Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0052] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0053] Please also read Figure 1 , Figure 2 and Figure 3 The present application discloses a clamping device 1, including a base 11, a first clamping jaw assembly 12, a second clamping jaw assembly 13, a third clamping jaw 14, a first elastic member 151, a second elastic member 152 and a matching member 16. The first clamping jaw assembly 12 is movably disposed on the base 11. The second clamping jaw assembly 13 is movably disposed on the base 11. The second clamping jaw assembly 13 and the first clamping jaw assembly 12 are movably disposed on the base 11. Figure 2 The third clamping jaw 14 is disposed on the base 11, and the third clamping jaw 14 and the first clamping jaw assembly 12 are arranged in the second direction, and the third clamping jaw 14 and the second clamping jaw assembly 13 are arranged in the second direction (as shown in FIG. Figure 1 The first and second jaw assemblies 151 and 152 are arranged on a vertical axis (shown as X in the figure), and the second direction is perpendicular to the first direction. The first elastic member 151 is used to apply a first elastic force to the first jaw assembly 12 and the second jaw assembly 13 to move closer to each other. The second elastic member 152 is used to apply a second elastic force to the first jaw assembly 12 and the second jaw assembly 13 to move closer to the third jaw 14. The matching member 16 can move from the first position to the second position along the second direction to overcome the second elastic force and make the first jaw assembly 12 and the second jaw assembly 13 move away from the third jaw 14 along the second direction. The matching member 16 can move from the second position to the third position along the second direction to overcome the first elastic force and make the first jaw assembly 12 and the second jaw assembly 13 move away from each other along the first direction. The second position is located between the first position and the third position.

[0054] The base 11 is fixed in the first direction and the second direction.

[0055] The first elastic member 151 is used to apply a first elastic force to the first jaw assembly 12 and the second jaw assembly 13 to move them closer to each other. The first elastic member 151 can apply the first elastic force directly to the first jaw assembly 12 and the second jaw assembly 13, or the first elastic member 151 can apply the first elastic force indirectly to the first jaw assembly 12 and the second jaw assembly 13, which is not limited here.

[0056] Similarly, the second elastic member 152 is used to apply a second elastic force close to the third jaw 14 to the first jaw assembly 12 and the second jaw assembly 13. The second elastic member 152 can directly apply the second elastic force to the first jaw assembly 12 and the second jaw assembly 13, or the second elastic member 152 can indirectly apply the second elastic force to the first jaw assembly 12 and the second jaw assembly 13, which is not limited here.

[0057] In this embodiment, when the mating piece 16 is in the first position, the distance between the first jaw assembly 12 and the second jaw assembly 13 in the first direction is minimized, so that the first jaw assembly 12 and the second jaw assembly 13 can clamp the battery cell in the first direction, and at the same time, the distance between the first jaw assembly 12, the second jaw assembly 13 and the third jaw 14 in the second direction is minimized, so that the first jaw assembly 12, the second jaw assembly 13 and the third jaw 14 can clamp the battery cell in the second direction.

[0058] In the process of the fitting 16 moving from the first position to the second position along the second direction, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 overcome the second elastic force and move away from the third clamping jaw 14 along the second direction, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 and the third clamping jaw 14 in the second direction gradually increases, thereby unlocking the battery cell in the second direction. It should be noted that in the process of the first clamping jaw assembly 12 and the second clamping jaw assembly 13 moving away from the third clamping jaw 14, the second elastic force gradually increases. In addition, in the process of the fitting 16 moving from the first position to the second position, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 cannot overcome the first elastic force, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction remains unchanged.

[0059] When the mating piece 16 is in the second position, the second elastic force increases to a limit value, so that the first jaw assembly 12 and the second jaw assembly 13 cannot continue to move away from the third jaw 14 along the second direction, that is, the distance between the first jaw assembly 12 and the third jaw 14 in the second direction reaches a maximum value, and the distance between the second jaw assembly 13 and the third jaw 14 in the second direction also reaches a maximum value.

[0060] During the process of the mating member 16 moving from the second position to the third position along the second direction, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 remain stationary in the second direction, and the first clamping jaw assembly 12 and the second clamping jaw assembly 13 can overcome the first elastic force and move away from each other in the first direction, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction gradually increases, thereby unlocking the battery cell in the first direction. It should be noted that during the process of the first clamping jaw assembly 12 and the second clamping jaw assembly 13 gradually moving away from each other, the first elastic force gradually increases, and at the same time, the distance between the first clamping jaw assembly 12 and the third clamping jaw 14 in the second direction remains unchanged, and the distance between the second clamping jaw assembly 13 and the third clamping jaw 14 in the second direction remains unchanged.

