[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of an integrated rapid assembly device for battery pack trays, comprising a tray 1. The tray 1 is the main load-bearing structure of the integrated rapid assembly device for battery packs. The tray 1 is used to support the battery packs 9, the positioning mechanism, and the locking mechanism, and provides support and connection. The bottom of the tray 1 is fixedly connected to the positioning mechanism, which is used to fix and accurately position the battery packs 9 and the battery module shells 12 on the tray 1, ensuring that the battery packs 9 can be accurately aligned and fixed during the assembly process. The inside of the tray 1 is slidably connected to the locking mechanism, which is used to ensure that the battery packs 9 are fixed in the tray 1 and prevent them from loosening during transportation or assembly. Six battery packs 9 are slidably connected inside the tray 1. The battery packs 9 are the core components of the tray 1 assembly system. The battery packs 9 are installed in the tray 1 through the positioning mechanism and the locking mechanism, ensuring that they will not shift or be disturbed by external factors during transportation.

[0026] The locking mechanism includes two sliding armrests 5, which can slide within the tray 1 to facilitate locking and unlocking of the battery pack 9. The two sliding armrests 5 are externally slidably connected to the inside of the tray 1. Three locking blocks 6 are fixedly connected to the adjacent side of the two sliding armrests 5. The locking blocks 6 can slide to the inside of the battery pack 9 to ensure that the battery pack 9 is accurately locked in the tray 1. The three locking blocks 6 are externally slidably connected to the inside of the battery pack 9. An auxiliary component is slidably connected to the inside of the tray 1. An armrest groove is provided at the bottom of the side of the sliding armrest 5 that is far from the tray 1. The tray 1 has an empty groove at the bottom of the armrest groove. A sliding groove is provided inside the tray 1. The outside of the sliding armrest 5 is slidably connected to the inside of the sliding groove. Guide grooves are provided on the upper and lower sides of the sliding groove. Guide blocks are provided on the upper and lower sides of the sliding armrest 5. The guide blocks are slidably connected to the inside of the guide groove.

[0027] The auxiliary components include multiple auxiliary blocks 7, which provide additional fixed support for the battery pack 9, ensuring the stability of the battery pack 9 during transportation and assembly. The external parts of the multiple auxiliary blocks 7 are slidably connected to the inside of the tray 1, and the tops of the multiple auxiliary blocks 7 are slidably connected to the inside of the locking block 6. The bottom of each auxiliary block 7 is fixedly connected to a movable spring 8, which ensures that the auxiliary block 7 can be held in a predetermined position and provides the necessary power and support for the assembly process. The auxiliary blocks 7, in conjunction with the movable springs, ensure that the battery pack 9 can quickly and accurately enter the correct position and be firmly locked during installation. The other ends of the multiple movable springs 8 are fixedly connected to the inside of the tray 1. The inside of the tray 1 has multiple mounting slots, and the external parts of the multiple auxiliary blocks 7 are slidably connected to the inside of the mounting slots. The external parts of the battery pack 9 have four fixing slots, and the locking block 6 and the auxiliary blocks 7 are slidably connected to the inside of the fixing slots. The top of the auxiliary blocks 7 has a ramp design, which is opposite to the handrail slot at the bottom of the sliding handrail 5.

[0028] Reference Figures 2 to 4 The positioning mechanism includes four short positioning blocks 3. The main function of the short positioning blocks 3 is to provide stable lateral positioning for the battery pack 9, so as to avoid the battery pack 9 from shifting or misaligning during assembly. The adjacent sides of the four short positioning blocks 3 are fixedly connected to the left and right sides of the tray 1, respectively. Two long positioning blocks 2 are fixedly connected to the front and rear sides of the tray 1, respectively. The long positioning blocks 2 are used to adjust the position of the battery pack 9 more accurately, to ensure the precise positioning of the battery pack 9 in the longitudinal direction, and to prevent excessive movement or misalignment. Protective rings 4 are fixedly connected inside the four short positioning blocks 3 and the two long positioning blocks 2. The protective rings 4 prevent the influence of external collisions or other external forces on the positioning mechanism, and ensure that the positioning mechanism is in a stable and protected state during use.

[0029] Two long positioning blocks 2 are slidably connected to a battery module housing 12 on one side. The battery module housing 12 is the external structure used to accommodate and protect the battery pack 9. A module base 13 is fixedly connected to the bottom of the battery module housing 12. Four partition plates 10 are fixedly connected inside the battery module housing 12. A main partition plate 11 is fixedly connected inside the battery module housing 12. The partition plates 10 and the main partition plate 11 are used to separate the battery pack 9, which increases the stability of the battery pack 9 and facilitates the smooth sliding of the battery pack 9 during assembly. The four partition plates 10 and the main partition plate 11 form six squares. The outside of the battery pack 9 is slidably connected inside the squares.

[0030] Working principle: Multiple battery packs 9 are placed one by one inside the tray 1. During the process of placing the battery packs 9 into the tray 1, the side walls of the battery packs 9 will press the inclined surface of the auxiliary block 7, causing the auxiliary block 7 to press the movable spring 8. When the battery packs 9 are completely placed inside the tray 1, the fixing grooves opened on the outside of the battery packs 9 correspond to the auxiliary block 7. At this time, the side walls of the battery packs 9 do not contact the auxiliary block 7. The movable spring 8 loses its limit and then releases elastic potential energy to push the auxiliary block 7 into the fixing groove, thereby limiting the battery packs 9. Then, the sliding handle 5 is pushed. With the assistance of the sliding groove and guide groove inside the tray 1, the locking block 6 on the adjacent side of the two sliding handles 5 is also slidably connected inside the fixing groove, further improving the stability of the battery packs 9. Then, the tray 1 is flipped over. The handle groove at the bottom of the sliding handle 5 provides convenience for moving the tray 1. And because the tray 1 can accommodate six battery packs 9, the handling efficiency of the battery packs 9 is improved.

[0031] When placing the battery pack 9 into the battery module housing 12, first flip the tray 1 so that the four short positioning blocks 3 and two long positioning blocks 2 at the bottom of the tray 1 fit into the battery module housing 12, thereby aligning the tray 1 and the battery module housing 12. At the same time, because the placement position of the battery pack 9 inside the tray 1 is consistent with the position of the cavity formed by the partition plate 10 and the main partition plate 11 inside the battery module housing 12, pull the sliding handle 5. With the assistance of the sliding groove and the guide groove, the sliding handle 5 drives the locking block 6 to leave the fixing groove inside the battery pack 9. Then, simply press the battery pack 9. Due to the top slope design, the auxiliary block 7 that slides in the fixing groove inside the battery pack 9 gradually slides during the pressing process and eventually leaves the fixing groove inside the battery pack 9, allowing the battery pack 9 to leave the inside of the tray 1 and enter the cavity inside the battery module housing 12, thus completing the assembly of the battery pack 9.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
