Technical Field
[0001] This utility model relates to the field of lithium battery technology, and in particular to a special plastic shell for use in an automated production line for lithium battery modules. Background Technology
[0002] Due to their environmentally friendly and energy-saving characteristics, lithium-ion batteries, which consist of multiple individual cells connected in series, parallel, or series-parallel, require a protective casing to be installed on their surface during the manufacturing process to protect them due to their large capacity and high discharge rate.
[0003] Traditional battery housings typically house several lithium battery modules arranged sequentially inside the housing. The housing is then sealed with adhesive to ensure its integrity and stable installation. However, in practice, the adhesive sealing method is difficult to reverse. This means that when the lithium battery modules need repair or maintenance, they can only be disassembled forcefully, which can damage the housing, affecting subsequent normal use and increasing the cost of using lithium batteries.

[0009] Preferably, a reinforcing ring is fitted onto the arc surface of the bolt, and the reinforcing ring abuts against the surface of the fixing plate.
[0010] The effect achieved by the above components is that the setting of the reinforcing ring makes the bolts fit more stably and securely when installed on the fixing plate, thereby better ensuring the stability of the cover and facilitating the subsequent inspection and maintenance of the lithium battery module.
[0011] Preferably, one side of the fixing plate has an arc-shaped cross-section, a sliding rod is slidably connected through the surface of the fixing frame, one end of the sliding rod is fixedly connected to an insert block, a spring is sleeved on the arc surface of the sliding rod, and the two ends of the spring are fixedly connected to the insert block and the inner wall of the fixing frame, respectively.

[0013] Preferably, a reinforcing pad, which is a rubber pad, is fixedly connected to the inner wall of the fixing plate.
[0014] The effect achieved by the above components is that, by setting the reinforcing pad, the friction is further increased when the fixing plate and the fixing frame are engaged, and gaps are less likely to occur, thereby making the connection more stable and firm, and improving the positional stability of the cover.
[0015] Preferably, protective devices are provided on both sides of the surface of the housing body. The protective devices include protective covers, which are placed on the surface of the components of the connecting device.

It also facilitates the proper installation of the housing body.
[0017] Preferably, the protective cover has reinforcing grooves on both sides of its surface, and reinforcing plates are inserted into the inner walls of the reinforcing grooves. The reinforcing plates are fixedly connected to the surface of the housing body.
[0018] The effect achieved by the above components is that, through the insertion of the reinforcing plate and the reinforcing groove, when the protective cover covers the surface of the connecting device, it is not easy to shake, and the position can be better maintained, thereby providing better shielding and protection for the components of the device.

It is also less likely to be damaged and can be reused multiple times, reducing usage costs and improving the practicality and effectiveness of the housing body. Attached Figure Description

A fixing plate 43 is rotatably connected to the arc surface of the rotating shaft bracket 42. The fixing plate 43 has an "L" shaped cross section. Fixing frames 41 are fixedly connected to both sides of the surface of the housing cover 3. The fixing plate 43 is engaged with the inner wall of the fixing frame 41. A bolt 44 is inserted through the surface of the fixing plate 43. The bolt 44 is threaded to one side of the fixing frame 41. When the lithium battery module is assembled in the housing body 1, several lithium battery modules are first placed sequentially into the inner wall of the housing body 1, and then the sealing ring 2 is... Install the cover at the opening on the surface of the housing body 1, then snap the cover onto the surface of the housing body 1. Then rotate the fixing plates 43 on both sides of the surface of the housing body 1 so that the fixing plates 43 snap into the inner wall of the fixing frame 41 on one side of the cover. Then, the bolts 44 pass through the surface of the fixing plates 43 until the threads are connected to the surface of the fixing frame 41, thus fixing the position of the cover. At this time, when the housing body 1 is used in the assembly of the lithium battery module, it is more convenient to inspect and maintain the lithium battery module, which improves its working efficiency and makes it less likely to be damaged. It can be reused many times, reducing the cost of use and improving the practicality and use effect of the housing body 1.
[0030] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses that two rotating shaft brackets 42 have torsion springs 45 respectively fitted on the arc surfaces of the two rotating shaft brackets 42 on both sides of the fixing plate 43. The two ends of the torsion springs 45 are fixedly connected to the rotating shaft brackets 42 and the fixing plate 43 respectively. With the setting of the torsion springs 45, when the cover is snapped onto the surface of the housing body 1, the fixing plate 43 can be quickly inserted into the fixing frame 41 under the torsional force of the torsion springs 45, which improves the convenience of using the device and also improves the maintenance efficiency of the lithium battery module. A reinforcing ring 46 is fitted on the arc surface of the bolt 44. The reinforcing ring 46 abuts against the surface of the fixing plate 43. With the setting of the reinforcing ring 46, the bolt 44 is more stably fitted when installed on the fixing plate 43, thereby better ensuring the stability of the cover and facilitating the subsequent maintenance of the lithium battery module.
[0031] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this embodiment discloses that one side of the fixing plate 43 has an arc-shaped cross-section, and a sliding rod 47 is slidably connected through the surface of the fixing frame 41. One end of the sliding rod 47 is fixedly connected to an insert block 48, and a spring 49 is sleeved on the arc surface of the sliding rod 47. The two ends of the spring 49 are fixedly connected to the insert block 48 and the inner wall of the fixing frame 41, respectively. A slot 410 is provided on one side of the fixing plate 43, and the insert block 48 is inserted into the inner wall of the slot 410. When the fixing plate 43 is inserted into the inner wall of the fixing frame 41, the insert block 48 can be pushed open. Then, when fully engaged, the insert rod will drive the insert block 48 into the slot 410 under the elastic force of the spring 49, thereby ensuring the position of the fixing plate 43 is fixed and facilitating the insertion and fixing of the bolt 44. The inner wall of the fixing plate 43 is fixedly connected with a reinforcing pad 411, which is a rubber pad. By setting the reinforcing pad 411, when the fixing plate 43 and the fixing frame 41 are engaged, the friction is further increased and it is not easy for gaps to be generated, thereby making the connection more stable and firm and improving the positional stability of the cover 3.

