It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0039] On the one hand, if Figures 1 to 3 As shown, a plug box and battery cluster frame fixing structure of the utility model includes an assembly part 1, a boss part 2 and a connecting part 3;

[0040] The assembly part 1 and the boss part 2 are respectively arranged at one end of the plug box 4 and on the battery cluster frame 5, and the assembly part 1 is provided with an assembly hole 11, and the inner contour size and shape of the assembly hole 11 are adapted to the outer contour size and shape of the boss part 2;

[0041] When the plug box 4 is inserted into the battery cluster frame 5 , the boss member 2 is inserted into the assembly hole 11 , and the connector 3 connects the other end of the plug box 4 to the battery cluster frame 5 .

[0042] Specifically, the plug-in box and battery cluster frame fixing structure can fix both opposite ends of the plug-in box 4 on the battery cluster frame 5, and limit the plug-in box 4 in all directions in the X-axis, Y-axis and Z-axis directions.

[0043] The assembly part 1 and the boss part 2 can be respectively arranged at one end of the plug-in box 4 and the battery cluster frame 5. In this embodiment, the assembly part 1 is arranged on one end surface of the plug-in box 4 inserted in the battery cluster frame 5, the boss part 2 is arranged inside the battery cluster frame 5, and the assembly part 1 and the boss part 2 are arranged relatively to each other. The assembly part 1 can be provided with an assembly hole 11, and the inner contour size and shape of the assembly hole 11 can be adapted to the outer contour size and shape of the boss part 2, so that the boss part 2 can be inserted into the assembly hole 11, and when the boss part 2 is inserted into the assembly hole 11, the boss part 2 and the assembly hole 11 are in an interference fit state.

[0044] When the plug box 4 is inserted into the battery cluster frame 5, the boss member 2 can be inserted into the assembly hole 11. Since the boss member 2 and the assembly hole 11 are in an interference fit state, the assembly member 1 and the boss member 2 can limit the plug box 4 in the directions of the Y axis and the Z axis, and the connecting member 3 can connect the other end of the plug box 4 to the battery cluster frame 5, so that the connecting member 3, the assembly member 1 and the boss member 2 can limit the plug box 4 in the direction of the X axis.

[0045] Therefore, the two opposite ends of the plug box 4 can be fully limited and fixed in the X-axis, Y-axis and Z-axis directions through the connecting member 3, the assembly member 1 and the boss member 2, so that the plug box 4 is firmly fixed on the battery cluster frame 5.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the assembly hole 11 is a truncated cone hole, the boss part 2 is a truncated cone part, and the inner diameter of the assembly hole 11 gradually increases along its axis toward the boss part 2, and the outer diameter of the boss part 2 gradually decreases along its axis toward the assembly part 1.

[0047] Preferably, the assembly hole 11 is a truncated cone hole, the boss member 2 is a truncated cone member, and the inner diameter of the assembly hole 11 gradually increases along its axis toward the boss member 2, and the outer diameter of the boss member 2 gradually decreases along its axis toward the assembly member 1, so that when the boss member 2 and the assembly hole 11 just come into contact, the smaller end of the boss member 2 first comes into contact with the larger end of the assembly hole 11, and within a certain deviation range, the two can be inserted into each other without interference at all, and in the process of gradually pushing the plug box 4 into the battery cluster frame 5, the moving trajectory of the plug box 4 can also be guided, so that the plug box 4 can be installed more accurately.

[0048] like Figure 8 As shown, in some embodiments, the plug box and battery cluster rack fixing structure further includes a buffer member 6 , and the buffer member 6 is coated on the side wall of the boss member 2 , or the buffer member 6 is arranged on the inner wall of the assembly hole 11 .

[0049] Specifically, the fixing structure of the plug box and the battery cluster rack may further include a buffer member 6. Preferably, the buffer member 6 is a foam layer. In this embodiment, the buffer member 6 may be coated on the outer wall of the boss member 2, or the buffer member 6 may be arranged on the inner wall of the assembly hole 11. In other embodiments, the buffer member 6 may be arranged on the outer wall of the boss member 2 and the inner wall of the assembly hole 11.

[0050] When the boss member 2 is inserted into the assembly hole 11, the buffer member 6 can be located between the boss member 2 and the assembly hole 11. On the one hand, it can alleviate the collision between the boss member 2 and the assembly member 1. On the other hand, since the buffer member 6 has a certain elasticity, it can also fine-tune the error generated when the plug-in box 4 is assembled on the battery cluster frame 5.

[0051] like Figure 2 and Figure 8As shown, in some embodiments, the plug-in box and the battery cluster rack fixing structure also includes a U-shaped bracket 7, the closed end of the U-shaped bracket 7 is arranged on the battery cluster rack 5, and the U-shaped bracket 7 is located between the two plug-in boxes 4. When the two plug-in boxes 4 are inserted into the battery cluster rack 5, the two plug-in boxes 4 are in contact with the U-shaped bracket 7 respectively.

