Air spring airbag and buckle assembly device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 202311132412.6 filed with the Chinese Patent Office on September 4, 2023, entitled “Air Spring Airbag and Buckle Assembly Device,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of vibration damping element assembly, and in particular to an air spring airbag and buckle assembly device. Background Art

[0004] Air springs are vibration damping devices installed on railway vehicles to isolate vibrations between the bogie and the vehicle body, thereby providing a comfortable ride for passengers.

[0005] An air spring is assembled from an airbag and a retaining ring. The retaining ring is a closed ring-shaped component made of metal, which is relatively rigid and not easily deformed. The airbag is a flexible component made of a rubber composite material, whose upper and lower mating parts are relatively rigid and not easily deformed, while the remaining parts can produce relatively large deformations when a large external force is applied. When assembling an air spring, the retaining ring needs to be fitted onto the upper mating part of the airbag. Since the upper mating part of the airbag is relatively rigid, the retaining ring can only be fitted upward from the bottom of the airbag. In addition, due to the structural characteristics of the air spring, the airbag body itself is much larger than the retaining ring, and the retaining ring is a closed ring-shaped component. Therefore, the airbag body needs to be squeezed by external force to deform it, and then inserted into the retaining ring until the retaining ring and the upper mating part of the airbag are fully assembled into place.

[0006] At present, air springs are assembled manually, which requires assemblers to squeeze the airbag vigorously, which consumes a lot of physical strength and makes assembly difficult. In addition, the rigidity of airbags of different specifications also varies. The smaller the airbag, the greater the rigidity and the more difficult it is to deform, making the assembly of the air spring more difficult, and even impossible to complete manually.

[0007] Application Contents

[0008] In view of this, the purpose of this application includes providing an air spring airbag and buckle assembly device to solve, to a certain extent, the technical problem of the difficulty in manually assembling air springs in the prior art.

[0009] In order to achieve the above objectives, the technical solutions adopted in the embodiments of the present application are as follows:

[0010] The present application provides an air spring airbag and buckle assembly device, comprising:

[0011] A first drive assembly includes a first drive member, an outward pushing assembly, and an extrusion assembly; the outward pushing assembly abuts against the inner wall of the airbag, and the extrusion assembly abuts against the outer wall of the airbag; the first drive member is connected to the outward pushing assembly and the extrusion assembly, respectively, to drive the outward pushing assembly and the extrusion assembly to move toward or away from each other;

[0012] The second driving component includes a second driving member and a push-pull member; a buckle is installed on the push-pull member, and the second driving member is connected to the push-pull member to drive the push-pull member to move along the axial direction of the buckle, thereby driving the buckle to be assembled on the outer side wall of the airbag.

[0013] In the above technical solution, further, the first driving member has a first driving end, and the first driving end is capable of reciprocating along the axis direction of the airbag;

[0014] The outward pushing assembly includes an outward pushing arm and a first connecting member, wherein the outward pushing arm abuts against the inner side wall of the airbag, and the first connecting member is hinged to the outward pushing arm and the first driving end respectively;

[0015] The extrusion assembly includes an extrusion arm and a second connecting member, the extrusion arm abuts against the outer side wall of the airbag, and the second connecting member is hinged to the extrusion arm and the first driving end respectively.

[0016] The above-described structure enables both the push assembly and the squeeze assembly to be formed as a connecting rod structure, thereby ensuring flexible and reliable movement of the push assembly and the squeeze assembly to meet the requirements of airbag compression. This also makes the structure of the first drive assembly more compact, making the air spring airbag and buckle assembly device of the present application suitable for air springs with very small airbag inner diameters. Furthermore, the push arm squeezes the inner wall of the airbag while the squeeze arm squeezes the outer wall of the airbag, thereby ensuring that the airbag is vertically fixed, thereby ensuring that the elastic airbag will not be squeezed out during the squeezing process.

[0017] In any of the above technical solutions, further, the first driving end is formed into a rod-shaped structure, the side wall of the first driving end is provided with a first connecting part and a second connecting part, the first connecting member is hinged to the first connecting part, and the second connecting member is hinged to the second connecting part.

[0018] The above structure can be used to achieve the following: the first driving end of the rod-shaped structure can be suitable for assembling airbags and buckles of different sizes and specifications, and the cost of the device can be reduced.

