Description

Technical Field

[0001] This utility model relates to the field of battery module technology, and in particular to a battery module frame. Background Technology

[0002] A battery is a device that directly converts chemical energy into electrical energy. Its core structure consists of an electrolyte solution and two metal electrodes, achieving energy conversion through a redox reaction. A battery module integrates multiple individual batteries in series or parallel to form an energy storage unit with higher energy density. Existing battery modules generally consist of a frame and multiple battery cells fixed by the frame.

[0003] Chinese patent CN221766940U discloses a battery module locking frame, including a lower mounting component and an upper mounting component above it. The lower and upper mounting components are connected by a connecting component. An auxiliary fixing component is provided on the lower mounting component, and an auxiliary limiting component is provided within the lower mounting component. Several energy storage batteries are disposed within the auxiliary limiting component, and adjacent energy storage batteries are connected by a terminal communication component. This frame structure is ingeniously designed, highly practical, and easy to assemble. Using this battery module locking frame enables rapid battery assembly and replaces the existing fully enclosed shell, effectively improving heat dissipation performance during battery use and reducing safety hazards.

[0004] However, the above technical solution has the following shortcomings: When assembling the frame, it is fixed by the spiral engagement of the connecting screw and the fixing nut. Not only does it lack a positioning structure to stabilize the engagement of the nut, but the cylindrical structure of the screw makes the entire frame prone to shaking when the upper and lower mounting components are transported while fixing the battery module. Utility Model Content

The connecting mechanism includes two columns mounted on the base, a disc coaxially mounted on the columns and embedded in the circular grooves, a pressure plate embedded in the circular grooves, an insert block mounted on the pressure plate, six ring-shaped arrays extending through the pressure plate, a first bolt connecting the fixing frame and the disc, a first nut threaded onto the first bolt and abutting against the disc, and an auxiliary support block with a limiting rod. The insert block extends through the fixing frame and is inserted into the disc. The base has positioning holes for the limiting rod to be inserted.

[0007] Preferably, the fixing frame is provided with a plurality of first weight-reducing holes arranged in a linear array, and the fixing frame is provided with a plurality of reinforcing ribs.

[0008] Preferably, a rectangular connecting rod is provided through the base, the connecting rod passes through the auxiliary support block and abuts against the fixing frame.

[0009] Preferably, the connecting rod is provided with a threaded rod that passes through the fixing frame, and a second nut is threaded onto the threaded rod, with the second nut and the fixing frame abutting against each other.

[0010] Preferably, a limiting plate is provided at one end of the connecting rod, and the limiting plate abuts against the base.

[0011] Preferably, the battery module has two side plates on its side, and multiple symmetrically distributed third bolts are provided through the side plates, with the third bolts threaded onto the auxiliary support block.

[0012] Preferably, the side plate is provided with a plurality of second weight-reduction holes arranged in a linear array.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This utility model enables the rapid assembly and installation of the battery module frame through its connecting mechanism. It is not only easy to operate, but the connecting parts also have the functions of mutual cooperation and positioning restriction, which fully ensures the structural strength and stability of the frame, avoids shaking during transportation, ensures the safety of the battery module, and has good practicality.

[0020] Example 1

[0021] like Figure 1 - Figure 4 As shown, the battery module frame proposed in this embodiment includes a base 1 and a connecting mechanism; the base 1 has a placement groove, the inside of which a battery module is disposed, and a fixing frame 2 that abuts against the battery module is disposed above the base 1, and the fixing frame 2 has four circular grooves 7.

[0022] The connecting mechanism includes two columns 3 mounted on the base 1, a disc 4 coaxially mounted on the columns 3 and embedded in the circular groove 7, a pressure plate 5 embedded in the circular groove 7, an insert 6 mounted on the pressure plate 5, six ring arrays distributed through the pressure plate 5, a first bolt 8 connecting the fixing frame 2 and the disc 4, a first nut 9 threadedly connected to the first bolt 8 and abutting against the disc 4, and an auxiliary support block 10 with a limiting rod 11; the insert 6 passes through the fixing frame 2 and is inserted into the interior of the disc 4, and the base 1 is provided with a positioning hole for the limiting rod 11 to be inserted.

[0023] A rectangular connecting rod 12 is provided through the base 1. The connecting rod 12 passes through the auxiliary support block 10 and abuts against the fixing frame 2. A screw 14 is provided on the connecting rod 12, which passes through the fixing frame 2. A second nut 15 is threadedly connected to the screw 14. The second nut 15 abuts against the fixing frame 2. A limit plate 13 is provided at one end of the connecting rod 12, and the limit plate 13 abuts against the base 1.

[0024] In this embodiment, when the battery module needs to be installed, the battery module is first placed in the placement slot of the base 1. Then, the limiting rod 11 on the auxiliary support block 10 is inserted into the positioning hole of the base 1. Next, the circular groove 7 below the fixing frame 2 is aligned with the disc 4, so that the fixing frame 2 fits against the top surface of the battery module. Then, the pressure plate 5 is placed into the upper circular groove 7, and the insert 6 passes through the fixing frame 2 and is inserted into the interior of the disc 4 to play a role in positioning and reinforcing the connection. Then, multiple first bolts 8 are sequentially inserted through the disc 4 along the circumference of the pressure plate 5, and the first nut 9 is screwed onto the first bolts 8. The fixing frame 2 and the base 1 are fixedly connected. Then, the end of the connecting rod 12 with the screw 14 passes through the base 1 and the auxiliary support block 10 from below and is pushed into the fixing frame 2 until the limiting plate 13 abuts against the base 1. At this time, the screw 14 passes through the fixing frame 2. Then, the second nut 15 is screwed onto the screw 14. The rectangular cross-section of the connecting rod 12 reduces the difficulty of screwing the second nut 15, thereby completing the fixed installation of the battery module. It is not only simple to operate, but also has a stable connection, avoiding the problem of shaking during transportation, and has good practicality.

[0025] Example 2

[0026] like Figure 1 and Figure 4 As shown, in this embodiment, a battery module frame is provided. Compared with the first embodiment, in this embodiment, the fixing frame 2 is provided with a plurality of linearly arrayed first weight-reducing holes 18, and the fixing frame 2 is provided with a plurality of reinforcing ribs 20.

[0027] The battery module has two side plates 16 on its side. Multiple symmetrically distributed third bolts 17 are provided through the side plates 16. The third bolts 17 are threaded to the auxiliary support blocks 10. Multiple linearly arrayed second weight reduction holes 19 are provided on the side plates 16. After the auxiliary support blocks 10 are fixed, the side plates 16 are fixedly installed on the auxiliary support blocks 10 on both sides by the third bolts 17.

[0028] In this embodiment, the structural design of the first weight-reducing hole 18 and the second weight-reducing hole 19 is used to reduce the weight of the entire frame and save raw materials. The reinforcing rib 20 is used to improve the structural strength of the fixing frame 2 to ensure the stability of the frame. At the same time, the side plate 16 connects the two ends of the frame, which not only further improves the structural strength of the frame, but also strengthens the protection of the side of the battery module.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
