Description

Technical Field

[0001] This utility model relates to the field of battery explosion-proof protective shell technology, specifically an explosion-proof protective shell based on a parking lithium iron phosphate battery. Background Technology

[0002] Lithium iron phosphate (LFP) batteries are lithium-ion batteries that use lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. With the development of battery and new energy vehicle technologies, LFP batteries have been widely used. However, due to the inherent dangers of these batteries, protective structures are needed to protect them.

[0003] For example, Chinese Patent (Announcement No.: CN219873835U) discloses an explosion-proof protective shell based on a lithium iron phosphate battery, including a protective shell with a placement groove inside. The placement groove holds the lithium iron phosphate battery body. The inner wall of the placement groove has vertically distributed sliding grooves on opposite sides. Two symmetrically distributed buffer blocks slide within the sliding grooves. A buffer rod is hinged to the side of the buffer block facing the lithium iron phosphate battery body. A buffer spring provides a counter-thrust force to buffer the impact of the lithium iron phosphate battery body on the buffer block, buffer rod, and buffer plate. In conjunction with a spring damper to control the movement of the buffer plate, the buffer is completely buffered when the lithium iron phosphate battery body is impacted, thus protecting the lithium iron phosphate battery body from explosion due to collision and improving the service life of the lithium iron phosphate battery body.

[0004] However, the aforementioned patent has some shortcomings. Its outer shell is an integrated structure. When one side of the protective shell is deformed by an external impact, the entire shell needs to be disassembled and replaced, which reduces the practicality of the device and makes it inconvenient to use. Therefore, an explosion-proof protective shell based on a parking lithium iron phosphate battery is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an explosion-proof protective shell based on a parking lithium iron phosphate battery. It features a split design for easy replacement of damaged shells and solves the problem that the main body of the shell in the aforementioned patents is an integrated structure, requiring the entire shell to be disassembled and replaced when one side of the protective shell is deformed by external impact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof protective shell based on a parking lithium iron phosphate battery, comprising a lithium iron phosphate battery body, two mounting plates on both the left and right sides of the lithium iron phosphate battery body, mounting mechanisms on both the left and right sides of the lithium iron phosphate battery body, and an explosion-proof mechanism on the mounting plates;

[0007] The mounting mechanism includes four square compartments, each fixed to one side of the mounting plate facing the lithium iron phosphate battery body. Each square compartment has a screw rotatably connected to its front and rear sides. A threaded cylinder is threaded onto the outer peripheral wall of each screw. A clamping plate is fixed to the side of the threaded cylinder facing away from the square compartment. A guide block is fixed to the outer peripheral wall of the threaded cylinder. The mounting plate has a guide groove on the side facing the lithium iron phosphate battery body for sliding connection of the guide block. A worm gear is rotatably connected between the front and rear inner walls of each square compartment, and the worm gear is fixed to the screws on its front and rear sides. Each side of the lithium iron phosphate battery body has a worm gear that vertically penetrates the square compartment and rotatably connects to it, and the worm gear meshes with the worm gear.

[0008] Furthermore, the explosion-proof mechanism includes a damper fixed to the side of the mounting plate away from the lithium iron phosphate battery body. A damping spring is fitted on the outer peripheral wall of the damper. Annular plates fixed to the damper are provided on both the left and right sides of the lithium iron phosphate battery body. Four mounting holes are opened on the side of the annular plate away from the lithium iron phosphate battery body. An explosion-proof plate is installed on the side of the annular plate away from the lithium iron phosphate battery body. A bolt with one end fixed to the explosion-proof plate is inserted into the mounting hole, and a nut is threaded onto the outer peripheral wall of the bolt.

[0009] Furthermore, the two mounting plates on the same side are arranged vertically, and the screw extends into the interior of the square compartment from the side closest to it.

[0010] Furthermore, the guide groove is used to allow the guide block to slide back and forth inside it, and the two screws that are opposite to each other have opposite thread directions.

