That is, the existing battery sampling assembly is mainly connected by welding. This connection method is prone to welding defects such as cold welding, slag inclusion, incomplete fusion, and false welding, which leads to the risk of circuit non-conduction or poor conduction, and poor connection reliability; and when the collection circuit board causes the battery pack to need after-sales service due to collection abnormalities, it is usually impossible to replace the collection circuit board and the entire battery pack can only be scrapped, and the after-sales cost remains high; further, in the production process, the collection metal sheets have various specifications, and the mold tooling cost and the production process management error prevention cost are high.

[0017] Beneficial effects of the utility model:

[0018] (1) By using a connection module to detachably connect the collection metal sheet and the collection circuit board, welding defects such as cold welding, slag inclusion, incomplete fusion, and false welding that occur in the prior art by welding can be effectively avoided, and the connection reliability is good; and the connection module can quickly and conveniently realize the connection between the collection metal sheet and the collection circuit board, and the process materials such as welding at the collection point and gluing at the solder joints and the mold tooling are eliminated in the process, thereby improving efficiency; and the collection point of the collection circuit board uses a connection module of uniform specifications to connect with the collection metal sheet, which has high versatility and saves the cost of repeated development of mold tooling; further, when the battery sampling assembly needs after-sales service due to a collection abnormality of the collection circuit board, the collection circuit board can be conveniently and quickly replaced without damage for repair, greatly reducing the after-sales cost.

[0019] (2) When the collecting metal sheet is accurately assembled in the positioning groove of the base, there is a first gap and / or a second gap between the positioning groove and the collecting metal sheet.

[0021] (4) By arranging a reinforcing plate above the acquisition circuit board, the strength of the contact area between the acquisition circuit board and the acquisition metal sheet can be enhanced, thereby ensuring the flatness of the contact area and preventing plastic deformation due to excessive pressing force; and the thickness of the reinforcing plate matched therewith can be adjusted according to the thickness of a single arm in the acquisition circuit board, thereby keeping the total thickness of the arm and the reinforcing plate at different positions unchanged, thereby ensuring that the entire acquisition circuit board is arranged more flatly.

DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0038] like Figures 1 to 13 As shown, this embodiment provides a non-destructively replaceable welding-free new energy battery sampling assembly, including a bracket 1, on which a collection circuit board 2, a plurality of conductive bars 4 and a plurality of collection metal sheets 3 are arranged, one end of each of the collection metal sheets 3 is connected to one of the conductive bars 4; the other end of each of the collection metal sheets 3 is detachably connected to the collection circuit board 2 via a connection module 5.

[0039] Specifically, the acquisition circuit board 2 is provided with a plurality of positioning through holes 22, and the middle position of the bracket 1 is provided with a plurality of positioning posts 14 corresponding to the position of the positioning through holes 22 of the acquisition circuit board 2. The acquisition circuit board 2 is sleeved on the plurality of positioning posts 14 to realize the rapid installation of the acquisition circuit board 2 on the bracket 1; a plurality of installation positioning grooves 12 are respectively provided on both sides of the bracket 1, the conductive bar 4 is installed in the installation positioning grooves 12, and at least two pressing blocks 13 for fixing the conductive bar 4 are provided on the surrounding side of the installation positioning grooves 12, and the upper end of the pressing block 13 is provided with a guiding inclined surface 131; the positioning posts 14, the installation positioning grooves 12 and the pressing buckle are integrally injection molded with the bracket 1. The acquisition circuit board 2 includes a main body 23, and arm parts 24 located on both sides of the main body 23 and connected to the main body 23, and the other end of each acquisition metal sheet 3 is detachably connected to one of the arm parts 24 through a connecting module 5.

[0040] In this embodiment, the collection metal sheet 3 and the collection circuit board 2 are detachably connected by using a connection module 5, which can effectively avoid welding defects such as cold welding, slag inclusion, incomplete fusion, and false welding that occur in the prior art when welding is used for connection, and the connection reliability is good; and the connection module 5 can quickly and conveniently realize the connection between the collection metal sheet 3 and the collection circuit board 2, and the process materials such as welding at the collection point position and gluing at the solder joints and the mold tooling are eliminated in the process, thereby improving efficiency; and the collection point of the collection circuit board 2 uses a connection module 5 of uniform specifications to connect with the collection metal sheet 3, which has high versatility and saves the cost of repeated development of mold tooling; further, when the battery sampling assembly needs after-sales service due to collection abnormalities in the collection circuit board 2, the collection circuit board 2 can be replaced quickly and conveniently without damage for repair, greatly reducing the after-sales cost.

