Utility Model Content

[0003] The purpose of the utility model is to provide a fixing device for a vehicle mid-mounted power battery in view of the deficiencies in the prior art, thereby solving the problems that the power battery of a new energy light truck is arranged on the side of the frame or behind the cab and occupies a large space, and the side-mounted battery is easily hit.

[0004] The utility model is realized by adopting the following technical solutions:

[0005] A fixing device for a vehicle mid-mounted power battery, comprising a hanger, a connecting plate, a vehicle frame and a battery box;

[0006] The battery box is arranged at the bottom of the two vehicle frames; a plurality of connecting plates are arranged on the two sides of the battery box; and the connecting plates are connected to the vehicle frames via hanging seats.

[0007] Preferably, the cross-section of the hanger is a "J"-shaped structure, and the two free ends of the hanger are respectively connected to the frame and the connecting plate.

[0008] Preferably, a protective plate is further provided at the connection plug-in of the battery box; the protective plate is an L-shaped deformation structure; one end plane of the protective plate is connected to the frame, and the other end plane is connected to the battery box.

[0009] Preferably, the connecting plate includes a U-shaped transition plate and a transition sealing plate, the transition sealing plate is arranged inside the U-shaped opening of the transition plate, and the U-shaped opening of the U-shaped transition plate fits the battery box; the connecting plate is provided with a plurality of battery box mounting holes and a plurality of hanger mounting holes.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model sets the battery box at the bottom of the frame, which can effectively save frame space and avoid the impact risk caused by the side hanging of the power battery; the number of connecting plates and hangers is reasonably selected according to the battery weight and the frame design, which can meet the carrying capacity while making the whole vehicle lighter.
