[0026] The battery short-circuit test auxiliary device of the present invention includes: an electrode 1, which is movably disposed along a preset direction to have a contact position in contact with the battery and a separation position away from the battery; an elastic member 2, which is connected to the electrode 1 to drive the electrode 1 to move toward the separation position; and a driving member 3, at least a portion of which is movably disposed along a preset direction to drive the electrode 1 to move toward the contact position. Thus, when a short-circuit test is required on the battery, the electrode 1 is connected to a measuring instrument, and the driving member 3 drives the electrode 1 to overcome the resistance of the elastic member 2 and move to the contact position in contact with the battery, thereby connecting the electrode 1 to the battery for testing. After the test, the elastic member 2 drives the electrode 1 back to the separation position under elastic action, thereby resetting the electrode 1 of the battery short-circuit test auxiliary device for easy re-testing. This eliminates the need for operators to manually connect the electrode 1 to the battery, solving the problem of inconvenience in existing battery short-circuit testing processes.

[0027] Furthermore, using this mechanized battery short-circuit testing auxiliary device to perform short-circuit testing on the battery can improve the reliability of the contact between electrode 1 and the battery, thereby improving the testing accuracy. Compared with manual testing methods, it is also safer. The elastic element 2 can apply a force to electrode 1 pointing towards the separation position, thus providing a certain buffering effect on electrode 1 and helping to protect electrode 1 and the battery.

[0028] Specifically, the battery short-circuit test auxiliary device includes a bracket 4, which includes a support portion 41 and a limiting portion 42 arranged at intervals. The support portion 41 and the limiting portion 42 are connected by a guide portion 43. The electrode 1 includes a sliding portion 11, which is located between the support portion 41 and the limiting portion 42 and is slidably arranged along the guide portion 43. The first contact portion 12 is made of conductive material and is located on the side of the limiting portion 42 away from the support portion 41. The first contact portion 12 is connected to the sliding portion 11. An elastic member 2 is located between the sliding portion 11 and the limiting portion 42. One end of the elastic member 2 contacts the sliding portion 11, and the other end of the elastic member 2 contacts the limiting portion 42.

[0029] The sliding part 11 is provided with a third guide hole, and the guide part 43 passes through the third guide hole. The support part 41 is connected to the base 100 of the battery short circuit test auxiliary device.

[0030] To improve the stability of the elastic element 2 during installation, the elastic element 2 is a spring, which is sleeved on the guide portion 43; and / or, there are multiple guide portions 43. In this embodiment, there are two guide portions 43, and the connecting portion 13 is located between the two guide portions 43.

[0031] Specifically, electrode 1 includes a connecting part 13, the sliding part 11 is connected to the first contact part 12 through the connecting part 13, the limiting part 42 is provided with a first guide hole, and the connecting part 13 passes through the first guide hole.

[0032] In this embodiment, the support portion 41 is provided with a second guide hole; the connecting portion 13 is made of conductive material, the first end of the connecting portion 13 is connected to the first contact portion 12, and the second end of the connecting portion 13 extends through the second guide hole to the side of the support portion 41 away from the limiting portion 42; the driving member 3 includes a driving portion 31 and a second contact portion 32 made of conductive material, the second contact portion 32 is used for conductive connection with an external measuring instrument; the driving portion 31 is connected to the second contact portion 32 so that the driving portion 31 drives the second contact portion 32 to press the connecting portion 13 so that the electrode 1 moves to the contact position.

[0033] The second contact portion 32 is provided with a wiring portion for connecting to the measuring instrument. In this embodiment, the wiring portion is a terminal block.

[0034] Optionally, the sliding part 11, the first contact part 12, and the connecting part 13 are integral structures; and / or, the supporting part 41, the limiting part 42, and the guiding part 43 are integral structures. In this embodiment, the sliding part 11, the first contact part 12, the supporting part 41, and the limiting part 42 are all plate-shaped structures, and the connecting part 13 and the guiding part 43 are both column-shaped structures.

[0035] Specifically, there are two electrodes 1, which are spaced apart along a preset direction; there are two driving components 3, which are arranged in a one-to-one correspondence with the two electrodes 1.

[0036] In order to drive the movement of electrode 1 and improve the protection of the battery, the drive part 31 is a cylinder. The battery short circuit test auxiliary device includes an air supply switch 8, which is connected to the air supply line of the cylinder to control the opening and closing of the air supply line. The battery short circuit test auxiliary device includes a pressure measuring component 5, which is connected to the air supply line to measure the air pressure in the air supply line.

[0037] Specifically, the battery short-circuit test auxiliary device includes a support base 6, which has a groove for placing the battery. The shape of the groove wall matches the shape of the outer wall of the battery. In this embodiment, the battery is a cylindrical battery, and the groove on the support base 6 is part of the cylindrical surface.

[0038] The battery short-circuit testing auxiliary device includes a weighing component and a support base 6 for supporting the battery. The weighing component is located below the support base 6 to weigh the support base 6 and the battery located on it. Thus, when the battery is placed on the support base 6, it can be weighed by the weighing component, achieving simultaneous short-circuit testing and weighing without interference, thereby saving operation time and effectively improving testing efficiency. Optionally, the weighing component is an electronic scale or a pressure sensor.

[0039] The battery short-circuit test auxiliary device includes a display 7, which is connected to a weighing component to display the battery's weight information.

[0040] In addition, the battery short-circuit test auxiliary device includes an alarm component connected to a weighing component, so that when the weighing component detects that the weight of the battery exceeds the set range, the alarm component will issue an alarm signal.

[0041] Specifically, the weighing component, the display 7, and the pressure measuring component 5 are all mounted on the base 100 of the battery short-circuit test auxiliary device.

[0042] In this embodiment, to improve the protection of electrode 1 and battery, the driving member 3 is movably arranged along a preset direction. The battery short-circuit test auxiliary device includes an elastic pushing member that contacts the driving member 3 to apply a force toward the battery. Optionally, the elastic pushing member is a spring. Thus, when the driving member 3 drives electrode 1 to contact the battery, the elastic pushing member is compressed and deformed, causing the driving member 3 to move away from the battery, which can buffer and protect the battery, preventing damage. Specifically, the main body of the battery short-circuit test auxiliary device is provided with a sliding guide extending along a preset direction. The driving member 3 is slidably arranged along the sliding guide, which can be a slide rail or a slide groove.

[0044] The battery short-circuit test auxiliary device of the present invention includes: an electrode 1, which is movably disposed along a preset direction to have a contact position in contact with the battery and a separation position away from the battery; an elastic member 2, which is connected to the electrode 1 to drive the electrode 1 to move toward the separation position; and a driving member 3, at least a portion of which is movably disposed along a preset direction to drive the electrode 1 to move toward the contact position. Thus, when a short-circuit test is required on the battery, the electrode 1 is connected to a measuring instrument, and the driving member 3 drives the electrode 1 to overcome the resistance of the elastic member 2 and move to the contact position in contact with the battery, thereby connecting the electrode 1 to the battery for testing. After the test, the elastic member 2 drives the electrode 1 back to the separation position under elastic action, thereby resetting the electrode 1 of the battery short-circuit test auxiliary device for easy re-testing. This eliminates the need for operators to manually connect the electrode 1 to the battery, solving the problem of inconvenience in existing battery short-circuit testing processes.
