[0051] Embodiment 1

[0052] See also Figures 1 to 6As shown, the first embodiment of the present application provides a water-cooled plate assembly 2, comprising: two slide rails 21 and a water-cooled plate 22. The two slide rails 21 are arranged at intervals. The water-cooled plate 22 is located between the two slide rails 21, and the two sides of the water-cooled plate 22 are slidably connected to the corresponding slide rails 21, respectively. The water-cooled plate 22 has a connecting portion for connecting and fixing the battery pack 4, and a fluid channel is arranged in the water-cooled plate 22. The connecting portion can be a connecting hole arranged on the water-cooled plate 22, and the connecting hole can have an internal thread. The battery pack 4 can be connected to the connecting hole by a fastener, and the fastener can be a screw, and the rod of the screw passes through the battery pack 4 and is threadedly connected to the connecting hole. The water-cooled plate assembly 2 of the present application is arranged at the bottom of the battery pack 4, and there is no need to arrange a water-cooled plate inside the battery pack. Because the battery pack 4 is a sealed structure, even if water leakage occurs on the water-cooled plate 22, the leaked cooling water will not flow into the interior of the battery pack 4, thereby ensuring the safety of the battery pack 4. Furthermore, the water cooling plate 22 is an exposed structure. If the water cooling plate 22 leaks, maintenance personnel can quickly detect and find the leak and handle it, thus avoiding safety accidents caused by the leakage of the water cooling plate 22, and having higher safety.

[0053] like Figure 3 and Figure 4 As shown, the water cooling plate 22 has a main board body 221 and sliding bars 222 located on both sides of the main board body 221, and the two sliding bars 222 are respectively slidably connected to the corresponding slide rails 21, and the main board body 221 is provided with the fluid channel. The fluid channel facilitates the circulation of the cooling water. Cooling water can be injected into the fluid channel, and the cooling water can cool the battery pack 4 installed on the water cooling plate 22.

[0054] In one possible embodiment, Figure 5 and Figure 6 As shown, the slide rail 21 has a connecting plate 211 and a track bar 212 disposed on the connecting plate 211, the connecting plate 211 has a fixing hole 2113 for connection and fixing, the track bar 212 has a track groove, and the slide bar 222 is slidably connected to the track groove. The track bar 212 has a bar groove connected to the track groove, the main board body 221 is arranged to penetrate the bar groove, and the main board body 221 is used to connect the battery pack 4.

[0055] like Figure 5 and Figure 6 As shown, the track bar 212 has two strips, both of which are connected to the connecting plate 211, the track groove is formed between the two strips, and the sliding bar 222 is located between the two strips. The track groove has the function of limiting and guiding the sliding bar 222.

[0056] like Figure 3 , Figure 5 and Figure 6 As shown, the strip member includes a first strip piece 2121 and a second strip piece 2122, the first strip piece 2121 is vertically connected to the connecting plate 211, the second strip piece 2122 is connected to the first strip piece 2121, the second strip pieces 2122 of the two strip members extend toward each other, and a strip groove connected to the track groove is formed between the second strip pieces 2122 of the two strip members. The main board body 221 passes through the strip groove, and the main board body 221 is connected to the sliding bar 222.

[0057] like Figure 3 As shown, the sliding bar 222 is vertically connected to the main body 221. The sliding bar 222 is parallel to the connecting plate 211, and the two sides of the sliding bar 222 along the width direction are respectively located between the connecting plate 211 and the corresponding second strip sheet 2122. The sliding bar 222 can be a sheet structure, which can limit the position while taking up less space.

[0058] In one possible embodiment, Figure 5 and Figure 6 As shown, the track bar 212 has a first locking hole 2123, and the first locking hole 2123 is connected to the track groove. The sliding bar 222 is provided with a first elastic column 2221. When the sliding bar 222 is fully inserted into the track groove, the first elastic column 2221 is snapped into the first locking hole 2123. When the sliding bar 222 is fully inserted into the track groove, the water-cooling plate 22 is fully accommodated in the corresponding sub-cavity, and the first elastic column 2221 is snapped into the first locking hole 2123 to fix the water-cooling plate 22 and prevent it from moving, so that the battery pack 4 set in the water-cooling plate 22 can be stably set on the water-cooling plate 22, and the snap-on structure is simple and easy to operate, and there is no need to manually fix the water-cooling plate 22.

