Description

Technical Field

[0001] The utility model belongs to the technical field of battery elements, and in particular relates to a pressure-resistant valve-controlled sealed lead-acid battery. Background Art

[0002] The pressure-resistant, valve-regulated, sealed lead-acid battery is a backup energy storage device designed to maintain both an airtight and liquid-tight seal. When internal pressure exceeds a predetermined value, a safety valve automatically opens to release gas and then automatically closes to prevent air from entering the battery. This design makes the battery extremely safe in normal use and suitable for a wide range of applications.

[0003] In the above, the battery will generate heat accumulation when working, and when the battery is squeezed by external force, the internal heat escape rate is significantly accelerated, causing the temperature to rise sharply, impacting the safety valve at the top, which causes the safety valve to bear excessive pressure and affect the sealing. Therefore, it is necessary to reduce the external force on the battery. Utility Model Content

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figure 1-2 , is the first embodiment of the present utility model, which provides a pressure-resistant valve-regulated sealed lead-acid battery, comprising:

[0027] The battery body 100 is provided with a buffer mechanism 200 , which is provided with a pressure-resistant mechanism 300 , and an outer frame 403 is provided on the side of the battery body 100 ;

[0028] In addition, the pressure-resistant mechanism 300 includes a support frame 301, the side of the support frame 301 is fixedly connected to the battery body 100, the top of the support frame 301 is rotatably sleeved with a connecting column 302, the end face of the connecting column 302 is fixedly connected to a threaded rod 304, the threaded rod 304 is engaged with a transmission tooth 305, the transmission tooth 305 is cooperated with a clamping claw 311, and the outer surface of the connecting column 302 is fixedly connected to a shift rod 303.

[0029] Specifically, the fixed connection between the support frame 301 and the battery body 100 allows the pressure-resistant mechanism 300 to directly clamp the battery body 100, helping the battery body 100 to maintain relative stability, reducing the escape velocity of high-temperature gas during operation, and indirectly ensuring the sealing effect. The engagement of the threaded rod 304 with the transmission tooth 305 allows the clamping claw 311 to clamp symmetrically, and the battery body 100 can maintain opposite balance and remain relatively still. The fixed connection between the lever 303 and the connecting column 302 allows the threaded rod 304 to be actively rotated and adjusted.

[0030] Furthermore, a shaft rod 306 is fixedly connected to the lower surface of the transmission gear 305 , a side rod 307 is inserted into the bottom of the shaft rod 306 , and a ball bearing 308 is slidably connected to the end surface of the side rod 307 .

[0031] Preferably, the fixed connection between the shaft 306 and the transmission tooth 305 makes the rotation of the transmission tooth 305 more uniform, while also ensuring the long-term clamping of the clamping jaw 311. The sliding connection between the side rod 307 and the ball bearing 308 can ensure the concentricity of the shaft 306 and improve the rotation stability of the shaft 306.

[0032] During use, first, the support frame 301 is fixedly connected to the battery body 100, then the connecting column 302 is fixedly mounted on the top of the support frame 301 and rotated, and then the threaded rod 304 is fixedly installed on the connecting column 302. After that, the shaft 306 is fixedly mounted on the bottom of the transmission gear 305, and the side rod 307 is inserted into the bottom of the shaft 306, so that the shaft 306 and the ball bearing 308 are in sliding contact.

[0033] In summary, through the fixed connection between the support frame 301 and the battery body 100, the pressure-resistant mechanism 300 can directly clamp the battery body 100, helping the battery body 100 to maintain relative stability, reducing the escape velocity of high-temperature gas during operation, and indirectly ensuring the sealing effect. The engagement of the threaded rod 304 and the transmission tooth 305 allows the clamping claws 311 to clamp symmetrically, and the battery body 100 can maintain opposite balance and remain relatively still. The fixed connection between the lever 303 and the connecting column 302 allows the threaded rod 304 to be actively rotated and adjusted.

[0034] Example 2

[0035] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving a symmetrical buffering effect.

[0036] Specifically, a receiving tube 309 is inserted into the lower surface of the ball bearing 308 , and the receiving tube 309 is fixedly connected to the support frame 301 .

[0037] Furthermore, the connection between the receiving tube 309 and the ball bearing 308 allows the ball bearing 308 to be stably placed, thereby ensuring the stable rotation of the shaft 306 .

[0038] Preferably, a swing arm 310 is fixedly sleeved on the outer surface of the shaft 306 , and the swing arm 310 is rotatably connected to a clamping claw 311 through a pin shaft, and the clamping claw 311 is clamped with the side surface of the battery body 100 .

[0039] The swing arm 310 is rotatably connected to the clamping jaw 311 so that the clamping jaw 311 and the battery body 100 can be adaptively clamped, and the battery body 100 can remain stable.

[0040] Then, the buffer mechanism 200 includes a spring rod 202 , one end of which is fixedly connected to the battery body 100 , and the other end of the spring rod 202 is plugged with a collar 203 , and the side surface of the collar 203 is fixedly connected to the outer frame 403 .

[0041] In the above, the coordination of the spring rod 202 and the outer frame 403 makes the elastic buffering effect of the spring rod 202 on the battery body 100 more balanced, and the outer frame 403 can also limit the spring rod 202 to ensure the relative stability of the spring rod 202 itself.

[0042] During use, first, the receiving tube 309 and the ball bearing 308 are plugged and installed, then the swing arm 310 is fixedly sleeved on the outer surface of the shaft 306, the clamping jaw 311 and the swing arm 310 are rotated and installed through the pin shaft, and then the clamping jaw 311 is snapped and fitted with the battery body 100, and then the ring 203 and the spring rod 202 are plugged and installed, and the outer frame 403 and the ring 203 are fixedly installed to provide stable buffering for the spring rod 202.

[0043] In summary, through the coordinated arrangement of the spring rod 202 and the outer frame 403, the elastic buffering effect of the spring rod 202 on the battery body 100 is more balanced, and the outer frame 403 can also limit the spring rod 202 to ensure the relative stability of the spring rod 202 itself, while reducing the shaking of the battery body 100, and the movement speed of the internal high-temperature gas is relatively slowed down, thereby reducing the pressure on the top of the battery body 100.

[0047] Furthermore, the symmetrical arrangement of the spring rods 202 provides a balanced elastic buffering effect on the side surfaces of the square frame 201 , thereby preventing the battery body 100 from being bumped due to displacement of the square frame 201 .

[0048] Among them, the battery body 100 is equipped with a sealing mechanism 400, and a column is fixedly connected to the top of the battery body 100. The sealing mechanism 400 includes a first sealing tooth 401, and the outer surface of the column is fixedly sleeved with a first sealing tooth 401 and a second sealing tooth 402, and the first sealing tooth 401 and the second sealing tooth 402 are engaged.

[0049] Preferably, the meshing of the first sealing teeth 401 and the second sealing teeth 402 improves the sealing effect of the top of the battery body 400 , which is beneficial to maintaining the dynamic balance of the internal gas.

[0050] When in use, firstly, the first sealing teeth 401 and the second sealing teeth 402 are fixedly sleeved on the outer surface of the battery body 100 , and then a plurality of spring rods 202 are symmetrically arranged on the surface of the square frame 201 .

[0051] In summary, the symmetrical arrangement of the spring rods 202 provides a balanced elastic buffering effect on the side surfaces of the square frame 201 , thereby preventing the battery body 100 from being bumped due to displacement of the square frame 201 .