[0061] When the matching member 16 is at the third position, the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction reaches a maximum value.

[0062] It should be noted that, in the present embodiment, during the process when the first jaw assembly 12 and the second jaw assembly 13 are close to the third jaw 14, and during the process when the first jaw assembly 12 and the second jaw assembly 13 are away from the third jaw 14, the battery cell can be positioned by the third jaw 14 or by an external mechanism, which is not limited here.

[0063] In the clamping device 1 of this embodiment, when the matching member 16 is located at the first position, the second elastic member 152 applies a second elastic force toward the third clamping jaw 14 to the first clamping jaw assembly 12 and the second clamping jaw assembly 13 to clamp the battery cell in the second direction, thereby reducing the complexity of the structure of clamping the battery cell. At the same time, the matching member 16 moves from the first position to the second position, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are away from the third clamping jaw 14, so as to unlock the battery cell in the second direction, thereby reducing the complexity of the structure of unlocking the battery cell. The matching member 16 continues to move from the second position to the third position, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are away from each other, so as to increase the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction, so as to achieve the effect of avoiding. Among them, achieving the effect of avoiding means that there is a subsequent mechanism (not shown in the figure) in the subsequent process, and the subsequent mechanism approaches the third clamping jaw along the second direction to remove the battery cell from the clamping device 1. Therefore, after the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are away from each other, the purpose of avoiding the subsequent mechanism can be achieved.

[0064] In summary, this embodiment only uses the driving member 18 to drive the matching member 16 to switch between the first position and the third position along the second direction, so as to achieve clamping or unlocking of the battery cell. Compared with the method of clamping or unlocking the battery cell adopted in the prior art (for example, the process of realizing the unlocking action is that the translation cylinder first drives the latch mechanism to translate, and then the lifting slide cylinder drives the latch mechanism to rise to insert the latch into the pin hole to be unlocked, and then the translation cylinder retracts and the clamping claw cylinder opens, thereby realizing the unlocking action of the battery cell; the clamping action is opposite to the unlocking action), it saves the number of cylinders and simplifies the process of clamping or unlocking the battery cell, reduces the structural complexity of the clamping device 1, and also reduces the cost of the clamping device 1 during the manufacturing or maintenance process.

[0065] See also Figure 4 In some embodiments, the mating piece 16 has a guide portion 161, and the width of the guide portion 161 along the first direction gradually increases from the second position in the direction toward the first position to form a first guide slope 162 and a second guide slope 163 opposite to each other, the first clamping jaw assembly 12 abuts against the first guide slope 162, and the second clamping jaw assembly 13 abuts against the second guide slope 163.

[0066] In this embodiment, the end of the guide portion 161 with the smallest width along the first direction is the first end, and the end with the largest width along the first direction is the second end, that is, the width of the guide portion 161 in the first direction gradually increases from the first end to the second end. In addition, the first clamping jaw assembly 12 can move along the first guide inclined surface 162, and the second clamping jaw assembly 13 can move along the second guide inclined surface 163.

[0067] Specifically, when the fitting 16 is in the first position, the first clamping assembly 12 and the second clamping assembly 13 are located at the first end of the guide portion 161, so that the distance between the first clamping assembly 12 and the second clamping assembly 13 in the first direction is minimized to clamp the battery cell in the first direction.

[0068] During the movement of the fitting 16 from the first position to the second position along the second direction, the force component in the second direction of the force applied by the first guide slope 162 to the first clamping jaw assembly 12 and the force component in the second direction of the force applied by the second guide slope 163 to the second clamping jaw assembly 13 can overcome the second elastic force, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 and the third clamping jaw 14 in the second direction gradually increases. At the same time, the force component in the first direction of the force applied by the first guide slope 162 to the first clamping jaw assembly 12 and the force component in the first direction of the force applied by the second guide slope 163 to the second clamping jaw assembly 13 cannot overcome the first elastic force, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are always located at the first end of the guide portion 161. In other words, the relative position between the first clamping jaw assembly 12 and the first guide slope 162 remains unchanged, and the relative position between the second clamping jaw assembly 13 and the second guide slope 163 remains unchanged, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction remains unchanged.

[0069] When the mating piece 16 moves to the second position, the second elastic force increases to a limit value, and the component of the force applied by the first guide slope 162 to the first clamping jaw assembly 12 in the second direction and the component of the force applied by the second guide slope 163 to the second clamping jaw assembly 13 in the second direction cannot overcome the second elastic force, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 cannot continue to move along the second direction.

