Description

Technical Field

[0001] The present invention relates to the technical field of integrated energy storage cabinet transportation, and in particular to an integrated energy storage cabinet battery connector. Background Art

[0002] Energy storage cabinets are a common facility in power systems. They store energy through multiple groups of batteries inside. They have a wide range of applications. Current energy storage cabinets are often split. They often need to be disassembled for transportation. After they arrive at the destination, they are installed by technicians. This is costly. The current integrated energy storage cabinets need to fix the batteries during transportation, but the batteries cannot be directly fixed in the energy storage cabinet rack. Otherwise, it is easy to cause bumps and damage to the batteries during transportation. Currently, they are fixed after adding flexible rubber foot pads. This method causes the batteries to shake within a certain range during transportation. However, the batteries placed on the upper floors of the energy storage cabinet will have a greater displacement when the cabinet body is offset at the same angle. Currently, fillers are placed to assist in reducing the displacement of the batteries during transportation. If the fillers are not cleaned after transportation, the heat dissipation of the batteries will be seriously affected. In particular, air-cooled energy storage cabinets have a lower heat dissipation efficiency than liquid-cooled energy storage cabinets, so they are more afraid of missing fillers. This also leads to the use of a large number of fillers, which can easily cause damage to the energy storage cabinet due to unclean filler cleaning.

[0003] At present, the connection of batteries in energy storage cabinets is through series connection of wires. Similarly, batteries placed at high levels require longer wires due to their large displacement. In order to avoid insufficient wire length, the current integrated energy storage cabinets will uniformly use longer wires to connect the batteries at each level. However, when the cabinet reaches the destination and is used normally, due to redundant wires, it is easy to get entangled, damaged and unsightly, which can easily lead to safety problems. At present, there is a need for a battery connection component that can help reduce the displacement distance of high-level batteries, thereby reducing the use of fillers, and deal with the above wire-related problems.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 11 As shown, an integrated energy storage cabinet battery connector includes a connecting part, one end of the connecting part is connected to the battery of the energy storage cabinet, the other end of the connecting part is provided with a trigger part, the end of the trigger part is provided with a telescopic control part, the middle of the telescopic control part is provided with a slide groove, and the slide groove is provided with an auxiliary fixing part. The auxiliary fixing part can assist the installation of the device through the evenly arranged holes reserved in the energy storage cabinet and assist in fixing the battery pack.

[0030] The connecting portion includes a holding portion 12, to which a suspension screw 11 is rotatably connected, to which a connecting head 10 is fixedly connected, and an external thread is arranged on the outside of the connecting head 10. The connecting head 10 is connected to a threaded hole of the battery pack, thereby maintaining electrical connection with the battery pack.

[0031] The trigger part includes a special-shaped trigger conductor 13 fixedly connected to the gripping part 12, a trigger protection plate 14 is fixedly connected to the end of the special-shaped trigger conductor 13, a trigger seat 16 is slidably connected to the special-shaped trigger conductor 13, a trigger mechanism is arranged at the bottom of the trigger seat 16, the trigger mechanism includes a trigger button 30, the trigger button 30 is in contact with the special-shaped trigger conductor 13, mounting seats 15 are fixedly connected to both sides of the trigger seat 16, the middle part of the mounting seat 15 is rotatably connected to the limit rotating shaft 17 through a rotating shaft and a torsion spring, a telescopic control part is arranged on the limit rotating shaft 17, and the trigger mechanism also includes a limit rod 32, which initially extends into the corresponding opening of the limit rotating shaft 17. When the position of the battery in the integrated energy storage cabinet changes significantly during transportation, the position of the special-shaped trigger conductor 13 in the trigger seat 16 will change, thereby triggering the trigger mechanism and disengaging the limit rod 32 from the limit rotating shaft 17, so that the trigger seat 16 can rotate around the limit rotating shaft 17 to unload the force, thereby avoiding damage to the battery pack connection end due to strong squeezing through the connection part. When the transportation is stable, the battery pack will reset under the action of the bottom rubber pad and the torsion spring. At this time, the trigger mechanism resets, and then continues to provide auxiliary protection for the battery pack that shakes slightly during transportation.

[0032] The trigger mechanism includes a trigger button 30 slidably connected to the bottom cavity of the trigger part, a limiting seat 36 is fixedly connected to the bottom of the cavity, the middle of the limiting seat 36 is penetrated and slidably connected to the limiting rod 32, and the two sides of the limiting seat 36 are penetrated and slidably connected to the middle movable block 31 in the shape of a "Z", the left and right ends of the middle movable block 31 have inclined surfaces parallel to each other, the inclined surfaces are slidably connected to the push block 33, the push block 33 is fixedly connected to the inner end surface of the trigger button 30, an oblique through groove is provided in the middle of the limiting rod 32, and the inclination degree of the through groove is the same as the inclination degree of the middle of the middle movable block 31, that is, they are arranged in parallel, the upper end of the limiting rod 32 is fixedly connected to the reset spring mounting seat 35, and the upper end of the reset spring mounting seat 35 is fixedly connected to the limit rod reset spring 34 The upper end of the limit rod reset spring 34 is fixedly connected to the inner wall of the trigger button 30, and the lower end of the limit rod 32 is deep outside the trigger seat 16 and the extended end is snapped into the corresponding slot at the upper end of the limit rotating shaft 17; when the trigger button 30 is pressed down, the limit rod reset spring 34 will be compressed and the push block 33 will push the middle movable block 31 to move laterally under the restriction of the transverse groove of the limit seat 36. During this process, the middle inclined section of the middle movable block 31 will change position with the middle inclined section of the limit rod 32, and the contact position will move to the left, while the middle movable block 31 of the left section is higher, and the limit rod 32 can only move in the up and down directions under the restriction of the longitudinal through hole of the limit seat 36, thereby moving the limit rod 32 upward, and then separating the limit rod 32 from the limit rotating shaft 17.

