Detailed implementation manners

[0055] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation of the present application.

[0056] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0057] The following will be combined with Figures 1 - 29 Describe in detail the joint device 10 according to the embodiments of the present application and the cooling system 100 having the joint device 10.

[0058] Refer to Figures 1 - 13As shown, the joint device 10 according to an embodiment of the present application includes a first joint 1 and a second joint 2. The first joint 1 includes a locking ring 13, a driving locking member 15, and a locking elastic member 14. The locking ring 13 has a locking stop surface 131, and the locking stop surface 131 is an arc surface. The locking elastic member 14 is used to apply a force to the locking ring 13 in the first direction. The second joint 2 has a convex structure 22, and the convex structure 22 has a driving surface 221 and a convex locking surface 222. The convex locking surface 222 is located on the first direction side of the driving surface 221. When the second joint 2 moves in the second direction, the driving surface 221 is used to push the driving locking member 15 to move radially outward, so as to push the locking ring 13 to move in the second direction. The locking ring 13 has a locking position where the locking stop surface 131 abuts against the driving locking member 15 to lock the driving locking member 15 to the convex locking surface 222; wherein, the first direction and the second direction are opposite directions.

[0059] Optionally, the locking elastic member 14 is a locking spring or other parts that can apply an elastic force to the locking ring 13.

[0060] In Figures 1 - 19 In the illustrated example, the first direction is the F1 direction, the second direction is the F2 direction, the F1 direction and the F2 direction are opposite directions, and both the F1 direction and the F2 direction are the axial directions of the joint device 10. The locking elastic member 14 is a locking spring and is a compression spring. The locking elastic member 14 is arranged on the F2 side of the locking ring 13. After being compressed, the locking elastic member 14 can apply a force to the locking ring 13 in the F1 direction. When the position of the locking ring 13 is not locked and the locking elastic member 14 is compressed, the locking elastic member 14 continuously applies a force to the locking ring 13 in the F1 direction, causing the locking ring 13 to move in the F1 direction. When the position of the locking ring 13 is locked and the locking elastic member 14 is compressed, the locking elastic member 14 will also continuously apply a force to the locking ring 13 in the F1 direction, causing the locking ring 13 to have a tendency to move in the F1 direction.

[0061] In some embodiments not shown in the figure, the locking elastic member 14 is a locking spring and is a tension spring. The locking elastic member 14 is arranged on the F1 side of the locking ring 13. After being stretched, the locking elastic member 14 can apply a force to the locking ring 13 in the F1 direction.

[0062] In Figures 1 - 19In the illustrated example, the convex locking surface 222 is located on the F1 side of the driving surface 221. When the second joint 2 moves in the F2 direction and the driving surface 221 contacts the driving locking member 15, as the second joint 2 continues to move in the F2 direction, the driving surface 221 can push the driving locking member 15 to move radially outward. When the driving locking member 15 moves radially outward, it can push the locking ring 13 in the F2 direction. When the driving locking member 15 pushes the locking ring 13 to move to a certain position, the driving locking member 15 disengages from the driving surface 221. At this time, the locking ring 13 loses the driving force and does not continue to move in the F2 direction. Under the elastic force of the locking elastic member 14, the locking ring 13 squeezes the driving locking member 15 in the F1 direction, causing the driving locking member 15 to move along the convex locking surface 222 under the action of the squeezing force until the locking ring 13 moves at least partially past the driving locking member 15 in the F1 direction, so that the locking locking surface 131 of the locking ring 13 abuts against the driving locking member 15, locking the driving locking member 15 to the convex locking surface 222. At this time, the locking ring 13 is in the locked position.

[0063] Figures 12 - 13 It is shown that the locking ring 13 is in the locked position. At this time, the center of the locking ring 13 is located on the F1 side of a part of the driving locking member 15, and the locking locking surface 131 of the locking ring 13 abuts against the driving locking member 15, locking the driving locking member 15 to the convex locking surface 222. In this way, the position of the convex structure 22 in the first joint 1 is locked, and the relative position between the second joint 2 and the first joint 1 is also locked, and the second joint 2 and the first joint 1 will not become loose.