[0070] During the movement of the fitting 16 from the second position to the third position along the second direction, the second elastic force prevents the first clamping jaw assembly 12 and the second clamping jaw assembly 13 from continuing to move away from the third clamping jaw 14 along the second direction, and the force component in the first direction of the force applied by the first guide slope 162 to the first clamping jaw assembly 12 and the force component in the first direction of the force applied by the second guide slope 163 to the second clamping jaw assembly 13 are greater than the first elastic force, so that the first clamping jaw assembly 12 and the first clamping jaw assembly 12 can overcome the first elastic force, and the first clamping jaw assembly 12 moves from the first end to the second end relative to the first guide slope 162, and the second clamping jaw assembly 13 moves from the first end to the second end relative to the second guide slope 163. Since the width of the guide portion 161 in the first direction gradually increases from the first end to the second end, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 move away from each other in the first direction, thereby unlocking the battery cell in the first direction.

[0071] It is understandable that, when the fitting 16 moves from the second position to the third position, the movement between the first clamping jaw assembly 12 and the first guide slope 162 and between the second clamping jaw assembly 13 and the second guide slope 163 can be sliding or rolling, which is not limited here.

[0072] In the present embodiment, during the movement of the mating member 16 from the second position to the third position, the first clamping jaw assembly 12 is driven to move in the first direction by the first guide slope 162, and the second clamping jaw assembly 13 is driven to move in the first direction by the second guide slope 163. Compared with the prior art (for example, the latch mechanism is first driven to translate by the translation cylinder, and then the latch mechanism is driven to rise by the lifting slide cylinder to insert the latch into the pin hole to be unlocked, and then the translation cylinder retracts and the clamping jaw cylinder opens, thereby realizing the unlocking action of the battery cell), the unlocking process is simplified and the complexity of the structure is reduced.

[0073] In some other embodiments, a first slide rail and a second slide rail can be set on the mating piece 16, and the distance between the first slide rail and the second slide rail in the first direction gradually increases from the second position toward the first position. The first clamping jaw assembly 12 is slidably set on the first slide rail, and the second clamping jaw assembly 13 is slidably set on the second slide rail.

[0074] Please also read Figure 2 and Figure 4 In some more specific embodiments, the first clamping jaw assembly 12 includes a first clamping jaw 121, a first sliding member 122 and a first rolling member 123. The first clamping jaw 121 is connected to the first sliding member 122, the first rolling member 123 is rotatably disposed on the first sliding member 122, and the first rolling member 123 abuts against the first guide inclined surface 162. The second clamping jaw assembly 13 includes a second clamping jaw 131, a second sliding member 132 and a second rolling member 133. The second clamping jaw 131 is connected to the second sliding member 132, the second rolling member 133 is rotatably disposed on the second sliding member 132, and the second rolling member 133 abuts against the second guide inclined surface 163.

[0075] It should be noted that, in this embodiment, when the matching member 16 moves from the second position to the third position along the second direction, the first sliding member 122 and the second sliding member 132 can move along the first direction.

[0076] Specifically, when the fitting 16 is in the first position, the distance between the first clamping jaw 121 and the second clamping jaw 131 in the first direction is the smallest, and the first clamping jaw 121 and the second clamping jaw 131 clamp the battery cell with the third clamping jaw 14 in the second direction.

[0077] During the movement of the mating member 16 from the first position to the second position along the second direction, the force component in the second direction of the force applied by the first guide slope 162 to the first rolling member 123 and the force component in the second direction of the force applied by the second guide slope 163 to the second rolling member 133 can overcome the second elastic force, so that the distance between the first clamping jaw 121 and the second clamping jaw 131 and the third clamping jaw 14 in the second direction gradually increases. At the same time, the force component in the first direction of the force applied by the first guide slope 162 to the first rolling member 123 and the force component in the first direction of the force applied by the second guide slope 163 to the second rolling member 133 cannot overcome the first elastic force, so that the relative position between the first rolling member 123 and the first guide slope 162 remains unchanged, and the relative position between the second rolling member 133 and the second guide slope 163 remains unchanged, so that the distance between the first clamping jaw 121 and the second clamping jaw 131 in the first direction remains unchanged.

