[0046] In the description of the utility model, the description of reference terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the utility model. In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0047] The existing air tightness detection starts, the liquid cooling pipe joint is inserted into the detection joint, the detection joint is sealed with the outer wall of the liquid cooling pipe joint, after the detection is finished, the liquid cooling pipe joint is pulled out from the detection joint, the above insertion and pulling out process is easy to scratch the outer wall of the liquid cooling pipe joint. Cause the air tightness of the product is qualified in the detection process, but the air tightness of the product is unqualified in the subsequent assembly process and needs to be reworked, which reduces the efficiency and increases the cost.

[0048] By making the end faces of the liquid cooling pipe joint and the detection joint abut to realize sealing, so as to avoid the scratch of the outer wall of the liquid cooling pipe joint in the above insertion and pulling out process, however, the end face abutting detection process is easy to cause air leakage problem and affect the reliability of the detection result.

[0049] For this, please refer to Figures 1-6The embodiment of the present application provides a detection joint for detecting the sealing performance of a liquid cooling pipe joint 10. Please refer to Figure 2 and Figure 6 One end of the liquid cooling pipe joint 10 comprises a first joint end face 101 with a first through hole 102, wherein the first through hole 102 is used for medium flow.

[0050] Please refer to Figures 4-6 The detection joint comprises a plug 200 and a floating assembly.

[0051] The plug 200 has a second through hole 200a for air flow, and the plug 200 also has an abutting surface 200b surrounding the second through hole 200a. The abutting surface 200b can abut against the first joint end face 101 to make the second through hole 200a and the first through hole 102 communicate and seal.

[0052] It can be understood that the first joint end face 101 abuts on the abutting surface 200b of the plug 200, so that the second through hole 200a and the first through hole 102 communicate and seal, which is convenient for subsequent air tightness detection. Since the process does not need to contact the peripheral wall of the liquid cooling pipe joint 10, the detection process avoids scratching the peripheral wall, and since the abutting sealing is not limited by the outer diameter of the liquid cooling pipe joint 10, it can be compatible with liquid cooling pipe joints 10 of various outer diameters.

[0053] Please refer to Figure 4 、 Figure 5 The floating assembly 400 comprises a fixed part 410 and a floating part 420, and the plug 200 is arranged on the floating part 420, and the floating part 420 can be deflected relative to the fixed part 410. Wherein, generally, the floating part 420 and the fixed part 410 are approximately parallel, when the floating part 420 is deflected relative to the fixed part 410, the angle between the floating part 420 and the fixed part 410 changes.

[0054] It can be understood that since the liquid cooling pipe joint 10 generally mainly relies on its own peripheral wall to realize sealing connection. Therefore, the precision requirement of the first joint end face 101 is relatively low, and the first joint end face 101 may have a slight inclination, which affects the result of the sealing performance detection. By arranging the floating part 200 which can be deflected relative to the fixed part 410 around the axis of the plug 200, and arranging the plug 200 on the floating part 420, even if the first joint end face 101 is inclined, when the liquid cooling pipe joint 10 abuts on the abutting surface 200b of the plug 200, the plug 200 can be deflected relatively, so as to adjust the angle of the abutting surface 200b of the plug 200, so as to keep the first joint end face 101 of the liquid cooling pipe joint 10 can be sealed and abutted, and improve the accuracy of the detection result.

[0055] In some embodiments, the detection adapter comprises a shell 100, which is a structure visible outside the detection adapter, used to protect the plug 200, and the shell 100 can be in the shape of a cylinder. The shell 100 is fixed to the floating part 420. The shell 100 has a receiving cavity 100a, one end of which has an opening 100b. The plug 200 is arranged in the receiving cavity 100a, and the abutting surface 200b of the plug 200 faces the opening 100b.

[0056] In some embodiments, the radial dimension of the outer edge of the abutting surface 200b is 29-50 mm.

[0057] In some embodiments, the radial dimension of the inner edge of the abutting surface 200b is 3-10 mm.

