It has a simple structure and reduces the use of parts.

[0036] 2. The first bolt of the vertical double-layer battery frame assembly of the present invention is a long bolt head bolt, and a through hole is provided at a corresponding position on the upper base plate to ensure that the first bolt can be screwed through the through hole of the upper base plate. The first battery below can be removed without removing the second battery installed on the upper base plate and the upper base plate.

[0037] 3. The vertical double-layer battery frame assembly of the present invention uses spring retaining rings at both ends as bearing clamps. When the long bolt head bolt is installed, the convex part of the bolt head is pressed to the lower side of the spring retaining ring. When the long bolt is removed, the convex part of the bolt head cannot pass through the spring retaining ring upward due to the restriction of the spring retaining ring, so that the lower pressure plate moves with the bolt head, so that a gap appears between the lower pressure plate and the first battery, and the first battery can be taken out, making disassembly more convenient.

[0038] 4. The vertical double-layer battery frame assembly of the present invention is provided with mounting holes at different positions on the lower base plate, upper base plate and side plates along the second direction.

[0039] 5. The battery disassembly and assembly method of the present invention is that when the second battery above is disassembled alone, the second bolt is screwed until the second bolt is separated from the upper base plate, and the upper pressure plate and the second bolt are taken out upward, and the second battery can be taken out from the upper end; when the first battery is disassembled alone, the first bolt is screwed, and the lower pressure plate moves upward following the first bolt. During the movement, the first bolt is never separated from the lower base plate. After the lower pressure plate moves upward, a gap appears between the lower pressure plate and the first battery. After the fourth limit plate is removed, the first battery can be taken out along the second direction. The first battery can be directly disassembled and assembled without the need for an artificial lifting structure, which is convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Example 1:

[0052] See also Figure 1 As shown, an embodiment of the present application provides a vertical double-layer battery frame assembly, comprising: a lower base plate 1; an upper base plate 2, the upper base plate 2 and the lower base plate 1 are arranged parallel to each other with an upper and lower spacing; a side plate 6, the side plate 6 is connected to both sides of the lower base plate 1 and the upper base plate 2 along the first direction, and the side plate 6 includes a first side plate 61 and a second side plate 62; the lower base plate 1, the upper base plate 2 and the side plate 6 enclose a first chamber and a second chamber, and the lower base plate 1, the upper base plate 2 and the side plate 6 are all provided with mounting holes at different positions along the second direction; a limit plate 5, the limit plate 5 is provided at both ends of the lower base plate 1 and the upper base plate 2 along the second direction, and is connected in the mounting hole; the first direction and the second direction are perpendicular. In this embodiment, the first direction can be regarded as the X-axis direction in the three-dimensional coordinate system, and the second direction can be regarded as the Y-axis direction in the three-dimensional coordinate system.

[0053] The first chamber enclosed by the lower base plate 1, upper base plate 2, and side plates 6 is used to house a first battery 100. The second chamber enclosed by the upper base plate 2 and side plates 6 is used to house a second battery 200. The two batteries are placed vertically side by side, creating a compact layout. Limiting plates 5 are located at both ends of the lower base plate 1 and upper base plate 2 along the second direction and are connected to the mounting holes. By changing the position of the limiting plates, different battery sizes can be retained.

[0054] See also Figure 1 、 Figure 2 As shown, the vertical double-layer battery frame assembly also includes two lower pressure plates 3, which are clamped between the side plates 6 and connected to the lower base plate 1 at upper and lower intervals through a first bolt; both ends of the two lower pressure plates 3 along the first direction are provided with a connecting hole 1, and each connecting hole 1 is provided with a bearing clamp 31; the first end of the first bolt is installed in the bearing clamp 31, and the second end is screwed into the threaded hole set in the corresponding position of the lower base plate 1 at the connecting hole 1, the first lower pressure plate 3 is screwed to the lower base plate 1 through the first bolt a85 and the first bolt b86, and the second lower pressure plate 3 is screwed to the lower base plate 1 through the first bolt c87 and the first bolt d88; the upper pressure plate 4, the upper pressure plate 4 is clamped between the two side plates 6 and connected to the upper base plate 2 at upper and lower intervals through the second bolt; the upper pressure plate 4 is provided with a connecting hole 2 at both ends along the first direction, the first end of the second bolt is installed in the connecting hole 2, and the second end is screwed into the threaded hole set in the corresponding position of the connecting hole 2 on the upper base plate 2. The upper pressing plate 4 is screwed to the upper base plate 2 by a second bolt a81 , a second bolt b82 , a second bolt c83 and a second bolt d84 .

[0055] By providing a second bolt between the upper pressing plate 4 and the upper base plate 1 and a first bolt between the lower pressing plate 4 and the lower base plate 2, the vertical movement of the battery can be restricted, and the battery can be kept stably installed.

[0056] The upper base plate 2 has four through-holes corresponding to the first connection holes. First bolts a85, b86, c87, and d88 pass through these through-holes to connect the lower pressure plate 3 to the lower base plate 1. Corresponding through-holes are provided on the upper base plate 2, located at the edge of the upper base plate 2. These through-holes remain exposed even after the second upper battery 200 is installed. This ensures that the first bolts can be removed from the through-holes in the upper base plate 2, allowing the first battery below to be removed without removing the second battery installed on the upper base plate or the upper base plate.

