A front panel assembly includes a front panel body and an identification plate. The identification plate includes a main body marked with a logo and rotatably attached to the panel body, and a weight piece attached to the main body at a bottom of the logo. The main body of the identification plate is made of plastic. The weight piece is made of steel. If the panel body is rotated, gravity acts on the weight piece driving the main body to rotate until the weight piece is toward the ground, thereby making the logo always appear to be upright. |