[0058] It can be understood that the radial dimension of the inner edge of the abutting surface 200b is the size of the second through hole 200a, and if the size is too small, it will affect the air flow, thereby affecting the efficiency of the air tightness detection, and if the size is too large, it will affect the width of the abutting surface 200b. The minimum value of the radial dimension of the inner edge of the abutting surface 200b is set to 3 mm to meet the efficiency requirement of the air tightness detection. In addition, the maximum value of the radial dimension of the inner edge is set to 10 mm, and the minimum value of the radial dimension of the outer edge is set to 29 mm, so that the radial width of the abutting surface 200b is at least 19 mm. Thus, the machining tolerance and assembly tolerance can be adapted to ensure that the abutting surface 200b can abut the first adapter end surface 101 to make the second through hole 200a and the first through hole 102 communicate and seal within the above tolerances. When the size of the liquid cooling pipe adapter 10 changes due to changes in the specifications of the battery product, the detection adapter can still abut the first adapter end surface 101, thereby improving the application range of the detection adapter.

[0059] In some embodiments, the plug 200 comprises a main body part 220 and an elastically deformable elastic part 210, the elastic part 210 is connected to one end of the main body part 220, and the abutting surface 200b is the end surface of the elastic part 210 away from the main body part 220, that is, the end surface of the elastic part 210 facing the opening 100b. It can be understood that when the abutting surface 200b abuts the first adapter end surface 101, the elastic deformation of the elastic part 210 can make the abutting surface 200b better fit the first adapter end surface 101, and the sealing between the two is better, so as to ensure the accuracy of the detection result.

[0060] In some embodiments, the main body part 220 and the elastic part 210 can be detachably arranged, for example, the main body part 220 is a piston, and the elastic part 210 is an elastic sealing gasket. The elastic part 210 is arranged at the end of the piston facing the opening 100b, and the abutting surface 200b is at least part of the end surface of the elastic part 210 away from the piston.

[0061] The end face of the piston member facing the opening 100b is provided with a groove, and the sealing gasket is arranged at least partially in the groove, so that the sealing gasket is quickly positioned through the groove.

[0062] To avoid air flow passing between the outer wall of the plug 200 and the inner wall of the shell 100, the outer wall of the plug 200 and the inner wall of the shell 100 are sealingly matched. In some embodiments, the outer wall of the plug 200 is provided with a sealing groove, and a sealing ring 500 is arranged in the sealing groove, and the sealing ring 500 is elastically deformed to further realize the sealing of the outer wall of the plug 200 and the inner wall of the shell 100.

[0063] To facilitate the installation of the plug 200, in some embodiments, the shell 100 includes an end cover 110 and a shell body 120, and the opening 100b is arranged on the end cover 110. The end cover 110 and the shell body 120 are detachably connected, and the detachable connection can be a clamping connection or a threaded connection.

[0064] The end of the end cover 110 away from the shell body 120 has an inwardly protruding stop edge 111, and part of the plug 200 abuts against the stop edge 111, so that the plug 200 is constrained in the accommodation cavity 100a. Specifically, the stop edge 111 abuts against the piston member of the plug 200, and the part of the elastic portion 210 facing the opening 100b also abuts against the stop edge 111, thereby realizing the position constraint of the elastic portion 210 and the piston member.

[0065] In some embodiments, the plug 200 can slide towards or away from the opening 100b in the accommodation cavity 100a, and at this time the inner wall of the shell 100 can guide the sliding of the plug 200. Referring to Figure 5 The detection connector includes a first elastic member 300 arranged between the plug 200 and the shell 100, and the first elastic member 300 is configured to apply an action force opposite to the sliding direction to the plug 200 after the plug 200 slides relative to the shell 100.

[0066] It can be understood that when the specification of the product is changed to cause the length of the liquid cooling pipe connector 10 to change, the liquid cooling pipe connector 10 can push the plug 200 to slide inwardly during the detection process, and at this time the first elastic member 300 is elastically deformed to enable the plug 200 to still abut against and seal with the liquid cooling pipe connector 10. In this way, the detection connector can adapt to liquid cooling pipe connectors 10 of different lengths and tolerances in the length direction of the liquid cooling pipe connector 10 to maintain the above sealing effect.

