Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] like Figures 1 to 7As shown, this utility model embodiment provides a testing and analysis device for testing and analyzing battery cells or batteries. The testing and analysis device includes:

[0041] Test bench 1, with a positioning groove 11 on the top surface of test bench 1, the positioning groove 11 is used to fix the battery cell or battery.

[0042] Test board 2 is set on one side of positioning slot 11 and is electrically connected to the battery.

[0043] The probe holder 3 has a movable slot 12 on the side of the test stage 1. The probe holder 3 is movably connected in the movable slot 12 and is electrically connected to the battery cell.

[0044] In this embodiment of the invention, a positioning groove 11 is provided on the top surface of the test platform 1. The positioning groove 11 is used to fix the battery cell or battery. Therefore, the battery cell or battery can be installed through the positioning groove 11, and the positioning groove 11 can be used to position the battery cell or battery, preventing displacement during testing and analysis, and facilitating the installation and removal of the battery cell or battery. Furthermore, since the test plate 2 is located on one side of the positioning groove 11 and is electrically connected to the battery, and a movable groove 12 is provided on the side of the test platform 1, the probe holder 3 is slidably connected in the movable groove 12 and is electrically connected to the battery cell, the battery can be tested and analyzed through the test plate 2, and the battery cell can be tested and analyzed through the probe holder 3. In summary, the testing and analysis device provided by this embodiment of the invention can not only complete the testing and analysis of the battery, but also the testing and analysis of the battery cell, thereby reducing the manufacturing cost of the testing and analysis device and improving its utilization rate.

[0045] In the above embodiments, the test platform 1 can be a block structure, a frame structure, a box structure, or other structure with at least two intersecting surfaces. This embodiment of the present invention does not limit this type of structure. It should be noted that in this embodiment of the present invention, the top surface and the side surface of the test platform 1 are the two intersecting surfaces of the test platform 1, with the top surface being the surface where the top of the test platform 1 is located.

[0046] The positioning groove 11 on the top surface of the test platform 1 can be a recessed structure or a cavity structure formed by multiple protruding structures; this embodiment of the present invention does not limit this. For example, taking a positioning groove 11 formed by multiple protruding structures as an example, the top surface of the test platform 1 can have multiple ribs forming a positioning cavity structure. This positioning cavity structure can be a non-closed cavity structure to facilitate the installation of battery cells or batteries within it. The positioning cavity structure formed by the positioning groove 11 can be determined based on the structure of the battery and the battery cell; this embodiment of the present invention does not limit this. Thus, the positioning groove 11 can be used to install batteries or battery cells, and after installation, the positioning groove 11 ensures the stability of the installation, preventing displacement, and also facilitates the removal and installation of battery cells or batteries from the positioning groove 11.

[0047] Test board 2 is a motherboard device that performs battery charging and discharging, functional testing, or manual analysis. Typically, test board 2 can have multiple test pins, including positive terminal test pins, negative terminal test pins, clock line test pins, and data line test pins. Test board 2 is located on one side of the positioning slot 11 for easy electrical connection with the battery installed in the positioning slot 11. It should be noted that the positioning slot 11 has a notch on the side near test board 2, through which the battery connector can be led out.

[0048] In addition, the probe holder 3 is the main component that makes electrical connections with the battery cell. The probe holder 3 can be movably connected to the side of the test bench 1 by means of sliding connection, snap-fit, etc., and has a movable slot 12 opened in it to meet the testing and analysis needs of the battery cell.

[0049] In some embodiments, the probe holder 3 includes: a mounting base 31, a first probe 32 and a second probe 33. The mounting base 31 is slidably connected in the movable groove 12. The first probe 32 and the second probe 33 are mounted on the mounting base 31. The battery cell includes a positive electrode and a negative electrode. The first probe 32 is connected to the positive electrode and the second probe 33 is connected to the negative electrode.

