[0002] With the continuous development of society, people's demand for automobiles is getting higher and higher. Traditional automobiles cause serious pollution, and gradually new energy vehicles are developing faster and faster. The battery is the main source of power for new energy vehicles. During the use of new energy batteries, air leakage may occur. Therefore, during the production process, it is necessary to detect the airtightness of the battery and the battery tray to prevent short circuits caused by air leakage and water seepage. During the airtightness detection process, a quick connector is required to connect and fix the pipeline.
[0003] When the existing quick connector is docked with the pipeline, a rubber ring needs to be sleeved between the two. After connection, sealant needs to be applied at the connection to ensure the sealing performance between the two. However, when the pipeline is damaged, it is not easy to disassemble the quick connector from the pipeline, and the installation is complex through the settings of the rubber ring and the sealant. Therefore, improvement and optimization are needed.
[0004] To solve the above problems, a quick connector structure for airtightness detection of a battery tray of a new energy vehicle is proposed in this application. Content of the Utility Model
[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a quick connector structure for airtightness detection of a battery tray of a new energy vehicle. By inserting or pulling out the sliding column into or out of the positioning groove, the installation or disassembly of the quick connector and the pipeline is completed; through the mutual pressing between the quick connector and the pipeline and the expansion of the sealing airbag, the sealing performance between the quick connector and the pipeline can be good, and the operation is simple.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A quick-connector structure for airtightness detection of a battery tray of a new energy vehicle, including a quick connector. A pipe is provided on the right side of the quick connector.

A rotating sleeve threadedly connected to it is sleeved on the outer wall of the quick connector. A concave ring is provided on the rotating sleeve. A plurality of fixing mechanisms are provided on the quick connector. The fixing mechanism includes a sliding column that penetrates through the quick connector and is slidably connected to it. The sliding column abuts against the inner wall of the concave ring. A positioning groove is provided on the pipe, and the sliding column is inserted into the positioning groove and abuts against its inner wall. A fixing block is fixedly connected to the outer wall of the sliding column, and the fixing block is slidably connected to the quick connector. The fixing block is fixedly connected with two springs, and both springs are fixedly connected to the quick connector. A sealing mechanism is provided in the quick connector. The sealing mechanism includes a connecting rod fixedly connected to one of the fixing blocks. The connecting rod is slidably connected to the quick connector. The connecting rod is fixedly connected with a sliding rod. A piston cavity is provided in the quick connector. The connecting rod penetrates through the quick connector and is slidably connected to it. The bottom of the sliding rod is fixedly connected with a piston, and the piston is hermetically slidably connected to the piston cavity. A connecting pipe fixedly connected to the quick connector is penetrated through the quick connector. One end of the connecting pipe communicates with the piston cavity. A limiting groove is provided on the quick connector, and a sealing airbag is fixedly connected to the inner wall of the limiting groove. The other end of the connecting pipe penetrates through the sealing airbag and is fixedly connected to it.
[0008] Preferably, two limiting ring grooves are provided on the quick connector, and both ends of the rotating sleeve are respectively embedded in the limiting ring grooves.

[0012] Preferably, the cross section of the fixing block is rectangular.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1. First, the staff inserts the pipeline into the installation groove. At this time, one hand of the staff holds the quick connector, and the other hand holds the rotating sleeve and rotates it. By rotating the rotating sleeve, the rotating sleeve is driven to move towards the pipeline. During the movement of the rotating sleeve, the sliding column first contacts the inner wall of the concave ring. Through the cooperation of the first inclined surface and the second inclined surface, the sliding column can be driven to move towards the pipeline (during this process, the fixed block moves towards the pipeline and the spring is compressed) until the sliding column is inserted into the positioning groove, thereby making the connection between the quick connector and the pipeline stable.

[0016] 3. During the movement of the fixed block, it will drive the connecting rod, the sliding rod, and the piston to move towards the pipeline. Through the sealing setting between the piston and the piston chamber, the air in the piston chamber can be injected into the sealing airbag through the connecting pipe, causing the sealing airbag to expand. When the sliding column tightly abuts against the inner wall of the positioning groove, at this time, the sealing airbag expands just to abut against the inner wall of the pipeline under the limitation of the limiting groove. Through the sealing airbag, a further layer of sealing can be carried out between the quick connector and the pipeline, ensuring the sealing performance between the quick connector and the pipeline.
[0017] In summary, by inserting or pulling out the sliding column from the positioning groove, the installation or disassembly of the quick connector and the pipeline is completed; by tightly abutting the quick connector and the pipeline against each other and through the expansion of the sealing airbag, the sealing performance between the quick connector and the pipeline can be good, and the operation is simple.

A rotating sleeve 4 threadedly connected to the outer wall of the quick connector 1 is sleeved on the quick connector 1. Two limiting ring grooves 5 are provided on the quick connector 1, and both ends of the rotating sleeve 4 are respectively embedded in the limiting ring grooves 5. Inner threads and outer threads that cooperate with each other are respectively provided on the inner wall of the rotating sleeve 4 and the outer wall of the limiting ring groove 5.

