[0110] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0111] Refer to Figures 1 to 22 As shown, for the convenience of introduction, the upper and lower orientations are adopted in the corresponding drawings to facilitate the introduction of the relative position relationship between various parts in the present application, and it should not be construed as a limitation on the absolute position.

[0112] Moreover, in the present application, the up and down directions represent the first direction, and the left and right represent the second direction. Here, the up, down, left, and right are only for the convenience of introducing the specific embodiments of the present application. There is no absolute corresponding relationship between the first direction and the up and down directions, and similarly, there is no absolute corresponding relationship between the second direction and the left and right directions.

[0113] According to the first aspect of the present application, refer to Figure 1 , a container opening device 100 is provided, and the container 200 is opened by using the container opening device 100.

[0114] Refer to Figure 2 , the opening 200b of the container 200 is sealed by a sealing member 210, and the sealing member 210 can be configured as a sealing film.

[0115] Refer to Figure 2 , the sealing member 210 is welded to the container 200, with a simple structure and excellent process feasibility, and there is no need to additionally add redundant mechanisms such as a sealing member 210 retainer.

[0116] Refer to Figure 3 and Figure 4 , the container opening device 100 includes an opening device 110 and a guiding device 120.

[0117] The opening device 110 is used to generate an opening acting force for opening the container 200, and the guiding device 120 is used to guide the opening acting force along the first direction.

[0118] Among them, refer to Figure 6 , the guiding device 120 includes a guiding structure 12a.

[0119] Refer to Figures 4 to 10 , the guiding structure 12a encloses a guiding space 12a1 so that at least part of the opening acting force generated by the opening device 110 is restricted in the guiding space 12a1.

[0120] The guiding device 120 is formed with a drainage channel 12a2, and the drainage channel 12a2 communicates with the guiding space 12a1 so that the medium in the container 200 flows out of the guiding space 12a1 along the second direction.

[0121] The guiding structure 12a is at least partially located between the opening device 110 and the container 200.

[0122] Through the above technical solution, the guiding structure 12a is used to enclose the guiding space 12a1 so that the opening acting force is restricted within the guiding space 12a1. The opening acting force acts on the sealing member 210 at the opening 200b of the container 200, and the container 200 is opened by destroying the sealing member 210. At the same time, the medium will enter the guiding space 12a1 at the moment of opening, and then the medium flows out of the guiding space 12a1 along the drainage channel 12a2, completing the effect of opening the container 200. The opening process is smooth, enabling the medium to be smoothly released from the container 200.

[0123] In some embodiments, referring to Figures 4 to 10 , the opening device 110 includes an opening member 111, the guiding structure 12a includes an elastic guiding member 121, the opening member 111 is connected to the elastic guiding member 121, and the elastic guiding member 121 encloses an elastic guiding space 121a.

[0124] The opening member 111 is subjected to a pushing acting force along the first direction. Under the action of the pushing acting force, the opening member 111 can approach the container 200 in the first direction to apply an opening acting force to the sealing member 210 at the opening 200b of the container 200. Under the opening acting force, the sealing member 210 is destroyed, causing the opening of the container 200. And during the process of the opening member 111 approaching the container 200, the elastic guiding member 121 will be compressed, so that the elastic guiding space 121a is compressed.

[0125] The elastic guiding member 121 can prevent the opening member 111 from moving excessively towards the opening of the container 200. At the same time, after the elastic guiding member 121 is compressed, the elastic guiding space 121a will also be compressed, which can ensure that the opening member 111 smoothly approaches the container 200 and opens the container 200.

[0126] In some embodiments, referring to Figure 5 , the elastic guiding member 121 is configured as a columnar body with a plurality of surrounding structures.

[0127] Elastic drainage channels 121b communicating with the elastic guiding space 121a are constructed between different surrounding structures, and the elastic drainage channels 121b are used to enable the medium to flow out of the elastic guiding space 121a along the elastic drainage channels 121b.

[0128] In some embodiments, when the elastic guiding member 121 is adapted to be compressed, the opening member 111 is also biased in the first direction so that the opening member 111 can move away from the container 200, and the elastic guiding space 121a and the elastic drainage channel 121b are stretched synchronously.

