Description

Technical Field

[0001] This invention relates to a fixing component and a detection component. Background Technology

[0002] There are two main charging methods for existing electric vehicles: direct charging and fast-swapping. Direct charging requires the installation of charging stations, but it takes a long time and is less efficient. Fast-swapping, on the other hand, can meet the power needs of electric vehicles by replacing the battery pack, thus reducing the charging time significantly compared to direct charging.

[0003] In existing quick-swap electric vehicles, a quick-swap bracket is typically installed at the bottom of the vehicle to lock the battery pack to the vehicle. For example... Figure 1 The diagram shows a structural schematic of the quick-change bracket 2 and the battery pack 1 when they are separated. The battery pack 1 is provided with a battery end electrical connector 11, and the quick-change bracket 2 is provided with a quick-change electrical connector 20 that connects to the battery end electrical connector 11. Unlike the high and low voltage plugs of the direct-charge battery pack, the low voltage signal port of the quick-change battery pack does not have a manual plug-in port reserved in the structure of the battery end electrical connector. Therefore, when the quick-change battery pack is removed from the electric vehicle or for a single battery pack, the testing equipment cannot directly connect to the port of the battery pack to test the battery pack performance.

[0004] In existing technologies, battery packs are typically mounted on quick-change brackets on electric vehicles, such as... Figure 2 The diagram shows a partial view of the electrical connector when the battery pack 1 is mounted on the quick-change bracket 2. The battery pack requires additional mounting equipment to be placed on the quick-change bracket in order to test the module information and battery charging / discharging function, making the battery pack testing process complex and unsuitable for on-site testing. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the complex testing process of battery packs in the prior art, and to provide a fixing component and a testing component.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A fixing component is provided for detachably connecting a detection unit to a unit to be detected.

[0008] The fixing component includes a connecting part and a limiting part. The connecting part is rotatably connected to the part to be tested. The limiting part is connected to the testing part. When the testing part is connected to the part to be tested, the limiting part is used to prevent the testing part from detaching from the part to be tested.

[0009] In this solution, the fixing component can be detachably connected to the part to be tested, thereby connecting the testing unit to the part to be tested during testing. The connecting part is rotatably connected to the part to be tested, and the fixing component as a whole can rotate relative to the part to be tested. This allows the limiting part to rotate to a certain position and restrict the position of the testing unit, preventing the testing unit from detaching and ensuring a reliable connection between the testing unit and the part to be tested. Therefore, for battery packs removed from electric vehicles, or individual battery packs, this fixing component can reliably and detachably connect the testing unit to the electric vehicle, making testing flexible and convenient, simplifying the testing process, and facilitating on-site testing.

[0010] Preferably, the connecting portion includes an insert for insertion into a matching portion on the part to be detected, and for preventing the fixing component from disengaging from the part to be detected.

[0011] In this solution, the insert can be inserted into the matching part on the part to be tested, preventing the fixing component from detaching from the part to be tested, thereby avoiding loosening or misalignment of the connection between the testing part and the part to be tested, making the connection between the testing part and the part to be tested more reliable.

[0012] Preferably, the matching part includes a pre-drilled hole, and the insert includes a retaining plate, at least a portion of which has an outer diameter larger than the inner diameter of the pre-drilled hole.

[0013] In this solution, by adopting the above structure, the card plate is inserted into the reserved hole at a certain angle. When the card plate is fully inserted into the reserved hole, since at least part of the outer diameter of the card plate is larger than the diameter of the reserved hole, it can be restricted to one side of the reserved hole, thereby enabling the connecting part and the part to be tested to be detachably connected. Moreover, this connection method is simple and easy to operate.

[0014] Preferably, the card plate is a waist-shaped plate, the length of the card plate is greater than the diameter of the reserved hole, and the width of the card plate is less than the diameter of the reserved hole.

[0015] In this solution, the card is designed as an oblong plate, so that the length of the card is greater than the diameter of the reserved hole, thus enabling the card to be inserted into the reserved hole.

[0016] Preferably, the connecting part further includes a fixed shaft, the two ends of which are respectively connected to the limiting part and the insert.

