Top open type light-weight power battery cover assembly of low-entrance city bus

Abstract

The invention discloses a top open type light-weight power battery cover assembly of a low-entrance city bus. The assembly comprises a shell, an aluminum alloy rectangular pipe framework, two access doors and a drainage device; the shell is composed of an aluminum plate made of aluminum alloy; The two sides of the shell are bent and fixed to a passenger car roof modeling part through screws; and the two access doors are arranged on the two sides above the middle of the shell respectively. The assembly has the beneficial effects that the access doors on the top the cover are made of a light honeycomb aluminum plate material and are lighter than a common aluminum alloy cabin door; the size of the access doors can be reasonably designed in combination with the space for battery maintenance and even disassembly; the access doors are installed on the cover shell through hinges and locked through rotary locks; when maintenance is needed, maintenance can be conducted only by unlocking the locks and turning over the access doors, so that the access doors are very convenient to use; and according to the aluminum alloy drainage device, a sealing rubber strip is arranged on the edge of the notch of the drainage device, and when the access doors are closed, the access doors tightly press the sealing rubber strip to prevent water from entering the cover.

Description

technical field [0001] The invention relates to a power battery cover assembly, in particular to a lightweight power battery cover assembly with an open top for a low-entrance city bus, and belongs to the technical field of power battery cover assembly applications. Background technique [0002] At present, low-entrance city buses are popular in first- and second-tier cities, but due to the limited battery installation space of low-entry city buses, most of the batteries are installed on the top of the vehicle, and the two sides of the top are designed to be covered with enclosures, which is difficult for ordinary Battery cover installation adds to the difficulty. [0003] Ordinary battery covers are generally made of glass fiber material and made into a sealed structure. The disadvantages are difficult maintenance, large size, heavy weight, insufficient strength, easy collapse, and high development costs. At present, the development level of power batteries has been greatl...

Problems solved by technology

[0003] Ordinary battery covers are generally made of glass fiber material and made into a sealed structure. The disadvantages are difficult maintenance, large size, heavy weight, insufficient strength, easy collapse, and high development costs

At present, the development level of power batteries has been greatly improved. The waterproof level of the new generation of liquid-cooled batteries has reached IP68. Ordinary rainwater is generally not affected, but the heat dissipation requirements are higher.
