The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] In one embodiment, Figure 1 、 Figure 2 and Figure 6 As shown, a fluid joint structure is provided, including a joint body 10, a first sealing member 20 and a tension adjustment assembly 30. The joint body 10 is provided with a first accommodating cavity 110 and a second accommodating cavity 120, and the first accommodating cavity 110 is communicated with the second accommodating cavity 120; the first accommodating cavity 110 is used to communicate with the faucet 40; the first sealing member 20 is located in the first accommodating cavity 110, and the first sealing member 20 is used to seal the connection between the first accommodating cavity 110 and the faucet 40; the tension adjustment assembly 30 is fixedly arranged in the second accommodating cavity 120, and the tension adjustment assembly 30 is communicated with the first accommodating cavity 110; the tension adjustment assembly 30 is used to insert or remove the connecting pipe 50, and adjust the tension of the inserted or removed connecting pipe 50.

[0048] The water nozzle 40 refers to the water nozzle 40 installed on the liquid cooling plate. The liquid cooling plate can be used to regulate the temperature of one side of the battery. For example, the liquid cooling plate can be installed on the bottom surface of the battery to regulate the temperature of the battery bottom surface. The battery can be a single cell or a battery can be composed of multiple cells arranged in an array. The fluid connector structure can be used to connect the water nozzle 40 of the liquid cooling plate to perform airtightness testing on the liquid cooling plate.

[0049] The connector body 10 can be made of copper, steel, or an alloy; for example, it can be made of brass. The connector body 10 can be shaped like a sleeve, for example, a copper sleeve. For example, the outer wall of the connector body 10 is provided with anti-slip grooves, which can be composed of a plurality of rectangular grooves arranged in an array. The anti-slip grooves provided on the outer wall of the connector body 10 facilitate manual disassembly and assembly of the connector body 10 by an operator. The central portion of the connector body 10 can be configured as an external hexagonal nut, making it easier for an operator to disassemble and assemble the connector body 10 using tools.

[0050] A first accommodating cavity 110 is provided at one end of the connector body 10, and a second accommodating cavity 120 is provided at the other end. The first accommodating cavity 110 and the second accommodating cavity 120 are through-cavities, with the first accommodating cavity 110 communicating with the second accommodating cavity 120. The first accommodating cavity 110 is connected to the faucet 40. For example, the first accommodating cavity 110 can be connected to the faucet 40 via a threaded or snap-on connection, thereby ensuring communication between the first accommodating cavity 110 and the faucet 40. The second accommodating cavity 120 is used to accommodate at least a portion of the tension adjustment assembly 30.

[0051] The first sealing member 20 may be a sleeve-shaped structure. The first sealing member 20 is installed and fixed in the first accommodating cavity 110 of the joint body 10. For example, the first sealing member 20 may be arranged in the first accommodating cavity 110 by means of an interference fit, so that the first sealing member 20 can fit tightly in the first accommodating cavity 110, thereby enhancing the sealing effect. Exemplarily, the first sealing member 20 may be a sealing silicone sleeve. By arranging the first sealing member 20 in the first accommodating cavity 110, when the faucet 40 is inserted into and connected to the first accommodating cavity 110 of the joint body 10, the faucet 40 can abut against the first sealing member 20, thereby achieving communication between the faucet 40 and the second accommodating cavity 120 of the joint body 10, and at the same time achieving sealing at the connection between the first accommodating cavity 110 of the first sealing member 20 and the faucet 40, thereby improving the sealing effect of the connection between the joint and the faucet 40.

[0052] The tension adjustment assembly 30 can have a hollow, through-hole structure, so that the connecting tube 50 can be inserted into the tension adjustment assembly 30 and can also be pulled out of the tension adjustment assembly 30. The tension adjustment assembly 30 can be fixedly arranged in the second accommodating chamber 120 by means of a snap connection or other means. The tension adjustment assembly 30 is connected to the first accommodating chamber 110. Then, when the connecting tube 50 is inserted into the tension adjustment assembly 30, the connecting tube 50 can be connected to the first accommodating chamber 110, and thus the connecting tube 50 is connected to the faucet 40. When the airtightness test of the liquid cooling plate is completed, the connecting tube 50 can be pulled out of the tension adjustment assembly 30. It should be noted that at least a portion of the tension adjustment assembly 30 is located outside the second accommodating chamber 120, so that the operator can operate the tension adjustment assembly 30 to adjust the tension.

