The specific meaning of the above terms in the present invention can be understood as appropriate to those of ordinary skill in the art.
For a better understanding of the present invention, embodiments of the present invention are described below with reference to fig. 1 to 15.
Referring to fig. 1, an embodiment of the invention provides a cell clamp 10 that may be used to clamp a cell 99. The cell clamp 10 can clamp the cell 99 and keep the cell 99 stable in position. The cell clamp 10 includes a tray 20, a clamping assembly 30, and a lock 40. The tray 20 includes an accommodating portion 20a and a locking portion 20 b. The clamping assembly 30 is disposed in the receiving portion 20 a. The clamping assembly 30 includes at least two cell clamping plates 30a arranged side by side. Two adjacent cell clamping plates 30a may clamp one cell 99. The cell clamping plate 30a is movably attached to the tray 20. The cell clamping plate 30a is switchable between a clamping position and a releasing position when moved relative to the tray 20. The clamping position refers to the position of each of the two adjacent cell clamping plates 30a when clamping the cell 99. In the clamping position, the battery cell 99 is subjected to a clamping force by the two cell clamping plates 30a to maintain a clamped state. The release position refers to a position where the adjacent two cell clamping plates 30a are in an open state and do not apply a clamping force to the cell 99. When the cell clamping plate 30a is at the release position, the cell 99 that has been formed or soaked is in a state to be taken out. After the cell 99 that has been formed or soaked is removed, the cell 99 to be formed or soaked may be refilled. In one example, the tray 20 has a bottom wall and a linear track disposed on the bottom wall. The arrangement direction X of the cell clamping plates 30a is the same as the extension direction of the linear rails. Each of the cell clamping plates 30a is movably connected to the linear rail so as to be reciprocally movable along the linear rail.
Referring to fig. 2, the lock 40 is disposed on the outermost cell clamping plate 30 a. The lock 40 includes a slide rail 41 connected to the cell clamping plate 30a and a locking member 42 movably connected to the slide rail 41. The extending direction of the slide rail 41 intersects the arrangement direction X of the cell clamping plates 30 a. The locking member 42 has a force receiving portion 421 and a locking portion 422 connected to the force receiving portion 421. The locking part 422 of the locking member 42 is closer to the tray 20 than the force receiving part 421 of the locking member 42, that is, the force receiving part 421 is located on the side of the locking part 422 away from the tray 20. In the clamping position, the force receiving portion 421 receives an external force to drive the locking member 42 to move along the slide rail 41 as a whole, so that the locking portion 422 is locked or unlocked with the locking portion 20 b. When the cell clamping plates 30a are in the release position, a cell 99 is placed between two adjacent cell clamping plates 30 a. Then, a pushing force is applied to the outermost cell clamping plates 30a, thereby pushing the respective cell clamping plates 30a to move from the releasing position to the clamping position. When each of the cell clamping plates 30a moves to the clamping position, an external force is applied to the force receiving portion 421 of the locking member 42, so that the locking member 42 moves along the slide rail 41 toward the direction close to the tray 20, and the locking portion 422 of the locking member 42 is locked with the locking portion 20b on the tray 20, at this time, after the pushing force acting on the outermost cell clamping plate 30a is removed, the cell clamping plate 30a is restrained and limited by the locking member 42, and cannot return to the release position from the clamping position. The cell holder 10 with the battery cell 99 clamped therein may be entirely transferred to a predetermined position by a person or a related device. After the formation or infiltration process is completed, an external force is applied to the force receiving portion 421 of the locking member 42, so that the locking member 42 moves along the slide rail 41 in a direction away from the tray 20, and the locking portion 422 of the locking member 42 is unlocked from the locking portion 20b on the tray 20. At this time, the restraint on each of the cell clamping plates 30a is released, and a tensile force is applied to the outermost cell clamping plate 30a, whereby each of the cell clamping plates 30a moves from the clamping position to the releasing position. All the cells 99 can then be removed from the cell holder 10 at once by means of a gripper device.