[0067] The first elastic member 300 can be a spring, and in some specific embodiments, the first elastic member 300 is a compression spring. The end of the piston member away from the opening 100b is provided with a spring mounting groove, and the spring is partially mounted into the spring mounting groove and partially extends out of the spring mounting groove and abuts against the inner wall of the shell 100.

[0068] It can be understood that the connection mode of the floating assembly 400 and the shell 100 is not limited. In some embodiments, one side of the floating part 420 towards the shell 100 is formed with a clamping groove, the clamping groove of the floating part 420 can be a groove body penetrating the peripheral wall of the floating part 420, and one side of the shell 100 towards the floating assembly 400 is formed with a clamping protrusion, the clamping groove can be matched with the clamping protrusion to realize the connection of the floating assembly 400 and the shell 100. Specifically, the clamping protrusion can slide into the clamping groove from the penetration of the peripheral wall of the floating part 420, thereby limiting the movement of the floating part 420 and the fixed part 410 along the axial direction of the plug 200. A fastener is also included, which is arranged on the floating part 420 and can be abutted on the clamping protrusion of the shell 100, so as to further limit the sliding of the clamping protrusion in the clamping groove, thereby enabling the floating part 420 to be detachably fixed with the shell 100.

[0069] In some embodiments, referring to Figure 5 , Figure 6 , the floating assembly 400 includes a ball part 430 and a connecting piece 440, and along the axial direction of the plug 200, one side of the floating part 420 towards the fixed part 410 is provided with a first arc-shaped groove, one side of the fixed part 410 towards the floating part 420 is provided with a second arc-shaped groove, and the connecting piece 440 is connected to the floating part 420 and the fixed part 410 respectively and is configured to limit the mutual separation movement between the floating part 420 and the fixed part 410 along the axial direction, so as to clamp the ball part 430 in the first arc-shaped groove and the second arc-shaped groove, and one of the floating part 420 and the fixed part 410 can be deflected relative to the connecting piece 440 around the axial line of the plug 200. In this way, the ball part 430 can be supported between the floating part 420 and the fixed part 410, and when the floating part 420 is deflected relative to the fixed part 410 around the axial line of the plug 200, the groove wall of the first arc-shaped groove of the floating part 420 or the groove wall of the second arc-shaped groove of the fixed part 410 slides on the surface of the ball part 430, at this time the ball part 430 restricts the radial relative position of the floating part 420 and the fixed part 410 through the first arc-shaped groove and the second arc-shaped groove, and the stability of the three is good.

[0070] Among them, the number of connecting pieces 440 is multiple, and the connecting pieces 440 are arranged at equal intervals around the ball part 430. The connecting piece 440 can be a connecting pin.

[0071] It can be understood that during the floating process, the floating part 420 is deflected relative to the fixed part 410, and the connecting piece 440 connected to the floating part 420 and the fixed part 410 needs to move relative to the fixed part 410 or move relative to the floating part 420.

[0072] To this end, in some embodiments, the fixed part 410 is provided with a first mounting hole, the connecting member 440 is arranged through the first mounting hole, and the diameter of the portion of the connecting member 440 in the first mounting hole is smaller than the diameter of the first mounting hole. In this way, when the fixed part 410 and the floating part 420 are subjected to deflection movement, the connecting member 440 can move slightly in the first mounting hole.

[0073] In other embodiments, the floating part 420 is provided with a second mounting hole, the connecting member 440 is arranged through the second mounting hole, and the diameter of the portion of the connecting member 440 in the second mounting hole is smaller than the diameter of the second mounting hole. In this way, when the fixed part 410 and the floating part 420 are subjected to deflection movement, the connecting member 440 can move slightly in the second mounting hole.

[0074] In some embodiments, the floating assembly further comprises a second elastic member 450, the second elastic member 450 is sleeved on the connecting member 440, and the two ends of the second elastic member 450 abut against the fixed part 410 and the floating part 420 respectively. Thus, after the floating part 420 and the fixed part 410 are subjected to relative deflection, the second elastic member 450 can provide elastic force to return to the original position, so as to ensure the accuracy of the abutting position with the liquid cooling pipe joint 10 next time.

