Description

Technical Field

[0001] This utility model relates to the field of battery module technology, specifically a battery module with high safety performance. Background Technology

[0002] A battery module is a unit composed of multiple battery cells connected in series and parallel. Through reasonable design and layout, the battery module can maximize the energy density and power density of the battery to meet the power requirements of electric vehicles, energy storage systems and other applications. The structural design of the battery module plays a supporting and fixing role for the battery cells, preventing the cells from being damaged by vibration or impact.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN211879445U) discloses a battery module with high safety performance. The module includes a housing, an inner bottom wall with a mounting groove, a fixing ear fixedly connected to one side of the housing, a through hole at the top of the fixing ear, a movable rod movably connected to the inner wall of the through hole, a fixing groove on the inner side wall of the housing, a wear-resistant pad fixedly connected to the inner wall of the fixing groove, and a shock-absorbing spring fixedly connected to the inner wall of the wear-resistant pad. This high-safety battery module achieves its intended high safety performance, thus solving the problem of low safety performance in general battery modules. It provides better protection against severe impacts and rollovers, preventing breakage and explosions, thus giving users greater peace of mind and further meeting their needs, bringing convenience to their work.

[0004] Although the aforementioned patent provides some protection for the battery module by using wear-resistant pads and shock-absorbing springs to prevent lateral damage during impacts or rollovers, when the battery module is impacted and rolls, the module can only offset part of the lateral impact force through the lateral shock-absorbing springs. The impact force at the other two ends cannot be offset, which greatly increases the possibility of battery damage and is not conducive to improving the service life of the battery module.

[0005] Therefore, this utility model provides a battery module with high safety performance to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a battery module with high safety performance, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-safety-performance battery module includes a battery body, a mounting bracket is snapped onto the outer wall of the battery body, an mounting block is fixedly connected to the side wall of the mounting bracket, and a safety component is provided on the outer wall of the battery body.

[0011] The safety component includes a connecting shell fixedly connected to the outer wall of the battery body, a protective sleeve fixedly connected to the outer wall of the connecting shell, the interior of the protective sleeve being filled with a non-Newtonian fluid, a contact shell fixedly sleeved to the outer wall of the protective sleeve, and a plurality of sliding grooves formed on the outer wall of the contact shell, with a contact rod slidably connected to the inner wall of the sliding groove.

[0012] As a preferred technical solution of this application, a plurality of springs are fixedly connected to the outer wall of the contact shell, and a baffle is fixedly connected to the outer wall of the springs, wherein a plurality of rubber strips are fixedly connected to the outer wall of one of the baffles.

[0013] As a preferred technical solution of this application, the bottom end of the card holder is fixedly connected to a housing, and the inner side wall of the housing is slidably connected to a top cover.

[0014] As a preferred technical solution of this application, a heat dissipation plate for improving battery heat dissipation is fixedly connected to the middle of the top cover, and a dustproof plate is fixedly connected to the inner side wall of the top cover above the heat dissipation plate.

[0015] As a preferred technical solution of this application, the outer side wall of the top cover is fixedly connected to a mounting base, and the upper top of the mounting base is provided with a mounting groove for easy connection with the upper top of the outer shell.

[0016] As a preferred technical solution of this application, the outer wall of the housing is symmetrically and fixedly connected with handles, and the outer wall of the housing is fixedly connected with multiple shock-absorbing balls.

[0017] (III) Beneficial Effects

[0018] By incorporating safety components, the risk of damage to the battery module can be reduced. The combination of multiple springs and baffles on the outside of the battery body can buffer some minor impacts. When a severe impact hits the battery module, the pressure will cause the contact rod sliding on the outer wall of the contact shell to quickly abut against the protective sleeve, thereby causing the non-Newtonian fluid filled inside to quickly change from a liquid to a solid state. This counteracts the impact on the battery module, prevents damage from collisions, improves its safety, reduces the risk of spontaneous combustion, and extends its service life.

[0026] 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.

