These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] The battery management system of the related technology includes a data acquisition mechanism, which includes a fixing component, multiple nickel plates and multiple pressure blocks. The fixing component is used to mount the circuit board, and the pressure blocks are fixed on the fixing component. The pressure blocks press the nickel plates on the fixing component, and the nickel plates are electrically connected to the circuit board, so that the nickel plates can transmit the battery's operating parameters to the processing unit on the circuit board.

[0046] However, when multiple nickel plates collect parameters from batteries of different quantities and locations, the specifications of the circuit boards will be different. The pressure block is fixed on the fixing component, making it difficult to adjust the position of the nickel plates, thereby reducing the applicability of the fixing component to circuit boards of different specifications.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Combination Figures 1 to 5 This application provides a data collection mechanism, including:

[0049] Fixing component 100, used for mounting circuit boards;

[0050] Multiple acquisition components 200 are electrically connected to the circuit board and are used to transmit the battery's operating parameters to the circuit board.

[0051] A first adjustment component 300 is disposed on a fixed component 100. The first adjustment component 300 is used to drive at least one acquisition component 200 to move in order to adjust the distance between the acquisition component 200 and the fixed component 100.

[0052] In this embodiment, the first adjustment component 300 is used to drive multiple acquisition components 200 to move simultaneously; the acquisition component 200 is a nickel sheet, which has excellent conductivity and welding performance, and can be well bonded with other metal materials of the battery, making it less prone to cracking or weak welding. Furthermore, the nickel sheet ensures stable current transmission in the battery connection, and the reliability of the welding point is also higher; in other embodiments, the nickel sheet can be replaced with an iron-chromium-aluminum alloy or a copper alloy, etc.

[0053] In this application, by adopting the first adjustment component 300, when circuit boards of different thicknesses are fixed on the fixing component 100, the first adjustment component 300 can adjust the distance between the multiple acquisition components 200 and the fixing component 100, thereby adjusting the distance between the acquisition components 200 and the circuit boards on the fixing component 100, so that the acquisition components 200 can be electrically connected to circuit boards of different thicknesses, thereby enabling the acquisition components 200 to transmit the battery's operating parameters to circuit boards of different thicknesses, improving the applicability of the acquisition mechanism.

[0054] Combination Figures 1 to 5 The first adjustment component 300 includes:

[0055] A sliding plate 310 is slidably disposed on the fixed component 100 in a direction that is close to or away from the fixed component 100, and multiple acquisition components 200 are disposed on the sliding plate 310.

[0056] The first adjusting member 320 is disposed on the fixed assembly 100 and is used to fix the sliding plate 310 to the sliding position.

[0057] In this embodiment, the sliding plate 310 is a cuboid; in other embodiments, the shape of the sliding plate 310 can be adapted as needed, for example, the sliding plate 310 can be set as a cube.

[0058] In this application, by setting multiple acquisition components 200 on the sliding plate 310, the first adjusting member 320 can fix the sliding plate 310 to the sliding position, thereby causing the sliding plate 310 to drive the multiple acquisition components 200 to be fixed to the sliding position. By using the sliding plate 310, the multiple acquisition components 200 can be adjusted simultaneously, thus eliminating the need to adjust the multiple acquisition components 200 separately, improving the convenience of adjusting the multiple acquisition components 200.

[0059] Combination Figures 1 to 5 The fixing component 100 includes a base 110 and a guide seat 120. The base 110 is used to fix the circuit board. The guide seat 120 is provided on the base 110 and at both ends of the sliding plate 310. The sliding plate 310 is slidably disposed on the guide seat 120.

[0060] In this embodiment, the base 110 is a cuboid, the width of the sliding plate 310 is smaller than the width of the base 110, the sliding plate 310 is arranged along the length of the base 110, and the sliding direction of the sliding plate 310 is arranged along the plane perpendicular to the base 110. Each guide seat 120 is detachably connected to the base 110 by four bolts. In other embodiments, the sliding direction of the sliding plate 310 can also be tilted towards the base 110, so that the height and position of the acquisition component 200 can be adjusted simultaneously.