The cell fixture 10 of the embodiment of the present invention includes a tray 20, a clamping assembly 30 for clamping the cell 99, and a lock 40 for restricting a position of the clamping assembly 30. The clamping assembly 30 includes at least two cell clamping plates 30a arranged side by side. A plurality of cells 99 can be loaded into the clamping assembly 30 at one time using the apparatus with the cell clamping plate 30a in the release position. After the formation or infiltration of the battery cells 99 is completed and the battery cell clamping plate 30a is moved from the clamping position to the releasing position, the plurality of battery cells 99 can be taken out of the clamping assembly 30 at one time by using the apparatus. Therefore, the working efficiency of clamping and transferring the battery cell 99 is effectively improved. When the cell clamping plate 30a is in the clamping position, the locking piece 42 of the lock 40 may be locked on the tray 20 to apply a constraining force to the cell clamping plate 30a, thereby ensuring that the position of the cell clamping plate 30a is kept stable, and the deviation is not easy to occur to reduce the clamping force on the cell 99. Thus, the clamping force of the cell clamping plate 30a on the cell 99 is basically kept unchanged, so that the position stability of the cell 99 is effectively ensured, and the adverse effect on the formation or infiltration effect is reduced. The battery cell clamp 10 of the embodiment of the invention clamps the battery cell 99 through the battery cell clamping plate 30a, and locks the position of the battery cell clamping plate 30a through the lock 40 of the traditional mechanical structure, so that the battery cell clamp 10 does not need to be provided with or provided with a large number of electronic elements such as electronic sensors and control units, and further, the structure of the battery cell clamp 10 is relatively simple and the reliability is high.
Referring to fig. 2, the tray 20 has a bottom wall and a side wall connected to the bottom wall. The bottom wall and the side wall enclose a receiving portion 20 a. The bottom wall is rectangular. The side wall includes two limit plates 21 and a support plate 22. The two limit plates 21 are provided at intervals in the width direction of the bottom wall. The two limiting plates 21 are respectively connected with the long edges of the bottom wall. The support plates 22 are respectively connected with the two limit plates 21 and with the wide sides of the bottom wall. The arrangement direction X of the cell clamping plates 30a is the same as the longitudinal direction of the bottom wall. The clamp assembly 30 also includes a guide rod 30b connected to the support plate 22. The guide bar 30b extends along the length of the bottom wall. Each cell clamping plate 30a is movably connected to a guide bar 30 b. The guide rod 30b plays a role in guiding and limiting the battery cell clamping plate 30a, and the battery cell clamping plate 30a is guaranteed to be stable and accurate in moving process. A spring is arranged between two adjacent cell clamping plates 30 a. The spring is sleeved on the guide rod 30 b. When the cell clamping plates 30a are switched from the releasing position to the clamping position, the adjacent two cell clamping plates 30a compress the spring. When the cell clamping plate 30a is switched from the clamping position to the release position, the spring releases elastic potential energy to additionally provide an urging force to the cell clamping plate 30 a. The locking portion 20b of the present embodiment is provided on the side wall. The slide rail 41 of the lock 40 extends in the same direction as the width of the bottom wall. The locking portion 422 of the locking member 42 is closer to the restriction plate 21 than the force receiving portion 421. When the cell clamping plate 30a is in the clamping position and the force receiving portion 421 receives an external force along the width direction of the bottom wall and toward the limit plate 21, the locking member 42 may move along the slide rail 41 toward the direction approaching the limit plate 21, so that the locking portion 422 is locked with the locking portion 20 b. When the cell clamping plate 30a is in the clamping position and the force receiving portion 421 receives an external force along the width direction of the bottom wall and away from the limiting plate 21, the locking member 42 may move along the slide rail 41 toward the limiting plate 21, so that the locking portion 422 is unlocked from the locking portion 20 b.
Referring to fig. 3, the locking member 42 is movably connected to the slide rail 41 by a force receiving portion 421. The force receiving portion 421 includes a first force receiving member 421a and a second force receiving member 421b arranged at an interval along the extending direction of the slide rail 41. The locking part 422 is connected to the first force receiving member 421 a. The second force receiving member 421b is located on a side of the first force receiving member 421a away from the locking part 422. The first force receiving member 421a receives an external force to lock the locking part 422 with the locking part 20 b. The second force receiving member 421b receives an external force to unlock the locking part 422 and the locking part 20 b. In one example, the force receiving portion 421 is a frame structure having a central relief hole 421 c. Along the extending direction of the sliding rail 41, one of two opposite frames of the force-receiving portion 421 forms a first force-receiving member 421a, and the other forms a second force-receiving member 421 b. The first and second force receiving members 421a and 421b have rectangular force receiving contact surfaces facing the center relief hole 421 c. The external force application member may protrude into the central relief hole 421c and apply a force to the first force-receiving member 421a or the second force-receiving member 421 b. Two slide rails 41 are arranged on the outermost cell clamping plate 30 a. Two opposite side frames of the force-receiving portion 421 are respectively connected to the two slide rails 41, so that the position stability of the locking member 42 during the moving process is improved.