[0050] In this embodiment, the mounting base 31 is a block-shaped structure, frame-shaped structure, or other structure with a mounting surface. The first probe 32 and the second probe 33 can be mounted on the side surface of the mounting base 31 facing the test stage 1 by means of plugging, sliding connection, or threaded connection. In this way, by connecting the first probe 32 to the positive electrode and the second probe 33 to the negative electrode, the probe holder 3 can be made in close contact with the positive and negative electrodes of the battery cell. It should be noted that the mounting base 31 can be connected to the movable groove 12 by setting a slider or slide rail, or by setting a sliding rod or sliding through hole to achieve a sliding connection between the mounting base 31 and the movable groove 12. For example, taking the mounting base 31 connected to the movable groove 12 by setting a slider or slide rail as an example, a slide rail can be set on the bottom of the movable groove 12, and a sliding protrusion can be set on the bottom of the mounting base 31, so that the sliding protrusion is slidably connected in the slide rail. Taking the sliding connection between the mounting base 31 and the movable groove 12 achieved by setting a sliding rod and a sliding through hole as an example, a sliding rod can be set on the side wall of the movable groove 12 facing the mounting base 31, and a sliding hole is provided on the mounting base 31. The sliding rod and the sliding hole are fitted with a clearance, so that the mounting base 31 can slide along the extension direction of the sliding rod under the guidance of the sliding rod. In this way, since the mounting base 31 is slidably connected in the movable groove 12, it is not only convenient to replace different probe holders 3, but also ensures the stability of the connection between the first probe 32 and the positive electrode, and the stability of the connection between the second probe 33 and the negative electrode as the mounting base 31 slides.

[0051] In some embodiments, the distance between the first probe 32 and the second probe 33 in a first direction is adjustable, wherein the first direction is the direction that intersects with the axial direction of the first probe 32.

[0052] In this embodiment, since the distance between the first probe 32 and the second probe 33 in the first direction is adjustable, when the distance between the positive and negative electrodes of the battery cell changes in the first direction, that is, when the probe holder 3 needs to be used with different types of battery cells, it is only necessary to adjust the distance between the first probe 32 and the second probe 33 in the first direction to meet the testing and analysis requirements of different types of battery cells, so that there is no need to replace the matching probe holder 3, thereby saving the manufacturing cost of the testing and analysis device.

[0053] In some embodiments, the probe holder 3 is provided with a sliding through groove 311, and one end of the first probe 32 away from the first groove wall 121 of the movable groove 12 is slidably connected in the sliding through groove 311, and one end of the second probe 33 away from the first groove wall 121 of the movable groove 12 is slidably connected in the sliding through groove 311, wherein the first groove wall 121 is the groove wall in the movable groove 12 that intersects the axial direction of the first probe 32.

[0054] In this embodiment, since the probe holder 3 has a sliding groove 311, the end of the first probe 32 away from the first groove wall 121 of the movable groove 12 is slidably connected in the sliding groove 311, and the end of the second probe 33 away from the first groove wall 121 of the movable groove 12 is slidably connected in the sliding groove 311. Therefore, the distance between the first probe 32 and the second probe 33 in the first direction can be changed by sliding the first probe 32 and the second probe 33 in the sliding groove 311 to meet the above requirements for adapting to different types of battery cells.

[0055] It should be noted that the first probe 32 may include a bent first needle portion 321 and a first connecting portion 322, and the second probe 33 may include a bent second needle portion 331 and a second connecting portion 332. The sliding groove 311 includes a first groove 3111 and a second groove 3112. The second groove 3112 extends through the first needle portion 321 along its extension direction, and the first groove 3111 extends through the first needle portion 321 along its extension direction. The first needle portion 321 and the second needle portion 331 are slidably connected in the second groove 3112, and the first connecting portion 321 and the second connecting portion 332 are slidably connected in the first groove 3111. Thus, since the penetrating directions of the first through groove 3111 and the second through groove 3112 are different, and the first needle portion 321 and the first connecting portion 321 are bent, and the second needle portion 331 and the second connecting portion 332 are bent, after the first needle portion 321 and the second needle portion 331 are slidably connected in the second through groove 3112, and the first connecting portion 321 and the second connecting portion 332 are slidably connected in the first through groove 3111, the first probe 32 and the second probe 33 can slide in the sliding through groove 311, and the first probe 32 and the second probe 33 can be limited and installed through the sliding through groove 311.

[0056] In some embodiments, a magnetic suction element is provided on the first groove wall 121, and the probe seat 3 is magnetically connected to the magnetic suction element.

