[0038] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present utility model, the following is described in detail in conjunction with the implementation manners and with reference to the accompanying drawings.

[0039] This embodiment discloses an automatic inflation and deflation device for automatically docking with an air nozzle to inflate or deflate an airbag with an air nozzle. As Figure 14 , it should be noted here that the air nozzle Q, also called the valve core, is a commonly used device in the art, and its structure and working principle will not be described in detail.

[0040] As Figures 1 to 6 , the automatic inflation and deflation device includes a base 80, a frame 81 and a telescopic driver 83.

[0041] The base 80 is connected to the frame 81 through a first sliding mechanism 82, and the telescopic driver 83 is connected to the frame 81. Based on the first sliding mechanism 82, the telescopic driver 83 can drive the frame 81 to reciprocate along the first direction F. In practice, the first direction F is the direction of approaching or departing from the air nozzle Q.

[0042] An air port connector M is provided on the frame 81, and the air port connector M includes a connection base 4 and an adapter 1.

[0043] The connection base 4 is connected to the frame 81 through a mounting bracket 5.

[0044] The adapter 1 is used to dock with the air nozzle Q on the airbag, and a first air passage 14 for communicating with the air nozzle Q is provided inside the adapter 1.

[0045] The docking head 1 is also connected to the connection base 4 through a connecting pipe 3, and a first elastic member k1 is sleeved outside the connecting pipe 3 and located between the docking head 1 and the connection base 4.

[0046] The connecting pipe 3 supports the dynamic change of the distance between the docking head 1 and the connection base 4.

[0047] With the help of the first elastic member k1, the docking head 1 can approach the connection base 4 along the first direction F with damping.

[0048] A third air passage 43 is provided inside the connection base 4, and the connecting pipe 3 connects the first air passage 14 and the third air passage 43.

[0049] An air pipe joint 70 communicating with the third air passage 43 is provided outside the connection base 4, and the air pipe joint 70 is used to receive or discharge air flow.

[0050] In this embodiment, when it is necessary to inflate the airbag, an external air source is connected to the air pipe joint 70 on the air port connector M, and the telescopic driver 83 is started. The telescopic driver 83 drives the air port connector M to move towards the air nozzle Q through the frame 81. When the docking head 1 contacts the air nozzle Q, the frame 81 continues to move, so that the docking head 1 is tightly docked with the air nozzle Q to avoid air leakage. Then, the air flow output by the air source enters the third air passage 43 through the air pipe joint 70, and then flows into the first air passage 14, and finally enters the airbag through the docking head 1 and the air nozzle Q. Similarly, when it is necessary to deflate the airbag, the docking head 1 is also tightly docked with the air nozzle Q, and the air flow in the airbag enters the air pipe joint 70 through the air nozzle Q, the first air passage 14, and the third air passage 43, and is finally discharged through the air pipe joint 70.

[0051] During the contact process between the docking head 1 and the air nozzle Q above, due to the action of the connecting pipe 3 and the first elastic member k1, the docking head 1 moves towards the connection base 4 with damping. Thus, it can not only provide the contact pressure for the tight connection between the docking head 1 and the air nozzle Q, but also avoid the contact pressure being too large and damaging the docking head 1 and the air nozzle Q. Therefore, the error margin of the moving distance of the air port connector M is improved through the physical structure, and the requirement for the control accuracy of the telescopic driver 83 is reduced.

[0052] On the other hand, as Figures 6 to 13 , the connecting pipe 3 is connected to the connection base 4 through a connecting shaft 2. A second air passage 22 is provided inside the connecting shaft 2. With the help of the connecting pipe 3, the second air passage 22 connects the first air passage 14 and the third air passage 43. When the docking head 1 is docked with the air nozzle Q, the docking head 1 approaches the connecting shaft 2 with damping. In this embodiment, through the setting of the connecting shaft 2, the docking of the connecting pipe 3 and the connection base 4 can be conveniently realized, and the working stability of the air port connector M is effectively improved.

[0053] Further, the docking head 1 includes a first end 10 and a second end 11. The first end 10 has a receiving groove 12 for receiving and accommodating the nozzle Q. A thimble 13 for abutting against the nozzle Q is provided in the receiving groove 12. A first air passage 14 is provided in the thimble 13. The first air passage 14 extends from the receiving groove 12 to the second end 11. The first air passage 14 has a first opening 140 located in the receiving groove 12 and a second opening 141 located at the second end 11.