The surface of the protective cover 51 has mounting holes 52, and bolts 44 are inserted into the inner wall of the mounting holes 52. When the housing body 1 is assembling and fixing the lithium battery module, after the fixing plate 43 is snapped into the inner wall of the fixing frame 41, the protective cover 51 is covered on the components of the connecting device 4, and then the bolts 44 are inserted into the mounting holes 52 on the surface of the protective cover 51 to fix the position of the protective cover 51. At this time, when the housing body 1 is assembled and used, the components of the connecting device 4 are not easily exposed to the outside, and do not come into contact or collide with other equipment and devices, resulting in damage to the components or equipment. It also facilitates the proper installation of the housing body 1.

A reinforcing plate 54 is inserted into the inner wall of the reinforcing groove 53. The reinforcing plate 54 is fixedly connected to the surface of the housing body 1. Through the insertion of the reinforcing plate 54 and the reinforcing groove 53, the protective cover 51 is less likely to shake when it covers the surface of the connecting device 4, and can better maintain the stability of its position, thereby better shielding and protecting the components of the device. The protective cover 51 has anti-slip grooves 55 on both sides of its surface. The inner wall of the anti-slip groove 55 has several anti-slip protrusions. Through the setting of the anti-slip groove 55, the protective cover 51 is more stable and convenient to hold when disassembling and assembling, and is less likely to slip out of the hand, thereby improving the convenience of using the protective device 5.
[0034] Working principle: When the lithium battery module is assembled in the housing body 1, several lithium battery modules are first placed sequentially into the inner wall of the housing body 1. Then, the sealing ring 2 is installed at the opening on the surface of the housing body 1. The cover is then clipped onto the surface of the housing body 1. The fixing plates 43 on both sides of the surface of the housing body 1 are then rotated so that the fixing plates 43 are clipped into the inner wall of the fixing frame 41 on one side of the cover. When the fixing plates 43 are inserted into the inner wall of the fixing frame 41, the insert block 48 can be pushed open. When fully clipped, the insert rod will drive the insert block 48 into the slot 410 under the elastic force of the spring 49. Then, the bolt 44 passes through the surface of the fixing plate 43 until the thread is threaded with the surface of the fixing frame 41, thus fixing the position of the cover. At this time, when the housing body 1 is used for the assembly of lithium battery modules, it is more convenient to inspect and maintain the lithium battery modules, improving its working efficiency. It is also less likely to damage the housing body 1, and it can be reused multiple times, reducing the cost of use and improving the practicality and effectiveness of the housing body 1.
[0035] When the housing body 1 is used to assemble and fix the lithium battery module, after the fixing plate 43 is snapped into the inner wall of the fixing frame 41, the protective cover 51 is covered on the components of the connecting device 4. Then, the bolt 44 is inserted into the mounting hole 52 on the surface of the protective cover 51 to fix the position of the protective cover 51. The inner wall of the protective cover 51 is inserted into the reinforcing groove 53 on the surface of the housing body 1 and the reinforcing plate 54. At this time, when the housing body 1 is assembled and used, the components of the connecting device 4 are not easily exposed to the outside and do not come into contact or collide with other equipment and devices, which may cause damage to the components or equipment. It also facilitates the proper installation of the housing body 1.
