A stable battery cell device

Abstract

This invention relates to the field of battery equipment technology and discloses a stable cell device that solves the problem of positive electrode breakage during production and transportation. The device includes a housing with an inner groove inside. A tab groove is symmetrically formed at the top of the inner groove. A partition assembly is installed inside the inner groove, and electrode plates are symmetrically installed on both sides of the partition assembly. A tab is attached to the top of each electrode plate, extending through to the top of the tab groove. A protective assembly is installed at the top of the housing. In operation, the connecting plate is pressed downwards, causing the protective sleeve to enter the retraction groove, thus exposing the tab. As the protective sleeve enters the retraction groove, the inner wall of the retraction groove compresses the angled surface during downward movement, pushing the movable plate to move. This causes the support rods on both sides to move towards the tab, providing support to both sides of the tab and improving the fixing effect.

Description

Technical Field

[0001] This invention belongs to the field of battery equipment technology, specifically a device for stabilizing battery cells. Background Technology

[0002] New energy vehicle batteries consist of three parts: cells, protection circuits, and casings. Currently, new energy vehicle batteries are generally lithium-ion batteries. Lithium-ion batteries are rechargeable batteries that mainly rely on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions are inserted and extracted back and forth between the two electrodes: when charging, Li+ ions are extracted from the positive electrode and inserted into the negative electrode through the electrolyte, leaving the negative electrode in a lithium-rich state; the opposite occurs during discharging. Batteries that generally use materials containing lithium elements as electrodes are representative of modern high-performance batteries. Generally, a cell consists of electrodes, tabs, and a separator.

[0003] Because the positive electrode tab is made of aluminum strip material, and aluminum strip is easy to break, the positive electrode tab is prone to breakage during the production and transportation process, which can damage the battery cell. Summary of the Invention

[0010] Preferably, the top groove is square and its shape is adapted to the shape of the card connector, and a bottom groove is formed at the bottom end of the top groove, which is circular.

[0011] Preferably, the support assembly includes a first movable groove equidistantly formed on the inner wall of the protective sleeve. The first movable groove has an outer wall groove on the side near the outer wall of the protective sleeve and an inner wall groove on the side near the inner wall of the protective sleeve. A movable plate is movably installed inside the first movable groove. A support rod is installed on one side of the movable plate and inserted into the inner wall groove. A second spring is installed on one side of the movable plate. One end of the second spring is fixedly connected to the inner wall of the first movable groove. Limiting grooves are symmetrically formed on both sides of the first movable groove. Limiting sliders are slidably connected inside the limiting grooves and are symmetrically installed on both sides of the inner wall groove.

[0012] Preferably, a pressure rod is installed on the other side of the inner wall groove. The pressure rod is inserted into the outer wall groove and extends through to the outside of the protective sleeve. The bottom end of the pressure rod is provided with an angle.

[0013] Preferably, the warning component includes a conductive rod installed at the bottom of the connecting plate, an alarm being electrically connected to the top of the conductive rod, the alarm being fixedly connected to the top of the connecting plate, a wire being installed on one side of the alarm, a contact being electrically connected to one end of the wire, the contact being fixedly connected to the inner wall of one of the protective sleeves, the bottom end of the conductive rod being inserted into the housing groove, the housing groove being opened at the top of the housing, a partition groove being opened below the housing groove, the partition groove being opened at the top of the partition, the conductive rod being inserted into the partition groove, and a clamping component being installed at the bottom of the partition groove.

[0014] Preferably, the clamping assembly includes a first connecting groove formed on both sides of the partition groove, a second connecting groove formed at the bottom end of the first connecting groove, a second movable groove formed on one side of the second connecting groove, a through groove formed on one side of the second movable groove, one side of the through groove being in close contact with the outer wall of the diaphragm, and a movable plate being movably installed inside the second movable groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1) During operation, the housing is rotated during transportation, so that the snap-fit ​​connector aligns with the top slot. At this time, the connecting plate moves upward under the elastic force of the first spring, so that the protective sleeve is fitted onto the outside of the electrode ear, thereby improving the protection of the electrode ear and preventing the electrode ear from coming into contact with foreign objects during transportation, thus causing damage to the electrode ear.

[0018] 2) During operation, the connecting plate is pressed down to allow the protective sleeve to enter the retraction groove, thereby exposing the electrode ear. As the protective sleeve enters the retraction groove, the inner wall of the retraction groove squeezes the angle during the downward movement, thereby pushing the movable plate to move. This causes the support rods on both sides to move towards the electrode ear, providing support to both sides of the electrode ear and improving the fixing effect of the electrode ear.

