Description

Technical Field

[0001] This invention relates to the field of battery assembly housing technology, specifically to a modular power battery assembly housing with integrated pressure warning. Background Technology

[0002] The battery casing, also known as the battery case, is the external container structure that directly wraps around and encapsulates the core electrochemical components inside the battery. It is the core packaging and safety component of the battery and is widely used in various electronic products.

[0003] For example, patent CN221687705U discloses a battery pack casing, relating to the field of battery technology. It includes a casing body with internal cables and an adjustment device. The adjustment device includes a slide rail fixedly connected to the casing body. An adjustment block is slidably connected inside the slide rail, and a connecting block is fixedly connected to the surface of the adjustment block. A bolt is threaded into the internal part of the connecting block, abutting against the slide rail. A control frame is fixedly connected to the surface of the adjustment block. By using the adjustment device, the usable space inside the battery pack casing can be changed, thus adapting the battery size to the internal space of the battery pack casing. This avoids insufficient tightness between the battery and the battery pack casing, preventing the battery from easily shaking inside the battery pack casing, thereby improving the performance of the battery pack casing.

[0004] Most of the aforementioned existing technologies improve the overall structure. However, many existing battery pack casings lack real-time pressure monitoring during use, making it impossible to repair batteries in a timely manner when they malfunction. Furthermore, the assembly process of many battery pack casings is quite cumbersome, making it difficult to quickly open the casing when timely repairs of the internal battery pack are needed, thus reducing repair efficiency. Moreover, in the event of a battery explosion inside the casing, due to its closed structure, the high pressure inside cannot be released in time, and the battery may be burning during the explosion, making it impossible to extinguish the fire from inside the casing. Summary of the Invention

[0005] The purpose of this invention is to provide a modular power battery assembly housing with integrated pressure warning, in order to solve the problems mentioned in the background art. Many existing battery assembly housings lack real-time pressure monitoring functions during use, making it impossible to repair the battery in time when it malfunctions. Furthermore, the assembly process of many battery pack housings is cumbersome, making it difficult to quickly open the housing when timely repair of the internal battery pack is needed, thus reducing repair efficiency. Moreover, when a battery explosion occurs inside the housing, the high pressure inside cannot be released in time due to its closed structure, and the battery may be burning in the event of an explosion, making it impossible to extinguish the fire from inside the housing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular power battery assembly housing with integrated pressure warning, comprising an outer shell, a gasket fixedly connected inside the outer shell, a battery body placed on top of the gasket, a wire through hole provided on the surface of the outer shell, and several sets of partitions fixedly connected inside the outer shell; an auxiliary component is provided inside the outer shell, which is used to fix the battery body and monitor the pressure value of the battery body in real time; a locking component is provided outside the outer shell, which facilitates the maintenance of the internal components of the outer shell; and a protective component is provided on the left side of the outer shell, which is used to enhance the safety of the housing during use.

[0007] Furthermore, the auxiliary component includes a connecting plate that is slidably connected inside the partition. A stabilizing plate is fixedly connected to the side of the connecting plate, and a sliding rod that is slidably connected to the outer shell is fixedly connected to the bottom of the stabilizing plate. A first nut is threaded onto the surface of the sliding rod. An installation rod is fixedly connected to the side of the partition, and a clamping plate is slidably connected to the surface of the installation rod. A second nut is threaded onto the surface of the installation rod.

[0008] Furthermore, the auxiliary component also includes a pressure sensor, which is connected to the side of the clamp and the detection head is in contact with the battery body. A warning controller is fixedly connected to the surface of the outer casing. A buzzer is fixedly connected to the outer casing on one side of the warning controller, and an indicator light is fixedly connected to the outer casing on the other side of the buzzer.

[0009] Furthermore, the engaging assembly includes a slot disposed on the top of the housing, an engaging strip slidably connected inside the slot, a top cover fixedly connected to the top of the engaging strip, a vertical rod fixedly connected to the left side of the housing, a transmission plate slidably connected to the surface of the vertical rod, a push rod fixedly connected to one side of the transmission plate, and a fixing block slidably connected to the side of the housing.

[0010] Furthermore, the engaging assembly also includes side strips, which are fixedly connected to both ends of the upper cover, and a pressure plate is fixedly connected to the top of the transmission plate.

[0011] Furthermore, the protective component includes a pressure relief port, which is fixedly connected to both sides of the outer shell. A venting disc is fixedly connected inside the pressure relief port. A fireproof mesh is fixed inside the pressure relief port on one side of the venting disc. A sealing cap is rotatably connected to the top of the pressure relief port. A torsion spring is provided at the rotatable connection between the sealing cap and the pressure relief port.

[0012] Furthermore, the protective component also includes a flame retardant encapsulation block, which is fixedly connected to the inner wall of the housing, and a coolant pipe is fixedly connected to the bottom of the housing.