[0061] In this application, by adopting the base 110 and the guide seat 120, the guide seat 120 can guide the sliding plate 310 to slide, preventing the sliding plate 310 from deviating when sliding towards or away from the base 110, thereby indirectly improving the positional accuracy of the sliding plate 310 when driving the multiple acquisition components 200 to adjust.

[0062] Combination Figures 1 to 5 Each of the two guide seats 120 has a sliding groove 121 on its opposite surface. The sliding groove 121 is used to accommodate at least part of the sliding plate 310. The sliding plate 310 is slidably mounted on the guide seat 120 through the sliding groove 121.

[0063] In this embodiment, the slide groove 121 has a U-shaped cross-section. Along the direction perpendicular to the plane where the base 110 is located, both ends of the slide groove 121 pass through the guide seat 120. The two slide grooves 121 are used to accommodate the ends of the sliding plate 310. In other embodiments, the shape of the slide groove 121 can be adjusted as needed. For example, the cross-section of the slide groove 121 can be set to a T-shape or a dovetail shape, and the ends of the sliding plate 310 can be matched with the T-shaped or dovetail-shaped slide groove 121.

[0064] In this application, by adopting the arrangement of the slide groove 121, the slide groove 121 can further guide the movement of the sliding plate 310 and prevent the sliding plate 310 from deviating during sliding.

[0065] Combination Figures 1 to 5 The first adjusting member 320 includes a first bolt 322. The guide seat 120 is provided with a first strip hole 321. The first bolt 322 is used to pass through the first strip hole 321 and is threadedly connected to the sliding plate 310 to fix the sliding plate 310 to the guide seat 120.

[0066] In this embodiment, each guide seat 120 is provided with two first strip holes 321 and two first bolts 322. The two first bolts 322 are inserted into the two first strip holes 321 in a corresponding manner. The two first strip holes 321 are parallel to each other and spaced apart. The first strip holes 321 are arranged along the plane perpendicular to the base 110.

[0067] In this application, when it is necessary to adjust the distance between the sliding plate 310 and the base 110, the sliding plate 310 is moved on the guide seats 120 on both sides, so that the sliding plate 310 moves closer to or away from the base 110. This causes the sliding plate 310 to move multiple acquisition components 200 closer to or away from the circuit board on the base 110, thereby adjusting the distance between the multiple acquisition components 200 and the circuit board. By passing the shank of the first bolt 322 through the first strip hole 321 and inserting and threading the shank of the first bolt 322 onto the sliding plate 310, the head of the first bolt 322 abuts against the guide seat 120. The sliding plate 310 is fixed in the slid position by the friction between the head of the first bolt 322 and the guide seat 120.

[0068] In other embodiments, the first bolt 322 can be replaced by a spring. By connecting one end of the spring to the sliding plate 310 and passing the spring through the first strip hole 321, an abutment plate is provided at the end of the spring away from the sliding plate 310, so that the abutment plate abuts against the guide seat 120 by the elastic force of the spring, thereby also achieving the position fixation of the sliding plate 310.

[0069] Combination Figures 1 to 5 The acquisition mechanism also includes a second adjustment component 400, which is disposed on the sliding plate 310. The second adjustment component 400 is used to drive the acquisition component 200 to move, so as to adjust the spacing between adjacent acquisition components 200.

[0070] In this application, by adopting the second adjustment component 400, the second adjustment component 400 can adjust the spacing between adjacent acquisition components 200, so that acquisition components 200 at different positions can be used on circuit boards of different lengths and electrically connected to different positions on the circuit board, thereby further improving the applicability of acquisition components 200.

