DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described below in conjunction with the drawings and examples.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description, the present application will be further described in detail below in conjunction with the drawings.

[0031] A battery testing device for repairing new energy vehicles, such as Figures 1-7 As shown, the system includes a support body 1, a side clamping detection device 2, a compression detection assembly 3, an expansion detection pressure plate 4, and a pressure plate lifting device 5. The support body 1 contains a lifting assembly 7. The side clamping detection devices 2 are installed opposite each other on both sides of the support body 1. The expansion detection pressure plate 4 is movably mounted on the support body 1 via support columns. The support body 1 is equipped with the compression detection assembly 3, a linear displacement sensor 8, and the oppositely arranged pressure plate lifting device 5. Both the pressure plate lifting device 5 and the linear displacement sensor 8 are connected to the expansion detection pressure plate 4. The compression detection assembly 3 penetrates the expansion detection pressure plate 4. A control display panel 9 is installed on the support body 1. The control display panel 9 is communicatively connected to the side clamping detection device 2, the compression detection assembly 3, the pressure plate lifting device 5, the lifting assembly 7, and the linear displacement sensor 8. Operators can visually view various detection data through the control display panel 9. The linear displacement sensor 8 is a KTC pull rod type. The stretching end is connected to the expansion detection plate 4. When the battery expands during charging, it pushes the expansion detection plate 4 to rise, thereby driving the stretching end of the linear displacement sensor 8 to take a measurement. The support column is located at the four corners of the support body 1. The support body 1 includes a bottom and an upper concave shell. The lifting component 7 is located inside the bottom. The two side clamping detection devices 2 are installed opposite each other on the two sides of the upper concave shell. They can not only effectively clamp and fix the battery to prevent it from shifting during the detection process, but also detect and feedback the magnitude of the clamping force in real time, avoiding excessive clamping and preventing battery instability caused by loose clamping. The pressure plate lifting device 5 is located at the top of the upper concave shell, and its compression detection component 3 is located at the center of the top of the upper concave shell. The compression detection component 3 can monitor the battery's reaction when subjected to external pressure. The expansion detection plate 4 and the linear displacement sensor 8 can monitor the expansion of the battery during the charging process in real time, thereby comprehensively evaluating the battery's safety performance.

[0032] The side clamping detection device 2 comprises a driving cylinder 21, a buffer non-slip pad 22, a first pressure sensor 23 and a plurality of buffer springs 24. The first pressure sensor 23 is fixedly installed at the telescopic end of the driving cylinder 21. The plurality of buffer springs 24 are installed between the telescopic end of the driving cylinder 21 and the buffer non-slip pad 22. The single buffer spring 24 is located between the first pressure sensor 23 and the buffer non-slip pad 22. The non-slip pad not only provides the necessary friction force to prevent the object from sliding during clamping, but also protects the surface of the object. The driving cylinder 21 is used as the clamping device to provide stable and controllable clamping force. When the non-slip pad is subjected to the clamping force, the buffer spring 24 will first elastically deform to absorb part of the impact force. The buffer spring 24 located on the first pressure sensor 23 is stressed and directly transmits the force to the first pressure sensor 23 for detection. The pressure signal is fed back to the control display panel 9 as an electric signal. At the same time, the elastic deformation of the buffer spring 24 can also adjust the size of the clamping force to a certain extent, so that the clamping process is more stable and gentle. The plurality of buffer springs 24 are uniformly distributed between the telescopic end of the driving cylinder 21 and the buffer non-slip pad 22. The remaining buffer springs 24 are all installed with telescopic columns. Except that the buffer spring 24 located between the first pressure sensor 23 and the buffer non-slip pad 22 is not installed with a telescopic column, the remaining buffer springs 24 are all installed with telescopic columns to avoid the dislocation of the buffer non-slip pad 22, which leads to the failure of clamping. When the battery is charged and expands, the plurality of buffer springs 24 can be used for buffering to increase the service life of the device.

[0033] The pressing plate lifting device 5 comprises a driving motor 51, an upper supporting plate 52, a connecting column 53 and a lower supporting plate 54. The driving motor 51 is installed at the top of the supporting main body 1. A threaded rod is fixedly installed at the output end of the driving motor 51. The threaded rod is connected with the oppositely arranged connecting columns 53 through the upper supporting plate 52. The connecting columns 53 penetrate the expansion detection pressing plate 4. The connecting columns 53 are fixedly installed with the lower supporting plate 54 at the penetrating end. The lower supporting plate 54 abuts against the lower surface of the expansion detection pressing plate 4 through the connecting column 53. The two connecting columns 53 are symmetrically arranged through the threaded rod. The threaded rod is driven to rotate by the driving motor 51. Since the connecting columns 53 are fixed, the rotating force is converted into the force for the up-and-down movement of the connecting columns 53, so as to drive the expansion detection pressing plate 4 to lift. The battery can be easily taken out after the detection is completed without being hindered by the expansion detection pressing plate 4. The expansion detection pressing plate 4 is in the form of natural dropping. When the battery is charged and expands, the expansion detection pressing plate 4 can be easily lifted. The expansion detection pressing plate 4 easily slides on the connecting columns 53. The pressing plate lifting device 5 only has the lowest limit function when the driving motor 51 is not working.

[0035] The lifting assembly 7 comprises four push cylinders 71 and a placing plate 72, the four push cylinders 71 are installed at the four corners inside the support body 1, the push cylinders 71 are movably installed at the bottom surface of the placing plate 72, the four push cylinders 71 jointly operate to ascend horizontally, and the staff only needs to simply control the start and stop of the lifting assembly 7 to complete the lifting and taking process of the battery, the four push cylinders 71 are divided into two groups, and the placing plate 72 is tilted by stopping the movement of one group and continuing to lift the other group, so that the battery slides, and the staff can more easily take the battery, which is more labor-saving and efficient, especially for the battery with large weight. The lifting assembly 7 is located below the two side clamping detection devices 2, and can be used to adjust the height or position of the battery during the detection process to adapt to batteries of different sizes and types.

[0036] The parts and devices all adopt conventional models in the prior art, and the circuit connection adopts a conventional connection mode in the prior art, which will not be described in detail here. The contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0037] Working principle: the staff puts the battery to be detected on the placing plate 72, and then starts the side clamping detection device 2 to clamp the battery by controlling the display panel 9, adjusts the clamping force according to the feedback of the side clamping detection device 2, avoids too much force on both sides of the battery, starts the electric push rod 31 to extrude the battery after clamping is completed, and feeds back the detected value to the display panel 9 through the second pressure sensor 32, and stops extrusion when the electric push rod 31 is retracted after detection is completed.

[0038] Further, the starting pressure plate lifting device 5 lowers the expansion detection pressure plate 4 until it abuts against the top of the battery, at which time the pressure plate lifting device 5 is stopped and the battery is started to be charged and discharged, and the thickness of the battery changes when it is charged and discharged, thereby driving the expansion detection pressure plate 4 to rise, and when the expansion detection pressure plate 4 rises, the telescopic end of the linear displacement sensor 8 is moved, at which time the linear displacement sensor 8 feeds back a signal to the control display panel 9, and the expansion force detection is completed.

[0039] After the battery is completely detected, the staff starts the pressure plate lifting device 5 to lift the expansion detection pressure plate 4, and releases the clamping of the side clamping detection device 2, at which time the lifting assembly 7 is started, and the pushing cylinder 71 of the lifting assembly 7 pushes the battery placing plate 72 on which the battery is placed, and pushes it out to facilitate the staff to take it.