[0075] The embodiments of the present application also provide a detection device, which comprises a placing assembly, a detection joint, and a driving assembly. The placing assembly is used for placing a battery module to be detected, and the battery module has a liquid cooling pipe joint 10. The detection joint is used for cooperating with the liquid cooling pipe joint 10 to detect the air tightness of the liquid cooling system of the battery module. The driving assembly is used for driving the detection joint to move.

[0076] It can be understood that generally, the liquid cooling system of the battery module has two groups of liquid cooling pipe joints 10, one group of liquid cooling pipe joints 10 is used for flowing medium into the battery module, and the other group of liquid cooling pipe joints 10 is used for flowing medium out of the battery module. Therefore, two groups of detection joints need to be correspondingly arranged for detecting the sealing property. Since the detection process generally seals one group of liquid cooling pipe joints 10 and blows air to the other group of liquid cooling pipe joints 10 to measure the sealing property, one group of detection joints needs to seal and abut against the first joint end surface 101 of the liquid cooling pipe joint 10 by the abutting surface 200b, so as to make the second through hole 200a and the first through hole 102 communicate. The other group of detection joints needs to seal and abut against the first joint end surface 101 of the liquid cooling pipe joint 10 by the abutting surface 200b, and the second through hole 200a of the other group of detection joints is sealed. The above-mentioned arrangement of two groups of detection joints can make the shapes and sizes of the joints the same, so as to reduce the design cost.

[0077] Since the detection process is usually closed to a group of liquid cooling pipe joints 10, the corresponding joints of the closed group of liquid cooling pipe joints 10 can also not need to be provided with a second through hole 200a. That is, the corresponding joints of the liquid cooling pipe joints 10 in which the liquid cooling pipe joints 10 are in communication are selected as detection joints, and the corresponding joints of the other group of closed liquid cooling pipe joints 10 are selected as other joints, and the other joints have a bearing surface 200b, and the middle part of the bearing surface 200b is not provided with a hole.

[0078] The driving assembly is configured to drive the detection joints to move until the bearing surface 200b of the detection joints seals against the first joint end surface 101 of the liquid cooling pipe joint 10, so that the second through hole 200a and the first through hole 102 are in communication. When the number of detection joints is two groups, the driving assembly drives the two groups of detection joints to move and abut against the two groups of liquid cooling pipe joints 10, respectively, so that the first through hole 102 of one group of liquid cooling pipe joints 10 is closed, and the first through hole 102 of the other group of liquid cooling pipe joints 10 is in communication with the second through hole 200a of the corresponding detection joint and is sealed. After the detection is completed, the driving assembly drives the two groups of detection joints to return to the original position. The above-mentioned automated detection improves the detection efficiency, avoids the problem of manual missed detection, and has higher detection accuracy.

[0079] The number of detection joints in each group of detection joints can be one or more.

[0080] The two groups of detection joints can be arranged side by side.

[0081] It can be understood that when the detection result shows that there is a problem of air tightness, manual repeated detection with bubble water or helium detector is still needed to determine whether the product or the air tightness equipment has a problem. The above-mentioned re-detection process is low in efficiency.

[0082] For this purpose, please refer to Figure 1 and Figure 3 In some embodiments, the detection device further comprises a self-detection joint 20, one end of the self-detection joint 20 comprises a second joint end surface having a third through hole for medium flow.

[0083] The driving assembly is further configured to drive the detection joints to move until the bearing surface 200b of the detection joints seals against the second joint end surface of the self-detection joint, so that the third through hole and the second through hole 200a are in communication. Further, when the number of self-detection joints 20 is two groups, the driving assembly drives the two groups of detection joints to move until the bearing surface of the detection joints seals against the second joint end surface of the self-detection joint 20, so that one group of detection joints closes a group of third through holes of the self-detection joint 20, and the second through hole 200a of the other group of detection joints and the third through hole of the other group of self-detection joints 20 are in communication.