[0071] Combination Figures 1 to 5 The second adjustment component 400 includes multiple connectors 410 and a second adjustment component 420. The multiple connectors 410 are slidably disposed on the sliding plate 310. Multiple acquisition components 200 are disposed on the multiple connectors 410 in a corresponding manner. The multiple connectors 410 are each provided with a second adjustment component 420. The second adjustment component 420 is used to fix the connectors 410 to the slid position.

[0072] In this application, by employing a connector 410 and a second adjusting member 420, the connector 410 can fix the acquisition component 200. By moving the connector 410 on the sliding plate 310, the connector 410 moves the acquisition component 200, thereby adjusting the position of the acquisition component 200. The second adjusting member 420 can fix the connector 410, so that the connector 410 moves the acquisition component 200 to be fixed in the adjusted position. This allows acquisition components 200 at different positions to be electrically connected to different positions on circuit boards of different lengths, improving the applicability of the acquisition mechanism. By employing multiple connectors 410, the positions of multiple acquisition components 200 can be adjusted separately, thereby facilitating the electrical connection of multiple acquisition components 200 to different positions on the circuit board.

[0073] Combination Figures 1 to 5 The second adjusting member 420 includes a second bolt 422 and a first nut 423. The sliding plate 310 is provided with a second strip hole 421. The second bolt 422 passes through the connecting member 410 and the second strip hole 421. The first nut 423 is sleeved and threadedly connected to the second bolt 422.

[0074] In this embodiment, the second strip hole 421 is provided along the length direction of the sliding plate 310.

[0075] In this application, when it is necessary to fix the connector 410, the second bolt 422 is inserted into the connector 410 and the second slot 421, causing the connector 410 to move on the second slot 421, so that the connector 410 drives the acquisition component 200 to move to the designated position. The first nut 423 is sleeved and threaded onto the second bolt 422, so that the head of the second bolt 422 and the first nut 423 abut against the opposite sides of the connector 410 and the sliding plate 310, so that the connecting frame is fixed to the sliding position. The use of the second bolt 422 and the first nut 423 has a simple structure and improves the strength of fixing the connector 410.

[0076] In other embodiments, the second bolt 422 can be replaced with a spring. By inserting the spring through the connector 410 and the second slot 421, and providing abutment plates at both ends of the spring, the two abutment plates abut against the opposite sides of the connector 410 and the sliding plate 310 respectively by the elastic force of the spring, so that the connecting frame can also be fixed to the slid position.

[0077] Combination Figures 1 to 5 The sliding plate 310 has a receiving groove 311 on the side facing the base 110, which is used to receive the first nut 423.

[0078] In this embodiment, the two ends of the receiving groove 311 along the length direction of the sliding plate 310 are closed, the side of the receiving groove 311 facing the sliding plate 310 is open, and the two sides of the receiving groove 311 along its length direction are open.

[0079] In this application, by adopting the arrangement of the receiving groove 311, it is convenient for the operator to turn the first nut 423 through the receiving groove 311, and the operating space is provided for turning the first nut 423.

[0080] Combination Figures 1 to 5 The connector 410 includes a first pressing block 411 and a second pressing block 412. The first pressing block 411 is disposed on the second pressing block 412, and the second pressing block 412 is slidably disposed on the sliding plate 310. The second bolt 422 passes through both the first pressing block 411 and the second pressing block 412. The acquisition component 200 is disposed between the first pressing block 411 and the second pressing block 412.

[0081] In this embodiment, the first pressing block 411 and the second pressing block 412 have the same shape. Both the first pressing block 411 and the second pressing block 412 are cuboids and are arranged along the width direction of the sliding plate 310.

[0082] In this application, when the first nut 423 is sleeved and threaded onto the second bolt 422, the second bolt 422 passes through both the first pressure block 411 and the second pressure block 412, allowing the acquisition component 200 to be pressed between the first pressure block 411 and the second pressure block 412. This fixes the acquisition component 200 to the first pressure block 411 and the second pressure block 412, and the second bolt 422 can fix the first pressure block 411 and the second pressure block 412 to their sliding positions on the sliding plate 310. Thus, the second bolt 422 can not only fix the acquisition component 200, but also fix the positions of the first pressure block 411 and the second pressure block 412, improving the convenience and strength of fixing the acquisition component 200, the first pressure block 411, and the second pressure block 412.

