Description

Fixing assembly, support structure and energy storage device Technical Field The application relates to the technical field of energy storage, in particular to a fixing assembly, a bracket structure and an energy storage device. Background Currently, battery packs in energy storage devices are typically assembled to the cluster frame of the container using screws and fixing plates. Specifically, be provided with four through-holes on the fixed plate, the cluster frame left and right sides all corresponds respectively and is provided with four first mounting holes, and the left and right sides of battery package also corresponds respectively and is provided with four second mounting holes. When the battery pack is assembled, the battery pack is firstly loaded on the cluster frame, the second mounting hole on the battery pack is aligned with the first mounting hole on the cluster frame, then the fixing plate is held by hand to be attached to the outer side of the cluster frame, the through hole on the fixing plate is aligned with the first mounting hole on the cluster frame, and finally the battery pack is fixed on the cluster frame by using a screw to pass through the through hole on the fixing plate and the first mounting hole on the cluster frame and then be connected in the second mounting hole on the battery pack in a threaded manner. Because the left and right sides of battery package all need set up a fixed plate, then need eight screw in total just can be fixed in the cluster frame of container with a battery package, have not in advance spacing when installing the fixed plate moreover, need hold up the fixed plate and install, lead to the assembly process of battery package loaded down with trivial details, energy memory's packaging efficiency is low. Disclosure of utility model In view of the above, the present application provides a fixing assembly, a bracket structure and an energy storage device. In a first aspect, the present application provides a fixing assembly for fixing a to-be-fixed member in an energy storage device. The fixed subassembly includes mounting bracket, fixed plate and mounting. The mounting rack comprises a guide rail, the guide rail comprises a first surface and a second surface which are opposite to each other in the first direction, the first surface is used for bearing the to-be-fixed piece, and the guide rail is provided with a plug hole penetrating through the first surface and the second surface. The fixed plate comprises a plug-in portion and limiting portions which extend from two sides of the plug-in portion in the second direction towards the directions away from the plug-in portion in a protruding mode, the plug-in portion penetrates through the plug-in hole and is provided with a fixing hole, the fixing hole penetrates through the plug-in portion along the third direction, in the first direction, the fixing hole is located on one side of the first face, and the limiting portions are located on one side of the second face and are in butt joint with the second face. The first direction, the second direction and the third direction are perpendicular to each other. The fixing piece is used for penetrating through the fixing hole and the mounting hole on the to-be-fixed piece so as to fixedly connect the plug-in part with the to-be-fixed piece. In the technical scheme, after the to-be-fixed piece is borne on the first surface of the guide rail in the process of assembling the to-be-fixed piece on the container, the inserting hole of the guide rail can be penetrated by a single hand until the limiting part abuts against the second surface of the guide rail, at the moment, the fixing hole is aligned with the mounting hole on the to-be-fixed piece, the fixing piece is penetrated by the same hand and locked in the mounting hole on the to-be-fixed piece, so that the to-be-fixed piece can be mounted, on one hand, the interference design of the limiting part and the guide rail can realize the pre-limiting of the fixing plate, the fixing of the to-be-fixed piece is not needed to be additionally carried out by one hand, the single-person single-hand operation can be realized, thus, the assembly process of the to-be-fixed piece is greatly simplified, the assembly efficiency of the to-be-fixed piece on the container is facilitated, on the other hand, the fixing plate is only provided with one fixing hole, and the to-be-fixed piece is fixed on the container after the two fixing pieces respectively penetrate through the fixing holes on the fixing plates on the left side and the right side of the container, and the use quantity of the fixing piece is reduced from left to the right side to the two (the left side and the right side is greatly saved). As an optional technical scheme of the application, the plugging portion comprises a plugging sub portion and a reinforcing sub portion, the plugging sub portion is provided with a through hole and the fixing hole, the through hole penet
