Description

Technical Field

[0001] The utility model relates to the field of positioning of energy storage batteries, and more specifically, to a battery pack installation structure. Background Art

[0002] In order to balance the temporal and geographical fluctuations of wind power generation and photovoltaic power generation, the prior art provides a method of using energy storage batteries to reduce the peak load and fill the valley to suppress the fluctuation of power generation.

[0003] In order to accommodate the huge amount of electricity measured in MW, batteries are generally managed in a modular and hierarchical manner in the form of a cell-battery pack-battery cluster.

[0004] In the process of assembling the existing battery pack to form a battery cluster, it is necessary to load the battery pack into the frame body. In the related art, the battery pack is loaded by a forklift. Due to the heavy weight of the battery pack, the friction between the battery pack and the frame body causes it to get stuck easily during loading and unloading, making disassembly difficult.

[0005] In summary, the present application aims to provide a battery pack installation structure that can optimize the battery pack and the frame body, thereby reducing the probability of getting stuck. Summary of the invention

[0006] The utility model overcomes the disadvantage that the existing battery cluster is easy to get stuck during the loading and unloading process, and provides a battery pack installation structure, which can optimize the battery pack and the frame body, thereby reducing the probability of getting stuck.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A battery pack mounting structure comprises a frame body for accommodating the battery pack and the battery pack, the frame body being provided with a plurality of mounting rails arranged at equal intervals along the height direction, the mounting rails being arranged on the left and right sides of the frame body, the mounting rails being provided with lower grooves arranged along the length direction of the mounting rails, the lower grooves being provided with a plurality of balls arranged on them, adjacent balls being fitted together, and the tops of the balls being higher than the surfaces of the mounting rails.

[0009] The frame body supports accommodating several battery packs. There is a controlled gap between adjacent battery packs, rather than stacking them directly. Controlling the distance between the battery packs is achieved by installing rails. The mounting rails are fixedly connected to the frame body by welding and clamping. The mounting rails are arranged on both sides of the battery pack, and the battery pack shell itself resists the bending moment caused by the weight of the battery pack, so that the weight of the mounting rails will not be very high, reducing the overall quality. The side walls of the mounting rails restrict the battery pack from sliding out from the side wall direction. By providing a lower groove on the surface of the mounting rail and providing a ball in the lower groove, the friction of the battery pack insertion is reduced, the resistance is reduced, and the probability of being stuck is reduced.

[0010] Preferably, the mounting rail further includes a side positioning flange, which is used to fit the side fitting edge of the lower part of the battery pack. The distance between the side positioning flanges of the mounting rails at the left and right ends is set to adapt to the width of the lower part of the battery pack, so as to achieve the purpose of clamping the main battery pack in the left and right directions, so that the battery pack will not shake left and right due to the activity gap in the left and right directions during transportation, thereby preventing a collision accident.

[0011] Preferably, the battery pack includes a lower portion of the battery pack protruding outward, and a jump-limiting flange is provided on the top of the mounting rail, and the jump-limiting flange is attached to the top surface of the lower portion of the battery pack. The jump-limiting flange is attached to the top of the lower portion of the battery pack from the top direction, thereby limiting the battery pack from jumping upward.

[0012] Preferably, the jump-up limiting flange is upwardly warped at one end in the length direction to form a guide warp, which plays a guiding role and better guides the battery pack into the installation rail during installation.

[0013] Preferably, the width of the notch of the lower groove is smaller than the diameter of the ball, so as to prevent the ball from escaping from the notch of the lower groove.

[0014] Preferably, the lower groove of the mounting rail is a through groove with both ends open, the mounting rail abuts against the rear end of the frame body of the frame body, the front end of the frame body is fixedly connected with a limiting plate, the limiting plate is fixedly connected to the battery pack and the frame body by fasteners, and the limiting plate closes the front end of the mounting rail. In addition to limiting the battery pack from being pulled out of the frame body, the limiting plate is also used to close the lower groove to prevent the ball from rolling out.

[0015] As a preference, a reinforcing beam is also included, the reinforcing beam is L-shaped, the reinforcing beam is attached to the lower part of the frame body, and the reinforcing beam is fixedly connected to the frame body. The mounting beam strengthens the strength of the mounting rail.

[0016] Preferably, the reinforcing beam is provided with reinforcing ribs.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) the ball bearing reduces the friction between the mounting rail and the battery pack, thereby preventing the battery pack from getting stuck during the pull-out installation process; (2) the lower groove, the side positioning flange and the jump limit flange fit the lower part of the battery pack, thereby limiting the movement of the battery pack in the left and right and up and down directions, preventing the battery pack from moving relative to the mounting rail, and reducing metal fatigue and the resulting failure caused by relative movement.

[0028] The frame body supports accommodating a number of battery packs 1. There is a controlled gap between adjacent battery packs 1, rather than being directly stacked. Controlling the distance between the battery packs 1 is achieved by installing the guide rails 3. The mounting rails 3 are fixedly connected to the frame body by welding and clamping. The mounting rails 3 are arranged on both sides of the battery pack 1, and the shell of the battery pack 1 itself resists the bending moment caused by the weight of the battery pack 1, so that the weight of the mounting rails 3 will not be very high, reducing the overall quality. The side walls of the mounting rails 3 limit the battery pack 1 from sliding out from the side wall direction. By providing a lower groove 4 on the surface of the mounting rail 3 and providing a ball 5 in the lower groove 4, the friction of the insertion of the battery pack 1 is reduced, the resistance is reduced, and the probability of being stuck is reduced.

[0029] The mounting rail 3 also includes a side positioning flange, which is used to fit the side fitting edge 6 of the lower part of the battery pack 1. The bottom of the battery pack 1 is provided with a battery positioning structure 2 extending outward in the horizontal direction. The side positioning flange distances of the mounting rails 3 at the left and right ends are set to adapt to the width of the lower part of the battery pack 1, so as to achieve the purpose of clamping the left and right directions of the main battery pack 1, so that the battery pack 1 will not shake left and right due to the activity gap in the left and right directions during transportation, thereby causing a collision accident. The battery pack 1 includes a lower part of the battery pack 1 protruding outward, and a jump-up limiting flange 7 is provided on the top of the mounting rail 3, and the jump-up limiting flange 7 is fitted with the top surface of the lower part of the battery pack 1. The jump-up limiting flange 7 is fitted on the top of the lower part of the battery pack 1 from the top direction, thereby limiting the battery pack 1 from jumping up. The jump-up limiting flange 7 is upwardly tilted at one end in the length direction to form a guide tilt 8, which plays a guiding role and better guides the battery pack 1 into the mounting rail 3 during installation. The mounting rail 3 is a sheet metal part, which is specifically formed by bending once to form a side positioning flange, folded again to form a jump-up limiting flange 7, and then folded again at the front of the jump-up limiting flange 7 to form a guide warped edge 8.

[0030] The lower groove 4 of the mounting rail 3 is a through groove with both ends open. The mounting rail 3 abuts against the rear end of the frame body of the frame body. The front end of the frame body is fixedly connected with a limit plate 9. The limit plate 9 is fixedly connected to the battery pack 1 and the frame body by fasteners, and the limit plate 9 closes the front end of the mounting rail 3. In addition to limiting the battery pack 1 from being pulled out of the frame body, the limit plate 9 is also used to close the lower groove 4 to prevent the ball 5 from rolling out. A reinforcing beam 10 is also included. The reinforcing beam 10 is L-shaped. The reinforcing beam 10 is attached to the bottom of the frame body and is fixedly connected to the frame body.