[0083] In other embodiments, the connector 410 can also be replaced by a gripper. The gripper clamps the clamping assembly and the second bolt 422 fixes the gripper to the slidable position, which can also achieve the fixing and position adjustment of the clamping assembly.

[0084] Combination Figures 1 to 5 The first pressure block 411 and the second pressure block 412 are each provided with a third strip hole 413, which is perpendicular to the second strip hole 421. The second strip hole 421 is used for the shank of the second bolt 422 to pass through.

[0085] In this application, by adopting the third strip hole 413, which is perpendicular to the second strip hole 421, the first pressing block 411 and the second pressing block 412 can move on the second bolt 422 through the third strip hole 413. This allows the first pressing block 411 and the second pressing block 412 to move along the length direction perpendicular to the second strip hole 421, causing the first pressing block 411 and the second pressing block 412 to move closer to or away from the circuit board. Consequently, the first pressing block 411 and the second pressing block 412 drive the acquisition component 200 closer to or away from the circuit board, making the acquisition component 200 suitable for circuit boards of different widths. The acquisition mechanism can adapt to circuit boards of different thicknesses, lengths, and widths, further improving the applicability of the acquisition mechanism.

[0086] Combination Figures 1 to 5 The acquisition mechanism also includes a fixed base 500 and a third adjustment component 600. The fixed base 500 is mounted on the base 110 and multiple acquisition components 200 are mounted on the fixed base 500. The third adjustment component 600 is mounted on the fixed base 500 and is used to drive the acquisition components 200 to move in order to adjust the spacing between adjacent acquisition components 200.

[0087] In this embodiment, the fixed base 500 and the sliding plate 310 are respectively arranged on opposite sides of the circuit board. The fixed base 500 and the sliding plate 310 have the same length. The number of acquisition components 200 on the fixed base 500 and the sliding plate 310 can be adjusted as needed. The fixed base 500 is fixed to the base 110 by bolts.

[0088] In this application, by employing a fixed base 500 and setting multiple acquisition components 200 on the fixed base 500, in conjunction with the base 110 and the first adjustment component 300, the multiple acquisition components 200 on the base 110 and the fixed base 500 are suitable for situations where the heights on both sides of the circuit board are different, thereby further improving the applicability of the sampling mechanism. By employing a third adjustment component 600, the third adjustment component 600 can adjust the spacing between adjacent acquisition components 200 on the fixed base 500, so that the multiple acquisition components 200 on the fixed base 500 can be used for circuit boards of different lengths, thereby improving the applicability of the multiple acquisition components 200 on the fixed base 500.

[0089] Combination Figures 1 to 5 The third adjustment component 600 includes multiple connecting plates 610 and a third adjustment component 620. The multiple connecting plates 610 are slidably mounted on the fixed base 500. The acquisition component 200 is disposed between the connecting plates 610 and the fixed base 500. The third adjustment component 620 is used to fix the connecting plates 610 to the slidable position.

[0090] In this application, by sliding the connecting plate 610 onto the fixed base 500, the fixed base 500 can guide the sliding of the connecting plate 610, preventing the connecting plate 610 from shifting during movement. Since the acquisition component 200 is located between the connecting plate 610 and the fixed base 500, preventing the connecting plate 610 from shifting also prevents the connecting plate 610 from causing the acquisition component 200 to shift. By using the third adjusting member 620, the connecting plate 610 can be fixed in the slidable position, so that the connecting plate 610 fixes the acquisition component 200. This eliminates the need to fix the connecting plate 610 separately and then fix the acquisition component 200 separately, thereby improving the convenience of adjusting and fixing the position of the acquisition component 200 on the fixed base 500.

