[0042] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application are further described in detail below in combination with the drawings and embodiments, and the described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0043] In the following description, "some embodiments" are related to a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0044] The terms "first / second / third" involved are only to distinguish similar objects, and do not represent a specific order of the objects, and it can be understood that "first / second / third" can be interchanged with a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the present application and are not intended to limit the present application.

[0046] At present, new energy is more and more widely used in life and industry. New energy is not only applied to energy storage power supply systems such as hydroelectric, thermal, wind and solar power stations, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also increasing.

[0047] In the embodiments of the present application, the battery that needs to be electrically tested may be a battery cell. A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy, and can be used to make a battery module or battery pack, thereby being used to supply power to an electrical device. The battery cell may be a secondary battery, which refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and continue to be used. The battery cell may be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, etc., and the embodiments of the present application do not limit this.

[0048] In the embodiment of the present application, the battery that needs to be electrically tested can also be a single physical module including one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel, or in hybrid through a bus assembly.

[0049] In the embodiment of the present application, the energy storage module may also need to be electrically inspected. The energy storage module is commonly used in scenarios such as energy storage in power systems, grid connection of renewable energy, and zero-carbon smart parks. In these scenarios, the structure of the energy storage module is relatively complex, and some may be installed at high places. At this time, technicians use handheld testing equipment to perform electrical inspections, which requires multiple people to collaborate on the inspection, and has poor operability.

[0050] In related technologies, the grounding resistance between different locations on the same plane can be measured by one tester. If the locations are on different planes and there is a height difference, one tester cannot perform the measurement. The collaboration of multiple people increases the cost and is inefficient. At the same time, multiple people operate in a complex environment (such as at high places or in a narrow space), which poses a greater safety risk.

[0051] In order to solve the problem in related technologies that it is difficult to conduct electrical testing in a complex environment, the applicant believes that a fixing device for the testing equipment can be provided, including a longitudinal beam, a transverse beam and a transverse beam limiter. The longitudinal beam is provided with a transverse beam mounting through-hole passing through the longitudinal beam, and the transverse beam is provided with a connecting piece. The testing equipment is detachably fixed to the fixing device through the connecting piece. The transverse beam limiter fixes the relative position between the transverse beam and the longitudinal beam when the transverse beam passes through the transverse beam mounting through-hole, and the fixing device is fixed to the equipment to be tested through the longitudinal beam or transverse beam on the fixing device.

[0052] First, the embodiment of the present application can detachably fix the detection equipment on the fixing device, and the fixing device can be fixed on the device to be tested. There is no need to hold the detection equipment when performing electrical testing, which frees the hands of the technician, improves the safety of the technician when performing electrical testing, and improves the detection efficiency; secondly, the fixing device can replace the detection equipment, so that the embodiment of the present application can be applied in various scenarios, expanding the use scenarios of the fixing device; finally, the fixing device can be fixed on the surface of the device to be tested, so that the tester can focus on the testing process and improve the accuracy of the test results.

[0053] Figure 1 This is a schematic diagram of the structure of the fixing device of the detection equipment provided in the embodiment of the present application. Figure 1 ,like Figure 1 As shown, the fixing device includes a longitudinal beam 101, a transverse beam 102 and a transverse beam stopper 103. The longitudinal beam 101 is provided with a transverse beam mounting through hole 104 that passes through the longitudinal beam 101, and the transverse beam 102 is provided with a connecting piece 105. The detection device is detachably fixed to the fixing device through the connecting piece 105. When the transverse beam 102 passes through the transverse beam mounting through hole 104 on the longitudinal beam 101, the transverse beam stopper 103 abuts against the side wall of the transverse beam 102 (for example, Figure 1 As shown, the crossbeam limiter 103 passes through part of the longitudinal beam 101 and rests against the side wall of the crossbeam 102, or any other feasible method can be used) to fix the relative position between the crossbeam 102 and the longitudinal beam 101, so that the crossbeam 102 will not move in the crossbeam mounting hole 104, thereby reducing the shaking of the detection equipment installed on the fixing device and improving the safety of the detection equipment.

[0054] In the embodiment of the present application, at least one of the crossbeam 102 and the longitudinal beam 101 can be fixed to the device under test. For example, a fixing device can be fixed to the device under test using a suction cup provided on the crossbeam or the longitudinal beam. This eliminates the need for the tester to hold the test device in their hands, allowing them to focus on the test process, thereby improving the accuracy of the test results.