[0053] Exemplarily, the connecting tube 50 can be a hose, one end of which is used to connect to the air tightness tester, and the other end of the connecting tube 50 is used to plug into the tension adjustment assembly 30. When performing an air tightness test on the liquid cooling plate, the joint body 10 is connected and fixed to the water nozzle 40 of the liquid cooling plate to achieve a sealed connection at the connection between the joint body 10 and the water nozzle 40, and the water nozzle 40 is connected to the second accommodating cavity 120 of the joint body 10; by adjusting the tension adjustment assembly 30, the tension adjustment assembly 30 is opened, and the connecting tube 50 is inserted into the tension adjustment assembly 30 so that the connecting tube 50 is connected to the water nozzle 40, and the tension adjustment assembly 30 is adjusted again so that the tension adjustment assembly 30 is locked, and then the connecting tube 50 is fastened in the tension adjustment assembly 30, and the air tightness tester is used to pump air and pressurize it, and then the gas is transmitted to the flow channel of the liquid cooling plate through the connecting tube 50 and the water nozzle 40 to perform an air tightness test on the liquid cooling plate. When the air tightness test is completed, the air tightness tester stops outputting gas, and by adjusting the tension adjustment component 30, the tension adjustment component 30 is opened, and then the connecting pipe 50 is sent to the tension adjustment component 30 and pulled out, and the joint body 10 is removed from the water nozzle 40, thereby completing the air tightness test of the corresponding liquid cooling plate.

[0054] In the above embodiment, the joint body 10 is provided with a first accommodating cavity 110 and a second accommodating cavity 120, and the first accommodating cavity 110 is communicated with the second accommodating cavity 120; the first accommodating cavity 110 is used to communicate with the faucet 40; the first sealing member 20 is located in the first accommodating cavity 110, and the first sealing member 20 is used to seal the connection between the first accommodating cavity 110 and the faucet 40; the tension adjustment component 30 is fixedly arranged in the second accommodating cavity 120, and the tension adjustment component 30 is communicated with the first accommodating cavity 110; the tension adjustment component 30 is used to insert or remove the connecting pipe 50, and adjust the tension of the inserted or removed connecting pipe 50 to achieve a sealed connection between the connecting pipe 50 and the faucet 40. In the present application, the first sealing member 20 is arranged in the first accommodating cavity 110 of the joint body 10 to seal the connection between the first accommodating cavity 110 and the water nozzle 40, thereby improving the sealing effect; the tension adjustment component 30 is arranged in the second accommodating cavity 120 of the joint body 10, and the tension adjustment component 30 is adjusted so that the connecting pipe 50 can be inserted into the tension adjustment component 30 and connected to the first accommodating cavity 110, and the connecting pipe 50 can be easily pulled out from the tension adjustment component 30, thereby strengthening the fixing strength of the connecting pipe 50, improving the sealing stability between the joint and the water nozzle 40, reducing joint leakage, and improving the air tightness test efficiency and test reliability of the liquid cooling plate, and the installation and disassembly structure is simple and easy to operate.

[0055] In one embodiment, Figure 2 and Figure 7As shown, the bottom surface of the first accommodating cavity 110 is provided with a first through boss 112 , which is communicated with the second accommodating cavity 120 ; the first sealing member 20 is provided with a first sealing sleeve 210 , which is sleeved on the outside of the first through boss 112 .

[0056] Among them, the first through-protrusion 112 and the joint body 10 are an integrally formed structure. The first through-protrusion 112 is a hollow through-protrusion structure. The first sealing sleeve 210 is a hollow through-protrusion structure. For example, the first sealing sleeve 210 can be a sealing sleeve made of TPU material and has a hardness of 90. The first sealing sleeve 210 is used to be sleeved on the outside of the first through-protrusion 112, and the first sealing sleeve 210 and the first through-protrusion 112 are interference fit, so that the first sealing sleeve 210 can fit tightly to the outer wall of the first through-protrusion 112, and the first sealing sleeve 210 can fit tightly to the bottom surface of the first accommodating cavity 110, thereby greatly increasing the sealing area, thereby increasing the sealing effect of the connection between the faucet 40 and the first through-protrusion 112.

