Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery monitoring equipment, and in particular to a lead-acid battery differential pressure monitoring device. Background Technology

[0002] Lead-acid batteries are widely used in energy storage, communication, transportation and other fields. Due to differences in manufacturing process, uneven charging and discharging, and different aging levels, the individual cells in the battery pack are prone to pressure differences. Long-term pressure differences can lead to battery pack capacity decay, shortened cycle life, and even safety hazards such as thermal runaway. Existing lead-acid battery differential pressure monitoring devices use 3M adhesive for bonding and fixing. During maintenance, the entire device needs to be removed, which can easily lead to a decline in the adhesive layer's bonding performance and requires frequent replacement of the adhesive film. This results in insufficient compatibility between the fixing method and maintenance needs. Therefore, we propose a lead-acid battery differential pressure monitoring device. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a lead-acid battery differential pressure monitoring device. By setting a detachable base plate, after the base plate is fixed to the battery with 3M adhesive, the monitoring device can be removed by disassembly to complete the inspection and maintenance, without the need to peel off the film, thus avoiding the problems of adhesive layer adhesion degradation and frequent film replacement.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A lead-acid battery differential pressure monitoring device includes a monitoring mechanism, a sliding cover mechanism movably mounted at the lower end of the monitoring mechanism, and an unlocking mechanism movably mounted at the inner end of the monitoring mechanism. The sliding cover mechanism includes a base plate, with locking blocks on both the left and right sides of the upper end of the base plate. A mounting groove is opened on the rear side of the middle of the upper end of the base plate. A spring is connected to the bottom of the inner end of the mounting groove. A connecting rod is connected to the upper end of the spring. A locking rod is connected to the upper end of the connecting rod. By setting a detachable base plate, after the base plate is fixed to the battery with 3M adhesive, the monitoring device can be removed by disassembly for inspection and maintenance without peeling off the film, thus avoiding the problem of adhesive layer adhesion degradation and frequent film replacement.

[0005] Furthermore, the monitoring mechanism includes a working box, with a movable groove on the upper rear side of the working box, a locking groove in the middle of the inner end of the movable groove, mesh ports on the left and right sides of the front end of the working box, a card slot at the bottom of the lower end of the working box, and a connecting groove at the lower end of the working box. By setting the card slot for connecting the card block, the working box and the base plate can be quickly separated and accurately connected, ensuring connection stability.

[0006] Furthermore, the unlocking mechanism includes a button, the lower end of which is connected to a pressure rod. Limiting blocks are provided on the front and rear sides of the outer end of the button. By setting the limiting blocks to limit the range of motion of the adjusting locking rod, when the limiting block contacts the bottom of the movable groove, the pressure rod accurately triggers the locking rod to compress the spring and just disengage from the locking groove, thereby achieving precise and controllable locking and unlocking actions, avoiding structural damage caused by excessive or incomplete operation, and improving the reliability of device disassembly and assembly.

[0007] Furthermore, the base plate is movably nested inside the connecting groove. By setting the base plate to be movably nested inside the connecting groove, precise positioning and assembly of the base plate and the work box can be achieved, ensuring connection stability, and providing a structural basis for the rapid disassembly of the two.

[0008] Furthermore, the card block is nested within the inner end of the card slot.

[0009] Furthermore, the pressure rod is movably mounted on the inner end of the lock groove.

[0010] Furthermore, in its natural state, the locking rod is nested inside the locking groove.

[0011] Furthermore, the button is movably mounted on the inner end of the movable groove. When the button is pressed, causing the limiting block to contact the bottom of the movable groove, the pressure rod contacts the locking rod, compresses the spring, and causes the locking rod to just disengage from the locking groove.

[0012] In summary, this utility model has the following beneficial effects: 1. By setting a detachable base plate, the monitoring device can be removed for inspection and maintenance after the base plate is fixed to the battery with 3M adhesive. There is no need to peel off the film, avoiding the problem of adhesive layer adhesion degradation and frequent film replacement. By setting a slot for connecting the card block, the work box and the base plate can be quickly separated and accurately connected, ensuring connection stability. 2. By setting a limit block to limit the range of motion of the adjusting locking rod, when the limit block contacts the bottom of the movable groove, the pressure rod accurately triggers the locking rod to compress the spring and just disengage from the locking groove, realizing precise and controllable locking and unlocking actions, avoiding structural damage caused by excessive or incomplete operation, and improving the reliability of device disassembly and assembly. By setting the base plate to be movably nested in the inner end of the connecting groove, the base plate and the work box can be accurately positioned and assembled, ensuring connection stability, and providing a structural basis for the rapid disassembly of the two.

A connecting rod 205 is connected to the upper end of the spring 204. A locking rod 206 is connected to the upper end of the connecting rod 205. The locking block 202 is movably nested within the inner end of the locking groove 105. When the spring 204 is in its natural state, the locking rod 206 is nested within the inner end of the locking groove 103. By providing a detachable base plate 201, after the base plate 201 is fixed to the battery with 3M adhesive, the monitoring device can be removed for inspection and maintenance without peeling off the adhesive film, thus avoiding the problems of adhesive layer adhesion degradation and frequent film replacement.

[0018] Reference Figure 1-2As shown, the monitoring mechanism 1 includes a working box 101. The upper rear side of the working box 101 is provided with a movable groove 102. The inner middle of the movable groove 102 is provided with a locking groove 103. The front left and right sides of the working box 101 are provided with mesh ports 104. The bottom of the lower end of the working box 101 is provided with a card slot 105. The lower end of the working box 101 is provided with a connecting groove 106. By providing the card slot 105 for connecting the card block 202, the working box 101 and the base plate 201 can be quickly separated and accurately connected, ensuring the stability of the connection.

[0019] Reference Figure 1-4 As shown, the unlocking mechanism 3 includes a button 301, with a pressure rod 302 connected to the lower end of the button 301. Limiting blocks 303 are provided on the front and rear sides of the outer end of the button 301. The pressure rod 302 is movably installed in the inner end of the lock groove 103, and the button 301 is movably installed in the inner end of the movable groove 102. When the button 301 is pressed, causing the limiting block 303 to contact the bottom of the movable groove 102, the pressure rod 302 contacts the locking rod 206, compresses the spring 204, and causes the locking rod 206 to just disengage from the lock groove 103. By setting the limiting block 303 to limit the range of motion of the adjusting locking rod 206, the pressure rod 302 can accurately trigger the locking rod 206 to compress the spring 204 and just disengage from the lock groove 103 when the limiting block 303 contacts the bottom of the movable groove 102. This achieves precise and controllable locking and unlocking actions, avoids structural damage caused by excessive or insufficient operation, and improves the reliability of device disassembly and assembly.

[0021] Specific implementation process: During operation, first fix the base plate 201 to the battery surface with 3M adhesive, then insert the locking block 202 at the upper end of the base plate 201 into the locking groove 105 at the lower end of the working box 101. At the same time, the base plate 201 is movably nested in the inner end of the connecting groove 106 to achieve precise positioning. At this time, the spring 204 in the mounting groove 203 is in its natural state, and the locking rod 206 is nested in the locking groove 103 to complete the device fixation. When maintenance is required, press the button 301 to drive the pressure rod 302 to move down until the limit block 303 contacts the bottom of the movable groove 102. The pressure rod 302 pushes the locking rod 206 to compress the spring 204 and disengage from the locking groove 103. At this time, the base plate 201 can be disassembled and removed. After maintenance is completed, the reverse operation can be performed to reconnect and fix it without peeling off the 3M adhesive.
