[0052] The present utility model will be described more specifically by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0053] The following is combined with the specification append Figures 1 to 15 , to introduce the battery module disassembly and assembly tooling of the energy storage system of the present utility model.

[0054] In one of the embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the disassembly and assembly tooling for the energy storage system battery module 500 includes a support frame 100, a lead screw 210, a lead screw nut 220, and a push rod assembly 300. The support frame 100 is used to support the battery module 500; the lead screw 210 is rotatably arranged on the support frame 100, for example, rotatably arranged on the support frame 100 through a bearing; the lead screw nut 220 is in threaded cooperation with the lead screw 210; the push rod assembly 300 is fixedly connected to the lead screw nut 220, and the push rod assembly 300 is slidably arranged on the support frame 100 in a guiding manner, and is used to drive the battery module 500 to move.

[0055] When installing the battery module 500, first place the battery module 500 on the support frame 100, then fixedly connect the push rod assembly 300 to the battery module 500, and use a tool to rotate the lead screw 210, so that the lead screw nut 220 drives the push rod assembly 300 to move in the direction close to the installation position of the battery module 500, then the push rod assembly 300 will drive the battery module 500 to move to the installation position. When disassembling the battery module 500, first use a tool to rotate the lead screw 210 to move the push rod assembly 300 to a position adjacent to the battery module 500, then fixedly connect the battery module 500 to the push rod assembly 300, and then use the tool to rotate the lead screw 210 in the reverse direction to make the push rod assembly 300 pull the battery module 500 onto the support frame 100. The installation and disassembly processes are relatively rapid, with high efficiency, saving manpower and material resources, and reducing safety risks.

[0056] In one embodiment, as Figure 3 shown, the disassembly and assembly tooling for the energy storage system battery module 500 further includes a driving mechanism. A transmission part is arranged at the end of the lead screw 210, and the driving mechanism can be used as a tool to drive the lead screw 210 to rotate through the transmission part. Specifically, a hexagonal transmission block can be welded and fixed at the end of the lead screw 210, or the end of the lead screw 210 can be machined into an external hexagonal shape to form a transmission part. The driving mechanism can be a hand drill 410. The external hexagonal transmission block corresponds to the sleeve of the hand drill 410. By rotating the lead screw 210 with the hand drill 410, the battery module 500 can be driven to move forward or backward. In other embodiments, the driving mechanism can also be a handle 420. The handle 420 corresponds to the external hexagonal fixing block at the end of the lead screw 210. In the case where the hand drill 410 has no power, the handle 420 is used for the disassembly and assembly operation of the battery module 500.

[0057] In one embodiment, as Figure 3As shown, the push rod assembly 300 includes a horizontal push rod 310 and two vertical push rods 320 which are respectively located at both ends of the horizontal push rod 310, and the vertical push rods 320 are used for fixedly connecting with the battery module 500. Specifically, one end of the vertical push rod 320 is detachably and fixedly connected to the end of the horizontal push rod 310, and a push rod pin is arranged at the other end, and the battery module 500 is fixedly connected to the vertical push rod 320 by using the push rod pin.

[0058] Further, in order to facilitate the complete installation of the battery module 500 in place, the vertical push rod 320 includes a short vertical push rod 321 and a long vertical push rod 322. Among them, in the initial installation stage, the short vertical push rod 321 is used, which can enable the support frame 100 to accommodate a battery module 500 with a longer size. When the horizontal push rod 310 moves to the limit position, if the battery module 500 has not completely disengaged from the support frame 100 at this time, the fixed connection relationship between the short vertical push rod 321 and the battery module 500 can be released first, and then the short vertical push rod 321 is disassembled, the horizontal push rod 310 is retracted to a position where the long vertical push rod 322 can be accommodated, the long vertical push rod 322 is replaced, and the long vertical push rod 322 is fixedly connected to the battery module 500, and the battery module 500 is continuously pushed until it moves in place.

[0059] In one embodiment, in order to reduce resistance, the push rod assembly 300 further includes two guiding sliders 331 which are fixed at both ends of the horizontal push rod 310, and two guide rails 332 extending along the axial direction of the lead screw 210 are arranged on the support frame 100, and the two guide rails 332 are in guiding sliding fit with the two guiding sliders 331 in a one-to-one correspondence.

[0060] In one embodiment, as Figure 5 shown, in order to limit the movement stroke of the horizontal push rod 310, the support frame 100 is provided with a first limit stop 111 and a second limit stop 112 for limiting the push rod assembly 300, and the first limit stop 111 and the second limit stop 112 are respectively located at both ends of the support frame 100. Specifically, in order to protect the horizontal push rod 310 and avoid damaging the horizontal push rod 310, buffer gaskets are arranged on both the first limit block and the second limit block, and the buffer gaskets can be made of rubber material or other materials with a buffering effect.