[0017] In this solution, the limiting part and the insert can be connected by a fixed shaft, and there can also be a gap between the limiting part and the insert to reserve space for the arrangement of the detection part.

[0018] Preferably, the connecting part includes a first elastic member and a movable member, the movable member being axially movable along the fixed shaft, the first elastic member being used to abut the movable member against the part to be tested, and the movable member and the insert being clamped on both sides of the reserved hole.

[0019] In this solution, after the insert is inserted into the pre-drilled hole, the movable part can be pressed against the part to be tested by the first elastic element. On the one hand, this allows the fixed shaft to be perpendicular to the wall surface where the pre-drilled hole is located to be aligned. On the other hand, it allows the movable part to make effective surface contact with the wall surface of the part to be tested where the pre-drilled hole is located, and is clamped with the insert on both sides of the wall where the pre-drilled hole is located, so that the fixing assembly is stably connected to the part to be tested, and ensures that the testing part and the part to be tested are in an effective contact state.

[0020] Preferably, the movable component includes a retaining ring, both the first elastic element and the retaining ring are sleeved on the fixed shaft, and the retaining ring is located between the insert and the first elastic element; the outer diameter of the retaining ring is larger than the diameter of the reserved hole.

[0021] In this design, both the first elastic element and the fixing ring are sleeved on the fixed shaft, with the fixing ring positioned between the insert and the first elastic element. Both ends of the first elastic element can contact the limiting part and the fixing ring. Therefore, when the fixing assembly is connected to the part to be tested, the first elastic element can apply force to the fixing ring. Furthermore, the outer diameter of the fixing ring is larger than the diameter of the pre-drilled hole, allowing the fixing ring to abut against one side of the pre-drilled hole and be clamped together with the insert on both sides of the wall containing the pre-drilled hole. This structure is simple, requiring no complex modifications to the battery pack structure to achieve a detachable connection between the testing part and the part to be tested. The installation process is also simple, simplifying the testing procedure.

[0022] Preferably, the end face of the fixing ring facing the card plate is further provided with an annular protrusion, the diameter of which is smaller than the diameter of the reserved hole.

[0023] In this design, the matching of the annular convex ring and the pre-drilled hole prevents the clamping plate from moving within the pre-drilled hole and prevents it from accidentally dislodging. Simultaneously, the matching of the convex ring and the pre-drilled hole further prevents misalignment of the fixed shaft, improving the reliability of the connection between the detection unit and the unit to be detected.

[0024] Preferably, the fixed shaft is perpendicularly connected to the card plate, and the axis of the fixed shaft is perpendicular to the limiting surface of the limiting part.

[0025] In this solution, by adopting the above structure, the limiting surface of the limiting part and the clamping plate can be arranged parallel to each other. When the insert is inserted into the reserved hole of the part to be tested, the clamping plate fits against the wall where the reserved hole is located, so that the limiting surface of the limiting part can be parallel to the wall where the reserved hole is located. Thus, the surface of the detection part that is limited by the limiting part can be parallel to the wall where the reserved hole is located, so that the detection port on the detection part can effectively fit against the detection port on the part to be tested. Furthermore, this structure is simple and easy to use.

[0026] Preferably, the fixing component further includes an operating lever connected to the limiting part for driving the limiting part to rotate.

[0027] In this solution, the operating lever allows for easy adjustment of the rotation of the limiting part, enabling the limiting part to restrict or release the detection part.

[0028] Preferably, the limiting part includes a limiting plate for abutting against the outer wall of the detection part.

[0029] In this solution, the limiting plate can abut against the outer wall of the detection unit on the side away from the detection unit, and can adapt to detection units with different structural forms.

[0030] Preferably, the limiting part includes a limiting groove for clamping the outer shell of the detection part.

[0031] In this solution, the limiting groove can clamp the outer shell of the detection unit, thereby restricting the bidirectional movement of the detection unit by the two groove walls, and improving the stability of the connection between the detection unit and the detected unit.

