[0090] Example 1

[0091] like Figure 1-Figure 7 As shown, this embodiment provides a battery module pressure-maintaining carrier. The battery module pressure-maintaining carrier 10 can be used to store the battery module 30 and maintain the pressure of the battery module 30 to reduce the shaking of the battery cells during transportation and ensure the operation of subsequent processes.

[0092] In some embodiments, the battery module pressure-maintaining carrier 10 has a first direction X, a second direction Y, and a third direction Z that intersect each other.

[0093] In other embodiments, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0094] In some embodiments, the battery module pressure-maintaining carrier 10 includes a base plate 110, which is used to support the battery module 30; the base plate 110 is provided with side plates 120 at both ends along the first direction X, and the side plates 120 extend along the second direction Y. When the battery module pressure-maintaining carrier 10 performs pressure-maintaining transportation on the battery module 30, the battery module 30 is placed between the two side plates 120.

[0095] In some embodiments, the battery module pressure-maintaining carrier 10 further includes a top supporting module 130 , a locking module 140 , and a pressing module 150 ; wherein the top supporting module 130 , the locking module 140 , and the pressing module 150 are each two. Specifically, the two top support modules 130 are respectively arranged on the opposite side of the side plate 120, and the top support modules 130 are connected to the bottom plate 110; the two top support modules 130 are respectively arranged on the opposite side of the side plate 120, the locking module 140 is connected to the side of the top support module 130 away from the bottom plate 110, and the top support module 130 can drive the locking module 140 to move along the third direction Z; the pressing module 150 is arranged between the two locking modules 140 and extends along the first direction X, and the two pressing modules 150 are symmetrically arranged with the first direction X as the central axis, and the pressing module 150 is used to maintain the pressure of the battery module 30, and the locking module 140 can drive the pressing module 150 to move along the second direction Y. In this way, the top support module can drive the locking module to move along the third direction, and the pressing module is arranged between the two locking modules and extends along the first direction. The locking module can drive the pressing module to move along the second direction to achieve opening and closing. When the pressing module is closed, the battery module can be pressurized, thereby avoiding excessive shaking of the battery cells during transportation and affecting the operation of subsequent processes, thereby ensuring the quality of the battery module and improving production efficiency.

[0096] In some embodiments, the top support module 130 includes a first guide rail 131 and a first slider 132, wherein the first guide rail 131 is arranged on the side plate 120 along the third direction Z; the first slider 132 is installed on the first guide rail 131, and the first slider 132 can slide along the first guide rail 131 in the third direction Z, and the locking module 140 is installed at one end of the first slider 132 away from the bottom plate 110, so that the locking module 140 can move in the third direction Z, thereby driving the pressing module 150 to move in the third direction Z, so as to achieve pressure maintenance of the battery module 30.

[0097] In some embodiments, the top support module 130 further includes a first mounting block 133 and a first elastic member 134, wherein the first mounting block 133 is connected to the first slider 132; both ends of the first elastic member 134 are connected to the first mounting block 133 and the bottom plate 110, and the first elastic member 134 pulls the first mounting block 133 close to the bottom plate 110, so that when the pressing module 150 maintains the pressure on the battery module 30, the first elastic member 134 pulls the first slider through the first mounting block 133 132 is moved along the first guide rail 131 to approach the bottom plate 110, thereby pulling the locking module 140 to approach the bottom plate 110. Since the pressing module 150 is connected to the locking module 140, the pressing module 150 is also pulled to approach the bottom plate 110. The first elastic member 134 enables the pressing module 150 to apply an elastic force to the battery module 30, thereby preventing the battery module 30 from shaking too much during transportation, and no additional drive unit is required, thereby reducing the equipment cost.

[0098] In addition, the first elastic member 134 can also prevent mechanical friction between the pressing module 150 and the battery module 30 from damaging the battery module 30 .