[0091] Combination Figures 1 to 5 The third adjusting component 620 includes a third bolt 622 and a second nut 623. The fixing base 500 is provided with a fourth strip hole 621. The third bolt 622 passes through the connecting plate 610 and the third strip hole 413. The second nut 623 is sleeved and threadedly connected to the third bolt 622.

[0092] In this embodiment, the fourth strip hole 621 is parallel to the second strip hole 421.

[0093] In this application, when the second nut 623 is sleeved and threaded onto the third bolt 622, the third bolt 622 passes through both the connecting plate 610 and the third slotted hole 413, allowing the acquisition component 200 to be pressed between the connecting plate 610 and the fixing seat 500. This fixes the acquisition component 200 to the connecting plate 610 and the fixing seat 500, and the third bolt 622 can fix the connecting plate 610 to the position after sliding on the fixing seat 500. Thus, the third bolt 622 can not only fix the acquisition component 200, but also fix the position of the connecting plate 610, improving the convenience and strength of fixing the acquisition component 200 and the connecting plate 610.

[0094] Combination Figures 1 to 5 The fixing seat 500 has a groove 510 on the side opposite to the base 110, which is used to accommodate the second nut 623.

[0095] In this application, by adopting the groove 510, it is convenient for the operator to turn the second nut 623 through the groove 510, and the operation space is provided for turning the second nut 623.

[0096] This application also provides a battery management system, including a housing and a data acquisition mechanism of any of the above embodiments disposed on the housing.

[0097] The specific structure of the data acquisition mechanism has been described in detail in the above embodiments and will not be repeated here.

[0098] This application also provides a battery pack, including a frame and a battery management system disposed on the frame.

[0099] This application also provides an electrical device, including a device body and a battery pack disposed on the device body.

[0100] In this embodiment, the electrical equipment is a car. In other embodiments, the electrical equipment can also be replaced by an energy storage system, industrial automation equipment, or aerospace equipment, etc.

[0101] The electrical equipment provided in this application, by setting up a data acquisition mechanism, when the circuit board is placed on the base 110, drives the sliding plate 310 to move within the sliding grooves 121 of the guide seats 120 on both sides, thereby causing the sliding plate 310 to move closer to or further away from the base 110. A first bolt 322 passes through the first slot 321, and the shank of the first bolt 322 is inserted and threaded into the sliding plate 310, causing the head of the first bolt 322 to abut against the guide seat 120, thereby fixing the sliding plate 310. Multiple nickel sheets on plate 10 can be electrically connected to circuit boards of different thicknesses. By moving the second pressure block 412 on the sliding plate 310, the second pressure block 412 causes the second bolt 422 to move within the second slot 421. By moving the first pressure block 411 and the second pressure block 412, the first pressure block 411 and the second pressure block 412 move through the third slot 413 on the second bolt 422, thereby causing the nickel sheet between the first pressure block 411 and the second pressure block 412 to move along the length of the second slot 421. The direction and length direction perpendicular to the second strip hole 421 are moved. By threading the first nut 423 onto the second bolt 422, the second bolt 422 and the first nut 423 can fix the first pressure block 411 and the second pressure block 412 to the slid position. This allows multiple nickel plates on the sliding plate 310 to be electrically connected to different positions of circuit boards of different widths and lengths. By driving the connecting plate 610 to move on the fixed base 500, the connecting plate 610 drives the third bolt 622 to move in the fourth strip hole 621, thereby adjusting the spacing between adjacent nickel plates on the fixed base 500. By threading the second nut 623 onto the third bolt 622, the connecting plate 610 is fixed to the slid position. This allows multiple nickel plates on the fixed base 500 to be suitable for circuit boards of different lengths. By cooperating with the multiple nickel plates on the sliding plate 310, multiple nickel plates on both sides can be used when the heights of the opposite sides of the circuit board are different, thereby improving the applicability of the acquisition mechanism.
