Description

Technical Field

[0001] This utility model relates to the field of CTP battery pack disassembly technology, specifically to an auxiliary bracket for disassembling CTP battery packs. Background Technology

[0002] With the booming development of the new energy vehicle industry, CTP (Cell to Pack) battery technology, with its significantly improved volume utilization (15-20% higher than traditional battery packs) and energy density (generally exceeding 180Wh / kg), has become the mainstream design solution for current power battery systems. While this innovative module-free integration technology optimizes the spatial layout and production costs of battery packs, it also brings new engineering challenges: its highly integrated structural design makes the connections between cells, liquid cooling systems, and structural components within the battery pack much tighter, rendering traditional module-based disassembly methods inapplicable. In the maintenance process, technicians face the challenge of accurately locating faulty cells.

[0003] In the traditional CTP battery pack dismantling process, fixed dismantling platforms or large lifting equipment are usually relied upon. These types of equipment are bulky, slow to deploy, and dependent on a stable working environment, making them difficult to adapt to dismantling needs in the field, accident sites, or emergency situations. Especially in electric vehicle accidents, energy storage station failures, or distributed battery recycling scenarios, existing equipment cannot quickly reach and safely and stably fix the battery pack for dismantling. In addition, traditional brackets mostly use metal welded structures, which are heavy, difficult to transport, and take a long time to assemble and debug before dismantling, seriously affecting emergency response efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary support for disassembling CTP battery packs, comprising a base and a lifting platform, an mounting platform above the lifting platform, a first adjusting frame and a second adjusting frame between the base and the lifting platform, the first adjusting frame and the second adjusting frame being arranged in a crisscross pattern, the first adjusting frame and the second adjusting frame being rotatably connected by a rotating rod, a gas spring between the base and the lifting platform, the two ends of the gas spring being rotatably sleeved with the rotating rod and the base respectively, four sets of symmetrically distributed clamping blocks being provided inside the mounting platform, two sets of symmetrically distributed first push rods being slidably installed inside the mounting platform, and two sets of symmetrically distributed second push rods being slidably installed inside the mounting platform.

[0006] As a further preferred embodiment of this technical solution, the right end of the first adjusting frame is rotatably connected to the base via a rotating shaft, the right end of the second adjusting frame is rotatably connected to the lifting platform via a rotating shaft, the left end of the first adjusting frame is rotatably mounted with two sets of symmetrically distributed first sliders, the two sets of first sliders are slidably connected to the lifting platform, and the left end of the second adjusting frame is rotatably mounted with two sets of symmetrically distributed second sliders, the two sets of sliders are slidably connected to the base.

[0007] As a further preferred embodiment of this technical solution, the two sets of first push rods and the two sets of second push rods are vertically distributed. The clamping block is slidably connected to one set of first push rods and the second push rod, respectively. Two sets of symmetrically distributed first bidirectional lead screws are rotatably installed in the mounting platform. Two sets of symmetrically distributed second bidirectional lead screws are rotatably installed in the mounting platform. Sprockets are sleeved on all four sets of first bidirectional lead screws and second bidirectional lead screws. Two sets of vertically distributed drive chains are provided in the mounting platform. The drive chains are respectively connected to the two sets of corresponding sprockets.

[0008] As a further preferred embodiment of this technical solution, the two ends of the two sets of first bidirectional lead screws respectively pass through the two sets of first push rods and are respectively threaded to the two sets of first push rods, and the two ends of the two sets of second bidirectional lead screws respectively pass through the two sets of second push rods and are respectively threaded to the two sets of second push rods.

[0009] As a further preferred embodiment of this technical solution, two sets of cross-distributed brackets are provided between the mounting platform and the lifting platform. Movable blocks are rotatably installed at both ends of the two sets of brackets. The movable blocks are slidably connected to the corresponding mounting platform or lifting platform. Sliding rods are fixedly installed inside the mounting platform and the lifting platform. Damping rods are fixedly installed between the movable blocks and the mounting platform and the lifting platform. A second spring is fitted on the damping rod.

[0010] As a further preferred embodiment of this technical solution, the movable block is slidably sleeved with the slide rod, and two sets of symmetrically distributed first springs are sleeved on the slide rod. The two ends of the two sets of first springs are respectively fixedly connected to the movable block and the mounting platform or lifting platform.

[0011] This utility model provides an auxiliary bracket for disassembling CTP battery packs, which has the following advantages:

[0012] (1) The base and lifting platform of this utility model adopt a composite lifting structure of cross-type adjustment frame and gas spring. It can not only adjust the height of the installation platform to meet the disassembly plane requirements of different battery pack models, but also effectively absorb the vibration and impact during the disassembly process through the damping characteristics of the gas spring. The four-way linkage clamping system integrated in the installation platform realizes the synchronous centering of four sets of clamping blocks through the bidirectional screw and sprocket transmission mechanism. The battery pack can be quickly positioned and rigidly fixed in a short time. Compared with the traditional bolt fixing method, the efficiency is effectively improved. The foldable cross-adjustment frame structure reduces the overall storage volume of the equipment. Combined with aviation aluminum alloy material, the total weight is controlled within a certain range. Two operators can complete the quick handling and unfolding operation. The contact surface between the installation platform and the clamping block is coated with anti-static ceramic coating, which can not only prevent short circuit discharge of high voltage battery pack, but also withstand the instantaneous high temperature of 600℃. It can still be used safely at the scene of electric vehicle fire accident.

[0013] (2) This utility model adopts a cross-type buffer support group and a damping rod and a double spring shock absorption system, which effectively solves the vibration and impact problem during the disassembly process. The two sets of cross supports and the sliding rod guide mechanism form a multi-directional buffer system. With the high-precision damping rod and double springs, the first spring absorbs high-frequency vibration and the second spring buffers low-frequency shaking, which can effectively reduce the impact force generated when the disassembly tool is working. At the same time, the support group is made of high-strength aviation aluminum alloy material. Under the premise of ensuring structural strength, the elastic deformation characteristics of the material can adaptively compensate for slight unevenness in the ground within a certain range, so that the equipment can still maintain stable operation under non-ideal working conditions.