[0032] A detection assembly includes a detection section and a fixing component as described above. The detection assembly is used to detect electrical connectors on a battery pack. The detection section further includes a mounting plate and a terminal post assembly mounted on the mounting plate. The fixing component is provided on both sides of the mounting plate, and the limiting portions of the two fixing components are used to abut against the outer wall of the mounting plate.

[0033] In this solution, the mounting plate of the testing unit can be connected to the unit to be tested through the fixing components. Furthermore, fixing components are provided on both sides of the mounting plate, so that both ends of the testing unit can be connected to the battery pack. This allows the terminal assembly on the mounting plate to make uniform contact with the port of the electrical connector on the battery pack, and the port of the electrical connector on the battery pack can be transferred to the terminal assembly, facilitating the connection between the testing equipment and the terminal assembly for testing the battery pack.

[0034] Preferably, the detection unit and the electrical connector are connected by a positioning post and a positioning sleeve, and the limiting part abuts against the side of the mounting plate away from the electrical connector by a limiting plate, or the limiting part clamps both sides of the mounting plate by a limiting groove.

[0035] In this design, the positioning pin and positioning sleeve are connected to position the detection unit and the electrical connector, ensuring alignment between the detection unit and the connector's ports and improving the accuracy of electrical contact. Furthermore, the limiting part can abut against the mounting plate via a limiting plate or clamp the mounting plate via a limiting groove, restricting the position of the mounting plate and the electrode assembly mounted on it, thus ensuring reliable connection between the electrode assembly and the connector's ports.

[0036] Preferably, the battery pack further includes an outer casing with a pre-drilled hole for the insertion of the connector.

[0037] In this solution, by providing a pre-drilled hole on the outer casing, it is easy to insert the fixing component into the battery pack, so that the detection unit can be connected to the electrical connector also located on the outer casing.

[0038] Preferably, the detection unit further includes a wiring harness and a low-voltage connector located on the other side of the mounting plate.

[0039] In this design, one side of the mounting plate has a terminal post that contacts the port of the electrical connector, and the other side has a wiring harness connected to the terminal post and a low-voltage connector connected to the wiring harness. This allows the ports on the electrical connector of the battery pack to be converged on the low-voltage connector, facilitating connection to testing equipment and improving testing efficiency.

[0040] The positive advantages of this invention are as follows: the fixing component can be detachably connected to the part to be tested, thereby connecting the testing part to the part to be tested during testing. The connecting part is rotatably connected to the part to be tested, and the fixing component as a whole can rotate relative to the part to be tested. This allows the limiting part to rotate to a certain position and restrict the position of the testing part, preventing the testing part from detaching and ensuring a reliable connection between the testing part and the part to be tested. Therefore, for battery packs removed from electric vehicles, or individual battery packs, this fixing component can reliably and detachably connect the testing part to the electric vehicle, making testing flexible and convenient, simplifying the testing process, and facilitating on-site testing.

[0053] The components include: a fixing assembly 100, a connecting part 110, an insert 111, a retaining plate 112, a fixing shaft 113, a first elastic element 114, a movable part 115, a fixing ring 116, an annular protrusion 117, a limiting part 120, a limiting groove 121, a limiting plate 122, and an operating lever 130.

[0054] The components include: a detection unit 200, a mounting plate 210, a hole 211, a terminal assembly 220, a detection terminal 221, a high-voltage terminal 222, a low-voltage terminal 223, a mounting base 224, a second elastic element 225, a locking block 226, a positioning post 230, a wire harness 240, a low-voltage connector 250, and a mounting hole 260. Detailed Implementation

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] Example 1

[0057] like Figure 1 As shown, this embodiment of the invention provides a fixing component 100, which is used to detachably connect the detection unit 200 to the part to be detected. The fixing component 100 includes a connecting part 110 and a limiting part 120. The connecting part 110 is used to rotatably connect with the part to be detected. The limiting part 120 is connected to the detection unit 200. When the detection unit 200 is connected to the part to be detected, the limiting part 120 is used to restrict the detection unit 200 from detaching from the part to be detected.