[0057] By sleeved the first sealing sleeve 210 on the outside of the first through-penetrating boss 112, when the air tightness test of the liquid cooling plate is performed, the water nozzle 40 of the liquid cooling plate is set in the first accommodating cavity 110, and the water nozzle 40 is abutted against the end of the first sealing sleeve 210, so that the first through-penetrating boss 112 is connected to the water nozzle 40, and at the same time, the connection between the first through-penetrating boss 112 and the water nozzle 40 is sealed by the first sealing component 20, thereby improving the sealing stability between the joint and the water nozzle 40 and reducing joint leakage.

[0058] In one embodiment, Figure 3 As shown, a support platform 220 is provided at the first end of the first sealing sleeve 210, and the support platform 220 is provided with at least one limiting protrusion 222, and the bottom surface of the first accommodating cavity 110 is also provided with at least one limiting groove 114; the limiting protrusion 222 is provided in the corresponding limiting groove 114; the second end of the first sealing sleeve 210 is used to abut the water nozzle 40, so that the support platform 220 abuts the bottom surface of the first accommodating cavity 110.

[0059] The support platform 220 and the first sealing platform are integrally formed, and the support platform 220 is a hollow annular support platform 220. The support platform 220 can be arranged along the periphery of the first end of the first sealing sleeve 210. The limiting protrusions 222 are arranged in conjunction with corresponding limiting grooves 114. For example, the support platform 220 is provided with a plurality of limiting protrusions 222, each of which is spaced apart. The bottom surface of the first accommodating chamber 110 is provided with a plurality of limiting grooves 114, each of which is spaced apart, and each limiting protrusion 222 is provided in a one-to-one correspondence with each limiting groove 114.

[0060] By fitting the first sealing sleeve 210 onto the outside of the first through-protrusion 112 and aligning the limiting protrusion 222 with the corresponding limiting groove 114, the limiting protrusion 222 is engaged with the corresponding limiting groove 114, thereby achieving the first sealing member 20 being engaged with the first accommodating cavity 110. When performing an airtightness test on the liquid cooling plate, the water nozzle 40 of the liquid cooling plate is placed in the first accommodating cavity 110, and the water nozzle 40 abuts the second end of the first sealing sleeve 210. The first through-protrusion 112 is in communication with the water nozzle 40, and the first end of the first sealing sleeve 210 abuts the bottom surface of the first accommodating cavity 110. This seals the connection between the first through-protrusion 112 and the water nozzle 40, thereby increasing the sealing area, thereby improving the sealing stability between the joint and the water nozzle 40, and reducing joint leakage.

[0061] In one embodiment, Figure 7 As shown, a preset angle is formed between the first sealing sleeve 210 and the supporting platform 220 , and the diameter of the first end portion of the first sealing sleeve 210 is greater than the diameter of the second end portion.

[0062] The first sealing sleeve 210 and the support platform 220 are combined to form a convex sealing member. A predetermined angle is formed between the first sealing sleeve 210 and the support platform 220. For example, the predetermined angle can range from 75° to 85°. This allows the diameter of the first end of the first sealing sleeve 210 to be greater than the diameter of the second end, thereby facilitating the insertion of the first sealing sleeve 210 outside the first through-protrusion 112. Exemplarily, the first through-protrusion 112 has a first end and a second end. The diameter of the first end of the first through-protrusion 112 is smaller than the diameter of the second end of the first through-protrusion 112. The second end of the first through-protrusion 112 is adjacent to the bottom surface of the first accommodating cavity 110.

[0063] By inserting the first sealing sleeve 210 outside the first through boss 112, the contact area between the first sealing sleeve 210 and the first through boss 112 can be increased, thereby preventing the first sealing sleeve 210 from being deformed. When the faucet 40 is arranged in the first accommodating cavity 110 and the faucet 40 is tightly connected to the first through boss 112, the second end of the first sealing sleeve 210 contacts the faucet 40 to achieve a better sealing effect. Compared with the traditional flat gasket sealing method, the first sealing component 20 of the present application has a larger sealing amount.

