[0033] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] Example 1:

[0036] This embodiment provides a probe holder, including:

[0037] The first fastener 1 has a first adjusting mounting hole 3, which is used to achieve adjustable connection with an external structure along the length direction X.

[0038] The second fixing member 2 is provided with a second adjustment mounting hole 4, which is used to realize the adjustable connection with the probe module along the width direction Y.

[0039] The first fixing member 1 is connected to the second fixing member 2, and the first fixing member 1 includes a height adjustment structure that is adjustable along the height direction Z.

[0040] In this technical solution, when the probe holder is in use, it is first connected to the external structure by a screw passing through the first adjustment mounting hole 3 along the height direction Z. The first fixing member 1 abuts against the external structure and the head of the screw on both sides along the height direction Z, thus fixing the first fixing member 1 to the external structure. Then, a screw passes through the second adjustment mounting hole 4 along the height direction Z to connect to the probe module. The second fixing member 2 abuts against the probe module and the head of the screw on both sides along the height direction Z, thus fixing the second fixing member 2 to the probe assembly. This allows the probe module to be fixedly connected to other external structures via the probe holder.

[0041] When the relative position of the probe module and the external structure in the length direction X and width direction Y needs to be adjusted, the screws in the first adjustment mounting hole 3 and the second adjustment mounting hole 4 can be loosened. Then, the positions of the screws in the first adjustment mounting hole 3 and the second adjustment mounting hole 4 can be adjusted by moving them. Finally, the screws are tightened to secure the connection, thereby realizing the position adjustment of the probe module in the length direction X and width direction Y.

[0042] When the relative position of the probe module and the external structure in the height direction Y needs to be adjusted, the height of the first fixing member 1 is adjusted by the height adjustment structure, so that the position of the second fixing member 2 connected to the first fixing member 1 in the height direction Z changes, thereby realizing the position adjustment of the probe module in the height direction Z.

[0043] In summary, by opening a first adjustment mounting hole 3 on the first fixing member 1, opening a second adjustment mounting hole 4 on the second fixing member 2, and setting a height adjustment structure on the first fixing member 1, the probe module can achieve position adjustment in three axes when connected and fixed to other mechanisms through the probe fixing seat. This is convenient and practical, ensuring that the probe module can avoid the QR code on the battery and maintain a suitable height distance from the battery during use, thereby preventing the battery QR code from being crushed and the battery surface from being imprinted, effectively improving the production quality of the battery.

[0044] Example 2:

[0045] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] Furthermore, the first fixing member 1 includes a first component 11 and a second component 12 that are separately arranged along the height direction Z, and the height adjustment structure is located between the first component 11 and the second component 12.

[0047] In this technical solution, the first fixing member 1 is divided into a first component 11 and a second component 12 along the height direction Z. A height adjustment structure is provided between the first component 11 and the second component 12 to adjust the distance between the first component 11 and the second component 12 along the height direction Z, thereby realizing the position adjustment of the probe module in the height direction Z.

[0048] The height adjustment structure can consist of a shim 5 and a placement slot 6, such as... Figure 3 As shown, a placement groove 6 is provided between the first component 11 and the second component 12. A shim 5 is installed in the placement groove 6. The shim 5 is used to increase the distance between the first component 11 and the second component 12 in the height direction Z, thereby changing the height of the first fixing member 1, and thus realizing the position adjustment of the probe module on the second fixing member 2 in the height direction Z.

[0049] The height adjustment structure can also consist of a screw 7 and a threaded hole 8, such as... Figure 4 As shown, the screw 7 is mounted on the first component 11, and the threaded hole 8 passes through the second component 12 along the height direction Y. The screw 7 and the threaded hole 8 are threadedly connected. By adjusting the amount of threaded connection between the screw 7 and the threaded hole 8, the distance between the first component 11 and the second component 12 in the height direction Z is changed, thereby changing the height of the first fixing member 1, and thus realizing the position adjustment of the probe module on the second fixing member 2 in the height direction Z.