[0013] Furthermore, the stabilizing plate has a "U" shaped structure and is attached to the battery body. The clamping plate has heat dissipation holes inside, and the outer shell is made of high-strength aluminum alloy.

[0014] Furthermore, the slot and the engaging strip are configured as an "X" shape, the engaging strip is made of rubber, and the contact area between the top cover and the outer shell is provided with a rubber ring.

[0015] Furthermore, the end of the pressure relief port and the sealing cover are both inclined, the fireproof mesh is arranged in three sets at equal intervals, and the explosion relief plate is an arched shape protruding outward.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This modular power battery assembly housing with integrated pressure warning features auxiliary components. These components, through adjustable clamps and stabilizing plates, can secure battery bodies of different sizes, preventing them from shaking inside the housing. Furthermore, a pressure sensor can detect the pressure value of the battery body, and an alarm will sound immediately when an abnormal pressure occurs, facilitating timely maintenance by workers.

[0017] Furthermore, by setting up a locking assembly, the top cover is locked to the outer shell by a locking strip, making it easy to open the outer shell for timely internal inspection. During installation, by pulling down the transmission plate, the fixing block can be moved to the locking strip, thereby fixing the top cover to the top of the outer shell. When the transmission plate descends, the side strip can also be pressed down by the pressure plate, so that the top cover can fit more tightly to the outer shell.

[0018] Furthermore, by setting up protective components, when the battery pack inside the casing explodes, the high pressure inside the casing will rupture the explosion relief plate and open the sealing cover to release the high-pressure gas, preventing the casing from being in a high-pressure state and causing the casing to crack. The flame arrestor mesh can block the flame layer by layer and eventually extinguish it. The flame retardant inside the flame retardant block will be sprayed out due to the explosion, which will help extinguish the flame inside the casing. Attached Figure Description

[0021] 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.

[0022] Example 1: Please refer to Figures 1-8This invention provides the following technical solution: a modular power battery assembly housing with integrated pressure warning. To address the problem that many existing battery assembly housings lack real-time pressure monitoring during use, making it impossible to perform immediate repairs when a battery malfunctions, the invention discloses a housing comprising: an outer shell 1; a gasket 2 fixedly connected inside the outer shell 1; a battery body 3 placed on top of the gasket 2; a wire-passing hole 4 on the surface of the outer shell 1; several sets of partitions 5 fixedly connected inside the outer shell 1; and an auxiliary component inside the outer shell 1. This auxiliary component is used to fix the battery body 3 while simultaneously monitoring the pressure value of the battery body 3 in real time. The auxiliary component includes a connecting plate 7 slidably connected inside the partitions 5. A stabilizing plate 6 is fixedly connected to the side of the connecting plate 7. A sliding rod 8, which is slidably connected to the bottom of the stabilizing plate 6, is fixedly connected to the bottom of the outer casing 1. A first nut 9 is threaded onto the surface of the sliding rod 8. An mounting rod 10 is fixedly connected to the side of the partition plate 5. A clamping plate 12 is slidably connected to the surface of the mounting rod 10. A second nut 11 is threaded onto the surface of the mounting rod 10. The auxiliary components also include a pressure sensor 13, which is connected to the side of the clamping plate 12 and has its detection head in contact with the battery body 3. A warning controller 14 is fixedly connected to the surface of the outer casing 1. A buzzer 15, which is fixedly connected to the outer casing 1, is located on one side of the warning controller 14. An indicator light 16, which is fixedly connected to the outer casing 1, is located on one side of the buzzer 15. The stabilizing plate 6 has a "U" shaped structure and is connected to the outer casing 1. The battery bodies 3 are fitted together, and the clamping plates 12 have internal heat dissipation holes. The outer casing 1 is made of high-strength aluminum alloy. When installing the battery pack, the battery pack is placed on the pads 2 inside the outer casing 1 and leveled. Then, the two clamping plates 12 are slid along the connecting plate 7 to move to the position where they fit against the battery pack, thus limiting and fixing the two battery packs. At the same time, to prevent the battery pack from moving to both ends, the sliding rod 8 can be controlled to slide towards the battery pack. The U-shaped stabilizing plate 6 will eventually fit against the battery pack, thus fixing both ends of the battery pack. Under the action of the stabilizing plate 6 and the clamping plates 12, the battery pack can be fixed in a fixed state, preventing it from shaking and damaging the internal components, and ensuring stability. Plate 6 and clamping plate 12 are designed to be movable, allowing for adjustment of their fixed positions according to battery packs of different sizes. The pad 2 supports the battery body 3, preventing moisture from getting into the bottom of the battery body 3. By setting pressure sensor 13, the surface pressure generated by the battery module during operation due to heat expansion, internal short circuits, and other faults is monitored in real time. The pressure signal is converted into an electrical signal and transmitted to the early warning controller 14. The early warning controller 14 processes and analyzes the signal. When the pressure value of any sensor reaches or exceeds the preset value, an early warning command is immediately triggered. Indicator light 16 switches to a red flashing state, and buzzer 15 works synchronously with indicator light 16, emitting a continuous buzzing alarm to remind staff to perform timely maintenance.