[0058] The fixing component 100 can be detachably connected to the part to be tested, thereby connecting the testing part 200 to the part to be tested during testing. The connecting part 110 is rotatably connected to the part to be tested. The fixing component 100 as a whole can rotate relative to the part to be tested, so that the limiting part 120 can rotate to a certain position and restrict the position of the testing part 200, preventing the testing part 200 from detaching, so that the testing part 200 can be reliably connected to the part to be tested. Therefore, for battery pack 1 removed from electric vehicles, or individual battery pack 1, the fixing component 100 can reliably and detachably connect the testing part 200 to the electric vehicle, making testing flexible and convenient, the testing process simple, and easy to carry out on-site testing.

[0059] like Figure 13 The diagram shows a schematic of the structure when the fixing component 100 connects the detection unit 200 to the part to be tested. The part to be tested is the battery pack 1, and the detection unit 200 is a component that matches the battery terminal connector 11. It can contact the port on the battery terminal connector 11 and output the module information and charging and discharging performance of the battery pack to the testing equipment through a single plug-in interface, so as to facilitate the testing equipment to test the various performance of the battery pack 1.

[0060] In a specific implementation, the battery terminal connector 11 is disposed on the end wall 12 of the battery pack 1. One end of the connecting part 110 is inserted into the end wall 12 where the battery terminal connector is located, so that the fixing component 100 is connected to the battery pack 1 and arranged close to the battery terminal connector 11. Furthermore, the connecting part 110 can rotate relative to the end wall 12. During the rotation, the position of the limiting part 120 also changes accordingly. When rotated to a suitable position, it can limit the position of the detection part 200 relative to the end wall 12, so that the corresponding component on the detection part 200 can be reliably connected to the port of the battery terminal connector 11.

[0061] In a preferred embodiment, the connecting part 110 includes an insert 111 for inserting into the matching part on the part to be tested and for preventing the fixing component 100 from disengaging from the part to be tested.

[0062] like Figure 3 and Figure 4 As shown, one end of the connecting part 110 has an insert 111, such as Figure 10 As shown, the insert 111 can be inserted into the mating part on the end wall 12 where the battery terminal connector 11 is located, preventing the fixing component 100 from falling off the part to be tested, thereby avoiding loosening or misalignment of the connection between the detection part 200 and the battery pack 1, making the connection between the detection part 200 and the battery terminal connector 11 more reliable.

[0063] As a preferred implementation method, such as Figure 10 As shown, the mating part includes a reserved hole 13, such as Figure 3 and Figure 4 As shown, the insert 111 includes a retaining plate 112, at least a portion of which has an outer diameter larger than the inner diameter of the pre-drilled hole 13.

[0064] In specific implementation, a reserved hole 13 is provided on the end wall 12 where the battery terminal connector 11 is located. The retaining plate 112 can be tilted at a certain angle and inserted into the reserved hole 13 from the outside of the end wall 12. When the retaining plate 112 is fully inserted into the reserved hole 13, since at least part of the outer diameter of the retaining plate 112 is larger than the diameter of the reserved hole 13, it can be restricted to one side of the reserved hole 13, that is, restricted to the inside of the end wall 12. This allows the connecting part 110 and the part to be tested to be detachably connected, and this connection method is simple and easy to operate. Figure 10 As shown, at the location of the reserved hole 13 on the end wall 12 of the battery pack 1, the end wall 12 is provided with a protrusion 15, which can strengthen the structural strength at this location and also reserve a certain space on the inner side of the end wall 12 to accommodate the card plate 112.

[0065] like Figure 3 and Figure 4As shown, the clamping plate 112 is an oblong plate, with a length greater than the diameter of the reserved hole 13 and a width smaller than the diameter of the reserved hole 13. In other embodiments, the clamping plate 112 can also be other structural forms, such as an elliptical plate.

[0066] As a preferred implementation method, such as Figure 3 and Figure 4 As shown, the connecting part 110 also includes a fixed shaft 113, with the two ends of the fixed shaft 113 connected to the limiting part 120 and the insert 111, respectively. Thus, the fixed shaft 113 can connect the limiting part 120 and the insert 111, and also allows for a gap between the limiting part 120 and the insert 111 to reserve space for the arrangement of the detection part 200.