[0078] When the mating member 16 moves to the second position, the second elastic force increases to a limit value, and the component of the force applied by the first guide slope 162 to the first rolling member 123 in the second direction and the component of the force applied by the second guide slope 163 to the second rolling member 133 in the second direction cannot overcome the second elastic force, so that the first clamp 121 and the second clamp 131 cannot continue to move away from the third clamp 14 along the second direction.

[0079] When the mating member 16 moves from the second position to the third position along the second direction, the component of the force applied by the first guide slope 162 to the first rolling member 123 in the first direction and the component of the force applied by the second guide slope 163 to the second rolling member 133 in the first direction are greater than the first elastic force, so that the first rolling member 123 and the second rolling member 133 can overcome the first elastic force, and the first rolling member 123 rolls along the first guide slope 162, and the second rolling member 133 rolls along the second guide slope 163, and the first rolling member 123 and the second rolling member 133 move away from each other in the first direction, so that the first clamp 121 and the second clamp 131 move away from each other in the first direction to unlock the battery cell in the first direction.

[0080] In this embodiment, the first rolling member 123 and the first guiding bevel 162 are rollingly matched, so that rolling friction is formed between the first rolling member 123 and the first guiding bevel 162. At the same time, the second clamping jaw assembly 13 is rollingly matched with the second guiding bevel 163 through the second rolling member 133, so that rolling friction is formed between the second rolling member 133 and the second guiding bevel 163. The friction loss between the first clamping jaw assembly 12 and the first guiding bevel 162 and between the second clamping jaw assembly 13 and the second guiding bevel 163 can be reduced, thereby extending the service life of the first clamping jaw assembly 12, the second clamping jaw assembly 13 and the matching member 16.

[0081] In some other more specific embodiments, the first sliding member 122 may abut against the first guiding inclined surface 162 and slide along the first guiding inclined surface 162 , and the second sliding member 132 may abut against the second guiding inclined surface 163 and slide along the second guiding inclined surface 163 .

[0082] See also Figure 2 In some embodiments, the first elastic member 151 is connected to the first sliding member 122 and the second sliding member 132 , and applies a first elastic force to the first sliding member 122 and the second sliding member 132 .

[0083] In this embodiment, since the first sliding member 122 and the second sliding member 132 can move along the first direction, the two ends of the first elastic member 151 are connected to the first sliding member 122 and the second sliding member 132, and apply a first elastic force to the first sliding member 122 and the second sliding member 132 to move closer to each other, which can reduce the torque generated by the first elastic force acting on the first clamping jaw assembly 12 and the second clamping jaw assembly 13, thereby preventing the first sliding member 122 and the second sliding member 132 from getting stuck or even stagnant when sliding along the first direction.

[0084] In some other embodiments, the first elastic member 151 may also be connected between the first clamping jaw 121 and the second clamping jaw 131 .

[0085] In some more specific embodiments, the first elastic member 151 is a spring in a stretched state.

[0086] In this embodiment, the first elastic member 151 is a spring in a stretched state, and the spring extends along the first direction to apply a first elastic force along the first direction to the first sliding member 122 and the second sliding member 132 .

[0087] In some other more specific implementations, the first elastic member 151 may also be a rubber band or the like.

[0088] Please refer again Figure 1 and Figure 2 In some embodiments, the clamping device 1 further includes a first guide rail 171, a bearing member 172, and a second guide rail 173. The first guide rail 171 is disposed on the base 11 along the second direction. The bearing member 172 is slidably disposed on the first guide rail 171, and the second elastic member 152 is connected to the bearing member 172 and the base 11. The second guide rail 173 is disposed on the bearing member 172 along the first direction, and the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are slidably disposed on the second guide rail 173. The second elastic member 152 applies a second elastic force to the first clamping jaw assembly 12 and the second clamping jaw assembly 13 through the bearing member 172.

[0089] In this embodiment, the carrier 172 is provided with a second guide rail 173 extending along the first direction, and the first clamping jaw assembly 12 and the second clamping jaw assembly 13 are provided on the second guide rail 173, which can limit the relative movement between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 and the carrier 172 along the first direction, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 and the carrier 172 move synchronously in the first direction. The second elastic member 152 is connected to the carrier 172 and applies a second elastic force to the carrier 172, so that the second elastic force is indirectly applied to the first clamping jaw assembly 12 and the second clamping jaw assembly 13.