[0099] In some embodiments, in order to avoid excessive force exerted by the pressing module 150 on the battery module 30 under the action of the first elastic member 134 and thus damaging the battery module 30, the supporting module 130 further includes a fixing block 135 and a first buffer 136, wherein the fixing block 135 is connected to the side plate 120 and is placed between the first slider 132 and the bottom plate 110; the first buffer 136 is arranged on the fixing block 135 along the third direction Z; by providing the fixing block 135 and the first buffer 136, the travel of the first slider 132 moving close to the bottom plate 110 in the third direction Z can be limited, so that while ensuring that the pressing module 150 exerts force on the battery module 30, excessive force can be avoided and thus damaging the battery module 30; in addition, the first buffer 136 can provide a buffering effect when the first slider 132 moves close to the bottom plate 110, and slow down the instantaneous force of the pressing module 150 on the battery module 30 under the action of the first elastic member 134 to avoid damage to the battery module 30.

[0100] In some embodiments, the locking module 140 includes a support plate 141, which is connected to the top support module 130. Specifically, the support plate 141 is installed at one end of the first slider 132 away from the bottom plate 110, that is, the support plate 141 can move synchronously with the first slider 132 in the third direction Z, and the support plate 141 extends along the second direction Y.

[0101] In some embodiments, a second guide rail 142 is provided on one side of the support plate 141 close to the base plate 110, and the second guide rail 142 is along the second direction Y. A second slider 143 is movably provided on the second guide rail 142, and the second slider 143 is installed with a second mounting block 144, and the second mounting block 144 is used to install the pressing module 150; thus, under the action of the first slider 132 and the first guide rail 131, the pressing module 150 can move along the third direction Z following the entire locking module 140, and under the action of the second guide rail 142 and the second slider 143, the pressing module 150 can move along the second direction Y.

[0102] In some embodiments, in order to ensure the pressure-maintaining effect on the battery module 30, there are two second guide rails 142, which are respectively arranged on both sides of the first slider 132, and each second guide rail 142 is connected to a second slider 143, so that two pressing modules 150 symmetrically arranged with the first direction X as the central axis can be installed on the locking module 140.

[0103] In other embodiments, a limit block may be further provided at one end of the second guide rail 142 away from the first slider 132 to prevent the second slider 143 from derailing.

[0104] In some embodiments, in order to ensure that the pressing die set 150 remains in a fixed state during the pressure maintenance, the side plate 120 is provided with a guide limit groove 121, and the guide limit groove 121 includes a first groove 121a, and the first groove 121a extends along the third direction Z; the locking module 140 also includes a limit locking cylinder 145, and the limit locking cylinder 145 is arranged at one end of the second mounting block 144 close to the side plate 120, and at least a part of the limit locking cylinder 145 extends into the inner side of the first groove 121a along the first direction X, and the first elastic member 1 Under the action of 34, the limiting locking cylinder 145 always moves in the first slot 121a toward the bottom plate 110. When the pressing module 150 maintains pressure on the battery module 30, the pressing module 150 is always subjected to the force of the first elastic member 134 in the third direction Z. The extension of the first slot 121a along the third direction Z limits the displacement of the pressing module 150 in the second direction Y, thereby ensuring that the pressing module 150 is always positively pressed on the battery module 30, avoiding excessive shaking of the battery cells in the battery module 30 during transportation.

[0105] In some embodiments, in order to open the pressing module 150, the guide limit slot 121 further includes a second slot 121b, one end of the second slot 121b is connected to the first slot 121a, and the other end of the second slot 121b extends obliquely along the second direction Y; wherein the height of the second slot 121b in the third direction Z decreases as it extends away from the first slot 121a; therefore, when it is necessary to open the pressing module 150 to take and place the battery module 30, the locking module 140 is dragged and moved along the third direction Z in a direction away from the bottom plate 110, and due to the first elastic member 1 34 always applies a downward force to the locking module 140. Therefore, when the limiting locking cylinder 145 passes the intersection point of the first slot 121a and the second slot 121b, the limiting locking cylinder 145 moves along the second slot 121b under the action of the first elastic member 134, and during the movement, the height of the limiting locking cylinder 145 in the third direction Z gradually decreases as it extends away from the first slot 121a, until the limiting locking cylinder 145 moves to the lowest point of the second slot 121b, at which time the pressing module 150 is fully opened along the second direction Y and no longer moves.

