Description

Technical Field

[0001] This invention relates to the field of batteries, specifically to a high-safety lithium-ion battery equipped with an internal pressure control component. Background Technology

[0002] Lithium-ion batteries store energy by inserting and deintercalating lithium ions between the positive and negative electrodes. They are primarily composed of positive and negative electrode materials, electrolyte, and a separator, and possess outstanding characteristics such as high energy density and no memory effect. Some server racks are equipped with small lithium batteries to provide emergency power in the event of a sudden power outage, ensuring the rack's normal operation for a short period.

[0003] However, when assembling existing lithium batteries inside the cabinet, it is necessary to weld battery mounting brackets onto the cabinet in advance, and then use the welded battery brackets to fix the lithium batteries. The installation process is quite cumbersome, which not only greatly increases the difficulty of on-site installation and construction, but also prolongs the overall installation time, resulting in poor installation convenience and low efficiency of lithium batteries. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a high-safety lithium-ion battery with an internal pressure control component.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-safety lithium-ion battery with an internal pressure control component, comprising a lithium battery, a load-bearing bracket disposed at the rear of the lithium battery, the load-bearing bracket being adapted to the frame of a cabinet door, a main mounting bracket fixedly mounted on the upper end of the load-bearing bracket, a secondary mounting bracket disposed on the side of the main mounting bracket, and two arc-shaped clamps symmetrically fixedly mounted on the opposing surfaces of the vertical sections of the main mounting bracket and the secondary mounting bracket, the arc-shaped clamps being adapted to the arc surface of the outer shell of the cooling fan on the cabinet door. Two concave slot seats are symmetrically fixedly installed at the front end of the vertical section of the main mounting bracket and the front end of the vertical section of the auxiliary mounting bracket. The concave slot seats are adapted to the outer edge of the heat dissipation fan shell on the cabinet door. A connector is provided at the lower end of the load-bearing bracket. Four corner blocks are connected to the end of the connector. The corner blocks are attached to the lower corner of the lithium battery. A pressure control component is installed at the upper end of the lithium battery. A concave positioning frame is fixedly installed at the lower end of the auxiliary mounting bracket. The concave positioning frame is attached to the upper end of the lithium battery. A locking component is provided between the auxiliary mounting bracket and the main mounting bracket.

[0006] Preferably, the connector includes a hanger fixedly installed at the lower end of the load-bearing bracket, an X-shaped frame fixedly installed at the end of the hanger, and the corner block fixed to the end of the X-shaped frame.

[0007] Preferably, the locking component includes two fixed hooks symmetrically and rotatably mounted on the upper end face of the horizontal section of the sub-mounting bracket. The end of the horizontal section of the sub-mounting bracket is inserted into the horizontal section of the main mounting bracket. The front and rear ends of the horizontal section of the main mounting bracket both extend with arc-shaped tongues. One end of each fixed hook is provided with an arc-shaped groove, and the arc-shaped tongue is inserted into the interior of the arc-shaped groove.

[0008] Preferably, a connecting shaft is rotatably mounted through the other end of the fixed hook, a shaft lug is fixedly mounted in the middle of the connecting shaft, the lower end of the shaft lug is fixed to the sub-mounting bracket, a shaft cap is fixedly mounted at both ends of the connecting shaft, a torsion spring is provided between the shaft cap and the fixed hook, the connecting shaft passes through the inside of the torsion spring, a handle is provided between the two fixed hooks, and the center of the arc-shaped tongue is collinear with the center of the connecting shaft.

[0009] Preferably, the front and rear ends of the horizontal section of the secondary mounting bracket are extended with guide ridges, and two symmetrical grooves are opened inside the horizontal section of the main mounting bracket, with the guide ridges slidably installed inside the grooves.

[0010] Preferably, the pressure control component includes a right-angle tube that is installed through the upper end of the lithium battery. The lower end of the right-angle tube has a through-hole for air intake, which is connected to the lithium battery. A control cap is pressed onto the air intake and is elastically connected to the right-angle tube. A protective cap is inserted into the front end of the right-angle tube. The front end of the protective cap has multiple through-holes for air outlet, which are cone-shaped. A filter screen is installed on the inner surface of the front end of the right-angle tube.

