Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0059] Currently, testing the airtightness of cooling elements (such as water-cooling plates) is an important process in the production of battery modules.

[0060] To inflate the interior of a cooling element through its connecting port, a plugging mechanism of a plugging device in an airtightness testing device is typically plugged into the connecting port. Because there may be relative positional errors between the connecting port and the plugging mechanism, side leakage or even damage to the plugging mechanism can occur during plugging.

[0061] In order to alleviate, mitigate or eliminate the risk of side leakage and the problem of easy damage to the plugging mechanism when the plugging mechanism of the plugging device of the airtightness testing equipment is plugged into the connecting port of the cooling element, a first floating adjustment assembly can be configured to be connected to the first floating element, thereby driving the first guide member and the second guide member provided on the first floating element for receiving one end of the cooling element in the second direction to adjust the position along the first direction. This design makes it possible to use the outer shape of the cooling element as a guide and use the first floating adjustment mechanism for rough positioning along the first direction, thereby allowing automatic correction along the first direction.

[0062] Based on the above considerations, a floating plug-in device for a cooling part is designed. By setting the first floating adjustment component to be connected to the first floating part, the risk of side leakage and the problem of easy damage to the plugging mechanism when the plugging mechanism of the plug-in device of the air tightness detection equipment is plugged into the connecting port of the cooling part are alleviated, reduced or eliminated.

[0063] The floating plug-in device disclosed in the embodiment of the present application can be used to detect the air tightness of a battery cooling element (e.g., a water-cooled plate). An air tightness detection device equipped with the floating plug-in device disclosed in the present application can be used.

[0064] Refer to Figure 1 and further to Figures 2 and 3. Figure 1 is a schematic diagram of the structure of a floating interlocking device 100 according to some embodiments of the present application; Figure 2 is a schematic diagram of the structure of the floating interlocking device 100 in conjunction with a cooling element 200 according to some embodiments of the present application; and Figure 3 is a schematic diagram of the structure of the floating interlocking device 100 from another angle according to some embodiments of the present application. The floating interlocking device 100 is applied to the cooling element 200. The floating interlocking device 100 includes a guide assembly and a first floating adjustment mechanism. The guide assembly includes a first guide member 110 and a second guide member 120. The first guide member 110 and the second guide member 120 are disposed opposite each other in a first direction X, and are configured to receive one end of the cooling element 200 in a second direction Y and to position the communication port of the cooling element 200. The second direction Y intersects the first direction X. The first floating adjustment mechanism includes a first floating member 130 and a first floating adjustment assembly 140. The first floating member 130 extends along the first direction X, and the first guide member 110 and the second guide member 120 are disposed at opposite ends of the first floating member 130 in the first direction X. In addition, the first floating adjustment assembly 140 is connected to the first floating member 130 and is used to drive the first floating member 130 to adjust its position along the first direction X.

[0065] As shown in the figure, the first direction X is the width direction of the cooling member 200, and the second direction Y is the length direction of the cooling member 200.

[0066] As shown in Figures 1 to 3, in order to locate the position of the communication port of the cooling member 200, a first guide member 110 and a second guide member 120 are provided at both ends of the first floating member 130. In the example shown in Figures 1 to 3, the first floating member 130 is connected to the first guide member 110 and the second guide member 120 via some plates. In some embodiments, the first guide member 110 and the second guide member 120 can also be directly mounted on both ends of the first floating member 130. In the example shown in Figures 1 to 3, the first guide member 110 and / or the second guide member 120 can also swing about a vertical axis to better accommodate the cooling member 200.

[0067] 2 , the first guide 110 and the second guide 120 can jointly receive one end of the cooling member 200 in the second direction Y. Specifically, the first guide 110 contacts one side and end surface of the cooling member 200 , and the second guide 120 contacts the other side and end surface of the cooling member 200 .