Referring to fig. 4, the cell clamp 10 further includes a clamping portion 50 disposed on the outermost cell clamping plate 30 a. The clamping portion 50 is disposed between the first force-receiving member 421a and the second force-receiving member 421 b. The external force application device may be detachably connected to the clamping assembly 30 by a snap-in portion 50. After the external force application device is clamped by the clamping portion 50, a pulling force can be applied to the cell clamping plate 30a through the clamping portion 50 to pull the cell clamping plate 30a to move from the clamping position to the releasing position. In one example, the clamping portion 50 includes a hole 50b opened on the cell clamping plate 30a and a clamping plate 50a partially covering the hole 50 b.
Referring to fig. 4 and 5, the lock 40 further includes a stopper 43. The limiting member 43 is connected and fixed to the outermost cell clamping plate 30 a. The locking part 422 includes a latch shaft 422a connected to the force receiving part 421 and an elastic member 422 b. The locking member 42 is locked or unlocked with the locking portion 20b by the latch shaft 422 a. The elastic member 422b connects the latch shaft 422a and the stopper 43. The latch shaft 422a and the stopper 43 may compress or release the elastic member 422b in the axial direction of the latch shaft 422 a. Referring to fig. 4, when the cell clamping plate 30a is in the releasing position, the latch shaft 422a presses against the tray 20, and at this time, the latch shaft 422a and the limiting member 43 compress the elastic member 422b, so that the elastic member 422b stores elastic potential energy. Referring to fig. 5, when the cell clamping plate 30a is in the clamping position, the latch shaft 422a is inserted into the locking portion 20b of the tray 20, and at this time, the latch shaft 422a releases the elastic member 422b, so that the elastic member 422b is restored from the compressed state to the free state. When the latch shaft 422a is subjected to external stress along the axial direction of the latch shaft 422a and tends to be disengaged from the locking portion 20b, the elastic component 422b is compressed to apply resistance to the latch shaft 422a so as to counteract the external stress, reduce the possibility that the latch shaft 422a is disengaged from the locking portion 20b, and improve the connection stability and reliability of the latch shaft 422a and the locking portion 20 b. In one example, the locking portion 20b may be a through hole penetrating the tray 20. The locking portion 20b may be a blind hole that does not penetrate through the tray 20, or the locking portion 20b may be a columnar structure, and the end surface of the latch shaft 422a is provided with a blind hole that is matched with the locking portion 20 b. In one example, the latch shaft 422a extends through the retaining member 43. The latch shaft 422a has a projection. The projection extends in the circumferential direction of the latch shaft 422 a. The protrusion is located on the side of the limiting member 43 away from the force-receiving portion 421. The elastic member 422b is sleeved on the latch shaft 422a and disposed between the protrusion and the position-limiting member 43. Optionally, the limiting member 43 is a plate-shaped structure that is connected and fixed to the cell clamping plate 30 a. The elastic member 422b is a spring or a rubber sleeve.
Referring to fig. 5, the locking member 42 further includes a guide portion 423. The force receiving portion 421 is provided between the lock portion 422 and the guide portion 423 in the extending direction of the slide rail 41. When the force-bearing part 421 moves along the sliding rail 41, the guide part 423 can provide a guide for the locking member 42, further ensure that the locking member 42 keeps stable in position during moving, and reduce the possibility of the locking member 42 being stuck to the sliding rail 41 due to position deviation during moving. The guide part 423 has a guide block 423a and a guide shaft 423b movably coupled to the guide block 423 a. The guide block 423a is located on a side of the force receiving portion 421 away from the tray 20. The guide block 423a is connected to and fixed to the outermost cell clamping plate 30 a. The guide shaft 423b is connected to the force receiving portion 421. In one example, the guide block 423a has a plate-like structure having a through hole, and the guide shaft 423b is inserted into the through hole. In one example, the force receiving portion 421 includes a first force receiving member 421a and a second force receiving member 421b that are spaced apart from each other. The guide shaft 423b is connected to the second force receiving member 421 b. The guide shaft 423b is coaxially disposed with the latch shaft 422 a.