[0064] For the joint device 10 according to the embodiment of the present application, the locking ring 13 is used to lock the driving locking member 15, and further lock the convex structure 22, realizing the locking of the relative position between the second joint 2 and the first joint 1. The locking ring 13 has a simple structure and a good locking effect on the driving locking member 15, which is beneficial to reducing the failure rate of the joint device 10.

[0065] In some embodiments of the present application, referring to Figures 1 - 2 、 Figures 8 - 19 as shown, the first joint 1 further includes a first valve body 11 and a housing 12. The driving locking member 15 is arranged on the first valve body 11. The first valve body 11 has a plugging cavity for the second joint 2 to be plugged into. The convex structure 22 is adapted to be plugged into the plugging cavity. The housing 12 is sleeved outside the first valve body 11. The locking ring 13 is arranged between the housing 12 and the first valve body 11. The housing 12 can move relative to the first valve body 11 in a first direction and a second direction. During the process of inserting the second joint 2 into the first joint 1 and locking the driving locking member 15 and the convex structure 22 by the locking ring 13, referring to Figures 8 - 13As shown, the position of the outer shell 12 is fixed relative to the first valve body 11. When it is necessary to release the locking of the locking ring 13 on the driving locking member 15 and the protruding structure 22 to disassemble the second joint 2 from the first joint 1, refer to Figure 14 As shown, the outer shell 12 can be moved relative to the first valve body 11 in the direction of F2, so that the outer shell 12 drives the locking ring 13 to move in the direction of F2 and cross over the driving locking member 15, separating the locking and locking surface 131 from the driving locking member 15. At this time, the second joint 2 can be disassembled from the first joint 1.

[0066] Specifically, the insertion cavity has an insertion opening, and the second joint 2 is adapted to be inserted into the insertion cavity through the insertion opening, so that the protruding structure 22 enters the insertion cavity. After the protruding structure 22 enters the insertion cavity, it can cooperate with the driving locking member 15, so that the driving surface 221 drives the driving locking member 15 to move radially outward, and the driving locking member 15 moves radially inward along the protruding locking surface 222.

[0067] It can be understood that the "movement radially outward" mentioned in this application refers to the movement in a direction perpendicular to the first direction and away from the axis of the first valve body 11. The "movement radially inward" refers to the movement in a direction perpendicular to the first direction and towards the axis of the first valve body 11.

[0068] In some embodiments of the present application, refer to Figures 1 - 2 、 Figures 8 - 19 As shown, the driving locking member 15 includes a driving body 151 and a locking body 152. The driving body 151 is located on the first direction side of the locking body 152. When the second joint 2 moves in the second direction, the driving surface 221 is used to push the driving body 151 and the locking body 152 to move radially outward. When the locking ring 13 is in the locking position, the locking ring 13 can be at least partially located on the first direction side of the locking body 152 to abut against the locking body 152. Refer to Figures 1 - 2 As shown, the driving body 151 is located on the F1 side of the locking body 152. When the second joint 2 moves in the direction of F2, the driving surface 221 is used to push the driving body 151 and the locking body 152 to move radially outward. When the locking ring 13 is in the locking position, the locking ring 13 can be at least partially located on the F1 side of the locking body 152 to abut against the locking body 152. For example Figures 12 - 13 shows the locking ring 13 in the locking position. At this time, the center of the locking ring 13 is on the F1 side of the center of the locking body 152, and the locking and locking surface 131 of the locking ring 13 abuts against the locking body 152.

[0069] In some embodiments of the present application, refer to Figures 22 - 26As shown, a first installation groove 111 and a second installation groove 112 are provided on the first valve body 11. The driving body 151 is installed in the first installation groove 111, and the locking body 152 is installed in the second installation groove 112. Optionally, the number of driving bodies 151 is multiple, such as 3, 4, 5, etc., and the first installation grooves 111 correspond to the driving bodies 151 one by one. Similarly, the number of locking bodies 152 is multiple, such as 3, 4, 5, etc., and the second installation grooves 112 correspond to the locking bodies 152 one by one.

[0070] Optionally, the number of driving bodies 151 is at least 3, and the number of locking bodies 152 is at least 3 to ensure the structural force balance and stability. In Figures 25 - 26 the example, both the first installation groove 111 and the second installation groove 112 are 4, and correspondingly, both the driving body 151 and the locking body 152 are four.

