[0002] Chinese patent document CN221262593U discloses a lower housing of a battery pack, a battery pack housing, and a battery pack. The lower housing includes a lower housing body, a connecting portion, and a crossbeam. The lower housing body includes a base plate, two end plates spaced apart from the base plate, and two side plates spaced apart from the base plate, forming a mounting cavity. The connecting portion has a mounting groove on the side of each side plate facing the mounting cavity. The crossbeam is located within the mounting cavity, with its end embedded in the mounting groove, and the end of the crossbeam mates with the mounting groove to connect the crossbeam and the side plates. The technical solution of this utility model solves the problem of low production efficiency of the lower housing of the battery pack caused by the use of welding, bolting, or core-pulling riveting processes to connect the crossbeam and the side plates in the prior art.

[0003] When the battery pack casing is in use, if there is an obstacle below the battery pack casing, it is easy to have a direct hard impact with the battery pack casing. The lack of buffer protection increases the probability of casing damage and reduces the safety of battery use. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an energy storage battery pack housing includes a lower housing 1, a buffer mechanism 3, and a support mechanism 5. An upper housing 2 is provided on the top of the lower housing 1. The buffer mechanism 3 is located outside the lower housing 1 and includes a fixing block 301, a damping rod 302, and a movable plate 304. Multiple sets of fixing blocks 301 are fixedly installed on the front and rear sides of the lower housing 1. The bottom of each fixing block 301 is fixedly connected to one end of a set of damping rods 302, and the other end of each damping rod 302 is fixedly connected to the top of the movable plate 304. The support mechanism 5 is located inside the lower housing 1 and includes a mounting block 501 and positioning holes 502. A set of mounting blocks 501 are fixedly installed on the inner walls of the front and rear sides of the lower housing 1. Multiple sets of vertically penetrating positioning holes 502 are provided on the top of the mounting blocks 501, and the positioning holes 502 are equidistantly distributed. A liquid cooling component 4 is fixedly installed on the bottom inner side of the lower housing 1.

[0024] Secondly, the buffer mechanism 3 also includes a spring 303. The bottom of the fixed block 301 is fixedly connected to one end of a set of springs 303, and the other end of the springs 303 is fixedly connected to the top of the movable plate 304. The damping rod 302 passes through the inside of the springs 303 but is not connected to them. The top of the movable plate 304 is provided with a buffer pad to buffer the impact force on the battery pack shell, avoid direct hard contact, reduce the probability of damage to the upper shell 2, and improve the safety of the battery during use.

[0025] Furthermore, the support mechanism 5 also includes a plug-in plate 503, a support plate 504, and a pressing block 505. Multiple sets of support plates 504 are provided inside the lower housing 1. Plug-in plates 503 are fixedly installed on the front and rear sides of the support plates 504. The plug-in plates 503 extend into the interior of a set of positioning holes 502. A pressing block 505 is fixedly installed on the top inner side of the upper housing 2. The pressing block 505 fits against the top of the plug-in plate 503 but is not connected to it, which facilitates the adjustment of the distance between the support plates 504 according to the size of the battery pack, so that the support plates 504 will not affect the placement of the battery pack. At the same time, it can provide lateral support for the lower housing 1 and improve the stability of the housing.

[0026] Furthermore, a set of limiting holes 6 are respectively opened on the top of the fixing block 301, and multiple sets of connecting rods 7 are fixedly installed on the front and rear sides of the upper shell 2. One end of the connecting rod 7 extends into the interior of a set of limiting holes 6 to prevent the lower shell 1 and the upper shell 2 from shifting or misaligning during the welding process, thus ensuring the quality of the shell after welding.

[0027] Working principle: When using this device, insert the plug-in plates 503 into the positioning holes 502 in sequence, adjust the spacing between the support plates 504 according to the size of the battery pack to support the lower housing 1, and then install the battery pack and wiring into the lower housing 1. Insert the connecting rod 7 into the limiting hole 6 so that the upper housing 2 covers the lower housing 1 and positions the upper housing 2. At the same time, press the pressing block 505 on the top of the plug-in plates 503 to limit the plug-in plates 503. Then the lower housing 1 and the upper housing 2 can be welded together. When the lower part of the upper housing 2 is hit by an obstacle, the movable plate 304 will contact the obstacle first, causing the damping rod 302 to retract and compress the spring 303 to buffer the impact force. After the impact, under the elastic action of the spring 303, the damping rod 302 will extend, causing the movable plate 304 to be reset.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. 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 utility model.
