[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0030] Example 1

[0031] like Figure 1 As shown, a power battery flip device comprises a bracket 1, a main board 2, and a pressure plate 3, the main board 2 is rotatably connected to the bracket 1, a flip driving member 4 for driving the main board 2 to rotate is provided on the bracket 1, and a battery pack is arranged between the main board 2 and the pressure plate 3;

[0032] A limit locking member 5 is provided on the main board 2, and the limit locking member 5 is used to lock the pressure plate 3 and limit the battery pack. A plurality of mounting holes 21 are provided on the main board 2, and the limit locking member 5 is detachably connected to the mounting holes 21.

[0033] By arranging the battery pack between the main board 2 and the pressure plate 3, and limiting the battery pack and locking the pressure plate 3 by means of a limit locking block, the battery pack can be flipped by rotating the main board 2; the limit locking member 5 is detachably connected to the mounting hole 21, and for different types of battery packs, adaptation can be achieved by simply moving the limit locking member 5 to a suitable mounting hole 21, and adjustment is convenient and flexible.

[0034] Example 2

[0035] like Figure 1 As shown, the difference between this embodiment and embodiment 1 is that: the limiting locking member 5 includes a guide positioning pin 51 and a quick-change clamp 53; the guide positioning pin 51 is detachably connected to the main board 2 through the mounting hole 21, and the pressure plate 3 is provided with a positioning hole 32 opposite to the guide positioning pin 51, and the guide positioning pins 51 are arranged on both sides of the two opposite sides (in this embodiment, the long sides) of the battery pack along the first direction; so that during the lowering of the pressure plate 3, the guide positioning pins 51 can guide the movement of the pressure plate 3, and after the pressure plate 3 is prevented from being in place, the guide positioning pins 51 can limit the pressure plate 3; during the flipping process, the guide positioning pins 51 on both sides of the battery pack can prevent the battery pack from sliding out. The surfaces of the main board 2 and the guide positioning pins 51 are sprayed with an insulating wear-resistant coating to improve durability.

[0036] The main board 2 is detachably connected to the limit support 52 through the mounting hole 21, and the quick-change clamp 53 is arranged on the limit support 52. The quick-change clamp 53 is used to lock the pressure plate 3. The limit supports 52 are arranged on both sides of the two opposite sides (the short sides in this embodiment) of the battery pack along the second direction, and the first direction is perpendicular to the second direction. The quick-change clamp 53 is rotatably connected to the limit support 52, and the quick-change clamp 53 is threadedly connected to the side of the pressure plate 3 away from the battery pack through the first bolt. During the falling process of the pressure plate 3, the quick-change clamp 53 is moved to one side. After the falling is completed, the quick-change clamp 53 is rotated to the top of the pressure plate 3, and the quick-change clamp 53 is threadedly connected to the pressure plate 3 through the first bolt, so that the pressure plate 3 can be locked.

[0037] The guide positioning pin 51 is provided with a threaded section, and the guide positioning pin 51 is threadedly connected to the screw hole through the threaded section, and the limit support 52 is threadedly connected to the mounting hole 21 on the main board 2 through the second bolt. The guide positioning pin 51 is installed to different mounting holes 21 through the threaded section, so that the spacing between the guide positioning pins 51 can be adjusted; the limit support 52 is installed to different mounting holes 21 by using the second bolt, so that the spacing between the limit supports 52 on both sides of the battery pack can be adjusted, thereby realizing the adjustment of the size of the space for accommodating the battery pack. The limit support 52 is retractable, so that it can adapt to battery packs of different heights.

[0038] The pressing plate 3 is provided with a lifting ring 31 , which is detachable to facilitate the lifting and movement of the pressing plate 3 .

[0039] The flip driving member 4 includes a power motor and a transmission gear connected to the power motor. The output end of the transmission gear is connected to the main board 2 through an output shaft 41. After the power motor is turned on, the output shaft 41 rotates through the transmission gear, which can drive the power to flip actively, thereby realizing the flipping of the battery pack. The bracket 1 is symmetrically arranged on both sides of the main board 2, and the flip driving member 4 is arranged on the brackets 1 on both sides to ensure the force balance of the main board 2; in order to avoid the impact on the ground during the working process, a base 11 is arranged under the bracket 1, and the contact area between the bracket 1 and the bottom surface is increased by the base 11.

[0040] It also includes a mobile lifting platform, which is used to receive and rotate the flipped battery pack.

[0041] Pressure plates 3 and limit locking members 5 are arranged on both sides of the main board 2, that is, the upper and lower sides of the main board 2 have the same structure. Therefore, when the battery pack on one side of the main board 2 is reversed, during the removal of the flipped battery pack below the main board 2, another battery pack to be flipped can be placed between the top of the main board 2 and the pressure plate 3, thereby greatly improving efficiency.

[0042] Implementation principle: place the battery pack on the main board 2, install the guide positioning pin 51 and the limit support 52 at the appropriate position according to the model and size of the battery pack, then hoist the lifting ring 31 on the pressure plate 3, and the pressure plate 3 is lowered to the top of the battery pack under the guidance of the guide positioning pin 51; rotate the quick-change clamp 53 and use the first bolt to lock the pressure plate 3. At this time, the pressure plate 3 and the battery pack are in a compressed state, and the lifting ring 31 is removed; then start the power motor to drive the main board 2 and the battery pack to flip 180 degrees. At this time, operate the mobile lifting platform to move it to the bottom of the pressure plate 3, and lift the mobile lifting platform to contact with the pressure plate 3. At this time, open the quick-change clamp 53 in turn, and then the mobile lifting platform drives the battery pack to descend. The battery pack can be moved to the designated area under the drive of the mobile lifting platform to start the flipping of the next battery pack.

[0043] Example 3

[0044] like Figure 2 As shown, the difference between this embodiment and embodiment 2 is that it also includes a box carrier 6, the box carrier 6 includes a plurality of positioning sliders 61 detachably connected to the mainboard 2, the plurality of positioning sliders 61 form a battery pack accommodating cavity, and a guide slope 611 is provided on the top of the positioning slider 61, so that when the battery pack is placed in the battery pack accommodating cavity, the guide slope 611 can play a guiding role.

[0045] A supporting crossbeam 62 is also provided on the main board 2. The supporting crossbeam 62 is arranged between the positioning sliders 61. The supporting crossbeam 62 is used to support the battery module in the battery pack box. Due to the high strength requirements of the power battery, the power battery pack box for engineering machinery is generally higher than the battery module. The battery module is supported by the supporting crossbeam 62, and then the box is turned upside down on top to ensure the stability of the flipping process.

[0046] Example 4

[0047] The difference between this embodiment and the third embodiment is that, in order to prevent the battery pack from being damaged by collision, the box carrier 6 further includes a bottom plate 63, and the positioning slider 61 and the supporting crossbeam 62 are both arranged on the bottom plate 63, so that the battery pack can be arranged on the box carrier 6 in advance, and the battery pack can be transferred by moving the box carrier 6 to the main board 2. The bottom plate 63 can be provided with fixing holes to facilitate the fixing between the bottom plate 63 and the battery pack or the bottom plate 63 and the main board 2.

[0048] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0049] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