[0057] The limiting plate 5 includes a first limiting plate 51, a second limiting plate 52, a third limiting plate 53 and a fourth limiting plate 54;

[0058] The first limiting plate 51 and the second limiting plate 52 are both arranged in the second chamber. The first limiting plate 51 is arranged at one end of the upper base plate 2 along the second direction and connected to the mounting hole of the upper base plate 2. The second limiting plate 52 is arranged at the other end of the upper base plate 2 along the second direction and connected to the mounting hole of the upper base plate 2.

[0059] The third limiting plate 53 and the fourth limiting plate 54 are both arranged in the first chamber. The third limiting plate 53 is arranged at one end of the lower base plate 1 along the second direction and is connected to the mounting hole of the lower base plate 1. The fourth limiting plate 54 is arranged at the other end of the lower base plate 1 along the second direction and is connected to the mounting hole of the side panel 6.

[0060] The four limiting plates can limit the two batteries in the second direction, and can adjust the installation position according to the size of the batteries, thereby adapting to batteries of different sizes.

[0061] See also Figure 3 As shown, the vertical double-layer battery frame assembly also includes a cover plate 7, which includes a horizontal plate and a vertical plate that are perpendicular to each other. The first end of the horizontal plate is connected to the first end of the vertical plate, the second end of the horizontal plate is detachably connected to the side plate 6, and the second end of the vertical plate is detachably connected to the lower base plate 1. After the cover plate 7 is installed, the lower base plate 1, the side plates 4, and the cover plate form a cubic space.

[0062] See also Figure 1 As shown, the side panels 61 and 62 are provided with reinforcing ribs and weight-reducing holes, which reduce weight while improving the structural strength of the side panels 61 and 62 .

[0063] See also Figure 5As shown, the first bolt is a long bolt head bolt with a longer bolt head and a through hole is opened at the corresponding position on the upper base plate to ensure that the first bolt can be screwed through the through hole of the upper base plate. The first battery below can be removed without removing the second battery installed on the upper base plate and the upper base plate.

[0064] See also Figure 4 As shown, further, the bearing clamp 31 is a spring collar.

[0065] The lower pressure plate 3 uses spring retaining rings as bearing clamps at both ends along the first direction. When the long bolt head bolt is installed, the convex part of the bolt head is pressed to the lower side of the spring retaining ring. When the long bolt is removed, the convex part of the bolt head cannot pass through the spring retaining ring upward due to the restriction of the spring retaining ring, so that the lower pressure plate moves with the bolt head, and a gap appears between the lower pressure plate and the first battery, so that the first battery can be taken out, and disassembly is more convenient.

[0066] Example 2:

[0067] The embodiment of the present application provides a method for disassembling and assembling a battery for the above-mentioned vertical double-layer battery frame assembly, including a battery installation method and a battery removal method. In this embodiment, the first direction can be regarded as the X-axis direction in the three-coordinate system, and the second direction can be regarded as the Y-axis direction in the three-coordinate system.

[0068] How to install the battery:

[0069] Frame assembly: Place the lower base plate 1 horizontally. Install the third limiting plate 53 at the first end of the lower base plate 1 along the second direction, based on the size of the first and second batteries 100 and 200 to be installed. Place the upper base plate 2 horizontally, install the first limiting plate 51 at the first end of the upper base plate 2 along the second direction, and install the second limiting plate 52 at the second end of the upper base plate 2 along the second direction. Securely connect the lower base plate 1 and the upper base plate 2 to the side plates 6. This completes the assembly of the basic frame.

[0070] Install the first battery 100: Place two lower pressing plates 3 on the upper end surface of the first battery 100, push the first battery 100 into the first chamber along the second direction until the first end of the first battery 100 abuts the third limiting plate 53, install the fourth limiting plate 54 on the second end of the lower base plate 1 along the second direction, so that the fourth limiting plate 54 abuts the second end of the first battery 100; install the first bolt to connect the lower pressing plate 3 and the lower base plate 1, and fix the first battery 100 in the first chamber;

[0071] Install the second battery 200: Place the second battery 200 between the first limiting plate 51 and the second limiting plate 52 in the second chamber, with both ends of the second battery 200 abutting against the first limiting plate 51 and the second limiting plate 52, respectively. Place two upper pressing plates 4 on the upper end surface of the second battery 200, and install second bolts to connect the upper pressing plates 4 and the upper base plate 2 to secure the second battery 200 in the second chamber.

[0072] Install the cover 7.

[0073] To remove the battery:

[0074] When removing the second battery 200 separately, tighten the second bolt until the second bolt is separated from the upper base plate 2, first remove the upper pressure plate 4 and the second bolt upward, and then remove the second battery 200 from the upper end;

[0075] When removing the first battery 100 alone, tighten the first bolt from the through hole of the upper base plate 2, and the lower pressure plate 3 moves upward following the first bolt. However, the first bolt is never separated from the lower base plate 1 during the movement of the first bolt. After the lower pressure plate 3 moves upward, a gap appears between it and the first battery 100. After removing the fourth limit plate 54, the first battery 100 is taken out along the second direction.

[0076] This method allows for direct disassembly and assembly of the battery without the need for manual lifting of the structure, thus facilitating maintenance.
