Description

Technical Field

[0001] The utility model relates to the field of transportation protection structures, and more specifically, to a quick-disassembly anti-collision structure for transportation. Background Art

[0002] As the world's largest producer of energy storage batteries, energy storage battery companies have a large number of battery transportation needs. At present, the applicant uses the form of direct delivery of energy storage containers for transportation. By directly building electrical connection components - fire pipes and devices into standard-sized containers, it is compatible with the current international mainstream container specifications, and can be used "out of the box". It only needs to connect external lines to be activated. Since this type of energy storage container is compatible with existing container specifications, it can use existing ships and transport vehicles during shipping and land transportation, thereby achieving the purpose of saving space to the greatest extent.

[0003] Based on the above purpose, the components in the existing energy storage containers have more active components than those in conventional battery clusters that are transported in categories. During transportation, the internal active components may also move due to external influences. In order to avoid the movement or detachment of active components, which may damage the battery pack and cause fire accidents, the present application aims to provide a quick-detachable anti-collision structure for transportation, which can realize the rapid installation of the anti-collision structure before transportation and the rapid removal of the anti-collision structure during the deployment process after transportation, thereby reducing deployment costs. Summary of the invention

[0004] The utility model overcomes the shortcomings of existing energy storage containers in that movable parts may damage battery packs during transportation, causing battery pack failure or even fire accidents, and provides a quick-detachable anti-collision structure for transportation, which can realize rapid installation of the anti-collision structure before transportation and rapid release of the anti-collision structure during deployment after transportation, thereby reducing deployment costs.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A quick-detachable anti-collision structure for transportation comprises a mounting frame and an anti-collision plate, wherein the mounting frame comprises a frame body for placing a battery pack, the battery pack and a latch assembly, a side wall of a bottom bracket of the battery pack is provided with a plurality of latch holes, the latch assembly comprises a latch rod and a plurality of latch pins on the latch rod, a mounting guide rail is provided on the upper side wall of the frame body, and a plurality of limit holes are provided on the mounting guide rail; the latch assembly further comprises a telescopic adjustment rod, a transmission joint and a linkage rod, and the rotation of the telescopic adjustment rod drives the latch rod to approach the battery pack so that the latch pin passes through the limit hole and is inserted into the latch hole;

[0007] Both ends of one end of the latch rod are detachably connected with movable latches, and end surfaces on the left and right sides of the anti-collision plate are provided with anti-collision holes, and the movable latches are inserted into the anti-collision holes.

[0008] The latch assembly is used to connect the battery pack and the frame body as one. In addition to positioning the battery pack, the frame body also has a battery management system placed at the bottom, which manages each battery pack in the battery cluster. The frame body includes 4 beams, and there is a mounting rail between the beams in the front direction. The battery pack is supported on the mounting rail. There are several latch holes on the side wall of the bottom bracket of the battery pack, and there are also limit holes on the mounting rail. When the latch passes through the limit hole and is inserted into the latch hole, the mounting rail can be positioned. The latch adopts a quick release form. It is connected in the form of a latch rod. It only needs to push the latch rod toward the battery pack, and several latches corresponding to the battery pack can be inserted at the same time to achieve positioning. For multiple battery packs, the quick release structure of the present application adopts a telescopic adjustment rod and a transmission rod to realize the conversion of the rotation of the telescopic adjustment rod into the translation of the linkage rod through the transmission joint, and the simultaneous driving of multiple latch rods is realized through the connection of the linkage rod and the latch rod. In this way, only the telescopic adjustment rod needs to be rotated to realize the connection of all battery packs and the frame body by the latch assembly on one side. The movable latch is used to position the anti-collision plate, so that the displacement of the movable parts during transportation will not directly contact the battery pack. The above connection method makes it easier to disassemble and install the anti-collision plate.

[0009] Preferably, the transmission joint has two rotating holes that are vertical and not on the same plane, the telescopic adjustment rod is provided with an eccentric segment, the eccentric segment is inserted into one rotating hole and is rotatably connected to the rotating hole, the linkage rod is inserted into another rotating hole and is rotatably connected to the rotating hole, and at least two rings are provided on the latch rod, and the rings of the latch rod corresponding to each battery pack are sleeved on the linkage rod. The above structure is used to ensure that the latch is fully inserted into the latch hole to ensure that it abuts the bottom of the latch hole. Specifically, by rotating the telescopic adjustment rod, the eccentric segment can be rotated around the corresponding rotating hole, thereby further moving in the axial direction on the premise that the latch has been partially inserted into the latch hole. In conjunction with the transmission joint and the linkage rod, the rotation of a telescopic adjustment rod can drive the synchronous movement of each latch rod, thereby accelerating the locking and unlocking steps.