[0041] Further, the connection module 5 includes a base 6 fixedly connected to the bracket 1, an upper cover assembly 7 is connected to the base 6, and at least a portion of the upper cover assembly 7 can move relative to the base 6, the collection metal sheet 3 and the collection circuit board 2 are arranged between the base 6 and the upper cover assembly 7, and the upper cover assembly 7 cooperates with the base 6 to press the collection metal sheet 3 and the collection circuit board 2. In this embodiment, by setting at least a portion of the upper cover assembly 7 to be able to move relative to the base 6, the detachable connection between the collection metal sheet 3 and the collection circuit board 2 can be easily achieved.

[0042] Further, the upper cover assembly 7 includes a fixed upper cover 8 and a flip slide 9, the fixed upper cover 8 is connected to the base 6, guide rods 91 are respectively extended outward on both sides of the flip slide 9, and guide slots 81 for accommodating the guide rods 91 are respectively provided on both sides of the interior of the fixed upper cover 8, and the guide rods 91 can move forward and backward along the guide slots 81 and can rotate relative to the guide slots 81. Specifically, the fixed upper cover 8 is fixedly connected to the base 6 by means of snap connection, plug connection or fastener connection. The flip slide 9 is provided with an arc-shaped plug-in portion 93 at one end close to the fixed upper cover 8, and the inner side of the fixed upper cover 8 is provided with an arc-shaped receiving groove 84 corresponding to the arc-shaped plug-in portion 93; the guide rod 91 is cylindrical, and the guide groove 81 is elliptical, so that after the guide rod 91 is inserted into the guide groove 81, it can move forward and backward along the guide groove 81 and can rotate relative to the guide groove 81, so as to drive the arc-shaped plug-in portion 93 to enter or move out of the arc-shaped receiving groove 84 by moving forward and backward. When the flip slide 9 is rotated downward to press the collection metal sheet 3 and the collection circuit board 2 , the flip slide 9 moves backward to insert the arc-shaped plug-in portion 93 into the arc-shaped receiving groove 84, so that the arc-shaped receiving groove 84 limits the vertical position of the arc-shaped plug-in portion 93, ensuring that the flip slide 9 can press the collection metal sheet 3 and the collection circuit board 2, thereby ensuring the connection reliability; when the flip slide 9 rotates upward to leave the collection metal sheet 3 and the collection circuit board 2, the flip slide 9 moves forward to leave the arc-shaped plug-in portion 93 from the arc-shaped receiving groove 84, thereby releasing the position limit of the arc-shaped plug-in portion 93 by the arc-shaped receiving groove 84, ensuring that the flip slide 9 can be smoothly flipped upward for easy installation and disassembly. In addition, a first inclined surface 94 is provided on the upper end surface of the flip slide 9 close to the fixed upper cover 8, and a second inclined surface 85 is provided on the front end surface of the fixed upper cover 8 close to the flip slide 9. When the flip slide 9 rotates upward, the first inclined surface 94 leans against the second inclined surface 85, which can ensure that the angle between the lower surface of the flip slide 9 and the upper surface of the base 6 is at least 90°, which is convenient for inserting and removing the collection circuit board 2.

[0043] Further, the two sides of the fixed upper cover 8 are provided with first hooks or first slots 82 extending downward, and the two sides of the base 6 are provided with first slots or first hooks 61 matching therewith; the two sides of the flip slide cover 9 are provided with second hooks 92 or second slots extending downward, and the two sides of the base 6 are provided with second slots 62 or second hooks matching therewith. Specifically, the two sides of the fixed upper cover 8 are provided with first slots 82 extending downward, and the two sides of the base 6 are provided with first hooks 61 matching therewith. When installing, the fixed upper cover 8 is pressed downward toward the base 6 so that the first hook 61 is inserted into the first slot 82, so that the fixed upper cover 8 and the base 6 are fixedly connected. When disassembling, the first slot 82 is separated from the first hook 61, so that the fixed upper cover 8 and the base 6 are separated. The flip slide cover 9 is provided with second hooks 92 extending downward on both sides, and correspondingly, the base 6 is provided with matching second slots 62 on both sides. Similarly, when installing, the flip slide cover 9 is pressed downward toward the base 6 so that the second hooks 92 are inserted into the second slots 62, thereby achieving a fixed connection between the flip slide cover 9 and the base 6. When disassembling, the second hooks 92 are detached from the second slots 62, thereby achieving separation between the flip slide cover 9 and the base 6.