[0011] Preferably, a rubber sleeve is fixedly installed on the outer surface of the front end of the right-angle tube. The rubber sleeve fits against the inner surface of the protective cap. A rubber ridge extends from the outer surface of the rubber sleeve. The cross-sectional shape of the rubber ridge is triangular. A triangular groove is opened on the inner surface of the protective cap. The rubber ridge fits into the triangular groove.

[0012] Preferably, the upper end of the control cap extends coaxially with a cap rod, a carrier sleeve is slidably mounted on the outer surface of the cap rod, the carrier sleeve is fixed to the inner wall of the right-angle tube, and a control spring is wound around the outer side of the cap rod, with the two ends of the control spring being fixed to the carrier sleeve and the control cap, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Attach the load-bearing bracket to the frame of the cabinet door. Then place the lithium battery on the corner bracket. Next, move the secondary mounting bracket toward the main mounting bracket so that the curved clamps on the secondary and main mounting brackets are flush against the curved surface of the cooling fan housing on the cabinet door, and the concave slot is engaged with the edge of the cooling fan housing. At the same time, the concave positioning bracket on the secondary mounting bracket is engaged with the upper end of the lithium battery. Then, lock the secondary and main mounting brackets with the locking mechanism. This allows the lithium battery to be installed in the cabinet. The process utilizes the existing frame and cooling fan of the cabinet as fulcrums to complete the installation of the lithium battery, eliminating the need for additional welding of the battery rack. This effectively improves installation efficiency and convenience.

[0014] 2. When the internal electrolyte of a lithium battery produces gas due to high temperature or other factors, causing the internal pressure of the battery to rise, the gas will be pushed up by the control cap pressed by the control spring under the pressure, allowing the vent to open and enter the right-angle tube. The gas will then be discharged from the vent on the protective cap, thereby reducing the internal pressure of the lithium battery and preventing safety hazards caused by excessive internal pressure. This improves the safety of the lithium battery. At the same time, the conical shape of the vent prevents a large amount of outside air from entering the right-angle tube and causing backflow. In addition, the filter can also intercept dust and other impurities in the air, preventing them from entering the lithium battery and causing safety hazards, thus further ensuring the safety of the lithium battery.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: such as Figures 1-8The high-safety lithium-ion battery with an internal pressure control component is shown. It includes a lithium battery 1, with a load-bearing bracket 6 positioned behind the battery 1. The load-bearing bracket 6 is adapted to the frame 34 of the cabinet door 35, ensuring smooth engagement between the bracket 6 and the frame 34 to support the lithium battery 1. A main mounting bracket 8 is fixedly installed on the upper end of the load-bearing bracket 6, and a secondary mounting bracket 7 is positioned to the side of the main mounting bracket 8. Both the main mounting bracket 8 and the secondary mounting bracket 7 serve a load-bearing function. Two arc-shaped clamps 17 are symmetrically fixedly installed on the opposite surfaces of the vertical sections of the main mounting bracket 8 and the secondary mounting bracket 7. The arc-shaped clamps 17 are fixed to the cabinet door. The curved surface of the cooling fan 33 on the door 35 is adapted to the curved surface of the outer shell, ensuring that the curved clamp 17 fully fits the curved surface of the cooling fan 33's outer shell. Two concave slots 18 are symmetrically fixedly installed at the front ends of the vertical sections of the main mounting bracket 8 and the secondary mounting bracket 7. The concave slots 18 are adapted to the edges of the cooling fan 33's outer shell on the cabinet door 35, ensuring that the concave slots 18 smoothly engage with the edges of the cooling fan 33's outer shell. The cooperation between the curved clamp 17, the concave slots 18, and the cooling fan 33 ensures that the load-bearing bracket 6 will not separate from the frame 34. A connecting... The connector has four corner supports 2 at its ends. The corner supports 2 are attached to the lower corners of the lithium battery 1 and serve to support and limit the lithium battery 1. A pressure control component is installed on the upper end of the lithium battery 1. A concave positioning bracket 3 is fixedly installed on the lower end of the secondary mounting bracket 7. The concave positioning bracket 3 is attached to the upper end of the lithium battery 1, ensuring that the lithium battery 1 is always positioned on the corner supports 2. A locking component is provided between the secondary mounting bracket 7 and the main mounting bracket 8 to lock the load-bearing bracket 6 onto the frame 34 of the cabinet door 35. Then, the lithium battery 1 is placed on the corner supports 2, and the secondary mounting bracket 7 is then moved toward the main mounting bracket 8. The arc-shaped clamps 17 on the secondary mounting bracket 7 and the main mounting bracket 8 can be tightly attached to the arc surface of the outer shell of the cooling fan 33 on the cabinet door 35, and the concave slot seat 18 can be engaged with the edge of the outer shell of the cooling fan 33. At the same time, the concave positioning bracket 3 on the secondary mounting bracket 7 is attached to the upper end of the lithium battery 1. Then, the secondary mounting bracket 7 and the main mounting bracket 8 are locked by the locking device, so that the lithium battery 1 can be installed in the cabinet. The process can be completed by using the original frame 34 and the cooling fan 33 on the cabinet as fulcrums, without the need to weld the battery frame for installation, thus effectively improving the installation efficiency and convenience.