[0106] On the contrary, when it is necessary to close the pressing module 150 to maintain the pressure of the battery module 30, the pressing module 150 is pushed along the second direction Y by external force, so that the limiting locking column 145 moves along the second slot 121b to the first slot 121a. When the limiting locking column 145 passes the intersection point of the first slot 121a and the second slot 121b, the limiting locking column 145 falls into the first slot 121a and is locked under the action of the first elastic member 134. At this time, the pressing module 150 is pressed against the battery module 30 to maintain the pressure.

[0107] In some embodiments, the pressing module 150 includes a connecting rod 151, which extends along the first direction X, and the end of the connecting rod 151 is connected to the second mounting block 144. Since there are two pressing modules 150, the two connecting rods 151 are symmetrically arranged with the first direction X as the central axis to ensure the pressure-maintaining effect of the pressing module 150 on the battery module 30.

[0108] In some embodiments, in order to further enhance the pressure-maintaining effect, the pressing module 150 further includes pressing columns 152, which are arranged in a matrix along a first direction X on the side of the connecting rod 151 facing the bottom plate 110. When the pressing module 150 moves along a third direction Z close to the bottom plate 110, the pressing columns 152 abut against the upper surface of the battery module 30 under the action of the first elastic member 134, thereby maintaining the pressure on the battery module 30 and reducing the shaking of the battery cells in the battery module 30 during transportation.

[0109] In some embodiments, in order to further reduce the amount of battery cell shaking during transportation of the battery module 30, the pressing module 150 also includes a second elastic member 153, both ends of which are connected to the connecting rod 151 and the pressing column 152, and the second elastic member 153 pushes the pressing column 152 along the third direction Z close to the bottom plate 110; in this way, during the pressure maintaining process, the first elastic member 134 and the second elastic member 153 act together on the pressing column 152, which can provide a larger pressure maintaining preload force on the one hand to reduce the amount of battery cell shaking, and on the other hand, can avoid mechanical friction between the pressing column 152 and the battery module 30 to ensure the quality of the battery module 30.

[0110] The battery module pressure-maintaining carrier of this embodiment can prevent the battery module from being affected in subsequent processes due to excessive shaking of the battery cells during transportation, thereby ensuring the quality of the battery module and improving production efficiency.

The opening and closing mechanism 20 is arranged at one end of the side plate 120 away from the bottom plate 110. The opening and closing mechanism 20 is used to unlock the locking module 140 to open the pressing module 150 along the second direction Y. The present embodiment arranges the opening and closing mechanism 20 to cooperate with the battery module pressure maintaining carrier 10, so as to unlock the locking module 10 to open the pressing module 150 along the second direction, so as to facilitate the taking and placing of the battery module 30. In addition, by arranging the opening and closing mechanism 20, the investment in other driving elements can be reduced, thereby reducing the equipment investment cost while ensuring production efficiency.

[0113] In some embodiments, the opening and closing mechanism 20 includes a first fixed plate 210 and a first movable plate 230 , wherein the first fixed plate 210 and the first movable plate 230 are both parallel to the bottom plate 110 , and the first movable plate 230 is disposed between the pressing die set 150 and the first fixed plate 210 .

At this time, the pressing module 150 is fully opened and no longer moves, completing the opening and closing process of the pressing module 150. At this time, the battery module 30 can be removed from the base plate 110, or the battery module 30 can be placed on the base plate 10.

[0115] In some embodiments, the opening and closing module 240 includes a third guide rail 242, a third slider 243, an opening and closing plate 244 and a second driver 241, wherein the third guide rail 242 extends along the first direction X and is arranged on the first movable plate 230; the third slider 243 is movably arranged on the third guide rail 242; the opening and closing plate 244 is connected to the third slider 243; the output end of the second driver 241 is connected to the opening and closing plate 244, and can drive the third slider 243 to slide along the third guide rail 242, so that the opening and closing plate 244 extends into and fastens the locking module 140.

[0117] In some embodiments, there are at least two third sliders 243 and they are respectively distributed on both sides of the third guide rail 242; there are at least two opening and closing plates 244 and they are respectively distributed on both sides of the third guide rail 242; the two opening and closing slot blocks 146 are respectively arranged on the opposite sides of the two support plates 141, and the opening and closing plates 244 on both sides of the third guide rail 242 face oppositely and are arranged between the two opening and closing slot blocks 146 along the first direction X; under the action of the second driver 241, the opening and closing plates 244 move toward the corresponding opening and closing slot blocks 146 and extend into and buckle the opening and closing slot blocks 146.