[0019] In any of the above technical solutions, further, along the length direction of the first driving end, the first connecting portion and the second connecting portion are spaced apart.

[0020] The above structure can be used to ensure that, under the driving action of the first driving member, the push-out assembly and the extrusion assembly move along a trajectory that can achieve extrusion of the airbag.

[0021] In any of the above technical solutions, further, the first connecting member is formed into a rod-shaped structure that can be extended and retracted along its length direction, and the outward-pushing arm and the first driving end are respectively arranged at two ends of the first connecting member in the length direction.

[0022] The above structure can be used to achieve the following: the first connecting member can passively extend or shorten with the reciprocating motion of the first driving end. When the first driving end extends, the length of the first connecting member becomes longer, thereby reducing the inward contraction amplitude of the push-out arm; when the first driving end contracts, the length of the first connecting member becomes shorter, thereby reducing the outward opening amplitude of the push-out arm, so that the push-out arm has a certain adaptive flexibility, which can further expand the size range of the airbag that can be clamped by the first driving assembly, thereby meeting the assembly requirements of more air springs of different specifications.

[0023] In any of the above technical solutions, further, the push-out arm and the squeeze arm are both formed into a curved rod-shaped structure to conform to the airbag.

[0024] The above structure can achieve the following: the curved rod-shaped structure conforms to the airbag, so that the contact area between the push-out arm and the squeeze arm and the airbag is increased to facilitate force application.

[0025] In any of the above technical solutions, further, the outward-pushing arm is formed with a clamping portion protruding toward the airbag, and the clamping portion is configured to be clamped on the top of the airbag.

[0026] The above structure can achieve the following: the clamping portion can position the airbag, ensuring that the airbag will not separate from the push-out arm and the squeeze arm during the process of squeezing and deforming, thereby improving the stability and reliability of the airbag squeezing process.

[0027] In any of the above technical solutions, further, a protective member is provided on the side of the squeezing arm and the pushing arm facing the airbag, and the protective member can abut against the airbag.

[0028] The above structure can achieve the following: the protective member can protect the airbag, preventing the squeezing arm or the push-out arm from damaging the surface of the airbag when squeezing the airbag.

[0029] In any of the above technical solutions, further, the extrapolation components and the extrusion components in the first drive component are provided in multiple groups, multiple groups of the extrapolation components are arranged around the outer wall of the airbag at intervals, and multiple groups of the extrusion components are arranged around the inner wall of the airbag at intervals.

[0030] The above structure can ensure that the airbag can be compressed proportionally, reduce the friction between the airbag and the buckle during assembly, thereby protecting the surface of the airbag and reducing the wear of the buckle surface protective layer.

[0031] In any of the above technical solutions, further, the push-pull member is formed as an annular structure surrounding the outside of the first driving component, and the top of the push-pull member has a recessed positioning portion, and the positioning portion is configured to assemble the buckle; the second driving member is arranged below the push-pull member.

[0032] The above structure can achieve the following: the recessed positioning portion can ensure that the push-pull member and the buckle are assembled reliably, and prevent the buckle from slipping off the top of the push-pull member during assembly with the airbag.

[0033] In any of the above technical solutions, further, a mounting portion is formed on the top of the outer side wall of the airbag, and the mounting portion is configured to assemble the buckle; the first driving component can squeeze the airbag to deform, and the buckle passes through the deformed airbag from the bottom of the airbag and is assembled on the mounting portion.

[0034] The above structure can achieve the following: since the top of the airbag is relatively rigid and not easily deformed, the buckle passes through the bottom of the airbag for assembly, which can effectively improve the assembly efficiency.

[0035] In any of the above technical solutions, further, the air spring airbag and buckle assembly device further includes:

[0036] A housing, wherein the first drive assembly and the second drive assembly are both arranged inside the housing.

[0037] The above structure can be used to achieve the following: the shell can provide protection, which can not only prevent external impurities or moisture from entering the first drive component assembly and the second drive component, thereby extending the service life of the device, but also protect the assembler to avoid assembly failure causing the buckle or airbag to detach from the device and cause safety hazards.

[0038] In any of the above technical solutions, further, a support member is provided inside the shell, and the push-out assembly and the extrusion assembly are hinged to the support member respectively.