[0044] Furthermore, the second hook 92 includes a horizontal limit hook 921 and a vertical limit hook 922, and correspondingly, the second slot 62 includes a horizontal limit groove 621 and a vertical limit groove 622. Specifically, the horizontal limit hook 921 includes a plurality of first side surfaces arranged along the vertical direction, and the horizontal limit groove 621 includes a plurality of first inner side walls arranged along the vertical direction, and the first side surfaces cooperate with the first inner side walls to define the position of the second hook 92 in the horizontal direction; the vertical limit hook 922 includes a second side surface arranged along the horizontal direction, and the vertical limit groove 622 includes a second inner side wall arranged along the horizontal direction, and the second side surface cooperates with the second inner side wall to define the position of the second hook 92 in the vertical direction; therefore, the horizontal limit hook 921 and the vertical limit groove 622 are engaged with each other. The cooperation of the horizontal limit groove 621 and the cooperation of the vertical limit hook 922 with the vertical limit groove 622 realizes the limitation of the spatial position of the second hook 92, thereby limiting the end of the flip slide 9 away from the fixed upper cover 8; at the same time, due to the cooperation of the arc-shaped accommodating groove 84 and the arc-shaped plug-in portion 93, the end of the flip slide 9 close to the fixed upper cover 8 is limited, thereby realizing the precise limitation of the position of the flip slide 9, ensuring that the flip slide 9 is accurately pressed above the collection metal sheet 3 and the collection circuit board 2 without deviation, thereby ensuring the reliability of the connection between the collection metal sheet 3 and the collection circuit board 2.

[0045] Further, the base 6 is provided with a first positioning mechanism 63 for positioning the collection metal sheet 3 and a second positioning mechanism 64 for positioning the collection circuit board 2; the collection metal sheet 3 is provided with a first limiting mechanism 31 that cooperates with the first positioning mechanism 63, and the collection circuit board 2 is provided with a second limiting mechanism 21 that cooperates with the second positioning mechanism 64. Specifically, the first positioning mechanism 63 includes a positioning groove 633 and a plurality of vertical positioning protrusions 631 and / or lateral positioning protrusions 632 located in the positioning groove 633, and correspondingly, the first limiting mechanism 31 includes a plurality of limiting through holes 311 that cooperate with the vertical positioning protrusions 631 and / or lateral positioning grooves 312 that cooperate with the lateral positioning protrusions 632. When installing the collecting metal sheet 3, align the limiting through hole 311 on the collecting metal sheet 3 with the vertical positioning protrusion 631 and / or align the lateral positioning groove 312 with the lateral positioning protrusion 632, so as to accurately assemble the collecting metal sheet 3 in the positioning groove 633 of the base 6. After the collecting metal sheet 3 is installed, when the collecting metal sheet 3 is not subjected to external force, there is a first gap 634 between one end of the collecting metal sheet 3 located in the positioning groove 633 and the side wall of the positioning groove 633, and / or there is a second gap 635 between the bottom of the collecting metal sheet 3 and the top of the positioning groove 633. When the collecting metal sheet 3 is subjected to a downward pressing force, the collecting metal sheet 3 will undergo elastic deformation, and the first gap 634 and / or the second gap 635 provide sufficient space for the elastic deformation, thereby preventing the collecting metal sheet 3 from undergoing uncontrollable deformation due to insufficient elastic deformation space. In addition, the second positioning mechanism 64 includes a plurality of end positioning bosses 641 and / or side positioning bosses 642, and in order to make the structure more compact, the end positioning bosses 641 are arranged above the vertical positioning protrusions 631; correspondingly, the second limiting mechanism 21 includes a plurality of side limiting grooves 211 matched with the side positioning bosses 642. When installing the acquisition circuit board 2, align the end of the acquisition circuit board 2 with the end positioning bosses 641 and / or align the side limiting grooves 211 with the side positioning bosses 642, so that the acquisition circuit board 2 is accurately placed on the base 6.