[0052] Specifically, the plug-in box and battery cluster rack fixing structure may further include a U-shaped bracket 7 , the closed end of the U-shaped bracket 7 may be arranged on the battery cluster rack 5 , and the open end of the U-shaped bracket 7 is arranged upward, and the U-shaped bracket 7 may be located between the two plug-in boxes 4 .

[0053] When the two plug-in boxes 4 are both inserted into the battery cluster frame 5, the two plug-in boxes 4 can respectively contact the opposite side plates of the U-shaped bracket 7, or it can be said that the two plug-in boxes 4 squeeze the opposite side plates of the U-shaped bracket 7. Since the open end of the U-shaped bracket 7 is not closed, the U-shaped bracket 7 has a certain elasticity. After the two plug-in boxes 4 are respectively fixed to the battery cluster frame 5 by multiple connecting members 3, the U-shaped bracket 7 is clamped between the two plug-in boxes 4, which can make the two plug-in boxes 4 installed more firmly.

[0054] like Figure 2 and Figure 8 As shown, in some embodiments, the boss member 2 or the assembly member 1 is respectively provided on the two opposite side plates of the U-shaped bracket 7 .

[0055] Specifically, a boss part 2 or an assembly part 1 can be respectively provided on the two opposite side plates of the U-shaped bracket 7. In the present embodiment, a boss part 2 is respectively provided on the two opposite side plates of the U-shaped bracket 7, and an assembly part 1 is respectively provided on the plug-in boxes 4 on the opposite sides of the U-shaped bracket 7. When the two plug-in boxes 4 are both inserted into the battery cluster rack 5, the assembly parts 1 on the two plug-in boxes 4 and the two boss parts 2 on the U-shaped bracket 7 are assembled together one by one, so that the two plug-in boxes 4 can be installed more firmly.

[0056] like Figure 2 and Figure 4 As shown, in some embodiments, the plug box and battery cluster frame fixing structure also includes a guide bracket 8, which is arranged on the battery cluster frame 5, and the guide bracket 8 is located on the side of the U-shaped bracket 7. The guide bracket 8 is used to contact the plug box 4 and guide the assembly part 1 on the plug box 4 and the boss part 2 to be aligned.

[0057] Specifically, in order to ensure that the plug-in box 4 can smoothly enter the battery cluster frame 5 , the channel on the battery cluster frame 5 for the plug-in box 4 to slide is generally slightly larger than the width of the plug-in box 4 , so that there will be a slight deviation when the plug-in box 4 is inserted into the battery cluster frame 5 .

[0058] In this embodiment, the fixing structure of the plug box and the battery cluster frame may further include a guide bracket 8, which may be arranged on the battery cluster frame 5, and the guide bracket 8 may be located on the side of the U-shaped bracket 7. In the process of gradually pushing the plug box 4 into the battery cluster frame 5, one end of the plug box 4 may first contact the guide bracket 8, and the guide bracket 8 may guide the assembly part 1 and the boss part 2 on the plug box 4 to be aligned, or it may be said that it guides the assembly hole 11 and the boss part 2 to be aligned, so that the boss part 2 can be inserted into the assembly hole 11, and there will be no interference between the boss part 2 and the assembly hole 11, so that the boss part 2 and the assembly hole 11 can be better assembled together.

[0059] like Figure 2 As shown, in some embodiments, the guide bracket 8 includes an L-shaped plate 81 and a straight plate 82, one end of the L-shaped plate 81 is connected to the battery cluster frame 5, one end of the straight plate 82 is connected to the other end of the L-shaped plate 81, and the straight plate 82 and the L-shaped plate 81 are inclined, and the other end of the straight plate 82 is connected to the battery cluster frame 5.

[0060] Specifically, the guide bracket 8 may include an L-shaped plate 81 and a straight plate 82. In this embodiment, the L-shaped plate 81 includes a long plate and a short plate, the long plate and the short plate are vertically connected to each other, one end of the short plate is connected to a plate on the battery cluster frame 5, and for the convenience of description, the plate is defined as a mounting plate, so that there is a certain distance between the long plate and the mounting plate on the battery cluster frame 5, and the long plate and the mounting plate are arranged in parallel, one end of the straight plate 82 can be connected to the long plate, and the straight plate 82 and the long plate are arranged obliquely, and the other end of the straight plate 82 can be connected to the mounting plate on the battery cluster frame 5, so that the straight plate 82 is arranged obliquely relative to the mounting plate.

[0061] When the latch is inserted into the battery cluster frame 5, one end of the plug-in box 4 may first contact the straight plate 82, and the plug-in box 4 gradually moves along the straight plate 82 until it contacts the L-shaped plate 81. In this process, the deviation generated when the plug-in box 4 is inserted into the battery cluster frame 5 can be corrected, so that the assembly part 1 on the plug-in box 4 and the boss part 2 on the battery cluster frame 5 are aligned.