[0010] Preferably, the anti-collision plate is fitted with the beam member constituting the mounting frame and has a gap between the anti-collision plate and the battery pack. The above structure enables the anti-collision plate to be supported by the mounting frame, avoiding stress concentration on the active latch, which may break the active latch when subjected to excessive external force. The gap between the anti-collision plate and the battery pack prevents external force from being transmitted to the battery pack through the fitted anti-collision plate, causing damage to the battery pack.

[0011] Preferably, the movable latch is in an "L" shape, and the movable latch is sleeved on the end of the latch rod. The above-mentioned disassembly method is conducive to disassembly of the movable latch after arriving at the transportation destination.

[0012] Preferably, a positioning flange is provided at the bottom of the mounting frame, and a positioning groove for positioning the anti-collision plate is provided between the positioning flange and the beam of the mounting frame. The positioning flange is used to position the anti-collision plate and assist in the installation and removal of the anti-collision plate.

[0013] Preferably, the anti-collision plate is a hollow plate body. Said structure can better absorb energy.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The battery pack is positioned using the existing latch assembly, so that the anti-collision structure can be quickly installed before transportation and quickly removed during deployment after transportation, thereby reducing deployment costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The transmission section 11 has two vertical rotating holes 14 that are not on the same plane. The telescopic adjustment rod 10 is provided with an eccentric section 15. The eccentric section 15 is inserted into one rotating hole 14 and is rotatably connected to the rotating hole 14. The linkage rod 12 is inserted into another rotating hole 14 and is rotatably connected to the rotating hole 14. At least two rings are provided on the latch rod 6. The rings of the latch rod 6 corresponding to each battery pack 3 are sleeved on the linkage rod 12. The above structure is used to ensure that the latch is fully inserted into the latch hole 5 to ensure that it abuts the bottom of the latch hole 5. Specifically, by rotating the telescopic adjustment rod 10, the eccentric section 15 can be rotated around the corresponding rotating hole 14, so that the latch 7 can be further moved in the axial direction on the premise that it has been partially inserted into the latch hole 5. In conjunction with the transmission section 11 and the linkage rod 12, the rotation of a telescopic adjustment rod 10 can drive each latch rod 6 to move synchronously, thereby accelerating the locking and unlocking steps.

[0027] The latch assembly is used to connect the battery pack 3 and the frame body as one. In addition to positioning the battery pack 3, the frame body also has a battery management system placed at the bottom, which manages each battery pack 3 in the battery cluster. The frame body includes 4 beams, and there is a mounting rail 8 between the beams in the front direction. The battery pack 3 is supported on the mounting rail 8. A number of latch holes 5 are provided on the side wall of the base 4 of the battery pack 3, and the mounting rail 8 also has a limiting hole 9. When the latch 7 passes through the limiting hole 9 and is inserted into the latch hole 5, the mounting rail 8 can be positioned. The latch adopts a quick release form. It is connected in the form of a latch rod 6. It only needs to push the latch rod 6 toward the battery pack 3, and a number of latches corresponding to the battery pack 3 can be inserted at the same time to achieve positioning. For multiple battery packs 3, the quick-release structure of the present application adopts a telescopic adjustment rod 10 and a transmission rod to realize the conversion of the rotation of the telescopic adjustment rod 10 into the translation of the linkage rod 12 through the transmission joint 11, and realizes the simultaneous driving of multiple latch rods 6 through the connection between the linkage rod 12 and the latch rod 6. In this way, only the telescopic adjustment rod 10 needs to be rotated to realize the connection of the latch assembly on one side to all the battery packs 3 and the frame body.

The anti-collision plate 2 is fitted with the beam member constituting the mounting frame 1 and a gap is provided between the anti-collision plate 2 and the battery pack 3. The above structure enables the anti-collision plate 2 to obtain support from the mounting frame 1, avoiding stress from being completely concentrated on the movable latch 17, and breaking the movable latch 17 when subjected to excessive external force. The gap between the anti-collision plate 2 and the battery pack 3 prevents external force from being transmitted to the battery pack 3 through the fitted anti-collision plate 2, causing damage to the battery pack 3. The anti-collision plate 2 is a hollow plate body. The structure can absorb energy better. The movable latch 17 is used to position the anti-collision plate 2, thereby positioning the anti-collision plate 2, so that the displacement of the movable parts during transportation will not directly contact the battery pack 3. The aforementioned connection method makes the disassembly and assembly of the anti-collision plate 2 relatively simple and convenient.

[0029] In some embodiments, the movable latch 17 is in an "L" shape, and the movable latch 17 is sleeved on the end of the latch rod 6. The above-mentioned disassembly method is conducive to disassembling the movable latch 17 after arriving at the transportation destination. A positioning flange 16 is provided at the bottom of the mounting frame 1, and a positioning groove for positioning the anti-collision plate 2 is provided between the positioning flange 16 and the beam of the mounting frame 1. The positioning flange 16 is used to position the anti-collision plate 2 to assist in the installation and removal of the anti-collision plate 2.