[0129] When the elastic guiding space 121a is compressed, the elastic drainage channel 121b is also compressed synchronously, further ensuring that the opening member 111 can smoothly open the opening of the container 200. After the opening of the container 200 is opened, since the elastic drainage channel 121b is also compressed synchronously, the medium can converge to a certain extent in the elastic guiding space 121a.

[0130] At the same time, when the elastic drainage channel 121b is compressed, it can also filter some impurities generated when the opening 200b of the container 200 is opened, blocking the impurities from being released outside the elastic guiding space 121a, thereby protecting external devices such as airbags.

[0131] After the elastic guiding member 121 is compressed, the elastic potential energy it has will also cause the elastic guiding member 121 to recover. Then, during the recovery process, the opening member 111 can be driven away from the opening 200b of the container 200. In this process, the elastic guiding space 121a and the drainage channel are stretched synchronously, that is, stretched downward, so that the medium can flow from the container 200 into the elastic guiding space 121a and flow out of the elastic guiding space 121a along the elastic drainage channel 121b, ensuring that the medium can be released from the container 200 with a certain pressure.

[0132] It should be noted that after the elastic guiding member 121 is compressed upward, it has a tendency to recover downward. When the medium in the container flows out of the container, the medium will also exert a certain air pressure on the opening member, causing the elastic guiding member 121 to reset. When the medium pressure is relatively large, it will be compressed downward in the reverse direction.

[0133] In some embodiments, the guiding structure 12a further includes a filtering guiding member 122. The filtering guiding member 122 encloses a filtering guiding space 122a. The filtering guiding member 122 is arranged around the elastic guiding member 121, and at the same time, the elastic guiding space 121a is communicated with the filtering guiding space 122a.

[0134] The filtering guiding space 122a of the filtering guiding member 122 can further filter some impurities generated when the opening 200b of the container 200 is opened, further reducing the impurity degree of the released medium.

[0135] In some embodiments, the filtering guide 122 may be configured as a rotating body surrounding a rotation axis. Along the circumferential direction of the rotating body, a plurality of filtering drainage channels 122b are formed on the rotating body, and the elastic drainage channel 121b is communicated with the filtering drainage channel 122b.

[0136] By configuring the filtering guide 122 as a rotating body, it is possible to surround the elastic guide 121 in all directions, and by forming a plurality of filtering drainage channels 122b on the rotating body, it is also possible to filter the medium in all directions and allow the medium to pass through.

[0137] Reference Figure 6 and Figure 22 As shown in FIGS. and, the filtering guide 122 is arranged as a cylindrical structure, the elastic guide 121 is arranged as a columnar spring, and the filtering drainage channel 122b is a hole formed in the filtering guide 122.

[0138] In some embodiments, when the elastic guide 121 is suitable for being fully compressed, the height of the elastic guide 121 in the first direction is less than the height of the filtering guide 122 in the first direction, so as to ensure the elastic guide 121, avoid the elastic guide 121 from being over-compressed and losing its restoring elastic force after being subjected to a large pushing force, and at the same time avoid truncating the elastic drainage channel 121b, so as to ensure that the medium can flow out of the elastic guide space 121a along the elastic drainage channel 121b.

[0139] By using the cooperation of the elastic guide 121 and the filtering guide 122, it is ensured that the opening 200b of the container 200 is smoother while the medium can be released at a certain pressure.

[0140] In some embodiments, as shown in FIGS. Figure 22 and, the opening member 111 has a pointed end portion 111f. When the opening member 111 approaches the container 200, the pointed end portion 111f of the opening member 111 will apply an opening force to the container 200 to open the container 200. By using the pointed end portion 111f of the opening member 111 to mechanically open the opening 200b of the container 200, the pointed end portion 111f can pierce the sealing member 210 at the opening of the container 200, and the acting force is more concentrated.

[0141] Reference Figure 22 and, the angle of the pointed end portion 111f is set at 45°.

[0142] In some embodiments, the opening member 111 further includes an opening body 1111.