[0046] Furthermore, the acquisition circuit board 2 is placed above the acquisition metal sheet 3, and one end of the acquisition metal sheet 3 connected to the acquisition circuit board 2 is bent to form a raised rib 32; the first limiting mechanism 31 includes a plurality of limiting through holes 311, and the plurality of limiting through holes 311 are arranged in sequence along the raised rib 32. Specifically, the collection metal sheets 3 located on both sides of the raised ribs 32 are bent downward by 1 to 10 degrees relative to the horizontal plane, preferably, by 4 to 5 degrees, so as to form a raised rib 32 at one end of the collection metal sheet 3 connected to the collection circuit board 2. The raised rib 32 protrudes in the direction of the collection circuit board 2 to ensure stable contact between the collection metal sheet 3 and the collection circuit board 2, and the bending angle cannot be too large to prevent stress concentration from occurring when the flip slide cover 9 is pressed down and tightened. Long-term stress concentration will cause metal fatigue to form micro cracks and fractures; at the same time, the bottom surface of the positioning groove 633 in the base 6 also forms an upward protrusion accordingly to match the shape of the collection metal sheet 3 and better carry the collection metal sheet 3; further, the limiting through holes 311 are arranged in sequence along the raised ribs 32, and by reasonably arranging the positions of the raised ribs 32 and the limiting through holes 311, not only the structure is made more compact, but also the stress at the bending part of the collection metal sheet 3 is helped to be released along the limiting through holes 311, further avoiding the occurrence of stress concentration.

[0047] Furthermore, a reinforcing plate 10 is also provided above the acquisition circuit board 2, and a third limiting mechanism 101 is provided on the reinforcing plate 10 to cooperate with the second positioning mechanism 64. Specifically, the second positioning mechanism 64 includes a plurality of end positioning bosses 641 and / or side positioning bosses 642, and in order to make the structure more compact, the end positioning bosses 641 are provided above the vertical positioning protrusions 631; correspondingly, the third limiting mechanism 101 includes a plurality of side limiting grooves to cooperate with the side positioning bosses 642. The reinforcing plate 10 can be made of materials such as PI (polyimide) and FR (epoxy resin glass fiber board). By arranging the reinforcing plate 10 above the acquisition circuit board 2, the strength of the contact area between the acquisition circuit board 2 and the acquisition metal sheet 3 can be enhanced, thereby ensuring the flatness of the contact area and preventing plastic deformation due to excessive pressing force; and the thickness of the reinforcing plate 10 matched therewith can be adjusted according to the thickness of a single arm 24 in the acquisition circuit board 2, thereby keeping the total thickness of the arm 24 and the reinforcing plate 10 at different positions unchanged, thereby ensuring that the entire acquisition circuit board 2 is arranged more flatly.

[0048] Furthermore, at least part of the surface of the upper cover assembly 7 in contact with the collection metal sheet 3 and / or the collection circuit board 2 is provided with a compression rib 11 downward. Specifically, the lower surfaces of the fixed upper cover 8 and the flip slide cover 9 in the upper cover assembly 7 are provided with compression ribs 11, and there are several compression ribs 11 and they are arranged at intervals; when the upper cover assembly 7 is pressed downward, the compression strength of the collection metal sheet 3 and / or the collection circuit board 2 at the position with the compression rib 11 is greater than that at the position without the compression rib 11. Therefore, by providing the compression rib 11, the pressing force on the collection metal sheet 3 and / or the collection circuit board 2 can be effectively increased, thereby ensuring the connection strength of the collection metal sheet 3 and the collection circuit board 2.

Simultaneously assemble the collection metal sheet 3 into the base 6. Specifically, align the limiting through hole 311 on the collection metal sheet 3 with the vertical positioning protrusion 631 and / or align the lateral positioning groove 312 with the lateral positioning protrusion 632, so as to accurately assemble the collection metal sheet 3 into the positioning groove 633 of the base 6. At this time, there is a first gap 634 between one end of the collection metal sheet 3 located in the positioning groove 633 and the side wall of the positioning groove 633, and / or there is a second gap 635 between the bottom of the collection metal sheet 3 and the top of the positioning groove 633.