[0059] The track bar 212 has a second locking hole 2124, and the second locking hole 2124 is connected to the track groove. The sliding bar 222 is provided with a second elastic column 2222, and the water-cooling plate 22 has a push-in state and a pull-out state. In the push-in state, the sliding bar 222 is fully inserted into the track groove, and the second elastic column 2222 abuts against the inner wall of the track bar 212. In the pull-out state, the sliding bar 222 partially extends out of the track groove, and the second elastic column 2222 is clamped in the second locking hole 2124. The water-cooling plate 22 will not be completely pulled out of the track groove, and the sliding bar 222 will not completely detach from the track groove. The clamping structure is simple and easy to operate, and prevents the water-cooling plate 22 from being completely pulled out when excessive force is applied. The first locking hole 2123 and the second locking hole 2124 can be separately arranged on the upper and lower sides of the track groove.

[0060] like Figure 3 , Figure 5 and Figure 6 As shown, the connecting plate 211 is movably provided with a first elastic unlocking member 2111, and the moving direction of the first elastic unlocking member 2111 passes through the first locking hole 2123. Under the action of external force, the first elastic unlocking member 2111 can press against the first elastic column 2221, so that the first elastic column 2221 is retracted into the track groove. When the external force is removed, the first elastic unlocking member 2111 elastically resets and moves away from the first locking hole 2123. The first elastic unlocking member 2111 may include a first component 2111a and a second component 2111b, the first component 2111a is connected to the connecting plate 211, the second component 2111b is slidably connected to the first component 2111a, a spring is provided between the second component 2111b and the first component 2111a, and the spring is sleeved on the second component 2111b.

[0061] The first component 2111a has a through hole, and the second component 2111b has a cap body, a stopper and a shaft body. The cap body is connected to one end of the shaft body, and the stopper is connected to the shaft body. There is a gap between the stopper and the cap body. The shaft body passes through the through hole. The cap body and the stopper are located at both ends of the first component 2111a. The spring is sleeved on the shaft body, and one end of the spring abuts against the cap body, and the other end of the spring abuts against the first component 2111a. In the absence of external force, the elastic force of the spring makes the second component 2111b have a tendency to move downward, and the stopper abuts against the top of the first component 2111a, so that the second component 2111b will not fall out of the through hole. Under the action of external force, for example, by pressing the cap upward by hand, the end of the shaft body abuts against the first elastic column 2221, so that the first elastic column 2221 retracts into the track groove, and at this time, the spring is compressed and shortened, the water-cooling plate 22 is unlocked, and the water-cooling plate 22 can be pulled. When the external force is removed, the spring elastically recovers, driving the second component 2111b away from the first locking hole 2123. The first elastic unlocking member 2111 has a simple structure, which can make the water-cooling plate 22 very convenient to fix and unlock, saving time and effort.

[0062] In one possible embodiment, Figure 6 As shown, a second elastic unlocking member 2112 is movably provided on the cabinet 1 or the connecting plate 211, and the moving direction of the second elastic unlocking member 2112 passes through the second locking hole 2124. Under the action of external force, the second elastic unlocking member 2112 can press against the second elastic column 2222, so that the second elastic column 2222 retracts into the track groove. When the external force is removed, the second elastic unlocking member 2112 elastically resets and moves away from the second locking hole 2124. The structure of the second elastic unlocking member 2112 can be the same as that of the first elastic unlocking member 2111, the first elastic unlocking member 2111 and the second elastic unlocking member 2112 are respectively located on both sides of the slide rail along the width direction, the first locking hole 2123 is located on the strip member on the lower side of the slide rail along the width direction, and the second locking hole 2124 is located on the strip member on the upper side of the slide rail.

[0063] like Figure 6As shown, the first locking hole 2123 is provided on one of the strips, and the second locking hole 2124 is provided on the other strip. The first elastic column 2221 and the second elastic column 2222 are respectively provided on both sides of the sliding bar 222 in the width direction. If the first locking hole 2123 and the second locking hole 2124 are provided on the same side, in the process of pulling out or pushing in the water-cooling plate 22, both the first elastic unlocking member 2111 and the second elastic unlocking member 2112 need to be pressed to unlock, and this process requires two presses to unlock, which increases the difficulty of pulling out or pushing in the drawer board and makes the operation difficult. In this embodiment, the first locking hole 2123 and the second locking hole 2124 are provided on both sides of the track groove, and in the process of pulling out or pushing in the water-cooling plate 22, only the first elastic unlocking member 2111 or the second elastic unlocking member 2112 needs to be pressed once to unlock the water-cooling plate 22, and the unlocking is simple, convenient and easy to operate.
