Description

TECHNICAL FIELD

[0001] The utility model relates to battery protection technical field, concretely is a new energy heavy truck battery skin group. BACKGROUND

[0002] Most new energy electric vehicles install power batteries behind the cab, and the periphery of the battery needs to be protected, mainly dustproof, rainproof, fireproof, electric shock prevention, and collision prevention. The battery is fixed on a metal frame, and the skin covers the top and the periphery of the frame. It is the main device for isolating the battery from the outside world. Different sizes of battery capacity require different sizes and installation structures of the peripheral skin group. The skin used in the prior art is usually made of metal, which is easily damaged and corroded.

[0003] Therefore, the utility model provides a new energy heavy truck battery skin group to solve the above technical problems. UTILITY MODEL CONTENT

[0004] The utility model aims to solve the problem that the skin used in the prior art is usually made of metal, which is easily damaged and corroded.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A new energy heavy truck battery skin group includes five skin assemblies, namely left / right skin assemblies, front / rear skin assemblies, and upper skin assemblies. The skin assemblies are used to protect the periphery of the battery. The battery is fixed in a metal frame. The skin assemblies cover the top and the periphery of the frame and are fixed and installed by bolts. The skin assemblies are made of continuous long glass fiber reinforced resin composite material.

[0007] Further, the skin assembly includes:

[0008] The skin plate is made of continuous long glass fiber reinforced resin composite material.

[0009] The edge cover is arranged on the four edges of the skin plate.

[0010] The pressing strip is arranged in the middle of the front / rear skin assembly to limit the position of the skin plate and the metal frame.

[0011] The air hole buckle is made of metal and is connected with the skin plate. The air hole buckle is used to install the skin assembly on the metal frame.

[0012] Further, the edge cover is made of metal or extruded plastic profile.

[0013] Further, the skin plate is added with anti-aging agent and flame retardant during production.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses continuous long glass fiber reinforced resin composite material as the main material. The density of the sheet is only 1 / 5 of that of iron skin and 1 / 2 of that of aluminum alloy skin. Taking a 25-ton truck as an example, the original all-iron battery skin of the whole vehicle weighed 145 kg. After using aluminum alloy skin to reduce weight, the weight was 125 kg. After using composite material skin, the weight was only 55-65 kg, with a weight reduction rate of more than 60%. Due to the lighter weight, the vibration and abnormal noise during vehicle operation can be greatly reduced. After reducing the overall weight of the vehicle, the power consumption per kilometer is reduced, which can increase the driving range or allow more cargo to be carried. Attached Figure Description

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0021] Applicant's design Figs. 1-3 The battery skin assembly shown is for a new energy heavy truck and includes a skin assembly with five sides, namely a left / right skin assembly, a front / rear skin assembly, and an upper skin assembly. The skin assembly is used to protect the battery. The battery is fixed in a metal frame. The skin assembly covers the top and sides of the frame and is fixed by bolts. The skin assembly is made of continuous long glass fiber reinforced resin composite material.

[0022] In this embodiment, the battery skin assembly for the new energy heavy-duty truck can be further optionally comprised of: a skin panel 1, which is made of continuous long glass fiber reinforced resin composite material; an edge band 2, which is disposed on the four sides of the skin panel 1; a pressure strip 3, which is disposed in the middle of the front / rear skin assembly to limit the position of the skin panel 1 and the metal frame; and an air vent buckle 4, which is made of metal and is snapped onto the skin panel 1 to install the skin assembly onto the metal frame; the edge band 2 is made of metal or extruded plastic profile; and anti-aging agents and flame retardants are added to the skin panel 1 during the manufacturing process.
