storage capsule 3 to fail to function. When the storage capsule 3 is a floating water airbag and is applied to the vehicle 1000, the failure of the storage capsule 3 to function can cause the vehicle 1000 to sink, resulting in loss of the people on the vehicle and the property of the vehicle. As shown in Figures 5-6 When the axial end face of the movable element 12 is subjected to force, the limiting element 16 is in the locked state, and the movable element 12 is locked in the locked position. Due to the action of the limiting element 16, the movable element 12 will not retreat along the F3 direction due to the force on the end face, and the risk of leakage of the storage capsule 3 is well solved. When the storage capsule 3 is a floating water airbag and is applied to the vehicle 1000, the vehicle 1000 receives a larger buoyancy, and the vehicle 1000 will not sink, thereby maximizing the safety of the people on the vehicle and the property of the vehicle 1000.