[0084] It can be understood that when the driving assembly drives the detection joint to move and abuts and seals with each liquid cooling pipe joint 10 respectively and completes detection, if the airtightness detection is unqualified, it is necessary to further confirm whether the product problem or the detection equipment problem leads to the above detection unqualified. By setting the self-checking joint 20, the detection joint and the self-checking joint 20 are matched to check whether it is a problem of the detection equipment, and if the detection result is normal, it is confirmed that the product has an airtightness problem.

[0085] The shape and size of the second joint end face of the self-checking joint 20 and the third through hole can be substantially the same as those of the liquid cooling pipe joint 10.

[0086] Please refer to Figure 3 In some embodiments, the driving assembly includes a first driving member 401 and a second driving member 402, the second driving member 402 drives the detection joint and the first driving member 401 to move to a position aligned with the liquid cooling pipe joint 10 or a position aligned with the self-checking joint 20. The first driving member 401 is used to drive the two groups of detection joints to move to abut the liquid cooling pipe joint 10 respectively, or to drive the two groups of detection joints to move to abut the self-checking joint 20 respectively. The first driving member 401 and the second driving member 402 can be air cylinders.

[0087] Specifically, when the second driving member 402 drives the detection joint and the first driving member 401 to move to a preset position, at this time, each detection joint is aligned with the corresponding liquid cooling pipe joint 10, and the axis of the detection joint is substantially coincident with the axis of the corresponding liquid cooling pipe joint 10. The first driving member 401 drives the two groups of detection joints to move along the axis of the liquid cooling pipe joint 10 to abut the liquid cooling pipe joint 10 respectively. Similarly, when the second driving member 402 drives the detection joint and the first driving member 401 to move to another preset position, each detection joint is aligned with the corresponding self-checking joint 20, and at this time, the axis of the detection joint is substantially coincident with the axis of the corresponding self-checking joint 20. The first driving member 401 drives the two groups of detection joints to move along the axis of the liquid cooling pipe joint 10 to abut the self-checking joint 20 respectively.

[0088] Please refer to Figure 3 and Figure 4 In some embodiments, the detection equipment includes a mounting seat 30, the mounting seat 30 is arranged on the driving assembly, and the detection joint is detachably arranged on the mounting seat 30. The driving assembly can drive the mounting seat 30 and the two groups of detection joints to move.

[0089] By detachably arranging the two groups of detection joints on the mounting seat 30, when the specifications of the battery product change, causing the size of the liquid cooling pipe joint 10 to change greatly, the matching with the liquid cooling pipe joint 10 can be realized by detaching the two groups of detection joints and replacing new detection joints, so that the application range of the equipment can be further improved.

[0090] In some embodiments, the distance between the two sets of detection joints is adjustable.

[0091] It can be understood that when the distance between the two sets of liquid cooling pipe joints 10 of the product changes, the distance between the two sets of detection joints also needs to be changed correspondingly. By adjusting the distance between the two sets of detection joints to correspond to the change of the distance between the two sets of liquid cooling pipe joints 10, the product can be matched, so that the application range of the detection device can be increased.

[0092] It can be understood that when the distance between the two sets of liquid cooling pipe joints 10 of the product changes, the distance between the two sets of detection joints also needs to be changed correspondingly. By adjusting the distance between the two sets of detection joints to correspond to the change of the distance between the two sets of liquid cooling pipe joints 10, the product can be matched, so that the application range of the detection device can be increased. Figure 4 In some embodiments, a plurality of waist-shaped holes are formed on the mounting seat 30, and the extension direction of the waist-shaped holes is the direction of the connecting line of the axial center lines of the two sets of detection joints. The detection joints are mounted at the waist-shaped holes. In this way, by adjusting the position of the detection joints in the extension direction of the waist-shaped holes, the distance between the two sets of detection joints can be adjusted.

[0093] In some embodiments, the distance between the two sets of self-detection joints 20 is adjustable, so that more specifications of products can be adapted. The way in which the two sets of self-detection joints 20 achieve adjustable distance can refer to the way in which the detection joints achieve adjustable distance, which will not be repeated here.

[0094] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