[0033] The telescopic control part includes an end telescopic rail 18, which is strip-shaped and has a slide groove in the middle. An electromagnetic clutch mechanism is slidably connected in the slide groove. The other end of the electromagnetic clutch mechanism is slidably connected in the slide groove in the middle of the middle movable rail 20. The middle movable rail 20 is slidably connected in the middle fixed rail 19. The connection methods of the parts at both ends of the middle fixed rail 19 are the same and symmetrically arranged, which will not be repeated here. When the trigger part is triggered, the electromagnetic clutch mechanism will be driven by the sensor to loosen the connection between the middle movable rail 20 and the end telescopic rail 18. At this time, the angle and position relationship between the end telescopic rail 18 and the middle fixed rail 19 can change, so as to adapt to the movement of the connecting part to ensure that the connecting end of the battery pack will not be damaged due to lack of freedom during large shaking.

[0034] The electromagnetic clutch mechanism includes a fixed clamping piece 24, on the end surface of which a plurality of electromagnets 25 fixedly connected thereto are distributed in an annular manner, and a protective cover (not shown in the figure) is also installed on the electromagnet 25, and one side of the electromagnet 25 is slidably installed in the end telescopic rail 18, a guide column 26 is fixedly connected to the middle of the fixed clamping piece 24, and a clamping protection plate 23 is fixedly connected to the end of the guide column 26, and a movable clamping piece 27 is slidably connected to the middle of the guide column 26, and a permanent magnet is arranged on the movable clamping piece 27, and a clamping groove is evenly distributed on the outer end surface of the guide column 26, and an electromagnet 25 is fixedly connected to the bottom of the limiting groove, and a limiting tooth 28 is slidably connected in the clamping groove, and a permanent magnet is fixedly arranged at the bottom of the limiting tooth 28 , so that it can be controlled by the electromagnet 25 to complete the retraction; when the end telescopic rail 18 and the middle movable rail 20 are in a fixed state, the upper end of the movable clamping piece 27 is located at the lower end of the limiting tooth 28 and is stuck. At this time, the fixed clamping piece 24 and the movable clamping piece 27 complete the clamping of the end telescopic rail 18 and the middle movable rail 20. At this time, the relative positions of the end telescopic rail 18 and the middle movable rail 20 are fixed. When the relative position relationship of the end telescopic rail 18 and the middle movable rail 20 changes when necessary, the control electromagnet 25 and the electromagnet 25 at the bottom of the limiting groove work to make the limiting tooth 28 retract, and the electromagnet 25 pushes the movable clamping piece 27 to move it to the other end, thereby canceling the relative position fixation.

[0035] The auxiliary fixing part includes a telescopic control part, which includes a middle fixed rail 19. The fixing seat 29 of the auxiliary fixing part is rotatably connected to the middle fixed rail 19. A threaded through hole is provided in the middle of the fixing seat 29, and a truncated cone column 22 is threadedly connected in the threaded through hole. The protruding end of the truncated cone column 22 is a truncated cone shape with a large outside and a small inside. A plurality of extrusion sheets 21 are distributed in a ring shape with the threaded hole as the central axis on the end surface of the fixing seat 29 and the truncated cone column 22 on the same side; before transportation, the extrusion sheet 21 is extended into the evenly arranged hole positions reserved on the shelf of the energy storage cabinet, and the truncated cone column 22 is twisted by a tool to make its truncated cone end close to the fixing seat 29. At this time, the large end of the truncated cone column 22 will push the extrusion sheet 21 to expand outward, so that the extrusion sheet 21 is squeezed with the through hole wall, thereby playing the role of a fixing device.

[0036] The special-shaped trigger conductor 13 of the trigger part is in the shape of a funnel with large ends and a small middle, thereby ensuring that the above work can be completed even if the battery pack moves in another direction.

[0037] In each component between the two connecting parts of the connector, a conductor carbon film is laid at a contactable position or a conductive material is directly used, and an insulating material is wrapped or sprayed on the outside or the connector itself is directly composed of an insulating material to ensure the safety of power transmission.

[0038] Working principle of the present invention:

[0039] Before transportation, the extrusion sheet 21 is inserted into the evenly arranged holes reserved on the shelf of the energy storage cabinet, and the cone column 22 is screwed by a tool to make its cone end close to the fixing seat 29. At this time, the large end of the cone column 22 will push the extrusion sheet 21 to expand outward, so that the extrusion sheet 21 is squeezed against the through hole wall, thereby playing the role of a fixing device; the connector 10 is connected to the threaded hole of the battery pack, so as to maintain electrical connection with the battery pack. When the battery position of the integrated energy storage cabinet changes significantly during transportation, the position of the special-shaped trigger conductor 13 in the trigger seat 16 will change, so that the trigger mechanism is triggered, and the limit rod 32 is separated from the limit rotating shaft 17, so that the trigger seat 16 can rotate with the limit rotating shaft 17 as the axis to unload the force, thereby avoiding damage to the battery pack connection end due to strong squeezing through the connection part. When the transportation is stable, the battery pack will be reset under the action of the bottom rubber pad and the torsion spring. At this time, the trigger mechanism is reset, and then continues to provide auxiliary protection for the battery pack that shakes slightly during transportation.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