[0143] The part of the opening body 1111 close to the container 200 has a pointed end portion 111f. By using a part of the opening body 1111 as the pointed end portion 111f, the smooth opening of the opening 200b of the container 200 is further ensured.

[0144] Reference Figure 22 , the opening body 1111 includes a vertically formed vertical portion 1111s and a horizontally formed horizontal portion 1111h. The pointed end portion 111f is provided on the vertical portion 1111s. A pushing force is directly applied to the horizontal portion 1111h and then transmitted to the vertical portion 1111s, driving the pointed end portion 111f to approach the opening of the container 200.

[0145] The horizontal portion 1111h is configured with a boss structure. One end of the elastic guide member 121 is disposed around the boss structure on the opening body 1111 to form a connection with the opening body 1111.

[0146] In some embodiments, a groove structure may also be formed on the vertical portion 1111s along the first direction, which can provide a buffer channel for the medium.

[0147] In some embodiments, the opening device 110 further includes a blasting pusher for applying a pushing force to the horizontal portion 1111h of the opening body 1111.

[0148] The blasting pusher 112 is movably connected to the opening member 111, and a receiving cavity 111h is provided in a portion of the opening body 1111 away from the pointed end portion 111f. Along the first direction, at least a portion of the blasting pusher 112 is located in the receiving cavity 111h, and the blasting pusher 112 is adapted to push the opening body 1111 to approach the container 200 after being triggered.

[0149] The blasting pusher 112 may be configured as an ignition tube. After being ignited, the ignition tube can apply a pushing force to the horizontal portion 1111h. This way of pushing the opening member 111 to approach the container 200 is simple, reliable, and has high stability.

[0150] After the ignition tube explodes by ignition, the generated slag can be collected in the receiving cavity 111h. At the same time, the heat generated during the explosion of the ignition tube can also be concentrated to fully push the pointed end portion 111f to pierce the blasting film at the opening 200b of the container 200, that is, the pointed end portion 111f will move upward to pierce the blasting film at the opening 200b of the container 200.

[0151] In some other embodiments, the opening member 111 can also be pushed directly towards the opening of the container 200 by pushing the horizontal portion 1111h, for example, an operator directly pushes the opening member 111 and acts on the horizontal portion 1111h.

[0152] In some embodiments, reference Figure 5 and Figure 6 , the opening device 110 further includes a fixing member 113.

[0153] The fixing member 113 and the blasting driving member 112 are fixedly connected. At least part of the fixing member 113 is located in the accommodation cavity 111h, so that the fixing member 113 is located between the blasting driving member 112 and the opening body 1111.

[0154] The fixing member 113 can be set as a fixing seat with an opening. The fixing seat is also a rotating body formed around the rotation axis. The blasting driving member 112 is connected to the fixing seat, and the fixing seat is connected to the opening member 111. This connection method is more stable.

[0155] In some embodiments, referring to Figure 5 and Figure 6 , the guiding device 120 includes a mounting member 114, and the mounting member 114 is used to connect the container 200 and the opening device 110.

[0156] Along the first direction, the mounting member 114 has a communicating container mounting space 114a and device mounting space 114b. The container mounting space 114a and the device mounting space 114b are communicated through a connection port 114c. Part of the container 200 is located in the container mounting space 114a, and at least part of the opening device 110 and the guiding structure 12a are located in the device mounting space 114b. When the elastic guiding member 121 is compressed, the tip portion 111f can extend into the container mounting space 114a along the opening, so as to apply a pushing force to the sealing member 210 at the opening 200b of the container 200 to open the container 200.

[0157] The mounting member 114 is also a rotating body formed around the rotation axis. The fixing member 113, the opening member 111, and the mounting member 114 are coaxially arranged, and the rotation axis can be the central axis 10a of the opening device.

[0158] Referring to Figure 15 , the plane perpendicular to the first direction is defined as the reference plane. The projection plane S2 of the container mounting space 114a in the reference plane in the first direction falls within the projection plane S1 of the device mounting space 114b in the reference plane in the first direction.

