In this embodiment, referring to fig. 2 and 3 in combination, the pick-up assembly 11 includes a bus bar 100, a first connector 300 and a second connector 400 of the FPC member 200. The busbar 100 is electrically connected with the cell; the FPC member 200 is electrically connected with the connector 500; and connector 500 is used to access the control module. The first connector 300 is arranged on the busbar 100, and the second connector 400 is arranged on the FPC member 200; and can realize the electrical connection of busbar 100 and FPC spare 200 through the cooperation of first connecting piece 300 and second connecting piece 400, based on this, busbar 100 can collect the parameter such as temperature, the voltage of electric core and transmit to FPC spare 200, and the water conservancy diversion via FPC spare 200 for the parameter that busbar 100 gathered is carried to control module, and control module just can effectively control holistic energy storage device 10, ensures that energy storage device 10 effectively exports the electric energy steadily.

In this embodiment, the first connector 300 includes a bearing body 310, a limiting portion 320, and an elastic portion 330; the bearing body 310 is arranged on the bus bar 100; the elastic part 330 is arranged on the bearing main body 310; the limiting portion 320 is disposed on the carrier body 310. The second connector 400 includes a connector body 420 and a mating body 410; the connection body 420 is disposed on the FPC member 200, and the mating body 410 is connected to the connection body 420. At least a portion of the mating body 410 is clamped between the resilient portion 330 and the carrier body 310; the engaging body 410 is detachably engaged with the stopper 320.

In the above, in the pickup assembly 11, the connection between the bus bar 100 and the FPC member 200 may be achieved by the assembly of the first connector 300 and the second connector 400; at least a portion of the engaging body 410 is clamped between the elastic portion 330 and the carrier body 310, and at the same time, the engaging body 410 is detachably connected to the first connector 300 by the detachable engagement of the engaging body 410 with the limiting portion 320. After the FPC assembly 200 is scrapped, the connection relationship between the first connector 300 and the second connector 400 can be directly released, so that the FPC assembly 200 can be disassembled, and the replacement of the FPC assembly 200 can be easily completed. Based on this, the technical problem that the replacement is inconvenient after the FPC member 200 is scrapped in the prior art can be solved.

Optionally, referring to fig. 4 in combination, in order to simplify the assembly manner of the first connector 300 and the second connector 400, and further reduce the assembly difficulty of the first connector 300 and the second connector 400, the elastic portion 330 is disposed at one end of the carrying body 310, and the limiting portion 320 is disposed at a distance from the elastic portion 330; the engaging body 410 passes between the elastic portion 330 and the carrier body 310 to engage with the stopper portion 320. In other words, the second connector 400 may be detachably connected to the first connector 300 by being inserted and pulled in a predetermined direction.

For example, the direction from one end to the other end of the carrier body 310 is a predetermined direction, the elastic portion 330 is disposed at one end of the carrier body 310, and the limiting portion 320 and the elastic portion 330 are disposed at intervals along the predetermined direction, for example, the limiting portion 320 is disposed at a middle position of the carrier body 310. During the assembly of the first and second connectors 300 and 400, the fitting body 410 penetrates between the elastic portion 330 and the carrier body 310 in a preset direction, thereby causing the elastic portion 330 and the carrier body 310 to jointly clamp the fitting body 410; after the part of the engaging body 410 passes through between the elastic portion 330 and the carrying body 310, it can move to the position where the limiting portion 320 is located to engage with the limiting portion 320, thereby completing the engagement between the first connector 300 and the second connector 400. In the process of disassembling the first connector 300 and the second connector 400, the second connector 400 may be directly pulled out, so that the fit between the first connector 300 and the second connector 400 may be released, thereby completing the disassembly of the FPC member 200.

It should be understood that in other embodiments of the present application, the positional relationship between the stopper portion 320 and the elastic portion 330 may also be different. For example, the stopper 320 is disposed at an end of the carrier body 310, and the elastic portion 330 is disposed at a middle of the carrier body 310. At this time, the second connector 400 may be assembled to the first connector 300 in a predetermined direction, so that the engaging body 410 simultaneously completes the engagement with the elastic portion 330 and the engagement with the limiting portion 320.