[0071] Referring to Figures 1 - 2 as shown, multiple driving bodies 151 are arranged in a row at intervals along the circumferential direction of the first valve body 11, and multiple locking bodies 152 are arranged in a row at intervals along the circumferential direction of the first valve body 11.

[0072] In some embodiments of the present application, referring to Figures 3 - 5 as shown, both the driving surface 221 and the convex locking surface 222 are inclined surfaces. The distance between the radially outer end of the driving surface 221 and the radially outer end of the convex locking surface 222 is less than the distance between the radially inner end of the driving surface 221 and the radially inner end of the convex locking surface 222, and the radially outer end of the driving surface 221 is located on the first direction side of the radially inner end of the driving surface 221, and the radially inner end of the convex locking surface 222 is located on the first direction side of the radially outer end of the convex locking surface 222. In other words, the cross-section of the driving surface 221 and the convex locking surface 222 is generally arranged in a "V" shape. In this way, when the second joint 2 moves in the F2 direction, the driving surface 221 can push the locking body 152 to gradually move outward in the radial direction. When it is necessary to release the locking of the locking ring 13 on the locking body 152 and the convex structure 22 to disassemble the second joint 2 from the first joint 1, referring to Figure 14 as shown, the housing 12 is moved relative to the first valve body 11 in the F2 direction, so that the housing 12 drives the locking ring 13 to move in the F2 direction. The locking ring 13 squeezes the locking body 152 inward in the radial direction, so that the locking body 152 moves inward in the radial direction along the convex locking surface 222. The locking ring 13 continues to move in the F2 direction and crosses over the locking body 152, so that the locking and locking surface 131 is separated from the locking body 152. At this time, the second joint 2 can be disassembled from the first joint 1.

[0073] In some embodiments of the present application, referring to Figures 3 - 5As shown, the driving surface 221 is connected to the convex locking surface 222 through a transition surface 223, and the transition surface 223 is an annular surface. When the locking body 152 moves along the transition surface 223, the radial position of the locking body 152 remains unchanged.

[0074] In some embodiments of the present application, the driving body 151 is a driving rolling body. Optionally, the driving rolling body can be a spherical driving ball or a cylindrical driving roller.

[0075] In some embodiments of the present application, the locking body 152 is a locking rolling body. Optionally, the locking rolling body can be a spherical locking ball or a cylindrical locking roller.

[0076] In some embodiments of the present application, referring to Figures 12 - 13 As shown, the driving body 151 is a driving ball, the locking body 152 is a locking ball, and the diameter of the driving ball is greater than the diameter of the locking ball. Thus, it can be ensured that when the locking ring 13 needs to lock the locking body 152 and the convex structure 22, the locking ring 13 can abut against the locking body 152 from the F1 side to the F2 direction of the locking body 152, and the locking ring 13 will not reach the F1 side of the driving body 151.

[0077] In some embodiments of the present application, the inner wall of the housing 12 is provided with a first stop structure 121 and a second stop structure 122. The first stop structure 121 is located on the first direction side of the second stop structure 122. The locking ring 13 and the locking elastic member 14 are located between the first stop structure 121 and the second stop structure 122. One end of the locking elastic member 14 abuts against the locking ring 13, and the other end directly or indirectly abuts against the first valve body 11. In Figures 1 - 19 In the example shown, the first stop structure 121 is located on the F1 side of the second stop structure 122. The locking ring 13 and the locking elastic member 14 are located between the first stop structure 121 and the second stop structure 122. The locking ring 13 can move axially (i.e., in the F1 - F2 direction) between the first stop structure 121 and the second stop structure 122. The first joint 1 further includes a positioning sleeve 16. The positioning sleeve 16 is fixedly sleeved outside the first valve body 11, and the positioning sleeve 16 is located between the first stop structure 121 and the second stop structure 122. The F1 end of the locking elastic member 14 abuts against the locking ring 13, and the F2 end of the locking elastic member 14 abuts against the positioning sleeve 16.