[0159] In some embodiments, referring to Figure 11 and Figure 14 , the mounting member 114 has or is connected with a limiting portion 1231.

[0160] The elastic guiding member 121 is abutted against the limiting portion 1231 to limit the movement of the elastic guiding member 121 along the container mounting space 114a.

[0161] Referring to Figure 11, the position in the device installation space 114b of the installation part 114 close to the connection port 114c is used as the limiting part 1231, that is, the bottom wall surface of the cavity of the device installation space 114b is used as the limiting part 1231, and the elastic guiding part 121 is arranged in contact with the limiting part 1231.

[0162] Of course, the limiting part 1231 can also be arranged in the device installation space 114b. The limiting part 1231 is a block structure with a hollow cavity, and the elastic guiding part 121 is arranged in contact with the limiting part 1231.

[0163] In some embodiments, the installation part 114 has an output port 114d in the circumferential direction, so that the medium flows out of the drainage channel along the output port 114d.

[0164] Reference Figure 11 , the output port 114d is configured as a counterbore, and the medium flows out of the drainage channel along the counterbore. The number of the output ports 114d is limited according to actual use, and can be one, two or more. The specific number is not set here.

[0165] The output port 114d has a central axis, and the central axis of the output port 114d is perpendicular to the central axis 10a of the opening device.

[0166] Among them, reference Figures 9 to 13 , when only the elastic guiding part 121 is arranged in the device installation space 114b to filter and guide the medium, the medium flows out of the elastic guiding space 121a of the elastic guiding part 121 along the elastic drainage channel 121b, and continues to flow out of the elastic drainage channel 121b along the counterbore.

[0167] Reference Figure 5 And Figure 6 , when the elastic guiding part 121 and the filtering and guiding part 122 are arranged in the device installation space 114b at the same time, the medium flows out of the elastic guiding space 121a of the elastic guiding part 121 along the elastic drainage channel 121b, and flows into the filtering and guiding space 122a of the filtering and guiding part 122 and then into the filtering drainage channel 122b, and continues to flow out of the filtering drainage channel 122b from the filtering and guiding space 122a, and finally flows out of the filtering drainage channel 122b from the counterbore.

[0168] In some embodiments, reference Figure 5 , along the first direction, at least part of the output port 114d is blocked by the filtering and guiding part 122, and there is a gap 10e between the inner peripheral wall surface of the installation part 114 and the outer peripheral wall surface of the filtering and guiding part 122, so that the output port 114d is communicated with the filtering drainage channel 122b.

[0169] Of course, when only the elastic guide 121 is provided in the device installation space 114b to filter and guide the medium, a gap 10e may be provided between the inner peripheral wall surface of the installation member 114 and the elastic guide 121, so that the output port 114d communicates with the elastic drainage channel 121b.

[0170] In some embodiments, when the elastic guide 121 and the filtering guide 122 and the opening member 111 are installed in the device installation space 114b, the tip portion 111f of the opening member 111 can be abutted against the sealing member 210 of the container 200. At the same time, the arrangement of the filtering guide 122 can also prevent the tip portion 111f of the opening member 111 from hitting the sealing member 210 when the opening member 111 does not need to open the opening 200b of the container 200, so as to prevent the opening force from acting on the sealing member 210. At the same time, the elastic guide 121 can also reset the opening member 111.

[0171] In some embodiments, the filtering guide 122 includes a contact portion and a spacer portion. The contact portion is pressed against and interference-fitted with the inner wall peripheral surface of the installation member 114, and a gap 10e is provided between the spacer portion and the inner peripheral wall surface of the installation member 114. The outer peripheral wall surface of a part of the transverse portion 1111h of the opening member 111 is interference-fitted with the inner wall surface of the installation member 114.

[0172] The outer diameter of the boss structure on the transverse portion 1111h is set the same as the outer diameter of the elastic guide 121. At the moment when the opening member 111 is pushed by a force to contact the filtering guide 122, the transverse portion 1111h abuts against the filtering guide 122 so that the elastic guide 121 is not yet compressed, thereby providing a drainage channel 12a2.