[0090] Specifically, in the process of the matching member 16 moving from the first position to the second position along the second direction, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 move away from the third clamping jaw 14 along the second direction, and drive the carrier 172 to overcome the second elastic force and move along the first guide rail 171, thereby unlocking the battery cell in the second direction. It should be noted that in the process of the first clamping jaw assembly 12 and the second clamping jaw assembly 13 moving away from the third clamping jaw 14, the second elastic force applied by the second elastic member 152 to the carrier 172 gradually increases. In addition, in the process of the matching member 16 moving from the first position to the second position, the first clamping jaw assembly 12 and the second clamping jaw assembly 13 cannot overcome the first elastic force, so that the first clamping jaw assembly 12 and the second clamping jaw assembly 13 cannot move along the second guide rail 173, so that the distance between the first clamping jaw assembly 12 and the second clamping jaw assembly 13 in the first direction remains unchanged.

[0091] When the fitting member 16 is in the second position, the second elastic force increases to a limit value, so that the bearing member 172 cannot continue to move along the second direction.

[0092] During the movement of the mating member 16 from the second position to the third position along the second direction, since the carrier 172 remains stationary in the second direction, the positions of the first clamping assembly 12 and the second clamping assembly 13 in the second direction remain unchanged, that is, the distance between the first clamping assembly 12 and the second clamping assembly 13 and the third clamping assembly 14 in the second direction remains unchanged. The first clamping assembly 12 and the second clamping assembly 13 can overcome the first elastic force and move away from each other along the second guide rail 173, so that the distance between the first clamping assembly 12 and the second clamping assembly 13 in the first direction gradually increases, thereby unlocking the battery cell in the first direction. It should be noted that during the process of the first clamping assembly 12 and the second clamping assembly 13 gradually moving away from each other, the first elastic force can gradually increase.

[0093] In some other embodiments, the second guide rail 173 may be disposed on the first guide rail 171 , and the second elastic member 152 is connected to the second guide rail 173 and the base 11 .

[0094] In some embodiments, the second elastic member 152 is a spring in a compressed state.

[0095] In this embodiment, the second elastic member 152 is a spring in a compressed state, and the spring extends along the second direction to apply a second elastic force along the second direction to the supporting member 172 .

[0096] In some other more specific implementations, the second elastic member 152 may also be a rubber band or the like.

[0097] See also Figure 1 In some embodiments, the clamping device 1 further includes a driving member 18, and the driving member 18 is connected to the matching member 16 to drive the matching member 16 to move between the first position and the second position and between the second position and the third position.

[0098] The driving member 18 drives the mating member 16 to move between the first position and the second position and between the second position and the third position, and can accurately control the driving force applied by the driving member 18 to the mating member 16. At the same time, the driving member 18 in this embodiment only needs to drive the mating member 16, thereby reducing the manufacturing and maintenance costs of the clamping device 1.

[0099] In some other embodiments, the driving member 18 may only drive the matching member 16 to move from the first position to the third position.

[0100] In some embodiments, the driving member 18 is a pen-shaped cylinder.

[0101] Since the matching piece 16 moves only in the second direction, the pen-shaped cylinder is used in this embodiment to drive the matching piece 16, so that the linear driving mode of the pen-shaped cylinder matches the linear movement of the matching piece 16. At the same time, since the pen-shaped cylinder is light in weight, the weight of the clamping device 1 can be reduced. In addition, since the pen-shaped cylinder has a simple structure and is usually made of materials with good wear resistance, the cost of the pen-shaped cylinder is lower than that of other driving parts, so the cost of the clamping device 1 can be reduced by using a pen-shaped cylinder to drive the matching piece 16.

[0102] In some other embodiments, the driving member 18 may also be a hydraulic cylinder or the like.

[0103] Please also read Figure 4 and Figure 5 In some embodiments, the clamping device 1 further includes a connecting member 191, a first limiting member 192, and a second limiting member 193. The connecting member 191 connects the driving member 18 and the matching member 16, the first limiting member 192 and the second limiting member 193 are spaced apart on the base 11 along the second direction, and at least a portion of the connecting member 191 is located between the first limiting member 192 and the second limiting member 193 to limit the matching member 16 from moving between the first position and the third position.

[0104] In this embodiment, when the driving member 18 drives the connecting member 191 to abut against the first limiting member 192, the matching member 16 is in the first position, and when the driving member 18 drives the connecting member 191 to abut against the second limiting member 193, the matching member 16 is in the third position. The first limiting member 192 and the second limiting member 193 limit the movement range of the connecting member 191 in the second direction, thereby limiting the movement of the matching member 16 between the first position and the third position.

[0105] In some other embodiments, the first limiting member 192 and the second limiting member 193 may also be used to abut against the matching member 16 to limit the movement of the matching member 16 between the first position and the second position.