[0078] Optionally, referring to Figures 1 - 2 、 Figures 8 - 19 、 Figure 20As shown, the first stop structure 121 is a stepped surface formed on the inner wall of the outer shell 12, and the second stop structure 122 is a snap ring. A clamping groove 123 is formed on the inner wall of the outer shell 12, and the snap ring is clamped in the clamping groove 123 and protrudes radially from the inner wall of the outer shell 12, so as to facilitate the positioning sleeve 16 to position and limit the snap ring and prevent the outer shell 12 from detaching from the first valve body 11. At this time, the first stop structure 121 serves as an undercut feature, and the snap ring serves as a movable snap member, facilitating the installation of other components (such as the lock ring 13 and the lock elastic member 14) inside the outer shell 12.

[0079] In some alternative embodiments, the second stop structure 122 is a stepped surface formed on the inner wall of the outer shell 12.

[0080] In some alternative embodiments, the first stop structure 121 is a snap ring installed on the outer shell 12.

[0081] The first stop structure 121 and the second stop structure 122 are distributed axially outside the lock ring 13 and the positioning sleeve 16 and are used for the outer shell 12 to contact and bear force when the second joint 2 is inserted and unlocked.

[0082] In some embodiments of the present application, referring to Figures 1 - 19 As shown, the first joint 1 further includes a positioning sleeve 16.

[0086] In some embodiments, when there is a small gap between the second piston 23 and the second valve port surface 214, the second inlet / outlet 211 can also be blocked.

[0087] At least when the latch ring 13 is in the locked position, that is, when the latch ring 13 is in the Figures 12 - 13 position shown, the second piston 23 abuts against the thimble 183, the first piston 181 separates from the first valve port surface 113, the second piston 23 separates from the second valve port surface 214, and the first inlet / outlet 171 communicates with the second inlet / outlet 211; at least when the first piston 181 fits against the first valve port surface 113, the first piston 181 blocks the first valve port surface 113. At this time, the first inlet / outlet 171 is blocked, as in Figures 18 - 19 the state shown, and the first inlet / outlet 171 is isolated from the second inlet / outlet 211.

[0088] In some embodiments, when there is a small gap between the first piston 181 and the first valve port surface 113, the first inlet / outlet 171 can also be blocked.

After the second piston 23 abuts against the ejector pin 183, the second piston 23 can be separated from the second valve port surface 214, as Figures 8 - 17 shown. For example, as Figures 12 - 13 shown, when the locking ring 13 locks the locking body 152, the second piston 23 is separated from the second valve port surface 214. From the moment when the second piston 23 abuts against the ejector pin 183 until the locking ring 13 locks the locking body 152, as Figures 8 - 11 shown, the second piston 23 is also separated from the second valve port surface 214.

[0095] In some embodiments of the present application, referring to Figures 1 - 2 , Figures 8 - 19 , Figure 24 As shown, an inner sealing ring mounting groove 114 is provided on the inner wall of the first valve body 11, and the first inner sealing ring 185 is mounted in the inner sealing ring mounting groove 114. The number of the first inner sealing rings 185 can be one or more, and the number of the inner sealing ring mounting grooves 114 is the same as that of the first inner sealing rings 185.

When the second joint 2 is inserted into the first joint 1, the first inner sealing ring 185 is used to fit against the outer peripheral surface of the second valve body 21 to prevent internal leakage.

[0096] In some embodiments of the present application, referring to Figures 1 - 2 , Figures 8 - 19 As shown, a second inner sealing ring 186 is provided on the outer peripheral surface of the thimble 183.

The outer sealing ring 184 is used to fit against the outer peripheral surface of the first valve body 11 to prevent external leakage.

[0098] The joint device 10 according to the embodiments of the present application can be applied to the connection or disconnection of fluids and is a quick-connect joint. A row of locking balls (or locking rollers) and a row of driving balls (or driving rollers) are arranged inside the first joint 1 of the joint device 10, and the diameter of the driving balls is larger than that of the locking balls. The initial position of the driving balls is on the arc-shaped locking and stopping surface 131 of the locking ring 13. When the second joint 2 is inserted into the first joint 1, the driving balls move radially outward and simultaneously drive the locking ring 13 to move axially in the F2 direction. When the arc-shaped locking and stopping surface 131 of the locking ring 13 moves to the position of the locking balls, the locking balls move radially outward and continue to push the locking ring 13 to move axially in the F2 direction until the locking balls move radially to the outermost position. The locking spring pushes the locking ring 13 to reset, the locking ring 13 pushes the locking balls to reset, and the arc surface of the locking balls abuts against the arc-shaped locking and stopping surface 131 of the locking ring 13 to complete the locking action.