[0064] In one embodiment, Figure 4 and Figure 5As shown, the tension adjustment assembly 30 includes a retaining spring 310, a guide sleeve 320 and a release 330; the guide sleeve 320 is fixedly arranged in the second accommodating cavity 120, the guide sleeve 320 is provided with a guide channel 322, and the first end of the guide channel 322 is provided with a limiting boss 326; the first end of the release 330 is provided with a first limiting rib 332, and the second end of the release 330 is provided with a second limiting rib 334; the retaining spring 310 is arranged near the first limiting rib 332, and the retaining spring 310 is provided with a second limiting rib 334. , the guide sleeve 320 and the release 330 are connected; the first limiting rib 332 is used to be clamped on the limiting boss 326, so that the release 330 moves between the first limiting rib 332 and the second limiting rib 334 based on the guide channel 322; the release 330 is used to open the retaining spring 310 so that the connecting pipe 50 can be inserted or pulled out from the release 330, the guide sleeve 320 and the retaining spring 310; the release 330 is also used to loosen the retaining spring 310 so that the retaining spring 310 can clamp the connecting pipe 50.

[0065] The retaining spring 310 is an annular retaining spring 310 having a through hole. When the retaining spring 310 is stressed, the diameter of the through hole increases, thereby facilitating the passage of the connecting tube 50 through the retaining spring 310. When the retaining spring 310 is relaxed, the diameter of the through hole decreases, thereby clamping the connecting tube 50 and securing the connection. The guide sleeve 320 is a hollow, through-hole structure and is used to limit the release 330, allowing the release 330 to move relative to the guide sleeve 320.

[0066] The guide sleeve 320 can be fixedly mounted within the second accommodating cavity 120 by means of a snap-fit connection or other means. The guide sleeve 320 is provided with a guide channel 322, which can be hollow and cylindrical in shape. The guide channel 322 has a first end and a second end. A limiting boss 326 is provided at the first end of the guide channel 322. The limiting boss 326 is an annular limiting boss 326. The limiting boss 326 is configured to engage with the first limiting rib 332 of the release 330.

[0067] The trip 330 has a hollow, through-hole structure and has a first end and a second end. A first limiting rib 332 is provided on the first end of the trip 330. The first limiting rib 332 may have a conical structure. When assembling the tension adjustment assembly 30, the first limiting rib 332 of the trip 330 can be inserted from the second end of the guide channel 322 and be retained on the limiting boss 326. A second limiting rib 334 is provided on the second end of the trip 330. The second limiting rib 334 may have a ring-shaped structure. This facilitates an operator pressing the second limiting rib 334, causing the trip 330 to move along the second end of the guide channel 322 toward the first end until the second limiting rib 334 abuts the second end of the guide channel 322, thereby guiding and limiting the movement of the trip 330.

[0068] By placing the clamping spring 310 close to the first limiting rib 332, the clamping spring 310, the guide sleeve 320 and the release 330 are connected. When the air tightness test of the liquid cooling plate is performed, the joint body 10 is connected and fixed to the water nozzle 40 of the liquid cooling plate, and the water nozzle 40 is connected to the second accommodating cavity 120 of the joint body 10; by pressing the second limiting rib 334 of the release 330, the first limiting rib 332 of the release 330 abuts against the clamping spring 310 until the clamping spring 310 is stretched open. 0, and then pass the connecting pipe 50 through the trip 330, the guide sleeve 320 and the retaining spring 310, so that the connecting pipe 50 is connected to the water nozzle 40; the operator loosens the second limiting rib 334 of the trip 330, so that the retaining spring 310 is loosened, and the retaining spring 310 clamps the connecting pipe 50, thereby achieving the connection and fixation of the connecting pipe 50, and then pumps air and pressurizes it through the air tightness tester, and then the gas is transmitted through the connecting pipe 50 and the water nozzle 40 to the flow channel of the liquid cooling plate to perform an air tightness test on the liquid cooling plate. When the air tightness test is completed, the air tightness tester stops outputting gas, and by pressing the second limiting rib 334 of the release 330 again, the retaining spring 310 is expanded, and then the connecting pipe 50 is separated from the retaining spring 310, so that the connecting pipe 50 can be pulled out from the retaining spring 310, the guide sleeve 320 and the release 330, and the joint body 10 is removed from the water nozzle 40, thereby completing the air tightness test of the corresponding liquid cooling plate, improving the sealing stability between the joint and the water nozzle 40, reducing joint leakage, and improving the air tightness test efficiency and test reliability of the liquid cooling plate, and the installation and disassembly structure is simple and easy to operate.

