Preferably, the longitudinal section of the support plate 12 is L-shaped.

[0039] In some embodiments, the number of guide grooves 121a and fixing holes 121b can be multiple. In the present embodiment, the number of guide grooves 121a on each horizontal plate 121 is two, the number of fixing holes 121b on each horizontal plate 121 is one, and one of the guide grooves 121a is adjacent to the fixing hole 121b, that is, one of the guide grooves 121a and the fixing hole 121b are both arranged at the same end of the horizontal plate 121.

[0040] The positioning assembly 13 is used to locate the installation position of the battery pack on the horizontal plate 121, and is also connected between the columns 113 on the frame body 11. The positioning assembly 13 includes a positioning plate 131, a fixed plate 132, a telescopic rod 133 and a connecting plate 134, wherein the fixed plate 132 is installed between the columns 113, the telescopic rod 133 is hinged to the fixed plate 132 and is transmission-connected to the positioning plate 131 through the connecting plate 134, and the connecting plate 134 is hinged between the fixed plate 132 and the positioning plate 131, and the positioning plate 131 is installed at the bottom of the horizontal plate 121 of the support plate 12 and is adapted to the guide groove 121a. It should be noted that, in order to facilitate the determination of the installation status of the battery pack 2 in the battery rack 1, when the battery pack 2 is pushed into the battery rack 1 in a direction parallel to the length direction of the support plate 12 under the action of an external force, the top of the positioning plate 131 is flush with the notch of the guide groove 121a, and the telescopic rod 133 is in a retracted state; when the battery pack 2 is installed in a preset position in the battery rack 1, the top of the positioning plate 131 protrudes from the notch of the guide groove 121a, and the telescopic rod 133 is in an extended state, please refer to Figure 2 , Figure 3 .

[0041] In this embodiment, in order to make the telescopic rod 133 telescopically change under the drive of the power mechanism, and then drive the positioning plate 131 to move up and down, the fixed plate 132 is provided with a waist hole 132a, and the waist hole 132a is arc-shaped, so as to ensure that the movement trajectory of the end of the telescopic rod 133 hinged to the fixed plate 132 meets the requirements.

In this way, when the battery pack 2 is installed in place in the battery rack 1, the first limiter 123 is provided, which is beneficial to reduce the vibration amplitude of the battery pack 2 in the vertical direction.

[0043] Furthermore, if Figure 4 As shown, the vertical plate 122 also has a second limiting portion 124 for limiting the movement of the battery pack 2 in the left-right direction. The second limiting portion 124 is in the shape of a convex block, formed at the intersection of the horizontal plate 121 and the vertical plate 122, and is arranged on the same side of the vertical plate 122 as the first limiting portion 123. In this way, when the battery pack 2 is pushed into the battery rack 1 along a direction parallel to the length direction of the support plate 12 under the action of an external force, the second limiting portion 124 is helpful to limit the movement of the battery pack 2 in the left-right direction.

[0044] Furthermore, one end of the horizontal plate 121 has a third limiting portion 125 for limiting the movement of the battery pack 2 in the front-to-back direction. The third limiting portion 125 is plate-shaped and formed at the bottom end of the installation position of the battery pack 2, including an abutting portion for abutting the battery pack 2 and a transition portion connected between the abutting portion and the horizontal plate 121, wherein the transition portion is integrally formed with the edge of the horizontal plate 121, and the abutting portion extends toward the area where the installation position is located. Preferably, the longitudinal section of the third limiting portion 125 is L-shaped, that is, the angle between the transition portion and the abutting portion is a right angle. In this way, when the battery pack 2 is installed in place in the battery rack 1, the third limiting portion 125 is provided, which is beneficial to limiting the movement of the battery pack 2 in the front-to-back direction, thereby ensuring that the battery pack 2 will not be damaged during transportation.