[0099] When the second joint 2 is inserted into the first valve body 11, the outer shell 12 remains stationary, and the driving balls push the locking ring 13, causing the locking ring 13 to move axially in the F2 direction. Continuing to insert the second joint 2, the locking balls lock the second joint 2.

[0100] When it is necessary to pull out the second joint 2, hold the side wall of the outer shell 12 and push forcefully in the F2 direction. The first stopping structure 121 on the inner wall of the outer shell 12 drives the locking ring 13 and compresses the locking spring. At this time, the locking and stopping surface 131 of the locking ring 13 leaves the locking balls, and under the elastic force of the first spring 182 and the second spring 24, the second joint 2 moves outward and is pulled out from the first valve body 11.

[0101] The main functions of the arc-shaped locking and stopping surface 131 of the locking ring 13 are arc surface driving, arc surface locking, and arc surface abutting against the locking spring to transmit elastic force to generate movement.

[0102] Figures 8 - 13 It is a schematic diagram of the process of the second joint 2 being inserted into the first joint 1.

[0103] 1. Refer to Figure 8 , when the second joint 2 is inserted into the first valve body 11 of the first joint 1 along the F2 direction, the driving surface 221 of the convex structure 22 of the second joint 2 pushes the driving body 151 to move radially outward, and through the driving body 151, the locking ring 13 is pushed to move along the F2 direction, and the locking ring 13 compresses the locking spring. At this time, the relative position relationship between the locking body 152 and the locking ring 13 is as shown in Figure 9 .

[0104] 2. During the process of inserting the second connector 2 into the first valve body 11, the outer shell 12 remains stationary. The second valve body 21 pushes the first piston 181 to move in the direction of F2. The force for inserting the second connector 2 compresses the second spring 24. The second piston 23 of the second connector 2 abuts against the ejector pin 183 of the first connector 1, and the first spring 182 is compressed.

[0105] 3. Referring to Figure 10 , when the second connector 2 continues to be inserted into the first valve body 11 of the first connector 1 in the direction of F2, the driving surface 221 of the convex structure 22 pushes the locking body 152 to move radially outward, and through the locking body 152, the locking ring 13 is pushed to continue to move in the direction of F2, and the locking ring 13 continues to compress the locking spring. At this time, the relative positional relationship between the driving body 151 and the locking ring 13 is as shown in Figure 11 .

[0106] 4. Referring to Figure 12 , when the second connector 2 continues to be inserted into the first valve body 11 of the first connector 1 in the direction of F2, the locking body 152 moves radially inward onto the convex locking surface 222 of the convex structure 22. The locking ring 13 is reset in the direction of F1 under the elastic force of the locking spring, and the locking locking surface 131 of the locking ring 13 abuts against the arc surface of the locking body 152 to lock the second connector 2. At this time, the relative positional relationship between the driving body 151 and the locking ring 13 is as shown in Figure 13 .

[0107] Figures 14 - 19 FIG. is a schematic diagram of the process of the second connector 2 withdrawing from the first connector 1.

[0108] 1. Referring to Figure 14 , the outer shell 12 moves in the direction of F2. The first stop structure 121 inside the outer shell 12 drives the locking ring 13 to move in the direction of F2 and compresses the locking spring. At this time, the locking body 152 moves radially inward under the pushing of the locking ring 13. The locking locking surface 131 of the locking ring 13 leaves the arc surface of the locking body 152, and the locking ring 13 reaches the F2 side of the locking body 152, and the locking of the second connector 2 is released. At this time, the relative positional relationship between the driving body 151 and the locking ring 13 is as shown in Figure 15 .

[0109] 2. Referring to Figures 16 - 17 , under the elastic forces of the first spring 182 and the second spring 24, the second connector 2 moves outward in the direction of F1.

[0110] 3. Referring to Figures 18 - 19 , the second connector 2 gradually withdraws from the first valve body 11.
