Abstract

The present application relates to the technical field of battery production, and in particular, relates to an inflation and deflation connector and an inflation and deflation module for a pneumatic restraint tray. The inflation and deflation connector is configured for inflating and deflating a pneumatic restraint tray, and comprises a telescopic mating coupling assembly and a pushrod. The telescopic mating coupling assembly is internally provided with a coupling air passage extending in an axial direction and comprises a sealing gasket, and the sealing gasket is disposed within the coupling air passage. The pushrod extends in the axial direction and at least partially penetrates into the coupling air passage, and an axial end of the pushrod close to the sealing gasket is a pressure-applying end. The telescopic mating coupling assembly is capable of telescopic motion in the axial direction relative to the pushrod, allowing for adjustment of a relative position between the pressure-applying end of the pushrod and the sealing gasket. Since a sealing gasket is continuously kept in contact with a pneumatic valve of the pneumatic restraint tray during inflation and deflation, even at the instant of engagement or disconnection between a pushrod and a valve core of the pneumatic valve, the sealing gasket ensures that the pneumatic valve is in communication with a coupling air passage, thereby preventing air leakage, and ensuring accuracy of pressure values within the pneumatic restraint tray.

[0001] This application claims priority to Chinese Patent Application No. 202520147084.5, filed on January 21, 2025, entitled "Inflation / Depression Connector and Inflation / Depression Module for Airbag Tray", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of battery manufacturing technology, and in particular relates to an inflation / deflation connector and an inflation / deflation module for an airbag tray. Background Technology

[0003] Airbag trays can be used as clamps to restrain battery cells, securing and protecting them, especially providing crucial restraint force during the cell formation process. The airbags also apply more uniform pressure to the battery cells and protect them.

[0004] The pressure inside the airbag is a key parameter for the formation test of the battery cell. Currently, when the existing inflation and deflation connector is used to inflate the airbag tray, gas leakage will occur at the moment when the connector is connected to or disconnected from the air nozzle (air valve) on the airbag tray. This will cause the test data during the inflation process to deviate from the actual pressure inside the airbag. Summary of the Invention

[0005] This application provides an inflation / deflation connector and an inflation / deflation module for an airbag tray to solve the technical problem of air leakage during the connection or disconnection of existing connectors, which causes deviations in airbag pressure.

[0006] According to one aspect of this application, an inflation / deflation connector is provided, including a telescopic coupling assembly and a push rod. The telescopic coupling assembly has an axially extending connector passage and includes a sealing gasket disposed within the connector passage. The push rod extends axially and at least partially penetrates the connector passage, with the axial end of the push rod near the sealing gasket designated as the pressure-applying end. The telescopic coupling assembly is capable of axial telescopic movement relative to the push rod to adjust the relative position of the pressure-applying end of the push rod and the sealing gasket.

[0007] In an optional embodiment of this application, a mounting base structure is also included, within which a flange air passage is formed. The telescopic joint assembly is connected to the mounting base structure, and the other axial end of the push rod, away from the pressure application end, is connected to the mounting base structure. The flange air passage connects to the joint air passage.

[0008] In an optional embodiment of this application, the telescopic coupling assembly further includes a coupling and a first elastic member. The coupling has a coupling air passage, one axial end of the first elastic member is located in the flange air passage and connected to the mounting base structure, and the other axial end of the first elastic member passes through the coupling air passage and is connected to the coupling.

[0009] In an optional embodiment of this application, the telescopic coupling assembly further includes a limiting ring, and an annular boss is formed on the outer peripheral wall of the coupling. The limiting ring is sleeved on the coupling and located on the side of the annular boss closer to the mounting structure in the axial direction, and the limiting ring is spaced apart from the mounting structure in the axial direction.

[0010] In an optional embodiment of this application, the mounting structure includes an upper flange and a lower flange; the upper flange forms a radial flange air passage, and the lower flange forms an axial flange air passage and is connected to the upper flange, wherein the axial flange air passage communicates with the radial flange air passage to form a flange air passage.