Referring to fig. 3, the lock 40 is two in number. The two lockers 40 are arranged at intervals in a direction perpendicular to the arrangement direction X. The two lockers 40 are arranged symmetrically to each other. Correspondingly, two locking portions 20b are provided on the tray 20. The two locks 40 together exert restraint on the cell clamping plate 30a of the clamping assembly 30, and can further improve the positional stability and the clamping reliability of the cell clamping plate 30a in the clamping position.
Referring to fig. 6, an embodiment of the invention further provides a cell clamping device 100, which includes the cell clamp 10 and the push-pull mechanism 200 according to the above embodiment. The push-pull mechanism 200 is used to apply a push-pull stress to the cell clamping plate 30a to switch the cell clamping plate 30a between the release position and the clamping position. The push-pull mechanism 200 can also apply a force to the force receiving portion 421 of the locking member 42 to drive the locking portion 422 of the locking member 42 to lock or unlock with the locking portion 20 b.
Referring to fig. 7, the push-pull mechanism 200 includes a push-pull member 201 and an actuating member 202 coupled to the push-pull member 201. The push-pull member 201 is detachably connected to the clamping assembly 30, so as to facilitate individual transfer of the cell fixtures 10, and meanwhile, it is realized that one push-pull mechanism 200 can be used in cooperation with a plurality of cell fixtures 10. The push-pull member 201 is used to push and pull each of the cell clamping plates 30a in the arrangement direction X of the cell clamping plates 30a between a clamping position and a releasing position. In the clamping position, the activating member 202 activates the force receiving portion 421 to apply a force to the force receiving portion 421 toward or away from the tray 20, so that the locking member 42 is driven by the force receiving portion 421 to move along the slide rail 41, so that the locking portion 422 of the locking member 42 is locked or unlocked with the locking portion 20 b. In one example, the locking member 42 is movably connected to the slide rail 41 by a force receiving portion 421. The force receiving portion 421 includes a first force receiving member 421a and a second force receiving member 421b arranged at an interval along the extending direction of the slide rail 41. The locking part 422 is connected to the first force receiving member 421 a. The second force receiving member 421b is located on a side of the first force receiving member 421a away from the locking part 422. The touch member 202 drives the locking part 422 to be locked with the locking part 20b through the first force-receiving member 421 a. The touch member 202 drives the locking portion 422 to unlock the locking portion 20b through the second force-receiving member 421 b.
Referring to fig. 8, the cell clamp 10 further includes a clamping portion 50 disposed on the outermost cell clamping plate 30 a. The clamping portion 50 is disposed between the first force-receiving member 421a and the second force-receiving member 421 b. The push-pull member 201 has a click portion 201 a. The push-pull member 201 and the cell clamping plate 30a are detachably connected with the clamping portion 50 through the clamping portion 201 a. After the battery cell 99 is inserted between the cell clamping plates 30a, the push-pull member 201 is pressed against the cell clamping plates 30 a. In the arrangement direction X, the push-pull member 201 urges the cell clamping plate 30a to move from the releasing position to the clamping position. The touching member 202 touches the force receiving portion 421 of the locking member 42 to lock the locking portion 422 with the locking portion 20 b. The push-pull member 201 is separated from the cell clamping plate 30 a. After the formation or infiltration process of the battery cell 99 is completed, the push-pull member 201 is connected to the battery cell clamping plate 30a in a clamping manner. The touching member 202 touches the force receiving portion 421 of the locking member 42 to unlock the locking portion 422 and the locking portion 20 b. The push-pull member 201 pulls the cell clamping plate 30a to move from the clamping position to the releasing position in the arrangement direction X. In one example, the force receiving portion 421 is a frame structure having a central relief hole 421 c. Along the extending direction of the sliding rail 41, one of the two frames opposite to the force-receiving portion 421 forms a first force-receiving member 421a, and the other forms a second force-receiving member 421 b. The clamping portion 50 is disposed corresponding to the central avoiding hole 421 c. The push-pull member 201 can drive the trigger member 202 and the locking portion 201a to extend into or withdraw from the central avoiding hole 421 c.