[0067] In specific implementation, such as Figure 5 As shown, one end of the fixed shaft 113 is connected to the center of the clamping plate 112. This end can be connected to the clamping plate 112 by an interference fit, or it can be an integrally formed component with the clamping plate 112. The other end of the fixed shaft 113 can be threaded to the limiting part 120, or it can be welded or connected by a shaft hole and a retaining ring.

[0068] As a preferred implementation method, such as Figure 3 and Figure 4 As shown, the connecting part 110 includes a first elastic member 114 and a movable member 115. The movable member 115 is axially movable along the fixed shaft 113. The first elastic member 114 is used to abut the movable member 115 against the part to be tested. The movable member 115 and the insert 111 are clamped on both sides of the reserved hole 13.

[0069] In specific implementation, when the insert 111 is inserted into the reserved hole, the movable member 115 moves away from the insert 111 along the axial direction of the fixed shaft 113 and compresses the first elastic member 114. After the insert 111 extends into the reserved hole 13, the first elastic member 114 recovers, and the movable member 115 can be pressed against the outer side of the end wall 12 of the battery pack 1 by the first elastic member 114. On the one hand, the fixed shaft 113 can be perpendicular to the outer side of the end wall 12 to be aligned. On the other hand, the movable member 115 can make effective surface contact with the outer side of the end wall 12 of the battery pack 1 and be clamped with the insert 111 on both sides of the end wall 12, so that the fixing assembly is stably connected to the part to be tested and the testing part 200 and the part to be tested are in an effective contact state.

[0070] As a preferred implementation method, such as Figure 3 and Figure 4As shown, the movable part 115 includes a retaining ring 116. The first elastic member 114 and the retaining ring 116 are both sleeved on the fixed shaft 113, and the retaining ring 116 is located between the insert 111 and the first elastic member 114. The outer diameter of the retaining ring 116 is larger than the diameter of the reserved hole 13.

[0071] In specific implementation, such as Figure 3 and Figure 5 As shown, the movable member 115 can be a retaining ring 116, with its central hole fitted onto the retaining shaft 113; the first elastic member 114 can be a spring, fitted onto the retaining shaft 113, with both ends of the spring able to contact the limiting part 120 and the retaining ring 116; and the retaining ring 116 is located between the insert 111 and the spring, so that when the fixing assembly 100 is connected to the battery pack 1, the first elastic member 114 can apply force to the retaining ring 116, and the outer diameter of the retaining ring 116 is larger than the diameter of the reserved hole 13, allowing the retaining ring 116 to abut against one side of the reserved hole 13 and be clamped together with the insert 111 on both sides of the wall where the reserved hole 13 is located. This structure is simple, requiring no complex modifications to the battery pack structure to achieve a detachable connection between the detection part and the part to be detected, and the installation process is relatively simple, simplifying the testing procedure.

[0072] And, such as Figure 11 As shown, during testing, the insert 111, movable member 115, and first elastic member 114 allow one end of the connecting portion 110 to be clamped in the reserved hole 13 of the end wall 12 where the battery connector 11 is located. The insert 111 and movable member 115 can contact the inner and outer surfaces of the end wall 12 respectively, allowing the fixed shaft 113 to automatically align itself relative to the end wall 12. Next, after the detection portion 200 is connected to the battery connector 11, the position of the detection portion 200 relative to the battery connector 11 is restricted by the rotation limiting portion 120, ensuring effective contact between the detection portion 200 and the battery connector 11. Furthermore, during the rotation of the limiting portion 120, because the insert 111 and movable member 115 are clamped in the end wall 12 where the battery connector 11 is located, the fixing assembly 100 as a whole will not tilt, thereby avoiding affecting the effective connection between the detection portion 200 and the battery connector 11.

[0073] As a preferred implementation method, such as Figure 3 and Figure 5 As shown, the end face of the fixing ring 116 facing the card plate 112 is also provided with an annular protrusion 117, the diameter of which is smaller than the diameter of the reserved hole 13.

