When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0040] Such as Figures 1 - 3As shown in the figure, a fixing device for fixing a battery pack mainly includes: a connecting member 1, a first fixing component 2, and a second fixing component 3. Among them, the first fixing component 2 and the second fixing component 3 are symmetrically arranged. The connecting member 1 is preferably a connecting plate 221, and a plurality of connecting plates 221 are provided along the length direction of the first fixing component 2 and the second fixing component 3 to ensure reliable connection between the first fixing component 2 and the second fixing component 3. During use, the fixing device is fixed to the trolley by fixing the plurality of connecting plates 221 to the trolley, facilitating the test.

[0041] One end of the connecting member 1 is connected to the first fixing component 2, and the connection position of the connecting member 1 on the first fixing component 2 can be adjusted left and right. The other end of the connecting member 1 is connected to the second fixing component 3, and the connection position of the connecting member 1 on the second fixing component 3 can be adjusted left and right. Since the connection positions at both ends of the connecting member 1 can be adjusted left and right on the first fixing component 2 and the second fixing component 3 respectively, the distance between the first fixing component 2 and the second fixing component 3 can be adjusted, and thus the fixing device in this embodiment can fix battery packs of different widths, with a wide range of applications.

[0042] Both the first fixing component 2 and the second fixing component 3 include a connecting bracket 21 and a fixing bracket 22. The battery pack can be fixed between the fixing brackets 22 of both; the fixing bracket 22 is arranged on the connecting bracket 21, and the height of the fixing bracket 22 on the connecting bracket 21 is adjustable, so that the height of the battery pack can be adjusted, facilitating the adjustment of the ground clearance of the battery pack during the battery pack scraping test.

[0043] Specifically, as Figures 1 - 5As shown in the figure, the specific implementation method for the adjustable height of the fixed bracket 22 on the connecting bracket 21 is as follows: The connecting bracket 21 is provided with a plurality of first gear slots 211, and the fixed bracket 22 is fixed in the first gear slots 211 through the first fixing bolts 23. The first fixing bolts 23 can be switched among the plurality of first gear slots 211 to adjust the height of the battery pack. Among them, the plurality of first gear slots 211 are arranged in parallel and at different heights, that is, the plurality of first gear slots 211 are arranged along the height direction on the connecting bracket 21; one ends of the plurality of first gear slots 211 are connected through the first communication slot 212, and the first fixing bolts 23 can be switched between the plurality of first gear slots 211 along the first communication slot 212, making it convenient to adjust the height of the fixed bracket 22, that is, convenient to adjust the height of the battery pack. Preferably, the fixing device of this embodiment further includes a first locking member 24. When the first fixing bolt 23 fixes the fixed bracket 22 in one of the first gear slots 211, the first locking member 24 can be locked into the first gear slot 211. Among them, one end of the first locking member 24 abuts against the first fixing bolt 23, and this end of the first locking member 24 has an arc surface that is in contact with the first fixing bolt 23. The other end of the first locking member 24 abuts against the side wall of the first communication slot 212 to lock the first fixing bolt 23 in the first gear slot 211. This end of the first locking member 24 is a flat surface that is in contact with the side wall of the first communication slot 212. By locking the first fixing bolt 23 in the first gear slot 211 through the first locking member 24, it is ensured that the first fixing bolt 23 will not shift, and the structural stability is good. Moreover, it is simple to disassemble and assemble the first locking member 24 from the first gear slot 211.

[0044] Among them, the cross-section of the fixed bracket 22 is arranged in an L shape, which includes a connecting plate 221 and a fixing plate 222. The fixing plate 222 is provided with a plurality of fixing holes 220 along its length direction, and the battery pack can be fixed in the fixing holes 220. The connecting plate 221 is connected to the connecting bracket 21, and the fixing plate 222 is connected to the battery pack. There are also through holes on the battery pack, and bolts can pass through the through holes and the fixing holes 220 to fix the battery pack on the fixing plate 222.