[0118] Thus, during the opening and closing process, the first driver 220 pushes the opening and closing module 240 to move in the third direction Z direction close to the bottom plate 110. After reaching the position, the second driver 241 pushes the opening and closing plate 244 to move in the first direction X direction close to the opening and closing slot block 146, so that at least a portion of the opening and closing plate 244 can be plugged into the opening and closing slot block 146. At this time, the first driver 220 pushes the opening and closing module 240 to move in the third direction Z direction away from the bottom plate 110, and then the locking module 140 is driven to move in the third direction Z direction away from the bottom plate 110 through the cooperation of the opening and closing plate 244 and the opening and closing slot block 146 until the limit locking cylinder 145 passes over the first After reaching the intersection of the slot 121a and the second slot 121b, the second driver 241 pushes the opening and closing plate 244 to move away from the opening and closing slot block 146 along the first direction X, so that the opening and closing plate 244 is disengaged from the opening and closing slot block 146. At this time, the limiting locking column 145 moves along the second slot 121b under the action of the first elastic member 134, and during the movement, the height of the limiting locking column 145 in the third direction Z gradually decreases as it extends away from the first slot 121a, until the limiting locking column 145 moves to the lowest point of the second slot 121b, at which time the pressing module 150 is fully opened and no longer moves.

[0119] In some embodiments, in order to ensure the overall balance and stability of the opening and closing module 240, the opening and closing mechanism 20 also includes a guide module 250, which is installed on the first fixed plate 210 along the third direction Z. One end of the guide module 250 is connected to the first movable plate 230. By setting the guide module 250, the stability of the first movable plate 230 in the third direction Z can be ensured, thereby ensuring the overall balance and stability of the opening and closing module 240.

[0120] Exemplarily, a first connecting plate is provided on the first fixed plate 210, a first linear bearing 251 is provided on the first connecting plate, and a guide module 250 is installed on the first connecting plate. Furthermore, the guide module 250 includes a first guide column 252, and the first guide column 252 is movably installed on the first linear bearing 251 along a third direction Z, and one end of the first guide column 252 is connected to the first movable plate 230; thus, by setting the guide module 250 in cooperation with the first driver 220, the balance and stability of the first movable plate 230 in the third direction Z can be ensured.

[0121] In some embodiments, there are at least two guide modules 250 , which are respectively disposed on both sides of the first driver 220 , so as to further improve the balance and stability of the first movable plate 230 moving in the third direction Z.

[0122] In some embodiments, when opening and closing, the first driver 220 pushes the opening and closing module 240 to move in the third direction Z toward the base plate 110. After the opening and closing plate 244 is plugged into the opening and closing slot block 146, the first driver 220 pushes the opening and closing module 240 to move along the third direction Z away from the base plate 110. In order to prevent the entire pressure-maintaining carrier 10 from being lifted, the opening and closing mechanism 20 also includes an anti-warping module 260. The anti-warping module 260 is installed on the first fixed plate 210 along the third direction Z. Its function is to act on the side plate 120 in the third direction Z, so as to fix the side plate 120 when the first driver 220 drives the locking module 140 to lift through the opening and closing plate 244, thereby preventing the entire pressure-maintaining carrier 10 from being lifted.

[0123] In some embodiments, a second connecting plate is disposed on the first fixing plate 210 , and the anti-warping module 260 is installed on the second connecting plate.

[0124] Specifically, the anti-warping module 260 includes a third driver 261 and an anti-warping pressure plate 264. The third driver 261 is installed on the second connecting plate, and the anti-warping pressure plate 264 is installed on the output end of the third driver 261. During the opening and closing process, the third driver 261 pushes the anti-warping pressure plate 264 to move along the third direction Z toward the bottom plate 110 until the anti-warping pressure plate 264 abuts against the side plate 120, and there is no action interference between the anti-warping module 260 and the first driver 220, the first movable plate 230 and the opening and closing module 240.

