Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery module technology, and specifically relates to a novel battery module structure. Background Technology
[0002] Battery modules play a vital role as energy storage units across various industries. For example, power batteries are widely used in new energy vehicles and other fields. Power batteries are generally composed of multiple individual cells connected in series or parallel to form battery modules to achieve charging and discharging. As stated in the specification of application number 202223157466.1, battery modules, especially lithium iron phosphate batteries, are prone to bulging during use. When they are grouped using methods similar to plastic steel strapping or steel strapping, no space is left for the bulging of the cells, which can easily cause the cells to catch fire and cause danger. Although this patent provides space for the bulging of the battery modules, it does not include an outer casing, which allows the battery modules to be directly exposed to the air, resulting in poor external protection. They are easily damaged in the event of a collision or scratch, thus limiting their use. Utility Model Content
[0003] The purpose of this invention is to provide a novel battery module structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A novel battery module structure includes:
[0006] The outer casing has a cover plate installed at its upper end. Inside the outer casing, a battery module is installed via a limiting mounting assembly. The limiting mounting assembly includes a transverse limiting plate, a longitudinal baffle, an adjustable component one, and an adjustable component two. The two sets of transverse limiting plates and the two sets of longitudinal baffles form a rectangular frame structure for fixing the battery module around it. The two sets of longitudinal baffles are connected to the transverse limiting plates via the adjustable component one. The longitudinal baffles include longitudinal baffle one and longitudinal baffle two, which are connected via the adjustable component two. The adjustable component one and adjustable component two can connect the transverse limiting plates and the longitudinal baffles while also accommodating a certain degree of expansion of the battery module.
[0007] Preferably, the adjustable component two includes a longitudinal limiting plate, a limiting post one, a limiting sleeve one, and a strip groove one. The longitudinal limiting plate is located between two adjacent sets of longitudinal baffles one and two. The strip groove one is formed inside both ends of the longitudinal limiting plate. The limiting post one is connected to the outer end of the side of the longitudinal baffles one and two that are close to each other. The limiting post one is located inside the strip groove one. The limiting post one cooperates with the strip groove one, allowing the limiting post one to move to a certain extent inside the strip groove one, accommodating a certain degree of expansion of the battery module. The limiting sleeve is threaded to the outer end of the limiting post one. First, when installing the longitudinal limiting plate between the longitudinal baffle one and the longitudinal baffle two, firstly, the strip grooves one at both ends of the longitudinal limiting plate are respectively fitted onto the outer side of the corresponding limiting post, and then the corresponding limiting sleeve one is rotated and tightened so that the inner side of the limiting sleeve one can clamp the longitudinal limiting plate. When the battery module is used for a long time and expands to a certain extent, it can squeeze the transverse limiting plate and the longitudinal baffle. At this time, the two sets of longitudinal baffle one and the longitudinal baffle two move to a certain extent. At this time, the limiting post one can move to a certain extent inside the strip groove one, and the limiting sleeve one makes a certain displacement relative to the longitudinal limiting plate to adapt to the expansion of the battery module.
[0008] Preferably, the adjustable component includes a second strip groove, a second limiting post, and a second limiting sleeve. The second strip groove is formed inside both ends of the transverse limiting plate. The outer sides of both the first and second longitudinal baffles are connected to the second limiting post, which mates with the second strip groove. The second limiting post is located inside the second strip groove, and the outer side of the second limiting post is threadedly connected to the second limiting sleeve. During installation, the second limiting posts on the outer sides of the first and second longitudinal baffles are similarly installed inside the corresponding second strip groove of the transverse limiting plate, and then... Do not tighten the second limiting sleeve, so that the inner side of the second limiting sleeve clamps the end face of the transverse limiting plate. Similarly, when the battery module is used for a long time and expands to a certain extent, it can squeeze the transverse limiting plate and the longitudinal baffle. At this time, the second limiting post can move to a certain extent inside the second strip groove. The second limiting sleeve can move to a certain extent relative to the transverse limiting plate to adapt to the expansion of the battery module. Furthermore, the second strip groove and the first strip groove, the second limiting post and the first limiting post, and the second limiting sleeve and the first limiting sleeve have the same structure and play the same role.
[0009] Preferably, the lower ends of both the first and second longitudinal baffles are connected to movable limiting blocks. The bottom end of the outer shell is provided with a movable limiting groove that cooperates with the movable limiting block. The volume of the movable limiting groove is larger than that of the movable limiting block, which is conducive to the movable limiting block moving laterally and longitudinally within a certain range. A rubber pad is provided on the outside of the movable limiting block, which can fill the inside of the movable limiting groove. At the same time, it has elastic expansion and contraction properties, and can also adapt to the movement of the movable limiting block to a certain extent when the first and second longitudinal baffles move to accommodate the expansion of the battery module.
[0010] Preferably, each end of the cover plate is provided with a mounting bolt, and the upper end of the outer shell is provided with a screw hole that mates with the mounting bolt for mounting bolt installation, so that the cover plate can be closed on the upper end of the outer shell.
[0011] Preferably, the lower end of the cover plate is provided with a rubber pressing block, which is made of rubber material. After the cover plate is installed on the upper end of the outer shell, it can squeeze the battery module to achieve upper limit fixation. The rubber pressing block also has a certain degree of expansion and contraction performance, and can also adapt to the expansion of the battery module in the vertical direction.
[0012] Preferably, both the first and second longitudinal baffles have several sets of heat dissipation holes inside to provide ventilation and heat dissipation. The transverse limiting plate is a plate-shaped structure, which can install and fix the battery module without affecting heat dissipation.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model provides effective external protection by placing the battery module between the outer shell and the cover plate. The included limiting installation components not only secure the battery module but also accommodate its expansion. The limiting installation components include a transverse limiting plate, a longitudinal baffle, an adjustable component one, and an adjustable component two. The two transverse limiting plates and two longitudinal baffles form a rectangular frame structure to secure the battery module. The adjustable components one and two connect the transverse limiting plates and the longitudinal baffles while also accommodating the expansion of the battery module. Attached Figure Description

A limiting post 24 is connected to the outer end of the side of the longitudinal baffles 21 and 22 that are close to each other. The limiting post 24 is located inside the strip groove 1 and cooperates with it, allowing it to move to a certain extent within the strip groove 1 to accommodate a certain degree of expansion of the battery module 11. A limiting sleeve 25 is threaded to the outer end of the limiting post 24. The longitudinal limiting plate 23 is installed... When the longitudinal baffle 1 21 and the longitudinal baffle 22 are in contact, the strip grooves at both ends of the longitudinal limiting plate 23 are first fitted onto the outer side of the corresponding limiting post, and then the corresponding limiting sleeve 1 25 is rotated and tightened so that the inner side of the limiting sleeve 1 25 can clamp the longitudinal limiting plate 23. When the battery module 11 is used for a long time and expands to a certain extent, it can squeeze the transverse limiting plate 20 and the longitudinal baffle.

The rubber pressing block 14 has a certain degree of expansion and contraction performance and can also adapt to the expansion of the battery module 11 in the vertical direction.
[0031] refer to Figures 1-4 As shown, both the longitudinal baffle 1 21 and the longitudinal baffle 22 have several sets of heat dissipation holes 32 inside, which serve to ventilate and dissipate heat.
