Technical Field

[0001] This utility model relates to the field of battery capacity testing cabinet technology, specifically a probe structure for a battery capacity testing cabinet. Background Technology

[0002] With economic development and the significant increase in lithium battery production capacity, the requirements for battery performance testing are becoming increasingly stringent. When charging and discharging batteries, the capacity testing cabinet often suffers from circuit burning or damage due to short circuits, overcharging, reverse charging, and other reasons. Battery probes are used for battery formation, capacity testing, and detection. As a connector between the transmission wire and the battery tabs, they achieve low-resistance current transmission by piercing the oxide layer on the surface of the battery tabs. A probe structure for battery capacity testing cabinets is needed.

When these conductive elements are damaged, they cannot be replaced, rendering the entire battery probe unusable. Furthermore, existing probe structures are not sufficiently stable during installation, making them inconvenient to operate. They also lack adequate anti-loosening protection, leading to accidental disconnections between the wires and fuses. Finally, existing probe structures are difficult to maintain, rendering them impractical in everyday use. Utility Model Content

The surface of the voltage acquisition rod is fitted with a buffer spring, one end of which is fixed to the surface at the bottom of the insulating plate, and the bottom end of which is fixed to the surface of the probe head.

[0007] Preferably, the stable mounting assembly is disposed on the surface of the insulating plate.

[0009] Preferably, a guide slider is installed on the surface of the probe rod, and a guide groove is provided on the inner wall of the U-shaped mounting bracket. The guide groove and the surface of the guide slider slide against each other. The inner wall of the U-shaped mounting bracket is provided with a groove, and an arc-shaped clamp is provided inside the groove. The arc-shaped clamp slides against the inner wall of the groove.

[0010] Preferably, the probe rod body has an arc-shaped groove on its surface, the arc-shaped groove and the surface of the arc-shaped clip are engaged with each other, and the inner wall of the groove is equipped with a telescopic spring, one end of the telescopic spring is fixed to the surface of the arc-shaped clip.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the probe structure used in the battery capacity testing cabinet not only allows the probe rod and insulating plate to be installed in the designated position of the capacity testing cabinet, making the probe structure more convenient to operate, preventing the wires from coming loose from the inside of the terminal block, and preventing accidental disconnection between the wires and the fuse, but also makes it easy for users to remove the probe rod, insulating plate and probe head from the surface of the U-shaped mounting bracket for inspection, maintenance or replacement, making the probe structure more practical to use;

[0014] 1. With a secure installation mechanism, the user can tighten the fastening studs on the surface of the insulation board, causing the fastening studs to move the stabilizing suction cup inside the installation slot. This allows the fastening studs to move the stabilizing suction cup until it contacts the inner wall of the distribution cabinet. At this point, the stabilizing suction cup moves the anti-detachment clip away from the anti-detachment slot, thus installing the probe rod in the designated position in the distribution cabinet. This achieves the function of securely installing the probe structure, making it easier to operate the probe structure when using it by installing the probe rod and insulation board in the designated position in the distribution cabinet.

[0015] 2. By setting up a precise detection mechanism, the sealing gasket is driven to move under the elastic force of the extension spring inside the sealing frame. This causes the sealing gasket to move the sliding block inside the fixed groove. Under the combined action of the sliding block and the fixed groove, the sealing gasket is guided. Under the elastic force of the extension spring inside the sealing frame, the sealing gasket can clamp the wire inside the terminal block, preventing the wire from coming loose during use and affecting the performance. This achieves the anti-loosening function of the probe structure, thus preventing the wire from coming loose from the inside of the terminal block during use. This also prevents the wire and fuse from accidentally breaking during use.

[0016] 3. With a maintenance and replacement mechanism, the user pulls down the insulating plate, causing it to move the probe rod. The probe rod then moves the guide slider within the guide groove. The combined action of the guide slider and the guide groove guides the probe rod and insulating plate. Simultaneously, the elastic force of the telescopic spring within the groove moves the arc-shaped clip away from the arc-shaped slot, allowing the probe rod, insulating plate, and probe head to be removed from the surface of the U-shaped mounting bracket for maintenance or replacement. This facilitates convenient maintenance of the probe structure, making it easier for users to remove the probe rod, insulating plate, and probe head from the U-shaped mounting bracket for inspection, maintenance, or replacement, thus enhancing its practicality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The structure of the probe structure for a battery capacity testing cabinet provided by this utility model is as follows: Figure 1 and Figure 2 As shown, the device includes a probe rod 1. An insulating plate 101 is mounted on the surface of the bottom of the probe rod 1. A U-shaped mounting bracket 102 is fitted onto the surface of the probe rod 1. A mounting stud 103 is threaded onto the surface of the U-shaped mounting bracket 102. One end of the mounting stud 103 passes through the U-shaped mounting bracket 102 and extends to the inside of the U-shaped mounting bracket 102. A voltage acquisition rod 107 is mounted on the surface of the bottom of the insulating plate 101. One end of the voltage acquisition rod 107 passes through the insulating plate 101 and the probe rod 1 and extends into the interior of the probe rod 1.