[0125] In some preferred embodiments, in order to avoid dry friction between the anti-warping pressure plate 264 and the side plate 120, a second fixed plate 262 and a second movable plate 263 are further provided between the third driver 261 and the anti-warping pressure plate 264, wherein the second fixed plate 262 is connected to the output end of the third driver 261, the anti-warping pressure plate 264 is provided on the second movable plate 263, and at least one second linear bearing 266 is provided on the second fixed plate 262, and a second guide column 267 is movably connected to the second linear bearing 266, and one end of the second guide column 267 extends along the third direction Z. The third elastic member 265 is provided between the second fixed plate 262 and the second movable plate 263, and the third elastic member 265 is sleeved on the second guide column 267; therefore, when the third driver 261 pushes the anti-warp pressure plate 264 to abut against the side plate 120, due to the joint action of the third elastic member 265 and the second guide column 267, the anti-warp pressure plate 264 has a buffering effect in the third direction Z, thereby reducing the dry friction between the anti-warp pressure plate 264 and the side plate 120, and avoiding the deformation of the side plate 120 and affecting the pressure maintaining and opening and closing effects of the equipment.

[0126] This embodiment sets an opening and closing mechanism to cooperate with the battery module pressure maintaining carrier, which can unlock the locking module to open the pressing module along the second direction, thereby facilitating the removal and placement of the battery module. By setting the opening and closing mechanism, the investment in other driving elements can be reduced, thereby reducing the equipment investment cost while ensuring production efficiency.

[0127] The working process of the present invention is:

[0128] Pressure holding process: please combine Figure 1-Figure 7 , the pressing module 150 is pushed along the second direction Y by an external force, so that the limiting locking column 145 moves along the second slot 121b to the first slot 121a. When the limiting locking column 145 passes the intersection point of the first slot 121a and the second slot 121b, the limiting locking column 145 falls into the first slot 121a and is locked under the action of the first elastic member 134. At this time, the first elastic member 134 and the second elastic member 153 act together on the pressing column 152, so that the pressing column 152 is always positively pressed on the battery module 30, thereby achieving pressure maintenance. Since the first slot 121a extends along the third direction Z, the displacement of the pressing module 150 in the second direction Y is limited, thereby preventing the battery module 30 from having excessive cell shaking during transportation;

[0129] Opening and closing process: please combine Figure 1-Figure 12 The first driver 220 pushes the opening and closing module 240 to move in the third direction Z direction close to the bottom plate 110. After reaching the position, the second driver 241 pushes the opening and closing plate 244 to move in the first direction X direction close to the opening and closing slot block 146, so that at least a portion of the opening and closing plate 244 can be inserted into the opening and closing slot block 146. Before the first driver 220 acts again, when the third driver 261 pushes the anti-warping pressure plate 264 to abut against the side plate 120 to prevent the pressure-maintaining carrier 10 from tilting, the first driver 220 then pushes the opening and closing module 240 to move in the third direction Z direction away from the bottom plate 110, and then the locking module 140 is driven to move in the third direction Z direction away from the bottom plate 110 through the cooperation of the opening and closing plate 244 and the opening and closing slot block 146 until the limit locking cylinder 14 After crossing the intersection of the first slot 121a and the second slot 121b, the second driver 241 pushes the opening and closing plate 244 to move away from the closing slot block 146 along the first direction X, so that the opening and closing plate 244 is separated from the opening and closing slot block 146. At this time, the limiting locking cylinder 145 moves along the second slot 121b under the action of the first elastic member 134, and during the movement, the height of the limiting locking cylinder 145 in the third direction Z gradually decreases as it extends away from the first slot 121a, until the limiting locking cylinder 145 moves to the lowest point of the second slot 121b, at which time the pressing module 150 is fully opened and no longer moves, and then the third driver 261 drives the anti-warping pressure plate 264 to separate from the side plate 120 along the third direction z.

[0130] In summary, the present invention provides a battery module carrier and a pressure maintaining and opening and closing device, which can avoid the problem of excessive shaking of battery cells in the battery module during transportation, so as not to affect the operation of subsequent processes, ensure the quality of the battery module, and improve production efficiency; at the same time, the lower pressure module can be opened through a special opening and closing mechanism, which is convenient for taking and placing the battery module, and by setting up the opening and closing mechanism, the investment in other driving components can be reduced, thereby reducing the equipment investment cost while ensuring production efficiency.