[0039] The above structure can achieve the following: the push arm and the squeeze arm swing around their hinges with the support member as the center of the circle, making the push arm and the squeeze arm open outward or contract inward more smoothly, avoiding dead points in movement.

[0040] In any of the above technical solutions, further, the top of the shell has an opening, and the air spring airbag and buckle assembly device also includes an end cover arranged on the top of the shell.

[0041] The above structure can be used to achieve the following: the end cover is closed during the assembly process of the airbag and the buckle, so as to further achieve protection and ensure safe and reliable assembly.

[0042] In any of the above technical solutions, further, the air spring airbag and buckle assembly device further includes:

[0043] An electronic control module is connected to the first drive assembly and the second drive assembly.

[0044] The above structure enables the assembler to control the first drive member and the second drive member through the electronic control module to automatically assemble the airbag and the buckle in the housing, thereby completely simplifying manual operations.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] The air spring airbag and buckle assembly device provided in the present application includes: a first drive component, including a first drive member, an outward push component and an extrusion component; the outward push component abuts the inner wall of the airbag, and the extrusion component abuts the outer wall of the airbag; the first drive member is connected to the outward push component and the extrusion component respectively to drive the outward push component and the extrusion component to move closer to or away from each other; the second drive component includes a second drive member and a push-pull member; the buckle is installed on the push-pull member, and the second drive member is connected to the push-pull member to drive the push-pull member to move along the axial direction of the buckle, thereby driving the buckle to be assembled on the outer wall of the airbag.

[0047] The air spring airbag and buckle assembly device provided in the present application realizes the extrusion deformation of the airbag through the joint action of the push component and the extrusion component, and cooperates with the second driving component to drive the push-pull component to move along the axial direction of the buckle, so that the buckle is assembled on the airbag. In this way, the assembly of the air spring is automatically completed, the assembly quality is guaranteed, the labor intensity of the assemblers is greatly reduced, and the assembly requirements of air spring airbags and buckles of different specifications are met.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0062] The air spring airbag and buckle assembly device according to an embodiment of the present application will be described below with reference to FIG. 1 to FIG. 7 .

[0063] The air spring includes an annular airbag 60 and a buckle 70 , wherein the buckle 70 is formed into a closed annular structure, and a mounting portion 63 for assembling the buckle 70 is formed on the top of the outer sidewall 61 of the airbag 60 .

[0064] The air spring airbag and buckle assembly device includes a first drive assembly and a second drive assembly. The first drive assembly is used to squeeze the airbag 60 to deform, and the second drive assembly is used to fit the buckle 70 onto the airbag 60 to assemble the air spring.

[0065] Preferably, the first drive component includes a first drive member 11, an extrapolation component 12 and an extrusion component 13; the first drive member 11 is connected to the extrapolation component 12 and the extrusion component 13 respectively, the extrapolation component 12 abuts against the inner wall 62 of the airbag 60, and the extrusion component 13 abuts against the outer wall 61 of the airbag 60, that is, the airbag 60 is installed between the extrapolation component 12 and the extrusion component 13; the first drive member 11 can drive the extrapolation component 12 and the extrusion component 13 to move closer to or away from each other, so that when the airbag 60 is squeezed, the expansion of the inner diameter of the airbag 60 and the contraction of the outer diameter of the airbag 60 are achieved at the same time. Compared with the method of squeezing only from the outer diameter of the airbag, the simultaneous squeezing of the inner diameter and the outer diameter can ensure that the airbag 60 is vertically fixed, and ensure that the elastic airbag 60 is not squeezed out during the extrusion process (that is, it will not be separated from the extrapolation component 12 and / or the extrusion component 13).

[0066] The first driving member 11 drives the push assembly 12 and the extrusion assembly 13 to move closer to or away from each other to fix the airbag 60, so that the air spring airbag and buckle assembly device can fix and clamp airbags 60 of different sizes without replacing the first driving assembly.

[0067] It should be noted that the advantages of this application also include: using only a first drive member 11, it is possible to control the relative movement or the movement of the push assembly 12 and the squeeze assembly 13 to squeeze the airbag 60. This ingenious design can also achieve the goals of reducing costs and saving energy. Furthermore, the structure of the first drive assembly is more compact, making the air spring airbag and buckle assembly device of this application suitable for air springs with airbags 60 having very small inner diameters.