[0045] Specifically, the specific implementation method for the two ends of the connecting member 1 to have adjustable fixed positions on both the first fixing component 2 and the second fixing component 3 is as follows: The connecting bracket 21 is provided with a plurality of second gear slots 213 along its width direction (i.e., the left-right direction), and the end of the connecting member 1 is fixed in the second gear slot 213 through the second fixing bolt 25. The second fixing bolt 25 can be switched between a plurality of second gear slots 213 to adjust the distance between the first fixing component 2 and the second fixing component 3, so that the fixing device can fix battery packs of different widths. Among them, one end of the plurality of second gear slots 213 is connected through the second communication slot 214, and the second fixing bolt 25 can be switched between the plurality of second gear slots 213 along the second communication slot 214, ensuring that the adjustment of the distance between the first fixing component 2 and the second fixing component 3 is simple. Moreover, a row of second gear slots 213 is respectively provided on both sides of the connecting bracket 21 along the second communication slot 214, and one end of the two rows of second gear slots 213 is connected through the second communication slot 214. The two rows of gear slots on both sides of the second communication slot 214 are arranged staggeredly, ensuring as many gears as possible within a limited width range to be applicable to battery packs of different widths. Among them, the fixing device of this embodiment further includes a second locking member 26, and the structure of the second locking member 26 is similar to that of the first locking member 24, and the disassembly, installation, and use methods are the same. When the second fixing bolt 25 fixes the end of the connecting member 1 in one of the second gear slots 213, the second locking member 26 can be locked into the second gear slot 213. Among them, one end of the second locking member 26 abuts against the second fixing bolt 25, and the other end of the second locking member 26 abuts against the side wall of the second communication slot 214, locking the second fixing bolt 25 in the second gear slot 213 to ensure that the second fixing bolt 25 will not shift in the second gear slot 213, and the first fixing component 2 and the second fixing component 3 fix the battery pack reliably.

[0046] Preferably, as Figure 6 shown, the connecting bracket 21 of this embodiment includes an upper bracket 21A and a lower bracket 21B. The lower bracket 21B is rotatably connected to the upper bracket 21A so that the inclination angle of the battery pack fixed on the fixing bracket 22 can be adjusted, facilitating the adjustment of the inclination angle of the battery pack during the test, such as during the battery pack scraping test. Among them, the fixing bracket 22 is installed on the lower bracket 21B and moves along with the movement of the lower bracket 21B. Moreover, when the lower bracket 21B rotates and adjusts the angle relative to the upper bracket 21A, a spacer block 27 is placed between the upper bracket 21A and the lower bracket 21B to ensure that there is no relative movement between the upper bracket 21A and the lower bracket 21B and ensure the fixing stability of the battery pack.

[0047] During use, the fixed positions at both ends of the connecting member 1 in this embodiment can be adjusted left and right on the first fixing component 2 and the second fixing component 3 respectively, thereby adjusting the distance between the first fixing component 2 and the second fixing component 3, and the fixing of battery packs with different widths can be achieved. In the first fixing component 2 and the second fixing component 3, the fixing brackets 22 can be adjusted up and down relative to the connecting brackets 21, so that the height of the battery pack can be adjusted, which is convenient for conducting the battery pack scraping test. The connecting bracket 21 includes an upper bracket 21A and a lower bracket 21B that are hinged to each other. The lower bracket 21B rotates relative to the upper bracket 21A to adjust the inclination angle of the battery pack. The overall structure of the fixing device is simple, and it can be applied to battery packs of different specifications and sizes. Moreover, after the battery pack is fixed, the inclination angle and height of the battery pack are adjustable, and the adjustment is convenient.

[0048] In this solution, the fixing device can be used to fix battery packs of different models and sizes, and the height and inclination angle of the battery pack are adjustable. The overall structure of the fixing device is simple.