[0057] In this embodiment, since a magnetic suction element is provided on the first groove wall 121, and the probe seat 3 is magnetically connected to the magnetic suction element, the stability of the connection between the first probe 32 and the positive electrode and the stability of the connection between the second probe 33 and the negative electrode can be further guaranteed.

[0058] In some embodiments, the test analysis apparatus further includes a control component 4 and a guide plate 5. The control component 4 is installed in the test bench 1 and connected to the guide plate 5. The control component 4 controls the guide plate 5 to move toward or away from the top surface of the test bench 1. The guide plate 5 includes a guide groove 51, and the battery includes a connector. The connector is fastened to the test plate 2 through the guide groove 51. When the control component 4 controls the guide plate 5 to move away from the top surface of the test bench 1, the connector and the test plate 2 separate.

[0059] In this embodiment, since the test analysis device also includes a control component 4 and a guide plate 5, and the control component 4 is installed in the test bench 1 and connected to the guide plate 5, the control component 4 can control the guide plate 5 to move towards or away from the top surface of the test bench 1. Furthermore, since the guide plate 5 includes a guide groove 51, and the battery includes a connector, which is fastened to the test plate 2 via the guide groove 51, when the control component 4 controls the guide plate 5 to move away from the top surface of the test bench 1, the connector and the test plate 2 separate. Therefore, the control component 4 can control the separation of the connector and the test plate 2, avoiding damage to the connector during separation and facilitating separation. It should be noted that the guide groove 51 of the guide plate 5 can extend along the positioning groove 11 towards the test plate 2, thereby positioning and guiding the connector while ensuring contact between the connector and the test plate 2. In addition, a snap-fit ​​hole can be opened at the bottom of the guide groove 51, through which the connector contacts can pass and make contact with the test pins on the test board 2, thereby ensuring the tightness of the connection between the connector and the test board.

[0060] It should also be noted that the control component 4 can be a cylinder push rod structure, a mechanical linkage structure, or other control components that can drive the guide plate 5 to move toward or away from the top surface of the test bench 1. This embodiment of the utility model does not limit this.

[0061] In some embodiments, the control assembly 4 includes a push rod 41, a drive link 42, and a drive bracket 43. One end of the drive link 42 is connected to the first end of the push rod 41, the other end of the drive link 42 is connected to the third end of the drive bracket 43, the fourth end of the drive bracket 43 is connected to the guide plate 5, and the second end of the push rod 41 extends out of the top surface of the test bench 1 and is movably connected in the test bench 1. The first and second ends are two opposite ends of the push rod 41 in a second direction, and the third and fourth ends are two opposite ends of the drive bracket 43 in a second direction, which intersects with the plane containing the top surface of the test bench 1.

[0062] In this embodiment, when the first end of the push rod 41 is pressed, the second end of the push rod 41 drives the drive linkage 42 to move the third end of the drive bracket 43. As the third end of the drive bracket 43 moves, the fourth end of the drive bracket 43 drives the guide plate 5 to move away from the top surface of the test platform 1, thereby separating the connector and the test plate 2. It should be noted that a through hole can be opened on the test platform 1 so that the push rod 41 is embedded in the through hole, and the push rod 41 and the through hole are in clearance fit. At the same time, the first end of the push rod 41 needs to extend out of the top surface of the test platform 1 so as to provide sufficient pressing area through the first end of the push rod 41.

[0063] In some embodiments, the drive link 42 includes a bent rod 421 and a base 422. The bent portion of the bent rod 421 is hinged to the base 422. One end of the bent rod 421 is connected to the first end of the top rod 41, and the other end of the bent rod 421 is connected to the third end of the drive bracket 43. When the top rod 41 moves in the second direction toward the base 422, the bent rod 421 drives the drive bracket 43 to move in the second direction away from the base 422.

[0064] In this embodiment, when the first end of the push rod 41 is pressed, one end of the bent rod 421 moves away from the top surface of the test bench 1. Since the bent part of the bent rod 421 is hinged to the base 422, the other end of the bent rod 421 moves towards the top surface of the test bench 1, thereby driving the drive bracket 43 to move towards the top surface of the test bench 1. Finally, driven by the drive bracket 43, the guide plate 5 moves away from the top surface of the test bench 1. In this way, during the entire driving process, only the push rod 41 needs to be pressed to separate the connector and the test plate 2, making the whole process time-saving and labor-saving.