[0068] Preferably, the second drive assembly includes a second drive member 21 and a push-pull member 22; the buckle 70 is installed on the push-pull member 22, and the second drive member 21 is connected to the push-pull member 22 to drive the push-pull member 22 to move along the axial direction of the buckle 70, thereby driving the buckle 70 to be assembled on the outer wall 61 of the airbag 60 in a sleeve manner.

[0069] Specifically, the push-pull member 22 is formed as an annular structure surrounding the outside of the first drive assembly. The top of the push-pull member 22 has a recessed positioning portion 221 for mounting the buckle 70. The second drive member 21 is disposed below the push-pull member 22 and has a second driving end 211 connected to the bottom of the push-pull member 22 to drive the push-pull member 22 to rise or fall. The first drive assembly can squeeze the airbag 60 to deform, and the buckle 70 passes through the deformed airbag 60 from the bottom of the airbag 60 and is assembled to the mounting portion 63.

[0070] The assembly process of the airbag 60 and the buckle 70 is as follows:

[0071] S1. The first driving member 11 drives the pushing assembly 12 and the extrusion group to move closer to each other, so that the airbag 60 is squeezed and deformed to ensure that the buckle 70 passes through;

[0072] S2. The buckle 70 is installed on the push-pull member 22. The second driving member 21 drives the push-pull member 22 to move toward the airbag 60, thereby driving the buckle 70 to pass through the squeezed and deformed airbag 60 and transport the buckle 70 to the mounting portion 63.

[0073] S3. After the buckle 70 is assembled on the mounting portion 63, the second driving member 21 drives the push-pull member 22 to move away from the airbag 60 to avoid interfering with the rebound of the airbag 60.

[0074] S4. The first driving member 11 drives the pushing assembly 12 and the squeezing assembly 13 to move away from each other, and the deformed airbag 60 gradually rebounds and returns to a normal state where the main body is not affected by external forces, thereby completing the assembly of the air spring airbag and the buckle.

[0075] Preferably, the extrapolation components 12 and the extrusion components 13 in the first drive component are provided with multiple groups, and the multiple groups of extrapolation components 12 and extrusion components 13 are synchronously driven by a first drive member 11. The multiple groups of extrapolation components 12 are arranged at intervals around the outer wall 61 of the airbag 60, and the multiple groups of extrusion components 13 are arranged at intervals around the inner wall 62 of the airbag 60, so that the airbag 60 is squeezed evenly, ensuring that the airbag 60 can be compressed proportionally, reducing the friction between the airbag 60 and the buckle 70 during the assembly process, protecting the surface of the airbag 60 while also reducing the wear on the surface protective layer of the buckle 70 (such as paint, electroplating or anodizing).

[0076] Optionally, multiple groups of pushing assemblies 12 and multiple groups of squeezing assemblies 13 are alternately arranged around the circumference of the airbag 60 .

[0077] Optionally, each group of extrapolation components 12 and each group of extrusion components 13 are correspondingly arranged along the radial direction of the airbag 60 .

[0078] It should be noted that, in this embodiment, the first driving member 11 and the second driving member 21 can both be electric push rods, pneumatic push rods, hydraulic push-pull cylinders, or other power sources that can achieve the above-mentioned driving effect.

[0079] Preferably, the first driving member 11 has a first driving end 111. For example, when the first driving member 11 is an electric push rod, the first driving end 111 is a push rod that can reciprocate and extend, and the first driving end 111 can reciprocate along the axis of the airbag 60. The structure of the second driving end 211 can be the same as that of the first driving end 111.

[0080] Preferably, the first driving member 11 is arranged below the push assembly 12 and the extrusion assembly 13 , and the first driving end 111 can move upward to extend or move downward to retract; the second driving member 21 is arranged below the push-pull member 22 .

[0081] The push-out assembly 12 and the squeeze assembly 13 are both formed as a connecting rod mechanism, thereby ensuring that the push-out assembly 12 and the squeeze assembly 13 can move flexibly and reliably to meet the requirements of the compressed airbag 60 .