[0173] According to the second aspect of the present application, referring to Figures 16 to 21 , a container opening device 100 is provided, including an opening device 110 and a guiding device 120.

[0174] The opening device 110 is used to generate an opening force to open the container 200, and the guiding device 120 is used to guide the opening force in the first direction;

[0175] Wherein, the opening device 110 includes an opening member 111, and the opening member 111 generates an opening force to open the container 200 after being triggered. The guiding device 120 includes a filtering guide 122.

[0176] The filtering guide 122 encloses a filtering guide space 122a so that at least part of the opening force generated by the opening device 110 is restricted in the filtering guide space 122a.

[0177] Circumferentially along the filtering guide member 122, a filtering drainage channel 122b is formed on the filtering guide member 122. The filtering guide space 122a communicates with the filtering drainage channel 122b so that the medium in the container 200 flows out of the filtering guide space 122a along the second direction. The filtering guide member 122 is at least partially located between the opening member 111 and the container 200.

[0178] The above-mentioned opening member 111 is configured as a trigger, for example, it can be an ignition tube. After being triggered by ignition and bursting, the ignition tube generates a large amount of heat, which acts on the sealing member 210, causing the sealing member 210 to be damaged and the container 200 to open. The filtering guide member 122 has the effect of filtering the residues generated after the sealing member 210 is damaged, preventing the residues from flowing out with the medium from the filtering guide space 122a of the filtering guide member 122.

[0179] The difference between the container opening device 100 in the above-mentioned second aspect and the container opening device 100 provided in the first aspect of the present application is that the container opening device 100 in this second aspect uses a trigger to damage the sealing film of the sealing member 210 to open the container 200, replacing the way that the opening member 111 mechanically applies an opening force to the sealing film of the sealing member 210. The other components are arranged in the same way as those of the container opening device 100 in the first aspect.

[0180] In some embodiments, the above-mentioned filtering guide member 122 can be set as a cylinder, which plays the role of converging the blasting pressure of the ignition tube. At the same time, it can filter the impurities in the whole film-breaking process. The simple filtering structure can converge energy while greatly reducing the pressure loss and improving the film-breaking ability.

[0181] According to the third aspect of the present application, refer to Figure 1 and Figure 2 , a medium release system 10 is provided, including a container 200 and a container opening device 100.

[0182] The container 200 has a storage space 200a for storing the medium. The container opening device 100 is the container opening device 100 described above. Since the medium release system 10 adopts the above-mentioned container opening device 100, it has all the beneficial effects described in the above-mentioned container opening device 100, which will not be elaborated here.

[0183] Among them, the container 200 includes a container body 220 and an opening 200b. The opening 200b is sealed by a sealing member 210, and the sealing member 210 is welded to the container body 220 to seal the opening 200b of the container body 220. The opening force of the container opening device 100 is applied to the sealing member 210 to open the opening 200b.

[0184] The types of media within the container 200 can be helium, argon, sulfur hexafluoride, carbon dioxide, nitrogen, etc., or a mixed gas of any combination. Users can apply it to different professional and technical fields, such as airbags, protection of special groups, arc extinguishing for electrical components, fire extinguishing for electrical control boxes, etc., and no specific limitations are imposed thereon.

[0185] According to the fourth aspect of the present application, there is provided an airbag, referring to Figure 1 , including an airbag body (not shown in the figure) and a media release system 10.

[0186] The airbag body has an air chamber, and the media release system 10 is the media release system 10 described above. Since the airbag adopts the above-mentioned media release system 10, it has all the beneficial effects recorded in the above-mentioned media release system 10, which will not be elaborated herein.

[0187] The output port 114d of the media release system 10 is communicatively connected to the air chamber, and the media is released into the air chamber by using the media release system 10 to complete the inflation of the air chamber of the airbag body, making the deployment of the airbag smoother.

[0188] According to the fifth aspect of the present application, referring to Figure 23 , there is provided a vehicle 1, including an airbag (not shown in the figure), and the airbag is the airbag described above.

[0189] Since the vehicle 1 adopts the above-mentioned airbag, it has all the beneficial effects recorded in the above-mentioned airbag, which will not be elaborated herein.