[0050] Example 3:

[0051] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] Furthermore, the first component 11 is provided with a first connecting part 13, which has a multi-step structure along the height direction Z;

[0053] The second component 12 is provided with a second connecting part 14, and the second connecting part 14 also has a multi-step structure along the height direction Z.

[0054] The first component 11 and the second component 12 are adapted and abutted by a multi-step structure, and a height adjustment structure is formed between the first connecting part 13 and the second connecting part 14. The first adjustment mounting hole 3 is set through the first component 11 and the second component 12 along the height direction Z. The second fixing member 2 is connected to the first component 11 or the second component 12.

[0055] In this technical solution, such as Figure 2 , Figure 5 , Figure 6 As shown, the height of the first fixing member 1 is adjusted by adjusting the step-shaped first connecting part 13 and the step-shaped second connecting part 14 to fit and abut against each other at different positions. Then, by setting screws to pass through the first adjustment mounting hole 3 to connect with the external structure, the first component 11 and the second component 12 are pressed against each other along the height direction Z, so that the first fixing member 1 is fixedly connected to the external structure while ensuring that the first component 11 and the second component 12 will not be offset.

[0056] With this structural design, when changing the position of the probe module, the position of the probe module in the height direction Z can be adjusted without setting shims 5 or screws 7. The structure is simple, the adjustment is convenient, and the practicality is high.

[0057] Example 4:

[0058] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, the first adjustment mounting hole 3 forms a first U-shaped connecting groove 31 on the first component 11 and a second U-shaped connecting groove 32 on the second component 12.

[0060] This structural design allows the probe holder to be adjusted in height or disassembled without completely removing the screws. Simply loosen the screws and then separate the first component 11 and the second component 12 along the first U-shaped connecting groove 31 and the second U-shaped connecting groove 32. This avoids stripping the screw holes on the external structure due to repeated disassembly and reassembly of the probe holder, reducing the risk of the probe module falling off.

[0061] Example 5:

[0062] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] Furthermore, the second fastener 2 and the first component 11 are an integral structure, or the second fastener 2 and the second component 12 are an integral structure.

[0064] This structural design effectively enhances the connection strength between the first fixing member 1 and the second fixing member 2, making the probe holder more robust and stable during use.

[0065] Example 6:

[0066] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] Furthermore, both the first adjustment mounting hole 3 and the second adjustment mounting hole 4 can be either rectangular or racetrack-shaped. This structural design allows the probe holder to be adjustable along the length direction X to connect to an external structure and adjustable along the width direction Y to connect to the probe module. The structure is simple and easy for operators to adjust.

[0068] Preferably, the first adjustment mounting hole 3 and the second adjustment mounting hole 4 are racetrack-shaped. This structural design prevents sharp corners from forming on the inner walls of the first adjustment mounting hole 3 and the second adjustment mounting hole 4, effectively reducing stress concentration and lowering the risk of cracks and fractures.

[0069] Example 7:

[0070] This embodiment provides a probe holder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0071] Furthermore, the length of the first fastener 1 along the length direction X is L1, the length of the second fastener 2 along the length direction X is L2, and the ratio of the length of the second fastener 2 to the length of the first fastener 1 is 1 / 2 < L2 / L1 < 3 / 4.

[0072] This structural design avoids stress concentration caused by excessive length of the first fastener 1 or the second fastener 2, prevents breakage at the connection between the first fastener 1 and the second fastener 2, and effectively improves the connection strength between the first fastener 1 and the second fastener 2.

[0073] Example 8:

[0074] This embodiment provides a detection mechanism, which, in addition to the probe holder included in any one of the embodiments 1-7 above, also has the following technical features.

[0076] Furthermore, the needle bed assembly and the probe holder, as well as the probe assembly and the probe holder, are all connected by screws. The first fixing member 1 is connected to the needle bed assembly by screws passing through the first adjustment mounting hole 3, and the second fixing member 2 is connected to the probe assembly by screws passing through the second adjustment mounting hole 4.