[0074] In practical implementation, when the fixing ring 116 abuts against the outer side of the end wall 12 where the electrical connector of the battery pack 1 is located, the annular convex ring is located inside the reserved hole 13 and matches the reserved hole 13. This prevents the fixing component from shaking relative to the reserved hole, improves the stability of the connection between the fixing component and the part to be tested, and prevents the clamping plate 112 from accidentally disengaging from the reserved hole 13. At the same time, the matching of the annular convex ring and the reserved hole 13 can further prevent the fixing shaft 113 from deflecting, and improve the reliability of the connection between the detection part 200 and the part to be tested.

[0075] As a preferred implementation method, such as Figure 5 As shown, the fixed shaft 113 is perpendicularly connected to the clamping plate 112, and the axis of the fixed shaft 113 is perpendicular to the limiting surface of the limiting part 120.

[0076] In specific implementation, such as Figure 13 As shown, the limiting part 120 can be used to limit the position of the mounting plate 210 of the detection part 200. By adopting the above arrangement, the mounting plate 210 can be arranged parallel to the end wall 12 where the battery terminal connector 11 is located, so that the terminal assembly 220 provided on the mounting plate 210 can effectively fit with the port of the battery terminal connector 11. Moreover, this structure is simple and easy to use.

[0077] As a preferred implementation method, such as Figures 3-5 As shown, the fixing assembly 100 also includes an operating lever 130, which is connected to the limiting part 120 and is used to drive the limiting part 120 to rotate.

[0078] like Figure 5 As shown, one end of the limiting part 120 is a limiting end for limiting the detection part 200, and the operating lever 130 is provided on the limiting part 120 at the end opposite to the limiting end. Figure 12 As shown, interference between the operating lever 130 and the detection unit 200 can be avoided before adjusting the position of the limiting part 120. Furthermore, the operating lever 130 facilitates the adjustment of the rotation of the limiting part 120, allowing the limiting part 120 to restrict or release the detection unit 200.

[0079] As a preferred implementation method, such as Figure 3 and Figure 5 As shown, the limiting part 120 includes a limiting groove 121 for clamping the outer shell of the detection part 200.

[0080] like Figure 3 As shown, the limiting groove 121 is a groove that extends through one end of the limiting part 120 along the rotation direction of the limiting part 120. The limiting groove 121 can clamp one end of the outer shell of the detection part 200, such as... Figure 13As shown, the limiting groove 121 can clamp one end of the mounting plate 210 of the detection unit 200. The width of the limiting groove 121 matches the thickness of the mounting plate 210, so that the two groove walls of the limiting groove 121 can restrict the bidirectional movement of the detection unit 200 and improve the stability of the connection between the detection unit 200 and the detected unit 200.

[0081] Example 2

[0082] This embodiment provides another fixing component 100. The difference between the fixing component 100 in this embodiment and the fixing component 100 in embodiment 1 is that the structure of the limiting part 120 in the fixing component 100 of this embodiment is different from the structure of the limiting part 120 in embodiment 1. For example Figure 6 As shown, the limiting part 120 includes a limiting plate 122 for abutting against the outer wall of the detection part 200.

[0083] In a specific implementation, the surface of the limiting plate 122 facing the insert 111 can abut against the outer wall of the detection section 200 on the side away from the detection section 200, that is, it can abut against the mounting plate 210 of the detection section 200 on the side away from the battery pack 1, thereby adapting to detection sections 200 with different structural forms.

[0084] Example 3

[0085] This invention also provides a detection component 3, which includes a detection unit 200 and a fixing component 100 as described in Embodiments 1 and / or 2 above. The detection component 3 is used to detect the electrical connectors on the battery pack 1. Figure 7 As shown, a schematic diagram of the split structure of a detection component 3 is presented, wherein the detection component 3 includes the fixing component 100 as described in Embodiment 1 above.

[0086] like Figure 7 As shown, the detection unit 200 also includes a mounting plate 210 and an pole assembly 220 mounted on the mounting plate 210; both sides of the mounting plate 210 are provided with fixing components 100, and the limiting parts 120 of the two fixing components 100 are used to abut against the outer wall of the mounting plate 210.