[0082] Specifically, the outward push assembly 12 includes an outward push arm 121 and a first connecting member 122. The outward push arm 121 abuts against the inner wall 62 of the airbag 60. The first connecting member 122 is hinged to the outward push arm 121 and the first driving end 111 respectively. When the first driving end 111 extends, the first connecting member 122 is simultaneously lifted upward, thereby driving the outward push arm 121 to retract inward; conversely, when the first driving end 111 retracts, the first connecting member 122 moves downward synchronously and drives the outward push arm 121 to open outward.

[0083] More specifically, the extrusion assembly 13 includes an extrusion arm 131 and a second connecting member 132. The extrusion arm 131 abuts against the outer wall 61 of the airbag 60, and the second connecting member 132 is hinged to the extrusion arm 131 and the first driving end 111 respectively. When the first driving end 111 extends, the second connecting member 132 is simultaneously lifted upward, thereby pushing the extrusion arm 131 to open outward; conversely, when the first driving end 111 contracts, the second connecting member 132 moves downward synchronously and drives the extrusion arm 131 to contract inward, so that when the first driving end 111 extends, the extrusion arm 131 and the outward pushing arm 121 move closer to each other, and when the first driving end 111 contracts, the extrusion arm 131 and the outward pushing arm 121 move away from each other.

[0084] Preferably, the first driving end 111 is formed as a rod-shaped structure, and the side wall of the first driving end 111 is provided with a first connecting portion 1111 and a second connecting portion 1112, the first connecting member 122 is hinged to the first connecting portion 1111, and the second connecting member 132 is hinged to the second connecting portion 1112; along the length direction of the first driving end 111, the first connecting portion 1111 and the second connecting portion 1112 are spaced apart to ensure that under the driving action of the first driving member 11, the extrapolation component 12 and the extrusion component 13 move along a trajectory that can realize the extrusion of the airbag 60.

[0085] Specifically, the first connection portion 1111 and the second connection portion 1112 may be formed as a plate-like structure protruding along the circumferential side wall of the first driving end 111 so as to be connected to the plurality of first connection members 122 or the second connection members 132 .

[0086] Preferably, the first connecting portion 1111 is arranged above the second connecting portion 1112. However, the relative position and spacing between the first connecting portion 1111 and the second connecting portion 1112 can be adjusted according to the actual extrusion conditions of the airbag 60, as long as the requirements for extruding airbags 60 of different specifications can be guaranteed.

[0087] The purpose of squeezing the airbag 60 to deform is to fit the buckle 70 onto the outer wall 61 of the airbag 60. Therefore, the movement amplitude of the squeezing assembly 13 is preferably greater than the movement amplitude of the outward pushing assembly 12, so that the outer wall 61 of the airbag 60 is deformed more significantly, thereby ensuring smooth passage of the buckle 70. To this end, the first connecting member 122 is preferably formed into a rod-shaped structure that can be extended and retracted along its length. The outward pushing arm 121 and the first driving end 111 are respectively disposed at the two ends of the first connecting member 122 in the length direction. In this way, the first connecting member 122 passively extends or contracts with the reciprocating motion of the first driving end 111.

[0088] Specifically, when the first drive end 111 extends, the length of the first connecting member 122 increases, thereby reducing the extent to which the push arm 121 contracts inwardly; when the first drive end 111 contracts, the length of the first connecting member 122 decreases, thereby reducing the extent to which the push arm 121 expands outwardly, allowing the push arm 121 to have a certain degree of adaptive flexibility. In addition, because the push arm 121 has a certain degree of adaptive flexibility, the size range of the airbag 60 that can be clamped by the first drive assembly can be further expanded, thereby meeting the assembly requirements of more air springs of different specifications. Preferably, the first connecting member 122 is formed into a telescopic sleeve structure (for example, using a telescopic connecting cylinder).

[0089] Preferably, the push arm 121 and the squeeze arm 131 are both formed into a curved rod-like structure to conform to the airbag 60 , thereby increasing the contact area between the push arm 121 and the squeeze arm 131 and the airbag 60 to apply force.

[0090] Preferably, the push arm 121 is formed with a clamping portion 1211 protruding toward the airbag 60, which is used to clamp the top of the airbag 60, thereby positioning the airbag 60 and ensuring that the airbag 60 will not separate from the push arm 121 and the squeezing arm 131 during the squeezing and deformation process.