[0055] Figure 2 The figure shows a case where the fixing device includes a cross beam 102 and a longitudinal beam 101. The fixing device can also include two cross beams 102 and two longitudinal beams 101, or can be composed of a larger number of cross beams and longitudinal beams. As long as the fixing effect can be achieved, this application does not limit the number of cross beams and longitudinal beams.

[0056] Here, when the fixture is applied to the battery field, the detection equipment can be a resistance tester, micro-ohmmeter, multimeter, grounding tester, switch characteristic tester, charge and discharge tester and other instruments used for electrical testing; when the fixture is applied to other fields, the detection equipment can be a water level meter, digital ultrasonic flaw detector and other detection instruments related to various fields.

[0057] In some embodiments, when the fixture is applied to the battery field, the device to be tested may be battery equipment such as an electrical cabinet, a battery module, an energy storage module, and a centralized grid-connected energy storage system; when the fixture is applied to other fields, the device to be tested may be a structure such as a wall, a bridge, or a utility pole.

[0058] The crossbeam stopper 103 may be any structure such as a screw, a buckle, a latch, etc. that can fix the relative position between the crossbeam 102 and the longitudinal beam 101 .

[0059] In an embodiment of the present application, the connecting member 105 can be a fixed hook, which is wrapped with an elastic band (such as a rubber band) to fix the detection equipment on the fixing device; it can also be a magnetic bracket, which uses magnetic force to fix various measuring instruments such as resistance testers and test meters.

[0060] Figure 2 This is a schematic diagram of the structure of the fixing device of the detection equipment provided in the embodiment of the present application. Figure 1 ,like Figure 2 As shown, the number of longitudinal beams 101 is 2, and the number of cross beams 102 can be multiple (such as Figure 3 2 shown in ).

[0061] Each longitudinal beam 101 can be provided with a plurality of cross-beam mounting holes 104, the axial direction of the cross-beam mounting holes 104 being parallel to the first direction A, and the axes of the plurality of cross-beam mounting holes 104 on one longitudinal beam 101 being collinear with the axes of the plurality of cross-beam mounting holes 104 on another longitudinal beam 101, so that the cross-beam 102 passing through the corresponding longitudinal beam 101 can be parallel to the first direction A.

[0062] The plurality of cross beams 102 may be disposed one by one through the cross beam mounting through holes 104 with corresponding collinear axes on the two longitudinal beams 101 .

[0063] In the embodiment of the present application, there may be multiple crossbeam mounting through holes 104 on the longitudinal beam 101, and the number of crossbeams 102 may also be multiple, so as to achieve fixation without the use of size detection equipment.

[0064] In the embodiment of the present application, the length of the crossbeam is adjustable through multiple crossbeams and two longitudinal beams, and different test instruments and equipment can be installed to meet different test requirements.

[0065] Figure 3 This is a schematic diagram of the partial structure of the connection between the crossbeam and the longitudinal beam provided in the embodiment of the present application. Figure 3As shown, the crossbeam 102 is provided with a plurality of first fixing holes 301 distributed along the length direction of the crossbeam 102, and the longitudinal beam 101 is provided with second fixing holes 302. The size of the second fixing holes 302 is the same as that of the first fixing holes 301. The second fixing holes 302 are adapted to the first fixing holes 301 to adjust the change in the length of the crossbeam 102.

[0066] In some embodiments, when the beam stopper 103 passes through the second fixing hole 302 and any first fixing hole 301 of the plurality of first fixing holes, the beam stopper 103 can abut against the inner wall of the beam mounting through hole 104, such as Figure 1 shown.

[0067] The crossbeam limiter 103 is also used to pass through the first fixing hole 301 and the second fixing hole 302 when the crossbeam 102 passes through the crossbeam mounting hole 104 and the second fixing hole 302 is aligned with any first fixing hole of the multiple first fixing holes, so as to fix the relative position between the crossbeam 102 and the longitudinal beam 101, so that the crossbeam 102 will not move in the crossbeam mounting hole 104, thereby reducing the shaking of the detection equipment installed on the fixing device and improving the safety of the detection equipment.

[0068] In some embodiments, the second fixing hole 302 may or may not pass through the longitudinal beam 101. In the case where the cross beam and the longitudinal beam can be fixed, the second fixing hole 302 may also not pass through the longitudinal beam 101, such as Figure 3 shown.

[0069] Here, when the second fixing hole 302 passes through the longitudinal beam 101 , the axial direction of the second fixing hole 302 is perpendicular to the axial direction of the cross beam mounting through hole 104 .