[0087] In specific implementation, such as Figure 13 As shown, the mounting plate 210 of the detection unit 200 can be connected to the end wall 12 where the battery terminal connector 11 is located by the fixing component 100. Furthermore, fixing components 100 are provided on both sides of the mounting plate 210, so that both ends of the detection unit 200 can be connected to the end wall 12. Figure 10As shown, the battery terminal connector 11 is provided with multiple battery terminal posts 16, and the terminal post assembly 220 of the detection unit 200 has multiple detection terminals 221. The detection terminals 221 are matched with the battery terminal posts 16. By setting the fixing components 100 on both sides, each detection terminal post 221 can effectively contact the corresponding battery terminal post 16, so that the port of the electrical connector on the battery pack 1 can be transferred to the terminal post assembly 220, which facilitates the connection between the detection equipment and the terminal post assembly 220 for testing the battery pack 1.

[0088] In a preferred embodiment, the detection unit 200 and the electrical connector are connected by a positioning post 230 and a positioning sleeve 17. In a specific implementation, one of the positioning post 230 and the positioning sleeve 17 is disposed on the detection unit 200 and the other is disposed on the battery terminal electrical connector 11.

[0089] like Figure 8 As shown, the positioning post 230 is disposed on the detection unit 200, and the positioning sleeve 17 is disposed on the battery terminal connector 11. By fitting the positioning post 230 and the positioning sleeve 17 together, the detection terminal 221 on the detection unit 200 and the battery terminal 16 can be positioned, improving the accuracy of electrical contact. In addition, when the limiting part 120 rotates relative to the end wall 12 where the battery terminal connector 11 is located, the first elastic member 114 and the movable member 115 can correct the position of the fixed shaft 113. When the limiting part 120 is connected or in contact with the mounting plate 210, the first elastic member 114 and the movable member 115 can also adjust the position of the positioning post 230 to avoid uneven contact between the terminal assembly 220 and the battery terminal connector 11, thereby improving the reliability of the electrical connection.

[0090] In specific implementation, such as Figure 13 As shown, the limiting portion 120 clamps both sides of the mounting plate 210 via the limiting groove 121. In other embodiments, the limiting portion 120 abuts against the side of the mounting plate 210 away from the electrical connector via the limiting plate 122. Alternatively, one end of the mounting plate 210 is clamped by the limiting groove 121, and the other end abuts against the limiting plate 122.

[0091] In a preferred embodiment, the battery pack 1 also includes an outer casing 14, which has a reserved hole 13 for the insertion member 111 of the connecting part 110 to be inserted and connected.

[0092] In specific implementation, such as Figure 10 As shown, the battery terminal connector 11 is disposed on the end wall 12 of the outer casing 14. On both sides of the battery terminal connector 11, the end wall 12 is provided with reserved holes 13 for the insertion parts 111 of the two fixing components 100 to be inserted and connected respectively. The end wall 12 is provided with an elongated protrusion 15 at the position where the reserved hole 13 is provided.

[0093] As a preferred implementation method, such as Figure 7 and Figure 8 As shown, the testing unit 200 also includes a wiring harness 240 and a low-voltage connector 250 located on the other side of the mounting plate 210. One side of the mounting plate 210 has a terminal post that contacts the port of the electrical connector, and the other side has a wiring harness 240 connected to the terminal post and a low-voltage connector 250 connected to the wiring harness 240. This allows the terminals on the ports of the electrical connector of the battery pack 1 to be gathered on the low-voltage connector 250, facilitating connection to the testing equipment and improving testing efficiency.

[0094] like Figure 7 As shown, the mounting plate 210 has a flat structure with an elongated hole 211 in the middle for the wire harness 240 and the low-voltage connector 250 to pass through. Both the terminal assembly 220 and the mounting plate 210 have mounting holes 260. Fasteners pass through the mounting holes 260 of the terminal assembly 220 and the mounting plate 210 to connect the terminal assembly 220 and the mounting plate 210. Figure 9 As shown, the outer periphery of the pole assembly 220 is provided with a stepped portion, and the elongated hole matches the stepped portion.