[0065] It should be noted that the drive bracket 43 can be a block structure with a through groove at the bottom, allowing one end of the bent rod 421 to be fixed in the through groove, thus enabling the end of the bent rod 421 to drive the drive bracket 43 to move. The guide plate 5 can include a mounting part and a guide part. One end of the mounting part is connected to the top of the drive bracket 43, and the other end of the mounting part is connected to the guide part. A guide groove 51 is provided on the guide part, which is located on the top wall of the test bench 1. This facilitates control of the distance between the guide part and the top wall of the guide plate 5. Furthermore, it should be noted that an elastic element can also be provided on the drive bracket 43. One end of the elastic element can be fixed to the drive bracket 43, and the other end of the elastic element abuts against the inner wall of the test bench 1. In this way, when the drive bracket 43 moves towards the top surface of the test bench 1, the elastic element can be compressed. When the force applied to the push rod 41 is removed, the push rod 41 can return to its initial state under the action of the restoring force of the elastic element.

[0066] In some embodiments, the bottom of the positioning groove 11 is provided with a barcode scanning through hole 111, which is disposed through the top and bottom surfaces of the test platform 1 along a second direction, wherein the second direction intersects with the plane containing the top surface of the test platform 1.

[0067] In this embodiment, since the barcode scanning hole 111 is disposed through the top and bottom surfaces of the test platform 1 along the second direction, the QR code on the bottom of the cell or the QR code on the bottom of the battery can be directly facing the barcode scanning hole 111, which facilitates barcode scanning testing and analysis of the battery or cell through the barcode scanning hole 111.

[0068] In some embodiments, the number of positioning slots 11 and movable slots 12 provided on the test bench 1 are both multiple, and the multiple positioning slots 11 are arranged along the first direction, the multiple movable slots 12 are arranged along the first direction, the number of test plates 2 is equal to the number of positioning slots 11, and the number of probe seats 3 is equal to the number of movable slots 12, wherein the first direction is consistent with the extension direction of the long side of the top surface of the test bench 1.

[0069] In this embodiment, since the test bench 1 is provided with multiple positioning slots 11 and multiple movable slots 12, and the multiple positioning slots 11 are arranged along the first direction, the multiple movable slots 12 are arranged along the first direction, the number of test plates 2 is equal to the number of positioning slots 11, and the number of probe holders 3 is equal to the number of movable slots 12, multiple batteries or multiple cells can be tested and analyzed simultaneously by the test and analysis device provided by this utility model embodiment. This not only improves the testing and analysis efficiency of batteries and cells, but also saves the manufacturing cost of the test and analysis device.

[0070] It should be noted that, in the embodiments of this utility model, the first direction is as follows: Figure 1 The direction shown by X in the middle, the second direction is as follows Figure 1 The direction shown in the middle Z, the axial direction of the first probe 32 is as follows Figure 1 The direction indicated by Y in .

[0071] As can be seen from the above embodiments, in this embodiment of the present invention, since a positioning groove 11 is provided on the top surface of the test platform 1, the positioning groove 11 is used to fix the battery cell or battery. Therefore, the battery cell or battery can be installed through the positioning groove 11, and the positioning groove 11 can be used to position the battery cell or battery, preventing the battery cell or battery from shifting during testing and analysis, and facilitating the installation and removal of the battery cell or battery. Furthermore, since the test plate 2 is located on one side of the positioning groove 11 and is electrically connected to the battery, and a movable groove 12 is provided on the side of the test platform 1, the probe holder 3 is slidably connected in the movable groove 12 and is electrically connected to the battery cell, the battery can be tested and analyzed through the test plate 2, and the battery cell can be tested and analyzed through the probe holder 3. In summary, the test and analysis device provided by this embodiment of the present invention can not only complete the testing and analysis of the battery through the same test and analysis device, but also complete the testing and analysis of the battery cell through the same test and analysis device, thereby reducing the manufacturing cost of the test and analysis device and improving the utilization rate of the test and analysis device.