[0068] By connecting the first floating adjustment assembly to the first floating member, the first and second guide members, which are mounted on the first floating member and receive one end of the cooling element in the second direction, can be adjusted along the first direction. This design allows the first floating adjustment mechanism to perform rough positioning along the first direction X, utilizing the cooling element's outer shape as a guide. This allows for automatic correction along the first direction X. This helps mitigate the risk of side leakage caused by plug-in coupling and the vulnerability of the plugging mechanism to damage, thereby improving the reliability of the coupling.

[0069] Please continue to refer to Figures 1 to 3. According to some embodiments of the present application, the first floating adjustment assembly 140 includes a first guide rail 150 extending along a first direction X and a first slide 160 slidably engaged with the first guide rail 150. One of the first guide rail 150 and the first slide 160 is configured to be fixedly connected to the first floating member 130.

[0070] In the example shown in FIG3 , the first slide 160 is mounted on the lower portion of the first floating member 130, and the first guide rail 150 is mounted on the second floating member 180. However, it is understood that the first guide rail 150 may also be mounted on the lower portion of the first floating member 130, and the first slide 160 mounted on the second floating member 180, as long as the first slide 160 can slide on the first guide rail 150, and this disclosure is not limited thereto.

[0071] By providing a first slide and a first guide rail that slide in cooperation with each other, the first floating member can be adjusted in position along the first direction X. Thus, the first guide member and the second guide member can be roughly positioned along the first direction X using the outer shape of the cooling member as a guide.

[0072] According to some embodiments of the present application, the first floating adjustment assembly 140 further includes a first elastic member 170. The first elastic member 170 is disposed on the first floating member 130 and is configured to apply an elastic force to return the first floating member 130 when the first floating member 130 slides on the first guide rail 150 via the first slide 160.

[0073] In the example shown in Figure 1, since the first guide member and the second guide member are roughly positioned along the first direction X, the first floating member 130 may move in the positive direction (i.e., to the right) along the first direction X. At this time, the first elastic member 170 applies an elastic force to the first floating member 130 to return to the left.

[0074] Herein, the term “forward direction” refers to the direction of the arrow along the axis of the coordinate system in the figure, and the term “reverse direction” refers to the direction of the arrow against the axis of the coordinate system in the figure.

[0075] According to some embodiments of the present application, the first elastic member 170 may include a spring plunger, but it is understood that the first elastic member 170 may also include a coil spring, which is not limited in the present disclosure.

[0076] By providing the first elastic member, the elastic force of the first elastic member can be used to drive the first floating member to reset.

[0077] According to some embodiments of the present application, the floating docking device 100 may further include a second floating adjustment mechanism. This second floating adjustment mechanism includes a second floating member 180 and a second floating adjustment assembly 190. The other of the first guide rail 150 and the first slide 160 is disposed on the second floating member 180. The second floating adjustment assembly 190 is connected to the second floating member 180 and is configured to drive the second floating member 180 to adjust its position along the second direction Y.

[0078] In the example shown in FIG1 , the second floating member 180 is composed of two separate L-shaped components. In some embodiments, the second floating member 180 may also be an integrated component.

[0079] This design allows for coarse positioning in the second direction Y using the cooling element's outer shape as a guide and the second floating adjustment mechanism. This allows for automatic correction in the second direction Y. This helps mitigate the risk of side leakage caused by plugging in and the issue of easy damage to the plugging mechanism, thereby improving plugging reliability.

[0080] Continuing with FIG. 1 , in some embodiments, the second floating adjustment assembly 190 may include a second guide rail 210 and a second slide 220 . The second guide rail 210 extends along the second direction Y. The second slide 220 slidably engages with the second guide rail 210 . One of the second guide rail 210 and the second slide 220 is configured to be fixedly connected to the second floating member 180 .

