Description

Technical Field

[0001] This utility model relates to the field of battery casing technology, and in particular to a shock-resistant battery casing for forklifts. Background Technology

[0002] Forklift operating conditions: Frequent starts and stops, bumpy roads, and cargo impacts cause the battery pack to be subjected to continuous vibration (5-50Hz) and instantaneous impacts.

[0003] To improve the stability of battery pack operation, a shock-resistant battery casing is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a shock-resistant battery casing for forklifts. By setting a first damping block and a second damping block between the inner casing and the outer casing, along with an elastic element and a rubber diaphragm, a buffering effect is achieved, thereby reducing the vibration of the battery pack.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shock-resistant battery housing for forklifts, comprising a battery pack and an inner housing for housing the battery pack, an outer housing and a top cover disposed outside the inner housing, wherein a buffer mechanism is provided between the inner housing and the outer housing, the buffer mechanism comprising a first damping block disposed at the bottom of the inner housing and a second damping block disposed at the bottom of the outer housing and cooperating with the first damping block, wherein elastic elements are provided at both ends of the first damping block, a connecting plate is fixedly connected to the end of the elastic element away from the first damping block, and the other side of the connecting plate away from the elastic element is fixedly connected to the inner wall of the outer housing.

[0006] By adopting the above technical solution, the battery pack is installed inside the inner casing. A first damping block is provided at the bottom of the inner casing, and a second damping block is provided at the bottom inner side of the outer casing to cooperate with the first damping block. The first damping block and the second damping block are slidably connected. Elastic elements are provided at both ends of the first damping block. The elastic elements are springs or other components with elastic force. The elastic elements play a buffering role, and together with the rubber diaphragms provided on both sides of the inner casing, they play a shock absorption role for the battery pack.

[0007] The present invention is further configured such that: rubber septa are provided on both sides of the inner shell, and the other end of the rubber septa abuts against the inner wall of the outer shell.

[0008] By adopting the above technical solution, when the outer shell is impacted, the rubber septum installed between the inner shell and the outer shell provides a buffering effect for the battery pack inside the inner septum.

[0009] The present invention is further configured such that: a limiting frame is provided at the bottom of the top cover, and the bottom of the limiting frame abuts against the top of the rubber partition.

[0010] By adopting the above technical solution, the limiting frame at the bottom of the top cover abuts against the top of the rubber partition. The contact between the limiting frame and the rubber partition increases the friction between the limiting frame and the rubber partition, thereby achieving the effect of maintaining stability.

[0011] The present invention is further configured such that the top cover is bolted to the outer shell.

[0012] By adopting the above technical solution, users can easily remove and install the top cover to facilitate the replacement and maintenance of the outer shell, inner shell, and battery pack housed in the inner shell.

[0013] The present invention is further configured such that at least one set of vent holes is provided around the perimeter of the inner shell.

[0014] By adopting the above technical solution, one or more sets of vent holes can be set according to actual production needs for heat dissipation of the inner shell.

[0015] The present invention is further configured such that the outer casing has at least one heat dissipation vent.

[0016] By adopting the above technical solution, the outer casing dissipates heat through the heat dissipation vents.

[0017] In summary, this utility model has the following beneficial effects:

[0018] By setting a first damping block and a second damping block between the inner shell and the outer shell, along with elastic elements and rubber diaphragms, a buffering effect is achieved, thereby reducing the vibration of the battery pack. Attached Figure Description