[0070] Here, the inner walls of the first fixing hole 301 and the second fixing hole 302 may have threads, and the crossbeam limiting member 103 is correspondingly a screw, so as to make the connection between the crossbeam and the longitudinal beam more secure.

[0071] In the embodiment of the present application, in order to adapt the fixing device to different detection equipment, such as Figure 4 As shown, a plurality of first fixing holes 301 are provided along the length direction of the crossbeam 102 , and the longitudinal beam 101 changes the length of the fixing device in the transverse direction by connecting different first fixing holes 301 .

[0072] In the embodiment of the present application, the second fixing holes of the longitudinal beam are matched with the multiple first fixing holes on the crossbeam, thereby achieving adjustable lateral length of the fixing device, allowing the fixing device to adapt to different detection equipment and broadening the scope of application of the fixing device.

[0073] In some embodiments, the fixing device may further include a fixing structure, which may be provided at both ends of the crossbeam or the longitudinal beam to fix the fixing device on the device to be tested. Figure 4 is a schematic diagram of a partial structure of a fixed structure provided in an embodiment of the present application, Figure 4 Figure a is a front view of the fixed structure, and Figure b is a side view of the fixed device. Figure 5 As shown, the fixing structure can be provided at both ends of the longitudinal beam 101, and the fixing structure can include a suction cup 401 and a suction cup button 402. The suction cup 401 can be provided at both ends of the longitudinal beam 101, and the suction cup button 402 is connected to the suction cup 401, and is used to achieve the suction and release operation of the suction cup 401 on the device under test by pressing or rotating.

[0074] The suction cup works by leveraging atmospheric pressure. When the cup is squeezed, the air inside is expelled, causing the pressure inside the cup to drop below the outside atmospheric pressure. This pressure difference causes the outside atmospheric pressure to press the cup tightly against the device under test, creating a strong friction between the cup and the device under test, ensuring stable suction.

[0075] In some embodiments, to ensure the adsorption effect, the adsorption location can be cleaned and the suction cup can be softened before use.

[0076] In the embodiment of the present application, pressing the suction cup button 402 can perform the adsorption action, so that the suction cup 401 generates a vacuum and is adsorbed on the device to be tested. When the test is completed or the test location needs to be changed, pressing the suction cup button 402 again can release the vacuum and separate the suction cup 401 from the device to be tested.

[0077] In the embodiment of the present application, the suction force of a single suction cup 401 can be greater than 50 kilograms (kg), and four suction cups can firmly fix the fixing device on the surface of components such as an electrical cabinet, thereby improving the safety of the detection equipment.

[0078] In the embodiment of the present application, the fixing structure may be any structure that can fix the fixing device on the device under test.

[0079] In an embodiment of the present application, during testing, the fixing device can be fixed to the surface of the device to be tested by a suction cup, so that the tester can focus on the testing process and improve the accuracy of the test results.

[0080] Figure 5 : is a structural diagram of the test line adapter hole on the fixing device provided in an embodiment of the present application, such as Figure 5As shown, the fixture also includes a test line adapter hole 501, which can be provided on the longitudinal beam 101. The test line adapter hole 501 is used to connect the test line and extension line of the detection equipment respectively. The other end of the extension line is connected to the test part of the device under test. The extension line is used to expand the detection range of the detection equipment. Here, the test line adapter hole 501 can also be provided on the crossbeam 102.

[0081] In an embodiment of the present application, after the detection device is fixed to the fixture, it can be tested through the test line of the detection device, such as performing a clamped ground resistance test on the energy storage module. However, when the energy storage module is large and there are many test points, frequently changing the position of the fixture will reduce the detection efficiency. Therefore, in an embodiment of the present application, the test line of the detection device can be inserted into one end of the test line adapter hole 501 provided in the embodiment of the present application, and the other end is connected to an extension line. The length of the extension line is not limited in the embodiment of the present application. This can expand the detection range of the detection device. In scenarios with many test points, there is no need to frequently change the position of the fixture, thereby improving the detection efficiency.

[0082] The test line adapter hole and extension line provided in the embodiment of the present application can expand the detection range of the detection equipment. In scenarios with a large number of detection points, there is no need to frequently change the position of the fixing device, thereby improving the detection efficiency.

[0083] In the embodiment of the present application, the fixing device may include a plurality of test line adapter holes 501, such as Figure 6 As shown, the fixing device may include four test line adapter holes 501, but the embodiment of the present application does not limit the number of test line adapter holes, which can be set according to the requirements of the detection equipment.

