[0033] In order to solve the problem that the initial position of the battery pack on the fixing frame is different from the actual position to be fixed in the related art, the battery pack needs to be re-adjusted to a suitable installation position and then the battery pack and the fixing frame are fixed. However, due to the heavy weight of the battery pack, it is inconvenient to adjust the position and the operation is difficult, which seriously affects the assembly efficiency.

[0034] 1 , a battery pack fixing structure is provided, which includes a base plate 100 and a fixing member 200 fixedly connected to the battery pack 500. In this embodiment, the fixing member 200 is preferably fixed to the side wall of the battery pack 500 by welding. The base plate 100 is used to carry the battery pack 500. The fixing member 200 can also be fixedly connected to the battery pack 500 by other means. The present application does not limit the fixed connection method. The battery pack 500 is fixed to the base plate 100 by the fixing member 200. A positioning member 300 is provided on the base plate 100. The positioning member 300 is used to guide the battery pack 500 to move to a preset installation position. A fixing member 200 is also provided on the fixing member 200. The moving member 400 is used to drive the battery pack 500 to move through the fixing member 200.

[0035] When installing the battery pack 500, the battery pack 500 is lifted and moved by connecting the movable member 400 to the fixed member 200, so that the battery pack 500 is moved to the accurate installation position under the guidance of the positioning member 300. The operation is easy, thereby improving the assembly efficiency of the base plate 100 and the battery pack 500.

[0036] 1 , the positioning member 300 includes a plurality of guide rods 310 arranged on the base plate 100 according to a preset installation position, the guide rods 310 are fixedly connected to the base plate 100, a plurality of guide grooves 320 matching the guide rods 310 are opened on the fixing member 200, the guide rods 310 are slidably connected in the guide grooves 320, the fixing member 200 is fixedly connected to the side wall of the battery pack 500, the guide grooves 320 extend toward the end face of the fixing member 200 away from the battery pack 500, and the guide grooves 320 are used for the rod body of the guide rod 310 to extend into.

[0037] When positioning the battery pack 500 , the guide rod 310 can be easily and quickly extended into the guide groove 320 , so that the guide rod 310 leans against the inner wall of the guide groove 320 , which is convenient for operation and saves assembly efficiency.

[0038] 1 , a connection hole 210 is formed on the fixing member 200 , and the connection hole 210 is used for detachably connecting the mobile battery pack 500 to the moving member 400 . The connection hole 210 is also used for connecting the battery pack 500 to the base plate 100 through the connection member 220 when fixing the battery pack 500 .

[0039] The moving part 400 is connected to the connection hole 210 to facilitate the moving part 400 to move the position of the battery pack 500; after the battery pack 500 is placed at a suitable position on the bottom plate 100, the moving part 400 is removed and connected to the bottom plate 100 through the connection hole 210 by the connection part 220. Through the above arrangement, one hole can be used for multiple purposes and space can be saved; and by removing the moving part 400, the weight of the battery pack 500 can be reduced, and the energy storage device can be lightweight.

[0040] It is worth mentioning that the fixing member 200 is arranged at the bottom of the side wall of the battery pack 500, and the end surface of the fixing member 200 facing the bottom plate 100 is aligned with the end surface of the fixing member 200 facing the bottom plate 100, so that the bottom surface of the fixing member 200 is in contact with the top surface of the bottom plate 100.

[0041] Through the above arrangement, the gap between the fixing member 200 and the bottom plate 100 is reduced, which helps to ensure the stability of the connection between the fixing member 200, the battery pack 500 and the bottom plate 100.

[0042] 1 , the moving member 400 includes a lifting ring 410. In some embodiments, in conjunction with FIG. 2 , an inner wall of the connecting hole 210 is provided with an internal thread matching the connecting end of the lifting ring 410, the connecting section of the lifting ring 410 is threadedly connected in the connecting hole 210, and a thread groove 230 matching the connecting member 220 is provided on the bottom plate 100, and the connecting member 220 is threadedly connected in the thread groove 230.

[0043] When the battery pack 500 needs to be moved, the lifting ring 410 is first threadedly connected to the connection hole 210, so that the lifting structure can move the battery pack 500 through the lifting ring 410; after the battery pack 500 is placed at a suitable position on the bottom plate 100, the lifting ring 410 is screwed down, and the connecting piece 220 passes through the connection hole 210 and is threadedly connected to the bottom plate 100. Through the above arrangement, one hole can be used for multiple purposes and space can be saved; and removing the moving piece 400 can reduce the counterweight of the battery pack 500 and lighten the energy storage device.

[0044] In this embodiment, referring to FIG. 1 , the fixing member 200 includes a tube 240 , one end of the tube 240 is disposed on the side wall of the battery pack 500 , and the guide groove 320 is disposed at one end of the tube 240 away from the battery pack 500 .

[0045] By configuring the fixing member 200 as a tube 240 , the fixing member 200 is configured to be hollow, which helps to reduce the weight of the battery pack 500 , thereby making the battery pack 500 lightweight.

