[0033] In order for those skilled in the art to better understand the utility model scheme, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings.

[0034] It should be noted that the embodiments in the utility model and the features and technical schemes in the embodiments can be combined with each other without conflict.

[0035] It should be noted that: similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0036] Embodiment 1, please refer to Figures 1-5 A battery pack mounting structure, comprising a box beam 1, the side of the box beam 1 is provided with a mounting table 3, the mounting table 3 is provided with a concave sliding groove 6, one side of the mounting table 3 is provided with an upper sliding groove hole 5 in communication with the concave sliding groove 6, the concave sliding groove 6 is provided with a detachable nut plate 7, and the nut plate 7 is provided with a plurality of mounting nut holes 11, and the bottom of the nut plate 7 is provided with a plurality of welding nuts 8; the application is through setting up the box beam 1 and the welding nut 8 separately, and transition through the nut plate 7, and the sliding adjustment of the fixed installation of the nut plate 7 can be realized through the upper sliding groove hole 5, for the battery pack box body structure under the same platform, the along use of large parts can be realized, the generalization rate is improved, the development cost is reduced, and the efficiency is improved; for the battery pack box body structure of different platforms, only by changing the hole position, length and shortness of the small parts such as the nut plate 7, the large parts such as the box beam 1 are not changed, and the generalization rate is improved, the development cost is reduced, and the efficiency is improved.

[0037] Further, as Figure 1 , Figure 3 and Figure 5As shown, the positions of the plurality of welding nuts 8 correspond to the positions of the plurality of mounting nut holes 11 respectively, so that the battery pack mounting screws can pass through the mounting nut holes 11 and be connected with the welding nuts 8; the positions of the welding nuts 8 and the mounting nut holes 11 correspond accurately, which provides a precise connection basis for the battery pack mounting, not only makes the installation process extremely smooth, reduces the time of installation workers to find and adjust, improves the installation efficiency, but also effectively reduces the installation error caused by the deviation of the welding nuts 8 and the mounting nut holes 11, and ensures the firmness and stability of the battery pack installation.

[0038] Further, the upper sliding groove hole 5 is used for the battery pack mounting bolt to pass through, so as to realize the connection of the battery pack mounting bolt and the welding nut 8. The upper sliding groove hole 5 serves as a dedicated channel for the battery pack mounting bolt, and plays a key role in connecting the battery pack and the welding nut 8. The reasonable design of the upper sliding groove hole 5 ensures that the battery pack mounting bolt can be connected with the welding nut 8, so that the battery pack installation process can be carried out in an orderly manner.

[0039] Further, as shown in Figures 1-4 , the concave sliding groove 6 is provided with a limiting table 10, one side of the limiting table 10 being in contact with the nut plate 7.

[0040] Further, the limiting table 10 is used for supporting the nut plate 7, so as to provide a supporting platform for the nut plate 7 before use.

[0041] Further, as shown in Figures 1-2 , the limiting table 10 is provided with a lower sliding groove hole 9, the size of the lower sliding groove hole 9 being matched with the size of the welding nut 8. The lower sliding groove hole 9 is used for avoiding the welding nut 8, so as to reduce the interference between the welding nut 8 and the limiting table 10. This makes the nut plate 7 be able to slide freely and smoothly in the concave sliding groove 6, greatly improving the convenience and efficiency of the assembly process.

[0042] In embodiment 2, the battery pack mounting structure provided in embodiment 1 is further optimized. Specifically, as shown in Figure 4 , the outer surfaces of the box beam 1, the mounting table 3 and the nut plate 7 are provided with protective coatings. The protective coatings can effectively prevent harmful substances in the outside world from directly contacting the surfaces of the box beam 1, the mounting table 3 and the nut plate 7, reduce the occurrence of corrosion, maintain the original accuracy and structural integrity of the components, prolong the service life of the components, reduce the replacement demand caused by corrosion and wear, and the protective coatings can adopt epoxy resin coatings.

[0043] Further, the opening edge of the concave chute 6 is provided with a chamfer to facilitate the insertion of the nut plate 7, and the smooth insertion process can also reduce scratches and damage to the edges of the nut plate 7 and the concave chute 6 caused by forced insertion, thereby protecting the surface quality of the components, reducing the risk of potential failure caused by damage to the surface of the components, and improving the assembly quality and overall reliability of the product.

[0044] In embodiment 3, the nut plate 7 is further optimized for the battery pack mounting structure provided in embodiment 1 or 2, and specifically, the side of the nut plate 7 away from the mounting nut hole 11 is provided with roughness, which cleverly utilizes the principle of friction to add a reliable guarantee for the stability of the nut plate 7 in the concave chute 6 during use, and can effectively prevent unnecessary sliding or displacement of the nut plate 7.

[0045] Further, as shown in Figures 1-2 , the mounting table 3, the box beam 1 and the limiting table 10 are integrally arranged to increase the stability of the overall structure, so that the application can better withstand the weight of the battery pack and various complex external forces generated during vehicle operation, such as acceleration, deceleration, turning, jolting, etc. When facing high-strength external forces, the integral structure can evenly disperse stress, reduce component damage or structural deformation caused by local stress concentration, thereby ensuring the long-term stability and reliability of the battery pack installation.

[0046] The use process of the battery pack mounting structure provided by the utility model is as follows:

[0047] The battery pack is carried on the top of the mounting table 3, the nut plate 7 is moved to align the welding nut 8 with the battery pack mounting bolt, the battery pack mounting bolt is passed through the mounting hole on the battery pack, the battery pack mounting bolt is then passed through the mounting nut hole 11 and connected together with the welding nut 8, and the nut plate 7 is moved upward according to the position relationship shown in Figure 1 to contact and fix the top of the inner cavity of the concave chute 6, that is, the installation of the battery pack is completed, and for different models of battery packs, only the nut plate 7 and the welding nut 8 need to be replaced.