[0084] Figure 6 FIG. 1 is a partial structural diagram of a test line adapter hole provided in an embodiment of the present application. Figure 7 As shown, the test line adapter hole includes a first adapter hole 601 and a second adapter hole 602. The first adapter hole 601 and the second adapter hole 602 are connected by an adapter line 603, and the adapter line 603 is located inside the longitudinal beam 101. The first adapter hole 601 and the second adapter hole 602 can be a multimeter test line interface, which can be connected to the detection interface of any detection equipment.

[0085] In an embodiment of the present application, when the detection device is a digital microohmmeter, the test holes of the digital microohmmeter are connected through four test line adapter holes, which effectively eliminates the influence of contact resistance and lead resistance on the measurement results, thereby accurately measuring low resistance and reducing measurement errors.

[0086] In an embodiment of the present application, the first adapter hole 601 and the second adapter hole 602 can adopt specifications consistent with the detection equipment, such as using a standard multimeter test line interface, so that the test line adapter hole can match most detection equipment and improve the usage scenario of the fixing device.

[0087] Here, the extension cord can use any multimeter test lead, and can be freely switched between probes, hooks, and alligator clips to match different detection needs.

[0088] In some embodiments, the electrical strength of the adapter cable 603 is 1000V CAT II (indicating that it can be safely used under an AC voltage of up to 1000V) and 600V CAT III (indicating that it is suitable for voltage environments up to 600V and can withstand transient voltage shocks), which can ensure the safety of testers during high-voltage testing and improve safety of use.

[0089] The test line adapter hole of the embodiment of the present application adopts a standard multimeter test line interface, which can match most detection equipment and improve the usage scenarios of the fixing device; at the same time, the adapter wire inside the test line adapter hole can withstand transient voltage shocks under high voltage, which can ensure the safety of testers during high-voltage testing and improve the safety of the fixing device.

[0090] In some embodiments, in order to make the fixture meet different usage scenarios, the fixture can be folded by adjusting the longitudinal beams to meet the needs of testing small-sized specimens or confined space environments.

[0091] Figure 1 This is a schematic diagram of the structure of the fixing device provided in the embodiment of the present application. Figure 7 ,like Figure 7 As shown, the longitudinal beam 101 may include a first adjustable longitudinal beam 701 and a second adjustable longitudinal beam 702, and the fixing device further includes a longitudinal beam stopper 703. The first adjustable longitudinal beam 701 is provided with a first adjustment through hole ( Figure 7 The second adjustable longitudinal beam 702 is provided with a second adjustment through hole ( Figure 7 (not shown), the first adjustable longitudinal beam 701 and the second adjustable longitudinal beam 702 are fixed by a longitudinal beam stopper 703 that passes through the first and second adjustment holes. When the longitudinal beam stopper 703 passes through the first and second adjustment holes, the first and second adjustable longitudinal beams 701 and 702 are relatively fixed, thereby fixing the longitudinal beam lengths and the angle between the first and second adjustable longitudinal beams 701 and 702.

[0092] like Figure 7 As shown, the first adjustable longitudinal beam 701 and the second adjustable longitudinal beam 702 can be rotated by the longitudinal beam limiter 703, as shown in FIG. Figure 8In the embodiment of the present application, the angle between the first adjustable longitudinal beam 701 and the second adjustable longitudinal beam 702 can be between 0 and 180 degrees to adapt to different detection environments.

[0093] In some embodiments, the inner walls of the first adjustment through hole and the second adjustment through hole may have threads, and the longitudinal beam stopper 703 may be a screw to fix the first adjustable longitudinal beam 701 and the second adjustable longitudinal beam 702 .

[0094] In the embodiment of the present application, the fixing device is folded by the first adjustable longitudinal beam and the second adjustable longitudinal beam, so that the fixing device can meet the testing requirements of small-sized specimens or narrow space environments, thereby improving the applicability of the fixing device.

[0095] Figure 2 This is a schematic diagram of the structure of the fixing device provided in the embodiment of the present application. Figure 8 ,like Figure 9 As shown, the size of the first adjustment hole 801 and the second adjustment hole 802 in the longitudinal beam extension direction a is larger than the size perpendicular to the extension direction b. The length of the longitudinal beam of the fixing device can be adjusted by the adjustable holes in the longitudinal beam extension direction.

The detection device can be fixed on the fixed longitudinal beam 1001 by connecting the first fixing component 1002 and the second fixing component.

