Specifically, the torsion spring is sleeved on the top plate locking shaft, and two ends of the torsion spring are respectively fixed on two inner side surfaces of the top plate handle 421, and when the top plate locking buckle 423 rotates around the center of the torsion spring relative to the top plate handle 421, the torsion spring generates a torque to pull the top plate locking buckle 423 back to the initial position. When the service man wants to open the roof, the one end of the roof lock 423 is lifted, and the roof lock 423 rotates about the roof lock shaft with respect to the roof handle 421 so that the other end of the roof lock 423 is disengaged from the locker slot 231, thereby opening the roof; when the roof is open state, because the effect of torsional spring, roof hasp 423 resumes initial position, and the middle part butt of roof hasp 423 is on the spacing 422 of hasp, and when the roof fell down, because the reason of roof weight, the other end inclined plane of roof hasp 423 slides in the fore shaft groove 231 along the side of GPS antenna support 23 to make roof hasp 423 lock under the effect of torsional spring, thereby accomplish automatic locking.
The frame assembly provided by the embodiment of the invention mainly comprises four parts, namely an equipment mounting frame assembly, a front frame assembly, a rear frame assembly and a top plate supporting assembly, wherein the equipment mounting frame assembly provides a proper mounting position for electronic devices of a vehicle, and the top plate supporting assembly is movably connected with the rear frame assembly through a top plate opening and closing mechanism, so that the top of the vehicle is conveniently opened, the maintenance of parts and electronic devices in the vehicle is facilitated, and meanwhile, the arrangement of a locking device enables the top of the vehicle to be automatically locked when the top of the vehicle falls down. The strength and the rigidity of the frame are improved on the premise of light weight, the cost is reduced, and parts and electronic devices in the frame can be conveniently overhauled.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