[0011] Furthermore, a rubber pad is fixed to the side of the clamping plate facing the lithium iron phosphate battery body, and two worm gears on the same side mesh with the same worm. A circular plate is fixed to the top of the worm, and an anti-slip groove is formed on the outer peripheral wall of the circular plate.

[0012] Furthermore, two dampers are provided on the same mounting plate, and four dampers on the same side of the lithium iron phosphate battery body are fixed to the same annular plate, which is a rectangular annular plate.

[0013] Furthermore, the four mounting holes are located near the four corners on the left side of the annular plate, and the nut is located on the side of the annular plate facing the lithium iron phosphate battery body.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This explosion-proof protective shell, based on a lithium iron phosphate battery for parking, allows the mounting plate to be directly installed on the side of the lithium iron phosphate battery body via an installation mechanism. The explosion-proof mechanism on the mounting plate provides explosion protection. Each mounting mechanism on the side of the lithium iron phosphate battery body is independently designed. If one side is damaged, the explosion-proof mechanism on that side can be disassembled and replaced using the installation mechanism. The split design makes it easier to install, remove, and repair, improving its practicality and facilitating its widespread use. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1This embodiment provides an explosion-proof protective shell based on a parking lithium iron phosphate battery, comprising a lithium iron phosphate battery body 1. Two mounting plates 2 are provided on both the left and right sides of the lithium iron phosphate battery body 1, arranged vertically on the same side. Mounting mechanisms are provided on both the left and right sides of the lithium iron phosphate battery body 1, and explosion-proof mechanisms are provided on the mounting plates 2. In use, the mounting plates 2 are directly mounted on the sides of the lithium iron phosphate battery body 1 via the mounting mechanisms, and the explosion-proof mechanisms on the mounting plates 2 provide explosion-proof protection for the lithium iron phosphate battery body 1. The mounting mechanisms on the sides of the lithium iron phosphate battery body 1 are all independently provided. When one side is damaged, the explosion-proof mechanism on that side can be disassembled and replaced using the mounting mechanism. The split design facilitates installation, disassembly, and maintenance, improves practicality, and makes it easier to promote and use.

[0023] It should be understood that, in actual use, the installation mechanism and the explosion-proof mechanism are added to different sides of the lithium iron phosphate battery body 1 for explosion-proof protection according to the usage requirements.

[0024] Please see Figure 1-3 The mounting mechanism includes four square compartments 301 fixed to the sides of four mounting plates 2 facing the lithium iron phosphate battery body 1. Screws 302 are rotatably connected to both the front and rear sides of each square compartment 301. Two opposing screws 302 have opposite thread directions. The screws 302 extend into the square compartment 301 from the side closest to it. A threaded cylinder 303 is threadedly connected to the outer peripheral wall of the screw 302. A clamping plate 304 is fixed to the side of the threaded cylinder 303 facing away from the square compartment 301. A guide block 305 is fixed to the outer peripheral wall of the threaded cylinder 303. A guide groove 306 is provided on the side of the mounting plate 2 facing the lithium iron phosphate battery body 1 for the guide block 305 to slide in. The guide groove 306 allows the guide block 305 to slide back and forth within it. A worm gear 3 is rotatably connected between the front and rear inner walls of the square compartment 301. 07, and the worm gear 307 is fixed to the screws 302 on its front and rear sides. The left and right sides of the lithium iron phosphate battery body 1 are provided with worm gears 308 that vertically penetrate the square compartment 301 and are rotatably connected to it. The worm gears 308 mesh with the worm gears 307. In use, the mounting plate 2 is placed on the side of the lithium iron phosphate battery body 1 and the clamping plate 304 is located at the edge of the lithium iron phosphate battery body 1. Then the worm gears 308 are rotated. The same worm gear 308 drives the two worm gears 307 on one side to rotate. The worm gears 307 drive the screws 302 on its front and rear sides to rotate synchronously and in the same direction. This causes the screws 302 to drive the threaded cylinders 303 on its front and rear sides to slide relative to each other with the guide block 305 and the guide groove 306. This causes the clamping plate 304 to clamp the mounting plate 2 on the side of the lithium iron phosphate battery body 1.