[0061] In one embodiment, as Figure 4 、 Figure 5 、 Figure 10 and Figure 11As shown, the support frame 100 includes a bottom frame 120 and an upper frame 110. The lead screw 210, the lead screw nut 220, and the push rod assembly 300 are arranged on the upper frame 110. There are three height adjustment mechanisms arranged in a triangle between the bottom frame 120 and the upper frame 110. The three height adjustment mechanisms are used to adjust the height and tilt angle of the upper frame 110, so as to adapt to uneven ground and solve the problem that the plane where the support frame 100 is located is not on the same horizontal plane as the installation plane during the disassembly and assembly of the battery module 500 due to uneven ground.

[0062] Specifically, the three height adjustment mechanisms are respectively a first adjustment mechanism 131, a second adjustment mechanism 132, and a third adjustment mechanism 133. The first adjustment mechanism 131 and the second adjustment mechanism 132 are arranged in parallel at intervals and are located at one end of the bottom frame 120. The third adjustment mechanism 133 is located at the other end of the bottom frame 120. For example, the third adjustment mechanism 133 can be located near the first limit stop 111. Preferably, a worm and worm gear reduction lift is used as the height adjustment mechanism, and the adjustable range reaches 100 mm. Among them, in order to flexibly adjust the plane where the support frame 100 is located, the output ends of the three height adjustment mechanisms are all hinged to the bottom frame 120. Among them, a spherical bearing 134 can be used for hinging between the output ends of the first adjustment mechanism 131 and the second adjustment mechanism 132 and the bottom frame 120, and a floating joint 135 can be used for hinging between the output end of the third adjustment mechanism 133 and the bottom frame 120 to expand the angle adjustment range.

[0063] In one embodiment, as Figure 4 shown, one end of the upper frame 110 is provided with an overhanging section, and the width of the overhanging section is smaller than the width of the rest part, so as to facilitate extending the overhanging section into the container to cooperate with the battery bracket 117 in the container, thereby facilitating the transfer of the battery module 500 into the container.

[0064] In one embodiment, a plurality of rollers 113 are arranged at intervals along the axial direction of the lead screw 210 on the upper frame 110. There are two rows of the rollers 113, which are respectively located on both sides of the lead screw 210 to reduce the resistance during the movement of the battery module.

[0065] In addition, in order to facilitate the hoisting of the upper frame 110, lifting rings 114 are arranged on both sides of the upper frame 110.

[0066] In one embodiment, as Figure 4 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown, protective fences 115 for laterally limiting the battery module 500 are provided on both sides of the upper layer frame 110, and blocking blocks 116 for longitudinally limiting the battery module 500 are also provided on both sides of the upper layer frame 110. Among them, the blocking block 116 includes a bracket 117, a fixing bolt 119, and a blocking pin 118. A long slot for the fixing bolt 119 to pass through is provided on the blocking pin 118, and a sliding slot for guiding the sliding of the blocking pin 118 is provided on the bracket 117. The blocking pin 118 extends longitudinally, and the blocking pin 118 can be fixed at a set position in the sliding slot through the fixing bolt 119, so that the blocking pin 118 has two states of extending and retracting. In the retracted state, the blocking pin 118 does not block the battery module 500 longitudinally. In the extended state, the blocking pin 118 can block corresponding structures on the battery module 500, such as lugs and other structures, so as to block the battery module 500 longitudinally.

[0067] In one embodiment, as Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown, in order to move the tooling stably and reliably, fork tooth grooves 121 for the fork teeth 600 of the forklift to be inserted are provided on the bottom frame 120, and a limiting component for limiting the fork teeth 600 is provided on the fork tooth grooves 121. Specifically, there are two fork tooth grooves 121. The limiting component includes a first limiting bolt 122 and a second limiting bolt 123 rotatably provided on the fork tooth grooves 121. The first limiting bolt 122 extends in the vertical direction and is used to limit the bottom surface of the fork teeth 600. The second limiting bolt 123 extends in the horizontal direction and is used to limit the side surface of the fork teeth 600. By adjusting the positions of the first limiting bolt 122 and the second limiting bolt 123, the bottom surface and the side surface of the fork teeth 600 can be limited to prevent relative sliding between the tooling and the fork teeth 600 during the moving process. Since the side area of the fork teeth 600 is small, in order to accurately limit the side surface of the fork teeth 600, preferably, a limiting block 124 is provided at the end of the second limiting bolt 123, and the limiting block 124 is used to limit the side surface of the fork teeth 600.

[0068] Furthermore, since first threaded blocks 125 and second threaded blocks 126 corresponding to the first limiting bolt 122 are fixedly provided on the fork tooth grooves 121, threaded holes for threadedly cooperating with the first limiting bolt 122 are provided in the first threaded block 125, and threaded holes for threadedly cooperating with the second limiting bolt 123 are provided in the second threaded block 126, so as to facilitate screwing the first limiting thread and the second limiting bolt 123, and thus it is only necessary to process through holes on the fork tooth grooves 121 instead of threaded holes.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
