Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a battery swapping bracket structure for automotive batteries. Background Technology

[0002] With the increasing popularity of new energy vehicles, consumers have higher and higher requirements for their energy replenishment and range. Energy replenishment methods for new energy vehicles can generally be divided into charging and battery swapping. Currently, the pain points of charging, such as low vehicle-to-pile ratio, difficulty in charging, and long charging time, are becoming increasingly prominent, and fast charging technology causes significant battery wear. Battery swapping, on the other hand, can quickly replenish energy without affecting battery lifespan, offering lower costs, higher efficiency, and better safety, thus gradually gaining an advantage in the market. However, current battery swapping methods are still in the exploratory stage. Standards for battery swapping methods vary greatly among companies, and the types and operations of battery swapping mechanisms are difficult to standardize. Furthermore, most methods require significant modifications to the vehicle's structure, leading to high production costs. Therefore, there is a need to invent a new battery pack swapping bracket structure for automobiles. Utility Model Content

[0023] like Figures 1 to 7The diagram shows a battery pack swapping bracket structure, including a battery bracket 2 fixedly connected to both sides of a battery pack 1. A swapping bracket 3 for fixed connection to the vehicle body is detachably connected to the battery bracket 2. Several sets of swapping locking mechanisms 4 are arranged at intervals in the battery bracket 2. In order to reduce weight, several weight-reducing grooves are provided in both the battery bracket 2 and the swapping bracket 3 along the length of the vehicle body.

[0024] The battery swapping locking mechanism 4 includes a lock box 41, a locking bolt 43, and a floating nut 44. The lock box 41 is fixedly connected to the battery bracket 2. The locking bolt 43 passes through the lock box 41. The floating nut 44 is disposed in the battery swapping bracket 3. The locking bolt 43 and the floating nut 44 are screwed together.

[0025] In order to facilitate the limiting assembly of the battery swapping locking mechanism 4 and reduce the Z-axis assembly height of the battery bracket 2 and the battery swapping bracket 3, the battery bracket 2 is provided with several sets of first fixing slots 21 at intervals, and the lock box 41 is fixedly connected to the first fixing slots 21 by screws.

[0026] In order to facilitate the assembly and fixation of the battery swapping locking mechanism 4 and the battery bracket 2, and to limit the locking bolt 43, a lock box fixing plate 42 is fixedly provided at the lower end of the lock box 41. The lock box fixing plate 42 is fixedly connected to the battery bracket 2 by screwing.

[0027] To prevent the locking bolt 43 from falling downward from the lock box 41 and to limit the height of the locking bolt 43 as it is screwed into the floating nut 44 from bottom to top, a limiting plate 431 is fixedly provided on the side wall of the locking bolt 43; the limiting plate 431 is used to cooperate with the inner top wall of the lock box 41 and the lock box fixing plate 42 at the bottom of the lock box 41 for limiting.

[0028] To facilitate the limiting assembly of the floating nut 44 and the floating nut fixing seat 45, and to reduce the Z-axis height of the battery swapping bracket 3, the battery swapping bracket 3 is provided with several sets of second fixing grooves 31 at intervals, and the floating nut 44 and the floating nut fixing seat 45 are both set in the second fixing grooves 31.

[0029] To better limit the floating nut 44 and prevent it from falling out of the second fixing groove 31, the battery swapping locking mechanism 4 also includes a floating nut fixing seat 45. The floating nut fixing seat 45 is sleeved on the floating nut 44 and is detachably and fixedly connected to the battery swapping bracket 3. The floating nut fixing seat 45 also serves as a dust cover and limits the displacement of the floating nut 44.

[0030] To facilitate assembly with the vehicle body, the battery swapping bracket 3 is fixedly connected to the vehicle body door sill beam by screws.

[0031] To facilitate accurate positioning during vehicle assembly, the battery swapping bracket 3 is provided with several sets of positioning pins 5, which are used to insert into the positioning holes of the vehicle body sill beam.

[0032] When a battery swap is needed, the new battery pack 1 can be positioned and lifted under the car by a robot. The servo gun sleeve of the battery swap station is connected to the toothed spline at the bottom of the locking bolt 43 and rotated clockwise until the limiting plate 431 in the middle of the locking bolt 43 presses against the inner top wall of the lock box 41. At this time, the battery bracket 2 and the battery swap bracket 3 are fastened together and locked.