One end of the wire 106 passes through the terminal block 109 and extends into the interior of the probe rod 1. The other end of the fuse 108 is fixed to the surface of the wire 106. A probe head 105 is installed on the surface of the bottom position of the voltage acquisition rod 107. A buffer spring 104 is fitted on the surface of the voltage acquisition rod 107. One end of the buffer spring 104 is fixed to the surface of the bottom position of the insulating plate 101, and the bottom end of the buffer spring 104 is fixed to the surface of the probe head 105.

[0026] Furthermore, such as Figure 2 and Figure 4As shown, a stabilizing mounting mechanism 2 is provided on the surface of the insulating plate 101. The stabilizing mounting mechanism 2 includes a fastening stud 21, a mounting groove 22, and a stabilizing mounting assembly 23. The stabilizing mounting assembly 23 is provided on the surface of the insulating plate 101 and consists of an anti-detachment slot 231, an anti-detachment clip 232, and a stabilizing suction cup 233. The interior of the insulating plate 101 is provided with a mounting groove 22. The interior of the mounting groove 22 is provided with a stabilizing suction cup 233 for stabilizing the probe rod 1 and the insulating plate 101. The surface of the stabilizing suction cup 233 is provided with an anti-detachment clip 232. The inner wall of the insulating plate 101 is provided with an anti-detachment slot 231. The surfaces of the anti-detachment slot 231 and the anti-detachment clip 232 are engaged with each other. The surface of the insulating plate 101 is threaded with a fastening stud 21. One end of the fastening stud 21 extends into the interior of the mounting groove 22 and rotates with the surface of the stabilizing suction cup 233. The stabilizing suction cup 233 is a high-strength suction cup.

[0027] During implementation, the user tightens the fastening studs 21 on the surface of the insulating plate 101, causing the fastening studs 21 to move the stabilizing suction cup 233 inside the mounting groove 22. This causes the fastening studs 21 to move the stabilizing suction cup 233 until it contacts the inner wall of the distribution cabinet. At this time, the stabilizing suction cup 233 moves the anti-detachment clip 232 away from the inside of the anti-detachment slot 231, thereby installing the probe rod 1 at the designated position in the distribution cabinet for use, so as to achieve the function of stable installation of the probe structure.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, both the inner wall of the U-shaped mounting bracket 102 and the surface of the probe rod 1 are equipped with a maintenance and replacement mechanism 3. The maintenance and replacement mechanism 3 includes a guide slider 31, a guide groove 32, a groove 33, a telescopic spring 34, an arc-shaped clip 35, and an arc-shaped slot 36. The surface of the probe rod 1 is equipped with a guide slider 31. The inner wall of the U-shaped mounting bracket 102 has a guide groove 32, which slides and engages with the surface of the guide slider 31. The inner wall of the U-shaped mounting bracket 102 has a groove 33, and the inside of the groove 33 is equipped with an arc-shaped clip 35, which slides and engages with the inner wall of the groove 33. The surface of the probe rod 1 has an arc-shaped slot 36, which engages and engages with the surface of the arc-shaped clip 35. The inner wall of the groove 33 is equipped with a telescopic spring 34, one end of which is fixed to the surface of the arc-shaped clip 35.

[0029] During implementation, the user pulls down the insulating plate 101, causing the insulating plate 101 to move the probe rod 1. At this time, the probe rod 1 drives the guide slider 31 to slide inside the guide groove 32. Under the combined action of the guide slider 31 and the guide groove 32, the probe rod 1 and the insulating plate 101 are guided. At this time, under the elastic force of the telescopic spring 34 inside the groove 33, the arc-shaped clip 35 is moved away from the inside of the arc-shaped clip 36, thereby removing the probe rod 1, the insulating plate 101 and the probe head 105 from the surface of the U-shaped mounting bracket 102 for inspection or replacement, so as to realize the function of convenient maintenance of the probe structure.