[0069] For example, the connecting tube 50 is inserted into the tension adjustment assembly 30. Since the connecting tube 50 itself is elastic, when it is inserted into the bottom surface of the second accommodating cavity 120, it is restricted and stuck by the friction force of the bottom surface structure of the second accommodating cavity 120. After the operator releases the release 330, the connecting tube 50 is clamped by the retaining spring 310, thereby achieving the tightening of the connecting tube 50 and effectively preventing the connecting tube 50 from being blown open by the action of air pressure.

[0070] In one embodiment, Figure 4 、 Figure 5 and Figure 8 As shown, the tension adjustment assembly 30 further includes a limiting ring 340 ; the first end of the limiting ring 340 is disposed in the guide sleeve 320 , and the first end of the limiting ring 340 is disposed adjacent to the retaining spring 310 .

[0071] The limiting ring 340 is a hollow through structure, and is used to limit the retaining spring 310 .

[0072] The first end of the limiting ring 340 can be set in the guide sleeve 320 by an interference fit. For example, the first end of the limiting ring 340 abuts against the outer frame of the retaining spring 310, thereby limiting the retaining spring 310 between the limiting ring 340 and the first limiting rib 332 of the release 330. When the second limiting rib 334 of the release 330 is pressed, the retaining spring 310 is stretched open by the first limiting rib 332 of the release 330 to facilitate the insertion or removal of the connecting tube 50.

[0073] In one embodiment, Figure 4 and Figure 5 As shown, the tension adjustment assembly 30 also includes a second sealing member 350; the second end of the limiting ring 340 is provided with a first locking position 342; the first end of the second sealing member 350 is provided with a second locking position 352, and the second sealing member 350 is locked in the first locking position 342 of the limiting ring 340 through the second locking position 352.

[0074] The second sealing member 350 may be a silicone sealing ring. The second engaging portion 352 may be an annular groove, for example, an annular groove provided on the outer wall of the first end of the second sealing member 350. The first engaging portion 342 may be an annular rib, for example, an annular rib provided on the inner wall of the second end of the retaining ring 340.

[0075] The first end of the second sealing member 350 is inserted into the second end of the retaining ring 340, and the second retaining portion 352 is engaged with the first retaining portion 342, thereby achieving connection between the second sealing member 350 and the retaining ring 340. For example, an annular boss is provided in the second accommodating cavity 120, and the second end of the second sealing member 350 abuts against the annular boss of the second accommodating cavity 120, thereby achieving a fixed connection of the second sealing member 350 and sealing the connection between the connecting tube 50 and the bottom surface of the second accommodating cavity 120.

[0076] In one embodiment, Figure 4 and Figure 5 As shown, the outer wall of the guide sleeve 320 is provided with a plurality of first limiting members 324 , and the inner wall of the second accommodating cavity 120 is provided with a plurality of second limiting members 122 ; each first limiting member 324 is provided in a one-to-one correspondence with each second limiting member 122 .

[0077] The first limiting member 324 may be a protrusion, and the second limiting member 122 may be a groove.

[0078] Exemplarily, the outer wall of the guide sleeve 320 is provided with two first limit members 324, and the two first limit members 324 are arranged at intervals; the inner wall of the second accommodating cavity 120 is provided with two second limit members 122, and the two second limit members 122 are arranged at intervals. By inserting the guide sleeve 320 into the second accommodating cavity 120 and engaging the first limit member 324 with the corresponding second limit member 122, the guide sleeve 320 is fixed in the second accommodating cavity 120, thereby realizing the installation and fixation of the tension adjustment component 30.

[0079] In one embodiment, Figure 6 and Figure 9 As shown, a connector 124 is provided on the bottom surface of the second accommodating cavity 120 , and the connector 124 is communicated with the first accommodating cavity 110 ; the connector 124 is used for plugging the connecting pipe 50 .