[0023] Example 2: Based on Example 1, to address the problem that the assembly process of the outer casing 1 of many battery packs is cumbersome, and that it is difficult to quickly open the outer casing 1 when timely maintenance of the internal battery pack is required, thus reducing maintenance efficiency, a locking assembly is also disclosed. Its specific structure is as follows: A locking assembly is provided on the outside of the outer casing 1, which facilitates maintenance of the internal components of the outer casing 1. A protective assembly is provided on the left side of the outer casing 1 to enhance the safety of the casing during use. The locking assembly includes a slot 17, which is located on the top of the outer casing 1. A locking strip 18 is slidably connected inside the slot 17, and a top cover 19 is fixedly connected to the top of the locking strip 18. A vertical rod 21 is fixedly connected to the left side of the outer casing 1, and a transmission plate 22 is slidably connected to the surface of the vertical rod 21. A push rod 23 is fixedly connected to one side of the transmission plate 22. A fixing block 24 is slidably connected to the side of the outer casing 1. The locking assembly also includes side strips 20, which are fixedly connected to both ends of the top cover 19. A pressure plate 32 is fixedly connected to the top of the cover 19. The slot 17 and the engaging strip 18 are set in an "X" shape. The engaging strip 18 is made of rubber. A rubber ring is provided at the contact part between the cover 19 and the outer shell 1. By setting the engaging assembly, since the cover 19 is engaged with the slot 17 through the engaging strip 18, when removing the cover 19, it is only necessary to pull the engaging strip 18 out of the slot 17. During installation, after engaging the engaging strip 18 with the slot 17, the transmission plate 22 slides down along the vertical rod 21. At this time, the push rod 23 will also descend and push the inclined surface of the fixing block 24. Under the pressure of the inclined surface, the fixing block 24 will slide along the outer shell 1 to the side and finally fit with the locking strip 18, fixing it inside the slot 17, thereby fixing the top cover 19. By setting the pressure plate 32, during the descent of the transmission plate 22, the pressure plate 32 will be driven to descend synchronously. At this time, the pressure plate 32 will press down on the side strip 20, making the top cover 19 more firmly attached to the top of the outer shell 1.

[0024] Example 3: Based on Example 1, to address the problem that in many battery packs, when a battery explodes inside the casing 1, the high pressure inside cannot be released in time due to its closed structure, and the battery may be burning during the explosion, making it impossible to extinguish the fire from inside the casing, a protective component is also disclosed. Its specific structure is as follows: A protective component is provided on the left side of the casing 1 to enhance the safety of the casing during use. The protective component includes a pressure relief port 25, which is fixedly connected to both sides of the casing 1. A venting plate 26 is fixedly connected inside the pressure relief port 25. A fireproof mesh 27 is fixedly installed inside the pressure relief port 25 on one side of the venting plate 26. A sealing cap 28 is rotatably connected to the top of the pressure relief port 25. A torsion spring 29 is provided at the rotatable connection between the sealing cap 28 and the pressure relief port 25. The protective component also includes a flame retardant encapsulation block 30, which is fixedly connected to the inner wall of the casing 1. A coolant pipe 31 is fixedly connected to the bottom of the casing 1. Both the pressure relief port 25 and the sealing cover 28 are inclined. Three sets of fireproof mesh 27 are equidistantly arranged. The explosion relief plate 26 is an arched design that protrudes outward. By setting up protective components, when an explosion occurs inside the outer shell 1, the high pressure generated will immediately impact the explosion relief plate 26. The explosion relief plate 26 will rupture due to the impact, and the high pressure gas will be discharged instantly from the pressure relief port 25 and impact the sealing cover 28. Since the sealing cover 28 is set in an inclined shape, it is easier to be opened by the impact, so as to discharge the high pressure gas and avoid the problem of the outer shell 1 being in a high pressure state and causing the outer shell 1 to explode. By setting up fireproof mesh 27, the fireproof mesh 27 can block the fire layer by layer. The flames generated by the explosion will be extinguished by the fireproof mesh 27, preventing the fire from being discharged from the pressure relief port 25 and igniting other objects. When the explosion occurs inside the outer shell 1, it will impact open the flame retardant encapsulation block 30, and the flame retardant inside the flame retardant encapsulation block 30 will be sprayed out and drip onto the flames, which helps to quickly extinguish the fire inside the shell.