It should be noted that, in the present embodiment, the first connector 300 and the second connector 400 are assembled and disassembled by inserting and pulling the first connector 300 and the second connector 400 along a linear direction; as shown in fig. 4, the second connector 400 may be inserted in the direction indicated by the arrow B in fig. 4 to be assembled with the first connector 300; the second connector 400 may also be pulled out in the direction indicated by the arrow C in fig. 4 to disengage from the first connector 300. In other embodiments, the first connector 300 and the second connector 400 may be assembled and disassembled in other manners. For example, first, the first stage positioning of the mating body 410 and the first connector 300 is achieved by the mating of the mating body 410 and the limiting portion 320, and then the mating body 410 is rotated about the limiting portion 320, so that the mating body 410 is clamped between the elastic portion 330 and the bearing body 310, thereby achieving the mating of the first connector 300 and the second connector 400; in the disassembly process, only the engaging body 410 is required to be rotated to disengage the elastic portion 330 and the bearing body 310, and then the engaging of the limiting portion 320 and the engaging body 410 is released, so that the disassembly of the first connector 300 and the second connector 400 can be completed.

In the present embodiment, referring to fig. 3 and fig. 5 in combination, the limiting portion 320 is protruding on the carrying body 310; the matching body 410 is provided with a limiting hole 411 adapted to the limiting portion 320, and the limiting portion 320 is detachably matched with the limiting hole 411. In other words, the limiting portion 320 extends into the limiting hole 411, so that the limiting portion 320 can provide a limiting effect to the mating body 410 by abutting against the inner peripheral wall of the limiting hole 411.

Optionally, in the embodiment of the present application, in order to facilitate the matching of the matching body 410 with the limiting portion 320, the limiting portion 320 is approximately hemispherical, so that the outer periphery of the limiting portion 320 forms a curved surface with a circular arc shape, and when the matching body 410 moves along the bearing body 310 to the limiting portion 320, the curved surface formed by the outer periphery of the limiting portion 320 can provide a guiding effect for the matching body 410, so that the matching body 410 can conveniently pass over the limiting portion 320 to complete the matching of the limiting portion 320 and the limiting hole 411. Of course, in other embodiments, the limiting portion 320 may have other shapes such as a frustum shape or a wedge shape.

In addition, in the present embodiment, the limiting hole 411 penetrates the fitting body 410 in the thickness direction of the fitting body 410. The limiting hole 411 is arranged to penetrate through the matching body 410, so that processing of the limiting hole 411 can be facilitated, and whether the limiting portion 320 is effectively matched with the limiting hole 411 can be confirmed conveniently. It should be appreciated that in other embodiments of the present application, the limiting aperture 411 may also be a blind aperture formed in the mating body 410, in other words, the limiting aperture 411 may be a slot formed in the mating body 410.

It should be noted that, since the overall thickness of the FPC assembly 200 is smaller, the overall thickness of the second connector 400 adapted to the FPC assembly 200 is also smaller, and the manner of forming the groove on the second connector 400 is more difficult, which greatly increases the manufacturing cost, and therefore, the limiting hole 411 is preferably disposed through the through hole of the mating body 410.

In this embodiment, in order to improve the mating stability of the mating body 410 and the first connector 300, the elastic portion 330 and the bearing body 310 together form a holding space 331; at least a portion of the mating body 410 is in an interference fit with the clasping space 331. In other words, in the case where the elastic portion 330 and the carrier body 310 jointly clamp the mating body 410, due to the abutting action of the mating body 410, the elastic portion 330 generates a certain elastic deformation, based on which, by the elastic restoring action of the elastic portion 330, the elastic portion 330 can apply an extrusion acting force to the mating body 410, thereby providing an effective clamping action to the mating body 410 to improve the mating stability of the mating body 410 and the first connector 300.

Optionally, in some embodiments of the present application, the elastic portion 330 includes a connecting portion 332 and a clamping portion 333; one side of the connection part 332 is connected to the side of the connection body 420 and is bent; the clamping portion 333 is disposed at the other side of the connecting portion 332, and the clamping portion 333 and the carrying body 310 form a clamping space 331. The connection portion 332 may be regarded as a structure rolled up from both sides of the carrier body 310 such that the clamping portion 333 can be located above the carrier body 310, thereby forming a clamping space 331 for clamping the second connector 400 together with the carrier body 310. It should be appreciated that in other embodiments of the present application, the connecting portion 332 may also extend along a straight path, thereby making the elastic portion 330 generally L-shaped, so that the clamping portion 333 may be located above the carrying body 310 to form the holding space 331 together with the carrying body 310.