[0080] The connector 124 is a hollow through-structure, communicating with the first accommodating cavity 110. For example, the connector 124 communicates with the first through-protrusion 112. The connector 124 may be conical, so that the connecting pipe 50 can be plugged into the connector 124 to connect the connecting pipe 50 to the faucet 40.

[0081] When the air tightness test of the liquid cooling plate is performed, the joint body 10 is connected and fixed to the water nozzle 40 of the liquid cooling plate, and the water nozzle 40 is connected to the second accommodating chamber 120 of the joint body 10; by pressing the second limiting rib 334 of the tripping buckle 330, the first limiting rib 332 of the tripping buckle 330 abuts against the retaining spring 310 until the retaining spring 310 is stretched open, and then the connecting pipe 50 is passed through the tripping buckle 330, the guide sleeve 320, the retaining spring 310, the limiting ring 340 and the second sealing member 350 until the connecting pipe 50 is connected to the connecting head 124, and the connecting pipe 50 is clamped to the connecting head 124 by its own friction force; when the second limiting rib 334 of the tripping buckle 330 is loosened, the contact surface of the second sealing member 350 and the retaining spring 310 will clamp the connecting pipe 50, thereby fixing the connecting pipe 50 and sealing the connection between the connecting head 124 and the connecting pipe 50. The air tightness tester is used to pump air and pressurize the air, and then the gas is transmitted to the flow channel of the liquid cooling plate through the connecting pipe 50 and the water nozzle 40 to perform an air tightness test on the liquid cooling plate. When the air tightness test is completed, the air tightness tester stops outputting gas and presses the second limiting rib 334 of the release 330 again to expand the retaining spring 310, thereby separating the connecting pipe 50 from the retaining spring 310, so that the connecting pipe 50 can be pulled out from the connector 124, the second sealing member 350, the limiting ring 340, the retaining spring 310, the guide sleeve 320 and the release 330, and the connector body 10 can be removed from the water nozzle 40, thereby completing the air tightness test of the corresponding liquid cooling plate, improving the sealing stability between the connector and the water nozzle 40, reducing joint leakage, and improving the efficiency and reliability of the air tightness test of the liquid cooling plate. In addition, the installation and disassembly structure is simple and easy to operate.

[0082] In one embodiment, the first accommodating cavity 110 is provided with an internal thread, and the faucet 40 is provided with an external thread. The first accommodating cavity 110 is connected to the external thread of the faucet 40 via the internal thread.

[0083] Among them, the inner wall of the first accommodating cavity 110 is provided with an internal thread, and the outer wall of the water nozzle 40 is provided with an external thread. By rotating the joint body 10, the internal thread of the first accommodating cavity 110 is matched with the external thread of the water nozzle 40 to connect, thereby realizing the connection between the joint body 10 and the water nozzle 40, thereby improving the convenience of disassembly and assembly of the joint body 10.

[0084] In one embodiment, an air tightness testing system is further provided, comprising an air tightness tester, a connecting pipe, and a fluid joint structure as described above; the connecting pipe is connected between the air tightness tester and the fluid joint structure.

The tension adjustment assembly is used to insert or remove the connecting pipe, and adjust the tightness of the inserted or removed connecting pipe to achieve a sealed connection between the connecting pipe and the water nozzle.

[0087] In the above-mentioned embodiment, the first sealing member is arranged in the first accommodating cavity of the joint body to seal the connection between the first accommodating cavity and the water nozzle, thereby improving the sealing effect; the tension adjustment component is arranged in the second accommodating cavity of the joint body, and the tension adjustment component is adjusted so that the connecting pipe can be inserted into the tension adjustment component and connected to the first accommodating cavity, and the connecting pipe can be easily pulled out from the tension adjustment component, thereby enhancing the fixing strength of the connecting pipe, improving the sealing stability between the joint and the water nozzle, reducing joint leakage, and improving the air tightness test efficiency and test reliability of the liquid cooling plate, and the installation and disassembly structure is simple and easy to operate.

[0088] It should be noted that the air tightness test system may also include components such as a display, and the specific electrical tightness test system may include more components than those described in the above embodiments, or combine certain components, or have a different component arrangement.