[0027] This utility model provides a battery module, such as Figures 1-5 As shown, this high-safety-performance battery module includes a battery body 1, a card holder 2 is snapped onto the outer wall of the battery body 1, an mounting block 3 is fixedly connected to the side wall of the card holder 2, and a safety component is provided on the outer wall of the battery body 1.

[0028] The safety component includes a connecting shell 4 fixedly connected to the outer wall of the battery body 1. A protective sleeve 5 is fixedly connected to the outer wall of the connecting shell 4. The interior of the protective sleeve 5 is filled with a non-Newtonian fluid 6. A contact shell 7 is fixedly sleeved on the outer wall of the protective sleeve 5. Multiple grooves 8 are provided on the outer wall of the contact shell 7. A contact rod 9 is slidably connected to the inner wall of the groove 8.

[0029] Multiple springs 10 are fixedly connected to the outer wall of the contact shell 7, and baffles 11 are fixedly connected to the outer wall of the springs 10. Multiple rubber strips are fixedly connected to the outer wall of one of the baffles 11.

[0030] Specifically, the mounting bracket 2 on the outer wall of the battery body 1 securely holds the battery in place, preventing it from loosening due to external shaking during use. The mounting block 3 on the side wall of the mounting bracket 2 stably fixes it to the inner wall of the outer casing 12. This connection between the outer casing 12 and the external fixing device improves the stability of the battery body 1. The connecting shell 4 on the outer wall of the battery body 1 securely connects to the protective sleeve 5, improving the connection stability and preventing damage to the battery module from the non-Newtonian fluid 6 changing state. When the outer casing 12 is impacted, it is first partially cushioned by the baffle 11 and the spring 10 connected to its inner wall. However, if the impact force is too large… When the baffle 11 and spring 10 cannot be buffered by the material properties of the main body, the baffle 11 will impact the outer wall of the contact shell 7, thereby causing multiple contact rods 9 on the outer wall of the contact shell 7 to slide towards the protective sleeve 5. Through the multi-directional impact of multiple contact rods 9 on the protective sleeve 5, the non-Newtonian fluid 6 filled inside the protective sleeve 5 can be instantly converted from liquid to solid, forming a sufficiently stable protective layer for the battery body 1, avoiding damage to the battery body 1 caused by impact, and reducing the risk of battery fire caused by impact force. This component has a simple structure and strong practicality. It will not increase the weight of the battery module too much and affect its portability, and can improve the safety of the battery module by working with the protective sleeve 5 through the baffle 11 and spring 10.

[0031] The bottom end of the card holder 2 is fixedly connected to the outer shell 12, and the inner side wall of the outer shell 12 is slidably connected to the top cover 13.

[0032] A heat dissipation plate 14 for improving battery heat dissipation is fixedly connected to the middle of the top cover 13, and a dustproof plate is fixedly connected to the inner side wall of the top cover 13 above the heat dissipation plate 14.

[0033] A mounting base 15 is fixedly connected to the outer side wall of the top cover 13, and the top end of the mounting base 15 is provided with a mounting groove to facilitate connection with the top end of the outer shell 12.

[0034] The outer wall of the outer casing 12 is symmetrically and fixedly connected with handles 16, and multiple shock-absorbing balls are also fixedly connected to the outer wall of the outer casing 12.

[0035] Specifically, by providing a shell 12 and a top cover 13 on the outer wall of the battery body 1, the protection of the battery body 1 can be improved, preventing damage to the battery body 1 from stones or other debris in the external environment. The top cover 13, which is slidably connected, also facilitates the replacement and maintenance of the battery by the operator. The mounting base 15 on the side wall of the top cover 13 allows the top cover 13 and the shell 12 to be threaded together with screws, further improving the tightness of the connection between the two. By providing a heat dissipation plate 14 in the middle of the top cover 13, the heat of the battery can be dissipated, preventing the battery body 1 from overheating and affecting its stability. The handle 16 on the outer wall of the shell 12 makes it easy for the operator to carry the battery module, greatly improving its portability.
