Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and in particular to a universal battery pack flipping and positioning device. Background Technology

[0002] With the widespread adoption and development of new energy vehicles, the battery packs in these vehicles sometimes require adjustments to their spatial orientation during inspection or maintenance. Traditionally, this is done by lifting the battery pack with a hoist and then manually manipulating it to change its position. However, due to the significant weight of the battery pack, especially in large electric vehicles, this method of using a hoist with manual assistance is not only cumbersome and time-consuming but also poses certain safety hazards.

[0003] In addition, in the above-mentioned operation method, after adjusting the battery pack to a suitable position, it is necessary to use an auxiliary mechanism to fix it in order to maintain the current position. When it is necessary to adjust the position of the battery pack again, the auxiliary mechanism needs to be used, which will greatly reduce the efficiency of battery pack maintenance.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content

The flipping frame 5 has two symmetrically distributed adjustable crossbeams 11 connected within it, and clamps 12 are provided on the outer side of each adjustable crossbeam 11. A coordinate system is set with the length and width directions of the flip frame 5, with the length direction as the X-axis and the width direction as the Y-axis, and the adjustable crossbeam 11 can move along the Y-axis direction.

[0022] Both ends of the adjustable crossbeam 11 are provided with nut blocks 13, which are threadedly connected to the double-helical screws 14. The double-helical screws 14 are rotatably supported on the flip frame 5, and the double-helical screws 14 are distributed along the Y-axis. The adjustable crossbeam 11 is further provided with a connecting plate 15 at its end. An upper slider 16 and a lower slider 17 are fixedly mounted on the connecting plate 15. The flipping frame 5 is provided with an upper slide rail 18 that is slidably connected to the upper slider 16 and a lower slide rail 19 that is slidably connected to the lower slider 17. The upper slide rail 18 and the lower slide rail 19 are distributed along the Y-axis direction. The two adjustable crossbeams 11 are respectively connected to two threaded sections with different directions of rotation on the same double-rotation screw 14 via nut blocks 13. The end of the double-rotation screw 14 is also provided with a second handwheel 20 located outside the flip frame 5.

[0023] The bottom of both the first support frame 1 and the second support frame 2 is provided with rollers 21 and adjustable feet 22.

[0024] The positioning pin support 9 is threaded with a set screw 23, and the end of the set screw 23 can contact the side wall of the positioning pin 10.

[0025] The clamp 12 includes a clamp bracket 24, an upper clamping plate 25 is movably connected to the clamp bracket 24, and a lower clamping plate 26 is provided below the upper clamping plate 25. The upper clamping plate 25 is rotatably connected to a drive bolt 27 threaded to the top plate of the clamp bracket 24. An elongated hole 28 is provided at the bottom of the clamp bracket 24, and the clamp bracket 24 is fixedly connected to the outside of the adjustable crossbeam 11 by a fixing bolt connected in the elongated hole 28.

[0026] The working process of the general-purpose battery pack flipping and positioning device of this utility model embodiment is as follows: First, the battery pack that needs to be inspected or maintained is moved to the device using a lifting tool. Then, the distance between the two adjustable crossbeams 11 is adjusted so that the clamps 12 set on them move to the position that contacts the edge of the battery pack. Then, the battery pack is fixed between the two adjustable crossbeams 11 using multiple clamps 12. Then, the flipping frame 5 is unlocked, and the first handwheel 4 drives the flipping frame 5 and the battery pack on it to flip in space. After flipping to the required angle, the positioning mechanism locks the positioning plate 7. At this time, the battery pack is in the required posture, and maintenance or inspection operations can be performed on it. The operator cranks the first handwheel 4, and the output end of the gearbox 3 drives the flipping frame 5 to rotate, thereby changing the flipping angle of the battery pack in space. When the desired angle is reached, the positioning pin 10 is pushed so that its end is inserted into the corresponding positioning hole 8 on the positioning plate 7. Then the set screw 23 is tightened to press the positioning pin 10. At this time, the positioning pin 10 is restricted in its axial degree of freedom, thereby realizing the locking operation of the positioning plate 7. The positioning pins 10 and positioning plates 7 at both ends of the flipping frame 5 are operated according to the above process. When it is necessary to change the distance between the two adjustable crossbeams 11, two workers need to hold the two second handwheels 20 simultaneously, rotating them in the same direction and at the same speed. The second handwheels 20 drive the double-rotating screw 14 to rotate, so that the adjustable crossbeams 11 connected to the double-rotating screw 14 via the nut block 13 will move along the Y-axis. Since the ends of the two adjustable crossbeams 11 are respectively connected to the threaded sections of the two ends of the same double-rotating screw 14 with different directions of rotation, the two adjustable crossbeams 11 move in opposite directions (moving towards each other or back to back), thereby changing the distance between the two adjustable crossbeams 11 to accommodate different battery pack specifications. When it is necessary to use the clamp 12 to clamp the battery pack, rotate the drive bolt 27 to drive the upper clamp 25 downward. The upper clamp 25 and the lower clamp 26 are used to clamp the edge of the battery pack, thereby fixing the battery pack to the flip frame 5. At the same time, since the bottom of the clamp bracket 24 has an elongated hole 28, the specific installation position of a clamp 12 on the adjustable beam 11 can be determined as needed to adapt to battery packs of different specifications.
