[0038] Based on the plug-in assembly provided by the utility model, the first plug-in block 1 can be installed on one of the battery modules 4, the second plug-in block 2 can be installed on another battery module 4, the first plug-in block 1 and the second plug-in block 2 are plug-in matched, on this basis, the first plug-in block 1 and the second plug-in block 2 are further plug-in matched through the first guide piece 11 and the second guide piece 21, the plug-in assembly adopting the plug-in matching mode of twice guiding can increase the connection and positioning precision between the battery modules 4, increase the positioning efficiency and the reliability of guiding, and solve the problems of variability and low service life existing in the separate structure guiding, and the first plug-in block 1 and the second plug-in block 2 after plug-in can be connected through one fixing piece 3, the convenience of assembly is increased, and the assembly efficiency is ensured.

[0039] In some embodiments, one of the first plug-in block 1 and the second plug-in block 2 is provided with a slot 12, and the other is provided with a plug-in plate 22 matched with the slot 12, and the plug-in matching of the two is realized through the slot 12 and the plug-in plate 22.

[0040] As a feasible implementation manner, continuing to refer to Figures 1 to 4 , the first plug-in block 1 is provided with a slot 12, and the second plug-in block 2 is provided with a plug-in plate 22 matched with the slot 12. Among them, the slot 12 is opened on the side of the first plug-in block 1 facing the second plug-in block 2, and correspondingly, the plug-in plate 22 is arranged on the side of the second plug-in block 2 facing the first plug-in block 1, and the plug-in plate 22 can be inserted into the slot 12. The plug-in plate 22 is integrally formed with the second plug-in block 2, and the structural strength is increased. Specifically, the slot 12 is arranged in the length direction of the first plug-in block 1, that is, along the x direction in Figure 1 , the plug-in plate 22 is arranged in the length direction of the second plug-in block 2, that is, along the x direction in Figure 1 , the length of the slot 12 is less than the length of the first plug-in block 1, and the length of the plug-in plate 22 is less than the length of the slot 12, where the length refers to the size of the first plug-in block 1 and the second plug-in block 2 along the x-axis direction in Figure 1 .

[0041] It can be understood that, as another feasible implementation manner, the second plug-in block 2 is provided with a slot, and the first plug-in block 1 is provided with a plug-in plate matched with the slot. Among them, the slot is opened on the side of the second plug-in block 2 facing the first plug-in block 1, and correspondingly, the plug-in plate is arranged on the side of the first plug-in block 1 facing the second plug-in block 2, and the plug-in plate can be inserted into the slot.

[0042] It can be seen that the plug-in manner of the first plug-in block 1 and the second plug-in block 2 is not limited, and can be selected according to actual needs.

[0043] In this design, the first insert 1 and the second insert 2 move toward each other, allowing the insert plate 22 to be inserted into the slot 12, thus achieving the cooperation of the first insert 1 and the second insert 2, and providing a guiding and positioning effect for the connection of the first component and the second component.

[0044] In some implementations, such as Figure 3 As shown, the corresponding two sides of the first insert 1 protrude towards the second insert 2 to form support plates 15, and a slot 12 is formed between the two support plates 15. Specifically, the first insert 1 has support plates 15 on both sides along its length direction. Figure 1 On both sides of the x-axis, the support plate has a columnar structure. The outer side of the support plate 15 is flush with the outer side of the first insert 1, making the edge of the first insert 1 smooth. The thickness of the support plate 15 is the same as the thickness of the first insert 1, that is, the support plate 15 and the first insert 1 are aligned along the x-axis. Figure 1 The dimensions in the y-axis direction are consistent.

[0045] In this design, the slot 12 adopts an open structure, which makes it easy for the insert plate 22 to be inserted into the slot 12.

[0046] It is understandable that the slot 12 can also be set on the second plug block 2, and the plug plate 22 can be set on the first plug block 1. These are not restrictive and can be designed according to actual needs.

[0047] In some implementations, combined Figure 2 and Figure 3 As shown, the first insert 1 along its thickness direction ( Figure 1 A back plate 16 is provided on one side (in the y-axis direction) towards the direction of the second insert 2, and the back plate 16 and the two support plates 15 form a slot 12.

[0048] In this design, the connection area between the first insert block 1 and the first component can be increased by setting the back plate 16, thereby increasing the connection strength.

[0049] In some implementations, combined Figure 2 and Figure 4 As shown, the length of the insert plate 22 ( Figure 1 The dimension in the x-axis direction) and the length of the second insert 2 ( Figure 1 The dimensions along the x-axis are the same, and the thickness of the insert 22 is ( Figure 1 The dimension in the y-axis direction is smaller than the thickness of the second insert 2. Figure 1 (Dimensions in the y-axis direction). Specifically, one side of the insert plate 22 is flush with one side of the second insert block 2, so as to form a stepped surface between the other side of the insert plate 22 and the second insert block 2. After the insert plate 22 is inserted into the slot 12, the stepped surface can abut against the end of the back plate 16 to ensure the positioning effect.

[0050] In some embodiments, in combination with Figure 2 and Figure 3 As shown in the drawings, the first inclined surface 121 is arranged on the inner side of the branch plate 15 at the end facing the second block 2, where the inner side refers to the two sides opposite to the second block 2, and the inclination angle of the first inclined surface 121 is not limited and can be designed according to actual needs.