Referring to fig. 7 to 10, the push-pull mechanism 200 further includes a rotation driving member 203, and an output end of the rotation driving member 203 is connected to the push-pull member 201. The rotating driving member 203 drives the push-pull member 201 to rotate to drive the triggering member 202 to trigger the force-receiving portion 421. The rotation driving part 203 can drive the push-pull part 201 to do 360-degree rotation. In one example, when the push-pull member 201 presses against the cell clamping plate 30a and pushes the cell clamping plate 30a, the force receiving portion 421 of the locking member 42 is not yet activated by the activating member 202. Referring to fig. 11, when the push-pull member 201 pushes the cell clamping plate 30a to the clamping position, the rotation driving member 203 drives the push-pull member 201 to rotate, and the triggering member 202 synchronously rotates and triggers the first force-receiving member 421a of the force-receiving portion 421, so that the locking member 42 moves in a direction approaching the tray 20 as a whole until the locking portion 422 is locked with the locking portion 20 b. When the cell clamping plate 30a needs to be pulled by the push-pull member 201, the rotation driving member 203 drives the push-pull member 201 to rotate, the triggering member 202 synchronously rotates and triggers the second force-receiving member 421b of the force-receiving portion 421, so that the locking member 42 integrally moves in a direction away from the tray 20 until the locking portion 422 and the locking portion 20b are unlocked. At this time, the push-pull member 201 is connected to the cell clamping plate 30a, so that the push-pull member 201 can apply a pulling force in the arrangement direction X to the cell clamping plate 30a to pull the cell clamping plate 30 a. In one example, the latching portion 201a of the push-pull member 201 is latched to the latch plate 50a, so that the push-pull member 201 can apply a pulling force to the cell holder plate 30a through the latch plate 50 a.
In another example, referring to fig. 12, the locking part 422 includes a latch shaft 422a connected with the force receiving part 421 and an elastic member 422 b. When the cell clamping plate 30a is not in the clamping position, the elastic member 422b is in a compressed state. When the push-pull member 201 presses against the cell clamping plate 30a and pushes the cell clamping plate 30a, the triggering member 202 may not trigger the first force-receiving member 421a of the force-receiving portion 421 of the locking member 42. When the push-pull member 201 pushes the cell clamping plate 30a to move to the clamping position, the latch shaft 422a is inserted into the locking part 20b under the elastic restoring force of the elastic member 422b, so that on one hand, the locking part 422 and the locking part 20b are pre-locked; on the other hand, the cell clamping plate 30a can no longer move further, so that the possibility that the cell clamping plate 30a gets over the locking portion 20b and the locking portion 422 cannot be locked with the locking portion 20b is reduced. Then, referring to fig. 14, the rotation driving member 203 drives the push-pull member 201 to rotate, and the triggering member 202 synchronously rotates and triggers the first force-receiving member 421a of the force-receiving portion 421, so that the locking member 42 integrally moves until the locking portion 422 and the locking portion 20b are switched from the pre-locking state to the fully locking state. Thus, the locking state of the locking part 422 and the locking part 20b is ensured reliably and stably by the cooperation of the elastic part 422b and the touch part 202. Referring to fig. 12, when the push-pull member 201 is required to pull the cell clamping plate 30a, the rotation driving member 203 drives the push-pull member 201 to rotate, and the triggering member 202 synchronously rotates and triggers the second force-receiving member 421b of the force-receiving portion 421, so that the locking member 42 moves in a direction away from the tray 20 as a whole until the locking portion 422 is unlocked from the locking portion 20 b. At this time, the latch shaft 422a is separated from the locking part 20b and compresses the elastic member 422 b. The push-pull member 201 is connected to the cell clamping plate 30a, so that the push-pull member 201 can apply a pulling force in the arrangement direction X to the cell clamping plate 30a to pull the cell clamping plate 30 a. In one example, the latching portion 201a of the push-pull member 201 is latched to the latch plate 50a, so that the push-pull member 201 can apply a pulling force to the cell holder plate 30a through the latch plate 50 a.
Alternatively, as shown in fig. 8, the push-pull member 201 includes a push-pull rod. The touch member 202 is an eccentric circular structure or a convex column connected to the push-pull rod. Optionally, the eccentric circular structure is an eccentric cam. When the push-pull member 201 pushes the cell clamping plate 30a to move toward the clamping position, the push-pull member 201 may be pressed against the cell clamping plate 30a by the touching member 202. Specifically, the push-pull rod may be pressed against the cell clamping plate 30a by an eccentric circle structure or a convex pillar toward the surface of the cell clamping plate 30a, so as to apply a pushing force to the cell clamping plate 30 a.