[0023] A concave ring 7 is provided on the rotating sleeve 4. A plurality of fixing mechanisms are provided on the quick connector 1. The fixing mechanism includes a sliding column 6 that penetrates through the quick connector 1 and is slidably connected thereto. The sliding column 6 abuts against the inner wall of the concave ring 7. A first inclined surface is provided on the sliding column 6, and a second inclined surface is provided on the inner wall of the concave ring 7. The first inclined surface and the second inclined surface are in close contact. By rotating the rotating sleeve 4, the rotating sleeve 4 can move on the quick connector 1, so that the inner wall of the concave ring 7 presses the sliding column 6, and the sliding column 6 is inserted into the positioning groove 8 to complete the fixation of the pipe 2.
[0024] A positioning groove 8 is provided on the pipe 2. The sliding column 6 is inserted into the positioning groove 8 and abuts against its inner wall. A third inclined surface is provided on the sliding column 6, and a fourth inclined surface is provided on the inner wall of the positioning groove 8. The third inclined surface and the fourth inclined surface are in close contact. By pressing the inner wall of the positioning groove 8 by the sliding column 6, the pipe 2 is moved towards the direction of the quick connector 1 to connect and fix the two, and the squeezing of the quick connector 1 and the pipe 2 ensures the sealing between the two. A fixing block 9 is fixedly connected to the outer wall of the sliding column 6. The cross section of the fixing block 9 is rectangular. The fixing block 9 is slidably connected to the quick connector 1. Two springs 10 are fixedly connected to the fixing block 9, and both springs 10 are fixedly connected to the quick connector 1. The cross section of the fixing block 9 being rectangular enables the fixing block 9 to only slide.
[0025] The quick connector 1 is provided with a sealing mechanism. The sealing mechanism includes a connecting rod 11 fixedly connected to one of the fixed blocks 9. The connecting rod 11 is slidably connected to the quick connector 1. The connecting rod 11 is fixedly connected to a sliding rod 12. A piston chamber 13 is provided in the quick connector 1. The connecting rod 11 penetrates through the quick connector 1 and is slidably connected thereto. The bottom of the sliding rod 12 is fixedly connected to a piston 14.

One end of the connecting pipe 15 is communicated with the piston chamber 13. A limiting groove 17 is provided on the quick connector 1. A sealing airbag 16 is fixedly connected to the inner wall of the limiting groove 17. The other end of the connecting pipe 15 penetrates through the sealing airbag 16 and is fixedly connected thereto. The air in the piston chamber 13 is injected into the sealing airbag 16 to make it expand and abut against the inner wall of the pipeline 2. At this time, through the setting of the sealing airbag 16, the quick connector 1 and the pipeline 2 can be sealed again to ensure the airtightness of the two.
[0026] In the present utility model, when performing airtightness detection on the battery tray of a new energy vehicle, it is necessary to fixedly connect the quick connector 1 and the pipeline 2 and ensure the airtightness between the two to ensure the normal progress of subsequent detection; the staff first inserts the pipeline 2 into the installation groove 3. At this time, one hand of the staff holds the quick connector 1, and the other hand holds the rotating sleeve 4 and rotates it. By rotating the rotating sleeve 4, the rotating sleeve 4 is driven to move towards the pipeline 2. During the movement of the rotating sleeve 4, the sliding column 6 first contacts the inner wall of the concave ring 7. Through the cooperation of the first inclined surface and the second inclined surface, the sliding column 6 can be driven to move towards the pipeline 2 (during this process, the fixed block 9 moves towards the pipeline 2 and the spring 10 is compressed) until the sliding column 6 is inserted into the positioning groove 8. At this time, continue to rotate the rotating sleeve 4 until the sliding column 6 abuts against the inner wall of the positioning groove 8. Through the cooperation of the third inclined surface and the fourth inclined surface, the pipeline 2 can be driven to move towards the quick connector 1, so that the quick connector 1 and the pipeline 2 are tightly abutted, and thus the connection between the quick connector 1 and the pipeline 2 is stable. Moreover, due to the tight abutment of the quick connector 1 and the pipeline 2, the sealing effect between the quick connector 1 and the pipeline 2 is good; during the movement of the fixed block 9, the connecting rod 11, the sliding rod 12, and the piston 14 will be driven to move towards the pipeline 2. Through the sealing setting between the piston 14 and the piston chamber 13, the air in the piston chamber 13 can be injected into the sealing airbag 16 through the connecting pipe 15 to make the sealing airbag 16 expand. When the sliding column 6 tightly abuts against the inner wall of the positioning groove 8, at this time, the sealing airbag 16 expands just to abut against the inner wall of the pipeline 2 under the limitation of the limiting groove 17. Through the sealing airbag 16, the quick connector 1 and the pipeline 2 can be sealed again to ensure the sealing performance between the quick connector 1 and the pipeline 2.