[0011] In an optional embodiment of this application, a locking cylinder is also included, which is fitted over the lower flange and the expansion joint assembly.

[0012] In an optional embodiment of this application, a mounting plate and a floating mechanism are also included. The mounting plate is spaced apart from the mounting base structure and located on the side of the mounting base structure away from the telescopic coupling assembly. The floating mechanism is connected between the mounting plate and the mounting base structure to allow the mounting base structure, the telescopic coupling assembly, and the push rod to float together axially.

[0013] In an optional embodiment of this application, the floating mechanism includes at least one elastic component, which includes a pin and a second elastic member. One axial end of the pin is connected to the mounting plate, and the other axial end is connected to the mounting base structure. The second elastic member is sleeved on the pin and clamped between the mounting plate and the mounting base structure.

[0014] In an optional embodiment of this application, a limiting block is further included. One axial end of the limiting block is connected to the mounting base structure, and the other axial end is spaced apart from the mounting plate. Multiple elastic components are arranged around the limiting block.

[0015] According to another aspect of this application, an inflation / deflation module for an airbag tray is provided, including the aforementioned inflation / deflation connector; the airbag tray is provided with a valve that can be inserted into the connector's air passage. During the downward pressing of the inflation / deflation connector, the sealing gasket abuts against the valve, and the telescopic connector assembly retracts, causing the pressure end of the push rod to move downward relative to the sealing gasket to open the valve core. During the upward pressing of the inflation / deflation connector, the telescopic connector assembly extends to maintain the sealing gasket abutting against the valve, and the pressure end of the push rod moves upward relative to the sealing gasket to close the valve core.

[0016] In summary, the inflation / deflation connector and inflation / deflation module for the airbag tray provided in this application have at least the following beneficial effects:

[0017] During the inflation / deflation process, the valve on the airbag tray is inserted into the connector air passage of the telescopic coupling assembly. Because the sealing gasket always remains in contact with the valve, even when the push rod and the valve core are connected or disconnected, the sealing gasket ensures that the valve is connected to the connector air passage, preventing air leakage and ensuring the accuracy of the pressure value in the airbag tray.

[0034] Figure 1 is a partial schematic diagram of an inflation / deflation module for an airbag tray according to one embodiment of this application. Figure 2 is a partial schematic diagram of the inflation / deflation module in Figure 1 from another perspective. Figure 3 is a partial enlarged view of point S in Figure 2.

[0035] Please refer to Figures 1 to 3. The inflation / deflation module for the airbag tray 200 includes an inflation / deflation connector 100. It should be noted that, in one embodiment, the inflation / deflation module includes a drive mechanism, and the inflation / deflation connector 100 has at least vertical freedom of movement under the drive of the drive mechanism. Here, the drive mechanism can be a linear motion mechanism with a motor as the power source component.

[0036] The airbag tray 200 is equipped with a valve 210. It should be noted that the airbag tray 200 can be used to restrain the battery cell. The valve 210 has a valve core. By pressing down the valve core in the valve 210, the valve 210 can be opened to inflate and deflate the airbag.

[0037] The inflation / deflation connector 100 includes a telescopic coupling assembly 20 and a push rod 30. The telescopic coupling assembly 20 has an axially extending connector air passage D2 and includes a sealing gasket 21 disposed within the connector air passage D2.

[0038] The push rod 30 extends axially and at least partially penetrates the connector air passage D2, with the axial end of the push rod 30 near the sealing gasket 21 serving as the pressure end. The telescopic connector assembly 20 is capable of axial telescopic movement relative to the push rod 30 to adjust the relative position of the pressure end of the push rod 30 and the sealing gasket 21.

[0039] In this embodiment, the telescopic connector assembly 20 can cooperate with the valve 210, and the valve 210 can be inserted into the connector passage D2 in the telescopic connector assembly 20. In one embodiment, the charge / discharge connector 100 has vertical freedom of movement. When the valve 210 and the charge / discharge connector 100 are vertically aligned, moving the charge / discharge connector 100 downwards allows the valve 210 to be inserted into the connector passage D2.

