Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 6 In this embodiment, a compatible multi-channel equidistant test press mechanism includes a mounting frame assembly 1, a driving assembly 2 is mounted on the inner side of the mounting frame assembly 1, a depth adjustment assembly 3 is mounted on the upper side of the mounting frame assembly 1, and a negative probe module assembly 4 and a positive probe module assembly 5 are mounted on the upper side of the driving assembly 2. The driving assembly 2 drives the negative probe module assembly 4 and the positive probe module assembly 5 to move forward or backward, and the depth adjustment assembly 3 forms an adjustment limit for the negative probe module assembly 4 and the positive probe module assembly 5.

[0029] It should be noted that the negative probe module assembly 4 and the positive probe module assembly 5 are respectively arranged on both sides of the top of the mounting frame assembly 1, and the number of depth adjustment assemblies 3 is set to four groups, and the four groups of depth adjustment assemblies 3 are distributed in pairs on both sides of the negative probe module assembly 4 and both sides of the positive probe module assembly 5.

[0030] In this embodiment, the depth adjustment assembly 3 includes a first adjusting nut 3-1, a mounting block 3-2, a first adjusting screw 3-3, a follow-up limit block 3-4 and a fixed block 3-5. The mounting block 3-2 is fixedly installed on the outside of the mounting frame assembly 1, the first adjusting nut 3-1 is arranged on the outside of the mounting block 3-2, the first adjusting screw 3-3 passes through the mounting block 3-2 and is fixedly connected to the first adjusting nut 3-1, the fixed block 3-5 is fixedly installed on the outside of the mounting frame assembly 1, the first adjusting screw 3-3 is connected to the mounting block 3-2 and the fixed block 3-5 through bearings, the follow-up limit block 3-4 is slidably installed on the upper side of the mounting frame assembly 1, and the follow-up limit block 3-4 is connected to the first adjusting screw 3-3 through a bearing.

[0031] In this embodiment, the negative probe module assembly 4 includes a negative probe module frame assembly 4-1, a second adjusting screw 4-2, an adjustment indicator plate 4-3, a second adjusting nut 4-4, a position display 4-5, a double pitch screw assembly 4-6 and a probe assembly 4-7. The negative probe module frame assembly 4-1 is fixedly mounted on the upper side of the drive assembly 2, the second adjusting screw 4-2 is rotatably mounted on the negative probe module frame assembly 4-1, the adjustment indicator plate 4-3 is arranged on one side of the second adjusting screw 4-2, the second adjusting nut 4-4 is installed at one end of the position display 4-5, the position display 4-5 is connected to the second adjusting screw 4-2, a transmission shaft is sleeved on the outer side of the second adjusting nut 4-4, the double pitch screw assembly 4-6 is connected to the transmission shaft, and the probe assembly 4-7 is threadedly mounted on the outer side of the pitch screw assembly 4-6.

[0032] Among them, the double-pitch screw assembly 4-6 is designed with two sections of threads with different pitches, which are 1.0mm and 2.0mm respectively. There are two groups of probe assemblies 4-7 on each group of double-pitch screw assemblies 4-6, one group of probe assemblies 4-7 is installed in the 1.0 pitch section, and the other group of probe assemblies 4-7 is installed in the 2.0 pitch section. When the 1.0 section transmits 1mm, the 2.0 section transmits 2mm, completing equal spacing adjustment.

[0033] It should be noted that the overall structure of the positive probe module assembly 5 is the same as that of the negative probe module assembly 4. A transmission component is arranged between the depth adjustment assemblies 3 on both sides of the negative probe module assembly 4 and the positive probe module assembly 5. The transmission component includes a sprocket 3-6 and a chain 3-7. The sprocket 3-6 cooperates with the chain 3-7. The first adjustment screw 3-3 passes through the fixed block 3-5 and is connected to the sprocket 3-6. Through the transmission action of the sprocket 3-6 and the chain 3-7, the depth adjustment assembly 3 on both sides of the negative probe module assembly 4 or the positive probe module assembly 5 is convenient for synchronous adjustment.

[0034] The working principle of the above embodiment is:

[0035] When in use, when the number of agreed test channels changes, the double pitch screw components 4-6 in the probe module assembly are appropriately increased or decreased to match the current number of channels;

[0036] Taking the negative electrode probe module assembly 4 as an example, when the model of the protocol-compatible battery cell is changed, resulting in a change in the battery cell spacing, the relative spacing of the probe assembly 4-7 needs to be adjusted, and the second adjustment nut 4-4 is screwed with a tool. When the second adjustment nut 4-4 is screwed, the shaft fitted on the second adjustment nut 4-4 drives the double-pitch screw assembly 4-6 to rotate, and the probe spacing is adjusted under the transmission of the thread;

[0037] The double-pitch screw assembly 4-6 is designed with two sections of threads with different pitches, 1.0mm and 2.0mm respectively. One set of probes is installed in the 1.0 pitch section, and another set of probes is installed in the 2.0 pitch section. When the 1.0 section transmits 1mm, the 2.0 section transmits 2mm, thereby achieving equal spacing adjustment. When adjusting, the current adjustment amount can be confirmed according to the value displayed on the position display 4-5;

[0038] When the model of the cell compatible with the protocol is changed, resulting in a change in the cell height, thereby changing the center height of the pole, the height of the probe assembly 4-7 needs to be adjusted accordingly. The height of the entire probe module can be adjusted by using a tool to screw the second adjustment screw 4-2. In the height adjustment, an adjustment indicator plate 4-3 and an engraved ruler are designed, and the adjustment value can be determined by observing the alignment of the scale of the indicator plate;

[0039] When the model of the cell compatible with the protocol is changed, resulting in a change in the total length of the cell, it is necessary to change the distance of the probe module forward pressing, use a tool to screw the first adjustment nut 3-1, drive the first adjustment screw 3-3 to rotate, and change the relative position of the follow-up limit block 3-4 through the transmission of the screw thread. When adjusting, the scale engraved below the follow-up limit block 3-4 can be observed to confirm the adjustment value;

[0040] The adjustment process of the positive probe module assembly 5 is the same as that of the negative probe module assembly 4. When the battery cell changes, the positive and negative probe module assemblies are adjusted uniformly.

[0041] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller is a conventional known device, and there is an existing disclosed power connection technology. Therefore, the text will not go into too much detail on its specific structural composition and working principle.