[0046] 1 , the connecting hole 210 includes a first through hole 211 and a second through hole 212. The first through hole 211 is provided on the end face of the tube 240 away from the base plate 100. The connecting end of the lifting ring 410 passes through the first through hole 211 and is fixed on the end face of the tube 240 away from the base plate 100 by a movable nut. The second through hole 212 is provided on the end face of the tube 240 facing the base plate 100. The second through hole 212 is arranged corresponding to the thread groove 230. The connecting member 220 passes through the first through hole 211 and the second through hole 212 in sequence and is threadedly connected in the connecting hole 210 of the base plate 100.

[0047] In the process of moving the battery pack 500, the lifting ring 410 is first threadedly connected to the connecting hole 210, and then the corresponding movable nut is threadedly connected to the connecting end of the lifting ring 410 that passes through the first through hole 211, so that the lifting ring 410 is not easily offset relative to the first through hole 211 under the action of external force; after the battery pack 500 is moved to the preset installation position, the movable nut is removed, and then the lifting ring 410 is taken out from the first through hole 211, and the connecting piece 220 is sequentially passed through the first through hole 211 and the second through hole 212, and is threadedly connected to the thread groove 230 on the base plate 100, thereby ensuring that the bottom surface of the battery pack 500 and the top surface of the tube 240 are in contact with each other, and ensuring the connection strength among the battery pack 500, the fixing piece 200 and the base plate 100.

[0048] 1 , a side of the tube 240 away from the battery pack 500 is provided with an inclined surface 250 , the end surface where the second through hole 212 is located is longer than the end surface where the first through hole 211 is located, and the guide groove 320 is provided on the end surface where the second through hole 212 is located.

[0049] Through the above-mentioned setting, the guiding cooperation between the guide groove 320 and the guide rod 310 can be achieved. The inclined setting of the end of the tube 240 helps to observe whether the guide rod 310 extends into the guide groove 320 on the bottom surface of the tube 240, which is convenient for positioning the battery pack 500.

[0050] In other embodiments, in combination with FIG. 1 and Figure 3The top and bottom surfaces of the tube 240 are provided with guide grooves 320 at one end away from the battery pack 500. Providing guide grooves 320 on the top and bottom surfaces of the tube 240 helps to accurately position the battery pack 500 and avoid skewness.

[0051] 1 , at least two fixing members 200 are provided and are distributed in a ring shape on the side wall of the battery pack 500 , and a plurality of fixing members 200 are distributed on two opposite surfaces of the battery pack 500 .

[0052] By providing a plurality of fixing members 200, multi-point positioning of the battery pack 500 is achieved, which helps to prevent the battery pack 500 from rotating itself, thereby ensuring the accuracy of the positioning of the battery pack 500; by providing fixing members 200 on two opposite surfaces of the battery pack 500, both ends of the battery pack 500 are fixed, which helps to ensure the connection effect between the battery pack 500 and the base plate 100.

[0053] In other embodiments, referring to FIG. 4 , the fixing member 200 may be a fixing block, and the guide groove 320 is provided on a side of the fixing block away from the battery pack, and the inner surface of the guide groove 320 is engaged with the outer surface of the guide rod 310, and the surface of the guide rod 310 can be engaged with the inner surface of the guide groove 320, which helps to avoid the battery pack 500 being installed with the guide rod 310 as the axis, thereby helping to ensure the accuracy of the positioning of the battery pack 500.

[0054] Specifically, the working principle of the embodiment of the present application is as follows: during the installation of the battery pack 500, the connecting end of the lifting ring 410 is first passed through the first through hole 211 on the tube 240, and then the movable nut is tightened on the connecting end of the lifting ring 410, so that the lifting ring 410 is threadedly connected to the tube 240, and then the lifting equipment is started to drive the battery pack 500 to move until the guide groove 320 and the guide rod 310 on the tube 240 are pressed against each other, and under the guidance of the guide groove 320 and the guide rod 310, the battery pack 500 is gradually placed on the base plate 100, and then the lifting ring 410 is removed from the tube 240, and the connecting piece 220 is sequentially passed through the first through hole 211 and the second through hole 212, and is threadedly connected in the thread groove 230, so that the battery pack 500 is fixedly connected to the base plate 100.

[0055] The present application welds the fixing member 200 on the battery pack 500, and sets a lifting ring 410 on the fixing member 200, and adjusts the position of the battery pack 500 by lifting, so that the guide rod 310 on the bottom plate 100 extends into the guide groove 320 of the fixing member 200, thereby achieving accurate positioning of the battery pack 500, avoiding the need to adjust the position of the battery pack 500 after placing the battery pack 500 on the bottom plate 100; and the lifting method facilitates the horizontal movement of the battery pack 500, is simple to operate, and helps to ensure the assembly efficiency of the energy storage device;

[0056] The present application also provides a connection hole 210, which can be fixedly connected to the lifting ring 410 and can also be connected to the connecting piece 220 connecting the base plate 100, so as to achieve multiple uses of one hole, save space, and reduce the weight of the energy storage device.
