The bottom of the second arc-shaped main pipe 201 is welded with a second corner connecting piece 202, and the bottom of the seat lower supporting rod 203 is welded with two third connecting plates 214; the fourth elbow pipe 211 has a fourth connecting plate 218 welded to the bottom thereof, and a second handle 212 is mounted to the lower end thereof. The second corner connector 202, the third connecting plate 214 and the fourth connecting plate 218 are all fastened and fixed on the vehicle chassis through screws, so that the whole front frame 2 is ensured to be stably fixed; meanwhile, the two second handrails 212 are installed on the corresponding two fourth elbows 211 in a hoop fixing manner, so that the second handrails 212 are stably fixed.

The other parts of the invention are connected with the two second arc main pipes 201 and the fourth bent pipe 211 in a welding mode to form a front frame 2 which is used for installing decorative plates outside the vehicle, air-conditioning pipelines and related cables for fixing.

The integral structure of the upper frame of the unmanned vehicle is symmetrical, and each structure is made of 304 stainless steel, so that the emission of harmful gas is effectively reduced. The stainless steel pipes and the stainless steel plates corresponding to the frames are preferably made of materials with thin wall thicknesses, the whole vehicle is wrapped by light steel materials under the condition that the overall strength of the frames is guaranteed, the capacity of the whole vehicle for coping with external impact is greatly improved, and meanwhile the weight of the frames is effectively reduced. The frame of whole car parcel still is convenient for install other annexes, and accessible screw or modes such as riveting such as vehicle outward appearance spare, air conditioner, lamps and lanterns and interior are fixed on the frame, and the installation carrier on the frame can also strengthen the bulk strength of frame once more when easy to assemble.
