[0001] This utility model relates to the field of battery pack installation technology, specifically to a battery pack bracket. Background Technology

[0002] In fields such as new energy vehicles and energy storage systems, where battery safety and stability are extremely important, battery pack brackets have emerged and become an indispensable key structural component of battery packs. These brackets are designed to effectively fix and support battery modules, prevent displacement and collision damage under complex working conditions, optimize the internal space layout of the battery pack, and improve heat dissipation efficiency.

[0003] Currently, in order to achieve the goals of reducing vehicle weight and significantly reducing the size of the battery pack bracket, the space reserved for battery pack installation in the bracket is relatively small. This makes it difficult for workers to perform battery pack installation on the bracket. Conversely, if the space reserved for battery pack installation in the bracket is too large, the battery pack may loosen inside the bracket when the vehicle is subjected to vibration, which will adversely affect the stability and safety of the battery system.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0028] like Figures 1 to 8 As shown, a battery pack bracket includes: a housing 1 for supporting the battery pack, a fixing beam 2 fixedly installed on the housing 1, and an auxiliary fixing mechanism 3 for assisting in fixing the installed battery.

[0029] During the assembly of battery packs onto the battery pack bracket, crossbeams are typically added between the battery packs to enhance their overall stability and ensure secure installation. While these crossbeams significantly improve the stability of the battery pack system, this arrangement also increases the complexity and workload of the battery pack installation process, placing higher demands on the efficiency and ease of operation for the workers.

[0030] The auxiliary fixing mechanism 3 consists of multiple crossbeams 31, side plate 1 32, and side plate 2 33. The multiple crossbeams 31 are divided into a top crossbeam 311, a middle crossbeam 312, and a bottom crossbeam 313. The top crossbeam 311, the middle crossbeam 312, and the bottom crossbeam 313 are arranged vertically and equidistantly in sequence. The bottom crossbeam 313 is fixedly connected to the inner wall of the shell 1. Each adjacent crossbeam is hinged to side plate 1 32 and side plate 2 33 respectively. Side plate 1 32 and side plate 2 33 are hinged together by a pivot.

[0031] During the process of fixing the battery pack inside the housing 1, the operator pulls the top crossbeam 311 downwards. During this process, side plates 32 and 33, based on their hinged structure, fold together, reducing the distance between the crossbeams. This structural change creates a larger installation space inside the housing 1, providing more ample working area for the operator, effectively reducing installation difficulty, and significantly improving the battery pack installation efficiency.

[0032] The top crossbeam 311 is provided with a hand buckle 34, and the housing 1 is provided with a locking assembly for locking the hand buckle 34; the locking assembly includes: a mounting base 351 fixedly installed on the housing 1, a handle 352 hinged to the mounting base 351, and a hook 353 hinged to one end of the handle 352.

[0033] After the battery pack is fixedly installed inside the housing 1, the operator only needs to manually pull the handle 34 upwards. Under the transmission of force, the top crossbeam 311 will move synchronously with the movement of the handle 34. Since the side plates 32 and 33 are hinged to the crossbeam, during the movement of the crossbeam, the side plates 32 and 33 will successively deflect outwards until they are perpendicular to the crossbeam. At this time, the middle crossbeam 312 is precisely abutting between the two adjacent battery packs, providing effective support for the battery pack and effectively preventing the battery pack from loosening on the bracket due to vibration during vehicle operation. When the handle 34 moves to the end of its travel in this direction, the operator hooks the handle 34 onto the hook 353 to fix and limit the handle 34, ensuring the stability of the support structure. When it is necessary to fold the crossbeam, the operator holds the handle 352 and rotates it around the hinge point to easily release the hook from the hook 353.

[0034] It is important to emphasize that both side plate 32 and side plate 33 are provided with heat dissipation holes 37. When the crossbeam is in the extended state, it provides lateral support to the battery pack. At this time, airflow channels are naturally formed between adjacent crossbeams and between the crossbeam and the side plate. After the battery pack is put into operation, the heat generated during its operation flows into the aforementioned airflow channels through the heat dissipation holes 37 on the side plate. This heat is effectively dissipated to the outside of the housing 1 by the airflow within the airflow channels, thereby significantly improving the heat dissipation efficiency of the battery pack. Thus, through the design of the crossbeam: on the one hand, it provides reliable lateral support for the battery pack, ensuring the installation stability of the battery pack within the housing 1; on the other hand, the airflow channels formed when the crossbeam is extended can promptly dissipate the heat generated by the battery pack, effectively improving the practicality and reliability of the entire device.

[0035] The top crossbeam 311 is also provided with a fixing component for fixing the wire harness; the fixing component includes: a snap-fit ​​block 361 fixedly installed on the top crossbeam 311, the snap-fit ​​block 361 is provided with a snap-fit ​​groove 362, the snap-fit ​​groove 362 is provided with a sliding groove 363, and a stop block 364 is slidably installed in the sliding groove 363; the stop block 364 and the sliding groove 363 are elastically connected by a return spring 365.

[0036] When the top crossbeam 311 moves to its top limit position, the operator needs to organize and secure the wiring harness on the battery pack. Specifically, the wiring harness is snapped into the snap-in slot 362 on the snap-in block 361. It is important to emphasize that the operator only needs to manually push the wiring harness into the snap-in slot 362. At this time, the abutment block 364, which is slidably installed in the sliding groove 363, will slide inward along the sliding groove 363 under the pressure applied by the wiring harness, thereby releasing the constraint on the entrance of the snap-in slot 362 and allowing the wiring harness to enter the snap-in slot 362 smoothly and conveniently. After the wiring harness is fully inside the snap-in slot 362, the spring preset in the sliding groove 363 will generate elastic restoring force, pushing the abutment block 364 to reset, thus limiting the wiring harness and achieving a neat and orderly fixation of the battery pack wiring harness, thereby ensuring the standardization and safety of the wiring harness arrangement.

[0037] The inner and outer sides of the housing 1 (battery pack bracket) are respectively provided with reinforcing ribs 38, and the inner and outer reinforcing ribs 38 are staggered. When the battery pack bracket is subjected to a variety of complex external forces such as battery weight, vehicle driving vibration and accidental collision, stress is prone to concentrate in local areas. The staggered reinforcing ribs 38 can break the uniformity of stress distribution, so that the stress is more evenly distributed in different positions, avoiding excessive accumulation of stress at a certain point or in a certain area, thereby effectively improving the overall structural strength of the bracket and reducing the risk of structural damage caused by stress concentration.

[0038] Working Principle: During the process of fixing the battery pack inside the housing 1, the operator pulls the top crossbeam 311 downwards. Side plates 32 and 33 fold together, reducing the distance between the crossbeams and providing more work space. After the battery pack is fixed in the housing 1, the operator pulls the handle 34 upwards. Under the transmission of force, the top crossbeam 311 moves synchronously with the handle 34. Because side plates 32 and 33 are hinged to the crossbeam, they deflect outwards during the movement until they are perpendicular to the crossbeam. At this point, the middle crossbeam 312 abuts between two adjacent battery packs, providing effective support and preventing the battery pack from loosening due to vibrations during vehicle operation.
