[0025] Referring to Figures 1 to 3A battery capacity distribution clamping device, comprising: a cabinet body 100, the cabinet body 100 is spaced apart in the height direction and is provided with a plurality of placement plates 110, and the lower side of each placement plate 110 is movably provided with an adjusting plate 120, the adjusting plate 120 is provided with a locking assembly, the locking assembly is used for fixing the position of the adjusting plate 120 after movement, each placement plate 110 is fixedly provided with a plurality of first clamping plates 130 along the length direction thereof, each first clamping plate 130 is oppositely provided with a second clamping plate 140, the first clamping plate 130 and the second clamping plate 140 are used for jointly clamping a battery, and each second clamping plate 140 is provided with an elastic assembly between the adjusting plate 120, the elastic assembly is used for driving the second clamping plate 140 to move close to the first clamping plate 130, each second clamping plate 140 is rotatably provided with a locking piece 160, the adjusting plate 120 is provided with a limiting groove 121 matched with the locking piece 160, and when the locking piece 160 is rotated to be clamped on the inner wall of the limiting groove 121, the locking piece 160 is used for fixing the second clamping plate 140 to the adjusting plate 120.

[0026] The battery capacity distribution clamping device with the above structure, in use, a plurality of locking pieces 160 are rotated, so that each locking piece 160 is clamped in the corresponding limiting groove 121, so that a plurality of second clamping plates are fixed to the adjusting plate 120, then the adjusting plate 120 is moved, so that the clamping spacing of the first clamping plate 130 and the second clamping plate 140 matches the thickness of the required battery, and finally the position of the adjusting plate 120 after movement is fixed by the locking assembly, thereby facilitating subsequent placement of a plurality of batteries for clamping. When encountering batteries of different thicknesses, the locking piece 160 is re-rotated, so that the corresponding second clamping plate 140 can move under the action of the elastic assembly, which is conducive to adjusting the spacing of the corresponding first clamping plate 130 and the second clamping plate 140 to adapt to the clamping of batteries of different thicknesses, thereby improving the applicability of the device.

[0027] Referring to Figures 1 to 3 Further, the second clamping plate 140 is provided with a side extension plate 141, the locking piece 160 comprises a threaded rod 161 threadedly matched with the side extension plate 141, one end of the threaded rod 161 is provided with a limiting rod 162, the adjusting plate 120 is parallelly provided with at least two vertical rods 122, the limiting groove 121 is defined between the two vertical rods 122, and the limiting rod 162 is rotated between the two vertical rods 122. Specifically, in use, the limiting rod 162 is rotated, so that the two ends of the limiting rod 162 are respectively abutted against the corresponding vertical rods 122, which is conducive to fixing the second clamping plate 140 to the adjusting plate 120. Among them, the threaded rod 161 is threadedly matched with the side extension plate 141, which is conducive to fixing the angle of rotation of the limiting rod 162 by the threaded action.

[0028] Further, the vertical rods 122 are provided with arc-shaped surfaces (not shown in the figure) facing the limiting rod 162, and the centers of the arc-shaped surfaces are located on the rotation axis of the limiting rod 162. Specifically, the two arc-shaped surfaces together form a circular region matching the rotation track of the limiting rod 162, which is conducive to the rotation of the limiting rod 162 between the two vertical rods 122. It can be understood that the end surface of the limiting rod 162 is a convex surface matching the arc-shaped surface, and when the limiting rod 162 is rotated to the horizontal position, the limiting rod 162 can better limit the movement of the second clamping plate 140.

[0029] Referring to Figure 3 Further, the elastic assembly comprises the elastic member 150 and the mounting rod 151, one end of the mounting rod 151 is arranged on the adjusting plate 120, the other end of the mounting rod 151 is provided with the first limiting member 152, the elastic member 150 is sleeved outside the mounting rod 151, the placement plate 110 is provided with the first long hole 111, the second clamping plate 140 is provided with the mounting plate 142 which is in sliding cooperation with the first long hole 111, the mounting plate 142 is provided with a through hole for the mounting rod 151 to pass through, and one end of the elastic member 150 abuts against the mounting plate 142. Specifically, when the limiting rod 162 is rotated to the vertical position, a battery with a thickness greater than the original clamping interval is placed between the first clamping plate 130 and the second clamping plate 140, the battery pushes the second clamping plate 140 to move, and the elastic member 150 generates an elastic force to drive the second clamping plate 140 to abut against the battery, thereby increasing the interval between the first clamping plate 130 and the second clamping plate 140 to adapt to the clamping of the battery with a large thickness. If it is necessary to clamp a battery with a thickness less than the original clamping interval, the position of the first limiting member 152 needs to be adjusted, so that the elastic member 150 can continue to drive the second clamping plate 140 to move closer to the first clamping plate 130, which is conducive to reducing the interval between the first clamping plate 130 and the second clamping plate 140, thereby adapting to the clamping of batteries with different thicknesses and improving the applicability of the device.

[0031] Referring to Figure 3 Further, the first limiting member 152 and the second limiting member 153 are limiting nuts which are in threaded cooperation with the mounting rod 151, which is conducive to adjusting the position of one of the limiting nuts to change the elastic deformation stroke of the elastic member 150, so that the second clamping plate 140 can generate a movement displacement adapting to the clamping of batteries with different thicknesses.

[0032] Referring to Figure 3 Further, the elastic member 150 is a spring, one end of the spring is connected to the horizontal rod 123, the other end of the elastic member 150 is connected with a flat plate 154, the flat plate 154 abuts against the mounting plate 142, so that the contact area with the mounting plate 142 is increased by the flat plate 154, thereby facilitating the movement of the mounting plate 142 to move close to the first clamping plate 130.

[0033] Referring to Figures 1 to 3 Further, the placement plate 110 is provided with a second long hole 112, the adjusting plate 120 is provided with a third long hole 124 which is parallel to the second long hole 112, the locking assembly includes a bolt rod 170, both ends of the bolt rod 170 are respectively provided with the second long hole 112 and the third long hole 124, both ends of the bolt rod 170 are provided with locking nuts 171, the two locking nuts 171 are respectively abutted against the placement plate 110 and the adjusting plate 120, a limiting block is arranged between the placement plate 110 and the adjusting plate 120, and the limiting block is movably sleeved on the outer periphery of the bolt rod 170. Specifically, when it is needed to move the adjusting plate 120, one of the locking nuts 171 is loosened, then the adjusting plate 120 is moved according to the thickness of the battery to be clamped, and finally the corresponding locking nut 171 is tightened again after the adjusting plate 120 is moved to the position, so that the vertical clamping force is generated by the two locking nuts 171 to stabilize the position of the adjusting plate 120. Wherein, the limiting block is arranged, which is beneficial to maintain the distance between the placement plate 110 and the adjusting plate 120, thereby facilitating the use of the elastic assembly. It can be understood that the locking assembly can also use a T-shaped pin shaft, the placement plate 110 is provided with a plurality of first through holes, the adjusting plate 120 is provided with a second through hole, the pin shaft is provided through the second through hole and the corresponding first through hole, which can also limit the position of the adjusting plate 120.