[0030] Furthermore, such as Figure 2 and Figure 6 As shown, a precision detection mechanism 4 is provided on the inner wall of the terminal block 109 and the surface of the wire 106. The precision detection mechanism 4 includes a sealing frame 41, a sealing gasket 42, and a precision detection group 43. The precision detection group 43 is provided on the inner wall of the terminal block 109 and the surface of the wire 106. The precision detection group 43 is composed of a tension spring 431, a fixing groove 432, and a sliding block 433. The sealing frame 41 is installed on the inner wall of the terminal block 109. The sealing gasket 42 is provided inside the sealing frame 41. One end of the sealing gasket 42 extends to the outside of the sealing frame 41 and contacts the surface of the wire 106. The inner wall of the sealing frame 41 is provided with a fixing groove 432. The surface of the sealing gasket 42 is provided with a sliding block 433. The sliding block 433 slides and engages with the surface of the fixing groove 432. The inner wall of the sealing frame 41 is provided with tension springs 431 at equal intervals. One end of the tension spring 431 is fixed to the surface of the sealing gasket 42.

[0031] During implementation, the elastic force of the extension spring 431 inside the sealing frame 41 drives the sealing gasket 42 to move, causing the sealing gasket 42 to drive the sliding block 433 to slide inside the fixing groove 432. Under the combined action of the sliding block 433 and the fixing groove 432, the sealing gasket 42 is guided. Under the elastic force of the extension spring 431 inside the sealing frame 41, the sealing gasket 42 can clamp the wire 106 inside the terminal block 109, preventing the wire 106 from becoming loose during use and affecting the performance, thus achieving the function of preventing the probe structure from becoming loose.

[0032] Working principle: In use, first place the probe rod 1 in the designated position of the battery capacity testing cabinet. The user tightens the fastening stud 21 on the surface of the insulating plate 101, causing the fastening stud 21 to move the stabilizing suction cup 233 inside the mounting groove 22. This causes the fastening stud 21 to move the stabilizing suction cup 233 until it contacts the inner wall of the capacity testing cabinet. At this time, the stabilizing suction cup 233 moves the anti-detachment clip 232 away from the inside of the anti-detachment slot 231, thereby installing the probe rod 1 in the designated position of the capacity testing cabinet for use. This achieves the function of stable installation of the probe structure, making it easier to operate the probe structure when using it.

[0033] Subsequently, the user tightens the mounting studs 103 and installs the U-shaped mounting bracket 102 in the designated position. When the capacity distribution cabinet is charging and discharging the battery, if the circuit overheats due to short circuit, overcharge, reverse charging, or other phenomena during the charging and discharging process, the probe head 105 detects that the battery has short circuit, overcharge, or reverse charging. When the voltage acquisition rod 107 detects that the voltage is abnormal, the fuse 108 inside the probe rod body 1 will automatically disconnect, automatically cutting off the connection between the fuse 108 and the wire 106, thereby preventing the circuit from burning and causing a safety accident, and improving the service life of the capacity distribution cabinet.

[0034] Subsequently, under the elastic force of the extension spring 431 inside the sealing frame 41, the sealing gasket 42 moves, causing the sealing gasket 42 to drive the sliding block 433 to slide inside the fixing groove 432. Under the combined action of the sliding block 433 and the fixing groove 432, the sealing gasket 42 is guided. Under the elastic force of the extension spring 431 inside the sealing frame 41, the sealing gasket 42 can clamp the wire 106 inside the terminal block 109, preventing the wire 106 from becoming loose during use and affecting the performance. This achieves the anti-loosening function of the probe structure, thus preventing the wire 106 from becoming loose from inside the terminal block 109 during use. This also prevents the wire 106 and fuse 108 from accidentally breaking during use.

[0035] Subsequently, when the user needs to remove the probe rod 1, insulating plate 101, and probe head 105 from the surface of the U-shaped mounting bracket 102 for maintenance, the user pulls the insulating plate 101 downwards, causing the insulating plate 101 to move the probe rod 1. At this time, the probe rod 1 drives the guide slider 31 to slide inside the guide groove 32. Under the combined action of the guide slider 31 and the guide groove 32, the probe rod 1 and the insulating plate 101 are guided. At this time, under the elastic force of the telescopic spring 34 inside the groove 33, the arc-shaped clamp 35 is moved away from the arc. The probe rod 1, insulating plate 101, and probe head 105 are removed from the surface of the U-shaped mounting bracket 102 through the slot 36. This allows for the inspection or replacement of the probe rod 1, insulating plate 101, and probe head 105, facilitating easy maintenance of the probe structure. This makes it convenient for users to remove the probe rod 1, insulating plate 101, and probe head 105 from the surface of the U-shaped mounting bracket 102 for inspection, maintenance, or replacement, making the probe structure more practical and ultimately completing the battery capacity testing cabinet operation.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