[0091] Preferably, a protective member 30 is provided on the side of the squeezing arm 131 and the outward-pushing arm 121 facing the airbag 60. The protective member 30 can abut against the airbag 60 to protect the airbag 60 and prevent the squeezing arm 131 or the outward-pushing arm 121 from damaging the surface of the airbag 60 when squeezing the airbag 60. The protective member 30 is preferably made of nylon to have a certain degree of wear resistance.

[0092] The air spring airbag and buckle assembly device also includes a shell 40, the first drive assembly and the second drive assembly are both arranged inside the shell 40, a support member 41 is provided inside the shell 40, and the push assembly 12 and the extrusion assembly 13 are respectively hinged to the support member 41.

[0093] Specifically, the main bodies of the first driving member 11 and the second driving member 21 are both mounted on the inner wall of the housing 40, such as the bottom wall. The support member 41 is formed into a plate-like structure and is spaced a certain distance from the bottom wall of the housing 40. The main body of the first driving member 11 is disposed between the support member 41 and the bottom wall of the housing 40. The support member 41 is provided with a through hole extending through the main body thereof for the first driving end 111 to extend outward. The longitudinal ends of the outward pushing arm 121 and the extrusion arm 131 are hingedly connected to the support member 41, so that the outward pushing arm 121 and the extrusion arm 131 swing about their hinged connection with the support member 41, thereby enabling the outward pushing arm 121 and the extrusion arm 131 to expand outward or contract inward.

[0094] Preferably, the top of the housing 40 has an opening, through which the airbag 60 and retaining ring 70 are placed into the housing 40 or removed from the assembled air spring. The air spring airbag and retaining ring assembly device further includes an end cap 50 disposed on the top of the housing 40 to at least partially close the opening. During the assembly of the airbag 60 and retaining ring 70, the end cap 50 is closed; after the air spring airbag and retaining ring assembly is complete or when the airbag 60 and retaining ring 70 need to be placed into the housing 40, the end cap 50 is opened.

[0095] Optionally, the end cover 50 is formed into a structure that opens and closes in the horizontal direction.

[0096] It should be noted that when the buckle 70 needs to be placed, the end cover 50 is opened and the second driving end 211 is extended to the top; after the buckle 70 is placed on the positioning portion 221, the second driving end 211 is retracted to the bottom. At this time, the airbag 60 can be placed between the push-out assembly 12 and the extrusion assembly 13, and then the end cover 50 is closed.

[0097] The air spring airbag and buckle assembly device also includes an electronic control module 80 connected to the first drive assembly and the second drive assembly. The electronic control module 80 includes an operating button or an operating panel disposed on the outer wall of the housing 40. The assembler can control the first drive member 11 and the second drive member 21 by operating the operating button or the operating panel to automatically assemble the airbag 60 and the buckle 70 within the housing 40. Furthermore, the electronic control module 80 can be a control program module with an automatic execution function, which can automatically execute the entire set of action processes of the drive assembly with a single button, thus completely simplifying manual operation.

[0098] Preferably, the end cover 50 can also be connected to the electronic control module 80, so that the opening and closing of the end cover 50 can be automatically controlled. After the air spring airbag and the buckle are assembled, the end cover 50 can be automatically opened to facilitate the assembly personnel to take it out.

[0099] It can be seen that the air spring airbag and buckle assembly device provided by the present application has a simple and compact structure and low preparation cost. The airbag is squeezed and deformed by the joint action of the push component and the extrusion component, and the push-pull component is driven to move along the axial direction of the buckle in cooperation with the second driving member, so that the buckle is assembled on the outer wall of the airbag. In this way, the assembly of the air spring airbag and the buckle is automatically completed, the assembly quality is guaranteed, the labor intensity of the assemblers is greatly reduced, and the assembly requirements of air spring airbags and buckles of different specifications are met. Furthermore, by providing multiple groups of push components and extrusion components, the airbag is squeezed evenly, ensuring that the airbag is compressed in proportion, thereby protecting the surface of the airbag while reducing the wear on the protective layer on the surface of the buckle. In addition, the first connecting member of the telescopic structure can achieve different opening and contraction amplitudes of the extrusion arm and the push arm, and the structure is simple and compact.