[0051] In this design, the first inclined surface 121 makes the end of the slot 12 flared, facilitating the insertion of the plug-in plate 22 into the slot 12.

[0052] In some embodiments, in combination with Figure 2 and Figure 4 As shown in the drawings, the second inclined surface 221 is arranged on the corresponding two side walls of the plug-in plate 22. Specifically, the second inclined surface 221 is arranged on the corresponding two sides of the plug-in plate 22 along the length direction, so that the length of the end of the plug-in plate 22 gradually decreases in the direction towards the first block 1.

[0053] In this design, the second inclined surface 221 makes the end of the plug-in plate 22 tapered, further facilitating the insertion of the plug-in plate 22 into the slot 12.

[0054] In some embodiments, one of the first guide 11 and the second guide 21 comprises a guide hole 111, and the other comprises a guide post 211, and the guide hole 111 and the guide post 211 are matched.

[0055] As a feasible embodiment, in combination with Figures 2 to 4 As shown in the drawings, the first guide 11 comprises a guide hole 111 arranged on the first block 1, and the second guide 21 comprises a guide post 211 arranged on the second block 2, and the guide hole 111 and the guide post 211 are matched.

[0056] It can be understood that as another feasible embodiment, the first guide 11 comprises a guide post arranged on the first block 1, and the second guide 21 comprises a guide hole arranged on the second block 2, and the guide hole and the guide post are matched.

[0057] It can be seen that the design of the first guide 11 and the second guide 21 is not limited and can be selected according to actual needs.

[0058] In this design, the insertion of the guide post 211 into the guide hole 111 has a guiding and positioning effect for the connection of the first component and the second component, increasing the convenience of stacking the first component and the second component.

[0059] In some embodiments, the guide hole 111 is arranged along Figure 1The z-axis direction is set in the first insert 1, wherein the bottom end of the guide hole 111 is open, and the guide hole 111 and the slot 12 are aligned along the z-axis direction. Figure 1 The positions of the guide pins 111 and 211 are relative in the z-axis direction. At this point, the open end of the guide hole 111 connects to the slot 12. The top of the guide hole 111 can be open or closed, depending on the actual requirements. The guide post 211 runs along... Figure 1 The z-axis direction is set on the second insert block 2. Specifically, the guide post 211 is set on the insert plate 22 of the second insert block 2. That is, the top of the insert plate 22 extends towards the first insert block 1 and is provided with the guide post 211. This allows the guide post 211 to be inserted into the guide hole 111 during the insertion of the insert plate 22 into the slot 12, increasing the convenience of guidance and making the structure of the first insert block 1 and the second insert block 2 more compact.

[0060] In some implementations, combined Figure 2 and Figure 4 As shown, the end of the guide post 211 is provided with a tapered guide surface.

[0061] In this design, the tapered guide surface causes the end of the guide post 211 to form a constricted structure, which makes it easier for the guide post 211 to be inserted into the guide hole 111.

The second insert 2 has a screw hole 23 that matches the fixing bolt 31 (the screw of the fixing bolt 31).

[0064] During installation, after the first plug 1 and the second plug 2 are plugged in, the through hole 13 and the screw hole 23 are positioned opposite each other. The screw of the fixing bolt 31 passes through the through hole 13 and is screwed into the screw hole 23 until the nut of the fixing bolt 31 abuts against the first plug 1, thereby achieving a fixed connection between the first plug 1 and the second plug 2.

[0065] As another feasible implementation, the fastener 3 includes a fixing bolt, the fixing bolt 31 includes a screw and a nut, the second insert 2 is provided with a through hole through which the fixing bolt 31 (the screw of the fixing bolt 31) can pass, and the first insert 1 is provided with a screw hole 23 that matches the fixing bolt 31 (the screw of the fixing bolt 31).

[0066] It can be seen that the design of the fixing member 3 is not limited and can be selected according to actual needs. It can be understood that the number of the fixing member 3 can also be two or more according to actual needs to ensure the connection strength.

[0067] The connection mode is convenient to disassemble and assemble, firm in connection, and the connection effect can be ensured by one fixing bolt 31, thereby increasing the disassembly and assembly efficiency.

The relative position here refers to the vertical orientation of the second clearance groove 14 and the lifting hole 24. It can be understood that, as another feasible implementation, a second clearance groove is provided at the position corresponding to the lifting hole 24 of the second insert 2.

The "corresponding" refers to the lifting hole 24, the first clearance groove 25, and the second clearance groove 14 along... Figure 1 The positions along the z-axis are relative.

[0079] In this design, the hook of the hoisting equipment passes through the hoisting hole 24 and extends into the first clearance groove 25. At this time, the bent position of the hook or the knot position is opposite to the position of the second clearance groove 14, so that the second clearance groove 14 can provide clearance for the bent position of the hook or the knot position, avoiding the phenomenon of the first insert 1 scraping against the bent position of the hook or the knot, ensuring the use effect of the first insert 1 and the second insert 2. At the same time, it avoids the phenomenon of the bent position of the hook or the knot scraping against the first insert 1, causing wear to the first insert 1, thus ensuring the service life of the first insert 1.