[0054] When the docking head 1 approaches the nozzle Q such that the nozzle Q enters the receiving groove 12, the thimble 13 in the receiving groove 12 abuts against the nozzle Q, and the air flow passage in the nozzle Q is opened by this abutting force, so that the air flow in the first air passage 14 enters the nozzle Q or the air flow in the nozzle Q is discharged into the first air passage 14.

[0055] The connecting shaft 2 includes a third end 20 and a fourth end 21. One end of the connecting pipe 3 is connected to the second end 11 of the docking head 1, the other end of the connecting pipe 3 is connected to the third end 20 of the connecting shaft 2, and the fourth end 21 of the connecting shaft 2 is connected to the connecting base 4.

[0056] Furthermore, the connecting base 4 includes a fifth end 40 and a sixth end 41. A connecting hole 42 for connecting to the fourth end 21 of the connecting shaft 2 is provided at the fifth end 40. The third air passage 43 is communicated with the second air passage 22 through the connecting hole 42.

[0057] On the other hand, the connecting pipe 3 is a flexible tube body so that the length of the connecting pipe 3 can be telescopically changed. For example, the connecting pipe 3 can be made of PE material or silicone material, and a corrugated pipe can also be used as the connecting pipe 3.

[0058] On the other hand, a transition portion 15 is further provided between the first end 10 and the second end 11. The diameters of the first end 10, the transition portion 15, and the second end 11 decrease in sequence. The second end 11 extends into the connecting pipe 3 and is hermetically connected to the inner wall of the connecting pipe 3. Since the second end 11 is also the end of the first air passage 14, placing the second end 11 into the connecting pipe 3 can effectively ensure the airtightness between the first air passage 14 and the inner cavity of the connecting pipe 3.

[0059] Further, a connecting sleeve 6 is sleeved on the outer peripheral wall of the transition portion 15. A groove 60 surrounding the connecting pipe 3 is provided at one end of the connecting sleeve 6 facing the second end 11. A boss 23 is further provided on the outer peripheral wall of the connecting shaft 2 between the third end 20 and the fourth end 21. One end of the first elastic member k1 abuts against the bottom wall of the groove 60, and the other end of the first elastic member k1 abuts against the boss 23. In this embodiment, the installation stability of the first elastic member k1 can be effectively ensured by the setting of the connecting sleeve 6.

[0060] On the other hand, the first airway 14 includes a first section 142 near the first end 10 and a second section 143 near the second end 11, and the diameter of the second section 143 is larger than that of the first section 142. Since the diameter of the second section 143 is larger than that of the first section 142, when delivering an air flow to the air nozzle Q, the air pressure of the air flow provided to the air nozzle Q can be effectively increased, thereby increasing the air delivery rate.

[0061] On the other hand, a retaining wall 52 is further provided on the mounting bracket 5. A second elastic member k2 is provided between the connecting base 4 and the retaining wall 52. The connecting base 4 is connected to the mounting bracket 5 through a second sliding mechanism. By means of the second sliding mechanism and the second elastic member k2, the connecting base 4 can approach the retaining wall 52 along the first direction F with damping. In this embodiment, during the docking process of the docking head 1 and the air nozzle Q, through the setting of the second elastic member k2, the movement margin of the docking head 1 can be further increased.

[0062] In the above embodiment, the first sliding mechanism 82 includes a first slide rail 820 and a first slider 821. The first slide rail 820 is provided on the base 80, the first slider 821 is slidably connected to the first slide rail 820, and the frame 81 is connected to the first slider 821.

[0063] The second sliding mechanism includes a second slide rail 50 and a second slider 51. The second slide rail 50 is provided on the mounting bracket 5, the second slider 51 is slidably connected to the second slide rail 50, and the second slider 51 is connected to the connecting base 4.

[0064] On the other hand, as Figure 1 and Figure 2 , an air flow transmission pipe network connected to the tracheal connector 70 is further provided on the frame 81. The tracheal connector 70 receives or discharges air flow through the air flow transmission pipe network. The air flow transmission pipe network includes an intake pipe P1, an exhaust pipe P2, and a pressure relief pipe P3.

[0065] Specifically, the intake pipe P1, the exhaust pipe P2, and the pressure relief pipe P3 are connected to the tracheal connector 70 on the air port connector M through a gas shunt row 84. High-pressure air flow is provided to the air port connector M through the intake pipe P1, and the air flow received by the air port connector M from the airbag is discharged through the exhaust pipe P2. During the process of supplying air through the intake pipe P1, the air flow can also be discharged through the pressure relief pipe P3 to avoid excessive pressure inside the air port connector M.

[0066] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