[0101] Here, the first fixing component 1002 can be set according to needs. The first fixing component 1002 can be a mounting hole, and the second fixing component can be a buckle corresponding to the mounting hole; the first fixing component 1002 can also be a screw hole, and the second fixing component can be a screw corresponding to the screw hole. The first fixing component 1002 and the second fixing component are components that can be connected, and the embodiment of the present application does not limit the specific structure. Figure 11 4 first fixing components 1002 are shown as examples, which can fix the milliohm test meter, such as Figure 11 As shown, Figure 12 This is a structural diagram of a fixing device provided in an embodiment of the present application in combination with a milliohm test meter, wherein a milliohm test meter 1101 is mounted on a fixed longitudinal beam 1001 .

[0102] In some embodiments, when the first fixing component 1002 is a screw hole, the matching screw can be a 1 / 4 inch screw. At this time, the fixed longitudinal beam 1001 can be installed with an infrared thermal imager based on the first fixing component 1002, and the fixing device can be transformed into an infrared thermal imager stabilizer to improve the shooting quality of the infrared thermal imager.

[0103] In an embodiment of the present application, a detection device with higher stability requirements can be connected through a fixed longitudinal beam connected to the cross beam, and the stability of the detection device can be achieved through the first fixing component, so that the fixing device can be applied to more usage scenarios.

[0104] ​ This is a structural diagram of a fixing device provided in an embodiment of the present application in combination with a micro-ohmmeter. The micro-ohmmeter 1201 can be fixed to the connector 105 by an elastic strap 1202 .

[0105] In the embodiment of the present application, first, the ohmmeter can be connected to the fixing device, at this time, the clamping ground resistance between different positions of the to-be-tested equipment (for example, the energy storage sub-module) can be quickly measured through the fixing device with the ohmmeter, and the fixing of the ohmmeter on the to-be-tested equipment through the fixing device can complete the test of all clamping ground resistances in the energy storage sub-module by only one tester. Second, the fixing device can be firmly fixed on the surface of the to-be-tested equipment through the external suction cup or other fixing structure on the fixing device, thereby solving the problem that the test of the clamping ground resistance of the energy storage sub-module cannot be performed when working at a high place. Finally, the fixing device is installed with a fixed suction cup and a level, and can install equipment with high stability requirements such as an infrared thermal imager, thereby realizing the multipurpose of the fixing device.

[0106] In the embodiment of the present application, the fixing device can be any feasible frame structure, and the bottom is provided with a knob type or pressing type vacuum suction cup.

The surface of the fixing device is provided with a hook (i.e., a connecting piece), and a micro-ohmmeter and other test instruments can be firmly fixed on the fixing device through a bandage. The contact resistance test equipment can be embedded in the fixing device, which can not only perform clamping ground resistance test through self-test lines, but also can be connected to the four-wire measurement connection holes on the tool to achieve the purpose of extending the test lines. The fixing device can replace the detection equipment. The fixing device can not only be used as a carrier of a micro-ohmmeter and other detection equipment, but also can be used as an installation platform of an infrared thermal imager and a multi-channel temperature tester. The fixing device is internally provided with a simple level, and basic leveling operations can be performed.

[0107] The fixing device provided in the embodiment of the present application can be fixed on the surface of the to-be-tested equipment through a suction cup, so that the tester can focus on the test pen position, and the test result is more accurate. The number of testers can be reduced, and only one tester can complete the test of all clamping ground resistances through the fixing device installed with the detection equipment. The fixing device can install a common digital micro-ohmmeter on the market or a self-developed simple milliohm tester, and the fixing device can be switched according to the site conditions. The length of the internal beam and the longitudinal beam of the fixing device can be adjusted, different test instruments and equipment can be installed, and different test requirements can be met. The fixing device is internally provided with a level, which can ensure that the shooting picture of the infrared thermal imager remains stable. The fixing device can be folded by 90° through the adjustment of the longitudinal beam fixing screw (i.e., the longitudinal beam limiting piece), and the test of small-size test pieces or in a narrow space environment can be met.

[0108] Here, the fixing device can be reserved with a digital micro-ohmmeter placement position, the internal length (i.e. the length of the cross beam) of the fixing device is adjustable between 250mm-280mm, and the width (i.e. the length of the longitudinal beam) is adjustable between 150mm-180mm, which can be compatible with most digital micro-ohmmeters and electrical test equipment on the market.

[0109] The adjustable longitudinal and transverse beam design of the fixing device can also be used for the fixation of other equipment, such as multi-channel temperature measuring instruments and the like.