The cell clamp 10 further includes a clamping portion 50 disposed on the outermost cell clamping plate 30 a. The clamping portion 50 is disposed between the first force-receiving member 421a and the second force-receiving member 421 b. The push-pull member 201 has a click portion 201 a. The push-pull member 201 and the cell clamping plate 30a are detachably connected with the clamping portion 50 through the clamping portion 201 a. Referring to fig. 12 and 13, when the push-pull member 201 is required to pull the cell clamping plate 30a, the rotation driving member 203 drives the push-pull member 201 to rotate, and the triggering member 202 synchronously rotates and triggers the second force-receiving member 421b of the force-receiving portion 421, so that the locking member 42 integrally moves in a direction away from the tray 20 until the locking portion 422 and the locking portion 20b are unlocked. At this time, the latching portion 201a of the push-pull member 201 and the latching portion 50 are latched and connected, so that the push-pull member 201 can apply a pulling force in the arrangement direction X to the cell clamping plate 30a through the latching portion 50 to pull the cell clamping plate 30 a. Referring to fig. 15, when the push-pull member 201 pushes the cell clamping plate 30a to move to the clamping position, or after the locking portion 422 and the locking portion 20b are locked, the push-pull member 201 needs to be separated from the cell clamping plate 30a, the buckling portion 201a and the buckling portion 50 are in an unclamped state. In one example, the push-pull member 201 presses against the cell clamping plate 30a through the trigger member 202 to apply a pushing force to the cell clamping plate 30a to push the cell clamping plate 30a to move toward the clamping position. At this time, the locking portion 201a and the locking portion 50 are not locked. In one example, the clamping portion 50 includes a hole 50b opened on the cell clamping plate 30a and a clamping plate 50a partially covering the hole 50 b. The locking portion 201a is a locking groove. The rotating driving part 203 drives the pushing and pulling part 201 to rotate so as to drive the clamping groove to be clamped with or separated from the clamping plate 50 a.
Referring to fig. 6 and 9, the push-pull mechanism 200 further includes a movement driving part 204 connected to the rotation driving part 203. The movement driving part 204 includes a power source 204a and a guide rail 204 b. The guide rail 204b extends in the arrangement direction X. The rotation driving member 203 is movably connected to the guide rail 204 b. The power source 204a drives the rotary driving member 203 to move along the guide rail 204b to drive the push-pull member 201 to move synchronously, so as to push and pull the cell clamping plate 30a through the push-pull member 201. The automation degree of the battery cell clamping device 100 is improved by moving the driving component 204 to drive the push-pull component 201 to move. In one example, the power source 204a may be a servo motor or a stepper motor. The guide 204b may be a lead screw. The rotation driving member 203 is screwed to the guide rail 204 b. The power source 204a can drive the guide rail 204b to rotate, so as to drive the rotary driving component 203 to move along the guide rail 204 b. In another example, power source 204a may be a hydraulic cylinder or an electric cylinder with a telescopic shaft. The guide rail 204b is a linear rail extending in a straight line. The rotation driving part 203 is slidably connected to the guide rail 204 b. The telescopic shaft of the power source 204a is connected to the rotary drive member 203. The telescopic shaft of the power source 204a moves telescopically to move the rotary driving member 203 along the guide rail 204 b.
In one example, referring to fig. 7 and 9, the rotation driving part 203 includes a base 203a, a telescopic cylinder 203b, and a rack 203c connected with the telescopic cylinder 203 b. The push-pull member 201 is rotatably coupled to the base 203 a. The telescopic cylinder 203b is connected to the base 203 a. The rack 203c is movably coupled to the base 203 a. The push-pull member 201 has a driven gear portion 201b that meshes with the rack 203 c. One end of the push-pull member 201 is connected to the base 203a through a bearing. The telescopic cylinder 203b has a telescopic shaft. The telescopic shaft is connected with the rack 203 c. When the telescopic shaft is moved in a telescopic manner in a direction perpendicular to the arrangement direction X, the rack 203c can be driven to move relative to the base 203a, and the rack 203c can drive the push-pull member 201 to rotate via the driven gear portion 201 b. Alternatively, the telescopic cylinder 203b may be a hydraulic cylinder or an electric cylinder. In one example, the number of the push-pull members 201 is one-to-one corresponding to the number of the locksets 40 and is two. The two push-pull members 201 are driven to rotate by one rack 203c at the same time, so that the triggering member 202 synchronously triggers the two force-receiving parts 421, and the two locking parts 422 are synchronously locked or unlocked with the two locking parts 20 b.
The push-pull mechanism 200 also includes a frame that provides a mounting base. The movement driving part 204 is connected to the frame. The rotation driving part 203 is connected to the frame by a movement driving part 204.