[0019] 3) During operation, after the set clamping connector passes through the top groove and enters the bottom groove, the rotating plate is rotated to make the clamping connector engage with the bottom groove, thereby fixing the connecting plate. At this time, the conductive rod moves downward inside the partition groove, thereby pushing the air below the conductive rod to flow and pushing the moving plate to move, thereby making the clamping rod tension the diaphragm, thus making the diaphragm unfold and facilitating ion transfer.

[0020] 4) During operation, if the partition and diaphragm are damaged, the current will enter the conductive rod through the damaged area. The conductive rod will then form a circuit with the positive electrode through the wires and contacts. When the current flows through the alarm, the alarm will sound, allowing the user to promptly detect the risk of a short circuit in the battery, thus improving the battery's safety performance and protecting the user.

A support component 8 is installed inside the protective sleeve 7014.

[0033] The fixing unit 702 includes side plates 7021 symmetrically installed on the front and back of the connecting plate 7011. The top of the side plate 7021 is symmetrically provided with a rotating groove 7022. A snap-fit ​​rod 7023 is inserted into the rotating groove 7022.

[0034] During operation, when the housing 1 is being transported, the rotating plate 7025 is rotated so that the snap-fit ​​connector 7024 aligns with the top groove 7027. At this time, the connecting plate 7011 moves upward under the elastic force of the first spring 7013, which causes the protective sleeve 7014 to be fitted onto the outside of the electrode tab 6, thereby improving the protection of the electrode tab 6 and preventing the electrode tab 6 from coming into contact with foreign objects during transportation, thus preventing damage to the electrode tab 6.

[0035] In Embodiment 3, based on Embodiment 2, the support assembly 8 includes a first movable groove 801 equidistantly formed on the inner wall of the protective sleeve 7014. An outer wall groove 802 is formed on the side of the first movable groove 801 near the outer wall of the protective sleeve 7014, and an inner wall groove 803 is formed on the side of the first movable groove 801 near the inner wall of the protective sleeve 7014.

An angled angle 808 is opened at the bottom end of the pressure rod 807.

[0036] When the battery cell is used as the main component, the connecting plate 7011 is pressed down, causing the protective sleeve 7014 to enter the retraction groove 7016, thereby exposing the electrode tab 6. As the protective sleeve 7014 enters the retraction groove 7016, during the downward movement, the inner wall of the retraction groove 7016 squeezes the inclined angle 808, thereby pushing the movable plate 804 to move. This causes the support rods 806 on both sides to move towards the electrode tab 6, providing support to both sides of the electrode tab 6, thereby improving the fixing effect of the electrode tab 6.

[0037] In Example 4, based on Example 3, the warning component 9 includes a conductive rod 901 installed at the bottom of the connecting plate 7011.

A clamping component 10 is installed at the bottom end of the partition groove 906.

[0038] When the separator 401 and the diaphragm 402 are damaged, the current enters the conductive rod 901 through the damaged area. The conductive rod 901 then forms a circuit with the positive electrode through the wire 903 and the contact 904. At this time, the current flows through the alarm 902, causing the alarm 902 to sound an alarm. This allows the user to promptly detect the risk of a short circuit in the battery, improving the battery's safety performance and protecting the user.

[0039] In Example 5, based on Example 4, the clamping assembly 10 includes a first connecting groove 1001 opened on both sides of the partition groove 906, a second connecting groove 1002 opened at the bottom end of the first connecting groove 1001, a second movable groove 1003 opened on one side of the second connecting groove 1002, a through groove 1004 opened on one side of the second movable groove 1003, one side of the through groove 1004 is in close contact with the outer wall of the diaphragm 402, a movable plate 1005 is movably installed inside the second movable groove 1003, a clamping rod 1006 is installed on one side of the movable plate 1005, the clamping rod 1006 is inserted into the through groove 1004, and one end of the clamping rod 1006 is in contact with the outer wall of the diaphragm 402, and a third spring 1007 is installed on one side of the movable plate 1005, the third spring 1007 is in close contact with the inner wall of the second movable groove 1003;

[0040] When the battery cell is used as the main component, the connecting plate 7011 is pressed down, causing the snap-fit ​​connector 7024 to pass through the top groove 7027 and enter the bottom groove 7026. Then, the rotating plate 7025 is rotated to snap the snap-fit ​​connector 7024 into the bottom groove 7026, thereby fixing the connecting plate 7011. At this time, the conductive rod 901 moves downward inside the partition groove 906, thereby pushing the air below the conductive rod 901 to move the moving plate 1005, thereby causing the clamping rod 1006 to clamp the diaphragm 402, thereby causing the diaphragm 402 to unfold and facilitate ion transfer.
