[0002] Battery testing is becoming more and more important with the development of the new energy industry. Traditional destructive testing cannot obtain the overall status of internal defects in the battery. Therefore, ultrasonic non-destructive battery testing came into being. Ultrasonic non-destructive battery testing uses ultrasonic imaging technology to accurately reflect the internal structural distribution of the battery and the images of each interface, making it easier to accurately find the internal defects of the battery.

[0003] During ultrasonic non-destructive battery testing, the ultrasonic probe is directed toward the battery to be tested, and the battery to be tested is scanned by a driving device. For example, CN208297685U discloses a non-destructive testing device for obtaining the internal state distribution of a lithium-ion battery, which discloses a probe fixing frame for fixing the ultrasonic probe.

[0004] However, this fixing method is relatively simple, cannot adjust the angle of the probe, and has poor adaptability. Summary of the invention

[0037] Figure 1 The main structure diagram of the probe angle adjustment device of an embodiment of the present application is shown. Figure 2 A side cross-sectional view of the probe angle adjustment device according to an embodiment of the present application is shown. Figure 1 and Figure 2 As shown, the probe angle adjustment device includes: a locking module 100 and a retaining frame 200; the main body of the locking module 100 is a shell structure, the inner wall of the cavity of the locking module 100 is a concave spherical surface, and the locking module 100 is provided with a first clearance hole 130, and the first clearance hole 130 is connected to the cavity of the locking module 100; the retaining frame 200 is located inside the cavity of the locking module 100, and the outer wall of the retaining frame 200 is a convex spherical surface, and the outer wall of the retaining frame 200 matches the inner wall of the cavity of the locking module 100; the retaining frame 200 is provided with a mounting hole, and the mounting hole is suitable for mounting the adapted ultrasonic probe 300, and the mounting hole faces the first clearance hole 130.

[0038] The present application is applicable to adjusting the orientation angle of the adapted ultrasonic probe 300. By setting the retaining frame 200 inside the cavity of the locking module 100, the locking module 100 and the retaining frame 200 are respectively provided with matching concave spherical cavity inner sidewalls and convex spherical outer sidewalls, so that the retaining frame 200 can rotate in the cavity of the locking module 100 with the center of the sphere where the spherical surface is located as the rotation center, thereby achieving the adjustment of the orientation angle of the ultrasonic probe 300 set in the mounting hole. Among them, the detection end of the ultrasonic probe 300 set in the mounting hole protrudes out of the locking module 100 through the first clearance hole 130, so that the detection end of the ultrasonic probe 300 is always facing the outside of the locking module 100 during the adjustment process. Compared with the traditional installation method of the ultrasonic probe 300, the present application can adjust the orientation angle of the installed ultrasonic probe 300 to improve adaptability.

[0039] In a possible implementation, the locking module 100 is further provided with a second clearance hole, the second clearance hole is connected to the cavity of the locking module 100, and the first clearance hole 130 is arranged opposite to the second clearance hole; the mounting hole is arranged through the retaining frame, and the two ends of the mounting hole are respectively facing the first clearance hole 130 and the second clearance hole. Figure 1 As shown, the adapted ultrasonic probe 300 is set through the mounting hole through the retaining frame 200, and the locking module 100 is matched with it to respectively open the first clearance hole 130 and the second clearance hole, so that the detection end and the wiring end of the ultrasonic probe 300 are respectively protruded from the first clearance hole 130 and the second clearance hole, which is convenient for the installation and wiring of the adapted ultrasonic probe 300.

[0040] In a possible implementation, the holder 200 is provided with a mounting portion, which is suitable for fixing the adapted ultrasound probe 300 to the holder 200; the mounting portion is located on a side of the holder 200 close to the second clearance hole, and the mounting portion protrudes out of the second clearance hole. By providing the mounting portion, the adapted ultrasound probe 300 is conveniently detachably connected to the holder 200.

[0041] Furthermore, the mounting portion includes an external threaded ring 220 and a nut 230 ; the external threaded ring 220 is arranged on the side of the retaining frame 200 close to the second clearance hole, and the external threaded ring 220 protrudes out of the second clearance hole; the nut 230 matches the external threaded ring 220 , and the nut 230 is sleeved on the external threaded ring 220 .

[0042] like Figure 2As shown, the external thread ring 220 is coaxially arranged with the mounting hole, and the inner diameter of the external thread ring 220 is larger than the inner diameter of the mounting hole, so that after the ultrasonic probe 300 is inserted into the mounting hole, the protrusion close to the wiring end of the ultrasonic probe 300 is located inside the external thread ring 220 and abuts against the edge of the opening of the mounting hole.

[0043] In a possible implementation, the locking module 100 is provided with an adjustment hole 140, and the holder 200 is provided with an adjustment handle 210; one end of the adjustment handle 210 is connected to the outer wall of the holder 200, and the other end of the adjustment handle 210 protrudes out of the locking module 100 through the adjustment hole 140. The main body of the adjustment handle 210 is cylindrical, one end of the adjustment handle 210 is connected to the holder 200, and the other end protrudes out of the locking module 100 through the adjustment hole 140. By providing the adjustment handle 210, the rotation angle of the holder 200 can be easily adjusted.

[0044] The inner diameter of the adjustment hole 140 is larger than the outer diameter of the adjustment handle 210 to ensure the adjustment range of the retaining frame 200 .

[0045] In a possible implementation, the main body of the holder 200 is cylindrical, the side of the cylindrical structure of the holder 200 is a convex spherical surface, and the mounting holes are provided at both end surfaces of the cylindrical structure of the holder 200.

[0046] Furthermore, the cavity of the locking module 100 is cylindrical; the side surface of the cylindrical structure of the cavity of the locking module 100 is a concave spherical surface, so that it matches the retaining frame 200 of the cylindrical structure.

[0047] Furthermore, a preset gap is provided between the end face of the cylindrical structure of the retaining frame 200 and the inner inner wall of the cavity of the locking module 100. By setting the gap, a movable space is provided for the retaining frame 200 with a cylindrical structure in the cavity of the locking module 100, so that the retaining frame 200 can be rotated for angle adjustment.

[0048] In a possible implementation, the locking module 100 includes a first locking shell 110 and a second locking shell 120; the first locking shell 110 and the second locking shell 120 are interlocked and detachably connected.

[0052] In a possible implementation, the bolt 150 is a spring screw. The first locking shell 110 and the second locking shell 120 are connected by the spring screw. By providing the spring screw, in the default state, the first locking shell 110 and the second locking shell 120 press the retaining frame 200 to keep it stable. When the first locking shell 110 and the second locking shell 120 are respectively applied with mutually divergent forces to compress the spring screw, the first locking shell 110 and the second locking shell 120 release the clamping of the retaining frame 200, so that the retaining frame 200 can be rotated to adjust the angle.