In addition, to facilitate the clamping action provided by the elastic portion 330 to the second connector 400, the clamping portion 333 may optionally extend away from the connecting portion 332 toward the bearing body 310, so that the clamping portion 333 is inclined with respect to the bearing body 310. With the mating body 410 penetrating between the resilient portion 330 and the carrier body 310, the clamping portion 333 may at least abut against the mating body 410 through an end remote from the connecting portion 332 to provide a clamping action to the mating body 410. Of course, when the thickness of the mating body 410 is sufficient, the mating body 410 may be integrally attached to the mating body 410 by the clamping portion 333, and the clamping action may be integrally provided to the mating body 410 by the clamping portion 333.

In other embodiments of the present application, to prevent the clamping portion 333 from scratching or damaging the mating body 410, the clamping portion 333 may be bent away from the end of the connecting portion 332 to form an arc-shaped supporting surface (not shown), and the clamping portion 333 may be supported on the mating body 410 through the arc-shaped supporting surface, so as to prevent the clamping portion 333 from scratching or damaging the mating body 410. Of course, the setting of the abutment surface may be omitted.

In the present embodiment, in order to improve the mating stability of the mating body 410 and the first connector 300, the elastic portion 330 is plural; the at least two elastic portions 330 are respectively disposed on two opposite sides of the carrying body 310. In other words, the at least two elastic portions 330 provide the clamping action to the mating body 410, so as to increase the clamping force applied to the mating body 410, thereby increasing the mating stability of the mating body 410 and the first connector 300.

In addition, since the at least two elastic parts 330 are respectively disposed at both sides of the carrier body 310, a limiting effect can be provided to the second connector 400 at least through the two elastic parts 330 to limit the deflection of the mating body 410 toward both sides of the carrier body 310, in other words, the two connecting parts 332 can provide a limiting effect to the mating body 410 from both sides of the mating body 410 to ensure the assembling stability of the mating body 410.

It should be understood that in other embodiments of the present application, the number of the elastic portions 330 may be three, four or more. Of course, in other embodiments, the number of the elastic portions 330 may be one.

In addition, referring to fig. 6 in combination, in order to facilitate the insertion of the mating body 410 between the elastic portion 330 and the carrier body 310, the end of the mating body 410 is at least partially formed in a gradually reduced width state. For example, the end of the mating body 410 is semi-circular. For another example, the end of the mating body 410 is trapezoidal. For another example, the end of the mating body 410 is triangular or the like.

In the present embodiment, in order to improve the safety of the mating body 410, the mating body 410 includes a mating portion 412 and a weak portion 413; one end of the weak portion 413 is connected to the connection body 420, the fitting portion 412 is disposed at the other end of the weak portion 413, and the width of the weak portion 413 is smaller than that of the fitting portion 412. The weak portion 413 is easily fused under the condition of excessive current, so that the electrical connection relationship between the FPC member 200 and the bus bar 100 is timely disconnected when the current in the FPC member 200 is excessive, and the safety is improved. In other words, the weak portion 413 may be regarded as a fuse formed in the mating body 410.

In addition, at least part of the mating portion 412 is clamped between the elastic portion 330 and the carrier body 310; the engaging portion 412 is detachably engaged with the stopper portion 320. In other words, the engaging portion 412 is configured to engage with the elastic portion 330 and the limiting portion 320 as a structure engaging with the first connector 300, that is, the limiting hole 411 is formed in the engaging portion 412.

In the present embodiment, the first connector 300 may be fixedly connected to the bus bar 100 by laser welding or riveting, etc.; of course, the first connector 300 may also be integrally formed with the bus bar 100. In addition, the second connector 400 may be fixedly connected to the FPC member 200 by welding or riveting; of course, the second connector 400 may also be integrated on the FPC member 200 in an integrally formed manner.

In this embodiment, the second connector 400 may be made of nickel or aluminum.

In summary, the collection assembly 11 and the energy storage device 10 provided in the embodiments of the present application may implement the connection between the bus bar 100 and the FPC member 200 through the assembly of the first connector 300 and the second connector 400; at least a portion of the engaging body 410 is clamped between the elastic portion 330 and the carrier body 310, and at the same time, the engaging body 410 is detachably connected to the first connector 300 by the detachable engagement of the engaging body 410 with the limiting portion 320. After the FPC assembly 200 is scrapped, the connection relationship between the first connector 300 and the second connector 400 can be directly released, so that the FPC assembly 200 can be disassembled, and the replacement of the FPC assembly 200 can be easily completed. Based on this, the technical problem that the replacement is inconvenient after the FPC member 200 is scrapped in the prior art can be solved.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model.