[0040] The connector air passage D2 in the telescopic connector assembly 20 extends axially and has a sealing gasket 21 installed inside, and a push rod 30 is inserted axially. It should be noted that the axial direction here can be understood based on the location of the push rod 30 in the figure. The axial direction is the axial direction and length direction of the push rod 30, which is also the up and down direction and vertical direction.

[0041] The end of the push rod 30 near the sealing gasket 21 is the pressure end. The push rod 30 is fixed, and the telescopic coupling assembly 20 has axial telescopic freedom, that is, the telescopic coupling assembly 20 can move axially relative to the push rod 30.

[0042] It should be understood that during the axial telescopic movement of the telescopic joint assembly 20, the relative position of the pressure end of the push rod 30 and the sealing gasket 21 in the joint air passage D2 changes in the axial direction.

[0043] Specifically, during the pressing down of the inflation / deflation connector 100, the sealing gasket 21 abuts against the valve 210, the telescopic connector assembly 20 retracts and causes the pressure end of the push rod 30 to move downward relative to the sealing gasket 21 to open the valve core of the valve 210.

[0044] During the upward movement of the inflation / deflation connector 100, the telescopic connector assembly 20 extends to keep the sealing gasket 21 in contact with the valve 210, and the pressure end of the push rod 30 moves upward relative to the sealing gasket 21 to close the valve core of the valve 210.

[0045] Understandably, with the valve 210 abutting against the gasket 21, the inflation / deflation connector 100 presses down, the valve 210 obstructs the downward movement of the telescopic connector assembly 20, and correspondingly, the telescopic connector assembly 20 retracts, and the valve 210 engages with the gasket 21 to seal.

[0046] As the pressure continues to be applied, the pressure end of the push rod 30 moves downward relative to the sealing gasket 21, that is, moves downward relative to the valve valve 210. The pressure end of the push rod 30 can apply pressure to the valve core of the valve valve 210 to open the valve core of the valve valve 210. At this time, the airbag tray 200 can be inflated or deflated.

[0047] After inflation and deflation are completed, the inflation / deflation connector 100 moves upward, and the push rod 30 rises relative to the sealing gasket 21, that is, the push rod 30 moves upward relative to the valve 210 until the pressure end of the push rod 30 releases the valve core to close the valve 210. At the same time, the telescopic connector assembly 20 extends to ensure that the valve 210 is in contact with the sealing gasket 21 to continue to maintain the seal.

[0048] As can be seen, during the process of inserting valve 210 into connector air passage D2 for inflation and deflation, since the sealing gasket 21 is always in contact with valve 210, even when push rod 30 and valve core of valve 210 are connected or disconnected, sealing gasket 21 ensures that valve 210 is connected to connector air passage D2, avoids air leakage, and ensures the accuracy of pressure value in airbag tray 200.

[0049] In a further optional embodiment, the inflation / deflation connector 100 further includes a mounting base structure 10, in which a flange air passage D1 is formed.

[0050] The telescopic joint assembly 20 is connected to the mounting base structure 10, the other axial end of the push rod 30 away from the pressure end is connected to the mounting base structure 10, and the flange air passage D1 is connected to the joint air passage D2.

[0051] In this embodiment, the inflation / deflation connector 100 also includes a mounting base structure 10, the telescopic connector assembly 20 is mounted on the mounting base structure 10, and the other end of the push rod 30 is fixed to the mounting base structure 10. Furthermore, a flange air passage D1 is formed within the mounting base structure 10, and the flange air passage D1 and the connector air passage D2 are connected to form a passage that allows gas flow.

[0052] In a further optional embodiment, the mounting structure 10 includes an upper flange 11 and a lower flange 12. The upper flange 11 forms a radial flange air passage D11, and the lower flange 12 forms an axial flange air passage D12 and is connected to the upper flange 11. The axial flange air passage D12 communicates with the radial flange air passage D11 to form a flange air passage D1.

