[0020] Please refer to Figures 1 to 2 This application discloses a battery testing system connection mechanism in one embodiment. This mechanism connects a battery testing device and a battery under test. The connection mechanism includes an electrical connection docking component 10 and a probe docking component 20. The electrical connection docking component 10 connects to the electrodes of the fixedly mounted battery under test. For example, when the battery under test is fixed on a battery testing fixture, the electrical connection docking component 10 connects to the electrodes of the battery under test. When testing the battery under test, the probe docking component 20 is docked with the electrical connection docking component 10, thus enabling testing of the battery under test. This solves the problem of manually connecting the battery testing device and the battery under test, simplifies the testing procedure, and improves testing efficiency.

[0021] The electrical connection docking assembly 10 is arranged on the battery test fixture and connected to the electrode of the battery under test. The electrical connection docking assembly 10 includes a current connector 11 for connecting to the electrode of the battery under test and a performance test connector 12 for connecting to the performance test piece. Here, the electrode refers to the positive electrode and negative electrode of the battery under test, and the performance test piece refers to the component used to collect parameters such as current, voltage, pressure, and temperature of the battery under test. These are all existing technologies and will not be described in detail here.

[0022] The probe docking assembly 20 includes a probe group 21 electrically connected to the battery testing equipment and a drive structure 22 that drives the probe group 21 to be close to or away from the electrically connected docking assembly 10. The probe group 21 includes a current docking probe that docks with the current docking connector 11 and a performance test probe 213 that docks with the performance test docking connector 12.

[0023] In one embodiment, the probe assembly 21 further includes a mounting plate 214 connected to the drive structure 22 and a fixing plate 215 mounted on the mounting plate 214. A notch 2141 is formed on the mounting plate 214. The performance test probe 213 is arranged on the fixing plate 215, and the projection of the performance test probe 213 overlaps with the projection of the notch 2141 in the moving direction of the probe assembly 21. With this arrangement, the connection between the performance test probe 213 and the battery testing equipment can be arranged at the notch 2141, facilitating the connection or disconnection of the performance test probe 213 from the battery testing equipment, thus saving space and reducing the size of the connection mechanism of the battery testing system.

[0024] In one embodiment, current docking probes are arranged on the mounting plate 214 and located on both sides of the notch 2141. The current docking probes are arranged on both sides of the notch 2141 so that when the current connector 11 abuts against the current docking probes, the force between the probe docking assembly 20 and the electrical connection docking assembly 10 is balanced, ensuring a stable connection between the two.

[0025] In one embodiment, the current docking probe includes an electrode probe 211 and a spring 212 sleeved on the electrode probe 211. The spring 212 is arranged near the electrical connection docking assembly 10 and is always in a compressed state. The two ends of the spring 212 abut against the mounting plate 214 and the electrode probe 211, respectively. The spring 212 dampens the electrode probe 211, preventing rigid collisions when the electrode probe 211 docks with the current docking connector 11, which could damage the electrode probe 211. At the same time, after the two abut, the spring 212 keeps the electrode probe 211 pressed against the current docking connector 11, preventing separation and poor contact that could affect the testing process.

[0026] In one embodiment, a test connection line 216 is provided on the side of the electrode probe 211 away from the electrical connection docking assembly 10. The test connection line 216 is used to connect to the battery testing equipment. The test connection line 216 is a copper strip, and mounting holes 2161 are provided at both ends of the copper strip to facilitate fixed connection with the electrode probe 211 and the battery testing equipment by screws.

[0027] In one embodiment, the driving structure 22 includes a motion slide rail 223, a slider 224 disposed on the motion slide rail 223, and a power component for driving the slider 224 to move. The probe assembly 21 is arranged on the slider 224. By driving the slider 224 to move on the motion slide rail 223 through the power component, the probe assembly 21 is moved, effectively avoiding misalignment during the docking process.

[0028] In one embodiment, the power component is a cylinder 221. A motion push rod 222 is connected between the output shaft of the cylinder 221 and the slider 224. The motion push rod 222 connects the cylinder 221 and the slider 224, which facilitates the control of the distance between the cylinder 221 and the probe group 21 and is beneficial to the layout of various components.

[0029] In one embodiment, two sets of motion slide rails 223 are provided, and the two sets of sliders 224 are connected and fixed by a connecting plate 225. The motion push rod 222 is fixedly connected to the connecting plate 225 and is located in the middle of the two sets of motion slide rails 223. By cooperating with the two sets of motion slide rails 223, the guiding effect on the movement direction of the probe group 21 is further improved, ensuring stable docking of the electrical connection docking assembly 10 and the probe docking assembly 20.

[0030] This application achieves automated connection or disconnection between the battery testing equipment and the battery under test by setting an electrical connection docking component on the battery testing fixture to electrically connect the battery under test, and by driving a probe group electrically connected to the battery testing equipment to move closer to or away from the electrical connection docking component through a driving structure. This simplifies the connection method between the battery testing equipment and the battery under test, improves testing efficiency, and reduces errors caused by human intervention.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