[0019] The connector includes a hanger 22 fixedly installed at the lower end of the load-bearing bracket 6, an X-shaped bracket 21 fixedly installed at the end of the hanger 22, and corner bracket 2 fixed to the end of the X-shaped bracket 21. The hanger 22 and the X-shaped bracket 21 serve to fix the corner bracket 2 and the load-bearing bracket 6 together.

[0020] The locking mechanism includes two fixed hooks 14 symmetrically and rotatably mounted on the upper surface of the horizontal section of the sub-mounting bracket 7. The end of the horizontal section of the sub-mounting bracket 7 is inserted into the horizontal section of the main mounting bracket 8. The front and rear ends of the horizontal section of the main mounting bracket 8 are extended with arc-shaped tongues 16. The cooperation between the fixed hooks 14 and the arc-shaped tongues 16 can lock the sub-mounting bracket 7 and the main mounting bracket 8. One end of the fixed hook 14 is provided with an arc-shaped groove 15. The arc-shaped tongue 16 is inserted into the interior of the arc-shaped groove 15. The arc-shaped groove 15 serves to cooperate with the arc-shaped tongue 16.

[0021] The other end of the fixed hook 14 is rotatably mounted with a connecting shaft 10, which allows the fixed hook 14 to rotate. A shaft lug 9 is fixedly mounted in the middle of the connecting shaft 10, which fixes the connecting shaft 10. The lower end of the shaft lug 9 is fixed to the sub-mounting bracket 7. Both ends of the connecting shaft 10 are fixedly mounted with shaft caps 12. A torsion spring 11 is provided between the shaft cap 12 and the fixed hook 14. The shaft cap 12 connects to the torsion spring 11. The connecting shaft 10 passes through the inside of the torsion spring 11, which resets the fixed hook 14 after rotation. A handle 13 is provided between the two fixed hooks 14, which facilitates the movement of the fixed hook 14. The center of the arc tongue 16 is collinear with the center of the connecting shaft 10, ensuring that the arc groove 15 on the fixed hook 14 smoothly engages with the arc tongue 16 after the fixed hook 14 rotates.

[0022] The horizontal section of the auxiliary mounting bracket 7 has guide ribs 19 extending from both the front and rear ends. The horizontal section of the main mounting bracket 8 has two symmetrical grooves 20. The cooperation between the guide ribs 19 and the grooves 20 serves to guide the auxiliary mounting bracket 7 and the main mounting bracket 8. The guide ribs 19 are slidably installed inside the grooves 20.