[0081] In the example shown in FIG1 , the second slide 220 is mounted on the lower portion of the second floating member 180, and the second guide rail 210 is mounted on the first movable member 300. However, it is understood that the second guide rail 210 may also be mounted on the lower portion of the second floating member 180, and the second slide 220 may be mounted on the first movable member 300, as long as the second slide 220 can slide on the second guide rail 210, and this disclosure is not limited thereto.

[0082] By providing a second slide and a second guide rail that slide in cooperation with each other, the second floating member can be adjusted in position along the second direction Y. Thus, the first guide member and the second guide member can be roughly positioned along the second direction Y using the outer shape of the cooling member as a guide.

[0083] 1 , the second floating adjustment assembly 190 may further include a second elastic member 230 .

[0084] In the example shown in Figure 1, since the first guide member and the second guide member are roughly positioned along the second direction Y, the second floating member 180 may move in the opposite direction (i.e., backward) along the second direction Y. At this time, the second elastic member 230 applies a forward (i.e., positive direction along the second direction Y) return elastic force to the second floating member 180.

[0085] According to some embodiments of the present application, the second elastic member 230 may include a spring plunger, but it is understood that the second elastic member 230 may also include a coil spring, which is not limited in the present disclosure.

[0086] By providing the second elastic member, the elastic force of the second elastic member can be used to drive the second floating member to reset.

[0087] According to some embodiments of the present application, in addition to the first guide rail 150 and the first slide 160, the first floating adjustment assembly 140 may further include a third guide rail 240 and a third slide 250.

[0090] 1 , the first floating adjustment assembly 140 may further include a third elastic member 260. The first elastic member 170 and the third elastic member 260 are disposed on the first floating member 130 at intervals along the first direction X, and are configured to apply elastic force to return the first floating member 130 when the first floating member 130 slides on the first guide rail 150 and the third guide rail 240 via the first slide 160 and the third slide 250, respectively.

[0091] In the example shown in Figure 1, since the first guide member and the second guide member are roughly positioned along the first direction X, the first floating member 130 may move in the opposite direction (i.e., to the left) along the first direction X. At this time, the third elastic member 260 applies an elastic force to the first floating member 130 to return to the right.

[0092] According to some embodiments of the present application, the third elastic member 260 may include a spring plunger, but it is understood that the third elastic member 260 may also include a coil spring, which is not limited in the present disclosure.

[0093] By providing an additional third elastic member, the elastic force of the third elastic member can be used to drive the first floating member to reset, so that the first floating member can be subjected to the elastic force of returning when the position is adjusted in the forward or reverse direction along the first direction.

[0094] Continuing with Figure 1 , the second floating adjustment mechanism may further include a fourth guide rail 270 and a fourth slide 280.

[0098] In the example shown in Figure 1, since the first guide member and the second guide member are roughly positioned along the second direction Y, the second floating member 180 may move in the opposite direction (i.e., backward) along the second direction Y. At this time, the fourth elastic member 290 applies a forward (i.e., positive direction along the second direction Y) return elastic force to the second floating member 180.

[0099] According to some embodiments of the present application, the fourth elastic member 290 may include a spring plunger, but it is understood that the fourth elastic member 290 may also include a coil spring, which is not limited in the present disclosure.

[0103] Such a design makes it possible to utilize the first driving mechanism to drive the first movable member to translate along the second direction, which allows the first guide member and the second guide member to quickly approach the cooling member along the second direction for further subsequent coarse positioning along the first direction and the second direction.

[0104] 2 , the first movement adjustment assembly 310 may include a fifth guide rail 330 and a fifth slide 340. The fifth guide rail 330 extends along the second direction Y. The fifth slide 340 is slidably engaged with the fifth guide rail 330. One of the fifth guide rail 330 and the fifth slide 340 is used to be fixedly connected to the first moving member 300.

[0105] In the example shown in FIG2 , the fifth slide 340 is mounted on the lower portion of the first movable member 300, and the fifth guide rail 330 is mounted on the second movable member 380.