[0095] like Figure 8 As shown, the battery terminal posts 16 on the terminal assembly 220 include high-voltage posts 222 and low-voltage posts 223. The low-voltage posts 223 are connected to the low-voltage connector 250 via a wiring harness 240. Corresponding high-voltage posts 222 are provided on both sides of the low-voltage posts 223. The mounting plate 210 also has through holes opposite to the high-voltage posts 222 to expose the end of the high-voltage posts 222 opposite to the battery terminal connector 11, thus enabling the high-voltage performance of the battery pack 1 to be tested by a testing device. Positioning posts 230 are located at both ends of the terminal assembly 220, and mounting holes 260 of the terminal assembly 220 are located on the upper and lower sides of the positioning posts 230.

[0096] like Figure 9 As shown, the terminal assembly 220 includes a low-voltage terminal 223 and a mounting base 224. The low-voltage terminal 223 passes through the mounting base 224 and is retractably connected to the mounting base 224. When the connecting part 110 is connected to the battery pack 1 and the limiting part 120 restricts the mounting plate 210, the low-voltage terminal 223 is compressed into the mounting base 224 by the port of the battery pack 1, thereby improving the stability and reliability of the electrical connection.

[0097] The mounting base 224 has a receiving cavity, and the low-voltage pole 223 is fitted with a second elastic member 225, which is located inside the receiving cavity. A locking block 226 is also engaged on the outer wall of the low-voltage pole 223, which is located inside the receiving cavity. The diameter of the locking block 226 is larger than the diameter of the second elastic member 225. The two ends of the second elastic member 225 are respectively connected to the side wall of the receiving cavity and the locking block 226.

[0098] When the detection component 3 is connected to the battery pack 1, the second elastic element 225 is compressed, allowing the low-voltage terminal 223 to fit against the detection terminal 221 (low voltage) of the battery terminal connector 11. The first elastic element 114 also allows the movable element 115 and the insert 111 to be clamped in the end wall 12 where the battery terminal connector 11 is located, making the compressed state of the second elastic element 225 more stable and the contact between the detection component 3 and the battery terminal connector 11 more reliable.

[0099] like Figure 10 , Figure 11 , Figure 12 and Figure 13 The steps for connecting the detection component 3 to the battery pack 1 are shown in the diagram. Figure 10 As shown, first connect the fixing assembly 100 to the end wall 12 where the battery terminal connector 11 is located. Specifically, move the movable member 115 to compress the first elastic member 114, insert the insert 111 obliquely into the reserved hole 13, and then release the movable member 115. The first elastic ring pushes the movable member 115 to straighten the fixing shaft 113. At the same time, the operating lever 130 on the fixing assembly 100 avoids the detection part 200, forming as shown in the figure. Figure 11 The state shown. (As indicated) Figure 12 As shown, the detection unit 200 is docked with the battery terminal connector 11. Specifically, the positioning post 230 on the detection unit 200 is first positioned with the positioning sleeve 17 of the battery terminal connector 11, and then the detection unit 200 is pushed further towards the battery terminal connector 11, so that the detection terminal post 221 on the detection unit 200 is compressed and aligns with the limiting part 120 of the fixing component 100. Figure 13 As shown, by rotating the limiting part 120 via the operating lever 130, the limiting grooves 121 at both ends respectively clamp the two ends of the mounting plate 210, or the limiting plate 122 abuts against the surface of the mounting plate 210 opposite to the battery terminal connector 11. Thus, the testing component 3 and the battery pack 1 are installed, and can be connected to the corresponding testing equipment via the connector to test the performance of the battery pack 1.

[0100] The above embodiments provide a specific implementation where the part to be detected is the battery pack 1. In other embodiments, the part to be detected may be other devices, and the corresponding detection part 200 may be connected to the part to be detected by the fixing component 100, and is not limited to the implementation provided in this embodiment.

[0101] In other embodiments, the fixing component can also be used for a detachable connection between two other components.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
