[0038] Example 1

[0039] A power battery turning operation table, such as Figure 1As shown, it comprises a frame 1, the frame 1 is provided with a slide rail 2, the slide rail 2 is provided with at least two sliding blocks 3 in the extension direction, and a turnover mechanism 4 for overturning the power battery module and a lifting mechanism 5 for lifting the power battery module are sequentially arranged along the extension direction of the slide rail 2. Each slide rail 2 is provided with two guide rods arranged in parallel, and each sliding block 3 is provided with four embedding blocks for nesting on the guide rods, two of which are arranged on one guide rod, and the other two are arranged on the other guide rod, ensuring the smooth movement of the sliding block 3. Its role is that through the arrangement of the sliding block 3, the turnover mechanism 4 and the lifting mechanism 5, the power battery module can be placed on the sliding block in the area where the turnover mechanism 4 is located first, and then the power battery module is overturned by 90 degrees through the turnover mechanism 4, that is, the power battery module bottom plate can be removed, and then the power battery module is overturned by 90 degrees in the opposite direction through the turnover mechanism 4 to return to the sliding block above the area where the turnover mechanism 4 was located before the first overturning, and the power battery module is moved along the extension direction of the slide rail 2 to the above of the lifting mechanism 5 through the sliding block, and then the power battery module is lifted by the lifting mechanism 5, and each sliding block 3 is moved to the corresponding power battery box in the power battery module one by one. After that, lower the lifting mechanism 5, so that each power battery box in the power battery module falls on the corresponding sliding block 3, and then separate the battery box connecting piece connecting each power battery box on the power battery module, and then use the sliding block 3 to separate the different power battery boxes along the slide rail 2 by a certain interval, so as to repair and replace the single power battery in each power battery box.

[0040] Specifically, as shown in the figure, Figure 2 The slide rail 2 is provided with two and the two slide rails 2 are arranged in parallel with each other, and the turnover mechanism 4 and the lifting mechanism 5 are arranged between the two slide rails 2. Its role is that through the design of the space layout between the slide rail 2 and the turnover mechanism 4 and the lifting mechanism 5, the movement of the sliding block 3 can be avoided by the turnover mechanism 4 and the lifting mechanism 5.

[0041] Specifically, as shown in the figure, Figure 1As shown, the flipping mechanism 4 includes a flipping frame 6, which is hinged to the frame 1 via a rotating shaft 7. The rotating shaft 7 extends perpendicularly to the direction of extension of the slide rail 2. The flipping frame 6 includes a fixed rod 8 and a telescopic rod 9 that extends and retracts along its length, with the fixed rod 8 and the telescopic rod 9 positioned perpendicularly to the rotating shaft 7. The flipping frame 6 is provided with a through hole for receiving the telescopic rod 9. When horizontally positioned, the fixed rod 8 and the telescopic rod 9 are both lower than the top of the slide 3. The flipping mechanism 4 functions as follows: the arrangement of the rotating shaft 7 enables the flipping frame 6 to rotate about the rotating shaft 7, thereby flipping the power battery module. The arrangement of the fixed rod 8 and the telescopic rod 9 supports two adjacent sides of the power battery module. Before flipping, the fixed rod 8 is positioned at the bottom of the power battery module, while the telescopic rod 9 is positioned at the side of the power battery module. After flipping, the telescopic rod 9 is positioned at the bottom of the power battery module, while the fixed rod 8 is positioned at the side of the power battery module.

[0042] Specifically, such as Figure 1 As shown, a pressure plate 10 is provided on the top of the telescopic rod 9 and is arranged parallel to the fixed rod 8. Its function is to press the top surface of the power battery module before flipping through the setting of the pressure plate 10, thereby supporting the telescopic rod 9 and preventing the telescopic rod 9 from falling.

[0043] Specifically, such as Figure 5 As shown, the tilting mechanism 4 further includes a tilting hydraulic cylinder 11, which is articulated to the frame 1 via a first hinge shaft 12. The tilting hydraulic cylinder 11 is articulated to the tilting frame 6 via a second hinge shaft 13. Both the first hinge shaft 12 and the second hinge shaft 13 are arranged parallel to the rotating shaft 7. The function of the mechanism is to fix the position of the tilting frame 6 by the arrangement of the tilting hydraulic rod, and when the tilting hydraulic rod is driven to extend or retract, the tilting frame 6 is driven to tilt.