[0053] In this embodiment, the mounting base structure 10 is a flange splicing structure, specifically formed by splicing an upper flange 11 and a lower flange 12 in the vertical direction. The upper flange 11 is provided with a radial flange air passage D11, and the lower flange 12 is provided with an axial flange air passage D12. The axial flange air passage D12 connects with the radial flange air passage D11, together forming a flange air passage D1.

[0054] In practical applications, the connecting sidewalls of the lower flange 12 and the upper flange 11 are provided with several fine air holes, through which the radial flange air passage D11 and the axial flange air passage D12 are connected.

[0055] It should be noted that, due to the viewing angle, only the middle part of the radial flange air passage D11 is shown in Figure 3. The connector air passage D2 is connected to the axial flange air passage D12 to connect the connector air passage D2 to the entire flange air passage D1.

[0056] In practical applications, the inflation / deflation connector 100 also includes a pressure detection unit 60 and a gas connection 70, with the pressure detection unit 60 and the gas connection 70 respectively connected to both ends of the radial flange gas passage D11.

[0057] By connecting to an external airway via the airway connector 70, airflow can be introduced or drawn out. The pressure detection unit 60 can detect the pressure in the airbag tray 200 to assess whether the pressure value is appropriate. In specific applications, the pressure detection unit 60 can be a barometer, pressure sensor, etc.

[0058] In the embodiment shown in Figure 3, the axial end of the push rod 30 away from the pressure end is fixed to the lower flange 12 by screws 31, and the axial part is located in the axial flange air passage D12, while the other axial part passes through the joint air passage D2.

[0059] In one embodiment, a first sealing ring 13 is provided between the upper flange 11 and the lower flange 12 to ensure the sealing of the joint and prevent air leakage.

[0060] In some alternative embodiments, the telescopic coupling assembly 20 further includes a coupling 22 and a first elastic member 23. The coupling 22 forms a coupling air passage D2, one axial end of the first elastic member 23 is located in the flange air passage D1 and connected to the mounting base structure 10, and the other axial end of the first elastic member 23 passes through the coupling air passage D2 and is connected to the coupling 22.

[0061] In this embodiment, the telescopic connector assembly 20 also includes a connector 22 and a first elastic member 23. The connector 22 is provided with a connector air passage D2. The first elastic member 23 is clamped between the mounting base structure 10 and the connector 22 to provide the connector 22 with a degree of freedom of telescopic movement.

[0062] In a specific application, one axial end of the first elastic element 23 is connected to the top side wall of the lower flange 12 in the mounting structure 10 and is located in the axial flange air passage D12 in the flange air passage D1. The inner peripheral wall of the connector air passage D2 in the connector 22 has a step. One axial end of the first elastic element 23 is inserted into the connector air passage D2 and can be connected to the step.

[0063] In one embodiment, the first elastic member 23 is sleeved on the top rod 30, and is limited by the top rod 30 to prevent the first elastic member 23 from popping out. In another embodiment, there are multiple first elastic members 23, which are arranged circumferentially around the top rod 30.

[0064] In the embodiment shown in Figure 3, the upper axial end of the connector 22 is inserted into the axial flange air passage D12, and the upper axial end of the connector 22 is provided with at least one second sealing ring 222 to ensure the sealing performance of the connector 22 and the lower flange 12, that is, to ensure the airtight connection between the axial flange air passage D12 and the connector air passage D2. In the illustrated embodiment, there are two second sealing rings 222, but it is not limited to this.

[0065] In a further optional embodiment, the telescopic connector assembly 20 further includes a limiting ring 24, and an annular boss 221 is formed on the outer peripheral wall of the connector 22.

[0066] The limiting ring 24 is sleeved on the butt joint 22 and located on the side of the annular boss 221 that is axially close to the mounting base structure 10. The limiting ring 24 is arranged axially at intervals from the mounting base structure 10.

[0067] In this embodiment, the outer peripheral wall of the connector 22 is provided with an annular boss 221, which is used to install the limiting ring 24. Specifically, the limiting ring 24 abuts against the annular boss 221 and is spaced apart from the bottom end of the lower flange 12 in the mounting base structure 10.