[0025] A rubber pad is fixed to the side of the clamping plate 304 facing the lithium iron phosphate battery body 1. Two worm gears 307 on the same side mesh with the same worm 308. A circular plate 309 is fixed to the top of the worm 308, and an anti-slip groove is provided on the outer peripheral wall of the circular plate 309. The circular plate 309 and the anti-slip groove on its outer peripheral wall facilitate the rotation of the worm 308, thereby driving the clamping plate 304 to perform clamping and installation.

[0026] Please see Figure 1 and Figure 4 In this embodiment, the explosion-proof mechanism includes a damper 401 fixed to the side of the mounting plate 2 away from the lithium iron phosphate battery body 1. A damping spring 402 is fitted on the outer peripheral wall of the damper 401. Annular plates 403, fixed to the damper 401, are provided on both the left and right sides of the lithium iron phosphate battery body 1. Four mounting holes 404 are opened on the side of the annular plate 403 away from the lithium iron phosphate battery body 1. An explosion-proof plate 405 is installed on the side of the annular plate 403 away from the lithium iron phosphate battery body 1. After the mounting plate 2 is installed on the side of the lithium iron phosphate battery body 1, when an external object impacts the lithium iron phosphate battery body 1, it will impact the explosion-proof plate 405. 05 drives the annular plate 403 to move closer to the lithium iron phosphate battery body 1 and compress the damper 401 and damping spring 402. The damper 401 and damping spring 402 play a buffering and protective role, thereby preventing damage to the lithium iron phosphate battery body 1. A bolt 406 with one end fixed to the explosion-proof plate 405 is inserted into the mounting hole 404. A nut 407 is threaded on the outer peripheral wall of the bolt 406. The nut 407 is located on the side of the annular plate 403 facing the lithium iron phosphate battery body 1. When the explosion-proof plate 405 is damaged, the nut 407 can be unscrewed to disassemble and replace the explosion-proof plate 405, ensuring the explosion-proof protection effect of the lithium iron phosphate battery body 1.

[0027] Two dampers 401 are provided on the same mounting plate 2. The four dampers 401 on the same side of the lithium iron phosphate battery body 1 are fixed to the same annular plate 403. The annular plate 403 is a rectangular annular plate, and the four mounting holes 404 are respectively close to the four corners on the left side of the annular plate 403.

[0028] The working principle of the above embodiments is as follows:

[0029] (1) When in use, place the mounting plate 2 on the side of the lithium iron phosphate battery body 1 and position the clamping plate 304 at the edge of the lithium iron phosphate battery body 1. Then rotate the worm 308. The same worm 308 drives the two worm wheels 307 on one side to rotate. The worm wheels 307 drive the screws 302 on the front and rear sides to rotate synchronously and in the same direction. This causes the screws 302 to drive the threaded cylinders 303 on the front and rear sides to slide relative to each other with the guide block 305 and the guide groove 306. This causes the clamping plate 304 to clamp the mounting plate 2 on the side of the lithium iron phosphate battery body 1 for fixed installation.

[0030] (2) After the mounting plate 2 is installed on the side of the lithium iron phosphate battery body 1, when an external object hits the lithium iron phosphate battery body 1, it will hit the explosion-proof plate 405. The explosion-proof plate 405 drives the annular plate 403 to move closer to the lithium iron phosphate battery body 1 and compress the damper 401 and the damping spring 402. The damper 401 and the damping spring 402 play a buffer protection role, thereby avoiding damage to the lithium iron phosphate battery body 1. When the explosion-proof plate 405 is damaged, the nut 407 can be unscrewed to disassemble and replace the explosion-proof plate 405 to ensure the explosion-proof protection effect of the lithium iron phosphate battery body 1.