[0023] The pressure control component includes a right-angle tube 4 that penetrates the upper end of the lithium battery 1. A vent 27 is provided at the lower end of the right-angle tube 4, serving to supply and discharge gas. The vent 27 is connected to the lithium battery 1, and a control cap 26 is pressed onto the vent 27 to seal it. The control cap 26 is elastically connected to the right-angle tube 4, and a protective cap 5 is inserted into the front end of the right-angle tube 4. When the internal electrolyte of the lithium battery 1 generates gas due to high temperature or other factors, causing the internal pressure of the lithium battery 1 to rise, the gas will be pushed up by the control cap 26, which is pressed by the control spring 25, under the action of pressure, allowing the vent 27 to open. Gas can enter the right-angle tube 4 and be discharged from the vent 29 on the protective cap 5, thereby reducing the internal pressure of the lithium battery 1 and avoiding safety hazards caused by excessive internal pressure, thus improving the safety of the lithium battery 1. The front end of the protective cap 5 has multiple vents 29, which are cone-shaped. A filter 28 is installed on the inner surface of the front end of the right-angle tube 4. Due to the cone shape of the vents 29, a large amount of outside air can be prevented from entering the right-angle tube 4 and causing backflow. In addition, the filter 28 can also intercept dust and other impurities in the air to prevent them from entering the lithium battery 1 and causing safety hazards, thereby further ensuring the safety of the lithium battery 1.

[0024] A rubber sleeve 30 is fixedly installed on the outer surface of the front end of the right-angle tube 4. The rubber sleeve 30 fits against the inner surface of the protective cap 5. The outer surface of the rubber sleeve 30 extends with rubber protrusions 31. The rubber sleeve 30 can increase the friction force so that the protective cap 5 will not fall off when it is inserted into the right-angle tube 4. The cross-sectional shape of the rubber protrusions 31 is triangular. A triangular groove 32 is opened on the inner surface of the protective cap 5. The rubber protrusions 31 fit into the triangular groove 32. The cooperation between the rubber protrusions 31 and the triangular groove 32 can improve the fixing force to further prevent the protective cap 5 from falling off.

[0025] A cap rod 24 extends coaxially from the upper end of the control cap 26. A carrier sleeve 23 is slidably mounted on the outer surface of the cap rod 24. The engagement between the cap rod 24 and the carrier sleeve 23 guides the control cap 26. The carrier sleeve 23 is fixed to the inner wall of the right-angle tube 4. A control spring 25 is wound around the outer side of the cap rod 24. The two ends of the control spring 25 are fixed to the carrier sleeve 23 and the control cap 26, respectively. The control spring 25 can press the control cap 26 so that the vent 27 remains normally closed when the internal pressure of the lithium battery 1 is low.

[0026] In use, the load-bearing bracket 6 is engaged with the frame 34 of the cabinet door 35. Then, the lithium battery 1 is placed on the corner bracket 2. Next, the handle 13 is turned to tilt the fixing hook 14 upwards, and the secondary mounting bracket 7 is moved towards the main mounting bracket 8. This allows the arc-shaped clamps 17 on the secondary mounting bracket 7 and the main mounting bracket 8 to fit tightly against the arc surface of the cooling fan 33 on the cabinet door 35, and the concave slot seat 18 to engage with the edge of the cooling fan 33. At the same time, the concave positioning bracket 3 on the secondary mounting bracket 7 is engaged with the upper end of the lithium battery 1. Then, the handle 13 is released, allowing the fixing hook 14 to reset under the action of the torsion spring 11 and engage with the arc-shaped tongue 16, thereby securing the secondary mounting bracket 7 and the main mounting bracket 8. The mounting bracket 8 is locked, allowing the lithium battery 1 to be installed inside the cabinet. The circuitry between the lithium battery 1 and the cabinet is then connected via wiring, enabling the cabinet to operate even during power outages. During this process, if the internal electrolyte of the lithium battery 1 produces gas due to high temperatures or other factors, causing an increase in internal pressure, the gas will be pushed up by the control cap 26, which is pressed by the control spring 25. This opens the vent 27, allowing the gas to enter the right-angle tube 4 and exit through the vent 29 on the protective cap 5. This reduces the internal pressure of the lithium battery 1, preventing safety hazards caused by excessive internal pressure and improving the safety of the lithium battery 1.