[0068] Understandably, during the retraction of the butt joint 22, the limiting ring 24 can be driven to abut against the bottom end of the lower flange 12. In other words, the distance between the limiting ring 24 and the bottom end of the lower flange 12 is the maximum retraction stroke of the butt joint 22.

[0069] In some alternative embodiments, the inflation / deflation connector 100 further includes a locking cylinder 90, which is fitted over the lower flange 12 and the telescopic connector assembly 20.

[0070] In this embodiment, the telescopic coupling assembly 20 is connected to the lower flange 12 via the locking cylinder 90. In specific applications, the upper axial end of the locking cylinder 90 is threaded to the lower axial end of the lower flange 12, and the lower axial end of the locking cylinder 90 is sleeved on the coupling 22 and engaged by the annular boss 221, so that the locking cylinder 90 is fixedly connected to the lower flange 12, but movably connected to the coupling 22.

[0071] In a further optional embodiment, the inflation / deflation connector 100 further includes a mounting plate 40 and a floating mechanism 50, wherein the mounting plate 40 is spaced apart from the mounting base structure 10 and is located on the side of the mounting base structure 10 away from the telescopic connector assembly 20.

[0072] The floating mechanism 50 is connected between the mounting plate 40 and the mounting base structure 10 so that the mounting base structure 10, the telescopic coupling assembly 20 and the push rod 30 float together in the axial direction.

[0073] In this embodiment, the mounting base structure 10 is connected to the mounting plate 40 via a floating mechanism 50, and the driving mechanism in the inflation / deflation module can be connected to the mounting plate 40, thereby driving the entire inflation / deflation connector 100 to move up and down.

[0074] The floating mechanism 50 allows the mounting base structure 10 to drive the telescopic connector assembly 20 and the push rod 30 to have floating freedom in the axial direction, so as to realize the floating docking of the inflation / deflation connector 100 with the valve 210 in the airbag tray 200, avoiding rigid docking between the inflation / deflation connector 100 and the valve 210, and ensuring safety during the docking process.

[0075] In a further optional embodiment, the floating mechanism 50 includes at least one elastic component 51, which includes a pin 511 and a second elastic element 512.

[0076] One axial end of the pin 511 is connected to the mounting plate 40, and the other axial end is connected to the mounting base structure 10. The second elastic member 512 is sleeved on the pin 511 and clamped between the mounting plate 40 and the mounting base structure 10.

[0077] In this embodiment, the floating mechanism 50 includes an elastic component 51, which is connected between the mounting base structure 10 and the mounting plate 40, and the floating function is realized through the elastic component 51.

[0078] The elastic component 51 includes at least a pin 511 and a second elastic element 512. The upper flange 11 in the mounting base structure 10 is connected to the mounting plate 40 by the pin 511. The second elastic element 512 is sleeved on the pin 511 and sandwiched between the upper flange 11 and the mounting plate 40. The second elastic element 512 can extend and retract during the docking process so that the mounting base structure 10, the telescopic coupling assembly 20 and the top rod 30 can float together in the axial direction.

[0079] In a further optional embodiment, the inflation / deflation connector 100 further includes a limiting block 80, one axial end of which is connected to the mounting base structure 10, and the other axial end is spaced apart from the mounting plate 40.

[0080] In this embodiment, the axial clearance between the limiting block 80 and the mounting plate 40 defines the maximum possible floating stroke. Furthermore, there can be multiple elastic components 51 arranged around the limiting block 80. In specific applications, the multiple elastic components 51 can be arranged at uniform intervals circumferentially. In the illustrated embodiment, there are three elastic components 51.

[0081] In another embodiment, the number of elastic components 51 may be one. The pin 511 in the elastic component 51 is a hollow pin with a diameter greater than that of the limiting block 80 and is sleeved on the limiting block 80 and has a clearance fit with the limiting block 80. The second elastic element 512 is sleeved on the limiting block 80 and sandwiched between the upper flange 11 and the mounting plate 40.

[0082] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