[0044] Specifically, such as Figure 1 As shown, the lifting mechanism 5 includes a support plate 14 arranged parallel to the top surface of the frame 1. Connected below the support plate 14 is a lifting hydraulic cylinder 15 arranged perpendicular to the support plate 14 in its extension and retraction direction. The lifting mechanism 5 supports the power battery module through the support plate 14 and raises and lowers the power battery module on the support plate 14 through the lifting hydraulic rod.

[0045] Specifically, such as Figure 8 As shown, a guide shaft 16 is provided between the support plate 14 and the lifting hydraulic cylinder 15. A guide sleeve 17 is provided on the guide shaft 16 perpendicular to the support plate 14. The guide sleeve 17 is fixedly connected to the frame 1. The guide shaft 16 and the guide sleeve 17 are arranged to fix the moving direction of the support plate 14.

[0046] Specifically, such as Figure 8 As shown, a connecting plate 18 is fixedly connected between the guide sleeve 17 and the frame 1. Its function is to fix the guide sleeve 17 through the setting of the connecting plate 18.

[0047] Specifically, such as Figure 8 As shown, a bearing 19 is provided on one end of the guide shaft 16 adjacent to the lifting hydraulic cylinder 15. The bearing 19 is connected to the lifting hydraulic cylinder 15. The bearing 19 is a tapered roller bearing 19. The bearing 19 enables the support plate 14 to rotate through any angle of 360 degrees.

[0048] Specifically, such as Figure 1 As shown, the frame 1 is provided with a battery rack 20 for storing power batteries that need to be replaced.

[0049] The working principle of this embodiment is described as follows: Figure 3 As shown, when the power battery module needs to be flipped, the flip hydraulic cylinder 11 is driven to make the fixed rod 8 parallel to the top surface of the frame 1, and the telescopic rod 9 is pulled up. First, one set of sliders 3 is moved to the fixed rod 8, and the other set of sliders 3 is moved to the area where the telescopic rod 9 is flipped. The power battery module is placed on the sliders 3 located at the fixed rod 8, and the sliders 3 are moved to make the power battery module close to the pulled telescopic rod 9. The telescopic rod 9 is lowered to make the pressure plate 10 press on the top surface of the power battery module. Then, the flip hydraulic cylinder 11 is driven to extend, so that the flip hydraulic cylinder 11 pushes the flip frame 6 to rotate around the rotating shaft 7, so that the fixed rod 8 is turned from a horizontal state to a vertical state, and the telescopic rod 9 is turned from a vertical state to a horizontal state, as shown in FIG. Figure 4 As shown, the flipped power battery module finally falls on the slider 3 located on the area where the telescopic rod 9 is flipped, completing the first flip of the power battery module. At this time, the load-bearing bottom plate under the power battery module can be removed.

[0050] like Figure 4 As shown, after the bottom plate under the power battery module is removed, the flip hydraulic cylinder 11 is driven to shorten, so that the flip hydraulic cylinder 11 pulls the flip frame 6 to rotate in the opposite direction around the rotation axis 7, so that the fixed rod 8 is turned from the vertical state to the horizontal state, and the telescopic rod 9 is turned from the horizontal state to the vertical state. The power battery module falls again on the slider 3 located in the area where the fixed rod 8 was before the first flip, and then the telescopic rod 9 is retracted. Figure 6 shown.

[0051] When the power battery module needs to be disassembled, such as Figure 7 As shown, Figure 6 The power battery module and the slider 3 in the slide rail 2 move to the top of the support plate 14, as shown in FIG. Figure 8As shown, the lifting hydraulic cylinder 15 is driven to make the support plate 14 vertically hold up the power battery module, and then each slider 3 is moved so that a slider 3 is provided directly below each power battery box in the power battery module, as shown in FIG. Figure 9 As shown, the lifting hydraulic cylinder 15 is driven to lower the power battery module, and the battery box connectors connecting the power battery boxes on the power battery module are removed, so that each power battery box can be moved individually and the single power batteries inside the power battery box can be repaired and replaced.

[0052] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
